Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, specifically to an oxygen generating device, an outdoor air conditioning unit, and an air conditioning equipment. Background Technology

[0002] Currently, air-conditioning systems that generate oxygen require an oxygen-generating structure and a filter structure to work in conjunction with it. The filter structure primarily filters the gas flowing into the oxygen-generating structure to reduce impurities and extend its lifespan. Air-conditioning systems can be broadly categorized into four types based on the specific location of the filter and oxygen-generating structures: indoor oxygen generation with filtration (both located indoors), indoor oxygen generation with outdoor filtration (located outdoors), outdoor oxygen generation with indoor filtration (located indoors), and outdoor oxygen generation with filtration (both located outdoors). Among these, because the oxygen-generating structure generates significant noise during operation, most systems on the market prefer to place it outdoors to improve the user experience, while the placement of the filter structure varies.

[0003] In existing technologies, regardless of whether the filter structure is placed indoors or outdoors, users need to clean the surface of the filter screen to prevent dust and other impurities from clogging the filter screen, which would reduce the airflow and velocity, and thus ensure that the oxygen production function of the air conditioner can be realized normally.

[0004] However, since the oxygen generator and filter structure are both located inside the air conditioner, the above cleaning process is extremely inconvenient for ordinary users (it requires partial disassembly of the air-generating air conditioner). Furthermore, once the filter structure becomes clogged, its lifespan will be greatly shortened and the replacement cost will increase, seriously affecting the user experience. Utility Model Content

[0012] Furthermore, the filter assembly also includes a second filter structure disposed within the mounting cavity, the second filter structure being located between the first filter structure and the connecting portion, for further filtering the gas filtered by the first filter structure.

[0013] Furthermore, the housing portion also has an insertion port communicating with the mounting cavity, through which the second filter structure is detachably inserted into the mounting cavity; wherein, the mounting structure also includes a sealing member, which is disposed at the insertion port for sealing the insertion port.

[0014] According to another aspect of the present invention, an outdoor unit for an air conditioner is provided, comprising: a housing assembly including a main housing and a mounting component, the mounting component being disposed in the inner cavity of the main housing to divide the inner cavity of the main housing into a heat exchange cavity and a mounting cavity; an oxygen generating device disposed in the mounting cavity; and a heat exchange device and a fan device disposed in the heat exchange cavity; wherein the oxygen generating device is the aforementioned oxygen generating device.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0023] To address the problems of short service life and inconvenient cleaning of filter consumables in the oxygen generation components of existing air conditioners, this application provides an oxygen generation device, an outdoor air conditioning unit, and an air conditioning equipment.

[0024] like Figures 1 to 7 As shown, the oxygen generating device includes an oxygen generating structure 10 and a filter assembly. The oxygen generating structure 10 is used to generate oxygen and has an air inlet. The filter assembly includes a mounting structure 20, a first filter structure 30, and a cleaning structure 40. The mounting structure 20 has an air inlet 21 and a connecting part 22 that are interconnected, with the connecting part 22 communicating with the air inlet. The first filter structure 30 is disposed at the air inlet 21 to filter the gas flowing through the air inlet 21. At least a portion of the outer surface of the cleaning structure 40 is in contact with the first filter structure 30. The cleaning structure 40 and the first filter structure 30 are movably disposed relative to each other, and during the relative movement between the cleaning structure 40 and the first filter structure 30, the cleaning structure 40 cleans the first filter structure 30.

[0025] Applying the technical solution of this embodiment, the oxygen generating structure 10 of the oxygen generating device is used to generate oxygen. The oxygen generating structure 10 has an air inlet, and the filter assembly includes an installation structure 20, a first filter structure 30, and a cleaning structure 40. The installation structure 20 has an air inlet 21 and a connecting part 22 that are interconnected. The connecting part 22 is connected to the air inlet. The first filter structure 30 is disposed at the air inlet 21 to filter the gas flowing through the air inlet 21. At least a portion of the outer surface of the cleaning structure 40 is in contact with the first filter structure 30. The cleaning structure 40 and the first filter structure 30 are movably disposed relative to each other. During the relative movement between the cleaning structure 40 and the first filter structure 30, the cleaning structure 40 cleans the first filter structure 30. Thus, in this embodiment, the oxygen generator, while providing a first filter structure 30 to filter impurities in the airflow flowing into the oxygen generator structure 10, also additionally provides a cleaning structure 40. This cleaning structure 40, through the relative movement between itself and the first filter structure 30, wipes and removes impurities from the surface of the first filter structure 30, thereby giving the oxygen generator a self-cleaning function. This design not only avoids the need for users to manually disassemble the air conditioner and perform cleaning, reducing the difficulty of cleaning, but also facilitates frequent, periodic cleaning by the user, reducing the probability of clogging the first filter structure 30 and extending its service life. This solves the problem of short service life and inconvenient cleaning of the filter consumables in the oxygen generator components of existing air conditioners, improving the user experience.

[0026] In this embodiment, the oxygen generating device further includes a medium supply structure 70, and the connecting portion 22 of the mounting structure 20 is connected to the air inlet through the medium supply structure 70.

[0027] In this embodiment, the medium supply structure 70 is an air compressor. That is, after the air filtered by the filter assembly flows into the air compressor, it can be converted into high-pressure gas under the action of the air compressor and further supplied to the oxygen generating structure 10 to ensure that the oxygen generating function of the oxygen generating structure 10 can be realized.

[0028] like Figure 1 and Figure 8 As shown, the oxygen generating structure 10 is a molecular sieve oxygen generating structure. Specifically, it includes a solenoid valve 11, multiple molecular sieve structures 12 (two in this embodiment), a one-way valve 13, a gas storage structure 14, and a silencer 15. The high-pressure gas supplied by the medium structure 70 is simultaneously introduced into the two molecular sieve structures 12 through the solenoid valve 11. After the gas is screened by the molecular sieve structures 12, the enriched oxygen is introduced into the gas storage structure 14. A one-way valve 13 is provided between the molecular sieve structures 12 and the gas storage structure 14 to prevent the oxygen-enriched gas from flowing back. The remaining mixed gas (mainly nitrogen) after being screened by the molecular sieve structures 12 flows back to the solenoid valve 11 and is further transported to the silencer 15. After being silenced by the silencer 15, it is discharged into the atmosphere.

[0029] It should be noted that the specific structure of the molecular sieve oxygen generator is relatively conventional and will not be described in detail here.

[0030] In this embodiment, the cleaning structure 40 is a cleaning roller brush, the outer peripheral surface of which forms a cleaning surface that fits into the first filter structure 30.

[0031] like Figures 2 to 7 As shown, the first filter structure 30 is movably disposed, and the filter assembly also includes a drive structure 50, which is drivenly connected to the first filter structure 30 to drive the first filter structure 30 to move. During the movement, the first filter structure 30 covers the air intake 21. In this way, the above arrangement, on the one hand, realizes the automated movement of the first filter structure 30 through the drive structure 50, improving the automation level of the oxygen generator; on the other hand, it ensures that the first filter structure 30 has high filtration reliability.

[0032] In other embodiments not shown in the accompanying drawings, the cleaning structure is movably configured, i.e., the first filter structure is fixed, and the driving structure is driven to be connected to the cleaning structure to drive the cleaning structure to reciprocate, thereby cleaning the surface of the first filter structure.

[0033] like Figures 2 to 7As shown, the mounting structure 20 also has a mounting cavity 23, through which the air intake 21 communicates with the connecting portion 22. The first filter structure 30 is arranged in a ring shape. The first filter structure 30 is rotatably disposed within the mounting cavity 23. At least a portion of the drive structure 50 is located within the mounting cavity 23 and is driven to rotate the first filter structure 30. This ring-shaped arrangement of the first filter structure 30 provides a larger filtration area. During rotation, the uncontaminated portion of the first filter structure 30 can move to cover the air intake 21 for filtration. This arrangement further extends the service life of the first filter structure 30, thereby reducing the frequency of replacement and improving the user experience.

[0034] like Figures 2 to 7 As shown, the mounting structure 20 includes a housing portion 24 and a limiting portion 25. The housing portion 24 has an air intake portion 21, a mounting cavity 23, and a communicating portion 22. The limiting portion 25 is disposed in the mounting cavity 23, and a limiting space is formed between the limiting portion 25 and the cavity wall of the mounting cavity 23. The first filter structure 30 is located within the limiting space. The limiting portion 25 is used to limit and stop the first filter structure 30 during its rotation. In this way, the limiting portion 25 can limit and stop the first filter structure 30 during its rotation, thereby improving the rotational stability of the first filter structure 30, preventing the first filter structure 30 from shifting and causing a large gap between it and the air intake portion 21, and thus improving the filtration reliability of the first filter structure 30.

[0035] like Figures 2 to 7 As shown, the first filter structure 30 includes a flexible filter body 31 and a flexible support strip 32. The flexible filter body 31 is annularly arranged and is used to filter gas. The flexible support strip 32 is disposed on the flexible filter body 31, and is annular and concentrically arranged with the flexible filter body 31. A rack portion 321 is provided on the flexible support strip 32. The drive structure 50 includes a drive member 51 and a gear member 52. The gear member 52 is rotatably disposed in the mounting cavity 23 and is drivenly connected to the drive member 51. The gear member 52 meshes with the rack portion 321. When the drive member 51 drives the gear member 52 to rotate, the gear member 52 drives the flexible filter body 31 to rotate through the rack portion 321, causing deformation of the flexible filter body 31 and the flexible support strip 32. In this way, the flexible support bar 32 supports the flexible filter body 31 to maintain its basic annular shape, and the above-mentioned flexible arrangement of both allows the first filter structure 30 to adapt to different shapes during rotation, thereby adapting to different structures of the housing part 24. At the same time, the meshing of the gear part 52 and the rack part 321 enables the stable rotation of the flexible support bar 32 (first filter structure 30).

[0036] In this embodiment, the flexible filter body 31 is a filter screen.

[0037] In this embodiment, the housing part 24 is a rectangular housing, the first filter structure 30 is a matching rectangular ring, and the above-mentioned arrangement of the flexible filter body 31 and the flexible support bar 32 enables the first filter structure 30 to maintain its rectangular shape during rotation.

[0038] It should be noted that if the first filter structure 30 is set to an annular shape (the housing part 24 is set accordingly), the first filter structure 30 may also be provided with a rigid structure.

[0039] In this embodiment, the driving component 51 is a servo motor.

[0040] Optionally, the filter assembly also includes a detection element and a control module. The detection element can be set in the mounting cavity 23 to detect the air intake in the mounting cavity 23. If the air intake in the mounting cavity 23 is less than the threshold, it is determined that the flexible filter body 31 is blocked. The control module is connected to both the detection element and the control module to control the drive element 51 to start according to the detection result of the detection element, thereby realizing the automated cleaning of the first filter structure 30.

[0041] Optionally, the detection element can also be a counting element, which is used to measure the running time of the oxygen generating structure 10 or the total number of starts of the oxygen generating device. When the count value of the counting element reaches the threshold, the control module controls the drive element 51 to start, thereby realizing the automated cleaning of the first filter structure 30.

[0042] Alternatively, a detection component may not be provided. Instead, the control module is connected to the main control board of the air conditioner. When the oxygen generation function of the air conditioner is turned on, the control module controls the drive component 51 to start, so as to realize the self-cleaning function of the first filter structure 30.

[0043] like Figures 2 to 7As shown, the limiting part 25 is rod-shaped, and there are multiple limiting parts 25, which are spaced apart around the rotation axis of the first filter structure 30. There are at least two flexible support bars 32, which are spaced apart along the circumferential width direction of the flexible filter body 31. At least one limiting part 25 has a protrusion 26 on its outer peripheral surface, which limits and stops the flexible support bar 32 along the circumferential width direction of the flexible filter body 31. There are at least two protrusions 26, which are arranged in a one-to-one correspondence with at least two flexible support bars 32. In this way, the above arrangement not only increases the limiting area of ​​the first filter structure 30 by the multiple limiting parts 25, thereby further improving the rotational stability of the first filter structure 30, but also adapts to the shape of the first filter structure 30, ensuring that the first filter structure 30 maintains its basic shape during rotation. Meanwhile, the protrusion 26 can unfold the first filter structure 30 to prevent the two flexible support bars 32 of the flexible first filter structure 30 from moving toward each other and stacking on the flexible filter body 31, thus further improving the filtration reliability of the first filter structure 30.

[0044] In this embodiment, the housing part 24 includes a housing body 242 and a cover 243 that are interlocked. The housing body 242 is provided with an insertion protrusion 2421, and the cover 243 includes a cover plate 2431 and a surrounding plate 2432 provided on the cover plate 2431. The insertion protrusion 2421 is inserted into the inner side of the surrounding plate 2432 so that the two surround each other to form a mounting cavity 23.

[0045] Specifically, the insertion protrusion 2421 is a plate-shaped structure, with its plate surface and the surrounding plate 2432 arranged opposite to each other, and the limiting part 25 is located between the insertion protrusion 2421 and the surrounding plate 2432.

[0046] Specifically, in this embodiment, the cover plate 2431 is a rectangular plate, and there are only two surrounding plates 2432. That is, the part without surrounding plates 2432 forms a corresponding clearance opening. Similarly, the plate-shaped insertion protrusion 2421 is provided in accordance with the structure of the surrounding plate 2432 to form an air intake 21 (air intake hole).

[0047] It should be noted that the arrangement of the air intake 21 is not limited to this. For example, a single enclosure 2432 can be provided to form an air intake 21 with a larger air intake area on three sides of the rectangular housing 24. Alternatively, three enclosures 2432 can be provided to form an air intake 21 with a smaller air intake area on one side of the rectangular housing 24.

[0048] In this embodiment, there are two flexible support bars 32, and the flexible filter body 31 is located between the two flexible support bars 32.

[0049] In this embodiment, there are two protrusions 26, and the two protrusions 26 are arranged in a one-to-one correspondence with the two flexible support bars 32.

[0050] In this embodiment, the protrusion 26 is a wedge-shaped block structure, at least part of which has an inclined surface, and the inclined surface is disposed opposite to the flexible support strip 32. In this way, the above-mentioned arrangement, by limiting and stopping the flexible support strip 32 through the inclined surface and the flexible support strip 32, can prevent one flexible support strip 32 from moving toward another flexible support strip 32 and causing the flexible filter body 31 to stack, while also providing a certain amount of room for movement to prevent the first filter structure 30 from getting stuck during rotation, further improving the rotational stability of the first filter structure 30.

[0051] like Figures 2 to 8 As shown, the filter assembly also includes a second filter structure 60, which is disposed within the mounting cavity 23 and located between the first filter structure 30 and the connecting portion 22. The second filter structure 60 is used to further filter the gas that has been filtered by the first filter structure 30. Thus, the above arrangement achieves secondary filtration of the gas through the second filter structure 60, further reducing the impurity content of the gas entering the supply medium structure 70 and the oxygen generation structure 10, and helping to further extend the service life of the supply medium structure 70 and the oxygen generation structure 10.

[0052] In this embodiment, the second filter structure 60 is a HEAP mesh, which has a smaller impurity filtration radius, and works in conjunction with the first filter structure 30 to form a graded filtration system.

[0053] like Figures 2 to 7 As shown, the housing 24 also has an insertion port 241 communicating with the mounting cavity 23, through which the second filter structure 60 is detachably inserted into the mounting cavity 23. The mounting structure 20 also includes a sealing member 27, which is disposed at the insertion port 241 to seal it. This arrangement allows for quick replacement of the second filter structure 60, further reducing the difficulty of replacement for the user. Furthermore, by sealing the insertion port 241 with the sealing member 27, it helps maintain a constant gas pressure within the mounting cavity 23 during normal operation of the oxygen generator, ensuring that the supply medium structure 70 can input gas at a stable pressure.

[0054] In this embodiment, a mounting recess is provided on the outer peripheral surface of the housing portion 24, and an insertion port 241 is provided on the bottom wall of the mounting recess. The sealing member 27 is plate-shaped and is embedded in the mounting recess by fasteners or a snap-fit ​​structure. In this way, the above-mentioned arrangement helps to improve the sealing reliability of the sealing member 27 at the insertion port 241.

[0055] like Figure 9 and Figure 10As shown, this embodiment also provides an outdoor air conditioning unit, including a housing assembly 200, an oxygen generator, a heat exchanger, and a fan assembly 300. The housing assembly 200 includes a main housing 210 and a mounting component 220. The mounting component 220 is disposed in the inner cavity of the main housing 210 to divide the inner cavity of the main housing 210 into a heat exchange chamber 211 and a mounting chamber 212. The oxygen generator is disposed in the mounting chamber 212. The heat exchanger and fan assembly 300 are disposed in the heat exchange chamber 211. The oxygen generator is the one described above. Thus, in this embodiment, the entire oxygen generator (oxygen generator structure 10, filter assembly, and medium supply structure 70) is disposed on the outdoor air conditioning unit. This arrangement helps to shorten the pipe routing distance between the oxygen generator structure 10, the filter assembly, and the medium supply structure 70, making the piping layout between the indoor air conditioning units simpler, reducing processing costs, and simplifying design. Meanwhile, the mounting component 220 can act as a separator to prevent the heat exchange device and fan device 300 from interfering with each other's operation with the oxygen generation device, which helps to improve the overall operational stability of the outdoor unit of the air conditioner.

[0056] like Figure 9 and Figure 10 As shown, the mounting cavity 212 is located above the heat exchange cavity 211. The mounting member 220 has a communication port 221, through which the mounting cavity 212 communicates with the heat exchange cavity 211. There are multiple communication ports 221, spaced apart along the length and / or width direction of the mounting member 220. At least one communication port 221 is located below the first filter structure 30 of the oxygen generator, allowing impurities cleaned by the first filter structure 30 to fall into the heat exchange cavity 211 through this communication port 221. Thus, impurities cleaned by the cleaning structure 40 of the oxygen generator can spontaneously fall into the heat exchange cavity 211 through the aforementioned communication port 221 under their own gravity, and are then directly blown out to the outside of the air conditioner outdoor unit by the airflow from the air device within the heat exchange cavity 211, further achieving a self-cleaning effect.

[0057] This embodiment also provides an air conditioning device (not shown), which includes an outdoor unit and an indoor unit, with the outdoor unit connected to the indoor unit. The outdoor unit is the one described above.

[0058] Specifically, the oxygen-generating device in the outdoor unit of the air conditioner produces oxygen-rich gas from the air and sends it to the indoor unit of the air conditioner through corresponding pipelines, and then further into the room, in order to increase the indoor oxygen concentration and purify the indoor air.

[0059] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects: The oxygen generating structure of the oxygen generating device is used to produce oxygen. The oxygen generating structure has an air inlet, and the filter assembly includes an installation structure, a first filter structure, and a cleaning structure. The installation structure has an air inlet and a connecting part that are interconnected. The connecting part is connected to the air inlet. The first filter structure is disposed at the air inlet to filter the gas flowing through it. At least a portion of the outer surface of the cleaning structure is in contact with the first filter structure. The cleaning structure and the first filter structure are movable relative to each other, and during this relative movement, the cleaning structure cleans the first filter structure. Thus, the oxygen generator in this application, while setting a first filter structure to filter impurities in the airflow flowing into the oxygen generator structure, also additionally sets a cleaning structure. Through the relative movement between the cleaning structure and the first filter structure, impurities on the surface of the first filter structure are wiped and removed, thereby giving the oxygen generator a self-cleaning function. The above-mentioned setting not only avoids the step of manually disassembling the air conditioner and performing corresponding cleaning, reducing the difficulty of cleaning for users, but also makes it easier for users to operate the cleaning structure for high-frequency periodic cleaning, thereby reducing the probability of clogging of the first filter structure and extending the service life of the first filter structure. This solves the problem of short service life and inconvenient cleaning of the filter consumables of the oxygen generator component in the prior art, and improves the user experience.
