Abstract

High frequency microwaves and stem are supplied to a heating chamber (20) disposed inside the disclosed high frequency cooking device (1). On the floor of the heating chamber is formed a funnel-shaped slope (28), at the bottom of which is formed a condensate drain (27). A rotation shaft (31d) for transmitting rotation to a turn table (30) passes through the condensate drain. A cup-shaped support base (33) supporting a motor (32) for rotating the rotation shaft catches the condensate flowing out of the condensate drain. A drain pipe (36) forming part of the drain path (37) is connected to a drain (35) of the support base. A U-shaped bend (36a) formed in the drain pipe constitutes a water-sealing unit (39) where condensate accumulates.

Claims

1. A microwave cooking device which is adapted to be capable of supplying steam into a heating chamber inside the device, wherein

a condensate drain port is formed in a bottom wall of the heating chamber, and

a water-seal portion which keeps condensate is formed in a drain passage which starts at the condensate drain port.

2. The microwave cooking device according to claim 1, wherein

a funnel-shaped slope is formed in the bottom wall of the heating chamber, and

the condensate drain port is arranged in a lowest part of the slope.

3. The microwave cooking device according to claim 1, wherein

a turntable on which an object to be heated is placed is arranged inside the heating chamber, and

a rotary shaft which transmits rotation to the turntable penetrates the condensate drain port.

4. The microwave cooking device according to claim 3, wherein

a cup-shaped support base is fixed on an outer face of the bottom wall of the heating chamber,

the support base supports a motor which gives rotation to the rotary shaft, and

the support base collects condensate that flows out through the condensate drain port.

5. The microwave cooking device according to claim 4, wherein

a drain pipe which constitutes part of the drain passage is connected to a drain port which is formed in the support base, and

a bend which is formed as a part of the drain pipe constitutes the water-seal portion.

6. The microwave cooking device according to claim 1, wherein

a drain pan is arranged where the drain passage ends.

7. The microwave cooking device according to claim 2, wherein

a drain pan is arranged where the drain passage ends.

8. The microwave cooking device according to claim 3, wherein

a drain pan is arranged where the drain passage ends.

9. The microwave cooking device according to claim 4, wherein

a drain pan is arranged where the drain passage ends.

10. The microwave cooking device according to claim 5, wherein

a drain pan is arranged where the drain passage ends.
