Abstract

PURPOSE:To improve filtering efficiency in a bathtub with a filter device wherein bathtub water is sent to the filter by means of a pump to perform filtering process. CONSTITUTION:Water of a bathtub 10 is circulated by a pump 16 through a pipe. Part of the water delivered from the pump 16 is filtered and processed through pipes 24, 28, a filter 30, and pipes 32, 42 and then introduced directly into the bathtub 10. Consequently, during a filtering operation, the filtered water leaving the filter 30 is returned directly to the bathtub 10, resulting in improved filtering efficiency.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub with a filter device, and more particularly to a bathtub with a filter device in which the filtration efficiency during filtration operation is enhanced.

[0002]

2. Description of the Related Art A tub with a filtering device, which circulates the water in the body of the tub by a pump and guides a part of the water discharged from the pump to a filtering device for filtering, is actually fair.
It is publicly known, for example, in Japanese Patent Publication No. 10893.

The structure of a bath with a filtering device of this type will be described with reference to FIGS. 3 and 4. A suction port 12 provided on a side wall of the bathtub 10 is provided with a pump 16 via a pipe 14.
Is connected to the suction port of. The discharge port of the pump 16 is connected to the jet port 20 of the bathtub 10 via a pipe 18.
This ejection port 20 is composed of a bubble ejection nozzle,
A pipe 22 for sucking air is connected.

A pipe 24 is branched from the middle of the pipe 18, and the pipe 24 is connected to a filtered water inlet of a filter 30 via a three-way valve 26 and a pipe 28. Filter 3
The filtered water discharge port of 0 is a pipe 32, a three-way valve 34 and a pipe 36.
It is connected in the middle of the pipe 14 via. In addition,
The middle of the pipe 24 and the three-way valve 34 are connected by a pipe 38. A pipe 40 for discharging backwash water is connected to the three-way valve 26.

In the bath with a filtering device constructed as described above, when the flow paths of the three-way valves 26 and 34 are set as shown in FIG. 3 and the pump 16 is operated, the water in the bath 10 is replaced by the pipe 14 and the pump. 16, the pipe 18 and the spout 20 in this order, together with the bubbles sucked from the pipe 22, the bath 1
It is jetted out to zero. Further, a part of the water discharged from the pump 16 is circulated through the pipes 24 and 28, the filter 30, and the pipes 32 and 36 in this order, and the filtering process is performed.

The filter 30 has a cylindrical filter material 30a made of porous ceramics and a bead-shaped filter material 30b disposed therein, and the water to be filtered contains a deposited layer of the beads 30b. After passing through, it passes through a filter material 30a made of porous ceramics and is filtered.

When dirt is accumulated on the filter media 30a, 30b, backwashing is performed by switching the flow path selection of the three-way valves 26, 34 as shown in FIG. That is, the three-way valve 26 connects the pipes 28 and 40, and the three-way valve 34 connects the pipes 38 and 32. When the pump 16 is operated in this state, a part of the water discharged from the pump 16 is discharged from the pipes 24 and 3.
8, 32, the filter 30, and the pipes 28, 40 are passed in this order, and the filter media 30a, 30b in the filter 30 are backwashed.

[0008]

In the bath with a filtering device shown in FIGS. 3 and 4, the water filtered through the filter 30 is introduced into the pipe 14 during the filtering operation. Therefore, part of the water that has been filtered and cleaned is diverted to the pipe 24 when discharged from the pump 16, and is sent to the filter 30 again without returning to the bathtub 10, resulting in poor filtration efficiency. There was a problem.

[0009]

A bath with a filtering device of the present invention comprises a bath body, a circulation system passage with a pump for extracting water from the bath body and returning it to the bath body, and the circulator. In a bath with a filtering device, which has a filtration channel separately provided so that a part of the discharge water of the pump is passed through, and a filter provided in the filtration channel, the filtered water of the filter is It is characterized in that the filtered water outlet of the filter and the bath body are directly connected by the filtration flow path so as to directly return the water to the bath body.

[0010]

In the bathtub with the filtering device of the present invention,
Since the water filtered by the filter is returned to the bath through a dedicated pipe, the filtration efficiency is extremely high.

Embodiments Embodiments will be described below with reference to the drawings. FIG. 1 is a flow path system diagram during a filtration operation of a bath with a filtration device according to an embodiment of the present invention, and FIG. 2 is a flow path system diagram during a backwash operation in this embodiment device.

In this embodiment, the three-way valve 34 and the bath 1
A pipe 42 and a jet port 44 exclusively for returning the filtered water are provided so as to directly connect to the filtered water jet port 44 of No. 0. That is, this embodiment is a modification of the conventional device shown in FIGS. 3 and 4, in which the pipe 36 is connected to the pipe 14,
The pipe 42 and the jet port 44 are installed so that the filtered water from the three-way valve 34 is directly returned to the bathtub 10. Other configurations are the same as those of the conventional device, and the same parts are denoted by the same reference numerals and the description thereof is omitted.

In the apparatus of this embodiment, when the filtration operation is performed, the flow path shown in FIG. 1 is selected. Then, with the operation of the pump 16, the water in the bathtub 10 flows in the order of the suction port 12, the pipe 14, and the pump 16. Some of the pump discharge water is pipes 18, 24, three-way valve 26, pipe 2
8, the filter 30, the pipe 32, the three-way valve 34, and the pipe 40 flow in this order and are filtered. The water filtered by the filter 30 is directly returned to the bath 10. Therefore, the filtered water is not sucked into the pump 16 again, and the entire amount of the filtered water is reliably returned to the bath 10. Therefore, the filtration efficiency is extremely good.

During the filtration operation, the pipe 22
By opening a valve (not shown) provided on the
Bubbling can be performed with water from 0. If this valve is closed, it is possible to perform the filtration operation without bubble ejection.

In the present invention, the filtered water ejection port 44 provided in the bath 10 may be constituted by a bubble ejection nozzle. With this configuration, when the filtered water is jetted into the bathtub 10, it is possible to also jet bubbles.

In the apparatus of this embodiment, in order to backwash the filter 30, the flow path selection shown in FIG.
6 is activated. Then, similarly to the case of FIG. 4, a part of the discharge water of the pump 16 is circulated in the reverse direction to the filter 30, and the filter media 30a and 30b are backwashed.

In the above embodiment, the pipe 42 is connected to the bath 1
Although it is connected to the filtered water jet port 44 of No. 0 in the present invention, as shown in FIG. 5, the pipe 4 is connected to the spout 46 provided on the bath wall 10 or the bathroom wall surface (not shown) in the vicinity thereof.
2 may be connected. If a waterfall spout is used as the spout 46, the filtered water flows down from the spout like a waterfall, and a unique atmosphere can be created.

[0018]

As described above, in the bath with a filtering device of the present invention, since the filtered water obtained from the filter is directly returned to the bath during the filtering operation, the filtration efficiency is extremely high. That is, the water in the bathtub can be made extremely sufficiently clean in a short time.
