As an example, referring to fig. 8, the height dimension L of the lower edge of the third opening 111b from the inner bottom surface of the water tray 7 is not less than 100mm, so that the splashing of water in the water tray 7 during the air intake in the first channel 111 can be further reduced. Alternatively, the height dimension L of the lower edge of the third opening 111b from the inner bottom surface of the drip tray 7 may be selected from 100mm, 105mm, 110mm, 115mm, 120mm, or other dimensions.

In an embodiment of the present application, referring to fig. 8, an opening height dimension D of the third opening 111b is not less than 150mm. By the arrangement, the air quantity entering the first channel 111 can be ensured, so that the air supply quantity of the indoor unit of the air conditioner can be improved. Alternatively, the opening height dimension D of the third opening 111b may be selected from 150mm, 155mm, 160mm, 165mm, 170mm, or other dimensions, etc.

In an embodiment of the present application, referring to fig. 2 and 4, the first air supply module 2 includes a centrifugal air duct housing 21 and a double suction centrifugal fan 22 disposed in the centrifugal air duct housing 21, and two air suction sides of the double suction centrifugal fan 22 are respectively formed as a first air inlet side 201 and a second air inlet side 202.

As an example, the centrifugal air duct shell 21 extends up and down, the axial direction of the double-suction centrifugal fan 22 is transversely distributed, at this time, the first air inlet side 201 and the second air inlet side 202 are respectively arranged at two transverse sides of the centrifugal air duct shell 21, and the air outlet side of the centrifugal air duct shell 21 is positioned at the top. Alternatively, the first air inlet side 201 is provided on a side of the centrifugal air duct housing 21 facing the third channel 12, and the second air inlet side 202 is provided on a side of the centrifugal air duct housing 21 facing away from the third channel 12.

In an embodiment of the present application, referring to fig. 2 and 4, the second air supply module 3 includes a through-flow air duct housing and a through-flow fan disposed in the through-flow air duct housing.

As an example, the cross flow fan is installed in a vertical type. Because the diameter of the cross flow fan is far smaller than the height of the cross flow fan, the cross flow fan is vertically installed, the whole width or thickness of the air conditioner indoor unit can be further reduced, the occupied area of the air conditioner indoor unit is further reduced, and the arrangement of the air conditioner indoor unit is facilitated.

In an embodiment of the present application, referring to fig. 1 to 4, the indoor air outlet 103 includes a front air outlet 103a disposed on the front side of the casing 1 and an ejector air outlet 103b disposed on the top of the casing 1, the air outlet side of the first air supply module 2 is communicated with the ejector air outlet 103b, and the air outlet side of the second air supply module 3 is communicated with the front air outlet 103 a.

By arranging the front air outlet 103a and the ejection air outlet 103b, the air supply area is enlarged, the air outlet area is increased, and the efficiency of indoor air conditioning can be further improved. In this embodiment, considering that the second air supply module 3 adopts a cross flow fan, the front air outlet area can be further increased by communicating the second air supply module 3 with the front air outlet 103a, so as to improve the air supply efficiency. The first air supply module 2 is arranged below the second air supply module 3, and the air outlet side of the first air supply module 2 is located at the top of the first air supply module 2, so that the air blown out from the air outlet side of the first air supply module 2 can flow to the position of the ejection air outlet 103b along the direction by communicating the air outlet side of the first air supply module 2 with the ejection air outlet 103b, the air resistance can be reduced, and the air supply efficiency can be further improved.

The utility model also provides an air conditioner which comprises an outdoor unit and an air conditioner indoor unit, wherein the specific structure of the air conditioner indoor unit refers to the embodiment, and as the air conditioner adopts all the technical schemes of all the embodiments, the air conditioner at least has all the beneficial effects brought by the technical schemes of the embodiments, and the detailed description is omitted.

The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the description of the present utility model and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the utility model.
