  In a built-in heating cooker as in Patent Literature 2, when a communication light emitting unit is arranged below a top plate as in Patent Literature 1, the heating unit side passes through the top plate to a light receiving unit of a range hood. An infrared signal is transmitted. For this reason, the infrared signal may be blocked by a cooking container or a dish placed on the top plate. As described above, when the infrared signal is blocked by the cooking container or the like immediately after being emitted from the communication light-emitting unit, the infrared signal reaching the communication light-receiving unit of the range hood is extremely reduced, and the cooker is cooked in the range hood. Interlocked operations may not be performed.

  The present invention has been made in order to solve the above-described problems, and an object of the present invention is to provide a cooking device capable of stably linking a range hood.

  A heating cooker according to the present invention includes a top plate installed on a kitchen table, a heating unit provided below the top plate, and a first side surface of the kitchen table and a second side surface facing the first side surface. An operation unit is provided so as to be able to be pulled out, and an infrared signal is transmitted to a range hood provided above the top plate, and includes a transmission unit provided in the operation unit.

  According to the heating cooker of the present invention, since the transmission unit is provided in the operation unit, it is possible to suppress the infrared signal from being blocked by the cooking container or the like as compared with the conventional case where the transmission unit is provided below the top plate. As a result, the amount of infrared rays reaching the range hood can be secured to a certain level or more, and the range hood can be stably linked.

  The operation board 38 is mounted with various circuits, transmits signals from the electronic components to the control device 13, and operates the electronic components based on the signals from the control device 13. When the user presses the button 32 via the dome portion 41, the switch portion 37a is pressed by the lower portion of the button 32, and a signal is output from the switch 37.

  The appearance of the operation unit 3a, particularly, the operation surface will be described with reference to FIGS. On the operation surface, operation units 31a, 31b, 31c are provided corresponding to the respective heating units 11. Specifically, the operation surface is partitioned into three regions by two partition portions 42. The partition section 42 may be, for example, one displayed on the operation sheet 40 by printing, or may be a linear projection formed on the operation sheet 40.

  A left operating section 31a for operating the left heating section 11 is provided in the left area, a central operating section 31b for operating the central heating section 11 is provided in the central area, A right operation unit 31c for operating the right heating unit 11 is provided in the area.

  When the transmission unit 4 is configured by an infrared LED, the irradiation angle may be set to a wide angle. In this case, the transmitting unit 4 may be composed of a plurality of infrared LEDs, and the infrared rays may be combined so that the distribution of infrared rays is smaller in the center than in the surroundings. Specifically, infrared rays emitted from the operation surface in the normal direction are omitted, and the amount of infrared rays emitted obliquely upward is secured. With such a configuration, the amount of infrared rays blocked by the finger of the user operating the operation unit 3a can be reduced.

  FIG. 7 is a block diagram illustrating functions of the heating cooking system including the cooking device and the range hood according to Embodiment 1 of the present invention. In the heating cooker 100, when the switch 37 of the operation unit 3 is operated, a signal is output from the switch 37. The output signal is input from the operation board 38 to the control device 13 of the main unit 1 via a lead wire. Further, the detection value of the top plate temperature detection unit 14 and the detection value of the container temperature detection unit 15 are input to the control device 13. The control device 13 controls each device such as the heating unit 11 and the transmission unit 4 according to the input signal and each detection value. When a signal is input from the switch 37, the control device 13 transmits preset information to the operation board 38 and causes the display device 33 to display the information.

  For example, when the menu button 32c is pressed by the user, the control device 13 causes the display device 33c to display a plurality of menus stored in the memory. When the user operates the menu button 32c to select a menu and then presses the start / stop button 32d, the control device 13 performs settings according to the selected menu and supplies power to the heating unit 11. Control to be done. In the memory of the control device 13, a set temperature range, heat power, cooking time, and the like are stored in advance in association with each menu.

  The controller 13 controls the amount of electricity supplied to the heating unit 11 so that the container temperature detected by the container temperature detection unit 15 falls within the set temperature range when the heating unit 11 is energized, and adjusts the heating power. I do. When a signal is input from the start / stop button 32d to the control device 13 while the heating unit 11 is energized, the control device 13 controls the heating unit 11 to terminate the energization. I do.

  The control device 13 controls the operation of the transmission unit 4 according to a signal from the operation unit 3. For example, when a signal (heating start signal) is input from the start / stop button 32d when the heating unit 11 is not energized, the control device 13 transmits so as to transmit an infrared signal of ventilation start. The unit 4 is operated. Further, for example, when a signal (heating stop signal) from the start / stop button 32d is input while the heating unit 11 is energized, the control device 13 transmits an infrared signal indicating the end of ventilation. The transmitting unit 4 is operated. The control device 13 only needs to operate the operating units 3a and 3b operated or only the transmitting unit 4 provided in the operating units 31a, 31b and 31c.

  The timing at which the transmission section 4 transmits the infrared signal is not limited to the start and stop of the heating control, and may be any timing at which ventilation by the range hood 300 is performed during cooking. For example, when the operation unit 3 stored in the kitchen table 101 is pulled out by the user and then the operation unit 3 is operated for the first time, the transmission unit 4 transmits an infrared signal. Is also good. In this case, the button 32 and the switch 37 may be configured by a touch switch or the like.

  In range hood 300, when receiving section 304 receives an infrared signal from cooking device 100, receiving section 304 outputs a detection signal corresponding to the received infrared signal to ventilation side control section 305. When the detection signal is input from the receiving unit 304, the ventilation-side control unit 305 controls the fan driving unit 302 based on the input detection signal, and controls the rotation of the hood fan 301 via the fan driving unit 302. For example, when the receiving unit 304 receives an infrared signal for starting ventilation, the ventilation side control unit 305 controls the hood fan 301 to rotate. On the other hand, when the receiving unit 304 receives the infrared signal indicating the end of ventilation, the ventilation side control unit 305 controls the hood fan 301 to stop.

  Note that the infrared signal indicating the end of ventilation may be an infrared signal for stopping the operation of the hood fan 301 after a set time (for example, several minutes). According to such a configuration, even after the heating of the cooking container 99 by the heating unit 11 is stopped, the food fan 301 rotates for the set time. For this reason, the exhaust air generated immediately before the stop of the heating does not remain in the kitchen, and the ventilation is sufficiently performed.

  FIG. 8 is an explanatory diagram schematically showing a path of an infrared signal emitted from the transmitter of the heating cooker according to Embodiment 1 of the present invention. The transmission unit 4 of the operation unit 3 transmits the infrared signal P1 upward when heating is started and when heating is stopped. The infrared signal P1 transmitted from the transmission unit 4 passes through the operation sheet 40 and proceeds further upward. At this time, since the transmission unit 4 is provided in the operation unit 3, the transmission unit 4 is not obstructed by the cooking container 99, the plate, and the like near the heating cooker 100. In addition, since the transmission unit 4 is provided at a position farther from the user than the operation area Ao (see FIG. 5) on the operation surface, the transmission unit 4 is not easily disturbed by fingers of the user who operates the operation unit 3. After that, the infrared signal P <b> 1 reaches the receiving unit 304 provided below the range hood 300 and is received by the receiving unit 304.

  The position where the transmission unit 4 is provided in the operation unit 3 is not particularly limited to the above position. FIG. 9 is an explanatory diagram illustrating a second example of the operation unit of the heating cooker according to Embodiment 1 of the present invention. In FIG. 9, the transmission unit 4 is arranged on the back side of the operation area Ao and on the right side of the display area Ad. Also in this case, compared to the case where the transmitting unit 4 is provided on the top plate 2, it is possible to prevent the cooking container 99 from hindering the progress of the infrared signal. Further, as compared with the case of FIG. 5, the transmitting unit 4 on the kitchen side can make the distance to the front surface 101c of the kitchen table 101 longer, and the transmitting unit 4 on the living side can make the distance to the rear surface 101d of the kitchen table 101 (see FIG. 8). Can be lengthened. Therefore, it is possible to prevent the infrared signal from being hindered by the kitchen table 101, and the degree of freedom of the installation position of the receiving unit 304 in the range hood 300 is increased. Alternatively, it is not necessary to secure a space for providing the transmission unit 4 on the back side of the display area Ad of the operation unit 3a, and even when the transmission unit 4 is arranged in the operation unit 3a, it is possible to avoid an increase in the depth width of the operation unit 3a.

  FIG. 10 is an explanatory diagram illustrating a third example of the operation unit of the heating cooker according to Embodiment 1 of the present invention. In FIG. 10, the transmission unit 4 is arranged between the adjacent operation areas Ao and in front of the partition unit 42. Also in this case, compared to the case where the transmitting unit 4 is provided on the top plate 2, it is possible to prevent the cooking container 99 from hindering the progress of the infrared signal. Further, the distance between the transmission unit 4 and the kitchen table 101 can be made longer than in the case of FIG. Furthermore, in the third example, the number of the transmission units 4 may be smaller than the number of the operation units 31a, 31b, and 31c, and the number of components of the heating cooker 100 can be reduced.

  FIG. 11 is an explanatory diagram illustrating a fourth example of the operation unit of the heating cooker according to Embodiment 1 of the present invention. In the example shown in FIG. 11, the partitioning section 42 is not provided on the operation surface, and the transmission section 4 is provided between the adjacent operation sections 31a. Thereby, the transmitting unit 4 functions as the partition unit 42, and the degree of freedom of the position where the transmitting unit 4 is installed in the depth direction (the direction of the arrow Y) increases. In any of the positions of the transmission unit 4 exemplified so far, the operation area Ao is not provided on the back side of the transmission unit 4, so that when the user operates the operation unit 3, It is possible to prevent the infrared signal from being interrupted by the finger passing above.

  FIG. 12 is an explanatory diagram illustrating a fifth example of the operation unit of the heating cooker according to Embodiment 1 of the present invention. FIG. 13 is an explanatory diagram schematically showing a path of an infrared signal in the fifth example of the operation unit of the heating cooker according to Embodiment 1 of the present invention. In the fifth example, the transmission unit 4 is provided on a surface 3f of the operation unit 3 on the user side. The direction in which the transmitting unit 4 irradiates the infrared signal P2 is set obliquely upward with a direction component y1 away from the cooking device 100 in the depth direction (arrow Y direction) and an upward direction component z1.

  That is, the transmission unit 4 provided in the operation unit 3a is provided on the front surface of the operation unit 3a and transmits the infrared signal forward. On the other hand, the transmission unit 4 provided in the operation unit 3b is provided on the rear surface of the operation unit 3b, and transmits an infrared signal toward the rear.

  FIG. 13 shows a case where the user operates the kitchen-side operation unit 3a to cook. The infrared signal P2 transmitted from the transmitter 4 so as to go obliquely upward from the front side from the surface 3f on the user side of the operation unit 3a is partially reflected by the arm or body of the user H, and is obliquely upward from the rear. Proceed to. After that, the infrared signal P <b> 2 heading obliquely upward on the rear side reaches a receiving unit 304 provided below the range hood 300 and is received by the receiving unit 304. The remaining portion of the infrared signal P2 hits a wall or the like (not shown) further in front of the user H, and is scattered and attenuated. Note that the direction in which the transmitting unit 4 emits the infrared signal P2 may be perpendicular to the front surface 101c and the rear surface 101d of the kitchen table 101 and include a direction component y1 directed to the outside of the kitchen table 101. Even if the direction in which the infrared signal P2 is irradiated does not include the upward direction component z1 but includes only the direction component y1, the transmitted infrared signal P is reflected by the user H and received. The unit 304 can be reached. The infrared signal P2 may include a downward component.

  By the way, the infrared signal transmitted from the transmitting unit 4 to the receiving unit 304 cannot be transmitted through the cooking container 99 when the cooking container 99 or the like is installed in the transmitting direction. May not be able to receive. In general, in the case of an infrared LED or the like, since infrared rays are radiated radially, the infrared rays are reflected by the user H or a wall or the like, and a part thereof changes direction and proceeds. For this reason, in the above-described fifth example, the receiving unit 304 is configured to receive the infrared signal P2 reflected by the user H without directing the irradiation direction of the infrared signal P2 to the receiving unit 304.

  As described above, according to the cooking device 100 of the first embodiment, since the transmitting unit 4 is provided in the pull-out type operation unit 3, compared to the case where the transmitting unit 4 is provided below the top plate as in the related art. It is possible to prevent the infrared signal from being blocked by the cooking container 99 or the like. As a result, the amount of infrared rays reaching the range hood 300 can be secured to a certain value or more, and the range hood 300 can be stably linked to the operation state of the cooking device 100.

  Further, when the transmitting unit is arranged near the heating unit as in the related art, cooling is performed by a fan or the like in the main unit, so that noise increases. On the other hand, according to the heating cooker 100 of the first embodiment, the transmitting unit 4 is provided in the operation unit 3 and is cooled by the outside air. Therefore, the drive of the fan for cooling the transmission unit 4 can be reduced, and cost reduction and noise reduction can be realized.

The second embodiment is different from the first embodiment in that the heating cooker 100 includes the open / close detection device 6. In the second embodiment, items that are not particularly described are the same as those in the first embodiment, and the same functions and configurations are described using the same reference numerals.

  The open / close detection device 6 detects that the operation units 3a and 3b have been pulled out from the operation unit storage unit 101b of the kitchen table 101. The opening / closing detection device 6 includes, for example, a detection unit 62 such as a magnet and a detection unit 61 such as a reed switch for detecting magnetism. The detected part 62 is installed at a lower part on the back side of the operation units 3a and 3b, and the detection part 61 is connected to the detected part 62 on the inner wall of the operation unit storage part 101b in a state where the operation units 3a and 3b are stored. They are provided at opposing positions. The switch state of the detection unit 61 switches between a case where the distance between the detection unit 61 and the detected unit 62 is within a certain range and a case where the distance exceeds the certain range.

  When the operation units 3a and 3b are stored in the kitchen table 101, that is, when the operation units 3a and 3b are closed, the detection unit 61 and the detected unit 62 are close to each other, and the switch state of the detection unit 61 is OFF. Become. When the operation units 3a and 3b are pulled out of the kitchen table 101, that is, when the operation units 3a and 3b are opened, the distance between the detection unit 61 and the detected unit 62 is increased.
