DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot-water circulating bathtub apparatus for maintaining hot water in a bathtub at a set temperature and keeping the water clear. In particular, the present invention relates to a hot water circulating bathtub apparatus that is optimal for business use such as hospitals and hot springs.

[0002]

2. Description of the Related Art A hot water circulating bathtub apparatus has been developed which can maintain hot water in a bathtub at a constant temperature and keep the hot water clear. This apparatus is provided with a heating means for keeping the temperature of the hot water constant, and a hot water refining member for keeping the hot water clear. The heating means maintains the hot water temperature at a constant temperature. The hot water refining member continuously decomposes and removes foreign substances such as dirt to keep the hot water clear.

[0003] Therefore, the hot-water circulating bathtub apparatus of this structure has a feature that a bath can be taken at any time for 24 hours without replacing hot water in the bathtub. This device can be used very conveniently, and since it does not drain after bathing, water can be effectively used and the water saving effect can be enhanced.

[0004] As a hot water refining member for keeping hot water clear, for example, inorganic natural stones and ceramics obtained by sintering an inorganic material in a porous state are often used. As the natural stone, for example, “barley stone” is used. Barite and porous ceramics allow microorganisms to live in a comfortable environment. Microorganisms decompose and remove ammonia (sweat), protein (dirt), and the like from the human body.

[0005] A hot water refining member for refining hot water by the action of microorganisms can keep the hot water clear for a long period of time, unlike a filter that simply filters foreign matter mechanically. For this reason, the hot water can be continuously circulated for 24 hours through the hot water refining member, and the hot water can always be kept in a clear state.

[0006]

In the hot water circulating bathtub apparatus, a hot water refining member is connected to the bathtub, and the hot water in the bathtub is circulated to keep the bathtub clear. The device of this structure can be conveniently used for a home bath. However, it cannot always be used in ideal conditions for business use such as hospitals and hot springs. For example, a nursing care tub of a type in which a person can take a bath while sitting in a wheelchair opens a part of the nursing care tub when the wheelchair is put in and out, so that hot water in the nursing care tub is drained and emptied. For this reason,
It becomes impossible to circulate the hot water in the nursing bath to the heating means and the hot water refining member. Also, in a nursing bathtub used for hospitals, a large number of patients may take a bath continuously at a time, or even if one person takes a bath, hot water may be rapidly stained. To clarify rapidly contaminated warm water, there is a large amount of circulation, in other words,
It is necessary to use an apparatus having a large clarification ability. However,
If a large-capacity device is used for a device in which a large number of things do not take a bath on average, it cannot be used efficiently, and there is a disadvantage that running costs and equipment costs are increased. Furthermore, nursing care tubs used in hospitals may be unconsciously excreted during bathing. For this reason, when the hot water in the nursing bath becomes dirty, it is important to be able to quickly clarify it.

The present invention provides a hot water circulating bathtub apparatus capable of quickly clarifying hot water dirt in a nursing care bathtub by using a unique structure as a whole instead of increasing the processing capacity of the hot water circulating bathtub apparatus. It was developed with the aim of providing.

Embodiments of the present invention will be described below with reference to the drawings. However, the following examples illustrate a hot-water circulating bath apparatus for embodying the technical idea of the present invention, and the present invention does not specify a hot-water circulating bath apparatus as follows.

Further, in this specification, in order to make it easier to understand the claims, the numbers corresponding to the members shown in the embodiments will be referred to as “claims” and “ In the column of “means”. However, the members described in the claims are not limited to the members of the embodiments.

The hot-water circulating bathtub apparatus shown in FIG. 1 circulates hot water in a large bathtub 1B, a bathtub 1 comprising a plurality of nursing bathtubs 1A and a large bathtub 1B, a sub-tank 4 into which hot water from the nursing bathtub 1A flows. A heating means 2 for keeping the hot water in the large bathtub 1B at a set temperature; and a hot water fining member 3 for keeping the hot water in the large bathtub 1B clear.

The heating means 2 and the hot water refining member 3 are
The warm water of B is circulated and keeps the warm water here clear,
Hold at set temperature. The hot water in the large tub 1B is the nursing tub 1
A, and the warm water in the care bath 1A is circulated from the sub tank 4 to the large bath 1B. That is, the hot water in the large tub 1B is circulated through the large tub 1B → the care tub 1A → the sub tank 4 → the large tub 1B to keep the hot water in the care tub 1A clear and at the set temperature.

In order to circulate the warm water in the large tub 1B to the nursing tub 1A, the nursing tub 1A is connected to the large tub 1B via a circulation pump 5 and a valve 6. The circulation pump 5 has a suction side connected to the bottom of the large bathtub 1B and a discharge side connected to the care bathtub 1A. Circulation pump 5 draws in hot water from the bottom of large bathtub 1B and supplies it to care bathtub 1A. The warm water in the nursing bath 1A is returned to the sub-tank 4 without passing through the circulation pump. The nursing bath 1A allows the hot water to overflow and flow into the sub tank 4. The overflowing hot water promptly discharges the floating foreign matter and circulates it to the sub tank 4.

The care bath 1A overflows hot water beyond the partition wall, or opens an overflow port in the middle of the partition wall to allow hot water to overflow from the overflow port. The overflowing hot water is supplied to the sub tank 4 without passing through the circulation pump. In order to allow the overflowed hot water to flow naturally to the sub-tank 4, the nursing tub 1A is higher than the sub-tank 4, more precisely, the overflow portion is higher than the water surface of the sub-tank 4, in other words, the overflow portion of the nursing tub 1A. The sub-tank 4 is disposed below.

[0021] All the care tubs are arranged on the bathroom floor,
The device in which the sub-tank is disposed below the floor can flow hot water overflowing from all the care tubs into the sub-tank. This device removes the overflowing hot water,
It can be made to flow on the floor of the bathroom, or flow down a ditch or pipe provided on the floor and flow into the sub-tank.

The valve 6 is an on-off valve or a check valve. The on-off valve closes when the circulation of hot water is stopped. The wheelchair-type nursing tub 1A drains hot water from the nursing tub 1A to empty it when the wheelchair is moved into and out of the nursing tub 1A. This is for opening a part of the nursing tub 1A and putting the wheelchair in and out. After carrying in the wheelchair, the peripheral wall of the nursing bath 1A is closed to supply hot water. When emptying the nursing tub 1A, the on-off valve is closed, the operation of the circulation pump 5 is stopped, and the outlet provided at the bottom of the nursing tub 1A is opened.
The hot water of A flows into the sub tank 4. At this time, the warm water discharged from the discharge port of the care bathtub 1A may be discarded and flow into the sub tank 4. When the care bath 1A is filled with warm water, the on-off valve is opened and the circulation pump 5 is operated to circulate the warm water in the care bath 1A to the sub-tank 4. When the bathing is completed, the hot water in the care tub 1A is drained and emptied, and then the care tub 1A is opened and the wheelchair is taken out of the care tub 1A.

The plurality of nursing tubs 1A are connected in parallel with each other, and hot water in the large tub 1B is circulated. Therefore,
A circulation pump 5 is connected between each care bath 1A and the large bath 1B. The nursing tub 1A, which does not drain hot water and empties, is a large tub 1B so that you can take a bath anytime.
Is continuously circulated for 24 hours. However, as shown by a chain line, the discharge side of one circulation pump 5 may be branched to circulate hot water to a plurality of care bathtubs 1A.

The sub-tank 4 is provided at a position where it does not obstruct the bathroom or outside the bathroom. Sub tank 4
It is a sealed tank that has been insulated. The volume of the sub-tank 4 is preferably approximately equal to or larger than the volume of one care bath 1A. When the sub-tank 4 is enlarged, temporary dirt in the nursing bath 1A can be diluted and returned to the large bath 1B. This is because even if dirty hot water is circulated from the care bathtub 1A to the sub-tank 4, the hot-water dirt in the sub-tank 4 can be reduced. However, a large sub-tank has a large installation area, a large surface area, and a large amount of heat dissipation. For this reason, preferably, the sub tank 4
Is designed to be smaller than the sum of the volumes of all the connected care baths 1A and larger than the volume of a single care bath 1A.

The sub tank 4 is connected to a large bath 1B via a strainer 10 and a reflux pump 12. The operation of the reflux pump 12 is controlled by the water level sensor 7 of the sub tank 4. The water level sensor 7 controls the operation of the reflux pump 12 to maintain the hot water level of the sub tank 4 at a set value. The water level sensor 7 stops the operation of the reflux pump 12 when the hot water level of the sub-tank 4 falls below the set value, and operates the reflux pump 12 when the hot water level becomes higher than the set value, and discharges the hot water of the sub-tank 4. Supply to large bathtub 1B.

Hot water is circulated between the heating means 2 and the hot water fining member 3 by a circulation pump 9. The heating means 2 can use all means for heating the hot water in the large tub 4 to a set temperature, for example, a gas burner, a kerosene burner, a heat exchanger heated by a heat storage material heated by electricity, an electric heater, and the like. . The heating means 2 has a built-in temperature sensor (not shown). The temperature sensor detects the temperature of the hot water sucked from the sub tank 4 and controls the burner and the electric heater to heat the temperature of the circulated hot water to a set temperature.

The hot water refining member 3 keeps the hot water circulated clear. The hot water fining member 3 is optimally a member that inhabits microorganisms such as bacteria and keeps the fins clear. As the warm water clarifying member 3 in which microorganisms inhabit, a material obtained by crushing a porous natural stone such as barley stone into predetermined granules, or a material obtained by binding a powdered material such as a natural stone or a ceramic to a porous state can be used. . Further, as the hot water fining member 3, a filter or the like that keeps the hot water clarified by a photocatalyst can be used.

And circulate through the large bathtub 1B. This structure is suitable for an apparatus using a heat exchanger as the heating means 2. This is because when the temperature of the hot water in the large bathtub 1B rises to the set value, the control valve 11 is closed to stop the circulation to the heat exchanger, and the heat radiation of the heat exchanger can be reduced. The control valve 11
The valve is opened when the temperature of the hot water in the large tub 1B is lower than the set value, and the hot water is heated by the heat exchanger. At this time, the heat exchanger is heated by a burner or the like. When the hot water temperature rises to the set value, the control valve 11 is closed, and the heating of the heat exchanger also stops.
This structure also has a feature that a large amount of hot water can be circulated to the hot water fining member 3 without heating the hot water, and the hot water fining member 3 can efficiently clarify the hot water.
