Description

TECHNICAL FIELD The present invention relates to an air cleaner, and particularly to a built-in air cleaner.

BACKGROUND OF THE INVENTION With the rapid development of industry, science and technology, the situation of smoke and air pollution has become severe in recent years, and airborne particulates have a great impact on human health. Therefore, air purifiers have become one of the essential items in many places. The main working principle of conventional air purifiers is that a motor drives a fan to suck outside air into the main body, and the air sucked into the main body passes through various layers such as a pre-filter, high-performance filter, and activated carbon filter. The air was filtered sequentially to purify the air. Air purifiers are divided into floor-standing types and ceiling-embedded types depending on the installation location. Floor-standing air purifiers have the advantage of being easy to install, but they are large, the filter intake port is easily obstructed by surrounding items, the HEPA filter is a consumable item, and the motor does not require air intake. However, there is a drawback in that the stacked filters tend to generate noise. As shown in FIG. 1, a conventional ceiling-embedded air cleaner is installed on a lightweight steel frame 100 of a ceiling plate, and includes an intake device 1 and an exhaust device 2. The intake device 1 is composed of a coarse dust air filter and an intake motor. The exhaust device 2 is composed of a fan and a filtration device. The intake device 1 and the exhaust device 2 are connected through an air guide pipe 3, which performs circulation filtration to clean the air. Further, conventional ceiling-embedded air cleaners have the advantage of not taking up much space, but have the disadvantage of being expensive to install. Furthermore, since it was necessary to provide a sealed air guide pipe 3 between the intake device 1 and the exhaust device 2, the construction and equipment costs were high. Whether the air purifier is floor-standing or ceiling-mounted, the filter must be removed and cleaned or replaced frequently to maintain optimal filtration performance and reduce power consumption. However, it was very troublesome, took a lot of effort and time, and was not easy to use.

Therefore, there was room for improvement in conventional air purifiers, such as the above-mentioned problems, so after years of research and experience in the related technical field, the inventor finally developed the inset air purifier according to the present invention. This is the completed version.

The purpose of this invention is to provide a built-in air purifier that does not take up indoor floor space, is easy to construct, can effectively remove dust and sterilization, and can also purify indoor air. There is a particular thing.

In order to better understand the structural features of the present invention, the technical means used, and the effects expected to be achieved, the working principle of the present invention will be explained below. I believe it to be true.

See Figure 6. FIG. 6 is a circuit block diagram showing a built-in air cleaner according to an embodiment of the present invention. As shown in FIG. 6, when the power is turned on and the present invention is operated, the internal circulation will flow through the air intake holes 22 formed in the air guide plate 20 and the air passage formed in the main body 10. The fan 30 sucks indoor air into the main body 10, introduces it to the high-pressure discharge needle plate 60 through the air path, and finally releases it through the exhaust hole 23 of the air guide plate 20, 60 generates a fixed frequency switch signal using an MCU (Micro Control Unit), adjusts the magnitude of the output high voltage using the PWM (Pulse Width Modulation) method, and converts 5V DC into high voltage AC using the MOS tube under the isolation transformer. After the conversion, ions such as high-pressure plasma are generated at the needle tip on the high-pressure discharge needle plate 60 using a multi-stage voltage doubling method, and the high-pressure discharge needle plate 60 provides a discharge path to generate high-concentration nanoscale negative ions. The high concentration of negative oxygen ions generated by high-pressure plasma and other ions are nanoscale, so they can completely cover dust very easily, starting from PM1.0 and reacting, causing dust to snowball. The dust gradually increases in size and eventually falls to the ground, and the dust reaction is in the order of PM1.0 → PM2.5 → PM10. In addition, because negative oxygen ions are negatively charged, the surface of bacteria is generally positively charged, causing a charge interaction between negative oxygen ions and bacteria to be attached to the surface of bacteria. . It can interfere with the structure and function of bacteria and inhibit their growth and reproduction. Therefore, the circulation fan 30 continuously circulates indoor air through the air passage formed in the main body 10 and the high-pressure discharge needle plate 60, and removes high-concentration nanoscale negative air generated by ions such as high-pressure plasma. Oxygen ions cover indoor dust and bacteria and destroy their cell walls. Highly concentrated negative oxygen ions generated by ions such as high-pressure ions cover dust PM2.5 and bacteria in the indoor air, destroy and remove them, and finally fall to the floor. Thereby, it is possible to remove dust and bacteria, and purify the indoor air.

Furthermore, as a result of testing this invention by the "China Guangdong Provincial Microbial Testing Center", its dust removal rate and antibacterial rate were over 99%.

As can be seen from the above, the features of the self-contained air purifier of the present invention and the expected effects that can be achieved include the following (1) to (7).
(1) Easy to install.
(2) Cost is low because intake and exhaust are performed in the same device.
(3) Adopts an electronic filter method, which sterilizes and removes dust using ions such as plasma, eliminating the need for consumables.
(4) Since the dimensions of the device are the same as those of the LED recessed light, it can be replaced with an LED recessed light at any time, and there is no need to drill holes again.
(5) Low cost.
(6) Does not take up floor space.
(7) An appropriate number can be installed depending on the size of the area, and there are no restrictions due to space.

To summarize the above, this invention has a high degree of inventiveness and practicality among products of the same type, and even when we searched domestic and foreign technical documents, we did not find a similar structure in the literature, and it is difficult to register as a utility model. In order to meet the requirements, we hereby apply for utility model registration in accordance with the law.
