However, the embodiments cited do not limit the present utility model.

It is only for the convenience of describing the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present utility model.

[0027] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element and integrated with it, or there may be an intermediate element at the same time. The terms "installation", "one end", "the other end" and similar expressions used in the present utility model are only for the purpose of illustration.

[0028] This embodiment provides a gas water heater with an ozone sterilization function, as Figure 1 shown, including a main control unit 100, a water circulation pipeline 200 and an ozone generating device 300. The ozone generating device 300 is communicated with the water circulation pipeline 200, and the ozone generating device 300 is communicatively connected with the main control unit 100 for injecting ozone into the water circulation pipeline 200 according to the instruction of the main control unit 100.

[0029] The present utility model realizes ozone sterilization by arranging an ozone generating device 300, communicating the ozone generating device 300 with the water circulation pipeline 200, and communicatively connecting the ozone generating device 300 with the main control unit 100, and then injecting ozone into the water circulation pipeline 200 according to the instruction of the main control unit 100;

[0030] Since ozone can quickly and fully penetrate and diffuse into the water flow, the gas water heater will have a high sterilization efficiency;

[0031] It should be noted that ozone is a strong oxidant and can achieve the sterilization and disinfection effect through biochemical oxidation reactions. Its main sterilization purposes are as follows:

[0032] (1) Ozone inactivates and kills bacteria by oxidizing and decomposing the enzymes required for the internal glucose of bacteria.

[0033] (2) Ozone directly acts on bacteria and viruses, destroys the cell organelles, DNA, and RNA of bacteria and viruses, disrupts the metabolism of bacteria and viruses, and causes their death.

[0034] (3) Ozone penetrates the cell membrane tissue, invades the cell, acts on the lipoproteins and lipopolysaccharides inside the membrane, changes the cell permeability, and causes cell lysis and death.

[0035] Therefore, the ozone generating device 300 achieves the effect of sterilization and disinfection through biochemical oxidation reactions, is non-toxic and harmless, has high safety, and will decompose to produce oxygen, increasing the dissolved oxygen in water and improving the user experience. The water circulation pipeline 200 includes an inlet pipeline 201 and an outlet pipeline 202 that are interconnected. In this embodiment, the ozone generating device 300 is placed in the outlet pipeline 202, and can also be placed in the inlet pipeline 201, that is, it can be set at any position in the water circulation pipeline 200 of the gas water heater.

[0036] In a preferred embodiment, as Figure 2 shown, the ozone generating device 300 includes a controller 301, a booster pump 302, and an electrolysis device 303. The controller 301 is communicatively connected to the main control unit 100, and both the booster pump 302 and the electrolysis device 303 are communicatively connected to the controller 301. The outlet of the electrolysis device 303 is communicated with the water circulation pipeline 200, and the booster pump 302 is communicated with the electrolysis device 303 for pressurizing the ozone generated by the electrolysis device 303 so as to inject it into the water circulation pipeline 200. In this embodiment, the controller 301 receives the instruction issued by the main control unit 100, and generates a first action instruction sent to the electrolysis device 303 and a second action instruction sent to the booster pump 302 according to this instruction. After receiving the first action instruction, the electrolysis device 303 generates ozone. After receiving the second action instruction, the booster pump 302 pressurizes the ozone and injects it into the water circulation pipeline 200 from the outlet of the electrolysis device 303 to perform ozone sterilization and disinfection on the water flow.

[0037] Specifically, the electrolysis device 303 is preferably an air ionization type ozone generator, including an air inlet, an ionization component (not shown in the figure), and an air outlet channel 3031. The ionization component is used to ionize the oxygen molecules in the air entering from the air inlet. The ionization component decomposes the oxygen molecules into free oxygen atoms through high-voltage discharge. Some of the free oxygen atoms will recombine with the undissociated oxygen molecules to generate ozone. The working outlet of the booster pump 302 is communicated with the air outlet channel 3031 to pressurize the ozone in the air outlet channel 3031. Further, the booster pump 302 is an air pump, and injects the generated gas with a certain pressure into the water circulation pipeline 200 together with the ozone in the air outlet channel 3031.

[0038] In a preferred embodiment, as Figure 1 shown, a one-way valve 4 is provided between the ozone generation device 300 and the water circulation pipeline 200 to prevent the water flow from flowing reversely into the ozone generation device 300 and damaging it.

[0039] In a preferred embodiment, the water circulation pipeline 200 includes the zero cold water circulation pipeline 203 of the gas water heater. The ozone generation device 300 is communicated with the zero cold water circulation pipeline 203 and is used to inject ozone into the zero cold water circulation pipeline 203 after the zero cold water function of the gas water heater is started. After receiving the command signal to start the zero cold water function, the main control unit 100 will send a start command to the ozone generation device 300 to control the ozone generation device 300 to operate to generate ozone and inject ozone into the circulating water.

[0040] In another preferred embodiment, as Figure 1 shown, the water outlet pipeline 202 is communicated with the ozone generation device 300. The water outlet pipeline 202 is provided with a visual transparent area. Since ozone is a light blue gas, in this embodiment, by setting the transparent area, the effect of ozone sterilization can be visually displayed, which is convenient for users to visually detect and perceive this function and can improve the user experience. Of course, in another embodiment, the water inlet pipeline 201 can also be communicated with the ozone generation device 300, and the water inlet pipeline 201 is provided with a visual transparent area. The above-mentioned "visualization" means that users can directly view it when using the gas water heater in daily life.

[0041] Furthermore, a water pump 1 is provided in the water circulation pipeline 200. It can be understood that, as Figure 1 shown, the water flow is divided by the three-way valve 2 into a first branch that flows out to the water use port 3 after being heated by the heat exchanger 5 in the water heater 6 and a second branch that directly flows out to the water use port 3. Among them, the zero cold water circulation pipeline 203 is communicated with the pipeline of the second branch, and a water pump 1 is provided in the pipeline of the first branch. At this time, the water pump 1 can be used to realize the zero cold water function of the gas water heater and can also be used to ensure the heating amount of the gas water heater.

[0042] In this specification, unless otherwise clearly specified and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "below" and "beneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.
