Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a cleaning device that can effectively capture and remove dirt and dust by using water as a filter, for example.

[Background of the invention]

The applicant of the present application previously proposed a cleaning device as shown in FIG.

In the figure, 1 is a water tank, 2 is an opening of the water tank 1 to which a pipe (not shown) having a nozzle at the tip is attached;
3 is a guide wall for configuring a guide path 4 guided from the opening 2 to the bottom side of the water tank 1; 5 is an output shaft of a motor disposed at the top of the water tank 1; 6 is a guide wall of the water tank 1; A separator with a slit is arranged so as to partition the upper opening and is attached to the lower part of the output shaft 5. Reference numeral 7 is a subaug, 8 is an air deflector, 9 is a motor housing, 10 is a motor cover, and 11 is a motor flange.

In the cleaning device with this configuration, when the power switch is turned on and the motor is activated, the fan rotates and air is sucked from the tip nozzle, passes through as shown by the arrows ab, c, and d to the motor housing 9 and the motor. It is discharged to the outside through the passage formed by the cover 10. At this time, the dirt and dust sucked together with the air from the tip nozzle pass through the water W in the water tank L, so the dirt and dust are The water W in the water tank 1 captures and removes dirt and dust, making it possible to effectively remove dirt and dust.

Note that the water W in the water tank 1 is also sucked together with the sucked air etc. by the operation of the suction means constituted by a fan, etc., and the separator 6 attached to the output shaft 5 of the motor
Water is drained by the rotation of , and the water W is configured so that it is not sucked into the paths of arrows c and d and does not enter them.

However, even with such a cleaning device, water sometimes gushes out to the outside, which poses a problem.

Further, there is a need for further improvement in the trapping and removal effects of dirt and dust.

[Disclosure of the Invention] While proceeding with the investigation into the problem of water spouting to the outside from the exhaust port in the cleaning device shown in FIG. We have now found out what is caused by this.

That is, the water-increasing type cleaning device that removes dust and drains water by rotating a separator 6 as shown in FIG. Only clean air is allowed to pass through the slits of the separator, and dust is scattered by the centrifugal force generated by the high speed rotation of the separator 6 and returned to the water tank 1.

The sealing between the outer edge of the rotating separator 6 and the housing of the device is achieved by the spider 7 and the motor flange 1.
1, a separator 6, etc., is adopted.

Incidentally, the dust (especially fibrous dust) that is not scattered by the centrifugal force travels along the outer wall of the separator 6 to the outer edge, and hits the motor flange inner wall 11a by the centrifugal force.
Some of the dust attached to the motor flange inner wall 11a overcomes the sealing force of the labyrinth, and in such cases, it passes through the gap between the spider 7 and the motor flange 11 and reaches the air deflector 8, causing the spider 7 and the air deflector 8 to As the water accumulates in the cavity formed by the dirt, the gap between the spider 7 and the motor flange 11 becomes clogged, and at this stage, water is sucked up through the clogged debris, resulting in a state of water gushing. I have come to the conclusion that this will be the case.

The inventor came up with the idea that it would be good to prevent water-containing dirt and dust from clogging the gaps, and as a result of further research, basically By making it difficult for dirt and dust to scatter from the water, it becomes difficult for water-containing dirt and dust to adhere to and accumulate in the gaps.
I came to a revelation that the problem of water gushing could be solved.

The present invention has been achieved based on the above revelation,
It is an object of the present invention to provide a cleaning device that does not spout water to the outside even during continuous operation for a long time.

Another object of the present invention is to provide a cleaning device that is effective in capturing and removing dirt and dust.

The object of the present invention is to provide a suction means, a liquid tank connected to the suction means, a suction port connected to the opening of the liquid tank, and suction from the suction port by the operation of the suction means. A cleaning device comprising a rotating separator with a slit provided between a suction means and the liquid in the liquid tank in order to shake off the liquid in the liquid tank that is pulled and sucked when It is distantly related to a cleaning device characterized in that a guide mechanism is constructed in the liquid tank, which promotes the liquid in the liquid tank to flow in a spiral shape by the operation of the suction means and the rotating separator. .

[Embodiment] Fig. 1 and Fig. 2 show one embodiment of the cleaning device according to the present invention, in which Fig. 1 is a sectional view of a main part, and Fig. 2 is a perspective view of a liquid tank.

In each figure, 21 is a water tank, 22 is an opening of the water tank 21 to which a vibrator is attached, which has a nozzle at its tip that serves as a suction port for dirt, dust, etc., and 23 is an opening from the entrance part 22 to the bottom side of the water tank 21. A guide wall 25 constitutes a guide path 24 to be guided, 25 is an output (rotation) shaft of a motor disposed on the upper part of the water tank 21, and 26 is arranged so as to partition the upper opening of the water tank 21. A separator with a slit is attached to the lower part of the output shaft 25, 27 is a spider, 28 is an air deflector, and 29 is a housing. Most of these structures are the same as those of the conventional cleaning device shown in FIG. Since this is a bit of a stretch, a detailed explanation will be omitted.

Reference numeral 30 denotes protrusions (wings) provided at appropriate positions on the lower surface of the outer peripheral edge 26a of the separator 26, for example, at four locations at 90-degree intervals.

In addition, in the cleaning device of this embodiment, a hanging portion 27a is provided on the outer peripheral portion of the spider 27, and the lower end portion of the hanging portion 27a is configured to be below the upper surface portion 21a of the water tank 21,
The outer peripheral edge 26a of the separator 26 is configured to be below the upper surface 21a of the water tank 21.

Therefore, in this cleaning device, there is no standing wall that connects to the gap 31 outside the separator 26 in the vicinity of the gap 31 formed between the separator 26, the motor flange 33, and the spider 27.

Further, the inner wall of the bottom surface of the water tank 21 is designed to prevent the water in the water tank 21 from being absorbed by the air, dirt, and dust from the nozzle when the suction means operates, until the dirt and dust travel through the guide path 24 and reach the separator 26. In order to stay immersed in W for as long as possible, the water tank 21 is configured to have a shape that promotes the water W in the water tank 21 to flow in a substantially spiral shape by the operation of the suction means and the separator 26. That is, a pot-shaped guide 24C is formed on the bottom surface 21b of the water tank 21, following the outlet 24a of the guide path 24.

Further, even when the cleaning device configured as described above was used for a long time, for example, continuously for 24 hours, no defects such as water spouting occurred.

That is, in the cleaning device of this embodiment, when the power switch is turned on and the motor is operated, the fan rotates and air is sucked from the tip nozzle, as shown by arrow a.

It passes through as shown in b, c, and d, and is discharged outside through the passage consisting of the motor housing 29 and motor cover 32. At this time, the dirt and dust sucked together with the air from the tip nozzle are discharged to the water tank. Since it takes a long time to pass through the water W in the water tank 21, dirt and dust are captured and removed by the water W in the water tank 21, and the dirt and dust can be effectively removed.

Then, the water W in the water tank 21 is sucked together with air etc. by the operation of the suction means constituted by a fan, and the separator 26 attached to the output shaft 25 of the motor
Water is drained by the rotation of , and the water W is not attracted to the paths shown by arrows c and d, but does not enter them.

That is, the air to be sucked and dust containing water are separated by a separator (separator slit) 26 rotating at high speed, only clean air is allowed to pass through the slit of the separator 26, and dust is separated by the centrifugal force generated by the high speed rotation of the separator 26. The water is scattered and returned into the water tank 21.

The seal between the outer edge of the rotating separator 26 and the motor flange 33 of the device is achieved by a labyrinth system formed by the spider 27, the motor flange 33, the separator 26, etc., as in the case of the cleaning device shown in FIG. However, dust that is not scattered by centrifugal force (particularly fibrous dust) travels along the outer wall of the separator 26 and reaches the outer edge. Since the installed wall was not located near the gap 31, water was not sucked up through the dirt, and the water gushing defect did not occur.

Incidentally, as a result of continuous operation of the cleaning device of this embodiment and the cleaning device shown in FIG. 3 after sucking water in which 20 g of cotton waste was dispersed, the cleaning device of this embodiment was operated continuously for 24 hours. However, in the cleaning device of the type shown in Fig. 3, water spewed out from the exhaust port after 5 hours, resulting in wetting the carpet.
