Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a pump device for an iron with a spray mechanism or an iron with a steam increasing mechanism for use in general households.

Conventional structure and its problems Conventional systems equipped with a spray mechanism or an increased steam mechanism (a mechanism that temporarily ejects a larger amount of steam than is normally used; hereinafter referred to as increased steam) The structure of the steam iron will be explained with reference to FIGS. 1 and 2. First, in a steam iron with a steam increasing mechanism, as shown in Fig. 1, when the piston 2 is raised via the external operator 1, water in the tank 3 flows into the cylinder through the suction channel 4, and then, When the piston 2 is lowered, the check valve 6 closes the suction channel 4, and therefore, the water in the cylinder 5 is supplied to the steam vaporization chamber 10 provided in the base 9 via the water supply channel 7 and the water supply pipe 8 for increasing steam. be done.

Next, if you have a steam iron with a spray mechanism,
As shown in FIG. 2, in the same way as the above-mentioned operation for increasing the amount of steam, by lowering the piston 2, the water flowing into the cylinder 5 is transferred to the spray nozzle 13 via the water supply channel 7 and the water supply pipe 11 for the spray mechanism. It was designed to be supplied to However, the conventional configuration had the following drawbacks.

In other words, in the case of a steam iron with a steam increasing mechanism, one of the two outlets 15 provided in the water supply section 7 is made into a nested structure in the mold and buried at the time of molding, as shown in FIG. Although not shown in the figure, it was necessary to use a separate part (such as a rubber gasket) to block the outlet.

Next, in the case of a steam iron with a spray mechanism,
In order to block one of the two outlets 16, plug 1 is inserted as shown in FIG.
4 was required.

As described above, in the conventional configuration, as shown in Figs. 3 and 4, there are two types of pump parts with different shapes: one for a steam iron with a steam increasing mechanism and the other for a steam iron with a spray mechanism. This requires a mechanism and has problems in terms of switching loss and management during production. Furthermore, since irons with a spray mechanism absolutely require two parts, they also have the disadvantage of increasing the number of assembly steps. Temporarily again.

As a method of combining the above-mentioned two types of pump mechanism into one type and achieving advantages in terms of production management, it is conceivable to unify the shape into one for a steam iron with a spray mechanism as shown in Fig. 4. However, in this case, when a steam iron with a steam increasing mechanism is used, a stopper is required to close the outlet 15, and this poses the same assembly problem as a steam iron with a spray mechanism.

Furthermore, when used as a steam iron with a spray mechanism, the outlet hole diameter of the spray nozzle 13 is generally very small, φ0.3 to 0.58, so the water pressure in the water supply channel 7 becomes very high. The plug 14 is pushed by the water pressure and is easily removed, and there are also problems such as taking measures to prevent the plug 14 from being removed by using other parts.

OBJECTS OF THE INVENTION The present invention provides a pump device that eliminates such conventional drawbacks, improves productivity, and realizes a spray mechanism and a steam increasing mechanism that are easy to assemble at low cost. It is.

Structure of the Invention The iron pump device of the present invention includes a cylinder having a water supply section having two outlets and a suction channel for sucking water in the tank, a piston slidably provided in the pudding mite, and the same. It is equipped with an external operator for operating a piston, and a water pipe having one end formed with a contact part that is detachably connected to the water supply section, and the outlet of the water supply section is connected to the water supply pipe to the water supply section. The water in the cylinder can be sprayed by simply selecting the direction in which the water pipe is connected to the water supply section, using a pump device with the same shape and a water pipe that can be selectively opened and closed depending on the direction. Alternatively, it can be supplied for increased steam use.

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

5 to 7 show the case of a steam iron with a steam increasing mechanism 721, and 17 is a vaporizing chamber 18 and a base that communicates with the vaporizing chamber 18 and forms a steam outlet 19, in which a heater 20 is embedded. There is.

21 is a base cover made of a heat insulating material, 22 is a handle that forms the tank part 23 together with the base cover 21, and a steam control mechanism 26 and a pump device 26 are provided within the operating range of the hand that grips this grip part 24. It is. The steam control mechanism 25 is a well-known mechanism that controls the amount of water dripping into the vaporization chamber 18 from the tank section 23 by opening and closing the nozzle 27'. The pump device 26 has the function of sucking water from the tank portion 23 and feeding it to the vaporization chamber 18, and its configuration is as shown below.

That is, 27 is a linder that is integrally molded with the handle 22, and a suction channel 28 that extends into the tank portion 23 from its lower end.
However, as shown in FIG. 6, the lower peripheral wall is provided with a water supply section 29, and each water supply section 29 has a hole 30 for a steam iron with a spray mechanism and a hole 30 for a steam iron with a steam increasing mechanism. A hole 31 used for this purpose is formed.

Now, in the case of a steam iron with a steam increasing mechanism, as shown in Fig. 7, the water supply pipe 32 is connected to the hole 3.
Sesotona kudzu is placed in the water supply section 29 so that it is in the o direction. In this case, since the connecting portion 33 of the water pipe 32 is designed to close the hole 31 for use in a steam iron with a spray mechanism, there is no need to use a separate part to close the hole 31. The second water supply pipe 32 is then connected to the vaporization chamber 18 provided in the base 17. Reference numeral 34 indicates an external operating element of the piston 35 made of an elastic body such as rubber that is slidably provided in the cylinder 27, 36 indicates a check valve made of a steel ball, and 37 indicates a spring for returning the external operating element 34. ing.

The operation for performing increased steam in the above configuration will be explained. In order to simplify the explanation of the operation, the explanation will be given from the moment when the external operator 34 is lowered.

When the lowering blade is removed, the piston 35 rises due to the action of the spring 37. Correspondingly, the check valve 36 opens, and the water in the tank section 23 is sucked into the 7 cylinder 27 through the suction channel 28. Next, when the external operator 34 is lowered against the spring 3 and the piston 35 is lowered at the same time, water in the cylinder 27 flows through the water pipe 32 to the vaporization chamber because the check valve 36 is closed. 18, the amount of steam generated in the vaporization chamber 18 is increased by the amount supplied by the pump group ++'i 26, and the steam is ejected [ ] 19
It is something that is gushing out more. The above is the case where the steam is used for increasing the amount of steam.

Next, FIGS. 8 and 9 show the case of a steam iron having a spray mechanism. The steam control mechanism 25 and pump device 26 themselves are exactly the same as in the case of a steam iron with a steam increasing mechanism. Now, in the case of a steam iron having a spray mechanism, the water supply pipe 32 is set on the hole 31 side of the water supply section 29. In this case, water pipe 3
Since the second connecting portion 33 closes the other hole 30, there is no need to use a separate part to close the same size 30. Now, the outlet of the water pipe 32 is connected to a spray nozzle 38 mounted on the front part of the pusher 22.

In the above configuration, the operation when ejecting a spray will be explained from the state in which water is sucked into the cylinder 27.

When the piston 35 is lowered against the spring 37, the water in the cylinder 27 is supplied to the spray nozzle 38 via the water pipe 32 because the reverse valve 36 is closed.
It is sprayed.

The above is the configuration and operation of a switchable pump device for a steam iron having a steam increasing mechanism and a steam iron having a spray mechanism. .

Effects of the Invention As described above, according to the present invention, it is possible to construct two types of irons, an increased steam iron and an iron with a spray, by using a pump device of the same shape and a water pipe of the same shape.

This eliminates the need to use different pump device shapes and water pipes for each model, which was a drawback in the past, improving productivity and management. Since it can be constructed, it is possible to provide a mechanism that is low cost and easy to assemble. In addition, since the water supply valve has a connection part, even if the water pressure is high, it will not leak out from the water supply part, and unlike conventional methods, there is no need to take preventive measures when removing the tap.
l, has a length of 1.
