Flow quantity control method for improving user experience and gas water heater

Abstract

The invention relates to the technical field of gas water heaters, in particular to a flow quantity control method for improving user experience and a gas water heater using the method. The flow quantity control method comprises the following steps that a demanded water flow quantity numerical value of a user is obtained; and a rotation speed of a water pump motor is controlled so as to adjust thewater outflow quantity according to the demanded water flow quantity numerical value of the user. According to the flow quantity control method, the user sets a water flow quantity value through a control panel according to demands, after the water flow quantity value set by the user is transmitted to a controller, the controller controls the rotation speed of the water pump motor according to the water flow quantity value set by the user, so that the flowing-out water flow quantity conforms to the water flow quantity set by the user, accordingly a comfortable water usage environment is provided for the user, and the user experience is improved. The gas water heater can adjust the water outflow quantity according to the demands of the user, it is ensured that the water outflow quantity isconstant, the situation that the water temperature is hot and cold suddenly because the water flow quantity is suddenly large and small in the water using process cannot happen, and accordingly the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of gas water heaters, in particular to a flow control method for improving user experience and a gas water heater using the method. Background technique [0002] When the current water pump transports liquid, its flow rate is generally fixed, but in real life, some discharged liquid does not require a higher flow rate, which wastes energy and resources, and if the water pump with low kinetic energy is replaced To save energy, on the one hand, different water pumps need to be replaced according to different needs, which is time-consuming and laborious; on the other hand, different water pumps need to be prepared, which requires a lot of investment. [0003] For example, during the use of the water heater, a booster pump needs to be added to satisfy the work of the gas water heater and to provide users with water comfort, but the water flow may be too large after the booster pump is running, resulting in the t...

[0002] When the current water pump transports liquid, its flow rate is generally fixed, but in real life, some discharged liquid does not require a higher flow rate, which wastes energy and resources, and if the water pump with low kinetic energy is replaced To save energy, on the one hand, different water pumps need to be replaced according to different needs, which is time-consuming and laborious; on the other hand, different water pumps need to be prepared, which requires a lot of investment

[0003] For example, during the use of the water heater, a booster pump needs to be added to satisfy the work of the gas water heater and to provide users with water comfort, but the water flow may be too large after the booster pump is running, resulting in the temperature of the heated water not reaching the preset value. The temperature will lead to poor user experience, and it will also cause water waste
