Description

Technical Field

[0001] This utility model relates to the field of dining table technology, and in particular to a heating table capable of achieving zoned heating. Background Technology

[0002] In traditional dining tables, food is typically served after cooking in the kitchen, and the table itself does not provide heating functionality. This means that food cools down shortly after being served, especially in cold environments, which can affect its taste and quality. Although some dining tables with heating functions exist on the market, they usually only provide overall heating and lack the ability to cater to the specific heating needs of different foods.

[0003] Currently, patent CN215076380U discloses a tabletop heat-generating and heat-insulating dining table. It mainly includes a tempered glass tabletop and a table frame body located below the tempered glass tabletop. Four fixed legs are hinged to the lower side of the table frame body. A groove is cut between the tempered glass tabletop and the table frame body, and a resistance heating wire is laid in the groove. A power supply temperature control module is installed on one side of the table frame body to cooperate with the resistance heating wire. The resistance heating wire, placed between the tempered glass tabletop and the table frame body, can conduct the heat generated by the resistance heating wire to the surface of the tempered glass tabletop, thereby keeping the food on the tempered glass tabletop warm. The power supply temperature control module allows for precise setting of the heating area and temperature of the resistance heating wire on the tempered glass tabletop, thus improving the practicality of the heat-insulating dining table.

[0004] However, in practical applications, because the tabletop is circular and made of tempered glass, the heating zones are not clearly defined, and the glass is prone to cracking due to heat during prolonged heating, posing a safety hazard. In addition, the table cannot provide differentiated heating for different food cooking and eating needs, meaning that it cannot effectively control the temperature of different areas when heating.

[0031] The following is in conjunction with the appendix Figure 1-5 The present invention provides a more detailed description of an embodiment of a dual-zone heating table.

[0032] A dual-zone heating table, such as Figure 1 , 2 As shown, the device includes a desktop 1, a heating element 2, and a temperature control element 3. The desktop 1 is a rectangular integrated structure and is divided into two temperature-adjustable heating areas: an inner heating area 11 and an outer heating area 12. The inner heating area 11 is located near the center of the desktop 1, and the outer heating area 12 is located near the perimeter of the desktop 1. The heating element 2 generates heat to heat the desktop 1 and includes a first heating element 21 and a second heating element 22, which are respectively located below the inner heating area 11 and the outer heating area 12. The temperature control element 3 controls the temperature of the inner heating area 11 and the outer heating area 12. The temperature control element 3 is located at the bottom of the desktop 1 and is electrically connected to the heating element 2.

[0033] Specifically, the integrated desktop 1 is not only more aesthetically pleasing but also reduces complex assembly steps. Furthermore, the rectangular structure of the desktop 1 makes the heating zones more distinct, and the setup of the heating components 2 is simpler and more convenient. During zone control, the temperature control component 3 can simultaneously control the first heating element 21 and the second heating element 22 to heat synchronously, allowing the outer heating area 12 and the inner heating area 11 to heat up simultaneously. The temperature control component 3 can also independently control either the first heating element 21 or the second heating element 22, allowing it to select the appropriate control mode according to actual application needs. In addition, the temperatures of both the outer heating area 12 and the inner heating area 11 can be customized to meet the differentiated heating requirements of different foods.

[0034] In this embodiment, as Figure 2 As shown, the temperature setting range of the inner heating area 11 of the desktop 1 is 60-100℃, and the temperature setting range of the outer heating area 12 is 30-60℃.

[0035] Specifically, the purpose of setting the temperature of the inner heating zone 11 higher than that of the outer heating zone 12 is to facilitate heating or keeping food warm, while the lower temperature of the outer heating zone 12 is used to heat cold dishes or other dishes that do not require high temperatures. At the same time, the lower temperature of the outer heating zone 12 can prevent users from being burned. The temperature range of the inner heating zone 11 is 60-100℃, at which temperature it can heat food for a long time or be used directly as a hot pot table. The temperature range of the outer heating zone 12 is 30-60℃, which can provide users with hand warming function and keep some dishes warm.

[0036] In this embodiment, as Figure 1 As shown, the temperature control component 3 includes a temperature sensor 31, a temperature controller 32, and a control panel 33. The temperature sensor 31 is used to detect the temperature of each heating zone; the temperature controller 32 is used to adjust the heating temperature of the first heating element 21 and the second heating element 22; the control panel 33 is used to set and display the temperature; the temperature sensor 31, the temperature controller 32, and the control panel 33 are electrically connected.

[0037] Specifically, before use, users can set the temperatures of the inner heating zone 11 and the outer heating zone 12 through the control panel 33; for example, users can set the temperature of the inner heating zone 11 to 80°C to keep food warm or cook food that requires a higher temperature, and set the temperature of the outer heating zone 12 to 40°C to keep the food warm or provide a warm dining environment.

[0038] It is worth mentioning that when the user places food in the corresponding heating area, the temperature control component 3 will automatically adjust the power of the heating component 2 according to the set temperature to maintain the required temperature. If the temperature is lower than the set value, the heating component 2 will increase the power output; if the temperature is higher than the set value, the heating component 2 will reduce the power output or temporarily turn off; and the thermostat 32 can limit the maximum temperature of the inner heating area 11 to 100°C.

[0039] In this embodiment, the first heating element 21 is a resistance heating wire or a ceramic heater.

[0040] Specifically, the use of resistance heating wire can automatically rotate to generate heat in the inner heating area 11, making the heating uniform and improving the heating effect, while the use of ceramic heater can save costs and increase its applicability.

[0041] In this embodiment, the second heating element 22 is a carbon fiber heating wire or a quartz tube heater.

[0042] Specifically, the use of carbon fiber heating wire or quartz tube heater can quickly respond to the heating temperature, providing the necessary conditions for the rapid heating of the external heating area 12. At the same time, both carbon fiber heating wire and quartz tube heater can control the heating temperature so that it matches the temperature of the external heating area 12.

[0043] In this embodiment, a mounting frame 4 is provided below the desktop 1, and the desktop 1 is detachably connected to the mounting frame 4. Support legs 5 are hinged at the four corners of the mounting frame 4. A heat insulation plate 6 is provided between the desktop 1 and the mounting frame 4. The heat insulation plate 6 is fixed to the mounting frame 4, and a space for installing the first heating element 21 and the second heating element 22 is formed between the heat insulation plate 6 and the desktop 1.

[0044] Specifically, both the mounting frame 4 and the support legs 5 are made of metal, which improves the stability of the heating table and extends its service life. The mounting frame 4 and the support legs 5 are detachably connected; the support legs 5 are hinged to the four corners of the mounting frame 4 via hinges. With the hinges, the support legs 5 can be folded inside the mounting frame 4 for easy storage and space saving. At the bottom of the mounting frame 4, a heat insulation plate 6 is fixed with screws. The heat insulation plate 6 effectively isolates the heat dissipated by the heating element 2, concentrating the heat on the tabletop 1 and preventing accidental burns from users touching the heating element 2 while dining.

[0045] To further facilitate handling and disassembly, the desktop 1 and the mounting frame 4 are connected by a snap-fit ​​mechanism. Specifically, the mounting frame 4 has a slot, and a corresponding locking block is located on the bottom of the desktop 1 at the slot position. The locking block engages with the slot, allowing the desktop 1 to be quickly installed onto the mounting frame 4.

[0046] In this embodiment, the desktop 1 is made of a thermally conductive material, such as metal, ceramic, or slab.

[0047] Specifically, different materials have different thermal conductivity. Therefore, users can choose the appropriate material according to their personal preferences and needs. However, it is worth noting that the desktop 1 material in this invention does not use plastic or wood materials. These materials have poor thermal conductivity and are not heat-resistant. When the desktop 1 is made of these two materials, the heating effect will be poor when the heating temperature is too high, and the desktop 1 will be easily damaged.

[0048] The assembly process of the dual-zone heating table in this utility model is as follows:

[0049] During installation, the heating components 2 are first installed below the inner heating area 11 and outer heating area 12 of the tabletop 1. These heating components 2 can be connected to the tabletop 1 by welding, bonding, or mechanical fixing. Ensure that the heating components 2 are evenly distributed and in good contact with the tabletop 1 to improve heat transfer efficiency. Next, install the temperature control device. Temperature sensors 31 are installed below each heating area, close to the heating components 2. The control panel 33 is installed on one side of the mounting bracket 4 or on the support leg 5 of the heating table for easy user operation. Simultaneously, connect the heating components 2 and the temperature control component 3 to the power cord to ensure that power is supplied to all parts of the heating table.

[0050] Through the above steps, the dual-zone heating table can be put into use. Users can flexibly adjust the temperature settings according to the cooking and eating needs of the food to achieve differentiated heating of the food. In addition, the dual-zone heating table of this utility model can also provide personalized heating solutions according to the user's usage habits and preferences, thereby improving the dining experience.

[0051] This utility model of a dual-zone heating table offers users a brand-new dining experience through its simple structure and ease of operation. It can not only meet the heating needs of different foods, but also provide customized heating services according to the user's personal preferences. This design not only improves the practicality of the table, but also enhances its aesthetics and comfort, and has broad application prospects.

[0052] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
