Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner arranged indoors, and more particularly to an air conditioner which blows out temperature-controlled air passing through a heat exchanger from a blow-out frame through a wind direction plate. .

[0002]

2. Description of the Related Art Generally, an air conditioner (indoor unit) arranged indoors is constructed to blow out air whose temperature has passed through a heat exchanger and whose temperature has been adjusted through a wind direction plate from a blowing frame. During the heating operation, in recent years, the feeling of heating is increased by increasing the temperature of the hot air blown out or by causing the hot air to convection in the room.

Further, during cooling operation of the air conditioner, dew condensation is likely to occur on the blowing frame, wind direction plate, etc. constituting the outlet, and such dew condensation is prevented from falling to the floor.
Japanese Patent Publication No. 9-14667 proposes a technique of planting hair on the wind direction plate.

[0004]

However, in the above-described method for enhancing the feeling of heating, since hot air is blown directly to human skin or high-temperature air is blown directly,
There is a problem that it is too direct to obtain a sufficiently pleasant heating feeling.

Further, the technique of planting hair on the wind direction plate to prevent dew condensation has a problem that although the dew condensation can be prevented from falling, the flocked portion is easily soiled, which causes mold.

[0006] Therefore, the present invention is to provide an air conditioner capable of providing a pleasant heating feeling, preventing the generation of mold and preventing the dew condensation from falling on the floor.

[0007]

In order to solve the above-mentioned problems, the present invention provides a heat exchanger, a blow-out frame for blowing out temperature-controlled air passing through the heat exchanger, and an attachment to the blow-out frame. In the air conditioner provided with the wind direction plate that changes the direction in which the air is blown, the blowout frame and / or the wind direction plate is made of ceramic or a member having ceramics.

[0008]

In the air conditioner of the present invention, since the blow-out frame and / or the wind direction plate constituting the blow-out port is made of a ceramic member, the far-infrared rays emitted by the far-infrared ray radiating action of the human are human skin. Inner hot spot (the part where you feel the temperature)
Since it is absorbed in the vicinity of, the temperature of the skin near the hot spot rises, and a so-called radiant heating can provide a pleasant mild heating feeling.

Further, during cooling operation, the water molecules that are excited vibrationally by the radiant energy of far infrared rays emitted from the ceramic member have more energy than ordinary water, so the temperature becomes higher than that of ordinary water and dew condensation occurs. Less likely to occur.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to FIGS. 1 and 2 of the accompanying drawings.

As shown in FIG. 1, an air conditioner 1 according to an embodiment of the present invention is a separate type air conditioner, and is installed on an indoor wall by a metal installation plate 2. Installation plate 2
Has a hooking piece 3 formed on the upper part thereof.
A hook 5 provided on the back plate 4 of the air conditioner 1 is hooked from above. At the bottom of the installation plate 2, a fixing piece 6
The fixing piece 6 is formed with a fixing member 7 made of synthetic resin provided on the lower portion of the back plate 4 from above.

The air conditioner 1 is composed of a main body 9 and a suction panel 10 pivotally supported on the main body 9 by an arm 8 so that a curve is formed between the suction panel 10 and the main body 9. The pre-filter 11 is attached.
The pre-filter 11 removes relatively large dust and the like, and after removing the relatively large dust and the like through the pre-filter 11, the air filter 12 arranged in the main body 9 is removed.
It removes relatively fine dust and odor.

Inside the main body 9, a heat exchanger 13, a drain pan 14, a cross flow fan 15, vertical blades 16 (air flow direction plates), and horizontal blades (air flow direction plates) 17 are housed and formed on the suction panel 10. The air sucked from the suction port 20 and the suction port 21 is heat-exchanged in the main body 9, and then the air outlet 1
It is supposed to be blown out from 9. A refrigerant pipe 23 is stored in the storage portion 22 at the lower rear portion of the main body 9.

The blowout frame 19a constituting the blowout port 19 and the vertical blades 16 and the horizontal blades 17 as wind direction plates are respectively
A far-infrared radiating ceramic is included in a ceramic member (ceramics) whose main wavelength range of radiated far-infrared rays is 8 to 14 μm. It is made from a ceramic member with a different structure. As described above, by forming the member forming the blowout port 19 from the ceramic member, a pleasant mild heating feeling can be obtained, and dew condensation is less likely to occur and mold is less likely to occur.

At the lower end of the heat exchanger 13, the drain pan 1
4 is provided to receive the dew condensation of the heat exchanger 13.

As shown in FIG. 2, the drain pan 14 has an inner portion 14a for receiving a heat exchanger, which is made of a ceramic member, and an outer portion of which is covered with a heat insulating material 14b. By thus forming the inner portion of the drain pan 14 with the ceramic member, it is possible to prevent or suppress the generation of mold in the drain pan 14.

Next, the operation of this embodiment will be described.

In FIG. 6, when the cross flow fan 15 is driven, the air taken in through the suction port 20 and the suction port 21 passes through the pre-filter 11, the air filter 12, and the heat exchanger 5 to exchange heat. After being blown, it is blown out from the blowout port 19.

At the time of heating operation, far infrared rays emitted by the ceramics are absorbed at the air outlet 19 at a location near the inside of human skin (a portion where human feels temperature).
The temperature of the skin near the hot point rises, and a pleasant mild heating feeling can be obtained. Generally, the human warm point is said to be about 0.3 mm below the skin, and the wavelength of far infrared rays is usually 2 μm to 1 mm (or 4 μm to 1 mm).
mm) range, but wavelengths in this range are considered to be easily absorbed at sites near the warm point in the skin. Therefore, since it is heated from the inside of the skin, a soothing and mild feeling of heating can be obtained by so-called radiant heating.

Further, during the cooling operation, the water molecules that are vibrationally excited by the radiant energy of the far infrared rays emitted from the ceramic member in the air outlet 19 have more energy than ordinary water, and therefore have a higher temperature than ordinary water. become,
Condensation is less likely to occur. Further, due to the sterilizing effect of far infrared rays, mold is less likely to be generated at the air outlet 19.

As described above, the ceramic member has a bactericidal action because the far-infrared radiating ceramic makes a substance having a reducing property or an oxidizing property by contact with water, and these substances are biological substances such as bactericidal property. It is thought that this is due to exerting such a function.

That is, the far-infrared radiation ceramics acts on water to produce HO ₂ , and this HO ₂ causes a reaction of the following formula (1) to perform a reducing action to give e ⁻ .

[0023]

[Equation 1] In addition, the reaction of the following formula (2) is caused to perform an oxidizing action of depriving e ⁻ .

[0024]

[Equation 2] Further, even when a ceramic member is used for the drain pan 14, these reducing and oxidizing substances also have a sterilizing function, so that mold can be prevented from occurring in the drain pan.

That is, in the drain pan of the heat exchanger,
From the past, dust and various things adhere to the drain,
When iron bacteria and the like propagate and slamming (agar-like substance) occurs due to this, the drain hose connection port may be closed, causing water leakage. It has been considered to apply antibacterial treatment to the drain pan, but when dirt adheres to the antibacterial surface, mold is generated on the dirt.
However, such inconvenience is eliminated by using a ceramic member for the drain pan.

The present invention is not limited to the above embodiment,
Various modifications can be made without departing from the scope of the present invention.

For example, the blowing frame 19a and the wind direction plates 16 and 1
7 is not limited to be made of ceramics or a member having ceramics, and the same effect can be obtained even if at least one of the blowing frame 19a or the wind direction plates 16 and 17 is made of ceramics or a member having ceramics. be able to.

[0028]

According to the present invention, since the blowout frame and / or the wind direction plate of the air conditioner are made of ceramic or a member having ceramic, the far infrared radiation effect of the ceramic provides a comfortable and mild heating feeling. Can be obtained, and it becomes difficult for dew condensation to occur and for mold to occur.
