Water outlet temperature adjusting device, air source water heater and method for automatically adjusting outlet water temperature

Abstract

The invention discloses an outlet water temperature adjusting device, an air energy water heater and an automatic outlet water temperature adjusting method. The outlet water temperature adjusting device comprises a controller, a water tank and an electronic constant-temperature water mixing valve. The electronic constant-temperature water mixing valve is connected with the controller, a hot water inlet end of the electronic constant-temperature water mixing valve is connected with a hot water outlet end of the water tank, and a cold water inlet end of the electronic constant-temperature water mixing valve is communicated with a cold water feeding pipe of the water tank. The controller is used for obtaining the temperature of water in the water tank, comparing the water temperature with the preset water temperature and sending adjusting instructions for adjusting the opening degree of the hot water inlet end and / or the cold water inlet end to the electronic constant-temperature water mixing valve according to comparison results. The electronic constant-temperature water mixing valve adjusts the opening degree of the hot water inlet end and / or the cold water inlet end according to the opening degree adjusting instructions and controls the outlet water temperature of a water outlet of the electronic constant-temperature water mixing valve. By means of the outlet water temperature adjusting device, water can be output according to the temperature set by a user, the water mixing valve is not needed to be adjusted repeatedly by the user, the outlet water temperature is stable, and the water use comfort level of the user is improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an outlet water temperature adjustment device, an air energy water heater and an automatic adjustment method for the air energy water heater. Background technique [0002] With its excellent performance, air-energy water heaters have attracted more and more attention and use from users. Traditional air-energy water heaters use the method of adding hot water inside the water tank to the temperature set by the user, and then leading the hot water to the designated location through the pipeline. , to achieve the outlet water temperature by manually adjusting the water mixing valve. Because of its unique working principle, air-energy heat pump water heaters cannot be turned on and used 24 hours a day like electric water heaters and gas water heaters. The air energy heat pump water heater is suitable for heating or heating in advance when the energy efficiency is the hig...

Problems solved by technology

During the user's use, with the continuous replenishment of cold water in the water tank, the water temperature in the overall water tank continues to drop, and with the change of water flow and water pressure, the user needs to constantly adjust the water mixing valve to keep the water temperature at a constant state , leading to a decrease in water comfort for users and a waste of water resources
