Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a steam iron that can appropriately jet steam from the lower surface of a base.

[Conventional technology]

This type of steam iron has a handle and a water tank on the base of the iron. A vaporizing chamber is formed on the upper surface of the base, and a valve mechanism is provided at the bottom of the water tank, and the water tank is connected to the vaporizing chamber via this valve mechanism.

Further, the water tank is provided with a steam selection operation body for opening and closing the valve R structure, and the handle is provided with a temperature setting operation body for setting the base UIU.

Therefore, when the temperature of the base is set to a high temperature by operating the temperature setting controller, and in this state the valve mechanism is opened via the steam selection controller, the water in the water tank flows into the vaporization chamber of the base. The water is dripped in sequence, and this water is vaporized by the heat of the base and becomes steam, and this steam is sequentially ejected from the bottom of the base toward the bottom. While applying this steam to the fabric, the base brushes the fabric. It is something.

[Problem that the invention seeks to solve]

By the way, when using an iron with steam ejected from the bottom of the base, it is necessary to always set the base to a high temperature. Once dripped, it is difficult to vaporize the water sufficiently, resulting in water remaining in the vaporization chamber and causing problems such as leakage from the bottom surface of the base. For this reason, conventionally, when attempting to eject steam from a state where the base temperature is set to medium or low temperature, the base temperature must be set to high temperature by operating the temperature setting operation body. After this, the operator must operate the steam selection controller, which requires a two-step operation, which makes the work cumbersome and troublesome, and the operator often forgets to operate the temperature setting controller. However, there is a problem in that water is dripped into the vaporization chamber while the base is at medium or low temperature, causing the above-mentioned inconvenience. This invention aims to solve these problems.

[Means for solving problems]

In order to solve these problems, the present invention includes a base facing a heater, a temperature setting operation body for setting the temperature of the base, a vaporizing chamber formed in the base, and a vaporizing chamber formed in the vaporizing chamber. comprising a water tank connected via a valve mechanism and an operating body for steam selection that opens and closes the valve mechanism,
The valve mechanism is opened via the steam selection operation body, and this opening causes the water in the water tank to drip into the vaporization chamber of the base, and this water is vaporized by the heat of the base and turned into steam. A detection mechanism that detects the opening of the valve mechanism, and a setting state of the operating body for setting the temperature by controlling the energization of the heater in response to the detection, and adjusting the temperature of the base. An energizing ikQ 111 circuit is provided to maintain the steam generation at an appropriate temperature regardless of the temperature.

[Effect]

When the valve mechanism opens, it is detected by the sensing 1tH. Upon this detection, the temperature of the base is maintained at the appropriate humidity for steam generation by the energization control circuit, regardless of the operation status of the temperature setting operation body, and therefore, as the valve mechanism opens, water drips from the water tank into the vaporization blank. Always vaporize properly.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

1 in the figure is a base, a heater 2 is embedded in this base 1, and a vaporization chamber 3 is formed on the upper surface of this base 1.
is connected to. A handle 6 and a water tank 7 are provided on the base 1, and the vaporization chamber 3 is provided at the bottom of the water tank 7.
A valve mechanism 8 is provided opposite to the valve mechanism 8 , and the water tank 7 is connected to the vaporization chamber 3 via the valve mechanism 8 . This valve mechanism 8
is composed of a water injection hole 9 formed in the water tank 7 and a needle valve 10 attached to the water injection hole 9. An operating body 11 connected to the needle valve 10 is provided at the upper end of the water tank 7, and the valve mechanism 8 is opened and closed by operating the operating body 11 up and down. Operation body 11
A detection switch 12 is attached as a detection m1fi,
This detection switch 12 detects when the operating body 11 is depressed downward, that is, when the valve mechanism 8 is opened.

An operating body 14, for example, a rotary dial type, for setting the temperature is provided in the middle part of the handle 6. By rotating the operating body 14 and adjusting it to a predetermined position, the temperature of the base 1 can be adjusted by rotating the operating body 14. It is possible to set a predetermined temperature depending on the position, for example, high temperature, medium temperature, or low temperature. A position detection element 15 is provided near the operating body 14 to detect its rotational position, that is, the temperature setting state with respect to the base 1. Further, a temperature detection element 16 such as a thermistor is attached to the base 1 to detect the temperature of the base 1.
An energization control circuit 7 is installed roughly inside the rear end of the handle 6.

The energization dust control circuit 17 includes a microcomputer 18, as shown in FIG.
The detection switch 12, position detection cable 15, temperature detection element 16, and heater 2 are connected to 8. In addition, 1
1 is the temperature signal input circuit, 20 is the power 1liIII! It is one circuit.

Therefore, when the valve mechanism 8 is closed, the position detection cable 15 provides information on the setting state of the operating body 14 for temperature setting, and the temperature detection element 16 provides information on the actual temperature of the base 1. is input to the microcomputer 18,
Based on the judgment based on both information, the power supply to the heater 2 is controlled through the microcomputer 18, and this control maintains the temperature of the base 1 at a temperature corresponding to the setting of the temperature setting operation body 14.

When the steam selection operation body 11 is depressed downward in such a state, the detection switch 12 detects this. Through this detection, information on the operation of the operating body 11 is input to the microcomputer 18, and this input causes the microcomputer 18 to detect the temperature detection element 1 regardless of the setting state of the operating body 14 for temperature setting. 6
The base 1 is maintained at an appropriate temperature for steam generation by controlling the energization of the heater 2 while considering information from the base 1.

On the other hand, the valve mechanism 8 opens in response to the operation of the steam selection operation body 11, and with this opening, the water in the tank 7 flows into the valve F.
The liquid is sequentially dropped into the vaporization chamber 3 of the base 1 through the three tubes 8.

At this point, as shown in (e) above, the temperature of the base 1 is
Regardless of the setting, since the temperature is maintained at an appropriate temperature for steam generation, the water dropped into the vaporization chamber 3 quickly vaporizes into steam, and this steam is ejected from the ejection hole 5 through the guide path 4. In this way, steam can be spewed out without operating the temperature setting operating body 14 to a particularly high temperature setting position, that is, steam can be spouted by a single operation of the steam selection operating body 11. It is possible to use it conveniently.

In addition, in the above example of a physical store, a concave and convex dial type was used as an operating body for setting the temperature, but this may also be a push button type, and the location of the temperature setting operation body may be changed to the top of the handle. It is also possible to configure it so that it is provided on the end face and can be operated while holding the handle.

〔Effect of the invention〕

As explained above, according to the present invention, when water is dropped into the vaporizing chamber, the temperature of the base is maintained at an appropriate temperature for steam generation, regardless of the setting state of the operating body for temperature setting, and therefore the water is is always properly vaporized, and there is no possibility that water will remain in the vaporization chamber. Therefore, it is possible to reliably prevent water from leaking to the lower surface of the base.
