[0041] The embodiments of the present application are described in detail below, examples of which are shown in the drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0042] As shown in the drawings, Figure 1 the air conditioner of the embodiments of the present application comprises a shell 1, a centrifugal fan 2, a bottom heat exchanger 3, a first heat exchanger 4 and a second heat exchanger 5.

[0043] The shell 1 is provided with a bottom air inlet 11, a first air inlet 12, a second air inlet 13 and an air outlet 14. The bottom air inlet 11 is arranged at the bottom of the shell 1, the first air inlet 12 and the second air inlet 13 are arranged on the side of the shell 1 and are opposite to each other in the length direction of the shell 1, and the air outlet 14 is arranged above the bottom air inlet 11.

[0044] For example, as shown in the drawings, Figure 1 and Figure 2 The shell 1 can be generally cuboid, the length direction of the shell 1 can be the left-right direction, the bottom air inlet 11 can be arranged on the bottom surface of the shell 1, the first air inlet 12 can be arranged on the left side surface of the shell 1, the second air inlet 13 can be arranged on the right side surface of the shell 1, and the air outlet 14 can be arranged on the front side surface of the shell 1 and can be adjacent to the top surface of the shell 1.

[0045] The centrifugal fan 2 is assembled in the shell 1, and the bottom heat exchanger 3 is arranged between the bottom air inlet 11 and the centrifugal fan 2 and is used for heat exchange with the airflow flowing from the bottom air inlet 11. For example, as shown in the drawings, Figure 1 and Figure 2 The centrifugal fan 2 can be fixed in the shell 1, and the bottom heat exchanger 3 can also be installed in the shell 1, and in the up-down direction, the bottom heat exchanger 3 can be located between the centrifugal fan 2 and the bottom air inlet 11.

[0046] The first heat exchanger 4 is arranged between the first air inlet 12 and the centrifugal fan 2 and is used for heat exchange with the airflow flowing from the first air inlet 12, and the second heat exchanger 5 is arranged between the second air inlet 13 and the centrifugal fan 2 and is used for heat exchange with the airflow flowing from the second air inlet 13.

[0047] For example, as shown in Figure 1 The first heat exchanger 4 and the second heat exchanger 5 can be arranged in the shell 1, wherein the first heat exchanger 4 can be arranged at the left side of the centrifugal fan 2, and the second heat exchanger 5 can be arranged at the right side of the centrifugal fan 2.

[0048] When the centrifugal fan 2 is running, the external air can be sucked into the shell 1 through the bottom air inlet 11, the first air inlet 12 and the second air inlet 13, wherein the air flow entering from the bottom air inlet 11 can be heat-exchanged with the bottom heat exchanger 3, the air flow entering from the first air inlet 12 can be heat-exchanged with the first heat exchanger 4, and the air flow entering from the second air inlet 13 can be heat-exchanged with the second heat exchanger 5, so as to realize the temperature adjustment of the air flow, and the heat-exchanged air flow converges to the air outlet 14 under the action of the centrifugal fan 2 and is discharged through the air outlet 14, thereby meeting the use needs of indoor refrigeration and heating.

[0049] The projections of the first heat exchanger 4 and the second heat exchanger 5 on the vertical plane parallel to the length direction are both V-shaped, and the first heat exchanger 4 and the second heat exchanger 5 both protrude to the side away from the centrifugal fan 2.

[0050] For example, as shown in Figure 1 The length direction can be the left-right direction, and the vertical plane can be a vertical plane parallel to the left-right direction. The first heat exchanger 4 and the second heat exchanger 5 can both be V-shaped plate structures, in the left-right direction, the first heat exchanger 4 can be arranged between the centrifugal fan 2 and the first air inlet 12, and the middle part of the first heat exchanger 4 can protrude to the first air inlet 12, and the second heat exchanger 5 can be arranged between the centrifugal fan 2 and the second air inlet 13, and the middle part of the second heat exchanger 5 can protrude to the second air inlet 13.

[0051] Therefore, the air flow flowing in through the first air inlet 12 and the second air inlet 13 can be branched under the action of the protruding parts of the first heat exchanger 4 and the second heat exchanger 5, which is beneficial to slow down the flow rate and improve the heat exchange efficiency, and secondly, compared with the straight plate heat exchanger, the V-shaped structure design can also increase the effective heat exchange area of the heat exchanger, thereby further ensuring the sufficiency of heat exchange.

[0052] The air conditioner of the embodiment of the utility model, the air conditioner adopts the design of upper air outlet, that is, compared with the design of lower air outlet, the setting position of the air outlet 14 is higher, so that the air conditioner can have a larger air supply angle, and is also beneficial to improve the overall air supply distance.

[0053] Secondly, the bottom air inlet 11, the first air inlet 12 and the second air inlet 13 are arranged on the shell 1, so that air can enter from the bottom side and the left and right sides of the air conditioner, thereby greatly improving the air inlet area and the unit air inlet volume of the air conditioner, and further improving the indoor air circulation efficiency and circulation speed, which is beneficial to rapid cooling and heating and improves the user experience.

[0054] In some embodiments, as shown in Figures 1 to 3 The centrifugal fan 2 includes a volute 21 and a centrifugal fan blade 22.

The outer circumferential side of the cylindrical portion and the axial ends of the cylindrical portion are open structures, thereby meeting the use requirements of the bottom air inlet 11, the first air inlet 12 and the second air inlet 13 entering the volute 21.

[0056] The tube portion can extend in the front-rear direction, and the rear end of the tube portion can be connected to the cylindrical portion. The front end of the tube portion can also be an open structure and can be connected to the air outlet 14, thereby meeting the use requirements of sending air flow.

[0057] As shown in Figure 1 and Figure 2 The centrifugal fan blade 22 is arranged in the volute 21, and the rotation axis of the centrifugal fan 2 can extend in the left-right direction. When the centrifugal fan 2 operates, air flow can flow into the shell 1 through the bottom air inlet 11, the first air inlet 12 and the second air inlet 13, and after heat exchange with the bottom heat exchanger 3, the first heat exchanger 4 and the second heat exchanger 5, the air flow can enter the volute 21 and finally be discharged through the air outlet 14.

[0058] In some embodiments, the first heat exchanger 4 includes a first section 41 and a second section 42 arranged opposite in the up-down direction. The second section 42 is located below the first section 41, and the connection between the first section 41 and the second section 42 protrudes towards the first air inlet 12.

[0059] For example, as shown in Figure 1As shown, the first heat exchanger 4 can be a split structure, and can include two parts according to different extension directions, i.e., the first section 41 and the second section 42, both of which can be in a flat plate structure. The first section 41 can be arranged in a left-down-to-right-up direction, and the second section 42 can be arranged in a left-up-to-right-down direction.

The third section 51 can be arranged in a left-up-to-right-down direction, and the fourth section 52 can be arranged in a left-down-to-right-up direction.

[0076] It should be noted that, Figure 1 The first heat exchanger 4 and the second heat exchanger 5 in the diagram are only for illustrative purposes and do not represent the specific structural form of the first heat exchanger and the second heat exchanger.

[0077] In some embodiments, the air conditioner includes a water tray 9, which is disposed between the bottom grille 6 and the bottom heat exchanger 3, and in the longitudinal direction, the length dimension M of the water tray 9 is not less than either the distance M1 between the first heat exchanger 4 and the second heat exchanger 5 or the length dimension M2 of the bottom heat exchanger 3.

[0078] For example, such as Figure 1 As shown, the length direction can be left and right, and the water receiving tray 9 can extend along the left and right direction. The length dimension M is the dimension of the water receiving tray 9 in the left and right direction. The distance M1 is the distance in the left and right direction between the outer protrusion of the bend of the first heat exchanger 4 and the outer protrusion of the bend of the second heat exchanger 5. The bottom heat exchanger 3 extends roughly along the left and right direction, and the length dimension M2 is the dimension of the bottom heat exchanger 3 in the left and right direction.

[0079] like Figure 2 As shown, the length dimension M must be greater than the distance M1, and the length dimension M must also be greater than the length dimension M2. Furthermore, the left end of the water receiving tray 9 can extend beyond the left sides of both the bottom heat exchanger 3 and the first heat exchanger 4, and the right end of the water receiving tray 9 can extend beyond the right sides of both the bottom heat exchanger 3 and the second heat exchanger 5. This allows the water receiving tray 9 to simultaneously meet the needs of collecting condensate dripping from the bottom heat exchanger 3, the first heat exchanger 4, and the second heat exchanger 5.

[0080] In some embodiments, such as Figure 2 As shown, the bottom heat exchanger 3 can be a V-shaped structure with the bottom heat exchanger 3 protruding downwards. The water receiving tray 9 can be located directly below the protruding part of the bottom heat exchanger 3, which facilitates the collection of condensate and other liquids dripping from the bottom heat exchanger 3.

[0082] For example, as shown in ​ The base 15 and the panel 16 can be oppositely arranged in the front-rear direction, and the panel 16 can be arranged at the front side of the base 15. The base 15 and the panel 16 can both extend along the left-right direction, the bottom side edges of the base 15 and the panel 16 can be spaced apart in the front-rear direction, the bottom air inlet 11 can be formed between the bottom side edges of the base 15 and the panel 16, and the bottom grille 6 can also be mounted between the bottom side edges of the base 15 and the panel 16.

[0083] The air outlet 14 can be a square opening, the air outlet 14 can be arranged at the panel 16 and penetrate the panel 16 in the front-rear direction, and the air outlet 14 is arranged adjacent to the top side edge of the panel 16, thereby fully meeting the use needs of the upper air outlet.

[0084] The air conditioner of the embodiment of the utility model is applied to an air conditioning system, and the air conditioning system can also comprise an air conditioner outdoor unit, corresponding connecting pipelines and the like. The air conditioning system of the embodiment of the utility model has the advantages of large air supply wind pressure, large air supply angle, long air supply distance, large air supply volume and the like compared with a traditional air conditioner, and the form of the upper air outlet also has the advantages of avoiding cold air directly blowing on a person and the cool feeling being more natural.

[0085] Secondly, the airflow can enter from the bottom, the left side and the right side under the action of the centrifugal fan, and after flowing through the evaporators at the bottom, the left side and the right side, the airflow can flow along the air duct and finally flow out at a certain angle range at the air outlet.

[0086] In this way, on the one hand, the problem of cold air rapidly sinking in the refrigeration mode can be solved, so that the cold air can flow uniformly and slowly to a larger range; on the other hand, the air supply volume and the air supply distance can be greatly improved, so that the airflow can uniformly cover the entire room, the air supply effect is improved, the uniformity of the temperature in the entire room area is ensured, and the overall use comfort of the user is also ensured.
