Description

Air conditioning disinfection and sterilization device

The present invention relates to a disinfection device, in particular a device installed in an air conditioner to disinfect and sterilize the air.

Air conditioners are the most commonly used temperature control devices. They regulate the air temperature by sucking in air from the outside into the air conditioner and cooling or heating it through the internal heat exchange fins. Considering that air conditioners are more energy-efficient during use, air conditioners usually suck in indoor air and discharge it indoors after cooling or heating. Therefore, the air in indoor spaces where air conditioners are usually used rarely convects with outdoor air. For crowded spaces, if there are bacteria or viruses, these bacteria or viruses may be spread to the entire space through the convection of the air conditioner. Although some air conditioners are equipped with filters or silver ion filtration and disinfection and sterilization devices, these devices have a certain service life or capacity, so they need to be replaced regularly. If their service life is exceeded, they will become ineffective. And it is very troublesome to replace or clean these devices.

In view of the above shortcomings of the existing technology, the present invention provides an air conditioner disinfection and sterilization cover device, which can be directly installed at the air inlet of the existing air conditioner to achieve the disinfection and sterilization function without affecting the normal operation of the air conditioner. The installation is also very simple.

The present invention is realized by the following technical scheme: An air conditioner disinfection and sterilization device is detachably installed at the air inlet of the air conditioner and covers the air inlet, and includes a shell, a disinfection and sterilization device is arranged at the center of the shell, air inlets are uniformly distributed along the radial direction on the side wall of the shell, and an air outlet is also arranged at the center of the shell, and the air outlet corresponds to the air inlet of the air conditioner; the air inlet of the air conditioner forms a negative pressure, so that the air outside the air inlet enters the shell and flows through the disinfection and sterilization device to complete the disinfection and sterilization, and then enters the air inlet of the air conditioner from the air outlet.

Preferably, the air inlet is a vortex air duct extending along the side wall of the shell toward the center of the shell, and the air forms an air vortex at the center of the shell where the disinfection and sterilization device is located after passing through the vortex air duct.

Preferably, the disinfection and sterilization device is an ultraviolet lamp.

Preferably, the ultraviolet lamp is an ultraviolet LED.

Preferably, a light-transmitting window is provided in the center of the housing for displaying the working status of the ultraviolet lamp.

Preferably, the distance between the UV LED and the bottom surface of the porous plate is 5-100 mm.

Preferably, the air outlet of the housing is covered with a porous plate.

Preferably, the surface of the porous plate is coated with a photocatalytic coating for disinfection and sterilization.

Compared with the existing technology, the beneficial effect of this new type is that the device can be conveniently fixed at the air inlet of the air conditioner through a bracket, and the external air is sucked into the shell under the negative pressure generated by the air inlet of the air conditioner, and then the disinfection and sterilization device in the shell kills the bacteria or viruses in the air before entering the air conditioner through the air inlet for cooling or heating, thereby effectively preventing the possibility of bacteria or viruses spreading through the air conditioner.

In order to more clearly illustrate the technical solution in this novel embodiment, the technology in the embodiment is described in detail below in conjunction with the attached figures.

Figure 1 is a three-dimensional diagram of the new model; Figure 2 is a disassembled diagram of the new model.

Referring to Figures 1 and 2, an air conditioner disinfection and sterilization device is detachably mounted at the air inlet of the air conditioner and covers the air inlet. The device comprises a housing (1), a disinfection and sterilization device (2) is arranged at the center of the housing (1), air inlets (3) are uniformly distributed along the radial direction of the side wall of the housing (1), and an air outlet (6) is also arranged at the center of the housing (1), and the air outlet (6) corresponds to the air inlet of the air conditioner. The device can be conveniently fixed at the air inlet of the air conditioner through a bracket. Under the negative pressure generated by the air inlet of the air conditioner, the external air is sucked into the housing (1) through the air inlet (3). The disinfection and sterilization device (2) in the housing (1) then kills the bacteria or viruses in the air before the air is discharged from the air outlet (6) through the air inlet into the air conditioner for cooling or heating, thereby effectively preventing the possibility of bacteria or viruses spreading through the air conditioner.

Since the overall design of the device is relatively thin, but considering that the disinfection and sterilization device (2) needs a certain amount of time to complete the disinfection and sterilization, it is necessary to extend the retention time of the air in the housing (1), and at the same time enable the disinfection and sterilization device (2) to have a more sufficient disinfection and sterilization effect on the inhaled air, the air inlet (3) is designed as a vortex air duct extending along the side wall of the housing (1) toward the center of the housing (1). After the air passes through the vortex air duct, an air vortex is formed at the center of the housing (1) where the disinfection and sterilization device (2) is located. The air vortex will flow around the disinfection and sterilization device (2), so that the air can be fully contacted by the disinfection and sterilization device (2) and complete the disinfection and sterilization process. At the same time, the air vortex generated can also increase the air retention time in the housing (1) to meet the requirements of disinfection and sterilization.

The above-mentioned disinfection and sterilization device (2) can be implemented in many ways, such as ozone generator, silver ion, etc., but these methods are not very suitable for air conditioning devices. For example, ozone will produce unpleasant odors and irritate the respiratory system. Silver ions have a certain service life and need to be replaced regularly, so they are not used much. The new type preferably uses ultraviolet lamps as disinfection and sterilization devices. Ultraviolet lamps with appropriate wavelengths can be selected to achieve the effect of disinfection and sterilization while avoiding or reducing the generation of ozone. Moreover, the ultraviolet rays generated by the ultraviolet lamp can fully cover the entire space in the housing (1), making the disinfection efficiency more efficient and more energy-saving. In order to further save energy and reduce the size of the device, the UV lamp uses UV LED. Since LED has lower power, only 10mW is needed to meet the needs of disinfection and sterilization. Different models of UV LEDs also have corresponding effects on the distance of disinfection and sterilization, especially for UV LEDs of different wavelengths. The creator tested that the distance between the UV LED and the bottom of the porous plate is 5-100mm to achieve the most ideal effect. At the same time, the overall size of the device can be further reduced.

In order to facilitate the user to understand the working status of the device, a light-transmitting window (5) for displaying the working status of the ultraviolet lamp is provided in the center of the housing (1). A small amount of ultraviolet light passes through the light-transmitting window (5), so that the user can easily understand whether the device is in working status by observing the light-transmitting window (5).

In addition, a porous plate (4) is provided at the air outlet (6) of the housing (1), and the porous plate (4) can maintain the air vortex formed in the housing (1) to increase the retention time of the air in the housing (1). A photocatalytic coating layer for disinfection and sterilization can also be coated on the surface of the porous plate (4), and the photocatalytic coating layer produces a strong disinfection and sterilization effect under the irradiation of an ultraviolet lamp, so that the air passing through the porous plate (4) is further disinfected and sterilized.
