Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to a vertical air conditioning indoor unit with curtain support. Background Technology

[0002] With the development of science and technology, the number of air conditioners in use is increasing, playing a vital role in people's lives, work, and entertainment. Floor-standing air conditioners, in particular, are popular due to their large airflow, high cooling capacity, and wide applicable cooling area. Typically, the indoor unit of a floor-standing air conditioner is installed in a corner, and the air inlet is designed at the rear. However, according to most users' habits, curtains are usually hung in the corner. Whether the curtains are open or closed, they will block the air inlet of the floor-standing air conditioner, affecting air intake and reducing its performance.

[0003] Currently, in existing technologies, to solve the problem of curtains obstructing the air intake, a detachable curtain bracket is usually installed at the air intake of the indoor unit of a floor-standing air conditioner, keeping the curtain away from the air intake. Specifically, during the air conditioner's transportation, the curtain bracket is packed in the packaging accessory bag; when the user needs the curtain bracket, it is then installed at the air intake of the indoor unit. However, during air conditioner transportation, the curtain bracket occupies transport space, increasing transportation costs; and after the indoor unit leaves the factory, both installers and users need to reinstall the curtain bracket, making its use quite cumbersome.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0055] The following is combined with Figures 1 to 9 The vertical air conditioner indoor unit of this embodiment will be described in detail below.

[0056] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In this embodiment, the indoor unit of the vertical air conditioner may include a housing 100 and a curtain support 200.

[0057] An air inlet 121 is provided on the rear side of the housing 100, and a rearward-opening receiving cavity 122 is provided on the rear side of the housing 100, with the receiving cavity 122 adjacent to the air inlet 121.

[0058] The curtain support 200 is movably disposed within the receiving cavity 122. The curtain support 200 has a retracted state that is housed within the receiving cavity 122 and an extended state that extends out of the receiving cavity 122. The curtain support 200 is used to limit the contact between the curtain and the air inlet 121 in the extended state.

[0059] Because the vertical air conditioner indoor unit of this embodiment has an added receiving cavity 122, and the curtain support 200 can be stored inside or extended out of the receiving cavity 122, the curtain support 200 can be stored inside the receiving cavity 122 during transportation, eliminating the need to pack it in the accessory bag. During use, the curtain support 200 can extend out of the receiving cavity 122 to limit contact between the curtain and the air inlet 121, eliminating the need for installation and making its use very simple and convenient. Therefore, this embodiment reduces the transportation cost of the vertical air conditioner indoor unit, simplifies the operation of the curtain support 200, and improves the user experience.

[0060] Reference Figure 3 and Figure 5 In this embodiment, the receiving cavity 122 extends in the left-right direction; and the curtain support 200 may include a first curtain bracket 210 and a second curtain bracket 220.

[0061] One end of the first curtain bracket 210 is rotatably disposed at the left end of the receiving cavity 122, and the rotation axis of the first curtain bracket 210 is arranged in the vertical direction so as to be rotatably stored in the receiving cavity 122 to the right front or to be rotatably supported out of the receiving cavity 122.

[0062] One end of the second curtain bracket 220 is rotatably disposed at the right end of the receiving cavity 122, and the rotation axis of the second curtain bracket 220 is arranged in the vertical direction so as to be rotatably stored in the receiving cavity 122 to the left front or to be rotatably supported out of the receiving cavity 122.

[0063] It is understandable that the curtain support 200 can be rotatably mounted within the receiving cavity 122, allowing it to be either stored within or extended out of the receiving cavity 122. Specifically, by configuring the curtain support 200 as a double-door structure, i.e., one end of the first curtain bracket 210 is rotatably mounted on the left end of the receiving cavity 122 with its rotation axis oriented vertically, and one end of the second curtain bracket 220 is rotatably mounted on the right end of the receiving cavity 122 with its rotation axis oriented vertically, the first curtain bracket 210 and the second curtain bracket 220 can be rotatably stored within or extended out of the receiving cavity 122, thereby reducing the transportation cost of the vertical air conditioner indoor unit and simplifying the operation of the curtain support 200.

[0064] Reference Figure 4 In this embodiment, when the curtain support 200 is in the retracted state, the outer sides of the first curtain bracket 210 and the second curtain bracket 220 are flush with the outer side of the housing 100.

[0065] Understandably, when the unit is folded up, the outer sides of the first curtain bracket 210 and the second curtain bracket 220 are flush with the outer side of the housing 100, which can effectively ensure the appearance of the rear side of the housing 100 and maintain the aesthetics of the vertical air conditioner indoor unit.

[0066] Reference Figure 3 and Figure 5 In this embodiment, when the curtain support 200 is in the extended state, the other ends of the first curtain bracket 210 and the second curtain bracket 220 are respectively positioned rearward.

[0067] Understandably, in the deployed state, the other ends of the first curtain bracket 210 and the second curtain bracket 220 are respectively set to the rear, which can well ensure their support effect on the curtain, ensure the curtain support 200 restricts the curtain from approaching or contacting the air inlet 121, and further ensure the air intake of the vertical air conditioner indoor unit and ensure the working performance of the vertical air conditioner indoor unit.

[0068] Reference Figure 3 and Figure 5 In this embodiment, the curtain support 200 may further include a first rotating shaft 230 and a second rotating shaft 240 disposed in the receiving cavity 122. The first rotating shaft 230 and the second rotating shaft 240 are respectively disposed at the left end and the right end of the receiving cavity 122, and both the first rotating shaft 230 and the second rotating shaft 240 are disposed in the vertical direction. Furthermore, the first curtain bracket 210 may include a first bracket plate 211 and a first support 212, and the second curtain bracket 220 may include a second bracket plate 221 and a second support 222.

[0069] The first support 212 is disposed on the inner side of the first support plate 211 and is located at the left end of the first support plate 211. The first support 212 has a first shaft hole 2121 that opens upward and downward, and the first shaft hole 2121 is rotatably sleeved on the first rotating shaft 230.

[0070] The second support 222 is disposed on the inner side of the second support plate 221 and is located at the right end of the second support plate 221. The second support 222 has a second shaft hole 2221 that opens upward and downward, and the second shaft hole 2221 is rotatably sleeved on the second rotating shaft 240.

[0071] Understandably, the first support 212 and its first shaft hole 2121 and first rotating shaft 230 allow one end of the first curtain bracket 210 to be rotatably disposed at the left end of the receiving cavity 122, so that the first curtain bracket 210 can be rotated to the right front to be stored in the receiving cavity 122 or rotated to the rear to support the receiving cavity 122; the second support 222 and its second shaft hole 2221 and second rotating shaft 240 allow one end of the second curtain bracket 220 to be rotatably disposed at the right end of the receiving cavity 122, so that the second curtain bracket 220 can be rotated to the left front to be stored in the receiving cavity 122 or rotated to the rear to support the receiving cavity 122, thereby reducing the transportation cost of the vertical air conditioner indoor unit and simplifying the use of the curtain support 200.

[0072] Reference Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 In this embodiment, the first curtain bracket 210 may further include a first support 213. The second curtain bracket 220 may further include a second support 223.

[0073] The first support 213 is disposed on the inner side of the first support plate 211. The first support 213 is located at the right end of the first support plate 211 and extends away from the inner side of the first support plate 211. The sum of the thickness D of the first support plate 211 and the extension length F of the first support 213 is the same as the depth H of the receiving cavity 122 in the front-back direction. The sum of the first shaft front distance of the first rotating shaft 230 and the first hole outer distance of the first shaft hole 2121 is the same as the depth H of the receiving cavity 122 in the front-back direction. The first shaft front distance is the distance I between the first rotating shaft 230 and the front cavity wall 125 of the receiving cavity 122, and the first hole outer distance is the distance K between the first shaft hole 2121 and the outer side of the first support plate 211.

[0074] The second support 223 is disposed on the inner side of the second support plate 221. The second support 223 is located at the left end of the second support plate 221 and extends away from the inner side of the second support plate 221. The sum of the thickness E of the second support plate 221 and the extension length G of the second support 223 is the same as the depth H of the receiving cavity 122 in the front-back direction. The sum of the second shaft front distance of the second rotating shaft 240 and the second hole outer distance of the second shaft hole 2221 is the same as the depth H of the receiving cavity 122 in the front-back direction. The second shaft front distance is the distance J between the second rotating shaft 240 and the front cavity wall 125 of the receiving cavity 122, and the second hole outer distance is the distance L between the second shaft hole 2221 and the outer side of the second support plate 221.

[0075] It is understandable that the sum of the thickness D of the first bracket plate 211 and the extension length F of the first support body 213 is the same as the depth H of the receiving cavity 122 in the front-rear direction. Similarly, the sum of the first shaft front distance of the first rotating shaft 230 and the first hole outer distance of the first shaft hole 2121 is the same as the depth H of the receiving cavity 122 in the front-rear direction. This allows the first curtain bracket 210 to be flush with the outer side of the housing 100 when the curtain support 200 is in the retracted state, ensuring the aesthetics of the rear side of the vertical air conditioner indoor unit. Likewise, the sum of the thickness E of the second bracket plate 221 and the extension length G of the second support body 223 is the same as the depth H of the receiving cavity 122 in the front-rear direction. Similarly, the sum of the second shaft front distance of the second rotating shaft 240 and the second hole outer distance of the second shaft hole 2221 is the same as the depth H of the receiving cavity 122 in the front-rear direction. This allows the second curtain bracket 220 to be flush with the outer side of the housing 100 when the curtain support 200 is in the retracted state, ensuring the aesthetics of the rear side of the vertical air conditioner indoor unit.

[0076] Reference Figure 6 , Figure 7 and Figure 8 In this embodiment, the sum of the length M of the first support plate 211 and the length N of the second support plate 221 is less than or equal to the length P of the receiving cavity 122 in the left-right direction; and the width Q of the first support plate 211 and the second support plate 221 in the up-down direction is less than or equal to the width R of the receiving cavity 122 in the up-down direction.

[0077] It is understandable that the sum of the length M of the first support plate 211 and the length N of the second support plate 221 is set to be less than or equal to the length P of the receiving cavity 122 in the left-right direction, and the width Q of the first support plate 211 and the second support plate 221 in the up-down direction is set to be less than or equal to the width R of the receiving cavity 122 in the up-down direction. This allows the first support plate 211 and the second support plate 221 to be housed in the receiving cavity 122, and the gaps between the first support plate 211 and the second support plate 221 and the housing 100 can be minimized, further ensuring the aesthetics of the rear side of the vertical air conditioner indoor unit.

[0078] Reference Figure 3 , Figure 6 and Figure 7 In this embodiment, the portion of the first support 212 away from the first bracket plate 211 has a first mounting notch 2122, which is connected to the first shaft hole 2121, and the width S of the first mounting notch 2122 along the length direction of the first bracket plate 211 is less than or equal to the diameter of the first shaft hole 2121; and the portion of the second support 222 away from the second bracket plate 221 has a second mounting notch 2222, which is connected to the second shaft hole 2221, and the width T of the second mounting notch 2222 along the length direction of the second bracket plate 221 is less than or equal to the diameter of the second shaft hole 2221.

[0079] Understandably, the design of the first mounting notch 2122 and the second notch allows both the first curtain bracket 210 and the second curtain bracket 220 to be easily installed within the receiving cavity 122, ensuring ease of assembly for both. Furthermore, by setting the width S of the first mounting notch 2122 along the length of the first bracket plate 211 to be less than or equal to the diameter of the first shaft hole 2121, and setting the width T of the second mounting notch 2222 along the length of the second bracket plate 221 to be less than or equal to the diameter of the second shaft hole 2221, the connection stability of the first curtain bracket 210 and the second curtain bracket 220 rotatably mounted within the receiving cavity 122 is effectively ensured.

[0080] Reference Figure 1 , Figure 2 and Figure 5 In this embodiment, the housing 100 may include a front side housing 110 and a rear side housing 120 that are fastened together. The rear side housing 120 is located behind the front side housing 110, and the air inlet 121 and the receiving cavity 122 are both located on the rear side housing 120.

[0081] It is understandable that by splitting the housing 100 into a front housing 110 and a rear housing 120, the assembly difficulty of the vertical air conditioner indoor unit is reduced, and the assembly efficiency of the vertical air conditioner indoor unit is ensured.

[0082] Reference Figure 2 and Figure 5 In this embodiment, an air inlet grille 123 is provided on the air inlet 121. The air inlet grille 123 can filter out large debris in the incoming airflow, so that large debris will not enter the interior of the vertical air conditioner indoor unit from the air inlet 121, thus ensuring the normal operation of the vertical air conditioner indoor unit.

[0083] Reference Figure 2 , Figure 4 and Figure 5 In this embodiment, the air intake grille 123 may include at least one grille support frame 1231 extending in the left-right direction.

[0084] It is understood that the grille support frame 1231 may include horizontal and vertical grille bars and the grille support frame 1231 extending in the left and right directions. The width of the support frame in the vertical direction is greater than the width of the grille bars. Therefore, the grille support frame 1231 can well ensure the overall structural strength of the air intake grille 123, and further ensure the structural strength of the rear shell 120.

[0085] In this embodiment, the number of grille support frames 1231 can be set to multiple, and the multiple grille support frames 1231 are arranged at intervals in the vertical direction to further ensure the overall structural strength of the air intake grille 123 and the structural strength of the rear shell 120. Furthermore, horizontal and vertical grille strips are arranged between the multiple grille support frames 1231.

[0086] Reference Figure 2 and Figure 5 In this embodiment, the number of receiving cavities 122 can be set to multiple, and the multiple receiving cavities 122 are respectively disposed on the portion of the rear shell 120 above the air inlet grille 123, the portion of the rear shell 120 below the air inlet grille 123, and at least one grille support frame 1231; and the number of curtain support members 200 is set to multiple, and the curtain support members 200 are correspondingly disposed in the receiving cavities 122.

[0087] It is understandable that multiple accommodating cavities 122 and curtain support members 200 can be provided to further ensure the limiting effect of curtain support members 200 on the curtain's approach to or contact with the air inlet 121.

[0088] Reference Figure 2 , Figure 3 , Figure 4In this embodiment, the outer side of the middle part of the rear shell 120 along the left and right direction includes the rear shell plane 124, the outer side of the middle part of the grid support frame 1231 along the left and right direction includes the grid plane 1232, a plurality of receiving cavities 122 are respectively disposed at the rear shell plane 124 and the grid plane 1232, and the first support plate 211 and the second support plate 221 are configured as flat plate structures.

[0089] It is understandable that by making the outer side of the rear shell 120 where the receiving cavity 122 is located flat, and by making the first support plate 211 and the second support plate 221 into flat structures, the consistency of appearance between the first curtain bracket 210 and the second curtain bracket 220 and the shell 100 (or the rear shell 120) can be well ensured when the curtain support 200 is in the retracted state, thus guaranteeing the aesthetics of the rear side of the shell 100. Furthermore, by making the first support plate 211 and the second support plate 221 into flat structures, when the receiving cavity 122 extends a certain length in the lateral direction, the first support plate 211 and the second support plate 221 have the longest extension length in the front-back direction when the curtain support 200 is in the extended state, further restricting the curtain support 200 from approaching or contacting the air inlet 121.

[0090] Reference Figure 8 and Figure 9 In this embodiment, the rear shell 120 may include a front cavity wall 125, a left cavity wall 126, a right cavity wall 127, a top cavity wall 128, and a bottom cavity wall 129 for forming the receiving cavity 122. The front cavity wall 125 is located in front of the receiving cavity 122. The left cavity wall 126 is connected to the front cavity wall 125 and is located to the left of the receiving cavity 122. The right cavity wall 127 is connected to the front cavity wall 125 and is located to the right of the receiving cavity 122. The top cavity wall 128 is connected to the left cavity wall 126, the right cavity wall 127, and the front cavity wall 125 and is located above the receiving cavity 122. The bottom cavity wall 129 is connected to the left cavity wall 126, the right cavity wall 127, and the front cavity wall 125 and is located below the receiving cavity 122.

[0091] Reference Figure 7 In this embodiment, reinforcing ribs 250 are provided between the first support body 213 and the first bracket plate 211, and between the second support body 223 and the second bracket plate 221, to ensure the connection strength between the first support body 213 and the first bracket plate 211, and the connection strength between the second support body 223 and the second bracket plate 221.

[0092] In some other embodiments, a first damping structure may be provided between the first shaft hole 2121 and the first rotating shaft 230; and a second damping structure may be provided between the second shaft hole 2221 and the second rotating shaft 240, so as to improve the stability of the curtain support 200 in the extended state, and prevent the first curtain bracket 210 and the second curtain bracket 220 from being retracted into the receiving cavity 122 due to the excessive weight of the curtain, thereby further enhancing the limiting effect of the curtain support 200 on the curtain approaching or contacting the air inlet 121.

[0093] In the first embodiment of the damping structure, the first damping structure and the second damping structure can be respectively set as the frosted contact surface between the first shaft hole 2121 and the first rotating shaft 230 and the frosted contact surface between the second shaft hole 2221 and the second rotating shaft 240, so as to ensure the stability of the curtain support 200 in the extended state.

[0094] In a second embodiment of the damping structure, the first damping structure may be at least one damping protrusion disposed on the wall of the first shaft hole 2121 and a plurality of damping grooves distributed on the peripheral wall of the first rotating shaft 230. When the curtain support 200 is in the extended state, the damping protrusion can be embedded in the damping groove to achieve a damping effect. Furthermore, the second damping structure may have the same structure as the first damping structure.

[0095] In some other embodiments, the first shaft hole 2121 and the first rotating shaft 230, as well as the second shaft hole 2221 and the second rotating shaft 240, can be a transition fit or an interference fit to ensure the stability of the curtain support 200 in the extended state.

[0096] In some other embodiments, the difference from the above embodiments lies in that the curtain support 200 can be telescopically disposed within the receiving cavity 122. Specifically, slide rails are arranged at both ends of the receiving cavity 122 along the front-back direction, and sliders can be correspondingly provided at both ends of the curtain support 200, with the sliders slidably disposed within the slide rails. This allows the curtain support 200 to be housed within the receiving cavity 122 and to be supported backwards out of the receiving cavity 122. Furthermore, a locking structure can be provided on the slide rails, which can be used to lock the sliders on the slide rails when the curtain support 200 is in the extended state, restricting the sliding of the sliders on the slide rails to ensure the stability of the curtain support 200 in the extended state. Further, the curtain support 200 can be a first curtain bracket 210 and a second curtain bracket 220 respectively arranged along the front-back direction, with sliders provided on both the first curtain bracket 210 and the second curtain bracket 220, or the curtain support 200 can be a frame structure formed by connecting multiple rods, with sliders disposed on the left and right sides of the frame structure.

[0097] In some other embodiments, the curtain support 200 is retractably disposed within the receiving cavity 122 by replacing the aforementioned slider and rail structure with an electric push rod.

[0098] In some other embodiments, the difference from the above embodiments lies in that the receiving cavity 122 may be arranged to extend vertically. Correspondingly, one end of the first curtain bracket 210 is rotatably disposed at the top of the receiving cavity 122, and the rotation axis of the first curtain bracket 210 is arranged in the left-right direction, so that the first curtain bracket 210 is rotatably housed in the receiving cavity 122 downward and forward or rotatably supported out of the receiving cavity 122; and one end of the second curtain bracket 220 is rotatably disposed at the bottom of the receiving cavity 122, and the rotation axis of the second curtain bracket 220 is arranged in the vertical direction, so that the second curtain bracket 220 is rotatably housed in the receiving cavity 122 upward and forward or rotatably supported out of the receiving cavity 122. Furthermore, multiple receiving cavities 122 may also be arranged on the left and right sides of the air inlet 121.

[0099] In some other embodiments, the receiving cavity 122 may not have a cavity wall. That is, a receiving through hole is directly opened on the rear shell 120 (or the rear shell 120 of the housing 100), and an unclosed receiving space (receiving cavity 122) is provided in the rear shell 120 (or the rear shell 120 of the housing 100) at the position corresponding to the receiving through hole. In this way, the curtain support 200 can also be housed in the receiving space in the rear shell 120 (or the rear shell 120 of the housing 100) through the receiving through hole, or supported outside the rear shell 120 (or the rear shell 120 of the housing 100) through the receiving through hole.

[0100] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
