Description

Technical Field

[0001] The utility model relates to the technical field of heating appliances, in particular to a warm dish board. Background Art

[0002] Daily meals are very important to people. However, due to reasons such as climate, indoor temperature, and dining time, the dishes may gradually cool down over time, affecting the taste and people's physical health. The warm dish board can heat and keep warm the dishes placed on it, so that the dishes will not cool down, and it is deeply loved by people.

[0003] Common warm dish boards usually include a control device and a dish board body. Among them, a heating component is arranged in the dish board body, and the heating component is used to heat the dish board body. The control device is arranged at one end of the dish board body. The control device includes a housing, and the housing is hermetically connected to the dish board body, and a sealed cavity is formed between the housing and the dish board body. A circuit board is arranged in the sealed cavity, and the circuit board is electrically connected to the heating component to control the heating component to generate heat.

[0004] However, during daily use, some moisture may enter the housing of the control device. When the circuit board is working, it will generate heat, which causes the moisture in the housing to evaporate, resulting in an increase in the air humidity inside the housing. Since the space between the housing and the dish board body is a relatively sealed cavity, the humid air is not easy to discharge, so it is easy to cause a short circuit between the components on the circuit board. Summary of the Utility Model

[0005] The utility model provides a warm dish board, which has good exhaust performance and can solve the problem that the components on the circuit board are prone to short circuit in the related art.

[0006] An embodiment of the utility model provides a warm dish board, which includes a dish board body, a first housing and a second housing. Among them, in the thickness direction of the dish board body, the first housing and the second housing are arranged opposite to each other, and the first housing is located at the top of the second housing. One end of the dish board body is clamped between the first housing and the second housing, and a receiving cavity is formed among the first housing, the second housing and the dish board body. A circuit board is arranged in the receiving cavity, a heating body is arranged in the dish board body, and the circuit board is electrically connected to the heating body. An exhaust pipe is further arranged in the receiving cavity, a through hole is arranged on the first housing or the second housing, and one end of the exhaust pipe is located in the receiving cavity and the other end is communicated with the through hole.

[0007] The vegetable warming board in the embodiment of the present application can have a heating function by providing a heating body in the vegetable warming board body, and can heat the food placed on the vegetable warming board body when in use to prevent the food from getting cold. By providing a first shell and a second shell, and sandwiching the vegetable warming board body between the first shell and the second shell, the vegetable warming board body can be fixed, and a mounting position can be provided for the circuit board and the exhaust pipe, etc. By providing an exhaust pipe, the accommodating cavity formed between the first shell, the second shell and the vegetable warming board body can be exhausted to prevent the moisture in the accommodating cavity from causing a short circuit between the components on the circuit board, thereby extending the service life of the vegetable warming board.

[0008] In a possible implementation, the end of the exhaust pipe away from the through hole is located on a side of the circuit board away from the second shell. In the thickness direction of the cutting board body, the distance from the end of the exhaust pipe away from the through hole to the bottom end of the second shell is greater than the distance from the through hole to the bottom end of the second shell.

[0009] By setting the exhaust pipe at one end close to the circuit board, moisture near the circuit board can be easily discharged, thereby improving the safety of the food warming board. By making the distance from the end of the exhaust pipe away from the through hole to the bottom of the second shell larger than the distance from the through hole to the bottom of the second shell, moisture condensed in the exhaust pipe can be easily discharged.

[0010] In a possible implementation manner, a slot structure is provided on the circuit board, and an end of the exhaust pipe facing away from the through hole is located in the slot structure.

[0011] By providing a slotted structure on the circuit board, the exhaust pipe can be fixed on the circuit board, and one end of the exhaust pipe is always located near the circuit board, thereby removing moisture near the circuit board and improving the safety performance of the food warming board.

[0012] In a possible implementation, a tubular wall is provided at one end of the through hole facing the accommodating cavity, and the exhaust pipe is plug-fitted with the tubular wall.

[0013] Such an arrangement can facilitate the fixing of the exhaust pipe, reduce the difficulty of assembly, and thus save assembly costs.

[0014] In a possible implementation, there are multiple exhaust pipes, wherein the first shell or the second shell is provided with multiple through holes, and one exhaust pipe corresponds to one through hole. The multiple exhaust pipes are arranged at intervals along the width direction of the warm vegetable board. The width direction is perpendicular to the thickness direction of the vegetable board body.

[0015] With such a setting, the accommodation cavity can include multiple exhaust channels, improving the exhaust performance of the accommodation cavity to prevent short circuits between components on the circuit board due to moisture in the accommodation cavity, thereby extending the service life of the warm food plate.

[0016] In a possible implementation, the exhaust pipe is a silicone hose.

[0017] With such a setting, the exhaust pipe can be of a soft structure, facilitating bending to avoid some components during installation, thereby reducing the assembly difficulty.

[0018] In a possible implementation, support feet are provided at the bottom of the food plate body, and a plurality of the support feet are spaced apart and distributed at the bottom of the food plate body.

[0019] By providing the support feet, the food plate body can be conveniently supported. By spacing the plurality of support feet, gaps can be formed between the support members. When the food plate body is working, heat can be dissipated from below the food plate body, preventing the heat below the food plate body from being unable to escape and causing the area below the food plate body to overheat and easily scald the user.

[0020] In a possible implementation, a one-way valve is provided in the through hole (221). The one-way valve is used to control the flow of fluid from the exhaust pipe (40) to the outside of the through hole (221).

[0021] By providing a one-way valve in the through hole, the fluid (liquid, gas, water vapor, etc.) in the exhaust pipe can be discharged unidirectionally from the through hole, preventing the fluid outside the warm food plate from entering the accommodation cavity through the through hole, especially preventing liquid from entering the accommodation cavity and causing short circuits between components on the circuit board, thereby affecting the use of the warm food plate.

[0022] In a possible implementation, the food plate body is a silicone food plate body.

[0023] By setting the food plate body as a silicone food plate body, the food plate body can be of a soft structure and can be folded or rolled up during storage, reducing the occupied space of the warm food plate and facilitating storage.

[0024] In a possible implementation, the minimum distance from the through hole to the bottom end of the second housing is greater than or equal to 8 millimeters.

[0025] With such a setting, there is a certain distance from the through hole to the bottom end of the second housing. When using the warm food plate, if there is some water on the table, it will not enter the interior of the accommodation cavity through the through hole, ensuring the normal use of the warm food plate and improving the safety performance of the warm food plate.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0051] The hot plate will be described in detail below with reference to the accompanying drawings.

[0052] Figure 1 It is a schematic structural diagram of a hot plate provided by an embodiment of the present utility model. Figure 2 It is provided by an embodiment of the present utility model Figure 1 A sectional view of the hot plate shown in the A-A direction.

[0053] It should be noted that in the embodiments of the present application, for the convenience of description, the thickness direction of the hot plate is taken as the z direction, the length direction of the hot plate is taken as the x direction, and the width direction of the hot plate is taken as the y direction.

[0054] As Figure 1 shown, an embodiment of the present utility model provides a hot plate 100, which may include a cutting board body 10, a first housing 21 and a second housing 22. The first housing 21 and the second housing 22 are provided at one end of the cutting board body 10 in the length direction (x direction), and both the first housing 21 and the second housing 22 extend along the width direction (y direction) of the cutting board body 10.

[0055] It should be noted that in this way, during use, the first housing 21 and the second housing 22 can be provided at one end of the cutting board body 10, which is convenient for use.

[0056] Exemplarily, as Figure 2 shown, on the top surface of the first housing 21, that is, the surface of the first housing 21 facing away from the second housing 22, a control panel 211 may be provided, and the control panel 211 may be electrically connected to the circuit board 30. In this way, the hot plate 100 can be controlled through the control panel 211.

[0057] In a possible implementation, adjustment buttons, switch buttons, and a display screen (not shown in the figure) can be provided on the control panel 211. The operation of the warming dish board 100 is controlled through the adjustment buttons and the switch buttons, and the temperature of the dish board body 10 is displayed through the display screen, so as to facilitate the user to adjust the temperature according to their own preferences and improve the user experience.

[0058] It should be noted that in the embodiments of the present application, the specific structure of the control panel 211 is not further limited.

[0059] Continue to refer to Figure 1 As shown, the dish board body 10 can be in a plate-like structure. Among them, the top surface of the dish board body 10 is configured as the use surface 12, and the use surface 12 is used for placing food. The bottom surface of the dish board body 10 is configured as the support surface of the dish board body 10, and the support surface is used for placing on the table to support the dish board body 10.

[0060] In this way, when in use, the warming dish board 100 can be placed on the table, with the support surface facing the table and the use surface 12 facing away from the table. Food, utensils, etc. can be placed on the use surface 12 of the dish board body 10, so that the warming dish board 100 heats the food located on the use surface 12, preventing the food from getting cold over time when the user is dining, and enabling the food to remain warm throughout the dining process, thus improving the user experience.

[0061] Exemplarily, wiring ports are provided on the first housing 21 and the second housing 22, and the wiring ports are connected to the power supply through a plug 200. The circuit board 30 can be powered on through this wiring port, so that the warming dish board 100 has a heating function.

[0062] Figure 3 This is the Figure 2 Enlarged schematic view of part B of the warming dish board 100 provided by the embodiment of the present utility model.

[0063] As Figure 3 As shown, in the thickness direction of the dish board body 10, the first housing 21 and the second housing 22 are arranged opposite to each other, and the first housing 21 is located at the top of the second housing 22. One end of the dish board body 10 is clamped between the first housing 21 and the second housing 22, and an accommodation cavity 50 is formed among the first housing 21, the second housing 22, and the dish board body 10. A circuit board 30 is arranged in the accommodation cavity 50, a heating element is arranged in the dish board body 10, the circuit board 30 is electrically connected to the heating element, and the circuit board 30 is used to control the heating element to heat the dish board body 10. An exhaust pipe 40 is also arranged in the accommodation cavity 50, a through hole 221 is provided on the first housing 21 or the second housing 22, one end of the exhaust pipe 40 is located in the accommodation cavity 50, and the other end is communicated with the through hole 221.

[0064] In the warming plate 100 according to the embodiment of the present application, by arranging a heating body inside the plate body 10, the warming plate 100 can have a heating function, and thus when in use, the food placed on the plate body 10 can be heated to prevent the food from getting cold. By arranging the first housing 21 and the second housing 22 and clamping the plate body 10 between the first housing 21 and the second housing 22, the plate body 10 can be fixed, and installation positions can also be provided for the circuit board 30, the exhaust pipe 40, etc. By arranging the exhaust pipe 40, the accommodation cavity 50 formed between the first housing 21, the second housing 22 and the plate body 10 can be exhausted, preventing the moisture in the accommodation cavity 50 from causing a short circuit between the components on the circuit board 30, and thus extending the service life of the warming plate 100.

[0065] It should be noted that, Figure 3 The structure shown in is the structure with the through hole 221 arranged on the second housing 22. Of course, in some embodiments, the through hole 221 can also be arranged on the first housing 21. In the embodiment of the present application, the arrangement position of the through hole 221 is not further limited.

[0066] Exemplarily, the first housing 21 and the second housing 22 are detachably connected. For example, the first housing 21 and the second housing 22 can be in plug-in fit, and the first housing 21 and the second housing 22 can be in snap-fit connection. In the embodiment of the present application, the connection manner between the first housing 21 and the second housing 22 is not further limited.

[0067] Such as Figure 3 As shown, the end of the exhaust pipe 40 facing away from the through hole 221 is located on the side of the circuit board 30 facing away from the second housing 22. Among them, in the thickness direction of the plate body 10, the distance from the end of the exhaust pipe 40 facing away from the through hole 221 to the bottom end of the second housing 22 is greater than the distance from the through hole 221 to the bottom end of the second housing 22.

[0068] With such an arrangement, one end of the exhaust pipe 40 can be arranged close to the circuit board 30, which can facilitate the discharge of the moisture near the circuit board 30, and thus improve the safety performance of the warming plate 100. By making the distance from the end of the exhaust pipe 40 facing away from the through hole 221 to the bottom end of the second housing 22 greater than the distance from the through hole 221 to the bottom end of the second housing 22, the moisture condensed in the exhaust pipe 40 can be conveniently discharged.

[0069] In a possible implementation manner, a one-way valve 223 is arranged in the through hole 221. Among them, the one-way valve 223 is used to control the fluid to flow out from the exhaust pipe 40 to the outside of the through hole 221.

[0070] It should be noted that the one-way valve 223 is a valve that allows fluid (liquid or gas) to flow in only one direction. Its main function is to prevent fluid from flowing back and protect pipelines, pumps and other equipment from damage.

[0071] The one-way valve 223 in the embodiment of the present application is used to prevent the fluid from flowing back from the through hole 221 into the accommodating chamber 50. By arranging the one-way valve 223 in the through hole 221, the fluid (liquid, gas or water vapor, etc.) in the exhaust pipe 40 can be discharged from the through hole 221 in one direction, preventing the fluid outside the warming plate 100 from entering the accommodating chamber 50 through the through hole 221, especially preventing the liquid from entering the accommodating chamber 50 and causing a short circuit between components on the circuit board 30, thereby affecting the use of the warming plate 100.

[0072] In the embodiment of the present application, the one-way valve 223 can be disposed in the through hole 221. When the through hole includes a tubular wall 222, the one-way valve 223 can also be disposed in the tubular wall 222. Of course, in some embodiments, the one-way valve 223 can also be disposed in the exhaust pipe 40. In the embodiment of the present application, the location of the one-way valve 223 is not further limited, as long as the backflow of the fluid can be prevented.

[0073] like Figure 4 As shown, the first shell 21, the second shell 22, the chopping board body 10 and the circuit board 30 are all arranged in the horizontal direction, and one end of the chopping board body 10 is clamped between the first shell 21 and the second shell 22, the circuit board 30 is arranged between the first shell 21 and the second shell 22, and the circuit board 30 is fixed between the first shell 21 and the second shell 22.

[0074] With such arrangement, the circuit board 30 can be fixed between the first shell 21 and the second shell 22 so as to be electrically connected to the heating body inside the cutting board body 10, so that the cutting board body 10 of the warm cutting board 100 has a heating function.

[0075] In one possible implementation, Figure 5 As shown, a slotted structure 31 is provided on the circuit board 30 , and one end of the exhaust pipe 40 away from the through hole 221 is located in the slotted structure 31 . The slotted structure 31 is used to limit the radial movement of the exhaust pipe 40 .

[0076] By providing a slotted structure 31 on the circuit board 30 , the exhaust pipe 40 can be fixed on the circuit board 30 , and one end of the exhaust pipe 40 is always located near the circuit board 30 , thereby removing moisture near the circuit board 30 and improving the safety performance of the food warming board 100 .

[0077] Exemplarily, the slotted structure 31 can be a U-shaped structure with one end open, or a circular hole structure, and of course, it can also be a structure of other shapes. In the embodiments of the present application, the specific shape of the slotted structure 31 is not further limited.

[0078] It should be noted that during assembly, one end of the exhaust pipe 40 can be placed in the slotted structure 31 so that one end of the exhaust pipe 40 is defined within the slotted structure 31. This can reduce the assembly difficulty and thus increase the production cost.

[0079] Of course, in some embodiments, the exhaust pipe 40 can also be snap-fitted with the slotted structure 31, so that the connection between the exhaust pipe 40 and the circuit board 30 is stable, preventing the separation between the exhaust pipe 40 and the circuit board 30 during use and affecting the exhaust effect.

[0080] In a possible implementation manner, a tubular wall 222 is provided at one end of the through hole 221 facing the accommodating cavity 50, and the exhaust pipe 40 is inserted and cooperated with the tubular wall 222.

[0081] With such a setting, it is convenient to fix the exhaust pipe 40, reduce the assembly difficulty, and thus save the assembly cost.

[0082] It should be noted that in the embodiments of the present application, the specific structure of the tubular wall 222 is not further limited.

[0083] In some embodiments, the structure of the through hole 221 can be an inclined structure. For example, in the x direction, it gradually slopes downward towards the direction close to the support surface, which can facilitate the drainage of moisture in the exhaust pipe 40.

[0084] Of course, in some embodiments, the structure of the through hole 221 can be a hole structure provided on the second housing 22, and the exhaust pipe 40 can be inserted into the hole structure to communicate the exhaust pipe 40 with the through hole 221. Or, the end of the exhaust pipe 40 is bonded to the through hole 221 to communicate the exhaust pipe 40 with the through hole 221. In the embodiments of the present application, the specific structure of the through hole 221 is not further limited.

[0085] Exemplarily, the through hole 221 can be provided on the side wall of the second housing 22 or on the bottom wall of the second housing 22. In the embodiments of the present application, the setting position of the through hole 221 is not further limited.

[0086] In a possible implementation manner, the number of exhaust pipes 40 can be multiple. Among them, a plurality of through holes 221 are provided on the first housing 21 or the second housing 22, and one exhaust pipe 40 corresponds to one through hole 221. The plurality of exhaust pipes 40 are arranged at intervals along the width direction of the warming plate 100. The width direction is perpendicular to the thickness direction of the chopping board body 10.

[0087] With such a setting, a plurality of exhaust channels can be included in the accommodation cavity 50, improving the exhaust performance of the accommodation cavity 50 to prevent short circuits between components on the circuit board 30 due to moisture in the accommodation cavity 50, thereby extending the service life of the warm food plate 100.

[0088] In a possible implementation, the exhaust pipe 40 is a silicone hose.

[0089] With such a setting, the exhaust pipe 40 can be a soft structure, which is convenient to avoid some components by bending during installation, thereby reducing the assembly difficulty.

[0090] It should be noted that the silicone material tube can be bent arbitrarily without blocking the exhaust pipe 40. Therefore, by setting the exhaust pipe 40 as a silicone hose, the assembly difficulty can be reduced.

[0091] Of course, in some other embodiments, the exhaust pipe 40 can also be set as a hose structure of other materials, such as a rubber tube, etc. Or, the exhaust pipe 40 can also be set as a rigid pipe structure with a bending structure. In the embodiments of the present application, the specific structure of the exhaust pipe 40 is not further limited.

[0092] In a possible implementation, support feet 11 are provided at the bottom of the chopping board body 10, and a plurality of support feet 11 are spaced apart and distributed at the bottom of the chopping board body 10.

[0093] By providing the support feet 11, the chopping board body 10 can be conveniently supported. By spacing the plurality of support feet 11, gaps can be formed between the plurality of support members. In this way, when the chopping board body 10 is working, heat dissipation can be facilitated from below the chopping board body 10, preventing the heat below the chopping board body 10 from being unable to dissipate, resulting in overheating below the chopping board body 10 and easily scalding the user.

[0094] In the embodiments of the present application, the number of the support feet 11 is not further limited.

[0095] In a possible implementation, as Figure 4 shown, the exhaust pipe 40 includes at least one bending portion 41. Among them, the bending portion 41 is used to change the direction of the exhaust pipe 40.

[0096] With such a setting, the extending direction of the exhaust pipe 40 can be changed, so that some components can be avoided during assembly, reducing the assembly difficulty.

[0097] Exemplarily, the exhaust pipe 40 can include one bending portion 41, two bending portions 41 or a plurality of bending portions 41. In the embodiments of the present application, the number of the bending portions 41 is not further limited.

[0098] In a possible implementation, the cutting board body 10 is a silicone cutting board body 10.

[0099] By setting the cutting board body 10 as a silicone cutting board body 10, the cutting board body 10 can be made of a soft structure, which can be folded or rolled up during storage, thus reducing the occupied space of the warming tray 100 and facilitating storage.

[0100] It should be noted that in some embodiments, the cutting board body 10 can also be set as a structure of other materials. In the embodiments of the present application, the specific material of the cutting board body 10 is not further limited.

[0101] In a possible implementation, a support structure is provided on the side of the second housing 22 facing away from the first housing 21, and the bottom surface of the support structure is configured as the support surface of the warming tray 100. Among them, the minimum distance from the through hole 221 to the bottom end of the second housing 22 is greater than or equal to 8 millimeters.

[0102] Exemplarily, the minimum distance from the through hole 221 to the bottom end of the second housing 22 can be 8 millimeters, 9 millimeters, 10 millimeters, etc. In the embodiments of the present application, the minimum distance from the through hole 221 to the bottom end of the second housing 22 is not further limited.

[0103] With such a setting, there can be a certain distance from the through hole 221 to the bottom end of the second housing 22. In this way, when the warming tray 100 is used and there is some water on the table, the water will not enter the interior of the accommodating cavity 50 through the through hole 221, so as to ensure the normal use of the warming tray 100 and improve the safety performance of the warming tray 100.
