BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fully automatic rice cooker in which a rice washing / cooking process is integrated, and more particularly to a rice cooker in and out.

[0002]

2. Description of the Related Art Conventionally, in this type of fully automatic rice cooker,
There has been proposed a fully automatic rice cooker including a rice bin for storing rice, a rice washing section for washing rice while stirring rice and water with stirring blades, and a rice cooking section for cooking the washed rice.

[0003] The applicant has made a series of rice washing / transfer / cooking control for executing steps such as (transfer to rice washing section), (rice washing), (transfer from rice washing section to rice cooking section), and (rice cooking) from a series of rice bottles. In a fully automatic rice cooker equipped with a device, a tray for receiving rice bran and crushed rice generated when transferring rice under a rice bin is provided, and a lid of the rice cooker is automatically opened and closed at a rice cooking position in the device. An automatic rice cooker has been proposed as a prior application.

[0004]

However, in the rice cooker of the above-described fully automatic rice cooker, when rice is cooked up to 1 sho at a maximum, the rice, water and the weight of the rice cooker main body are about 10 times.
kg, which made it very difficult for the user (housewife) to put the rice cooker in and out.

[0005] The present invention has been made in view of the above problems, and aims to reduce the burden on the user when putting the rice cooker in and out by moving the elevator up and down by a driving device. It is.

[0006]

Means for Solving the Problems To achieve the above object, a fully automatic rice cooker according to the present invention comprises a rice bin for storing rice, and a rice washing section for washing rice while stirring rice and water with stirring blades. And a rice cooker for cooking washed rice.
A drawer that moves horizontally out of the fully automatic rice cooker body,
An elevating table for elevating and lowering the rice cooker placed on the tray;
A driving device for moving the platform up and down, and
The rice cooker lid can be opened when the rice cooker is raised.
Lid open switch .

[0007]

In the fully automatic rice cooker having the above-described structure, the rice cooker can be easily taken in and out by moving the elevator up and down by the driving device.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the fully automatic rice cooker of the present invention will be described in more detail based on embodiments. FIG. 1 is a sectional view of the right side of a fully automatic rice cooker 1 of the present invention at a position of a rice bin. Open the inlet 11 above the rice bin 10 and put rice. The introduced rice enters the rice bin 12. When cooking rice,
The amount of rice to be cooked (for example, 2 go) is transferred to the upper portion by the spiral 15 directly connected to the motor 14 and the transfer tube 16 from the notch 13 at the lower portion of the transfer tube 16.
Transfer to the rice weighing department from 7.

Reference numeral 21 denotes a fine mesh wire mesh, for example, having a sieve size of about 1 mm, which is finer than the diameter of the rice provided at the lower part of the rice bin 12, and is made of crushed rice, rice bran, or originally crushed rice generated at the time of transfer. , Rice bran and the like fall through it and are stored in the drawer-type tray 22. An infrared level sensor 23 is installed on the tray 22, and when this level becomes higher than a certain level, this is displayed on an LED of an operation panel (not shown), and an instruction is given to discard the ground rice and rice bran. When this display appears, the tray 22 is pulled out and the crushed rice and rice bran are discarded. Rice is weighed in the weighing section,
After the rice is washed in the rice washing section, it is put into a rice cooker and cooked, but the description of this part is omitted because it is not directly related to the present invention.

In FIG. 2, the rice cooker cooks rice at the leftmost position. When the rice cooking is completed, the rice cooker 51 is moved below the rice washing section 30 by the rice cooker moving device 53 (motor and rack), and then the drawer 56 is pulled out toward the front, and the punter elevating table 52 is driven as shown in FIG. Then, only the platform to the left of the switch 57 shown in FIGS. 2, 4 and 5 is raised upward.

Then, the push button 5 for opening the rice cooker lid
When 7 is pressed, the lid open switch 58 of the rice cooker 51 is pressed, so that the lid of the rice cooker can be opened and the rice can be eaten on the spot. Of course, it is also possible to lift the rice cooker 51, bring it to the table, open the lid of the rice cooker 51, and cook rice. Open push button 57
As shown in FIG. 4 and FIG. 5, normally, the male spring 57a does not hit the lid open switch 58 of the rice cooker.

FIG. 6 shows a first example of a driving device for the pant elevator 52.
In the example, the lower left portion of the panta 59 of the panta lift 52 is driven while being pulled by the motor 61 connected to the wire 60. When the drawer 56 is pulled out, the motor 61 is turned on and the lift 52 is At the top. Then, when the rice cooker 51 is placed, the motor 61 is turned off, and the lift 52 is gently lowered by the weight of the rice cooker 51.
Thereafter, if the drawer 56 is pushed in, the rice cooker 51 can be easily set.

FIG. 7 shows a second example of a driving device for the pant elevator 52, in which a hydrogen storage alloy is used in place of the motor 61 of the first embodiment. A heater (not shown) is provided outside of the cylinder 63, and the power to the heater is controlled to change the temperature of the hydrogen storage alloy 62. The lifting table 52 is moved up and down using the form change of the storage alloy 62 as a drive source.

FIG. 8 shows a third example of a driving device for the pant elevator 52, in which a shape memory alloy 64 is used instead of the motor 61 of the first example. The lifting table 52 is moved up and down by using a change in form due to a change in temperature at the time of the operation as a driving source.

[0015]

[Effect of the Invention] Since the fully automatic rice cooker of the present invention has the above-described configuration, the elevator on which the rice cooker is mounted is automatically moved up and down by the driving device, so that the rice cooker can be easily taken in and out. be able to. In addition, the lid open switch is
Open the rice cooker lid with the rice cooker raised by the platform
To make it operable, cook rice with the rice cooker pulled out.
Prevents accidentally opening the rice cooker lid before raising the cooker
it can.
