[0009] In some embodiments, the centrifugal fan includes a volute and an impeller. The volute includes a volute body, a first diffuser section, and a second diffuser section.

[0024] The embodiments of the present invention are described in detail below, examples of which are illustrated 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.

[0025] The following is a reference appendix. Figure 1 and Figure 2 This invention describes an air conditioner according to an embodiment of the present invention.

[0026] like Figure 1 and Figure 2 As shown, the air conditioner of this utility model embodiment includes: a housing 1, a heat exchanger 2, and a centrifugal fan 3. The housing 1 is provided with an air inlet 13, a first air outlet 11, and a second air outlet 12. The air inlet 13 is located on the lower side of the housing 1, the first air outlet 11 is located on the front side of the housing 1, and the second air outlet 12 is located on the upper side of the housing 1. The heat exchanger 2 is located inside the housing 1, and the centrifugal fan 3 is located inside the housing 1. The centrifugal fan 3 has a first exhaust port 3111 and a second exhaust port 3121. The first exhaust port 3111 is connected to the first air outlet 11, and the second exhaust port 3121 is connected to the second air outlet 12.

[0027] According to the embodiment of the present invention, the air conditioner has a first air outlet 11 located on the front side of the housing 1 and a second air outlet 12 located on the upper side of the housing 1. This solves the problem of rapid downward flow of heat exchange air and increases the air supply area of ​​the air conditioner, thereby improving the air outlet effect. Furthermore, since the first exhaust vent 3111 is connected to the first air outlet 11 and the second exhaust vent 3121 is connected to the second air outlet 12, the distribution of heat exchange airflow can be made more balanced.

[0028] Furthermore, the air conditioner in this embodiment of the present invention adopts a bottom air intake and top front air outlet air supply form, which can solve the problem of airflow blowing directly on the user and can make the airflow evenly cover the entire room.

[0029] Furthermore, since the air conditioner of this invention uses a centrifugal fan 3 to drive the heat exchange airflow, compared to a cross-flow fan, it can extend the distance the heat exchange airflow travels from the first air outlet 11 and the second air outlet 12. Therefore, the air conditioner of this embodiment can meet the needs of long-distance air delivery, increase the air delivery area, and help improve the uniformity of room temperature, thereby enhancing the user experience.

[0030] 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 it is actually installed.

[0031] When the air conditioner is running, indoor air is drawn in through the air inlet 13 by the centrifugal fan 3, comes into contact with the heat exchanger 2 for heat exchange, and then the airflow enters the volute 31 through the air intakes on both sides of the centrifugal fan 3. The air is then transported to the exhaust vent by the impeller 32 and finally blown out through the two air outlets (first air outlet 11 and second air outlet 12), achieving bottom air intake and top-front air outlet for the air conditioner. This significantly increases the air outlet area of ​​the air conditioner, allows the airflow to enter the room at a wider angle, and greatly improves the air delivery distance, ensuring excellent air delivery performance.

[0032] When the air conditioner is in cooling mode, the cool air flows along a large area of ​​the upper part of the room, achieving rapid cooling and improving human comfort. In heating mode, the warm air flows along the lower part of the room, creating a carpet-like breeze that evenly covers the entire room, ensuring overall user comfort. Furthermore, the air conditioner in this embodiment effectively avoids direct airflow onto the human body, enhancing the user experience.

[0033] Optionally, such as Figure 1 and Figure 2As shown, the housing 1 is provided with a first air duct 14 and a second air duct 15. The first air duct 14 extends along the front-to-back direction of the housing 1. One end of the first air duct 14 is connected to the first exhaust port 3111, and the other end of the first air duct 14 is connected to the first air outlet 11. Because the first air duct 14 extends along the front-to-back direction, it can blow the heat exchange airflow horizontally, allowing the heat exchange airflow to flow over a large area within the room. The second air duct 15 gradually extends forward at an angle from bottom to top. One end of the second air duct 15 is connected to the second exhaust port 3121, and the other end of the second air duct 15 is connected to the second air outlet 12. Therefore, the second air duct 15 can blow the heat exchange airflow upward at an angle, allowing the heat exchange airflow to flow over a large area along the upper side of the room.

[0034] On the other hand, since the two ends of the first air duct 14 are connected to the first exhaust port 3111 and the first air outlet 11 respectively, and the two ends of the second air duct 15 are connected to the second exhaust port 3121 and the second air outlet 12 respectively, when the centrifugal fan 3 is working, under the action of the first air duct 14 and the second air duct 15, a portion of the heat exchange airflow flows directly from the first air duct 14 to the first air outlet 11, and another portion of the heat exchange airflow flows directly from the first air duct 14 to the second air outlet 12. This makes the airflow discharged from the first air outlet 11 and the second air outlet 12 more balanced.

[0035] In one example, such as Figure 2 As shown, the angle between the extension direction of the second air duct 15 and the front-rear direction of the housing 1 is α, where 20°≤α≤80°. In other words, the angle between the discharge direction of the main airflow in the second air duct 15 and the horizontal plane is α. For example, α can be 20°, 40°, 50°, 60°, or 80°. Preferably, α is selected between 40° and 60°.

[0036] The air conditioner of this utility model, by designing the second air duct 15 with the above-described structure, can ensure that the heat exchange airflow of the second air duct 15 can be effectively sent forward, and can avoid the problem of the heat exchange airflow of the second air duct 15 mixing with the heat exchange airflow of the first air duct 14, which is beneficial to improving the air outlet efficiency.

[0037] In some embodiments, such as Figure 1 and Figure 2As shown, the centrifugal fan 3 includes a volute 31 and an impeller 32. The volute 31 includes a volute body 313, a first diffuser section 311, and a second diffuser section 312. The impeller 32 is disposed inside the volute body 313. Both the first diffuser section 311 and the second diffuser section 312 are connected to the volute body 313. At least a portion of the first diffuser section 311 extends into the first air duct 14, that is, at least a portion of the wall surface of the first diffuser section 311 overlaps with the wall surface of the first air duct 14. The front end of the first diffuser section 311 forms a first exhaust port 3111. Since at least a portion of the first diffuser section 311 extends into the first air duct 14, the probability of air leakage at the connection point between the first diffuser section 311 and the first air duct 14 can be reduced, meaning that the heat exchange airflow of the first diffuser section 311 can be completely introduced into the first air duct 14.

[0038] At least a portion of the second diffuser section 312 extends into the second air duct 15, meaning that at least a portion of the wall surface of the second diffuser section 312 overlaps with the wall surface of the second air duct 15, and the upper end of the second diffuser section 312 forms the second exhaust port 3121. Because at least a portion of the second diffuser section 312 extends into the second air duct 15, the probability of air leakage at the connection point between the second diffuser section 312 and the second air duct 15 can be reduced; that is, the heat exchange airflow of the second diffuser section 312 can be completely guided into the second air duct 15.

[0039] Optionally, such as Figure 1 and Figure 2 As shown, the volute 31 also includes a flow-diverting cone 314, which is located at the connection between the first diffuser section 311 and the second diffuser section 312. The flow-diverting cone 314 gradually decreases in size along its vertical direction from front to back. It can be understood that the flow-diverting cone 314 forms part of the wall surface of the volute 31, and is used to smoothly divert the heat exchange airflow to the first diffuser section 311 and the second diffuser section 312. In a cross-section orthogonal to the axis of the centrifugal fan 3, the flow-diverting cone 314 is generally triangular, with its tip pointing rearward. Figure 1 As shown, the tip of the flow divider cone 314 extends gradually backward in a front-to-back direction and is slightly inclined downward. Thus, the flow divider cone 314 can evenly distribute the heat exchange airflow from the volute body 313 to the first diffuser section 311 and the second diffuser section 312, and can reduce the air resistance when distributing the heat exchange airflow to the first diffuser section 311 and the second diffuser section 312, thereby reducing the energy consumption of the air conditioner.

[0040] For example, such as Figure 1As shown, the rear end (tip of the flow divider cone 314) of the flow divider cone 314 has a rearwardly convex arc surface 3141. It can be understood that the heat exchange airflow led out by the volute body 313 will impact the arc surface 3141 at the rear end of the flow divider cone 314. Under the guiding effect of the arc surface 3141, the heat exchange airflow can be smoothly divided to the first diffuser section 311 and the second diffuser section 312, so as to further reduce the wind resistance when the heat exchange airflow is distributed to the first diffuser section 311 and the second diffuser section 312, and reduce the energy consumption of the air conditioner.

[0041] Optionally, the first air duct 14 is arranged to gradually widen from back to front, and the second air duct 15 is arranged to gradually widen from bottom to top. This can significantly increase the air outlet area of ​​the first air outlet 11 and the second air outlet 12, so that the heat exchange airflow can be blown into the room at a larger angle, and the air supply distance can also be greatly improved, ensuring good air supply effect.

[0042] In some embodiments, such as Figure 1 and Figure 2 As shown, the housing 1 has a front panel 16, and a first air outlet 11 is disposed on the front panel 16. The first air outlet 11 is arranged near the upper edge of the front panel 16, which can solve the problem of the airflow sinking quickly and facilitate the airflow to flow evenly in a large area of ​​the room. This can ensure the temperature consistency of each area in the room and improve the user experience.

[0043] like Figure 1 As shown, the front panel 16 gradually tilts backward from top to bottom, so that the upper edge of the first air outlet 11 is located in front of the lower edge of the first air outlet 11. The airflow blown out of the first air outlet 11 will be affected by the wall effect and will flow close to the lower edge of the first air outlet 11. This reduces the resistance of air flow, reduces energy consumption, and facilitates the normal blowing of air into the room, ensuring the comfort of the user when blowing air.

[0044] In some embodiments, such as Figure 1 As shown, the air conditioner also includes a first air guide plate 51 and a second air guide plate 52. The first air guide plate 51 is rotatably mounted on the first air outlet 11, and the second air guide plate 52 is rotatably mounted on the second air outlet 12. It can be understood that the first air guide plate 51 and the second air guide plate 52 are each driven by their respective motors. The first air guide plate 51 can adjust the air outlet angle of the first air outlet 11 to guide the airflow from the first air outlet 11 upwards, downwards, or horizontally. The second air guide plate 52 can adjust the air outlet angle of the second air outlet 12 to guide the airflow from the second air outlet 12 upwards or horizontally.

[0045] The air conditioner of this utility model can meet the air supply needs of different working modes of the air conditioner by setting a first air guide plate 51 and a second air guide plate 52 at the positions of the first air outlet 11 and the second air outlet 12 respectively, so as to make the air outlet range of the air conditioner wider.

[0046] Specifically, such as Figure 1 and Figure 2 As shown, the air conditioner also includes a water collection tray 4, which is located inside the housing 1 and at the lower edge of the heat exchanger 2. The water collection tray 4 can collect the water flow condensed on the heat exchange wall of the heat exchanger 2.

[0047] For example, in a cross-section orthogonal to the left and right directions of the shell 1, the heat exchanger 2 has a V-shaped cross-section, with the tip of the heat exchanger 2 facing the air inlet 13 and the open end of the heat exchanger 2 facing the centrifugal fan 3. It can be understood that the V-shaped heat exchanger 2 can increase the heat exchange area, and the condensate on the heat exchanger 2 can be guided along the outer wall of the heat exchanger 2 to the water collection tray 4 for easy collection of condensate.
