[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric bathtub cleaning apparatus capable of efficiently cleaning not only general domestic bathtubs but also large commercial bathtubs with light labor efficiently. is there.

[0002]

2. Description of the Related Art Conventionally, when cleaning a bathtub in a general household, a brush or a sponge for cleaning is used to manually wash the bathtub. You have to do a lot of hard work because you have to scrub the surface of. Therefore,
In recent years, an electric bathtub cleaning device (for example, see Utility Model Registration No. 3032566) has been devised that can quickly clean the bathtub surface by an easy work that can reduce the labor of the operator.

As shown in FIG. 7, the bath cleaning device is
A casing 1 having a grippable handle 1a, an operation source motor 2 and a speed reduction mechanism 5 housed in the casing 1, a long pipe 3 attached to a tip end side of the casing 1, and a speed reduction mechanism 5. The rotary shaft 4 connected to the drive shaft 6 and inserted through the pipe 3 and the cleaning brush 7 made of synthetic resin attached to the tip of the rotary shaft 4 are main components. The casing 1 has a power cord wire 8 for connecting to a commercial AC power source, and a motor 2
A switch 9 for turning on / off the power supply to the power source is provided. In addition, an auxiliary handle 1 is provided in the middle of the pipe 3.
0 is provided.

In this bathtub cleaning device, a plug (not shown) of the power cord 8 is connected to a commercial AC power source, and then the handle 1a of the casing 1 is held by one hand and the auxiliary handle 10 is held by the other hand. When the operator holds the device by holding the switch and turns on the switch 9 with a finger, the rotation of the motor 2 is transmitted to the cleaning brush 7 via the speed reduction mechanism 5 and the rotating shaft 4. The worker cleans the bath surface while bringing the rotating cleaning brush 7 into contact with the surface of the bath to which the detergent is applied.

[0005]

DISCLOSURE OF INVENTION Problems to be Solved by the Invention
Since the cleaning brush 7 that rotates electrically is provided at the tip of the long pipe 3, the bathtub can be cleaned in a comfortable posture without bending the waist, so that it can be used manually with a brush or sponge. In comparison, the labor of cleaning work can be significantly reduced. However, in the bath cleaning device, since the relatively heavy components such as the power supply device including the transformer, the motor 1 and the speed reduction mechanism 5 are all housed in the casing 1, the overall weight balance is extremely poor. Therefore, in the cleaning operation using the cleaning device, the cleaning brush 7 at the tip of the pipe 3 is brought into contact with the surface of the bath while gripping the heavy casing 1,
It has a drawback that it is not easy to use and it is difficult to operate the cleaning brush 7 as intended.

Further, since the long pipe 3 has a relatively large diameter into which the rotary shaft 4 can be inserted, the presence of the large pipe 3 and the rotary shaft 4 makes it possible. The entire weight of the lower end side of the casing 1 becomes larger, and the auxiliary brush 10 is gripped and the cleaning brush 7
It is necessary to operate the abutting point of the, and the workability is further deteriorated from this point as well.

Further, the bath cleaning device is adapted to obtain driving power from a commercial AC power source through the plug of the power cord line 8. However, since a power outlet is not generally provided inside the bathroom, the bath outside the bathroom is not provided. It is necessary to insert the plug into the outlet and pull the power cord wire 8 into the bathroom, which also makes the workability worse.

Therefore, it is conceivable that the secondary battery as a driving power source is housed in the casing 1 instead of the commercial AC power source. In such a configuration, the secondary battery is charged. At this time, the entire bath cleaning device must be taken out of the bathroom and connected to the charger, which is awkward to handle. On the other hand, when a charger having a power cord connected to an outlet outside the bathroom is brought into the bathroom to charge the secondary battery, water may be splashed on the cleaning device and the charger during charging.

Therefore, the present invention has been made in view of the above-mentioned conventional problems, and the workability is remarkably improved by reducing the weight of the entire apparatus and setting the weight balance such that the center of gravity exists in the substantially central portion of the entire apparatus. It is an object of the present invention to provide an electric bath cleaning device that can be improved.

[0010]

To achieve the above object, according to the Invention The electric bathtub cleaning apparatus of the present invention has a graspable outer, a handle case battery is accommodated therein, the
An intermediate case detachably connected to the lower end of the handle case.
A long handle pipe connected to the lower end of the intermediate case, and a motor case fixed to the lower end of the handle pipe, in which the motor of the operation source and the speed reduction mechanism are housed,
A cleaning brush attached to the drive shaft of the speed reduction mechanism and rotating, and the handle case is attached to the intermediate case.
When they are connected or attached to the charger.
Contact with the connection plug that makes electrical contact by touching
It has either one of the toreed part and the handle case.
When connected to the intermediate case, it is provided on one side of these.
Connecting plug and the contact on the other side
The motor is configured to be supplied with drive power from the storage battery through a power cord wire inserted in the handle pipe by connecting to the toreed portion .

In this electric bath cleaning apparatus, the storage battery as a heavy object is housed in the handle case on the upper end side, and the motor and the speed reduction mechanism as the heavy object are housed in the motor case on the lower end side, respectively. The weight balance is good as a whole, and the center of gravity of the entire apparatus can be set at the substantially central portion in the longitudinal direction. Moreover, compared to the conventional device, no rotating shaft is required,
As a result, a shaft having a small diameter can be used, so that the overall weight can be reduced. Therefore, the bathtub cleaning device is remarkably improved in usability, and the surface of the bathtub can be cleaned very efficiently and efficiently with good workability.

[0012]

Further , according to the present invention, when charging the storage battery, only the handle case accommodating the storage battery is removed, and the handle case is attached to a charger installed at an arbitrary location outside the bathroom. This makes it possible to carry out the bathtub cleaning device as a whole outside the bathroom, or to carry out the charging by bringing the charger into the bathroom for charging, and to clean the corridor outside the bathroom or the room or bathtub. There is no problem such that the device itself gets wet with water.

In the electric bath cleaning apparatus of the present invention, it is preferable that both ends of the handle pipe are fitted in the intermediate case and the motor case, respectively, and liquid-tightly bonded and fixed with an adhesive. As a result, the intermediate case and the motor case can be remarkably slimmer in shape, as compared with the case where they are liquid-tightly fixed using an existing seal member such as an O-ring.

Further, in the electric bath cleaning apparatus according to the present invention, the drainage penetrating to the outside is provided below the portion of the intermediate case where the connection plug portion and the contact lead portion come into electrical contact with the handle case. It is preferable that the holes are formed.

Thus, if water has penetrated into the intermediate case from the upper end opening of the intermediate case for some reason before the handle case is attached, the penetrated water passes through the drain hole of the intermediate case to the intermediate case. Since it is discharged to the outside of the case, it is possible to reliably prevent the pair of contact lead portions or the pair of connection plug portions from being electrically short-circuited with each other.

Furthermore, in the electric bath cleaning apparatus of the above invention, the upper end opening of the handle case is covered with a lid fixed by a screw, and is attached to the upper end portion of the battery case provided in the handle case. And a rubber cap that is bulged and deformed in the direction in which the outer diameter increases when the gas pressure inside the battery case rises to a predetermined value, and the rubber cap that is formed below the screw head of the screw and bulged and deformed It is preferable that the degassing mechanism is configured by the small recesses that discharge the gas that has passed through the clearance between the screw and the screw hole after being discharged from the clearance.

As a result, when the gas generated by overcharging or overdischarging from the storage battery liquid-tightly accommodated in the handle case of the bathtub cleaning device is filled in the battery case, this gas pressure is set. When the rubber cap has risen to a predetermined value, the rubber cap is bulged and deformed by receiving the gas pressure. Gas is
After the rubber cap is discharged from the battery case through the gap generated in the rubber cap due to the bulging deformation between the rubber cap and the cap mounting cylinder part to which it is attached, the screw for fixing the lid and this screw It is discharged to the outside through a gap with the existing screw hole and further through a small recess provided below the screw head of the screw. Therefore, in this bath cleaning apparatus, it is possible to reliably prevent the occurrence of problems such as swelling and destruction of the apparatus due to the gas being filled inside.
