Detailed implementation manners

[0045] During the process of the air conditioner being updated, it is necessary to redesign the air conditioner 100, which results in the need to re-open the mold in most cases. The re-opening of the mold for the air conditioner may cost millions or tens of millions of yuan, which not only affects the technological innovation of the air conditioner 100 but also increases the production cost of the air conditioner 100. Therefore, the present invention provides an air conditioner 100, in which the front half of the top cover 3 is adapted to the panel 2, and the rear half of the top cover 3 is adapted to the rear shell 1. When facing different panels 2 and rear shells 1, if only the rear shell 1 is changed, the top cover 3 can be changed to make the top cover 3 adapt to the previous panel 2 and the redesigned rear shell 1; if only the panel 2 is changed, the top cover 3 can be changed to make the top cover 3 adapt to the previous rear shell 1 and the redesigned panel 2.

[0046] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0047] Combined with Figures 1 to 21 , an air conditioner 100 according to an embodiment of the present invention includes a rear case 1, a front panel 2, and a top cover 3. The air conditioner 100 in the present invention can be a floor-standing air conditioner, a portable air conditioner, a wall-mounted air conditioner, etc.

[0048] Among them, the front panel 2 is disposed on the front side of the rear case 1. The front panel 2 and the rear case 1 enclose an installation space, and an air outlet is provided on the front panel 2. The top cover 3 includes a top plate 31, a first skirt 32, and a second skirt 33. Both the first skirt 32 and the second skirt 33 are connected to the top plate 31, and the first skirt 32 and the second skirt 33 extend along the circumference of the top plate 31. The first skirt 32 is disposed on the rear half of the top cover 3, and the second skirt 33 is disposed on the front half of the top cover 3. The first skirt 32 is configured such that the outer peripheral surface thereof is adapted to the outer peripheral surface of the rear case 1, and the first skirt 32 is connected to the rear case 1, and the second skirt 33 is connected to the front panel 2. Specifically, the rear half of the top cover 3 is adapted to the rear case 1, and the front half of the top cover 3 is adapted to the front panel 2. The rear half and the front half of the top cover 3 can cover the tops of the front panel 2 and the rear case 1, thereby protecting the installation space.

[0049] For the air conditioner 100 according to an embodiment of the present invention, the top cover 3 can be adapted to different rear cases 1 and front panels 2, thereby simplifying the design and update of the air conditioner 100 and saving costs.

[0050] In some embodiments of the present invention, compared with the prior art, the front panel 2 has been redesigned. Therefore, the top cover 3 can be adjusted to adapt to the shape of the existing rear case 1. Specifically, combined with Figures 1 to 21 , the height of the rear half of the top cover 3 relative to the top surface of the top cover 3 is greater than the height of the front half of the top cover 3 relative to the top surface of the top cover 3. In other words, the height of the first skirt 32 relative to the top plate 31 is greater than the height of the second skirt 33 relative to the top plate 31. By raising the rear half of the top cover 3, the rear case 1 can be produced and processed using existing molds, effectively improving the utilization rate of the molds and reducing the cost of the product.

[0051] In other words, by increasing the size of the rear half of the top cover 3, with the size of the rear case 1 remaining unchanged, the height of the air conditioner can be increased, thereby increasing the internal space of the air conditioner, facilitating a more reasonable arrangement of the internal components of the air conditioner, and also improving the performance of the air conditioner 100. Moreover, the increase in the height of the air conditioner can be directly achieved by using the rear case 1 in the existing technology. The rear case 1 in the existing technology can be directly used without the need for re-molding, effectively reducing or avoiding the cost of re-molding, thereby achieving the purpose of reducing costs and improving production efficiency.

[0052] In addition, in the present invention, the rear half of the top cover 3 and the rear case 1 can be connected in an up-and-down docking manner. In other words, the height of the first skirt 32 relative to the top plate 31 is greater than the height of the second skirt 33 relative to the top plate 31. At this time, by adjusting the height of the rear half of the top cover 3, with the existing rear case 1 being used, the height of the vertical air conditioner can be further increased, thereby improving the performance of the air conditioner 100.

[0053] Optionally, the upper edge of the panel 2 is higher than the upper edge of the rear case 1. This can facilitate the connection between the panel 2 and the top cover 3 more conveniently, effectively improving the stability of the panel 2 and the top cover 3, thereby enhancing the stability and structural strength of the air conditioner 100. And the appearance effect of the air conditioner 100 can be improved by covering it with the panel 2.

[0054] Optionally, in combination with Figures 1 to 3 and Figures 19 to 21 the rear half of the top cover 3 and the top of the rear case 1 are connected in an up-and-down docking manner, and the top of the panel 2 covers the front of the front half of the top cover 3. In other words, the first skirt 32 is connected to the top wall of the rear case 1 in an up-and-down docking manner, and the second skirt 33 is arranged inside the panel 2. This can facilitate the connection between the top cover 3, the rear case 1, and the panel 2, effectively improving the installation efficiency of the top cover 3. Moreover, the fitting gap between the panel 2 and the top cover 3 can be reduced, condensation water generated due to the airflow passing through the gap between the panel 2 and the top cover 3 can be reduced, and the noise can be lowered.

[0055] Optionally, in combination with Figure 3 and Figure 4 , the outer peripheral surface of the rear half of the top cover 3 is retracted by a predetermined dimension L relative to the outer peripheral surface of the rear case 1. This can better control the assembly step difference between the top cover 3 and the rear case 1, effectively avoiding the outward protrusion of the top cover 3 after assembly.

[0056] For example, during the production of an air conditioner, the top cover 3 and the rear case 1 can be formed by injection molding. Inevitably, there will be an error between the size of the molded product and the actual size during the injection molding process. Therefore, when the outer peripheral surface of the rear half of the top cover 3 is aligned with the outer peripheral surface of the rear case 1, the outer peripheral surface of the rear half of the top cover 3 may protrude from the outer peripheral surface of the rear case 1 due to production or assembly errors. Therefore, in the present invention, by retracting the outer peripheral surface of the rear half of the top cover 3, the above problems caused by molding and assembly errors can be effectively avoided. In addition, the appearance effect of the air conditioner after assembly and molding can be effectively improved.

[0057] Optionally, the predetermined dimension L is in the range of 0.3 mm to 5 mm, and the predetermined dimension L is preferably 0.5 mm. Among them, the preselected dimension can be 0.3 mm, 0.5 mm, 1 mm, 3 mm, etc. In addition, according to the actual predetermined dimension, it can also be less than 0.3 mm or greater than 5 mm. In addition, in the circumferential direction along the first skirt 32, the dimension by which the outer peripheral surface of the first skirt 32 is retracted relative to the outer peripheral surface of the rear case 1 can be the same or variable.

[0058] Optionally, in combination with Figures 8 to 17 , a screw post 34 extending downward is provided on the top cover 3, a first screw hole 301 is provided on the screw post 34, a second screw hole 101 is provided at the top of the rear case 1, and the first screw hole 301 and the second screw hole 101 are vertically opposite. The stable installation between the top cover 3 and the rear case 1 can be achieved through the cooperation of the first screw post 34 and the second screw hole 101, effectively improving the installation efficiency and structural strength of the top cover 3, thereby improving the stability of the air conditioner 100, and reducing the gap between the top cover 3 and the rear case 1, which can avoid problems such as condensation caused by air leakage, and can also improve the performance of the air conditioner 100 and reduce the noise of the air conditioner 100.

[0059] In order to further facilitate the screw connection between the top cover 3 and the rear case 1 and improve the stability and structural strength of the screw connection between the top cover 3 and the rear case 1, the present invention has redesigned the screw post 34 and the connection between the screw post 34 and the top cover 3.

[0060] Specifically, in the present invention, the lower part of the screw post 34 has a first positioning structure around the first screw hole 301, and the top cover 3 is provided with a second positioning structure around the second screw hole 101. One of the first positioning structure and the second positioning structure includes a positioning notch 302 and the other includes a positioning rib 102, and the positioning rib 102 is embedded in the positioning notch 302. Through the cooperation of the screw post 34 and the positioning rib 102, during the assembly process of the top cover 3, the cooperation of the first positioning structure and the second positioning structure can realize the pre-positioning of the screw post 34, so that the first screw hole 301 and the second screw hole 101 can be aligned, thus facilitating the screwing of the screw. After the assembly is completed, the cooperation of the first positioning structure and the second positioning structure can also play a certain positioning role on the screw post 34, thereby effectively improving the assembly stability of the top cover 3 and the rear shell 1.

[0061] Optionally, the first positioning structure includes a plurality of notches arranged around the first screw hole 301, and the second positioning structure includes a plurality of positioning ribs 102 arranged around the second screw hole 101. The plurality of positioning ribs 102 cooperate with the plurality of notches correspondingly, so as to realize the effective cooperation of the first positioning structure and the second positioning structure and improve the assembly stability of the screw post 34 and the top cover 3. Optionally, the first positioning structure includes four notches. By evenly arranging four rib positions around the first screw hole 301, four notches are formed, and the second positioning structure may include four positioning ribs 102, and the four positioning ribs 102 are respectively embedded into the four notches.

[0062] Optionally, in combination with Figure 17 , the screw post 34 is a hollow column, and the screw post 34 includes a first guiding portion 341 and a second guiding portion 342. The first guiding portion 341 is connected to the top wall of the top cover 3 and extends downward, and the second guiding portion 342 is connected to the lower end of the first guiding portion 341 and extends downward. The inner diameter of the second guiding portion 342 is smaller than the inner diameter of the first guiding portion 341. By providing the first guiding portion 341 and the second guiding portion 342, it is convenient for the screw to be quickly and stably inserted into the screw post 34 and pass through the screw post 34 to be connected to the rear shell 1, improving the stability and efficiency of the screw connection between the top cover 3 and the rear shell 1, and avoiding the assembly blockage caused by the screw inclination.

[0063] Specifically, during the process of screwing the screw, the screw is inserted into the screw post 34 from the larger first guiding portion 341, and the inner diameter of the second guiding portion 342 is smaller than the size of the first guiding portion 341, which can adjust the end position of the screw, thus facilitating the quick pairing of the screw with the second screw hole 101 on the rear shell 1.

[0064] Optionally, a positioning pin 35 extending downward is provided on the top cover 3, and a positioning hole 103 corresponding to the positioning pin 35 is provided at the top of the rear case 1. The positioning pin 35 is inserted into the positioning hole 103. Through the cooperation of the positioning pin 35 and the positioning hole 103, the stability of the assembly of the top cover 3 and the rear case 1 can be achieved, and the pre-positioning between the top cover 3 and the rear case 1 can be facilitated, effectively improving the assembly efficiency and stability of the top cover 3.

[0065] Optionally, the positioning pin 35 includes a positioning piece 351 and a reinforcing rib 352. The reinforcing rib 352 is connected to the surface of the positioning piece 351, and the reinforcing rib 352 is inserted into the positioning hole 103 together with the positioning piece 351. The reinforcing rib 352 extends from top to bottom. The surface contact fit between the positioning pin 35 and the positioning hole 103 is converted into a multi-point contact between the reinforcing rib 352 and the positioning hole 103, effectively improving the cooperation stability between the positioning pin 35 and the positioning hole 103, and facilitating the insertion of the positioning pin 35 into the positioning hole 103. In addition, the reinforcing rib 352 can also improve the structural strength of the positioning piece 351, thereby further improving the stability and connection strength of the assembly structure of the top cover 3 and the rear case 1.

[0066] Furthermore, the lower end of the reinforcing rib 352 is configured as a wedge shape whose height gradually decreases in the direction from top to bottom relative to the positioning piece 351. In this way, when the positioning pin 35 is inserted into the positioning hole 103, the wedge-shaped reinforcing rib 352 can play a certain guiding role, effectively improving the cooperation accuracy between the reinforcing rib 352 and the positioning hole 103 and improving the assembly efficiency of the top cover 3. Further, when multiple positioning pins 35 are provided on the top cover 3 to connect the rear case 1, the dimensional errors between the multiple positioning pins 35 can also be offset by the guiding action of the wedge-shaped structure, further improving the assembly efficiency and the stability after assembly of the top cover 3 and the rear case 1.

[0067] Optionally, in combination Figures 8 to 17 , a support platform 36 is provided on the top cover 3, the positioning pin 35 is provided on the support platform 36, and the support platform 36 is vertically opposite to the periphery of the positioning hole 103. In this way, after the assembly is completed, the support platform 36 can provide a supporting effect for the top cover 3. When there is an external force acting on the top cover 3, the support platform 36 will provide a reaction force to the top cover 3, thereby improving the structural strength and stability of the top cover 3 through the support platform 36.

[0068] In addition, in some embodiments of the present invention, a support platform 36 is provided on the top cover 3, and the support platform 36 is vertically opposite to the top of the rear case 1. Thus, when a downward force acts on the top cover 3, the support platform 36 can provide support for the top cover 3, effectively improving the stability of the top cover 3.

[0069] Combined with the foregoing embodiments, a plurality of support platforms 36 are provided on the top cover 3, and the foregoing positioning pins 35 are provided on at least a part of the plurality of support platforms 36. Among them, the positioning pins 35 can be provided on all the support platforms 36, or some of the support platforms 36 can be selectively provided with the positioning pins 35. In addition, the foregoing screw columns 34 can also be provided on the support platforms 36.

[0070] In addition, when the positioning pin 35 is provided on the support platform 36, the projection of the positioning pin 35 should be smaller than the support surface of the support platform 36. Optionally, after the top cover 3 and the rear shell 1 are assembled, the support surface of the support platform 36 can support on the rear shell 1, or the support surface of the support platform 36 and the rear shell 1 can be spaced apart by a predetermined distance in the vertical direction.

[0071] Optionally, the rear shell 1 includes an outer shell 11 and a connecting portion 12. The outer shell 11 extends in the vertical direction. The connecting portion 12 is provided on the inner peripheral surface of the upper end of the outer shell 11, and the upper edge of the outer shell 11 is higher than the connecting portion 12. Among them, the rear half of the top cover 3 is connected to the connecting portion 12. Thereby, the connection between the top cover 3 and the rear shell 1 can be facilitated, and the connection efficiency and connection stability between the top cover 3 and the rear shell 1 can be improved.

[0072] Optionally, the upper edge of the panel 2 is configured in a straight-up form in the vertical direction. That is to say, the whole of the panel 2 is arranged in a form extending in the vertical direction. The upper edge of the panel 2 is arranged as a straight surface extending in the vertical direction, and the outer surface of the upper edge of the panel 2 is flush with the outer surface of the middle section of the panel 2.

[0073] Optionally, the upper edge of the panel 2 can also be configured in a shape that gradually contracts from bottom to top. That is to say, the upper edge of the panel 2 is configured in a flared form. In this way, the appearance of the air conditioner 100 can be made beautiful, and the structural stability of the air conditioner 100 can be conveniently improved.

[0074] Optionally, the outer peripheral surface of the second skirt can be set in a form adapted to the shape of the panel. For example, when the upper edge of the panel is set in a straight-up form in the vertical direction, the outer peripheral surface of the second skirt is also set as a straight surface extending in the vertical direction; when the outer peripheral surface of the second skirt is set in a shape that contracts from bottom to top, the outer peripheral surface of the second skirt is also set in a shape that contracts from bottom to top.

[0075] Optionally, a plurality of positioning grooves 303 for robot clamping are provided on the top surface of the top cover 3. Therefore, in the production and assembly process, the production and assembly of the top cover 3 can be realized by the robot clamping the positioning grooves 303, thereby facilitating the automated assembly of the air conditioner 100 and improving the assembly efficiency of the air conditioner 100.

[0076] Optionally, the panel 2 is a metal panel 2, which can improve the aesthetic effect and structural strength of the air conditioner 100, facilitate the improvement of the molding efficiency of the air conditioner 100, and reduce the production cost of the air conditioner 100.

[0077] In addition, compared with injection molding, the metal panel 2 has better molding efficiency and lower mold cost. By means of the top cover 3 described above in the present invention, the rear half of the top cover 3 is set to be adapted to the rear case 1, and the front half of the top cover 3 is set to be adapted to the panel 2, so that the rear case 1 and the mold of the rear case 1 in the prior art can be utilized, thereby reducing the production cost of the air conditioner 100. For example, after the size and shape of the panel 2 are redesigned, since the rear half of the top cover 3 is adapted to the rear case 1, the rear case 1 in the prior art can be utilized, thus saving the cost of re-opening the mold for the rear case 1 and reducing the production cost of the air conditioner 100.

[0078] Combined with the foregoing embodiments, in the present invention, the height of the rear half of the top cover 3 relative to the top surface of the top cover 3 can be increased to adjust the top cover 3 to be adapted to the panel 2 and the rear case 1. In this way, the molding cost of the top cover 3 can be further reduced, and thus the cost of the air conditioner can be further reduced.

[0079] Optionally, the top cover 3 is integrally injection molded, which can improve the molding efficiency of the top cover 3, and can improve the structural strength and stability of the top cover 3, thereby effectively improving the connection strength between the top cover 3 and the panel 2 and the rear case 1. In addition, the sealing performance of the top cover 3 can be improved, preventing external dust, water, etc. from entering the installation space through the top cover 3, reducing the leakage of cold or heat inside the air conditioner 100, effectively improving the performance of the air conditioner 100, reducing condensate water and improving the noise reduction effect.

[0080] The present invention provides a top cover 3, which has a front half and a rear half, and the height of the rear half is increased relative to the structure of the conventional top cover 3, so that the rear case 1 can borrow the existing mold, thereby improving the utilization rate of the mold and reducing the product cost.

[0081] The top cover 3 in the present invention is divided into two parts, the front half is matched with the panel 2, and the rear half is matched with the rear case 1, and the rear half is higher than the front half. The top cover 3 has a glue inlet, a manipulator picking part (positioning groove 303), a screw fixing part (screw post 34), a decorative strip buckling part. Inside the top cover 3, there are positioning ribs 102, a support platform 36, and several annular + circular reinforcing parts. The periphery of the top cover 3 has a turned-up skirt.

[0082] During the fixed assembly with the rear case 1, the four positioning ribs 102 achieve front-back, left-right guiding and positioning, and are fixedly connected to the box body through four evenly distributed screws at the top. Among them, the support platforms 36 with evenly distributed intervals are placed to prevent the entire surface of the top cover 3 from contacting the box body in case of abnormal conditions, thus causing large-area damage. The front half of the top cover 3 cooperates with the front panel 2, and the rear half of the top cover 3 cooperates with the rear case 1, where the rear half is higher than the front half.
