Temperature-sensing element mounting structure for miniature electric rice cooker

Abstract

The invention relates to a temperature-sensing element mounting structure for a miniature electric rice cooker. The temperature-sensing element mounting structure comprises an outer pot, an inner container and an electric heating device, 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, and the electric heating body is connected at the bottom of the heat conducting tray. The temperature-sensing element mounting structure is characterized by further comprising a temperature-sensing element and an elastic part thereof, and the temperature-sensing element is arranged below the bottom wall of the inner container through the elastic part and elastically contacts with the bottom wall of the inner container. The temperature-sensing element mounting structure for the miniature electric rice cooker has the advantages that the structure is simple and reasonable, the temperature-sensing element is easily mounted and replaced, temperature data of the inner container can be transmitted in real time, multifunctional and intelligent control is realized, the inner container 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 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
