Abstract

PROBLEM TO BE SOLVED: To prevent stagnation and occurrence of slime by providing the proper number of hot water sucking holes which are arranged opposed to the fitting surface of a bath tub so as to communicate with a sucking port in a sucking unit and also hot water jetting holes which are arranged opposed to the fitting surface of the bath tub so as to communicate with a jetting port in a jetting unit. SOLUTION: When a circulation pump is operated, hot water inside the bath tub 1 is sucked from the sucking port 13 of the sucking unit 3. At this time, hot water which does not easily flow and is stopped at the back surface of the sucking unit 3 is sucked from the sucking hole 17 on the back surface of a housing 10 and the sucking hole 19 in a lower part so that a water flow is generated. Moreover, hot water sucked from the sucking unit 3 is jetted from the jetting unit 8 to the inside of the bath tub 1 again by way of a filtering device and a heating device inside a device mainbody so as to execute circulation. In this case, a part of hot water is jetted from a jetting nozzle 26 towards the wall surface of the bath tub 1 and diffused along the wall surface of the bath tub 1 so that hot water at the back surface of the jetting unit 8 is permitted to flow and the water flow is generated.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a circulation type hot water bath according to the present invention.

FIG. 1 shows a circulating hot water bath. The circulating hot water bath draws hot water in the bathtub 1 from a suction unit 3 disposed in the bathtub 1, and a filtering device 5 disposed inside the apparatus main body 4. The blowout unit 8 arranged in the bathtub 1 via the heating device 6 is configured to blow the air into the bathtub 1 again.

[0008] The suction unit 3 is fixed to the wall of the bathtub 1 by a suction plate 9, as shown in FIGS.
Hot water is sucked from a suction port 11 formed at the bottom of the housing 10, and the sucked hot water passes through a filter 12, a filtering material 13, and passes through a water absorption hose 15 connected to a delivery nozzle 14, into the inside of the apparatus main body 4. Filter device 5 arranged
It is constituted so that it may be sent to.

By the way, a water conduit 16 having a U-shaped cross section is formed from the upper part to the lower part of the housing 10 on the rear surface of the housing 10 to which the suction disk 9 is adsorbed.
6 has an opening 1 formed in the lower part of the housing 10.
8 to the suction port 11 and the headrace 1
A suction hole 17 called an orifice for restricting the amount of hot water and sucking the hot water is formed in an upper portion and an intermediate portion of the bath 6 so as to face the mounting surface of the bathtub 1. Further, a similar suction hole 19 is formed in the lower portion of the rear surface of the housing 10.

Next, the blow-out unit 8 is fixed to the wall surface of the bathtub 1 by an adsorber 20. As shown in FIG. 3, a blow-out pipe 22 is provided through the inside of the unit case 21 from the upper part to the front part. The upper end is connected to the water discharge hose 23, the hot water purified by the filtering device 5 inside the device main body 4 and heated by the heating device 6 is sent by the circulation pump 7,
A blow-out pipe 2 opened at the front of the unit case 21
It is configured to blow forward from the outlet 24 at the tip of the second.

An opening 25 is formed on the back surface of the unit case 21 to which the suction disk 20 is sucked. The opening 25 forms a small-diameter orifice formed by branching from the blowing pipe 22. The nozzle 26 is formed so as to blow hot water from the opening 25 toward the wall surface of the bathtub 1.

According to the circulation type hot water bath having the above configuration, when the circulation pump 7 operates, the hot water in the bathtub 1 is sucked from the suction port 11 of the suction unit 3. At this time, hot water on the back side of the suction unit 3 is sucked from the suction hole 17 of the water passage 16 formed on the back surface of the housing 10 and the suction hole 18 formed on the lower portion of the housing 10. Above suction hole 1
Numerals 7 and 18 are formed at the upper, middle and lower portions of the suction unit 3 for sucking evenly the stagnant water which is hard to flow between the back and the bathtub 1 from the entire back surface, and the back side of the suction unit. The hot water can be caused to flow to generate a water flow along the wall surface of the bathtub.

The hot water sucked in from the suction unit 3 is blown out from the blowing unit 8 into the bathtub 1 again through the filtering device 5 and the heating device 6 disposed inside the device main body 4 and is returned. At this time, the hot water purified and warmed inside the apparatus main body 4 is blown into the bathtub 1 from the tip of the blowing pipe 22, but a part of the hot water flows from the blowing nozzle 26 branched from the blowing pipe toward the wall surface of the bathtub 1. The hot water that has been blown out and is difficult to flow on the back side of the unit case 21 can be diffused along the wall surface of the bathtub 1, and the hot water on the back side of the blowout unit 8 can flow along the wall surface of the bathtub 1. A water flow can be generated.

As described above, when the circulation pump 7 operates, hot water is sucked from the suction port of the suction unit 3 and hot water on the back side of the suction unit 3 is sucked from the suction hole. Since a water flow can be generated in a narrow space and the stagnation of hot water can be eliminated, slime generated on the wall surface can be significantly reduced. The purified and warmed hot water is blown out from the tip of the blow-off pipe 22 of the blow-out unit 8, and is blown out from the blow-out nozzle 26 branching off from the blow-out pipe 22 to the back side of the blow-out unit 8. Therefore, a water flow can be generated in a narrow space between the back surface of the unit case 21 and the wall surface of the bathtub 1 and the stagnation of hot water can be eliminated, so that the generation of slime can be reliably suppressed.

Here, the number of the suction holes 17 may be appropriately provided according to the shape and size of the suction unit 3.

[0016]

According to the circulation type hot water bath of the present invention, the space formed by the suction unit and the bathtub wall surface where the hot water flows least in the bathtub and the blowout unit and the bathtub wall surface are linked to the operation of the circulation pump. A water flow can be generated in the space defined by the slime, slime generated on the wall surface can be significantly reduced, and a comfortable bathing environment can be provided to the bather.
