SUMMARY OF THE INVENTION US Pat.
The outline of the wheelchair washer indicated by 375 is shown in FIG. The wheelchair 101 is stored inside the wheelchair washer 100, and the shower 10 of the cleaning liquid is supplied from a shower nozzle provided on the ceiling.
Give 2 baths. The shower is a wheelchair wheel periphery 10.
3 and axle 104 and seat 105.
The problem here is the axle grease. The axle is provided with bearings for smooth rotation of the wheels, and the bearings are coated with grease. If grease is lost, smooth rotation will be impaired. In the wheelchair washer shown in FIG. 6, the entire wheelchair is showered, so that the grease applied to the axle is washed away as well as dirt. Even if wheelchairs can be easily cleaned by using a wheelchair washer, it is necessary to apply grease to the axle after that, and there is a problem that wheelchair cleaning is troublesome when viewed comprehensively. Was.

[0004]

According to the wheelchair washer of the present invention, in addition to cleaning the wheelchair with ultrasonic cleaning water, the axle grease portion is not immersed in the ultrasonic cleaning water, or in addition. The washing water is electrolyzed water, or, in addition to washing the wheelchair with ultrasonic cleaning water and the axle grease portion not being submerged in the ultrasonic cleaning water, the seat below the axle grease portion has a seat. The wheelchair is fixed so that it is located, or the wheelchair is submerged in the ultrasonic cleaning water in addition to cleaning the wheelchair with the ultrasonic cleaning water and the axle grease portion does not submerge in the ultrasonic cleaning water. The level of the ultrasonic cleaning water is controlled by controlling the volume of the air bag.

[0005]

According to the wheelchair washer of the present invention, in addition to cleaning the wheelchair with the ultrasonic cleaning water, since the axle grease portion is not immersed in the ultrasonic cleaning water, the wheelchair is sufficiently stained during the wheelchair cleaning. Dropping and retaining axle grease can be achieved at the same time. The axle part cannot be washed with the ultrasonic cleaning water, but even in a new wheelchair that is not soiled, this axle part is a part where grease is originally attached and there is a concern that a patient or a nurse may be stained. Since the structure has been devised so as not to touch, the clothes of patients and nurses do not become dirty and the running floor surface does not become dirty due to inability to wash. When the washing water is electrolyzed water, dirt on a wheelchair can be cleaned by alkaline water or acidic water generated by electrolysis of water. If a device for electrolyzing water is provided, there is no need to purchase and store the cleaning liquid, and the cleaning liquid can be freely selected according to the type of dirt by an electrical operation that is easily automated. For example, it is possible to selectively use alkaline ionized water for protein-based stains and acidic ionized water for metal surface stains. When the wheelchair is fixed such that the seat is positioned below the axle grease portion, the seat can be sufficiently cleaned with the cleaning liquid. When controlling the level of the ultrasonic cleaning water by controlling the volume of the air bag immersed in the ultrasonic cleaning water, controlling the volume of the air bag according to the degree of air supply to the air bag. Can control the water level of the cleaning liquid. The sum of the volume of the stored cleaning liquid and the volume of the air bag submerged in the cleaning liquid is the effective cleaning liquid volume.

FIG. 1 shows an embodiment corresponding to claim 1 of the present invention. Wheelchair 101 is a wheelchair washer 1 in the shape of a bathtub
It is tilted and fixed as shown in the figure during 00. The posture of the wheelchair is determined by the wheelchair holding roller 1. When the front wheels and the main wheels are held so that the heights of the axles 104 are equal, an inclined posture as shown in the figure is obtained. The wheelchair washer is filled with the oily detergent 2 so that the water level is lower than the axle height, and is vibrated by the ultrasonic generator 3. When this state is maintained, the dirt on the part immersed in the cleaning liquid is lifted and removed. Since the wheelchair holding roller is a rotary long rod, the front wheel and the main wheel mounted thereon can rotate, respectively. Maintaining the wheelchair in the cleaning solution while rotating the wheel cleans the entire wheel. When the grip 4 of the wheelchair is pulled down and immersed in the cleaning liquid, the grip, the backrest 5, and the seat 105 of the seat can be cleaned in the cleaning liquid. As described above, in the wheelchair washer of FIG. 1, the main part of the wheelchair can be cleaned by rotating the wheel of the wheelchair or changing the posture while keeping the axle from being immersed in the cleaning liquid.

An embodiment according to claim 2 of the present invention will be described. In FIG. 1, ionized water is used instead of the oil stain detergent. Ionized water is generated by electrolyzing water. In some cases, an ionized water generator is provided outside the wheelchair washer depicted in FIG. 1, or in the washer itself of FIG. 1 the electrode for ionization and water are separated. In some cases, partition walls are provided.

FIG. 2 shows an embodiment corresponding to claim 3 of the present invention. A wheel outer peripheral portion 103 of a wheelchair 101 is supported by a wheel holding roller 1 provided in the wheelchair washer 100. The axle 104 keeps its posture so as to come out on the surface of the washing liquid 2. In the cleaning liquid 2, main parts such as an ultrasonic generator 3, a grip 4, a backrest 5, and a seat 105 are submerged. The wheels can be rotated so that all of them are immersed in the cleaning liquid.

A first embodiment according to claim 4 of the present invention is illustrated in FIGS. FIGS. 3 and 4 are similar to FIG. 2 except as noted herein. FIG. 3 shows a case where the water level of the cleaning liquid 2 is low with the air bag 6 deflated. Compared with FIG. 2, the cleaning liquid is contained only a little. In the state of FIG. 4 in which the air bag 6 is inflated, the water level of the cleaning liquid 2 has risen.
The level of the water surface is adjusted to be lower than the height of the axle 104 so that the air bag is inflated.

FIG. 5 illustrates a second embodiment of the present invention. The configuration is the same as that of FIG. 2 except for the description here. In this embodiment, one end of the wheelchair washer 100 is cut low, so that when the water level reaches a certain level, the cleaning liquid 2 overflows and becomes drainage 7. If the cut position is set lower than the axle 104, the water is drained so that the water level does not become more than necessary. In the embodiment of FIG. 5, a state in which a part of the cleaning liquid 2 is drained by inflating the air bag 6 is illustrated. Air bag 6
By greatly inflating, all the cleaning liquid inside the wheelchair washer can be drained.

[0011]

According to the wheelchair washer of the present invention, the main part of the wheelchair can be sufficiently cleaned without damaging the axle grease. In the case where ionized water is used, the cleaning liquid can be produced by ionizing the water at a necessary time, so that unnecessary storage of the cleaning liquid is avoided. The use of ionized cleaning water also suppresses global environmental pollution. When the water level is raised with an air bag, the washing liquid can be saved and drainage can be performed without providing a special drain.
