Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and more particularly, to a middle frame installation structure and an air conditioner. Background Art

[0002] The use of air conditioners has become increasingly widespread. The middle frame of an air conditioner is an important component that plays a supporting role.

[0003] In the disassembly and assembly of the middle frame of traditional air conditioners, the disassembly and assembly positions are generally at the upper air inlet grille of the air conditioner, which requires a relatively high height and good vision, making it inconvenient to apply force; simply adding a handle can easily affect the normal operation of the air outlet.

[0004] In addition, the installation structure between the middle frame and the base is a dead buckle, that is, a pin structure is used. When disassembling and assembling, the middle frame needs to be lifted along the wall surface first and then pulled horizontally with force to be removed, resulting in very difficult disassembly and assembly of the middle frame and extremely poor experience. When the air conditioner is used for a long time, the middle frame is prone to deformation, and at this time, the middle frame is easy to fall off. Summary of the Invention

[0005] To solve the above problems, according to the first aspect of the present invention, a middle frame installation structure is provided, including: a middle frame and a substrate that are detachably installed with each other. The substrate is located behind the middle frame. The middle frame includes a front side surface, and a middle frame handle is provided on the front side surface. The middle frame handle is arranged in the middle of the front air inlet unit of the middle frame. By applying force to the middle frame handle, the middle frame can be separated from the substrate.

[0006] Further, the middle frame handle extends downward along the curvature of the front side surface.

[0007] Further, a front filter is provided between the middle frame handle and the front side surface.

[0008] Further, the middle frame handle is trapezoidal with a width of 8 - 12 cm.

[0009] Further, the middle frame handle has a wavy hand - holding part.

[0010] Further, the number of middle frame handles is two, which are symmetrically arranged with respect to the central axis plane of the upper air inlet grille of the middle frame, and the distance between the two middle frame handles is the distance between the two arms of a human body.

[0011] Further, disassembly and assembly marks are provided on the middle frame handle.

[0012] Further, tongue structures are provided on the middle frame and the substrate. The tongue structure includes a buckle with an inclined surface provided on one of the middle frame and the substrate, and a tongue guide hole provided on the other of the two; the tongue guide hole can be separated from and installed on the buckle along the inclined surface.

[0013] Furthermore, a first front inclined surface and a first rear inclined surface are respectively provided on the front side and the rear side of the top of the buckle; during disassembly, the tongue guide hole moves forward along the first rear inclined surface until it disengages from the buckle; during installation, the tongue guide hole moves backward along the first front inclined surface to insert the buckle into the tongue guide hole.

[0014] Furthermore, the inclination angle of the first rear inclined surface is greater than that of the first front inclined surface.

[0015] Furthermore, the buckle is fixed to the upper edge of the substrate through a fixing arm provided at the bottom, and the tongue guide hole is provided at the upper edge of the middle frame; the buckle is inserted upward into the tongue guide hole to achieve their installation.

[0016] Furthermore, a snap structure is provided on the middle frame and the substrate, the snap structure includes a snap with a chamfered portion provided on one of the middle frame and the substrate, and a snap mounting groove with a protrusion portion provided on the other of them; the chamfered portion of the snap enters the snap mounting groove and is elastically deformed to engage and disengage with the protrusion portion of the snap mounting groove.

[0017] Furthermore, the middle frame includes an upper side surface, a filter screen guide rail is provided along the width direction of the upper side surface, and the snap or the snap mounting groove is provided near the end of the filter screen guide rail.

[0018] Furthermore, the chamfered portion includes a second front inclined surface and a second rear inclined surface; the protrusion portion includes a third front inclined surface and a third rear inclined surface; during engagement, the second rear inclined surface is guided into the snap mounting groove along the third rear inclined surface and contacts the third front inclined surface to generate an elastic force to fix the snap in the snap mounting groove; during disassembly, when the pulling force is greater than the elastic force, the snap disengages from the snap mounting groove.

[0019] Furthermore, the inclination angle of the second rear inclined surface is greater than that of the third front inclined surface, so that there is a gap between the chamfered portion and the protrusion portion.

[0020] Furthermore, the snap is fixed to the upper edge of the substrate and is located near the end of the filter screen guide rail; the snap mounting groove is provided on the upper edge of the middle frame and has an opening facing the rear side; the snap is inserted forward into the snap mounting groove to achieve their installation.

[0021] An air conditioner has a middle frame mounting structure, and the middle frame mounting structure is as described above.

[0022] The beneficial effects of the present invention at least include:

[0023] (1) The middle frame installation structure of the present invention uses a middle frame handle, making the force-bearing position for disassembly and assembly of the middle frame visually intuitive, easy to operate, and simple and labor-saving for disassembly and assembly, thereby making disassembly and assembly simple and convenient.

[0024] (2) The tongue structure adopted by the present invention is a snap fastener, and its insertion buckle is provided with an inclined surface, making the disassembly and assembly process more labor-saving and easier to guide, improving the disassembly and assembly experience.

[0025] (3) The spring buckle structure adopted by the present invention is a snap fastener, which can prevent the middle frame from falling off due to deformation through elasticity. While the assembly effect is comparable to that of traditional air conditioners, the disassembly and assembly experience is significantly better than that of traditional air conditioners.

Detailed Description of the Invention

[0036] To make the above-mentioned objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention is provided in conjunction with the drawings.

[0037] See the appendix Figures 1-7 , which is the middle frame installation structure of the present invention, including: a middle frame 4 and a substrate 5 that are detachably connected to each other. The substrate 5 is located at the rear side of the middle frame 4. The middle frame 4 includes a front side surface, and a middle frame handle 1 is provided on the front side surface. The middle frame handle 1 is arranged in the middle of the front air intake unit of the middle frame 4, which can make room for the filter guide rails on both the left and right sides and facilitate mold release during manufacturing. By applying force to the middle frame handle 1, the middle frame 4 can be separated from the substrate 5.

[0038] See the appendix Figure 1 , the middle frame handle 1 extends downward along the arc of the front side surface; the arc is consistent with the support rod of the middle frame 4; this enables the middle frame handle 1 to support the air conditioner, while also allowing the middle frame handle 1 to be easily accessible and enabling the air intake unit to operate normally.

[0039] See the appendix Figure 1 and the appendix Figure 4 , a front filter 6 is provided at the rear side of the middle frame handle 1, so that the middle frame handle 1 can prevent the front filter 6 from deforming and bulging.

[0040] See the appendix Figure 1 , the middle frame handle 1 is trapezoidal, and its width is the width of the human palm, which is 8 - 12 cm.

[0041] See the appendix Figure 1 , the hand - held part of the middle frame handle 1 is wavy, making it more suitable for hand - held force when disassembling and assembling the middle frame 4.

[0042] See the appendix Figure 1 , there are two middle frame handles 1, which are symmetrically arranged with respect to the central axis plane of the air inlet grille at the upper part of the middle frame 4; the distance between the two middle frame handles 1 is the distance between the two arms of the human body; the width and distance of the middle frame handles 1 conform to human mechanics, making it easier to apply force during disassembly and assembly.

[0043] See the appendix Figure 1 , a disassembly and assembly mark is provided on the middle frame handle 1, which makes the middle frame handle 1 easier to identify when the user opens the air - conditioner panel, thus effectively guiding disassembly and assembly.

[0044] See the appendix Figures 5-6 , the tongue structure includes a buckle 21 with an inclined surface provided on one of the middle frame 4 and the substrate 5, and a tongue guide hole 22 provided on the other; the tongue guide hole 22 can be disengaged from and installed on the buckle 21 along the inclined surface; during disassembly, the buckle 21 can be easily led out of the tongue guide hole 22, thereby improving the disassembly and assembly experience.

[0045] See the appendix Figures 5-6, on the front side and the rear side of the top of the buckle 21, there are respectively a first front inclined surface 211 and a first rear inclined surface 212; during disassembly, under the action of the horizontal component force, the middle frame 4 continuously moves upward, and the tongue guiding hole 22 moves forward along the first rear inclined surface 212 of the buckle 21 until it disengages from the buckle 21, making the entire disassembly process simple and labor-saving; during installation, the tongue guiding hole 22 moves backward along the first front inclined surface (211), enabling the buckle 21 to be inserted into the tongue guiding hole 22, making the positioning of the buckle 21 and the tongue guiding hole 22 more convenient and accurate.

[0046] See appendix Figures 5-6 , the inclination angle of the first rear inclined surface 212 at the top of the buckle 21 is greater than that of the first front inclined surface 211. During installation, it makes it easier for the buckle 21 to position the tongue guiding hole 22 and insert into it.

[0047] Preferably, the inclination angle of the first rear inclined surface is 70°.

[0048] See appendix Figure 2 and appendix Figures 5-6 , the buckle 21 is fixed to the upper edge of the substrate 5 through a fixed arm 213 provided at the bottom, and the tongue guiding hole 22 is provided at the upper edge of the middle frame 4; the buckle 21 is inserted upward into the tongue guiding hole 22 to achieve their installation; it makes it easier to cooperate between the buckle 21 and the tongue guiding hole 22, and the disassembly and assembly are more convenient.

[0049] See appendix Figures 7-8 , a snap structure includes a snap 31 with a chamfered portion 311 provided on one of the middle frame 4 and the substrate 5, and a snap mounting groove 32 with a protrusion 321 provided on the other; the chamfered portion 311 of the snap 31 enters the snap mounting groove 32 and engages and disengages with the protrusion 321 of the snap mounting groove 32 through elastic deformation. When the middle frame is deformed after long-term use, the elastic force between the snap 31 and the snap mounting groove 32 can effectively prevent the middle frame 4 from falling off.

[0050] See appendix Figures 5-6 , the middle frame 4 includes an upper side surface, and a filter screen guide rail 7 is provided along the width direction of the upper side surface. The snap 31 or the snap mounting groove 32 is provided near the end of the filter screen guide rail 7.

[0051] See appendix Figures 5-6, the chamfered portion 311 includes a second front inclined surface 3111 and a second rear inclined surface 3112; an upward protrusion 321 is provided on the lower contact surface within the snap fastener installation groove 32, and the protrusion 321 includes a third front inclined surface 3211 and a third rear inclined surface 3212; when fastening, the second rear inclined surface 3112 of the chamfered portion 311 is introduced into the snap fastener installation groove 32 along the third rear inclined surface 3212 and contacts the third front inclined surface 3211 of the protrusion 321 to generate an elastic force, fixing the snap fastener 31. When disassembling, when the pulling force is greater than the elastic force, the snap fastener 31 disengages, and the third rear inclined surface 3212 of the protrusion 321 reduces the disengagement resistance; thus, while the assembly effect is comparable to that of a traditional air conditioner, the disassembly and assembly experience is significantly better than that of a traditional air conditioner.

[0052] See Appendix Figures 7-8 , the inclination angle of the second rear inclined surface 3122 is greater than that of the third front inclined surface 3211, leaving a gap between the chamfered portion 311 and the protrusion 321, making the disassembly and assembly process more labor-saving.

[0053] Preferably, the inclination angle of the second rear inclined surface 3122 is 52°, and the inclination angle of the third front inclined surface 3211 is 42°.

[0054] See Appendix Figure 3 and Appendix Figures 7-8 , the snap fastener 31 is fixed at a position on the upper edge of the substrate 5 corresponding to the filter guide rail 7, and the snap fastener installation groove 32 is provided at the edge of the middle frame 4, with its opening direction facing the rear side; the snap fastener 31 is inserted forward into the snap fastener installation groove 32 to achieve their installation. This makes it easier to cooperate during installation and more labor-saving during disassembly.

[0055] It should be noted that in the present invention, the direction of the air outlet of the air conditioner is defined as "front".

[0056] On the other hand, the present invention provides an air conditioner (as Figures 1-4 shown), having a middle frame 4 and a substrate 5, and the middle frame 4 and the substrate 5 are installed through an air conditioner middle frame installation structure.

[0057] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be subject to the scope defined by the claims.
