Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to an overflow bathtub device.

[0002]

[Prior Art]

 Hot water in the bathtub gradually becomes polluted by bathing, so it is desirable to replace with fresh hot water after each bathing in order to have a comfortable bathing. However, in reality, from the economical point of view, the current situation is that hot water is repeatedly used several times. Therefore, various measures have been taken to suppress the contamination of hot water in the bathtub.For example, when the hot water in the bathtub is returned to the water heater to perform additional heating, it is supplied to the filter. Means for filtering hot water and supplying it again into the bath can be mentioned. By the way, recently, a so-called overflow bathtub device has been commercialized, which is provided with an auxiliary bathtub for supplying hot water to make it overflow and collecting the overflowing hot water. In such an overflow bath device, when hot water overflows, the hot water overflows and accumulates in the auxiliary bath, so the auxiliary bath water level switch is turned on, and the pump is operated to collect the overflow hot water and supply the water heater. It is filtered by the filter provided in the room and is returned to the bath again.

[0003]

[Problems to be solved by the device]

 However, when bathing, the circulation of hot water in the bathtub decreases, and hot water and dust and scales floating on the surface of the hot water are difficult to move to the auxiliary bath side and are difficult to filter. Also, as hot water overflowing with dust, scales, etc. flows into the auxiliary bath and the hot water accumulates in the auxiliary bath, the space inside the auxiliary bath becomes smaller, and the air becomes air bubbles. It comes out from the small hole of the lid member. At this time, dust, scales, etc. in the warm water flow backwards from the auxiliary bath together with air bubbles and accumulate on the auxiliary bath and the hot water surface of the bathtub, and the dust, scales, etc. become unsightly to the eyes. The amount of water introduced into the filter is reduced, the filtration and purification of hot water is significantly impaired, and comfortable bathing may not be possible at all. The present invention has been made to solve such a problem.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a hot water supply device connected to a bathtub through a hot water circulation pipe, and an auxiliary bathtub for collecting overflow hot water. In an afro bathtub device that is connected to a water vessel by a return pipe for collecting hot water, the outflow pipe that constitutes the hot water circulation pipe is branched to provide a plurality of hot water jets in the bathtub. is there. Further, according to the present invention, a water heater is connected to the bathtub through a hot water circulation pipe, and an auxiliary bath for collecting overflowing hot water is provided, and the auxiliary bath and the water heater collect hot water. In an overflow bathtub device that is connected by a return pipe for cooling, the outflow pipe that constitutes the hot water circulation pipe is branched so that the hot water outlet in the bathtub faces the bathtub wall side where the auxiliary bathtub is installed and the auxiliary bathtub. It is characterized in that it is provided on the wall side of the bathtub and these hot water jets are provided at different installation heights. Further, according to the present invention, a filter is arranged at the opening of the auxiliary bath, and a partition plate is formed above the filter so that the bathtub is on the back, and the upper side of the partition plate is at the edge of the auxiliary bath. It is characterized in that it is formed so as to be close to each other, and a gap is provided between the edge portion of the auxiliary bath and the partition plate.

[0005]

[Action]

 If hot water is constantly circulated between the water heater and the bathtub even while taking a bath, the hot water spouted in the bathtub will be agitated in the bathtub, and dust, scale, etc. will not stagnant in the hot water. Easily flows into the auxiliary bath.

[0006]

【Example】

 Next, an overflow bathtub device according to the present invention will be described in detail below with reference to an embodiment. In FIG. 1, reference numeral 1 denotes an overflow bathtub apparatus according to the present invention. The overflow bathtub apparatus 1 has a bathtub 2, a water heater 3, a reboiler return pipe 5 and a reboiler pipe constituting a hot water circulation pipe 4. They are connected and connected via a pipe 6. The overflow bathtub apparatus 1 has a bathtub 2 provided with an auxiliary bathtub for supplying hot water to make it overflow and collecting the overflowed hot water, that is, a mini tank 7. From the bottom of the mini tank 7, a mini tank return pipe 8 for collecting hot water is connected to the water heater 3 described above.

The reheating pipe 6 is branched into two pipes in the middle, and a hot water outlet 9 a provided on the bathtub wall side where the minitank 7 is provided and on the bathtub wall side opposite to the minitank 7, 9b is connected. Of the hot water jets 9a and 9b, the hot water jet 9a provided on the bathtub wall side facing the mini tank 7 is installed at a higher position than the hot water jet 9b provided with the mini tank 7. . In addition to the hot water outlets 9a and 9b, further outlets may be provided.

In the overflow bathtub apparatus 1 having the above-described configuration, if hot water is constantly circulated between the water heater 3 and the bathtub 1 even during bathing, the hot water jetted into the bathtub 1 will be It is agitated inside and does not stagnant. That is, the hot water that has been ejected from the hot water outlets 9a and 9b flows upward from the bottom portion of the bathtub 1, reaches the mini tank 7 side, and moves toward the bottom portion again. For this reason, dust, scales, etc. can easily overflow with warm water without flowing into the warm water and flow into the mini tank 7.

As described above, dust, scales and the like existing in the warm water easily overflow with the warm water without stagnating in the warm water due to the warm water flow formed by the warm water jets 9a and 9b, and the mini tank 7 Since it can be removed by flowing it into the water heater, the warm water can be kept clear in combination with the action of the filter (not shown) of the water heater 3 and a comfortable bath can be performed.

In addition, although not shown, a filter may be arranged in the opening 7 in the mini tank 7 of the overflow bath tub apparatus 1 according to the present invention. Further, a partition plate having the bathtub 2 as a back may be formed so as to project above the filter. By doing so, dust, scales, etc. are filtered in the filter, and only relatively clear warm water is circulated to the water heater 3, so that the life of the filter can be extended. Moreover, even if dust, scale, etc. are accumulated in the filter, the filter is covered by the partition plate, so that the filter is not noticeable during bathing and does not cause discomfort.

[0011]

[Effect of the device]

 Since the present invention is as described above, the hot water flow formed by the hot water jet can easily overflow with hot water without flowing into the hot water and flow into the auxiliary bath for removal.
