  Therefore, the air sucked from the front intake port 7b flows to the space passage 90 without always passing around the operation unit 5, so that the operation unit 5 can be kept clean.

  The present embodiment has the above configuration, and the operation thereof will be described below.

  When cooking, the ventilator 200 is driven and exhausted. When the cooking pan 100 is placed on the plate 3 and induction heating is performed, the power is turned on with the power switch 19, and the operation is performed on the upper surface operation unit 9 while confirming the display on the upper surface display unit 10 to set the temperature and heating power. To start heating. When heating is started, the heating coil 11 is controlled by the control circuit 150 to heat the cooking pan 100. Further, the blower fan 12 rotates and sucks cooling air from the rear intake port 7a and the front intake port 7b.

  When the air sucked from the front air inlet 7b passes through the space passage 90 provided under the substrate case 14, the bottom surface 14a of the substrate case 14 whose temperature rise is originally low is cooled and stored in the substrate case 14. The temperature rise of the electronic components of the control circuit 150 is mitigated.

  In addition, the temperature of the air in the kitchen cabinet 1 sucked from the rear intake port 7a is somewhat increased by using the cooking device for a long time. However, the temperature is lowered by mixing with air having a small temperature rise sucked from the front air inlet 7b in the vicinity of the suction portion 12a of the blower fan 12, and air lower than the temperature of the air when staying in the kitchen cabinet 1 is reduced. The blower fan 12 blows air into the substrate case 14 to cool the electronic components, and after cooling the heating coil 11 and the like, the air is exhausted from the exhaust port 8. The exhaust is smoothly exhausted to the ventilator 200 and ventilated by the ventilator 200. In this case, the operation unit 5 is generally used in a closed state. When the oven 4 is used, the operation unit 5 is generally used in an open state.

  With respect to the right exhaust port 8a, the cooling air flowing under the plate portion 51 passes through the gap 54, passes over the front side 14h (gap 54) of the second water receiving portion 14c, and passes through the second water receiving portion 14c. Enter inside and pass through the partition wall 52. Then, the air enters the exhaust pocket A53 from the front side 53a of the exhaust pocket A53 inserted into the first water receiving portion 14m, and is exhausted from the exhaust port 8a via the exhaust pocket A53.

  As for the left exhaust port 8b, the exhaust flowing from the lower side of the main body 2 flows without being obstructed by the flow of the cooling air of the heating coil 11, so that the main body 2 can be cooled, and the cooling air of the heating coil 11 is The heating coil 11 is cooled without returning into the main body 2.

  As described above, according to the present embodiment, as a main example of the water entering from the exhaust port 8a, for example, it is considered that the water is blown during cooking. In this way, when water blown down during cooking enters from the exhaust port 8a, it passes through the bottom surface 53b of the exhaust pocket A53, enters the first water receiving portion 14m of the substrate case 14, and passes through the drainage channel 14f on the side surface 14d. The water level does not flow out to the bottom surface 2a of the main body 2 and reach the second water receiving portion 14c.

  In addition, when the entire amount of water in the pan placed on the plate unit 51 (the amount of water that makes miso soup for about four family members) overflows into the plate unit 51, the water spreads to the plate unit 51, and a part of the water Water enters from the exhaust port 8a, passes through the bottom surface 53b of the exhaust pocket A53, enters the first water receiving portion 14m of the substrate case 14, and flows out from the drainage channel 14f on the side surface 14d to the main body 2 bottom surface 2a. When the amount of inflow from the exhaust port 8a is larger than the amount of discharge from the drainage channel 14f, water accumulates in the first water receiving portion 14m and the water level rises. And if it raises to the bottom 14j of the 2nd water receiving part 14c, water will also flow in into the 2nd water receiving part 14c from the partition wall 52, and the main body from the right drainage channel 14g provided in the bottom 14j of the 2nd water receiving part 14c. 2 Flows out to the bottom surface 2a.

  When the water level reaches the bottom 14j of the second water receiving portion 14c, the bottom area of the water receiving portion 14z increases from the opening area of the exhaust port 8a, so that the rise in the water level slows down, and the drainage channels 14e also have two locations and the amount of water discharged As the water level increases, the rise in water level will further slow down. As a result, water does not overflow from the water receiving portion 14z, and water can be prevented from entering the substrate side.

  Further, the exhaust pocket A53 is provided with a hole 53e in the bottom surface 53b, so that even if cooking scraps such as rice and vegetables enter, it is held in the exhaust pocket A53 separately from water. It can be taken out and cleaned, and does not obstruct the flow of the exhaust port 8a.

  Further, the water receiving part 14z is soiled mainly on the first water receiving part 14m side into which the simmered broth generated in normal cooking enters, and it is normal that water reaches the second water receiving part 14c. Since it is not a direction, it does not get dirty, and cleaning is very easy because it is only necessary to clean the first water receiving portion 14m side.

  Since the second water receiving portion 14c does not need to be cleaned, it can be provided on the main body 2 side where it cannot be put into the hand, and the area of the bottom of the water receiving portion 14z where water is accumulated is larger than the opening area of the exhaust port 8a. It becomes possible to do.

  Further, since the bottom 14j of the second water receiving portion 14c is inclined toward the first water receiving portion 14m, the water at the bottom 14j of the second water receiving portion 14c easily flows toward the first water receiving portion 14m. Therefore, the dirt of the bottom 14j of the second water receiving portion 14c is eliminated.

  Next, the flow of exhaust from the left exhaust port 8b1 will be described. The cooling air of the heating coil 11 that flows substantially parallel to the plate portion 51 from the front side to the rear side of the main body 2 is detachably provided at the left exhaust port 8b1 from the opening 57t of the front surface 57n of the exhaust pocket B57, and the exhaust pocket B57. It enters the front room 57e, hits the partition wall 57h of the exhaust pocket B57, is guided upward without flowing through the left and right side surfaces 57c and the bottom surface 57g to the left and right, and is exhausted upward from the upper opening 57d through the left exhaust port 8b1. The

  Therefore, the exhaust gas flowing through the control circuit 150 in the main body 2 and flowing almost directly from the lower side of the main body 2 to the left exhaust port 8b1 enters from the hole 57k in the bottom surface 57j of the rear chamber 57f of the exhaust pocket B57, The room 57f is guided upward by surrounding walls such as the partition wall 57h, the rear surface 57b, and the side surface 57c, and is exhausted upward from the upper opening 57d through the left exhaust port 8b1.

  Exhaust air flowing from the lower side of the main body 2 flows without being obstructed by the flow of cooling air from the heating coil 11 because the air path is divided by the front chamber 57e and the rear chamber 57f by the partition wall 57h. The heating coil 11 can be cooled without cooling air from the heating coil 11 returning into the main body 2.

  If there is no partition wall 57h and the front room 57e and the rear room 57f are one room, the flow of the exhaust discharged from the opening 57t is obstructed and the exhaust discharged from the hole 57 is suppressed and cooling can be performed. The problem which disappears occurs.

  Therefore, according to the present embodiment, even when a large amount of water enters from the exhaust port, it is possible to prevent the entered water from flowing out to the substrate.
