Micro rice cooker with improved structure

Abstract

The invention relates to a miniature rice cooker with an improved structure, which comprises an outer pot, an inner pot and an electric heating device, the outer pot is provided with a middle layer, the middle layer is provided with an inner cavity, and the electric heating device is arranged in the inner cavity of the middle layer, and the feature is that the The electric heating device includes a heat conduction tray and an electric heating body, the heat conduction tray is on the top, and the electric heating element is on the bottom, and the two are in close contact with each other. A support body is arranged below the middle bottom wall inside the outer pot. There is a connecting component between the body and the support body to connect and fix them together; this improved structure of the miniature rice cooker has a simple and reasonable structure, the inner pot and the heating device are separated, the inner pot can be taken out and used separately, and the heating is uniform, the heat It is not easy to be lost, and the thermal efficiency is obviously improved, and the supporting structure of the heating device is simple and reasonable.

Description

technical field [0001] The invention relates to a miniature electric cooker, in particular to a miniature electric cooker with an improved structure. Background technique [0002] The existing miniature rice cooker includes an outer pot, an inner container and an electric heating device. The electric heating device is a PTC heating element, and the PTC heating element is installed on the bottom wall of the inner container through a fixed assembly, that is, the inner container and the PTC heating element are fixedly connected. ; When working, 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 PT...

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) Since the heat is easily lost around the inner pot, and the heating is concentrated at the bottom of the inner pot, this heating is uneven and serious. 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 the inner tank far away from the bottom wall of the inner tank. The food on the upper part of the 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 some inconvenience to daily use because the inner tank cannot be taken out separately; (4) The inner tank and the PTC heating element are connected by a fixing component, which includes bolts welded to the bottom of the inner tank and fixing nuts used to cooperate with the bolts. Since the bottom wall of the inner tank needs to be welded with bolts, The process is complex and difficult, and the bolts are often loosened due to weak welding
