Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub apparatus and, more particularly, to a bathtub hot water purifier for purifying hot water in a bathtub by filtering or the like so as to keep it clean. It concerns the device. Recently, hot water in a bathtub has been sucked up by a circulation pump, dirt is filtered by a filtration device, heated by a heater, and further sterilized by ozone to constantly maintain a clean state at an appropriate temperature.
Bathtub hot water purifiers that can be used at any time of the day have been developed and widely used. [0003] As this bathtub hot water cleaning device, a device as shown in FIG. 5 is often used. In this device, various types of cleaning of hot water 2 in a bathtub 1 from a hot water suction pipe 3 by a circulation pump 6 are performed. The cleaning equipment is configured to suck up the cleaning equipment into the apparatus main body 4 in which the processing equipment is collectively stored, and to discharge the hot water after the cleaning processing from the fountain pipe 9 into the bathtub 1 again. [0004] At the end of the suction pipe 3, a pre-filter 10 using a sponge as a filter medium for removing large stains in the hot water is provided.
A jet nozzle 11 is provided at the tip of the jetting water device 4 for jetting the hot water after the cleaning process as a jet flow together with the air sucked in by the negative pressure formed by increasing the flow speed of the hot water in the ejector section. Has been deployed. [0005] The apparatus main body 5 includes a filtration tank 5 filled with various types of granular filter media such as activated carbon, barley stone, zeolite, etc., a heater 7 for maintaining hot water at an appropriate temperature, and a circulation pump 6 for forcibly circulating hot water. Are connected in series by a connecting pipe and provided, and one end of the water sucking pipe 3 is provided at a hot water inlet of the filtration tank 5,
One end of the hot water pipe 9 is connected to the discharge port of the circulation pump 7 to form a series cleaning circulation path for the hot water 2 in the bathtub 1. The apparatus main body 4 is provided with a filtration device equipped with a thread filter in addition to a filtration tank 5 filled with a particulate filter medium as a filtration device in order to increase the filtration capacity in the cleaning circuit. In some cases. [0007] An intake pipe 12 is connected to a jet nozzle 11 attached to the tip of the fountain pipe 9, and further has an ejector section for increasing the flow rate of the hot water to form a negative pressure in order to suck air from the intake pipe 12. Is provided. Further, an ozonizer 8 for forming ozone air for ozonizing the sucked air and sterilizing hot water is attached to the intake pipe 12. In the above apparatus, the hot water 2 in the bathtub 1 is sucked up from the hot water pipe 3 by the operation of the circulating pump 6 while the pre-filter 10 removes large dirt.
, And is filtered first in the filtration tank 5,
After that, the jet is jetted out again into the bathtub 1 from a jet nozzle attached to the tip of the hot water pipe 9. At this time, if the solenoid valve 13 provided at the intake port is open, air is sucked into the intake pipe 12, and a jet stream containing air is supplied from the jet nozzle 11 to the bathtub 1.
Is blown out into the so-called bubble bath, and when the ozonizer 8 is activated, the sucked air is ozonized,
Hot water 2 in bathtub 1 is ozone-sterilized. [0011] However, in the conventional apparatus, since the dirt in the form of colloidal particles dispersed in the bath cannot be filtered, there is a disadvantage that the hot water becomes cloudy if such dirt occurs. In particular, white turbidity was likely to occur in the early stage of the operation, particularly when the filter medium of the filtration device was not clogged, or immediately after the filter medium was washed or replaced. [0012] Bathtub dirt is not only general substances such as sand, mud, hair, and dirt, but also soaps, cosmetics, paints, and other substances attached to the body, secretions from the body, or tap water dissolved in the hot water. It is made of various materials, such as insolubles in water, and varies in size and nature. The large stains having a particle diameter of 1 micron or more are filtered by a sponge which is a filter material of a pre-filter, a granular filter material such as an activated stone, an activated carbon or a zeolite filled in a filtration tank, or a filtering ability of a wound filter. Very fine dirt having a particle diameter of 0.001 micron or less and dissolved dirt are removed by the adsorption power, ion exchange capacity, and the like of the particulate filter material filled in the filtration tank. However, in the conventional apparatus, as described above, the filtration ability of colloidal particles having a particle diameter of 0.001 to 1 micron formed by agglomeration of insoluble components causing clouding of the hot water is provided. Did not. [0015] This is because, when the filter device uses a fine precision filter medium capable of removing colloidal particle-like dirt, the filter medium becomes clogged immediately and the apparatus must be stopped each time to replace an expensive filter medium. This requires a lot of time and money, is very difficult to maintain, and gives great resistance to the flow of hot water, which reduces the amount of circulating hot water and reduces the ability of the equipment to clean. This is because only various types of ordinary filter media can be used. In the case where a coarse filter medium is used in the filter, the colloidal particle-like stains are completely removed immediately after the apparatus is installed or in a state where the filter is not clogged by washing or replacing the filter. Until the filter material could not be filtered, the filter material became dirty and clogged to some extent, and the filter material could be filtered, it was necessary to endure that the hot water became cloudy or to replace the hot water. The present invention solves the above-mentioned drawbacks of the prior art, and can maintain the same cleaning performance as before while filtering colloidal particle-like dirt using a precision filter medium, and also facilitates maintenance. It is an object of the present invention to provide a bathtub hot water purifier. That is, according to the present invention, hot water in a bathtub is pumped from a suction pipe and circulated through a cleaning pipe, and ordinary granular filter media such as activated carbon, barley stone and zeolite are used. The filled filter tank removes dirt of normal size with a particle size of 1 micron or more, sterilizes it with a sterilizer, heats it with a heater for cleaning, cleans it, and installs a jet attached to the end of a fountain pipe In the bath tub hot water purifying device for jetting out again as a jet stream to a bath tub, the squirt pipe is provided with a switching valve, and the switching valve is provided with a lid in a detachable sealed case in a colloidal form having a particle size of 1 micron or less. A sub-fountain tube equipped with a microfiltration device containing a membrane filter having a filtering ability for dirt is connected to the end of the jet nozzle by being connected to the negative pressure part of the jet nozzle mounted on the end of the spout tube. After the cleaning process is completed, the hot water flowing through the spout pipe is diverted to the sub-spout pipe, and the colloidal dirt having a particle size of 1 micron or less is filtered by a microfiltration device. A bath tub hot water purifier characterized by being ejected. The present invention is configured as described above. First, hot water in a bathtub is sucked from a water suction pipe by the action of a circulating pump and is subjected to a conventional cleaning treatment including filtration in the apparatus main body. After that, the water is circulated again through a series of cleaning pipes which are jetted from the fountain pipe to the bathtub again. At this time, since the sub-fountain pipe is branched in the middle of the hot-water pipe, a part of the hot water flowing into the hot-water pipe after the cleaning process in the main body of the cleaning device is finished flows toward the sub-hot-water pipe. The hot water that has flowed into the sub-water-absorbing tube is filtered by a precision filtration device provided with the filtering device of the main body of the cleaning device, and the colloidal particle-like dirt that cannot be filtered is jetted into the bathtub from the sub-fountain tube. . Further, since the microfiltration device is provided in the sub-spout pipe branched from the cleaning line in series as described above,
It can be installed at any position inside and outside the apparatus main body, and when the precision filter is clogged, the precision filter can be easily replaced at any time without stopping the operation of the apparatus main body. Further, when the tip of the sub-fountain pipe is connected to an ejector portion provided downstream of the sub-fountain pipe branch position of the spout pipe,
Even if the sub-spout pipe is provided with a microfiltration device that gives resistance to the flow of hot water, a considerable amount of hot water flows due to the suction force of the ejector unit, thereby enabling microfiltration. When an ejector section provided in the fountain pipe is used also as a jet nozzle attached to the tip, a jet stream is jetted into the bathtub to form a bubble bath, or ozonized air is jetted into the bathtub to sterilize the hot water. The same function as the conventional one can be provided. Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a first embodiment of the present invention. The basic structure is the same as that of the conventional example. In addition, a microfiltration device 16 is provided in the auxiliary jet pipe 15. Accordingly, the hot water 2 in the bathtub 1 is pumped up by the suction pipe 3 and removed into the apparatus main body 4 while removing large dirt by the pre-filter 10, where it is filtered by the filtration tank 5 and heated by the heater 7. When the switching valve 14 provided in the hot water pipe 9 is opened also in the direction of the auxiliary hot water pipe 15 from the rear hot water pipe 9, hot water also flows into the auxiliary hot water pipe 15 and flows through the precision filtration device 16. After the microfiltration, the water is jetted into the bathtub 1, whereby a part of the hot water pumped up from the bathtub 1 is microfiltered. If the switching valve 14 is closed in the direction of the sub-fountain pipe 15, the hot water does not flow into the sub-fountain pipe 15, but flows all through the spout pipe 9. The water is jetted into the bathtub 1 just by being filtered. If the switching valve 14 is closed in the direction of the spout pipe 9 and opened in the direction of the sub spout pipe 15, the hot water flows only through the sub spout pipe 15 and all the hot water is usually filtered in the filtration tank 5 of the apparatus body 4. Then, after being subjected to microfiltration by the microfiltration device 16 of the sub-fountain pipe 15, it is jetted into the bathtub 1. Therefore, when the turbidity of the hot water is severe, all the hot water can be subjected to microfiltration in addition to ordinary filtration by switching the switching valve 14. In the case where the precision filter of the precision filtration device 16 is clogged, if the switching valve 14 is closed in the direction of the sub-fountain pipe 15, the hot water does not flow to the sub-fountain pipe 15, but flows entirely through the spout pipe 9. As described above, the filter can be replaced while the cleaning process in the apparatus main body 4 is continued. An example of the structure of the microfiltration device 16 is as shown in FIG. 2. A cartridge case 17 having a water inlet at the bottom and an open top is mounted on a cartridge case 17 such as a membrane filter having a filtration capability of 1 micron or less in particle size. The filter 19 is loaded on a filter plate 18 having a countless number of water holes and fitted with a bottom surface and a predetermined space, and the upper opening of the cartridge case 17 in which the precision filter 19 is loaded is placed on the upper surface. This is a cartridge type filtration device closed by a detachable lid 20 having a water outlet. The precision device 16 constructed as described above
May be provided in the apparatus main body 4, but when the filter is provided outside the apparatus main body 4 by attaching it to the outer wall surface or the bathtub wall surface of the apparatus main body 4 via a suction cup, the precision filter 19 is clogged. It is easy and convenient to replace the case. FIG. 3 shows a second embodiment. In this embodiment, the auxiliary ejector pipe 15 has a distal end downstream of the sub-injection pipe 15 of the spouting pipe 9 in the end ejector section 2.
1 is an example of connection. In this example, similarly to the case of the first embodiment, by switching the switching valve 14, the three types of hot water flows of both the spout pipe 9 and the sub spout pipe 15, only the spout pipe 9, and only the sub spout pipe 15 are provided. And microfiltration can be performed by the appropriate microfiltration layer 16 according to the degree of cloudiness of the hot water. In this case, if the hot water is flowing through the hot water pipe 9, the hot water flows into the auxiliary hot water pipe 15 due to the suction action of the ejector unit 21, so that it becomes cheaper. FIG. 4 shows a third embodiment. In this embodiment, the jet nozzle 11 attached to the end of the fountain pipe 9 is also used as an ejector unit, and the intake air connected to the jet nozzle 11 is shown. This is an example in which the distal end of the sub-fountain pipe 15 is connected to the middle of the pipe 12 via the switching valve 22, and has the functions of the conventional bubble bath and ozone sterilization. In this embodiment, the switching valve 14 is switched in the same manner as in the first and second embodiments, and the switching valve 22 is closed in the direction of the solenoid valve 13 of the intake pipe 12 so that the jet nozzle 1 is closed.
By opening in one direction, it is possible to create three flows of hot water, both the fountain pipe 9 and the sub-fountain pipe 15, only the fountain pipe 9, and only the sub-fountain pipe 15, and an appropriate precision filtration layer according to the degree of cloudiness of the hot water. 16 can be used for microfiltration. The switching valve 14 is switched to open only in the direction of the blast pipe 9, the switching valve 22 is switched to close the direction of the auxiliary blast pipe 15 and to open the direction of the jet nozzle 11, and if the solenoid valve 13 is opened, the intake pipe 12 is opened. The jet flow into which the air is mixed is ejected from the jet nozzle 11 to form a bubble bath. Further, if the ozonizer 8 is operated while the air is being sucked from the suction pipe 12, ozone air is ejected from the jet nozzle 11 and the hot water in the bathtub 1 is discharged.
Can be sterilized. In the embodiment of the present invention, how much hot water flows through the sub-fountain pipe 15 was measured while comparing with the conventional example.
FIG. 6 shows the result. In FIG. 6, (a) and (b) show the embodiment, and (c) and (d) show the conventional example. It is a flow rate (l / min) in the side pipe, and in FIG. (C), the outside of the parentheses is the flow rate when the intake is taken from the intake pipe 12, and the parenthesis is the flow rate when the intake of the intake pipe 12 is stopped. . According to the result, the sub-water suction pipe 15 branched from the hot water pipe 9 and provided with the fine filtration device 16 is a conventional example in which the fine water filtration device 16 is provided directly on the hot water pipe 9 (FIG. 4D). It can be seen that a small amount of hot water flows, though slightly less than in case (1), and that microfiltration can be performed effectively. Further, the tip of the sub-fountain pipe 15 is
Although the amount of hot water flowing through the sub-fountain pipe 15 is not so much increased even if it is connected, the effect appears when the suction force of the ejector is increased or the microfiltration device 16 is clogged. Conceivable. Although not shown, if a flow sensor is provided in the sub-fountain pipe 15 according to a conventional method, clogging of the microfiltration device 16 can be automatically detected, and maintenance is facilitated. The present invention has the above-described structure and operation, and is provided with a fine filtration device provided in a sub-spout pipe branched from a spout pipe to cause colloidal particulate contamination causing cloudiness of the hot water. Can be effectively removed. In addition, when the microfiltration device is clogged, the filter can be replaced while continuing the normal cleaning process without stopping the device, so that maintenance is very easy. Further, if the switching valve is automatically switched in accordance with the turbidity of the hot water in the bathtub in order to flow hot water in the direction of the sub-fountain pipe for fine filtration, the filter of the fine filtering device is unnecessarily contaminated. Since maintenance is no longer required, maintenance becomes easier. As described above, the present invention provides an inexpensive bath tub hot water purifying apparatus which can perform microfiltration effectively and can bathe comfortably without causing white turbidity of the hot water, and does not require much labor and cost for maintenance. I do.
