[0026] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] The following is a reference appendix. Figures 1 to 4 This invention describes an air conditioner according to an embodiment of the present invention.

[0028] like Figures 1 to 4 As shown, the air conditioner of this utility model embodiment includes: a housing 1, a heat exchanger 2, and two centrifugal fans 3. The housing 1 is provided with an air inlet 11 and two air outlets 12. The air inlet 11 is located on the lower side of the housing 1, and the two air outlets 12 are respectively located on the left and right sides of the housing 1. The heat exchanger 2 is disposed inside the housing 1, and the two centrifugal fans 3 are both disposed inside the housing 1 and located above the heat exchanger 2. The air outlets of the two centrifugal fans 3 are respectively connected to the air outlets 12.

[0029] It should be noted that the up, down, front, back, left, and right directions of the casing 1 are consistent with the up, down, front, back, left, and right directions of the air conditioner after installation.

[0030] According to the embodiment of the present invention, since the two air outlets 12 are respectively located on the left and right sides of the housing 1, compared with the solution of placing the air outlets 12 on the front side of the housing 1, the airflow from the heat exchanger 2 blown out by the air outlets 12 can be prevented from blowing directly onto the user. It can be understood that the air outlets 12 are not provided on the front panel 15 of the air conditioner of the embodiment of the present invention, but only on the left and right sides of the housing 1. Therefore, the heat exchange airflow discharged by the air conditioner will not blow directly forward onto the user, thereby effectively improving the user experience.

[0031] On the other hand, since the air conditioner uses a centrifugal fan 3 to guide the heat exchange airflow, compared with the solution of setting a cross-flow fan, the air supply distance of the air conditioner can be extended to promote the airflow in the room, thereby ensuring the uniformity of temperature in all areas of the room.

[0032] Therefore, the air conditioner of the embodiment of the utility model adopts lateral air outlet, cannot directly blow the user, can effectively improve the user experience, and the air supply distance is longer, which is beneficial to ensure the uniformity of the temperature of each area in the room.

[0033] Optionally, as shown in Figure 3 and Figure 4 , the centrifugal fan 3 includes an impeller 32 and a volute 31, the impeller 32 is arranged in the volute 31, and the rotation axis of the impeller 32 is parallel to the front-rear direction of the shell 1. It can be understood that the suction end of the centrifugal fan 3 is located on one side of the rotation axis of the volute 31, and since the rotation axis of the impeller 32 is parallel to the front-rear direction of the shell 1, when the two centrifugal fans 3 are working, the air flow disturbance caused by the two centrifugal fans 3 when inhaling the heat exchange air flow can be reduced. In other words, the two centrifugal fans 3 do not interfere with each other when inhaling the heat exchange air flow, which is beneficial to improve the flow guiding efficiency of the centrifugal fan 3 and reduce energy consumption.

[0034] In an example, as shown in Figure 3 and Figure 4 , the two volutes 31 are spaced apart by a predetermined distance along the left-right direction of the shell 1, and the two volutes 31 are located at the same horizontal height. It can be understood that the two volutes 31 are spaced apart along the left-right direction of the shell 1 to further reduce the air flow disturbance caused by the two centrifugal fans 3 when working, and improve the flow guiding efficiency of the centrifugal fan 3. In addition, since the two volutes 31 are located at the same horizontal height, the space occupation in the up-down direction of the shell 1 can be reduced, and the structure design is compact and the use effect is good.

[0035] Optionally, as shown in Figure 3 and Figure 4 , the volute 31 includes a volute body 311 and a diffuser section 312, one end of the diffuser section 312 communicates with the volute body 311, and the other end of the diffuser section 312 constitutes an air outlet end and abuts against the inner wall of the shell 1. It can be understood that the diffuser section 312 directly communicates with the air outlet 12. In other words, the heat exchange air flow guided by the diffuser section 312 is all discharged by the corresponding air outlet 12. Compared with the scheme that the diffuser section 312 is spaced apart from the air outlet 12, the flow guiding efficiency of the centrifugal fan 3 can be improved, the air resistance is reduced, and the air supply distance of the air conditioner is prolonged.

[0036] It can be understood that when the air conditioner is running, indoor air is sucked from the air inlet 11 on the lower side of the shell 1 under the action of the centrifugal fan 3, and then contacts the heat exchanger 2 to exchange heat, and then the airflow enters the volute 31 of the centrifugal fan 3 through the air inlet on the axial two sides of the centrifugal fan 3, is transported to the diffuser section 312 by the impeller 32, and finally is blown out through the two air outlets 12, realizing the air conditioner lower air inlet and left and right air outlet. Affected by the air duct structure, the air outlet area of the air conditioner is significantly increased, the airflow can be blown into the indoor at a large angle range, and the air supply distance can also be greatly improved, ensuring good air supply effect.

[0037] In the refrigeration mode, the cold air flows along the upper side of the room in a large range, which can achieve the purpose of rapid cooling and improve the comfort of the human body. In the heating mode, the hot air flows along the lower side of the room to form a carpet wind, and the airflow uniformly covers the entire room, ensuring the overall comfort of the user. The air conditioner of the embodiment of the present application can effectively avoid direct blowing of the airflow to the human body, improve the user experience, and reduce discomfort.

[0038] Optionally, as shown in Figure 4 The diffuser section 312 gradually extends downward in the direction towards the air outlet end. In this way, the amount of air flowing along the top of the heat exchange airflow can be reduced, ensuring that most of the heat exchange airflow can uniformly flow towards a large range of space in the room, which is beneficial to improve the air supply effect and efficiency.

[0039] Specifically, as shown in Figure 4 The diffuser section 312 has oppositely arranged first and second air duct surfaces 3121 and 3122, the first air duct surface 3121 is located on the upper side of the second air duct surface 3122, and the inclination angle of the first air duct surface 3121 with the horizontal plane is smaller than that of the second air duct surface 3122 with the horizontal plane. It can be understood that the second air duct surface 3122 is inclined downward to a greater extent. In this way, a part of the blown airflow flows downward, so that the temperature of the upper and lower regions in the room is more uniform. And the air conditioner of the embodiment of the present application can increase the blowing distance on the basis of large-angle blowing by setting the diffuser section 312 to the above structure, so as to ensure that the air conditioner has good air supply effect.

[0040] In some embodiments, as shown in Figure 3As shown, the heat exchanger 2 is a straight-plate heat exchanger or an arc-shaped heat exchanger, and the heat exchanger 2 gradually extends downward along the front-to-rear direction. The air conditioner further comprises a water pan 4, which is located in the shell 1 and arranged at the lower edge of the rear end of the heat exchanger 2. Due to the above arrangement of the heat exchanger 2, the rear area in the shell 1 can be used to accommodate the centrifugal fan 3 to avoid the installation of the centrifugal fan 3, and most of the heat exchange airflow can be integrated in the rear area of the shell 1 (i.e., the area where the centrifugal fan 3 is installed), which is beneficial to improve the heat exchange efficiency of the air conditioner and the compact structure design, and is beneficial to improve the space utilization of the components in the shell 1.

[0041] The water pan 4 is arranged at the lower edge of the rear end of the heat exchanger 2, and the water pan 4 can collect the condensed water condensed on the fins of the heat exchanger 2. Optionally, the included angle between the heat exchange wall of the heat exchanger 2 and the front-to-rear direction of the shell 1 is α, wherein 20°≤α≤50°. For example, α can be 20°, 30°, 35°, 40°, or 50°.

[0042] When α is too small (i.e., α is less than 20°), the condensed water on the heat exchanger 2 is prone to vertically falling downward under the action of gravity, i.e., the condensed water on the heat exchanger 2 is not easy to flow along the inclined surface of the heat exchanger 2. When α is too large (i.e., α is greater than 50°), the air conditioner will have a large size in the height direction, the space utilization of the components in the shell 1 is low, and the structure is unreasonable. Therefore, α is selected between 20° and 50°, which can improve the flow effect of the condensed water on the heat exchanger 2, the air conditioner is not prone to water leakage, and the structure design is reasonable and the space utilization is high.

[0043] Optionally, as shown in Figures 2 to 4 The shell 1 comprises a top wall 13 and a bottom wall 14, the top wall 13 and the bottom wall 14 are located at the upper and lower sides of the shell 1 respectively, the air inlet 11 is arranged on the bottom wall 14, and the two air outlets 12 are located at the same horizontal height and arranged close to the top wall 13. It can be understood that the air outlet 12 is arranged at the upper position of the side wall of the shell 1, thereby facilitating the airflow to flow uniformly to a larger space in the room, and the air supply effect is good.

[0044] Optionally, as shown in Figure 2 and Figure 3 The air conditioner further comprises a guide vane 5, which is rotatably installed at the air outlet 12. Therefore, the air supply range of the air conditioner can be increased, and the blowing angle requirements of different users can be met, thereby improving the user experience.
