A steam system of a double-liner steamer and a detection method for steam valve faults

Abstract

A steam system of a double-inner tank steamer, the steam generator outlet is connected to the steam valve inlet, and the two steam valve outlets are connected to the first inner tank and the second inner tank respectively. The air outlets of the inner tank and the second inner tank are connected with the air inlet of the air guide assembly, a first pressure switch is installed on the pipeline between the steam generator and the steam valve, and a pressure switch is installed between the steam valve and the first inner tank. A second pressure switch is installed on the pipeline, and a third pressure switch is installed on the pipeline between the steam valve and the second inner tank. The double-liner steamer can detect whether the steam valve is blocked in real time. When the steam valve is blocked, the first pressure switch will feed back an electrical signal and cut off the power supply of the steam generator. The control panel will display a fault prompt indicating that the steam valve is blocked. When the two inner tanks work alone, both the second pressure switch and the third pressure switch work. At this time, the electric signal is fed back, the power supply of the steam generator is cut off, the heating is stopped, and a fault prompt indicating that the steam valve is not tightly sealed is displayed on the control panel.

Description

technical field [0001] The invention relates to a double-liner steamer, in particular to a steam system of a double-liner steamer and a steam valve fault detection method thereof. Background technique [0002] The steam generator is one of the essential parts of the existing household appliances with steaming function. Taking the steam box frequently used in the household kitchen as an example, the steam box includes a water tank, a steam generator, a steam heater and a drum. Wind device and other units. Existing steam generators generally include a base and a heating assembly installed on the outer surface of the base. The heating assembly heats the water inside the base to generate steam, and the generated steam flows out of the steam generator and enters the cooking inner tank to affect the food. for heating. [0003] At present, in a double-liner layered steamer or a steamer oven, a steam generator and a steam valve structure are usually used. The steam valve independe...

AI Technical Summary

Problems solved by technology

[0003] At present, in a double-liner layered steamer or a steamer oven, a steam generator and a steam valve structure are usually used. The steam valve independently controls the opening and closing of the two steam channels. When the channel is opened and the other channel is closed, the steam valve may be blocked or not sealed. When it is blocked, the air pressure in the steam generator will increase sharply, and the connection to the water inlet pipe will collapse, posing a safety hazard. Failure to do so will cause steam to leak into another liner, affecting product performance and user experience
