Induction cooker overflow protection device based on thermal expansion and cold contraction of gas

Abstract

An induction cooker overflow protection device based on thermal expansion and cold contraction of gas relates to the technical field of household appliances. The device comprises a cooker body, wherein a heating device is fixedly connected to the middle of the cooker body, electric heating blocks are fixedly connected to the inner bottom walls of two sides of the cooker body, resistors electrically connected with the electric heating blocks are fixedly connected to the inner walls of two sides of the cooker body, and the inner wall of the cooker body is fixedly connected with negative plates electrically connected with the resistors. According to the induction cooker overflow protection device based on thermal expansion and cold contraction of gas, through cooperative use of the electric heating blocks and electric contacts, when water exists on the upper surface of the induction cooker, the water flows into a water collecting tank, the two electric contacts are electrically connectedat the moment, a circuit of the electric heating blocks is connected, and the electric heating blocks heat compressed gas, so that the compressed gas expands and moves piston blocks upwards, and the electric heating blocks stop heating until conductive blocks are not electrically connected with conductive plates, so that the effect of thermal expansion of gas is achieved, the induction cooker is more sensitive to water, and meanwhile, excessive expansion of compressed gas is prevented.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a water overflow protection device for an induction cooker based on thermal expansion and contraction of gas. Background technique [0002] Household appliances mainly refer to the power equipment that is often used in daily life to facilitate life. The equipment of household appliances can effectively improve and improve the quality of life, and can also increase choices under limited resource conditions, thereby making life more convenient. Among them, induction cooker is One of such household appliances. [0003] The induction cooker converts electric energy into heat energy and heats the pot to realize the function of cooking. It is safe and secure without the use of an open flame. However, the current induction cooker often encounters some problems during use. For example, when using an induction cooker, You must pay attention to the safety of water, because on...

[0003] The induction cooker converts electric energy into heat energy and heats the pot to realize the function of cooking. It is safe and secure without the use of an open flame. However, the current induction cooker often encounters some problems during use. For example, when using an induction cooker, You must pay attention to the safety of water, because once water enters the induction cooker, it will cause a short circuit of the induction cooker, cause the circuit to burn, and may cause the circuit to catch fire, causing a fire, and there are potential safety hazards
