Taiwan Patent No. I2266397 JP2003-199999A

  However, the above-described base assembly 1 has the following drawbacks.

  First, when ironing at a low temperature, the temperatures of the first heating element 13 and the second heating element 14 are lowered. As a result, a large amount of vapor in the iron condenses into a liquid, then leaks out of the iron and leaks into the ironing object.

Second, since a part of the base 12 is occupied by the casing 121, and the steam generating unit 11 is connected to the casing 121 on the same plane as the casing 121 and occupies the other part of the base 12, the first steam chamber is received. Space is limited.
As a result, the amount of liquid in the first vapor chamber 111 is limited, and the amount of liquid that is evaporated by the vapor generation unit 11 and becomes vapor may be limited.

  Third, the steam in the first steam chamber 111 needs to first pass through the second steam chamber 122 via the hole 123 and can then flow out of the base 12, so that the structure of the base assembly 1 is complicated. This ultimately results in high manufacturing costs.

Fourth, the steam in the first steam chamber 111 can flow out of the base 12 by first entering the second steam chamber 122 via the hole 123, so that the steam is easily accumulated at the front end of the base 12, It is easy to overflow from there.
Therefore, the first half of the base 12 has excessive steam, while the latter half has insufficient steam.

  The present invention has been made in view of the above-described problems, and an object thereof is to provide a base assembly that has a large steam receiving space and a simple structure, and can reduce the manufacturing cost as much as possible. It is.

To achieve the foregoing object, the present invention provides a base assembly for a steam iron that includes a base and a steam generator that overlaps the base and cooperates with the base to define a steam distribution flow path between the base and the base. It is a product.
The steam generator defines a steam chamber disposed over the steam distribution channel and in fluid communication with the steam distribution channel.

  According to the present invention, it is possible to provide a base assembly having a large steam receiving space and a simple structure and capable of reducing the manufacturing cost as much as possible.

With reference to FIG. 2 again, the steam iron 9 will be described. In addition to assembling the base assembly 2 of the present invention, the steam iron 9 further includes a housing 91 that defines a water storage portion, a handle portion 92 formed on the top of the housing 91, and a housing 91. And a drip control unit (not shown) provided.
The housing 91 has a first water supply port 911 and a second water supply port 912 provided at the bottom thereof.
The handle portion 92 is provided with an adjustment knob. By pressing the adjustment knob, water can flow out from the bottom of the casing 91 through the first water supply port 911 or the second water supply port 912 via the dropping control unit.

The assembly of the casing 91 and the base assembly 2 will be described with reference to FIGS.
When the casing 91 and the base assembly 2 are assembled, the first water inlet 911 is connected to the first water inlet 421, and the second water inlet 912 is connected to the second water inlet 422.
In the present embodiment, the first steam chamber 461 is used to generate steam for the steam iron 9 for normal iron use and for cleaning the inside of the first steam chamber 461 and the steam generator 4. used.
The second steam chamber section 462 is used for causing the steam iron 9 to eject steam.
When the steam iron 9 is switched to the normal iron use or cleaning mode, liquid water flows through the first water supply port 911, passes through the first water injection port 421, and then enters the first steam chamber 461. .
The water is evaporated by the second heating element 6 to become water vapor.
The steam passes through the third steam chamber 463 via the gap 441, flows through the two steam discharge ports 411, and flows down to the steam distribution channel 200.
Finally, the water vapor flows out from the base 3 via the vapor outlet hole 33.

When the steam iron 9 is switched to the steam ejection mode, a large amount of liquid water flows through the second water supply port 912, passes through the second water injection port 422, and then enters the second steam chamber 462.
The water is evaporated by the first heating element 5 into a large amount of water vapor.
The steam flows into the third steam chamber 463 via the two open ends 443, travels around the baffle plate 442, moves to the two steam discharge ports 411, and descends to the steam distribution channel 200. The above is best shown in FIG.
Finally, the steam flows out from the base 3 via the steam outlet hole 33.

  Furthermore, when the steam iron 9 is in the steam ejection mode, a large amount of water enters the second steam chamber section 462 and evaporates. Before flowing to the steam outlet 411, the baffle plate 442 must be turned. As a result, the water entering the second steam chamber 462 can be efficiently evaporated by lengthening the path of the steam.

Furthermore, by providing the baffle plate 442, water that is not completely evaporated can be blocked by the baffle plate 442 and collected in the water collecting groove portion 412. This ensures that water that has not evaporated does not enter the vapor distribution channel 200 via the vapor outlet 411.
In this way, water flows out of the base 3 and does not leak into the ironing object.

In addition, in the present embodiment, the temperature setting of the second heating element 6 is higher than that of the first heating element 5.
For example, the second heating element 6 can heat the steam chamber 46 at two temperature settings (140 ° C. and 190 ° C.). And the 1st heat generating body 5 can heat the base 3 by seven types of temperature setting (107 degreeC, 118 degreeC, 127 degreeC, 146 degreeC, 171 degreeC, 188 degreeC, 190 degreeC).
When the 1st heat generating body 5 is set to 127 degrees C or less, the 2nd heat generating body 6 is set to 140 degreeC. When the first heating element 5 is set to 146 ° C. or higher, the second heating element is set to 190 ° C.
Therefore, even when the base 3 is at the lowest temperature (107 ° C.), the temperature inside the steam chamber 46 remains 140 ° C., so that water entering the first steam chamber portion 461 from the first water inlet 421 can be obtained. It can be completely evaporated.
Therefore, during the ironing operation with the base 3 at a low temperature, the steam chamber 46 ensures that the water vapor is kept completely evaporated and does not condense and become water.

  From the above description of the first embodiment, the effects can be summarized as follows.

  First, since the steam generating unit 4 that generates steam is superimposed on the base 3 to be ironed, the steam generating unit 4 has a wide space for generating a large amount of steam.

Second, in order to interconnect the steam generating part 4 and the base 3, the first groove part 32 and the second groove part 45 cooperate with each other by inserting the protruding edge 451 into the recessed part 322. A path 200 can be defined. The steam in the steam generating unit 4 enters the steam distribution channel 200, is spread along the steam distribution channel 200, and flows out from the base 3 via the steam outlet hole 33.
Therefore, the base assembly 2 of the present invention not only has a simple structure, but also reduces the manufacturing cost.

Thirdly, the steam in the steam generating section 4 flows down to the two end portions of the U-shaped steam distribution channel 200 via the two steam discharge ports 411. After that, by moving forward along the vapor distribution flow path 200, it is supplied from the base 3 via the vapor outlet hole 33.
Therefore, the steam is supplied uniformly from each steam outlet hole 33 and is not concentrated on a specific place of the base 3.
