Description

  The present invention relates to an air conditioner in which the suction port of a cabinet can be opened and closed.

  In the indoor unit of the air conditioner, a heat exchanger and a fan are installed in a cabinet in which an inlet and an outlet are formed. A wind guide panel is provided at the outlet, and the outlet is opened and closed. Here, an open / close panel covering the front suction port is provided so as to be openable / closable so that the suction port can not be seen from the front. During operation, the open / close panel moves and the suction port is opened.

  The opening and closing mechanism of the opening and closing panel includes, for example, a drive motor, a reduction mechanism, a drive gear meshing with the reduction mechanism, a drive shaft connected to the drive gear, and a link mechanism connected to the drive shaft. A plurality of link mechanisms are provided along the longitudinal direction of the opening and closing panel. A drive gear provided on the opening and closing panel is connected to the drive gear on one side in the longitudinal direction.

  In the case of a long opening and closing panel, if the torsional strength is insufficient, the weight of the panel may cause twisting. If twisting occurs when the opening and closing panel is open, the degree of opening differs at the left and right of the opening and closing panel in the longitudinal direction, the opening and closing panel becomes distorted, and the appearance becomes worse. Therefore, in the air conditioner described in Patent Document 1, the link mechanism near the drive gear is configured to operate later than the link mechanism far from the drive gear, so that no difference occurs in the opening on the left and right of the open / close panel Ru.

JP, 2008-261533, A

  If there are a plurality of link mechanisms in the longitudinal direction of the opening and closing panel, when the opening and closing panel is closed, a difference occurs in the operation of the left and right link mechanisms in the longitudinal direction of the opening and closing panel. Therefore, when the opening and closing panel is closed, the gap between the opening and closing panel and the cabinet becomes uneven on the side close to the drive gear and on the side far from the drive gear, the opening and closing panel becomes inclined in the longitudinal direction, and the appearance becomes worse. In order to eliminate such non-uniformity in the gap, it is conceivable to add an auxiliary driving force, for example, a biasing force of a spring, to further move the closed open / close panel to the closed position. However, when the opening and closing panel is opened, the torque of the drive motor must be increased.

  An object of this invention is to provide the air conditioner which can open and close an opening-and-closing panel so that an uneven movement may not arise to the left-right both sides of a longitudinal direction in view of the above.

  In the present invention, a heat exchanger and a fan are installed in a cabinet having a suction port and a blowout port, and an open / close panel for opening and closing the suction port, a moving body for holding the open / close panel and moving it relative to the cabinet And a drive unit for providing a driving force for moving the opening and closing panel to the body. The movable body and the drive unit are disposed longitudinally in the center of the opening and closing panel, and the movable body holds the longitudinal center of the opening and closing panel.

  Even if the left and right sides in the longitudinal direction of the opening and closing panel are uneven, the center in the longitudinal direction becomes the center of the movement of the opening and closing panel. The opening and closing panel pivots about an axis for opening and closing, or translates with respect to the cabinet. When the opening and closing panel opens and closes, the driving force is reliably transmitted to the moving body, and the movement of the opening and closing panel can be performed stably.

  The cabinet is provided with a support panel movably supporting the opening and closing panel so as to be separated from the cabinet, the drive unit is provided in the cabinet, and the movable body is provided in the support panel and connected to the drive unit .

  The support panel is pivotally held or releasably held with respect to the cabinet. Since the opening and closing panel moves with respect to the support panel, the connection between the movable body and the drive unit does not move during movement of the opening and closing panel. Therefore, the driving force can be transmitted stably.

  The support panel is openably attached to the cabinet and the support panel is secured to the cabinet as the access panel moves. Since the positional displacement of the movable body provided on the support panel can be prevented, the connection between the movable body and the drive unit is maintained during the movement of the opening and closing panel.

  A fixed part is provided which holds the connection between the movable body and the drive part when the opening and closing panel moves, and the fixed part is arranged near the drive part. The fixing portion fixes the support panel to the cabinet near the drive portion, whereby the position of the connecting portion between the moving body and the drive portion does not shift.

  When the opening and closing panel is closed, a space is provided so that the longitudinal center of the opening and closing panel can move closer to the cabinet than the left and right sides. When the open / close panel is closed, the center of the open / close panel can be further moved to the cabinet side even if either the left or right side in the longitudinal direction of the open / close panel is separated from the cabinet. It can be eliminated.

  According to the present invention, even when the opening and closing panel is twisted and the left and right are in an uneven state, the driving force for opening and closing the opening and closing panel can be reliably ensured, and the opening and closing panel is moved stably. be able to.

At the left and right ends of the front lower portion of the front panel 11, receiving holes 38 for holding the holding pieces 37 are formed. When the holding piece 37 is inserted into the receiving hole 38, the pin 40 formed at the tip of the holding piece 37 is hooked on the claw 39 formed in the receiving hole 38. The lower portion of the support panel 30 is held so as not to get out of the cabinet 1.

  The open / close panel 13 is supported by the support panel 30 so as to be rotatable about the lower shaft 41. Lower shafts 41 are formed at lower portions of left and right side surfaces of the support panel 30, and lower portions of left and right side surfaces of the open / close panel 13 are fitted to the lower shafts 41. The opening and closing panel 13 is opened and closed around the lower shaft 41. The support panel 30 is opened and closed about the upper shaft 32.

  As described above, the opening and closing panel 13 is provided to be able to open and close with respect to the cabinet 1. That is, the opening and closing panel 13 is movable with respect to the cabinet 1 by moving away from or approaching the cabinet 1. In order to open and close the opening and closing panel 13, a moving body 42 for holding the opening and closing panel 13 and moving it relative to the cabinet 1, and a drive unit 43 for giving a driving force for moving the opening and closing panel 13 to the moving body 42 are provided. Be

  As shown in FIGS. 1 and 7, the movable body 42 is provided on the support panel 30 and is configured of two links 44 and 45 and a driven gear 46. The first link 44 is a pair of left and right links arranged in parallel with a gap, and the rear end of the first link 44 is rotatably attached to the support panel 30. The second link 45 is rotatably connected to the tip of the first link 44 while being sandwiched by the first link 44. The open / close panel 13 is rotatably attached to the end of the second link 45.

  The driven gear 46 is a sector gear, and is integrally provided at the rear end of the first link 44. A shaft 47 is formed on the driven gear 46, and the shaft 47 is rotatably supported by the support panel 30. The links of the first link 44 are fixed to both sides of the shaft 47, and the first link 44 and the driven gear 46 rotate integrally.

  The drive unit 43 includes a motor 50 provided in the cabinet 1 and a drive gear 51 engaged with the driven gear 46. The motor 50 is attached to the back plate 10 and hidden by a cover. The drive gear 51 is rotatably attached to the back plate 10 and connected to the motor gear via a reduction gear. When the motor 50 is driven, the drive gear 51 rotates and the driven gear 46 rotates. The driving force from the motor 50 is transmitted to the driven gear 46, and as the driven gear 46 rotates, the first link 44 and the second link 45 move, and the open / close panel 13 is opened and closed.

  The movable body 42 and the drive unit 43 are disposed at the center in the longitudinal direction with respect to the open / close panel 13. The first link 44 of the movable body 42 is disposed at the longitudinal center of the upper portion of the support panel 30, and the second link 45 holds the longitudinal center of the upper portion of the open / close panel 13. The motor 50 of the drive unit 43 is disposed at the center in the longitudinal direction of the upper portion of the cabinet 1. Thereby, a driving force acts on the center in the longitudinal direction of the opening and closing panel 13.

  When the opening and closing panel 13 is opened and closed, the support panel 30 is fixed to the cabinet 1 so that the driving force of the drive unit 43 can be reliably transmitted to the moving body 42. Then, the fixing | fixed part 55 holding the connection of the mobile body 42 and the drive part 43 is provided. The fixing portion 55 includes a hook 56 provided on the support panel 30 and a locking portion 57 provided on the cabinet 1. When the hook 56 is locked to the locking portion 57, the support panel 30 does not move relative to the cabinet 1.

  The hooks 56 are formed in the longitudinal center of the upper portion of the support panel 30, as shown in FIG. The locking portion 57 is, as shown in FIG. 5, a recess formed at the center in the longitudinal direction of the upper portion of the front panel 11, and the hook 56 can be moved in and out. This recess is surrounded on three sides by the front wall and the left and right side walls. When the hooks 56 are fitted to the locking portions 57, the hooks 56 abut on the front wall and the left and right side walls of the locking portions 57, and the forward and lateral movement of the support panel 30 is restricted.

  When the open / close panel 13 is closed, the second link 45 is folded with respect to the first link 44, and the second link 45 enters the gap of the first link 44. Also, the driven gear 46 is located at the upper corner of the support panel 30. As described above, when the opening and closing panel 13 is closed, the compact moving body 42 fits in the gap between the support panel 30 and the front panel 11. In addition, the drive unit 43 is also located at the upper front corner of the front panel 11. Therefore, a member for opening and closing the opening and closing panel 13 can be disposed in the empty space of the cabinet 1, and there is no need to provide a dedicated accommodation space in the cabinet 1, and the space in the cabinet 1 can be effectively utilized.

  When attaching the support panel 30 to the cabinet 1, the user inserts the support piece 33 into the insertion hole 35 with the support panel 30 in a horizontal state. The upper shaft 32 is fitted in the support groove 36, and the open / close panel 13 is pushed rearward while being pivoted about the upper shaft 32. The guide pin 34 is guided by the insertion hole 35 while rotating around the upper shaft 32 and moves rearward than the upper shaft 32. Further, the holding piece 37 of the support panel 30 is fitted into the receiving hole 38 of the front panel 11, and the pin 40 is hooked on the claw 39. The hook 56 is also fitted into the locking portion 57. Thus, the support panel 30 is attached to the front panel 11. At the lower part of the support panel 30, the holding piece 37 is held in the insertion hole 35. At the top of the support panel 30, the hooks 56 are held by the locking portions 57. Therefore, the support panel 30 is held so as not to move forward. In particular, the support panel 30 can be held at the longitudinal center of the upper portion of the support panel 30 so that the support panel 30 does not move in the front-rear direction.

  When the support panel 30 is opened, when the user strongly pulls the lower part of the support panel 30, the claws 39 bend and the pin 40 is released, and the holding piece 37 is removed from the receiving hole 38. The lower portion of the support panel 30 can be separated from the cabinet 1. When the support panel 30 is lifted upward as it is, the support piece 33 comes out of the insertion hole 35, and as shown in FIG. 8, the support panel 30 pivots about the upper shaft 32 and opens. When the support panel 30 is further raised upward, as shown in FIG. 11, the hooks 56 are disengaged from the locking portions 57, and the support panel 30 is removed from the cabinet 1.

  An outdoor unit (not shown) of the air conditioner includes a compressor, a four-way valve, an outdoor heat exchanger, an expansion valve, and an outdoor fan. A refrigeration cycle is formed by the compressor, the four-way valve, the outdoor heat exchanger, the expansion valve, and the indoor heat exchanger 5. And an air conditioner is provided with a control device which controls refrigeration cycle and performs air conditioning operation such as cooling operation, heating operation, dehumidifying operation and the like. The control device controls the opening and closing of the opening and closing panel 13 according to the air conditioning operation.

  When the air conditioning operation is started, the control device operates the drive unit 43 to open the open / close panel 13. When the motor 50 is driven, the driven gear 46 is rotated by the rotation of the drive gear 51. As the driven gear 46 rotates, the first link 44 pivots upward. As the second link 45 is pushed forward, it is pivoted downward, and the upper portion of the open / close panel 13 is pushed forward. The opening and closing panel 13 opens around the lower part, and the suction port 2 on the front of the cabinet 1 is exposed. At this time, the wind which is blown out from the blowout port 3 and is directed upward is blocked by the open / close panel 13 and does not reach the suction port 3 directly, thereby preventing the occurrence of a short circuit.

  When the air conditioning operation is stopped, the control device operates the drive unit 43 so as to close the opening and closing panel 13. When the motor 50 is reversely rotated, the links 44 and 45 are drawn to close the open / close panel 13. Driving of the motor 50 at the time of opening and closing is performed for a predetermined time (the number of steps).

  When the opening and closing panel 13 opens and closes, the support panel 30 is held so as not to be separated from the front panel 11. Therefore, the driven gear 46 is firmly engaged with the drive gear 51, and the drive force is surely transmitted to the links 44 and 45, so that the open / close panel 13 can be opened and closed stably. In addition, since the opening and closing panel 13 is held at one point in the center in the longitudinal direction, a twist is generated in the opening and closing panel 13, and even if the opening degree may differ between the left and right in the longitudinal direction Therefore, the driving force can be applied to the opening and closing panel 13 so that the stable opening and closing can be always performed.

  In addition, members for opening and closing such as the links 44 and 45 and the gears 46 and 51 are located in front of the suction port 2. A center frame for holding the left and right filters is provided at the center of the cabinet 1 in the longitudinal direction, and a member for opening and closing is located in front of the center frame. Therefore, when indoor air is sucked from the suction port 2, the member for opening and closing does not interfere with the suction. Further, since the members for opening and closing are provided only at the center in the longitudinal direction, the number of members for opening and closing can be reduced compared to the case where a plurality of links are provided on the left and right. Since it is not necessary to provide an opening and closing member on the opening and closing panel 13, the weight of the opening and closing panel 13 is not increased, the load on the motor 50 is reduced, and the motor 50 can be miniaturized.

Second Embodiment
When the opening and closing panel 13 is twisted, when the opening and closing panel 13 is closed, one of the left and right sides in the longitudinal direction of the opening and closing panel 13 first contacts the cabinet 1 while the other side is separated from the cabinet 1. That is, the open / close panel 13 can not be completely closed. In order to avoid such a situation, the longitudinal center of the opening and closing panel 13 can be moved further to the cabinet 1 side than the left and right sides. The other configuration is the same as that of the first embodiment.

  When the opening and closing panel 13 is closed, a space is provided so that the central portion in the longitudinal direction of the opening and closing panel 13 can move closer to the cabinet 1 than the left and right end portions. That is, as shown in FIG. 12, a concave portion 61 is formed in the central portion of the upper portion in the longitudinal direction of the support panel 30 facing the opening / closing panel 13. Thereby, a space which can move the central portion in the longitudinal direction of the opening and closing panel 13 is generated between the support panel 30 and the opening and closing panel 13.

  Then, the control device operates the motor 50 for a predetermined time which is slightly longer than a predetermined driving time. The driving time is a time until the untwisted opening and closing panel 13 closes, and the predetermined time is a time obtained by adding the time for the opening and closing panel 13 to move in the recess to the driving time.

  When the opening and closing panel 13 is closed, the longitudinal center of the opening and closing panel 13 is drawn closer to the cabinet 1 than the front surface of the support panel 30 by operating the motor 50 for a predetermined time. When the opening and closing panel 13 is twisted, one side in the longitudinal direction of the opening and closing panel 13 contacts the support panel 30 when the drive time elapses from the start of the operation of the motor 50, but the other side does not contact the support panel 30. The motor 50 is further driven without stopping. A central portion in the longitudinal direction of the upper part of the opening and closing panel 13 moves in the recess 61, and the whole opening and closing panel 13 is brought closer to the cabinet 1 side. When the predetermined time has elapsed, the motor 50 is stopped. The other side of the open / close panel 13 in the longitudinal direction also contacts the support panel 30. Thus, even if the left and right sides in the longitudinal direction of the opening and closing panel 13 are uneven, when the opening and closing panel 13 is closed, the unevenness in left and right is eliminated, and the opening and closing panel 13 is closed with no gap with the support panel 30. It can be closed.

The opening and closing panel 13 is attached to the support panel 30 so as to be openable and closable. The left and right sides of the upper portion of the support panel 30 in the longitudinal direction are provided with claws, and the front panel 11 is provided with a locking portion such as a hole for locking the claw, a protrusion or the like. The other configuration is the same as that of the first or second embodiment.

  The support panel 30 is held by the cabinet 1 on both left and right sides, and a state in which the drive gear 51 attached to the cabinet 1 and the driven gear 46 attached to the support panel 30 are engaged by further providing the fixing portion 55 Can be maintained. Therefore, the opening and closing panel 13 can be stably opened and closed.

The driven gear 46 is provided with a drive shaft parallel to the longitudinal direction, and the drive shaft is rotatably connected to the rear end of one of the left and right link mechanisms. The other configuration is the same as in the first to third embodiments.

  When the opening and closing panel 13 moves away from the cabinet 1, the suction port 2 opens. When the opening and closing panel 13 moves so as to approach the cabinet 1, the suction port 2 is closed. At this time, even if the opening and closing panel 13 is twisted, the driving force can be transmitted from the driving unit 43 at the center in the longitudinal direction to the left and right link mechanisms, and the opening and closing panel 13 can be stably opened and closed.

  As described above, in the air conditioner according to the present invention, the heat exchanger 5 and the fan 6 are installed in the cabinet 1 having the suction port 2 and the blowout port 3 and the open / close panel 13 for opening and closing the suction port 2 A movable body 42 for holding 13 and moving it with respect to the cabinet 1 and a drive unit 43 for giving the movable body 42 a driving force for moving the open / close panel 13 are provided.
