[0047] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0048] Figure 1 is a schematic diagram of a structure of a household appliance according to an exemplary embodiment, referring to Figure 1 As shown, the household appliance 100 may include:

[0049] A fixed component 110 and a movable component 120, wherein the movable component 120 is configured to move relative to the fixed component 110 after receiving a target force;

[0050] A conductor 130, wherein the conductor 130 is fixedly connected to the moving component 120;

[0051] The eddy current detection sensor 140 is fixedly connected to the fixed component 110 . The eddy current detection sensor 140 is configured to determine the position of the moving component 120 during the movement process by detecting the conductive component 130 . Figure 1The dotted box in shows the positions of the moving part 120 and the conductor 130 before they move. The dotted box only shows a possible position of the moving part 120 before it moves, and is not a limitation on the position of the moving part 120.

[0052] Among them, the eddy current detection sensor 140 is a sensor that can detect the distance of the target object in a non-contact manner based on the Faraday electromagnetic induction principle. Based on the principle of electromagnetic induction, when the magnetic lines of force generated by the inductor coil pass through the metal conductor, the metal conductor will generate an induced current, and it will be a closed loop, similar to the shape of a water eddy current, so it is called an eddy current, also known as the eddy current effect. In general, in the current related technology, the eddy current detection sensor is usually in the form of a probe, which is provided with a small coil, and generates an oscillating electromagnetic field under the control of the sensor. When the probe approaches the object to be measured (which needs to be a conductor), an induced current will be generated on the surface of the object to be measured, thereby generating a reverse electromagnetic field. At this time, the eddy current sensor can judge the distance between the object to be measured and the object to be measured according to the strength of the reverse electromagnetic field.

[0053] like Figure 1 As shown, the eddy current detection sensor 140 provided in the embodiment of the present disclosure includes: a guide rail 141 and an eddy current coil 142 disposed on the guide rail 141, and a controller 143. The extension direction of the guide rail 141 is the same as the movable direction of the moving part 120 (the direction indicated by the arrow in the figure). The eddy current coil 142 is used to generate a magnetic field, and the conductor 130 generates a reverse magnetic field under the action of the magnetic field. The eddy current sensor 140 is used to determine the position of the conductor 130 by detecting the reverse magnetic field.

[0054] The conductor 130 is configured to move along the extension direction of the guide rail 141 during the movement of the moving component 120. The conductor 130 is in direct contact with the guide rail 141, or the distance between the conductor 130 and the guide rail 141 is not greater than a specified distance. For example, the conductor 130 is suspended at a certain distance on the guide rail 141, and the distance does not exceed the specified distance. The conductor 130 can be a metal sheet. The specified distance can be determined based on the magnetic field range generated by the eddy current coil 142 and the magnetic field range of the reverse magnetic field generated by the conductor 130.

[0055] Figure 2 is a schematic diagram of the principle of an eddy current detection sensor according to an exemplary embodiment, referring to Figure 2As shown, the conductor 130 is suspended above the guide rail 141 and does not contact the guide rail 141. After the eddy current sensor 140 is powered on and starts working, it generates a high-frequency signal (such as a high-frequency alternating current) so that the eddy current coil 142 can generate a magnetic field H1 around it. The magnetic field causes the conductor 130 to generate a reverse reverse magnetic field H2. Under the reaction of the reverse magnetic field H2, the amplitude and phase of the high-frequency current in the eddy current coil 142 are changed, thereby changing the effective impedance of the eddy current coil 142. When the moving part 120 moves, the conductor 130 moves with the moving part 120, so that the relative position of the conductor 130 and the guide rail 141 changes, so that the reverse magnetic field H2 generated by the conductor 130 also changes, so that the effective impedance of the eddy current coil 142 also changes with the movement of the conductor 130. In the embodiment of the present disclosure, the conductor 130 is suspended above the guide rail 141 . The advantage of this is that compared with a configuration in which the conductor 130 is in constant contact with the guide rail 141 , the requirement for installation accuracy of the movable component 120 and the conductor 130 can be reduced.

[0056] It should be noted that the impact of the reverse magnetic field H2 on the effective impedance of the eddy current coil 142 is related to the conductivity, magnetic permeability, geometry of the conductor 130, the coil parameters of the eddy current coil 142, the frequency of the high-frequency current in the eddy current coil 142, and the distance between the eddy current coil 142 and the conductor 130.

[0057] Since the effective impedance of the eddy current coil 142 changes, the voltage on the eddy current coil 142 will change. Therefore, the change in its effective impedance can be detected by detecting the voltage of the eddy current coil 142. Therefore, further, the controller 143 in the eddy current sensor 140 may include (not shown in the following device diagram): an oscillation circuit for generating the above-mentioned high-frequency signal, and a detection module for detecting the voltage of the eddy current coil 142.

[0058] The corresponding relationship between the voltage and the position of the conductor 130 can be established in advance. For example, the voltage of the eddy current coil 142 when the conductor 130 is located at various positions of the guide rail 141 can be detected in advance, so that the real-time voltage of the eddy current coil 142 can be detected by the controller 143, and the current position of the conductor 130 can be determined according to the above corresponding relationship. The eddy current detection sensor 140 can be configured to determine multiple continuous positions or multiple discontinuous positions of the moving part 120 during the movement of the moving part 120 by detecting the conductor 130. For example, the current position of the moving part 120 can be determined according to the real-time position of the conductor 130, so that multiple continuous positions of the moving part 120 can be obtained by continuously detecting the voltage of the eddy current coil 142. Among them, the steps of determining the current position of the conductor 130 according to the above corresponding relationship and determining the current position of the moving part 120 according to the real-time position of the conductor 130 can be performed by the above-mentioned controller 143, or the controller 143 sends the detected voltage to the controller of the home appliance, and the controller of the home appliance executes it.

[0059] Optionally, the structure and location of the guide rail 141 in the eddy current detection sensor 140 may be set according to the application scenario. For example, it may include:

[0060] In the first implementation, the moving part 120 is a push-pull moving part, and the guide rail 141 can be set on one side or the bottom of the moving part 120. The guide rail is a linear guide rail. Figure 1 and Figure 2 The guide rail 141 shown. It can be understood that the linear guide rail in the embodiment of the present disclosure is a guide rail used to detect the movement displacement of the moving part 120 in the linear direction. Therefore, in practical applications, a guide rail that has a certain degree of deformation (for example, a certain curvature) in the extension direction of the guide rail but is still used to detect the movement displacement of the moving part in the linear direction can also be understood as a linear guide rail.

[0061] For example, when the household appliance is a refrigerator, the fixed component 110 may be a refrigerator body, and the movable component 120 may be a refrigerator drawer, which may be pulled out of or pushed into the refrigerator body. The guide rail 141 may be disposed on the left side or the right side of the refrigerator drawer, and the conductor 130 may be disposed on the left side or the right side of the refrigerator drawer and located on the same side as the guide rail 141;

[0062] Alternatively, the guide rail 141 may also be disposed at the bottom of the refrigerator drawer. For example, a mounting groove may be disposed at the bottom of the refrigerator drawer on the refrigerator body for mounting the guide rail 141. In this case, the conductor 130 is also disposed at the bottom of the refrigerator drawer, above the mounting groove. The depth of the guide rail 141 in the mounting groove may determine whether the guide rail 141 is in contact with the conductor 130.

[0063] In addition to and outside, any other household appliance with a drawer can adopt the above structure. For example, the household appliance can also be a dishwasher. The fixed component 110 can be the dishwasher body, and the movable component 120 can be the dishwasher drawer. Its implementation method is similar to that of the above-mentioned refrigerator and will not be repeated here.

[0064] Through the above implementation, the real-time position of the drawer-type component in the household appliance can be detected, so that a reminder can be given when its position is abnormal. For example, when the drawer position detected by the above method determines that the drawer is about to be fully pulled out, the household appliance is controlled to output an alarm sound. Or when the drawer position determines that the drawer has not been fully pushed into the household appliance and has stopped moving, an alarm sound can be output. For example, when the refrigerator drawer is not fully pushed into the refrigerator, it is detected that the refrigerator door is closing, and an alarm sound can be output to remind the user to push the refrigerator drawer into the refrigerator before closing the refrigerator door.

[0065] In a second implementation, the moving component 120 is a buoyancy moving component, the guide rail 141 is disposed on one side of the moving component 120, and the guide rail is a linear guide rail disposed along a vertical direction. Figure 1 and Figure 2 The guide rail 141 is shown.

[0066] For example, in the case where the household appliance is a washing machine, the fixed component 110 may be the washing machine body, and the movable component 120 may be a floating component in the washing machine, such as a float or a float block, which is located in the washing machine. A guide is provided in the washing machine to limit the floating component to move only in the vertical direction, such as a guide rail or a conduit provided in the vertical direction. The floating component is provided in the conduit, and the conduit may be connected to the drum of the washing machine by adopting the principle of a communicating vessel, thereby ensuring that the water level inside the conduit is consistent with the water level in the drum of the washing machine.

[0067] When the washing machine starts to take in water, as the floating body rises, the position of the conductor 130 on the floating body can be detected by the eddy current coil 142 on the guide rail 141. Thus, the real-time position of the floating body can be detected, and the water level can be determined. Moreover, multiple continuous positions of the floating body can be obtained through continuous detection, so that the continuous change of the water level can be determined, and the rising speed of the water level can be determined.

[0068] It is worth noting that, in addition to being applied to washing machines, the second implementation method mentioned above can also be applied to any other scenario where liquid level changes need to be measured, such as measuring the liquid level of a fuel tank in a vehicle.

[0069] In the third implementation, the moving part 120 is a rotating moving part, the guide rail is arranged at the top or bottom of the moving part, and the guide rail is an arc-shaped guide rail. For example, for a refrigerator door, usually for a refrigerator door, a rotatable hinge assembly is usually arranged at the top and bottom, and the refrigerator door can be rotatably fixed on the refrigerator body, and the guide rail can be arranged in the top or bottom hinge assembly of the refrigerator door. The conductor 130 is fixedly connected to the side of the refrigerator door connected to the hinge assembly, so that the conductor 130 moves relative to the arc-shaped guide rail as the refrigerator door rotates, and the curvature of the arc-shaped guide rail matches the curvature of the moving track of the conductor 130 as the refrigerator door rotates. Therefore, the position of the conductor 130 can be determined by the above-mentioned method of measuring the voltage of the eddy current coil 142, and the rotation angle of the refrigerator door can be determined according to the position of the conductor 130.

[0070] For any of the above three implementations, the controller 143 and the guide rail 141 in the eddy current sensor 140 can be connected as one piece, or can be installed in different positions in the household appliance in a distributed structure and connected by wires.

[0071] It is also worth mentioning that the above-mentioned household appliance may include multiple moving parts 120, and correspondingly, the guide rails 141 may also be multiple, and each moving part 120 is provided with a conductor 130 corresponding to one guide rail 141. That is, multiple moving parts 120 correspond to multiple guide rails 141, and the multiple guide rails 141 may belong to multiple eddy current sensors 140 respectively, or may belong to the same eddy current sensor 140.

[0072] The above technical solution provides a household appliance, comprising: a fixed component and a moving component, wherein the moving component is configured to move relative to the fixed component after receiving a target force; a conductor, wherein the conductor is fixedly connected to the moving component; and an eddy current detection sensor, wherein the eddy current detection sensor is fixedly connected to the fixed component, and wherein the eddy current detection sensor is configured to determine the position of the moving component during movement by detecting the conductor. The above technical solution can solve the problem that only fixed-point detection is possible in the related art, and can achieve the purpose of detecting any position of the moving component in the household appliance during movement, thereby improving the detection accuracy.

[0073] Figure 3is a flow chart of a method for controlling a household appliance according to an exemplary embodiment. Figure 3 As shown, this method can be applied to Figure 1 or Figure 2 The household appliance shown in the figure, the method includes:

[0074] In step S11, the position of the moving part detected by the eddy current detection sensor is obtained. The eddy current detection sensor can be the eddy current detection sensor 100, and the method of detecting the position of the moving part during movement is the same as the method described above, which will not be repeated.

[0075] In step S12, based on the position, a target device of the home appliance is controlled to operate.

[0076] Among them, obtaining the position of the moving part during the movement detected by the eddy current detection sensor may include: obtaining multiple positions of the moving part during the movement detected by the eddy current detection sensor, and the multiple positions are multiple continuous positions or multiple non-continuous positions.

[0077] Optionally, the target device may include a display screen or an indicator light. Accordingly, step S12 may include:

[0078] Based on the multiple positions, obtaining prompt information related to the moving component;

[0079] And, the prompt information is outputted through the display screen or indicator light. The prompt information may be the real-time position of the moving component determined based on the multiple positions, or may be prompt information such as the moving speed of the moving component determined based on the multiple positions.

[0080] For example, the household appliance is a refrigerator or a dishwasher, and the display screen or indicator light is set on the refrigerator or the dishwasher, and the display screen can be controlled to output the prompt information to prompt the real-time position of the refrigerator drawer or the dishwasher drawer; or the prompt light can be displayed in a specific color for prompting, such as green to indicate that the refrigerator drawer or the dishwasher drawer has been put back to the correct position, yellow to indicate that the drawer is pulled out, etc.; or the prompt light can be controlled to flash, and the flashing frequency is proportional to the moving speed of the refrigerator drawer or the dishwasher drawer. Optionally, while outputting the above prompt information, a voice prompt related to the prompt information can also be output synchronously.

[0081] For example, the household appliance may be a washing machine, the moving component may be a floating component inside the washing machine, and the target device may be a water level controller. The structure and working principle of the floating component may refer to the buoyancy moving component in the second implementation mode, and will not be described in detail.

[0082] Based on the multiple positions of the float, the water level information of the washing machine corresponding to each position information can be determined respectively, so as to control the operation of the water level controller according to the water level information, for example, to control the water intake or stop the water intake of the washing machine.

[0083] Optionally, before obtaining the position of the moving component detected by the eddy current detection sensor in step S11, the following method may be further included:

[0084] Receive a trigger instruction from the home appliance.

[0085] In response to the trigger instruction, the position of the moving component during the movement detected by the eddy current detection sensor is acquired.

[0086] For example, the trigger instruction may be triggered after the home appliance is awakened, for example, after detecting that the door of the refrigerator is opened, the trigger instruction is generated, and the trigger instruction triggers the eddy current detection sensor to power on and start detection to obtain the position of the moving part during the movement. That is, it can be understood that the eddy current detection sensor may not work when the home appliance is not awakened, thereby saving power and avoiding unnecessary waste.

[0090] Optionally, the acquisition module 401 is configured to: acquire a plurality of positions of the moving component during movement detected by the eddy current detection sensor, where the plurality of positions are a plurality of continuous positions or a plurality of discontinuous positions.

[0091] Optionally, the target device includes a display screen or an indicator light, and the control module 402 may be configured to: obtain the prompt information related to the moving component based on the multiple positions;

[0092] The prompt information is output through the display screen or indicator light.

[0093] Optionally, the household appliance is a washing machine, the moving component is a floating component inside the washing machine, and the target device is a water level controller;

[0094] Based on the multiple positions, respectively determine the water level information of the washing machine corresponding to each position information;

[0097] Receiving a trigger instruction of the household appliance;

[0098] In response to the trigger instruction, the position of the moving component during the movement detected by the eddy current detection sensor is acquired.

[0099] Through the above technical solution, the problem that only fixed-point detection can be performed in the related art can be solved, and the purpose of detecting any position of the moving parts in the household appliance during the movement process can be achieved, thereby improving the detection accuracy.
