<Overall>
Drawing 1 is a figure showing the appearance composition of the air harmony machine concerning an embodiment. The air conditioner AC is a device that performs indoor air conditioning such as cooling and heating using, for example, heat pump technology. The air conditioner AC is roughly classified into an indoor unit 100 installed on an indoor wall, ceiling, floor, and the like, an outdoor unit 200 installed outdoors, and the like, and communicates with the indoor unit by infrared rays, radio waves, communication lines, and the like. The remote controller 40 (air conditioning control terminal) for the user to operate the air conditioner AC and the sensor unit 50 for obtaining information used for controlling or displaying the air conditioner AC such as room temperature and outside temperature (see FIG. 4). ). Moreover, the indoor unit 100 and the outdoor unit 200 are connected with refrigerant | coolant piping and the communication cable. In the indoor unit 100, a surface temperature detection unit 123 is disposed at the center in the left-right direction. The remote control transmission / reception unit Q is arranged at a position where it is easy to receive a remote control signal in the vicinity of the front lower part of the indoor unit 100.

  The remote controller 40 is operated by the user and transmits an infrared signal to the remote controller transmission / reception unit Q of the indoor unit 100. The contents of the infrared signal are commands such as an operation request, a change in set temperature, a timer, an operation mode change stop request, and a clothes drying operation request. The air conditioner AC performs air conditioning operations such as a cooling mode, a heating mode, a dehumidifying mode, and a clothes drying operation (laundry dehumidifying operation) based on the commands of these infrared signals. In addition, the indoor unit 100 transmits data such as room temperature information, humidity information, and information on electricity bill information from the remote control transmission / reception unit Q to the remote control 40.

  The clothes drying operation is basically an operation of drying laundry clothes in a short time by combining heating operation and dehumidifying operation.

<Indoor unit>
FIG. 2 is a diagram illustrating a side cross-sectional configuration of the indoor unit according to the embodiment. The indoor unit 100 includes an indoor heat exchanger 102, a blower fan 103, left and right wind direction plates 104, vertical wind direction plates 105 (upper vertical wind direction plates 105a and lower vertical wind direction plates 105b), a front panel 106, electrical components, various sensors, and the like. In the housing 101. The indoor heat exchanger 102 has a plurality of heat transfer tubes, heats the indoor air taken into the indoor unit by the blower fan 103 with the refrigerant flowing through the heat transfer tubes, and cools, heats, etc. the air. It is configured as follows. The heat transfer pipe communicates with the refrigerant pipe described above and constitutes a part of a known refrigerant cycle. The blower fan 103 can adjust the wind speed.

  The left and right wind direction plates 104 are rotated forward and backward by a motor for the left and right wind direction plates 104 with the base end side as a fulcrum about a rotation shaft provided at the lower part of the indoor unit 100. And the front end side of the left and right wind direction plate 104 faces the indoor side, so that the front end side of the left and right wind direction plate 104 can operate in a horizontal direction. The up-and-down wind direction plate 105 is rotated forward and backward by a motor for the up-and-down wind direction plate 105 with rotation shafts provided at both ends in the longitudinal direction of the indoor unit 100 as fulcrums. Thereby, the front end side of the up-and-down wind direction board 105 can be operated so as to swing in the up-and-down direction. The front panel 106 is installed so as to cover the front surface of the indoor unit 100, and can be rotated forward and backward by a motor for the front panel 106 with the rotation axis at the lower end as a fulcrum. Incidentally, the front panel 106 may be fixed to the lower end of the indoor unit without rotating.

  The indoor unit 100 takes in indoor air into the indoor unit through the air inlet 107 and a filter (not shown) as the blower fan 103 rotates, and heat-exchanges the air in the indoor heat exchanger 102. . Thereby, the air after the heat exchange is cooled by the indoor heat exchanger 102 or heated. The air after the heat exchange is guided to the blowout air passage 109a. Further, the air guided to the blowout air passage 109a is sent out from the air blowout port 109b to the outside of the indoor unit, and air is conditioned in the room. When the air after the heat exchange is blown into the room from the outlet, the horizontal wind direction is adjusted by the left and right wind direction plates 104, and the vertical wind direction is adjusted by the upper and lower wind direction plates 105.

<Outdoor unit>
The outdoor unit 200 (see FIG. 1) divides (divides) the heat exchanger room and the machine room by a partition plate, an electrical component box, and a lead wire support component. In the heat exchanger chamber, a propeller fan 207 (see FIG. 4) that promotes heat exchange with the outside air of the refrigerant circulating in the refrigerant pipe, a motor for driving the propeller fan, a propeller fan support that rotatably supports the propeller fan 207, In addition, an outdoor heat exchanger 215 (FIG. 3) for exchanging heat between the outside air and the circulating refrigerant is disposed. The machine room includes a compressor 211 (see FIG. 3) that converts the circulating refrigerant into a high-temperature and high-pressure gas refrigerant, an electric expansion valve that converts room-temperature and high-pressure liquid refrigerant into low-temperature and low-pressure liquid refrigerant, a reactor for electrical components, and A heat transfer pipe of a refrigerant pipe through which the refrigerant flows is provided. The electrical component box stores electrical components for controlling the outdoor unit, and an electrical component lid is covered on the electrical component box.

  FIG. 3 is a diagram illustrating a refrigeration cycle system of the air conditioner according to the present embodiment. The indoor heat exchanger 102 built in the indoor unit 100 includes a dehumidifying throttle mechanism 114 in the middle, and the indoor heat exchanger 102a on the front side (lower side in FIG. 3) of the dehumidifying throttle mechanism 114 (rear side) The indoor heat exchanger on the upper side in FIG. The outdoor unit 200 includes a compressor 211, a cooling / heating switching valve 212 (four-way valve), an outdoor heat exchanger 215, and an outdoor throttle mechanism 218.

  During the cooling operation, the high-temperature refrigerant discharged from the compressor 211 is used for cooling / heating switching valve 212, outdoor heat exchanger 215, outdoor throttle mechanism 218, indoor heat exchanger 102a, dehumidifying throttle mechanism 114, indoor heat exchanger 102b, cooling / heating switching valve. It is made to circulate in the order of 212 (solid arrow) and is sucked into the compressor 211. In a general cooling operation, the outdoor throttle mechanism 218 is throttled and the indoor throttle mechanism 114 is fully opened, thereby cooling both the indoor heat exchangers 102a and 102b and exchanging heat, thereby blowing out cool air from the indoor unit 20.

  During the heating operation, the high-temperature refrigerant discharged from the compressor 211 is a cooling / heating switching valve 212, the indoor heat exchanger 102b, the dehumidifying throttle mechanism 114, the indoor heat exchanger 102a, the outdoor throttle mechanism 218, the outdoor heat exchanger 215, and the cooling / heating switching valve. It is made to circulate in order of 12 (broken arrow), and is sucked into the compressor 11. In a general heating operation, the outdoor throttle mechanism 218 is throttled and the indoor throttle mechanism 114 is fully opened, so that both the indoor heat exchangers 102a and 102b are heated and exchanged heat to blow warm air from the indoor unit 100. .

  During reheat dehumidification, the indoor heat exchanger 102a is heated by circulating the heat medium in the direction of the solid line arrow in the same manner as in the cooling operation, bringing the outdoor throttle mechanism 218 close to full open, and narrowing the dehumidification throttle mechanism 114. The indoor heat exchanger 102b is in a cooled state, and the amount of heat exchange is adjusted to dehumidify the indoor heat exchanger 23b without cooling the air blown from the indoor unit.

  In the clothes drying operation, a high air volume dehumidifying operation in which the airflow reaches a wide range and the drying capacity is high is particularly necessary. Furthermore, at the time of reheat dehumidification, it is possible to perform a cooling, isothermal or heating operation according to the room temperature. In the clothes drying operation, efficient dehumidification is performed by combining the heating mode and the dehumidification mode.In this embodiment, the heating mode dehumidification operation is used as the heating mode and the isothermal mode dehumidification operation is used as the dehumidification mode. I will explain. In the following operation modes, the heating mode may be the operation mode during the heating operation.

<Configuration of control unit of air conditioner>
Drawing 4 is a figure showing the composition of the control part of the air harmony machine concerning an embodiment. The sensor unit 50 is provided in the indoor unit 100 and the outdoor unit 200. The sensor unit 50 includes a room temperature sensor 121 (indoor temperature detection unit), a humidity sensor 122 (humidity detection unit), a clock, an outside air temperature sensor 224 (outdoor temperature detection unit), a compression temperature sensor, a refrigerant pipe temperature sensor, and the like. .

<Control unit>
The control unit 60 includes an air conditioning control unit 61, a storage unit 69, and the like when a clothing drying operation is instructed. The control unit 60 is provided in the electrical component (in the electrical component box), and based on information from the remote controller 40 (see FIG. 1) and the sensor unit 50 via the transmission / reception unit 45, the blower fan 103 of the indoor unit 100, The left / right wind direction plate 104, the up / down wind direction plate 105, and the like are controlled. The control unit 60 controls the compressor 202, the propeller fan 207, and the like of the outdoor unit 200.

  The storage unit 69 includes, for example, a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. Then, the program stored in the ROM is read out by a CPU (Central Processing Unit) of the control unit 60, developed in the RAM, and executed.

  With the above-described configuration, the control unit 60 controls the operation of the air conditioner AC according to command signals input from the remote controller 40 and sensor outputs input from various sensors, thereby performing detailed operation. Control is possible.

  FIG. 5 is a flowchart showing processing during clothes drying operation. When receiving the clothes drying operation signal (step S31), the air conditioning controller 61 reads the room temperature of the room temperature sensor 121 (step S32), and calculates the set temperature based on the value (step S33). Specifically, the set temperature is, for example, + 4 ° C. with respect to the room temperature.

  Next, the air conditioning control unit 61 reads the outside air temperature of the outside air temperature sensor 224 (step S34), and determines whether or not the outside air temperature is higher than a threshold value (step S35). That is, in step S35, the operation mode to be performed at the beginning of the clothes drying operation is determined based on the outside air temperature.

  That is, when the outside air temperature is larger than a certain threshold (step S35, high), for example, when a certain threshold is 20 ° C., if the outside air temperature is higher than 20 ° C., clothes are dried by dehumidifying operation with a large heat load. If so, it is determined that the room temperature does not decrease so as to hinder clothes drying, and the operation is performed in the dehumidifying mode (step S41). The operation time is determined while continuing the dehumidification mode (step S42), and when the preset clothes drying operation time has elapsed (step S42, Yes), the operation is automatically stopped. On the other hand, when the preset clothes drying operation time has not elapsed (step S42, No), the process returns to step S42.

  Further, when the outside air temperature in step S34 is lower than the threshold (step S35, low), for example, when the outside air temperature is 20 ° C. or lower, it is determined that the drying in the dehumidifying mode causes the room temperature to drop and hinder clothing drying. Then, the heating mode is executed (step S53).

  The operation time is determined while continuing the heating mode in step S53 (step S54), and when the preset clothes drying operation time has elapsed (step S54, elapse), the operation is automatically stopped. If the preset clothes drying operation time has not elapsed (step S54, not elapsed), it is determined whether or not the preset heating mode operation time (minimum heating operation time) has elapsed (step S54). S55) When the heating mode operation time has not elapsed (step S55, not elapsed), the heating mode is continued. When the heating mode operation time has elapsed (step S55, elapse), the indoor humidity of the humidity sensor 122 is read (step S56), and it is determined whether or not it is lower than a preset threshold value (step S57). When the indoor humidity is lower than the threshold (step S57, low), for example, when a certain threshold is 50%, the heating mode is continued when the indoor humidity is lower than 50% (step S57, low). When the room humidity is 50% or higher (step S57, high), the room temperature of the room temperature sensor 121 is read (step S58), and it is determined whether or not it is lower than the set temperature (step S59). When the temperature is equal to or lower than the set temperature (step S59, low), the heating mode is continued. When the temperature is higher than the set temperature (step S59, high), the mode is switched to the dehumidifying mode and the dehumidifying operation is executed (step S61).

  The operation time is determined while continuing the dehumidification mode in step S61 (step S62), and when the preset clothes drying operation time has elapsed (step S62, elapse), the operation is automatically stopped. When the preset clothes drying operation time has not elapsed (step S62, not yet elapsed), it is determined whether or not the preset dehumidification mode operation time has elapsed since the start of the dehumidification mode. However, when the dehumidifying mode operation time has not elapsed (step S63, not elapsed), the dehumidifying mode is continued. When the dehumidifying mode operation time has elapsed (step S63, elapsed), the indoor humidity of the humidity sensor 122 is read (step S64), and it is determined whether the humidity is lower than a preset threshold value (step S65). When the indoor humidity is lower than the threshold, for example, when a certain threshold is 50% here, the indoor humidity is lower than 50% (step S65, low), and the mode is switched to the heating mode. If the indoor humidity is equal to or higher than the threshold (step S65, high), the dehumidifying mode is continued.

  In addition, FIG. 5 shows as an example of the process at the time of clothing drying operation, and is not limited to this. For example, if the outside air temperature is larger than a certain threshold value in step S35 (step S35, high), the process may proceed to step S61. Thereby, the operation in the dehumidification mode is started first, and when the indoor humidity becomes low (step S65, low), the operation in the heating mode can be started. Moreover, although the clothes drying operation time of step S42, S54, S62 was demonstrated as the same, you may make it differ.

  FIG. 6 is a diagram illustrating an example of behavior in an operation mode during clothes drying operation. Here, an example in which the operation is started in the heating mode when the outside air temperature of the outside air temperature sensor 224 is equal to or lower than a certain threshold value is shown. The air conditioning control unit 61 first starts the operation in the heating mode, switches to the dehumidifying mode when the room temperature is high and the room humidity is high, and ends the clothes drying operation. Assuming that the heating mode operation time Ta and the dehumidification mode operation time Tb are used, the automatic operation is stopped when the time (Ta + Tb) obtained by adding the operation time of each operation mode has passed the preset clothing drying operation time.

Next, the swing range of the wind direction plate during the clothes drying operation will be described.
FIG. 13 is a diagram illustrating a state of clothes hung on the indoor clothesline. Usually, an indoor clothesline is placed under the front surface of the indoor unit 100, and clothes for laundry are hung on the clothesline. In such a situation, the swing range for each operation mode during clothes drying operation will be described with reference to FIGS.

<Wind direction range>
FIG. 7 is a diagram illustrating an example of a swing range of the heating mode and the dehumidifying mode during clothes drying operation, where (a) is a side view and (b) is a top view. Conventionally, when the clothes drying operation is performed, the wind direction is not changed between the heating mode and the dehumidifying mode. On the other hand, in the present embodiment, as shown in the side view of FIG. 7A, the swing range of the up-and-down wind direction plate 105 is the swing range a (second swing range) in the heating mode, and dehumidification is performed. In the mode, the swing range is b (a <b) (first swing range). Further, as shown in the top view of FIG. 7B, the swing range of the left and right wind direction plates 104 is the swing range a in the heating mode, and the swing range b (a <b) in the dehumidifying mode. To do.

  This is because, in order to dry clothes more efficiently, in the heating mode in which the temperature of the blown air is high, the vertical wind direction plate 105 and the left and right wind direction plates 104 are controlled so that the wind direction hits the clothes. On the other hand, in the dehumidifying mode for condensing the moisture in the indoor air, the purpose is to circulate the air with reduced humidity in the room, and the vertical wind direction plate 105 The left and right wind direction plates 104 are controlled.

<Air volume>
FIG. 8 is a diagram illustrating an example of the air volume during clothes drying operation, where (a) is in the heating mode and (b) is in the dehumidifying mode. In the case of the dehumidifying mode shown in FIG. 8B, by setting the wind direction to be in a wide range, the air volume hitting the clothing is reduced as a result. For this reason, even if it is a case of dehumidification mode, it is unpreferable to reduce the air volume which blows wind on clothing. For this reason, it is good to increase the air volume 82 in the dehumidification mode of FIG.8 (b) with respect to the air volume 81 in the heating mode shown to Fig.8 (a). Specifically, in the dehumidifying mode, the rotational speed of the blower fan 103 is increased. Thus, by increasing the overall air volume, it is possible to prevent a decrease in the air volume hitting the clothing.

<Comparison with other than clothes drying operation>
FIG. 9 is a diagram illustrating an example of a swing range in the dehumidifying mode, where (a) is a swing range during normal operation, and (b) is a swing range during clothing drying operation. If the swinging range in the dehumidifying mode during normal operation shown in FIG. 9A is the swinging range bn (third swinging range), the swinging range in the dehumidifying mode during clothing drying operation is as shown in FIG. As shown in FIG. 9 (b), the relationship is preferably a <b <bn. The swing range a shown in FIG. 9B is the same as the swing range a shown in FIG.

  That is, in the dehumidifying mode, the swing range of the up / down wind direction plate 105 and the left / right wind direction plate 104 is widened, but the swing range is preferably narrower than the operation range other than the clothing drying mode. By making the wide swing range narrower than the swing range other than during the clothes drying operation, it is possible to increase the amount of air hitting the clothes as compared to when operating in the swing range other than during the clothes drying operation. .

<Modification in dehumidification mode>
FIG. 10 is a diagram illustrating an example in which the swing range in the dehumidifying mode during clothing drying operation is changed. FIG. 10A illustrates a period A (first period), and FIG. 10B illustrates a period B (second In the case of In the case of the dehumidifying mode in FIG. 7A, the swing range b has been described, but the present invention is not limited to this. In FIG. 10, the dehumidifying mode may be divided into two periods, that is, period A (first period) and period B (second period), and the swing range may be changed in each period. . In the dehumidifying mode, the user may be distrusted by the long moment that the up / down wind direction plate 105 and the left / right wind direction plate 104 are facing the portion other than clothing. Some people may find it more efficient to use the wind direction towards clothing in all driving modes.

  For this reason, the operation time in the dehumidifying mode is repeated in order of period A, period B, period A, period B, and the swing range in period A is the swing range b shown in FIG. The swing range in period B is the same as the swing range a shown in FIG. For example, at half the operating time in the dehumidifying mode (for example, the period A and the period B are set to the same operating time, and the period A is set every 5 minutes), the vertical wind direction plate 105 and the left and right wind direction plate 104 are heated. Control in the same direction as the mode. By doing so, it is possible to increase the time suitable for clothing and reduce user distrust.

<Cooling mode during clothes drying operation>
FIG. 11 is a diagram illustrating an example of the swing range of the heating mode and the cooling mode during clothes drying operation. Depending on the outdoor air temperature and humidity, when the clothes drying operation is performed in the dehumidifying mode and the heating mode in the control shown in FIGS. 7 to 10, the time for generating the heating mode is shortened, and the time for applying the wind direction to the clothes is shortened. The air volume hitting clothing may be reduced.

  In the case of FIG. 11, unlike the case where the clothes drying operation is performed in the dehumidifying mode and the heating mode, the clothes drying mode is performed in the cooling mode and the heating mode. At this time, the swing range of the vertical airflow direction plate 105 is set to a swing range a in the heating mode and a swing range c (a <c) in the cooling mode. In the air conditioning mode, the air blown from the air conditioner AC is cool air. Therefore, especially in a situation where there are few people in the room and there is little movement, the room temperature gradually decreases as the operation continues. It is possible to condense the water vapor in the room by being cooled by 102 and discharge it as the drain to the outside. As a result, when the room temperature is lowered, the time during which the heating mode is generated becomes longer, and as a result, it is possible to increase the air volume hitting the clothing.

<Modification of FIG. 7>
FIG. 12 is a diagram illustrating another example of the swing range of the heating mode and the dehumidifying mode during the clothes drying operation. When the moisture contained in the clothing is vaporized, it is taken into the surrounding air. The air that has taken in the vaporized water becomes relatively light and moves upward. However, the case where the temperature of the ceiling, walls and furniture is low and condenses again is excluded. In the dehumidifying mode, there is a problem that it cannot be said that dehumidification is most efficiently performed when the wind direction is directed to a wide range.

  In the dehumidifying mode shown in FIG. 12, the swing range is b3. The wind direction in the dehumidifying mode is a wind direction having a wide swing range (swing width) above the air direction in the heating mode. As a result, by directing the wind direction on the clothing in the heating mode, it is thought that the air above the room, which is considered to contain more water vaporized from the clothing, is efficiently blown in the dehumidification mode, There is an effect that moisture can be discharged outside the room.

  In the present embodiment, in FIGS. 7 to 10 and 12, the first swing range is described in the dehumidifying mode, and the second swing range is described in the heating mode. However, the present embodiment is not limited to this. . For example, in the dehumidifying mode, the wind direction range a may be set, and in the heating mode, the wind direction range b may be set.

<Other scope>
In the present embodiment, the air conditioner having no clothing detection unit has been described. However, even in an air conditioner having a clothing detection unit, a clothing drying detection unit, and the like, in the dehumidification mode, the first wind direction plate is determined in advance. In the heating mode, it is possible to apply air by swinging the second swing range that is narrower than the first swing range. The clothing detection unit uses a surface temperature detection unit, and specifically includes a non-contact temperature sensor such as a thermopile.

  The air conditioner includes an indoor temperature detection unit (for example, a room temperature sensor) that detects a room temperature, and a humidity detection unit (for example, a humidity sensor) that detects the relative humidity in the room, and a clothing detection unit The relative humidity of the area is estimated from the room temperature, the relative humidity detected by the humidity detection unit, and the surface temperature of the area detected by the surface temperature detection unit, and dried in the room according to the estimated relative humidity. An area of clothing that is worn may be detected.
