In this case, the opening area of the main blowout outlet 25 is set so that it may become larger than the auxiliary blowout outlet 28 of the right part side in the heating chamber 12 back surface.

Moreover, the suction port 29 is formed in the part corresponding to the center part of the fan 18 in the back surface of the heating chamber 12. As shown in FIG. Each of these ejection openings 25, 26, 27, 28 and the suction opening 29 are each formed by a plurality of small holes (punching holes).

In this case, the rotation direction of the fan 18 is set to be counterclockwise (see arrow C in FIG. 1) when viewed from the front. In the casing 17, the shielding plate 30 constituting the shielding portion is fixed to a portion corresponding to the bottom edge of the lower outlet port 26 as shown in FIG. 5.

The plate support part 32 for installing the angled plate 31 is provided in the substantially center part of the upper and lower sides of the left and right sides of the heating chamber 12, and the angled plate 31 is made to be accessible in the heating chamber 12. It is made to be accepted. The bottom of the heating chamber 12 is provided with a rotating mesh 34 which is rotationally driven by the motor 33 constituting the driving means, and on this rotating mesh 34 is made of ceramic, in this case magnetic Dish 35 is made to be installed. The lower heater 36 which consists of a surface heater is provided in the lower part of the heating chamber 12, in this case, the lower surface of the bottom part of the inner box 13. As shown in FIG.

As for the angled dish 31, the width length of the left-right direction is set to be substantially the same as the width length in the heating chamber 12, as shown in FIG. 1, and the length of the front-back direction is the heating chamber 12 as shown in FIG. It is set to be substantially equal to the length in the front-back direction in parentheses. As shown in FIG. 1, when the angled dish 31 and the round dish 35 are accommodated, the upper portions of the main outlet 25, the upper auxiliary outlet 27, the auxiliary outlet 28, and the suction port 29 are angled. It is located above the plate 31, and the lower outlet 26 and the lower part of the suction port 29 are located between the angled plate 31 and the round plate 35.

As shown in FIG. 4, the recessed part 37 dug upward is formed in the ceiling part of the heating chamber 12. As shown in FIG. Although not shown, a magnetron is provided on the outer surface side of the heating chamber 12, and microwaves generated by the magnetron are supplied into the heating chamber 12 when the stove is cooked. In addition, the hot air supply device 16 is covered from the rear by the rear cover 38 (see FIG. 3).

Next, the operation of the present embodiment will be described.

First, the case where both the angled dish 31 and the round dish 35 are accommodated and cooked in the heating chamber 12 is demonstrated. In this case, the fan 23 is driven by the motor 23 of the hot air supply device 16, while the heater 19 is energized, and the round plate 35 is rotated by the motor 33, and at the same time, The heater 36 is energized.

Among these, based on the blowing action of the fan 18 of the hot air supply device 16, the air in the heating chamber 12 is sucked into the casing 17 at the inlet port 29 and heated by the heater 19 at the same time. It is taken out in the heating chamber 12 by each of these blowout ports 25-28.

Since the rotation direction of the fan 18 is a counterclockwise direction (arrow C direction), the hot air blown out from the main air outlet 25 in the upper part of the center part in the left-right direction of the rear side of the heating chamber 12 is shown in FIG. As indicated by the arrow D, the casing 17 flows forward from the left side (opposite to the suction port 29) opposite to the biased side and downwards, and then on the door 12 and the angled plate 31. Along the right side and then into the casing 17 at the inlet 29.

At this time, since the hot air blown out from the main outlet 25 flows almost entirely in the heating chamber 12 from the left side to the right side, it is placed on the angled plate 31. The cooked object (not shown) is heated very uniformly. In addition, since the hot air facing downward reaches the angled dish 31 well, the workpiece can be heated well.

In addition, the hot air blown out from the upper auxiliary outlet 27 located above the rear surface of the heating chamber 12 causes the recess 37 of the ceiling portion of the heating chamber 12 to be removed as indicated by arrows E in FIGS. 4 and 7. Along the left front side, and after changing direction in the door 14, it flows backward along the angled dish 31. As shown in FIG.

At this time, the recess 37 is formed in the ceiling of the heating chamber 12, and the hot air blown out of the upper auxiliary outlet 27 is separated from the suction port 29 so as to flow along the lower surface of the recess 37. do. For this reason, the hot air blown out of the upper auxiliary blow-out port 27 flows directly into the inlet port 29, so that a so-called short circuit can be prevented, and the hot air can be guided well to the front part of the heating chamber 12. can do.

In addition, since the planar shape of the angular dish 31 is formed in substantially the same size as the plane shape of the heating chamber 12, the hot air flowing to the front part of the heating chamber 12 does not turn downward of the angular dish 31. , The upper surface portion of the angled plate 31 flows. For this reason, the to-be-processed object on the angled dish 31 can be heated more efficiently by the hot air. In addition, since many installation areas for raising the workpieces of the angled dish 31 can be secured, many workpieces can be cooked at once.

Moreover, the hot air blown out from the auxiliary blower outlet 28 in the upper right part of the rear side of the heating chamber 12 flows mainly in the right side of the heating chamber 12. As shown in FIG. In this case, the heating by the hot air taken out from the main outlet 25 and the upper auxiliary outlet 27 tends to be weaker than the other portions of the right side on the angled dish 31, but at the auxiliary outlet 28 By taking out the hot air, the heating of the right part can be supplemented, and the to-be-cooked object can be heated more uniformly.

On the other hand, the hot air blown out from the lower outlet port 26 in the lower part of the center portion in the left and right direction of the rear side of the heating chamber 12 mainly flows downward from the center of the heating chamber 12 toward the front and bottom, and the direction of the door 12 is changed. After the change, it flows toward the suction port 29. In this case, in the casing 17, since the shielding plate 30 is provided in a portion corresponding to the bottom edge of the lower outlet port 26, the hot air by the fan 18 in the casing 17 is shielded. As the hot air is blown out from the lower outlet port 26 toward the heating chamber 12 as it touches the plate 30, the amount of hot air blown out of the lower outlet port 26 into the heating chamber 12 can be very large. have.

At this time, the workpiece on the round plate 35 is heated by the hot air blown out from the lower outlet port 26. In this case, the hot air is easy to be biased to almost the center portion of the round plate 35, but since the round plate 35 rotates, the cooked material on the round plate 35 is heated very uniformly. Moreover, since the to-be-cooked object on the round plate 35 is heated by the lower heater 36 from below, the lack of heating by hot air can be compensated for by the heating of the lower heater 36, and the to-be-cooked object further It can be cooked efficiently. Moreover, the to-be-cooked object on the angled dish 31 is heated also by the hot air blown out from the lower blower outlet 236 also under.

In addition, by being able to cook using not only one angled dish 31 but also the round dish 35, the quantity which can be cooked at once can be made as much as the round dish 35. In addition, since the round plate 35 is made of ceramic, the round dish 35 can be used not only at the time of cooking by the hot air but also at the time of stove cooking, and the accessory can be effectively used.

On the other hand, in the case of accommodating and cooking only one angled dish 31 in the heating chamber 12, the rotating net 34 may be rotated or may not be made, and the lower heater 36 may be energized or not. .

According to the first embodiment described above, the following effects can be obtained.

In the hot air supply device 16, the width length A1 in the left and right directions of the casing 17 is set smaller than the width length A2 in the left and right directions of the heating chamber 12, so that the casing 17 is further extended. The hot air supply device 16 can be made compact, and the cost can be reduced.

The casing 17 is biased to the right side with respect to the heating chamber 12 so that the main blowout outlet 25 of the hot air to the heating chamber 12 is positioned at the uppermost portion of the center in the left and right directions of the heating chamber 12. At the same time, by setting the rotational direction of the fan 18 to be counterclockwise, the hot air blown out of the main chamber 25 into the heating chamber 12 is biased in the heating chamber 12. It flows forward with the left side opposite to, and then flows to the right. Therefore, since the hot air flows over the whole of the heating chamber 12, even when the angled dish 31 is accommodated and cooked in the heating chamber 12, the cooking material placed on the angled dish 31 is very uniform. It can be heated easily.

The hot air blown out from the main blower outlet 25, the upper auxiliary blower outlet 27, and the upper auxiliary blower outlet 28 is circulated on the upper side of the angled dish 31, and is hardly distributed below the angled dish 31. Therefore, the to-be-cooked object on the angled dish 31 can be heated more efficiently by such a hot air.

When cooking by placing the round plate 35 on the rotating net 34, the round plate 35 is heated by the hot air at the lower outlet 26 and heating by the lower heater 36 while rotating the round plate 35. The to-be-cooked product can be heated and cooked very uniformly and efficiently.

Since the arc-shaped portions 19a and 19b are formed at two places of the heater 19, the auxiliary outlet port 28 and the lower outlet port 26 (sub-outlet) are formed outside the arc-shaped portions 19a and 19b. A large space can be secured. As a result, although the casing 17 is downsized, the range in which hot air is blown out can be secured widely, and the nonuniform heating can be further reduced.

Fig. 8 shows a second embodiment of the present invention, which differs from the above-described first embodiment in the following points.

That is, in the first embodiment, the shielding portion 40 is integrally provided in the casing 17 in place of the shielding plate 30. In such a configuration, there is an advantage that the number of parts can be reduced, and the cost can be reduced accordingly.

9 and 10 show a third embodiment of the present invention, which is different from the first embodiment described above in the following points.

That is, the arc shape part 41 is formed in one place of the lower right among four corner parts of the casing 17. As shown in FIG. In addition, in the lower right part of the back surface of the heating chamber 12, it is located in the part which becomes just above the round dish 35, and the lower auxiliary blower outlet 42 is formed.

By such a configuration, the flow of hot air flowing in the casing 17 is smooth in the arc-shaped portion 41, and the flow resistance of the hot air is reduced in the portion, and the casing 17 becomes hot. Can be prevented as much as possible. Moreover, since the lower auxiliary blower outlet 42 is formed, the hot air is blown out into the heating chamber 12 from here, especially when cooking using the round dish 35, the round dish 35 also by the hot wind. The processed product of the phase can be heated, and the heating efficiency can be further improved.

On the other hand, the heater 19 is fixed in the casing 17 as follows. Both terminals 43 of the heater 19 are located at the upper left of the casing 17. In the outer circumferential portion of the terminal 43, which is one end of the heater 19, a fixing shade 44 is provided in a fixed state so as to be orthogonal to the direction in which the heater 19 extends. The left side wall 17a of the casing 17 which the fixing awning 44 abuts becomes a slope 44 whose rear end is inclined to the right, and the heater 19 is inserted into the slope 45. The through hole 45a is formed. Moreover, in the casing 17, the heater fixing mechanism 47 which has the U-shaped support part 46 is fixed to the right side opposite to the fixing shade part 44. As shown in FIG.

The heater 19 accommodates most of the inside of the casing 17 while the terminal 43 protrudes outward from the casing 17, and at the same time, the right side of the heater 19 supports the heater fixing mechanism 47. It is in the state inserted in (46). The heater 19 is inclined in the direction of the arrow E by the slope 45 by applying the fixing shade 44 to the slope 45 from the inside of the casing 17. The right side of) is fixed to the support part 46 in the state joined by pressing in the arrow (E) direction.

By attaching the heater 19 in such a configuration, even when vibration occurs in the motor 23 for rotating the fan 18, the heater 19 can be prevented from vibrating as much as possible, and further, the heater 19 ) And the surrounding portion thereof can prevent the occurrence of so-called vibration sound.

The present invention is not limited to each of the above embodiments, but can be modified or expanded as follows.

The hot air supply device 16 may be disposed to be biased to the left side with respect to the heating chamber 12. In this case, the rotation direction of the fan 18 is set clockwise from the front.

The auxiliary outlet port 28 on the upper right side may be provided as necessary, and may not be provided. When the auxiliary outlet port 28 is not provided, the opening area of the auxiliary outlet port on the side of the heating chamber 12 is zero.

The round plate 35 may be made of glass.
