With the progress of society and the improvement of living standard of people, household appliances with large volume such as ultrathin large-volume refrigerator are increasingly accepted by people, and the market share is continuously improved. However, as the thickness of the refrigerator decreases and the height increases, the stability of the refrigerator is deteriorated, and if the refrigerator is overloaded or the storage position of the articles is unbalanced, particularly when too many articles are placed in the refrigerator door, the refrigerator door is liable to fall down. And the larger the refrigerator volume under the same size, the more materials such as vacuum insulation panels are used, the larger the weight of the refrigerator, especially the weight of a door is increased, and the risk of the refrigerator toppling is increased.

At present, users usually observe the inclination condition of the refrigerator by naked eyes, but cannot observe slight inclination by naked eyes, and the serious consequence of the inclination is tilting, so that the tilting risk of the refrigerator cannot be found timely, and the household appliance tilting is not only loss of equipment property, but also has potential safety hazard.

In addition, at present, the refrigerator is usually prevented from tilting forward by manually adjusting the front foot and the rear foot of the refrigerator to slightly tilt backward, and after a user observes that the refrigerator is tilted, the user also usually manually adjusts the refrigerator to a stable state, so that the manual adjustment operation is complex, and different requirements under different tilting conditions are not met.

Referring to fig. 1 to 3, an embodiment of the present disclosure provides a tilt detection device including a conductive plate 10 and a movable conductor 20, the conductive plate 10 being provided with a first wiring portion 11, the conductive plate 10 being internally adapted to be supplied with current; the movable conductor 20 is provided with a second wiring portion 21 electrically connected to the first wiring portion 11, and the movable conductor 20 is provided on the conductive plate 10 and is movable in the longitudinal direction of the conductive plate 10 to change the magnitude of the current between the first wiring portion 11 and the second wiring portion 21.

The movable conductor 20 is disposed on the conductive plate 10, the movable conductor 20 contacts the conductive plate 10, and the first connection portion 11 of the conductive plate 10 is connected to the second connection portion 21 of the movable conductor 20, so that when a current is applied to the conductive plate 10, a current loop is formed between the conductive plate 10 and the movable conductor 20.

Alternatively, a weak current is supplied to the inside of the conductive plate 10.

The first and second connection portions 11 and 21 are connected to the positive or negative electrode of the power supply 60, respectively. In the case where the first connection portion 11 is connected to the positive electrode of the power supply 60, a current flows from the first connection portion 11 into the conductive plate 10, the current flows in the longitudinal direction of the conductive plate 10, flows through the movable conductor 20, the second connection portion 21 provided on the movable conductor 20 is electrically connected to the first connection portion 11, and the current flows back to the negative electrode of the power supply 60 through the second connection portion 21, forming a closed circuit. It will be appreciated that the first connection portion 11 may be connected to the negative electrode of the power source 60, the second connection portion 21 is connected to the positive electrode of the power source 60, and the current flows from the second connection portion 21 through the movable conductor 20 and then into the conductive plate 10, and flows from the first connection portion 11 back to the negative electrode of the power source 60 to form a closed loop.

As the conductive plate 10 tilts, electrical parameters such as resistance, current, etc. in the circuit change. As shown in fig. 1 to 3, the ammeter 70 is connected between the first wiring portion 11 and the second wiring portion 21, and the change in current in the circuit can be detected, and the inclination state of the conductive plate 10 can be determined by the change in current. The arrow direction in the figure indicates the flow direction of the current.

As shown in fig. 1, when the conductive plate 10 is in a balanced state, the movable conductor 20 does not move relative to the conductive plate 10, and the resistance in the loop is unchanged, so the current is unchanged.

As shown in fig. 3, when the conductive plate 10 is inclined toward the direction in which the first wiring portion 11 is located, the movable conductor 20 moves along the conductive plate 10 toward the first wiring portion 11, and the length of the conductive plate 10 between the first wiring portion 11 and the second wiring portion 21 becomes small, so that the resistance in the circuit becomes small, and thus the current becomes large.

As shown in fig. 2, when the conductive plate 10 is inclined away from the position of the first wiring portion 11, the movable conductor 20 moves along the conductive plate 10 away from the first wiring portion 11, and the length of the conductive plate 10 between the first wiring portion 11 and the second wiring portion 21 becomes large, so that the resistance in the circuit becomes large, and the current becomes small.

It is understood that the inclined state of the conductive plate 10 may also be judged by detecting the change in resistance between the first wiring portion 11 and the second wiring portion 21.

With the tilt detection device provided by the embodiment of the present disclosure, when the conductive plate 10 is tilted, the movable conductor 20 can move along the length direction of the conductive plate 10 under the action of gravity, so that the length of the conductive plate 10 between the first wiring portion 11 and the second wiring portion 21 is changed, thereby changing the resistance in the loop, and being capable of changing the magnitude of the current between the first wiring portion 11 and the second wiring portion 21. The direction and degree of inclination of the conductive plate 10 are different, and the direction and position in which the movable conductor 20 moves on the conductive plate 10 are different. By detecting the current change between the first wiring portion 11 and the second wiring portion 21, the inclination direction and the inclination degree of the conductive plate 10 can be determined, and the recognition accuracy of the inclination condition is improved.

Optionally, the movable conductor 20 is slidably connected to the conductive plate 10.

The movable conductor 20 may be a slider structure, and a guide rail is provided on the conductive plate 10 along the length direction of the conductive plate 10, and the slider is electrically connected with the guide rail. When the guide rail is inclined, the slider slides along the guide rail, and the magnitude of the current between the first wiring portion 11 and the second wiring portion 21 can be changed.

Alternatively, the movable conductor 20 is in rolling connection with the conductive plate 10.

The movable conductor 20 may have a gear structure, and a rack structure is provided on the conductive plate 10, and the gear is electrically connected to the rack. When the rack is inclined, the pinion rolls along the rack, and the magnitude of the current between the first wiring portion and the second wiring portion 21 can be changed.

The gear assembly 22 is engaged with the rack 12, and the gear assembly 22 is movable toward one end of the rack 12 in the length direction of the rack 12 when the rack 12 is tilted. When the gear assembly 22 moves toward one end of the rack 12 along the length direction of the rack 12, the position of the gear assembly 22 on the rack 12 changes, and the resistance between the first and second junction portions 21 changes, so that the current between the first and second junction portions 21 changes.

The movable conductor 20 may be a ball structure, and a guide rail is provided on the conductive plate 10 along the length direction of the conductive plate 10, and the ball is electrically connected with the guide rail. When the guide rail is inclined, the ball rolls along the guide rail, and the magnitude of the current between the first wiring portion 11 and the second wiring portion 21 can be changed.

Alternatively, the second wiring portion 21 is provided at the center of the movable conductor 20.

When the movable conductor 20 is connected to the conductive plate 10 by rolling, the movable conductor 20 rolls on the conductive plate 10, and the electrical connection position of the surface of the movable conductor 20 changes. The distance between the other parts of the movable conductor 20 and the conductive plate is constantly changing except for the center position. The second connection portion 21 is provided at the center of the movable conductor 20, and can eliminate the change in internal resistance of the movable conductor 20 in the loop portion, which affects the current in the loop. As shown in connection with fig. 1 to 3, the second wire connecting portion 21 is provided at the center of the gear assembly 22.

When the movable conductor 20 is slidably connected to the conductive plate 10, the movable conductor 20 slides on the conductive plate 10, and the electrical connection position of the surface of the movable conductor 20 does not change, and at this time, the second connection portion 21 may be provided at the center of the movable conductor 20 or may be provided on the surface of the movable conductor 20.

Alternatively, the first wiring portion 11 is provided at an end portion of the conductive plate 10 in the own length direction.

When the first wiring portion 11 is provided at either one of both ends of the conductive plate 10 in the longitudinal direction, the movable range of the movable conductor 20 is large, so that the detection range of the degree of inclination is large, which can enhance the detection effect. Further, the first wiring portion 11 is provided at the end portion of the conductive plate 10 in the longitudinal direction thereof, and can avoid the obstruction of the movement of the movable conductor 20.

Optionally, as shown in connection with fig. 1 to 3, the inclination detection device further includes a limiting member 30, where the limiting member 30 is provided on the conductive plate 10 and/or the movable conductor 20, for limiting a range of movement of the movable conductor 20 on the conductive plate 10 along a length direction of the conductive plate 10.

The movable conductor 20 is restrained by the restraining member 30 so that the movable conductor 20 moves within a range set on the conductive plate 10, and the movable conductor 20 can be prevented from moving beyond the conductive plate 10.

The stopper 30 may be a stopper 33 or a structure such as a bar or a blocking piece.

The two ends of the length direction of the conductive plate 10 are provided with the limiting pieces 30, the movable conductor 20 can move between the first limiting piece 31 and the second limiting piece 32 along the length direction of the conductive plate 10, and the movement range of the movable conductor 20 is more definite by limiting the common range of the first limiting piece 31 and the second limiting piece 32.

As shown in conjunction with fig. 4 to 13, an embodiment of the present disclosure provides a home appliance including a main body 40 and the above-described inclination detecting device; the inclination detection device is provided to the main body 40 for detecting inclination information of the main body 40.

The household appliance provided by the embodiment of the disclosure, because of including the inclination detection device according to any one of the embodiments, has all the advantages of the inclination detection device according to any one of the embodiments, and is not described herein again.

The household appliances can be refrigerators, freezers, air conditioners, washing machines, etc. The household appliance is provided with a supporting base angle arranged at the bottom of the main body 40, and the horizontal line where the supporting base angle is in contact with the ground is a overturning line. When the center of gravity of the entire household appliance is located on one side of the direction of the overturning line toward the main body 40 and the distance between the center of gravity and the overturning line is greater than or equal to the first threshold value, the main body 40 is in a balanced state. When the center of gravity of the whole household appliance is located at one side of the overturning line facing the direction of the main body 40 and the distance between the center of gravity and the overturning line is smaller than a second threshold, the household appliance is poor in stability, and the main body 40 is in an inclined state, wherein the first threshold is larger than the second threshold. For example, when the refrigerator door is opened such that the refrigerator is slightly inclined but not inclined, the refrigerator is in an inclined state. When the center of gravity of the entire household appliance is located at a side of the overturning line away from the main body 40, the main body 40 is in an overturning state.

Alternatively, the conductive plate 10 is provided to the main body 40 and the length direction of the conductive plate 10 is the front-rear direction.

The inclination detection device is provided in the main body 40, and the longitudinal direction of the conductive plate 10 is the front-rear direction, which coincides with the front-rear direction of the main body 40, so that the inclination of the main body 40 in the front-rear direction can be determined by the inclination state of the inclination detection device. The movable conductor 20 is stationary relative to the conductive plate 10 when the body 40 is in a balanced state. The movable conductor 20 moves toward the front of the main body 40 with respect to the conductive plate 10 while the main body 40 is in the forward tilted state; when the main body 40 is in the reclined state, the movable conductor 20 moves toward the rear of the main body 40 with respect to the conductive plate 10.

The conductive plate 10 includes a front end side and a rear end side in the length direction. Next, the inclination detection of the main body 40 will be described by taking the example in which the first wiring portion 11 is located on the rear end side of the conductive plate 10 and the ammeter 70 is connected between the first wiring portion 11 and the second wiring portion 21.

Referring to fig. 4, when the main body 40 is in the balanced state, the conductive plate 10 is in the balanced state, the movable conductor 20 is stationary with respect to the conductive plate 10, and the current in the loop is the initial current. Thus, when the current is unchanged, it is determined that the main body 40 is in the balanced state.

As shown in fig. 5, when the main body 40 is in the forward tilted state, the conductive plate 10 is also in the forward tilted state, and the movable conductor 20 moves along the conductive plate 10 toward the front end side of the conductive plate 10, that is, away from the first wiring portion 11. At this time, the length of the conductive plate 10 between the first wiring portion 11 and the second wiring portion 21 becomes large, so that the resistance in the loop becomes large, and thus the current becomes small, and the first present current detected by the ammeter 70 is smaller than the initial current. Therefore, when the current becomes small, it is determined that the main body 40 is in the forward tilting state.

As shown in fig. 7, when the main body 40 is in the reclined state, the conductive plate 10 is also in the reclined state, and the movable conductor 20 moves along the conductive plate 10 toward the rear end side of the conductive plate 10, that is, toward the first wiring portion 11. At this time, the length of the conductive plate 10 between the first wiring portion 11 and the second wiring portion 21 becomes small, so that the resistance in the loop becomes small, and thus the current becomes large, and the second present current detected by the ammeter 70 is larger than the initial current. Therefore, when the current becomes large, it is determined that the main body 40 is in the backward inclined state.

Optionally, as shown in connection with fig. 4 to 13, the home appliance further includes a leveling assembly 50 and a controller, the leveling assembly 50 being connected with the main body 40 for leveling the main body 40; the controller is connected with the inclination detection device and the leveling assembly 50, and is used for controlling the leveling assembly 50 to level the main body 40 according to detection information of the inclination detection device.

The inclination detection device can detect the electrical parameter information in the loop, the inclination detection device transmits the detected electrical parameter information to the control system controller, and the controller judges the inclination state of the main body 40 according to the change condition of the electrical parameter information, so that the leveling assembly 50 is controlled to work, the position of the main body 40 is leveled, and meanwhile, the inclination detection device returns to the initial balance state. In this way, self-leveling of the body 40 can be achieved.

Alternatively, as shown in connection with fig. 4 to 8, the leveling assembly 50 includes a weight 51, the weight 51 being supported below the main body 40, the weight 51 including a front end 511 and a rear end 512, the weight 51 being movable relative to the main body 40 between an anti-forward-leaning position in which a bottom surface of the front end 511 is higher than a bottom surface of the rear end 512, and an anti-backward-leaning position in which a bottom surface of the front end 511 is lower than a bottom surface of the rear end 512; an adjustment mechanism 52 is drivingly connected to the weight 51 for adjusting movement of the weight 51 relative to the body 40 between the anti-recline position and the anti-recline position.

As shown in fig. 4, the main body 40 is in a balanced state, and the weight 51 is in a balanced position, and the bottom surface of the front end portion 511 is at the same height as the bottom surface of the rear end portion 512.

As shown in fig. 5, when the main body 40 is in the forward tilting state, the rear end portion 512 of the weight 51 is pressed against the ground, the front end portion 511 of the weight 51 moves upward, the weight 51 moves to the forward tilting preventing position, and at this time, the bottom surface of the front end portion 511 is higher than the bottom surface of the rear end portion 512, the center of gravity of the weight 51 moves rearward, the friction between the rear end portion 512 and the ground increases, and the forward tilting of the main body 40 can be blocked. After the forward tilting trend is stopped, the main body 40 of the household appliance continues to move backward under the action of the balance weight 51, and at this time, the front end 511 moves downward, the rear end 512 moves upward, but still contacts the ground, so that the pressure of the rear end 512 to the ground is reduced, the balance weight 51 is located at the leveling position as a whole, and the center of gravity of the whole household appliance is driven to gradually move toward the balancing position. The weight 51 is further height-adjusted until the weight 51 moves to the equilibrium position shown in fig. 4, driving the body 40 to move to the equilibrium state, and leveling the position of the body 40.

As shown in fig. 7, when the main body 40 is in the reclined state, the front end 511 of the weight 51 is pressed against the ground, the rear end 512 of the weight 51 moves upward, the weight 51 moves to the anti-recline position, and at this time, the bottom surface of the front end 511 is lower than the bottom surface of the rear end 512, the center of gravity of the weight 51 moves forward, the friction between the front end 511 and the ground increases, and the main body 40 can be prevented from tilting backward. After the backward tilting trend is stopped, as shown in fig. 8, the main body 40 of the household appliance continues to move forward under the action of the balance weight 51, and at this time, the rear end portion 512 moves downward, and the front end portion 511 moves upward, but still contacts the ground, so that the pressure of the front end portion 511 to the ground is reduced, the balance weight 51 is located at the leveling position as a whole, and the center of gravity of the whole household appliance is driven to gradually move toward the balancing position. The weight 51 is further height-adjusted until the weight 51 moves to the equilibrium position shown in fig. 4, driving the body 40 to move to the equilibrium state, and leveling the position of the body 40.

The first adjusting support bar 521 and the second adjusting support bar 522 further adjust by extending or contracting, so as to drive the balance weight 51 to further adjust the height until the balance weight 51 moves to the balance position as shown in fig. 4, drive the main body 40 to move to the balance state, and level the position of the main body 40.

Under the combined action of the first adjusting support bar 521 and the second adjusting support bar 522, the balance weight 51 is driven to move to the backward tilting prevention position, at this time, the bottom surface of the front end portion 511 is lower than the bottom surface of the rear end portion 512, the center of gravity of the balance weight 51 moves forward, the friction between the front end portion 511 and the ground increases, and the backward tilting of the main body 40 can be blocked.

As shown in fig. 12, when the main body 40 is in the reclined state, the loading block 53 is moved toward the front side of the bottom of the main body 40 in the width direction of the main body 40.

Optionally, the household appliance further comprises a reminding device, wherein the reminding device is connected with the controller and is used for sending out prompt information corresponding to the detection information of the inclination detection device.

According to the parameter information of the household appliance, the threshold value of the inclination detection device of the main body in the toppling critical state can be determined. According to the critical parameter when the main body tilts forward, a first threshold current of the tilting detection device is set, and the current becomes smaller when the main body tilts forward, so the first threshold current is the minimum limit value of the current, and when the first current is smaller than the first threshold current, the main body is determined to be in a forward tilting state. And setting a second threshold current of the inclination detection device according to a critical parameter when the main body is inclined backwards, wherein the first threshold current is the maximum limit value of the current because the current becomes larger when the main body is inclined backwards, and determining that the main body is in a backward inclined state when the second current is larger than the second threshold current.

Alternatively, it is also possible to judge whether the main body is in a tilted state or a toppled state, based on the rate of change of the electrical parameter per unit time. When the main body is in an inclined state, the change of the electrical parameter in unit time is slow. When the main body is in a toppling state, the change of the electrical parameter in unit time is quick. For example, the current fluctuation in the unit time is detected, and the current fluctuation in the unit time is small when the main body is in the inclined state. When the main body is in a toppling state, the current fluctuation in unit time is large.

When the controller determines that the main body 40 is in the toppling state according to the detection information, the controller controls the reminding device to send out reminding information to remind a user that the main body 40 of the household appliance is in the toppling state, so that the user can conveniently adjust the storage articles of the household appliance or the placement position of the household appliance. The alert device may be an alarm device (e.g., an alarm light, beep) or a display device (displaying text or pictures). The reminding device sends out the dumping prompt and can timely respond to the excessive inclination problem.
