Description

The present invention relates to an air conditioner that performs a cooling operation and a dehumidifying operation.

Some indoor units of an air conditioner include a main unit and a fan unit attached to the side of the main unit. Inside the main unit, a heat exchanger and a blower fan are arranged, and the blower fan rotates so that room air is sucked into the main unit. The sucked air is conditioned air generated by heat exchange with the refrigerant in the heat exchanger and blown out into the room. In addition, an auxiliary blower fan is disposed inside the fan unit, and functions as a blower that blows out indoor air sucked into the fan unit. (For example, refer to Patent Document 1.)

In the air conditioner described in Patent Document 1, when performing the cooling operation or the dehumidifying operation, the cold air blown from the blower fan is deflected in the horizontal direction by the vertical airflow direction plate and blown out, and blown out from the auxiliary blower fan. By adjusting the direction of the fan unit so that the indoor air is blown diagonally downward, the cold air is spread throughout the room, and the indoor air is directly applied to the users in the room, thereby feeling the chills due to the cold air. It offers a moderate coolness without letting it go.

Note that the present invention is not limited to the following embodiments, and various modifications can be made without departing from the spirit of the present invention.

The air conditioner 1 of a present Example is comprised with the indoor unit 10 and the outdoor unit which is not shown in figure. As shown in FIGS. 1, 2, and 4, the indoor unit 10 includes a rectangular parallelepiped main body unit 20 and a pair of fan units 30 provided on the left and right sides of the main body unit 20. An outer panel 23 is disposed on the front surface of the main unit 20. A suction port 21 for taking in indoor air is provided on the top side and the front side of the main unit 20. A front panel 24 is provided at a position facing the suction port 21 on the front side, and the front panel 24 is covered with an outer panel 23. As shown in FIG. 4, a heat exchanger 25 and a blower fan 27 that is a cross flow fan are disposed inside the main unit 20. As the blower fan 27 rotates, room air is sucked into the main unit 20 from the suction port 21. The sucked indoor air is heat-exchanged with the refrigerant in the heat exchanger 25 to generate conditioned air. The generated conditioned air has its wind direction deflected by the upper and lower wind direction plates 29a and 29b, which are the first wind direction deflecting means provided at the air outlet 22 at the lower front of the main unit 20, and is blown into the room from the air outlet 22. The The first wind direction deflecting means may also include left and right wind direction plates (not shown) provided at the air outlet 22 of the main unit 20.

The fan unit 30 will be described with reference to FIGS. 1, 2, 3, and 5. As shown in FIG. 1, the fan unit 30 is disposed so as to be accommodated in side fan covers 35 on both sides of the main unit 20. As shown in FIGS. 2 and 5, the fan unit 30 is pivotally supported by the side fan cover 35 so as to rotate about an axis 41 parallel to the rotation axis of the blower fan 27 in the main unit 20. As shown in FIG. 5, the second wind direction deflecting means that is the rotation mechanism 80 of the fan unit 30 includes a motor 80a, a drive gear 80b, a rack 80c, and a roller 80d. The rack 80 c is formed in the cylindrical portion 71 of the fan unit 30 and is arranged in an arc shape along the cylindrical surface 72 of the cylindrical portion 71. The drive gear 80b meshes with the rack 80c, and the fan unit 30 rotates by rotating the drive gear 80b with the motor 80a. The turning mechanism 80 deflects the indoor air blown from the fan unit 30 up and down. A plurality of rollers 80d are arranged at equal distances with respect to the axis 41, and the fan unit 30 is easily rotated when the drive gear 80b is rotated. The second wind direction deflecting unit includes a left and right wind direction plate 36 provided at the auxiliary air outlet 32 of the fan unit 30 in addition to the rotating mechanism 80. The room air blown from the fan unit 30 is deflected left and right by the left and right wind direction plates 36.

As shown in FIG. 3, the fan unit 30 includes an auxiliary blower fan 33 for sucking room air and blowing out the sucked room air. The auxiliary blower fan 33 is disposed inside the fan unit 30. A motor 34 is connected to the auxiliary blower fan 33, and the auxiliary blower fan 33 is rotated by rotating the motor 34. The fan unit 30 is provided with an auxiliary suction port 31 for sucking room air from the outside in the direction of the horizontal axis 41, and an auxiliary air outlet 32 for blowing the room air sucked from the auxiliary suction port 31 into the indoor space is provided in the fan unit 30. Arranged on the front side.

As shown in FIG. 3, an electrical component unit 26 is disposed inside the main unit 20. The electrical component unit 26 includes a control unit 53 that controls the blower fan 27 and the auxiliary blower fan 33, a temperature sensor 51 that detects the temperature of the indoor air sucked from the suction port 21, and a humidity that detects the humidity of the indoor air. A sensor 52 and a storage unit 54 are provided.

Moreover, the control part 53 deflects the blowing direction of the conditioned air which blows off from the blower outlet 22 by controlling the direction of the wind direction board of the 1st wind direction deflection | deviation means (upper and lower wind direction board 29a, 29b) of the main body unit 20. FIG. Further, the second air direction deflecting means (the rotation mechanism 80 and the left and right air direction plates 36) of the fan unit 30 is controlled to deflect the blowing direction of the room air blown out from the auxiliary air outlet 32.

Further, the storage unit 54 stores, as the first temperature, a set temperature (for example, 25 ° C.) set as the indoor temperature at which the user can feel comfortable during the operation in the cooling cycle such as the cooling operation and the dehumidifying operation. ing.

The electrical component unit 26 is attached to the front side of the main body unit 20, and thus is disposed at a position where air sucked from the suction port 21 by the blower fan 27 circulates. For example, as shown in FIG. 4, the electrical component unit 26 is disposed between the suction port 21 and the indoor heat exchanger 25. In addition, the temperature sensor 51 and the humidity sensor 52 provided in the electrical component unit 26 detect the temperature and humidity in the room as the air sucked from the suction port 21 by the blower fan 27 circulates around these sensors. I can do it.

Next, operations of the main unit 20 and the fan unit 30 when the air conditioner 1 is operated in the cooling cycle will be described. During the cooling cycle operation, the indoor heat exchanger 25 shown in FIG. 4 functions as an evaporator that absorbs heat from the air to generate cold air, and the cold air that is conditioned air blown out from the air outlet 22 is the first air direction. By the deflecting means (29a, 29b), it is deflected in the horizontal direction toward the front side of the main unit 20 and blown out. Thereby, cold air can be spread indoors.

When the temperature of the room air detected by the temperature sensor 51 is higher than the first temperature, such as at the start of the cooling cycle operation, the auxiliary air outlet 32 is tilted downward from the horizontal direction by the rotation mechanism 80 of the second air direction deflecting means. The fan unit 30 is rotated until it faces in the direction, and the room air blown out from the auxiliary air outlet 32 is directed in the direction in which the user is present, so that the user can feel coolness without feeling cold due to cold air. Is provided.

When the temperature of the room air detected by the temperature sensor 51 reaches the first temperature by the operation of the cooling cycle, the control unit 53 reduces the air volume of the blower fan 27 in order to prevent the room temperature from falling below the set temperature. Adjust the cooling capacity by lowering it so that users do not feel the discomfort caused by the cold. In addition, when the humidity of the indoor air detected by the humidity sensor 52 reaches the set humidity, the control unit 53 causes the user to feel uncomfortable due to the cold when the heat of the room disappears and the room temperature further decreases. Adjust the cooling capacity by reducing the air flow.

When the air volume of the blower fan 27 decreases, the air volume of the indoor air sucked into the main unit 20 decreases, and the temperature of the conditioned air generated by heat exchange with the refrigerant in the heat exchanger 25 is the first temperature of the indoor air. It will be lower than before reaching. Moreover, the air volume of the conditioned air blown out from the air outlet 22 is also smaller than before the temperature of the room air reaches the first temperature. Even if the conditioned air thus formed is blown out in the horizontal direction from the air outlet 22, since the wind speed is slow, the cool air falls near the indoor unit 10, so that the users near the indoor unit 10 Cold air hits directly and gives discomfort.

For this reason, when the temperature of the room air detected by the temperature sensor 51 reaches the first temperature, the control unit 53 causes the auxiliary air outlet 32 to be directed in the horizontal direction by the rotation mechanism 80 of the second wind direction deflecting means. By rotating the fan unit 30 until the left and right wind direction plates 36 of the second wind direction deflecting means provided at the auxiliary air outlet 32 are directed toward the main unit 20, the room air blown from the auxiliary air blowing fan 33 is The first wind direction deflecting means (upper and lower wind direction plates 29a and 29b) deflect the air so as to blow out toward the conditioned air blown out from the blowing fan 27 deflected. Here, the wind speed of the airflow blown from the auxiliary blower fan 33 is controlled to be higher than the wind speed of the airflow blown from the blower fan 27.

By controlling the wind direction in this way, the flow of conditioned air (cold air) whose wind speed has been slowed by reducing the air volume is separated from the indoor unit 10 by the fast air flow blown from the auxiliary blower fan 33. Therefore, it is possible to prevent the cool air blown from the blower fan 27 from directly hitting the user and maintain the comfort of the user.

FIG. 6 is a flowchart showing the process of the first embodiment of the control unit 53 of the indoor unit 10 during the operation of the cooling cycle according to the present invention. As a condition for starting the processing in FIG. 6, it is assumed that an operation in a cooling cycle such as a cooling operation or a dehumidifying operation is instructed from a remote controller or the like. Note that ST described in the flowchart represents a step, and the subsequent numbers represent step numbers.

As shown in FIG. 6, when the operation in the cooling cycle is instructed, the control unit 53 blows out cold air, which is conditioned air, horizontally by the first air direction deflecting means (upper and lower air direction plates 29a, 29b), The air direction deflecting means (rotating mechanism 80) is controlled so as to blow the room air obliquely downward from the horizontal direction (ST1). The controller 53 determines whether or not the temperature of the room air detected by the temperature sensor 51 is equal to or lower than the first temperature stored in the storage unit 54 (ST2). When the temperature of room air is not below the first temperature (ST2-No), the process returns to ST1.

In ST2, when the temperature of the room air is equal to or lower than the first temperature (ST2-Yes), the controller 53 reduces the air volume of the blower fan 27 (ST3). The control unit 53 controls the second wind direction deflecting means (the rotation mechanism 80 and the left and right wind direction plates 36) so as to blow the room air from the auxiliary blower fan 33 toward the conditioned air blown from the blower fan 27 (ST4). ). The controller 53 determines whether or not the temperature of the room air detected by the temperature sensor 51 is equal to or lower than the first temperature stored in the storage unit 54 (ST5). When the temperature of the room air is not lower than the first temperature (ST5-No), the process returns to ST1.

When the temperature of the room air is equal to or lower than the first temperature in ST5 (ST5-Yes), the control unit 53 determines whether or not the control unit 53 is instructed to stop the operation of the cooling cycle such as the cooling operation or the dehumidifying operation. Is determined (ST6). When the stop of the cooling cycle operation is not instructed (ST6-No), the process returns to ST5. On the other hand, when the stop of the cooling cycle operation is instructed in ST6 (ST6-Yes), the control unit 53 ends the operation of the cooling cycle and ends the process.

The control unit 53 performs the processing shown in FIG. 6 to reduce the air volume of the blower fan 27 on the assumption that the room temperature has reached the set temperature during the operation of the air conditioner 1 in the cooling cycle such as the cooling operation and the dehumidifying operation. The indoor air blown out from the auxiliary blower fan 33 is applied to the conditioned air (cold air) blown out from the blower fan 27, so that the conditioned air (cold air) does not fall and the user is prevented from directly hitting the cold air. Can maintain comfort.

The second embodiment is an example in which the humidity sensor 52 is used in addition to the control by the temperature sensor 51 of the first embodiment. In the storage unit 54 of the second embodiment, the first set temperature (for example, 25 ° C.) set as the indoor temperature at which the user can feel comfortable during the operation by the cooling cycle such as the cooling operation and the dehumidifying operation is the first. The indoor humidity (for example, 50%) that is stored as the temperature and that the user can feel comfortable as the set humidity is stored, and the first temperature as the indoor temperature that does not feel muggy when the humidity falls to the set humidity A temperature higher than a predetermined temperature (for example, 27 ° C. that is 2 ° C. higher than the first temperature) is stored as the second temperature.

In the air conditioner 1 according to the second embodiment, the humidity of the room air detected by the humidity sensor 52 reaches the set humidity during the operation of the cooling cycle, and the temperature of the room air detected by the temperature sensor 51 is higher than the first temperature. When the second temperature is reached, the control unit 53 adjusts the cooling operation capacity by lowering the air volume of the blower fan 27, and the auxiliary air blow by the second wind direction deflecting means (the rotation mechanism 80 and the left and right wind direction plates 36). The room air blown from the fan 33 is deflected so as to blow toward the conditioned air blown from the blower fan 27 deflected by the first wind direction deflecting means (upper and lower wind direction plates 29a and 29b).

By controlling the air direction in this way, even when the air volume of the blower fan 27 is reduced to adjust the cooling performance before the room air temperature reaches the first temperature, the cool air blown out from the blower fan 27 is also reduced. It is possible to prevent the cool air from directly hitting the user by preventing the user from descending near the indoor unit 10.

FIG. 7 is a flowchart illustrating the processing of the second embodiment. The conditions for starting the process of FIG. 7 are the same as the conditions for starting the process of FIG.

As shown in FIG. 7, when the operation in the cooling cycle is instructed, the control unit 53 blows out cool air, which is conditioned air, in the horizontal direction by the first wind direction deflecting unit, and blows indoor air by the second wind direction deflecting unit. Control is performed so as to blow obliquely downward from the horizontal direction (ST11). The controller 53 determines whether or not the humidity of the room air detected by the humidity sensor 52 is equal to or lower than the set humidity stored in the storage unit 54 (ST12). When the humidity of the room air is equal to or lower than the set humidity (ST12-Yes), the control unit 53 determines whether the temperature of the room air detected by the temperature sensor 51 is equal to or lower than the second temperature stored in the storage unit 54. It is determined whether or not (ST14).

In ST14, when the temperature of the room air is equal to or lower than the second temperature (ST14-Yes), the control unit 53 proceeds to ST15. Moreover, when the temperature of room air is not below 2nd temperature (ST14-No), it returns to ST11. On the other hand, if the humidity of the room air is not lower than the set humidity in ST12 (ST12-No), the control unit 53 determines the first temperature stored in the storage unit 54 as the temperature of the room air detected by the temperature sensor 51. It is determined whether or not the following is true (ST13). When the temperature of the room air is equal to or lower than the first temperature (ST13-Yes), the process proceeds to ST15. Moreover, when the temperature of room air is not below 1st temperature (ST13-No), it returns to ST11.

The controller 53 reduces the air volume of the blower fan 27 in ST15. Subsequently, the control unit 53 controls the second wind direction deflecting means (the rotation mechanism 80 and the left and right wind direction plates 36) so as to blow the room air from the auxiliary blower fan 33 toward the conditioned air blown from the blower fan 27. (ST16). Subsequently, the control unit 53 determines whether or not the temperature of the room air detected by the temperature sensor 51 is equal to or lower than the second temperature stored in the storage unit 54 (ST17).

When the temperature of the room air is equal to or lower than the second temperature in ST17 (ST17-Yes), the control unit 53 stores the humidity of the room air detected by the humidity sensor 52 in the storage unit 54. It is determined whether or not the set humidity is below (ST18). When the humidity of the room air is equal to or lower than the set humidity (ST18-Yes), the control unit 53 determines whether or not the stop of the cooling cycle operation such as the cooling operation or the dehumidifying operation is instructed (ST19). When the stop of the cooling cycle operation is not instructed (ST19-No), the process returns to ST17.

On the other hand, when the temperature of the room air is not lower than the second temperature in ST17 (ST17-No), the control unit 53 returns to ST11. If the humidity of the room air is not lower than the set humidity in ST18 (ST18-No), the control unit 53 returns to ST11. Further, when an instruction to stop the operation of the cooling cycle is given in ST19 (ST19-Yes), the control unit 53 ends the operation of the cooling cycle and ends the processing.

The control unit 53 performs the processing shown in FIG. 7 so that the humidity of the room air reaches the set humidity before the temperature of the room air falls below the first temperature, and the temperature of the room air falls below the second temperature. If it has reached, the indoor air blown out from the auxiliary blower fan 33 is applied to the conditioned air (cold air) blown out from the blower fan 27 so that the flow of the conditioned air (cold air) is strengthened so as not to descend, and the user directly hits the cold air. Can be prevented and user comfort can be maintained.
