Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a water storage tank device for a pump-type spray and a steam iron with an increasing steam function for general household use.

Structure of the conventional example and its problems Conventionally, the water storage tank of this type of steam iron has a pump cylinder 2, a water inlet 3, a spray outlet 4, and a A pump device is constructed of a piston unit 5, a check valve 6, a spray tube 7, a spray nozzle unit 8 at the front of the tank 1, and a cover 9 covering these.
It was to be ejected from a piste. On the other hand, irons include those that have the above-mentioned spray function, those that have the function of sending the sucked up water to the steam generation chamber to obtain increased steam, those that have both of these functions, and those that require a pump device. It is becoming more and more diverse.

Against this background, manufacturers either manufacture water storage tanks according to the function each time, or they manufacture a part of the pump cylinder integrally with the water storage tank, and for models that do not require a part of the pump cylinder, they create a water storage tank depending on the function. It was shared by filling it with another lid material 10. However, with this method, even in steam irons that do not require a pump device, a portion of the cylinder is formed, resulting in material loss. In this case, a part of the internal cylinder can be seen through, which causes problems such as an unsightly appearance.

OBJECTS OF THE INVENTION The present invention solves these conventional problems and provides a water storage tank with a rational configuration that is compatible with a wide variety of models.

Structure of the Invention The water storage tank of the present invention has an opening hole formed in the upper part of the tank constituting the water storage tank, and a lid body integrated with a pump device shaped according to the function is attached to the opening hole.
It can be used with all diversified steam irons simply by replacing the lid.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

4 to 8, 11 is a base of an iron having a vaporization chamber 12, 13 is a handle attached to the base 11, and 1
4 is a tank in front of the handle 13, and 15 is a water supply device attached to the top of the tank to supply water to the vaporization chamber 12. Reference numeral 16 indicates an opening hole formed on the top surface of the tank 14, and reference numeral 17 indicates a pump 7 used for an iron having a spray function, in which a water intake port 18 and a discharge port 19 are integrally formed.
A flange-like lid body 20 is formed to close the opening hole 16 of. 21 is a water pipe connected to the discharge port 19, 22 is a spray nozzle provided at the tip of the water pipe 21, 23 is a valve for preventing backflow disposed inside the pump cylinder 17, and 24 is a piston unit having an operating part 25. pump cylinder 17
It is provided so that it can slide freely inside. 26 is a pumping pipe that is attached to the water intake port 18 and extends to the bottom of the tank 14;
A water supply port provided on the front surface of the water supply port is closed by a water supply lid 27.

In FIG. 8(b), reference numeral 28 denotes a pump cylinder used in an iron having a steam increasing function, around which a flange-shaped lid 29 is formed to close the opening hole 16 of the tank 14.

In FIG. 8(C), reference numeral 30 denotes a pump cylinder used in an iron having both a spray function and an increasing steam function, and a flange-shaped lid 31 is formed around the periphery to close the opening hole 16 of the tank 14.

These pump cylinders 17.28, '30 lid body 2
0, 29.31 are formed in the same shape and have the same vertical dimension L1. Both have a horizontal dimension L2, and can close the opening hole 16 of the tank 14. Therefore, if the lid 20 is attached to the opening hole 16, an iron tank with a spray function can be installed, if the lid 29 is installed, an iron tank with an increased steam function can be installed, and if the lid 31 is installed, an iron tank with a spray function and the like can be installed. It is possible to assemble an iron tank with an increased steam function, and the outer shell of one tank can be shared by many types of irons.

In this way, the outer shell of one tank can be shared by many different types of irons, so only one mold is required. However, since the pump cylinder part is molded in a separate mold from the outside of the tank, the shape is not complicated and it is easy to mold.

Furthermore, during assembly, as shown in FIGS. 7 and 8(a), the water pipe 21, spray nozzle 22 and water pump 25
In the above embodiment, the opening hole 16 is formed on the top surface of the tank, but the opening hole may be formed on the side surface of the tank 14. Any structure may be used as long as it has a hole and a lid body equipped with a pump device according to the function, such as a part of a pump cylinder, is attached to this opening hole.

Effects of the Invention As is clear from the above-mentioned embodiments, the water storage tank device of the present invention is particularly designed by providing an opening hole on the outside of the basic water storage tank or in the V section, and blocking the opening hole of the lever of the lid body, which is a separate part. Because it is a product, there may be manufacturing compatibility,
Moreover, it is possible to improve the design quality.
