Description

Technical Field

[0001] This utility model relates to the technical field of air conditioner products, specifically to an air inlet mesh structure for an air conditioner. Background Technology

[0002] Air conditioners draw in indoor air through the intake port, exchange heat with the refrigerant, and then discharge the air through the exhaust port. In floor-standing air conditioners, the exhaust port can be located at the front or side of the cabinet, while the intake port can be located at the rear. Floor-standing air conditioners are typically arranged so that the exhaust port faces the interior wall, so the intake port located at the rear of the cabinet is positioned facing the wall surface or edge of the interior space. Therefore, due to the size or weight of the product and the arrangement of the refrigerant pipes, it is difficult to change the installation location of floor-standing air conditioners.

[0003] Meanwhile, to improve indoor air quality, a filter is installed at the air intake of the air conditioner to filter the air entering the air conditioner. After a period of use, the filter needs to be cleaned. However, the existing filter is installed at the back of the air conditioner casing. Since the back of the air conditioner casing is usually attached to the indoor wall, the space behind the air conditioner casing is limited, making it very inconvenient to clean the filter directly. Usually, it is necessary to move the air conditioner (standing air conditioner) or disassemble the air conditioner (wall-mounted air conditioner) before cleaning the filter. Cleaning the filter at the air intake of the air conditioner is not very convenient. Utility Model Content

[0004] In view of the defects existing in the prior art, the purpose of this utility model is to provide an air inlet mesh cover structure for an air conditioner, so as to solve the problem of poor cleaning operation of the filter at the air inlet of the existing air conditioner due to the limited operating space.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This application provides an air inlet mesh structure for an air conditioner. The air inlet mesh structure is installed on the housing of the air conditioner. An air inlet is provided on the back of the housing. The structure includes an air inlet mesh, multiple filter modules, and a filter cleaning assembly. The air inlet mesh is installed on the back of the housing at a position corresponding to the air inlet. The multiple filter modules are evenly installed on the air inlet mesh. The filter cleaning assembly is slidably mounted on the back of the housing and is used to clean the multiple filter modules.

[0007] Furthermore, the filter cleaning assembly includes a filter cleaner, a moving guide for guiding the lifting and lowering movement of the filter cleaner, and a power supply device for supplying power to the filter cleaner, wherein the filter cleaner slides up and down along the moving guide.

[0008] Furthermore, the filter cleaner includes a cleaner housing forming the external shape, a movable gear rotatably mounted in the cleaner housing and moving the cleaner housing, a gear motor disposed in the cleaner housing and rotating the movable gear, a guide roller rotatably mounted in the cleaner housing and guiding the movement of the cleaner housing, and an agitator rotatably mounted on one side of the cleaner housing and removing foreign objects trapped in the filter module by rotation.

[0009] Furthermore, the filter cleaner may also include a dust collector for collecting foreign objects separated from the sweeper housing, a connecting housing disposed within the sweeper housing and forming a space for insertion into the dust collector, a suction fan for drawing foreign objects separated from the filter module toward the dust collector by the rotation of the agitator, and a suction fan motor for driving the suction fan.

[0010] Furthermore, the sweeper housing includes a bottom cover and an outer cover, the outer cover being disposed at the rear of the bottom cover, and the interior of the outer cover and the bottom cover forming a space for accommodating a dust collector.

[0011] Furthermore, the moving guide includes a guide rail for guiding the movement of the filter cleaner, an upper movement limiting part for restricting the upward movement of the filter cleaner along the guide rail, and a lower movement limiting part for restricting the downward movement of the filter cleaner along the guide rail.

[0012] Furthermore, the guide rail includes an upper guide rail and a lower guide rail, with the upper guide rail disposed at the upper rear of the housing.

[0013] Furthermore, the guide rail also includes a gear guide rail and a roller guide rail, the gear guide rail having teeth to mesh with the movable gear of the filter cleaner, and the roller guide rail for moving the guide roller of the filter cleaner.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. By adopting the air inlet mesh structure of the air conditioner described above, a filter cleaning assembly that moves vertically is arranged on the housing at the position corresponding to the filter module. The filter cleaning assembly has a structure that removes foreign objects stuck in the filter module by rubbing and rotating the agitator against the filter module. Since the foreign objects stuck in the filter module fall off due to the friction of the agitator, it has the advantage of being able to cleanly manage the filter module. As a result, the air with foreign objects removed is discharged through the outlet, thereby having the advantage of being able to comfortably maintain the indoor space.

[0016] 2. The guide rollers that allow the filter cleaner to make close contact with the filter module are movably mounted on the guide rail, so that the filter cleaner can move stably in the vertical direction of the filter module, and the agitator can maintain friction with the filter module, so that the filter module can be kept clean.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0031] See appendix Figure 1 To be continued Figure 13 As shown, this embodiment provides an air inlet grille structure for an air conditioner, which is installed on the air conditioner.

[0032] The air conditioner includes a housing assembly I, a door assembly II, a fan assembly III, a heat exchange assembly IV, and an air inlet grille structure. The air inlet grille includes an air inlet grille 622, multiple filter modules 62a, 62b, 62c, and 62d, and a filter cleaning assembly VI. The air inlet grille 622 is installed on the back of the housing corresponding to the air inlet position. The multiple filter modules 62a, 62b, 62c, and 62d are evenly installed on the air inlet grille. The filter cleaning assembly VI is slidably mounted on the back of the housing and is used to clean the multiple filter modules 62a, 62b, 62c, and 62d. The fan assembly III is arranged inside the housing assembly I to create airflow. The heat exchange assembly IV is used to exchange heat between the air flowing through the fan assembly III and the refrigerant. The filter cleaning assembly VI is used to filter the air flowing into the inside of the housing assembly I. The filter cleaning assembly VII is used to remove foreign objects present on one side of the filter cleaning assembly VI. The humidification assembly V is used to exhaust the humidified air to the outside of the housing assembly I.

[0033] Side discharge components 14a and 14b are provided on the left and right sides of the housing assembly I. The side discharge components 14a and 14b are disposed between the upper housing 11 and the door assembly II and form a side outlet 141. The filter cleaning assembly VI is installed in the side outlet 141. Air is discharged from the side outlet 141 at the part that forms the suction port 111.

[0034] Multiple filter modules 62a, 62b, 62c and 62d are disposed on the left and right sides of the upper rear side of the housing 11, and a guide rail 711 for guiding the movement of the filter cleaner 72 is disposed between the multiple filter modules 62a, 62b, 62c and 62d, which are disposed on the aforementioned left and right sides of the rear side of the housing 11.

[0035] A guide rail 711 for guiding the movement of the filter cleaner 72 can be arranged at the rear of the housing 11. The guide rail 711 is configured to protrude rearward from the center of a plurality of filter modules 62a, 62b, 62c and 62d, which are located on the left and right sides of the rear of the housing 11.

[0036] The base 12 is located on the lower side of the upper cabinet 11. The base 12 has an inner space for arranging a water tank 51 and a heating element 52, which are structures serving as the humidification assembly V. A power supply 73, on which the power cord 731 connected to the filter cleaning assembly VII is wound, can be located inside the base 12. A portion of the lower housing 13 and the side discharge members 14a and 14b can be located on the outer periphery of the base 12. The base 12 may have a power cord through-hole 133 through which the power cord 731 connected to the filter cleaning assembly VII passes, and a humidification flow path through-hole (not shown) through which the humidification flow path pipe 54 of the humidification assembly V passes.

[0037] See attached document Figure 2The filter cleaning assembly VI according to this embodiment includes filter modules 62a, 62b, 62c, and 62d, which are configured to remove foreign objects from the air drawn into the intake port 111. The filter cleaning assembly VI can be positioned at the intake port 111, or it can be positioned on the outer side of the lateral surface of the upper housing 11. The filter cleaning assembly VI according to this embodiment may include filter modules 62a, 62b, 62c, and 62d, a filter mounting member (not shown), and a moving member (not shown). Filter modules 62a, 62b, 62c, and 62d are mounted on the filter mounting member, and the moving member changes the position of the filter mounting member. In other words, filter modules 62a, 62b, 62c, and 62d can be positioned from a first position to a second position. In the first position, filter modules 62a, 62b, 62c, and 62d are positioned at the inlet 111 formed at the rear of the upper housing 11. In the second position, filter modules 62a, 62b, 62c, and 62d are positioned at the inlet 111, and the filter cleaner 72 forms a movable surface thereon. The first filter modules 62a and 62b can be positioned to cover the left side of the suction inlet 111, or they can be positioned on the left side of the left side surface of the upper housing 11. When both the first filter modules 62a and 62b and the second filter modules 62c and 62d are located at the inlet 111, the second filter modules 62c and 62d can be positioned to cover the right side of the inlet 111, or they can be positioned on the right side of the right side surface of the upper housing 11 to form a surface on which the filter cleaner 72 can move. When the first filter modules 62a, 62b, 62c, and 62d are detachably located at the filter mounting member, the second filter modules 62c and 62d can be located at the filter mounting member. The filter modules 62a, 62b, 62c, and 62d can filter foreign objects from the air flowing into the intake 111. According to this embodiment, the filter modules 62a, 62b, 62c, and 62d may include a pre-filter 621 for filtering large dust particles from the air flowing into the intake 111, a dust collection filter section (not shown) for collecting air particles ionized by the ionization section and filtering the air, and a deodorizing filter section (not shown) for removing odors from the air.

[0038] According to this embodiment, filter modules 62a, 62b, 62c, and 62d may further include a pre-filter 621 mounted on an air inlet grille 622. Multiple intake holes are formed in the air inlet grille 622 along the mounting direction of the pre-filter 621. Vertical ribs 6221 and horizontal ribs 6222 can form a mesh shape with each other, thereby enhancing the rigidity of the air inlet grille 622. The pre-filter 621 can be formed in the form of a mesh to filter large foreign objects in the air introduced into filter modules 62a, 62b, 62c, and 62d. When the filter cleaner 72 of the filter cleaning assembly VII described below is positioned at the lowest point of its movement range that allows it to move along the guide rail 711, the lower end 60a of the filter cleaning assembly VI is positioned above the upper end 72a of the filter cleaner 72. Here, the lower end 60a of the filter cleaning assembly VI may refer to the portion positioned further downside among the lower ends of the filter mounting members 61a and 61b and the lower ends of the filter modules 62b and 62d positioned downside.

[0039] Continue to refer to the appendix Figure 2 As shown, when the filter cleaner 72 is positioned at the lowermost end of its movement range that allows it to move along the guide rail 711, the arrangement of the filter mounting members of the filter cleaning assembly VII, on which filter modules 62a, 62b, 62c, and 62d are mounted, can be changed. This allows the filter cleaning assembly VII to move vertically along the rear surface of the filter cleaning assembly VI, and to remove foreign objects from the outside of the filter cleaning assembly VI. The filter cleaning assembly VII moves rearward toward the filter cleaning assembly VI and includes a filter cleaning machine 72 for removing foreign objects trapped in the filter cleaning assembly VI, a movement guide 71 for guiding the movement of the filter cleaning machine 72, and a power supply device 73 for supplying power to the filter cleaning machine 72.

[0040] See attached document Figure 4 To be continued Figure 7As shown, the moving guide 71 guides the movement of the filter cleaner 72 within its range of motion. The moving guide 71 is disposed at the rear of the housing assembly I. The moving guide 71 includes a guide rail 711 for guiding the movement of the filter cleaner 72, an upper movement limiting portion 712 for limiting the upward movement of the filter cleaner 72 along the guide rail 711, and a lower movement limiting portion 713 for limiting the downward movement of the filter cleaner 72 along the guide rail 711. The guide rail 711 is arranged elongated in the vertical direction on the rear side of the upper housing 11. The guide rail 711 is disposed between a pair of filter cleaning assemblies VI arranged on the left and right sides at the rear of the upper housing 11. The guide rail 711 may include an upper guide rail 711a and a lower guide rail 711b. The upper guide rail 711a is located behind the upper housing 11, and the filter modules 62a, 62b, 62c, and 62d are located behind the upper housing 11. The lower guide rail 711b is located below the upper guide rail 711a and behind the lower housing 13. The upper guide rail 711a and the lower guide rail 711b may be formed as separate structures. However, this is one embodiment, and the upper guide rail 711a and the lower guide rail 711b may also be formed as a single structure. Furthermore, the upper guide rail 711a can be divided into multiple guide rails, and the lower guide rail 711b is located at the rear of the lower housing 13. The length of the lower guide rail 711b can be longer than the vertical length of the filter cleaner 72. The guide rail 711 includes gear guide rails 7111a and 7111b and roller guide rails 7112a and 7112b. The gear guide rails 7111a and 7111b are threaded to engage with the movable gears 725a and 725b of the filter cleaner 72. The roller guide rails 7112a and 7112b allow the guide rollers 726a1, 726a2, 726b1 and 726b2 of the filter cleaner 72 to move.

[0041] Furthermore, a guide groove 7113 is formed in the guide rail 711, and a power line 731 connected to the filter cleaner 72 is disposed in the guide groove 7113. The guide rail 711 has a guide groove 7113 formed on its rear side 711b, which is the opposite side of the front surface 711a. Gear guide rails 7111a and 7111b, and roller guide rails 7112a and 7112b are disposed on two side surfaces connecting the front surface 711a and the rear surface 711b. Furthermore, the moving gears 725a and 725b meshing with the gear guide rails 7111a and 7111b may have the shape of pinions. The gear guide rails 7111a and 7111b are elongated along the vertical direction in the portions where filter modules 62a, 62b, 62c, and 62d are disposed. The gear guide rails 7111a and 7111b may be formed on both sides of the guide rail 711. Roller tracks 7112a and 7112b have rib-like structures protruding to both sides from the rear end of guide rail 711. Roller tracks 7112a and 7112b are located behind gear tracks 7111a and 7111b. Roller tracks 7112a and 7112b are formed to protrude more to both sides than the height of the threads formed on gear tracks 7111a and 7111b.

[0042] Gear rails 7111a, 7111b and roller rails 7112a, 7112b are arranged on both sides of rail 711. The pair of roller rails 7112a, 7112b are positioned further rearward than the pair of gear rails 7111a, 7111b. The pair of roller rails 7112a, 7112b protrude laterally from the pair of gear rails 7111a, 7111b. Therefore, when the indoor unit according to this embodiment is viewed from the rear, the gear rails 7111a and 7111b may have a structure that is obscured by the roller rails 7112a and 7112b. A guide groove 7113 forms a space for arranging a power cord 731 connected to the filter vacuum cleaner 72. The guide groove 7113 is recessed forward from the rear surface 7111b of the rail 711. The guide groove 7113 is formed elongated along the vertical direction of the guide rail 711. The upward movement limiting portion 712 can limit the upward movement of the filter cleaner 72. The upward movement limiting unit 712 may include a magnetic force generating unit 7121 that generates magnetic force. The magnetic force generating unit 7121 may use a permanent magnet that generates magnetic force. The magnetic force generating unit 7121 may be positioned at a predetermined downward distance from the upper end of the guide rail 711. The magnetic force generating unit 7121 may be disposed in the guide groove 7113 of the guide rail 711. The upward movement limiting portion 712 includes a top plate 7122, which is disposed at the upper end of the guide rail 711 to limit the upward movement of the filter cleaner 72. The upper plate 7122 may be disposed at the upper end of the guide rail 711 and may contact the upper end of the filter cleaner 72.

[0043] However, when the Hall sensor 7212 malfunctions, the movement of the filter cleaner 72 may be restricted by the upper end plate 7122, and a downward movement restriction portion 713 is provided at the lower end of the guide rail 711 to restrict the downward movement of the filter cleaner 72, and a lower plate 7131 is provided at the lower end of the guide rail 711 to restrict the downward movement of the filter cleaner 72. The lower end plate 7131 may be provided at the lower end of the guide rail 711 and may contact the lower part of the filter cleaner 72. The lower end plate 7131 forms a surface perpendicular to the guide rail 711 at the upper end of the guide rail 711. The lower end plate 7131 is arranged on the upper side of the rear protruding cover 131 formed in the lower housing 13 and has a structure that protrudes in two directions from the guide rail 711 arranged on the two side surfaces of the guide rail 711. However, the lower end plate 7131 has a lower end plate groove 7131a, through which the power cable 731 passes toward the lower side of the guide groove 7113 formed in the guide rail 711. The lower end plate groove 7131a is formed on the lower side of the guide groove 7113. The lower end plate groove 7131a connects the guide groove 7113 to the power cable hole 1312 formed on the upper side of the rear protruding cover 131 of the lower housing 13. A fastening groove 7114 is formed on the guide rail 711 for fastening other fastening devices. The fastening groove 7114 extends forward from the guide groove 7113 formed at the rear of the guide rail 711. An electrode hole 7115 can be formed in the guide rail 711, forming a space in which an electrode (not shown) is arranged to ionize molecules in the air by discharge. Electrode holes 7115 are formed in the forward direction of guide grooves 7113 formed behind guide rails 711. Electrodes can be disposed in electrode holes 7115. Electrodes can be configured not to protrude outward from guide grooves 7113. Referring below... Figures 8 to 13 The filter cleaner according to this embodiment is described, wherein the filter cleaner 72 is movably disposed at the rear of the upper housing 11. The filter cleaner 72 can move up and down along the guide rail 711, and can remove foreign objects stuck in the pre-filter 621 of the filter modules 62a, 62b, 62c and 62d in the front, rear, left, right, up and down directions depending on whether the filter cleaner 72 is disposed at the rear of the upper housing 11 or the lower housing 13.

[0044] The filter cleaner 72 includes housings 721 and 722 forming the external shape, movable gears 725a and 725b rotatably mounted in and moving the housings 721 and 722, gear motors 7251a and 7251b disposed within the housings 721 and 722 and rotating the movable gears 725a and 725b, guide rollers 726a1, 726a2, 726b1 and 726b2 rotatably mounted in and guiding the movement of the housings 721 and 722, agitators 723a and 723b rotatably mounted on one side of the housings 721 and 722 and removing foreign objects trapped in the filter modules 62a, 62b, 62c and 62d by rotation, and agitators 723a and 723b.

[0045] The filter cleaner 72 may also include a dust collector 727 for receiving foreign matter separated from housings 721 and 722, a connecting housing 728 disposed within housings 721 and 722 and forming a space for inserting the dust collector 727, a suction fan 729 for drawing foreign matter separated from filter modules 62a, 62b, 62c and 62d toward the dust collector 727 by rotation of agitators 723a and 723b, and a suction fan motor 7291 for operating the suction fan 729.

[0046] The housings 721 and 722 include a base cover 721 and an outer cover 722. The base cover 721, when mounted on the moving guide 71, is positioned facing the filter modules 62a, 62b, 62c, and 62d. The outer cover 722 is disposed at the rear of the base cover 721 and is coupled to the base cover 721 to form a space within the base cover 721 for housing the dust collector 727. The outer cover 722 may have a plate shape parallel to the filter modules 62a, 62b, 62c, and 62d. When the filter cleaner 72 moves at the rear of the filter modules 62a, 62b, 62c, and 62d, the distance between the base cover 721 and the filter modules 62a, 62b, 62c, and 62d remains constant. When the filter cleaner 72 is movably disposed in the guide rail 711, a guide rail groove 7211 is formed in the base cover 721, and the guide rail 711 is inserted into the guide rail groove 7211. The base cover 721 has a plate-like shape overall, and recesses can be formed in the portions where guide rail grooves 7211 and edge grooves 7213a and 7213b are formed. The guide rail groove 7211 can be formed at the center dividing the base cover 721 into left and right sections. Parts of guide rollers 726a1, 726a2, 726b1, and 726b2 mounted on the base cover 721, as well as movable gears 725a and 725b, can be exposed in the guide rail groove 7211, such that the guide rail groove 7211 is formed on the base cover 721 in the vertical direction. A Hall sensor 7212 is disposed in the guide rail groove 7211 to detect the magnetic force of the magnetic force generating part 7121 disposed on the guide rail 711.

[0047] The Hall sensor 7212 can output a signal when it senses the magnetic force of the magnetic force generating unit 7121. When the Hall sensor 7212 senses the magnetic force of the magnetic force generating unit 7121, the filter cleaner 72 can stop moving. In the base cover 721, a pair of throttling grooves 7213a and 7213b are formed on the left and right sides of the guide rail groove 7211. In the base cover 721, a first pressure-holding groove 7213a is formed on the left side of the guide rail groove 7211, and a second pressure-holding groove 7213b is formed on the right side of the guide rail groove 7211, and each of the pair of pressure-holding grooves 7213a and 7213b forms a groove that is recessed rearward from the base cover 721. The base cover 721 includes an edge surface 72131, and the edge surface 72131 forms a groove that is recessed rearward from the base cover 721 in the portion forming the edge grooves 7213a and 7213b. The base cover 721 includes a circumferential surface 72131 of the pressure-holding members, formed around the outer periphery of the pressure-holding members 723a and 723b at portions forming pressure-holding grooves 7213a and 7213b, and a mounting surface 72134. The circumferential surface 72131 is rotatably mounted on the mounting surface 72134, and the circumferential surface 72131 may have a U-shaped shape protruding in the rearward direction. Connecting holes 72132a and 72132b, formed to communicate with the dust collector 727, are formed on one side of the agitator peripheral surface 72131. The connecting holes 72132a and 72132b are located in the left-right direction of the agitator peripheral surface 72131. The connecting holes 72132a and 72132b are formed along the length of the pressure-holding members 723a and 723b, which are formed along the rotation axis of the pressure-holding members 723a and 723b.

[0048] Dust particles 72135a and 72135b used to remove foreign matter adhering to the blades 7232 of the agitators 723a and 723b can be disposed on one side of the peripheral surface 72131 of the agitator. The dust particles 72135a and 72135b are disposed on one side of the connecting holes 72132a and 72132b on the peripheral surface 72131 of the agitator. When the agitators 723a and 723b rotate, the dust particles 72135a and 72135b can be configured to rub against the blades 7232 of the agitators 723a and 723b. The dust particles 72135a and 72135b can remove foreign matter adhering to the agitators 723a and 723b through friction with the agitators 723a and 723b.
