[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present 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.

[0028] like Figures 1 to 8 As shown, the present invention provides a filter mechanism, comprising: a support frame 1; a filter assembly 2, the filter assembly 2 comprising a first filter portion 21 and a second filter portion 22 for jointly shielding an air duct; the first filter portion 21 is rotatably arranged on the support frame 1 around a first predetermined axis, and the second filter portion 22 is rotatably arranged on the support frame 1 around a second predetermined axis, the first predetermined axis and the second predetermined axis are parallel to each other, and the rotation direction of the first filter portion 21 and the rotation direction of the second filter portion 22 are opposite to each other; a driving component 3, the driving component 3 is arranged on the support frame 1, and is respectively connected to the first filter portion 21 and the second filter portion 22 to drive the first filter portion 21 and the second filter portion 22 to rotate, so that the filter mechanism is opened or closed.

[0029] The filter mechanism of the present invention can use a driving component 3 to drive the first filter part 21 and the second filter part 22 of the filter mechanism for dust prevention in the air duct of the air conditioner to switch between the open and closed states, so as to achieve efficient control of the filter mechanism. Driven by the driving component 3, when the air duct is an air inlet channel, the filter mechanism is in a closed state to prevent dust from entering the air conditioner; when the air duct is an air outlet channel, the filter mechanism is in an open state to reduce the wind resistance of the filter mechanism and achieve a large air volume of air supply of the air conditioner. In this way, the problem that the filter cannot be switched between the open and closed modes in the cabinet with reversible air outlet in the prior art is solved.

[0030] like Figure 2 As shown, the first filter part 21 and the second filter part 22 both include: a mounting frame 23, which is rotatably connected to the support frame 1; a filter screen 24, which is mounted on the mounting frame 23, and the mounting frame 23 has an escape space for avoiding part of the mesh of the filter screen 24 to allow air flow to pass through; a driving component 3 is drivingly connected to the mounting frame 23 to drive the mounting frame 23 to rotate synchronously.

[0031] Specifically, the mounting frame 23 is a rectangular frame structure composed of a plurality of mutually perpendicular or parallel strip beam structures, and the avoidance space is the space formed by the rectangular frame structure, so that the airflow passes through the mesh body of the filter 24 located in the avoidance space for filtering; each strip beam structure is provided with a hollow groove body in the thickness direction of the mounting frame 23 to enclose a disassembly and assembly groove 231 for accommodating the filter 24.

[0032] Specifically, the filter assembly 2 also includes a rotating shaft 25, which is passed through the mounting frame 23, and both ends of the rotating shaft 25 are respectively connected to the support frame 1. The driving component 3 is drivingly connected to the rotating shaft 25 to drive the mounting frame 23 to rotate relative to the support frame 1 through the rotating shaft 25.

[0033] The first filter part 21 and the second filter part 22 of the present invention are symmetrically arranged on the support frame 1 , and one end of the first filter part 21 and the second filter part 22 having the rotating shaft 25 are both located near the middle of the support frame 1 .

[0034] When the first filter part 21 and the second filter part 22 move away from one end of the rotating shaft 25 toward the middle of the support frame 1, the filter mechanism opens; when the first filter part 21 and the second filter part 22 move away from one end of the rotating shaft 25 toward the opposite sides of the support frame 1, the filter mechanism closes.

[0035] Specifically, the first filter part 21 and the second filter part 22 are assembled with the support frame 1 by using pins.

[0036] Specifically, the first driven wheel 42 is fixed on the rotating shaft 25 of the first filter portion 21 , and the second driven wheel 44 is fixed on the rotating shaft 25 of the second filter portion 22 .

[0037] like Figure 7 As shown, the filter mechanism also includes a transmission assembly 4, which includes: a driving wheel 41, the driving component 3 is drivingly connected to the driving wheel 41; a first driven wheel 42, the first driven wheel 42 is drivingly connected to the first filter part 21 and is coaxially arranged with the first predetermined axis, and the first driven wheel 42 is meshed with the driving wheel 41; an intermediate driven wheel 43 and a second driven wheel 44, the second driven wheel 44 is drivingly connected to the second filter part 22 and is coaxially arranged with the second predetermined axis, and the intermediate driven wheel 43 is respectively meshed with the second driven wheel 44 and the driving wheel 41 to transmit the power of the driving wheel 41 to the second driven wheel 44.

[0038] A transmission assembly 4 is arranged between the driving component 3 and the filter screen assembly 2, the output shaft of the driving component 3 is fixedly connected to the driving wheel 41, the first driven wheel 42 is fixedly connected to the first filter portion 21, the first driven wheel 42 and the driving wheel 41 are meshed with each other, so that the rotation direction of the first driven wheel 42 is opposite to the rotation direction of the driving wheel 41; the second driven wheel 44 is fixedly connected to the second filter portion 22, the driving wheel 41 is transmission-connected to the second driven wheel 44 through the intermediate driven wheel 43, so that the rotation direction of the second driven wheel 44 is the same as the rotation direction of the driving wheel 41.

[0039] In this way, the rotation direction of the first driven wheel 42 and the rotation direction of the second driven wheel 44 are opposite to each other, so that the first filter part 21 and the second filter part 22 are relatively closed or separated, thereby realizing the opening or closing action of the filter mechanism in opposite rotation directions by a driving component, realizing efficient control of the filter mechanism and reducing the manufacturing cost of the filter mechanism.

[0040] like Figures 1 to 3As shown, the filter mechanism is in a closed state. When the filter mechanism switches to an open state, the output shaft of the driving component 3 drives the driving wheel 41 to rotate clockwise, the first driven wheel 42 drives the first filter part 21 to rotate counterclockwise, the middle driven wheel 43 rotates counterclockwise, and the second driven wheel 44 drives the second filter part 22 to rotate clockwise.

[0041] like Figures 4 to 6 As shown, the filter mechanism is in an open state. When the filter mechanism switches to a closed state, the output shaft of the driving component 3 drives the driving wheel 41 to rotate counterclockwise, the first driven wheel 42 drives the first filter part 21 to rotate clockwise, the middle driven wheel 43 rotates clockwise, and the second driven wheel 44 drives the second filter part 22 to rotate counterclockwise.

[0042] Among them, clockwise rotation means Figure 7 The arrow B in the figure indicates the direction of rotation.

[0043] Preferably, to ensure sufficient transmission force between the driving component 3 and the filter assembly 2, the transmission ratio between every two adjacent gears in the plurality of gears of the transmission assembly 4 is 1. In actual use, the transmission ratio can also be adjusted according to actual conditions.

[0044] like Figure 8 As shown, the support frame 1 includes a limiting portion 11 for stopping the rotation of the first filter portion 21 and the second filter portion 22 .

[0045] Specifically, the limiting portion 11 includes two groups of limiting ribs, and the two groups of limiting ribs are respectively arranged on two opposite sides of the support frame 1.

[0046] A set of limiting ribs are respectively arranged on opposite sides of the support frame 1 to stop the ends of the first filter part 21 and the second filter part 22 away from their respective rotation axes 25. When the first filter part 21 and the second filter part 22 rotate to contact with the corresponding limiting ribs, they cannot continue to rotate and will not rotate excessively. In this way, the controller can receive feedback that the filter mechanism has moved into place, reducing the number of micro switches.

[0047] Specifically, the support frame 1 has an escape opening, and the escape opening is used to escape a part of the filter net 24 of the first filter part 21 and a part of the filter net 24 of the second filter part 22 to allow air flow to pass through.

[0048] Specifically, the support frame 1 is a rectangular frame structure, and the avoidance opening is the space formed by the rectangular frame structure. When the filter mechanism is closed, the airflow passes through the mesh of the filter 24 located at the avoidance opening for filtering; when the filter mechanism is opened, the airflow passes through the avoidance opening (without passing through the filter 24) to the next position.

[0049] Optionally, the driving component 3 includes a first driving component and a second driving component, the first driving component is drivingly connected to the first filter part 21, and the second driving component is drivingly connected to the second filter part 22, so as to drive the first filter part 21 and the second filter part 22 to rotate relative to each other, so that the filter mechanism is opened or closed.

[0050] The filter mechanism of the present invention can also use two driving components 3 to respectively drive the first filter part 21 and the second filter part 22 of the filter mechanism to rotate. The controller simultaneously sends signals to the two driving components 3 so that the two driving components 3 that receive the signals respectively drive the corresponding filter parts to rotate, thereby realizing the opening or closing of the filter mechanism.

[0051] Specifically, the driving component 3 is a motor.

[0052] The present invention also provides an air conditioner, comprising: a casing, in which an air duct connected to the outside of the casing is arranged; a filter mechanism, which is the above-mentioned filter mechanism, and the filter mechanism is arranged in the air duct; when the air duct is used for air outlet, the filter mechanism is opened to allow the air in the casing to be discharged to the outside of the casing through the air duct; when the air duct is used for air intake, the filter mechanism is closed to allow the air outside the casing to enter the casing through the air duct and through the filter of the filter mechanism.

[0053] The air conditioner of the present invention is an air conditioning cabinet with reversible air outlet up and down. The filter mechanism is located in the air duct of the air conditioning cabinet. The function of the filter 24 is to filter and dustproof the airflow entering the casing. The support frame 1 is installed in the casing of the air conditioning cabinet. The support frame 1 supports the filter assembly 2, the driving component 3 and the transmission assembly 4. The rotating shaft 25 of the filter assembly 2 is located in the middle position of the entire air duct, so that the filter assembly 2 can move to the opposite sides of the support frame 1 to close or move to the middle of the support frame 1 to open.

[0054] When the air duct is used as an air inlet channel, the controller sends a signal to drive the driving component 3 to rotate counterclockwise, so as to drive the driving wheel 41 to rotate counterclockwise, so that the first filter part 21 rotates clockwise, the second filter part 22 rotates counterclockwise, and the filter mechanism is switched to a closed state.

[0055] When the air duct is used as an air outlet channel, the controller sends a signal to drive the driving component 3 to rotate clockwise, so as to drive the driving wheel 41 to rotate clockwise, so that the first filter part 21 rotates counterclockwise, the second filter part 22 rotates clockwise, and the filter mechanism is switched to the open state.

[0056] Among them, the driving component 3 is a stepper motor, which is driven by a pulse current to make the stepper motor rotate a certain angle. Whenever the stepper motor receives a pulse signal from the controller, the stepper motor rotates a certain angle; to ensure that the filter assembly 2 rotates into place, when the controller is programmed, the stepper motor is controlled to rotate 5 to 10 degrees more. When the filter assembly 2 rotates to a predetermined position and contacts the limiting rib, the stepper motor continues to transmit driving force to the filter assembly 2, but the filter assembly 2 is stopped and cannot rotate, so as to ensure that the filter assembly 2 rotates into place while ensuring that it does not rotate excessively, and the controller can receive a feedback signal that the filter assembly 2 is rotated into place.

[0057] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0058] The filter mechanism of the present invention can use a driving component 3 to drive the first filter part 21 and the second filter part 22 of the filter mechanism for dust prevention in the air duct of the air conditioner to switch between the open and closed states, so as to achieve efficient control of the filter mechanism. Driven by the driving component 3, when the air duct is an air inlet channel, the filter mechanism is in a closed state to prevent dust from entering the air conditioner; when the air duct is an air outlet channel, the filter mechanism is in an open state to reduce the wind resistance of the filter mechanism and achieve a large air volume of air supply of the air conditioner. In this way, the problem that the filter cannot be switched between the open and closed modes in the cabinet with reversible air outlet in the prior art is solved.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
