  The component arrangement on the back side of the bottom panel 10 will be described with reference to FIG. FIG. 4 is a component arrangement diagram in the back cover 42 in a state where the bottom panel 10 is seen through. As shown in FIG. 4, the back cover 42 includes a pair of speaker units 43, a human body detection device 44 that detects a human body, and a sound output device substrate 45. The pair of speaker units 43 are electrically connected to the sound output device substrate 45 by lead wires, and can be stereophonically reproduced by power supplied via the sound output device substrate 45 and control signals.

  The left speaker unit 43a is disposed at the left end of the indoor unit body 1 and the right speaker unit 43b is disposed at the right end. The human body detection device 44 is disposed between the left speaker unit 43a and the right speaker unit 43b. The sound output device substrate 45 is disposed between the human body detection device 44 and one of the speaker units 43 (left speaker unit 43a in the case of FIG. 4).

  As shown in FIG. 4, each speaker unit 43 is covered with a lower wall 42 a of the back cover 42 at the lower side. Further, the upper side and the side of the speaker unit 43 are covered with a substantially U-shaped partition wall 42 b provided on the back cover 42. That is, the speaker unit 43 is covered with the lower panel 10 at the front, the back cover 42 at the rear, the lower wall 42a at the lower side, and the partition wall 42b at the upper side and the side. And the lead wire which connects the speaker unit 43 and the sound output device board | substrate 45 is wired along the outer side (side in which the speaker unit 43 is not provided) of the partition wall 42b.

  The speaker unit 43 will be described with reference to FIGS. 5 is a cross-sectional view taken along line AA in FIG. 4, and FIGS. 6 and 7 are perspective views of the speaker unit 43.

  The speaker unit 43 includes a speaker main body (not shown) including a diaphragm, a coil connected to the diaphragm, and a magnet provided around the coil in a substantially rectangular parallelepiped casing 50. Yes. The housing 50 includes flange portions 50b protruding from both side surfaces, and the speaker unit 43 is screwed to the back cover 42 via the flange portions 50b. An opening 50 a is provided on the front surface of the housing 50 so as to face the diaphragm.

  When electricity from the sound output device substrate 45 is applied to the coil, the diaphragm vibrates in response to the magnetic force of the magnet provided around the coil. This vibration further vibrates the air, which becomes a change in air pressure, passes through the opening 50a and the porous portion 41, and is heard as a sound.

  A cushioning material 50c such as polyethylene foam is provided on the front surface of the housing 50 so as to cover the periphery of the opening 50a. The front surface of the cushioning material 50c is in close contact with the inner surface of the lower panel 10 (see FIG. 5).

  Furthermore, as shown in FIG. 7, the front surface of the opening 50a is covered with a sheet 50d that allows air to pass therethrough. The sheet 50d desirably has a higher air permeability than water permeability.

  As described above, in the present embodiment, the speaker unit 43 is provided in front and below, or in front or below the air filter cleaning device 35, so that the driving sound (suction device) of the air filter cleaning device 35 is provided. High-quality sound can be delivered to the user without being affected by the suction sound and the sound of the air filter 6 moving.

  Further, the left speaker unit 43a and the right speaker unit 43b are provided at both ends in the width direction of the indoor unit main body 1, and the human body detection device 44 is disposed therebetween, so that the indoor unit main body 1 is not enlarged. The distance between the pair of left and right speaker units can be increased, and a sound with spatial expansion can be generated during stereophonic reproduction.

  In addition, the speaker unit 43 accommodates the speaker body in a housing 50 that covers the portion other than the opening 50a, and further covers the periphery with the lower panel 10, the back cover 42, the lower wall 42a, and the partition wall 42b. The sound does not leak in an unnecessary direction, and good quality sound can be delivered to the user.

  In addition, the speaker unit 43 is firmly fixed to the back cover 42, and is only in contact with the lower surface panel 10 through the cushioning material 50c. Therefore, the vibration of the vibrating body of the speaker unit 43 is reduced by the lower surface panel. 10 and the generation of abnormal noise (chattering noise) from the lower panel 10 can be prevented.

  In addition, since the lead wire connecting the speaker unit 43 and the sound output device substrate 45 is wired along the outside of the partition wall 42b, the vibration of the vibrating body of the speaker unit 43 can be prevented from being transmitted to the lead wire. It is possible to prevent abnormal noise (chatter noise) from being generated from the lead wire.

  Further, when the air that is blown from the outlet 5 touches the surface of the lower panel 10 during the cooling operation of the air conditioner, condensation may occur on the inner surface of the lower panel 10. However, in the present embodiment, since the periphery of the opening 50a is covered with the cushioning material 50c, moisture that has condensed on the inner surface of the lower panel 10 can be prevented from entering the inside of the housing 50 from the opening 50a.

  Further, by covering the front of the opening 50a with a sheet 50d that allows air to pass through, even if moisture contained in the air blown from the blowout port 5 enters through the plurality of small holes of the porous portion 41, the opening 50a is opened. Intrusion into the housing 50 from the portion 50a can be prevented. For this reason, it is possible to prevent moisture contained in the air from condensing on the diaphragm.

The sheet 50d may be provided so as to cover the back side of the porous portion 41 of the lower panel 10, but it is preferable to cover the front of the opening 50a. The reason for this will be described below. The speaker unit 43 is provided in an air conditioner that is more likely to be handled in a random manner during transportation or installation than a dedicated device (audio device) for music playback. For this reason, the case where the adhesiveness of a shock absorbing material and the inner surface of the lower surface panel 10 will become weak by the vibration at the time of transportation or installation, etc. is assumed. If the adhesiveness between the cushioning material and the inner surface of the lower panel 10 becomes weak, moisture or the like may enter from there, but even in such a case, the moisture enters the inside of the housing 50. This is because it can be prevented.

  As shown in FIG. 4, the human body detection device 44 includes a plurality of (for example, three) sensor units 44a, 44b, and 44c. The sensor elements of the sensor units 44a, 44b, and 44c are constituted by pyroelectric element type infrared sensors that detect infrared rays emitted from the human body, and the sensor elements of the sensor units 44a, 44b, and 44c detect the infrared rays. The presence / absence of a person in the detection area is detected based on the change in the amount of infrared light, and the control unit 9 determines the presence / absence of the person based on a pulse signal output in accordance with the change in the amount of infrared light.

  And since sensor unit 44a, 44b, 44c is inclined and provided with respect to the back surface (vertical surface) of the indoor unit main body 1, it can detect the area | region which should be air-conditioned below the indoor unit main body 1 from the front. It has become.

  More specifically, as shown in FIG. 8, human bodies can be detected in a plurality of areas a to g. For example, the sensor unit 44a is configured to detect the region a, the region b, the region c, and the region d, the sensor unit 44b is configured to detect the region b, the region c, the region e, and the region f, and the sensor unit 44c The region c, the region d, the region f, and the region g are configured to be detectable. With this configuration, when the human body is detected by the sensor unit 44a and the sensor unit 44b and the human body is not detected by the sensor unit 44c, it can be determined that the person (user) is in the region b. In the present embodiment, seven regions are detected using the human body detection device 44, but the present invention is not limited to this.

  Further, as shown in FIG. 9, the human body detection device 44 is configured to be able to detect, for example, a region of about 15 degrees to about 80 degrees at a vertical angle (a depression angle, an angle measured downward from the horizontal line) α. doing. Since the mounting position (height direction) of the indoor unit main body 1 is typically about 2 m high, in this case, the distance from the indoor unit main body 1 on the floor is about 0.35 m to about 7 m. An area up to 5 m can be detected.

  On the other hand, the speaker unit 43 is provided in parallel to the back surface (vertical surface) of the indoor unit body 1 in the horizontal direction. Specifically, as indicated by the alternate long and short dash line in FIG. 8, the sound axes of the left speaker unit 43a and the right speaker unit 43b are substantially parallel, and the speaker unit 43 is directed from the indoor unit body 1 to the front. Is provided. Here, the sound axis is the central axis of a region where sound propagates, and is usually the vibration direction of the diaphragm.

  Further, in the vertical direction, the speaker unit 43 is provided so as to be inclined with respect to the back surface (vertical surface) of the indoor unit body 1 so that the sound axis is included in the hatched area in FIG. Yes. Specifically, the sound axis of the speaker unit 43 is provided so as to be included in a region below the center in the detection range in the vertical direction of the human body detection device. Desirably, the detection range of the human body detection device 44 is set to a short distance area (area a), a middle distance area (area b to d), or a long distance area (area e to) according to the distance from the indoor unit body 1. When it is divided into the three regions of g), it is provided so as to be included in a region that is combined with approximately half of the far region of the short distance region and approximately half of the near region of the medium distance region. More preferably, it is provided so as to be included in the surface where the short distance area and the medium distance area are in contact.

According to this, on the head of a user sitting in a short-distance area (area a) or a lying user who has a high possibility of actively listening to music generated from the indoor unit body 1. Therefore, music or the like can be emitted from the speaker unit 43, so that high-quality music or the like can be delivered to the user. Note that the short-distance region is a region where there is a high possibility that a person exists, and in particular, a cold air and hot air from the indoor unit body 1 can be comfortably felt.

  In particular, the air conditioner has an optimal size for a room to be installed according to its cooling capacity and heating capacity, but the installation angle of the speaker unit 43 is set according to the detection range of the human body detection device 44. Thus, it is possible to provide a configuration that can deliver optimal music and the like to the user for various models having different cooling and heating capabilities.

  In the present embodiment, the human body detection device 44 has been described as including three sensor units 44a, 44b, and 44c. However, the central sensor unit 44a is omitted, and the two sensor units 44b and 44c are omitted. You may comprise. In this case, the sensor unit 44b can detect a region combining the region b and the region e and a region combining the region c and the region f. Further, the sensor unit 44c can detect a region combining the region c and the region f and a region combining the region d and the region g. In this case, it is desirable that the speaker unit 43 is provided so that the sound axis of the speaker unit 43 is included in the regions b to d.

  In the air conditioner configured as described above, the control unit 9 determines whether or not a person is present in a region obtained by dividing the detection range into a plurality based on a signal output from the human body detection device 44. For example, if the human body detection device 44 detects a human body in a predetermined detection time (for example, 2 minutes) more than a predetermined number of times, it is determined that there is a person, and if it is less than the predetermined number of times, a person exists. Judge that there is no.

  Further, the control unit 9 may determine the amount of activity (movement) of the human body based on the signal output from the human body detection device 44. Here, when it is determined that the amount of activity is large, it means that the movement of the human body is intense, and when it is determined that the amount of activity is small, it means that the movement of the human body is quiet. The amount of activity is determined in three stages according to the number of times a human body is detected by the human body detection device 44 for a predetermined detection time (for example, 2 minutes), and the amount of activity is determined when the number of human body detections is less than the predetermined number X. If the number of human detections is greater than the predetermined number Y, it may be determined that the amount of activity is large (predetermined number X <predetermined number Y).

  And in the air conditioner of this Embodiment, the direction of the up-and-down wind direction change blade | wing 7 and the left-right wind direction change blade | wing is adjusted according to the area | region where a person exists. For example, when an area where a person is present is determined as an air-conditioning area and there is one person, an up-and-down wind direction changing blade 7 and a left and right air-direction changing blade so that an air current strikes the upper body of the person in the air-conditioned area. To fix. When there are a plurality of places where people exist, the plurality of air-conditioning areas are air-conditioned one by one. The time for air-conditioning one air-conditioning area may vary depending on the amount of activity, and the area with a large amount of activity may be long, the area with a small amount of activity may be small, and air conditioning may be performed according to the user's perceived temperature.

  In addition, since the airflow reachability deteriorates as the indoor unit main body 1 and the air-conditioning region become farther, the rotation speed of the blower fan 3 is set to be higher as the indoor unit main body 1 and the air-conditioning region are farther away. . The indoor air conditioning operation is performed by controlling the refrigeration cycle components such as the compressor and the decompression device so that the indoor temperature in the air conditioning region becomes the reference indoor set temperature set by the remote controller 11.

Moreover, in the air conditioner of this Embodiment, the balance of the output (sound volume) of the left speaker unit 43a and the right speaker unit 43b is adjusted according to the area where people are present. More specifically, when it is determined that there is a person in the right area (areas b and e) when viewed from the indoor unit body 1, the output (volume) of the right speaker unit 43b is made larger than that of the left speaker unit 43a. Alternatively, when it is determined that there is a person in the left area (areas d and g) when viewed from the indoor unit main body 1, the output (volume) of the left speaker unit 43a is made larger than that of the right speaker unit 43b.

  Thereby, even when there is no user in front of the indoor unit main body 1, stereophonic reproduction with a good left / right balance for the user can be achieved.

  Further, as shown in FIGS. 3 and 10, this wall-mounted air conditioner has a front-lowering inclined surface that is located at the front part of the upper surface of the indoor unit body 1 from the suction port 4, and is located downward as it goes forward. 12 and a light source unit 14 for performing indirect illumination on the inclined surface 12 is provided.

  The light source unit 14 is formed in a strip shape as shown in FIG. More specifically, it is desirable that the light source unit 14 be disposed over substantially the entire width of the opening of the upper suction port 4.

  FIGS. 11 to 14 show the light source unit 14. The light source unit 14 diffuses light from the light source body 15 located on both sides of the light source unit 14 and the light source body 15 as shown in FIG. The light source plate 16 itself serves as a light source, and the light source body 15 and the light guide plate 16 are held in a strip-shaped housing 17 to form a unit.

  The strip-shaped casing 17 is mounted on the support base 18 from above the light guide plate 16 and the light source body 15 by supporting the light source body 15 and the light guide plate 16. It is comprised with the cover 19 which fixes the light-guide plate 16. As shown in FIG. The light guide plate 16 and the support base 18 are each composed of two parts in the longitudinal direction. Each of the two light guide plates 16 is finely processed on a flat surface (a surface perpendicular to the surface on which the light source body 15 is provided).

  As shown in FIG. 14, the light source body 15 includes a light emitting element 20 made of, for example, an LED and a light source body substrate 21 including a printed circuit board on which the light emitting element 20 is mounted. As shown in FIGS. Located on both sides, the light emitting elements 20 face each other and are arranged so as to irradiate each other toward the center.

  The light guide plate 16 and the light emitting element 20 are arranged with a gap of 0.2 mm or more and 0.8 mm or less. According to this, the damage of the light emitting element due to the contact between the light guide plate 16 and the light emitting element 20 is prevented, and the light leakage from the light emitting element 20 (the light that does not enter the light guide plate 16 out of the light from the light emitting element 20 occurs. Both) can be prevented.

  The light emitting element 20 includes at least two types of light emitting elements 20a and 20b having different emission colors. For example, in this embodiment, one of the light emitting elements 20a emits white light, and the other light emitting element 20b has a warm color. The system emits light. More specifically, the color temperature of the light emitting element 20a is preferably 6020 to 7040K, and the color temperature of the light emitting element 20b is desirably 3220 to 3710K.

The two light guide plates 16 are arranged such that their one end faces the light emitting elements 20a and 20b and the other end faces each other, and diffuses light from the light emitting elements 20a or 20b to form a long and narrow strip. The entire area of the light source unit 14 is set in a light emitting state, and light is irradiated toward the ceiling surface. At this time, the light guide plate 16 diffuses and radiates light around the light guide plate 16 and can irradiate at least a ceiling in a range wider than the width of the wall-mounted air conditioner body. That is, each of the two light guide plates 16 changes the reflection angle of the light when the light incident from the end surface on the side where the light source body 15 is provided is totally reflected by the inner surface of the light guide plate 16 and is emitted from the plane. By doing so, surface light emission is performed. Further, as indicated by an arrow B in FIG. 11, the central axis of the light emitted from the light guide plate 16 is inclined from the vertical direction of the plane toward the side where the light source body 15 is provided.

  Further, the two light guide plates 16 are arranged to face each other with a gap of 0.7 mm or more and 1.3 mm or less. According to this, it is possible to achieve both prevention of deformation of the light guide plate 16 due to the two light guide plates 16 extending in the longitudinal direction due to thermal expansion and colliding with each other and making the gap between the butted portions less noticeable. Thereby, even if the light guide plate 16 is divided into two, uniform surface light emission with less unevenness can be realized.

  In addition, the support base 18 of the strip-shaped housing 17 is configured by providing a plurality of wall plate portions 22a, 22b, 22c, and 22d (see FIG. 13) in the longitudinal direction, and a pair of wall plates positioned on the rear side. The light guide plate 16 is fitted and mounted in a recess 23 formed by the portions 22a and 22b. Further, a lead wire 25 connected to the light emitting element 20 of the light source body 15 is passed through a space portion 24 (see FIG. 13) formed by a pair of wall plate portions 22c and 22d located on the front side, and two support bases 18 are provided. The lead wire lead-out portion 26 (see FIG. 12) provided at one end of the light source body 15 is pulled out together with a lead wire (not shown) from the light-emitting element 20 of the other light source body 15 to the control unit 9 described above. They are connected and powered.

  Further, as shown in FIG. 12, the cover 19 of the strip-shaped casing 17 is formed in a substantially U shape in which a portion facing the upper surface of the light guide plate 16 is cut out, and the light source body 15 is formed at both ends thereof. A side cover portion 27 is provided to cover the outer surface side. As shown in FIG. 13, the front of the cover 19 is formed of a flat plate having a substantially arc-shaped cross section perpendicular to the longitudinal direction. On the other hand, the rear portion of the flat plate, that is, the portion of the cover 19 located on the front end face side of the light guide plate 16 is raised stepwise to form a cover wall plate portion 28. As will be described later, the upper end of the cover wall plate portion 28 is positioned above the rear end X of the light guide plate 16 installed on the front lower side so as to function as a light blocking portion that blocks light in the front horizontal direction. It is. Then, engaging claw pieces 29 are formed at several positions on the lower end of the cover wall plate portion 28, and the engaging claw pieces 29 are formed between the wall plate portions 22 b and 22 c of the respective support bases 18. The support base 18 is connected and held together, and a strip-shaped casing 17 is formed integrally with them.

  In this embodiment, the light source unit 14 configured as described above is installed so that the light guide plate 16 is in a front-down state along the inclined surface 12 on the upper surface of the indoor unit body 1 as shown in FIG. It is. Note that the installation of the light source unit 14 is not limited to the inclined installation in the front lowering state, and may be, for example, a substantially horizontal state or a rearward downward inclination installation.

  The light source unit 14 can be opened and closed by an illumination switch 31 provided in the remote controller 11 shown in FIG. 1 to switch the light source unit on and off. Further, the operation switch 32 provided on the remote controller 11 is turned on, or by operating the “ON” timer switch 33 that instructs to start the air conditioning operation after a predetermined time or a predetermined time provided on the remote controller 11. It can be turned on at the specified time.

  Further, by operating the “off” timer switch 34 provided on the remote controller 11, the light can be turned on at a predetermined time or before a predetermined time for stopping the operation, and can be turned off after the predetermined time.

  In this embodiment, the light emitting element 20 of the light source unit 14 has two types of white and warm colors as described above, and when the operation switch 32 or the “ON” timer switch 33 is operated, the white type is selected. When the “OFF” timer switch 34 is operated, the warm color light emitting element 20b is turned on.

  The operation of the air conditioner configured as described above will be described below.

  First, this air conditioner responds to each instruction by an on / off instruction by the operation switch 32 and instructions by the operation of the “ON” timer switch 33 and the “OFF” timer switch 34 as in the case of a general air conditioner. Perform air conditioning.

  In this air conditioner, since the speaker unit 43 is provided on the front surface of the indoor unit main body 1, the operation switch 32 is turned on to start the normal air conditioning operation, or the “ON” timer switch 33 or “OFF”. When timer operation is performed by operating the timer switch 34, music and voice can be output. The output music or the like may be stored in advance in a memory provided in the control unit 9 or the sound output device board 45, or via short-range wireless communication means provided in the sound output device board 45. The music stored in a music playback device (digital audio player) other than the air conditioner or the like communicated may be used.

  Music stored in advance in the memory provided in the control unit 9 or the sound output device board 45 includes, for example, a song that makes an image of awakening, a song that makes a tempo slower than a song that makes an image of awakening, and relaxation. There are three songs that make you imagine bedtime, which is slower than the song you imagined.

  This music reproduction can be performed by turning on the speaker switch provided on the remote controller 11 for turning on / off the speaker unit 43, and air conditioning without music reproduction by turning it off. Only driving can be done. That is, it is possible to select whether or not to play music according to the user's preference.

  Further, when the timer operation is performed by operating the “ON” timer switch 33 or the “OFF” timer switch 34 with the speaker switch turned on, music or voice can be output from the speaker unit 43 according to the timer operation content. it can.

  Further, since the air conditioner has the light source unit 14 on the upper surface of the indoor unit main body 1, the operation switch 32 is turned on to start the normal air conditioning operation, or the “ON” timer switch 33 or “OFF”. When timer operation is performed by operating the timer switch 34, indirect illumination can be performed.

  This indirect illumination can be performed by turning on the illumination switch 31 and closing the power supply circuit, and if it is off, only the air conditioning operation without indirect illumination can be performed. That is, it is possible to select whether to perform indirect illumination according to the user's preference.

  When the operation switch 32 is turned on with the illumination switch 31 turned on, the light emitting element 20 of the light source unit 14 is turned on together with the air conditioning operation, and indirect illumination can be performed.

  Further, when the timer operation is performed by operating the “ON” timer switch 33 or the “OFF” timer switch 34 with the illumination switch 31 turned on, the light emitting element 20 of the light source unit 14 is turned on according to the timer operation content, and indirectly. Lighting can be performed.

  The lighting control of the light source unit 14 during the timer operation will be described below with reference to the control flowchart of FIG.

In FIG. 15, this light source unit control first checks whether or not there is a driving instruction (step S1).

  If there is a driving instruction (Y in step S1), whether the driving instruction is a normal driving instruction by turning on the driving switch 32 or a timer driving instruction by operating either the "ON" timer switch 33 or the "OFF" timer switch 34 Determine (step S2).

  If it is a timer operation instruction (timer operation in step S2), it is confirmed whether it is a timer operation “ON” instruction (step S3).

  If it is a timer operation “ON” instruction (Y in step S3), it is confirmed whether the timer time has been reached (step S4), and the air conditioning operation is started when the timer time is reached (step S5). Then, it is confirmed whether the illumination switch 31 is turned on and there is an illumination lighting instruction (step S6). If there is an illumination lighting instruction (Y in step S6), the white light emitting element 20a is turned on (step S7). Perform indirect lighting.

  Next, it is confirmed whether or not the speaker switch is turned on and there is an instruction to output music or voice (step S8). If there is an output instruction (Y in step S8), the music or voice is played and the speaker unit 43 is reproduced. Is output (step S9). Then, when a predetermined time (fourth predetermined time in the present invention), for example, when the user wakes up completely and elapses to rise from the bedding (Y in Step 10), the output from the speaker unit 43 is stopped. Then, the reproduction of music or voice is stopped (step S11).

  The predetermined time until the output is stopped can be arbitrarily set by the remote controller 11. As a result, the time until the music stops can be changed depending on how much the user wants to relax in the bedding after getting up, and convenience is improved.

  In the case of a driving instruction by the “ON” timer (Y in step S3), the music to be output is not a sound source communicated via the short-range wireless communication means provided on the sound output device board 45. It is desirable that the data is stored in advance in a memory provided in the control unit 9 or the sound output device substrate 45. According to this, even when the power of the music playback device or the like is not turned on, music or the like can be reliably played back, and the convenience for the user is improved.

  If it is not a timer operation instruction but a normal operation instruction (normal operation of step S2) in the determination of whether or not it is a timer operation instruction (step S2), the air conditioning operation is started as it is (step S5), and the illumination switch 31 is further turned on. It is checked whether or not there is an illumination lighting instruction (step S6). If there is an illumination lighting instruction (Y in step S6), the white light emitting element 20a is turned on (step S7) to perform indirect illumination.

  On the other hand, if the timer operation instruction is not the timer operation “ON” (N in Step S3), it is confirmed whether the timer operation is “OFF” instruction (Step S21), and if it is a timer operation “OFF” instruction (Step S21). Y), it is confirmed whether the illumination switch 31 is turned on and there is an illumination lighting instruction (step S22).

  If there is an illumination lighting instruction (Y in step S22), the warm color light emitting element 20b is turned on (step S23), and indirect illumination is performed. Then, when a predetermined time (second predetermined time in the present invention), for example, a time enough for the user to fall asleep has elapsed (Y in step 24), the light emitting element 20b is turned off (step S25). For example, the light emitting element 20b is darkened to the minimum brightness. Thereafter, when a predetermined time (a third predetermined time in the present invention), for example, 30 seconds elapses (Y in Step 26), the light emitting element 20b is turned off (Step S27).

  Further, it is determined whether or not a predetermined time before the timer time has been reached (step S28). Note that the timer time is a time at which the air-conditioning operation is started after reaching the “off” timer set time or after a predetermined time (first predetermined time in the present invention) from the “off” timer set time. . The predetermined time in step S28 is about 30 seconds. If it has reached a predetermined time before the timer time (Y in step S28), the volume output from the speaker unit 43 is lowered.

  Thereafter, when the “off” timer set time is reached, or when a predetermined time elapses from the “off” timer set time, that is, when the timer time is reached (Y in step S30), the output from the speaker unit 43 is stopped and the music is stopped. And the reproduction of the sound is stopped (step S31) and the air-conditioning operation is stopped (step 32).

  FIGS. 16 and 17 are time charts showing examples of indirect illumination by the light source unit 14, and the situation of the air-conditioning operation by the above control and the lighting condition of the light emitting element 20 will be described below using this time chart.

  First, when the reservation time is set to t2 by operating the “ON” timer as shown in FIG. 16, the preliminary operation is started at t2a, which is a predetermined time before t2, and the air conditioning operation is started when the reservation time t2 is reached. At the same time, the warm light emitting element 20b is turned on to start indirect illumination. Here, the preliminary operation is to start the air-conditioning operation early so that the room temperature becomes the temperature set by the remote controller 11 at the reserved time.

  On the other hand, as shown in FIG. 17, when the “OFF” timer is operated during the air conditioning operation and the air conditioning operation is set to stop at time t16, the white light emitting element 20a is turned off together with the “OFF” timer setting. Then, the warm color light emitting element 20b is turned on to perform warm color indirect illumination. Then, the warm color light emitting element 20b performing the indirect illumination is turned off at time t13 when a second predetermined time has elapsed from time t12 when the “off” timer is set. Further, the light is turned off at time t14 when the third predetermined time has elapsed, and the indirect illumination is stopped.

  Thereafter, the volume output from the speaker unit 43 is lowered a predetermined time before the “OFF” timer time t16, and when the “OFF” timer time t15 is reached, the reproduction of music or the like is stopped. When the “off” timer time t15 is reached, the air conditioning operation is also stopped.

  The music output from the speaker unit 43 is stored in advance in a memory provided in the control unit 9 or the sound output device board 45 in accordance with the start time or stop time of the air conditioning operation according to the timer operation instruction. You may make it select automatically from a music. For example, if the start time or stop time of the air conditioning operation is in the morning time zone (for example, the time set in the remote controller 11 is from 4 am to 10 am), the music that makes an image of awakening is reproduced. If the start time or stop time of the air conditioning operation is a daytime period (for example, the time set in the remote controller 11 is from 10:00 am to 8:00 pm), the music that makes you feel relaxed is reproduced. If the start time or stop time of the air-conditioning operation is a night time zone (for example, the time set on the remote controller 11 is from 8 pm to 4 am), it is possible to reproduce a song that makes you imagine bedtime Good. According to this, since the music suitable for the situation is automatically selected, it is not necessary for the user to select the music to be reproduced, so that convenience is improved.

Furthermore, the music stored in advance in the memory may be automatically selected by adding the detection result of the illuminance sensor to the start time or stop time of the air conditioning operation. For example, even if the start time and stop time of the air conditioning operation are in the daytime period, if the detected value of the illuminance sensor is low, that is, it is determined that the surroundings of the indoor unit body 1 are dark, an image of awakening It is good also as what reproduces the music to make. According to this, since the music suitable for the situation is automatically selected, the convenience is further improved.

  If the instruction from the remote controller 11 is not a timer stop instruction but a normal stop instruction, the air conditioning operation is stopped, the light emitting element 20b is turned off, the indirect illumination is stopped, and the output from the speaker unit 43 is also output. It is desirable to stop. According to this, when the user wants to stop the reproduction of lighting, music, etc., the user only has to press (turn off) the operation switch of the remote controller 11, so that the user does not hesitate about the operation method and intuitively. Can be operated manually.

  Next, the function and effect of the air conditioner configured as described above as an air conditioner with indirect illumination will be described. Since the air conditioner is provided with the light source unit 14 on the upper surface of the indoor unit body 1, The machine main body 1 itself becomes a shielding wall, and indirect illumination by the light source unit 14 becomes possible.

  That is, the user can perform indirect illumination together with air conditioning simply by installing the indoor unit body 1 of the air conditioner on the wall surface of the room. Therefore, it is not necessary to newly install a shielding wall on the wall surface of the room and attach a lighting device, and indirect lighting can be realized easily and inexpensively even in an existing house.

  Moreover, the indoor unit main body 1 of the air conditioner can be installed without providing a shielding wall on the wall surface of the room. Therefore, it can be installed on the upper part of the wall surface of the room as before, and its installation position is low, giving the user a feeling of pressure, and preventing airflow from reaching far away, etc. Comfortable air conditioning is possible.

  Further, since the light source unit 14 is formed in a strip shape and is installed along the longitudinal direction of the upper surface of the indoor unit body 1, the light source unit 14 irradiates and brightens substantially the entire longitudinal direction of the indoor unit body 1. be able to.

  That is, when a lighting unit for indirect lighting is attached to a wall-mounted air conditioner, it may be considered to attach a lighting unit for indirect lighting to a part of the indoor unit body 1, for example, one end portion in the longitudinal direction of the body. However, the problem that occurs when it is attached in this manner, that is, the unbalance and the weakness that only the upper part of the indoor unit body 1 is brightened, is eliminated, and the almost entire upper area of the indoor unit body 1 is eliminated. Can be made brighter and more gorgeous and full-fledged indirect lighting, not just indirect lighting.

  In addition, in this embodiment, the light source unit 14 is installed on the inclined surface 12 of the upper surface of the indoor unit main body 1 so as to be lowered in the same manner as the inclined surface 12. The ceiling surface can be brightened surely. That is, the light guide plate 16 serving as the light source of the light source unit 14 tilts forward and downward, illuminates the ceiling surface above the front end or the front upper side of the indoor unit body 1 and reliably exhibits the indirect illumination function. Therefore, even if the wall-mounted air conditioner has a large depth dimension, good indirect illumination can be realized.

  In addition, since the light source unit 14 diffuses the light of the light emitting element 20 by the light guide plate 16, it is possible to irradiate a range wider than the main body lateral width of the indoor unit main body 1. Therefore, even if the user is located near the lower part of the wall-mounted air conditioner main body, the user can move around the indoor unit main body 1 formed by irradiation of both sides of the indoor unit main body 1 and front irradiation by tilting installation of the light source unit 14. The indirect illumination can be obtained by the indirect light, and the indirect illumination effect can be exhibited more effectively and reliably.

According to the above, assuming a standard installation state, the interval between the indoor unit body 1 and the ceiling surface is 10.
If it is 0 mm, an illuminance of about 150 lux can be achieved on the ceiling surface directly above the light source unit 14 (for example, a position at a distance of 200 mm from the wall surface on which the indoor unit body 1 is installed). An illuminance of 50 lux or more can be secured even on the ceiling surface in front of the indoor unit body 1 (for example, a position at a distance of 350 mm from the wall surface on which the indoor unit body 1 is installed). Also, an illuminance of 50 lux or more can be secured even on the ceiling surface outside the main body lateral width of the indoor unit main body 1 (for example, a position 400 mm to the left and right from the center of the indoor unit main body 1). That is, even at the upper part of the front surface or side surface of the indoor unit main body 1, it is possible to secure an illuminance (lux value) of about 1/3 or more compared to directly above the light source unit 14.

  The light source unit 14 attached to the upper surface of the indoor unit body 1 includes a strip-shaped housing 17, a light source body 15 that emits light from both ends of the strip-shaped housing 17 toward the center, and the light source body 15. Since the light guide plate 16 that guides the irradiated light along the longitudinal direction of the strip-shaped housing 17, the height of the light source unit 14 itself can be reduced, and the wall-mounted air conditioner can be Even when viewed from a distance, the atmosphere of indirect illumination can be prevented from being impaired.

  In the light source unit 14, the light guide plate 16 and the light source body 15 are supported on the support base 18 that becomes the strip-shaped casing 17, and the support base 18 covers the light guide plate 16 and the light source body 15 from above. 19, the light guide plate 16 and the light source body 15 can be securely held and unitized to be mounted on the indoor unit body 1 and can be easily attached.

  Further, the light source unit 14 is provided with a light source body 15 at both ends of a strip-shaped housing 17 holding the light guide plate 16, and radiates light from the light emitting element 20 of the light source body 15 toward each other in the central direction. Since the light source unit 14 is long along the longitudinal direction of the indoor unit body 1, a small number of light emitting elements 20 irradiate substantially the entire area above the indoor unit body 1. be able to.

  Furthermore, the light irradiation by the light source unit 14 can be made uniform with little unevenness due to the light diffusing effect of the light guide plate 16, and high-quality indirect illumination can be realized.

  In addition, as described above, the light guide plate 16 can irradiate the light in a range wider than the width of the main body of the indoor unit body 1, and the light source unit 14 is not formed to the full width of the indoor unit body 1. However, as described above, it is possible to irradiate a range wider than the main body lateral width of the indoor unit main body 1.

  On the other hand, the indoor unit main body 1 provided with the light source unit 14 has a shape in which the front portion of the upper surface of the indoor unit body 1 is inclined downwardly from the light source unit 14 on the upper surface, so that the light from the light guide plate 16 of the light source unit 14 There is a possibility that the front part of the inclined surface 12 on the upper surface of the indoor unit body 1 is lightly illuminated. In particular, in this embodiment, since the light source unit 14 itself is also inclined and installed in a front-lowering state, the front part of the inclined surface 12 on the upper surface of the indoor unit body 1 is easily lit brightly. When the front upper surface of the indoor unit body 1 becomes lighter in this way, the brightness of the ceiling surface irradiated by the light source unit 14 becomes blurred.

  However, in the present embodiment, a light shielding unit that blocks light emitted from the light guide plate 16 serving as a light source to the front portion of the light source unit 14, that is, the multiple wall plate portion 22, the lead wire 25, or the cover 19 and its Since the cover wall plate portion 28 is provided, high-quality indirect illumination can be obtained.

  That is, the multiple wall plate portions 22 b, 22 c, 22 d provided at the front portion of the support base 18 of the strip-shaped housing 17 are light emitted from the front end surface of the light guide plate 16 to the front upper surface of the indoor unit body 1. And the upper surface portion of the indoor unit body 1 in front of the light source unit 14 is prevented from becoming light and bright.

  Further, the lead wire 25 provided in the space portion 24 formed by the front wall plate portions 22c, 22d among the multiple wall plate portions 22b, 22c, 22d also radiates forward from the front end face of the light guide plate 16. Combined with the shielding effect of the wall plate portions 22b, 22c and 22d, the light emitted from the front end surface of the light guide plate 16 to the front upper surface of the indoor unit body 1 is more reliably blocked. . The lead wire 25 can be drawn out by using the space portion 24 formed between the multiple wall plate portions 22c and 22d that blocks light emitted forward from the front end face of the light guide plate 16. The configuration can be rationalized.

  Further, the cover 19 of the light source unit 14 also covers the front of the light guide plate 16 and blocks light emitted from the front end surface of the light guide plate 16 to the front upper surface of the indoor unit body 1. It is possible to prevent the upper surface portion of the indoor unit body 1 from becoming light and bright. Further, it is possible to prevent light from leaking forward from a part of the light source unit 14.

  In particular, in this embodiment, the light source unit 14 itself is inclined and installed in the front-down state, so that a part of the light emitted from the light guide plate 16 in particular from the upper surface is located in front of the light source unit 14 in the indoor unit body 1. There is a possibility that the upper surface portion may be illuminated brightly, but this light is also shielded by providing a cover wall plate portion 28 on the cover 19 that covers the front portion of the light guide plate 16, and the upper surface of the indoor unit body 1 in front of the light source unit 14. It is possible to prevent the portion from becoming light and bright. That is, since the cover wall plate portion 28 provided on the cover 19 covering the front portion of the light guide plate 16 is set up to a position higher than the rear end portion X of the light guide plate 16, The light can be blocked, and the upper surface portion of the indoor unit body 1 in front of the light source unit 14 can be prevented from becoming light and bright.

  As described above, the light shielding portion including the wall plate portion 22, the lead wire 25, the cover 19, and the cover wall plate portion 28 is shielded from the light source unit 14 in which one or a plurality of the light shielding units 14 is in the forwardly lowered state. By illuminating the upper surface portion of the indoor unit body 1 in front, it is possible to prevent this portion from becoming light and bright, and the indirect light formed on the ceiling surface can be clearly raised to provide high-quality indirect illumination.

  The wall plate portion 22 or the lead wire 25 or the cover 19 and the cover wall plate portion 28 serving as the light shielding portion can be provided with a high light shielding effect by providing all of them, but all of them are required. However, it is only necessary to provide at least the wall plate portion 22b positioned on the front end face of the light guide plate 16 as a light shielding portion.

  In this embodiment, the following effects are further provided for light shielding. That is, the cover 19 constituting the strip-shaped housing 17 of the light source unit 14 is provided with side cover portions 27 that cover the light source body 15 at both ends thereof, so that the light source body 15 can be seen from both sides of the light source unit 14. It is possible to prevent light from the light emitting element 20 or light from both sides of the light guide plate 16 from leaking in the lateral direction. Thereby, it can prevent that the side part of the indoor unit main body 1 becomes partly bright and reduces the indirect illumination effect, and can provide a better quality indirect illumination.

Further, as described in the control example, the light source unit 14 of this embodiment performs indirect illumination by turning on the white light emitting element 20a when the “ON” timer is set, and warm color when the “OFF” timer is set. Indirect illumination is performed by turning on the light emitting element 20b of the system. Therefore, at the time of waking up where the “on” timer is set to start the air-conditioning operation, it is possible to make it easy to wake up and create an active atmosphere by performing white indirect illumination close to sunlight. Then, at night when the “off” timer is set, for example, at rest or at bedtime, a warm-colored light source can be turned on to provide indirect illumination to give comfort and create an easy-to-sleep atmosphere. That is, optimal indirect lighting is possible according to the user's life scene, and a more comfortable space can be created in combination with the air conditioning effect.

  In addition, the white and warm color illumination switching is automatically performed in conjunction with the “ON” timer and the “OFF” timer, which is convenient.

  Furthermore, the indirect illumination by the light source unit 14 can be arbitrarily selected with or without indirect illumination by the illumination switch 31, and can be used properly according to preference, so that the usability is further improved.

  It is desirable that the volume output from the speaker unit 43 can be changed by operating a volume button provided on the remote controller 11. Further, when a volume button provided on the remote controller 11 is operated in a state where the speaker switch is off, the speaker unit 43 prestores in the memory provided on the control unit 9 or the sound output device board 45 for a predetermined time. It is desirable to play a single piece of music. According to this, the user can audition to what level the set volume is. For this reason, it is possible to prevent the volume at which music or the like is reproduced from the speaker unit 43 from being unexpectedly too large or too small during the “ON” timer operation.

  The volume output from the speaker unit 43 may be set to increase as the rotational speed of the blower fan 3 increases. According to this, as the noise generated by the blower fan 3 increases, the volume output from the speaker unit 43 can be increased, so that the user can easily listen to music and the like without adjusting the volume. Will improve.

  Moreover, when the human body detection apparatus 44 does not detect a person or when it is determined that the amount of activity is small for a predetermined time, the light emitting element 20b may be turned off and the indirect illumination may be stopped. Alternatively, the output from the speaker unit 43 may be stopped. According to this, when the user is absent or when sleeping and there is little movement, reproduction of lighting, music, etc. can be automatically stopped, and convenience is improved.

  As mentioned above, although the air conditioner concerning this invention has been demonstrated using the said embodiment, this invention is not limited to this. That is, the embodiment disclosed this time should be considered as illustrative in all points and not restrictive. That is, the scope of the present invention is shown not by the above description but by the scope of claims, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims.

  For example, the wall plate part 22, the lead wire 25, the cover 19, and the cover wall plate part 28 serving as a light shielding part can be made highly effective by providing all of them. All of them are not required, and at least the wall plate portion 22b located on the front end face of the light guide plate 16 may be provided as a light shielding portion.

  Further, the wall plate portion 22 serving as the light shielding portion of the light source unit 14 may not be multiple, but may be one wall plate portion 22b facing the front end portion of the light guide plate 16, and the lead wire 25 is not necessarily the light guide plate 16. Nor does it have to be routed forward.

  Further, the cover wall plate portion 28 provided so as to protrude from the cover 19 is not necessarily required unless the light source unit 14, that is, the light guide plate 16 is inclined and installed in a front-down manner.

  Further, the illumination color of indirect illumination is not limited to two colors of white and warm colors, but may be switched between warm colors and white colors in several stages, and indirect illumination is air-conditioned without providing the illumination switch 31. Indirect lighting may always be performed during operation.

  Further, the operation of the lighting switch 31 may turn on or off the light source unit 14 regardless of the operation of the air conditioner, and so on.
