DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a high-frequency cooker, and particularly to a structure for a new type of high-frequency cooker, which is used to cook food using high frequency waves.

[Prior Art] High-frequency cookers for heating cooked foods are used as electric ranges in homes or in the kitchens of various restaurants.

FIG. 3 is a diagram showing the schematic configuration of a conventional high-frequency cooker. In the figure, (1) is the main body, (2) is the cooking chamber for storing and cooking food, and (3) is the cooking chamber for storing and cooking the cooked food. (4) is a magnetron that generates high-frequency microwaves; (5) is a waveguide that guides the high-frequency waves generated by the magnetron (4) to the cooking chamber (2); (6) is an operation In the panel, (6a) is a start switch that starts the cooking operation, (6b) is a setting switch that sets the operation time, and (7) is a door that seals the inside of the cooking chamber (2).

According to such a conventional cooker, the cooked food is placed on the rotary table (3), the door (7) is closed, and the setting switch (6) is turned on.
Cooking is started by pressing the start switch (6a) at a predetermined time. Then, a high frequency wave is generated by the magnetron (4), and this high frequency wave is radiated into the cooking chamber (2) via the J9 wave tube (5).

Since the rotary table (3) rotates with the cooked food placed thereon, high frequency waves are evenly radiated to the cooked food, thereby allowing the food to be heated and cooked.

[Problem to be solved by the invention C' This makes it relatively inconvenient to take food in and out.

That is, the cooking chamber (2) is designed to have as small a volume as possible in order to emit high frequency waves or to make the entire cooking device compact. Also,
In order to prevent leakage of high frequency waves, or necessarily, the door (7) is formed so as to open one side of the box.

Therefore, it is relatively troublesome to take food in and out of the small-volume cooking chamber (2) from one side of the box, and the conventional method should be improved to make it easier to take food in and out. There is.

Furthermore, since the conventional high-frequency cooker is a relatively large box like the one shown in Figure 3, there is a problem in that it takes up a relatively large amount of space when not in use, depending on its installation location. , the problem was that it should have a simple configuration.

Therefore, the applicant intends to provide a new type of high-frequency cooker in which the lid and main body can be completely separated. It is necessary to check whether
High frequencies are trapped. If you can see inside the control room, it's Envoy II+.

This invention has been made to solve these problems, and provides a high-frequency cooker that allows easy loading and unloading of cooked food, a high degree of freedom in installation locations, and the ability to observe the inside of the cooking chamber during cooking. The purpose is to provide a high frequency cooker.

[Means for Solving the Problems] The high-frequency YS processor according to the present invention has a main body in which a high-frequency generator is disposed on the back side of a food table, and has an upper lid-type door for loading and unloading cooked food. The two lids are removable from the main body, and the first lid forms a cooking chamber that confines high frequencies. When the upper lid is formed into a substantially hemispherical shape, a discharge tube is arranged inside the apex of the upper lid without electrical wiring, and high frequency waves are radiated into the cooking chamber from the back side of the center of the food table. It is characterized by lighting a discharge tube.

The substantially hemispherical shape includes not only a circular sphere but also an elliptical sphere.

[Function] According to the above configuration, when opening the top cover, the top cover is completely removed from the main body, so the top of the main body is widened (opened), making it easy to take in and out 1. .

Furthermore, since the top lid and the main body are separated, it is also possible to attach only the main body to another element such as a table and use the top lid only when cooking.

The top cover is made into a substantially hemispherical shape, and a discharge tube is provided at the top of the top, and high-frequency waves are radiated to the discharge tube from near the center of the food table, making it possible to light the discharge tube well and easily. can.

Therefore, since the inside of the cooking chamber is brightly illuminated by the discharge tube, the cooking state of the food can be observed.

[Embodiments] Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

FIG. 1 shows the configuration of a high-frequency cooker, in which (10) is the main body, (11) is the case of the main body (10), (12) is the lid which is a feature of the present invention, and 12
) is a food cooking chamber (300) with a substantially hemispherical shape in the example.
The entire upper n (12) or only its inner surface is formed of a metal plate to confine high frequencies.

Further, in the example, pores are formed on the wall surface of the entire area of the upper If (12). (13) -L lid (12)
(14) is a handle for attaching and detaching from LIE (12).
) is a discharge tube that is a feature of the present invention, and
This discharge tube (14) is attached to the inside of the apex of 1Yi (12) using fixtures (36a) and (36b).

Reference numeral (15) is a food mounting table that transmits six frequencies, and is attached through a gasket (16) so as to fit into a groove formed in the support plate (17). In addition, the support plate (17
) was purchased with two metal plates, and these two metal plates form a tubular choke chamber (200) on the outer periphery of the top surface of the main body.
This choke chamber (200) completely shields high frequencies leaking from the joint between the top cover (12) and the main body (10).

(18) is a microswitch, and (19) is a case (19) for protecting the actuating piece (18a) of the microswitch.
11) is a protector formed integrally with
(12) pushes down the actuating piece (18a),
High frequency generation output becomes possible.

Further, (20) is a high voltage transformer, (21) is a high voltage capacitor, and (22) is a magnetron which is a high frequency generator that is a feature of the present invention. Deploy. (23) is a radiation fin that diffuses the heat generated in the magnetron (22); (24) is an antenna that is attached to the tip of the magnetron (22) and radiates high frequency waves into the cooking chamber; (25) is the magnetron (22) and A cooling fan (26) is a blower motor that drives the cooling fan for cooling the high voltage transformer, etc., and the cooling fan (25) and the blower motor (26) constitute a cooling device.

The antenna (14) is provided to properly radiate high frequency waves into the cooking chamber (300).
24) has a disk shape with the outer circumference bent downward, and has a structure to be attached to the coaxial (22a) of the magnetron (22). According to this, the antenna (24) placed at the center of the food table (15) transmits high frequency waves into the cooking chamber (300) without using the conventional waveguide (Fig. 3). It is efficient (can radiate).

The first characteristic feature of the present invention is that the conventional door for taking cooked food in and out of the high-frequency cooker is replaced with a lid (1).
2), and this 1-lid (12) has a volume for forming a cooking chamber (300) for cooking food, and furthermore, by making this upper lid (12) freely removable from the main body (10), 1. It is possible to easily and simply take cooked food into and out of the cooking chamber (300).

So at least above! (12) is a conventional cooker that is configured so that the top surface and part or all of the side surfaces can be opened, and in the embodiment, the top surface and all of the side surfaces are opened. There is.

Further, since the upper lid (12) is approximately hemispherical and has a circular outer circumferential shape, the upper M (12) can be removed more easily. In other words, if the outer circumferential shape is square, the upper M (12) will have no-j orientation, so the main body (
10) While matching the shape of the side -II! The opening in (12) must be closed.

Therefore, if the outer circumferential shape is circular, there is no directionality and the top cover (12) can be opened and closed easily.

The next characteristic feature of the present invention is that the cooking chamber can be separated from the main body (10) in order to make it brighter!
(12) without electrical wiring.
), which can be discharged well and easily at high frequencies.

For this purpose, the upper fi (12) is formed into a substantially hemispherical shape, the discharge tube (14) is placed inside the apex of the upper fi (12), and the magnetron (22) is placed near the center point of the upper lid. The configuration is as follows. That is, the discharge tube (
12) may be a commonly used type, and consists of a glass tube coated with fluorescent paint on the inside, evacuated, and filled with argon gas, neon gas, etc., as shown in Figure 1. , the discharge tube (12) is attached to the apex within the upper lid (12) by a fitting (36).

On the other hand, the magnetron (22) is provided on the main body (10) so as to be located near the center point of the upper lid, and its antenna (24) is attached to the food table (15) as shown in FIG. is arranged so as to face the discharge tube (14) on the back side of the discharge tube (14).

According to this, the high frequency waves are affected by reflection from the inner wall of the spherical LM (12), and the density of the high frequency waves radiated from the antenna (24) becomes relatively high at the apex portion, and the density of the high frequency waves radiated from the antenna (24) becomes relatively high at the top portion.
) can be efficiently discharged. This was determined from the results of an experiment in which the discharge tube (14) was placed in another location and standard cooked food was placed on the food table (15). The upper lid (12) can be used more easily and easily than upper lids of other shapes.
) can be discharged.

The discharge tube (14) does not discharge simply by being exposed to high frequency waves; in order to keep it lit in a stable state, it is necessary to stably supply high frequency waves of a predetermined intensity. (14) and the magnetron (22) must be arranged in an optimal positional relationship. The present invention
In response to such demands, the above-mentioned configuration allows the discharge tube (14) to be maintained in an extremely stable discharge state.

In addition, in the embodiment, since the outer periphery of the cooker is circular, leakage of high frequency waves can be easily prevented. That is, the periphery of the upper M (12) and the choke chamber (200
) If the outer periphery is made into a square shape, gaps are likely to form in the corner-formed portion, making it difficult to prevent high frequency leakage. Therefore, if the outer circumferential shape is circular, leakage of high frequency waves can be easily prevented, and the design and manufacture of the top cover (12) can be simplified.

The embodiment has the above configuration, and its operation will be explained above.

When heating cooked food, hold the handle (13).
-1 (12), which releases the microswitch (18) and prohibits the operation of the magnetron (22). However, high frequencies are never output. When you want to cook, it takes a while to place the food on the food table (15), but the front lid (12) can be completely removed from the main body (10). You can easily put food on it.

After placing the cooked food on the food table (15), place the food on the upper 1f (1
2) as shown in the figure, the micro switch (18)
is closed and operation of the magnetron (22) is allowed. Therefore, when the cooker is activated, the magnetron (22
) operates and high-frequency waves are output from the antenna (24) located on the back side of the center position of the food table (15), so the high-frequency waves are radiated into the cooking chamber formed by the top lid (12). is heated and cooked.

Then, the high frequency waves at this time are well radiated to the discharge tube (14), and the discharge tube (14) is discharged by the high frequency waves and lights up, making it possible to brighten the inside of the cooking chamber (300). In this case, 1. Since pores are formed on the wall surface of the entire area of the lid (12), the cooking chamber (300
) will look inside. In this way, the cooking state of the food being cooked can be observed, and the food can be cooked with peace of mind.

Note that the high frequency is confined by the metal plate 1 (12) and does not leak out from the side surface of the upper fi (12). Since high frequencies are shielded by the choke chamber (200) at the connection between the top 1 (12) and the main body (10), good cooking can be performed without leaking high frequencies to the outside from this connection. can.

Historically, by making the lid (12) detachable from the main body (10), the present invention can be used in the following ways in addition to the conventional usage. That is, the main body (10) is installed so as to be embedded in the center of the dining table, and the upper lid (10) is usually installed.
2) is removed and the 1-lid (12) is used only when used as a cooking device. Then, the tone p
When o: is not used, the main body (10) acts as a nl or stand, and when cooking, the top lid (12) can be used to easily heat and cook on the dining table. can.

In this way, in the present invention, the main body (10) and the top lid (12) can be separated, so the main body (10) can be placed on the cooking table or other places.
It can be provided by embedding it. Therefore, it is possible to use a high-frequency cooker, which has not been done in the past, and there is an advantage that the degree of freedom in the installation location is increased.

The present invention is a cooking device in which the above-mentioned 11 (12) is completely separated from the main body, and the discharge tube is placed on top! (12)
Since the magnetron (22) is arranged at the apex of the main body (10) and at the center of the main body (10), the discharge tube (14) can be discharged well and easily by high frequency. Therefore, there is an advantage that the cooking room can be brightened without electrical wiring.

[Effects of the Invention] As explained above, in this invention, the door of a conventional cooker is used as an upper lid that forms a cooking chamber, and this 1-lid is made detachable from the main body, making it easy to put in and take out cooked food. becomes.

Furthermore, by making the lid removable, the degree of freedom in installing the high-frequency cooker increases, making it possible to provide a cooker that is more convenient.

In addition to installing a discharge tube at the top of the two lids, we also radiated high-frequency waves from the back of the center of the food/food stand, making it possible to light up the discharge tube well and easily. You can brighten up your cooking room without having to do anything. As a result, the cooking state of the food being cooked can be observed, making it possible to cook with peace of mind.
