Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a built-in and stationary heating cooker having an induction heating unit in a general household.

[0002]

2. Description of the Related Art It is well known that a cooking device provided with an induction heating unit has a very high thermal efficiency and is safe compared to a gas cooking device, but the internal configuration is complicated and the number of parts is small. Cooling was necessary to prevent the temperature from rising.

Therefore, in a conventional cooking device having an induction heating unit, as shown in FIG. 6, a grill heating unit 51 is disposed on the left side of a body 50 in a built-in type, and a left control unit is disposed above the grill heating unit 51. Section 53, and a left induction heating device 57
The left exhaust port 60 is arranged on the left front part, and the left intake port 62 is arranged on the left rear part, so that a left cooling is provided near the left intake port 62 so as to create a series of cooling air flows. A fan 55 is provided. Further, a grill exhaust duct 63 for exhausting hot air, smoke, and the like inside the refrigerator when the grill heating unit 51 is heated is disposed on the rear upper surface. Similarly, vessel 50
A right control unit 52, a right induction heating device 56, a right intake port 61, a right exhaust port 59, and a right cooling fan 54 are respectively disposed on the right side of the apparatus. Further, a radiant heater 58 is disposed substantially at the center rear of the body 50.

[0004] The container body 50 configured as described above is fitted and fixed on the upper surface to the frame 64 to which the plate 65 is fixed. Here, the left cooling fan 55 rotates, and outside air enters through the left intake port 62 through the ventilation port 66, and cools the grill section heating device 51, the left control unit 53, the left induction heating device 57, and the radiant heater 58, Air is exhausted from the left exhaust port 60. Similarly, when the right cooling fan 54 rotates, outside air enters from the right intake port 61 through the ventilation port 66, cools the right control unit 52, the right induction heating device 56, and the radiant heater 58, and is exhausted from the right exhaust port 59. Configuration.

[0005] Further, the stationary type has a 180 mm module height restriction, and has a configuration similar to the above-mentioned built-in type but without a grill portion heating device. The configuration was such that only one means could be provided.

[0006]

The heating cooker provided with the induction heating unit configured as described above has the following problems. That is, in the built-in type or the stationary type configuration as shown in FIG. 6, the respective configurations for cooling the left side surface and the right side surface are different, and the cooling balance is poor and it is difficult to efficiently cool. The effect had to be improved. In addition, since the noise oscillated from the right induction heating device and the left induction heating device directly affects the respective control devices, it is likely to cause a malfunction of the control function. Also, the inside atmosphere is exhausted toward the person who uses it during cooking, giving discomfort,
Since the intake port and the grill exhaust duct are adjacent to each other, there is a problem that oil smoke and hot air are easily sucked into the inside.

Further, in the stationary type, another heating device or the like is disposed above the grill portion heating device under the restriction of the 180 mm module height size, so that the inside height of the grill portion heating device is reduced. I can not secure a large,
Only one heating means using a sheathed heater as a heat source can be provided on one side, and when cooking fish etc., it becomes cumbersome and inconvenient to turn over and cook again, resulting in a difference in cooking performance such as uneven grilling. There is a problem that it is easy to cause.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a grill heating unit disposed substantially at the center of a body, and a plurality of upper heating units arranged substantially symmetrically with respect to the grill heating unit. By arranging the device, control device, cooling fan, intake port and exhaust port, the right and left sides of the body can be cooled efficiently in a well-balanced manner, and the temperature of each component rises And the grille heating device covered with metal acts as a barrier to reduce the noise oscillating from the upper heating device in a well-balanced manner.

Further, in the stationary heating cooker, only the grill part heating device is disposed substantially at the center of the body,
Since the inside height of the grill heating device can be sufficiently secured against the 180 mm module height dimensional restriction, two heating means can be provided on the upper surface portion and the lower surface portion of the grill heating device. Another object of the present invention is to provide a heating cooker that does not need to be turned upside down when cooking fish or the like, and can provide grilling performance without uneven grilling even if anyone cooks.
