The installation structure of the temperature sensing element of the miniature rice cooker

Abstract

The invention relates to a temperature-sensing element installation structure of a miniature electric rice cooker, which comprises an outer pot, an inner tank and an electric heating device. A middle layer is arranged inside the outer pot, an inner cavity is arranged on the middle layer, and an electric heating device is arranged at the lower part of the inner cavity of the middle layer. The heating device includes a heat conduction tray and an electric heating element, and the electric heating element is connected to the bottom of the heat conduction tray. It is characterized in that it also includes a temperature sensing element and its elastic member. The temperature sensing element is in elastic contact with the bottom wall of the inner pot; the installation structure of the temperature sensing element of this miniature rice cooker has a simple and reasonable structure, and the temperature sensing element is easy to install and replace. It can transmit the temperature data of the inner pot in real time, realizing multi-function and Intelligent control, and the inner tank is heated evenly, the heat is not easy to lose, and the thermal efficiency is obviously improved.

Description

technical field [0001] The invention relates to a miniature electric cooker, in particular to a mounting structure of a temperature sensing element 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 is fixedly connected with PTC heating element, and the bottom of inner container The wall is also connected with a jump-type thermostat; when working, the thermostat directly senses the temperature of the bottom wall of the inner tank, and the power is cut off for protection when overheating; the connection structure of the miniature rice cooker thermostat with the above-mentioned traditional structure has the following deficiencies: (1) The jump-type thermostat is directly connected to the bottom wall of the inner tank, and ...

Problems solved by technology

[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 is fixedly connected with PTC heating element, and the bottom of inner container The wall is also connected with a jump-type thermostat; when working, the thermostat directly senses the temperature of the bottom wall of the inner tank, and the power is cut off for protection when overheating; the connection structure of the miniature rice cooker thermostat with the above-mentioned traditional structure has the following deficiencies: (1) The jump-type thermostat is directly connected to the bottom wall of the inner tank, and is in fixed contact with the inner tank, which not only makes the installation of the thermostat cumbersome, but also makes it inconvenient to replace the thermostat; (2) The controller generally only has the function of overheating power-off protection, or reset and power-on, which is equivalent to a "temperature control switch". The user cannot adjust the set temperature control value. The data is transmitted to the control device to realize the multi-functional and intelligent control of the rice cooker; (3) The PTC heating element is fixed on the bottom wall of the inner pot, and the inner pot cannot be taken out, which causes some inconvenience to use; moreover, the inner pot is only controlled by the bottom PTC The heating element heats up (heat transfer), and the heat is easily lost to the surroundings. Therefore, the traditional PTC-heated rice cooker is unevenly heated, and the thermal efficiency is low. What's more, since the heat around the inner pot is easy to lose, the heating is concentrated at the bottom of the inner pot. , the temperature of the bottom wall of the inner tank is too high, and the thermostat will immediately cut off the power for protection, which may easily cause the food to be undercooked, and the rice cooker will be powered off and will not work
