Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a heating cooker in which a high-frequency heating device (so-called microwave oven) and a toaster oven are arranged in two stages, upper and lower, inside a housing.

[Conventional technology]

In addition to the function of a microwave oven, in which high-frequency radio waves are supplied to the inside of the heating chamber and the food in the heating chamber is dielectrically heated and cooked using these high-frequency waves, a heating heater is installed in the same heating chamber, and this heater 2. Description of the Related Art Composite heating cookers (so-called "oven ranges") that also have the function of an oven to heat and cook food inside are known.

[Problem that the invention attempts to solve]

However, in the conventional microwave oven as mentioned above, the oven function and range function are combined in one heating cabinet, so it is necessary to take measures against high frequency and radio wave leakage of the heater in the heating cabinet and its accessories. At the same time, it was necessary to take measures against the high temperature of the heating chamber, which caused the problem of complicating the structure.

Further, in conventional microwave ovens, the internal space of the heating chamber is large, so that they are not suitable for baking foods such as bread.

In addition, when cooking frozen food, it is first thawed using the function of a microwave oven.
At this time, the temperature of the food to be cooked becomes close to 0°C. Next, the oven function is switched to cook the thawed food, but at this time, the temperature of the food may exceed 100°C. In this way, the temperature inside the refrigerator, which was initially low, rises. In particular, when this frozen food is thawed and heated multiple times, the temperature inside the heating chamber rises and falls due to repeated freezing and heating, which results in extremely poor thermal efficiency and takes a long time to cook. There is a problem.

For example, when cooking frozen gratin, it is necessary to first defrost it using the microwave function at a low temperature, then heat it to a high temperature using the oven function and bake it.This results in a high thermal efficiency as the interior of the refrigerator is repeatedly cooled and heated. It's bad. In addition, since the oven function and range function are combined in one housing, it has a spacious interior that can accommodate relatively large pots and the like, so you can use the interior to bake bread such as toast. is too wide, making it difficult to bake bread.

This invention was made to solve this problem, and the purpose is to provide a compact heating cooker with simple measures against heat.

[Means for solving problems]

The heating cooker according to this invention has a high-frequency heating chamber to which high-frequency radio waves are supplied inside, disposed in the lower part of the housing, and a heater heating chamber, in which a heating heater is installed, arranged in the upper part of the housing, The door of the heater heating storage is a downward-opening door, and the door of the high-frequency heating storage is a door that opens on either the left or right side, and the high-frequency radio wave generator is installed in the housing behind the heater heating storage. It is equipped with parts that generate high heat.

[Effect]

In this invention, the food to be cooked can be temporarily placed on the open bottom-opening door of the heater heating cabinet at the top of the housing, making it easy to take food in and out of the heater heating cabinet located at a high position. Further, even if the bottom-opening door of the heater storage is opened, the side-opening door of the high-frequency heating storage can be opened and closed without touching the door, and burns caused by the hot door of the heater storage can be prevented. Furthermore, since the heater heating chamber having a smaller depth dimension than the high frequency heating chamber is disposed above the high frequency heating chamber, high heat generating components can be disposed using the space created behind the heater heating chamber.

〔Example〕

This invention will be explained below based on the illustrated embodiments.
Fig. 1 shows the external appearance of the heating cooker (for example, a heating cooker named "oven toaster range") according to this invention, Fig. 2 shows the state with the door open, and Fig. 3 shows the heating cooker according to the invention. The outline of each warehouse is shown in a sectional view taken along the line - in the figure. In the figure,
Reference numeral 1 denotes a rectangular parallelepiped-shaped housing of the heating cooker, and 2 is a high-frequency heating chamber (so-called range room) disposed in the lower part of the housing 1 and to which high-frequency radio waves are supplied. The high-frequency heating chamber 2 cooks food by dielectrically heating the food using high-frequency waves, has a function of storing food and heating it with high-frequency waves, and is configured so that high-frequency waves do not leak to the outside. Reference numeral 3 denotes a door that covers the opening for entering and exiting cooked food in the high-frequency heating chamber 2 so as to be openable and closable. 4 is a handle provided on the side of this door 3,
By pulling this handle 4, the door 3 can be opened to the side (arrow A in the figure). Reference numeral 5 denotes a heater heating chamber (so-called oven chamber) which is disposed in the upper part of the inside of the housing 1 and has a heater installed therein, and has the function of heating and cooking food stored inside with the heater. , the depth dimension is smaller than that of the high-frequency heating chamber 2. 6 is heater heating chamber 5
The opening/closing door is opened downward by pulling the handle 7 provided on one side of the upper part of the door 6 (arrow B in the figure). 8 is a toilet that is pulled out at the same time as the door 6 is opened, and 9 is bread as a food on the toilet 8. Reference numeral 10 is a saucer provided at the bottom of the high-frequency heating chamber 2, and 11 is a panel provided with operation buttons 11a and 11b for the heater heating chamber and the high-frequency heating chamber, respectively. Reference numeral 12 denotes a partition wall that partitions the inside of the casing 1 into upper and lower parts.

The heating cooker of this invention configured as described above uses the heater heating chamber (oven chamber) 5 when baking bread such as toast, rice cakes, etc., and on the other hand, it uses the heater heating chamber (oven chamber) 5 when baking bread such as toast, rice cakes, etc. In the case of cooking, the high frequency heating chamber (range chamber) 2 is used, and can be used depending on the purpose of cooking the food, and it is also possible to operate the oven and range at the same time. It's getting old. Furthermore, by making the door 6 of the oven compartment 5 open downwardly and the door 3 of the range compartment 2 open sideways, even when the door 6 of the oven compartment 5 is open, the door 3 of the range compartment 2 can be opened. Even if the door 3 is opened, the handle 4 of the door 3 is located at a distance from the door 6 of the oven chamber 5, so that the user does not accidentally touch the heated door 6, thereby preventing burns.

By the way, although the above embodiment shows the case where the oven chamber 5 and the range chamber 2 are partitioned by the partition wall 12, it is also possible to arrange the oven chamber 5 and the range chamber 2 independently without providing the partition wall 12. It is also possible to do so.

Next, the internal structure of this heating cooker will be explained based on FIGS. 4 to 7. Note that the oven chamber 5 mentioned above is not shown in FIG. In each figure, 20 is a transformer for supplying high voltage to the magnetron 21 that oscillates high frequency, 22 is a capacitor,
These transformer 20, magnetron 21, and capacitor 22 constitute part of a high-frequency radio wave generator for supplying high-frequency radio waves to the inside of the range chamber 2, and are electrical components that generate particularly high heat. 23
is a fan attached to the upper part of the rear of the housing 1, which takes in outside air from above the housing 1, cools the high heat generating parts 20 and 21 with this air, and then sends a portion of this air to both sides and the rear. It is designed to be discharged from the outside of the housing. Further, the remaining warmed air (usually about 100° C.) is supplied into the microwave chamber 2, and has the purpose of removing fog inside the microwave chamber 2 and warming the microwave chamber 2. Reference numeral 24 denotes a waveguide to which the magnetron 21 is attached with a space around it, and which guides the high frequency radio waves generated by the magnetron 21 to the range room 2. The waveguide 24 is attached to a support plate 25 provided on the partition wall 12. There is. The transformer 20 is attached to the casing 1 with a space provided around and below it by a support (not shown). Since the transformer 20 is particularly heavy compared to other parts, the support for the transformer 20 is provided separately from the partition wall 12 in the housing 1.
is fixed. The space is provided around the magnetron 21 and transformer 20 in order to sufficiently dissipate the heat generated by these electrical components. Reference numeral 26 denotes a connection board for wiring connections that is attached in the front-rear direction inside the casing 1 at the bottom of the panel 11. In this figure, the transformer 20 and the magnetron 21 are arranged behind the oven chamber 5 and inside the housing 1, and the capacitor 22 is placed in the oven chamber 5 inside the housing 1.
The case is shown when it is attached to one side of the rear.

By the way, as for the temperature of each component, for example, the temperature of the transformer 20 rises to 150°C, the magnetron 21 rises to 200°C, and the temperature of the capacitor 22 rises to about 50°C. In addition, when there is no food to cook inside the oven chamber 5, the center of the oven chamber is
Temperatures can reach up to 400℃ (MAX 480℃).

As described above, one housing is divided into two storage compartments, upper and lower, with the upper compartment serving as the oven compartment 5 and the lower compartment serving as the range compartment 2. With this feature, you can use the oven and range depending on the purpose of cooking.
And you can run the oven and range at the same time. For this reason, thermal efficiency is improved compared to conventional systems in which both an oven and a range are used in one storage room, and there is no need for high frequency countermeasures such as heaters and countermeasures for radio wave leakage. Furthermore, when separate cooking devices are used for an oven and a range, the space is narrower and the device can be made more compact, easier to handle, and less expensive.

In addition, in conventional so-called "microwave ovens" and "microwave ovens," high heat generating parts such as the transformer 20 and magnetron 21 are stored in a space inside the rear housing of the panel 11, and are housed with heat insulating material. Strict heat insulation measures were taken, and as a result, the width of the housing was large. However, in the heating cooker according to this invention, the space created at the rear of the upper oven chamber 5 can be used to store high heat generating parts. Since they can be assembled in the upper part of the casing 1, heat countermeasures can be simplified, and the width of the casing 1 can also be reduced, making it possible to make the cooking device as a whole more compact. For example, the width of panel 11 is one-third of the conventional width.
It is possible to make it as small as possible.

Furthermore, since the heavy transformer 20 and magnetron 21 are disposed approximately at the center of the rear upper part of the housing 1, the overall weight balance of the heating cooker is better than that of the conventional one.

[Effect of idea]

As explained above, this idea is based on the fact that the door of the heater heating compartment is a downward-opening door, and the door of the high-frequency heating compartment is a door that opens from either the left or right side. It becomes easy to take in and take out the food to be cooked, the door of the high-frequency heating chamber can be opened and closed without touching the open door of the heater heating chamber, and burns caused by the hot door of the heater heating chamber can be prevented. Furthermore, since the high heat generating parts of the high frequency radio wave generator are placed inside the housing behind the heater heating chamber, the heater heating chamber which generates high heat and the high heat generating parts mentioned above can be placed together in the upper part of the housing. This has the effect of making heat countermeasures easier and making it more compact.
