Abstract

PURPOSE: To drain only water from a water tank in good performance, form the tank in the same fashion as a usual one which can be placed stably despite its inclined bottom surface, and hindering the part dangling at the tank bottom from being exposed in terms of outside sppearance. CONSTITUTION: The bottom surface of a water tank 1 is formed inclined, and a drain hole 2 is furnished at the lower position of the inclination of tank bottom, and a drain water introducing part 3 is provided in the lower part of the drain hole 2 in such a way as dangling at the tank bottom. The drain hole 2 or drain water introducing part 3 is fitted internally with a catch basin 4 for preventing gravel, etc., laid in the water tank 1 from being exhausted or a filter 5 to which rubbish, etc., is attached, and drainage valve 6 is installed in the part 3. At the bottom of the tank 1 a lower receiving case to bear it is installed in such a way as enclosing the drain water introducing part 3 dangling at the bottom. At the side of the case, a drainage window 8 is furnished for installation of the valve 6 in such a way as confronting or protruding.

Description

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 drainage port.

[0002]

2. Description of the Related Art Conventionally, there has been proposed a water tank with a drain port provided with a drain port on the bottom surface of the water tank so that water in the water tank can be easily replaced. The mouth water tank has a drawback that gravel and the like spread on the bottom of the water tank are also discharged when the water is drained.

The present invention pays attention to such drawbacks and can drain water only from the inside of the water tank satisfactorily. Further, the bottom surface of the water tank can be stably placed like an ordinary water tank even if it is formed.
It is intended to provide a water tank with an excellent drainage port, in which the portion vertically hung on 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.

The bottom surface of the water tank 1 is formed to be inclined, and a drainage port 2 is provided at a lower inclined position of the bottom surface of the water tank 1. A drainage introducing portion 3 is provided below the drainage port 2 so as to extend vertically from the bottom of the water tank 1. Two
Alternatively, the drainage inlet 3 is provided with a perforated plate 4 for preventing the gravel or the like spread in the water tank 1 from draining, or a filter 5 for adhering dust and the like, and a drainage valve 6 is provided in the drainage inlet 3. A lower case 7 for supporting the water tank 1 is arranged at the bottom of the lower cover 1 so as to cover the downwardly extending drainage introduction part 3, and the drain valve 6 is provided on the side of the lower case 7. The present invention relates to a water tank with a drainage port, which is provided with a discharge window 8 which is arranged to project.

[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 part 3 along the inclined surface of the bottom part and flows out from the drain valve 6. A hose is connected to the drain valve 6 through the drain window 8 or the drain valve 6 is disposed so as to project from the drain window 8 for draining.
At this time, since the drainage port 2 or the drainage introducing portion 3 is provided with a perforated plate 4 for preventing drainage of gravel or the like spread in the water tank 1 or a filter 5 for adhering dust or the like, gravel or the like together with water is provided. Will not be discharged, and the drained water will be discharged after being filtered cleanly.

[0007]

EXAMPLE A water tank 1 of this embodiment has a drain port 2 formed in an eccentric position on the bottom surface, and the bottom surface of the water tank 1 is inclined so that the drain port 2 is at the lowest position. It is configured so that water can be satisfactorily led to the drainage port 2 along the inclined bottom surface.

A drainage introducing portion 3 for storing water introduced from the drainage outlet 2 is vertically formed integrally with the bottom portion of the water tank 1 below the drainage outlet 2, and the drainage introducing portion is provided on a lower side surface of the drainage introducing portion 3. A drain valve 6 for draining the accumulated water in 3 is attached. The drain valve 6 is provided with an opening / closing lever 6'on its upper portion, and the opening / closing lever 6'is twisted to control the opening / closing of the drain valve 6.

In this embodiment, a sludge as a filter 5 for adhering dust and the like contained in water is detachably arranged in the drainage introducing portion 3. The filter 5 is provided with installation legs 11 on the left and right sides of the bottom so that the filter 5 can be installed and held at a position higher than the drain valve 6.
The water introduced therein is filtered by the filter 5 and then discharged from the drain valve 6.

[0010] Further, the drainage introducing portion 3 in which the filter 5 is arranged is closed from above, and the gravel or the like spread on the opening edge of the drainage outlet 2 is drained from the drainage outlet 2 together with the water. A perforated plate 4 for preventing this is detachably arranged.

At the bottom of the water tank 1, a drainage introducing part 3
In addition, the water tank 1 is supported so as to cover the drain valve 6, and the box-shaped lower case 7 that can stably mount the water tank 1 on the grounding surface is provided. The lower case 7 is configured such that a drainage window 8 is provided at a side position facing the drainage valve 6 provided therein so that the drainage valve 6 is placed in the drainage window 8 through the drainage window 8. The drainage valve 6 is connected to a hose so that the drainage can be performed. Further, the lower case 7 is provided with a lid 9 for closing the drainage window 8 so that the drainage valve 6 cannot be seen through the drainage window 8 except when draining.

In the present embodiment, the drain valve 6 provided on the discharge window 8 is connected to the hose via the discharge window 8 to drain water. However, the drain valve 6 is disposed so as to project from the discharge window 8. The drain valve 6 may be constructed so that the water can be drained directly.

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

[0014]

Since the present invention is constructed as described above, if the hose is connected to the drainage valve through the drainage window or the drainage valve is provided so as to project from the drainage window, the water in the water tank can be easily made. It is possible to drain water, and at the same time, a drainage port or a drainage introduction part is provided with a filter to prevent drainage of gravel, etc. spread in the water tank, or a filter to attach dust. The gravel will not be discharged, and the drained water will be discharged after being filtered out cleanly, and it will be a water tank with a drain outlet that exhibits extremely excellent practical effects.

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