Temperature sensor for electric cooker

Abstract

The invention aims to provide a temperature sensor for an electric cooker. In the temperature sensor for the electric cooker, an insulating bush and an electric wire can be gathered and bound reliably. Moreover, the temperature sensor is simple in structure and convenient to install, and the safety of the electric cooker can be enhanced greatly. The temperature sensor for the electric cooker comprises a binding wire and an aluminum cover, wherein a thermistor and a thermofuse are arranged in the aluminum cover through a bracket, are sleeved in the insulating bush respectively, and are connected with a lead which is led out of the aluminum cover respectively. Key points are that the bracket is provided with a support claw; the support claw is provided with a U-shaped clamping portion; the U-shaped clamping portion is used for clamping and fixing the insulating bush on which the thermistor and / or thermofuse is positioned; the binding wire passes through a gap between the support claw and the insulating bush, and is meshed crossly after being wrapped around the insulating bush; the two ends of the binding wire are tied together or wound firmly after being wound around the lead by at least one circle.

Description

technical field [0001] The invention relates to a temperature sensor for an electric rice cooker, in particular to a temperature sensor for an electric rice cooker which can reliably bundle and bundle insulating sleeves and electric wires. Background technique [0002] At present, the temperature sensor of an electric cooker is generally composed of an aluminum cover, a thermistor, a thermal fuse, an electric wire, an insulating sleeve, and a binding wire. The bundled wire bundles the wires so that they are in the center. However, this method of bundling is only to tighten the bundles of the wires. Because the diameter of the sleeve is much larger than that of the wires, the sleeve is not well gathered in the center, and because the surface of the silicone wire It is relatively slippery, and the binding position is easy to slip away from the casing end during assembly and use. For example, a temperature sensor with double insurance is disclosed in "A New Type of Rice Cooker...

Problems solved by technology

The bundled wire bundles the wires so that they are in the center. However, this method of bundling is only to tighten the bundles of the wires. Because the diameter of the sleeve is much larger than that of the wires, the sleeve is not well gathered in the center, and because the surface of the silicone wire It is relatively slippery, and the binding position is easy to slip away from the casing end during assembly and use. For example, a temperature sensor with double insurance is disclosed in "A New Type of Rice Cooker Temperature Sensor" (Patent No. ZL2012 2 0187962.9). There are many tubes, it is difficult to bundle the sleeves well, and if the sleeves are bundled, it cannot be tied tightly because the sleeves are tapered after being bundled.

As a result, the insulating sleeve is easy to scratch with the fixed plate, which will easily cause the temperature sensor of the rice cooker to move up and down flexibly and reduce the insulation performance
