Abstract

An insulation disc for an electric pan belongs to the field of the components for kitchen heating devices. The insulation disc comprises a disc body and is characterized in that the disc body is a concave disc with a sunken middle part. The insulation disc has the advantages that the insulation disc is arranged between a heating disc and a pedestal of the electric pan, so that the electric elements in the pedestal can be separated from the heating disc to irradiate part of the heat energy transferred and irradiated by the heating disc to the pedestal. Therefore, the insulation disc prevents the electric elements in the pedestal not to working in a high-temperature environment for a long time so as to extend the service life of the electric elements, thus prolonging the service life of the electric pan.

Description

A kind of electric food warmer thermal insulating disc

Technical field

The utility model belongs to the field of components of kitchen heating apparatus, is specifically related to a kind of thermal insulating disc.

Background technology

At present, electric food warmer has become family's indispensable kitchen utensils such as cook, cook.Existing electric food warmer generally all directly is placed on electric food warmer pot body on the base.In electric food warmer pot body, cook, when cooking, when heat-generating disc sends heat energy heating electric food warmer pot body, have partial heat energy and give electric_pan pedestal, cause the electrical equipment in the base can be in a hot environment, the service life of having reduced electrical equipment for a long time by heat conduction and radiation.

The utility model content

In order to overcome the drawback of prior art, the utility model provides a kind of electric food warmer thermal insulating disc, and it has heat-blocking action, prevents that the cavity temperature of placement electrical equipment in the base is too high, prevents that effectively electrical equipment is damaged in the base.

The technical scheme that its technical problem that solves the utility model adopts is: design a kind of electric food warmer thermal insulating disc, comprise disk body, it is characterized in that disk body is middle recessed recessed dish.

The inside and outside surface of disk body of the present utility model is a cambered surface, and the cambered surface quantity on the inside and outside surface of disk body is greater than one, and the curvature difference of each cambered surface.The inside and outside surface of disk body is upper and lower cambered surface, and the curvature of last cambered surface is less than the curvature of lower camber side.Louvre is offered in the bottom of disk body.

The beneficial effect that the utility model had is: the utility model is placed between the heat-generating disc and base of electric food warmer, make between interior electrical equipment of base and the heat-generating disc isolated, heat-generating disc is conducted in base and the partial heat energy of radiation dissipates, prevent that electrical equipment continues to work in the base under a hot environment, improved the service life of electrical equipment.Thereby improved the service life of electric food warmer.

Description of drawings

Fig. 1 is the structural representation of embodiment of the present utility model;

Fig. 2 is that the A of Fig. 1 is to view;

Fig. 3 is the utility model user mode structural representation;

The 1. outer cambered surfaces that go up among the figure go up cambered surface in 2., 3. outer lower camber side, 4. interior lower camber side, 5. louvre, 6. thermal insulating disc, 7. louvre, 8. louvre, 9. heat dissipation plate, 10. base, 11. pots of bodies.

The specific embodiment

As shown in Figure 1, the outer surface of thermal insulating disc 6 is divided into outer cambered surface 1 and the outer lower camber side 3 of going up, and goes up cambered surface 2 and interior lower camber side 4 in inner surface is divided into.The outer curvature that goes up the curvature of cambered surface 1 less than outer lower camber side 3, the interior curvature that goes up the curvature of cambered surface 2 less than interior lower camber side 4.Offer louvre 5 in the bottom of thermal insulating disc 6.

As shown in Figure 3, pot body 11 is placed on the thermal insulating disc 6, the thermal insulating disc 6 following heat dissipation plates 9 of placing, and heat dissipation plate 9 is placed on the base 10.There is cavity between thermal insulating disc 6 and the pot body 11, its contact-making surface is little, thereby only has few partial heat energy conduction and radiation to give thermal insulating disc 6, because thermal insulating disc 6 and heat dissipation plate 9 have cavity, its contact-making surface is little, thereby only has few partial heat energy conduction and radiation to give heat dissipation plate 9.Thereby the partial heat energy that heat-generating disc distributed of pot body 11 only has only a few to conduct to heat dissipation plate 9.Conduction discharges for the heat energy of heat dissipation plate 9 by the venting cavity between heat dissipation plate 9 and the base 10.By above-mentioned design, the heat energy on the pot body 11 almost can't conduct with radiation gives base 10, has played effect of heat insulation preferably.Even there is the portion of hot air-flow in the base 10, also can discharge by the cavity of heat dissipation plate 9 belows.Environment temperature in the base 10 is lower, the electrical equipment long service life in it.
