Description

  The present invention relates to an air conditioner having an ion generator.

  In recent years, high value-added air conditioners equipped with an ion generator that generates positive and negative ions by discharge have appeared. By the way, positive and negative ions have a property of disappearing when they collide with an obstacle in the process of being sent by an air flow.

  Therefore, the position of the ion generator in the air conditioner is preferably located downstream from the louver installed at the air outlet, and is usually provided slightly above the outlet. However, at this position, when the wind direction of the air flow blown out from the outlet is adjusted diagonally downward by the louver, ions are difficult to ride in the air flow, and the number of positive and negative ions carried is small, so the loss increases. There was a problem.

As an air conditioner that solves the above-described problem, as shown in Patent Document 1, an air conditioner in which an ion generating electrode for generating ions is formed on the louver surface is known. In the air conditioner, there are no obstacles that obstruct the flow on the downstream side of the airflow flowing along the surface of the louver blade, so that the number of positive and negative ions generated from the ion generating electrode body decreases. In addition, the supply efficiency of positive and negative ions can be increased.

  By the way, in the air conditioner of the said structure, when changing the direction of the wind which blows off from a blower outlet largely, a louver will be largely inclined with respect to the flow of a wind. At this time, if the ion generating electrode is formed on the surface of the louver that faces the upstream side of the wind flow, the generated ions are pressed against the louver surface by the wind blown from the outlet, so positive and negative ions collide with the louver. The number of ions decreases.

  On the other hand, when the ion generating electrode is formed on the surface of the louver facing the downstream side with respect to the wind flow, the generated ions cannot be smoothly put on the wind blown from the outlet, and the ion generating electrode It becomes difficult to send the ions generated in the far distance.

  In view of the above, an object of the present invention is to provide an air conditioner that can efficiently release ions to a distant place even when the direction of the wind blown from the blowout port is greatly changed.

  In order to achieve the above object, an air conditioner according to the present invention includes a wind direction changing plate that changes the direction of the wind blown from the air outlet, and an ion generation unit provided on the wind direction changing plate, and the wind direction changing plate includes: Further, a guide means is provided for guiding the wind flowing along the wind direction changing plate to the ion generating section when the inclined posture is oriented with an angle with respect to the blowing direction of the wind.

  According to the above configuration, since the guide means is provided, even if the wind direction changing plate is oriented at an angle so as to be inclined with respect to the wind blowing direction, the ions generated in the ion generating part are not allowed to flow along the wind direction changing plate. It is possible to carry it smoothly to a distant place on the car.

  Specifically, the guide means includes a guide plate that is disposed opposite to and spaced from the wind direction changing plate, and a ventilation path is formed between the guide plate and the wind direction changing plate, and the ion generation unit is provided in the ventilation path. Can be configured.

  According to the above configuration, while the ions are generated in the space in the ventilation path, the generated ions can be smoothly led out to the outside of the ventilation path by the wind passing through the ventilation path. In addition, as a guide means, what is necessary is just to provide the guide plate, and it is also possible to provide the side wall for supporting a guide plate suitably.

  Moreover, it is also possible to use the tubular member made into the form which enclosed the surroundings of the ion generating part with the guide plate and the side wall as a guide means. In this case, the tubular member may be installed on the wind direction changing plate so that the length direction thereof is parallel to the surface of the wind direction changing plate, and the ion generation unit may be disposed inside the tubular member.

  The guide means is preferably arranged so that the position of the upstream end of the wind flow direction in the inclined posture is downstream of the wind direction change plate on the downstream side of the wind flow direction. As a result, the amount of wind introduced into the guide means can be increased, and the wind passing through the guide means and the wind bypassing the guide means can be smoothly merged to efficiently carry ions to a distance. .

  In addition, the guide plate is formed so that the end on the upstream side in the wind flow direction in the inclined posture is inclined with respect to the wind direction changing plate so that the distance from the wind direction changing plate increases toward the upstream side. Also, the amount of wind introduced into the guiding means can be increased.

  In addition, if a guard member that guards the entry of fingers into the ventilation path is installed at the entrance / exit of the ventilation path formed by the guide means, it is possible to prevent an electric shock in the ion generating section, and to ensure safety as an air conditioner. Can increase the sex.

The ion generator is either a positive ion represented by H ⁺ (H ₂ O) _m (m is an arbitrary natural number) or a negative ion represented by O ₂ ⁻ (H ₂ O) _n (n is an arbitrary natural number). Any one may be used as long as it generates one ion, and positive and negative ions may be alternately generated from the same ion generation unit. However, it is preferable to generate positive ions and negative ions separately.

  When the positive ion generator and the negative ion generator are separately formed as the ion generators, the ion generators are arranged in parallel at intervals with respect to the direction of the wind flowing along the wind direction change plate. Is preferred. As a result, it is possible to suppress the positive and negative ions generated in each ion generation unit from disappearing due to contact and reaction with each other.

  Specific examples of the wind direction changing plate described above include a wind guide panel provided on the front side of the outlet as a part of the cabinet. Further, in the air conditioner having the wind guide panel, an auxiliary louver that changes the vertical wind direction while changing the vertical angle according to the orientation of the wind guide panel and rectifying the wind blown from the air outlet is provided. It is also possible to use a change plate and provide an ion generating part here.

  In addition, at least one louver of a group of louvers that are installed at the air outlet of a conventional air conditioner can be used as a wind direction changing plate as used in the present invention, and an ion generation unit and guide means can be provided. It is.

  As described above, according to the present invention, the wind direction change plate is provided with the guide means, and the ion generation unit is provided in the ventilation path formed in the guide means. Therefore, the wind direction change plate is oriented at an angle with respect to the wind flow direction. Even in this case, ions can be efficiently emitted far away.

[First Embodiment]
The indoor unit of the air conditioner according to the first embodiment of the present invention is shown in FIGS. The indoor unit includes a heat exchanger 1 and an indoor fan 2, which are housed in a cabinet 3. The cabinet 3 is formed in a box shape having a depth longer than the height, and has a curved surface from the front surface to the bottom surface. A suction port 4 is formed on the upper surface of the cabinet 3, and an outlet 5 is formed on the curved surface.

  An air passage 6 extending from the suction port 4 to the blowout port 5 is formed inside the cabinet 3, and the heat exchanger 1 and the indoor fan 2 are disposed in the air passage 6. A filter 7 is disposed between the suction port 5 and the heat exchanger 1 to remove dust from the indoor air sucked from the suction port 4. A cleaning device 8 for cleaning the filter 7 is provided.

  The cleaning device 8 moves the filter 7 in the cabinet 3 to pass through the dust removing unit 9, and the dust removing unit 9 removes dust attached to the filter 7. A guide path 10 that is curved in a U shape in a side view is formed on the front side in the cabinet 3, and a moving unit including a motor and a gear reciprocates the filter 7 along the guide path 10. In the dust removing unit 9, the rotating brush scrapes off dust from the passing filter 7, and the suction fan sucks and discharges the scraped dust by flowing air in a direction substantially parallel to the filter 7 (left and right direction). .

  An air guide panel 20 that opens and closes the air outlet 5 is provided on the curved surface of the cabinet 3. As shown in FIGS. 3 to 6, the wind guide panel 20 can be opened both vertically and an opening / closing mechanism for opening and closing the wind guide panel 20 is provided.

  The wind guide panel 20 is formed by a single curved panel, and the width of the wind guide panel 20 is the same as the width of the cabinet 3 and is larger than the width of the outlet 5. And the front panel 21 is formed in the front surface of the cabinet 3 so that it may become one step lower from the middle part of the front surface to the bottom surface. Thereby, a recessed part is formed in the whole width direction, and the wind guide panel 20 fits into the recessed part. An opening is formed in the front panel 21 that forms the recess, and this opening is the air outlet 5. Therefore, the wind guide panel 20 is positioned in front of the air outlet 5 and covers the air outlet 5 and the front panel 21 around the air outlet 5. At this time, the wind guide panel 20 is in the closed position shown in FIG.

  When in the closed posture, a gap is formed between the front end and rear end of the wind guide panel 20 and the cabinet 3. As shown in FIGS. 4 and 6, when the wind guide panel 20 opens and closes, the end of the wind guide panel 20 enters the gap. The wind guide panel 20 can rotate smoothly without hitting the cabinet 3. Further, when the wind guide panel 20 is opened to the maximum in the upper opening or the lower opening, the front and rear ends of the wind guide panel 20 are blown out so that the wind guide panel 20 contacts the cabinet 3. Prevents the wind from leaking. In particular, in the case of cold air, condensation on the bottom surface side of the cabinet 3 can be prevented.

  Thus, the outer surface of the wind guide panel 20 constitutes a smooth curved surface extending from the front surface to the bottom surface of the cabinet 3. That is, the wind guide panel 20 is a member constituting a part of the front surface of the cabinet 3. In other words, a part of the panel of the cabinet 3 is used as the wind guide panel 20. Thereby, the wind guide panel 20 becomes a long panel having a long overall length as compared with the louver employed in the conventional air conditioner.

  The wind guide panel 20 opens in either the upper or lower direction by rotating in different directions around the upper and lower axes. The upper shaft 23 and the lower shaft 22 are formed in parallel with the left-right direction of the cabinet 3. As shown in FIGS. 5 and 6, the wind guide panel 20 opens downward around the lower shaft 22 during the cooling operation. In this downward opening posture, the wind guide panel 20 is connected to the lower wall of the air outlet 5, and a long nozzle is formed by the air guide panel 20 and the upper wall of the air outlet 5. The wind guide panel 20 guides the cool air obliquely upward, and the cool air blows out along the ceiling.

  As shown in FIGS. 3 and 4, it opens upward around the upper shaft 23 during heating operation. In this upward-opening posture, the air guide panel 20 shields the front of the air outlet 5, suppresses the warm air blown forward, and guides the warm air toward the floor surface. Even at the initial stage of the cooling operation, the air guide panel 20 is in the upwardly open posture, and the cool air is blown out in the direction of the floor surface to perform rapid cooling. As shown in FIG. 2, the wind guide panel 20 is closed when the operation is stopped, covers the air outlet 5, and is integrated with the cabinet 3.

  In the present embodiment, the blowout port 5 is provided with an auxiliary louver 800 in addition to the vertical louver 24. The vertical louver 24 changes the wind direction in the left-right direction by changing the angle in the left-right direction. The auxiliary louver 800 is provided in front of the vertical louver 24 and at the outlet portion of the air outlet 5, and the direction of the wind blown out from the air outlet 5 while changing the vertical angle according to the attitude of the air guide panel 20 and rectifying the air. Change the vertical wind direction of W0. In the present embodiment, the auxiliary louver 800 is used as a wind direction changing plate, and the auxiliary louver 800 is provided with guide means and an ion generation unit. Hereinafter, the auxiliary louver 800 will be described in detail.

  The auxiliary louver 800 is formed in a plate shape that is long in the left-right direction, and the front and rear ends are tapered. On the rear end side (base end side), a rotation shaft 801 having an axial direction in the left-right direction is fixed to a shaft coupling portion formed in the left and right end portions. The rotary shaft 801 is disposed on the upper wall 5a side among the upper and lower walls 5a and 5b forming the air passage 6 reaching the blower outlet 5, and is rotatably supported through the left and right side walls of the blower outlet 5. The A louver motor 803 is connected to the shaft end of the rotating shaft 801 via a speed reduction mechanism (not shown) (see FIG. 7), and the louver motor 803 is driven and controlled by the control device 41.

  As shown in FIGS. 16 to 17, the auxiliary louver 800 includes an upper member 804 and a lower member 805. An ion generator 920 is accommodated in the auxiliary louver 800. That is, one or more ion generators 920 are incorporated into the auxiliary louver 800 by combining the upper member 804 and the lower member 805 with the ion generator 920 interposed therebetween. In the present embodiment, three ion generators 920 are incorporated in the auxiliary louver 800.

  An opening 805a is formed in the lower member 805, and a part of the ion generator 920 is exposed from the opening 805a. An ion generator 921a is formed in the portion of the ion generator 920 exposed from the lower member 805, and positive and negative ions are generated from the ion generator 921a. The portion of the ion generator 920 exposed from the opening 805a and the surface of the lower member around the opening 805a are formed to be flush with each other so that the wind flows smoothly along the surface of the lower member.

  As shown in FIGS. 18 to 20, the ion generating device 920 includes an ion generating element 910, a case 921, a power input connector 922, a driving circuit 923, a high voltage generating circuit 924, and a positive high voltage generating circuit 925. And a negative high voltage generation circuit 926.

  The ion element 910 includes the induction electrode 901, the discharge electrode 902, and the substrate 903. The discharge electrode 902 has a needle-like tip. The substrate 903 has a through hole 903a for inserting the discharge electrode 902 and a through hole 903b for inserting the insertion portion 901d2 of the substrate insertion portion 901d.

  The acicular discharge electrode 902 is supported by the substrate 903 in a state of being inserted or press-fitted into the through hole 903a and penetrating the substrate 903. As a result, one end of the discharge electrode 902 having a needle shape protrudes to the front surface side of the substrate 903, and a lead wire or a wiring pattern is electrically connected to the other end protruding to the back surface side of the substrate 903 by the solder 904. It becomes possible.

  The insertion portion 901d2 of the induction electrode 901 is inserted into the through hole 903b and supported by the substrate 903 in a state of penetrating the substrate 903. In addition, a lead wire or a wiring pattern can be electrically connected to the tip of the insertion portion 901 d 2 protruding from the back surface side of the substrate 903 by solder 904.

  In a state where the induction electrode 901 is supported by the substrate 903, the stepped portion at the boundary between the support portion 901 d 1 and the insertion portion 901 d 2 comes into contact with the surface of the substrate 903. Thus, the top plate portion 901a of the induction electrode 901 is supported with a predetermined distance from the substrate 903. The tip of the substrate support portion 901e of the induction electrode 901 is in contact with the surface of the substrate 903 in an auxiliary manner. That is, the induction electrode 901 can be positioned in the thickness direction with respect to the substrate 903 by the substrate insertion portion 901d and the substrate support portion 901e.

  In addition, with the induction electrode 901 supported by the substrate 903, the discharge electrode 902 has a needle-like tip positioned at the center of the circular through-hole 901b and the thickness of the peripheral edge of the through-hole 901b (that is, It is arranged so as to be located within the range of the bending length of the bent portion 1c.

  In order to release positive ions and negative ions, both the acicular tip position of the discharge electrode 902 that generates positive ions and the acicular tip position of the discharge electrode 902 that generates negative ions are used. The induction electrode 901 and the discharge electrode 902 are disposed with a predetermined distance from each other, aligned with the center of the through hole 901b of the induction electrode 901, and within the thickness range of the through hole 901b of the induction electrode 901. The needle-shaped tip of the head is opposed to the air space.

  In the ion generating element 910, the plate-like induction electrode 901 and the needle-like discharge electrode 902 are arranged with a predetermined distance as described above, and a high voltage is applied between the induction electrode 901 and the discharge electrode 902. Is applied, corona discharge occurs at the tip of the acicular discharge electrode 902. The corona discharge generates at least one of positive ions and negative ions, and the ions are released from the through-hole 901b provided in the induction electrode 901 to the outside of the ion generating element 910. Furthermore, it becomes possible to discharge | release ion more effectively by adding ventilation.

Here, the positive ion is a cluster ion in which a plurality of water molecules are attached around a hydrogen ion (H ⁺ ), and is represented as H ⁺ (H ₂ O) _m (m is an arbitrary natural number). Negative ions are cluster ions in which a plurality of water molecules are attached around oxygen ions (O ₂ ⁻ ), and are expressed as O ₂ ⁻ (H ₂ O) _n (n is an arbitrary natural number).

If positive ions and negative ions are released, H ⁺ (H ₂ O) _m (m is an arbitrary natural number) in the air and O ₂ ⁻ (H ₂ which is a negative ion). O) _n (n is an arbitrary natural number) is generated in an approximately equivalent amount, so that both ions surround mold fungi and viruses floating in the air, and the active species hydroxyl radicals (・ By the action of OH), it is possible to remove floating fungi and the like.

  In the above ion generator, positive corona discharge is generated at the tip of one discharge electrode 902 to generate positive ions, and negative corona discharge is generated at the tip of the other discharge electrode 902 to generate negative ions. The waveform to be applied is not particularly limited here, and is a high voltage such as a direct current, an alternating current waveform biased positively or negatively, and a pulse waveform biased positively or negatively. The voltage value is sufficient to generate a discharge, and a voltage region in which a predetermined ion species is generated is selected.

  The power input connector 922 receives supply of DC power or commercial AC power as input power. The drive circuit 923 supplied with the input voltage via the power input connector 922 drives the high voltage generation circuit 924 to boost the input voltage and generate a high voltage. One end of the high voltage generation circuit 924 is electrically connected to the induction electrode 901. The high voltage generation circuit 924 applies a positive high voltage to the induction electrode 901 to the acicular discharge electrode 902 that generates positive ions through the positive high voltage generation circuit 925, and also passes through the negative high voltage generation circuit 926. A high negative voltage is applied to the induction electrode 901 to the acicular discharge electrode 902 that generates negative ions.

  The case 921 accommodates therein an ion generation element 910, a power input connector 922, a drive circuit 923, a high voltage generation circuit 924, a positive high voltage generation circuit 925, and a negative high voltage generation circuit 926. The power input connector 922 is exposed to the outside of the case 921 in order to receive external input power.

  The case 921 has a hole 921a in a wall portion facing the through hole 901b of the ion generating element 910, and this hole 921a is an ion generating portion. That is, with the ion generator 920 incorporated in the auxiliary louver 800, the ion generator 921a is exposed to the outside through the opening 805a, and positive and negative ions are released to the outside.

  As shown in FIG. 21, the ion generation unit includes a positive ion generation unit 921a that generates positive ions and a negative ion generation unit 921a that generates negative ions, and each ion generation unit 921a, 921a is arranged so as to be parallel to the front-rear direction A while being incorporated in the auxiliary louver 800.

  The auxiliary louver 800 protects the wind W0 blown from the outlet 5 from directly contacting the ion generator 921a, and the wind flowing along the auxiliary louver 800, which is a wind direction change plate, to the ion generator 921a. Guiding means for guiding is provided.

  As shown in FIG. 22, the guide means includes a guide plate 891 disposed to face the lower member 805 at a position away from the lower member 805 so as to cover the ion generating portion 921 a. In other words, the guide plate is at least larger than the ion generator 921a. In the present embodiment, a size that covers the case 921 is used. And the space between the guide plate 891 and the lower member 805 is made into the ventilation path 892, and a wind flows in the direction shown by the arrow.

  In the present embodiment, the guide plate 891 is disposed to face the surface of the lower member 805 with a certain interval. Therefore, when the surface of the lower member 805 is curved, the guide plate 891 is similarly curved. Thereby, the ventilation path 892 is formed in parallel along the lower member 805. Note that the constant interval is preferably an interval that can ensure a spatial distance and a creepage distance from the electrode of the ion generating element 910.

  The guide plate 891 is arranged such that the position of the end portion 891a on the upstream side in the wind flow direction is downstream of the position of the base end 800a of the auxiliary louver 800 in the wind flow direction. Further, as shown in FIG. 23, the guide plate 891 has a shape of the end portion 891a on the upstream side in the wind flow direction with respect to the auxiliary louver 800 so that the distance from the auxiliary louver 800 increases toward the upstream side. It is also possible to form it so as to be inclined, so that the air can be taken into the air passage 892 more efficiently.

  Guard members 893 that guard the entry of fingers into the ventilation path 892 are installed at the inlet 892a and the outlet 892b of the ventilation path 892. As the guard member 893 in the present embodiment, an elongate crosspiece that is crossed in the left-right direction at an intermediate position between the guide plate 891 and the lower member 805 at the entrance / exit of the ventilation path 892 is used.

  The guard member 893 has a tapered shape at both front and rear ends, and has a shape with low air resistance so as not to disturb the flow of the wind flowing through the ventilation path 892 as much as possible. In addition, the ion generation part 921a in this embodiment is the structure where the acicular discharge electrode 902 was installed in the recessed part, it becomes possible to take a creeping distance long, and it becomes possible to improve safety | security further.

  The operation of the auxiliary louver 800 having the above configuration will be specifically described. As shown in FIG. 1 and FIG. 2, the auxiliary louver 800 can be accommodated in the space in the air outlet 5 by taking a posture in which the auxiliary louver 800 faces upward and touches the upper wall 5 a and can close the air guide panel 20. It becomes.

  The control device 41 is in an upwardly open posture in which the lower end of the wind guide panel 20 is opened forward around the upper shaft 23, and an inclined posture in which the auxiliary louver 800 is oriented at an angle with respect to the wind flow so as to change the wind direction. The louver motor 803 is driven and controlled to take Further, the control device 41 drives and controls the louver motor 803 so as to control the orientation of the auxiliary louver 800 in parallel with the wind flow in the downward opening posture in which the upper end of the wind guide panel 20 is opened downward about the lower shaft 22.

  More specifically, the control device 41 supports the air guide panel 20 so that the front of the air outlet 5 is shielded by the auxiliary louver 800 while the air blown out toward the front is pushed down and guided downward by the auxiliary louver 800. The posture of the louver 800 is controlled. In addition, the angle of the auxiliary louver 800 is controlled so that the wind direction is changed in two steps by applying the wind blown from the outlet 5 to the two members of the auxiliary louver 800 and the wind guide panel 20 in the upward opening posture of the wind guide panel 20. To do. Below, the attitude | position of the wind guide panel 20 and the auxiliary louver 800 is illustrated. In FIG. 8, FIG. 11, FIG. 12, and FIG. 13, the auxiliary louver is omitted for easy understanding of the mechanism of the moving part and the restricting part of the wind guide panel described later.

  FIG. 4 shows an example in which the wind guide panel is in the upwardly open posture and the auxiliary louver 800 is oriented at an angle with respect to the wind flow, and FIG. 24 is a partially enlarged view of FIG. As shown in the figure, when the auxiliary louver 800 is inclined with respect to the wind W0 blown forward from the outlet 5 through the air passage 6, the lower member 805 faces the upstream side with respect to the flow of the wind W0. The wind W0 directly hits the surface of the lower member. In order to carry the ions generated by the ion generating portion 921a to the distant place on the wind flow, it is preferable to form the ion generating portion 921a on the surface of the lower member 805 directly hit by the wind.

  However, when the ion generating portion 921a is provided on the surface of the lower member 805, when the auxiliary louver 800 is inclined, most of the ions generated by the wind blown toward the lower member 805 are pressed against the surface of the lower member 805. May disappear.

  Therefore, in the present invention, as shown in the figure, by providing a guide plate 891, it is possible to protect the ion generator 921a from being directly exposed to the wind W0 and to use the ventilation path 892 as a space for generating ions. Yes. Further, the wind W0 hitting the lower member 805 on the upstream side of the ventilation path 892 is introduced into the ventilation path 892 while changing the direction of the wind, and ions generated in the ventilation path 892 are introduced to the surface of the auxiliary louver (lower member). Along the downstream side. The wind W1 containing ions derived from the ventilation path 892 smoothly merges with the wind W2 whose direction of wind has been changed on the surface of the guide plate 891 or the surface of the lower member 805, and the positive and negative ions are carried on the wind W2 and efficiently far away. It is possible to release well. In addition, the number of ions generated by the air blown toward the lower member 805 is pressed against the surface of the lower member 805 and disappears can be reduced.

  FIG. 6 shows an example in which the wind guide panel is in the downward opening posture and the auxiliary louver 800 is oriented parallel to the flow of the wind W0, and FIG. 25 is a partially enlarged view of FIG. In this example, the wind guide panel 20 rotates downward about the lower shaft 22 and takes a substantially horizontal posture. That is, the wind guide panel 20 is connected to the lower wall of the air outlet 5 when in the downward opening posture, and a long nozzle is formed by the air guide panel 20 and the upper wall 5a of the air outlet 5. Therefore, the wind guide panel 20 can guide the wind diagonally upward and blow it out to the far side along the ceiling. At this time, since the lower member 805 and the guide plate 891 of the auxiliary louver 800 are oriented in parallel with the flow of the wind W0, the wind W0 is introduced into the ventilation path 892 without being blocked by the guide plate 891, and is blown out together with the ions at the outlet 5 It works to guide the air blown from the far.

  Next, a mechanism for opening or closing the wind guide panel will be described. Support members 31 are provided on both sides of the inner surface of the wind guide panel 20 in the left-right direction. The wind guide panel 20 is detachably attached to the support member 31. The support material 31 is attached to the cabinet 3 via a rod 32. That is, the wind guide panel 20 is attached to the cabinet 3 via the rod 32 and is detachable from the cabinet 3.

  As shown in FIG. 5, claws 33 that are slidable in the left-right direction are provided on both sides of the wind guide panel 20 in the left-right direction. The claw 33 is opposed to the peripheral wall formed in the front-rear direction and is urged toward the peripheral wall by an urging member such as a spring. The wind guide panel 20 is attached to the support member 31 by sandwiching the support member 31 between the claw 33 and the peripheral wall. The wind guide panel 20 can be removed from the support member 31 by sliding the claw 33 in the direction away from the peripheral wall.

  In addition, what is necessary is just to provide the nail | claw 33 in at least one side in the front-back direction. In this case, on the other side, either one of the wind guide panel 20 or the support material 31 is provided with a pin, and the other is formed with a hole. The wind guide panel 20 is engaged with the support member 31 by fitting the pins into the holes. When the claw 33 is provided on one side, the claw 33 is preferably provided on the rear side in consideration of workability. In this case, the user can attach and detach the wind guide panel 20 while looking at the nail 33 in a state where the wind guide panel 20 is in the downward opening posture. Therefore, the attachment / detachment operation can be easily and reliably performed, and the operation can be performed while supporting the wind guide panel 20 with one hand, so that the wind guide panel 20 can be prevented from falling.

  The upper shaft 23 of the wind guide panel 20 is provided on the front side of the support material 31, and the lower shaft 22 is provided on the rear side of the support material 31. The vertical shafts 22 and 23 are arranged along the left-right direction, and both ends are supported so as to be separated from the support material 31. The vertical shafts 22 and 23 are located outside the blower outlet 5 and in front of the blower outlet 5 in the front / rear and left / right directions. Therefore, the vertical shafts 22 and 23 do not disturb the flow of the wind blown out from the air outlet 5.

  The support material 31 may be integrated with the wind guide panel 20. The rod 32 is directly attached to the wind guide panel 20. In this case, the wind guide panel 20 can be attached to and detached from the cabinet 3 by detachably attaching the rod 32 to the wind guide panel 20.

  In the air conditioner, an outdoor unit (not shown) is installed outside the indoor unit. The outdoor unit includes a compressor, a heat exchanger, a four-way valve, an outdoor fan, and the like, and a refrigeration cycle 40 is formed by these and the indoor heat exchanger 1. And as shown in FIG. 7, the control apparatus 41 which controls the refrigerating cycle 40 is provided in an indoor unit. A control device 41 composed of a microcomputer controls the refrigeration cycle 40 based on a user instruction and detection signals of various sensors 42 such as a temperature sensor that detects a room temperature and an outside air temperature, and performs an air conditioning operation. At this time, the control device 41 controls the opening / closing mechanism according to the cooling / heating operation to open / close the wind guide panel 20. Further, the control device 41 cleans the filter 7 by controlling the cleaning device 8 periodically or in accordance with an instruction from the user.

  As shown in FIG. 7, the opening / closing mechanism includes a moving unit 50 that moves the wind guide panel 20 close to and away from the cabinet 3 and a regulating unit that regulates the opening direction of the wind guide panel 20 when the wind guide panel 20 moves. 51.

  When opening the wind guide panel 20, the moving unit 50 moves the wind guide panel 20 in a direction away from the cabinet 3. At this time, the restricting portion 51 allows the opening of either the upper opening or the lower opening and restricts the opening of the other, thereby switching the opening direction of the wind guide panel 20. When the downward opening is restricted, the wind guide panel 20 opens upward. Conversely, when the upward opening is restricted, the wind guide panel 20 opens downward. When closing the wind guide panel 20, the moving unit 50 moves the wind guide panel 20 in a direction approaching the cabinet 3.

  That is, the restricting portion 51 restricts the opening direction by locking the upper shaft 23 or the lower shaft 22 so as not to move. When opening downward, the lower shaft 22 is locked. When opening upward, the upper shaft 23 is locked.

  Further, the restricting portion 51 has a function of holding the wind guide panel 20 in a closed posture. The closed wind guide panel 20 is close to the front panel 21 of the cabinet 3. At this time, the restricting portion 51 locks the upper shaft 23 and the lower shaft 22. Even if an external force is applied to pull the wind guide panel 20 apart, the wind guide panel 20 does not move because the shafts 22 and 23 are locked.

  As described above, a drive source only for moving the wind guide panel 20 may be provided as a drive source for opening and closing the wind guide panel 20. In addition, the drive source may be one that causes the wind guide panel 20 to perform a simple operation such as reciprocation. Therefore, the moving unit 50 for reciprocating the wind guide panel 20 can be a simple mechanism. Thereby, the opening / closing mechanism can be simplified, and the opening / closing mechanism can be downsized.

  As shown in FIGS. 9 and 10, the restricting portion 51 restricts the operation of the pair of upper and lower hooks 52 and 53 that hold the upper and lower shafts 22 and 23 and switches the opening direction by restricting the operation of the hooks 52 and 53. An interlocking unit 55 that operates the hooks 52 and 53 in an interlocked manner and a drive unit 56 that drives the interlocking unit 55 are provided. As shown in FIGS. 11 to 13, the moving unit 50 includes a rod 32 that holds the wind guide panel 20, a moving mechanism unit 57 that moves the rod 32 in and out of the cabinet 3, and a drive unit 58 that drives the moving mechanism unit 57.

  The restricting portions 51 are provided in a pair of left and right inside the cabinet 3 and are disposed on the outer side in the left-right direction with respect to the air outlet 5. As shown in FIG. 14, the restricting portion 51 is configured on the base plate 60 and unitized. The base plate 60 is fixed inside the cabinet 3.

  The upper hook 52 and the lower hook 53 are rotatably supported by a fixed shaft 61 fixed to the base plate 60. The front panel 21 is formed with doorways 21a in which the hooks 52 and 53 appear and disappear, respectively. The upper hook 52 projects from the doorway 21a and hooks the upper shaft 23 from the lower side. The upper shaft 23 is sandwiched and held by the cradle 62 and the upper hook 52 formed on the front panel 21. Similarly, the lower hook 53 protrudes from the doorway, hooks the lower shaft 22 from the lower side, and sandwiches and holds the lower shaft 22 between the lower hook 53 and the receiving base 63.

  The interlocking unit 55 enables the hooks 52 and 53 to operate using a link mechanism. Specifically, the interlocking portion 55 includes a pair of upper and lower link members 64 and 65 and an interlocking plate 66. The upper and lower link members 64 and 65 connect the upper and lower hooks 52 and 53 and the interlocking plate 66, respectively. That is, a shaft 64 a is formed at one end of the upper link member 64, and the one end shaft 64 a is fitted into the shaft hole of the upper hook 52. The upper hook 52 is rotatably supported at one end of the upper link member 64. The same applies to the lower link member 65 and the lower hook 53.

  The other end of the upper link member 64 is rotatably attached to the interlocking plate 66. The interlocking plate 66 is a sector gear, and teeth are formed on its arc surface. The interlocking plate 66 is rotatably supported by a fixed shaft 67 protruding from the base plate 60. A pair of long grooves 68 are formed in the interlocking plate 66, and the other end shafts 64 b and 65 b of the upper and lower link members 64 and 65 are fitted into the long grooves 68. Each long groove 68 extends in the radial direction about the fixed shaft 67. The other end shafts 64 b and 65 b of the link members 64 and 65 are movable in the radial direction, and play is provided by the long grooves 68.

  By the rotation of the interlocking plate 66, the link members 64 and 65 move in conjunction between the fixed shaft 61 of the hooks 52 and 53 and the fixed shaft 67 of the interlocking plate 66. As a result, the hooks 52 and 53 can rotate around the fixed shaft 61.

  The drive unit 56 includes a plurality of gears 69 and a restriction motor 70. A restriction motor 70 is provided on the mounting table 71 attached to the base plate 60. A gear 69 is fitted on the motor shaft of the restriction motor 70, and the driving force of the restriction motor 70 is transmitted to the interlocking plate 66 via the plurality of gears 69. When the regulation motor 70 is driven, the interlocking plate 66 rotates around the fixed shaft 67.

  As illustrated in FIG. 10, the switching unit 54 guides the movement of the other end shafts 64 b and 65 b of the link members 64 and 65. A restriction groove 72 is formed in the mounting table 71, and the other end shafts 64 b and 65 b are fitted into the restriction groove 72. The movement of the hooks 52 and 53 is determined by the movement of the link members 64 and 65 differently by the restriction groove 72. That is, when one hook 52, 53 moves, the other hook 52, 53 is restricted and does not move. The switching unit 54 determines the movement of the hooks 52 and 53 according to the opening direction.

  The regulation groove 72 is formed in a substantially U shape. The restriction groove 72 includes three grooves, that is, an upper lock groove 72a, a neutral groove 72b, and a lower lock groove 72c, and the three grooves are continuously connected. The upper lock groove 72 a is formed along an arc centered on the one end shaft 64 a of the upper link member 64. The lower lock groove 72 c is formed along an arc centered on one end shaft 65 a of the lower link member 65. The neutral groove 72 c is formed along an arc centered on the fixed shaft 67 of the interlocking plate 66.

  As shown in FIGS. 9 (a) and 10 (a), when the other end shafts 64b and 65b are provided in the neutral groove 72b, the hooks 52 and 53 hold the vertical shafts 22 and 23, respectively. , 23 are locked. This state is the initial state. As shown in FIGS. 9B and 10B, when the upper link groove 64 has the other end shaft 64b of the upper link member 64, the upper hook 52 holds the upper shaft 23 and the upper shaft 23 is locked. Is done. The lower hook 53 is detached from the lower shaft 22. 9 (c) and 10 (c), when the other end shaft 65b of the lower link member 65 is in the lower lock groove 72c, the lower hook 53 holds the lower shaft 22 and the lower shaft 22 is locked. Is done. The upper hook 52 is detached from the upper shaft 23.

  When the interlocking plate 66 rotates clockwise in the initial state, the other end shaft 64b of the upper link member 64 moves along the upper lock groove 72a. The other end shaft 64b of the upper link member 64 moves in the circumferential direction around the one end shaft 64a. Since the upper link member 64 does not move in the radial direction, the one end shaft 64a also does not move. Therefore, the upper hook 53 does not rotate. On the other hand, the other end shaft 65b of the lower link member 65 moves along the neutral groove 72b. The one end shaft 65a is pulled and moved. The lower hook 53 rotates clockwise. Accordingly, as shown in FIGS. 9B and 10B, the lower shaft 22 is unlocked. When the interlocking plate 66 rotates counterclockwise in the initial state, the upper shaft 23 is similarly unlocked as shown in FIGS. 9 (c) and 10 (c). Note that the control device 41 drives the left and right regulating motors 70 so that the above operation is synchronized in the left and right regulating units 51. The regulating motor 70 uses a stepping motor and is rotated forward and backward depending on the opening direction.

  The moving unit 50 is provided in a pair of left and right inside the cabinet 3 and is disposed on the outer side in the left-right direction than the restricting unit 51. As shown in FIGS. 11 to 13, the front end of the rod 32 protrudes outward from a vertically long hole 21 b (see FIG. 3) formed in the front panel 21. A support shaft 80 for attaching the rod 32 is provided on the support member 31. The front end of the rod 32 is rotatably supported by the support shaft 80. The support shaft 80 is eccentrically positioned closer to the front side than the center in the front-rear direction. The rod 32 has a circular cross section. When the wind hits, it becomes easy for the wind to flow along the surface, so that it is hard to condense even if cold wind is blown. Further, the rod 32 has a hollow structure. As a result, the weight can be reduced while maintaining the strength, and the load on the motor that moves the rod 32 can be reduced.

  The movement mechanism unit 57 moves the front end of the rod 32 forward when opening the wind guide panel 20 and moves backward when closing the wind guide panel 20. The moving mechanism unit 57 is a moving plate 81 that holds the rod 32 and reciprocates. As shown in FIG. 15, the moving plate 81 is formed in a fan shape and is rotatably supported by a fixed shaft 83 fixed to the base plate 82. The base plate 82 is fixed with respect to the cabinet 3.

  The moving unit 50 is also unitized in the same manner as the regulating unit 51. Here, the restricting portion 51 and the moving portion 50 are arranged side by side in the left and right spaces of the cabinet 3. If both are made into one unit, it can be handled as an opening / closing mechanism unit, and attachment work becomes easy. Moreover, since the moving part 50 can be comprised with few components, size reduction and thickness reduction of a unit are realizable. As a result, the opening / closing mechanism can be accommodated in a limited space, and the width of the outlet 5 can be increased. If it becomes the big blower outlet 5, the ventilation range of the width direction will become wide, and it can deliver a wind to every corner of a room.

  The rear end of the rod 32 is rotatably attached to the vicinity of the front end of the moving plate 81 via a rotation shaft 84. An arc groove 85 is formed in the moving plate 81. The arc groove 85 is formed on an arc centered on the fixed shaft 83. A rack is formed in the arc groove 85. The drive unit 58 includes an opening / closing motor 86 and a gear 87 attached to the motor shaft. The gear 87 is inserted into the arc groove 85 and meshes with the rack.

  When the opening / closing motor 86 is driven, the moving plate 81 rotates around the fixed shaft 83 as the gear 87 rotates, and the rod 32 moves in and out of the front panel 21. As shown in FIG. 11, when the wind guide panel 20 is in the closed posture, the moving plate 81 is located on the rear side. Only the front end of the rod 32 protrudes from the front panel 21. Such a state is an initial state.

  When the lower shaft 22 is unlocked and the open / close motor 86 is driven, the movable plate 81 rotates counterclockwise as shown in FIG. The rod 32 is pushed out, and the front end moves forward. The wind guide panel 20 rotates around the upper shaft 23 and opens upward. The opening / closing motor 86 is controlled so that the movable plate 81 rotates by a certain angle, for example, 50 degrees.

  When the upper shaft 23 is unlocked and the open / close motor 86 is driven, the movable plate 81 rotates counterclockwise as shown in FIG. The rod 32 is pushed out, and the front end moves forward. The wind guide panel 20 rotates around the lower shaft 22 and opens downward. At this time, since the wind guide panel 20 opens so as to be lowered, the front end of the rod 32 moves forward while gradually lowering. Also in this case, the movable plate 81 rotates by a certain angle.

  When the wind guide panel 20 is open, the open / close motor 86 is driven, and when the moving plate 81 rotates clockwise, the wind guide panel 20 is closed. As the moving plate 81 rotates, the rear end of the rod 32 moves backward. The rod 32 is drawn into the cabinet 3. Along with this, the wind guide panel 20 rotates around the upper shaft 23 or the lower shaft 22. The wind guide panel 20 approaches the cabinet 3 and takes a closed posture.

  The control device 41 drives the left and right opening / closing motors 86 so that the above operation is synchronized in the left and right moving units 50. The opening / closing motor 86 uses a stepping motor and is rotated forward and backward according to the opening / closing.

  During the air conditioning operation, when the wind guide panel 20 is open, one of the vertical shafts 22 and 23 is locked in the wind guide panel 20. Here, when the wind guide panel 20 is pulled and an external force is applied, one of the shafts (here, the upper shaft 23) is pushed. When the upper shaft 23 is pushed, the upper hook 52 tries to rotate counterclockwise. The upper link member 64 is pushed in the axial direction. The axial direction is a direction connecting one end and the other end of the upper link member 64. The other end of the upper link member 64 pushes the mounting table 71 through the restriction groove 72. At this time, the direction of the upper lock groove 72a where the other end of the upper link member 64 is located and the axial direction of the upper link member 64 are substantially orthogonal. Due to the mounting table 71 being fixed, the upper link member 64 does not move in the axial direction. The direction in which the force from the upper link member 64 acts is substantially orthogonal to the direction of the upper lock groove 72a. A force in a direction parallel to the direction of the upper lock groove 72 a does not act on the other end of the upper link member 64. Thereby, the upper link material 64 does not move along the upper lock groove 72a, and the rotation of the upper hook 52 is prevented.

  Therefore, even when an external force is applied when the air guide panel 20 is open, the locks can be prevented from being released by making the directions of the link members 64 and 65 and the restriction groove 72 orthogonal to each other. Therefore, it is possible to avoid a situation in which the open air guide panel 20 is supported by the rod 32 and hangs.

  By the way, when the wind guide panel 20 is opened to the maximum, the movement amount of the rod 32 is constant regardless of the opening direction. However, since the position of the front end of the rod 32 with respect to the wind guide panel 20 is eccentric, the opening angle is different between the upper opening and the lower opening as shown in FIGS. The opening angle when opening upward is larger than the opening angle when opening downward. That is, the closer the distance from the center to the fulcrum when opening, the greater the opening angle. The center is the upper shaft 23 or the lower shaft 22, and the fulcrum is the position of the front end of the rod 32. Since the rod 32 is attached near the upper shaft 23, the opening angle of the upper opening is large and the opening angle of the lower opening is small.

  During cooling operation, it opens downward, but if the opening angle is large, the wind guide panel 20 is lowered below the horizontal line. With this, the cold air flows in the horizontal direction, and no air flow toward the ceiling occurs. The reach of cold air is shortened, and cold air hits people directly. Therefore, in the case of downward opening, it is desirable to reduce the opening angle. During heating operation, it opens upward, but if the opening angle is small, the outlet of the hot air becomes narrow. The warm air that has returned to the wind guide panel 20 has no escape, collides with the blown warm air, and the flow is disturbed. As a result, the wind speed blown out toward the floor surface is weakened, and the hot air does not reach the floor surface.

  In this way, efficient air blowing cannot be performed during the cooling / heating operation, and the ability cannot be maximized. However, as described above, by increasing the opening angle of the upper opening and decreasing the opening angle of the lower opening, the cooling air can be blown out toward the ceiling during the cooling operation, and the hot air outlet is opened during the heating operation. It becomes wider and a smooth hot air flow can be formed. Therefore, the maximum capacity of the air conditioner can be exhibited without regret.

  In the air conditioner, the cooling / heating operation is performed according to an instruction when the user operates the remote controller or when a timer setting time is reached. The control device 41 controls the refrigeration cycle 40 and also controls the opening and closing of the wind guide panel 20 and the auxiliary louver 800. At this time, the control device 41 links the moving unit 50 and the regulating unit 51.

  When the air conditioning operation is performed, the control device 41 turns on and off the driving of the restriction motor 70 and the opening / closing motor 86 according to a predetermined timing. Also, the driving of the louver motor 803 of the auxiliary louver 800 is turned off. That is, each motor 70, 86, 803 is sequence-controlled.

  The operation timing of the auxiliary louver 800 rotates after the wind guide panel 20 is opened, and closes and rotates the auxiliary louver 800 prior to the closing operation of the wind guide panel. At the time of rapid cooling, the wind guide panel 20 once takes an upward opening posture around the upper shaft, and then switches to a lower opening posture around the lower shaft through a closing posture. At this time, the auxiliary louver 800 is The sequence control is performed so that the air guide panel 20 is opened after the air guide panel 20 is opened, and is closed and rotated before the air guide panel 20 is closed.

  Further, the control device 41 performs an initial operation prior to the start of operation. That is, the control device 41 determines the position of the wind guide panel 20 when the operation is stopped, and operates the moving unit 50 and the regulating unit 51 so as to be in the initial state as the initial operation when not in the initial state. At the start of operation, when in the initial state, the operation is started without performing the initial operation. The initial state is when the wind guide panel 20 is in the closed position, and the opening angle of the wind guide panel 20 and the states of the members of the moving unit 50 and the regulating unit 51 are related.

  As shown in FIG. 11, a position detection sensor 90 for detecting the position of the wind guide panel 20 is provided in the moving unit 50. The position detection sensor 90 is provided on the left and right moving units 50. The position detection sensor 90 is a limit switch. The position detection sensor 90 is attached to the base plate 82 of the moving unit 90 in the cabinet 3. The position detection sensor 90 is disposed so as to be close to the moving plate 81 in the initial state. When in the initial state, the rod 32 attached to the moving plate 81 contacts the position detection sensor 90. Therefore, the position detection sensor 90 detects that the wind guide panel 20 is in the initial state, that is, in the closed posture.

  Note that the position detection sensor 90 may directly detect the position of the wind guide panel 20, and is not limited to a contact sensor such as a limit switch, and may use a non-contact sensor such as an optical sensor or a camera.

  The control device 41 determines whether or not it is in the initial state based on the detection signal of the position detection sensor 90. Normally, when the operation is stopped, the wind guide panel 20 is in a closed posture, and the moving unit 50 and the regulating unit 51 are in an initial state. However, for some reason, when not in the initial state, the control device 41 determines that it is not in the initial state based on the detection signal from the position detection sensor 90. Therefore, the control device 41 performs an initial operation and forcibly sets the initial state.

  Conventionally, the time from when the wind guide panel 20 is in the most open state to the closed state (initial state) is stored as an initialization time, and during the initialization time at the start of cooling or heating operation, the wind guide panel is stored. After the initial operation of closing 20 is always performed, normal operations such as cooling and heating are performed. However, in such a conventional initial operation, the initial operation is always performed during the initialization time even when the operation is in the initial state such as the cooling operation or the heating operation, so that the normal operation of the cooling operation or the heating operation is performed. It took time to move.

  By providing the position detection sensor 90 as in the present embodiment, it is possible to detect whether or not the wind guide panel 20 is in the initial state at the start of operation, so that the wind guide panel 20 is in the initial state at the start of operation. In this case, the cooling operation and the heating operation can be performed without performing the initial operation.

  Further, when the wind guide panel 20 is not in the initial state at the start of operation, the initial operation is performed, and when the position detection sensor 90 detects that it is in the initial state, the initial operation is terminated and the cooling operation or the heating operation is started. be able to. In addition, the initial operation is performed even when the wind guide panel 20 is not in the most open state but in a slightly open state or a state where the wind guide panel 20 is opened to the middle, but when the position detection sensor 90 detects that it is in the initial state, the initial operation is performed. Since the operation is terminated, it is possible to shift to the cooling operation or the heating operation without performing the initial operation during the initialization time.

  As described above, the time required for the initial operation can be reduced by using the detection result from the position detection sensor 90, and the normal operation can be promptly started. If the position detection sensor 90 has not detected that the wind guide panel 20 is in the initial state, the opening operation of the wind guide panel 90 is not performed, but only the closing operation is performed.

  If the position detection sensor 90 does not return to the initial state after the initial operation is performed for a predetermined time, the wind guide panel 20 is once fully opened (mostly the wind guide panel is opened) (closed). The auxiliary louver may be closed, and then the wind guide panel 20 may be closed, by performing an opening operation for a time required to change from the state to the fully open state). Even if this operation is performed, if the position detection sensor 90 cannot detect that the wind guide panel 20 is in the initial state, an error is displayed as an operation failure.

  In addition, when the outlet of the air conditioner is connected to the commercial power supply for the first time, or when the energization of the air conditioner is temporarily interrupted due to a power failure or the like, the auxiliary louver 800 needs to be closed, The wind guide panel 20 is opened until at least the auxiliary louver 800 can be rotated (for example, the wind guide panel 20 is opened until the auxiliary louver 800 is fully opened), the auxiliary louver 800 is closed, and then the wind guide panel 20 is set to the initial state. To do.

  In the initial state, in the moving unit 50, as shown in FIG. 11, the moving plate 81 is at the rear position. In the restricting portion 51, as shown in FIGS. 8 and 10 (a), the other end shafts 64b and 65b of the upper and lower link members 64 and 65 are positioned in the neutral groove 72b.

  When the heating operation is started, the control device 41 first drives the regulation motor 70 of the regulation unit 51. By this driving, the interlocking plate 66 rotates clockwise. The upper link member 64 rotates around one end. The lower link member 65 is pulled up by the other end shaft 54b of the lower link member 65 moving along the neutral groove 72b. The lower hook 53 rotates clockwise, and the lower shaft 22 is unlocked.

  The control device 41 drives the opening / closing motor 86 of the moving unit 50 with a slight delay from the activation timing of the regulation motor 70. The start timing of the opening / closing motor 86 is after the lower hook 53 is separated from the lower shaft 22. That is, the control device 41 stops the restriction motor 70 when the predetermined first timing is reached. As shown in FIG. 10B, the first timing is a timing determined according to the time until the other end shaft 64b of the upper hook member 64 reaches the end of the upper lock groove 72a. After stopping the regulation motor 70, the control device 41 drives the opening / closing motor 86.

  By driving the opening / closing motor 86, the moving plate 81 rotates counterclockwise. The rod 32 is pushed forward, and the wind guide panel 20 moves in a direction away from the cabinet 3. The wind guide panel 20 opens around the upper shaft 23. When the set opening angle is reached, the control device 41 stops the opening / closing motor 86. The opening angle is calculated from the number of steps of the opening / closing motor 86.

  The control device 41 drives the open / close motor 86 for a predetermined time, and stops the open / close motor 86 at the second timing. At this time, the maximum opening angle as shown in FIG. 12 is reached. The wind guide panel 20 is in an upwardly open posture, and warm air is blown out toward the floor surface.

  Thereafter, the control device 41 controls the operation of the louver motor 803, opens the auxiliary louver 800 to a predetermined angle, and blows warm air toward the floor.

  Also in the cooling operation, the control device 41 controls the restriction motor 70 and the opening / closing motor 86 at the same timing. However, the regulation motor 70 is rotated in the opposite direction to that during the heating operation. The opening / closing motor 86 is rotated in the same direction.

  The opening / closing motor 86 stops at the second timing when it is driven for a certain time. At this time, the maximum opening angle as shown in FIG. 13 is reached. The wind guide panel 20 is in a downward opening posture, and cold air is blown out toward the ceiling. Thereafter, the control device 41 controls the operation of the louver motor 803, causes the auxiliary louver 800 to be oriented in parallel with the flow of the wind, and blows the cool air toward the ceiling.

  When the air conditioning operation is finished, the control device 41 first operates the louver motor 803 to close the auxiliary louver 800. Next, the opening / closing motor 86 is driven. The rod 32 is pulled back and the wind guide panel 20 approaches the cabinet 3. The control device 41 stops the opening / closing motor 86 when the predetermined third timing is reached. At this time, as shown in FIG. 11, the air guide panel 20 is in a closed posture, and the moving plate 81 is in the rear position. That is, the third timing is a timing determined according to the time when the movable plate 81 returns to the initial state. The position detection sensor 90 detects that the movable plate 81 has returned to the initial state. The third timing may be in accordance with this detection timing.

Thereafter, the control device 41 drives the restriction motor 70. For example, when heating operation is performed, the state changes from the state shown in FIG. 10B to the state shown in FIG.

The second embodiment is different from the first embodiment, and other configurations are the same as those of the first embodiment.

  In this embodiment, as shown in FIGS. 26 and 27, an ion generator 920 is attached to the back surface of the lower end portion of the air guide panel 20 so that the ion generator 921a is exposed, and is opposed to the ion generator 921a. Thus, a guide plate 891 as a guide means is arranged at a constant interval.

  In the above configuration, when the wind guide panel 20 is in the upwardly open posture, the ion generator 920 is positioned at the tip of the wind guide panel 20 as shown in FIG. Then, the wind guide panel 20 is inclined with respect to the wind W0 blown forward from the blowout port 5. The guide plate 891 protects the ion generator 921a from being directly exposed to the wind W0, and the wind W0 hitting the wind guide panel 20 upstream of the guide plate 891 changes the wind direction in the ventilation path 892. The ions generated in the air passage 892 are pushed out downstream along the surface of the auxiliary louver (lower member).

  The wind W1 containing ions derived from the ventilation path 892 merges with the wind W2 whose direction of wind has been changed on the surface of the guide plate 891 or the surface of the lower member 805, and efficiently puts positive and negative ions on the wind W2 far away. It becomes possible to release.

  On the other hand, when the wind guide panel 20 is in the downward-opening position, as shown in FIG. 27, the ion generator 920 is located at the rear end of the wind guide panel 920, and the back surface and the guide plate of the wind guide panel 20 Since 891 is oriented in parallel with the flow of the wind W0, the wind W0 is introduced into the ventilation path 892 without being blocked by the guide plate 891, and acts to guide the air blown out from the blowout port 5 together with the ions far away.

In addition, this invention is not limited to the said embodiment, Of course, many corrections and changes can be added to the said embodiment within the scope of the present invention. For example, at least one louver of a group of louvers made up of a plurality of louvers installed at the air outlet of a conventional air conditioner can be used as a wind direction changing plate as used in the present invention, and an ion generator and guide means can be provided. It is.
The ion generating element may generate only negative ions or only positive ions. Alternatively, an ozone generating element may be used.

  In addition, as an air conditioner, the embodiment describes using a separate air conditioner, but it is applied to a wind direction change plate of an air cleaner, a wind direction change plate of a cold air fan that blows cold air using heat of vaporization, and the like. It is also possible to do.
