Background

The gas water heater is used as a household appliance commonly used in life of people, brings great convenience to life of people, and gradually cannot meet the requirements of people along with the increasing requirements of people on sanitation. The micro-bubbles are micro-bubbles with the diameter below 50um, and the micro-bubbles are formed by fully mixing gas (such as air) with water under a certain pressure to form a gas-water mixed solution, and then expanding and releasing the pressure to enable the gas dissolved in the water to be suddenly polymerized to form fine micro-bubbles to be milky. The micro-bubble water formed in the process has strong detergency, and pressure and heat generated when micro-bubbles in the water are broken can be instantaneously eliminated to take away dirt, so that a deep cleaning effect is achieved.

The application of the micro-bubble water can just meet the requirements of people on sanitation. However, the existing gas water heater generally does not have the micro-bubble water generating function, so that various water heaters capable of generating micro-bubble water are disclosed in the prior art, for example, chinese patent application publication No. 202111107808.6 discloses a gas water heater capable of generating micro-bubble water (publication No. CN 114992842A); reference may also be made to the Chinese patent application publication No. 201910913885.7 for water heater (publication No. CN 110567147A) and the Chinese patent application publication No. 202111493378.6 for bubble water generator for gas water heater (publication No. CN 114198899A).

The existing bubble washing technology has the advantages that an air pump is used or not used, the purpose of the air pump is to dissolve more air in water, so that more air is more convenient to dissolve when the air is injected, the excessive air can enable the pipeline or the water storage tank to bear more air pressure, the requirement on the strength of the pipeline and the water storage tank is high, and the risk of leakage exists.

The function is realized:

the IPSE material can be used for purifying water, and the incoming water is used for purifying water by flushing a filter screen and blades of the IPSE material. Due to the material properties of IPSEs, the more intense the turbulence, the better the cleaning action. The double layer filter device is beneficial to providing water purifying effect.

The filter screen refines bubbles in water (comprising air in water and air introduced by an air pump) through meshes, the smaller the bubble diameter is, the larger the specific surface area of the bubbles is, the larger the contact area of the air and the water is, the larger the contact area of the water and the purification material is, the chemical reaction speed can be increased, and the water purification efficiency of the purification material is accelerated. The bubble water can improve the water purifying efficiency firstly and the detergency secondly, so as to achieve the deep cleaning effect.

The pressure valve plays a role in overpressure protection. The pressure pipe is used for communicating the cavity at the upper part of the pressure valve with the upper part of the water storage tank and sensing the pressure in the water storage tank, because the internal pressure of the water storage tank can rise along with the injection of gas after a user starts a bubble washing function, and the pressure can also be further increased under the influence of the temperature along with the rising of the temperature of water outlet. After the pressure reaches the critical value (before reaching the set critical value, the closing of the first water inlet pipe is not triggered, because the proper pressure helps to improve the dissolution rate of the bubbles), under the action of the pressure of the water storage tank, the first water inlet pipe is gradually closed, and simultaneously the second water inlet pipe is gradually opened, so that the pressure in the water storage tank is ensured not to exceed the safety limit.

The noise reduction sleeve can absorb the noise of a liquid medium or a solid structure in the water mixing tank, and damping noise reduction is realized through self vibration.
