Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gas water heaters, and more particularly to a gas bubble tank and a micro-bubble gas water heater. BACKGROUND

[0002] Micro-nano bubbles are bubbles with a diameter of less than 100 microns, which have the properties of long existence time, high gas-liquid mass transfer rate, high surface potential, and good air floatation effect. Micro-nano bubble technology is currently widely used in water purification, environmental governance, beauty and skin care, fruit and vegetable cleaning, and other fields. The industrial production methods include dispersed air method, electrolysis method, alcohol-water replacement method, ultrasonic cavitation method, chemical reaction method, and micro-pipe method. The commonly used micro-bubble generation methods in the field of gas water heaters are water tank type pressurized gas dissolution method and water pump type pressurized gas dissolution method. For example, scheme one: Chinese patent application No. 201910913885.7 discloses a water heater. When the air in the water tank is consumed, the user manually closes the water outlet end and then opens the water outlet end. At this time, the water inlet end stop valve of the water tank is closed, the air pump connected to the water tank starts to work, the air is added to the preset value, the water inlet stop valve of the water tank is opened, and the micro-bubbles continue to be generated. Scheme two: Chinese patent application No. 202011466494.4 discloses a micro-bubble water heater. The water heater uses a gas dissolution pump and a degassing tank to cooperate. The gas dissolution pump extracts air and pressurizes and dissolves the air in the pump. The degassing tank discharges the undissolved excess air, and outputs water that can generate micro-bubbles. Scheme one has the following problems: the gas bubble tank requires a high water flow rate, so a large water pressure or a small water inlet is needed to increase the flow rate. Some users cannot meet the requirement of high water pressure, and the gas dissolution effect is poor. A small water inlet will reduce the flow rate of the whole machine and affect the bathing experience. Scheme two has the following problems: the water pump requires a high requirement, the water pump has a large noise, high power, large power consumption, and high production cost. The degassing tank cannot completely remove large bubbles, resulting in water containing large bubbles. Therefore, it is necessary to improve the existing technology and develop a gas bubble tank with lower cost and smaller size and a corresponding water heater. SUMMARY

[0021] The specific embodiments of the present application are further described below with reference to the accompanying drawings, so that the technical scheme of the present application and its beneficial effects are more clear and explicit. The description of the embodiments below by referring to the accompanying drawings is exemplary and is intended to explain the present application, and cannot be understood as a limitation of the present application.

[0022] As shown in Figs. 1-2 The present application is a dissolved air tank and a micro-bubble gas water heater with switchable flow mode, and the dissolved air tank is applied to the micro-bubble gas water heater. In structure, the dissolved air tank comprises a tank body 1 and a water baffle 2 arranged in the tank body 1. The tank body 1 is provided with a small-hole water inlet 1-1, a large-hole water inlet 1-2 and a water outlet 1-3. The tank body 1 is vertically arranged, the small-hole water inlet 1-1 and the large-hole water inlet 1-2 are arranged side by side at the top of the tank body 1, and the water outlet 1-3 is arranged at the bottom of the tank body 1. The hole diameter of the small-hole water inlet 1-1 is φ5mm, and the hole diameter of the large-hole water inlet 1-2 is φ10mm. The water baffle 2 of the dissolved air tank has the following functions: the water inlet injects air into the water below the tank body, and part of the large bubbles cannot float up in time and will flow out of the water outlet with the water flow, resulting in poor endurance of the dissolved air tank and large bubbles mixed in the water. The addition of the baffle can make the large bubbles float up quickly and reduce the loss of bubbles.

[0023] The switchable flow mode micro-bubble gas water heater comprises a water heater body 3, a heat exchanger part 4, a burner 5, a gas pump 6, a gas check valve 7, a first stop valve 8, a second stop valve 9 and a gas tank 10. The water inlet pipe 11 connected with the external water pipe is connected with the water inlet end of the heat exchanger part 4, the gas inlet pipe 12 is connected with the burner 5, the water outlet end of the heat exchanger part 4 is connected with the hot water pipe 13, the first stop valve 8 is arranged on the hot water pipe 13, the gas pump 6 and the gas check valve 7 are connected with the hot water pipe 13 through pipes, the gas pump 6 is connected with the hot water pipe 13 through the gas check valve 7, the gas flow direction of the gas check valve 7 is from the gas pump 6 to the gas tank 10, the hot water pipe 13 is provided with a first hot water branch 14 and a second hot water branch 15, the first hot water branch 14 is connected with the small hole water inlet 1-1 of the gas tank, the second hot water branch 15 is connected with the large hole water inlet 1-2, and the second stop valve 9 is arranged on the second hot water branch 15. The water outlet 1-3 of the gas tank is connected with the water heater outlet pipe 16, and the terminal switch valve 17 and the bubble shower 18 are arranged on the water heater outlet pipe 16.

[0024] In the conventional state of the water heater, the first stop valve and the second stop valve are in the open state, and at this time, the water flow is maximum.

[0025] In the bubble water state of the water heater, the first stop valve is opened, and the second stop valve is closed, at this time, the water flow rate of the water inlet end of the gas tank is improved, the gas dissolving effect is improved, and the gas dissolving water with a high gas dissolving amount can be output.

[0026] After the bubble water state of the water heater is continuously used for a period of time, the bubble water effect becomes poor, at this time, the first stop valve is closed, the second stop valve is opened, and the gas pump starts to work until the water in the gas tank is exhausted. After the gas tank is exhausted, the state of the water heater is the bubble water state, and the gas dissolving water is continuously generated.

[0027] Since the existing gas tank needs water flow rate to generate bubble groups, under the condition of low water pressure, the large inlet hole diameter will affect the water flow rate, and the gas flow generated by the injection will be reduced, and the gas dissolving effect will be poor. However, the small inlet hole diameter will also cause the flow rate of the whole machine to decrease, and the user's bathing experience will be affected, so the double water inlets are arranged to switch the flow mode. In the bubble water mode, the single small hole water inlet is used; in the conventional large flow mode, the double hole water inlet is used.

[0028] Compared with the prior art, the gas tank of the present application has a small volume and a simple structure, and the flow mode can be freely switched by cooperating with the stop valve. The gas tank is provided with a water baffle, which can make the large bubbles float rapidly and reduce the loss of bubbles. In the bubble water state of the whole micro-bubble generating system of the water heater, the gas dissolving effect is improved, and the gas dissolving water with a high gas dissolving amount can be output.

[0029] The above merely describes the preferred embodiments of the present application, and it should be noted that, for those skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which all belong to the protection scope of the present application.
