[0053] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0054] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this invention will not be described separately.

[0055] In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0056] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0057] This invention provides a door lock device that can be applied to cooking equipment such as ovens and fryers, as well as cleaning equipment such as dishwashers and sterilizers. It should be noted that the application scenarios of this invention do not limit the door lock device itself.

[0058] Combination Figures 1-3 As shown below, the implementation of existing door lock devices in cooking equipment is described:

[0059] like Figure 1 The cooking equipment includes a housing 11 and a door 10. The housing 11 includes an inner liner 111 and a fixing frame assembly 112. The inner liner 111 has a cavity 12 for accommodating food to be cooked. The fixing frame assembly 112 is positioned above the door 10 and the inner liner 111. A door lock device 13 is located on the upper surface of the inner liner 111. The door lock device 13 partially passes through the fixing frame assembly 112 and engages with a limiting groove 133 on the door 10 to lock the door. Figure 2 As shown, the relevant door lock device 13 includes a relevant drive member 131 and a relevant movable component 132. The relevant drive member 131 can drive the relevant movable component 132 to rotate, so that the relevant movable component 132 extends into the relevant limiting groove 133 to lock the relevant door body 10, or so that the relevant movable component 132 disengages from the relevant limiting groove 133 to unlock the relevant door body 10. Figure 3The diagram shows the locked state of the door lock device 13 and the door 10. The driving component 131 is fixed to the upper surface of the inner liner 111. The driving component 131 drives the movable component 132 through the fixed frame assembly 112 and into the limiting groove 133 in the door 10. In the prior art, there is an assembly gap between the inner liner 111 and the fixed frame assembly 112, and also between the fixed frame assembly 112 and the door 10. This results in a large assembly gap between the inner liner 111 and the door 10, leading to a large cumulative assembly tolerance. This makes it difficult for the movable component 132 to pass through the fixed frame assembly 112 and into the limiting groove 133 of the door 10. This can cause the door lock device to fail to lock the door, or the movable component 132 to fit too tightly into the limiting groove 133, causing the door lock device to jam. This results in low assembly efficiency of the door lock device and poor reliability of the cooking equipment.

[0060] To address this, embodiments of the present invention provide a door lock device 2, combined with Figure 4 and Figure 5 As shown, the door lock device 2 includes a fixing member 3, a movable component 4, and a resilient member 5. Figure 4 As shown, the fastener 3 provides support for the door lock device 2, and the fastener 3 can be used to install the fixing frame assembly 83 in the cooking equipment (see reference). Figure 14 In this process, the door lock device 2 is fixed to the housing 8. For example... Figure 4 As shown, the movable component 4 is connected to the fixing member 3. It should be noted that this embodiment of the invention does not limit the specific connection method between the movable component 4 and the fixing member 3. The connection method can be a clamp connection, insertion, snap-fit ​​connection, mortise and tenon connection, or adhesive connection, etc.; wherein, at least a portion of the movable component 4 can be positioned relative to the fixing member 3 along a first direction (positive direction). Figure 4 The direction indicated by the middle arrow is translation. It should be noted that translation refers to parallel movement. During the translation, the straight line connecting any two points on the movable part of component 4 remains parallel, and the velocity and acceleration of all points on this movable part of the component are the same. The negative direction of the first direction is... Figure 4 The direction opposite to the arrow. Part of Activity Component 4 (see reference). Figure 5 The thermal element 41 shown can be fixed relative to the fixing member 3, and the other part of the movable component 4 (see reference) Figure 5 The sliding component 42 shown can move relative to the fixed component 3, and the movable component 4 (see reference) Figure 5 The sliding member 42 shown translates relative to the fixed member 3 in the first direction in a positive direction, causing part of the movable component 4 ( Figure 5 The portion of the slider 42 shown extends into the locking groove 6 (in conjunction with...) Figure 14(as shown). In this embodiment of the invention, the movable component 4 extends into the limiting groove 6, thereby locking the movable component 4 with the limiting groove 6. The limiting groove 6 is located in the door body 9 (see reference). Figure 14 In the case shown, the movable component 4 can restrict the movement of the door 9 relative to the box 8, thereby achieving the locking of the door.

[0061] It should be noted that the embodiments of the present invention do not limit the implementation of the translation of the movable component 4 in the first direction. For example, at least part of the movable component 4 can be driven to translate relative to the fixed part by a driving device, or the relative position of the movable component in the first direction can be changed by controlling the temperature of the thermal expansion element. The embodiments of the present invention include, but are not limited to, the above-listed embodiments, as long as the translation of at least part of the movable component 4 in the first direction can be achieved.

[0062] like Figure 5 As shown, the elastic element 5 is disposed between the fixed element 3 and the movable component 4. During the forward translation of the movable component 4 in the first direction, the movable component 4 compresses the elastic element 5, causing the elastic element 5 to undergo elastic deformation. After the compressive force of the movable component 4 disappears, the elastic element 5 can recover its elastic deformation and apply the recovery force to the movable component 4, so that the elastic element 5 can drive the movable component 4 to move in the opposite direction in the first direction. Figure 5 (In the opposite direction of the arrow) the movable component 4 moves away from the door, thereby allowing the movable component 4 to disengage from the limiting groove 6, thus unlocking the door.

[0063] This invention provides a door lock device comprising a fixed member, a movable component, and an elastic component. The movable component is connected to the fixed member and at least a portion of the movable component is capable of translational movement relative to the fixed member in a first direction to extend into a locking groove. The elastic component is disposed between the fixed member and the movable component and can drive the movable component to translate in the opposite direction in the first direction to disengage from the locking groove. This invention simplifies the movement of the door lock device by allowing at least a portion of the movable component to translate relative to the fixed member. The reciprocating translational movement of the movable component in the first direction enables locking and unlocking of the door lock device with the locking groove, reducing the structural volume of the door lock device, lowering the installation difficulty, improving assembly efficiency and reliability, and ultimately enhancing the safety of the cooking equipment.

[0064] In some embodiments, combined with Figure 4 and Figure 5 As shown, when energized, the movable component 4 can move relative to the fixed component 3 in the first positive direction ( Figure 4 (In the direction indicated by the arrow) translation, the movable component can move in the opposite direction relative to the fixed component 3 in the first direction when the power is off. Figure 4(The direction of the arrow shown is opposite) translation. This energized state can be consistent with the energized state of the cooking equipment set by the door lock device. For example, when the cooking equipment is energized, the door lock device is also energized, and the corresponding movable component 4 protrudes into the limiting groove in this state, locking the door of the cooking equipment. When the cooking equipment is de-energized, the door lock device is also de-energized, and the corresponding movable component 4 disengages from the limiting groove in this state, unlocking the door of the cooking equipment. In some embodiments, the energized state of the movable component can be consistent with the temperature state of the cooking equipment. For example, when the temperature of the cooking equipment is greater than or equal to a set value, the movable component is energized, or when the temperature of the cooking equipment is less than the set value, the movable component is de-energized. By controlling the energized and de-energized states of the movable component through temperature control, it is possible to lock the cooking equipment in high-temperature environments and unlock it in low-temperature environments, improving the reliability of the door lock device and enhancing the safety of the cooking equipment.

[0065] In some embodiments, such as Figure 5 As shown, the movable component 4 includes a thermistor 41 and a slider 42. Thermistor 41 is connected to the fixing member 3, and at least a portion of the thermistor 41 remains stationary relative to the fixing member 3, while at least a portion of the thermistor 41 is movable relative to the fixing member 3. At least a portion of the thermistor 41 can move forward in a first direction when the temperature rises and move backward in the first direction when the temperature falls. Specifically, the thermistor 41 represents a temperature-sensitive component, and the thermistor 41 can be configured as a thermal expansion device. When the temperature rises, the material inside the thermistor 41 expands and pushes out of the slider 42 in the first direction; when the temperature falls, the material inside the thermistor 41 contracts. The sliding member 42 extends along the first direction and passes through the fixing member 3. One end of the sliding member 42 abuts against the thermal element 41 in the first direction, and the other end protrudes from the fixing member 3 in the first direction. The opposite ends of the elastic member 5 abut against the sliding member 42 and the fixing member 3 respectively. When the temperature rises, the thermal element 41 expands due to heat and drives the sliding member 42 to move in the positive direction of the first direction toward the limiting groove. The thermal element 41 continuously presses against the sliding member 42, causing the sliding member 42 to continuously compress the elastic member 5 until the sliding member 42 extends into the limiting groove, thereby locking the door. When the temperature drops, the thermal element 41 contracts due to cold and moves in the negative direction of the first direction away from the limiting groove. The pressure force on the elastic member 5 decreases, and the restoring force of the elastic member 5 drives the sliding member 42 to move in the opposite direction of the first direction, moving the sliding member 42 away from the limiting groove until the sliding member 42 completely disengages from the limiting groove, thereby unlocking the door.

[0066] This invention, through its embodiment, sets the movable components as a thermal element and a sliding member. The thermal element, through the principle of thermal expansion, enables the sliding member to translate in the first direction, thereby locking the door lock device with the limiting groove. When the temperature decreases, the restoring force of the elastic member can drive the sliding member to move in the opposite direction in the first direction, thereby unlocking the door lock device with the limiting groove. The movement method is simple and the structure is compact, which helps to reduce the difficulty of installing the door lock device, improve the assembly efficiency of the door lock device, and improve the reliability of the door lock device assembly.

[0067] In some embodiments, such as Figure 6 As shown, the fastener 3 is in the first direction ( Figure 6 A first mounting cavity 31 and a second mounting cavity 32 are sequentially provided in the x-direction shown. The first mounting cavity 31 and the second mounting cavity 32 are not completely enclosed cavities; for example, they can be semi-enclosed cavities. A thermal element 41 can be disposed within the first mounting cavity 31, and a sliding member 42 can be disposed within the second mounting cavity 32. Figure 7 As shown, the fastener 3 also includes a first through hole 33 connecting the first mounting cavity 31 and the second mounting cavity 32, and a second through hole 34 connecting the second mounting cavity 32 with the outside, combined with Figure 6 As shown, the thermal element 41 can at least partially extend through the first through hole 33 into the second mounting cavity 32. For example, in the case of material expansion in the thermal element 41, the thermal element 41 can partially extend through the first through hole 33 into the second mounting cavity 32. The thermal element 41 passing through the first through hole 33 abuts against the slider 42 and drives the slider 42 to move in the positive direction along the first direction. The slider 42 is partially disposed in the second mounting cavity 32, and another part of the slider 42 passes through the second through hole 34 and is located outside the second mounting cavity 32. The other part of the slider 42 can move towards the limiting groove. The slider 42 can translate relative to the second through hole 34 in the first direction, and the second through hole 34 can limit the circumferential movement of the slider 42.

[0068] In this embodiment of the invention, a first mounting cavity and a second mounting cavity are sequentially arranged in a first direction for the fixing member. A thermal element is disposed in the first mounting cavity, and a sliding member is at least partially disposed in the second mounting cavity. When the thermal element located in the first mounting cavity expands thermally, it passes through the first through hole and drives the sliding member to translate in the positive direction along the first direction. When the temperature decreases, the restoring force of the elastic member drives the sliding member to translate in the opposite direction along the first direction. The structure is compact, and the movement direction is simple and reliable. This helps to reduce the installation difficulty of the door lock device, improve the assembly efficiency of the door lock device, and improve the assembly reliability of the door lock device.

[0069] In some embodiments, such as Figure 8As shown, the fixing member 3 also includes a plurality of first snap-fit ​​members 35, which can be symmetrically arranged on both sides of the thermal element 41, and the plurality of first snap-fit ​​members 35 are arranged along the second direction ( Figure 8 The second direction (as shown in the y-direction) protrudes into the first mounting cavity 31, wherein the second direction is perpendicular to the first direction, and the two sides of the thermal element 41 represent the two sides of the thermal element 41 in a third direction, which is perpendicular to both the first and second directions. Specifically, multiple first snap-fit ​​pieces 35 form a first limiting space 36, combined with... Figure 9 As shown, the thermal element 41 is disposed within the first limiting space 36, and the plurality of first snap-fit ​​pieces 35 can restrict the thermal element 41 in a third direction ( Figure 9 (shown in the z-direction) and the second direction ( Figure 9 Thermistor 41 moves in the first direction (y-direction). Figure 9 The limiting in the x-direction (as shown) can be achieved by providing corresponding reinforcing ribs on the fixing member 3 or by limiting the opposite end faces of the fixing member 3 in the first direction. Alternatively, the thermal element 41 can be limited in the first direction (as shown). Figure 9 Multiple first snap-fit ​​members are provided at opposite ends (in the x-direction shown). In this embodiment of the invention, by providing multiple first snap-fit ​​members to the fixing member, the first snap-fit ​​members can fix the thermal element, improving the stability of the installation between the thermal element and the fixing member, thereby improving the reliability of the door lock device.

[0070] In some embodiments, such as Figure 8 As shown, the first snap-fit ​​member 35 specifically includes a limiting part 351 and a protrusion 352, the limiting part 351 being along the second direction ( Figure 8 Extending in the y-direction (as shown), the limiting part 351 has two opposing ends in the second direction, one end of which is connected to the fixing member 3, and the other end is a free end. The other end of the limiting part 351 is connected to the protrusion 352, and the protrusion 352 is positioned relative to the limiting part 351 in the third direction (…). Figure 8 The protrusion is shown in the z-direction. Multiple protrusions 352 are located on opposite sides of the multiple first snap-fit ​​members 35.

[0071] Combination Figure 9 As shown, multiple limiting parts 351 can limit the thermal element in a third direction ( Figure 9 The protrusion 352 can limit the displacement of the thermal element in the second direction (as shown in the z-direction). Figure 9 The displacement is shown in the y-direction. Multiple limiting parts 351 are located in the third direction (as shown). Figure 9 The distance in the z-direction shown can be equal to the distance in the third direction of the thermistor 41. Figure 9The dimensions of the multiple protrusions 352 in the third direction are smaller than the dimensions of the thermal element 41 in the third direction. During the installation of the thermal element 41 in the first limiting space 36, the thermal element 41 abuts against the protrusions 352, so that the distance between the protrusions 352 in the third direction (as shown in the z-direction) is smaller than the dimensions of the thermal element 41 in the third direction. Figure 9 As shown in the z-direction, the protrusion 352 moves in a direction away from each other, causing the limiting part 351 to deform until the thermal element 41 has completely moved into the first limiting space 36. At this point, the protrusion 352 disengages from the thermal element 41 and returns to its initial position, abutting against the thermal element 41 in the second direction (as shown in the z-direction). Figure 9 At one end (in the y-direction shown), the limiting part 351 abuts against the thermal element 41 in the third direction ( Figure 9 The two ends (in the z-direction shown) securely define the position of the thermal element 41. In this embodiment of the invention, the snap-fit ​​component is configured as a limiting part and a protrusion. The limiting structure is simple, enabling rapid assembly of the thermal element and the fixing component, and ensuring stable assembly, which improves the reliability of the door lock device.

[0072] In some embodiments, such as Figure 10 As shown, the slider 42 includes an extension 421 and an abutment 422. The extension 421 is provided along a first direction ( Figure 10 The slide groove 423 extends in the x-direction shown, and the extension portion 421 is also configured as an elongated strip. The length direction of the extension portion 421 is in the first direction, that is, the extension direction of the slide groove 423 is consistent with the extension direction of the extension portion. The slide groove 423 is used to set the elastic element 5. Figure 7 As shown, a portion of the extension 421 is located within the second mounting cavity 32, and another portion of the extension 421 passes through the second through hole 34 and is disposed outside the second mounting cavity 32. The extension 421 is located in the first direction ( Figure 7 The extension 421 (in the x-direction shown) has two opposing ends, one end of which is located inside the second mounting cavity 32, and one end of the extension 421 is connected to the abutment 422. The other end of the extension 421 in the first direction is located outside the second mounting cavity. The thermal element 41 can at least partially pass through the first through hole 33 and abut against the abutment 422. It should be noted that abutting means close contact, but does not necessarily mean that the thermal element 41 and the abutment 422 have a direct connection relationship. By setting the thermal element 41 and the abutment 422 in abutting position, the thermal element 41 moving in the positive direction in the first direction can push the abutment 422 to move in the positive direction in the first direction.

[0073] Among them, such as Figure 7As shown, one end of the elastic member 5 abuts against the abutment portion 422. Of course, in some embodiments, one end of the elastic member 5 can also be fixedly connected to the abutment portion 422 to improve the stability of the connection between the elastic member 5 and the abutment portion 422. The other end of the elastic member 5 abuts against the base plate 371 of the fixing member 3. It should be noted that the base plate 371 is located at one end of the fixing member 3 in the first direction, and the base plate 371 is perpendicular to the first direction (…). Figure 7 (As shown in the x-direction) perpendicular, the second through hole 34 is provided on the base plate 371. By placing the elastic element 5 between the base plate 371 and the abutment part 422, the position of the base plate 371 remains unchanged. When the thermal element 41 moves, the abutment part 422 translates in the positive direction of the first direction, causing the abutment part 422 to move towards the base plate 371. The distance between the abutment part 422 and the base plate 371 decreases, causing the elastic element 5 between the base plate 371 and the abutment part 422 to gradually compress and deform. During the negative movement of the thermal element in the first direction, the force of the thermal element pressing on the abutment part 422 decreases. The restoring force of the elastic element 5 overcomes the squeezing force of the abutment part 422, causing the elastic element 5 to drive the abutment part 422 to move away from the base plate 371, thereby realizing the negative translation of the sliding member 42 in the first direction.

[0074] In this embodiment of the invention, the sliding member is configured as an abutment part and an extension part. The extension part can withstand the force applied by the thermal element and can move relative to the second through hole. This simplifies the structure of the sliding member and improves the reliability of the sliding member's movement, thereby improving the reliability of the door lock device installation.

[0075] In some embodiments, such as Figure 11 As shown, the fastener 3 also includes a plurality of second snap-fit ​​members 381. The plurality of second snap-fit ​​members 381 are arranged along a second direction ( Figure 11 (As shown) It is prominently positioned within the second mounting cavity 32. Combined with... Figure 7 As shown, multiple second connectors 381 are respectively disposed on the extension 421 in a third direction ( Figure 7 On both sides of the z-direction shown, the third direction is perpendicular to both the first and second directions; wherein, the distance between the plurality of second latching members 381 in the third direction is greater than the dimension of the extension 421 in the third direction and smaller than the dimension of the abutment 422 in the third direction. That is to say, the second latching members 381 can restrict the extension 421 in the third direction ( Figure 7 The extension 421 can move relative to the second snap-fit ​​member 381 in the first direction (as shown in the y-direction), but the extension 421 can move relative to the second snap-fit ​​member 381 in the first direction (as shown in the y-direction). Figure 7 The contact portion 422 moves in the first positive direction (as shown in the x direction), when the contact portion 422 moves in the first positive direction (as shown in the x direction). Figure 7When the extension part 422 moves to the direction indicated by the arrow in the x direction and abuts against the second latching member 381, the second latching member 381 restricts the abutting part 422 from moving further in the first direction. In this state, the other end of the extension part 421 has moved to the position that cooperates with the limiting groove. In this embodiment of the invention, by making the distance between the multiple second latching members in the third direction greater than the size of the extension part in the third direction, the second latching members can both restrict the movement of the extension part in the third direction and satisfy the movement of the extension part in the first direction, which is beneficial to improving the stability of the movement of the extension part. Furthermore, by making the distance between the multiple second latching members in the third direction less than the size of the abutting part in the third direction, while satisfying the movement of the extension part in the first direction, the movement stroke of the abutting part in the first direction can also be restricted, thereby improving the reliability of the movement of the sliding member in the first direction and improving the stability of the door lock device structure.

[0076] In some embodiments, such as Figure 7 As shown, the fixing member 3 is provided with a first direction ( Figure 7 A partition 372 perpendicular to the x-direction is provided. The partition 372 is located between the first mounting cavity 31 and the second mounting cavity 32. The partition 372 is provided with a first through hole 33 connecting the first mounting cavity 31 and the second mounting cavity 32. The fastener 3 is also provided with a connecting plate 373 parallel to the first direction. The connecting plate 373 connects the bottom plate 371 and the partition 372 to form the second mounting cavity 32.

[0077] like Figure 7 As shown, the fastener 3 also includes a third snap-fit ​​member 382 and a fixing plate. The third snap-fit ​​member 382 is along the second direction ( Figure 7 Extending in the y-direction (as shown), the direction in which the third latching member 382 extends indicates the direction of its maximum dimension. The third latching member 382 is disposed within the second mounting cavity 32, located between the abutment portion 422 and the partition plate 372. The third latching member 382 can limit the travel of the abutment portion 422 in the first direction, that is, the abutment portion 422 can move between the third latching member 382 and the second latching member 381.

[0078] like Figure 12 As shown, the fixing plate 39 is located within the second mounting cavity 32. The fixing plate 39 and the partition plate 372 are spaced apart and arranged parallel to each other. The fixing plate 39 can be used to close at least one side of the second mounting cavity 32, and plays a limiting role for components (e.g., sliding members) installed in the second mounting cavity 32. The fixing plate 39 installed in the second mounting cavity 32 mainly restricts the sliding member in the second direction ( Figure 12 The movement is shown in the y-direction.

[0079] In this embodiment, the fixing plate 39 is engaged with the third latching member 382 and / or the second latching member 381. That is, in this embodiment, the second latching member 381 and the third latching member 382 not only limit the sliding member, but the second latching member 381 and the third latching member 382 can be configured as the structure of the first latching member described in the above embodiment. In other words, the second latching member 381 and the third latching member 382 may include a limiting portion and a protrusion, with the limiting portion along the second direction (…). Figure 12 Extending in the y-direction, the protrusion is located at one end of the limiting part in the second direction. The protrusion can abut against the fixing plate 39 in the second direction, thereby limiting the fixing plate in the second direction. The limiting part can also limit the fixing plate in the first and third directions. By setting the second and / or third snap-fit ​​parts, the position of the fixing plate can be fixed, thereby improving the stability of the internal structure assembly of the door lock device.

[0080] In some embodiments, such as Figure 12 and Figure 7 As shown, the fastener 3 also includes a fourth latching member 383. The fourth latching member 383 extends along the second direction and is at least partially flush with the base plate 371. Specifically, the fourth latching member 383 may include a limiting portion and a protrusion, the limiting portion extending along the second direction (…). Figure 12 The protrusion extends in the y-direction (as shown), and the limiting part and the base plate 371 are located on the same plane. The protrusion is relative to the limiting part in the first direction ( Figure 12 The fourth snap-fit ​​member is used to snap the fixing plate 39 at one end in the first direction. For example, the protrusion of the fourth snap-fit ​​member abuts against the end face of the fixing plate 39 in the second direction, and the limiting part abuts against the end face of the fixing plate 39 in the first direction. By providing the fourth snap-fit ​​member in the fixing member, the present invention can improve the stability of the assembly of the fixing member and the fixing plate.

[0081] In some embodiments, such as Figure 13 As shown, the door lock device also includes a detection device 7. The detection device 7 is disposed within the second mounting cavity 32, in conjunction with... Figure 12 As shown, when the door lock device has a fixing plate 39, the detection device 7 is positioned between the fixing plate 39 and the connecting plate 373. (Combined with...) Figure 5 As shown, the detection device 7 is at least partially in the direction of a third party ( Figure 5The contact portion 422 of the slider 42 coincides with the contact portion 422 in the z-direction (as shown). The detection device 7 is used to detect the position of the slider 42 in the first direction. The detection device 7 can be configured as a micro switch. When the contact portion 422 moves to the set position, the contact portion 422 applies force to the actuating spring of the micro switch. When the actuating spring moves to the critical point, it generates an instantaneous action, causing the moving contact at the end of the actuating spring to quickly connect or disconnect with the fixed contact. When the force of the contact portion 422 on the micro switch is removed, the actuating spring generates a reverse action force. When the reverse stroke of the contact portion 422 reaches the action critical point of the actuating spring, the reverse action is completed instantaneously. In this embodiment of the invention, the state of the detection device being on is defined as the state of the door lock device locking the limiting groove, and the state of the detection device being off is defined as the state of the door lock device disengaging from the limiting groove. The detection device can then be used to monitor whether the position of the sliding member is consistent with the working state of the cooking equipment. For example, when the cooking equipment is in operation, to reduce the risk of burns to the user, the door needs to be locked using the door lock device. Therefore, the detection device monitors whether the sliding member extends into the limiting groove in this state. If it does, the position of the sliding member is normal; if not, the position of the sliding member is abnormal. When the detection device detects an abnormal sliding member position, it can report this information and issue a reminder to the user to improve the safety of using the cooking equipment.

[0082] In some embodiments, such as Figure 13 As shown, the second mounting cavity 32 of the fixing member 3 is provided with a protruding limiting member 72, and the detection device 7 is provided with a corresponding limiting hole 71. When the detection device 7 is assembled into the second mounting cavity 32, the limiting member 72 is inserted into the limiting hole 71, thereby achieving the positioning of the detection device 7 and the fixing member 3. This embodiment of the invention, by setting a matching structure between the limiting member and the limiting hole, is beneficial to improving the assembly efficiency of the detection device and the fixing member, and has a simple structure and a stable and reliable connection method.

[0083] This invention also provides a cooking device, such as... Figure 14 As shown, the cooking device includes a housing 8, a door 9, and a door lock device 2 according to any of the above embodiments. The housing 8 has a cavity 81 inside, which can be used to hold food to be cooked. The door 9 is movably connected to the housing 8 to open and close the cavity 81. It should be noted that the embodiments of the present invention do not limit the way the door 9 is connected to the housing 8. For example, the door 9 can be rotatably connected to the housing 8, or the door 9 can be translatably connected to the housing 8, as long as the door 9 can rotate relative to the housing 8 to open and close the cavity 81. When the cavity 81 is open, the user can take food into or out of the cavity. When the cavity 81 is closed, the cooking device is in a cooking state or a non-working state.

[0084] Among them, such as Figure 14As shown, the door body 9 is provided with a limiting groove 6, which is disposed on at least one surface that coincides with the housing 8; for example, Figure 14 As shown, in this embodiment of the invention, the limiting groove 6 is disposed on the door body 9 in the first direction ( Figure 14 The limiting groove 6 is located on one end face in the x-direction shown. Of course, in other embodiments, the limiting groove 6 can also be provided on the door body in a third direction (as shown). Figure 14 The two end faces on the direction perpendicular to the paper. For example... Figure 14 As shown, the door lock device 2 is disposed inside the housing 8, and at least part of the door lock device 2 can be positioned relative to the fixing member along the first direction ( Figure 14 The movable component moves in the x-direction (as shown) to extend into and disengage from the limiting groove 6. In this embodiment, the locking and unlocking of the door lock device with the limiting groove can be achieved through the reciprocating forward and reverse translation of the movable component in the first direction. This simplifies the movement of the door lock device, reduces its structural volume, lowers the difficulty of installation, and thus improves the assembly efficiency and reliability of the door lock device assembly.

[0085] In some embodiments, such as Figure 14 As shown, the housing 8 includes an inner liner 82 and a fixing frame assembly 83. The inner liner 82 has a receiving cavity 81, and the inner liner 82 is located in a second direction ( Figure 14 An opening 84 communicating with the receiving cavity 81 is provided on one side (in the y-direction shown). The door body 9 and the inner liner 82 are movably connected to open and close the opening 84. A fixed frame assembly 83 is disposed above the inner liner 82, and a door lock device 2 is disposed within the fixed frame assembly 83. The door lock device 2 is located in the second direction (in the y-direction shown). Figure 14 As shown in the y-direction, it coincides with the door body 9. This embodiment of the invention, by placing the door lock device within the fixed frame assembly, reduces the impact of the cumulative assembly gap between the inner liner, door body, and fixed frame assembly on the door lock device. This helps to reduce the difficulty of installing the door lock device, thereby improving the stability of its use.
