Hereinafter, an air blow device and a compressor according to embodiments for carrying out the present invention will be described with reference to the drawings.

The air blow device 1 according to the present embodiment includes a compressor 100 and a nozzle 200 for blowing compressed air sent from the compressor 100, as shown in FIG.

A plurality of nozzles 200 are provided and attached to an air distributor 210 via a flexible pipe 220 . Compressed air blown out from the nozzle 200 removes water after washing and cutting dust adhering to the work. The air distributor 210 is fixed to the fixed base 230 and distributes the compressed air sent from the compressor 100 to each nozzle 200 . The flexible pipe 220 can be freely bent by hand and can maintain its bent shape. One end of a pipe 240 is attached to the air distributor 210 . The other end of the pipe 240 is attached to a discharge port 150 of the compressor 100, which will be described later.

As shown in FIGS. 2 to 6, the compressor 100 includes a compressor (blower) 110 for compressing air, a motor 120 for driving the compressor 110, an air filter 130 for removing dirt and dust from the air, and an air a suction unit 140 in which a filter 130 is arranged; a discharge port 150 for discharging air compressed by the compressor 110; It includes a second pipe 170 that guides air to the outlet, a control unit 300 that controls the motor 120, and a housing 400 that stores the components described above.

Compressor 110 is a centrifugal compressor, compresses air that has passed through air filter 130 , and discharges the compressed air from outlet 150 . The compressor 110 compresses air by sending air radially outward (centrifugally) with an impeller and decelerating the sent air with a diffuser.

The motor 120 electrically drives the compressor 110 and is arranged in the lower part of the housing 400 together with the compressor 110 . The motor 120 is composed of a single-layer AC-DC motor, a three-phase AC-DC motor, or the like, and preferably has an output of 1.5 to 3.7 kW. For example, if a 1.5 kW motor 120 is used to drive the compressor 110, an air flow rate of 2.0 m ³ /min can be obtained.

The air filter 130 is arranged in an opening provided in the upper half of the front face of the housing 400, and removes dirt, dust, fine particles, etc. from the air. 3 and 4, the air filter 130 includes a primary filter 131, a secondary filter 132 arranged downstream of the primary filter 131, and a tertiary filter 132 arranged downstream of the secondary filter 132. 133 and . The primary filter 131 is made of mesh with an opening of 1.0 mm, and removes dust and the like from the air. The secondary filter 132 is made of nonwoven fabric and mainly removes dust of 1 μm or more. The tertiary filter 133 is composed of a bellows-folded HEPA (High Efficiency Particulate Air) filter and removes particulates that have passed through the secondary filter 132 . By disposing the secondary filter 132 upstream of the tertiary filter 133, the tertiary filter 133 is less likely to be clogged. The tertiary filter 133 is bellows-folded to increase the area of the HEPA filter and reduce the pressure loss of the air passing through the filter.

The suction part 140 has a truncated pyramid shape with an upper base 141 closed and a lower base 142 opened, and introduces air that has passed through the air filter 130 into the first pipe 160 . The suction unit 140 is arranged such that the air filter 130 is positioned on the bottom 142 . A first pipe 160 is attached to the conical surface 143 of the suction part 140 . A soundproof sheet 144 is attached to the inner surface of the suction unit 140 . The suction unit 140 has the shape of a truncated pyramid, and the first pipe 160 is attached to the pyramid surface 143, so that the depth of the housing 400 can be reduced.

The discharge port 150 is arranged on the top plate of the housing 400 and discharges the air compressed by the compressor 110 . A pipe 240 or the like for guiding the compressed air is attached to the outlet 150 .

The first pipe 160 has one end attached to the suction unit 140 and the other end attached to the intake port of the compressor 110 to guide air from the suction unit 140 to the compressor 110 . The second pipe 170 has one end attached to the exhaust port of the compressor 110 and the other end attached to the exhaust port 150 to guide compressed air from the compressor 110 to the exhaust port 150 .

The control unit 300 includes an inverter or a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and a timer, and controls ON/OFF of the motor 120 . The control unit 300 may turn the motor 120 ON or OFF according to the user's operation. Control unit 300 may turn motor 120 ON or OFF at a set time. For example, the control unit 300 turns on the motor 120 at 8:00 and turns off the motor 120 at 17:00. Further, the control unit 300 may turn off the motor 120 after the set period has elapsed. For example, the control unit 300 turns off the motor 120 after three hours have passed since the motor 120 was turned on.
When control unit 300 turns on motor 120 , motor 120 drives compressor 110 . Thereby, the compressor 110 compresses the air sucked through the air filter 130 and discharges the compressed air from the discharge port 150 .

The housing 400 accommodates each configuration from the compressor 110 to the second pipe 170 and the control unit 300 described above. As shown in FIGS. 6A to 6E, the housing 400 has a rectangular parallelepiped shape in which the length H in the vertical direction is longer than the depth D and the length W in the width direction. The length D of the depth is smaller than the length W in the width direction. An opening is provided in the upper part of the front face of the housing 400, and the air filter 130 is attached.

Compressor 100 having the above configuration has air filter 130 attached to the upper part of the housing, and compressor 110 and motor 120 arranged in the lower part of the housing. Therefore, the compressor 100 discharges compressed air free of particulates and can be placed on a floor with a small area. In addition, since the suction unit 140 has a truncated pyramid shape and the first pipe 160 is attached to the pyramid surface 143, the depth of the housing 400 can be reduced. In addition, since the discharge port 150 is arranged on the top plate of the housing 400, it does not interfere with the transportation of workers and loads, and the rear and side surfaces of the compressor 100 can be arranged without leaving a gap between them and the wall. can. On the other hand, if the discharge port 150 is arranged on the side surface of the housing 400, there is a danger that the worker or the load being transported will get caught. The nozzle 200 is attached via a flexible pipe 220, and the flexible pipe 220 can be freely bent by hand and can maintain its shape while being bent. Therefore, the direction in which the compressed air is blown out from the nozzle 200 can be freely changed.

(Modification)
In the above-described embodiment, the suction unit 140 has a truncated pyramid shape, but the suction unit 140 is not particularly limited as long as it has a truncated pyramid shape. For example, the suction portion 140 may have a truncated cone shape. Also, the lower base and upper base of the frustum may not be parallel.

Although an example in which a plurality of nozzles 200 are provided has been described in the above-described embodiment, one nozzle 200 may be provided.

The present invention is capable of various embodiments and modifications without departing from the broader spirit and scope of the invention. Moreover, the embodiment described above is for explaining the present invention, and does not limit the scope of the present invention.
