Description

Technical Field

[0001] The present invention relates to the technical field of air conditioner structures, and in particular to an air conditioner middle frame, an air conditioner indoor unit and an air conditioner. Background Art

[0002] The air conditioner's midframe is a crucial support structure for the indoor unit, and features exhaust vents to dissipate air. End caps are installed at each end of the midframe to shield the ends. Currently, the midframe and end caps are typically connected using a snap-fit ​​connection, with holes at the ends of the midframe providing a secure connection for the end caps.

[0003] However, studies have found that existing air conditioner indoor units have a technical problem of poor blowing effect when in use. Summary of the Invention

[0004] The problem solved by the present invention is how to improve the technical problem of poor blowing effect of the exhaust outlet in the prior art.

[0005] In order to solve the above problems, the present invention provides an air conditioner middle frame, an air conditioner indoor unit and an air conditioner, which can effectively improve the above-mentioned technical problems.

[0006] The present invention can be implemented like this:

[0007] An embodiment of the present invention provides an air conditioner middle frame having an exhaust vent and a latch hole corresponding to the exhaust vent. The latch hole is located at an end of the air conditioner middle frame and is configured to engage with a latch on an end cover. One end of the latch hole forms a first opening for the latch to enter and exit. A partition is provided between the bottom of the latch hole and the exhaust vent of the air conditioner middle frame to prevent the latch hole from intersecting with the exhaust vent. The partition separates the latch hole from the exhaust vent of the air conditioner middle frame, thereby preventing the exhaust vent and the latch hole from intersecting with each other. The airflow at the exhaust vent is not affected by the latch hole, thereby improving the air blowing effect.

[0008] Optionally, the card hole includes a first hole segment and a second hole segment that are connected to each other, the first hole segment extends along the length direction of the air conditioner middle frame, and the first hole segment forms the first opening at one end away from the exhaust port, the other end of the first hole segment is connected to the second hole segment, the extension direction of the second hole segment is at an angle to the extension direction of the first hole segment, and a hook portion is formed at the connection between the first hole segment and the second hole segment for hooking with the buckle of the end cover; the partition portion forms the bottom of the first hole segment.

[0009] The latching hole includes a first and second interconnected hole segments. The first and second hole segments extend in a direction that is inclined relative to each other. This allows the corner formed at the junction of the first and second hole segments to function as a hooking portion for engagement with the latching hook of the end cap. The partition portion forms the bottom of the first hole segment, thereby preventing the first hole segment, which extends along the length of the air conditioner middle frame, from intersecting with the exhaust vent.

[0010] Optionally, the second hole segment extends in a vertically upward direction. Since the air outlet is located at the lower part of the air conditioner middle frame, the clamping hole opposite to the air outlet is located at the lower part of the air conditioner middle frame. There is sufficient space above the clamping hole for setting and forming the second hole segment, which is more convenient for production.

[0011] Optionally, the second hole segment forms a second opening at one end away from the first hole segment. The second opening of the second hole segment can be used for demolding of the molding mold. In this way, when the clamping hole of the air conditioner middle frame is produced by injection molding, the first hole segment and the second hole segment can be produced by two independent demolding slides. During demolding, the demolding slide for forming the first hole segment can slide out of the first opening, and the demolding slide for forming the second hole segment can slide out of the second opening. This simplifies the mold structure and facilitates production.

[0012] Optionally, a draft guide rib is provided outside the second opening, extending along the extension direction of the second hole segment and away from the second opening. The draft guide rib is provided at the second opening to guide a demolding slider forming the second hole segment, thereby ensuring a convenient and reliable demolding process.

[0013] Optionally, a draft avoidance hole is formed outside the second opening, extending in the direction of extension of the second hole segment and away from the second opening. By providing the draft avoidance hole at the second opening, the demolding slider used to form the second hole segment will not contact or rub against the side wall of the air conditioner middle frame during demolding, making demolding more convenient.

[0014] Optionally, draft guide ribs are provided on both sides of the draft avoidance hole, extending along the edge of the draft avoidance hole. Providing draft guide ribs on both sides of the draft avoidance hole allows the two draft guide ribs to guide the ejection slider during the formation of the second hole segment, thereby improving draft stability.

[0015] Optionally, the exhaust port has a sloped structure, and the bottom of the latch hole is an inclined structure extending along the side wall of the exhaust port. That is, the bottom of the latch hole is arranged substantially parallel to the side wall of the exhaust port. In this way, the thickness of the partition separating the latch hole and the exhaust port is uniform throughout, facilitating injection molding and achieving good injection molding results.

[0016] An embodiment of the present invention further provides an air conditioner indoor unit, comprising an end cover and an air conditioner middle frame. The air conditioner middle frame has an exhaust port and a latch hole corresponding to the exhaust port. The latch hole is located at an end of the air conditioner middle frame and is configured to engage with a latch on the end cover. One end of the latch hole forms a first opening for the end cover latch to enter and exit. A partition is provided between the bottom of the latch hole and the air conditioner middle frame exhaust port to prevent the latch hole from intersecting with the exhaust port. Because the air conditioner indoor unit includes the air conditioner middle frame, it also has the advantage of a good air blowing effect.

[0017] The embodiment of the present invention further provides an air conditioner, which includes the above-mentioned air conditioner indoor unit. Since the air conditioner includes the above-mentioned air conditioner indoor unit, it also has the advantage of good blowing effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] At present, both ends of the air conditioner middle frame are provided with end covers, and the end covers are provided with buckles. Correspondingly, a clamping hole is opened at the end of the air conditioner middle frame. However, research has found that in the existing air conditioner middle frame, the clamping hole is connected with the exhaust port, and part of the air flow at the exhaust port enters the clamping hole, which not only affects the end cover itself, but may also cause the end cover to shake relative to the air conditioner middle frame, and the blowing effect at the exhaust port is poor, affecting the use effect.

[0029] Figure 1 This is a structural diagram of the air conditioner middle frame 100 provided in this embodiment. Figure 2 This is a schematic cross-sectional view of the air conditioner middle frame 100 provided in this embodiment at a first viewing angle. Figure 3 for Figure 2 A magnified schematic diagram of the local structure at point III. Figure 4 This is a schematic cross-sectional view of the air conditioner middle frame 100 provided in this embodiment at a second viewing angle. Figure 5 for Figure 4 The enlarged schematic diagram of the local structure at point V in the middle, Figure 6 This is a structural diagram of the air conditioner middle frame 100 and the end cover 210 provided in this embodiment. Figures 1-6 This embodiment provides an air conditioner middle frame 100, and accordingly provides an air conditioner indoor unit and an air conditioner (not shown).

[0030] The air conditioner includes an indoor unit and an outdoor unit. The indoor unit and the outdoor unit are connected to form a heat exchange circuit for circulating heat exchange medium to achieve heat exchange between indoor and outdoor, thereby achieving the purpose of cooling or heating the room.

[0031] The air conditioner indoor unit includes an air conditioner middle frame 100 and end caps 210, which are disposed at both ends of the air conditioner middle frame 100 in the longitudinal direction. The end caps 210 are provided with buckles 211, and the ends of the air conditioner middle frame 100 are provided with locking holes 120. The buckles 211 engage with the locking holes 120 to connect the end caps 210 to the air conditioner middle frame 100.

[0032] The air conditioner middle frame 100 has an exhaust port 110 and a latch hole 120 corresponding to the position of the exhaust port 110. The latch hole 120 is located at the end of the air conditioner middle frame 100 and is used to latch with the end cover 210. One end of the latch hole 120 forms a first opening 123 for the buckle 211 of the end cover 210 to enter and exit. A partition portion 130 is provided between the bottom of the latch hole 120 and the exhaust port 110 of the air conditioner middle frame 100 to prevent the latch hole 120 from intersecting with the exhaust port 110. The partition portion 130 separates the latch hole 120 from the exhaust port 110 of the air conditioner middle frame 100, thereby preventing the exhaust port 110 from intersecting with the latch hole 120. The airflow at the exhaust port 110 is not affected by the latch hole 120, thereby improving the blowing effect.

[0033] It should be noted that, in the description of this embodiment, the "card hole 120 corresponding to the position of the air outlet 110" refers to the card hole 120 along the length direction of the air conditioner middle frame 100 ( Figure 1 In the direction A), the projection of the card hole 120 at the position of the air outlet 110 at least partially overlaps with the air outlet 110.

[0034] The air conditioner middle frame 100 provided in this embodiment is further described below:

[0035] Please continue to refer to Figures 1-6 In this embodiment, the latch hole 120 includes a first hole segment 121 and a second hole segment 122 that are interconnected. The first hole segment 121 extends along the length of the air conditioner middle frame 100. The first hole segment 121 and the exhaust port 110 are arranged along the length of the air conditioner middle frame 100 in a corresponding manner. That is, the projection of the first hole segment 121 along the length of the air conditioner middle frame 100 intersects with the exhaust port 110 or falls into the location of the exhaust port 110. The end of the first hole segment 121 away from the exhaust port 110 forms a first opening 123. That is, the end of the first hole segment 121 facing away from the exhaust port 110 is open, so that the latch 211 on the end cover 210 can extend from the first opening 123 into the first hole segment 121.

[0036] The other end of the first hole segment 121 is connected to the second hole segment 122, and the extension direction of the second hole segment 122 is at an angle to the connection direction of the first hole segment 121, thereby forming an L-shaped clamping hole structure. At the same time, the corner protrusion formed at the connection between the first hole segment 121 and the second hole segment 122 can be used as a hook portion 125 to hook with the buckle 211 of the end cover 210, thereby realizing the buckling of the end cover 210 on the end of the air conditioner middle frame 100.

[0037] The partition portion 130 forms the bottom of the first hole segment 121. In this way, along the length direction of the air conditioner middle frame 100, the first hole segment 121 is separated from the exhaust port 110 by the partition portion 130, thereby avoiding the problem of the card hole 120 and the exhaust port 110 being connected and air flow entering the card hole 120. In other words, the partition portion 130 can also be regarded as a partition structure formed at the bottom of the first hole segment 121.

[0038] It should be noted that the structure of the card hole 120 is not restricted here. It can be understood that when the partition portion 130 is set to block one end of the first hole section 121 close to the exhaust port 110, in order to ensure that the buckle 211 of the end cover 210 can be smoothly engaged with the card hole 120, in some other embodiments, a protrusion can also be set in the first hole section 121 as a hook portion 125.

[0039] Figure 7 This is a structural diagram of the mold manufacturing the card hole 120 in the air conditioner middle frame 100 provided in this embodiment. Figure 1-Figure 7 Furthermore, a second opening 124 is formed at one end of the second hole segment 122 away from the first hole segment 121, that is, the formed card hole 120 is L-shaped with both free ends open. In this way, when the card hole 120 is molded by injection molding, the first hole segment 121 and the second hole segment 122 can be respectively molded by two independent mold sliders. Specifically, the mold slider for molding the first hole segment 121 is the first mold slider 221, and the mold slider for molding the second hole segment 122 is the second mold slider 222.

[0040] The first demolding slider 221 extends along the length of the air conditioner middle frame 100, and the end of the first demolding slider 221 is spaced from the exhaust port 110, thereby forming the partition portion 130 between the first hole section 121 and the exhaust port 110. One end of the second demolding slider 222 abuts against the first demolding slider 221, so that the formed second hole section 122 communicates with the first hole section 121.

[0041] Furthermore, the second hole segment 122 extends in a vertically upward direction. Since the latch hole 120 is located at the lower end of the air conditioner middle frame 100, there is sufficient space above the first hole segment 121 for the second hole segment 122. At the same time, the exhaust port 110 has a sloped structure, that is, the exhaust port 110 is shaped so that the opening area gradually increases along the air outlet direction, and its sidewalls are arranged at an angle. In this way, arranging the second hole segment 122 above the first hole segment 121 can effectively avoid the exhaust port 110, ensure that the latch hole 120 and the exhaust port 110 are spatially independent of each other, and facilitate the injection molding of the second hole segment 122. It is understandable that in some other embodiments, the extension direction of the second hole segment 122 can also be set according to needs, for example, the second hole segment 122 is set to a structure that extends obliquely upward.

[0042] Furthermore, the bottom of the retaining hole 120 is an inclined structure extending along the sidewall of the exhaust port 110. Specifically, the bottom of the retaining hole 120 and the sidewall of the exhaust port 110 corresponding to the retaining hole 120 are arranged substantially parallel to each other. This allows the thickness of the partition portion 130 to be roughly uniform at all locations, facilitating the injection of material during injection molding and facilitating the injection molding process. Specifically, the bottom wall of the first ejection slider 221 that forms the first hole segment 121 is arranged at an angle, so that the bottom of the first hole segment 121 formed in this manner also has an inclined structure.

[0043] Please continue to refer to Figure 1-Figure 7 In this embodiment, a draft avoidance hole 141 is formed outside the second opening 124 of the second hole section 122. Thus, a platform surface is formed between the second opening 124 and the draft avoidance hole 141. The second demolding slider 222 has a step that abuts against the platform surface, thereby positioning the second demolding slider 222. Simultaneously, the second demolding slider 222 is positioned within the draft avoidance hole 141 on a side that is close to the side wall of the air conditioner middle frame 100 along the length direction of the air conditioner middle frame 100. Thus, the second demolding slider 222 does not directly contact the side wall of the air conditioner middle frame 100, thereby preventing sliding friction between the second demolding slider 222 and the side wall of the air conditioner middle frame 100 when the second demolding slider 222 is demolded, thereby facilitating demolding of the second demolding slider 222.

[0044] Meanwhile, the demoulding avoidance hole 141 is in the shape of a strip extending along the extension direction of the second hole section 122 in a direction away from the second opening 124 , thereby providing a movable space for the second demoulding slider 222 to slide out of the mold.

[0045] Furthermore, an ejection guide rib is provided outside the second opening 124, and the ejection guide rib extends along the extension direction of the second hole section 122 in a direction away from the second opening 124. In this way, when the second ejection slider 222 is ejected from the mold, the ejection guide rib can guide the ejection direction of the second ejection slider 222, which helps to reduce the difficulty of ejection and ensure the injection molding effect.

[0046] Optionally, the draft guide ribs are arranged on both sides of the draft avoidance hole 141, that is, in this embodiment, the number of the draft guide ribs is two, and the two draft guide ribs are the first draft guide rib 142 and the second draft guide rib 143. The first draft guide rib 142 and the second draft guide rib 143 extend along the edge of the draft avoidance hole 141. In this way, the first draft guide rib 142 and the second draft guide rib 143 jointly guide the demolding of the second demolding slider 222, which can effectively ensure the demolding direction stability of the second demolding slider 222.

[0047] In this embodiment, two latch holes 120 corresponding to the air outlet 110 are provided at the end of the air conditioner middle frame 100. The two latch holes 120 are arranged side by side along the front-to-back direction of the air conditioner middle frame 100, and the two latch holes 120 are both L-shaped.

[0048] In the air conditioner middle frame 100, air conditioner indoor unit, and air conditioner provided by the embodiments of the present invention, the latch hole 120 corresponding to the exhaust port 110 on the air conditioner middle frame 100 is set to be L-shaped, thereby separating the exhaust port 110 from the latch hole 120, preventing the latch hole 120 from being connected to the exhaust port 110, and thus preventing the airflow at the exhaust port 110 from entering the latch hole 120, thereby affecting the blowing effect. At the same time, by specifically setting the latch hole 120 structure and providing the draft avoidance hole 141 and the draft guide rib at the second opening 124 of the latch hole 120, the convenience and molding effect of the injection molding of the latch hole 120 are guaranteed.

[0049] In summary, the embodiments of the present invention provide an air conditioner middle frame 100 , an air conditioner indoor unit, and an air conditioner, which can improve the technical problem of poor air outlet effect of the air outlet 110 in the prior art.

[0050] 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 scope of protection of the present invention should be based on the scope defined by the claims.
