Description

  The present invention relates to a purification device that efficiently removes dust floating on the water surface in a bathtub, and relates to a bathtub that prevents dust floating on the water surface in the bathtub from adhering to a side wall in the bathtub.

  Various proposals have been made regarding a purification device for removing dust floating on the water surface in a bathtub. In these conventional purification apparatuses, a skimmer provided with a hole in the side wall of the bathtub (for example, see Patent Document 1), a water supply port floating in the bathtub (for example, see Patent Document 2), and a bathtub There is one that causes hot water to overflow from the upper part of the side wall (for example, see Patent Document 3).

  Hereinafter, a conventional purification device will be described. In the conventional example of Patent Document 1, as shown in FIG. 10, hot water in the bathtub 1 and the skimmer 14 is sucked by the circulation unit 16, filtered by a filter in the circulation unit 16, and then circulated in the bathtub 1. ing. Further, if the amount of hot water in the skimmer 14 decreases, air enters the circulation pump in the circulation unit 16 and becomes a problem. Therefore, when the amount of hot water decreases, the hot water in the bathtub 1 circulates in the skimmer 14. ing.

  In this conventional example, since the amount of hot water is not controlled, it has also been proposed that the water inlets in the skimmer 14 are arranged in two upper and lower stages (not shown) so as to cope with changes in the water level.

  Since the amount of hot water is not controlled in the conventional example according to Patent Document 2, the water supply port is floated in the bathtub, the hot water is sucked from the water supply port with a circulation pump, filtered, and returned to the bathtub.

On the other hand, the conventional example by patent document 3 is controlling the amount of hot water. In this conventional example, a water level sensor and a water replenisher are attached to the recovery tank, and when the water level drops, water is supplied from the water replenisher and hot water in the recovery tank is circulated to the bathtub with a circulation pump. It overflows from the upper part of the side wall and is collected in the collection layer.

  In the conventional purification device, it is necessary to provide two water inlets or float the water supply port in the skimmer in order to cope with changes in the amount of hot water, and even if two water inlets are provided in the skimmer. If the amount of hot water changed more than that, the effect could not be demonstrated.

  In addition, since dust is floating on the surface of the water, it can be collected in these skimmers and water supply ports, but it is difficult to efficiently suck and capture the filter, and when the circulation pump is stopped, these skimmers Inside, there was a problem that dust floating on the water surface in the water supply port flows back into the bathtub.

  In the conventional purification device that controls the amount of hot water and overflows the hot water in the bathtub from the upper part of the bathtub side wall to efficiently collect and filter the dust floating on the water surface, it overflows from the upper part of the bathtub side wall. However, there is a problem that it can be used in a public bath, but cannot be used in a small bathtub in a general household.

  Further, the conventional technique for preventing dirt from adhering to the vicinity of the water surface of the side wall in the bathtub is mainly the above-described purification device, that is, the removal of dust floating on the water surface. However, it is difficult to catch all the dust floating on the water surface before adhering to the side wall, and it has been impossible to prevent the adhering.

  According to the first aspect of the present invention, in order to solve these problems, in the first aspect of the present invention, an inlet provided inside the bathtub or provided with a hole in the side wall of the bathtub and an overflow from the bathtub through the inlet A water storage tank having a lower water surface than the bathtub, and a circulation device for circulating the hot water of the water storage tank to the bathtub without being filled with hot water, depending on the amount of hot water of the water storage tank Supply water or hot water.

  Furthermore, in the position below the predetermined water level of the bathtub at the time of bathing, an open part other than the inlet is not provided outside the bathtub, or for controlling the inflow of hot water from the inlet to the water storage tank. An on-off valve is provided, or at the time of bathing, the circulation speed of the circulation device is increased, and a large amount of hot water flowing into the water storage tank is circulated in the bathtub.

  According to a second aspect of the present invention, an air supply port or a water supply port is provided in the vicinity of the side wall in the bathtub or the side wall of the bottom, and gas is sent from the air supply port to the hot water in the bathtub, or the water supply Remove hot water in the bathtub excluding the surface layer from the mouth or hot water in the bathtub with a purifier, filter, etc., and then remove the dust floating on the water surface directly or on the bathtub side wall without crossing the center of the bathtub with a circulation device The water is supplied toward the water surface near the side wall.

  According to the first aspect of the present invention, water supply or hot water supply is performed according to the amount of hot water in the water storage tank having a stable water surface, so that even if the water surface of the bathtub is undulated, it is not affected, and the amount of hot water can always be kept optimal with high accuracy. Therefore, it is not necessary to provide two water inlets or to float the water inlet.

  In addition, the circulation device circulates the hot water in the water storage tank to the bathtub without filling the inlet with hot water, so the hot water in the bathtub overflows into a water storage tank with a lower water surface than the bathtub, and waste floating on the water surface Can be collected and captured in the water tank efficiently, and even if the circulation device is stopped, the dust floating on the water surface does not flow back into the bathtub.

  Further, according to the first aspect of the present invention, no opening other than the inlet is provided outside the bathtub at a position below a predetermined water level of the bathtub at the time of bathing, or the inflow of hot water from the inlet to the water storage tank is controlled. When opening or closing the bath, the circulation speed of the circulator is increased, and a large amount of hot water flowing into the water tank is circulated to the bathtub. Can be provided. And when bathing, hot water can be stored in the bathtub up to a position higher than the inlet without overflowing to the outside, so a large amount of extra hot water is unnecessary.

  In the second aspect of the invention, an air supply port or a water supply port is provided near the side wall in the bathtub or the side wall of the bottom, and the gas is sent from the air supply port to the hot water in the bathtub, so that bubbles are convected upward into the hot water near the side wall. Wake up. As a result, the hot water inside the bathtub without dust floating on the water surface is supplied to the water surface near the side wall, so that the dust floating on the water surface does not adhere to the side wall in the bathtub.

  Or, after removing the dust-free hot water floating on the water surface from the water inlet, that is, the hot water in the bathtub excluding the surface layer, or the hot water in the bathtub with the purifier, filter, etc. Since the water is supplied to the water surface near the side wall along the side wall of the bathtub, hot water without dust floating on the water surface is supplied to the water surface near the side wall, and the dust floating on the water surface adheres to the side wall in the bathtub. There is nothing to do.

  In addition, the supply of hot water without dust that floats on the water surface is directed toward the water surface without crossing the central part of the bathtub, so it is not affected by the human body during bathing, and the water surface can be waved or moved up and down. Not affected. Furthermore, if it supplies toward the water surface from the bottom, since the water surface will flow in the direction away from the side wall, the effect is greater.

  The best mode for carrying out the present invention is that in the first invention, the water level in the water tank in which the water surface is stable is detected and water or hot water is supplied, so that the water level in the bathtub is always kept optimal and the circulation device is used. Water from the water tank is sent to the bathtub, and the water in the bathtub is filled with hot water from the inlet provided inside the bathtub or in the side wall of the bathtub. Overflow to the tank.

  In order to prevent hot water from overflowing to the outside during bathing, do not provide an open part other than the inlet at the position below the predetermined water level of the bathtub at the time of bathing, or from the inlet to the reservoir An on-off valve is provided for controlling the inflow of hot water into the water, or the circulation speed of the circulation device is increased at the time of bathing, and a large amount of hot water flowing into the water storage tank is circulated to the bathtub.

  In the second invention, an air supply port or a water supply port is provided in the vicinity of the side wall in the bathtub or the side wall of the bottom, and by sending gas from the air supply port to the hot water in the bathtub, air bubbles are directed upward to the hot water in the vicinity of the side wall. The hot water inside the bathtub without any dust floating on the water surface is supplied to the water surface near the side wall.

  Or, after removing the hot water without dust floating on the water surface from the water supply port, that is, hot water in the bathtub excluding the surface layer, or hot water in the bath with a purifier, a filter, etc. By supplying directly to the water surface in the vicinity of the side wall without crossing the central portion of the bathtub, the hot water free from dust floating on the water surface is supplied to the water surface in the vicinity of the side wall. .

  A detailed description will be given below with reference to the drawings.

  (Embodiment 1) An embodiment according to the first invention will be described with reference to the drawings. FIG. 1 shows an embodiment according to the first invention. The inflow port 2 is provided by making a hole in the side wall of the bathtub 1, and the open portion 21 at the upper part of the water storage tank 3 is provided at a height higher than that in consideration of the rise in the water level during bathing. . A ball tap 5 is attached to the water storage tank 3, and the operation of the ball tap 5 is such that when the water level is lowered, the float is lowered and the valve is opened to supply hot water. The circulation device 4 circulates hot water from the water storage tank 3 to the bathtub 1.

  In this embodiment, first, hot water supply, that is, hot water supply is started. Since there is no hot water in the water storage tank 3, the float of the ball tap 5 is lowered and hot water is supplied. The circulation device 4 is driven after a while so that the bubbles are not involved, and the hot water in the water storage tank 3 is circulated in the bathtub 1.

  In this embodiment, since the hot water supply speed from the ball tap 5 is set faster than the circulation speed of the circulation device 4, the water surface in the water tank 3 rises over time, and the float of the ball tap 5 rises. Stop. In the meantime, since the circulation device 4 continues to send hot water in the water storage tank 3 to the bathtub 1, the water surface in the water storage tank 3 is lowered, the ball tap 5 is lowered, and hot water supply is resumed.

  In this way, the water surface in the bathtub 1 rises, and finally the hot water overflows from the inlet 2. Then, the hot water supply from the ball tap 5 is stopped, the amount of hot water is kept optimal, and the hot water always overflows from the inlet 2 to the water storage tank 3.

  Next, when a person takes a bath, a large amount of hot water flows into the water storage tank 3, but the volume of the water storage tank 3 is not so large, the water in the water storage tank 3 is filled and the water surface of the bathtub 1 exceeds the inlet 2. Rise.

  However, since the open part 21 of the water storage tank 3 is provided at a height higher than that in consideration of the rise of the water level during bathing, hot water does not overflow outside. In addition, hot water always flows from the bathtub 1 toward the water storage tank 3 through the inlet 2 by the circulation device 4, so there is no fear of backflow. Although the opening portion 21 is provided in this embodiment, there is no problem if no opening portion is provided other than the inlet 2 as shown in FIG.

  Next, when a person goes out of the bathtub 1, the water surface of the bathtub 1 falls below the inflow port 2, and the overflow disappears. However, the water tank 3 has hot water up to the height of the inlet 2, and the hot water in the water tank 3 is continuously sent to the bathtub 1 by the circulation device 4. Then, the water surface of the bathtub 1 rises and returns to circulation due to overflow, and the dust floating on the water surface is efficiently collected and captured in the water tank 3.

  In the present embodiment, when a person leaves the bathtub 1, a reverse flow occurs. However, if a check valve is provided in the inflow path to the water storage tank, the problem can be solved. Even if the upper part of the water storage tank 3 is made U-shaped as shown in FIG. 1, it is possible to prevent the backflow of dust floating on the water surface. I can do it. Also, if the amount of hot water is reduced by taking it out with a person or using it, the overflow from the bathtub 1 is eliminated, the water level of the water storage tank 3 is lowered, and hot water is discharged from the ball tap 5 as in the case of the hot water mentioned above. Is returned to the optimal amount of water again.

  Therefore, in order to efficiently collect and capture dust floating on the water surface, it is most desirable to use an overflow that collects and captures the water surface together. If the circulation device 4 of this embodiment exceeds the amount of hot water flowing into the water storage tank 3 through the inflow port 2 and continues to send the hot water in the water storage tank 3 to the bathtub 1, the inflow port 2 is filled with hot water. Further, even if the water level in the water storage tank 3 is lowered, hot water is continuously supplied from the ball taps 5 so that the water surface is submerged in the hot water as shown in FIG. It is not possible to collect and capture garbage floating on the ground.

  Therefore, in the first invention, it is necessary to sufficiently consider the capacity of the circulation device, the design of the inlet and the piping from the inlet to the water tank, including the intermittent operation of the circulation device. In addition, the hot water in the water storage tank must be circulated to the bathtub without the water surface of the bathtub rising and the inlet filled with hot water. Furthermore, it is most desirable that an airway can be secured without being filled with hot water in the piping from the inlet to the water storage tank.

  Other embodiments according to the first invention will be described with reference to FIGS. In FIG. 3, the automatic opening / closing valve 7 is attached to the inlet 2, and the water level gauge 6 is attached to the bathtub 1, and the opening 21 is provided at a position below the water surface of the bathtub 1. The automatic open / close valve 7 uses buoyancy, and when a person bathes and the water level rises, the valve closes accordingly and hot water is prevented from overflowing from the open portion 21 of the water tank 3. is there.

  When the automatic opening / closing valve 7 is closed, hot water does not flow to the water storage tank 3 through the inlet 2. If the circulation device 4 continues to operate in this state, as described above, hot water is continuously supplied from the ball taps 5 even if the water level in the water storage tank 3 is lowered, so that a large amount of hot water continues to be sent to the bathtub 1. It will be.

  Therefore, the water level meter 6 is for confirming whether or not the bathing is in progress, and for stopping the circulation device 4 by sending a signal during bathing. In FIG. 3, the water level meter 6 is provided in the bathtub 1, but the present invention is not limited to this, and it is also possible to manually stop the circulation device during bathing.

  In FIG. 4, a second circulating device 41 is attached to the water tank 3 in addition to the water level gauge 6 and the circulating device 4, and the opening 21 is provided at a position below the water surface of the bathtub 1. The water level meter 6 is designed to move the second circulation device 41 when the water level of the water storage tank 3 rises above a predetermined water level and to stop when the water level is below the predetermined water level. Normally, since the water surface of the water storage tank 3 is below a predetermined water level, only the circulation device 4 is operated and hot water is circulated.

  When a person bathes, a large amount of hot water flows into the water storage tank 3 through the inflow port 2, and the water level of the water storage tank 3 rises above a predetermined water level. Then, the second circulation device 41 starts operation, and together with the circulation device 4, the same amount of hot water as the amount flowing into the water storage tank 3 is not overflowed from the open portion 21 of the water storage tank 3 without being overflowed. Cycle to 1.

  In FIG. 4, two circulation devices are used. However, it is also possible to use one high-performance circulation device, change the interval of intermittent operation, and switch the circulation speed. Further, without providing the water level gauge 6, the circulation speed of the circulation device can be manually switched in accordance with bathing.

  In FIG. 5, the inflow port 2 is provided inside the bathtub 1, and hot water from the circulation device 4 is also circulated without making a hole in the bathtub 1. Moreover, the opening part 21 is provided in the bathtub 1, and it is designed so that the dust drifting in the hot water can be captured by the filter 8 provided separately.

  Thus, by providing the inlet in the bathtub, it becomes possible to attach the apparatus to the bathtub later as a unit. In addition, even if an opening is provided in the bathtub so that dust drifting in the hot water can be captured, there is no problem if attention is paid to the design of the size of the opening and the capacity of the circulation device.

  In the above embodiment, hot water is supplied only from the ball tap 5 in the water storage tank 3, but is not limited to this as long as the hot water supply is performed by detecting the amount of hot water in the water storage tank. There is no problem with hot water supply. As for the initial hot water beam, it is possible to turn the faucet and supply water directly to the bathtub. Furthermore, even if water is supplied instead of hot water, there is no problem as long as it has a separate function for hot water. Even in an example in which a filter is not used, it is desirable that the filter be provided between the inlet and the circulation device in order to capture dust drifting in the hot water.

  (Embodiment 2) Next, an embodiment according to the second invention will be described with reference to the drawings. In FIG. 7, an air supply port 9 is provided at the bottom near the side wall of the bathtub 1, and air is supplied from the air supply device 10.

  The air then becomes bubbles 17 and rises toward the surface of the water, causing upward convection in the hot water near the side wall of the bathtub, supplying hot water inside the bathtub free of dust floating on the water surface to the water surface near the side wall. Yes.

  In FIG. 8, a water supply port 11 is provided on the side wall of the bathtub 1. The circulation device 4 supplies hot water in the lower part of the bathtub free of dust floating on the water surface from the water supply port 11 toward the water surface near the side wall.

  As described above, in the second aspect of the invention, hot water without dust floating on the water surface is supplied to the water surface near the side wall, so that dust floating on the water surface does not adhere to the side wall in the bathtub.

  In addition, the supply of hot water without dust that floats on the water surface is directed toward the water surface without crossing the central part of the bathtub, so it is not affected by the human body during bathing, and the water surface can be waved or moved up and down. Not affected. Furthermore, if it supplies toward the water surface from the bottom, since the water surface will flow in the direction away from the side wall, the effect is greater.

  The number and arrangement of the air inlets and water inlets should be determined in consideration of the shape and size of the bathtub, the flow rate of hot water or gas to be supplied, etc. It is also possible to supply the hot water in the bathtub or the hot water in the bathtub to the water surface in the vicinity of the side wall after removing the dust floating on the water surface with a purifier or a filter.

  (Embodiment 3) It is difficult to capture all dust floating on the water surface before adhering to the side wall in the bathtub, and the second invention is more effective than the first invention in terms of preventing adhesion. . However, in the second invention, it is necessary to keep driving as long as there is dust floating on the water surface. FIG. 9 is made in consideration of the above, and shows an embodiment in which the first and second inventions are combined.

  In this embodiment, a separate timer (not shown) is provided, and the circulation device 4 is driven in conjunction with the water level gauge 6. The operation is such that when the water level in the water storage tank 3 exceeds a predetermined value, the circulation device 4 starts to operate, and when the water level falls below the predetermined water level again, a timer is activated to stop the circulation device 4 after a predetermined time. is there.

  When a person bathes in the bathtub 1 where hot water filling is completed, the hot water flows through the inflow port 2, so that the water level of the water storage tank 3 rises above a predetermined value. The water level meter 6 senses this and starts the operation of the circulation device 4.

  The circulation device 4 filters the hot water in the water storage tank 3 together with the hot water flowing in from the bottom of the bathtub 1 through the filter 8 and circulates the hot water from the water supply port 11 to the bathtub 1. And the filtered hot water supplied from the water supply port 11 keeps preventing the dust which floats on the water surface which the person brought in from adhering to a bathtub side wall as Example 2 demonstrated.

  When a person leaves the bathtub 1 for a while, the water level in the water storage tank 3 becomes lower than a predetermined water level, and the timer is activated. During this time, the circulation device 4 continues to operate, supplying hot water from the water supply port 11, while preventing the dust floating on the water surface from adhering to the side wall, overflowing the water storage tank 3 from the inlet 2, Collect and capture. At the same time, the dust drifting in the hot water contained in the hot water flowing from the bottom of the bathtub 1 is also filtered by the filter 8. Then, after a predetermined time, collection and capture of dust floating on the water surface is completed, and the timer stops the operation of the circulation device 4.

  As described above, when the first and second inventions are combined, it is possible to prevent the dust floating on the water surface from adhering to the side wall without continuing to operate the circulation device. Furthermore, if a timer is used, it can be operated efficiently and the electricity bill can be saved significantly.

  In the first embodiment, the water storage tank is not provided with a drain valve. However, as in this embodiment, the drain valve 12 is used to discharge dust floating on the water surface, and the drain valve 13 is opened when the water tank is cleaned. It is desirable to provide a drain valve.
