Description

[Detailed Description of the Invention] The present invention relates to a bathing device for people with motor impairments.

Some conventional devices have a structure in which a bubble plate is removably attached to the bottom plate of a bathtub, but when cleaning a bathtub, the worker puts his or her upper body into the bathtub and attaches the bubble plate. The bubble plate had to be attached and detached, and the work of attaching and detaching the bubble plate during cleaning work was troublesome.

In addition, other conventional devices have many small holes in the bottom plate of the bathtub, and the bottom plate of the bathtub also serves as a bubble plate. Because it is located at the bottom, dirt and limescale from the hot water bath adhere to the small hole and the air passageway below it, causing clogging of the air port and making the inside of the bathtub unclean.

In addition, there are other conventional devices in which a bubble plate is connected to a frame body made of pipe material that moves up and down, and the frame body and the bottom wall of the bathtub are connected by a telescopic air introduction pipe. The structure of the air introduction pipe is complicated, which leads to high costs, and also causes trouble in the lifting and lowering mechanism of the frame, making maintenance difficult.

Therefore, the purpose of the present invention is to provide a bathtub that is easy to maintain and easy to maintain by reducing the labor involved in cleaning.

That is, in the present invention, the bottom plate 2 of the bathtub 1, which has a frame 5 on which a stretcher 4 is placed and moves up and down, is provided with a discharge outlet 7 for discharging compressed air, and is detachably attached to the frame 5 to remove air bubbles. The lower surface of the air bubble plate 6 that is generated is provided with a receptacle part 15 for taking in the compressed air, and when the air bubble plate 6 is lowered with the lowering of the frame 5, the discharge outlet tool 7 is disposed.
This is a bathtub with a bubble plate connecting device characterized in that the and the socket part 15 are joined and communicated internally.

The discharge outlet tool 7 includes a cylinder 8 having a cylindrical outer shape, a donut-shaped valve seat 11 horizontally covering the upper part of the cylinder 8, and a center portion located below the valve seat 11. The valve stem 13 is erected and pressed against the valve seat 11 by a push-up spring 10.
The discharge port tool 7 is opened by pushing down.

Next, the configuration of an embodiment of the present invention will be explained in detail based on the accompanying drawings.

An elevating cylinder 3 that expands when pressure water is injected into the bathtub 1 and descends when the internal pressure water is discharged is installed on the bottom plate 2 at approximately the center of the bathtub 1, and a stretcher 4 is mounted on the upper end of the elevating cylinder 3. A frame body 5 for placing the
A thin rectangular bubble plate 6 with a hollow interior is detachably attached to the upper surface of the frame 5 using an appropriate member such as a knob screw.

The bubble plate 6 is covered with a bubble plate 6 on the bottom plate 2 of the bathtub 1.
A discharge outlet 7 for discharging compressed air is provided at a position corresponding to the socket 15 provided on the lower surface.
is screwed onto the bottom plate 2 as shown in FIG. A push-up spring 10 is provided, a donut-shaped valve seat 11 is screwed horizontally above the cylinder 8, and a donut-shaped sealing material 12 is adhered to the upper surface of the valve seat 11. A valve stem 13 is protruded from the center of the upper circular plane of the valve 9, and is positioned so as to pass upward through a hole in the center of the valve seat 11. A plurality of holes 14 through which air flows are provided at positions on the top surface of the valve 9 in contact with the valve seat 11.
is opened.

A receptacle portion 15 for receiving compressed air is provided at a position of the air bubble plate 6 that faces and comes into contact with the discharge outlet tool 7 when the air bubble plate 6 is lowered together with the frame body 5.
A collar 16 is provided at a position where it comes into contact with the cushioning material 12 of the discharge outlet tool 7.

Air ports 18, which are small through-holes, are formed at a number of appropriate locations on the upper plate 17 of the bubble plate 6.

A blower 20 that sucks in and compresses outside air is provided in the machine installation section 19 adjacent to the bathtub 1. A discharge port 21 of the blower 20 is connected to the discharge port 7 through an air pipe 22. A safety valve 26 is provided at an appropriate position to release air pressure when air pressure equal to or higher than a predetermined pressure is applied.

An operating section 23 for rotating and stopping the blower 20 is provided above the machine installation section 19. Pressure water such as tap water is obtained from the lower outside of the machine installation section 19, and this pressure water is sent to the lifting cylinder 3. A switching valve 24 is provided to switch the channel for supplying water to the cylinder 3 or discharging the pressure water filled in the lifting cylinder 3, and a pedal 25 for operating the switching valve 24 is provided.
is provided in the switching valve 24.

The operation of the present invention with the above configuration will be described below.

The caregiver places the stretcher 4, on which the patient is lying on his back with his head raised, on the stretcher 5, which has been raised to its highest point, and
Thereafter, the caregiver depresses the pedal 25 to contract the elevating cylinder 3 by the weight of the frame 5 and the patient, simultaneously lowering the patient on the elevating cylinder 3, and immersing the patient in the warm water filled in the bathtub 1.

When the pedal 25 is depressed to drain the water in the lifting cylinder 3 and retract the lifting cylinder 3, the bubble plate 6 is lowered together with the frame 5, and the socket 15 of the bubble plate 6 is lowered.
and the outlet fitting 7 of the bathtub bottom plate 2 are brought into contact with each other and communicated internally.

That is, when the bubble plate 6 descends in the direction of arrow A and reaches the lowest point, the collar 16 and the sealing material 12 come into close contact with each other in an airtight manner, and the upper plate 17 of the bubble plate 6 moves upward from the valve 9 inside the cylinder 8. comes into contact with the upper end of the valve stem portion 13 protruding from the
As the upper plate 17 is lowered, the valve stem 13 is pressed downward, and the valve 9 is pushed up, overcoming the tension force of the spring 10 and sliding downward, thereby creating a gap between the valve 9 and the valve seat 11. When a gap is created between the valve 9 and the valve seat 11, the pressure air generated by the blower 20 and guided by the air pipe 22 passes through the holes 14 provided around the valve 9, and then passes through the valve seat 11 and the sealing material 12. It flows through the central passage towards the receiving part 15 of the bubble plate 6.

The compressed air flowing into the bubble plate 6 is ejected from a number of air ports 18 provided in the upper plate 17 to generate bubbles in the bathtub 1, and the bubbles are administered to a patient located above the bubble plate 6.

On/off control of the blower 20 is performed by operating the operating section 23.

When the pedal 25 is stepped on and pressure water is poured into the lifting cylinder 3 to extend the lifting cylinder 3 and raise the frame 5 and the bubble plate 6, the socket 15 and the discharge outlet 7 are separated, and the socket 15 and the discharge opening are separated. Communication with 7 is canceled. That is, when the upper plate 17 of the bubble plate 6 rises, the downward pressure on the valve stem 13 is released, and the valve 9 is pushed up by the push-up spring 10 and tightly contacts the valve seat 11, so that the hole 14 of the valve 9 is closed and the air pipe 22 The compressed air coming from the air bubble plate 6 is closed by the valve 9 and does not flow into the bubble plate 6.

The frame 5 is raised to the highest point and the stretcher 4 carrying the patient is lowered from the frame 5 to complete the bathing.

The effects of the present invention having the above configuration and operation will be described below.

The air bubble plate is not attached to the bottom plate inside the bathtub, but instead is attached to and removed from the frame that moves up and down inside the bathtub, so when cleaning the inside of the bathtub, you can put your upper body into the bathtub and remove the air bubble plate from the bathtub. The labor required for cleaning is reduced because the bubble plate can be attached and detached at the same level as the upper edge of the bathtub without having to clean it at the inner bottom plate. Furthermore, since the bottom plate of the bathtub does not have any unevenness caused by screws for attaching the bubble plate, it is easy to clean, and it is possible to keep it clean by reducing the adhesion of dirt, etc., and eliminate rust caused by deposits, thereby extending the life of the bathtub. Ta.

Furthermore, because the bottom plate of the bathtub is not configured to be used as a bubble plate and the bubble plate is not installed in a fixed manner as in the past, sediment and limescale may enter and adhere to the bubble plate, and foreign objects may clog the air vents. This makes it possible to reduce dirt inside the cell board and make maintenance of the cell board easier.

In addition, since a valve is installed in the discharge outlet device, when the frame is raised to finish bathing, the discharge of compressed air is automatically stopped, and a large mass of air bubbles can cause the hot water surface to become rough, causing damage to the patient's head. This eliminates the possibility of splashing hot water and causing pain to the patient, and at the same time prevents the generation of unnecessary air bubbles, which has the effect of reducing the drop in water temperature.

In addition, this invention does not use the conventional telescopic air introduction tube, but instead has a structure that allows air bubbles to be administered to the patient as needed at the time of bathing, so the structure is simple and it does not require much effort to operate the frame's elevating device. This helps reduce breakdowns and is advantageous in terms of maintenance.
