Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filtering device connected to a bath such as a bath or a pool.

[0002]

2. Description of the Related Art In recent years, various improvements have been made to a filtration device connected to a bathtub or the like. Among them, for example, JP-A-2-59
The apparatus disclosed in Japanese Patent Publication No. 007 is shown in a block diagram of FIG. In this figure, a bathtub 4 having an inlet 41 and an outlet 42
The water 44 is stored in 3. Inlet 41 and outlet 42
A circulation path 45 is provided so as to communicate with
6, a heater 47, a circulation valve 48, a purifying unit 50 containing a purifying agent 49, and a circulation valve 51 are provided. A bypass 52 and a backwash valve 53 are provided in the middle of the circulation path 45, and a drainage path 54 and a drainage valve 55 are provided in the purification section 50.

[0003]

However, in the above-mentioned device, during normal use, the backwash valve 53 and the drain valve 55 are closed and the circulation valves 48 and 51 are opened to open the pump 46 and the heater 4.
By energizing 7, the hot water 44 is circulated in the direction of the solid line of the circulation path 45, and the hot water 44 is filtered by the purifying agent 49. When the hot water 44 is used for a certain period of time, a large amount of dirt is accumulated in the cleaning agent 49. Therefore, by closing the circulation valves 48 and 51 and opening the backwash valve 53 and the drain valve 55, the hot water 4
4 in the direction of the broken line of the circulation path 45 for drainage,
Is cleaning.

In order to clean the purifying agent 49 in this manner, the flow of the hot water 44 passing through the purifying agent 49 is simply made to flow in the opposite direction to that in normal use. Therefore, the dirt of the hot water 44 absorbed by the purifying agent 49 is removed. The first drawback is that the amount is small. Further, a total of four valves are required to change the flow of the hot water 44, and there is a second drawback that the cost of the apparatus becomes high. Therefore, in view of the above-mentioned conventional drawbacks, the present invention provides a filtration device which can remove a large amount of dirt accumulated in a cleaning agent and is inexpensive.

[0005]

In order to solve the above-mentioned problems, the present invention provides a tank having an inlet and an outlet, a circulation path communicating with the inlet and the exit of the tank, and a pump provided in the circulation path. And a purifying section which is composed of a rotatable container containing a granular purifying agent and which is arranged in the circulation path. Then, in order to clean the purifying unit, the water passing through the purifying unit is brought into contact with the purifying agent moving in the rotating container, and a discharge valve is provided so as to communicate with the purifying unit so as to discharge the water.

[0006]

As described above, according to the present invention, the cleaning agent contained in the cleaning section is brought into contact with each other by rotating the container constituting the cleaning section to move the cleaning agent contained therein. Since it falls into the inside, a large amount of dirt is removed.

One of the outlets is connected to the circulation valve 28, which is, for example, an electromagnetic valve, via the circulation path 4, and the circulation valve 28 is connected to the inlet 2 of the tank 1 via the circulation path 4. The discharge valve 29 is, for example, an electromagnetic valve, and is connected to the other outlet of the joint 27 via a discharge passage 30 formed of a silicone rubber hose or the like.
The outlet of the discharge valve 29 is connected to the discharge passage 31. The above-described components constitute the filtering device 32 of this embodiment.

Next, the operation of the present filtration device 32 during normal use will be described with reference to FIGS. In these figures,
First, the voltage applied to the discharge valve 29 is turned off and the valve is closed.
The voltage applied to the circulation valve 28 is turned on to open the valve. Water 33 is supplied to the tank 1, and the pump 5 and the heater 6 are turned on. As shown by the solid line direction in FIG. 1, the water 33 stored in the tank 1 passes through the outlet 3, is sucked in at the inlet of the pump 5, is pumped at the outlet, is heated by the heater 6 to become hot water 34, and is purified. When passing through the section 7, the dirt in the hot water 34 is purified in the purification section 7, passes through the circulation valve 28 via the joint 27, passes through the circulation path 4, passes through the inlet 2, and returns to the tank 1 again. Further, the same operation is repeatedly circulated through the outlet 3. At this time, the purification unit 7 is not rotating.

In this way, the hot water 34 is passed through the purifying section 7,
By filtering, the hot and cold water 34 is cleaned to keep the hot and cold water 33 in the tank 1 clean. However, if it is used for a long period of time, dirt of the purifying agent 9 accumulates in the purifying section 7 and the purifying ability deteriorates. Therefore, it is necessary to clean the cleaning unit 7 once every 2 to 6 months. Next, the operation during cleaning will be described again with reference to FIGS. 1 and 2.

In these figures, first, the circulation valve 28 is closed and the discharge valve 29 is opened. Turn on pump 5 and heater 6
Is turned off, the motor 22 of the purification unit 7 is turned on, and the purification unit 7 is rotated. As shown by the broken line direction in FIG. 1, the hot water 33 stored in the tank 1 passes through the outlet 3, is pumped by the pump 5, passes through the heater 6, passes through the purification unit 7, and passes through the purification unit 7. It is discharged to the outside of the device through the joint 27, the discharge passage 30, the discharge valve 29, and the discharge passage 31.

The state in which the cleaning unit 7 is cleaned will be described with reference to FIGS. 2 and 3. 3A is a cross-sectional view of the purifying unit 7, showing a state before rotation, and FIG. 3B shows a state during rotation. In these figures, the container 8 is rotating at a rate of once every few seconds. The plurality of purifying agents 9 are housed in the space surrounded by the inner side surface of the large tubular portion 10 and the partition plates 13 and 14 so that there is a slight gap in the upper portion. Therefore, when the container 8 rotates, the cleaning agent 9 therein easily moves easily, and the cleaning agents 9 come into contact with each other and rub against each other, so that the amount of dirt adhering to the cleaning agent 9 increases. Further, although the cleaning agent 9 has a spherical shape in the above description, the present invention is not limited to this and may have a cylindrical shape, a rectangular parallelepiped shape, or any other shape. Further, other known materials may be used as the material of the cleaning agent 9. Further, in the above description, the bath is exemplified as the bath 1, but the present invention can be applied to a bath such as a pool.

[0020]

As described above, according to the present invention, since the cleaning agent contained in the cleaning section is rotated to move the cleaning agent contained therein, the cleaning agents come into contact with each other and rub against each other. A large amount of dirt is removed because existing dirt falls into the discharged water.

Further, the conventional backwashing apparatus requires four valves, but the apparatus of the present invention requires only two valves, so the cost is low.
