Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an iron for general household use.

Conventional structure and problems thereof Conventionally, in this type of iron, as shown in FIG. 2, on a base 2 having a heater 1,
A handle 6 is provided which is composed of a grip part 3 and a heat insulating part 4 and has an opening 5 at the rear, and the rear opening 5 of the handle 6 controls the power supply to the heater 1 protected by the outer shell member 7. An electronic control unit 8 was installed. The electronic control section 8 is composed of a plurality of electronic components 9 and a board 10. A removably provided water tank 11 is attached to the front of the handle 6, and this water tank 11
A water inlet 12 is provided in front of the handle 6, and the water inlet 12 is fixed to the handle 6 by a locking mechanism using a lock button 13 provided in front of the grip 3. The grip part 3 has a grip part body 14 and a grip part cover 15, and a lock button 13.
It was common to have it clamped and fixed.

However, with this configuration, when water is poured into the iron while it is standing on a free-standing surface, the water inlet 12 of the water tank 11
To remove more overflow water, press the lock button 13.
Then, it enters through the gap between the grip body 14 and the grip cover 15 and flows into the control unit 8 using the inside of the grip 3 as a passage. As a result, the control unit 8 would operate abnormally, causing problems in reliability and safety, such as inability to control the supply of electricity to the heater.

OBJECTS OF THE INVENTION The present invention solves these conventional problems and provides an iron with improved safety and reliability.

Structure of the Invention The iron of the present invention includes a base heated by a heater, a handle provided on the base, a water tank detachably provided at the front of the handle and having a water inlet. The water tank is equipped with a lock button for holding the water tank attached, and a control section located behind the water inlet and provided inside the handle. It is attached from the front side of the water inlet, and a water-blocking wall is formed on the handle between the control part and the water inlet.

According to the above configuration, even if water overflows from the water inlet and gets caught in the handle, the wall provided behind the water inlet prevents the water from entering the control unit, and the normal operation of the control unit can be maintained. This improves safety and reliability.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below based on the accompanying drawings. In FIG. 1, a temperature sensor 23 is mounted on a base 21 containing a heater 22. As shown in FIG. Further, a handle 25 is provided on the upper part of the base 21 and is composed of a grip part 26 and a heat insulating part 27, and has an opening part 28 at the rear part. This opening 28 includes a control section 24 covered with an outer shell member 29.
are tightened with screws, etc. This control section 24 receives a signal from the temperature sensor 23 and controls the supply of electricity to the heater 22. A water tank 30 is attached to the front of the handle 25, and a water inlet 31 is attached to the front of this water tank 30. The water tank 30 can be attached to and detached from the iron body by a lock mechanism operated by a lock button 32 attached to the front of the grip 26. The lower part of the lock button 32 is fastened with a screw 34 to a recess 33 formed in the front part of the grip part 26, and the end face of this recess 33 is formed with a watertight wall 35 to prevent water from entering the inside of the grip part 26. Prevents infiltration. Further, the lock button 32 is urged toward the water tank 30 by an elastic member 36.

To explain the operation in the above configuration, when using steam for ironing, it is necessary to place the iron in a freestanding state and pour water into the water tank 30. At this time, water overflowing from the water inlet 31 is applied to the handle 25, and the concave part 33 of the grip part 26 is leaked from the gap between the lock button 32 and the grip part 26.
Water enters the area. However, since the end face of the recess 33 formed in the grip part 26 to which the lock button 32 is attached forms the wall 35, water cannot penetrate into the inside of the grip part 26. Therefore, the control section 24 located below the grip section 26 will not be flooded with water.
4 can be maintained normally and reliability and safety can be improved.

Furthermore, by forming the wall 35 that blocks water from entering at the end face of the mounting recess 33 of the lock button 32, it is easier to make the thickness of the handle uniform during molding, thereby eliminating irregularities in appearance caused by variations in wall thickness. It has the effect that it can be removed and the appearance is improved.

Effects of the Invention As is clear from the description of the above embodiments, the iron of the present invention has a lock button for holding the water tank located at the front of the handle, and this lock button is attached from the front side of the handle to connect with the control section. By forming a water-blocking wall on the handle between the water inlet and the water inlet, it is possible to reliably prevent water that overflows from the water tank during water injection from entering the inside of the handle. Therefore, the control unit provided inside the handle is not adversely affected by water that has entered the handle, and malfunctions can be prevented and safety and reliability can be enhanced.

Furthermore, the lock button for holding the tank can also be placed at the front of the handle, which has excellent operability, without sacrificing usability.
