The attitude of the member can be controlled.

  In the air conditioner according to the third aspect of the present invention, the acquisition unit acquires the installation height of the air conditioner as the environmental information. The control unit controls the attitude of the wind direction adjusting member based on the installation height.

  In the air conditioner according to the third aspect of the present invention, since the control unit controls the attitude of the wind direction adjusting member based on the installation height of the air conditioner, the turbulence of the air flow is independent of the installation height of the air conditioner. Can be suppressed.

  In the air conditioner according to the fourth aspect of the present invention, the acquisition unit acquires the amount of horizontal protrusion from the side wall of the obstacle located in the vertically downward direction of the air conditioner as the environmental information.

  Embodiments of the present invention are shown below. The following embodiments are merely specific examples and do not limit the invention according to the claims.

<First Embodiment>
(1) Installation Environment of Air Conditioner FIG. 1 is a diagram illustrating an example of an installation environment of an air conditioner 100 according to an embodiment of the present invention. The air conditioner 100 is installed on the side wall 201 of the room 200. Although described in detail later, the air conditioner 100 can adjust the wind direction of the conditioned air in a direction toward the side wall 201. If the operation mode of the air conditioner 100 is set to heating, warm air that is conditioned air can be made to reach the floor 202 along the side wall 201. When warm air reaches the floor surface 202, it can be expected that the room 200 in which the air conditioner 100 is installed is uniformly warmed.

  The installation height h of the air conditioner 100 is affected by the installation environment. The installation height h is a distance from the floor surface 202 to the lower surface of the air conditioner 100. The standard installation height h of the air conditioner 100 is between 1800 mm and 2200 mm. If the direction toward the side wall 201 is constant regardless of the installation height h, the height from the floor surface 202 when the conditioned air reaches the side wall 201 changes according to the installation height h. Then, the distance along which the conditioned air moves along the side wall 201 changes. When the distance along which the conditioned air moves along the side wall 201 changes, the wind speed of the conditioned air changes along the side wall 201 according to the distance. As described above, if the direction toward the side wall 201 is constant, the above-described wind speed changes according to the installation height h, and as a result, the room 200 may not be efficiently heated. For example, when the installation height h is 1800 mm and the distance along which the conditioned air runs along the side wall 201 is too short, a sufficient wind speed cannot be obtained, and the room 200 cannot be efficiently heated.

  As will be described in detail later, in the present embodiment, the air conditioner 100 adjusts the wind direction according to the installation height h, thereby realizing wind direction control suitable for the installation environment. In addition, the optimal distance as the distance along which the conditioned air runs along the side wall 201 is set in advance through simulations and experiments so that the room 200 can be efficiently warmed. Furthermore, from the viewpoint of the optimum distance, the optimum wind direction when adjusting the wind direction in the direction toward the side wall 201 is determined in advance through simulations and experiments.

The first air direction adjusting member 150 is located near the air outlet 111. The first wind direction adjusting member 150 is connected to the first driving unit 151 (see FIG. 4). The first drive unit 151 is, for example, a stepping motor. When the first drive unit 151 rotates the first wind direction adjusting member 150, the first wind direction adjusting member 150 can take a plurality of postures having different inclination angles with respect to the horizontal plane HP.

  The first air direction adjusting member 150 adjusts the air direction of the conditioned air blown out from the air outlet 111. In the present embodiment, when the wind direction is adjusted in the direction toward the side wall 201, the first wind direction adjusting member 150 maintains a predetermined posture. Specifically, as shown in FIGS. 2 and 3, the first wind direction adjusting member 150 takes a posture inclined rearward and downward. In other words, the end portion on the lower side in the vertical direction of the first wind direction adjusting member 150 is located closer to the side wall 201 than the end portion on the upper side in the vertical direction of the first wind direction adjusting member 150. When the operation of the air conditioner 100 is stopped, the first wind direction adjusting member 150 is accommodated in the accommodating portion 112.

(2-6) Second Wind Direction Adjustment Member The second wind direction adjustment member 160 is rotatably attached to the lower part of the main body casing 110. The second wind direction adjusting member 160 is located near the air outlet 111. The second wind direction adjusting member 160 is located at the rearmost among the first wind direction adjusting member 150, the second wind direction adjusting member 160, and the third wind direction adjusting member 170. That is, the second wind direction adjusting member 160 is located away from the first wind direction adjusting member 150 in the direction toward the side wall 201. The 2nd wind direction adjustment member 160 is connected to the 2nd drive part 161 (refer FIG. 4). The second drive unit 161 is, for example, a stepping motor. When the second driving unit 161 rotates the second wind direction adjusting member 160, the second wind direction adjusting member 160 can take a plurality of postures having different inclination angles α with respect to the horizontal plane HP.

  The 2nd wind direction adjustment member 160 adjusts the wind direction of the conditioned air which blows off from the blower outlet 111. FIG. When the wind direction is adjusted in the direction toward the side wall 201, as shown in FIGS. 2 and 3, the second wind direction adjusting member 160 is inclined backward and downward. That is, the end portion on the lower side in the vertical direction of the second wind direction adjusting member 160 is located closer to the side wall 201 than the end portion on the upper side in the vertical direction of the second wind direction adjusting member 160. However, as will be described in detail later, the second wind direction adjusting member 160 does not maintain a predetermined posture, but is inclined rearward and inclined with respect to the horizontal plane HP according to the installation environment of the air conditioner 100. A plurality of postures where α is different from each other can be taken. The inclination angle α of the second wind direction adjusting member 160 with respect to the horizontal plane HP is the surface of the second wind direction adjusting member 160 on the first wind direction adjusting member 150 side (the front side in the posture of the second wind direction adjusting member 160 in FIG. 3). The angle between the horizontal plane HP and the horizontal plane HP.

(2-7) Third Wind Direction Adjustment Member The third wind direction adjustment member 170 is rotatably attached to the lower portion of the main body casing 110. The third wind direction adjusting member 170 is located between the first wind direction adjusting member 150 and the second wind direction adjusting member 160. More specifically, the third wind direction adjusting member 170 is disposed on the upstream side of the conditioned air flow with respect to the first wind direction adjusting member 150. The 3rd wind direction adjustment member 170 is connected to the 3rd drive part 171 (refer FIG. 4). The third drive unit 171 is, for example, a stepping motor. As the third driving unit 171 rotates the third wind direction adjusting member 170, the third wind direction adjusting member 170 can take a plurality of postures having different inclination angles with respect to the horizontal plane HP.

  The 3rd wind direction adjustment member 170 adjusts the wind direction of the conditioned air which blows off from the blower outlet 111. FIG. In the present embodiment, when the wind direction is adjusted in the direction toward the side wall 201, the third wind direction adjusting member 170 maintains a predetermined posture. Specifically, as shown in FIGS. 2 and 3, the third wind direction adjusting member 170 takes a posture inclined forward and downward. That is, the end portion on the upper side in the vertical direction of the third wind direction adjusting member 170 is located on the side of the side wall 201 relative to the end portion on the lower side in the vertical direction of the third wind direction adjusting member 170. The third air direction adjusting member 170 forms a guide surface that guides conditioned air together with the first air direction adjusting member 150. That is, the first wind direction adjusting member 150 and the third wind direction adjusting member 170 form a substantially flush guide surface as if they were integrally formed.

(3) Functional Block of Air Conditioner FIG. 4 is a functional block diagram of the air conditioner 100. As already described, the air conditioner 100 includes the first drive unit 151, the second drive unit 161, and the third drive unit 171. The air conditioner 100 further includes a storage unit 181 and a control unit 182. The storage unit 181 stores correspondence information described later.

  The control unit 182 is a computer that includes a CPU, a ROM, a RAM, and the like. The control unit 182 is connected to the first drive unit 151, the second drive unit 161, and the third drive unit 171. The control unit 182 receives various control signals from the remote operation device 300. Examples of the control signal include a control signal related to the operation mode, a control signal related to the installation height h as an example of environmental information, and the like. The user can set the operation mode, the installation height h, and the like by operating the remote control device 300. The installation height h is stored in the storage unit 181. As described above, in the present embodiment, the control unit 182 acquires various control signals via the remote operation device 300. That is, the control unit 182 also serves as an acquisition unit that acquires environmental information regarding the installation environment of the air conditioner 100.

  The control unit 182 controls driving of the first drive unit 151, the second drive unit 161, and the third drive unit 171 in accordance with a control signal from the remote operation device 300. In particular, the control unit 182 controls the driving of the second drive unit 161 according to a control signal related to the installation height h when adjusting the wind direction in the direction toward the side wall 201. That is, the attitude of the second wind direction adjusting member 160 is controlled. At this time, in the present embodiment, the control unit 182 reads the correspondence information from the storage unit 181 and controls the attitude of the second wind direction adjusting member 160 according to the read correspondence information.

(4) Correspondence Information FIG. 5 is a diagram for explaining an example of correspondence information. The correspondence information is configured by associating installation height information and inclination angle information.

  The installation height information is information indicating the installation height h of the air conditioner 100. As described above, the standard installation height h of the air conditioner 100 is between 1800 mm and 2200 mm. Therefore, in the example of FIG. 5, “1800 mm ≦ h <1900 mm”, “1900 mm ≦ h <2000 mm”, and “2000 mm ≦ h” are described in the item of the installation height h.

  The inclination angle information as an example of the posture information is information indicating the inclination angle α of the second wind direction adjusting member 160 with respect to the horizontal plane HP. In the item of the inclination angle α with respect to the horizontal plane HP, “105 °”, “100 °”, and “95 °” are described.

  “1800 mm ≦ h <1900 mm” is associated with “105 °”, “1900 mm ≦ h <2000 mm” is associated with “100 °”, and “2000 mm ≦ h” is associated with “95 °”. . That is, the inclination angle α decreases as the installation height h increases.

(5) Example of Flowchart FIG. 6 is a flowchart of processing for adjusting the wind direction to the direction toward the side wall 201. This flowchart is started when the power of the air conditioner 100 is turned on by the user. It is assumed that the installation height h of the air conditioner 100 has already been set.

  The control unit 182 determines whether the wind direction is set in a direction toward the side wall 201 (step S101). When the control unit 182 determines that the wind direction is set in the direction toward the side wall 201 (YES in step S101), the control unit 182 reads the installation height h (step S102). The control unit 182 adjusts the inclination angle α of the second wind direction adjusting member 160 according to the installation height h. The specific processing contents are as follows.

  First, the control unit 182 determines whether the installation height h is 1800 mm or more and less than 1900 mm (step S103). When determining that the installation height h is 1800 mm or more and less than 1900 mm (YES in step S103), the control unit 182 substitutes 105 ° for the inclination angle α (step S104).

  When determining that the installation height h is 1800 mm or more and not less than 1900 mm (NO in step S103), the control unit 182 determines whether the installation height h is 1900 mm or more and less than 2000 mm. (Step S105). If it is determined that the installation height h is 1900 mm or more and less than 2000 mm (YES in step S105), the control unit 182 substitutes 100 ° for the inclination angle α (step S106).

  When it is determined that the installation height h is 1900 mm or more and not less than 2000 mm (NO in step S105), that is, the control unit 182 determines that the installation height h is 2000 mm or more, 95 ° is substituted for the inclination angle α (step S107).

  When the control unit 182 determines the inclination angle α in step S104, step S106, or step S107, the control unit 182 controls the attitude of the second wind direction adjusting member 160 so as to be the inclination angle α (step S108). . When the control of the attitude of the second wind direction adjusting member 160 is completed, or when the control unit 182 determines that the wind direction is not set in the direction toward the side wall 201 (NO in step S101), a series of processes Exit.

(6) Features of the air conditioner In the air conditioner 100 of the present embodiment, the control unit 182 adjusts the wind direction in the direction toward the side wall 201, and the second wind direction adjusting member according to the installation height h. 160 postures are controlled. In adjusting the wind direction, control suitable for the actual installation height h of the air conditioner 100 becomes possible, and as a result, turbulence of the air flow due to the installation height h can be suppressed.

  In the air conditioner 100 of the present embodiment, a plurality of pieces of inclination angle information corresponding to the installation height h are stored in the storage unit 181 in advance. The control unit 182 selects appropriate inclination angle information according to the actual installation height h. Therefore, the attitude of the second wind direction adjusting member 160 can be controlled while suppressing an increase in the processing load of the control unit 182.

  In the air conditioner 100 of the present embodiment, the control unit 182 acquires a control signal related to the installation height h from the remote operation device 300 operated by the user. Since the user inputs the installation height h via the remote control device 300, it can be expected that a more accurate installation height h is obtained.

  In the air conditioner 100 of the present embodiment, when the control unit 182 adjusts the wind direction in the direction toward the side wall 201, the end on the lower side in the vertical direction of the second wind direction adjusting member 160 is the second wind direction adjusting member 160. It is located in the side wall 201 side rather than the edge part of the vertical direction upper side. Thereby, the wind direction can be adjusted in the direction toward the side wall 201.

  In the air conditioner 100 of the present embodiment, the control unit 182 controls the attitude of the second wind direction adjusting member 160 by changing the inclination angle α of the second wind direction adjusting member 160 with respect to the horizontal plane HP. Thereby, a wind direction can be adjusted and, as a result, disturbance of the airflow by installation height h can be suppressed.

<Modification>
A modification applicable to the embodiment of the present invention will be described.

(1) Modification A
In the above description, the installation height h is set by the user via the remote operation device 300. However, when the air conditioner 100 includes a sensor, the installation height h may be automatically set according to the output value of the sensor. An ultrasonic sensor can be used as the sensor. An ultrasonic sensor is installed in the lower part of the main body casing 110 of the air conditioner 100, for example. The transmitter of the ultrasonic sensor transmits an ultrasonic wave toward the floor surface 202, and the reflected wave is received by the receiver to detect the distance to the floor surface 202, that is, the installation height h. it can.

(2) Modification B
In the above description, when the wind direction is adjusted in the direction toward the side wall 201, the first wind direction adjusting member 150 and the third wind direction adjusting member 170 maintain the predetermined posture, but the second wind direction adjusting member 160 The posture may be changed according to the posture. In this case, the correspondence information may include the tilt angle information of the first wind direction adjusting member 150 and the third wind direction adjusting member 170 in addition to the tilt angle information of the second wind direction adjusting member 160. By controlling the postures of the first wind direction adjusting member 150 and the third wind direction adjusting member 170 according to the installation height h, the wind direction can be adjusted more precisely.

(3) Modification C
In the above description, the installation height h is taken as an example of the environment information related to the installation environment, but the environment information is not limited to the installation height h. Hereinafter, other examples of environment information will be described.

  FIG. 7 is a diagram for explaining another example of the installation environment of the air conditioner 100. In the example of FIG. 7, an obstacle 400 is disposed below the air conditioner 100. Examples of the obstacle 400 include curtain rails and furniture. In the above installation environment, when the air conditioner 100 blows out conditioned air toward the side wall 201, the obstacle 400 may disturb the airflow.

  In the present modification, the control unit 182 receives a control signal related to the protrusion amount of the obstacle 400 as a control signal related to environmental information. This protrusion amount is the protrusion amount in the horizontal direction from the side wall 201. When the control unit 182 receives a control signal related to the protrusion amount of the obstacle 400, the control unit 182 controls driving of the second drive unit 161 according to the control signal. That is, the attitude of the second wind direction adjusting member 160 is controlled. Thereby, the control part 182 can adjust the wind direction of conditioned air according to the protrusion amount of the obstruction 400. FIG. The user can set the protruding amount of the obstacle 400 by operating the remote control device 300.

  As described above, according to the air conditioner 100 of the present modified example, even if the amount of protrusion changes due to the obstacle 400, the posture of the second wind direction adjusting member 160 can be controlled according to the amount of protrusion each time. The turbulence of the airflow due to the protruding amount can be suppressed.

  FIG. 8 is a diagram illustrating another example of correspondence information. The correspondence information is configured by associating the protrusion amount information and the inclination angle information.

  The protrusion amount information is information indicating the protrusion amount w of the obstacle 400 disposed below the air conditioner 100. In the example of FIG. 8, “0 mm ≦ w <100 mm”, “100 mm ≦ w <200 mm”, “200 mm ≦ w <300 mm”, and “300 mm ≦ w” are described in the item of the protrusion amount w.

  The tilt angle information is information indicating the tilt angle α of the second wind direction adjusting member 160 with respect to the horizontal plane HP. In the item of the inclination angle α with respect to the horizontal plane HP, “105 °”, “100 °”, “95 °”, and “60 °” are described.

  “0 mm ≦ w <100 mm” is associated with “105 °”, “100 mm ≦ w <200 mm” is associated with “100 °”, and “200 mm ≦ w <300 mm” is associated with “95 °”. , “300 mm ≦ w” is associated with “60 °”. That is, as the protrusion amount w increases, the inclination angle α decreases.

  The control unit 182 appropriately controls the attitude of the second wind direction adjusting member 160 by adjusting the inclination angle α of the second wind direction adjusting member 160 according to the protrusion amount w, as in the flowchart of FIG. 6. Can do.

  By the way, when the protrusion amount w is not less than a preset threshold value (300 mm in the present modification), for example, a large size having a front and rear width wider than the front and rear width of the air conditioner 100 below the air conditioner 100. When the obstacle 400 is arranged, it is difficult to keep the conditioned air along the side wall 201. In this case, the control unit 182 does not have to direct the conditioned air in the direction toward the side wall 201. Specifically, it is as follows.

  FIG. 9 is an external perspective view of the air conditioner 100. As shown in FIG. 9, the control unit 182 may control the attitude of the second wind direction adjusting member 160 so that the conditioned air is not in the direction toward the side wall 201 but in the direction away from the side wall 201. At this time, the end of the second wind direction adjusting member 160 on the upper side in the vertical direction is located closer to the side wall 201 than the end of the second wind direction adjusting member 160 on the lower side in the vertical direction. That is, the second wind direction adjusting member 160 takes a posture inclined forward and downward. For example, as described above, the inclination angle α of the second wind direction adjusting member 160 may be set to 60 °. Thereby, the disturbance of the airflow by an installation environment can be suppressed. Note that the first wind direction adjusting member 150 and the third wind direction adjusting member 170 may also take a posture inclined forward and downward in accordance with the posture of the second wind direction adjusting member 160.

  The controller 182 may control the attitude of the second wind direction adjusting member 160 according to the height of the obstacle 400. For example, even if the large obstacle 400 as described above is arranged below the air conditioner 100, if the height of the obstacle 400 is relatively low, the conditioned air is allowed to run along the side wall 201. be able to. Therefore, even if the protrusion amount w is equal to or greater than a preset threshold value, the control unit 182 harmonizes in the direction toward the side wall 201 if the height of the obstacle 400 is less than another preset threshold value. You may adjust the wind direction of air.

  In the case where the air conditioner 100 includes a sensor, the protrusion amount w may be automatically set according to the output value of the sensor.

(4) Modification D
In the above description, when the control unit 182 adjusts the air direction of the conditioned air in the direction toward the side wall 201, the guide surface of the first air direction adjusting member 150 and the guide surface of the third air direction adjusting member 170 are substantially flush. However, it does not have to be flush. When the third wind direction adjusting member 170 overlaps the first wind direction adjusting member 150, the guide surface of the first wind direction adjusting member 150 and the guide surface of the third wind direction adjusting member 170 may be formed in a stepped shape. By positioning the third wind direction adjusting member 170 so as to ride on the first wind direction adjusting member 150, the amount of air entering between the first wind direction adjusting member 150 and the third wind direction adjusting member 170 can be reduced.

(5) Modification E
In the above description, the storage unit 181 stores the correspondence information, but may store a mathematical formula for deriving the inclination angle of the second wind direction adjusting member 160. In this case, the mathematical formula includes the installation height h or the protrusion amount w as a parameter. Thereby, the inclination angle according to the installation environment can be derived.

(6) Modification F
In the above description, the third wind direction adjusting member 170 is pivotally attached to the lower portion of the main body casing 110, but may be attached so as to freely advance and retract. That is, the third wind direction adjusting member 170 may perform a linear motion instead of a circular motion. Further, the third wind direction adjusting member 170 may be fixed to the lower portion of the main body casing 110 while maintaining a specific posture. In this case, since the attitude of the third wind direction adjusting member 170 is unchanged, the control unit 182 only needs to control the attitudes of the first wind direction adjusting member 150 and the second wind direction adjusting member 160.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be made to the above embodiments. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.
