[0039] Unless otherwise stated, the term "plurality" means two or more.

[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0041] Combine Figure 1-7 As shown, the embodiment of the present disclosure provides a fresh air component for air conditioning, including: a connecting box 100 and a valve 200. The connecting box 100 is provided with an internal circulation air inlet 101, a fresh air inlet 102 and an air outlet 103; the valve 200 includes a first shielding portion 210 for closing or opening the fresh air inlet 102 and a second shielding portion 220 for closing or opening the internal circulation air inlet 101; wherein, when the valve 200 moves from the first position to the second position, the first shielding portion 210 changes from opening the fresh air inlet 102 to closing the fresh air inlet 102, and the second shielding portion 220 changes from closing the internal circulation air inlet 101 to opening the internal circulation air inlet 101.

[0042] The fresh air assembly for an air conditioner provided by the disclosed embodiments can adjust the positions of the first and second shielding portions 210 and 220 by controlling the valve 200 from a first position to a second position, thereby adjusting the state of the fresh air inlet 102 and the state of the internal circulation air inlet 101, thereby changing the air supply mode. This reduces the number of components required for control, lowers the risk of failure during long-term operation, and improves the user experience.

[0043] Optionally, the valve 200 is movably arranged inside the communication box 100. In this way, the valve 200 is arranged inside the communication box 100, does not occupy too much space outside the communication box 100, and the communication box 100 can provide protection for the valve 200, reducing the risk of interference with the valve 200 during movement.

[0044] Combine Figure 3As shown, the second shielding portion 220 optionally includes a second movable plate 221. The second movable plate 221 is fixedly connected to the first shielding portion 210 and is provided with a first ventilation hole 222 and a second ventilation hole 223. The first ventilation hole 222 and the second ventilation hole 223 can both communicate with the internal circulation air inlet 101. When the valve 200 is in the second position, the second ventilation hole 223 communicates with the internal circulation air inlet 101. Thus, when the valve 200 is in the first position, the second movable plate 221 blocks the internal circulation air inlet 101, and the first shielding portion 210 opens the fresh air inlet 102, achieving the fresh air mode. When the valve 200 moves from the first position to the second position, the fresh air inlet 102 is blocked by the first shielding portion 210, and the second ventilation hole 223 communicates with the internal circulation air inlet 101, achieving the indoor circulation mode. When the valve 200 moves to the third position, the fresh air inlet 102 is closed by the first shielding portion 210, and the internal circulation air inlet 101 is closed by the movable plate. When the valve 200 moves from the third position to the fourth position, the fresh air inlet 102 gradually changes from a closed state to an open state, and the first ventilation hole 222 is connected to the internal circulation air inlet 101, realizing a mixed air mode, and the air intake volume of the outdoor air flow can be dynamically adjusted. It can be seen that a variety of circulation modes can be realized to meet the different air supply needs of users. In addition, the number of components required to be controlled is relatively small, which reduces the risk of failure during long-term operation and has relatively high reliability.

[0045] It can be understood that in the process of the valve 200 moving from the third position to the fourth position, the opening of the fresh air inlet 102 changes from small to large, and the internal circulation air inlet 101 is first connected to the second ventilation hole 223, and as the valve 200 moves, the internal circulation air inlet 101 is then connected to the first ventilation hole 222.

[0046] Optionally, the first ventilation hole 222 and the second ventilation hole 223 are respectively located at two opposite ends of the second movable plate 221. In this way, there is a gap between the first ventilation hole 222 and the second ventilation hole 223, which facilitates the adjustment of the state of the internal circulation air inlet 101 during the movement of the valve 200, ensuring flexible adjustment between multiple circulation modes.

[0047] Optionally, multiple first ventilation holes 222, multiple second ventilation holes 223, and multiple internal circulation air inlets 101 are provided, and multiple first ventilation holes 222 and multiple internal circulation air inlets 101 can be partially or fully connected, and multiple second ventilation holes 223 and multiple internal circulation air inlets 101 can be partially or fully connected. In this way, by partially or fully connecting multiple first ventilation holes 222 and multiple internal circulation air inlets 101, and partially or fully connecting multiple second ventilation holes 223 and multiple internal circulation air inlets 101, the air intake volume of the internal circulation air inlet 101 can be adjusted. In the mixed air mode, the ratio with the outdoor air intake volume can be adjusted, the temperature of the air flow blowing into the room can be adjusted, and the risk of large fluctuations in indoor temperature in a short period of time can be reduced.

[0048] Specifically, a portion of the plurality of internal circulation air inlets 101 can communicate with a portion of the plurality of first ventilation holes 222, and a portion of the remaining portion of the plurality of internal circulation air inlets 101 can communicate with a portion of the plurality of second ventilation holes 223. In this way, when the valve 200 moves from the second position to the third position, the air intake of the internal circulation air inlet 101 is guaranteed.

[0049] Specifically, there are three first ventilation holes 222 and three second ventilation holes 223 , and there are four internal circulation air inlets 101 .

[0050] Specifically, two of the four internal circulation air inlets 101 can be communicated with two of the three first ventilation holes 222 , and one of the remaining four internal circulation air inlets 101 can be communicated with one of the three second ventilation holes 223 .

[0051] It can be understood that two of the four internal circulation air inlets 101 can be connected to one of the three first ventilation holes 222, and one of the remaining four internal circulation air inlets 101 can be connected to two of the three second ventilation holes 223.

[0052] Specifically, the first ventilation hole 222, the second ventilation hole 223 and the internal circulation air inlet 101 are all rectangular holes.

[0053] Optionally, the connecting box 100 is provided with a side wall of an internal circulation air inlet 101, which is arranged perpendicular to the side wall provided with the fresh air inlet 102. In this way, the direction of the airflow entering from the internal circulation air inlet 101 and the direction of the airflow entering from the fresh air inlet 102 form an angle, so that the two airflows can better intersect and mix.

[0054] Optionally, the first shielding portion 210 and the second shielding portion 220 are arranged vertically. In this way, they are adapted to the fresh air inlet 102 and the internal circulation air inlet 101 on the connecting box 100, and when the fresh air inlet 102 and the internal circulation air inlet 101 are closed, the risk of air leakage is reduced.

[0055] Optionally, the first shielding portion 210 is slidably connected to one side wall of the communication box 100, and the second shielding portion 220 is slidably abutted against the other adjacent side wall of the communication box 100. In this way, the first shielding portion 210 and the second shielding portion 220 can better fit the side wall of the communication box 100, reducing the risk of air leakage when the fresh air inlet 102 and the internal circulation air inlet 101 are closed.

[0056] Optionally, the second movable plate 221 is disposed inside the communication box 100 and is in sliding contact with an inner wall of the communication box 100. Thus, the second movable plate 221 is located inside the communication box 100, and the communication box 100 provides protection for the second movable plate 221, reducing the risk of interference with the second movable plate 221. This reduces the risk of air leakage when the internal circulation air inlet 101 is sealed.

[0057] Optionally, the first shielding portion 210 includes a first movable plate 211. The first movable plate 211 slidably abuts against an inner sidewall of the communication box 100 to open or close the fresh air inlet 102. The first movable plate 211 is fixedly connected to the second shielding portion 220. Thus, the first movable plate 211 is located inside the communication box 100, and the communication box 100 provides protection for the first movable plate 211, reducing the risk of interference with the first movable plate 211. Furthermore, when the fresh air inlet 102 is closed, the risk of air leakage is reduced.

[0058] Specifically, the first movable plate 211 and the second movable plate 221 are vertically arranged and fixedly connected.

[0059] Combine Figure 8 As shown, optionally, a guide assembly 300 is provided on the side wall of the communication box 100 to provide guidance for the first shielding portion 210. The guide assembly 300 is disposed on the side of the first shielding portion 210 facing away from the fresh air inlet 102. In this way, the guide assembly 300 provides guidance and position limiting for the first shielding portion 210, reducing the risk of the valve 200 shifting during movement.

[0060] Optionally, the guide assembly 300 includes a guide bar 310. The guide bar 310 is fixedly connected to the inner sidewall of the communication box 100 and extends along the sliding direction of the first movable plate 211. The guide bar 310 cooperates with the inner sidewall of the communication box 100 to provide a position limit and guide for the first movable plate 211 as it slides within the communication box 100. Thus, the guide bar 310 cooperates with the inner sidewall of the communication box 100 to provide a position limit and guide for the first movable plate 211, reducing the risk of the first movable plate 211 shifting during movement.

[0061] Optionally, the rim of the fresh air inlet 102 protrudes axially from the connecting box 100. Thus, since the fresh air inlet 102 needs to be connected to the fresh air duct to connect the connecting box 100 to the outside, the rim of the fresh air inlet 102 protrudes from the surface of the connecting box 100, facilitating installation of the fresh air duct and providing relatively high connection stability.

[0062] Combine Figure 8 As shown, the communication box 100 optionally includes a box body 110 and a cover plate 120. One side wall of the box body 110 is open, and the box body 110 is provided with an internal circulation air inlet 101 and a fresh air inlet 102. The cover plate 120 covers the open area and is provided with an air outlet 103. This allows the cover plate 120 to be opened from the box body 110, facilitating maintenance and replacement of components within the box body 110, as well as cleaning dust and dirt within the box body 110.

[0063] Combine Figure 9 As shown, the cover plate 120 is optionally connected to the box body 110 via a snap assembly 400. The snap assembly 400 includes a snap ring 410 and a snap protrusion 420, one of which is provided on the box body 110 and the other on the cover plate 120. Thus, by cooperating with the snap ring 410 and the snap protrusion 420, the cover plate 120 can be quickly removed from the box body 110 or quickly snapped onto the box body 110. This facilitates maintenance and replacement of components within the box body 110, as well as cleaning of dust and dirt within the box body 110.

[0064] Specifically, the snap ring 410 is connected to the cover 120, and the snap protrusion 420 is connected to the box body 110. Thus, by cooperating with the snap ring 410 and the snap protrusion 420, the cover 120 can be quickly removed from the box body 110, or quickly snapped onto the box body 110. This facilitates maintenance and replacement of components within the box body 110, as well as cleaning of dust and dirt within the box body 110.

[0065] Specifically, the opening of the box body 110 and the internal circulation air inlet 101 are respectively arranged on two opposite side walls of the box body 110 .

[0066] Specifically, the fresh air inlet 102 is provided on a side wall of the box body 110 adjacent to the internal circulation air inlet 101 .

[0067] Specifically, the guide strip 310 is fixedly connected to the cover plate 120 .

[0068] Optionally, the air inlet direction of the internal circulation air inlet 101 is perpendicular to the air inlet direction of the fresh air inlet 102. In this way, the airflow at the internal circulation air inlet 101 and the airflow at the fresh air inlet 102 intersect vertically, and the mixing effect is better.

[0069] Optionally, the air conditioner further includes a filter assembly 500. The filter assembly 500 is inserted into the communication box 100 perpendicular to the air outlet direction of the air outlet 103, and the filter assembly 500 is placed over the air outlet 103. In this way, the filter assembly 500 can filter both outdoor and indoor air, eliminating the need for separate filters for indoor and outdoor air. This reduces production costs while ensuring effective filtering, and also reduces the size and weight of the air conditioner.

[0070] Optionally, the filter assembly 500 includes a filter frame 510 and a filter element 520. The filter frame 510 is inserted into the communication box 100 in a direction perpendicular to the air flow from the air outlet 103. The filter element 520 is inserted into the filter frame 510 to filter the air flow from the air outlet 103. Because the filter element 520 is made of a relatively soft material, the filter element 520 is installed in the filter frame 510, and the filter frame 510 provides support for the filter element 520, thereby ensuring the filtering effect of the filter element 520.

[0071] Combine Figure 10 As shown, optionally, a driving assembly 600 is provided on one side of the communication box 100, and the driving assembly 600 is used to drive the valve 200 to move in the communication box 100. In this way, the driving assembly 600 provides power for the movement of the valve 200.

[0072] Optionally, the drive assembly 600 includes a drive motor 610 and a gear 620. The drive motor 610 is disposed outside the communication box 100. The output end of the drive motor 610 is connected to the gear 620. The gear 620 extends into the communication box 100 and engages with a side wall of the valve 200. In this way, the drive motor 610 provides power for the rotation of the gear 620, which in turn drives the valve 200 to move within the communication box 100.

[0073] Specifically, the gear 620 is engaged with a side wall of the first movable plate 211 facing the fresh air inlet 102 .

[0074] Optionally, a fan 700 is provided on the air outlet 103 side of the communication box 100. In this way, the air flow speed in the communication box 100 is increased by the fan 700, and one fan 700 can adapt to the indoor circulation mode, fresh air mode and mixed air mode at the same time, and the production cost is relatively low.

[0075] In some embodiments, an air conditioner includes: a fresh air component for an air conditioner as described in the above embodiments.

[0076] With the air conditioner provided in the embodiments of the present disclosure, since the air conditioner includes the fresh air assembly for air conditioning as described in the above-mentioned embodiment, the positions of the first shielding portion 210 and the second shielding portion 220 can be adjusted by controlling the valve 200 from a first position to a second position, thereby adjusting the state of the fresh air inlet 102 and the state of the internal circulation air inlet 101, thereby changing the air supply mode. This reduces the number of components required for control, reduces the risk of failure during long-term operation, and improves the user experience.

[0077] The above description and the accompanying drawings sufficiently illustrate the embodiments of the present disclosure to enable those skilled in the art to practice them.
