If the lid αυ is held and the plug (to) is inserted, a timer is set and the system enters a standby state until the telepathy start time.

Then, when it is time to start the 9th effect of 1st drug after 4 immacent,
! The transparent body (7a) is swung toward the drainage side (the side indicated by the two-dot chain line in FIG. 5). As a result, the bottom m opening of the rice washing container (6th) will be closed by the bottom plate (6d) that is interlocked with the conveyor (78).Next, the cell (3b) of the measuring device (3) will be set to a predetermined value based on the rice cooking amount set. The rice is rotated by the number of revolutions, and the rice is measured and washed through the chute (4)! Injected into (da). After that, the odor control valve (5d) operates and the container (6
8), and at the same time the stirring rod (6b) is rotated to wash the rice. At this time, the bottom opening of the rice washing container (6a) and the bottom plate (6d) are not completely sealed, allowing some water to leak out. As a result, the washed rice is drained out of the main body (1) from the drainage receiver (9) through the conveyor (7a) in sequence. Such rice washing is repeated until the turbidity of the waste water becomes less than a predetermined value or a predetermined time elapses, and after the final rice washing, the 5θ valve is closed.

Stops operation until drainage is complete. Then, the carrier (
7a) is swung so that the left side (7C) is facing down, and the rice washing container (
68) is open at the bottom. Then, the control valve (5e) is opened for a predetermined period of time, and water is supplied into the container (6 days).
6a) and the rice that adhered to the conveyor (78) are poured into the rice cooker.9 Next, the rice and the corresponding water are added to the rice cooker. The water is oscillated and water is supplied only for a specified period of time.

Post-cleaning is performed. The position of the carrier (7a) is determined by the detection switches (8a) and (8t), and is precisely controlled by the control device 6υ. On the other hand, rice cooker αυ
The rice inside was raised like a mountain, and motor 1
When the eccentric cam (9) rotates due to the drive of It is closed by its own weight. After that, a waiting time is taken to soak the rice in water for a predetermined time, and power is supplied to the rice cooker a1.

The above is the case when the rice cooking switch (42b) is selected, but when the rice measuring switch (42a) is selected.

The conveyor (78) is swung from the front spinning to the rice cooker Il side.

The rice is weighed as described above, and the weighed rice passes through the rice washing container (6a) and is transferred to the rice cooker a via the conveyor (7a).
1, and the lid α9 is closed.

Also, when the rice washing switch (42c) is selected.

The steps up to power supply to the rice cooker (11) are performed when the rice cooking switch (42b) is selected.

[Problem to be solved by the invention]

Conventional fully automatic rice cookers like the ones above don't work well when cooking rice.
Since the plug detector (tor) such as a photo sensor detects whether the pillow plug (to) is inserted into the outlet 4, insertion is detected even if the plug (2) is not inserted enough. It happens.

There is a problem that cooking rice becomes impossible.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a fully automatic rice cooking device that can prevent accidents in which rice cannot be cooked due to insufficient insertion of the 9Ml source plug.

[Means for resolving issues]

The fully automatic rice cooking device according to the present invention has a lever formed in a substantially L-shape pivotally mounted inside the main body, and when the power plug connected to the rice cooker is inserted into the electrical outlet, one end of the lever is engaged. The detection switch is operated by interlocking displacement of the other end.

[Effect]

In this invention, the detection switch is operated in conjunction with the insertion and engagement of the power plug.
If the F source plug is not fully inserted into the outlet, the other end of the lever will not be displaced enough to operate the detection switch.

Figure 1 is a detailed view of the part, Figure 2 is a front view of the outlet, Figure 3 is a left side view of Figure 2, and Figure 4 is the ff- of Figure 2.
This is a cross-sectional view of IV information, and parts similar to those of the conventional device are designated by No. 9. Note that FIG. S is also used in this embodiment.

In the picture, is Ikiri anju? flK is a fixed mounting plate, to which the outlet ■ is fixed, and a groove (38a) is provided on its surface.l4L3 is a lever formed in an almost L-shape, and its bent part is attached to the mounting plate i49. One end (45a) is positioned in front of the outlet, and the other end (46b) is located on the back side of the mounting plate. is the support plate fixed to the back of the support plate 0!19 (4'J is the detection switch fixed to the support base).

The spring is a push spring installed between the other end of the lever throat (46b) and a spring receiver (48a) that serves as a support plate ha.

In the fully automatic rice cooking device configured as described above, when the plug (to) is not inserted into the outlet (to), the lever terminal is pushed by the push spring (■) as shown by the solid line in Fig. 4~). position, and the detection switch is not operating.

The plug (to) becomes an outlet (to)! 6, which is important, press the lever and move it clockwise to one end (46a)
1 into the plug and enters the groove (38a) at the bottom of the outlet.

On the other hand, the ftb end (46b) of the lever 61 is displaced against the force of the restraining spring ω, and the detection switch 41 is operated. With this, it is possible to detect that the plug C(l) has been inserted into the outlet.

In other words, unlike plug detectors composed of photo sensors, etc., the detection switch (I) does not operate unless the plug (to) is securely inserted into the outlet (to), so there is less risk of false detection (Nararu). Moreover, since an amplifier circuit or the like is not required, costs can also be reduced.

〔Effect of the invention〕

As explained above, in this invention, a lever formed in an approximately L-shape is installed, and when the power plug of the rice cooker is inserted into an outlet, one end of the lever engages and the Fl! l!
Since the detection switch is activated by the interlocking displacement of the end, the accuracy of detecting the insertion of the power plug into the outlet can be increased to prevent accidents in which rice cannot be cooked due to insufficient insertion of the power plug. This has the effect of reducing costs compared to other components.
