An abnormality detection method for a steam system

Abstract

The invention discloses an abnormal detection method of a steam system, comprising: S1: start the steam program, and start timing; S4: start the heating module, and judge whether there is water in the evaporator; S5: judge whether the running time t1 reaches the preset time ts1 ;S6: Supply water to the evaporator, and judge whether there is any abnormality in the water circuit after stopping the water supply; S7: Maintain the steam program until the end; S8: Supplement water to the evaporator, and judge the internal temperature of the evaporator and the second preset temperature within a certain period of time Ts2 relationship to determine whether there is an abnormality in the waterway. The abnormality detection method of the steam system of the present invention, through the cooperation of the temperature detection module and the controller, can directly determine whether the waterway of the steam system is abnormal, and report an error when an abnormality occurs. The detection accuracy of the abnormality of the waterway is high and the reliability is strong. The overall structure of the steam system can be simplified and the manufacturing cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an abnormality detection method of a steam system. Background technique [0002] The steam system of the steam oven is composed of water tank, water pipe, water pump, solenoid valve, evaporator, and temperature sensor in the evaporator. If there is any abnormality in any part, it may directly lead to the inability to output steam, which will lead to the failure of the steaming function. In order to ensure the normal operation of each component, the traditional method is to add a detection circuit to each component. For example, to detect whether the water tank is in place, a water tank position switch can be added, and to detect whether there is water in the water tank, a dry reed switch can be added to detect whether there is water in the water tank. The magnetic float can be used to detect the abnormality of the solenoid valve and the water pump, and the current de...
