[0039] In order to make the person skilled in the art to which the present application belongs more clearly understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor are within the scope of protection of the present application.

[0040] The dishwasher is a kind of kitchen appliance for automatic cleaning of tableware, which is gradually entering more and more ordinary families. Usually, the dishwasher has a drying function, so that the tableware can be quickly dried after cleaning, to prevent bacteria from breeding in a humid environment.

[0041] Dishwasher is a kind of kitchen appliance for automatic cleaning of tableware, which is gradually entering more and more ordinary families. Generally, the dishwasher has a drying function, so that the tableware can be quickly dried after cleaning to prevent bacteria breeding in a humid environment.

[0042] After the washing program of the dishwasher ends, a higher temperature is required for drying. In order to solve the problem of high energy consumption, in the related art, the door of the dishwasher is automatically opened at a certain angle after the washing program ends, and air exchange is used to dry the tableware in the dishwasher, so as to quickly discharge the hot and humid air in the dishwasher to achieve better drying effect and reduce energy consumption.

[0043] In the related art, the door of the dishwasher is connected to the body through a buffer to ensure the safety of the door opening. If the buffer fails to provide the corresponding pulling force, if the door of the dishwasher is automatically opened at this time, the door will fall rapidly, which may cause hidden dangers, such as injuring users, children or pets. Although the dishwasher can achieve the purpose of drying, it has a high safety risk, which affects the user experience.

[0044] Based on the above technical problems, the present application provides a detection assembly to at least partially avoid the safety risk of falling of the door of the household appliance after opening, so as to improve the safety and user experience. The detection assembly involved in the present application can be applied to household appliances such as dishwashers and other household appliances with openable doors, such as dishwashers, ovens, disinfection cabinets, etc., to prevent safety risks caused by falling of the door. The following will explain the embodiment of the detection assembly applied to the dishwasher.

[0045] Figure 1 The structure of the household appliance in some embodiments is shown, Figure 2 The structure of the base part in Figure 1 is shown. The base part is combined with Figure 1 and Figure 2The detection assembly 10 provided by the present application is suitable for a household appliance, which comprises a door body 100, a machine body 200, and a buffer 300. The machine body 200 is provided with a feeding opening. The door body 100 is connected to the feeding opening of the machine body 200 in a hinged manner. The buffer 300 is connected between the door body 100 and the machine body 200. At least part of the buffer 300 is elastic. The buffer 300 has a first end and a second end. The first end of the buffer 300 is connected to the machine body 200. The second end of the buffer 300 is connected to the door body 100. When the door body 100 moves relative to the machine body 200, the elastic part of the buffer 300 deforms synchronously and moves with the door body 100 to provide a buffer tension to the door body 100 to prevent the door body 100 from falling. If the buffer 300 fails to provide the corresponding tension, if the door body of the dishwasher is automatically opened at this time, the door body will fall rapidly, which may cause hidden dangers.

[0046] In combination Figure 1 and Figure 2 When the household appliance is a dishwasher, the front end of the machine body 200 of the dishwasher is open to form a feeding opening of the dishwasher. The door body 100 can close the feeding opening of the dishwasher to form a sealed space in the dishwasher to run the dishwashing program of the dishwasher.

[0047] In combination Figure 1 and Figure 2 In some embodiments, the side part of the door body 100 is connected to the machine body 200 through a hinge 600. The top part of the door body 100 is connected to an opening door member 700 arranged on the machine body 200. The opening door member 700 can automatically open the door body 100 by a certain angle after the household appliance completes the corresponding program to dry the dishes in the machine body 200 by air exchange, so that the hot and humid air in the dishwasher is quickly discharged to achieve a better drying effect and reduce energy consumption.

[0048] In combination Figure 1 and Figure 2 In some embodiments, the buffer 300 comprises a tension spring 301 and a tension rope 302. The tension spring 301 and the tension rope 302 are connected to connect the door body 100 and the machine body 200. During the opening and closing of the door body 100, the tension spring 301 of the buffer 300 deforms correspondingly to drive the tension rope 302 to move back and forth. In addition, in other embodiments, the tension rope 302 can also have a certain elasticity, and the elastic deformation capacity of the tension rope 302 is smaller than that of the tension spring 301. During the opening and closing of the door body 100, the tension rope 302 also deforms correspondingly.

[0049] In combination Figure 1 and Figure 2In an embodiment, one end of the tension spring 301 is connected to the machine body 200, one end of the pull rope 302 is connected to the other end of the tension spring 301, and the other end of the pull rope 302 is connected to the door body 100, that is, the door body 100 and the machine body 200 are connected by the combination of the tension spring 301 and the pull rope 302. In another embodiment, the tension spring 301 can also be provided in plurality, and the adjacent tension springs 301 are connected by the pull rope 302, so as to connect the door body 100 and the machine body 200 by the combination of the plurality of tension springs 301 and the pull rope 302. During the opening and closing of the door body 100, the plurality of tension springs 301 of the buffer 300 are deformed correspondingly, so as to drive the pull rope 302 to move back and forth.

[0050] In combination Figure 1 And Figure 2 In some embodiments, the bottom of the machine body 200 is provided with a base 201, the inner container of the machine body 200 is arranged above the base 201, and the detection assembly 10 is arranged on the base 201. The base 201 of the present application is provided with a connecting piece 202, which can be a rod structure and is arranged on the side of the base 201 close to the door body 100. The tension spring 301 can be a spring, one end of which is connected to the connecting piece 202, and the other end extends in a horizontal direction away from the connecting piece 202.

[0051] In combination Figure 1 And Figure 2 In some embodiments, the machine body 200 is further provided with a turning piece, and the pull rope 302 passes through the turning piece. During the opening and closing of the door body 100, the reciprocating movement of the pull rope 302 generates a friction force with the turning piece, so as to balance the weight of the door body 100, and adapt to the opening of the door body 100 with greater weight. In addition, the turning and guiding of the turning piece can also keep the pull rope 302 in tension, so that the pull rope 302 can only move on a set track, so as to avoid interference between the pull rope 302 and other parts of the household appliance during movement.

[0052] In combination Figure 1 And Figure 2 In an embodiment, the turning piece can be a wheel structure, which is rotatably connected to the machine body 200. The pull rope 302 and the turning piece form rolling friction. Although the friction between the pull rope 302 and the turning piece is reduced, the pull rope 302 can still move smoothly on the turning piece, reducing the degree of wear of the pull rope 302 and improving the service life of the pull rope 302. In another embodiment, the turning piece can also be fixedly arranged on the machine body 200, and the pull rope 302 and the turning piece form static friction, so as to increase the friction between the pull rope 302 and the turning piece.

[0053] In some embodiments, the door body 100 can be provided with multiple turning pieces. Through the friction between the multiple turning pieces and the pull rope 302, the opening and closing of the door body 100 with different self-weights can be adapted, and the pull rope 302 can be kept in tension, so that the pull rope 302 can only move on a set track to avoid interference between the pull rope 302 and other parts of the dishwasher during movement.

[0054] In combination Figure 3 and Figure 1 In an embodiment, the turning piece of the present application is provided with two, which are a first turning piece 303 and a second turning piece 304. The first turning piece 303 and the second turning piece 304 are both connected to the base 201 of the machine body 200. The first turning piece 303 and the connecting piece 202 are located on both sides of the base 201 of the machine body 200 in the horizontal direction. The second turning piece 304 is connected above the connecting piece 202 and the first turning piece 303. One end of the pull rope 302 is connected to the tension spring 301. The other end of the pull rope 302 is sequentially wound around the first turning piece 303 and the second turning piece 304 and connected to the hinge 600. The pull rope 302 between the hinge 600 and the second turning piece 304 is arranged in an inclined manner. In another embodiment, the other end of the pull rope 302 can also be connected to the side of the door body 100, which is not limited here.

[0055] Figure 4 The assembly diagram of a detection assembly in Figure 3 is shown, Figures 1-4 The structural diagram of another view of Figure 2 is shown. In combination Figure 5 , the detection assembly 10 of the present application is connected to the machine body 200. The detection assembly 10 includes a trigger 400 and a sensing piece 500. The trigger 400 has a first position and a second position. The trigger 400 reciprocates between the first position and the second position. The sensing piece 500 is provided with a sensing part 507. When the trigger 400 is in the first position, the sensing part 507 is separated from the trigger 400. When the trigger 400 is in the second position, the sensing part 507 is triggered by the trigger 400 to generate a trigger signal.

[0056] The detection assembly 10 provided by the application is applied to a household appliance. When the trigger 400 of the detection assembly 10 is in the first position, the trigger 400 of the detection assembly 10 is limited by the buffer 300 in normal working state, and the sensing part 507 of the detection assembly 10 is separated from the trigger. When the buffer is invalid, the trigger 400 moves from the first position to the second position due to the lack of the limitation of the buffer 300. When the trigger 400 is in the second position, the sensing part 507 is triggered by the trigger 400 to generate a trigger signal to confirm whether the buffer 300 is in normal working state, thereby avoiding the safety hazard of the falling door body caused by the opening of the door body under the condition that the buffer 300 is invalid, and improving the safety and user experience. The specific details of the detection assembly 10 are further described with reference to the drawings.

[0057] It should be noted that the first position of the trigger 400 shown in the application refers to the position of the trigger 400 limited by the buffer 300 in the normal working state of the buffer 300, which includes the position of the trigger 400 limited by the buffer 300 when the door body 100 is closed to the machine body 200, and the position of the trigger 400 limited by the buffer 300 when the door body 100 is opened. The second position of the trigger 400 refers to the position of the trigger 400 when the sensing part 507 of the sensing part 500 is triggered by the trigger 400 in the abnormal invalid state of the buffer 300.

[0058] In combination Figure 3 In an embodiment, at least part of the pull rope 302 constituting the buffer 300 is arranged to be inclined. When the trigger 400 is in the first position, the trigger 400 abuts against the inclined part of the pull rope 302. The inclined part of the pull rope 302 constitutes the limiting part of the buffer 300 to limit the trigger 400 to the first position. In addition, the inclined part of the pull rope 302 is connected to the door body 100, so that the trigger 400 can respond in time under the condition that the buffer 300 is invalid. In another embodiment, when the trigger 400 is in the first position, the trigger 400 can also abut against the horizontal part of the pull rope 400, which is not limited in the application.

[0059] Figures 3-5 The structure of the trigger and the sensing part in the detection assembly is shown. Figures 3-5 The structure of the trigger and the sensing part in the detection assembly is shown. Figures 3-5In an embodiment, the detection assembly 10 further comprises a fixing base 401 which can be substantially L-shaped and comprises a first plate 4011 and a second plate 4012 which are integrally formed. The first plate 4011 is vertically arranged and is provided with a mounting hole 4013 for being assembled to the base 201 of the machine body 200 by means of screws or other parts. The second plate 4012 is horizontally arranged and is connected to the top end of the first plate 4011 at one end and extends away from the door body 100 at the other end. In another embodiment, the fixing base 401 can also be in other shapes such as T-shaped, V-shaped, etc. and the present application does not limit this.

[0060] In combination Figure 2 In an embodiment, the trigger 400 and the sensing member 500 are both assembled to the fixing base 401 so that the trigger 400 and the sensing member 500 are integrated to the fixing base 401 and are connected to the machine body 200 by means of the fixing base 401. In another embodiment, one of the trigger 400 and the sensing member 500 can be assembled to the fixing base 401 and the other can be assembled to the machine body 200 and the present application does not limit this.

[0061] In combination Figures 3-5 In some embodiments, the detection assembly 10 further comprises a bearing member 403 which is connected to the bottom end of the first plate 4011 and extends towards the second plate 4012, i.e. the bearing member 403 is inclined to the first plate 4011 and faces the sensing member 500 on the second plate 4012. That is, the bearing member 403 is arranged on the fixing base 401 in an inclined direction so that the bearing member 403 is arranged in an inclined manner relative to the machine body 200, the trigger 400 reciprocates in the inclined direction, and the sensing portion 507 of the sensing member 500 is arranged in the moving direction of the trigger 400 so that the trigger 400 triggers the sensing portion 507 of the sensing member when the trigger 400 is in the second position to make the sensing member generate a trigger signal.

[0062] In combination Figures 3-5 In an embodiment, the inclined direction of the bearing member 403 and the inclined direction of the pull rope 302 are arranged in intersecting manner and can be arranged in perpendicular manner so that the pull rope 302 can provide effective pressing force to the trigger 400 on the bearing member and the trigger 400 can respond in time when the buffer member 300 is disabled. In another embodiment, the included angle between the inclined direction of the bearing member 403 and the inclined direction of the pull rope 302 can also be an acute angle or an obtuse angle and the present application does not limit this.

[0063] In combination Figures 3-5A guide cavity 404 is provided on the carrier 403, and the guide cavity 404 opens toward the position of the sensing member 500. One end of the trigger member 400 is connected to the guide cavity 404, and the other end of the trigger member 400 extends out of the opening and can move back and forth between the first position and the second position.

[0064] Combine Figure 6 The detection assembly 10 further includes an elastic member 406. One end of the trigger member 400 is connected to the guide cavity 404, so that the trigger member 400 can be elastically connected to the guide cavity of the carrier 403. When the buffer member 300 is normal, the pull rope 302 of the buffer member 300 presses on the trigger member 400 to compress the elastic member 406, and the trigger member 400 and the sensing portion 507 of the sensing member are separated. When the buffer member 300 is abnormal or fails, the buffer member 300 cannot apply force to the trigger member 400, and the elastic member 406 recovers its deformation, driving the trigger member 400 to move toward the sensing portion 507 of the sensing member 500. The sensing portion 507 of the sensing member and the trigger portion 402 stop each other, so that the sensing member generates a trigger signal to confirm whether the buffer member 300 is working properly.

[0065] Combine Figure 3 In some embodiments, the elastic member 406 may be a spring, one end of which is connected to the inner wall of the guide cavity 404 opposite the opening, and the other end is connected to one end of the trigger member 400. In a specific implementation, a mounting portion 405 is provided on the inner wall of the guide cavity 404 opposite the opening. The mounting portion 405 includes a mounting protrusion or a mounting recess. One end of the elastic member 406 is connected to the mounting portion 405, and the other end of the elastic member 406 is sleeved on the trigger member 400, thereby achieving an assembled connection between the elastic member 406 in the guide cavity 404 and the trigger member 400.

[0066] Figure 7 Shown Figure 3 A cross-sectional diagram of Figure 6 Shown Figure 7 Schematic diagram of the structure of the trigger member 400. Figure 6 as well as Figure 7In an embodiment, the periphery of the guide cavity 404 is provided with a limiting recess 407 which can be a slot structure or a hole structure, and the periphery of the trigger piece 400 is provided with a limiting protrusion 408 which can be a block structure, and the limiting protrusion 408 is movably connected in the corresponding limiting recess 407. When the trigger piece 400 moves in the guide cavity 404, the limiting protrusion 408 of the trigger piece 400 moves in the corresponding limiting recess 407 to limit the movement displacement of the trigger piece 400, and prevent the trigger piece 400 from escaping from the guide cavity 404 under the condition that the buffer piece 300 fails; in addition, the movement of the limiting protrusion 408 in the corresponding limiting recess 407 can also guide the movement of the trigger piece 400, and prevent the trigger piece 400 from twisting in the guide cavity 404, so as to ensure that the trigger part 402 of the trigger piece 400 moves in the set direction to effectively contact the sensing part 507 of the sensing piece 500 under the condition that the buffer piece 300 fails, avoid the safety hazard of the door body 100 falling due to the failure of the buffer piece 300 to cause the two to fail to contact, and improve the safety and user experience.

[0067] In combination Figure 7 and Figure 5 In an embodiment, the limiting protrusion 408 of the present application is arranged on the periphery of the end of the trigger piece 400 away from the sensing piece 500, and the limiting protrusion 408 and the limiting recess 407 can be correspondingly provided with a plurality of limiting protrusions 408, and the limiting protrusion 408 is movably connected in the corresponding limiting recess 407. In another embodiment, the limiting protrusion 408 can also be arranged at the middle part of the periphery of the trigger piece 400, which is not limited here.

[0068] In combination Figure 7 Since the periphery of the trigger piece 400 is provided with the limiting protrusion 408, in order to facilitate the assembly of the trigger piece 400 in the guide cavity 404, the end of the trigger piece 400 away from the sensing piece 500 is provided with a first cut slot 409 which can extend to the middle part of the trigger piece 400 and is spaced apart a plurality of times, so that the end of the trigger piece 400 away from the sensing piece 500 has elasticity and can be compressed to pass through the opening of the guide cavity 404 and be pushed into the guide cavity 404, and when the guide protrusion of the trigger piece 400 is pushed into the corresponding limiting recess 407, the guide protrusion is embedded in the corresponding limiting recess 407, so that the trigger piece 400 can be assembled in place.

[0069] In combination Figure 5 and Figure 7In some embodiments, the trigger 400 is further provided with an anti-twist member 410 on the circumferential side thereof, and the circumferential side of the guide cavity 404 is provided with an anti-twist recess 411, the anti-twist member 410 and the anti-twist recess 411 are arranged one by one, and the anti-twist member 410 is movably connected in the corresponding anti-twist recess 411. When the trigger 400 moves in the guide cavity 404, the anti-twist member 410 on the trigger 400 moves in the corresponding anti-twist recess 411 to guide the movement of the trigger 400, so as to prevent the trigger 400 from being twisted in the guide cavity 404, so as to ensure that the trigger part 402 of the trigger 400 moves in a set direction to effectively contact the induction part 507 of the induction member 500 under the condition that the buffer 300 fails, so as to avoid the security risk of the door body 100 falling due to the failure of the two to contact, so as to improve the safety and user experience.

[0070] In combination Figure 3 and Figure 4 In some embodiments, the anti-twist member 410 can be a plate-shaped structure which extends along the axial direction of the trigger 400, and the anti-twist recess 411 can extend from the opening of the guide cavity 404 to the inside of the guide cavity 404, so as to facilitate the assembly of the trigger 400 with the anti-twist member 410 in the guide cavity 404. In addition, the anti-twist member 410 and the anti-twist recess 411 can be arranged in plurality to have better anti-twist effect.

[0071] In combination Figure 6 , Figure 7 , Figure 7 and Figure 3 In some embodiments, the trigger 400 further comprises a limiting member 412 which is connected to the trigger 400 and extends in a direction perpendicular to the movement direction of the trigger 400, and the projection of the limiting member 412 falls at least partially outside the opening along the movement direction of the trigger 400. Under the pressing action of the buffer 300, the trigger 400 moves towards the inside of the guide cavity 404, and since the projection of the limiting member 412 falls at least partially outside the opening, the limiting member 412 abuts against the opening of the guide cavity 404 to limit the movement displacement of the trigger 400. Through the cooperation of the limiting recess and the limiting protrusion 408 and the limiting of the limiting member 412, the trigger 400 can only move back and forth in a set direction, so as to prevent the trigger 400 from being pulled out of or deviated from the guide cavity 404.

[0072] In combination Figure 4In an embodiment, the limiting member 412 can be a plate-shaped structure connected to the middle part of the trigger member 400, and a plurality of reinforcing members 413 are connected between the limiting member 412 and the trigger member 400. In addition, the anti-twist member 410 is also connected to the limiting member 412 to reinforce the connection between the limiting member 412 and the trigger member 400. The other end of the elastic member 406 also abuts against the limiting member 412 to limit the elastic member 406.

[0073] In combination Figure 3 , and Figure 4 In some embodiments, the other end of the trigger member 400 is connected with a support wheel 414. When the trigger member 400 is in the first position, the support wheel 414 of the trigger member 400 abuts against the buffer member 300 to serve as a support part 421 of the trigger assembly. The pull rope 302 of the buffer member 300 passes through the support wheel 414, which on one hand holds the trigger member 400, and on the other hand, during the opening and closing of the door body 100, the reciprocating movement of the pull rope 302 also generates friction with the support wheel 414 to balance the weight of the door body 100, which can adapt to the opening of a door body 100 with a larger weight. In addition, the pull rope 302 is supported by the support wheel 414 which has elasticity and is in a compressed state, so that the pull rope 302 can be kept in tension, and the pull rope 302 can only move on a set track to avoid interference with other parts of the dishwasher during movement. In addition, the support wheel 414 is rotatably connected to the trigger member 400 to form rolling friction between the pull rope 302 of the buffer member 300 and the support wheel 414. Although the friction between the pull rope 302 and the support wheel 414 is reduced, the pull rope 302 can move smoothly on the support wheel 414, reducing the degree of wear of the pull rope 302 and improving the service life of the pull rope 302. In another embodiment, the support wheel 414 can be fixedly arranged on the trigger member 400 to form static friction between the pull rope 302 and the support wheel 414 to increase the friction between the pull rope 302 and the turning member.

[0074] In combination Figure 6 , Figure 7 , Figure 7 and Figure 7 The support wheel 414 is connected to the other end of the trigger member 400 through a support shaft 415 to rotatably assemble the support wheel 414 on the trigger member 400. In a specific implementation, a limiting protrusion 416 is arranged on the periphery of the support shaft 415, and the support wheel 414 is connected between the trigger member 400 and the limiting protrusion 416 to limit the displacement of the support wheel 414 through the trigger member 400 and the limiting protrusion 416, so that the support wheel 414 can only rotate on the support shaft 415 between the trigger member 400 and the limiting protrusion 416.

[0075] In combination Figure 3In an embodiment, the limiting protrusions 416 can be arranged on the end of the support shaft 415 away from the trigger member 400, and the limiting protrusions 416 can be a plurality of protruding structures arranged at intervals around the circumference of the support shaft 415. In another embodiment, the limiting protrusions 416 can also be arranged on the middle part of the support shaft 415, and the limiting protrusions 416 can also be a ring structure, which is not limited here.

[0076] In combination Figure 4 Since the limiting protrusions 416 are arranged on the circumferential side of the support shaft 415, in order to facilitate the assembly of the support wheel 414 on the support shaft 415, the end of the support shaft 415 away from the mounting member is provided with a second cut groove 417, which can extend to the middle part of the support shaft 415 and is arranged at intervals. A plurality of second cut grooves 417 are arranged to make the end of the support shaft 415 away from the mounting member elastic to pass through the support wheel 414, so as to facilitate the assembly of the support wheel 414 on the support shaft 415.

[0077] In combination Figure 4 And Figure 8 In an embodiment, the other end of the trigger member 400 is configured as a trigger part 402 of the trigger member 400 and protrudes to support the wheel 414. During the movement of the trigger member 400 from the first position to the second position, the trigger part 402 of the other end of the trigger member 400 can contact the sensing part 507 of the sensing member 500 in advance of the support wheel 414. When the trigger member 400 is in the first position, the trigger part 402 of the trigger member 400 is separated from the sensing part 507. When the trigger member 400 is in the second position, the trigger part 402 abuts against the sensing part 507 to generate a trigger signal. In addition, the support part 421 and the trigger part 402 of the other end of the trigger member 400 are arranged at intervals. Along the movement direction of the trigger member 400, the support part 421 and the sensing part 507 are arranged in sequence and are arranged in sequence. When the trigger member 400 moves from the first position to the second position, the support part 421 of the trigger member 400 can avoid colliding with the sensing part 507 of the sensing member 500.

[0078] In another embodiment, the support part 421 of the trigger member 400 can also be used as the trigger part 402, that is, the support part 421 and the trigger part 402 of the trigger member 400 are the same component. When the trigger member 400 is in the first position, the trigger part 402 of the trigger member 400 abuts against the pull rope 302 of the buffer member 300, and the trigger part 402 and the sensing part 507 are arranged on the two sides of the limiting part of the pull rope 302 of the buffer member 300, respectively. The trigger part 402 of the trigger member 400 is separated from the sensing part 507. When the trigger member 400 is in the second position, the trigger part 402 abuts against the sensing part 507 to generate a trigger signal.

[0079] In combination Figure 5In an embodiment, at least part of the trigger piece 400 has magnetism, for example, at least part of the trigger portion 402 of the trigger piece 400 has magnetism, when the trigger piece 400 is in the first position, the induction portion 507 of the induction piece and the trigger portion 402 are respectively placed on both sides of the buffer piece 300, the induction portion 507 of the induction piece includes two or more metal pieces 501, at least one metal piece 501 is movably arranged; wherein, under the condition that the buffer piece fails, the trigger portion 402 is moved from the first position to the second position, the trigger portion 402 of the trigger piece 400 approaches the induction portion 507 of the induction piece to drive at least one metal piece 501 to move, so that the two or more metal pieces are in contact to generate a trigger signal to confirm whether the buffer piece 300 works normally, thereby avoiding the security risk of the door body 100 falling caused by opening the door body 100 under the condition that the buffer piece 300 fails, to improve safety and user experience, and has good practicability.

[0080] Figure 8 The structure diagram of another perspective of Figure 4 is shown. In combination with Figure 4 In some embodiments, the head portion of the trigger piece 400 is provided with a groove, and a magnet 418 is built in the groove, so that the head portion of the trigger piece 400 has magnetism, so that only the head portion of the trigger piece 400 has magnetism, to avoid the phenomenon that the assembly and use of other parts are affected under the condition that the trigger piece 400 as a whole has magnetism.

[0081] In combination with Figure 3 In some embodiments, the metal piece 501 of the induction piece 500 is provided with two metal pieces 501, the two metal pieces 501 can be arranged at intervals along the moving direction of the trigger portion 402, and at least part of at least one metal piece 501 has elasticity. Under the condition that the buffer piece 300 fails, since at least part of the trigger piece 400 that moves to approach the induction piece 500 has magnetism, the elastic metal piece 501 can be driven to move by magnetism, so that the two metal pieces 501 are in contact to generate a trigger signal to confirm whether the buffer piece 300 works normally, thereby avoiding the security risk of the door body 100 falling caused by opening the door body 100 under the condition that the buffer piece 300 fails, to improve safety and user experience; if the failure of the buffer piece 300 is removed, the trigger piece 400 returns to the initial position, and the elastic metal piece 501 also returns to the initial position.

[0082] In combination with Figure 4In one embodiment, the two metal members 501 of the present application include a first metal member 5011 located near the trigger member 400 and a second metal member 5012 located away from the trigger member 400. Both the first metal member 5011 and the second metal member 5012 are elastic, and one end of each is relatively fixedly connected to the side of the housing 200 via a mounting block 502. If the buffer fails, at least a portion of the trigger member 400 moving toward the sensing member 500 is magnetic. Therefore, the two metal members 501 can be magnetically driven to deform and move toward the trigger member 400, causing the two metal members 501 to contact each other, thereby generating a trigger signal to confirm whether the buffer 300 is functioning properly. In another embodiment, the first metal member 501 is made of a rigid material and is not elastic, so it will not deform or move under the action of the magnetic trigger member 400. The second metal member 5012 is elastic and deforms and moves toward the first metal member 5011 under the action of the magnetic trigger member 400, so that the two metal members 501 come into contact with each other, thereby generating a trigger signal to confirm whether the buffer member 300 is working normally.

[0083] Combine Figure 8 、 Figure 9 as well as Figure 10 In one embodiment, the sensing member 500 of the present application further includes a sensing base 503, which can be integrally formed on the fixing base 401. A mounting cavity 504 is provided in the fixing base 401. The two metal members 501 are both provided on a side of the mounting cavity 504 close to the trigger member 400 via corresponding mounting blocks 502, so that the sensing member 500 and the trigger member 400 are integrated together to facilitate their transportation and assembly. In addition, an opening can be provided on one side of the mounting cavity 504 to facilitate the assembly of the metal members 501 within the mounting cavity 504. In another embodiment, the two metal members 501 can also be fixed to the side of the body 200 via corresponding mounting blocks 502, that is, the sensing member 500 and the trigger member 400 are arranged separately, which is not limited here.

[0084] Figure 9 A structural schematic diagram of the sensing member of another embodiment is shown. In another embodiment, the sensing member 500 can be a micro switch, and a sensing protrusion 506 is provided on the side of the sensing component facing the trigger member 400. The sensing protrusion 506 is configured as a sensing portion 507, so that when the buffer member 300 fails, the trigger member 400 of the trigger member 400 moves toward the sensing protrusion 506 of the sensing member 500, and the trigger member 400 stops at the sensing protrusion 506 of the sensing member 500 to generate a trigger signal to confirm whether the buffer member 300 is working normally.

Figure 10 as well as Figure 9As described above, the inductor 500 of the present application is connected to the fixing base 401, and the inductor 500 can be connected to the fixing base 401 through the buckle 419. In a specific implementation, the buckle 419 can be arranged on the second plate 4012 of the fixing base 401, and the buckle 419 is clamped on the side of the inductor to connect the inductor 500 to the fixing base 401.

The positioning protrusion 420 is inserted into the corresponding positioning recess 505 to position the inductor 500 on the second plate 4012 of the fixing base 401. Then, through the buckle 419 on the second plate 4012 of the fixing base 401, the inductor 500 can be assembled on the fixing base 401.

The trigger 400 contacts the sensing protrusion 506 of the inductor 500 to generate a trigger signal to confirm whether the buffer 300 is working normally.

[0088] It should be noted that the failure of the buffer 300 means that the elastic deformation of the buffer 300 is insufficient, or the buffer 300 is detached, broken, etc. In addition, if it is confirmed that the buffer 300 of the door body anti-falling device is abnormal, the corresponding abnormal code can be displayed on the display part of the household appliance to remind the user and facilitate the maintenance of the after-sales personnel.
