(Embodiment 1)
1 to 3 show detailed views of the cooking device according to the first embodiment of the present invention.

  1 to 3, a cooker body 12 having a heat source 11, a fan 15 that blows air to a heat generating portion 14 in the cooker body 12, rotates about a rotating shaft provided on a substantially horizontal plane, and is forcibly cooled, The intake port 13 provided on the front or bottom of the outer surface of the outer surface of the cooker main body 12 or both, the fan intake port 17 of the fan 15 on a substantially vertical plane, and air outside the cooker main body 12 is sucked from the intake port 13. A control board 20 that controls the output of the heat source 11 on the downstream side of the cooling air blown substantially rearward by the fan 15, a board case 21 that houses and fixes the board under the control board 20, and opens and closes the front opening. A cooking chamber 22 that has a door 31 and heats an object to be heated housed therein, an exhaust port 10 that is disposed in the upper part or rear part of the outer surface of the outer surface of the cooker body 12 and exhausts cooling air, and a cooker Provided in front of the main body 12 The fan exhaust port 30 provided in the substantially tangential direction on the outer periphery of the fan 15, the cooking cabinet shielding plate 32 above the cooking cabinet 22, the heat source 11 on the cooking cabinet shielding plate 32, and toward the approximate center of the heat source 11. A duct 39 that forms an air passage for blowing air, and that guides the cooling air blown from the fan exhaust port 30 in the substantially tangential direction on the outer periphery of the fan 15 to the duct 39, and the duct 39 separates the cooling air. The air passages for blowing air from the plurality of openings 40 are provided, and the plurality of openings 40 are configured to be blown to the heat source from the oblique direction and the lateral direction, respectively.

  About the path | route structure of the cooling air of the heating cooker comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  In the case of a heating cooker that uses a flame such as a gas as a heat source, an induction heating coil that generates a magnetic field and heats a pan, or a heat source that generates Joule heat by passing an electric current through an electrical resistance The control board that controls the operation of the cooker is heated by the heat generated by the heat source.

  Furthermore, in a heating cooker that heats a pan with an induction heating coil, the induction heating coil and the control board self-heat due to the current flowing on the induction heating coil and the circuit of the internal control board and the electrical resistance of the circuit.

  In order to lower the temperature of the induction heating coil and the components on the control board to below the heat resistant temperature, a forced air cooling type cooling configuration is required in which the air outside the cooker is sucked, the internal components are cooled, and then exhausted.

  Furthermore, since the cooking chamber 22 is a system that cooks an object to be heated by heating a heating member such as a heater inside the cooking chamber 22, the temperature of peripheral members rises. Therefore, it is necessary to guide the cooling air in order to suppress the temperature rise of the peripheral members or the temperature rise of the outer surface of the cooking device main body.

  In the conventional cooking device, the cooling air is directly blown to the heat source 11 on the cooking chamber 22 side.

  However, in the conventional method, the heat around the cooking chamber 22 is transferred to the heat source 11, and it is difficult to determine the direction to the heat source 11 and the members around the heat source 11 and to guide the air well.

Furthermore, as the output of the heat source is increased and the heating power is increased, the heat generation amount of the heat source 11 and the members around the heat source is increased, so that it is necessary to improve the cooling efficiency.

  Therefore, in the present embodiment, a duct that forms an air passage that blows cooling air blown out in a substantially tangential direction on the outer periphery of the fan 15 toward the approximate center of the heat source 11 and the heat source 11 on the cooking cabinet shielding plate 32. 39 having a configuration in which the air is guided and branched to 39 and blown from the plurality of openings 40, and cooling air is blown from the plurality of openings 40 to the heat source 11 from the oblique direction and the horizontal direction, respectively. The cooling air is simultaneously introduced from both the upper surface and the lower surface side of the heat source 11 to the heat source 11 and the heat source 11 peripheral members.

  This prevents the heat source 11 from being warmed by the heat generated by the cooking chamber 22 and simultaneously blows a relatively cool cooling air near the room temperature outside the cooker body 12 sucked by the fan 15 to the heat source 11 directly. Is possible.

  Therefore, it is possible to provide a heating cooker with high product value that is highly reliable with high cooling efficiency, high cooling efficiency of internal components, and high durability. It becomes possible to easily protect the heat source 11 and the members around the heat source 11 from the heat of the cooking chamber 22 and make the component below the heat resistant temperature.

  As a result, the cooling efficiency is increased with a small amount of air, so that the number of rotations of the fan 15 can be reduced, and a heating cooker capable of realizing low-noise and high-efficiency cooling performance can be obtained.

  The members around the heat source 11 are heated by the LED for emitting the light emitting ring for displaying the position of the heat source 11, a control board for mounting the LED, a connector and a lead wire for supplying power to the LED, and the heat source 11. It includes a temperature detecting means for detecting the temperature of the pot and the like, a control board necessary for its control, and a connector and a lead wire for supplying electric power necessary for driving the same, and these can be cooled.

  Furthermore, the temperature rise of the peripheral members of the heat source 11 is restricted, and the problem that the cooking performance is deteriorated because the output of the heat source 11 cannot be sufficiently increased can be solved.

  Further, the fan intake port 17 is not provided in the vicinity of the intake port 13 but is installed at a position different from substantially the same plane, for example, in a substantially vertical plane, thereby forming an intake path from the intake port 13 of the fan 15 to the fan intake port 17. Thus, even if boiled juice or the like that is a cooked product is sucked into the intake port 13, the possibility of reaching the fan intake port 17 immediately and entering the inside of the cooker can be reduced.

  The substantially vertical plane is preferably a plane that is 60 to 120 degrees with respect to a substantially horizontal plane. This is because heat-generating components that require cooling are generally within this range for the cooling fan.

  Due to the positional relationship in which the intake port 13 is provided at the bottom of the cooker main body 12 or the front part in the vicinity thereof, the fan intake port 17 is provided above the intake port 13, and the intake path from the intake port 13 to the fan intake port 17. Inside air flows from below to above.

  Even if boiled soup or the like, which is a cooked product, is sucked from the air inlet 13 from the air inlet 13, there is an effect of reducing the possibility of falling into the inside of the cooker by dropping due to its own weight in the air intake path.

  Furthermore, by making the cross-sectional area of the intake path from the intake port 13 to the fan intake port 17 larger than the opening area of the intake port 13, the flow velocity of the air flowing through the path is reduced, and the weight of boiled juice or the like falls in the intake path Even if boiled soup or the like, which is a cooked product, is sucked from the air intake port 13 through the air intake port 13, the fan air intake port 17 is reached and the possibility of entering the inside of the cooker is reduced.

  After the direction of the wind generated from the fan 15 (impeller) is changed by the fan case 16, the centrifugal fan 15 configured to blow air to the heat generating component on the control board is used to cook the fan intake port 17. Even when the broth of the object enters, the moisture, which is the main component of the broth, is heavier than the air, and is thus blown out of the rotation center of the fan 15 by centrifugal force and adheres to the fan case 16.

  This has the effect of reducing the possibility of moisture adhering directly to the electronic components in the cooking machine. Furthermore, in order to prevent cooking such as boiled juice adhering to the fan case 16 from accumulating, a discharge groove may be provided inside the fan case 16 and discharged outside the cooker body 12.

  The same effect can be obtained by using a multi-blade fan (sirocco fan), a turbo fan, a radial fan, or other centrifugal fans as the centrifugal fan 15. The same effect can be obtained not only in the built-in type cooking device incorporated in the kitchen but also in the stationary type cooking device installed on the table.

As described above, in the present embodiment, the cooling air blown in the substantially tangential direction on the outer periphery of the fan 15 is formed on the cooking cabinet shielding plate 32 toward the heat source 11 and the approximate center of the heat source 11. By having a structure in which the air is guided to the duct 39 to be branched and blown from the plurality of openings 40 and the cooling air is blown from the plurality of openings 40 to the heat source 11 from the oblique direction and the lateral direction, respectively. The cooling air is simultaneously introduced from both the upper surface and the lower surface of the heat source 11 to the heat source 11 and the peripheral members of the heat source 11 to prevent the heat source 11 from being heated by the heat generated by the cooking chamber 22 and at the same time, the cooking sucked by the fan 15 It becomes possible to blow a relatively cool cooling air close to substantially room temperature outside the main body 12 directly to the heat source 11, and to make a cooking device with high commercial value and high durability with high cooling efficiency of internal components. Kill.
Moreover, it becomes a structure which is hard to suck | inhale oil smoke, a vapor | steam, boiled juice which is a cooking product, etc. with air warmed when heating a cooking product from an inlet port. Thereby, it can be set as the heating cooker with high commercial value which is easy to use and excellent in cooling efficiency and rich in reliability.
