Description

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. The present invention relates to a water suction device attached to a tip of a water suction pipe for sucking hot water from a bathtub for cleaning treatment. [0002] Recently, hot water in a bathtub is sucked up by a circulation pump, dirt is filtered by a filtration device, heated by a heater, and further sterilized by ozone, so that the hot water is kept constantly clean and can be bathed at any time for 24 hours. A bath water purifier has been developed and widely used. [0003] In a bathtub hot water cleaning device, since hot water contains a lot of large stains such as hair, the filter medium of the filtering device is clogged in a short period of time, or a device such as a circulating pump or a water flow sensor is used. It is preferable to attach a pre-filter for removing large dirt to the end of the water suction pipe in order to prevent the hair from getting broken due to the hair. Recently, a so-called bubble bath apparatus, which circulates hot water in a bath tub, increases the flow rate of the hot water by using a jet jetting apparatus, and jets the hot water again as a jet jet mixed with air, has also been widely used at home. I came. [0005] Therefore, in the bathtub hot water purifying device, a jet jetting device is provided as a hot water jetting device, and the hot water after cleaning is not simply jetted into the bathtub as a natural flow.
In many cases, the jets are jetted as jet jets so that a bubble bath can be enjoyed. FIG. 7 shows an example of such a bathtub hot water cleaning apparatus.
In this apparatus, a circulation pump 7 operates to draw up hot water 2 in a bathtub 1 with a hot water suction pipe 3 provided with a hot water suction apparatus 4 containing a pre-filter at the tip, and first removes dirt with a filtration apparatus 5. Filtration is performed, followed by heating by a heater 6 so as to maintain a predetermined temperature, and the heated hot water is jetted back into the bathtub 1 from a hot water jet device 9 provided with a jet nozzle at the tip of a hot water pipe 8. An intake pipe 10 provided with an electromagnetic valve 11 is attached to the fountain device 9.
The ozone tube 12 to which the ozonizer 4 and the ozonizer 13 are attached is branched. [0008] In the device configured as described above, the solenoid valve 1
When both 1 and 12 are closed, hot water is spouted from the fountain device 9 in a normal state, but when the solenoid valve 11 is open, air is sucked from the intake pipe 10 and air is mixed into the hot water. The jet jet is blown out and becomes a bubble bath. Further, when the electromagnetic valve 14 is open, hot water mixed with air ozonized by the ozonizer 13 is jetted out of the hot water device 9 into the bathtub 1 as a jet jet, and the hot water 2 is ozone sterilized. You. [0010] When the ozonized air is jetted into the bathtub by a fountain device and sterilized as described above, not only can the hot water be sterilized efficiently, but also the bathtub can be removed and mold can be prevented from forming on the wall of the bathroom. As a result, the function of the bathtub hot water cleaning device is further improved. Hot water suction device 4 in which the pre-filter is stored
It is conceivable that the fountain device provided with the jet nozzle and the jet nozzle are integrated with each other through a water suction pipe 4 as shown in FIG. A device has been developed in which a water jet device 9 provided with a jet nozzle is placed above, and a hot water device 4 containing a pre-filter is placed below, so that it can be detachably attached to a bathtub by suction cups 15 and 16. When the mechanism of the hot water and the hot water is set in this way,
Not only the mounting becomes easy, but also the vertical positional relationship between the hot water device 4 and the hot water device 9 can be freely adjusted by adjusting the length of the connecting part of the hot water pipe 3, so that the The positions of the jet nozzles were each set to the optimum position, which was convenient. Further, the water suction device 4 includes a main body case 17 having a water suction pipe connection port, a pre-filter case 18 in which a pre-filter is housed and fitted in the main body case 17, and a main body case in which the pre-filter case is fitted. Since the filter is made by detachably fitting the main body cover 19 having a water inlet covering the surface thereof, if the pre-filter becomes dirty, the main body cover 19 can be removed and this cleaning and replacement can be easily performed. Was. However, in the conventional water suction device, since the case and the cover are merely fitted together by fitting based on the dimensional tolerance, the dimensional tolerance is reduced or the unevenness is reduced. If the fittings are made to each other and tightly fitted, it will not be easy to remove them from each other. There is a drawback that it is unsuitable as a hot water suction device of a gasifier. That is, when the fitting is tight, it is not easy to remove the pre-filter case from the main body case, so that cleaning and replacement of the pre-filter, which must be performed frequently, are neglected. [0016] Then, the pre-filter is clogged with the attached dirt, and the amount of circulating hot water is reduced, and the cleaning effect is reduced. On the other hand, if the fitting is loose, the cover will come off naturally during use, and the hot water will be contaminated with the dirt that has been exposed on the pre-filter, or the pre-filter will need to be cleaned or replaced. When removing the pre-filter case with the cover covered, the cover often came off and the hot water was contaminated with the dirt attached to the pre-filter. The present invention solves the above-mentioned drawbacks of the prior art. Although the fitting can be easily performed, the fitting does not come off naturally once it is fitted, but can be easily removed when necessary. It is an object of the present invention to provide a hot water suction device. According to the present invention, hot water in a bathtub is pumped up by a circulation pump and circulated in a circulation path to perform filtration by a filter medium, heating by a heat retaining heater, sterilization by a sterilization device, and the like. A hot water suction device of a bathtub hot water cleaning device for applying and returning to a bathtub, a main body having a water suction pipe connection port connected to communicate with the circulation path, the front surface being opened to a predetermined depth. A case, a pre-filter for removing large dirt components, and a pre-filter having an opening and a depth for removably storing the pre-filter and having a flow opening for flowing hot water. A main body cover having a water suction port for closing an opening of the main body case. The main body case is fitted to the main body case and detached from the main body case by an operation. An actuating member that is free to move and the pre-filter case A main body cover having an operating member that fits with the housing and that allows the pre-filter case to be detachable by operation with respect to the locking portion of the pre-filter case. The release operation of the actuating member
The problem could be solved by a hot water suction device of a bathtub hot water cleaning device in which the filter case containing the main body cover and the prefilter was integrally removed. The present invention is constructed as described above, and the parts making up the water suction device such as the case and the cover are forcibly disengaged so that one of the concave and convex portions forming the fitting releases the fitting. The fitting is performed by a forced release fitting mechanism formed as a forcedly actuated fitting member that is moved. When such a fitting mechanism is used, parts can be easily assembled by natural fitting as in the case of assembly by normal fitting, and there is a concern that the parts will come off naturally after being fitted once. There is no firmly fitted and assembled. However, in the case where it is desired to disassemble despite the fact that it is assembled in such a firm fitting, the fitting can be easily disengaged and disengaged simply by moving the forcibly operating member constituting the fitting. Can be decomposed into [0023] For this reason, dirt easily adheres, and maintenance of the hot water suction device that frequently repeats disassembly and assembly can be extremely easily performed. Further, if the pre-filter case accommodating at least the pre-filter is fitted to the main body cover by a forced operation fitting mechanism, the pre-filter case can be used during the cleaning process or for cleaning or replacing the pre-filter. When removing the case from the case, the case in which the body cover naturally comes off and the dirty pre-filter is exposed and the hot water is contaminated never occurs. Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of the water suction device, and FIG. 2 is a side sectional view thereof. The basic configuration will be described first with reference to these drawings. Reference numeral 20 denotes a main body case having an opening on the front surface and a predetermined depth, and a water suction tube connection port 21 for connecting a water suction tube is provided on the upper surface of the main body case 20; A suction cup 22 for attachment is attached. Reference numeral 23 denotes a pre-filter case having an open front surface and a predetermined depth. The rear surface of the pre-filter case 23 is provided with a predetermined gap from the rear surface to support the pre-filter in a state in which hot water flows well. In addition, vertical and horizontal ribs 24 and a number of bosses 25 are erected, and a number of hot water circulation holes 26 are provided. Reference numeral 27 denotes a pre-filter such as a sponge, and 28 denotes a main body cover having an open rear surface. A water suction port 29 is provided below the front surface of the main body cover 28, and the outer periphery of the back side is formed by attaching the outer periphery of the pre-filter 27 to the front side. A pressing rib 30 is provided for pressing from above. In the water suction device composed of the above-described components, the pre-filter 27 is first stored in the pre-filter case 23, and then the pre-filter case 23 storing the pre-filter 27 is fitted into the main body cover 28. Cover 2 fitted with pre-filter case 23
8 is fitted to the main body case 20 attached to a predetermined position of the bathtub by the suction cup 22 to complete the assembly. In such a water-absorbing device, as shown by the arrow in FIG. 2, the hot water in the bath tub is first sucked from the hot-water inlet 29 of the main body cover 28, and large dirt is removed by the pre-filter 27 of the pre-filter case 23. Filtered, pre-filter 2
7 is pressed by the holding rib 30 of the main body cover 28 and the portion surrounding the outer circumference of the rib 24 of the pre-filter case 23 so that no water leaks. The water enters the water suction pipe 20 and flows to the water suction pipe connected to the water suction pipe connection port 21. Next, a mechanism for fitting the main body cover 28 to the main body case 20 is shown in a horizontal sectional view in FIG. 3, and a view in which a pre-filter case is fitted to the main body cover in FIG. It will be described based on. Numeral 31 denotes a forcibly operating claw as a forcibly operating member which forms a forcibly operating fitting mechanism mounted on the upper portion of the left and right side surfaces of the main body cover 28. The foot, which is a claw portion 32 to be fitted, has a T-shape with a head including a button portion 33 and a slide boss portion 34 extending from the button portion 33 for forcibly operating the claw. ing. Two guide ribs 36 are set up in parallel on the back surface of the main body cover 28, and the forcibly operating claws 31 are fitted into the button holes 33 at the same time as the guide ribs 3 at the same time.
The slide boss 34 is attached to the main body cover 28 while slidably fitting the tip of the slide boss 34 therebetween. At this time, a compression spring 35 is fitted to the slide boss 34, and the tip of the compression spring 35 is abutted against the end of the guide rib 36. As a result, the claws 32 are pressed against the inner surface of the main body cover 28. A fitting groove 37 is provided on the inner surface of the main body case 20 at a position where the claw 32 of the forcibly operating claw 31 contacts. Therefore, when the main body cover 28 is fitted into the main body case 20, the forcibly operating claws 31 of the main body cover 28
Is fitted into the fitting groove 37 of the main body case 20. At this time, since the forcibly operating claw 31 is pushed outward by the force of the compression spring 35, the claw 32 is fitted with the fitting groove 37. They fit tightly and never come off naturally. When the main body cover 28 is to be removed from the main body case 20, when the button portion 33 of the forced operation claw 31 is pressed inward, the claw portion 32 is separated from the fitting groove 37, so that it can be easily removed. Note that two downward projections 38 protrude from the lower end surface of the main body cover 28, and two holes 39 for fitting the projections 38 are provided on the lower end surface of the main body case 20. When the operating claw 31 and the fitting groove 37 are fitted as described above after fitting the hole 39 with the hole 39, the main body case 20 and the main body cover 28 are more firmly fitted. Next, a mechanism for fitting the main body cover 28 and the pre-filter case 23 will be described with reference to the exploded perspective views of FIGS. Fitting projections 40 and 41 protrude from the upper and lower surfaces of the filter case 23, and a fitting hole 42 into which the fitting projection 40 is fitted is provided on the lower surface of the main body cover 28. Further, a forced operation fitting hole plate 43 is attached to the upper side of the back surface of the filter case 23. The forced operation fitting hole plate 43 is formed by bending a plate material having a spring property such as stainless steel. The horizontal operating plate portion 44 is vertically oriented in opposite directions about a vertical fitting hole plate portion 45 provided with a fitting hole 46, and a mounting plate portion not shown in the drawing. Is provided. The forced operation fitting hole plate 43 has the operating plate portion 44 facing upward, and the fitting hole 46 of the fitting hole plate portion 45 is formed.

In order to fit the main body cover 28 and the pre-filter case 23 with such a configuration of the fitting mechanism, the pre-filter case 23 is fitted to the main body cover 28 by the fitting projection 40 on the lower surface and the fitting hole on the lower surface. 42, the fitting projection 41 on the upper surface is forcibly operated.
And fits into the fitting hole 46 while pushing in the upper direction. In this case, since the forced operation fitting hole plate 43 is made of a plate material having a spring property such as stainless steel as described above, the fitting hole plate portion 45 is pushed by the fitting protrusion 41 and the upper surface is formed. After being bent in the direction, the projection 41 returns to the original vertical state at the moment when the projection 41 is fitted into the fitting hole 46, so that the fitting projection 41 and the fitting hole 46 are firmly fitted to each other and cannot be naturally removed. Become. To remove the pre-filter case 23 from the main body cover 28 by pulling out the fitting projection 41 tightly fitted from the fitting hole 46, the forced operation fitting hole plate 4 is required.
The operation plate part 44 of No. 3 may be pushed downward. When the operation plate portion 44 of the forced operation fitting hole plate 43 is pushed downward, the fitting fitting hole plate portion 45 rotates upward, so that the fitting projection 41 is pushed out from the fitting hole 46 and is easily inserted. Are released from each other, and then the pre-filter case 23
Can be easily removed from the body cover 28 by pulling the fitting projection 40 out of the fitting hole 42 by pulling it upward. It is preferable that the operating plate portion 44 be slightly upward in order to further increase the power when the operating plate portion 44 is pressed downward and the fitting hole plate portion 45 is rotated. The present invention has the above-described structure and operation, and is manufactured by fitting a main body case, a pre-filter case, a main body cover and the like constituting a hot water suction device by a forced release fitting mechanism. ing. In this forcible release fitting mechanism, one of the projections, such as claws and projections, and the recesses, such as grooves, holes, etc., which form the fitting, is forcibly moved to release the fitting. It is formed as a member, and in such a fitting, although the fitting is easy, once it is fitted, it does not come off naturally, but on the other hand, it can be easily performed simply by pushing the forced-acting fitting member The fitting is released. With such a fitting, frequent removal and installation of the pre-filter case for cleaning and replacement of the pre-filter does not impose any burden, and furthermore, the hot water is not contaminated by the dirt attached to the pre-filter. The cover covering the pre-filter case is a water-absorbing device that does not come off naturally during operation of the apparatus or when the pre-filter case is removed. As a result, since the maintenance of the hot water absorption device becomes extremely easy, the dirt is removed and the clean state is constantly maintained, the amount of hot water circulating due to the clogging of the filter is reduced and the hot water cleaning device is cleaned. Your ability will not be reduced.
