Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to, for example, an iron that sprays a suitable amount of steam from the underside of a base.

[Technical background of the invention and its problems]

This type of 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 eject steam.The water tank has a water inlet, and this inlet By supplying water into the water tank through the water spout, it is also possible to discard unnecessary water inside the iron after use.

The water inlet is equipped with a temporary lid for opening and closing, but the conventional cover plate is of a rotating type that rotates around one edge of the lid, so when filling water, it is necessary to open the water inlet. When doing so, place the lid plate on the front side of the water tank! Therefore, the lid plate should be raised in front of the water tank.
However, the problem with NII is that the pouring water especially gets in the way of water pouring work, and there is a risk that the cover plate may come into contact with other objects and be damaged or deformed.

The valve body 55 is raised by the elastic force of 7, and the opening 13 is opened.

A locking body 65 is provided at the upper front end of the handle 6 so as to be slidable along the front-rear direction of the handle 6. This locking body 65 has an annular base 66 in the middle part, and this base 6
A locking piece 67 and an operating knob 68 are integrally provided on one end side and the other end side, respectively. And this locking body 65
is elastically biased toward the front IQ of the handle 6 by a spring 69, the operating body 36 is loosely disposed inside the annular base 66, and the locking piece 67 is projected to the front of the handle 6, An operating knob 68 is projected upward from the top surface of the handle 6. A projecting piece 70 projects almost horizontally from the upper part of the back surface of the water tank 2, and this projecting piece 7o comes into pressure contact with the lower surface of the locking piece 67 based on the elastic force of the spring 22 in the valve mechanism 18, thereby causing the iron body The water tank 2 is maintained relative to the water tank 1.

A water injection lower 2 is formed at the upper part of the front side of the water tank 2, and the entire outer surface of the front side is covered with a window frame 73. A water injection window 74 is formed substantially at the upper part of the window frame 73 and is opposed to the water injection lower 2, and a cover plate 75 is attached to the inner surface of the window frame 73 so as to be slidable up and down. A knob 76 integrally projects from the upper edge of the cover plate 75, and this knob 76 faces the front side of the window frame 73 through the water inlet window 74. In addition, recesses 77.7B are formed in the back 1n1 of the lid plate 75 at the upper and lower ends, respectively, and a plate 79 is provided in the middle of the front side of the water tank 2. 1 and 6, the leaf spring 7
9 elastically fits into a recess 78 on the lower end side of the cover plate 75, thereby holding the cover plate 75 on the upper side of the window frame 73 and closing the water injection window 74.

Next, the effect will be explained. When the operating body 36 is rotated via the operating knob 32 and the operating knob 37 is aligned with the "STEAM" position on the display plate 34, the heater 7 is energized. Further, as the operating body 36 rotates, the cam *35 also rotates integrally, and the cam surface 38 rotates accordingly.
Due to the height difference of 39°, the interlocking rod 41 and the adjusting rod 44 are displaced upward [FIG. 7(a)]. The adjustment rod 44 is used to set the temperature controller. The interlocking rod 41 rises as described above, but the opening and closing rod 31
0, so the opening/closing rod 31 does not rise and the nozzle hole 32 remains closed.

As the heater 7 is energized, the temperature of the base 3 gradually rises, and when the temperature reaches a temperature sufficient to generate steam, the bimetal 48 senses this and reverses itself. Due to this reversal of the bimetal 48, the C response rod 49 and the regulation plate 50 rise together against the spring 54, and the regulation 8!
The restriction of the opening/closing rod 31 by the opening/closing rod 50 is released by m-, and as a result of this release, the opening/closing rod 31 is raised by the biasing force of the spring 53, and the nozzle hole 32 is opened (FIG. 7(b)).

By opening the nozzle hole 32, the water introduced into the water conductor 12 through the outlet 17 of the water tank 2 is sequentially dripped into the evaporation chamber 8. Then, this water evaporates due to the heat of the base 3 and becomes steam, and this steam flows from the valve case 14 to the opening 1.
3 into the branch chamber 9 and directly into the guide chamber 10, and further discharges from these compartments 9, 10 to the lower surface side of the base 3 through the jet holes 15, 16, respectively. Here, if the operation button 60 is pressed and the opening 13 is closed via the valve body 55, the steam is stopped from being ejected from the ejection hole 15 of the diversion chamber 9, and the ejection hole 16 of the guide 'yl 10 is stopped.
Steam is concentrated and ejected only from the inside.

If you remove the operation knob 37 from the "steam" display position and bring it to the "medium temperature" display position, the cam surface 38.39
When pressed, the interlocking rod 41 and the adjusting rod 44 are respectively displaced downward. Then, by lowering the adjustment rod 44, the ``temperature 1 regulator'' is operated to maintain the temperature of the base 3 at ``medium temperature''.

Further, as the interlocking rod 41 descends, the opening/closing rod 31 is pressed against the spring 53, and the nozzle hole 32 is closed, thereby stopping the output of steam [Fig. 7(C)].
. Base 3 by switching the set temperature by adjusting the crystallinity.
When the temperature of the spring 54 falls below the temperature when steam is generated, the bimetal 48 reverses, and the response rod 49 and the regulating plate 50 move downward by the force of the spring 54 (I'
The opening/closing rod 31 is restrained by the IJ plate 50, and the nozzle hole 32
The closed state is reliably maintained. Such an operation is performed using the operation knob 37 and the display plate 34.

The same applies when the display position is set to "low temperature". Also, while the operation error 37 is aligned with the display position of "STEAM" on the display plate 340, for example, disconnect the plug of the source cord from the outlet to cut off the communication to the heater 7. In this case, the bimetal 48 reverses as the base 3 decreases, and the opening/closing rod 31 is forcibly pressed by the regulating plate 50 against the spring 53, regardless of the position of the operating knob 37. The nozzle hole 32 is closed and the ejection of steam stops.

As described above, unless the base 3 is maintained at a temperature suitable for generating steam, the nozzle hole 32 is always forcibly closed, and therefore water does not accumulate in the evaporation chamber 8 inadvertently.

To replenish water in the water tank 2, the water tank 2 must be removed from the iron body.
11M, first, hook the fingertip on the operation knob 68 of the locking body 65 and release the locking body 65 into the spring 6.
9, slide the nozzle to the rear side of the nozzle 6. This operation causes the locking piece 67 to detach from the protruding piece 70 of the water tank 2, and the elastic force of the spring 22 of the valve mechanism 18 causes the entire water tank 2 to float up in a hop-like manner. It can be easily removed from the iron body 1. In addition, when the water tank 2 floats up, the valve body 21 is inserted into the side where the outlet 17 is disposed by the elastic force of the spring 22, and the outlet 17 is closed by the valve body 21, so that water is discharged from the water tank 2. There is no leakage.

After removing the water tank 2 from the iron body 1, hook the handle 76 of the lid plate 75 with your fingertips, pull the lid plate 75 downward, open the water filling window 74, and pour the water from the water filling window 74 into the lower water filling window. Water is replenished into the water tank 2 through 2. Temple board 7
5, the plate spring 79 separates from the recess 78 at the lower end of the cover plate 75 and fits into the recess 77 at the upper end, so that the lowering position of the cover plate 75 is reliably determined, and water is poured. The open state of the window 74 is stabilized. Furthermore, when discharging unnecessary water remaining in the water tank 2 after using the iron, the water filling window 74 is opened in the same manner. After the water filling work is completed, the lid plate 75 is pulled upward to close the water filling window 74. In this case, the leaf spring 29 fits into the recess 71N on the lower end side of the cover plate 75, so that the sound board 75 will not be inadvertently lowered due to heartbeats, value bases, etc. The occlusion state becomes stable. Further, the cover plate 75 is always elastically pressed against the inner surface of the window frame 73 by the plate spring 79, so that the water filling window 74 is reliably closed, and therefore the water in the water tank 2 is kept flowing through the water filling window 73.
Use 4 as 1 city and don't use it: There is nothing that will make you successful. When sliding the cover plate 75 down -E, the knob 76 can be removed to easily and smoothly perform the operation.

The cover plate 75 is not of the rotating 5-assist type a) like the conventional one,
It slides along the inner surface of the window frame 73, so the cover plate 75 does not protrude to the front side of the water tank 2, and this prevents the attached body 75 from interfering with pouring and draining work. You can always perform the task easily and efficiently without any problems. In addition, the attached body 75 is always surrounded and protected by the peripheral wall of the window frame 73, so that objects 4ti2 do not come into contact with this lid body 75, and therefore the body 75 is protected. 75 break/praise and transformation 4jt
This can be highly prevented.

[Effect of the invention J As explained above, according to the present invention, the cover plate of the water tank does not interfere with the pouring and draining work, so the work can be easily and smoothly carried out, and the signboard can be displayed easily. This eliminates the effect of always protecting the window frame to reliably prevent damage and deformation.
