Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a switch device for a rice cooker used in general households.

Conventional configurations and their problems Conventionally, two types of switch devices have been used for this type of rice cooker: a rice cooking lever that starts and automatically turns off rice cooking, and a power lever that requires power. Things were easy to use. The reason for this is that it is better to have a power lever.
This is because you can turn on the power when you use it, and turn it off when you don't use it while leaving the power cord plugged into the outlet.

However, the important thing about the power lever is that it is normally operated by one person and must be strong, whereas the rice cooking lever is operated by the pressure of a temperature-sensitive thermostat, so it is made of a metal bracelet. It was customary to specify the cutting direction for processing.

In a conventional rice cooker of this type, as shown in Fig. 1, there is a pot 1 for storing food to be heated such as rice, a heating element 2 for heating the pot 1, and a rice cooker depending on the presence or absence of moisture in the pot 1. A heat-sensitive element 3 that detects a temperature rise and a spring pressure inside this heat-sensitive element 3 operate the rice cooking lever 4 to turn off the electricity to the heating element 2.
A device equipped with a microswitch 5 is common.

In addition, in this configuration, the important thing about the power supply is that the power supply micro switch 7 is turned on and off by the operation of the power supply renoku-6, and both the rice cooking lever 4 and the power supply bar 6 are connected to the main body 8.
It is generally provided inside the display panel 9 on the side surface of the display panel 9. 10 is a frame for fixing the power supply microswitch 7 to the main body 8.

FIGS. 2 and 3 show the directions of the edges produced by pressing the power lever 6 and the rice cooking lever 4, and the specific structure of the levers 4 and 6. FIG.

The arrows in FIGS. 2 and 3 indicate the protruding direction of the burr. According to FIG. 2, there is no problem such as malfunction due to the burr, but in FIG. 3, a problem occurs. This is because the rice cooking lever 4, which is operated by the spring pressure of the heat-sensitive element 3,
In FIG. 3, the power lever 6 and the power micro switch 5 are shown.
Since the rice cooker lever 4 is inserted between the frame 16 that fixes it to the main body 8, when the rice cooker lever 4 is in the direction of arrow A, this spring comes into contact with the side surface 6N of the power lever 6, causing malfunction. be.

On the other hand, as shown in FIG. 2, it is convenient if the rice cooking lever 4 is located at the innermost position and in the direction shown in the figure, since malfunctions due to slipping and cracking will not occur.

However, in the structure shown in FIG. 2, as shown in FIG. 4, after inserting the power lever 6 between the frame 10 and the rice cooking lever 4, the 11111111 is passed through. There are two Oka points. This will be explained using FIG. 2.

The first problem is as follows. First, put the rice cooking lever 4 into the frame 1°, and connect the ends 1A74a and 7 of the rice cooking lever 4.
Insert the power lever 6 into the gap S between the frame 10 and the end surface 10a.
However, if the gap S is sufficiently large, both the power lever 6 and the rice cooking lever 4 will be inserted into the shaft 1.
This is inconvenient because the backlash in one direction becomes large.

Therefore, ideally, the gap S is smaller and larger than the thickness of the end surface 6b of the power lever 6, but with this ideal gap, it takes time to insert the end surface 6b of the power lever 6, and alignment It also takes time.

The second problem is that the shaft 11 is connected from the hole 10b of the frame 10 to the hole 6c of the power lever 6, and then to the hole 4 of the rice cooking 1° bar 4.
When passing through the shaft 11 and the respective holes 4b, 60,
10b fits well and is difficult to pass through.

OBJECTS OF THE INVENTION It is an object of the present invention to solve the above-mentioned problem of difficulty in assembly during assembly and to improve work efficiency.

Structure of the Invention In order to achieve the above object, the present invention particularly provides a hole in the frame and the rice cooking lever through which the guide rod passes through, thereby making it easier to insert the power lever and regulating the gap appropriately. It is.

DESCRIPTION OF EMBODIMENTS The present invention will now be described in detail. In Figure 4, 12
14 is the guide rod attached to the jig stand 13, and 14 is the guide rod 1.
2 is a hole provided in the frame 10 to pass through, 15 is a hole 14
This is a hole provided in the rice cooking lever 4 in order to pass the guide rod 12 therethrough.

In the above configuration, when the guide rods 12 are sequentially passed through the holes 14 and 15, the gap S between the end surface 10& of the frame 1o and the end surface 4a of the rice cooking lever 4 is regulated, and if this dimension is set larger than the end surface 6b dimension, , the power lever 6 easily enters the gap S, and the first problem mentioned above is solved.

In addition, by providing the power lever 6 with a hole 16 through which the guide rod 12 is passed, the shaft 11 can be easily passed through, and the frame 101 and both levers 4 and 6 are free from wobbling in the direction of the champion shaft 11. can be prevented. If the shaft 11 has a pointed tip, it will be easier to connect the shaft 11 to each of the holes.

FIG. 5 shows another embodiment. If the tip of the shaft 11 is only pointed, the positioning in the northward direction is done by turning, but if the guide rod 12 is made into a stepped (q-shape) as shown in the figure, the frame 1
Insert the thick diameter part F side into the hole 14 of the cooking lever 4, and insert the thin diameter part part II into the hole 6 of the rice cooking lever 4, and support it with the step on the end face of the hole 15, then the shaft 11 can be passed through even more easily.

Effects of the Invention As is clear from the above-mentioned embodiments, according to the present invention, the frame and the rice cooking lever are provided with a hole through which the guide rod can pass. The power lever can be easily inserted between the frame and the frame.

The gap between the three levers can be moderately regulated,
This allows the shaft to be mounted efficiently.
