Abstract

PURPOSE:To allow easily and smoothly operating an operating part constantly without jolting a water tank by providing the operating part which controls water supply from a water tank to an evaporation chamber and is located in the front part of an iron main body. CONSTITUTION:When a cam plate 33 is turned by a knob 36 of an operating part 35 and the knob 36 is set to an indicating position 'STEAM' that is provided on a setting guide plate 37, a soleplate 3 is controlled to a temperature suitable for steam generation by a temperature controller which is operated by a connecting rod 41. And, an open-close rod 29 is raised to open a drip nozzle 28. Thereby, the water in a water path 12 drips through the drip nozzle 28 into an evaporation chamber 8, and is evaporated into steam by the heat of the soleplate 3. The steam is led to distribution chambers 9, and spouted from steam vents 10 on the back face of the soleplate 3. When the knob 36 is set to 'DRY' on the setting guide plate 37, the open-close rod 29 is lowered to close the drip nozzle 28, so that the water stops dripping and then the steam ceases to spout.

Description

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

[Technical background of the invention and its problems]

This type of steam iron is equipped with a water tank, and the water stored in the water tank is dripped into the evaporation chamber of the base to form steam, and the steam is guided to the bottom side of the base and ejected. . In order to facilitate the work of filling and draining water into the water tank, as seen in Japanese Utility Model Publication No. 45-11593, the water tank is constructed separately from the iron body, and when the iron is used, the water tank is attached to the iron body. It is known that the iron is attached to the iron body, and the water tank can be removed from the iron body when pouring water into the water tank.

However, in the steam iron disclosed in Japanese Utility Model Publication No. 45-11593, an operating body for controlling the supply of water from the water tank to the evaporation chamber of the iron body is provided in the middle part of the handle and in the lower part thereof. Therefore, it is difficult to operate the operating body.

Therefore, as seen in Japanese Unexamined Patent Publication No. 56-1.12300, a water tank is detachably provided in the front part of the iron body, and a water tank is inserted into the evaporation chamber of the iron body from inside the water tank to the upper end of the water tank. There have been provided devices that incorporate an operating body for controlling the supply of water to the container.

If the operating body for controlling the supply of water into the evaporation chamber is provided at the upper end of the water tank in this way, the outer circumferential side of the upper part is wide open, compared to the one in the above-mentioned Utility Model Publication No. 11593/1983. This has the advantage of making it easier to operate.

However, when the operating body is attached to the water tank, the force applied when operating the operating body is applied to the water tank, causing the water tank to wobble and the engagement mechanism between the water tank and the iron body to become loose. It deteriorates early and its durability decreases, and the water tank also rattles and becomes unstable, making it difficult to operate the operating body. Furthermore, since the operating body is located in the water tank, the operating body is moved away from the handle of the iron main body, making it difficult to operate the operating body while holding the handle.

[Purpose of the invention]

The present invention has been made with attention to these points, and its purpose is to provide a steam iron in which the operating body can always be operated neatly and smoothly without rattling the water tank. Our goal is to provide the following.

An engaging pawl 19 is integrally protruded from the upper rear surface of the water tank 2, and this engaging pawl 19 is elastically and detachably engaged with an engaging portion 20 provided at the upper front surface of the handle 6. There is.

A water inlet 21 is formed at the upper front surface of the water tank 2, and water is injected into the water tank 2 through this inlet 21, and unnecessary water in the water tank 2 is discharged. Note that from both sides of the water tank 2, there are side wall portions 22 (second
(only one of which is shown in the figure) extends, and this side wall portion 22 overlaps with the side surface portion on the front end side of the handle 6.

The water guide body 12 is formed by attaching a backing plate 24 to the upper surface of a mallet-shaped water guide base 23.
A cylindrical connecting portion 25 integrally protrudes from one end of the connecting portion 4, and a connecting port 26 is formed in the end surface of the connecting portion 25. Further, a bottle-shaped open body 27 integrally projects from the inner bottom surface of the water guide base 23, and the tip of this open body 27 faces the center portion of the connection port 26. Then, the connection port 26 is liquid-tightly connected to the water inlet 13 of the water tank 2, and the tip of the opening body 27 comes into contact with the valve rod 16 of the valve mechanism 14, pushing up the valve body 17 against the spring 18. The water inlet 13 is held in an open state so that the water in the water tank 2 is introduced into the water conductor 12 through the water inlet 13.

A drip nozzle 28 is provided at the bottom of the other end of the water guiding base 23 , and the tip of the drip nozzle 28 penetrates through the lid 11 and faces into the evaporation chamber 8 of the base 3 . Reference numeral 29 denotes an opening/closing rod that is provided to be vertically movable, and the tip side of this opening/closing rod 29 passes through the backing plate 24 and faces the inside of the dripping nozzle 28, and its vertical movement opens and closes the nozzle hole 30 of the dripping nozzle 28. It is something.

A support plate 31 is provided at the upper front end of the handle 6, and a cam disk 33 is rotatably supported on the support plate 31 via a support shaft 32. The upper part of the second cam disc 33 is covered with a cap 34, and an operating body 35 extends from the cam disc 33, and a knob 36 at the tip thereof faces the front part of the upper end of the handle 6. A setting display plate 37 is attached to the upper surface of the cap 34 in correspondence with the knob 36. On the lower surface of the cam disc 33, first and second cam grooves 38 and 39 are formed in the shape of an arc centered on the support shaft 32. The upper end of the operating rod 29 is inserted into the first cam groove 38 and is brought into contact with the inner bottom surface of the cam groove 38 by the elastic force of the spring 40. 41 is an interlocking rod, and the lower end of this interlocking rod 41 controls the energization of the heater 7 and connects the base 3.
The upper end of the interlocking piece 42 is inserted into the second cam groove 39, and the elastic force of the interlocking piece 42 causes the inner bottom surface to are in contact. The first and second cam grooves 38 and 39 have a height difference in depth from one end to the other end, and as the cam disk 33 rotates, the height difference causes the opening/closing rod 2
9 and the interlocking rod 41 are designed to move up and down.

Next, the effect will be explained. When the cam disk 33 is rotated through the knob 36 of the operating body 35 and the knob 36 is aligned with the "steam" display position on the setting display plate 37, the temperature is adjusted through the interlocking rod 41. The temperature of the base 3 is adjusted by the regulator to a temperature suitable for generating steam, and the opening/closing rod 29 is raised to open the drip nozzle 28. As a result of this opening, the water in the water guide body 12 drips into the evaporation chamber 8 through the drip nozzle 28, and is vaporized by the heat of the base 3 to become steam, and this steam is transmitted to each guide chamber 9...
The water is ejected sequentially from the inside through each of the ejection holes 10 to the lower surface side of the base 3.

Furthermore, when the knob 36 is set to the "dry" position on the setting display plate 37, the opening/closing rod 29 descends and the drip nozzle 2
8 is closed, the dripping of water into the evaporation chamber 8 is stopped, and the ejection of steam is stopped.

On the other hand, when replenishing water in the water tank 2 or discarding unnecessary water in the water tank 2 after completing ironing work, the engaging claw 1 is used as shown in Fig. 2.
9 and the engaging portion 20 are disengaged, and the water tank 2 is removed from the iron main body 1. At this time, since the valve rod 16 and the opening body 27 come out of contact with each other due to the removal operation, the valve body 17 is lowered by the biasing force of the spring 18, and the water passage port 13 is closed. This operation is performed regardless of whether the knob 36 of the operating body 35 is in the "steam" or "dry" position. Therefore, when the water tank 2 is removed from the iron main body 1, the water inlet 13 is always reliably closed, and water will not inadvertently leak out from inside the water tank 2.

The operating body 35 for starting and stopping water dripping is not provided on the water tank 2 side as in the conventional case, but is provided on the iron body 1 side, so that the force used for the operation is reduced by the water droplet. This prevents the water tank 2 from rattling and causing early deterioration of the engagement mechanism consisting of the engagement claw 19 and the engagement portion 20. Since there is no wobbling, the operating body 35 can be operated easily and smoothly. Furthermore, since the operating body 35 is provided on the side of the iron main body 1, the operating body 35 is placed close to the grip 6a of the handle 6, so that the hand holding the grip 6a while using the iron, etc. It is possible to operate the operating body 35 with the thumb or the like, further improving usability.

In addition, in this embodiment, since the single operating body 35 can perform both the operation of dropping water and stopping it, and the operation of setting the temperature controller, the overall operation is simplified, and There is an advantage that economical efficiency can be improved due to the dual use of members.

FIG. 3 shows another embodiment of the present invention, in which a push-button operating body 35a is provided on the iron body.
The drip nozzle 28 is opened and closed via the opening/closing rod 29.

That is, when the operating body 35a is pushed downward from the illustrated state, the opening/closing rod 29 is lowered and the dripping nozzle 28 is closed, and this state is changed by the engagement between the operating body 35a and the iron main body 1. Retained.

Then, when the operating body 35a is pressed again, the above-mentioned engagement is released.
The operating body 35a protrudes upward from the iron main body 1 due to the urging force of the spring 43, and the opening/closing rod 29 is moved by the spring 43.
, and the drip nozzle 28 is opened.

The valve mechanism installed in the water tank can be used as long as the water tank's water inlet is always closed and is held open by the opening body on the iron body side when the water tank is attached to the iron body. The configuration is not limited to the example, and various modifications can be made.

〔Effect of the invention〕
