Water heater with micro-nano bubble water generating device and control method thereof

Abstract

The invention provides a water heater with a micro-nano bubble water generating device and a control method thereof. The water heater comprises a water heater body and the micro-nano bubble water generating device, the micro-nano bubble water generating device is arranged in the water heater body, and the micro-nano bubble water generating device comprises a jet device, a gas mixing tank, a gas inlet pipe and a water inlet pipe. The water inlet pipe communicates with a water flow pipeline in the water heater body, the water outlet end of the water inlet pipe and the gas outlet end of the gas inlet pipe communicate with the jet device, the water outlet end of the jet device communicates with the water inlet end of the gas mixing tank, and an air pump and a gas flowmeter are further arranged on the gas inlet pipe. A user can select whether to enter the micro-nano bubble water function or not, and the flow of real-time gas entering the gas mixing tank can be obtained.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a water heater with a micro-nano bubble water generating device and a control method thereof. Background technique [0002] Existing water heater products do not have the microbubble washing function themselves, and when the microbubble water generating device is integrated with the water heater, problems such as complex structure and high energy consumption will be faced. Therefore, in order to solve the problem of large operating volume and high power when the dissolved air booster device is applied to a water heater, the way of introducing air into the liquid phase is very important. One is to actively inject high-pressure gas artificially, so that the air pressure in the gas chamber is higher than the water pressure in the water flow chamber; the other is to rely on the principle of throttling and pressure reduction to form negative pressure and automatically inhale gas...

AI Technical Summary

Problems solved by technology

High-pressure gas source is not easy to obtain, and at the same time, it is noisy, low utilization rate and has potential safety hazards; from the perspective of operating energy consumption, negative pressure suction reduces the energy consumed to increase the gas pressure, and is easy to implement

However, since the gas enters into a negative pressure state, the state of the gas is related to temperature and pressure, so the gas flow cannot be directly measured, and the mass flow or standard volume flow of the gas needs to be compensated for temperature and pressure. Real-time flow, it is difficult to ensure the mixing effect of gas and liquid in the gas mixing tank, it is difficult to ensure the oxygen concentration in the micro-nano bubble water, and it is difficult to guarantee the user's effect
