Fig. 4 is a schematic perspective view showing a filter screen assembly 10 for an air conditioning apparatus 1 in which a plurality of (for example, two) filter screens 100 shown in fig. 1 are arranged side by side in a first direction (longitudinal direction) as a sliding direction according to an embodiment of the present invention, fig. 5 is a schematic view showing the filter screen assembly 10 shown in fig. 4 as viewed from an outside direction, fig. 6 to 8 are partial schematic views, as viewed in a direction B-B in fig. 5, showing that the sliding portions 111 and 112 of two adjacent filter screens 100 slide with each other and the relative positions of the two adjacent filter screens 100 change in the filter screen assembly 10 shown in fig. 3, in which fig. 6 is a view showing a first relative position (minimum distance) when two adjacent filter screens 100 are closest to each other, fig. 7 is a view showing a second relative position (maximum distance) when two adjacent filter screens 100 are farthest from each other, and fig. 8 is a view showing that two adjacent filter screens 100 are in the first relative position (minimum distance) shown in fig. 6 and the second relative position (maximum distance) shown in fig. 7.
As shown in fig. 1 and 2, a filter screen 100 according to an embodiment of the present invention includes: a filter frame 110 as a main frame of the filter, wherein the filter frame 110 is frame-shaped, and has two opposite first side ends (left and right side ends) in a first direction (left and right direction) and two opposite second side ends (upper and lower side ends) in a second direction (up and down direction) on a plane where the filter frame 110 is located, the first side ends and the second side ends are perpendicular to each other, and an opening is formed in a middle portion of the plane where the filter frame 110 is located so that air can flow through the middle portion; and a filter member 120 attached to the filter frame body 110, covering an intermediate portion of the filter frame body 110, and filtering air flowing through the intermediate portion.
The term "perpendicular" as used herein includes, in addition to 90 ° in a strict geometric sense, a case where the first side end and the second side end are not exactly 90 ° but slightly smaller than 90 ° or slightly larger than 90 ° due to an error in manufacturing.
As shown in fig. 2, the first opposite side ends of the filter screen frame 110 in the first direction (left-right direction) are respectively formed with a sliding portion protruding outward in the first direction (or "protruding outward in a direction away from the filter material 120"). That is, a first sliding portion 111 that protrudes outward in a direction (left side) away from the filter member 120 from one end is formed at one first side end (e.g., left side end) of the filter frame body 110, a second sliding portion 112 that protrudes outward in a direction (right side) away from the filter member 120 from the other first side end (e.g., right side end) of the filter frame body 110 is formed, and the first sliding portion 111 and the second sliding portion 112, which are the sliding portions, are integrally molded with the filter frame body 110 by injection molding or mold release.
As shown in fig. 3, in the filter screen assembly 10 in which a plurality of (for example, two) filter screens 100 are arranged side by side in the first direction (left-right direction), the sliding portions of the two adjacent filter screens 100 can slide in the first direction with respect to each other or with respect to the air port frame 2 by the sliding surface.
In order to prevent the air from passing through the second direction (vertical direction) between the sliding portions of two adjacent filter screens 100 in the filter screen assembly 10, the sliding portions of the filter screens 100 constituting the filter screen assembly 10 extend in the second direction (see fig. 1 and 2), so that both ends (upper end and lower end) of the sliding portions in the second direction are flush with both ends (upper end and lower end) of the filter screen frame 110 of each filter screen 100 in the second direction, respectively, or at least one end of the sliding portions exceeds one end (upper end or lower end) of the filter screen frame 110 in the second direction. That is, in the filter screen 100, both end portions of the slide portion in the second direction are each at least flush with second opposite side ends (upper side end and lower side end) of the filter screen frame body 110 in the second direction. Therefore, the structure is simple, the universality is good, the management of parts can be simplified, and the air tightness between the adjacent filter screens can be ensured.
In view of flatness of the filter unit 10 and ease of processing of the filter 100, it is more preferable that the filter 100 has the first sliding portion 111 and the second sliding portion 112 having the same dimension in the second direction as the filter frame 110, as shown in fig. 2.
In the filter screen 100, as shown in fig. 3, the first sliding portion 111 and the second sliding portion 112 are located at different positions in a third direction perpendicular to the plane of the filter screen frame 110, in other words, the sliding surface of the first sliding portion 111 and the sliding surface of the second sliding portion 112 are respectively directed to different side surfaces (an inner surface 111a and an outer surface 112 a) in the direction perpendicular to the plane of the filter screen frame 110. Further, a slip surface of the first slip portion 111 facing the second slip portion 112 in the third direction (an inside surface 111a of the first slip portion 111 located at the left end in fig. 3) and a slip surface of the second slip portion 112 facing the first slip portion 111 in the third direction (an outside surface 112a of the second slip portion 112 located at the right end in fig. 3) are on the same horizontal plane. Thus, a plurality of filters 100 of the same system can be used to adapt to a plurality of air conditioners 1 having different sizes of the air outlet frame 2.
In the filter unit 10 in which a plurality of (for example, two) filters 100 are arranged side by side in the first direction, assuming that the dimension of the first slide portion 111 projecting outward, that is, the dimension projecting leftward from one (left side end) of the first opposite side ends of the filter frame body 110 is L1, and the dimension of the second slide portion 112 projecting outward, that is, the dimension projecting rightward from the other (right side end) of the first opposite side ends of the filter frame body 110 is L2, by bringing the outer side surface 112a of the second slide portion 112 positioned at the right end of the left filter 100 in fig. 4 and 5 and the inner side surface 111a of the first slide portion 111 positioned at the left end of the right filter 100 in fig. 4 and 5 into contact with each other in the first direction and sliding relative to each other, the minimum separation distance (dimension of non-sliding, the distance between the adjacent side ends of the two adjacent filter frame bodies 110 in the first direction is the larger of L1 and L2) and the range (including the minimum distance and not including the maximum distance) of the maximum distance (the critical distance at which the maximum slip occurs and the two adjacent filter frame bodies 110 start to disengage, and the distance between the adjacent side ends of the two adjacent filter frame bodies 110 in the first direction is the sum of L1 and L2) shown in fig. 5, the relative position between the respective filter screens 100 constituting the filter screen assembly 10 is adjusted, for example, to a certain relative position shown in fig. 6, to reliably cover the entire air outlet frame 2 of the plurality of air-conditioning apparatuses 1 having different sizes of the air outlet frames 2 (in this embodiment, the sizes of the air outlet frames 2 in the first direction are different). At the same time, when the relative positions of the plurality of filter screens 100 in the filter screen assembly 10 are changed, air can be prevented from passing between the inside surface 111a of the first slide portion 111 and the outside surface 112a of the second slide portion 112 of the adjacent filter screens 100, and the airtightness between the adjacent filter screens 10 (the entire filter screen assembly 10) can be reliably ensured. Further, it is preferable that the dimension L1 of the first sliding portion 111 in the first direction is equal to the dimension L2 of the second sliding portion 112 in the first direction, so that adjacent filter screens 1 can be slid by a larger distance at the same minimum separation distance.
According to the structure of the filter screen 100 and the filter screen assembly 10 according to an embodiment of the present invention, the ventilation paths other than the ventilation path through which the air passes through the respective filter materials 120 of the plurality of filter screens 100 in the filter screen assembly 10 can be completely closed, and thus, the air (return air) that has not passed through the filter materials 120 of the filter screen assembly 10 (filter screen 100) can be prevented from entering the inside of the air conditioning apparatus 1.
Furthermore, according to the utility model discloses an embodiment's filter screen 100, because simple structure, the commonality is good, can utilize the filter screen 100 of a plurality of same standard to constitute filter screen assembly 10 with adjustable first direction to adapt to the multiple air conditioning equipment 1 that wind gap frame size (the first direction size of wind gap frame 2) is different, and simplify the management of spare part.
In addition, according to the structure of the filter screen 100 and the filter screen assembly 10 of an embodiment of the present invention, the sliding portions of the two adjacent filter screens 100 can slide relative to each other or relative to the air vent frame 2 through the sliding surfaces in the first direction, and the positions of the first sliding portion 111 and the second sliding portion 112 in the third direction are different, and the sliding surfaces of the first sliding portion 111 and the second sliding portion 112 facing each other in the third direction are at the same horizontal plane, so that the sealing performance between the two adjacent filter screens 100 can be reliably ensured. Meanwhile, two adjacent filter screens 100 abutting against each other and sliding, and thus the filter screen assemblies 10 can always be kept flush, and therefore, the situation that one filter screen 100 in the filter screen assembly 10 is tilted relative to the other filter screens 100 does not occur.
Next, a filter screen 100 according to an embodiment and a modification of the present invention will be described with reference to fig. 9 and 10. Fig. 9 and 10 are partial schematic views respectively showing views in the direction B-B in fig. 5 when two adjacent filter screens 100 are arranged side by side in the first direction (left-right direction) in the embodiment and the modification of the present invention.
In the embodiment of the present invention, as shown in fig. 3, the sliding portion (the first sliding portion 111 and the second sliding portion 112) has a sliding portion main body in which one end is connected to the end of the filter screen frame body 110 and the other end protrudes outward in a strip shape in the first direction (the left-right direction), but in the embodiment and the modification of the present invention, as shown in fig. 9 and 10, the sliding portion (the first sliding portion 111 and the second sliding portion 112) has: a sliding part main body having one end connected to an end of the filter screen frame 110; and bent portions 113 and 114 formed by bending the other end of the slide portion main body of the slide portion (the first slide portion 111 and the second slide portion 112) in the third direction (a direction perpendicular to the plane of the filter frame body 110).
In the embodiment and the modification shown in fig. 9 and 10, both the first sliding portion 111 and the second sliding portion 112 have the sliding portion main body and the bent portions 113 and 114, but the present invention is not limited to this, and only the first sliding portion 111 may have the sliding portion main body and the bent portion 113, or only the second sliding portion 112 may have the sliding portion main body and the bent portion 114. In the case where only the first sliding portion 111 or only the second sliding portion 112 has the bent portion 113 or the bent portion 114, the bending direction of one bent portion 113 or 114 of the first sliding portion 111 and the second sliding portion 112 having the bent portion 113 or 114 may be the inside surface 111a or the outside surface 112a facing the other sliding portion main body of the first sliding portion 111 and the second sliding portion 112 not having the bent portion in the third direction, or may be opposite to the inside surface 111a or the outside surface 112a of the other sliding portion main body of the first sliding portion 111 and the second sliding portion 112 not having the bent portion in the third direction.
In the case where both the first sliding portion 111 and the second sliding portion 112 have the bent portions 113 and 114, it is preferable that the bending direction of the bent portion 113 is opposite to the bending direction of the bent portion 114, and in this case, the bent portions 113 and 114 may be bent back to back as in the embodiment of fig. 9, or may be bent to face each other as in the modification of fig. 10.
In the embodiment (the embodiment and the modification) of the present invention, the position in the third direction of the first sliding portion 111 is located further to the outside of the machine than the position in the third direction of the second sliding portion 112, and therefore, when the bent portions 113 and 114 are bent back to each other, as shown in fig. 9, the bent portion 113 is bent to the outside of the machine from the other end of the sliding portion main body of the first sliding portion 111, the bent portion 114 is bent inward from the other end of the sliding portion main body of the second sliding portion 112, and when the bent portions 113 and 114 are bent toward each other, as shown in fig. 10, the bent portion 113 is bent inward from the other end of the sliding portion main body of the first sliding portion 111, and the bent portion 114 is bent outward from the other end of the sliding portion main body of the second sliding portion 112.
When the bent portions 113 and 114 are bent back to each other, as shown in fig. 9, a sliding surface on which the first sliding portion 111 slides with respect to the second sliding portion 112 is an inside surface 111a of the sliding portion main body of the first sliding portion 111 (a surface below the first sliding portion 111 in fig. 9), and a sliding surface on which the second sliding portion 112 slides with respect to the first sliding portion 111 is an outside surface 112a of the sliding portion main body of the second sliding portion 112 (a surface above the first sliding portion 111 in fig. 9). At this time, the inside surface 111a of the slide body of the first slide 111 and the outside surface 112a of the slide body of the second slide 112 are on the same horizontal plane. In addition, the same is true when the bending direction of one of the bent portions 113 or 114 having the bent portion 113 or 114 of the first sliding portion 111 and the second sliding portion 112 is opposite to the other of the inside surface 111a or the outside surface 112a having no bent portion of the first sliding portion 111 and the second sliding portion 112 in the third direction. Further, in the case where the bending direction of one bending portion 113 or 114 of the first sliding portion 111 and the second sliding portion 112 having one bending portion 113 or 114 faces the inside surface 111a or the outside surface 112a of the other sliding portion main body of the first sliding portion 111 and the second sliding portion 112 not having the bending portion in the third direction, it is preferable that the dimension of one sliding portion main body of the first sliding portion 111 and the second sliding portion 112 having the bending portion 113 or 114 is equal to or larger than the dimension of the other sliding portion main body of the first sliding portion 111 and the second sliding portion 112 not having the bending portion 113 or 114 in the horizontal direction, so that the sliding surfaces are the inside surface 111a of the sliding portion main body of the first sliding portion 111 and the outside surface 112a of the sliding portion main body of the second sliding portion 112, and at this time, the inside surface 111a of the sliding portion main body of the first sliding portion 111 and the outside surface 112a of the sliding portion main body of the second sliding portion 112 are on the same horizontal plane.
In addition, when the bent portions 113 and 114 are bent so as to face each other, as shown in fig. 10, the sliding surfaces on which the first sliding portion 111 slides with respect to the second sliding portion 112 are the inside surface 111a (the surface below the first sliding portion 111 in fig. 10) of the first sliding portion 111 and the inside surface 113a (the surface below the bent portion 113 in fig. 10) of the bent portion 113 of the first sliding portion 111, and the sliding surfaces on which the second sliding portion 112 slides with respect to the first sliding portion 111 are the outside surface 112a (the surface above the second sliding portion 112 in fig. 10) of the second sliding portion 112 and the outside surface 114a (the surface above the bent portion 114 in fig. 10) of the bent portion 114 of the second sliding portion 112. At this time, the inboard surface 111a of the first slide moving portion 111 and the outboard surface 114a of the bent portion 114 of the second slide moving portion 112 are at the same level, and the outboard surface 112a of the second slide moving portion 112 and the inboard surface 113a of the bent portion 113 of the first slide moving portion 111 are at the same level.
However, the present invention is not limited to this, and the sliding surface on which the first sliding portion 111 slides with respect to the second sliding portion 112 may be the inside surface 111a of the sliding portion main body of the first sliding portion 111, and the sliding surface on which the second sliding portion 112 slides with respect to the first sliding portion 111 may be the outside surface 114a of the bending portion 114 of the second sliding portion 112, and at this time, the inside surface 111a of the sliding portion main body of the first sliding portion 111 and the outside surface 114a of the bending portion 114 of the second sliding portion 112 are at the same level, and the outside surface 112a of the sliding portion main body of the second sliding portion 112 and the inside surface 113a of the bending portion 113 of the first sliding portion 111 are not at the same level (and do not contact).
Further, a slip surface on which the first slip portion 111 slips with respect to the second slip portion 112 may be an inside surface 113a of the bent portion 113 of the first slip portion 111, and a slip surface on which the second slip portion 112 slips with respect to the first slip portion 111 may be an outside surface 112a of a slip portion main body of the second slip portion 112. At this time, the outboard surface 112a of the slide body of the second slide part 112 and the inboard surface 113a of the bent part 113 of the first slide part 111 are at the same level, and the inboard surface 111a of the slide body of the first slide part 111 and the outboard surface 114a of the bent part 114 of the second slide part 112 are not at the same level (are not in contact).
In addition, in the case where the bending portions 113 and 114 are bent to face each other, it is preferable that, as shown in fig. 10, the sizes of the sliding surfaces (the inside surface 111a of the first sliding portion 111, the inside surface 113a of the bending portion 113 of the first sliding portion 111, the outside surface 112a of the second sliding portion 112, and the outside surface 114a of the bending portion 114 of the second sliding portion 112) are smaller than the size of the sliding portion main body of the sliding portions (the first sliding portion 111 and the second sliding portion 112) in the horizontal direction, whereby even in the case where the bending portions 113 and 114 are present, the inside surface 113a of the sliding portion main body of the bending portion 113 and/or the outside surface 114a of the bending portion 114, and the outside surface 112a of the sliding portion main body of the second sliding portion 112 which also serves as sliding surfaces, can be used to freely slide relative to each other in the first direction, and the relative positions of the filter screens 100 constituting the filter screen assembly 10 can be adjusted within the sliding range.
Thus, in the embodiment of the present invention, by adopting the structure shown in fig. 9, in addition to the same technical effects as those of the embodiment, it is possible to ensure that the sliding portions (the first sliding portion 111 and the second sliding portion 112) have a uniform wall thickness after the injection molding and the demolding process, and to achieve the technical effects of making the sliding of the adjacent filter screens 100 relative to each other in the first direction smoother and smoother. In addition, in the modification of the present invention, the structure shown in fig. 10 has substantially the same technical effects as the structure shown in fig. 9, and the slippage sections 113 and 114 facing each other prevent the adjacent filter screens 100 from being separated from each other.
Next, referring to fig. 11 to 16, a further configuration of the filter screen assembly 10 and attachment of the filter screen assembly 10 to the air-conditioning apparatus 1 will be described in detail, taking the first direction (left-right direction) and the second direction (up-down direction) of the filter screen assembly 10 shown in fig. 4 and 5 as examples. However, it should be understood by those skilled in the art that the filter screen assembly 10 shown in fig. 4 and 5 may be replaced with one another in the left-right direction and the up-down direction, and in this case, the positions of the engaging portion 115, the flange portion 116 (the stepped groove 6), the stopper structure 117, and the like, which are slid with respect to the outlet frame 2 of the air conditioner 1, are changed accordingly.
Fig. 11 is a schematic view showing the air conditioner 1 according to the present invention, in which the filter screen assembly 10 shown in fig. 4 and 5, in which a plurality of filter screens 100 are arranged side by side in a first direction (longitudinal direction), is installed and disposed at the tuyere frame 2 of the generally rectangular shaped tuyere of the air conditioner 1. Fig. 12 is a schematic side view showing the filter screen assembly 10 shown in fig. 3, viewed in the direction C-C in fig. 5. Fig. 13 to 15 are enlarged schematic views of a portion D of fig. 11 showing an installation position of the filter screen assembly 10 to the tuyere frame 2 (fig. 13 is the tuyere sheet metal part 3+ the fan ceiling 4, fig. 14 is only the tuyere sheet metal part 3, and fig. 15 is the tuyere sheet metal part 3+ the sound insulation material 5) in different situations, wherein a fixture structure S such as a house beam keel in fig. 11 is not shown. Fig. 16 is an enlarged perspective view showing a stopper portion for stopping the filter screen assembly 10 when the filter screen assembly 10 is attached to the air port frame 2, and shows a stopper structure 117 formed in the filter screen assembly 10 (the filter screen frame 110 of each filter screen 100).
As shown in fig. 11, a filter screen assembly 10, which is formed by arranging a plurality of filter screens 100 shown in fig. 2, 7 or 8 side by side in a first direction (length direction) as shown in fig. 4 and 5, is provided at the tuyere frame 2 of the generally rectangular tuyere of the air conditioner 1 of the present invention. In the filter screen assembly 10 shown in fig. 4 and 5, a first direction in which the filter screens 100 slide relative to each other corresponds to a length direction of the air port frame 2, and a second direction of the filter screen assembly 10 corresponds to a width direction of the air port frame 2. In this case, the filter screen assembly 10 is fixed to the air inlet frame 2 at the air inlet of the air conditioner 1 by the engaging portion 115 shown in fig. 13 to 15, and is mounted on the fixture structure S (see fig. 11) such as a house beam keel by the stepped groove 6 shown in fig. 13 to 15, and the filter screen assembly 10 is limited in the sliding movement of the filter screen assembly 10 in the first direction (left-right direction) with respect to the air inlet frame 2 by the limiting structure 117 shown in fig. 16, so that the filter screens 100 in the filter screen assembly 10 are prevented from excessively sliding in the first direction, and the entire filter screen assembly 10 is prevented from falling off the air inlet frame 2.
(engaging part 115)
At least one engaging portion 115 is formed at second opposite side ends (an upper side end 11U and a lower side end 11L in fig. 5) of the filter screen assembly 10 shown in fig. 4 and 5, respectively, and the engaging portion 115 has an engaging portion 115a that is inclined with respect to a plane in which the filter screen frame body 110 is located in a direction away from the filter material 120 (for example, inclined with respect to the plane in which the filter screen frame body 110 is located toward an inside of the machine and outward in a second direction (vertical direction)). That is, at one second side end (upper side end 11U) of the filter screen assembly 10, as shown in fig. 12, an engaging portion 115 having an engaging portion 115a inclined toward the machine inner side and toward the upper side (inclined toward the upper left in fig. 12) with respect to the plane in which the filter screen frame 110 is located, for example, is formed, and at the other second side end (lower side end 11L) of the filter screen assembly 10, an engaging portion 115 having an engaging portion 115a inclined toward the machine inner side and toward the lower side (inclined toward the lower left in fig. 12) with respect to the plane in which the filter screen frame 110 is located, for example, is formed. The clamping portion 115a clamps the air inlet frame 2 at the air inlet of the air conditioner 1 when the filter screen assembly 100 is mounted to the air inlet frame 2. The engaging portion 115 including the engaging portion 115a is formed integrally with the filter unit 10 (more specifically, the filter frame 110 of the filter 100 constituting the filter unit 10) by, for example, injection molding or mold release.
In addition, the tuyere frame 2 may have different configurations in different cases, for example, fig. 13 shows a case of being configured by the tuyere metal plate 3+ the fan ceiling 4, fig. 14 shows a case of being configured by only the tuyere metal plate 3, and fig. 15 shows a case of being configured by the tuyere metal plate 3+ the soundproof material 5. The tuyere frame 2 of different cases has different thicknesses. The smaller the inclination angle of the engaging portion 115a of the engaging portion 115 with respect to the plane of the filter screen housing 110, the less the filter screen assembly 10 is likely to fall off from the air port frame 2 at the air port in the direction out of the machine when the engaging portion 115a is engaged, but the smaller the thickness that can be accommodated (the larger the thickness of the air port frame 2 cannot be engaged between the engaging portion 115a of the engaging portion 115 and the machine-side end surface 116a as a clamping surface of the flange portion 116 described later), the less the versatility of the air port frame 2 in various cases (various thicknesses) is. On the contrary, the larger the inclination angle of the engaging portion 115a of the engaging portion 115 with respect to the plane of the filter screen frame 110 is, the larger the thickness can be, so that the smaller thickness of the tuyere frame 2 composed only of the tuyere metal plate 3 shown in fig. 12 or the larger thickness of the tuyere frame 2 composed of the tuyere metal plate 3 and the sound insulating material 5 shown in fig. 13 can be applied, and the versatility is strong, but accordingly the filter screen assembly 10 is more likely to fall from the tuyere frame 2 at the tuyere portion in the machine-exterior direction. Therefore, in view of the mounting stability and the versatility of the tuyere frame 2 for different situations (different thicknesses), the inclination angle is preferably set to 10 ° to 50 °, more preferably to about 30 °, in order to more evenly balance the advantages of both.
As shown in fig. 11 to 13, the engaging portion 115a of the engaging portion 115 is engaged with the tuyere frame 2 (the tuyere metal sheet 3+ the fan top plate 4, only the tuyere metal sheet 3, or the tuyere metal sheet 3+ the sound insulating material 5). For example, the engaging portion 115a may engage with an edge portion of the tuyere frame 2, or an engaged portion (for example, an engaging groove) into which the engaging portion 115a of the engaging portion 115 enters may be formed in the tuyere frame 2, and in this case, a size of the engaged portion in the first direction must be larger than a size of the engaging portion 115a of the engaging portion 115 in the first direction, otherwise the engaging portion 115 cannot smoothly enter and engage with the engaged portion of the tuyere frame 2 without being interfered by a main body of the tuyere frame 2. However, if the dimension of the engaged portion in the first direction is too large compared to the dimension of the engaging portion 115 in the first direction, when the filter screen assembly 10 is slid on the tuyere frame 2 in the first direction (left-right direction), the adjacent filter screens 100 may be excessively slid to be disengaged, and therefore, it is preferable that the width dimension of the engaged portion formed in the tuyere frame 2 is larger than the width dimension of the engaging portion 115a of the engaging portion 115 and does not exceed the smaller of L1 and L2, whereby it is possible to prevent the relative sliding movement of any adjacent two filter screens 100 among the plurality of filter screens 100 from reaching or exceeding the maximum distance after the filter screen assembly 10 is mounted on the tuyere frame 2.

Further, at the second opposite side ends (the upper side end 11U and the lower side end 11L in fig. 5) of the filter screen assembly 10 shown in fig. 4 and 5, as shown in fig. 12, at least one flange portion 116 is formed, respectively, the flange portion 116 protruding outward in the second direction from the second opposite side ends (i.e., protruding upward from the upper side end 11U in the second opposite side ends and protruding downward from the lower side end 11L in the second opposite side ends in fig. 5), and the flange portion 116 is provided to extend continuously in the first direction or to extend on both sides of the engaging portion 115 in the first direction. An end surface (i.e., an inside end surface 116 a) of the flange portion 116 facing the inside (i.e., the inside of the air conditioner 1) serves as a clamping surface, and clamps the air port frame 2 together with the engaging portion 115a of the engaging portion 115.
Accordingly, when the filter screen frame body 10 is mounted to the air outlet frame 2, the inclined engaging portion 115a of the engaging portion 115 engages with the air outlet frame 2, and at the same time, the inner end surface 116a of the flange portion 116 serves as a holding surface for holding and blocking the air outlet frame 2 together with the engaging portion 115a of the engaging portion 115, so that the inclined engaging portion 115a of the engaging portion 115 can prevent the filter screen assembly 10 from dropping from the air outlet frame 2 in the direction toward the outside of the air conditioner, and the inner end surface 116a of the flange portion 116 can engage with the engaging portion 115a of the engaging portion 115 and the air outlet frame 2 together, thereby preventing the filter screen assembly 10 from moving in the direction toward the inside of the air conditioner 1 when air is sucked.
(notch cuttype groove 6)
An end face of the flange portion 116 remote from the air-conditioning apparatus 1 (i.e., an outside end face 116 b) and second side ends (an upper side end 11U and a lower side end 11L in fig. 5) of the filter screen assembly 10 constitute a stepped groove 6 recessed toward one side (an inside) of the air-conditioning apparatus 1. That is, one (upper side end 11U) of the outside end face 116b of the flange portion 116 of one (e.g., upper side in fig. 4, 5) of the second directions and the second opposite side end of the screen assembly 10 constitutes a stepped groove 6 recessed toward the inside and the lower side (left and lower sides in fig. 12), and the other (lower side end 11L) of the outside end face 116b of the flange portion 116 of the other (e.g., lower side in fig. 4, 5) of the second directions and the second opposite side end of the screen assembly 10 is formed with a stepped groove 6 recessed toward the inside and the upper side (left and upper sides in fig. 12). The stepped groove 6 formed by the outboard end surface 116b of the flange portion 116 and the second opposite side end of the screen unit 10 is used to mount the air conditioner 1 on a fixture structure S (e.g., a house beam runner) of a building, so that the screen unit 10 can be positioned, and the air conditioner 1 can be supported by the fixture structure S of the building to share and reduce the force applied to other fastening structures when the air conditioner 1 is fastened by the other fastening structures, so that the air conditioner 1 can be fastened more firmly in the ceiling.
(Limit structure 117)
In addition, a stopper structure 117 is formed at a second side end (an upper side end 11U and/or a lower side end 11L in fig. 3) of at least one side of the filter screen assembly 10 shown in fig. 4 and 5 toward the air conditioner 1 (i.e., the inside of the air conditioner), and the stopper structure 117 is formed in pairs on the first side ends of two outermost ends of the filter screen assembly 10 opposite to each other in the first direction to restrict the sliding movement of the filter screen assembly 10 with respect to the air outlet frame 2 when the filter screen assembly 10 is mounted to the air outlet frame 2. The stopper 117 is U-shaped as shown in fig. 16, for example, and includes: the outer limiting portion 117a close to the outermost end of the first side end is used for preventing the filter screen 100 of the filter screen assembly 10 located at the outermost end in the first direction from excessively sliding towards the middle, so that the two ends in the first direction of the air inlet frame 2 are not effectively shielded by the filter screen assembly 10 and air leakage is avoided; an inner side limiting portion 117b of the first side end far from the outermost end, for preventing the filter screen 100 of the filter screen assembly 10 located at the outermost end in the first direction from being excessively slid toward the outer end, so as to reduce an ineffective shielding area; and an avoiding portion 117c between the outer side limiting portion and the inner side limiting portion, which can be used for avoiding the tuyere sheet metal part 3 of the tuyere frame 2, thereby enabling the sliding of the filter screen 100 of the filter screen assembly 10 to be smoother.
In addition, taking the filter screen assembly 10 shown in fig. 4 and 5 as an example, the pair of limiting structures 117 formed at the two outermost ends opposite to each other in the first direction of the filter screen assembly 10 may be formed at the upper side end 11U of the filter screen assembly 10 and at the upper left corner and the upper right corner of the filter screen assembly 10, may be formed at the lower side end 11L of the filter screen assembly 10 and at the lower left corner and the lower right corner of the filter screen assembly 10, or may be formed at the upper side end 11U and the lower side end 11L of the filter screen assembly 10 and at the upper left corner and the lower right corner of the filter screen assembly 10, or at the lower left corner and the upper right corner. It is further preferable that the limiting structures 117 are respectively formed at the upper side end 11U and the lower side end 11L of the filter screen assembly 10 and at the upper left corner, the upper right corner, the lower left corner and the lower right corner of the filter screen assembly 10, and therefore, compared with a case where the sliding of the filter screen assembly 10 with respect to the air inlet frame 2 is limited by a pair of limiting structures 117, the limiting structure can more reliably limit the sliding position and prevent the dislocation and the air leakage caused by the fact that the filter screen assembly 10 cannot be installed in place in the second direction by two pairs of limiting structures 117.
However, in the case of having the one pair of limit structures 117 or the two pairs of limit structures 117 as described above, since the limit structures 117 of the left filter screen 100 and the right filter screen 100 constituting the filter screen assembly 10 shown in fig. 4 and 5 are different in position from the limit structures 117, the filter screens 100 of two specifications still need to be assembled, so that management of component parts becomes complicated, and there is a possibility that the filter screens of different specifications may be mistakenly taken at the time of field installation, so that the installation efficiency is significantly deteriorated, and therefore, it is more preferable that the limit structures 117 are formed at the upper left corner and the upper right corner, or the lower left corner and the lower right corner of the filter screen 100 constituting the filter screen assembly 10, respectively. Most preferably, the limit structures 117 are formed at the upper left corner, the upper right corner, the lower left corner and the lower right corner of the filter screen 100 constituting the filter screen assembly 10, respectively. From this, can further have the commonality and can utilize the filter screen of a plurality of same standard to come the adaptation to the effect of multiple air conditioning equipment of wind gap frame size difference on the basis of the effect of preceding structure.
In the air conditioner 1 of the present invention having the filter screen assembly 10 installed thereon, the filter screen assembly 10 is conveniently replaced by engaging at least one engaging portion 115 formed on the end surface of the second direction both ends of the filter screen assembly 10 with the tuyere frame 2 so as to engage the engaging portion 115a, for example, to install the filter screen assembly 10 with respect to the tuyere frame 2 at the tuyere of the air conditioner 1. At this time, since the engaging portion 115a of the engaging portion is inclined toward the inside of the air conditioner and toward the outside in the second direction with respect to the plane (the plane perpendicular to the third direction) of the filter screen frame 110, a portion (particularly, the filter material 120) of the filter screen assembly 10 other than the engaging portion 115a is exposed on the outside of the air outlet frame 2, and the inclined engaging portion 115a can correspond to the air outlet frames 2 in different situations (different thicknesses), and thus can correspond to various different scenes of the air conditioner indoor unit.
Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the temperature of the molten metal is controlled,
the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described herein. Accordingly, modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.

That is, at this time, opposite side ends (both ends in the first direction) of the filter frame body 110 provided in the sliding portion are left and right ends, and the filter unit 10 is formed by arranging a plurality of filters 100 side by side in the left and right direction so as to divide the tuyere frame 2 of the tuyere portion left and right. However, opposite side ends (both ends in the first direction) of the filter frame body 110 provided in the sliding portion may be upper and lower ends, and the filter unit 10 may be formed by arranging a plurality of filters 100 in parallel in the upper and lower directions so as to vertically divide the tuyere frame 2 of the tuyere portion.
(2) In the above-described configuration, the example has been described in which the position of the first sliding portion 111 in the third direction is located further to the outside than the position of the second sliding portion 112 in the third direction, but the present invention is not limited to this, and the position of the first sliding portion 111 in the third direction may be located further to the inside than the position of the second sliding portion 112 in the third direction. In addition, in the above-described structure, it is described that one first side end of the filter screen frame body 110 is a left side end, and the other side end of the filter screen frame body 110 is a right side end, but the present invention is not limited thereto, and one first side end may be a right side end, and the other side end of the filter screen frame body 110 is a left side end.
(3) In the above-described configuration, as shown in fig. 1 and 2, the small-sized filter screen 100 is exemplified, and in this case, one engaging portion 115 is formed at the center portion of the filter screen frame 110 of each filter screen 100 constituting the filter screen assembly 10 at the upper end 11U and the lower end 11L of the filter screen assembly 10 shown in fig. 4 and 5. However, the present invention is not limited to this, and a large-sized filter screen 100A may be used as shown in fig. 17, and in this case, the engaging portions 115A may be formed at a plurality of positions (for example, 1/3 position and 2/3 position) in the first direction of the filter screen frame 110A of each filter screen 100A constituting the filter screen assembly 10 at the upper end 11U and the lower end 11L of the filter screen assembly 10. The filter unit 10, which is formed by arranging a plurality of (two in fig. 3) filters 100 and 100A in parallel in the first direction, has a plurality of engaging portions 115 and 115A at both ends in the second direction, respectively (two engaging portions 115 in fig. 4 and 5, respectively, and four engaging portions 115A if all of the small-sized filters 100 in fig. 4 and 5 are replaced with the large-sized filter 100A shown in fig. 17).
Further, as shown in fig. 18, the engaging portions may be formed at both ends (upper end and lower end) in the second direction of the slide portions (the first slide portion 111 and the second slide portion 112) extending in the second direction, and thus the filter unit 10 in which two filters are arranged side by side in the first direction may have only one engaging portion 115 at both ends in the second direction. At this time, the flange portion 116 extends continuously in the first direction over the second opposite side ends (the upper end 11U and the lower end 11L) of the filter frame body 110.
(4) In the above-described structure, as shown in fig. 16, the case where the limiting structure 117 has the outer limiting portion 117a near the outermost end of the first side end, the inner limiting portion 117b far from the outermost end of the first side end, and the escape portion 117c between the outer limiting portion 117a and the inner limiting portion 117b to limit and escape the tuyere sheet metal member 3 in two directions has been described as an example, the filter screen 100 having the limiting structure 117 can be applied to the case of the filter screen assembly 10 in which a plurality of, particularly, two filter screens 100 are arranged side by side, and at this time, the two filter screens 100 located at the outermost ends in the first direction can also slide in the first direction with respect to the tuyere sheet metal member 3 of the tuyere frame 2.
However, the utility model discloses a limit structure is not limited to the spacing limit structure of this kind of two directions, under the filter screen subassembly 10 that forms by at least three filter screen 100 sets up side by side, two filter screens 100 that are located the outermost end of first direction can not take place to slide in the first direction for the wind gap sheet metal component 3 of wind gap frame 2 by itself, only be located one or more filter screens 100 in the middle of the first direction and can take place to slide in the first direction, at this moment, limit structure 117 as long as have can prevent that the filter screen 100 that is located the outermost end of first direction of filter screen subassembly 10 is by the spacing portion that excessively slides to the outer end, then also can be other arbitrary structures outside the form shown in fig. 16, at this moment, dodge portion 117c also can omit.
In addition, the limiting structure 117 is not limited to be integrally formed with the filter screen frame body 110 of the filter screen 100, and may be a limiting structure separately installed on the filter screen 100, so that the same system of the filter screen 100 can be considered, the limiting structure 117 can be flexibly installed, and interference caused by the air inlet frame 2 during installation is reduced.
(5) For example, in the above-described configuration, the case where the plurality of small-sized filters 100 shown in fig. 1 and 2 of the same system or the plurality of large-sized filters 100A shown in fig. 17 of the same system are arranged side by side in the first direction to form the filter assembly 10 has been described as an example, but one or more small-sized filters 100 shown in fig. 1 and 2 of the same system and one or more large-sized filters 100A shown in fig. 17 of the same system may be arranged side by side in the first direction to form the filter assembly 10, whereby more air conditioners 1 having different sizes of the air outlet frames 2 can be accommodated by using filter assemblies 10 of fewer sizes of the same system.
(6) For example, in the above-described configuration, the case where the first direction (left-right direction) and the second direction (up-down direction) are perpendicular to each other on the plane where the filter screen frame is located has been described as an example, but the present invention is not limited to this, and the first direction (left-right direction) and the second direction (up-down direction) may not be perpendicular to each other on the plane where the filter screen frame is located, and in this case, may be matched with the shape of the air outlet frame at the air outlet of the air conditioner. That is, the tuyere frame 2 in the present invention is generally rectangular in shape, but may have a parallelogram structure other than a rectangle.
(7) Finally, in the present specification, "large size" and "small size" of the filter net refer to relative concepts that the sizes of the filter net in the first direction are different, and the filter net of the same system refers to a form having the sliding portions (the first sliding portion 111 and the second sliding portion 112) and the engaging portion 115, and the flange portion 116 (and the stepped groove 6 and the stopper structure 117) manufactured by the same manufacturing method.
