Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more specifically, to an air conditioner. Background Technology

[0002] The existing air conditioner base and middle frame are connected by a snap-fit ​​structure, and the middle frame and panel are also connected by a snap-fit ​​structure. This results in a large number of snap-fit ​​structures in the air conditioner, which makes the mold design of the air conditioner difficult and costly, and also makes the assembly and disassembly of the air conditioner troublesome. Summary of the Invention

[0003] The problem addressed by this invention is how to better achieve detachable assembly of the middle frame, base, and panel, so as to reduce costs and facilitate disassembly and assembly.

[0004] To address the aforementioned issues, this invention provides an air conditioner that reduces the number of clips and enables better assembly of the air conditioner base, frame, and panel, thereby reducing costs and improving the user experience.

[0005] The present invention provides an air conditioner including a base, a middle frame and a panel. The base is provided with an assembly part, the middle frame is provided with a first connecting part, and the panel is provided with a second connecting part. The first connecting part and the second connecting part cooperate and are both connected to the assembly part to install the middle frame on the base and the panel on the middle frame.

[0006] This application, through the above-described embodiment, sets up a connection structure between the base, middle frame, and panel, allowing both the panel and middle frame to be connected to the base. This reduces or even eliminates the connection structure between the middle frame and the panel, thereby reducing the manufacturing cost of the middle frame. Furthermore, the first connecting part on the middle frame and the second connecting part on the panel are fitted together in an assembly section. This assembly section allows for simultaneous connection of the middle frame and the panel, reducing the need for assembly structures on the base and thus lowering the base's cost. Secondly, since the first and second connecting parts are fitted together in the assembly section, assembly and disassembly are also more convenient.

[0007] In an optional embodiment, the assembly part is a mounting slot provided on the base, and the first connecting part and the second connecting part cooperate to form a snap-fit ​​structure that can be snapped into the mounting slot.

[0008] This application sets the assembly part as a mounting slot, which has a simple structure and can easily realize the snap-fit ​​connection between the first connecting structure and the second connecting part.

[0009] In an optional embodiment, the second connecting part is a limiting snap-fit ​​structure protruding from the panel;

[0010] The second connecting part is a buckle disposed on the middle frame;

[0011] The buckle is installed in the mounting slot;

[0012] When the panel is in the closed state, the limiting snap-fit ​​structure is inserted into the mounting slot, so that both the buckle and the limiting snap-fit ​​structure are engaged with the mounting slot.

[0013] When the panel is in the open state, the limiting snap-fit ​​structure moves out of the mounting slot, which can make way for the buckle to create a release space, so that the buckle can disengage from the mounting slot.

[0014] This application utilizes a limiting snap-fit ​​structure on the panel. The snap-fit ​​is installed within a mounting slot, and the snap-fit ​​is engaged by inserting the limiting snap-fit ​​structure into the mounting slot. Furthermore, the snap-fit ​​and the limiting snap-fit ​​structure work together to engage the limiting snap-fit ​​structure within the mounting slot. When removing the mid-frame, the panel is opened, allowing the limiting snap-fit ​​structure to move out of the mounting slot, creating space for the snap-fit ​​to exit. This facilitates easy removal of the snap-fit ​​from the mounting slot, enabling convenient engagement and disassembly of the mid-frame and panel without requiring excessive deformation of the snap-fit, thus making the disassembly and installation of the mid-frame more convenient.

[0015] In an optional embodiment, the middle frame is provided with a clearance groove, and the limiting snap-fit ​​structure protrudes from the inner side of the panel, the limiting snap-fit ​​structure extending into the middle frame through the clearance groove.

[0016] This application provides a clearance groove on the middle frame, which allows the limiting snap-fit ​​structure to be inserted into the inside of the middle frame and can be inserted into the mounting slot when the panel is closed.

[0017] In an optional embodiment, the limiting snap-fit ​​structure gradually thins towards the end.

[0018] During the assembly process of the air conditioner, the middle frame is first assembled onto the base. At this time, the buckle will first extend into the mounting slot, and then the panel is assembled. Only after the panel can it extend into the mounting slot. The limiting snap-fit ​​structure is set to gradually thin towards the end, so that the limiting snap-fit ​​structure forms a wedge shape, which is convenient to insert into the mounting slot and can form a snap-fit ​​with the buckle and the side wall of the slot.

[0019] In an optional embodiment, the mounting slot has opposing first and second sidewalls;

[0020] The first sidewall is provided with a recessed snap-fit ​​groove;

[0021] The buckle has a protruding part that mates with the snap-fit ​​groove, protruding towards the first side wall;

[0022] When the panel is in the closed state, the limiting snap-fit ​​structure can be inserted between the buckle and the second side wall so that the snap protrusion engages with the snap-fit ​​groove;

[0023] When the panel is in the open state, the limiting latching structure can be moved out from between the latch and the second side wall to make way for the latch protrusion.

[0024] This application provides a snap-fit ​​groove on the first side wall of the mounting slot, and a snap-fit ​​protrusion on the buckle. When the buckle is inserted into the mounting slot, the limiting snap-fit ​​structure can be inserted between the second side wall and the buckle. A force is applied to the buckle from behind, thus confining the snap-fit ​​protrusion within the snap-fit ​​groove. The limiting snap-fit ​​structure is engaged between the buckle and the second side wall through an interference fit.

[0025] In an optional embodiment, the opening size of the mounting slot is larger than the size of the protrusion; and / or,

[0026] The opening of the mounting slot is smaller than the sum of the thicknesses of the buckle and the limiting snap-fit ​​structure, so that when the limiting snap-fit ​​structure is engaged with the buckle, the limiting snap-fit ​​structure can snap into the opening.

[0027] The size of the mounting slot opening is larger than the size of the protruding part of the buckle. This allows the protruding part of the buckle to better enter and exit the locking slot, making installation and disassembly easier. The size of the mounting slot opening is smaller than the sum of the thicknesses of the buckle and the limiting locking structure. When the limiting locking structure and the buckle are engaged, the limiting locking structure can lock into the opening, thus achieving an interference fit.

[0028] In an optional embodiment, the snap-fit ​​groove is an arc groove, and the snap-fit ​​protrusion has a mating surface that engages with the arc groove. When the snap-fit ​​protrusion engages with the snap-fit ​​groove, the arc groove engages with the mating surface.

[0029] The circular arc contact increases the stress-bearing area and also has a guiding function. It can guide the movement of the middle frame when it is removed.

[0030] In an optional embodiment, the latch protrusion is provided with a first guide surface. The first guide surface on the latch protrusion allows for guidance during the installation of the middle frame.

[0031] In an optional embodiment, the first sidewall is provided with a second guide surface. The second guide surface on the second sidewall serves as a guide during the installation of the middle frame.

[0032] In an optional embodiment, the second sidewall is provided with a third guide surface. Providing a third guide surface on the second sidewall allows for guidance during the insertion of the locking and retaining structure.

[0033] In an optional embodiment, both the buckle and the limiting engagement structure are provided with grooves, which allow ribs to be formed on the buckle and the limiting engagement structure. This groove-forming process helps to prevent noise by creating a thinner adhesive layer. Attached Figure Description

Detailed Implementation

[0044] The existing air conditioner base and middle frame are connected by a snap-fit ​​structure, and the middle frame and panel are also connected by a snap-fit ​​structure. This results in a large number of snap-fit ​​structures in the air conditioner, which makes the mold design of the air conditioner difficult and costly, and also makes the assembly and disassembly of the air conditioner troublesome.

[0045] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0046] It should be noted that the descriptions of horizontal, vertical, and other directions in the embodiments refer to the position of the indoor unit 100 in its installed state, i.e. Figure 1 The state in.

[0047] Please refer to Figure 1 and Figure 2 This embodiment provides an air conditioner 300, which generally includes an indoor unit 100 and an outdoor unit. The indoor unit 100 and the outdoor unit are connected by a heat exchange pipe to achieve refrigerant circulation. The indoor unit 100 includes a base 110, a middle frame 130, and a panel 150. The base 110 is provided with an assembly part 101, the middle frame 130 is provided with a first connecting part 102, and the panel 150 is provided with a second connecting part 103. The first connecting part 102 and the second connecting part 103 cooperate with the third connecting part and are all connected to the assembly part 101 to install the middle frame 130 onto the base 110 and the panel 150 onto the middle frame 130.

[0048] This application, through the above-described embodiment, sets up a connection structure between the base 110, the middle frame 130, and the panel 150, allowing both the panel 150 and the middle frame 130 to be connected to the base 110. This reduces or even eliminates the connection structure between the middle frame 130 and the panel 150, thereby reducing the manufacturing cost of the middle frame 130. Furthermore, the first connecting portion 102 on the middle frame 130 and the second connecting portion 103 on the panel 150 are connected in assembly section 101. This assembly section 101 allows for simultaneous connection of the middle frame 130 and the panel 150, reducing the need for assembly structures on the base 110 and thus lowering its cost. Additionally, the assembly of the first connecting portion 102 and the second connecting portion 103 within the assembly section 101 facilitates assembly and disassembly.

[0049] It should be noted that the base 110 serves as the carrier for mounting components such as the heat exchanger and fan on the indoor unit 100. The middle frame 130 is mounted on the base 110 to form a chamber, thereby enclosing the heat exchanger, fan, etc., within the chamber. Generally, the middle frame 130 and the base 110 are detachably connected for ease of cleaning and maintenance. The panel 150 is mounted on the front of the middle frame 130 and can be removed for cleaning components such as the filter.

[0050] In this embodiment, the assembly part 101 is a mounting slot 111 provided on the base 110, and the first connecting part 102 and the second connecting part 103 cooperate to form a snap-fit ​​structure that can be snapped into the mounting slot.

[0051] In this embodiment, by setting the assembly part 101 as the mounting slot 111, the structure is simple and can easily realize the snap-fit ​​connection between the first connecting structure and the second connecting part.

[0052] In this embodiment, the second connecting part is a limiting snap-fit ​​structure 151 protruding from the panel 150. The second connecting part is a buckle 131 disposed on the middle frame 130. The buckle 131 is installed in the mounting slot 111. When the panel 150 is in the closed state, the limiting snap-fit ​​structure 151 is inserted into the mounting slot 111, so that both the buckle 131 and the limiting snap-fit ​​structure 151 are engaged with the mounting slot 111. When the panel 150 is in the open state, the limiting snap-fit ​​structure 151 moves out of the mounting slot 111, which makes room for the buckle 131 to form an exit space 140, so that the buckle 131 can disengage from the mounting slot 111.

[0053] Please refer to Figures 1 to 6 In this embodiment, a limiting snap-fit ​​structure 151 is provided on the panel 150, and the buckle 131 is installed in the mounting slot 111. The buckle 131 is snapped into the mounting slot 111 by inserting the limiting snap-fit ​​structure 151 on the panel 150. When removing the middle frame 130, the panel 150 is opened, allowing the limiting snap-fit ​​structure 151 to move out of the mounting slot 111, creating a release space 140 for the buckle 131. This facilitates the removal of the buckle 131 from the mounting slot 111, eliminating the need for excessive deformation of the buckle 131 and making the connection and removal of the middle frame 130 and the panel 150 more convenient. It also prevents damage to the buckle 131 during disassembly.

[0054] Please refer to Figure 2 , Figure 4 and Figure 6 In this embodiment, the middle frame 130 is provided with a relief groove 133, and the limiting snap-fit ​​structure 151 protrudes from the inner side of the panel 150. The limiting snap-fit ​​structure 151 extends into the middle frame 130 through the relief groove 133.

[0055] In this embodiment, by providing a clearance groove 133 on the middle frame 130, the limiting snap-fit ​​structure 151 can be inserted into the interior of the middle frame 130 and can be inserted into the mounting slot 111 when the panel 150 is closed. The clearance groove 133 can also position the limiting snap-fit ​​structure 151, so that the limiting snap-fit ​​structure 151 can be better inserted into the mounting slot 111 when the panel 150 is assembled.

[0056] In this embodiment, the limiting snap-fit ​​structure 151 gradually thins towards the end.

[0057] During the assembly process of the air conditioner 300, the middle frame 130 is first assembled onto the base 110. At this time, the buckle 131 will first extend into the mounting slot 111, and then the panel 150 is assembled. Only after the panel 150 can it extend into the mounting slot 111. The limiting snap-fit ​​structure 151 is set to gradually thin towards the end so that the limiting snap-fit ​​structure 151 forms a wedge shape, which is convenient to be inserted into the mounting slot 111 and can form a snap-fit ​​with the buckle 131 and the side wall of the slot.

[0058] Specifically, the limiting snap-fit ​​structure 151 is roughly triangular in shape, with one side parallel to the horizontal direction. A wedge-shaped insertion portion of a certain thickness is formed at the apex, which can be inserted into the mounting slot 111. The interior of the triangle is hollowed out to reduce weight, thereby increasing the structural mechanical strength. It also cooperates with the sidewall of the clearance groove 133, allowing the limiting snap-fit ​​structure 151 to be better inserted into the mounting slot 111 during panel 150 assembly.

[0059] Please refer to Figure 2 , Figure 4 and Figure 6 In this embodiment, the mounting slot 111 has a first sidewall 113 and a second sidewall 115. The first sidewall 113 is recessed with a snap-fit ​​groove 117. The buckle 131 protrudes towards the first sidewall 113 with a snap-fit ​​protrusion 134 that engages with the snap-fit ​​groove 117. When the panel 150 is in the closed state, the limiting snap-fit ​​structure 151 is interference-fitted between the buckle 131 and the second sidewall 115 to allow the snap-fit ​​protrusion 134 to engage with the snap-fit ​​groove 117. When the panel 150 is in the open state, the limiting snap-fit ​​structure 151 can be moved out from between the buckle 131 and the second sidewall 115 to allow the snap-fit ​​protrusion 134 to move out of the way.

[0060] In this embodiment, a snap-fit ​​groove 117 is provided on the first side wall 113 of the mounting groove 111, and a snap-fit ​​protrusion 134 is provided on the buckle 131. After the buckle 131 is inserted into the mounting groove 111, the limiting snap-fit ​​structure 151 can be inserted between the second side wall 115 and the buckle 131, thus restricting the snap-fit ​​protrusion 134 within the snap-fit ​​groove 117, thereby achieving snap-fit.

[0061] It should be noted that the first sidewall 113 and the second sidewall 115 can be understood as two opposite parts of the mounting slot 111, which can be either curved or flat.

[0062] Please refer to Figure 2 , Figure 4 and Figure 6In this embodiment, the latching protrusion 134 protrudes towards the bottom of the air conditioner 300. That is, the latching protrusion 134 protrudes towards the bottom of the indoor unit 100. In this way, when the panel 150 is opened, the latching protrusion 134 is still flexibly engaged in the latching groove 117 under the action of gravity, and will not fall off directly. Only when an external force is applied will the latching protrusion 134 detach from the latching groove 117.

[0063] Specifically, the buckle 131 can be understood as a horizontally extending fixing rib inside the middle frame 130. The latch protrusion 134 protrudes towards the bottom. The first side wall 113 is located below the mounting slot 111, and the second side wall 115 is located above the mounting slot 111. The lower limit latching structure 151 is inserted above the buckle 131.

[0064] Of course, in other embodiments of this application, the protrusion 134 may also protrude upwards, for example, when there are other connections between the middle frame 130 and the base 110.

[0065] In this embodiment, the second sidewall 115 is an arc surface and protrudes outward toward the mounting slot 111, so that a larger exit space 140 can be formed after the limiting snap-fit ​​structure 151 is moved out.

[0066] Please refer to Figure 2 , Figure 4 and Figure 6 In this embodiment, the size of the opening 119 of the mounting slot 111 is larger than the size of the protrusion 134. That is, the size of the end of the buckle 131 is smaller than the size of the opening 119 of the mounting slot 111, so that the end of the buckle 131 can be easily inserted into the mounting slot 111 during installation, and the opening 119 of the mounting slot 111 will not engage the buckle 131 during disassembly.

[0067] In this embodiment, the opening 119 of the mounting slot 111 is smaller than the sum of the thicknesses of the buckle 131 and the limiting snap-fit ​​structure 151, so that when the limiting snap-fit ​​structure 151 and the buckle 131 are engaged, the limiting snap-fit ​​structure 151 can be snapped into the opening 119. In this way, the limiting snap-fit ​​structure 151 can be interference-fitted using the second sidewall 115 and the buckle 131.

[0068] Normally, the middle frame 130 and the base 110 are equipped with mutually cooperating positioning mechanisms. During the installation of the middle frame 130, as the distance between the middle frame 130 and the base 110 decreases, the positioning mechanisms continuously reduce the range of motion of the middle frame 130 relative to the base 110, so as to achieve a preset assembly effect between the middle frame 130 and the base 110, until the two are fastened together, at which point the latching protrusion 134 will also engage in the latching groove 117. During the removal of the middle frame 130, the distance between the two increases, and the cooperating effect between the positioning mechanisms gradually weakens, thereby increasing the range of motion between the two, so that the latching protrusion 134 can be moved out of the latching groove 117.

[0069] In this embodiment, the snap-fit ​​groove 117 is an arc groove, and the snap-fit ​​protrusion 134 has a mating surface that engages with the arc groove. When the snap-fit ​​protrusion 134 engages with the snap-fit ​​groove 117, the arc groove engages with the mating surface.

[0070] In this embodiment, the arc contact can increase the force-bearing area and has a guiding function. It can guide the middle frame 130 when it is removed, so that the middle frame 130 can move relative to the base 110 or the buckle 131 can be slightly deformed to allow the buckle protrusion 134 to move out of the buckle groove 117.

[0071] Of course, in other embodiments of this application, the shape of the card protrusion 134 and the card slot 117 may also be an outer triangular cross section or be chamfered.

[0072] Please refer to Figure 2 , Figure 4 and Figure 6 In this embodiment, the protrusion 134 is provided with a first guide surface 135. The first guide surface 135 on the protrusion 134 can guide the middle frame 130 during installation so that the buckle 131 can be inserted into the mounting slot 111 through the opening 119 of the mounting slot 111.

[0073] In this embodiment, the first guide surface 135 is an inclined plane. The angle between the first guide surface 135 and the horizontal plane ranges from 45° to 60°.

[0074] Of course, in some other embodiments of this application, the first guide surface 135 may also be an arc surface.

[0075] In this embodiment, the first sidewall 113 is provided with a second guide surface 121. The second sidewall 115 is provided with a second guide surface 121 so that it can play a guiding role when installing the middle frame 130. The second sidewall 115 is provided with a third guide surface 123. The third guide surface 123 on the second sidewall 115 can guide when the limiting snap-fit ​​structure 151 is inserted.

[0076] Specifically, the second guide surface 121 and the third guide surface 123 are arranged such that the opening 119 of the mounting slot 111 is flared outwards and inwards, so that one side guides the buckle 131 and the other side guides the limiting snap-fit ​​structure 151.

[0077] Please refer to Figure 2 , Figure 4 and Figure 6 In this embodiment, both the buckle 131 and the limiting snap-fit ​​structure 151 are provided with a groove 125. The groove 125 forms a glue-skimming process, which can avoid abnormal noise.

[0078] Secondly, in this embodiment, the base 110, the middle frame 130, and the panel 150 are assembled together using multiple of the above-described structures, and the specific number is not specifically limited in this application. Furthermore, the orientation of the buckles 131 and mounting slots 111 at different positions, as well as the protrusions 134 and the grooves 117, can be adaptively adjusted to meet the assembly requirements of the middle frame 130 and the base 110.

[0079] Please refer to Figure 7 Of course, in some embodiments of this application, the first connecting part 102 and the second connecting part 103 may both be trapezoidal wedge-shaped, so as to be inserted into the assembly groove of the base 110 and achieve a fixed connection by means of interference fit.

[0080] Specifically, considering installation stability, protruding locking protrusions 134 can be provided on the first connecting part 102 and / or the second connecting part 103 to engage with the groove on the side wall of the mounting slot 111, achieving a stable connection between the three. Generally, considering the assembly process and ease of disassembly of the air conditioner, it is sufficient to provide locking protrusions 134 on the first connecting part 102 located on the middle frame 130.

[0081] Secondly, please refer to Figure 8 In some embodiments, the first connecting part 102 can be configured as a hollow connecting post, with a deformation groove at the end of the connecting post. The second connecting part 103 can also be configured as a connecting post, with a protruding snap-fit ​​portion and a deformation groove at its end. The connecting post of the middle frame 130 is inserted into the mounting slot 111 of the base 110, and the connecting post of the panel 150 is inserted through the inner ring of the connecting post of the middle frame 130. Under the action of the snap-fit ​​portion, the end of the first connecting part 102 can open and snap into the mounting slot 111, while the second connecting part 103 snaps into the inner ring of the first connecting part 102. This achieves fixation of all three components, and the snap-fit ​​between the middle frame 130 and the base 110 can be released after the panel 150 is removed, thus facilitating the disassembly and cleaning of the middle frame 130. To ensure the snap-fit ​​effect, in this embodiment, the mounting slot 111 can also be configured as a gradient slot below the opening 119.

[0082] It should also be noted that this application does not limit the mounting portion 101 provided on the mounting base 110 to a groove. In some embodiments, the mounting portion 101 may be a protruding connecting structure.

[0083] For example, please refer to Figure 9 In some embodiments, the assembly structure is a hollow snap-fit ​​post with a deformation groove at the end. The first connecting part 102 is a hollow connecting post with a limit protrusion on the inner ring of the end. The second connecting part 103 is a truncated cone. After the middle frame 130 is assembled onto the base 110, the hollow connecting post is fitted onto the snap-fit ​​post, but the two are not snapped together at this time. After the panel 150 is installed onto the middle frame 130, the truncated cone extends into the snap-fit ​​post, causing the end of the connecting post to open, thereby snapping the snap-fit ​​post into the connecting post. The truncated cone is snapped into the snap-fit ​​post, thus achieving a stable connection between the three. This also makes the installation and removal of the middle frame 130 and the panel 150 more convenient.

[0084] In summary, the working principle and beneficial effects of the air conditioner 300 provided in this embodiment include:

[0085] This application, through the above-described embodiment, sets up a connection structure between the base 110, the middle frame 130, and the panel 150, allowing both the panel 150 and the middle frame 130 to be connected to the base 110. This reduces or even eliminates the connection structure between the middle frame 130 and the panel 150, thereby reducing the manufacturing cost of the middle frame 130. Furthermore, the first connecting portion 102 on the middle frame 130 and the second connecting portion 103 on the panel 150 are connected in assembly section 101. This assembly section 101 allows for simultaneous connection of the middle frame 130 and the panel 150, reducing the need for assembly structures on the base 110 and thus lowering its cost. Additionally, the assembly of the first connecting portion 102 and the second connecting portion 103 within the assembly section 101 facilitates assembly and disassembly.

[0086] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
