FIG. 3 is a diagram showing an overall configuration of the ventilation system 100 according to Embodiment 1 of the present invention.
As shown in FIG. 3, the ventilation system 100 includes a plurality of exhaust means 12, system control means 14, and operation means 15.

  The system control unit 14 includes a number detection unit 14a, a heating operation detection unit 14b, and a storage unit (not shown), and is a control unit that controls the exhaust unit 12 based on various detection information. The system control unit 14 is configured by, for example, hardware such as a circuit device that realizes this function, or software executed on an arithmetic device such as a microcomputer or a CPU. The storage means is configured by an arbitrary storage medium such as an HDD (Hard Disk Drive) or a flash memory.

  The number detection means 14 a is a sensor that detects the number of the exhaust means 12 by detecting the current that flows during operation of the exhaust means 12. The heating operation detection unit 14 b is a sensor that detects information related to the operation status of the heating unit 13. Examples of the information to be detected include information indicating that the heating operation is being performed and information indicating that the heating operation has been stopped. The operation means 15 is for adjusting the temperature and humidity inside the residence 50, the total exhaust amount exhausted from all the exhaust means 12, etc., and is constituted by a remote controller that can be remotely operated, for example.

Below, control of ventilation system 100 is explained.
First, information on the heating means 13 and the operation means 15 is input to the system control means 14. Next, the system control unit 14 controls the exhaust unit 12 based on information of the heating unit 13, the number detection unit 14 a, the heating operation detection unit 14 b, and the operation unit 15. The system control means 14 stores the exhaust amount of the exhaust means 12 in the storage means.

  Next, the operation of the exhaust unit 12 is controlled by the system control unit 14, and for example, the house is constantly ventilated to ensure the total exhaust amount set by the operation unit 15. In addition, all the areas of the residence 50 are configured to be able to ventilate by supplying and exhausting air, respectively, and supply / exhaust to the residence 50 from other locations is substantially absent.

  FIG. 4 is a flowchart showing a control process of ventilation system 100 according to Embodiment 1 of the present invention. Hereinafter, the control content of the ventilation system 100 of the first embodiment will be described with reference to the flowchart of FIG.

  When the power supply of the ventilation system 100 is turned on, the system control means 14 operates the exhaust means 12 provided for each area (S1). Then, the number detecting means 14a detects the current flowing during the operation of the exhaust means 12 and calculates the number of exhaust means 12 (S2). Specifically, the number detection means 14a considers the case where a plurality of exhaust means 12 are installed in one area, determines the presence / absence of the exhaust means 12 using a preset current determination value as a threshold, and determines By summing up the results, the number of exhaust means 12 is calculated.

  When the number detection means 14a finishes calculating the number of exhaust means 12 installed for all areas (YES in S3), the process proceeds to S4. On the other hand, if the number detection means 14a has not finished calculating the number of installed exhaust means 12 for all areas (NO in S3), the process returns to S1.

  If YES in S3, the system control unit 14 causes the exhaust unit 12 to start ventilation (S4). When the heating operation detection unit 14b detects the operation of the heating unit 13 in the bathroom 4 during the regular ventilation (YES in S5), the process proceeds to S6. On the other hand, when the heating operation detection unit 14b does not detect the operation of the heating unit 13 in the bathroom 4 during the regular ventilation (NO in S5), the process returns to S4.

  In the case of YES in S5, the system control means 14 stops the operation of the exhaust means 12 in the bathroom 4 (S6). Next, the system control unit 14 calculates an increase in the exhaust amount per unit of the exhaust unit 12 whose operation is not stopped (S7). Then, the system control means 14 operates the exhaust means 12 other than the exhaust means 12 in the bathroom 4 by increasing the exhaust amount per one exhaust means 12 calculated in S7 (S8). Hereinafter, a method for calculating an increase in the exhaust amount per exhaust unit 12 will be described.

First, the system control unit 14 divides, for example, the total exhaust amount Q ₀ set by the operation unit 15 by the total number of exhaust units 12 to calculate the exhaust amount Q ₁ per exhaust unit 12. Here, in this Embodiment 1, the exhaust means 12 is each installed in four areas (LDK3, the bathroom 4, the washroom 5, and the toilet 6). Therefore, the exhaust amount Q ₁ per exhaust unit 12 is calculated by dividing the total exhaust amount Q ₀ by 4, which is the total number of exhaust units 12 installed. That is, Q ₁ = Q _0/4 units. At this time, the system control unit 14 stores the emissions to Q ₁ per exhaust means 12 to the storage unit.

Next, the system control unit 14, the exhaust amount to Q ₁ per exhaust means 12, divided by the number of exhaust means 12 is not stopped, the exhaust volume increment Q _{Stay up-per} single exhaust means 12 calculate. Here, in the first embodiment, when the heating operation detection unit 14b detects the operation of the heating unit 13 in the bathroom 4 during the constant ventilation (S5), the system control unit 14 performs the operation of the exhaust unit 12 in the bathroom 4. In order to stop (S6), only the exhaust means 12 installed in the three areas (LDK3, washroom 5, toilet 6) is operated. Therefore, the exhaust amount increment Q _{Stay up-per} single exhaust means 12, the exhaust amount to Q ₁ per exhaust means 12, dividing by 3 operation is the number of exhaust means 12 is not stopped Is calculated by That _is, the _Q up ₌ Q 1/3 units.

The value obtained by adding the exhaust amount increase Q _up per unit of the exhaust unit 12 to the exhaust amount Q ₁ per unit of the exhaust unit 12 is the value after the operation of the exhaust unit 12 of the bathroom 4 is stopped. , the exhaust amount Q _1up per one exhaust means 12 operation is not stopped. That is, Q _1up = Q ₁ + Q _up . For this reason, the ventilation system 100 according to the first embodiment can perform exhaust control in which the exhaust amount of the stopped exhaust unit 12 is distributed to the other exhaust units 12 while maintaining the total exhaust amount of the exhaust unit 12. it can.

  In the above description, the example in which the exhaust amount of the exhaust unit 12 whose operation is stopped is equally distributed to all the exhaust units 12 whose operation is not stopped has been described, but the present invention is not limited to this. For example, 40% of the exhaust amount of the exhaust means 12 of the bathroom 4 is distributed to the LDK 3, 30% of the exhaust amount of the exhaust means 12 of the bathroom 4 is distributed to the toilet 5, and the exhaust amount of the exhaust means 12 of the bathroom 4 is 30% may be distributed to the toilet 6. Further, for example, 50% of the exhaust amount of the exhaust means 12 of the bathroom 4 is distributed to the LDK 3, and 50% of the exhaust amount of the exhaust means 12 of the bathroom 4 is distributed to the washroom 5. You may comprise so that 12 exhaust amount may not be distributed to the toilet 6. FIG.

  After the process of S8, when the heating operation detection means 14b detects the stop of the operation of the heating means 13 for heating the bathroom 4 (YES in S9), the process proceeds to S10. On the other hand, when the heating operation detection unit 14b does not detect the stop of the operation of the heating unit 13 that heats the bathroom 4 (NO in S9), the process returns to S8.

If YES in S9, the system control means 14 operates the exhaust means 12 of the bathroom 4 (S10). Then, the system control means 14 controls the other exhaust means 12 (other than the specific area having the heating means 13) so as to always ventilate with the exhaust amount before the heating means 13 is operated (S11). That is, the system control unit 14 operates the exhaust unit 12 so that the exhaust amount of all the exhaust units 12 becomes the exhaust amount before starting the heating operation. Here, as described above, the system control unit 14 stores the emissions to Q ₁ per exhaust means 12 to the storage unit. For this reason, the system control means 14 reads the exhaust amount before the operation of the exhaust means 12 in the bathroom 4 is stopped from the storage means, and controls the exhaust amount of the exhaust means 12.

The system control unit 14 may not include a storage unit that stores the exhaust amount Q ₁ per exhaust unit 12. In this case, the system control unit 14 calculates the total engine / installed base that has been set, calculates the emissions to Q ₁ per exhaust means 12 again, always based on the calculated air volume The exhaust means 12 may be controlled to perform ventilation.

  As described above, in the ventilation system 100 according to Embodiment 1, when the system control unit 14 starts the operation of the heating unit 13 while the exhaust unit 12 provided in the heating area is operated, The exhaust unit 12 provided in the heating area is stopped, and the exhaust amount of the stopped exhaust unit 12 is distributed to the plurality of exhaust units 12 provided in the plurality of ventilation areas, so that the exhaust amount of the plurality of exhaust units 12 is distributed. Increase. For this reason, the enlargement of the exhaust means 12 can be suppressed. Since the exhaust means 12 can be prevented from increasing in size in this way, it is possible to reduce the feeling of cold wind, especially in winter, and it is difficult for the user to feel the chill of the area heated by the heating means 13. Moreover, since the enlargement of the exhaust means 12 can be suppressed, the noise accompanying the increase in the blowing sound of the exhaust means 12 can be reduced.

  Moreover, the ventilation system 100 is provided with the number detection means 14a. For this reason, when the number detection means 14a calculates the number of installed exhaust means 12, the exhaust amount of the exhaust means 12 whose operation has stopped can be distributed to the exhaust means 12 whose operation has not stopped.

  In addition, although the example which provided the heating means 13 in the bathroom 4 was demonstrated in the example mentioned above, it is not limited to this, You may provide the heating means 13 in another area.
