Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a timer device for an electric cooker for cooking rice and the like.

BACKGROUND OF THE INVENTION A conventional timer device for an electric cooker is known from, for example,
As shown in Japanese Patent No. 49630, the structure was as shown in FIG. That is, the timer motor 2 is fixed with screws 3 within the display panel 1 of the electric cooker. The scale panel 4 on which the scale is printed is attached to the display panel 1.
It is adhered to the front recess 1a with a pressure-sensitive adhesive or the like. A timer shaft 6 of the timer motor 2 projects forward from the display panel 1, and a dial knob 6 can be completely fitted onto the timer shaft 6. This dial knob 6 is made of a translucent material and has an elongated recess 6a into which a red color can be inserted on the back side. A red line formed by filling the recess 6a with red color serves as a mark when setting the time. Further, it is customary to adhere a plate 7 on which a warning message is printed to the front recess 6b of the dial knob 6.

Problems to be Solved by the Invention In such a conventional configuration, when setting the timer, it is common to set the time to the number on the scale panel 4, but since the rotation speed of the timer motor 2 is proportional to the frequency. , two types of screens, one for 60Hz and one for 60)tz, are printed on the same side, so in this case the numbers are smaller,
It was hard to see. It was particularly difficult to use for visually impaired people.

In addition, in order to keep the rotation speed of the timer motor 2 constant,
It is also possible to control it using a microcomputer, etc., but in this case, it is not possible to share it with conventional parts,
There were problems such as a longer development schedule and an increase in the number of parts, which went against the goal of resource conservation.

The present invention solves these problems by making it possible to make the numbers for 50Hz and 60 ratio on the scale panel larger and easier to see, and also to make it easier to see the numbers around the timer.
The number of control parts can be shared with the conventional one, and it is cheaper than the 60 yen area.
0) When moving to the h area, the purpose is to be able to easily change the display on the scale panel, and also to prevent damage to the scale plate when changing the scale plate.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a display board that is fixed to the side surface of the main body of an electric cooker, has a circular recess in the front, and further has a hole in the center of the recess. a timer fixed inside the display board and having a shaft at the center of the central hole of the recess of the display board; a knob fitted into the shaft of the timer; and a knob fitted into the recess of the display board. a ring-shaped scale plate for 60 ratio that is fixed and is separated at one place; a ring-shaped scale plate for 60) h that rotates and slides in the recessed part of the display plate and is separated at one place; Scale plate for 60an and 6
and a scale plate holding ring that fits into the center hole of the 0- scale plate and is fitted and fixed in the center hole of the recess of the display plate, and , said 50
The 6° Tagawa scale plate is made to protrude and slide from the cut-off end face, and the hole provided near the outer periphery of the end face of the 6° Tagawa scale plate is a non-penetrating blind hole.

Function According to the above configuration, it is possible to easily convert from a 60- display to a 60-use display or from a 60) (z display to a 60-use display) within the front recess of the display board, and the outer periphery of the end face of the 60-an scale plate can be easily converted. The hole provided nearby is a non-penetrating blind hole, so even if you rotate and slide the scale plate for 5ol-1 with something with a sharp tip, such as a bamboo comb, the existence of this blind hole will cause It is also possible to prevent scratches on the surface of the 50-an scale plate.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 7.

In FIG. 7, 1o is the main body of the electric cooker, and a display board 11 on which cooking contents (not shown) are written is fixed to the side of the main body 1o. Inside this display board 11 is a board 12.
The timer 13 is fixed via. This timer 13
As shown in FIG. 1, the shaft 13a is D-cut.

Reference numeral 14 denotes a knob that fits onto the D-cut shaft 13a and operates the timer 13.The details of the knob 14 will be explained next with reference to FIG. Reference numeral 14a is a matching groove formed by adding color to the recess on the back surface of the knob 14 made of a transparent material. Reference numeral 15 denotes a scale plate for 50 Hz on which a display for 50 Hz is printed, and this scale plate 1a for 50 Hz is configured in a ring shape, and a part of the ring is separated. 15a is this cut-off end face. This is a scale plate for 60) h with the display for 601-12 printed on it.
Part of the ring has also been cut off. 16a is this cut-off end face. 16b is a projection provided on the inner circumference of the ring of the scale plate 15 for 60 fields, and this projection 16b is located in the hole 11b located in the center of the circular recess 11a on the front surface of the display board 11.
The protrusion is inserted into the protrusion recess 11c provided on the outer periphery of the protrusion and rotated. Reference numeral 11d denotes a rotation stopper that restricts rotation on a fixed plate when the 60 field scale plate 16 rotates.

17 is a scale plate holding ring, and this scale plate holding ring 17 is fitted into the center hole 15C provided in the scale plate 15 for 50mm and the center hole 16b provided in the scale plate 16 for 60mm,
Furthermore, a claw 17a for fixing to the hole 11b of the display board 11 and a rotation stopper 17b are provided. And correct rotation 17b
fits into the groove 118 of the display board 11.

Figure 2 shows details of the scale plate 15 for 60 fields.
Reference numeral 6d denotes a notch formed on the outer periphery of the end face 15a, which is constructed by cutting off a part of the ring constituting the 50Hz scale plate 15; This serves as an escape for the hole 16C provided near the outer periphery.

This hole 16C is a non-penetrating blind hole, so that when rotating and sliding the 6o scale plate 16 with a wood or bamboo comb, etc.
It is deep enough to accommodate the bamboo comb, etc.

Figure 4 shows a scale plate 1 for 60 l under the scale plate 16 for 60 l.
6 are overlapped and the end surface 16a is inserted into the end surface 16a. When the tip of a nail or bamboo comb is inserted into the hole 16c provided near the outer periphery of the end surface 16a and rotated counterclockwise, The scale plate 16 for 60Hz is the scale plate 1 for 50Hz.
5.Slide on top.

This state is shown in FIG. If the rotation is continued from this state, the state shown in FIG.
01 scale plate 15, and its display is converted.

From the state shown in Fig. 6 above, move the scale plate 16 for 60 fields clockwise.
If you turn the
01 can be easily converted. Also 6
Even if the 0-display and the 60-an display are reversed, the same effect can be obtained.

Effects of the Invention As described above, according to the present invention, either the 50 ratio scale plate or the 60 ratio scale plate can be freely raised upward, and as a result, each displayed number can be increased. ,
Even elderly people with visual impairments can set the time more easily than before. Further, the timer motor may be proportional to the same frequency as the conventional one, so there is no need to provide parts for automatic frequency switching on the control circuit board, and parts can be shared and the number of parts can be reduced. 5 more
Even when moving from a 0 yen district to a 60 yen district, the display can be easily converted.

In addition, the holes provided near the outer periphery of the end face of the 60 ratio scale plate are blind holes that do not penetrate, so even if the 60 ratio scale plate is rotated and slid with a sharp object such as a nail or bamboo comb, Due to the existence of this blind hole, it is possible to prevent scratches on the surface of the 60) (z scale plate, and when turning with strong force, nails, bamboo combs, etc. can be easily removed from the blind hole. Since it comes off, the scale plate itself is less likely to be destroyed, and as a result, it can be used conveniently for a long period of time, and has various excellent effects.
