  The actual operating performance of the ventilator is not necessarily the specification value.For example, in the type of ventilator where the ventilator body is connected to the air supply duct and the exhaust duct, depending on the construction situation such as duct work at the time of construction Driving performance changes. Like the ventilator described in Patent Document 1, if the control content by the controller of the ventilator body is switched by the dip switch provided in the ventilator body, it is possible to perform function setting according to the construction situation at the time of installation. is there. However, when the user subsequently sets the function according to his / her preference, since the setting content by the dip switch is unknown to the user, it cannot be determined how much the specification value should be changed. It is difficult to set desired functions.

  In addition, the ventilator is not limited to the ventilators described in Patent Documents 1 and 2, and is mounted on the control board and stores functional information when the control board is replaced when a problem occurs in the ventilator body. The storage elements are also replaced together. For this reason, when the control board is replaced with a new one, the function setting content of the ventilator is set to the initial setting by the manufacturer, and when the control board is replaced with a new one, the function setting content of the ventilator is changed to another user. It becomes the setting contents by. Therefore, if the function setting performed by the user before replacing the control board is different from the initial setting by the manufacturer or the setting by another user, the user must reset the function after replacing the control board.

  The present invention has been made in view of the above circumstances, and is provided with a ventilation device body and a remote controller, and is easily ventilated when the control board or the remote controller of the ventilation device body is replaced. It is an object of the present invention to obtain a ventilation system that makes it easy to individually set the functions of a device and a plurality of ventilation device bodies.

  The ventilator of the present invention that achieves the above object is a ventilator comprising a ventilator main body that ventilates by driving a blower, and a remote controller that exchanges commands and information through communication with the ventilator main body. The apparatus main body includes a manual function setting unit for setting functions, a blower control unit that performs function setting according to the function setting command when the function setting command is transmitted from the remote controller, and controls the operation of the blower. A main body side data management unit that creates function setting data corresponding to the function setting command and updates function setting history data, and a main body side storage unit that stores function setting data and history data by the main body side data management unit The remote controller creates function setting data corresponding to the function setting command and updates function setting history data. The remote data storage unit stores the function setting data and history data stored by the remote data management unit, and when the history data is stored in the remote storage unit during startup processing, When function setting data is obtained from the unit and a function setting command is created, and history data is not stored in the remote storage unit and history data is stored in the main unit storage unit, the function setting data is received from the ventilator main unit. To create a function setting command, and when no history data is stored in either the remote-side storage unit or the main-unit storage unit, obtain information about the setting contents in the function setting unit from the ventilator main unit. And a command management unit that creates a setting command.

  In the ventilator of the present invention, since function setting data is stored in each of the main body side storage unit and the remote side storage unit, when the control board or the remote controller of the ventilator main unit is replaced, it is not replaced. Based on the function setting data stored in the storage unit, the function setting contents before replacement can be restored. In addition, when both the control board and the remote controller of the ventilator main body are replaced, the remote controller obtains information about the setting contents in the function setting unit provided in the ventilator main body and creates a function setting command. The user can display the content of the function setting command on the display unit of the remote controller and return the function setting to his / her preference. Since the function can be set based on the contents set in the function setting unit according to the construction status of the ventilator body, the user was more liking than the function setting based on the specification value Easy to return to function settings. Therefore, in the ventilator of the present invention, when the control board or the remote controller of the ventilator body is replaced, it is easy to return to the function setting content before the replacement.

Further, when sending the function setting command to the main body controller 30A from the remote controller 50A receives the predetermined signal from the transmission and reception control unit 44e _1, history data 45b according to the function set in the ventilator main body 40 (see FIG. 1) Is stored in the storage unit 45. The history data 45b is data indicating whether or not a function setting command is transmitted from the remote controller 50A to the main body controller 30A. As the history data 45b, for example, when the function setting command is not transmitted, “ When the function setting command is transmitted even once, the digital data “1” can be used, or the numerical value of the number of times the function setting command is transmitted can be used.

However, when the history data 45b is stored in the storage unit 45 at the time of the startup process described above, or in both the storage unit 45 and the storage unit 24 (see FIG. 2) of the main body controller 30A at the time of the startup process. historical data 45b, 24b for (history reference Figure 2 for data 24b) are function setting instruction command management section 44d ₁ if not stored is created, the creation and function setting data 45a corresponding to the function setting command Storage in the storage unit 45 can be omitted. Further, the storage of the history data 45b corresponding to the function setting command in the storage unit 45 can be omitted.

When the history data 45b is stored in the storage unit 45 during the startup process, the command management unit 44d ₁ obtains the function setting data 45a from the storage unit 45 and creates a function setting command. Further, when the history data 45b is not stored in the storage unit 45 and the history data 24b is stored in the storage unit 24 of the main body controller 30A during the start-up process, the ventilator main body 40, specifically, The function setting data 24a (see FIG. 2) is obtained from the main body controller 30A, and a function setting command is created. When the history data 45b and 24b are not stored in either the storage unit 45 or the storage unit 24 during the above startup process, the setting contents read by the data management unit 23c from the function setting unit 21 (see FIG. 2) Information is obtained from the ventilator main body 40, specifically the main body side controller 30A, and a function setting command is created. When the user inputs information related to function setting from the input unit 41, a function setting command is created based on the information.

When the command management unit 44d ₁ obtains the function setting data 24a from the main body side controller 30A, first, the transmission / reception control unit 44e ₁ is instructed to transmit the acquisition request for the history data 24b, and the history data 24b is returned. It is determined from the history data 24b whether there is a function setting change history. When it is determined that there is a function setting change history, the transmission / reception control unit 44e ₁ is instructed to transmit an acquisition request for the function setting data 24a. Similarly, when the command management unit 44d ₁ obtains the information from the data management unit 23c, the command management unit 44d ₁ instructs the transmission / reception control unit 44e ₁ to transmit the information acquisition request. When information related to a command other than the function setting command is input from the input unit 41, the command management unit 44d ₁ creates a predetermined command based on the information and transmits the command to the main controller 30A. the instructs the reception control unit 44e _1, when the detection result of the temperature sensor is obtained when the temperature sensor in the remote controller 50A is provided, the main body side the detection result reception control unit transmissions to the controller 30A 44e ₁ is instructed.

Send to 30A. Further, when the transmission and reception processing unit 43 a response to the request signal is received, it sends the response to the command management section 44d _1. When the command management unit 44d ₁ creates a function setting command, or when a temperature sensor is provided in the remote controller 50A, a detection result of the temperature sensor is obtained. The data is sent to the unit 43 and sent to the main body controller 30A.

  The storage unit 45 can be composed of a non-volatile storage element that can rewrite data, such as an EEPROM, and is electrically connected to the data management unit 44c described above to store the function setting data 45a and the history data 45b. Remember.

  When the main body side controller 30A and the remote controller 50A having the above-described configuration are provided in the ventilation device 60 (see FIG. 1), when the control board of the main body side controller 30A is replaced with a new or non-new one, the remote controller 50A Based on the function setting data 45a stored in the storage unit 45, a function setting command is created during the start-up process and is transmitted to the main body controller 30A. For this reason, the function setting content set by the user before the replacement of the control board is automatically returned.

  When the remote controller 50A is replaced with a new one, a function setting command is created during start-up processing based on the function setting data 24a (see FIG. 2) stored in the storage unit 24 of the main body controller 30A, and the main controller 30A. Therefore, the function setting content set by the user before the replacement of the remote controller 50A is automatically returned.

  Then, when the ventilation device 60 is newly installed, or when the control board of the main body controller 30A and the remote controller 50A are replaced with new ones at a time, based on the setting contents in the function setting unit 21 (see FIG. 2). Since the function setting command is created and transmitted to the main body controller 30A during the start-up process, the user displays the content of the function setting command after the start-up of the ventilation device 60 on the display unit 42 of the remote controller 50A (see FIG. 3). You can set the function according to your preference. Since the person in charge of the setting in the function setting unit 21 performs the function according to the construction status of the ventilator main body 40, the user can change the function according to his / her preference compared to the case where the function is set based on the specification value. It is easy to return to the function setting contents.

  Therefore, in the ventilator 60, even when one of the control board (the control board of the main body controller 30A) and the remote controller 50A of the ventilator main body 40 (see FIG. 1) and the remote controller 50A are replaced, the function setting contents before replacement are changed. Easy to return. When the control board of the main body side controller 30A is replaced, the user's trouble of performing the function setting again is reduced. Therefore, it is easy to take a coping method of replacing the control board when the ventilator main body 40 breaks down. It becomes easy to use members other than the control board in the ventilator main body 40 over a long period of time. For this reason, the time taken for disposal becomes longer, and the labor required for recovery for disposal is reduced.

  In the ventilation device 60 that exhibits the above-described technical effect, the content of the processing performed by the control unit 44A of the remote controller 50A can be selected as appropriate. Hereinafter, specific examples of the processing performed by the control unit 44A will be described with reference to FIGS. 4 and 5 while appropriately quoting the reference numerals used in FIGS.

  FIG. 4 is a flowchart schematically showing an example of processing performed by the control unit of the remote controller during start-up processing. In the illustrated example, the control unit 44A (see FIG. 3) of the remote controller 50A performs steps S1 to S7, steps S1, S2, S8 to S11, or steps S1 to S4, S12 to S14, and S11 during the startup process. Then, the function setting of the ventilator body 40 (see FIG. 1) is performed. In FIG. 4, the remote controller 50 </ b> A is abbreviated as “remote controller”, and the main body controller 30 </ b> A (see FIG. 2) is abbreviated as “main body”.

When the start-up process is started by energizing each of the ventilator main body 40 and the remote controller 50A, first, step S1 is performed. In step S1, the command management unit 44d ₁ of the control unit 44A accesses the storage unit 45 and reads the history data 45b (see FIG. 3). In the next step S2, the command management unit 44d ₁ determines whether or not there is a function setting change history on the remote controller 50A side based on the read history data 45b. When it is determined that there is a change history, the process proceeds to step S8 described later, and when it is determined that there is no change history, the process proceeds to step S3.

In step S3, the command management section 44d ₁ historical data 24b (see FIG. 2) of the main body controller 30A obtains. At this time, the command management unit 44d ₁ instructs the transmission / reception control unit 44e ₁ (see FIG. 3) to transmit the acquisition request for the history data 24b, and when the history data 24b is returned from the main body side controller 30A, the transmission / reception processing is performed. The history data 24b is received from the unit 43 (see FIG. 3). In the main body controller 30A that has received the acquisition request, the data management unit 23c reads the history data 24b from the storage unit 24 and sends it to the transmission / reception control unit 23d, and the transmission / reception processing unit 22 controls the transmission / reception control unit 23d. The history data 24b is transmitted to the remote controller 50A.

In the next step S4, the command management unit 44d ₁ determines whether or not the main body controller 30A has a function setting change history based on the acquired history data 24b. When it is determined that there is a change history, the process proceeds to step S12 described later, and when it is determined that there is no change history, the process proceeds to step S5.

In step S5, the remote controller 50A and to both historical data 45b of the main body controller 30A, since there is no 24b, information about the settings in the function setting unit 21 (see FIG. 2) instruction managing section 44d ₁ Ventilation Acquired from the apparatus main body 40. At this time, the command management unit 44d ₁ instructs the transmission / reception control unit 44e ₁ to transmit the acquisition request for the information, and when the information is returned from the main body controller 30A, the transmission / reception processing unit 43 returns the information. Receive. In the main body side controller 30A that has received the acquisition request, the setting reading unit 23b reads the setting content in the function setting unit 21 and sends it to the transmission / reception control unit 23d, and under the control of the transmission / reception control unit 23d, the transmission / reception processing unit 22 Transmits information on the setting contents to the remote controller 50A.

Next, at step S6 is performed, the command management section 44d ₁ creates a function setting command based on the acquired above information in step S5. At this time, in the illustrated example, the function setting data 45a is not created, stored in the storage unit 45, and the history data 45b is not updated by the data management unit 44c (see FIG. 3).

Thereafter, the process proceeds to step S7, transmits reception processing unit 43 to function setting command instruction managing section 44d ₁ created in step S6 under the control of the transmission and reception control unit 44e ₁ (see FIG. 3) to the main body controller 30A Then, the process of the control unit 44A at the start-up process ends.

  The above-described procedures of steps S1 to S7 are for the start-up process performed after newly installing the ventilation device 60 (see FIG. 1). In the main body controller 30A that has received the function setting command, the data management unit 23c creates the function setting data 24a corresponding to the function setting command and stores the function setting data 24a in the storage unit 24 and the history data 24b (see FIG. 3). ).

On the other hand, when the command management unit 44d ₁ determines that there is a function setting change history on the remote controller 50A side in step S2 described above and proceeds to step S8, the command management unit 44d ₁ stores the function setting data 45a from the storage unit 45. Is read. Then, at step S9 is performed, the command management section 44d ₁ creates a function setting command based on the function setting data 45a read out in step S8. At this time, in the illustrated example, the function setting data 45a is not created and stored in the storage unit 45 by the data management unit 44c.

In step S10, transmission and reception processing unit 43 is transmitted to the main body controller 30A function setting instruction command management section 44d ₁ created in step S9 under the control of the transmission and reception control unit 44e _1. Thereafter, the process proceeds to step S11, where the data management unit 44c updates the history data 45b, and the process of the control unit 44A during the start-up process ends.

  The processing in steps S1, S2, S8 to S11 described above is performed at the start-up process in the ventilator 60 for which the user has set the function, or the main body side in the ventilator 60 in which the user has set the function. This is a start-up process performed for the first time after replacing the control board of the controller 30A. In the main body controller 30A that has received the function setting command, the data management unit 23c creates function setting data 24a corresponding to the function setting command, stores the function setting data 24a in the storage unit 24, and updates the history data 24b.

Further, when proceeding to step S12 to determine the body-side command manager 44d ₁ and controller 30A has the function setting change history in step S4 described above, are stored in the storage unit 24 of the main body side controller 30A functions The command management unit 44d ₁ acquires the setting data 24a (see FIG. 2). At this time, the command management unit 44d ₁ instructs the transmission / reception control unit 44e ₁ to transmit the acquisition request for the function setting data 24a, and when the function setting data 24a is returned from the main body controller 30A, the transmission / reception processing unit 43 The function setting data 24a is received. In the main body controller 30A that has received the acquisition request, the data management unit 23c reads the function setting data 24a from the storage unit 24 and sends it to the transmission / reception control unit 23d, and the transmission / reception processing unit 22 is controlled by the transmission / reception control unit 23d. Transmits the function setting data 24a to the remote controller 50A.

Next, at step S13 is performed, the command management section 44d ₁ creates a function setting command based on the function setting data 24a acquired in step S12. At this time, the data management unit 44 c creates the function setting data 45 a and stores it in the storage unit 45. In step S14, transmission and reception processing unit 43 is transmitted to the main body controller 30A function setting instruction command management section 44d ₁ created in step S13 under the control of the transmission and reception control unit 44e _1. Thereafter, the process proceeds to step S11 described above, the data management unit 44c updates the history data 45b, and the process of the control unit 44A during the start-up process ends.

  The processes in steps S1 to S4, S12 to S14, and S11 described above are those at the start-up process that is performed for the first time after replacing the remote controller 50A in the ventilator 60 for which the user has set the function. In the main body controller 30A that has received the function setting command, the data management unit 23c creates function setting data 24a corresponding to the function setting command, stores the function setting data 24a in the storage unit 24, and updates the history data 24b.

  FIG. 5 is a flowchart schematically showing an example of processing performed by the control unit when the user sets a function from the remote controller after completion of the startup processing. In the illustrated example, the control unit 44A (see FIG. 3) of the remote controller 50A performs steps S21 to S24 to set the function of the ventilator main body 40 (see FIG. 1). In FIG. 4, the remote controller 50A is abbreviated as “remote controller”.

In step S21 performed first, it is determined whether or not a function setting change instruction has been input from the remote controller 50A, that is, whether or not the user has input information relating to function settings from the input unit 41 (see FIG. 3) of the remote controller 50A. or a command management unit 44d ₁ is determined. When it is determined that there is no input of the change instruction, the control of the control unit 44A related to the function setting is terminated, and when it is determined that the change instruction is input, the process proceeds to step S22.

In step S22, the command management unit 44d ₁ creates a function setting command corresponding to the change instruction. At this time, the data management unit 44 c creates the function setting data 45 a and stores it in the storage unit 45. Next, at step S23 is performed, transmission and reception processing unit 43 is transmitted to the main body controller 30A function setting instruction command management section 44d ₁ created in step S22 under the control of the transmission and reception control unit 44e _1. Thereafter, the process proceeds to step S24, where the data management unit 44c updates the history data 45b, and the process of the control unit 44A related to the function setting after the start-up process is completed is completed. In the main body controller 30A that has received the function setting command, the data management unit 23c creates function setting data 24a corresponding to the function setting command, stores the function setting data 24a in the storage unit 24, and updates the history data 24b.

Embodiment 2. FIG.
In the ventilator of the present invention, a data management unit that creates function setting data corresponding to a function setting command and updates function setting history data, and a memory that stores function setting data and history data by the data management unit Can be provided on at least one of the ventilator body and the remote controller. Therefore, the data management unit and the storage unit can be provided only in the main body side controller of the ventilator body, or can be provided only in the remote controller.

  FIG. 6 is a block diagram schematically showing an example of a main body side controller in the ventilation device of the present invention in which the storage unit and the data management unit are provided only in the remote controller. It is a block diagram which shows roughly an example of the remote controller in the said ventilation apparatus. The overall configuration of the ventilator including the main body side controller and the remote controller can be the same as the configuration of the ventilator 60 shown in FIG.

  The main body side controller 30B shown in FIG. 6 has the main body shown in FIG. 2 except that it includes a control unit 23B instead of the control unit 23A shown in FIG. 2 and does not include a storage unit. It has the same configuration as the side controller 30A. The configuration of the control unit 23B is the same as the configuration of the control unit 23A illustrated in FIG. 2 except that the control unit 23B does not include the data management unit 23c illustrated in FIG. Since the components shown in FIG. 6 have already been described with reference to FIG. 2, the same reference numerals as those used in FIG.

On the other hand, the remote controller 50B shown in FIG. 7 has the same configuration as the remote controller 50A shown in FIG. 3 except that it includes a control unit 44B instead of the control unit 44A shown in FIG. Yes. The configuration of the control unit 44B is the same as the configuration of the control unit 44A shown in FIG. 2 except that a command management unit 44d ₂ is provided instead of the command management unit 44d ₁ shown in FIG. Among the constituent elements shown in FIG. 7, constituent elements other than the command management unit 44d ₂ have already been described with reference to FIG. 3, and thus the same reference numerals as those used in FIG. 3 are used for these constituent elements. Reference numerals are assigned and explanations thereof are omitted.

Since the function setting history data is not stored in the main body side controller 30B (see FIG. 6), the command management section 44d ₂ immediately starts the main body side when the history data 45b is not stored in the storage section 45 during start-up processing. Information about the setting contents in the function setting unit 21 (see FIG. 6) is obtained from the controller 30B, and a function setting command is created based on the information. Except for this point, the command management unit 44d ₂ operates in the same manner as the command management unit 44d ₁ shown in FIG.

  In the ventilator provided with the main body side controller 30B shown in FIG. 6 and the remote controller 50B shown in FIG. 7, during the start-up process after replacing the control board of the main body side controller 30B with a new one or a non-new one. The function setting contents set by the user before the replacement are automatically returned. Further, when the ventilation device is newly installed, when the control board of the main body controller 30B and the remote controller 50B are replaced with new ones, or when only the remote controller 50B is replaced with new ones, the description will be given in the first embodiment. For the same reason as when the newly installed ventilator 60 (see FIG. 1) is newly installed, the user can easily return to the function setting content before replacement that suits his / her preference after the ventilator is started up.

  Therefore, in the ventilator, even when one of the control board on the ventilator main body side (the control board of the main body controller 30B) and the remote controller 50B is exchanged, it is easy to return to the function setting content before the exchange. Since the storage unit is not provided in the main body controller 30B, it is easy to reduce the manufacturing cost. Moreover, since it becomes easy to use members other than the control board in a ventilator main body for a long period for the same reason as in the ventilator 60 demonstrated in Embodiment 1, the period until disposal becomes long and is discarded. The time and effort required for the collection is reduced.

  Even in the ventilator having the above-described technical effect, the process performed by the control unit 44B of the remote controller 50B can be appropriately selected as in the ventilator 60 described in the first embodiment. Hereinafter, a specific example of processing performed by the control unit 44B will be described with reference to FIG. 8 with appropriate reference to the reference numerals used in FIG. 6 or FIG.

  FIG. 8 is a flowchart schematically illustrating an example of processing performed by the control unit of the remote controller during start-up processing in the ventilation device including the main body controller illustrated in FIG. 6 and the remote controller illustrated in FIG. . In the illustrated example, the control unit 44B (see FIG. 7) of the remote controller 50B performs steps S1, S2, S5 to S7, or steps S1, S2, S8 to S11 during the start-up process, and sets the function of the ventilator main body. To do. Since the processing contents in the individual steps are the same as the processing contents in the steps having the same reference numerals already described with reference to FIG. 4, the description thereof is omitted here.

  As is apparent from the comparison between FIG. 8 and FIG. 4, when it is determined in step S2 that the remote controller 50B has no function setting change history, the control unit 44B sequentially performs steps S5 to S7, and the main body side controller 30B. A function setting command is created based on the contents set by the function setting unit 21 (see FIG. 6), and the function setting command is transmitted to the controller 30B on the main body side to end the processing related to the function setting during the startup process. To do. When it is determined in step S2 that the remote controller 50B has a function setting change history, steps S8 to S11 are sequentially performed, and the function setting data 45a stored in the storage unit 45 of the remote controller 50B (see FIG. 7). The function setting command is generated based on the above, and the function setting command is transmitted to the main body controller 30B, and the processing related to the function setting at the start-up process is ended.

Embodiment 3 FIG.
FIG. 9 is a schematic view showing an example of the ventilation system of the present invention. The ventilation system 100 shown in the figure is constituted by three ventilation devices 60A, 60A, 60A included in the ventilation device of the present invention, and each ventilation device 60A is embedded in the ceiling of the room 110. 40A of ventilation apparatus main bodies and the remote controller 50C attached to the wall surface of the room 110 are included. However, there is only one remote controller 50C, and the remote controller 50C is connected to the main body side controller 30C of each ventilator main body 40A by a signal line 55. Each ventilator main body 40A has the same configuration as the ventilator main body 40 shown in FIG. 1 except that the main body side controller is the main body side controller 30C.

  FIG. 10 is a block diagram schematically showing an example of a main body side controller provided in each ventilator main body in the ventilation system shown in FIG. 9, and FIG. 11 shows each ventilator in the ventilation system shown in FIG. It is a block diagram which shows roughly an example of the remote controller connected to a main body.

As shown in FIG. 10, the main body side controller 30 </ b> C is provided with a control unit 23 </ b> C instead of the control unit 23 </ b> A shown in FIG. 2 and a representative machine designating unit 25, respectively. It has the same configuration as the main body controller 30A shown in FIG. The configuration of the control unit 23C is the same as the configuration of the control unit 23A illustrated in FIG. 2 except that the control unit 23C includes a blower control unit 23a ₂ instead of the blower control unit 23a ₁ illustrated in FIG. Of the components shown in FIG. 10, the remaining components excluding the blower control unit 23 a ₂ and the representative machine designating unit 25 have already been described with reference to FIG. 2. The same reference numerals as those used in FIG.

The blower control unit 23a ₂ is transmitted from the remote controller 50C (see FIG. 9) to the main body controller 30C when the ventilator main body 40A (see FIG. 9) is designated as the representative machine by the representative machine designating unit 25. Set the function according to the function setting command. On the other hand, when the ventilator main body 40A is not designated as the representative machine by the representative machine designation unit 25, the function setting from the remote controller 30C is performed if “valid” is selected in the valid / invalid selection unit of the remote controller 30C described later. The function is set according to the command, and if “invalid” is selected, the function is set according to the setting contents in the function setting unit 21 without following the function setting command. The representative machine designating unit 25 designates whether or not the ventilator main body 40A is to be the above-mentioned representative machine, and is constituted by, for example, a mechanical switch electrically connected to the control unit 23C.

On the other hand, the remote controller 50C shown in FIG. 11 is different from the control unit 44A shown in FIG. 3 except that it includes a control unit 44C and a valid / invalid selection unit 46, respectively. 3 has the same configuration as the remote controller 50A shown in FIG. The configuration of the control unit 44C is the same as the configuration of the control unit 44A shown in FIG. 3 except that a transmission / reception control unit 44e ₂ is provided instead of the transmission / reception control unit 44e ₁ shown in FIG. Among the components shown in FIG. 11, the remaining components excluding the transmission / reception control unit 44e ₂ and the valid / invalid selection unit 46 have already been described with reference to FIG. Are denoted by the same reference numerals as those used in FIG.

The transmission / reception control unit 44e ₂ has a function of transmitting a command signal corresponding to the selection result of the valid / invalid selection unit 46 in addition to the function of the transmission / reception control unit 44e ₁ shown in FIG. The valid / invalid selection unit 46 selects whether to validate or invalidate a function setting command transmitted from the remote controller 50C to the main body controller 30C (see FIG. 10). It consists of mechanical switches connected to each other.

When “valid” is selected by the valid / invalid selection unit 46, the transmission / reception control unit 44e ₂ transmits a command signal instructing to validate the function setting command from the remote controller 50C to the main body controller 30C. . When “invalid” is selected by the valid / invalid selection unit 46, a command signal instructing to invalidate the function setting command from the remote controller 50C is transmitted to the main body controller 30C.

  In the ventilator 60A (see FIG. 9) provided with the main body side controller 30C shown in FIG. 10 and the remote controller 50C shown in FIG. 11, the same control as that explained in the first embodiment is performed at the start-up process. The control unit 44C of the remote controller 50C performs a function setting command to the main body side controller 30C. At this time, the command signal corresponding to the selection result of the valid / invalid selection unit 46 is also transmitted to the main body controller 30C. The main body controller 30C that has received the function setting command and the command signal determines whether to follow the function setting command based on the designation content of the representative machine designation unit 25 and the command signal, and follows the function setting command. The function setting or the function setting according to the setting contents in the function setting unit 21 is performed to control the operations of the air supply fan and the exhaust fan.

  FIG. 12 is a flowchart schematically illustrating an example of processing performed when the main body controller determines the control content of the blower. In the illustrated example, the main body controller 30A (see FIG. 10) performs steps S31, S32, or steps S31, S33, S34, and determines the control content of the blower.

In step S31 performed first, the selection result of the valid / invalid selection unit 46 is “based on a command signal transmitted from the remote controller 50C (see FIG. 11) according to the selection result of the valid / invalid selection unit 46. The blower control unit 23a ₂ (see FIG. 10) determines whether or not it is “valid”. When it is determined to be “valid”, the process proceeds to step S32, in which function setting is performed according to the function setting command from the remote controller 50C, and the operation of each of the air supply fan and the exhaust fan is performed according to the function setting command. Decide what to control.

On the other hand, if it is determined in step S31 that it is not valid, that is, it is determined to be “invalid”, the flow proceeds to step S33, and the ventilator main body 40A (see FIG. 9) is represented by the representative machine designating unit 25 (see FIG. 10). The blower control unit 23a ₂ determines whether or not the air blower is designated. When it is determined that it is designated as the representative machine, the process proceeds to step S32 described above, and when it is determined that it is not designated as the representative machine, the process proceeds to step S34, and the setting contents in the function setting unit 21 (see FIG. 10). Then, it is determined that the operation of each of the air supply blower and the exhaust blower is controlled with the content corresponding to the content set in the function setting unit 21.

  In the ventilation system 100 including the three ventilation devices 60A for setting the functions in the ventilation device main body 40A as described above, at least one ventilation device 60A is designated as the representative machine. In the ventilation device 60A designated as the representative machine, as described above, the control unit 44C of the remote controller 50C performs the same control as that described in the first embodiment during the start-up process, and sends a function setting command to the main body side controller. Since the data is transmitted to 30C, the same technical effect as the technical effect described in the first embodiment is obtained.

  Further, a representative machine and a non-representative machine can be appropriately selected according to the installation position of each ventilation device main body 40A, and a command signal from the remote controller 50C is received by the valid / invalid selection unit 46 in the remote controller 50C. Since it is possible to select whether to enable or disable the non-representative machine, the function setting unit 21 (see FIG. 10) performs the desired function setting for each ventilator 60A. Can be done. Therefore, according to the ventilation system 100, it is easy to perform comfortable air conditioning according to the structure and layout of the room 110 (see FIG. 9).

  As mentioned above, although the ventilation apparatus and ventilation system of this invention were mentioned and mentioned about embodiment, as mentioned above, this invention is not limited to said form. The configuration of the ventilator excluding each of the main body controller and the remote controller can be appropriately changed according to the performance required for the ventilator. Further, the configurations of the main body side controller and the remote controller can be appropriately changed. For example, the setting reading unit 23b shown in FIG. 2 can be made independent of the control unit 23A and can be used together with the function setting unit 21 as a function setting management unit.

  Further, as described above, the data management unit and the storage unit in which the function setting data and the history data are stored can be provided only in the main body side controller of the ventilator main body. The configuration of the remote controller in this case may be a configuration in which the data management unit 44c and the storage unit 45 are omitted from the remote controllers 50A and 50B shown in FIG. 3 or FIG. In the remote controller configured in this manner, for example, the startup process is performed with the contents in which steps S1, S2, and S8 to S11 in the flowchart shown in FIG. Send to.

  The valid / invalid selection unit that selects whether the function setting command from the remote controller is valid or invalid can be configured using software in addition to the mechanical switch. In the case of configuration using software, for example, a predetermined input switch in the input unit of the remote controller is used as a switch for inputting a valid / invalid selection command, and valid / invalid is displayed on the display unit of the remote controller. A guide image for selecting invalid is displayed. The valid / invalid selection unit is provided in the remote controller in the third embodiment, but may be provided in the main body controller. When the valid / invalid selection part is provided in the main body side controller, it becomes possible to select whether the function setting command from the remote controller is valid or invalid for each ventilator main body. The present invention can be variously modified, modified and combined in addition to the above.
