Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to an air conditioner. Background Technology

[0002] Portable air conditioners typically integrate the evaporator, compressor, condenser, and fan into a single housing, facilitating their transport to different locations. However, to improve heat exchange efficiency, the heat generated by the condenser needs to be exhausted outdoors through an exhaust duct. Since the duct assembly connecting to the exhaust duct is usually located at the rear of the air conditioner, and the evaporator is situated between the exhaust fan and the duct assembly, the thickness of the portable air conditioner increases in the front-to-back direction, hindering miniaturization design.

[0037] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein 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 with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0038] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0039] In the description of this utility model, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0040] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0041] To address the technical problem of excessive thickness in the front-to-back direction of air conditioners, this utility model provides an air conditioner that optimizes the positional layout of the impeller, first heat exchanger, and duct assembly, facilitating miniaturization in the front-to-back direction. The air conditioner according to this utility model embodiment is described below with reference to the accompanying drawings.

[0042] Reference Figure 1 , Figure 2 and Figure 3 As shown, in an embodiment of this utility model, the air conditioner 1000 includes an air outlet assembly 100, an air duct assembly 200, and a first heat exchanger 130. The air outlet assembly 100 includes an air duct housing 110, a guide housing 112, and a fan 120. The guide housing 112 is connected to the side of the air duct housing 110 opposite to the air outlet direction of the air outlet assembly 100, for example, the guide housing 112 is connected to the rear side of the air duct housing 110. The air duct assembly 200 is installed on the side of the air duct housing 110 opposite to the air outlet direction and is arranged side by side with the guide housing 112 in the left-right direction, for example, the air duct assembly 200 is located on the rear side of the air duct housing 110. (Refer to...) Figure 6 As shown, the air duct shell 110 and the guide shell 112 together define the air outlet duct 113 of the air outlet assembly 100. The air duct shell 110 is provided with an air outlet 117, and the guide shell 112 is provided with an air inlet 111 on the side away from the air duct assembly 200. The first heat exchanger 130 is provided in the air outlet duct 113, and the impeller 120 is provided in the air outlet duct 113 and is used to drive air to enter from the air inlet 111, flow through the first heat exchanger 130, and then flow out from the air outlet 117.

[0043] The air outlet 117 is equipped with an air guide grille 118, which is used to adjust the air outlet direction of the air outlet 117. The impeller 120 is connected to a motor drive, and the impeller 120 can drive air from the air inlet 111 into the air outlet duct 113 under the drive of the motor.

[0044] It should be noted that the air outlet assembly 100 refers to the channel system that guides airflow. The air outlet assembly 100 can be implemented by combining an injection-molded plastic housing with a centrifugal impeller 120 or a cross-flow impeller 120. For example... Figure 4As shown, the wind turbine 120 is a cross-flow wind turbine 120, and the rotation axis of the cross-flow wind turbine 120 extends in the left-right direction. Or refer to Figure 5 As shown, the impeller 120 is a centrifugal impeller 120, and the rotation axis of the centrifugal impeller 120 extends in the front-to-back direction. The appropriate impeller 120 type should be selected based on the actual situation.

[0045] The duct shell 110 refers to the main structure constituting the duct, and its air inlet 111 can be located on the side or top. It can be formed by splicing split injection molded parts to constrain the airflow direction. The duct assembly 200 refers to the air duct used to connect indoor and outdoor spaces. It can adopt a double-layer tube structure, with an annular channel formed between the outer and inner tubes to achieve directional delivery of heat exchange gases. The first heat exchanger 130 refers to the component used for heat exchange between air and refrigerant. It can be a finned tube structure and is arranged laterally along the air outlet duct 113 to improve heat exchange efficiency by increasing the heat exchange area. The first heat exchanger 130 can be located on at least one side of the duct assembly 200, such as both the left and right sides of the duct assembly 200. It should be noted that when the air conditioner 1000 is cooling, the first heat exchanger 130 is used as an evaporator; when the air conditioner 1000 is heating, the first heat exchanger 130 is used as a condenser.

[0046] Understandably, with the above-described solution, an air inlet 111 is provided in the duct housing 110 of the air outlet assembly 100, and the first heat exchanger 130 is located in the air outlet duct 113 of the air outlet assembly 100. When the impeller 120 is working, it drives air to flow from the air inlet 111 into the air outlet duct 113, so that the air exchanges heat with the first heat exchanger 130 when it passes through it. Depending on the operating mode of the air conditioner 1000, the air conditioner 1000 can blow out cold or warm air from the air outlet 117. The duct assembly 200 is installed on the rear side of the air outlet assembly 100, while the first heat exchanger 130 is installed on at least one side of the duct housing 110 along the left-right direction of the duct assembly 200. Compared to the solution where the first heat exchanger 130 is located on the front side of the duct assembly 200, the solution of this embodiment can effectively reduce the space occupied by the air conditioner 1000 in the front-back direction. Since the first heat exchanger 130 is arranged to extend in the front-to-back direction, the thickness of the air conditioner 1000 in the left-to-right direction will not be significantly increased, which is conducive to the miniaturization design of the air conditioner 1000.

[0047] Reference Figure 1As shown in the embodiment of this utility model, the air inlet 111 is located on the side of the guide shell 112 away from the duct assembly 200, and the first heat exchanger 130 is installed at the air inlet 111. The side of the guide shell 112 away from the air inlet 111 along the first direction is spaced apart from or abuts against the outer wall of the duct assembly 200. The guide shell 112 refers to the structure in the duct shell 110 used to guide airflow into the air inlet 111, and can also be used to accommodate the first heat exchanger 130. The air inlet 111 being located on the side of the guide shell 112 away from the duct assembly 200 means that the opening direction of the air inlet 111 is opposite to the arrangement direction of the duct assembly 200, which can improve air intake efficiency and avoid interference between the airflow and the duct assembly 200. The first heat exchanger 130 is installed at the air inlet 111, meaning that the heat exchanger is arranged close to the air inlet 111. This ensures that the air entering from the air inlet 111 exchanges heat with the first heat exchanger 130, thereby improving heat exchange efficiency. The side of the guide shell 112 facing away from the air inlet 111 in the left-right direction is spaced apart from or abuts against the outer wall of the duct assembly 200. This means that there is a gap or contact between the two in the left-right direction, so that the relative relationship between the guide shell 112 and the duct assembly 200 can be flexibly configured according to space requirements.

[0048] By adopting the above scheme, the air inlet 111 of the guide shell 112 is arranged on the side away from the duct assembly 200, allowing air to enter the air duct from the area away from the duct assembly 200, thus avoiding obstruction of the airflow by the duct assembly 200. The first heat exchanger 130 is directly installed at the air inlet 111, and the air immediately exchanges heat with the heat exchanger after entering, reducing energy loss in the flow path and improving heat exchange efficiency. After the guide shell 112 extends outward in the left and right directions, it can be either spaced apart from or directly abut against the outer wall of the duct assembly 200, thereby avoiding overlap between the guide shell 112 and the duct assembly 200 in the front and back directions, effectively reducing the overall thickness of the air conditioner 1000, and realizing a miniaturized design of the whole unit.

[0049] Reference Figure 6 As shown, Figure 6The dashed arrows in the diagram indicate the direction of airflow. In this embodiment of the invention, the minimum distance between the side of the guide shell 112 away from the air inlet 111 and the first heat exchanger 130 in the left-right direction is L, where L is greater than or equal to 8 mm. For example, L can be 8 mm, 9 mm, 10 mm, 15 mm, 20 mm, 30 mm, etc. The minimum distance refers to the interval between the two closest points in the left-right direction between the side wall of the inner wall of the guide shell 112 away from the air inlet 111 and the first heat exchanger 130. By maintaining a minimum distance between the guide shell 112 and the first heat exchanger 130, the obstruction encountered by the air entering at the air inlet 111 when flowing towards the impeller 120 is reduced. When the space between the guide shell 112 and the first heat exchanger 130 increases, the airflow can be more evenly distributed when entering the duct shell 110, reducing local eddies or resistance, thereby improving the efficiency of the impeller 120 in driving the air. It effectively solves the problems of high air intake resistance and low heat exchange efficiency caused by the small distance between the air guide shell 112 and the heat exchanger in the portable air conditioner 1000. While ensuring the miniaturization of the whole unit, it optimizes the internal airflow distribution and improves the overall performance.

[0050] Reference Figure 1 As shown in the embodiment of this utility model, the duct shell 110 includes two guide shells 112. The first heat exchanger 130 includes a first heat exchange section 131 and a second heat exchange section 132. The first heat exchange section 131 and the second heat exchange section 132 are respectively located on both sides of the duct assembly 200 in the left-right direction and are respectively installed at the air inlets 111 of the two guide shells 112. The two guide shells 112 are spaced apart in the left-right direction and are connected by a connecting section 116. The connecting section 116 is arranged around the outside of the duct assembly 200. The enclosed space of the connecting section 116 and the two guide shells 112 communicates with the air inlet end of the duct shell 110, and the connecting section 116 is adapted to a portion of the outer wall of the duct assembly 200.

[0051] The first heat exchange section 131 and the second heat exchange section 132 refer to independent heat exchange modules located on both sides of the duct assembly 200. They can be implemented using a parallel finned tube structure, and the airflow distribution is uniform through a symmetrical layout. The connecting section 116 refers to the structure that connects the two guide shells 112.

[0052] Using the above scheme, two guide shells 112 are respectively installed on the left and right sides of the duct assembly 200. A heat exchange section is installed at the air inlet 111 of each guide shell 112, allowing air to enter the heat exchange area simultaneously from both sides. This dual-sided layout optimizes space utilization, making the overall structure of the air conditioner 1000 more compact. The connecting part 116 extends from the two guide shells 112 towards the rear of the duct assembly 200, forming a semi-enclosed structure. Its enclosed space communicates with the air inlet channel of the duct shell 110. After flowing through the heat exchange sections on both sides, the air flows into the duct shell 110 through the continuous flow channel formed by the connecting part 116, where it is driven by the impeller 120 to form a stable airflow.

[0053] Reference Figure 3 and Figure 6 As shown in the embodiment of this utility model, the sidewall of the connecting portion 116 facing the duct assembly 200 is constructed as a first arc surface 1161, which surrounds a portion of the outer wall of the duct assembly 200. At least a portion of the sidewall of the guide shell 112 facing the duct assembly 200 is constructed as a second arc surface 1121, which surrounds a portion of the outer wall of the duct assembly 200. It should be noted that the first arc surface 1161 is concave in the direction away from the duct assembly 200, and the first arc surface 1161 is adapted to the curved surface of the outer wall of the duct assembly 200, effectively avoiding the duct assembly 200. Simultaneously, the second arc surface 1121 is also concave in the direction away from the duct assembly 200 and is adapted to the curved surface of the outer wall of the duct assembly 200, making the overall structure of the air conditioner 1000 more compact.

[0054] Reference Figure 7 and Figure 8 As shown in the embodiment of this utility model, the air conditioner 1000 further includes a partition 300, and the air outlet assembly 100 and the first heat exchanger 130 are installed on the partition 300. The partition 300 includes a first water receiving area 310, which is located below the first heat exchanger 130 and is used to collect the condensate of the first heat exchanger 130. The partition 300 is also provided with at least one drain hole 321 for communicating with the first water receiving area 310.

[0055] It should be noted that the partition plate 300 refers to the supporting structure that carries the air outlet assembly 100 and the first heat exchanger 130. It can be made by stamping metal sheet or by injection molding a plastic part. The first water receiving area 310 refers to the water collection tank located below the heat exchanger. It can be made by injection molding a groove structure with baffles to collect condensate generated on the surface of the heat exchanger. The drain hole 321 refers to the drainage channel located at the bottom of the second water receiving area 320. Multiple circular drain holes 321 can be arranged, for example, five holes evenly distributed.

[0056] Understandably, the first water receiving area 310 directly receives the condensate dripping from the first heat exchanger 130, and the condensate is then discharged through the drain hole 321, which can effectively prevent condensate from overflowing and ensure drainage efficiency.

[0057] Reference Figure 3 As shown in the embodiment of this utility model, the air conditioner 1000 further includes a compressor 410, an electrical control box 420, and an exhaust fan 480 located below the partition 300. The compressor 410 and the electrical control box 420 are located on one side of the second heat exchanger 430 along the left-right direction, and the exhaust fan 480 is located on the other side of the second heat exchanger 430 along the left-right direction. The second heat exchanger 430 is provided between the exhaust fan 480 and the compressor 410. The second heat exchanger 430 is installed on the side of the partition 300 away from the first heat exchanger 130, that is, the second heat exchanger 430 is located on the lower side of the partition 300. The second heat exchanger 430 can be implemented as a finned heat exchanger or a microchannel heat exchanger, and its installation position is limited to the area of ​​the partition 300 away from the first heat exchanger 130 to form an independent heat exchange space. When the first heat exchanger 130 is an evaporator, the second heat exchanger 430 is a condenser. When the first heat exchanger 130 is a condenser, the second heat exchanger 430 is an evaporator. With this arrangement, the compressor 410 and the electrical control box 420 are centrally located on the same side of the second heat exchanger 430, while the exhaust fan 480 is independently located on the other side. This layout effectively utilizes the lateral space and avoids increasing the thickness of the air conditioner 1000 in the front-to-back direction.

[0058] Reference Figure 7 and Figure 8 As shown in the embodiment of this utility model, the partition 300 further includes a second water receiving area 320. The height of the second water receiving area 320 is lower than the height of the first water receiving area 310. The second water receiving area 320 and the first water receiving area 310 are connected. The bottom wall of the second water receiving area 320 has at least one drainage hole 321. The second water receiving area 320 refers to a secondary water collection tank connected to the first water receiving area 310. It can be implemented using a stepped descending guide channel structure, achieving gravity drainage through the height difference. The interconnected design allows accumulated water to naturally flow into the lower second water receiving area 320, and then be discharged uniformly through the drainage hole 321. The condensate collection system is integrated with the load-bearing structure, ensuring drainage efficiency while reducing the number of components.

[0059] Reference Figure 7As shown in the embodiment of this utility model, multiple drain holes 321 are provided and arranged at intervals along the extension direction of the second heat exchanger 430. Along the axial direction of the drain holes 321, the projection of the drain holes 321 at least partially coincides with the projection of the second heat exchanger 430. The drain holes 321 are through holes for discharging condensate and can be implemented using a circular or elliptical hole structure. Their axial projection at least partially coincides with the second heat exchanger 430, thus associating the condensate discharge path with the position of the second heat exchanger 430. The second heat exchanger 430 can extend in the front-back direction; therefore, the multiple drain holes 321 are also arranged at intervals in the front-back direction, and can be arranged in a uniform or non-uniform interval manner to achieve dispersed discharge of condensate.

[0060] Because the location of the drain hole 321 partially overlaps with the area of ​​the second heat exchanger 430 through axial projection, the discharged condensate can directly act on the area where the second heat exchanger 430 is located. For example, by guiding the condensate from the top to the bottom of the second heat exchanger 430, the second heat exchanger 430 can be effectively cooled, thereby improving its heat exchange efficiency. Multiple drain holes 321 are spaced apart along the length of the second heat exchanger 430 to avoid concentrated condensate discharge leading to localized water accumulation. At the same time, the dispersed drainage paths improve overall drainage efficiency, enhance the overall structural compactness, and improve drainage reliability.

[0061] Reference Figure 8 As shown in the embodiment of this utility model, the bottom wall of the first water receiving area 310 has at least one rib 311. The rib 311 extends along a second direction and is used to guide the condensate from the first water receiving area 310 to the second water receiving area 320. The second direction is perpendicular to the first direction, and the first heat exchanger 130 is supported by the rib 311. The second direction can be a front-back direction, and the extension direction of the rib 311 is the same as the extension direction of the first heat exchanger 130. The rib 311 refers to the protruding structure provided on the bottom wall of the first water receiving area 310, which can be integrally formed by injection molding and can provide support points for the first heat exchanger 130. Since the first heat exchanger 130 includes a first heat exchange part 131 and a second heat exchange part 132, and both the first heat exchange part 131 and the second heat exchange part 132 extend along the front-back direction, at least two ribs are provided at the bottom of each heat exchange part to provide stable support for the first heat exchange part 131 and the second heat exchange part 132, which can improve the stability and reliability of the support for the heat exchange part. At the same time, the ribs 311 can also prevent the first heat exchange section 131 and the second heat exchange section 132 from directly contacting the bottom wall of the first water receiving area 310. Therefore, the first heat exchange section 131 and the second heat exchange section 132 will not obstruct the flow of condensate, reducing the accumulation of condensate in the first water receiving area 310, which could lead to the breeding of mosquitoes, foul odors, and other problems.

[0062] Reference Figure 2As shown in the embodiment of this utility model, the air conditioner 1000 further includes a chassis 440, on which a second heat exchanger 430 and an exhaust fan 480 are mounted. The exhaust fan 480 drives airflow through the second heat exchanger 430. Casters 460 can be installed at the bottom of the chassis 440 to facilitate the movement of the air conditioner 1000. The duct assembly 200 includes an outer duct body 210 and an inner duct body 220, with the inner duct body 220 disposed inside the outer duct body 210. The outer duct body 210 guides air to the second heat exchanger 430, and the inner duct body 220 exhausts air from the exhaust fan 480 outdoors. The chassis 440 refers to the support structure for supporting the internal components of the air conditioner 1000, and can be made of sheet metal or injection-molded structure, providing an installation base for the heat exchanger, duct, and duct assembly 200. The outer tube 210 refers to a tubular structure with a hollow channel, which can be made of plastic or metal. The space formed inside it is used to guide airflow into the second heat exchanger 430 for heat exchange. The inner tube 220 refers to an independent pipe nested inside the outer tube 210, which can be made of metal or plastic. The nested arrangement with the outer tube 210 achieves air diversion, thereby directly exhausting the airflow from the exhaust fan 480 to the outside. Alternatively, the duct assembly 200 may also include an exhaust duct, with the exhaust duct and outer tube 210 arranged side by side, for exhausting the air from the exhaust fan 480 to the outside.

[0063] Understandably, the chassis 440 serves as the overall support structure, upon which the second heat exchanger 430 and the exhaust fan 480 are fixed. Driven by the exhaust fan 480, airflow enters from the outer pipe 210 and delivers air to the second heat exchanger 430. After heat exchange between the air and the second heat exchanger 430, the air is discharged from the inner pipe 220, which improves the overall heat exchange efficiency and ease of installation of the air conditioner 1000.

[0064] Reference Figure 1 and Figure 6 As shown in the embodiment of this utility model, the axis of the inner tube 220 is offset from the axis of the outer tube 210. Axis offset means that the center lines of the inner tube 220 and the outer tube 210 are spatially misaligned, i.e., the axes of the inner tube 220 and the outer tube 210 do not coincide. This can be achieved by adjusting the installation positions of the inner tube 220 and the outer tube 210 or by adopting an eccentric structure design, thus forming an asymmetrical flow channel between the inner and outer tubes 210, reducing mutual airflow interference, making the air intake process of the outer tube 210 smoother, effectively reducing wind loss, and improving air intake efficiency. The cross-section of the outer tube 210 is circular, and the cross-section of the inner tube 220 is also circular; both the outer tube 210 and the inner tube 220 are flexible hoses. Circular flexible hoses have good flexibility, and the joints connecting the flexible hose to the sealing plate can rotate relative to each other, providing high flexibility and adapting to the installation needs of different windows.

[0065] Reference Figure 1 and Figure 2 As shown in the embodiment of this utility model, the air conditioner 1000 further includes a housing 400, and an air duct housing is installed inside the housing 400. The housing 400 includes a front panel 470 and a rear panel 450. The rear panel 450 protrudes in a direction away from the front panel 470 to form an outward protrusion. The air guide housing 112 and the air duct assembly 200 are disposed above the outward protrusion. The ends of the air guide housing 112 and the outward protrusion opposite to the front panel 470 are flush. The flush arrangement means that the upper ends of the air guide housing 112 and the outward protrusion 451 are aligned. The design that the ends of the air guide housing 112 and the outward protrusion 451 opposite to the front panel 470 are flush effectively reduces the overall thickness of the air conditioner 1000 in the front-rear direction, while keeping the volume occupied by the air conditioner 1000 unchanged. It achieves a miniaturized design while maintaining the original cabinet capacity, making the structure of the air conditioner 1000 more compact.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
