Heating body elastic supporting structure of mini electric cooker

Abstract

The invention relates to a heating body elastic supporting structure of a mini electric cooker. The heating body elastic supporting structure comprises an outer pot, an inner pot and an electric heating device. A middle layer is arranged in the outer pot and provided with an inner cavity. The electric heating device comprises a heat conducting tray and an electric heating body. The electric heating body is connected to the bottom of the heat conducting tray. The heating body elastic supporting structure is characterized in that the electric heating device is arranged at the lower portion of the inner cavity of the middle layer through a sheet elastic body, gaps are reserved between the electric heating device and the bottom wall of the inner cavity of the middle layer and between the electric heating device and the side wall of the inner cavity of the middle layer, the sheet elastic body is integrally formed by a bearing face, a supporting face and an elastic face, the bearing face and the supporting face are vertically staggered, the bearing face is connected with the electric heating body, the supporting face is connected with the middle layer, the elastic face is connected between the bearing face and the supporting face, and an inner container is arranged in the inner cavity of the middle layer and makes elastic contact with the heat conducting tray. The electric heating device of the mini electric cooker of the structure is supported by the sheet elastic body stably and reliably, so that it is guaranteed that the electric heating body makes contact with the inner container well, and the heat transfer effect is good.

Description

technical field [0001] The invention relates to a miniature rice cooker, in particular to an elastic support structure of a heating body of the miniature rice 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) Therefore, th...

[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

However, this structure has the following disadvantages: (1) The spring shakes from side to side, so that the electric heating device supported by it is easy to shake from side to side. There is a large degree of wear at all positions, so that the thermal conductivity is reduced; (2) The installation of the spring requires a vertical guide structure, which increases the difficulty and cost of its installation
