Description

Technical Field

[0001] The present invention relates to the technical field of cooking devices, in particular to a door assembly and a cooking device. Background Art

[0002] The problem of preventing steam leakage has always been a difficult problem in the design of cooking devices. Currently, most steam and oven micro-cooking devices in the field of cooking kitchen appliances use the following two solutions to prevent water and air leakage: Solution 1, by continuously improving and updating the door sealing ring device; Solution 2, by manually adjusting and tightening the door sealing ring during the production process. In Solution 1, the door sealing ring structure is continuously improved. Although it has good one-to-one adaptability, it lacks universality, is costly, and consumes a lot of energy. In Solution 2, when manually adjusting, the door sealing ring will loosen due to long-term opening and closing of the door in real life, resulting in water and air leakage problems, which poses a safety hazard. Summary of the invention

[0003] Since the existing solutions for preventing steam leakage in cooking devices have poor versatility and the door sealing ring is prone to loosening during long-term use, it is necessary to provide a door assembly and a cooking device.

[0004] The door assembly is used to be rotatably connected to the box assembly, comprising:

[0005] outer panel;

[0006] An inner plate, the inner plate being movably mounted on the outer plate and used to abut against a door seal of the box assembly;

[0007] A driving member, comprising a fixed gear fixed to the box assembly and a movable gear mounted on the outer plate, the movable gear meshing with the fixed gear for forward rotation around the fixed gear when the door is closed and reverse rotation around the fixed gear when the door is opened; and

[0008] The transmission mechanism has an input end and an output end which are respectively connected to the moving gear and the inner plate so as to drive the inner plate away from the outer plate when the moving gear rotates forward and to drive the inner plate closer to the outer plate when the moving gear rotates reversely.

[0009] With this arrangement, the inner plate is automatically pressed against the door seal when the door is opened or closed. The structure is simple and the synchronization is good. The meshing connection of the fixed gear and the moving gear can ensure that the pressure of the inner plate against the door seal is consistent each time the door is closed, which is convenient for technicians to debug. Since there is no need for electric drive or user-assisted tightening, the entire door assembly has a high degree of automation. Furthermore, the tooth ratio of the fixed gear and the moving gear can be adjusted to achieve quantitative adjustment of the pressure of the inner plate against the door seal, and the maintenance cost is low.

[0010] In one embodiment, the transmission mechanism includes a first slider slidably mounted on the outer plate, a second slider fixedly connected to the inner plate, and a conversion member providing the input end and transmission-connected to the first slider to drive the first slider to slide along the outer plate;

[0011] The first sliding block has a guiding inclined surface arranged obliquely to the outer plate along a sliding direction of the first sliding block, and the second sliding block abuts against the guiding inclined surface to be moved away from the outer plate under the drive of the first sliding block.

[0012] Such a configuration is adapted to the thin thickness of the door assembly, and the configuration of the guiding slope also increases the force arm when driving the second slider to move, thereby reducing the resistance to opening and closing the door.

[0013] In one embodiment, the conversion member includes a transmission shaft, a conversion gear mounted on the transmission shaft, and a rack meshed with the conversion gear, the rack is fixedly connected to the first slider, and the movable gear is mounted on the transmission shaft.

[0014] In this way, the transmission shaft is not only used to transmit the power of the moving gear to the conversion gear, but also facilitates the adjustment of the position of the conversion gear. When the positions of the first slider and the second slider are changed, only the corresponding positions of the conversion gear need to be adjusted, and the power transmission path will not be interrupted. Therefore, the entire transmission mechanism is flexible to adjust and has strong adaptability.

[0015] In one embodiment, there are at least two movable gears, which are spaced apart and arranged on both sides of the conversion gear.

[0016] With this arrangement, the transmission shaft and the outer plate are evenly stressed and deform less during long-term use.

[0017] In one embodiment, a first guide rail is provided on the side of the outer plate facing the inner plate, and the first slider includes a base plate portion and a sliding portion and a wedge-shaped portion respectively fixed on both sides of the base plate portion, the sliding portion can be slidably mounted on the first guide rail, and the guiding slope is located on the side of the wedge-shaped portion away from the base plate.

[0018] With such arrangement, under the guidance of the first guide rail, the first sliding block slides smoothly and is not prone to tipping over or deflecting.

[0019] In one of the embodiments, the first sliding block further includes a stopper located at a side of the guiding inclined surface away from the door assembly and protruding from the guiding inclined surface.

[0020] With such arrangement, the second slider is limited by the stopper to prevent the second slider from slipping off the guiding inclined surface.

[0021] In one embodiment, the second sliding block includes a base mounted on the inner plate and a roller mounted on an end of the base away from the inner plate, and the roller abuts against the guiding inclined surface.

[0022] Such an arrangement increases the smoothness of the cooperation between the first slider and the second slider.

[0023] In one embodiment, the inner plate includes a plate body spaced apart from the outer plate and a connector extending from the plate body toward the outer plate. A second guide rail is also provided on the side of the outer plate facing the inner plate, and the connector can be slidably mounted on the second guide rail.

[0024] With such arrangement, the second guide rail provides a preset direction for the movement of the inner plate, thereby increasing the stability of the movement of the inner plate.

[0025] In one embodiment, the second guide rail includes a track rod and a stop ring located at one end of the track rod away from the outer plate, the connecting body includes a connecting portion and a sleeve portion fixedly connected to a side of the connecting portion away from the plate body, the sleeve portion is movably sleeved on the track rod, and the stop ring is used to axially abut against the sleeve portion;

[0026] The door assembly further comprises an elastic member located between the outer plate and the inner plate, and two ends of the elastic member are respectively connected to the stop ring and the plate body.

[0027] In this way, the elastic member increases the connection force between the outer plate and the inner plate, tightens the inner plate and the outer plate to each other, and prevents the inner plate from shaking relative to the outer plate.

[0028] The present application also provides a cooking device, comprising:

[0029] A box assembly, comprising an inner tank body having an opening and a door seal installed at the opening; and

[0030] As the door assembly mentioned above, the door assembly is rotatably mounted on the inner container body and abuts against the door seal.

[0031] With such an arrangement, the door assembly provided by the present application is utilized, and the inner panel and the door seal can be further compressed when the door is closed, thereby avoiding and reducing the risk of steam leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The problem of preventing steam leakage has always been a difficult problem in the design of cooking devices. Currently, most steam and oven micro-cooking devices in the field of cooking kitchen appliances use the following two solutions to prevent water and air leakage: Solution 1, by continuously improving and updating the door sealing ring device; Solution 2, by manually adjusting and tightening the door sealing ring during the production process. In Solution 1, the door sealing ring structure is continuously improved. Although it has good one-to-one adaptability, it lacks universality, is costly, and consumes a lot of energy. In Solution 2, when manually adjusting, the door sealing ring will loosen due to long-term opening and closing of the door in real life, resulting in water and air leakage problems, which poses a safety hazard.

[0049] Based on this, it is necessary to provide a door assembly 100 and a cooking device that can actively increase the door closing force and have a lower cost.

[0050] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 , Figure 1 This is a schematic diagram of the structure of a cooking device in an embodiment provided in the present application. Figure 2 for Figure 1 A schematic structural diagram of the middle door assembly 100, Figure 3 for Figure 2 The partial structural schematic diagram of the door assembly 100 is shown in FIG. Figure 5 for Figure 3The cooking device provided in the present application comprises a box assembly 200 and a door assembly 100. The box assembly 200 comprises an inner pot body with an opening and a door seal installed at the opening. The door assembly 100 is rotatably installed at the inner pot body and abuts against the door seal. The door assembly 100 includes an outer plate 10, an inner plate 20, a driving member 30 and a transmission mechanism 40. The inner plate 20 can be movably mounted on the outer plate 10 and is used to abut the door seal of the box assembly 200. The driving member 30 includes a fixed gear 31 and a moving gear 32. The fixed gear 31 is fixed to the box assembly 200, and the moving gear 32 is mounted on the outer plate 10. The moving gear 32 is meshed with the fixed gear 31. When the door is closed, the moving gear 32 rotates forward around the fixed gear 31, and when the door is opened, the moving gear 32 rotates reversely around the fixed gear 31. The input end and the output end of the transmission mechanism 40 are respectively connected to the moving gear 32 and the inner plate 20. When the moving gear 32 rotates forward, the transmission mechanism 40 drives the inner plate 20 away from the outer plate 10 to press the door seal. When the moving gear 32 rotates reversely, the transmission mechanism 40 drives the inner plate 20 to approach the outer plate 10 and away from the door seal. In this way, the inner panel 20 is automatically pressed against the door seal when the door is opened or closed. The structure is simple and the synchronization is good. The meshing connection of the fixed gear 31 and the moving gear 32 can ensure that the pressure of the inner panel 20 on the door seal is consistent each time the door is closed, which is convenient for technicians to debug. Since there is no need for electric drive or user-intermediate compression, the entire door assembly 100 has a high degree of automation. Furthermore, the tooth ratio of the fixed gear 31 and the moving gear 32 can be adjusted to achieve quantitative adjustment of the pressure of the inner panel 20 on the door seal. It has good versatility and low maintenance costs.

[0051] See also Figure 3 , Figure 3 for Figure 2 A partial structural diagram of the door assembly 100 is shown. Specifically, in one embodiment provided in the present application, the transmission mechanism 40 includes a first slider 41, a second slider 42 and a conversion member 43, the first slider 41 is slidably mounted on the outer panel 10, the second slider 42 is fixedly connected to the inner panel 20, the conversion member 43 is transmission-connected to the first slider 41 and provides an input end to drive the first slider 41 to slide along the outer panel 10, the first slider 41 has a guide slope 4101 arranged along the sliding direction of the first slider 41 and inclined to the outer panel 10, and the second slider 42 abuts against the guide slope 4101 to move away from the outer panel 10 under the drive of the first slider 41. In other words, the conversion member 43 is used to convert the rotation of the movable gear 32 into the sliding of the first slider 41 along the outer panel 10. Under the guidance of the guide slope 4101, the second slider 42 is forced to move away from the outer panel 10 or is able to move closer to the outer panel 10. This arrangement takes into account the thin thickness of the door assembly 100. The length of the guide slope 4101 along its own sliding direction is greater than the height of the guide slope 4101 along the thickness direction of the door assembly 100. The setting of the guide slope 4101 also increases the force arm when driving the second slider 42 to move, thereby reducing the resistance to opening and closing the door.

[0052] Please continue reading Figure 3 Further, in an embodiment provided by the present application, the conversion member 43 includes a transmission shaft 431, a conversion gear 432 and a rack 433, the conversion gear 432 is mounted on the transmission shaft 431, the rack 433 is fixedly connected to the first slider 41, and the moving gear 32 is mounted on the transmission shaft 431. The setting of the transmission shaft 431 is not only used to transmit the power of the moving gear 32 to the conversion gear 432, but also facilitates the adjustment of the position of the conversion gear 432. When the positions of the first slider 41 and the second slider 42 are changed, it is only necessary to adjust the corresponding position of the conversion gear 432, and the power transmission path will not be interrupted. Therefore, the entire transmission mechanism 40 is flexible to adjust and has strong adaptability. In addition, the rack 433 and the power gear occupy less space inside the door assembly 100, which is conducive to optimizing the internal space of the door assembly 100. Optionally, in an embodiment provided by the present application, the number of the moving gears 32 is at least two and they are arranged at intervals on both sides of the conversion gear 432. In this way, the transmission shaft 431 and the outer plate 10 are evenly stressed and less deformed during long-term use.

[0053] Please refer again Figure 2 , Figure 3 and Figure 5 Optionally, in order to ensure precise meshing of the moving gear 32 and the fixed gear 31, the door assembly 100 also includes a connecting rod 33 whose two ends are rotatably connected to the transmission shaft 431 and the fixed gear 31 respectively. It can be understood that the connecting rod 33 can also be connected to the box assembly 200 as long as it does not affect the rotation of the moving gear 32 around the fixed gear 31.

[0054] See also Figure 3 and Figure 6 , Figure 6 for Figure 3 In the structural diagram of the first slider 41, in order to ensure the smooth sliding of the first slider 41, in one embodiment provided in the present application, a first guide rail 50 is provided on the side of the outer plate 10 facing the inner plate 20, and the first slider 41 includes a base plate portion 411 and a sliding portion 412 and a wedge-shaped portion 413 respectively located on the front and back sides of the base plate portion 411, the sliding portion 412 is slidably sleeved on the first guide rail 50, and the guiding inclined surface 4101 is located on the side of the wedge-shaped portion 413 away from the base plate. Specifically, the number of the first guide rails 50 is a pair and arranged at intervals. It can be understood that in other embodiments, the number of the first guide rails 50 can also be one and the cross section of the first guide rail 50 can also be non-circular, so that the smooth sliding of the first slider 41 can also be ensured.

[0055] See also Figure 3 and Figure 6Optionally, the first slider 41 further includes a stopper 414, which is located on a side of the guide slope 4101 away from the door assembly 100 and protrudes from the guide slope 4101. In this way, the stopper 414 limits the second slider 42 to prevent the second slider 42 from slipping off the guide slope 4101.

[0056] See also Figure 3 and Figure 7 , Figure 7 for Figure 3 Schematic diagram of the structure of the second slider 42. Optionally, in order to increase the smoothness of the cooperation between the first slider 41 and the second slider 42, the second slider 42 includes a base 421 and a roller 422 installed on the base 421, the base 421 is fixedly connected to the inner plate 20, and the roller 422 abuts against the guide slope 4101.

[0057] See also Figure 3 , Figure 4 and Figure 8 , Figure 4 for Figure 3 A partial enlarged view of the X in the middle.

Optionally, in order to increase the stability of the movement of the inner panel 20, in an embodiment provided in the present application, a second guide rail 60 is further provided on the side of the outer panel 10 facing the inner panel 20, and the inner panel 20 includes a panel body 21 and a connector 22 extending from the panel body 21 toward the outer panel 10, and the connector 22 is slidably mounted on the second guide rail 60. Specifically, the extension direction of the second guide rail 60 matches the direction in which the inner panel 20 actually needs to move, and preferably, the extension direction of the second guide rail 60 is perpendicular to the panel surface of the outer panel 10. The second guide rail 60 includes a track rod 61 and a stop ring 62 located at one end of the track rod 61 away from the outer plate 10. The connecting body 22 includes a connecting portion 221 and a sleeve portion 222. The connecting portion 221 is fixedly connected to the plate body 21. The sleeve portion 222 is fixedly connected to the side of the connecting portion 221 away from the plate body 21. The sleeve portion 222 is movably sleeved on the track rod 61. The stop ring 62 is used to abut against the sleeve portion 222 along the axial direction. In order to prevent the inner plate 20 from shaking, the door assembly 100 also includes an elastic member 70 located between the outer plate 10 and the inner plate 20. For example, the two ends of the elastic member 70 are respectively connected to the stop ring 62 and the plate body 21. The elastic member 70 tightens the inner plate 20 and the outer plate 10 to prevent the inner plate 20 from shaking relative to the outer plate 10.
