Description

Technical Field

[0001] The utility model belongs to the technical field of air duct machine sterilization, in particular to an air duct machine sterilization and purification device and an air duct type air conditioner. Background Art

[0002] In recent years, with the development of the economy, people's living standards have continued to improve, and more and more families have paid more attention to indoor air quality. Ducted air conditioners have become very popular products in home decoration. However, when the ducted air conditioner is used for a long time, bacteria and other substances that are not conducive to the user's health that enter with the wind will continue to accumulate inside the ducted air conditioner. When the ducted air conditioner is started, these harmful substances will be blown into the room along the air duct, thereby causing a certain impact on the user's health.

[0003] Although existing fresh air systems are equipped with filtration devices that can filter out bacteria and dust particles such as PM2.5 in the air, after a period of use, bacteria will seriously adhere to the filter screen, and the filter screen needs to be disassembled and cleaned to ensure normal filtration. However, this operation not only increases the workload of workers, but also changes the filter screen composition, which reduces the filtration effect of the filter screen. Therefore, it is important to avoid frequent cleaning or replacement of the filter screen.

[0004] Secondly, in the existing technology, the cleaning and sterilization of the inside of the duct unit in the fresh air system is mostly done manually by regularly using air conditioning cleaning agents to manually clean the inside of the duct unit. This not only increases the workload of workers and is time-consuming and labor-intensive, but also makes it difficult to ensure the cleaning effect. It is also not friendly to users with inconvenient hands and feet, does not consider the source of harmful substances such as bacteria, and does not fundamentally solve the problem, making the duct unit prone to breeding bacteria. Utility Model Content

[0005] The purpose of the utility model is to provide a duct air conditioner sterilization and purification device and a duct air conditioner, which, on the one hand, solves the technical defects of manual cleaning of the filter, which increases the workload and causes the filtering effect of the filter to decrease; on the other hand, it solves the technical defects of manual cleaning of the inside of the duct air conditioner using air conditioning cleaning agents on a regular basis, which makes it difficult to ensure the cleaning effect and is not friendly to users with inconvenient hands and feet.

[0006] In order to achieve the purpose of the present invention, the present invention is implemented through the following technical solutions:

[0040] In recent years, with the development of the economy, people's living standards have continued to improve, and more and more families have paid more attention to indoor air quality. Ducted air conditioners have become very popular products in home decoration. However, when the ducted air conditioner is used for a long time, bacteria and other substances that are not conducive to the user's health that enter with the wind will continue to accumulate inside the ducted air conditioner. When the ducted air conditioner is started, these harmful substances will be blown into the room along the air duct, thereby causing a certain impact on the user's health.

[0041] Although existing fresh air systems are equipped with filtration devices that can filter out bacteria and dust particles such as PM2.5 in the air, after a period of use, bacteria will seriously adhere to the filter screen, and the filter screen needs to be disassembled and cleaned to ensure normal filtration. However, this operation not only increases the workload of workers, but also changes the filter screen composition, which reduces the filtration effect of the filter screen. Therefore, it is important to avoid frequent cleaning or replacement of the filter screen.

[0042] Secondly, in the existing technology, the cleaning and sterilization of the inside of the duct unit in the fresh air system is mostly done manually by regularly using air conditioning cleaning agents to manually clean the inside of the duct unit. This not only increases the workload of workers and is time-consuming and labor-intensive, but also makes it difficult to ensure the cleaning effect. It is also not friendly to users with inconvenient hands and feet, does not consider the source of harmful substances such as bacteria, and does not fundamentally solve the problem, making the duct unit prone to breeding bacteria.

[0043] In order to solve the above-mentioned defects in the prior art, the inventor provides a duct air conditioner sterilization and purification device and a duct air conditioner.

[0044] like Figure 1 、 Figure 2 and Figure 3 As shown, in the first aspect of this embodiment, a sterilization and purification device for a ducted air conditioner is provided, comprising: a filter frame, which is a rectangular structure with a circular opening in the middle, a filter assembly, and the filter assembly is divided into three layers, the first layer is a nylon material filter screen, the second layer is a composite dust collection filter screen, and the third layer is a photocatalyst material filter screen. The return air duct 3 is arranged at one end of the filter frame, and a filter assembly is provided in the return air duct 3, and the filter assembly is divided into three layers, the first layer is a nylon material filter screen, the second layer is a composite dust collection filter screen, and the third layer is a photocatalyst material filter screen, wherein the first layer, the second layer and the third layer of filter screens are all installed on the inner wall of the return air duct 3 through a snap-fit structure 4, as shown in FIG. Figure 4-Figure 6As shown, when disassembling, it is only necessary to press down the snap structure 4 to loosen the connection between the inner wall of the return air duct 3 and the filter, and then pull the filter out of the return air duct 3, so that the filter can be quickly and conveniently disassembled and replaced. The sterilization and purification component is arranged in a ring on the inner wall of the return air duct 3. The sterilization and purification component is used to emit ultraviolet light with a wavelength of 200 to 300nm to the inner wall of the return air duct 3. The sterilization and purification component is installed inside the return air duct 3 of the duct machine. During use, the sterilization and purification component can disinfect and purify the bacteria on the filter component in real time by emitting ultraviolet light to the inside of the return air duct 3. There is no need to manually disassemble and purify the filter component, which reduces labor and ensures the reliability and sustainability of the filtering performance of the filter component. Secondly, the ultraviolet light also indirectly sterilizes and purifies the inner wall of the return air duct.

[0045] Finally, the sterilization and purification component eliminates the need for additional internal space within the ducted unit and can fully disinfect incoming air, preventing bacteria from accumulating within the unit. This ensures clean airflow throughout the unit and protects the user's health. Furthermore, the filter component absorbs dust from the air, preventing it from adhering to the sterilization and purification component, thereby increasing its efficiency and lifespan.

[0046] Secondly, since the sterilization and purification component is arranged in a ring on the inner wall of the return air duct 3, it can be operated more conveniently through the duct opening during maintenance or replacement without large-scale disassembly of the entire system, which reduces maintenance costs and difficulty and improves the reliability and service life of the equipment.

[0047] Finally, through continuous and efficient sterilization and purification, the device can significantly reduce the content of harmful microorganisms such as bacteria and viruses in the return air duct and indoor air, thereby improving indoor air quality, which is of great significance for preventing respiratory diseases and protecting human health.

[0048] like Figure 1 and Figure 2 As shown, the sterilization and purification component includes a bracket 1 and a sterilization module 2. The bracket 1 is a long strip structure and is provided in plurality. The plurality of brackets 1 are arranged in sequence on the inner wall of the return air duct 3 at intervals. A mounting hole is provided on the bracket 1, and the sterilization module 2 is arranged in the mounting hole. In addition, a plurality of mounting holes are arranged in sequence at intervals along the length of the bracket 1, and a sterilization module 2 is provided in each of the plurality of mounting holes.

[0049] The sterilization module 2 is preferably a UVC-LED. UVC-LED can emit ultraviolet light with a wavelength of 200-280 nanometers. Ultraviolet light in this wavelength band has a strong destructive power against microorganisms such as bacteria and viruses, and can directly destroy their DNA or RNA structures, thereby achieving a sterilization effect.

[0050] At the same time, UVC-LED has the characteristic of fast startup, which can reach the ultraviolet intensity required for sterilization in a short time, thereby quickly killing microorganisms in the air and reducing the survival time of viruses and bacteria in the air.

[0051] In this embodiment, the sterilization module 2 is connected to the duct air conditioner power supply via a voltage-varying circuit. The voltage-varying circuit can automatically adjust the sterilization module's operating voltage based on the duct air conditioner's operating status and actual needs. This intelligent control ensures that the sterilization module operates in optimal conditions, improving sterilization efficiency. Secondly, through precise voltage regulation, the sterilization module can be prevented from overworking when not needed, thereby reducing unnecessary energy consumption and achieving energy conservation and power saving. During use, the sterilization modules 2 are installed on the bracket 1 at equal intervals along the length direction and emit ultraviolet light through the mounting holes to fully disinfect and sterilize the incoming air in the entire return air duct 3. The bracket 1 can be made of plastic or glass. One end of the bracket is installed at the connection between the return air duct 3 and the indoor unit, and the other end is installed at the connection between the return air outlet and the duct. To ensure sterilization without blind spots, the edges of the irradiation areas of adjacent sterilization modules 2 will partially overlap. When the duct air conditioner is turned on, the sterilization and purification component will be electrically connected to the internal power supply and automatically begin operation, disinfecting the irradiated area with the ultraviolet light emitted by the sterilization module 2. Since the sterilization and purification device is directly installed in the return air duct 3, there is no need to occupy additional space inside the duct machine; when the duct machine is turned on, the incoming air first passes through the filter component to filter dust, which can prevent dust from adhering to the sterilization and purification component. The sterilization and disinfection module performs ultraviolet disinfection on bacteria and other substances in the incoming air of the return air duct 3 to avoid the accumulation of harmful substances inside the duct machine, so that the entire duct machine can achieve clean air outlet and protect the health of users.

[0052] In a second aspect, this embodiment provides a ducted air conditioner, comprising an air conditioner body, wherein the sterilization and purification device as described above is installed between the return air inlet and the fan of the air conditioner body.

[0053] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
