Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a steam iron with a detachable water tank.

A steam iron with a removable water tank combines a dripping nozzle installed at the bottom of the water tank with a connecting packing that leads to the vaporization chamber in the base, and water from the water tank is dripped into the vaporization chamber from the dripping nozzle, generating electricity inside the vaporization chamber. Generally, the steam passes through a steam passage in the base and is ejected from a steam hole on the bottom of the base.

This method is called a pure dripping method and has a simple structure, but the amount of water dripped must be controlled by the diameter of the dripping nozzle, and is generally 0.6 to 0.7 Tn! Since the nozzle diameter is n, it is easy to get clogged with dust, etc., and the dripping tends to stop or become unstable. When the water level in the water tank goes down, the amount of dripping water decreases and the amount of steam also decreases. Furthermore, when the base temperature is insufficient for vaporization, if you accidentally raise the steam button and drop water, the water may flow out from the steam hole without being vaporized. The present invention has been devised to address such problems, and will be described below with reference to drawings showing an example of implementation.

In the figure, 1 is a base that integrally houses a sheathed heater 2, and has a vaporization chamber 3 inside. A boiler 5 is attached to the bottom of the water tank 4 installed on the front end of the base 1 with screws 6.
The boiler 5 is always urged downward by a spring 7 fitted onto the screw 6. When the water tank 4 is installed on the base 1, the flat bottom of the boiler 5 is pressed downward by the spring 7. This brings it into close contact with the flat surface portion 8 of the base 1.
The water tank 4 and the boiler 5 communicate with each other via a check valve 9 provided at the bottom of the water tank 4 and a connecting packing 10 provided on the boiler 5. The lower end of a connecting member 12 is connected to the boiler 5 via another connecting packing 11, and the upper end of the connecting member 12 is supported by the bottom of the water tank 4 and communicated with a delivery pipe 13. Reference numeral 14 denotes a steam button that protrudes from above the water tank 4. When the steam button 14 is raised and the opening/closing rod 15 is pulled up, the water in the water tank 4 passes through the check valve 9 and enters the boiler 5 and connects the connecting member 1.
2 and extends upward within the water tank 4 to the same water level as the water tank 4.

The water in the boiler 5 is heated by the heat transferred from the flat surface part 8 of the base 1, and when it partially boils, the movable valve 9a in the check valve 9 is pushed upward by the steam pressure. Close check valve 9. When the check valve 9 closes, the steam in the boiler 5 tries to push out toward the delivery pipe 13, thereby pushing up the water in the reboiler 5 and the delivery vibe 13. The pushed up water enters a reservoir 17 located above the water surface in the water tank 4 at an intermediate portion between the sending vibrator 13 and the dripping vibrator 16. A small hole 17 is formed on the upper surface of the reservoir 17.
a is provided, and the water sent to the reservoir 17 naturally drips to the dripping vibrator 16 side. The lower end of the dripping vibrator 16 communicates with a connecting member 18 supported at the bottom of the water tank 4,
Further, the lower end of this connecting member 18 is connected to a connecting packing 19 installed in the base 1 so as to communicate with the upper end of the vaporizing chamber 3, so that the dripping vibrator 16 communicates with the vaporizing chamber 3, and the liquid is sent from the dripping vibrator 16. The water is vaporized in the vaporization chamber 3, and the generated steam passes through a steam passage 20 and is ejected from a steam hole 21 provided at the bottom of the base 1. When the steam inside the boiler 5 pushes water into the vaporization chamber 3 and the pressure inside the boiler 5 decreases, the check valve 9 opens and the water flows into the boiler 5 into the tank 4.
of water flows into the vaporization chamber 3, and in the process described above, the water drips into the vaporization chamber 3 one after another to generate steam. In the figure, 22 is a lock button, and 23 is a handle. Therefore, the present invention uses a so-called bubble pump made up of the check valve 9 and the boiler 5 to once push the water above the water surface and then drip it into the vaporization chamber 3, so a small-diameter dripping nozzle is used as in the conventional method. The dripping becomes stable.

Further, the amount of water sent out from the boiler 5 is determined by the amount of heat transferred from the base 1 to the boiler 5. In other words, the temperature of the base 1 determines the amount of water sent out from the wheeler 5 and, by extension, the vaporization capacity in the vaporization chamber 3, so the boiler 5
By matching the amount of water sent out from the base 1 with the vaporization capacity of the vaporization chamber 3, even if the temperature of the base 1 changes, water will not drip more than the vaporization capacity of the vaporization chamber 3 and cause water leakage from the steam hole 21. do not have. Therefore, even if the steam button 14 is raised by mistake when the base temperature is insufficient for vaporization, water will only enter the boiler 5 and the delivery vibe 13 and will not be sent to the vaporization chamber 3, preventing water leakage. It doesn't even wake me up. Also, since the flat bottom surface of the boiler 5 is brought into close contact with the flat surface portion of the base 1 by the spring 7, the boiler 5 is moved from the base 1.
The heat transfer to the tank 4 is improved and stable, and the amount of water delivered is always stable, so even if the water level in the water tank 4 changes, the amount of steam does not change. The steam iron of the present invention can be implemented as described above, and can solve the problems of conventional steam irons with a removable water tank, and has a structure in which the boiler is always airtight with the base, allowing water to flow into the vaporization chamber. Its effects are great, such as being able to send it in a stable state.
