Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a steam iron with a spray device equipped with an electric air pump.

Conventional Structure and Problems Conventionally, this type of steam iron with a spray device has a structure as shown in FIG. 1, in which the steam generation function and the spray generation function are realized by separate devices. That is, 1 is a tank for storing water, and 2 is a steam button provided on the top of the tank 1. By operating the steam button 2, the opening/closing rod 3 can be moved up and down.

Reference numeral 4 denotes a valve attached to the tip of the opening/closing rod 3, which opens and closes the water dripping hole 6 of the nozzle 5 provided at the bottom of the tank 1. 7 is nozzle 5
In the vaporization chamber provided in the base below, water dripped from the tank 1 through the nozzle 5 is vaporized and ejected as steam through a steam hole (not shown) on the back of the base. 8 is a spring that biases the opening/closing rod 3 upward, and 9 is a spray cylinder fixed to the bottom of the tank 1, which has an inlet 10 and a ball valve 11 at the bottom. 12 is a piston fitted into the spray cylinder 9 and has a water passage 13 formed therein; 14 is a spray button mounted above the piston 12 via an operating rod;
15 is a spray nozzle fixed to the front part of the iron, which is connected to the water passage 13 of the piston 12 through a connecting tube 16, and when spray is generated, the water in the tank 1 is sprayed into the spray nozzle 9. Water passage 13 of piston 12. It is atomized and sprayed through the connecting tube 16 by nine spray nozzles 15.

Since the tank 1 has many members in this way, it is subject to large spatial restrictions and the assembly work is also complicated. In addition, when ironing requires a large amount of spray, the spray button 14 must be repeatedly operated, which is very inconvenient;
is located close to steam button 2, so spray button 1
4 was difficult to operate.

OBJECTS OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object thereof is to provide a steam iron with a spray device that is easy to assemble and is very easy to use.

Structure of the Invention In order to achieve the above object, the present invention includes a base having a vaporization chamber, a tank and a handle arranged on the base, an electric air pump provided in the handle, and an air tube connected to the electric air pump. and a spray device connected to the tank via a water guide tube, the spray device being movably configured to selectively supply spray to the vaporization chamber or the outside of the tank. This is what I did. Therefore, one tin device can perform the functions of supplying water to the vaporization chamber and generating steam, and the function of atomizing the spray outward.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings. In FIGS. 2 and 3, reference numeral 11 denotes a base in which a heater 12 is embedded, and a vaporization chamber 13 is formed inside. Reference numeral 14 denotes a handle provided above the base 11, and a removable tank 15 is provided at the front. 16 is an electric air pump provided inside the handle 14; 17 is a partition plate 18 on the top of the tank 16;
A spray device is movably provided and partitioned from the lower part of the waste tank 15, and rotates around a fulcrum 19. 2o is a water supply pipe extending downward to operate the spray device 17 with a changeover switch slidably provided on the top surface of the tank 15; A backing 22 is arranged on the backing 22. 23 is a spray hole provided in the outer wall of the tank 16 in front of the spray device 17;
is an air tube connected to the electric air pump 16, 2
6 is an air tube connected to the upper end of the spray device 17, and both air tubes 24 and 26 are connected to the front wall 26 of the handle 14.
and a joint 28, 29 provided through the rear wall 27 of the tank 15. 3o is a water guide tube with one end connected to the spray device 17 and the other end placed at the bottom of the tank 15; 31 is a partition plate 18 at the top of the tank 15;
The air tube 25 and the water guide tube 30 are passed through the through hole opened in the tank 16 through the rubber bushing 32 and the like to close the tank 16 watertightly. 33 is a switch for controlling the electric air pump 16 provided on the grip 9 of the handle 14, and 34 is a conductor connecting the switch 33 and the electric air pump 16.

Next, the structure around the spray device 17 will be explained in detail with reference to FIG. The spray device rotatably mounted on the fulcrum 19 has a longitudinal groove 36 on its side surface, into which the tip 2ob of the operating arm 20a of the changeover switch 20 engages. Further, a locking arm 36 having elasticity is formed at the upper part of the operating arm 20a, and a convex portion 37 is provided at the tip of the locking arm 36. By engaging with and 39, the changeover switch 20 is positioned. When the convex portion is engaged with the concave portion 38, the tip portion 20b of the operating arm 20a is located at the upper end of the groove portion 35, and the tip of the spray device 17 faces downward, as shown in Figure 8 (8). The water supply pipe 21 and the spray device 17 are directly connected by contacting the water supply pipe 21 and the spray device 17.When the convex part 37 is engaged with the concave part 39, the tip part 20b of the operating arm 20a is connected to the groove 36 in the same figure (as shown by the arrow B). The tip of the spray device 17 faces outward from the spray hole 23 of the tank 15. The distance a between the recesses 38 and 39 is determined by the operating stroke of the spray device 17 and the groove 3.
It is determined as appropriate depending on the length of 5, etc.

Next, the configuration of the electric air pump 16 will be explained with reference to the drawings. In FIG. 4, 40 is an excitation coil provided in the electric air pump 16, and 41 is an excitation coil 4 at the tip.
This is a vibrating rod to which a permanent magnet 42 is attached facing 0. 4
3 is a pump part provided at the bottom of the electric air pump 16;
It has a diaphragm 44 connected to a vibration rod 41 at the top,
Intake chamber 45 at the bottom. The exhaust chambers 46 are arranged in rotation.

47 is an air intake pipe attached to the intake chamber 45, 48 is a check valve, 49 is an air discharge pipe attached to the exhaust chamber 46, 5
0 is a check valve. ! ! The above-mentioned air tube 24 is connected to the tip of the air discharge pipe 49. FIG. 4 shows another embodiment of the electric air bong 16, in which a small DC motor 51 is used in place of the excitation coil 40 in FIG. The other configuration is the same as that shown in FIG. 3, with a variable eccentric shaft 62.

When it is desired to generate steam in the above configuration, by sliding the changeover switch 20 backward, the spray group #17 communicates with the vaporization chamber 13 via the water supply pipe 21. Here, when the electric air pump 16 is energized by the switch 33, the excitation coil 40 or the small DC motor 61 is energized, which causes the diaphragm 44 to vibrate and the electric air pump 16 to operate. And this electric air pump 16
The air sent out is sent to the spray device 17 through the air tubes 24 and 25, and the spray device 17 sucks water from the tank 15 through the water guide tube 30 and blows out a spray toward the vaporization chamber 13. Heater switch 5
The spray vaporized in the vaporization chamber 13 by the heat of the heater 12 energized by the heater 12 becomes steam and is ejected from a steam hole (not shown) provided on the back surface of the base 11. However, when spraying is required, by sliding the changeover switch 2o forward, the spray device 17 rotates forward, and its tip faces outward from the spray hole 2.3 of the tank 16. When the switch 33 is turned on and the air pump 16 is energized, spray is sprayed from the tip of the spray device 17.

In this manner, the spray device 17 functions to supply water to the vaporization chamber 13, and also functions to spray by simply operating the switch 20, making the structure inside the tank 15 simple and easy to assemble. Further, since the electric air pump 16 sends air to the spray device ff117 and sprays air, ironing can be done easily.

Effects of the Invention As is clear from the above embodiments, according to the present invention, the spray device has both the function of supplying water to the vaporization chamber and the function of atomizing the spray, making it easy to assemble and very convenient to use. A steam iron can be provided.
