Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a steam iron equipped with a water supply device for use in general households.

Conventional Structure and Problems Conventionally, in a steam iron equipped with this type of water supply device, when the piston 1 is raised as shown in FIG. When the water flows into the cylinder 4 and then lowers the piston 1, the check valve 5 closes the suction channel 3, and the water in the cylinder 4 is transferred to the water supply pipe 7, which is the water supply channel 6. Steam was fed into the vaporizing chamber 9 through the gasket 8 and an increased amount of steam was generated from the steam hole 1o. The lower end of the water pipe 7 is attached to a water pipe support stand 12 which is provided integrally with the heat insulating plate 11 on the bottom of the tank portion 2, and the seal 8 is attached to a seal support stand 13 which is similarly provided integrally with the heat insulating plate 11. Attach the heat insulating board 11 and vaporization chamber cover 14
This compresses the packing 8 to prevent water leakage.

However, with the above-mentioned conventional configuration, the configuration for feeding the water in the cylinder 4 to the vaporization chamber 9 is complicated, and there are many connecting parts, so there are problems such as poor assembly and failure to ensure a secure seal. .

OBJECTS OF THE INVENTION The present invention solves these conventional problems and provides a steam iron having a structure for supplying water to a vaporization chamber, which is simple in construction, and has improved assembly and sealing properties.

Composition of the Invention The steam iron of the present invention includes a base having a vaporizing chamber;
A tank installed on the base, a sealing member fitted into the bottom of the tank to form a water passage that connects the tank and the vaporization chamber in a watertight manner, and a seal member that connects the tank and the vaporization chamber in a watertight manner to form a water passage, and the water in the tank is passed through the water passage to the vaporization chamber. A part of the sealing member is installed in the tank and combined with the water supply device, so that the structure for conveying the water in the tank to the vaporization chamber is simple and easy to assemble. This improves the properties and sealing properties.

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

In FIGS. 2 to 4, reference numeral 2o denotes a vaporization chamber 21 and a base that communicates with the vaporization chamber 21 and forms a steam outlet 22, in which a heater 23 is embedded.

The upper end of the vaporization chamber 21 has a vaporization chamber lid 24 having an opening hole 24a.
covered with. 25 is a base cover made of heat insulating material;
Reference numeral 26 designates a handle that forms a tank portion 27 together with the base cover 26, and a steam control mechanism 29 and a water supply device 30 consisting of a pump are provided within the operating range of the hand holding the grip portion 28. The steam control mechanism 29
This is a well-known method that controls the amount of water in the tank section 27 dripping into the vaporization chamber 21 by opening and closing a nozzle. The water supply device 30 functions to suck water from the tank portion 27 and supply it to the vaporization chamber 21, and its configuration is as follows.

That is, 31 is a cylinder formed integrally with the handle 26, and a suction channel 32 extending into the tank portion 27 is formed at the lower end of the cylinder. Seal member 54 via water pipe 33
A water supply channel 35 connected to each is integrally provided. The water pipe 33 and the seal member 34 are integrally constructed. 36 is a check valve made of a steel ball provided in the cylinder 31 at the upper end of the suction channel 32, and 37 is a piston made of an elastic material such as rubber and slidably provided in the cylinder 31. The sealing member 34 has a concave portion 34a in a part thereof, and is press-fitted into an opening hole 38 provided in the base cover 26 that forms the bottom surface of the tank portion 27, with the lower portion extending outward from the tank portion 27. It stands out.

The sealing member 34 seals the base cover 25 on the bottom of the tank 27 and the vaporization chamber 2/1 watertight to form a water passage, which is connected to the water pipe 33.

The protrusion of the seal member 34 is compressed by the base cup (-25) and the vaporization chamber lid 2-4, thereby communicating the water pipe 33 and the vaporization chamber 21. Also, the base cover 25 and the seal member 3
Base cover 2 is installed to improve the sealing performance of the mating part with 4.
The wall thickness A of the opening hole 38 portion of No. 5 and the dimension of the groove 3 of the grooved portion 34a of the sealing member 34 have the relationship A)B.

To explain the operation in the above configuration, when the piston 37 is raised when the amount of steam is increased during ironing work, the water in the tank portion 27 is absorbed into the cylinder 31 through the suction channel 32. Next, when the piston 37 is lowered,
The water in the cylinder 31 is fed into the vaporization chamber 21 through the opening hole 24a via the water supply pipe 33 which is the water supply channel 35 and the sealing member 34, and is vaporized there and the increased amount of steam is pumped through the steam outlet 22. It is squirted. In this way, tank part 2
By attaching the sealing member 34 integrally provided to the opening hole 3 on the bottom of the tank part 27 so as to protrude outward from the inside of the tank part 27, the number of fitting parts that are difficult to seal is reduced, and the tank part 27 The fitting between the seal member y and the seal member y is also reliable, and the sealing performance can also be improved. Also, the sealing member 34 is attached to the tank portion 2.
It is only necessary to press fit into the opening hole 38 of No. 7, and the assembly efficiency can be improved.

FIG. 5 shows the dimensions of another embodiment of the present invention, in which a sealing member 42 is attached to an opening hole 41 provided in a base cover 40 on the bottom of the tank section via a fixing plate 43.
By configuring the outer diameter of the protruding portion of the seal member 42 so that C>D with respect to the inner diameter C of 1, the seal member 42 can be easily inserted into the opening hole 41, and the ease of assembly can be improved. In addition, the difference between the dimension E, which is the sum of the wall thickness of the base cutter (-40) and the plate thickness of the fixing plate 43, and the groove dimension F of the concave portion of the sealing member 42 can be made large, and the compression dimension can be increased by machining. Therefore, the sealing performance between the tank part and the seal member 42 is improved, and by attaching the seal member 42 via the fixing plate 43,
Even if it is compressed with the vaporization chamber cover 44, it can be fixed more reliably.

FIG. 6 shows still another embodiment of the present invention,
A water supply pipe 46 is provided integrally with a water supply pipe 45 below the side wall of a cylinder 44 provided integrally with the handle 26, and the water supply pipe 45 is constructed by connecting it to a sealing member 47 formed of a flexible material. By compressing the seal member 47 with the base cover 46, the base cover 48 on the bottom of the tank, and the vaporization chamber lid 49, the sealing performance is further improved and the fixation of the seal member 4γ is also made stronger.

Effects of the Invention As is clear from the above embodiments, the steam iron of the present invention is equipped with a water supply device that supplies water in the tank to the vaporization chamber via a sealing member that seals the tank and vaporization chamber watertight. The above sealing member is partially installed inside the tank, and the other part protrudes outside the tank and is fitted into the bottom of the tank, thereby simplifying the water supply structure to the vaporization chamber. Moreover, the number of fitting locations of the water supply channel can be reduced. Therefore, the fitting between the tank and the sealing member is reliable, and a steam iron with excellent sealing performance and ease of assembly can be provided.
