The utility model provides a wall-mounted air conditioner indoor unit.

In the embodiment of the present invention, as shown in fig. 1 to 3, the wall-mounted air conditioner indoor unit includes a casing 10, a purification module 20, and a driving mechanism 30. Wherein, the top of the casing 10 is provided with an air inlet 11, and at least a part of the purification module 20 is movably arranged at the air inlet 11. The driving mechanism 30 is used to drive the movable portion of the purification module 20 to ascend or descend relative to the air inlet 11, so as to form an air inlet gap between the purification module 20 and the housing 10.

It can be understood that, in a typical wall-mounted air conditioner indoor unit, the purification module is installed at the air inlet of the body to purify the indoor air. Because the air permeability of the purification module is poor, the purification module is arranged at the air inlet of the indoor unit, and when air passes through the purification module, the air resistance of the air inlet is increased due to large resistance. So, can cause the intake loss of air intake serious, for guaranteeing the air output, the operating power of machine in the air conditioning can improve, has increased noise at the same time again. To the above problem, the utility model discloses technical scheme is through installing purification module 20 at least partly movably in air intake 11 to but order about purification module 20's mobile part through actuating mechanism 30 and rise or descend for air intake 11, and make and form the overfire air clearance between purification module 20 and casing 10. Here, the purification module 20 can be raised and lowered as a whole or partially compared to the housing 10. No matter the purification module 20 is lifted integrally or partially, air can flow into the shell 10 from the air inlet gap after the purification module 20 is lifted/lowered, so that the wind resistance of the air inlet 11 can be reduced, and the air volume loss is reduced; meanwhile, the indoor unit can ensure the air output only by improving the power in a small range or without improving the power, thereby reducing the working noise. It is thus clear that compare in common air conditioning indoor set, the wall-hanging air conditioning indoor set of this application has the air loss and is few, and noise at work is little advantage.

Optionally, in this embodiment, the purification module 20 is a formaldehyde purification module. The formaldehyde purification module 20 is a kind of the purification module 20, and is generally composed of a filter screen (filter element) having a physical adsorption capability, or a filter element having an electrostatic adsorption capability, or may be composed of a filter element having an ion adsorption capability. Of course, the design of the present application is not limited thereto, and in other embodiments of the present application, other modules may be used as the purification module 20, such as an IFD, a HAPA net, a sterilization module, a dust removal module, and other air purification modules.

Alternatively, in the present embodiment, the whole of the purification module 20 can be lifted compared to the air inlet 11. It can be understood that the purification module 20 is set to be wholly liftable compared with the air inlet 11, the purification module 20 is kept in a whole in the lifting process, the shape of the purification module is not easy to deform by external force, and the service life of the purification module 20 is prolonged. Meanwhile, the integral lifting of the purification module 20 can simplify the structural design of the driving mechanism 30 and the shell 10, which is beneficial to the production and manufacture of the indoor unit. Of course, in other embodiments of the present application, the purification module 20 may be only partially liftable with respect to the intake vent 11.

Based on the solution that the purification module 20 is lifted as a whole, the present embodiment further proposes that the purification module 20 has a covering state of being lowered to cover the air inlet 11 and a disengaging state of being lifted to disengage from the air inlet 11. When the purification module 20 is in the covering state, the purification module 20 is in contact with the casing 10 around the air inlet 11, and when the purification module 20 is in the disengaging state, the purification module 20 is separated from the casing 10 around the air inlet 11. That is, in the present embodiment, the purification module 20 is lifted from the outside of the housing 10 compared to the intake vent 11. With such an arrangement, the movable space of the purification module 20 does not need to be reserved inside the indoor unit casing 10, which is beneficial to simplifying the structural design inside the casing 10 and is also beneficial to increasing the movable space of the purification module 20. Of course, in other embodiments, the purification module 20 can also be lifted and lowered inside the housing 10 compared to the air inlet 11.

It will be understood that, depending on the state of the purification module 20, the indoor unit can have the following two modes of operation: a purge mode and a normal mode. When the indoor unit is in the purification mode, the purification module 20 covers the air inlet 11; when the indoor unit is in the normal mode, the purification module 20 is separated from the air inlet 11. Regarding the application scenarios of the two states, the present embodiment takes the purification module 20 as a formaldehyde purification module as an example, and an exemplary description is given: the indoor unit further comprises a formaldehyde concentration detection module, when the indoor formaldehyde concentration is higher than a preset value, the indoor unit operates in a purification mode, and when the indoor formaldehyde concentration is lower than the preset value, the indoor unit operates in a common mode. So, switch between two kinds of mode through the indoor set, can have except that two kinds of effects of formaldehyde and silence concurrently to furthest promotes user experience.

It should be noted that, since the ascending/descending distance of the purification module 20 compared to the air inlet 11 is controllable, and the ascending/descending distance of the purification module 20 is different, the air passing area of the air inlet gap is different accordingly. Thus, the lifting distance of the purification module 20 can be controlled according to the indoor air quality, so that the air enters the casing 10 only through the purification module 20, or enters the casing 10 only through the air inlet gap, or enters the casing 10 through the air inlet gap and the purification module 20 at the same time. Therefore, the indoor unit has multiple working modes and can adapt to more using environments.

Optionally, in this embodiment, the air inlet 11 is provided with an air inlet grille. It can be understood that the air inlet grille is disposed at the air inlet 11 to protect the internal structure of the housing 10, and to abut against the purification module 20 when the purification module 20 descends, so as to limit and support the purification module 20.

Specifically, the driving mechanism 30 of the present embodiment includes a lifting member 31, and one end of the lifting member 31 is connected to the purification module 20, and the other end is liftably mounted to the housing 10. Like this, drive purification module 20 through lifting member 31 and go up and down, simple structure realizes the convenience. Specifically, in the present embodiment, the housing 10 is provided with a position avoiding opening, and the lifting member 31 is installed in the position avoiding opening in a lifting manner, in other embodiments, the lifting member 31 may also be installed in the air inlet 11, or a corresponding structure is provided outside the housing 10 for the lifting member 31 to be installed in a lifting manner.

As shown in fig. 2 to 7, the driving mechanism 30 of the present embodiment further includes a motor 32 and a transmission member 33, and the motor 32 drives the lifting member 31 to lift through the transmission member 33. It can be appreciated that the motor 32 is a common driving member, and has the advantages of mature control mode and easy access. Meanwhile, the rotation angle and the rotation speed of the output shaft of the motor 32 are controllable, the motor 32 is selected to drive the lifting piece 31 to lift, and the lifting distance and the starting and stopping of the purification module 20 can be accurately controlled. And the transmission member 33 is used for transmitting power between the motor 32 and the lifting member 31. Of course, the design of the present application is not limited thereto, and since the lifting member 31 only performs the lifting motion, in other embodiments, the lifting member 31 may be driven to lift by pneumatic (e.g., an air cylinder) or hydraulic (e.g., a hydraulic cylinder) or the like.

Referring to fig. 6 and 7, in the present embodiment, the lifting member 31 is a rack, and the transmission member 33 includes a gear 332, and the gear 332 is engaged with the rack. Specifically, the motor 32 drives the elevating member 31 to ascend and descend by rotating the driving gear 332. It can be understood that the meshing transmission between the gear 332 and the rack can not only improve the motion precision of the lifting member 31, but also improve the motion stability of the lifting member 31. Thereby improving the movement accuracy and the movement stability of the purification module 20. Meanwhile, the motor 32 drives the lifting piece 31 to lift through the gear 332, the transmission piece 33 is simple in structure, the occupied space in the shell 10 is small, and the space design inside the shell 10 is facilitated. Of course, the design of the present application is not limited to this, and in other embodiments of the present application, the motor 32 may also drive the lifting member 31 to lift through a transmission structure such as a screw-slider structure, a crank-slider structure, a worm-gear structure, and the like.

Further, in this embodiment, the transmission member 33 further includes a transmission shaft 331, at least two gears 332 are spaced apart from the transmission shaft 331, each gear 332 is engaged with a rack, and each rack is connected to the purification module 20. It is understood that by providing at least two gears 332 on a rack, each gear 332 is engaged with a rack, and each rack is in turn connected to the purification module 20. Thus, when the transmission shaft 331 rotates, a plurality of racks can be driven to synchronously lift. So, not only the purification module 20 forms the multiple spot support through many racks to many racks go up and down in step, spacing each other between rack and the rack, stability when can further promote purification module 20 motion and static.

Specifically, in the present embodiment, the transmission shaft 331 extends in the width direction of the housing 10, and two gears 332 are provided on the transmission shaft 331 at an interval. Of course, in other embodiments, the transmission shaft 331 may also extend along the length direction of the casing 10, or along a diagonal direction of the casing 10, which is not limited in this application. The transmission shaft 331 can be correspondingly provided with 3, 4, 5 or even more gears 332.

It should be noted that the motor 32 may be directly connected to the transmission shaft 331 through a coupling, so as to directly drive the transmission shaft 331, or indirectly drive the transmission shaft 331 to rotate through a transmission component such as a speed reducer, a transmission belt, etc. In some embodiments, the motor 32 can also directly drive the gear 332 to rotate, thereby driving the transmission shaft 331 to rotate.

Referring to fig. 3, 6 and 8, in the present embodiment, at least two transmission members 33 are disposed at intervals along the length direction of the housing 10, and each transmission member 33 is correspondingly connected to one lifting member 31. It can be understood that by providing at least two transmission members 33 in the length direction of the housing 10, and connecting at least one lifting member 31 to each transmission member 33, the supporting strength of the driving mechanism 30 to the purification module 20 can be improved, and the stability of the purification module 20 in the moving and stationary states can be improved. Specifically, in the present embodiment, two transmission members 33 are disposed along the length direction of the housing 10, and each transmission member 33 is connected to two lifting members 31. Of course, in other embodiments, 3, 4, 5 or even more transmission members 33 may be provided on the housing 10, and the lifting member 31 connected to the transmission member 33 may be 1, 3, 4 or more. Further, the plurality of transmission members 33 may be provided at intervals in the width direction of the housing 10.

Further, in the present embodiment, the plurality of transmission members 33 transmit the transmission synchronously. It will be appreciated that this improves the coordination of the movement of the plurality of drives 33 and provides more stable lifting of the purification module 20. It should be noted that, in the present embodiment, each transmission member 33 is driven by one motor 32, and the motors 32 are controlled by the control system of the indoor unit to keep synchronous start and stop. Of course, in other embodiments, a plurality of transmission members 33 may be driven by the same motor 32.

In another embodiment of the present application, as shown in fig. 9, the plurality of transmission members 33 are driven asynchronously. At this time, the elevating member 31 is rotatably connected to the purification module 20. Taking the case of two transmission members 33 disposed on the housing 10 as an example, since the two transmission members 33 are asynchronously driven, two sides of the purification module 20 can be lifted to different heights compared to the air inlet 11, i.e., the purification module 20 can be moved to an inclined state. Therefore, the adjustable range of the air inlet gap is increased, and the air inlet gap can adapt to more use environments. It should be noted that, since the two transmission members 33 are driven asynchronously, there is a situation that one side of the purification module 20 is lifted up compared to the air inlet 11, and the other side is rotated compared to the housing 10, at this time, since the purification module 20 is in an inclined state, it can still be considered that the purification module 20 is lifted up and down compared to the air inlet 11. It should also be noted that, since the plurality of transmission members 33 are driven asynchronously, each transmission member 33 is driven by a motor 32.

In yet another embodiment of the present application, as shown in fig. 10, the purification module 20 includes a fixed portion 21 and a movable portion 22, wherein the fixed portion 21 is fixedly mounted to the intake vent, and the movable portion 22 can be lifted and lowered relative to the intake vent 11 by the driving mechanism 30. It will be appreciated that in this embodiment, the purification module 20 is partially liftable with respect to the intake opening 11, and thus the purification module 20 is always partially covering the intake opening 11. When the indoor unit works, the indoor air can be purified in real time by the indoor unit, and the quality of the indoor air is improved. Meanwhile, the driving mechanism 30 can drive the movable portion 22 of the purification module 20 to rise or fall according to the indoor air quality, and compensate the air volume loss of the air inlet 11 caused by the fixed portion 21 of the purification module 20 through the air inlet gap between the movable portion 22 and the casing 10, thereby reducing the working noise of the indoor unit.

Alternatively, the movable portion 22 and the fixed portion 21 are arranged in the length direction or the width direction of the housing 10. Because the casing 10 is rectangular, the movable portion 22 and the fixing portion 21 are arranged along the length direction or the width direction of the casing 10, the installation of the purification module 20 is convenient, the structural design is simple, and the movable portion 22 is easy to lift and form an air inlet gap with the casing 10. Of course, the design of the present application is not limited thereto, and in other embodiments of the present application, the fixed portion 21 and the movable portion 22 may be arranged in other manners, such as along a diagonal direction of the housing 10.

With continued reference to FIG. 10, in this embodiment, the fixed portion 21 is disposed on one side of the purification module 20 and the movable portion 22 is disposed on the other side of the purification module 20. Thus, under the driving of the driving mechanism 30, one side of the purification module 20 can be raised or lowered relative to the air inlet 11, and the other side is fixed, so that the form change of the purification module 20 is simple, which is beneficial to simplifying the structural design of the purification module 20. Furthermore, since the form change degree of the purification module 20 is small, the movable portion 22 can maintain good restoration capability even after long-term use, thereby prolonging the service life of the purification module 20.

In another embodiment of the present application, as shown in fig. 11, a fixed portion 21 is located between two movable portions 22. Taking the purification module 20 having a fixed portion 21 and two movable portions 22 as an example, after the driving mechanism 30 drives the movable portions 22 to move up/down, the middle portion of the purification module 20 is fixed, and the two ends of the purification module are tilted up or tilted down relative to the air inlet 11. In this state, the air intake of the air intake gap can be increased, and the air loss of the air intake 11 can be compensated to a greater extent. Of course, in other embodiments, the purification module 20 may also include a plurality of fixed portions 21 and movable portions 22, and the plurality of fixed portions 21 and movable portions 22 are disposed at intervals, so that at least one fixed portion 21 is located between two movable portions 22.

In another embodiment of the present application, as shown in fig. 12, a movable portion 22 is located between two fixed portions 21. Taking the purification module 20 having a movable portion 22 and two fixing portions 21 as an example, after the driving mechanism 30 drives the movable portion 22 to move up/down, the two ends of the purification module 20 are fixed, and the middle portion of the purification module is tilted up or tilted down relative to the air inlet 11. In this state, the covering portion of the purification module 20 at the air inlet 11 can be increased, and the purification capacity of the purification module 20 for indoor air can be improved to a minimum, thereby ensuring the purification effect of the purification module 20. Of course, in other embodiments, the purification module 20 may also include a plurality of fixed portions 21 and movable portions 22, and the plurality of fixed portions 21 and movable portions 22 are disposed at intervals, so that at least one movable portion 22 is located between two fixed portions 21.

Alternatively, the purification module 20 may be provided as a flexible member when the purification module 20 is only partially liftable with respect to the air intake. Like flexible filter screen, filter pulp, filter core etc. fixed part 21 can form with movable part 22 integratively like this, simple structure, and the cost is controllable, and utilizes the flexibility of flexible piece, and when actuating mechanism 30 drive movable part 22, required drive power is littleer, and drives movable part 22 more easily and goes up and down. Of course, the design of the present application is not limited thereto, and in other embodiments, the purification module 20 may also be a rigid member, in which case the fixed portion 21 is rotatably connected with the movable portion 22.
