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 pump.

Construction of conventional examples and their problems Recently, a steam iron using an electric air pump as a means for dropping water into the vaporizing chamber or as a means for supplying water to a spray nozzle has been invented.

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

However, if you try to apply such an electric air pump to a steam iron with a removable tank, the spray device is essential to the tank located at the front of the iron, so the electric air pump must also be installed in the tank. Although it is desirable to install an electric air pump and the structure is simpler, if the tank is removable from the iron body, this tank must be removed from the iron body when pouring and draining water, so if an electric air pump is attached to this tank, the tank itself will be damaged. There was a problem in that it became very heavy, making it inconvenient to handle when pouring water.

Purpose of the Invention The present invention was made in order to solve the above-mentioned conventional problems, and its purpose is to facilitate the handling of a removable tank equipped with a spray device driven by an electric pump during filling and draining. shall be.

Structure of the Invention In order to achieve the above object, the present invention includes an electric pump built into a handle for driving a spray device provided in a tank, and the electric pump and the spray device are detachably connected.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 11 denotes a base in which a heater 12 is embedded, and a vaporization chamber 13 is formed inside. 14 is a handle provided above the base 11;
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 15, 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 is a pipe, and its lower end communicates with the vaporization chamber 13 via a rubber bushing 20. 21
is a pipe material connecting the electric air pump 16 and a first joint 22 made of a heat-resistant rigid body or metal, which is attached to the front lower side wall of the handle 14;
Reference numeral 23 denotes a pipe material that connects the spray device 17 and a second joint 24 made of elastic heat-resistant rubber or the like and installed through the rear lower side wall of the tank 15. These pipe materials 21 and 23 connect the tank 15 to the handle 1
4, the first and second joints 2
2 and 24 are airtightly fitted to connect the electric air pump 16 and the spray device 17.
25 is a water guide tube whose one end is placed at the bottom of the tank 15 and supplies water to the spray device 17; 26 is a switch that controls the electric air pump 16;
It is connected to the electric air pump 16 by.
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, 30 is an excitation coil provided in the electric air pump 16;
has a permanent magnet 32 at the tip facing the excitation coil 30.
It is a vibrating rod with a . Reference numeral 33 denotes a pump section provided at the bottom of the electric air pump 16, which has a diaphragm 34 connected to the vibrating rod 31 at the top, and an intake chamber 35 and an exhaust chamber 36 at the bottom. 37 is an air intake port attached to the intake chamber 35;
8 is a check valve, 39 is an air discharge port attached to the exhaust chamber 36, and 40 is a check valve. Also, the air outlet 39
The above-mentioned tube material 21 is connected to the tip. Third
The figure shows an example of another electric air pump 16,
The excitation coil 30 in FIG. 2 is replaced by a small DC motor 41, and the vibrating rod 31 is replaced by an eccentric shaft 42 that converts the rotational motion of the rotating shaft of the small DC motor 41 into vibration. This is the same as shown in FIG.

When using the steam iron with the above configuration, turn on the heater switch 43 to energize the heater 12, and then turn on the switch 29 to turn on the excitation coil 30.
Alternatively, the small DC motor 41 is energized, thereby causing 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
3 and enters the spray device 17 from the upper end and is blown out from the spray tip 44. At this time, there is a negative pressure near the spray tip 44, so the water guide tube 2
5, the water in the tank 15 is sucked into the spray device 17, 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 is already equipped with the heater 1.
2, the moisture is turned into steam and is ejected from a steam hole (not shown) formed in the bottom of the base 11.

Further, another embodiment will be explained based on FIG.
A hole 46 for passing 1 is a first joint made of a rigid body that is attached to the front part of the heat insulating plate 28, and a second joint 47 is made of an elastic body that is attached to the bottom of the tank 15 in a watertight manner and penetrates the bottom of the tank 15. Fits airtightly. These first and second joints 46,4
7 is the pipe material 2 when the tank 15 is attached to the handle 14.
1 and the pipe material 23 to connect the electric air pump 16
and the spray device 17 are combined. The other configurations and operations are almost the same as the first embodiment.

In this way, the first joint 22 attached to the tip of the pipe 21 connected to the electric air pump 16
Alternatively, since one of the second joints 24 or 47 attached to the tip of the pipe 23 connected to the spray device 17 is made of a rigid body and the other is an elastic body, by joining these joints, the pipe 21 and the pipe 23 are airtightly connected so that 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 the handle 14 and the tank 1 as shown in the embodiment.
The first joint is not limited to the lower part of the handle 5, but for example, a first joint is provided in front of the grip part of the handle 14,
A second joint may be provided at a position of the tank 15 opposite to this. Furthermore, the tubes 21 and 23 do not need to be separate members;
Electric air pump 16 or spray device 17
It may be formed integrally with.

Effects of the Invention As described above, the present invention has an electric pump built into the handle that drives the spray device installed in the tank, and the electric pump and the spray device are detachably connected to the iron body of the tank. Since the electric pump and the spray device can be detachably connected at the same time as the electric pump and the spray device are attached and detached, erroneous operation can be prevented and the spray device can be driven reliably. Furthermore, since the tank does not have an electric pump, the tank can be made lighter, making it easier to handle when pouring water, and improving operability when attaching and detaching the tank. Furthermore, the amount of water stored in the tank by the electric pump does not decrease, making it possible to substantially increase the size of the tank.
