Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a bath device.

(Conventional technology) Bathing not only removes dirt from the body, but also relieves the fatigue of the day, relieves stress, and contributes to improved health, so in recent years, improvements have been made to bath equipment. There are also bathtubs that can emit air bubbles into the bathtub.

For example, JP-A-56-13943 or JP-A-Sho.
The device disclosed in Publication No. 55-103855 etc. blows out air bubbles by supplying air from an air pump or the like to a bubble blowing section installed in a bathtub, and Japanese Patent Application Laid-Open No. 1983-
Publication No. 122665, Japanese Utility Model Application No. 63-146633, or Japanese Utility Model Application No. 64-39731 has a structure in which hot water in the bathtub is circulated through a reflux path equipped with a pump, and from this reflux path to the injection part into the bathtub. This constitutes a means for mixing air bubbles.

Incidentally, the water level of bathtubs in conventional bathing devices for home use, including these baths, rises and falls depending on the person who enters the bathtub.

(Problem to be solved by the invention) In a conventional bath device that circulates hot water in a bathtub through a reflux path equipped with a pump, in order to mix and inject air bubbles as described above, the injection part is heated inside the bathtub. It is located below the water level, so you cannot enjoy the flowing hot water like you would in a bath at a hot spring resort.

Furthermore, in conventional bath devices, if a person enters a bathtub with a high water level, hot water overflows from the top of the bathtub, and this overflowing hot water is wasted. Therefore, when filling a bathtub with hot water, it is necessary to pay attention to the water level, and if this is not done, there will be waste. The water level also depended on the person's body size, and the water level would drop after a larger person took a bath, so the next person taking a bath had to add more water or settle for a lower water level.

The present invention aims to solve the above problems.

(Means for Solving the Problems) Means for solving the above-mentioned problems will be explained with reference to drawings showing embodiments.The bath device of the present invention is configured such that hot water inside the bath can be flooded from the top. A bathtub 1, a recovery means 2 for recovering the overflowing hot water, a hot water storage means 3 for storing the recovered hot water, and a reflux path 5 for circulating the hot water in the hot water storage means 3 back to the bathtub 1 by a pump 4. The reflux hot water outlet portions 7a and 7b connected to the downstream end of the reflux path 5 are provided at the upper and side wall portions of the bathtub 1, and the reflux hot water outlet portion 7b of the side wall portion constitutes a bubble mixing means. In addition, a bubble generating means 13 is provided for blowing out bubbles from the bottom of the bathtub 1.

(Function) In the above configuration, when a person enters the bathtub 1 and the hot water inside overflows from the top, the overflowing hot water is introduced from the recovery means 2 to the hot water storage means 3. Next, the hot water in this hot water storage means 3 is passed through a reflux path 5 by a pump 4.
The hot water flows back into the bathtub 1 from the reflux hot water outlet portions 7a and 7b. Therefore, overflowing hot water is not wasted. Therefore, in the present invention, the water level in the bathtub 1 can be maintained at a high level at all times so that it does not overflow, and when a person enters the bathtub 1, the water overflows, making it possible to take a very satisfying bath. can.

The hot water can be returned to the bathtub by selecting either of the hot water flow outflow parts 7a, 7b, etc. provided on the top and side walls, or through both at the same time. In the return flow from the hot water outlet 7a, the flow of the returned hot water is reminiscent of a bath at a hot spring resort, which can further enhance the feeling of satisfaction.
In the reflux from the reflux hot water outlet 7b provided on the side wall, the bubble mixing means configured here can further enhance the satisfaction during bathing. When the bubble generating means 13 is operated together with the above-mentioned reflux of hot water, bubbles can be generated from the bottom of the bathtub 1, thereby making it possible to take a bubble bath and further enhancing the above-mentioned sense of satisfaction.

(Example) Next, embodiments of the present invention will be described with reference to the drawings.

Figure 1 is a system explanatory diagram of the overall configuration of the present invention, Figure 2
The figure is an explanatory perspective view of the bathtub part. In this figure, reference numeral 1 is a bathtub, and this bathtub 1 is constructed so that hot water can overflow from the top, and this overflowing hot water can be collected. A recovery means 2, a hot water storage means 3 for storing the recovered hot water, and a reflux path 5 for refluxing the hot water in the hot water storage means 3 to the bathtub 1 by a pump 4.
A bath apparatus is constructed by providing a bubble generating means 13 for blowing out bubbles from the bottom of the bathtub 1.

The recovery means 2 is configured as a gutter-like portion having an outlet 6 to the hot water storage means 3 around the bathtub 1.
In addition, a receiver (not shown) may be provided at the bottom of the bathtub 1. Also, bathtub 1
The overflowing point is only a part of the upper edge of the bathtub 1, from which the water overflows into the gutter-like part and is introduced into the hot water storage means 3 through the outlet 6.
In addition, the bathtub 1 may be constructed so that water overflows from the entire upper edge, or a water overflow port (not shown) may be provided at the top of the bathtub 1. Next, the hot water storage means 3 is configured as a tank installed below the outlet 6 formed in the gutter-shaped part in the illustrated example, but it can also be configured as a tank installed separately from the bathtub 1. In this case, piping may be provided between the recovery means 2 and the hot water storage means 3.

At the downstream end of the reflux path 5, reflux hot water outlets 7a, 7b are provided for flowing back into the bathtub 1, and these reflux hot water outlets 7a, 7b are provided at the top and side wall portions of the bathtub 1. A bubble mixing and spouting nozzle 8 utilizing an ejector action is provided in the reflux hot water outlet 7b of this side wall. Reference numeral 9 is an air pipe that takes in air to be mixed. Further, in the reflux path 5, on the downstream side of the pump 4, a reheating section 12 is configured which includes a heat exchanger 10 and a burner 11 for heating the heat exchanger 10. Reference numeral 13 denotes a bubble generating device, and an air pipe 14 from this device 13 is connected to a blowhole 15 formed at the bottom of the bathtub 1.

Reference numeral C denotes an operating section that controls the reflux, bubble mixing, and bubble generation operations by controlling the regulating valve 18 and the like, and the operating section C is installed in the upper part of the bathtub 1.

In the above configuration, when a person enters the bathtub 1 and the hot water inside overflows from the top, the overflowing hot water is introduced into the tank as the hot water storage means 3 from the gutter-shaped part as the recovery means 2. Next, this hot water storage means 3
The hot water inside flows through the reflux path 5 by the pump 4, passes through the heat exchanger 10 in sequence, and returns to the bathtub 1 from the reflux hot water outlet 7b provided on the side wall of the bathtub 1 or the reflux hot water outlet 7a provided at the top. reflux within. At this time, for the reflux from the reflux hot water outflow part 7b provided on the side wall, by operating the operation part C, you can adjust whether or not bubbles are mixed, the mixing amount, and whether the reflux hot water flows out from either the left or right side in the figure. It is possible to control selection of the section 7b, etc.

The above control of the reflux can be easily performed by providing the overflow detection means 16 in the hot water storage means 3. For example, by introducing hot water into the hot water storage means 3 and detecting it by the detection means 3, it is possible to detect overflow, that is, to detect that a person has entered the bathtub 1, and based on this detection, a predetermined reflux control can be performed automatically. Moreover, such control of the reflux can be performed in combination with a sensor that detects the lid of the bathtub 1. In other words, when this sensor detects the lid, reflux can be prevented.

When the bubble generating means 13 is operated simultaneously with the above reflux operation or independently, bubbles can be generated from the bottom of the bathtub 1, and a bubble bath can thus be performed, further increasing the satisfaction described above. can.

If the temperature of the water in the bathtub 1 drops during the above bathing, the burner 11 may be turned on as necessary to reflux the water.
Reheating can be performed by operating the heat exchanger 10 to raise the temperature.

By the way, foreign matter such as dirt and hair that gets into the bathtub 1 when taking a bath is light and therefore tends to float upwards.Therefore, along with water overflowing from the upper part of the bathtub 1, it is introduced from the collection means 2 into the hot water storage means 3, and then the hot water is stored in the hot water storage means 3. The hot water flows through the reflux path 5 together with the hot water refluxing from within the means 3. Therefore, if a filtration device or the like is installed at an appropriate location in the reflux path 5, the above-mentioned foreign substances can be removed there.

Note that the hot water lost from the reflux system due to the initial supply of hot water into the bathtub 1 or the use of hot water may be replenished as appropriate using the hot water supply device 17 or the like. Further, in the above embodiment, in addition to the pump 4, the reheating section 12 is configured in the reflux path 5, but these can be omitted. For example, reheating the hot water in the bathtub 1 is This may be done by installing a bath pot in the bathtub 1, and the removal of foreign substances can be done in the same way as in a normal bathtub.

(Effects of the invention) As described above, the present invention has a structure in which hot water overflows from the top of the bathtub when taking a bath, and the overflowing hot water is returned to the bathtub via the reflux path.
This overflowing hot water is not wasted, so you can raise the water level in the bathtub without paying special attention to it.
The water level can be maintained at a level that will not overflow, and the water overflows when a person enters the bathtub, making it possible to take a very satisfying bath.The water level in the bathtub is not affected by body size, so it is suitable for people with large builds. This has the effect that the inconvenience of the water level dropping after taking a bath does not occur. In particular, with the present invention, hot water can be returned to the bathtub by selecting either the hot water outlet provided on the top or the side wall, or through both at the same time. When the hot water flows back from the hot water outflow part, the flow of hot water is reminiscent of a bath at a hot spring resort, further increasing the feeling of satisfaction. By using the bubble mixing means configured as above and by operating the bubble generating means appropriately, bubble bathing can be performed from the bottom, which has the effect of further increasing the satisfaction during bathing.
