Abstract

The utility model discloses a recessed formula induction cooker panel, it includes panel main part (1), the position department that corresponds the pan on panel main part (1) upper surface is equipped with recess (2), recess (2) are circular recess, and the radius of recess (2) is less than the radius of pan bottom surface. The utility model discloses a recess that the setting is located panel main part upper surface to correspond the position of pan, and the radius of recess is less than the radius of pan bottom surface, and the edge and the contact of panel main part that can make the pan pass through its bottom surface have reduced the area of contact of panel main part with the pan bottom surface greatly to reduced and conducted heat and heat radiating area, reduced the heat and run off and improved the thermal efficiency, simultaneously, can also support the pan through the panel main part in the recess outside, avoid the setting of recess and influence the support atress of pan, improved the stability that the pan supported the atress. The utility model discloses not only can reduce the heat and run off, still have the advantage that the thermal efficiency is high.

Description

A kind of up concave type electromagnetic oven panel

Technical field

This utility model is related to a kind of up concave type electromagnetic oven panel.

Background technology

Electromagnetic oven typically using the principle of heating of magnetic field induction electric current (being also called vortex), by electronic circuit board portion is constituted Point produce alternating magnetic field, when being placed on panel with the bottom of pan containing irony, pan cut alternate magnetic force line and in pan Bottom metal portion produces the electric current (being vortexed) of alternation, and it is in swirling that vortex makes the free electron in the ferrous material of pan bottom Alternate motion, makes the bottom of a pan generate heat by the Joule heat of electric current.Therefore the thermal source that electromagnetic oven is cooked come from pan bottom rather than Electromagnetic oven heating itself is conducted to pan, so the thermal efficiency is higher by much than the efficiency of all cookers, makes utensil itself certainly Row generates heat at a high speed, for heating and cooking food, so as to reach the purpose cooked.

But, existing electromagnetic oven panel and pan bottom plane contact, the area of contact surface is larger, panel pair during heating Heat on pan carries out large-area heat transfer and radiating, causes heat losses larger and the relatively low problem of the thermal efficiency.

Utility model content

The purpose of this utility model is, there is provided a kind of up concave type electromagnetic oven panel.This utility model can not only be reduced Heat losses, also have the advantages that the thermal efficiency is high.

The technical solution of the utility model：A kind of up concave type electromagnetic oven panel, including panel body, panel body upper surface Groove is provided with the position of upper correspondence pan；Groove is circular groove, and the radius of groove is less than the radius of pan bottom.

In a kind of aforesaid up concave type electromagnetic oven panel, little more than the 3mm of radius of the radius ratio pan bottom of the groove.

In a kind of aforesaid up concave type electromagnetic oven panel, in the groove heat-preservation cotton is provided with.

Compared with prior art, this utility model improves existing faceplate structure of electromagnetic oven, and by arranging panel is located at The groove of body upper surface leads to can pan corresponding to the position of pan, and the radius of groove less than the radius of pan bottom The edge for crossing its bottom surface contacts with panel body, substantially reduces the contact area of panel body and pan bottom, so as to subtract Heat transfer and area of dissipation are lacked, have reduced heat losses and improve the thermal efficiency；Simultaneously, additionally it is possible to by the panel on the outside of groove Main body is supported to pan, it is to avoid the setting of groove and affect the support stress of pan, improve pan support stress it is steady It is qualitative.Additionally, little more than the 3mm of radius of the radius ratio pan bottom of groove of the present utility model, it is ensured that pan and panel it Between monolateral stress surface, further increase support stress stability；By in groove arrange heat-preservation cotton formed pan with Heat insulating effect between panel, has prevented heat transfer and the loss of pan bottom, realizes the heat zero of pan bottom It is lost in, and then improves the thermal efficiency.Therefore, this utility model can not only reduce heat losses, also with high excellent of the thermal efficiency Point.

Description of the drawings

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

Fig. 2 is structural representation when this utility model is used.

Labelling in accompanying drawing for：1- panel bodies, 2- grooves, 3- heat-preservation cottons, 4- pans.

Specific embodiment

This utility model is further described with reference to the accompanying drawings and examples, but is not intended as to this utility model The foundation of restriction.

Embodiment.A kind of up concave type electromagnetic oven panel, is constituted as shown in Figure 1, 2, including panel body 1, in panel body 1 Groove 2 is provided with surface at the position of correspondence pan 4；Groove 2 is circular groove, and the radius of groove 2 is less than the half of the bottom surface of pan 4 Footpath.

Little more than the 3mm of radius of the bottom surface of radius ratio pan 4 of the groove 2；Heat-preservation cotton 3 is provided with the groove 2.

Operation principle：Groove 2 is located on the laminating contact surface of panel 1 and pan 4, make the central area of pan 4 not with panel 1 Directly contact；Meanwhile, the radius of groove 2 makes the panel 1 in the outside of edge contact groove 2 of pan 4 less than the radius of pan 4 On, it is easy to panel 1 to support pan 4, it is ensured that pan 4 is stably placed.Heat-preservation cotton 3 in groove 2 can directly completely cut off the bottom surface of pan 4 Heat, reduce heat losses, improve the thermal efficiency.Heat-preservation cotton 3 can have high-temperature resistant for glass fibre, ceramic fibre etc. Property, the fiber-like film of high thermal insulation, high abrasion scratch-resistant, high acid and alkali-resistance.
