Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of air conditioning, and particularly relates to an air conditioner. BACKGROUND

[0002] As a daily household appliance in life, the air conditioner has a large amount of dust accumulated on the surface of the air duct after a long time of placement or use. In a humid environment, the dust provides a sticking point for bacteria, and thus a large amount of bacteria breed, affecting the health of users. In addition, after the fan is started, the air blown out has a moldy smell, and the experience effect is poor. Ordinary users have difficulty in disassembling and cleaning the air conditioner, and the cleaning is not thorough, and the components of the air conditioner are easily damaged.

[0003] In order to solve the foregoing problems, a corresponding cleaning structure is arranged in the air outlet air duct of the air conditioner in the related art to clean the dust on the inner wall of the air duct. For example, the related patent provides an automatic cleaning device and an air conditioner, which include a brush and two transmission mechanisms. The transmission mechanisms are arranged on the two side walls of the air duct, and are connected with the two ends of the brush respectively, for driving the brush to slide back and forth along the air duct, so as to sweep the dust on the air duct and the air wheel down. When the brush slides downward, the swept dust is brought to the air outlet end of the air duct, and the dust is sucked away by the dust suction baffle. The structure causes the air conditioner to be unable to normally blow and blow out air when the air duct is cleaned, that is, the normal use of the air conditioner is affected when the air duct is cleaned. SUMMARY

[0004] Therefore, the present application provides an air conditioner, which can solve the technical problem that the normal use of the air conditioner is affected when the inner wall of the air outlet air duct of the air conditioner is cleaned in the prior art.

[0005] In order to solve the foregoing problems, the present application provides an air conditioner, which includes:

[0006] An air outlet air duct, which includes a first air duct wall body;

[0007] A flexible wall, which includes a first wall surface having a first dust collecting position in the air outlet air duct and capable of covering the windward surface of the first air duct wall body, and a first cleaning position outside the air outlet air duct and capable of being cleaned by a cleaning mechanism, and the first wall surface is capable of being driven to switch between the first dust collecting position and the first cleaning position.

[0008] In some embodiments,

[0009] The flexible wall further comprises a second wall surface, corresponding ends of the first wall surface and the second wall surface being connected to form a whole, the second wall surface having a second dust collection position in the air outlet air duct and capable of covering the windward surface, the second wall surface further having a second cleaning position outside the air outlet air duct and capable of being cleaned by the cleaning mechanism, the second wall surface being capable of being driven to switch between the second dust collection position and the second cleaning position, and the first wall surface and the second wall surface alternately forming positions in the air outlet air duct.

[0010] In some embodiments,

[0011] The material of the flexible wall is a fiber composite material.

[0012] In some embodiments, the air conditioner further comprises:

[0013] A position switching driving assembly, comprising a first driving motor and a driving roller sleeved on a rotating shaft of the first driving motor, and teeth on the driving roller being engaged with tooth grooves on the flexible wall.

[0014] In some embodiments,

[0015] The position switching driving assembly further comprises a driven roller, the driven roller being arranged in parallel and spaced apart from the driving roller, and the flexible wall being wrapped and tensioned on the driven roller and the driving roller.

[0016] In some embodiments, the cleaning mechanism comprises:

[0017] A rolling brush assembly, comprising a rolling brush and a second driving motor for driving the rolling brush to rotate, the rolling brush being capable of abutting against an outer surface of the first wall surface or the second wall surface.

[0018] In some embodiments, the cleaning mechanism further comprises:

[0019] A water tank having a water containing cavity, the rolling brush being at least partially in the water containing cavity and at least partially below a water surface in the water containing cavity.

[0020] In some embodiments, the cleaning mechanism further comprises:

[0021] A sterilization component for sterilizing a part of the flexible wall in the water containing cavity.

[0022] In some embodiments,

[0023] The sterilization component is arranged at a position corresponding to a position of the part of the flexible wall after being cleaned by the rolling brush.

[0024] In some embodiments,

[0025] The flexible wall has a limiting structure between the flexible wall and the first air duct wall body.

[0026] The air conditioner provided by the application has the following beneficial effects:

[0027] The first wall surface is arranged on the windward surface of the first air duct wall body of the air outlet air duct, so that dust in the air outlet air duct is deposited on the first wall surface and is not deposited on the first air duct wall body. When the air outlet air duct needs to be cleaned, the first wall surface can be switched from the first dust collecting position to the first cleaning position. Since the first cleaning position is outside the air outlet air duct, the normal use of the air conditioner is not affected when the cleaning operation of the air outlet air duct is performed, and the user's satisfaction with the product is improved.

[0028] The flexible wall has the first wall surface and the second wall surface with the integrated structure, both of which have the cleaning position and the dust collecting position, and the cleaning position and the dust collecting position of the two are alternated, so that when one of the wall surfaces is cleaned, the other wall surface is switched to the corresponding dust collecting wall surface at the same time, thereby achieving full-time and full-range coverage and shielding of the windward surface of the first air duct wall body, and preventing the first air duct wall body from being exposed and causing dust accumulation when the corresponding wall surface is cleaned.

[0029] The roller brush is at least partially submerged in the water in the water tank, so that the roller brush can be wetted. The wetted roller brush can more effectively clean and wash the outer wall surface of the flexible wall, that is, the dirt removal is more thorough. At the same time, the water in the water tank can also clean the roller brush, thereby ensuring the cleanliness of the roller brush itself. BRIEF DESCRIPTION OF DRAWINGS

[0047] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The description of the at least one exemplary embodiment is actually only illustrative, but not as any limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0048] In the description of the present application, it needs to be understood that the orientation words such as "front, back, upper, lower, left, right", "transverse, vertical, perpendicular, horizontal" and "top, bottom" and the like indicated orientation or position relationship is generally based on the orientation or position relationship shown in the drawings, only for the convenience of describing the present application and simplifying the description, without making the opposite statement, these orientation words do not indicate and imply that the indicated device or element must have a particular orientation or be constructed and operated in a particular orientation, therefore cannot be understood as a limitation on the scope of protection of the present application; the orientation words "inner, outer" refer to the inner and outer relative to the contour of each component.

[0049] For the convenience of description, spatial relative terms such as "over", "above", "upper surface", "upper" and the like can be used herein to describe the spatial position relationship of one device or feature with other devices or features as shown in the drawings. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation of the device described in the drawings. For example, if the device in the drawing is inverted, the device described as "above" or "over" other devices or structures will be positioned "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below" orientations. The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein are interpreted accordingly.

[0050] In addition, it needs to be noted that the use of "first", "second" and the like to define parts is only for the convenience of distinguishing the corresponding parts, and the above words have no special meaning unless otherwise stated, therefore cannot be understood as a limitation on the scope of protection of the present application.

[0051] For reference Figures 1 to 4 As shown in the drawings, according to the embodiment of the present application, an air conditioner is provided, comprising a bottom shell 102, an inner cavity is formed on the bottom shell 102, a fan 101 (for example Figure 1 A cross-flow fan applied in a wall-mounted air conditioner is shown in the drawings) and a heat exchanger 100 at the air inlet side of the fan 101, the bottom shell 102 also has an air outlet air duct 1, the air outlet air duct 1 comprises a first air duct wall body 11, which is the wall body in the air outlet air duct 1 that is more prone to dust deposition;

[0052] The flexible wall 2 is independently arranged from the first air duct wall body 11, and specifically includes a first wall surface 21, which has a first dust collection position in the air outlet air duct 1 and capable of covering the windward surface of the first air duct wall body 11, and has a first cleaning position outside the air outlet air duct 1 and capable of being cleaned by the cleaning mechanism 3. The first wall surface 21 is capable of being driven to switch between the first dust collection position and the first cleaning position. It can be understood that when the first wall surface 21 covers the windward surface of the first air duct wall body 11, it will form a shielding protection for the windward surface of the first air duct wall body 11. Correspondingly, the dust will be collected and deposited on the outer side of the first wall surface 21, i.e. the side of the flexible wall 2 away from the windward surface.

[0053] In the technical scheme, the first wall surface 21 is arranged on the windward surface of the first air duct wall body 11 of the air outlet air duct 1, so that the dust in the air outlet air duct 1 is deposited on the first wall surface 21 instead of the first air duct wall body 11. When the air outlet air duct 1 needs to be cleaned, the first wall surface 21 can be switched from the first dust collection position to the first cleaning position. Since the first cleaning position is outside the air outlet air duct 1, the normal use of the air conditioner will not be affected when the cleaning operation of the air outlet air duct 1 is performed, and the user's satisfaction with the product can be improved.

[0054] In another preferred embodiment, the flexible wall 2 further includes a second wall surface 22, and the first wall surface 21 and the second wall surface 22 are connected to form an integral structure. Specifically, the first wall surface 21 and the second wall surface 22 form a substantially annular structure, and the second wall surface 22 has a second dust collection position in the air outlet air duct 1 and capable of covering the windward surface, and has a second cleaning position outside the air outlet air duct 1 and capable of being cleaned by the cleaning mechanism 3. The second wall surface 22 is capable of being driven to switch between the second dust collection position and the second cleaning position. The first wall surface 21 and the second wall surface 22 form position alternation in the air outlet air duct 1. Specifically, when the first wall surface 21 is in the first dust collection position, the second wall surface 22 is in the second cleaning position, and when the first wall surface 21 is switched to the first cleaning position, the second wall surface 22 is in the second dust collection position.

[0055] In the technical solution, the flexible wall 2 has the first wall surface 21 and the second wall surface 22 with integrated structures, both of which have cleaning positions and dust collecting positions, and the cleaning positions and the dust collecting positions of the two wall surfaces are alternated, so that when one of the wall surfaces is cleaned, the other wall surface is switched to the corresponding dust collecting wall surface at the same time, thereby achieving full-time and full-direction coverage of the windward surface of the first air duct wall body 11, and preventing the first air duct wall body 11 from being exposed to cause dust accumulation when the corresponding wall surface is cleaned.

[0056] The flexible wall 2 is preferably made of a material that is waterproof, high-temperature resistant, and has a certain deformation ability. In a specific embodiment, the material of the flexible wall 2 is a fiber-reinforced composite material, which is a relatively common material on the market and can reduce manufacturing costs.

[0057] The position switching of the first wall surface 21 and the second wall surface 22 can of course be set according to the user's needs to set up a corresponding manual power switching structure. In order to ensure the automation degree of air duct cleaning, in some embodiments, the air conditioner further comprises a position switching driving assembly (not shown in the figure), which includes a first driving motor 41 (specifically a rotary motor) and a driving roller 42 sleeved on the shaft of the first driving motor 41. The teeth on the driving roller 42 are engaged with the tooth grooves 23 on the flexible wall 2. Specifically, the driving roller 42 is arranged on the back surface of the first air duct wall body 11, and the tooth grooves 23 are arranged on the left and right width edges of the flexible wall 2. Figure 1 The position switching driving assembly is arranged on the back surface of the first air duct wall body 11, and the tooth grooves 23 are arranged on the left and right width edges of the flexible wall 2. The position switching driving assembly is arranged on the back surface of the first air duct wall body 11, and the tooth grooves 23 are arranged on the left and right width edges of the flexible wall 2.

[0058] Two bearing assemblies are arranged on the leeward side wall surface of the first air duct wall body 11, and the driving roller 42 is arranged between the two bearing assemblies to ensure the position reliability and driving stability of the driving roller 42.

[0059] Referring to Figure 3 and Figure 4 In some embodiments, the position switching driving assembly further comprises a driven roller 43, which is arranged in parallel with the driving roller 42. The flexible wall 2 is tensioned around the driven roller 43 and the driving roller 42. Specifically, the two ends of the driven roller 43 are also rotatably supported and connected to the leeward surface of the first air duct wall body 11 through corresponding bearing assemblies.

[0060] In the technical solution, the tension of the flexible wall 2 on both sides is formed by the driving roller 42 and the driven roller 43, so that the position switching of the flexible wall 2 is more smooth.

[0061] In some embodiments, the cleaning mechanism 3 is assembled on the bottom shell 102, and the cleaning mechanism 3 comprises a roller brush assembly (not shown in the figure) including a roller brush 31 (which can be a hairbrush) and a second driving motor 32 (which can be a rotary motor) for driving the roller brush 31 to rotate. The roller brush 31 can be in contact with the outer side of the first wall surface 21 or the second wall surface 22, so that the first wall surface 21 and the second wall surface 22 can be effectively cleaned by the roller brush 31.

[0062] In the technical solution, the first wall surface 21 or the second wall surface 22 in the cleaning position is cleaned by the roller brush 31 on the outer side of the air outlet duct 1, which is simple in structure and convenient to operate.

[0063] In some embodiments, the cleaning mechanism 3 further comprises a water tank 33 having a water containing cavity, and the roller brush 31 is at least partially in the water containing cavity and at least partially below the water surface in the water containing cavity.

[0064] In the technical solution, the roller brush is at least partially below the water surface in the water containing cavity and can be wetted. The wetted roller brush 31 can more effectively clean the outer wall surface of the flexible wall 2, that is, the dirt is more thoroughly removed. At the same time, the water in the water tank 33 can also clean the roller brush 31 to ensure the cleanliness of the roller brush 31 itself.

[0065] It can be understood that the water tank 33 is also provided with a corresponding water inlet and a water outlet to supplement water in time when the water in the water tank 33 is insufficient, and to drain and replace water when the water is seriously contaminated. In another preferred embodiment, the water tank 33 can also communicate with the drain hole of the water pan of the air conditioner to utilize the condensation water generated during the operation of the air conditioner.

[0066] In some embodiments, the cleaning mechanism 3 further comprises a sterilization component 34 for sterilizing part of the flexible wall 2 in the water containing cavity. The sterilization component 34 can be, for example, an ultraviolet generator on the market, so as to achieve more thorough cleaning.

[0067] In a preferred embodiment, the sterilization component 34 is arranged at a position corresponding to part of the flexible wall 2 cleaned by the roller brush 31, that is, the subsequent sterilization operation is performed after the flexible wall 2 is cleaned by the roller brush 31, effectively preventing the pollution of the bacteria carried by the roller brush 31 to the flexible wall 2.

[0068] In order to ensure that the flexible wall 2 can be attached to the profile of the first air duct wall body 11 in the air outlet air duct 1, thereby ensuring that the air outlet line of the air outlet air duct 1 is on the target path, the flexible wall 2 and the first air duct wall body 11 have a limiting structure, that is, the limiting structure can make the appearance shape of the flexible wall 2 in the air outlet air duct 1 consistent with the profile of the windward surface of the first air duct wall body 11, that is, attached as a whole. The aforementioned limiting structure may, for example, include a sliding groove formed on the windward surface of the first air duct wall body 11 and a sliding block formed on the side of the flexible wall 2 facing the aforementioned windward surface. The cross section of the sliding block and the sliding groove is trapezoidal, so that the sliding block can be connected to the sliding groove in a non-falling manner. It can be understood that the length extension direction of the aforementioned sliding groove and sliding block should be consistent with the position switching direction of the flexible wall 2.

[0069] Specifically referring to Figure 3 The orientation shown is used to describe the cleaning process of the present application: when the user issues a cleaning instruction for the air outlet air duct 1, the first drive motor 41 drives the driving roller 42 to rotate counterclockwise, thereby driving the flexible wall 2 to rotate counterclockwise. At the same time, the second drive motor 2 drives the roller brush 31 to rotate to clean the area of the flexible wall 2 in contact with it. With the driving of the first drive motor 41, the first wall surface 21 in the air outlet air duct 1 is completely transferred from inside the air outlet air duct 1 to outside the air outlet air duct 1, that is, the first wall surface 21 is completely switched from the first dust collecting position to the first cleaning position. In this process, the sterilization component 34 is also controlled to operate to sterilize the cleaned flexible wall 2, ensuring the cleanliness of the flexible wall 2. At the same time, the second wall surface 22 originally outside the air outlet air duct 1 is completely inside the air outlet air duct 1 to replace the first wall surface 21. Thus, a cleaning cycle is completed. When cleaning is selected again, the second wall surface 22 in the air outlet air duct 1 is replaced by the first wall surface 21 outside the air outlet air duct 1.

[0070] Specifically referring to Figure 3 As shown, the aforementioned flexible wall 2 forms an inside and outside surrounding of at least one area of the first air duct wall body 11. At this time, corresponding through holes (or through grooves) are formed on the first air duct wall body 11 to ensure that the flexible wall 2 can pass through them. However, it should be noted that the position of the through hole should be sealed, for example, a flexible sealing baffle is provided, etc., to reduce the adverse effects (wind resistance) of opening the through hole on the air flow.

[0071] The aforementioned first air duct wall body 11 is the wall body in the air outlet air duct 1 that is prone to dust deposition. For example, for a wall-mounted air conditioner, the aforementioned first air duct wall body 11 is the bottom side wall body of the air outlet air duct 1 (the orientation is below the wall body). It can be understood that the probability of dust deposition on the top side wall body is relatively low, so the necessity of cleaning is not strong.

[0072] The above merely describes preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application. The above merely describes preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
