Abstract

PURPOSE: To obtain an air conditioner in which the effect of an antibacterial agent is performed for a long period by forming the component member of a blower by a synthetic resin material in which the agent is added to a cyclopolyolefin resin. CONSTITUTION: An air conditioner 1 sucks the air from the suction port 33 of a suction grill 34 by the operation of a supply fan 22, removes dusts by an air filter 31, then regulates the temperature by a heat exchanger 17, and diffuses from an air outlet 29 to indoor via wind direction altering blades 35, 27, 28. In this case, component members (22, 27, 29, 31, 32, 34, 35, etc.) in contact with the air and a sheath (40, 41, etc.) are formed by a cyclopolyolefin resin in which an antibacterial agent is added (0.5 to 2.0 wt.% of the entire weight), thereby gradually impregnating the agent to the front surface and performing antibacterial action for a long period.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air blower for circulating air and an air conditioner for adjusting the temperature inside a room.

[0002]

2. Description of the Related Art As a conventional technique of this type, for example, there is one disclosed in Japanese Patent Publication No. 40560/1992. This publication discloses a technique of coating the surface of a fan made of synthetic resin with an anti-fouling paint.

[0003]

Since the blower fan is coated with antifungal (prevents mold) paint,
Although it can be expected to have a deterrent effect, the paint may gradually come off due to long-term use, and a coating operation is required, which causes a cost increase.
Therefore, we do not want to perform coating work as much as possible.

The present invention provides a sanitary blower and an air conditioner for many years.

[0005]

In order to solve the above problems, the first invention is a blower for circulating air, in which a constituent member of the blower is a cyclic polyolefin resin to which an antibacterial agent is added. It is made of a synthetic resin material.

A second aspect of the present invention is an air conditioner provided with a blower for sucking and blowing air, wherein the blower is made of a synthetic resin material obtained by adding an antibacterial agent to a cyclic polyolefin resin. Is.

A third aspect of the present invention is an air conditioner equipped with a blower for sucking in and blowing out air, wherein the constituent members of the portion in contact with air are synthesized by adding an antibacterial agent to a cyclic polyolefin resin. It is made of resin material.

Further, according to the fourth aspect of the invention, in an air conditioner equipped with a blower for sucking in and blowing out air, the blower or a component in contact with the air is 0.5 wt% of a cyclic polyolefin resin. It is made of a synthetic resin material to which an antibacterial agent is added in an amount of up to 2.0% by weight.

[0009]

In the air blower according to the first aspect of the invention and the air conditioner according to the second aspect of the invention, the blower is formed of the synthetic resin material in which the antibacterial agent is added to the cyclic polyolefin resin.
There is no need to coat anti-fouling paint, and there is no risk of the antibacterial agent running off. Moreover, the antibacterial agent added to the cyclic polyolefin resin gradually leaches (bleeds) onto the surface of the blower.

Further, in the air conditioner of the third invention, the antibacterial agent added to the cyclic polyolefin resin gradually seeps out to the surface of the portion in contact with air.

Further, in the air conditioner of the fourth invention, since the antibacterial agent is 0.5% to 2.0% by weight, the strength of the synthetic resin material is not lowered so much.

[Examples] 1.0 wt% benzimidazole antibacterial agent to cyclic polyolefin resin (diphenyl ethers, N-haloalkylthios, organic arsenic, etc. may be used)
Synthetic resin formed by adding
3) and other amorphous resin (for example, PS resin, AS-G)
Table 1 shows the results of a halo test performed on synthetic resins (comparative examples) formed by adding the antibacterial agent to samples 4 to 6) such as resin and ABS resin. This hello test
7 in the initial stage (Samples 1 and 4) and at a temperature of 70 ° C
The test was performed after a lapse of days (Samples 2 and 5) and after a lapse of 7 days (Samples 3 and 6) in a state of being immersed in running water of 1 liter / min. In the case of the present application (Samples 1 to 3), a halo (growth arrest zone) was confirmed at any time and under any conditions, and the effect of the antibacterial agent was confirmed. However, in all of the comparative examples (Samples 4 to 6), the halo was not formed, and in the amorphous resin to which the antibacterial agent was added, the effect of the antibacterial agent was observed only in the cyclic polyolefin.
