Generally, in the hot pot that appears on the market warm chopping board, the furnace body that has used as beating the hot pot has still included the setting at furnace body outlying heating element including electromagnetism stove or electric pottery stove for the hot pot warm chopping board is when possessing and beats the hot pot, still can be used to heat the meal of placing on its panel and keep warm, satisfies the demand that the user keeps warm the meal under the weather that temperature is low. However, for many reasons, the function of warming dishes is not usually provided above the panel at the position of the fire pan.

The present invention provides a novel thermal insulation device, such as the hot pot dish warming plate, as shown in fig. 1 to 3, the thermal insulation device comprises:

the panel 1 is provided with a middle heating component 11 and a peripheral heating component 12 arranged around the periphery of the middle heating component 11, and the middle heating component 11 and the peripheral heating component 12 can work independently;

the stove body 3 is arranged below the middle heating component 11, and a heating component 31 for heating a pot to be cooked carried above the panel 1 is arranged in the stove body 3;

and the key display board 4 is used for operating and controlling the middle heating component 11 or the peripheral heating component 12 to carry out heat preservation operation or controlling the oven body 3 to carry out cooking.

It should be noted that, regarding the matching relationship between the panel 1 and the chassis 2, the panel 1 is covered on the chassis 2, where the covering refers to the panel 1 being disposed above the chassis 2, and the panel 1 and the chassis forming the whole body or shell of the thermal insulation device, in the actual production operation, the mounting and fixing manner of adhering the panel 1 to the chassis 2 is often adopted. In addition, regarding the manner of mounting the key display panel 4, the key display panel 4 may be disposed on the chassis 2 or adhered to the back surface of the panel 1 by a bracket. In general, the key display panel 4 is controlled by touching or the like above the panel 1 to perform a function operation of the heat retaining device.

Therefore, the novel heat preservation device has the functions of cooking and heat preservation. The middle heating component as a heat preservation heating element is additionally arranged above the cooking oven body, so that the heat preservation device has a heating and heat preservation function at the periphery of the panel, and has a heat preservation effect at the center, therefore, compared with other panels with the same size on the market, the heat preservation device has the advantages that the heat preservation heating area of the whole panel is wider, dishes loaded on the panel are heated, the heat preservation utilization rate and efficiency are higher, and the user satisfaction degree is higher.

It should be noted that, in the heat retaining device of the present invention, the heating element 31 may be selected as an electromagnetic coil disk. According to the working principle of an electromagnetic coil panel (an electromagnetic oven), the heating principle of magnetic field induction current (also called eddy current) is adopted, and the electromagnetic coil panel can emit magnetic lines of force which can penetrate through the panel 1 under the working state of the oven body 3 so as to heat a pot to be cooked. The heat preservation device is particularly suitable for an electromagnetic oven type hot pot dish warming plate, and when the oven body 3 works, magnetic lines of force are sent out to penetrate through the middle heating component 11 and the panel 1 to heat a pot to be cooked placed on the surface of the panel 1. And, when the electromagnetic coil panel of the furnace body 3 works, the middle heating component 11 does not work. Therefore, the electromagnetic coil panel and the middle heating component 11 which are arranged up and down can respectively realize different functions, and the operations are not interfered with each other. Correspondingly, the pot to be cooked placed above the panel 1 is usually a pot dedicated to the induction cooker, such as a cast iron pot, a stainless steel pot, etc.

Optionally, the central heating element 11 and the peripheral heating element 12 are both attached to the back of the panel 1, so that the installation and maintenance are simpler and more feasible, and the cost is low. The central heating element 11 and the peripheral heating element 12 may be adhered by one sheet of adhesive film or two separate sheets of adhesive films. Of course, it is also within the scope of the present application that one or both of the central heating element 11 and the peripheral heating element 12 are embedded in the panel 1, that is, when both are embedded in the panel 1, the central heating element 11 and the peripheral heating element 12 are integrally formed with the panel 1.

In the heat insulating device of the present invention, the shape of the heat insulating device is not limited, and the conventional panel 1 is generally circular, but is not limited thereto, and may be polygonal or the like. In addition, to further ensure the reliability and the service life of the product, in a specific embodiment, the central heating element 11 includes a central heating wire 111 spaced and wound and a plastic film 112 for attaching the central heating wire 111 to the panel 1, and the peripheral heating element 12 includes a peripheral heating wire 121 spaced and wound and a metal film 122 for attaching the peripheral heating wire 121 to the panel 1. The middle heating element 11 may not have the plastic film 112, but directly adopts a double-sided tape to stick the middle heating wire 111 to the back of the panel 1, which is also a protection scope of the present scheme.

Compared with the metal film 122, the plastic film 112 has the advantage that when the electromagnetic coil panel works, the magnetic lines of force generate eddy currents on the metal film 122, so that the metal film 122 generates heat to generate high temperature, and the service life of the heating wire is affected. Specifically, in order to prevent the magnetic force lines from penetrating through the middle heating component 11 and protect the middle heating component 11, the plastic film 112 is used initiatively, so that the magnetic force lines cannot generate eddy current heating on the plastic film 112, and the service life of the middle heating component 11 can be ensured and prolonged; in the peripheral heating element 12, the metal film 122 conducts heat generated by the peripheral heating element 12, so that heat heated by the heating wires of the peripheral heating element 12 is uniformly conducted to the panel 1 through the metal film 122, thereby improving the heating efficiency and making the heat generation more uniform. In addition, the plastic film 112 is usually a PET heat-resistant film, the metal film 122 is usually an aluminum film with very low magnetic permeability, and the heating wire (including the middle heating wire 111 and the peripheral heating wire 121) is made of a material with low magnetic permeability, such as carbon fiber and nickel alloy, so that when the electromagnetic coil panel works, the heat value caused by the eddy current formed by the generated magnetic lines of force on the metal film 122 and the heating wire is reduced to be within the safety value.

Further, to ensure the uniformity of dish warming over the entire panel 1, the spacing density of the central heating wires 111 is higher than that of the peripheral heating wires 121. This is because, the plastic film 112 used by the middle heating wire 111 has a lower heat transfer efficiency than the metal film 122, and accordingly, the arrangement density thereof is increased, so that the heating temperature of the whole panel 1 is more uniform, the dish warming effect of the whole table of dishes is more uniform, and the dining experience of the user is better.

Referring to fig. 5 and 6, an installation gap D is provided between the panel 1 and the chassis 2, and the value range of the installation gap D is 5-20 mm, for example, the installation gap D is 9 mm. This installation clearance D is not only favorable to providing fastening screw's installation space etc. sets up panel 1 and chassis 2 at an interval moreover, is favorable to preventing on panel 1's heat passes chassis 2, leads to influencing the life-span scheduling problem of the component of chassis 2 and top, and simultaneously, installation clearance D is favorable to whole heat preservation device's heat dissipation, and the effect is better.

As shown in fig. 3, the chassis 2 includes a circular and plate-shaped chassis body 21 and an annular outer ring portion 22 provided protruding above the chassis body 21, and an upper surface of the annular outer ring portion 22 is provided with a panel receiving portion 221 for receiving the panel 1. Further, the chassis body 21 is detachably connected to the annular outer ring portion 22. Thus, the chassis body 21 and the annular outer ring portion 22 can be made of different materials according to the actual production requirements, and the chassis body 21 is fixed to the annular outer ring portion 22 by screwing from the bottom thereof. Of course, the chassis body 21 and the annular outer ring portion 22 may be integrally formed.

Wherein, as shown in fig. 3 and 4, the middle part of the chassis 2 is usually provided with a middle furnace body mounting hole, the furnace body 3 is mounted in the middle furnace body mounting hole and protrudes downwards from the chassis 2, and the heat dissipation holes 32 are arranged on the outer circumference of the furnace body 3, so that the heat preservation device can dissipate heat in time in the working process, and the stability of the product performance is ensured.

Specifically, as shown in fig. 3 to 6, the heating assembly 31 is disposed in the middle of the furnace body 3, the furnace body 3 further includes at least two heat dissipation fans 33 disposed on the sides of the heating assembly 31, and the heat dissipation fans 33 are disposed side by side with the heating assembly 31 through the flow guiding member 34. The heat dissipation fan 33 is disposed through the bottom of the furnace body 3, and when the heat dissipation fan 33 works, the air flow can be sucked from the bottom of the through hole, and the heat is finally discharged from the heat dissipation holes 32 under the guiding action of the guiding member 34. The arrangement of the plurality of heat dissipation fans 33 makes the heat dissipation effect better.
