[0014] Optionally, the first air outlet grille includes a plurality of first vertical ribs spaced along a first direction, and the first vertical ribs have a width in the first direction;

[0015] The second air outlet grille includes a plurality of second vertical ribs spaced along a second direction; the second vertical ribs have a width in the second direction;

[0016] The interval between two adjacent first vertical ribs is smaller than the interval between two adjacent second vertical ribs, and the width of the first vertical rib is greater than the width of the second vertical rib.

[0017] Optionally, the ratio of the interval between two adjacent second vertical ribs to the interval between two adjacent first vertical ribs is less than or equal to 8.

[0018] Optionally, the interval between two adjacent first vertical ribs is less than or equal to 15 mm, and / or the interval between two adjacent second vertical ribs is less than or equal to 15 mm.

Here, the present disclosure sets the effective air outlet area of the first air outlet grille to be smaller than the effective air outlet area of the second air outlet grille, so that the air outlet resistance of the first air outlet grille is greater than that of the first air outlet grille. And because the air volume flowing to the first air outlet channel is greater than the air volume flowing to the second air outlet channel, such a setting can balance the air volume flowing out of the first air outlet channel and the air volume flowing out of the second air outlet channel, that is, shorten or even eliminate the difference between the air volume flowing out of the first air outlet channel and the air volume flowing out of the second air outlet channel. Thus, the uniformity of the air outlet of the two air outlet channels in the indoor unit can be improved.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The following will describe in detail the specific implementation of the present disclosure with reference to the drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure and is not used to limit the present disclosure.

[0033] In the present disclosure, unless otherwise specified, the orientation terms such as "front, back, left, right" are based on Figure 1Defined by the XY coordinate system therein. Specifically, the X direction refers to the left - right direction, with the side pointed by the arrow being the left and the opposite side being the right. The Y direction refers to the front - back direction, with the side pointed by the arrow being the front and the opposite side being the back. The up - down direction can correspond to the gravity direction of the flow - dividing member and the indoor unit. "Inside and outside" refer to the inside and outside of the contour of each component part. "Upstream and downstream" are defined based on the flow direction of the air flow. The terms "first and second" used are for distinguishing one element from another and do not have sequentiality or importance. In addition, in the following description when referring to the attached drawings, the same reference numerals in different drawings represent the same or similar elements, and the present disclosure will not elaborate on this.

[0034] According to some embodiments of the present disclosure, there is provided an indoor unit. Referring to Figure 1 and Figure 2 shown in, the indoor unit includes: an air duct structure 1 having an air - guiding channel 11 which extends obliquely from the rear to the front and to the left. A cross - flow fan 4 may be provided on the air duct structure 1; an air - outlet structure 2 communicating downstream of the air duct structure 1 and having a first air - outlet channel 21 and a second air - outlet channel 22 provided on the right side of the first air - outlet channel 21; and a flow - dividing member 3 including a first air - outlet grille 31 provided in the first air - outlet channel 21 and a second air - outlet grille 32 provided in the second air - outlet channel 22. The effective air - outlet area of the first air - outlet grille 31 is smaller than that of the second air - outlet grille 32.

[0035] Through the above - mentioned technical solution, in the indoor unit provided by the present disclosure, the air flow in the air - guiding channel 11 can enter the first air - outlet channel 21 through the first air - outlet grille 31 and enter the second air - outlet channel 22 through the second air - outlet grille 32. Among them, since the air - guiding channel 11 extends obliquely from the rear to the front and to the left, the air volume flowing to the first air - outlet channel 21 is greater than the air volume flowing to the second air - outlet channel 22. Here, the present disclosure sets the effective air - outlet area of the first air - outlet grille 31 to be smaller than that of the second air - outlet grille 32, so that the air - outlet resistance of the first air - outlet grille 31 is greater than that of the first air - outlet grille 31. And because the air volume flowing to the first air - outlet channel 21 is greater than the air volume flowing to the second air - outlet channel 22, such a setting can balance the air volume flowing out of the first air - outlet channel 21 and the air volume flowing out of the second air - outlet channel 22, that is, shorten or even eliminate the difference between the air volume flowing out of the first air - outlet channel 21 and the air volume flowing out of the second air - outlet channel 22. Thus, the uniformity of the air flow from the two air - outlet channels in the indoor unit can be improved.

[0036] It should be noted that referring to Figure 1 and Figure 2As shown in the figure, the effective air outlet area of the first air outlet grille 31 can be understood as follows: the first air outlet grille 31 may have a first air outlet surface 310 perpendicular to its own air inlet direction, and the effective air outlet area is the area of the first air outlet surface 310 minus the area projected by the solid part of the first air outlet grille 31. Similarly, the effective air outlet area of the second air outlet grille 32 can be understood as follows: the second air outlet grille 32 may have a second air outlet surface 320 perpendicular to its own air inlet direction, and the effective air outlet area is the area of the second air outlet surface 320 minus the area projected by the solid part of the second air outlet grille 32. Among them, the area of the first air outlet surface 310 may be equal to the area of the second air outlet surface 320.

[0037] In some embodiments of the present disclosure, referring to Figure 2 As shown in the figure, the first air outlet grille 31 may include a plurality of first vertical ribs 311 spaced along a first direction, and the first vertical ribs 311 have a width in the first direction; the second air outlet grille 32 includes a plurality of second vertical ribs 321 spaced along a second direction; the second vertical ribs 321 have a width in the second direction; the interval between two adjacent first vertical ribs 311 may be smaller than the interval between two adjacent second vertical ribs 321, and the width of the first vertical ribs 311 may be equal to the width of the second vertical ribs 321. In this way, by reducing the projected area of the virtual part of the first air outlet grille 31 on the first air outlet surface 310, the effective air outlet area of the first air outlet grille 31 can be reduced, so as to achieve that the effective air outlet area of the first air outlet grille 31 is smaller than the effective air outlet area of the second air outlet grille 32. Here, it should be noted that when the width of the first vertical ribs 311 changes in the direction from the rear to the front, the interval between two adjacent first vertical ribs 311 can be understood as the maximum interval between two adjacent first vertical ribs 311. Similarly, when the width of the second vertical ribs 321 changes in the direction from the rear to the front, the interval between two adjacent second vertical ribs 321 can be understood as the maximum interval between two adjacent second vertical ribs 321.

[0038] In other embodiments of the present disclosure, referring to Figure 2 As shown in the figure, the interval between two adjacent first vertical ribs 311 may be equal to the interval between two adjacent second vertical ribs 321, and the width of the first vertical ribs 311 may be greater than the width of the second vertical ribs 321. In this way, by increasing the projected area of the solid part of the first air outlet grille 31 on the first air outlet surface 310, the effective air outlet area of the first air outlet grille 31 can also be reduced, so as to achieve that the effective air outlet area of the first air outlet grille 31 is smaller than the effective air outlet area of the second air outlet grille 32.

[0039] In some other embodiments of the present disclosure, the interval between two adjacent first vertical ribs 311 may be smaller than the interval between two adjacent second vertical ribs 321, and the width of the first vertical rib 311 may be greater than the width of the second vertical rib 321. In this way, by reducing the projected area of the virtual part of the first air outlet grille 31 on the first air outlet surface 310 and by increasing the projected area of the solid part of the first air outlet grille 31 on the first air outlet surface 310, the effective air outlet area of the first air outlet grille 31 can also be reduced, so as to achieve that the effective air outlet area of the first air outlet grille 31 is smaller than the effective air outlet area of the second air outlet grille 32.

[0040] In some embodiments of the present disclosure, the ratio of the interval between two adjacent second vertical ribs 321 to the interval between two adjacent first vertical ribs 311 may be less than or equal to 8. In this way, it is avoided that the ratio is too large, resulting in too large air outlet resistance of the first air outlet grille 31 and affecting the air outlet uniformity of the two air outlet channels.

[0041] In some embodiments of the present disclosure, the interval between two adjacent first vertical ribs 311 may be less than or equal to 15 mm, so that the user's fingers or even palm can be prevented from reaching into the first air outlet grille 31, and / or the interval between two adjacent second vertical ribs 321 is less than or equal to 15 mm, so that the user's fingers or even palm can be prevented from reaching into the second air outlet grille 32. Thus, the flow dividing member 3 of the present disclosure can also be configured as a finger protection net.

[0042] In some embodiments of the present disclosure, the first air outlet grille 31 and the second air outlet grille 32 may be integrally formed. In this way, the number of components of the indoor unit can be reduced, and the connection between the first air outlet grille 31 and the second air outlet grille 32 can be omitted.

[0043] In some embodiments of the present disclosure, the flow dividing member 3 and the air outlet structure 2 may be integrally formed. In this way, the number of components of the indoor unit can be reduced, and the connection between the flow dividing member 3 and the air outlet structure 2 can be omitted.

[0044] In some embodiments, referring to Figure 1 as shown in, the air outlet structure 2 may include a flow dividing cone 23 and an air outlet frame 24. The flow dividing cone 23 and the air outlet frame 24 enclose a first air outlet channel 21 and a second air outlet channel 22. The flow dividing cone 23 has a top end 231, and the connection between the first air outlet grille 31 and the second air outlet grille 32 is connected to the top end 231. In this way, the first air outlet grille 31 can be arranged at the air inlet of the first air outlet channel 21, and the second air outlet grille 32 can be arranged at the air inlet of the second air outlet channel 22.

[0045] In some embodiments of the present disclosure, referring to Figure 1 and Figure 2As shown, the first vertical rib 311 extends obliquely forward and leftward from back to front. In this way, the air flow can be guided to the first air outlet channel 21.

[0046] In some embodiments of the present disclosure, with reference to Figure 1 and Figure 2 As shown, the second vertical rib 321 extends obliquely forward and rightward from back to front. In this way, the air flow can be guided to the second air outlet channel 22.

[0047] According to a second aspect of the present disclosure, an air conditioner is provided, including the indoor unit as described above. This air conditioner has all the beneficial effects of the above indoor unit, which will not be elaborated herein.

[0048] The preferred embodiments of the present disclosure have been described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0049] In addition, it should be noted that, in the above specific embodiments, the various specific technical features described can be combined in any suitable manner without conflict. To avoid unnecessary repetition, the present disclosure will not further describe various possible combination methods.

[0050] Furthermore, any combination can be made between various different embodiments of the present disclosure, as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
