[0045] It should be noted that, in the embodiments of the present application, a plurality includes a number of two or more.

[0046] See also Figure 3 and Fig.12 An embodiment of the present application provides a maintenance plate assembly 1, which includes a filter screen 11 and a maintenance plate 12.

[0047] See also Figure 3 and Figure 4 The maintenance panel 12 includes a panel 121 and a limit frame 122. The limit frame 122 is arranged on one side of the panel 121 in the thickness direction. The limit frame 122 defines a ventilation duct 122a. A vent 121a is formed at a portion of the panel 121 corresponding to the ventilation duct 122a. The filter 11 is arranged in the ventilation duct 122a. Air enters the ventilation duct 122a through the vent 121a and flows through the filter 11. The filter 11 is used to filter air.

[0048] The vent 121a is formed at a position of the panel 121 corresponding to the ventilation duct 122a, which means that the projection of the vent 121a is located within the projection range of the ventilation duct 122a, taking a plane perpendicular to the thickness direction as a projection plane.

[0049] See also Figure 1 and Figure 2 The embodiment of the present application also provides an air conditioning device, which includes the maintenance panel assembly 1 and the duct machine 2 in any one of the embodiments of the present application.

[0050] See also Figures 1 to 4The duct unit 2 has an indoor air inlet 2a, the maintenance panel assembly 1 is provided with the duct unit 2, and the filter 11 is located between the vent 121a and the indoor air inlet 2a. The ventilation duct 122a connects the vent 121a and the indoor air inlet 2a, and the air enters the ventilation duct 122a through the vent 121a, and then enters the indoor air inlet 2a after being filtered by the filter 11 in the ventilation duct 122a.

[0051] The maintenance plate assembly 1 provided in the embodiment of the present application can, on the one hand, provide an air filtering function for the duct machine 2 to reduce the probability of dust entering the interior of the duct machine 2, thereby extending the service life of the duct machine 2. On the other hand, the maintenance plate 12 can provide an installation position for the filter 11, thereby avoiding changing the structure of the original duct machine 2 for installing the filter 11, thus saving R&D costs. The filter 11 is installed on the maintenance plate 12, which also facilitates the disassembly and / or replacement of the filter 11.

[0052] In the air conditioning equipment provided in the embodiment of the present application, the filter 11 is installed on the maintenance plate 12, and the filter 11 assembly structure does not need to be designed on the duct unit 2.

[0053] In some embodiments, the duct unit 2 is disposed on the ceiling, an indoor air inlet 2a is formed on the lower surface of the duct unit 2, and the maintenance panel assembly 1 is disposed below the duct unit 2. In this case, the thickness direction of the panel is consistent with the up-down direction. For ease of description, the embodiment of the present application is described by taking the duct unit 2 disposed on the ceiling as an example.

[0054] It should be noted that, unless otherwise specified, the thickness direction in the embodiments of the present application refers to the thickness direction of the panel 121 .

[0055] The type of the filter 11 is not limited. Exemplarily, the filter 11 includes but is not limited to at least one of a primary filter 11, a HEPA (High Efficiency Particulate Air Filter) and a HAF (High Air Flow) electrostatic filter 11.

[0056] The primary filter 11 can filter dust through the mesh. For example, the primary filter 11 is usually made of nylon mesh, non-woven fabric and / or metal mesh. The primary filter 11 can filter large particles such as hair and / or coarse dust.

[0057] In one embodiment, the air duct unit 2 includes a housing, a heat exchanger and a fan. The housing is formed with a receiving chamber, an indoor air inlet 2a and an indoor air outlet. The indoor air inlet 2a and the indoor air outlet are both connected to the receiving chamber, and the fan and the heat exchanger are both located in the receiving chamber. The fan drives the airflow from the indoor air inlet 2a into the receiving chamber, and after heat exchange in the heat exchanger, it is blown out from the indoor air outlet. The heat exchanger is used to exchange heat with the air, thereby adjusting the temperature and humidity. The fan is used to drive the air flow.

[0058] In one embodiment, the housing includes a bottom plate, a top plate and four side plates, the top plate is located above the bottom plate, the four side plates are arranged around the bottom plate, and the top plate, the bottom plate and the four side plates are together arranged to form a receiving cavity. The housing is generally in a hexahedral shape, such as a cube or a cuboid.

[0059] In one embodiment, please refer to Figures 3 to 9 The limiting frame 122 includes a seat body 1221 and a guide rail 1222, and the seat body 1221 is fixed on the panel 121. The guide rail 1222 is formed with a guide groove 1222a, and a portion of the filter screen 11 is located in the guide groove 1222a. The guide groove 1222a can limit the filter screen 11 from escaping from the ventilation duct 122a along the thickness direction.

[0060] The guide rail 1222 is movably connected to the seat body 1221 , and the guide rail 1222 can move along the thickness direction and be locked to any one of a plurality of locking positions spaced apart along the thickness direction.

[0061] In this embodiment, the guide rail 1222 can restrict the filter 11 within the ventilation duct 122a. The guide rail 1222 is locked to any one of a plurality of locking positions spaced apart along the thickness direction to adjust the dimension of the ventilation duct 122a along the thickness direction of the panel 121. With such a design, the dimension of the ventilation duct 122a along the thickness direction is adjusted by the guide rail 1222 to facilitate the adaptation of filter screens 11 of different thicknesses, thereby being compatible with filter screens 11 of various thicknesses, such as different filtration efficiencies.

[0062] In one embodiment, please refer to Figures 3 to 9 as well as Fig.11 The maintenance plate 12 includes a locking member 123, which connects the seat body 1221 and the guide rail 1222 to lock the guide rail 1222 to any one of a plurality of locking positions. The locking member 123 can lock the guide rail 1222 to the seat body 1221 to limit the movement of the guide rail 1222 in the thickness direction.

[0063] In one embodiment, please refer to Figures 3 to 11 The locking member 123 is rotatably connected to the seat body 1221, and the locking member 123 has a locked state and an unlocked state in the rotation direction. The guide rail 1222 is formed with a movable groove 1222b extending along the thickness direction, and at least a portion of the locking member 123 is inserted into the movable groove 1222b.

[0064] The locking member 123 rotates to the unlocked state, and the guide rail 1222 can move in the thickness direction to allow the locking member 123 to slide in the movable groove 1222b. The locking member 123 rotates to the locked state, and the locking member 123 can lock the guide rail 1222 to any locking position.

[0065] For example, when the filter 11 of a different size needs to be replaced, the locking member 123 is rotated to the unlocked state, the guide rail 1222 and the seat 1221 move relative to each other, the locking member 123 slides in the movable groove 1222b, and the guide rail 1222 can move to the target locking position along the thickness direction to adjust the size of the ventilation duct 122a along the thickness direction. When the filter 11 is replaced, the locking member 123 is rotated to the locked state, and the locking member 123 locks the guide rail 1222 to the target locking position.

[0066] In this embodiment, the locking member 123 rotates relative to the seat body 1221 to switch between the locked state and the unlocked state. At least a portion of the locking member 123 is inserted into the movable groove 1222b to achieve locking and relative movement between the locking member 123 and the guide rail 1222.

[0067] It is understandable that the number of locking positions is not limited, and exemplary, the locking positions can be two, three or even more. That is, the size of the filter screen 11 that can be accommodated in the ventilation duct 122a can be two, three or even more. Exemplarily, the size of the filter screen 11 includes but is not limited to 0.75 inches and above, and exemplary, the size of the filter screen 11 can be 0.75 inches or 1.5 inches, etc.

[0068] In one embodiment, please refer to Figures 3 to 11 The movable groove 1222b includes a sliding section 1222ba and a plurality of locking sections 1222bb. The plurality of locking sections 1222bb are spaced apart along the thickness direction. Two adjacent locking sections 1222bb are connected by the sliding section 1222ba. The size of the locking section 1222bb along the first direction is greater than the size of the sliding section 1222ba along the first direction.

[0069] The locking member 123 has a knob 1231, and the knob 1231 is rotated to change the direction of the long end 1231a of the knob 1231. The long end 1231a of the knob 1231 refers to the longest part of the knob 1231. The size of the long end 1231a of the knob 1231 is larger than the size of the sliding section 1222ba along the first direction, and smaller than the size of the locking section 1222bb along the first direction.

[0070] In the locked state, the long end 1231 a of the knob 1231 extends along the first direction to abut against the locking segment 1222 bb.

[0071] In the unlocked state, the long end 1231a of the knob 1231 extends along the thickness direction to slide along the sliding section 1222ba, wherein the first direction is perpendicular to the thickness direction.

[0072] In this embodiment, the size of the long end 1231a of the knob 1231 is larger than the size of the sliding section 1222ba along the first direction. In the locked state, the long end 1231a of the knob 1231 extends along the first direction to abut against the locking section 1222bb, so that the long end 1231a of the knob 1231 cannot enter the sliding section 1222ba to lock the guide rail 1222 to the current locking section 1222bb. In the case where the guide rail 1222 needs to be moved, the locking member 123 rotates to the unlocked state, the long end 1231a of the knob 1231 extends along the thickness direction to avoid the locking section 1222bb, and the knob 1231 can slide in the sliding section 1222ba, thereby moving to another locking section 1222bb. In this way, the locking and unlocking of the locking member 123 are achieved by using the cooperation of the long end 1231a of the knob 1231, the locking section 1222bb and the sliding section 1222ba, and the structure is simple and easy to implement.

[0073] It is understandable that the number of locking segments 1222bb may be the same as the number of locking positions, and each locking segment 1222bb corresponds to a locking position. Fig. 9 The number of locking segments 1222bb is two, and the number of locking positions is also two. The movable groove 1222b is generally in an I-shape.

[0074] In one embodiment, please refer to Figures 3 to 11 The guide rail 1222 includes two monomers 12221, and the monomer 12221 includes a longitudinal rod 122211 extending along the first direction and a transverse plate 122212 extending along the second direction. The longitudinal rod 122211 is formed with a guide groove 1222a extending along the first direction, and the transverse plate 122212 is connected to one end of the longitudinal rod 122211 along the first direction. The transverse plate 122212 is bent at one end away from the longitudinal rod 122211 along the second direction to form a hook end 122212a. The longitudinal rods 122211 of the two monomers 12221 are spaced apart along the second direction, and the hook ends 122212a of the transverse plates 122212 of the two monomers 12221 are interlocked, wherein the first direction, the second direction and the third direction are perpendicular to each other.

[0075] The hook ends 122212a of the horizontal plates 122212 of the two monomers 12221 interlock with each other, which means that the bent portion of one of the hook ends 122212a extends into the space defined by the bent portion of the other hook end 122212a, so that the two hook ends 122212a are hooked with each other (see Fig.10 ).

[0076] In this embodiment, the two monomers 12221 together constitute the guide rail 1222, and the two monomers 12221 can be quickly connected by interlocking the hook ends 122212a of the cross plates 122212 of the two monomers 12221, which is easy to operate and can effectively reduce the use of screws or bolts.

[0077] In one embodiment, the longitudinal rod 122211 includes a first guard plate and a second guard plate both extending in a first direction, the first guard plate is perpendicular to the thickness direction, the second guard plate is parallel to the thickness direction, and the second guard plate is connected to a side of the first guard plate away from the ventilation duct 122a in the second direction to jointly define the guide groove 1222a. The longitudinal rod 122211 has a simple structure, and the first guard plate can limit the filter screen 11 to prevent the filter screen 11 from slipping out of the ventilation duct 122a in the thickness direction.

[0078] In one embodiment, the movable groove 1222b is formed on the second guard plate.

[0079] In one embodiment, the single body 12221 may be an integrally formed structure. Exemplarily, the single body 12221 is a sheet metal structure.

[0080] The number of the movable grooves 1222b and the locking member 123 can be multiple, and each movable groove 1222b corresponds to a locking member 123. Exemplarily, in one embodiment, multiple movable grooves 1222b are arranged on the second guard plate at intervals along the first direction. In this way, the guide rail 1222 is more stably restricted in multiple areas in the first direction.

[0081] In one embodiment, the base 1221 includes two bases spaced apart along the second direction, the base includes a first plate and a second plate both extending along the first direction, the first plate is perpendicular to the thickness direction, the second plate is parallel to the thickness direction, and the second plate is connected to one side of the first plate close to the ventilation duct 122a along the second direction. The base has a simple structure and is easy to form.

[0082] The seat body 1221 may be detachably connected to the panel 121 , for example, the seat body 1221 and the panel 121 are connected via fasteners.

[0083] In one embodiment, the locking member 123 is rotatably connected to the second plate, and the first plate is connected to the panel 121 via a fastener.

[0084] The first plate body and the panel 121 may be connected by fasteners, which include but are not limited to screws or bolts.

[0085] In one embodiment, the base may be an integrally formed structure. Exemplarily, the base is a sheet metal structure.

[0086] In one embodiment, please refer to Figure 3 and Figure 4The maintenance panel assembly 1 includes a buckle 13, which is connected to the limit frame 122 to abut against the side of the filter 11 away from the panel 121 in the thickness direction. In other words, the two end surfaces of the filter 11 in the thickness direction are clamped between the buckle 13 and the panel 121, and the buckle 13 presses the filter 11 against the panel 121, which can not only prevent the filter 11 from falling out of the ventilation duct 122a, but also reduce the possibility of vibration or air leakage of the filter 11.

[0087] In one embodiment, please refer to Figures 7 to 9 An opening groove 122b opening toward the ventilation duct 122a is formed on the side of the limit frame 122 away from the panel 121 along the thickness direction. The buckle 13 includes a pressing plate 131 and a supporting leg 132. The pressing plate 131 is connected to the side of the supporting leg 132 close to the filter screen 11. The pressing plate 131 abuts against the filter screen 11, and the supporting leg 132 enters the opening groove 122b through the opening of the opening groove 122b.

[0088] In this embodiment, the pressing plate 131 abuts against the filter screen 11 to press the filter screen 11 against the panel 121 to limit the movement of the filter screen 11. The opening slot 122b opens toward the ventilation duct 122a, and the leg 132 can translate along the first direction through the opening of the opening slot 122b and enter the opening slot 122b, thereby realizing convenient installation of the buckle 13, which is simple to operate, does not require tools, and can effectively reduce the number of fasteners.

[0089] In one embodiment, please refer to Figures 7 to 9 A through hole 122c is formed on one side of the limit frame 122 away from the panel 121 in the thickness direction. There are two legs 132, one of which is a bent piece, and the other is a straight piece. One of the straight piece and the bent piece is inserted into the through hole 122c, and the other of the straight piece and the bent piece is inserted into the opening slot 122b. The portion of the bent piece located outside the ventilation duct 122a is bent toward the limit frame 122.

[0090] For example, the straight piece may be inserted into the through hole 122c, and the bent piece may be inserted into the open slot 122b. For another example, the bent piece may be inserted into the through hole 122c, and the straight piece may be inserted into the open slot 122b.

[0091] For example, when the buckle 13 is installed on the limiting frame 122, the straight piece can be first inserted into the through hole 122c, and then the bent piece can be translated from the opening of the opening slot 122b to the opening slot 122b along the first direction. The hole wall surface of the through hole 122c restricts the straight piece from moving in the first direction, and the bent piece restricts the buckle 13 from moving in the thickness direction, so that the buckle 13 is stably assembled on the limiting frame 122.

[0092] In this embodiment, the bent piece abuts against the limit frame 122 to prevent the buckle 13 from falling into the ventilation duct 122a along the thickness direction. The straight piece can reduce the difficulty of installation, and the hole wall surface of the through hole 122c can limit one of the straight piece and the bent piece from moving along a plane perpendicular to the thickness direction, such as a horizontal plane, further limiting the degree of freedom and improving the installation stability.

[0093] It should be noted that a straight sheet is a sheet-like structure extending in a straight line, while a bent sheet is a sheet-like structure extending along a curve.

[0094] In one embodiment, the through hole 122c and the opening slot 122b may be formed on the first guard plate.

[0095] In one embodiment, please refer to Figures 3 to 7 The number of the buckles 13 can be multiple, and the multiple buckles 13 are arranged on the monomer 12221, such as the first guard plate, at intervals along the first direction. Each buckle 13 can correspond to a through hole 122c and an open slot 122b.

[0096] In one embodiment, the buckle 13 may be an integrally formed structure. For example, the buckle 13 is a sheet metal structure.

[0097] The buckle 13 may be made of metal material. Exemplarily, the buckle 13 is made of highly elastic metal material.

[0098] In one embodiment, please refer to Figure 3 , Figure 4 and Figure 6 The maintenance plate 12 includes a blocking member 124. One end of the limit frame 122 along the first direction is formed with a draw-out opening 122d connected to the ventilation duct 122a. The filter 11 enters and exits the ventilation duct 122a through the draw-out opening 122d. The blocking member 124 shields at least a portion of the draw-out opening 122d. The filter 11 can be inserted into the ventilation duct 122a or pulled out of the ventilation duct 122a through the draw-out opening 122d. In this way, it is easy to install and remove the filter 11, so as to facilitate the cleaning or replacement of the filter 11. The blocking member 124 shields part or all of the draw-out opening 122d to prevent the filter 11 from slipping out of the draw-out opening 122d.

[0099] Exemplarily, the blocking member 124 may be detachably connected to the limiting frame 122. For example, the blocking member 124 is snap-fitted to the limiting frame 122, connected by screws or bolts, and the like.

[0100] In one embodiment, please refer to Figure 3 , Figure 4 , Figure 5 and Fig. 9The limiting frame 122 is provided with positioning portions 122e on both sides along the second direction, and the blocking member 124 includes a baffle 1241 and two fixing hooks 1242. The two fixing hooks 1242 are respectively connected to the two ends of the baffle 1241 along the second direction. The baffle 1241 shields at least part of the pull-out opening 122d, and the fixing hooks 1242 hook the positioning portion 122e.

[0101] In this embodiment, the baffle 1241 is used to prevent the filter screen 11 from escaping from the ventilation duct 122a through the draw-out opening 122d. The fixing hook 1242 hooks the positioning portion 122e to detachably connect the blocking member 124 to the limiting frame 122, which can reduce the use of screws and bolts, and can complete the installation of the blocking member 124 without the aid of tools, which is convenient to operate.

[0102] In one embodiment, please refer to Figure 3 , Figure 4 , Figure 5 and Fig. 9 , the positioning portion 122e is formed with a positioning cavity penetrating along the first direction, and the fixing hook 1242 passes through the fixing cavity along the first direction and hooks the positioning portion 122e. Exemplarily, during the installation process, the fixing hook 1242 passes through the fixing cavity along the first direction and hooks the positioning portion 122e, and the blocking member 124 can be detachably assembled to the limiting frame 122. In the case where the blocking member 124 needs to be removed, force can be applied to make the fixing hook 1242 release the positioning portion 122e and escape from the positioning cavity in the opposite direction along the first direction.

[0103] In one embodiment, please refer to Figures 3 to 6 The maintenance panel assembly 1 includes a frame 14, which is surrounded by a mounting opening 14a. One end of the panel 121 is rotatably connected to the frame 14, and the panel 121 and the frame 14 are detachably connected to cover the mounting opening 14a. The maintenance panel assembly 1 can be fixed by fixing the frame 14 to other components, for example, the frame 14 can be fixed to the duct machine 2. When the filter 11 needs to be maintained, the panel 121 can be unlocked from the frame 14, and the panel 121 is rotated relative to the frame 14 to have an open state (see Figure 6 ) and the closed state (see Figure 4 ), the panel 121 rotates relative to the frame 14 to achieve opening and closing, which can reduce the height of the panel 121, thereby reducing the height of the filter 11 to facilitate the operation of the operator.

[0104] In one embodiment, the detachable connection between the panel 121 and the frame 14 may be a snap connection or a connection via a fastener, which includes but is not limited to screws or bolts.

[0105] In one embodiment, please refer to Fig.12The panel 121 is formed with a cutting line 121b, and the cutting line 121b encloses a cutting area 121c, and the limit frame 122 is located in the cutting area 121c. The cutting line is convenient for the operator to cut the cutting area. Exemplarily, when the panel of the shell of the duct machine 2 is damaged or other panels of the shell need to be replaced, the cutting area 121c can be cut off from the panel 121, so that the cutting area 121c can replace the panel of the shell, for example, the cutting area 121c replaces the bottom plate of the shell, thereby improving the versatility of the maintenance panel assembly 1.

[0106] In one embodiment, please refer to Figure 3 and Figure 4 The number of the limiting frames 122 and the vents 121a are both multiple, and the multiple limiting frames 122 are spaced apart, and each limiting frame 122 corresponds to a vent 121a. The air intake is increased by multiple vents 121a, and the area of ​​each vent 121a is moderate to match the area size of the existing filter 11.

[0107] In some embodiments, the number of the limiting frames 122 and the number of the ventilation openings 121 a are both one.

[0108] The number of the vents 121a can be the same as the number of the indoor air inlets 2a. For example, the number of the indoor air inlets 2a is two, and the number of the vents 121a, the limit frame 122 and the filter 11 can all be two. The spacing between the two vents 121a can be the same as the spacing between the two indoor air inlets 2a.

[0109] The number of ventilation openings 121a may be different from the number of indoor air inlets 2a. For example, one indoor air inlet 2a corresponds to a plurality of ventilation openings 121a.

[0110] The form of the vent 121a is not limited. For example, in one embodiment, the vent 121a can be a single opening with a larger area. Figure 2 and Figure 4 The ventilation opening 121a may include a plurality of through holes. Thus, the area of ​​a single through hole is moderate, which can reduce the risk of foreign objects extending into the ventilation duct 122a through the through hole.
