Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a steam iron with a removable tank equipped with an electric air pump.

Conventional Structure and Problems Recently, a steam iron has been invented in which an electric air pump is used as a means for dropping water into the vaporizing chamber or as a means for supplying water to a spray nozzle.

In other words, the spray device receives air from an electric air pump through an air tube, etc., sucks up water from inside the tank through the water guide tube, drops water into the vaporization chamber, or supplies water to the spray nozzle. .

However, if you try to apply an electric air pump like this to a steam iron with a removable tank, there will be a problem with the treatment of the air tube at the joint between the removable tank and the handle, and the air will flow out from the air tube. Spray equipment did not operate efficiently due to leaks, etc.

OBJECTS OF THE INVENTION The present invention was made in order to solve the above-mentioned conventional problems, and its purpose is to fully utilize the functions of an electric air pump and a spray device.

Structure of the Invention In order to achieve the above objects, the present invention comprises: a base having a vaporization chamber; a handle having a built-in electric air pump; and two pipes connected to the spray device, and a first joint and a second joint that are attached to the other ends of these pipes and can be disconnected from each other. This allows air to be efficiently sent from the electric air pump to the spray device.

Description of examples Embodiments of the present invention will be described below with reference to the drawings.

I will clarify. In FIG. 1, 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 tank 15 is detachably attached to the front of the handle 14. 16 is an electric air pump installed in the handle 14, 17 is a spray device fixed to the water partition plate 18 at the top of the tank 16, and 19 is a water supply provided by penetrating the tank 15 from the bottom of the spray device 17 in a watertight manner. It's a pipe, and the bottom end of it is 2
It communicates with the vaporization chamber 13 via 0. 21 is a pipe connecting the electric air pump 16 and a first joint 22 made of a heat-resistant rigid body or metal, which is attached through the front lower side wall of the handle 14; 23 is the spray device 17 and the rear lower side wall of the tank 15; These pipes 21 and 23 connect the tank 15 to the handle 14 and the second joint 24 made of elastic heat-resistant rubber or the like.
When attached to the first and second joints 22°24
The electric air pump 16 and the spray device 17 are connected by airtight fitting. 26 connects one end to tank 1
A water guide tube 26 disposed at the bottom of 6 for supplying water to the spray device 17 is a switch for controlling the electric air pump 16 and is connected to the electric air pump 16 by a conductor 27. 28 is a heat insulating plate attached to the lower surface of the handle 14, and 29 is a locking member for locking the tank 15, which is provided at the front of the upper surface of the handle 14.

Next, the configuration of the electric air pump 16 will be explained with reference to the drawings. In FIG. 2, 3o is an excitation coil 31 provided inside the electric air pump 16, and an excitation coil 31 is attached to the tip of the excitation coil 31.
This is a vibrating rod to which a permanent magnet 32 is attached facing 0. 3
3 is a pump part provided at the bottom of the electric air pump 16;
It has a diaphragm 34 connected to a vibration rod 31 at the top,
Intake chamber 35 at the bottom. Each exhaust chamber 36 is fixedly provided.

37 is an air intake port attached to the intake chamber 36, 38 is a check valve, 39 is an air discharge port attached to the exhaust chamber 36, and 4o is a check valve. Further, the above-mentioned pipe material 21 is connected to the tip of the air discharge port 39. Figure 3 shows another electric air pump 16
This is an embodiment in which a small DC motor 41 is used instead of the excitation coil 30 in FIG. -C1 The other configurations are the same as shown in FIG.

When using the team iron with the above configuration, turn on the heater switch 43, turn on the heater 12, and then switch 2.
When the switch 9 is turned on, the excitation coil 3° or the small DC motor 41 is energized, which causes the diaphragm 34 to vibrate and the electric air pump 16 to operate. The air sent out from this electric air pump 16 is then transferred to the pipe material 21.
, 23, enters the spray device 17 from the upper end, and is blown out from the spray tip 44. At this time, the vicinity of the spray tip 44 becomes negative pressure, so the water in the tank 15 is sucked into the spray device 17 through the water guide tube 25, and the air blown out from the spray tip 44 contains atomized water droplets. . Here, the negative pressure near the spray tip 44 is always constant, and the amount of moisture contained in the air is always constant. This air containing a certain amount of mist-like water droplets is led to the vaporization chamber 13 through the water supply pipe 19. The vaporization chamber 13 has already been heated by the heater 12, and the moisture turns into steam and flows into the base 1.
The steam is ejected from a steam hole (not shown) drilled in the bottom of 1.

Further, another embodiment will be explained based on FIG. 6. Reference numeral 46 indicates a hole drilled at the rear of the heat insulating plate 28 for passing the pipe material 2, and 46 indicates a hole for passing through the front part of the heat insulating plate 28. A first joint 47 made of a rigid body penetrates the bottom of the tank 15 and is airtightly fitted with a second joint 47 made of an elastic body which is attached watertight.

When the tank 16 is attached to the handle 14, the first and second joints 46 and 47 are connected to the pipe material 21 and the pipe material 23.
to connect the electric air pump 16 and the spray device 17. The other configurations and operations are almost the same as the first embodiment.

In this way, the pipe material 21 connected to the electric air pump 16
The first joint 22 connecting pipe 46 attached to the tip of the pipe 22 and the second joint 24 or 47 attached to the tip of the pipe 23 connected to the spray device 17 are made of a rigid body and an elastic body. By joining the joints, the pipe material 21 and the pipe material 23 are airtightly connected, and the air from the electric air pump 16 can be efficiently sent to the spray device 17.The mounting positions of the first and second joints are as follows. As shown in the embodiment, the handle 14 is not limited to the lower part of the tank 16. For example, a first joint is provided in front of the grip part of the handle 14, and a second joint is provided at the position of the tank 15 opposite to this. A joint may be provided. Furthermore, the tubes 21 and 23 do not have to be separate members, and can be used for the electric air pump 16 or the spray device 17.
It may be formed integrally with.

Effects of the Invention As is clear from the above embodiments, the present invention allows the pipe material to be freely interrupted by the first and second joints, so air can be efficiently sent from the electric air pump on the handle side to the spray device on the tank side. It is something that can be done.
