Will ventilate. Even if the design is such that the amount of exhaust for each cooker differs depending on the size of the flow path of the branch duct, the damper can only take either the open state or the closed state, and is set in advance. Only ventilation by exhaust distribution is possible. For this reason, there exists a possibility that excessive ventilation will be performed about the cooking area with few generation | occurrence | production degrees of cooking atmosphere. For this reason, excess energy may be consumed in ventilation control.

  This invention is made | formed in view of the point mentioned above, and when the subject of this invention ventilates several cooking areas in a kitchen, it saves energy, ensuring the ventilation amount corresponding to each cooking area. An object of the present invention is to provide a ventilation control system, a ventilation control method, and a ventilation control device that can be realized.

A ventilation control system according to a first aspect of the present invention is a ventilation control system for ventilating a kitchen provided with a plurality of cookers, and includes a first duct, a second duct, a first ventilation resistance adjusting unit, and a first ventilation resistance adjusting unit. 2 The ventilation resistance adjustment part, the ventilation duct, the ventilation fan, the acquisition part, and the control part are provided. A 1st duct makes object 1st area among the areas where the several cooker is arrange | positioned. A 2nd duct makes object 2nd area among the areas where the several cooker is arrange | positioned. The first ventilation resistance adjusting unit adjusts the first ventilation resistance in the first duct. The second ventilation resistance adjusting unit adjusts the second ventilation resistance in the second duct. The ventilation duct allows the first duct and the second duct to communicate with each other. The ventilation fan is provided in the ventilation duct and exhausts the air in the kitchen. The acquisition unit acquires cooking status information regarding the first area and cooking status information regarding the second area. The control unit controls the control of the first ventilation resistance adjusting unit, the control of the second ventilation resistance adjusting unit, and the control of the number of rotations of the ventilation fan in association with each other based on the information acquired by the acquiring unit. In addition, the control unit controls the lowering of the ventilation fan speed by controlling the related first ventilation resistance adjusting unit to lower the first ventilation resistance or controlling the related second ventilation resistance adjusting unit to lower the second ventilation resistance.

The control pattern when the representative cooker in the second area is ON is “control 2”, and the control pattern when the representative cooker in the first area is ON and the representative cooker in the second area is OFF is “control 3”. The control pattern when the representative cooker in the first area is ON and the representative cooker in the second area is ON will be described as “control 4”.

(Ventilation control flowchart)
In FIG. 4, the flowchart of the ventilation control in the ventilation control system of this embodiment is shown.

  In step S1, the control unit 34 of the controller 30 determines whether or not the operating status of the cooker 50 to be controlled has changed based on information obtained from the temperature sensor 40 at predetermined time intervals. If it is determined that the operating status has changed, the process proceeds to step S2, and if it is determined that the operating status has not changed, step S1 is repeated again with a predetermined time interval.

  In step S2, the control unit 34 of the controller 30 grasps the operating status of the cooking device 50 to be controlled, determines which of the control patterns stored in the control pattern storage unit 32 is used for control, and step S3. Migrate to

  In step S <b> 3, the control unit 34 of the controller 30 sends a frequency command to the supply fan motor 27 and the exhaust fan motor 23 via the communication unit 33, and the first damper adjustment unit 130 and the second damper adjustment unit 230. A damper opening command is sent to each to change the ventilation control state.

  In step S4, the change of the ventilation control state is terminated, the process proceeds to step S1 again, and this is repeated.

(Control pattern example 1)
In FIG. 5, “control 1” in the case where the maximum passage areas of the first damper 120 portion and the second damper 220 portion are equal and the maximum loads of cooking conditions in the first area and the second area are equal. -The example of the control pattern of "control 4" is shown. Here, the opening degree of the first damper 120 and the second damper 220 is set in two patterns, that is, a fully open state (“full” shown in FIG. 5) and a squeezed state (“small” shown in FIG. 5). Has been.

  In any of the following controls, one of the first damper 120 and the second damper 220 is maintained so as to be fully opened. Further, both the first damper 120 and the second damper 220 are kept so as not to completely close the respective ducts. Accordingly, since at least one of the dampers is fully opened, the pressure loss can be suppressed and the rotational speed of the exhaust fan 22 can be reduced, thereby saving energy. Furthermore, by avoiding a state where all the ducts are closed, it is possible to secure a situation in which ventilation in the kitchen is possible and improve safety.

  “Control 1” is a state in which the representative cookers 52 and 55 in each area are stopped, and the other cookers 51, 53, 54, and 56 other than the representative cooker are always operating. (See FIG. 3). Here, since the loads in the first area and the second area are the same, both the first damper 120 and the second damper 220 are adjusted so as to be fully opened, and the same base exhaust in each duct. The amount is controlled to ensure.

  “Control 2” is a control pattern in which the side dish gas table 55, which is a representative cooker in the second area, is operating, and the ventilation load is larger in the second area than in the first area. Here, the second area 220 is controlled to be preferentially ventilated by fully opening the opening degree of the second damper 220 and adjusting the opening degree of the first damper 120 to the throttle. In this way, by controlling the opening degree of the first damper 120 in a throttle manner, the total exhaust amount can be suppressed, the rotational speed of the exhaust fan 22 can be reduced, and the load applied to the exhaust fan motor 23 can be suppressed. To save energy.

  “Control 3” is a control pattern in which the lunch table gas table 52, which is a representative cooker of the first area, is operating, and the ventilation load is larger in the first area than in the second area. Here, the first damper 120 is controlled to be preferentially ventilated by fully opening the opening of the first damper 120 and adjusting the opening of the second damper 220 so as to be throttled. In this case as well, as in “Control 2”, energy saving is achieved by suppressing the load applied to the exhaust fan motor 23.

  In “control 4”, the lunch table gas table 52, which is a representative cooker in the first area, and the side dish gas table 55, which is a representative cooker in the second area, are in operation, and the first area, the second area, It is a control pattern in the state where the ventilation load of the same is large. Here, the opening degree of each damper 120, 220 is adjusted to be fully open. Thereby, the exhaust amount of both ducts having the same maximum passage area can be adjusted equally, and ventilation can be performed without being biased toward the first area or the second area.

(Control pattern example 2)
In FIG. 6, “control 1” in the case where the second damper 220 portion has a larger maximum passage area than the first damper 120 portion, and the second area has a larger maximum cooking load and base load than the first area. The example of a control pattern of "-" control 4 "is shown. Here, the opening degree of the first damper 120 is in a fully open state (“full” shown in FIG. 6), a throttled state (“small” shown in FIG. 6), and an intermediate opening state (“medium” shown in FIG. 6). )), And the opening degree of the second damper 220 has two patterns, a fully open state (“full” shown in FIG. 6) and a squeezed state (“small” shown in FIG. 6). Is set.

  “Control 1” is a state in which the representative cookers 52 and 55 in each area are stopped, and other cookers 51, 53, 54, and 56 other than the representative cooker are considered to be operating at all times. It is a control pattern. Here, since the base load is larger in the second area than in the first area, the first damper 120 is adjusted to an intermediate opening state, and the second damper 220 is adjusted to be in a fully open state to Control is performed so that ventilation in the large second area is given priority a little. In this case as well, energy saving is achieved by suppressing the load applied to the exhaust fan motor 23 as described above.

  “Control 2” is a control pattern in which the side dish gas table 55, which is a representative cooking device of the second area, is operating, and the ventilation load is considerably larger in the second area than in the first area. Here, the second area 220 is controlled to be preferentially ventilated by fully opening the opening of the second damper 220 and adjusting the opening of the first damper 120 to the throttle.

  “Control 3” is a control pattern in which the lunch table gas table 52, which is a representative cooker of the first area, is operating, and the ventilation load is larger in the first area than in the second area. Here, the first damper 120 is controlled to be preferentially ventilated by fully opening the opening of the first damper 120 and adjusting the opening of the second damper 220 so as to be throttled.

  In “control 4”, the lunch table gas table 52, which is a representative cooker in the first area, and the side dish gas table 55, which is a representative cooker in the second area, are in operation. This is a control pattern in a case where both the ventilation loads in the two areas are large and the load in the second area is slightly larger. Here, the opening degree of each damper 120, 220 is adjusted to be fully open. This minimizes the ventilation resistance in each duct and promotes ventilation.

<Characteristics of the ventilation control system of this embodiment>
(1)
In general, in a system that ventilates the kitchen, even if the degree of occurrence of cooking atmosphere such as oil smoke and mist differs among the plurality of cooking appliances that are subject to ventilation, each cooking appliance and cooking area Ventilate with equal strength. For this reason, when the necessary ventilation amount is secured for a certain cooking device / cooking area, the amount of ventilation in the vicinity of another cooking device / cooking area is also increased, and useless energy is consumed.

  On the other hand, in the ventilation control system in the above embodiment, the first passage area in the first duct 100 targeting the first area is adjusted by the first damper 120 and the first damper adjusting unit 130. Further, the second passage area in the second duct 200 targeting the second area is adjusted by the second damper 220 and the second damper adjusting unit 230. And the control part 34 can each control the opening degree of the 1st damper 120 and the 2nd damper 220 based on the cooking status information of each area. This makes it possible to distribute the ventilation amount with an emphasis on the area where ventilation is more required. Further, the control unit 34 links the opening control of the first damper 120 and the opening control of the second damper 220 with the control of the rotational speed of the exhaust fan 22. Thereby, it is possible to perform energy saving operation while suppressing the burden on the exhaust fan motor 23 while securing the necessary ventilation amount in each area.

(2)
In the ventilation control system in the above embodiment, the cooking devices 52 and 55 having the largest necessary ventilation amount in each area are set as representative cooking devices for control. Thereby, the control which paid its attention to the representative cooking appliance which has comparatively big influence in ventilation volume control is attained, and ventilation energy saving control according to the cooking condition of each area is enabled, simplifying control.

(3)
In the ventilation control system in the embodiment, the remote monitoring center 70 creates control pattern data for controlling the damper opening and the ventilation air volume based on information acquired by the sensor 40 and the like. Then, the control pattern data is transmitted to the control unit 34 of the controller 30 via the external terminal connection interface 31 to be reflected in the control executed by the control unit 34.

  This eliminates the need to dispatch a service engineer or the like to the site where the first duct 100, the second duct 200, the exhaust fan 22, and the exhaust fan motor 23 are installed, and from the installation location of the remote monitoring center 70, Remote operation can be performed. Further, when the remote monitoring center 70 collects a lot of data related to the control of the first duct 100, the second duct 200, the exhaust fan 22, and the exhaust fan motor 23, various control modes and control patterns in the control unit 34 are collected. The optimum control of set values can be managed remotely.

<Other embodiments>
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of invention.

(A)
In the ventilation control system of the above embodiment, referring to FIG. 6, in “control 4” of (control pattern example 2), the first damper 120 and the second damper 220 are both fully opened as an example. I explained. Thereby, the increase of the whole ventilation quantity is made easy by reducing the ventilation resistance in a duct.

  However, the present invention is not limited to this. For example, in view of the fact that the ventilation load is larger in the second area than in the first area, the control pattern “control 4” here is changed to the first damper 120. May be set to an intermediate opening state so that the second damper 220 is fully opened. In this case, it becomes possible to secure an exhaust amount corresponding to the ventilation load of the target area. Thereby, energy-saving control in which the rotational speed of the exhaust fan 22 is further reduced is possible. Moreover, since this can also reduce the operation load of the air conditioner etc. in a kitchen, energy saving can also be achieved from this point.

(B)
In the ventilation control system of the said embodiment, an example of the flow of ventilation control was demonstrated using the flowchart of FIG.

  However, the present invention is not limited to this, and ventilation control may be performed according to a flowchart shown in FIG. As described above, when it takes about 30 seconds to control the state of the opening of the first damper 120 or the second damper 220, the environment of the kitchen may change during the adjustment of the damper opening. is there. However, in this modification, even in such a case, as shown in FIG. 8, after the change operation is started in step S3 (A), in step S3 (B), the kitchen sensor again by the temperature sensor 40 or the like is used. By detecting the cooking status, it becomes possible to grasp whether the cooking status has changed during the adjustment of the damper opening. Thereby, when a cooking condition changes, it transfers to step S2 and ventilation control according to the changed cooking condition can be performed. That is, according to the control flow according to the present modification, ventilation control with improved real-time performance can be performed.

(C)
In the ventilation control system of the above embodiment, an example of the supply / exhaust amount and the opening control of the first duct 100 and the second duct 200 has been described using the sequence diagram of FIG.

  However, the present invention is not limited to this, and it is possible to perform sequence control as shown in FIG. 9, for example, taking into account that it takes time to control the opening of the damper. As described above, in the sequence control shown in FIG. 7, the control of the exhaust amount is completed before the damper opening is adjusted to the desired opening. In this case, during the control for reducing the exhaust amount (when the control pattern is changed from “Control 3” to “Control 1” in FIG. 7), in the temporary time until the adjustment of the damper opening is completed, The time zone which cannot secure the ventilation volume originally required will arise. That is, when the control pattern is changed from “Control 3” to “Control 1”, the exhaust amount (1820) required in the first duct 100 is temporarily insufficient, and the comfort of the kitchen cannot be maintained. There is.

  On the other hand, in the sequence control according to the modified example C, as shown in FIG. 9, when the control for reducing the ventilation amount is performed, the control state change of the exhaust amount is changed until the adjustment of the damper opening is completed. The interlocking control is delayed so as not to start. As a result, when control is performed to reduce the ventilation volume, it is possible to avoid that some areas of the kitchen are in a poorly ventilated state, and it is possible to maintain the kitchen environment in a comfortable state. .

(D)
In the ventilation control system of the above embodiment, the information obtained from the temperature sensors 41 and 42 disposed in the vicinity of the respective cookers 51 and 55 has been described as an example of the cooking status information.

  However, in the present invention, the information for grasping the cooking status information in the kitchen need not be limited to the temperature as described above. For example, a humidity sensor is provided to understand humidity information, the amount of gas used from a gas meter, etc., a sensor that detects a predetermined odor component sensor or oil smoke, a predetermined harmful component sensor, a floating dust sensor, etc. Ascertaining the cooking status in the kitchen by grasping the information of the kitchen, or by grasping the operating status of the cooking device directly from the ON / OFF switch provided in the cooking appliance, and performing ventilation control based on this Also good.

(E)
In the ventilation control system of the said embodiment, as shown in FIG. 6, the electromagnetic fryer 51 etc. were mentioned as an example and demonstrated as the cooking appliance 50 arrange | positioned in a kitchen.

  However, the cooker targeted by the present invention is not limited to these, and for example, griddles, grills, stoves, ovens, microwave ovens, boiled noodle devices, steamers, hot water baths, and electromagnetic cookers. It may be a dishwasher, a rice cooker, or the like.

  According to the present invention, when ventilation is performed for a plurality of cooking areas in a kitchen, it is possible to save energy while ensuring a ventilation amount corresponding to each cooking area, so that a plurality of exhaust ducts are provided, Application to a ventilation control system or the like that can adjust the flow rate of the exhaust duct is particularly useful.
