DETAILED DESCRIPTION

[0023] The embodiments of the present utility model are described in detail below, examples of which are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and cannot be understood as a limitation of the present utility model.

[0024] The air conditioner according to an embodiment of the present utility model is described below in combination with Figure 1 and Figure 2

[0025] The air conditioner according to an embodiment of the present utility model includes a shell 1, an evaporator 2, a first cross-flow fan 4, and a second cross-flow fan 5. The upper side of the shell 1 is provided with an air outlet 16, and the bottom of the shell 1 is provided with an air inlet 15. The evaporator 2 is installed in the shell 1, and the evaporator 2 divides the inner cavity of the shell 1 into a first chamber 13 and a second chamber 14. The air outlet 16 is in communication with the first chamber 13, and the air inlet 15 is in communication with the second chamber 14. The first cross-flow fan 4 and the second cross-flow fan 5 are both installed in the first chamber 13.

[0026] The air conditioner according to an embodiment of the present utility model effectively solves the problem of rapid sinking of air flow by setting the air outlet 16 on the upper side of the shell 1, effectively improves the air outlet distance of the air conditioner. At the same time, by installing the first cross-flow fan 4 and the second cross-flow fan 5 in the first chamber 13, compared with the setting of only one fan in the related art, the same direction rotation of the wind wheels of the first cross-flow fan 4 and the second cross-flow fan 5 effectively improves the air outlet volume of the air conditioner, thereby further improving the air outlet distance of the air conditioner and further improving the indoor air circulation efficiency.

[0027] It should be noted that the up-down, front-back, and left-right directions of the shell 1 are consistent with the up-down, front-back, and left-right directions of the air conditioner after actual installation. When the air conditioner is running, the wind wheels of the first cross-flow fan 4 and the second cross-flow fan 5 are both rotating clockwise in the view angle shown in Figure 1

[0028] In some embodiments, as​​Figure 1 and Figure 2 As shown, a partition 111 is provided in the first chamber 13. The partition 111 extends along the length of the shell 1. The partition 111 divides part of the first chamber 13 into a first air guide channel 131 and a second air guide channel 132. At least a portion of the first cross-flow fan 4 and at least a portion of the second cross-flow fan 5 are located in the first air guide channel 131 and the second air guide channel 132, respectively.

[0029] The first chamber 13 is partially divided by the partition 111 to form the first air guide channel 131 and the second air guide channel 132. This effectively avoids the airflow near the first cross-flow fan 4 and the second cross-flow fan 5 from canceling each other out and causing wind power loss. It can also guide the airflow to the air outlet 16 together, further improving the air volume of the air conditioner.

[0030] Specifically, there is one air outlet 16, and the first air guide channel 131 and the second air guide channel 132 are along the width direction of the first chamber 13. Figure 1 Arranged in the front and back directions.

[0031] In some embodiments, such as Figure 1 As shown, both the first air guide channel 131 and the second air guide channel 132 are spaced apart from the evaporator 2. This arrangement allows the incoming airflow to pass through the evaporator 2 and then freely enter the first air guide channel 131 and the second air guide channel 132 under the suction of the first cross-flow fan 4 and the second cross-flow fan 5. The distribution of the incoming airflow is flexible and can ensure the air intake volume when the first cross-flow fan 4 and the second cross-flow fan 5 are started individually.

[0032] Or, such as Figure 2 As shown, the end of each of the first air guide channel 131 and the second air guide channel 132 that is away from the air outlet 16 extends to the evaporator 2.

[0033] This design further avoids airflow loss caused by mutual cancellation near the first cross-flow fan 4 and the second cross-flow fan 5, thereby further increasing the air volume output of the air conditioner.

[0034] Specifically, a sealing element may be connected to the lower end of the partition 111, and the sealing element is sandwiched between the evaporator 2 and the partition 111.

[0035] In some embodiments, on a projection plane perpendicular to the length direction of the housing 1, the projection of the evaporator 2 is a strip, and the extension direction of the projection of the evaporator 2 forms an angle W with the height direction of the housing 1, wherein 35°≤W≤50°.

[0036] The evaporator 2 with the above-mentioned inclination angle can better guide and arrange the airflow passing through, so that the airflow can flow more evenly over the surface of the evaporator 2, and ensure that all parts of the evaporator 2 can fully participate in heat exchange, and better avoid the situation of uneven local heat exchange. At this time, the evaporator 2 also facilitates the condensate water to flow down along the inclined surface and be discharged to the water pan 3, effectively preventing water accumulation in the evaporator 2, reducing the hidden danger of affecting the use of the air conditioner and the indoor air quality due to the breeding of bacteria, mold and the like. At the same time, the arrangement also makes at least part of the water pan 3 deviate from the air inlet 15 in the up-down direction, so that the resistance of the airflow passing through the water pan 3 is smaller, and the energy efficiency ratio of the air conditioner is higher.

[0037] Specifically, W can be 35°, 40°, 45° and 50°. One end of the evaporator 2 can be positioned on the base 11 of the shell 1 through the cooperation of the guide column and the guide hole, and the other end of the evaporator 2 is connected to the base 11 through a threaded member.

[0038] In some embodiments, the first air guide channel 131 is located behind the second air guide channel 132, the diameter of the first cross-flow fan 4 is D1, and the diameter of the second cross-flow fan 5 is D2, and D1>D2.

[0039] The arrangement makes the power of the first cross-flow fan 4 greater than the power of the second cross-flow fan 5, so as to ensure that the airflow speed in the first air guide channel 131 is not less than the airflow speed in the second air guide channel 132, thereby effectively avoiding the two airflows from being deflected backward at the air outlet 16 due to the pressure difference, and the airflow at the air outlet 16 can be deflected forward at a larger angle, further ensuring the air outlet distance of the air conditioner and the indoor air circulation efficiency.

[0040] Need to be explained, the length of the evaporator 2 corresponding to the lower end opening of the first air guide channel 131 is greater than the length of the evaporator 2 corresponding to the lower end opening of the second air guide channel 132.

[0041] In some embodiments, the minimum distance between the center axis of the first cross-flow fan 4 and the evaporator 2 is h1, and the minimum distance between the center axis of the second cross-flow fan 5 and the evaporator 2 is h2, wherein h1=h2, 12mm+D1 / 2≤h1≤30mm+D1 / 2.

[0042] The arrangement ensures that the first cross-flow fan 4 and the second cross-flow fan 5 have a large enough gas flow space with the evaporator 2, so as to give the incoming airflow at any position of the evaporator 2 a large enough suction force, effectively avoiding the stagnation of part of the incoming airflow after heat exchange in part of the evaporator 2, thereby affecting the cooling and heating efficiency of the air conditioner. At the same time, it also avoids that the distance between the first cross-flow fan 4 and the second cross-flow fan 5 and the evaporator 2 is too large to affect the installation of other parts of the air conditioner, and ensures the compact structure of the air conditioner.

[0043] Specifically, h1 can be the sum of half of D1 and any value of 12mm, 20mm and 30mm.

[0044] In some embodiments, as shown in Figure 1 the distance between the central axis of the first cross-flow fan 4 and the central axis of the second cross-flow fan 5 is H, where 15mm+(D1+D2) / 2≤H≤30mm+(D1+D2) / 2.

[0045] That is, the minimum distance between the first cross-flow fan 4 and the second cross-flow fan 5 is between 15mm and 30mm, which on the one hand further avoids the two from blowing wind together, ensures the respective air volume, and on the other hand also avoids the distance between the first cross-flow fan 4 and the second cross-flow fan 5 being too large to affect the installation of other components of the air conditioner, ensuring the compact structure of the air conditioner.

[0046] Specifically, the minimum distance between the first cross-flow fan 4 and the second cross-flow fan 5 can be 15mm, 20mm, 25mm and 30mm.

[0047] In some embodiments, the upper edge of the first air guide channel 131 and the upper edge of the second air guide channel 132 are both spaced apart from the top surface of the shell 1. That is, the air flow out of the first air guide channel 131 and the air flow out of the second air guide channel 132 will first converge in the first chamber 13 before being discharged from the air outlet 16, thereby effectively ensuring the stability of the air outlet direction of the air conditioner to have a greater air outlet distance.

[0048] Specifically, the distance between the upper edge of the first air guide channel 131 and the top surface of the shell 1 is equal to the difference between the distance between the central axis of the second cross-flow fan 5 and the top surface of the shell 1 and the radius of the second cross-flow fan 5.

[0049] In some embodiments, the width of the first air guide channel 131 at the upper edge is h3, the width of the second air guide channel 132 at the upper edge is h4, and h3 / h4>D1 / D2.

[0050] That is, when the power of the first cross-flow fan 4 is greater than the power of the second cross-flow fan 5, the first air guide channel 131 is further widened in design, further ensuring that the first air guide channel 131 has a greater air volume while also ensuring that the first air guide channel 131 and the second air guide channel 132 have substantially the same air outlet speed, thereby ensuring that they do not easily blow backward to the wall surface after converging to cause air volume loss.

[0051] In some embodiments, as shown in Figure 1 and Figure 2As shown, the shell 1 comprises a base 11 and a front panel 12, the shell 1, the front panel 12 and the evaporator 2 jointly enclose a first chamber 13 and a second chamber 14, and the air inlet 15 is arranged on the lower side of the base 11.

[0052] That is, the air inlet 15 is formed on the bottom surface of the base 11, and the incoming air flow enters the second chamber 14 in a vertical upward direction, so that the path of the incoming air flow in the second chamber 14 is longer, and the incoming air flow can be more fully exchanged with each region of the evaporator 2 under the guidance of the evaporator 2.

[0053] Specifically, the upper end of the evaporator 2 abuts against the front panel 12, and the lower end of the evaporator 2 is inclined downward rearward relative to the upper end and abuts against the base 11.

[0054] In some embodiments, as shown in Figure 1 and Figure 2 shown, the base 11 is provided with a water collecting tray 3, the water collecting tray 3 is located below the lower edge of the evaporator 2, and the inner surface of the second chamber 14 comprises a first side surface 141 arranged on the base 11, the first side surface 141 is opposite to the front panel 12 along the width direction of the base 11, the water collecting tray 3 abuts against the first side surface 141, or the water collecting tray 3 is closer to the first side surface 141 than the front panel 12.

[0055] This arrangement makes at least part of the water collecting tray 3 deviate from the air inlet 15 in the up-down direction, so that the resistance of the incoming air flow passing through the water collecting tray 3 is smaller, and the energy efficiency ratio of the air conditioner is higher. At the same time, the rear upper edge of the water collecting tray 3 can abut against the first side surface 141, thereby being able to collect the condensed water from the base 11, so as to further reduce the probability of the condensed water dropping to the outside.

[0056] Specifically, the water collecting tray 3 is connected to the base 11 through a threaded member at both ends thereof in the left-right direction, and meanwhile, the water collecting tray 3 can also be clamped with the base 11 to ensure the positional reliability therebetween.
