[0019] The embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0020] The air conditioner according to the embodiments of the present application is described below in conjunction with Figure 1

[0021] The air conditioner according to the embodiments of the present application comprises an indoor unit body 1, an evaporator 3 and a water pan 2. The indoor unit body 1 is internally provided with a supply air passage 13, the evaporator 3 and the water pan 2 are both arranged in the supply air passage 13, the water pan 2 is located at the bottom of the evaporator 3, the water pan 2 is formed with a water receiving groove 25, and the distance between the lowest point of the inner wall surface of the water receiving groove 25 and the lowest point of the evaporator 3 in the height direction (such as the up-down direction) of the water pan 2 is a, wherein 5mm≤a≤20mm. Figure 1

[0022] According to the air conditioner according to the embodiments of the present application, the distance between the lowest point of the inner wall surface of the water receiving groove 25 and the lowest point of the evaporator 3 in the up-down direction is between 5mm and 20mm, and on the basis of the maximum size of the water pan 2 in the front-rear direction being appropriately set to ensure that the airflow smoothly passes through the front-rear side supply air space of the water pan 2, on the one hand, the water receiving groove 25 has sufficient water receiving volume, and on the other hand, the water pan 2 is effectively prevented from being too short in the downward distance to the air inlet hole 121 to block the air inlet hole 121 and increase the air resistance when the airflow enters the air inlet hole 121, thereby effectively ensuring the air supply efficiency of the air conditioner.

[0023] It should be noted that the distance between the lowest point of the inner wall surface of the water receiving groove 25 and the lowest point of the evaporator 3 in the height direction of the water pan 2 can be 5mm, 10mm, 15mm and 20mm. The width of the water receiving groove 25 gradually increases from bottom to top. In addition, the above distance also ensures that the condensate water droplets falling on the evaporator 3 will not splash when falling into the water receiving groove 25 due to the distance being too large. The indoor unit body 1 comprises a base 11 and a middle frame 12, the base 11 and the middle frame 12 are connected, the base 11 and the middle frame 12 surround the formed supply air passage 13, the middle frame 12 is provided with an air inlet hole 121, the air inlet hole 121 is in communication with the supply air passage 13 and is located below the supply air passage 13. The middle frame 12 comprises a front panel and a bottom plate connected to each other, the bottom plate is provided with the air inlet hole 121, and the air inlet hole 121 is detachably installed with an air inlet grille.

[0024] In some embodiments, as shown in Figure 1 the lower end of the evaporator 3 is located in the water receiving groove 25, and the distance between the highest point of the inner wall surface of the water receiving groove 25 and the lowest point of the evaporator 3 in the height direction of the water pan 2 is b, wherein 10mm≤b≤30mm. ​​

[0025] This setting further increases the depth of the water receiving trough 25, further ensuring the water receiving reliability of the water receiving trough 25, and at the same time will not increase the distance between the lowest point of the outer wall of the water receiving tray 2 and the lower surface of the inner machine body 1, thereby effectively ensuring the smoothness of the air flow entering the air inlet hole 121, and the air supply efficiency of the air conditioner is higher.

[0026] Specifically, the distance between the highest point of the inner wall surface of the water receiving groove 25 and the lowest point of the evaporator 3 in the height direction of the water receiving tray 2 can be 10 mm, 20 mm, or 30 mm.

[0027] In some embodiments, 0.1≤a / b≤2.

[0028] This arrangement, while ensuring that the water receiving capacity of the water receiving tank 25 remains unchanged, can not only extend at least partially the lower end of the evaporator 3 into the water receiving tank 25 to increase the distance between the lowest point of the outer wall of the water receiving tray 2 and the lower surface of the inner machine body 1, but also ensure that the water receiving tank 25 can fully receive the condensed water dripping from the evaporator 3.

[0029] In some embodiments, there are two evaporators 3, the lower ends of the two evaporators 3 are connected and angled with each other, and on the projection plane perpendicular to the height direction of the water receiving tray 2, the projection of the lower end surfaces of the two evaporators 3 coincides with the projection of the water receiving trough 25.

[0030] This ensures that when the condensed water on the two evaporators 3 drips from the lower end surface of the evaporator 3, it can be received by the water receiving groove 25, effectively preventing the condensed water from directly dripping outside the water receiving tray 2 and flowing out from the air inlet hole 121, providing a better user experience.

[0031] In some embodiments, as Figure 1 As shown, the width of the water receiving trough 25 gradually increases from bottom to top.

[0032] On the basis that at least part of the lower end of the evaporator 3 is located in the water receiving tank 25, the two opposite side surfaces of the water receiving tank 25 along its width are arranged to be inclined surfaces. Therefore, when the two side surfaces receive the condensed water dripping from the evaporator 3, the condensed water will be automatically guided to the bottom of the water receiving tank 25 along the side surfaces, further avoiding the condensed water dripping at high speed to the bottom of the water receiving tank 25 and causing liquid splashing.

[0033] Specifically, the water receiving groove 25 is generally a V-shaped groove, and the inner wall surface of the water receiving groove 25 is an arc surface with a downward depression in the middle.

[0034] In some embodiments, the lower surface of the inner machine body 1 is provided with an air inlet hole 121 connected to the air supply channel 13, and the minimum distance between the lower surface of the inner machine body 1 and the outer wall of the water receiving tray 2 in the height direction of the water receiving tray 2 is h, where 30mm≤h≤60mm.

[0035] This arrangement prevents the water collecting pan 2 from being too close to the air inlet grille in the air inlet hole 121 and increasing the air inlet resistance at the air inlet grille, and prevents the water collecting pan 2 from being too close to the evaporator 3 and affecting its water collection capacity.

[0036] Specifically, the distance between the lower surface of the inner machine body 1 and the lowest point of the outer wall of the water receiving tray 2 can be 30 mm, 45 mm, and 60 mm.

[0037] In some embodiments, the outer wall surface of the water receiving tray 2 includes a first surface 21 and a second surface 22 opposite to each other along the width direction of the water receiving tray 2. On the projection surface perpendicular to the width direction of the water receiving tray 2, the projection contour of the first surface 21 is a first fold line segment, and the projection contour of the second surface 22 is a second fold line segment. The lowest line segment in the first fold line segment and the lowest line segment in the second fold line segment are connected to form a downwardly concave arc.

[0038] That is, the lower end of the first fold line segment and the lower end of the second fold line segment are directly connected. At this time, the bottom surface of the water receiving tray 2 is a downwardly concave arc surface, and then when the airflow blows from bottom to top to the bottom surface of the water receiving tray 2, it can be better guided to the front and back sides of the water receiving tray 2 by the first surface 21 and the second surface 22 respectively, further reducing the probability of the airflow forming vortices on the bottom surface of the water receiving tray 2, and the air supply uniformity and air supply efficiency of the air conditioner are higher.

[0039] Specifically, the lower end of the first arc segment and the lower end of the second arc segment are both the lowest points of the outer wall of the water receiving tray 2, and the tangents of the two at the lower ends coincide, that is, the first arc segment and the second arc segment are smoothly connected.

[0040] It should be noted that in this embodiment, the lowest segment of either the first fold line segment or the second fold line segment can be set as a straight line segment, which also has the advantages of uniform air supply and high air supply efficiency of the air conditioner.

[0041] In some embodiments, as Figure 1 As shown, the air supply channel 13 includes a first channel 131 and a second channel 132 which are respectively arranged on opposite sides of the water receiving tray 2 in the width direction of the water receiving tray 2. The first channel 131 and the second channel 132 are both connected to the air inlet hole 121, and the width of at least one of the first channel 131 and the second channel 132 decreases sequentially from bottom to top.

[0042] Therefore, when the airflow passes upward through the air supply space on the front and rear sides of the water receiving tray 2, it can guide the airflow while effectively increasing its airflow velocity, thereby effectively ensuring the air supply efficiency.

[0043] In some embodiments, the minimum width of the first channel 131 is c, and the minimum width of the second channel 132 is d, wherein 25 mm ≤ c ≤ 75 mm, and / or 15 mm ≤ d ≤ 40 mm.

[0044] By setting the minimum width of the first channel 131 between 25mm and 75mm, and the minimum width of the second channel 132 between 15mm and 40mm, on the one hand, the width of the air supply space in front of and behind the water pan 2 is prevented from being too small to increase the air resistance, and on the other hand, the width of the water pan 2 is prevented from being too large to reduce the width of the water pan 2, thereby effectively ensuring the water receiving reliability of the water pan 2.

[0045] Specifically, the minimum width of the first channel 131 can be 25mm, 50mm and 75mm, and the minimum width of the second channel 132 can be 15mm, 30mm and 40mm.
