Control method and system for open heat storage tank of electronic closestool

Abstract

The invention discloses a control method and system for an open heat storage tank of an electronic closestool. The control system comprises a water tank, a water inlet valve, a water suction pump, a liquid level sensor, a heating device and a main control panel. The liquid level sensor is used for detecting the water level in the water tank, and the main control panel is used for controlling the water inlet valve, the water suction pump and the heating device to operate according to the detection result of the liquid level sensor, wherein when the liquid level sensor detects that the water level in the water tank reaches a full water level L1, the water inlet valve is controlled through the main control panel to close so that water injection to the water tank is stopped; when the liquid level sensor detects that the water level in the water tank falls to the make-up water level L2, the water inlet valve is controlled through the main control panel to open so that water is injected to the water tank; and when the liquid level sensor detects that the water level in the water tank falls to the low water level L3, the water suction pump is controlled through the main control panel to stop pumping water from the water tank. According to the control system, the service life of the heating device can be prolonged, and the water temperature fluctuation in the water tank is reduced greatly; and the user experience is improved.

Description

technical field [0001] The invention relates to a control method and a control system of an open heat storage tank of an electronic toilet. Background technique [0002] Nowadays, electronic toilets are more and more accepted by users. It heats tap water to flush human body parts. In related technologies, electronic toilets have various heating methods for flushing water, mainly including instant heating and storage. The thermal heating method usually installs a heating device in the water tank. The water tank is basically closed, and the water inlet and outlet of the water tank are connected. In this way, the outlet water pressure is greatly affected by the change of the inlet water pressure, which affects the user. use experience. [0003] In order to solve the above problems, in the prior art, an open water tank is used to isolate the water inlet and outlet of the water tank, and the heated water in the water tank is pumped out by a pump to wash the body parts, thereby s...

Problems solved by technology

[0004] But the problem that the open water tank exists at present is: the water in the water tank can't be supplemented in time when not enough, and can overflow again when the water in the water tank is many

This will often damage the heating device in the water tank, resulting in a shorter service life of the heating device, and it will also increase the fluctuation of the water temperature, affecting the user experience
