Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a filter assembly and an air conditioner. Background Art

[0002] Air conditioners used in kitchens often draw in indoor air containing contaminants such as oil mist. This contaminant can adhere to the blower and heat exchanger, potentially reducing airflow performance. Furthermore, indoor microorganisms such as bacteria, mold, and viruses can use oil mist as a nutrient source to multiply within the air conditioner. Related technologies incorporate filters capable of collecting oil mist and other contaminants at the air inlet of the air conditioner to mitigate this problem.

[0003] However, the oil mist collection capacity of the filter provided by the related technology is limited, and the pressure loss increases after the filter collects oil mist and other stains, which will cause the air volume to decrease. Summary of the Invention

[0004] The problem solved by the present invention is to improve the problem of increased pressure loss after the filter collects oil mist and other stains, and to improve the problem of decreased air volume caused by the pressure loss.

[0005] To solve the above problems,

[0006] In a first aspect, the present invention provides an air conditioner, comprising:

[0007] A housing, wherein the housing is provided with an air inlet;

[0008] The filter screen is arranged in the shell and is located at the air inlet; the first end of the filter screen is close to the interior of the shell relative to the second end of the filter screen.

[0009] The filter screen arranged on the shell of the air conditioner in an embodiment of the present invention can collect stains such as oil mist, and the first end of the filter screen is close to the interior of the shell relative to the second end of the filter screen, so that the filter screen located at the air inlet is arranged in an inclined shape. The oil stains and other stains attached to the filter screen can flow down along the inclined filter screen to reduce the oil stains and other stains remaining on the filter screen, thereby improving the problem of increased pressure loss after the filter screen collects oil mist and other stains, and improving the problem of decreased air volume caused by pressure loss.

[0010] In an optional embodiment, the angle between the direction from the first end of the filter to the second end of the filter and a plane perpendicular to the air inlet direction of the air inlet is 1°-5°.

[0011] Properly tilting the filter can ensure that dirt such as oil attached to the filter can flow down the filter reliably, and can also ensure that the filter is easy to assemble on the housing.

[0012] In an optional embodiment, the filter screen includes at least one bend.

[0013] The bent portion can increase the contact area between the filter and dirt such as oil mist, thereby ensuring the oil mist collection capacity of the filter.

[0014] In an optional embodiment, the air conditioner further includes a support member, which is arranged on the air inlet side of the filter and is used to support the filter.

[0015] Supporting the filter with a support member can help maintain the shape of the filter, thereby ensuring the ability of the filter to collect stains such as oil mist, and ensuring that stains such as oil mist can reliably flow down the filter.

[0016] In an optional embodiment, the air conditioner further includes a frame, and the filter is arranged on the shell through the frame.

[0017] The filter is arranged on the housing through a frame, which facilitates the assembly and maintenance of the filter.

[0018] In an optional embodiment, the frame is provided with a groove, which is adjacent to the second end of the filter screen and is used to receive dirt dripping from the filter screen.

[0019] The grooves provided on the frame are used to receive the dirt dripping from the filter, so that the dirt such as oil collected by the filter can be discharged and recovered in a centralized manner, which is beneficial to the maintenance of the filter.

[0020] In an optional embodiment, the air conditioner further includes a drain pipe, which is disposed on the frame, adjacent to the second end of the filter screen, and is used to drain dirt dripping from the filter screen.

[0021] Use the drain pipe to drain away the oil and other stains flowing down from the filter, which can prevent the oil and other stains from entering the air conditioner and is beneficial to the maintenance of the filter.

[0022] In an optional embodiment, the air conditioner further includes an absorption portion, which is disposed at the second end of the filter and is used to absorb dirt dripping from the filter.

[0023] The absorption part absorbs the oil and other stains flowing down from the filter, making the collection and disposal of the oil and other stains easier, reducing the frequency of recycling and disposal of the oil and other stains, and facilitating the maintenance of the filter.

[0024] In an alternative embodiment, the absorbent portion has at least one of flame retardancy and oil stain curing properties.

[0025] The flame-retardant absorption part is not easy to catch fire even in a high temperature environment, thus ensuring safety; the oil-solidifying absorption part can prevent oil from dripping from the absorption part, thus ensuring a good oil absorption effect of the absorption part.

[0026] In an alternative embodiment, the filter mesh is made of non-woven fabric or metal fiber.

[0027] Non-woven fabrics or metal fibers have a good absorption effect on stains such as oil mist, and can allow stains such as oil to flow down the filter, preventing stains from accumulating on the filter.

[0028] In a second aspect, the present invention provides a filter assembly comprising:

[0029] A frame, wherein the frame is provided with ventilation holes;

[0030] The filter screen is arranged on the frame and located at the vent, and the first end of the filter screen is close to the air outlet side of the vent relative to the second end of the filter screen.

[0031] The filter assembly of the embodiment of the present invention can be used in an air conditioner to filter the gas entering the air conditioner, wherein the filter can collect stains such as oil mist in the gas, and the first end of the filter is close to the air outlet side of the vent relative to the second end of the filter, so that the filter is arranged in an inclined shape. The oil and other stains attached to the filter can flow down along the inclined filter to reduce the oil and other stains remaining on the filter, thereby improving the problem of increased pressure loss after the filter collects oil mist and other stains, and improving the problem of decreased air volume caused by pressure loss.

[0032] In an optional embodiment, the filter assembly further includes a support member, which is disposed on the air inlet side of the filter screen and is used to support the filter screen.

[0033] Supporting the filter with a support member can help maintain the shape of the filter, thereby ensuring the ability of the filter to collect stains such as oil mist, and ensuring that stains such as oil can reliably flow down the filter.

[0034] In an optional embodiment, the filter assembly further includes an absorption portion, which is disposed at the second end of the filter screen and is used to absorb dirt dripping from the filter screen.

[0035] The absorption part absorbs the oil and other stains flowing down from the filter, making the collection and disposal of the oil and other stains easier, reducing the frequency of recycling and disposal of the oil and other stains, and facilitating the maintenance of the filter.

[0036] In an optional embodiment, the frame is provided with a groove, which is adjacent to the second end of the filter screen and is used to receive dirt dripping from the filter screen.

[0037] The grooves provided on the frame are used to receive the dirt dripping from the filter, so as to facilitate the centralized discharge and recovery of the oil and other dirt collected by the filter, which is beneficial to the maintenance of the filter. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0045] Air conditioners provided by related technologies, such as floor-standing units, can be used in kitchens. However, kitchen air often contains contaminants such as oil mist, which can adhere to the blower or heat exchanger, easily reducing airflow performance. Furthermore, indoor microorganisms such as plankton, mold, and viruses can use oil mist and other contaminants as a nutrient source to multiply within the air conditioner. Related technologies incorporate filters capable of collecting oil mist and other contaminants at the air inlet of the air conditioner to mitigate the problem of oil mist entering the air conditioner.

[0046] However, in the process of collecting oil mist and other stains, the filter provided by the related technology continuously accumulates stains on the filter, resulting in limited oil mist collection capacity of the filter. In addition, after the filter collects oil mist and other stains, the accumulation causes the pressure loss to increase, which in turn causes the air volume to decrease.

[0047] This embodiment uses an inclined filter screen to allow the oil and other stains collected by the filter screen to flow down the filter screen, reducing the oil and other stains remaining on the filter screen. This improves the problem of increased pressure loss caused by the accumulation of oil mist and other stains on the filter screen after the filter screen collects the stains, and also improves the problem of decreased air volume caused by pressure loss.

[0048] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0049] Figure 1 This is a schematic diagram of the structure of the air conditioner 010 according to an embodiment of the present invention; Figure 1 This embodiment provides an air conditioner 010, which may refer to a floor-standing unit; of course, in other embodiments, the air conditioner 010 may also refer to an indoor unit.

[0050] The air conditioner 010 includes a shell 100, a blower 110, a heat exchanger 111 and a water collecting pan 112. The shell 100 is provided with an air inlet 101 and an air outlet 102. The blower 110, the heat exchanger 111 and the water collecting pan 112 are all arranged in the shell 100; the blower 110 is arranged adjacent to the air inlet 101, and is used to draw the gas outside the shell 100 into the shell 100, and make the gas entering the shell 100 flow to the heat exchanger 111; the heat exchanger 111 is used to exchange heat for the gas entering the shell 100; the water collecting pan 112 is used to receive condensed water dripping from the heat exchanger 111; the gas that has undergone heat exchange in the heat exchanger 111 can be output from the shell 100 through the air outlet 102.

[0051] The air inlet 101 of this embodiment is arranged at the bottom of the shell 100, that is, the air conditioner 010 of this embodiment is a bottom-inlet air conditioner; further, the air outlet 102 is arranged on the side of the shell 100, and the air inlet direction of the air inlet 101 and the air outlet direction of the air outlet 102 are distributed at an angle, and the angle can be 90°, 85°, 95°, etc., which is not specifically limited here.

[0052] It should be understood that in other embodiments, the air inlet 101 can be set on the side or top of the shell 100, which is not specifically limited here; the air outlet 102 can be set at the bottom or top of the shell 100, which is not specifically limited here.

[0053] In order to filter out oil mist and other contaminants in the air when the air conditioner 010 takes in air, the air conditioner 010 includes a filter component 200, and the filter component 200 includes a filter net 210. The filter net 210 is arranged on the shell 100, and the filter net 210 is located at the air inlet 101; the first end 211 of the filter net 210 is close to the interior of the shell 100 relative to the second end 212 of the filter net 210. In this way, when the air enters the shell 100 through the air inlet 101, it will be filtered by the filter 210 located at the air inlet 101, so that the oil mist and other stains in the air will adhere to the filter 210, and the oil mist and other stains in the air can be filtered; because the first end 211 of the filter 210 is close to the interior of the shell 100 relative to the second end 212 of the filter 210, the filter 210 located at the air inlet 101 is arranged in an inclined shape, and the oil and other stains attached to the filter 210 can flow down along the inclined filter 210, so as to reduce the oil and other stains remaining on the filter 210, thereby improving the problem of increased pressure loss after the filter 210 collects oil mist and other stains, and improving the problem of decreased air volume caused by pressure loss.

[0054] It should be noted that the material for preparing the filter screen 210 can be selected as needed, such as non-woven fabric or metal fiber, etc., which is not specifically limited here.

[0055] Please refer to Figure 1, the direction in which the first end 211 of the filter screen 210 points to the second end 212 of the filter screen 210 is angled with a plane perpendicular to the air inlet direction of the air inlet 101, and the angle between the two can be set as needed; in a preferred embodiment, the angle α between the direction in which the first end 211 of the filter screen 210 points to the second end 212 of the filter screen 210 and the plane perpendicular to the air inlet direction of the air inlet 101 is 1°-5°. Specifically, the angle α between the direction in which the first end 211 of the filter screen 210 points to the second end 212 of the filter screen 210 and the plane perpendicular to the air inlet direction of the air inlet 101 is 1°, 1.5°, 2°, 3°, 4°, 5°, etc.; appropriately tilting the filter screen 210 can ensure that stains such as oil attached to the filter screen 210 can reliably flow down the filter screen 210, and on the other hand, it can ensure that the filter screen 210 is easy to assemble on the housing 100. If the inclination angle of the filter 210 is too small, it may be detrimental to the flow of oil and dirt; if the inclination angle of the filter 210 is too large, a larger installation space needs to be reserved for the assembly of the filter 210, which makes it inconvenient to assemble the filter 210. For example: for a filter 210 with a length and width of 500mm×500mm, when the angle α between the direction in which the first end 211 of the filter 210 points to the second end 212 of the filter 210 and the plane perpendicular to the air inlet direction of the air inlet 101 is 1°, the height difference between the first end 211 of the filter 210 and the second end 212 of the filter 210 along the air inlet direction of the air inlet 101 is approximately 8.7mm, and the height of the installation space reserved for the filter 210 is approximately 15mm. Therefore, if the inclination angle of the filter 210 is too large, a larger installation space is required, which makes it inconvenient to install the filter 210.

[0056] Of course, in some embodiments, the angle α between the direction from the first end 211 of the filter 210 to the second end 212 of the filter 210 and the plane perpendicular to the air inlet direction of the air inlet 101 can also be 0.5°, 6°, etc., which is not specifically limited here.

[0057] It should be noted that the air inlet direction of the air inlet 101 of this embodiment is roughly vertical, that is, the air inlet direction of the air inlet 101 is perpendicular to the horizontal plane, and the direction of the first end 211 of the filter 210 pointing to the second end 212 of the filter 210 is distributed at an angle to the horizontal plane, and the angle is 1°-5°, so as to ensure that the stains can flow smoothly along the filter 210 and facilitate the assembly of the filter 210.

[0058] Figure 2 This is a schematic diagram of the structure of the filter 210 and the support member 230 in an embodiment of the present invention; Figure 2In order to increase the filtering area of ​​the filter 210, the filter 210 includes at least one bending portion 220. The bending portion 220 can increase the contact area between the filter 210 and stains such as oil mist, thereby ensuring the oil mist collection capacity of the filter 210.

[0059] The number of the bending portions 220 can be set as needed. In a preferred embodiment, the filter 210 includes multiple bending portions 220, and the multiple bending portions 220 are spliced ​​in sequence; in this way, the filter 210 has a sufficiently large filtering area to achieve a good filtering effect.

[0060] The filter 210 of this embodiment includes six bending portions 220 spliced ​​in sequence; in other embodiments, the number of bending portions 220 included in the filter 210 can also be one, two, three, four, eight, etc., which is not specifically limited here.

[0061] The specific structure of the bending portion 220 can be selected according to the needs, please refer to Figure 2 The bending portion 220 of this embodiment includes a first mesh plate 221 and a second mesh plate 222, and the first mesh plate 221 and the second mesh plate 222 are connected at an angle; further, one end of the second mesh plate 222 of one bending portion 220 that is not connected to the corresponding first mesh plate 221 is connected at an angle to one end of the first mesh plate 221 of the other bending portion 220 that is not connected to the corresponding second mesh plate 222, so that when viewed from the direction from the first end 211 of the filter mesh 210 to the second end 212 of the filter mesh 210, the cross-section of the filter mesh 210 is serrated.

[0062] Of course, in other embodiments, the bending portion 220 may also be an arc-shaped mesh plate, which is not specifically limited here.

[0063] It should be noted that the filter screen 210 of this embodiment has a serrated cross-section when viewed from the direction pointing from the first end 211 to the second end 212, which can ensure that the stains attached to the filter screen 210 can flow down reliably. In particular, the depression formed by the interconnection of the second mesh plate 222 of one bending portion 220 and the first mesh plate 221 of the other bending portion 220 can ensure that stains such as oil can flow down smoothly along the length direction of the depression.

[0064] Please continue to refer to Figure 2 In this embodiment, the filter assembly 200 further includes a support member 230, which is disposed on the air inlet side of the filter 210 and is used to support the filter 210. Using the support member 230 to support the filter 210 can help maintain the shape of the filter 210, thereby ensuring that the filter 210 can collect oil mist and other contaminants and ensure that the oil and other contaminants can reliably flow down the filter 210.

[0065] The structure of the support member 230 can be set as needed. In this embodiment, the support member 230 is a support net. In this way, the filter net 210 can be reliably supported while preventing the support member 230 from interfering with the air intake of the air inlet 101.

[0066] The support mesh includes a plurality of longitudinal ribs 231 and a plurality of transverse ribs 232, which are interlaced and connected to form a mesh structure. The longitudinal ribs 231 extend in the direction from the first end 211 of the filter 210 to the second end 212, and the transverse ribs 232 extend perpendicularly to the longitudinal ribs 231. The side of the first mesh panel 221 of each bend 220 not connected to the second mesh panel 222 of the bend 220, as well as the side of the second mesh panel 222 of each bend 220 not connected to the first mesh panel 221 of the bend 220, are supported by the corresponding longitudinal ribs 231. In this way, the support mesh can reliably support the filter 210 without interfering with air intake through the air inlet 101. It should be understood that in other embodiments, the first mesh panel 221 and the second mesh panel 222 may also be supported by the transverse ribs 232, which is not specifically limited here.

[0067] Of course, in other embodiments, the support member 230 may be a support rod or a support plate. When the support member 230 is a support plate, the support plate is provided with a through hole to prevent the support plate from interfering with the air intake of the air inlet 101 by using the through hole.

[0068] It should be noted that the supporting member 230 may be made of stainless steel or copper, etc., which is not specifically limited here.

[0069] Figure 3 This is a partial structural diagram of the filter assembly 200 in an embodiment of the present invention; please refer to Figure 1 and Figure 3 The filter assembly 200 also includes a frame 240, and the filter net 210 is set on the shell 100 through the frame 240; in this way, the filter net 210 can be assembled on the frame 240, and then the frame 240 assembled with the filter net 210 can be assembled on the shell 100 as a whole, so that the filter assembly 200 is modularly assembled on the shell 100, which facilitates the assembly of the filter assembly 200.

[0070] Furthermore, the frame 240 is provided with a vent 245, the filter 210 is arranged on the frame 240 and is located at the vent 245, and the first end 211 of the filter 210 is close to the air outlet side of the vent 245 relative to the second end 212 of the filter 210; the frame 240 is arranged at the air inlet 101 of the shell 100, and the vent 245 and the air inlet 101 overlap and are connected to ensure the reliability of the air intake of the air inlet 101, and ensure that the filter 210 is inclined at the air inlet 101 through the frame 240.

[0071] It should be noted that the filter 210 is set on the shell 100 through the frame 240. In addition to enabling the filter component 200 to be assembled in a modular manner on the shell 100 as a whole, when too much oil and other stains accumulate on the filter 210, making it difficult for the oil and other stains to flow down and affecting the air volume, the filter component 200 can be replaced as a whole with a new one to reduce the maintenance cost of the air conditioner 010.

[0072] The structure of the frame 240 can be set as needed. The frame 240 of this embodiment includes a first plate 241, a second plate 242, a third plate 243 and a fourth plate 244 which are connected end to end in sequence. The second plate 242 and the fourth plate 244 are both provided with ventilation holes 245. In this way, the filter net 210 can be set in the space surrounded by the first plate 241, the second plate 242, the third plate 243 and the fourth plate 244 to ensure the reliability of the overall assembly of the filter component 200 to the shell 100, and the ventilation holes 245 are used to ensure the reliability of the air intake of the air inlet 101.

[0073] Furthermore, the support member 230 is connected to the first plate 241 and the third plate 243 at the same time, and the support member 230 and the fourth plate 244 are distributed at an angle, and the angle between the two can be 1°-5°; the filter screen 210 is overlapped on the support member 230, and the filter screen 210 is opposite to the second plate 242 and the ventilation opening 245 opened on the fourth plate 244; the first plate 241 and the third plate 243 are both connected to the shell 100; in this way, the filter assembly 200 can be reliably set on the frame 240, and ensure that the filter screen 210 is set at an angle.

[0074] The frame 240 can be welded, that is, the connection method between the first plate 241, the second plate 242, the third plate 243 and the fourth plate 244 can be welding; of course, in other embodiments, the connection method between the first plate 241, the second plate 242, the third plate 243 and the fourth plate 244 can also be connected with fasteners such as bolts, etc., which is not specifically limited here.

[0075] The connection method between the frame 240 and the housing 100 can be selected as needed, for example, by snapping, bonding, or connecting with fasteners such as bolts, etc., which is not specifically limited here.

[0076] Figure 4 This is a schematic diagram of the structure of the filter assembly 200 according to an embodiment of the present invention; Figure 4 The frame 240 is provided with a groove 246 adjacent to the second end 212 of the filter 210 and configured to receive oil and other contaminants dripping from the filter 210. Thus, oil and other contaminants flowing down the filter 210 can be collected in the groove 246, facilitating the centralized discharge and recovery of the oil and other contaminants collected by the filter 210, thereby facilitating the maintenance of the filter 210.

[0077] It should be noted that the groove 246 provided on the frame 240 can be a depression formed by partially concavely forming the fourth plate 244 , as long as it can receive stains such as oil that flows down along the filter screen 210 .

[0078] Please continue to refer to Figure 4 The air conditioner 010 of this embodiment further includes a drain pipe 250, which is disposed on the frame 240. The drain pipe 250 is adjacent to the second end 212 of the filter 210 and is used to drain oil and other contaminants that drip from the filter 210. Using the drain pipe 250 to drain oil and other contaminants that flow from the filter 210 further prevents oil and other contaminants from entering the interior of the air conditioner 010. Furthermore, the oil can be drained without removing the filter 210, facilitating maintenance of the filter 210 and reducing the labor and cost of oil recovery and disposal.

[0079] Furthermore, a drain pipe 250 is provided at the bottom of the groove 246 and is in communication with the groove 246 , so that dirt such as oil accumulated in the groove 246 can be reliably discharged through the drain pipe 250 .

[0080] In other embodiments, the frame 240 is not provided with the groove 246 , and the oil and other dirt flowing down from the filter 210 can directly drip onto the fourth plate 244 and be discharged from the drain pipe 250 .

[0081] In other embodiments, the air conditioner 010 may not be provided with the drain pipe 250. After the air conditioner 010 has been used for a period of time, the filter assembly 200 may be directly disassembled to clean the oil and other stains accumulated in the groove 246.

[0082] It should be understood that in other embodiments, the filter assembly 200 may not include the frame 240, and the filter screen 210 may be directly connected to the housing 100. When the filter assembly 200 does not include the frame 240, the drain pipe 250 is also directly connected to the housing 100 and is used to drain oil and other dirt flowing down from the filter screen 210.

[0083] Alternatively, see Figure 4 Filter assembly 200 further includes an absorber 260 disposed at second end 212 of filter screen 210 and configured to absorb oil and other contaminants dripping from filter screen 210. Absorbing contaminants such as oil and other contaminants flowing from filter screen 210 by absorber 260 facilitates collection and disposal of the contaminants, reduces the frequency of recycling and disposal of the contaminants, and facilitates maintenance of filter screen 210.

[0084] Furthermore, the absorption portion 260 may be disposed in the groove 246 to ensure that the absorption portion 260 reliably absorbs dirt such as oil that flows down from the filter 210 .

[0085] Of course, the absorption portion 260 may also be disposed at the second end 212 of the support member 230 close to the filter 210 , or the absorption portion 260 may also be disposed at the second end 212 of the filter 210 ; this is not specifically limited here.

[0086] It should be noted that when the absorption part 260 is provided on the support member 230 or the filter 210 , the absorption part 260 can be connected to the support member 230 or the filter 210 by bonding or snapping, so as to improve the reliability of the absorption part 260 .

[0087] It should also be noted that when the absorption portion 260 is saturated with the absorption of stains such as oil, the absorption portion 260 can be replaced separately to reduce the maintenance cost of the filter assembly 200.

[0088] Figure 5 This is a schematic diagram of the structure of the filter assembly 200 in another embodiment of the present invention; it should be understood that please refer to Figure 5 In some embodiments, the filter assembly 200 may not be provided with the absorption portion 260 .

[0089] In a preferred embodiment, the absorption part 260 has flame retardancy and oil solidification properties; the absorption part 260 has flame retardancy and is not easily ignited even in a high temperature environment, thereby ensuring safety; the absorption part 260 has oil solidification properties and can prevent oil from dripping from the absorption part 260, thereby ensuring a good oil absorption effect of the absorption part 260.

[0090] Of course, in some embodiments, the absorbent portion 260 may have only one of the flame retardancy and the oil solidification properties.

[0091] The material for preparing the absorption part 260 can be set as needed. For example, a non-woven fabric made of polypropylene (PP) material with lipophilicity and high oil retention capacity can be used, and no specific limitation is made here.

[0092] It should be noted that, in order to make the absorption portion 260 have oil solidification properties, an oil solidifying agent such as paraffin may be added to the absorption portion 260 .

[0093] The air conditioner 010 of this embodiment can be used in places where the air contains oil mist, such as kitchens, and when in use, the filter 210 located at the air inlet 101 can be used to filter the oil in the air.

[0094] In summary, the filter assembly 200 of the present invention and the filter 210 in the air conditioner 010 are tilted, which can allow the oil and other stains collected on the filter 210 to flow down the filter 210, thereby improving the accumulation of stains on the filter 210, that is, reducing the oil and other stains remaining on the filter 210, thereby improving the problem of increased pressure loss after the filter 210 collects oil mist and other stains, and improving the problem of decreased air volume caused by pressure loss.

[0095] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
