Description

  The present invention relates to an air conditioner remote control device that performs an operation of an air conditioner main body having a plurality of air outlets.

  When a conventional air conditioner is selected for a cooling operation, a heating operation, or the like, the air conditioner is operated with a setting that optimizes the air blowing direction (air flow direction) according to the operation content. For example, at the time of cooling operation of the air conditioner, cold air having a specific gravity higher than that of room air is blown out. Therefore, the air is circulated throughout the room with the blowing direction upward. Further, during the heating operation of the air conditioner, warm air having a specific gravity lower than that of the room air is blown out, so that the warm air is circulated throughout the room with the blowing direction downward. Thus, when changing the airflow direction according to the operation content, if there is only one air outlet, the user can easily display the vertical direction of the airflow by displaying the indoor unit sideways on the display unit of the remote controller. I can understand.

  Some recent air conditioners have a plurality of air outlets, and finer airflow control is possible. In this type of air conditioner, the airflow to be blown out is composed of a plurality of partial airflows, and the vertical airflow direction control plate and the left and right airflow direction control plates are independent from each other on the left and right, so the airflow of the conditioned air that is blown out is The left and right independent partial air currents are blown out (see, for example, Patent Document 1).

JP 2012-42138 A

  However, in the air conditioner shown in Patent Document 1, two left and right independent partial airflows are blown out, and the state of this airflow is displayed in a plane on the display unit of the remote control device operated by the user. Even if the wind direction in the direction can be grasped, it is difficult to grasp the wind direction in the vertical direction due to poor visibility.

  Furthermore, when the number of air outlets is larger than that of Patent Document 1, fans are arranged for each air outlet, and the air direction and the air volume are different from each other, the state of the air current is improved with only a planar air current display. It is difficult to grasp.

  In particular, in recent air conditioners, a so-called “automatic setting mode” that automatically sets the air blowing direction (airflow direction) and the air volume suitable for a specific operation mode such as cooling operation or heating operation has become widespread. It's getting on. Among them, the air flow that can be operated by the user and the air flow that cannot be operated during the “automatic setting mode” among the plurality of air flows so that the comfort is not lost depending on the adjustment of the wind direction or the air volume, and the distinction is made. There was nothing that could be displayed with good visibility.

  The present invention has been made in view of the above, and when operating an air conditioner main body that blows out airflow from a plurality of outlets, it is possible to easily distinguish between airflow that can be operated by the user and airflow that cannot be operated by the user. An object of the present invention is to provide a remote control device for an air conditioner.

  In order to achieve the above-described object, the air conditioner remote control device according to the present invention includes a blower fan and an air outlet individually disposed at the center and the left and right of the indoor unit main body, and the air volume of the air flow blown from each air outlet. And an air conditioner remote controller for operating the air conditioner main body capable of individually adjusting the wind direction, a display unit for displaying an operation operation screen, and the indoor unit and the air outlets on the display unit A control unit that controls to display an image of the airflow direction to be blown off viewed obliquely from the lateral direction, and the air conditioner outputs the airflow blown out from a specific air outlet among the airflows to be blown out from the air outlets. When the operation from the remote control device is disabled, the control unit can distinguish between the airflow that can be operated from the remote control device and the airflow that cannot be operated from among the airflows blown out from the respective outlets. And wherein the Shimesuru.

  In the air conditioner remote control device of the present invention, when operating the air conditioner body, an automatic setting mode for automatically setting a predetermined wind direction and air volume suitable for each operation mode is selected in a specific operation mode. An operation key unit, and when the automatic setting mode is selected by the operation key unit during operation in the specific operation mode, the control unit is adapted to the airflow blown from each of the outlets to the operation mode The airflow direction and the airflow amount are set, and the airflow that can be operated from the remote control device and the airflow that cannot be operated are displayed.

  According to the air conditioner remote control device of the present invention, the control unit of the remote control device for operating the indoor unit of the air conditioner sees the airflow direction blown from the indoor unit and each outlet on the display unit from an oblique lateral direction. Suitable for a specific operation mode, because it is controlled to display an image, and the airflow that can be operated by the user and the airflow that cannot be operated among the airflows blown out from each outlet are displayed on the display unit so that they can be distinguished. The airflow direction and airflow are automatically set, and the airflow that can be operated and the airflow that cannot be operated among the airflows blown out from multiple outlets so that the airflow suitable for the operation mode is not lost depending on the adjustment of the airflow direction or airflow. This provides an effect that the distinction can be easily recognized.

FIG. 4B is a plan view illustrating a detailed setting key of the remote control device of the air conditioner of FIG. 4A.

  As shown in FIG. 1, the indoor unit 20 of the air conditioner used in the present embodiment includes a main unit 263 and a left fan unit 261 and a right fan unit 262 on both sides thereof. The main unit 263 of the indoor unit 20 includes a main housing 27. In the main housing 27, the exterior panel 29 covers the housing body 28. A central outlet 30 is formed in the housing body 28. A suction port (not shown) is formed in the upper part of the exterior panel 29. The central outlet 30 opens downward. Such a housing body 28 can be fixed to, for example, an indoor wall surface. In that case, as for the central blower outlet 30, the front end 30a is arrange | positioned in the upper position compared with the rear end 30b. As a result, the central outlet 30 is formed in a front-up posture at a predetermined inclination angle α. With such an action of the inclination angle α, the airflow can be blown not only downward from the central blower outlet 30 toward the floor surface but also in parallel (horizontal direction) to the floor surface.

  A pair of front and rear wind direction plates 31 a and 31 b are arranged at the central outlet 30. The up-and-down wind direction plates 31a and 31b can rotate around the horizontal axes 32a and 32b, respectively. These horizontal axes 32a and 32b may be set at the rear ends of the up and down wind direction plates 31a and 31b. Depending on the rotation, the vertical airflow direction plates 31a and 31b can open and close the central outlet 30.

  A left fan unit 261 and a right fan unit 262 are individually installed on both side surfaces of the housing body 28. That is, the left fan unit 261 and the right fan unit 262 are disposed outside the side wall of the housing body 28. The left fan unit 261 includes a left side fan housing 331 and a left outlet 341 is formed. The right fan unit 262 includes a right side fan housing 332, and a right air outlet 342 is formed. The left outlet 341 and the right outlet 342 can be rotated around the horizontal axis 35 by a driving mechanism (not shown). The horizontal axis lines 32a and 32b and the horizontal axis line 35 extend in parallel with each other as shown in FIG. The side panel 36 covers the side surfaces of the housing 331 and the housing 332. A side suction port 37 is formed in the side panel 36. As shown in FIG. 1, the side suction port 37 is formed by, for example, collecting a plurality of small openings.

  The air conditioner according to the present embodiment includes a remote control device 10 that can perform a driving operation remotely from the above-described indoor unit 20 by wireless two-way communication.

  The indoor unit and outdoor unit of the air conditioner according to the present embodiment are configured as shown in FIG. An indoor heat exchanger 264 and a central blower fan 265 are incorporated in the main unit 263 of the indoor unit 20 described above. The central blower fan 265 generates an air flow according to the rotation of the cross flow fan. The indoor air is sucked into the main unit 263 by the action of the central blower fan 265, and passes through after exchanging heat with the refrigerant in the indoor heat exchanger 264. The cold or warm airflow after passing through the indoor heat exchanger 264 is blown out from the central outlet 30 of the main unit 263. Further, the flow rate of the airflow passing through the indoor heat exchanger 264 is adjusted according to the number of revolutions per minute of the cross flow fan. In the indoor heat exchanger 264, the amount of heat energy exchanged between the refrigerant and the air can be adjusted according to the flow rate of the airflow.

  As shown in FIG. 2, the refrigeration circuit 41 of the outdoor unit 40 includes a four-way valve 42, a compressor 43, an outdoor heat exchanger 44, an expansion valve 45, an outdoor fan 46, a refrigerant pipe 50, and the like. For example, when the cooling operation is set in the refrigeration circuit 41, the four-way valve 42 connects the second port 42b and the third port 42c to each other, and connects the first port 42a and the fourth port 42d to each other. Thereby, the high-temperature and high-pressure refrigerant is supplied to the outdoor heat exchanger 44 from the discharge pipe 43 b of the compressor 43. The refrigerant flows through the outdoor heat exchanger 44, the expansion valve 45, and the indoor heat exchanger 264 in order. In the outdoor heat exchanger 44, the heat energy of the refrigerant is released to the outside air. The refrigerant is decompressed to a low pressure by the expansion valve 45 and absorbs heat from the surrounding air in the indoor heat exchanger 264. The cold air thus generated is caused to flow into the indoor space by the action of the central blower fan 265. The refrigerant that has absorbed heat by the indoor heat exchanger 264 is returned to the compressor 43 via the four-way valve 42.

  When the heating operation is set in the refrigeration circuit 41, the four-way valve 42 connects the second port 42b and the fourth port 42d to each other, and connects the first port 42a and the third port 42c to each other. Thereby, the high-temperature and high-pressure refrigerant is supplied from the discharge pipe 43 a of the compressor 43 to the indoor heat exchanger 264. The refrigerant flows through the indoor heat exchanger 264, the expansion valve 45, and the outdoor heat exchanger 44 in order. In the indoor heat exchanger 264, the heat energy of the refrigerant is released to the surrounding air, and warm air is generated. Warm air is caused to flow into the indoor space by the function of the central blower fan 265. The refrigerant is decompressed to a low pressure by the expansion valve 45 and absorbs heat from the surrounding air in the outdoor heat exchanger 44. Thereafter, the refrigerant is returned to the compressor 43.

  As described above, the left fan unit 261 and the right fan unit 262 of the air conditioner according to the present embodiment are provided independently of the main body unit 263 and each includes the fan and the air outlet. It is possible to individually control the direction and volume of air blown from the air. The air blown out from the central outlet 30 is a cold or warm air stream passing through the heat exchanger 264, and the air blown out from the left outlet 341 and the right outlet 342 blows out the sucked room air as it is. Airflow.

  In the case of the cooling operation, the cool air having a high specific gravity blown out from the central outlet 30 is blown upward, and the airflow from the left outlet 341 and the right outlet 342 is warmer than the airflow from the central outlet 30. By blowing out downward from the direction blown out from the blower outlet 30, the cold air can be lifted from below and spread widely near the ceiling, allowing the cold air to circulate evenly in the room, and depending on the direction of the wind, Play the role of hitting. FIG. 7 shows the airflow blown out from each outlet in this case by the display unit of the remote control device.

  Further, in the heating operation, it is the reverse of the cooling operation, and warm air with a low specific gravity blown out from the central outlet 30 is blown out toward the floor, and the airflow from the left outlet 341 and the right outlet 342 Since it is cooler than the airflow from the air outlet 30, the air is blown upward from the direction that is blown out from the central air outlet 30, thereby suppressing the warm air from above and spreading the warm air widely on the floor surface, so that the warm air is not evenly distributed indoors. It can be circulated. In this case, the air flow blown out from each outlet is represented by the display unit of the remote control device as shown in FIG. However, in reality, if the airflow from the left outlet 341 and the right outlet 342 is directed too much upward, the effect of suppressing the warm air from the central outlet 30 is lost. Since the airflow is only slightly upward from the airflow from the central outlet 30, it is displayed in the same direction as shown in FIG. 9-2 on the display unit of the remote control device.

  As shown in FIG. 3, the above-described air conditioner can remotely control the operation by performing wireless two-way communication between the remote control device 10 and the indoor unit 20.

FIG. 10 is a diagram of an image example during the heating operation displayed, and FIG. 10 is a diagram of an image example during the air blowing operation displayed on the display unit of the remote control device of the air conditioner according to the present embodiment. In the display part of the remote control device of the air conditioner according to the present embodiment FIG. 12 is a diagram of a wind direction setting screen example of the left and right side fans shown, and FIG. 12 is a diagram of a wind direction setting screen example of all fans displayed on the display unit of the remote control device of the air conditioner according to the present embodiment. FIG. 13 is a diagram of an example of the air volume setting screen of the left and right side fans displayed on the display unit of the air conditioner remote control device according to the present embodiment, and FIG. 14 shows the air conditioner remote control device according to the present embodiment. It is a figure of the example of an air volume setting screen of all the fans displayed on the display part.

  First, when the operation / stop key 13e of the remote control device 10 in FIG. 4A is pressed, the air conditioner operation is started in the operation mode set at the time of shipment or the operation mode at the previous stop (step S100 in FIG. 5). Further, when the user presses any one of the cooling key 13i, the dehumidifying key 13k, the heating key 13j, the air blowing key 13m, or the automatic operation key 13o in FIG. The air conditioner operation is started in the operated mode (step S100).

  In this embodiment, for the sake of simplification, as shown in FIG. 5, the operation mode type is the cooling / dehumidification (cooling or dehumidification) operation mode in which the setting of the airflow direction is the same, and heating / air blowing (heating or air blowing). The operation mode will be described separately. When the type of the started operation mode is the cooling / dehumidifying operation mode (step S101), a display indicating that the cooling operation in FIG. 7 or the dehumidifying operation in FIG. 8 is being performed is displayed on the display unit 14 of the remote control device 10. Display. The display image is created by the remote control control unit 11 using the display image data stored in the storage unit 12 of the remote control device 10 shown in FIG.

  The feature of the remote control device of the air conditioner of the present embodiment is that the air conditioner to be operated is blown out from each air outlet even if it has a plurality of fans and a plurality of air outlets that have never existed. The air current state is displayed on the display unit 14 of the remote control device so that the user can easily see the air current state. Thereby, the user can grasp | ascertain the state of the airflow in the present driving | running condition only by seeing the display part 14 of the remote control apparatus 10, and can perform an exact airflow adjustment as needed.

  The remote control control unit 11 creates an image as shown in FIG. 6 and displays it on the display unit 14. Specifically, stereoscopic image data having a sense of depth when the indoor unit 20 is viewed from an oblique lateral direction is created and stored in the storage unit 12 in advance. The remote control control unit 11 reads out image data with a sense of depth when the indoor unit 20 is viewed obliquely from the storage unit 12. The recommended airflow state in the cooling operation mode is that the airflow (cool air) 2630 blown out from the central outlet 30 of the main unit 263 faces upward, the airflow (room air) 2610 blown out from the left outlet 341 of the left fan unit 261, and the right The air flow (room air) 2620 blown from the right outlet 342 of the fan unit 262 is directed downward. That is, in the cooling operation mode and the automatic setting mode, the cold air blown from the central outlet 30 has a higher specific gravity than the indoor air, and in order to circulate the cold air uniformly in the room, the upward air flow 2630 blown from the central outlet 30 The operation by the user is fixed as disapproved. Further, the airflows (room air) 2610 and 2620 blown out from the left outlet 341 and the right outlet 342 assist the flow of the airflow (cold air) 2630, and thus permit the operation by the user. That is, the remote control unit 11 according to the present embodiment performs control so as to display whether the airflow that can be operated by the user is changed by changing the expression form of the airflow display, or hatching or dots.

  Specifically, the display surface itself of the display unit 14 of the remote control device 10 is two-dimensional. However, when an image obtained by viewing the indoor unit 20 from an oblique lateral direction using a perspective method is displayed, it appears as a three-dimensional image. When the airflow is blown out from the air outlets in different depth directions, the depth feeling can be expressed more by displaying the airflow on the back side so as to hide the airflow on the back side. Furthermore, as shown in FIG. 6, the remote control unit 11 of the remote control device 10 of the present embodiment displays the air current 2630 that cannot be operated by the user in gray with a thin halftone dot, and the air currents 2610 and 2620 that can be operated by the user are dark. Black display with halftone dots. Thereby, the user can easily visually recognize which of the plurality of airflows is operable only by looking at the display unit 14 of the remote control device 10. Whether or not the airflow operation is possible may be identified by changing the expression form such as hatching or dots in addition to the shading. Further, if a display (LCD, organic EL, etc.) capable of color display is used for the display unit 14, it may be possible to identify whether the air flow operation is possible by expressing it with a difference in color (for example, green and yellow).

  When the operation mode is determined, the air conditioner in the present embodiment is in an automatic setting mode in which the wind direction and the air volume suitable for the operation mode are automatically set. When the user wants to arbitrarily set the wind direction and air volume, as shown in FIG. 4A, when the user presses the key 13d of the remote controller 10, the automatic setting mode is canceled and the manual setting mode is switched. . If the favor key 13d is not pressed, the automatic setting mode is always set, and the wind direction and the air volume suitable for the operation mode are automatically set. However, the air flow suitable for the operation mode is not lost depending on the adjustment of the wind direction or the air volume. Some are operable and some are not.

  The screen during the cooling operation of FIG. 7 and the screen during the dehumidifying operation of FIG. 8 (step S102) displayed on the display unit 14 of the remote control device 10 of the present embodiment are the cooling / dehumidification (cooling or dehumidification) operation mode. In auto setting mode. That is, as shown in FIG. 7, “cooling” (“dehumidification” in FIG. 8) is displayed from the top as the type of operation mode on the screen of the display unit, and the indoor unit is viewed from an oblique lateral direction. The airflow in the upward direction from the central air outlet is displayed in gray to indicate that the user cannot operate, and the airflow in the downward direction from the left and right air outlets is displayed in black, so that the user can operate It shows that the airflow is possible. The text “automatic airflow” indicating that the airflow is automatically set in the automatic setting mode is displayed. The air volume operation is the same as in the case of the wind direction. If the airflow that can be operated is displayed, the air volume adjustment can be performed if the characters “automatic air volume” are displayed. Further, the display screen displays that the set temperature of the cooling (dehumidification in FIG. 8) is “28 ° C.”, and the power saving mode “current cut” and “absent ECO” are set. Is displayed.

  When the airflow adjustment key 13a is pressed during the cooling / dehumidifying operation (Yes in step S103), the wind direction setting screen shown in FIG. 11 for setting the wind directions from the left and right outlets in conjunction with each other is displayed (step S104). As shown in FIG. 11, the setting of the right and left wind directions that can be interlocked is performed using the up and down arrows of the cross key of the air flow adjustment key 13a to adjust the vertical wind direction and the left and right arrows to adjust the left and right wind direction. Finally, the determination key 13b is pressed to complete the wind direction setting (step S105).

  Subsequently, it is determined whether or not the air volume key 13g of the remote control device 10 is pressed. If the air volume key 13g is pressed (Yes in step S106), the setting is performed in conjunction with the air volumes from the left and right outlets in FIG. An air volume setting screen is displayed (step S107). As shown in FIG. 13, the right and left airflows that can be linked and operated are selected by using the up and down arrows of the cross key of the airflow adjustment key 13a to select the desired airflow, and finally the enter key 13b is pressed to set the airflow. Completion (step S108). If the airflow adjustment key 13a is not pressed in step S103 (No in step S103), the wind direction setting process is skipped. If the air volume key 13g is not pressed in step S106 (No in step S106), the air volume setting process is skipped. If the operation / stop key 13e is pressed during the cooling / dehumidifying operation (Yes in step S109), the air conditioner operation is stopped (step S110). If the operation / stop key 13e is not pressed in step S109 (No in step S109), the process returns to step S102, and the operation mode is continued with the changed wind direction and air volume.

  On the other hand, in step S101 of FIG. 5, when the type of the started operation mode is the heating / air blowing operation mode, a display indicating that the air heating operation in FIG. 9-2 or the air blowing operation in FIG.
