Description

The present invention relates to a bath device.

(Prior Art) The water level of a bathtub in a conventional bath device for home use or the like fluctuates depending on the person entering the bath device.

(Problems to be Solved by the Invention) Therefore, when entering the bathtub at a high water level, hot water overflows from the upper part of the bathtub, and the overflowed hot water is wasted. Therefore, when pouring hot water into the bathtub, it is necessary to pay attention to the water level, and if this is not done, there is waste. Also, the water level depends on the physique, and the water level drops after a person with a large physique takes a bath. Therefore, the next person to bathe had to add hot water or settle for a lower water level.

According to the present invention, a rectangular upper peripheral member of a bathtub body is provided with a gutter-shaped collection groove for collecting hot water overflowing from the upper part of the bathtub body, and the hot water collected from the gutter-shaped collection groove is returned to the bathtub. It is an object of the present invention to solve the above-mentioned problems by adopting a configuration of refluxing.

By the way, when the gutter-shaped recovery groove is formed in the upper peripheral member of the bathtub, if the width of the upper peripheral member is widened for this reason, the installation space of the bathtub becomes large, and there is a hindrance to the entrance and exit of the bather. Therefore, the width cannot be expanded so much. Therefore, the conventional bathtub a as shown in FIG.
With this configuration, the width of the gutter-shaped recovery groove b cannot be made wide, and the amount of hot water flowing through the gutter-shaped recovery groove b is limited. There is also such a disadvantage that it overflows to the outside of the upper peripheral member c.

The present invention aims to prevent such inconveniences in addition to the above-mentioned objects.

(Means for Solving the Problem) The means for solving the above-mentioned problems will be described with reference to the drawings showing an embodiment. In the bath device of the present invention, the rectangular upper peripheral member 3 of the bath body 2 is provided.

In a bath apparatus constituted by a reflux path 12 for circulating hot water in the hot water storage means 10 to the bathtub 1 by a pump 11, the bathtub body 2 is arranged around the vertical axis with respect to the upper peripheral member 3. While being rotated, the upper peripheral member 3 is arranged so as to be offset to one widthwise portion w side of the upper peripheral member 3, and the gutter-shaped recovery groove 4 and the other widthwise portion w ′ of the upper peripheral member 3,
Along the widthwise portion w ', the longitudinal portions 1, 1'are formed, and the wide portion 7 of the gutter-shaped recovery groove 4 is formed in the wide portion of the upper peripheral member 3 formed by the rotation and movement. The wide portion 7 is provided with a hot water outlet 9 to the hot water storage means 10, and the wide ridge portion of the upper peripheral member 3 is provided with a bather entrance / exit portion 8 not forming the gutter-shaped recovery groove 4. Is.

In the above structure, the upper edge 5 of the bathtub body 2 may be configured to have all the portions corresponding to the gutter-shaped recovery groove 4 of the upper peripheral member 3 configured to be low to form the overflow portion 6, and It is also possible to form a portion of the peripheral member 3 corresponding to the gutter-shaped recovery groove 4 to be low to form the overflow portion 6. Further, the heights of the overflow portions 6 can be set to the same height, and the portion corresponding to the wide portion 7 of the gutter-shaped recovery groove 4 can be made lower than the other portions, and the like can be appropriately changed.

(Operation) In the above structure, when a person enters the bathtub body 2, the hot water inside overflows from the overflow portion 6 and flows into the gutter-shaped recovery groove 4 formed in the upper peripheral member 3. . The hot water that has flowed into the gutter-shaped recovery groove 4 flows through the hot water outlet 9 and the hot water storage means 10
Will be introduced to. Next, the hot water in the hot water storage means 10 flows through the reflux path 12 by the pump 11, and the hot water outflow portion 13 for reflux.

The water level in the bathtub 1 can be maintained at a high level at all times, and the overflowing water level can be maintained, and when a person enters the bathtub 1, it is possible to take a very satisfying bath.

Particularly, in the present invention, the upper peripheral member formed by the arrangement and rotation of the main body of the bath 1 relative to the upper peripheral member 3 in the trough-shaped recovery groove 4 for collecting the hot water overflowing from the main body 2 of the bath. Since the wide part 7 is configured to correspond to the wide part of 3,
This portion improves the flow of the overflowed hot water, so that the overflow from the upper peripheral member 3 can be prevented. Further, since the bather enters and leaves the bathtub main body portion 2 at the entrance and exit portion 8 formed in the width ridge portion of the upper peripheral member 3, it is easy to enter and exit.

Here, in the upper edge 5 of the bathtub body 2, all the portions corresponding to the gutter-shaped recovery groove 4 of the upper peripheral member 3 can be configured to be low, and all of this can be configured as the overflow portion 6, or the upper peripheral edge. A part of the portion of the member 3 corresponding to the trough-shaped recovery groove 4 may be configured to have a low height, and only a part thereof may be configured to serve as the overflow portion 6. The heights of the overflow portions 6 are all the same, and if the portion a corresponding to the wide portion 4 of the gutter-shaped recovery groove is configured to be lower than the other portions b, the amount of overflow hot water from the corresponding portion a. Is larger than the others, and it is possible to better prevent the above-mentioned overflow from the trough-shaped recovery groove 4 due to overflow from the other portion b.

(Example) Next, the Example of this invention is described about FIGS.

In the figure, reference numeral 1 is a bathtub, 2 is its main body portion, and 3 is its rectangular upper peripheral member 3. In this bathtub 1, the bathtub body portion 2 is rotated around the vertical axis with respect to the upper peripheral member 3 and is arranged so as to be offset to one width direction portion w side of the upper peripheral member 3. I am configuring. The rotation angle is, for example, about 5 ° to 10 °, and the moving distance can be appropriately moved to such an extent that the narrowest portion of the widthwise portion w is not too narrow. Thus, the gutter-shaped recovery groove 4 is formed in the other widthwise portion w'of the upper peripheral member 3 and in the longitudinal portions 1, 1'continuously with this widthwise portion w '.
A wide portion 7 of the gutter-shaped recovery groove 4 is formed in a wide portion of the upper peripheral member 3 formed by the rotation and movement, and a hot water outlet 9 to the hot water storage means 10 is formed in the wide portion 7. A bather entrance / exit portion 8 that does not form the gutter-shaped recovery groove 4 is formed in the width ridge portion of the upper peripheral member 3. Further, the gutter-shaped recovery groove 4 is appropriately inclined in the direction of the outlet 9. In the configuration shown in FIGS. 1 and 2, the upper edge 5 of the bath body 2 is
Of the upper peripheral member 3, all the portions corresponding to the gutter-shaped recovery groove 4 are configured to be low to form an overflow portion 6, and the height of the overflow portion 6 corresponds to the wide portion 7 of the gutter-shaped recovery groove 4. The portion a to be formed is configured to be lower than the other portions b. Further, in the configuration shown in FIG. 4, the upper edge 5 of the bathtub body 2 has a part of the upper peripheral member 3 corresponding to the gutter-shaped recovery groove 4 formed low to form an overflow portion 6.

A bath serving as a hot water storage means 10 is installed below the outlet 9, and a hot water in the hot water storage means 10 is provided with a reflux path 12 for returning the hot water to the bathtub 1 by a pump 11 to form a bath apparatus. As described above, the hot water storage means 10 is configured as a tank installed below the outlet 9, but it may be configured as a tank spaced apart from the bathtub 1. In this case, the outlet 9 and A pipe may be provided between the hot water storage means 10.

At the downstream end of the reflux path 12, reflux water outlets 13a and 13b to the bath 1 are provided, and the reflux fluid outlets 13a and 13b are provided at the upper portion and the side wall of the bath 1. There is. A bubble-mixing ejection nozzle utilizing an ejector action can be formed in the reflux hot water outflow portion 13b of the side wall portion.

Further, in the embodiment, in addition to the pump 11, the reheating heat exchange section 14 and the filtration section 15 are configured in the reflux path 12. The additional heating heat exchange unit 14 has a configuration in which a heat exchanger 16 and a burner 17 for heating the heat exchanger 16 are provided on the downstream side of the pump 11. Further, in the reflux path 12, a backwashing path 18 of the filtering section 15 is branched, and the backwashing path 18 is provided with switching valves 19a and 19b on the upstream side and the downstream side of the filtering section 15, and on the upstream side. Selector port 20 of switching valve 19a
The drainage path 21 is connected to a, and the backwash water path 23 to the backwash water source 22 is branched and connected to the selection port 20b of the switching valve 19b on the downstream side.

In the above configuration, when a person enters the bathtub body 2 and the hot water therein overflows from the overflow portion 6 into the trough-shaped collection groove 4, the overflowed hot water flows through the trough-shaped collection groove 4 into the hot water outlet 9 And flows into the tank as the hot water storage means 10 from the hot water outlet 9. Next, the hot water in the hot water storage means 10 flows through the reflux path 12 by the pump 11, passes through the filtration part 15 and the heat exchanger 16 for additional heating, and then to the reflux hot water outflow part 13b or the upper part provided on the side wall of the bathtub 1. It recirculates back into the bathtub 1 from the provided hot water outflow portion 13a. In such reflux, the reflux from the reflux hot water outlet 13a at the upper portion makes the flow of the refluxed hot water reminiscent of a hot spring bath, which can further enhance the feeling of satisfaction, and the reflux provided on the side wall portion. Hot water outlet 13b
In the recirculation from the above, by forming the bubble generating means here, the satisfaction at the time of bathing can be further enhanced.

The above reflux control can be easily performed by providing the overflow water detection means 24 in the hot water storage means 10.
For example, when hot water is introduced into the hot water storage means 10 and is detected by the detection means 24, it is possible to detect overflow water, that is, it is possible to detect that a person has entered the bathtub 1, and based on such detection, a predetermined value is determined. The reflux control can be automatically performed. Further, such recirculation control can be performed by detecting a lid (not shown) of the bathtub with an optical sensor or the like, and the recirculation can be controlled not to be conducted when the lid is closed.

When the temperature of the hot water in the bathtub 1 is lowered in the above bathing, the reheating can be performed by operating the burner 17 and raising the temperature by the heat exchanger 16 as needed at the time of reflux.

By the way, since foreign matter such as dirt and hair entering the bathtub 1 when bathing is light, it easily floats upward, and therefore overflows from the upper edge of the bathtub 1 together with the collecting means to the hot water storage means 1
0 is introduced into the hot water storage means 10 and then flows through the reflux path 12 together with the hot water which is refluxed from the hot water storage means 10. In the embodiment, however, since the reflux path 12 is provided with the filter section 15, these foreign matters are filtered by the filter section 15.
It is removed from the hot water flowing back into the bath 1. Therefore, the hot water in the bathtub 1 can be maintained in a clear state. The foreign matter collected in the filtering unit 15 may be removed from the filtering unit 15 by, for example, replacing the filtering material of the filtering unit 15 every appropriate period, or as described above, the reflux path 12 and the backwashing path of the filtering unit 15 may be removed. 1
8 may be branched, and may be configured to be removed from the filtration unit 15 by backwashing after being used for an appropriate period. In the above-mentioned backwash passage 18, the backwash water from the backwash water passage is supplied to the switching valve 1 in the state where the reflux is not performed.
After passing through the filtering section 15 in the direction opposite to the reflux direction via 9b, and draining from the drainage path 21 via the switching valve 19a, foreign matter is removed by backwashing and the filter medium is regenerated. In addition to tap water, hot water in the bathtub 1 can be used as the backwash water. The hot water lost from the reflux system due to the first use of hot water or the use of hot water in the bathtub 1 may be appropriately replenished by a hot water supply device or the like. In addition, in the above-mentioned embodiment, in addition to the pump 11, the reheating heat exchanging section 14 and the filtering section 15 are configured in the reflux path 12, but these may be omitted, for example, in the bathtub 1. The hot water may be reheated by installing a bath kettle in the bathtub 1, and the foreign matter can be removed by the same method as in the normal bathtub 1.

(Effect of the invention) As described above, according to the present invention, hot water is overflowed from the upper edge of the bathtub when bathing, and the overflowed hot water is returned to the bathtub again through the return path. Therefore, it is possible to maintain a high water level in the bathtub and to maintain the water level at which the water overflows without paying attention to the bathtub. The water level in the bathtub is not affected by the physique, and the disadvantage that the water level is not lowered after a person with a large physique takes a bath does not occur. Particularly, the present invention has a gutter-shaped collection groove for collecting hot water overflowing from the bathtub body portion, and a wide portion corresponding to the wide portion of the upper peripheral member formed by the rotation and movement arrangement of the bath body with respect to the upper peripheral member. Since the part is configured, the flow of the hot water overflowing is improved by this part, and therefore, it is possible to prevent the overflow from the upper peripheral member to the outside, and the bather can configure the entrance / exit part configured in the width ridge part of the upper peripheral member. Since the bathtub body is moved in and out, there is an effect that it is easy to go in and out.
