Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a cooking device that heats food using microwaves and electric heat.

2. Description of the Related Art Conventional heating devices of this type include toaster microwave ovens and oven microwave ovens. These devices are collectively called complex devices that combine a microwave oven with other additional functions.

There are two types of these devices: one in which microwaves and electric heat are supplied to one heating chamber, and the other in which each heating source is provided with an independent heating chamber. A type that shares one heating chamber is ideal for continuous cooking using electric heating and microwave cooking. However, it is not possible to proceed with different types of cooking at the same time, and when using electric heating, the temperature inside the heating chamber becomes high, so if you subsequently use microwave cooking, it is necessary to lower the temperature inside the heating chamber. There are cases.

On the other hand, a type having a heating chamber independent of the heating source has the advantage of being capable of simultaneous cooking, but requires a large installation space and is not convenient to configure as a single device.

Problems to be Solved by the Invention The ultimate goal of compounding is to be able to technically achieve a compounded device without impairing its original functionality. That is, the ultimate challenge in achieving this in combining microwave heating and electric heating is to be able to perform simultaneous cooking and, if possible, to configure the device with one heating chamber. Since this latter problem is physically impossible, the challenge is how to achieve it.

Based on the above, the ultimate challenges in combining electric heating and microwave heating can be summarized as follows.

Issue (]) It is possible to proceed with simultaneous heating.

Section B (2) The device is compact and requires little installation space.

The present invention has been made to solve such conventional problems, and an object of the present invention is to provide a novel heating cooker that is capable of performing electric heating and microwave heating simultaneously and that is a compact composite device.

Means for Solving the Problems In order to solve the above problems, the basic structure of the cooking device of the present invention includes a first heating chamber in which an object to be heated is stored and a microwave is supplied, and one wall of the heating chamber. An opening/closing door forming a
It consists of a second heating chamber provided in the opening/closing door, and a heating means for heating the second heating chamber. Furthermore, the heating means is provided to heat the first heating chamber and the second heating chamber.

Function According to the above-described configuration of the present invention, the first heating chamber is mainly used for microwave cooking, and the second heating chamber that is electrically heated is used for heating bread.

Furthermore, for example, pizza, kasuri, doria, gratin, madeleine, etc. can be heated in the first heating chamber by combining microwave heating and electric heating.

Therefore, for example, toast and coffee can be heated at the same time, reducing cooking time, and toast and miso soup can be heated at the same time, making it possible to accommodate individual meals at home, such as those who prefer Western or Japanese food. .

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

In Figures 1 to 3, 1 is the first heating chamber to which microwave power is supplied, 2 is the first opening/closing door forming one wall of the first heating chamber, and 3 is the first opening/closing door. a second heating chamber provided; 4 a second door that can be opened and closed together with the second heating chamber; 5 heating means 20 that is provided within the second door and heats the second heating chamber; Reference numeral 6 denotes a first heating means provided between the first heating chamber 1 and the second heating chamber 3. 7 is a microwave generator such as a magnetron; 8 is a waveguide for transmitting microwaves generated by the microwave generator to the first heating chamber; 9 is the microwave generator 7; accelerating means 5.6
This is a drive power supply section that drives the oscillator and controls its operation.

Reference numeral 10 denotes a microwave leakage device that prevents the microwaves supplied to the first heating chamber from leaking through the gap between the opening and closing door and the main body 11 when the first opening and closing door 2 is closed. The structure having a prevention function, 12, is a device main body support.

Reference numeral 4 denotes a second opening/closing door, which, including the second heating chamber 3 and second heating means, is constructed so that it can be opened and closed further apart from the first opening/closing door, as shown in FIG. . Further, as shown in Fig. 3, the first opening/closing door is configured to be able to be opened and closed so that the object to be heated can be taken in and out of the first heating chamber which is integrally provided in the main body with the second opening/closing door. There is. The surface 13 of the first opening/closing door facing the first heating chamber is provided with a large group of punches with an aperture ratio within a range where microwaves do not leak, while the surface facing the second heating chamber is It is a structure that efficiently radiates the heat generated by the heating means 6 to the second heating chamber and acts as a storage guide for the object to be heated stored in the second heating chamber.

With the above configuration, the first heating chamber has the same function as a heating chamber used in a conventional microwave oven, and uses the radiant heat from the first heating means to create a heating chamber that can be used in a conventional toaster microwave oven or oven microwave oven. It has the same effect as the heating chamber used in In addition, the second heating chamber has the same function as a conventional toaster, and the second
As shown in the figure, when used with the second opening/closing door open, it has the same effect as a conventional electric heater.

FIG. 4 shows another embodiment of the present invention, which differs from FIG. 1 in the structure of the first heating chamber. That is, the first heating chamber 14 in FIG. The rear upper wall surface 16 of the heating chamber is formed into an arc shape depending on the relative positional relationship with the means. Therefore, the curvature of this arc is determined so that the radiant heat of the first heating means is most effectively transmitted to the entire bottom surface of the first heating chamber.

With this configuration, the radiant heat from the first heating means to the object to be heated (the figure shows a pizza) shown in FIG. 4 is efficiently heated through the heat transfer path shown by the broken line in the figure. .

Note that the first and second heating means are so-called heaters, and are composed of an electric heater, a halogen heater, a sheathed heater, or the like. Further, the operation of the heating means and the microwave are controlled independently, and they may be operated simultaneously.

Furthermore, the operations of the first heating means and the second heating means may be made independent.

Further, although the opening/closing door is shown in the embodiment as having a slightly inclined structure, this inclined structure is not limited to the embodiment of the present invention, and a surface structure with a curvature may be used.

Effects of the Invention As described above, the heating cooker of the present invention provides the following effects.

(1) By providing a second heating chamber within the opening/closing door, it is possible to provide a compact and convenient device that can simultaneously perform electric heating cooking and microwave cooking.

(2) By having a double opening/closing door configuration, the second heating chamber can be used independently when the first heating chamber is in use, and the second heating chamber can be used when the second opening/closing door is closed. A new heating space can be created that can be used both in closed and open states.
