Description

  The present invention relates to a ventilation system, and more particularly, to a ventilation system including a control unit that controls a ventilation unit so as to ventilate a room.

  2. Description of the Related Art Conventionally, a ventilation system including a control unit that controls a ventilation unit so as to ventilate a room based on an indoor air condition is known (for example, see Patent Document 1).

  The above-mentioned Patent Document 1 is based on a blower (ventilation means) that allows communication between indoors and outdoors, a dew condensation detection circuit (detection unit) that changes its conductive characteristics in response to humidity, and a detection signal from the dew condensation detection circuit. , A dew condensation determination unit that determines that the humidity environment is high humidity, and a switching unit and a drive circuit that start driving the blower when the humidity environment is determined to be high by the dew condensation determination unit. A ventilation fan is disclosed. As a result, when the humidity environment is high humidity, indoor air with high humidity is exhausted by the blower to the outside of the room, so that the indoor humidity becomes low and the occurrence of dew condensation in the room is suppressed.

Japanese Patent Laid-Open No. 10-122614

  Here, if the indoor temperature is sufficiently high, even if the humidity environment is high, the amount of moisture that can be held in the indoor air before the condensation will be sufficiently large, so condensation will occur. Hateful. However, in the ventilation fan described in Patent Document 1, since the drive of the blower is started when the humidity environment is high, the drive of the blower is started even when condensation is unlikely to occur. There seems to be an inconvenience. That is, in the ventilation fan described in Patent Document 1, although the occurrence of condensation can be suppressed, there is a problem that unnecessary ventilation means is driven.

  The present invention has been made to solve the above-described problems, and one object of the present invention is to suppress the drive of unnecessary ventilation means while suppressing the occurrence of condensation. To provide a ventilation system.

  The ventilation system according to one aspect of the present invention switches to the dew condensation determination mode when the detection unit for detecting the indoor air condition, the ventilation means for ventilating the indoor air, and the indoor air condition satisfy the first condition. And a control unit configured to start ventilation of the room when the indoor air condition satisfies a second condition different from the first condition during execution of the dew condensation determination mode. It is configured to control the ventilation means.

  In the ventilation system according to one aspect of the present invention, when the indoor air condition satisfies the first condition, the control unit is switched to the condensation determination mode, and the indoor air condition is the first while the condensation determination mode is being executed. When the second condition different from the condition is satisfied, the ventilation means is controlled to ventilate the room. Thereby, for example, the first condition can be set to a condition that can determine whether or not condensation can occur, and the second condition can be determined whether or not the possibility that condensation actually occurs is high. By setting the condition, it is determined whether or not the second condition is highly likely to actually occur in a state in which it is determined in advance that the condensation can occur to some extent in the first condition. . As a result, it is determined that there is a high possibility that condensation will occur in a state in which condensation is unlikely to occur, and the start of indoor ventilation can be suppressed. Therefore, unnecessary driving of the ventilation means can be suppressed while suppressing the occurrence of condensation.

  In the ventilation system according to the above aspect, the second condition is preferably configured by a condition that does not satisfy the first condition. With this configuration, for example, the first condition is set to a condition in which condensation is unlikely to occur at the present time but condensation is likely to occur if the situation changes. The condition can be set to a condition (a condition different from the first condition) in which it is possible to determine whether or not the situation has changed from the first condition and the possibility that condensation easily occurs is high. Thereby, the range which can discriminate | determine that it can suppress the drive of an unnecessary ventilation means can be narrowed, suppressing generation | occurrence | production of dew condensation by 1st condition and 2nd condition. As a result, unnecessary drive of the ventilation means can be suppressed more reliably while suppressing the occurrence of condensation.

  In the ventilation system according to the above aspect, the first condition and the second condition preferably include at least one of an absolute humidity condition related to absolute humidity and a relative humidity condition related to relative humidity. With this configuration, it is possible to suppress the occurrence of condensation while suppressing the occurrence of condensation based on at least one of the absolute humidity condition and the relative humidity condition in which it is easy to determine whether or not condensation can occur and the actual possibility of condensation. The ventilation means can be easily driven so as to suppress the drive of the necessary ventilation means.

  In this case, preferably, the first condition includes an absolute humidity condition, and the second condition includes a relative humidity condition. With this configuration, for example, by setting the absolute humidity condition of the first condition that the absolute humidity as the indoor air condition is equal to or lower than the predetermined absolute humidity, the indoor air condition is changed to a low temperature condition (in the air). The first condition can be set so that the first condition can be easily satisfied when the amount of water that can be held (saturated water vapor amount) is small. As a result, the first condition can be set to a condition that can determine whether or not condensation can occur. Further, in a state where the condensation determination mode is being executed and the room is at a low temperature, for example, by setting the relative humidity condition as the indoor air state to be equal to or higher than a predetermined relative humidity, the second condition is a relative humidity condition. The second condition is such that the second condition can be easily satisfied when the indoor air condition is such that there is no room for the amount of moisture that can be retained in the air and moisture that cannot be retained in the air is likely to condense. Can be set. As a result, the second condition can be made a condition that can determine whether or not there is a high possibility that condensation will actually occur. As described above, since the first condition includes the absolute humidity condition and the second condition includes the relative humidity condition, it is possible to easily suppress the generation of condensation and suppress unnecessary driving of the ventilation means. .

  In the configuration in which the second condition includes a relative humidity condition, preferably, the second condition includes a relative humidity condition and an absolute humidity condition. With this configuration, the second condition includes not only the relative humidity condition but also the absolute humidity condition related to the absolute humidity as well as the first condition, so that the first condition and the second condition are based on the absolute humidity. Can be associated. Thereby, since the first condition and the second condition can be clearly set based on the absolute humidity, the occurrence of condensation can be more reliably and easily suppressed based on the first condition and the second condition. While driving unnecessary ventilation means can be suppressed.

  In the ventilation system according to the aforementioned aspect, preferably, the second condition includes a plurality of different conditions, and the control means is any one of the plurality of different conditions in which the indoor air condition is during execution of the dew condensation determination mode. When the condition is satisfied, the ventilation means is controlled to start ventilation in the room. Here, not only when the indoor air condition is very likely to cause condensation, but also when the indoor air condition where the possibility of condensation is somewhat high continues. Is considered to occur easily. That is, a plurality of conditions may exist as conditions that are highly likely to cause condensation. Therefore, in the present invention, by setting the second condition so as to include a plurality of conditions in which condensation may actually occur, the occurrence of condensation can be suppressed more reliably.

  In the ventilation system according to the above aspect, the control means is preferably configured to continue to execute the dew condensation determination mode for a first period after the indoor air condition finally satisfies the first condition. That is, when the indoor air condition newly satisfies the first condition during the execution of the condensation determination mode, the execution of the condensation determination mode is extended from that point in the first period. With this configuration, for example, by satisfying the first condition, it is determined that the environment in which condensation is likely to occur in the room, such as in winter, and the condensation determination mode is executed. Even if the first condition is not satisfied, it can be determined that it is the winter time if the first condition is satisfied again within the first period. As a result, the condensation determination mode can be continuously executed over a long period of time in an environment where condensation is likely to occur in the room such as in winter.

  In the ventilation system according to the above aspect, preferably, the control means, after the end of indoor ventilation, when the indoor air condition satisfies a third condition different from the first condition and the second condition, the second period, The dew condensation determination mode is not executed. With this configuration, for example, by setting the third condition so that it is possible to determine that sufficient ventilation has not been achieved by indoor ventilation by the ventilation means, It can suppress that a ventilation means continues being driven.

  The ventilation system according to the above aspect preferably further includes heating means disposed in the room and having a heat source, and the control means controls the ventilation means based on the driving state of the heating means during execution of the dew condensation determination mode. It is configured to have priority over the control of the ventilation means. According to this configuration, when the heating unit is driven, the ventilation unit is driven to release the heat of the heating unit from the room to the outside regardless of the control of the ventilation unit during the execution of the dew condensation determination mode. New air can be taken into the room from the outside. Thereby, the heating in a heating means can be performed safely.

  In the ventilation system according to the above aspect, the detector preferably includes a detector and a control unit, and further includes a detector provided separately from the ventilator, and the detector control unit is configured to execute the dew condensation determination mode. When the indoor air condition satisfies the second condition, the ventilation means is controlled to start ventilation in the room by communicating from the detector to the ventilation means. If comprised in this way, unlike the case where a detection part and a control means are arrange | positioned in one apparatus which has a ventilation means, since a detection part can be separately arrange | positioned in the position away from the ventilation means, indoors A detection part can be arrange | positioned in the position which can judge an air state appropriately. Further, by providing the detector and the control means together in the detector, the indoor air condition detected by the detector can be transmitted to the control means without communication to the outside.

  According to the present invention, as described above, unnecessary driving of the ventilation means can be suppressed while suppressing the occurrence of condensation.

(Detailed control contents of control means of detection equipment)
Next, the detailed control content of the control means 27 of the detector 2 will be described.

  The control means 27 of the detector 2 is configured to control the ventilation device 4 so that the room 500 is ventilated when there is a risk of condensation in the room 500. Specifically, the control unit 27 controls the ventilation device 4 so that the room 500 is ventilated when the humidity (air condition) of the room 500 satisfies the ventilation determination condition during execution of the dew condensation determination mode. It is configured as follows. More specific description will be given below.

(Condensation judgment mode)
The control means 27 is configured to switch to the condensation determination mode and continue to execute the condensation determination mode for 24 hours when the humidity (air condition) of the room 500 satisfies the condensation determination condition. This condensation determination condition is a condition in which condensation is unlikely to occur at the present time, but condensation can occur depending on a change in the situation. The dew condensation determination condition is a condition that is easily satisfied, for example, in the Japanese winter season when humidity tends to be low. Here, by setting the dew condensation determination condition to an absolute humidity condition with a relatively small amount of moisture in the air, it is easy when the amount of moisture in the air increases (absolute humidity increases) or the temperature decreases. The water content can easily reach the saturated water vapor content. In other words, the condensation judgment condition is a condition that can easily cause condensation if the situation changes.There is a relatively large temperature difference between indoors and outdoors as in the above-mentioned winter in Japan, and the amount of moisture in the air due to humidification etc. This is a condition in which condensation can occur in a situation that is likely to change. Specifically, the dew condensation determination condition is a first absolute humidity condition in which the absolute humidity in the room 500 is 7 g / m ³ or less.

  The absolute humidity is stored in the storage means 28 and the relationship between the temperature and the relative humidity (% RH (relative humidity)), which is stored in the storage unit 28, the detection result of the temperature in the temperature sensor 215, the detection result of the relative humidity in the humidity sensor 216. Based on the absolute humidity acquisition map shown, it is acquired by the control means 27 every predetermined time. The dew condensation determination condition and 24 hours are examples of the “first condition” and the “first period” in the claims, respectively.

Further, when the humidity (air condition) of the room 500 satisfies the dew condensation determination condition (absolute humidity is 7 g / m ³ or less) again during execution of the dew condensation determination mode, the control means 27 starts from the time when it is satisfied again. The dew condensation determination mode is continuously executed for 24 hours. As a result, the control means 27 is configured to continue to execute the condensation determination mode for 24 hours after the humidity (air condition) of the room 500 finally satisfies the condensation determination condition.

(Ventilation judgment)
Here, in the present embodiment, the control means 27, when executing the dew condensation determination mode, when the humidity (air condition) of the room 500 satisfies either the first ventilation determination condition or the second ventilation determination condition. In addition, the ventilation device 4 is configured to start ventilation of the room 500. The first ventilation determination condition and the second ventilation determination condition are conditions that are highly likely to cause condensation, and are conditions that are easily satisfied when the room 500 is humidified. Specifically, the first ventilation determination condition includes both the second absolute humidity condition that the absolute humidity of the room 500 is greater than 7 g / m ³ and the first relative humidity condition that the relative humidity is 70% RH or more. Both of these conditions are met. The second ventilation determination condition includes a second absolute humidity condition that the absolute humidity as the air state of the room 500 is greater than 7 g / m ³ and a state where the relative humidity is 65% RH or more and continues for 5 minutes. This is a condition that satisfies both of the two relative humidity conditions. The first ventilation determination condition and the second ventilation determination condition are both examples of the “second condition” in the claims.

  Further, the first ventilation determination condition and the second ventilation determination condition have a first relative humidity condition and a second relative humidity condition related to relative humidity, respectively. Further, in the first ventilation determination condition and the second ventilation determination condition, the second absolute humidity condition regarding the absolute humidity is the same, but the conditions regarding the relative humidity (the first relative humidity condition and the second relative humidity condition) are different. Yes. Note that the first relative humidity condition that the relative humidity is 70% RH or more is different from the second relative humidity condition, and the relative humidity need not be continuously 70% RH or more. That is, if the relative humidity is 70% RH or more and the humidity in the room 500 is satisfied, it is determined that the first relative humidity condition is satisfied.

Further, “absolute humidity is 7 g / m ³ or less” which is the first absolute humidity condition of the dew condensation determination condition, and “absolute humidity is 7 g / m 2 which is the second absolute humidity condition of the first ventilation determination condition and the second ventilation determination condition. “It is larger than m ³ ” is a contradictory condition. That is, the second absolute humidity condition does not satisfy the first absolute humidity condition. As a result, both the first ventilation determination condition and the second ventilation determination condition are configured by conditions that do not satisfy the condensation determination condition. Further, both the first ventilation determination condition and the second ventilation determination condition are cases where the situation changes from the dew condensation determination condition and the possibility that condensation easily occurs is high.

  In addition, when controlling the ventilation device 4, the control unit 27 starts driving the fan unit 41 of the ventilation device 4 by wireless communication via the communication units 24 and 42 and continues driving for one hour. Transmit the signal as you would Thereby, the control means 46 of the ventilation device 4 starts driving the fan unit 41 based on an instruction from the control means 27 and continuously drives the fan unit 41 for one hour. At this time, the fan unit 41 is driven with a “weak” air flow for one hour. The air volume of the fan unit 41 may be an air volume other than “weak” (that is, “medium” or “strong”).

  As a result, the high-humidity air in the room 500 is discharged to the outside, and the low-humidity air outside the room is introduced into the room 500, so that the occurrence of condensation on the windows in the room 500 is suppressed. At this time, ventilation to suppress condensation is performed only in the winter season, etc., which satisfies the condensation judgment conditions. It is suppressed from being performed.

(Condensation judgment stopped)
Further, the control means 27 is configured to end the drive of the ventilation device 4 and end the condensation determination mode after the ventilation device 4 is continuously driven for one hour during the execution of the condensation determination mode. Has been. Then, the control means 27 does not execute the dew condensation determination mode for 3 hours after the end of driving the ventilation device 4 when the dew condensation determination stop condition is satisfied after the drive of the ventilation device 4 is finished (after the dew condensation determination mode is finished). It is configured to be in a state (condensation determination stop state). Here, even after the driving of the ventilation device 4 is finished, if the dew condensation determination mode is executed when the humidity (moisture amount) of the room 500 is not sufficiently lowered, the ventilation device 4 may be driven immediately. There is. That is, there is a possibility that the ventilation device 4 is continuously driven. Accordingly, in order to suppress the ventilation device 4 from being continuously driven, the dew condensation determination stop condition is set to a condition where the ventilation device 4 is likely to be continuously driven. Specifically, the dew condensation determination stop condition is a condition that the relative humidity is 63% RH or more. The dew condensation determination stop condition is an example of the “third condition” in the claims.

  On the other hand, when the dew condensation determination stop condition is not satisfied after the drive of the ventilator 4 (after the dew condensation determination mode ends), the humidity (moisture content) of the room 500 can be sufficiently lowered by driving the ventilator 4. Therefore, the control unit 27 is configured to determine whether or not to switch to the dew condensation determination mode as usual.

(Hotness judgment)
Moreover, the control means 27 is comprised so that heat-burn determination may be performed separately from the dew condensation determination mode. That is, the control means 27 is configured to control the ventilation device 4 so as to start the ventilation of the room 500 by switching to the heat-burning mode when the humidity (air condition) of the room 500 satisfies the heat-burning determination condition. Has been. This heat-burning determination condition is a condition that is highly likely to cause heat stroke in the room 500. Specifically, the heat burn determination condition is a condition that the WBGT in the room 500 is 29 ° C. or higher. That is, the heat-burning determination condition is a condition that is satisfied when the room 500 is mainly in a high temperature and high humidity state.

  Thereby, when there is a high possibility of heat stroke, the control means 27 controls the ventilation device 4. Specifically, the control means 27 transmits a signal that starts driving the fan unit 41 of the ventilation device 4 by wireless communication via the communication units 24 and 42. Thereby, the control means 46 of the ventilation device 4 starts driving the fan unit 41 based on the instruction of the control means 27. At this time, the fan unit 41 is driven with a medium air volume. The air volume of the fan unit 41 may be an air volume other than “medium” (that is, “weak” or “strong”).

  As a result, the high-temperature and high-humidity air in the room 500 is discharged outside, and the low-temperature and low-humidity air outside the room 500 is introduced into the room 500, so that the possibility of developing heat stroke in the room 500 is reduced.

(Heat-burning mode stop judgment)
In addition, when the ventilation device 4 is being driven in the heat-burning mode, the control unit 27 cancels the heat-burning mode when the humidity (air state) of the room 500 satisfies the heat-burning mode release condition, The ventilation device 4 is configured to control the ventilation of 500. The condition for canceling the heat-burning mode is a condition for determining that the possibility of developing heat stroke in the room 500 is low. Specifically, the heating mode release condition is a condition that the WBGT in the room 500 is less than 28 ° C. Thereby, it is possible to prevent the ventilator 4 from being driven unnecessarily in a state where the possibility of developing heat stroke is low.

  In addition, when the ventilation mode 4 is not canceled in the state where the ventilation device 4 is being driven in the heat-burning mode, the control means 27 is configured to continuously drive the ventilation device 4 for one hour. Is configured to control. And the control means 27 is comprised so that the drive of the ventilation apparatus 4 may be complete | finished and the heat-burning mode may be complete | finished, when the drive of the ventilation apparatus 4 is performed continuously for 1 hour.

  After that, after the drive of the ventilation device 4 is finished (after the end of the heat-burning mode), the control means 27 is 3 hours after the end of the drive of the ventilation device 4 when the WBGT in the room 500 does not satisfy the heat-burning mode release condition. It is configured not to execute the heat-burning mode. Here, even after the driving of the ventilation device 4 is finished, if the room 500 is in a high temperature and high humidity state, there is a possibility that the heat-burning mode is immediately executed and the ventilation device 4 is driven. That is, there is a possibility that the ventilation device 4 is continuously driven. Therefore, in order to prevent the ventilation device 4 from being continuously driven, when the heat-burning mode release condition is not satisfied, the heat-burning mode is suppressed from being executed for a predetermined period (3 hours). .

  On the other hand, if the WBGT in the room 500 satisfies the heating mode release condition after the driving of the ventilation device 4 (after the heating mode ends), the control unit 27 determines whether to switch to the heating mode as usual. It is configured to make such a determination.

  Further, as described above, the driving of the ventilation device 4 based on the heat-burning mode is performed when not only the room 500 but also the outside is hot. On the other hand, the driving of the ventilation device 4 during the execution of the dew condensation determination mode is performed when the room 500 can be at a low temperature (even when the room 500 is at a certain high temperature and the outside is at a low temperature). That is, the possibility that the driving of the ventilation device 4 based on the heat-burning mode overlaps with the driving of the ventilation device 4 during the execution of the dew condensation determination mode is sufficiently low.

(Control of ventilation equipment when cooking device is driven)
Further, when the control unit 27 is notified of the driving of the heating unit 31 (driving state of the cooking device 3) from the control unit 36 of the cooking device 3 via the communication units 24 and 32, the dew condensation determination mode and the heat-burning mode are performed. The ventilator 4 is configured to control the air volume according to the driving state of the cooking device 3 based on the driving state of the cooking device 3 in preference to the control of the ventilation device 4 based on the above. Note that when the number of stoves or the like driven in the heating unit 31 of the cooking device 3 is large and when the heating power of the stove or the like of the heating unit 31 is large, the air volume of the ventilation device 4 is the driving state of the cooking device 3. Depending on the, it is set to “strong” or “medium” which is a large air volume.

(Control flow)
Next, with reference to FIGS. 2-4, the control flow of the ventilation system 1 by one Embodiment of this invention is demonstrated. This control flow is executed by the control means 27 (see FIG. 2) of the detector 2.

  In the control flow of the ventilation system 1, as shown in FIG. 3, in step S <b> 1, the controller 27 determines whether or not the cooking device 3 is in a driving state. When the cooking device 3 is in the driving state, the ventilation device 4 is controlled by the control means 27 so that the air volume according to the driving state of the cooking device 3 is obtained in step S2. Then, the process returns to step S1. That is, when the cooking device 3 is driven, the ventilation device 4 is always controlled so that the air volume according to the driving state of the cooking device 3 is obtained.

  If the cooker 3 is not in the driving state in step S1, the dry bulb temperature (temperature) and the relative humidity in the room 500 are acquired from the temperature sensor 215 and the humidity sensor 216 by the control means 27 in step S3. In step S <b> 4, the control unit 27 acquires the absolute humidity of the room 500 based on the temperature and relative humidity of the room 500 and the absolute humidity acquisition map stored in the storage unit 28.

In step S5, the control means 27 determines whether or not the dew condensation determination is stopped. If the control means 27 is not in the dew condensation determination stop state, whether or not the humidity (air condition) in the room 500 satisfies the dew condensation determination condition (the absolute humidity in the room 500 is 7 g / m ³ or less) in step S6. It is determined whether or not. When the control unit 27 is in the dew condensation determination stop state or when the room 500 does not satisfy the dew condensation determination condition, the process proceeds to step S20 described later in FIG. When the dew condensation determination is not stopped and the room 500 satisfies the dew condensation determination condition, in step S7, the control unit 27 switches to the dew condensation determination mode, and time measurement by the dew condensation determination mode timer is started. .

  In step S8, similarly to step S1, the controller 27 determines whether or not the cooking device 3 is in a driving state. When the cooking device 3 is in the driving state, the process proceeds to step S2. When the cooking device 3 is not in the drive state, the temperature and relative humidity of the room 500 are acquired by the control means 27 in step S9. In step S <b> 10, the absolute humidity of the room 500 is acquired by the control unit 27.

  In step S11 and step S12, the control means 27 determines that the humidity (air condition) of the room 500 is greater than the first ventilation determination condition (the absolute humidity of the room 500 is greater than 7 g / m3 and the relative Whether the humidity is 70% RH or higher) or the second ventilation determination condition (the condition that the absolute humidity of the room 500 is higher than 7 g / m 3 and the relative humidity is 65% RH or higher continues for 5 minutes) Is determined. When the room 500 satisfies either the first ventilation determination condition or the second ventilation determination condition, the control unit 27 starts driving the ventilation device 4 in step S13. Thereby, ventilation of the room 500 is started.

  In step S14, as in steps S1 and S8, the controller 27 determines whether or not the cooking device 3 is in a driving state. When the cooking device 3 is in the driving state, the process proceeds to step S2. That is, the driving of the ventilation device 4 based on the driving of the cooking device 3 is prioritized during the execution of the dew condensation determination mode by step S8 and step S14.

  When the cooking device 3 is not in the drive state, in step S15, the control unit 27 determines whether or not one hour has elapsed since the start of the drive of the ventilation device 4. If one hour has not elapsed since the start of driving the ventilation device 4, the process returns to step S14. That is, the driving of the ventilation device 4 is continued. If one hour has elapsed since the start of driving the ventilation device 4, the control means 27 ends the driving of the ventilation device 4 and the condensation determination mode in step S16. Thereafter, it is determined whether or not the dew condensation determination stop condition (relative humidity is 63% RH or more) is satisfied, and the process returns to step S1.

  If the room 500 does not satisfy the first ventilation determination condition and the second ventilation determination condition in steps S11 and S12, respectively, the humidity (air state) of the room 500 is dewed by the control means 27 in step S17. Whether or not the determination condition is satisfied is determined again. When the humidity in the room 500 satisfies the dew condensation determination condition, the controller 27 resets the dew condensation determination mode timer in step S18. Then, the process proceeds to step S19. In step S17, when the humidity in the room 500 does not satisfy the dew condensation determination condition, the process proceeds to step S19.

  In step S19, the control means 27 determines whether or not the timer in the dew condensation determination mode has exceeded 24 hours. If the timer does not exceed 24 hours, the process returns to step S8 and the execution of the dew condensation determination mode is continued. If the timer exceeds 24 hours, the control means 27 ends the condensation determination mode. Then, the process returns to step S1.

  If the dew condensation determination is stopped in step S5, or if the room 500 does not satisfy the dew determination condition in step S6, whether or not the heat burn determination is stopped by the control means 27 in step S20 shown in FIG. Is judged. When the control means 27 is in the heat-burning determination stop state, the process returns to step S1 (see FIG. 3). If the control means 27 is not in the heat-burning determination stop state, the control means 27 causes the control means 27 to control the room 500 based on the temperature and relative humidity of the room 500 and the WBGT acquisition map stored in the storage means 28 in step S21. WBGT is acquired.

  In step S <b> 22, the control unit 27 determines whether the humidity (air condition) of the room 500 satisfies the heat-burning determination condition (the WBGT of the room 500 is 29 ° C. or higher). If the room 500 does not satisfy the heat detection criteria, the process returns to step S1. When the room 500 satisfies the heat-burning determination condition, the control unit 27 switches to the heat-burning mode in step S23, and the drive of the ventilation device 4 is started. In step S23, as in steps S1, S8, and S14, the control means 27 determines whether or not the cooking device 3 is in a driving state. When the cooking device 3 is in the driving state, in step S25, the ventilation device 4 is controlled by the control means 27 so that the air volume according to the driving state of the cooking device 3 is obtained, as in step S2. Then, the process returns to step S1. Thereby, during execution of the heat-burning mode, the driving of the ventilation device 4 based on the driving of the cooking device 3 is prioritized.

  When the cooking device 3 is not in the driving state, the temperature and relative humidity of the room 500 are acquired by the control means 27 in step S26. In step S27, the control unit 27 acquires the WBGT of the room 500.

  In step S28, the control means 27 determines whether the humidity (air condition) of the room 500 satisfies the heat-burning mode release condition (the WBGT of the room 500 is less than 28 ° C.) during execution of the heat-burning mode. . If the room 500 does not satisfy the heat-burning mode release condition, in step S29, the control means 27 determines whether or not one hour has passed since the start of the heat-burning mode. If one hour has not elapsed since the start of the heat-burning mode, the process returns to step S24. That is, the driving of the ventilation device 4 is continued. When the room 500 satisfies the heat-burning mode release condition, or when one hour has elapsed from the start of the heat-burning mode, in step S30, the drive of the ventilation device 4 is ended by the control means 27 and the heat-burning is performed. The mode is terminated. Thereafter, it is determined whether or not the heat-burning determination stop condition (heat-burning mode release condition) is satisfied, and the process returns to step S1 (see FIG. 3).

(Effect of this embodiment)
In the present embodiment, the following effects can be obtained.

  In the present embodiment, as described above, the control unit 27 is configured to switch to the dew condensation determination mode when the air state of the room 500 satisfies the dew condensation determination condition. Then, the control unit 27 is configured to ventilate the room 500 when the air condition in the room 500 satisfies the first ventilation determination condition or the second ventilation determination condition different from the condensation determination condition during execution of the condensation determination mode. The ventilation device 4 is configured to be controlled. As a result, the condensation determination condition is set to a condition that can determine whether or not condensation is likely to occur, and whether the first ventilation determination condition or the second ventilation determination condition is highly likely to actually occur By setting the condition whether or not it is possible to determine whether or not the condensation determination condition is in a state in which it is determined in advance that the condensation can occur to some extent, the condensation is actually applied to the first ventilation determination condition or the second ventilation determination condition. It is determined whether or not there is a high possibility of occurrence. As a result, it is determined that there is a high possibility that condensation will occur in a state where condensation is unlikely to occur, and ventilation of the room 500 can be suppressed from starting. Therefore, unnecessary driving of the ventilation device 4 can be suppressed while suppressing the occurrence of condensation.

  In the present embodiment, the first ventilation determination condition and the second ventilation determination condition are both configured by conditions that do not satisfy the dew condensation determination condition. As a result, the condensation determination condition is set to a condition where condensation is unlikely to occur at the present time but can easily occur if the situation changes, and the first ventilation determination condition and the second ventilation determination condition are set. It is possible to set the ventilation judgment condition to a condition (a condition different from the condensation judgment condition) that can determine whether or not the situation has changed from the condensation judgment condition and the possibility that condensation will easily occur is high. it can. As a result, a range in which it is possible to determine that it is possible to suppress unnecessary driving of the ventilating device 4 while suppressing the occurrence of condensation based on the dew condensation determination condition and the first ventilation determination condition or the second ventilation determination condition. Can be further narrowed. Therefore, unnecessary driving of the ventilation device 4 can be suppressed more reliably while suppressing the occurrence of condensation.

  In the present embodiment, the dew condensation determination condition, the first ventilation determination condition, and the second ventilation determination condition are configured by conflicting conditions. As a result, the first ventilation determination condition and the second ventilation determination condition can be reliably set to a state in which the situation has changed with the dew condensation determination condition, so that it is unnecessary while suppressing the occurrence of dew condensation more effectively. Driving of the ventilation device 4 can be suppressed.

  In the present embodiment, the dew condensation determination condition includes a first absolute humidity condition related to absolute humidity. The first ventilation determination condition and the second ventilation determination condition include a second absolute humidity condition related to absolute humidity and a relative humidity condition related to relative humidity (first relative humidity condition and second relative humidity condition). Accordingly, it is possible to drive unnecessary ventilation equipment 4 while suppressing the occurrence of condensation based on the absolute humidity condition and the relative humidity condition in which it is easy to determine whether or not condensation can occur and the actual possibility of condensation. It is possible to easily drive the ventilation device 4 so as to suppress the above.

Further, in the present embodiment, by setting the absolute humidity as the air condition of the room 500 to a predetermined absolute humidity or less (7 g / m ³ ) as the dew condensation condition, the air condition of the room 500 is changed. In a low temperature state (a state in which the amount of water (saturated water vapor amount) that can be held in the air is small), the condensation determination condition can be set so that the condensation determination condition can be easily satisfied. As a result, the dew condensation determination condition can be set to a condition that can determine whether or not dew condensation can occur.

  In the present embodiment, the relative humidity condition of the first ventilation determination condition is that the relative humidity as the air state of the room 500 is equal to or higher than a predetermined relative humidity (70% RH or higher). Further, the relative humidity condition of the second ventilation determination condition is that the relative humidity as the air state of the room 500 is equal to or higher than a predetermined relative humidity (65% RH or higher). As a result, in the state where the dew condensation determination mode is being executed and the room 500 is at a low temperature, the air state in the room 500 is in a state where there is no room for the amount of water that can be held in the air, and moisture that cannot be held in the air is condensed. When it is easy to do, the first ventilation determination condition and the second ventilation determination condition can be set so that the first ventilation determination condition or the second ventilation determination condition can be easily satisfied. As a result, it is possible to make the first ventilation determination condition and the second ventilation determination condition a condition that can determine whether or not there is a high possibility that condensation will actually occur.

  In the present embodiment, the first ventilation determination condition and the second ventilation determination condition include not only the relative humidity condition but also the second absolute humidity condition related to the absolute humidity as in the dew condensation determination condition. Thereby, the dew condensation determination condition, the first ventilation determination condition, and the second ventilation determination condition can be closely associated with each other based on the absolute humidity. As a result, unnecessary ventilation device 4 is driven while more reliably and easily suppressing the occurrence of condensation based on the closely related dew condensation determination condition, the first ventilation determination condition, and the second ventilation determination condition. Can be suppressed.

  Further, in the present embodiment, the control unit 27 causes the room 500 when the air condition in the room 500 satisfies one of the first relative humidity condition and the second relative humidity condition during execution of the dew condensation determination mode. The ventilation device 4 is configured to be controlled to start ventilation. Thereby, generation | occurrence | production of dew condensation can be suppressed more reliably.

  Further, in the present embodiment, the control unit 27 is configured to continue to execute the condensation determination mode for 24 hours after the air condition in the room 500 finally satisfies the condensation determination condition. That is, when the air condition in the room 500 newly satisfies the condensation determination condition during the execution of the condensation determination mode, the execution of the condensation determination mode is extended for 24 hours from that point. As a result, by satisfying the dew condensation determination condition, it is determined that the environment is likely to cause dew condensation in the room 500 such as in winter, and the dew determination mode is executed. Even if the condition is not satisfied, it can be determined that it is still winter time if the dew condensation determination condition is satisfied again within 24 hours. As a result, the condensation determination mode can be continuously executed over a long period of time in an environment where condensation is likely to occur in the room 500 such as in winter.

  Moreover, in this embodiment, the control means 27 is comprised so that control of the ventilator 4 based on the drive state of the cooking appliance 3 may be given priority over control of the ventilator 4 during execution of the dew condensation determination mode. Thereby, when the cooker 3 is driven, the ventilator 4 is driven to release the heat of the cooker 3 from the room 500 to the outside regardless of the control of the ventilator 4 during the execution of the dew condensation determination mode. At the same time, new air can be taken into the room 500 from the outside. Thereby, the heating in the cooking appliance 3 can be performed safely.

  In the present embodiment, the detector 2 including the temperature sensor 215, the humidity sensor 216, and the control means 27 is provided separately from the ventilation device 4. And the control means 27 of the detector 2 is changed from the detector 2 to the ventilation device 4 when the air state of the room 500 satisfies the first ventilation determination condition or the second ventilation determination condition during the execution of the dew condensation determination mode. On the other hand, the ventilation device 4 is controlled so as to start ventilation of the room 500 by performing communication. Thus, unlike the case where the temperature sensor 215, the humidity sensor 216, and the control means 27 are arranged in one device having the ventilation device 4, the temperature sensor 215 and the humidity sensor 216 are separately provided at positions away from the ventilation device 4. Therefore, the temperature sensor 215 and the humidity sensor 216 can be arranged at a position where the air condition of the room 500 can be appropriately determined. Further, the temperature sensor 215, the humidity sensor 216, and the control means 27 are provided in the detector 2, so that the air condition in the room 500 detected by the temperature sensor 215 and the humidity sensor 216 can be controlled without communication to the outside. Can be sent to.

  In the present embodiment, the ventilation system 1 ventilates the room 500 when the first ventilation determination condition or the second ventilation determination condition is satisfied during the execution of the dew condensation determination mode. Moreover, in the ventilation system 1, the room 500 is ventilated in the heat-burning mode. Thereby, since it is possible to suppress the occurrence of dew condensation and the heat-burning state during a time period when the ventilation device 4 is not driven based on the driving state of the cooking device 3, the ventilation device 4 is effectively used. can do.

[Example]
Next, the ventilation experiment performed in order to confirm the effect of this invention is demonstrated.

In the ventilation experiment, the ventilation system 1 of the above embodiment was used. Here, the dew condensation determination condition of the control means 27 is the first absolute humidity condition that the absolute humidity of the room 500 is 7 g / m ³ or less. In addition, the first ventilation determination condition of the control means 27 includes a second absolute humidity condition that the absolute humidity in the room 500 is greater than 7 g / m ³ and a first relative humidity condition that the relative humidity is 70% RH or more. Both conditions were met. In addition, the second ventilation determination condition of the control means 27 includes a second absolute humidity condition that the absolute humidity in the room 500 is greater than 7 g / m ³ and a state where the relative humidity is 65% RH or more and continues for 5 minutes. 2 Relative humidity conditions were satisfied. In the room 500, a heater for adjusting the dry bulb temperature (air temperature) of the room 500 and a humidifier for adjusting the relative humidity of the room 500 are arranged.

In the ventilation experiment, the outdoor temperature was set to 5 ° C., and the temperature in the room 500 was set to 20 ° C. That is, the outdoor temperature was set to the temperature of the winter season. Here, since the first absolute humidity condition (condensation determination condition is satisfied) that the absolute humidity of the room 500 is 7 g / m ³ or less when the temperature of the room 500 approaches the outdoor temperature, in this experiment, the condensation determination condition Ventilation experiment was conducted on the assumption that the control means 27 is executing the dew condensation determination mode. In addition, by setting the temperature of the room 500 to 20 ° C., when the first relative humidity condition (70% RH) and the second relative humidity condition (65% RH) are satisfied, the second absolute humidity condition (the room 500 Ventilation experiments were conducted in such a manner that the absolute humidity of the water was inevitably higher than 7 g / m ³ .

  And the heater was stopped and the humidifier was driven in the state which raised the temperature of the room 500 from 20 degreeC using the heater. Then, a change in the humidity of the room 500 when the ventilation device 4 is driven while satisfying the first ventilation determination condition or the second ventilation determination condition (first relative humidity condition or second relative humidity condition) is observed. did. The result of the ventilation experiment is shown in FIG.

  As a result of the ventilation experiment, as shown in FIG. 5, the relative humidity of the room 500 is 60% RH while the second ventilation determination condition (second relative humidity condition) is satisfied and the ventilation device 4 is driven. It became the following. Further, even after the ventilation device 4 was driven for 1 hour and the drive of the ventilation device 4 was terminated, the relative humidity of the room 500 was kept at 60% RH or less for 1 hour or more. As a result, it can be confirmed that the relative humidity of the room 500 can be reduced by driving the ventilation device 4 and that the relative humidity can be kept stable to some extent even after the driving of the ventilation device 4 is finished. It was. Even when the first ventilation determination condition (first relative humidity condition) is satisfied, the interior of the room 500 is similar to the case where the second ventilation determination condition (second relative humidity condition) illustrated in FIG. 5 is satisfied. It is considered possible to reduce the relative humidity.

Further, the second condition may be configured by only one of an absolute humidity condition related to absolute humidity and a relative humidity condition related to relative humidity. Further, the second condition may be configured to include, for example, an air temperature condition in addition to the absolute humidity condition and the relative humidity condition.

  In the above embodiment, when the control unit 27 satisfies either the first ventilation determination condition or the second ventilation determination condition (when either of the two conditions is satisfied), the room 500 is ventilated. Although the example which controls the ventilation apparatus 4 (ventilation means) to perform was shown, this invention is not limited to this. In the present invention, when the control means satisfies any one of the three or more conditions, the ventilation means may be controlled to ventilate the room, or when one condition is satisfied. The ventilation means may be controlled to ventilate the room.

In this invention, you may comprise so that the numerical value of 1st condition and 2nd condition can be changed from the preset value. For example, you may comprise a ventilation system so that the user or the installation company of a ventilation system can change the numerical value of 1st condition and 2nd condition. Further, for example, a learning function may be provided in the control means. In this case, the ventilation system may be configured so that the numerical values of the first condition and the second condition are appropriately changed by learning, for example, when the user inputs the presence / absence of occurrence of condensation into the control means.

  In the above embodiment, the example in which the dew condensation determination mode continues for 24 hours (first period) after the last time the dew condensation determination mode is satisfied has been described, but the present invention is not limited to this. In the present invention, the time “24 hours” is merely an example, and the first period may be changed as appropriate. In addition, the ventilation system may be configured so that the dew condensation determination mode continues for the first period after the dew condensation determination condition is satisfied first, not after the dew condensation determination mode is satisfied last.

  Moreover, in the said embodiment, while driving the ventilation apparatus 4 (ventilation means) for 1 hour continuously during execution of the dew condensation determination mode, the drive of the ventilation apparatus 4 is terminated. Although the example configured to end the condensation determination mode is shown, the present invention is not limited to this. In the present invention, the time “1 hour” is merely an example, and may be changed as appropriate. Further, during the execution of the dew condensation determination mode, if any ventilation interruption condition is satisfied, the driving of the ventilation means may be interrupted, and if the second condition is satisfied again, the interrupted driving of the ventilation means may be resumed. . Further, during the execution of the condensation determination mode, when any ventilation interruption condition is satisfied, the driving of the ventilation means may be terminated and the condensation determination mode may be terminated.

Although an example is shown in which the dew condensation determination mode is not executed for 3 hours (dew condensation determination stop state), the present invention is not limited to this. In the present invention, the control means may be in a dew condensation determination stopped state for less than 3 hours or longer than 3 hours after the end of driving of the ventilation means. Moreover, you may comprise a control means so that it may not switch to a dew condensation determination stop state.

  Moreover, although the said embodiment showed the example comprised by the conditions which dew condensation determination conditions (1st condition), 1st ventilation determination conditions, and 2nd ventilation determination conditions (2nd condition), this invention is shown. It is not limited to this. In the present invention, the first condition and the second condition do not need to be configured under the contradictory conditions. In this case, it is preferable to configure the second condition by a condition that does not satisfy the first condition. Further, the second condition may be configured by a condition that satisfies the first condition. In this case, the second condition needs to be narrower than the first condition.

  In the above-described embodiment, an example in which the heat-burning mode is provided in the control unit 27 separately from the dew condensation determination mode has been described, but the present invention is not limited to this. In the present invention, the heating mode may not be provided in the control means.

  Moreover, although the ventilation system 1 was comprised in the said embodiment from the detector 2 containing the control means 27, the cooking device 3 (heating means), and the ventilation apparatus 4 (ventilation means), this invention was shown.
