  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
1 is a side sectional view of a main part of a steam iron according to Embodiment 1 of the present invention, FIG. 2 is a plan view of a water tank mounted on the steam iron, and FIG. 3 is a front end of an iron body of the steam iron. FIG. 4 is a cross-sectional view of a main part when the front end of the iron body is lowered.

  1 to 4, reference numeral 1 denotes an iron body, which includes a base 3 which is heated by a heater (not shown) and forms a vaporizing chamber 2. A water tank 4 for supplying water to the vaporizing chamber 2 includes a base 3. It is arranged above. The water tank 4 is provided with a pump device 7 having an operation unit 8 operated by an operator at the upper part. The pump device 7 includes a cylinder 5 and a piston 6 that is connected to the operation unit 8 and slides in the cylinder 5. The operation unit 8 is biased upward by a spring 8a. The discharge port 9 of the pump device 7 is connected to the vaporization chamber 2 via a water guide 10 and a connection 11.

  Further, the water inlet 12 for sucking water in the water tank 4 of the pump device 7 is a front end water inlet located at the front end in the longitudinal direction of the iron body 1 in the water tank 4 via the branch part 13 and the tubular communication pipe 14. 12a and the rear end water inlet 12b located at the rear end in the longitudinal direction of the iron body 1 in the water tank 4.

  A valve body 15 is disposed at each of the front end and rear end water inlets 12a and 12b. The valve body 15 includes a valve body main body 17 in which the water channel 16 is formed in a mortar shape as it approaches the pump device 7, a sphere 18 that closes each of the front end and rear end water inlets 12 a and 12 b, and the sphere 18 as a valve body. In order to hold in the main body 17, it is comprised with the cover body 19 which covers the open part of the valve body main body 17. As shown in FIG. The communication pipe 14 and the valve body 17 are integrally formed.

  The operation of the steam iron in the above configuration will be described below.

  When the operator operates the operation unit 8 and the piston 6 moves upward, the cylinder 5 is filled with water. At this time, when the front end of the iron body 1 is raised and used, the water in the water tank 4 concentrates behind the water tank 4 and there is no water near the front end water inlet 12a. Since 12a is blocked by the dead weight of the sphere 18, water can be absorbed from the rear end water inlet 12b opened by the own weight of the sphere 18 without sucking air from the front end water inlet 12a.

  Next, when the iron body 1 is used with the front end lowered, the water in the water tank 4 concentrates in front of the water tank 4 and there is no water near the rear end water inlet 12b. Since the water inlet 12b is closed by the weight of the sphere 18, the water can be absorbed from the front end water inlet 12a opened by the weight of the sphere 18 without sucking air from the rear end water inlet 12b.

  If the communication pipe 14 and the valve body main body 17 are formed integrally, air can be prevented from being sucked from the joint portion, so that water can be stably absorbed.

  Subsequently, when the operator operates the operation unit 8 to push down the piston 6, the water filled in the cylinder 5 is pushed out from the discharge port 9 of the pump device 7 and passes through the water guide unit 10 and the connection unit 11. Then, it is dripped into the vaporizing chamber 2 and a large amount of steam is generated.
