BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter for a water tank for filtering rainwater supplied to a water tank for rainwater use, and more particularly to a method for preventing dust contained in rainwater from being discharged into the water tank. The present invention relates to a water tank filter that can easily remove dust.

[0002]

2. Description of the Related Art Conventionally, various water storage tanks have been devised for use of rainwater, and a general water storage tank in which a water storage tank is provided for a downspout has also been devised (Japanese Utility Model Laid-Open No. 54-122418). .

In addition, rainwater often contains dust such as dirt on a roof and sand and dust on the inner wall of an eaves gutter or a vertical gutter, and has a problem that it is supplied to the water storage tank together with the rainwater. Therefore, in the device disclosed in the publication, a cleaning hole is provided on the lower wall surface of the water storage tank to discharge the dust.

[0004]

However, it is difficult to completely clean the dust accumulated on the bottom using only the cleaning hole, and it is necessary to turn the water tank upside down in order to perform the fundamental cleaning. There was a problem that it took time and effort. Further, there is also a problem that dust accumulated on the bottom of the water storage tank decays rainwater in the water storage tank, and the dust acts as a medium to generate mold and bacteria in the water storage tank.

An object of the present invention is to solve the above-mentioned problem of the conventional product. In this case, while filtering rainwater, the dust contained in the rainwater is concentrated in one place and is stored in a water storage tank. An object of the present invention is to provide a filter for a water storage tank which can be collectively discarded without being discharged.

[0006]

That is, the present invention has been devised in view of the above, and has an opening formed in a wall surface of a water storage tank, and a water supply port, a drain port and a connection in which respective inner walls communicate with each other. The water supply port of the connector provided with the ports arranged in three different directions is inserted through the opening, while the drain port is disposed above the connection port, and the filter body is detachably attached to the drain port. A water reservoir filter, wherein a container is detachably disposed at the connection port, and further, a rainwater supply pipe in which a rain gutter communicates with an inner wall communicates with each inner wall of the water supply port. is there.

[0007] The connecting device in the present invention is for arranging a device for filtering dust contained in rainwater received by the water storage tank. In the filtering, the filtering device is provided with a filter body for receiving rainwater received at a water supply port from a rainwater supply pipe. It is performed when discharging from an outlet to a water storage tank, and is performed by accumulating dust in a container connected to the connection port. Here, the reason why the filter is arranged higher than the container is to drop dust contained in rainwater into the container. On the contrary, the dust is undesirably deposited on the filter and clogged. Therefore, various shapes such as a T-shape and a Y-shape can be adopted as the connecting tool if the positional relationship is maintained when the connecting tool is disposed in the water storage tank. In addition, it is preferable that there is no gap between the tubular member constituting the water supply port and the opening so that water in the water storage tank does not leak,
As means for this purpose, for example, there is a means for forming a shape in which the two are fitted, or a method for arranging a material such as rubber or caulking material in the gap to fill the gap.

[0008] The above-mentioned filter filters dust contained in rainwater, and its effect is reduced by long-term use. Therefore, the filter is detachably provided at the discharge port, thereby making it possible to replace the filter. Various conventionally known means can be adopted as the detachable means, such as screwing,
There is a mechanical or elastic fitting. In addition, it is a matter of course that a commercially available or general-purpose water faucet filter can be used as the filter.

The above-mentioned container has a bottom and accumulates dust that is not discharged into the water storage tank by the filter. Since the dust accumulates inside the container after a long-term use, the container is detachably provided to the connection port. This enables replacement. As the detachable means, various conventionally known means can be adopted, for example, screwing, fitting by mechanical or elastic force means and the like. In addition, the container can be used as a place for utilizing the waste by using a waste product of a commercially available container for storing a detergent. In such a case, the internal shape of the connection port is changed to the opening of the container for storing the detergent. By matching the shape of the container, the container can be removably provided to the connection port. The container member is preferably formed of a transparent member in order to confirm the amount of dust accumulated inside the container.

[0010]

According to the present invention, a filter and a connector provided with a container for accumulating dust at a position below the filter are provided in a rainwater storage tank, thereby filtering the rainwater, Do not concentrate the dust contained in the water in one place and discharge it into the water tank. Further, by disposing the container in a detachable manner, dust is collectively discarded by cleaning the inside of the container or replacing the container.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings. FIG. 1 is a cross-sectional view schematically showing a main part of an embodiment of a water tank filter according to the present invention.

As shown in FIG. 1, a filter for a water storage tank according to this embodiment includes a water storage tank 1 (not shown in its entirety) and a water supply port 4, which has a T-shaped vertical cross section and whose inner walls communicate with each other. A connector 3 having a drain port 5 and a connection port 6;
A filter body 7 detachably mounted on the container, a container 8 detachably mounted on the connection port 6, and a part of the connector 3 constituting the water supply port 4 are inserted into the opening 2 of the water storage tank 1. It comprises a rainwater supply pipe 9 which is inserted and connected so as to communicate with each other's inner walls.

The drain port 4 is opened upward in the figure and is fitted and connected into a rubber opening of the filter body 7. The connection port 6 is opened at the bottom of the figure and is screwed to a transparent commercially available container 8 for packing detergent. The internal structure of the connection port 6 of the connection tool 3 has a male-female relationship with the screw at the opening of the container 8, whereby the connection tool 3 and the container 8 are detachably screwed. The opening 2 of the water storage tank 1 and the connector 3 are fitted to such an extent that water does not leak from between them, and the rainwater supply pipe 9 is fitted to the connector 3 with its own elasticity. .

The filter of the water tank configured as described above exerts the effects of the present invention by the operation described below.

Rain water W supplied from a rain gutter (not shown)
Is supplied to the connection port 6 via the rainwater supply pipe 9, flows into the container 8 via the connection tool 3, passes through the filter body 7, and is discharged into the water storage tank 1. Here, the dust G such as sand and dust is accumulated in the container 8 because the dust is larger than the eyes of the filter body 7 and the weight of the dust itself, and further, since the container 8 is disposed below the filter body 7. Is done. In addition, even if the inside of the connection tool 3 is full, the filter main body 7 prevents the dust G from being discharged into the water storage tank.
Needless to say, the same effects as described above can be obtained.

In this embodiment, the connecting member is connected to a longitudinal section T.
Because it is shaped like a letter, the power of rainwater supplied is alleviated by the inner wall while dust such as sand and debris is not discharged into the water tank and the rainwater is filtered, while the dust contained in the rainwater is removed from the container. Has the effect that it can be concentrated in one place. Further, when the water level in the water storage tank falls, the container is taken out and cleaned or replaced, so that dust obtained by filtration can be collectively discarded, thereby eliminating the necessity of cleaning the water storage tank itself. Having.

FIG. 2 discloses another embodiment according to the present invention. In this embodiment, the connector of the above embodiment is formed in a Y-shape. In this embodiment, the filter body 7
And the container 8 are formed obliquely with respect to the wall surface of the water storage tank 1, so that there is an effect that replacement is easier than in the previous embodiment.

[0018]

According to the present invention, the filter of the water storage tank is provided with a water supply port, a water discharge port, and a connection port in which the respective inner walls communicate with each other. While the mouth is inserted into the opening formed in the wall surface of the water storage tank, the drain port is disposed above the connection port, a filter body is detachably disposed at the drain port, and a container is provided at the connection port. A rainwater supply pipe in which a rain gutter and an inner wall communicate with each other and an inner wall of each of the water supply ports are formed so as to communicate with each other so that dust contained in rainwater is discharged into the water storage tank. While filtering rainwater without doing so, there is an effect that cleaning of the water storage tank becomes unnecessary only by replacing or cleaning the container. Furthermore, since dust does not accumulate in the water storage tank, there is an effect that rainwater in the water storage tank does not decay and mold and bacteria are not generated.
