Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an iron with a spray for general household use.

Conventional structure and problems thereof Conventionally, in this type of iron with a spray, an opening 2 is provided on the front surface of an outer shell 1 constituting the iron, as shown in FIGS. Then, a nozzle body 5 having a water passage 3 and a male threaded portion 4 is inserted from the inside so that the male threaded portion 4 is exposed on the outside of the outer shell 1, and the male threaded portion 4 is
Generally, a spray nozzle 9 is constructed by screwing the female threaded part 6 into the male threaded part 3 of the nozzle body 5, and is fixed to the outer shell 1. It was hot. Further, in the space 10 formed by the nozzle body 5 and the nozzle head 8, a spherical check valve 11 and a core 13 having a guide groove 12 at the top for spouting water in a swirling state from the nozzle hole 7 are provided. Spring 1 biasing the check valve 11 and core 13
4, further comprising the outer shell 1 and the nozzle head 8.
A packing 15 was provided between the two to prevent water leakage.

However, in this configuration, the work procedure for attaching the spray nozzle 9 to the outer shell 1 is to insert the nozzle body 5 into the opening 2 of the outer shell 1, attach the packing 15 to the nozzle body 5, and then attach the core 13 inside the nozzle head 8. , the nozzle head 8 was screwed into the nozzle body 5 after inserting the spring 14 and the check valve 11, which was a time-consuming process.
This was due to the large number of parts constituting the spray nozzle 9 and the structure in which the spray nozzle 9 was assembled at the same time as the installation work. Furthermore, in the above configuration, since the spray nozzle 9 is assembled during the installation process as described above, assembly failures of the spray nozzle 9 are likely to occur, and especially when the torque when screwing the nozzle head 8 into the nozzle body 5 is small, packing may occur. 15 is not added between the outer shell 1 and the nozzle head 8, resulting in water leakage.

OBJECTS OF THE INVENTION The present invention solves these conventional problems, and provides a spray iron that facilitates the method of installing a spray nozzle, improves assembly workability, and stabilizes quality.

Structure of the Invention The spray iron of the present invention includes an outer shell constituting an iron main body, and an opening provided on the front surface of the outer shell that is inserted from the inside to project the front surface to the outside, and the water in the tank is sprayed into a mist. It has a completed spray nozzle connected to a pump device that ejects a jet of water, and is further provided with a support member for fixing the spray nozzle by abutting a part of the spray nozzle inside the iron body, With the above configuration, the spray nozzle can be attached to the iron body after inserting the spray nozzle from inside the opening of the outer shell.
Only the support member needs to be attached, resulting in improved assembly workability.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In Figures 3 to 4, 16
is the base with heater 7, 18 is the base 16
19 is a handle that together with this heat insulating plate 18 constitutes a tank 20; 21 is a pump device that sends water in the tank 20 to a spray nozzle 23 through a water conduit 22; 24 is a handle 19; This is a handle cover having a support member 25 placed on top of the spray nozzle 23 and in contact with the upper part of the spray nozzle 23. Further, the spray nozzle 23 has a spray hole 26
The spray nozzle 23 is formed by ultrasonic welding of a nozzle head 27 and a nozzle body 28, and is press-fitted into the opening 29 on the front surface of the handle 19 from the inside until the step 30 of the spray nozzle 23 comes into contact with the inner surface of the handle 19.

To explain the operation in the above configuration, when attaching the spray nozzle 23 to the iron, after connecting the spray nozzle 23 to the water pipe 22, the handle 19
When the stepped part 30 of the spray nozzle 23 is press-fitted from the inside until it contacts the inner surface of the handle 19 and the handle cover 24 is attached to the handle 19 with screws or the like, the support member 25 is sprayed. The spray nozzle 23 is fixed by contacting the upper part of the nozzle 23. Therefore, when the pump device 21 is operated to eject the water in the tank 20 from the spray nozzle 23, a force is applied to the spray nozzle 23 in the opposite direction to the press-fitting direction as a reaction force of the water ejection force. Spray nozzle 23
A force is generated in the direction in which the material comes out of the opening 29. However, since the spray nozzle 23 is press-fitted, it is difficult to come out from the opening 29, and since the spray nozzle 23 is fixed by the support member 25 of the handle cover 24 as described above, the spray nozzle 23 may come off or wobble. does not occur. Also, if the spray nozzle 23 is accidentally pushed inward from the outside of the handle 19, the spray nozzle 23
Since the spray nozzle 3 is fixed by the support member 25, the spray nozzle does not fall off.

In this way, the spray nozzle 23 can be easily and reliably fixed simply by press-fitting the spray nozzle 23 into the opening 29 of the handle 19 and fixing the handle cover 24 to the handle 19.

Furthermore, the nozzle head 27 and the nozzle body 28
Since the spray nozzle 23 can be assembled to the handle 19 after the spray nozzle 23 is completely attached by ultrasonic welding, water leakage from the spray nozzle 23 is eliminated, and quality can be improved.

FIG. 5 shows another embodiment of the present invention, in which reference numeral 31 denotes an iron body having a removable tank 32, the tank 32 having a tank body 34 having an opening 33 on the front, and a tank cover 36 having a support member 35.
It is formed by In this case, the spray nozzle 37 is press-fitted from the inside into the opening 33 on the front side of the tank body 34, and
The support member 35 of No. 6 presses and fixes the upper part of the spray nozzle 37. In short, the present invention only needs to have a structure that supports and presses the spray nozzle press-fitted into the opening of the outer shell from the inside.In other words, the supporting parts are not limited to the handle cover and the tank cover as described above. The effects of the present invention can be obtained even with screws and water inlet caps.

Effects of the Invention As is clear from the above embodiments, the iron with a spray according to the present invention is provided by inserting the completed spray nozzle connected to the pump device into the opening provided in the outer shell of the iron body from the inside. By making the front surface protrude to the outside and by fixing a part of the spray nozzle in contact with the inside of the iron body using a support member, the spray nozzle can be easily installed and fixed, improving the ease of assembly, and the spray nozzle itself Since it is attached to the iron body after completion of the process, variations during assembly do not affect the spray performance, and a spray device of stable quality can be obtained.
