Description

  The present invention relates to a cooking device having a function of interlocking a ventilation device wirelessly.

  In the cooking device that is connected wirelessly to the ventilation device, 4 infrared LEDs are arranged below the top plate so as to avoid each pan mounting part. When light is emitted, an infrared light signal is transmitted to the upper range hood fan photodiode through the top plate, and when the photodiode receives the light signal, the fan device of the range hood fan is driven and controlled. (For example, refer to Patent Document 1).

  In addition, a transmitting means for emitting infrared rays below the top plate on which the cooking container is placed, an operation switch for setting the heating amount, and a light receiving device (ventilation fan) that operates in conjunction with the cooker body in response to a signal from the transmitting means. There is a cooking device in which the infrared light emitted from the transmission means is transmitted to the receiving device via the top plate and remotely controlled (see, for example, Patent Document 2).

Japanese Unexamined Patent Publication No. 2003-114028 (page 4-6, FIG. 1-2) JP 2003-229240 A (page 3-4, FIG. 1)

  When the food to be cooked in a cooking pan or the like is heated by a heating device, odor and water vapor are generated immediately after heating. However, in the heating cooker of Patent Documents 1 and 2, heating of the food to be cooked is started at the same time. Since the ventilator is in operation, an ascending airflow is not sufficiently generated in the early stage of cooking, and there is a possibility that odors and water vapor generated in the early stage of cooking may not be discharged reliably.

  In addition, the infrared LED may tilt or fall due to variations during assembly of the control board. However, in Patent Documents 1 and 2, the infrared transmission window provided on the top plate is formed in a circle. Some or all of the infrared rays transmitted from the infrared LED may deviate from the transmission window, which may reduce the infrared reception efficiency of the ventilator.

  Furthermore, although infrared LED has the characteristic that irradiation intensity | strength falls by the raise of ambient temperature, in patent document 1, 2, since infrared LED is arrange | positioned under the top plate and the vicinity of a heating coil, it is heating. There exists a problem that irradiation intensity | strength falls by the radiant heat from a coil or a heated cooking pan.

  In addition, since the infrared transmission window is provided on the top plate, when a large cooking pan or the like is placed on the top plate, a part or all of the transmission window is shielded or the transmission window is blocked by boiled broth from the cooking pan. It may become dirty or partially or completely blocked. For this reason, there exists a possibility that the infrared rays from infrared LED may be attenuated or blocked.

  The present invention has been made to solve the above-described problems, and can efficiently discharge odors and water vapor generated at the start of cooking, and there is no fear that the infrared signal is attenuated or blocked. An object of the present invention is to provide a cooking device having a function of interlocking with a ventilator whose light projecting means is not easily affected by heat.

The cooking device according to the present invention includes a heating unit, a control unit for controlling the output of the heating unit, an infrared light projecting unit, a control unit for the infrared light projecting unit, and the like. A main body case provided with a front operation unit having an adjustment dial switch and the like;
The top plate held by the holding frame is provided with an infrared light transmitting portion corresponding to the infrared light projecting means, and comprises a top plate attached to the upper surface opening of the main body case,
When the main switch is turned on, an infrared signal from the infrared light projecting means is received by a ventilator provided above to drive the ventilator.

  According to the present invention, before the cooking (heating) of the object to be cooked is started, the ventilator is activated to generate the upward air flow in advance, so that the odor and water vapor generated immediately after the start of cooking are efficiently discharged. In addition, since the ventilator is stopped after a predetermined time has elapsed after the cooking is completed, the odor and water vapor remaining in the cooking place can be surely exhausted, so that the cooking place is maintained in a favorable environment. be able to.

  The ventilation device 55 includes a hood portion 56 and a ventilation fan 57 provided in the hood portion 56, and an infrared ray that receives infrared signals from the infrared LEDs 23 a to 23 c of the heating cooker 1 at the upper end portion of the hood portion 56. The light receiving portion 58 is provided, and an illuminating portion 59 is provided in the lower central portion of the hood 56. And when the light-receiving part 58 receives an infrared signal, the drive circuit of the ventilation fan 57 and the lighting circuit of the illumination part 59 are turned ON.

Next, the outline of the cooking procedure of the object to be cooked by the heating cooker according to the present embodiment will be described.
First, as shown in FIG. 5, the cooking pan 40 in which an object to be cooked is placed is placed on any of the placement portions 30 a to 30 c of the top plate 27. In addition, in the following description, the case where the cooking pan 40 is mounted on the mounting part 30a (1st heating part 4) is described. Next, the main switch 16 of the front operation unit 15 is turned on, the heating power adjustment dial switch 17a is pushed out and held in the ON state, and the standby state is set.

  As a result, a control signal is sent from the light emission control unit 20 to the infrared LED 23a to turn on, and an infrared signal is output from the infrared LED 23a as shown in FIG. This infrared signal is received by the light receiving part 58 of the ventilation device 55 via the infrared light transmitting part 33a of the top plate 27, and the ventilation fan 58 is driven, the illumination part 59 is lit, and it is confirmed that the ventilation fan 58 is activated. The

Thereafter, the heating power adjustment dial switch 17a is rotated clockwise or counterclockwise to set the desired heating power (for example, weak, medium, strong) and cooking is performed. At this time, the thermal power (output) of the first heating unit 4 is displayed on the thermal power display unit 31a. The heating power adjustment dial switches 17a to 17c are sequentially switched from weak, medium, strong, and off by turning.
When cooking is finished, the heating power adjustment dial switch 17a is pushed in and turned off, and the output of the first heating unit 4 is stopped.

When the timer time has elapsed, the output is automatically stopped, and after a predetermined time has elapsed, the ventilator 55 is stopped.

Next, several different examples of the heating cooker according to the present embodiment will be described.
[Example-1]
In the heating cooker of FIG. 1, the infrared light transmitting portions 33 a to 33 c provided on the top plate 27 are formed in a circular shape, but the infrared LEDs 23 a to 23 c mounted on the light emission control board 20 vary when assembled. As a result, the top plate 27 may block a part of the infrared signal and reduce the transmission efficiency, or may block the whole and block the light receiving unit 58 of the ventilation device 55 from receiving light.
In this example, as shown in FIG. 8, infrared light transmitting portions 33 a to 33 c provided on the top plate 27 are formed in a rectangular shape that is long in the front-rear direction so as to cope with such a case.

  That is, as shown in FIG. 9A, the length Y in the front-rear direction of the infrared light transmitting portions 33a to 33c (hereinafter sometimes simply referred to as 33) is 1.2 with respect to the width X in the left-right direction. The direction in which the infrared LED 23 tends to fall down (in the case of the lower figure of FIG. 9A), the infrared LED 23 tends to tilt or fall in the front-rear direction, but not in the left-right direction. In which the body case 1 is less likely to tilt or fall). In addition, as shown in FIG.9 (b), you may form the infrared light transmission part 33 in elliptical shape on the same conditions.

  According to this example, even if the infrared LED 23 is tilted in the front-rear direction or falls down, the infrared light transmitting part 33 is long in the front-rear direction, so that part or all of the infrared signal is blocked by the top plate 27. Therefore, the light receiving unit 58 of the ventilation device 55 can reliably receive the infrared signal, and the reception efficiency can be improved.

[Example-2]
In the present embodiment, when the main switch 16 is turned on and the heating power adjustment dial switch 17c of any one of the first to third heating units (for example, the heating unit 6) is pushed out (when turned ON), The ventilator 55 starts to operate with the processing (exhaust) capacity “medium”, and the heating power adjustment dial switch 17c is rotated to adjust the heating power of the third heating unit 6, and when cooking is started, the ventilation device 55 Processing capacity changes to “strong”.
When cooking is finished and the heating power adjustment dial switch 17c is pushed in and the power supply to the third heating unit 6 is turned off, the processing capacity of the ventilator 55 returns to “medium” again, and the ventilator 55 stops when a predetermined time elapses. It is what you do.

According to this example, during cooking, the processing capacity of the ventilator 55 can be set to “strong”, smoke and water vapor generated by cooking can be efficiently discharged, and a comfortable cooking environment can be provided. It is possible to prevent dew condensation and oil mist from adhering to the 55 light receiving part 58 and improve the infrared signal receiving performance of the light receiving part 58.
Further, by providing an appropriate processing capacity of the ventilation device 55, unnecessary operation noise of the ventilation device 55 other than during cooking can be reduced.

[Example-3]
In this example, in the first embodiment, when the main switch 16 is first turned on, each of the thermal power display units 21a to 21c emits light, and then one of a plurality of roaster keys provided on the upper surface operation unit 28 (for example, cooking When the menu selection key) is pressed, the center thermal power display 21c emits light in a different color, and at the same time, the infrared LED 23c outputs an infrared signal to activate the ventilator 55. Then, for example, when the roaster key is pressed, the roaster 13 The heating unit (not shown) is energized to start cooking.
When cooking is finished, when the roaster stop key of the upper surface operation unit 28 is pressed, the energization to the heating unit is turned off, and then the ventilation device 55 stops when a predetermined time elapses.

According to this example, before the cooking of the food to be cooked by the roaster 13 is started, the ventilator 55 is activated to generate an updraft, so that odors and water vapor generated immediately after the start of cooking can be discharged. . Moreover, since the ventilation apparatus 55 is operating for a predetermined time after the cooking is stopped after the cooking is finished, it is possible to discharge odors and water vapor remaining in the cooked food after cooking.
Further, by pressing the roaster key, the central thermal power display unit 21c emits light in a different color, so that the user can be informed that the operation of the ventilation device 55 has started.

[Example-4]
In this embodiment, in Embodiment 1, a switch (not shown) connected to the light emission control unit 20 and turned on and off by opening and closing the door 14 is provided on the contact surface between the main body case 1 and the door 14 of the roaster 13. It is a thing.
First, the food to be cooked is put in the roaster 13 and the main switch 16 is turned on. Next, for example, the cooking menu selection key of the roaster is pressed to select a menu suitable for the food to be cooked. Press the key to energize the heating section and start cooking (heating). At this time, the ventilator 55 is operated with, for example, the processing capability “medium” by the infrared signal from the infrared LED 23c.

During cooking, when the roaster 13 is pulled out to confirm the degree of baking of the food, the switch is turned on (or turned off), the infrared signal from the infrared LED 23 is controlled, and the processing capacity of the ventilator 55 is “medium. It changes from “strong” to “strong” and efficiently discharges smoke and water vapor released in large quantities from the inside of the roaster 13. When cooking is completed, the energization of the heating unit is stopped by pressing the roaster start key, and the ventilation device 55 continues to operate for a predetermined time instead of the processing capacity “medium”.
Then, when the roaster 13 is pulled out to take out the object to be heated, the processing capacity of the ventilator 55 changes from “medium” to “strong”, and smoke and water vapor released in large quantities from the inside of the roaster 13 Is discharged. When the roaster 13 is pushed in again, the processing capacity of the ventilation device 55 returns to “medium” and stops when a predetermined time has elapsed.

According to this example, when confirming the degree of baking of the cooking object during cooking with the roaster 13, or when the roaster 13 is pulled out after cooking, the processing capacity of the ventilator 55 is automatically set to “strong”. Since it changed, smoke and water vapor which come out in large quantities from the inside of the roaster 13 can be discharged efficiently. Thereby, it is possible to prevent condensation and oil mist from adhering to the light receiving portion 58 of the ventilation device 55.
Furthermore, since the processing capability of the ventilator 55 is changed as necessary, it is possible to reduce the operation sound of the ventilator 55 except when necessary.

[Example-5]
In this embodiment, in the first embodiment, the heating power adjustment dial switches 17a to 17c are pushed out and turned on to turn on the display units 22a and 22b or the central display unit 22c in use, and the ventilator 55 is connected to the thermal power adjustment dial switch. The timing to operate in conjunction with 17a to 17c is notified to the user.
According to this example, since the operation start timing of the ventilator 55 can be visually confirmed, for example, even when the ambient noise is large, the start of the operation of the ventilator 55 can be visually confirmed.

  According to the present embodiment configured as described above, the ventilator 55 is activated before the cooking (heating) of the object to be cooked to generate the updraft in advance. Odor and water vapor can be efficiently discharged, and the ventilation device 55 is stopped after a lapse of a predetermined time after cooking, so that the odor and water vapor remaining in the cooking area can be reliably exhausted. The kitchen can be maintained in a favorable environment. In addition, the above-described effects can be obtained for the other examples 1 to 5 of the present embodiment.

Next, the heating power adjustment dial switch 17a is rotated to set the heating power (output) of the first heating unit 4, whereby cooking of the food to be cooked is started.

  Further, when the main switch 16 is turned on but the heating power adjustment dial switch 17a is not operated in step S-2, the ventilation fan switch 29 of the upper surface operation unit 28 is operated (step S-4). In this case, when the ventilation fan switch 29 is pressed once, an operation signal (infrared signal) of processing capability “medium” is transmitted from the infrared LED 23a to the ventilation fan device 55 (see step S-3). During cooking, when the ventilation fan switch 29 is sequentially pressed twice or more (step S-5) and the operation modes of “medium”, “strong”, “weak” and “off” of the ventilation device 55 are set, infrared rays are set. An operation signal corresponding to the operation mode is transmitted from the LED 23a to the ventilator 55 (step S-7).

  When cooking is completed, the heating power adjustment dial switch 17a is pushed in, and energization to the first heating unit 17a is stopped (step S-8). At this time, a timer (delay operation) signal is transmitted from the infrared LED 23a to the ventilation device 55, and the ventilation fan 57 stops after a predetermined time has elapsed (step S-9).

If the heating power adjustment dial switch 17a is not pushed out from the beginning or the heating power adjustment dial switch 17a is not pushed in at step S-8, the ventilation fan switch 29 is pushed to select the "OFF" operation mode (step S-10). ). Thereby, an infrared signal for stopping operation is transmitted from the infrared LED 23a to the ventilation device 55, and the ventilation fan 57 is stopped. In this case, the timer (delay operation) does not operate.
In the above description, the case where cooking is performed by the first heating unit 4 has been described, but the same applies to the case where cooking is performed by the second heating unit 17b and the third heating unit 17c.

[Embodiment 4]
In the first to third embodiments, when the main switch 16 is turned on and the thermal power adjustment dial switches 17a to 17c or the ventilation fan switch 29 are operated, infrared signals are output from the infrared LEDs 23a to 23c to drive the ventilation device 55. However, in the present embodiment, when the main switch 16 is turned on, infrared signals are output from the infrared LEDs 23a to 23c to drive the ventilator 55.

  In the present embodiment, the main switch 16 and the infrared LEDs 23a to 23c are connected to the light emission control unit 20, and when the main switch 16 is turned on, the infrared LEDs 23a to 23c are turned on to output infrared signals, and the ventilation device The light receiving unit 58 receives the light and starts operation, and the illumination unit 59 is turned on.

Then, the heating power adjustment dial switches 17a to 17c are pushed out, the first to third heating units 4 to 6 are energized and rotated, set to a desired heating power, and cooking is started. When cooking is finished, the heating power adjustment dial switches 17a to 17c are pushed in to stop energization of the first to third heating units 4 to 6, and the main switch 16 is turned off. As a result, the infrared LEDs 23a to 23c are turned off, but the ventilation device 55 is stopped after the operation for a predetermined time.
Note that the second and third embodiments described above can also be implemented in this embodiment.

  Even in the present embodiment, substantially the same effect as in the first embodiment can be obtained, but furthermore, since the ventilation device 55 starts operation simultaneously with the turning on of the main switch 16, the cooking object is heated. Ascending airflow is generated from the front, and odor and water vapor generated immediately after heating can be discharged.
