Description

  The present invention relates to an air conditioner in which the size of a wind guide panel changes according to the blowing direction.

  In the indoor unit of the air conditioner, an air outlet is formed on the front surface of the cabinet, and hot air or cold air is blown out from the air outlet. An air guide panel that switches the direction of the air blown in accordance with the air conditioning operation is provided in front of the air outlet. In order to control the wind direction more accurately, it is necessary to enlarge the wind guide panel. However, the size of the wind guide panel is limited by the size of the air outlet and the appearance of the indoor unit.

  In Patent Document 1, when a wind guide panel is divided into two upper and lower panels and blows obliquely upward, the two panels are integrally connected and opened, and when blowing downward, only the lower panel Is described as opening. By connecting and opening two panels, it becomes a long panel, and it becomes possible to send a wind far in the horizontal direction.

Japanese Patent No. 4921135

  In the above-described air conditioner, when the air is blown downward, the lower panel is rotated around the upper part of the blower outlet, and therefore there is no panel at the lower part of the blower outlet. Therefore, when the wind that has flowed along the inner wall of the air outlet is blown out from the air outlet, the flowing air is peeled off at the lower edge of the air outlet to generate a turbulent flow. As a result, a blowing loss occurs, the blowing efficiency is reduced, and it becomes impossible to blow far away.

  In view of the above, an object of the present invention is to provide an air conditioner that can blow air not only horizontally but also downward.

  The air conditioner of the present invention is provided with a wind guide panel that covers the blowout port of the cabinet, and the wind guide panel can be divided into upper and lower parts. When the wind guide panel is in the upper blowing state with the air outlet opened and the air blowing direction forward, the wind guide panel opens as a single panel around the lower part of the air outlet, and the air guide panel opens the air outlet and blows the air. When the air is directed downward, the wind guide panel is divided into two parts, the upper panel opens around the top of the air outlet, and the lower panel opens around the lower part of the air outlet. .

  When the wind guide panel is in the bottom blowing state, the panel is present at the lower part of the outlet. Wind separation does not occur at the lower edge of the air outlet, and the air from the air outlet is directed in a predetermined direction along the lower panel.

  In other words, the wind guide panel is composed of an upper panel and a lower panel, the upper panel is movably provided at the upper part of the blowout port, the lower panel is provided at the lower part of the blower outlet, and the lower panel is disposed at the lower part of the blower outlet. When the air guide panel is closed and the wind guide panel is closed, the upper panel and the lower panel are connected to cover the air outlet. When the air guide panel is in the upper air blow state, the upper panel is moved along with the movement of the lower panel. The wind guide panel is opened by moving away from the upper part of the windshield, and when the wind guide panel is in the bottom blowing state, the lower panel moves and opens, and the upper panel moves around the top of the outlet. And open.

  The lower panel always opens around the bottom of the outlet. When the upper panel is divided from the lower panel, the upper panel opens around the upper part of the outlet, and when the upper panel continues to the lower panel, the upper panel opens around the lower part of the outlet. As described above, the opening / closing mechanism for opening and closing the wind guide panel includes a first moving unit that moves the lower panel around the lower portion of the blower outlet, and a second movement that moves the upper panel around the upper portion of the blower outlet. And a third moving part that moves the upper panel together with the lower panel, and the third moving part moves the upper panel around the lower part of the air outlet when the wind guide panel is in the upper blowing state.

  The third moving part includes a connecting part that integrally connects the upper panel and the lower panel, and an opening / closing part that moves the upper panel connected to the lower panel around the lower part of the outlet. The connecting part includes a base member that holds and connects the upper panel and the lower panel, a lock part that holds the upper panel and the lower panel in the base member, and the upper panel and the lower panel that are held by the base member. And a release unit for releasing the state.

  The upper panel and the lower panel are connected via a base member. Since the upper panel and the lower panel are integrated with the base member, the opening / closing part moves the base member relative to the cabinet when the wind guide panel is opened / closed. In addition, a connection part is good also as a structure which connects an upper panel and a lower panel directly. The opening / closing unit may be configured to move the upper panel 11 directly, and the upper panel moves as the lower panel moves.

  The lock portion has a lock member provided on the upper panel and the lower panel, and a lock plate that locks the lock member to the base member, and the release portion relatively moves the lock member and the lock plate, The upper panel and the lower panel are made movable relative to the base member so that the upper panel and the lower panel can be separated from the base member.

  When the lock member is locked to the base member by the action of the lock plate provided on the base member, the upper panel and the lower panel are integrally held by the base member. When the release portion moves the lock member or the lock plate, the lock is released. That is, the upper panel and the lower panel can move independently from the base member.

  The lower panel is rotatably supported by the cabinet, the upper panel is rotatably supported by the base member, the base member is rotatably supported by the cabinet, and is provided on the base member so as to protrude from the cabinet. The movable body is attached, and the opening / closing section moves the movable body relative to the cabinet. As the moving body moves, the base member rotates around the lower portion of the outlet. Thereby, the upper panel and lower panel integrated with the base member open and close.

  When the wind guide panel is in the lower blowing state, the base member is fixed to the cabinet, and the upper panel and the lower panel are opened after the upper panel and the lower panel are disconnected. By fixing the base member to the cabinet, the disconnected upper panel can be moved relative to the base member. In other words, the upper panel opens and closes with respect to the cabinet around the upper part of the outlet. When the wind guide panel is closed, the upper panel and the lower panel are first closed, and then the upper panel and the lower panel are connected.

  In a state where the wind guide panel is a single panel, the tips of the two panels overlap so that there is no step. By overlapping the front ends of the panels, one panel without a gap is formed. There is no step on the panel, so the air flow is not disturbed.

  According to the present invention, by separating and opening the wind guide panel that opens as one panel in the upper blowing state, it is possible to suppress the separation of air at the edge of the outlet even in the lower blowing state, Efficient air can be blown without air loss.

When both panels 11 and 12 overlap, there is no step on the inner and outer surfaces of the wind guide panel. Thus, since the front-end | tip of each panel 11 and 12 overlaps up and down, a clearance gap cannot be made in the thickness direction of a wind guide panel. Accordingly, since there is no gap penetrating the wind guide panel, foreign matter such as dust does not enter the air outlet 6 when the wind guide panel is closed. Further, the upper panel 11 and the lower panel 12 are sequentially rotated, so that both the panels 11 and 12 can be rotated without interfering with each other.

  When the stopped air conditioner performs a heating operation, the control device 54 controls the refrigeration cycle 53 and receives an instruction for the heating operation, and at the same time, opens and closes an opening / closing mechanism so that the wind guide panel is in a down-blowing state. Make it work. The control device 54 first drives and controls the third moving unit 52 to release the connection between the upper panel 11 and the lower panel 12, and thereafter drives and controls the first moving unit 50 and the second moving unit 51 simultaneously.

  The control device 54 drives the release motor 40 of the connecting portion 20. When the release motor 40 is driven, the release arm 39 is rotated and the bearing arm 45 is simultaneously rotated. As shown in FIG. 10, the release lever 39 contacts the moving pin 38, and the lock plate 31 slides in the release direction against the urging force of the spring 37. The lock hole 36 is displaced with respect to the lock member 30, and the lock member 30 can come out of the lock hole 36. Further, the bearing arm 45 is rotated, and the upper support shaft 44 of the base member 21 is fitted into the bearing arm 45 and held. The base member 21 is fixed so as not to be detached from the cabinet 3, and the upper panel 11 is movable with respect to the cabinet 3.

  The control device 54 stops the release motor 40 when the release motor 40 is rotated by a predetermined angle. When the drive gear 43 rotates by a predetermined angle, the lock plate 31 moves a predetermined distance so that the lock with respect to the lock member 30 is completely released, and the bearing arm 45 can reliably hold the upper support shaft 44. . A predetermined angle with respect to the release motor 40 is set in advance so as to be in such a state.

  After the upper panel 11 and the lower panel 12 are disconnected, the upper panel 11 and the lower panel 12 can move independently of each other, and the base member 21 is fixed to the cabinet 3. The first opening / closing motor 60 and the second opening / closing motor 63 are driven to open the lower panel 12. At this time, due to the difference in the number of gears constituting the power transmission mechanism for the open / close motors 60 and 63, there is a time lag in the transmission of the driving force to the panels 11 and 12, so that the operation timing of the open / close motors 60 and 63 is shifted. It is. Here, the second opening / closing motor 63 is driven slightly earlier than the first opening / closing motor 60, and the upper panel 11 and the lower panel 12 start to rotate simultaneously. The open / close motors 60 and 63 may be driven at the same timing. As shown in FIG. 2, when the tip of the upper panel 11 overlaps the tip of the lower panel 12, it is preferable to drive the second opening / closing motor 63 first.

  As shown in FIG. 11, when the first opening / closing motor 60 is driven, the lower panel 12 rotates around the lower shaft 27. When the second opening / closing motor 63 is driven, the upper panel 11 rotates around the upper shaft 26. The lock members 30 of both the panels 11 and 12 come out of the base member 21, and the both panels 11 and 12 are separated from the base member 21. The upper support shaft 44 of the base member 21 is held by the bearing arm 45, and the lower portion of the base member 21 is held by the cabinet 3 via the lower shaft 27. Therefore, the base member 21 is fixed to the cabinet 3, and the base member 21 is not detached from the cabinet 3.

  When the control device 54 rotates the first opening / closing motor 60 and the second opening / closing motor 63 by the set operation angles, the control device 54 stops the opening / closing motors 60, 63. The opening angle of the upper panel 11 and the opening angle of the lower panel 12 are set according to the instructed operating conditions. The control device 54 sets an operation angle with respect to each of the open / close motors 60 and 63 according to each opening angle. The upper panel 11 and the lower panel 12 are each opened to a set opening angle and are in a lower blowing state.

  When the wind guide panel is in the lower blowing state, the lower panel 12 is located on an extension line of the lower wall that forms the outlet 6. That is, the lower edge tip of the blower outlet 6 becomes the tip of the lower panel 12, the lower edge of the blower outlet 6 is extended, and the air passage 7 extends forward. The wind flowing in the lower part of the blowout port 6 is blown out after being carried forward along the lower panel 12. Thereby, the peeling of the wind at the blower outlet 6 can be prevented, the blowing loss due to the peeling can be suppressed, and the blowing efficiency can be increased. In addition, by controlling the opening angle of each of the upper panel 11 and the lower panel 12, the blown-out wind can be reduced. The breeze thus contracted is delivered far away. Therefore, it is possible to control the wind direction downward toward the floor.

  When there is an instruction to stop the heating operation, the control device 54 performs control to stop the refrigeration cycle 53 and operates the opening / closing mechanism. In order to close the upper panel 11 and the lower panel 12, the control device 54 drives the first opening / closing motor 60 and the second opening / closing motor 63. When the open / close motors 60 and 63 rotate in the direction opposite to that when they are opened, the upper panel 11 and the lower panel 12 are closed. As each panel 11, 12 closes, the lock member 30 of each panel 11, 12 passes through the lower hole 34 of the base member 21 from the lower hole 34 to the upper hole 35 in order.

  When the open / close motors 60 and 63 are reversely rotated by the operation angle rotated when they are opened, the control device 54 stops the open / close motors 60 and 63. The upper panel 11 and the lower panel 12 are in the closed state shown in FIG. Here, the upper panel 11 is closed after the lower panel 12 is closed first so that the tip of the upper panel 11 overlaps the tip of the lower panel 12. Therefore, the control device 54 controls the operation timing of the first opening / closing motor 60 and the operation timing of the second opening / closing motor 63 in accordance with the opening angle of each panel 60, 63. The first opening / closing motor 60 stops before the second opening / closing motor 63. When the lower panel 12 stops at the closed position, the upper panel 11 closes, and the tip of the upper panel 11 comes into contact with and overlaps the tip of the lower panel 12, the upper panel 11 stops and the upper panel 11 Closed position.

  After the first opening / closing motor 60 and the second opening / closing motor 63 stop, the control device 54 drives the release motor 40. The release motor 40 rotates in the direction opposite to that when releasing the lock. As the release motor 40 rotates, the release lever 39 rotates in a direction away from the moving pin 38, and the bearing arm 45 also rotates in a direction away from the upper support shaft 44.

  As the release lever 39 rotates, the lock plate 31 slides in the lock direction by the biasing force of the spring 37. The lock member 30 comes into contact with the upper edge of the lock hole 36 of the lock plate 31, and the lock member 30 is locked to the lock plate 31. Thereby, the upper panel 11 and the lower panel 12 are integrally connected and locked to the base member 21. Further, the bearing arm 45 is separated from the upper support shaft 44.

  When the release motor 40 is rotated by a predetermined angle, the control device 54 stops the release motor 40. The upper panel 11 and the lower panel 12 return to the closed state shown in FIG.

  When the air conditioner performs the cooling operation, the control device 54 controls the refrigeration cycle 53 and operates the opening / closing mechanism so that the wind guide panel is in the upper blowing state when the cooling operation is instructed. The control device 54 drives and controls the opening / closing unit 70 so that the upper panel 11 and the lower panel 12 move in a continuous manner.

  As shown in FIG. 12, when the third opening / closing motor 72 is driven, the moving body 71 moves in a direction protruding from the cabinet 3. At this time, the upper panel 11 and the lower panel 12 are connected to each other and integrated with the base member 21. The lower panel 12 rotates about the lower shaft 27, and the base member 21 also rotates about the lower shaft 27. The upper panel 11 connected to the lower panel 12 also rotates around the lower shaft 27. That is, the upper panel 11 moves away from the air outlet 6 while moving around the lower part of the air outlet 6. When the control device 54 rotates the third opening / closing motor 72 by the set operation angle, the control device 54 stops the third opening / closing motor 72. The wind guide panel formed by connecting the upper panel 11 and the lower panel 12 opens to a set opening angle and is in an upper blowing state.

  At the time of top blowing, the upper panel 11 and the lower panel 12 are connected to form a long panel, so that a Coanda effect is obtained in which the wind flowing through the lower portion of the outlet 6 is guided forward along the long panel. As a result, it is possible to blow out the wind upward, to achieve blowing along the ceiling, and to deliver the cold wind to a distance. In addition, by using a large wind guide panel, a diffuser effect can be obtained in which the flowing wind gradually spreads and the blowing angle in the left-right direction can be widened. Thereby, the loss of the air flow is reduced and the blowing efficiency can be increased.

  As an air conditioner of the second embodiment, as shown in FIG. 14, the end surface at the lower end of the upper panel 11 and the end surface at the upper end of the lower panel 12 may be opposed to each other. A gap 80 is formed in the thickness direction of the wind guide panel between the lower end of the upper panel 11 and the upper end of the lower panel 12. When the wind guide panel changes from the closed state to the lower blowing state, the upper panel 11 and the lower panel 12 rotate independently. However, since there is a gap 80 between the upper panel 11 and the lower panel 12, the panels 11 and 12 can be rotated without interfering with each other. In addition, when the upper panel 11 and the lower panel 12 are opened and closed, any of the panels 11 and 12 may be rotated first.
