A filter is provided near the upper air outlet of the air duct. When the upper air outlet is used for air outlet, the filter needs to be opened to prevent the filter mesh from blocking the wind directly facing the air outlet and affecting the air outlet effect; when the upper air outlet is used for air intake, the filter needs to be closed to filter the air flow entering the air duct to prevent dust from directly entering the evaporator and causing serious pollution inside the evaporator.

[0003] However, the cabinet with reversible air outlet in the prior art has the problem that the filter cannot be switched between the open and closed modes. Summary of the Invention

[0004] The main purpose of the present invention is to provide a filter mechanism and an air conditioner having the same, so as to solve the problem in the prior art of cabinet units with reversible air outlets up and down that the filter element cannot be switched between open and closed modes.

[0005] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, a filter screen mechanism is provided, comprising: a mounting frame, wherein one end of the mounting frame is provided with a accommodating chamber and a first opening portion connected to the accommodating chamber; a reel, which is rotatably arranged in the accommodating chamber around its axis; a filter screen member, wherein one end of the filter screen member is connected to the reel, and the other end of the filter screen member extends to the outside of the first opening portion, so that the filter screen member is driven to move relative to the mounting frame through the rotation of the reel, so that the filter screen member is wound on the reel or flattened on the mounting frame.

[0009] Furthermore, there are two guide grooves, which are respectively arranged corresponding to the opposite sides of the filter mesh element, so that the opposite sides of the flattened part of the filter mesh element are respectively located in the two guide grooves.

[0010] Furthermore, an elastic member is provided in the guide groove, the first end of the elastic member is connected to the second end of the filter mesh member, and the second end of the elastic member is connected to the end of the guide groove away from the reel, so as to assist in pulling the second end of the filter mesh member away from the reel when the reel drives the filter mesh member to gradually flatten on the mounting frame.

[0025] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] like Figures 1 to 5 As shown, the present invention provides a filter mechanism, comprising: a mounting frame 1, wherein one end of the mounting frame 1 is provided with a receiving chamber 10 and a first opening portion communicating with the receiving chamber 10; a reel 2, wherein the reel 2 is rotatably disposed in the receiving chamber 10 around its axis; and a filter mesh member 3, wherein one end of the filter mesh member 3 is connected to the reel 2, and the other end of the filter mesh member 3 extends to the outside of the first opening portion, so that the filter mesh member 3 is driven to move relative to the mounting frame 1 by the rotation of the reel 2, so that the filter mesh member 3 is wound on the reel 2 or flattened on the mounting frame 1.

[0027] The filter mechanism of the present invention comprises a reel 2 disposed within a housing 10 at one end of a mounting frame 1 containing a filter element 3. One end of the filter element 3 is fixedly connected to the reel 2, so that the filter element 3 can be wound around the reel 2 or flattened onto the mounting frame 1 by rotation of the reel 2. The filter mechanism is disposed in the air duct of an air conditioner with vertically reversible airflow, near the upper air outlet. When the upper air outlet is the air outlet, the filter mechanism is in an open position, with the filter element 3 wound around the reel 2, reducing wind resistance of the filter mechanism and achieving high airflow and better cooling performance. When the upper air outlet is the air inlet, the filter mechanism is in a closed position, with the filter element 3 flattened on the mounting frame 1, filtering airflow entering the air conditioner to prevent the ingress of dust and foreign matter. This solves the problem of conventional cabinet air conditioners with vertically reversible airflow, which suffers from the inability to switch the filter between open and closed positions.

[0028] Specifically, the filter mechanism further includes a driving component 5 , which is disposed on the mounting frame 1 and is drivingly connected to the reel 2 to drive the reel 2 to rotate around its axis.

[0029] Specifically, the driving component 5 is a motor, which is mounted on the mounting frame 1 , and the output shaft of the motor is coaxially connected to the reel 2 to drive the reel 2 to rotate.

[0030] like Figure 1 As shown, the filter mechanism of the present invention includes two motors, both of which are mounted on a mounting frame 1 and are respectively located at the axial ends of the reel 2, and their output shafts are respectively connected to the corresponding reel 2 to synchronously drive the reel 2 to rotate.

[0031] like Figure 3 and Figure 4 As shown, a mounting groove 20 is provided on the outer peripheral surface of the reel 2; the filter mesh member 3 includes a filter mesh 30 and a first fixing member 31 provided at the first end of the filter mesh 30, and the first fixing member 31 is fixed in the mounting groove 20 to rotate with the reel 2 and drive the filter mesh 30 to move.

[0032] The first fixing member 31 includes a fixing member body and plug-in portions at both ends of the fixing member body, so as to be inserted into the plug-in slots at both ends of the installation slot 20 of the reel 2 , thereby fixing the first fixing member 31 and the reel 2 in connection.

[0033] like Figure 1 As shown, the mounting frame 1 is provided with a guide groove 11 communicating with the accommodating cavity 10 . The guide groove 11 is provided corresponding to the filter mesh element 3 for guiding the movement of the filter mesh element 3 .

[0034] Specifically, the mounting frame 1 includes a first mounting portion 101 and a second mounting portion 102 disposed opposite each other. The first mounting portion 101 and the second mounting portion 102 are assembled together by means of snaps and screws to form a receiving cavity 10 and a guide groove 11 on the mounting frame 1. The arrangement of the first mounting portion 101 and the second mounting portion 102 facilitates the installation of the reel 2 and the like.

[0035] Preferably, there are two guide grooves 11 , which are respectively arranged corresponding to the opposite sides of the filter mesh 3 , so that the opposite sides of the flattened portion of the filter mesh 3 are respectively located in the two guide grooves 11 .

[0036] Specifically, the extension direction of the two guide grooves 11 is parallel to the movement direction of the filter mesh 3, so that the opposite sides of the filter mesh 3 move along the corresponding guide grooves 11, thereby guiding the movement of the filter mesh 3 and supporting the filter mesh 3 to prevent the filter mesh 3 from deformation.

[0037] like Figure 1 and Figure 2 As shown, an elastic member is provided in the guide groove 11, the first end of the elastic member is connected to the second end of the filter mesh member 3, and the second end of the elastic member is connected to the end of the guide groove 11 away from the reel 2, so as to assist in pulling the second end of the filter mesh member 3 away from the reel 2 when the reel 2 drives the filter mesh member 3 to gradually flatten on the mounting frame 1.

[0038] Preferably, the elastic member is a tension spring. An elastic member is respectively disposed in the two guide grooves 11 , and the two elastic members are respectively connected to opposite ends of the filter mesh member 3 .

[0039] like Figure 1 、 Figure 2 and Figure 4 As shown, the filter element 3 includes a filter 30 and a second fixing member 32 provided at the second end of the filter 30 . The second fixing member 32 is connected to the first end of the elastic member at a side away from the filter 30 .

[0040] The filter element 3 is integrally connected to a first fixing member 31 and a second fixing member 32 at both ends of the filter element 3 along the direction of movement. The first fixing member 31 and the second fixing member 32 are identical in shape and size, and each includes a fixing member body and plug-in portions at both ends of the fixing member body. The first fixing member 31 is mounted within the mounting slot 20 of the reel 2. Screws are screwed into the corresponding plug-in portions of the first fixing member 31 at both ends of the reel 2 to further secure the connection between the reel 2 and the first fixing member 31. One side of the second fixing member 32 is connected to the filter element 30. The plug-in portions at both ends of the other side of the second fixing member 32 are inserted into corresponding guide slots 11 and connected to elastic members in the corresponding guide slots 11. This allows the elastic members to assist in pulling the second end of the filter element 3 away from the reel 2 through the second fixing member 32.

[0041] like Figure 2 As shown, the filter mechanism also includes a cleaning brush 4, which is arranged on the mounting frame 1 and located at one end of the mounting frame 1 close to the reel 2. The bristles of the cleaning brush 4 are in contact with the mesh surface of the filter mesh 3 to clean the filter mesh 3 when the filter mesh 3 moves relative to the mounting frame 1.

[0042] The present invention provides a cleaning brush 4 at one end of the mounting frame 1 close to the reel 2, so that when the reel 2 drives the filter mesh 3 to move, the dust on the filter mesh 3 is cleaned by the friction between the cleaning brush 4 and the filter mesh 3, thereby achieving the purpose of automatic dust removal, reducing the process of manual disassembly and cleaning of the filter mesh 3, and solving the problem of the inconvenience of manual disassembly and cleaning of the filter mesh in the air-conditioning cabinet with reversible air outlet in the prior art.

[0043] Specifically, the cleaning brush 4 is located at one end of the filter element 3 close to the reel 2 and is located on a side of the reel 2 close to the first opening in the accommodating chamber 10 .

[0044] The cleaning brush 4 is rotatably mounted on the mounting frame 1 around its own axis. The driving component 5 is drivingly connected to the cleaning brush 4 to drive the cleaning brush 4 to rotate around its own axis. The output shaft of the driving component 5 is coaxially connected to the reel 2, and a driving wheel is provided on the output shaft of the driving component 5. A driven wheel meshing with the driving wheel is provided at one end of the cleaning brush 4. The driving component 5 drives the driven wheel to rotate through the driving wheel to drive the cleaning brush 4 to rotate, thereby causing the reel 2 and the cleaning brush 4 to rotate in opposite directions relative to each other.

[0045] like Figure 1 and Figure 2 As shown, a dust collecting box 6 is provided at the bottom of the accommodating cavity 10 for collecting dust on the filter mesh 3 .

[0046] Specifically, the accommodating chamber 10 has a second opening portion that connects the accommodating chamber 10 and the dust collecting box 6. The dust collecting box 6 is a box body structure with an upper opening. The accommodating chamber 10 is connected to the dust collecting box 6. The dust collecting box 6 is located below the cleaning brush 4 in the accommodating chamber 10 to collect dust and foreign matter brushed off by the cleaning brush 4.

[0047] The present invention also provides an air conditioner, comprising a filter mechanism, wherein the filter mechanism is the above-mentioned filter mechanism.

[0048] Specifically, the air conditioner of the present invention is a cabinet air conditioner, and the filter mechanism is arranged in the air duct of the cabinet air conditioner near the upwind outlet.

[0049] like Figure 5 As shown, the air conditioner includes an upper air vent assembly, which is composed of a top cover 100, a bracket 200, and a filter mechanism 300. The upper air vent is located at the opening of the top cover 100, and a portion of the air duct is formed between the upper air vent and the filter mechanism 300. When the upper air vent is used for air discharge, the filter mechanism is opened, allowing air inside the casing to be discharged through the upper air vent to the outside of the casing. When the upper air vent is used for air intake, the filter mechanism is closed, allowing air outside the casing to enter the casing through the upper air vent and through the filter element of the filter mechanism.

[0050] The working process of the filter mechanism of the present invention is as follows:

[0051] (1) When the upwind port is the air outlet, the controller sends a signal to drive the motor to drive the reel 2 to rotate, and overcome the resistance of the elastic member at the second end of the filter mesh 3, and gradually wind the filter mesh 3 on the reel 2. When the motor rotates to a certain angle and stops rotating, the filter mesh 3 completes the storage process, and the filter mechanism is opened; when the upwind port is the air inlet, the motor receives the control signal again to rotate in the reverse direction, and pushes the reel 2 to rotate in the reverse direction. At the same time, the elastic member at the second end of the filter mesh 3 also applies a pulling force to the filter mesh 3, so that the filter mesh 3 moves along the guide groove 11 on the mounting frame 1, and finally reaches the predetermined position, and returns to the flattened state, so that the filter mechanism is closed.

[0052] (2) When the controller starts the cleaning program, it sends a signal to drive the motor to drive the reel 2 to rotate, and overcome the resistance of the elastic member at the second end of the filter mesh 3, and gradually wind the filter mesh 3 onto the reel 2. In the process of the filter mesh 3 moving from the mounting frame 1 to the reel 2, the cleaning brush 4 and the filter mesh 3 will move relative to each other to clean the dust and foreign matter on the filter mesh 3, and the dust box 6 at the bottom of the accommodating chamber 10 will collect the cleaned dust and foreign matter; then, the motor receives the control signal again to rotate in the reverse direction, and pushes the reel 2 to rotate in the reverse direction. At the same time, the elastic member at the second end of the filter mesh 3 will also give the filter mesh 3 a pulling force, and together the filter mesh 3 will be flattened on the mounting frame 1 along the guide groove 11.

[0053] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0054] The filter mechanism of the present invention comprises a reel 2 disposed within a housing 10 at one end of a mounting frame 1 containing a filter element 3. One end of the filter element 3 is fixedly connected to the reel 2, so that the filter element 3 can be wound around the reel 2 or flattened onto the mounting frame 1 by rotation of the reel 2. The filter mechanism is disposed in the air duct of an air conditioner with vertically reversible airflow, near the upper air outlet. When the upper air outlet is the air outlet, the filter mechanism is in an open position, with the filter element 3 wound around the reel 2, reducing wind resistance of the filter mechanism and achieving high airflow and better cooling performance. When the upper air outlet is the air inlet, the filter mechanism is in a closed position, with the filter element 3 flattened on the mounting frame 1, filtering airflow entering the air conditioner to prevent the ingress of dust and foreign matter. This solves the problem of conventional cabinet air conditioners with vertically reversible airflow, which suffers from the inability to switch the filter between open and closed positions.

[0055] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
