DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a sanitary washing device.

[0002]

2. Description of the Related Art Conventionally, many hand-held sanitary washing machines have been considered as disclosed in Japanese Patent Application Laid-Open No. 9-289957. Such a hand-held sanitary washer is very useful not only for general use but also for those who need care. However, when using such a sanitary washer for those in need of care,
A problem arises in that the sewage of the caregiver is splashed during cleaning.
For this reason, it has been considered to provide a scattering prevention guide as shown in Registered Utility Model Publication No. 3040163, but this is used in general toilets and is used for caregivers. There were still problems to solve.

[0003]

First, when cleaning a local part of a cared person, a cleaning operation on a bed is supposed, so that the amount of scattered sewage must be reduced as much as possible. For this purpose, it is effective to make the splash prevention guide abut the buttocks, but if the washing work is performed with the splash prevention guide still in contact with the buttocks, the spray direction of the cleaning liquid cannot be changed, and the There is a problem that cleaning cannot be performed. In other words, in the case of such a conventional example, since the scattering prevention guide is used away from the buttocks for washing around the local area, the scattering cannot be sufficiently prevented when used for a cared person. .

[0004]

An object of the present invention is to provide a sanitary washing machine which can solve the above-mentioned problems.

[0005]

In order to solve the above-mentioned problems, according to the first aspect of the present invention, a nozzle portion for ejecting a liquid is supported so as to swing freely, and a front end side is at least forward of a front end of the nozzle portion. And a tip end side of the scattering prevention part can be freely contacted with the part to be cleaned. Therefore, the nozzle part can swing freely while the scattering prevention part is in contact with the to-be-cleaned part such as the buttocks, so that it is possible to freely direct the nozzle tip to the vicinity of the local part while sufficiently maintaining the scattering prevention effect. In addition, since the tip end side of the scattering prevention portion is supported in contact with the portion to be cleaned, the position of the scattering prevention portion is stabilized during cleaning, and a good nozzle swing operation can be performed using the scattering prevention portion as a fixed portion. According to the second aspect of the present invention, since the scatter prevention unit is made detachable, there is an effect that replacement of the scatter prevention unit becomes smooth. In the invention according to claim 3,
The distal end side of the scattering prevention portion has a curved surface, so that the contact with the portion to be cleaned is soft. Further, when a soft material is disposed on the distal side as in claim 4, the contacting force is reduced and the portion to be cleaned is removed. And the adhesion to the substrate can be improved. The invention according to claims 5 and 6 has an effect that the cleaning liquid accumulated in the scattering prevention portion can be discharged smoothly.

Further, on both sides of the pump P, as shown in FIG. 3, a storage battery B for supplying power to the pump P and a charging section C for charging the storage battery B are provided, respectively. A power supply port D to the heater H and the storage battery B is provided at a lower portion of the peripheral surface of the power supply 1 (see FIG. 3).

Reference numeral 8 denotes a power supply cord. One end of the power supply cord has a magnet plug 80 detachably attached to the power supply port D, and the other end has a plug 81 corresponding to a household outlet (not shown) serving as an AC power supply. ing.

The operating section 7 of the sanitary washer A is shown in FIG.
As shown in FIG. 3, a bulging portion 13 bulging outward is formed on a side of the main body 10 facing the pivot portion.
Is provided on the upper surface.

That is, an operation switch 71 for driving / stopping the pump P and a display lamp for lighting when the pump is driven are provided on the left side of the recess 13a formed at the center position of the bulging portion 13, and on the right side of the recess 13a. A temperature setting switch 73 capable of setting the washing water temperature in three stages of low, medium and high, an on / off indication lamp of the heater H, and a washing water temperature indication lamp are provided. Reference numeral 76 denotes a lock release button for the lid 6.

In this embodiment, the temperature setting switch 7
3 is a push type, and the number of pushes is set to low temperature, medium temperature, and high temperature, but the switch structure is not particularly limited.

Here, the electric circuit of the sanitary washer A is shown in FIG.
The input terminal D1 connected to the storage battery B and the heater H is provided at the power supply port D, and the drive motor M of the pump P, the storage battery B, and the operation switch 71 are connected in series. Operation of pump P by operation of 71
Stopping is performed.

The primary side of the transformer T provided in the charging section C is connected to the input terminal D1, and the same primary side is connected to the heater H.
And the secondary side of the transformer T is dropped to a predetermined charging voltage of the storage battery B, so that the diode rectifier 7

With this configuration, when the magnet plug 80 of the power cord 8 is inserted into the power supply port D and the plug 81 is inserted into the outlet, the heater H and the storage battery B are energized, the washing water is heated to an appropriate temperature, and the storage B , A charging current flows, and the heater H can be heated and charged at the same time.

Therefore, the sanitary washer A can be used by the power of the storage battery B even when there is no outlet at the place where the sanitary washer is used.

The washing apparatus A includes a pump control unit E as control means for prohibiting the operation of the pump P when the temperature of the washing water rises to a certain value or more. And an open / close switch 78 provided in the circuit of the drive motor M of the pump P are electrically connected.

That is, when the abnormal temperature detecting sensor S3 detects the temperature of the washing water exceeding the temperature control range of the temperature sensors S1 and S2, the pump controller E turns off the open / close switch 78 based on the detected value. The driving of the pump P is prohibited, thereby preventing the hot water or the like from being spouted from the nozzle unit 4 by mistake. Therefore, for example, when the hot water having a temperature exceeding a certain value is used, for example, when the hot water is boiled externally and directly put into the water storage unit 10, the pump P is not driven even when the operation switch 71 is turned on. There is no danger of hot water spurting and causing burns.

Alternatively, the temperature sensors S1, S2
Even if the water temperature rises significantly for some reason, the abnormal temperature detection sensor S3 detects this and outputs a detection signal to the pump control device E, so that the pump P is not driven, so that it is safe.

In this embodiment, the pump control device E is provided in the circuit of the heater H, and the operation of the pump P is prohibited while the heater H is energized.

Therefore, when power is supplied from the AC power source, that is, when the storage battery B is being charged while the washing water is being heated, the pump P is not driven, so that an electric shock accident or the like can be prevented beforehand.

Next, the cleaning section 2 will be described.

The washing section 2 is constituted by connecting and connecting the pump P of the main body 1 and the nozzle section 4 through a hose 5.
As shown in FIG. 4, the nozzle portion 4 is formed in a pistol shape having a grip portion 40, a cleaning water passage R is formed therein, and a valve hole 42 is formed in the cleaning water passage R. A valve body 43 which can be freely attached and detached is provided in the valve hole 42,
The valve body 43 is urged in the valve closing direction by a spring 41 to form the on-off valve J.

A trigger lever 44 for operating the valve body 43 in the valve opening direction is connected to the nozzle portion 4. 44
“a” is a mounting shaft of the lever 44.

As shown in FIGS. 4 and 5, the nozzle portion 4 is provided with a transparent scattering preventing portion 100 made of a water-repellent material such as a crystalline resin such as polyethylene or nylon. The scattering prevention unit 100 is formed in a substantially cup shape, and a cushioning material 101 made of a soft material such as rubber is attached to the distal end side over the entire circumference. A circular hole 102 is formed in the center of the scattering prevention portion 100, and the circular hole 102 is large enough to allow the nozzle portion 4 to be inserted with a margin. The projection 110 and the locking portion 103 are detachably locked between the nozzle portion 4 and the scattering prevention portion 100. However, since there is an extra space SP, as shown by a broken line in FIG. By moving in the direction, the nozzle part 4 can be swung freely and the ejection direction can be determined.

Further, since the wall portion 105 comes into contact with the direction in which the nozzle portion 4 is pushed in, the tip side of the scattering prevention portion 100 can be firmly contacted and supported by the to-be-cleaned portion such as the buttocks. Due to the positional stability of the scattering prevention unit 100 due to the contact support, the swinging operation of the nozzle unit 4 can be favorably performed using the scattering prevention unit 100 as a supporting member.

In the present embodiment, the scattering prevention portion 100 and the nozzle portion 4 are connected to the projection 110 and the flexible locking portion 103.
, But may be integrated as shown in FIG. In this case, it is necessary to take measures to promote the swing such as forming the vicinity of the base 106 of the scattering prevention portion 100 in a bell-like shape or using a highly flexible material so as not to impair the swingability. Further, as is clear from this figure, the shape of the scattering prevention portion 100 is not limited to a substantially cup shape, and may be such a funnel shape, and furthermore, it is not necessary to attach another member such as rubber to the tip. With such a curved surface shape, a sufficient buffering effect can be exhibited.

In this case, the scatter prevention unit 100 is used for the rotation operation for switching the ejection state as described later. If the large-diameter anti-scattering portion 100 is used for the turning operation, the turning power can be reduced and the operability is improved.

When the scattering prevention unit 100 is made detachable from the nozzle unit 4, it is easy to clean and replace the scattering prevention unit 100. When the scattering prevention unit 100 is not made detachable, the scattering prevention unit 100 is effectively prevented from being lost. It is a target.

From the upper front end of the nozzle portion 4, a base end is connected to and connected to the washing water passage R, and a nozzle portion 45 having a spout 4a formed at the front end is extended, and the outer peripheral surface of the nozzle portion 45 has an inner peripheral surface. Is attached, and by rotating the base side of the changing mechanism 46, the washing water can be switched between a mist state, a shower state, and a linear state. The injection mode changing mechanism 46 is configured such that the scattering prevention unit 100 does not interlock when the rotation is switched. Therefore, the scattering prevention unit 1
Rotational switching can be performed while the state of 00 is in contact with the part to be cleaned. Reference numeral 47 denotes a lever stopper. Even if the lever 44 is not pressed with a finger, the stopper 47 can be
When the lever 4 is engaged, the lever 44 can be held in the valve open state.

In this embodiment, the lever 44 is used only for opening and closing the flow passage. However, the operation switch of the pump P can be linked with the lever 44. At this time, if a gear pump or the like is used as the pump P, the flow in the flow path can be promptly controlled only by the operation switch of the pump, and the flow path opening / closing mechanism can be omitted.

Here, the nozzle portion 4 having the above-described configuration is connected to the main body portion 1.
The nozzle mounting unit 9 to be mounted on the nozzle will be described.

The nozzle mounting section 9 according to the present embodiment includes:

As shown in FIG. 2, the nozzle mounting section 9 has a lid 6 formed with a certain thickness, a cylindrical projection 60 formed in the center, and a nozzle insertion hole formed in the cylindrical projection 60. The nozzle unit 4 and the scatter prevention unit 100 are inserted into the water storage tank 10 with the ejection part 4a of the nozzle part 4 inserted into the spill prevention unit storage part 62 on the outer peripheral side. Can be held.

In this embodiment, the tip of the scatter prevention unit 100 is placed on a dedicated mounting part such as the scatter prevention part storage unit 62 with the tip side of the lower part facing downward. However, in the case of the present invention, since the tip of the delicate nozzle portion 4 has the scattering prevention portion 100, it does not directly contact the floor surface and is protected from external force, which is convenient.

In the above-described embodiment, the tip end of the scattering prevention portion 100 is shaped so as to contact the portion to be cleaned over the entire circumference. Because it will accumulate in 100,
It is also necessary to form a separate outlet 120 as shown in FIG.

Since the scattering prevention section 100 does not necessarily need to hermetically seal the part to be cleaned, the scattering prevention section 100 may have a shape in which the tip side of the scattering prevention section 100 only partially contacts as shown in FIG. Even in this case, the effect of supporting and fixing the head for swinging and the effect of preventing scattering are sufficient. Rather, such a shape eliminates the need for the above-described dedicated outlet, which is convenient.

The sanitary washing device A according to the present embodiment has the above-described configuration, and a case where this is actually used will be described below.

In use, the power cord 8 is connected between the main body 1 and the household outlet in advance, the storage battery B is charged, and the washing water in the water storage tank 10 is heated to an appropriate temperature by the heater H. Keep it.

For example, if the object to be cleaned is an elderly person or an infant requiring care, and the place of use is different, the power cord 8 is disconnected and the sanitary washer A is moved to the necessary place. The operation switch 71 is turned on to operate the pump P. At this time, as shown in FIGS. 1 and 2, since the nozzle portion 4 is held by the nozzle mounting portion 9 in a state where the lever 44 is in the valve opening operation position, the cold accumulated water in the hose 5 and the nozzle portion 4 is reduced. Water is discarded into the water storage tank 10 from the jet port 4a of the nozzle unit 4.

When the user lifts the nozzle section 4, the lever 44 returns to the valve closing position, so that the drainage stops. Thereafter, the tip side of the scattering prevention unit 100 is pressed against the portion to be cleaned. Since the scattering prevention unit 100 is fixed in the pressed state, the nozzle unit 4 can swing freely in this state. Here, when the user pulls the lever 44 toward the object to be cleaned, warm water heated to an appropriate temperature by the heater H is jetted. The spouted hot water can freely clean not only the local area but also the area of the scattering prevention unit 100 around the local area by changing the jetting direction of the nozzle portion.

In addition, since the splash of the washing water is blocked by the scattering prevention unit 100 during the washing, even when the work is performed on a bed or the like, the surrounding area is not polluted with the waste water.

[0052]

According to the present invention, as described above, the nozzle portion for ejecting the liquid is swingably supported, and the tip end side is provided with a scattering prevention portion located at least forward of the tip end of the nozzle portion. The tip of the scatter prevention part can freely contact the part to be cleaned, so the nozzle part can freely swing while the scatter prevention part is in contact with the part to be cleaned such as the buttocks, so the scatter prevention effect is sufficiently maintained It is possible to freely direct the nozzle tip to the vicinity of the local area while keeping the tip of the scattering prevention part in contact with the part to be cleaned. A good nozzle swing operation can be performed as a fixed portion. This has the operational effect of:
Furthermore, because the nozzle part and the scattering prevention part were made detachable,
Replacement and maintenance of the splash-prevention part that is easily soiled becomes easy, and the tip of the splash-prevention part has a curved shape. Obtained, resulting in firm contact. Further, by adopting a configuration as in claims 5 and 6, there is an effect that the washing water staying in the scattering prevention portion can be discharged smoothly.
