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, the present embodiment provides a pressurized gas water heater, including a combustion chamber 2 and a gas intake pipeline 3, the gas intake pipeline 3 is connected to the combustion chamber 2, and the gas enters the combustion chamber 2 for combustion, and also includes a The turbocharger 4 on the gas intake pipeline 3, the exhaust gas pipeline 5 is arranged between the combustion chamber 2 and the turbocharger 4, the exhaust gas in the combustion chamber 2 enters the turbocharger 4 through the exhaust pipeline 5 and drives The turbocharger 4 operates to supercharge the gas.

[0039] In this embodiment, the gas water heater with pressurization function includes a heat exchange device 7, a combustion chamber 2, and a gas intake pipeline 3, the gas intake pipeline 3 is connected to the combustion chamber 2, and the gas enters the combustion chamber 2 and burns to form a heat exchange device 7 Provide heat source. Pass water such as tap water or...

Embodiment 2

[0056] Such as figure 2 As shown, this embodiment is a further limitation of Embodiment 1, and provides a control method for a supercharged gas water heater. The gas water heater controls the flow direction of the exhaust gas according to the pressure value of the gas detected by the gas pressure detection device 8, and controls the turbocharging. The opening / closing of the device 4 carries out / stops pressurizing the gas. In this way, the energy of the exhaust gas can be used again, and the pressure of the intake gas can be accurately controlled to ensure the stability of the gas intake pressure. It is suitable for various combustion conditions, ensures the temperature and stability of the outlet water, and greatly improves the user's bathing experience.

[0057] Specific programs include:

[0058] When the gas pressure detection device 8 detects that the real-time intake gas pressure value N is lower than the preset value N1, it transmits a signal to the control device 1, a...

Abstract

The invention discloses a pressure boost gas water heater and a control method. The pressure boost gas water heater comprises a burning cavity and a gas inlet pipeline. The gas inlet pipeline is connected with the burning cavity, and gas enters the burning cavity to burn. The pressure boost gas water heater further comprises a turbo-charging device which is disposed on the gas inlet pipeline; a waste gas pipeline is disposed between the burning cavity and the turbo-charging device; and waste gas in the burning cavity enters the turbo-charging device through the waste gas pipeline and drives the turbo-charging device to run, and pressure boost is performed on the gas. According to the pressure boost gas water heater, the turbo-charging device is driven by the waste gas, pressure boost is performed on the gas when the gas pressure is low, the gas inlet pressure and stability can be guaranteed, thus the effect that the optimum burning condition is obtained is guaranteed, the outlet watertemperature and stability are guaranteed, and the washing and 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 pressurized gas water heater and a control method. 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 may be lower than 100...
