Description

Technical Field

[0001] This utility model belongs to the field of air conditioning technology, specifically relating to a reversible air conditioner bottom shell assembly with up and down air outlet and an air conditioner indoor unit. Background Technology

[0002] In current single-flow reversible top-and-bottom air-discharge air conditioners, the airflow direction is mainly changed by switching the positions of the rotating volute and the spoiler. However, the gaps between the volute tongue, volute throat, and cross-flow fan blades of the rotating volute are all small, making the assembly of the rotating volute and spoiler parts difficult.

[0003] In addition, the motion mechanism of the rotating volute needs to be designed on both sides of the air duct. However, the conventional cross-flow fan blades have motor pressure plates and angle brackets on both sides. If the motion mechanism of the rotating volute is designed according to the conventional scheme, slide rails, racks, etc. need to be arranged on multiple parts such as pressure plates, angle brackets, and bottom shells, which is very difficult to install and has very low reliability.

[0008] Furthermore, the first mounting part and the first clamping part cooperate to form a bearing mounting space for mounting the bearing; the second mounting part and the second clamping part cooperate to form a motor mounting space for mounting the motor.

[0013] Furthermore, the rotating mechanism also includes two second rotating components disposed at both ends of the side wall of the upper bottom shell; the second rotating components are used to limit the rotation of the rotating volute; the second rotating components include a second protruding shaft disposed on the rotating volute; a second sliding groove is also provided on the side wall of the upper bottom shell, and the second protruding shaft can slide through the second sliding groove.

[0042] like Figures 1 to 6 As shown, this embodiment of the utility model provides a reversible top-and-bottom air conditioner base shell assembly. The base shell assembly is divided into a lower base shell assembly 1 and an upper base shell assembly 2, which facilitates the assembly of parts such as the rotating volute 22 and spoilers during manufacturing or maintenance, avoiding damage or even breakage of parts due to insufficient assembly space. The lower base shell assembly 1 includes a lower base shell 11 and a cross-flow fan blade 12 pre-installed on the lower base shell 11. The upper base shell assembly 2 includes an upper base shell 21 and a rotating volute 22 pre-installed on the upper base shell 21. The lower base shell 11 and the upper base shell 21 are detachably connected. An upper air inlet is formed between the top of the upper base shell 21 and the lower base shell 11, and a lower air inlet is formed between the bottom of the upper base shell 21 and the lower base shell 11, for air intake and exhaust. The two sides of the rotating volute 22 are rotatably mounted on the upper bottom shell sidewalls 23 at both ends of the upper bottom shell 21 via a rotating mechanism, thereby simplifying the installation structure of the rotating volute 22 and solving the problem of difficult assembly of parts such as the rotating volute 22 and the spoiler in the air conditioning indoor unit.

[0043] Specifically, when the rotating volute 22 rotates to the first position at the top of the cross-flow fan blade 12, the air conditioner bottom housing assembly is adapted to the air outlet mode of upward air outlet and downward air inlet; when the rotating volute 22 rotates to the second position at the bottom of the cross-flow fan blade 12, the air conditioner bottom housing assembly is adapted to the air outlet mode of downward air outlet and upward air inlet; thereby realizing the upward and downward air outlet of the single cross-flow air conditioner indoor unit.

[0044] Preferably, in combination with the above schemes, such as Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, in one embodiment of the present utility model, a first mounting part 13 is provided at one end of the lower bottom shell 11, and a second mounting part 15 is provided at the other end; a first pressing part 24 adapted to the first mounting part 13 and a second pressing part 25 adapted to the second mounting part 15 are respectively provided at both ends of the upper bottom shell 21.

[0045] By connecting the first clamping part 24 to the first mounting part 13 and the second clamping part 25 to the second mounting part 15, a detachable connection between the lower bottom shell 11 and the upper bottom shell 21 can be achieved; this facilitates the subsequent assembly of components such as heat exchangers, and the assembly scheme is simple, reasonable, and easy to operate.

[0046] In some possible embodiments, the first clamping part 24 and the second clamping part 25 are respectively disposed in a plurality of self-tapping screw through holes and a plurality of screw posts that match the self-tapping screw through holes. Screws are inserted through the self-tapping screw through holes and screw posts to achieve fastening, thereby assembling the lower bottom shell 11 onto the upper bottom shell 21.

[0047] Furthermore, the first mounting part 13 and the first clamping part 24 cooperate to form a bearing mounting space for mounting the bearing; the second mounting part 15 and the second clamping part 25 cooperate to form a motor mounting space for mounting the motor; wherein, the bearing is a bearing required to support the rotating shaft of the cross-flow fan blade 12, and the motor is a motor that drives the cross-flow fan blade 12 to rotate.

[0048] Preferably, in combination with the above schemes, such as Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, in one embodiment of the present invention, the first pressing part 24 and the second pressing part 25 are integrally formed on the upper bottom shell 21, which can reduce the number of parts while ensuring installation strength and is beneficial to the setting of the rotating mechanism.

[0049] Preferably, in combination with the above schemes, such as Figure 2 and Figure 5 As shown, in one embodiment of the present invention, the lower bottom shell assembly 1 further includes a lower spoiler 17, which is mounted on the lower bottom shell 11; the upper bottom shell assembly 2 further includes an upper spoiler 26, which is mounted on the upper bottom shell 21.

[0050] Specifically, the lower spoiler 17, bearing 14, motor 16, and cross-flow fan blade 12 are pre-assembled onto the lower bottom shell 11 in sequence, and the rotating volute 22 and upper spoiler 26 are pre-assembled onto the upper bottom shell 21 in sequence, ensuring a smooth and unobstructed assembly process. Finally, through the cooperation of the first clamping part 24 and the first mounting part 13, and the cooperation of the second clamping part 25 and the second mounting part 15, the upper bottom shell assembly 2 can be assembled onto the lower bottom shell assembly 1. The assembly scheme is simple, reasonable, and easy to operate.

[0051] Preferably, in combination with the above schemes, such as Figure 4 , Figure 7 and Figure 8As shown in the figure, in one embodiment of the present invention, the rotating mechanism includes two first rotating components disposed at both ends of the side wall 23 of the upper bottom shell. The first rotating components are used to drive the rotating volute 22 to rotate. Specifically, when the first rotating components drive the rotating volute 22 to rotate to the first position, the air conditioner bottom shell assembly is adapted to the air outlet mode of upper air outlet and lower air inlet; when the first rotating components drive the rotating volute 22 to rotate to the second position, the air conditioner bottom shell assembly is adapted to the air outlet mode of lower air outlet and upper air inlet, thereby realizing the upper and lower air outlet of the single cross-flow air conditioner indoor unit by changing the position of the rotating volute 22.

[0052] Preferably, in combination with the above schemes, such as Figure 7 and Figure 8 As shown, in one embodiment of this utility model, the first rotating component adopts a classic crank-slider mechanism, which is simple in structure and easy to manufacture. The first rotating component includes a crank 31 and a first protruding shaft 33. The upper bottom shell assembly 2 is also provided with a stepper motor as the driving component. One end of the crank 31 is connected to the output end of the stepper motor, so that the crank 31 is directly driven by the stepper motor and rotates at a constant angular velocity. The other end of the crank 31 is provided with a stroke groove 32. The first protruding shaft 33 is provided on the side wall of the rotating volute 22. The side wall 23 of the upper bottom shell is provided with a first sliding groove 34. The crank 31 is fitted against the side wall 23 of the upper bottom shell, and the first protruding shaft 33 can slide freely through the stroke groove 32 and the first sliding groove 34.

[0053] Specifically, the length direction of the stroke groove 32 is consistent with the length direction of the crank 31, and the first slide groove 34 has an arc-shaped structure. From the starting end to the ending end of the first slide groove 34, the distance between the axis of the first slide groove 34 and the axis of the cross-flow fan blade 12 gradually increases. Thus, when the crank 31 rotates with the stepper motor, the first protruding shaft 33 moves along the stroke groove 32 and the first slide groove 34, and drives the rotating volute 22 to rotate.

[0054] Preferably, in combination with the above schemes, such as Figure 7 and Figure 8 As shown, in one embodiment of the present invention, the rotating mechanism further includes two second rotating components disposed at both ends of the side wall 23 of the upper bottom shell. The second rotating components are used to limit the rotation of the rotating volute 22.

[0055] Preferably, in combination with the above schemes, such as Figure 7 and Figure 8As shown in the figure, in one embodiment of the present invention, the second rotating assembly includes a second protruding shaft 35, which is disposed on the rotating volute 22. A second sliding groove 36 is also provided on the side wall 23 of the upper bottom shell, and the second protruding shaft 35 can slide through the second sliding groove 36. Specifically, when the crank 31 rotates between the upper air outlet limit position and the lower air outlet limit position under the drive of the stepper motor, the second rotating assembly can limit the rotation of the rotating volute 22 to the direction along the second sliding groove 36, making the rotational movement of the rotating volute more stable.

[0056] Specifically, the second slide groove 36 has an arc-shaped structure; from the starting end to the ending end of the second slide groove 36, the distance between the axis of the second slide groove 36 and the axis of the cross-flow fan blade 12 gradually increases; thus, when the rotating volute 22 rotates, the second protruding shaft 35 moves along the second slide groove 36, which plays a limiting role on the rotating volute; preferably, the structure of the second slide groove 36 is the same as the structure of the first slide groove 34.

[0057] Preferably, in combination with the above schemes, such as Figure 9 and Figure 10 As shown in the figure, in one embodiment of this utility model, the indoor unit of the air conditioner adopts an inverted V-shaped heat exchanger. In this case, the lower shell 11 has a lower shell water collection tray 41, which is used to support the heat exchanger on one side of the lower shell 11 and collect the condensate generated by the heat exchanger. A drain outlet 42 is provided on the lower shell water collection tray 41 for draining the condensate collected by the lower shell water collection tray 41.

[0058] In some possible embodiments, the bottom casing water receiving tray 41 is arranged in an inclined direction, and the drain outlet 42 is located at the lower end of the bottom casing water receiving tray 41. Preferably, the drain outlet 42 is located at the lowest point of the bottom casing water receiving tray 41, so that condensate can flow into the drain outlet 42 along the inclined direction of the bottom casing water receiving tray 41 and be smoothly discharged to the outside.

[0059] Preferably, in combination with the above schemes, such as Figure 3 , Figure 9 and Figure 10 As shown in the figure, in one embodiment of this utility model, when the indoor unit of the air conditioner uses an inverted V-shaped heat exchanger, the upper bottom shell 21 has an upper bottom shell water collection tray 43, which is used to support the heat exchanger on one side of the upper bottom shell 21 and collect the condensate generated by the heat exchanger. When the upper bottom shell 21 is connected to the lower bottom shell 11, the upper bottom shell water collection tray 43 is connected to the lower bottom shell water collection tray 41, so that the condensate collected by the upper bottom shell water collection tray 43 can flow into the lower bottom shell water collection tray 41 and be discharged to the outside through the drain outlet 42.

[0060] In some possible embodiments, the upper bottom shell water receiving tray 43 and the lower bottom shell water receiving tray 41 are arranged in the same inclined direction, so that the condensate water can flow into the lower bottom shell water receiving tray 41 along the inclined direction of the upper bottom shell water receiving tray 43.

[0061] Preferably, in combination with the above schemes, such as Figure 3 , Figure 9 and Figure 10 As shown in the figure, in one embodiment of the present invention, the lower bottom shell water receiving tray 41 has a connecting interface 44, and the upper bottom shell water receiving tray 43 has a drainage channel 45. The drainage channel 45 is adapted to communicate with the connecting interface 44, so that the upper bottom shell water receiving tray 43 communicates with the lower bottom shell water receiving tray 41, thereby allowing the condensate collected in the upper bottom shell water receiving tray 43 to flow into the lower bottom shell water receiving tray 41 through the drainage channel 45 and the connecting interface 44. The connecting interface 44 and the drainage channel 45 are located at one end of the drain outlet 42, so that the condensate collected in the upper bottom shell water receiving tray 43, after flowing into the lower bottom shell water receiving tray 41, can be discharged to the outside through the drain outlet 42.

[0062] Accordingly, in conjunction with the above solutions, this utility model also provides an air conditioner indoor unit, which includes a reversible air-discharge bottom shell assembly as provided in the first aspect embodiment. By splitting the bottom shell assembly into an upper bottom shell assembly 2 and a lower bottom shell assembly 1, the lower bottom shell assembly 1 is pre-installed with parts such as a cross-flow fan blade 12 and a lower spoiler 17, and the upper bottom shell assembly 2 is pre-installed with parts such as a rotating volute 22 and an upper spoiler 26, thereby solving the problem of difficult assembly of parts such as the rotating volute 22 and spoiler in the air conditioner indoor unit.
