  As shown in FIG. 1, an electromagnetic induction heating cooker 100 according to the first embodiment includes a main body 1 configured in a box shape, and cooking utensils such as a pan and a frying pan provided on the top surface of the main body 1 (not shown). ). And induction heating coils 3a and 3b for induction heating the cooking utensils are arranged on the left and right below the top plate 2 as two left and right mouths. Further, a single radiant heater 4 is disposed on the back side of the central portion below the top plate 2. The number of induction heating coils is not limited to the above, and at least one induction heating coil may be used. In some cases, the electromagnetic induction heating cooker may be configured with only an induction heating coil, omitting the radiant heater.

  In the front part of the top surface of the main body 1, an operation unit 5 provided with a display and switches for representing a cooking menu is arranged. Further, on the front surface of the main body 1, for example, the operation panel unit 6 disposed on the right side is provided with a power switch, induction heating coils 3 a and 3 b, a radiant heater 4, a heating amount adjustment dial for the roaster 7, and the like. The roaster 7 is a cooking chamber used for grilled fish and the like, and is disposed on the left side portion of the main body 1 here, and a roaster case 8 (see FIG. 3) formed in the main body 1 below the induction heating coils 3a and 3b. 4). The roaster 7 is provided with heaters 9 in the upper and lower portions, and is configured such that the tray can be pulled out forward (to the front) of the main body.

  The internal structure of the main body 1 is shown in FIGS. The lower half of the back wall of the main body 1 is formed in a hollow shape, and an air inlet 10 is provided in the hollow portion. And the cooling fan 11 is installed near the inlet 10 inside the main body. The cooling air supplied to the inside of the main body 1 by the cooling fan 11 flows in the direction shown by the arrow in the figure, and the cooling air is finally discharged from the exhaust port 12 (see FIG. 1) provided at the rear of the top surface of the main body 1 Discharged. As described above, the air inlet 10 for taking in the outside air is provided in the recessed portion of the back wall, so that the main body 1 can be installed close to the wall surface of the kitchen, and even in such an installed state, the intake air is sufficient. Can be secured.

  As shown in FIG. 2, the inside of the main body is divided into upper and lower spaces by a partition plate 14, and each space is a storage chamber for control boards 15 and 16. The storage chambers for the control boards 15 and 16 are provided on the right side of the main body 1, that is, on the rear side of the operation panel unit 6. The lower control board 15 is a power supply board, and the upper control board 16 is an IH board. The space between the top plate 2 and the upper surface plate 13 of the main body 1 is a place where the induction heating coils 3 a and 3 b and the coil unit of the radiant heater 4 are installed. Cooling air flows into the installation location of the coil unit from a ventilation port 19 provided in the upper surface plate 13. In addition, each control board 15 and 16 is provided with the cooling fins 17 and 18, respectively, in order to improve cooling efficiency.

  In order to reinforce the left and right side wall plates 1 a and 1 b of the main body 1, as shown in FIGS. 4 and 5, the reinforcing member 20 passes through the space between the operation unit 5 and the roaster case 8 and the side wall plates 1 a and 1 b. It is built in. The reinforcing member 20 is made of a groove member made of metal such as iron or stainless steel and has a U-shaped cross section. And the reinforcement member 20 is attached so that the opening part of a U-shaped cross section may face the induction heating coils 3a and 3b and the coil unit of the radiant heater 4. As shown in FIG. Further, as shown in FIGS. 3 and 4, the upper surface plate 13 of the main body 1 and the upper surface wall of the roaster case 8 are formed so that the opening height is slightly lower in the front portion of the main body 1 than the inner portion. The reinforcing member 20 is installed in the front space.

  Further, an air passage forming member 21 having a U-shaped cross section is provided inside the reinforcing member 20. The air passage forming member 21 is doubled with the reinforcing member 20. The air path forming member 21 may be a metal material, but is preferably a material having a heat insulating property, for example, a heat insulating resin. Alternatively, the air passage forming member 21 may be a film in which the inner surface of the reinforcing member 20 is coated with a heat resistant resin or paint. Further, a resin air direction member 22 is detachably attached to the tip of the air path forming member 21. The air direction member 22 is provided so that the cooling air guided by the air path forming member 21 is directed toward the coil unit of the left induction heating coil 3a. Between the wind direction member 22 and the coil unit of the induction heating coil 3a on the left side, a guide member 23 that guides cooling air is provided. The wind direction member 22 may be formed integrally with the air path forming member 21. However, by changing only the wind direction member 22 by configuring it separately, the specification changes (the size of the induction heating coil 3a on the left side). There is an advantage that it can respond immediately to changes in sheath position.

  Next, the cooling action at the time of cooking by the electromagnetic induction heating cooker 100 will be described. The cooling air is taken into the main body 1 from the air inlet 10 by rotating the cooling fan 11. The cooling air taken into the main body 1 flows in parallel to the upper and lower substrate storage chambers as indicated by arrows in FIG. 2, and the induction heating coils 3a, 3b from the ventilation openings 19 provided in the upper surface plate 13 of the main body 1. And flows into the space where the coil unit of the radiant heater 4 is installed. The cooling air that has flowed into the upper and lower substrate storage chambers cools the control boards 15 and 16 installed in the respective substrate storage chambers and suppresses the temperature rise of the board-mounted components. Next, the cooling air enters the air passage forming member 21 provided in the reinforcing member 20 having a U-shaped cross section, and flows along the air passage forming member 21 (in FIG. 2, the air passage forming member 21 is on the near side). Flow towards). Then, the cooling air flows out from the wind direction member 22 and flows along the guide member 23 toward the left induction heating coil 3a.

  On the other hand, the cooling air that has flowed into the coil unit installation location from the ventilation port 19 cools the coil unit of the induction heating coil 3b on the right side as shown in FIG. The cooling air flows through the substrate housing chambers of the substrates 15 and 16 and flows out of the air direction member 22 to cool the coil unit installation location uniformly. Thereafter, the cooling air is discharged to the outside through an exhaust port 12 provided at the rear of the top surface of the main body 1.

  As described above, according to the first embodiment, the reinforcing member 20 is provided at the front part of the top surface of the main body 1 through the space between the operation unit 5 and the roaster 7 on the left and right side wall plates 1a, At the same time that the left and right side wall plates 1a and 1b are reinforced by being laid on 1b, an air passage forming member 21 is provided inside the reinforcing member 20 to secure a cooling air passage. Therefore, it is possible to make the cross section of the reinforcing member 20 as large as possible by effectively utilizing the narrow space between the operation unit 5 and the roaster 7, and to reinforce the left and right side wall plates 1a and 1b and to secure the air path. Can be achieved at the same time. In addition, since the air passage forming member 21 is formed of a heat insulating material, even if the heat from the roaster 7 is transferred to the reinforcing member 20, it is difficult to transfer heat to the internal air passage forming member 21, so that the efficiency is high. There is an effect that cooling becomes possible. Moreover, the same effect can be obtained by forming the air passage forming member 21 with a heat insulating film obtained by coating the inner surface of the reinforcing member 20 with a heat insulating resin or paint.

  Further, the reinforcing member 20 and the air passage forming member 21 have a U-shaped cross section, and since the opening of the cross section is installed toward the induction heating coils 3a, 3b and the radiant heater 4, The strength for reinforcement can be increased, and the cooling air can be smoothly guided in the longitudinal direction of the air passage forming member 21.

  Further, by providing the wind direction member 22 that allows the cooling air to flow toward the induction heating coil 3a at the tip of the air passage forming member 21, it is possible to direct the cooling air directly to the component (induction heating coil) to be cooled. it can. For this reason, efficient cooling becomes possible.

  In the above embodiment, the kitchen stationary electromagnetic induction heating cooker has been described, but the present invention can also be applied to a kitchen built-in type (built-in type) electromagnetic induction heating cooker.
