DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water tank with a drain port.

[0002]

2. Description of the Related Art Conventionally, there has been proposed a water tank having a drain port provided with a drain port on the bottom of the tank so that the water in the tank can be easily replaced. The water tank with a mouth has a drawback that gravel or the like spread on the bottom of the water tank is discharged together with drainage of water.

[0003] The present invention focuses on such a drawback, and it is possible to satisfactorily drain only water from the inside of a water tank, and to stably mount the same as a normal water tank while forming a bottom surface on an inclined surface.
An object of the present invention is to provide an excellent water tank with a drain port, in which a portion vertically provided at the bottom of the water tank is not exposed in appearance.

[0004]

The gist of the present invention will be described with reference to the accompanying drawings.

A bottom surface of the water tank 1 is formed in an inclined manner, and a drain port 2 is provided at a lower position of the bottom of the water tank 1, and a drain introduction portion 3 is provided below the drain port 2 at a bottom of the water tank 1. 2
Alternatively, a perforated plate 4 for preventing gravel or the like spread in the water tank 1 from being drained in the drainage introduction unit 3 or a filter 5 for adhering dust or the like is provided. A lower receiving case 7 for supporting the water tank 1 is disposed at the bottom of the lower case 1 so as to cover the lower water introducing portion 3 which is vertically suspended, and the drain valve 6 is provided on a side portion of the lower receiving case 7. The present invention relates to a water tank with a drain port provided with a discharge window 8 to be protruded.

[0006]

When the drain valve 6 is opened, almost all of the water in the water tank 1 is introduced from the drain port 2 to the drain introduction section 3 along the inclined surface at the bottom, and flows out from the drain valve 6. A hose is connected to the drain valve 6 through a discharge window 8 or the drain valve 6 is disposed so as to protrude from the discharge window 8 to drain water.
At this time, since a drain plate 2 or a filter 5 for adhering dust or the like is provided in the drain port 2 or the drain introduction portion 3 to prevent the gravel or the like spread in the water tank 1 from draining, so that the gravel or the like is provided together with the water. Is not discharged, and the drained water is discharged after being filtered.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In a water tank 1 of this embodiment, a drain port 2 is formed at an eccentric position on the bottom, and the bottom of the water tank 1 is inclined so that the drain port 2 is at the lowest position. It is configured such that water can be satisfactorily led out to the drain port 2 along the inclined bottom surface.

A drainage introduction section 3 for storing water introduced from the drainage port 2 is vertically formed integrally with a bottom of the water tank 1 below the drainage port 2, and a drainage introduction section is formed on a lower side surface of the drainage introduction section 3. A drain valve 6 for draining the stored water in 3 is provided. The drain valve 6 is provided with an opening / closing lever 6 ′ at the upper portion, and the opening and closing of the drain valve 6 can be controlled by twisting the opening / closing lever 6 ′.

In the present embodiment, a drainboard as a filter 5 for adhering dust and the like contained in water is detachably provided in the drainage introduction section 3. The filter 5 is provided with installation legs 11 on the bottom left and right so as to be installed and held at a position higher than the drain valve 6.
The water introduced into the filter is filtered through the filter 5 and then discharged from the drain valve 6.

Further, the drainage introduction section 3 provided with the filter 5 is closed from above, and gravel or the like spread on the bottom of the inner portion of the water tank 1 at the opening edge of the drainage port 2 drains from the drainage port 2 together with water. A perforated plate 4 for preventing this is detachably provided.

A drainage introduction section 3 is provided at the bottom of the water tank 1.
Further, the water tank 1 is supported so as to cover the drain valve 6, and a box-shaped lower receiving case 7 capable of stably mounting the water tank 1 on the grounding surface is provided. The lower receiving case 7 is configured such that a drain window 8 is provided at a side position where the drain valve 6 provided therein faces the drain window 6 so that the drain valve 6 faces the drain window 8. By connecting a hose to the drain valve 6, drainage can be performed. Further, a cover 9 for closing the discharge window 8 is provided in the lower receiving case 7 so that the drain valve 6 cannot be seen from the discharge window 8 except during drainage.

In the present embodiment, the hose is connected to the drain valve 6 provided on the discharge window 8 through the discharge window 8 to drain water. However, the drain valve 6 is disposed so as to protrude from the discharge window 8. The drainage valve 6 may be configured to be able to directly drain water.

Reference numeral 10 in the figure denotes a lid for closing the upper opening of the water tank 1.

[0014]

The present invention is constructed as described above. If the hose is connected to the drain valve through the discharge window, or if the drain valve is protruded from the discharge window, the water in the water tank can be easily reduced. Can be drained, and a drain hole or a drainage inlet is provided with a perforated plate that prevents the gravel and the like laid in the water tank from draining, or a filter that allows garbage to adhere. It is a water tank with a drain port that exhibits extremely excellent practical effects, such that gravel and the like are not discharged, and the drained water is filtered and then discharged.

Further, since a lower receiving case for supporting the water tank is provided so as to cover the drainage introduction part vertically hanging down from the bottom of the water tank, the bottom surface of the water tank is formed as an inclined surface. It has an excellent effect that it can be stably placed like a water tank and the drainage introduction part and the drainage valve, which are installed at the bottom of the water tank, are not exposed in appearance.
