Abstract

The utility model discloses an electric cooker with purple granulated internal bladder and high heating efficiency and low heat waste, which comprises a body and a cover. The body mainly comprises a case, a heat-insulated bladder inside the case, a heat conducting bladder, a purple granulated internal bladder, a heating plate, a heating tape and a temperature limiter under the center of the internal bladder. The heating plate, convex table at the bottom of the heat conducting bladder and upper surface of the heating plate are all plane. The upper surface and the convex table are of full surface-on-surface touch, so are the convex table and outer surface of the internal bladder, so most of heat from the heating plate is transmitted to the bottom of the internal bladder. Compared with a traditional electric cooker. The utility model has the advantages of high heat utilization, even heat exposure, quick heating, easy production and lower cost.

Description

Cooker with purple granulated liner

Technical field

The utility model relates to a kind of electric cooker, relates in particular to a kind of electrically heated cooker with purple granulated liner, belongs to the household kitchen electric appliance production field.

Background technology

The traditional electrical pot for cooking rice is made up of pot body and pot cover, wherein the pot body is made up of pot body and pot cover, wherein the pot body mainly comprises heat insulation courage, heat conduction courage, red-clay inner, heating board, heating tape in shell, the shell and the temperature limiter that is positioned at the red-clay inner central lower, heating board and heating tape are close to outer bottom and the outer circumferential walls that is installed on the heat conduction courage respectively, and temperature limiter directly contacts with the bottom of red-clay inner after passing the centre bore of heating board and heat conduction courage.In the above structure, the outer bottom of red-clay inner is provided with bulge loop, in order steadily to place red-clay inner and to conduct heat better, correspondingly on heat conduction courage and heating board, also be provided with corresponding bulge loop or groove, the weak point of this structure is: owing to produced the gap between red-clay inner and heat conduction courage and the heating board, so will inevitably cause heat that heating board produces not arrive red-clay inner (because the heat transmission of gap is that convection current is with radiation rather than contact transmission with the fastest speed, speed is slower), can in transmittance process, be depleted but also have the part heat, thereby cause the reduction of heat utilization ratio, Fu Za structure can give to produce in addition increases difficulty and increases cost.

Summary of the invention

The purpose of this utility model be exactly a kind of efficiency of heating surface height to be provided in order addressing the above problem, to be heated evenly, cooker with purple granulated liner that thermal losses is little.

The utility model achieves the above object in the following manner:

The utility model also is made up of pot body and pot cover, wherein the pot body mainly comprises shell, heat insulation courage in the shell, the heat conduction courage, red-clay inner, heating board, heating tape and the temperature limiter that is positioned at the red-clay inner central lower, heating board and heating tape are close to outer bottom and the outer circumferential walls that is installed on the heat conduction courage respectively, temperature limiter directly contacts with the bottom of red-clay inner after passing the centre bore of heating board and heat conduction courage, wherein, the outer bottom of described red-clay inner, be the plane above the round boss of described heat conduction courage bottom and the described heating board, the outer bottom complete face face of the round boss of the top and heat conduction courage of heating board contacts, and the inner bottom surface of the round boss of heat conduction courage contacts with the outer bottom complete face face of red-clay inner.

We know that the transmission of heat has three kinds of modes: convection current, radiation and directly contact, in these three kinds of modes, direct contact heat transfer is the fastest, and its loss also is minimum.Owing to be complete face face contact very close to each other between red-clay inner, heat conduction courage and the heating board in the utility model, so the heat that heating board produces almost completely is the outer bottom that is delivered to red-clay inner by the mode of direct contact, not only speed is fast, even, and thermal losses is minimum; In addition since the round boss of the outer bottom of red-clay inner, heat conduction courage bottom and heating board above be the plane, can effectively reduce raw material and be convenient to processing.

The beneficial effects of the utility model are:

As from the foregoing, compare with the traditional electrical pot for cooking rice, the utility model heat utilization ratio height, be heated evenly, heat fast, produce easily and cost lower.

Description of drawings

Accompanying drawing is a cutaway view of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described in detail:

As shown in drawings, the utility model is made up of pot body and pot cover 1, wherein the pot body mainly comprises shell 2, heat insulation courage 3 in the shell, heat conduction courage 4, red-clay inner 5, heating board 6, heating tape 7 and the temperature limiter 8 that is positioned at red-clay inner 5 central lower, heating board 6 and heating tape 7 are close to outer bottom and the outer circumferential walls that is installed on heat conduction courage 4 respectively, temperature limiter 8 directly contacts with the bottom of red-clay inner 5 after passing the centre bore of heating board 6 and heat conduction courage 4, wherein, the outer bottom of red-clay inner 5, be the plane above the round boss of heat conduction courage 4 bottoms and the heating board 6, the outer bottom complete face face of the round boss of the top and heat conduction courage 4 of heating board 6 contacts, and the inner bottom surface of the round boss of heat conduction courage 4 contacts with the outer bottom complete face face of red-clay inner 5.

We know that the transmission of heat has three kinds of modes: convection current, radiation and directly contact, in these three kinds of modes, direct contact heat transfer is the fastest, and its loss also is minimum.Owing to be complete face face contact very close to each other between red-clay inner 5, heat conduction courage 4 and the heating board 6 in the utility model, so the heat that heating board 6 produces almost completely is the outer bottom that is delivered to red-clay inner 5 by the mode of direct contact, not only speed is fast, even, and thermal losses is minimum; In addition since the round boss of the outer bottom of red-clay inner 5, heat conduction courage 4 bottoms and heating board 6 above be the plane, can effectively reduce raw material and be convenient to processing.

Claims

1, a kind of cooker with purple granulated liner, form by pot body and pot cover, wherein the pot body mainly comprises shell, heat insulation courage in the shell, the heat conduction courage, red-clay inner, heating board, heating tape and the temperature limiter that is positioned at the red-clay inner central lower, heating board and heating tape are close to outer bottom and the outer circumferential walls that is installed on the heat conduction courage respectively, temperature limiter directly contacts with the bottom of red-clay inner after passing the centre bore of heating board and heat conduction courage, it is characterized in that: the outer bottom of described red-clay inner, be the plane above the round boss of described heat conduction courage bottom and the described heating board, the outer bottom complete face face of the round boss of the top and heat conduction courage of heating board contacts, and the inner bottom surface of the round boss of heat conduction courage contacts with the outer bottom complete face face of red-clay inner.
