[0034] An embodiment of the present application provides a household appliance. Figure 1 , Figure 2 , Figure 8 and Fig. 9 The household appliance includes a housing 10 , a door 20 and an interlocking structure 30 . The housing 10 includes a cavity 11 and a shell 12 . The cavity 11 includes a receiving cavity 11 a having an opening 11 b . The shell 12 is located outside the cavity 11 .

[0035] The door body 20 is openably and closably disposed at the opening 11 b , and includes a door hook 21 .

[0036] Specifically, the household appliance can be any type of electrical equipment, such as a microwave oven, a pressure cooker or other electrical equipment. For ease of description, the present application takes the household appliance as a microwave oven as an example for description.

[0037] See also Fig. 9 and Fig.10 The interlocking structure 30 is arranged between the cavity 11 and the shell 12. The interlocking structure 30 includes a frame 31, a micro switch assembly 32, a rotating assembly 33 and an elastic member 34. The frame 31 has a first mounting surface 31a close to the shell 12 and a second mounting surface 31b away from the shell 12. The micro switch assembly 32 is arranged on the first mounting surface 31a, the rotating assembly 33 is rotatably arranged on the frame 31, and the elastic member 34 is arranged on the second mounting surface 31b, and is respectively connected to the frame 31 and the rotating assembly 33.

[0038] See also Figures 3 to 6When the door body 20 is closed, the rotating assembly 33 rotates under the push of the door hook 21 until it abuts against the contact of the microswitch assembly 32, so that the microswitch assembly 32 is triggered and the elastic member 34 is in a compressed state or a stretched state; when the door body 20 is opened, the door hook 21 is separated from the rotating assembly 33, and the elastic member 34 is switched to the initial state to reverse and reset the rotating assembly 33 and separate from the microswitch assembly 32.

[0039] Specifically, when the door body 20 is closed, the door hook 21 is locked with the elastic buckle on the housing 10, and the elastic buckle is also connected to the door opening button of the household appliance. The insertion direction of the door hook 21 can be parallel to the plane where the frame 31 is located, and the frame 31 can provide installation support for other structures of the interlocking structure 30 to ensure the positional matching relationship between various components.

[0040] The rotating assembly 33 can rotate relative to the frame 31. When the door body 20 is closed, the door hook 21 contacts the rotating assembly 33 to push the rotating assembly 33 to rotate until it contacts the contact of the micro switch assembly 32. Since the elastic member 34 is connected to the frame 31 and the rotating assembly 33 respectively, the elastic member 34 can be elastically deformed as the rotating assembly 33 rotates, thereby having elastic force.

[0041] The rotating assembly 33 can be an integral structure or a split structure.

[0042] For example, see Figures 3 to 6 The rotating assembly 33 includes an interlocking lever 332 and a cam 333 . The cam 333 is rotatably disposed on the first mounting surface 31 a . The cam 333 is used to trigger the monitoring micro switch 323 and the secondary micro switch 322 . The lever is used to trigger the primary micro switch 321 .

[0043] Correspondingly, the door body 20 has two door hooks 21, which push the interlocking lever 332 and the cam 333 respectively to rotate the interlocking lever 332 and the cam 333 respectively, thereby triggering the monitoring micro switch 323 and the secondary micro switch 322, and triggering the primary micro switch 321.

[0044] The micro switch assembly 32 includes at least one micro switch, that is, one micro switch or multiple micro switches, and the micro switch has contacts that can be triggered when the rotating assembly 33 abuts. The micro switch assembly 32 is disposed on a side of the frame 31 close to the housing 12, which can facilitate subsequent maintenance and replacement.

[0045] For example, see Figures 3 to 7The micro switch assembly 32 includes a primary micro switch 321, a secondary micro switch 322 and a monitoring micro switch 323. When the door body 20 is closed, the rotating assembly 33 triggers the monitoring micro switch 323, the primary micro switch 321 and the secondary micro switch 322 in sequence under the push of the door hook 21. When the door body 20 is opened, the rotating assembly 33 separates from the primary micro switch 321, the secondary micro switch 322 and the monitoring micro switch 323 in sequence.

[0046] Specifically, the primary microswitch 321 is used to control the main circuit of the household appliance, the secondary microswitch 322 is used to control the household appliance door switch detection circuit, and the monitoring microswitch 323 is used to control the switch circuits of the primary microswitch 321 and the secondary microswitch 322.

[0047] The primary micro switch 321 and the secondary micro switch 322 are normally open switches, located in the main circuit of the circuit. After the door body 20 is closed, the switches are turned on, and the household appliance can work safely. The monitoring micro switch 323 is a normally closed switch, located between the primary micro switch 321 and the secondary micro switch 322. When the door body 20 is closed, the monitoring micro switch 323 must be triggered first to disconnect it, and then the primary micro switch 321 and the secondary micro switch 322 must be triggered to close it, and the household appliance works normally at this time. When the door body 20 is opened, the primary micro switch 321 and the secondary micro switch 322 must be reset first to disconnect them, and then the monitoring micro switch 323 must be reset to close them, and the household appliance stops working at this time, otherwise it will cause a short circuit and burn out the fuse.

[0048] In addition, depending on the location and connection method of the elastic member 34, when the door body 20 is closed, the elastic member 34 may be compressed or stretched.

[0049] When the door body 20 is opened, the door hook 21 is separated from the rotating assembly 33. After the rotating assembly 33 loses the abutment of the door hook 21, it rotates in the opposite direction to the closing process of the door body 20 under the elastic force of the elastic member 34, thereby achieving the purpose of resetting. The elastic member 34 also switches to the initial state, where the initial state refers to the state of the elastic member 34 when the door body 20 does not act on the rotating assembly 33. According to the actual design situation, it can be a natural state or have a certain elastic force. In addition, since the rotating assembly 33 is reversed and reset, it is separated from the micro switch assembly 32, so it will not abut the contacts of the micro switch assembly 32, thereby resetting the micro switch assembly 32.

[0050] The elastic member 34 may be various types of springs, or other elastic components that can achieve elastic deformation to provide elastic force, and may be set according to actual conditions.

[0051] For example, see Figure 7 The elastic member 34 is a torsion spring 341, and the torsion spring 341 includes a first connecting leg 342 and a second connecting leg 343. The first connecting leg 342 is connected to the frame 31, and the second connecting leg 343 is connected to the rotating assembly 33. The connection between the second connecting leg 343 and the rotating assembly 33 is misaligned with the rotation center of the rotating assembly 33. Therefore, the torsion spring 341 can generate elastic deformation to provide elastic force when the frame 31 and the rotating assembly 33 are relatively displaced. It is understandable that the second connecting leg 343 should not be connected at the rotation center of the rotating assembly 33 to avoid the torsion spring 341 from being unable to deform.

[0052] For related technologies, see Fig.11 The elastic member 34' is arranged on the side of the frame body close to the outer shell 12'. If the elastic member 34' is close to the outer shell 12', the safety specification requirement is not met. The standard requires that the elastic member 34' should be at least 5mm away from the outer shell 12'. Therefore, the elastic member 34' and the outer shell 12' in the related art are arranged at intervals, which increases the size of the outer shell 12' of the microwave oven, thereby increasing the overall volume of the microwave oven.

[0053] The household appliance of the embodiment of the present application includes a housing 10, a door 20 and an interlocking structure 30. The frame 31 of the interlocking structure 30 has a first mounting surface 31a close to the housing 12 and a second mounting surface 31b away from the housing 12. The micro switch assembly 32 is arranged on the first mounting surface 31a, and the elastic member 34 is arranged on the second mounting surface 31b, and is connected to the frame 31 and the rotating assembly 33 respectively. Therefore, by arranging the elastic member 34 on the second mounting surface 31b away from the housing 12, on the one hand, it is possible to prevent the housing 12 from accidentally touching the elastic member 34 during the installation process, thereby avoiding the failure of the interlocking structure 30 and reducing the maintenance rate of the household appliance. On the other hand, since the elastic member 34 is not arranged on the side of the frame 31 close to the housing 12, it is not necessary to widen the interlocking structure 30 so that the elastic member 34 forms a certain safety distance with the housing 12. The size of the interlocking structure 30 can be reduced while meeting the safety performance, thereby reducing the volume of the household appliance. At the same time, there is no need to solve the safety problem by making the shell 12 protrude to form a convex bump, so the aesthetic appearance can be maintained.

[0054] Another embodiment of the present application provides an interlocking structure 30 , and the interlocking structure 30 is the interlocking structure 30 described in any embodiment of the present application.

[0055] It should be noted that since the elastic member 34 and the micro switch assembly 32 of the interlocking structure 30 are respectively located on different sides of the frame 31, when the interlocking structure 30 is installed on the housing 10 of the household appliance, one side of the micro switch assembly 32 can be facing the side of the outer shell 12 to reduce the volume of the household appliance. It can be seen that the interlocking structure 30 of the present application is small in size and can be used in compact models.

[0056] In one embodiment, please refer to Figure 7 The frame 31 has a through opening 31c, a partial area of ​​the rotating assembly 33 extends into the through opening 31c to form a connecting column 331, the second connecting leg 343 is connected to the connecting column 331, and the connecting column 331 is rotatably disposed in the through opening 31c.

[0057] Specifically, the second connecting leg 343 of the torsion spring 341 is connected to the connecting column 331 extending into the through opening 31 c, so that the torsion spring 341 can be connected even if it is not in the same plane as the rotating assembly 33 .

[0058] It should be noted that the size of the through opening 31 c is larger than the outer size of the connecting column 331 , so that the connecting column 331 can rotate in the through opening 31 c when the rotating assembly 33 rotates.

[0059] The specific shape of the opening 31c is not limited. For example, the opening 31c is an arc-shaped opening 11b.

[0060] In one embodiment, please refer to Figure 5 The frame 31 has a butting port 31d, and the first connecting leg 342 passes through the butting port 31d and butts against the side wall of the butting port 31d. Thus, the first connecting leg 342 can be stably mounted on the frame 31.

[0061] It should be noted that the size of the opening 11b of the abutment port 31d is larger than the outer dimensions of the first connecting leg 342. On the one hand, it can facilitate the first connecting leg 342 to extend into the abutment port 31d. On the other hand, it can also prevent the torsion spring 341 from being too tightly connected to the frame 31 and causing damage to the torsion spring 341 during the extension and retraction process.

[0062] In one embodiment, please refer to Figure 7 A portion of the first mounting surface 31a is recessed to form a first mounting cavity 31aa. The first mounting cavity 31aa has an abutment port 31d connecting the two sides of the frame body 31. The first connecting leg 342 passes through the abutment port 31d to extend into the first mounting cavity 31aa.

[0063] Specifically, since the first connecting leg 342 directly passes through the abutment interface 31d, by forming the first installation cavity 31aa, the area where the first connecting leg 342 passes through the abutment interface 31d can be accommodated in the first installation cavity 31aa, which can prevent the first connecting leg 342 extending out of the abutment interface 31d from damaging the structure on the side of the first installation surface 31a, and can also prevent the user from being scratched during the disassembly and assembly of the interlocking structure 30, thereby reducing safety hazards.

[0064] In one embodiment, please refer to Figure 5 The torsion spring 341 includes a spring coil 344 located between the first connecting leg 342 and the second connecting leg 343. The frame 31 has an abutting groove 31e located on one side of the second mounting surface 31b. The spring coil 344 is located in the abutting groove 31e, and the length of the abutting groove 31e is greater than the outer diameter of the spring coil 344. In this way, the stability of the torsion spring 341 can be greatly improved, and the elastic deformation of the torsion spring 341 can be facilitated.

[0065] Specifically, one end of the first connecting leg 342 is connected to the frame 31, and the other end extends to the spring coil 344. One end of the second connecting leg 343 is connected to the rotating assembly 33, and the other end also extends to the spring coil 344. The number of coils of the spring coil 344 can be set according to actual conditions.

[0066] The specific formation method of the abutting groove 31e is not limited. For example, a part of the second mounting surface 31b is protruded to form a reinforcing rib, and a part of the reinforcing rib is disconnected to form the abutting groove 31e.

[0067] In one embodiment, please refer to Figure 5 A partial area of ​​the second mounting surface 31b is recessed to form a second mounting cavity 31ba, and at least a partial area of ​​the second mounting cavity 31ba on the side close to the primary micro switch 321 is open to form a connecting port 31bb, and the interlocking lever 332 is rotatably arranged in the second mounting cavity 31ba to trigger the primary micro switch 321 through the connecting port 31bb under the push of the door hook 21.

[0068] Specifically, the interlocking lever 332 can be installed in the second mounting cavity 31ba from one side of the second mounting surface 31b. Under the push of the door hook 21, the interlocking lever 332 can rotate in the second mounting surface 31b. Since the second mounting cavity 31ba has a connecting port 31bb open to the side of the primary microswitch 321, the interlocking lever 332 rotates to the connecting port 31bb to abut against the contacts of the primary microswitch 321, thereby triggering the primary microswitch 321.

[0069] It is understandable that when the door body 20 is opened, the door hook 21 is separated from the interlocking lever 332, and the interlocking lever 332 can also rotate and reset, thereby separating from the primary micro switch 321, so that the primary micro switch 321 is reset.
