Water flow control method and gas water heater

Abstract

The invention discloses a water flow control method and a gas water heater, wherein the water flow control method comprises the steps that Step 1, inlet flow detected by a water flow sensor is obtained; Step 2, a water supply flow range A is calculated to determine whether the inlet flow is within the water supply flow range A; if a judgment result is yes, a water pump is not started; if the judgment result is no, process proceeds to Step 3; Step 3, the water pump is started, and the inlet flow is adjusted to the water supply flow range A by the water pump. According to the gas water heater, the inlet flow is adjusted to the water supply flow range required by users through the water pump, so that user requirements of a water temperature can be fulfilled when water flows out of a water outlet of the gas water heater regardless of a water pressure at a water inlet, thereby avoiding the problem that the water temperature at the water outlet of the gas water heater always changes along with the inlet flow and further increasing the usage requirements of users.

Description

technical field [0001] The invention belongs to the field of water heaters, and in particular relates to a water flow control method and a gas water heater. Background technique [0002] At present, in daily life, there is generally insufficient water supply, which cannot meet the bathing requirements of users, especially during the peak water consumption period, and there will also be insufficient water supply in cities. Insufficient water supply pressure often causes gas water heaters to fail to start, or after starting If the water flow is small, it will affect the user's use. [0003] In addition, sometimes the water flow fluctuates greatly, and the water volume rises during bathing, resulting in low water temperature, which cannot meet the bathing needs of users. [0004] Although the gas water heaters currently on the market can be started at low water pressure, the water flow is too small to meet the requirements for bathing. In this case, a water-gas linkage valve i...

[0002] At present, in daily life, there is generally insufficient water supply, which cannot meet the bathing requirements of users, especially during the peak water consumption period, and there will also be insufficient water supply in cities. Insufficient water supply pressure often causes gas water heaters to fail to start, or after starting The water flow is small, which will affect the user's use

[0003] In addition, sometimes the water flow fluctuates greatly, and the water volume rises during bathing, resulting in low water temperature, which cannot meet the bathing needs of users.

[0004] Although the gas water heaters currently on the market can be started at low water pressure, the water flow is too small to meet the requirements for bathing. In this case, a water-gas linkage valve is generally used to connect the water pump. Although this method can increase However, turning off the water pump after reaching its pressure will cause the water flow to drop suddenly, and restarting the water pump will cause the water pressure to rise suddenly, resulting in the situation where the water flow fluctuates and the water temperature fluctuates.
