[0040] In order to solve the problem that when the temperature or humidity difference between indoor and outdoor is relatively large, the existing fresh air air conditioner directly introduces outdoor fresh air into the room, which will cause significant changes in the original temperature, humidity or other parameters of the room, easily causing discomfort to users and affecting the user experience.

[0041] like Figure 1 and Figure 2 As shown, this embodiment discloses a fresh air air conditioner, which includes an outdoor unit and an indoor unit, and the outdoor unit is connected to the indoor unit through a pipeline. The indoor unit includes a shell and a fresh air module installed in the shell, and the shell is provided with an air inlet and at least one air outlet, and the indoor air can enter the fresh air module through the air inlet. Specifically, the fresh air module includes a fresh air fan 1, an air mixing chamber 2, a filter 3, an air mixing structure, a fresh air duct 5 and an air outlet duct 6, the air outlet of the fresh air fan 1 is connected to the air outlet duct 6, the air inlet of the fresh air fan 1 is connected to the air outlet of the air mixing chamber 2, the filter 3 is installed in the air mixing chamber 2, the air mixing structure is installed at the air inlet of the air mixing chamber 2, and the fresh air duct 5 is connected to the air mixing structure.

[0042] Start the fresh air fan 1 to introduce outdoor fresh air and indoor air into the mixed air structure for preliminary mixing, and then enter the mixed air chamber 2 for further mixing after being filtered by the filter 3, so that the temperature difference between the fresh air and the indoor air is reduced, and then supplied into the room through the air outlet pipe 6 and the air outlet, thereby improving the user's comfort. At the same time, as the fresh air volume increases, the indoor air quality is gradually improved.

[0043] like Figures 1 to 4 As shown, the air mixing structure includes a bracket 41, a baffle 42 and a driving mechanism. The bracket 41 is installed on the air mixing chamber 2 and closes the air inlet of the air mixing chamber 2. The bracket 41 is provided with a fresh air inlet and an indoor air inlet 412. The indoor air inlet 412 is located on one side of the fresh air inlet. A fresh air pipe joint 46 is integrally formed in the fresh air inlet. One end of the fresh air pipe 5 is connected to the fresh air pipe joint 46, and the other end extends to the outdoors through the shell and the wall. The outdoor fresh air can flow to the area in front of the filter 3 through the fresh air pipe 5 and the fresh air joint, and is preliminarily mixed with the indoor air flowing through the indoor air inlet 412.

[0044] like Figures 2 to 4 As shown, the baffle 42 is located between the air inlet of the air mixing chamber 2 and the bracket 41, and a plurality of guide blocks 44 are integrally formed on the baffle 42. The bracket 41 is provided with a guide groove 411, and the guide blocks 44 are inserted into the guide groove 411 so that the baffle 42 can slide in the guide groove 411. The baffle 42 can be driven by a driving mechanism to move between the indoor air inlet 412 and the fresh air inlet to close or open the fresh air inlet.

[0045] The driving mechanism includes a driving motor 451 and a transmission assembly, and the transmission assembly includes a gear 452 and a rack 453. The driving motor 451 is installed on the bracket 41, and the gear 452 is coaxially connected to the output shaft of the driving motor 451. The rack 453 is fixed on the baffle 42, and the gear 452 is meshed with the rack 453. The driving motor 451 is started to drive the gear 452 to rotate, so that the rack 453 can drive the baffle 42 to move. By controlling the forward and reverse rotation of the driving motor 451, the baffle 42 can be reciprocated between the indoor air inlet 412 and the fresh air inlet.

[0046] like Figures 1 to 4 As shown, a blocking edge 43 is fixed on the side of the baffle plate 42 facing the bracket 41, and the blocking edge 43 fits with the bracket 41. A clearance notch 461 is provided on the fresh air pipe joint 46 for the blocking edge 43 to be inserted into. In this embodiment, the blocking edge 43 is set to be arc-shaped, and the clearance notch 461 matches the shape of the blocking edge 43. When the fresh air module is not started, the fresh air inlet is closed. At this time, the baffle plate 42 moves to close the air outlet of the fresh air pipe joint 46, and the blocking edge 43 is inserted into the clearance notch 461 to reduce the outside air from entering the room through the fresh air module.

[0047] like Figure 2 As shown, the baffle plate 42 is provided with a plurality of diverter holes 421, and the diverter holes 421 are not provided at the joint of the baffle plate 42 and the fresh air pipe joint 46, so that the diverter holes 421 will not affect the air outlet of the closed fresh air pipe joint 46, and can allow indoor air to pass through. The indoor air is divided into multiple paths through the diverter holes 421, so that the indoor air and the fresh air can be better mixed, and the temperature difference between the indoor air and the fresh air is reduced.

[0048] When the fresh air module is started, the fresh air inlet is controlled to open, and the baffle 42 is moved to be opposite to the indoor air inlet 412. Part of the air flowing through the air inlet and the indoor air inlet 412 flows to the area in front of the filter 3 through the side and leeward side of the baffle 42, part of it flows to the area in front of the filter 3 through the windward side of the baffle 42 and the bracket 41, and part of it flows to the area in front of the filter 3 through the diversion hole 421. The indoor air is divided into multiple paths, and flows from different directions to the front of the filter 3 to be preliminarily mixed with the fresh air, which can improve the mixing effect of the indoor air and the fresh air and reduce the temperature difference between the indoor air and the fresh air.

[0049] After the preliminary mixing, the indoor air and the fresh air enter the air mixing chamber 2 after passing through the filter 3, and are mixed again during the flow, and then supplied to the room through the air outlet pipe 6 and the air outlet hole. After the fresh air and the indoor air are mixed twice, the mixing is more uniform, so that the temperature difference between the fresh air and the indoor air is reduced, and the mixed fresh air has less impact on the indoor temperature and humidity after being supplied to the room, which can improve the comfort of users.

[0050] like Figure 1 and Figure 5As shown, further, the air outlet pipe 6 is provided with at least one air outlet, and the fresh air module further includes an adjustment mechanism for changing the air volume of the air outlet, and when the number of air outlets is set to be multiple, the air outlets can be arranged in the same direction or in different directions. By dividing the mixed fresh air into multiple paths for supplying into the room, the fresh air supply area can be increased, and the mixed fresh air can be blown into the room more gently, thereby improving the comfort of the user.

[0051] In this embodiment, the number of air outlets of the air outlet duct 6 is set to two, and they face opposite directions. The air inlet of the air outlet duct 6 is located in the middle position of the air outlet duct 6, and the air outlet holes on the shell are also set to two. Preferably, one air hole is located at the front of the shell, and the other is located at the rear of the shell. The air outlets are connected to each other one by one, so that fresh air can be blown into the room at the front and rear of the fresh air air conditioner.

[0052] like Figure 1 and Figure 5 As shown, the adjustment mechanism includes an adjustment plate 71, a rotating shaft 73 and an adjustment motor 72. The adjustment motor 72 is installed outside the air outlet 6, and the output shaft of the adjustment motor 72 is coaxially connected to the rotating shaft 73. The end of the rotating shaft 73 away from the adjustment motor 72 extends into the air outlet 6 and is rotatably connected to the air outlet 6, and the rotating shaft 73 is located between the two air outlets. The top of the adjustment plate 71 is fixed on the rotating shaft 73. The rotating shaft 73 can be driven to rotate by the adjustment motor 72, thereby driving the adjustment plate 71 to rotate in the air outlet 6, so that the adjustment plate 71 changes the connection area between the air inlet pipe and the two air outlets, thereby changing the air volume of the two air outlets. Users can adjust the air volume of the two air outlets according to their own needs. For example, in front of the fresh air air conditioner, the user can control the adjustment plate 71 to rotate to reduce the connection area between the air outlet and the air outlet facing the user, thereby reducing the air volume of the mixed fresh air, thereby reducing the discomfort caused by the fresh air, and meeting the needs of users in different situations.

[0053] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
