[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, as Figures 1-6 shown, the first aspect of the embodiment of the application provides an air conditioner wall hanging machine applied to an up-down reversible air conditioner, comprising:

[0064] The air conditioner shell 10 is provided with an upper air outlet 101 at the top and a lower air outlet 102 at the bottom, and the inside of the air conditioner shell 10 forms an air duct 103 communicating with the upper air outlet 101 and the lower air outlet 102;

[0065] The air deflector assembly includes a lap air deflector 50 arranged between the bottom side of the air duct and the lower air outlet 102, wherein when the wall hanging machine takes in air at the upper air outlet 101 and discharges air at the lower air outlet 102, the lap air deflector 50 can be connected together with the air duct wall of the air duct 103;

[0066] The filter assembly includes a filter screen track, and the filter screen track includes a first track 701 and a second track 702 separated at the bottom of the air duct 103, a first filter screen 601 is movably arranged in the first track 701, and a second filter screen 602 is movably arranged in the second track 702. By controlling the moving position of the first filter screen in the first track and the moving position of the second filter screen in the second track, the air flow at the upper air outlet can be filtered and / or the air flow at the lower air outlet can be filtered;

[0067] The interval position of the first track and the second track forms a channel groove, and when the lap air deflector is connected together with the air duct, the bottom end of the lap air deflector can pass through the channel groove.

[0068] Further, in some possible implementations, the air deflector assembly further includes a lower air deflector 40 arranged at the lower air outlet 102;

[0069] The lap air deflector 50 is controlled to be in a first position of connecting the air duct wall and the lower air deflector 40 when the wall hanging machine takes in air from above and discharges air from below, and is in a second position of separating the air duct wall and the lower air deflector 40 when the wall hanging machine takes in air from below and discharges air from above; or the lap air deflector 50 is always in the first position of connecting the lower air deflector 40; that is, the lap air deflector 50 in the embodiment of the application can be movably arranged or fixedly arranged;

[0070] The first track 701 is a transversely extending track arranged at the bottom of the wall hanging machine and corresponding to part of the lower air outlet 102, the rear end of the first track 701 corresponds to the rear side of the lower air outlet 102, and the front end extends to the side of the front side of the lower air outlet 102; part of the second track 702 extends transversely and corresponds to another part of the lower air outlet 102, and the remaining part extends upward along the front side edge and the top side edge of the wall hanging machine to the rear side of the upper air outlet 101;

[0071] The channel groove extending vertically through is formed between the front rail end of the first rail 701 and the lower rail end of the second rail 702, and the bottom slot of the channel groove corresponds to the top end of the lower air deflector 40. The bottom end of the lapping air deflector 50 can pass through the channel groove and lap with the lower air deflector 40 when the lapping air deflector 50 is in the first position.

[0072] That is, in the embodiment, two filter screen rails are arranged, and the relative positions of the end portions of the two filter screen rails are arranged on the moving path of the lapping air deflector 50, that is, the gap between the end portions of the two filter screen rails constitutes a "channel groove" suitable for the movement of the lapping air deflector 50. Taking the example of the movable arrangement of the lapping air deflector 50, when the air conditioner needs to blow air downward, the lapping air deflector 50 can pass through the channel groove reserved between the first rail and the second rail like the partition plate of a drawer, and lap onto the lower air deflector 40 completely and intact; when the air conditioner needs to blow air upward, the lapping air deflector 50 can also neatly retreat to the separated position. In this way, the loss of air volume is minimized, and the noise also loses the amplifier of "air leakage", thereby improving the reversible air blowing effect of the wall-mounted machine.

[0073] Further, in some possible embodiments, when the air outlet mode of the wall-mounted machine is upper air inlet and lower air outlet, the first filter screen 601 moves to a position avoiding the lower air inlet 102, and the second filter screen 602 moves to a lower filtering position corresponding to the upper air inlet, so as to filter the air flow entering from the upper air inlet 101 through the second filter screen 602.

[0074] When the air outlet mode of the wall-mounted machine is lower air inlet and upper air outlet, the first filter screen 601 moves to a lower filtering position corresponding to the lower air inlet 102, and the second filter screen 602 moves to a lower filtering position avoiding the upper air inlet 101, so as to filter the air flow entering from the lower air inlet 102 through the first filter screen 601 and the second filter screen 602.

[0075] In the upper air inlet-lower air outlet mode, the second filter screen 602 moves upward along the second track 502 to the "upper filtering position" aligned with the rear side opening 101a of the upper air inlet 101; meanwhile, the first filter screen 601 moves backward along the first track 501 to completely leave the effective flow cross section of the lower air inlet 102. Thus, all the air flow entering the air duct is filtered through the second filter screen 602 only, and the filtering area corresponds to the opening area of the upper air inlet 101 in a 1:1 ratio, eliminating the additional resistance caused by the redundant coverage of the filter screen. In the lower air inlet-upper air outlet mode, the first filter screen 601 moves forward and covers the rear side area of the lower air inlet 102, and the second filter screen 602 moves downward along the second track 502 to the "lower filtering position" aligned with the front side area of the lower air inlet 102; the two filter screens form a continuous filtering surface on both sides of the channel groove, so that the entire air inlet of the lower air inlet 102 is double-filtered, ensuring that the filtering efficiency is still ≥99% under high air volume conditions.

[0076] Further, in some possible implementation manners, the front side track end of the first track 701 and the lower side track end of the second track 702 are at the same height position.

[0077] In the embodiment of the application, when the two ends of the two tracks are arranged at the same height, the height difference is 0, the opening of the channel groove in the width direction is rectangular, and a symmetrical slit sealing surface can be formed when the lapping air guide plate 401 passes through. Wind tunnel tests show that under this state, the vortex intensity of the slot is effectively reduced, and the additional noise caused by local turbulence is reduced.

[0078] Further, in some possible implementation manners, the air conditioner wall-mounted machine further comprises:

[0079] The first driving mechanism 801 comprises 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 filtering position corresponding to the lower air inlet 102, at least part of the first filter screen 601 is still in transmission cooperation with the first gear.

[0080] And / or

[0081] The second driving mechanism 802 comprises a second gear for driving the second filter screen 602 to move, wherein the length of the second filter screen 602 is configured such that when the second filter screen 602 moves to the filtering position corresponding to the lower air inlet 102 or the upper air inlet 101, at least part of the second filter screen 602 is still in transmission cooperation with the second gear.

[0082] In the embodiments of the present application, whether the first filter screen 601 is in the completely avoiding position or the lower filtering position, the rack section thereof is always engaged with the first gear; similarly, the second filter screen 602 is always engaged with the second gear in the whole stroke. Thus, the "idle stroke" or the risk of disengagement is eliminated, the positioning accuracy of the filter screen can be stabilized within ±0.3 mm, the amplitude of the filter screen shaking during the operation of the whole machine is reduced to 0.1 mm, and the jamming or noise peak caused by the engagement failure is avoided.

[0083] Further, in some possible implementations, the air conditioner wall-mounted machine further comprises:

[0084] a first cleaning assembly 901, the first cleaning assembly 901 comprising a first cleaning brush arranged on a moving path of the first filter screen 601, for cleaning the first filter screen in movement;

[0085] and / or

[0086] a second cleaning assembly, the second cleaning assembly comprising a second cleaning brush arranged on a moving path of the second filter screen, for cleaning the second filter screen in movement.

[0087] In the embodiments of the present application, the cleaning brush maintains constant line contact with the surface of the filter screen; when the filter screen reciprocates in the track, the brush body instantaneously peels off the attached fibers and dust, so that the resistance increment after a single cycle of the filter screen is significantly reduced, and the performance degradation caused by dust accumulation is effectively delayed.

[0088] Further, in some possible implementations, the overlapping air guide plate is configured as an arc-shaped air guide plate or a straight-faced 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 are respectively overlapped with the bottom end of the air duct wall and the top end of the lower air guide plate.

[0090] In the embodiments of the present application, when the overlapping air guide plate 401 is arc-shaped, the curvature thereof continuously transitions with the profile line of the air duct wall, so that the separation point of the boundary layer is delayed, and the actual measurement of the outflow uniformity under the outflow mode is significantly improved; if a straight-faced air guide plate is used, the same sealing performance is achieved by increasing the overlapping length, which is suitable for models with limited space of the volute, and the loss of aerodynamic efficiency is less than 1%.

[0091] Further, in some possible implementations, the lower air guide plate 40 is provided with a plurality of lower air guide plates 40, the plurality of lower air guide plates 40 comprising a front side air guide plate close to the front side edge of the lower air outlet 102, a rear side air guide plate close to the rear side edge of the lower air outlet 102, and at least one intermediate air guide plate between the front side air guide plate and the rear side air guide plate;

[0092] The bottom slot of the channel groove corresponds to the top end position of the intermediate air guide plate.

[0093] The slot of the channel groove in the embodiment of the application is arranged to be aligned with the middle air deflector 40c only, so that the lower air outlet area of the wall-mounted air conditioner in the upper air inlet-lower air outlet mode is reduced, the air outlet speed of the lower air outlet is improved, the airflow flowing out of the lower air outlet can have sufficient flow power to adhere to the wall and flow downward, and thus the carpet heating is realized.

[0094] Further, in some possible implementation manners, the wall-mounted air conditioner further comprises:

[0095] The movable volute tongue 1002 and the spoiler 1001 are oppositely arranged on the front and rear sides of the cross-flow fan blade 20, wherein the movable volute tongue 1002 is movably arranged on the front side of the cross-flow fan blade 20, and the spoiler 1001 is swingably arranged on the rear side of the cross-flow fan blade 20.

[0096] The movable volute tongue 1002, the spoiler 1001 and the overlapping air deflector 50 are configured to:

[0097] When the air outlet mode of the wall-mounted air conditioner is the upper air inlet-lower air outlet mode, the movable volute tongue 1002 moves downward to the lower working position, the spoiler 1001 swings forward to at least partially protrude from the rear air deflector wall of the air duct of the air conditioner, and the overlapping air deflector 50 moves to the first position, in which the top end of the overlapping air deflector 50 overlaps with the bottom end of the movable volute tongue 1002, and the bottom end overlaps with the top end of the lower air deflector 40, and the overlapping air deflector 50, the movable volute tongue 1002 and the lower air deflector 40 jointly constitute the front air deflector wall of the air duct 103.

[0098] When the air outlet mode of the wall-mounted air conditioner is the lower air inlet-upper air outlet mode, the movable volute tongue 1002 moves upward to the upper working position to constitute the front air deflector wall of the air duct 103, the spoiler 1001 swings backward to abut against the rear air deflector wall of the air duct 103, and the overlapping air deflector 50 moves to the second position, in which the top end of the overlapping air deflector 50 is spaced from the bottom end of the movable volute tongue 1002, and the bottom end is spaced from the top end of the lower air deflector 40.

[0099] In order to more clearly understand the wall-mounted air conditioner in the embodiment of the application, the following specifically describes the wall-mounted air conditioner in the embodiment of the application with reference to the accompanying drawings. Figures 1-6

[0100] ​Specifically, in the upper air outlet mode: for the refrigeration or air supply mode, because the hot air floats upwards, the heating hot air does not come down, which seriously affects the comfort. The shower type refrigeration is easily realized in the upper air outlet refrigeration, and the cold air does not blow on people. The spoiler 1001 is located at the initial position smoothly connected with the rear air duct wall, the movable volute tongue 1002 is moved upwards and lapped to the upper limit structure 1006 in the shape of water droplet, the lapped air deflector 50 is rotated to the second position separated from the front air duct wall and the lower air deflector, and the first filter screen 601 and the second filter screen 602 are operated to the lower air outlet 102. It should be noted that the shower type refrigeration is easily realized in the upper air outlet refrigeration, the cold air does not blow on people, the noise is low, and it is suitable for relatively quiet environment, such as sleep environment.

[0101] Specifically, in the lower air outlet mode: for the heating or air supply mode, the hot air is realized to be blown out from the bottom to realize the carpet type heating. The spoiler 1011 is located at the open position protruding from the rear air duct wall, the lapped air deflector 50 is rotated to the first position lapped with the front air duct wall and the lower air deflector, the bottom end of the movable volute tongue 1002 is lapped to the top end of the lower air deflector, the second filter screen 602 is operated to the upper air outlet position, and the first filter screen 601 is operated to the position avoiding the lower air outlet, so that the indoor air is blown out through the lower air outlet after being heat-exchanged through the evaporator from the top.

[0102] It can be seen that the air flow filtering effect in the reversible air supply is realized by the movement and cooperation of different filter screens in the present application. As shown in Figures 4-6 , the second filter screen can be inserted into the filter screen track from the filter screen assembly inlet 1005 of the panel body, the length lapping section is limited by the left and right track of the panel body, then the filter screen pressing plate 1004 is assembled to the panel body to press the second filter screen, and the filter screen pressing plate and the panel body together constitute a complete track. For disassembly of the second filter screen, the power is turned off after the second filter screen is operated to the upper air outlet, the filter screen pressing plate 1004 is opened, and the filter screen length lapping section is pulled out. The function of the filter screen length lapping section is to facilitate installation and disassembly, and to ensure that the panel body and the filter screen pressing plate are matched with the track position, the filter screen does not disengage and fail, that is, the filter screen runs across the splicing position of two parts and is not easy to deform and be stuck. It should be noted that the length lapping section of the second filter screen 602 refers to the filter screen section on the lower side of the driving gear when the upper end of the second filter screen 602 is operated to the position opposite to the rear side of the upper air outlet 101, as shown in Figure 2 , the length of the second filter screen on the lower side of the second driving mechanism 802 is the filter screen lapping section mentioned above.

[0103] The operation control mode of the filter screen will be introduced in detail as follows:

[0104] The indoor wall-hung machine detects whether the second filter screen is dirty and blocked. If not, the second filter screen is located at the lower air outlet position and does not need to move, and the indoor machine is normally started and operated. If yes, it is further detected whether the second filter screens on the left and right sides are both located at the lower air outlet position {it should be noted that from the front direction of the air conditioner, the conventional air conditioner has two filter screens on the left and right sides, and in the scheme of the embodiment of the application, there can be four filter screens, i.e., two filter screens on the left and right sides for the first filter screen and the second filter screen}. If yes, the second filter screens on the left and right sides are moved to the upper air outlet position, the indoor machine is stopped, the filter screen pressing plate is disassembled, and the second filter screen is taken out for cleaning. If not, if the second filter screens on the left and right sides are both located at the upper air outlet position, the second filter screens do not move, the indoor machine is turned off, and the second filter screens are cleaned. If the second filter screen on one side is located at the upper air outlet position, the second filter screen on the other side needs to be moved to the upper air outlet position first, and then the second filter screens on the left and right sides are disassembled and cleaned. After cleaning, the user installs the filter screen, and it is further detected whether the cleaned second filter screen is installed in place. If not, the second filter screen is moved to the upper air outlet position first, stopped after contacting the micro switch, and then moved to the lower air outlet position (the initial position of the second filter screen is the default position). If yes, the second filter screen is moved to the lower air outlet position, and it is further detected whether the first filter screen is dirty and blocked. If the first filter screen is dirty and blocked, the first filter screen is automatically rolled up and cleaned by the brush. If the first filter screen is not dirty and blocked, the brush does not rotate, the first filter screen does not need to be cleaned, and the indoor machine is normally operated.
