Problems solved by technology

However, the combustion effect of gas water heaters will be limited by the gas supply conditions of users' homes. Some users' homes may have problems with gas water heaters not working properly due to insufficient gas supply pressure of the overall pipe network or insufficient gas supply during peak gas consumption, affecting hot water production. The speed and user bathing experience
[0003] At present, the maximum gas pressure in my country is about 3000Pa, but the gas pressure is seriously insufficient during the peak gas consumption, which will inevitably cause the following problems: First, the gas pressure may be lower than 1000Pa during the peak gas consumption, resulting in the failure of the gas water heater to start normally; The working principle of gas water heaters, low air pressure directly affects the speed of hot water outlet; third, the poor stability of air pressure affects the stability of outlet water temperature, which will be directly felt by users during use, greatly affecting user experience
[0004] At present, there are no related gas booster water heater products in the market. When the pressure is low, the ratio of gas to air is only adjusted by controlling the proportional valve, and the pressure stability of the gas behind the proportional valve is improved by increasing the opening of the proportional valve. The effect of this method is very limited when the pressure is below 1000Pa

Embodiment 1

[0038] Such as figure 1 As shown, this embodiment provides a control method for a pressurized gas water heater. The gas water heater includes a gas booster device 4 arranged on the gas intake pipeline 3. After the gas water heater is started, the gas booster device 4 is controlled according to whether the ignition is successful. On / off, pressurization of gas on / off.

[0039] In this embodiment, the gas water heater with supercharging function includes a heat exchange device, a combustion chamber 2, and a gas intake pipeline 3. The heat source, the water in the heat exchange device flows out from the water outlet after heat exchange, and is used for bathing by users.

[0040] The gas intake pipeline 3 is provided with a gas booster 4, which can boost the gas. The gas pressurizing device 4 may include various types, and it only needs to be able to pressurize the gas in the gas intake pipeline 3 . For example, the motor 41 may drive a supercharging device, or may be a turbocha...

Embodiment 2

[0060] This embodiment is a further limitation of Embodiment 1. The pressurized gas water heater of this embodiment includes a control device 1, a heat exchange device, a combustion chamber 2 and a gas intake pipeline 3, and the gas intake pipeline 3 is connected to the combustion chamber 2. Gas enters the combustion chamber 2 and burns to provide a heat source for the heat exchange device. The gas intake pipeline 3 is provided with an electrically driven gas booster 4 , and the electrically driven gas booster 4 is electrically connected to the control device 1 .

[0061] In this solution, the electric-driven gas booster device 4 is adopted, and the control device 1 can conveniently control the opening, closing, driving parameters, etc. of the electric-driven gas booster device 4, control the boosting effect on the gas, and keep the gas pressure at a relative Within a stable pressure range, the gas water heater can be guaranteed to burn efficiently.

Abstract

The invention discloses a control method of a pressurizing gas water heater and the gas water heater. The gas water heater comprises a gas pressurizing device arranged on a gas inlet pipe. After the gas water heater is started, the gas pressurizing device is controlled to be opened / closed by judging whether or not ignition succeeds, gas is pressurized / gas pressurizing is stopped, after the gas water heater is normally started, ignition is performed first, and if ignition succeeds, the gas water heater normally works. If ignition does not succeed, it is judged that the pressure of gas is low, the gas pressurizing device is controlled to be started, and the gas is pressurized. According to the control method and the gas water heater, the gas inlet pressure and stability can be guaranteed, the optimal burning work condition can be achieved, the water outlet temperature and stability are guaranteed, and the bathing experience of a user is greatly improved.

Description

technical field [0001] The invention belongs to the field of water heaters, and in particular relates to a control method of a pressurized gas water heater and a gas water heater. Background technique [0002] A gas water heater is an instant water heater that burns fuel to transfer heat to water, and is becoming more and more popular among ordinary household users. However, the combustion effect of gas water heaters will be limited by the gas supply conditions of users' homes. Some users' homes may have problems with gas water heaters not working properly due to insufficient gas supply pressure of the overall pipe network or insufficient gas supply during peak gas consumption, affecting hot water production. Speed ​​and user bathing experience. [0003] At present, the maximum gas pressure in my country is about 3000Pa, but the gas pressure is seriously insufficient during the peak gas consumption, which will inevitably cause the following problems: First, the gas pressure...
