Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and in particular to a foldable vegetable warming board. Background Art

[0002] With the improvement of the quality of life, people's requirements for the diversity and richness of food cooking in daily cooking are also increasing. However, due to factors such as the number of cooking tools, many dishes often require a certain amount of cooking time before they can be put on the table. While waiting for all the dishes to be cooked, the dishes placed first often get cold and cause the flavor to be lost, thus affecting the dining experience of diners, so the warming board came into being. The warming board is mainly used to keep the food warm. It can continuously provide heat for the food and keep the food hot without secondary heating. The warming boards on the market are rectangular and round in shape. The principle is to turn on the power to make the internal material of the insulation board heat up, and then make the panel heat up through heat conduction, and then the tableware placed on top of the panel will be heated and maintain a certain temperature.

[0003] The Chinese patent with patent number 202210537919.9 discloses a zoned temperature-controlled foldable food warming plate, comprising at least two electric heating plates hinged end to end, and two adjacent electric heating plates are hinged by a rotating shaft. The side wall of the electric heating plate is provided with a U-shaped rotating shaft groove, and the side wall of the rotating shaft groove is provided with a rotating shaft hole. The rotating shaft includes a rotating shaft body and a rotating shaft column vertically arranged on both sides of the rotating shaft body, the rotating shaft body is embedded in the rotating shaft groove and the rotating shaft column is plugged into the rotating shaft hole, and a wire passage connecting the two rotating shaft columns is provided in the rotating shaft body. The rotating shaft groove is arranged at both ends of the electric heating plate, which makes a large gap between each electric heating plate when the electric heating plate is spread out for use. This gap increases the occupied space of the food warming plate. In addition, since there is a large gap between each electric heating plate, the two adjacent electric heating plates will become loose after long-term use. Utility Model Content

[0041] In order to enable those skilled in the art to better understand the technical solution of the present disclosure, the present disclosure is described in detail, clearly and completely in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are not used to limit the present disclosure.

[0042] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0043] Please see Figures 1 to 9 As shown, an embodiment of the present disclosure provides a foldable vegetable warming board, which is rectangular and includes a connecting plate and two or three mutually connected square heating plates 1. Specifically, the heating plate 1 includes a panel and a bottom shell. At least one side of the bottom shell is provided with an L-shaped recess 3 of a "U"-shaped structure. The L-shaped recess 3 extends along the length direction of the heating plate 1, so that the L-shaped recess 3 has a considerable length. The openings of the L-shaped recesses 3 of the two adjacent bottom shells are butted together to form a long strip installation groove. The connection of the openings of the L-shaped recesses 3 of the adjacent bottom shells is almost completely fitted. After the two heating plates 1 are connected and then spread out, there will be no large gap at the connection, and the structure is relatively compact. The connecting plate is arranged at the L-shaped recess 3 for connecting the two adjacent heating plates 1. The two side walls of the L-shaped recess 3 are respectively provided with connecting shafts 5. The connecting shaft 5 extends along the length direction of the heating plate 1. The connecting plate is provided with an axis hole rotatably connected to the connecting shaft 5. After the vegetable warming board is folded, each heating plate 1 is parallel to each other. The connecting plate includes a detachably connected mounting plate 11 and a cover plate 2, wherein the mounting plate 11 is located below the connecting shaft 5, and the cover plate 2 is located above the connecting shaft 5, and the cover plate 2 is used to cover the mounting groove. When there are two heating plates 1, the two heating plates 1 can be folded along the connection between the two after use.

[0044] Further, in order to facilitate the installation of the connecting shaft 5, the mounting plate 11 and the cover plate 2 are connected by screws, buckles or adhesive. The connecting shaft 5 is a hollow shaft, which is convenient for the wire 22 to pass through. A plurality of wires 22 are arranged in the connecting shaft 5, and the plurality of wires 22 are divided into two groups. The two groups of wires 22 enter the adjacent bottom shell through the connecting shaft 5 on the two opposite side walls of the L-shaped concave 3. Such a setting can facilitate the wire 22 to pass through, and can also reduce the outer diameter of the connecting shaft 5, so that the overall thickness of the heating plate 1 is thinner, making the structure more compact and the preparation cost lower.

[0045] The mounting plate 11 is provided with an arc-shaped first mounting portion 14, and the cover plate 2 is provided with an arc-shaped second mounting portion 16. The axial hole is formed by the first mounting portion 14 and the second mounting portion 16. After the cover plate 2 is connected to the mounting plate 11, the axial hole is formed. It is more convenient to assemble the connecting plate into the mounting plate 11 and the cover plate 2. During assembly, the mounting plate 11 is installed first and then the cover plate 2 is installed. Since the axial hole is formed by the arc-shaped first mounting portion 14 and the second mounting portion 16, the structural strength of the axial hole is greater. In addition, the mounting plate 11 is provided with a first curved surface on both sides, and the cover plate 2 is provided with a second curved surface on both sides. After the mounting plate 11 and the cover plate 2 are connected, the end of the first curved surface fits the end of the second curved surface. In this way, after the mounting plate 11 and the cover plate 2 are connected, the side of the connecting plate forms a closed structure, which makes the strength of the connecting plate higher and the structural stability higher, so that the connection of the adjacent heating plates 1 is more stable and reliable. On the other hand, the side of the connecting plate is a closed structure to prevent foreign objects from entering. It is understandable that the thickness of the connecting plate is smaller than that of the heating plate. After the connecting plate is connected to the L-shaped recess 3, the bottom surface of the cover plate 2 should be at the same height as the bottom surface of the heating plate 1. In this way, the bottom of the warm food plate will be flatter when it is spread out for use.

[0046] In order to make the structure of the two heating plates 1 more stable after being connected, the length of the L-shaped recess 3 is greater than or equal to one-half of the length of the side of the heating plate 1, and the length of the mounting plate 11 is adapted to the width of the L-shaped recess 3. The width of the L-shaped recess 3 is set to ensure the stability of the connection of the heating plate 1. The longer the length of the L-shaped recess 3, the longer the length of the mounting plate 11. The mounting plate 11 serves as a connecting hub between two adjacent heating plates 1. The longer the length, the more stable the connection of the heating plates 1, and the heating plates 1 will not shake when folded or spread out. Preferably, the width of the L-shaped recess 3 is greater than or equal to two-thirds of the length of the side of the heating plate 1.

[0047] Please see Figure 3 , Figure 4 , Fig.10 , Fig.11 and Fig.13As shown, the food warming plate in the present disclosure can be heated in different zones, that is, each heating plate 1 can be heated to a corresponding temperature individually, so each heating plate 1 is provided with a temperature sensor and a heating mechanism, and the heating mechanism and the temperature sensor need to correspond to different circuits respectively. In order to better and reasonably arrange the wires 22 (or circuits) inside each heating plate 1, the bottom shell is provided with a cavity and a first channel 20, the connecting shaft 5 is a columnar structure, the connecting shaft 5 is provided with a second channel 6, the connecting shaft 5 is arranged at one end of the first channel 20, one end of the first channel 20 is connected to the second channel 6, the other end of the first channel 20 is connected to the cavity, and the second channel 6 and the first channel 20 are both for the wire 22 to pass through. The circuits of the temperature sensor and the heating mechanism enter the first channel 20 from the cavity, and then enter the second channel 6 from the first channel 20, so that the circuits can be arranged in an orderly manner. Since the connecting shaft 5 is arranged on the heating plate 1, when the food warming plate is folded or unfolded, the connecting shaft 5 will not rotate relative to the heating plate 1, that is, the circuit will not rotate relative to the connecting shaft 5 in the second channel 6, which avoids pulling on the circuit, thereby causing the circuit to loosen or be damaged. In order to better fix the circuit, a second protrusion 8 is arranged on the central axis of the mounting plate 11. The second protrusion 8 is a convex block structure and is arranged between the two first mounting portions 14.

[0048] like Figure 8 As shown, in one embodiment of the present disclosure, a first protrusion 7 is provided on the mounting plate 11, and the first mounting portion 14 is at least partially located on the first protrusion 7, that is, the arc structure of the first mounting portion 14 is formed on the first protrusion 7. The first protrusion 7 has a certain thickness, and the arc structure formed on the first protrusion 7 will not weaken the structural strength of the part, and at the same time, the connecting shaft 5 can be more closely fitted with the arc structure, thereby preventing the heating plate 1 from shaking when folded or spread out.

[0049] Please also refer to Figure 1 , Figure 8 and Fig. 9 As shown, since the circuit is partially arranged in the mounting groove, the cover plate 2 covers the circuit after being installed on the mounting plate 11 to prevent the circuit from being exposed to the outside. On the one hand, it protects the circuit, and on the other hand, it is safer when using the warming plate. Preferably, a first working hole 13 is provided on the mounting plate 11, and a second working hole 18 is provided on the cover plate 2. The inner peripheral wall of the first working hole 13 is provided with a thread, and the mounting plate 11 and the cover plate 2 are connected by bolts. In order to strengthen the connection between the mounting plate 11 and the cover plate 2, a first clamping member 9 is also provided on the mounting plate 11, and a first clamping groove 19 is provided on the cover plate 2. After the mounting plate 11 is connected to the cover plate 2, the first clamping member 9 is at least partially located in the first clamping groove 19.

[0050] Furthermore, a first reinforcing rib 12 is provided on the mounting plate 11, and a first working hole 13 is provided on the first reinforcing rib 12. Specifically, the first reinforcing rib 12 includes convex strips arranged transversely and longitudinally, and the first working hole 13 is provided at the intersection of the transverse arrangement and the longitudinal arrangement. The first reinforcing rib 12 is provided to enhance the structural strength of the mounting plate 11. If the first working hole 13 is directly opened on the mounting plate 11, the strength of the mounting plate 11 may be affected. In addition, a second reinforcing rib 17 is provided on the cover plate 2, and a second working hole 18 is provided on the second reinforcing rib 17. The second reinforcing rib 17 includes convex strips arranged transversely and longitudinally, and the second working hole 18 is provided at the intersection of the transverse arrangement and the longitudinal arrangement. The second reinforcing rib 17 is provided to enhance the structural strength of the cover plate 2.

[0051] It should be noted that the heating plate 1 also includes a heating layer. Specifically, the heating layer is located below the panel, and there are three heating plates 1, one of which is provided with a control board, and the heating layers are all electrically connected to the control board, and the control board can individually control the heating of each heating layer. When in use, the panel is placed facing upward, and the dinner plate is placed directly on the panel. The L-shaped recess 3 is arranged on the back of the bottom shell, and the cavity and the first channel 20 are arranged on the front of the bottom shell. Since most of the circuits are located in the cavity, in order to ensure a better arrangement of the circuits in the cavity, the cavity is provided with a plurality of limit buckles 21 for limiting and fixing the circuits. More specifically, the panel is made of glass or metal, the control board is arranged on the panel, the heating layer is a graphene film, and the present disclosure uses a graphene film as a heating mechanism, and the bottom shell is a plastic layer, and a non-slip pad 10 made of silicone or rubber is provided at the bottom. After the warm food plate is folded, the sizes of the heating plates 1 from the innermost layer to the outermost layer increase successively, so that the outermost heating plate 1 can wrap the other heating plates 1, making it more convenient to take them, and the outer heating plates 1 can also protect the inner heating plates 1.

[0052] In particular, the side of the bottom shell provided with the L-shaped concave 3 is a connecting side, and the side without the L-shaped concave 3 is a free side, and the free side is provided with an inclined surface 4, which is inclined from the back side of the bottom shell to the front side of the bottom shell. Since the panel of the heating plate 1 is made of glass or metal, it has a large weight, and the glass is relatively smooth, especially when there are a large number of heating plates 1, the entire warming plate is very heavy and inconvenient to take when using. The setting of the inclined surface 4 makes it easier for users to take the warming plate more conveniently.

[0053] Of course, the number of heating plates 1 can also be three or four, and the specific number of heating plates 1 is not limited here. Figure 1 and Fig.12As shown, when there are three heating plates 1, the two sides of the heating plate 1 in the middle are both provided with L-shaped recesses 3, and the depths of the L-shaped recesses 3 are different, one L-shaped recess 3 is deeper, and the other L-shaped recess 3 is deeper. When the heating plate 1 in the middle is connected to the other two heating plates 1, the depths of the L-shaped recesses 3 of the other two heating plates 1 match the depth of the heating plate 1 in the middle. The different depths of the L-shaped recesses 3 on both sides of the heating plate 1 in the middle are set to facilitate the folding and storage of the warming plate. Fig.12 It can be seen that the size of the heating plate 1 located in the middle after folding is smaller than the size of the outer heating plates 1. The purpose is to make each heating plate 1 basically parallel to each other after folding. Therefore, this setting also makes the folding type. The size of the connecting plate between the first heating plate 1 and the second heating plate 1 and the connecting plate between the second heating plate 1 and the third heating plate 1 is just the thickness of one heating plate 1. Therefore, after folding, from the innermost to the outermost connecting plate, the width between adjacent connecting plates is the thickness of one heating plate 1. For the convenience of description, the heating plate 1 located in the middle is defined as the first plate, the heating plate 1 connected to the shallower L-shaped concave 3 of the first plate is defined as the second plate, and the heating plate 1 connected to the deeper L-shaped concave 3 of the first plate is defined as the third plate. When folding, the second plate is first folded on the first plate, and then the third plate is folded on the second plate. It can be understood that when folded, the glass surface of the second plate faces the glass surface of the first plate, and the glass surface of the third plate faces the plastic surface of the second plate. Since an anti-slip pad 10 is provided at the bottom of the plastic surface, the anti-slip pad 10 is made of rubber or silicone material and can play a buffering role to avoid bumps between the glass surfaces. In addition, when the warming board is unfolded for use, the anti-slip pad 10 can also play an anti-slip role.

[0054] The present application is described in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the present application and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
