For example, they can refer to fixed or detachable connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0074] See first Figure 1 and 2 ,in, Figure 1 is a structural diagram of a preferred embodiment of the household appliance balancing device of the present invention, Figure 2 : is a structural diagram of the regulating assembly of the present invention. Figure 1 and 2As shown, the household appliance balancing device of the present invention includes at least one acceleration sensor 5 and multiple adjustment components, and the multiple adjustment components are arranged at the bottom of the household appliance (not shown in the figure), and the adjustment component includes a connected pressure device 11 and an elastic member 12, the pressure device 11 is connected to the household appliance, and the acceleration sensor 5 is arranged at the bottom of the household appliance and is configured to obtain the acceleration generated when the household appliance is offset; the balancing device is configured to control at least one pressure device 11 to apply pressure to the elastic member 12 according to the signal obtained by the acceleration sensor 5.

[0075] Specifically, the number of the adjustment components is four, and the structures of the four adjustment components are the same, namely the first adjustment component 1, the second adjustment component 2, the third adjustment component 3 and the fourth adjustment component 4, and are evenly distributed along the circumference of the bottom of the household appliance. Taking the first adjustment component 1 as an example, the first adjustment component 1 includes a pressure device 11 and an elastic member 12. The upper part of the pressure device 11 is connected to the bottom of the household appliance, and the lower part of the pressure device 11 is connected to the elastic member 12. When the household appliance is offset, the acceleration sensor 5 will transmit the acceleration generated in each area of ​​the bottom of the household appliance to the controller, and the controller will correspondingly control the pressure device in at least one of the adjustment components to apply pressure to the elastic member connected thereto to maintain the balance of the household appliance. For example, Figure 1 The shown direction is the reference direction. If the household appliance deviates forward, the controller controls the pressure device in the second adjusting component 2 to apply pressure, and the elastic member in the second adjusting component 2 is compressed, so that the rear of the bottom of the household appliance moves downward to maintain balance; if the household appliance deviates to the rear, the controller controls the pressure device in the fourth adjusting component 4 to apply pressure, and the elastic member in the fourth adjusting component 4 is compressed, so that the front of the bottom of the household appliance moves downward to maintain balance; if the household appliance deviates to the left, the controller controls the pressure device 11 in the first adjusting component 1 to apply pressure, and the elastic member 12 in the first adjusting component 1 is compressed, so that the right side of the bottom of the household appliance moves downward to maintain balance. If the household appliance deviates to the right, the controller controls the pressure device in the third adjusting component 3 to apply pressure, and the elastic member in the third adjusting component 3 is compressed, so that the left side of the bottom of the household appliance moves downward to maintain balance.

[0076] It should be noted that the present invention does not impose any restrictions on the specific number of the adjustment components, and those skilled in the art can set the number according to actual conditions.

[0077] Furthermore, in a preferred embodiment of the household appliance balancing device, the pressure device 11 includes a pressure portion 111 and a telescopic portion 112, the pressure portion 111 is connected to the household appliance, and the telescopic portion 112 is movably connected to the pressure portion 111, and the telescopic portion 112 can be inserted into the pressure portion 111. When the pressure portion 111 moves in a direction away from the household appliance, that is, when the pressure portion 111 moves downward, the elastic member 12 is in a compressed state; when the pressure portion 111 moves in a direction close to the household appliance, that is, when the pressure portion 111 moves upward, the elastic member is in an extended state, and the elastic member 12 is a spring.

[0078] It should be noted that the present invention does not impose any limitation on the specific type of the elastic member 12. For example, the elastic member 12 may be a spring or an elastic block, and those skilled in the art may set it according to actual conditions.

[0079] In addition, it should be noted that the present invention does not impose any restrictions on the specific structure and model of the controller, and the controller can be either the original controller of the household appliance or a controller separately set up to execute the balance control method of the present invention. Technicians can set the structure and model of the controller according to actual usage requirements.

[0080] Based on the above structural setting, the problem that household appliances are difficult to maintain their own balance state when they generate vibration can be solved. In addition, the present invention also combines the following balance control method to timely and accurately regulate the first adjustment component 1, the second adjustment component 2, the third adjustment component 3 and the fourth adjustment component 4.

[0081] See next Figure 4 , Figure 4 This is a flow chart of the main steps of the balance control method of the present invention. Figure 4 As shown, based on the household appliance balancing device described in the above embodiment, the balancing control method of the present invention includes:

[0082] S1: Obtain the balance state of household appliances;

[0083] S2: According to the balance state of the household appliance, the operating states of the first regulating component, the second regulating component, the third regulating component and the fourth regulating component are controlled accordingly.

[0084] Further, in step S1, in a preferred embodiment, pressure sensors are respectively provided at the four adjustment components at the bottom of the household appliance, and the equilibrium state of the household appliance is judged by obtaining the pressure changes at the four adjustment components. If there is a pressure change at one or two adjacent pressure sensors, it is judged that the household appliance has shifted. If there is no pressure change at all four pressure sensors, it is judged that the household appliance is in a stable state. In another preferred embodiment, a plurality of acceleration sensors 5 are provided at the bottom of the household appliance, and the acceleration sensors 5 can sense the downward acceleration of different areas of the bottom of the household appliance. If at least one of the plurality of acceleration sensors 5 senses acceleration, it is judged that the household appliance has shifted. If none of the plurality of acceleration sensors 5 sense acceleration, it is judged that the household appliance is in a stable state. Those skilled in the art can set it by themselves according to actual conditions.

[0085] Further, in step S2, if the household appliance is in a stable state, the controller controls the four adjustment components not to enter the working state, that is, the pressure device in each adjustment component does not compress the elastic component connected to it; if the household appliance is offset, the controller controls the adjustment component at the offset location not to enter the working state, and the controller controls some or all of the adjustment components at the non-offset location to enter the working state, that is, the pressure device in the adjustment component that enters the working state compresses the elastic component connected to it.

[0086] See next Figures 3 to 5 , Figure 3 is a schematic diagram of a horizontal coordinate system established by two mutually perpendicular straight lines on the horizontal plane where the bottom of the household appliance of the present invention is located, Figure 5 FIG. 1 is a flow chart showing the specific steps of a preferred embodiment of the balance control method of the present invention. Figures 3 to 5 As shown, based on the household appliance balancing device described in the above embodiment, a preferred embodiment of the balancing control method of the present invention specifically includes the following steps:

[0087] S101: Obtaining the downward acceleration A of each point on two mutually perpendicular lines on the plane where the bottom of the household appliance is located;

[0088] S102: Establishing a horizontal coordinate system using two mutually perpendicular straight lines, where one of the two mutually perpendicular straight lines serves as an X-axis of the horizontal coordinate system, and the other of the two mutually perpendicular straight lines serves as a Y-axis of the horizontal coordinate system;

[0089] S103: The point generating acceleration A is located in the positive direction of the X axis and the positive direction of the Y axis;

[0090] S104: determining whether the household appliance is shifting toward the area of ​​the first quadrant;

[0091] S105: The third regulating component enters the working state;

[0092] S106: The point generating acceleration A is located in the negative direction of the X axis and the positive direction of the Y axis;

[0093] S107: Determine whether the household appliance is shifting toward the area of ​​the second quadrant;

[0094] S108: The fourth regulating component enters the working state;

[0095] S109: The point generating acceleration A is located in the negative direction of the X axis and the negative direction of the Y axis;

[0096] S110: Determine whether the household appliance is shifting toward the third quadrant;

[0097] S111: The first regulating component enters the working state;

[0098] S112: The point generating acceleration A is located in the positive direction of the X axis and the negative direction of the Y axis;

[0099] S113: Determine whether the household appliance is shifting toward the fourth quadrant;

[0100] S114: The second regulating component enters the working state;

[0101] S115: The point generating acceleration A is only in the positive direction of the Y axis;

[0102] S116: Determine whether the household appliance is shifted toward the first quadrant and the second quadrant;

[0103] S117: The third adjustment component and the fourth adjustment component enter the working state;

[0104] S118: The point generating acceleration A is only in the negative direction of the Y axis;

[0105] S119: Determine whether the household appliance is shifted toward the third quadrant or the fourth quadrant;

[0106] S120: The first regulating assembly and the second regulating assembly enter a working state;

[0107] S121: The point generating acceleration A is only in the positive direction of the X axis;

[0108] S122: Determine whether the household appliance is shifted toward the first quadrant and the fourth quadrant;

[0109] S123: The second regulating assembly and the third regulating assembly enter a working state;

[0110] S124: The point generating acceleration A is only in the negative direction of the X axis;

[0111] S125: Determine whether the household appliance is shifted toward the second quadrant and the third quadrant;

[0112] S126: The first regulating component and the fourth regulating component enter a working state;

[0113] Furthermore, in step S101, multiple acceleration sensors 5 are evenly arranged on two mutually perpendicular lines at the bottom of the household appliance. The acceleration sensors 5 are used to obtain downward acceleration A at a limited number of points on the two mutually perpendicular lines in the plane of the bottom of the household appliance. In this preferred embodiment, two acceleration sensors 5 are evenly arranged on one of the two mutually perpendicular lines, and two acceleration sensors 5 are evenly arranged on the other of the two mutually perpendicular lines. Of course, it is also possible to evenly arrange four acceleration sensors 5 on one of the two mutually perpendicular lines, and evenly arrange four acceleration sensors 5 on the other of the two mutually perpendicular lines. Those skilled in the art may determine this according to actual circumstances.

[0114] Furthermore, in step S102, a horizontal coordinate system is established using two mutually perpendicular straight lines on the bottom of the household appliance, the center point of the bottom of the household appliance is the center point of the horizontal coordinate system, the center point of the horizontal coordinate system coincides with the intersection of the two mutually perpendicular straight lines, one of the two mutually perpendicular straight lines is the X-axis of the horizontal coordinate system, and the other of the two mutually perpendicular straight lines is the Y-axis of the horizontal coordinate system.

[0115] Continue reading Figure 3 The point on the X-axis of the horizontal coordinate system that produces downward acceleration A is represented by X1, and the point on the Y-axis of the horizontal coordinate system that produces downward acceleration A is represented by Y1. Points that do not produce acceleration are not displayed. The acceleration sensors 5 are set in both the positive and negative directions of the X-axis of the horizontal coordinate system established by the two straight lines, that is, Figure 3 The direction shown is the reference direction. Acceleration sensors 5 are set on the left and right sides of the origin on the X axis. Acceleration sensors 5 are set on the positive and negative directions of the Y axis of the horizontal coordinate system established by the two straight lines. Figure 3 The direction shown is a reference direction, and acceleration sensors 5 are provided above and below the origin on the Y-axis.

[0116] Furthermore, in step S103, if the points on the two mutually perpendicular straight lines generating downward acceleration A are respectively located in the positive directions of the X-axis and the Y-axis of the horizontal coordinate system, specifically, X1 is located in the positive direction of the X-axis of the horizontal coordinate system relative to the origin, that is, X1=(x1, y1), in which case x1>0, y1=0; and Y1 is located in the positive direction of the Y-axis of the horizontal coordinate system relative to the origin, that is, Y1=(x2, y2), in which case x2=0, y2>0. The controller obtains the position coordinates of the points generating the acceleration.

[0117] Further, in step S104, if the acceleration points obtained by the controller are X1 and Y1, and the position coordinates of X1 and Y1 are respectively X1 = (x1, y1), at this time, x1>0, y1=0; Y1 = (x2, y2), at this time, x2=0, y2>0, then the controller determines that the household appliance is offset toward the area of ​​the first quadrant, that is, the household appliance is offset toward the direction of the first adjustment component 1.

[0118] Further, in step S105, if the household appliance shifts toward the area of ​​the first quadrant, the controller controls the third adjustment component 3 to enter the working state, that is, the controller controls the pressure device in the third adjustment component 3 to apply pressure to the elastic member connected thereto, thereby restoring the balance of the household appliance.

[0127] Further, in step S114, if the household appliance shifts toward the area of ​​the fourth quadrant, the controller controls the second adjustment component 2 to enter the working state, that is, the controller controls the pressure device in the second adjustment component 2 to apply pressure to the elastic member connected thereto, thereby restoring the balance of the household appliance.

[0128] Furthermore, in step S115, the points on the two mutually perpendicular lines that generate downward acceleration A are located only in the positive direction of the Y axis of the horizontal coordinate system.

The controller obtains the position coordinates of the point generating the acceleration.

[0132] Further, in step S119, if the acceleration point obtained by the controller is only Y1, and the position coordinates of Y1 are Y1 = (x2, y2), at this time, x2 = 0, y2 < 0, then the controller determines that the household appliance is offset toward the area of ​​the third quadrant and the fourth quadrant, that is, the household appliance is offset toward the direction of the third adjustment component 3 and the fourth adjustment component 4.

[0133] Furthermore, in step S120 , if the household appliance shifts toward the third quadrant and the fourth quadrant, the controller controls both the first adjustment component 1 and the second adjustment component 2 to enter a working state.

[0135] Further, in step S122, if the acceleration point obtained by the controller is only X1, and the position coordinates of X1 are X1 = (x1, y1), at this time, x1>0, y1=0, then the controller determines that the household appliance is offset toward the area of ​​the first quadrant and the fourth quadrant, that is, the household appliance is offset toward the direction of the first adjustment component 1 and the fourth adjustment component 4.

Specifically, at this time, there is no point on the Y-axis of the horizontal coordinate system that generates downward acceleration A, and only X1 is displayed on the coordinate system, that is, X1 is located in the positive direction of the X-axis of the horizontal coordinate system relative to the origin, that is, X1 = (x1, y1), at this time, x1 < 0, y1 = 0; the controller obtains the position coordinates of the point where the acceleration is generated.

[0138] Further, in step S125, if the acceleration generating point obtained by the controller is only X1, and the position coordinates of X1 are X1 = (x1, y1), at this time, x1 < 0, y1 = 0, then the controller determines that the household appliance is offset toward the area of ​​the second quadrant and the third quadrant, that is, the household appliance is offset toward the direction of the second adjustment component 2 and the third adjustment component 3.

[0139] Furthermore, in step S126 , if the household appliance shifts toward the second quadrant and the third quadrant, the controller controls the first adjustment component 1 and the fourth adjustment component 4 to enter a working state.

[0140] In addition, in this preferred embodiment, the balance control method further includes the following steps:

[0141] If no point on the two mutually perpendicular straight lines generates downward acceleration A, that is, no point X1 and no point Y1 appear on the X-axis and Y-axis of the horizontal coordinate system, respectively, the controller determines that the household appliance is in a stable state;

[0142] If the household appliance is in a stable state, the controller controls the first regulating component 1 , the second regulating component 2 , the third regulating component 3 and the fourth regulating component 4 not to enter a working state.

[0143] In addition, as another preferred embodiment of the present invention, the balance control method includes the following steps:

[0144] Step S1001: obtaining a first downward acceleration A1 at a first adjustment component at the bottom of the household appliance, obtaining a second downward acceleration A2 at a second adjustment component at the bottom of the household appliance, obtaining a third downward acceleration A3 at a third adjustment component at the bottom of the household appliance, and obtaining a fourth downward acceleration A4 at a fourth adjustment component at the bottom of the household appliance;

[0145] Step S1002: If the value of the first acceleration A1 is not equal to zero and the values ​​of the second acceleration A2, the third acceleration A3 and the fourth acceleration A4 are all equal to zero, it is determined that the household appliance is deviating toward the area where the first adjustment component is located;

[0146] Step S1003: If the value of the second acceleration A2 is not equal to zero and the values ​​of the first acceleration A1, the third acceleration A3 and the fourth acceleration A4 are all equal to zero, it is determined that the household appliance is deviating toward the area where the second adjustment component is located;

[0147] Step S1004: If the value of the third acceleration A3 is not equal to zero, and the values ​​of the first acceleration A1, the second acceleration A2, and the fourth acceleration A4 are all equal to zero, it is determined that the household appliance is deviating toward the area where the third adjustment component is located;

[0148] Step S1005: If the value of the fourth acceleration A4 is not equal to zero, and the values ​​of the first acceleration A1, the second acceleration A2, and the third acceleration A3 are all equal to zero, it is determined that the household appliance is deviating toward the area where the fourth adjustment component is located;

[0149] Step S1006: If the values ​​of the first acceleration A1 and the second acceleration A2 are not equal to zero, and the values ​​of the third acceleration A3 and the fourth acceleration A4 are both equal to zero, it is determined that the household appliance is deviating toward the area where the first adjustment component and the second adjustment component are located;

[0150] Step S1007: If the values ​​of the first acceleration A1 and the fourth acceleration A4 are not equal to zero, and the values ​​of the second acceleration A2 and the third acceleration A3 are both equal to zero, it is determined that the household appliance is deviating toward the area where the first adjustment component and the fourth adjustment component are located;

[0151] Step S1008: If the values ​​of the second acceleration A2 and the third acceleration A3 are not equal to zero, and the values ​​of the first acceleration A1 and the fourth acceleration A4 are both equal to zero, it is determined that the household appliance is deviating toward the area where the second adjustment component and the third adjustment component are located;

[0152] Step S1009: If the values ​​of the third acceleration A3 and the fourth acceleration A4 are not equal to zero, and the values ​​of the first acceleration A1 and the second acceleration A2 are both equal to zero, it is determined that the household appliance is offset toward the area where the third adjustment component and the fourth adjustment component are located.

[0153] Furthermore, in step S1001, four acceleration sensors 5 are provided, and are respectively provided at positions corresponding to the first adjustment component 1, the second adjustment component 2, the third adjustment component 3 and the fourth adjustment component 4 at the bottom of the household appliance. The values ​​of the first acceleration A1, the second acceleration A2, the third acceleration A3 and the fourth acceleration A4 are respectively obtained through the four acceleration sensors 5.

[0154] Furthermore, in step S1002, step S1003, step S1004, step S1105, step S1006, step S1007, step S1008, and step S1009, the acceleration sensor 5 transmits the value of its own acceleration to the controller, and the controller determines whether the values ​​of the first acceleration A1, the second acceleration A2, the third acceleration A3, and the fourth acceleration A4 are equal to zero. If the acceleration value at a certain place is equal to zero, it proves that there is no offset here. If the acceleration value at a certain place is not equal to zero, it proves that there is an offset here. When an offset occurs, the controller determines the offset area of ​​the household appliance based on whether the values ​​of the first acceleration A1, the second acceleration A2, the third acceleration A3 and the fourth acceleration A4 are equal to zero, and controls the first adjustment component 1, the second adjustment component 2, the third adjustment component 3 and the fourth adjustment component 4 to enter the working state accordingly. The execution method of the balance control method of the second preferred embodiment of the balance control method for controlling the four adjustment components to enter the working state according to the offset area is the same as that in the first preferred embodiment of the balance control method, and will not be repeated here.

[0155] Furthermore, if the values ​​of the first acceleration A1, the second acceleration A2, the third acceleration A3 and the fourth acceleration A4 are all equal to zero, the controller determines that the household appliance is in a stable state; if the household appliance is in a stable state, the controller controls the first adjustment component 1, the second adjustment component 2, the third adjustment component 3 and the fourth adjustment component 4 not to enter the working state.

[0156] It should be noted that, in the two preferred embodiments of the balance control method of the present invention, it can also be that if the household appliance deviates toward one of the first adjustment component 1, the second adjustment component 2, the third adjustment component 3 and the fourth adjustment component 4, the controller controls the other three of the first adjustment component 1, the second adjustment component 2, the third adjustment component 3 and the fourth adjustment component 4 to enter the working state; this specific manner of controlling the operating state of the first adjustment component 1, the second adjustment component 2, the third adjustment component 3 and the fourth adjustment component 4 according to the offset area of ​​the household appliance can be set by those skilled in the art according to actual conditions.
