Description

  The present invention relates to a ventilation control system.

  A method for efficiently exhausting generated smoke and hot air by estimating the amount of smoke and hot air generated by the use of cooking equipment and controlling the rotation amount of the ventilation fan according to the estimated amount is known. . For example, Patent Document 1 discloses a range hood having an air volume adjustment function that adjusts the ventilation air volume in stages according to the operation of a cooking device and the progress of cooking.

JP2012-083009A

  However, realistically, other ventilation devices and air conditioning equipment are installed in the room besides the range hood. The range hood disclosed in Patent Document 1 does not consider the interaction with other ventilators and air conditioners. For this reason, smoke, hot air, and odor may diffuse into the room due to their interaction, or exhaust may be delayed.

  For example, if a face-to-face kitchen with a range hood and a living room are installed, and a ventilation opening is provided on the opposite side of the living room when viewed from the kitchen's range hood, when the range hood is activated, the ventilation opening is directed to the living room. The air can flow. This air flow becomes stronger when the number of rotations of the ventilation fan included in the range hood is increased. Therefore, if the rotation speed of the ventilation fan is increased when the amount of smoke or hot air generated by the use of cooking equipment is large, the exhaust gas such as smoke, hot air, and odors is exhausted by the strong flow of air supplied from the ventilation openings. It spreads to the side, which in turn makes the user uncomfortable.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a ventilation control system that can efficiently exhaust an exhaust target generated by heating of a heat source and suppress discomfort felt by a user. And

In order to achieve the above object, the ventilation control system of the present invention comprises:
An exhaust fan for cooking that exhausts an exhaust target generated by heating of a heat source included in the cooking device from the inside of the ventilation target space provided with the cooking device;
An exhaust assist mechanism that assists the exhaust of the exhaust target by the cooking fan;
Equipment with a blowing function;
A ventilation control device that is electrically connected to the cooking fan, the exhaust assist mechanism, and the equipment, and that controls the cooking vent fan, the exhaust assist mechanism, and the equipment;
The ventilation control device weakens or stops the blowing by the equipment when the cooking device operates.

  In the present invention, the ventilation control device weakens or stops the blowing by the equipment when the cooking device operates. ADVANTAGE OF THE INVENTION According to this invention, the exhaust object which generate | occur | produces by the heating of a heat source can be exhausted efficiently, and the discomfort which a user feels can be suppressed.

When the atmospheric pressure in the room is lower than the external atmospheric pressure, air is supplied into the room from the ventilation opening 210, and when the indoor atmospheric pressure is higher than the external atmospheric pressure, the indoor air passes through the ventilation opening 210. Exhausted outside.

The cooking device 220 is a cooking device constituted by an IH (Induction Heating) cooking heater or the like. The cooking device 220 creates a ventilation index indicating the state of occurrence of the exhaust target causing the ventilation, and transmits the ventilation index to the ventilation control device 100.

  The range hood 230 is a ventilation device that is disposed directly above the cooking device 220 and includes a ventilation duct and a ventilation fan (a cooking fan). The range hood 230 mainly sucks smoke and water vapor generated by cooking and discharges them to the outside. The range hood 230 operates according to instruction data from the ventilation control device 100.

  The air supply / exhaust fan 240 is a fan provided on the wall. For example, when the air supply / exhaust fan 240 rotates in the forward direction, external air is supplied into the room, and when the air supply / exhaust fan 240 rotates in the reverse direction, the internal air is discharged outside the room. To do. The air supply / exhaust fan 240 operates in accordance with instruction data from the ventilation control device 100.

  The air conditioner 250 is a so-called indoor unit of an air conditioner, and performs air conditioning by sucking air from a suction port, performing processing such as heating, cooling, and dehumidification, and blowing air from a blower port. The air conditioner 250 operates according to the instruction data from the ventilation control device 100, and can change the wind direction and air volume of the blown-out wind.

The ventilation control device 100 exhibits various functions by having the above-described configuration. With reference to FIG. 2, the functional structure of the ventilation control apparatus 100 is demonstrated.
The ventilation control device 100 accepts an instruction from the user or presents information to the user, a communication interface 120 that communicates with the equipment 200, and the equipment 200 according to the instruction accepted by the user interface 110. And a ventilation control processing unit 140 for controlling the facility device 200 according to the ventilation operation set by the setting processing unit 130.

  The user interface 110 is realized mainly by the input unit 14 and the output unit 15. The user interface 110 outputs, to the setting processing unit 130, information indicating the configuration of the room (ventilation target space) input by the user and the arrangement of the equipment 200 in the room, information indicating the function of the equipment 200, and the like.

The communication interface 120 is mainly realized by the communication unit 16. The communication interface 120 receives thermal power data indicating the degree of thermal power of the cooking device 220 and outputs it to the ventilation control processing unit 140.
In addition, the communication interface 120 acquires instruction data for the control target range hood 230, the supply / exhaust fan 240, and the air conditioning device 250 from the ventilation control processing unit 140, and transmits the acquired instruction data to the control target device.

  The setting processing unit 130 is realized mainly by the cooperation of the control unit 11, the main storage unit 12, and the auxiliary storage unit 13, and determines the control content. The setting processing unit 130 includes an arrangement information acquisition unit 131 that acquires arrangement information indicating the configuration of the room (the space to be ventilated) and the arrangement of the equipment 200 installed in the room, and the equipment installed in the room. A facility information acquisition unit 132 that acquires information indicating the function of the device 200; a determination unit 133 that determines the operation of the control target facility device 200; and a ventilation operation setting unit 134 that sets the operation of the control target facility device 200. ,have.

The arrangement information acquisition unit 131 acquires arrangement information that is received by the user interface 110 and indicates the configuration (room layout) of the room (the ventilation target space), the position of each facility device 200 in the room, and the like. The information indicating the room configuration includes information such as the size and shape of the room, for example. The information indicating the position of each facility device 200 includes information indicating each arrangement position in the room.
The arrangement information acquisition unit 131 outputs the acquired arrangement information to the facility information acquisition unit 132.

The facility information acquisition unit 132 acquires the layout information output by the layout information acquisition unit 131 and the function information indicating the function of the facility device 200 received by the user interface 110. As shown in FIG. 3, the function of the facility device 200 indicates the operation, thermal power, air volume, wind direction, and the like of the facility device 200.
In the example of FIG. 3, the cooking device 220 can change its heating power into three levels of strong, medium, and weak, and the energy consumption when “strong”, “medium”, and “weak” is, for example, 3 kW, 2 kW and 1 kW. Further, the range hood 230 can change its exhaust capacity into three levels of strong, medium, and weak, and the exhaust capacity at “strong”, “medium”, and “weak” is, for example, 600 m ³ / h and 370 m, respectively. ³ / h, 170 m ³ / h. Since the vent 210 does not perform active ventilation but performs passive ventilation, it is represented by the effective opening size of the vent.
The facility information acquisition unit 132 maps the function information of each facility device 200 to the facility device 200 indicated by the placement information, and outputs the mapped information to the determination unit 133.

The determination unit 133 stores in advance a plurality of operation algorithms corresponding to a scene (combination of a room configuration, the arrangement of the equipment 200, and a function of the equipment 200).
The determination unit 133 selects a scene similar to the scene indicated by the information obtained from the facility information acquisition unit 132 from the preset scenes, and uses the operation algorithm corresponding to the selected scene to increase the heating power of the cooking device 220. The overall ventilation operation of the equipment 200 to be controlled is determined.
For example, information obtained from the facility information acquisition unit 132 may be used as a method in which the determination unit 133 selects a scene similar to the scene indicated by the information obtained from the facility information acquisition unit 132 from preset scenes. There is a method of selecting the smallest sum of squares of the difference between the scene evaluation value shown and the scene reference value stored in the determination unit 133 in advance.
Further, regarding the operation of the determination unit 133, a function of simulating the air flow in the room and selecting a combination of good results while changing the combination of parameters may be provided. By simulating, it is possible to find the optimal action that brings out the effect of improving discomfort more suited to the scene. However, if simulation is performed without back data, there is a problem that it takes too much time to actually start the operation. Therefore, it is most efficient and highly effective to advance the simulation while operating with the stored operation algorithm described above, perform optimization, and operate while performing fine correction of the operation.

  As shown in FIG. 4, the ventilation operation setting unit 134 associates the thermal power data indicating the thermal power of the cooking device 220 with the control information indicating the ventilation operation determined by the determination unit 133 based on the selected operation algorithm. Set in the control table.

  The ventilation control processing unit 140 is realized mainly by the cooperation of the control unit 11, the main storage unit 12, and the auxiliary storage unit 13, and according to the information in the control table, the heating power of the heating cooking appliance 220 Accordingly, the control target equipment 200 is controlled. The ventilation control processing unit 140 includes a ventilation index acquisition unit 141 that acquires thermal power data indicating the thermal power of the cooking device 220, a control information acquisition unit 142 that acquires control information corresponding to the thermal power data from the control table, and the acquired control And a ventilation control unit 143 that controls the equipment 200 to be controlled according to the information.

The ventilation index acquisition unit 141 acquires the thermal power data received by the communication interface 120 from the cooking device 220.
The control information acquisition unit 142 acquires control information corresponding to the thermal power data acquired by the ventilation index acquisition unit 141 from the control table.
The ventilation control unit 143 controls the control target equipment 200 based on the control information acquired by the ventilation operation setting unit 134. That is, the ventilation control unit 143 performs cooking so that the operation of the cooking fan (range hood 230) and the equipment device 200 corresponding to the ventilation index (thermal power data) acquired by the ventilation index acquisition unit 141 is performed. The hour ventilator and the equipment 200 are controlled to ventilate.

  Next, operation | movement of the ventilation system 1 which has the said structure is demonstrated with reference to FIGS. 5-7.

  The ventilation system 1 not only links the heating power of the cooking device 220 and the operation of the range hood 230, but also comprehensively controls a plurality of facility devices 200 set in the room. Before operating the ventilation system 1 to ventilate the room, the user sets which equipment device 200 is to be operated and ventilated according to the heating power of the cooking device 220. The setting may be performed once when the ventilation system 1 is installed.

Hereinafter, the setting process and the ventilation control process will be described separately for each scene.
(Setting process)
At the time of installation of equipment, the user operates the input unit 14 of the ventilation control device 100 to activate the setting process shown in FIG. 5 and defines the individual rooms to be ventilated (for example, the ventilation target. Information indicating the shape and size of the room, etc.) and arrangement information including information indicating the arrangement of the equipment 200 in the room are input from the input unit 14. The arrangement information acquisition unit 131 acquires arrangement information input by the user via the user interface 110 (step S101).

Subsequently, the user inputs function information of each equipment device 200 arranged in the room. Further, the user inputs priority position information indicating which position in the ventilation target space is prioritized to keep air clean.
The facility information acquisition unit 132 acquires the input function information and priority position information via the user interface 110 (step S102).

As described above, the user may operate the user interface 110 and input arrangement information and the like. However, there is a possibility that the user may take unnecessary trouble. Therefore, the input is performed by the installer of the indoor equipment 200 and may be set so that the user cannot easily change the setting.
In particular, with regard to device information, contractors who construct homes, including housing manufacturers and renovation manufacturers, have more knowledge, and there is a risk that malfunctions may occur due to the fact that the user can set details. In other words, since the installation status of the equipment depends on the form of the house and it is difficult to change easily, the items that can be set by the user in terms of labor and operational efficiency are strong air volume, medium , Weak, power ON / OFF, simple settings to be input when portable blower equipment such as air purifiers and fans are installed, and detailed settings should be done automatically or use preset ones good.

  Subsequently, the determination unit 133 selects an operation algorithm based on the arrangement information and the function information. As shown in the control table of FIG. 4, in each case where the heating power of the cooking device 220 is strong / medium / weak, the air volume / wind direction of the equipment 220 having the smallest amount of smoke or hot air intrusion at the priority position is shown. The combination is determined as the ventilation operation of the control target equipment 200 (step S103).

  The basic control direction and concept for achieving suppression of odor diffusion in the living room will be described. Control is performed in the direction and concept described below. Conditioning is performed for each operation of the device shown in FIG. 3, and a base of an operation algorithm is created based on this.

<About "Heating">
About heating, it detects with the input amount and timing to an apparatus, a temperature sensor, an odor sensor, and a smoke sensor. Although errors occur due to moisture contained in the food material, the amount of exhaust gas tends to increase as the heating temperature increases, and “exhaust” and “supply” are increased in accordance with the heating temperature. Increasing “exhaust” and “supply air” in accordance with the heating temperature is necessary to treat more exhaust gas, and generally increases the air volume of the range hood 230 to “exhaust”. However, problems such as leaks that cannot be processed by the range hood 230, reduced air-conditioning effect due to increased ventilation rate, and increased noise due to increased fan speed, cause exhaust by the range hood 230. It is good to support by the equipment 200, suppress diffusion, and prevent the air volume of the range hood 230 from being increased as much as possible.

<About "Exhaust">
Exhaust is basically performed only by the range hood 230. When the exhaust gas increases, the amount of supply air increases accordingly, so that outside air is taken in more than necessary, and the indoor air is disturbed.
Exhaust other than the range hood 230 is primarily intended to provide support in the event that an object becomes scorched and the exhaust gas increases more than expected. In addition, in the case of cooking grilled meat or the like, there may be cases where cooking is performed in the living room. For example, as shown in FIGS. 6A-6C, in a room where the equipment 200 is installed, the supply / exhaust fan 240 functions as an exhaust fan and functions in the same way as the range hood 230 when cooking in the living room L. An operation algorithm may be provided so that it can be performed.

<About "Air Supply">
You may raise the air volume of the air supply / exhaust fan 240 to the air volume close | similar to the range hood 230 so that the air supply from the living L side may become main. By increasing the amount of air supplied from the living room L, it is an object to form an air current from the living room L toward the kitchen K, and to form a defensive air stream that prevents the exhaust gas from going to the living room L side. However, an airflow from the kitchen K to the living room L is also necessary. If the air supply from the living room L is too strong, the exhaust power of the range hood 230 may be exceeded and the exhaust gas may be pushed out toward the kitchen K, and the exhaust gas may flow through the wall on the kitchen K side. Because there is. Therefore, it is necessary to obtain sufficient air supply from the vent 210 to prevent the exhaust gas from being pushed out to the kitchen K side. Balancing the supply air volume between the supply / exhaust fan 240 and the ventilation port 210 is one of the roles of the ventilation system 1. The ventilation control device 100 controls the supply / exhaust amount of the supply / exhaust fan 240 to balance the air volume from the living L side and the air volume from the kitchen K side in the vicinity of the suction port of the range hood 230. The amount of exhaust is approximately the same. Thereby, the leakage of the exhaust gas can be suppressed to an extremely small amount, and the diffusion of the exhaust gas into the living room L can be prevented.

<About "Air Circulation">
Basically, there should be no air circulation. Although the air conditioner 250 circulates air in the present embodiment, the air conditioner 250 is often installed in the living room L. Since the air conditioner 250 performs air suction and discharge at the same time, if the operating air volume is increased, the exhaust gas may be strongly drawn into the living room L side. For this reason, the air volume should be as small as possible and stopped depending on the situation.
On the other hand, when the range hood 230 operates with a large air volume, the temperature change due to the exchange of the outside air and the inside air becomes remarkable, so that it is desirable to operate the air conditioner 250 to make the indoor temperature state comfortable. . Therefore, the air conditioner 250 needs to operate with an air volume that does not impair the air supply operation of the air supply / exhaust fan 240 and the ventilation port 210.
By the way, unless the wind generated by the suction of the air conditioner 250 is dispersed to a wind speed lower than the supply air speed of the supply / exhaust fan 240, the supply air of the supply / exhaust fan 240 may be disturbed to diffuse the exhaust gas. In order not to disturb the airflow even if the air volume by the air conditioner 250 is large, it is preferable to reduce the wind speed by dispersing the exhaust. If the wind speed is high, an attraction such as the Coanda effect occurs and the airflow is easily disturbed. However, if the wind speed is reduced, the airflow disturbance can be minimized. If the wind direction width of the air conditioner 250 can be changed, the wind from the discharge port may be broad (the wind direction width of the wind discharged from the discharge port may be widened). Also in the suction port of the air conditioner 250, if the suction width of the air can be changed, the suction area may be widened and the wind generated by the suction may be dispersed.
In addition, when the air supply air volume of the air supply / exhaust fan 240 is large, the air wind of the living L may be involved and the exhaust gas may be diffused. Here, when the air from the air conditioner 250 is sent to the kitchen K side so as to wrap the air supplied from the air supply / exhaust fan 240, the entrainment air generated by the air supplied from the air supply / exhaust fan 240 is suppressed and diffusion is suppressed. I can do it. In particular, the size of the air supply / exhaust fan 240 is limited, and an air flow that supports the entire range sucked by the range hood 230 cannot be generated. By pointing to the device C, leakage from a wider area can be supported.

An example of determination by the determination unit 133 will be described using the room illustrated in FIGS. 6A to 6C as an example. In this room, there are a kitchen K and a living room L, which are face-to-face kitchens. The ventilation opening 210 is on the ceiling of the kitchen K, the range hood 230 is on the upper part of the cooking device 220, and the air supply and exhaust fan 240 is on the living room L Air conditioners 250 are respectively installed above the living room L on the ceiling. In this example, the priority position A is the hollow portion of the living room L.
When the ventilation port 210 is provided in the kitchen K as in the room of this example, when the range hood 230 is operated, air can flow from the ventilation port 210 toward the kitchen K.

For example, when the heating power of the cooking device 220 is “strong”, the determination unit 133 sets the ventilation air volume of the range hood 230 to “strong” and the supply / exhaust fan 240 “stops” (stop) as shown in FIG. It is assumed that when the air volume of the air conditioner 250 is a combination of “weak” and the wind direction is “down”, it is determined that the amount of smoke entering the hollow portion of the living room L, which is the priority position A, is the smallest. The determination unit 133 determines the combination as a ventilation operation.
In this case, for example, as shown in FIG. 6A, smoke and hot air generated from the cooking utensil C installed in the cooking device 220 circulate around the indoor edge so as not to pass through the priority position A. It is guided to the intake port of the hood 230. When the heating power of the cooking device 220 is “strong”, the air volume of the air conditioning device 250 may be “medium” instead of “weak”.

In addition, for example, when the heating power of the cooking device 220 is “medium”, the determination unit 133 determines that the ventilation air volume of the range hood is “medium” and the air supply air volume of the supply / exhaust fan 240 is as shown in FIG. Assume that it is determined that the amount of penetration into the hollow portion of the living room L, which is the priority position A, is the smallest when the combination is “strong”. The determination unit 133 determines the combination as a ventilation operation.
In this case, for example, as shown in FIG. 6B, the exhaust gas generated from the cooking utensil C installed in the cooking device 220 is directly guided to the intake port of the range hood 230 by the supply of air from the supply / exhaust fan 240. .

Further, for example, when the heating power of the cooking device 220 is “weak”, the determination unit 133 is the priority position A when the ventilation air volume of the range hood is “weak” as shown in FIG. It is assumed that the amount of penetration into the hollow portion of the living L is the smallest. The determination unit 133 determines the combination as a ventilation operation.
In this case, for example, as shown in FIG. 6C, the exhaust gas generated from the cooking utensil C installed in the cooking device 220 is directly sucked into the range hood 230.

  Note that the cleanliness (evaluation value) at the priority position A may change over time. In this case, for example, the time average of the evaluation values may be used as the evaluation value.

  Returning to FIG. 5, when the determining unit 133 determines the ventilation operation of the controlled equipment 200 in step S103 and outputs information indicating the ventilation operation, the ventilation operation setting unit 134 sets these in the control table ( Step S104), the setting process is terminated.

  In addition, you may set arbitrary restrictions on the operation | movement algorithm mentioned above. For example, when the air conditioner 250 is operating, a restriction may be imposed so that the operation of the air conditioner 250 is prioritized. Such a restriction may be customized later by the user.

(Ventilation control processing)
After the setting of the control table, when the cooking device 220 is turned on by the user, the control unit 11 starts the ventilation control process shown in FIG. Here, the ventilation operation after setting the control table will be described with reference to FIG.

When the ventilation control process starts, first, the ventilation index acquisition unit 141 determines whether or not thermal power data (ventilation index) indicating thermal power has been acquired from the cooking device 220 (step S201).
When the ventilation index acquisition unit 141 acquires thermal power data (step S201), the control information acquisition unit 142 refers to the control table and acquires control information set in association with the acquired thermal power data (step S202). ). For example, in the example of FIG. 4, when the thermal power data transmitted from the cooking device 220 indicates that the thermal power is “medium”, the operation indicated by the control information acquired by the control information acquisition unit 142 is The ventilation air volume of the range hood 230 is “medium”, and the air supply air volume of the air supply / exhaust fan 240 is “strong”.

  If the control information acquisition part 142 acquires control information, the ventilation control part 143 will transmit the instruction data which instruct | indicates control of the equipment apparatus 200 to each equipment apparatus 200 according to the acquired control information (step S203). For example, when the acquired control information indicates that the ventilation air volume of the range hood 230 is “medium” and the air supply air volume of the supply / exhaust fan 240 is “strong”, the ventilation control unit 143 passes the communication interface 120. In addition, instruction data indicating an instruction to set the ventilation air volume to “medium” is transmitted to the range hood 230, and instruction data indicating an instruction to set the air supply air volume to “strong” is transmitted to the supply / exhaust fan 240.

When the ventilation control unit 143 transmits instruction data to the controlled equipment 200, the ventilation control process returns to step S201.
Note that the ventilation index acquisition unit 141 is in a standby state until it is determined in step S201 that the ventilation index acquisition unit 141 has acquired new thermal power data.
The range hood 230, the supply / exhaust fan 240, and the air conditioner 250 perform a ventilation operation according to the instruction data from the ventilation control device 100.
When the cooking device 220 is turned off, only the range hood 230 is operated for an arbitrary time, for example, 3 minutes. Alternatively, the flow of the airflow after turning off the cooking device 220 may be simulated, and the equipment may be operated according to the simulation result.

  As described above, according to the present embodiment, the ventilation control device 100 sets the operation of the equipment device 200 to be controlled according to the indoor configuration and the arrangement of the equipment devices 200 therein, It was set as the structure which controls the equipment 200 to be controlled according to the set operation. Thereby, according to the position of the equipment 200 installed indoors, it becomes possible to suppress the discomfort which a user feels by ventilating the air in the room efficiently. In the present embodiment, the operations of all the equipment devices 200 are collectively set according to the functions of all the equipment devices 200. For example, when it is determined that the necessity of ventilation is high based on the ventilation index, the operations of all the equipment devices 200 are collectively set so that a plurality of equipment devices 200 cooperate to efficiently ventilate indoor air. Is done. For this reason, according to this Embodiment, it becomes possible to further suppress the discomfort felt by the user.

(Embodiment 2)
In the ventilation system 1 according to the first embodiment, the determination unit 133 determines the combination of the air volume and the wind direction of the equipment 200 that has the smallest amount of smoke or hot air entering the priority position (for example, the hollow portion of the living room). It was determined as a combination of actions to use at times. Therefore, the ventilation system 1 controls in the same manner whether or not there is a person at the priority position.
In the second embodiment, as shown in FIG. 8, a human sensor 300 is provided in the system so that the content of ventilation control is different depending on whether or not there is a person in the living room. Hereinafter, the ventilation system 2 and method according to Embodiment 2 will be described in detail with reference to the drawings. In addition, about the structure which is the same as that of Embodiment 1, or equivalent, while using an equivalent code | symbol, the description is abbreviate | omitted or simplified.

The human sensor 300 includes, for example, a PIR (Passive Infrared) sensor, a Doppler module type sensor, and a CMOS (Complementary MOSFET) image sensor. The human sensor 300 is installed, for example, on the living side of the room and detects the presence of a person in the living room.
It should be noted that the human sensor 300 can be replaced with an equipment mounted on a device incorporated in the ventilation system 2 as the facility device 200. In particular, many air conditioners 250 are pre-installed. Since the air conditioner 250 is often installed above the room, in this case, a person is detected from above. In addition, when a module equipped with the human sensor 300 is installed at an intermediate height in the room such as on a desk, there is an advantage that it is easy to detect a space where the living room L is fixed and an advantage that it is easy to carry. On the other hand, when the module is left behind, furniture or the like may become an obstacle, and erroneous detection may occur. For example, it becomes difficult to detect human movements outside the living room L. Therefore, it is more effective that the human sensor 300 is installed above the room from the viewpoint of versatility.
In addition, by using the human sensor 300 mounted on the air conditioner 250 or the like, the space occupied by the separately prepared human sensor 300 can be omitted, and it is not necessary to prepare a module on which the human sensor 300 is separately mounted. This saves the user trouble.

  Further, the position of a person may be specified using a GPS (Global Positioning System) such as a mobile phone. For example, since a mobile phone is often moved even when it is in the living room or is often placed in a room where it is present, it is useful for grasping the position of a person. However, GPS can only obtain very rough position information by itself, and there may be cases where GPS radio waves are obstructed indoors. Therefore, high accuracy may be achieved by using the GPS possessed by the facility device 200 and the GPS possessed by other home appliances, OA devices, etc., and operating these as fixed stations.

The determination unit 133 stores a plurality of operation algorithms corresponding to scenes in advance.
The determination unit 133 selects a scene similar to the scene indicated by the information obtained from the facility information acquisition unit 132 from the preset scenes, and uses the operation algorithm corresponding to the selected scene to determine the facility device 200 to be controlled. Determine overall ventilation behavior.

  The determination unit 133 determines the combination of the air volume and the wind direction of the facility device 200 with the smallest amount of smoke or hot air entering the priority position A as the ventilation operation when the human sensor 300 detects that there is a person in the living room L. . In addition, the determination unit 133 exhausts the generated heat amount or the airflow more than a reference value (for example, 80%), and the combination of the air volume and the wind direction of the equipment device 200 having the smallest sum of the power consumption amounts of the controlled equipment devices 200. Is determined as a ventilation operation when the human sensor 300 does not detect the presence of a person in the living room L.

For example, when the heating power of the cooking device 220 is “strong”, it is assumed that the determining unit 133 selects an optimal operation algorithm. As a result, as shown in FIG. 9, the combination of the range hood 230 with the ventilation airflow “strong”, the air supply / exhaust fan 240 “stopped”, the air conditioner 250 with the airflow “weak”, and the wind direction “down”. In this case, when the amount of smoke entering the hollow portion of the living room is the smallest, the determination unit 133 determines the combination as a ventilation operation when the human sensor 300 detects the presence of a person.
In this case, as shown in FIG. 10A, smoke and hot air generated from the cooking utensil C installed in the cooking device 220 circulate around the indoor edge so as not to pass through the priority position A, and the range hood 230. It is guided to the intake port of. When the heating power of the cooking device 220 is “strong” and the presence of a person is detected, the air volume of the air conditioning device 250 may be “strong”.

Further, for example, as a result of selecting the operation algorithm, as shown in FIG. 9, the ventilation air volume of the range hood 230 is “medium”, the supply / exhaust fan 240 is “strong”, the air volume of the air conditioner 250 is “medium”, and the wind direction is “medium” When the amount of generated heat (or airflow) can be exhausted above the reference value and the sum of the power consumption of the equipment 200 is the smallest, the determining unit 133 determines the combination as a human sensor. 300 is determined as a ventilation operation when the presence of a person is not detected.
In this case, as shown in FIG. 10B, the smoke and hot air generated from the cooking utensil C installed in the cooking device 220 are directly drawn into the range hood 230 by the air sent from the air supply / exhaust fan 240 and the air conditioning device 250. It is guided to the mouth. When the heating power of the cooking device 220 is “strong” and the presence of a person is not detected, the air volume of the air conditioning device 250 may be “strong”.

  In the air conditioner 250, when a person is present in the living room L, directing the air direction of the air conditioner 250 toward the range hood 230 may give the person a feeling of airflow. Therefore, when there is a possibility that there is a person in the living room L, it is preferable to change the wind direction downward and turn the air current from the bottom along the wall so that the air current flows without passing through the center of the living room L. If you don't know where a person is, turn the wind downwards to prevent the person from feeling a sense of airflow.

  As described above, according to the present embodiment, the ventilation control device 100 is a control target according to the indoor configuration, the arrangement of each equipment device 200 therein, and the detection result of the human sensor 300. The operation of the facility device 200 is set, and the control target facility device 200 is controlled according to the set operation. As a result, when the human sensor 300 detects the presence of a person, priority is given to the user's comfort, and when the presence of a person is not detected, ventilation can be performed with priority given to so-called energy saving. Become.

(Embodiment 3)
In the first embodiment, the example in which the exhaust auxiliary fan 263 is not included in the facility device 200 controlled by the ventilation control device 100 has been described. In the third embodiment, an example in which the facility device 200 includes the exhaust auxiliary fan 263 and the ventilation control device 100 further controls the exhaust auxiliary fan 263 will be described. In addition, about the structure which is the same as that of Embodiment 1, or equivalent, while using an equivalent code | symbol, the description is abbreviate | omitted or simplified. In the present embodiment, an open kitchen is assumed in which the far wall of the cooking device 220 as viewed from the cooker does not have a wall that partitions the room.

  As shown in FIG. 11, the ventilation system 3 according to the present embodiment includes a ventilation control device 100 that controls a plurality of facility devices 200. The facility device 200 includes a ventilation port 210, a cooking device 220, a range hood 230, a supply / exhaust fan 240, an air conditioning device 250, and an exhaust auxiliary fan 263. These are connected by a network N composed of a wired or wireless LAN except for the ventilation opening 210.

  The exhaust auxiliary fan 263 is a machine that applies pressure to the gas to give energy to the gas and increase the wind speed of the gas. The exhaust auxiliary fan 263 is used to assist the exhaust of the exhaust target generated by using the cooking device 220. Exhaust auxiliary fan 263 operates in accordance with control by ventilation control device 100, similarly to range hood 230 and supply / exhaust fan 240. Specifically, the air volume of the auxiliary exhaust fan 263 is controlled by the ventilation control device 100. Control of the exhaust auxiliary fan 263 by the ventilation control device 100 is realized by the ventilation control device 100 transmitting instruction data to the exhaust auxiliary fan 263. Therefore, the exhaust auxiliary fan 263 includes a communication unit (not shown). The exhaust auxiliary fan 263 includes, for example, a sirocco fan, a line flow fan, a turbo fan, an axial fan, and the like.

  Here, when the cooking device 220 is an IH cooking heater, the cooking device 220 includes a turbo fan for cooling the induction heating coil of the heating cabinet and a fan for cooling the power circuit board. It is common. Therefore, it is preferable to use these cooling fans as the exhaust auxiliary fan 263. For this reason, in this embodiment, the exhaust assist mechanism 260 is incorporated in the cooking device 220, and the cooling fan is used as the exhaust assist fan 263. According to such a configuration, it becomes possible to effectively utilize the configuration space of the IH cooking heater, and the IH cooking heater can be made compact.

  The exhaust assist mechanism 260 is a mechanism for guiding the exhaust target generated by using the cooking device 220 to the range hood 230. The exhaust assist mechanism 260 has a suction port 261 for sucking air in the external space into the exhaust assist ventilation passage, a discharge port 262 for exhausting air in the exhaust assist ventilation passage to the external space, and air in the external space. The exhaust auxiliary fan 263 that takes in the air from the suction port 261 into the exhaust auxiliary ventilation path and releases the taken air from the discharge port 262 toward the external space, and the air that is sucked from the suction port 261 and discharged to the discharge port 262 flows I A V-shaped exhaust auxiliary ventilation path (not shown). The exhaust assist mechanism 260 has a shape suitable for guiding the exhaust target, and is disposed at a position and orientation suitable for guiding the exhaust target. Note that “suitable for guiding the exhaust target” means that the exhaust target generated by cooking by the cooking device 220 can be effectively guided to the suction port of the range hood 230.

  It is desirable that the exhaust target generated by cooking be exhausted outside without being diffused indoors. For this reason, it is suitable for the ventilation control apparatus 100 to operate each equipment 200 so that the exhaust target generated by cooking is guided to the range hood 230 without being disturbed by various airflows generated in the room. . Usually, the exhaust target generated by cooking generates a rising airflow by obtaining the heat energy of the heat source of the cooking device 220. Most of the exhaust objects are collected by the operation of the range hood 230 and discharged outside the room, but some of the exhaust objects are diffused into the room without being collected. The collection amount and the diffusion amount do not depend only on the air volume of the range hood 230 or the positional relationship between the range hood 230 and the cooking device 220. That is, the collection amount and the diffusion amount depend on the operation state and arrangement relationship of each equipment device 200, the shape of the room, the weather, and the like. Therefore, in the present embodiment, a method will be described in which the ventilation control device 100 effectively guides the exhaust target to the suction port of the range hood 230 by controlling the range hood 230 and the exhaust auxiliary fan 263 in conjunction.

  There are mainly two methods for effectively guiding the exhaust target to the suction port of the range hood 230 using the exhaust assist mechanism 260. The first method is a method in which the exhaust assist mechanism 260 sucks the induction air from the suction port 261 and discharges it from the discharge port 262 toward the suction port of the range hood 230. According to the first method, the exhaust target immediately after being released into the room is guided to the suction port of the range hood 230 on the airflow created by the guidance air. In addition, the air for guidance may be air that is not an exhaust target, or may be an exhaust target that is circulated in the living room after being released into the room. The second method is a method in which the exhaust assist mechanism 260 directly sucks the exhaust target immediately after being released into the room from the suction port 261 and discharges it from the discharge port 262 toward the suction port of the range hood 230. . Hereinafter, an example in which the first method is adopted will be described with reference to FIGS. 12 to 14.

First, function information in the present embodiment will be described with reference to FIG. As shown in FIG. 12, the function information in the present embodiment is information obtained by adding the function information of the exhaust auxiliary fan 263 to the function information in the first embodiment. FIG. 12 shows that the air volume of the exhaust auxiliary fan 263 can be controlled in three stages: strong (1.7 m ³ ), medium (1.2 m ³ ), and weak (0.7 m ³ ). .

  Next, the control table in the present embodiment will be described with reference to FIG. As shown in FIG. 13, the control table in the present embodiment is a table that associates a ventilation index with control information including information related to the exhaust auxiliary fan 263. In FIG. 13, when the cooking device 220 is operated at “strong”, the range hood 230 is operated at “strong”, the supply / exhaust fan 240 is “stopped” (“stopped”), and the air conditioning device 250 is turned on. An example is shown in which the exhaust auxiliary fan 263 is operated with “weak” after operating “downward” with “weak”.

  FIG. 14 is a diagram schematically showing the flow of air due to indoor ventilation when the cooking device 220 is operated at “strong”. FIG. 14 shows a state in which an air flow is generated in the living room L by the cooperative operation of the range hood 230 and the air conditioner 250, and the exhaust auxiliary mechanism 260 takes in the air flow as guidance air and uses it for guidance of the exhaust target. Is shown. Hereinafter, the configuration and arrangement of the exhaust assist mechanism 260 will be described in detail.

  In FIG. 14, the suction port 261 is disposed on the wall surface on the living L side of the cooking device 220, opens toward the living L side, and the discharge port 262 is disposed on the upper surface of the cooking device 220. A state of opening toward the suction port 230 is shown. In this manner, the suction port 261 is installed at a position and an angle at which induction air (for example, air circulated through the living room L) can be effectively sucked. On the other hand, the discharge port 262 is installed at a position and an angle at which guidance air can be effectively supplied to the suction port of the range hood 230. Typically, the discharge port 262 is provided on the upper surface of the cooking device 220 at a position facing the suction port of the range hood 230. In other words, the discharge port 262 is disposed below (for example, directly below) the suction port of the range hood 230 and opens in a direction (for example, upward) where the suction port of the range hood 230 is located.

  The exhaust auxiliary fan 263 is disposed between the suction port 261 and the exhaust port 262 in the exhaust auxiliary ventilation path. The exhaust auxiliary fan 263 operates at “weak”, and generates a weak air flow from the suction port 261 toward the exhaust port 262 in the exhaust auxiliary ventilation path. According to such a configuration, the guiding air is taken into the exhaust auxiliary ventilation path from the suction port 261 and is discharged from the discharge port 262 toward the range hood 230. As a result, the exhaust target generated from the heat source is guided toward the range hood 230. Here, the discharge port 262 desirably has a smaller area than the suction port 261. According to such a configuration, the guiding air flowing toward the range hood 230 and the wind speed of the exhaust target are increased. As a result, the exhaust target generated from the heat source can be quickly guided to the range hood 230, and it is possible to further suppress the exhaust target from diffusing into the room.

  Although not explicitly shown in FIG. 13, the air conditioner 250 is preferably operated in the cooling operation rather than in the heating operation or the air blowing operation. That is, when the induction air is air cooled by the cooling operation of the air conditioner 250, the exhaust target generated from the heat source is guided and cooled toward the range hood 230 by the cooled induction air. . In general, the higher the temperature, the higher the diffusion rate of the substance, and the lower the temperature, the slower the diffusion rate. For this reason, the object to be exhausted generated from the heat source is cooled to reduce the diffusion speed, thereby suppressing the diffusion into the room. Note that the air conditioning apparatus 250 can guide the exhaust target with the air for guidance even when the air conditioning apparatus 250 operates not in the cooling operation but in the heating operation or the air blowing operation.

  In the present embodiment, the exhaust target generated from the heat source by the induction air is guided to the suction port of the range hood 230. For this reason, according to the position of the equipment 200 installed indoors, it becomes possible to ventilate the indoor air more efficiently. Moreover, in this Embodiment, the exhaust object containing oil smoke, an odor, etc. does not flow into an exhaust auxiliary ventilation path. Accordingly, it is possible to suppress the fixing of dirt and the generation of odor due to oil and odor adhering to the inside of the exhaust auxiliary ventilation path.

  In the present embodiment, the exhaust assist mechanism 260 is incorporated in the cooking device 220, and the cooling fan included in the cooking device 220 is used as the exhaust assist fan 263. For this reason, according to the present embodiment, it is possible to effectively utilize the limited kitchen space for the user, and in particular, to expand the selection range of products when there is a restriction on the size of the installed equipment due to renovation or the like. Can do.

(Embodiment 4)
In the second embodiment, the example in which the exhaust auxiliary fan 273 is not included in the equipment 200 controlled by the ventilation control device 100 has been described. In the fourth embodiment, an example in which the equipment device 200 includes the exhaust auxiliary fan 273 and the ventilation control device 100 further controls the exhaust auxiliary fan 273 will be described. In addition, about the structure which is the same as that of Embodiment 2, or equivalent, while using an equivalent code | symbol, the description is abbreviate | omitted or simplified. Further, the configuration of the ventilation system according to the present embodiment is the same as the configuration of the ventilation system 2 according to the second embodiment, except that an exhaust auxiliary fan 273 is provided as the equipment device 200.

  Embodiment 4 demonstrates the example which employ | adopts the 2nd method as a method of guide | inducing exhaust object to the suction inlet of the range hood 230. FIG. That is, in the present embodiment, a method will be described in which the exhaust assist mechanism 270 including the exhaust assist fan 273 sucks the exhaust target immediately after being released into the room from the suction port 271 and discharges it from the discharge port 272.

  Similar to the exhaust auxiliary fan 263, the exhaust auxiliary fan 273 is a machine that applies pressure to the gas to give energy to the gas and increase the wind speed of the gas. The exhaust auxiliary fan 273 is used to assist the exhaust of the exhaust target generated by using the cooking device 220. The exhaust auxiliary fan 273 operates in accordance with the control by the ventilation control device 100, similarly to the exhaust auxiliary fan 263. Specifically, the air volume of the auxiliary exhaust fan 273 is controlled by the ventilation control device 100. The control of the exhaust auxiliary fan 273 by the ventilation control device 100 is realized by the ventilation control device 100 transmitting instruction data to the exhaust auxiliary fan 273. Accordingly, the exhaust auxiliary fan 273 includes a communication unit (not shown). The exhaust auxiliary fan 273 includes, for example, a sirocco fan, a line flow fan, a turbo fan, an axial fan, and the like.

  Similarly to the exhaust assist mechanism 260, the exhaust assist mechanism 270 is a mechanism that guides an exhaust target generated by using the cooking device 220 to the suction port of the range hood 230. The exhaust assist mechanism 270 includes a suction port 271 for sucking air in the external space into the exhaust assist ventilation passage, a discharge port 272 for discharging the air in the exhaust assist ventilation passage to the external space, and the air in the external space. An exhaust auxiliary fan 273 that takes in the air from the intake port 271 into the exhaust auxiliary ventilation path and releases the air taken in from the exhaust port 272 toward the external space, and an exhaust gas through which the air sucked from the intake port 271 and discharged to the exhaust port 272 flows. An auxiliary ventilation path (not shown). The exhaust assist mechanism 270 has a shape suitable for guiding the exhaust target, and is disposed at a position and orientation suitable for guiding the exhaust target. In the present embodiment, exhaust assist mechanism 270 is not incorporated in cooking device 220 and is provided separately from cooking device 220. Therefore, the user can install the exhaust assist mechanism 270 in accordance with the housing situation.

  Hereinafter, the control table in the present embodiment will be described with reference to FIG. As shown in FIG. 15, the control table in the present embodiment associates the ventilation index including the state of the cooking device 220 and the detection result of the human sensor 300 with the control information including information regarding the exhaust auxiliary fan 273. It is a table. In FIG. 15, when the cooking device 220 is operated at “strong” and the human sensor 300 detects a person, the range hood 230 is operated at “strong” and the supply / exhaust fan 240 is “stopped” (“ In this example, the air conditioning device 250 is operated “down” and “weak”, and the exhaust auxiliary fan 273 is operated “medium”. In FIG. 15, when the cooking device 220 is operated at “medium” and the human sensor 300 detects a person, the range hood 230 is operated at “medium” and the supply / exhaust fan 240 is “stopped”. An example is shown in which the air conditioning device 250 is operated “down” and “weak”, and the exhaust auxiliary fan 273 is operated “medium”. When the exhaust auxiliary fan 273 is operated, it is possible to realize sufficient exhaust as an exhaust target without operating the air conditioner 250 as long as the range hood 230 is operating.

The function information in the present embodiment is, for example, the function information in the third embodiment shown in FIG. 12 in which the exhaust auxiliary fan 263 is replaced with the exhaust auxiliary fan 273, and thus the description thereof is omitted.

  FIG. 16 is a diagram schematically illustrating the flow of air due to indoor ventilation when the cooking device 220 is operated “strong” and a person is present on the living room L side. In FIG. 16, a state in which the air flow is generated in the living room L by the cooperative operation of the range hood 230 and the air conditioner 250, and the exhaust auxiliary mechanism 270 sucks the exhaust target and discharges it toward the suction port of the range hood 230. Show. Hereinafter, the configuration and arrangement of the exhaust assist mechanism 270 will be described in detail.

  In the present embodiment, the exhaust assist mechanism 270 employs a technique in which the exhaust target immediately after being released into the room is directly sucked from the suction port 271 and discharged from the discharge port 272. Therefore, as shown in FIG. 16, the suction port 271 is disposed on the wall surface facing the heat source of the exhaust assist mechanism 270, and the exhaust port 272 is disposed on the upper surface of the exhaust assist mechanism 270. More specifically, for example, the suction port 271 is installed at a position and an angle at which an exhaust target generated from a heat source can be effectively sucked. In other words, the suction port 271 is disposed in the vicinity of and above the heat source. More specifically, the suction port 271 is disposed on the wall surface on the heat source side of the exhaust assist mechanism 270 that protrudes from the upper surface of the cooking device 220 to the upper portion of the heat source of the cooking device 220. In addition, the suction port 271 opens in the direction in which the exhaust target is generated. Note that the suction port 271 is preferably provided with a member capable of adsorbing and removing oil and odor. Moreover, it is desirable that the width of the suction port 271 is wider than the width of the heat source. According to such a configuration, the area for collecting the exhaust target generated by cooking is increased, and it is possible to further suppress the exhaust target from diffusing into the room.

  On the other hand, the discharge port 272 is installed at a position and an angle at which the exhaust target can be effectively supplied to the suction port of the range hood 230. That is, the discharge port 272 is disposed on the upper portion of the exhaust assist mechanism 270. More specifically, the discharge port 272 is disposed at a position closer to the range hood 230 than the suction port 271 as viewed from the heat source, facing the suction port of the range hood 230. That is, the discharge port 272 is disposed below (for example, directly below) the suction port of the range hood 230 and opens in a direction (for example, above) where the range hood 230 has the suction port. The discharge port 272 desirably has a smaller area than the suction port 271. According to this configuration, since the guidance air flowing toward the range hood 230 and the wind speed of the exhaust target are increased, it is possible to further suppress the exhaust target from diffusing into the room.

  In addition, when the width of the suction port 271 is wider than the width of the heat source and the width of the discharge port 272 is not so wide, the thickness of the discharge port 272 is made narrower than the thickness of the suction port 271 to reduce the exhaust. The area of the outlet 272 can be made smaller than the area of the suction port 271. As described above, it is preferable that the size and shape of the suction port 271 and the discharge port 272 are adjusted so as to meet the design constraints.

  In the present embodiment, the exhaust target generated from the heat source is corrected so that the wind speed is increased by the exhaust assist mechanism 270 and the airflow direction is directed toward the suction port of the range hood 230. For this reason, according to this Embodiment, the spreading | diffusion to the room | chamber interior of exhaust object reduces, and efficient discharge | emission of exhaust object is implement | achieved.

In this case, for example, as shown in the example of FIG. 18, in the ventilation operation setting unit 134, the combination of the odor intensity of the kitchen K and the living L is set as the thermal power data, and the ventilation air volume of the range hood 230 is set as the control information. The air supply air volume of the air supply / exhaust fan 240 may be set.

(Modification 3)
The equipment 200 to be controlled is not limited to the range hood 230, the air supply / exhaust fan 240, and the air conditioner 250. It can be more or less than this.
For example, when the air conditioner 250 is not arranged and only the range hood 230 and the supply / exhaust fan 240 are installed, the control information may be as shown in FIG. 19, for example.
Moreover, the cooking device 220 is not limited to an IH heater. Other heat sources and cooking utensils such as gas stove and microwave oven may be used.

(Modification 4)
In the third embodiment, the example in which the I-shaped exhaust assist mechanism 260 is incorporated in the cooking device 220 has been described. In the present invention, various shapes of exhaust assist mechanisms can be incorporated into the cooking device 220. For example, as shown in FIG. 20A, a U-shaped exhaust assist mechanism 280 can be incorporated in the cooking device 220.

  Although the shape of the exhaust assist mechanism 280 is different from the shape of the exhaust assist mechanism 260, the function of the exhaust assist mechanism 280 is basically the same as the function of the exhaust assist mechanism 260. That is, the exhaust assist mechanism 280 is a mechanism that guides the exhaust gas such as smoke generated by using the cooking device 220 to the range hood 230. The exhaust assist mechanism 280 includes a suction port 281 for sucking air in the external space into the exhaust assist ventilation passage, a discharge port 282 for exhausting air in the exhaust assist ventilation passage to the external space, and air in the external space. An exhaust auxiliary fan 283 that takes in the air from the suction port 281 into the exhaust auxiliary ventilation path and releases the air taken in from the discharge port 282 toward the external space, and an exhaust gas through which the air sucked from the suction port 281 and discharged to the discharge port 282 flows. An auxiliary ventilation path (not shown).

  The suction port 281 is a hole for sucking the exhaust target generated from the heat source into the exhaust auxiliary ventilation path. The suction inlet 281 is arrange | positioned at the upper surface of the heating cooking appliance 220, and opens toward upper direction (namely, direction with the suction inlet of the range hood 230). The suction port 281 is disposed at a position closer to the heat source than the discharge port 282. The discharge port 282 is a hole for discharging the exhaust object sucked into the exhaust auxiliary ventilation path from the suction port 281 to the outside of the exhaust auxiliary ventilation path. The discharge port 282 is arrange | positioned at the upper surface of the heating cooking appliance 220, and opens upwards. The discharge port 282 is disposed at a position farther from the heat source than the suction port 281. The exhaust auxiliary fan 283 operates in accordance with control by the ventilation control device 100, similarly to the exhaust auxiliary fan 263.

  According to the fourth modification, the exhaust target generated from the heat source is sucked into the exhaust auxiliary ventilation path from the suction port 281 and discharged from the discharge port 282 toward the suction port of the range hood 230 after the wind speed is increased. The Therefore, according to the fourth modification, diffusion of the exhaust target into the room is reduced, and efficient exhaust of the exhaust target is realized.

(Modification 5)
In the fourth modification, an example has been described in which the suction port 281 is disposed closer to the heat source than the discharge port 282 when the U-shaped exhaust assist mechanism 280 is incorporated into the cooking device 220. In Modification 5, with reference to FIG. 20B, when the U-shaped exhaust assist mechanism 280 is incorporated into the cooking device 220, the suction port 281 is disposed at a position farther from the heat source than the discharge port 282. explain.

  The suction port 281 is a hole for sucking guidance air that guides the exhaust target to the suction port of the range hood 230 into the exhaust auxiliary ventilation path. The suction inlet 281 is arrange | positioned at the upper surface of the heating cooking appliance 220, and opens upwards. The suction port 281 is disposed at a position farther from the heat source than the discharge port 282. The discharge port 282 is a hole for discharging the guidance air sucked into the exhaust auxiliary ventilation path from the suction port 281 to the outside of the exhaust auxiliary ventilation path. The discharge port 282 is arrange | positioned at the upper surface of the heating cooking appliance 220, and opens upwards. The discharge port 282 is disposed at a position closer to the heat source than the suction port 281. The exhaust auxiliary fan 283 operates in accordance with control by the ventilation control device 100, similarly to the exhaust auxiliary fan 263.

  According to the fifth modification, the guidance air is sucked into the exhaust auxiliary ventilation path from the suction port 281, and is released from the discharge port 282 toward the suction port of the range hood 230 after the wind speed is increased. The exhaust target generated from the heat source is guided in the direction where the suction port of the range hood 230 is located by the guidance air flowing from the discharge port 282 toward the suction port of the range hood 230. Therefore, according to the modified example 5, the diffusion of the exhaust target into the room is reduced, and efficient exhaust of the exhaust target is realized. Moreover, in the modification 5, the exhaust object containing oil smoke, an odor, etc. does not flow into an exhaust auxiliary ventilation path. Therefore, according to the modified example 5, it is possible to suppress the fixing of dirt and the generation of odor due to oil and odor adhering to the inside of the exhaust auxiliary ventilation path.

(Modification 6)
In the fourth embodiment, the example in which the exhaust auxiliary fan 273 is disposed between the suction port 271 and the discharge port 272 in the exhaust auxiliary ventilation path has been described. In Modification 6, an example in which the exhaust auxiliary fan 293 is not disposed between the suction port 291 and the discharge port 272 in the exhaust auxiliary ventilation path will be described with reference to FIG.

  The exhaust assist mechanism 290 has a suction port 291 for sucking air in the external space into the exhaust assist ventilation passage, a discharge port 292 for exhausting air in the exhaust assist ventilation passage to the external space, and air in the external space. An exhaust auxiliary fan 293 that takes in the air from the suction port 291 into the exhaust auxiliary ventilation path and releases the air taken in from the discharge port 292 toward the external space, and an exhaust through which the air sucked from the suction port 291 and discharged to the discharge port 292 flows. An auxiliary ventilation path (not shown).

  The suction port 291 is a hole for sucking guidance air that guides the exhaust target to the suction port of the range hood 230 into the exhaust auxiliary ventilation path. The suction port 291 is disposed in the vicinity of and above the heat source. More specifically, the suction port 291 is disposed on the wall surface on the heat source side of the exhaust assist mechanism 290 that protrudes from the upper surface of the cooking device 220 to the upper part of the heat source of the cooking device 220. The suction port 291 opens in the direction in which the exhaust target is generated. The discharge port 292 is a hole for discharging the exhaust object sucked into the exhaust auxiliary ventilation path from the suction port 291 to the outside of the exhaust auxiliary ventilation path. The discharge port 292 is disposed on the upper portion of the exhaust assist mechanism 290. More specifically, the discharge port 292 is disposed at a position closer to the range hood 230 than the suction port 291 as viewed from the heat source, and opposed to the suction port of the range hood 230. That is, the discharge port 292 is disposed below the suction port of the range hood 230 and opens in a direction where the suction port of the range hood 230 is located.

  The exhaust auxiliary fan 293 operates in accordance with the control by the ventilation control device 100, similarly to the exhaust auxiliary fan 273. The exhaust auxiliary fan 293 is a cooling fan incorporated in the cooking device 220. The exhaust assist fan 293 is disposed below the exhaust assist mechanism 290 and generates an airflow that flows in a direction away from the heat source on the bottom surface of the exhaust assist mechanism 290. As a result, the exhaust target sucked into the exhaust auxiliary ventilation path from the intake port 291 proceeds downward in the exhaust auxiliary mechanism 290, proceeds in the direction away from the heat source in the vicinity of the bottom surface of the exhaust auxiliary mechanism 290, and then the exhaust auxiliary mechanism In 290, it proceeds upward and is discharged from the discharge port 282.

  According to the exhaust assist mechanism 290 according to the modified example 6, the exhaust target is sucked into the exhaust assist ventilation path from the suction port 291, the wind speed is increased, and then the exhaust port 292 is directed toward the suction port of the range hood 230. Released. Therefore, according to the exhaust assist mechanism 290 according to the modified example 6, diffusion of the exhaust target into the room is reduced, and efficient exhaust of the exhaust target is realized.

(Other variations)
The amount of electric power supplied to each facility device 200 may be measured, and so-called energy saving may be achieved by referring to the measurement result. Furthermore, by measuring the amount of power supplied for each equipment device 200, it is possible to determine whether each equipment device 200 is ON / OFF from the change in the power amount, and to perform the optimal operation according to the usage status of each equipment. Since it is possible to select, it is more effective for suppressing odor diffusion. Further, the power consumption of the cooking device 220 is directly associated with the heating state, and there is an advantage that the state of the cooking device 220 can be acquired without using a special sensor. Further, the ventilation control device 100 learns and stores the power consumption of each facility device 200 according to the time zone, so that the facility device 200 in use can be estimated.

  Although the range hood 230 is used for all of the above-described embodiments, this is a ventilation fan (ventilation fan for cooking) having an exhaust performance equivalent to that of the range hood 230 and a function of exhausting exhaust gas during cooking. You may substitute. This includes the above-described supply / exhaust fan 240 and the like. This is because an operation equivalent to that of the range hood 230 is performed when cooking in the living room L. However, in this case, since the installation position is different from that of the range hood 230, it is necessary to prepare a dedicated operation algorithm separately, and the user must select an optimal operation algorithm from the prepared operation algorithms.

As the equipment 200, for example, there are floor-mounted air blowers and air conditioners such as an air cleaner, a dehumidifier, a humidifier, and a fan, and the ventilation control device 100 grasps the operation of the equipment having all the air blowing functions. good. Alternatively, these installation positions may be input via the user interface 110, and the setting process may be provided with a step of judging the degree of influence and reselecting the operation algorithm. When the blower device or the air conditioner is present other than the facility device 200, the stirring of the wind by the device other than the facility device 200 becomes a disturbance, which may promote the diffusion of the exhaust gas into the living room L. Therefore, the ventilation control apparatus 100 needs to grasp these disturbances as much as possible.
By grasping the disturbance described above, the ventilation control device 100 can instruct the user to stop the operation of the floor-standing equipment described above via the user interface 110, and is incorporated as the equipment 200. If so, a stop instruction can be issued, the disturbance factor can be reduced, and the exhaust gas diffusion can be stably suppressed. In particular, the exhaust gas during cooking has a strong odor and may deteriorate the deodorizing performance of the air cleaner.Therefore, substances that cause odor adhere to the equipment, and the odor is emitted from the outlet when operating outside cooking. It is effective in avoiding causing the cause of the malfunction which discharge | releases.
Similarly, it may have a function of detecting or inputting an open window or door. This also has the effect of suppressing disturbance factors, like the floor-standing equipment described above.
On the other hand, if the above-described floor-standing device is incorporated in the operation algorithm as the facility device 200, it is possible to more efficiently suppress the diffusion of exhaust gas. For example, an air cleaner may have a deodorizing performance. If the exhaust gas can be sent along the wall or floor without going through the living room to the position of the suction port of the air cleaner, Can be suppressed. Moreover, by comprising in this way, it leads also to the effect which takes in waste gas into a floor-standing apparatus unnecessarily, and suppresses that an odor is re-released when a floor-standing apparatus is operated other than at the time of cooking.

  You may comprise so that an external terminal may be used for the communication part 16 and data may be input from an external terminal or a notification may be received.

  A smoke sensor may be installed in the range hood 230 so that data indicating the measured amount of smoke is transmitted to the ventilation control device 100 instead of the degree of heating power of the cooking device 220.

  In addition, a sensor that measures the temperature of the food being cooked by the cooking device 220 is installed in the range hood 230 or the like, and the degree of the measured temperature is transmitted to the ventilation control device 100 instead of the degree of the thermal power. May be.

In the network N, a PAN (Personal Area Network) may be used. Although FIG. 1 and FIG. 8 assume a configuration via a LAN, in recent years, the equipment 200 has an increased number of products that individually have sensors and the like that can be optimized and individually controlled. The above-mentioned implementation is performed without obtaining control information of the cooking device 220 and the range hood 230 by processing the data as a standard unified within the equipment device 200 and making it possible to perform two-way communication individually. The operation described in the form can be executed.
For example, when the human sensor 300 disclosed in the second embodiment detects that a person is in the kitchen K and predicts a cooking operation, the location where the human sensor 300 is introduced, for example, the air conditioner 250 or the like is mainly used. Operation may be performed. That is, if there are a device having a function of controlling the flow of air and a device having a means for determining the presence or absence of cooking in the facility device 200, the ventilation system 1 is not limited to the type and number of the facility devices 200. It becomes possible, and the versatility of the ventilation system 1 increases. Further, by adopting such a configuration, a part of information can be exchanged without going through the ventilation control device 100, so that an effect of speeding up the operation can be expected.

In the above-described embodiment, it has been described that the ventilation control device 100 sets the ventilation operation based on the arrangement information acquired from the user. However, the ventilation operation is manually performed by the user via the input unit 14. It may be set. In particular, the manner of feeling smoke and odor varies from person to person, and the positions of the mouth and nose are also different, so the assumed operation algorithm is not always the best. In addition, since error fluctuations due to seasons, temperature and humidity conditions, and the like may occur, it is possible to reduce discomfort felt by the user by making fine adjustments themselves. Further, the ventilation control device 100 can record the fine adjustment with the time schedule, record it, perform learning, and analyze it, so that the operation can be made more accurate.
In addition, the user may individually operate the equipment device 200 to set the operation without using the input unit 14. That is, it is desirable that the user can select the specifications so that the single control of the equipment 200 is not impaired by introducing the ventilation system 1. With this function, when the user wants to prioritize comfort and the like due to temperature and humidity over the diffusion of the exhaust gas into the living room L, the user can selectively select and secure versatility.

  In the third embodiment, the example in which the ventilation control device 100 controls the amount of air blown by the exhaust auxiliary fan 263 has been described. In the present invention, the ventilation control device 100 may further control the direction of the blown air (that is, the rotation direction of the fan) in addition to the amount of the wind blown by the exhaust auxiliary fan 263. Further, the ventilation control device 100 may control the direction of the wind that the exhaust auxiliary fan 263 blows out. In this case, the exhaust assist mechanism 260 may include a louver, and the ventilation control device 100 may transmit instruction data to the louver to control the direction of the blowing air.

  In Embodiment 4, when it is an open kitchen which has living L in front of the user who cooks (when there is no wall in the front of heating cooking appliance 220 seeing from the user who cooks), it is an exhaust assistance mechanism in the front of cooking appliance 220 The example in which 270 (exhaust exhaust ventilation path) is provided has been described. In this invention, when it is a semi-open kitchen which has living L on the side of the user who cooks (when it sees from the user who cooks, there is a wall in the front surface of the cooking device 220, and there is no wall in the side surface of the cooking device 220) The exhaust assist mechanism 270 (exhaust assist ventilation path) may be provided on the side surface of the cooking device 220. In this case, it is possible to suppress diffusion of high-temperature oily smoke or water vapor to equipment (for example, a sink or a microwave oven) on the side surface of the cooking device 220.

  Basically, the temperature and diffusion direction of the exhaust target vary depending on the heating method. Therefore, in the present invention, a device for detecting a heating method may be provided, and the amount and direction of air released from the exhaust auxiliary ventilation path may be adjusted according to the detected heating method. Devices that detect the heating method are, for example, a temperature sensor, an odor sensor, and a smoke sensor. Or the apparatus which detects the heating method may be an apparatus which receives designation | designated of the heating method by a user. Or the apparatus which receives the information which shows a heating method from the heat cooking apparatus 220 may be sufficient. Alternatively, the range hood 230 or other equipment 200 may have a function of detecting the heating method from the heating time or the temperature transition. Note that the amount of air released can be adjusted by controlling the rotational speed of the fan, and the direction of the released air can be adjusted by controlling the angle of the louver provided at the discharge port. . As a heating method, there are a method of heating with gas (a method of heating with a gas cooking device) and a method of heating with IH (a method of heating with an IH cooking heater).

  In the present invention, the ventilation control device 100 may include an operation receiving unit that receives an operation for designating the equipment device 200 to be operated, and a display unit that displays an operation status of each equipment device 200. The operation reception unit corresponds to, for example, the input unit 14, and the display unit corresponds to, for example, the output unit 15. According to this configuration, the user can select the facility device 200 to be operated by an operation on the operation reception unit while confirming the operation status of each facility device 200 displayed on the display unit. In addition, the user can determine the combination of the equipment 200 to operate in consideration of comfort and exhaust efficiency.

  Moreover, in this invention, the ventilation control apparatus 100 is provided with the memory | storage part which memorize | stores the information which shows the selection condition of the equipment 200, and the operation history of the equipment 200, and a display part displays the information memorize | stored in the memory | storage part. Also good. The storage unit corresponds to, for example, the auxiliary storage unit 13. According to such a configuration, the user can verify the combination of the equipment devices 200 that is optimal as the equipment device 200 to be operated in cooperation with reference to the information displayed on the display unit. For example, when the user selects the exhaust auxiliary fan 263 as the facility device 200 to be linked with the range hood 230 based on the information displayed on the display unit, the effect of suppressing the diffusion of the exhaust target generated from the heat source into the room is effective. Assume that it was the highest. In this case, the user operates the operation reception unit to select and operate the exhaust assist fan 263 as the equipment device 200 to be linked with the range hood 230. As a result, the facility device 200 having a relatively low effect of suppressing diffusion into the room to be exhausted can be excluded from the target of the cooperative operation. As a result, the operating equipment 200 can be reduced, so that energy consumption can be suppressed.

  In addition, the operation receiving unit, the display unit, and the storage unit described above are provided not in the ventilation control device 100 but in the equipment device 200 (for example, the cooking device 220, the range hood 230, the supply / exhaust fan 240, and the air conditioning device 250). Also good. In this case, information indicated by the operation received by the operation receiving unit, information displayed on the display unit, information stored in the storage unit, and the like are transmitted and received between the equipment device 200 and the ventilation control device 100. . According to this configuration, the user can operate the operation reception unit provided in the equipment device 200 with reference to the display unit provided in the equipment device 200. That is, according to such a configuration, information can be input / output using resources provided in the equipment device 200.
