[0020] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] The following is combined Figure 1 This invention describes an air conditioner according to an embodiment of the present invention.

[0022] The air conditioner of this embodiment includes a base 1, a front panel 2, an evaporator 3, and a cross-flow fan 4. The base 1 and the front panel 2 are connected and form a mounting cavity, an air inlet 12, and an air outlet 13. The air inlet 12 and the air outlet 13 are both connected to the mounting cavity and are located on the front and upper sides of the mounting cavity, respectively. The mounting cavity includes a water collection groove 11 formed on the bottom of the base 1. The evaporator 3 is installed inside the mounting cavity. On a projection plane perpendicular to the length direction of the base 1, the outer outline of the evaporator 3 is strip-shaped. The extension direction of the evaporator 3's projection forms an angle with the horizontal plane. The lower end of the evaporator 3 is located above or inside the water collection groove 11. The cross-flow fan 4 is installed inside the mounting cavity and is located on the side of the evaporator 3 opposite to the air inlet 12.

[0023] According to the embodiment of this utility model, by placing the air outlet 13 on the front side of the mounting cavity, the problem of rapid downward movement of the airflow is effectively solved, thereby effectively increasing the air outlet distance of the air conditioner and improving the indoor air circulation efficiency. By directly forming the water collection tray 11 on the base 1, the condensate on the evaporator 3 is ensured to be drained to the outside, while also reducing the arrangement of the water collection tray. At this time, the evaporator 3 can be designed to be larger in size, so as to have a larger heat exchange area, resulting in high cooling and heating efficiency of the air conditioner.

[0024] It should be noted that the base 1 has an air inlet 12 and an air outlet 13 formed on it, and the vertical, horizontal, and back-to-front directions of the base 1 are consistent with the vertical, horizontal, and back-to-front directions of the air conditioner after actual installation. Figure 1 As shown, the lower end of the evaporator 3 is located inside the water receiving tank 11, thus providing a larger heat exchange area.

[0025] In some embodiments, as shown in FIG. 1, the width of the air inlet 12 is L1, the width of the evaporator 3 is L2, and the distance between the lower edge of the evaporator 3 and the central axis of the cross-flow fan 4 in the width direction of the evaporator 3 is L3, wherein 220mm≤L1≤280mm, 20mm≤L2-L1≤60mm, and / or 0.35*L2≤L3≤0.45*L2. Figure 1 As shown in FIG. 1, in the projection plane perpendicular to the length direction of the base 1, the extension direction of the projection of the evaporator 3 is consistent with the extension direction of the projection of the front panel 2, and the extension direction of the projection of the evaporator 3 is at an angle W1 with the height direction of the base 1, wherein 8°≤W1≤15°.

[0026] That is, the evaporator 3 is in the form of an inclined plate at an angle with the horizontal direction, so that when the air flow passes through the evaporator 3, the evaporator 3 can guide and comb the passing air flow, so that the air flow can flow more uniformly over the surface of the evaporator 3, ensuring that all parts of the evaporator 3 can fully participate in heat exchange, avoiding local uneven heat exchange and affecting the heat exchange efficiency of the evaporator 3. In addition, the inclined evaporator 3 also facilitates the flow of condensed water along the inclined surface to the water collecting groove 11, effectively preventing water accumulation inside the evaporator 3, reducing the risk of bacteria, mold, and other factors affecting air conditioner use and indoor air quality. In addition, the inclined arrangement of the front panel 2 makes the outer contour shape of the air conditioner closer to the outer contour shape of the air conditioner in the related art, with high aesthetic appearance.

[0027] Specifically, the width of the outer contour of the air conditioner gradually decreases from top to bottom, and the angle W1 between the evaporator 3 and the vertical direction can be 8°, 10°, 12°, and 15°.

[0028] In some embodiments, the width of the air inlet 12 is L1, the width of the evaporator 3 is L2, and the distance between the lower edge of the evaporator 3 and the central axis of the cross-flow fan 4 in the width direction of the evaporator 3 is L3, wherein 220mm≤L1≤280mm, 20mm≤L2-L1≤60mm, and / or 0.35*L2≤L3≤0.45*L2.

[0029] By setting 220mm≤L1≤280mm, it is ensured that the air conditioner has a large enough air inlet area, so that the air conditioner has a larger air volume. By setting 20mm≤L2-L1≤60mm, the evaporator 3 has a larger heat exchange area, so that the air conditioner has higher cooling and heating efficiency. By setting 0.35*L2≤L3≤0.45*L2, it is ensured that the evaporator 3 can provide sufficient suction to the lower end region of the evaporator 3, so as to effectively prevent the heat exchange air flow from stagnating at the lower end of the evaporator 3 and affecting the cooling and heating efficiency of the air conditioner.

[0030] Specifically, as shown in FIG. 1, the width of the air inlet 12 can be 220mm, 240mm, 260mm, and 280mm, the width of the evaporator 3 is the distance between the upper edge and the lower edge of the front side of the evaporator 3, L2>L1, and the difference between the two can be 20mm, 40mm, and 60mm. L3 can be 0.35 times, 0.4 times, and 0.45 times of L2. Figure 1 Specifically, as shown in FIG. 1, the width of the air inlet 12 can be 220mm, 240mm, 260mm, and 280mm, the width of the evaporator 3 is the distance between the upper edge and the lower edge of the front side of the evaporator 3, L2>L1, and the difference between the two can be 20mm, 40mm, and 60mm. L3 can be 0.35 times, 0.4 times, and 0.45 times of L2.

[0031] In some embodiments, as shown in FIG. 1, the radius of the cross-flow fan 4 is R, and the minimum distance between the central axis of the cross-flow fan 4 and the evaporator 3 is L4, wherein 14mm≤L4-R≤20mm. Figure 1

[0032] That is, the minimum distance between the cross-flow fan 4 and the evaporator 3 is between 14mm and 20mm, so that there is a large enough gas flow space between the cross-flow fan 4 and the evaporator 3 to give the air inlet gas flow at any position of the evaporator 3 a large enough suction force, effectively avoiding the stagnation of part of the air inlet gas flow after heat exchange in part of the evaporator 3 to affect the cooling and heating efficiency of the air conditioner. At the same time, it also avoids the distance between the cross-flow fan 4 and the evaporator 3 being too large to affect the installation of other parts of the air conditioner, ensuring the compact structure of the air conditioner.

[0033] Specifically, the difference between L4 and R can be 14mm, 16mm, 18mm and 20mm.

[0034] In some embodiments, as shown in FIG. 1, the air inlet grille 5 is installed at the air inlet 12, and in the projection plane perpendicular to the length direction of the base 1, the extension direction of the projection of the air inlet grille 5 is consistent with the extension direction of the projection of the evaporator 3, and the distance between the air inlet grille 5 and the evaporator 3 is L5, wherein 8mm≤L5≤15mm. Figure 1 This setting ensures that the air inlet gas flow passing through the air inlet grille 5 has enough diffusion space to facilitate the heat exchange between the air inlet gas flow and each region of the evaporator 3, further ensuring the cooling and heating efficiency of the air conditioner. At the same time, it also makes the evaporator 3 arranged reasonably in the inner cavity of the air conditioner, without occupying other parts of the air conditioner, and also effectively ensures the compact structure of the air conditioner.

[0035] Specifically, L5 can be 8mm, 11mm, 13mm and 15mm.

[0036] In some embodiments, the extension direction of the air inlet channel formed in the air inlet grille 5 forms an angle W2 with the horizontal plane, wherein 15°≤W2≤30°.

[0037] At this angle, the user can effectively avoid seeing the internal evaporator 3 through the air inlet grille 5, and the appearance of the air conditioner is more aesthetic.

[0038] Specifically, the extension direction of the air inlet channel formed by the air inlet grille 5 is consistent with the extension direction of the grille ribs of the air inlet grille 5, and W2 can be 15°, 20°, 25° and 30°.

[0039]

[0040] ​​In some embodiments, the installation cavity further comprises a diffuser air duct 14 in communication with the air outlet 13, an inner surface of the diffuser air duct 14 comprises a first side surface 141 and a second side surface 142 opposite in the front-rear direction, the first side surface 141 is located in front of the second side surface 142, and a distance between an upper edge and a lower edge of the first side surface 141 is L6, where 120mm≤L6≤150mm.

[0041] This arrangement makes the diffuser air duct 14 have a greater diffuser distance, so that the air outlet 13 has a greater air outlet area, thereby making the air conditioner have a greater air volume, and the user experience is better.

[0042] Specifically, the first side surface 141 and the second side surface 142 extend forward in a direction close to the air outlet 13, the width of the diffuser air duct 14 gradually increases in the direction close to the air outlet 13, the lower edge of the first side surface 141 is connected to the upper edge of the air guide surface of the volute tongue, and L6 can be 120mm, 135mm and 150mm.

[0043] In some embodiments, in the direction close to the air outlet 13, the distance between the first side surface 141 and the second side surface 142 in the front-rear direction gradually increases, and the first side surface 141 and the second side surface 142 form an angle W3, where 17°≤W3≤22°. Thus, on the basis of a certain length of the diffuser air duct 14, the width of the air outlet 13 is greater, and the air conditioner has a greater air volume, so that the indoor air circulation efficiency is higher.

[0044] Specifically, W3 can be 17°, 20° and 22°.

[0045] In some embodiments, as shown in Figure 1 the minimum width of the bottom of the base 1 is L7, and the minimum width of the water collecting groove 11 is L8, where 25mm≤L7-L8≤40mm.

[0046] This arrangement not only ensures that the water collecting groove 11 has a large enough width to better ensure the reliability of the condensate water receiving, but also effectively ensures that the bottom of the base 1 has sufficient structural strength, effectively ensuring the service life of the air conditioner.

[0047] Specifically, the difference between L7 and L8 can be 25mm, 30mm, 35mm and 40mm.

[0048] In some embodiments, the maximum depth of the water collecting groove 11 is H1, and the bottom surface of the water collecting groove 11 forms an angle W4 with the length direction of the base 1, where 15mm≤H1≤25mm, and 1°≤W4≤3°.

[0049] The setting guarantees that the water receiving groove 11 has a larger water receiving space, and facilitates guiding the condensed water in the water receiving groove 11 to the lowest end, so as to be discharged to the outdoor more quickly, and effectively avoid breeding of bacteria, mold and the like due to long-time residence of the condensed water in the water receiving groove 11.

[0050] Specifically, H1 can be 15mm, 20mm and 25mm, and W4 can be 1°, 2° and 3°.
