Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bathtub unit that serves as a seat for elderly people, cripples, and other people with physical disabilities, and in which one side wall of the bathtub can be opened.

Known constructions of this type have the disadvantage that the bather has to sit in the bathtub for a relatively long time until the required amount of hot water is filled into the bathtub or until the bathtub is drained of hot water. The long waiting time after bathing is a particular problem. This is because the person who has taken a bath has to wait while still wet, and this can easily lead to inducing X-evil.

The present invention relates to a bathtub unit of the above-mentioned type in which a bather does not have to wait in the bathtub for a short period of time before or after bathing until the bathtub is full or empty. The purpose is to provide

According to the present invention, this problem can be solved by providing a hot water collection tank below the bathtub, which is connected to the bathtub through a large-diameter drain pipe and can accommodate the entire amount of hot water in the bathtub, and preferably also has a large-diameter drain pipe. This can be achieved by providing a hot water storage tank that is connected to the bathtub through a hot water inflow pipe and can accommodate the entire amount of hot water in the bathtub. This substantially reduces the time traditionally required to fill or empty a bathtub, thus leaving the bather wet or naked for potentially disease-inducing lengths. The situation of having to wait in the bathtub for hours can be avoided.

In a preferred embodiment, the bathtub drain valve is open into the water collection tank, thereby allowing a particularly rapid draining of the bathwater. This is because the bathtub is equipped with a large-diameter drain valve, so that the hot water first flows quickly into the hot water collection tank, and from there it can be drained through the drain pipe at a normal speed.

The hot water storage tank is preferably formed as a pressureless vessel and is thermostatically operated, as is known per se, so that the temperature of the bath water can be precisely measured and immediately available to flow into the bath.

In this case, the bath water inlet is provided in the upper area of the bathtub side wall of the bathtub unit to avoid premature splashing by the bather while filling the bathtub.

Further, for example, in the case of a heart disease patient, it is preferable that hot water flows into the bathtub from below.

Another object of the invention is to provide a bathtub which requires little space with respect to the openable side walls and which requires a simple seal. In this case, bathtubs of the above-mentioned type must have low energy costs in terms of hot water consumption, and their production costs must be low, given that elderly and disabled people are often in a disadvantageous economic situation. It must be taken into account that the installation must be of a minimum cost and that it can be installed even in houses where it is not possible to provide a separate bathroom.

These problems are solved according to the invention by providing a bathtub unit in which the openable side wall can be moved downwards, towards the bottom of the bathtub, and for this purpose no additional space is required. .

Preferably, the openable side wall is configured to be arched in cross-section and is capable of sliding along an arched guide extending into the lower half of the bathtub;
This makes it possible to move the side wall particularly easily and stably. 3. The upper part of the slidable side wall piece (slidable piece) is bent outwards, so that when the side wall is open, the bent part is It is configured to be located on the same horizontal plane as the bottom, thus providing a step stool for easy entry into the bathtub. Furthermore, this sliding piece is sealed with a lip seal known per se to the bathtub area to which it is fixed. This allows particularly easy sliding. This is because the lip seal is pressed tightly against this slidable piece by water pressure when the bathtub is filled. Finally, this openable side wall may be formed by a flat plate, the lower end of which is slidable in the guide and can be pivoted by means of a pin held in the guide, and The object is achieved of providing a particularly simple and light construction of the releasable side walls.

The invention will now be explained in more detail in connection with the embodiments shown in the drawings.

The first embodiment of the unexploded seat bathtub unit is a seat bathtub 1,
It consists of a hot water storage tank 2 formed as a pressureless container, and a hot water collection tank 8 provided below the bathtub 1 and having a drain pipe 14.

The bathtub 1 has a seat 1' and an openable side wall 1'', which consists of three side wall pieces 8.9.10. Number 4 indicates the bath water inflow pipe, and the pipe opening 4' is the oak! &5 located at the bottom. Drain valve 6ii of the bathtub 1 The drain valve of a normal bathtub is also formed with a substantially large diameter so that the bathtub can be emptied quickly. The drain valve 6 opens into a hot water collection tank 8, and the hot water collection tank is formed as a buffer container between the drain valve 6 and the drain pipe 14. Number 7 is the head of the bather.

A lip seal 11 (FIG. 6) is used as a sealing backing between the side wall piece 8.9.10 and the bathtub 1.
This is pressed against the side wall piece by the cross-section pressure piece 12.

The lip seal 11 has a horizontally inwardly directed arcuate seal end 11' which abuts the opposite tub sealing piece 15 at the closed side wall 1#. The opposing sealing piece 15 is
It is assembled into the bottom of the bathtub and is formed in the shape of a groove extending in the longitudinal direction of the bathtub, and a packing piece 11' is pressed into this groove by water pressure. Side wall piece 8.9.1 in separate bathtub area
0 are sealed to each other in their lower part by lip seals 18), the lip seals running parallel to the right angle corners of the side wall pieces.

The hot water storage tank 2 is provided with a heating cartridge 16, which in this embodiment is controlled by an electrically operated thermostat, to heat the stored bath water. However, it is also possible to heat the water as it flows from the tank, but in this case an automatically operated mixing valve must be provided to maintain a constant temperature of the water entering the bathtub.

FIG. 4 shows the bathtub unit in a state in which it can be entered into the bathtub, i.e. in a state in which the side wall 1'' is open. In this case, the bather can freely approach the seat 1' inside the bathtub.Two hot water storage tanks have the necessary amount of hot water prepared in a heated state.The bather can enter the tank in this state. be able to.

The closing mechanism of the side wall 1" is then actuated, and the side wall pieces 8.9,
lO is first slid in the longitudinal direction of the tank to its predetermined position,
Then the seal end of the lip seal 11.18 is lowered. On the left, when the three side wall pieces 8, 9 and 10 are closed, the control switch opens the sprue and hot water flows into the hot water inlet pipe 4.
The water flows into the bathtub from the inlet 4', that is, flows along the side wall of the bathtub.

The time required to fill the bathtub is only 20 to 8
0 seconds, and the bather only needs to wait a short time in the bathtub. At this time, due to hydrostatic pressure] lip seal 11.1
The packing end 11' of No. 8 is pressed against the corresponding packing surface. However, if water leaks, it flows to the hot water collection tank 8 as shown in FIG. 5, so that the water does not reach the floor.

When the bather finishes bathing, the drain valve is opened by a manual switch, and the bath water is drained into the hot water collection tank 8 in about 20 seconds, and the tank 8 receives all the bath water. Drain pipe 14 provided in the hot water collection tank 8
There is a conventional odor barrier, not shown, between the drain station and the drain station.

The hot water collection tank 8 is equipped with a conventional float switch.
When the water level in the hot water collection tank reaches a level corresponding to the total amount of hot water flowing out of the bath 4!11, the mechanism for opening the side wall 1" is actuated. This causes the side wall pieces 8.9.10 to slide against each other and this After taking a bath, the person can get out of the bathtub.At the same time, the hot water collection tank 8 is emptied and the hot water storage tank 2 is filled, so that the bathtub unit is ready to be used for bathing again.

The actuation of the side wall pieces 8.9.10 is carried out hydraulically by means of a cylinder, which is actuated by pressurized line water. Control of the cylinder is done electrically with a voltage of 24 volts. The entire structure may be made of synthetic resin.

Similarly, the bathtub units shown in FIGS. 8 to 11 are the zashu bathtub 1,
The bathtub consists of a hot water storage tank 2 which can supply hot water prepared by a float valve, and a hot water collection tank 8 which is provided below the bathtub 1 and has a drain pipe 14 (FIG. 8). The bathtub 1 is equipped with a seat 1' and an openable side wall r (FIG. 10). Side wall 1" consists of a slidable piece 21 that can slide the lower part of the bathtub bottom 20 downwards. Number 22 is a hot water groove entry pipe provided at the upper part of the bathtub.

The sliding piece 21 constituting the openable fill wall l" has a cross section curved in an arch shape, and each point in the curve is numbered 26.
(Fig. 11). A lip seal 28 (FIG. 11) is provided for cushioning between the sliding piece 21 and the fixed bath area. The sliding piece can slide in a lateral, likewise curved guide, which extends to the lower part of the bathtub 20.

The upper castle 21' of the sliding piece 21 bends outward, and when the sliding piece 21 slides down to the bottom of the bathtub, it reaches the same horizontal plane as the bottom of the bathtub.

In a third embodiment, the openable side wall 1 is formed from a flat plate 24, which is guided by the bottle in a guide 25, so that it can be pivoted (FIG. 12). . The guide part 25 is disposed obliquely downward under the bathtub bottom 20, and the outward bending castle 24' at the upper part thereof is bent when one side wall is in the open state, i.e., as in the case of the second embodiment described above. When the side wall piece turns, it can be positioned on the same horizontal plane as the surface of the bathtub bottom 20. When closing the side walls, a stop is provided at the outer end of the guide 26, which prevents the plate 24 from being pulled out further. When the plate 24 expands, it snaps and is strongly pressed against the upper seal packing 28, thereby making it possible to completely seal the tank.

FIG. 8 shows the bathtub unit in a ready-to-bath state, that is, with the side wall 1'' open. For this purpose, the sliding piece 21 slides downwards. In this case, the upper area bent outwards is becomes a stepping stone on which you can easily step (Fig. 11, sliding piece 21
dotted line position). The required amount of hot water is prepared in the hot water storage tank 2 as in the first embodiment. In this case, the hot water storage tank may be filled with water and a conventional heating device may be operated. When the temperature of the hot water in the hot water storage tank 2 reaches a desired level, the release thermostat, which operates independently of the second control thermostat, activates the multiple device (this is a dual temperature control system). When the control lamp turns on, it indicates that the bathtub unit is ready. Furthermore, a display thermometer may be provided for temperature control.

The bather is thus able to sit in the bathtub, which is relatively easy even for the elderly and the disabled due to the freely accessible seat 1'. Next, when a push button provided on the edge of the tank is pressed, the closing mechanism is activated, and the sliding piece 21 is slid upward by two hydraulic cylinders operated by the water pressure of the pipe.

When the slidable part 21 reaches its final position, the control switch opens the hot water tap and hot water flows through the hot water inflow pipe 22.
That is, it flows into the bathtub 1 along the inner circumference of the bathtub. The silicone packing 28 is pressed against the slidable portion 21 by hydrostatic pressure. Although some leakage water reaches the water collection tank 8, no water leaks from the tank 8 onto the floor.

The state of operation is similar to that of the embodiment of FIGS. 1-7.

The operation of the embodiment shown in FIG. 12 is the same as that of the embodiment of FIGS. 8-11.

In both embodiments, the overall functional progression is program-controlled by a pushbutton located on the rim of the tank.
A switch can be turned on. The individual valves and openable side walls can be electrically, hydraulically or pneumatically actuated.
