Description

Technical Field

[0001] This utility model belongs to the field of air conditioning technology, specifically relating to a reversible air supply air conditioner. Background Technology

[0002] Existing floor-standing air conditioners use a filter at the air inlet to prevent dust from being drawn into the evaporator or the interior of the unit. However, over time, dust accumulates on the filter, obstructing airflow and reducing the amount of air output. This decreases the air conditioner's cooling and heating efficiency and negatively impacts indoor air quality.

[0003] While the filter of a standard unidirectional air conditioner can be removed for cleaning, reversible air conditioners have their vents at the top and bottom, and lack an air intake grille at the rear, making it impossible to install a filter using existing technology. Without a filter, prolonged operation will lead to internal dirt buildup in the air conditioner casing and unpleasant odors in the exhaust.

[0004] Therefore, when adding filter devices to the upper and lower air vents of a reversible air supply air conditioner, the ease of disassembling and cleaning the filter devices needs to be considered. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of the aforementioned technologies by proposing a reversible air supply air conditioner. This invention aims to solve the problems of dirt and dust accumulation in the indoor heat exchanger caused by the inability to add a filter to the rear of existing reversible air supply air conditioners, thereby achieving airflow purification.

[0006] This utility model provides a reversible air-supply air conditioner, including a housing, a fan, an indoor heat exchanger, and a filter assembly. The housing has an upper air outlet at the top and a lower air outlet at the bottom. The fan is disposed between the upper and lower air outlets. The indoor heat exchanger is disposed between the fan and the upper air outlet. The filter assembly is disposed on an upper air duct between the upper air outlet and the indoor heat exchanger. The filter assembly can rotate between a first position and a second position. When the upper air outlet is used as an air outlet, the filter assembly rotates to the first position and abuts against the inner wall of the housing to prevent airflow in the upper air duct from flowing out of the air outlet. When the upper air outlet is used as an air inlet, the filter assembly rotates to the second position and completely covers the windward surface of the indoor heat exchanger to filter the airflow entering the upper air duct from the upper air outlet.

[0007] Furthermore, the filter assembly includes a filter mounting bracket, a filter, and a top cover assembly; the filter mounting bracket has an inner cavity for receiving the filter, which can be slidably installed in the cavity; the top cover assembly can be pulled out and installed on the top of the housing, and the top of the top cover assembly is provided with a handle and the bottom is detachably connected to the filter.

[0008] Furthermore, it also includes a drive assembly for driving the filter assembly to rotate between a first position and a second position.

[0009] Furthermore, the drive assembly includes a drive mounting bracket, an arc-shaped guide rail, and a drive motor; the drive mounting bracket is disposed on the inner wall of the upper air duct, and the arc-shaped guide rail is connected to the top of the drive mounting bracket; a first rotating shaft hole is opened at the bottom of the drive mounting bracket, and guide posts that cooperate with the arc-shaped guide rail are provided on both sides of the top of the filter mounting bracket, and a first rotating shaft that cooperates with the first rotating shaft hole is provided on both sides of the bottom; the drive motor is connected to the first rotating shaft, and when the drive motor drives the first rotating shaft to rotate, the guide posts slide along the arc-shaped guide rail, thereby driving the filter assembly to switch between a first position and a second position.

[0010] Furthermore, the top cover assembly includes a top cover body and a plurality of hooks disposed at the bottom of the top cover body; the top of the filter screen extends upward and has an extension portion, on which a mating hole is provided to engage with the hooks.

[0011] Furthermore, the upper cover assembly also includes a clamping block; the upper cover body has an installation groove, and the inner wall of the installation groove has coaxially arranged second rotating shaft holes on both sides; the clamping block has second rotating shafts on both sides that cooperate with the second rotating shaft holes, and the bottom of the clamping block has a protrusion, which can lock and / or unlock the protrusion when the clamping block rotates.

[0012] Furthermore, the protrusion has a forward-extending pressing part and a buckle perpendicular to the pressing part; the hook is provided with a spring buckle that engages with the buckle; the pressing block is configured such that when the pressing block is rotated to the locked state, the buckle engages with the spring buckle and the pressing part abuts against the surface of the protrusion; when the pressing block is rotated to the unlocked state, the buckle disengages from the spring buckle and the filter screen can be removed from the top cover assembly.

[0013] Furthermore, the reversible air supply air conditioner also includes a dust removal component, which includes a dust collection box and a roller brush. The dust collection box is located at the bottom of the receiving cavity, and has an opening on the side facing the filter screen. The roller brush is rotatably disposed inside the dust collection box, and its outer surface contacts the filter screen. When the filter screen slides up and down in the receiving cavity, the roller brush rotates in the opposite direction to the sliding direction of the filter screen, sweeping the dust on the filter screen into the dust collection box.

[0014] Furthermore, the reversible air-supply air conditioner also includes an air quality sensor and a controller. The air quality sensor is disposed inside the housing and is used to detect the concentration of at least one air pollutant. The controller is electrically connected to the air quality sensor and the drive motor. The controller is configured to control the drive motor to rotate the filter assembly to a second position when the air quality sensor detects that the concentration of the air pollutant is greater than or equal to a preset threshold.

[0015] Furthermore, the housing also includes a downdraft duct disposed between the downdraft outlet and the indoor heat exchanger, and a filter assembly is also disposed on the downdraft duct; the filter assembly located on the updraft duct and the filter assembly located on the downdraft duct are independently controlled; wherein, when the updraft outlet is used as an air outlet, the filter assembly located on the updraft duct rotates to a first position and the filter assembly located on the downdraft duct rotates to a second position; when the updraft outlet is used as an air inlet, the filter assembly located on the updraft duct rotates to the second position and the filter assembly located on the downdraft duct rotates to the first position.

[0053] like Figures 1 to 5 As shown, this utility model embodiment provides a reversible air-supply air conditioner, including a housing 1, a fan 2, an indoor heat exchanger 3, and a filter assembly 4. Specifically, the housing 1 forms a closed space in the front-to-back direction and has an upper air inlet 11 at the top and a lower air inlet 12 at the bottom, allowing air to enter the housing 1 vertically. The fan 2 is disposed between the upper air inlet 11 and the lower air inlet 12 for drawing in air and blowing out air. The indoor heat exchanger 3 is disposed between the fan 2 and the upper air inlet 11. When the reversible air-supply air conditioner is in cooling mode, the lower air inlet 12 serves as the air inlet and the upper air inlet 11 serves as the air outlet; when the reversible air-supply air conditioner is in heating mode, the upper air inlet 11 serves as the air inlet and the lower air inlet 12 serves as the air outlet, thus improving the cooling and heating effects. The filter assembly 4 is disposed on the upper air duct 13 between the upper air inlet 11 and the indoor heat exchanger 3, and the filter assembly 4 can rotate between a first position and a second position.

[0054] Specifically, when the reversible air-conditioning unit receives a cooling command, the upper air outlet 11 functions as an air outlet, and the filter assembly 4 rotates to the first position, hidden inside the housing 1 and away from the indoor heat exchanger 3. At this time, the filter assembly 4 is close to the inner wall of the housing 1 to prevent the airflow in the upper air duct 13 from flowing out of the air outlet, thus avoiding obstruction of the airflow and ensuring smooth airflow. When the reversible air-conditioning unit receives a heating command, the upper air outlet 11 functions as an air inlet, and the filter assembly 4 rotates to the second position. The filter assembly 4 completely covers the windward surface of the indoor heat exchanger 3 to filter the airflow entering the upper air duct 13 from the upper air outlet 11, thereby protecting the evaporator from contamination by airborne particles.

[0055] This utility model provides a reversible air supply air conditioner, which provides a rotatable filter assembly 4 on the upper air duct 13. When air is discharged from the upper air outlet 11, the filter assembly 4 rotates to the first position to ensure smooth and unobstructed airflow. When air is received from the upper air outlet 11, the filter assembly 4 rotates to the second position to filter the air. This solves the problem of dirt and dust blowing on the indoor heat exchanger 3 caused by the inability to add a filter 42 to the rear of the existing reversible air supply air conditioner, and achieves concealed airflow purification.

[0056] Preferably, in combination with the above schemes, such as Figures 6 to 11 As shown in the figure, as an embodiment of the present invention, the filter assembly 4 includes a filter mounting bracket 41, a filter 42, and a top cover assembly 43. A receiving cavity 411 is formed on the inner side of the filter mounting bracket 41, and the filter 42 can be slidably disposed within the receiving cavity 411, facilitating the installation or removal of the filter 42 from the mounting bracket. The top cover assembly 43 is retractable and mounted on the top of the housing 1, serving to cover the edge of the air vent 11. The top of the top cover assembly 43 is provided with a handle 44, and the bottom is detachably connected to the filter 42, allowing the filter 42 to be removed by lifting the top cover assembly 43 for easy cleaning or replacement.

[0057] Preferably, in combination with the above schemes, such as Figures 3 to 11 As shown, as an embodiment of the present invention, the reversible air supply air conditioner also includes a drive assembly, which is used to drive the filter assembly 4 to rotate between a first position and a second position.

[0058] Preferably, in combination with the above schemes, such as Figures 3 to 11 As shown in the figure, in one embodiment of this utility model, the drive assembly includes a drive mounting bracket, an arc-shaped guide rail 51, and a drive motor 52. The drive mounting bracket is disposed on the inner wall of the upper air duct 13, and the arc-shaped guide rail 51 is connected to the top of the drive mounting bracket to limit the rotation of the filter assembly 4. A first rotating shaft hole is provided at the bottom of the drive mounting bracket, and guide posts 412 that cooperate with the arc-shaped guide rail 51 are provided on both sides of the top of the filter mounting bracket 41, and first rotating shafts 413 that cooperate with the first rotating shaft hole are provided on both sides of the bottom. Specifically, when the first rotating shaft 413 rotates, the guide posts 412 can slide within the limiting range of the arc-shaped guide rail 51, thereby driving the filter assembly 4 to switch between a first position and a second position. The drive motor 52 is connected to the first rotating shaft 413 and is used to drive the rotation of the first rotating shaft 413.

[0059] Preferably, in combination with the above schemes, such as Figures 12 to 14As shown in the figure, in one embodiment of the present invention, the top cover assembly 43 includes a top cover body 431 and a plurality of hooks 432 disposed at the bottom of the top cover body 431. The top of the filter screen 42 extends upwards with a protrusion 421, and the protrusion 421 has a mating hole 422 that engages with the hooks 432. Specifically, when the hooks 432 of the top cover assembly 43 are connected to the mating holes 422 of the filter screen 42, the filter screen 42 is located directly below the handle 44, and the filter screen 42 can be smoothly pulled out by lifting the handle 44 upwards.

[0060] Preferably, in combination with the above schemes, such as Figures 15 to 24 As shown in the figure, as an embodiment of the present invention, the upper cover assembly 43 further includes a clamping block 433. The upper cover body 431 has a mounting groove, and the inner wall of the mounting groove has coaxially arranged second rotating shaft holes on both sides. The clamping block 433 has second rotating shafts 4331 on both sides that cooperate with the second rotating shaft holes, allowing the clamping block 433 to rotate within the mounting groove. The bottom of the clamping block 433 has a protrusion 4332. When the clamping block 433 rotates so that the protrusion 4332 abuts against the extension 421, the extension 421 is locked, thereby fixing the filter screen 42 below the upper cover assembly 43. When the clamping block 433 rotates so that the protrusion 4332 moves away from the extension 421, the extension 421 is unlocked, allowing the filter screen 42 to be removed from the upper cover assembly 43, facilitating operation of the filter assembly 43 as a whole.

[0061] The clamping block 433 can be rotated manually or driven by a motor. When the clamping block 433 is rotated manually, it is also provided with a protrusion for easy gripping.

[0062] Preferably, in combination with the above schemes, such as Figures 18 to 21 As shown in one embodiment of this utility model, the protrusion 4332 has a forward-extending pressing part 4333 and a buckle 4334 perpendicular to the pressing part 4333. The hook 432 is provided with a spring buckle 4321 that cooperates with the buckle 4334. Specifically, the pressing block 433 is configured such that when the hook 432 enters the range of the mating hole 422, the pressing block 433 is rotated to the locked state. At this time, the buckle 4334 and the spring buckle 4321 are engaged, and the pressing part 4333 abuts against the surface of the protrusion 421, thereby restricting the movement of the protrusion 421 and fixing the filter screen 42 to the upper cover assembly 43. By lifting the handle 44 upward, the filter screen 42 can be pulled out from the top of the housing 1 under the action of the hook 432. Rotate the clamping block 433 to the unlocked state. At this time, the latch 4334 disengages from the spring latch 4321, and the mating hole 422 can be freely removed from the hook 432, so that the filter screen 42 can be removed from the top cover assembly 43.

[0063] Understandably, when the reversible air-conditioning unit is in operation, the clamping block 433 is in the unlocked state by default. When the reversible air-conditioning unit receives a cleaning command, the drive motor 52 starts, causing the filter assembly 4 to rotate to the second position. At this time, the clamping block 433 is rotated to the locked state, and the filter 42 can be removed from the filter mounting bracket 41 by lifting the top cover assembly 43, making it easy to clean and replace.

[0064] Preferably, in conjunction with the above solution, as an embodiment of this utility model, the reversible air-supply air conditioner further includes a dust removal component. The dust removal component includes a dust collection box and a roller brush. The dust collection box is disposed at the bottom of the receiving cavity 411, and has an opening on the side facing the filter screen 42. The roller brush is rotatably disposed inside the dust collection box, and its outer surface contacts the filter screen 42. Specifically, when the filter screen 42 slides up and down within the receiving cavity 411, the roller brush rotates in the opposite direction to the sliding direction of the filter screen 42, sweeping the dust on the filter screen 42 into the dust collection box, thereby cleaning the floating dust on the surface of the filter screen 42 and preventing the floating dust from spreading into the room during the disassembly of the filter screen 42.

[0065] Preferably, in conjunction with the above scheme, as an embodiment of this utility model, the reversible air-supply air conditioner further includes an air quality sensor and a controller. The air quality sensor is disposed inside the housing 1 and is used to detect the concentration of at least one air pollutant, such as dust and lint in the air. The controller is electrically connected to the air quality sensor and the drive motor 52. The controller is configured such that when the air quality sensor detects that the concentration of air pollutants is greater than or equal to a preset threshold, the controller controls the drive motor 52 to rotate the filter screen 42 assembly 4 to a second position, thereby preventing air pollutants from entering the reversible air-supply air conditioner and forming dirt accumulation at the indoor heat exchanger 3.

[0066] Preferably, in conjunction with the above scheme, as an embodiment of this utility model, the housing 1 further includes a lower air duct 14 disposed between the lower air outlet 12 and the indoor heat exchanger 3. A filter assembly 4 is also disposed on the lower air duct 14, which can filter the incoming air when the lower air outlet 12 is used as an air inlet. The filter assembly 4 located on the upper air duct 13 and the filter assembly 4 located on the lower air duct 14 are independently controlled, such that when the upper air outlet 11 is used as an air outlet, the filter assembly 4 located on the upper air duct 13 rotates to a first position to ensure smooth and unobstructed airflow; the filter assembly 4 located on the lower air duct 14 rotates to a second position to filter the air. When the upper air outlet 11 is used as an air inlet, the filter assembly 4 located on the upper air duct 13 rotates to a second position to filter the air; the filter assembly 4 located on the lower air duct 14 rotates to a first position to ensure smooth and unobstructed airflow.
