Abstract

PURPOSE:To obtain an air cleaner not using a vinyl sheeting which would contribute to growth of microorganism such as mold, by providing nozzle parts for obtaining air curtain airflows between the outer periphery of a support frame and an inner periphery of a main body casing. CONSTITUTION:With a blower 15 operated, the outside air is sucked in through an air suction port 18, is cleaned while flowing through a high-performance air filter 17, and is blown off from a clean air blow-off opening part 16, as indicated by arrows C. A portion of the air sucked in is caused to flow outward by the flow resistance in the filter 17, and flows through nozzle parts 21 provided between the outer periphery 19 of a support frame 17a and the inner periphery 20 of a main body casing 14. As a result, air curtain airflows are generated as indicated by arrows A, B to separate a clean air region D below the opening part 16 from an unclean air region E. Accordingly, it is unnecessary to use a vinyl sheeting or the like, passage of persons or articles into or out of the region D can be easily achieved without troubles such as a trouble to tuck up a curtain, smoothness of operations is enhanced, and an advantage on a hygienic basis is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an air cleaning device for locally cleaning air in a work area.

BACKGROUND OF THE INVENTION Conventionally, as shown in FIG. 2, this type of air purifying device has a main body casing 4 that includes a blower chamber 2 and an air filter chamber 3 separated by a partition plate 1. is equipped with a blower 6 and a high-performance air filter 7 held in the air filter chamber 3 with a holding fitting 6 interposed therebetween. On one side of the blower room,
An air suction port 8 is provided which opens to correspond to the amount of air sucked in by the blower 5. The lower part of the main body casing 4 is divided into an air clean area and a non-clean area, and a curtain 9 made of vinyl is hung from above to prevent air flow from entering the clean area from the non-clean area. and blower 5
By operating the , outside air flows in through the suction port 8 , and the air is purified by the blower 6 through the high-performance air filter 7 in the air filter chamber 3 and then sent to the curtain 9 .
It was meant to be sent inside. 1Q is the bolt for hanging the air purifier.

Problems to be Solved by the Invention In such a conventional configuration, a curtain 9 made of a vinyl sheet or the like is hung down to separate a clean area and a non-clean area, so that it is difficult for people to enter and leave the clean area and for goods to be transferred. Curtain 9 for entry and exit
In addition, it is inconvenient to have to pull up the hem of the curtain 9, and furthermore, the curtain 9 is often made of transparent vinyl sheet made of synthetic resin, so it cannot be used in places with high humidity such as food factories, or where water droplets may adhere. In places where the toilet is used, the vinyl sheet curtain 9 becomes a source of microorganisms such as mold, and is extremely unhygienic.

The present invention solves these problems by separating clean areas and non-clean areas without using curtains such as vinyl sheets, so that the hem of the curtain can be used when people or goods are entering and exiting. The object of the present invention is to provide an air purifying device that eliminates the complication of having to tuck it up and does not use vinyl sheets, which can be a source of microorganisms such as mold.

Means for solving the problem In order to solve this problem, the present invention has a main body casing with an opening for sucking in external air, and a blower and an air filter such as a high-performance type are held within this main body casing. a holding frame provided with a clean air blowing opening below the high-performance air filter;
A nozzle portion is provided for obtaining an air curtain airflow formed between the outer periphery of the holding frame and the inner periphery of the main body casing.

Function: With this configuration, when the blower is operated, external air flows in from the air inlet, the incoming air is purified through a high-performance air filter, and blown out through the clean air blowing opening. The air passes through a nozzle section provided between the outer periphery of the clean air blowing opening and the inner periphery of the main body casing, and becomes an air curtain airflow that separates the air from the clean area and non-clean area below the clean air blowing opening. It will be divided into two areas.

Example An embodiment of the present invention will be described below based on FIG.

A blower chamber 12 partitioned by a partition plate 11 and an air filter chamber 13 are formed inside the main body casing 14, and the blower chamber 12 is provided with a blower 15,
The air filter chamber 13 has an opening 16 for blowing clean air.
It is provided with a holding frame 17a that holds a high-performance air filter 17 provided below. An air suction port 18 is provided on one side of the main body casing 14 and is opened to correspond to the amount of air sucked in by the blower 15 . A nozzle portion 21 is formed by providing a space between the outer periphery 19 of the holding frame 17a constituting the clean air blowing opening 16 and the inner periphery 2o of the main body casing 14.

22 is a bolt for hanging the air purifier. In the above configuration, by operating the blower 16, external air flows in through the air suction port 18, and the inflowing air is purified through the high-performance air filter 17, as indicated by the arrow C.
As shown in FIG. 3, while being blown out from the clean air blowing opening 16, a part of the inflowing air goes around the outside due to the resistance of the high performance air filter 17 and is connected to the outer periphery 19 of the holding frame 1a and the main body casing 14. By passing through the nozzle part 21 provided between the inner circumference 20 of the arrow A,
The air curtain airflow shown in B divides the air from the clean area below the clean air blowing opening 16 to the non-clean area E.

As described above, according to this embodiment, it is possible to very easily divide the air-cleaned area and the non-cleaned area E without using curtains such as vinyl sheets, and it is possible to separate the air-cleaned area and the non-cleaned area E without using curtains such as vinyl sheets. There is no need to tuck up the hem of the curtain upwards, and the work becomes much smoother. Furthermore, by eliminating the use of curtains such as vinyl sheets, which tend to be a source of microorganisms such as mold in food factories, it is possible to provide an air purifying device that is extremely hygienic.

Effects of the Invention As is clear from the above description of the embodiments, according to the present invention, air that flows in from the outside by a blower is purified through a high-performance air filter, but a portion of the air that flows in is filtered through the nozzle. Since the airflow becomes airflow through the air curtain and separates the air-cleaned area from the non-cleaned area, there is no need to use conventional curtains such as vinyl sheets. The smoothness of the work is improved without the complication of raising the number by 7. Furthermore, by eliminating the use of curtains such as vinyl sheets, which can easily become a source of microorganisms such as mold in food factories, the system is extremely hygienic and has great industrial effects.
