Description

Technical Field

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

[0002] Existing air conditioner casings can be manufactured in an integrated manner through the middle frame, panel, and side panels, reducing the complexity of casing manufacturing and assembly. However, the integrated manufacturing of air conditioner casings limits the appearance of the air conditioner, resulting in the air conditioner's appearance being mostly flat and single, making it difficult to meet the user's personalized needs. Summary of the Invention

[0003] The problem solved by the present invention is that the exterior surfaces of existing indoor units are mostly flat and have a single appearance, which makes it difficult to meet the personalized needs of users.

[0004] In order to solve the above problems, in a first aspect, the present invention provides an air conditioner housing, the air conditioner housing comprising:

[0005] The shell body is provided with an air outlet, and an extension plate is provided on the inner edge of the air outlet;

[0006] A side panel is connected to the side end of the shell body, and a decorative protrusion is provided on the outer side surface of the side panel;

[0007] Wherein, along the length direction of the shell body, the ratio of the distance L1 from the decorative protrusion to the side panel to the distance L2 from the side panel to the extension panel is in the range of 7% to 12%.

[0008] The air conditioner housing provided by the present invention has at least the following beneficial effects:

[0009] 1. Decorative convex parts are set on the outer surface of the side panel, which changes the traditional flat appearance, increases the aesthetics of the air conditioner and meets the personalized needs of users;

[0010] 2. The ratio of the distance L1 from the decorative protrusion to the side panel to the distance L2 from the side panel to the extension panel is designed to be in the range of 7% to 12%. This not only ensures the aesthetics brought by the decorative protrusion, but also prevents the distance L2 from the side panel to the extension panel from being significantly increased, and the length of the air conditioner casing from being significantly increased. In addition, the distance L2 from the side panel to the extension panel is sufficient for the mold for manufacturing the decorative protrusion to be pulled out from the space between the side panel and the extension panel, thereby facilitating the molding of the decorative protrusion without increasing the difficulty of manufacturing.

[0011] In an optional embodiment, the ratio of the distance L1 from the decorative protrusion to the side panel to the distance L2 from the side panel to the extension panel is in the range of 10% to 12%.

[0012] Thus, the ratio of L1 to L2 is in the range of 10% to 12%, which not only satisfies the requirement that the mold for manufacturing the decorative protrusion can be pulled out of the air conditioner casing, but also makes the protruding size of the decorative protrusion more aesthetically pleasing.

[0013] In an optional embodiment, the distance L1 from the decorative protrusion to the side panel ranges from 4 mm to 6 mm.

[0014] In this way, the decorative protrusion protrudes 4 mm to 6 mm relative to the side panel, which is easy to manufacture and has better aesthetics.

[0015] In an optional embodiment, the distance L2 from the side plate to the extension plate ranges from 40 mm to 50 mm.

[0016] In this way, the distance between the side plate and the extension plate is 40 mm to 50 mm, which not only does not significantly increase the length of the air conditioner casing, but also meets the requirements of the mold for extracting the air conditioner casing.

[0017] In an optional embodiment, the distance L2 from the side plate to the extension plate is greater than or equal to the width H1 of the head of the mold for forming the decorative protrusion.

[0018] In this way, the distance L2 from the side panel to the extension panel is the avoidance distance for the head of the mold to be pulled out of the air-conditioning casing. This avoidance distance is greater than or equal to the width H1 of the head of the mold, which is sufficient to ensure that the head of the mold can be pulled out of the air-conditioning casing from the space between the side panel and the extension panel.

[0019] In an optional embodiment, a length L3 of the decorative protrusion along the vertical direction of the side panel is greater than or equal to 250 mm.

[0020] In this way, the length L3 of the decorative protrusion along the vertical direction of the side panel is larger, which better beautifies the side panel.

[0021] In an optional embodiment, the ratio of the width L4 of the decorative protrusion along the left-right direction of the side panel to the length L3 of the decorative protrusion along the up-down direction of the side panel is in the range of 30% to 50%.

[0022] In this way, the width L4 of the decorative protrusion along the left and right directions of the side panel is relatively moderate. If the width L4 is larger, the head of the mold used to form the decorative protrusion will be larger in size and heavier in weight, and the root connecting the head on the mold will be subjected to greater force, which may easily cause the root to break.

[0023] In an optional embodiment, the ratio of the width L4 of the decorative protrusion along the left-right direction of the side panel to the width L5 of the side panel along the left-right direction ranges from 50% to 70%.

[0024] In this way, the width L4 of the decorative protrusion along the left and right directions of the side panel is more moderate than the width L5 of the left and right directions of the side panel. Not only does the decorative protrusion better beautify the side panel, but the head size of the mold used to form the decorative protrusion is more appropriate, and there will be no problem of the head being too heavy or too large.

[0025] In an alternative embodiment, the decorative protrusion is connected to the front edge of the side panel.

[0026] Because users generally mainly observe the front surface of the air conditioner casing, designing the decorative protrusion close to the front edge of the side panel can further improve the appearance of the air conditioner casing.

[0027] In a second aspect, the present invention provides an indoor unit, comprising the air conditioner casing according to any one of the aforementioned embodiments.

[0028] In this way, the indoor unit provided by the present invention not only has a good appearance, but also can be easily manufactured. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] 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.

[0038] First embodiment

[0039] See also Figure 1 and Figure 2 This embodiment provides an air conditioner housing 100, which includes a housing body 110 and side panels 130. The housing body 110 is provided with an air outlet 111, which extends along the length of the housing body 110. An extension plate 120 is provided on the inner edge of the air outlet 111, and the extension plate 120 is substantially perpendicular to the length of the air outlet 111. The extension plate 120 is used to guide the air blown out of the housing body 110 to be blown out through the air outlet 111.

[0040] The "approximately vertical" here can generally be understood as an angle between 80-110 degrees. In other words, a strict 90-degree verticality is not required.

[0041] The side panel 130 is connected to the side end of the shell body 110. A decorative protrusion 140 is provided on the outer surface of the side panel 130, which changes the traditional flat appearance, increases the beauty of the air conditioner appearance, and meets the personalized needs of users.

[0042] See also Figure 2 and Figure 3 There are many options for the shape of the decorative protrusion 140. For example, the outline of the decorative protrusion 140 can be a waist-shaped hole shape, an ellipse, a circle or a polygon. The shape of the central protrusion of the decorative protrusion 140 can be a regular shape or an irregular shape, as long as it has a shape that increases the aesthetics.

[0043] In this embodiment, the contour of the decorative protrusion 140 is in the shape of a waist-shaped hole, the central protrusion of the decorative protrusion 140 can also be in the shape of a waist-shaped hole, and star-shaped grooves are designed on the periphery of the central protrusion, which has good ornamental value as a whole.

[0044] The decorative protrusion 140 is located closer to the front edge 131 of the side panel 130 than the rear edge 132 of the side panel 130. Preferably, the decorative protrusion 140 is connected to the front edge 131 of the side panel 130. Here, the rear edge 132 of the side panel 130 refers to the edge of the side panel 130 that is closer to the wall when the air conditioner housing 100 is actually in use, and the front edge 131 refers to the edge of the side panel 130 that is farther away from the wall. Because users generally primarily view the front surface of the air conditioner housing 100, designing the decorative protrusion 140 closer to the front edge 131 of the side panel 130 improves the appearance of the air conditioner housing 100 and allows users to directly view the decorative protrusion 140.

[0045] See also Figure 3The length L3 of the decorative protrusion 140 along the vertical direction of the side panel 130 is greater than or equal to 250 mm. When the air conditioner housing 100 is actually in use, the side panel 130 is in a vertical position, and the vertical direction of the side panel 130 is the vertical direction. In this way, the length L3 of the decorative protrusion 140 along the vertical direction of the side panel 130 is larger, which better beautifies the side panel 130.

[0046] Preferably, the length L3 of the decorative protrusion 140 along the vertical direction of the side panel 130 can extend to the upper and lower edges of the side panel 130 to maximize the length L3 of the decorative protrusion 140. In this embodiment, the length L3 of the decorative protrusion 140 along the vertical direction of the side panel 130 can range from 250 mm to the vertical length of the side panel 130, specifically 265 mm.

[0047] The ratio of the width L4 of the decorative protrusion 140 along the side panel 130 in the left-right direction to the length L3 of the decorative protrusion 140 along the side panel 130 in the vertical direction is in the range of 30% to 50%, where the left-right direction of the side panel 130 is defined as the horizontal direction. Thus, the width L4 of the decorative protrusion 140 along the side panel 130 is moderate. If the width L4 is too large, the head portion 210 of the mold 200 used to form the decorative protrusion 140 will be larger and heavier, and the root portion 220 of the mold 200 connected to the head portion 210 will be subjected to greater stress, which may easily cause the root portion 220 to break.

[0048] Specifically, the width L4 of the decorative protrusion 140 along the left-right direction of the side panel 130 may be in the range of 110 mm to 130 mm, and may be specifically 118 mm.

[0049] The ratio of the width L4 of the decorative protrusion 140 along the left-right direction of the side panel 130 to the width L5 of the side panel 130 in the left-right direction is in the range of 50% to 70%. Thus, the width L4 of the decorative protrusion 140 along the left-right direction of the side panel 130 is moderate relative to the width L5 of the side panel 130 in the left-right direction. This not only improves the aesthetics of the decorative protrusion 140 on the side panel 130, but also ensures that the head 210 of the mold 200 used to form the decorative protrusion 140 is of a suitable size, preventing the head 210 from being too heavy or too bulky.

[0050] Specifically, the width L5 of the side panel 130 in the left-right direction may be in the range of 170 mm to 200 mm, and may be specifically 185 mm.

[0051] See also Figure 4 and Figure 5Along the length of the housing body 110, the ratio of the distance L1 between the decorative protrusion 140 and the side panel 130 to the distance L2 between the side panel 130 and the extension panel 120 is in the range of 7% to 12%, preferably 10% to 12%. This L1 to L2 ratio of 7% to 12% not only ensures that the mold 200 for manufacturing the decorative protrusion 140 can be removed from the air conditioner housing 100, but also makes the raised size of the decorative protrusion 140 more aesthetically pleasing.

[0052] Specifically, the distance L1 between the decorative protrusion 140 and the side panel 130 is in the range of 4 mm to 6 mm. In this way, the decorative protrusion 140 is raised by 4 mm to 6 mm relative to the side panel 130, which is easy to manufacture and has a better aesthetic appearance.

[0053] The distance L2 between the side panel 130 and the extension panel 120 is in the range of 40 mm to 50 mm. Thus, the distance between the side panel 130 and the extension panel 120 is 40 mm to 50 mm, which not only does not significantly increase the length of the air conditioner housing 100, but also satisfies the requirement of the mold 200 to extract the air conditioner housing 100.

[0054] See also Figure 6 The distance L2 between the side panel 130 and the extension panel 120 is greater than or equal to the width H1 of the head portion 210 of the mold 200 used to form the decorative protrusion 140. Thus, the distance L2 between the side panel 130 and the extension panel 120 is the clearance distance for the head portion 210 of the mold 200 to be withdrawn from the air conditioner casing 100. This clearance distance is also greater than or equal to the width H1 of the head portion 210 of the mold 200, sufficient to ensure that the head portion 210 of the mold 200 can be withdrawn from the air conditioner casing 100 through the space between the side panel 130 and the extension panel 120.

[0055] Specifically, the mold 200 for molding the decorative protrusion 140 includes a head 210 and a root 220 connected to each other. The root 220 is used to support the head 210. The head 210 is used to form the decorative protrusion 140 during the injection molding process. The width of the head 210 is greater than the width of the root 220.

[0056] In order to ensure that the head 210 can be pulled out from the air-conditioning casing 100, the distance L2 from the side panel 130 to the extension panel 120 is designed to be greater than the sum of the distance L1 from the decorative protrusion 140 to the side panel 130 and the width H1 of the head 210 of the mold 200 used to form the decorative protrusion 140. In this way, the pulling-out direction of the mold 200 is: first, the mold 200 moves from the decorative protrusion 140 to the extension panel 120, and then, the mold 200 is pulled upward from the gap between the side panel 130 and the extension panel 120 as a whole, thereby completing the operation of pulling out the mold 200.

[0057] According to the conventional dimensions of the mold 200 and the air-conditioning casing 100, in this embodiment, the ratio of the distance L1 from the decorative protrusion 140 to the side panel 130 to the distance L2 from the side panel 130 to the extension panel 120 is designed to be in the range of 7% to 12%. This not only ensures the aesthetics brought by the decorative protrusion 140, but also prevents the distance L2 from the side panel 130 to the extension panel 120 from becoming significantly larger, and the length of the air-conditioning casing 100 from increasing significantly, but also ensures that the distance L2 from the side panel 130 to the extension panel 120 is sufficient for the mold 200 for manufacturing the decorative protrusion 140 to be pulled out from the space between the side panel 130 and the extension panel 120, thereby facilitating the molding of the decorative protrusion 140 without increasing the difficulty of manufacturing.

[0058] The air conditioner housing 100 provided in this embodiment can be integrally formed, that is, the housing body 110, the extension plate 120, the side plate 130 and the decorative protrusion 140 can be injection molded simultaneously through a set of molds. This not only allows for quick processing, reduces the number of parts, eliminates the need for assembly, but also increases overall structural strength.

[0059] This embodiment further provides an indoor unit, which includes the air conditioner housing 100 described above. Of course, the indoor unit also includes conventional air conditioner components, such as an evaporator, an air guide door, an auxiliary heater, etc., which are not described in detail here. Thus, the indoor unit provided by this embodiment not only has a good appearance, but also can be easily manufactured.

[0060] The air conditioner housing 100 and the indoor unit provided in this embodiment have the following beneficial effects:

[0061] 1. The decorative protrusion 140 is provided on the outer surface of the side panel 130, which changes the traditional flat appearance, improves the appearance of the air conditioner, and meets the personalized needs of users;

[0062] 2. The ratio of the distance L1 between the decorative protrusion 140 and the side panel 130 to the distance L2 between the side panel 130 and the extension panel 120 is designed to be in the range of 7% to 12%. This not only ensures the aesthetics of the decorative protrusion 140, but also prevents the distance L2 from the side panel 130 to the extension panel 120 from being significantly increased, thus preventing the length of the air conditioner casing 100 from being significantly increased. Furthermore, the distance L2 between the side panel 130 and the extension panel 120 is sufficient to allow the mold 200 for manufacturing the decorative protrusion 140 to be withdrawn from the space between the side panel 130 and the extension panel 120, thereby facilitating the molding of the decorative protrusion 140 without increasing the manufacturing difficulty.

[0063] 3. The length L3 of the decorative protrusion 140 along the vertical direction of the side panel 130 is greater than or equal to 250 mm. In this way, the length L3 of the decorative protrusion 140 along the vertical direction of the side panel 130 is large, which better beautifies the side panel 130;

[0064] 4. The ratio of the width L4 of the decorative protrusion 140 along the left-right direction of the side panel 130 to the width L5 of the side panel 130 is in the range of 50% to 70%. Thus, the width L4 of the decorative protrusion 140 along the left-right direction of the side panel 130 is moderate relative to the width L5 of the side panel 130. This not only improves the aesthetics of the decorative protrusion 140 on the side panel 130 but also ensures that the head 210 of the mold 200 used to form the decorative protrusion 140 is of a suitable size, preventing the head 210 from being excessively heavy or bulky.

[0065] 5. Because users generally mainly observe the front surface of the air conditioner housing 100, designing the decorative protrusion 140 close to the front edge 131 of the side panel 130 can further improve the appearance of the air conditioner housing 100.

[0066] 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.
