Description

Technical Field

[0001] This invention relates to the field of filtration devices, and more specifically, to a filtration device and an air conditioner. Background Technology

[0002] With rapid economic development, the communications, mobile internet, and big data industries are also growing rapidly, leading to increasingly stringent requirements for air conditioning in data centers. Air-cooled data center air conditioners, a type of air conditioning system, are primarily used in computer rooms, data centers, and electronic equipment rooms to provide cooling, heating, air circulation, and humidity control, ensuring the environment meets the normal operating requirements of the equipment. The coarse filter in a data center air conditioner serves as the first line of defense in the air filtration system. It intercepts large particulate pollutants such as dust, hair, and fibers from the air, preventing dust accumulation on critical components like evaporators and fans, reducing the risk of wear and blockage, protecting the air conditioning equipment, and extending its lifespan. However, due to its cleaning function, the coarse filter needs to be cleaned or replaced regularly; otherwise, it can become a source of pollution for the air conditioner.

[0003] There is an air filter for air conditioners that uses a vibration device to control the dust collection box to shake, thereby causing dust or particulate matter to fall off and achieve a dust removal and filtration effect. However, since the dust collection position of the dust collection box is the same as the working position, the dust removal process will affect the normal operation of the air conditioner. Summary of the Invention

[0004] The first objective of this invention is to provide a filtration device that can remove dust from a filter screen without affecting the normal operation of the equipment.

[0005] A second objective of the present invention is to provide an air conditioner employing the above-described filtration device.

[0006] To achieve the aforementioned first objective, the present invention provides a filtration device, comprising a first filter component, a second filter component, a guide rail assembly, a drive assembly, and a vibration component. The guide rail assembly includes a first guide rail and a second guide rail arranged along a first horizontal direction, both extending along a second horizontal direction. The first filter component is slidably engaged with the first guide rail, and the second filter component is slidably engaged with the second guide rail. The first guide rail has a first filtration position and a first cleaning position arranged along the second horizontal direction, and the second guide rail has a second filtration position and a second cleaning position arranged along the second horizontal direction. The first filtration position and the second filtration position are opposite to each other in the first horizontal direction, and the first cleaning position and the second cleaning position are opposite to each other in the first horizontal direction. The drive assembly drives the first filter component to move between the first filtration position and the first cleaning position, and drives the second filter component to move between the second filtration position and the second cleaning position. The vibration component is disposed at one end of the guide rail assembly near the first cleaning position and the second cleaning position.

[0007] As can be seen from the above scheme, after the dust cleaning function is activated, if the first filter component is in the first filtration position and the second filter component is in the second clean position, then the first filter component, acting as a filter at the air conditioner inlet, is a dirty filter component, while the second filter component is a clean filter component. The drive assembly drives the first filter component from the first filtration position to the first clean position, and the drive assembly also drives the second filter component from the second clean position to the second filtration position. The vibration component operates and causes the dirty filter component to vibrate, resulting in high-frequency micro-vibration of the contaminated first filter component, shaking off the attached dust, which then falls off due to gravity. This achieves the cleaning function of the first filter component. If the first filter component is in the first clean position and the second filter component is in the second filtration position, then the first filter component, acting as a filter at the air conditioner inlet, is a dirty filter component. The drive assembly drives the first filter component from the first clean position to the first filtration position, and the drive assembly also drives the second filter component from the second filtration position to the second clean position. The vibration component operates to clean the second filter component. This allows for the replacement of dirty and clean filter components without affecting the normal operation of air conditioning and other equipment while cleaning the filter screen.

[0008] A preferred embodiment is that there are two guide rail assemblies, one of which is located at the top of the first filter component and the other at the bottom of the first filter component; the drive assembly is disposed on the top guide rail assembly and the vibration assembly is disposed on the bottom guide rail assembly.

[0009] As can be seen, the top and bottom guide rails work together to guide the filter components. Meanwhile, the drive component is located on the upper guide rail to prevent dust from falling into the drive component and affecting its function. The vibration component is located on the lower guide rail to better achieve vibration cleaning of the filter components.

[0010] A further embodiment includes a drive assembly comprising a drive member, a drive wheel, a driven wheel, and a transmission member; the drive wheel and the driven wheel are arranged at both ends of the guide rail assembly along a second horizontal direction, with the central axes of both the drive wheel and the driven wheel extending vertically; the transmission member surrounds the drive wheel and the driven wheel, and includes a first transmission section and a second transmission section arranged parallel to each other along a first horizontal direction, a first filter component connected to the first transmission section, and a second filter component connected to the second transmission section; the drive member drives the drive wheel to rotate, the drive wheel drives the transmission member to move, and the transmission member drives the first filter component and the second filter component to move.

[0011] Therefore, by driving the drive wheel to rotate, the drive wheel drives the transmission component to move, thereby enabling the transmission component to move the first filter component and the second filter component. At the same time, by rotating the drive component in both directions, the first filter component and the second filter component alternate between the cleaning position and the filtering position, ensuring that the clean filter component can work normally when the dirty filter component is being cleaned.

[0012] A further option is to include a motor as the driving component and a conveyor belt or conveyor chain as the transmission component.

[0013] It can be seen that the filter components are driven by a motor-driven conveyor belt or chain that moves around the driving wheel and driven wheel. The structure is simple and can transport the components forward smoothly.

[0014] A preferred embodiment is that a first dust collection hole is provided at the first cleaning position of the first guide rail at the bottom, and a second dust collection hole is provided at the second cleaning position of the second guide rail at the bottom; a dust collection box is also provided on the lower side of the guide rail assembly at the bottom, and both the first dust collection hole and the second dust collection hole are connected to the dust collection box.

[0015] As can be seen, by setting the first dust collection hole and the second dust collection hole, when the dust in the filter component is shaken off, the dust falls into the dust collection box below through the dust collection hole, thereby achieving dust collection.

[0016] A further option is that there are two or more first dust collection holes, each arranged along the extension direction of the corresponding first guide rail; and / or there are two or more second dust collection holes, each arranged along the extension direction of the corresponding second guide rail.

[0017] Therefore, there can be multiple dust collection holes, which are arranged along the extension direction of the corresponding guide rail. This allows the dust to fall smoothly into the dust collection box below, while also ensuring that the movement of the filter components within the guide rail is not affected.

[0018] In a preferred embodiment, the filtration device further includes a sensor for detecting the position of the first filtration element.

[0019] Therefore, by setting up the sensor, the position of the first filter component can be detected, and the controller can control the motor to rotate forward or backward through the position signal of the first filter component. For example, when the first filter component is detected to be in the first filtering position, the motor rotates forward to drive the first filter component to move to the first cleaning position; when the first filter component is detected to be in the first cleaning position, the motor rotates backward to drive the first filter component to move to the first filtering position.

[0020] A further embodiment involves the following steps: when the sensor detects that the first filter element is in the first filtering position, the drive assembly drives the first filter element to move from the first filtering position to the first cleaning position, and the drive assembly also drives the second filter element to move from the second cleaning position to the second filtering position, while the vibration component cleans the first filter element; when the sensor detects that the first filter element is in the first cleaning position, the drive assembly drives the first filter element to move from the first cleaning position to the first filtering position, and the drive assembly also drives the second filter element to move from the second filtering position to the second cleaning position, while the vibration component cleans the second filter element.

[0021] To achieve the second objective described above, the present invention provides an air conditioner including the aforementioned filtration device.

[0022] In a preferred embodiment, the air conditioner further includes an air conditioner body and a door panel, with both the first and second filter components located on the inner side of the door panel. An air inlet is provided through the door panel along a first horizontal direction, with the first and second filter positions positioned opposite to the air inlet in the first horizontal direction, and the first and second cleaning positions staggered from the air inlet in the first horizontal direction.

[0023] Therefore, by placing the filter components on the inside of the door panel, dust can be prevented from settling on the clean filter components when they are located on the outside of the air conditioner, thus avoiding affecting the filtration effect. Attached Figure Description

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0036] Various exemplary embodiments of the invention will now be described in detail with reference to the accompanying drawings.

It should also be understood that terms defined in general dictionaries should be interpreted as having the meaning consistent with their meaning in the context of the relevant art, and not as having an idealized or highly formalized meaning, unless expressly defined herein.

[0040] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0041] See Figure 1 In this embodiment, the air conditioner is a wind-cooled computer room air conditioner. The air conditioner includes an air conditioner body 1, a filter device 2, and a door panel 3. The door panel 3 is located on the air inlet side of the air conditioner body 1.

[0042] See Figures 2 to 7 The filter device 2 includes a first filter component 4, a second filter component 5, a guide rail assembly 6, a drive assembly 7, and a vibration component 8.

[0043] An air inlet is provided along the first horizontal direction on the door panel 3. The first filter element 4, the second filter element 5, and the guide rail assembly 6 are all located on the inside of the door panel 3. By placing the filter elements on the inside of the door panel 3, dust accumulation on the clean filter elements, which would affect the filtration effect, is avoided when they are located on the outside of the air conditioner. Both the first filter element 4 and the second filter element 5 are coarse filters. The filter element located at the air inlet serves as the first line of defense in the air conditioning system. When outside air enters the air conditioner in the computer room, it first passes through this filter element to intercept large particulate pollutants in the air.

[0044] The guide rail assembly 6 includes a first guide rail 61 and a second guide rail 62 arranged along a first horizontal direction. The first guide rail 61 and the second guide rail 62 are integral structures and both are groove-shaped. Both the first guide rail 61 and the second guide rail 62 extend along a second horizontal direction. The first filter component 4 is slidably engaged with the first guide rail 61, and the second filter component 5 is slidably engaged with the second guide rail 62. In this embodiment, the first horizontal direction is the thickness direction of the door panel 3, and the second horizontal direction is the width direction of the door panel 3.

[0045] The first guide rail 61 has a first filter position 611 and a first cleaning position 612 arranged along the second horizontal direction. The second guide rail 62 has a second filter position 621 and a second cleaning position 622 arranged along the second horizontal direction. The first filter position 611 and the second filter position 621 are both arranged opposite to the air inlet in the first horizontal direction. The first cleaning position 612 and the second cleaning position 622 are arranged opposite to each other in the first horizontal direction and are offset from the air inlet in the first horizontal direction. The drive assembly 7 drives the first filter component 4 to move between the first filter position 611 and the first cleaning position 612, and drives the second filter component 5 to move between the second filter position 621 and the second cleaning position 622. The vibration component 8 is disposed at one end of the guide rail assembly 6 near the first cleaning position 612. The vibration component 8 can drive the first filter component 4 located at the first cleaning position 612 to vibrate up and down or back and forth, and can also drive the second filter component 5 located at the second cleaning position 622 to vibrate up and down or back and forth, shaking off the dust attached to it, thereby cleaning the filter components.

[0046] There are two guide rail assemblies 6, one located at the top of the first filter component 4 and the other at the bottom. A drive assembly 7 is mounted on the top guide rail assembly 6, and a vibration component 8 is mounted on the bottom guide rail assembly 6. The top and bottom guide rail assemblies 6 work together to guide the filter component. The drive assembly 7, mounted on the top guide rail assembly 6, prevents dust from falling into it and affecting its function. The vibration component 8, a vibrating motor, is mounted on the bottom guide rail assembly 6 to better clean the filter component through vibration.

[0047] See Figure 8 , Figure 10 and Figure 11The drive assembly 7 includes a drive member 71, a drive wheel 72, a driven wheel 73, and a transmission member 74. The drive member 71 includes a motor, and the transmission member 74 includes a conveyor belt or a conveyor chain. The drive wheel 72 and the driven wheel 73 are arranged at both ends of the guide rail assembly 6 along a second horizontal direction. The central axis of both the drive wheel 72 and the driven wheel 73 extends vertically. The transmission member 74 surrounds the drive wheel 72 and the driven wheel 73. The transmission member 74 includes a first transmission section 741 and a second transmission section 742 that are parallel to each other and arranged along a first horizontal direction. A first filter component 4 is connected to the first transmission section 741, and a second filter component 5 is connected to the second transmission section 742. The drive member 71 drives the drive wheel 72 to rotate, the drive wheel 72 drives the transmission member 74 to move, and the transmission member 74 drives the first filter component 4 and the second filter component 5 to move. The drive member 71 drives the drive wheel 72 to rotate, and the drive wheel 72 drives the transmission member 74 to move, thereby enabling the transmission member 74 to drive the first filter component 4 and the second filter component 5 to move. At the same time, the forward and reverse rotation of the drive member 71 enables the first filter component 4 and the second filter component 5 to alternate between the cleaning position and the filtering position, ensuring that the clean filter component can work normally when the dirty filter component is being cleaned.

[0048] See Figures 7 to 9 A first dust collection hole 613 is provided on the first cleaning position 612 of the first guide rail 61 at the bottom, and a second dust collection hole 623 is provided on the second cleaning position 622 of the second guide rail 62 at the bottom. A dust collection box 9 is also provided on the lower side of the guide rail assembly 6 at the bottom. Both the first dust collection hole 613 and the second dust collection hole 623 are connected to the dust collection box 9. With the arrangement of the first dust collection hole 613 and the second dust collection hole 623, when the dust of the filter component is shaken off, the dust falls into the dust collection box 9 below through the dust collection hole, thereby realizing the collection of dust.

[0049] There are two or more first dust collection holes 613, each arranged along the extension direction of the corresponding first guide rail 61. There are also two or more second dust collection holes 623, each arranged along the extension direction of the corresponding second guide rail 62. Multiple dust collection holes can be arranged along the extension direction of the corresponding guide rails. This ensures that dust falls smoothly into the lower dust collection box 9 without affecting the movement of the filter components within the guide rails.

[0050] The filtering device 2 also includes a sensor 10 and a timer 11. The sensor 10 is a distance sensor, fixed to one end of the first guide rail 61 near the first filtering position 611, used to detect the distance between itself and the first filtering component 4, that is, to detect the position of the first filtering component 4. The timer 11 is located on the same side of the filtering device 2 as the vibration component 8 and is positioned on the top guide rail assembly 6 away from the sensor 10, used to control the running time of the vibration motor, with the time value set to a preset fixed value c. Therefore, by setting the sensor 10, the position of the first filtering component 4 can be detected, and the controller can control the motor to rotate forward or backward based on the position signal of the first filtering component 4.

[0051] When the self-cleaning function of the coarse filter of the computer room air conditioner is manually activated, when the sensor 10 detects a distance 'a' between itself and the first filter element 4, i.e., the first filter element 4 is at the first filtration position 611, the motor rotates forward and drives the transmission component 74 to rotate clockwise. The transmission component 74 moves the first filter element 4 to the right, from the first filtration position 611 to the first cleaning position 612. Simultaneously, the transmission component 74 moves the second filter element 5 to the left, from the second cleaning position 622 to the second filtration position 621, thus replacing the old coarse filter. At the same time, the sensor 10 monitors the position of the first filter element 4 in real time. When the distance 'b' between itself and the first filter element 4 is detected, the motor stops running, and the vibration component 8 operates, generating high-frequency micro-vibrations. This causes the first filter element 4 to vibrate, shaking off large particles of contaminants and dislodging them into the dust collection box 9, thus cleaning the first filter element 4. Simultaneously, the timer 11 starts timing. When the time value equals 'c', the vibration motor stops running. At this point, the self-cleaning function of the coarse filter ends.

[0052] When sensor 10 detects a distance of 'b' between itself and the first filter element 4, i.e., when the first filter element 4 is in the first cleaning position 612, the motor reverses and drives the conveyor 74 to rotate counterclockwise. The conveyor 74 moves the first filter element 4 to the left, from the first cleaning position 612 to the first filtration position 611. Simultaneously, the conveyor 74 moves the second filter element 5 to the right, from the second filtration position 621 to the second cleaning position 622, thus replacing the old coarse filter. Meanwhile, sensor 10 continuously monitors the position of the first filter element 4. When the detected distance 'a' is reached, the motor stops, and the vibration component 8 activates, generating high-frequency micro-vibrations that vibrate the second filter element 5, shaking off large particles of contaminants and depositing them into the dust collection box 9, thus cleaning the second filter element 5. Simultaneously, timer 11 starts counting, and when the time value equals 'c', the vibration motor stops. At this point, the self-cleaning function of the coarse filter ends.

[0053] As can be seen from the above, after the dust cleaning function is activated, if the first filter element is in the first filtration position and the second filter element is in the second clean position, then the first filter element, acting as a filter at the air conditioner inlet, is a dirty filter element, while the second filter element is a clean filter element. The drive assembly moves the first filter element from the first filtration position to the first clean position, and simultaneously moves the second filter element from the second clean position to the second filtration position. The vibration component operates and causes the dirty filter element to vibrate, resulting in high-frequency micro-vibrations that shake off the attached dust, allowing it to fall off due to gravity. This achieves the cleaning function of the first filter element. If the first filter element is in the first clean position and the second filter element is in the second filtration position, then the first filter element, acting as a filter at the air conditioner inlet, is a dirty filter element. The drive assembly moves the first filter element from the first clean position to the first filtration position, and simultaneously moves the second filter element from the second filtration position to the second clean position. The vibration component then cleans the second filter element. This allows for the replacement of dirty and clean filter components without affecting the normal operation of air conditioning and other equipment while cleaning the filter screen.

[0054] Finally, it should be emphasized that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
