Description

The present invention relates to a tank device, and more particularly to a tank device for storing wash water to be supplied to a toilet bowl.

Conventionally, as a tank device for storing wash water to be supplied to the toilet bowl body, a pottery tank body forming an outer shell and a resin resin fixed inside the tank body and storing wash water inside. A tank device having a tank is known (for example, Patent Document 1). By forming the tank body with pottery in this way, the design can be improved.

In the tank device as described above, the size of the pottery tank body tends to vary due to manufacturing errors, so the resin tank must be designed so that there is a gap between it and the tank body. there were.

Japanese Unexamined Patent Publication No. 2003-27554

However, if a gap is provided between the tank body and the resin tank, the tank body will be impacted when the tank device is assembled or when the resin tank is transported in the assembled state inside the tank body. The resin tank may vibrate greatly inside.

As a result, stress is applied to the fixed portion of the resin tank, which may cause the resin tank to be unfixed or the fixed portion to be damaged.

The present invention has been made to solve the above-mentioned problems, and the resin tank vibrates greatly in the tank body when an impact is applied to the tank device while making the resin tank correspond to the dimensional variation of the tank body. It is an object of the present invention to provide a tank device capable of suppressing the operation.

The tank device according to one aspect of the present invention is a tank device that cleans the toilet bowl by supplying the washing water stored inside to the toilet bowl main body, and is attached to the inside of the tank main body forming the outer shell and the inside of the tank main body. The resin tank is provided with a resin tank for storing washing water, and the resin tank is provided on a side surface portion having a gap between the tank body and the side surface portion and a part of the side surface portion. It has a protruding portion protruding from a part of the tank toward the main body of the tank.

According to this configuration, since the gap between the resin tank and the tank body can be reduced, it is possible to suppress the resin tank from vibrating significantly in the tank body even when an impact is applied to the tank device. .. In addition, since the protrusion is provided on a part of the entire circumference of the resin tank instead of the entire circumference, even if the dimensional variation occurs in the tank body due to manufacturing errors, the region where the protrusion of the resin tank is not provided is deformed. By doing so, it is possible to absorb variations in dimensions. As a result, the resin tank can be made to cope with the dimensional variation of the tank body.

In the tank device according to one aspect of the present invention, the protrusion is preferably provided at a corner of the resin tank.

According to this configuration, it is possible to prevent the resin tank from vibrating significantly in the tank body even when an impact is applied to the tank device, while making the resin tank correspond to the dimensional variation of the tank body.

In the tank device according to one aspect of the present invention, preferably, the protrusion width of the protrusion can be adjusted from the side surface portion toward the tank body side.

According to this configuration, the protruding width of the protruding portion can be adjusted according to the situation, so that the resin tank can be mounted in the tank main body of various sizes.

In the tank device according to one aspect of the present invention, the protruding portion is preferably a separate body from the resin tank and can be attached to and detached from the resin tank.

According to this configuration, since the protruding portion can be selected according to the size of the tank body, the resin tank can be mounted in the tank body of various sizes.

According to the tank device of the present invention, it is possible to prevent the resin tank from vibrating significantly in the tank body when an impact is applied to the tank device while making the resin tank correspond to the dimensional variation of the tank body.
