Detailed implementation manners

[0041] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0042] The present invention provides a fresh air system, please refer to Figures 1 to 19 , comprising: a shell 1; a first fan assembly 2, which is arranged in the shell 1, and the first fan assembly 2 has a first air guide channel 20, and the indoor air flow is guided to the outside through the first air guide channel 20; a second fan assembly 3, which is arranged in the shell 1, and the second fan assembly 3 has a second air guide channel 30, and the outdoor air flow is guided to the room through the second air guide channel 30; a first baffle 4, which is adjustably arranged between the first air guide channel 20 and the second air guide channel 30 to isolate or connect the first air guide channel 20 and the second air guide channel 30.

[0043] According to the present invention, the fresh air system includes a housing 1, a first fan assembly 2, a second fan assembly 3 and a first baffle 4. The first fan assembly 2 is arranged in the housing 1, and the first fan assembly 2 has a first air guide channel 20, through which the indoor air flow is guided to the outside; the second fan assembly 3 is arranged in the housing 1, and the second fan assembly 3 has a second air guide channel 30, through which the outdoor air flow is guided to the room; the first baffle 4 is adjustable in position between the first air guide channel 20 and the second air guide channel 30, so that the first air guide channel 20 and the second air guide channel 30 are isolated or connected. In this way, the position of the first baffle 4 can be adjusted, so that the first air guide channel 20 and the second air guide channel 30 can be independently operated or connected. When the first air guide channel 20 is connected to the second air guide channel 30, the first fan assembly 2 and the second fan assembly 3 both introduce outdoor fresh air into the room, thereby increasing the indoor fresh air volume and improving the user's comfort.

[0044] The fresh air system further includes: an exhaust passage 14, which is arranged on the housing 1, and the exhaust passage 14 is connected to the first air guide passage 20, and the first baffle 4 is located between the exhaust passage 14 and the second air guide passage 30, so that when the first air guide passage 20 is connected to the second air guide passage 30, the first baffle 4 blocks the inlet end of the exhaust passage 14. When the first air guide passage 20 is connected to the second air guide passage 30, the exhaust passage 14 is disconnected from the first air guide passage 20, so as to avoid airflow from flowing and affecting the air outlet efficiency.

[0045] Specifically, the fresh air system further includes: a rear cover 5, which is arranged on the housing 1. The rear cover 5 is provided with a first communication cavity 51 and a second communication cavity 52. The first communication cavity 51 is communicated with the first air guiding channel 20, and the second communication cavity 52 is communicated with the second air guiding channel 30. Such a setting is to realize the independent operation of the first air guiding channel 20 and the second air guiding channel 30 respectively.

[0046] In a specific implementation, the fresh air system further includes: a second baffle 6, which is arranged on the rear cover 5 and located between the first communication cavity 51 and the second communication cavity 52. The second baffle 6 has a blocking position and an avoidance position, and the second baffle 6 is movably arranged between the blocking position and the avoidance position, so that the first communication cavity 51 is communicated with the second communication cavity 52, or the first communication cavity 51 and the second communication cavity 52 are in an open circuit. Such a setting can control the conduction or open circuit between the first communication cavity 51 and the second communication cavity 52 according to the user's usage requirements, so that the fresh air system is in an internal circulation mode, an exhaust mode or an air intake mode.

[0047] In order to further control the conduction state of the first communication cavity 51, the rear cover 5 is provided with a first air outlet 53 and a second air outlet 54. The first air outlet 53 is communicated with the first communication cavity 51, and the second air outlet 54 is communicated with the second communication cavity 52. The fresh air system further includes: a third baffle 7, which is arranged at the first air outlet 53. The third baffle 7 has an open position and a closed position, and the third baffle 7 is movably arranged between the open position and the closed position, so that the first air outlet 53 is opened or closed.

[0048] Among them, in order to further control the conduction state of the second communication cavity 52, the fresh air system further includes: a fourth baffle 8, which is arranged at the second air outlet 54. The fourth baffle 8 has an open position and a closed position, and the fourth baffle 8 is movably arranged between the open position and the closed position, so that the second air outlet 54 is opened or closed.

[0049] In the embodiment provided by the present invention, the fresh air system further includes: a transition component 9, which is arranged on the side of the rear cover 5. The transition component 9 includes a first chamber 91 and a second chamber 92. The first chamber 91 is communicated with the first air guiding channel 20, the second chamber 92 is communicated with the second air guiding channel 30, and the second communication cavity 52 is communicated with the first chamber 91. Among them, by setting the transition component 9, when the fresh air system is in an increased fresh air volume mode or an internal circulation mode, it plays a role of converging or transitioning the air flow. Especially in the internal circulation mode, the air flow in the first air guiding channel 20 flows through the first chamber 91 and the second chamber 92 in sequence, and then flows into the second air guiding channel 30 after being filtered by the filtering component 11.

[0050] To facilitate controlling the connection or disconnection between the first chamber 91 and the second chamber 92, the fresh air system further includes: a fifth baffle 10 disposed on the transition member 9 and located between the first chamber 91 and the second chamber 92. The fifth baffle 10 has a blocking position and a conducting position, and the fifth baffle 10 is movably disposed between the blocking position and the conducting position so that the first chamber 91 and the second chamber 92 are in a disconnected state, or the first chamber 91 and the second chamber 92 are connected.

[0051] Specifically, as Figure 5 shown, a third air outlet 93 is provided on the transition member 9, and the first chamber 91 communicates with the first air guiding channel 20 through the third air outlet 93. A fourth air outlet 94 is provided on the transition member 9, and the second chamber 92 communicates with the second air guiding channel 30 through the fourth air outlet 94. A fifth air outlet 95 is provided on the transition member 9, and the first chamber 91 communicates with the fifth air outlet 95. The indoor air flow flows into the first chamber 91 after passing through the fifth air outlet 95 and is then discharged under the guiding action of the first fan assembly 2.

[0052] The fresh air system further includes: a filtering member 11, at least a part of the filtering member 11 is disposed between the rear cover 5 and the transition member 9, and the filtering member 11 faces the second chamber 92. In this way, after the air flow passes through the second communication chamber 52, the impurities in the outdoor fresh air are filtered by the filtering member 11, and then the fresh air flows into the room, improving the quality of the indoor fresh air.

[0053] The present invention also provides an air conditioner, including a body 100 and a fresh air system 200. The fresh air system 200 is installed in the body 100, and the fresh air system 200 is the above-mentioned fresh air system 200. A first opening 101, a second opening 102, and a third opening 103 are provided on the panel of the body 100. The first opening 101 faces the air outlet 12, the second opening 102 faces the air inlet 13, and the third opening 103 faces the fifth air outlet 95.

[0054] During actual application, when the first baffle 4, the fourth baffle 8, and the fifth baffle 10 are all in the blocking position, and the second baffle 6 and the third baffle 7 are in the open position, as Figure 6 shown, the second communication chamber 52 communicates with the second chamber 92, and the air conditioner is in the air inlet mode. The outdoor fresh air is introduced into the room after passing through the air inlet 13. As Figure 9 shown, the first air guiding channel 20 communicates with the first chamber 91 and the first communication chamber 51, and the air conditioner is in the air exhaust mode. The indoor turbid air flows into the first air guiding channel 20 through the fifth air outlet 95 and is then discharged to the outside through the air outlet 12 of the air exhaust channel 14.

[0055] When the second baffle 6 is in the blocking position and the first baffle 4, the third baffle 7, the fourth baffle 8 and the fifth baffle 10 are in the open position, at this time, the first chamber 91 and the second chamber 92 are communicated, the first air guiding channel 20 and the second air guiding channel 30 are communicated, the fifth air outlet 95 is closed, the inlet end of the air exhaust channel of the first baffle 4 is blocked, the first fan assembly 2 and the second fan assembly 3 work simultaneously. After the air flow is introduced into the second chamber 92 through the air inlet 13, under the action of the first fan assembly 2, a part of the air flow is introduced into the first chamber 91, then flows into the second air guiding channel 30 through the first air guiding channel 20, and then flows into the room, so that the air conditioner is in the mode of increasing the fresh air volume.

[0056] When the first baffle 4, the third baffle 7, the fourth baffle 8 and the fifth baffle 10 are in the blocking position and the second baffle 6 is in the open position, as Figure 14 and Figure 15 shown, at this time, the indoor air flow flows into the first communication cavity 51 after flowing through the first air guiding channel 20, flows into the second communication cavity 52 from the first communication cavity 51, and then flows into the room after flowing through the filtering component 11, so that the air conditioner is in the internal circulation mode.

[0057] When the first baffle, the third baffle 7 and the fifth baffle 10 are in the blocking position and the fourth baffle 8 and the second baffle 6 are in the open position, the first communication cavity 51 and the second communication cavity 52 are conducted. After the indoor air flow flows through the first air guiding channel 20, it is mixed with the fresh air in the second communication cavity 52 and then flows into the room after flowing through the filtering component 11. At this time, the fresh air is mixed with the indoor air flow to increase the temperature of the fresh air, avoiding the direct blowing of the relatively cold fresh air to the user and improving the user's comfort.

[0058] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0059] The fresh air system provided by the present invention includes a housing 1, a first fan assembly 2, a second fan assembly 3, and a first baffle 4. The first fan assembly 2 is disposed inside the housing 1 and has a first air guiding channel 20 through which indoor air flow is led to the outside. The second fan assembly 3 is disposed inside the housing 1 and has a second air guiding channel 30 through which outdoor air flow is introduced into the room. The first baffle 4 is adjustably disposed between the first air guiding channel 20 and the second air guiding channel 30 to isolate or connect the first air guiding channel 20 and the second air guiding channel 30. With such an arrangement, by adjusting the position of the first baffle 4, the first air guiding channel 20 and the second air guiding channel 30 can operate independently or be connected. When the first air guiding channel 20 is connected to the second air guiding channel 30, both the first fan assembly 2 and the second fan assembly 3 introduce outdoor fresh air into the room, increasing the fresh air volume in the room and improving the user's comfort level.

[0060] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
