However, if the exhaust ports 8a and 8b are always open, oil droplets and water droplets may occur inside the exhaust ports 8a and 8b when oil splashes or spills occur during cooking using the electromagnetic cooker 3. Since scattered substances such as the above are invaded, the insides of the exhaust ports 8a and 8b are easily soiled. The cooking cooker 100 according to the present embodiment is provided with movable flaps 20 that can be opened and closed, which have a function of preventing the intrusion of such scattered objects, at the exhaust ports 8a and 8b.

FIG. 4 is an enlarged cross-sectional view showing the vicinity of the exhaust port of the cooking cooker. FIG. 5 is a diagram showing a state in which the flap provided in the exhaust port of the cooking cooker is half-opened. FIG. 6 is a diagram showing a state in which the flap provided in the exhaust port of the cooking cooker is fully opened. Note that FIGS. 4, 5 and 6 illustrate the periphery of the exhaust port 8b (see FIG. 3) on the right side of the main body 2.

As shown in FIG. 4, the exhaust port 8b forms a groove-like space that opens upward inside the main body 2. The front surface of the exhaust port 8b is partitioned from the space where the heating coil unit 25 is installed by a partition 21b having a through hole. The rear surface of the exhaust port 8b is separated from the outside of the main body 2 by a back plate 2b forming the rear surface of the main body 2. The lower surface of the exhaust port 8b is partitioned from the rear space 91 and the like by the water receiver 22b. The water receiver 22b has a structure for preventing water or the like from falling from the outside of the main body 2.

The flap 20 is provided near the opening of the exhaust port 8b. The flap 20 has a main body portion 20a capable of closing the exhaust port 8b, and a shaft portion 20b that rotatably supports the main body portion 20a and serves as a central axis for opening / closing movement due to rotation. The main body portion 20a and the shaft portion 20b may be integrally provided with, for example, synthetic resin or metal, may be provided as separate bodies and fixed to each other, or may be provided as separate bodies and connected via a hinge or the like. You may.

The main body 20a of the flap 20 is provided in a plate shape that matches the shape and size of the exhaust port 8b, and in a substantially rectangular shape in a plan view. The shaft portion 20b extends in the left-right direction of the main body 2 of the cooking cooker 100. Both ends of the shaft portion 20b are rotatably supported on the main body 2 side at both ends of the exhaust port 8b in the left-right direction.

An actuator (not shown) that drives the opening / closing operation of the flap 20 is built in the main body 2 on one end side in the left-right direction of the exhaust port 8b. For example, the shaft portion 20b of the flap 20 can be provided in a structure connected to the output shaft of the stepping motor via a gear. The flap 20 automatically rotates about the shaft portion 20b by the operation of the actuator, and stands still at a predetermined inclination angle to open or close the exhaust port 8b.

The flap 20 shown in FIG. 4 is in a state where the exhaust port 8b is closed. As shown in FIGS. 5 and 6, the flap 20 opens downward from the closed state of the exhaust port 8b to open the exhaust port 8b. When the exhaust port 8b is opened, the air that has taken waste heat from the heat generating parts such as the heating coil unit 25 and the electronic parts of the control circuit unit 15 is collected from the substrate case 74 and the top plate 6 on which the heating coil unit 25 is installed. From the space between them, it goes out to the inside of the exhaust port 8b through the through hole of the partition 21b, and is discharged to the outside of the main body 2 from the upper opening.

In the flaps 20 shown in FIGS. 4 to 6, the shaft portion 20b, which is the central axis of rotation for opening and closing the exhaust port 8b, is located at the rear portion of the exhaust port 8b, and the shaft portion 20b is located at the rear portion of the main body portion 20a. There is. Therefore, the front side of the flap 20 is opened downward, and when the flap 20 is open, substantially the entire opening of the exhaust port 8b is opened.

A cooking utensil 92 or the like may be placed on the upper surface of the main body 2 in which the exhaust port 8b is open or on the top plate 1a on the upper surface of the system kitchen 1. When the flap 20 is opened downward, the exhaust port 8b cannot be opened when the cooking utensil 92 is placed on the flap 20 or when the operation of the cooking utensil 92 and the flap 20 interfere with each other. Therefore, waste heat and the like can be reliably discharged.

Further, if oil splashes, spills, or the like occur during cooking using the electromagnetic cooker 3, there is a possibility that scattered substances such as oil droplets and water droplets may enter the inside of the exhaust port 8b. If scattered matter enters the inside of the exhaust port 8b, the inside of the main body 2 becomes dirty and unsanitary. However, if the exhaust port 8b is provided with non-movable flaps, fins, louvers, etc., it is difficult to clean by wiping or the like.

On the other hand, when the flap 20 is in the form of opening downward, the scattered matter flying from the front side of the main body 2 easily adheres to the upper surface of the flap 20, but it becomes difficult to adhere to the inner surface of the exhaust port 8b. .. Since the upper surface of the flap 20 can be easily cleaned by wiping or the like, the periphery of the exhaust port 8b can be easily kept clean.

In the flap 20, the upper surface of the main body 20a may be horizontal when the exhaust port 8b is closed, or the upper surface of the main body 20a may be inclined as long as the exhaust port 8b can be closed. However, as long as it does not interfere with the cooking utensil 92 or the like, a part of the main body 20a may have a shape protruding upward.

Further, the flap 20 may have a three-dimensional shape such as unevenness formed on the upper surface or the lower surface of the main body 20a for various functions, design, and the like. However, since it is premised that dirt or the like due to scattered matter adheres to the main body portion 20a, it is preferable that at least the upper surface is smooth from the viewpoint of certainty of cleaning by wiping or the like.

The flap 20 shown in FIG. 5 is in a state where the exhaust port 8b is half-opened. The flap 20 shown in FIG. 6 is in a state where the exhaust port 8b is fully opened. The flap 20 can be provided so that the maximum inclination angle of the main body portion 20a is an arbitrary angle. For example, as shown in FIG. 6, the main body portion 20a can be provided so as to open to a position where the main body portion 20a substantially abuts on the rear surface (rear surface plate 2b) of the exhaust port 8b.

In the flaps 20 shown in FIGS. 4 to 6, since the shaft portion 20b is located at the rear portion of the exhaust port 8b and the shaft portion 20b is located at the rear portion of the main body portion 20a, the angle in the state where the exhaust port 8b is closed is 0 degrees. As a result, the maximum angle that opens downward is 90 degrees or less. When the opening angle of the flap 20 is 90 degrees or less, even when the flap 20 is fully opened, scattered matter flying from the front side of the main body 2 easily adheres to the upper surface of the flap 20, so that the exhaust port 8b You can keep the inside clean.

The flap 20 can be provided so as to stand still with the exhaust port 8b half-opened, as shown in FIG. 5, in addition to the state in which the exhaust port 8b is closed and the state in which the exhaust port 8b is fully opened. For example, the flap 20 can be operated by a stepping motor so as to stand still at an arbitrary inclination angle of 0 degree or more and 90 degrees or less. When the flap 20 is stopped in a half-opened state, it is possible to suppress the invasion of scattered matter into the inside of the exhaust port 8b while keeping the amount of waste heat and the like discharged from the inside of the main body 2 high.

FIG. 7 is an enlarged cross-sectional view showing the vicinity of the exhaust port of the cooking cooker. FIG. 8 is a diagram showing a state in which the flap provided in the exhaust port of the cooking cooker is fully opened. Note that FIGS. 7 and 8 illustrate the periphery of the exhaust port 8a (see FIG. 2) provided on the left side of the main body 2.

As shown in FIG. 7, the exhaust port 8a forms a groove-shaped space that opens upward inside the main body 2 in the same manner as the exhaust port 8b. The front surface of the exhaust port 8a is partitioned from the space where the heating coil unit 25 is installed by a partition 21a having a through hole. The rear surface of the exhaust port 8a is separated from the outside of the main body 2 by a back plate 2b forming the rear surface of the main body 2. The lower surface of the exhaust port 8a is separated from the space below by a water receiver 22a having an opening 23. Below the water receiver 22a, there is an outlet of the exhaust duct 36k, and the inside of the exhaust port 8a and the inside of the exhaust duct 36k communicate with each other through the opening 23.

The flap 20 is provided near the opening of the exhaust port 8a, similarly to the exhaust port 8b. As shown in FIG. 8, the flap 20 opens downward from the closed state of the exhaust port 8a to open the exhaust port 8a. When the exhaust port 8a is opened, the oil smoke generated in the oven 4 and the air that has taken away the waste heat inside the oven 4 go out to the inside of the exhaust port 8a through the opening 23, and the heating coil unit 25 is installed. Together with the air discharged from the created space through the through hole of the partition 21a, the air is discharged to the outside of the main body 2 through the upper opening.

The shape, structure, and operation of the flap 20 provided in the left exhaust port 8a can be the same as that of the flap 20 provided in the right exhaust port 8b. The flap 20 may be controlled so that the opening and closing are synchronized on the left and right sides of the main body 2, or the opening and closing may be controlled independently on the left and right sides of the main body 2. For example, when the flap 20 provided on the left exhaust port 8a where the oven 4 is arranged is not stopped in a half-open state, but is operated so as to open to a position where it substantially abuts on the rear surface (rear plate 2b) of the exhaust port 8a. Since the oil smoke discharged from the exhaust duct 36k is less likely to come into contact with the lower surface of the flap 20, it is possible to prevent the lower surface, which is relatively difficult to clean such as wiping, from becoming dirty.

FIG. 9 is a block diagram illustrating control of the cooking cooker.
As shown in FIG. 9, the electromagnetic cooker 3 provided with the mounting portions 3a to 3c, the blower device 12, the exhaust device 36, and the upper heater 27a and the lower heater 27b of the oven 4 are control units of the cooking cooker 100. It can be controlled by 45.

The operation unit 5 and the upper surface operation unit 9 send an input signal indicating power on / off and a heating power setting to the control unit 45 in response to an input to a switch key or the like by a user of the electromagnetic cooker 3 or the oven 4. send. The control unit 45 receives the input signal and sends a display signal indicating power on / off, heating power setting, cooking progress, etc. to the operation unit 5 and the upper surface display unit 10, and sends the operation unit 5 and the upper surface display unit to the operation unit 5. Display on 10 monitors.

The control unit 45 sets the inverter control means 61a to 61c, the upper heater control means 64, and the lower heater control means 65 based on the settings input by the user and the program such as automatic cooking built in in advance. A control signal is sent to control the on / off and thermal power of each heating coil unit 25, the upper heater 27a, and the lower heater 27b. Further, the control unit 45 receives a temperature signal output by the temperature sensor of each heating coil unit 25 and a temperature signal output by the temperature sensor in the oven 4.

The heating in the mounting portions 3a to 3c of the electromagnetic cooker 3 is controlled by the inverter by the control unit 45. The mounting portions 3a to 3c are provided with inverter circuits 60a to 60c for supplying electric power to the heating coil, and inverter control means 61a to 61c for controlling the inverter circuits 60a to 60c.

The inverter control means 61a to 61c are controlled by a control signal sent from the control unit 45 by input from the upper surface operation unit 9. For example, when the power is turned on / off, the strength of the thermal power is input to the upper surface operation unit 9, a control signal is sent to the inverter control means 61a to 61c, and the electric power supplied to the heating coil of each heating coil unit 25. Is controlled.

The inverter control means 61a to 61c control the inverter circuits 60a to 60c by setting the power to each heating coil unit 25, starting and stopping energization, and monitoring and correcting the power consumption of each heating coil unit 25. .. The inverter control means 61a to 61c calculate the power consumption from the input current and the input voltage of the heating coil units 25 sent from the inverter circuits 60a to 60c, and the thermal power of the mounting portions 3a to 3c is as targeted. Power is supplied so as to become.

The operation / stop and output of the blower 12, the exhaust device 36, the upper heater 27a and the lower heater 27b are controlled by the control unit 45. The blower 12, the exhaust device 36, the upper heater 27a, and the lower heater 27b have a blower control means 62, an exhaust device control means 63, an upper heater control means 64, and a lower heater control, respectively, for controlling operation / stop, output, and the like. Means 65 are provided.

The upper heater control means 64 and the lower heater control means 65 are controlled by a control signal sent from the control unit 45 by input from the operation unit 5. For example, when the strength of the heating power, the menu, the classification of the object to be heated 30 and the like are set in the operation unit 5, a control signal is sent to the upper heater control means 64 and the lower heater control means 65, and the amount of the object to be heated 30 depends on the amount. The amount of heat to the oven 4 is controlled according to the changing rate of temperature rise.

The upper heater control means 64 and the lower heater control means 65 adjust the heating power of the oven 4 by controlling ON / OFF of the upper heater 27a and the lower heater 27b under the monitoring of the temperature of the oven 4.

Further, the blower control means 62 and the exhaust device control means 63 are controlled by a control signal sent from the control unit 45 based on the settings built in in advance according to the usage state of the electromagnetic cooker 3 and the oven 4. .. For example, a control signal is sent to the blower control means 62 and the exhaust device control means 63 according to the power consumption of the electromagnetic cooker 3 and the oven 4, the temperature of the electromagnetic cooker 3 and the oven 4, and the like, and the blower 12 and the exhaust are exhausted. The rotation of the fan of the device 36 is controlled.

The opening / closing operation of the flap 20 can be controlled by the control unit 45. The flap 20 can be provided with a flap control means 66 that automatically controls the opening / closing operation of the flap 20. The flap control means 66 is provided so as to automatically control the actuator that drives the flap 20.

The flap control means 66 can be controlled by a control signal sent from the control unit 45 based on a pre-built setting according to the usage state of the electromagnetic cooker 3 and the usage state of the oven 4. The flap control means 66 controls, for example, the operation of the stepping motor and the step angle to change the tilt angle of the flap 20 to a preset closed angle, a half-open angle, a fully open angle, and the like.

The opening and closing of the flap 20 can be controlled, for example, so as to be synchronized with the operation of the blower device 12 and the operation of the exhaust device 36. Further, the opening and closing of the flap 20 can be controlled based on, for example, the power consumption of the heating coil unit 25 and the power consumption of the upper heater 27a and the lower heater 27b. Further, by providing a temperature sensor at an appropriate position, control can be performed based on the temperature of the space where the heating coil unit 25 is installed, the temperature of the control circuit unit 15, the temperature of the cooking cabinet 26, and the like.

The flap 20 can be controlled to a closed state when the blower 12 and the exhaust device 36 are not operating (see FIGS. 4 and 7). When the flap 20 is in the closed state, scattered matter flying from the front side of the main body 2 adheres to the upper surface of the flap 20 and does not adhere to the inner surface of the exhaust ports 8a and 8b, so that cleaning by wiping or the like is easy. The area around the exhaust port 8b becomes clean.

On the other hand, the flap 20 can be controlled to be in an open state when at least one of the blower device 12 and the exhaust device 36 is operating (see FIGS. 5, 6, and 8). When the flap 20 is in the open state, the amount of oil smoke, waste heat, etc. discharged from the inside of the main body 2 is secured, so that the cooling efficiency of the heating coil unit 25 and electronic parts and the cleanliness of the atmosphere of the oven 4 and the like are improved. Become good.

Further, the flap 20 can be controlled to be in a half-open state when the heating coil unit 25 is in operation (see FIG. 5). When the heating coil unit 25 is in operation, it is highly possible that cooking is being performed on the top plate 6. When the flap 20 is half-opened in such a state, oil smoke, waste heat, and the like are discharged from the inside of the main body 2 while suppressing the intrusion of scattered matter during cooking into the exhaust ports 8a and 8b, so that the exhaust port 8a , 8b can be kept clean inside.

When controlling the flap 20 to the half-open state, the opening angle (opening) of the flap 20 can be provided so as to be changed according to the power consumption of the heating coil unit 25. For example, the power consumption is calculated from the input current and the input voltage of each heating coil unit 25 sent from the inverter circuits 60a to 60c, and the control signal is sent to the flap control means 66. In the flap 20, for example, when the power consumption of the heating coil unit 25 exceeds a predetermined lower threshold value and is equal to or lower than a predetermined upper threshold value, the exhaust ports 8a and 8b are in a half-opened state, and the flap 20 is in a state where the exhaust ports 8a and 8b are half-opened. When the amount exceeds, the exhaust ports 8a and 8b can be controlled to be fully opened.

Further, the flap 20 can be controlled to be in a fully open state when the heating coil unit 25 is not operating and the oven 4 is operating, or when the heating coil unit 25 and electronic components are cooled down after the operation. 6 and 8). When the heating coil unit 25 is not operating or when it is cooled down, there is a high possibility that cooking is not performed on the top plate 6. When the flap 20 is fully opened in such a state, the cooling efficiency of the heating coil unit 25 and the electronic parts and the cleaning of the atmosphere of the oven 4 are suppressed while suppressing the intrusion of scattered substances into the exhaust ports 8a and 8b during cooking. The degree can be improved.

When controlling the flap 20 to the fully open state, the opening timing of the flap 20 can be controlled according to the temperature of the space in which the heating coil unit 25 is installed, the temperature of the control circuit unit 15, and the like. For example, the temperature is detected by a temperature sensor provided at a predetermined position, and a control signal is sent to the flap control means 66. The flap 20 is set so that the exhaust ports 8a and 8b are fully opened when, for example, the temperature of the space where the heating coil unit 25 is installed or the temperature of the control circuit unit 15 exceeds a predetermined threshold value. Can be controlled.

According to the above-mentioned cooking cooker 100, since the flaps 20 that can open and close the exhaust ports 8a and 8b are provided, by closing the flaps 20, scattered matter or the like during cooking can be prevented from entering the inside of the exhaust ports 8a and 8b. Can be prevented. When the flap 20 is normally closed and there is little need to exhaust the waste heat in the main body, if the exhaust ports 8a and 8b are closed, dust and the like in the atmosphere will fall into the exhaust ports 8a and 8b. It is also possible to easily clean the upper surface of the flap 20 together with the upper surface of the system kitchen 1 by wiping or the like. Further, by providing the actuator for driving the flap 20, the exhaust amount can be precisely controlled to an appropriate amount according to the amount of heat generated inside the main body 2, so that the insides of the exhaust ports 8a and 8b are unnecessary. It is easy to clean without getting dirty. Therefore, it is possible to provide a cooking cooker in which scattered matter does not easily enter the inside of the exhaust port and dirt around the exhaust port can be easily cleaned.

Next, the cooking device according to the modified example of the present invention will be described.

FIG. 10 is a cross-sectional view showing a modified example of the flap by enlarging the vicinity of the exhaust port of the cooking cooker. FIG. 11 is a diagram showing a state in which the flap according to the modified example provided in the exhaust port of the cooking cooker is fully opened. Note that FIGS. 10 and 11 illustrate an exhaust port 8a (see FIG. 2) provided on the left side of the main body 2.

As shown in FIG. 10, in the exhaust port 8a provided on the left side of the main body 2 where the oven 4 is arranged, the central axis of rotation for opening and closing the exhaust port 8a is located in the middle portion of the exhaust port 8a. It is also possible to provide the flap (flap according to the modified example) 20A. In addition, such a flap 20A may be provided in both the exhaust port 8b provided on the right side of the main body 2 where the oven 4 is not arranged, and the left and right exhaust ports 8a and 8b.

In the flap 20A, a shaft portion 20b, which is a central axis of rotation for opening and closing the exhaust port 8a, is located at an intermediate portion in the front-rear direction of the exhaust port 8a, and is hung on the exhaust port 8a along the left-right direction. Has been done. In the flap 20A, the shaft portion 20b is located in the middle portion on the rear side of the main body portion 20a, and the intermediate portion on the rear side of the flap 20A is rotatably supported.

The flap 20A shown in FIG. 10 is a state in which the exhaust port 8a is closed. The flap 20A shown in FIG. 11 is a state in which the exhaust port 8a is fully opened. The flap 20A can be provided so that the maximum inclination angle of the main body portion 20a is an arbitrary angle. For example, as shown in FIG. 11, the main body portion 20a can be provided so as to open to a position where it substantially abuts on the rear surface (rear surface plate 2b) of the exhaust port 8a. Other shapes, structures, and operations of the flap 20A can be the same as those of the flap 20 described above.

In the flaps 20A shown in FIGS. 10 to 11, since the shaft portion 20b is located in the middle portion of the exhaust port 8b and the shaft portion 20b is located in the middle portion of the main body portion 20a, the angle in which the exhaust port 8a is closed can be set. As 0 degrees, the maximum angle that opens downward is an angle that exceeds 90 degrees. If the opening angle of the flap 20A exceeds 90 degrees, when the flap 20A is fully opened, the oil smoke discharged from the lower exhaust duct 36k easily comes into contact with the upper surface of the flap 20A and is discharged to the outside of the main body 2. Oil smoke and waste heat are likely to be directed toward the front side of the main body 2.

Normally, the exhaust port for exhausting waste heat and the like in the main body of the cooking cooker is open at the rear of the upper surface of the main body, and is therefore close to the wall surface of the kitchen. Further, in the ventilation device provided above the system kitchen, the hood or the like for sucking the airflow is often on the front side of the wall surface of the kitchen and overhangs directly above the stove. In such a positional relationship, the airflow emitted from the exhaust port is attracted to the wall side by the Coanda effect, so that the efficiency of discharging oil smoke and waste heat to the outside deteriorates.

On the other hand, according to the flap 20A according to the modified example, the oil smoke and waste heat discharged to the outside of the main body 2 are likely to be directed toward the front side of the main body 2, so that the oil smoke and waste heat are discharged to the outside efficiency. Can be raised. Further, since the oil smoke is easily directed toward the front side of the main body 2, oil stains and the like are less likely to adhere to the wall surface of the kitchen. Further, since the oil smoke discharged to the outside of the main body 2 easily comes into contact with the upper surface of the flap 20A, the oil droplets discharged from the oven 4 are trapped on the upper surface of the flap 20A which can be easily cleaned by wiping or the like. Can be done.
