Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a steam iron equipped with a removable tank for general household use.

Conventional configurations and their problems Generally speaking, steam irons with a removable tank require that the tank be removed from the iron body.
This makes filling and draining water easier by carrying just the tank.

Conventionally, this type of steam iron is classified based on the method of supplying water to the tank.As shown in Fig. 1, a nozzle 2 is installed at the bottom of a tank 1, and the iron can be opened and closed by operating an operation button 3 attached to the top. By moving the member 4 up and down, the water supply hole 5 of the nozzle 2 is opened and closed to supply water, that is, the water is dripped by its own weight, and as shown in FIG. A gasket 8 that slides inside the cylinder 7 is attached to the operation button 6 attached to the cylinder 7 to form a piston, and when the operation button 6 is raised, water in the tank 9 flows into the cylinder 7 through the suction channel 10. Then, when the operation button 6 is lowered, the check valve 11 made of a steel ball or the like closes the suction channel 10, and the cylinder 7
The water inside passes through the water supply channel 13 communicating with the water supply hole 12, pushes down the opening/closing member 14 made of a steel ball that had previously closed the water supply channel 13, and is released from the water supply hole 12, that is, by the pump device. It was common to have a structure that supplied water.

However, in the structure shown in Figure 1,
When the tank 1 is removed and water is poured or drained, or when the removed tank 1 is left unattended during ironing work, the water supply hole 5 must be closed to prevent water from flowing out of the tank 1. Was. Furthermore, in the structure shown in FIG. 2, even if the tank 9 is removed, the opening/closing member 14 closes the water supply channel 13 unless the operation button 6 is operated.
Although water does not flow out from the water supply hole 12, even if the water in the tank 9 is drained, water remains in the cylinder 7 and the water supply channel 13, and if you operate the operation button 6 without realizing it after draining, the cylinder 7 There was also a problem that the water in the water supply channel 13 was released and wet the surrounding area.

Purpose of the Invention The present invention solves these conventional problems and prevents the water in the tank from flowing out and wetting the surrounding area even if the operation button is operated by mistake when the tank is removed. To provide a steam iron with improved usability.

Structure of the Invention In order to achieve the above object, the steam iron of the present invention includes a base having a vaporization chamber, a tank having a water supply hole at the bottom and removably disposed above the base, and the water supply a connecting member that communicates between the hole and the vaporization chamber; and a connecting member provided in the tank, and
a first opening/closing member that opens and closes a water passage that communicates with the water supply hole and is provided on the upstream side of the water supply hole using an operating section; a second opening/closing member that opens and closes;
The opening/closing member is provided with a spring that urges each of the opening/closing members in the closing direction.

DESCRIPTION OF EMBODIMENTS Hereinafter, as an embodiment of the present invention, an embodiment applied to a pump device for an iron will be described with reference to the accompanying drawings.

In FIGS. 3 and 4, 20 is a heater 21
22 is a lid made of metal such as aluminum, which watertightly covers a vaporization chamber 23 formed in the base 20 and has a vaporization chamber hole 24. 25 is a tank, and 26 is a nozzle provided protruding from the bottom of the tank 25, and has a water supply hole 27. A connecting member 28 communicates the water supply hole 27 of the nozzle 26 with the vaporizing chamber 23, and is made of an elastic material such as silicone rubber.

Reference numeral 29 denotes a pump device, and its configuration will be explained in detail next. Reference numeral 30 denotes an operation button which is the operation part of the pump device 29 which is attached to the upper part of the tank 25 so as to be able to move up and down. 31 is an elastic member made of rubber or the like that slides on the inner surface of the cylinder 32. A push nut 33 is attached to the lower part of the operation button 30. It is installed by etc. 3
Reference numeral 4 denotes a suction channel extending downward from the cylinder 32, and its water suction port 35 is formed slightly away from the bottom surface of the tank 25. 36 is a water passage that communicates the cylinder 32 and the water supply hole 27. 37 is a check valve made of a steel ball or the like that opens and closes the suction channel 34; 38 is a first opening/closing member that is made of a steel ball or the like and opens and closes the water passage 36; 39 is a second opening/closing member that opens and closes the water supply hole 27; The first and second opening/closing members 38 and 39 are biased by a spring 40 so as to close the water passage 36 and the water supply hole 27, respectively. Note that the second opening/closing member 3
The lower end 41 of the nozzle 9 passes through the water supply hole 27 and the nozzle 2
It protrudes downward from 6. The cost is tank 2
5 is configured in a dimensional relationship such that when it is attached to the iron main body 42, it hits the top surface of the lid 22 and is pushed up slightly. Furthermore, the outer diameter A of the lower end portion 41 of the second opening/closing member 39 is the inner diameter B of the water supply hole 27.
Origatsu is made smaller and has a gap for water to pass through,
When the tank 25 is removed, the upper outer diameter C of the second opening/closing member 39 is determined by the gap.
The diameter is designed so that the water supply hole 27 can be closed even if the diameter 9 is misaligned. Furthermore, the vaporization chamber hole 24 of the lid 22
is provided at a position shifted from a position corresponding to the lower end 41 so that the lower end 41 of the second opening/closing member 39 does not enter.

To explain the operation in the above configuration, tank 2
5 is attached to the iron main body 42, the lower end 41 of the second opening/closing member 39 hits the top surface of the lid 22 and is pushed upward to open the water supply hole 27. Therefore, by operating the operation button 30 up or down, the tank 25 The water inside can be supplied to the vaporization chamber 23 through the suction channel 34, the cylinder 32, the water passage 36, the water supply hole 26, and the vaporization chamber hole 24 in this order.

Furthermore, when the tank 24 is removed, the second opening/closing member 39 is biased by the spring 40 and closes the water supply hole 27. Even if the operation button 30 is operated while water remains in the water passage 36, the water will not flow out from the water supply hole 27. That is, even if the operation button 30 is operated by mistake with the tank 25 removed, the surrounding area will not get wet.

In the above embodiment, the water in the tank 25 is supplied to the vaporization chamber 24 by the pump device 29. However, as another embodiment, as shown in FIG. By moving the first opening/closing member 51 up and down by the operation 50, the water passage 52 is opened and closed to supply water. That is, even if the structure is such that water drips due to its own weight, the second opening/closing member 55 that opens and closes the water supply hole 54 may be attached by attaching and detaching the tank 53. Further, although this embodiment uses a manual pump device 29, an electric one may be used.

Effects of the Invention As described above, the steam iron of the present invention includes a base having a vaporization chamber, a tank having a water supply hole at the bottom and removably arranged above the base, and the water supply hole and the vaporization chamber. a first opening/closing member that is provided in the tank and that opens and closes a water passage that communicates with the water supply hole and is provided on the upstream side of the water passage by means of an operating section; and a second opening and closing member that opens and closes the water supply hole in response to attachment and detachment of the tank, and a spring that biases both opening and closing members in the closing direction, so that the tank can be removed from the iron body. This prevents the water in the tank from accidentally leaking out even if an operator accidentally operates the operation part while the tank is in the iron body. Since the water inside can be directly supplied to the vaporization chamber, steam can be quickly ejected in response to frequent switching operations between dry and steam during ironing operations.
