Description

Technical Field

[0001] Embodiments of the present invention relate to the field of cross-flow fans. More specifically, the present invention relates to an installation structure for a cross-flow fan and a cross-flow fan. Background Art

[0002] As a key component in modern household electrical appliances, cross-flow fans are applied in multiple fields such as air conditioners, air purifiers, and fans. The performance of cross-flow fans not only directly affects the overall operating efficiency of the equipment but also is a key factor determining the user experience. Currently, external rotor motors are increasingly favored due to their compact structure and excellent heat dissipation performance and are widely used in cross-flow fans.

[0003] However, for the installation structure between the adapter structure of the air duct housing of a traditional cross-flow fan and the stator of the external rotor motor, most are bolt connections. Although this method can fix the stator to a certain extent, its installation process is relatively complex and there is a risk of loosening. In addition, the stator generates vibration and noise during the operation of the fan, which not only affects the performance of the applied equipment but also reduces the user experience. Summary of the Utility Model

[0004] To solve one or more of the above-mentioned technical problems, the present utility model provides a cross-flow fan and its installation mechanism, which can reduce the vibration between the stator and the adapter structure of the cross-flow fan, not only being beneficial to improving the stability during the operation of the equipment but also reducing noise and enhancing the user experience.

[0005] In a first aspect, according to the present utility model, it provides an installation mechanism for a cross-flow fan.

[0006] An installation structure for a cross-flow fan, which is used to fix the stator of the external rotor motor of the cross-flow fan on the adapter structure of the air duct housing of the cross-flow fan. The installation structure includes: a plurality of accommodation grooves formed on the adapter structure and arranged at intervals along the circumference of the stator; a plurality of elastic buffer members having clamping grooves, which are provided between the stator and the adapter structure and are individually inserted into each of the accommodation grooves; and a plurality of clamping protrusions arranged at intervals along the circumference on the stator and individually inserted into the clamping grooves of each of the elastic buffer members.

[0007] Furthermore, a first material-reducing through-hole and a second material-reducing through-hole are formed on each of the elastic buffer members. In any one of the elastic buffer members, the first material-reducing through-hole and the second material-reducing through-hole are symmetric with respect to the clamping groove and are distributed at intervals along the circumference of the stator.

[0008] Further, the cross-sections of the first subtractive through hole and the second subtractive through hole are both rectangular, and the central axes of the first subtractive through hole and the second subtractive through hole are both perpendicular to the axis of the stator and intersect or coincide with the radial direction of the stator.

[0009] Furthermore, each of the elastic buffer components is provided with an extended-range opening on a side away from the stator.

[0010] Furthermore, the extended-range opening is provided in plurality, and the plurality of extended-range openings are evenly distributed on the elastic buffer along the circumferential direction of the stator.

[0011] Furthermore, an outer contour of a cross section of the accommodating groove along the radial direction of the stator is the same as an outer contour of a cross section of the elastic buffer member along the radial direction of the stator, and both are rectangular.

[0012] Further, a cross section of the clamping protrusion along the radial direction of the stator is the same as a cross section of the clamping groove along the radial direction of the stator, and both are rectangular.

[0013] Furthermore, the transition structure is provided with an escape space for accommodating the stator conductor of the stator, or an opening for allowing the stator conductor of the stator to pass through the transition structure.

[0014] Furthermore, the elastic buffer is made of rubber or silicone.

[0015] In a second aspect, according to the present invention, a cross-flow blower is provided, which includes the mounting structure described in the first aspect of the present invention.

[0016] The installation structure described above not only realizes the clamping of multiple elastic buffers in the transition structure by opening multiple accommodating grooves on the transition structure of the air duct housing and using the multiple accommodating grooves to accommodate multiple elastic buffers, but also realizes the clamping of the stator in the elastic buffer by reserving clamping grooves on each elastic buffer and using the clamping grooves of each elastic buffer to accommodate multiple clamping protrusions provided on the stator. Through the aforementioned clamping method, the positioning and installation of the stator in the cross-flow fan can be completed easily and quickly. Compared with bolt connection, this not only has the advantages of simple installation process and high reliability, but also absorbs or reduces the vibration and noise generated by the stator during operation through the elastic buffer, thereby easily improving the performance of the application equipment and the user experience.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0025] In a first aspect, according to the present invention, a mounting mechanism for a cross-flow blower is provided.

[0026] Reference Figure 1 As a key component in modern household appliances, the crossflow fan is used in many fields such as air conditioners, air purifiers, and fans. The installation mechanism of the crossflow fan is mainly used to fix the stator 1 of the outer rotor motor on the adapter structure 3 of the air duct housing 2 of the crossflow fan.

[0027] Reference Figure 2 and Figure 3, the mounting structure includes a plurality of receiving grooves 32 formed on the adapter structure 3, and the plurality of receiving grooves 32 are arranged at intervals along the circumferential direction of the stator 1. The mounting structure further includes a plurality of elastic buffer members 4 provided between the stator 1 and the adapter structure 3 and individually inserted into each of the receiving grooves 32. Each of the elastic buffer members 4 should be made of a highly elastic material such as rubber or silica gel. Each of the elastic buffer members 4 has a clamping groove 41, and the mounting structure further includes clamping protrusions 42 arranged at intervals along the circumferential direction on the stator 1 and individually inserted into the clamping grooves 41 of each of the elastic buffer members 4.

[0028] Based on this, the mounting structure not only realizes the clamping of the plurality of elastic buffer members 4 in the adapter structure 3 by providing a plurality of receiving grooves 32 on the adapter structure 3 of the air duct housing 2 and using the plurality of receiving grooves 32 to accommodate the plurality of elastic buffer members 4, but also realizes the clamping of the stator 1 in the elastic buffer members 4 by providing clamping grooves 41 on each of the elastic buffer members 4 and using the clamping grooves 41 of each of the elastic buffer members 4 to accommodate the plurality of clamping protrusions 42 provided on the stator 1. Through the aforementioned clamping method, the positioning and installation of the stator 1 in the cross-flow fan can be easily and quickly completed. Compared with bolt connection, this not only has the advantages of simple installation process and high reliability, but also absorbs or reduces the vibration and noise generated by the stator 1 during operation through the elastic buffer members 4, thereby being easy to improve the performance of the application equipment and the user experience.

[0029] Preferably, referring to Figure 3 , Figure 4 and Figure 5 , a first material-removing through-hole 5 and a second material-removing through-hole 6 are provided on each elastic buffer member 4. In any one of the elastic buffer members 4, the first material-removing through-hole 5 and the second material-removing through-hole 6 are both symmetric about the clamping groove 41 and are distributed at intervals along the circumferential direction of the stator 1. Through the arrangement of the first material-removing through-hole 5 and the second material-removing through-hole 6, it not only has a weight-reducing effect, but also can further enhance the vibration absorption ability of the elastic buffer member 4 and reduce the vibration and noise generated by the cross-flow fan during use again, improving the user experience.

[0030] As an example, the first material-removing through-hole 5 and the second material-removing through-hole 6 can be set as through-holes with the same shape and structure. Preferably, the cross-sections of the first material-removing through-hole 5 and the second material-removing through-hole 6 are both rectangular, and the central axes of the first material-removing through-hole 5 and the second material-removing through-hole 6 are both perpendicular to the central axis of the stator 1 and intersect or coincide with the central axis of the stator 1. Thereby, the vibration absorption ability of the elastic buffer member 4 can be improved again, further reducing the vibration and noise generated by the cross-flow fan during use.

[0031] As an example, one or more range-extending openings 43 are provided on the side of each elastic buffer 4 away from the stator 1. When the range-extending openings 43 are provided in plurality, the plurality of range-extending openings 43 are evenly distributed on the elastic buffer 4 along the circumference of the stator 1. Preferably, the plurality of range-extending openings 43 are evenly spaced and distributed between the first material-reducing through hole 5 and the second material-reducing through hole 6. The aforementioned one or more range-extending openings 43 are used to enhance the elastic deformation degree of the elastic buffer 4 in the radial direction of the stator 1, so as to further enhance the vibration absorption capacity of the elastic buffer 4.

[0032] As an example, the outer contour of the cross section of the accommodating groove 32 along the radial direction of the stator 1 is substantially the same as the outer contour of the cross section of the elastic buffer 4 along the radial direction of the stator 1, and both are rectangular. This matching method ensures that the elastic buffer 4 can be accurately and tightly installed in the transition structure 3, especially the accommodating groove 32, thereby not only improving the accuracy and efficiency of installation, but also enhancing the stability and firmness of the elastic buffer 4 in the transition structure 3.

[0033] As an example, the cross section of the clamping protrusion 42 along the radial direction of the stator 1 is substantially the same as the cross section of the clamping groove 41 along the radial direction of the stator 1, and both are rectangular. This matching method ensures that the stator 1 can be accurately and tightly clamped into each elastic buffer 4 at the same time, thereby not only improving the accuracy and efficiency of installation, but also enhancing the stability and firmness of the stator 1 in each elastic buffer 4.

[0034] Reference Figure 2 and Figure 3 The transfer structure 3 has an escape space 31 for accommodating the stator wire of the stator 1, or an opening for allowing the stator wire of the stator 1 to pass through the transfer structure 3. The setting of the escape space 31 or the opening can provide an escape space 31 or an opening for the stator 1 wire, making the wiring more flexible and facilitating the positioning and adjustment of the wire during installation and maintenance.

[0035] In an embodiment not shown, a cross flow fan is also provided, which includes the above-mentioned mounting structure. The beneficial effects of the cross flow fan are specifically referred to above and will not be repeated here.
