2. Description of the Related Art Conventionally, as a technique for constructing an air shower chamber, a technique for continuously discharging air of a predetermined flow velocity into the air shower chamber using a nozzle and applying the air to clothes or the like to remove dust or the like, In addition, there is known a technique in which air having a predetermined flow rate is intermittently discharged to an air shower chamber using a nozzle and the air is applied to clothes or the like to remove dust and the like. In this case, a nozzle that continuously discharges air and a nozzle that intermittently discharges air are arranged in the air shower chamber, and dust and the like are normally removed using the nozzle that continuously discharges air. At the same time, it is known to remove dust or the like, so to speak, by "manipulating water" by directing a nozzle that discharges air intermittently, particularly in a heavily soiled area.

In the above-mentioned conventional technique, the air shower user appropriately uses the nozzle for continuously and intermittently ejecting air to remove normal dust and the like, and particularly to remove dust and the like in a heavily soiled portion. Is to do.
That is, this is a technique in which a nozzle for intermittently ejecting air is manually operated and used in combination with a nozzle for continuously ejecting air as appropriate. According to this conventional technique, the use of different types of nozzles when removing dust etc. is left to the judgment of the air shower user, and the user intermittently turns on the air while checking the progress of dust removal. It was necessary to manually judge the nozzles to be discharged to the above.

The above-mentioned problems can be solved by the invention described in each claim. According to the invention of claim 1, the first nozzle for continuously ejecting air and the second nozzle for intermittently ejecting air eject air in the same direction. As a result, for example, two kinds of air (air as a continuous flow and air as an intermittent flow) are constantly discharged to dust or the like attached to clothes, so that only one air flow is used. Will be removed more effectively than the above. That is, as a result of both nozzles ejecting air in the same direction, continuous air and intermittent air are superposedly ejected on the dust or the like to be removed, so that a high dust removing effect is achieved. It will be. The term "dust and the like" used in the present specification broadly includes not only dust itself but also fly ash containing harmful substances such as dioxins, pathogens such as pollen and viruses, and tobacco particles. In the present invention, since two types of different modes of air are discharged in the same direction, it is not necessary for the user to operate the nozzle to superimpose one air flow on the other air flow. In the present invention, it is preferable that the air discharge speed of the second nozzle is equal to or faster than the air flow speed of the first nozzle. In this case, the faster the intermittent flow of the air blown against the dust or the like is, the more the effect of knocking off the dust or the like is expected.

Further , according to the invention of claim 1, one of the first and second nozzles is provided in the other nozzle so as to be integrally movable, and both nozzles have the same direction. Air will be discharged toward. Contract
According to the invention of Motomeko 2, the discharge speed of the air in the second nozzle is configured to be faster than the discharge velocity of the air in the first nozzle. In this case, the earlier the intermittent flow of the air blown onto the dust or the like is expected, the effect of knocking off the dust or the like is expected. As a positional relationship between both nozzles, it is preferable that a second nozzle that intermittently discharges air be provided in the first nozzle that continuously discharges air. In this case, it is preferable that the second nozzle be configured as a higher pressure air nozzle than the first nozzle. When the second nozzle is provided in the first nozzle, the continuous air flow is widely blown to the dirt, and the intermittent air flow is supplied toward the center of the dirt to remove dust and the like. The effect can be expected more.

According to the invention of claim 3, an air shower chamber having a plurality of the air shower nozzles according to claim 1 or 2 having the above-mentioned characteristics is arranged and a high dust removing effect is provided. It will be.

Further, in the air shower room according to claim 3,
There, air is discharged downward to the ceiling.

According to the "work chamber" , in the air shower chamber according to the third aspect, in addition to the above-described air shower nozzle, a nozzle that further discharges air downward is arranged in the ceiling portion. Therefore, the dust and the like removed from the clothes and the like by the air shower nozzle are moved to the lower side of the air shower chamber by the air discharged from the nozzle and collected.

[0009] And "the air shower room according to claim 3
However, there is a grating on the floor.
The projections are formed on the surface of the grating at regular intervals.
According to the "air shower room" , the air shower room according to claim 3 is provided with a grating on the floor thereof. The grating is a floor frame configured in a lattice shape, and is formed by using, for example, metal or hard resin. Book
In the configuration , protrusions are formed on the surface at predetermined intervals. The protrusion is used by the user of the air shower room to scrape off the dirt adhering to the sole. That is, this air shower removes dust and the like adhering to clothes and the like by using an air shower nozzle that uses two types of nozzles that continuously and intermittently discharge air in the same direction, and uses the grating. It is possible to remove the dirt adhering to the shoe sole, and to provide a practical air shower room having a high cleaning ability.
