Description

  The present invention relates to an air conditioner.

  Conventionally, an air conditioner has an operation mode called a timer mode in which operation is automatically started or stopped at a time reserved by a user. Such an air conditioner is disclosed in Patent Document 1.

  The air conditioner described in Patent Document 1 restarts the timer operation when a key other than a specific key on the remote controller is pressed after the operation is stopped by the timer operation function. That is, after the operation is stopped in the off timer mode, the off timer operation can be resumed with the simplest possible operation. As a result, even if the user falls asleep during sleep and wakes up, the operation of the air conditioner can be easily resumed.

  However, the driving sound of the louver in a quiet bedroom before the start or after the operation of the air conditioner may be annoying to the user, and this is not taken into consideration in the conventional air conditioner. There is a problem that a sleeping user may wake up due to the driving sound of such a louver and a suitable sleep may not be obtained.

  This invention is made in view of said point, and provides the air conditioner which can suppress generation | occurrence | production of the drive sound of a louver when an air conditioner starts an operation | movement in a timer mode, or stops. For the purpose.

  In order to solve the above problems, the present invention provides a blower that circulates room air, an indoor heat exchanger that performs heat exchange between the air that is circulated by the blower, and a louver that can change the air blowing direction. An air conditioner capable of operating in an on-timer mode that automatically starts operation at a reserved time, and when the on-timer mode is set during the air-conditioned operation, the air conditioning The louver is displaced to a preset designated position when the operation is stopped.

  According to this configuration, the air conditioner does not drive the louver when the operation starts in the on timer mode. Therefore, no louver driving sound is generated at that time.

  The “designated position” of the louver described here is an arbitrary position (posture) set in advance at the start of operation in the on-timer mode. For example, the louver is designated corresponding to the operation mode such as cooling operation or heating operation. can do.

  Moreover, in order to solve said subject, this invention is the louver which can change the blowing direction of air, the indoor heat exchanger which performs heat exchange between the air blower which circulates indoor air, the air which the said air fan circulates An air conditioner that can be operated in the off timer mode that automatically stops operation at the reserved time, and when the off timer mode is set, the operation of the off timer mode is performed. The operation is stopped without returning the louver to the initial position when stopping.

  According to this configuration, the air conditioner does not drive the louvers when the operation is stopped in the off timer mode. Therefore, no louver driving sound is generated at that time.

  The “initial position” of the louver mentioned here means the position (posture) when the air conditioner is normally stopped. For example, when the louver also serves as an exterior member that closes and closes the air outlet of the air conditioner, the “initial position” of the louver is a position (closed posture) where the air outlet is closed.

  Moreover, in order to solve said subject, this invention is the louver which can change the blowing direction of air, the indoor heat exchanger which performs heat exchange between the air blower which circulates indoor air, the air which the said air fan circulates An air conditioner capable of operating in an on-timer mode that automatically starts operation at a reserved time and a shut-off timer mode that automatically stops operation at a reserved time. When the on-timer mode is set, when the air-conditioning operation is stopped, the louver is displaced to a preset designated position, and when the off-timer mode is set, when the operation is stopped in the off-timer mode. The operation is stopped without returning the louver to the initial position.

  According to this configuration, the air conditioner does not drive the louvers when the operation is started or stopped in the timer mode. Therefore, no louver driving sound is generated at that time.

  Moreover, in order to solve said subject, this invention is the louver which can change the blowing direction of air, the indoor heat exchanger which performs heat exchange between the air blower which circulates indoor air, the air which the said air fan circulates An air conditioner capable of operating in an on-timer mode that automatically starts operation at a reserved time, and when the on-timer mode is set while the air-conditioning operation is stopped, When setting, the louver is displaced to a predetermined position set in advance, or when the on-timer mode is set while the air-conditioning operation is stopped, after a predetermined time elapses and before starting the operation in the on-timer mode. Further, the louver is displaced to a preset designated position.

  According to this configuration, when the operation is stopped, the louver is set so as not to be driven from the initial position to the designated position at the start of the operation in the on timer mode. Therefore, generation of driving sound of the louver can be suppressed. Further, by displacing the louver after a predetermined time has elapsed, it is possible to prevent the user from misunderstanding that the operation was instructed by the louver being displaced immediately after setting the on-timer mode during operation stop.

  Note that the “predetermined time” described here is an arbitrary time set in advance regarding the timing for displacing the louver, and is the time until the user goes to bed after setting the on-timer mode, such as 10 minutes, 15 minutes, etc. It doesn't matter as time. In the embodiment described later, this “predetermined time” is set to “10 minutes”, but it is not limited to such a time. In the following configuration, the “predetermined time” may be used in the same way, but these “predetermined times” do not mean the same time. In addition, the “predetermined time” may be set to an arbitrary value using an operating device described later.

  In the air conditioner having the above-described configuration, when the cut-off timer mode is set, the louver is returned to the initial position after a predetermined time has elapsed.

  According to this configuration, for example, after the user wakes up from sleep, the air conditioner returns the louver to the initial position. Therefore, the generation of the driving sound of the louver during sleep is prevented, and the appearance of the air conditioner after the user wakes up does not feel uncomfortable.

  The “predetermined time” described here is an arbitrary time set in advance with respect to the timing for displacing the louver, and is a time until the user wakes up after setting the off timer mode, for example, 6 hours, 7 hours, etc. It doesn't matter as time. In the embodiment described later, this “predetermined time” is set to “7 hours”, but is not limited to such a time. In addition, the “predetermined time” may be set to an arbitrary value using an operating device described later.

  Further, in the air conditioner having the above-described configuration, an operation device for operating the air conditioner is provided, and when the operation is stopped without returning the louver to the initial position when the operation is stopped in the turn-off timer mode, The louver is returned to the initial position by receiving an instruction to return the louver to the initial position.

  According to this configuration, the louver is returned to the initial position when the user is surely waking up. Therefore, the generation of the driving sound of the louver during sleep is surely prevented, and the appearance of the air conditioner after the user wakes up does not feel uncomfortable.

  Further, in the air conditioner having the above configuration, when the operation is stopped without returning the louver to the initial position when the operation is stopped in the cut-off timer mode, the operation unit that can operate the air conditioner and displays the operation information is provided. The position of the louver at the time of the stop is displayed on the operation device.

  According to this configuration, the user may notice that the louver has not returned to the initial position by looking at the operating device when waking up. Therefore, the generation of the driving sound of the louver during sleep is surely prevented, and the appearance of the air conditioner after the user wakes up does not feel uncomfortable.

  Further, in the air conditioner having the above configuration, when the turn-off timer mode and the on-timer mode are set during operation, the louver is operated from the stop of the operation by the turn-off timer mode to the start of operation by the on-timer mode. It is characterized by making it impossible to displace.

  According to this configuration, the louver is not driven until the air conditioner is stopped in the timer mode and then restarted. Therefore, the generation of the driving sound of the louver during that time is prevented.

  According to the structure of this invention, generation | occurrence | production of the drive sound of a louver when an air conditioner starts an operation | movement with a timer mode or when it stops can be suppressed.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  Initially, the structure and operation | movement are demonstrated about the air conditioner of embodiment of this invention using FIGS. 1 is an external perspective view of an indoor unit of an air conditioner, FIG. 2 is a schematic cross-sectional view showing the configuration of the indoor unit, FIG. 3 is a front view of a remote control of the air conditioner, and FIG. FIG. 5 is an explanatory view showing the movement of the louver during the cooling operation of the air conditioner, and FIG. 6 is an explanatory view showing the movement of the louver during the heating operation of the air conditioner. Note that the right side of the indoor unit in FIG. 2 is the side facing the room and is referred to as the front of the indoor unit.

  An indoor unit 1 shown in FIG. 1 is configured as a separate type air conditioner A together with an outdoor unit (not shown). The indoor unit 1 has a horizontally long shape extending in the horizontal direction, and houses the blower 11 and the indoor heat exchanger 12 shown in FIG. 2 inside a synthetic resin casing 10.

  The blower 11 includes a cross low fan (not shown) that extends horizontally in the horizontal direction along the shape of the housing 10 and an electric motor (not shown) that rotates the fan.

  The indoor heat exchanger 12 extends in the horizontal direction like the cross low fan, and is configured by combining three pieces. The three indoor heat exchangers 12 are arranged so as to cover the upper side and the front side of the cross low fan of the blower 11. Refrigerant is fed into the indoor heat exchanger 12 from a compressor (not shown) housed in the outdoor unit.

  The blower 11 circulates room air. The indoor heat exchanger 12 exchanges heat with the air circulated by the blower 11.

  As shown in FIG. 2, a suction port 13 is formed in a portion from the upper front surface of the housing 10 to the top surface. The suction port 13 is composed of a large number of slits. A blower outlet 14 having a horizontally long rectangle when viewed from the front is formed in the lower front portion of the housing 10. A ventilation path 15 through which the air sent from the blower 11 passes is formed between the blower 11 and the blower outlet 14. When the blower 11 is driven, the room air sucked into the housing 10 from the suction port 13 passes through the indoor heat exchanger 12 and is blown out from the air outlet 14 toward the room through the ventilation path 15.

  A filter 16 is disposed immediately inside the suction port 13. The filter 16 covers the upper portion of the indoor heat exchanger 12 and collects dust contained in the indoor air sucked into the housing 10 through the suction port 13. The filter 16 can be reused after being taken out and cleaned by opening the open / close panel 17 provided on the front surface of the indoor unit 1.

  A louver 18 is disposed at the air outlet 14. The louver 18 also serves as an exterior member that closes and closes the air outlet 14 when the air conditioner A is stopped. Like the air outlet 14, the louver 18 has a horizontally long rectangle as viewed from the front. As depicted by a two-dot chain line and an arrow in FIG. 2, the louver 18 is supported by the housing 10 with the upper side extending in the horizontal direction being the center of rotation and being able to swing the lower side, and passed through the indoor heat exchanger 12. The air blowing direction can be changed. The louver 18 adjusts the upward and downward blowing directions of the air, but the indoor unit 1 also includes a louver (not shown) that adjusts the right and left blowing directions of the air. The louver 18 is an electric type, and the direction can be adjusted by a remote controller to be described later.

  An ion generator 19 is disposed just inside the air outlet 14 of the ventilation path 15. The ion generator 19 is packaged in which an electrode and other electronic components used for discharge for discharging ions are accommodated in a housing. The ion generator 19 is detachably stored in a storage unit (not shown) formed adjacent to the ventilation path 15. The ion generator 19 has a plurality of electrodes facing the ventilation path 15 and discharges the air flowing through the ventilation path 15 so as to include ions generated by discharge at the electrodes.

A voltage having an AC waveform or an impulse waveform is applied to the positive discharge electrode and the negative discharge electrode of the ion generator 19. A positive voltage is applied to the positive discharge electrode, and hydrogen ions generated by corona discharge combine with moisture in the air to generate positive ions mainly composed of H ⁺ (H ₂ O) m. A negative voltage is applied to the negative discharge electrode, and oxygen ions generated by corona discharge combine with moisture in the air to generate negative ions mainly composed of O ₂ ⁻ (H ₂ O) n. Here, m and n are arbitrary natural numbers. H ⁺ (H ₂ O) m and O ₂ ⁻ (H ₂ O) n aggregate on the surface of airborne bacteria and odorous components and surround them.

Then, as shown in the formulas (1) to (3), the active species [.OH] (hydroxyl radical) and H ₂ O ₂ (hydrogen peroxide) are aggregated and formed on the surface of the microorganism or the like by collision. Destroy airborne bacteria and odorous components. Here, m ′ and n ′ are arbitrary natural numbers. Therefore, the ion generator 19 discharges the air flowing through the ventilation path 15 so as to include positive ions and negative ions generated by the discharge at the positive discharge electrode and the negative discharge electrode, for example, indoor sterilization or Deodorization can be performed.

H ⁺ (H ₂ O) m + O ₂ ⁻ (H ₂ O) n → OH + 1 / 2O ₂ + (m + n) H ₂ O (1)
_{^{H + (H 2 O) m}} + H + (H 2 O) m '+ O 2 - (H 2 O) n + O 2 - (H 2 O) n'
→ 2 OH + O ₂ + (m + m ′ + n + n ′) H ₂ O (2)
_{^{H + (H 2 O) m}} + H + (H 2 O) m '+ O 2 - (H 2 O) n + O 2 - (H 2 O) n'
→ H ₂ O ₂ + O ₂ + (m + m ′ + n + n ′) H ₂ O (3)

  In the present embodiment, positive ions and negative ions are generated by the ion generator 19, but only negative ions may be generated.

  In the present invention, the ion includes charged fine particle water. At this time, the ion generator 19 is composed of an electrostatic atomizer, and charged fine particle water containing a radical component is generated by the electrostatic atomizer. That is, condensation water is generated on the surface of the discharge electrode by cooling the discharge electrode provided in the electrostatic atomizer by the Peltier element. Next, when a negative high voltage is applied to the discharge electrode, charged fine particle water is generated from the dew condensation water. Further, negative ions released into the air together with the charged fine particle water are also generated from the discharge electrode.

  The indoor unit 1 houses a control unit 20 in the housing 10 for operation control of the entire air conditioner A including the outdoor unit. The control unit 20 includes a calculation unit and a storage unit (not shown), and controls components such as the blower 11 and the louver 18 and a compressor housed in the outdoor unit based on programs and data stored and input in the storage unit. To realize a series of air conditioning operations. Moreover, the indoor unit 1 is provided with the time measuring part 21 for measuring time, and can grasp | ascertain various time.

  In addition, the air conditioner A includes a remote controller 30 that is an operating device for remote operation illustrated in FIGS. 3 and 4. The remote controller 30 can transmit an operation mode setting, an operation command, and the like to the control unit 20 of the indoor unit 1 using infrared rays or the like to instruct and operate, or display operation information.

  The remote controller 30 has a vertically long casing 31, which includes a display unit 32 on the upper side in FIGS. 3 and 4 and an operation unit 33 on the lower side. The display unit 32 is provided with a display panel composed of a liquid crystal panel or the like.

  The operation unit 33 includes a lid 34. The lid portion 34 is supported by the housing 31 so as to be openable and closable via a hinge portion 35 provided at the lower end in FIGS. 3 and 4. Various operation buttons and indicator lamps are distributed and arranged on the surface of the operation unit 33 and the portion covered by the lid unit 34.

  On the portion of the operation unit 33 that is covered by the lid portion 34, operation buttons related to changing the position of the louver, such as an “up / down wind direction” button 36 and a “left / right wind direction” button 37, are arranged.

  For example, when the up / down air direction is set to automatic, the louver 18 is displaced in the diagonally downward direction, the horizontal direction, and the diagonally upward direction in order from the top shown in FIG. For example, when the up / down wind direction is set to automatic, the louver 18 is displaced in the diagonally backward direction, diagonally downward direction, and downward direction in order from the top shown in FIG. 6 in the heating operation.

  Further, operation buttons related to driving in the timer mode such as an “ON timer” button 38, a “OFF timer” button 39, and a “RESERVE” button 40 are also arranged on the portion covered by the lid portion 34 of the operation unit 33. By operating the “on timer” button 38, the “off timer” button 39, and the “reservation” button 40, the user automatically starts operation at the reserved time, and automatically stops at the reserved time. You can set the operation in the off timer mode.

  And this air conditioner A is suppressing generation | occurrence | production of the drive sound of a louver when the driving | operation is started in the timer mode, or when it stops.

  For example, regarding the on timer mode, when the on timer mode is set during the air conditioning operation such as the cooling operation, the heating operation, and the air blowing operation, when the operation is stopped (for example, the user operates the remote controller 30 to operate the air conditioning operation). The louver 18 is displaced to a preset designated position. The designated position of the louver 18 corresponds to, for example, an obliquely downward direction (upper part in FIG. 5) in the cooling operation, and an obliquely backward direction (upper part in FIG. 6) in the heating operation.

  Further, for example, when the on timer mode is set while the air conditioning operation such as the cooling operation, the heating operation, or the air blowing operation is stopped, the louver 18 is displaced to a designated position at the time of setting. Also, for example, when the on-timer mode is set while the air-conditioning operation such as the cooling operation, the heating operation, or the air-blowing operation is stopped, the louver 18 is designated after a predetermined time has elapsed and before the operation in the on-timer mode is started. The position is displaced (referred to as delay setting in the description of the operation flow described later). The predetermined time used here is an arbitrary time set in advance with respect to the timing for displacing the louver 18, and is the time until the user goes to bed after setting the on-timer mode, for example, 10 minutes. The predetermined time may be automatically set by the air conditioner A or may be arbitrarily set manually by the user.

  Further, for example, when the cut timer mode is set, the operation is stopped without returning the louver 18 to the initial position when the operation is stopped in the cut timer mode. The initial position of the louver 18 is a position when the air conditioner A is normally stopped, that is, a position (closed posture) where the air outlet 14 is closed and closed.

  Here, when the off timer mode is set during the air conditioning operation such as the cooling operation, the heating operation, and the air blowing operation, the louver 18 is not returned to the initial position when the operation is stopped in the off timer mode. In addition, when the timer mode is set while the air conditioning operation such as the cooling operation, the heating operation, or the air blowing operation is stopped, the air conditioning operation is started next, and the louver 18 is moved to the initial position when the operation is stopped by the timer operation mode. Do not return until.

  At this time, since the louver 18 is left without returning to the initial position, the user can return the louver 18 to the initial position by using the remote controller 30. For example, it is possible to return to the initial position by pressing the “stop” button 41 of the remote controller 30 or by pressing the “vertical wind direction” button 36. For this reason, when the operation is stopped without returning the louver 18 to the initial position when the operation is stopped in the off timer mode, the position of the louver 18 at the time of the stop is displayed on the display unit 32 of the remote controller 30. Further, the display may be blinked to make it easier for the user to notice.

  Further, for example, when the cut-off timer mode is set, the louver 18 is returned to the initial position after elapse of a predetermined time set in advance (referred to as delay setting in the description of the operation flow described later). The predetermined time used here is an arbitrary time set in advance with respect to the timing at which the louver 18 is displaced, and is set to, for example, 7 hours after the setting of the off timer mode until the user wakes up. The predetermined time may be automatically set by the air conditioner A or may be arbitrarily set manually by the user. Further, it may be used in combination with enabling the user to return the louver 18 to the initial position using the remote controller 30.

  Next, the operation flow of the air conditioner A in the on timer mode and the off timer mode will be described along the flow shown in FIGS. FIG. 7 is a flowchart showing an operation flow of the air conditioner A in the on timer mode, and FIG. 8 is a flowchart showing an operation flow of the air conditioner A in the off timer mode.

  When the on-timer mode is set using the remote controller 30 in the air conditioner A (start in FIG. 7), the control unit 20 is currently operating (air conditioning operations such as cooling operation, heating operation, and air blowing operation). (Step # 101 in FIG. 7). When the air conditioner A is in operation (Yes in Step # 101), the control unit 20 continues to monitor the operation state until the operation of the air conditioner A stops (No in Step # 102).

  When the operation of the air conditioner A is stopped (Yes in Step # 102), the control unit 20 displaces the louver 18 to the designated position (Step # 103). Then, the control unit 20 waits until the operation start time set in the on timer mode based on the time information obtained from the time measuring unit 21 (No in Step # 104).

  When the operation start time set in the on-timer mode is reached (Yes in step # 104), the control unit 20 starts operation in the set operation mode (step # 105) and ends the operation flow in the on-timer mode. (End of FIG. 7).

  On the other hand, in step # 101, when the air conditioner A is not in operation (air conditioning operation such as cooling operation, heating operation, and air blowing operation) (No in step # 101), the control unit 20 uses the current on-timer mode. It is determined whether or not the operation is after the cut-off timer mode (step # 106). When it is after the turn-off timer mode (Yes in Step # 106), the control unit 20 waits until the operation start time set in the on-timer mode without displacing the louver 18 (No in Step # 104). That is, when the turn-off timer mode and the on-timer mode are set during operation, the air conditioner A disables the louver 18 from the stop of the operation in the off-timer mode to the start of the operation in the on-timer mode.

  If the current operation in the on-timer mode is not after the off-timer mode (No in Step # 106), the control unit 20 determines whether or not a delay is set for the position displacement of the louver 18, that is, for a predetermined time set in advance. It is determined whether or not the louver 18 is displaced to the designated position after the elapse of time and before the start of the operation in the on timer mode (step # 107). When there is no delay setting (No in Step # 107), the control unit 20 immediately displaces the louver 18 to the designated position (Step # 103).

  When there is a delay setting (Yes in Step # 107), the control unit 20 waits for a predetermined time (for example, 10 minutes) (Step # 108), and then displaces the louver 18 to a specified position (Step # 103).

  Further, when the timer mode is set using the remote controller 30 in the air conditioner A (start of FIG. 8), the control unit 20 determines the air conditioner A until the operation stop time based on the time information obtained from the time measuring unit 21. Is continued (No in step # 201). When the operation stop time is reached (Yes in Step # 201), the control unit 20 stops the displacement of the louver 18 (Step # 202).

  Subsequently, the control unit 20 determines whether or not a delay is set with respect to the positional displacement of the louver 18, that is, whether or not the louver 18 is returned to the initial position after a predetermined time has elapsed (step #). 203). When there is no delay setting (No in Step # 203), the control unit 20 does nothing and ends the operation flow of the off timer mode (End in FIG. 8). That is, the air conditioner A stops the operation without returning the louver 18 to the initial position when the operation is stopped in the off timer mode.

  On the other hand, when there is a delay setting (Yes in Step # 203), the control unit 20 waits for a predetermined time (for example, 7 hours) (Step # 204), and then returns the louver 18 to the initial position (Step # 205). The operation flow of the mode is terminated.

  As described above, when the on-timer mode is set during the air conditioning operation such as the cooling operation, the heating operation, and the air blowing operation, the air conditioner A is stopped when the operation is stopped (for example, the user operates the remote controller 30 to operate the air When the stop of the harmonious operation is instructed), the louver 18 is displaced to the designated position set in advance, and when the cut-off timer mode is set, the operation is performed without returning the louver 18 to the initial position when the operation is stopped in the cut-off timer mode. Stop. Thereby, the air conditioner A does not drive the louver 18 when the operation is started or stopped in the timer mode. Therefore, generation of driving sound of the louver 18 at that time can be suppressed.

  The air conditioner A displaces the louver 18 to a specified position at the time of setting when the on-timer mode is set while the air-conditioning operation such as the cooling operation, the heating operation, and the air-blowing operation is stopped, or the cooling operation or the heating operation is performed. When the on-timer mode is set while the air-conditioning operation such as the air blowing operation is stopped, the louver 18 is displaced to the designated position after the elapse of a predetermined time set in advance and before the operation in the on-timer mode is started. As a result, during operation stop, the louver 18 is set not to be driven at the start of operation in the on-timer mode. Therefore, it is possible to suppress the generation of driving sound of the louver 18 at the start of air conditioning operation such as cooling operation, heating operation, and air blowing operation. In addition, the user disagrees with the on timer mode that the air conditioner operation such as the cooling operation, the heating operation, and the air blowing operation in which the louver 18 is displaced immediately after the operation instruction is performed by displacing the louver 18 after a predetermined time has elapsed. Can be prevented from being misunderstood.

  The air conditioner A returns the louver 18 to the initial position after elapse of a predetermined time when the timer mode is set. For example, after the user wakes up from sleep, the louver 18 is returned to the initial position. . Therefore, generation | occurrence | production of the drive sound of the louver 18 during sleep can be suppressed, and an unpleasant feeling is not felt also about the appearance of the indoor unit 1 after a user wakes up.

  Further, when the air conditioner A stops the air conditioner operation without returning the louver 18 to the initial position when the air conditioner operation such as the cooling operation, the heating operation, the air blowing operation or the like in the off timer mode is stopped, the louver 18 at the time of the stop operation is stopped. Is displayed on the remote controller 30. As a result, the user can notice that the louver has not returned to the initial position by looking at the remote controller 30 when waking up. Therefore, the generation of the driving sound of the louver 18 during sleep can be reliably suppressed, and the appearance of the indoor unit 1 after the user wakes up does not feel uncomfortable.

  Further, when the turn-off timer mode and the turn-on timer mode are set during operation, the air conditioner A makes the louver 18 undisplaceable from the stop of the operation in the turn-off timer mode to the start of the operation in the turn-on timer mode. Thereby, the louver 18 is not driven until the air conditioner A is stopped in the timer mode and then restarted. Therefore, it is possible to suppress the generation of driving sound of the louver 18 during that time.

  Thus, according to the configuration of the above embodiment of the present invention, when the air conditioner A starts the air conditioning operation such as the cooling operation, the heating operation, and the air blowing operation in the timer mode, or the cooling operation, the heating operation, and the air blowing. Generation of driving sound of the louver 18 when air conditioning operation such as operation is stopped can be suppressed. Therefore, it is possible to provide the air conditioner A that allows the user to obtain suitable sleep.

  Although the embodiments of the present invention have been described above, the scope of the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the invention.

  For example, only the on-timer mode described in the present embodiment is employed in the air conditioner, or only the off-timer mode described in the present embodiment is employed in the air conditioner, or the on-timer mode described in the present embodiment and Both of the off timer modes can be adopted for the air conditioner.

  In addition, the louver 18 of the indoor unit 1 of the air conditioner A according to the present embodiment has a horizontally long rectangle when viewed from the front and can swing on the lower side with the upper side extending in the horizontal direction as the rotation center, but the lower side rotates. It may be a louver that can swing on the upper side as the center, or a louver that can swing on the upper side and the lower side about the center in the vertical direction.
