When the air supply fan is set as a cross-flow fan, the impeller is cylindrical, and the air flow passing through the fan enters the impeller from the blade grid on one side of the rotor and then passes through the inside of the impeller, and is discharged through the other side of the rotor for the second time, so that the direction of the air flow is always perpendicular to the axis of the rotor. The inlet and outlet air flow organization is uniform in a larger air supply and return plane, high efficiency is maintained under the condition of low power, noise is low, and referring to fig. 2, the existing double-through-flow cabinet machine has high wind speed at two sides and low wind speed in the middle; and/or, the speed of the cross flow wind wheel is different along the circular arc position of the cross flow wind wheel, the speed is the highest at the position which is approximately 1/3 of the position outside the cross flow wind wheel, in the prior art, the position corresponds to the handle of the filter screen and the position of the evaporator flute pipe, so that the air inlet is limited and reduced, and after the air supply quantity of the cross flow fan (namely the model of the fan, including the rotating speed, the number of wind wheel blades, the size and the like of the cross flow fan) is fixed, the area of the air inlet is reduced, and the air supply quantity of the air inlet is not matched with the air supply quantity of the cross flow fan, so that the air flow noise is easy to generate.
In the technical scheme provided by the utility model, the casing component 1 comprises an air inlet grille 11 arranged at the rear side, two air supply inlets are penetrated at the front side of the casing component 1, the two air supply fans 2 are distributed at a left-right upward interval, each air supply fan 2 is used for supplying air flow from an air inlet of the air inlet grille 11 to the corresponding air supply inlet, a first air supply fan 201 which is used for being close to one side of a filter screen handle in the two air supply fans 2 is arranged at the rear side of a second air supply fan 202, and the air inlet end of the first air supply fan 201 is staggered with an input/output pipe of a heat exchanger and the filter screen handle by moving the first air supply fan 201 backwards for a certain distance, so that the air inlet of the first air supply fan 201 is not blocked at the place with the largest air inlet speed of the first air supply fan 201, the air inlet quantity of the air supply fan 2 on the side is ensured, the air inlet quantity of the air supply fan 2 can be matched with the air supply quantity of the air supply fans 2, and abnormal noise, uneven left-right wind speed and uneven wind speed of an air conditioner are avoided.
It should be further noted that, because the air inlet grille 11 is configured as a frame, besides the installation frame, a plurality of air inlets arranged in an array are arranged at the inner side of the installation frame, and the size of the air inlets is directly affected by the size of the air inlet grille 11. Since the first air blower 201 moves backward, the opening of the air inlet grille 11 needs to be appropriately adjusted correspondingly, so as to ensure that the air inlet areas of the left and right air blowers 2 can be kept matched with the air supply amount of the air blowers 2. Because the air supply fan 2 is mounted on the main casing of the air conditioner indoor unit, the mounting position of the air inlet grille 11 is also affected by other restriction factors such as the position of parts, the gravity center and the mounting process, the difference between the distance between the wind wheel of the first air supply fan 2 and one end of the air inlet grille 11 and the distance between the wind wheel of the second air supply fan 2 and the other end of the air inlet grille 11 is controlled to be more than or equal to-60 mm, and less than or equal to 60mm, so that the mounting process can be smoothly performed, and the air supply quantity can be further matched with the air supply quantity of the air supply fan 2.
It should be noted that, since the position of the shielding part (the input/output pipe and the filter screen of the heat exchanger) is not necessarily set on the right side, if the distance value of D2 is smaller than the distance value of D1 when the shielding part is set on the left side, the above effect can be achieved when the difference between D2 and D1 is controlled to be equal to or greater than-60 mm. Because the two air supply fans are staggered in the front-back direction, the difference value of D2-D1 does not comprise a scheme equal to 0.
It can be appreciated that the moving distance of the first air supply fan 201 is not limited, when the air supply fan is set as another type of fan, the maximum air supply amount of the air supply fan may be located at another position, and accordingly, the air supply fan and the shielding part may be staggered to a proper position, so that the area with the maximum air supply speed of the type of fan is not shielded.
It will be appreciated that in the present utility model, the front side of the air conditioner is generally understood to be the side facing the user, the rear side is understood to be the side facing away from the user, the left side is the side of the user facing the left hand of the air conditioner, and the right side is the side of the user facing the right hand of the air conditioner.
Specifically, the size of the wind wheel diameter of the model of the air supply fan 2 is generally selected to be 100mm, because the air on the outer periphery sides of the volute and the volute tongue of the air supply fan 2 can be driven into the wind wheel of the air supply fan 2, in order to ensure that the wind wheel of the second air supply fan 2 and the wind wheel of the first air supply fan 2 can fully drive the air on the periphery sides, please refer to fig. 3 to 6, in the embodiment, D1 is less than or equal to 100mm; and/or D2 is less than or equal to 100mm. It should be noted that, the front side of the wind wheel axis of the air supply fan 2 that the tip of the air inlet grille 11 can be located is set up, also the rear side of the axis of the wind wheel of the air supply fan 2 that can be located is set up, so, after the angle and the reasonable setting of aperture of the volute tongue of the air supply fan 2, in the above-mentioned scope, guarantee that the wind wheel of the air supply fan 2 not only can be with the air that is located rear side and side entering into the wind wheel fully, but also can guarantee that the air that is located the front side of the wind wheel center enters into the wind wheel.
It can be understood that the ranges of D1 and D2 are not larger, and when the values of D1 and D2 are too large, the front side edge of the air inlet grille 11 is too far from the vortex center of the air supply fan 2, so that the air inlet of the air supply fan 2 is not affected, and the manufacturing cost and the production and assembly difficulty are increased.
Preferably, the wind wheel diameter of the air supply fan 2 is generally selected to be 100mm, and D1 and D2 are set to be 50mm or less, so that the requirements of the actual air inlet quantity and the actual air inlet angle can be met, and the manufacturing cost of the air inlet grille 11 is low.
