Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an iron provided with a humidifying device for stretching wrinkles of clothes or the like.

[0002]

Heretofore, such an iron having both a steam function and a mist function has been disclosed, for example, in Japanese Utility Model Publication No. 43-14792. Hereinafter, the configuration will be described with reference to FIG. 12. The base 201 forming the hanging surface is heated by a heater 202 as a heating unit, and the temperature is controlled by a thermostat (not shown) provided on the base 201. Reference numeral 203 denotes a vaporization chamber formed in the base 201, which forms a concave portion 204 at the bottom and
It communicates with the jet port 205 provided at the bottom of 01.

Reference numeral 206 denotes a vaporization chamber cover that covers the vaporization chamber 203 and is fixed to the upper surface side of the base 201. A water tank 207 for storing water is installed above the vaporization chamber 203, and thus above the vaporization chamber lid 206. Reference numeral 208 denotes a vertically movable valve rod which is inserted through the inside of the water tank 207, and opens and closes a nozzle 209 for dropping water from the water tank 207 to the vaporization chamber 203 by the valve rod 208. The guide tube 210 has a plug body 211 at the lower end thereof in a vaporization chamber.
The hole 212 provided at the bottom of the plug 211 is closed by a valve 213 so as to be vertically movable so as to be positioned on the recess 204 of the 203, and the upper end thereof is communicated with the mist nozzle 214. Reference numeral 215 denotes a water pipe provided along the guide pipe 210 in the water tank 207, and the upper end thereof communicates with the miss nozzle 214. 216 is a steam button for operating the valve rod 208, 217 is a guide tube 210 and a mist nozzle 214
Is a mist button for moving up and down.

The operation of the above configuration will be described. When the valve rod 208 is pulled up by operating the steam button 216, the nozzle 209 is opened from the previously closed state, and the water tank 2 is opened.
The water stored in 07 is dropped into the vaporization chamber 203. The vaporization chamber 203 is heated by the heater 202 together with the base 201, and the vaporization chamber 203 is heated.
The water dropped on the base 201 becomes steam and is spouted from a spout 205 provided at the bottom of the base 201, so that the clothes (not shown) can be steamed and ironed.

Next, when spraying a so-called mist from the mist nozzle 214, the mist button 217 is pushed while the valve rod 208 is pulled up by the steam button 216. Then, the guide pipe 210 is pushed down together with the mist nozzle 214 and the water pipe 215, and the plug 211 at the lower end of the guide pipe 210 seals the upper part of the concave portion 204 at the bottom of the vaporization chamber 203. When the water sealed in the recess 204 is heated and the vapor pressure is increased, the valve 213 which has been closed is opened, and steam is blown out from the mist nozzle 214 through the water pipe 210. With the ejection of the steam, the water in the water tank 207 is sucked through the water pipe 215, and the mist can be sprayed from the mist nozzle 214.

[0006] However, in the iron having the above configuration, the vaporizing chamber
Since 203 is formed integrally with the base 201, the base
When the temperature of 201 is set to a low temperature, or when the ironing operation is continuously performed, the temperature of the vaporization chamber 203 becomes low. In this case, even when water is supplied from the water tank 207 to the vaporization chamber 203, sufficient steam is not generated in the injection hole 205, and thus, it is not possible to obtain a sufficient vapor pressure to generate mist in the concave portion 204. , Which hindered the ironing work.

An object of the present invention is to provide an iron capable of sufficiently generating mist even when the temperature of the base is lowered or the set temperature of the base is lowered. For that purpose.

[0008]

When the water in the water tank is supplied to the vaporizer and vaporized by the iron according to the first aspect of the present invention, the steam generated in the vaporizer is guided from the steam passage to the mist nozzle section. Then, the water in the water tank is guided to the mist nozzle portion from the second water conduit by using the flow velocity of the steam injected from the mist nozzle portion, and is sprayed as mist from here onto the fabric.

In this case, the temperature of the base forming the hanging surface and the temperature of the vaporizer for vaporizing the water in the water tank are controlled independently by respective heating means. Therefore, even when the heat of the base is deprived of the fabric by the ironing operation and the temperature of the base is lowered or the set temperature of the base is lowered, the vaporizer maintains the preset temperature separately from the base. Therefore, a steam pressure required for mist generation can be obtained, and sufficient mist can be generated from the mist nozzle portion.

With the iron according to the second aspect of the present invention, the base and the carburetor, each of which is independently temperature-controlled, can be set at a set temperature without being significantly influenced by the temperature of the space interposed therebetween. Can be maintained.

According to the iron of the third aspect of the present invention, the water tank and the second water tank can be independently provided, and the water tank can be provided detachably. In addition, since no steam pressure is applied to the water tank, the water tank can be made of a material such as plastic, so that the material can be freely selected without considering the steam pressure.

According to the iron of the fourth aspect of the present invention, by providing a check valve, it is possible to prevent steam from flowing from the vaporizer to the water tank, so that it is possible to eliminate adverse effects when steam enters the water tank. .

LED 88 corresponding to "OFF" of operation panel 84 by 111
Lights up. In this off state, the first
Is not energized. Then, step S
When the setting button 85 is pushed and operated in 2, the setting mode is switched from “off” to “low”, “medium”, and “high” in this order, and the corresponding LED 86 is turned on. And step S
When the mode is switched to the setting mode of the temperature setting means 109 other than “OFF” at 3, the first heater 2 is energized by the first temperature control device 39.

The first temperature control device 39 performs the following step S
In 4, the iron placement detecting means 108 detects whether the iron main body 1 is being placed or removed. In a state where the iron body 1 is continuously mounted on the mounting table 101, the first heater 2 heats the base 3 until the temperature of the base 3 reaches the temperature set by the temperature setting means 59. At this time, the first temperature control device 39
Is within the appropriate temperature range close to the set temperature, based on the detection output from the temperature detection means 107 (step S
5). When the temperature of the base 3 is out of the appropriate temperature range, the process proceeds to the next step S6, where the LED 86 of the temperature display section 87 corresponding to the set temperature is made to blink, and the buzzer is sounded.
The user is notified that the base 3 is in an unsuitable temperature state without performing the notification by 89. On the other hand, when the temperature of the base 3 is within the appropriate temperature range in step S5, the process proceeds to step S7, where the LED 86 of the temperature display section 87 corresponding to the set temperature is turned on, and the buzzer 89 sounds for a predetermined time. Then, the user is notified that ironing is possible. Then, the first temperature control device 39
As long as the iron body 1 is mounted on the mounting table 101, so that the temperature of the base 3 is maintained within an appropriate temperature range,
The first heater 2 is controlled to be turned off, and the process returns to step S4 irrespective of whether the temperature of the base 3 is appropriate or inappropriate.

Thereafter, in step S4, when the iron main body 1 is detached from the mounting table 101 for ironing, the power supply from the mounting table 101 to the iron main body 1 is cut off, and the first heater 2 is turned off. Becomes The first temperature control device 39 continues to operate by power supply from the power storage device 90, but in the next step S8, when the temperature of the base 3 falls below the appropriate temperature range, or by operating the setting button 85. When the set temperature in the temperature setting means 109 is switched to a higher temperature than before, the buzzer 89 or the LED 86 is used to set the mounting table 10 of the iron body 1.
Notification or display of power supply for prompting placement on 1 is performed. Then, the process returns to step S4.

When ironing, after inserting a hand through the cavity 83 of the iron body 1, the handle 81 of the handle 7 is inserted.
And hold it in your palm. At this time, the abdomen 82 of the iron body 1 below the handle 81 is located at a position lower than both sides of the first water tank 8 provided along both sides of the iron body 1, and the handle 81 and the abdomen 82 A wide cavity 83 is secured between the handle and the handle 81, so that the back of the hand, that is, the back of the hand, does not easily hit the abdomen 82 of the iron body 1 so that the handle 7 can be easily held. Become. In addition, in order to make the leading end portion of the base 3 easily visible, the front end surface of the first water tank 8 is inclined so as to relatively largely fall toward the rear side of the iron main body 1. Since both sides of the first water tank 8 in the example are secured high enough to accommodate a sufficient amount of water, it is possible to eliminate the shortage of capacity of the conventional water tank.

As described above, when the base 3 is set to a desired temperature by operating the setting button 85, the first temperature controller 39 turns on the power to the first heater 2 based on the output signal of the thermistor 38. Control to maintain the base 3 at the set temperature. When the setting button 85 is set to a value other than "OFF", the second temperature control device 40 controls the energization of the second heater 22, and sets the vaporizer 21 to a preset temperature (about 180 to 240 ° C). To maintain. Thus, the temperature of the base 3 and the vaporizer 21 are independently controlled by the separate temperature controllers 39 and 40, respectively. On the other hand, the iron body 1 as shown in FIG.
In a state where the iron body 1 is placed on the iron body 1, the iron body 1 is held in a state of being inclined backward by about 20 °. In this state,
As shown in FIG. 7, a rolling surface 28 inside the check valve 23 is provided.
Is lowered by about 10 ° toward the connection port 31 side, and the ball 29 moves to the connection port 31 side to open the valve element 32. Therefore, the first
The water in the water tank 8 passes through the first water conduit 19 from the water flow joint 16 and flows into the second water tank 20. However, when the iron body 1 is placed on the mounting table 101, the rear end of the operating body 44 protruding from the rear cover 95 is pressed into contact with the receiving portion 103 of the mounting table 101, and Since the inclined surface formed on the front side contacts the head of the steam opening / closing rod 42 and moves the steam opening / closing rod 42 in a direction to close the nozzle 36,
Water does not flow into the vaporization chamber 37. By moving the steam opening / closing rod 42 in a direction in which the operating body 44 in contact with the mounting table 101 closes the nozzle 36, when the iron main body 1 without ironing is mounted, useless steam is generated by the vaporization chamber 37. Can be prevented.

Next, in order to perform ironing, when the iron main body 1 is lifted from the mounting table 101, the operation body 4 is lifted.
Since the rear end of 4 is separated from the receiving portion 103 of the mounting table 101, the operating body 44 moves backward by the urging force of the spring 45, and the contact state between the operating body 44 and the steam opening / closing rod 42 is released. In this state, operate the steam button 47 to the steam side,
When the manual operation body 46 is moved upward, the contact state between the manual operation body 46 and the steam opening / closing bar 42 is also released, and the steam opening / closing bar 42 is pushed up in a direction to open the nozzle 36 by the elastic force of the spring 43. When this happens, the water stored in the second water tank 20 until then passes through the nozzle 36 and evaporates into the vaporization chamber 37.
And heated by the vaporizer 21 maintained at a preset temperature, and rapidly becomes steam. This vaporization chamber 37
Steam generated in the steam feedback tube 48
Through the opening 49 and stored in the second water tank 20. The opening 49 formed in the steam feedback tube 48 is
The steam is provided at a position higher than the liquid level of the second water tank 20 when the nozzle 36 is opened, and the steam returned to the second water tank 20 is directly sent to the water stored therein to form a foam. Is prevented. The steam button
When the manual operation body 46 is moved downward by operating the 47 on the dry side, the manual operation body 46 comes into contact with the head of the steam opening / closing rod 42, and the steam opening / closing rod 42 Is moved downward, so that water does not flow into the vaporization chamber 37. Therefore, in this case, steam is not generated from the vaporization chamber 37 regardless of whether the iron main body 1 is mounted on the mounting table 101 or not.

When the iron main body 1 is lifted from the mounting table 101 and the steam button 47 is operated to the steam side, when the iron main body 1 is brought into a substantially horizontal state (ironing state), as shown in FIG. The rolling surface 28 inside the check valve 23 is lowered by about 10 ° toward the connection port 30 side, and the ball 29 moves to the connection port 30 side and the valve body 32
In close contact. When this happens, the valve body 32 closes and shuts off the flow between the water-flow coupling 16 and the second water tank 20, so that
The steam discharged from the vaporization chamber 37 to the second water tank 20 does not flow backward from the first water conduit 19 to the water-flow joint 16 side.

The steam stored in the second water tank 20 passes through the steam passage 50 and gushes into the mist chamber 51 in the mist guide 52 from the steam ejection nozzle 56 of the mist nozzle 53. Along with this, the mist ejection nozzle 58
Of the first water tank 8 is sucked from the water flow joint 16 through the second water passage 57 and crushed into fine mist at the mist jet nozzle 58. . The mist ejected from the mist ejection nozzle 58 is sent out through the mist chamber 51 toward the opening 54 along the flow of steam from the steam ejection nozzle 56, and the mist of the base back plate 5 attached to the base 3 is removed. It is sprayed onto the fabric from the spout 55. By performing ironing in this state, it is possible to give sufficient moisture to the fabric facing the lower surface of the base 3 and the base back plate 5,
As a result, a good finished state can be obtained.

Even when the heat of the base 3 is deprived of the fabric by the ironing operation and the temperature of the base 3 is lowered, or when the temperature of the base 3 is set to a low temperature (for example, about 110 ° C.) such as synthetic fiber, The vaporizer 21 is provided with a second heater 22 separately from the base 3 and is independently temperature-controlled, so that a temperature sufficient to obtain a steam pressure required for mist generation can be maintained and stable. The mist can be sprayed from the mist outlet 55 onto the fabric. Further, since the base 3 and the vaporizer 21 are separate members, and a space 35 for thermal insulation is provided between them, the temperature of the base 3 and the vaporizer 21 which are individually controlled independently is controlled. Can be maintained at the set temperatures without being significantly affected by each other.

The amount of mist injected from the mist outlet 55 is
It can be adjusted by operating the operation button 62. Specifically, as shown in FIG. 9, when the operation button 62 is pushed down to its operation lower end position, the operation button 62 and the rotor 63 are both locked by the rotor 63 below the operation button 62,
The joint 64 and the valve body 61 are also held at the pushed-in positions against the biases of the springs 68 to 70. Then, the steam stored in the second water tank 20 passes through a small gap between the outer surface of the valve body 61 and the inner surface of the steam passage 50, and a small amount of steam is supplied from the steam ejection nozzle 56 to the mist chamber 51. Is injected. Therefore, in this case, the amount of water sucked from the first water tank 8 to the mist ejection nozzle 58 also decreases, and a small amount of mist is ejected from the mist ejection port 55 to the fabric.

On the other hand, when the operation button 62 is further pushed down from this state, the locked state of the rotor 63 is released, and the urging force of each of the springs 68 to 70 causes the valve body 61 and, consequently, the operation button 6 to rotate.
2. The rotor 63 and the joint 64 are pushed up and return to the position shown in FIG. At this time, since the valve element 61 opens the steam passage 50, a large amount of steam is injected from the steam jet nozzle 56 into the mist chamber 51. Therefore, in this case, the first
The amount of water sucked from the water tank 8 to the mist jet nozzle 58 also increases, and a large amount of mist is jetted from the mist jet port 55 to the fabric. By simply operating the operation button 62, the amount of mist injected from the mist outlet 55 can be easily controlled.
It can provide a convenient iron.

When a part of the mist generated from the mist ejection nozzle 58 touches a part of the inner wall surface of the mist guide 52, the mist is cooled by this part to form dew. The water droplets flow down along, and are discharged from the opening 54 through the mist outlet 55, and may cause the fabric to stain. However, in the present embodiment, when dew condensation water adheres to the inner wall surface of the mist guide 52 and flows down along the inner wall surface of the mist guide 52, a gap 72 formed between the mist guide 52 and the water recovery receiving portion 71 is formed. The water enters the water collecting surface 71 of the water collecting and receiving portion 71 on which the hydrophilic paint is applied, and diffuses.

As described above, the dew water adhering to the inner wall surface of the mist guide 52 is received by the water recovery receiving portion 71 provided over the front periphery of the opening 54 of the base 3, so that the opening 54
No dew water is discharged from the mist outlet 55 through the mist outlet 55. Further, the dew water that has reached the gap 72 does not stop there, but is quickly diffused by the hydrophilic action of the water receiving surface 76 and is steamed by the heated base 3. At this time, even if the collected dew condensation water boils due to the heat of the base 3, the water collection receiving section
Since the projections 71 are formed so as not to overflow the dew condensation water, there is no danger that the projections 71 will get over the water recovery receiving portion 71 and scatter from the opening 54 to the mist outlet 55 and eventually to the fabric. The condensed water diffused to the water receiving surface 76 is timely discharged from a steam discharge port 73 provided in the base back plate 5 through a steam hole 74 while being steamed by the heat of the base 3. Since the steam hole 74 is provided to face the fabric to be ironed, there is an advantage that the dew water adhering to the mist guide 52 can be effectively sprayed as steam on the fabric. The condensed water thus collected can be discharged to the outside of the iron main body 1 through the steam hole 74 without staying inside the iron main body 1, and the opening 54 serving as a mist outlet is formed on the base surface of the iron main body 1. , The workability of ironing can be improved.

A steam passage 50 for guiding steam generated by the vaporizer 21 to the mist nozzle portion 53; a first heater 2 and a second heater 22 as heating means provided in the base 3 and the vaporizer 21; And the second heater 22,
A first temperature control device 39 and a second temperature control device as temperature control means for controlling the temperature of the base 3 and the vaporizer 21 independently.
40 and is equipped.

With such a configuration, the first water tank 8
When the water is supplied to the vaporizer 21 and vaporized, the steam generated in the vaporizer 21 is guided from the steam passage 50 to the mist nozzle unit 53. The water in the first water tank 8 is guided from the second water conduit 57 to the mist nozzle portion 53 by utilizing the flow velocity of the steam injected from the mist nozzle portion 53, and is sprayed as mist from the water on the fabric. In this case, the base 3 forming the hanging surface and the vaporizer 21 for vaporizing the water in the first water tank 8 are provided.
Are independently and independently temperature-controlled by the first heater 2 and the second heater 22. Therefore, even when the temperature of the base 3 is lowered by the heat of the base 3 being taken off by the fabric by the ironing work, or the set temperature of the base 3 is lowered,
Since the vaporizer 21 maintains a preset temperature separately from the base 3, it is possible to obtain a steam pressure necessary for generating mist, and it is possible to generate sufficient mist from the mist nozzle 53. .

In such a configuration, a heat insulating space 35 is provided between the base 3 and the vaporizer 21 in this embodiment. As a result, the base 3 and the vaporizer 21 that are individually temperature-controlled independently can be maintained at the set temperatures without being significantly affected by the temperature of the space 35 interposed therebetween. In this embodiment, since the base 3 and the carburetor 21 are respectively composed of different members,
Both are less likely to be affected by temperature.

In the present embodiment, the first water tank 8 and the second water tank 20 are provided separately, but the second water tank 20 is omitted to simplify the structure, and the first water tank 8 and the second water tank 20 are omitted. The function of the second water tank 20 may be combined with the water tank 8. However, as in the present embodiment, the water in the first water tank 8 is temporarily stored between the first water conduit 19 and the vaporizer 21, and the steam generated in the vaporizer 21 is temporarily stored. If it comprises so that the 2nd water tank 20 may be provided, the 1st water tank 8 and the 2nd water tank 20 can be independently provided in the iron main body 1, and the 1st water tank 8 1 can be provided detachably. Further, since steam pressure is not applied to the first water tank 8, the material of the first water tank 8 can be formed of a material such as plastic.
Free material selection is possible without considering the steam pressure.

Further, in the present embodiment, the first water tank 8 is provided between the first water tank 8 and the second water tank 20.
A non-return valve, that is, a check valve 23 for blocking the flow of steam to the water tank 8 is provided. In this case, by providing the check valve 23, the inflow of steam from the vaporizer 21 to the first water tank 8 can be prevented, so that the adverse effect when steam enters the first water tank 8 can be eliminated. . In particular, in this embodiment, the valve body 32 of the check valve 23 is opened when the iron body 1 is mounted on the mounting table 101, and the valve body 32 of the check valve 23 is closed when the iron body 1 is in a horizontal state. The movable body, ie, the ball 29, is provided so as to be able to roll on the rolling surface 28, so that in the horizontal state of the iron body 1 when ironing is performed, the check valve 23 is connected to the first water tank 8 and the second water tank 8.
The flow between the first water tank 8 and the water tank 20 can be blocked, and the flow of steam into the first water tank 8 can be reliably prevented with a simple structure.

Note that the present invention is not limited to the above-described embodiment, and various modifications can be made. For example, in the present embodiment, the mist outlet 55 is provided on the base back plate 5, but may be provided on the base 3.
