Description

Technical Field

[0001] This application relates to the field of air conditioner technology, and more specifically, to a wall-mounted air conditioner and a reversible air outlet air conditioner. Background Technology

[0002] Traditional wall-mounted air conditioners use a single cross-flow fan blade and a single air outlet design, relying on the air guide plate to adjust the airflow direction, which results in limited air volume. At the same time, existing air guide plates have been partially cut out to avoid the filter screen track, causing problems such as air leakage and increased noise. Summary of the Invention

[0003] This application provides a wall-mounted air conditioner and a reversible air outlet air conditioner. When the wall-mounted unit performs its downward air outlet function, the bottom end of the overlapping air guide plate can pass through the longitudinal channel groove formed between the ends of the first and second tracks without interference, forming a continuous overlap with the lower air guide plate. This structure eliminates the local gaps caused by the tracks encroaching on the air guide plate in traditional solutions, maintaining the geometric continuity of the air duct cavity, thereby suppressing eddy current and secondary flow losses, and significantly reducing the airflow attenuation rate. Specifically:

[0004] The first aspect of this application provides a wall-mounted air conditioner unit, applied to an air conditioner with reversible airflow from top to bottom, including:

[0005] The air conditioner housing has an upper air vent at the top and a lower air vent at the bottom, and an air duct connecting the upper and lower air vents is formed inside the air conditioner housing.

[0006] The air guide plate assembly includes an overlapping air guide plate disposed between the bottom side of the air duct and the lower air outlet, wherein when the wall-mounted unit takes in air at the upper air outlet and takes out air at the lower air outlet, the overlapping air guide plate can be connected to the air duct wall.

[0007] The filter assembly includes a filter track, which includes a first track and a second track separated at the bottom of the air duct. A first filter is movably disposed in the first track, and a second filter is movably disposed in the second track. By controlling the movement position of the first filter in the first track and the movement position of the second filter in the second track, the airflow at the upwind end can be filtered and / or the airflow at the downwind end can be filtered.

[0008] The first and second tracks are spaced apart by a channel groove, and the bottom end of the overlapping air guide plate can pass through the channel groove when the overlapping air guide plate is connected to the air duct.

[0009] In the above technical solution, the air guide plate assembly also includes a lower air guide plate disposed at the downwind outlet.

[0010] The overlapping air guide plate is controlled to be in the first position of overlapping the air duct wall and the lower air guide plate when the wall-mounted unit is inlet air and outlet air, and in the second position of separating the air duct wall and the lower air guide plate when the wall-mounted unit is inlet air and outlet air; or the overlapping air guide plate is always in the first position of overlapping with the lower air guide plate.

[0011] The first track is a horizontally extending track set at the bottom of the wall-mounted unit and corresponding to part of the downdraft opening. The rear end of the first track corresponds to the rear edge of the downdraft opening, and the front end extends to the front edge of the downdraft opening. Part of the second track extends horizontally and corresponds to another part of the downdraft opening, and the rest extends upward along the front edge and top edge of the wall-mounted unit to the rear edge of the updraft opening.

[0012] A channel groove extending vertically is formed between the front end of the first track and the lower end of the second track. The bottom opening of the channel groove corresponds to the top of the lower air guide plate. When the air guide plate is in the first position, the bottom end of the air guide plate can pass through the channel groove and overlap with the lower air guide plate.

[0013] In the above technical solution, when the air outlet mode of the wall-mounted unit is top air intake and bottom air outlet, the first filter moves to a position to avoid the downwind vent, and the second filter moves to a position to avoid the downwind vent and correspond to the upper filter position of the upwind vent, so that the airflow entering from the upwind vent can be filtered through the second filter.

[0014] When the air outlet mode of the wall-mounted unit is set to bottom air intake and top air outlet, the first filter moves to the corresponding bottom air outlet and the second filter moves to the corresponding bottom air outlet, avoiding the bottom air outlet, so that the airflow entering from the bottom air outlet can be filtered through the first and second filters.

[0015] In the above technical solution, the front end of the first track and the lower end of the second track are at the same height.

[0016] The wall-mounted air conditioner unit mentioned above also includes:

[0017] The first drive mechanism includes a first gear for driving the first filter screen to move, wherein the length of the first filter screen is configured such that when the first filter screen moves to the lower filter position corresponding to the downwind vent, at least a portion of it is still engaged with the first gear drive mechanism.

[0018] and / or

[0019] The second drive mechanism includes a second gear for driving the movement of the second filter screen, wherein the length of the second filter screen is configured such that when the second filter screen moves to the filtration position corresponding to the downwind or upwind vent, at least a portion of it remains engaged with the second gear drive mechanism.

[0020] The wall-mounted air conditioner unit mentioned above also includes:

[0021] A first cleaning component includes a first cleaning brush disposed on the moving path of a first filter screen for cleaning the moving first filter screen.

[0022] and / or

[0023] The second cleaning component includes a second cleaning brush disposed on the movement path of the second filter screen for cleaning the second filter screen during movement.

[0024] In the above technical solution, the overlapping air guide plate is configured as an arc-shaped air guide plate or a straight air guide plate;

[0025] When the overlapping air guide plate is in the first position, the upper and lower ends of the overlapping air guide plate overlap with the bottom end of the air duct wall and the top end of the lower air guide plate, respectively.

[0026] In the above technical solution, there are multiple lower air guide plates, including a front air guide plate near the front edge of the downdraft opening, a rear air guide plate near the rear edge of the downdraft opening, and at least one intermediate air guide plate between the front air guide plate and the rear air guide plate.

[0027] The bottom opening of the channel slot corresponds to the top position of the middle air guide plate.

[0028] The wall-mounted air conditioner unit mentioned above also includes:

[0029] The movable volute and the spoiler are arranged opposite each other on the front and rear sides of the cross-flow fan blade. The movable volute is movable up and down on the front side of the cross-flow fan blade, and the spoiler is movable back and forth on the rear side of the cross-flow fan blade.

[0030] The movable volute, spoiler, and overlapping air deflector are configured as follows:

[0031] When the air outlet mode of the wall-mounted unit is top air intake and bottom air outlet, the movable volute moves downward to the lower working position, the spoiler swings forward to at least partially protrude from the rear air guide wall of the air conditioning duct, and the overlapping air guide plate moves to the first position. In the first position, the top end of the overlapping air guide plate overlaps with the bottom end of the movable volute, and the bottom end overlaps with the top end of the lower air guide plate. The overlapping air guide plate, the movable volute, and the lower air guide plate together constitute the front air guide wall of the air duct.

[0032] When the air outlet mode of the wall-mounted unit is bottom air intake and top air outlet, the movable volute moves upward to the upper working position to form the front guide wall of the air duct, the spoiler swings backward to abut against the rear guide wall of the air duct, and the overlapping guide plate moves to the second position. In the second position, the top gap of the overlapping guide plate is at the bottom end of the movable volute, and the bottom gap is at the top end of the lower guide plate.

[0033] The second aspect of this application provides a reversible air outlet air conditioner, which includes an outdoor unit of the air conditioner and a wall-mounted air conditioner provided in the first aspect of this application.

[0034] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0035] In this embodiment, when the wall-mounted air conditioner performs its downward air outlet function, the bottom end of the overlapping air guide plate can pass through the longitudinal channel groove formed between the ends of the first and second tracks without interference, and form a continuous overlap with the lower air guide plate. This structure eliminates the local gaps caused by the tracks encroaching on the air guide plate in traditional solutions, maintaining the geometric continuity of the air duct cavity, thereby suppressing eddy current and secondary flow losses, and significantly reducing the air volume attenuation rate.

[0062] Before describing the solution in this application, refer to the prior art. Figure 1 ,exist Figure 1 In order for an air conditioner to vent air both above and below, the filter must move along with the air duct. However, when the filter moves, the air guide plate must make way for it—that is, a notch must be cut at the bottom of the air guide plate. Once the notch is opened, air will leak out from the notch, the air volume will shrink instantly, the noise will increase accordingly, and the cooling or heating effect will be affected.

[0063] Based on this, such as Figures 1-6 As shown, the first aspect of this application provides a wall-mounted air conditioner, applied to a reversible air outlet air conditioner, comprising:

[0064] The air conditioner housing 10 has an upper air vent 101 at the top and a lower air vent 102 at the bottom. An air duct 103 is formed inside the air conditioner housing 10, which connects the upper air vent 101 and the lower air vent 102.

[0065] The air guide plate assembly includes an overlapping air guide plate 50 disposed between the bottom side of the air duct and the lower air outlet 102, wherein when the wall-mounted unit receives air at the upper air outlet 101 and expels air at the lower air outlet 102, the overlapping air guide plate 50 can be connected to the air duct wall of the air duct 103.

[0066] The filter assembly includes a filter track, which includes a first track 701 and a second track 702 separated at the bottom of the air duct 103. A first filter 601 is movably disposed in the first track 701, and a second filter 602 is movably disposed in the second track 702. By controlling the movement position of the first filter in the first track and the movement position of the second filter in the second track, the airflow at the upwind outlet and / or the airflow at the downwind outlet can be filtered.

[0067] The first and second tracks are spaced apart by a channel groove, and the bottom end of the overlapping air guide plate can pass through the channel groove when the overlapping air guide plate is connected to the air duct.

[0068] Furthermore, in some possible implementations, the air guide plate assembly also includes a lower air guide plate 40 disposed at the downwind outlet 102;

[0069] The overlapping air guide plate 50 is controlled to be in the first position overlapping the air duct wall and the lower air guide plate 40 when the wall-mounted unit is inlet air and outlet air, and in the second position separating the air duct wall and the lower air guide plate 40 when the wall-mounted unit is inlet air and outlet air; or the overlapping air guide plate 50 is always in the first position overlapping with the lower air guide plate 40; that is, the overlapping air guide plate 50 in this embodiment can be either movable or fixed.

[0070] The first track 701 is a horizontally extending track installed at the bottom of the wall-mounted unit and corresponding to part of the downvent 102. The rear end of the first track 701 corresponds to the rear edge of the downvent 102, and the front end extends to the front edge of the downvent 102. A part of the second track 702 extends horizontally and corresponds to another part of the downvent 102, and the rest extends upward along the front edge and top edge of the wall-mounted unit to the rear edge of the upvent 101.

[0071] A channel groove extending vertically is formed between the front end of the first track 701 and the lower end of the second track 702. The bottom opening of the channel groove corresponds to the top of the lower air guide plate 40. When the overlapping air guide plate 50 is in the first position, the bottom end of the overlapping air guide plate 50 can pass through the channel groove and overlap with the lower air guide plate 40.

[0072] In this embodiment, two filter tracks are set, with their ends positioned relative to each other on the moving path of the overlapping air guide plate 50. The gap between the ends of the two filter tracks forms a "channel groove" suitable for the movement of the overlapping air guide plate 50. Taking the movable configuration of the overlapping air guide plate 50 as an example, when the air conditioner needs to blow air downwards, the overlapping air guide plate 50 can pass through the pre-reserved channel groove between the first and second tracks, like a drawer partition, and completely overlap the lower air guide plate 40. When the air conditioner needs to blow air upwards, the overlapping air guide plate 50 can cleanly and neatly return to its separated position. In this way, airflow loss is minimized, and noise is eliminated by the "air leakage" amplifier, thereby improving the reversible airflow effect of the wall-mounted unit.

[0073] Furthermore, in some possible implementations, when the air outlet mode of the wall-mounted unit is top air intake and bottom air outlet, the first filter 601 moves to a position to avoid the downwind vent 102, and the second filter 602 moves to a position to avoid the downwind vent 102 and correspond to the upper filter position of the upwind vent, so that the airflow entering from the upwind vent 101 can be filtered through the second filter 602.

[0074] When the air outlet mode of the wall-mounted unit is bottom air intake and top air outlet, the first filter 601 moves to the corresponding bottom air outlet 102 and the second filter 602 moves to the corresponding bottom air outlet 102, avoiding the bottom air outlet 101, so that the airflow entering from the bottom air outlet 102 can be filtered through the first filter 601 and the second filter 602.

[0075] In the wall-mounted air conditioner of this embodiment, in the top-intake-bottom-outtake mode, the second filter 602 moves upward along the second track 502 to the "upper filtration position" aligned with the rear edge 101a of the upper air vent 101; simultaneously, the first filter 601 moves backward along the first track 501, completely leaving the effective flow section of the lower air vent 102. Thus, all airflow entering the duct is filtered only by the second filter 602, with the filtration area corresponding to the opening area of ​​the upper air vent 101 in a 1:1 ratio, eliminating the additional resistance caused by redundant filter coverage. In the bottom-intake-top-outtake mode, the first filter 601 moves forward and covers the rear area of ​​the lower air vent 102, while the second filter 602 descends along the second track 502 to the "bottom filtration position" aligned with the front area of ​​the lower air vent 102; the two filters form a continuous filtration surface on both sides of the channel groove, ensuring that the entire air intake area of ​​the lower air vent 102 is double-filtered, maintaining a filtration efficiency of ≥99% even under high airflow conditions.

[0076] Furthermore, in some possible implementations, the front end of the first track 701 and the lower end of the second track 702 are at the same height.

[0077] In this embodiment, by setting the two ends of the two tracks to the same height with a height difference of 0, the opening of the channel groove in the width direction is rectangular. When the overlapping wind guide plate 401 passes through, a symmetrical slit sealing surface can be formed. Wind tunnel tests show that the vortex intensity at the groove opening is effectively reduced in this state, thereby reducing the additional noise caused by local turbulence.

[0078] Furthermore, in some possible implementations, the wall-mounted air conditioner also includes:

[0079] The first drive mechanism 801 includes a first gear for driving the first filter screen 601 to move, wherein the length of the first filter screen 601 is configured such that when the first filter screen 601 moves to the lower filter position corresponding to the downflow vent 102, at least a portion of it is still engaged with the first gear.

[0080] and / or

[0081] The second drive mechanism 802 includes a second gear for driving the movement of the second filter screen 602, wherein the length of the second filter screen 602 is configured such that when the second filter screen 602 moves to the filtration position corresponding to the downwind vent 102 or upwind vent 101, at least a portion of it is still engaged with the second gear.

[0082] In this embodiment, regardless of whether the first filter 601 is in the fully avoidance position or the lower filter position, its rack section always remains engaged with the first gear; similarly, the second filter 602 is always engaged with the second gear throughout its entire stroke. This eliminates the risk of "empty stroke" or tooth disengagement, and the filter positioning accuracy can be stably maintained within ±0.3mm. During operation, the filter vibration amplitude is reduced to 0.1mm, avoiding jamming or noise spikes caused by engagement failure.

[0083] Furthermore, in some possible implementations, the wall-mounted air conditioner also includes:

[0084] A first cleaning component 901 includes a first cleaning brush disposed on the moving path of a first filter 601 for cleaning the moving first filter.

[0085] and / or

[0086] The second cleaning component includes a second cleaning brush disposed on the movement path of the second filter screen for cleaning the second filter screen during movement.

[0087] In this embodiment, the cleaning brush maintains constant line contact with the filter surface; when the filter moves back and forth in the track, the brush body immediately peels off the attached fibers and dust, so that the resistance increment of the filter after a single cycle is significantly reduced, effectively delaying the performance degradation caused by dust accumulation.

[0088] Furthermore, in some possible implementations, the overlapping air guide plate is configured as an arc-shaped air guide plate or a straight air guide plate.

[0089] When the overlapping air guide plate is in the first position, the upper and lower ends of the overlapping air guide plate overlap with the bottom end of the air duct wall and the top end of the lower air guide plate, respectively.

[0090] In this embodiment, when the overlapping air guide plate 401 is arc-shaped, its curvature transitions continuously with the profile of the air duct wall, which can delay the boundary layer separation point and significantly improve the uniformity of air outlet under actual measurement in the air outlet mode; if a straight shape is adopted, the same sealing performance can be achieved by increasing the overlap length, which is suitable for models with limited volute space and maintains aerodynamic efficiency loss of <1%.

[0091] Furthermore, in some possible embodiments, the lower air guide plate 40 is provided in multiple ways, including a front air guide plate near the front edge of the downdraft outlet 102, a rear air guide plate near the rear edge of the downdraft outlet 102, and at least one intermediate air guide plate between the front air guide plate and the rear air guide plate.

[0092] The bottom opening of the channel slot corresponds to the top position of the middle air guide plate.

[0093] In this embodiment, the channel slot is configured to align only with the middle air guide plate 40c. This reduces the area of ​​the lower air outlet when the wall-mounted unit is inlet air and outlet air is outlet air, thereby increasing the outlet air speed. This allows the airflow from the lower air outlet to have sufficient flow momentum to flow downward along the wall, thus achieving carpet-like heating.

[0094] Furthermore, in some possible implementations, the wall-mounted air conditioner also includes:

[0095] The movable volute 1002 and the spoiler 1001 are respectively arranged on the front and rear sides of the cross-flow fan blade 20. The movable volute 1002 is arranged on the front side of the cross-flow fan blade 20 and can be moved up and down. The spoiler 1001 is arranged on the rear side of the cross-flow fan blade 20 and can be swung back and forth.

[0096] The movable volute 1002, spoiler 1001, and overlapping air guide 50 are configured as follows:

[0097] When the air outlet mode of the wall-mounted unit is top air intake and bottom air outlet, the movable volute 1002 moves downward to the lower working position, the spoiler 1001 swings forward to at least partially protrude from the rear air guide wall of the air conditioning duct, and the overlapping air guide plate 50 moves to the first position. In the first position, the top end of the overlapping air guide plate 50 overlaps with the bottom end of the movable volute 1002, and the bottom end overlaps with the top end of the lower air guide plate 40. The overlapping air guide plate 50, the movable volute 1002, and the lower air guide plate 40 together constitute the front air guide wall of the air duct 103.

[0098] When the air outlet mode of the wall-mounted unit is bottom air intake and top air outlet, the movable volute 1002 moves upward to the upper working position to form the front guide wall of the air duct 103, the spoiler 1001 swings backward to abut against the rear guide wall of the air duct 103, and the overlapping guide plate 50 moves to the second position. In the second position, the top gap of the overlapping guide plate is at the bottom end of the movable volute 1002, and the bottom gap is at the top end of the lower guide plate 40.

[0099] To better understand the wall-mounted unit in the embodiments of this application, the following is combined with... Figures 1-6 A detailed explanation follows:

[0100] Specifically, in the top-discharge mode: For cooling or ventilation modes, because hot air rises, the hot air from the top-discharge mode cannot descend, severely impacting comfort. Top-discharge cooling easily achieves shower-like cooling, with cool air not blowing directly on people. In this mode, the spoiler 1001 is initially positioned smoothly connected to the rear air duct wall. The movable volute 1002 moves upward and overlaps with the upper teardrop-shaped upper limit structure 1006. The overlapping air guide plate 50 rotates to a second position, separating from the front air duct wall and the lower air guide plate. The first filter 601 and the second filter 602 move to the lower air outlet 102. It should be noted that top-discharge cooling easily achieves shower-like cooling, with cool air not blowing directly on people, and low noise, making it suitable for quieter environments, such as sleeping areas.

[0101] Specifically, in the bottom air outlet mode: for heating or ventilation modes, hot air is delivered from the bottom to achieve carpet-like heating. In this mode, the spoiler 1011 is located in the open position protruding from the rear air duct wall, the overlapping air guide plate 50 rotates to the first position overlapping with the front air duct wall and the lower air guide plate, the bottom end of the movable volute tongue 1002 overlaps with the top end of the lower air guide plate, the second filter 602 moves to the upper air outlet position, and the first filter 601 moves to the position avoiding the lower air outlet. In this way, indoor air is blown out through the lower air outlet after heat exchange through the evaporator from the top.

[0102] As can be seen, this application achieves airflow filtration during reversible air supply through the coordinated movement of different filters. Regarding the installation of the filters, such as... Figures 4-6 As shown, the second filter screen can be inserted from the filter screen assembly inlet 1005 of the panel body into the filter screen track. The length overlap section is limited by the tracks on the left and right sides of the panel body. Then, the filter screen pressure plate 1004 is assembled onto the panel body to press down the second filter screen, and the filter screen pressure plate and the panel body together form a complete track. For disassembling the second filter screen, after setting the second filter screen to run to the upper air vent, the power is turned off, the filter screen pressure plate 1004 is opened, and the filter screen length overlap section is pulled out. The purpose of the filter screen length overlap section is twofold: firstly, to facilitate installation and disassembly; and secondly, to ensure that the panel body and the filter screen pressure plate are properly aligned with the track, preventing the filter screen from becoming dislodged and failing. That is, the filter screen runs across the splicing position of the two parts, making it less prone to deformation and jamming. It should be noted that the length overlap section of the second filter screen 602 refers to the filter screen segment located below the drive gear when the upper end of the second filter screen 602 runs to a position opposite to the rear edge of the upper air vent 101. Figure 2 As shown, the length of the second filter screen located on the lower side of the second drive mechanism 802 is the aforementioned filter screen overlap section.

[0103] Next, we will focus on introducing the operation control mode of the filter screen:

[0104] The indoor wall-mounted unit checks if the second filter is clogged. If not, the second filter is located at the downwind vent and does not need to be moved; the indoor unit operates normally. If it is, it further checks if both the left and right second filters are at the downwind vent. (It should be noted that, viewed from the front of the air conditioner, conventional air conditioners have two filters, one on the left and one on the right. In this embodiment, there can be four filters, i.e., two on the left and two on the right for the first and second filters.) If so, the second filters on both sides move to the upwind vent, the indoor unit stops operating, the filter pressure plate is removed, and the second filter is taken out for cleaning. If not, if both second filters are at the upwind vent, the second filters do not move, the indoor unit is turned off, and the second filters are cleaned. If one side of the second filter is at the upwind vent, the other side's second filter must first move to the upwind vent before both second filters are removed and cleaned. After cleaning, the user installs the second filter. Further checks are needed to ensure the second filter is properly installed. If not, the second filter will first move to the upwind position, stop after contacting the microswitch, and then move to the downwind position (the initial and default position of the second filter). If it is installed correctly, the second filter will move to the downwind position, and the system will continue to check for dirt or blockage in the first filter. If blockage is present, the first filter will automatically retract and self-clean itself using a brush. If no blockage is present, the brush will not rotate, the first filter does not require cleaning, and the indoor unit will operate normally.
