Description

Technical Field

[0001] The invention patent relates to the field of catering technology, specifically, to a food heating and insulation system. Background Art

[0002] Existing dining tables generally do not have the function of heating or keeping warm the plates on the table. The temperature of the food on the plates on the table drops quickly, which has a great impact on the taste and taste of the food, and the user experience is not good, especially in autumn and winter, when friends usually spend a long time eating together, and the food cools down quickly, which greatly affects the user's dining experience.

[0003] The existing table heating and insulation turntables (CN216602056U as an example) are all electromagnetic cookers and electric ceramic stove heating turntable surfaces. The restaurant plates are placed in the heating and insulation area, and heat is transferred through the limited contact area at the bottom of the plates. In theory, the dishes can be heated, but in actual use, three problems of low heating efficiency are found. First, the table heating and insulation turntable (CN216602056U as an example) has a large power in the central hot pot heating area, and a small power and a large insulation area in the peripheral insulation area, resulting in a low temperature in the insulation area; second, the bottom of the restaurant plate has a small contact area with the turntable heating surface, and the heat received by the plate from the turntable heating area is very limited; third, the main tool for serving dishes in the restaurant is a porcelain bowl, and the porcelain bowl has poor thermal conductivity. The heat transfer efficiency of the porcelain and the insulation board in direct contact is very low, and the ideal heating and insulation effect cannot be achieved.

[0004] Invention patent content

[0005] The purpose of this patent is to provide a food heating and insulation system that can quickly heat the food on the plate placed on the table and keep it in an ideal temperature range, while preventing users from being scalded.

[0006] The embodiment of the present invention is implemented as follows:

[0007] The patent of the present invention provides a dish heating and heat preservation system, a dish heating and heat preservation system comprises: a bottom plate, a panel, an outer circle support bar, an inner circle support bar, a load-bearing support bar, an electric slip ring, a switch, and a heating plate with a temperature controller;

[0008] The panel plate, outer circle support bar, inner circle support bar and load-bearing support bar form an integrated support panel. The electric slip ring can be rotatably hung in the center of the panel or fixed on the restaurant table. The heating plate and switch with built-in temperature controller are fixed on the panel. The base and panel form a dining table turntable.

[0009] There is a hollow area on the panel, in which a heating plate with a built-in temperature controller of matching size is placed to facilitate the placement of dinner plates. An appropriate amount of water or non-toxic liquid is put into the heating plate with a built-in temperature controller in the hollow area; the heated water wraps the dinner plate to transfer heat energy to the dinner plate over a large area, so that the dishes are kept at the set temperature.

[0010] The beneficial effects of a dish heating and heat preservation system provided by the embodiment of the present invention include:

[0011] 1. The plate with the dishes is placed in the heating plate with its own temperature controller. The bottom of the plate is wrapped by the heated water in the heating plate with its own temperature controller, which can quickly transfer heat energy to the plate, heating or keeping the dishes warm, so that users can experience the best taste and flavor of the dishes, and it is also convenient for users to dine together for a long time;

[0012] 2. The heating and insulation turntable is made of materials with poor thermal conductivity such as ceramics, glass or aluminum-plastic panels, which will not cause accidental burns to users;

[0013] 3. The heating and insulation area is located at the edge of the entire turntable, which is convenient for users to dine, and the plate placement area can be designed to be larger and accommodate more plates. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1 and Figure 2 and Figure 3The present invention provides a food heating and heat preservation system, including:

[0022] 2. The panel 6, the outer circular support bar 3, the outer circular support bar 2 and the load-bearing support bar 4 form an integrated panel;

[0023] 3. The bottom plate 1 and the panel 6 form a dining table turntable;

[0024] 4. There are two ways to install the electric slip ring 7. In the first way, the non-rotating end can be fixed on the dining table downward, and the rotating end can be connected to the heating plate 8 with the built-in temperature controller upward. In the second way, the electric slip ring 7 can be suspended in the center of the panel 6 through an axis passing through the center hole of the electric slip ring 7. The power cord of the non-rotating end of the electric slip ring 7 extends out through the lower end of the rotating base of the dining plate. Both of the above methods can ensure that the power cord of the electric slip ring 7 is not entangled when the dining plate rotates; the switch 5 is connected to the power supply of the heating plate 8 with the built-in temperature controller and fixed on the panel 6;
