Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water circulating bath device which is continuously operated for 24 hours to keep the hot water in a bath clear by a fine filtering member and to keep the hot water temperature at a constant value. Further, the present invention relates to a hot water circulation type bathtub device having a single spout, in which a suction port and a jet port for circulating hot water in the bathtub are attached to a single through hole opened in the bathtub.

2. Description of the Related Art A hot-water circulating bathtub device that can be bathed for 24 hours has been developed. This device is provided with a heating means for keeping the temperature of the hot water constant and a clarification filtering member for clarifying the hot water. This device is a clarification filter member that continuously filters hot water all day long to keep it clean. The clarification filter member removes foreign matters such as dust. Furthermore, the clarification filter member
By the action of bacteria that inhabit here, components such as sweat that are dissolved in warm water are decomposed and the warm water is kept clear. For this reason, this device can be bathed at any time without changing the hot water in the bathtub. For this reason, it is extremely convenient to use and has a high water-saving effect.

In the hot water circulation type bath device of this structure, it is necessary to circulate the hot water in the bath between the fining filter member and the heating means. For this reason, it is necessary to open a hot water inlet and a hot water outlet in the bath. The hot water sucked from the suction port is filtered by the clarification filter member, heated to a preset temperature by the heating means, and discharged from the jet port to the bath. Two through holes are opened in the bath to provide an inlet and an outlet. The installation in which two through holes are opened and the suction port and the injection port are connected to each other has a drawback that the installation work is troublesome. This is because two through holes are opened and piped in both the bathtub and the bathroom wall.

This problem can be solved by forming the suction port and the injection port into a single unit. A technique for forming the suction port and the injection port into a single unit 5 is disclosed, for example, in Japanese Utility Model Laid-Open No. 59-62.
No. 443 publication. As shown in FIG. 1, the apparatus described in this publication has a suction port 1 and an injection port 2 as a single unit 5 arranged in a bath 6. The suction port 1 is connected to a suction pipe 3, and the injection port 2 is connected to a discharge pipe 4.

[0005]

The apparatus shown in FIG. 1 has a feature that the structure of the suction port 1 and the injection port 2 can be simplified because the suction port 1 and the injection port 2 are a single unit 5. .
However, in the apparatus shown in this figure, two through holes 7 are opened in the bath 6 in order to penetrate the pipe connected to the suction port 1 and the injection port 2 into the bath 6. For this reason, it is not possible to simplify the installation work for mounting the bathtub 6. Further, the single unit 5 of this structure has a drawback that it is difficult to keep the hot water in the bath 6 clear, which is extremely important for the hot water circulating bath apparatus. In particular, it is difficult to effectively remove floating matters such as dirt and hair floating on the hot water surface. It is a suction port by submerging suspended matter in warm water.
Because it cannot be inhaled from.

Further, this structure can also be used for an apparatus for keeping hot water in a clear state by continuously operating for 24 hours. However, a device utilizing this structure reduces the activity of bacteria inhabiting the clarification filter member and reduces the action of clarifying warm water. This is because in the device using this structure, the jet port 2 is located at the bottom of the bathtub 6, and the jetted hot water cannot sufficiently bubble the water surface. If there is little contact with air on the water surface, oxygen in the air cannot be efficiently dissolved in warm water, dissolved oxygen in warm water is reduced, and the activity of bacteria is reduced. For this reason, it is necessary to increase the amount of the clarification filtration member for keeping the warm water clear and increase the circulating amount of the hot water, which increases the manufacturing cost and the running cost.

The present invention was further developed with the object of eliminating this drawback, and an important object of the present invention is to simplify the installation work and to keep hot water efficiently and clearly. The present invention provides a hot water circulating bathtub device.

EFFECTS OF THE INVENTION The hot-water circulating bathtub device with a single spout according to the present invention has a feature that the installation work on the bathtub can be remarkably simplified. That is, the hot water circulation type bath device of the present invention is provided with both a suction pipe and a discharge pipe in one through hole opened in the bath, and a gate separation unit is connected to the suction pipe and the discharge pipe of the through hole, This is because the gate separation unit opens the suction port and the injection port in the bath.

Furthermore, in the hot water circulating bathtub apparatus with a single sprue according to the present invention, a sprue separation unit is connected to one through hole,
With this gate separation unit, the suction port and the injection port are vertically separated. The suction port is arranged in the lower part of the gate separation unit, and the injection port is arranged in the upper part of the gate separation unit. Therefore, the intake port inhales hot water from the bottom of the bath, and the injection port injects the clarified warm water to the upper part. The hot water vigorously jetted near the hot water surface in the upper part of the bathtub vigorously agitates the hot water near the hot water surface, and efficiently sinks floating matters such as dirt and hair floating on the hot water surface into the hot water. The suspended matter floats due to the surface tension of water, but when stirred, it is forcibly drawn into the water and settles. The suspended matter settling in the warm water is removed from the warm water by being removed by the primary filter and the clarification filtering member. Therefore, the hot water circulation bath device of the present invention has a feature that the suspended matter on the hot water surface can be efficiently collected and the hot water can be kept in a clean state.

Furthermore, the hot water which is vigorously stirred on the water surface is
It violently moves at the interface with air to efficiently dissolve oxygen contained in the air. Therefore, the hot water circulation bath device of the present invention can increase the amount of dissolved oxygen in hot water, and oxygen is supplied to the bacteria inhabiting the clarification filtration member. Bacteria are regenerated by the supplemented oxygen and efficiently decompose organic substances contained in warm water. That is, the activity of bacteria is improved and the action of clarifying warm water is improved. This is extremely important for this type of wear. This is because you can bathe in warm water that is very clean and transparent. An apparatus in which the activity of bacteria decreases is required to increase the circulation amount of hot water or increase the capacity of the clarification filtration member. In order to increase the circulation amount, it is necessary to use a large-capacity circulation pump, which increases the running cost. Further, if the circulation pump and the clarification filtration member are made large, the manufacturing cost becomes high.

The hot water circulation type bathtub apparatus of the present invention can be installed by providing one through hole in the bathtub,
It realizes an important feature for this kind of device that can efficiently remove foreign matters such as suspended matter contained in hot water and keep bacteria warm and keep hot water extremely clean.
