Description

Technical Field

[0001] The present application relates to the field of electrical appliance technology, and in particular to a door body and a cooking device. Background Art

[0002] In cooking equipment such as steamers and steam ovens, a sealing ring is usually provided between the inner pot and the door body to ensure that the cooking cavity enclosed by the inner pot and the door body is in a sealed state, so that the cooking cavity maintains a high pressure or high temperature environment, and prevents the heat in the cooking cavity from escaping from the gap between the door body and the inner pot, thereby improving cooking efficiency and saving energy.

[0003] However, due to the limitations of the sealing ring structure and material, the door body and the inner pot still leak water and air during long-term use of the cooking device. However, while the structure of the sealing ring is continuously improved to make it more compatible and fit the inner pot, the versatility of the sealing ring is reduced, and it is only compatible with a single model of cooking equipment, resulting in high cost of the cooking equipment. While the sealing ring is tightened during the production process of the cooking equipment, the sealing ring becomes loose due to repeated opening and closing of the door body during long-term use of the cooking equipment, and the problem of water and air leakage cannot be avoided. Therefore, the improvement of the conventional sealing ring structure and installation cannot improve the water and air leakage between the door body and the inner pot after long-term use of the cooking equipment in the prior art while taking into account versatility.

[0029] See also Figure 1 , Figure 1 The schematic diagram of the structure of a cooking device 100 in an embodiment of the present application is shown. In an embodiment of the present application, a cooking device 100 is provided, which can be a steam-bake machine, a steamer, an oven, etc., or any cooking device in the prior art. Figure 1 As shown, the cooking device 100 includes an inner pot 120 and a door body 110 as in any of the following embodiments, the inner pot 120 includes a cooking cavity 121 with an opening and a sealing strip 122 arranged around the opening, the cooking cavity 121 is used to cook food, and its opening is used to take and place food. The door body 110 is rotatably connected to the inner pot 120, the door body 110 covers the inner pot 120 and the inner plate 112 covers the opening, so that the door body 110 and the inner pot 120 are enclosed together to form a closed cooking cavity 121, and the sealing strip 122 is used to seal the gap that may exist between the door body 110 and the inner pot 120 to prevent the water vapor and heat inside the cooking cavity 121 from overflowing. The door body 110 rotates relative to the inner pot 120 to switch between an open state and a closed state. When the door body 110 is in the open state, food in the cooking cavity 121 can be taken in and out. When the door body 110 is in the closed state, the cooking device 100 can be used to cook food, and the door body 110 and the inner pot 120 squeeze the sealing strip 122 to seal the cooking cavity 121 through the sealing strip 122.

[0030] Combination Figures 2 to 3 As shown, Figures 2 to 4FIG. 1 is a schematic diagram showing the structure of a door body 110 in an embodiment of the present application. In an embodiment of the present application, a door body 110 is provided, which can be applied to the above-mentioned cooking device 100, and can also be applied to equipment such as ovens in other fields. Figure 2 and Figure 4 As shown, the door body 110 includes an outer plate 111, an inner plate 112 and a moving assembly 113, wherein the inner plate 112 is spaced apart from the outer plate 111, and the space between the inner plate 112 and the outer plate 111 forms a placement space 114. Taking the case where the door body 110 is applied to the above-mentioned cooking device 100 as an example, the space between the outer plate 111 and the inner plate 112 can also be used for heat insulation. Figure 2 and Figure 4 As shown, in this embodiment, the door body 110 further includes a side panel 115 connected between the outer panel 111 and the inner panel 112, and the side panel 115, the outer panel 111 and the inner panel 112 together enclose a placement space 114. In some embodiments, the inner panel 112 and the outer panel 111 are both glass parts.

[0031] Combination Figure 5 As shown, the moving assembly 113 is located in the placement space 114, and the moving assembly 113 connects the outer plate 111 and the inner plate 112 and is configured to drive the inner plate 112 to move closer to or away from the outer plate 111. When the door body 110 is in a closed state, the moving assembly 113 can drive the inner plate 112 to move in a direction away from the outer plate 111 to press the sealing strip 122, thereby obtaining a better sealing effect and enhancing the airtightness of the cooking cavity 121. When the door body 110 is in an open state, the moving assembly 113 can drive the inner plate 112 to move in a direction close to the outer plate 111 to reset, so as to prevent the inner plate 112 from protruding and scratching the user.

[0032] In the above scheme, a moving component 113 capable of driving the inner plate 112 to move is provided between the inner plate 112 and the outer plate 111 that are spaced apart, so that the inner plate 112 can move in a direction away from the outer plate 111, that is, in a direction of squeezing the sealing ring, so that the sealing ring between the door body 110 and the inner pot 120 obtains a better sealing effect, and it is not limited by the specifications of the sealing ring. Even if the sealing ring becomes loose after the cooking device 100 is used for a long time, the sealing ring can still be tightened to achieve a better and more stable sealing effect, thereby improving the problem of water and air leakage between the door body 110 and the inner pot 120 caused by the loosening of the sealing ring after the cooking device 100 is used for a long time in the prior art.

[0033] like Figure 2 , Figure 4 and Figure 5As shown, in one embodiment, the moving component 113 includes a first connecting member 1131 and a second connecting member 1132 that are arranged to move relative to each other, the first connecting member 1131 is provided with an inclined guide surface 11311 and is movably connected to one of the inner plate 112 and the outer plate 111, and the moving direction of the first connecting member 1131 is the projection direction of the inclined direction of the guide surface 11311 on the plane where the outer plate 111 is located, the second connecting member 1132 is movably arranged along the guide surface 11311 and is fixedly connected to the other of the inner plate 112 and the outer plate 111, when the second connecting member 1132 moves on the guide surface 11311 of the first connecting member 1131, since the guide surface 11311 is an inclined surface, when the second connecting member 1132 is located at different positions, the total height of the moving component 113 will change, thereby realizing that the interval between the inner plate 112 and the outer plate 111 increases or decreases, that is, the inner plate 112 moves in a direction away from or close to the outer plate 111.

[0034] like Figure 2 and Figure 5 As shown, in one embodiment, the first connecting member 1131 is slidably connected to the outer plate 111, and the second connecting member 1132 is fixedly connected to the inner plate 112. In other embodiments, the first connecting member 1131 may be slidably connected to the inner plate 112, and the second connecting member 1132 may be fixedly connected to the outer plate 111, and the movement of the first connecting member 1131 may also drive the interval between the inner plate 112 and the outer plate 111 to increase or decrease, that is, the inner plate 112 moves in a direction away from or close to the outer plate 111.

[0035] like Figure 2 and Figure 5 As shown, in one embodiment, the moving component 113 includes a slide rail 1133 connected to the outer plate 111, the slide rail 1133 is arranged along the moving direction of the first connecting member 1131, and the first connecting member 1131 is slidably connected to the slide rail 1133, so that the first connecting member 1131 can move relative to the outer plate 111, thereby driving the second connecting member 1132 and the inner plate 112 to move in a direction away from or close to the outer plate 111 through the movement of the inclined guide surface 11311.

[0036] like Figure 2 and Figure 5As shown, in one embodiment, the moving assembly 113 also includes a transmission member 1134, the transmission member 1134 includes a first transmission rod 11341 connected to the first connecting member 1131, and also includes a second transmission rod 11342 connected to the first transmission rod 11341, the first transmission rod 11341 rotates to drive the first transmission rod 11341 to move in the moving direction, thereby realizing the movement of the first connecting member 1131 in the moving direction. In this embodiment, the first transmission rod 11341 is provided with a gear structure, and the second transmission rod 11342 is provided with a rack structure that meshes with the gear to drive the first transmission rod 11341 to move in the moving direction when the first transmission rod 11341 rotates, thereby realizing the movement of the first connecting member 1131 in the moving direction. In other embodiments, the first transmission rod 11341 and the second transmission rod 11342 can also be driven by a worm gear.

[0037] The moving assembly 113 further includes a driving member (not shown) for driving the first transmission rod 11341 to rotate. In this embodiment, the driving member may be a driving motor. Preferably, the driving motor may be automatically started according to whether the door body 110 is closed to drive the moving assembly 113 to move the inner door, so as to automatically squeeze the sealing ring to obtain a better sealing effect when the door body 110 is closed, and automatically retract and reset when the door body 110 is opened. In other embodiments, the driving member may also be a manual rocker, etc.

[0038] like Figure 4 and Figure 5 As shown, in one embodiment, the second connecting member 1132 includes a connecting portion 11321 and a rolling portion 11322, the connecting portion 11321 is fixedly connected to the inner plate 112, and the rolling portion 11322 is rotatably connected to the connecting portion 11321 and rollingly connected to the guide surface 11311. In this embodiment, the rolling portion 11322 is a roller, and in other embodiments, the rolling portion 11322 may also be a ball.

[0039] like Figure 3 and Figure 5 As shown, in one embodiment, the door body 110 also includes a limit assembly 116, one end of the limit assembly 116 is connected to the inner plate 112, and the other end is connected to the outer plate 111, and the extendable length of the limit assembly 116 is a set length, so that when the moving assembly 113 drives the inner door to move, the limit assembly 116 can limit the interval distance change range between the inner door and the outer door, and can also support the inner door to prevent the second connecting member 1132 from continuing to slide on the inclined guide surface 11311 after the inner door moves into place.

[0040] It is understandable that the moving distance of the inner door can be adjusted according to the model and type of the cooking device 100 to improve its adaptability. For example, the moving distance of the inner door can be obtained based on multiple experiments during the production test of the cooking device 100, and the inner door can be moved to run the steaming function for 15 minutes without leaking water or air. The requirement that there is no outer panel 111 and the bottom condensation water tank, that is, no large amount of condensed water droplets and water mist under the control panel, is taken as the benchmark.

[0041] like Figure 3 As shown, in one embodiment, the limit assembly 116 includes a guide rail 1161 and a lifting plate 1162 that are slidably connected. The guide rail 1161 is connected to the outer plate 111 and is arranged perpendicular to the outer plate 111. Limiting portions 11611 are provided at both ends of the guide rail 1161. The guide rail 1161 includes a guide column portion 11612 and limiting portions 11611 located at both ends of the guide column portion 11612. The lifting plate 1162 slides along the guide rail 1161 and on the guide column portion 11612 between the two limiting portions 11611 of the guide rail 1161, and then the moving distance of the lifting plate 1162 is limited by the limiting portion 11611, and the lifting plate 1162 is fixedly connected to the inner plate 112 so that the lifting plate 1162 moves synchronously with the inner plate 112.

[0042] like Figure 3 As shown, the limiting assembly 116 also includes a moving block 1163 fixedly connected to one side of the lifting plate 1162, the moving block 1163 is provided with a through hole, the guide column portion 11612 is passed through the through hole to enable the lifting plate 1162 and the moving block 1163 to slide along the guide column portion 11612, and the limiting portion 11611 cannot be fully inserted into the through hole, so as to limit the lifting plate 1162 from continuing to move through the limiting portion 11611.

[0043] like Figure 2 and Figure 5 As shown, in one embodiment, the number of the limiting components 116 is at least 2, and the limiting components 116 are symmetrically arranged on both sides of the moving component 113, so that the inner door is subjected to force at multiple points to prevent the inner door from tilting when moving.

[0044] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
