Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable washing device which is used for washing a human body part and is generally called a portable bidet or a portable washlet.

[0002]

2. Description of the Related Art A washing machine for washing a human body part is widely used in order to raise awareness of health and to keep cleanliness. The washer is usually installed on a toilet seat, and a nozzle protruding from the body of the washer swings back and forth, left and right while spraying washing water to the user to wash the local area. Tap water is used as the cleaning water, and the cleaning water is supplied directly to the main body.

A variety of portable cleaners have been proposed in response to a desire to use such a cleaner even when out of the office. These portable washer includes a main body containing a pump and a battery, a tank for storing cleaning water, and a nozzle that is locked to a part of the main body. The stored cleaning water is ejected from the nozzle by a pump using a battery as a power source to clean the local area. In the case of a portable cleaner having such a configuration, in order to obtain a cleaning feeling equivalent to that of a stationary cleaner, 6 to 8 cc / s of cleaning water is used.
It is necessary to eject from the nozzle portion in an amount of ec and continue this for 30 seconds. In order to meet such usage conditions, it is necessary to set the capacity of the tank portion to about 200 cc, but a structure in which the main body portion and the tank portion are simply integrated requires a very large housing, which makes it portable. Is unsuitable as

Therefore, a detachable structure is conceivable in which the tank portion is formed into a cylindrical container having a bottom, and one end of the tank portion is screwed or engaged with the main body portion during use. With this structure, since the main body portion can be housed in the tank portion when being carried, portability is not impaired. However, there is a problem that it takes time to assemble and disassemble before and after use, resulting in poor usability.

In order to solve this problem, the body part and the tank part are slidably connected, and the body part is fitted into the tank part when carrying, so that the volume when carrying can be reduced. Is being developed. FIG. 11 shows a prior art example of a portable cleaning device which adopts a structure in which the main body part can be put into and taken out of the tank part. Sometimes, the main body 31 can be stored in the wash water storage space, and the main body 3 is rotated when carrying the main body 3.
1 and the nozzle part 33 which can be accommodated. The shapes of the main body 31 and the tank 32 are elliptical in transverse cross section so that the direction of the ejection holes 35 of the nozzle 33 can be grasped only by the tactile sensation by hand when used. Further, a switch 34 is provided in a portion of the main body 31 formed in an elliptical shape substantially parallel to the direction of the major axis of the elliptical shape, and the switch 34 is used in an upward direction so that the ejection hole 35 of the nozzle portion 33 is raised. Is configured to face. Therefore, at the time of use, the switch 34 can be pressed with the thumb and grasped, the nozzle portion 33 is inserted into the crotch so as to be located locally below, and when the switch 34 is pushed, the cleaning water is ejected from the ejection hole 35 and ejects the cleaning water. This makes it possible to clean the local area.

In the above structure, since the nozzle portion 33 can be housed in the main body portion 31 when carrying, and most of the main body portion 31 can be housed in the tank portion 32, the volume when carrying is small. At the time of use, as shown in the drawing, the main body 31 is pulled out from the tank 32 and the nozzle 33 is started up. To store the wash water in the tank portion 32, the tank portion 3 formed in an elliptical shape is used.
It is only necessary to inject water from the water supply port 36 provided in a portion of the elliptical shape 2 that is substantially parallel to the major axis direction, and it is possible to secure the wash water injection necessary for washing in a full state.

[0007]

However, in the tank portion 32 having the above-mentioned structure, as shown in FIG.
Since the water supply port 36 is provided at a site substantially parallel to the major axis direction of the ellipse, when the main body portion 31 is advanced into the tank portion 32 for carrying, the main body portion 31 is connected to the tank portion 32. The packing 48 provided in the portion is the water supply port 36.
It will be exposed to the outside through the opening. Packing 48
Is made of a rubber-like member that is pressed against the inner wall of the tank portion 32 to maintain a watertight structure, and therefore, if a part of the member is exposed from the opening from the state where it is pressed against the smooth inner wall of the tank portion 32, it is elastic. The packing 48, which is a material, swells to the outside without pressing the wall surface against which pressure is applied, and is subjected to sliding in this state, and if this is repeated, the packing 48 will be greatly worn and scratched, and the space between the main body 31 and the tank 32 will be increased. The watertight structure of the water will be impaired and washing water will leak. Therefore, the advance of the main body 31 into the tank 32 needs to be stopped before the water supply port 36. As a result, the amount of the main body 31 accommodated in the tank 32 is reduced, so that the main body 31 can be easily transported. The volume cannot be reduced.

Therefore, if the water supply section 36 is provided at the bottom of the tank section 32 formed in the bottomed cylindrical body, the main body section 31 can advance to the full space in the tank section 32, and the volume when carrying is reduced. Can be made. However, in this structure, it is required that there is a space for the length of the tank portion 32 and the main body portion 31 under the water faucet at the time of water supply. Such portable washer is for use on the go,
You can only get limited tap water, and most will get water from the washbasin or hand-washing tap in the toilet. The faucet in such a place has a small gap between the faucet tip and the wash basin, etc., and it is often impossible to make the washer upright with the water supply port provided at the bottom facing up.
Since the washing device is tilted and water is injected from the water supply port, not only is it difficult to inject water, but water leaking from the water supply port may wet the entire cleaning device.

As described above, there is a problem whether the water supply port is provided on the bottom portion or the side surface of the tank portion.

An object of the present invention is to increase the amount of the main body accommodated in the tank portion when it is carried, and to provide a portable washer equipped with a tank portion structure that facilitates water supply to the tank portion during use. To provide.

[0011]

According to the present invention, there is provided a main body portion for accommodating a pump, a tank portion having a space for storing cleaning water and slidably fitted in the main body portion, and the main body portion or A nozzle portion that is attached to the side of the nozzle so as to be stowable and has a plurality of ejection holes for ejecting the cleaning water at the tip,
In a portable cleaning device that sucks up the cleaning water stored in the tank portion by the pump and ejects it from the ejection hole,
The tank portion is formed as a bottomed cylindrical body with one side open, and an opening for water supply is formed at the bottom thereof, and a water supply lid for opening and closing the opening is pivotally supported on the bottom, and the inner surface thereof is A gutter that guides the wash water flowing down from above when opening the lid is formed to project, and an O-ring is provided at the base of the gutter.
Then, when the water supply lid is closed, the O-ring is located inside the opening.
It is characterized in that it is configured to be pressed against .

According to the above structure, since the water supply opening for supplying the wash water into the tank is provided at the bottom of the tank, it is possible to increase the amount of the main body accommodated in the tank when being carried. Therefore, it is possible to improve the portability by reducing the volume when carrying. In addition, the gutter provided on the inner surface of the water supply lid directs the flow of the water supply toward the opening when the water supply lid is opened, so it can be washed when the space between the faucet and the wash basin at the bottom is small. Even when the vessel is tilted, the gutter guides the wash water flowing down from above into the tank,
Water can be poured easily.

When the water supply lid is locked at a predetermined opening angle, if the gutter is directed toward the opening, water can be poured easily by locking the water supply lid at a predetermined angle and supplying water. You can

Further, it is possible to construct a rectifying plate for preventing water splashing inside the gutter, and it is possible to prevent the washing machine from getting wet due to the scattering of the washing water flowing down.

Is in contact with the storage space. When the nozzle part 3 is rotated to be housed in the main body part 1 from the use state shown in FIG. 2 and the main body part 1 is inserted into the tank part 2, the volume becomes small as shown in FIG. It can be made into a compact form.

When used, the main body 1 is pulled out from the tank portion 2, the water supply lid 17 of the tank portion 2 is opened to inject the washing water into the tank portion 2, and the water supply lid 17 is carried as shown in FIG. , The nozzle part 3 is raised from the main body part 1, and the switch 5 is pressed, the cleaning water in the tank part 2 is sucked by the pump 7 by the rotation of the motor 6, and is sent to the nozzle part 3 from the drain pipe 11. It spouts from the spout hole 10. For cleaning, as shown in FIG. 4, it is possible to hold the main body 1 and the tank 2 with the hand and hold the switch 5 with the thumb. Therefore, as shown in FIG. By pressing the switch 5 with the hole 10 directed to the local area, the cleaning water can be applied to the local area. Since the cleaning device is held by hand, the position where the cleaning water is applied can be freely changed.

As the washing progresses, the amount of washing water in the tank portion 2 decreases, but at the bottom of the tank portion 2 in order to maintain ventilation between the inside of the tank portion 2 which is a closed space and the outside. An air valve 12 is provided. The air valve 12 discharges the air in the tank portion 2 to the outside even when the main body portion 1 enters the tank portion 2 in order to bring the main body portion 1 into the tank portion 2 of the main body portion 1. It works so that it can be stored smoothly.

As the cleaning water stored in the tank portion 2, tap water is usually used, but when going out, the cleaning water is obtained from a tap in a limited place, and most of them are washrooms. And from the hand-washing faucet. When storing the wash water in the tank 2 from such a tap, there is a water receiver such as a washbasin 27 under the faucet 26 as shown in FIG. In many cases, it cannot be placed in the upright position. Therefore, the portable washer A is inclined and the water supply port is located below the faucet 26,
Water will be supplied to the tank section 2. A water supply structure is formed on the bottom surface of the tank portion 2 so that the wash water can be easily stored in the tank portion 2 even in such a state.

FIG. 7 is a perspective view showing the water supply structure. A water supply lid 17 for opening and closing the opening 14 for water injection is rotatably supported by a base 39 provided on the bottom surface of the tank 2. The rotating arm 4 rotatably supported by the base 39 from the closed state of the opening 14 to the fully opened state shown in FIG.
It rotates by using 9, 49 as a rotation fulcrum. Also, the water supply lid 17
Can lock its open angle at a predetermined angle position. When the washing device can be placed upright under the water faucet, the water supply lid 17 is fully opened and the water injection opening 1 is provided.
Although water can be poured into the tank portion 2 from 4, when the space under the faucet 26 is not sufficient and the washing device can be arranged only in a tilted state, as in the case shown in FIG. 6,
The opening angle of the water supply lid 17 is locked at the angle shown in FIG. At this time, the gutter 13 provided on the inner surface side of the water supply lid 17
Is directed to the inside of the tank portion 2, receives tap water flowing down from the direction of the arrow in the drawing, and changes the flow direction so as to be directed to the inside of the tank portion 2. As shown in FIG. 7, the water-splash-preventing rectifying plates 28 are arranged in a row inside the gutter 13,
There is no chance that the entire washing device will get wet due to splashing of water, and a smooth flow of water can be formed by the straightening vanes 28 aligned toward the inside of the tank portion 2. By the water injection through the gutter 13, even when the water can be supplied only when the cleaning device is tilted, it is possible to easily supply the cleaning water, and the water can be supplied until the tank portion 2 is almost full.

To lock the water supply lid 17 at the open angle, the projection of the engaging piece 38 formed on the base of the water supply lid 17 is fitted into the locking hole 40 provided in the base 39 that pivotally supports the water supply lid 17. By arranging a plurality of locking holes 40 for each rotation angle, the water supply lid 17 can be locked at a plurality of opening angles. In addition, the O-ring 2 is provided on the base of the gutter 13 of the water supply lid 17.
9 is inserted. When the water supply lid 17 is closed, O
The ring 29 is brought into pressure contact with the inner peripheral portion of the opening 14 and the tank portion 2
Prevent leakage of wash water stored inside.

The remaining amount of the cleaning water stored in the tank portion 2 due to the water supply can be visually confirmed by forming the tank casing 2a with a transparent or translucent material. The cleaning water stored in the tank portion 2 is sucked by the pump 7 from the suction port 8 shown in FIG.

As shown in FIG. 2, the nozzle portion 3 of the portable cleaner A according to this embodiment has a tubular portion 15 and a sliding portion 16 as shown in FIG.
Are provided, and the sliding portion 16 moves to the tip side of the nozzle portion 3 on the tubular portion 15 and the "strong" position.
It is possible to select a “weak” position that is moved from the position to the main body 1 side. At the tip of the tubular portion 15, 2 from the tip side
The five ejection holes 10 formed in three rows of one, one, and two are provided on the main body 1 side when the sliding portion 16 is moved to the tip side to the “strong” position. Spout hole 10 is closed 3
Cleaning water is ejected from the individual ejection holes 10. The washing water sent at the same pressure from the pump 7 has a small number of ejection holes 1
By ejecting from 0, the ejection pressure is increased, resulting in a strong ejection and a state suitable as a washlet for washing the anus and its surroundings after the toilet is obtained.

On the other hand, when the sliding portion 16 is moved to the main body 1 side and is in the "weak" position, the washing water is jetted from all five jet holes 10, so that the pump 7 sends the washing water at the same pressure. When the washing water is jetted from the jet holes 10 in a larger number than at the “strong” position, the jet pressure is lowered, and the jet water becomes a weak jet so that a soft jet state suitable for use as a bidet can be obtained.

The jet pressure switching structure by the sliding portion 16 is constructed as shown in FIG. 9, and the sliding portion 16 and the tubular portion 15 constitute jet hole switching means.

As shown in FIG. 2, the nozzle portion 3 is constructed by connecting a tip portion 3a to a rotating portion 3b which is rotatably supported by the body portion 1, and the tip portion 3a is As shown in the side view from the tip side of FIG. 9A and the exploded view of FIG. 9B, the sliding portion 16 is fitted to the tubular portion 15.

The sliding portion 16 has four fitting portions 19a to 19a.
9d (19d is on the opposite side symmetrical position of 19b) fitting grooves 18a to 18d (18c, 1c formed on the cylindrical portion 15).
8d is located on the opposite side symmetrical position of 18a and 18b), and the protrusion 21 shown in FIG. 9 (d) is fitted into the sliding groove 20 of the tubular portion 15 shown in FIG. 9 (c) in the longitudinal direction. It is configured to be slidable on. The sliding width of the sliding portion 16 is
As shown in FIG. 9C, the left and right sides 2 formed in the tubular portion 15
In each of the concave portions 22a to 22d, one convex portion 23 on each of the left and right sides is formed on the sliding portion 16 as shown in FIG. 9D.
It is regulated by fitting a and 23b together. As shown in FIG. 9D, a seal member 24 made of silicon rubber and formed in a T shape is attached to the inner side of the sliding portion 16 on the front end side. When moved dynamically, the seal member 24 closes the two ejection holes 10c on the main body 1 side. Since the ejection hole 10c is formed on the raised portion 42 which is slightly higher than the other ejection holes 10a and 10b, the sealing member 24 presses the opening and seals. Therefore, the sliding portion 16 grips and slides the anti-slip portions 25 formed on both sides of the outer surface of the sliding portion 16, so that all five jets are ejected when the ejection holes 10c are opened as shown in FIG. 10 (a). Since it is jetted from the holes 10a to 10c, it can be used as a bidet that can be softly washed with a weak jet pressure. As shown in FIG.
When 0c is blocked by the sliding part 16, the cleaning water is
Since it ejects from the individual ejection holes 10a and 10b, it can be used as a washlet with which a strong ejection pressure can be obtained.

The cleaning water supplied to the nozzle portion 3 having the above structure is sucked by the pump 7 from the suction port 8 shown in FIG. 2. The position of this suction port 8 is the injection port of the nozzle portion 3 during use. When the tank 10 is held in a tilted position with the tank portion 2 facing upward, since the position is the lowest end in the tank portion 2, the stored cleaning water can be supplied to the pump 7 without waste. Further, since the tank portion 2 is formed into an elliptic cylindrical shape, the suction port 8 is located at the lower end portion of the narrow surface of the elliptical shape, so that the width in the horizontal direction is small. Even when compared to the configuration in which the wide surface is the bottom and the horizontal width is large as described above, the amount of wash water that remains without being sucked to the end is small.

By forming the tank portion 2 and the main body portion 1 in the elliptical shape as described above, not only can the washing water stored in the tank portion 2 be used without waste, but also from the washing water nozzle portion 3. It is also possible to easily perform the operation of changing the ejection direction of the. That is, it is difficult to visually confirm the spouting of the washing water, but as shown in FIGS. 4 and 5, the switch 5 on the upper side of the elliptical shape is pressed with the thumb, and the other four fingers are pressed downward. The entire washer can be rolled simply by supporting the narrow surface on the side and moving the finger, and the direction of jetting of the washer can be easily changed even in an inconvenient posture with the washer positioned in the crotch.

[0033]

As described above, according to the present invention, since the water supply opening for supplying the wash water into the tank portion is provided at the bottom of the tank portion, the storage amount for accommodating the main body portion inside the tank portion when carrying the tank portion. Can be increased, and the volume when carried can be reduced to improve portability. In addition, since the gutter provided on the inner surface side of the water supply lid guides tap water flowing down from above into the tank part, water can be injected smoothly even if the entire washer is slanted. Water can be easily supplied to the tank even in a place where there is not enough space.
