Abstract

PROBLEM TO BE SOLVED: To efficiently send air to the entirety of objects of drying by increasing air volume per unit time within a sending-out range for drying in a dry mode of an air conditioner.SOLUTION: The air conditioner sends out air from an outlet by the rotation of an interior fan while a louver for varying a wind direction is disposed in an outlet. The air conditioner includes: a standard mode in which the louver oscillates in a predetermined first oscillation range and sends out air in a first sending-out range; and the dry mode in which the air volume per unit time in a second sending-out range that is narrower than the first sending-out range is greater than in the standard mode.

Description

  The present invention relates to an air conditioner having a drying mode in which air is blown into a room and air is blown to a drying target such as clothing.

  The air conditioner sucks indoor air, adjusts temperature and humidity, and then blows (discharges) air into the room. On the other hand, it is known that when wind is applied to wet clothing or the like, the drying time is shortened. This is thought to be because high-humidity air in the vicinity of clothing is blown away by blowing air. From the viewpoint of using the air conditioner as a dryer, there is an air conditioner equipped with a drying mode for drying clothes and the like. An example of an air conditioner having such a drying mode is described in Patent Document 1.

  Specifically, Patent Document 1 discloses a mode in which an air conditioner having an indoor fan and a compressor is subjected to a drying operation based on a command from an operation unit, such as a drying operation, a cooling operation mode, a blowing operation mode, and a heating operation mode. Describes a drying operation method of an air conditioner that varies the wind direction and swing control. With this configuration, the laundry is efficiently dried (see Patent Document 1: claims 1 to 3, paragraphs 0004 and the like).

JP 2004-279027 A

  In many cases, the air outlet of the air conditioner is positioned above laundry to be dried indoors (for example, laundry or covers dried by indoor laundry). Therefore, the invention described in the upper patent document 1 makes the air blow slightly downward (diagonally downward) in the drying mode. Some air conditioners are capable of switching the wind direction (delivery range) with a remote control device. Therefore, in the drying mode, the user may set the wind direction so that the wind hits the object to be dried by the remote control device.

  In recent years, sterilization and deodorization may be performed by blowing air. The applicant has a unique technique for releasing positive ions and negative ions into the air and sterilizing and deodorizing by releasing these ions. From the viewpoint of sterilization and deodorization, it is preferable to efficiently blow the wind containing ions over the entire object to be dried. However, in a conventional air conditioner, since a fine delivery range cannot be set and the delivery range is fixed, air may be blown to a range where there is no drying target in the delivery range by swing. In addition, if the setting is made to stop the swing in the dry mode, there is a high possibility that the entire clothing is not blown. Therefore, conventionally, there also exists a problem that it cannot blow efficiently over the whole drying object.

  However, in the invention of Patent Document 1, the delivery range is fixed regardless of whether it is a normal operation or a dry operation. Therefore, the problem of efficiently blowing air over the entire drying target cannot be solved.

  An object of this invention is to ventilate the whole drying object efficiently in dry mode.

  In order to achieve the above object, according to the present invention, in the air conditioner in which a louver that varies the wind direction is provided in the air outlet and air is sent out from the air outlet by the rotation of the indoor fan, the louver is a predetermined first. A normal mode in which the swing range is swung to send air to the first delivery range, and a drying mode in which the air volume per unit time in the second delivery range that is narrower than the first delivery range is greater than that in the normal mode. I decided to prepare.

  According to this configuration, the second delivery range in which the air volume per unit time is larger in the drying mode than in the normal mode is provided. Thereby, the 2nd delivery range which increases the air volume per unit time intentionally is provided, and more wind can be applied to the drying object (laundry, clothes, etc.) than before. Moreover, it becomes easy to spread a wind to the whole drying object by spraying many winds. Therefore, it is possible to quickly dry out the moisture to be dried and make it easy to dry.

  In the above air conditioner, it is preferable that a setting unit that receives an operation setting of the air conditioner is included, and the setting unit receives an operation of a user that varies the second sending range.

  According to this configuration, the setting unit receives an operation (setting instruction) for determining the second transmission range. Thereby, the range which swings a louver can be set, and the 2nd sending range can be matched with the range in which drying object exists. Therefore, it is possible to eliminate the blowing to a range where there is no drying target and efficiently blow and dry the entire drying target.

  In the above air conditioner, it is also preferable that the setting unit accepts an operation for changing an end of the second delivery range.

  According to this configuration, the setting unit receives an input for changing the end of the second transmission range (defining the end position). Thereby, the second transmission range can be set finely.

  In the air conditioner, in the drying mode, it is also preferable that the louver swings only in a second swinging range for sending air to the second delivery range.

  According to this configuration, in the dry mode, the louver swings so that the air is blown only in the delivery range (second delivery range) narrower than the delivery range in the normal mode. As a result, even if air is blown at the same air volume as in the normal mode, the second delivery range is narrower than in the normal mode, so the air volume per unit time in the second delivery range is greater than in the normal mode. Accordingly, it is possible to increase the air volume per unit time in the second delivery range in which the drying target is present, thereby making it easier to dry the drying target.

  In the drying mode, the louver swings in a drying swing range for sending air to a dry delivery range that includes the second delivery range and is wider than the second delivery range; It is also preferable to have a period of oscillating only in the second oscillating range for delivering air to the two delivering ranges.

  In the air conditioner described above, in the drying mode, the louver swings in a dry swing range that sends air to a dry delivery range that includes the second delivery range and is wider than the second delivery range. It is also preferred that the variable speed is slower when moving to the second delivery range than when sending out of the second delivery range.

  In the air conditioner described above, in the drying mode, the louver swings in a dry swing range that sends air to a dry delivery range that includes the second delivery range and is wider than the second delivery range. It is also preferable that the indoor fan has a higher rotational speed when being sent out to the second delivery range than when being sent outside the second delivery range.

  In the dry mode, the air is blown in a wider range than the second delivery range, but the air is intentionally blown in the second delivery range so that the air volume per unit time is larger than in the normal mode (a combination of any of these). May be). Thereby, the air volume per unit time blown to the 2nd sending range in which a drying object exists can be increased, and a drying object can be made easy to dry. Further, since the air is also blown over a range wider than the second delivery range, it is possible to blow away the high-humidity air that evaporates from the drying target and stays around the second delivery range, thereby making it easier to dry the drying target.

  In the above air conditioner, the dry delivery range is preferably the first delivery range.

  According to this configuration, the dry delivery range in the drying mode is the delivery range (first delivery range) in the normal mode. Thereby, it is possible to ensure the same air blowing capacity (delivery range) as in the normal mode even in the dry mode. Also, the drying mode does not give a sense of incongruity that the delivery range is significantly different from the normal mode.

  In the above air conditioner, it is also preferable that the louver has a wind direction that varies in the vertical direction, and that the upper limit position of the second swing range is gradually lowered in the drying mode.

  According to this configuration, in the drying mode, the upper limit position of the second delivery range gradually decreases. When the moisture of the drying target is dried, it is transmitted downward and it is difficult to dry the lower part, so that the air volume per unit time downward of the drying target can be increased. Therefore, the entire drying object can be quickly dried.

  The air conditioner preferably includes an ion generator that generates ions, and the blown air from the outlet includes ions generated by the ion generator.

  According to this configuration, the blown air contains ions. Thereby, the ion which has bactericidal property and deodorant property can be blown out indoors. Therefore, it is possible to perform sterilization of the object to be dried, prevent odor generation from the object to be dried, and perform comfortable drying.

  According to the present invention, it is possible to intentionally increase the air volume per unit time in the delivery range (second delivery range) for drying in the drying mode than in the normal mode. And it blows efficiently over the whole drying object, makes it easy to dry the drying object, and realizes a quick and comfortable drying mode.

  In order to dry the object to be dried efficiently and quickly, it is ideal to effectively increase the air volume per unit time in the delivery range to the object to be dried. However, the conventional air conditioner has a problem that the air volume per unit time is not actively increased for drying (for example, the above-described conventional invention is more actively sent to the drying target than the normal operation). Is not intended to increase the air flow per unit time.) In addition, conventionally, there is a problem that air cannot be efficiently blown over the entire drying target. Therefore, in each embodiment, the air volume per unit time in the delivery range for drying is increased in the drying mode, and the entire drying target is efficiently blown. An embodiment of the present invention will be described with reference to FIGS. First, the first embodiment will be described with reference to FIGS.

  Here, the unit time will be described. The unit time is a time that can be arbitrarily determined. In the example described below, 10 minutes and 2 minutes are taken as examples. The unit time is a certain interval (for example, 10 minutes) so that it can be understood that the air volume to the delivery range for drying in the drying mode (explained as the second delivery range R in the following example) is clearly larger than that in the normal mode. Or 2 minutes). The unit time may be 1 minute or 1 hour, and is not limited to 10 minutes or 2 minutes. If the total air volume at a certain interval is divided by a certain interval of seconds (for example, 600 seconds for 10 minutes, 120 seconds for 2 minutes), the air volume per unit time can be obtained with 1 second as a unit time. Can do. Also, by dividing the total air volume at a certain interval by a certain interval (for example, 10 for 10 minutes, 2 for 2 minutes), the air volume per unit time can be obtained with 1 minute as a unit time. . In this way, the unit time can be arbitrarily determined, and the air volume to the delivery range for drying can be compared in the drying mode in the normal mode and the drying mode. Note that the air volume can be obtained from the specifications of the indoor fan 23 described later and the rotation speed (the volume of air sent out with respect to the rotation speed).

(First embodiment)
First, the outline | summary of the air conditioner 1 which concerns on 1st Embodiment is demonstrated using FIG. Drawing 1 is a mimetic diagram showing an example of air harmony machine 1 concerning a 1st embodiment of the present invention, (a) shows an example of indoor part 2, and (b) shows an example of outdoor part 3. .

  As shown to Fig.1 (a), the air conditioner 1 of this embodiment contains the indoor part 2 (indoor unit). The indoor part 2 sucks indoor air and blows out the air after heat exchange into the room. For example, the air outlet 21 of the indoor portion 2 is provided below the entire surface of the indoor portion 2.

  Moreover, as shown in FIG.1 (b), the air conditioner 1 of this embodiment contains the outdoor part 3 (outdoor unit). The outdoor unit 3 exchanges refrigerant with the indoor unit 2 and exchanges heat with outdoor air.

(Hardware configuration of air conditioner 1)
Next, an example of the hardware configuration of the air conditioner 1 according to the first embodiment will be described with reference to FIG. FIG. 2 is a block diagram illustrating an example of a hardware configuration of the air conditioner 1 according to the first embodiment.

  As described above, the air conditioner 1 of the present embodiment includes the indoor portion 2 and the outdoor portion 3. Therefore, the interior 2 will be described. A receiving unit 42 for receiving a signal indicating an operation or setting instruction from the remote control device 41 is provided in the indoor portion 2. The remote control device 41 is provided with a transmitter that transmits signals by infrared or wireless, and the receiver 42 receives infrared or radio waves. Thereby, the user can operate the operation of the air conditioner 1 with the remote control device 41 (details of the remote control device 41 will be described later).

  In addition, a panel-like operation unit 43 may be provided in the indoor portion 2 so that operations and setting instructions can be performed without depending on the remote control device 41. Therefore, the remote control device 41, the receiving unit 42, and the operation unit 43 function as the setting unit 4 that receives the settings of the air conditioner 1. Moreover, the air conditioner 1 of this embodiment is provided with the display part 22 which displays various information, such as the driving | running state of the air conditioner 1, with a display lamp, a display panel, etc.

  The indoor section 2 includes a control section 5 that controls the operation of the air conditioner 1. For example, the control unit 5 includes a CPU 51 as an arithmetic processing unit, a storage unit 52 (including RAM and ROM, for example) that stores a control program and control data for the air conditioner 1, and a time measuring unit 53 that measures time. It is a mounted circuit board. In particular, in order to perform air blowing different from the normal mode with respect to the second delivery range R provided in the drying mode, the storage unit 52 stores data and programs related to the air blowing method in the drying mode. The control unit 5 receives signals from the receiving unit 42 and the operation unit 43 and controls the air conditioner 1 in accordance with a user instruction. Further, the control unit 5 gives a display signal to the display unit 22.

  An indoor fan motor 23M that rotates the indoor fan 23 and the indoor fan 23 to blow out heat-exchanged air into the room from the air outlet 21 is disposed in the indoor part 2. The controller 5 controls the driving of the indoor fan motor 23M. Specifically, the control unit 5 controls ON / OFF of the indoor fan motor 23M and the rotational speed of the indoor fan motor 23M. In this embodiment, an example in which the control unit 5 controls the operation of the indoor fan motor 23M will be described. However, a drive circuit for the indoor fan motor 23M is separately provided outside the control unit 5, and the control unit 5 instructs the drive circuit. The controller 5 may indirectly control the operation of the indoor fan motor 23M.

  In addition, a louver 24 for adjusting the blowing direction in the vertical direction of the air blown by the indoor fan 23 is provided in the indoor portion 2. Further, a louver motor 24M that moves the louver 24 to swing the blowing direction in the vertical direction is provided in the indoor portion 2. The controller 5 can control the sending range by controlling the operation of the louver motor 24M.

  Further, left and right louvers 25 are provided in the indoor portion 2 in order to adjust the blowing direction in the left and right direction of the air blown by the indoor fan 23. A plurality of plates extending in the vertical direction in the vicinity of the air outlet 21 as the left and right louvers 25 are arranged in the left and right direction. A left and right louver motor 25M that moves the left and right louvers 25 to adjust the blowing direction in the left and right directions is provided in the indoor portion 2. The controller 5 can control the sending range by controlling the operation of the left and right louver motor 25M.

  An indoor heat exchanger 26 that exchanges heat with air sucked into the indoor portion 2 by the indoor fan 23 is provided in the indoor portion 2. Further, a temperature detection unit 27 for detecting the room temperature is provided. The temperature detection unit 27 is a sensor whose output value (for example, voltage value) varies depending on the temperature. The controller 5 recognizes the room temperature based on the output voltage of the temperature detector 27. For example, a table indicating the relationship between the output value of the temperature detection unit 27 and the temperature is stored in the storage unit 52. And the control part 5 controls the air conditioner 1 so that the set temperature may be approached, for example, the operation is paused when the set temperature is reached.

An ion generator 28 is provided in the indoor portion 2. The ion generator 28 is provided in the air passage from the room air inlet to the outlet 21. For example, the ion generator 28 generates plasma discharge of positive ions (H ⁺ (H ₂ O) _m (m is a natural number)) and negative ions (O ₂ ⁻ (H ₂ O) _n (n is a natural number)) in the natural world. Produced by and released into the air. As a result, a wind containing positive ions and negative ions is blown out. The action of allergic substances, viruses, and bacteria can be reduced by the wind containing ions, and the air conditioner 1 can have a sterilization and deodorizing function. The control unit 5 is connected to the ion generator 28 and can switch ON / OFF of driving of the ion generator 28.

  Next, the outdoor unit 3 will be described. For example, the outdoor 3 is installed on the outdoor ground. The outdoor unit 3 includes a compressor 31 and a loose compressor driving circuit 32 for operating the compressor 31. The controller 5 gives an instruction to the compressor drive circuit 32 to control the operation of the compressor 31.

  An outdoor fan 33 and an outdoor fan motor 33M are provided in the outdoor 3. The control unit 5 controls the outdoor fan motor 33M, and controls suction and blowing in the outdoor 3. The outdoor fan motor 33M sucks air for exchanging heat by rotating the outdoor fan 33 into the outdoor 3. Then blow out. The outdoor fan motor 33M is driven to rotate the outdoor fan 33 so that air is blown to the outdoor heat exchanger 34 provided in the outdoor 3 and the air is discharged to the outside. Thereby, heat exchange of the air sucked into the exterior 3 is performed.

  A four-way valve 35 and a decompressor 36 (for example, an electronic expansion valve or a capillary tube) constituting the refrigeration cycle 29 are provided in the outdoor part 3. The control unit 5 controls the four-way valve 35 to switch the flow direction of the refrigerant compressed by the compressor 31 according to the heating operation / cooling operation (dehumidifying operation). The decompressor 36 maintains a pressure difference between the high-pressure (heat radiation) side refrigerant compressed by the compressor 31 and the expanded low-pressure (heat absorption) side refrigerant.

(Remote control device 41)
Next, an example of the remote control device 41 according to the first embodiment will be described with reference to FIG. FIG. 3 shows an example of the remote control device 41 according to the first embodiment. FIG. 3A shows an example of a state where the cover 411 is closed, and FIG. 3B shows an example of a state where the cover 411 is opened.

  The remote control device 41 has a display unit 410 (for example, a liquid crystal display unit) indicating the setting contents and the like on the upper front side. The remote control device 41 includes five basic buttons for instructing basic operation of the air conditioner 1. Specifically, a cooling button B1 that is pressed when the air conditioner 1 is operated by cooling, a heating button B2 that is pressed when the air conditioner 1 is operated by heating, a stop button B3 for stopping the operation, and air by dehumidification A dehumidifying button B4 that is pressed when the conditioner 1 is operated and an automatic operation button B5 that is pressed when the air conditioning operation is automatically performed according to the set temperature are provided. Below the basic buttons, a temperature setting button B6 and a humidity setting button B7 for setting a desired temperature and humidity are provided.

  Further, a button for performing finer settings is provided below the cover 411. When setting the wind direction and timer, the user opens the cover 411 to expose various buttons. Among the buttons that appear when the cover 411 is opened, an up / down air direction button B8 for setting the up / down air direction and a left / right air direction button B9 for setting the left / right air direction are provided.

  In addition, a life dehumidifying button B10 for instructing operation in a drying mode for drying clothes is provided in the buttons (a button attached with a drying mode may be provided). By pressing the life dehumidifying button B10, a signal indicating that the operation in the dry mode should be performed is transmitted from the remote control device 41 to the receiving unit 42 in the indoor portion 2. The signal received by the receiving unit 42 is sent to the control unit 5. As a result, the control unit 5 recognizes that it should be operated in the dry mode.

(Normal mode and Dry mode)
Next, the outline of the ventilation in the normal mode and the drying mode of the first embodiment will be described with reference to FIG. FIG. 4 is an explanatory diagram for explaining a delivery range in the drying mode and a delivery range in the normal mode in the first embodiment.

  By operating the louver motor 24M, the control unit 5 can blow air from the outlet 21 in the vertical direction in the range from the horizontal direction (0 degrees) to the substantially vertical downward direction. In the following description, the horizontal direction is assumed to be 0 degree as a reference, and the air conditioner 1 of the present embodiment is explained as being capable of blowing air in the range of about 0 degree to about -90 degrees.

  When the drying mode is not instructed, the control unit 5 operates the air conditioner 1 in the normal mode. In other words, it can be said that the operation mode other than the drying mode is the normal mode regardless of heating or cooling. Then, as shown by a broken line in FIG. 4, the control unit 5 controls the louver motor 24M to swing the louver 24 (by swinging the louver 24 in the first swing range), for example, in the normal mode. Air is blown in the range of about 0 degrees to about -90 degrees in the vertical direction. In other words, the transmission range in the normal mode (hereinafter referred to as “first transmission range”) is about 0 degree to about −90 degrees.

  On the other hand, in the first embodiment, as shown in FIG. 4, the delivery range in the dry mode (hereinafter referred to as “second delivery range R” below the range shown by the solid line in FIG. 4) is the delivery range in the normal mode. Narrower than (first delivery range). Usually, the drying object D such as laundry is hung on a clothesline or a hanger, and is rarely dried at a height enough to attach to the ceiling. Therefore, normally, even if it blows in the horizontal direction of the blower outlet 21, the drying object D does not exist. Therefore, in the drying mode, the delivery range is narrower than in the normal mode, and air blowing to the range where the drying target D does not exist is eliminated (reducing blind spots). Then, the user finely adjusts the position where the drying target D is dried so that the wind hits the entire drying target D corresponding to the narrowed delivery range.

  Although the 2nd sending range R can be defined arbitrarily, for example, it can be set as a swing width of 40 to 45 degrees (for example, a range of 20 to 60 degrees, and a range of 30 to 75 degrees). Specifically, the control unit 5 controls the louver motor 24M so as to be reversed when the louver 24 rotates about 40 to 45 degrees. Therefore, in the air conditioner 1 of the present embodiment, the swing width (second delivery range R) in the drying mode is about ½ of the swing width (first delivery range) in the normal mode. Note that the optimum second delivery range R may vary depending on the model of the air conditioner 1, so the swing width (width of the second delivery range R) in the second delivery range R in the drying mode is the same as that of the air conditioner 1. It is determined appropriately according to the model.

  Thus, in this embodiment, since the delivery range in the drying mode is narrower than in the normal mode, the swing speed (swinging speed) of the louver 24 is the same as that in the normal mode, and the rotation speed of the indoor fan 23 is also the normal mode. If they are the same, the air volume per unit time in the second delivery range R can be increased. For example, in the normal mode, the louver 24 performs 10 reciprocating swings so as to blow air to the first delivery range in 10 minutes (first delivery range 10 reciprocation. The first delivery range includes the second delivery range R). Therefore, 10 reciprocations are also sent to the second delivery range R). At this time, it is assumed that the second transmission range R is a half of the first transmission range. Then, in 10 minutes in the drying mode, the louver 24 can swing 20 times so as to blow air to the second delivery range (20 round trips to the second delivery range). Therefore, in the unit time of 10 minutes, the air volume per unit time in the drying mode can be increased as compared with the normal mode.

  Further, the control unit 5 may control the indoor fan motor 23M so that the number of rotations of the indoor fan motor 23M in the drying mode is greater than the number of rotations of the indoor fan motor 23M in the normal mode. At least equivalent to the strongest wind in normal mode. In this way, the air volume per unit time in the second delivery range R in the second delivery range R in the drying mode can be increased more reliably than in the normal mode.

(Adjustment of second transmission range R)
Next, adjustment of the second transmission range R in the first embodiment will be described with reference to FIG. FIG. 5 is an explanatory diagram for explaining an example of adjustment of the second transmission range R in the first embodiment.

  For example, as shown in the uppermost drawing of FIG. 5, when the drying target D is installed and the drying mode is executed, there is a case where wind does not hit the entire drying target D. In the air conditioner 1 of this embodiment, when the drying mode is selected, the air conditioner 1 is set in advance so that air is blown with a width of about 40 to 45 degrees with the central angle being about -45 degrees. In other words, the second transmission range R is preset, for example, control data for setting the transmission range to about 25 degrees to about 70 degrees is stored in the storage unit 53 (preset). When the drying mode is selected, the control unit 5 reads the preset value, controls the louver motor 24M, swings the louver 24 within a predetermined second swing range, and sets a predetermined first value. 2 Air is sent to the delivery range R.

  However, as shown in the uppermost drawing of FIG. 5, there is a case where it is desired to shift the second delivery range R so that the air is blown to the entire drying object D. Therefore, in the present embodiment, the second sending range R can be adjusted by shifting the center angle in the swing.

  Specifically, when adjusting the second delivery range R, the up / down air direction button B8 on the remote control device 41 is pressed. Thereby, the adjustment of the second transmission range R is started. When the up / down air direction button B8 is pressed, the control unit 5 controls the louver motor 24M to swing the louver 24 beyond the predetermined second delivery range R (so that the entire area where air can be blown is blown).

  For example, when it is desired to set the second sending range R downward from the preset position, the up / down air direction button B8 is pressed when the louver 24 is moving downward and reaches a desired position. Thereby, a lower limit is set. For example, when it is desired to make the second sending range R upward from the preset position, the up / down air direction button B8 is pressed when the louver 24 is moving upward and reaches a desired position. Thereby, an upper limit is set. Thus, the blowing angle of the second delivery range R (the center angle of the second delivery range R) can be changed.

  Even if the second delivery range R is adjusted, air is blown with a predetermined delivery range width (for example, a width of about 40 to 45 degrees). In other words, the control unit 5 causes the air to blow without changing the second swing range (swing angle) of the louver 24 and the width (width) of the second delivery range R itself. Therefore, the upper limit is automatically determined when the lower limit is set, and the lower limit is automatically set when the upper limit is set. Thereby, the 2nd delivery range R can be adjusted and a wind can be applied to the drying object D uniformly.

(Processing flow in drying mode)
Next, a processing flow in the drying mode in the first embodiment will be described with reference to FIG. FIG. 6 is a flowchart illustrating an example of a processing flow in the drying mode according to the first embodiment.

  The start of FIG. 6 is that the air conditioner 1 is in an operating state. For example, the controller 5 confirms that the life dehumidification button B10 is pressed by the remote control device 41 and the mode of the air conditioner 1 should be shifted to the drying mode. It is the time of recognition.

  When shifting to the drying mode, the control unit 5 controls the louver motor 24M to cause the louver 24 to swing so that air is blown within the predetermined second delivery range R (step # 1). In other words, the control unit 5 swings the louver 24 in the second swing range. Next, if the ion generator 28 is not operating, the controller 5 operates the ion generator 28 (step # 2). Thereby, sterilization etc. can be performed by including ions in the air for drying. Furthermore, the control unit 5 confirms whether or not it is operating with heating (step # 3).

  If the operation is performed by heating (Yes in Step # 3), the control unit 5 operates the compressor 31 and the outdoor fan 33 so that the rotation speed of the indoor fan motor 23M is higher than that in the normal mode while performing heating. Increase. Thereby, it is set as the heating strong wind driving | running state in which the air volume from the blower outlet 21 increases more than normal mode (step # 4). For example, the control unit 5 increases the air volume in the drying mode rather than the largest air volume in the normal mode.

  Then, the controller 5 checks whether or not a predetermined first drying time has elapsed since the start of the strong wind operation (step # 5). If it has not elapsed (No in step # 5), the flow returns to step # 4. If there is an instruction for adjusting the second sending range R, such as the remote control device 41 pressing the up / down air direction button B8 during the loop of step # 4 and step # 5, the second instruction is input in accordance with the user's instruction input. The angle of the sending range R (center angle) is changed.

  If the first drying time has elapsed, the control unit 5 controls the louver motor 24M and moves the louver 24 to fix the blowing direction horizontally (step # 6). Then, the controller 5 performs the dehumidifying operation for a predetermined first dehumidifying time (step # 7). In the dehumidifying operation, similarly to the cooling operation, the control unit 5 lowers the temperature of the indoor heat exchanger 26 to absorb heat and causes the outdoor heat exchanger 34 to exhaust heat. The indoor heat exchanger 26 condenses moisture in the air and dehumidifies it. And in dehumidification of dry mode, an air volume is dropped rather than a heating strong wind driving | running state.

  When the air is blown to the drying object D, the indoor humidity increases (for example, the indoor humidity may exceed 90% after one hour of air blowing). Therefore, after drying for the first drying time, the control unit 5 performs dehumidifying operation for the first dehumidifying time. The reason why the louver 24 is set in the horizontal direction is to prevent the drying target D from being cooled and dampened because cold air is blown out from the outlet 21 in the dehumidifying operation.

  On the other hand, if the heating operation is not performed (No in step # 3 if the operation is cooling or dehumidifying), the control unit 5 stops the compressor 31 and the outdoor fan 33, and does not perform cooling or dehumidification. The rotational speed of 23M is increased from the normal mode. When the temperature of the drying object D is lowered by blowing cold air, the controller 5 may return and get wet, so that the control unit 5 stops heat exchange. As a result, the control unit 5 does not cool the wind from the outlet 21 (without cooling or dehumidification), and makes a blowing strong wind operation state in which only the blowing is performed and the air volume is increased from the normal mode (step # 8). . For example, the control unit 5 increases the air volume in the drying mode rather than the largest air volume in the normal mode.

  Then, the control unit 5 checks whether or not a predetermined second drying time has elapsed from the start of the blowing high wind operation (step # 9). If it has not elapsed (No in step # 9), the flow returns to step # 8. If there is an instruction to adjust the second sending range R, such as the remote control device 41 pressing the up / down air direction button B8 during the loop of step # 8 and step # 9, the second instruction is input in accordance with the user's instruction input. The angle of the sending range R (center angle) is changed.

  If the second drying time has elapsed, the control unit 5 controls the louver motor 24M to move the louver 24 and fix the blowing direction horizontally (step # 10). Then, the control unit 5 performs the dehumidifying operation for a predetermined second dehumidifying time (step # 11). Although the time of the dehumidifying operation is different, the contents of the dehumidifying operation are the same as in step # 6 and step # 7.

  Here, in the air conditioner 1 of this embodiment, the time (1st drying time and 2nd drying time) which ventilates the drying object D differs in the case of heating operation and the case of cooling or dehumidifying operation. Further, even in the dehumidifying operation after the air is blown to the second delivery range R and dried, the time for dehumidification is different between the heating operation and the cooling or dehumidifying operation (the first dehumidifying time and the second dehumidifying time). Dehumidification time).

  For example, when the air conditioner 1 is in the heating operation (heating mode), the air heated by the heating is blown out to the second delivery range R for the first 3/4 of the total time of the drying mode, During the remaining ¼ time, the room humidity is lowered by dehumidifying operation. For example, assuming that the operation time in the dry mode is predetermined as 4 hours in total, the heating and strong wind operation is performed for about 3 hours and the dehumidifying operation is performed for about 1 hour. In the heating drying mode, the ratio of the time of the heating strong wind operation and the dehumidifying operation can be arbitrarily determined. For example, the first drying time (heating strong wind operation time)> the first dehumidifying time (heating The ratio of time may be determined under the condition of (dehumidifying operation time).

  On the other hand, in the drying mode when the air conditioner 1 is not in the heating operation (cooling or dehumidification), air that does not exchange heat is blown out to the second delivery range R for the first quarter of the total time of the drying mode. During the remaining 3/4 time, the humidity in the room is reduced by dehumidifying operation (the temperature can also be reduced). For example, assuming that the operation time in the dry mode is predetermined as 4 hours in total, the blowing strong wind operation is performed for about 1 hour and the dehumidifying operation is performed for about 3 hours. In the drying mode of cooling or dehumidification, the ratio of the time of the blowing strong wind operation and the dehumidifying operation can be arbitrarily determined. For example, the second drying time (the time of the blowing strong wind operation) <the second dehumidifying time (heating) The ratio of the time may be determined under the condition of the time of dehumidifying operation other than the above.

  Here, if the cold wind is continuously blown to the drying object D, the drying object D is cooled and moisture is easily attached to the drying object D. Therefore, the first drying time (time of heating strong wind operation)> second drying time (time of blowing strong wind operation) is set. Accordingly, if the heating operation in the drying mode is the same as the cooling and dehumidifying operation time, the first dehumidifying time (dehumidifying operation time in heating) <second dehumidifying time (dehumidifying operation time other than heating) ) Relationship is derived.

  Specifically, for each operation state (heating, cooling, dehumidification), data (for example, data) that defines the type and amount of air blowing, the first drying time, the second drying time, the first dehumidifying time, and the second dehumidifying time. Table format) is stored in the storage unit 52. The control unit 5 realizes a drying mode according to the situation along the data stored in the storage unit 52.

  If dehumidification is performed during the first dehumidification time or during the second dehumidification time (after step # 7 and step # 11), this flow ends. For example, when this flow ends, the control unit 5 may set the operation mode of the air conditioner 1 to the normal mode or stop the operation.

  In this way, the air conditioner 1 of the present embodiment is provided with the louvers (louvers 24 and left and right louvers 25) that change the wind direction at the air outlet 21, and the air conditioner sends out air from the air outlet 21 by the rotation of the indoor fan. In the machine 1, a normal mode in which the louver swings in a predetermined first swing range to send air to the first delivery range, and a unit time in a second delivery range R that is narrower than the first delivery range. It has a drying mode in which the air volume is higher than that in the normal mode. Thereby, the 2nd delivery range R which increases the air volume per unit time intentionally is provided, and more wind can be applied to the drying object (laundry, clothes, etc.) than before. Moreover, it becomes easy to spread a wind to the whole drying object by spraying many winds. Therefore, it is possible to quickly dry out the moisture to be dried and make it easy to dry.

  In addition, the air conditioner 1 includes a setting unit 4 (operation unit 43, reception unit 42, remote control device 41) that receives operation settings of the air conditioner 1, and the setting unit 4 varies the second sending range R. Accept user operations. Thereby, the range which swings a louver can be set, and the 2nd sending range R can be matched with the range where drying object exists. Therefore, it is possible to eliminate the blowing to a range where there is no drying target and efficiently blow and dry the entire drying target.

  Specifically, the setting unit 4 (the operation unit 43, the reception unit 42, the remote control device 41) receives an operation for changing the end of the second transmission range R. Thereby, the 2nd sending range R can be set up finely. For example, the setting unit 4 includes a remote controller including a wind direction button for setting the wind direction and a receiving unit 42 that receives a signal from the remote controller. Then, the setting unit 4 accepts an input for determining the end position of the second sending range R (for example, pressing of the up / down wind direction button B8), and the control unit 5 maintains the width of the second sending range R while inputting the input end. The position of the second delivery range R is changed so that the position becomes the end of the second delivery range R. As a result, the second sending range R can be set using the wind direction button provided in the remote control device 41 conventionally. In other words, the actual second transmission range R can be set by changing the meaning of the buttons provided in the remote control device 41 (having another meaning), and a button for determining the second transmission range R is selected. It is not necessary to provide a new one.

  In the drying mode, the louver (louver 24 or the like) swings (swings) only in the second swinging range for sending air to the second delivery range R. In other words, the control unit 5 swings the louver 24 so that air is blown in the second delivery range R that is narrower than the delivery range in the normal mode in the dry mode. Thereby, even if it blows with the same air volume as in the normal mode, the second delivery range R is narrower than that in the normal mode. Therefore, in the second delivery range R, the air volume per unit time is larger than in the normal mode. Accordingly, it is possible to increase the air volume per unit time in the second delivery range R where the drying target exists, and to make the drying target easy to dry.

    Moreover, the air conditioner 1 is provided with the ion generator 28 which generates ion, and the blowing air from the blower outlet 21 contains the ion which the ion generator 28 generated. Since ions can be included in the blown air, ions having sterilizing and deodorizing properties can be blown into the room. Therefore, it is possible to perform sterilization of the object to be dried, prevent odor generation from the object to be dried, and perform comfortable drying.

(Second Embodiment)
Next, the air conditioner 1 which concerns on the 2nd Embodiment of this invention is demonstrated using FIG. FIG. 7 is an explanatory diagram for explaining air blowing in the drying mode according to the second embodiment. In FIG. 7, for the sake of convenience, the drying object D is indicated by a broken line.

  The air conditioner 1 of the second embodiment differs from the first embodiment in the air blowing method in the drying mode, but the processing flow in the hardware itself and in the drying mode may be the same. In view of this, parts common to the first embodiment will be used unless otherwise described, and will not be described or illustrated.

  As shown in FIG. 7, in the second embodiment, a second delivery range R (an example of the upper limit and the lower limit of the second delivery range R is shown by a solid line in FIG. 7) is narrower than the delivery range in the normal mode. The provided points are the same as in the first embodiment. For example, the range of the second delivery range R is a swing width of about 40 to 45 degrees.

However, in the present embodiment, in the drying mode, air is blown in a range (dry delivery range) that includes the second delivery range R and is wider than the second delivery range R. In the present embodiment, the dry delivery range is described as being the same range as the delivery range in the normal mode (first delivery range). In other words, even in the drying mode, the control unit 5 swings the louver 24 in the first swing range (= dry swing range) and blows air in the range of about 0 ° to about −90 ° (dry in FIG. 7). An example of the upper limit and the lower limit of the sending range is shown by a broken line).

  In the second embodiment, the control unit 5 performs one or more reciprocations of the swing S2 for only the second delivery range R for one reciprocation of the swing S1 to the dry delivery range (first delivery range). (Two times in FIG. 7). In other words, in this embodiment, a period (time) for blowing air to the dry delivery range and a period (time) for blowing air to the second delivery range R are provided. Specifically, in the second embodiment, when the control unit 5 blows air once in a range wider than the second delivery range R (dry delivery range), one or more times, the second delivery range R The louver 24 is swung (oscillated) so that only air is blown.

  In addition, in the combination of the ventilation in dry mode, it is good also considering the ventilation to the dry delivery range as 1 time and the ventilation to the 2nd delivery range R as 1 time. Moreover, it is good also considering the ventilation to the dry delivery range as 2 times, and the ventilation to the 2nd delivery range R as 3 times. Further, the number of times of air blowing to the dry sending range and the number of times of air blowing to the second sending range R may not be fixed. That is, the louver 24 swings so that the dry delivery range (first delivery range) and the air blowing only to the second delivery range R are combined during a unit time. In other words, in the drying mode, the louver 24 blows air only to the second delivery range R (at least once) while blowing air to the dry delivery range during unit time.

  Thus, in this embodiment, when the swing speed (swinging speed) of the louver 24 is the same as that in the normal mode and the rotation speed of the indoor fan 23 is the same as that in the normal mode in the dry mode, the second delivery range is set in the dry mode. The frequency | count of ventilation with respect to R is increased more than the dry delivery range (1st delivery range). Thereby, the air volume per unit time in the 2nd sending range R can be increased.

  For example, it is assumed that the swing speed (swinging speed) of the louver 24 and the rotation speed of the indoor fan 23 are the same in the drying mode and the normal mode. In the normal mode, the louver 24 swings twice so as to blow into the dry delivery range (the first delivery range, the range of the swing S1) for 2 minutes (two round trips to the dry delivery range). Since the second delivery range R is included in the dry delivery range, two reciprocating blows with respect to the second delivery range R). On the other hand, in the dry mode, it is assumed that the second delivery range R is about one half of the dry delivery range. Further, in the drying mode, the second delivery of the swing S2 is performed after one reciprocation swing (one reciprocation to the dry delivery range) for 2 minutes so that the louver 24 blows to the dry delivery range of the swing S1. It is assumed that the swing for blowing air to the range R (one reciprocating air flow to the second delivery range R) is repeated twice. If it does so, three reciprocal sending will be performed with respect to the 2nd sending range R in dry mode between simple reciprocation and 2 reciprocating sending to the dry sending range of swing S1 in normal mode. Therefore, the air volume per unit time (for example, 2 minutes) in the drying mode can be increased as compared with the normal mode.

  Thereby, intentional concentration of the air blow to the second delivery range R is performed. And while making it easy to dry the drying object D, the high humidity air which stagnates around the 2nd delivery range R can be blown off, and the drying object D can be made easy to dry. Therefore, the air volume per unit time in the second delivery range R is larger than that in the normal mode when air is blown in the range of 0 degrees to about -90 degrees.

  In the second embodiment, the second sending range R can be adjusted similarly to the first embodiment. The processing flow in the drying mode may be the same as that in the first embodiment. However, in the heating strong wind operation state (step # 4) or the blowing strong wind operation state (step # 8) (see FIG. 7), In the first embodiment, the air is blown only in the second delivery range R. In the second embodiment, the number of swings of the blow to the second delivery range R is increased, and the blow itself is more than the second delivery range R. Is also made in a wide range (dry delivery range).

  In this way, in the drying mode, the louver swings in the drying swing range in which air is sent to the dry delivery range that includes the second delivery range and is wider than the second delivery range, and the second delivery. The range R has a period of swinging only in the second swinging range in which air is sent out. In other words, the control unit 5 swings the louver 24 so that air is blown into a dry delivery range wider than the second delivery range R in the dry mode, and the second delivery range R has a unit more than in the normal mode. The air is blown so that the air volume per hour increases. In the dry mode, the air is blown in a range wider than the second delivery range R, but the air is intentionally blown in the second delivery range R so that the air volume per unit time is larger than that in the normal mode. Thereby, the air volume per unit time blown to the 2nd delivery range R in which a drying object exists can be increased, and a drying object can be made easy to dry. In addition, since air is blown over a wider range than the second delivery range R, it is possible to blow away high-humidity air that evaporates from the drying target and stays around the second delivery range R, thereby making it easier to dry the drying target. .

  In the air conditioner 1, the dry delivery range is the first delivery range (the delivery range in the normal mode). Thereby, it is possible to ensure the same air blowing capacity (delivery range) as in the normal mode even in the dry mode. Also, the drying mode does not give a sense of incongruity that the delivery range is significantly different from the normal mode.

(Third embodiment)
Next, the air conditioner 1 which concerns on the 3rd Embodiment of this invention is demonstrated using FIG. FIG. 8 is an explanatory diagram for explaining air blowing in the drying mode in the third embodiment.

  The air conditioner 1 of the third embodiment differs from the first and second embodiments in the air blowing method in the drying mode, but the processing flow in the hardware itself and in the drying mode may be the same. Therefore, the parts common to the first and second embodiments are used unless otherwise described, and the description and illustration are omitted.

  As shown in FIG. 8, in the second embodiment, the second delivery range R (an example of the upper limit and the lower limit of the second delivery range R is shown by a solid line in FIG. 7) is narrower than the delivery range in the normal mode even in the dry mode. The provided points are the same as in the first and second embodiments. For example, the range of the second delivery range R is a swing width of about 40 to 45 degrees.

  However, in the present embodiment, in the dry mode, the air is blown in the range including the second delivery range R and wider than the second delivery range R (dry delivery range = R + 2R1). In the present embodiment, the dry delivery range is described as being the same range as the delivery range in the normal mode (first delivery range). In other words, even in the drying mode, the control unit 5 swings the louver 24 in the first swing range (= dry swing range) and blows air in the range of about 0 ° to about −90 ° (dry in FIG. 7). An example of the upper limit and the lower limit of the sending range is shown by a broken line).

  In the third embodiment, the control unit 5 performs the swing itself so that air is delivered to the dry delivery range. In the second delivery range R, the control unit 5 controls the louver motor 24M to perform the swing. The speed (variable speed of the louver 24, more specifically, the rotational speed of the louver motor 24M) is lowered from the range R1 other than the second delivery range R. Thereby, intentional concentration of the air blow to the second delivery range R is performed. Therefore, the air volume per unit time in the second delivery range R is larger than that in the normal mode when air is blown in the range of 0 degrees to about -90 degrees.

  As described above, in this embodiment, the swing speed (swinging speed) of the louver 24 is slowed when the louver 24 is sent to the second delivery range R in the drying mode. Thereby, the air volume per unit time in the 2nd sending range R can be increased.

  For example, it is assumed that the rotation speed of the indoor fan 23 is the same in the drying mode and the normal mode. In the normal mode, during about 2 minutes, the louver 24 swings twice so as to blow into the dry delivery range (the first delivery range, the range of the swing S1) (two round trips to the dry delivery range). Since the second delivery range R is included in the first delivery range, one-way about 30 seconds, and the second delivery range R is also sent twice). On the other hand, in the dry mode, it is assumed that the second delivery range R is about one half of the dry delivery range. In the dry mode, the louver 24 swings at the same speed as in the normal mode except for the second delivery range R (the required time on one way is about 15 seconds), and in the second delivery range R, it is 1/3 of the normal mode. Suppose that it swings at a speed (the time required for one way is about 45 seconds). Accordingly, for example, in the drying mode, the louver 24 swings once in a reciprocating manner so as to blow into the dry delivery range (the first delivery range, the range of the swing S1) for about 2 minutes (to the dry delivery range). 1 reciprocating blow).

  Then, by simple calculation, in the drying mode, the number of swings of the louver 24 per unit time (for example, 2 minutes) is reduced compared to the normal mode. However, in the normal mode, the air blow to the second delivery range R was about 60 seconds in 2 minutes, whereas in the dry mode, it was about 45 seconds × 2 = about 90 seconds. Therefore, the air volume per unit time (for example, 2 minutes) in the drying mode can be increased as compared with the normal mode.

  In the third embodiment, the second sending range R can be adjusted similarly to the first and second embodiments. The processing flow in the drying mode may be the same as that in the first and second embodiments. Specifically, in the heating strong wind operation state (step # 4) and the blowing strong wind operation state (step # 8) (see FIG. 7), the air is blown only in the second delivery range R in the first embodiment. As a result, in the third embodiment, air is sent to the dry delivery range, while the second delivery range R is blown to reduce the swing speed.

  Thus, in the third embodiment, in the drying mode, the louvers (louvers 24 and the like) send air to the dry sending range that includes the second sending range R and is wider than the second sending range R. When swinging in the dry swing range and sending to the second delivery range R, the variable speed is slower than when sending out of the second delivery range R. In other words, the control unit 5 delays the changing speed of the louver 24 in the second transmission range R as compared with a range other than the second transmission range R. In the dry mode, the air is blown in a wider range than the second delivery range R, but the air is intentionally blown in the second delivery range R so that the air volume per unit time is larger than that in the normal mode (see above implementation). It may be combined with Form 2). Thereby, the air volume per unit time blown to the 2nd delivery range R in which a drying object exists can be increased, and a drying object can be made easy to dry. In addition, since air is blown over a wider range than the second delivery range R, it is possible to blow away high-humidity air that evaporates from the drying target and stays around the second delivery range R, thereby making it easier to dry the drying target. .

(Fourth embodiment)
Next, the air conditioner 1 which concerns on the 4th Embodiment of this invention is demonstrated using FIG. FIG. 9 is an explanatory diagram for explaining air blowing in the drying mode in the fourth embodiment.

  The air conditioner 1 of the fourth embodiment differs from the first to third embodiments in the blowing method in the drying mode, but the processing flow in the hardware itself and in the drying mode may be the same. In view of this, parts common to the first to third embodiments are used except for the case where they are specifically described, and the description and illustration thereof are omitted.

  As shown in FIG. 9, in the third embodiment, a second delivery range R (an example of the upper limit and the lower limit of the second delivery range R is shown by a solid line in FIG. 7) is narrower than the delivery range in the normal mode. The provided points are the same as in the first to third embodiments. For example, the range of the second delivery range R is a swing width of about 40 to 45 degrees.

  However, in the present embodiment, in the dry mode, the air is blown in a range including the second delivery range R and wider than the second delivery range R (dry delivery range = R + 2R2). In the present embodiment, the dry delivery range is described as being the same range as the delivery range in the normal mode (first delivery range). In other words, even in the drying mode, the control unit 5 swings the louver 24 in the first swing range (= dry swing range) and blows air in the range of about 0 ° to about −90 ° (dry in FIG. 7). An example of the upper limit and the lower limit of the sending range is shown by a broken line).

  In the fourth embodiment, the control unit 5 swings the louver so that air is delivered to the dry delivery range (the louver operates in the first swing range). In the second delivery range R (range R in FIG. 9), the control unit 5 controls the indoor fan motor 23M to adjust the rotational speed of the indoor fan motor 23M in the normal mode or in a range R2 other than the second delivery range R. Raise than when. For example, the control unit 5 sets the rotational speed of the indoor fan motor 23M in the second delivery range R to be higher than the rotational speed of the indoor fan motor 23M in the normal mode or the maximum air volume in the range R2 other than the second delivery range R. Enlarge. Thereby, intentional concentration of the air blow to the second delivery range R is performed. Therefore, the air volume per unit time in the second delivery range R is larger than that in the normal mode when air is blown in the range of 0 degrees to about -90 degrees.

  For example, it is assumed that the swing speed (swinging speed) of the louver 24 is the same in the drying mode and the normal mode. In the normal mode, the louver 24 swings twice so as to blow into the dry delivery range (the first delivery range, the range of the swing S1) for 2 minutes (two round trips to the dry delivery range). Since the second delivery range R is included in the dry delivery range, two reciprocating blows with respect to the second delivery range R). On the other hand, in the dry mode, it is assumed that the second delivery range R is about one half of the dry delivery range. In the dry mode, the indoor fan 23 blows air with the same air volume as in the normal mode except for the second delivery range R, and blows air with 1.5 times the air volume A in the normal mode in the second delivery range R. If it does so, it can be set as a 1.5 times as much air volume (air volume 1.5A) with respect to the 2nd sending-out range R in the dry mode as compared with the normal mode. Therefore, the air volume per unit time in the drying mode can be increased as compared with the normal mode.

  In the fourth embodiment, the second sending range R can be adjusted similarly to the first to third embodiments. The processing flow in the drying mode may be the same as in the first to third embodiments. Specifically, in the heating strong wind operation state (step # 4) and the blowing strong wind operation state (step # 8) (see FIG. 7), the air is blown only in the second delivery range R in the first embodiment. As a result, in the fourth embodiment, the controller 5 controls the rotational speed of the indoor fan motor 23M in the second delivery range R as compared with the case where the control unit 5 sends air to the dry delivery range and blows air outside the second delivery range R. Make it faster.

  In this way, when the air conditioner 1 is in the drying mode, the louver (louver 24 or the like) is a dryer that sends air to a dry delivery range that includes the second delivery range R and is wider than the second delivery range R. The indoor fan swings in the swing range, and the indoor fan rotates faster than when sending out to the second delivery range R than when sending out outside the second delivery range R. In the dry mode, the air is blown in a range wider than the second delivery range R, but the air is intentionally blown in the second delivery range R so that the air volume per unit time is larger than that in the normal mode. Thereby, the air volume per unit time blown to the 2nd delivery range R in which a drying object exists can be increased, and a drying object can be made easy to dry. In addition, since air is blown over a wider range than the second delivery range R, it is possible to blow away high-humidity air that evaporates from the drying target and stays around the second delivery range R, thereby making it easier to dry the drying target. .

  In the second to fourth embodiments, the air is blown in a wider range than the second delivery range R in the drying mode, but any one or a combination of these is intentionally made to be more than the second delivery range R. The air volume per unit time to the second delivery range R may be increased over a wider range than the range other than the second delivery range R.

(Fifth embodiment)
Next, the air conditioner 1 which concerns on 5th Embodiment is demonstrated using FIG. 10, FIG. FIG. 10 is an explanatory diagram for explaining air blowing in the drying mode according to the fifth embodiment. FIG. 11 is a flowchart illustrating an example of a processing flow in the drying mode according to the fifth embodiment.

  Although the air conditioner 1 of 5th Embodiment differs from the 1st-4th embodiment in the ventilation method in dry mode, hardware itself may be the same. Therefore, the parts common to the first to fourth embodiments are used except for the case where they are specifically described, and the description and illustration are omitted.

  The moisture of the drying object D falls over time. Therefore, in the present embodiment, the upper limit of the second delivery range R is brought closer to the lower limit every time after the drying mode D is entered and the air to be dried D is blown. For this reason, the control unit 5 counts time (for example, the timing unit 53 counts time), and when a predetermined time has elapsed since the start of air blowing in the drying mode, or from the change of the upper limit position of the second delivery range R. When the predetermined time has elapsed, the control content of the louver motor 24M is changed to change the upper limit position of the second delivery range R.

  In FIG. 10, an example of the upper limit and the lower limit of the second transmission range R is indicated by a solid line. For example, in the beginning after entering the drying mode, the control unit 5 sets the upper limit position of the second delivery range R to the highest position (upper limit position P1). In the first stage, the control unit 5 swings the louver 24 with the width between the upper limit position P1 and the lower limit lower limit position P4 as the second delivery range R.

  And if predetermined time passes since the ventilation start in dry mode, the control part 5 will be made into the position (upper limit position P2) which lowered the upper limit position of the 2nd delivery range R. Accordingly, the control unit 5 swings the louver 24 with the width between the upper limit position P2 and the lower limit lower limit position P4 as the second delivery range R.

  Further, when a predetermined time has elapsed since the upper limit position P2, the control unit 5 sets the upper limit position of the second delivery range R as the upper limit position P3. Thereby, the control unit 5 swings the louver 24 with the width between the upper limit position P3 and the lower limit position P4 as the second delivery range R.

  Here, although the predetermined time can be arbitrarily determined, the predetermined time may be obtained by dividing the time for blowing air into the second delivery range R for drying by the number of stages of the second delivery range R. For example, when blowing air for 3 hours in the second delivery range R, the second delivery range R changes in three stages in the example of FIG. 10, so the predetermined time may be set to 1 hour. Further, the predetermined time may be set with a weight so that the predetermined time becomes gradually longer or gradually shortened.

  Next, the flow of processing in the drying mode in the fifth embodiment will be described with reference to FIG. FIG. 11 is a flowchart illustrating an example of a processing flow in the drying mode according to the fifth embodiment. The flowchart of the fifth embodiment is obtained by adding processing for narrowing the second sending range R to the processing flow of the first to fourth embodiments.

  Since the start to step # 24 in FIG. 11 may be the same as the start to step # 4 in the first embodiment, description thereof will be omitted (see FIG. 6). When the heating and strong wind operation is started in the heating operation (step # 24), the control unit 5 determines whether the first predetermined time has elapsed since the start of the drying mode or after the second delivery range R was first narrowed. Confirmation (step # 25). In the air conditioner 1 of the present embodiment, the predetermined time in the heating operation and the operation other than heating (cooling and dehumidification) is different, and therefore the predetermined time in the heating operation is referred to as a first predetermined time for convenience.

  If the first predetermined time has not elapsed (No in step # 25), the flow returns to step # 24. On the other hand, if the first predetermined time has elapsed (Yes in step # 25), the control unit 5 lowers the upper limit position of the second transmission range R by a predetermined angle and changes the second transmission range R (step #). 26). Thereby, in the subsequent blowing, the downward blowing in the second delivery range R is focused. Then, the process proceeds to step # 27. Steps # 27 to # 30 may be the same as steps # 5 to # 8 in the first embodiment, and the description thereof is omitted (see FIG. 6).

  On the other hand, if the blowing high wind operation is started during the operation other than heating (step # 30), the control unit 5 starts the drying mode or first narrows the second delivery range R and then the second predetermined time. It is confirmed whether the time has elapsed (step # 31). In the air conditioner 1 of the present embodiment, since the air blowing time to the drying object D is shorter in the operation other than heating (cooling and dehumidification) than in the heating operation, the second predetermined time is shorter than the first predetermined time. Can be shortened.

  If the second predetermined time has not elapsed (No in step # 31), the flow returns to step # 30. On the other hand, if the second predetermined time has elapsed (Yes in step # 31), the controller 5 lowers the upper limit position of the second transmission range R by a predetermined angle and changes the second transmission range R (step #). 32). Thereby, in the subsequent blowing, the downward blowing in the second delivery range R is focused. Then, the process proceeds to step # 33. Steps # 33 to # 35 may be the same as steps # 9 to # 11 of the first embodiment, and thus description thereof is omitted (see FIG. 6).

  In addition, 5th Embodiment can be implemented with either the 1st-4th embodiment mentioned above, or a combination. In other words, in any embodiment, the controller 5 gradually changes the swing width of the louver 24 so that the upper limit of the second delivery range R approaches the lower limit when operating in the dry mode.

  In this way, in the air conditioner 1, the louver 24 varies the wind direction in the vertical direction, and gradually lowers the upper limit position of the second swing range in the drying mode. When the moisture of the drying target is dried, it is transmitted downward and it is difficult to dry the lower part, so that the air volume per unit time downward of the drying target can be increased. Therefore, the entire drying object can be quickly dried.

(Sixth embodiment)
Next, the air conditioner 1 which concerns on the 6th Embodiment of this invention is demonstrated using FIG. FIG. 12 is an explanatory diagram for explaining air blowing in the drying mode in the sixth embodiment.

  The air conditioner 1 of the sixth embodiment is different from the first to fifth embodiments in that the second delivery range R is narrower in the left and right directions than in the normal mode in the drying mode. The flow may be similar. Therefore, the parts common to the first to fifth embodiments are used except for the case where they are specifically described, and the description and illustration are omitted.

  FIG. 12 is an overhead view of the room from above, unlike the above-described drawings. In FIG. 12, an example of the transmission range in the normal mode is shown by a broken line. In FIG. 12, an example of the left limit and the right limit of the second transmission range R of the second transmission range R in the sixth embodiment is illustrated by a solid line.

  In the first to fifth embodiments, the second delivery range R has a narrower blowing width (blowing angle) in the vertical direction than in the normal mode. And in 6th Embodiment, the air volume of the unit time to the 2nd sending range R is increased rather than a normal mode by intentionally narrowing the 2nd sending range R also in the left-right direction. Specifically, when the drying mode is selected, the control unit 5 controls the left and right louver motor 25M, makes the swing width of the left and right louvers 25 narrower than the normal mode, and controls the blowing in the left and right direction.

  As described above, the second transmission range R may be a range narrowed only in the vertical direction in the transmission range in the normal mode or the like. In addition, a range narrowed only in the left-right direction in the transmission range in the normal mode or the like may be set as the second transmission range R. Alternatively, the second transmission range R may be a range narrowed in the vertical direction and the horizontal direction in the transmission range in the normal mode or the like.

  In this way, the louver motor 24M that moves the louver 24 that defines the delivery range in the vertical direction and the louver motor 24M (left and right louver motor 25M) that moves the louver 24 (left and right louver 25) that defines the delivery range in the left-right direction are provided. The control unit 5 causes the air to be blown in the drying mode with the second delivery range R as a narrow range in the up and down direction and / or the left and right direction with respect to the entire range capable of blowing. Thereby, the 2nd sending range R can be defined finely. Therefore, the second delivery range R can be determined corresponding to the length in the vertical direction and the length in the horizontal direction of the drying object D.

  Another embodiment will be described. In the above embodiment, the example of the air conditioner 1 that blows air from the outlet 21 in the range from the horizontal direction (0 degree) to the substantially vertical downward direction (about -90 degrees) in the vertical direction has been described. However, the air blowing angle is not limited to the above example. For example, the air conditioner 1 may be able to blow out air above the horizontal (for example, enable air to be sent 20 degrees to 30 degrees above the horizontal direction).

  In the above embodiment, the example in which the dry delivery range is the same range as the delivery range in the normal mode (first delivery range) has been described. However, the dry delivery range may be wider or narrower than the first delivery range, and may not be the same range.

  In the dry mode, the second delivery range R has been described as being about one-half of the dry delivery range (first delivery range), but if it is narrower than the dry delivery range (first delivery range), A range wider than about one half (for example, a width (range) of about 1/2, about 60 degrees) may be used, or a range narrower than about one half (for example, about one third, about A width (range) of 30 degrees may be used.

  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.

  The present invention can be used for an air conditioner.

In the above air conditioner, it is preferable to have a setting unit that accepts an operation setting of the air conditioner and includes a button used for setting the wind direction in the normal mode .

  In the above air conditioner, it is also preferable that the setting unit accepts an operation of changing the second delivery range using the button in the drying mode. Moreover, it is also preferable that the setting unit accepts an operation of changing the end of the second delivery range using the button in the drying mode.

According to these configurations, the setting unit receives an operation (setting instruction) for determining the second transmission range. Thereby, the range which swings a louver can be set, and the 2nd sending range can be matched with the range in which drying object exists. Therefore, it is possible to eliminate the blowing to a range where there is no drying target and efficiently blow and dry the entire drying target. According to these configurations, the setting unit accepts an input for changing the end of the second transmission range (determining the end position). Thereby, the second transmission range can be set finely.

The air conditioner includes a heat exchanger for dehumidifying the air, and when the drying mode is in the drying mode, the air outlet is connected to the heat exchanger when a predetermined time elapses from the start of the drying operation. The dehumidified air is sent out, and the louver fixes the blowing direction in the horizontal direction.
