[0026] Embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting it.

[0027] The air conditioner 100 of this embodiment includes a housing 1, a heat exchanger 2, at least two centrifugal fans 3, and a partition 4. The housing 1 has a chamber 11, and an air inlet 12 and an air outlet 13 are provided on the housing 1. Both the air inlet 12 and the air outlet 13 communicate with the chamber 11. The air inlet 12 is located at the lower end of the housing 1, and the air outlet 13 is located at the upper end of the housing 1. The heat exchanger 2 is disposed within the chamber 11. The centrifugal fans 3 are disposed within the chamber 11, and the centrifugal fans 3 are located on the side of the heat exchanger 2 away from the air inlet 12. At least two centrifugal fans 3 are arranged along the length of the housing 1 (e.g., ...). Figure 1 The centrifugal fans 3 are arranged at intervals in the left-right direction as shown. The partition 4 is located in the chamber 11 and between adjacent centrifugal fans 3.

[0028] Specifically, such as Figures 1-3 As shown, the air inlet 12 is located at the lower end of the housing 1 with its opening facing downwards, and the air outlet 13 is located at the upper end of the housing 1 with its opening facing forwards. That is to say, the air conditioner 100 is an air conditioner with air inlet at the bottom and air outlet at the top. The centrifugal fan 3 is located in the chamber 11 and above the heat exchanger 2. At least two centrifugal fans 3 are arranged at intervals in the left-right direction, and a partition 4 is provided between two adjacent centrifugal fans 3.

[0029] External airflow can enter the chamber 11 through the lower air inlet 12 and exchange heat through the heat exchanger 2. After heat exchange, the airflow enters at least two centrifugal fans 3 under the obstruction of the partition 4. Under the action of the centrifugal fans 3, the airflow is accelerated and pressurized and blown to the air outlet 13 for discharge.

[0030] Optionally, when there are two centrifugal fans 3, there is one partition 4 located between the two centrifugal fans 3. When there are three centrifugal fans 3, the three centrifugal fans 3 are arranged at intervals in the left-right direction, and there are two partitions 4. The first partition 4 is located between the first centrifugal fan 3 and the second centrifugal fan 3, and the second partition 4 is located between the second centrifugal fan 3 and the third centrifugal fan 3. For ease of description, this embodiment uses two centrifugal fans 3 as an example for detailed explanation.

[0031] Optionally, the heat exchanger 2 includes a first section 21 and a second section 22 connected to each other. The first section 21 of the heat exchanger 2 is located in front of the second section 22. The first section 21 extends from top to bottom and is arranged at a backward inclination. The second section 22 extends from front to back and is arranged at an upward inclination. The lower end of the first section 21 is connected to the lower end of the second section 22, and the top end of the first section 21 is higher than the top end of the second section 22. In a projection plane orthogonal to the left and right directions, the heat exchanger 2 is generally V-shaped or L-shaped, with the V-shaped or L-shaped opening facing upward. This allows the airflow entering the chamber 11 through the lower air inlet 12 to flow along the surface of the heat exchanger 2, increasing the contact area between the airflow and the wall of the heat exchanger 2 and improving the heat exchange efficiency.

[0032] Optionally, the lower end of the centrifugal fan 3 is located in the opening of the heat exchanger 2, so that the airflow after heat exchange by the heat exchanger 2 can enter the centrifugal fan 3 more smoothly.

[0033] Optionally, the air conditioner 100 also includes a base 8 on which the heat exchanger 2 is mounted.

[0034] The air conditioner 100 of this embodiment provides at least two centrifugal fans 3 arranged at intervals along the length of the housing 1 within the chamber 11, and a partition 4 between adjacent centrifugal fans 3. This allows the airflow after heat exchange in the heat exchanger 2 to be divided into at least two parts by the partition 4. Each part of the airflow flows to its corresponding centrifugal fan 3 and is discharged from the upper air outlet 313 under the action of the centrifugal fan 3. This avoids interference between the airflow of adjacent centrifugal fans 3, thereby preventing turbulence between adjacent centrifugal fans 3 and improving the air supply effect of the air conditioner 100. Furthermore, the air conditioner 100 uses an upper air outlet 13 for exhaust, which can effectively prevent the airflow from blowing directly on people and improve the user experience.

[0035] Compared to setting one centrifugal fan 3 in chamber 11, this embodiment sets two centrifugal fans 3 in chamber 11, which makes the length of the centrifugal fans 3 smaller. Under the same air volume, the centrifugal fans 3 in this embodiment are more efficient. Moreover, under the same air volume, the noise of setting two centrifugal fans 3 is at least 2dB lower than that of setting one centrifugal fan 3. The centrifugal fans 3 are more efficient and quieter.

[0036] In some embodiments, such as Figure 1 and Figure 3 As shown, the partition 4 is located at the middle position of the chamber 11 along the length of the shell 1. By placing the partition 4 at the middle position of the shell 1, it is easy to divide the chamber 11 evenly in the left and right directions, so that the airflow is evenly distributed in the left and right directions, improving the stability of the airflow in the chamber 11, and thus improving the efficiency of the centrifugal fan 3.

[0037] In some embodiments, the centrifugal fan 3 includes a volute 31 and an impeller 32. The impeller 32 is disposed inside the volute 31. Both ends of the volute 31 in the axial direction are provided with air inlets 311. The volute 31 has an air outlet channel 312 extending in the front-back direction. The front end of the air outlet channel 312 is an air outlet 313, which is located at the air outlet 13.

[0038] Specifically, such as Figures 1-3As shown, the air inlet 311 is located at the left and right ends of the volute 31. The airflow enters the volute 31 through the left and right air inlets 311. After being accelerated by the impeller 32, the airflow enters the air outlet channel. The air outlet channel extends from back to front, and the front end of the air outlet channel forms the air outlet 313. By connecting the air outlet 313 with the air outlet 13, the airflow in the volute 31 can flow out through the air outlet 313 and the air outlet 13 in sequence.

[0039] In some embodiments, such as Figure 1 and Figure 3 As shown, the cross-sectional area of ​​the baffle 4 in the direction orthogonal to the length of the shell 1 is greater than the cross-sectional area of ​​the impeller 32 in the same direction. By setting the cross-sectional area of ​​the baffle 4 to be greater than that of the impeller 32, it is ensured that the baffle 4 at least separates the impellers 32 of adjacent centrifugal fans 3, preventing airflow from interacting between adjacent impellers 32, thereby preventing airflows flowing towards adjacent impellers 32 from mixing and colliding, reducing eddy current generation, and improving the air delivery effect of the centrifugal fan 3.

[0040] Optionally, the lower end of the baffle 4 is fitted with the upper end face of the heat exchanger 2, the upper end of the baffle 4 is fitted with the inner top surface 111 of the chamber 11, the rear end of the baffle 4 is fitted with the rear side of the chamber 11, and the front end of the baffle 4 is fitted with the front side of the chamber 11, so that the baffle 4 divides the airflow after heat exchange by the heat exchanger 2 into two parts, and the two parts of airflow flow to the two sides of the baffle 4 respectively without interfering with each other.

[0041] In some embodiments, such as Figure 2 As shown, in the cross-section of the centrifugal fan 3, the air outlet channel includes a first wall surface 3121 and a second wall surface 3122 located above the first wall surface 3121. Both the first wall surface 3121 and the second wall surface 3122 extend in a direction from back to front and are arranged at a downward inclination. The angle between the first wall surface 3121 and the inner top surface 111 of the chamber 11 is greater than the angle between the second wall surface 3122 and the inner top surface 111 of the chamber 11.

[0042] By setting both the first wall surface 3121 and the second wall surface 3122 to extend from back to front and be arranged downwardly, the airflow is prevented from blowing directly onto the ceiling or wall, which facilitates the diffusion of the airflow from the air outlet 13. By setting the downward tilt angle of the first wall surface 3121 to be greater than that of the second wall surface 3122, the flow area of ​​the air outlet channel gradually increases from back to front, forming a gradually expanding channel. In other words, the vertical distance between the first wall surface 3121 and the second wall surface 3122 gradually increases from back to front, and the airflow velocity gradually decreases in the gradually expanding channel, thereby pressurizing the airflow and improving the air supply pressure and air supply distance of the air conditioner 100.

[0043] In some embodiments, the housing 1 includes a front panel 14, an air outlet 13 is disposed at the upper end of the front panel 14, the front side of the front panel 14 is arranged to be inclined backward in the direction from top to bottom, and the front end face of the air outlet 313 is coplanar with the front end face of the air outlet 13.

[0044] Specifically, such as Figure 2 As shown, the front panel 14 is located at the front end of the housing 1. The front side of the front panel 14 forms the front end face of the housing 1. The front side of the front panel 14 extends from top to bottom and is arranged to tilt backward, such that the upper end of the front side of the front panel 14 is located in front of the lower end of the front side of the front panel 14.

[0045] By setting an air outlet 13 with a forward opening at the upper end of the front panel 14, and setting the front end face of the air outlet 13 and the front end face of the air outlet 313 to be coplanar, the airflow from the air outlet channel can flow directly out through the air outlet 13. A portion of the airflow will flow downwards along the extension direction of the front side of the front panel 14. The further down the airflow flows, the further back it goes, making it easier to flow downwards and land on the ground, and increasing the distance the airflow travels on the ground.

[0046] In some embodiments, at least two centrifugal fans 3 include a first centrifugal fan 33 and a second centrifugal fan 34 arranged adjacent to each other, a partition 4 is located between the first centrifugal fan 33 and the second centrifugal fan 34, the outer diameter of the impeller 32 of the first centrifugal fan 33 is R1, and the distance between the partition 4 and the first centrifugal fan 33 in the length direction of the housing 1 is L1, wherein 0.2R1≤L1≤R1.

[0047] Specifically, such as Figure 1 and Figure 3 As shown, the first centrifugal fan 33 and the second centrifugal fan 34 are arranged at intervals in the left-right direction. The first centrifugal fan 33 is located to the left of the second centrifugal fan 34, or the second centrifugal fan 34 is located to the left of the first centrifugal fan 33. The partition 4 is provided between the first centrifugal fan 33 and the second centrifugal fan 34. The partition 4 divides the airflow after heat exchange by the heat exchanger 2 into a first airflow and a second airflow. The first airflow flows to the first centrifugal fan 33, and the second airflow flows to the second centrifugal fan 34.

[0048] In this embodiment, the first centrifugal fan 33 is located to the left of the second centrifugal fan 34 as an example. By limiting the distance between the right end of the first centrifugal fan 33 and the left end of the partition 4 in the left-right direction, it is possible to avoid L1 being too small, which would increase the resistance of the first airflow and affect the efficiency of the first centrifugal fan 33. At the same time, it is also possible to avoid L1 being too large, which would increase the size of the air conditioner 100 in the left-right direction. By limiting the relationship between L1 and R1, it is ensured that the first airflow smoothly enters the first centrifugal fan 33 through the right air inlet 311, thereby improving the operating efficiency of the first centrifugal fan 33.

[0049] In some embodiments, such as Figure 3 As shown, the outer diameter of the impeller 32 of the second centrifugal fan 34 is R2, and the distance between the partition 4 and the second centrifugal fan 34 along the length of the housing 1 is L2, where 0.2R2≤L2≤R2. By limiting the distance between the left end of the second centrifugal fan 34 and the right end of the partition 4 in the left-right direction, L2 is prevented from being too small, which would increase the resistance of the second airflow and affect the efficiency of the second centrifugal fan 34. At the same time, L2 is prevented from being too large, which would increase the size of the air conditioner 100 in the left-right direction. By limiting the relationship between L2 and R2, it is ensured that the second airflow smoothly enters the second centrifugal fan 34 through the left air inlet 311, thereby improving the operating efficiency of the second centrifugal fan 34.

[0050] In some embodiments, such as Figure 3 As shown, the first centrifugal fan 33 has a length dimension of L3 along the length of the casing 1, where 0.6R1≤L3≤1.6R1. By defining the relationship between L3 and R1, it is convenient to limit the air volume and air pressure of the first centrifugal fan 33, reduce the loss of the first airflow in the first centrifugal fan 33, and improve the efficiency of the first centrifugal fan 33.

[0051] In some embodiments, such as Figure 3 As shown, the second centrifugal fan 34 has a length dimension of L4 in the length direction of the housing 1, where 0.6R2≤L4≤1.6R2. By limiting the relationship between L4 and R2, it is convenient to limit the air volume and air pressure of the second centrifugal fan 34, reduce the loss of the second airflow in the second centrifugal fan 34, and improve the efficiency of the second centrifugal fan 34.

[0052] In some embodiments, the chamber 11 includes a first side 112 and a second side 113 arranged opposite to each other in the length direction of the housing 1. The first side 112 is adjacent to the first centrifugal fan 33 and the distance between them is L5, 0.3R1≤L5≤1.2R1. The second side 113 is adjacent to the second centrifugal fan 34 and the distance between them is L6, 0.3R2≤L6≤1.2R2.

[0053] Specifically, such as Figure 3As shown, the first side 112 is the left side of the chamber 11, and the second side 113 is the right side of the chamber 11. By limiting the distances L5 and R1 between the first side 112 and the left end face of the first centrifugal fan 33, we avoid L5 being too small, which would increase airflow resistance, and at the same time avoid L5 being too large, which would increase the size of the air conditioner 100. This ensures that there is a suitable air inlet distance between the first centrifugal fan 33 and the first side 112, so that the first airflow can smoothly enter the first centrifugal fan 33 through the left air inlet 311, thereby improving the operating efficiency of the first centrifugal fan 33.

[0054] By limiting the distances L6 and R2 between the second side 113 and the right end face of the second centrifugal fan 34, we avoid L6 being too small, which would increase airflow resistance, and at the same time avoid L6 being too large, which would increase the size of the air conditioner 100. This ensures that there is a suitable air inlet distance between the second centrifugal fan 34 and the second side 113, so that the second airflow can smoothly enter the second centrifugal fan 34 through the right air inlet 311, thereby improving the operating efficiency of the second centrifugal fan 34.

[0055] In some embodiments, there are at least two air outlets 13, and each of the at least two air outlets 13 corresponds to at least two centrifugal fans 3. By having at least two air outlets 13 correspond to at least two centrifugal fans 3, zoned air supply can be implemented according to different user needs, thereby improving the user experience.

[0056] In some embodiments, such as Figure 1 and Figure 2 As shown, the air conditioner 100 also includes a water collection tray 5, which is located inside the chamber 11 and below the heat exchanger 2. By placing the water collection tray 5 below the heat exchanger 2, it is convenient to collect the condensate on the heat exchanger 2, preventing the condensate from flowing out through the air inlet 12 and improving the user experience.

[0057] In some embodiments, such as Figure 1 and Figure 2 As shown, the air conditioner 100 also includes an air inlet grille 6, which is located at the air inlet 12. The air inlet grille 6 facilitates airflow guidance while preventing foreign objects from entering the housing 1 through the air inlet 12, thus improving safety.

[0058] Optionally, there are at least two air inlet grilles 6, and the at least two air inlet grilles 6 are arranged in a one-to-one correspondence with at least two air outlets 13 to achieve air guidance from different air outlets 13.

[0059] In some embodiments, such as Figure 1As shown, the air conditioner 100 also includes an air guide plate 7, which is located at the air outlet 13. The air guide plate 7 can rotate in the left-right direction and in the up-down direction relative to the housing 1, so as to realize the up-down rotation and left-right swing of the air guide plate 7 relative to the housing 1, which facilitates the guidance of airflow.
