[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation knob for setting control values such as temperature and time of an electric heater and an electric cooker.

[0002]

2. Description of the Related Art The structure of an operation knob for setting a control value of a conventional electric warmer, an electric cooker, and the like is disclosed in Japanese Utility Model Publication No. 49-2, which relates to an electric component device having an operation knob and an indicator light.
As shown in FIG. 6 disclosed in the invention of 8478, the operation knob 8 was connected to the shaft 17 to rotate the shaft 17 of the electric component 7 such as a rotary volume.

As an actual product of the operation knob 8 in this case, as shown in FIG. 7, it is fixed to a printed board 21 and incorporated in a lower case 20 of the controller. Although this type of operation knob 8 is a single component, there is also an operation knob composed of two components, and further, as shown in FIG. 8, the operation knob 8 is a two-component of the scale display unit 2 and the knurling unit 4.
Scale display 2 is methacrylic resin, knurl 4 is A
The scale display unit 2 is made of a BS resin and is made translucent.

[0004] Incidentally, the operation knob 8 is actually shown in FIG.
The printed board 2 is attached to the lower case 20 of the controller as shown in FIG.
It is fixed to 1 and incorporated. Since the conventional operation knob 8 is used for both turning on and off the power and setting the control value, the knob is set to “off” when used, and the plug is “unplugged”. Then, when the knob is returned to "OFF" and the knob is to be used again, the knob is turned "ON" and the control value is set again to a desired control value.

[0005] For this reason, there has been a problem that a troublesome operation of remembering a favorite position and adjusting the knob to that position is required each time the device is used. Also, for example, with electric warmers such as electric blankets and electric carpets, there is an operation to set the operation knob to `` strong '' scale at the beginning of use called preheating and to warm up quickly, but after that it is necessary to return the position of the knob to the desired suitable temperature. Each time the user uses the device, he remembers his favorite position and adjusts the knob to that position.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems. When the operation knob is changed from "off" to "on", the operation knob is moved to a desired position. It is an object of the present invention to provide an operation knob that allows the user to always know the position of a favorite dial and easily change the position of an index.

[0007]

The present invention provides a scale display unit.
One side edge is cut circumferentially, and the notch is knurled
And the rotating ring is fitted into the knurled notch
And an operating projection on the outside of the rotating ring,
At the side, attach a convex part to fit the knurl, and further
Operation knob integrated with scale display and cutout
The knurled part is provided and the operation knurled part is rotated.
Rotate the scale display and the rotating ring together to
Controls the heating temperature and only the rotating ring at the controlled position
Rotate to adjust the operation convex part of the rotating ring to the appropriate position.
When turning off the power, turn the operation knurl
When rotating the rotating ring and turning on the power
The rotating ring and the operation knurled part rotate
It consists of an operation knob.

[0008]

[Operation] With the operation knob having the above configuration, if the index of the rotating ring that rotates with the rotation of the operation knob is set to a desired position, the knob is turned on from the off position, and when the knob is moved to the desired position, The index moves with the knob to indicate the desired dial position, and the rotating ring can be moved independently, so the position of the index can be changed.

[0009]

FIG. 1 is a side sectional view of an operation knob according to an embodiment of the present invention, FIG. 2 is a perspective view of FIG. 1, and FIG. 2 is an exploded perspective view, and FIG. 4 is a perspective view in which the operation knob of FIG. 2 is fixed to the printed board of the lower case of the controller and incorporated.
FIG. 5 is a perspective view of a completed controller in which the upper case is assembled to FIG.

First, an operation knob 1 shown in FIGS.
Is used for both the operation of setting control values such as temperature and the operation of turning on / off the power. Of the scale display section 2 of the operation knob 1
Notch one side end circumferentially, and insert the notch 5
The knurled notch 5 has a rotating ring 3
And an operation convex portion 6 is provided on the outside of the rotating ring 3.
On the inner side, a convex portion 9 fitted to the knurl is provided.
Attachment, and combined with scale display 2 and notch 5
The operated knurling unit 4 is provided. In this case,
By pressing the cartridge 4 against the side surface of the notch 5
The operation knurled part 4 has a convex part on its inside and a lock hole 1.
0 is fitted and both are fixed together.
The indicating part 2, the notch part 5, and the operation knurl part 4 are integrated.
Become .

On the other hand, the knurled notch 5
The combined rotating ring 3 has an operating projection attached to its outside.
Rotate the ring 3 by knurling
Can be freely rotated on the notch 5
When the knurled part 4 is rotated,
Since the convex portion 9 is engaged with the knurl of the notch portion 5, it rotates.
The ring 3 is connected to the operation knurling unit 4 and the scale display unit 2.
It will be rotated around .

For example, in an electric heater or an electric cooker,
If you want to heat them, operate the knurled part
Turn the power from “off” to “on” by rotating 4
Then stop rotation at the appropriate temperature. And heating
Turn off the power again to stop heating
First, the operation convex portion 6 of the rotating ring 3 is
The position at the appropriate temperature, that is, the position of the mark A in FIG.
Rotate with. And the position shows, for example, scale 3.
Suppose you have Put the operation knurled part 4 in that state
When rotated in the “off” direction, the rotating ring 3
It turns around and becomes "off" .

Next, let's heat again at the last suitable temperature
When the operation knurled part 4 is rotated,
As before, the rotation ring 3 is tangled around, and the operation projection 6 is
If you stop at the same position as
It can be heated to a degree .

[0014]

According to the operation knob of the effect of the invention The present invention, each use, only previously combined operation convex portion of the rotary ring in the desired position of the scale display portion again before turning off the operation knob
If you want to keep the temperature in the same state as
Possible by simply positioning the operation convex part at the same position as the last time
It becomes. Therefore, the operation knob
It is not necessary to remember the position of
It has the advantage that nothing happens. Something like this
This is possible especially because the configuration of the present invention is adopted.
