DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circulating and purifying apparatus having a single-port type suction / discharge unit in a small-sized tub water circulating / purifying system for home use.

[0002]

2. Description of the Related Art There has been proposed a conventional small household bath water circulation / purification unit which is installed in a bathroom. However, it is too large for a small bathroom so that it is installed outdoors. Alternatively, even when installed indoors, it may be installed outside the bathroom, and an externally installed type of circulating purification device has been proposed. In this case, in order to move the hot water in the bathtub to the circulating cleaning unit, it is necessary to pass through a distribution pipe which is provided so as to penetrate a bathroom wall and furthermore, an outer wall of a house. Therefore, it is connected to each of the discharge nozzle and the suction port mounted through the side wall of the bathtub by a communication pipe, and the hot water in the bathtub is suctioned and purified from the pre-filter installed in front of the suction port. In addition, the purified hot water is discharged from the discharge nozzle into the bathtub. Furthermore, in the case where an air pipe for mixing air into hot water to form a jet jet is connected, an air check valve also needs to be provided at an appropriate position on the communication pipe outside the bathtub. When the air check valve was built in the wall of the bathroom, the maintenance and inspection had to be performed by peeling off the wall plate and the like.

If the air check valve is installed far away from the air outlet and close to the circulating cleaning unit and breaks down, hot water accumulates at that position in the pipe, so that the air of the jet stream is sucked. There is also an obstacle that the negative pressure is reduced and the air is exhausted.
Therefore, in the conventional embodiment, the check and repair / replacement of the air check valve are performed by removing the wall plate and the like, and the work is complicated and time-consuming. Met.

1 is provided, and a flat cylindrical suction port 32 extending outward from a part of the outer periphery is provided.

A discharge port 1 provided at the back of the unit body 7
An air intake section 33 is provided at the end of 5. An air pipe 58 is connected to the air intake section,
Further, the communication pipe is connected to the circulation cleaning device 2. A tubular mounting portion 35 for mounting an air check valve 34 is inserted into the air intake portion 33. As shown in FIGS. 2 and 5, a security ring 3 is provided on the outer periphery of the cylindrical mounting portion.
6, which prevents water from entering the air pipe from the outer periphery when inserted into the cylindrical hole of the air intake section 33.

The air check valve 34 has a valve chamber 37 surrounded by a wall, and a wall 38 at the boundary between the valve chamber and the cylindrical mounting portion 35 has a flexible hole formed in the center. A support shaft 40 of an umbrella-shaped valve 39 made of synthetic resin is inserted, and an air through hole 41 is provided at an appropriate position.

The air check valve 34 is provided with a throttle section 42 integral with the valve chamber 37 at a position before the air check valve. The throttle portion includes a hollow portion 43, an air discharge port 44 formed outside the hollow portion, an air chamber 45 communicating with the air discharge port, and an outer peripheral portion 46.
The hollow portion 43 is formed with a tapered portion 47 tapering toward the bathtub side and a discharge port 48 of a straight pipe.

A nozzle packing 57 is attached to the outer peripheral portion near the front end of the bath. When the pre-filter case 19 is inserted, the hot water in the bathtub is circulated and cleaned by the nozzle packing 57 through a path other than the pre-filter 23. The confidentiality is maintained so as not to enter the unit 2.

Since the present invention is configured as described above, it operates as follows. That is, when the circulating cleaning device 2 is operated by operating the control panel 5, the hot water in the bathtub 1 is sucked from the suction port 32 of the pre-filter unit 19 as shown in FIG. It is passed through a filter 23 loaded in the unit case 22 and is filtered in advance therefrom. As shown by an arrow A from a suction connection port 17 formed at the rear of the unit main body 7) Then, it is circulated and cleaned through the communication pipe 3a. It is sent into the device 2.

The hot water sent into the circulating cleaning device passes through the filtration section of the main filter, where it is further filtered, and subsequently heated to a set temperature by a heating device. The hot water flows from the circulation cleaning unit 2 through the communication pipe 3b to the discharge connection port 18 formed at the rear of the unit body 7. When the hot water enters from the unit body 7 of the suction / discharge unit 4 and is discharged into the bathtub 1, the hot water is supplied to the suction / discharge unit 4 mounted in the bathtub 1
As shown by the arrow B in FIG. 2, the liquid is discharged from the unit main body 7 through the throttle section 42 into the bathtub 1 through the nozzle 53.

The maintenance is performed as follows. The suction / discharge unit 4 provided on the side wall 6 of the bathtub 1 can first remove the pre-filter unit 19 from the bathtub side as shown in FIG.
Is loaded, the case cover 21 is removed, the pre-filter 23 is taken out, and the pre-filter can be washed. After the pre-filter unit is removed, the nozzle 53 is screwed into the unit body 7 of the suction / discharge unit 4.
It can be easily removed from the bathtub by loosening the screw. Further, since the air check valve 34 and the throttle 42 mounted in the outlet 15 of the unit body 7 are integrated as shown in FIG. 5, when checking the throttle 42 or the air check valve 34, a bathtub is required. Both can be simultaneously removed from the side through the discharge port 15, and inspection is performed with the both removed.

[0023]

Since the present invention has the above-described structure and operation, at the time of assembling, the throttle portion is firstly mounted in the discharge port 15 from the bathtub side, and then the nozzle 57 is mounted in the unit body 7. Then, the pre-filter unit 19 can be mounted. At the time of maintenance, the pre-filter unit 19, the nozzle 57, the throttle section 42, and the air check valve 34 are integrally configured so that they can be removed in reverse order from the bathtub side. It is possible, and the pre-filter, nozzle, throttle, and air check valve are intensively mounted in the suction / discharge unit provided on the side wall in the bathtub. The air check valve can be attached and detached at a single location with high work efficiency, and therefore, the maintenance worker can sufficiently and reliably perform maintenance services for the customer, thereby increasing the maintenance effect. Things.
