[0045] Figure 1 This is a schematic structural diagram of a fresh air purification device 100 according to an embodiment of the present invention, as shown below. Figure 1 As shown, and with reference Figures 2 to 6 This utility model provides a fresh air purification device 100. The fresh air purification device 100 includes a housing 110, a first inlet 120, a second inlet 130, a purification device 150, and an outlet 140.

[0046] An air duct for airflow is formed within the housing 110. A first inlet 120 is disposed on the housing 110 for introducing outdoor fresh air into the air duct. A second inlet 130 is disposed on the housing 110 for introducing indoor return air into the air duct. A purification device 150 is disposed within the air duct for purifying the outdoor fresh air and / or indoor return air flowing into the air duct. An outlet 140 faces the rear side of the housing 110 and communicates with the air duct for blowing the purified outdoor fresh air and / or indoor return air into the room.

[0047] The operation of the fresh air purification device 100 is as follows: outdoor fresh air flows into the air duct through the first inlet 120, while indoor return air merges into the same air duct through the second inlet 130, and the two airflows mix within the air duct; when the mixed airflow passes through the purification device 150 installed inside the air duct, particulate matter and harmful substances are removed through filtration or disinfection; the purified airflow is finally discharged directionally through the outlet 140 to the rear of the casing 110 for delivery to the indoor space. This fresh air purification device 100 achieves air circulation and purification while simultaneously introducing fresh air, effectively improving indoor air quality.

[0048] In this embodiment, on the one hand, the fresh air and indoor return air are mixed within the housing 110, which reduces the temperature difference between the air outlet of the fresh air purifier 100 and the indoor air; on the other hand, the outlet 140 of the fresh air purifier 100 faces the rear of the housing 110, preventing the airflow from the fresh air purifier 100 from being directly blown towards the user's activity area, thus eliminating the discomfort of direct airflow. Therefore, this embodiment significantly improves the user experience.

[0049] In this embodiment, the fresh air purification device 100 can be installed at the bottom inside the air conditioner 10, which is a cabinet air conditioner 10.

[0050] like Figures 1 to 4 As shown, furthermore, by controlling the opening and closing of the first inlet 120 and the second inlet 130, multiple air supply modes of the fresh air purification device 100 can be realized, thereby meeting the diverse usage needs of users.

[0051] like Figures 1 to 4 As shown, in some optional embodiments of this utility model, the first inlet 120 and the second inlet 130 are both disposed on the rear side of the housing 110, and the outlet 140 is disposed above the first inlet 120 and the second inlet 130.

[0052] In this embodiment, by placing the first inlet 120 and the second inlet 130 on the rear side of the housing 110, it is not only easier to manufacture, but also makes the appearance of the fresh air purification device 100 and the air conditioner 10 more concise and beautiful.

[0053] Furthermore, by positioning the outlet 140 above the first inlet 120 and the second inlet 130, the outlet 140 of the fresh air purification device 100 can be positioned close to the main air inlet of the air conditioner 10. The main air inlet is used to input indoor return air into the air conditioner 10, which facilitates the air blown out by the fresh air purification device 100 to enter the main air inlet and mix with the indoor return air. This mixed air can be blown into the room through the main air outlet of the air conditioner 10 after heat exchange, thereby increasing the air delivery distance of the purified air and thus promoting uniform indoor airflow.

[0054] In some optional embodiments of this utility model, the first inlet 120 and the second inlet 130 are spaced apart in the left-right direction.

[0055] In some optional embodiments of this utility model, the first inlet 120 and the second inlet 130 are arranged at intervals in the vertical direction. For example, the first inlet 120 is located below the second inlet 130; or, the first inlet 120 is located above the second inlet 130.

[0056] like Figures 1 to 4 As shown, preferably, the first inlet 120 is positioned above the second inlet 130. This arrangement allows the second inlet 130 to be located away from the outlet 140, which helps to avoid airflow short-circuiting, i.e., prevents the air outlet 140 from being drawn back into the second inlet 130, thereby improving ventilation efficiency.

[0057] like Figures 1 to 4 As shown, in some optional embodiments of this utility model, the opening area of ​​the first inlet 120 is smaller than the opening area of ​​the second inlet 130.

[0058] In this embodiment, by limiting the proportion of fresh air intake, the amount of fresh air is relatively small and the amount of return air is relatively large, which is conducive to improving the overall purification and filtration efficiency of indoor air and also helps to maintain indoor pressure balance.

[0059] like Figures 1 to 4 As shown, in some optional embodiments of this utility model, the housing 110 is provided with a fresh air interface, which forms a first inlet 120 for connecting to a fresh air duct. The second inlet 130 is an elongated strip structure extending along the left-right direction of the housing 110.

[0060] In this embodiment, the installation and connection between the fresh air duct and the first inlet 120 is simplified by setting a fresh air interface. The elongated second inlet 130 can reduce the vertical dimension of the second inlet 130 while maintaining a certain air intake area, which is more conducive to keeping the second inlet 130 away from the outlet 140 and better avoiding airflow short-circuiting.

[0061] like Figure 5 As shown, in some optional embodiments of this utility model, the fresh air purification device 100 further includes a centrifugal fan 160, which is disposed within the air duct, and the rotation axis of the centrifugal fan 160 extends in the front-to-back direction. The centrifugal fan 160 has an air intake port and an air exhaust port, the air intake port being connected to the first inlet 120 and the second inlet 130, and the air exhaust port being connected to the outlet 140. Specifically, within the air duct, the centrifugal fan 160 can be disposed upstream or downstream of the purification device 150; that is, the purification device 150 can be disposed at the air intake port of the centrifugal fan 160 or at the air exhaust port of the centrifugal fan 160.

[0062] In this embodiment, the rotation axis of the centrifugal fan 160 extends in the front-to-back direction, which not only makes the structure of the fresh air purification device 100 compact, but also significantly improves the mixing efficiency of fresh air and return air through the high air pressure and large flow characteristics of the centrifugal fan 160. At the same time, it simultaneously draws in two airflows and pressurizes and integrates them to ensure that the airflow overcomes resistance and is delivered stably when it penetrates the purification module.

[0063] like Figure 5 As shown, in some optional embodiments of this utility model, the purification device 150 is disposed upstream of the air intake in the air duct. The exhaust port of the centrifugal fan 160 is disposed at its top. The fresh air purification device 100 also includes an air outlet structure 180, one end of which is connected to the exhaust port, and the other end faces the rear side of the housing 110 and forms the outlet 140 of the fresh air purification device 100.

[0064] During use, under the action of centrifugal fan 160, outdoor fresh air and indoor return air enter the duct section, and the two airflows mix in the duct; then they are purified by purification device 150, and enter the air outlet structure 180 through centrifugal fan 160, and are discharged to the rear of fresh air purification device 100.

[0065] In this embodiment, the purification device 150 is located upstream of the air intake of the centrifugal fan 160, which may allow the air to be purified before entering the centrifugal fan 160. In this way, the centrifugal fan 160 processes clean air, reduces dust accumulation, and extends its service life.

[0066] like Figure 5 As shown, in some optional embodiments of this utility model, the centrifugal fan 160 is mounted on the volute bracket 164, and the volute bracket 164 is provided with a first through hole 1641 corresponding to the air intake. Specifically, the volute bracket 164 has a square structure.

[0067] The centrifugal fan 160 includes a volute and a centrifugal impeller 163. The centrifugal impeller 163 is disposed within the volute. The volute includes a first volute 161 and a second volute 162. The first volute 161 is disposed on the front side of the centrifugal impeller 163, and the second volute 162 is disposed on the rear side of the centrifugal impeller 163. An intake port is formed on the first volute 161, and an exhaust port is formed on the top of the first volute 161 and the second volute 162. Specifically, the first volute 161 and the second volute 162 are detachably connected.

[0068] The fresh air purification device 100 also includes a first motor 170, which is disposed on the front side of the second volute 162. The first motor 170 is mounted on the second volute 162 via a motor bracket 171. The second volute 162 has a second through hole, through which the output shaft of the first motor 170 passes and connects to the centrifugal impeller 163. The fresh air purification device 100 also includes an electrical enclosure 190, which is electrically connected to the first motor 170 and disposed on the front side of the second volute 162, shielding the second volute 162. The electrical enclosure 190 has a plug-in portion, and the second volute 162 and the first volute 161 have corresponding plug-in mating portions. Alternatively, the electrical enclosure 190 and the second volute 162 are connected by threads.

[0069] In this embodiment, the split volute design facilitates assembly and maintenance. The electrical enclosure 190 can be quickly positioned and installed with the volute via a plug-in connector. The electrical enclosure 190 conceals the rear side of the second volute 162, which is both aesthetically pleasing and dustproof, and can extend the equipment's lifespan.

[0070] In some optional embodiments of this utility model, the motor bracket 171 and the second volute 162 can be connected by threads. Specifically, the motor bracket 171 includes multiple legs, which are evenly distributed around the second through hole. Each leg is provided with a first threaded hole. The second volute 162 is provided with multiple second threaded holes, which are arranged in a one-to-one correspondence with the first threaded holes. The second threaded holes and the first threaded holes are connected by screws.

[0071] In some optional embodiments of this utility model, the air outlet structure includes a detachably connected first part 181 and a second part 182. That is, the air outlet structure is formed by the first part 181 and the second part 182. The first part 181 and the second part 182 are distributed in the left-right direction, and the two can be connected by threads or snapped together.

[0072] like Figure 5 As shown, in some optional embodiments of this utility model, the purification device 150 includes a filter screen that blocks the first inlet 120 and the second inlet 130. In this embodiment, the filter screen covers both the fresh air and return air inlets, resulting in a large filtration area and good filtration effect.

[0073] Furthermore, the filter can be a HEPA filter or an IFD filter. HEPA stands for High Efficiency Particulate Air Filter, which effectively filters particles larger than 0.3 microns. IFD stands for Intense Field Dielectric Air Filter, which uses an electrostatic field to adsorb charged particles.

[0074] like Figure 5 As shown, in some optional embodiments of this utility model, the filter screen is perpendicular to the flow direction of the airflow in the duct.

[0075] like Figure 5 As shown, in some optional embodiments of this utility model, the bottom of the housing 110 is provided with a guide rail 111, the purification device 150 is installed in the guide rail 111, and one end of the guide rail 111 is provided with a notch for the purification device 150 to pass through. Preferably, the guide rail 111 extends in the left-right direction.

[0076] In this embodiment, on the one hand, the guide rail 111 precisely limits the positioning to ensure that the purification device 150 is quickly aligned and stably supported during installation, avoiding displacement or loosening. On the other hand, the notch at the end of the guide rail 111 forms an unobstructed pull-out channel, allowing the purification device 150 to be directly installed or removed without disassembling other components, greatly simplifying the subsequent maintenance, cleaning, and replacement process.

[0077] Specifically, the housing 110 has a clearance hole for the purification device 150 to pass through; the clearance hole corresponds to the notch of the guide rail 111. The purification device 150 also includes a mounting bracket, on which the filter screen is mounted. The mounting bracket has a handle or recess on the side near the notch to facilitate the assembly or disassembly of the mounting bracket.

[0078] like Figure 5 As shown, in some optional embodiments of this utility model, the housing 110 includes a rear housing portion 112 with an extended opening, and the rear housing portion 112 is snap-fitted to the volute support 164. A guide rail 111 is disposed at the bottom of the rear housing portion 112, and a first inlet 120 and a second inlet 130 are disposed on the rear sidewall of the rear housing portion 112.

[0079] like Figures 1 to 5 As shown, in some optional embodiments of this utility model, the fresh air purification device 100 further includes a first guide plate 121 and a second guide plate 131.

[0080] The first guide plate 121 is rotatably disposed at the first inlet 120 so that the first inlet 120 can be closed or opened. The first guide plate 121 includes a first plate body and a first rotating shaft, the first rotating shaft being rotatably connected to the housing 110; the first rotating shaft is connected to the middle part of the first plate body.

[0081] The second guide plate 131 is rotatably disposed at the second inlet 130 so that the second inlet 130 is closed or open; the second guide plate 131 includes a second plate body and a second rotating shaft, the second rotating shaft being rotatably connected to the housing 110; the second rotating shaft is connected to the middle part of the second plate body.

[0082] In this embodiment, the dual guide plates independently control the opening and closing of the first inlet 120 and the second inlet 130 to achieve a pure fresh air mode (e.g., Figure 4 As shown, turn off return air), internal circulation mode (such as...) Figure 2 As shown, turn off the fresh air intake) and the mixed mode (such as...) Figure 3 The flexible switching (as shown) adapts to different air quality requirements, while effectively preventing dust when closed.

[0083] Furthermore, the first guide plate 121 is connected to a second motor 122 for driving the first rotating shaft to rotate; the second guide plate 131 is connected to a third motor 132 for driving the second rotating shaft to rotate.

[0084] like Figure 6As shown, this utility model also provides an air conditioner 10, which includes a body 200 and a fresh air purification device 100 as described in any of the above embodiments. The fresh air purification device 100 is disposed inside the body 200. The body 200 is provided with a first air inlet, and the rear wall of the body 200 is provided with a first air outlet; the first air inlet is connected to a first inlet 120 and a second inlet 130 respectively, and the first air outlet is connected to an outlet 140.

[0085] In some optional embodiments of this utility model, the body 200 extends vertically, and the air conditioner 10 is a vertical air conditioner 10. The fresh air purification device 100 is disposed in the lower part of the body 200. A main air inlet is also provided on the rear wall of the body 200, which is located above the first air outlet; a main air outlet is provided on the front wall of the body 200.

[0086] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
