s2: the water scale crushed by the ultrasonic cleaning device is discharged into the first inner container from the bottom of the second inner container and discharged through the first drain outlet at the bottom of the first inner container, so that the water scale is cleaned.
The step S1 includes a start signal generated when the user manually starts or an automatic start signal sent by the detection device.
The automatic starting signal sent by the detection device can be a starting signal sent by detecting that the turbidity of water reaches a preset turbidity value; the method can be a starting signal sent by detecting that the flow of water reaches a preset flow value; the method can be that a starting signal sent by detecting that the heating time reaches the preset time; or a combination of the two or the three.
Specifically, the water heater scale cleaning method provided by the scheme comprises the following steps: the water enters the first inner container through the water inlet, directly enters the second inner container through the filtering holes of the second inner container, the water is heated by the heating device, the heated water is discharged from the filtering holes of the second inner container into the first inner container, large-particle scale is intercepted in the second inner container, the effect of effective water and scale separation is achieved, the water discharge speed of the filtering holes at the upper part is greater than that of the filtering holes at the lower part, and the water discharged into the first inner container flows into the hot water pipe through the water outlet for use.
After a period of use, a user turns on the ultrasonic cleaning device; or, when the turbidity sensor detects that the turbidity of the water reaches a preset turbidity value, and/or the flow sensor detects that the flow of the water reaches a preset flow value, and/or the time detection device detects that the heating time of the water reaches a preset time, the ultrasonic cleaning device is started, and the ultrasonic waves can cover the whole area in the first liner, especially the position of the filtering part.
Most of the water scale crushed by the ultrasonic cleaning device is discharged into the first inner container from the second sewage outlet at the bottom of the second inner container, and a small amount of the water scale is discharged from the filtering holes below the second inner container, so that the water scale treated by the ultrasonic is in a powder shape, is easy to discharge and prevents blockage; finally, the scale is discharged through a first drain outlet at the bottom of the first inner container, and self-cleaning and regular cleaning of the scale are completed.
In addition, the water inlet speed of the first inner container and the second inner container is kept to be larger than the water outlet speed, so that the first inner container and the second inner container are kept full of water all the time, and the water is given enough heating time.
The foregoing description is only illustrative of the preferred embodiment of the present application, and is not to be construed as limiting the application, but is to be construed as limiting the application to any simple modification, equivalent variation and variation of the above embodiments according to the technical matter of the present application without departing from the scope of the application.
