Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) This invention relates to a front dial type iron that has a temperature setting knob on the front of the handle, and in particular, an automatic temperature adjustment that is provided on the temperature setting knob and the base. The present invention relates to an iron having a function of holding an interlocking rod that connects the utensils upright.

(Prior Art) As a conventional dial type iron, there is an iron shown in FIG.

This iron includes a base 1, a base cover 2 covering the base 1, and a handle 3 attached above the base cover 2, and an automatic temperature regulator 4 is provided on the upper surface of the base 1. This automatic temperature regulator 4 consists of a bimetal 5, a fixed contact plate 6, and a movable contact plate 7.
The contacts of the movable contact plate 7 are brought into contact and separated according to the curved deformation of the
The energization of the heating element 8 provided on the base 1 is controlled.

9 is a temperature setting knob attached to the front part of the handle 3, and this temperature setting knob 9 is connected to the support plate 11 of the fixed contact plate 6 of the automatic temperature regulator 4 via an interlocking rod 10.
By operating this temperature setting knob 9 from side to side, the support plate 11 can be moved up and down to convert the set temperature of the base 1 to various temperatures. When power is applied to the heating element 8 via the heating element 8, the heating element 8 generates heat, and the base 1 is gradually heated. When the base 1 reaches a predetermined temperature, for example 160°C, set by operating the temperature setting knob 9,
Contact 12 turns OFF due to bending deformation of bimetal 5
As a result, the power supply to the heating element 8 is cut off. and
When the temperature drops to about 150° C., the bimetal 5 senses the temperature drop in the base 1 during this time and turns on the contact 12 again, thereby recovering the temperature of the base 1.

In such conventional irons, the interlocking rod 1
0 must pass through the free through hole 2a formed in the base cover 2.

Generally, in the case of a front dial type, a cam surface is formed on the temperature setting knob 9, and the displacement of the cam surface 13 is transmitted to the automatic temperature controller 4 via the interlocking rod 10 by rotation of the temperature setting knob 9. The upper end of the interlocking rod 10 is brought into contact with the cam surface 13 through the guide hole 14 provided in the handle 2 without shifting in the front, back, left and right directions, and the upper end of the interlocking rod 10 A hole is formed in the support plate 11 of the automatic temperature controller 4, and the lower end portion is inserted into the hole 15. Therefore, the movement of the interlocking rod 10 is limited to vertical movement only by the hole 14 of the handle 3, and the indicator plate 11 of the automatic temperature controller 4 moves in an arc at the lower end, so that the lower end and the support are controlled. This is because the holes 15 in the plate 11 require a certain dimensional tolerance a. In addition, 1 in the figure
6 is a presser plate for the temperature setting knob 9, and 17 is an adjustment screw.

(Problems to be Solved by the Invention) In the prior art, due to the dimensional tolerance a, the interlocking rod 10 is tilted at an angle θ as shown by the line at the time of assembly, which poses a problem when assembling the iron. This is because the upper end of the interlocking rod 10 is in contact with the cam surface 13 after assembly, so the interlocking rod 10 is held substantially upright, but during assembly, the interlocking rod 10 is held in a substantially upright state. It occurs because there is no.

For this reason, in the past, a jig or the like had to be used to make the interlocking rod 10 independent during assembly, resulting in a problem of poor workability.

This idea was developed in view of the above problems, and includes a base with a heating element, a base cover that covers the base, a handle attached above the base cover, and an automatic temperature controller on the top surface of the base. In the iron, a temperature setting knob is provided at the front part of the handle, and an interlocking rod that connects the knob and the automatic temperature controller is provided so as to pass through the free through hole formed in the base cover in an almost upright state. The purpose is to have an upright holding function so that the interlocking rod can stand on its own in the free through hole.

[Structure of the idea]

(Means for Solving the Problems) In this invention, a protrusion 22 is formed on the base cover 2 provided on the base 1, and a loose through hole 2a of the interlocking rod 10 is provided at the top of the protrusion 22, so that the interlocking rod 1
0 penetrates the free through hole 2a in a substantially upright state.

(Function) With the above configuration, when the handle 3 and the like are mounted on the base 1, the interlocking rod 10 is held in a substantially upright state by the loose through hole 2a, thereby improving assembly workability.

(Example) An example of this invention will be described based on FIGS. 1 and 2. Components having the same functions as those in FIG. 3 are given the same numbers, and detailed explanations will be omitted.

A heating element 8 such as a mica heater is placed on the top surface of the base 1.
is fixed by a boss 18 via a heating element holding plate 19. An automatic temperature controller 4 is attached to the base 1,
An elastic plate 20 is connected to the proximal end of the support plate 11 and constantly biased upward.

A pyramidal or conical upward protrusion 22 is formed near the front of the thermosetting resin base cover 2 that covers the base 1, and a free through hole 2a for the interlocking rod 10 is formed at the top of the protrusion 22. . A temperature setting knob 9 is provided at the front part of the handle 3, and a cam surface 13 is formed on the lower surface of the temperature setting knob 9. The temperature setting knob 9 is pressed from above by a temperature setting knob holder 16 via a spring washer 23, and is screwed onto a boss 24 protruding from the handle 3 with a screw 25.

An adjusting screw 2 is provided at the lower end of an L-shaped interlocking rod 10 that connects the temperature regulator 4 and the temperature setting knob 9.
6 is clamped and fixed by a holding pin 27, and this adjusting screw 26 is inserted into a through hole 15 formed in the support plate 11 of the automatic temperature controller 4.

On the other hand, the upper end of the interlocking rod 10 passes through the free through hole 2a and has an inverted conical hole 1 formed inside the handle 3.
4 and comes into contact with the cam surface 13 of the temperature control knob 9. In order to adjust the adjusting screw 26 with a screwdriver or the like, a through hole 28 is formed in the base cover 2, and the upper end of the adjusting screw 26 protrudes from this through hole 28, and a through hole 29 is formed in the handle 3. A cover 30 such as a decorative name plate is provided to cover the hole 29.

The above embodiment has such a structure, and as shown in FIG. 2, a pyramid-shaped or conical projection 22 projects from the upper surface of the base cover 2, and a free through hole 2a is provided at the top of the projection 22. So interlocking rod 10
The inclination limit angle θ' is regulated, and even when the dimensional tolerance a is the same, the inclination θ can be made smaller than the conventional inclination θ (θ'<θ), and the interlocking rod 10 can be maintained in an almost upright state during assembly. Therefore, the interlocking rod 10 and the base cover 2 are attached to the base 1 to which the automatic temperature controller 4 is attached.
When assembling the handle 3 and the like after attaching the handle 3, it is possible to easily assemble the interlocking rod 10 without the need for a jig to keep it in an upright state. Further, since the protruding free through hole 2a is formed integrally with the base cover 2 from thermosetting resin, it can perform its holding function without requiring any special member, and can be manufactured at low cost. Furthermore, by forming a guide hole 14 corresponding to the free through hole 2a of the base cover 2 on the handle 3 side, when the upper end of the interlocking rod 10 is brought into contact with the cam surface 13, the position of both can be confirmed. At least, the upper end of the interlocking rod 10 is guided to the cam surface 13 by the guide hole 14, and can be set simply by inserting the upper end of the interlocking rod 10 into the hole 14.

It should be noted that the present invention is not limited to the embodiments described above, and various modifications can be made within the scope of the gist of the present invention.
