Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

In the related art, the cross-flow wind turbine cabinet has only one air outlet for blowing forward, and only one fan assembly and air inlet. The air inlet and outlet of the cross-flow wind turbine cabinet is single, which cannot meet various needs.

The indoor unit 1 of the split floor air conditioner according to the embodiment of the present invention will be described below with reference to FIGS. 1-7 .

The indoor unit 1 of the split floor air conditioner according to the present invention includes a casing 11, a fan assembly 12 and an air intake grille 13, wherein the casing 11 has a plurality of air inlets and a plurality of outlets respectively corresponding to the plurality of air inlets. The air outlet, the fan assembly 12 is arranged in the housing 11, and the fan assembly 12 is suitable for guiding the airflow from the air inlet to the corresponding air outlet; there are multiple air inlet grilles 13 and each air inlet grill 13 is arranged on the corresponding air inlet place.

Multiple air inlets and multiple fan assemblies 12 can be in one-to-one correspondence. When the corresponding fan assemblies 12 are working, the airflow can enter the casing 11 through the corresponding air inlets, and guide the air from the corresponding air inlets to the air outlets. In the related technology, there is only one air outlet of the cabinet machine, which cannot meet some needs of customers. For example, when the room where the cabinet machine is placed has a lot of dust, the side of the air inlet near the ground will enter the air, which will cause the indoor The dust is flying, causing pollution to the indoor environment. Of course, there are many scenarios that cannot be satisfied by a single air inlet, so I won’t go into details here.

Further, in the split floor air conditioner indoor unit 1 according to the present invention, a plurality of air inlet grilles 13 are set corresponding to the air inlets, so as to ensure that each air inlet grill 13 can guide the air flow, and The air grille 13 is suitable to be supported on the outside of each air inlet, which improves the aesthetics of the indoor unit of the split floor air conditioner.

According to the split floor air conditioner indoor unit 1 of the present invention, by setting a plurality of fan assemblies, a plurality of air inlets and a plurality of grilles, the opening and closing of different fan assemblies 12 are controlled, so that the air inlet corresponding to the fan assembly 12 Select the air intake or close, and then meet the needs of users to choose different air inlets for air intake. Each fan assembly 12 is independent of each other and does not interfere with each other. Each air inlet also remains independent of each other and does not interfere with each other. It is necessary to select the corresponding air inlet area, select the air inlet directly facing the air inlet area, and turn on the corresponding fan assembly 12. The control of the indoor unit 1 of the split floor air conditioner is more convenient, and the selection of the air inlet area is more flexible. , a plurality of air intake grilles 13 are arranged on the outside of the corresponding air intakes, ensuring the air intake reliability of the indoor unit 1 of the split floor air conditioner.

According to one embodiment of the present invention, the casing 11 has an upper air passage and a lower air passage, and the casing 11 is formed with an upper air inlet 101a and an upper air outlet 102a respectively connected with the upper air passage and a lower air inlet 101b respectively connected with the lower air passage. and the lower air outlet 102b. The setting of the upper air channel and the lower air channel makes the indoor unit 1 of the split floor air conditioner have two air supply channels arranged and spaced apart in the up and down direction. The upper air channel and the lower air channel can supply air separately, and the split floor air conditioner The indoor unit 1 can conduct the upper air duct or the lower air duct according to the user's selection, so as to realize air supply.

For example, when the user thinks that the air dust corresponding to the lower air inlet 101b in the lower air duct is relatively large, he can choose to close the lower air duct, and the indoor unit 1 of the split floor air conditioner only sends air through the upper air duct; 101b chooses to close the upper air duct and only use the lower air duct for air supply when there may be a direct blow to the upper body of the person, so as to improve the user experience.

According to one embodiment of the present invention, the fan assembly includes an upper fan assembly 121 arranged in the upper air passage and a lower fan assembly 122 arranged in the lower air passage.

The upper duct has a stronger attraction to the airflow, which allows more airflow to enter the fan through the upper duct. Wherein, the air passing density of the upward air grill 131 is smaller than the air passing density of the downward air grill 132, and the grilles in the upward air grill 131 are denser, which can more effectively control the air flow in the upper air duct. The wind pressure of the airflow in the upper air duct is lowered to ensure more uniform air flow from the upper and lower fans, improve the air output effect of the indoor unit 1 of the split floor-standing air conditioner, and improve the user experience.

According to an embodiment of the present invention, the upward air intake grille 131 and the downward air intake grille 132 are integrally formed. Setting the upper inlet grille 131 and the lower inlet grille 132 as an integral molding can reduce the production difficulty of the inlet grille, reduce the number of parts in the indoor unit of the split floor-standing air conditioner, and make the indoor unit of the split floor-standing air conditioner Machine installation is more convenient.
