Description

Technical Field

[0001] This application relates to the field of air conditioning technology, specifically providing a purification device and an indoor air conditioning unit. Background Technology

[0002] With social development and improved living standards, indoor air quality has become a major concern. Especially during hot or cold seasons, air conditioning systems are almost indispensable for indoor air conditioning. However, prolonged use of air conditioning with doors and windows closed can lead to poor indoor ventilation, increasing the risk of indoor air pollution and posing a threat to the health of residents. Therefore, developing effective indoor air purification technologies is of great significance for improving the performance of air conditioning systems and enhancing indoor air quality.

[0003] In related technologies, an adsorption filter is installed at the air inlet of the indoor unit of an air conditioner to fix dust and other impurities in the air onto the surface of a specific material, thereby purifying the air. However, adsorption filters cannot purify harmful gases flowing through the air. Utility Model Content

[0004] This application aims to solve the aforementioned technical problem, namely, the problem that indoor air conditioning units are unable to effectively purify harmful gases in the air.

[0005] In a first aspect, this application provides a purification device, detachably disposed within the casing of an indoor air conditioning unit, and arranged at least corresponding to a portion of the air inlet of the indoor air conditioning unit; the purification device includes: a first cover having a first side plate facing a portion of the air inlet, the first side plate having a windward opening; a second cover, which is mutually abutted with the first cover and together encloses an installation space, the second cover having a second side plate arranged opposite to the first side plate, the second side plate having an air outlet opening; a first locking member and a second locking member, respectively disposed at two ends along the length of the first side plate, and at least one of the first locking member and the second locking member being slidable relative to the first side plate, the first locking member and / or the second locking member being in an extended state and configured to be inserted into the casing; and a purification component disposed within the installation space, the purification component being configured to decompose formaldehyde in the air flowing from the windward opening to the air outlet opening and convert ozone in the air into oxygen.

[0006] When the above technical solution is adopted, the first and second locking components can be used to install the docked first and second covers onto the housing, and at least some of the air inlets on the housing are arranged accordingly. In this way, through the air inlets and air outlets respectively provided on the first and second covers, some of the air entering the housing can pass through the purification components, thereby decomposing formaldehyde in the air and converting ozone in the air into oxygen and water, reducing the content of harmful gases in the air, and improving the cleanliness and quality of the air.

[0007] In an optional embodiment of the above-mentioned purification device, the purification component is provided with a plurality of flow holes, each of the flow holes sharing a hole wall with the adjacent flow holes, and the flow holes extending from the windward opening to the air outlet opening; wherein, the surface of the hole wall of the flow holes is coated with a catalyst layer.

[0008] By setting multiple flow holes and making adjacent flow holes share the same hole wall, air circulation can be ensured and the contact area between air and the purification component can be effectively increased. The catalytic layer coated on the surface of the flow hole wall can decompose formaldehyde and promote the conversion of ozone into oxygen and water, thereby improving air quality.

[0009] In an optional embodiment of the above-mentioned purification device, the first cover has a first peripheral portion located at both ends in its own length direction; the second cover has a second peripheral portion that is connected to the first peripheral portion; a first mounting post is fixed on each of the two second peripheral portions, the first mounting post extends along the length direction of the second cover and is inserted into the housing, and the first mounting post and the corresponding first locking member / second locking member are located at both ends in the width direction of the first cover.

[0010] The first mounting post allows for the initial connection between the purification device and the housing; furthermore, the first and second locking components enable the fixed installation of the purification device and the housing.

[0011] In an optional embodiment of the above-described purification device, the first locking member includes at least: a main body portion slidably disposed on the outer side of the first side plate; a second mounting post, bent and connected to the main body portion via a connecting portion and having the same extending direction as the first mounting post, the second mounting post being able to pass through the first peripheral portion and / or the second peripheral portion; when the first locking member slides along the extending direction, the second mounting post at least partially extends to the outside of the mounting space and is inserted into the housing; the second locking member is configured as a fixed shaft extending along the length direction of the second mounting post and fixed to the first peripheral portion and / or the second peripheral portion; or, the second locking member is configured to have the same structure as the first locking member.

[0012] By setting a second mounting post with the same extension direction as the first mounting post, the first locking member can extend out of the mounting space to be inserted and fixed with the housing when it slides in the extension direction, and can slide at least partially into the mounting space in the retraction direction to unlock from the housing; thus ensuring the detachable installation of the purification device.

[0013] Meanwhile, when the second locking component is a fixed shaft, it can achieve more stable fixing of the purification device; when the structure of the second locking component is the same as that of the first locking component, it can achieve more convenient and faster disassembly and assembly of the purification device.

[0014] In an optional embodiment of the above-mentioned purification device, a first through hole is provided on the first peripheral portion, and a second through hole is provided on the second peripheral portion that mates with the first through hole. The first through hole and the second through hole together form an outlet hole through which the second mounting post passes.

[0015] In this way, the extension of the second mounting post can be guaranteed, and the stability of its movement can also be ensured, preventing easy displacement or loosening due to external forces during use. Furthermore, the through-hole design effectively reduces friction between the second mounting post and the first and / or second periphery, thereby improving the smoothness of the sliding of the first locking member.

[0016] In an optional embodiment of the above-mentioned purification device, a guide assembly is further included. The guide assembly includes: a guide slide rail, which is arranged through the main body and extends along the length direction of the first cover; and a guide post, which is disposed on the outer side of the first side plate and inserted into the guide slide rail. When the first locking member slides in the extension direction or the retraction direction, the guide slide rail moves relative to the guide post in the length direction of the first cover.

[0017] The design of the guide component further optimizes the sliding process of the first locking element. When the first locking element slides in the extension or retraction direction, the guide rail moves relative to the limiting post, thereby achieving precise guidance. The cooperation between the two not only improves the ease of operation but also avoids installation failures caused by sliding deviations, thus enhancing installation accuracy.

[0018] In an optional embodiment of the above-mentioned purification device, the guide column has a protrusion at one end away from the first side plate, and the main body is sandwiched between the protrusion and the first side plate.

[0019] By providing a protrusion at the end of the guide post away from the first side plate, the reliability of the structure can be further enhanced, and the main body can be effectively prevented from detaching from the first side plate during sliding.

[0020] In an optional embodiment of the above-mentioned purification device, the guide assembly further includes: a stop plate disposed on the outer side of the first side plate and spaced apart from the guide post; the stop plate is configured to abut against the corresponding main body portion to achieve a stop engagement when the first locking member slides in the retraction direction.

[0021] By setting the stop plate, when the first locking member slides in the retraction direction, it can abut against the corresponding main body to achieve a stop engagement, thereby providing a clear displacement limit when the first locking member is unlocked, avoiding excessive sliding and causing the second mounting post to detach from the second periphery and / or the first periphery, and preventing structural damage.

[0022] In an optional embodiment of the above-mentioned purification device, a limiting component is further included. The limiting component includes: two limiting posts disposed on the outer side of the first side plate and respectively located on both sides of the width direction of the main body; two sets of limiting grooves respectively disposed on both sides of the width direction of the main body and recessed towards each other, each set of limiting grooves including at least a first groove and a second groove that are smoothly connected; when the first locking member slides along the extension direction or the retraction direction, the limiting groove moves relative to the corresponding limiting post so that the first groove or the second groove engages with the limiting post.

[0023] When the first locking member extends or retracts, the limiting groove moves relative to the corresponding limiting post, causing the first or second groove to engage with the limiting post. This not only ensures the stability of the first locking member in the locked or unlocked position but also simplifies the user's operation and improves the overall user experience.

[0024] In a second aspect, this application provides an indoor air conditioning unit, comprising: a housing, an air inlet at the top, and at least two mounting plates fixedly connected to the housing at intervals along the length of the air inlet; and a purification device as described above, the purification device being disposed between the two mounting plates and interlocking with the mounting plates; wherein the purification device extends along the length of the air inlet and its upper end is located at any position in the width direction of the air inlet, the purification device is arranged obliquely from top to bottom toward the front panel of the housing, and a flow space communicating with at least a portion of the air inlet is enclosed between the purification device and a portion of the front panel.

[0025] With the above technical solution, the upper end of the purification device is located at any position in the width direction of the air inlet and is inclined downwards towards the front panel of the casing. This ensures that the purification device corresponds to at least part of the air inlet. The first and second locking members can be used to install the mated first and second covers onto the casing. Since the air inlet faces the air inlet, the air inlets and outlets respectively located on the first and second covers allow some of the air entering the casing to pass through the purification components, thereby decomposing formaldehyde in the air and converting ozone in the air into oxygen and water, reducing the content of harmful gases in the air, and improving air cleanliness and quality.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0045] Firstly, combining Figures 1 to 13 As shown, this application provides a purification device that is detachably installed inside the casing 10 of an air conditioner indoor unit and is arranged at least in part of the air inlet 11 corresponding to the air conditioner indoor unit.

[0046] The purification device includes a first cover 20, a second cover 30, a first locking member 40, and a purification component 50. The first cover 20 has a first side plate 21 facing a portion of the air inlet 11, and the first side plate 21 has an airflow opening 210. The second cover 30 is mated and fixedly connected to the first cover 20 to jointly enclose an installation space. The second cover 30 has a second side plate 31 arranged opposite to the first side plate 21, and the second side plate 31 has an air outlet opening 310. The first locking member 40 and the second locking member are respectively disposed at two ends along the length of the first side plate 21, and at least one of the first locking member 40 and the second locking member is slidable relative to the first side plate 21. When the first locking member 40 and / or the second locking member is in the extended state, it is configured to be inserted into the housing 10. The purification component 50 is disposed within the installation space and is configured to decompose formaldehyde in the air flowing from the airflow opening 210 to the air outlet opening 310 and convert ozone in the air into oxygen.

[0047] In this design, the purification device is installed inside the casing 10 of the indoor unit of the air conditioner, and is arranged at least corresponding to a portion of the air inlets 11. This allows for the purification of at least a portion of the air entering the casing 10, thereby removing formaldehyde and ozone from the air.

[0048] Optionally, the first cover 20 and the second cover 30 are joined together, jointly enclosing an installation space. A purification component 50 can be installed within this space. The first cover 20 has a first side plate 21 facing the air inlet 11, and the second cover 30 has a second side plate 31 opposite to the first side plate 21. Air can enter the installation space through the air inlet 210 and air outlet 310 respectively formed on the first side plate 21 and the second side plate 31. The purification component 50 purifies the air flowing through the purification device. The purification component 50 can decompose formaldehyde and convert ozone into oxygen and water.

[0049] Optionally, the first lid 20 and the second lid 30 are fixedly connected. The fixed connection can be either detachable or non-detachable.

[0050] Optionally, the first cover 20 includes a first peripheral portion 22 and a third peripheral portion arranged circumferentially around the first side plate 21. The first peripheral portion 22 and the third peripheral portion are connected sequentially. Specifically, the first peripheral portion 22 is located at both ends in the length direction of the first side plate 21, and the third peripheral portion is located at both ends in the width direction of the first side plate 21.

[0051] The second cover 30 includes a second peripheral portion 32 and a fourth peripheral portion arranged circumferentially around the second side plate 31. The second peripheral portion 32 and the fourth peripheral portion are connected in sequence, and the first peripheral portion 22 and the second peripheral portion 32 are mated together, as are the third peripheral portion and the fourth peripheral portion.

[0052] Specifically, the first peripheral portion 22 and the second peripheral portion 32 are glued together; the third peripheral portion and the fourth peripheral portion are glued together. In this way, the first lid 20 and the second lid 30 can be fixedly connected.

[0053] Optionally, the first peripheral portion 22 and the third peripheral portion are provided with slots 24 facing the second cover 30, and the second peripheral portion 32 and the fourth peripheral portion are provided with corresponding stepped portions 34, which are inserted into the corresponding slots 24 so that the first cover 20 and the second cover 30 are connected.

[0054] Alternatively, a first magnetic element is provided in the slot 24, and a second magnetic element is provided on the stepped portion 34. The first and second magnetic elements attract each other. In this way, the first lid 20 and the second lid 30 can be fixedly connected.

[0055] Alternatively, the first lid 20 and the second lid 30 may be fixedly connected by snap-fit ​​or other means.

[0056] Optionally, a first locking member 40 and a second locking member are provided on the first side plate 21. At least one of the first locking member 40 and the second locking member can slide relative to the first side plate 21. Thus, the first locking member 40 and / or the second locking member can slide in the extension direction or the retraction direction. When the first locking member 40 and / or the second locking member slide in a direction away from each other, that is, when they slide to the extension direction to the extension state, they can respectively be inserted into the housing 10.

[0057] Furthermore, when the first locking member 40 and / or the second locking member slide in a direction close to each other, i.e., in a retraction direction, they can be separated from the housing 10.

[0058] When the above technical solution is adopted, the first and second box covers 20 and 30 after docking can be installed on the housing 10 by the first locking member 40 and the second locking member, and are arranged at least corresponding to part of the air inlet 11 on the housing 10. In this way, by the air inlet 210 and air outlet 310 respectively provided on the first box cover 20 and the second box cover 30, part of the air entering the housing 10 can pass through the purification member 50, thereby decomposing formaldehyde in the air and converting ozone in the air into oxygen and water, reducing the content of harmful gases in the air, and improving the cleanliness and air quality of the air.

[0059] In an optional embodiment of the above-mentioned purification device, the purification component 50 is provided with a plurality of flow holes 51, each flow hole 51 sharing a hole wall with the adjacent flow holes 51, and the flow holes 51 extend from the windward opening 210 to the air outlet opening 310.

[0060] The surface of the flow passage 51 is coated with a catalyst layer.

[0061] By setting multiple flow holes 51 and ensuring that adjacent flow holes 51 share at least a portion of the hole wall, air circulation can be guaranteed and the contact area between air and the purification component can be effectively increased. The catalytic layer coated on the surface of the hole wall can decompose formaldehyde and promote the conversion of ozone into oxygen and water, thereby improving air quality.

[0062] Specifically, by setting multiple flow holes 51 and making adjacent flow holes 51 share the same hole wall, a honeycomb-like structure can be formed. The structure formed in this way has low wind resistance and has less impact on the heat exchange efficiency of the indoor unit of the air conditioner.

[0063] Optionally, the cross-sectional shape of the flow passage 51 is set to hexagonal.

[0064] Alternatively, the cross-sectional shape of the flow hole 51 can be set to a circle, triangle, quadrilateral, or other shapes.

[0065] Optionally, the main component of the catalyst layer is manganese oxide. Specifically, manganese oxide has multiple crystalline phases, which endow it with excellent redox properties. When formaldehyde molecules come into contact with the surface of manganese oxide, they are captured by its active sites. Subsequently, manganese oxide catalyzes the reaction between formaldehyde and oxygen in the air, completely decomposing formaldehyde into carbon dioxide and water. Simultaneously, manganese oxide can also convert ozone into oxygen, thus providing sufficient oxygen for the decomposition of formaldehyde, ensuring a more complete decomposition.

[0066] Alternatively, the main component of the catalyst layer can be other catalytic materials with the same function.

[0067] Optionally, both the first lid 20 and the second lid 30 are coated with a catalyst layer.

[0068] Optionally, the surfaces of the first locking member 40 and the second locking member are also coated with a catalytic layer.

[0069] In an optional embodiment of the above-mentioned purification device, the first cover 20 has a first peripheral portion 22 located at both ends in its own length direction; the second cover 30 has a second peripheral portion 32 that is connected to the first peripheral portion 22.

[0070] Each of the two second peripheral portions 32 is fixed with a first mounting post 33. The first mounting post 33 extends along the length of the second cover 30 and is inserted into the housing 10. The first mounting post 33 and the corresponding first locking member 40 / corresponding second locking member are located at both ends in the width direction of the purification device.

[0071] The first mounting post 33 enables the initial connection between the purification device and the housing; furthermore, the first locking member 40 and the second locking member enable the fixed installation of the purification device on the housing 10.

[0072] Specifically, the two ends in the width direction of the purification device refer to the two ends in the width direction of the first cover 20, which are also the two ends in the width direction of the second cover 30. One first mounting post 33 corresponds to and engages with the first locking member 40; the other first mounting post 33 corresponds to and engages with the second locking member, thereby realizing the installation of the purification device. When installing the purification device, first insert the first mounting post 33 into the housing 10; then place the purification device in the installation position, and then slide the first locking member 40 and / or the second locking member in the extension direction to engage with the housing 10. When disassembling the purification device, first slide the first locking member 40 and / or the second locking member in the retraction direction to separate it from the housing 10, and then separate the first mounting post 33 from the housing 10.

[0073] Furthermore, when the second locking member is a fixed shaft, a portion of the fixed shaft can be fixed to the first peripheral portion 22, and the other portion of the fixed shaft can be fixed to the second peripheral portion 32. When the first cover 20 and the second cover 30 are mated, the two portions of the fixed shaft are mated.

[0074] In an optional embodiment of the above-described purification device, the first locking member 40 includes at least a main body 41 and a second mounting post 42. The main body 41 is slidably disposed on the outer side of the first side plate 21. The second mounting post 42 is bent and connected to the main body 41 via a connecting portion 43 and extends in the same direction as the first mounting post 33. The second mounting post 42 can pass through the first peripheral portion 22 and / or the second peripheral portion 32. When the first locking member 40 slides in the extension direction, the second mounting post 42 at least partially extends to the outside of the mounting space and is inserted into the housing 10. The second locking member is constructed as a fixed shaft extending along the length direction of the second mounting post 42 and is fixed to the first peripheral portion 22 and / or the second peripheral portion 32; or, the second locking member is constructed to have the same structure as the first locking member 40.

[0075] By setting a second mounting post 42 that extends in the same direction as the first mounting post 33, the first locking member 40 can extend out of the mounting space under the action of the main body 41 when it slides in the extension direction, so as to be inserted and fixed with the housing 10; in addition, the two second mounting posts 42 can at least partially move into the mounting space when the first locking member 40 slides in the retraction direction, so as to unlock from the housing 10; thereby ensuring the detachable installation of the purification device.

[0076] Furthermore, if the second locking member is a fixed shaft, after fixing the first mounting post 33, the second locking member is first inserted into the housing 10, and then the first locking member 40 is slid along the extension direction to achieve a more stable fixation of the purification device.

[0077] If the second locking member has the same structure as the first locking member 40, the first locking member 40 and the second locking member can be slid along the extension direction to achieve a fixed connection between the purification device and the housing 10.

[0078] Since the main body 41 is slidably disposed on the outer side of the first side plate 21, the main body 41 and the second mounting post 42 are bent and connected by a connecting part 43. The second mounting post 42 extends in the same direction as the first mounting post 33 and extends away from the main body 41. Thus, when the first locking member 40 slides in the extension direction, the second mounting post 42 can at least partially extend outside the mounting space and be inserted into the housing 10. Alternatively, when the first locking member 40 slides in the retraction direction, the second mounting post 42 can at least partially move into the mounting space to separate and unlock from the housing 10.

[0079] Optionally, both the first mounting post 33 and the second mounting post 42 are cylindrical. This reduces the frictional force when the first mounting post 33 and the second mounting post 42 slide relative to the housing 10. When the second locking member is a fixed shaft, the fixed shaft is cylindrical.

[0080] Alternatively, the cross-section of the first mounting post 33 and the second mounting post 42 may be triangular, quadrilateral, or polygonal, etc.

[0081] Alternatively, when the second locking element is a fixed shaft, the cross-section of the fixed shaft can be triangular, quadrilateral, or polygonal, etc.

[0082] In an optional embodiment of the above-mentioned purification device, combined with Figure 3 , Figure 4 As shown, the first peripheral portion 22 is provided with a first through hole 221, and the second peripheral portion 32 is provided with a second through hole 321 that mates with the first through hole 221. The first through hole 221 and the second through hole 321 together form an outlet hole through which the second mounting post 42 passes.

[0083] In this way, the extension of the second mounting post 42 can be guaranteed, and the stability of its movement can also be guaranteed, ensuring that it will not easily shift or loosen due to external forces during use. In addition, the through hole design can effectively reduce the friction between the second mounting post 42 and the first peripheral portion 22 and / or the second peripheral portion 32, thereby improving the smoothness of the sliding of the first locking member 40.

[0084] Specifically, the shape of the through hole matches the shape of the second mounting post 42.

[0085] When the second mounting post 42 has a cylindrical body, the through hole is also cylindrical. In this case, the friction between the two is small, making operation easier.

[0086] When the cross-section of the second mounting post 42 is a triangle, quadrilateral, or polygon, the cross-section of the through hole is also a triangle, quadrilateral, or polygon.

[0087] Alternatively, a first through hole 221 may be provided only on the first peripheral portion 22, that is, the first through hole 221 is a through hole.

[0088] Alternatively, a second through hole 321 can be provided only on the second peripheral portion 32, that is, the second through hole 321 serves as a through hole. This allows for support of the second cover 30, and thus, support of the entire purification device.

[0089] In an optional embodiment of the above-described purification device, the purification device further includes a guide assembly, which includes a guide rail 61 and a guide post 62. The guide rail 61 extends through the main body 41 and extends along the length of the first cover 20. The guide post 62 is disposed on the outer side of the first side plate 21 and inserted into the guide rail 61.

[0090] When the first locking member 40 extends or retracts, the guide rail 61 moves relative to the guide post 62 along the length of the first cover 20.

[0091] By configuring the guide assembly, the sliding process of the first locking member 40 can be further optimized. When the first locking member 40 extends or retracts, the guide rail 61 moves relative to the guide post 62, thereby achieving a precise guiding function. The cooperation between the two not only improves the ease of operation but also avoids installation failures caused by sliding deviations, improving the accuracy of installation and disassembly.

[0092] Since the guide rail 61 extends along the length of the first cover 20, it can ensure that the first locking member 40 moves along the length of the first cover 20, i.e. the length of the first side plate 21, by mutually restricting and cooperating with the guide post 62 when the first locking member 40 moves, thus avoiding the problem of displacement or misalignment of the first locking member 40 during the movement.

[0093] Optionally, the guide components are provided in two sets.

[0094] Alternatively, only one set of guide components can be set; or more than two sets of guide components can be set.

[0095] In an optional embodiment of the above-mentioned purification device, the end of the guide post 62 away from the second side plate 31 is provided with a protrusion 621. The protrusion 621 extends toward the first mounting post 33 or away from the first mounting post 33. The protrusion 621 is configured to clamp the main body 41 together with the first side plate 21.

[0096] In other words, the main body 41 is sandwiched between the protrusion 621 and the first side plate 21, thereby preventing the main body 41 from disengaging from the first side plate 21 and ensuring the stability of the first locking member 40 on the first side plate 21.

[0097] By providing a protrusion 621 at the end of the guide post 62 away from the first side plate, the reliability of the structure can be further enhanced, and the main body 41 can be effectively prevented from detaching from the first side plate 21 during sliding.

[0098] Alternatively, the protrusion 621 may also have portions extending in other directions, as long as it is possible to position the main body 41 between the protrusion 621 and the first side plate 21.

[0099] Optionally, the guide post 62 is integrally formed with the first side plate 21.

[0100] Alternatively, the guide post 62 is screwed to the first side plate 21, or connected in other ways.

[0101] In an optional embodiment of the above-described purification device, the guide assembly further includes a stop plate 63. The stop plate 63 is disposed on the outer side of the second side plate 31 and is spaced apart from the guide post 62.

[0102] The stop plate 63 is configured to abut against the corresponding main body 41 when the first locking member 40 slides in the retraction direction to achieve a stop engagement.

[0103] Optionally, the first locking member 40 slides along the extension direction and is inserted into the housing 10. The extension length of the second mounting post 42 extending out of the purification device is less than the preset distance between the side of the main body 41 near the stop plate 63 and the stop plate 63 at this time; and the sum of the extension length and the thickness of the first peripheral portion 22 and / or the second peripheral portion 32 is greater than or equal to the aforementioned preset distance. In this way, the second mounting post 42 can be prevented from falling off the first peripheral portion 22 and / or the second peripheral portion 32, reducing the difficulty of installation.

[0104] By setting the stop plate 63, when the first locking member 40 slides in the retraction direction, it can abut against the corresponding main body part 41 to achieve a stop engagement, thereby providing a clear displacement limit when the first locking member 40 is unlocked, avoiding excessive sliding and causing the second mounting post 42 to detach from the second peripheral part 32 and / or the first peripheral part 22, and avoiding damage to the structure.

[0105] Optionally, the stop plate 63 is integrally formed with the first side plate 21.

[0106] Alternatively, the stop plate 63 can be fixed by production personnel as needed. Fixing methods include, but are not limited to, welding, gluing, and screw connections.

[0107] In an optional embodiment of the purification device described above, the purification device further includes a limiting component, which includes a limiting post 71 and a limiting groove 72.

[0108] Two limiting posts 71 are disposed on the outer side of the first side plate 21, and are respectively located on both sides of the main body 41 in the width direction. Two sets of limiting grooves 72 are respectively disposed on both sides of the main body 41 in the width direction and recessed towards each other. Each set of limiting grooves 72 includes at least a first groove 721 and a second groove 722 that are smoothly connected.

[0109] When the first locking member 40 extends or retracts in the direction of extension, the limiting groove 72 moves relative to the corresponding limiting post 71 so that the first groove 721 or the second groove 722 engages with the limiting post 71.

[0110] When the first locking member 40 extends or retracts, the limiting groove 72 moves relative to the corresponding limiting post 71, causing the first groove 721 or the second groove 722 to engage with the limiting post 71. This not only ensures the stability of the first locking member 40 in the locked or unlocked position, but also simplifies the user's operation and improves the overall user experience.

[0111] The cooperation between the limiting post 71 and the limiting groove 72 can prevent the main body 41 from swaying in its own width direction.

[0112] Optionally, the first groove 721 and the second groove 722 are configured as arc-shaped grooves.

[0113] Optionally, the limiting post 71 is integrally formed with the first side plate 21.

[0114] In a second aspect, this application provides an indoor air conditioning unit, comprising: a housing 10, an air inlet 11 at the top, and at least two mounting plates 12 fixedly connected to the housing 10 at intervals along the length of the air inlet 11; and a purification device as described above, wherein the purification device is disposed between the two mounting plates 12 and is inserted into the mounting plates 12.

[0115] The purification device extends along the length of the air inlet 11 and its upper end is located at any position in the width direction of the air inlet 11. The purification device is arranged obliquely from top to bottom toward the front panel 13 of the housing 10 and encloses a flow space 101 that communicates with at least part of the air inlet 11 between itself and part of the front panel 13.

[0116] Specifically, a flow space 101 is enclosed between the purification device and the front panel 13, and a heat exchange space 102 is formed between the purification device and the back panel of the casing 10. The indoor heat exchanger is installed in the heat exchange space 102.

[0117] The purification device extends along the length of the air inlet 11, that is, the length of the first side plate 21 and the second side plate 31 is consistent with the length of the air inlet 11.

[0118] Thus, at least part of the air entering the casing 10 through the air inlet 11 flows directly into the heat exchange space, while the other part flows into the flow space. The air flowing into the flow space flows through the air inlet 210 and the air outlet 310 through the purification component 50 to decompose formaldehyde and convert ozone in the air, thereby improving air quality.

[0119] Alternatively, the purification device can be arranged to completely correspond to the air inlet 11 so that all the air flowing into the air inlet 11 passes through the purification device.

[0120] Alternatively, the purification device may be configured to include a straight section and an inclined section parallel to the air inlet 11, so that all the air flowing into the air inlet 11 passes through the purification device and can make full use of the space inside the housing 10, thereby improving space utilization.

[0121] Optionally, two mounting plates 12 are provided only along the length of the air inlet 11. The two mounting plates 12 are respectively inserted into the two sides of the purification device.

[0122] Alternatively, three mounting plates 12 are evenly spaced along the length of the air inlet 11, and a purification device is placed between two adjacent mounting plates 12. This reduces the length of the purification device, improves structural safety, and avoids bending problems during long-term use. In this design, the mounting plate 12 in the middle position is shared by two purification devices.

[0123] Alternatively, multiple mounting plates 12 can be provided along the length of the air inlet 11. The distance between adjacent mounting plates 12 can be equal or unequal, and the distance between adjacent mounting plates 12 should match the length of the corresponding air purification device.

[0124] Optionally, a fixing hole 121 is provided on the side of the mounting plate 12 near the air inlet 11, and the fixing hole 121 is configured to match the first mounting post 33. That is, the first mounting post 33 is inserted into the fixing hole 121.

[0125] Since the mounting plate 12 is usually not flexible, in order to facilitate the installation of the first mounting post 33, a mounting guide groove 122 is provided on the mounting plate 12. One end of the mounting guide groove 122 is connected to the fixing hole 121, and the other end extends toward the front panel 13 and is open.

[0126] Thus, when installing the purification device, the first mounting post 33 is first placed into the mounting guide groove 122 through the opening, and the purification device is pushed to move towards the fixing hole 121 so that the first mounting post 33 is inserted into the fixing hole 121.

[0127] Optionally, the bottom surface of the fixing hole 121 is lower than the bottom surface of the mounting guide groove 122. It should be noted that the bottom surface of both the fixing hole 121 and the bottom surface of the mounting guide groove 122 refer to the side facing away from the air inlet 11.

[0128] Optionally, the mounting plate 12 has a mounting hole 123. The mounting hole 123 is configured to mate with the second mounting post 42 / second locking member of the first locking member 40.

[0129] Optionally, the portion of the mounting hole 123 near the air inlet 11 has a cut. The cut has a first side and a second side. The distance between the first side and the second side is less than the diameter of the second mounting post 42. And when the second locking member is a fixed shaft, the distance between the first side and the second side is less than the diameter of the fixed shaft.

[0130] Optionally, the mounting plate 12 is provided with integrally formed ribs protruding from its side. The cooperation between multiple ribs forms fixing holes 121, mounting guide grooves 122, and mounting holes 123. In this way, the mounting plate 12 can be provided with corresponding fixing holes 121, mounting guide grooves 122, and mounting holes 123 on both sides, which facilitates the installation of multiple purification devices.

[0131] In addition, the arrangement of the integrally molded ribs also helps to improve the structural stability and strength of the mounting plate.

[0132] Optionally, the mounting plate 12 is integrally formed with the housing 10. This reduces costs while increasing structural strength.

[0133] Optionally, the mounting plate 12 is connected to the housing 10 by means of screws or other methods.

[0134] With the above technical solution, the upper end of the purification device is located at any position in the width direction of the air inlet 11, and is inclined downwards towards the front panel 13 of the housing 10. This ensures that the purification device corresponds to at least a portion of the air inlet 11. The first and second covers 20 and 30, after being connected, can be installed on the housing 10 using the first locking member 40 and the second locking member. Since the air inlet 210 faces the air inlet 11, the air inlet 210 and the air outlet 310, respectively provided on the first and second covers 20 and 30, allow some of the air entering the housing 10 to pass through the purification device, thereby decomposing formaldehyde in the air and converting ozone in the air into oxygen and water, reducing the content of harmful gases in the air, and improving air cleanliness and air quality.

However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.

For example, any of the claimed embodiments in the claims of this application can be used in any combination.
