  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a perspective view of a ventilating fan device that is interlocked with the heating cooker according to the first embodiment of the present invention. FIG. 2 is a partial perspective view of a ventilating fan device that is interlocked with the heating cooker according to the first embodiment of the present invention.

  In FIG. 1, a top plate 3 made of crystallized glass and having a thickness of 4 mm can be attached to and detached from a top surface 2 of a substantially rectangular parallelepiped main body 1. A heating coil 4 is disposed in the main body 1 below the top plate 3 so as to be positioned on the left and right.

  Below the left heating coil 4, a grill 5 for grilling fish and the like is disposed, and a door 6 for taking in and out the food from the front of the main body 1 is provided.

  A control circuit 7 for supplying and controlling electric power to the heating coil 4 is disposed below the right heating coil 4. An operation unit 8 that can be freely opened and closed is arranged in front of the main body 1 in front of the control circuit 7. The cooking of the grill 5 is operated by the operation unit 8.

  A switch 9 for operating the heating coil 4 is disposed in the vicinity of the front end of the heating plate 4 of the top plate 3. The switch 9 has a configuration of an electrostatic touch type that operates by static electricity through a top plate 3 made of glass.

  An air inlet 10 is arranged at a position on the right rear side of the main body 1 and behind the heating coil 4. Since the air inlet 10 is located behind the top plate 3, it is constituted by a member different from the top plate 3. Indoor air is sucked from the air inlet 10 to cool the control circuit 7 and the heating coil 4. An intake cooling fan 11 is provided near the lower portion of the intake port 10.

  The intake port 10 is located on the right side of the main body 1 because the control circuit 7 is built in the right side of the main body 1. Since the cooling fan 11 is disposed immediately below the intake port 10, the air is sucked in from the shortest distance from the intake port 10, and the control circuit 7 is disposed in front of the cooling fan 11. Cooling air can be blown.

An exhaust port 12 is disposed at the rear left side of the main body 1 and at a position behind the heating coil 4. A grill 5 is disposed on the left side of the main body 1. From the exhaust port 12, air that is sucked from the intake port 10 and cools the control circuit 7 and the heating coil 4 in the main body 1 is exhausted. Since the exhaust port 12 is located behind the top plate 3, the exhaust port 12 is configured as a separate member from the top plate 3.

  A cover 13 is placed on the intake port 10 and the exhaust port 12. The cover 13 is fitted into the intake port 10 and the exhaust port 12 to determine the position. Infrared transmitters 14 are respectively provided in the main body 1 below the intake port 10 and the exhaust port 12.

  The infrared transmitter 14 emits an infrared signal, which is a drive signal for driving the ventilation fan device, from the inside of the main body 1 through the through hole 15 of the cover 13 placed at the intake port 10 and the exhaust port 12. The position of the infrared transmitter 14 is positioned behind the heating coil 4 in the main body 1.

  A ventilation fan device 16 is provided above the main body 1. The ventilation fan device 16 is generally covered with a canopy 17 formed by pressing a surface-treated steel plate. The steel plate is ferromagnetic. The ventilation fan device 16 is arranged inside the canopy 17 and exhausts the smoke guided and collected by the canopy 17 to the outside. The ventilation fan device 16 is provided with a receiving device 18 that receives an infrared signal transmitted from the infrared transmitting device 14 described above.

  The position of the receiving device 18 is located on the front side of the ventilation fan device 16. The receiving directivity of the receiving device 18 receives infrared signals from the front of the ventilation fan device 16 but cannot direct infrared signals from the rear of the ventilation fan device 16.

  The infrared rays transmitted from the infrared transmitter 14 are radiated at an angle of about 100 degrees above the main body 1, but the receiver 18 receives an infrared signal that travels straight from the infrared transmitter 14 because the main body of the ventilation fan is an obstruction. Cannot receive.

  A reflector 19 is fixed to a canopy 17 made of a steel plate with a magnet 20. The canopy 17 is formed of a steel plate that is a ferromagnetic material. The reflective material 19 is formed by pressing a stainless steel plate or the like.

  The reflecting surface 21 provided on the reflecting material 19 is processed as close to a mirror surface as possible so as to easily reflect light. The reflective surface 21 is formed by processing a stainless steel plate forming the reflective material 19 into a flat surface. A magnet 20 is fixed to the reflector 19, and the magnet 20 is attracted by a magnetic force to the canopy 17 formed of a steel plate that is a ferromagnetic material.

  That is, the reflector 19 is fixed to the canopy 17 which is a part of the ventilation fan device 16 formed of a ferromagnetic material by the magnet 20. The canopy 17 need not be specially processed. The reflector 19 is only fixed to the canopy 17 by the magnetic force of the magnet 20. The reflecting material 19 is fixed to the front portion of the canopy 17, and the reflecting surface 21 faces the intake port 10 and the exhaust port 12 at the rear of the main body 1.

  Infrared signals transmitted from the back of the main body 1 are diffused within the range of the radiation angle. A part proceeds in the forward direction of the main body 1. A part of the infrared signal traveling from the rear to the front of the main body 1 is reflected by the reflecting surface 21 of the reflector 19 attached to the canopy 17 and proceeds from the front of the main body 1 toward the rear.

  The infrared signal is received by the receiver 18 attached to the ventilation fan device 16 facing forward, and the signal of the infrared transmitter 14 is received by the receiver 18. The receiver 18 is located in front of the canopy 17, and this position is located in front of the center of the heating coil 4.

There is no handle 23 of the pan 22 or the hand or head of the cook in the path of the infrared signal, and an infrared signal having a straight traveling property can be reliably transmitted to the receiving device 18.

  Conventionally, since the infrared transmitter 14 is disposed at the front of the main body 1, that is, below the top plate 3 on the near side of the heating coil 4, the receiver 18 is almost always provided in front of the ventilation fan device 16. .

  In particular, it is generally located before the center of the heating coil 4. Considering compatibility with conventional models, the receiving device 18 is preferably arranged on the front side of the ventilation fan device 16. When the infrared transmitter 14 is a cooking device located in front of the main body 1, that is, in front of the heating coil 4, it reaches the receiving device 18 without being reflected by the reflecting material 19.

  Consider replacing the main body 1 of the heating cooker with a heating cooker having an infrared transmission device 14 behind the center of the heating coil 4 from a heating cooker with an infrared transmission device 14 in front of the heating coil 4 center. Then, the receiving device 18 is preferably arranged in front of the ventilation fan device 16. By doing so, it can be arbitrarily selected whether the infrared transmitter 14 is provided in front of the main body 1 of the heating cooker or in the rear of the main body 1.

  The operation and action of the ventilating fan device interlocked with the heating cooker configured as described above will be described below.

  First, the pan 22 is placed on the top 3. The switch 9 is operated to pass a high frequency current from the control circuit 8 to the heating coil 4. An eddy current is generated at the bottom of the pan 22 by the magnetic flux generated from the heating coil 4 to generate heat. The food in the pot 22 generates steam with heating. Hot air that has cooled the control circuit 7 and the heating coil 4 is discharged from the exhaust port 12 of the main body 1.

  The operation unit 8 is operated to transmit an infrared signal for operating the ventilation fan device 16 from the infrared transmission device 14.

  The infrared rays transmitted upward from the infrared transmission device 14 are dissipated above the main body 1 through the through holes 15 of the cover 13. Part of the diffused infrared light travels straight toward the front of the main body 1. Infrared rays directed obliquely upward enter the reflecting surface 21 of the reflector 19 from the rear side of the main body 1 and are reflected in the direction from the front side of the main body 1 to the rear side.

  The infrared rays reflected by the reflecting material 19 go straight in the direction from the front to the rear of the main body 1 and reach the receiving device 18. The ventilation fan device 16 is activated by the infrared signal received by the receiving device 18. Thus, when steam etc. generate | occur | produce from the pan 22, the ventilation fan apparatus 16 can be operated by operating the operation part 8. FIG.

  For a while after cooking is completed, the ventilation fan device 16 is operated to ventilate the room, but when the ventilation is finished, the operation unit 8 is operated and an infrared signal as a stop signal is transmitted from the infrared transmission device 14. Then, the signal is reflected by the reflecting material 19 to guide the signal to the receiving device 18. The ventilation device 16 stops when the receiving device 18 receives the stop signal.

  The infrared signal from the infrared transmission device 14 can be generated by a direct operation from the operation unit 8, or the control circuit 7 can automatically issue an operation signal to activate or deactivate the ventilation fan device 16. As long as signals can be transmitted and received between the infrared transmitter 14 and the receiver 18, the signal source may be a person or the control circuit 7.

DETAILED DESCRIPTION Reference in the first embodiment of the present invention will be described with reference to FIG.

Figure 3 is a perspective view of a ventilating fan device in conjunction with a cooker in the present first reference.

  Except for the reflecting material 30, the receiving device 31, and the reflecting surface 32, the same reference numerals as those in Embodiment 1 have the same shape and the same function.

  In FIG. 3, the reflector 30 is fixed to the rear of the canopy 17. The receiving device 31 is disposed behind the ventilation fan device 16 and is configured to receive a signal from the rear. The position of the receiving device 31 is located behind the ventilation fan device 16.

  The receiving directivity of the receiving device 31 is an orientation that receives an infrared signal from the rear side of the ventilation fan device 16 but cannot receive an infrared signal from the front side of the ventilation fan device 16. The positional relationship between the receiving device 18 and the reflector 19 of the first embodiment is arranged behind the ventilation fan device 16.

  Including the above contents, the same reference numerals and names as those of the first embodiment have the same functions as those of the first embodiment, and thus the description thereof is omitted.

  The operation and action of the ventilating fan device interlocked with the heating cooker configured as described above will be described below.

  First, the pan 22 is placed on the top 3. The switch 9 is operated to pass a high frequency current from the control circuit 7 to the heating coil 4. An eddy current is generated at the bottom of the pan 22 by the magnetic flux generated from the heating coil 4 to generate heat. The food in the pot 22 generates steam with heating. Hot air that has cooled the control circuit 7 and the heating coil 4 is discharged from the exhaust port 12 of the main body 1. The operation unit 8 is operated to transmit an infrared signal for operating the ventilation fan device 16 from the infrared transmission device 14.

  The infrared rays transmitted upward from the infrared transmission device 14 are dissipated above the main body 1 through the through holes 15 of the cover 13. Part of the diffused infrared light travels straight upward toward the top of the main body 1. The infrared signal traveling straight upward is directly incident on the receiving device 31, or the infrared signal reflected by the reflecting material 30 is incident on the receiving device 31, in any case, the infrared signal reaches the receiving device 31. The ventilation fan device 16 is activated by the infrared signal received by the receiving device 31.

  Thus, when steam etc. generate | occur | produce from the pan 22, the ventilation fan apparatus 16 can be operated by operating the operation part 8. FIG.

  For a while after cooking is completed, the ventilation fan device 16 is operated to ventilate the room, but when the ventilation is finished, the operation unit 8 is operated and an infrared signal as a stop signal is transmitted from the infrared transmission device 14. Then, the signal is reflected by the reflecting material 30 to guide the signal to the receiving device 31. The receiving device 31 receives the stop signal and the ventilation fan device 16 stops.

  The infrared signal from the infrared transmitter 14 can be generated by a direct operation from the operation unit 8 or can be automatically sent from the control circuit 7 to activate or deactivate the ventilation fan device 16. As long as signals can be transmitted and received between the infrared transmitter 14 and the receiver 31, the signal source may be a person or the control circuit 7.

When the main body 1 breaks down or is replaced with an old one, if the infrared transmission device 14 is behind the heating coil 4 of the main body 1, infrared transmission / reception is performed as described above. In the case where the product placed on the main body 1 is replaced, the infrared transmission device 14 is positioned in front of the center of the heating coil 4 of the main body 1, so that the transmitted infrared signal is radiated above the main body 1 and a part thereof is the main body 1. Proceed backwards.

  The light is reflected from the reflecting surface 32 of the reflecting material 30 in the direction from the front to the back of the main body 1, and after being reflected by the reflecting surface 32, it proceeds from the back to the front of the main body 1. Then, the light enters the receiving device 31 and the signal reaches the receiving device 31.

  In this manner, the ventilation fan device 16 can be operated by operating the operation unit 8. When the ventilation fan device 16 is stopped, the same signal is transmitted along the transmission path.

  That is, even if the position of the infrared transmitter 14 is located in front of the main body 1 or in the rear of the main body 1, the receiving device 31 directly receives the light or reflects on the reflecting surface 32 of the reflecting material 30 and is reflected on the receiving device 31. The infrared signal reaches the receiving device 31 by either method.

  Operations and operations other than those described above are the same operations and operations as in the first embodiment.

  In the first embodiment, the reflective material 19 is formed of a stainless steel plate, but may be formed of any material as long as it has heat resistance and durability as long as it is a material that reflects infrared rays or is subjected to surface treatment. Any material that reflects infrared rays may be used.

  Moreover, although the method of fixing the reflecting material 19 to the canopy 17 is a method of fixing the reflecting material 19 provided with the magnet 20 to the canopy 17 formed of a steel plate by a magnetic force, it may be fixed with an adhesive or a double-sided tape. .

Although the reflector 30 and the receiver 31 in the first reference is arranged behind the center of the heating coil 4 behind the ventilation fan unit 16, the reflector reflects the infrared signal emitted from below the ventilating fan 16 19 If it is arrange | positioned in the vicinity, the receiver 18 and the reflecting material 19 may be arrange | positioned in the arbitrary positions of the canopy 17. FIG.

  The infrared signal may arrive at the receiving device 18 by either an incident after reflecting an infrared signal radiated from an arbitrary position of the main body 1 by the reflecting material 19 or directly entering the receiving device 18.

  Moreover, although the infrared rays transmitter 14 was radiated | emitted from the through-hole 15 of the cover 13 without passing through the top plate 3 formed with the heat-resistant glass, it is not interrupted | blocked by the pot 22 near the outer periphery of the main body 1, or a person's hand and head. An infrared signal may be emitted from the position.

Furthermore, in Embodiment 1 and Reference Embodiment 1 , an infrared signal is transmitted from the main body 1 to the ventilation fan device 16, but conversely, an infrared signal is transmitted from the ventilation fan device 16 toward the main body 1, and a part of the infrared signal is directly transmitted to the main body 1. The light may be emitted in the direction, and a part of the light may be reflected by the reflective members 19 and 30 and then directed toward the main body 1.

  As described above, the ventilating fan device according to the present invention can reliably transmit a signal to the receiving device by reflecting the infrared rays by the reflecting material, and the heating cooker linked to the ventilating fan device is an induction heating cooker, a gas It can be applied to a cooking device.
