Description

[Detailed explanation of the idea]

(Field of Industrial Application) The present invention relates to an air cleaner that maintains high performance of the deodorizing filter by controlling the humidity of the air passing through the deodorizing filter at a constant level. (Prior Art) Conventional air cleaners include those shown in FIGS. 4 and 5, for example. That is, in the system shown in FIG. 4, air sucked into a duct 102 by a blower 101 is guided into water W in a water tank 103, and the malodorous components contained in the air are directly dissolved in the water W, thereby removing the malodorous components. The clean air is discharged from the duct 104 to the outside of the machine. In addition, in Figure 4, 1
05 is a dust filter. Also, what is shown in FIG. 5 is a dust filter 106 and a blower 107.
A deodorizing filter 108 is disposed between the deodorizing filter 108 and the deodorizing filter 108 is wetted with water W flowing out from the tap 109 to eliminate ammonia and hydrogen sulfide contained in the air passing through the deodorizing filter 108. This removes malodorous components by dissolving them in the water contained in the deodorizing filter 108. In FIG. 5, reference numeral 110 is a tray for water falling from the deodorizing filter 108. (Problems to be solved by the invention) However, the air purifier shown in FIG. In the case of the air purifier shown in the figure, a water supply is required, and the ejected air tends to be too humid or unstable, making it impossible to maintain the performance of the deodorizing filter 108 at a high level at all times. There was a problem that. The present invention was developed in view of the above problems, and its purpose is to improve the performance of the deodorizing filter by keeping the humidity of the air passing through the deodorizing filter constant and supplying a constant amount of moisture. We are here to provide you with a small air purifier that can be kept high at all times. (Means for Solving the Problems) In order to achieve the above object, the present invention includes a main body through which air passes from below to above, a cooling device disposed inside the main body, and a cooling device connected to the cooling device. a deodorizing filter placed below the cooler to deodorize the air by receiving water in the air that has condensed on the cooler; and a deodorizing filter placed above the cooling device to deodorize the air. and a radiator that increases the temperature of the cooled air. (Function) According to the air cleaner of the present invention, air is introduced from below the main body. Air introduced from below the main body is deodorized by passing through a deodorizing filter. The deodorizing filter is, for example, Fe()-
Phthalocyanine is supported on rayon or porous resin, and the supply of moisture accelerates the catalytic reaction against malodorous substances, increasing its sustainability. Cooling is preferably performed by an electronic cooling device using a semiconductor. When the air deodorized by the deodorizing filter is cooled to the dew point by the cooler placed above the deodorizing filter, the moisture in the air condenses on the cooler, and the condensed moisture flows to the deodorizing filter below. to fall. Therefore, a constant amount of moisture is always supplied to the deodorizing filter, and the function of the deodorizing filter is maintained. Incidentally, the air that has passed through the cooler is heated to room temperature by a radiator placed above the cooler, and then discharged to the outside of the main body. (Example) An example of the present invention will be described below based on the accompanying drawings. FIG. 1 is a schematic vertical sectional view of an air cleaner according to the present invention. In the air cleaner 1 shown in FIG. 1, 2 is the main body of the air cleaner. The main body 2 of the air cleaner is provided with an air inlet 3 at the bottom and has an exhaust port 4 at the top for discharging air. Furthermore, a fan 5 is provided inside the main body 2 of the air cleaner to guide air introduced from the air inlet 3 to the outlet 4. A power transformer 6 is provided below the fan 5. In addition, an electronic cooling device 7 is provided below the power transformer 6.
is arranged, and a cooling fin 8 as a cooler is connected to one side of the cooling device 7. Further, a heat sink 9 is connected to the other side of the electronic cooling device 7. The heat sink 9 extends upward, and a heat sink fin 10 as a heat sink is provided above. Further, below the cooling fins 8, a deodorizing filter 11 is installed inside the air purifier main body 2. The deodorizing filter 11 is one in which Fe()-phthalocyanine is supported on rayon or a porous resin such as polyvinyl butyral. Further, the electronic cooling device 7 has a configuration as shown in FIG. In the figure, 12, 13, 14, 1
5 are P-type and N-type semiconductors, respectively, and these semiconductors 12, 13, 14, and 15 are metal pieces 1 such as copper.
6 and 17. These P type or N
When a direct current is passed from a power source 18 through the semiconductor bonded body of the mold, the upper metal piece 16 is cooled and removes heat from the surroundings. This is because the electron has a low energy level P
This is because energy is taken away in the form of heat when transferred from the N-type semiconductors 12 and 14 to the N-type semiconductors 13 and 15, which have a high energy level, via the metal piece 16. The electrons that have absorbed thermal energy flow through the N-type semiconductors 13 and 15, and when they pass through the lower metal piece 17 to the P-type semiconductors 12 and 14, they become heat again and are emitted to the outside. If we dissipate the heat on the high temperature side efficiently,
Heat is continuously pumped from the cold side to the hot side. In this embodiment, an element with a side of 30 mm is preferably used as the electronic cooling device 7, and this element has the following characteristics:
It operates with a voltage and current of 5V, 1A. The air cleaner 1 configured as described above operates as follows. As the fan 5 rotates, air is introduced from the air inlet 3 provided below the main body 2 of the air purifier. The air introduced from the air inlet 3 is deodorized when it passes through the deodorizing filter 11.
As described above, the deodorizing filter 11 is made of Fe()-phthalocyanine supported on rayon or porous resin, and the supply of moisture accelerates the catalytic reaction against the malodorous substance, increasing its sustainability. On the other hand, the air deodorized by the deodorizing filter 11 is cooled to below the dew point temperature by the cooling fins 8 disposed above the deodorizing filter 11. Cooling is done by electronic cooling device 7 using N-type and P-type semiconductors.
It is carried out by. When the cooler is cooled to the dew point, moisture in the air condenses on the cooling fins 8, and the condensed moisture falls onto the deodorizing filter 11 below, thereby constantly supplying a constant amount of moisture to the deodorizing filter 11. be done. Incidentally, the air that has passed through the cooling fins 8 is heated to room temperature by the heat radiation fins 10 disposed above the cooling fins 8, and is discharged to the outside of the air cleaner body 2. The deodorizing effect of the fibrous deodorizing filter 11, which has Fe()-phthalocyanine supported on rayon, against the four major malodorous substances was compared with respect to the presence or absence of moisture. The data of odor concentrations measured at the side and outlet side using gas detection tubes are shown in Tables 1 and 2 below. As for ammonia, it has been shown that it has a deodorizing effect just by the presence of water.
