2. Description of the Related Art In order to maintain the quality of ultra LSIs such as semiconductor memories and microprocessors and precision products, work is generally performed in a clean room in a clean atmosphere. In such a clean room, the maximum particle size of dust remaining and floating in the work environment, the number of dust per unit volume, and the like are defined and managed according to the work content. Therefore, in a clean room requiring high cleanliness, high-performance filters are used to remove dust and mold contained in the outside air, remove microorganisms such as bacteria, harmful ions and the like, and take in purified air. The clean room is connected to an air shower room, a hand washing room, and a changing room, where workers wear dust-free clothes, dust-free hats, dust-free masks, and dust-proof shoes, and apply detergent before entering the clean room. Wash your hands using a filter and blow it through a filter to prevent foreign substances such as dust from re-adhering to dry.After that, put on dust-free gloves and enter the air shower room to blow off foreign substances on the outer surface. By removing, care is taken to prevent foreign matter from entering the clean room from outside. Here, as a dryer used for drying after hand washing, there are generally a dryer that evaporates moisture with heated air to dry and a dryer that blows moisture off with high-pressure air to dry. In the former, it takes time until the temperature of the air rises sufficiently by energizing the heating heater, it is difficult to adjust the air volume and heating, and if the water is removed in a short time, there is a risk of overheating and burns, and the temperature is low. It not only takes time to dry, but also has the drawback that the body temperature is deprived by the heat of vaporization and it feels cold, and if the detergent that causes dust is insufficiently rinsed, it cannot be sufficiently removed if it remains. There is also. In the latter, the pressure of the purified air is increased to a high
Since the water adhering to the blowing hand is blown away at a high speed of 100 m / s to remove the water, it can be dried in a short time, and does not feel too cold due to stimulation by high-speed air. on the other hand,
Workers entering and leaving the clean room concentrate on the shift time of work, and a large number of workers flood from the changing room into the air cleaner room in a short time. Therefore, it is important that drying can be performed reliably in a short period of time, including the removal of the residual detergent. In this regard, the latter dryer is superior. One example of such a dryer is disclosed in JP-A-61-109532. This is shown schematically in FIG. In the figure, reference numeral 1 denotes a vertically long main body box, in which intake ports 1a and 1a are formed in an upper wall surface, and the inside is vertically separated by a partition wall 2 having a rectangular hole 2a, and a front surface below the partition wall 2 is dried. An insertion window 1b for inserting an object and exhaust ports 1c, 1c are formed on both side walls. Reference numeral 3 denotes a blower box having open upper and lower ends, and 4 denotes a buffer box provided with a blower 5 which takes in air from the upper surface, compresses the air, and sends the compressed air downward.
The sound-absorbing material 6 is adhered to a surface of the blower 5 where air compressed by the blower 5 hits, and the compressed air pushed out from the side surface of the sound-absorbing material is passed through the lower opening of the blower box 4. It is sent downward shown by the arrow in the figure. 7 is a filter chamber which is open at both upper and lower ends and communicates with the lower end of the blower box 3; 8 is an airflow resistance plate disposed at a communication portion between the blower box 3 and the filter chamber 7; In the filter, a large number of filter elements formed into a cylindrical shape, each axis is arranged in parallel with each other, adjacent portions at both ends of each filter element are alternately closed, and the axis of each filter element is arranged in the vertical direction. is there. The air sent into the high-performance filter 9 through the airflow resistance plate 8 is taken in from the opening of the filter element but is closed at the lower end.
It is fed into the adjacent filter element whose upper end is closed and whose lower end is opened, and is taken out from the lower end opening of the filter chamber 7. Reference numeral 10 denotes a compressed air chamber having an open upper surface, connected to the filter chamber 7, and having an outlet nozzle 10a opened on the lower surface. The blower box 3, the filter chamber 7, and the compressed air chamber 10 are connected and integrated. This integrated body is housed in the main body box 1, and is engaged with the partition 2 at a flange portion formed on the outer periphery of the upper end of the compressed air chamber 10. I have. This device sends air taken in from an upper intake port 1a of a main body box 1 to a blower 5, compresses the air in the blower box 3, removes foreign matter in the air by a high-performance filter 9 in a filter chamber 7, and The air pressure is increased in the compressed air chamber 10, and high-pressure air blown out from the blowing nozzle 10a is applied to an object to be dried, for example, a wet hand inserted from the insertion window 1b, to blow off moisture and foreign matter attached to the hand, thereby removing moisture and foreign matter. Is removed from the exhaust port 1c, and the air cleaned by the high-performance filter 9 can be blown at a high pressure. Therefore, it is preferable as a hand-washing dryer attached to a clean room.

However, when the pressure shock of the air compressed by the blower 5 is applied to the high-performance filter 9 at the start of operation, the device shown in FIG. Compressed air chamber 10
The deformation of the filter element opened to the side becomes uneven, and the joint of each adjacent filter element is distorted and may be damaged when repeatedly operated. Therefore, the movement path of the compressed air is bent using the buffer box 4. The high-pressure air does not directly hit the high-performance filter 9 and the pressure is reduced by the airflow resistance plate 8.
Even if the pressure of the air compressed by the blower 5 stabilizes, it acts as a resistance, so that the pressure applied to the filter chamber 7 is reduced. As a result, the pressure of the air blown out from the compressed air chamber 10 is also limited. . On the other hand, if the material to be dried has an area spread like a wet hand, the drying time can be further reduced if high pressure air can be blown as a whole, but the pressure of the supply side air is limited. Therefore, when the number of the blowing nozzles 10a is increased, the pressure further decreases, and the drying takes a long time, contrary to the expectation of shortening the time by spraying the entire surface.
When a large number of workers are concentrated in a short period of time, waiting time is required.To solve this problem, it is necessary to arrange a large number of dryers, which requires a large installation area and increases noise. there were.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In a dryer according to the present invention, a sufficient space is formed in a filter chamber even after a filter member for separating a gas intake hole from a gas exhaust hole is disposed in the filter chamber. In this way, the filter chamber is connected to the compressed gas chamber, and the filter chamber itself has a function of compressing gas, and the pressure difference between the filter chamber and the compressed gas chamber is reduced, so that the filter The pressure shock applied to the element is reduced, and a large amount of high-pressure gas can be generated immediately after startup.However, the pressure is increased by forming a pressure-resistant part at a position facing the gas intake hole in the filter chamber. The filter member can be completely protected from gas impact. By converting the direction of the gas supplied by the pressure-resistant part to the direction of the inner wall of the filter chamber, it is possible to protect the filter member from gas impact and at the same time to increase the pressure in the filter chamber more quickly to supply the high-pressure gas. This pressure-resistant part can be formed directly on a part of the filter member in addition to being provided separately from the filter member. Further, the surface itself of the filter chamber facing the gas intake hole is used as the pressure-resistant part. be able to. By attaching a pressure-resistant part to the filter member, its gas intake surface can be oriented in any direction.However, the gas intake surface of the filter chamber should be arranged almost parallel to the axis of the gas intake hole of the filter chamber. By avoiding direct impact of the gas on the filter element during startup even without a pressure-resistant part in front of the gas intake surface, the performance of the filter member can be maximized and a large amount of high-pressure gas can be supplied. Can be.
