Description

Technical Field

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

[0002] This section provides only background information relevant to this disclosure and is not necessarily prior art.

[0003] Currently, most of the square cabinet-style air conditioner indoor units on the market adopt a side-intake air duct structure design. The air intake area is usually located on the side of the lower panel, and the opening size is relatively small, which limits the air intake volume. At the same time, the evaporator is usually located at the end of the air outlet area, and the overall structure design is planar, which limits the contact area with the incoming airflow, resulting in a small effective heat exchange area. Utility Model Content

[0004] The purpose of this invention is to at least solve the problem of low heat exchange efficiency in existing air conditioners due to their small air inlet area, heat exchanger being far from the air inlet area, and planar design. This objective is achieved through the following technical solution: This utility model proposes an air conditioner, comprising: The housing has an air inlet area and an air outlet area, and the air inlet area is multiple and spaced apart along the circumference of the housing; A duct assembly defining an air supply duct that connects the air inlet area and the air outlet area; A heat exchange assembly includes a heat exchanger disposed within the housing. The heat exchanger includes a plurality of heat exchange sections arranged circumferentially along the housing. Each air inlet zone is respectively provided with a heat exchange section. Along the arrangement direction of the plurality of heat exchange sections, the heat exchange sections located at the beginning and end are spaced apart to form an opening end of the heat exchanger. The opening end is disposed opposite to and communicates with the air duct assembly.

[0005] This utility model of an air conditioner achieves air intake from multiple directions by setting multiple air intake zones distributed on different side walls of the casing, increasing the overall air intake area and effectively improving the air volume. Simultaneously, the heat exchanger is positioned close to the air intake zones and includes multiple heat exchange sections, with each air intake zone corresponding to a heat exchange section. This ensures that each air intake zone efficiently guides airflow into its corresponding heat exchange section, shortening the contact path between the airflow and the heat exchanger and accelerating the heat exchange start-up speed. Furthermore, the multiple heat exchange sections are arranged circumferentially along the casing, with open ends that connect to the air duct assembly. This gives the heat exchanger a non-planar, multi-faceted, three-dimensional structure, fully utilizing the internal space and increasing the effective contact area with the airflow, thereby improving overall heat exchange efficiency and achieving faster and more efficient cooling or heating effects.

[0016] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0017] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0018] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0019] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations.

[0020] like Figures 1 to 22 As shown, according to an embodiment of the present invention, an air conditioner 100 is proposed, including a housing 1, an air duct assembly 2, and a heat exchange assembly 3.

[0021] The housing 1 is provided with an air inlet area and an air outlet area 13. There are multiple air inlet areas, which are spaced apart along the circumference of the housing 1. The housing 1 can be rectangular, cylindrical, etc. In this embodiment, the housing 1 is rectangular and includes multiple side walls connected end to end. The multiple air inlet areas can be distributed on different side walls of the housing 1, such as the left side, right side, front, etc. The multiple air inlet areas can increase the overall air inlet area, allowing more outdoor air or indoor return air to enter the interior of the housing 1, providing sufficient airflow for subsequent heat exchange.

[0022] The air duct assembly 2 defines the air supply duct, which connects the air inlet area and the air outlet area 13. The air supply duct is an airflow channel connecting the air inlet area and the air outlet area 13, used to transport the air drawn in from the air inlet area to the air outlet area 13 for discharge. The airflow enters the air inlet area in an orderly manner, undergoes heat exchange in the heat exchanger 30, and then enters the air duct assembly 2, finally being blown out from the air outlet area 13. This improves airflow transmission efficiency, avoids airflow turbulence, and ensures the uniformity and stability of the air supply.

[0023] The heat exchange assembly 3 includes a heat exchanger 30, which is disposed inside the housing 1 and located near the air inlet area. This shortens the contact path between the airflow and the heat exchanger 30. The heat exchanger 30 includes multiple heat exchange sections arranged circumferentially along the housing 1. These multiple heat exchange sections can form a larger effective heat exchange surface. Each air inlet area is respectively provided with a heat exchange section, enabling each air inlet area to efficiently guide the airflow into the corresponding heat exchange section and ensuring that the air entering the housing 1 can fully contact the heat exchanger 30, thereby improving heat exchange efficiency. Along the arrangement direction of the multiple heat exchange sections, the heat exchange sections located at the beginning and end are spaced apart to form the open end of the heat exchanger 30. The open end is positioned opposite to and connected to the air duct assembly 2, allowing the heat-exchanged air to smoothly enter the air duct assembly 2, ensuring continuous air supply and improving the air supply effect.

[0024] The air conditioner 100 of this utility model achieves air intake from multiple directions by setting multiple air intake zones distributed on different side walls of the housing 1, increasing the overall air intake area and effectively improving the air intake volume. At the same time, the heat exchanger 30 is set close to the air intake zone and includes multiple air intake zones. Each air intake zone is respectively provided with a heat exchange part, so that each air intake zone can efficiently guide the airflow into the corresponding heat exchange part, shortening the contact path between the airflow and the heat exchanger 30 and accelerating the heat exchange start-up speed. In addition, the multiple heat exchange parts are arranged sequentially along the side wall direction, and their first and last ends form open ends that are relatively connected to the air duct assembly 2, so that the heat exchanger 30 has a non-planar, multi-faceted three-dimensional structure, making full use of the internal space, increasing the effective contact area with the airflow, thereby improving the overall heat exchange efficiency and achieving a faster and more efficient cooling or heating effect.

[0025] In some embodiments of this utility model, the multiple heat exchange sections include a first heat exchange section 301, a second heat exchange section 302, and a third heat exchange section 303 connected in sequence. The housing 1 includes a rear housing assembly 10 and a panel assembly 11 disposed on the front side of the rear housing assembly 10. The panel assembly 11 includes three side wall sections arranged circumferentially thereon. A first air inlet area 111, a second air inlet area, and a third air inlet area 112 are respectively disposed on the three side walls. The first air inlet area 111, the second air inlet area, and the third air inlet area 112 are respectively disposed in correspondence with the first heat exchange section 301, the second heat exchange section 302, and the third heat exchange section 303.

[0026] like Figures 3 to 6 As shown, the first air inlet area 111, the second air inlet area, and the third air inlet area 112 are respectively located on different sides of the panel assembly 11. For example, the first air inlet area 111 can be located on the left side wall of the panel assembly 11, the second air inlet area can be located on the right side wall of the panel assembly 11, and the third air inlet area 112 can be located on the front side wall of the panel assembly 11. The first air inlet area 111 and the second air inlet area are fan-shaped. The fan-shaped air inlet area is usually formed by a flanging process, such as bending the edge of the side plate 102 outward or inward to form a flanging, which enhances the rigidity of the side wall. The arc edge of the fan shape can effectively disperse the external impact force and internal airflow pressure on the side plate 102, and improve the overall strength. The third air inlet area 112 is rectangular. The rectangular air inlet area can simplify the production process, reduce the processing difficulty, improve production efficiency, and is suitable for mass production. The shapes of the first air intake zone 111, the second air intake zone, and the third air intake zone 112 can also be circular, trapezoidal, triangular, or irregular, etc., and their size and distribution density can be optimized according to the overall design of the air conditioner and the air intake volume requirements. Filters can also be installed at the air intake zones to filter dust, pollen, and other impurities in the air, ensuring that the air entering the housing 1 is clean. This also helps protect the heat exchanger 30 and the air duct assembly 2, extending their service life.

[0027] The heat exchanger 30 comprises a first heat exchanger 301, a second heat exchanger 302, and a third heat exchanger 303 connected in sequence. The heat exchanger 30 has a U-shaped cross-section. The number of the three heat exchangers corresponds to the number of the three air inlet zones, with each zone corresponding to the first air inlet zone 111 (corresponding to the first heat exchanger 301), the second air inlet zone (corresponding to the second heat exchanger 302), and the third air inlet zone 112 (corresponding to the third heat exchanger 303). The U-shaped heat exchanger 30 increases the heat exchange area by 20%, improving heat exchange efficiency. Furthermore, the air drawn into each air inlet zone can directly enter the corresponding heat exchanger for heat exchange, enhancing the targeting and efficiency of heat exchange. The heat exchangers at both ends form the open ends of the heat exchanger 30. For example, an opening is formed between the first end of the first heat exchange section 301 and the tail end of the third heat exchange section 303. This opening is positioned opposite to and connected to the air duct assembly 2, so that the air after heat exchange in the heat exchange section can smoothly enter the air duct assembly 2. The arrow in the figure indicates the air flow direction. Guided by the air duct assembly 2, the processed air is evenly delivered to the air outlet area 13, achieving a high-efficiency and stable air supply effect.

[0028] In other embodiments, the cross-sectional shape of the heat exchanger 30 may also be L-shaped, G-shaped, or similar. Figure 7 As shown, the two arms of the L-type heat exchanger 30 correspond to the air inlet areas of different side walls, such as the left air inlet area and the rear air inlet area, allowing airflow to enter the heat exchanger 30 from two vertical directions, forming multi-directional airflow coverage. The G-type heat exchanger 30 includes a first heat exchange section 301, a second heat exchange section 302, a third heat exchange section 303, and a fourth heat exchange section arranged sequentially, wherein the heat exchange sections at the beginning and end are spaced apart, that is, the first heat exchange section 301 and the fourth heat exchange section are spaced apart; as shown... Figure 8 As shown, a planar extension section 304 can be added at the turning connection of the U-shaped heat exchanger 30, i.e., the corner or direction change part of the U-shape, to ensure efficient heat exchange while taking into account spatial adaptability.

[0029] In some embodiments of this utility model, the air duct assembly 2 includes an air duct volute 20 and a centrifugal impeller 21 disposed on the air duct volute 20. The air duct volute 20 is provided with a volute inlet area 203 and a volute outlet area 204 that are connected to the air supply duct. The open end is disposed opposite to the volute inlet area 203, and the volute outlet area 204 is disposed opposite to the outlet area 13.

[0030] like Figure 13As shown, the duct volute 20 includes an upper volute 201 and a lower volute 202 connected to each other. The duct volute 20 is fixed to the inner side of the rear shell assembly 10 of the housing 1 by means of clips, screws, or welding. The centrifugal impeller 21 is disposed on the lower volute 202. The volute inlet area 203 and the volute outlet area 204 are respectively disposed on the lower volute 202 and the upper volute 201. The volute inlet area 203 is opened on the side of the lower volute 202 near the heat exchanger 30, and is disposed opposite to the opening end of the heat exchanger 30. There is a gap of about 5 mm between the centrifugal impeller 21 and the lower volute 202, so that the outer edge of the blade maintains a safe distance from the inner wall of the lower volute 202, reducing the possibility of motion interference. After heat exchange, the air flows out of the heat exchange section and can directly enter the volute inlet area 203 without undergoing additional turns or diffusion, avoiding pressure loss and eddy phenomena caused by sudden changes in airflow path, and improving airflow delivery efficiency. The ejected airflow directly enters the spiral flow channel inside the volute, and is then guided along the volute flow channel to the volute outlet area 204, and finally blown into the room through the outlet area 13. The lower volute 202 and the heat exchanger 30 form a tight contact in the front-to-back direction to achieve a sealed connection, so that all air entering the air duct must pass through the heat exchanger 30 for heat exchange treatment, improving heat exchange efficiency. At the same time, depending on the different operating states of the fan, a stable negative or positive pressure environment is formed inside the air duct, avoiding air pressure fluctuations caused by gap leakage, and improving the uniformity and comfort of the air outlet.

[0031] In some embodiments of the present invention, the heat exchange assembly 3 further includes connecting members 31 disposed on both sides of the heat exchanger 30, and the rear shell assembly 10 includes a back plate 101 and two side plates 102 connected to both sides of the back plate 101. The side of the two connecting members 31 away from the heat exchanger 30 is respectively connected to one of the two side plates 102.

[0032] like Figure 9As shown, there are two connectors 31, located on the left and right sides of the heat exchanger 30. For example, the left connector 31 is connected to the left edge of the heat exchanger 30, and the right connector 31 is connected to the right edge of the heat exchanger 30. They are rigidly connected to the heat exchanger 30 by means of screws, clips, or welding. The back plate 101 is located on the outermost rear surface of the shell 1. Two side plates 102 are connected to the left and right sides of the back plate 101, forming a U-shaped structure together with the back plate 101. The side of the connector 31 away from the heat exchanger 30 is directly connected to one of the two side plates 102 of the rear shell assembly 10 by mechanical fixing methods, such as screw holes, clip insertion, or bolt locking. That is, the connector 31 on the left side of the heat exchanger 30 is fixed to the inner wall of the left side plate 102 by screws, and the connector 31 on the right side of the heat exchanger 30 is fixed to the inner wall of the right side plate 102 by screws. The fixing of the two side connectors 31 to the side plate 102 provides support and limit for the heat exchanger 30, restricting the left and right offset and front and back sway of the heat exchanger 30, ensuring the stability and reliability of the heat exchanger 30 in long-term operation, reducing noise or performance degradation caused by structural loosening, and extending the service life of the product.

[0033] In some embodiments of this utility model, the connector 31 includes a first connecting plate 311 and a second connecting plate 312. The first connecting plate 311 is connected to the second connecting plate 312 and the side plate 102 respectively. The second connecting plate 312 is connected to the heat exchanger 30. The first connecting plate 311 is provided with a first positioning part, and the side plate 102 is provided with a first mating part. The first positioning part and the first mating part are mated.

[0034] like Figure 12 As shown, the second connecting plate 312 is an L-shaped plate, and it is connected to both the heat exchanger 30 and the first connecting plate 311. The first connecting plate 311 is a strip-shaped flat plate. A first positioning part is provided on the side of the first connecting plate 311 near the side plate 102, and a first mating part is provided on the end face of the side plate 102 away from the back plate 101. The first positioning part and the first mating part are connected to each other, so as to realize the precise and rapid pre-positioning of the connecting piece 31 and the side plate 102, improve the assembly efficiency, and enhance the stability and vibration resistance of the overall structure.

[0035] In some embodiments of this utility model, the first positioning part includes one of the first positioning buckle 313 and the first positioning groove 314, and the first mating part includes the other of the first positioning buckle 313 and the first positioning groove 314.

[0036] In this embodiment, as Figures 9 to 12As shown, the first connecting plate 311 is provided with multiple first positioning buckles 313, which are spaced apart along the length of the first connecting plate 311. Each first positioning buckle 313 is an outwardly protruding elastic structure on the first connecting plate 311, integrally injection molded with the first connecting plate 311 or stamped into a single structural component. The side plate 102 is provided with multiple first positioning grooves 314, which are spaced apart along the length of the side plate 102 and correspond one-to-one with the first positioning buckles 313. The shape of the first positioning grooves 314 is adapted to the shape of the first positioning buckles 313. During assembly, the first positioning buckles 313 are embedded in the first positioning grooves 314 of the side plate 102, achieving precise alignment of the connector 31, limiting the displacement of the connector 31 in the left-right / front-back directions, providing initial vertical support for the connector 31, facilitating assembly, and improving assembly efficiency.

[0037] In other embodiments, a first positioning groove 314 may be provided on the first connecting plate 311, and a first positioning buckle 313 may be provided on the side plate 102. The quantity of both can be adjusted according to actual assembly requirements, the specifications of the heat exchanger 30, and the characteristics of the air conditioner 100 model. In addition, the first positioning part and the first mating part may also be structures such as positioning posts and positioning holes.

[0038] In some embodiments of this utility model, a first connecting plate 311 is provided with a first connecting hole 315, and a second connecting plate 312 is provided with a second connecting hole corresponding to the first connecting hole 315. The first connecting hole 315 and the second connecting hole are connected by fasteners. And / or, the first connecting plate 311 is provided with a third connecting hole 316, and the side plate 102 is provided with a fourth connecting hole 317 corresponding to the third connecting hole 316. The third connecting hole 316 and the fourth connecting hole 317 are connected by fasteners.

[0039] "And / or" indicates that the two connection structures are optional combinations, including fixing only the first connection hole 315 and the second connection hole with fasteners; or fixing only the third connection hole 316 and the fourth connection hole 317 with fasteners; or, using both of the above schemes at the same time, that is, the first connection plate 311 and the second connection plate 312 are connected through the first connection hole 315 and the second connection hole, and the first connection plate 311 and the side plate 102 are connected through the third connection hole 316 and the fourth connection hole 317.

[0040] In this embodiment, as Figures 10 to 12 , Figure 14 , Figure 15As shown, the first connecting plate 311 is provided with a plurality of first connecting holes 315, which extend along the length of the first connecting plate 311. The first connecting holes 315 can be flanged holes, through holes, or threaded holes. The second connecting plate 312 is provided with a plurality of second connecting holes, which extend along the length of the second connecting plate 312 and correspond one-to-one with the plurality of first connecting holes 315. The second connecting holes can be through holes or threaded holes, and the fasteners are screws, bolts, etc. During assembly, the first connecting holes 315 of the first connecting plate 311 are aligned with the second connecting holes of the second connecting plate 312. Then, the screws are inserted into the first connecting holes 315 from the side of the first connecting plate 311 away from the heat exchanger 30, screwed into the second connecting holes, and tightened. Alternatively, when the first connecting holes 315 and the second connecting holes are through holes, they are locked with nuts.

[0041] The first connecting plate 311 has multiple third connecting holes 316 near the edge of the side plate 102. These holes extend along the length of the first connecting plate 311 and can be flanged holes, through holes, or threaded holes. The side plate 102 has multiple fourth connecting holes 317, which also extend along the length of the side plate 102 and correspond one-to-one with the third connecting holes 316. These holes can be through holes or threaded holes. During assembly, the third connecting holes 316 of the first connecting plate 311 are aligned with the fourth connecting holes 317 of the side plate 102. Screws are then inserted into the fourth connecting holes 317 from the side of the third connecting plate away from the heat exchanger 30 and tightened. Alternatively, if the third connecting holes 316 and 317 are through holes, nuts are used to lock them in place.

[0042] In some embodiments of this utility model, the panel assembly 11 is provided with a second positioning part, and the side plate 102 is provided with a second mating part. The panel assembly 11 is pre-positioned on the side plate 102 through the cooperation of the second positioning part and the second mating part. The second positioning part and the second mating part simplify the assembly process and reduce the error rate, enabling the panel assembly 11 and the side plate 102 to achieve precise and rapid pre-positioning, effectively resisting fan vibration and external impact, preventing the panel assembly 11 from loosening, making abnormal noises, or deforming its appearance, and ensuring long-term operational reliability.

[0043] In some embodiments of this utility model, the second positioning part includes one of the second positioning buckle 318 and the second positioning groove 319, and the second mating part includes the other of the second positioning buckle 318 and the second positioning groove 319.

[0044] In this embodiment, as Figure 17 and Figure 18As shown, the panel assembly 11 is provided with multiple second positioning buckles 318, and multiple first positioning buckles 313 are spaced apart along the length direction of the panel assembly 11. The first positioning buckles 313 are elastic structures protruding outward from the first connecting plate 311, integrally injection molded with the first connecting plate 311 or stamped into an integral structural part. The side plate 102 is provided with multiple second positioning grooves 319, which are spaced apart along the length direction of the side plate 102 and correspond one-to-one with the second positioning buckles 318. The shape of the second positioning grooves 319 is adapted to the second positioning buckles 318. The first connecting plate 311 is also provided with multiple third positioning grooves, which are spaced apart along the length direction of the first connecting plate 311, and the second positioning grooves 319 and the third positioning grooves correspond one-to-one. During assembly, the second positioning buckle 318 on the panel assembly 11 is inserted into the second positioning groove 319 through the third positioning groove. After the second positioning buckle 318 has completely passed through the second positioning groove 319, the elastic second positioning buckle 318 returns to its natural state, and the head of the second positioning buckle 318 is engaged with the inner wall of the second positioning groove 319. At this time, the second positioning buckle 318 and the second positioning groove 319 form a tight engagement, restricting the relative displacement of the panel assembly 11 and the side plate 102 in the left-right / back-forward manner, thereby achieving precise pre-positioning of the panel assembly 11 and the side plate 102.

[0045] In other embodiments, a second positioning groove 319 may be provided on the panel assembly 11, and a second positioning buckle 318 may be provided on the side plate 102. The number of both can be adjusted according to actual assembly requirements, the specifications of the heat exchanger 30, and the characteristics of the air conditioner 100 model. In addition, the second positioning part and the second mating part may also be structures such as positioning posts and positioning holes.

[0046] In this embodiment, the panel assembly 11 and the side plate 102 are respectively provided with a plurality of one-to-one corresponding flange holes, through holes or threaded holes. After the panel assembly 11 and the side plate 102 are pre-positioned and connected, they are fastened by bolts. The bolt fastening uses pre-tightening force to make the panel assembly 11 and the side plate 102 fit tightly together, which restricts the relative displacement of the two in the horizontal (left and right / front and back) and vertical (up and down) directions, while enhancing the rigidity of the connection structure and ensuring the stability of long-term operation.

[0047] In this embodiment, as Figure 2As shown, the housing 1 also includes an air outlet frame 12, a top cover 14, and a chassis 15. The air outlet frame 12 is located on the front side of the rear housing assembly 10 and above the panel assembly 11, and is fixed by a detachable connection, such as a threaded connection or a snap-fit. The air outlet area 13 is located on the air outlet frame 12. The top cover 14 is located on the top of the rear housing assembly 10 and is detachably connected and fixed to the rear housing assembly 10 and the air outlet frame 12. The chassis 15 is located on the bottom of the rear housing assembly 10 and is detachably connected and fixed to the rear housing assembly 10 and the panel assembly 11.
