Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] The following description, with reference to the accompanying drawings, describes a heat pump air conditioner 100 according to an embodiment of the present invention.

[0027] like Figure 1and Figure 2 As shown, the heat pump air conditioner 100 includes a housing assembly 1, which includes a chassis 11, a column 12, and a panel 13.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, there are multiple columns 12, the lower ends of which are connected to the chassis 11 and spaced apart along the circumferential direction of the chassis 11. There are multiple panels 13, with one panel 13 between any two adjacent columns 12. The chassis 11, the multiple columns 12, and the multiple panels 13 define an open receiving cavity at the upper end, and a top cover assembly 2 is provided at the upper opening of the receiving cavity.

[0029] like Figure 2 As shown, a middle frame assembly 4 is provided in the receiving cavity, which divides the receiving cavity into an upper cavity and a lower cavity. A condenser assembly 5 is provided in the upper cavity. A water receiving tray 41 is provided on the upper surface of the middle frame assembly 4. The condenser assembly 5 is located above the water receiving tray 41, which is used to collect the condensate from the condenser assembly 5.

[0030] refer to Figure 3 As shown, the lower cavity is equipped with a piping system and other refrigeration components, as well as an electrical control box assembly 6. The piping system and other refrigeration components include a compressor assembly 7, an oil separator 81, a gas-liquid separator 82, a heat exchanger 3, and a piping system assembly. The compressor assembly 7 includes a first compressor 71 and a second compressor 72, which can be connected in series or in parallel. One end of the heat exchanger 3 is connected to the exhaust port of the compressor assembly 7, and the other end is connected to one end of the condenser assembly 5. The other end of the condenser assembly 5 is connected to the return port of the compressor assembly 7. An oil separator 81 can be installed between the heat exchanger 3 and the exhaust port of the compressor assembly 7, and a gas-liquid separator 82 can be installed between the condenser assembly 5 and the return port of the compressor assembly 7. A throttling device can also be installed between the heat exchanger 3 and the condenser assembly 5.

[0031] Optionally, the heat exchanger 3 is a plate heat exchanger. Of course, this utility model is not limited to this. The heat exchanger 3 can also be a shell-and-tube heat exchanger or a shell-and-tube heat exchanger, etc.

[0032] refer to Figure 3As shown, taking the length direction of chassis 11 as the left-right direction and the width direction of chassis 11 as the front-back direction as an example, the compressor assembly 7 and oil separator 81 are located on the front left side, and are arranged along the left-right direction. The compressor assembly 7 is located to the left of the oil separator 81, and the exhaust pipe of the compressor assembly 7 is located in front of the compressor assembly 7 and the oil separator 81. The gas-liquid separator 82 and heat exchanger 3 are located on the rear left side, and the gas-liquid separator 82 and the injection pipe are located behind the compressor assembly 7. The positions of the compressor assembly 7, oil separator 81, and gas-liquid separator 82 are basically the same. The electrical control box is located on the right side of the lower cavity.

[0033] In this invention, the outer contours of multiple panels 13 have the same shape and size. This allows multiple panels 13 to be formed using the same mold, enabling individual processing of only a small number of different structures, reducing the number of molds and lowering costs. Furthermore, the identical outer contours and sizes of the multiple panels 13 improve panel production efficiency, simplify assembly, and facilitate after-sales maintenance.

[0034] According to the embodiment of the present utility model, the heat pump air conditioner 100, by setting a panel 13 between any two adjacent columns 12, and the outer contours and sizes of multiple panels 13 being the same, can make multiple panels 13 processed by the same mold, requiring only individual processing for a small number of different structures, reducing the number of molds and lowering costs. Furthermore, the identical outer contours and sizes of multiple panels 13 can improve the production efficiency of the panels 13, and make the installation of the whole unit simpler and after-sales maintenance more convenient.

[0035] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the distance between any two adjacent columns 12 is the same along the circumferential direction of the chassis 11. This facilitates the connection between any two adjacent columns 12 using panels 13 of the same size. It also allows for setting the shape and size of the outer contour of multiple panels 13 to be the same, which can reduce the number of molds, lower costs, and improve the production efficiency of panels 13 by ensuring that the outer contour shape and size of multiple panels 13 are the same. Furthermore, it simplifies the installation of the entire machine and makes after-sales maintenance more convenient.

[0036] Of course, this utility model is not limited to this. When the distance between two adjacent columns 12 is different along the circumferential direction of the chassis 11 and the shape and size of the outer contour of multiple panels 13 are the same, multiple sets of structures for connecting with the columns 12 can be set on the panels 13. The connection structure at different positions can be selected to connect with the columns 12 according to the distance between two adjacent columns 12.

[0037] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the heat pump air conditioner 100 has a heat exchanger 3 and an inlet pipe 31 and an outlet pipe 32 connected to the heat exchanger 3. The inlet pipe 31 and the outlet pipe 32 are installed on the column 12. The multiple panels 13 have the same structure and size. The inlet pipe 31 and the outlet pipe 32 are positioned on the column 12 without passing through the panels 13, ensuring that the panels 13 do not need to be perforated due to the inlet pipe 31 and the outlet pipe 32. This better ensures that all panels 13 of the whole unit have the same size and shape, which can further improve the production efficiency of the panels 13, and make the whole unit installation simpler and after-sales maintenance more convenient.

[0038] In some other embodiments of this utility model, the inlet pipe 31 and the outlet pipe 32 are respectively passed through two panels 13. The two panels 13 through which the inlet pipe 31 and the outlet pipe 32 are passed have the same structure and size, and the remaining panels 13 have the same structure and size. This allows the two panels 13 through which the inlet pipe 31 and the outlet pipe 32 are passed to be of the same size, and the remaining panels 13 to be of the same size, so that the panels 13 have two sizes and shapes, minimizing the variety of panels 13, further improving the production efficiency of the panels 13, and making the overall machine installation simpler and after-sales maintenance more convenient.

[0039] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the multiple columns 12 include first columns 121 and second columns 122. A first column 121 is provided at each of the four corners of the chassis 11. Second columns 122 are provided on both sides of the chassis 11 in the width direction. The second columns 122 are located between two first columns 121 on the same side. The distance between two first columns 121 on the same side in the length direction of the chassis 11 is L1. The distance between adjacent first columns 121 and second columns 122 on the same side in the width direction of the chassis 11 is L2, and L1=L2.

[0040] Understandably, the first pillars 121 at the four corners of the chassis 11 are the left front first pillar, the left rear first pillar, the right front first pillar, and the right rear first pillar, respectively. The left front first pillar and the right front first pillar are located on the front side and on the left and right sides, respectively. The left rear first pillar and the right rear first pillar are located on the rear side and on the left and right sides, respectively. In addition, there is a front second pillar between the left front first pillar and the right front first pillar, and a rear second pillar between the left rear first pillar and the right rear first pillar. The distance between the left front first pillar and the left rear first pillar is L1, the distance between the right front first pillar and the right rear first pillar is L1, the distance between the left front first pillar and the front second pillar is L1, the distance between the right front first pillar and the front second pillar is L2, the distance between the left rear first pillar and the rear second pillar is L2, and the distance between the right rear first pillar and the rear second pillar is L2, where L1=L2.

[0041] This ensures that the distance between any two adjacent columns 12 along the circumferential direction of the chassis 11 is the same, making it easy to make the shape and size of multiple panels 13 the same. Multiple panels 13 can be formed by processing the same mold, and only a few different structures need to be processed separately, reducing the number of molds and lowering costs. In addition, the outer contour shape and size of multiple panels 13 are the same, which can improve the production efficiency of panels 13, and make the installation of the whole machine simpler and the after-sales maintenance more convenient.

[0042] In addition, the electrical control box is located on the right side of the lower cavity. The size of the electrical control box in the front-to-back direction is smaller than the distance between the first right front column and the first right rear column, which facilitates the installation of the electrical control box.

[0043] In some embodiments of this utility model, such as Figure 4 , Figure 5 , Figures 11-14 As shown, the two adjacent outer side walls of the chassis 11 are connected by a chamfered right angle surface. Along the width direction of the first column 121, the first column 121 includes a first plate 123, a second plate 124 and a third plate 125 connected in sequence. The first plate 123 and the second plate 124 form an angle with each other, and the second plate 124 and the third plate 125 form an angle with each other. The first plate 123 and the third plate 125 are located on the same side of the thickness direction of the second plate 124. The first plate 123 and the third plate 125 are respectively attached to the two outer side walls of the chassis 11, and the second plate 124 is attached to the chamfered right angle surface.

[0044] This facilitates the fit between the first column 121 and the chassis 11, improving the reliability of the fixation of the first column 121 and the chassis 11. In addition, the first column 121 has a first plate 123 and a third plate 125 located on the adjacent sides of the chassis 11, which facilitates the connection between the first column 121 located at the corner of the chassis and the two panels 13 located on the adjacent sides of the chassis 11.

[0045] In related technologies, existing heat pump air conditioners generally use a four-point guideless column support structure as the load-bearing foundation of the unit frame. During implementation, installers need to independently position and tighten the four corner columns of the unit. Due to the lack of a reference positioning device and guiding auxiliary mechanism, the actual assembly has the following defects: the spatial positioning accuracy of multiple columns is difficult to guarantee, easily resulting in large assembly errors, leading to excessive gaps at the connection between the top plate and side plates, affecting the consistency of the fit between the side plates and columns; the installation process requires repeated adjustments and corrections to the column verticality and spacing parameters, resulting in a long average installation time and significantly reducing assembly line efficiency. Current solutions mainly rely on manual experience for compensatory installation and have not yet formed a systematic structural optimization scheme.

[0046] In some embodiments of this utility model, such as Figure 4 , Figure 5 , Figure 11 and Figure 12 As shown, refer to Figure 13 and Figure 14 At least some of the columns 12 have a guide insertion structure 1211 at their bottom, and the chassis 11 has insertion holes 111 that mate with the guide insertion structure 1211. The guide insertion structure 1211 makes it easy for the columns 12 to be inserted into the insertion holes 111 of the chassis 11 for fixing during installation. Standardized processing enables the coordinated manufacturing of the insertion holes 111 on the columns 12 and the chassis 11, improving the positioning accuracy of the columns 12, reducing assembly errors, ensuring the assembly gap between the top cover assembly 2 and the panel 13, and avoiding repeated adjustments and corrections by operators, thus improving assembly efficiency.

[0047] For example, in Figure 1 and Figure 2 In the example shown, the bottom of the four first pillars 121 is provided with guide insertion structures 1211, and the chassis 11 is provided with insertion holes 111 that mate with the guide insertion structures 1211. This can better ensure the installation accuracy of the first pillars 121 at the four corners of the chassis 11, reduce assembly errors, ensure the assembly gap between the top cover assembly 2 and the panel 13, and avoid repeated adjustments and corrections by operators, thus improving assembly efficiency. The bottom of the second pillar 122 is not provided with guide insertion structures 1211, which simplifies the structure and processing technology of the second pillar 122 and improves production efficiency.

[0048] Optionally, the insertion hole 111 is formed by a stamping process.

[0049] In some embodiments of this utility model, such as Figure 8 and Figure 14As shown, the guide insertion structure 1211 includes a first segment 1212 and a second segment 1213. One end of the first segment 1212 is connected to the column 12, and the other end extends towards one side of the column 12 in the thickness direction. The first segment 1212 overlaps the base 11. One end of the second segment 1213 is connected to the end of the first segment 1212 away from the column 12, and the other end extends downward. The second segment 1213 is inserted into the insertion hole 111. By inserting the second segment 1213 into the insertion hole 111, the positioning between the column 12 and the base 11 is achieved. By having the first segment 1212 overlap the top of the base 11, the vertical movement of the column 12 can be limited, further improving the reliability of the column 12's fixation.

[0050] It is understandable that the length of the insertion hole 111 is greater than the width of the second segment 1213, and the width of the insertion hole 111 is greater than the thickness of the second segment 1213. This facilitates the insertion of the second segment 1213 into the insertion hole 111. The insertion hole 111 and the second segment 1213 are fitted with a clearance. When the column 12 is installed, the positional deviation is automatically compensated by the fit between the second segment 1213 and the insertion hole 111.

[0051] In some embodiments of this utility model, such as Figures 6-8 As shown, the lower end of the second segment 1213 extends at an angle away from the column 12, which makes the lower end of the second segment 1213 further away from the column 12, making it easier for the second segment 1213 to be inserted into the insertion hole 111 of the chassis 11. At the same time, the lower end of the second segment 1213 extends at an angle away from the column 12, which makes the second segment 1213 form an inclined segment, giving the second segment 1213 a better guiding effect, further facilitating the insertion of the second segment 1213 into the insertion hole 111.

[0052] In some embodiments of this utility model, such as Figures 6-8 As shown, the first segment 1212 is set horizontally, which makes it easier for the lower surface of the first segment 1212 to fit against the upper surface of the chassis 11, improving the reliability of the column 12 fixed on the chassis 11, better ensuring the installation accuracy of the first column 121 at the four corners of the chassis 11, reducing assembly errors, ensuring the assembly gap between the top cover assembly 2 and the panel 13, and avoiding repeated adjustments and corrections by the operator, thus improving assembly efficiency.

[0053] In some embodiments of this utility model, the angle between the first segment 1212 and the second segment 1213 is greater than or equal to 90 degrees. This facilitates increasing the distance between the lower end of the second segment 1213 and the column 12, making it easier for the second segment 1213 to be inserted into the insertion hole 111. At the same time, it allows the second segment 1213 to play a better guiding role, making it easier for the second segment 1213 to be inserted into the insertion hole 111 during the installation of the column 12.

[0054] In some embodiments of this utility model, the guide plug-in structure 1211 is one or multiple structures spaced apart along the width direction of the column 12. Thus, a reasonable number of guide plug-in structures 1211 can be set as needed, thereby facilitating the installation and positioning of the column 12, reducing assembly errors, ensuring the assembly gap between the top cover assembly 2 and the panel 13, and avoiding repeated adjustments and corrections by operators, thereby improving assembly efficiency.

[0055] For example, in Figure 4 and Figure 5 In the example shown, reference Figures 10-12 As shown, the two adjacent sidewalls at the four corners of the chassis 11 are connected by a chamfered right angle surface. Along the width direction of the first column 121, the first column 121 includes a first plate 123, a second plate 124 and a third plate 125 connected in sequence. The first plate 123 and the second plate 124 form an angle with each other, and the second plate 124 and the third plate 125 form an angle with each other. The first plate 123 and the third plate 125 are located on the same side of the thickness direction of the second plate 124. The guide plug-in structure 1211 is one and is provided on one side of the thickness direction of the second plate 124. The upper surface of the chassis 11 is provided with a plug-in hole 111 corresponding to the position of the chamfered right angle surface.

[0056] Of course, this utility model is not limited to this. There can also be two guide plug-in structures 1211, which can be respectively provided on the same side of the thickness direction of the first plate 123 and the third plate 125. Alternatively, there can be three guide plug-in structures 1211, which can be respectively provided on the same side of the thickness direction of the first plate 123, the second plate 124 and the third plate 125.

[0057] Optionally, the first plate 123, the second plate 124 and the third plate 125 can respectively fit into the two adjacent side walls at the corner of the chassis 11 and the chamfered straight surface to ensure the reliability of the fixation between the column 12 and the chassis 11.

[0058] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the guide plug-in structure 1211 and the column 12 are integral parts. The guide plug-in structure 1211 can be formed by cutting and bending a part of the column 12, which simplifies the assembly between the guide plug-in structure 1211 and the column 12 and improves the assembly efficiency.

[0059] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, for reference Figure 9 , Figure 13 and Figure 14At least some of the columns 12 have side edges 1214 bent towards the thickness direction on both sides in the width direction. The lower end of the side edge 1214 has a fixing ear 1215, which fits against the upper surface of the chassis 11 and is connected by fasteners. On the one hand, the side edge 1214 can enhance the structural strength of the column 12 and improve the reliability of the whole machine. On the other hand, it is convenient to set the fixing ear 1215 above the chassis 11 and connect it to the chassis 11 by fasteners.

[0060] For example, in Figure 4 and Figure 5 In the example described, the first column 121 has side edges 1214 on both sides in the width direction, which bend towards one side in the thickness direction of the first column 121. The lower end of each side edge 1214 has a fixing lug 1215, which fits against the upper surface of the chassis 11 and is connected by fasteners. Figure 2 As shown, the second column 122 has side edges 1214 on both sides in the width direction, but the lower end of the side edges 1214 of the second column 122 does not have a fixing lug 1215 structure. In addition, the side edges 1214 of the second column 122 are also provided with a first folded edge, which is used to fit with the inner surface of the panel 13 and is connected by fasteners.

[0061] Of course, the lower end of the first fold can also be provided with a fixing ear 1215 for connection with the chassis.

[0062] Furthermore, such as Figure 13 and Figure 14 As shown, one side surface of the column 12 in the thickness direction is in contact with the outer peripheral surface of the chassis 11, and the side 1214 is bent toward the inner side of the chassis 11. Thus, the column 12 and the chassis 11 can define a larger space for the receiving cavity, which facilitates the layout of the internal components of the heat pump air conditioner 100.

[0063] Understandably, the first plate 123 and the third plate 125 are fitted to the outer surfaces of the two adjacent side walls of the chassis 11, and the second plate 124 is fitted to the chamfered right angle surface between the two adjacent side walls. The ends of the first plate 123 and the third plate 125 facing away from each other are connected to side edges 1214. In addition, the upper end of the side wall of the chassis 11 is provided with an inwardly bent flange 112, and the fixing lug 1215 is fitted to the upper surface of the flange 112 and connected to the flange 112 by fasteners.

[0064] Optionally, the fixing ear 1215 and the column 12 are integral parts, wherein the fixing ear 1215 can be formed by bending the lower end of the side 1214 upward, thereby omitting the assembly process between the fixing ear 1215 and the column 12.

[0065] Of course, this utility model is not limited to this. The fixing ear 1215 and the column 12 can be separate machined parts and welded together, which can simplify the processing technology of the parts.

[0066] Furthermore, such as Figure 5 , Figure 10 and Figure 14 As shown, a reinforcing rib 1216 is provided at the connection between the fixing ear 1215 and the side 1214. A reinforcing rib 1216 is also provided on the fixing ear 1215. The reinforcing rib 1216 extends along the circumferential direction of the fastener, thereby enhancing the structural strength of the fixing ear 1215 and the connection strength between the fixing ear 1215 and the side 1214, and improving the reliability of the fixation between the column 12 and the chassis 11.

[0067] Optionally, panel 13 is connected to side 1214, thereby facilitating the connection between panel 13 and post 12.

[0068] In some embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 15 and Figure 16 As shown, the heat pump air conditioner 100 also includes a top cover assembly 2, which includes an air guide ring 21 and a motor bracket 22. The air guide ring 21 is connected to the upper end of the column 12 and the upper end of the panel 13. The air guide ring 21 can cover the upper open end of the receiving cavity. The air guide ring 21 has an air outlet 215, which can be an air outlet. The motor bracket 22 is located on one side of the air guide ring 21 in the vertical direction, such as the upper side or the lower side. The motor bracket 22 includes a motor mounting part 221 and a connecting arm 222. The motor mounting part 221 is opposite to the air outlet 215. One end of the connecting arm 222 is connected to the motor mounting part 221. There are multiple connecting arms 222 spaced apart along the circumferential direction of the motor mounting part 221. The other end of the connecting arm 222 is connected to the air guide ring 21.

[0069] By connecting the connecting arm 222 to the air guide ring 21, the motor bracket 22 can be fixed. The motor 23 can be fixed on the motor mounting part 221. The air outlet 215 can be equipped with a fan wheel 24. The motor 23 is connected to the fan wheel 24 to drive the fan wheel 24 to rotate.

[0070] In related technologies, the motor positioning accuracy of the air guide ring connection is poor, installation efficiency is low, and drainage is inadequate. The positioning accuracy of the motor bracket is difficult to guarantee, easily resulting in assembly errors exceeding ±3mm. This leads to inaccurate positioning of the motor bracket and air guide ring, affecting the fit between them and potentially causing the fan blades to scrape against the inner wall of the air guide ring after machine startup. Furthermore, the installation process requires repeated adjustments and corrections to the hole positions and spacing parameters of the motor bracket and air guide ring, resulting in significant time consumption and reduced assembly line efficiency. Due to the weight of the motor bracket and motor, the area around the holes in the air guide ring and motor bracket is prone to slope, leading to water accumulation and a risk of rust on bolts and nuts.

[0071] In this invention, along the vertical direction, the side of the air guide ring 21 facing the motor bracket 22 has multiple positioning grooves 212. These positioning grooves 212 are spaced apart along the circumferential direction of the air outlet 215 and correspond one-to-one with multiple connecting arms 222. The end of each connecting arm 222 facing away from the motor mounting part 221 is located within a positioning groove 212 and connected to the air guide ring 21. This allows the connecting arms 222 to be positioned using the positioning grooves 212, ensuring the installation accuracy of the motor bracket 22 and the air guide ring 21, preventing the impeller 24 from scratching the air guide ring 21, and facilitating the positioning and installation of the motor bracket 22 and the air guide ring 21 by installers, thus improving assembly efficiency.

[0072] Optionally, the connecting arm 222 of the motor bracket 22 is connected to the air guide ring 21 by fasteners such as screws or bolts.

[0073] For example, when the motor bracket 22 is located above the air guide ring 21, the upper surface of the air guide ring 21 has a positioning groove 212, and the end of the connecting arm 222 that is away from the motor mounting part 221 is located in the positioning groove 212, so as to achieve precise positioning of the air guide ring 21 and the motor bracket 22, avoid the impeller 24 from rubbing against the air guide ring 21, and improve the assembly efficiency of the air guide ring 21 and the motor bracket 22.

[0074] When the motor bracket 22 is located below the air guide ring 21, such as Figure 15 and Figure 16 As shown, the lower surface of the air guide ring 21 has a positioning groove 212. One end of the connecting arm 222 that is away from the motor mounting part 221 is located in the positioning groove 212, so as to realize the precise positioning of the air guide ring 21 and the motor bracket 22, avoid the impeller 24 from rubbing against the air guide ring 21, and improve the assembly efficiency of the air guide ring 21 and the motor bracket 22.

[0075] In some embodiments of this invention, the positioning groove 212 is formed by a portion of the air guide ring 21 recessed towards one side of the air guide ring 21 in the thickness direction. This simplifies the structure and processing technology of the air guide ring 21 and improves production efficiency.

[0076] Furthermore, the motor bracket 22 is located above the air guide ring 21, the opening of the positioning groove 212 faces upward, and a water guide hole 214 is provided on the bottom wall of the positioning groove 212. This allows water accumulated in the positioning groove 212 to be discharged through the water guide hole 214, preventing water accumulation in the positioning groove 212 and avoiding problems such as rusting of fasteners.

[0077] In some embodiments of this utility model, such as Figure 15 and Figure 16As shown, the air guide ring 21 has multiple positioning protrusions 211 on the side facing the motor bracket 22, and the multiple positioning protrusions 211 define multiple positioning grooves 212. Thus, in addition to forming the positioning grooves 212, the positioning protrusions 211 can also enhance the structural strength of the air guide ring 21 and improve the reliability of the air guide ring 21 in supporting the motor bracket 23.

[0078] In some embodiments of this utility model, such as Figure 15 and Figure 16 As shown, the motor bracket 22 is located below the air guide ring 21. The positioning protrusion 211 is formed by a portion of the air guide ring 21 protruding downwards. A groove is provided on the upper side of the air guide ring 21 corresponding to the position of the positioning protrusion 211, and a water guide hole 214 is provided on the bottom wall of the groove. This facilitates the setting of the positioning protrusion 211 and allows water accumulated in the groove to be discharged through the water guide hole 214, avoiding water accumulation in the groove and preventing problems such as rusting of fasteners.

[0079] Optionally, such as Figure 15 and Figure 16 As shown, the positioning protrusion 211 extends along the circumferential direction of the fastener used to connect the connecting arm 222 and the air guide ring 21. The positioning protrusion 211 may have an opening, that is, the positioning protrusion 211 is formed as an open ring, and the opening is located at the center of the positioning protrusion 211 facing the air outlet 215. For example, the positioning protrusion is formed as a U-shape, and the open opening of the U-shaped positioning protrusion 211 faces the center of the air outlet 215. This facilitates one end of the connecting arm 222 to extend into the positioning groove 212 through the opening of the positioning protrusion 211, so as to achieve a precise fit between the connecting arm 222 and the positioning groove 212.

[0080] In some embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 15 and Figure 16 As shown, the outer edge of the air guide ring 21 has a downwardly bent second fold 216. The second fold 216 extends along the circumferential direction of the air guide ring 21. The second fold 216 has an opening, which can be directly connected and fixed to the column 12. This facilitates the connection between the air guide ring 21 and the column 12, improves the reliability of the connection between the air guide ring 21 and the column 12, and thus improves the overall reliability of the heat pump air conditioner 100.

[0081] In some embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 15 and Figure 16As shown, there are two air guide rings 21 arranged along the length of the chassis 11, and two corresponding motor brackets 22. The second folded edges 216 of the two air guide rings 21 close to each other are fastened together. Of course, the second folded edges 216 of the two air guide rings 21 close to each other can also be welded together so that the two air guide rings 21 can be connected to each other to form a whole.

[0082] Of course, this utility model is not limited to this. The number of air guide rings 21 is not limited to two. There can be more air guide rings 21.
