Description

Technical Field

[0001] The present invention relates to the technical field of household electrical appliances, and in particular to a mounting structure and an air supply device. Background Art

[0002] A heater is a common air supply device that can blow out warm air to keep users warm and is widely used in daily life. The heater mainly includes a shell and a grille. The grille is installed on the shell to form an air outlet. However, due to problems such as material and fitting tolerance, gaps are prone to appear at the fitting point between the grille and the shell. After the grille is assembled to the shell, unevenness is prone to occur at the fitting point between the two, which affects the appearance of the whole machine and leads to a poor user experience. Summary of the invention

[0003] In view of this, the present invention provides a mounting structure and an air supply device to solve the problem of gaps and unevenness at the joints between the existing heater grille and the housing.

[0004] In a first aspect, the present invention provides a mounting structure applied to an air supply device, wherein the air supply device comprises a housing and a grille, and the mounting structure comprises:

[0006] The drop fit structure comprises an outer edge of the shell and an outer edge of the grille, and the outer edges of the shell and the grille are in different planes.

[0007] Beneficial effect: The mounting structure of the present invention is applied to an air supply device, and the mounting structure includes an inclined matching structure and a drop matching structure. The cross section of the inclined matching structure along the thickness direction of the shell is set at an angle with the thickness direction of the shell, and the outer end of the inclined matching structure is closer to the outer wall of the shell than the inner end. By setting the inclined matching structure, even if there is a certain dimensional tolerance between the outer wall of the grille and the inner wall of the shell, when the grille is assembled into the shell, the outer wall of the grille will fit tightly against the inner wall of the shell, thereby eliminating the obvious gap between the two. In addition, by setting the drop matching structure, that is, the outer edge of the shell and the outer edge of the grille are in different planes, so that the edge where the shell and the grille match is always the outer edge of the shell or the outer edge of the grille, and the outer edge of the shell and the outer edge of the grille can ensure flatness during processing, so that the matching part of the shell and the grille is flatter, thereby improving the appearance of the whole machine and enhancing the user experience.

This inclined matching structure is relatively simple in structure, easy to manufacture, conducive to reducing costs, and easy to install. Moreover, the range of the inclination angle α of the first inclined surface and the second inclined surface relative to the thickness direction of the shell is 5°-15°. The first inclined surface and the second inclined surface within the above inclination angle range can ensure that the gap between the shell and the grille is eliminated, and it is easy to manufacture.

[0014] In an optional embodiment, the outer edge of the shell is placed outside the outer edge of the grille.

[0015] Beneficial effect: According to the installation structure of the present invention, after the outer shell and the grille are assembled, the outer edge of the outer shell is placed outside the outer edge of the grille, so that the outer edge of the head of the whole machine is the outer edge of the outer shell, and the outer edge of the outer shell can ensure flatness during processing, thereby simplifying the operation and improving assembly efficiency.

[0016] In an optional implementation, a distance L between an outer edge of the housing and an outer edge of the grille is less than or equal to 1 mm.

[0017] Beneficial effect: In the installation structure of the present invention, the distance L between the outer edge of the shell and the outer edge of the grille is less than or equal to 1 mm, thereby ensuring that after the grille is assembled to the shell, the outer edge of the shell is placed outside the outer edge of the grille, ensuring the flatness of the matching point between the grille and the shell, and then ensuring the flatness of the end face of the entire machine head, which is also conducive to reducing the difficulty of assembly.

[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0051] Combine the following Figure 1-Figure 7 , describing the embodiments of the mounting structure and air supply device of the present invention.

[0052] According to an embodiment of the present invention, a mounting structure is provided, which is applied to an air supply device, wherein the air supply device includes a shell 1 and a grille 2, and the mounting structure includes: an inclined fitting structure and a drop fitting structure, the inclined fitting structure is arranged on the inner wall of the shell 1 and the outer wall of the grille 2, the cross-section of the inclined fitting structure along the thickness direction of the shell 1 is arranged at an angle to the thickness direction of the shell 1, and the outer end 301 of the inclined fitting structure is closer to the outer wall of the shell 1 than the inner end 302; the drop fitting structure includes the outer edge of the shell 1 and the outer edge of the grille 2, and the outer edges of the shell 1 and the grille 2 are in different planes.

[0053] This installation structure is applied to an air supply device, specifically, to realize the installation of the housing 1 and the grille 2 in the air supply device. The installation structure is provided with an inclined matching structure, so that even if there is a certain dimensional tolerance between the outer wall of the grille 2 and the inner wall of the housing 1, when the grille 2 is assembled into the housing 1, the outer wall of the grille 2 will also fit the inner wall of the housing 1, thereby eliminating the obvious gap between the two. In addition, by providing a drop matching structure, that is, the outer edge of the housing 1 and the outer edge of the grille 2 are in different planes, so that the edge where the housing 1 and the grille 2 match is always the outer edge of the housing 1 or the outer edge of the grille 2, and the outer edge of the housing 1 and the outer edge of the grille 2 can ensure flatness during processing, so that the matching part of the housing 1 and the grille 2 is flatter, thereby improving the appearance of the whole machine and enhancing the user experience.

[0054] The mounting structure of this embodiment is used for an air supply device, such as a heater, a fan, etc. The air supply device has a head, which includes a shell 1 and a grille 2. The grille 2 is assembled with the shell 1 to form an internal accommodation space. The fan blades, motor and other components of the air supply device are arranged in the accommodation space. Figure 1 As shown. One end of the housing 1 is an open end, and the grille 2 is assembled at the open end, and the grille 2 is located on the air outlet side of the housing 1, and the grille 2 is assembled with the housing 1 through a mounting structure. The shapes of the housing 1 and the grille 2 are not limited. In this embodiment, the housing 1 is a rectangular parallelepiped, and the four corners of the housing 1 have a rounded design, and the shape and size of the grille 2 match the housing 1.

[0055] like Figure 2 As shown, the inclined matching structure is arranged on the inner wall of the housing 1 and the outer wall of the grille 2, and the cross section of the inclined matching structure along the thickness direction of the housing 1 is arranged at an angle with the thickness direction of the housing 1, so as to Figure 2 Taking the viewing angle as an example, the vertical direction is the thickness direction of the housing 1 (arrow a-a' direction), and the inclined matching structure as a whole forms an outwardly open structure. The cross section of the inclined matching structure along the thickness direction of the housing 1 forms an angle α with the thickness direction of the housing 1. In this embodiment, the angle α is an acute angle.

[0056] The inclined fitting structure has an outer end 301 and an inner end 302. Figure 2Taking the perspective as an example, the outer end 301 is the upper end of the inclined matching structure, and the inner end 302 is the lower end of the inclined matching structure. It can be understood that the inner wall of the shell 1 and the outer wall of the grille 2 are circumferentially matched on the horizontal plane, so the inclined matching structure is also a circumferential structure, and the outer end 301 and the inner end 302 of the inclined matching structure are both circular lines. The outer end 301 of the inclined matching structure is closer to the outer wall of the shell 1 than the inner end 302 to form an open structure. When installing the grille 2, Figure 1 Taking the perspective as an example, the grille 2 is installed on the housing 1 from top to bottom. This inclined matching structure can facilitate the assembly of the grille 2 and the housing 1.

[0057] The drop fit structure includes the outer edge of the housing 1 and the outer edge of the grille 2, and the outer edges of the housing 1 and the grille 2 are in different planes. This drop fit structure forms a staggered structural form, providing a certain amount of fault tolerance. When the grille 2 is assembled with the housing 1, even if the grille 2 is not fully installed and tilts to a certain extent, the edge where the housing 1 and the grille 2 fit is always the outer edge of the housing 1 or the outer edge of the grille 2, and the outer edge of the housing 1 and the outer edge of the grille 2 can ensure flatness during processing, so there will be no obvious unevenness at the fitting edge position of the grille 2 and the housing 1, thereby improving the appearance of the whole machine and enhancing the user experience.

[0058] Furthermore, the inclined matching structure extends obliquely from the inner end 302 to the outer end 301 in a direction away from the center line of the housing 1 .

[0059] In this embodiment, the inclined matching structure is arranged from the inner end 302 to the outer end 301 away from the center line of the housing 1 (the center line of the housing 1 is as shown in FIG. Figure 1 The cross section of the inclined matching structure along the thickness direction of the housing 1 can be a plane, an arc surface, a curved surface, etc., as long as its structural form does not affect the assembly of the grille 2 and the housing 1.

[0060] The center line of the housing 1 refers to a straight line passing through the center points of the upper and lower surfaces of the housing 1 and perpendicular to the upper and lower surfaces of the housing 1 .

[0061] In other embodiments, the inclined matching structure may also be a non-smooth continuous structure, such as a stepped structure, as long as the outer end 301 of the inclined matching structure is closer to the outer wall of the housing 1 than the inner end 302 so that the grille 2 can be installed smoothly.

[0062] Furthermore, the inclined matching structure includes a first inclined surface 303 and a second inclined surface 304 which are arranged in a close relationship. The first inclined surface 303 is arranged on the inner wall of the housing 1 , and the second inclined surface 304 is arranged on the outer wall of the grille 2 .

[0063] In this embodiment, the cross-section of the inclined matching structure along the thickness direction of the shell 1 is a planar structure, and the inclined matching structure includes a first inclined surface 303 and a second inclined surface 304. The first inclined surface 303 is arranged on the inner wall of the shell 1, and the second inclined surface 304 is arranged on the outer wall of the grille 2. The first inclined surface 303 and the second inclined surface 304 can be arranged in a fit to realize the assembly of the shell 1 and the grille 2, so that there is no obvious gap between the shell 1 and the grille 2.

[0064] Through this inclined matching structure, even if there is a certain dimensional tolerance between the outer wall of the grille 2 and the inner wall of the outer shell 1, for example, the outer dimension of the grille 2 is slightly smaller than the inner wall dimension of the outer shell 1, but because the outer wall of the grille 2 and the inner wall of the outer shell 1 are matched with the inclined surface, the outer wall of the grille 2 can fit the inner wall of the outer shell 1, thereby eliminating the gap between the two matching positions.

[0065] Of course, the extension size (from inside to outside) of the first inclined surface 303 and the second inclined surface 304 should be selected and set according to the size space of the air supply device. In principle, the larger the extension size of the first inclined surface 303 and the second inclined surface 304, the better the tolerance to dimensional tolerance.

[0066] Furthermore, the cross sections of the first inclined surface 303 and the second inclined surface 304 along the thickness direction of the housing 1 are both planes, and the inclination angle α of the first inclined surface 303 and the second inclined surface 304 relative to the thickness direction of the housing 1 is in the range of 5°-15°.

[0067] The cross sections of the first inclined surface 303 and the second inclined surface 304 along the thickness direction of the housing 1 are both planes. This kind of inclined matching structure is relatively simple and easy to manufacture. Figure 2 As shown, the inclination angle α of the first inclined surface 303 and the second inclined surface 304 relative to the thickness direction of the shell 1 ranges from 5° to 15°. Within this angle range, the obvious gap between the shell 1 and the grille 2 can be effectively eliminated, and it is beneficial to the installation of the grille 2 and the shell 1 to simplify the installation process.

[0068] For example, the inclination angle α of the first inclined surface 303 and the second inclined surface 304 relative to the thickness direction of the housing 1 may be 5°, 8°, 12°, 15°, etc.

[0069] Furthermore, the outer edge of the housing 1 is placed outside the outer edge of the grille 2 .

[0070] by Figure 2 Taking the viewing angle as an example, the outer edge of the shell 1 is arranged higher than the outer edge of the grille 2, and the outer edge of the shell 1 is higher than the outer edge of the grille 2, that is, the outer edge of the shell 1 is placed outside the outer edge of the grille 2, thereby forming a step structure.

[0071] In this step-matching structure, the outer edge of the grille 2 is placed inside the outer edge of the shell 1. Even if the grille 2 is not fully assembled and tilts to a certain extent, the end face edge of the air supply device head is the outer edge of the shell 1, thus not affecting the appearance of the entire machine.

[0072] In other embodiments, the outer edge of the shell 1 may be placed on the inner side of the outer edge of the grille 2, that is, the outer edge of the grille 2 protrudes from the outer edge of the shell 1. Even if the grille 2 is not fully assembled and tilts to a certain extent, since the outer edge of the grille 2 as a whole protrudes from the outer edge of the shell 1, from the appearance, the end face edge of the head of the air supply device is the outer edge of the grille 2, which does not affect the flatness and the appearance of the entire machine.

[0073] Furthermore, a distance L between an outer edge of the housing 1 and an outer edge of the grille 2 is less than or equal to 1 mm.

[0074] The distance between the outer edge of the housing 1 and the outer edge of the grille 2 should not be too large, otherwise the size of the head will be significantly increased, affecting the appearance of the whole machine. In this embodiment, the distance L between the outer edge of the housing 1 and the outer edge of the grille 2 is less than or equal to 1 mm, for example, the distance L can be 1 mm, 0.8 mm, 0.6 mm, 0.3 mm, etc.

[0075] Furthermore, the installation structure also includes a connection mechanism, and the housing 1 and the grille 2 are detachably connected through the connection mechanism. The housing 1 and the grille 2 are detachably connected through the connection mechanism to facilitate the removal and installation of the grille 2, facilitate daily cleaning and replacement by users, eliminate safety hazards during use, and ensure the service life of the product.

[0076] Furthermore, the connecting mechanism includes a first snap-fitting mechanism, which includes a first snap-fitting mechanism 4, a first snap-fitting slot and a disassembly hole 5. The first snap-fitting mechanism 4 and the first snap-fitting slot are snap-fitted together. The first snap-fitting mechanism 4 is arranged on one of the outer shell 1 and the grille 2, and the first snap-fitting slot is arranged on the other one. The outer wall of the outer shell 1 or the grille 2 provided with the first snap-fitting slot is provided with a disassembly hole 5, and the disassembly hole 5 connects the first snap-fitting slot and the outside.

[0077] like Figure 3 As shown, in this embodiment, the first buckle 4 is provided on the grille 2, and the first slot is provided on the housing 1. Specifically, the first buckle 4 is provided on the side of the grille 2 facing the inside of the housing 1, and the first slot is provided on the inner wall of the housing 1, and the first buckle 4 and the first slot can be snap-fitted. Specifically, one first buckle 4 is provided, and the first buckle 4 is provided on one of the long sides of the grille 2 for easy structural setting, and the setting position of the first slot corresponds to the setting position of the first buckle 4 for easy snap-fitting of the two.

[0078] The outer wall of the housing 1 or the grille 2 provided with the first card slot is provided with a disassembly hole 5. In this embodiment, the housing 1 is provided with the disassembly hole 5. Specifically, the housing 1 has a bottom 101, and the opening of the disassembly hole 5 is located at the bottom 101, so that the disassembly hole 5 is located at an inconspicuous position of the housing 1 to avoid affecting the overall appearance. The disassembly hole 5 communicates with the first card slot and the outside, so that the user can use the disassembly tool 7 to penetrate into the first card slot through the opening of the disassembly hole 5 to disassemble the first buckle 4, thereby realizing rapid and non-destructive disassembly of the grille 2 and the housing 1.

[0079] In order to avoid structural interference between the connection mechanism and the inclined matching structure and the drop matching structure, the first buckle 4 is arranged closer to the center line of the grille 2 than the inclined matching structure.

[0080] In other embodiments, the first buckle 4 can also be set on the shell 1, and the first slot is set on the grille 2. In this case, after the shell 1 and the grille 2 are assembled, the grille 2 is located on the outside and the disassembly hole 5 is set on the grille 2.

[0081] Furthermore, the first buckle 4 has an extension portion 401 , and after the first buckle 4 is matched with the first slot, the extension portion 401 is arranged close to the disassembly hole 5 .

[0082] like Figure 4 From the perspective shown, the first buckle 4 has an extension portion 401, which is located at the upper part of the first buckle 4, so that the user can operate it through the disassembly tool 7. After the first buckle 4 is engaged with the first slot, the extension portion 401 is close to and disposed toward the disassembly hole 5. After the disassembly tool 7 is inserted from the opening of the disassembly hole 5, the end of the disassembly tool 7 can abut against the extension portion 401, so that the first buckle 4 is disengaged from the first slot, and the grille 2 and the housing 1 are disassembled.

[0083] Furthermore, the connection mechanism also includes a second clamping mechanism, and the second clamping mechanism is arranged near the corner position of the housing 1 and the grille 2.

[0084] In addition to the first clamping mechanism, the connection mechanism also includes a second clamping mechanism to enhance the connection force between the housing 1 and the grille 2 and improve the structural reliability. In addition, due to the problem of uneven force, the corners of the housing 1 and the grille 2 are prone to warping and deformation after assembly. The second clamping mechanism is arranged close to the corners of the housing 1 and the grille 2 to ensure that the corners are flat, further improve the flatness of the entire grille 2 after assembly and the matching edges of the housing 1 and the grille 2, and improve the appearance of the whole machine.

[0085] In this embodiment, the housing 1 is a rectangular parallelepiped structure with four corners, and the four corners are all rounded. Accordingly, the grille 2 also has four corners, and the second snap-fitting structures are arranged near the four corners.

[0086] Furthermore, the second snap-fitting mechanism comprises a second snap-fitting buckle 6 and a second snap-fitting slot, wherein the second snap-fitting buckle 6 is arranged on one of the housing 1 and the grille 2, and the second snap-fitting slot is arranged on the other one.

[0087] In this embodiment, the second buckle 6 is provided on the grille 2, and the second slot is provided on the housing 1. Specifically, the second buckle 6 is provided on the side of the grille 2 facing the inside of the housing 1, and the second slot is provided on the inner wall of the housing 1, and the second buckle 6 and the second slot can be engaged and matched. The number of second buckles 6 is not limited. In this embodiment, multiple second buckles 6 are provided, and multiple second buckles 6 are arranged at intervals. Specifically, the distance between the middle position of the second buckle 6 and the corner position of the grille 2 is less than or equal to 20 mm.

[0088] Furthermore, on the grille 2 , the number of the second buckles 6 near each corner position may be different, such as one or two second buckles 6 may be provided.

[0089] Furthermore, the number of second buckles 6 is less than or equal to the number of second card slots.

[0090] In this embodiment, there is no limit on the number of second clips 6 and second slots, but the number of second clips 6 can be less than or equal to the number of second slots, so as to improve the flexibility of the installation structure assembly, expand the application scope of the installation structure, and meet different assembly needs.

[0091] This embodiment also provides an air supply device, including a housing 1, a grille 2 and the above-mentioned mounting structure, wherein the housing 1 and the grille 2 are assembled through the mounting structure.

[0092] In this air supply device, the shell 1 and the grille 2 are assembled through the mounting structure of this embodiment, which can eliminate the obvious gap between the shell 1 and the grille 2 and improve the flatness of the joint between the shell 1 and the grille 2, thereby improving the appearance of the air supply device.

[0093] The air supply device has a head, which includes a shell 1 and a grille 2. The grille 2 and the shell 1 are assembled to form an internal accommodation space. The fan blades, motor and other components of the air supply device are arranged in the accommodation space. Figure 1 One end of the housing 1 is an open end, and the grille 2 is assembled at the open end. The grille 2 is located on the air outlet side of the housing 1, and the grille 2 is assembled with the housing 1 through a mounting structure. Of course, the air supply device also has other structures and components that all existing air supply devices have, which will not be described in detail.

[0094] It should be noted that the middle part of the grille 2 is designed as a convex arc structure to enhance the design sense and optimize the product appearance. The flatness of the matching part of the shell 1 and the grille 2 referred to in this embodiment is the flatness of the matching part of the outer edge of the shell 1 and the outer edge of the grille 2, that is, the degree of flushness of the outer edge of the shell 1 and the outer edge of the grille 2.
