Solar water heater hot-water discharging steady pressure controller

Abstract

The invention relates to the technical field of solar water heaters, in particular to a solar water heater hot-water discharging steady pressure controller. According to the solar water heater hot-water discharging steady pressure controller, a water outlet of a water tank is connected with a hot water valve through a water discharging pipe, a pipeline of the water discharging pipe is provided with a water flow sensor and a water pump, the water flow sensor and the water pump are connected with a control module through control lines respectively, and start and stop of the water pump are controlled through the control module according to water flow signals; when the water flow sensor internally continuously transmits hot water turning-off signals for n times, a water pump stopping signal istransmitted by the control module, and otherwise, the control module keeps continuously transmitting water pump starting signals; and the sampling frequency of the control module aiming at the waterflow signals is K times / min, wherein K and n are natural numbers larger than 1, and K is larger than or equal to n. According to the solar water heater hot-water discharging steady pressure controller, the start and the stop of the water pump are optimally controlled through the control module, the effects that hot water is pressurized and false action shutdown is not conducted are achieved, the using comfort of the pressurized hot water is improved, and the technical difficult problem that water temperature adjustment is difficult when the hot water flow is small is solved.

Description

technical field [0001] The present invention relates to a voltage stabilizing controller for liquid outflow boosting, in particular to a solar water heater hot water outflow stabilizing controller, which belongs to the field of water heater equipment, but is also applicable to cold water and various liquid outflow boosting and voltage stabilizing controls. At present, it is mainly used in the technical field of voltage stabilizing controller equipment for solar hot water outflow boosting. Background technique [0002] There are two types of solar water heaters in terms of pressure: 1. Closed type - pressurized solar water heaters use tap water pressure to produce hot water from the top (same as electric water heaters), and communicate with the user's water supply pipes through pipes , The hot water pressure is the tap water pressure. This kind of product has high cost and low water yield, and its market share in China is not high. 2. Open type - the non-pressurized solar wa...
