Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and more specifically, to a fresh air device and an air conditioner having the same. Background Technology

[0002] Air conditioning systems play a vital role in modern life and work, not only regulating indoor temperature to adapt to seasonal changes but also improving indoor air quality by introducing fresh air. However, as people's demands for health and comfort increase, traditional air conditioning systems are proving inadequate in addressing declining indoor oxygen levels and poor air quality. Therefore, existing technologies incorporate oxygen-generating equipment within air conditioners to produce oxygen from outdoor air before introducing it into the room, thereby increasing indoor oxygen levels.

[0003] Traditional oxygen generators typically draw air from outdoors, lacking flexibility and unable to adjust to actual indoor needs or outdoor air quality. In some cases, poor outdoor air quality can lead to frequent filter replacements, increasing maintenance costs. Furthermore, drawing in cooler outdoor air directly affects indoor temperature, especially in winter, where low temperatures can cause condensation on the oxygen generator ducts, leading to corrosion over time and shortening the equipment's lifespan.

[0011] Furthermore, the fresh air device also includes: a duct assembly, which includes a first duct and a second duct. The two ends of the first duct are connected to the outdoor environment and a first channel, respectively. Outdoor fresh air is introduced into the first channel through the first duct. The two ends of the second duct are connected to an oxygen generating component and a second channel, respectively. Fresh air in the second channel is transported to the oxygen generating component for oxygen generation through the second duct.

[0012] Furthermore, the first channel includes: a first flow section and a second flow section that are interconnected, an outdoor air inlet located between the first flow section and the second flow section, and an indoor air inlet, a first air outlet and a second air outlet respectively connected to the second flow section; wherein, a first pipe fitting is connected to the first flow section, a second pipe fitting is inserted into the first pipe fitting, and the air inlet end of the second pipe fitting passes through the first pipe fitting and then through the first flow section to connect with the second channel.

In addition, the oxygen-generating components and the fresh air system share the same air duct, so the fresh air system not only has the function of providing fresh air to the room but also provides an air source for the oxygen-generating components, reducing the wear and tear on the functional components inside the oxygen-generating components and extending the service life of each component.

[0034] 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.

[0035] As mentioned in the background section, existing air conditioners incorporate oxygen generators to improve the indoor environment and increase the oxygen content in the indoor air. Currently, these oxygen generators draw their air source from outdoor air. When outdoor air quality is poor and oxygen generation is required simultaneously, it increases wear and tear on internal components such as filters. Furthermore, when outdoor temperatures are low, directly using outdoor air for oxygen generation not only lowers the indoor temperature but also causes condensation in the oxygen generator ducts, leading to corrosion over time and impacting the equipment's lifespan. Therefore, to address these technical problems, this application provides a fresh air system housed within the indoor unit 100. The fresh air system includes a fresh air duct 310, which has an outdoor air inlet 311, an indoor air inlet 312, a first air outlet 313, and a second air outlet 314. The outdoor air inlet 311 connects to the outdoor environment to introduce fresh outdoor air into the fresh air duct 310; the indoor air inlet 312 connects to the indoor environment to introduce indoor air into the fresh air duct 310; and the first air outlet 314... 3 is used to connect with the indoor environment. The second air outlet 314 is connected to the oxygen generating component 210 so that part of the fresh air in the fresh air duct 310 is discharged into the room through the first air outlet 313, and the other part is discharged into the oxygen generating component 210 through the second air outlet 314 for oxygen generation. The outdoor air inlet 311 and the indoor air inlet 312 can be selectively opened or closed so that outdoor fresh air and indoor air are simultaneously introduced into the fresh air duct 310, or one of the outdoor fresh air or indoor air is introduced into the fresh air duct 310. This configuration allows the fresh air unit to selectively draw air from either the outside or the inside, depending on the outdoor air quality and temperature, to supply the oxygen-generating component 210 with the necessary air source for oxygen production. When the outdoor temperature is too low, the indoor air circulation mode avoids energy loss caused by introducing cold air, ensuring that the produced oxygen does not affect the indoor temperature. When the outdoor air quality is poor, closing the outdoor air inlet 311 and using the indoor air inlet 312 for internal circulation also reduces the degree of contamination of the filter inside the fresh air unit. Furthermore, the oxygen-generating component 210 and the fresh air unit share the same air duct, enabling the fresh air unit to not only provide fresh air to the room but also supply air to the oxygen-generating component 210, reducing wear and tear on the functional components inside the oxygen-generating component 210 and extending the service life of each component.

[0036] Please refer to Figures 1 to 7This application provides a fresh air device, at least partially installed within an indoor unit 100. The fresh air device includes: a fresh air duct 310, installed within the indoor unit 100, the fresh air duct 310 having an outdoor air inlet 311, an indoor air inlet 312, a first air outlet 313, and a second air outlet 314; the outdoor air inlet 311 is used to communicate with the outdoor environment to introduce outdoor fresh air into the fresh air duct 310; the indoor air inlet 312 is used to communicate with the indoor environment to introduce indoor air into the fresh air duct 314; the first... The air outlet 313 is used to connect with the indoor environment, and the second air outlet 314 is connected with the oxygen generating component 210, so that part of the fresh air in the fresh air duct 310 is discharged into the room through the first air outlet 313, and the other part is discharged into the oxygen generating component 210 for oxygen generation through the second air outlet 314; wherein, the outdoor air inlet 311 and the indoor air inlet 312 can be selectively opened or closed, so that outdoor fresh air and indoor air are simultaneously introduced into the fresh air duct 310, or one of the outdoor fresh air or indoor air is introduced into the fresh air duct 310.

[0037] The fresh air device provided in this application includes a fresh air duct 310, which is installed inside an indoor unit 100. The fresh air duct 310 has an outdoor air inlet 311, an indoor air inlet 312, a first air outlet 313, and a second air outlet 314. The outdoor air inlet 311 is used to communicate with the outdoor environment to introduce outdoor fresh air into the fresh air duct 310. The indoor air inlet 312 is used to communicate with the indoor environment to introduce indoor air into the fresh air duct 310. The first air outlet 313 is used to communicate with the indoor environment. The environment is connected, and the second air outlet 314 is connected to the oxygen generating component 210, so that part of the fresh air in the fresh air duct 310 is discharged into the room through the first air outlet 313, and the other part is discharged into the oxygen generating component 210 through the second air outlet 314 for oxygen generation; wherein, the outdoor air inlet 311 and the indoor air inlet 312 can be selectively opened or closed, so that outdoor fresh air and indoor air are simultaneously introduced into the fresh air duct 310, or one of the outdoor fresh air or indoor air is introduced into the fresh air duct 310.

[0038] The outdoor air inlet 311 and indoor air inlet 312 of the fresh air duct 310 can be selectively opened or closed, enabling the air conditioning system to automatically or manually switch the air source according to the outdoor temperature and air quality, providing not only comfortable fresh air for the indoor environment, but also the best air source for the oxygen generation components.

[0039] In cold winters, closing the outdoor air inlet 311 and using the indoor air inlet 312 for air circulation and oxygen production can avoid introducing low-temperature outdoor air and reduce the additional burden on indoor heating needs. When outdoor air quality is poor (such as smog, industrial pollution, etc.), the system closes the outdoor air inlet 311 and uses indoor air as the basis for oxygen production and circulation, avoiding the introduction of outdoor pollutants and ensuring indoor air quality.

[0040] When the indoor oxygen content is low and rapid oxygen production is needed, the indoor air inlet 312 and the outdoor air inlet 311 can be opened simultaneously to increase the airflow in the fresh air duct 310, thereby increasing the air supply flow to the oxygen generating component 210 and causing the indoor oxygen content to rise rapidly.

[0041] By integrating with the indoor unit 100, the fresh air duct 310 and the oxygen generation component 210 share the same air duct, which not only reduces the indoor space occupied by the equipment, but also simplifies the system structure, reduces manufacturing costs, and improves the overall space utilization efficiency.

[0042] Specifically, such as Figure 1 and Figure 2 As shown, the fresh air device also includes a switching component 400, which is rotatably disposed between the outdoor air inlet 311 and the indoor air inlet 312, so that the outdoor air inlet 311 is opened and the indoor air inlet 312 is closed; or the indoor air inlet 312 is opened and the outdoor air inlet 311 is closed; or the outdoor air inlet 311 and the indoor air inlet 312 are opened simultaneously.

[0043] By rotating the switching component 400, the system can automatically or seamlessly switch to the optimal operating mode—outdoor fresh air mode, indoor circulation mode, or mixed mode—based on user settings, without frequent manual intervention. When the outdoor temperature is low, the switching component 400 closes the outdoor air inlet 311 and opens the indoor air inlet 312, reducing the additional heating requirement caused by introducing cold air. When the outdoor air quality is poor, the switching component 400 can respond quickly by closing the outdoor air inlet 311, ensuring indoor air circulation is unaffected by external pollution, providing users with a healthier and safer breathing environment.

[0044] When the indoor air quality is poor and the oxygen content is low, the outdoor air inlet 311 and the indoor air inlet 312 can be opened at the same time, and the switching component 400 can be rotated between the outdoor air inlet 311 and the indoor air inlet 312. When the outdoor air quality is good and the temperature is suitable, the indoor air inlet 312 can be closed and the outdoor air inlet 311 can be opened to provide fresh air to the room and provide an air source for the oxygen generating component 210.

[0045] In the specific implementation process, a first stop part 320 is provided in the fresh air duct 310, the first stop part 320 surrounds the indoor air inlet 312, and at least part of the switching component 400 is in contact with the first stop part 320 to block the indoor air inlet 312.

[0046] The switching component 400 fits snugly against the first stop 320, effectively blocking the indoor air inlet 312 and forming a good airflow seal. This ensures that indoor air will not accidentally mix into the fresh air channel when the outdoor fresh air mode is in operation. This snug fit design accelerates the switching process between different modes, enabling the switching component 400 to quickly open or close the indoor air inlet 312, thereby improving the system response speed and the overall efficiency of mode switching.

[0047] The fresh air duct 310 is also provided with a second stop 330, which forms an outdoor air inlet 311. At least a portion of the switching component 400 is in contact with the second stop 330 to block the outdoor air inlet.

[0048] The fitting mechanism between the second stop 330 and the switching component 400 ensures that outdoor air will not accidentally enter the fresh air duct in indoor circulation mode, thereby improving the accuracy of airflow management. In cold or extreme weather conditions, by blocking the outdoor air inlet 311 by the switching component 400, the introduction of cold or harsh air can be reduced, avoiding negative impacts on indoor temperature and additional heating or purification energy consumption.

[0049] The first stop portion 320 has a first stop end face 3201 that fits against the switching component 400, and the second stop portion 330 has a second stop end face 3301 that fits against the switching component 400. The plane containing the first stop end face 3201 and the plane containing the second stop end face 3301 form an angle, which is an acute angle. The switching component 400 is disposed between the first stop portion 320 and the second stop portion 330.

[0050] The acute angle design makes the switching component 400 have a shorter path and faster switching speed when rotating to switch the air inlet, making the overall structure more compact.

[0051] The fit between the first stop end face 3201 and the second stop end face 3301 and the switching component 400, combined with the layout of the acute angle, can effectively enhance the airflow isolation effect, ensure that when a certain air inlet is closed, the airflow can be completely blocked, improve the airtightness of the system in different modes, and prevent cross-contamination of air.

[0052] The first stop end face 3201 is provided with a first sealing element, and the second stop end face 3301 is provided with a second sealing element. The switching component 400 fits with the first sealing element to block and seal the indoor air inlet 312, and the switching component 400 fits with the second sealing element to block and seal the outdoor air inlet 311. This not only improves the sealing effect of the indoor air inlet 312 or the outdoor air inlet 311, but also reduces the noise of the switching component 400 during operation.

[0053] In the embodiments provided in this application, the fresh air duct 310 includes: a first duct 315 and a second duct 316 that are interconnected. The first duct 315 is connected to the outdoor air inlet 311, the indoor air inlet 312 and the first air outlet 313 respectively. The second duct 316 is connected to the second air outlet 314. After the outdoor fresh air or indoor air flows through the first duct 315, part of it is discharged into the room through the first air outlet 313, and the other part is discharged into the oxygen generating component 210 for oxygen generation after passing through the second duct 316 and the second air outlet 314.

[0054] The first channel 315 can simultaneously connect to the outdoor air inlet 311, the indoor air inlet 312, and the first air outlet 313. This allows air entering the first channel to be distributed as follows: some air is directly discharged into the room through the first air outlet 313, providing fresh air; the other part is transported to the oxygen generation unit 210 through the second channel 316 and the second air outlet 314 for oxygen separation and extraction. This design achieves independent and efficient air circulation and oxygen generation processes, improving the flexibility and efficiency of the air conditioning system in providing fresh air and oxygen.

[0055] like Figure 5 As shown, the fresh air device also includes a duct assembly 500, which includes a first duct 510 and a second duct 520. The two ends of the first duct 510 are connected to the outdoor environment and the first channel 315, respectively. Outdoor fresh air is introduced into the first channel 315 through the first duct 510. The two ends of the second duct 520 are connected to the oxygen generating assembly 210 and the second channel 316, respectively. Fresh air in the second channel 316 is transported to the oxygen generating assembly 210 for oxygen generation through the second duct 520.

[0056] The first fitting 510 and the second fitting 520 enable precise guidance between the outdoor fresh air and the oxygen generation components, ensuring that outdoor air can be directly and efficiently delivered to the oxygen generation system for processing. Through independent pipeline design, the air flow in the fresh air and oxygen generation processes does not undergo mixing, reducing the possibility of cross-contamination of air during transmission and ensuring the quality and purity of the oxygen-generated air.

[0057] The first fitting 510 is dedicated to the introduction of outdoor fresh air, avoiding unnecessary pretreatment energy consumption, while the second fitting 520 directly guides the fresh air to the oxygen generation component, reducing energy loss during air transmission and thus improving the overall system's energy efficiency.

[0058] In specific implementation, the first channel 315 includes: a first flow section 3150 and a second flow section 3151 that are interconnected; an outdoor air inlet 311 is located between the first flow section 3150 and the second flow section 3151; an indoor air inlet 312, a first air outlet 313, and a second air outlet 314 are respectively connected to the second flow section 3151; wherein, a first pipe fitting 510 is connected to the first flow section 3150; a second pipe fitting 520 is inserted into the first pipe fitting 510; the air inlet end of the second pipe fitting 520 passes through the first pipe fitting 510 and then through the first flow section 3150 to connect with the second channel 316.

[0059] The first fitting 510 connects to the first flow section 3150, ensuring that outdoor air can quickly and directly enter the first flow section, reducing airflow resistance and loss during transmission. Simultaneously, the second fitting 520 passes through the first fitting 510, further reducing the air transmission path, accelerating airflow speed, and lowering the complexity of the duct layout. Integrating the second fitting 520 with the first fitting 510 improves the overall compactness of the fresh air system and solves the problem of needing multiple pipe wrappings and additional drilling into the wall when running both fresh air and oxygen generation pipes simultaneously.

[0060] Furthermore, the fresh air device also includes: a fresh air body 340, which is installed on the indoor unit 100; a fresh air duct 310 located inside the fresh air body 340; a second air outlet 314, an outdoor air inlet 311, and an indoor air inlet 312 respectively installed on the fresh air body 340; and a filter element 350 installed inside the fresh air duct 310, at least a portion of which is positioned opposite to the outdoor air inlet 311 and the indoor air inlet 312, so that outdoor fresh air and / or indoor air flow through the filter element 350 for filtration before entering the indoor unit and / or the oxygen generating component 210.

[0061] The filter element 350 is installed within the fresh air duct 310, corresponding to the outdoor air inlet 311 and the indoor air inlet 312, ensuring that both outdoor fresh air and indoor air are effectively purified before entering the air conditioning system. This design can significantly reduce the content of pollutants and particulate matter in the air, improve indoor air quality, and create a healthier and more comfortable living or working environment for users.

[0062] The fresh air duct 310 is also equipped with a fan component 360, which is used to introduce outdoor fresh air into the fresh air duct 310 and exhaust it into the room through the first air outlet 313.

[0063] During the operation of the fresh air unit, outdoor fresh air is drawn into the first flow section 3150 and the second flow section 3151 through the first pipe 510. Part of it is discharged into the room through the first air outlet 313, and the other part flows into the second channel 316 and is drawn into the oxygen generating component 210 through the second pipe 520 to participate in oxygen generation. During this process, the outdoor fresh air is filtered by the filter component 350 in the fresh air unit, so that the air source filtration step of the oxygen generating component 210 is integrated with the fresh air filtration, which simplifies the structure. At the same time, since the fresh air unit is located in the indoor unit 100, it is also convenient to replace and clean the filter component 350.

[0064] In this application, as Figure 3 As shown, the fresh air main body 340 includes: a first body 341 and a second body 342. At least a portion of the fresh air duct 310 is enclosed by the first body 341 and the second body 342. An outdoor air inlet 311 is disposed on the first body 341, and an indoor air inlet 312 is disposed on the second body 342. The first body 341 and the second body 342 are connected at an angle, which is an acute angle. A switching component 400 is provided at the connection between the first body 341 and the second body 342. The switching component 400 is rotatably disposed to allow the outdoor air inlet 311 to open and the indoor air inlet 312 to close; or the indoor air inlet 312 to open and the outdoor air inlet 311 to close; or the outdoor air inlet 311 and the indoor air inlet 312 to open simultaneously.

[0065] The first body 341 and the second body 342 are connected at an acute angle. This compact design reduces the space occupied by the fresh air device. The acute angle connection design of the first body 341 and the second body 342 can also effectively guide and optimize the airflow path, so that when outdoor fresh air or indoor air enters the fresh air channel 310, it can move along a smoother angle, reducing airflow turbulence and resistance, and improving the efficiency and stability of airflow transmission.

[0066] The design of the switching component 400 allows it to rotate freely, enabling dynamic switching between the outdoor air inlet 311 and the indoor air inlet 312. It not only supports opening the outdoor air inlet to introduce fresh air, but also allows opening the indoor air inlet for air circulation. It can even open both at the same time under certain circumstances, providing the system with extremely high operational flexibility to cope with different environmental needs and usage scenarios.

[0067] like Figure 6 As shown, the switching component 400 includes: a rotating plate 410, which is rotatably disposed between the outdoor air inlet 311 and the indoor air inlet 312; and a driving member 420, which is drivenly connected to the rotating plate 410 to drive the rotating plate 410 to rotate.

[0068] The rotating plate 410 can be flexibly switched between the outdoor air inlet 311 and the indoor air inlet 312 by the drive of the drive component 420, so that the system can automatically or manually select to introduce fresh outdoor air or recirculated indoor air according to the actual needs of the indoor environment or the external weather conditions, which greatly increases the flexibility and applicability of the air conditioning system.

[0069] Driven by the drive unit 420, the rotating plate 410 can quickly complete the rotation operation, which means that the system can switch the air intake mode in a very short time, improving the system's response speed to environmental changes and providing users with more immediate and efficient air quality improvement services.

[0070] Preferably, the driving component 420 is a drive motor.

[0071] like Figure 8 As shown, this application also provides an air conditioner, including an indoor unit 100, an outdoor unit 200 and a fresh air device 300. At least a portion of the fresh air device 300 is disposed in the indoor unit 100, and an oxygen generating component 210 is disposed in the outdoor unit 200. The fresh air device 300 is connected to the oxygen generating component 210. The fresh air device 300 is the fresh air device of the above embodiment.

[0072] The fresh air unit is installed on one side of the indoor unit 100, and its main structure includes a fresh air duct 310 and a filter component 350. The fresh air duct 310 is equipped with an outdoor air inlet 311 and an indoor air inlet 312, and a rotatable switching component 400 is cleverly designed between the two air inlets. This switching component 400 adopts a rotary structure and can rotate left and right around a rotation axis to achieve the opening and closing switching between the air inlets.

[0073] One end of the rotating shaft is equipped with a drive motor to provide stable rotational power to the switching component 400. The motor is fixed to the periphery of the fresh air duct 310 of the fresh air body 340 by screws, and its output shaft is connected to the rotating shaft of the switching component 400, thereby transmitting power to the switching component 400 and ensuring its smooth operation.

[0074] The fresh air duct 310 is also designed with an oxygen intake port (i.e., the second air outlet 314), while the fresh air duct 310 is equipped with an indoor air outlet. As the core component of the airflow power, the fresh air fan drives the airflow through the filter screen for purification. Part of the air is delivered to the room through the indoor air outlet, while the other part enters the oxygen generation system through the oxygen generation duct, providing a clean air source for oxygen generation.

[0075] In practical applications, the fresh air unit can flexibly switch operating modes according to environmental conditions. When the indoor and outdoor temperature difference is small and the outdoor air quality is good, the system prioritizes activating the fresh air intake function, selecting outdoor air as the oxygen source. At this time, the switching component 400 switches to the indoor air inlet closed state, introducing outdoor fresh air. After filtration and purification, part of the fresh air enters the room through the air outlet, improving indoor air quality; the other part provides oxygen to the oxygen generation system through the oxygen generation channel, thereby improving oxygen generation efficiency. This mode achieves both fresh indoor air and ensures the efficient operation of the oxygen generation system.

[0076] When there is a large temperature difference between indoors and outdoors, or when outdoor air quality is poor, the system switches to indoor circulation mode. In this mode, the switching unit 400 adjusts to close the fresh air inlet and open the indoor air inlet, allowing the system to circulate, filter, and purify indoor air while providing a clean air source for oxygen production. This mode effectively avoids condensation caused by the entry of cold outdoor air and prevents heat loss due to large temperature differences, maintaining a stable indoor temperature. Furthermore, when outdoor air quality is poor, closing the fresh air inlet avoids frequent filter replacements due to external pollutants, further extending the filter's lifespan.

[0077] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0078] The fresh air device of this application is installed inside the indoor unit 100. The fresh air device includes a fresh air duct 310, which has an outdoor air inlet 311, an indoor air inlet 312, a first air outlet 313, and a second air outlet 314. The outdoor air inlet 311 is used to communicate with the outdoor environment to introduce outdoor fresh air into the fresh air duct 310; the indoor air inlet 312 is used to communicate with the indoor environment to introduce indoor air into the fresh air duct 310; the first air outlet 313 is used to communicate with the indoor environment. The environment is connected, and the second air outlet 314 is connected to the oxygen generating component 210, so that part of the fresh air in the fresh air duct 310 is discharged into the room through the first air outlet 313, and the other part is discharged into the oxygen generating component 210 through the second air outlet 314 for oxygen generation; wherein, the outdoor air inlet 311 and the indoor air inlet 312 can be selectively opened or closed, so that outdoor fresh air and indoor air are simultaneously introduced into the fresh air duct 310, or one of the outdoor fresh air or indoor air is introduced into the fresh air duct 310.

[0079] This configuration allows the fresh air unit to selectively draw air from either the outside or the inside, depending on the outdoor air quality and temperature, to supply the oxygen-generating component 210 with the necessary air source for oxygen production. When the outdoor temperature is too low, the indoor air circulation mode avoids energy loss caused by introducing cold air, ensuring that the produced oxygen does not affect the indoor temperature. When the outdoor air quality is poor, closing the outdoor air inlet 311 and using the indoor air inlet 312 for internal circulation also reduces the degree of contamination of the filter inside the fresh air unit. Furthermore, the oxygen-generating component 210 and the fresh air unit share the same air duct, enabling the fresh air unit to not only provide fresh air to the room but also supply air to the oxygen-generating component 210, reducing wear and tear on the functional components inside the oxygen-generating component 210 and extending the service life of each component.
