  The heating chamber 6 includes an upper heater 15 and a lower heater 16 to form a heating device. A grill 17 is provided between the upper heater 15 and the lower heater 16 so as to be detachable immediately above the lower heater 16. The water tray 18 has a structure in which the grill 17 is placed and filled with water during cooking to prevent the heat of the lower heater 16 from heating the lower part of the heating chamber 6.

  A substantially L-shaped exhaust port 19 with one end communicating with the interior of the heating chamber 6 is provided at the center of the uppermost innermost portion of the heating chamber 6, and the other end is disposed at the same location as the cooling air exhaust port 28 of the cooker body 1. And communicate with the outside. The connecting portion between the heating chamber 6 and the exhaust port 19 is fixed by welding or caulking, and is subjected to wrinkling. By this dredging, the connection between the heating chamber 6 and the exhaust port 19 maintains airtightness, thereby preventing the exhaust from leaking.

  A temperature sensor 29 is provided on the side surface of the exhaust port 19. The temperature sensor 29 detects the temperature of air heated in the heating chamber 6 or generated smoke when it is exhausted from the exhaust port 19, and controls the upper heater 15 and the lower heater 16 connected to the control circuit 5. To do.

  An opening 20 is provided on the front surface of the heating chamber 6, and an object to be cooked 21 such as fish is taken in and out. The opening 20 is substantially closed by a heating chamber door 22 provided integrally with the front surface of the heating chamber 6. The heating chamber door 22 is provided with a water tray 18 and slides in the heating chamber 6 in conjunction with attachment and detachment. The heating chamber door 22 is provided with a handle 23, which is used when the heating chamber door 22 is opened and closed.

  Inside the heating chamber door 22, that is, on the heating chamber 6 side, a seal packing 24 formed of fluorine rubber, hydrogen nitrile rubber or the like is provided. The seal packing 24 has a U-shape that is cut downward and opened substantially downward. Naturally, the seal packing 24 moves together with the heating chamber door 22 when sliding with the water tray 18 when the heating chamber door 22 is opened and closed.

  On the outer periphery of the heating chamber 6, a heat insulating material 30 formed of glass fiber or the like covers the side surface and the bottom surface, and also covers the top surface.

The upper and lower outer shape members 31 and 32 are provided with the mounting flange 10.

  The electrical connection between the heating chamber 6 and the cooking device body 1 is performed by connecting a connector 26 provided in the heating chamber 6 to a connection portion (not shown) of the cooking device body 1.

  The top frame 27 provided on the outer periphery of the top plate 2 is formed of a steel plate or a stainless steel plate and is attached to the top plate 2 in a watertight manner. And the exhaust port 28 of the cooking appliance main body 1 is provided in the back part of this top frame 27, and is provided.

  Next, the operation | movement and effect | action are demonstrated below about the heating cooker comprised as mentioned above.

  A fish that is to be cooked 21 is placed on the grill 17 in the heating chamber 6. The water tray 18 is filled with water, and the upper heater 15 and the lower heater 16 are energized for cooking. The cooking is automatically completed by controlling the energization of the upper heater 15 and the lower heater 16 by the control circuit 5 while detecting the temperature by the temperature sensor 29.

  During cooking in the heating chamber 6, when cooking such as boiling water or fried food with the heating coil 3, power is supplied to the heating coil 3 by the control circuit 5, the control circuit 5 and the heating coil 3 generate heat, and cooling is performed. The device 7 is driven. Further, since the amount of heat generated in the control circuit 5 varies depending on the power supplied to the heating coil 3, the number of revolutions of the cooling device 7 is changed depending on the power consumption, the temperature of the power electronics element of the control circuit 5 is measured, and the cooling device 7 is controlled to reduce the noise of the cooling device 7 during cooking.

  In order to keep the rotation speed of the cooling device 7 constant, it is necessary to set the rotation speed large in order to ensure a sufficient air volume for cooling the control circuit 5 and the heating coil 3 even at the maximum power consumption. However, on the other hand, since the noise of the cooling device 7 during cooking must be reduced to provide a comfortable cooking environment, it is necessary to control the rotational speed of the cooling device 7.

  If the rotation speed of the cooling device 7 is changed, air will be blown into the cooker body 1 and the internal atmospheric pressure will rise. A part of this pressure enters the interior of the heating chamber 6 through the gaps between the components and cools the interior of the heating chamber 6. As a result, the temperature of the object to be cooked 21 decreases and an error occurs in the measured value of the temperature sensor 29. In particular, in the automatic cooking mode, it is conceivable that the baking condition changes, but the heating chamber 6 is independent from the cooker body 1 and is detachably attached to the cooker body 1 from the outside. The cooling air from the cooling device 7 is not affected.

  On the other hand, the inside of the heating chamber 6 rises to about 300 degrees during heating. However, since the exhaust port 19 is located above the heating chamber 6, hot air is discharged from the exhaust port 19 due to the chimney effect of the hot air in the heating chamber 6. While entraining smoke etc. emitted from the object to be cooked 21, the air is heated during this time to become hot air, and the exhaust port 19 above the rear of the heating chamber 6 is raised and discharged outward.

  Furthermore, it is generally the heating cabinet 6 that begins to break down first in the cooker body 1. If the inside of the heating cabinet 6 becomes dirty, it is cleaned, but if the damage is severe over time, the heating cabinet 6 Need to be replaced. In order to disassemble the heating chamber 6, the cooking device body 1 is taken out from the accommodation hole 13 of the kitchen 12, the mounting screw 11 is removed, and the mounting flange 10 of the heating chamber 6 is removed from the cooking device body 1. The connector 26 is detached from the connection portion (not shown) and separated from the cooker body 1.

  Thus, the heating chamber 6 can be separated without disassembling the inside of the cooker body 1. Moreover, since the heating chamber door 22 is provided in the heating chamber 6, it can be attached to and detached from the heating chamber 6, and can be exchanged as a unit together with the heating chamber 6, so that cooking with good serviceability is possible. Can be provided.

  In this embodiment, the upper heater 15 and the lower heater 16 are electrically heated, but the effect is the same even when a heat source such as gas is used.

  As described above, the heating cooker according to the present invention does not affect the heating chamber due to the cooling air filled in the cooking appliance body, and can be easily maintained when necessary, so that the cooking device is not limited to a roaster. The present invention can also be applied to uses such as a microwave oven and electric ovens.
