Description:
[0001]    This application claims the benefit of priority to Chinese patent application No. 201010205195.5 titled “AIR DISCHARGE STRUCTURE FOR PACKAGED AIR CONDITIONER”, filed with the Chinese State Intellectual Property Office on Jun. 18, 2010. The entire disclosures thereof are incorporated herein by reference. 
       FIELD OF THE INVENTION 
       [0002]    The present application relates to a technical field of air conditioner, and in particular, to an air discharge structure for an indoor unit of a floor standing split type air conditioner. 
       BACKGROUND OF THE INVENTION 
       [0003]    Air discharge manner of one of the prior packaged air conditioner is as fellows: the slide panel is slid upwards to open the air outlet, thereby achieving the air discharging performance, for example, a structure described in Chinese patent application No. 200810126598.3 titled “opening and closing device for an air discharge plate of a split type floor standing air conditioner”. Referring to  FIGS. 1 and 2 , in the air discharge structure of the packaged air conditioner, the upper panel  2  is driven, by the gear  3  and the rack  4 , to move upward along the lower panel  5  such that the front air outlet  7  is opened, and the fan  6  is rotated such that the generated air flow is blew out through the front air outlet  7 , thereby achieving the air supplying from the mid-upper position of the air conditioner. 
         [0004]    This kind of structure has a drawback which mainly affects the air supplying performance of the air conditioner. As shown in  FIG. 2 , affected by the structure, the segment AB of the upper panel  2  is protruded from the air conditioner body  1  where the air conditioner is in operation, thereby air can only be discharged from the mid-upper position, which limits the air discharging range of the air conditioner. To supply air from the upper portion of the air conditioner, it needs to additionally provide a top air discharge component  81 , however, the protruded segment AB will block the top air outlet  8 , resulting in an uneven air discharging. If so, not only the protruded segment AB affects the actual usage of the air conditioner, but also the structure of the air conditioner body becomes unstable. Besides, the overall appearance of the air conditioner is damaged because of the upper panel  2 , after being opened, being protruded from the air conditioner body  1 . 
       SUMMARY OF THE INVENTION 
       [0005]    In view of this, it is provided according to an object of the present application an air discharge structure for a packaged air conditioner, to facilitate increasing the air discharging range of the air conditioner. 
         [0006]    To solve the above technical problem, it is provided according to the present application an air discharge structure for a packaged air conditioner. An air conditioner body of the air conditioner is provided, at a mid-upper position thereof, with a front air outlet. An upper panel, which is slidable up and down along the air conditioner body, is mounted on the front air outlet. An upper decorative plate, which is slidable forward and backward along the air conditioner body, is mounted above the front air outlet, and a height of the upper decorative plate is matched with a travel of the upper panel. And an upper and lower position-limiting mechanism for the upper decorative plate is provided between the upper decorative plate and the air conditioner body. 
         [0007]    Preferably, a cantilever is transversely protruded from the upper panel, and a cantilever shaft is provided on the cantilever; and an oblique arm is protruded from the upper decorative plate, and the oblique arm is provided with an oblique arm groove in which the cantilever shaft can be inserted. 
         [0008]    Preferably, an oblique arm is protruded from the upper panel, and the oblique arm is provided with an oblique arm groove; and a cantilever is transversely protruded from the upper decorative plate, and a cantilever shaft, which can be inserted in the oblique arm groove, is provided on the cantilever. 
         [0009]    Preferably, the upper and lower position-limiting mechanism for the upper decorative plate includes: a position-limiting groove provided on a transverse arm which is protruded from the upper decorative plate, and a position-limiting block provided on the air conditioner body. 
         [0010]    Preferably, the upper and lower position-limiting mechanism for the upper decorative plate includes: a position-limiting groove provided on the air conditioner body, and a position-limiting block provided on a transverse arm which is protruded from the upper decorative plate. 
         [0011]    Preferably, the upper and lower position-limiting mechanism for the upper decorative plate includes: a slide rail provided on the air conditioner body, and a slide groove provided on a transverse arm which is protruded from the upper decorative plate. 
         [0012]    Preferably, the air conditioner body is provided, at a top portion thereof, with a top air outlet, and a top air discharge component for opening and closing the top air outlet is mounted on the top air outlet. 
         [0013]    Preferably, the top air discharge component is connected to the upper decorative plate. 
         [0014]    Preferably, the top air discharge component is hinged to the upper decorative plate, and the top air discharge component is hinged to the air conditioner body. 
         [0015]    Preferably, a chain and sprocket mechanism is provided between the upper panel and the air conditioner body. 
         [0016]    Compared with the prior art, in the present application, the original upper panel is divided into two parts, that is, a new upper panel and an upper decorative plate, which makes the appearance of the air conditioner more aesthetic. What&#39;s more, the new upper panel can be moved at a large travel without affecting the overall appearance, which facilitates increasing the area of the front air outlet. Further, air can be supplied from the mid-upper position in the front side and the top portion at the same time in a case that a top air outlet is provided. Thereby the air conditioner can supply air more evenly and effectively. In addition, no additional motor and gear structure are required for the structure of the top air discharge component, which can help to save the cost.

       DETAILED DESCRIPTION 
       [0027]    Hereinafter, the present application will be described in conjunction with the accompanied drawings and the embodiments. 
         [0028]      FIGS. 3 to 6  show an air discharge structure for a packaged air conditioner according to a preferred embodiment of the present application. In the air discharge structure for the packaged air conditioner, the air conditioner body  1  is provided, at a mid-upper position thereof, with a front air outlet  7 , and an upper panel  9  is mounted on the front air outlet  7 . The upper panel  9  is slidable up and down along the air conditioner body  1  through a gear-rack mechanism provided between the upper panel and the air conditioner body  1 . An upper decorative plate  10  slidable forward and backward along the air conditioner body  1  is mounted above the front air outlet  7 , and the height of the upper decorative plate is matched with the travel of the upper panel  9 , generally, they are substantially equal. Further, an upper and lower position-limiting mechanism for the upper decorative plate is provided between the upper decorative plate  10  and the air conditioner body  1 , to prevent the upper decorative plate  10  from jumping up and down during the horizontal sliding thereof 
         [0029]    Hereinafter, various parts will be described, as shown in  FIGS. 3 to 6 . 
         [0030]    A cantilever  91  is transversely protruded from the upper panel  9 , and an upper panel cantilever shaft  92  is provided on the cantilever. An oblique arm  101  is protruded from the upper decorative plate  10 , an oblique arm groove  102  is provided in the oblique arm, and the upper panel cantilever shaft  92  can be inserted in the oblique arm groove. 
         [0031]    The upper and lower position-limiting mechanism for the upper decorative plate includes: a position-limiting groove  104  provided on a transverse arm  105  protruded from the upper decorative plate  10 , and a position-limiting block  11  provided on the air conditioner body  1 . A reverse manner may be employed, that is, the position-limiting groove is provided on the air conditioner body  1  and the position-limiting block is provided on the transverse arm  105  protruded from the upper decorative plate  10 , which will not be described herein. 
         [0032]    In addition, the air conditioner body  1  is provided, at a top portion thereof, with a top air outlet  8 , and a top air discharge component  81  for opening and closing the top air outlet  8  is mounted on the top air outlet  8 . The top air discharge component  81  may be connected to the upper decorative plate  10  such that the top air discharge component  81  is driven to move where the upper decorative plate  10  is moved forward and backward. Alternatively, the top air discharge component  81  may be connected to the upper panel  9 . Or, the top air discharge component  81  may be provided independently, as soon as it is easy to be opened and closed. Apparently, additional motor and gear structure are not required for the structure of the top air discharge component  81  since it can be moved together with the upper panel  9  and/or the upper decorative plate  10 . 
         [0033]      FIG. 7  shows the action state of the top air discharge component. The top air discharge component  81  is hinged to the upper decorative plate  10 , and the top air discharge component  81  is hinged to the air conditioner body  1 . Where the upper panel  9  is moved up and down, the upper decorative plate  10  is driven to move forward and backward, thereby driving the top air discharge component  81  to move, such that the top air outlet  8  is opened or closed. 
         [0034]    Hereinafter, the operation process of the air discharge structure for the packaged air conditioner according to the present application will be described briefly. 
         [0035]    Where the air conditioner is halted: as shown in  FIG. 5 , the upper panel  9  is moved downward, the front air outlet  7  is closed, and the top air discharge component  81  and the top air outlet  8  are in a hid state as shown in  FIG. 3 . 
         [0036]    Where the air conditioner is in operation: as shown in  FIG. 6 , the upper panel  9  is driven by the gear  3  and the rack  4  to move upward. The upper decorative plate  10  is translated backward under the cooperation actions between the oblique arm groove  102  of the upper decorative plate and the cantilever shaft  92  of the upper panel as well as between the position-limiting groove  104  of the upper decorative plate and the position-limiting block  11  of the air conditioner body, to make room for the upper panel  9  such that the upper panel is moved upward continually to the state shown in  FIG. 4 . Meanwhile, the upper decorative plate  10  drives the top air discharge component  81  to move upward such that the top air outlet  8  is exposed. Since the front air outlet  7  is opened earlier, air can be discharged from the top portion and the mid-upper position in the front side of the air conditioner at the same time. 
         [0037]    Where the air conditioner finishes the operation thereof: the gear  3  and the rack  4  are rotated reversely to thereby drive the upper panel  9  to move downward and drive the upper decorative plate  10  to return to its original position, and the top air discharge component  81  is moved downward and back to the state shown in  FIG. 3 . 
         [0038]    It is to be noted that, other alternative technical solutions may be employed by the present application. Several examples are described hereinafter. 
         [0039]    Referring to  FIG. 8 , an oblique arm  94 , on which an oblique arm groove  93  is provided, is protruded from the upper panel  9 . A cantilever  107  is transversely protruded from the upper decorative plate  10 , and a cantilever shaft  103 , which can be inserted in the oblique arm groove  93 , is provided on the cantilever  107 . The operation principle and operation process thereof are as the above embodiment, and description thereof are omitted herein. 
         [0040]    Referring to  FIG. 9 , the upper and lower position-limiting mechanism for the upper decorative plate may be employed in another manner, that is, the air conditioner body  1  is provided with a slide rail  12 , and the transverse arm  105  of the upper decorative plate  10  is provided with a slide groove  106  such that the upper decorative plate  10  is slidable along the slide rail  12  forward and backward. An opposite solution may also be employed, that is, the air conditioner body  1  is provided with a slide groove, and the transverse arm  105  of the upper decorative plate  10  is provided with a slide rail. Alternatively, a pulley and slide rail cooperation manner is employed between the transverse arm  105  of the upper decorative plate  10  and the air conditioner body such that the upper decorative plate  10  is slidable forward and backward. 
         [0041]    The above embodiments are only preferable embodiments of the present application. It should be noted that, the preferable embodiments described above should not be construed as limitations to the present application, and the protection scope of the present application should be determined by the scopes defined by the claims. those skilled in the art can also make improvements and modifications without departing from the principle of the present application, and these improvements and modifications should also be deemed to fall into the protection scope of the present application.
