Definitions

  • the present invention relates to an air conditioner including in an indoor unit thereof a panel which is opened and closed according to cooling or heating operation.
  • a blow out port is formed on a front surface of a cabinet and warm air or cool air is blown out from the blow out port. According to a cooling or heating operation, a panel which opens and closes the blow out port opens and the direction of the blown out air is switched.
  • Patent Document 1 an air conditioner that, when detecting a position of a rotating panel to stop the rotation, stops the panel at a predetermined position.
  • returning to the initial state is generally performed regardless of the state of the panel.
  • the time of the initial operation is set longer than that for returning from the maximum opened state to the initial state so as to be able to return to the initial state reliably.
  • the panel is returned to the initial state soon when the panel is in a state close to the initial state, the panel is not opened before the lapse of a set time. Thus, wasted time is spent.
  • the present invention aims to provide an air conditioner capable of minimizing a time required for the initial operation.
  • a blow out port is formed on a front surface of a cabinet, a panel is provided for covering the front surface, the panel being capable of being opened both upwardly and downwardly with an upper or lower shaft as a center, a control apparatus which controls opening and closing of the panel according to an operation state and a position detecting sensor which detects a position at which the panel is opened are provided, and the control apparatus, when opening the panel, performs an initial operation for bringing the panel into an initial state based on a detection signal of the position detecting sensor.
  • the control apparatus device judges necessity of the initial operation by the position of the panel. That is, when the panel is in the initial state, the initial operation is not necessary. The initial operation may be performed only when being not in the initial state.
  • the control apparatus opens the panel without performing the initial operation. In this way, the position detecting sensor detects whether or not the panel is in the initial state and the control apparatus executes the initial operation when being not in the initial state is detected.
  • the control apparatus opens the panel after the position detecting sensor detects that the panel is brought into the initial state.
  • the panel is necessarily returned to the initial state. Accordingly, it is possible to open the panel in the specified direction reliably.
  • the initial state of the panel is when the panel is closed. Since the closed state of the panel may be detected, the position detecting sensor is arranged in the cabinet. Thereby, the position detecting sensor is not affected by external noise such as bungle due to an extraneous substance.
  • the panel when an operation such as cooling or heating is started, if the initial operation is not necessary, the panel is able to be opened soon, and even if the initial operation is necessary, only minimum required initial operation is required to be performed. This makes it possible to start a cooling or heating operation instantly and to provide a user with a comfortable environment.

  • a suction port 4 is formed in the upper surface of the cabinet 3, and a blow-out port 5 is formed in the curved surface.
  • An air passageway 6 extending from the suction port 4 to the blow-out port 5 is formed in the inside of the cabinet 3, and the heat exchanger 1 and the indoor fan 2 are arranged in the air passageway 6.
  • a filter 7 is arranged between the suction port 4 and the heat exchanger 1, so as to remove dust from the indoor air sucked from the suction port 4.
  • a cleaning apparatus 8 which cleans the filter 7 is provided.
  • the filter 7 is moved by the cleaning apparatus 8 in the cabinet 3 so as to pass through a dust removing section 9. Thereby, the dust adhering to the filter 7 is removed in the dust removing section 9.
  • a guide passage 10 curved in a U-shape in side view is formed on the front side in the cabinet 3, and a moving section, which is made of a motor and a gear, reciprocates the filter 7 along the guide passage 10.
  • the dust is scraped by a rotating brush 11 from the filter 7 passing through the dust removing section 9.
  • a suction fan air is made to flow in the direction substantially in parallel with the filter 7 (in the left and right direction), so that the scraped dust is sucked and discharged.

As shown in Figures 3 to 6 , the wind guide panel 20 is configured to be able to be upwardly and downwardly opened, and an opening and closing mechanism by which the wind guide panel 20 is moved to be opened and closed is provided.
  • the wind guide panel 20 is formed by one curved panel and covers the front surface of the cabinet 3.
  • the width of the wind guide panel 20 is set to be the same as the width of the cabinet 3 and is set larger than the width of the blow-out port 5.
  • a front panel 21 is formed from the middle stage portion of the front surface to the bottom surface so as to be one stage lower than the front surface.
  • a recessed section is formed over the whole width direction so that the wind guide panel 20 can be fit into the recessed section.
  • An opening is formed in the front panel 21 which forms the recessed section, and the opening serves as the blow-out port 5. Therefore, the wind guide panel 20 is located in front of the blow-out port 5, so as to cover the blow-out port 5 and the front panel 21 around the blow-out port 5. At this time, the wind guide panel 20 is held in a closed attitude as shown in Figure 2 .
  • the outer surface of the wind guide panel 20 forms 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 formed as a member which configures 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 is formed into a long panel having a total length greater than that of the louver adopted in a conventional air conditioner.
  • the wind guide panel 20 is rotated about upper and lower shafts in the different directions, so as to thereby be opened in one of the upward and downward directions.
  • the wind guide panel 20 is downwardly opened about the lower shaft 22.
  • the wind guide panel 20 is connected to the lower wall of the blow-out port 5, so that a long nozzle is formed by the wind guide panel 20 and the upper wall of the blow-out port 5.
  • the wind guide panel 20 guides the cool air in the obliquely upward direction so that the cool air is blown out toward the ceiling.
  • the wind guide panel 20 is upwardly opened about the upper shaft 23.
  • the wind guide panel 20 When held in the upwardly opened attitude, the wind guide panel 20 covers the front of the blow-out port 5 and suppresses the flow of warm air blown out toward the front so as to guide the warm air toward the floor surface. Note that also at the initial stage of the cooling operation, the wind guide panel 20 is held in the upwardly opened attitude to allow the cool air to be blown out toward the floor surface, so that the rapid cooling is performed. As shown in Figure 2 , at the non-operation time, the wind guide panel 20 is held in the closed attitude and covers the blow-out port 5 so as to be integrated with the cabinet 3.
  • a wind direction plate 24 and an auxiliary louver are provided in the blow-out port 5.
  • the wind direction plate 24 changes its angle in the left and right direction so as to change the wind direction in the left and right direction.

  • a peripheral wall for reinforcement is formed at both side edges on the inner surface of the wind guide panel 20 in the front and rear direction (short side direction).
  • the peripheral wall is formed over the whole length in the left and right direction (long side direction).
  • the peripheral wall is formed to have a hollow structure and can be thick. With such peripheral wall, the strength of the wind guide panel 20 can be increased, and the deflection of the wind guide panel 20 can be prevented.
  • the same peripheral wall for reinforcement is also formed at both side edges in the left and right direction. Therefore, the sway of the wind guide panel 20 can be prevented.

Thereby, it is possible to easily perform the control of the air blowing direction at the time when the wind guide panel 20 is opened. That is, at the time of cooling operation, cool air can be guided toward the ceiling, so as to increase the reaching distance of the cool air. At the time of heating operation, warm air is guided toward the wall so as to reach the floor surface.
  • an inclined surface is formed on the tip side of the peripheral wall.

  • the blowing range of air in the width direction can be increased, and thereby it is possible to supply the air to all corners 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 rotary shaft 84.
  • a circular arc groove 85 is formed in the moving plate 81.
  • the circular arc groove 85 is formed on a circular arc centering on the fixed shaft 83.
  • a rack is formed in the circular arc groove 85.
  • the driving section 58 is configured by an opening and closing motor 86, and a gear 87 attached to the motor shaft of the opening and closing motor 86.
  • the gear 87 is inserted into the circular arc groove 85, so as to mesh with the rack.
  • the moving plate 81 When the opening and closing motor 86 is driven, the moving plate 81 is rotated about the fixed shaft 83 according to the rotation of the gear 87, so that the rod 32 is moved into and out of the front panel 21.
  • the moving plate 81 When the wind guide panel 20 is held in the closed attitude as shown in Figure 11 , the moving plate 81 is located in the rear side. Only the front end of the rod 32 is made to project from the front panel 21. This state is the initial state.
  • the moving plate 81 When the lock of the lower shaft 22 is released, and when the opening and closing motor 86 is driven, the moving plate 81 is rotated counterclockwise as shown in Figure 12 .
  • the rod 32 is pushed out, so that the front end of the rod 32 is moved to the front side.
  • the wind guide panel 20 is rotated about the upper shaft 23, so as to be upwardly opened.
  • the opening and closing motor 86 is controlled so that the moving plate 81 is rotated by a fixed angle of, for example, 50 degrees.
  • the moving plate 81 When the lock of the upper shaft 23 is released, and when the opening and closing motor 86 is driven, the moving plate 81 is rotated counterclockwise as shown in Figure 13 .
  • the rod 32 is pushed out, so that the front end of the rod 32 is moved to the front side.
  • the wind guide panel 20 is rotated about the lower shaft 22, so as to be downwardly opened. At this time, the wind guide panel 20 is opened so as to be downwardly moved, and hence the front end of the rod 32 is also moved to the front side while being gradually downwardly moved. Also in this case, the moving plate 81 is rotated by the fixed angle.
  • the wind guide panel 20 When the wind guide panel 20 is opened, and when the opening and closing motor 86 is driven to cause the moving plate 81 to rotate clockwise, the wind guide panel 20 is closed. By the rotation of the moving plate 81, the rear end of the rod 32 is moved to the rear side. The rod 32 is drawn into the cabinet 3. Thereby, the wind guide panel 20 is rotated about the upper shaft 23 or the lower shaft 22. The wind guide panel 20 is made to approach the cabinet 3, so as to be held in the closed attitude.
  • control apparatus 41 drives the opening and closing motors 86 on the left and right sides so that the above described operations in the left and right side moving sections 50 are synchronized with each other.
  • a stepping motor is used as the opening and closing motor 86 and is normally and reversely rotated according to the opening and closing operations.
  • one of the upper and lower shafts 22 and 23 of the wind guide panel 20 is locked.
  • one of the shafts here, the upper shaft 23
  • the upper hook 52 is made to rotate counterclockwise.
  • the upper link 64 is pushed in the shaft direction.
  • the shaft direction is the direction which connects the one end and the other end of the upper link 64.
  • the other end of the upper link 64 pushes the mounting base 71 through the regulating groove 72.
  • the direction of the upper locking groove 72a, at which the other end of the upper link 64 is located, is substantially orthogonal to the shaft direction of the upper link 64. Since the mounting base 71 is fixed, the upper link 64 is not moved in the shaft direction. Further, the acting direction of the force from the upper link 64 is substantially orthogonal to the direction of the upper locking groove 72a. No force acts on the other end of the upper link 64 in the direction in parallel with the direction of the upper locking groove 72a. As a result, the upper link 64 is not moved along the upper locking groove 72a, so that the rotation of the upper hook 52 is prevented.
  • the upper shaft 23 is firmly held by the upper hook 52. For this reason, even when an external force is applied to the opened wind guide panel 20, the upper shaft 23 is not separated from the upper hook 52.
  • the wind guide panel 20 when the wind guide panel 20 is held in the closed attitude, the upper shaft 23 and the lower shaft 22 are locked and held by the hooks 52 and 53, respectively. Therefore, the wind guide panel 20 is not easily separated from the cabinet 3. Further, the wind guide panel 20 in the closed attitude is held as a part of the front panel of the cabinet 3. Thus, the wind guide panel 20 is not hooked by an external object and hence is not unexpectedly separated from the cabinet 3.
  • the upper and lower hooks 52 and 53 are mechanically connected to each other so as to be driven by the one regulating motor 70. This prevents the operation timings of the hooks 52 and 53 from being shifted from each other, so that the shafts 22 and 23 can be surely locked and opened. Therefore, the situation in which the lock of the respective shafts 22 and 23 is simultaneously released may not occur, and hence the reliability of opening and closing operation can be improved.
  • the opening angle at the time when the wind guide panel 20 is upwardly opened is different from the opening angle at the time when the wind guide panel 20 is downwardly opened.
  • the upwardly opening angle is set larger than the downwardly opening angle. That is, the opening angle is increased as the distance from the center to the fulcrum is reduced at the time when the wind guide panel 20 is opened.
  • 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 closer to the upper shaft 23, the upwardly opening angle is set large, and the downwardly opening angle is set small.
  • the wind guide panel 20 is downwardly opened at the time of cooling operation. However, when the downwardly opening angle is large, the wind guide panel 20 is set below the horizontal line. This causes the cool air to flow in the horizontal direction, and does not cause the air to flow toward the ceiling. The reaching distance of the cool air is reduced, and the cool air directly hits a person. Therefore, in the case where the wind guide panel 20 is downwardly opened, it is preferred to reduce the opening angle.
  • the wind guide panel 20 is upwardly opened at the time of heating operation. However, when the opening angle is small, the outlet of the warm air is narrowed. The warm air, which is returned after hitting the wind guide panel 20, has no place to escape, and hence collides with the blown-out warm air, so as to thereby disturb the flow of the warm air. As a result, the velocity of the air blown out toward the floor surface is reduced, so as to prevent the warm air from reaching the floor surface.
  • the cooling or heating operation is performed on the basis of an instruction generated when the user operates the remote controller, or is performed when the set time of the timer is reached.
  • the control apparatus 41 controls the refrigerating cycle 40 and the opening and closing of the wind guide panel 20. At this time, the control apparatus 41 operates the moving section 50 and the regulating section 51 in association with each other.
  • control apparatus 41 When performing the cooling or heating operation, the control apparatus 41 turns on and off the driving of the regulating motor 70 and the opening and closing motor 86 according to a predetermined timing. That is, the respective motors 70 and 86 are sequence-controlled.
  • control apparatus 41 judges whether or not to perform the initial operation prior to start of the operation. That is, the control apparatus 41 determines the position of the wind guide panel 20 at the time when the operation is stopped. When the wind guide panel 20 is not set in the initial state, the control apparatus 41 operates, as the initializing operation, the moving section 50 and the regulating section 51 so that the wind guide panel 20 is set in the initial state. When the operation is started, and when the wind guide panel 20 is set in the initial state, the control apparatus 41 starts the operation without performing the initializing operation. Note that the state in which the wind guide panel 20 is held in the closed attitude is the initial state, and that the opening angle of the wind guide panel 20 is associated with the states of the respective members of the moving section 50 and the regulating section 51.
  • a position detecting sensor 90 for detecting the position at which the wind guide panel 20 is opened is provided in the moving section 50.
  • the position detecting sensors 90 are provided in the right and left moving sections 50.
  • the position detecting sensor 90 is a limit switch.
  • the position detecting sensor 90 is attached to the base plate 82 of the moving portion 50 in the cabinet 3.
  • the position detecting sensor 90 is arranged so as to be closer to the moving plate 81 which is in the initial state. When being in the initial state, the rod 32 attached to the moving plate 81 comes in contact with the position detecting sensor 90. Accordingly, the position detecting sensor 90 detects that the wind guide panel 20 is in the initial state, that is, the closed posture.
  • the control apparatus 41 determines whether or not the wind guide panel 20 is set in the initial state. When the operation is stopped, the wind guide panel 20 is normally held in the closed attitude, and hence the moving section 50 and the regulating section 51 are set in the initial state. At this time, when being in the initial state is detected, the control apparatus 41 does not execute the initial operation.
  • control apparatus 41 judges not to be in the initial state by the detection signal of the position detecting sensor 90. Then, the control apparatus 41 performs the initial operation to bring into the initial state forcibly.
  • the initialization time period during which the wind guide panel 20 is changed from the maximum opened state (fully opened state) to the closed state (initial state) is stored as the initialization time period, and that when the cooling or heating operation is started, the initializing operation of closing the wind guide panel 20 is necessarily performed during the initialization time period, and then the normal operation, such as the cooling or heating operation, is performed.
  • the initializing operation even when the wind guide panel 20 is set in the initial state at the time of starting such operation as cooling or heating operation, the initializing operation is necessarily performed during the initialization time period, and hence it takes a time until the operation is shifted to the normal operation of cooling or heating operation.
  • the position detecting sensor 90 when the position detecting sensor 90 is provided, it is possible to detect, at the time of starting the operation, whether or not the wind guide panel 20 is set in the initial state. Thus, when the wind guide panel 20 is set in the initial state at the time of starting the operation, it is possible to perform the cooling or heating operation without performing the initializing operation.
  • the initial operation is performed, and the initial operation is finished at the time when the position detecting sensor 90 detects to be in the initial state and it is possible to shift to cooling operation or heating operation.
  • the initial operation is finished at the time when the position detecting sensor 90 detects to be in the initial state, thus making it possible to shift to cooling operation or heating operation even without performing the initial operation until reaching the initialization time.
  • the initialization time is 30 seconds
  • the position detecting sensor 90 detects to be in the initial state 15 seconds later after the initial operation is started, the initial operation is stopped to shift to a normal operation.
  • a time to perform the initial operation is made shorter by 15 seconds than in the conventional manner.
  • the opening operation of the wind guide panel 90 for performing a normal operation is not performed but only the initial operation is performed until the position detecting sensor 90 detects that the wind guide panel 20 is in the initial state.
  • the position detecting sensor 90 does not detect that the wind guide panel 20 is brought into the initial state even after the initial operation has been performed for a predetermined time, there is a possibility that the wind guide panel 20 can not be closed by the auxiliary louver (not shown) obstructing.
  • the opening operation is firstly performed only for a required time to bring into the fully opened state from the initial state so that the wind guide panel 20 is temporarily brought into the fully opened state. At this time, one of the shafts 22 and 23 which is currently held is kept held and changing of the shafts 22 and 23 to be held is not performed.
  • the auxiliary louver is brought into the closed state after the wind guide panel 20 is brought into the fully opened state. Then, the wind guide panel 20 is caused to perform the closing operation for the initialization time to be returned to the initial state. Even after performing the operation, when the position detecting sensor 90 can not detect that the wind guide panel 20 is brought into the initial state, the control apparatus 41 performs an error display as a malfunction. Note that, although the wind guide panel 20 has been in the fully opened state in the above description, it is not necessarily required to bring into the fully opened state and the wind guide panel 20 may be opened until at least the auxiliary louver becomes rotatable.
  • the wind guide panel 20 is opened until at least the auxiliary louver becomes rotatable (may be, of course, opened to the fully opened state), and after bringing the auxiliary louver into the closed state, the wind guide panel 20 is brought into the initial state.
