The holder 19 is hooked onto the substrate 4 by engagement. Cap 15 provided on main body 9 of water tank 8
A latching piece 32 having a latching claw 31 at the tip is integrally provided on the back surface of the holder.

The locking piece 32 is removably engaged with a stepped portion 33 formed on the inner peripheral portion of the handle portion 7 via the locking portion 31 . The water tank 8 is fixedly attached to the base 1 by the engagement between the hooking piece 32 and the stepped portion 33 and the engagement between the holder 19 and the stopper spring 28. Then, by releasing each of the above-mentioned engagements from this attached state, that is, by pulling out the holder 19 against the elastic force of the latching spring 28 and detaching the latching pawl 31 from the rigid part 33, the water tank 8 can be removed from the base 1. Water is injected into the main body 9 in this removed state. To explain the procedure, first change the posture of the main body 9 from the normal position with the water inlet body 10 facing forward as shown in FIG. As shown, the water inlet body 10 is placed in an upright position facing upward, and in this position, the water inlet lid 12 is opened and water is injected into the main body 9 from the water inlet 11. The side surface of the main body 9 is provided with a first display line 34 that faces vertically when the main body 9 is placed in the upright position, and a second display line 35 that also faces horizontally. There is.

Since the main body 9 is made of a transparent material, when water is injected into the main body 9, changes in the water level can be easily recognized from the outside. When the water level reaches the first display line 35, which has become horizontal due to the rearrangement of the main body 9, the injection is stopped. As a result, a specified amount of water is injected into the main body 9, and excessive injection is prevented. After injecting water into the main body 9 in this way, close the water filling lid 12, return the main body 9 to the normal position, push the holder 9 into the closing opening 26, and hook the latching grooves 27, 27. The main body 9 is attached to the base 1 again by engaging the retaining parts 29, 29 of the stop spring 28, and engaging the retaining claws 31 of the retaining pieces 32 with the stepped parts 33 of the handle body 5. In this state,
The water level in the main body 9 coincides with the horizontal second display line 35, and from then on, the amount of water reduction can be easily grasped from the outside by comparing it with the second display line 35. From the inner bottom wall surface of the main body 9, a first wave plate 36 with a wide width on the left and right and a thin tube-like tube body 37 extend and stand upright, respectively, and the upper end of one tube body 37 is attached to the top wall surface of the main body 9. This is supported by welding, etc.

The aforementioned second operating punch 13 is inserted into this tube body 37. Furthermore, as shown in FIG. 6, a second wave plate 38 is integrally formed on the outer circumferential surface of the tube body 37, which faces the first wave plate 36 at a distance. In this way, the tube body 37 is integrally formed to extend from the inner bottom wall surface of the main body 9.
Since the operation tube 13 is inserted inside the main body 9, the liquid tightness inside the main body 9 is ensured, and the pipe body 37 allows the main body 9 to be sealed.
can be reinforced. Also, during ironing work, the whole body is moved back and forth a lot, but since the first and second wave plates 36 and 38 are provided inside the main body 9, the fluctuation of the liquid level inside the main body 9 is suppressed. Therefore, the water will not inadvertently pass through the water inlet 11 and leak to the outside. On the other hand, a recessed step 39 is formed on the lower surface of the base 1, and a dispersion plate 40 is attached to the recessed step 39 via screws 41.
As shown in Fig. 7, groove-shaped dispersion holes 4 are formed between the inner circumference green

Further, a concentration hole 43 is bored in a part of the distal end side of the dispersion plate 40. An evaporation chamber 44 is formed on the upper surface of the base 1 located on the opposite side of the dispersion plate 40, and this evaporation chamber 44 is connected to the concentration hole 43 via a first guide path 45.
The dispersion hole 42 is fitted through the second guideway 46 . A drip port 47 is formed on the upper surface of the evaporation chamber 44, and a valve □49 that forms part of the passage cross section is provided in the middle of the second concession path 46 in parallel with the drip port 47. ing. A packing 50 integrally formed of an elastic material is stretched across the drip port 47 and the valve port 49. This packing 5 has a connecting port 51 formed in a portion facing the dripping port 47, and a valve membrane portion 52 formed in a portion facing the valve port 49, respectively. Springs 53 and 54 are interposed on the lower surfaces of the connection port 51 and the valve membrane portion 52, respectively, and these springs 53 and 54 elastically urge the connection port 61 and the valve membrane portion 52 upward, respectively. A holder 19 provided on the bottom of the water tank 8 penetrates the substrate 4 and covers the cover 3.
It passes through and faces the upper surface of the packing 50.

The tip of the drop nozzle 21 provided on the holder 9 presses against the connection port 51 against the spring 53 and aligns with the connection port 51, and this engagement causes the drop nozzle 21 to move to the drip port. 47 in a fluid-tight manner. Further, a push plate 25 provided in the second operation village 14 protruding from the holder 9 faces the valve waist portion 52. In addition, 55 is a temperature controller for adjusting the temperature of the base, and 56 is its operation dial.

In the steam iron configured in this way, the base 1 is heated by the heater 2.

When the first operation button 16 is pressed down to close the lower nozzle 21, no steam is ejected from either the dispersion hole 42 or the concentration hole 43. In this state, when the first operation lever 016 is operated to pull the first operation village 13 upward and open the through-hole nozzle 21, the water in the water tank 8 flows through each through-hole 18...
. . . flows into the evaporation chamber 44 through the inside of the packing 22, the passing nozzle 21, and the dripping port 47 in order.
Steam is generated at At this time, if the valve □49 is open, the steam in the evaporation chamber 44 is ejected from the concentration hole 43 and the dispersion hole 44 over a wide area through the first and second guide paths 45 and 46. In response, the second operating punch 14 is pushed down by operating the second operating button 17, and the push plate 2
When the valve membrane part 52 is pressed against its own elasticity and the elasticity of the spring 54 through the valve 5 and the valve □49 is closed, the second guide path 46 is cut off, so that the steam in the evaporation chamber 44 is is concentratedly ejected only from the concentration hole 43. In addition,
In the above embodiment, the water tank is fixed to the base by the engagement between the holder 19 and the locking spring 28, and the engagement between the locking piece 32 and the stepped portion 33, but the latter engagement is an auxiliary engagement. There is no problem in trying to fix it only by the former engagement.

As explained above, according to the present invention, retaining grooves are formed on the side surfaces of both ends of the holder provided at the bottom of the water tank, and the holder is exposed to the lower surface of the substrate through the opening □ formed in the substrate. Further, a locking spring is provided on the lower surface side of the substrate, a pair of locking portions facing each other are formed on the locking spring, and these locking portions are elastically engaged with the locking grooves, respectively, to secure the holder. Since the holder is hung on the board, the water tank can be installed easily and quickly by simply pushing the holder into the opening of the board against the elastic force of the spring. Similarly, the holder can be removed easily and quickly by simply pulling the holder out of the opening against the elastic force of the latching spring.
