Abstract

(57) [Abstract] [Purpose] It is an object of the present invention to provide a tank structure in which the inner tank can be easily arranged inside the outer tank and the tank can have a double structure. [Constitution] The inner tank 7 arranged inside the outer tank 6 is formed into a contractable bellows shape.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a toilet tank structure capable of storing flush water.

[0002]

[Prior art and its problems]

 Conventionally, in toilet bowls for cold regions, etc., the tank for storing wash water has a double structure to prevent freezing of the wash water and to prevent dew drops from forming on the outer circumference of the tank. If the outer tank has a small opening and a large depth, it is impossible to store the inner tank inside the outer tank. There was a problem that it was difficult.

[0003]

[Means for Solving the Problems]

 The present invention has been devised in view of the above-mentioned conventional problems, and even if the opening of the outer tank is small, the inner tank can be favorably accommodated inside and a double structure is provided. The purpose of the present invention is to provide a container for a toilet having a double structure in which the inner tank is arranged inside the outer tank, and the inner tank is formed into a contractable bellows shape.

[0004]

[Action]

 Since the inner tank is formed in a bellows shape and can be contracted, even if the opening of the outer tank is small and the depth is large, the inner tank is stored in the outer tank in a contracted state, and the inner tank is stretched after storage. A good double structure can be obtained.

[0005]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional configuration diagram of a one-piece toilet bowl, in which a bowl portion 2 is formed in the toilet body 1, a rim portion 3 is formed on the outer periphery of the bowl portion 2, and the bowl portion 2 communicates with the bowl portion 2. The trap portion 4 is formed in a circular shape, the drain pipe portion 5 is connected to the downstream side of the trap portion 4, the outer tank portion 6 is integrally formed at the rear portion of the toilet body 1, and the outer tank portion 6 is formed. A tank space S is formed inside.

The outer tank portion 6 is formed such that the opening area of the upper surface opening 6 a on the upper surface side is small and the depth of the tank space S is large. An inner tank 7 is disposed in the tank space S, and the inner tank 7 is made of resin and formed in a bellows shape. The inner tank 7 can be expanded and contracted in the vertical direction through the bellows, and is in the contracted state. The silicon caulking 8 is placed between the outer periphery of the upper end of the inner tank 7 and the inner periphery of the outer tank part 6 in a state of being put in the tank space S through the upper surface opening 6a of the outer tank part 6 and extended vertically in the tank space S. And a gap is formed between the inner circumference of the outer tank portion 6 and the outer circumference of the inner tank 7 to form a double structure.

The lower end of the inner tank 7 is attached to a valve seat fitting 9 fixed in advance on the toilet body 1, and an overflow pipe 10 is connected to the valve seat fitting 9. A ball valve 11 and a float 12 can be arranged in the inside of the unit 7 to complete the mounting.

As described above, in this example, since the inner tank 7 is formed into a resin bellows shape and is expandable and contractible, even if the outer tank portion 6 has a small opening 6a and a large depth, The inner tank 7 can be disposed in the tank space S of the outer tank portion 6 satisfactorily later. As a matter of course, in the case where the upper surface opening 6a of the outer tank portion 6 is formed in a wide shape, the inner tank 7 can be easily disposed, and the inner tank 7 of any shape can be satisfactorily lately generated. Can be arranged, and versatility is expanded.

In such a double structure toilet bowl, if the washing water is stored in the inner tank 7, the outer tank portion 6 exists through the gap, so that the washing water in the inner tank 7 is washed. It is possible to satisfactorily prevent the freezing of the inner tank 7 and the heat of the inner tank 7 is not transmitted to the outer tank portion 6, so that dew droplets do not occur on the outer periphery of the outer tank 6 and the toilet bowl has a good dew-proof structure. can do.

[0010]

[Effect of device]

 The present invention is a tank of a toilet having a double structure in which the inner tank is arranged inside the outer tank, and by forming the inner tank into a bellows shape that can be contracted, the outer tank portion has a small opening and a depth. Even if it has a large shape, it is possible to store the inner tank in the outer tank part in a contracted state well afterwards, and it can be stretched after the storage, and it can be easily placed inside the outer tank part of any shape. Has the effect of being able to form a double-structure tank.
