The invention discloses a water shortage detection circuit and household appliances. The water shortage detection circuit comprises a heating module and a temperature control module, wherein the heating module is used for heating liquid in a container to evaporate the liquid; and the temperature control module is arranged on the outer wall of the container and is connected in series with the heating module to form a series circuit for disconnection when the surface temperature of the container exceeds a first preset temperature due to the liquid in the container being lower than the preset value. The water shortage detection circuit can realize water shortage detection by using the heating module and the temperature control module arranged on the outer wall of the container, when the temperature control module is turned on, the container is indicated of no water shortage, and when the temperature control module is disconnected, the container is indicated of water shortage, so that water shortage detection is realized through the state of the temperature control module. The water shortage detection circuit has simple structure, convenient routing and production and mounting, and solves the defects of complicated routing and production and assembly of the water shortage detection device formed by a liquid level switch, a reed switch and the like in the prior art.
Description
technical field [0001] The invention relates to the technical field of household appliances, in particular to a water shortage detection circuit and household appliances. Background technique [0002] As a common household appliance, electric heater has been widely used in people's daily life. With the use of electric heaters, the humidity of the environment will gradually decrease. In order to better meet the needs of users and improve the quality of life, electric heaters with humidification functions have gradually become mainstream products. [0003] The electric heater with humidification function needs to be equipped with a water shortage detection device. The water shortage detection device will stop the humidification function when it detects water shortage, so as to prevent the electric heater from being damaged or exploded when the water shortage is still in the humidification state. Waiting for danger. At present, water shortage detection is basically realized b...
