[0024] 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.

[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. An air inlet 13 is provided on the lower side of the housing 1, and a first air outlet 11 and a second air outlet 12 are provided on the front side of the housing 1. The first air outlet 11 is located above the second air outlet 12. The heat exchanger 2 is disposed inside the housing 1, and the centrifugal fan 3 is disposed 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 communicates with the first air outlet 11, and the second exhaust port 3121 communicates with the second air outlet 12.

[0027] According to the embodiment of the present invention, since the front side of the housing 1 is provided with a first air outlet 11 and a second air outlet 12, the air conditioner can use two air outlets to simultaneously discharge air, thereby increasing the air supply area of ​​the air conditioner. 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 heat exchange airflow distribution can be more balanced, and turbulence during heat exchange airflow distribution can be avoided, which is beneficial to improving the air outlet effect.

[0028] Furthermore, the air conditioner in this embodiment of the present invention adopts a bottom air intake and front air outlet air supply form, which can solve the problem of airflow blowing directly on the user and the problem of cold air sinking rapidly in the cooling mode. This allows the airflow to evenly cover the entire room and improves the air supply effect.

[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 contains a first air duct 14 and a second air duct 15. The first air duct 14 is located above the second air duct 15. One end of the first air duct 14 is connected to the first exhaust port 3111, and the other end is connected to the first air outlet 11. One end of the second air duct 15 is connected to the second exhaust port 3121, and the other end is connected to the second air outlet 12. It can be understood that the first exhaust port 3111 is connected to the first air outlet 11 via the first air duct 14, and the second exhaust port 3121 is connected to the second air outlet 12 via the second air duct 15.

[0034] When the centrifugal fan 3 is working, under the action of the first air duct 14 and the second air duct 15, a part of the heat exchange airflow flows directly to the first air outlet 11 through the first air duct 14, and another part of the heat exchange airflow flows directly to the second air outlet 12 through the first air duct 14. This makes the airflow discharged from the first air outlet 11 and the second air outlet 12 more uniform.

[0035] like Figure 1 and Figure 2 As 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 the first exhaust port 3111. Since at least a portion of the first diffuser section 311 extends into the first air duct 14, the problem of air leakage at the connection between the first diffuser section 311 and the first air duct 14 can be reduced, that is, the heat exchange airflow of the first diffuser section 311 can be completely introduced into the first air duct 14.

[0036] like Figure 1 and Figure 2 As shown, 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 front 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 problem 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.

[0037] Optionally, such as Figure 1 and Figure 2As shown, the volute 31 also includes a flow divider cone 314, which is located at the connection between the first diffuser section 311 and the second diffuser section 312. The flow divider cone 314 gradually decreases in size along its vertical direction from front to back. It can be understood that within a cross-section orthogonal to the axis of the centrifugal fan 3, the flow divider cone 314 is approximately triangular, with its tip pointing rearward. 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.

[0038] For example, such as Figure 1 As shown, the rear end of the flow divider cone 314 has a rearwardly protruding arc-shaped surface 3141. It can be understood that the heat exchange airflow led out by the volute body 313 will impact the arc-shaped surface 3141 at the rear end of the flow divider cone 314. Under the guiding effect of the arc-shaped 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.

[0039] Optionally, such as Figure 1 and Figure 2 As shown, the second air duct 15 gradually slopes downwards in the direction from back to front. Since the second air duct 15 gradually extends downwards in the direction from back to front, when the air conditioner is in heating mode, the hot air blown out by the second air outlet 12 can flow downwards under the guidance of the second air duct 15, thereby creating a carpet effect, which helps to evenly cover the entire room with hot air.

[0040] Understandably, the first air duct 14 and the second air duct 15 can respectively blow the heat-exchanged airflow to different locations in the room, achieving large-angle airflow, which is beneficial to improving the air supply effect and efficiency of the air conditioner, as well as the uniformity of temperature in various locations in the room.

[0041] In one example, the lower wall surface of the second air duct 15 includes a first air duct surface 151 and a second air duct surface 152. The second air duct surface 152 is located between the lower edges of the first air duct surface 151 and the second air outlet 12. The first air duct surface 151 and the second air duct surface 152 can be connected by an arc transition.

[0042] like Figure 1As shown, the angle between the first air duct surface 151 and the front-rear direction of the shell 1 is α, and the angle between the second air duct surface 152 and the vertical direction of the shell 1 is β, where 10°≤α≤90° and 30°≤β≤90°. For example, α can be 10°, 20°, 30°, 50°, 70°, 80°, or 90°. β can be 30°, 40°, 50°, 60°, 70°, 80°, or 90°. When α and β are selected within the above ranges, the problem of mixing between the airflow angle of the first air duct 14 and the heat exchange airflow of the second air duct 15 can be avoided. At the same time, the problem of the airflow angle of the second air duct 15 being too low, which would prevent the airflow from being delivered forward smoothly, can be avoided. This also prevents the airflow from blowing directly on the human body and improves the user experience.

[0043] Preferably, α is selected between 50° and 80°, and β is selected between 60° and 90°.

[0044] 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 and a second air outlet 12 are both located on the front panel 16. The first air outlet 11 is arranged near the upper edge of the front panel 16, and the second air outlet 12 is arranged near the middle of the front panel 16. This solves the problem of the airflow sinking quickly and facilitates the airflow to flow evenly in a large area of ​​the room, thereby ensuring the temperature consistency of each area in the room and improving the user experience.

[0045] Optionally, the front panel 16 gradually tilts backward in a top-to-bottom direction, 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, and the upper edge of the second air outlet 12 is located in front of the lower edge of the second air outlet 12. The airflow from the first air outlet 11 and the second air outlet 12 will be affected by the wall effect and will flow close to the lower edge of the first air outlet 11 and the lower edge of the second air outlet 12. This reduces the resistance of airflow, reduces energy consumption, and facilitates the normal blowing of air into the room, ensuring the comfort of the user when blowing air.

[0046] 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 installed at the first air outlet 11, and the second air guide plate 52 is rotatably installed at the second air outlet 12.

[0047] Understandably, 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 upward, downward, 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 upward, downward, or horizontally.

[0048] 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.

[0049] 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.

[0050] For example, such as Figure 1 As shown, heat exchanger 2 is generally V-shaped, with the opening of the V-shape facing upwards and the tip of the V-shape facing the water collection tray 4. The front end of heat exchanger 2 abuts against the lower wall of the second air duct 15, and the rear end of heat exchanger 2 abuts against the inner wall of the base 17. It can be understood that the V-shaped heat exchanger 2 increases the heat exchange area, and the condensate condensed on heat exchanger 2 can be guided along the outer wall of heat exchanger 2 to the water collection tray 4 for easy collection.
