[0049] In order to make the 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 described clearly and completely 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, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0050] A dishwasher is a kind of kitchen appliance for automatically washing 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 washing, to prevent bacteria from breeding in a humid environment.

[0051] A dishwasher is a kind of kitchen appliance for automatically washing 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 washing, to prevent bacteria from breeding in a humid environment.

[0052] After the washing program of the dishwasher ends, a higher temperature is needed for drying. In order to solve the problem of high energy consumption, in the related art, the door body of the dishwasher is automatically opened to a certain angle after the washing program ends, air exchange is used to realize drying treatment of the tableware inside the machine body, to quickly discharge the hot and humid air inside the dishwasher, to achieve better drying effect and reduce energy consumption.

[0053] In the related art, the door body of the dishwasher is connected to the machine body through a buffer to ensure the safety of the opening of the door body. If the buffer fails to provide the corresponding pulling force, if the door body of the dishwasher is automatically opened at this time, the door body will rapidly fall, which will cause hidden dangers, and there is a risk of injuring users, children or pets. Although the dishwasher can achieve the purpose of drying, there is a high safety risk, which affects the user experience.

[0054] Based on the above technical problems, the present application provides a detection assembly to at least partially avoid the safety risk of falling after the door body of the household appliance is opened, to improve 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 and closable door bodies, such as dishwashers, ovens, sterilizers, etc., to prevent safety risks caused by falling of the door body. The following will explain the embodiment of the detection assembly applied to the dishwasher.

[0055] 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. In combination with Figure 1 and Figure 2 , the detection assembly 10 provided by the present application is suitable for a household appliance, which includes a door body 100, a machine body 200 and a buffer 300. The machine body 200 is provided with a drop port, the door body 100 is openably and closably connected to the drop port of the machine body 200, the buffer 300 is connected between the door body 100 and the machine body 200, at least part of the buffer 300 has elasticity, 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, and 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 pulling force to the door body 100 to prevent the door body 100 from falling. If the buffer 300 fails to provide the corresponding pulling force, if the door body of the dishwasher is automatically opened at this time, the door body will rapidly fall, which will cause hidden dangers.

[0056] In combination with 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 drop port of the dishwasher, and the door body 100 can close the drop port of the dishwasher to form a sealed space inside the dishwasher to run the washing program of the dishwasher on the tableware.

[0057] In combination with Figure 1 and Figure 2In some embodiments, the side of the door body 100 is connected to the machine body 200 through the hinge 600, and the top of the door body 100 is connected to the door opening member 700 arranged on the machine body 200. The door opening member 700 can automatically open the door body 100 by a certain angle after the household appliance finishes the corresponding program, and utilize air exchange to realize drying treatment of the tableware in the machine body 200, so as to quickly discharge the hot and humid air in the dishwasher, so as to achieve better drying effect and reduce energy consumption.

[0058] In combination Figure 1 and Figure 2 In some embodiments, the buffer member 300 includes a tension spring 301 and a tension rope 302, which 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 member 300 deforms correspondingly to drive the tension rope 302 to move reciprocally. 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 less than that of the tension spring 301. During the opening and closing of the door body 100, the tension rope 302 also deforms correspondingly.

[0059] In combination Figure 1 and Figure 2 In an embodiment, one end of the tension spring 301 is connected to the machine body 200, one end of the tension rope 302 is connected to the other end of the tension spring 301, and the other end of the tension rope 302 is connected to the door body 100, that is, the door body 100 and the machine body 200 are connected through the combination of one tension spring 301 and one tension rope 302. In another embodiment, the tension spring 301 can also be provided in plurality, and adjacent tension springs 301 are connected through the tension rope 302, so as to connect the door body 100 and the machine body 200 through the combination of the plurality of tension springs 301 and the tension rope 302. During the opening and closing of the door body 100, the plurality of tension springs 301 of the buffer member 300 deforms correspondingly to drive the tension rope 302 to move reciprocally.

[0060] In combination Figure 1 and Figure 2 In some embodiments, the bottom of the machine body 200 is provided with a base 201, and the inner container of the machine body 200 is arranged above the base 201. A connecting member 202 is arranged on the base 201, 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 member 202, and the other end extends in a horizontal direction away from the connecting member 202.

[0061] In combination Figure 1 and Figure 2In some embodiments, the body 200 is further provided with a turning member, and the pull rope 302 passes through the turning member. 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 member, so as to balance the weight of the door body 100, and to adapt to the opening of the door body 100 with a larger weight. In addition, the turning member can guide the turning of the pull rope 302, so that the pull rope 302 is kept in tension, and the pull rope 302 can only move on a set track, so as to avoid the interference between the pull rope 302 and other parts of the household appliance during the movement.

[0062] In combination Figure 1 and Figure 2 In an embodiment, the turning member can be a wheel structure, which is rotatably connected to the body 200. The pull rope 302 and the turning member form a rolling friction. Although the friction between the pull rope 302 and the turning member is reduced, the pull rope 302 can still move smoothly on the turning member, the wear degree of the pull rope 302 is reduced, and the service life of the pull rope 302 is improved. In another embodiment, the turning member can be fixedly arranged on the body 200, and the pull rope 302 and the turning member form a static friction, so as to increase the friction between the pull rope 302 and the turning member.

[0063] In some embodiments, the turning member can be provided with a plurality of turning members. The friction between the plurality of turning members and the pull rope 302 can adapt to the opening and closing of the door body 100 with different weights, and keep the pull rope 302 in tension, so that the pull rope 302 can only move on a set track, so as to avoid the interference between the pull rope 302 and other parts of the dishwasher during the movement.

[0064] In combination Figure 1 and Figure 2 In an embodiment, the turning member of the present application is provided with two turning members, i.e. a first turning member 303 and a second turning member 304. The first turning member 303 and the second turning member 304 are both connected to the base 201 of the body 200. The first turning member 303 and the connecting member 202 are located on the two sides of the base 201 of the body 200 in the horizontal direction. The second turning member 304 is connected above the connecting member 202 and the first turning member 303. One end of the pull rope 302 is connected to the tension spring 301. The other end of the pull rope 302 passes through the first turning member 303 and the second turning member 304 in sequence, and is connected to the hinge 600. The pull rope 302 between the hinge 600 and the second turning member 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 herein.

[0065] Figure 3 A schematic assembly view of a detection assembly is shown in Figure 1 A schematic structural view of another view of Figure 4 A schematic structural view of another view of Figure 3 In combinationFigures 1-4 The detection assembly 10 of the present application is connected to the body 200, and the detection assembly 10 comprises a trigger 400 and a sensing member 500. The trigger 400 has a first position and a second position, and reciprocally moves between the first position and the second position. The sensing member 500 is provided with a sensing portion 507. When the trigger 400 is in the first position, the sensing portion 507 is separated from the trigger 400. When the trigger 400 is in the second position, the sensing portion 507 is triggered by the trigger 400 to generate a trigger signal.

[0066] 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 which is in normal working state. The sensing portion 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 limitation of the buffer 300. When the trigger 400 is in the second position, the sensing portion 507 is triggered by the trigger 400 to generate a trigger signal, so as to confirm whether the buffer 300 is in normal working state, thereby avoiding the safety hazard of falling of the door body caused by opening 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 by means of the drawings.

[0067] It should be noted that the first position of the trigger 400 shown in the present application refers to the position of the trigger 400 limited by the buffer 300 under the condition that the buffer 300 is in normal working state, which includes the position of the trigger 400 limited by the buffer 300 when the door body 100 is closed to the 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 portion 507 of the sensing member 500 is triggered by the trigger 400 under the condition that the buffer 300 is in abnormal invalid state.

[0068] In combination Figure 2 In an embodiment, at least part of the pull rope 302 constituting the buffer 300 is obliquely arranged. When the trigger 400 is in the first position, the trigger 400 abuts against the inclined portion of the pull rope 302. The inclined portion of the pull rope 302 constitutes a limiting portion of the buffer 300, so as to limit the trigger 400 to the first position. In addition, the inclined portion 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 portion of the pull rope 400, which is not limited in the present application.

In another embodiment, one of the trigger 400 and the sensing part 500 can be assembled on the fixing seat 401, and the other can be assembled on the machine body 200, which is not limited in the present application.

[0071] The detection assembly is shown Figures 3-5 In some embodiments, the detection assembly 10 further comprises a bearing part 403 connected to the bottom end of the first plate 4011 and extending towards the second plate 4012, i.e. the bearing part 403 is inclined to the first plate 4011 and towards the sensing part 500 on the second plate 4012. That is, the bearing part 403 is arranged on the fixing seat 401 in an inclined direction, so that the bearing part 403 is arranged inclined to the machine body 200, the trigger 400 reciprocates in the inclined direction, and the sensing part 500 is arranged in the moving direction of the trigger 400, so that when the trigger 400 is in the second position, the trigger 400 triggers the sensing part 500 to generate a trigger signal.

[0072] The detection assembly is shown Figure 2 In an embodiment, the inclined direction of the bearing part 403 and the inclined direction of the pull rope 302 are arranged intersecting each other, and can be arranged perpendicular to each other, so that the pull rope 302 can provide effective pressing force to the trigger 400 on the bearing part, and the trigger 400 can respond in time when the buffer part 300 fails. In another embodiment, the included angle between the inclined direction of the bearing part 403 and the inclined direction of the pull rope 302 can also be an acute angle or an obtuse angle, which is not limited in the present application.

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 contact each other, and improve the safety and user experience.

[0077] In combination Figure 6 In combination Figure 7 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 on the middle part of the periphery of the trigger piece 400, which is not limited here.

[0078] 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.

[0079] In combination Figure 5 In combination 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.

[0080] In combination Figure 5 and Figure 7 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.

[0081] In combination Figure 3 , Figure 4 , Figure 6 and Figure 7 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.

[0082] In combination Figure 7In 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.

[0083] In combination Figure 3 In combination 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, so that the door body 100 with a larger weight can be opened. 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.

[0084] In combination Figure 3 In combination Figure 4 In combination Figure 6 In combination 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.

[0085] In combination Figure 7In 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.

[0086] In combination Figure 7 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.

[0087] In combination Figure 3 And Figure 4 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 with a positional deviation. When the trigger member 400 moves from the first position to the second position, the support part 421 of the trigger member 400 can be prevented from colliding with the sensing part 507 of the sensing member 500.

[0088] 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.

[0089] In combination Figure 4In 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.

In combination with Figure 8 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, so as 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.

[0091] In combination with Figure 4 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.

[0092] In combination with Figure 4In an embodiment, the two metal pieces 501 of the present application include a first metal piece 5011 close to the trigger 400 and a second metal piece 5012 away from the trigger 400, wherein the first metal piece 5011 and the second metal piece 5012 are both elastic, and one end of each is fixedly connected to the side of the body 200 through the mounting block 502. In the case of invalidation of the buffer 300, since at least part of the trigger 400 moving close to the sensing piece 500 is magnetic, the two metal pieces 501 can be driven to deform and move in the direction of the trigger 400 to make the two metal pieces 501 contact each other to generate a trigger signal to confirm whether the buffer 300 is working normally. In another embodiment, the first metal piece 5011 is made of rigid material and does not have elasticity, and will not deform and move under the action of the magnetic trigger 400. The second metal piece 5012 has elasticity and deforms and moves in the direction of the first metal piece 5011 under the action of the magnetic trigger 400 to make the two metal pieces 501 contact each other to generate a trigger signal to confirm whether the buffer 300 is working normally.

[0093] In combination Figure 3 , Figure 4 and Figure 8 , in an embodiment, the sensing piece 500 of the present application further includes a sensing seat 503 which can be integrally formed on the fixing seat 401, and the fixing seat 401 is provided with a mounting cavity 504, and the two metal pieces 501 are arranged on one side of the mounting cavity 504 close to the trigger 400 through the corresponding mounting blocks 502, so that the sensing piece 500 and the trigger 400 are integrated together to facilitate their transportation and assembly. In addition, one side of the mounting cavity 504 can be provided with an opening to facilitate the assembly of the metal piece 501 inside the mounting cavity 504. In another embodiment, the two metal pieces 501 can also be fixed on the side of the body 200 through the corresponding mounting blocks 502, that is, the sensing piece 500 and the trigger 400 are arranged separately, which is not limited here.

In another embodiment, the sensing piece 500 can be a microswitch, and the side of the sensing assembly facing the trigger 400 is provided with a sensing protrusion 506 which is configured as a sensing part 507. In the case of invalidation of the buffer 300, the trigger 400 moves in the direction of the sensing protrusion 506 of the sensing piece 500, and the trigger 400 abuts against the sensing protrusion 506 of the sensing piece 500 to generate a trigger signal to confirm whether the buffer 300 is working normally.

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.

[0097] In combination Figure 9 And Figure 10 The inductor 500 of the present application can be a micro switch. The inductor 500 is provided with a sensing protrusion 506 on the side facing the trigger 400. The sensing protrusion 506 is configured as a sensing part 507. When the buffer 300 fails, the trigger 400 moves in the direction of the sensing protrusion 506 of the inductor 500. 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.

[0098] 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.

When any one of the door body anti-falling devices has an abnormal condition, the household appliance control does not automatically open the door, and the alarm device reminds the user to pay attention. The user can contact the after-sales personnel to maintain the household appliance, so as to prevent the safety technical problem caused by the abnormal opening of the door body 100.

Figure 16 and the accompanying drawings Figure 15 The specific details of the combination of the driving member 1000 and the above-mentioned detection assembly 10 are described below with reference to the accompanying drawings.

[0108] The combination of the driving member 1000 and the above-mentioned detection assembly 10 is described below with reference to the accompanying drawings. Figure 16And Figure 15 The driving member 1000 is connected with the trigger member 400 of the detection assembly 10. Since the trigger member 400 is telescopically connected with the body 200, correspondingly, the driving member 1000 is also telescopically connected with the body 200. The trigger member 400 is limited by the limiting part of the buffer member 300, so that the driving member 1000 is located at the first position. When the buffer member 300 is disabled, the trigger member 400 and the driving member 1000 move synchronously, so that the driving member 1000 moves to the second position.

[0109] In combination Figure 16 And Figure 15 The driving member 1000 protrudes from the trigger member 400. The extension direction of the driving member 1000 is different from the extension direction of the trigger member 400, that is, the driving member 1000 and the trigger member 400 are arranged at an angle. The angle between the driving member 1000 and the trigger member 400 can be an acute angle. When the buffer member 300 is disabled, the driving member 1000 moves from the first position to the second position. The driving member 1000 is not misaligned with the sensing member 500 of the detection assembly 10, so as to avoid the contact and collision between the driving member 1000 and the sensing member 500, and to ensure the normal operation of the driving member 1000 and the sensing member 500.

One end of the driving member 1000 can be integrally connected to the side of the other end of the trigger member 400 and extend to the direction of the transmission member 800, so that the other end of the driving member 1000 protrudes from the trigger member. The driving member 1000 can be arranged vertically. When the driving member 1000 moves from the first position to the second position, the driving member 1000 moves along the arrangement direction of the bearing member 403 of the detection assembly 10.

The first end of the transmission member 800 can abut against or separate from the driving member 1000, and the second end of the transmission member 800 can detachably support the locking member 900. That is, when the driving member 1000 is in the first position, the transmission member 800 is separated from the driving member 1000. When the driving member 1000 is in the second position, the driving member 1000 abuts against the transmission member 800 to drive the transmission member 800 to rotate, and the locking member 900 separates from the transmission member 800 and falls onto the locking portion 601 on the hinge 600 to prevent the door body 100 from opening. In another embodiment, the transmission member 800 may also be rotatably connected to the driving member 1000, that is, when the driving member 1000 is in the first position, the transmission member 800 and the driving member 1000 do not move relative to each other, and the transmission member 800 remains stationary relative to the body 200. When the driving member 1000 is in the second position, the driving member 1000 drives the transmission member 800 to rotate, and the locking member 900 separates from the transmission member 800 and falls onto the locking portion 601 on the hinge 600 to prevent the door body 100 from opening.

[0112] Combine Figure 17 A rotating shaft 204 is provided on the side of the body 200, and the rotating shaft 204 is arranged above the trigger assembly 400. The transmission member 800 is rotatably connected to the rotating shaft 204 so that the transmission member 800 can rotate around the rotating shaft 204 under the drive of the driving member 1000.

When the buffer member 300 fails, the driving member 1000 moves upward to the second position to abut against the second plate 802, thereby driving the first plate of the transmission member 800 to rotate about the rotation axis 204, causing the locking member 900 to disengage from the first plate 801 and fall onto the locking portion 601 of the hinge 600, thereby preventing the door 100 from opening.

[0115] Combine Figure 17In an embodiment, the transmission member 800 further comprises a third plate body 803, which is arranged on the two sides of the second plate body 802 respectively, and the third plate body 803 and the first plate body 801 are arranged in parallel or close to parallel, so that the transmission member 800 is approximately in the shape of a "Y". The second plate body 802 of the transmission member 800 can be in abutment with the driving member 1000 in the second position through the third plate body 803, so that the transmission member 800 is driven to rotate relative to the body 200 under the driving of the driving member 1000.

[0116] In combination Figure 17 In an embodiment, the body 200 is further fixedly connected with an abutment member 205, which is arranged below at least part of the transmission member 800. The abutment member 205 between the transmission member 800 and the body 200 is connected with a second elastic member 804. When the driving member 1000 is in the first position, the second elastic member 804 is in a natural deformation state. When the driving member 1000 is in the second position, the driving member 1000 drives the transmission member 800 to rotate around the rotation shaft 204, and the transmission member 800 compresses the second elastic member 804. At the same time, the locking member 900 is separated from the first plate body 801 and falls into the locking portion 601 of the hinge 600, so as to prevent the door body 100 from being opened. In a specific implementation, the bottom end of the second elastic member 804 is connected to the top of the abutment member 205, and the top end of the second elastic member is connected to the bottom of the first plate body of the transmission member 800. In another embodiment, the abutment member 205 can be arranged above the transmission member. When the driving member 1000 drives the transmission member 800 to rotate around the rotation shaft 204, the transmission member 800 stretches the second elastic member 804, which is not limited in the present application.

[0117] In combination Figure 17 The side of the body 200 is further provided with a guide portion 203, which extends upward from the locking portion 601 of the hinge 600. Under the condition that the locking member 900 is separated from the driving member 1000, the locking member 900 can move to the locking portion 601 along the guide portion 203 by gravity, so as to prevent the door body 100 from being opened. In an embodiment, the guide portion 203 is arranged in a vertical direction. In another embodiment, the guide portion 203 can also be arranged in an inclined manner, which is not limited in the present application.

[0118] In combination Figure 17 In an embodiment, the side of the body 200 can also be provided with a guide hole, which can be arranged in a vertical direction or close to a vertical direction. The guide hole can be a waist-shaped hole. When the driving member 1000 is in the first position, part of the locking member 900 is in the guide hole, and another part of the locking member 900 is outside the guide hole, so as to be supported by the other end of the transmission member 800. The guide hole can be configured as the guide portion 203. In another embodiment, the side of the body 200 is provided with a guide groove, which is configured as the guide portion 203.

[0119] In combination ​ In some embodiments, the lock 900 is provided with a anti-disengagement member 901 at both ends, at least part of the projection of the anti-disengagement member 901 along the length direction of the lock 900 is located outside the guide portion 203. In specific implementation, the lock 900 can be a rod-shaped structure, the lock 900 is movably arranged in the guide portion 203, the anti-disengagement member 901 is a circular structure, which can be integrally formed at the end of the lock 900 and located outside the guide portion 203, the lock 900 can prevent the lock 900 from disengaging from the guide hole during the movement of the lock 900 in the guide portion 203, so that the lock 900 moves in the set direction and falls into the locking portion 601 of the hinge 600.

[0120] It should be noted that in another embodiment, the driving member 1000 of the present application can also be combined with the detection assembly 10 described above, that is, the household appliance only includes the driving member 1000 which can reciprocate between the first position and the second position, the driving member 1000 is limited by the limiting portion of the buffer 300 when the driving member 1000 is in the first position, when the buffer 300 fails, the driving member 1000 moves to the second position, the driving member 1000 drives the transmission member 800 to rotate, the lock 900 separates from the transmission member 800 and falls into the locking portion 601 on the hinge 600 to prevent the opening of the door body 100. In specific implementation, only the sensing member 500 of the detection assembly 10 described above needs to be removed and the trigger member 400 is used as the driving member 1000, which will not be described here.

[0121] The electric appliance of the present application can automatically control the opening of the door body after the failure of the buffer 300 through the linkage of the driving member and the transmission member, thereby avoiding the safety hazard of falling after the opening of the door body of the household appliance, and improving the safety and user experience.
