Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a high-frequency cooker, and more particularly to a structure of a new-type high-frequency cooker for cooking cooked food by high-frequency.

[Prior Art] In a kitchen or the like of a home or various restaurants, a high-frequency cooker for heating cooked food is used as a microwave oven or the like.

FIG. 4 shows a schematic configuration of a conventional high-frequency cooker. In the figure, (1) is a main body, (2) is a cooking chamber for storing and cooking food, and (3) is cooked food. A rotary table to be placed, (4) is a magnetron for generating high frequency microwaves, (5) is the magnetron (4)
Waveguide that guides the high frequency generated in the cooking chamber (2), (6)
Is an operation panel, (6a) is a start switch for starting the operation of heating and cooking, (6b) is a setting switch for setting the operation time, and (7) is a door for sealing the inside of the cooking chamber (2).

According to such a conventional cooker, the cooked food is placed on the turntable (3), the door (7) is closed, and the setting switch (6)
By pressing the start switch (6a) while adjusting b) to a predetermined time, heating cooking is started. Then, a high frequency is generated by the magnetron (4), and this high frequency is radiated into the cooking chamber (2) through the waveguide (5).

Since the rotating table (3) rotates while the cooked food is placed, the high frequency is uniformly radiated to the cooked food, which allows the food to be cooked.

[Problems to be Solved by the Invention] By the way, a conventional general high-frequency cooker has a box-like structure as shown in FIG. 4, and a door (7) is provided in front of it. Therefore, it is relatively inconvenient to get food in and out.

That is, the cooking chamber (2) is designed to have a volume as small as possible in order to radiate a high frequency or to make the entire cooking device compact. Also,
The door (7) is formed so as to open one surface of the box in order to prevent leakage of high frequencies or inevitably.

Therefore, it is relatively troublesome to put food in and take it out from the one surface of the box in the small-sized cooking chamber (2), and conventionally, there is a problem that the food should be put in and taken out more easily. is there.

Moreover, since the conventional high-frequency cooker is a box as shown in FIG. 4 and is relatively large, the sled is installed only on the refrigerator or the like, and the degree of freedom is low. Therefore, when the high-frequency cooker is not used, there is a problem that it takes up a relatively large space, and there is a problem that a simple structure should be used.

Therefore, the present applicant intends to provide a new type of high frequency cooker, and in this case also, it is possible to prevent the high frequency from leaking from the cooking chamber (2) to the outside when the door or the lid is opened. There is a need. Therefore, it is preferable to take measures to prohibit the operation of the high frequency generator when the lid is completely opened or when the lid is not closed sufficiently.

The present invention has been made in order to solve such a problem, and it is possible to obtain a high-frequency cooker in which cooking food can be easily taken in and out, and which has a high degree of freedom in installation location, and outputs high frequency when the lid is not closed. The purpose is to obtain a high-frequency cooker that does not.

[Means for Solving the Problems] In the high-frequency cooker according to the present invention, an upper lid for forming a cooking chamber for taking in and out cooking food and for enclosing high-frequency waves is detachably provided from the main body and is provided on the outer peripheral portion of the main body. It has a safety switch that allows and prohibits the generation of high frequencies by operating in accordance with the vertical position of the peripheral portion of the upper lid. The outer peripheral portion of the upper lid is formed in a circular shape, and three or more safety switches are provided so that any one of the safety switches operates even when the upper lid is tilted.

[Operation] According to the above configuration, when the upper lid is opened, the upper lid is completely removed from the main body, so that the upper portion of the main body is widely opened, and cooking food can be easily taken in and out.

Further, since the upper lid and the main body are separated, it is possible to attach the main body only to another element such as a table and use the upper lid appropriately only during cooking.

Further, in the cooking device of the present invention, since the peripheral portion of the upper lid is circular and three or more safety switches are provided, when the upper lid is opened and closed while tilting, all the opening and closing operations of the upper lid are performed. It is possible to add an operation stroke of time until the safety switches of the above are sequentially operated.

Therefore, when the upper lid is completely closed to the main body, three or more safety switches operate so as to allow generation of high frequency, but at this time, if the upper lid is tilted and is not completely closed, either The safety switch operates to prohibit high frequency output.

[Embodiment] A preferred embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows the structure of a high-frequency cooker. (10) is a main body, (11) is a case of the main body (10), and (12) is an upper lid which is a feature of the present invention. This upper lid (12)
Is formed to have a size serving as a food preparation room, and the entire upper lid (12) or only the inner surface thereof is formed of a metal plate to confine high frequencies. Further, in the embodiment, the upper lid (12)
Ventilation holes are opened in the wall surface of. (13) is the upper lid (12)
A handle for attaching / detaching to / from the main body (10) and a discharge tube (14) provided on the upper lid (12) for making the cooking chamber bright.

Reference numeral (15) is a food placing table, which is attached via a packing (16) so as to fit into a groove formed in the support plate (17).

(18) is one of the microswitches provided as a safety switch, which is a feature of the present invention.
0) is arranged near the inner surface of the case (11) in the outer peripheral portion. In the embodiment, as shown in FIG. 2, three micro switches (18-1), (18-2), (18-
3) are provided at equal intervals. Reference numeral (19) is a protector integrally formed with the case (11) for protecting the actuating piece (18a) of the micro switch (18), and the peripheral portion of the upper lid (12) is for actuation of three safety switches. By pressing down the pieces (18a-1), (18a-2), (18a-3), the generated output of high frequency is allowed.

Further, (20) is a high voltage transformer, (21) is a high voltage condenser, (22) is a magnetron for generating high frequency,
(23) is a radiation fin for diffusing heat generated in the magnetron (22), (24) is an antenna for radiating high frequency to the cooking chamber, (25) is cooling for cooling the magnetron (22) and the high voltage transformer, etc. Fan, (26)
Is a blower motor for driving the cooling fan.

The first characteristic of the present invention is that the conventional door for loading and unloading cooked foods from the high-frequency cooker is replaced by the upper lid (1).
2), the upper lid (12) has a volume for forming a cooking chamber for cooking food, and the upper lid (12) is detachable from the main body (10) to prepare a cooking chamber for cooking food. That is, it is possible to easily and easily take it in and out.

Therefore, at least the upper lid (12) is configured so as to open a space of a part or the whole of the upper surface and the side surface of the conventional cooking device, and in the embodiment, the upper surface and the entire side surface are opened. It is configured to open.

Further, in the embodiment, the outer peripheral shape of the upper lid (12) is circular so that the upper lid (12) can be easily attached and detached.
That is, if the outer peripheral shape is a square shape, the upper lid (12) becomes directional, so the upper lid (12) must be opened and closed while matching the shape of the main body (10) side. Therefore, if the outer peripheral shape is circular, the directionality is lost and the upper lid (12) can be easily opened and closed.

In this way, the following advantages can be obtained by making the shape circular. That is, a high frequency is radiated to the cooking chamber in the upper lid (12), but this high frequency may leak from the joint between the upper lid (12) and the main body (10), and this leakage must be prevented. However, in the case of the square shape, a gap or the like is likely to be formed in the corner forming portion, which makes it difficult to prevent high frequency leakage. Therefore, if the outer peripheral shape is circular, high frequency leakage can be easily prevented and the design and manufacture of the upper lid (12) can be simplified.

The second characteristic of the present invention is that the peripheral portion (12a) of the upper lid (12) is also circular in order to effectively prevent the output of high frequency when the upper lid (12) is tilted and is not completely closed. That is, three or more switches are provided.

That is, in the embodiment, as shown in FIG. 2, three micro switches (18) are provided as safety switches on the inner surface of the circular case (11) of the main body (10) at intervals of 120 degrees. . As a result, the operation stroke of the time until the three micro switches are sequentially operated can be given to the opening / closing operation of the upper lid, and the upper lid (1
Even if 2) is inclined and opened for some reason, the high frequency is not leaked to the outside.

FIG. 3 shows an electrical connection state of the safety switch. As shown, three micro switches (18-) are provided between the magnetron (22) and the outlet (31).
1), (18-2), (18-3) are provided, of which
The two micro switches (18-1) and (18-2) are switches that mechanically turn off when the top cover (12) is opened, and the remaining micro switches (18-3) are the top cover (1
When 2) is opened, it is turned on, and when both of the two micro switches (18-1) and (18-2) have a failure, or when the fuse is turned on, the fuse (3
2) It is a switch for skipping and electrically disconnecting.

Therefore, these safety switches are magnetron (22)
Is installed separately from the start switch (6a), and when the micro switches (18-1) and (18-2) are in the on state and the micro switch (18-3) is in the off state, the start switch The magnetron (22) can be operated by (6a).

The embodiment is configured as described above, and its operation will be described below.

When heating the cooked food, the handle (13) is grasped to open the upper lid (12), and either one of the two micro switches (18-1) and (18-2) is turned off. The output of the magnetron (22) is prohibited depending on whether the micro switch (18-3) is turned on. Therefore, any one micro switch (18)
If is not pushed by the upper lid (12), high frequency is not output even if the operating switch of the cooking device (not shown) is mistakenly operated.

Then, the food to be cooked is placed on the food placing table (15), and the upper lid (12) is the main body (10).
Since it has been completely removed from, food can be easily placed.

After placing the cooked food on the food placing table (15), the upper lid (1
When 2) is closed as shown in the figure, the circular periphery (12a) is the operating book (18a-1) of the microswitch (18),
Since the (18a-2) is pushed down to be turned on and the remaining actuating piece (18a-3) is pushed down to be turned off, the generation of the magnetron (22) is allowed. For example, as shown in FIG. 2 (b), when the upper lid (12) is slanted and is not completely closed, the micro switch (18-1) is turned off, so that high frequency is not output, Further, even if a part of the upper lid (12) is accidentally opened during cooking by heating, high frequency is not generated.

Then, when the cooker is activated, the magnetron (22)
And the high frequency is output from the antenna (24), the high frequency is radiated into the cooking chamber formed by the upper lid (12), and thereby the food is heated and cooked.

The high frequency is confined in the cooking chamber by the upper lid (12) formed of a metal plate, and the high frequency does not leak outside.

Further, in the present invention, the upper lid (12) is configured to be attachable to and detachable from the main body (10), so that the following usage can be performed in addition to the conventional usage. That is, the main body (10) is embedded in the center of the dining table, the upper lid (12) is usually removed, and the upper lid (12) is used only when it is used as a cooking device. Then, when the cooker is not used, the main body (10) serves as a plate or a table, and when heating is performed, the upper lid (12) is used to easily heat and cook on the dining table. be able to.

As described above, according to the present invention, the main body (10) and the upper lid (12) can be separated from each other, so that the main body (10) can be placed on the cooking table or other places.
Can be embedded. Therefore, there is an advantage that a high-frequency cooker which has not been used in the past can be used and the degree of freedom of the installation place is increased.

[Effects of the Invention] As described above, according to the present invention, the door of the conventional cooking device is the upper lid that forms the cooking chamber, and the upper lid is detachable from the main body, so that cooking food can be taken in and out easily.

Also, by making the upper lid detachable, the degree of freedom of the installation location of the high-frequency cooker increases, and it becomes possible to provide a convenient cooker.

Further, since three or more safety switches that are operated by the peripheral portion of the circular upper lid are provided, it is possible to give an operation stroke for operating the safety switch to open and close the upper lid. It is possible to effectively prevent the generation of the high frequency even when it is out of the range.
