Referring to fig. 1 to 7, the air conditioner indoor unit 100 of the air conditioner indoor unit 100 includes a casing assembly 1 and two air supply fans 2, wherein the casing assembly 1 is provided with an air inlet and two air supply openings; the two air supply fans 2 are installed in the shell assembly 1, each air supply fan 2 comprises an air channel shell 6 and a volute tongue 5, an air channel is defined between the air channel shell 6 and the volute tongue 5 and is used for supplying air flow from the air inlet to the corresponding air supply opening, each volute tongue 5 comprises an air outlet guide section 7 used for forming a fan air outlet of the air supply fan 2, and the two air supply fans 2 comprise a first air supply fan 21 and a second air supply fan 22; the included angle between the air outlet guide section 7 of the volute tongue 5 of the first air supply fan 21 and the central line of the casing assembly 1 along the front-back direction is I, and the included angle between the air outlet guide section 7 of the volute tongue 5 of the second air supply fan 22 and the central line of the casing assembly 1 along the front-back direction is X-44 degrees < I-X < 44 degrees.

According to the technical scheme provided by the utility model, the air inlet quantity difference between the first air supply fan 21 and the second air supply fan 22 is reduced by changing the relation between the included angle between the air outlet guide section 7 of the volute tongue 5 of the first air supply fan 21 and the central line of the casing assembly 1 along the front-back direction and the included angle between the air outlet guide section 7 of the volute tongue 5 of the second air supply fan 22 and the central line of the casing assembly 1 along the front-back direction, so that the problem of uneven air outlet left and right of the existing air conditioner with the double air supply fans 2 is weakened.

It should be noted that, the greater the included angle between the air outlet guide section 7 of the volute tongue 5 and the central line of the casing assembly 1 along the front-back direction, the greater the distance between the air channel casing 6 and the indoor heat exchanger 4 can be correspondingly achieved, and air intake is more facilitated, so that the air intake of the first air supply fan 21 and the second air supply fan 22 can be adjusted by adjusting the values of I and X, the difference of the air intake between the first air supply fan 21 and the second air supply fan 22 is reduced, and the problem of uneven air outlet of the air conditioner of the existing double air supply fans 2 is weakened.

It should be noted that, because 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 shielding part is set on the left side, that is, near the second air blower 22, X is greater than I, that is, -44 ° < I-X < 0 °, at this time, the air intake of the second air blower 22 is increased, the air intake of the first air blower 21 is decreased, and the difference between the air intakes of the first air blower 21 and the second air blower 22 is reduced.

If the shielding part is arranged on the right side, that is, near the first air supply fan 21, I is greater than X, that is, 0 ° < I-X < 44 °, at this time, the air intake of the first air supply fan 21 is increased, the air intake of the second air supply fan 22 is decreased, and the difference between the air intake of the first air supply fan 21 and the air intake of the second air supply fan 22 is reduced.

Of course, the difference between I and X cannot be too large, but, once the difference exceeds 44 °, X must be set to be relatively small, and at this time, the air intake of the second air blower 22 is limited to a great extent, so that the energy efficiency of the second air blower 22 is affected.

Further, the included angle between the air outlet guiding section 7 of the volute tongue 5 and the central line of the casing assembly 1 along the front-back direction cannot be too large, because the position of the air outlet is fixed, and the air flows along the volute tongue 5, so that the too large angle of the volute tongue 5 can cause large turning angle and large air loss, while the included angle between the air outlet guiding section 7 of the volute tongue 5 and the central line of the casing assembly 1 along the front-back direction cannot be too small, which would affect the distance between the air duct casing 6 and the indoor heat exchanger 4 correspondingly, thereby affecting the air inlet of the air supply fan 2, therefore, 30 ° < I < 80 °, and/or 30 ° < X < 80 °, thereby ensuring that the air inlet of the first air supply fan 21 and the second air supply fan 22 is not too small, and avoiding the too large angle from causing too large air loss, thereby ensuring the energy efficiency of the first air supply fan 21 and/or the second air supply fan 22.

It is understood that the two technical schemes of 30 degrees < I < 80 degrees and 30 degrees < X < 80 degrees can be alternatively arranged or can be arranged at both sides, and the method is not limited in this regard.

Furthermore, in order to ensure that the air inlet quantity of the two air supply fans 2 can meet the energy efficiency requirement, 60 degrees is less than I, and/or 60 degrees is less than X, the arrangement can avoid the problem that the air inlet quantity is influenced due to the fact that the included angle between the air outlet guide section 7 of the volute tongue 5 and the central line of the casing assembly 1 along the front-back direction is too small, therefore, 60 degrees is less than I and 80 degrees, and/or 60 degrees is less than X and less than 80 degrees, and the air inlet quantity of the two air supply fans 2 can meet the energy efficiency requirement.

In the present embodiment, I is 74 ° and X is 60 °, so that the provision of I as 74 ° can ensure the maximum air intake of the first air blower 21, ensure energy efficiency thereof, and eliminate the gap between the air intake of the second air blower 22, while X as 60 ° can make the second air blower 22 face the air outlet while taking into consideration energy efficiency thereof.

Further, the difference between I and X cannot be too large, or I and X cannot be made large at the same time, and-15 ° < I-X < 15 °, so that I and X can be designed relatively large at the same time, and the energy efficiency of both the first air blower 21 and the second air blower 22 is considered.

Still further, in the left-right direction, the air outlet directions of the two air supply fans 2 are arranged away from each other, so that the mutual interference of the air outlets of the two cross-flow wind wheels is avoided.

The casing assembly 1 comprises an air inlet grille 11, the air inlet grille 11 is provided with an air inlet, the air inlet grille 11 is arranged on the periphery of the two air supply fans 2 in a surrounding mode, the air inlet grille 11 is provided with a first end portion and a second end portion which correspond to the first air supply fan 21 and the second air supply fan 22, the distance between the first end portion and the wind wheel axis of the first air supply fan 21 is D1 in the front-back direction, and the distance between the second end portion and the wind wheel axis of the second air supply fan 22 is D2, wherein D1-D2 is less than or equal to 10mm and less than or equal to 60mm.

The main feature of the blower fan 2 is that the impeller is cylindrical, the air flow passing through the fan enters the impeller from the blade grid on one side of the rotor, then passes through the inside of the impeller, and is discharged through the other side of the rotor for the second time, and 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 still maintained under the condition of low power, noise is low, referring to fig. 2, the existing double-cross-flow cabinet machine is high in air speed at two sides and low in air speed in the middle, the air speeds of the cross-flow wind wheels are different along the circular arc positions of the cross-flow wind wheels, the speeds are different, the air speeds are highest at about 1/3 position outside the cross-flow wind wheels, in the prior art, the positions correspond to the positions of a handle of a filter screen and a flute-shaped pipe of an evaporator, so that an air inlet is limited to be reduced, and the air supply quantity (namely the type of the fan, including the rotating speed of the air supply fan 2, the number of wind wheel blades, the size and the like) of the air supply fan 2 is not matched after the area of the air inlet is reduced, so that the air supply fan 2 is easy to generate air flow noise.

Meanwhile, the first air blower 21 is disposed at the rear side of the second air blower 22.

According to the technical scheme provided by the utility model, the shell component 1 comprises the air inlet grille 11 arranged at the rear side end, the front side end of the shell component 1 is provided with two air inlets in a penetrating way, the two air supply fans 2 are distributed at right and left intervals, each air supply fan 2 is used for supplying air flow from the air inlet of the air inlet grille 11 to the corresponding air inlet, one air supply fan 2, which is used for being close to one side of a filter screen handle, of the two air supply fans 2 is arranged at the rear side of the other air supply fan 2, the air inlet end of the air supply fan 2 is staggered with the input and output pipe and the filter screen handle of the heat exchanger by moving the air supply fan 2, and the place with the largest air inlet speed of the air supply fan 2 is not blocked, so that the air inlet quantity of the air supply fan 2 at the side can be matched with the air inlet quantity of the air supply fan 2, and abnormal noise, howling and uneven left and right wind speeds of the air conditioner 100 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. After the air supply fan 2 moves backwards, the opening of the air inlet grille 11 needs to be appropriately adjusted correspondingly, so that the air inlet area of the left air supply fan 2 and the air inlet area of the right air supply fan 2 can be ensured to be matched with the air supply amount of the air supply fan 2. Because the air supply fan 2 is mounted on the main casing 12 of the air conditioner indoor unit 100, the mounting position of the air supply grille 11 is also affected by other restriction factors such as the position of parts, the center of gravity, the mounting process and the like, when the difference between the distance between the wind wheel of the air supply fan 2 and one end of the air supply grille 11, which is positioned at the rear side, and the distance between the wind wheel of the air supply fan 2 and one end of the air supply grille 11, which is positioned at the front side, is controlled to be less than or equal to 60mm, the smooth progress of the mounting process can be ensured, and the air supply quantity can be further ensured to be 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.

In this embodiment, each air supply fan includes an air duct housing 6 and a wind wheel, where the air duct housing 6 is formed with an air duct, and the wind wheel is disposed at an air inlet end of the air duct and is used for delivering air flow from the air inlet to the corresponding air supply port; in the front-rear direction, the wind wheel of the first air supply fan 21 is located at the rear side of the wind wheel of the second air supply fan 22, and the two air duct shells 6 are asymmetrically arranged with respect to the central line of the casing assembly 1. Because the noise amount of the air blower 2, the air blowing effect and other technical index parameters are related to the position of the wind wheel, the shape of the air duct enclosed by the air duct shells 6 and the like, in order to ensure the normal air blowing effect of each air blower 2, the two air duct shells 6 are asymmetrically arranged relative to the central line of the shell assembly 1, so that each air duct shell 6 can be matched with the corresponding position of the wind wheel.

It will be appreciated that the moving distance of the first air supply fan 21 is not limited, and 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.

The distance between the central axes of the wind wheels of the two air supply fans 2 is H, wherein H is more than 0 and less than 60mm.

It will be appreciated that in the present utility model, the front side of the air conditioner 100 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 facing the left hand of the user when facing the air conditioner 100, and the left side is the side facing the right hand of the user when facing the air conditioner 100.

Specifically, the size of the wind wheel diameter of the model of the air blower 2 is generally selected to be 100mm, and because the air on the outer periphery sides of the volute and the volute tongue 5 of the air blower 2 will be driven into the wind wheel of the air blower 2, in order to ensure that the wind wheel of the air blower 2 on the front side and the wind wheel of the air blower 2 on the rear side can both be ensured, please refer to fig. 3 and 4, in this embodiment, D1 is less than or equal to 100mm, and 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 5 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 wind wheel center front side 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.

Further, in order to ensure the aesthetic property and manufacturability of the air inlet grille 11, in this embodiment, the air inlet grille 11 is symmetrically disposed along a symmetry axis extending in the front-rear direction, so that the air inlet grille 11 has an axisymmetric appearance, which not only meets the general aesthetic property of the public, but also is convenient in manufacturing and demolding.

Specifically, in this embodiment, the housing assembly 1 further includes a housing 12, a mounting opening is formed at a rear end of the housing 12, the air inlet grille 11 is integrally formed and disposed, and the air inlet grille 11 is covered on the mounting opening. So, need not to correspond two air supply fans 2 set up different air inlet grids 11 respectively, only need set up one air inlet grid 11 of installation for air intake on the air inlet grid 11 simultaneously can with the air inlet end intercommunication of two air supply fans 2, so set up, the installation of being convenient for.

Specifically, in order to enable the user to feel that the air volume and the air speed of the two air blowing openings are identical when using the air conditioner, in the present embodiment, the air blowing amounts of the two air blowing fans 2 are equivalent. It should be noted that, the air volume of the two air-supplying fans 2 is related to parameters such as the number of wind blades, the diameter of the wind wheel, the sizes of the air inlet and the air outlet formed by enclosing the volute and the volute tongue 5, and the angles of the air inlet and the air outlet, so that the utility model is not particularly limited to the specific parameters such as the number of wind blades of the two air-supplying fans 2, the diameter of the wind wheel, the sizes of the air inlet and the air outlet formed by enclosing the volute and the volute tongue 5, and the angles of the air inlet and the air outlet, so long as the air volume of the two air-supplying fans 2 is finally the same or the energy efficiency of the air supply is basically consistent.

In this way, the air supply amounts of the two air supply fans 2 are set to be equivalent, when other related components are arranged, the components with the same model can be adopted, or after the related parameter of one air supply fan 2 is calculated, the other air supply fan 2 can refer to and refer to the related parameter.

Further, in order to form a localized air inlet flow at the air inlet ends of the two air supply fans 2, in this embodiment, an air duct is formed in each air supply fan 2, and the air duct has an inner air inlet and an inner air outlet; two air passing areas are formed on the air inlet grille 11, each air passing area is correspondingly arranged with an inner air inlet of the air duct, and the air passing areas of the two air passing areas are equivalent. Thus, when the areas of the two air passing areas are basically equal, the air quantity flowing to the air inlet ends of the two air supply fans 2 is basically consistent.

In order to make the areas of the two air passing areas equal, the sizes, the numbers and the positions of the air inlet holes on the air inlet grille 11 corresponding to the air inlet ends of the air supply fans 2 may be set, so that the total area of the air inlet holes of the air inlet grille 11 is consistent with the total area of the air inlet holes of the other part.
