Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a high-frequency cooker in which the output of a magnetron or other high-frequency generating source is directed to the entire food being cooked.

(Prior Art) Conventionally, in this type of cooking device, cooking plates C are arranged and housed in at least two levels, an upper side and a lower side, in a heating chamber in a cooking device main body a, as shown in the first diagram, for example. A type is known in which the radio wave supply port f is fully open and connected to a magnetron or other high frequency generation source e through a waveguide d'i on the side surface.

(Problem to be Solved by the Invention) However, in this case, the radio wave supply port f is generally of a type that opens on the top surface of the upper cooking plate C as shown in the figure; There is an inconvenience that high frequency cooking cannot be achieved due to the side cooking plate C.

(Means for Solving the Problems) The object of the present invention is to obtain a cooking device that does not have such inconveniences, and a cooking plate is placed in a heating chamber inside the cooking device body, with the upper and lower sides separated. In a type that can be freely accommodated by arranging it in at least two stages, upper and lower, and having a radio wave supply port connected to a magnetron or other high frequency generation source opened on the side through a waveguide, the supply port is connected to the The waveguide is arranged in at least two upper and lower stages corresponding to the upper and lower two stages of the dish, and the waveguide is configured to be a branched waveguide that is branched into at least two branches and connected to the supply port of each stage. .

(Example) Embodiments of the present invention will be described with reference to attached drawings.

Figure 2 shows one example, where (1) shows the main body of the cooker;
(2) shows the entire heating chamber inside the heating chamber, and inside the heating chamber (2), cooking plates (3) are supported by support members (4) and can be freely accommodated in two levels, upper and lower. Furthermore, a radio wave supply port (7) which is connected to a magnetron or other high frequency generation source (6) via a waveguide (5) is fully opened on the side thereof. In the drawing (
9) shows a door that can be opened and closed at the front of the heating chamber (2).

Although the above is not particularly different from the conventional one, according to the present invention, as described above, the supply ports (7) are arranged in two upper and lower stages corresponding to the upper and lower two stages of the cooking plate (3), The waveguide (branched into 512 pieces, with each stage of the supply port (7) at each tip)
The waveguide was configured as a branch waveguide connected to the waveguide.

More specifically, the supply port (7) is connected to the upper cooking plate (3).
The waveguide (5) is provided in two stages, one above the cooking plate (3) on the lower side of J, and the waveguide (5) connects the supply port (7) on the upper side and the supply port (7) on the lower side at each tip. The output of the source (6) is branched into two, upper and lower, communicating with the upper and lower ports (7), and the output of the source (6) is transmitted through each waveguide (5) and each supply port (7) to the upper and lower ports. The cooking plate (3) and the lower cooking plate (3) were guided so that each high frequency cooking was applied to both (3) (3).

Figure 3 shows a modified example of this, in which case the above-mentioned two
The branch portion of the main waveguide (5) (5J) is provided with a damper (8) that closes one side and the other side in a t-refraction direction.

Thus, the damper (8) can be freely switched between the state shown by the solid line and the state shown by the chain line, whereby the output of the source (6) is reduced to the upper cooking plate (3). ) and the cooking plate (3) on the lower side, it is possible to concentrate the guidance on only one of them, and furthermore, the damper (8) can be placed in the state shown by the solid line and the state shown by the chain line. If the output is alternately distributed and guided to the upper cooking dish (3) and the lower cooking dish (3),
3) It is possible to obtain high frequency cooking at the same time.

The damper (8) may be limited to a plate-like member as shown in the third figure, and its switching rotational state is intended to be the same as shown in the right and left directions.

FIG. 5 shows a circuit diagram of another example, in which it consists of an optical switch and other devices that detect and close the upper cooking plate (3) and the lower cooking plate (3). Each sensor (9
&) (91)), that is, an upper sensor (9a) and a lower sensor (9b), and a drive source σQ that operates to alternately open and close the above-mentioned damper (8) and its operating power source side. intervene in series with each other in the connecting circuit, thus both sensors (
When 9a) (9b) are closed together, i.e. cooking plate (3)
When the cooking plate (3) is located in two stages, the upper and lower stages, the drive source a is energized and the damper (8) is alternately opened and closed; is cut off and the damper (8) becomes a double groove wave tube (5) (5)
On the other hand, for example, only the upper waveguide (5) is kept open and inactive. In the illustrated example, there is a positioning switch (12) that opens and closes in conjunction with the damper (8).
1 is installed in parallel with the lower sensor (9b) described above, and when the damper (8) opens the upper waveguide (5), the switch (121) opens and the damper (8) automatically moves to that position. Made it stop.

(Function) Its operation will be explained with reference to the embodiment shown in the second figure.The output of the high frequency generation source (6) is transmitted through both the upper and lower radio wave supply ports (7 ) (7) onto the upper and lower cooking plates (31 (3), thus both the upper and lower cooking plates (3) (3)
High frequency cooking is obtained above.

Next, to explain what is shown in Figs. 3 and 4, if the damper (8) is set to one or the other switching position, both cooking plates (3) (3) will concentrate only on one or the other. The output is guided to achieve high frequency cooking, and if the damper (8) is switched and controlled in all cycles, the output is dispersed and guided to both cooking dishes (3) (3). High frequency cooking can be achieved with both.

Further, to explain what is shown in Figure 5, when the cooking plates (3) are placed on two levels, upper and lower, the damper (8) is driven by the drive source a [
In this way, high-frequency cooking is performed on the upper and lower cooking plates (3).Next, if only the upper cooking plate (3) is used, the cough damper (8) is obtained with only the upper side open, so that the output is guided only to the upper cooking plate (3) and high frequency cooking is achieved there.

(Effects of the Invention) As described above, according to the present invention, when cooking plates are housed in at least two tiers, an upper side and a lower side, high frequency cooking can be achieved on both sides, eliminating the above-mentioned disadvantages of the conventional one. can get. Furthermore, according to the second invention, a damper is provided at the branch part of the waveguide, and by using this damper as a switching position for one or the other, high-frequency cooking can be obtained only on one or the other of both cooking dishes, It is also possible to periodically control the opening and closing of the damper to achieve high-frequency cooking on both cooking plates at the same time.Furthermore, according to the sixth invention, it is possible to perform high-frequency cooking on only one of the cooking plates depending on the mounting situation of both cooking plates. , and simultaneous cooking of both can be automatically obtained, making it simple and easy to use.
