Description

Technical Field

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

[0002] Existing air conditioner indoor units typically include a support frame, a heat exchanger, and a motor assembly, with both the heat exchanger and motor assembly mounted on the support frame. The motor assembly is usually located below and outside the heat exchanger. When disassembling or maintaining the motor assembly, it is usually necessary to first lift the heat exchanger from its installation position to provide operating space. However, due to the large size and weight of the heat exchanger, and the fact that the motor assembly is located at one end, when operating by a single person, lifting one end of the heat exchanger to create operating space will cause the other end to fall downwards due to gravity, resulting in an unstable state for the entire heat exchanger. This makes it difficult for the operator to simultaneously stabilize the heat exchanger and perform disassembly and assembly of the motor assembly, making single-person operation extremely difficult and posing a safety hazard. Utility Model Content

[0003] In view of the above problems, this utility model is proposed to provide an air conditioner indoor unit that overcomes or at least partially solves the above problems, and can solve the technical problems of heat exchanger lifting imbalance, difficult operation and safety risks when a single person maintains the motor assembly in existing air conditioner indoor units.

[0045] Figure 1This is a schematic structural diagram of an indoor unit of an air conditioner according to an embodiment of the present invention, as shown below. Figure 1 As shown, and refer to Figures 2 to 7 This utility model provides an indoor unit for an air conditioner. The indoor unit includes a housing 400, a lifting lug 600, a support frame 100, a heat exchanger 200, and a connector 300.

[0046] The outer casing 400 includes a front casing 430 and a rear casing 440. The support frame 100, heat exchanger 200, and connector 300 are all disposed within the rear casing 440. The front casing 430 is detachably disposed at the front opening of the rear casing 440. The front casing 430 is disposed at the front end of the support frame 100. The heat exchanger 200 is disposed on the support frame 100. The first end of the connector 300 is connected to the front part of the heat exchanger 200, and the second end of the connector 300 is detachably connected to the lifting lug 600. When the second end of the connector 300 is not connected to the lifting lug 600 (i.e., when the two are separated), the heat exchanger 200 is disposed on the support frame 100 (i.e., the lower end of the front part of the heat exchanger is located on the support frame). When the second end of the connector 300 is connected to the lifting lug 600, there is a gap between the lower end of the front part of the heat exchanger and the support frame 100.

[0047] Specifically, the indoor unit of the air conditioner also includes a motor assembly 500, which is disposed within the rear housing 440 and located at the end of the heat exchanger 200. The connector 300 is disposed at the middle position on the front side of the heat exchanger 200 or at one end away from the motor assembly 500.

[0048] When maintenance of the motor assembly 500 is required, first remove the front housing 430 from the rear housing 440, fully exposing the opening on the front side of the rear housing 440. The operator then reaches into the rear housing 440 through the front opening. Next, the operator manually lifts one end of the heat exchanger 200. Simultaneously or after lifting the heat exchanger 200, the operator locates the connector 300 installed at the front of the heat exchanger 200. The second end of the connector 300 is then attached to the lifting lug 600. At this point, under the upward pulling force of the connector 300, the lower front end of the heat exchanger 200 remains in the lifted position, thus creating a stable and reliable space between the lower front end of the heat exchanger 200 and the support frame 100 below. The operator then uses one hand to lift the other end of the heat exchanger 200 while using the other hand to remove the motor assembly 500.

[0049] This embodiment features a connector 300 at the front of the heat exchanger 200 and a lifting lug 600 on the front side of the upper part of the rear shell. When maintenance of the motor 510 is required, the operator connects the connector 300 to the lifting lug 600, thus securing one end of the heat exchanger 200 in a raised position. At this time, only one hand needs to be used to gently lift the other end of the heat exchanger 200 (the motor end), while the other hand can directly perform the disassembly and assembly of the motor assembly 500, significantly improving the efficiency and convenience of single-person maintenance. This embodiment effectively overcomes the imbalance problem of the other end sagging when one end of the heat exchanger 200 is lifted in the prior art, and eliminates the safety hazard of the heat exchanger 200 accidentally slipping.

[0050] like Figures 2 to 5 As shown, in some optional embodiments of this utility model, the heat exchanger 200 includes a first tube sheet 210, and a first connecting structure is provided on the upper side of the front part of the first tube sheet 210 to connect to the first end of the connector 300. In this embodiment, the first end of the connector 300 is connected to the first connecting structure.

[0051] like Figure 3 and Figure 5 As shown, in some optional embodiments of this utility model, the first connection structure is a connection hole.

[0052] In some optional embodiments of this utility model, the first connecting structure is a longitudinally extending connecting column, and the end of the connecting member is wound around the connecting column. That is, the connecting column extends along the length direction of the heat exchanger.

[0053] like Figure 3 and Figure 5 As shown, in some optional embodiments of this utility model, the connector 300 is a metal hook. The metal hook includes a connecting rod 311 and a first hook portion 312. One end of the connecting rod 311 is rotatably connected to the heat exchanger 200, and the other end of the connecting rod 311 is provided with a first hook portion 312, which is adapted to the lifting lug 600.

[0054] Specifically, one end of the connecting rod 311 is provided with a second hook 313, which is hooked in the connecting hole or wrapped around the connecting post. Alternatively, one end of the connecting rod is provided with a ring, which is fitted onto the connecting post. When maintenance of the motor 510 is required, the first hook of the metal hook is hung on the lifting lug, thereby allowing one end of the heat exchanger 200 to be stably raised.

[0055] In some optional embodiments of this utility model, the connector can also be a lifting rope. Specifically, the first end of the lifting rope passes through the connecting hole, or the first end of the lifting rope is wound around the connecting post. When it is necessary to maintain the motor 510, the second end of the lifting rope is tied to the lifting lug, so that one end of the heat exchanger 200 can be stably in a raised state.

[0056] like Figure 4 and Figure 5 As shown, in some optional embodiments of this utility model, a connecting plate 441 is provided at the top of the front opening of the rear shell 440, and a lifting lug 600 is formed on the connecting plate.

[0057] In this embodiment, the lifting lug is positioned at the top of the front opening of the rear shell, facilitating quick location of the lug and enabling connection of the connector 300 to the lug. Furthermore, the lug's placement at the top of the rear shell increases the lifting height of the heat exchanger. Additionally, the connecting plate 441 enhances the strength of the lug.

[0058] like Figure 4 and Figure 5 As shown, in some optional embodiments of this utility model, the lifting lug 600 is located on the side of the connecting plate 441 near the first tube plate 210.

[0059] Furthermore, a connecting port 4411 is formed on the upper part of the side of the connecting plate 441 near the first tube plate 210, and the connecting port 4411 is connected to the lifting lug 600.

[0060] In this embodiment, the above-described configuration makes it easier to connect the connector to the lifting lug.

[0061] like Figure 2 and Figure 4 As shown, in some optional embodiments of this utility model, the heat exchanger 200 further includes a heat exchange section 240, the first tube sheet 210 is located at the end of the heat exchange section 240, the heat exchange section 240 includes a first heat exchange segment, a second heat exchange segment and a third heat exchange segment, the first heat exchange segment and the second heat exchange segment are arranged at an angle, the first heat exchange segment is located in front of the second heat exchange segment, and the third heat exchange segment is located below the first heat exchange segment.

[0062] like Figure 2 , Figure 4 and Figure 6 As shown, in some optional embodiments of this utility model, the heat exchanger 200 further includes a second tube sheet 220, which is disposed opposite to the first tube sheet 210. Specifically, the first tube sheet 210 and the second tube sheet 220 are located on the left and right sides of the heat exchanger 200.

[0063] The indoor unit of the air conditioner also includes a motor assembly 500 and a cross-flow fan. The motor assembly 500 has a motor 510 and a motor housing 520; the motor assembly 500 is located on the outside of the second tube sheet 220. The cross-flow fan is located between the heat exchanger 200 and the support frame 100, and the cross-flow fan is connected to the output shaft of the motor 510.

[0064] Specifically, such as Figure 1As shown, the indoor unit of the air conditioner has an air inlet 401, an air outlet 402, and an air duct. The air duct connects the air inlet 401 and the air outlet 402. The motor 510 drives the cross-flow fan to rotate. Under the action of the cross-flow fan, indoor air enters the air duct inside the indoor unit through the air inlet 401 and exchanges heat with the heat exchanger 200 inside the air duct to form heat-exchanged air. The heat-exchanged air is blown into the indoor space through the air outlet 402.

[0065] In some optional embodiments of this utility model, the rear end of the heat exchanger 200 is rotatably mounted on the support frame 100 about a longitudinal axis. In this embodiment, the rear end of the heat exchanger 200 is rotatably mounted on the support frame 100, which facilitates lifting the front end of the heat exchanger 200.

[0066] In some optional embodiments of this utility model, the support frame 100 has two upward-facing grooves; the outer sides of the first tube plate 210 and the second tube plate 220 are provided with retaining shafts, each retaining shaft being inserted into a groove.

[0067] In this embodiment, a first retaining shaft is provided on the side of the first tube sheet 210 opposite to the second tube sheet 220, and a second retaining shaft is provided on the side of the second tube sheet 220 opposite to the first tube sheet 210. The two grooves are a first groove and a second groove, respectively. The first retaining shaft engages with the first groove, and the second retaining shaft engages with the second groove. Since the openings of the grooves face upwards, the retaining shafts can be installed into the corresponding grooves from top to bottom.

[0068] In this embodiment, each tube sheet is snapped into a corresponding groove in the support via a retaining pin. Since the heat exchanger 200 can rotate around the axis of the retaining pin, it facilitates the overall disassembly and installation of the heat exchanger 200.

[0069] In some optional embodiments of this utility model, the indoor unit of the air conditioner is a wall-mounted air conditioner indoor unit.

[0070] like Figure 1 As shown, in some optional embodiments of this utility model, the indoor unit of the air conditioner is an embedded indoor unit of the air conditioner.

[0071] like Figure 1 As shown, in some optional embodiments of this utility model, the front shell 430 is provided with an air inlet 401 and an air outlet 402, with the air inlet 401 located above the air outlet 402.

[0072] like Figure 1 As shown, in some optional embodiments of this utility model, a guide plate 410 is rotatably installed at the air outlet 402 to adjust the opening and closing of the air outlet 402 and the air outlet angle. A sealing plate 420 is rotatably installed at the air inlet 401 for opening or closing the air inlet 401.

[0073] like Figure 6As shown, in some optional embodiments of this utility model, the motor housing 520 includes a motor base 521 and a motor cover 522. The motor base 521 has an insertion port for inserting a motor 510, with the insertion port facing forward; the motor cover 522 is detachably mounted at the insertion port of the motor base 521, and the lower part of the motor cover 522 is movably connected to the lower part of the motor base 521 via a second connecting structure 523, so as to at least allow the motor cover 522 to rotate relative to the motor base 521 about a longitudinally extending axis.

[0074] In this embodiment, since the lower part of the motor cover 522 is movably connected to the lower part of the motor base 521 through the second connecting structure 523, and the insertion port of the motor base 521 faces forward, the motor cover 522 can rotate around the longitudinal axis to achieve "door-type opening and closing", which significantly reduces the difficulty of assembly and disassembly.

[0075] In addition, the motor cover 522 remains connected to the motor base 521 during the rotation and opening process, avoiding the risk of detachment caused by the complete separation of the motor cover 522 and the motor base 521, thus balancing maintenance efficiency and operational safety.

[0076] In some optional embodiments of this utility model, the second connecting structure 523 is a connecting piece, which is a flexible piece or an elastic piece. Specifically, the connecting piece is made of a flexible material (such as silicone or plastic) or an elastic metal sheet, and its two ends are respectively fixed to the lower part of the motor base 521 and the motor cover 522.

[0077] In some optional embodiments of this utility model, the second connecting structure 523 includes multiple connecting strips, one end of each connecting strip being connected to the motor base 521 and the other end being connected to the motor cover 522. Specifically, the lower part of the motor base 521 and the lower part of the motor cover 522 are movably connected together by multiple connecting strips. These connecting strips are made of flexible or elastic materials. Multiple independent connecting strips (such as nylon strips, metal springs, or plastic strips) are arranged in parallel, with both ends of each connecting strip fixed to the motor base 521 and the motor cover 522, respectively. In this embodiment, when a single connecting strip breaks, the remaining connecting strips can still maintain structural integrity, preventing the motor cover 522 from suddenly detaching. The multiple connecting strips evenly distribute the tensile and torsional forces during opening and closing, reducing stress concentration at individual connection points.

[0078] In some optional embodiments of this utility model, the second connecting structure 523 is a connecting wall with a thickness of 0.2mm to 1mm. Specifically, the thickness of the connecting wall is any one of 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, and 1mm. This connecting wall is similar to the connection structure between the box body and the lid of a cardboard box in the prior art. Due to the thinness of the connecting wall, the lower part of the motor base 521 and the lower part of the motor cover 522 can be movably connected together through the connecting wall. In this embodiment, using a connecting wall as the second connecting structure 523 allows the motor base 521, the motor cover 522, and the second connecting structure 523 to be integrally formed, thereby reducing the overall processing and manufacturing difficulty of the motor box 520 and reducing production costs. The thin-walled structure reduces weight while ensuring strength, which is in line with the trend of lightweight air conditioners.

[0079] In some optional embodiments of this utility model, the distance between the part of the second connecting structure 523 connected to the motor base 521 and the part connected to the motor cover 522 is within 5mm.

[0080] Specifically, the distance between the part of the second connecting structure 523 that is connected to the motor base 521 and the part that is connected to the motor cover 522 can be any one of 1mm, 2mm, 3mm, 4mm, or 5mm.

[0081] In this embodiment, the short-pitch connection significantly shortens the lever arm when the motor cover 522 rotates open and closes, making the relative movement trajectory of the motor cover 522 and the motor base 521 more controllable. This allows for quick and automatic alignment with the fixed point when closing, reducing the number of manual adjustments. Simultaneously, the compact connection spacing effectively suppresses minor displacement of the motor cover 522 under vibration or external force, ensuring a long-term tight fit between the two and preventing abnormal noises or loosening caused by misalignment. This further enhances the structural stability and service life of the motor housing 520.

[0082] Therefore, by controlling the distance between the connection parts of the second connection structure 523 between the motor base 521 and the motor cover 522 to within 5mm, this embodiment significantly improves the alignment accuracy and assembly efficiency of the motor base 521 and the motor cover 522.

[0083] like Figure 6 As shown, in some optional embodiments of this utility model, the motor base 521, the motor cover 522, and the second connecting structure 523 are integrally formed from the same material.

[0084] This embodiment uses the same material to integrally mold the motor base 521, motor cover 522 and second connecting structure 523, eliminating the risk of thermal expansion differences and stress concentration at the interface of dissimilar materials. This significantly improves the overall structural strength and stability of the motor box 520, while simplifying the overall manufacturing process of the motor box 520 and reducing assembly errors.

[0085] In some optional embodiments of this utility model, the motor base 521, the motor cover 522, and the second connecting structure 523 are made of polypropylene.

[0086] like Figure 6 As shown, in some optional embodiments of this utility model, the upper part of the motor base 521 is snapped into the upper part of the motor cover 522. In this embodiment, the upper part of the motor base 521 and the upper part of the motor cover 522 are connected together by a snap-fit ​​structure 524. This snap-fit ​​structure 524 can be locked without tools, significantly shortening assembly time. In addition, the snap-fit ​​design supports non-destructive disassembly and assembly, facilitating later maintenance or replacement of the motor 510, and improving the user experience.

[0087] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
