Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a cooking device for cooking, for example, white rice, rice, or brown rice.

"Prior art" Conventionally, there was a rice cooker provided with a high frequency generator.

"Problems to be solved by the invention" In the conventional technology, since the high frequency generator is completely incorporated in the rice cooker, a space for incorporating a power transformer, a cooling fan, etc. in addition to the high frequency generator is provided inside the rice cooker. However, there is a problem that it becomes a hindrance to downsizing of the device and that the weight of the rice cooker becomes heavy and it is inconvenient to carry. Furthermore, when the rice cooker is washed with water, water drops accidentally get on the magnetron, and if left in that state for a long time, the metal may rust and deteriorate, shortening the magnetron's life. It was

"Means for solving the problem" Therefore, in the present invention, in the structure in which the high frequency generator is provided in the rice cooker, the generator is a separate unit from the rice cooker, the power input terminal of the generator and the high frequency emission The rice cooker is provided with a power supply terminal and a high-frequency introduction port for detachably connecting the mouth, and the generator is detachably attached to the rice cooker via the power supply input terminal and the high-frequency discharge port.

"Operation" Therefore, since it is not necessary to incorporate the high frequency generator and the parts associated with the generator into the rice cooker, the rice cooker can be easily downsized.

Further, since the unit incorporating the high-frequency generator is detachable from the rice cooker, it is easy to carry when moving the rice cooker from the kitchen to the table.

Further, when washing the lid of the rice cooker with water, the unit incorporating the high frequency generator can be removed, so that water drops will not accidentally adhere to the magnetron and the life of the magnetron will not be shortened.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings. First
FIG. 2 is a cross-sectional side view and FIG. 2 is a plan view. An inner pot (2) heated by an electric rice cooker (1), a main body case (3) into which the inner pot (2) can be freely inserted, The rice cooker (5) is provided with an upper lid (4) for opening and closing the upper surface side opening of the main body case (3),

The rice cooker (5) is provided with a power output terminal (18) that is connected to the control box (15) while being input to the rice cooker (5). 19) is provided in the generator (10), and the drive power of the magnetron (6) provided in the generator (10) is taken in from the rice cooker (5).

Further, the generator (10) is provided with a waveguide (20) which is a high frequency emission port for deriving the microwave from the magnetron (6), and a high frequency wave for detachably connecting the exit side of the waveguide (20). A guide tube (21) serving as an inlet is provided, and the guide tube (21) is provided on the upper lid (4) of the rice cooker (5).

Further, an openable shutter (22) is provided on the outlet side of the guide tube (21) facing the inner pot (2) of the rice cooker (5) and a switching motor (23) for opening and closing the shutter (22) is provided. The shutter (22) is opened to supply the microwave from the magnetron (6) into the inner pot (2) and the shutter (2
The magnetron (6) and the motor (23) are configured to operate in association with the heater (1) so that the rice cooker (1) heats the inner pot (2) by closing (2). ..

Also, as shown in FIG. 2, the hinge (2
4) and the support shaft (25) are provided on the main body case (3), and the inner pot (2) is formed in a substantially octagonal cylindrical shape with a flat bottom and an open top. The inner peripheral surfaces (2a) of are made inwardly convex so that the microwave from the magnetron (6) is reflected by the inner peripheral surface (2a) of the inner pot (2) and diffused.

Further, as shown in FIG. 3, a rice cooking circuit (26) composed of a microcomputer is built in the control box (15), and the switches (11) to (14) and a switch (21b) described later are connected to the rice cooking circuit (26). 26) and the heater (1), the magnetron (6) and the motor (23) are connected to the rice cooking circuit (26).
Connect the heater to the heater based on the preset menu
(1) and magnetron (6) are automatically controlled, and pretreatment and rice cooking are automatically performed by microwave and electric heat.

Further, in FIG. 1, (20a) in the figure is a mica plate which is provided at the outlet of the waveguide (20) to prevent foreign matter such as insects from entering, and (21a) is provided at the inlet of the guide tube (21). (20) A shutter for preventing foreign matter entry that is opened by the mounting operation, and (21b) is the shutter.
A switch for detecting the opening movement of (21a), and (21c) is a mica plate for preventing foreign matter from entering the guide tube (21) outlet.

This embodiment is configured as described above, the inner lid (2) is put in and out by opening and closing the upper lid (4), the object to be heated is put in the inner pot (2), and the output terminal of the rice cooker (5) ( 18) and the input terminal (19) of the high frequency generator (10), and the waveguide (20) and the guide tube (21) are connected to each other, and the high frequency generator (10) is integrated with the rice cooker (5).

Then, use the switch (11) to select the menu and switch
The timer is set by (13) and (14) and rice cooking is started by the switch (12). As shown in the flow chart of FIG. 4, the magnetron is opened by opening the shutters (21a) (22).
(6) is operated (at this time, if the switch (21b) is off, the magnetron (6) is not operated), pretreatment is performed by microwave irradiation, and the shutter ( 22) is closed, the heater (1) is kept warm when rice is not cooked to keep the inner pot (2) at a substantially constant temperature, while the heater (1) is cooked when rice is cooked.
The heater (1) is switched to a heat retention operation after a lapse of a predetermined time.

As mentioned above, rice is cooked by electric heat after pretreatment with microwaves. When cooking brown rice, which has poorer water absorption than white rice, a commercial rice cooker that cooks rice only by electric heat
It took 4 hours and 16 minutes to cook water for 1 hour and 16 minutes with the heater (1), but it took 12 minutes to flood with 500 watts of microwave and 5 hours with the heater (1).
It was possible to shorten the time to 1 hour and 6 minutes by cooking rice for 4 minutes.

In addition, when making red rice using glutinous rice and red beans, it took 1 hour and 10 minutes to soak the rice for 30 minutes and cook for 40 minutes and 17 seconds in the red rice course of a commercially available rice cooker. It was possible to cook red rice in 55 minutes by performing microwave irradiation for 30 minutes, microwave irradiation of 500 watts for 15 minutes, and steaming for 10 minutes.

Also, when cooking azuki beans, it was necessary to soak for about 8 hours, but by irradiating with 90 watts of microwave, it can be soaked in 30 minutes, and beans such as soup powder can be cooked within 2 hours after soaking. did it.
