Problems solved by technology

However, there are still some problems. For example, when the water proportional valve controls the water flow, it can only reduce the water flow as required, and the minimum temperature rises, because the water comfort cannot be guaranteed.

Abstract

The invention discloses a gas water heater comprising a gas ratio valve, a water ratio valve which adjusts the water level, a pump, a flow sensor, a temperature sensor and a controller. The pump is arranged on a water incoming pipeline of the gas water heater and is used for adjusting the flow; the flow sensor is used for detecting the incoming flow; the temperature sensor is used for detecting the discharged water temperature; the controller is used for controlling the water ratio valve, the gas ratio valve and the pump to adjust the temperature of flow of the discharged water according to the discharged water temperature and the incoming flow. The flow of the gas water heater can be adjusted, used water temperature is guaranteed, and comfort is improved. The invention further provides a control method of the gas water heater.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a gas water heater and a control method for the gas water heater. Background technique [0002] With the rapid development of water heaters, users' requirements for the comfort of water heaters are constantly increasing. In order to ensure the requirements of the outlet water temperature, it can be realized by using the constant temperature of the gas proportional valve and the constant temperature of the water proportional valve. Under the conditions of sufficient water and sufficient air, the constant temperature requirement can be fully achieved. However, in places where there is a shortage of water, the outlet water temperature is often too high due to the excessive minimum load, making it unusable. Moreover, the water pressure is low and the water is scarce, which seriously affects the comfort of use. [0003] In addition, most domestic enterprises have developed water...
