Description

Technical Field

[0001] The utility model belongs to the technical field of clothing care, and in particular relates to a sterilization and deodorization device for an electric water heater. Background Art

[0002] In people’s normal home living environment, the bathroom (or toilet) is relatively humid, which makes it easy for bacteria and fungi (such as Escherichia coli, Shigella, Salmonella, Staphylococcus aureus, etc.) to breed. These bacteria and fungi will also produce odor (such as wet odor) when decomposing substances.

[0003] Most bathrooms (or toilets) will install electric water heaters to provide hot water for users to wash and bathe. After daily washing and bathing, the air humidity will increase significantly, and the temperature will become relatively mild, which is more conducive to the reproduction of bacteria and fungi and the generation of odor. Being in such an environment for a long time will not only seriously affect the daily living experience, but also pose potential risks to the user's health (commonly causing inflammation and allergic reactions). In addition, the relatively small space of the bathroom (or toilet) and the presence of many narrow spaces make it difficult to effectively deal with bacteria and odors.

[0004] Currently, most sterilization and deodorization methods use chemical reagents or large ozone generators. Chemical treatment requires manual use of bactericides, deodorants and other chemical reagents (such as disinfectants, air fresheners, etc.) for sterilization and deodorization. Chemical reagents are applied to the sterilization area of ​​the bathroom (or toilet) with a rag or sprayed on the sterilization area with a spray device. Some users also place air fresheners to cover up the odor in the air.

[0005] However, the use of chemical reagents or large ozone generators is not suitable for home users. Neither the chemical sterilization and deodorization method nor the large ozone generator can automatically and timely sterilize and deodorize when bacteria and fungi multiply and produce a lot of odor after the user washes and bathes. In addition, the chemical sterilization and deodorization method uses a higher concentration of bactericides or deodorants, while large ozone generators generate high concentrations of ozone. Both methods may cause slight damage to the human body.

[0006] Therefore, a new sterilization and deodorization device for electric water heater is proposed now. Utility Model Content

[0008] In order to solve the above technical problems, the present disclosure provides a sterilization and deodorization device for an electric water heater, comprising:

[0009] A housing, wherein the housing has a containing space and an air inlet and an air outlet;

[0010] A light tube, the light tube is arranged in the accommodating space, and the light tube is used to generate ozone;

[0011] An air circulation unit is disposed in the accommodating space and is used to accelerate the flow of air inside the shell so that the air containing ozone in the shell flows out.

[0012] Furthermore, the light tube is arranged at the air outlet, and the air circulation unit is located above the light tube.

[0013] Further, the air circulation unit includes a fan.

[0014] Furthermore, the wavelength of the light tube includes 185 nanometers.

[0015] Furthermore, the air inlet is a trumpet-shaped structure.

[0017] Furthermore, the light tubes are arranged alternately with the air inlets and the air outlets, so that the light tubes will not directly irradiate the outside of the shell.

[0018] The disclosed embodiment proposes a sterilization and deodorization device for an electric water heater, which adopts a light tube to generate ozone, and uses a fan to blow the air containing ozone into the external environment.

[0029] At present, the sterilization and deodorization methods of bathrooms (or toilets) are mostly to use chemical reagents or large ozone generating devices. Chemical treatment requires manual use of chemical reagents such as bactericides and deodorants (such as disinfectants, air fresheners, etc.) for sterilization and deodorization. Chemical reagents are applied to the sterilization area of ​​the bathroom (or toilet) with a rag or sprayed on the sterilization area with a spray device. Some users also place air fresheners to cover up the odor in the air. Therefore, the present disclosure provides a sterilization and deodorization device for electric water heaters. The device can be installed on the electric water heater and can be turned on and used at any time. It uses one or more light tubes to generate ozone. The effect is continuous and effective and will not damage the safety of the user's body.

[0030] Please refer to Figure 1 and Figure 2The present disclosure provides a sterilization and deodorization device for an electric water heater, which is used in environments such as bathrooms (or toilets). The sterilization and deodorization device includes a shell, a light tube and an air circulation unit, wherein the shell has a accommodating space, the shell has an air inlet and an air outlet, the light tube is arranged in the accommodating space, the light tube is used to generate ozone, the air circulation unit is arranged in the accommodating space, and the air circulation unit is used to accelerate the flow of air inside the shell so that the air containing ozone in the shell flows out.

[0031] In the disclosed embodiment, the light tube is arranged at the air outlet, and the air circulation unit is located above the light tube; in this implementation, a fan is used to blow the ozone out of the device, and its implementation form is not limited to the blowing form, but includes the suction form. When blowing, the light tube is located in the downwind direction; when suction, the light tube is located in the upwind direction.

[0032] The air circulation unit comprises a fan. Preferably, the air circulation unit is a silent fan.

[0033] The wavelength of the light tube includes 185 nanometers. Specifically, a light tube with a wavelength of 185 nanometers is installed at the air inlet of the housing 5, and a light tube with a wavelength of 285 nanometers can be added to be installed at the air outlet, or other photocatalyst materials can be added to the housing space.

[0034] Furthermore, the air inlet is in a trumpet-shaped structure to reduce noise generated by the device.

[0035] Furthermore, the ozone generating area inside the shell corresponding to the light tube 4 is covered with a metal layer, and the metal layer is implemented by copper foil or electroplating.

[0036] Preferably, the light tubes are staggered with the air inlets and outlets so that the light tubes will not directly irradiate the outside of the housing.

[0037] Please refer to Figure 1 and Figure 2 In the sterilization and deodorization device disclosed in the present invention, the shell includes a cover plate 1 and an outer shell 5. The cover plate 1 is designed in accordance with the internal structure of the electric heater, and the outer shell 5 is also designed in accordance with the internal structure of the insulating plastic shell of the electric water heater to ensure the reliability of installation. The fan 3 is fixed inside the outer shell 5, and the light tube 4 is fixed inside the outer shell 5, located in the downwind position of the fan 3. The drive circuit 6 is located inside the outer shell 5, but cannot affect the installation of the light tube 4. The outer shell 5 is designed with an air outlet 501, the shape of which is not restricted. The ozone generated by the light tube 4 is evenly blown out from the air outlet 501 under the action of the fan 3. Figure 4 shown.

[0038] The cover plate 1 and the housing 5 are designed with snap-fit ​​assembly, but are not limited to the snap-fit ​​structure, and it is necessary to ensure that the assembly is reliable, firm and effective.

[0039] One end of the housing 5 is designed with an air inlet 502 of a special shape to reduce the spread of noise without affecting the air intake. Figure 3 The designs are shown but not limited to the following.

[0040] The passage inside the housing 5 is designed according to the air flow characteristics to minimize the impact of the internal structure on the air flow.

[0041] Since chemical reagents or large ozone generators are used, special operations are required, and continuous and effective sterilization and deodorization cannot be achieved. If the ozone concentration cannot be well controlled, it may even cause harm to the human body. However, the utility model is perfectly integrated with electric water heaters, and users can control the operation and suspension of the device at any time according to their specific needs, without having to consider the problem of ozone concentration control.

[0042] Specifically, Figure 4 As shown, the fan 3, the light tube 4, and the driving circuit 6 are fixed in the housing 5, respectively, and the fan 3 blows out the ozone generated by the light tube 4. Pasting corresponding noise reduction materials inside the housing 5 and the inner side of the cover 1 can reduce noise generation; pasting reflective materials in the area of ​​the light tube 4 can expand the irradiation range of the light tube, thereby enhancing the ozone generation efficiency. At the same time, the number of light tubes 4 can be increased in the housing 5, and the performance of the light tube module can be designed according to specific requirements, thereby realizing more other functions.

[0043] The fan 3 and the drive circuit 6 are both inside the housing and are sealed with glue to form the fan sealant 2 and the drive board sealant 7.

[0044] Preferably, the device uses a light tube module 4 with a wavelength of 185 nanometers, a silent fan 3, and no excess material is pasted on the inside and outside of the shell 5. The ozone requirement of the device is achieved by changing the power of the light tube.

[0045] The installation position of the device in this embodiment is determined by reference to the specific situation of the electric water heater, and is not limited to the position shown in the embodiment. The internal modules are designed with reference to the position of the actual effect, and are not limited to the position shown in the embodiment.

[0046] Please refer to Figure 2 In the present disclosure, when the user operates the control board 10 on the insulating shell 9 of the electric water heater 11, the drive circuit 6 is controlled through the communication harness 8. The drive circuit 6 forms a control signal through the calculation conversion of the internal circuit, drives the fan 3 and the light tube module 4 to work and generate ozone, thereby achieving the effect of deodorization and sterilization.

[0047] Although embodiments of the present disclosure have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present disclosure, and that the scope of the present disclosure is defined by the appended claims and their equivalents.
