Abstract

The invention provides a water shortage detection method for a smart home appliance, a device and the smart home appliance. The method comprises the steps of obtaining a selection operation of a useron an operation interface of the smart home appliance, wherein the selection operation includes a steaming mode; when the steaming mode starts working and a heating pipe is in an on or off state, periodically detecting a first surface temperature and a second surface temperature of a steam generator within a preset time, and determining the water quantity state of the smart home appliance according to a rising rate, a falling rate or a temperature difference of the first surface temperature and / or the second surface temperature; the first surface temperature is the surface temperature of an inlet pipe side of the steam generator, the second surface temperature is the surface temperature of an outlet pipe side of the steam generator, the current smart home appliance is detected whether to be in a water shortage state by various judgment methods, the detection accuracy is high, the stability and reliability of a product are improved, the internal space of the smart home appliance is optimized, and the space utilization rate of the smart home appliance is improved.

Description

technical field [0001] The invention relates to the technical field of smart home appliances, in particular to a water shortage detection method and device for smart home appliances and the smart home appliances. Background technique [0002] At present, the integrated steaming and roasting machine is a smart home appliance with a steaming function. The water shortage detection of the steaming function in the integrated steaming and roasting machine is to judge whether water injection is currently required through a flow meter or a water level detection system. The flow meter or water level detection system only detects the water level, and the detection accuracy is low. [0003] In addition, it is often necessary to install a flow meter or a water level detection system in the smart home appliance, so that the internal space of the smart home appliance is narrow and the space utilization rate is low. Contents of the invention [0004] In view of this, the object of the p...
