Elastic heating body mounting structure for miniature electric rice cooker

Abstract

The invention relates to an elastic heating body mounting structure for a miniature electric rice cooker. The elastic heating body mounting structure comprises an outer pot, an inner container and an electric heating device. The elastic heating body mounting structure is characterized in that a middle layer is arranged inside the outer pot, an inner cavity is formed in the middle layer, the electric heating device is arranged on the lower portion of the inner cavity of the middle layer and comprises a heat conducting tray and an electric heating body, the electric heating body is connected at the bottom of the heat conducting tray, a gap is reserved between the electric heating device and the bottom wall of the inner cavity of the middle layer, an elastic part is arranged between the electric heating device and the bottom wall of the inner cavity of the middle layer, the electric heating device is seated on the elastic part, and the inner container is arranged in the inner cavity of the middle layer and elastically contacts with the heat conducting tray of the electric heating device. The elastic heating body mounting structure for the miniature electric rice cooker has the advantages that the structure is simple and reasonable, the inner container is separated from the heating device, can be independently taken out and used and is uniformly heated, heat is not easily lost, heat efficiency is obviously improved and the like.

Description

technical field [0001] The invention relates to a miniature electric cooker, in particular to an elastic heating body installation structure of the miniature electric cooker. Background technique [0002] Existing miniature rice cooker comprises outer pot, inner container and electric heating device, and electric heating device is PTC heating element, and PTC heating element is fixed on the bottom wall of inner container, that is: inner container and PTC heating element are fixedly connected; During work, The PTC heating element energizes and generates heat, and transfers the heat to the bottom wall of the inner tank. [0003] However, the heating body installation structure of the miniature rice cooker with the above-mentioned traditional structure has the following disadvantages: (1) The PTC heating body is fixed on the bottom wall of the inner pot, and the inner pot cannot be taken out, and the inner pot is only heated by the bottom PTC heating body (heat transfer) There...

Problems solved by technology

[0003] However, the heating body installation structure of the miniature rice cooker with the above-mentioned traditional structure has the following disadvantages: (1) The PTC heating body is fixed on the bottom wall of the inner pot, and the inner pot cannot be taken out, and the inner pot is only heated by the bottom PTC heating body (heat transfer) Therefore, the traditional PTC heating rice cooker is unevenly heated and the thermal efficiency is low; (2) In view of the fact that the heat around the inner pot is easy to lose, and the heating is concentrated at the bottom of the inner pot, this heating is not uniform. Seriously affect the taste of the cooked food; even because the bottom wall of the inner tank is connected with a jump-type thermostat, and the bottom wall of the inner tank is too high, the temperature controller is cut off too early for protection, resulting in a distance from the bottom wall of the inner tank The food on the upper part of the inner tank is not cooked, which makes the food wasteful; (3) The fixed connection between the inner tank and the PTC heating element not only causes installation troubles, but also causes certain inconvenience to daily use because the inner tank cannot be taken out separately
