Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub capable of half body bath.

[0002]

2. Description of the Related Art Conventionally, a bathtub installed in a home is generally formed so as to have a full-body bath with hot water even up to the shoulder. This whole-body bath may be subject to about 1 ton of water pressure on the body, and bathing may be severe for people with weak internal organs.

[0003]

SUMMARY OF THE INVENTION Therefore, the present invention should solve the problem of providing a body-friendly half-body bath, that is, a bathtub capable of both a bath without an excessive water pressure on the upper body and a normal whole-body bath. This is an issue.

[0004]

[Means for Solving the Problems] A technical means for solving the above problems is to use a bathtub capable of both a half body bath and a whole body bath.
Water level detecting means for detecting the water level of the bathtub body, water level setting means for setting the water level, water level adjusting means for at least reducing the water level, and the water level while recognizing the water level detected by the water level detecting means And a control means for controlling the water level adjusting means so that the water level is set by the setting means.

[0005]

According to the bathtub having the above construction, the control means controls the water level adjusting means so that the water level is set by the water level setting means while recognizing the water level detected by the water level detecting means. If the water level set by is a water level equivalent to a half-body bath, a half-body bath is possible, and if the water level set by the water level setting means is a water level equivalent to a whole-body bath, a whole-body bath is possible.

[0006]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a configuration system diagram schematically showing the configuration of the first embodiment. As shown in FIG. 1, a water pressure sensor 2 that detects water pressure according to the water level of the bath body 1 is attached to the bottom surface of the bath body 1. In addition, this water pressure sensor 2
Instead of, a water level sensor that directly detects the upper surface level of the hot water of the bath body 1 may be used.

A hot water storage tank 3 is provided outside the bath body 1, and an electric pump 4 is provided in the hot water storage tank 3. When this electric pump 4 is suctioned,
Since the hot water in the bathtub body 1 is sucked up into the hot water storage tank 3, the hot water in the bathtub body 1 is reduced, and a body-friendly half-body bath, that is, an appropriate water level when taking a bath without excessive water pressure on the upper body can be obtained. it can. On the other hand, when the electric pump 4 is discharged, the hot water in the hot water storage tank 3 is discharged to the bath body 1. Moreover, a jet jet flow to the bathtub body 1 is also possible.

The controller (control means) 6 shown in FIG.
Is for controlling the electric pump 4 and the heater 7 provided inside the hot water storage tank 3. Therefore, on the input side of the controller 6, the water pressure sensor 2 (water level sensor) and
A water level setting device 8 for setting an appropriate water level for the body-friendly half-body bath and the normal whole-body bath is connected. The water level setting device 8 is composed of a changeover switch. When the water level is switched to the half body bath mode, the controller 6 controls the electric pump 4 so that the water level corresponds to the half body bath, while the whole body bath mode is set. When switched to the mode, the controller 6 controls the electric pump 4 so that the water level corresponds to the whole body bath. In order to perform such control, the electric pump 4 and the heater 7 for keeping warm water in the hot water storage tank 3 are connected to the output side of the controller 6.

In the bathtub constructed as described above, when the water level setting device 8 is switched from the whole body bath mode to the half body bath mode while the bath body 1 is filled with sufficient hot water, the control is performed. The la 6 recognizes the current water level based on the signal from the water pressure sensor 2, and then causes the electric pump 4 to perform suction operation to suck hot water from the bath body 1 into the hot water storage tank 3 and gradually warm the hot water from the bath body 1. Water pressure reduction 2
The operation of the electric pump 4 is stopped when the signal from the water level matches the water level corresponding to the half-body bath. In this state, it is possible to take a half-body bath without any physical problems.

On the other hand, when returning the warm water sucked up in the hot water storage tank 3 to the bath body 1, the water level setting device 8 is used for the whole body bath mode.
Then, the electric pump 4 is discharged.
As a result, the hot water in the hot water storage tank 3 is discharged to the bathtub body 1, and the hot water in the bathtub body 1 is increased to the water level corresponding to the whole body bath.

Next, a second embodiment of the present invention will be described. In the second embodiment, the body level data of an individual who uses this bathtub is stored in the memory circuit of the controller 6 without using the water level sensor, and the half-body bath mower is set by the water level setting device 8. When the mode is set, the controller 6 calculates how many liters of hot water to be drawn from the bathtub body 1 into the hot water storage tank 3 based on the physical data of the individual, and then operates the electric pump 4 to draw it. Let On the other hand, when the whole body bath mode is set by the water level setting device 8, the controller 6 causes the electric pump 4 to be discharged and the hot water in the hot water storage tank 3 is returned to the bath body 1 in the same amount as the above-mentioned suction amount. To do.

Next, a third embodiment will be described. Third
In the embodiment, as shown in FIG. 2, when the bather's hand touches, the human body sensor 10 detects the body temperature, pulse, etc. of the person.
The water temperature sensor 11 and the water temperature sensor 11 are provided in the bathtub body 1, and the human body sensor 10 and the water temperature sensor 11 are connected to the input side of the controller 6. With this configuration, the controller 6 gradually raises the temperature of the hot water supplied to the bath body 1 from about 38 ° C. to a temperature according to the body temperature of the bather, the pulse, the presence or absence of a jet jet, and the like.

Next, a fourth embodiment will be described. Fourth
In the embodiment, as shown in FIG. 3, a concave portion 1A into which the foot 13 of the bather 12 is inserted is provided on the inner surface of the bath body 1 so that the legs 14 of the bather 12 can be extended, so that when bathing a half body bath. However, the kneecap 12B of the bather 12 is kept out of the hot water. The bottom surface of the bathtub body 1 may be formed in an inclined shape instead of providing the concave portion 1A. That is, since the conventional general bath body 1 is formed to have an inner surface shape as shown in FIGS. 1 and 2, the kneecap of the bather goes out of the hot water during a half-body bath. However, the fourth embodiment solves this problem because there is a problem that it is hard to heat up.

[0014]

As described above, according to the present invention, the water level detecting means for detecting the water level of the bathtub body, the water level setting means for setting the water level, and the water level adjusting means for at least decreasing the water level, With a control means for controlling the water level adjusting means so as to reach the water level set by the water level setting means while recognizing the water level detected by the water level detecting means, a bather is a body-friendly half-body bath, and You can take a normal whole body bath.
