Problems solved by technology

In the supercharged working state, after the user turns off the bath faucet, the tap water stops flowing into the water heater, but the built-in water pump keeps running, and the return flow of hot water is greater than the shutdown flow of the program, and the water heater automatically switches to the cycle preheating mode, thus consuming too much gas and electricity , causing unnecessary waste, and when hot water is used again, the water temperature is too hot

Embodiment 1

[0047] Embodiment 1 of the present invention provides a zero cold water gas water heater with circulation restriction, such as figure 1 As shown, it includes a gas water heater body 1, a water pump 2, a water flow sensing component 3, a return water temperature detection component 4, an operation display 5, a controller 6 and a one-way steady flow component 7, and the water pump 2 and the water flow sensing component 3 are installed in On the main waterway 11 in the gas water heater body 1, the return water temperature detection assembly 4 is installed at the water inlet end of the main waterway 11, the water pump 2, the water flow sensing assembly 3, the return water temperature detection assembly 4 and the operation display 5 are all It is electrically connected with the controller 6 , and the one-way steady flow assembly 7 is installed on the circulating return water pipeline 12 outside the gas water heater body 1 .

[0048]In this way, the tap water enters the main waterwa...

Embodiment 2

[0067] like Figure 5 As shown, Embodiment 2 of the present invention provides a method for preheating control of a zero-cold water gas water heater based on the circulation-limited flow, including the following steps:

[0068] S1. The gas water heater is in standby mode, start the preheating function, turn on the water pump, detect the real-time water flow and compare it with the preset start-up water flow;

[0069] S2. When the real-time water flow rate is not less than the preset start-up water flow rate, start the ignition and switch to the preheating mode, otherwise, send out a fault alarm;

[0070] S3. The gas water heater is in the preheating mode, and the real-time return water temperature is detected and compared with the preset preheating temperature;

[0071] S4. When the real-time return water temperature is not less than the preset preheating temperature, turn off the water pump and exit the preheating mode; otherwise, compare the detected water flow sudden incre...

Embodiment 3

[0082] like Image 6 and 7 As shown, Embodiment 3 of the present invention provides a method for controlling the pressurization of a zero-cooled gas water heater based on the cycle flow limitation, including the following steps:

Abstract

The invention discloses a cycle-limited zero-cold water gas water heater and a preheating and pressurization control method, wherein the cycle-limited zero-cold water gas water heater comprises: a water pump and a water flow sensing component are installed on the main waterway in the body of the gas water heater, The return water temperature detection component is installed at the water inlet end of the main waterway. The water pump, water flow sensing component, return water temperature detection component and operation display are all electrically connected to the controller. The one-way steady flow component is installed on the circulating return pipe outside the gas water heater body. on the way. The zero-cold water gas water heater with circulation and flow limitation of the present invention detects the real-time water flow through the water flow sensing component, so that the pump can be turned off quickly after the hot water is turned on, reducing the power consumption of the water pump, and the pump can be turned off quickly after the hot water is turned off, reducing gas consumption. , Power consumption, when water is used again, the water temperature will not be too hot. At the same time, a one-way steady flow component is installed in the circulating return water pipeline to limit the circulating flow, increase the real-time water flow, and improve the accuracy of program monitoring.

Description

technical field [0001] The invention belongs to the technical field of gas water heaters, and in particular relates to a cycle-limited zero-cold water gas water heater and a preheating and boosting control method. Background technique [0002] At present, zero-cold water gas water heaters have become the trend of the water heater industry because they can realize instant hot water, and are more and more popular among consumers. A water pump, a water flow sensing component and a return water temperature detection component are arranged in the internal main water circuit of the conventional zero-cooled water gas water heater. After starting the preheating function, the built-in water pump runs to drive the water circulation of the hot water pipe and the return pipe for preheating. During the preheating process, when the return water temperature reaches the programmed preheating temperature, turn off the water pump and exit the preheating. When actually using a zero-cold wate...
