Description

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 cooks cooked foods using high frequency waves.

[Prior Art] High-frequency heating devices for heating cooked foods are used as microwave ovens and the like 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. JIl! (4) is a magnetron that generates high-frequency microwaves; (5) is the magnetron (
A waveguide that guides the high frequency waves generated in 4) to the cooking chamber (2), (
6) is an operation panel, (6a) is a start switch that starts the cooking operation, (6b) is a setting switch that sets the operating time, and (7) is a door that seals the inside of the cooking chamber (2).

According to such a conventional cooker, the food is placed on the rotary table (3), the door (7) is closed, and the setting switch (6) is turned on.
b) By pressing the start switch (6a) at a predetermined time, cooking is started. Then,
High frequency waves are generated by the magnetron (4) and are radiated into the cooking chamber (2) via the waveguide (5).

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

[Problems to be Solved by the Invention] By the way, a conventional general high-frequency cooker has a box shape as shown in Fig. 3, and has a door (7) in front of it. 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 high frequency leakage, or necessarily, the door (7) is formed 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 there is a problem in the past that improvements should be made to make it easier to take food in and out. be.

Furthermore, since the conventional high-frequency cooker is a relatively large box as shown in FIG. 3, its installation location is limited to places such as on top of a refrigerator, and its 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 amount of space, and there is a problem that it should have a simple structure.

Therefore, the present applicant is attempting to provide a new type of high-frequency cooker in which the lid and main body can be completely separated, but it is unclear what state the food is in while being cooked with such a cooker. It would be convenient to be able to see inside the cooking chamber where high-frequency waves are trapped.

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

[Means for Solving the Problems] The high-frequency cooker according to the present invention has a top-lid type door for putting in and taking out cooked food, and the top lid is detachably attached to the main body, and forms a cooking chamber that confines high-frequency waves. do. The present invention is characterized in that a discharge tube is disposed within the upper lid without electrical wiring, and the discharge tube is lit using high frequency waves emitted for heating and cooking.

[Function] According to the above structure, when the top lid is opened, it is completely removed from the main body, so the upper part of the main body is wide open, making it easy to take in and out cooked food.

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

A discharge tube is provided inside the top lid, and the discharge tube can be lit by radiating high frequency waves to the discharge tube as well. Therefore, since the inside of the cooking chamber is brightly illuminated, 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, where (10) is the main body, (11) is the case of the main body (10), and (12) is -1, which is a feature of the present invention. (12
) is a food cooking chamber (300) in the form of a truncated cone in the example.
The entire upper fi (12) or only its inner surface is formed of a metal plate to confine high frequencies.

Further, in the embodiment, pores are formed on the wall surface of the entire area of the upper lid (12). (13) is upper i (12) is the main body (10)
The handle f, (14) is for attaching and detaching from the upper fi (12

This discharge tube (14) is attached to the fittings (36a), (36
It is attached in b).

Reference numeral (15) denotes a food processing table that transmits high frequency waves, and is attached through a gasket (16) so as to fit into a groove formed in the support plate (17). Moreover, the support plate (17)
is composed of two metal plates, and these two metal plates form a tubular choke chamber (200) on the outer periphery of two sides 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 operating piece (18a) of the microswitch.
11) is a protector formed integrally with the 1 unit lid (
12) pushes down the actuating piece (18a), thereby making it possible to generate and output high frequency waves.

In addition, (20) is a high-voltage transformer, (21) is a high-voltage capacitor, (22) is a high-frequency oscillator magnetron, (
23) is a radiation fin that diffuses the heat generated in the magnetron (22), and (24) is a radio frequency: ARI! The antenna (25) radiates into the room, and the magnetron (22)
and a cooling fan for cooling the high voltage transformer, etc. (2
6) is a blower motor that drives the cooling fan;
This cooling fan (25) and 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). can be radiated efficiently.

The first characteristic feature of the present invention is that the conventional door for loading and unloading cooked food into and out of the high-frequency cooker is removed! (
12), and this upper lid (12) has a volume to form a cooking chamber (300) for cooking food, and by making this upper lid (12) removable from the main body (10), cooking is possible. It is possible to easily and simply take food into and out of the cooking chamber (300).

Therefore, at least the upper fi (12) is constructed so as to open up a part or all of the space on the top and side surfaces of the cooking device in the conventional cooking device. The structure is such that everything is open.

In addition, in the embodiment, in order to make it easier to remove the top cover (12), the top! (12) The outer circumferential shape is circular. That is, if the outer peripheral shape is a square shape, J[(12)
Since the directionality occurs, the opening of l-1 (12) must be closed in accordance with the shape of the main body (10).

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

In addition, in the example above! (12) was made into a truncated cone,
It may also have a hemispherical shape.

The next characteristic feature of the present invention is 1, 21. In order to brighten the laboratory, the upper lid (10) is separable from the main body (10).
12) into the discharge tube (14) without electrical wiring.
This was done by providing a battery and discharging it at a high frequency.

This discharge tube (12) may be any 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. As shown, the discharge tube (12) is attached to the apex portion within the Lif (12) by a fitting (36).

Furthermore, as shown in Fig. 2, the discharge tube (14) may be attached to the side of the upper lid (12), and the radiation density of the high frequency is determined by considering the radiation distribution of the high frequency when the food is placed a. It is preferable to install it in a high position.

Furthermore, it is necessary to use a discharge tube that discharges at a high frequency of the intensity used for normal cooking, and the location of the discharge tube and its installation must be determined by considering the high frequency density of the location. to be determined.

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 lid (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 circumference is circular, high frequency leakage can be easily prevented.
Furthermore, the design and manufacture of the top cover (12) becomes easier.

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

When heating cooked food, grip the handle (13) and open the top (c12), which releases the microswitch (18) and prohibits the magnetron (22) from operating. Even if you accidentally operate the operating switch of the cooker (not shown), high frequency waves will not be output. When the food is to be cooked, the food must be placed on the food table (15), as described above! (12)
can be completely removed from the main body (10),
Food can be placed on the container.

After placing the cooked food on the food table (15), open the top lid (12).
) is closed as shown, the microswitch (18) is closed and the magnetron (22) is allowed to operate.

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 storage stand (15), so the high-frequency waves are radiated into the cooking chamber formed by the top lid (12), thereby heating the food. Cooking takes place.

The high frequency waves at this time are also 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, top! Since a pore is formed on the wall surface throughout the area (12), the inside of the cooking chamber (300) can be seen through this pore.

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 waves are confined by the upper M (12) made of a metal plate and do not leak out from the side surfaces of the upper cover (12). And -t-i! (12) and the main body (1
At the connection part 0), high frequency waves are shielded by the choke chamber (200), so that good cooking can be performed without leaking high frequency waves to the outside from this connection part.

Furthermore, the present invention is superior! By making (12) detachable from the main body (10), it 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 usually the upper lid (
12) and use the top lid (12) only when using it as a cooking device. Then, when the cooker is not in use, the main body (10) acts as a plate or stand, and when cooking, the upper lid (12)
) can be used to easily heat and cook on the dining table.

In this way, in the present invention, the main body (10) and the top lid (12) can be separated, so the main body (1 (1)
) can be embedded. Therefore,
It has the advantage of allowing the use of high-frequency cookers, which has not been done in the past, and increasing the degree of freedom in installation locations.

The present invention provides a cooker in which the upper lid (12) is completely separated from the main body as described above, in which the discharge tube is connected to the upper lid (12).
There is an advantage in that the cooking room can be brightened without the need for electrical wiring by disposing it inside the room and discharging it at a high frequency.

[Effects of the Invention] As explained above, in this invention, the conventional cooker has an upper lid that forms the cooking chamber, and the upper lid is removable from the main body, making it easy to put in and take out cooked food. Become.

Furthermore, by making the top lid removable, the degree of freedom in installing the high-frequency cooker increases, making it possible to provide a first-of-its-kind cooker.

Since a discharge tube is provided in the upper lid and is lit using high frequency, the cooking chamber can be brightened without electrical wiring.

As a result, the cooking state of the food being cooked can be observed, making it possible to cook with peace of mind.
