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

Example Embodiment

[0028] Embodiment one: if Figure 1 to Figure 3 As shown, the installation structure of the elastic heating body of the miniature electric cooker includes an outer pot 1, an inner tank 2 and an electric heating device 3, and is characterized in that, the outer pot 1 is provided with a middle layer 4, and the middle layer 4 is provided with an inner cavity 41, and the electric heating device The heating device 3 is arranged at the bottom of the inner cavity 41 of the middle layer 4. The electric heating device 3 includes a heat conducting tray 5 and an electric heating element 6. The electric heating element 6 is connected to the bottom of the heat conducting tray 5. There is a gap 7 between them, an elastic member 8 is arranged between the electric heating device 3 and the bottom wall 42 of the middle inner cavity, the electric heating device 3 sits on the elastic member 8, and the liner 2 is arranged in the inner cavity 41, And elastically contact with the heat conduction tra...

Example Embodiment

[0036] Embodiment two: if Figure 5 to Figure 7 As shown, it is a schematic diagram lacking an inner container. This embodiment is similar to the first embodiment above, the difference is only: the elastic member 8 includes a spring 81, a bolt 82, an upper nut 841 and a lower nut 831, and the lower end of the bolt 82 Extending out of the bottom of the electric heating device 3, it is first screwed with the upper nut 841, then passed through the through hole 422 of the middle bottom wall, and then screwed with the lower nut 831, the upper nut 841 is close to the bottom wall of the electric heating device 3, and the spring 81 The bolts 82 are sleeved between the upper nut 841 and the middle bottom wall 42 , and there is a gap between the bolts 82 and the through holes 422 of the middle bottom wall.

[0037] An upper washer 8411 and a lower washer 8311 are respectively arranged between the spring 81 and the upper nut 841 , and between the spring 81 and the lower nut 831 .

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...
