Air enters the shell through the air inlet at the lower part, sequentially flows through the air channel of the centrifugal fan and the heat exchanger and then is sent out from the air outlet at the upper part. Therefore, the air flow is longer in flowing distance from the air inlet to the air outlet, the air pressure loss is serious, the energy consumption is high, the output capacity of the fan is weakened, the air supply distance is short, the air inlet angle and the air outlet angle are limited, only one-side air inlet and one-side air outlet can be realized, the operation efficiency of the whole machine is greatly reduced, the indoor temperature cannot be quickly adjusted, and the user experience is influenced.
The existing evaporative humidifier for the air conditioner is provided with a humidification module and a fan which are independent, and the air supply distance of the humid air depends on the fan of the humidification module.

In addition, the existing evaporative humidifier for air conditioner adopts the principle that air passes through the wet evaporation core to achieve the purpose of humidifying the air. However, depending on the user's usage scenario, the humidifier is often used in winter, and the air temperature and water temperature in winter are low, which results in a small evaporation amount, i.e., a small humidification amount.

The air outlet 3 is positioned on the shell 1 corresponding to the air outlet cavity 12.
A plurality of air outlets 3 are arranged on the casing 1 corresponding to the air outlet chamber 12, each air outlet 3 is a long strip-shaped air outlet 12 extending in the vertical direction, the lower end of each air outlet 12 extends to the first separator 6, the upper end of each air outlet extends to the end of the casing 1, and the end of the air outlet in this embodiment is the top-top cover 9 of the casing 1.
The air outlet 12 is provided with an air deflector 31 and an air deflector driving mechanism, and the air deflector driving mechanism drives the air deflector 31 to close or open the air outlet 12, or adjusts the opening angle of the air deflector 31, or adjusts the air deflector 31 to be in a dynamic rotation state.
The fan assembly comprises a first fan 51 and at least two crossflow fans 52.
The arrangement of the first fan 51 and the cross flow fan 52 will be described in detail below:
the first fan 51 is located in the air inlet chamber 11, and the first fan 51 is used for sending the air in the air inlet chamber 11 into the air outlet chamber 12.
The air outlet of the first fan 51 is connected with the through hole 61 of the first partition 6, and the air inlet of the first fan 51 is positioned in the air inlet chamber 11 to send the air in the air inlet chamber 11 to the air outlet chamber 12.
The first fan 51 of this embodiment is a centrifugal fan, which is mounted on the base 7 and/or the first partition 6 by a fan mount. The centrifugal fan is positioned in the space enclosed by the heat exchanger 4, and the air outlet of the centrifugal fan is directly connected with the through hole 61. Therefore, when the centrifugal fan operates, air in the air inlet cavity 11 is conveyed to the air outlet cavity 12 by the centrifugal fan, air outside the shell 1 enters the air inlet cavity 11 through the 360-degree air inlet 2 and is conveyed to the air outlet cavity 12 through the centrifugal fan after passing through the cylindrical heat exchanger 4, 360-degree dead-angle-free air inlet is realized, and the heat exchanger 4 can efficiently, fully and uniformly exchange heat.
Of course, the first fan 51 may be an axial fan.
At least two crossflow blowers 52 are located within the outlet chamber 12.
The cross flow fans 52 are used for discharging air in the air outlet cavity 12 through the air outlets 3, and each cross flow fan 52 at least corresponds to one air outlet 3. One end of the crossflow blower 52 is mounted on the first partition 6, and the other end of the crossflow blower 52 is mounted on the end of the casing 1, which in this embodiment is the top-top cover 9 of the casing 1.
Specifically, in this embodiment, 4 cross-flow fans 52 are provided, four cross-flow fans 52 are distributed in parallel in the air outlet cavity 12, the rotating shafts of the four cross-flow fans 52 are distributed in the up-down direction, and the four cross-flow fans 52 are uniformly distributed in the air outlet cavity 12.
In this embodiment, four air outlets 3 are provided, each air outlet 3 corresponds to one cross flow fan 52, and when the cross flow fan 52 rotates, the air in the air outlet cavity 12 is sent out of the casing 1 through the air outlet 3.
The four air outlets 3 are evenly distributed on the shell 1.
Of course, each cross-flow fan 52 may correspond to a plurality of outlets 3.
Because the wind speed is gradually reduced in the direction away from the through hole 61 of the first partition 6 in the wind outlet chamber 12, a guide plate 121 for guiding the airflow entering the wind outlet chamber 12 from the through hole 61 is arranged between the first partition 6 and the end portion of the casing 1 and the top cover 9, and a cross flow fan inlet 521 is formed between adjacent guide plates 121.
The cross-flow fan inlet 521 is also a strip shape distributed in the up-down direction, and preferably, the cross-flow fan inlet 521 is parallel to the outlet 3.
The arrangement of the guide plate 121 can improve the uniformity of air inlet of the air inlet 521 of the cross-flow fan, so that the uniformity of air outlet of the air outlet 3 is improved.
In order to avoid the mutual interference of the air flows generated by the cross-flow fans 52 when the cross-flow fans 52 operate simultaneously, and the turbulence and the noise are caused, a second partition 10 is arranged between two adjacent cross-flow fans 52, the second partition 10 is a partition plate and is also arranged in the vertical direction, and the second partition 10 is connected with the side part of the shell 1, the end part-top cover 9, the first partition 6 and the guide plate 121.
Preferably, the second partition 10 is connected to the middle of the baffle 121.
Therefore, the second separator 10, the guide plate 121 and the side of the housing 1 form an air duct of the cross flow fan 52, each cross flow fan 52 has an independent air duct, and when the cross flow fans 52 work simultaneously, the cross flow fans do not interfere with each other, independent air outlet is formed, and turbulence and noise can be reduced.
The air conditioner of the embodiment further comprises a control module, wherein the control module is used for controlling the rotating speed of the first fan 51 and the cross-flow fan 52 to keep the interior of the air outlet cavity 12 in a positive pressure state, so that on one hand, the air supply distance is increased, the room temperature change speed in the refrigeration or heating process is increased, and the user experience is improved; on the other hand, the pressure difference between the air inlet side and the air outlet side of the cross-flow fan 52 is reduced, and the noise can be reduced.
The control module stores the minimum ratio of the rotational speed of the crossflow blower 52 to the rotational speed of the first blower 51 that maintains the positive pressure in the outlet chamber 12. The control module first determines the rotational speed of the crossflow blower 52 from the set gear and determines the rotational speed of the first blower 51 from the rotational speed of the crossflow blower 52 and the minimum ratio.
