[0040] The embodiments of the utility model are described in detail below, and the examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the utility model, and cannot be understood as the limitation of the utility model.

[0041] As Figure 1 shown, the air conditioner of the embodiment of the utility model comprises a shell 1, a centrifugal fan 2, a bottom heat exchanger 3, a first heat exchanger 4 and a second heat exchanger 5.

[0042] 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 at the side of the shell 1 and 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.

[0043] For example, as shown in Figure 1 and Figure 3 , 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 at the bottom surface of the shell 1, the first air inlet 12 can be arranged at the left side surface of the shell 1, the second air inlet 13 can be arranged at the right side surface of the shell 1, and the air outlet 14 can be arranged at the front side surface of the shell 1 and adjacent to the top surface of the shell 1.

[0044] The centrifugal fan 2 is arranged in the shell 1, and the bottom heat exchanger 3 is arranged between the bottom air inlet 11 and the centrifugal fan 2 and used for heat exchange with the air flow flowing from the bottom air inlet 11. For example, as shown in Figure 1 and Figure 3 , the centrifugal fan 2 can be fixed in the shell 1, and the bottom heat exchanger 3 can also be arranged 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.

[0045] The first heat exchanger 4 is arranged between the first air inlet 12 and the centrifugal fan 2 and used for heat exchange with the air flow 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 used for heat exchange with the air flow flowing from the second air inlet 13.

[0046] 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.

[0047] When the centrifugal fan 2 operates, the external air can be sucked into the shell 1 through the above-mentioned bottom air inlet 11, first air inlet 12 and second air inlet 13, respectively, 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 adjustment of the temperature of the air flow. The heat-exchanged air flow will converge to the air outlet 14 under the action of the centrifugal fan 2 and be discharged through the air outlet 14, thereby meeting the use needs of indoor refrigeration and heating.

[0048] 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 wave shapes 10 and reciprocally folded in the length direction. For example, as shown inFigure 1 As shown, the length direction can be the left-right direction, 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 generally W-shaped in cross section, the first heat exchanger 4 and the second heat exchanger 5 can both extend along the front-rear direction, so that the projections of the first heat exchanger 4 and the second heat exchanger 5 on the vertical plane are both similar to W, i.e., the projections are zigzag in the left-right direction, and the first heat exchanger 4 and the second heat exchanger 5 are generally arranged in mirror image in the left-right direction.

[0049] The air conditioner of the embodiment of the utility model, the air conditioner adopts the design of upper air outlet, namely, 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 it is also beneficial to improve the overall air supply distance.

[0050] Secondly, the shell 1 is provided with three air inlets, i.e., the bottom air inlet 11, the first air inlet 12 and the second air inlet 13, 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 amount of the air conditioner, and further improving the indoor air circulation efficiency and circulation speed, which is beneficial to realize rapid cooling and heating and improve the user experience.

[0051] In addition, the first heat exchanger 4 and the second heat exchanger 5 are both designed in the W shape, so that the heat exchange area is larger than that of the inclined plate evaporator, the U-shaped evaporator and the V-shaped evaporator, thereby realizing higher heat transfer efficiency in a smaller space and improving the refrigeration and heating effects of the air conditioner. The W-shaped design is also helpful to improve the distribution of gas in the entire heat exchanger, so that each region can effectively participate in the heat exchange process, thereby ensuring the sufficiency of heat exchange.

[0052] In some embodiments, the waveform 10 includes a first segment 101, a second segment 102, a third segment 103 and a fourth segment 104 connected in sequence along a direction from top to bottom, the connection between the first segment 101 and the second segment 102 and the connection between the third segment 103 and the fourth segment 104 both protrude away from one side of the centrifugal fan 2, and the connection between the second segment 102 and the third segment 103 protrudes toward the centrifugal fan 2.

[0053] For example, as shown in FIG. 1, the waveform 10 includes a first segment 101, a second segment 102, a third segment 103 and a fourth segment 104 connected in sequence along a direction from top to bottom. Figure 2As shown, waveform 10 can be divided into four segments according to the different directions of extension: segment 101, segment 102, segment 103, and segment 104. Segments 101, 102, 103, and 104 are arranged sequentially from top to bottom, and adjacent segments are connected. The connection between segment 101 and segment 102 forms the first connection point 105, the connection between segment 103 and segment 104 forms the second connection point 106, and the connection between segment 102 and segment 103 forms the third connection point 107.

[0054] like Figure 1 As shown, the first connection 105 and the second connection 106 of the first heat exchanger 4 can both protrude to the left, and the third connection 107 of the first heat exchanger 4 can protrude to the right. Similarly, the first connection 105 and the second connection 106 of the second heat exchanger 5 can both protrude to the right, and the third connection 107 of the second heat exchanger 5 can protrude to the left. This undulating design of the heat exchangers increases the heat exchange area and fully ensures sufficient heat exchange.

[0055] In some embodiments, the distance between the first connection 105 of the first heat exchanger 4 and the first air inlet 12 is L1, where 10mm ≤ L1 ≤ 70mm. For example, as... Figure 1 As shown, since the first connection 105 has a certain thickness in the left-right direction, the distance L1 can specifically be the distance between the left side wall of the first connection 105 of the first heat exchanger 4 and the first air inlet 12, and the distance L1 can specifically be 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, etc. This helps to ensure the air volume flowing in through the first air inlet 12.

[0056] In some embodiments, the distance between the second connection 106 of the first heat exchanger 4 and the first air inlet 12 is L2, where 10mm ≤ L2 ≤ 70mm. For example, as... Figure 1 As shown, the distance L2 can specifically be the distance between the left side wall of the second connection 106 of the first heat exchanger 4 and the first air inlet 12, and the distance L2 can specifically be 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, etc. This helps to ensure the amount of air flowing in through the first air inlet 12.

[0057] In some embodiments, the distance between the first connection 105 and the second air inlet 13 of the second heat exchanger 5 is L3, where 10mm ≤ L3 ≤ 70mm. For example, as... Figure 1As shown, the distance L3 can specifically be the distance between the right side wall of the first connection 105 of the second heat exchanger 5 and the second air inlet 13, and the distance L3 can specifically be 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, etc. This helps to ensure the amount of air flowing in through the second air inlet 13.

[0058] In some embodiments, the distance between the second connection 106 and the second air inlet 13 of the second heat exchanger 5 is L4, where 10mm ≤ L4 ≤ 70mm. For example, as... Figure 1 As shown, the distance L4 can specifically be the distance between the right side wall of the second connection 106 of the second heat exchanger 5 and the second air inlet 13, and the distance L4 can specifically be 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, etc. This helps to ensure the amount of air flowing in through the second air inlet 13.

[0059] In some embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, the centrifugal fan 2 includes a volute 21 and a centrifugal fan blade 22. The volute 21 is connected to the bottom air inlet 11, the first air inlet 12, the second air inlet 13, and the air outlet 14.

[0060] For example, the material of the volute 21 can be metal, plastic, etc. The volute 21 as a whole can be a whistle-shaped structure and include a cylindrical part and a tube part. The outer periphery of the cylindrical part and both ends of the cylindrical part are open structures, thereby meeting the usage requirements of the bottom air inlet 11, the first air inlet 12, and the second air inlet 13 entering the volute 21.

[0061] The tube body can generally extend in the front-to-back direction. The rear end of the tube body can be connected to the cylindrical part, and the front end of the tube body can also be an open structure and connected to the air outlet 14, thus meeting the needs of sending out airflow.

[0062] like Figure 1 and Figure 3 As shown, the centrifugal fan blade 22 is disposed inside the volute 21, and the rotation axis of the centrifugal fan 2 can extend in the left and right direction. When the centrifugal fan 2 is running, the airflow can flow into the housing 1 through the bottom air inlet 11, the first air inlet 12, and the second air inlet 13 respectively. After heat exchange with the bottom heat exchanger 3, the first heat exchanger 4, and the second heat exchanger 5, the airflow can enter the volute 21 and finally be discharged through the air outlet 14.

[0063] In some embodiments, the distance between the third connection 107 of the first heat exchanger 4 and the volute 21 of the centrifugal fan 2 is L5, where 10mm ≤ L5 ≤ 90mm. For example, as...

[0064] In some embodiments, the distance between the third connection 107 of the second heat exchanger 5 and the volute 21 of the centrifugal fan 2 is L6, 10 mm≤L6≤90 mm. For example, as shown in the figure, Figure 1 As shown in the figure, the distance L6 can be specifically the distance between the left side wall surface of the third connection 107 of the second heat exchanger 5 and the right side wall surface of the volute 21, and the distance L6 can be 10 mm, 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, 90 mm, etc. Thus, the distance between the third connection 107 and the volute 21 can be limited within a reasonable range, which is conducive to ensuring the air inlet amount and can also reduce the influence of vibration between the two.

[0065] In some embodiments, the distance between the top end of the first section 101 of the first heat exchanger 4 and the first air inlet 12 is L7, 30 mm≤L7≤100 mm.

[0066] In some embodiments, the distance between the bottom end of the fourth section 104 of the first heat exchanger 4 and the first air inlet 12 is L8, 30 mm≤L8≤100 mm. For example, as shown in the figure, Figure 1 As shown in the figure, the distance L8 can be specifically the distance between the left side wall surface of the bottom end of the fourth section 104 of the first heat exchanger 4 and the first air inlet 12 in the left-right direction, and the distance L8 can be 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, 90 mm, 100 mm, etc. Thus, it is conducive to ensuring the air inlet amount via the first air inlet 12.

[0067] In some embodiments, the distance between the top end of the first section 101 of the second heat exchanger 5 and the second air inlet 13 is L9, 30 mm≤L9≤100 mm. For example, as shown in the figure, Figure 1As shown, the distance L9 can specifically be the distance in the left-right direction between the top right wall of the first section 101 of the second heat exchanger 5 and the second air inlet 13, and the distance L9 can specifically be 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, 100mm, etc. This helps to ensure the air volume entering through the second air inlet 13.

[0069] In some embodiments, the distance between the top of the first section 101 of the first heat exchanger 4 and the volute 21 of the centrifugal fan 2 is L11, where 10mm ≤ L11 ≤ 80mm. For example, as... Figure 1 As shown, the distance L11 can specifically be the distance between the right wall of the top of the first section 101 of the first heat exchanger 4 and the left wall of the volute 21, and the distance L11 can be 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, etc. This allows the distance between the first section 101 and the volute 21 to be limited within a reasonable range, which helps to ensure the air intake volume and also reduces the impact of vibration between the two.

[0070] In some embodiments, the distance between the bottom end of the fourth section 104 of the first heat exchanger 4 and the volute 21 of the centrifugal fan 2 is L12, where 10mm ≤ L12 ≤ 80mm. For example, as... Figure 1 As shown, the distance L12 can specifically be the distance between the right wall of the bottom end of the fourth section 104 of the first heat exchanger 4 and the left wall of the volute 21, and the distance L12 can be 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, etc. This allows the distance between the fourth section 104 and the volute 21 to be limited to a reasonable range, which helps to ensure the air intake volume and also reduces the impact of vibration between the two.

[0071] In some embodiments, the distance between the top of the first section 101 of the second heat exchanger 5 and the volute 21 of the centrifugal fan 2 is L13, where 10mm ≤ L13 ≤ 80mm. For example, as...

[0072] In some embodiments, the distance between the bottom end of the fourth section 104 of the second heat exchanger 5 and the volute 21 of the centrifugal fan 2 is L14, 10 mm≤L14≤80 mm. For example, as shown in FIG. 7, the distance L14 can be specifically the distance between the left side wall surface of the bottom end of the fourth section 104 of the second heat exchanger 5 and the right side wall surface of the volute 21, and the distance L14 can be 10 mm, 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, etc. Thus, the distance between the fourth section 104 and the volute 21 can be limited within a reasonable range, which is conducive to ensuring the air inlet amount and reducing the influence of vibration between the two, etc. Figure 1
