[0019] Embodiments of the present application will be 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 will be described below in conjunction with Figure 1

[0021] The air conditioner according to the embodiments of the present application comprises an inner machine body 1 and a water receiving tray 2. The inner machine body 1 is provided with an air supply channel 13 and an air inlet hole 121 in communication. The air inlet hole 121 is located below the air supply channel 13 and extends downward to the lower surface of the inner machine body 1, and the water receiving tray 2 is arranged in the air supply channel 13. The maximum dimension of the water receiving tray 2 in the width direction (such as the front-rear direction) of the water receiving tray 2 is a, and the minimum dimension of the air inlet hole 121 in the width direction of the water receiving tray 2 is b, wherein a < b. Figure 1

[0022] According to the air conditioner according to the embodiments of the present application, by setting the minimum width of the air inlet hole 121 to be greater than the maximum width of the water receiving tray 2, while ensuring that the width of the water receiving tray 2 is appropriate to facilitate the water receiving reliability thereof, the initial path of the airflow entering the air supply channel 13 from the air inlet hole 121 is also wider, and the airflow can more smoothly pass through the space on both sides of the water receiving tray 2 when passing through the water receiving tray 2, the air supply resistance of the airflow is lower, the air supply amount is greater, and the air supply efficiency is higher.

[0023] Specifically, the water receiving tray 2 is spaced apart from the inner wall surface of the air supply channel 13 in the front-rear direction, and the minimum width of the air supply channel 13 is greater than the maximum width of the air inlet hole 121.

[0024] In some embodiments, as shown in Figure 1 the ratio of a to b is 0.5-0.8, and / or 65mm ≤ a ≤ 95mm, and / or 80mm ≤ b ≤ 190mm.

[0025] ​​The above arrangement avoids the water receiving tray 2 being too narrow to reliably receive water, and avoids the water receiving tray 2 being too wide to cause the width of the air supply space on the front and back sides of the water receiving tray 2 to be too small, thereby increasing the air inlet resistance. In addition, the width of the air inlet hole 121 is set to be between 80 mm and 190 mm, which on the one hand avoids the width of the air inlet hole 121 being too small to affect the air inlet efficiency, and on the other hand avoids the width of the air inlet hole 121 being too large to cause the width of the lower end of the air conditioner to be too large, thereby affecting the aesthetic appearance of the air conditioner.

[0026] Specifically, the ratio of a to b can be 0.5, 0.65, and 0.8, the maximum width of the water receiving tray 2 can be 65 mm, 80 mm, and 95 mm, and the minimum width of the air inlet hole 121 can be 80 mm, 135 mm, and 190 mm. The width of the air inlet hole 121 at each position in the extension direction thereof is equal.

[0027] In some embodiments, the minimum distance between the lower surface of the indoor unit body 1 and the outer wall surface of the water receiving tray 2 in the height direction of the water receiving tray 2 is h, where 30 mm≤h≤60 mm.

[0028] This arrangement on the one hand avoids the water receiving tray 2 being too close to the air inlet grille in the air inlet hole 121 to increase the air inlet resistance of the airflow at the air inlet grille, and on the other hand avoids the water receiving tray 2 being too close to the evaporator upwards to affect the water receiving amount.

[0029] Specifically, the distance between the lower surface of the indoor unit body 1 and the lowest point of the outer wall surface of the water receiving tray 2 can be 30 mm, 45 mm, and 60 mm.

[0030] In some embodiments, as shown in Figure 1 the outer wall surface of the water receiving tray 2 includes a first face 21 and a second face 22 opposite in the width direction of the water receiving tray 2. In a projection plane perpendicular to the width direction of the water receiving tray 2, the projection profile of the first face 21 is a first broken line segment, and the projection profile of the second face 22 is a second broken line segment. The distance between the first broken line segment and the second broken line segment in the width direction of the water receiving tray 2 gradually increases from bottom to top.

[0031] Thus, each part of the first face 21 and the second face 22 is an inclined surface at an angle to the horizontal direction. Thus, when the airflow passes through the first face 21 and the second face 22 of the water receiving tray 2 from bottom to top, it is guided to the front and back sides of the water receiving tray 2 and is not easy to generate vortex on the outer wall surface of the water receiving tray 2, and the air supply resistance of the airflow is small.

[0032] In some embodiments, the lowest line segment in the first broken line segment and the lowest line segment in the second broken line segment are connected and form a downwardly concave arc line.

[0033] 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 pan 2 is a downwardly concave arc surface, and when the airflow is blown from bottom to top to the bottom surface of the water pan 2, the airflow can be better guided to the front and rear sides of the water pan 2 by the first surface 21 and the second surface 22 respectively, further reducing the probability of vortex formation of the airflow on the bottom surface of the water pan 2, and the air conditioner has higher air supply uniformity and air supply efficiency.

[0034] Need to be explained, this embodiment can also be set as a straight line segment in the lowermost position in any one of the first fold line segment and the second fold line segment, also has the advantages of high air supply uniformity and air supply efficiency of the air conditioner.

[0035] In some embodiments, the outer wall surface of the water pan 2 further includes a third surface 23 and a fourth surface 24 opposite along the width direction of the water pan 2, the third surface 23 and the fourth surface 24 are both vertical surfaces, the lower end of the third surface 23 is connected with the upper end of the first surface 21, and the lower end of the fourth surface 24 is connected with the upper end of the second surface 22, and the distance between the third surface 23 and the fourth surface 24 is a.

[0036] Therefore, on the basis of the certain size of the first surface 21 and the second surface 22 in the up-down direction, by setting the third surface 23 and the fourth surface 24 as vertical surfaces, the water pan 2 can form a water collecting groove 25 with a greater depth while effectively avoiding the maximum size of the water pan 2 in the front-rear direction being too large to affect the width of the air supply space on the front and rear sides of the water pan 2, so that the airflow passing through the air supply space on the side of the water pan 2 is smoother, and the air conditioner has higher air supply efficiency.

[0037] In some embodiments, as shown in Figure 1 the air supply channel 13 includes a first channel 131 and a second channel 132 arranged on opposite sides of the water pan 2 in the width direction of the water pan 2, the first channel 131 and the second channel 132 are both in communication with the air inlet hole 121, and the width of at least one of the first channel 131 and the second channel 132 gradually decreases from bottom to top.

[0038] Therefore, when the airflow passes through the air supply space on the front and rear sides of the water pan 2 upward, the airflow can be guided while its flow rate is effectively increased, thereby effectively ensuring the air supply efficiency.

[0039] 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 25mm≤c≤75mm, and / or 15mm≤d≤40mm.

[0040] 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, effectively ensuring the water receiving reliability of the water pan 2.

[0041] 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.

[0042] In some embodiments, two evaporators are arranged in the air supply channel 13, the lower ends of the two evaporators are connected and angled to each other, the water pan 2 is formed with a water receiving groove 25, and in the projection plane perpendicular to the height direction of the water pan 2, the projection of the lower end surface of the two evaporators coincides with the projection of the water receiving groove 25.

[0043] In this way, when the condensed water on the two evaporators drips from the lower end surface of the evaporator, it can be received by the water receiving groove 25, effectively preventing the condensed water from directly dripping outside the water pan 2 and flowing out through the air inlet hole 121, and the user experience is better.

[0044] The inner unit body 1 includes 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 air supply channel 13, and the middle frame 12 is provided with an air inlet hole 121. Among them, the middle frame 12 includes a front panel and a bottom plate connected, the bottom plate is provided with an air inlet hole 121, and the air inlet hole 121 is detachably installed with an air inlet grille.
