The inside of the main body 1 is divided into upper and lower parts by a partition plate 11, a blower device 12 and a dust collecting container 13 are provided in the upper section, and a compressor 14 is provided in the lower section. Since the compressor 14 is not required when connected to an external air tank, the lower section is used for storing tools and the like. A suction duct 15 connected to the boom 6 and an exhaust duct 16 connected to the exhaust port of the main body 1 are attached to the dust collecting container 13, a filter 17 is attached therein, and the dust collecting container 13 is detachably attached by an operation lever 18.

The main body 1 is designed on the assumption that it is installed outdoors. In particular, it is assumed that rainwater invades from the joint S between the side plate 1a and the back plate 1b, and the infiltrated rainwater is infiltrated into the main body 1. As shown in FIG. 4, the edge L1 of the back plate 1b is bent at a right angle to form a U-shaped or V-shaped hemming edge L2 on the side plate 1a so as not to enter the inside, and the edge of the back plate 1b is formed. The structure is such that L1 fits. As a result, the rainwater that has entered from the joint V between the side plate 1a and the back plate 1b is received by the hemming edge L2 and drops downward as it is, so that the intrusion into the main body can be prevented.

With such a configuration, when the blower device 12 is operated, a suction path from the suction duct 15 to the suction nozzle 7 through the boom 6 and the suction hose 8 is formed, and dust can be sucked from the suction nozzle 7. The sucked dust is taken into the dust collecting container 13, separated by the filter 17, and then exhausted to the outside air through the exhaust duct 16.

FIGS. 5 to 7 show the configuration of the suction nozzle 7.
The suction nozzle 7 has a nozzle body 20 having a vertically long suction port 20a formed at the tip and a cylindrical connecting cylinder 20b formed at the rear end, and a fitting cylinder 21a into which the connecting cylinder 20b of the nozzle body 20 is fitted at the front end. It is composed of a nozzle base 21 which is formed and has a connecting cylinder 21b to which a suction hose 8 is connected to the rear end.

A soft resin material is used for the nozzle body 20 in consideration of the cleaning surface, and the suction port 20a is inclined so that the lower part is shortened in a side view so that the nozzle body 20 can easily act on a narrow gap or an undulating cleaning surface. doing. As shown in FIG. 5, a warning mark 22 is engraved on the side surface of the nozzle body 20 to prohibit the inhalation of cigarettes or liquids that cause mechanical failure. Further, inside the nozzle body 20, a regulating rib 23 is provided to limit the size of dust to be sucked in, such as tissue and vinyl, which causes a decrease in suction force and clogging of the hose. Further, an air chamber 25 for accommodating the air hose 24 is integrally formed on the lower surface of the nozzle body 20.

The caution mark 22 is represented by a pictogram showing a figure of a suction prohibited object such as water droplets or cigarettes in a general prohibition mark (diagonal line in a circle), and is integrated on the left and right side surfaces of the nozzle body 20. Is engraved on. As a result, the risk of the warning notation disappearing is lower than in the case of sticking a sticker, and it is possible to continuously call attention to prohibited objects.

As shown in FIG. 6, the regulation rib 23 is formed so as to project inward from the left and right inner walls of the nozzle body 20 so as to vertically (vertically) divide the suction port 20a in the longitudinal direction (vertical direction). The ribs are arranged so that a gap S is formed between the tips of the ribs. The gap S is for making it difficult for lint, hair, and the like to get caught in the rib 23. The regulation rib 23 extends horizontally from the tip of the suction port 20a toward the suction direction of the nozzle body 20, and its end position matches the position where the caution mark 22 is engraved. As a result, when the suction port 20a of the nozzle body 20 is worn down due to wear, the remaining regulation rib 23 can be confirmed with reference to the position of the caution mark 22, and the replacement timing of the nozzle body 20 can be known.

The nozzle base 21 is formed in a lateral view at the horizontal portion and the bent portion, the connecting cylinder 20b of the nozzle body 20 is fitted to the fitting cylinder 21a at the front end, and the suction hose 8 is fitted to the connecting cylinder 21b at the rear end. Is connected. A valve accommodating chamber 27 for accommodating an air valve 26 connecting the air hose 10 and the air hose 24 is formed on the lower surface of the horizontal portion, and a grip 28 for the user to grip the nozzle 7 is formed on the bent portion.

The air valve 26 is opened and closed by the operating lever 29, and the high-pressure air sent from the air hose 10 is discharged to the air hose 24 side. The operation lever 29 is provided at a position where the user can operate the grip 28 while holding the grip 28, and the distance between the grip 28 and the lever 29 is set so as not to get in the way when the lever 29 is not used. Here, the distance between the grip 28 and the lever 29 is set within a range that the user can reach by extending the finger while holding the grip 28 without hindering the grip 28, and this distance is set as a spring (not shown). ) To prevent rattling of the operating lever 29 when not in use.

As shown in FIG. 7, the nozzle body 20 and the nozzle base 21 are connected by fitting the connecting cylinder 20b of the nozzle body 20 into the fitting cylinder 21a of the nozzle base 21. Locking hooks 30 are formed on the outer peripheral surface of the connecting cylinder 20b, and ribs 31 are formed at three positions on the inner peripheral surface of the fitting cylinder 21a along the insertion direction of the nozzle body 20 and are locked. A locking hole 32 into which the hook 30 is fitted is formed. As a result, when the connecting cylinder 20b is fitted into the fitting cylinder 21a, the peripheral surface of the connecting cylinder 20b is press-fitted while sliding in contact with the rib 31, and the locking hook 30 is fitted into the locking hole 32 to hold the engagement. This makes it possible to reduce joining defects due to variations in the dimensions of the parts, and to easily replace the nozzle body 20.

The vacuum cleaner configured in this way is installed in a service station, a coin car wash, etc. for cleaning the inside of the vehicle. Although not particularly shown, the operation unit 2 on the front surface is provided with a coin mech, and when a predetermined amount of money is input, the blower device 12 is activated to enable dust collection work. When the blower device 12 is activated, the inside of the vehicle can be cleaned using the suction nozzle 7 as described above. Further, the compressor 14 is also activated, and high-pressure air is supplied to the suction nozzle 7 through the air hose 15. Therefore, by opening the air valve 26 with the operation lever 29 as necessary, air is blown from the air hose 24 to the cleaning surface. The dust can be floated and then sucked by the suction nozzle 7.

After many years of use, the tip of the nozzle body 20 of the suction nozzle 7 becomes worn. As a result, the regulation rib 23 that limits the size of the dust to be sucked in is worn down and does not perform its original function. Since the regulation rib 23 is provided so as to match the position of the warning mark 22 engraved on the side surface of the nozzle body 20, when the tip of the nozzle body 20 wears to the position of the warning mark 22, it is time to replace the nozzle body 20. Is recognized. The nozzle body 20 can be removed from the nozzle base 21 by removing the locking hook 30 from the locking hole 32, and can be easily replaced.
