(Flow of cooling air)
4 and 5 schematically illustrate the flow of cooling air in the induction heating cooker according to Embodiment 1 of the present invention. FIG. 4 is a sectional view in side view, and FIG. ) Is a cross-sectional view at a position close to the bottom surface viewed from the top surface, and FIG. 5A is a perspective view (corresponding to a cross-sectional view at a position close to the top surface) viewed from the top surface. In addition, the arrow shown in figure shows the wind flow made into an average, Comprising: Actually, there exists a bias or disorder in a flow. Moreover, the same code | symbol is attached | subjected to this same part as FIGS. 1-3, and one part description is abbreviate | omitted.

  4 and 5, when the heating operation is started by the instruction from the operation control unit 8, the induction heating cooker 100 generates a considerable amount of heat due to switching loss and other losses in the circuits constituting the heating control unit 7. To do. The induction heating coil 5 is supplied with a high-frequency current by the heating control unit 7 and induction-heats a cooking container such as a pan placed on the top plate 2. The induction heating coil 5 also has its own resistance component and the like. It generates heat under the influence of.

(Wind flow in the left first cooling means and the right first cooling means)
For example, when heating information for energizing both the left induction heating coil 5a and the right induction heating coil 5b is input, the left induction heating coil 5a and the left heating control unit 7a, and the right induction heating coil 5b and the right heating control unit 7b. The left first cooling means 10a and the right first cooling means 10b are operated. When only one of the left induction heating coil 5a or the right induction heating coil 5b is energized, the left first fan 12a or the right first fan 12b is activated, but the fan operation is performed on the left and right sides. It is not necessarily linked with heating.

The air flow in the left first cooling means and the right first cooling means is substantially J-shaped in a side view. In other words, the outside air flowing in from the main body inlet 4 forms a wind flow W11 toward the rear surface in the first duct suction portion 11 disposed near the bottom surface of the main body 1. And the direction of a flow is changed in the 1st duct connection part 13, it becomes the wind flow W13, and also the wind flow W14 toward the front surface 1f is formed in a 1st duct cooling part.
And since the 1st duct exhaust port 15 opened in the center side of the left-right direction of the main body 1 is formed in the termination | terminus part (equivalent to the lower part of the coil base 6) of the 1st duct cooling part 14, left 1st The wind flows W15a and W15b that have flowed into the main body 1 from the 1 duct exhaust port 15a and the right first duct exhaust port 15b become wind flows W16a and W16b that flow toward the rear surface while colliding with each other at substantially the center. And it exhausts out of the main body 1 from the main body exhaust port 17 formed near the rear surface of the top plate 2.

(Wind flow in the second cooling means)
On the other hand, there are no parts that make up the operation control unit 8 that generate a large amount of heat. However, if the mounted display unit (such as a liquid crystal panel) or a control microcomputer is exposed to a high-temperature atmosphere, its operation May affect normal operation and prevent normal operation.
In the case of the induction heating cooker 100, the operation control from the heated air that has flowed into the main body 1 due to heat generated by the induction heating coil 5 through heat transfer through the top plate 2 or after the induction heating coil 5 has been cooled. Since the operation control unit 8 becomes high temperature due to heat transfer through the unit holding member 9, the operation control unit 8 needs to be cooled in order to ensure normal operation.

Part of the outside air flowing into the left first duct suction part 11a is sucked by the left second fan 22a and becomes a wind flow W21a flowing into the left second duct suction part 21a, and then enters the second duct cooling part 23. Inflow. And in the 2nd duct cooling part 23, the substantially horizontal wind flow W23a which goes to the center of the left-right direction is formed. Eventually, the second duct exhaust port 24 becomes the wind flow W24, flows out into the main body 1 and mixes with the wind flows W15a and W15b or the wind flows W16a and W16b, and is exhausted from the main body exhaust port 17 to the outside of the main body 1. Is done.
Similarly, after a part of the outside air flowing into the right first duct suction part 11b is sucked into the right second fan 22b and becomes a wind flow W21b flowing into the right second duct suction part 21b, the second duct cooling is performed. Flows into the section 23. And in the 2nd duct cooling part 23, the substantially horizontal wind flow W23b which goes to the center of the left-right direction is formed, and eventually flows out into the inside of the main body 1 from the 2nd duct exhaust port 24, and wind flow W15a, W15b. Or it mixes with wind flow W16a and W16b, and is exhausted out of the main body 1 from the main body exhaust port 17. FIG.

As described above, since the heat generation amount of the operation control unit 8 is relatively small, both the left second fan 22a and the right second fan 22b are measured while measuring the temperature of the operation control unit 8 depending on the necessity of cooling. Or you may make it carry out control which starts or stops one side.
Moreover, although the above demonstrated the case where the heating information which supplies with electricity to both the left induction heating coil 5a and the right induction heating coil 5b was input, it supplies with electricity to one of the left induction heating coil 5a or the right induction heating coil 5b. Even when the heating information to be input is input, in principle, both the left second fan 22a and the right second fan 22b are operated. However, the temperature of the operation control unit 8 is measured and the cooling is required. Accordingly, it is possible to control to start or stop both or one of the left second fan 22a and the right second fan 22b. At this time, since there is no ejector effect in the first duct suction part 11 on the side of the first fan 12 that is stopped, the operation of the second fan 22 on the side of the first fan 12 that is stopped contributes to energy saving. .

As described above, the induction heating cooker 100 in which the pair of induction heating coils 5 is installed is illustrated as the first embodiment, but the present invention is not limited to this, and the induction heating coil 5 is one. Or three or more units may be used.
For example, when there is one induction heating coil 5, one of the left first cooling means or the right first cooling means is installed.
For example, when there are three induction heating coils 5, three first cooling means corresponding to each are installed. Then, one second cooling means communicating with the first duct suction portions of the three first cooling means is installed, or one unit communicating with the first duct suction portions of the two first cooling means, respectively. The second cooling means of the eyes and the second second cooling means communicating with the first duct suction part of the remaining one first cooling means may be installed.

(effect)
As described above, the induction heating cooker 100 includes the induction heating coil 5 and the heating control unit 7 that generate a relatively large amount of heat after taking outside air (cooling air) from the main body inlet 4 into the first duct suction unit 11. In order to divide the outside air for cooling and the outside air for cooling the operation control unit 8 that generates a small amount of heat, a second duct suction unit 21 that branches upstream of the first duct suction unit 11 is provided. For this reason, the operation control unit 8 can be cooled by outside air (low temperature outside air) taken in from the main body inlet 4 without using high temperature air after cooling the induction heating coil 5 and the like. Therefore, the operation control unit 8 can be efficiently cooled.

  Further, a part of the second duct suction part and the second duct cooling part are integrally formed by the operation control part holding member 9, and the operation control part holding member 9 is held so as to be in close contact with the top plate 2. Therefore, the high-temperature air after cooling the induction heating coil 5 and the heating control unit 7 is prevented from entering the second duct cooling unit 23 (containing the operation control unit 8). Therefore, the operation control unit 8 is not exposed to the high-temperature air that has cooled the induction heating coil 5, and the temperature increase of the operation control unit 8 can be suppressed.

Further, the induction heating coil 5 having a relatively large amount of heat generation, the first fan 12 that cools the heating control unit 7, and the second fan 22 that cools the operation control unit 8 having a relatively small amount of heat generation are separately provided. Since it is configured, it becomes possible to make the fan capacities of the respective capacities as required. For this reason, since it is not necessary to install a fan with excessive capacity, the induction heating cooker 100 can be reduced in size and cost.
Moreover, since the left first fan 12a and the left second fan 22a corresponding to the left induction heating coil 5a and the right first fan 12b and the right second fan 22b corresponding to the right induction heating coil 5b are provided, respectively. In addition, fan driving according to heating, such as one-side operation or both-operation of the induction heating coil 5, can be performed, and power saving can be achieved.

  In addition, the air after the induction heating coil 5 and the heating control unit 7 are cooled (high temperature rise) and the temperature after the operation control unit 8 is cooled are relatively low (low temperature rise). Since the air is mixed inside the main body 1 and exhausted outside the main body 1, the former is mixed with the latter, so that the exhaust discharged outside the main body 1 Since the temperature can be lowered, the temperature rise around the induction heating cooker 100 can be reduced.

[Embodiment 2: Induction heating cooker]
6 to 8 schematically illustrate the induction heating cooker according to the second embodiment of the present invention, and FIG. 6 is a system kitchen together with an internal configuration diagram showing the internal configuration from the side. FIG. 7 is a perspective view seen from the top surface. FIG. 8 is a cross-sectional view in side view for schematically explaining the flow of cooling air. In addition, the same code | symbol is attached | subjected to the part which is the same as that of Embodiment 1, or an equivalent part, and a part of description is abbreviate | omitted.

6-8, the induction heating cooking appliance 200 is provided with the 2nd duct notch part 25 (in FIG. 7, the case of three places is illustrated) in a part of front surface 9f of the operation control holding member 9. In FIG. The main body front surface exhaust port 18 is provided at the position of the front surface 1f of the main body 1 corresponding to the position of the second duct notch 25, and is different from the induction heating cooker 100 (Embodiment 1). The point is the same.
Therefore, in the induction heating cooker 200, a part of the air after cooling the operation control unit 8 passes through the second duct notch 25 and the main body front exhaust port 18 and exhausts outside from the front surface 1 f of the main body 1. The wind flow W25 is formed. Since other wind flows are the same as those in the first embodiment, description thereof is omitted.

Therefore, the induction heating cooker 200 is configured to exhaust a part of the air having a relatively low temperature (low temperature rise) after cooling the operation control unit 8 directly out of the main body 1. Since the relatively low temperature air exhausted from the front exhaust port 18 of the main body is blown to the countertop 30 when it is incorporated into the system kitchen, the temperature rise of the countertop 30 can be suppressed. .
In particular, when the roaster 3 is used at the same time, the temperature of the countertop 30 also rises due to the rise in the temperature around the roaster 3, so the effect becomes remarkable.

[Embodiment 3: Induction heating cooker]
FIG. 9 schematically illustrates an induction heating cooker according to Embodiment 3 of the present invention, and is a side view when incorporated in a system kitchen together with an internal configuration diagram shown so that the internal configuration can be seen from the side surface.

Therefore, the roaster heating control unit 7r is effectively cooled by the outside air sucked by the left first fan 12a, and the roaster heating control unit 7r is housed in the left first duct suction unit 11a, whereby the main body 1 The degree of freedom of the arrangement of the members inside is increased, and it becomes possible to effectively use the space, downsize the main body, or to design a more suitable air path.
In addition, since the calorific value of the roaster heating control unit 7r is relatively small, this arrangement does not hinder the cooling of the left induction heating coil 5a and the left heating control unit 7a arranged in the left first duct cooling unit 14a. .

[Embodiment 4: Induction heating cooker]
FIG. 10 schematically illustrates the induction heating cooker according to the fourth embodiment of the present invention, and the side surface when incorporated in the system kitchen together with the internal configuration diagram shown so that the internal configuration can be seen from the side surface. FIG. In addition, the same code | symbol is attached | subjected to the part which is the same as that of Embodiment 2, or an equivalent part, and one part description is abbreviate | omitted.
In FIG. 10, the induction heating cooker 400 is replaced with or added to the electric heater type heating port 5h installed in the induction heating cooker 200 (same as the induction heating cooker 100). A central induction heating coil 5c is installed near the rear surface in the center of the direction, and a central heating control unit 7c for supplying a high-frequency current to the central induction heating coil 5c is connected to the left first duct suction unit 11a (the right first duct suction unit 11b). It is different from the induction heating cooker 200 (Embodiment 2) in that it may be disposed), and the other points are the same.

Accordingly, the central heating control unit 7c is effectively cooled by the outside air sucked by the left first fan 12a, and the central heating control unit 7c is housed in the left first duct suction unit 11a. The degree of freedom of the arrangement of the members inside is increased, and it becomes possible to effectively use the space, downsize the main body, or to design a more suitable air path.
Since the heat generation amount of the central heating control unit 7c is smaller than that of the left heating control unit 7a and the like, the left induction heating coil 5a and the left heating control unit 7a arranged in the left first duct cooling unit 14a by this arrangement. There will be no hindrance to cooling.

  As mentioned above, since the induction heating cooker of this invention can cool the operation control part arrange | positioned ahead in a main body efficiently, it can utilize widely as various induction heating cookers for household use and business. it can.
