Description

Technical Field

[0001] This utility model demonstrates a food warming board, belonging to the technical field of food warming boards. Background Technology

[0002] With the development and promotion of the small household appliance industry, cutting boards have gradually become an essential household item because they have advantages such as rapid and even heating, long-lasting heat retention, easy cleaning, good safety and beautiful appearance.

[0003] Existing food warmers typically include a shell, a heating module installed inside the shell, and a panel mounted on the shell. The shell also houses a main control board electrically connected to the heating module. During use, the main control board controls the heating module to generate heat, creating a heating area on the panel to heat and keep the food warm. However, existing food warmers only have a single heating module, heating the entire surface of the warmer uniformly. The heating module provides the same amount of heat to the entire panel. When multiple foods with different heating requirements are placed on the warmer simultaneously, it can usually only meet the heating needs of one type of food, not all of them. This may lead to a loss of texture in some foods. Furthermore, regardless of the amount of food on the warmer, the heating module always heats the entire panel. Even if only one food is placed on the warmer, the heating module will still heat the entire panel, affecting the heating efficiency and wasting a significant amount of heat, thus reducing the heat utilization rate of the heating module. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing food warmers cannot achieve zoned heating to simultaneously meet the heating needs of different foods. To this end, a food warmer is provided that, by setting multiple independently operating heating modules, achieves zoned heating to simultaneously meet the heating needs of different foods.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A food warmer includes a housing and a main control board disposed within the housing. The housing is internally divided into several placement cavities, and several heating modules are installed within the housing. Each placement cavity contains a heating module, and each placement cavity is covered with a panel. Each heating module is independently connected to and controlled by the main control board. A pressure sensor is installed on the upper surface of the heating module, and the pressure sensor abuts against the bottom surface of the panel. The outer periphery and / or bottom surface of the panel is filled with elastic waterproof adhesive to keep the placement cavity sealed.

[0007] The beneficial effects of using this utility model are:

[0008] The interior of the housing described in this invention is divided into several placement cavities, each equipped with an independently operating heating module. Each cavity is covered by a separate panel. When multiple foods are placed on the warming plate, foods with different heating requirements can be placed on the panels of different placement cavities. The heating modules then heat and keep the food on the plates warm. The main control board can control the heat output of the corresponding heating modules based on the food's needs, enabling differentiated heating of the warming plate and ensuring that more foods maintain a good eating texture. Furthermore, the warming plate can activate one or more heating modules depending on the quantity of food, maximizing the utilization of heat and improving the heat efficiency of the warming plate. Secondly, each heating module is equipped with a pressure sensor. When the pressure sensor detects whether food is placed on the panel, the main control board activates the corresponding heating module. This prevents heating modules from continuing to heat even when there is no food on some placement cavities, reducing unnecessary energy loss and achieving energy-saving effects.

[0009] Additionally, the outer periphery or bottom surface of the panel is filled with elastic waterproof adhesive. This adhesive seals the gap between the panel and the placement cavity, keeping the entire placement cavity sealed and preventing liquid from seeping into it, thus reducing the possibility of damage to the heating module due to liquid. Furthermore, the waterproof adhesive is bonded between the placement cavity and the panel. Because the adhesive is elastic, the panel can move slightly relative to the placement cavity. When food is placed on the panel, its weight causes the panel to sink, making the fit between the panel and the pressure sensor tighter. This allows for more accurate feedback of pressure changes on the panel to the pressure sensor, resulting in more accurate and reliable pressure sensor readings and improved sensitivity.

[0010] Preferably, a baffle is provided between two adjacent placement cavities within the housing, with the baffle surrounding and forming the placement cavity; or the baffle and the edge of the housing surround and form the placement cavity. Using the aforementioned technical solution, the baffle can separate all placement cavities, allowing each cavity to have greater independence and reducing the possibility of mutual interference between adjacent placement cavities. In addition, the baffle also provides heat insulation, reducing heat transfer between adjacent placement cavities, making the heat generated in each placement cavity more precise, providing accurate heat requirements for food, maintaining optimal taste, and significantly improving the user experience.

[0011] Preferably, the surface of the panel is higher than the top surface of the retaining rib and the top surface of the shell edge. Using the aforementioned technical solution, the overall appearance of all panels can be more complete, improving the aesthetics of the food warming board. Alternatively, keeping the upper surface of the food warming board as flat as possible allows some food to be placed between adjacent panels when there is a large amount of food to be placed, providing more space for food and increasing the utilization rate of the upper surface of the food warming board, enabling it to hold more food.

[0012] Preferably, the panel is embedded in the placement cavity, and the baffles limit the outer periphery of the panel. A support platform is provided inside the placement cavity, and the panel is placed on the support platform and covers the placement cavity. Using the aforementioned technical solution, the baffles can limit the panel, making the installation and positioning of the panel simpler and faster. In addition, the baffles can isolate adjacent panels, reducing the possibility of interference between adjacent panels affecting the pressure sensor, giving each panel greater independence and ensuring accurate detection by the pressure sensor.

[0013] Preferably, the waterproof adhesive is filled between the panel and the reinforcing rib, and between the panel and the edge of the housing; and / or, the waterproof adhesive is filled between the panel and the support platform. By employing the aforementioned technical solution, filling the space between the panel and the reinforcing rib allows the panel to maintain a tight fit with the support platform, thereby ensuring all panels remain as flat as possible. Furthermore, the waterproof adhesive fills the gap between the panel and the reinforcing rib, preventing food residue or soup from seeping into the narrow crevices, thus facilitating cleaning of the warming board. Alternatively, filling the space between the panel and the support platform reduces the distance between the panel and the reinforcing rib, thereby reducing the distance between adjacent panels, improving the overall integrity of the warming board, and also reducing the direct exposure of the waterproof adhesive to the user, thus enhancing the aesthetics of the warming board.

[0014] Preferably, the support platform is laid along the edge of the placement cavity and surrounds the outer periphery of the heating module. Using the aforementioned technical solution, the support platform can limit the movement of the heating module, reducing its sway and making its positioning simpler and more convenient. Furthermore, laying the support platform along the edge of the placement cavity increases its length, thereby increasing the contact area between the support platform and the panel, providing more stable support for the panel.

[0015] Preferably, the panel is placed on the retaining rib, and the retaining rib provides support for the panel.

[0016] Preferably, the warming plate also includes a base, and a turntable is provided between the base and the shell. The turntable drives the shell to rotate relative to the base. Using the aforementioned technical solution, the turntable can drive the warming plate to rotate. When there is a lot of food, the rotation of the warming plate allows diners to easily taste each food item on the plate, providing convenience and a better dining experience.

[0017] Preferably, the main control board is installed in one of the placement chambers, with a portion of the sidewall of the placement chamber forming the edge of the housing. The main control board is located on the side of the placement chamber closest to the edge of the housing, and an operating area is formed on the panel of the placement chamber. By adopting the aforementioned technical solution, the main control board is close to the edge of the warming plate's housing, thereby reducing the distance between the main control board and the diner. This allows the diner to easily observe and operate the main control board, making the use and adjustment of the warming plate simpler and more convenient, and improving the user experience.

[0018] Preferably, the shell is circular, and the placement cavity includes a circular placement cavity in the center of the shell and fan-shaped placement cavities distributed circumferentially along the circular placement cavity. Using the aforementioned technical solution, the fan-shaped placement cavities have a larger area the closer they are to the edge of the warming plate, thus allowing more food to be placed closer to the diners. This allows diners to enjoy more food while seated, without frequently standing up and sitting down, improving the dining experience. Furthermore, the turntable increases the range of food that diners can pick up, thereby increasing the diameter of the warming plate and making it suitable for more diners and more food quantities, thus expanding the applicability of the warming plate.

However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise expressly defined.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] like Figures 1 to 5As shown in the figure, this embodiment demonstrates a food warmer, including a housing 1 and a main control board 3 disposed within the housing 1. The interior of the housing 1 is divided into several placement cavities 11, and several heating modules 12 are installed inside the housing 1. Each placement cavity 11 is provided with a heating module 12, and each placement cavity 11 is covered with a panel 2. Each heating module 12 is independently connected to and controlled by the main control board 3. A pressure sensor 13 is installed on the upper surface of the heating module 12, and the pressure sensor 13 abuts against the bottom surface of the panel 2. The outer periphery of the panel 2 is filled with elastic waterproof adhesive to keep the placement cavity 11 sealed.

[0032] In this embodiment, the interior of the housing 1 is divided into multiple placement cavities 11, and an independently operating heating module 12 is installed in each placement cavity 11. Each placement cavity 11 is covered by a separate panel 2. Each heating module 12 is connected to the main control board 3 through a separate circuit, so that the main control board 3 can control each heating module 12 to turn on and heat up independently, reducing the mutual influence between the heating modules 12. When there are multiple foods on the warming plate, foods with different heating requirements can be placed on the panels 2 of different placement cavities 11, and then the heating modules 12 heat and keep the food on the panels 2 warm. The main control board 3 can control the heat output of the corresponding heating module 12 according to the needs of the food, so as to realize differentiated heating of the warming plate, thereby allowing more foods to maintain a better taste. In addition, the warming plate can also turn on one or more heating modules 12 according to the quantity of food, so that the heat generated by the heating modules 12 can be fully utilized, improving the heat utilization rate of the warming plate.

[0033] Secondly, the warming board can activate different numbers of heating modules 12 depending on the number of diners. For example, when there are many diners, they usually sit around the warming board, and the food is distributed as evenly as possible. In this case, all the heating modules 12 on the warming board can be activated to meet the heating needs of all the food. When there is only one or a few diners, they can sit on one side of the warming board, and the food can be placed on the side of the warming board closest to the diners. In this case, only one or two heating modules 12 need to be activated to meet the heating needs of the food. Other heating modules 12 away from the diners do not need to be activated, thereby reducing heat loss and achieving energy saving. This embodiment sets up multiple independent heating modules 12 to achieve zoned heating, thereby meeting the heating needs of different foods. At the same time, different numbers of heating modules 12 can be activated according to the number of diners or the amount of food, thereby improving the utilization rate of the heat generated by the warming board and making the use of the warming board more flexible and versatile.

[0034] Additionally, a pressure sensor 13 is installed on the heating module 12. The pressure sensor 13 can detect whether there is food on the panel 2. The main control board 3 has a heating threshold. When the pressure sensor 13 detects food on the panel 2, it transmits the pressure change on the panel 2 to the main control board 3 through a signal value. The main control board 3 compares the signal value with the heating threshold. When the signal value is greater than the heating threshold, the main control board 3 can unlock the restriction on the heating module 12 corresponding to the pressure sensor 13. At this time, the user can control the corresponding heating module 12 to start heating. This can avoid the phenomenon that the heating module 12 is still heating when there is no food on the panel 2 of some placement cavities 11, which can reduce unnecessary energy consumption and achieve energy saving.

[0035] In this embodiment, an elastic waterproof adhesive is used to fill the space between the panel 2 and the placement cavity 11. This adhesive serves two purposes: firstly, it bonds the panel 2 to the placement cavity 11, securing the panel 2; secondly, it seals the gap between the panel 2 and the placement cavity 11, keeping the placement cavity 11 completely sealed. This prevents liquid from seeping into the placement cavity 11, reducing the possibility of damage to the heating module 12 due to liquid. Furthermore, the waterproof adhesive is bonded between the placement cavity 11 and the panel 2. Because the adhesive is elastic, the panel 2 can move slightly relative to the placement cavity 11. When food is placed on the panel 2, its weight causes the panel 2 to sink, resulting in a tighter fit between the panel 2 and the pressure sensor 13. Changes in pressure on the panel 2 can be more accurately fed back to the pressure sensor 13, making the detection results of the pressure sensor 13 more accurate and reliable, and also improving the sensitivity of the pressure sensor 13.

[0036] like Figure 2 and Figure 3 As shown in the figure, in this embodiment, a baffle 14 is provided between two adjacent placement cavities 11 inside the housing 1. The baffle 14 divides the interior of the housing 1 into multiple placement cavities 11. Some placement cavities 11 are formed by the baffle 14, and some placement cavities 11 are formed by the baffle 14 and the edge of the housing 1. Finally, the panel 2 covers each placement cavity to form an independent and sealed chamber. By setting the baffle 14 inside the housing 1 to separate the placement cavities 11, each placement cavity 11 can have a higher degree of independence and reduce the possibility of mutual interference between two adjacent placement cavities 11. In addition, the baffle 14 can also play a role in heat insulation. The baffle 14 can reduce the heat transfer between two adjacent placement cavities 11, making the heat generated by each placement cavity 11 more precise, providing precise heat requirements for food, keeping the food as delicious as possible, and significantly improving the user experience.

[0037] It should be noted that the overall structure of the warming plate in this embodiment is circular. The baffle 14 surrounds a circular placement cavity 111 in the center of the warming plate. Other baffle 14 are distributed radially and extend to the edge of the shell 1, thereby forming multiple fan-shaped placement cavities 112 on the outer periphery of the circular placement cavity 111. The closer the fan-shaped placement cavity 112 is to the edge of the warming plate, the larger its area is, so that more food can be placed. That is, more food can be placed closer to the diners, so that the diners can enjoy more food while sitting without having to stand up and sit down frequently, which can improve the dining experience.

[0038] In addition, the formation of an independent circular placement cavity 111 in the center of the warming plate can effectively reduce heat loss. For example, when there are few diners or little food, the food is usually placed on the edge of the warming plate to make it easier for diners to pick it up. Consequently, the central part of the warming plate is used less frequently than the edge. Therefore, the arrangement of the placement cavity 11 in this embodiment allows the circular placement cavity 111 to only open and generate heat when food is placed on it, thereby reducing the ineffective heat loss in the center of the warming plate. Secondly, the circular placement cavity 111 can reduce the maximum distance between the fan-shaped placement cavity 112 and the diners, allowing diners to pick up food from the entire fan-shaped placement cavity 112 while seated. At the same time, when no food is placed in the circular placement cavity 111, the heating module 12 inside will not generate heat, thereby reducing ineffective heat loss and achieving energy saving.

[0039] It is understandable that in other embodiments, the overall structure of the food warmer can also be square or other structures that match the dining table.

[0040] like Figure 2 and Figure 3 As shown, in this embodiment, a support platform 15 is provided inside the placement cavity 11. After the food warming board is assembled, the panel 2 is embedded into the placement cavity 11 and placed on the support platform 15. The baffle 14 is located on the outer periphery of the panel 2, which can limit the panel 2, making the installation and positioning of the panel 2 simpler and faster. At the same time, it can also avoid the panel 2 interfering with the installation of other panels 2, which helps to improve the assembly efficiency of the panel 2. In addition, the baffle 14 can block two adjacent panels 2, reducing the possibility of mutual interference between two adjacent panels 2 and affecting the pressure sensor 13, so that each panel 2 has higher independence and provides a guarantee for the accurate detection of the pressure sensor 13.

[0041] In this embodiment, the waterproof adhesive is filled between the panel 2 and the retaining rib 14, as well as between the panel 2 and the edge of the housing 1. Filling the panel 2 and the retaining rib 14 with the waterproof adhesive allows the panel 2 to maintain a tight fit with the support platform 15, thereby keeping all panels 2 as flat as possible. In addition, the waterproof adhesive can fill the gap between the panel 2 and the retaining rib 14, thereby preventing food residue or soup from seeping into the narrow gap, so that food residue or soup is all on the upper side of the retaining rib 14, which facilitates the cleaning of the warming board.

[0042] It is understandable that in other embodiments, the waterproof adhesive can also be filled between the panel 2 and the support platform 15, that is, the waterproof adhesive is located between the lower surface of the panel 2 and the upper surface of the support platform 15. The panel 2 and the support platform 15 compress the waterproof adhesive. Since there is no need to fill the waterproof adhesive between the panel 2 and the baffle 14, the distance between the panel 2 and the baffle 14 can be reduced, thereby reducing the distance between two adjacent panels 2, making the overall integrity of the cooking board better. At the same time, it can also reduce the direct exposure of the waterproof adhesive to the user's view, which helps to improve the aesthetics of the cooking board.

[0043] It is understandable that, in other embodiments, the waterproof adhesive may also be filled simultaneously between panel 2 and baffle 14, and between panel 2 and support platform 15.

[0044] It is understandable that in other embodiments, the placement cavity 11 may not have a support platform 15. During the assembly of the warming plate, the panel 2 is placed directly on the baffle 14, and the baffle 14 provides support for the panel 2.

[0045] like Figure 2 and Figure 3As shown, to avoid the baffle 14 obstructing the placement of food, in this embodiment, the surface of the panel 2 is higher than the top surface of the baffle 14 and the top surface of the edge of the shell 1. When the upper surfaces of all panels 2 are basically flush, the overall upper surface of the warming board can have better integrity, which helps to improve the aesthetics of the warming board. In addition, when the top surface of the baffle 14 is lower than the upper surface of the panel 2, a gap will be formed at the baffle 14 on the upper surface of the warming board. Since the width of the baffle 14 is small, food can cross the baffle 14 and remain stable under the support of the two panels 2, so it will not affect the placement of food. When there is a lot of food to be placed, some of the food can be placed in a way that allows for easy placement. The food is placed between two adjacent panels 2, providing more space for food placement and improving the utilization rate of the upper surface of the warming board, allowing more food to be placed on it. However, when the top surface of the baffle 14 is higher than the upper surface of the panel 2, the baffle 14 will form a protrusion on the upper surface of the warming board. Even if the height of the baffle 14 protrusion is small, it will cause the food to be unable to be placed stably, which may cause the soup to spill out and the food to tip over, posing a lot of hidden dangers. Correspondingly, the edge of the shell 1 is lower than the upper surface of the panel 2, which allows the food to be partially detached from the panel 2 during placement, thereby increasing the amount of food that can be placed and improving the utilization rate of the warming board space.

[0046] like Figure 4 and Figure 5 As shown, in this embodiment, the support platform 15 is laid along the edge of the placement cavity 11 and surrounds the outer periphery of the heating module 12. The support platform 15 can limit the heating module 12, reduce the shaking amplitude of the heating module 12, and make the positioning of the heating module 12 simpler and more convenient. In addition, the support platform 15 is laid along the edge of the placement cavity 11, which can increase the length of the support platform 15, thereby increasing the contact area between the support platform 15 and the panel 2, and can provide more stable support for the panel 2.

[0047] like Figure 4 and Figure 5 As shown, in this embodiment, one of the fan-shaped placement cavities 112 of the housing 1 is provided with a mounting cavity 16 for mounting the main control board 3. The mounting cavity 16 is located on the side of the placement cavity 11 near the edge of the housing 1. After the panel 2 is installed on the fan-shaped placement cavity 112, the panel 2 covers the main control board 3. At the same time, an operation area for operating the main control board 3 is formed on the panel 2. The main control board 3 is close to the edge of the housing 1 of the warming plate, which can reduce the distance between the main control board 3 and the diner, so that the diner can easily observe and operate the main control board 3, making the use and adjustment of the warming plate simpler and more convenient, and helping to improve the user experience.

[0048] It should also be noted that, in this embodiment, the fan-shaped placement cavity 112 within the housing 1 containing the main control board 3 may not have a heating module 12. Installing the main control board 3 would occupy a significant amount of space in the placement cavity 11, reducing the area of ​​the heating module 12 and making the cavity irregular. Therefore, installing the heating module 12 would require customization, increasing its manufacturing cost. Furthermore, the heat generated by the heating module 12 during heating would affect the main control board 3. Thus, not installing the heating module 12 in the fan-shaped placement cavity 112 allows the main control board 3 to operate in a better environment, helping to extend its lifespan. Of course, it is understood that in other embodiments, some placement cavities 11 may also be without a heating module 12, such as the circular placement cavity 111 in the center of a less frequently used food warmer.

[0049] The warming plate described in this embodiment also includes a base, and a turntable is provided between the base and the housing 1. The turntable drives the housing 1 to rotate relative to the base, and the turntable can drive the warming plate to rotate. When there is a lot of food, the rotation of the warming plate allows diners to easily taste each food on the warming plate, providing convenience for diners and a good dining experience. In addition, the turntable increases the range of food that diners can pick up, which in turn increases the diameter of the warming plate, so that the warming plate can be used for more diners and more food, thus improving the applicability of the warming plate.

[0050] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
