Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circulator for circulating indoor air, and more particularly to a circulator mounted on an indoor wall.

[0002]

A circulator is a blower for distributing the air heated by a heating device to the whole room without keeping it in one place. That is, while the air heated by the heating device easily stays in the upper part of the room, the air in the upper part of the room is blown downward. This type of conventional circulator has a simple structure in which a blower is simply attached to an indoor wall. For this reason, there is a problem in that dust and odorous components are circulated in the same manner by circulating indoor air.

[0003] In addition, various types of indoor deodorizers have been conventionally known, and this type of conventional deodorizer is generally of the type used by placing it on a floor in a room. for that reason,
There is a problem that the installation space is required on the floor, which takes up space.

An object of the present invention is to solve such a problem, and an object of the present invention is to provide a circulator capable of deodorizing. It is another object of the present invention to provide a circulator capable of collecting dust.

[0005]

In the circulator according to the first aspect of the present invention, the air in the room is sucked in from above the circulator body, discharged and circulated downward by driving the blowing means. The air inside the room is heated by using the heater, but the warm air is
Cold air splits down into the lower part of the room. On the other hand, by the action of the circulator, warm air in the upper part of the room is sent to the lower part of the room, and the air in the room convects, so that the temperature distribution in the room becomes constant. Further, when the air passes through the deodorizing device on the suction side or the discharge side of the blowing means, the air is deodorized.

Further, in the circulator according to the second aspect of the present invention, when air comes into contact with a discharge light excitation type photocatalyst device constituting a deodorizing device, ammonia, acetic acid, etc., which are malodorous components contained in the air, or sick house disease. Formaldehyde, which is the causative substance of the odor, is decomposed into harmless substances, and the odor is removed. At that time, ozone is generated from the photocatalyst device, and this ozone is decomposed by the catalyst and is not released indoors.

In the circulator according to the third aspect of the present invention, dust in the air is collected by a dust collecting device provided at a suction port of the circulator body. In addition, since the air from which dust has been removed in this way passes through the deodorizing device, clogging of the deodorizing device can be suppressed.

The suction port 3 is provided with a pre-filter 11 as a dust collecting device for collecting relatively large dust such as cotton dust in the air. Further, a deodorizing device 14 including a photocatalytic device 12 of a discharge light excitation type and an ozone decomposing catalyst 13 as a catalyst for decomposing ozone generated from the photocatalytic device 12 is provided in the deodorizing device storage chamber 8. I have. In the photocatalyst device 12 and the ozone decomposition catalyst 13, the photocatalyst device 12 is located on the upstream side, that is, on the suction port 3 side, and the ozone decomposition catalyst 13 is located on the downstream side.

A blower 16 as a blower is provided in a lower portion of the main body case 2. This blower 16
It comprises a motor 17 and a fan 18 driven to rotate by the motor 17. The motor 17 is mounted in the mechanism room 7, and a horizontal rotation output shaft 19 of the motor 17 extends to the fan housing 9. The fan 18 is attached to the rotation output shaft 19 in the fan storage chamber 9. As the fan 18, a sirocco fan is used because it requires a static pressure. The partition wall 9a for partitioning the fan storage chamber 9 has a substantially cylindrical shape coaxial with the fan 18, the opening at the end face is on the suction side, and the opening at the lower peripheral surface is the discharge port 4. ing. When the rotation output shaft 19 of the motor 17 rotates, the fan 18 also rotates, whereby the room air is sucked into the suction port 3 from above and the air passage 5 in the main body case 2 is opened.
Through the outlet 4 and is discharged downward. In addition,
As is clear from the above description, the deodorizing device 14 is located on the upstream side of the fan 18 of the blower 16, that is, on the suction side.

The circulator main body 1 is mounted on an indoor wall 22 by a wall mounting means 21 as a mounting means. Next, the configuration of the wall mounting unit 21 will be described. At the upper part of the rear surface of the main body case 2, a substantially metal-shaped hook 23 is projected and fixed upward, and a slit 24 is located below the hook 23.
Are formed. Reference numeral 25 denotes a wall-mounting bracket, and the wall-mounting bracket 25 is attached to the indoor wall 22 with a wood screw 26. A substantially L-shaped hook portion 27 is formed so as to protrude forward at an upper portion of the wall mounting bracket 25, and a projection 28 is formed at a lower portion of the wall mounting bracket 25 so as to protrude forward. Then, the hook 23 of the circulator body 1 is hooked on the hook portion 27 of the wall hanging bracket 25, and the projection 28 of the wall hanging bracket 25 is slit into the slit of the circulator body 1.
The circulator body 1 is attached to the indoor wall 22 by being fitted into the inside 24.

Next, the discharge light excitation type photocatalyst device 12
Will be described with reference to FIG. This photocatalyst device 12
Holds the discharge electrode 32 between the pair of bases 31 supporting the photocatalyst, and further holds the base 31 to the pair of ground electrodes 33.
It is configured to be sandwiched between. Then, a discharge is performed between the central discharge electrode 32 and the ground electrodes 33 on both sides. At this time, light in the ultraviolet region is emitted, and the light promotes the decomposition reaction of the photocatalyst to deodorize.

Next, the operation of the above configuration will be described. In FIGS. 1 and 2, thick arrows without reference numerals indicate the flow of air. The air in the room is heated by using the heater, but the warm air is divided into the upper part of the room and the cool air is divided into the lower part of the room. Therefore, when driving this circulator,
By driving the blower 16, warm air containing dust in the room is supplied to the suction port 3 in the upper part of the circulator body 1.
From the air passage 5 in the circulator body 1.
At that time, relatively large dust such as cotton garbage
It is collected and removed by the pre-filter 11 covering the. Next, air passes through the photocatalyst device 12 and further through the ozone decomposition catalyst 13, but collection by the pre-filter 11 prevents relatively large dust from entering the photocatalyst device 12, thereby suppressing clogging of the photocatalyst device 12. Is done. When air comes into contact with the photocatalyst, ammonia, acetic acid, etc., which are malodorous components contained in the air, or formaldehyde, which is a causative substance of sick house disease, are decomposed into harmless substances, and the malodor is removed. At that time, ozone is generated from the photocatalyst device 12. Although it is said that ozone may have an adverse effect on the human body, this ozone is decomposed by the ozone decomposition catalyst 13 and is not released out of the circulator body 1. The air that has flowed out of the ozone decomposition catalyst 13 passes through the fan storage chamber 9 and is discharged downward from the discharge port 4 at the bottom of the circulator body 1.

A part of the air sucked into the circulator body 1 from the suction port 3 passes through the bypass section 10 without passing through the photocatalyst device 12 and the ozone decomposition catalyst 13 as shown by an arrow A in FIG. However, it is not essential to provide such a bypass unit 10.

As described above, the circulator draws the air in the upper part of the room and blows it out, so that the warm air in the upper part of the room is sent to the lower part of the room, and the air in the room circulates and convects. Thereby, the temperature distribution in the room becomes constant. In addition to such an original function of the circulator, the present circulator has a deodorizing function of decomposing and removing malodorous components in the room. Moreover, the deodorizing device 14 is composed of the photocatalytic device 12 of the discharge light excitation type and the ozone decomposition catalyst 13.
Therefore, deodorization can be performed more reliably and harmful substances can be removed. Further, the pre-filter 11 can collect dust from indoor air. Therefore,
A comfortable indoor environment can be created.

Also, since the deodorizer is a wall-mounted type, a floor-standing type deodorizer requires an installation space, whereas a space saving on the floor can be achieved.

It should be noted that the present invention is not limited to the above embodiment, and various modifications can be made. For example,
In the above embodiment, the pre-filter 11 is provided at the suction port 3 in the dust collecting device. However, a dust collecting device such as a HEPA filter or an electric dust collecting device may be provided separately from the pre-filter 11. Thereby, dust can be more reliably removed from the indoor air, and a more comfortable indoor environment can be created. In the above embodiment,
Although the deodorizing device 14 is the photocatalytic device 12 of the discharge light excitation type and the ozone decomposing catalyst 13, activated carbon or the like can be used as the deodorizing device. Further, in the above embodiment, the blower 16
Although the deodorizing device 14 is disposed on the suction side of the fan, the deodorizing device 14 may be disposed on the discharge side of the blower 16. When the deodorizing device 14 is provided on the discharge side of the blower 16 in this manner, deodorizing is performed at the last stage when air is discharged from the circulator, so that the deodorizing effect can be enhanced.
