  The air blowing direction setting unit 5b includes a motor that can rotate the air blowing unit 5a by, for example, 180 ° around the longitudinal axis of the air blowing unit 5a. In addition, the suction port (not shown) of the same shape as the blower outlet 5c is provided in the other side of the blower outlet 5c of the ventilation part 5a.

  When the controller 4 detects that the operation of the air conditioner is heating from the state signal, the controller 4 controls the air blowing direction setting unit 5b so that the air blown by the air blowing unit 5a is directed to the indoor wall. When it is detected that the operation is cooling, the blowing direction setting unit 5b is controlled so that the blowing of the blowing unit 5a is directed to the floor.

Here, the air blowing direction during the cooling operation and the heating operation will be described in detail with reference to FIGS. 2 and 3.
FIG. 2 is a diagram illustrating a blowing direction during a cooling operation in summer in the air conditioning system, and FIG. 3 is a diagram illustrating a blowing direction during a heating operation in winter in the system.
During the cooling operation, as shown in FIG. 2, the blower 5a of the blower 5 is fixed and operated at an angle within a second angle range (for example, a range of −80 ° to 80 °) with respect to the vertical direction. To do. Further, during the heating operation, as shown in FIG. 3, the blower 5 a of the blower device 5 has a first angle range (for example, a range of −80 ° to −100 ° and a range of 80 ° to 100 ° with respect to the vertical direction). ) Operates with a fixed angle. The angle setting of the blowing unit 5a is performed by the blowing direction setting unit 5b.

Next, operation | movement of the air conditioning system of this Embodiment is demonstrated using FIG.2 and FIG.3.
When the cooling operation is selected by operating the remote controller 3, as described above, the outdoor unit 2 of the air conditioner functions as a condenser and the indoor unit 1 functions as an evaporator, and cold air is blown out from the indoor unit 1. At this time, the indoor unit 1 inputs a state signal indicating the cooling operation to the controller 4. When the controller 4 detects from the state signal input via the input unit that the operation of the air conditioner is cooling, the air blowing unit 5a of the air blower 5 is set to −80 ° to 80 ° with respect to the vertical direction. While controlling the blowing direction setting unit 5b so as to be fixed at an angle within the angle range, each fan motor of the blowing unit 5a is driven. In this case, the cold air blown out from the indoor unit 1 is sucked from the suction port of the blower 5a and blown out from the blower outlet 5c toward the floor as shown by the arrows in FIG.

  When the heating operation is selected by operating the remote controller 3, the outdoor unit 2 of the air conditioner acts as an evaporator and the indoor unit 1 acts as a condenser, and hot air is blown out from the indoor unit 1. At this time, the indoor unit 1 inputs a state signal indicating a heating operation to the controller 4. When the controller 4 detects that the operation of the air conditioner is heating from the state signal input via the input unit, the blower 5a of the blower 5 is -80 ° to -100 ° with respect to the vertical direction. The air blowing direction setting unit 5b is controlled and each fan motor of the air blowing unit 5a is driven so as to be fixed at an angle within an angle range of 80 ° to 100 °. In this case, the warm air blown from the indoor unit 1 is sucked from the suction port of the blower 5a and blown toward the wall from the blower outlet 5c as shown by the arrows in FIG.

  Further, when the controller 4 detects that the air conditioner has stopped operating from the input state signal during the heating operation, that is, while the air conditioner is in the heating operation, the heating operation is temporarily performed by the indoor temperature control. When the operation is stopped or when the outdoor unit 2 is defrosted, the operation of the blower 5 is stopped. This is because warm air is not blown out from the indoor unit 1. When operating the blower 5 in such a state, the indoor air is circulated by the blower 5 to become cold air, and cool air is sent to the vicinity of the floor surface, giving a cold air feeling to the person in the room, In the present embodiment, as described above, since the operation of the blower 5 is also stopped, the feeling of cold air is not given to the person in the room. In addition, when the operation of the air conditioner is resumed, the blower 5 is started again by the controller 4.

Can be applied directly to the human body, and the air temperature of the blower 5 lowers the sensible temperature. Therefore, it is possible to maintain comfort even if the set temperature of the air conditioner is increased by about 1 to 2 ° C. There is also.

  When the operation of the air conditioner is heating, since the air blowing direction setting unit 5b is controlled so that the air blown by the air blowing unit 5a is directed to the indoor wall, the air conditioner is not directly applied to the human body. The warmed air can be circulated and the temperature near the floor also rises, so the temperature difference in the height direction can be eliminated. Moreover, when the temperature near the floor rises, the room can be uniformly heated without wastefully operating the air conditioner, which has an energy saving effect.

  In addition, when the air conditioner is in the heating stop operation, when the operation is stopped by the indoor temperature control or when the outdoor unit 2 is in the defrosting operation state, the operation of the blower 5 is stopped. , No feeling of cold wind is given to the person, no cooling air is circulated, and heating efficiency is not lowered.

  In the first embodiment, during the heating operation, when it is detected that the air conditioner has stopped operating from the input state signal, the operation of the blower 5 is also stopped. In addition, it may be determined from the temperature of the air blown out from the indoor unit 1 whether or not the air conditioner has stopped operating. A temperature sensor, which is a temperature detection means for detecting the temperature of the air, is provided, for example, in the blowing direction setting unit 5b, and the air conditioner has stopped operating from the input state signal and the detected temperature of the temperature sensor during heating operation. Determine whether or not. Regarding the temperature, it is determined that the air conditioner has stopped operating when the temperature detected by the temperature sensor has dropped to a predetermined temperature.

  When it is determined whether or not the air conditioner has stopped operating from the state signal and the temperature detected by the temperature sensor, it is possible to more accurately determine whether the air conditioner is operating or stopped, and the blower The maximum capability as an auxiliary device of the air conditioner can be extracted without wasting 5.

Embodiment 2. FIG.
In the first embodiment, the operation of the air conditioner is cooling or heating, or the operation stop state by temperature control during the heating operation or the operation state such as during the defrosting operation of the outdoor unit 2 of the air conditioner is determined to perform circulation.

For example, an infrared sensor that detects the heat of the indoor space is provided in the blowing direction setting unit 5b of the blowing device 5 to measure the temperature of the floor surface or the wall surface, or to detect a place where a person is present, and to detect the detected information as a controller 4 The controller 4 determines a place with a high heat load based on the input detection information, and during the cooling operation, a blower is provided so that cold air is actively blown to a place with a high heat load, that is, a place where a person is present. The air blower 5a of the blower 5 is operated so that the warm air is blown away from the place where people are present during heating operation. The operation is fixed at an angle within an angle range of 1.
As described above, since the cool air is actively blown to the place where the person is present during the cooling operation, the sensible temperature can be further lowered and the comfort can be maintained. In addition, during the heating operation, warm air is blown away from places where people are present, so that the living space can be efficiently air-conditioned without impairing the comfort of the resident without giving a feeling of cold air. Is possible.

  Although an infrared sensor for detecting radiant heat has been described as an example, temperature, humidity, human sensor, and the like can be considered as sensors capable of measuring the indoor environment, and the same effect can be obtained by using any sensor. In addition, although it has been described that the infrared sensor is provided in the blowing direction setting unit 5 b of the blower 5, the infrared sensor may be provided in the indoor unit 1 and detection information from the infrared sensor may be input to the controller 4. .
