Moreover, the control part 8 is arrange | positioned inside the housing | casing which forms the external shape of the air blower controller 3, and it has the structure which provided the operation part 7 on the surface of the housing | casing.
The control unit 8 is electrically connected to the operation unit 7, the first temperature sensor 9 for detecting the indoor temperature, and the second temperature sensor 10 for detecting the outdoor temperature by wire or wirelessly, as shown in FIG. Based on the operation command from the operation unit 7, the first temperature detected by the first temperature sensor 9, and the second temperature detected by the second temperature sensor 10, the ON / OFF control of the operation of the first blower 2 or the air volume Make adjustments.

  The first temperature sensor 9 is disposed indoors, and the second temperature sensor 10 is disposed outdoors. In addition, if the 2nd temperature sensor 10 is arrange | positioned in the suction inlet vicinity of the 1st air blower 2, it can detect the exact temperature of the air taken in indoors. In addition, when the building 1 itself has heat, the temperature of the outside air can be detected more accurately if the building 1 is disposed at a position slightly away from the building 1. Therefore, the second temperature sensor 10 may be appropriately changed according to the situation. In addition, the operation unit 7 and the control unit 8 of the blower controller 3 according to the first embodiment are arranged so as to be accommodated in the same housing, but this is not restrictive, and the operation unit 7 and the operation unit 7 may be arranged in different places. May be carried with a remote control.

The operation unit 7 of the blower controller 3 will be described with reference to FIG. FIG. 3 is a diagram showing an operation unit of the blower controller according to Embodiment 1 of the present invention.
As shown in FIG. 3, the operation unit 7 of the blower controller 3 includes a digital display unit 11, a setting switching unit 12, an operation switching unit 13, a reset button 14, a mode selection unit 15, and a test operation display unit 16. The digital display unit 11 displays the time at the normal time, and displays the setting conditions and the like when setting or changing the automatic operation described later. The setting switching unit 12 is used when changing the time, setting during automatic driving, or the like. Further, the setting switching unit 12 is a dial type, and is rotated to display the next candidate on the digital display unit 11 and press the setting switching unit 12 for determination. The operation switching unit 13 is used when selecting automatic operation or continuous operation. Automatic operation is a method in which a user or the like sets an operation mode in advance and automatically operates based on the setting conditions.Continuous operation is an operation mode that is set every time a user uses the setting condition. Based on driving. The reset button 14 is used when it is desired to initialize time, automatic driving setting, and the like. The mode selection unit 15 is used when selecting an operation mode. The switch of the mode selection unit 15 is constituted by a projection protruding from the surface of the operation unit 7. For example, the switch is turned off when the projection is lowered downward, and is turned on when the projection is raised upward. In the first embodiment, when 1: timer operation, 2: night purge operation, 3: temperature adjustment operation, 4: humidity adjustment operation, and storage unit 17 (not shown) in control unit 8 are allocated. For example, when “2” is raised to the upper side, the night purge operation is executed. The night purge operation is an operation in which, for example, in the cooling season, night air having a low temperature is taken into the room in order to reduce a load at the start-up of the next morning cooling. The test operation display unit 16 is lit when a test operation is being performed.

Next, a method for controlling the first blower 2 by the blower controller 3 will be described.
When “continuous” of the operation switching unit 13 of the operation unit 7 and “3” of the mode selection unit 15 are selected by the user or the like, the control unit 8 performs “continuous operation” and “temperature adjustment operation”. A command is made. Subsequently, the control unit 8 acquires temperature information from the first temperature sensor 9 and the second temperature sensor 10, and drives the electric motor 5 to the first blower 2 when determining that the first temperature is higher than the second temperature. Give a directive to When the impeller 6 is rotated by driving the electric motor 5, cool outdoor air is taken into the room. By taking outdoor cool air into the room, it can be replaced with warm air in the room, so that the temperature in the room can be lowered. When the first temperature is equal to the second temperature or the first temperature is constant for a certain period, the control unit 8 has no effect of lowering the indoor temperature even if the first blower 2 is operated further. The first blower 2 is instructed to stop driving the electric motor 5 and the operation of the first blower 2 is stopped. The temperature difference between the room and the room can be arbitrarily set to realize more efficient operation under various conditions.

  In this way, the control unit 8 can reduce the temperature difference between the room and the outdoors by controlling the operation of the first blower 2 so that the difference between the first temperature and the second temperature is small. Therefore, for example, in the summer, when the outdoor is cooler than the room, the indoor temperature can be lowered without using an air conditioner. When the temperature difference between the room and the room is large, the temperature difference between the room and the room can be quickly eliminated by increasing the air volume of the first blower.

  Moreover, since the first blower 2 can be operated at a predetermined time by providing the timer controller 3 with the timer function, it is possible to perform the night purge operation. Hereinafter, when the user operates the setting switching unit 12 to set the time setting of the timer to AM 4:00 to AM 7:00, the indoor temperature setting to 30 ° C. or more, and the outdoor temperature setting to less than 25 degrees A method for controlling the first blower 2 by the blower controller 3 will be described with reference to FIG. FIG. 4 is a diagram showing an ON / OFF state of the blower in the night purge operation according to Embodiment 1 of the present invention.

  When “automatic” of the operation switching unit 13 of the operation unit 7 and “2” of the mode selection unit 15 are selected by the user or the like, the control unit 8 performs “automatic operation” and “night purge operation”. A command is made. As shown in FIG. 4, the control unit 8 starts the night purge operation from AM 4:00 by receiving time information from the timer. When the night purge operation is started, the control unit 8 acquires temperature information from the first temperature sensor 9 and the second temperature sensor 10. When the controller 8 determines that the first temperature detected by the first temperature sensor 9 is 30 ° C. or higher and the second temperature detected by the second temperature sensor 10 is 25 ° C. or lower, the first blower 2 is given a command to drive the electric motor 5. And the impeller 6 rotates by the drive of the electric motor 5, and the 1st air blower 2 will be in an operation state. (AM4: 00 to AM6: 00 in FIG. 3). When cool air is taken into the room, the temperature in the room gradually decreases. When the first temperature becomes 30 ° C. or lower, the controller 8 gives a command to the first blower 2 to stop driving the electric motor 5 and stops the operation of the first blower 2. (AM6: 0 to AM6: 30 in the figure). Moreover, the operation of the first blower 2 is stopped when the outdoor temperature gradually rises and the second temperature becomes higher than 25 ° C. At AM 7:00, the night purge operation is stopped. That is, the conditions for the control unit 8 to operate the first blower 2 in the night purge operation are when AM 4:00 to AM 7:00, the first temperature is 30 ° C. or more, and the second temperature is less than 25 ° C.

  By performing such a night purge operation at dawn in the summer, cool air can be taken into the room, so that the air conditioning load when using the air conditioner can be reduced.

  The blower controller 3 according to Embodiment 1 of the present invention operates the first blower 2 based on the first temperature detected by the first temperature sensor 9 and the second temperature detected by the second temperature sensor 10. Since the first blower 2 can be operated when ventilation is effective for controlling, it is possible to perform more efficient ventilation. Furthermore, the operation time can be reduced by omitting the useless operation of the first blower 2, and there is also an energy saving effect.

Embodiment 2
Although the air blower controller 3 according to Embodiment 1 of the present invention includes one air supply first air blower 2, the air blower controller 3 according to Embodiment 2 is the air supply first air supply. In addition to the blower 2, a second blower 18 for exhaust is provided. Since the other parts are the same as the configuration according to the first embodiment, only the differences from the first embodiment will be described in the second embodiment. The second embodiment will be described with reference to FIG. FIG. 5 is a diagram in which a blower controller according to Embodiment 2 of the present invention is arranged in a building.

  As shown in FIG. 5, a first air blower 2 for taking in outdoor air into the room and a second blower 18 for discharging indoor air to the outside, the first blower 2 and the second blower on the wall surface of the building 1. 18 is provided with a blower controller 3 that performs ON / OFF of operation 18 or adjustment of air volume. The blower controller 3 according to Embodiment 2 is wired or wirelessly connected to the first blower 2 and the second blower 18, the first temperature sensor 9 that detects the indoor temperature, and the second temperature sensor 10 that detects the outdoor temperature. Based on the first temperature detected by the first temperature sensor 9 and the second temperature detected by the second temperature sensor 10, which are electrically connected, ON / OFF of the operation of the first blower 2 and the second blower 18 or Adjust the air flow.

  When only the first blower 2 is operated as in the first embodiment, as a result of taking outdoor air into the room, ventilation is performed by exhaling the indoor air in the form of being pushed out. However, when the first blower 2 and the second blower 18 are further provided on the wall surface as in the second embodiment and the first blower 2 and the second blower 18 are operated, the air staying in the room is also positive at the same time. Is exhaled outdoors. For this reason, ventilation volume can be increased significantly.

  By using the blower controller 3 according to the second embodiment, the first blower 2 and the second blower 18 can be operated. Therefore, in addition to the effect of the first embodiment, air can be rapidly ventilated, for example, when the temperature difference between the outdoor and the indoor is large.

Embodiment 3
The fan controller 3 according to the first embodiment and the second embodiment is provided with a temperature sensor, thereby efficiently ventilating indoor and outdoor air, but for the fan according to the third embodiment. The controller 3 includes a humidity sensor 19 in addition to the temperature sensor. The third embodiment will be described with reference to the drawings. FIG. 6 is a diagram in which a blower controller according to Embodiment 3 of the present invention is arranged in a building, and FIG. 7 is a block diagram illustrating a control unit according to Embodiment 3 of the present invention.

As shown in FIG. 6, on the wall surface of the building 1, there are a first blower 2 for supplying air that takes outdoor air into the room, and a blower controller 3 that performs ON / OFF of the operation of the first blower 2 or adjustment of the air volume. Is provided. The blower controller 3 includes an operation unit 7 operated by a user and a control unit 8 that controls the operation of the first blower 2. Moreover, the control part 8 is arrange | positioned inside the housing | casing which forms the external shape of the air blower controller 3, and it has the structure which provided the operation part 7 on the surface of the housing | casing.
The blower controller 3 is wired or wirelessly connected to the operation unit 7, the first temperature sensor 9 for detecting the indoor temperature, the second temperature sensor 10 for detecting the outdoor temperature, and the humidity sensor 19 for detecting the outdoor humidity. As shown in FIG. 7, the operation command from the operation unit 7, the first temperature detected by the first temperature sensor 9, the second temperature detected by the second temperature sensor 10, and the humidity sensor 19 On / off control of the operation of the first blower 2 or adjustment of the air volume is performed based on the first humidity detected by.

  The first temperature sensor 9 is disposed indoors, and the second temperature sensor 10 and the humidity sensor 19 are disposed outdoors. In addition, if the 2nd temperature sensor 10 is arrange | positioned in the suction inlet vicinity of the 1st air blower 2, it can detect the exact temperature of the air taken in indoors. Further, when the building 1 itself has heat, the temperature of the outside air can be detected more accurately if the building 1 is disposed at a position slightly away from the building 1. If the humidity sensor 19 is disposed in the vicinity of the suction port of the first blower 2, it can detect the exact humidity of the air taken into the room. Moreover, when the wall surface of the building 1 is dewed or the like, the humidity of the outside air can be detected more accurately if it is arranged at a position slightly away from the building 1. Therefore, the second temperature sensor 10 and the humidity sensor 19 may be appropriately changed according to the situation. The operation unit 7 and the control unit 8 of the blower controller 3 according to the third embodiment are arranged so as to be housed in the same housing, but this is not restrictive, and the operation unit 7 may be arranged at a different location. It may be portable. The configuration of the remote controller is the same as that shown in FIG.

Next, a method for controlling the first blower 2 by the blower controller 3 will be described.
When “continuous” of the operation switching unit 13 of the operation unit 7 and “4” of the mode selection unit 15 are selected by the user or the like, the control unit 8 performs “continuous operation” and “humidity adjustment operation”. A command is made. Subsequently, the control unit 8 obtains humidity information from the humidity sensor 19, and gives a command to drive the electric motor 5 to the first blower 2 when it is determined that the first humidity is lower than the threshold value A. When the impeller 6 is rotated by the drive of the electric motor 5, the outdoor dry air is taken into the room. By taking outdoor dry air into the room, it can be replaced with moist air in the room, so that the humidity in the room can be lowered. When the first humidity becomes the threshold value B (threshold value B ≧ threshold value A), the control unit 8 determines that there is no effect of lowering the indoor humidity even if the first blower 2 is operated further. A command to stop driving of the electric motor 5 is given, and the operation of the first blower 2 is stopped. Note that the threshold A and the threshold B can be freely set by the user, and more efficient driving can be realized under various conditions.

  The controller 8 can reduce the indoor humidity by controlling the operation of the first blower 2 based on the first humidity. Thus, for example, even when a building is sensitive to moisture, the indoor humidity can be lowered without using a dehumidifier or the like. Further, since it is possible to suppress the inhalation of rain into the room when it is raining, it is possible to protect what is arranged in the building 1 from rain water.

  Moreover, since the first blower 2 can be operated at a predetermined time by providing the timer controller 3 with the timer function, it is possible to perform the night purge operation. Hereinafter, the user operates the setting switching unit 12 to set the timer time setting to AM 4:00 to AM 7:00, the indoor temperature setting to 30 ° C. or more, the outdoor temperature setting to less than 25 ° C., and the humidity setting to 60%. A control method of the first blower 2 by the blower controller 3 in the case of less than RH will be described with reference to FIG. FIG. 8 is a diagram showing an ON / OFF state of the blower in the night purge operation according to Embodiment 3 of the present invention.

  When “automatic” of the operation switching unit 13 of the operation unit 7 and “2” of the mode selection unit 15 are selected by the user or the like, the control unit 8 performs “automatic operation” and “night purge operation”. A command is made. As shown in FIG. 8, the control unit 8 starts the night purge operation from AM 4:00 by receiving time information from the timer. When the night purge operation is started, the control unit 8 acquires temperature information and humidity information from the first temperature sensor 9, the second temperature sensor 10, and the humidity sensor 19. Subsequently, the control unit 8 detects that the first temperature detected by the first temperature sensor 9 is 30 ° C. or higher, the second temperature detected by the second temperature sensor 10 is 25 ° C. or lower, and the first temperature detected by the humidity sensor 19. When it is determined that the humidity is less than 60% RH, a command to drive the electric motor 5 is given to the first blower 2. And the impeller 6 rotates by the drive of the electric motor 5, and the 1st air blower 2 will be in an operation state. (AM4: 00 to AM4: 30 in FIG. 8). As cool dry air is taken into the room, the room is gradually filled with dry air and the temperature of the room decreases. Then, for example, when the rain changes due to weather, the outdoor relative humidity increases. When the first humidity exceeds 60% RH, the first temperature is 30 ° C. or higher and the second temperature is 25 ° C. or lower. However, the control unit 8 gives the first blower 2 a command to stop driving the electric motor 5 and stops the operation of the first blower 2. (AM4: 30 to AM5: 30 in FIG. 8). When the weather recovers and clears, the outdoor relative humidity decreases, the first humidity is again 60% RH or less, the first temperature is 30 ° C or higher, and the second temperature is 25 ° C or lower. The control unit 8 gives a command to drive the electric motor 5 to the first blower 2 (AM5: 30 to AM6: 00 in FIG. 8). Even if the first humidity is 60% RH or less, the room temperature decreases and the first temperature falls below 30 ° C, or the outdoor temperature gradually rises and the second temperature rises above 25 ° C. The controller 8 gives the first blower 2 a command to stop driving the electric motor 5 and stops the operation of the first blower 2. (AM6: 00 to AM 7:00 in FIG. 8). At AM 7:00, the night purge operation is stopped. That is, the conditions for the control unit 8 to operate the first blower 2 in the night purge operation are AM 4:00 to AM 7:00, the first temperature is 30 ° C. or more, the second temperature is less than 25 ° C., and the first humidity is 60%. This is a case of less than RH. In addition, the above is the control for the night purge operation, but when no time is specified, the first temperature is 30 ° C. or more, the second temperature is less than 25 ° C., and the first humidity is less than 60% RH, The control unit 8 may give a command to stop the drive of the electric motor 5 to the first blower 2 and perform control to stop the operation of the first blower 2. This set temperature is an example, and the user can arbitrarily determine the threshold C for the first temperature and the threshold D for the second temperature according to the situation. The set humidity is also an example, and the user can arbitrarily determine the threshold value E according to the situation.

  By performing such a night purge operation at dawn from the summer night, it is possible to take in cool dry air into the room. For this reason, the interior of the room can be kept dry and the air conditioning load when using the air conditioner can be reduced.

  The blower controller 3 according to Embodiment 3 of the present invention includes a first temperature detected by the first temperature sensor 9, a second temperature detected by the second temperature sensor 10, and a first detected by the humidity sensor 19. Since the operation of the first blower 2 is controlled based on the humidity, the first blower 2 can be operated when ventilation is effective, so that more efficient ventilation can be performed. Furthermore, the operation time can be reduced by omitting the useless operation of the first blower 2, and there is also an energy saving effect.

The blower controller 3 according to the fourth embodiment includes a first blower 2 and a second blower 18, a first temperature sensor 9 that detects an indoor temperature, a second temperature sensor 10 that detects an outdoor temperature, and an outdoor humidity. It is electrically connected to the humidity sensor 19 to be detected in a wired or wireless manner, the first temperature detected by the first temperature sensor 9, the second temperature detected by the second temperature sensor 10, and the first temperature detected by the humidity sensor 19. Based on one humidity, the operation of the first blower 2 and the second blower 18 is turned ON / OFF or the air volume is adjusted.

  When only the first blower 2 is operated as in the third embodiment, the outdoor air is taken in as a result of the outdoor air being taken into the room, and ventilation is performed by being discharged outside the room. However, when the first blower 2 and the second blower 18 are further operated on the wall surface as in the fourth embodiment and the first blower 2 and the second blower 18 are operated, the air that is retained in the room at the same time as the outdoor air is taken in. Is actively expelled out of the room. For this reason, the amount of ventilation in the room can be greatly increased.

  By using the blower controller 3 according to the fourth embodiment, the first blower 2 and the second blower 18 can be operated. Therefore, in addition to the effects of the third embodiment, air can be rapidly ventilated, for example, when the temperature difference between the outdoor and the indoor is large.
