[0028] See also Figure 1 and Figure 2 The door switch assembly 3 includes a magnetic part, a moving part 33 and a driving mechanism 34. The driving mechanism 34 and the moving part 33 are fixedly connected. The magnetic part includes a first magnetic part 31 and a second magnetic part 32. The first magnetic part 31 and the second magnetic part 32 are correspondingly arranged, and the corresponding phases of the first magnetic part 31 and the second magnetic part 32 are the same or opposite; the driving mechanism 34 drives the moving part 33 to move between an initial position and a target position. In the initial position, the moving part 33 is located between the first magnetic part 31 and the second magnetic part 32. When the moving part 33 is located at the target position, there is no obstruction between the first magnetic part 31 and the second magnetic part 32.

[0029] In a specific embodiment, the door switch assembly 3 can be an embedded design, specifically, the moving member 33 and the driving mechanism 34 can be embedded in the door body 2 or the kitchen appliance body 1. The first magnetic member 31 and the second magnetic member 32 have the same or opposite phases, and the first magnetic member 31 and the second magnetic member 32 can both be electromagnets. The magnetic poles corresponding to the first magnetic member 31 and the second magnetic member 32 can be controlled by current to make the magnetic poles corresponding to the first magnetic member 31 and the second magnetic member 32 the same or opposite, so that they can repel or attract each other, so that the door body 2 is opened or closed.

[0030] Specifically, the driving mechanism 34 may include a driving motor and an output shaft. The output shaft and the moving part 33 are fixedly connected. The driving motor and the output shaft are connected. The driving motor and the output shaft may be indirectly connected through a synchronous belt, gears, etc., or may be directly connected.

[0031] Specifically, the moving part 33 is provided with a magnetic shielding material, and the magnetic shielding material may include molybdenum-nickel alloy, iron-silicon-aluminum alloy and soft ferrite, etc., and may be applied in different forms (such as thin plates, foils, shells, etc.).

[0032] In practical applications, in order to achieve better magnetic shielding effects, a multi-layer structure design can be adopted, and good contact between the magnetic shielding material and the shielded object can be ensured to reduce magnetic leakage. In addition, the design of magnetic shielding can also combine structural features, including using a closed magnetic conductive shell to "capture" and redirect magnetic field lines, or adding sufficient thickness to ensure that the material does not reach magnetic saturation within the operating frequency range.

[0033] Optional, such as Figure 2 As shown, two groups of door switch assemblies 3 can be set, wherein the two magnetic parts in one group of door switch assemblies 3 have opposite magnetic poles, and the two magnetic parts in the other group of door switch assemblies 3 have the same magnetic poles. By controlling the movement of the moving parts 33 in different switch assemblies, stable opening and stable closing of the door 2 can be achieved.

[0034] Specifically, the first magnetic member 31 includes a first sub-magnetic member and a second sub-magnetic member, the second magnetic member 32 includes a third sub-magnetic member and a fourth sub-magnetic member, the moving member 33 includes a first moving member 33 and a second moving member 33, the driving mechanism 34 includes a first driving mechanism 34 and a second driving mechanism 34, the first moving member 33 and the first driving mechanism 34 are fixedly connected, and the second moving member 33 and the second driving mechanism 34 are fixedly connected; the first sub-magnetic member and the third sub-magnetic member are correspondingly arranged, the second sub-magnetic member and the fourth sub-magnetic member are correspondingly arranged, the first phase relationship and the second phase relationship are different, the first phase relationship is the phase relationship between the first sub-magnetic member and the third sub-magnetic member, and the second phase relationship is the phase relationship between the second sub-magnetic member and the fourth sub-magnetic member. The phase relationship between the four sub-magnetic components; the first driving mechanism 34 drives the first moving component 33 to move between a first initial position and a first target position, and in the first initial position, the first moving component 33 is located between the first sub-magnetic component and the third sub-magnetic component, and when the first moving component 33 is located at the first target position, there is no obstruction between the first sub-magnetic component and the third sub-magnetic component; the second driving mechanism 34 drives the second moving component 33 to move between a second initial position and a second target position, and in the second initial position, the second moving component 33 is located between the second sub-magnetic component and the fourth sub-magnetic component, and when the second moving component 33 is located at the second target position, there is no obstruction between the second sub-magnetic component and the fourth sub-magnetic component.

[0035] The embodiment of the present application also provides a kitchen appliance, including a kitchen appliance body 1, a door body 2, a control device and the above-mentioned door body switch assembly 3, the kitchen appliance body 1 and the door body 2 are rotatably connected, the first magnetic member 31 is fixedly arranged on the door body 2, the second magnetic member 32 is fixedly arranged on the kitchen appliance body 1, and the control device and the driving mechanism 34 are electrically connected; a sensing device is arranged on the door body 2, the sensing device includes an interactive module and a first position sensing module, the interactive module and the first position sensing module are electrically connected to the control device respectively; the first position sensing module is a module for collecting position information of an object using the kitchen appliance.

[0036] In a specific embodiment, the interaction module is used to collect interaction information between the user and the kitchen appliance, and the first position sensing module is used to collect position information of the user of the kitchen appliance. The first position sensing module may include devices such as cameras and radars; during the door closing process, if the camera or radar detects that the distance between the user and the door body 2 is less than or equal to a certain distance, or the user's hand is between the door body 2 and the kitchen appliance body 1, the door closing operation is not performed to avoid the risk of pinching the hand during the door closing process, otherwise the door closing operation is performed. During the door opening process, if the camera or radar detects that the distance between the user and the door body 2 is less than or equal to a certain distance, the door opening operation is not performed to avoid the user being hit by the door body 2 during the door opening process, otherwise the door opening operation is performed. The above distances can be set according to actual application requirements.

[0037] Optionally, the interaction module includes a voice interaction module and / or a motion interaction module, and the voice interaction module and the motion interaction module are electrically connected to the control device respectively.

[0038] Specifically, the voice interaction module is used to collect the voice information of the user and output voice prompt information; the motion interaction module is used to detect the motion interaction information between the user and the kitchen appliance. The motion interaction module may include a camera and an accelerometer, etc. The accelerometer can collect the motion interaction information between the user and the door body 2, such as whether the user knocks on the door body 2. The voice interaction module can collect the voice information of the user, such as opening and closing the door, and send it to the control device, so as to control the magnetic pole of the magnetic part and realize the automatic opening and closing of the door body 2. The voice interaction module can also output voice reminders during the process of opening or closing the door to remind the user to stay away from the door body 2.

[0039] Optionally, the sensing device further includes a second position sensing module, and the second position sensing module is electrically connected to the control device.

[0040] Specifically, the second position sensing module is used to collect the position information of the door body 2, and the second position sensing module may include a Hall sensor and a micro switch, etc. Both the Hall sensor and the micro switch can be set on the door body 2. During the door closing process, if the Hall sensor detects that the distance between the door body 2 and the main body of the kitchen appliance is greater than or equal to a certain distance, the door closing operation will not be performed to avoid the risk of pinching the hand during the door closing process, otherwise the door closing operation will be performed; if the micro switch is not closed, that is, the distance between the door body 2 and the main body of the kitchen appliance is greater than or equal to a certain distance, the door closing operation will not be performed to avoid the risk of pinching the hand during the door closing process, otherwise the door closing operation will be performed. The above distance can be the minimum distance between the door body 2 and the main body of the kitchen appliance that allows the user's hand to be inserted.

[0041] In actual applications, corresponding door opening and closing operations can be performed based on the user's behavior information. When the behavior information indicates that the door body 2 needs to be opened, such as when the user says "open the door", "close the door" and other instructions or the user knocks on the door body 2, the movable member 33 is moved away from between the first magnetic member 31 and the second magnetic member 32 to a position that does not block the first magnetic member 31 and the second magnetic member 32. At this time, the magnetic poles of the first magnetic member 31 and the second magnetic member 32 are the same, so that the door body 2 opens under the action of mutual repulsion between the two magnetic members. After the door body 2 reaches the maximum open position, the movable member 33 is moved back between the first magnetic member 31 and the second magnetic member 32 to prevent the repulsion of the magnetic materials from causing subsequent difficulties in closing the door, and also to prevent the magnetic member from attracting other objects containing magnetic materials.

[0042] When the door body 2 needs to be opened, it is possible to determine whether there is a person near the kitchen appliance based on a camera or radar or other equipment installed on the kitchen appliance, and collect their location information to further determine the distance between the user and the door body 2. When the distance is large, the movable part 33 is controlled to move away from between the first magnetic part 31 and the second magnetic part 32 to a position that does not block the first magnetic part 31 and the second magnetic part 32, thereby opening the door body 2 to avoid hitting the user during the opening process of the door body 2.

[0043] When the behavior information indicates that the door body 2 needs to be closed, the movable member 33 is moved away from between the first magnetic member 31 and the second magnetic member 32 to a position where the first magnetic member 31 and the second magnetic member 32 are not blocked. At this time, the magnetic poles of the first magnetic member 31 and the second magnetic member 32 are opposite, so that the door body 2 is closed under the action of the mutual attraction of the two magnetic members. After the door body 2 is completely closed, the movable member 33 is moved back between the first magnetic member 31 and the second magnetic member 32 to prevent the magnetic material from being attracted and causing difficulty in subsequent door opening.

[0044] When the door body 2 needs to be closed, the position information of the door body 2 can be determined based on a device such as a camera or radar installed on the kitchen appliance, and then the distance information between the door body 2 and the kitchen appliance body 1 can be determined. When the distance information is less than a preset distance threshold, that is, when the distance between the door body 2 and the kitchen appliance body 1 is small, the moving part 33 is controlled to move away from between the first magnetic part 31 and the second magnetic part 32 to a position that does not block the first magnetic part 31 and the second magnetic part 32, so that the door body 2 is closed to avoid the risk of pinching the hand during the closing process of the door body 2. The above-mentioned preset distance threshold can be set according to actual application requirements, for example, it can be the minimum distance between the door body 2 and the kitchen appliance body 1 that allows the user's hand to enter.

[0045] In practical applications, it is also possible to determine whether the distance between the door body 2 and the kitchen appliance body 1 is less than the second preset distance threshold value according to the Hall sensor or micro switch provided on the door body 2. Specifically, the distance between the door body 2 and the kitchen appliance body can be directly detected by the Hall sensor, or the distance between the door body 2 and the kitchen appliance body can be determined by the closing condition of the micro switch. If the micro switch is not closed, that is, the distance between the door body 2 and the kitchen appliance body is greater than or equal to a certain distance, the door closing operation is not performed, otherwise the door closing operation is performed.

[0046] It can be seen from the technical solutions provided by the above embodiments of this specification that a door switch assembly in this specification includes a magnetic part, a moving part and a driving mechanism, the driving mechanism and the moving part are fixedly connected, the magnetic part includes a first magnetic part and a second magnetic part, the first magnetic part and the second magnetic part are correspondingly arranged, and the first magnetic part and the second magnetic part have the same or opposite phases; the driving mechanism drives the moving part to move between an initial position and a target position, in the initial position, the moving part is located between the first magnetic part and the second magnetic part, and when the moving part is located at the target position, there is no obstruction between the first magnetic part and the second magnetic part, thereby improving the stability and reliability of the automatic door opening and closing control, effectively preventing the occurrence of difficulties in opening and closing the door, and thus improving the user experience. In addition, during the process of opening or closing the door, the switch operation of the door body can be controlled according to the distance between the user and the door body, and the distance between the door body and the kitchen appliance body, to ensure the safety and reliability of the automatic door opening and closing control.
