[0021] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figures 1 to 3 As shown, the fresh air air conditioner in the utility model includes a casing 1, a fan 2, a main air inlet module and a fresh air inlet module respectively connected to the fan 2, the casing 1 is provided with an air outlet module, the main air inlet module includes a main air inlet 3 arranged on the casing 1 and an evaporator 4 arranged in the casing 1, the main air inlet 3 is connected to the indoor environment and the air outlet module; the fresh air inlet module includes at least one fresh air inlet 5. For the convenience of description, one fresh air inlet 5 is taken as an example in this embodiment, the fresh air inlet 5 is connected to the outdoor environment through an air inlet pipe 8, and is connected to the air outlet module via the fan 2, and the fresh air inlet 5 and the main air inlet 3 are both openable and closable structures.

[0023] By adopting the above scheme, when the user chooses to open only the main air inlet 3, the air circulates internally. At this time, the fresh air air conditioner is used as an ordinary air conditioner. The indoor air enters the shell under the action of the fan 2 and is temperature-adjusted through the evaporator 4. The regulated air is blown out through the air outlet module to achieve the effect of quickly adjusting the indoor temperature; when the user chooses to open the main air inlet 3 and the fresh air inlet 5 at the same time, the internal air circulation and the external air circulation are carried out at the same time, and the indoor air is ventilated while the heating or cooling temperature adjustment work is carried out, so as to provide fresh air to the user while improving the indoor temperature. At this time, the main air inlet 3 and the fresh air inlet 5 share a set of fans 2, and there is only one set of motors to drive the fan 2 to operate, which reduces the overall size of the fresh air air conditioner, simplifies the internal structure of the fresh air air conditioner, and saves the production cost of the whole machine. At the same time, since there is no need to use two sets of air duct systems, the noise during the operation of the fresh air air conditioner is greatly improved, which effectively improves the user's experience.

[0024] like Figure 3As shown, according to another embodiment of the utility model, an air inlet grille 6 is provided at the main air inlet 3, and the evaporator 4 is installed between the air inlet grille 6 and the fan 2. The air inlet grille 6 is conducive to making the indoor air intake more uniform, and the air inlet grille 6 is detachably installed on the main air inlet 3 by buckles or bolts, so as to facilitate disassembly and cleaning. The evaporator 4 is installed on the side of the air inlet grille 6 close to the fan 2, so that the indoor air can quickly contact the evaporator 4 for temperature adjustment after entering from the air inlet grille 6 under the action of the fan 2, and at the same time, the evaporator 4 and the fresh air inlet 5 do not interfere with each other, so as to avoid the reaction between the outdoor air and the evaporator 4 to reduce the temperature adjustment efficiency.

[0025] Furthermore, the air inlet grille 6 includes a plurality of swing blades, which are rotatably connected to the casing 1 via a shaft-like structure. The motor and gear transmission structure are also used to drive the swing blades to rotate to control the opening and closing of the main air inlet 3. The plurality of swing blades are parallel to each other and have uniform spacing.

[0026] like Figure 3 As shown, according to another embodiment of the utility model, the fresh air inlet module also includes a fresh air damper 7, which is arranged at the fresh air inlet 5 and is used to control the opening and closing of the fresh air inlet 5. Specifically, the fresh air damper 7 is a solenoid valve, which can be remotely sensed and controlled to open and close by a remote controller.

[0027] like Figure 1 and Figure 2 As shown, according to another embodiment of the utility model, the air outlet module includes a main air outlet 11 and a damper plate 13 for covering the main air outlet 11, and the damper plate 13 is movably connected to the housing 1. The damper plate 13 closes the main air outlet 11 when the fresh air air conditioner is not in use, so as to prevent the internal structure of the housing 1 from being exposed to the air for a long time and accumulating dust, which affects the user experience. Specifically, the damper plate 13 can be connected to the housing 1 by sliding or rotating to control the opening and closing of the air outlet. When the sliding connection is adopted, a slide groove structure is provided on both sides of the main air outlet 11, and both sides of the damper plate 13 slide with the slide groove structure, and the motor and gear transmission structure are used to drive the sliding door to slide and the damper plate 13 is rolled up to control the opening and closing of the main air outlet 11; when the rotation connection is adopted, the damper plate 13 is connected to the housing 1 by a rotating shaft structure, and the motor and gear transmission structure are also used to drive the damper plate 13 to rotate to control the opening and closing of the main air outlet 11.

[0028] like Figure 3As shown, according to another embodiment of the utility model, the air outlet module also includes a fresh air outlet 12 arranged below the main air outlet 11, the fan 2 is divided into an upper and lower part, and the air inlet end and the air outlet end of the lower part of the fan 2 are respectively horizontally provided with an air inlet channel 9 and an air outlet channel 10, the main air inlet 3 is connected with the main air outlet 11 through the upper part of the fan 2, and the fresh air inlet 5 is connected with the fresh air outlet 12 via the air inlet channel 9, the lower part of the fan 2, and the air outlet duct. The fresh air outlet 12 is arranged opposite to the fresh air inlet 5, and the main air outlet 11 is arranged opposite to the main air inlet 3.

[0029] As in the present embodiment, when the fresh air inlet 5 and the main air inlet 3 are opened at the same time, the swing blades can be controlled by the motor to rotate to the horizontal direction to guide the air entering the casing 1, so that the indoor air enters the casing 1 horizontally and is blown out after the temperature is adjusted by the evaporator 4. Since the air inlet channel 9 and the air outlet channel 10 are arranged horizontally, the two guide the outdoor air and the outdoor air can be blown into the room horizontally. In this way, the interference between the internal air circulation and the external air circulation is avoided, and the fresh air outlet 12 is arranged below the main air outlet 11 to avoid blowing directly onto the user's face, which is conducive to improving the user experience.

[0030] like Figure 1 and Figure 2 As shown, further, the main air inlet 3 and the fresh air inlet 5 are arranged on the same side, the main air outlet 11 and the fresh air outlet 12 are arranged on the same side, and the damper plate 13 can cover the main air outlet 11 and the fresh air outlet 12 at the same time, and there is no need to set a damper plate 13 for the fresh air outlet 12 separately, which is beneficial to improving the aesthetic appearance of the fresh air air conditioner.

[0031] like Figure 3 As shown, according to another embodiment of the utility model, the fresh air intake module also includes an air filter (not shown in the figure) arranged in the air intake channel 9, and the air filter can filter out impurities in the air to prevent the impurities from entering the interior of the casing 1.
