Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an iron for smoothing wrinkles on clothes and the like.

[0002]

2. Description of the Related Art Conventionally, this type of iron has been constructed as shown in FIGS. The configuration will be described below. As shown in the figure, the base 31 has a heater 32 embedded therein, and a thermistor 33 for detecting the temperature of the base 31 and a temperature fuse 34 for preventing overheat are respectively relatively thin sheet metal of about 0.5 to 1 mm. Made conductive member 35
The conductive member 35 is attached to the heater 32.
The horizontal part is fixed to a holding member 36 made of an electric insulator such as ceramics located between the two parts by a rivet 37 made of aluminum.

A conductive member 39 is attached to the holding member 36 at a position facing the terminal portion 38 of the heater 32. The heater 32 can be energized by fixing the holding member 36 to the base 31 with a screw and electrically connecting the conductive member 39 and the terminal portion 38 of the heater 32 by spot welding or the like. The conductive member 35 is the base 3
The heater 32 is energized by a signal from the thermistor 33 by penetrating a hole provided in the rear of the handle 40 that covers 1 and connecting to a control circuit (not shown) via a contact 42 provided in the connector 41. Then, the base 31 is controlled to a required temperature.

[0004]

However, in such a conventional structure, the holding member 36 made of an electric insulator such as ceramics, to which the conductive member 35 is fixed, is directly attached to the high temperature base 31. The heat of the base 31 is conducted to the conductive member 35 via the holding member 36,
Was raising the temperature. The conductive member 35 is joined to the contact 42 provided in the connector 41, but the temperature of the conductive member 35 rises, so that the connector 4
There is a problem that the temperature of the joint with the contact 42 in 1 also naturally rises and the joint loosens due to heat, and the joint strength becomes weak.

Further, the conductive member 35 is relatively thin 0.5.
It should be joined to the contact 42 in the connector 41 because it is formed of a sheet metal member of about 1 mm and the horizontal portion of the conductive member 35 is fixed to the holding member 36 using an aluminum rivet 37 or the like. There has been a problem that the vertical rising portion is easily deformed during transportation or assembly and is not securely joined.

Further, since the conductive member 35 is bitten and fixed to the holding member 36 by using the rivet 37 made of aluminum, there is a problem that the bite portion is loosened by heat, and
There is also a problem that the holding member 36 made of ceramic or the like is cracked by the pressure at the time of biting. As a matter of course, since the conductive members 35 are bitten one by one on the holding member 36 by using aluminum rivets 37, there is a problem that productivity is poor.

Further, the holding member 36 is directly attached to the high temperature base 3
Since it is necessary to use a heat-resistant material such as ceramics for attaching to No. 1, there is a problem that the workability is generally poor and the cost of parts is high.

Next, regarding the connection of the conductive member 35 and the connector 41, the contact 4 in the connector 41 is generally used.
2 is made of a spring material and is pressure-bonded to the conductive member 35. In particular, a large current flows through the conductive member 35 that supplies electricity to the heater 32. There was a problem that it was easy to loosen and could not reliably supply electricity.

In some cases, the connector 41 may not be completely joined to the conductive member 35 during the assembling work, so that the signal transmission of the thermistor 33 and the heater 3 may be impossible.
There was also a problem such as a failure in power supply to No. 2.

The present invention is to solve the above-mentioned problems, and it is a first object of the present invention to suppress the temperature rise of a conductive member and a connector joined to this conductive member to ensure mutual electrical connection.
The purpose is. The second purpose is to suppress the temperature rise of the conductive member and the connector joined to the conductive member, and improve the quality and the assemblability. The third purpose is to ensure the connection between the conductive member and the connector, and to eliminate the signal transmission failure of the thermistor and the failure of current supply to the heater.

A fourth object is to improve the quality and assemblability by preventing the vertical rising portion of the conductive member joined to the contact in the connector from being deformed during transportation or assembly. A fifth object is to improve the processing accuracy of the holding member and ensure that the conductive member can be held. A sixth object is to fix the conductive member to the holding member without using an aluminum rivet or the like, to stabilize the quality, and to improve the workability.

The support 12 and the cut-and-raised portion 15 are used to pass through and hold the support 12. Similarly, the holding member 9 is provided with a through hole 17 at a portion corresponding to the support portion 14 and the cut and raised portion 15 of the conductive member 13.
The conductive member 13 is held through the supporting portion 14 and the cut-and-raised portion 15 so as to pass therethrough.

The holding member 9 having the thermistor connecting member 8 and the conductive members 11, 12 and 13 penetratingly held in the above structure maintains a constant space distance (electrical insulation distance), and is held in a hollow position above the base 1. The conductive members 11 and 13 are connected and held to the terminal portions 10a and 10b of the heater 2 by spot welding or the like.

The thermistor connecting member 8 and the vertical portions of the conductive members 11 and 12 and the holding member 9 are the base 1 described above.
It is located behind the upper surface of the. As a matter of course, the thermistor connecting member 8 and the conductive members 11, 12 and 13 are not detached from the holding member 9 by the supporting portion 14 and the cut-and-raised portion 15.

The thermistor connecting member 8 and the conductive members 11 and 12 are connected to a control circuit (not shown) through a connector 18 through a hole provided at the rear of the handle 4 covering the base 1. . Therefore, the energization of the heater 2 is controlled by the signal of the thermistor 6, and the base 1 is controlled to a required temperature.

As described above, according to this embodiment, the heater 2
Conductive member 1 electrically connected to the terminals 10a and 10b of the
1, 12 and a holding member 9 holding the conductive member 13 and the thermistor connecting member 8 connected to the thermistor 6 maintain a constant space distance (electrical insulation distance) and are electrically conductive to a position where they are hollowly held above the base 1. Since the members 11 and 13 are connected and held to the terminal portions 10a and 10b of the heater 2 by spot welding or the like, the high-temperature heat of the base 1 is not directly transferred to the holding member 9, so that the holding member 9 is naturally heated. The temperature rise is suppressed, and the temperature rises of the thermistor connecting member 8 and the conductive members 11, 12 and 13 held therein are also suppressed. Further, the thermistor connecting member 8

Next, a second embodiment of the present invention will be described with reference to FIG. The same components as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted. Reference numeral 19 denotes a support member having one end fixed to the rear upper surface of the base 1 with a screw or the like, and the other end supports the cover 3 and is fixed with a screw or the like, and the holding member 9 is installed on the support member 19. Although it is locked with a screw or the like, the holding member 9 does not necessarily have to be locked with the support member 19.

There is no problem if the support member 19 is fixed to the base 1 at one end and the cover 3 is fixed to the other end, but the support member 19 is integrally fixed to the holding member 9 by screws or the like. When it is unitized, the assemblability can be improved, such as automatic setting is possible. This embodiment is effective when the cover 3 or the handle 4 cannot be directly fixed to the base 1 due to the heat resistant temperature of the material forming the cover 3 or the handle 4.

Next, a third embodiment of the present invention will be described with reference to FIG. This embodiment relates to the connection between the thermistor connecting member 8, the conductive members 11 and 12, and the connector 18. A contact 20 made of a spring material for transmitting a signal from the thermistor 6 and a terminal 21 for energizing the heater 2 are locked inside one connector 18 by a locking means such as a claw.

The terminal 21 is electrically connected to the conductive members 11 and 12 facing them by a wiring screw.

As described above, according to this embodiment, the connector 18 in which the contact 20 made of the spring material for transmitting the signal of the thermistor 6 and the terminal 21 for energizing the heater 2 are locked together is connected to the thermistor. When engaging the member 8 and the conductive members 11 and 12, the contact 20 is crimp-connected to the thermistor connecting member 8 facing them, and the terminal 21 is connected by the wiring screw to the conductive member 1 facing them.
Since the connector 18 is connected to the terminals 1 and 12, the terminal 21 cannot be screwed unless the connector 18 is surely set on the thermistor connecting member 8 and the conductive members 11 and 12. Further, since the terminal 21 is connected to the conductive members 11 and 12 by screwing, the connecting member and the conductive member do not loosen due to vibration or heat.

As is apparent from the above embodiments, according to the present invention, the base heated by the heater, the cover covering the upper surface side of the base, the cover arranged on the cover, and the hollow portion at the rear part. A handle having a terminal portion, and a conductive member having one end protruding in the terminal portion of the handle,
A holding member for aligning and holding the conductive member at a predetermined position, and fixing the other end of the conductive member to the terminal portion of the heater to make the holding member hollow at a predetermined distance from the base. Since it is held, the high temperature heat of the base is not directly transmitted to the holding member, so that the temperature rise of the holding member is suppressed and the temperature rise of the conductive member held therein is also suppressed. Furthermore, since the temperature rise of the connector connected to the conductive member (more precisely, the contact and terminal locked in the connector) is suppressed, the conventional joint part (especially crimping joint made of spring material) is not heated. By loosening, the joint strength becomes weaker, and problems such as poor signal transmission of the thermistor and poor current supply to the heater can be solved.

Further, a base heated by a heater, a cover for covering the upper surface side of the base, a handle arranged on the cover and having a hollow terminal portion at the rear, and one end at the rear of the base. A support member having a cover fixed thereto, a conductive member having one end protruding into the terminal portion of the handle and the other end fixed to a terminal portion of the heater, and the conductive member aligned and held at a predetermined position. In addition, since the holding member supported by the supporting member is provided, the temperature rise of the conductive member and the connector joined to the conductive member can be suppressed, and since the holding member is supported by the supporting member, quality and assemblability are improved. Can be improved.

Further, a base heated by a heater, a cover for covering the upper surface side of the base, a handle arranged on the cover and having a hollow terminal portion at the rear, and one end of the handle inside the terminal portion of the handle. And a conductive member having the other end connected to the terminal portion of the heater,
A thermistor connecting member having one end protruding into the terminal portion of the handle and the other end connected to a thermistor for detecting the temperature of the base; and a holding member for aligning and holding the conductive member and the thermistor connecting member at a predetermined position, A temperature control means for controlling the base to an arbitrary temperature by the output signal of the thermistor; a heater control means including the temperature control means; and a connection body having a plurality of conductors connecting the thermistor and the heater circuit, Since the conductive member and the conductor are connected by a screw, a connector in which a contact made of a spring material for transmitting a signal of the thermistor and a terminal for energizing the heater are collectively locked is connected to the thermistor connecting member and the conductive member. When the connector is engaged with a member, the terminal cannot be screwed unless the connector is securely set on the conductive member. Can the current-carrying failure and the like to the thermistor signal transmission failure and heater due to erroneous setting can be prevented.

Since the holding member holds the vertical portion of the conductive member, the vertical rising portion of the conductive member joined to the contact in the connector is not deformed during transportation or assembly, and the rivet made of aluminum is used. Since the conductive member can be fixed to the holding member without using the above, the quality can be improved, and the workability and the assemblability can be improved.

Further, since the vertical portion of the conductive member and the holding member are located rearward from the upper surface of the base, the vertical portion of the conductive member and the holding member can be further separated from the base, and the holding member The temperature rise of the connector can be suppressed.

Further, since the holding member is made of a resin material, the processing accuracy of the holding member can be improved, the conductive member can be held securely, and the holding member is not damaged.

Further, since the conductive member is provided with the cut-and-raised portion which opens downward and is locked to the holding member, the conductive member formed of a relatively thin sheet metal member is not deformed, so that the connector is securely attached to the conductive member. It is possible to provide an iron that can be inserted and set and has no thermistor signal transmission failure or heater failure. Furthermore, since the conductive member is securely held by being set on the holding member without being disengaged by the above-described configuration, it is not necessary to use a fixed component such as a rivet, and the quality is stable and the workability can be improved. .
