Abstract

The utility model discloses an energy economizer, which can increase the heat efficiency of the induction cooker, and reduce the electric power consumption of the induction cooker. An insulating device made of heat insulating material is used between the table top of the induction cooker and the side surface of the heating container, which can reduce the heat dissipating capacity of the heating container, shorten the heating time of the food in the heating container, and the goal of electric energy saving is achieved. With the insulating device, the position of the heating container can be fixed, and the heating container can not be moved under the action of the external force.

Description

Energy economizer

A kind of energy saver that the utility model belongs to can be improved the electromagnetic stove heat efficiency, reduce the electromagnetic stove power consumption.

The electromagnetic stove heat efficiency of Chu Shouing is introduced up to more than 80% in specification usually in the market.In fact, this is the heat efficiency that 25 degree just can reach when above in ambient temperature just; When ambient temperature is lower than 25 degree or when lower, the heat efficiency of electromagnetic stove just is difficult to or can not reaches 80%.The heating principle of electromagnetic stove is to form a closed-loop path by the metallic object that is wound with coil in heating container on the electromagnetic stove table top and the electromagnetic stove, the pan head that heating container is normally made with permeability magnetic material, when coil is connected with alternating current, in the closed-loop path, promptly can produce very big vortex flow.To emit a large amount of joules like this in the bottom of heating container---Lenz's heat is come, and makes the food in the heating container begin progressively up to heat from the bottom.At this moment the side surface at heating container will will distribute certain heat by air, and particularly when boiling the food of soup and so on, heat distributes bigger.In fact, distributing of heat is relevant with ambient temperature, and ambient temperature is low more, and distributing of heat is just big more, and the power consumption of electromagnetic stove is also just big more.On the other hand, the table top of electromagnetic stove adopts devitrified glass to make, and the surface is very smooth, and when contact and being used in the cooking such as stir-frys, burning with pan head bottom surface, the pot head is easy to be shifted, and uses very inconvenient.

The objective of the invention is to disclose a kind of heat dissipation capacity that can reduce heating container on the electromagnetic stove table top, reach and improve the electromagnetic stove heat efficiency and can guarantee the device that heating container is not easy to be shifted.

The utility model is achieved in that with a kind of insulation material as asbestos, wood ash and so on makes the annular attemperator that a upper and lower surface is a through hole, and attemperator is placed on the electromagnetic stove table top.A heating container can be seated in the through hole of attemperator, and guarantees that the bottom surface of heating container and the table top of electromagnetic stove reach excellent contact.

Advantage of the present utility model is: utilized an attemperator between the side surface of electromagnetic stove table top and heating container, reduced the heat dissipation capacity of heating container like this, shortened the heating time of food, reached the purpose of saves energy.And by attemperator, fixed heating container, and can be owing under the effect of external force, making the heating container displacement.

In conjunction with the accompanying drawings the present invention is further described:

Fig. 1 is a schematic diagram of the present invention.

Fig. 2 is the longitudinal profile schematic diagram of Fig. 1.

With reference to Fig. 2, the built-in insulation material (4) that is placed with of the container of an annular outer cover (3), shell (3) are to make with metal such as aluminium, copper or nonmetal temperature-resistant material as asbestos and so on.Shell and insulation material constitute attemperator.Attemperator is placed on the table top (2) of electromagnetic stove (1), and a heating container (5) can be placed in the interior annular distance of attemperator.The interior ring upper limb of attemperator is spill, and an annular ring (6) is seated in the interior ring spill of attemperator.Annular ring (6) adopts the hard temperature-resistant material to make, and its effect is to make the heating container that can cooperate all size.

Claims

1, a kind of energy saver that is used to be seated on the electromagnetic stove table top is characterized in that it is to be made of an annular thermal insulator and the annular ring that is seated on the thermal insulator.
