[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an electric heating cooker such as a microwave oven, an electric oven and a microwave oven.

[0002]

[Problems to be solved by conventional techniques and devices]

 In this type of conventional electric heating cooker, there is only one heating chamber for one exterior body, and at a time, it can heat only the amount (or number) that can be placed on the mounting table (turntable) in the heating chamber. Did not. Therefore, in order to heat a large number of people or different types of foods or the like (or pieces) that cannot be processed in a single operation with a conventional electric heating cooker, it is necessary to process the foods in multiple operations. In addition to the time required, there was a time difference in cooking, and what was heated first during eating could cool down. In particular, restaurants may order a large number of dishes to be heated by an electric heating cooker at the same time, but if there is too much time difference between the dishes to be served to customers, slow customers may complain. If you wait until all the food items are ready and try to serve them at the same time, the previously cooked (heated) food will cool down.

[0003] If a plurality of electric heating cookers of this type are prepared, a plurality of foods can be individually heated at the same time, but the purchase cost is high and the installation space for the plurality of foods is required. Is required.

[0004] In view of the above problems, an object of the present invention is to provide an electric heating cooker that can perform the function of a plurality of cookers even if it is a single cooker.

[0005]

[Means for Solving the Problems]

 The present invention has the following configuration as means for solving the above-mentioned problem. Note that the present invention is directed to an electric heating cooker such as a microwave oven, an electric oven, and a microwave oven.

[0006] The electric heating cooker of the present invention is provided with a plurality of upper and lower divided heating chambers in a single exterior body and heating means capable of individually heating each heating chamber. I have.

Each of the heating chambers can be divided into upper and lower sections by partitioning the exterior body with a horizontal partition wall. The number of heating chambers is not particularly limited, but is suitably about 2 to 4. Further, a turntable may be provided in each heating chamber.

[0008] The heating means is provided separately for each heating chamber, and can heat each of the heating chambers independently.

The heating means of each heating chamber employs at least one of a magnetron (which oscillates high frequency) and an electric heater. That is, in the case where only the magnetron is used as the heating means, the heating chamber functions as a microwave oven. In the case where only the electric heater is used as the heating means, the heating chamber functions as an electric oven. In the case of employing both, the heating chamber functions as a microwave oven. Further, each heating chamber may have only the same function (microwave ovens, electric ovens, and microwave ovens), or may have different functions (for example, a combination of a microwave oven and an electric oven). Each heating means in each heating chamber can be turned on / off simultaneously or independently by an operation unit provided on the front surface of the exterior body.

[0010] Each heating chamber may be opened and closed simultaneously by a single door, or an individual door may be provided for each heating chamber so as to be individually opened and closed. When all heating chambers are opened and closed simultaneously with a single door, there is an advantage that the door only needs to be opened and closed once, but if there is a time lag between heating in each heating chamber, the door is opened until the slower heating ends. There is a disadvantage that it cannot be opened.On the other hand, if each heating chamber can be opened and closed individually with individual doors, it has the advantage that it can be opened and closed for each heating chamber, but has the disadvantage that the number of times the doors must be opened and closed increases. Yes, each has advantages and disadvantages.

[0011]

[Effect of the invention]

 The electric heating cooker of the present invention has the following effects. (1) Since a plurality of heating chambers are provided in a single exterior body, and each of the heating chambers can be individually heated by the heating means, a large amount (a large number) of foods or different kinds of foods can be heated and cooked at the same time. (2) Since each heating chamber is provided with a single exterior body divided into upper and lower sections, even if there are a plurality of heating chambers that can be heated substantially individually, the whole The installation space (especially the occupied floor area) can be reduced. (3) Since multiple heating chambers are provided in a single exterior body, costs can be reduced as compared to manufacturing multiple electric heating cookers individually, and the functions of multiple It can be provided at a low price while ensuring.

[Embodiment of the invention]

 The electric heating cooker of the present invention will be described with reference to FIGS. 1 to 3. FIGS. 1 and 2 show a first embodiment, and FIG. 3 shows a second embodiment. The electric cooking device of the present application is intended for a microwave oven, an electric oven, a microwave oven, and the like.

The electric heating cooker according to the first embodiment shown in FIGS. 1 and 2 has two upper and lower heating chambers 3 and 4 formed in a single exterior body 1, and each heating chamber 3 and 4 has Each heating unit 5 is provided, and each of the heating chambers 3 and 4 can be opened and closed by a single (single) door 8.

Each of the heating chambers 3 and 4 is vertically partitioned by partitioning the interior of the exterior body 1 with a horizontal partition wall 2. The height of each of the heating chambers 3 and 4 may be reduced so as not to impair the function, and the overall height of the exterior body 1 may be reduced. In this embodiment, the upper and lower heating chambers 3 and 4 are formed. However, in other embodiments, three or more heating chambers can be formed in a single exterior body 1 ( Even in that case, up to about 4 rooms is appropriate.)

[0015] Turntables 11, 11 are provided on the bottom surfaces of the heating chambers 3, 4, respectively. Each of the turntables 11 is driven by a motor (not shown).

The heating means 5 is provided individually for each of the heating chambers 3 and 4 so that the heating chambers 3 and 4 can be independently heated. As the heating means 5, 5 for each of the heating chambers 3, 4, at least one of a magnetron 6 (see FIG. 2) that oscillates a high frequency and electric heaters 7A and 7B is adopted. The heating chambers 3 and 4 use a magnetron 6 and electric heaters (upper electric heater 7A and lower electric heater 7B), respectively. That is, in this embodiment, each of the heating chambers 3 and 4 has both functions of a microwave oven by the magnetron 6 and an electric oven function by the electric heaters 7A and 7B (oven range function). In this embodiment, the electric heaters 7A and 7B are provided above and below the heating chambers 3 and 4, however, in other embodiments, only the upper electric heater 7A or only the lower electric heater 7B may be used.

As described above, if the upper and lower heating chambers 3 and 4 are provided with a microwave oven function, both the heating chambers 3 and 4 are simultaneously used in the form of the same type of function (microwave ovens or electric ovens). Alternatively, each of the heating chambers 3 and 4 can be used simultaneously in the form of different functions (one is an electronic range and the other is an electric oven). When the amount of processed food is small, only one of the heating chambers 3 and 4 can be used.

In another embodiment, the heating means 5 of each of the heating chambers 3 and 4 employs only the magnetron 6 (only the microwave oven function), or employs only the electric heaters 7A and 7B (electric power). Oven function only). The heating chambers 3 and 4 may have the same function (microwave ovens and electric ovens) or may have different functions (combination of microwave oven and electric oven).

The heating units 5 and 5 of the heating chambers 3 and 4 can be turned on / off simultaneously or independently by operating units 12 and 12 provided on the front surface of the exterior body 1. Each of the operation units 12 and 21 can be provided with various operation switches for each cooking in addition to basic operation units such as a selection switch of an electronic range and an electric oven and a timer.

In the first embodiment shown in FIGS. 1 and 2, each of the heating chambers 3 and 4 can be simultaneously opened and closed by a single (single) door 8. When the heating chambers 3 and 4 are simultaneously opened and closed by a single door 8 as described above, there is an advantage that the door only needs to be opened and closed once, but if there is a heating time difference between the heating chambers 3 and 4. The disadvantage is that the door cannot be opened until the slower heating is completed.

In the electric heating cooker according to the second embodiment shown in FIG. 3, the heating chambers 3 and 4 can be individually opened and closed by individual doors 9 and 10. The main body side (outer body 1, heating chambers 3, 4, heating means 5, 5, operating units 12, 12, etc.) of the electric heating cooker of the second embodiment is the same as that of the first embodiment. This is exactly the same, and the description of the main body side in the second embodiment uses that of the first embodiment.

In the second embodiment, since the heating chambers 3 and 4 can be individually opened and closed by the individual doors 9 and 10, there is an advantage that each heating chamber 3 and 4 can be opened and closed individually. On the other hand, there is a disadvantage that the number of times of opening and closing the door increases.

In the electric heating cooker according to each of the first and second embodiments, a plurality of (two) heating chambers 3 and 4 are provided in a single exterior body 1. 4 can be individually heated by the heating means 5 and 5, respectively, so that a large number (a large number) of foods or different kinds of foods can be cooked simultaneously by a single electric heating cooker. In addition, when a plurality of heating chambers 3 and 4 are provided in a single exterior body 1 as described above, even if there are a plurality of heating chambers that can be heated substantially individually, the entire number of heating chambers is reduced for the number of heating chambers. It can be made compact, and the installation space (particularly the occupied floor area) can be reduced. Further, in the case where a plurality of heating chambers 3 and 4 are provided in a single exterior body 1, the cost can be reduced as compared with the case where a plurality of electric heating cookers are individually manufactured, and a plurality of functions are secured. And can be provided at low cost.
