Description

Window type air cleaner {Window type air cleaner}

The present invention relates to a window-type air purifier that can be installed on a window frame and purify indoor air. It has the advantage of being able to be installed without processing the existing window frame or window, and prevents cross-contamination between purified air and polluted air. This relates to a window-type air purifier that can improve air purification efficiency.

In general, as interest in indoor air quality (IAQ) within buildings increases, the demand for air purification devices to remove various pollutants contained in air supplied indoors from outside is increasing.

Typically, air purification devices simply use filters made of porous material or electrostatic dust collection filters. Conventional air purification devices that use such porous material filters or electrostatic dust collection filters have the problem of not being able to efficiently remove polluted air containing carbon dioxide (CO2) downstream indoors, which is heavier than air.

In other words, since ordinary air purifying devices are installed only in indoor spaces, they can only perform the function of filtering out indoor polluted air. Therefore, when used for a long time with the windows closed, the indoor carbon dioxide concentration increases, which can harm people living indoors. It can cause discomfort, deterioration of health, and problems with the body's autonomic nervous system, and for this reason, it can cause various diseases.

Due to this problem, there was the inconvenience of having to ventilate frequently, and frequent ventilation caused energy loss due to the temperature difference between outside air and indoor air, which lowered cooling and heating efficiency. In addition, when installing an air purifier on an existing window or window frame, limitations such as the need to perform additional processes such as processing the existing window and window frame or installing additional brackets, etc. were encountered.

Therefore, there is a need to develop an air purifier that can be installed on a conventionally installed window frame, can provide ventilation by exchanging indoor polluted air with outdoor air, and does not reduce cooling and heating efficiency.

After the housing 200 is processed to the length to be installed, housing caps 500, which are means for sealing the receiving space S of the housing 200, may be formed on the upper and lower sides of the housing 200, respectively. The configuration of the housing cap 500 can prevent foreign substances from entering the housing 200.

The housing 200 can be coupled to the rail of the window frame 10 and slid together with the fixed window 100. Accordingly, the housing 200 has a structure in which one side and the other side can be exposed to the outside and the indoor space, respectively, and external air and indoor air enter and exit through the exposed one side and the other side. A detailed description of the external air and indoor air flowing into the housing 200 will be provided below.

The air cleaning module 300 may be inserted into the upper or lower side of the open housing 200 and fixed to the receiving space (S) of the housing 200.

It may include first and second suction fans 330 and 340 that provide suction force for sucking air and external air, respectively.

The indoor air sucked from the indoor space passes through the total heat exchanger 310 and is then discharged to the outside through the first suction fan 330 (see (a) in Figure 3), and the external air drawn in from the outside is discharged to the outside through the total heat exchanger (310). After sequentially passing through 310) and the filter unit 320, it can be discharged into the indoor space. (See (b) in Figure 3)

In addition, the interior of the air cleaning module 300 is preferably divided into passages through which indoor air and outdoor air move, so that they do not cross or mix with each other.

Referring to Figures 1 to 4, an outdoor air inlet 210 through which external air flows is formed on one side of the housing 200, and the indoor air passing through the air cleaning module 300 is spaced a predetermined distance from the outdoor air inlet 210. An internal outlet 220 is formed through which air is discharged to the outside. Preferably, the outside air inlet 210 is formed on the lower side of the housing 200, and the internal air outlet 220 is formed on the upper side of the housing 200.
