Description

  The present invention generally relates to an air conditioner, and more particularly to an air conditioner that performs temperature control during sleep.

  Conventionally, there has been known an air conditioner that switches from a normal operation mode to a sleep operation mode as a sleep operation during driving, and allows a comfortable sleep by changing the room temperature in the sleep operation mode. Yes.

For example, Japanese Patent Laid-Open No. 3-225141 (Patent Document 1) proposes an air conditioner control device that performs comfortable temperature control during sleep. The air conditioner control device includes a room temperature setting means for setting a room temperature, an operation determination means for determining a cooling sleep operation time, a time measurement means for measuring an elapsed time from the cooling sleep operation operation, and an operation determination. Control means for detecting a signal from the means and lowering the set temperature by the first temperature by the room temperature setting means and then raising the set temperature by the second temperature after a predetermined time by the time measuring means is provided.
JP-A-3-225141

  However, in the conventional air conditioner, when the outside air temperature decreases during the cooling operation, the temperature of the indoor heat exchanger also decreases. Therefore, the cold air may hit the sleeping person and the sleeping person may feel cold.

  Further, as in the air conditioner described in the above publication, when the set temperature is once lowered and then raised, the operation of the compressor is stopped when the outside air temperature is low such as at night, and only the indoor fan is operated. Therefore, there is a problem that dehumidification cannot be performed. For this reason, the condensed water adhering to an indoor heat exchanger may be discharged | emitted indoors with ventilation. As a result, the indoor relative humidity increases, and the indoor humidity may become uncomfortable during sleep.

  Further, in the conventional air conditioner, during the heating operation, hot air blows on the sleeper, and the sleeper may become difficult to sleep.

  Then, the objective of this invention is providing the air conditioner which can make a more comfortable sleep environment.

  An air conditioner according to the present invention controls a compressor and an indoor fan according to an operation mode selected by a selection unit that selects a predetermined operation mode from a plurality of operation modes including a sleep operation mode. A control unit, an indoor temperature detection unit that detects an indoor temperature, and a blowing temperature detection unit that detects the temperature of air blown into the room are provided. When the sleep mode is selected by the selection unit, the control unit controls the rotation speed of the compressor according to the blown air temperature detected by the blown temperature detection unit.

  In the air conditioner of the present invention, since the rotation speed of the compressor is controlled according to the blown air temperature, the blown air temperature does not become too cold for the sleeper during the cooling operation, and the blowout air is blown during the heating operation. A comfortable sleeping environment can be created without the air temperature becoming hot for the sleeper.

  In the air conditioner of this invention, when the sleep operation mode is selected by the selection unit, the control unit preferably decreases the rotational speed of the indoor fan.

  By doing in this way, since the quantity of the wind sent out indoors can be decreased, a comfortable wind for a sleeper can be sent indoors.

  In the air conditioner of the present invention, the compressor rotation speed is controlled by a predetermined difference between the set indoor temperature set in the sleep operation mode and the detected indoor temperature detected by the indoor temperature detector. Preferably, it is carried out when the temperature difference is within the specified range.

  In this way, when the detected room temperature approaches the set room temperature, the number of revolutions of the compressor is controlled according to the blown air temperature, so that a comfortable sleep environment is created in a state of room temperature preferable for the sleeper. be able to.

  In this case, it is preferable that the rotation speed of the compressor is controlled according to the difference between the set room temperature and the detected room temperature.

  In the air conditioner according to the present invention, when the sleep operation mode is selected by the selection unit during the cooling operation, the control unit rotates the compressor when the difference between the detected room temperature and the blown air temperature is relatively large. It is preferable to control so that the number of rotations of the compressor is increased when the number is decreased and the difference between the detected room temperature and the blown air temperature is relatively small.

  By doing in this way, the blowing air temperature can be controlled to a comfortable temperature.

  Further, in the air conditioner of the present invention, when the sleep operation mode is selected by the selection unit during the cooling operation, the control unit sets the upper limit value in a range in which the difference between the detected room temperature and the blown air temperature is determined in advance. If the difference between the detected room temperature and the blown air temperature is relatively smaller than the lower limit value of the predetermined range, the compressor speed is decreased. When the difference between the detected room temperature and the blown air temperature is within a predetermined range, it is preferable to perform control so as to maintain the rotational speed of the compressor.

  By doing in this way, the blowing air temperature can be controlled to a comfortable temperature range.

  In the air conditioner of the present invention, when the sleep operation mode is selected by the selection unit during the cooling operation, the blown air temperature is a first dew point corresponding to a predetermined first humidity at the detected indoor temperature. The control unit may control the rotational speed of the compressor so that the temperature is within a range of a second dew point temperature corresponding to a predetermined second humidity higher than the first humidity. preferable.

  By doing in this way, at the time of air_conditionaing | cooling operation, the blowing air temperature can be controlled to the range of the dew point temperature corresponding to a predetermined humidity range. For this reason, it is possible to control so that the indoor humidity does not decrease below a certain value during sleep driving and does not become too high.

  In the air conditioner according to the present invention, when the sleep operation mode is selected by the selection unit during the heating operation, the blown air temperature is higher than the human body temperature and the first predetermined temperature and the first temperature. It is preferable that the control unit controls the rotation speed of the compressor so that the temperature is within a predetermined second temperature range that is higher than the predetermined temperature.

  By doing in this way, at the time of heating operation, it is possible to control the blown air temperature so as not to rise above a certain value higher than the human body temperature. For this reason, it is possible to control so that the indoor temperature does not become too high during sleep driving.

  In the air conditioner of the present invention, it is preferable that the blowout temperature detector detects at least one of the temperature of the air at the blowout port and the temperature of the air in the indoor heat exchanger.

  As described above, according to the present invention, since the rotation speed of the compressor is controlled according to the temperature of the blown air, a more comfortable sleep environment can be created.

  An embodiment of the present invention will be described below with reference to the drawings.

  FIG. 1 is a diagram showing a refrigeration cycle of an air conditioner as one embodiment of the present invention.

  As shown in FIG. 1, the air conditioner 1 includes an indoor unit 10 and an outdoor unit 20. The indoor unit 10 includes an indoor heat exchanger 11, an indoor fan 12, and a control unit 17 as an indoor control device. The outdoor unit 20 includes a compressor 21, a four-way valve 24, an outdoor heat exchanger 25, an outdoor fan 26, an expansion valve 28, and a control unit 29 as an outdoor control device.

  The indoor fan 12 is for passing indoor air through the indoor heat exchanger 11 and is driven by an indoor fan motor 13. The compressor 21 is driven by a compressor motor 22, and an accumulator 23 is connected to the suction side. The outdoor fan 26 is for passing outdoor air through the outdoor heat exchanger 25 and is driven by an outdoor fan motor 27.

  Two valves are provided in the connection path between the indoor unit 10 and the outdoor unit 20, and each component of the indoor unit 10 and the outdoor unit 20 is sequentially connected by a refrigerant pipe to form a known refrigeration cycle.

  During the cooling operation, the refrigerant is stored in the compressor 21, the four-way valve 24, the outdoor heat exchanger 25, the expansion valve 28, the indoor heat exchanger 11, the four-way valve 24, the accumulator 23, and the compressor 21 as indicated by solid arrows. Cycles in order. In this case, the outdoor heat exchanger 25 functions as a condenser, and the indoor heat exchanger 11 functions as an evaporator.

  During the heating operation, as indicated by the broken-line arrows, the refrigerant passes through the compressor 21, the four-way valve 24, the indoor heat exchanger 11, the expansion valve 28, the outdoor heat exchanger 25, the four-way valve 24, the accumulator 23, and the compressor 21. Cycles in order. In this case, the indoor heat exchanger 11 functions as a condenser, and the outdoor heat exchanger 25 functions as an evaporator.

  The indoor unit 10 includes an indoor temperature detector 14 that detects the temperature of the room and a blowout temperature detector 15 that detects the temperature of the air blown into the room. And a heat exchanger temperature detector 16 that detects the temperature of air in the indoor heat exchanger 11. The control unit 17 detects the set indoor temperature set according to the selected operation mode, the detected indoor temperature detected by the indoor temperature detection unit 14, and the outlet temperature detection unit 15 or the heat exchanger temperature detection unit 16. The rotational speed of the indoor fan 12, that is, the rotational speed of the indoor fan motor 13 is controlled according to the blown air temperature, and control information is transmitted to the control unit 29. In accordance with the control information received from the control unit 17, the control unit 29 rotates the compressor 21, that is, the compressor motor 22, and the outdoor fan 26, that is, the outdoor fan motor 27. Control number and.

  FIG. 2 is a flowchart showing a processing procedure in the sleep operation mode of the microcomputer constituting the control unit 17 or the control unit 29 shown in FIG. 1 during the cooling operation. FIG. 3 is a diagram showing a configuration of a remote controller of the air conditioner as one embodiment of the present invention.

  With reference to FIG. 1 to FIG. 3, a processing procedure when the sleep operation mode is selected during the cooling operation will be described.

  As shown in FIG. 3, the remote controller 30 is a selection unit that can select a predetermined operation mode from a plurality of operation modes including at least a “good night” operation mode as a sleep operation mode.

  First, in step S1, the “good night” button 31 shown in FIG. 3 is pressed during the cooling operation. As a result, when “sleeping” driving as the sleep driving mode is selected by the remote controller 30 as the selection unit, the “sleeping” driving mode is transmitted from the remote controller 30 to the control unit 17 of the indoor unit 10.

  Then, in step S <b> 2, the control unit 17 transmits a control signal for reducing the rotational speed to the indoor fan 12. At this time, specifically, by reducing the number of rotations of the indoor fan 12, the amount of air blown into the room is changed to “slight wind”. During cooling operation, the wind direction should be diagonally upward.

  As described above, when the “sleep” operation mode is selected during the cooling operation, the control unit 17 can reduce the amount of air sent into the room by reducing the rotational speed of the indoor fan 12. A comfortable wind for sleepers can be sent indoors. Further, since the wind direction is obliquely upward during the cooling operation, the cold air is not directly applied to the sleeping person, so that the sleeping person can sleep without feeling cold.

  Next, the control unit 17 detects the detected indoor temperature Tr detected by the indoor temperature detection unit 14 and the blowout air temperature detected by the blowout outlet temperature detection unit 15 or the heat exchanger temperature detection unit 16 as the blowout temperature detection unit. In accordance with Td, a control signal is transmitted to the control unit 29 so as to control the rotation speed of the compressor 21. In response to this control signal, the control unit 29 performs integral control of the rotational speed of the compressor 21.

  As described above, since the rotation speed of the compressor 21 is controlled according to the detected indoor temperature Tr and the blown air temperature Td, the blown air temperature Td does not become too cold for the sleeper during the cooling operation. A sleep environment can be created.

  Specifically, in step S3, first, a difference (Tr−Ts) between the set room temperature Ts set in the “sleep” operation mode and the detected room temperature Tr detected by the room temperature detection unit 14 is determined in advance. It is determined whether or not the temperature is within a predetermined temperature difference Δt. If the difference between the set room temperature Ts and the detected room temperature Tr (Tr−Ts) is within the range of the temperature difference Δt, the rotational speed of the compressor 21 is controlled. For example, if (Tr−Ts) is Δt = 1.3 ° C. or less (YES), the rotational speed of the compressor 21 is controlled, and if it exceeds Δt (NO), the rotational speed of the compressor 21 is controlled. Is not done. The set room temperature Ts is increased stepwise after the time determined by the fuzzy calculation, for example, after 60 minutes after the “good night” operation mode is set.

  As described above, when the detected room temperature Tr approaches the set room temperature Ts, the rotation speed of the compressor 21 is controlled according to the blown air temperature Td. Can be made.

  Then, when the difference between the detected room temperature Tr and the blown air temperature Td is relatively large, the control unit 17 decreases the rotational speed of the compressor 21, and the difference between the detected room temperature Tr and the blown air temperature Td is relatively high. When it is small, a control signal for controlling the rotation speed of the compressor 21 to increase is transmitted to the control unit 29. By doing in this way, the blowing air temperature Td can be controlled to a comfortable temperature.

  Preferably, when the difference between the detected room temperature Tr and the blown air temperature Td is relatively larger than the upper limit value t2 of the predetermined range, the control unit 17 decreases the rotation speed of the compressor 21 and detects the detected room temperature. When the difference between the temperature Tr and the blown air temperature Td is relatively smaller than the lower limit value t1 of a predetermined range, the rotational speed of the compressor 21 is increased, and the difference between the detected room temperature Tr and the blown air temperature Td. Is within a predetermined range (t1 ≦ (Tr−Td) ≦ t2), a control signal for controlling to maintain the rotation speed of the compressor 21 is transmitted to the control unit 29. By doing in this way, the blowing air temperature Td can be controlled to a comfortable temperature range.

  Specifically, when the difference (Tr−Td) between the detected room temperature Tr and the blown air temperature Td is larger than t2 (YES) in step S4, the rotational speed of the compressor 21 is decreased in step S5. Let

  In step S4, the difference between the detected room temperature Tr and the blown air temperature Td (Tr−Td) is smaller than t2 (NO), and in step S6, the difference between the detected room temperature Tr and the blown air temperature and Td. When (Tr−Td) is smaller than t1 (YES), the rotational speed of the compressor 21 is increased in step S7.

  In step S4, the difference between the detected room temperature Tr and the blown air temperature Td (Tr−Td) is smaller than t2 (NO), and in step S6, the difference between the detected room temperature Tr and the blown air temperature and Td. When (Tr−Td) is larger than t1 (NO), the rotational speed of the compressor 21 is fixed, that is, maintained in step S8.

  In the control of the compressor 21 described above, when the “good night” operation mode is selected during the cooling operation, the blown air temperature Td corresponds to the first predetermined humidity at the detected indoor temperature Tr. The control unit 17 controls the rotation speed of the compressor 21 so that the temperature is within the range of the dew point temperature and the second dew point temperature corresponding to the predetermined second humidity higher than the first humidity. The control signal to be transmitted is preferably transmitted to the control unit 29. By doing in this way, at the time of air_conditionaing | cooling operation, the blowing air temperature Td can be controlled to the range of the dew point temperature corresponding to a predetermined humidity range. For this reason, it can control so that indoor humidity may not become high too much at the time of sleep driving. Moreover, it can control so that indoor humidity may not fall below a fixed value at the time of sleep driving. Furthermore, the temperature of the indoor heat exchanger 11 is not increased until the evaporation temperature at which the humidity becomes unpleasant.

  For example, if the first humidity is 45% and the second humidity is 65%, the first dew point temperature corresponding to the first humidity is (Tr-13) ° C., and the second humidity corresponding to the second humidity. The dew point temperature is approximated to (Tr-7) ° C. Therefore, the rotation speed of the compressor 21 is controlled so that (Tr-13) ≦ Td ≦ (Tr-7). Thereby, the rotation speed of the compressor 21 is controlled so that 7 ≦ (Tr−Td) ≦ 13. That is, t1 = 7 ° C. and t2 = 13 ° C. are set during the cooling operation.

  In this case, the rotation speed of the compressor 21 is controlled according to the value of the difference (Tr−Ts) between the set room temperature Ts and the detected room temperature Tr.

  For example, in the cooling operation, when the difference between the set room temperature Ts and the detected room temperature Tr is Δt = 1.3 ° C. or less and larger than 0.7 ° C., t1 = 11 ° C. and t2 = 13 ° C. The above compressor is controlled. That is, when the difference between the detected room temperature Tr and the blown air temperature Td is greater than 13 ° C., the control unit 17 decreases the rotational speed of the compressor 21 and the difference between the detected room temperature Tr and the blown air temperature Td is increased. When the temperature is lower than 11 ° C., the number of revolutions of the compressor 21 is increased, and the difference between the detected room temperature Tr, the blown air temperature, and Td is within a predetermined range (11 ° C. <(Tr−Td) ≦ 13 ° C.). At this time, a control signal for controlling the rotation speed of the compressor 21 to be maintained is transmitted to the control unit 29.

  Further, when the difference between the set room temperature Ts and the detected room temperature Tr is Δt = 0.7 ° C. or less and greater than 0 ° C., t1 = 9 ° C. and t2 = 12 ° C. I do. That is, when the difference between the detected room temperature Tr and the blown air temperature Td is greater than 12 ° C., the control unit 17 decreases the rotational speed of the compressor 21 and the difference between the detected room temperature Tr and the blown air temperature Td is increased. When the temperature is lower than 9 ° C., the rotational speed of the compressor 21 is increased, and the difference between the detected room temperature Tr, the blown air temperature, and Td is within a predetermined range (9 ° C. <(Tr−Td) ≦ 12 ° C.). At this time, a control signal for controlling the rotation speed of the compressor 21 to be maintained is transmitted to the control unit 29.

  Further, when the difference between the set room temperature Ts and the detected room temperature Tr is equal to or less than Δt = 0 ° C. and greater than −0.7 ° C., t1 = 7 ° C. and t2 = 8 ° C. are set. Take control. That is, when the difference between the detected room temperature Tr and the blown air temperature Td is larger than 8 ° C., the control unit 17 decreases the rotational speed of the compressor 21 and the difference between the detected room temperature Tr and the blown air temperature Td is increased. When the temperature is lower than 7 ° C., the rotational speed of the compressor 21 is increased, and the difference between the detected room temperature Tr, the blown air temperature, and Td is within a predetermined range (7 ° C. <(Tr−Td) ≦ 8 ° C.). At this time, a control signal for controlling the rotation speed of the compressor 21 to be maintained is transmitted to the control unit 29.

  Furthermore, when the difference between the set room temperature Ts and the detected room temperature Tr is Δt = −0.7 ° C. or less, the compressor is controlled as t1 = 7 ° C. and t2 = 8 ° C. That is, when the difference between the detected room temperature Tr and the blown air temperature Td is larger than 8 ° C., the control unit 17 decreases the rotational speed of the compressor 21 and the difference between the detected room temperature Tr and the blown air temperature Td is increased. When the temperature is lower than 7 ° C., the rotational speed of the compressor 21 is increased, and the difference between the detected room temperature Tr, the blown air temperature, and Td is within a predetermined range (7 ° C. <(Tr−Td) ≦ 8 ° C.). At this time, a control signal for controlling the rotation speed of the compressor 21 to be maintained is transmitted to the control unit 29.

  Note that when the “sleep” operation mode is selected during the heating operation (step S1), the amount of air blown into the room is changed to “slight wind” (step S2), and the wind direction is set to be substantially downward.

  During the heating operation, in step S3, a difference (Ts−Tr) between the set room temperature Ts set in the “sleep” operation mode and the detected room temperature Tr detected by the room temperature detection unit 14 is determined in advance. It is determined whether the temperature difference is within the range of Δt. Here, the set indoor temperature Ts is lowered stepwise after the time determined by the fuzzy calculation, for example, after 60 minutes, after the “good night” operation mode is set.

  As described above, when the detected room temperature Tr approaches the set room temperature Ts, the rotation speed of the compressor 21 is controlled according to the blown air temperature Td. Can be made.

  Further, during the heating operation, in step S4, instead of the difference between the detected room temperature Tr and the blown air temperature Td (Tr-Td), the blown air temperature Td is compared with t2, and in step S6, the detected room temperature is detected. Instead of the difference (Tr−Td) between the temperature Tr and the blown air temperature Td, the blown air temperature Td is compared with t1. By doing in this way, the blowing air temperature can be controlled to a comfortable temperature or a comfortable temperature range.

  In this case, the blown air temperature Td is set to a temperature within a range between a predetermined first temperature t1 higher than the human body temperature and a predetermined second temperature t2 higher than the first temperature. In addition, the control unit 17 preferably transmits a control signal for controlling the rotation speed of the compressor 21 to the control unit 29. For example, t1 = 34 ° C. and t2 = 39 ° C. are set during the heating operation. By doing in this way, at the time of heating operation, it is possible to control the blown air temperature so as not to rise above a certain value higher than the human body temperature. For this reason, it is possible to control so that the indoor temperature does not become too high during sleep driving. Further, the temperature of the indoor heat exchanger 11 is not increased until the temperature of the blown air becomes a condensing temperature that makes it difficult to sleep at high temperatures.

  Thus, since the rotation speed of the compressor 21 is controlled according to the blown air temperature Td, the blown air temperature Tr does not become a hot temperature for the sleeper during the heating operation, and a comfortable sleep environment can be created. .

  When the “good night” operation mode is selected during the heating operation, the control unit 17 can reduce the amount of air sent into the room by reducing the number of rotations of the indoor fan 12, so that the sleeping person can A comfortable wind can be sent indoors. In addition, since the wind direction is almost directly downward during the heating operation, the warm air is not directly applied to the sleeping person, so that the sleeping person can sleep without becoming uncomfortable with the high temperature wind.

  In the above embodiment, the values of t1 and t2 are stored in the nonvolatile memory (EEPROM) in the control unit 17 and can be changed as appropriate.

  In the above embodiment, the control unit 17 rotates the compressor 21 according to the detected indoor temperature Tr and the blown air temperature Td during the cooling operation or according to the blown air temperature Td during the heating operation. Although the control signal for controlling the number is transmitted to the control unit 29, the control unit 17 may transmit the control signal for controlling the rotational speed of the outdoor fan 26 to the control unit 29, and the control unit 17 compresses the control signal. A control signal for controlling the rotational speed of the machine 21 and the rotational speed of the outdoor fan 26 may be transmitted to the control unit 29. Even in this case, the above-described effects of the present invention can be achieved.

  The embodiment disclosed above should be considered as illustrative in all points and not restrictive. The scope of the present invention is shown not by the above embodiments but by the scope of claims, and includes all modifications and variations within the meaning and scope equivalent to the scope of claims.
