Description

Technical Field

[0001] This utility model relates to the field of cross-flow fan installation technology, and in particular to an internal air conditioning installation structure for a cross-flow fan. Background Technology

[0002] As people's living standards continue to improve, air conditioners, as important devices for regulating indoor temperature, humidity and air quality, have been widely used in homes, offices and commercial spaces. Among the many components of an air conditioner, the cross-flow fan, due to its unique structure and good air delivery performance, has become a key component in the indoor unit to achieve air circulation.

[0003] When in use, the working principle of a cross-flow fan is that the rotation of the cross-flow impeller draws airflow from the open part of the impeller into the blade grid, through the inside of the impeller body, and out into the volute from the other side of the blade grid, thus forming the working airflow and completing the work of air conditioning to discharge cold and hot air.

[0004] Currently available cross-flow fans on the market require installation by first placing them inside the air conditioner casing and then plugging the rotor connector of the cross-flow fan into the air conditioner. However, since the rotor and the casing are integrated, the entire rotor needs to be replaced if it is damaged. This not only makes disassembly more troublesome but also increases processing costs, thus failing to meet the needs of users. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an internal air conditioning installation structure for a cross-flow fan, aiming to improve the problem that it is inconvenient to disassemble and replace the rotor of the cross-flow fan during long-term use in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an internal installation structure for an air conditioner using a cross-flow fan, comprising a cylindrical body, a circular ring fixedly connected to the right end of the cylindrical body, multiple limiting blocks fixedly connected at equal intervals around the right side of the circular ring, a hollow disk fixedly connected to the right side of the circular ring, multiple limiting grooves fixedly connected at equal intervals around the left side of the hollow disk, a connecting shaft fixedly connected to the inner center of the hollow disk, the left end of the connecting shaft penetrating the circular ring, a magnetic ring disposed inside the hollow disk, a stator body disposed inside the magnetic ring, the stator body being magnetically connected to the inside of the magnetic ring, an inner rotor disposed outside the stator body, and a disassembly mechanism disposed outside the stator body.

[0007] With the above technical solution, the connecting shaft is inserted into the shaft groove. At this time, the stator body will be completely inside the hollow disk. Since the magnetic ring is magnetically connected to the outside of the stator body, disassembly and installation can be carried out quickly.

[0008] As a further description of the above technical solution:

[0009] The disassembly mechanism includes a housing, which is located on the outside of the stator body. The right end of the stator body has multiple grooves, and bolts are threaded into the grooves. The left end of the bolts passes through the grooves and the housing in sequence. A clamping plate is fixedly connected to the top of the housing.

[0010] With the above technical solution, when it is necessary to inspect the stator body inside the housing, simply loosen the bolts to release the restriction on the housing, and then remove the housing from the outside of the stator body, thereby improving the practicality of the device.

[0011] As a further description of the above technical solution:

[0012] The magnetic ring has multiple buckles fixedly connected at equal intervals around its left end, and the hollow disc has multiple slots at equal intervals around its inner side, with each buckle engaging with its corresponding slot.

[0013] The above technical solutions can further improve the overall stability of the device.

[0014] As a further description of the above technical solution:

[0015] The disassembly mechanism also includes a connector, which is located on the right side of the stator body and is electrically connected to the connector.

[0016] Through the above technical solution, the connector can easily connect the stator body to the external air conditioner, and the external air conditioner can control the operation of the stator body through the connector.

[0017] As a further description of the above technical solution:

[0018] The disassembly mechanism also includes a mounting slot, which is fixedly connected to the rear side of the housing.

[0019] The above technical solution allows for the rapid installation of the cross-flow fan inside the air conditioner casing.

[0020] As a further description of the above technical solution:

[0021] A rubber pad is fixedly connected to the right side of the outer wall of the stator body, and the size of the rubber pad matches the size of the stator body.

[0022] The above technical solution can further reduce noise generation between connection structures, thereby further improving the practicality of the device.

[0023] As a further description of the above technical solution:

[0024] The plurality of limiting blocks are respectively engaged with the corresponding limiting grooves, and the size of the plurality of limiting blocks is respectively matched with the internal size of the corresponding limiting grooves.

[0025] The above technical solution allows the hollow disk to be placed more stably, thus not affecting the subsequent normal operation of the device.

[0026] As a further description of the above technical solution:

[0027] A shaft groove is provided in the middle of the left end of the stator body, and multiple heat dissipation holes are provided at equal intervals around the left end of the stator body. The right end of the connecting shaft passes through the shaft groove.

[0028] The above technical solution allows the stator body to be quickly installed on the cylinder, and the heat dissipation holes can quickly dissipate the heat generated by the stator body during operation, thereby improving the overall lifespan of the device.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the connecting shaft is inserted into the shaft groove, at which point the stator body is completely inside the hollow disk. Since the magnetic ring is magnetically connected to the outside of the stator body, disassembly and installation can be carried out quickly. Compared with the existing cross-flow stator, the volume can be made smaller, thereby increasing the torque of the stator body to reduce noise generation and thus meet the needs of users.

[0031] 2. In this utility model, the stator body can be protected by the housing. When it is necessary to inspect the stator body inside the housing, simply loosen the bolts to release the restriction on the housing, and then remove the housing from the outside of the stator body, thereby improving the practicality of the device.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Reference Figure 2 , Figure 3 and Figure 5 This utility model provides an embodiment of an air conditioner internal installation structure for a cross-flow fan, comprising a cylindrical body 1, a circular ring 3 fixedly connected to the right end of the cylindrical body 1, a plurality of limiting blocks 4 fixedly connected at equal intervals around the right side of the circular ring 3, a hollow disk 5 fixedly connected to the right side of the circular ring 3, a plurality of limiting grooves 6 fixedly connected at equal intervals around the left side of the hollow disk 5, a connecting shaft 7 fixedly connected to the inner center of the hollow disk 5, the left end of the connecting shaft 7 penetrating the circular ring 3, a magnetic ring 8 disposed inside the hollow disk 5, a stator body 11 disposed inside the magnetic ring 8, the stator body 11 being magnetically connected to the inside of the magnetic ring 8, and an inner rotating part disposed on the outer side of the stator body 11. The stator body 11 has a disassembly mechanism 2 on its outer side. Multiple limiting blocks 4 are engaged with corresponding limiting grooves 6. The size of the multiple limiting blocks 4 matches the size of the corresponding limiting grooves 6. A shaft groove 13 is opened in the middle of the left end of the stator body 11. Multiple heat dissipation holes 12 are equidistantly opened around the left end of the stator body 11. The right end of the connecting shaft 7 passes through the shaft groove 13. There is an air gap between the stator body 11 and the magnetic ring 8. The air gap between the two is 0.2-2mm. In this embodiment, the iron core inside the stator body 11 can be selected as a twelve-slot ten-pole or twelve-slot fourteen-pole structure.

[0041] Specifically, during the assembly process, the connecting shaft 7 on the cylinder 1 is first inserted into the shaft groove 13 on the stator body 11. After this action is completed, the stator body 11 will completely enter the internal space of the hollow disk 5. At the same time, the limiting block 4 on the ring 3 will accurately insert into the corresponding limiting groove 6. Since the magnetic ring 8 and the outside of the stator body 11 are connected by magnetic attraction, the disassembly and installation process of the entire device becomes very quick and convenient. Compared with the existing cross-flow fans, this design allows the volume to be further reduced, thereby effectively increasing the torque of the stator body 11 to reduce noise generation and better meet the needs of users.

[0042] Reference Figure 1 , Figure 2 and Figure 5 The disassembly mechanism 2 includes a housing 201, which is disposed on the outside of the stator body 11. Multiple grooves 202 are provided on the right end of the stator body 11. Bolts 203 are threaded inside the grooves 202. The left end of the bolts 203 passes through the grooves 202 and the housing 201 in sequence. A clamping plate 204 is fixedly connected to the top of the housing 201. The disassembly mechanism 2 also includes a mounting groove 206, which is fixedly connected to the rear side of the housing 201.

[0043] Specifically, during the installation of the cylinder 1 inside the air conditioner, the housing 201 is first fitted onto the outside of the stator housing 11. Then, the bolts 203 are screwed into the corresponding grooves 202 in sequence, thus completing the installation of the housing 201. Subsequently, the mounting groove 206 on the housing 201 is inserted into the connecting structure inside the air conditioner housing. Through this operation, the installation of the entire cross-flow fan can be completed. The entire installation process is designed to be quite simple, thus greatly improving the practicality of the device.

[0044] Reference Figure 3 and Figure 4 Multiple buckles 9 are fixedly connected at equal intervals around the left end of the magnetic ring 8, and multiple slots 10 are equally spaced around the inner side of the hollow disk 5, with the multiple buckles 9 engaging with the corresponding slots 10 respectively.

[0045] Specifically, the stability of the stator body 11 during operation can be further improved by the interlocking of the buckle 9 and the slot 10.

[0046] Reference Figure 1 The disassembly mechanism 2 also includes a connector 205, which is located on the right side of the stator body 11 and is electrically connected to the connector 205.

[0047] Specifically, the stator body 11 can be easily connected to an external air conditioner via connector 205, and the external air conditioner can control the operation of the stator body 11 via connector 205.

[0048] Reference Figure 5 A rubber pad 15 is fixedly connected to the right side of the outer wall of the stator body 11, and the size of the rubber pad 15 matches the size of the stator body 11.

[0049] Specifically, the rubber pad 15 can further reduce noise generation between the connecting structures.

[0050] Working principle: When using this cross-flow fan, first insert the connecting shaft 7 on the cylinder 1 into the shaft groove 13 on the stator body 11. At this time, the stator body 11 will be completely inserted into the hollow disk 5, and the limiting block 4 on the ring 3 will be inserted into the corresponding limiting groove 6, thus completing the overall assembly. Since the magnetic ring 8 is magnetically connected to the outside of the stator body 11, disassembly and installation can be carried out quickly. Compared with the existing cross-flow fan stator, the volume can be made smaller, thereby increasing the torque of the stator body 11. With the rubber pad 15 on the outside of the stator body 11, the noise generation can be reduced, thus meeting the needs of users.

[0051] Furthermore, when it is necessary to install the cylinder 1 into the air conditioner, first, the housing 201 is fitted onto the outside of the stator body 11, and then the bolts 203 are screwed into the corresponding grooves 202 in sequence to complete the installation of the housing 201. Then, the mounting groove 206 on the housing 201 is inserted into the connecting structure in the air conditioner housing to complete the installation of the cross-flow fan. This operation is relatively simple, thereby improving the practicality of the device.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
