Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning machine used for window cleaning, car washing, etc.

[0002]

2. Description of the Related Art In cleaning windows and washing automobiles, water and detergent water are used to wash away dirt. Although water droplets remain on the cleaning surface, the water droplets include fine dust and other dirt even if they look fine. Therefore, if it is dried as it is, stains remain in the form of water drops or raindrops, which is unattractive.

Therefore, it is generally practiced to wipe off the water with a cloth such as a towel, but unless it is always wiped with a dry and clean surface, the dirt contained in the water droplets will be applied to the cleaning surface. The cleaning surface becomes dirty.

Therefore, in recent years, FIG.
A cleaning tool having a sponge at the tip of the handle as shown in FIG. The sponge has a larger water content than a towel, and when this cleaning tool is used to wipe the cleaning surface after washing with water, the sponge absorbs water droplets containing dirt.

However, there is a limit to the amount of water that the sponge can hold, and it is not possible to suck and hold more than a certain amount of water. To absorb and retain a large amount of water, the sponge can be made large, but this makes it difficult to use because of weight and handling. Further, when the sponge is pressed against the cleaning surface, the deformation of the sponge narrows the space for holding water in the sponge, and the water in the sponge reattaches to the cleaning surface and stains the cleaning surface.

Further, since dirt such as dust and sand dust that has been absorbed along with water drops remains in the sponge, if it is continuously used, the cleaning surface may be damaged by sand dust and the like adhering to the sponge surface,
Dirt will be applied to the cleaning surface.

Therefore, after a certain amount of use, it is necessary to wash the sponge with clean water to remove dirt, squeeze it and dry it to restore its water absorbing ability, which is inconvenient because it cannot be used continuously.

[0008]

Therefore, the present invention is used for cleaning window glass or cleaning with water such as car washing, and is capable of continuously absorbing moisture on the cleaning surface, and is compact without damaging the cleaning surface. A cleaner is required.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to preferred embodiments. [Embodiment 1] FIG. 1 is a partially cutaway plan view of this embodiment.
FIG. 2 is a partially cutaway side view.

In the figure, (7) is a main body of the cleaning machine, which is provided with an electric pump (3), a motor (10) for driving the electric pump (3), and a battery (11).

Reference numeral (1a) is a suction nozzle, which is connected to the main body (7) through a handle (6) protruding from the main body (7). The suction nozzle (1a) is attached to the handle (6) at a substantially right angle.

The handle portion (6) may be rod-shaped or pipe-shaped as shown in the drawing, but if a flexible synthetic resin plate or metal plate is used, the suction nozzle can be used by utilizing the bending of the portion. It becomes easy to bring (1a) into close contact with the cleaning surface (19).

Reference numeral (2a) is a sponge portion as a water absorber attached to the contact portion of the suction nozzle (1a) with the cleaning surface, and has a large number of continuous bubbles. The water absorbent body (2a) may be a sheet material having a large number of communication holes other than a sponge. As a material constituting the water absorber (2a), a hydrophilic group (OH group, CO
Resins having OH groups, silanol groups, amino groups, sulfone groups, etc.) are preferred.

When a sponge-like sheet is used as the water absorbent (2a), it is preferable to use, as the material of the sponge portion, a material having hydrophilicity and a large primary water absorption as described above, such as polyurethane or polyvinyl. An open cell foam obtained by foaming an alcohol formalized resin is suitable.

Such a foam is used for the cleaning surface (1
The water (20) of 9) is taken up inside the sponge and is primarily adsorbed on the hydrophilic group with little or little volume expansion, and then the continuous bubbles of the sponge are immediately generated by the suction force of the pump (3). This is because continuous suction and drainage from the through hole (4) is performed. That is, since the hydrophilic groups are exposed on the surface of the open cells, when they come into contact with water, the hydrophilic groups instantly adsorb the water, and by the capillary phenomenon reinforced by the hydrophilic groups existing in the entire foam. Moisture that has been adsorbed momentarily diffuses throughout the sponge, removing the water (20) on the cleaning surface (19). The water diffused throughout the sponge is only temporarily adsorbed by the hydrophilic groups, so the pump
Due to the suction force of (3), the sponge is sucked and discharged one after another from the through hole (4) and the sponge itself does not saturate, and it is possible to keep a certain equilibrium state and effectively continue to absorb the water on the cleaning surface (19). Like

On the other hand, it is not preferable to use a sponge having poor water absorption since it has no hydrophilic group and primary water absorption is not good, so that only the portion sucked by the electric pump (3) absorbs water and the water absorbing effect is reduced. In the case of the above-mentioned sheet material having the communication holes, the water is effectively absorbed by the action of the hydrophilic group exposed in the communication holes as in the case of the sponge.

Reference numeral (14) is a hollow portion provided over substantially the entire length in the suction nozzle (1a), which communicates with the hose connecting portion (15) and also has a thin through hole () extending to the sponge portion (2a). It also communicates with 4). Position, number, and number of through holes (4) that contact the sponge part (2a)
The size depends on the shape and thickness of the sponge part (2a), the electric pump
Although it may be appropriately determined according to the suction force of (3) and the like, in this embodiment, the sponge portions are arranged in a line at substantially equal intervals so as to come into contact with the back side of the portion in contact with the cleaning surface.

FIG. 8 is a sectional view of the main body (7) in the vicinity of the electric pump (3). A bellows pressing body (49) is attached to the shaft (5) of the motor (10). The pump has a plurality of bellows parts (41) and (42), and the bellows pressing body (49) rotates while sequentially pressing and releasing each bellows part by the rotation of the motor (10). This type of pump is more durable against dust than piston pumps and rotary pumps,
It also has the feature that it operates even if you do not receive water.

Since the air and water in the bellows part (42) cannot return by the valve body (40), the bellows pressing body (49) presses the bellows end (46) away from the pump base (33) and the bellows outlet. (44) communicates with the drain (47). Then, the air and water in the bellows part (42) pass through the drain groove (47) and the suction / drain port (3
It is led to the drain port (32) provided in (0).

Also, the bellows portion (41) released by pressing
The bellows end (45) comes into contact with the pump base (33) to close the bellows outlet (43) and the valve disc (39 ) Opens.
Then, water or air from the water intake port (31) is guided into the bellows part (41) through the water absorption grooves (36) (37).

The pressing of the bellows portions (41) and (42)
By repeating the opening, water and air can be continuously sucked in through the water intake port (31), and water and air can be discharged through the drainage port (32).

The water suction port (30) is connected to the hose connection portion (15) of the suction nozzle (1a) via the water suction hose (8). Further, the drain port (32) is connected to the drain pipe (9). In the case of car washing in the open field, nothing should be connected to the drain pipe (9) and water should be drip from the end of the drain pipe (9) to the ground,
When it is not possible to wet the floor as in the case of indoor use, a drain tank can be attached to the end of the drain pipe (9) for use.

In use, the electric pump (3) is operated to bring the suction nozzle (1a) into contact with the cleaning surface (19). Cleaning surface

Sucked by.

The water suction pipe (8) by the operation of the electric pump (3)
The hollow portion (14) in the suction nozzle (1a) communicating with is in a reduced pressure state. Therefore, the water sucked by the sponge part (2a) is drawn into the cavity part (14) through the through hole (4).

Cleaning surface of the sponge part (2a) as in this embodiment
When the through hole (4) is provided only on the back side (lower part) of the part that comes into contact with (19), as shown in FIG.
The water that has been primarily absorbed into a wide area of (2a) is drawn into the cavity (14) only from the lower through hole (4). If a through hole (4) is provided in the side part, a cavity is also formed from the through hole (4) in the side part as shown in FIG. 9 (b).
It is drawn into (14).

The water drawn into the cavity (14) is drained from the drainage pipe (9) through the water absorption pipe (8) and the electric pump (3).

Since the sponge part (2a) containing water has pores communicating with each other, the water in the sponge part (2a) moves through the communication holes and is drawn into the pores (4). . Therefore, the amount of water retained by the sponge part (2a) can be continuously used without reaching the limit of retention (without water saturation).

Also, water droplets sucked into the sponge part (2a)
Dust and the like contained in (20) are also discharged together with water from the drainage pipe (9) and are unlikely to accumulate in the sponge part (2a), so that the cleaning surface will not be damaged even if it is used continuously.

When the sponge part is worn, it may be replaced, in which case only the sponge part (2a) may be replaced, or the hollow part (14) and the pores (4) may be replaced.
It may be replaceable as a unit having a sponge part (2a).

[Embodiment 2] FIG. 3 is a partially cutaway side view of this embodiment. The main body (7) side is the same as that of the first embodiment, but the suction nozzle (1b) is different from that of the first embodiment (1a).

The suction nozzle (1b) can be rotated within a certain range about a shaft (12) provided near the tip of the nozzle of the handle (6). Therefore, even if the cleaning surface (19) is a curved surface, the sponge portion (2b) of the suction nozzle (1b) can be brought into contact with the cleaning surface (19) without difficulty.

The tip of the sponge portion (2b) is provided with a rubber latch (5). When the suction nozzle (1b) moves on the cleaning surface (19), the rubber scraper scrapes the water droplets (20) on the cleaning surface (19) like a car wiper, so the water droplets can be sponged more efficiently. It can be absorbed in part (2b).

This embodiment has the same basic structure as that of the first embodiment, but is provided with a direction switching valve (60) capable of switching between water absorption and drainage of the electric pump (3). (61) is a switching lever of the directional control valve (60).

Therefore, in normal use, the same action and effect as those of the first embodiment can be obtained. Then, move the switching lever (61) of the direction switching valve (60) to move the electric pump.
When the suction / drainage direction of (3) is reversed, water flows backward and the water in the drainage tank (62) is sent to the suction nozzle (1) through the electric pump (3).

The water sent to the suction nozzle (1) is once held in the sponge part (2a), but when water is sent one after another, it cannot be held in the sponge part (2a) (water is saturated).
The foam is discharged from the sponge part (2a).

As a method of using this embodiment, fresh washing water is put in the drain tank (62) in advance and the direction switching valve (60) is used.
