DETAILED DESCRIPTION

[0025] The embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below by reference to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0026] The embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below by reference to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application. Figures 1-6The air conditioner according to the embodiment of the present application is described.

[0027] The air conditioner according to the embodiment of the present application comprises a shell 1, an evaporator 2 and a fan 3. The shell 1 is provided with a left air inlet 11, a right air inlet 12 and a top air outlet 13. The left air inlet 11 is arranged on the left side surface of the shell 1, the right air inlet 12 is arranged on the right side surface of the shell 1, and the top air outlet 13 is arranged on the top of the shell 1. The evaporator 2 is installed in the shell 1. The inner cavity of the shell 1 comprises a first chamber 18 above the evaporator 2 and a second chamber 19 below the evaporator 2. The top air outlet 13 is communicated with the first chamber 18, and the left air inlet 11 and the right air inlet 12 are both communicated with the second chamber 19. The fan 3 is installed in the first chamber 18.

[0028] According to the air conditioner of the present application, the left air inlet 11 and the right air inlet 12 are arranged on the left side surface and the right side surface of the shell 1 respectively, so that the evaporator 2 installed in the shell 1 can extend along the width direction of the shell 1. Compared with the evaporator extending along the length direction of the shell in the related art, the evaporator 2 of the present embodiment can occupy more space in the inner cavity of the shell 1 without exceeding the profile of the inner cavity of the shell 1, so as to have a larger heat exchange area and effectively improve the refrigeration and heating efficiency of the air conditioner. In addition, the top air outlet 13 is arranged on the top of the shell 1, which effectively solves the problem of rapid sinking of the air flow, and further effectively improves the air outlet distance of the air conditioner and the indoor air circulation efficiency.

[0029] 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.

[0030] In some embodiments, as shown in Figure 5 The shell 1 is further provided with a first lower air inlet 14 and a second lower air inlet 15. The first lower air inlet 14 and the second lower air inlet 15 are both communicated with the second chamber 19, and the first lower air inlet 14 and the second lower air inlet 15 are both arranged on the bottom surface of the shell 1 and are arranged in the length direction of the shell 1.

[0031] The arrangement of the first lower air inlet 14 and the second lower air inlet 15 further increases the air inlet area of the air conditioner, and the air flow in three directions can form more uniform air flow distribution on the surface of the evaporator 2 when passing through the evaporator 2. The heat exchange between the evaporator 2 and the air flow is more sufficient, the heat exchange efficiency of the evaporator 2 is higher, and the refrigeration and heating efficiency of the air conditioner is higher.

[0032] Specifically, the left air inlet 11 and the right air inlet 12 extend downward to the bottom plate of the shell 1, and the first lower air inlet 14 and the second lower air inlet 15 are respectively adjacent to the two ends of the length direction of the bottom plate of the shell 1.

[0033] In some embodiments, on the projection plane perpendicular to the width direction of the housing 1, the projected outer contour of the evaporator 2 is a U-shape or W-shape with the opening facing upwards.

[0034] The evaporator 2, with this shape, fits the inner cavity contour of the shell 1 better, which can have a larger heat exchange area and also facilitates more thorough heat exchange between the air intake airflow from the left air inlet 11, the right air inlet 12, the first lower air inlet 14 and the second lower air inlet 15 and the evaporator 2, thereby further improving the cooling and heating efficiency of the air conditioner.

[0035] like Figure 5 As shown, the projected outer contour of evaporator 2 is a U-shape with the opening facing upwards. Figure 6 As shown, the projected outer contour of the evaporator 2 is a W shape with the opening facing upwards. At this time, the evaporator 2 has two lowest points, and a water receiving tray 4 is provided below each of the two lowest points.

[0036] In some embodiments, such as Figure 5 The evaporator 2 includes a first straight segment 21, an arc segment 22, and a second straight segment 23 connected sequentially along the length of the shell 1. The middle part of the arc segment 22 bends downward relative to the first straight segment 21 and the second straight segment 23. The distance between the first straight segment 21 and the second straight segment 23 along the length of the shell 1 gradually increases from bottom to top. A water receiving tray 4 is installed in the second chamber 19, and the water receiving tray 4 is located below the arc segment 22.

[0037] That is, both the first straight segment 21 and the second straight segment 23 are inclined plate-like structures at an angle to the horizontal direction. This allows the evaporator 2 to guide and organize the airflow as it passes through the evaporator, ensuring a more even flow across its surface. This guarantees that all parts of the evaporator 2 can fully participate in heat exchange, preventing uneven heat exchange that could affect its efficiency. Furthermore, the inclined first straight segment 21 and the second straight segment 23 facilitate the flow of condensate along the inclined surface to the curved segment 22 and then to the drip tray 4, effectively preventing water accumulation inside the evaporator 2 and reducing the potential for bacteria and mold growth that could affect air conditioning operation and indoor air quality. Simultaneously, this design also positions the drip tray 4 away from the air inlet in both left-right and front-back directions, resulting in a higher energy efficiency ratio for the air conditioner.

[0038] Specifically, the first straight line segment 21 and the second straight line segment 23 are mirror-symmetrically arranged with respect to the first reference plane, which is a vertical plane perpendicular to the length direction of the shell 1. The arc segment 22 is also mirror-symmetrically arranged with respect to the first reference plane.

[0039] In some embodiments, such as Figure 5As shown, the first straight section 21 and the second straight section 23 are both at an angle W1 with the horizontal plane, and the circular center angle of the arc section 22 on the two opposite arc surfaces of the height direction of the shell 1 is W2, wherein 20°≤W1≤35°, and / or 35°≤W2≤55°.

[0040] At this time, the air flow from the left air inlet 11 and the first lower air inlet 14 can be more fully heat-exchanged with the first straight section 21 when reaching the first straight section 21, and the air flow from the right air inlet 12 and the second lower air inlet 15 can be more fully heat-exchanged with the second straight section 23 when reaching the second straight section 23. It also facilitates the sufficient heat exchange between the air flow and the arc section 22 under the guidance of the first straight section 21 and the second straight section 23, and the resistance caused by the evaporator 2 to the air flow is smaller, the air volume of the air conditioner is higher, and the refrigeration and heating efficiency is higher.

[0041] Specifically, W1 can be 20°, 25°, 30°, and 35°, and W2 can be 35°, 40°, 45°, 50°, and 55°.

[0042] In some embodiments, as shown in Figure 5 As shown, the first straight section 21 and the second straight section 23 are higher than the upper edge of each of the left air inlet 11 and the right air inlet 12 on the two opposite edges of the length direction of the shell 1.

[0043] This setting effectively reduces the probability that the air flow from the left air inlet 11 and the right air inlet 12 does not pass through heat exchange and is directly blown into the second chamber 19 and is directly blown to the indoor through the top air outlet 13, further improving the heating and refrigeration efficiency of the air conditioner.

[0044] In some embodiments, as shown in Figure 5 As shown, the inner surface of the inner cavity of the shell 1 includes a first side and a second side opposite in the length direction of the shell 1, the minimum distance between the first side and the first straight section 21 in the length direction of the shell 1 is D1, and the minimum distance between the second side and the second straight section 23 in the length direction of the shell 1 is D2, wherein D1=D2, 20mm≤D1≤65mm.

[0045] This setting allows the air flow on the left and right sides to smoothly enter the evaporator 2 at a relatively gentle angle, and form a more uniform air flow distribution on the surface of the evaporator 2 in the process, further improving the heat exchange efficiency of the evaporator 2, and the refrigeration and heating efficiency of the air conditioner is higher.

[0046] Specifically, the left air inlet 11 and the right air inlet 12 are mirror-symmetrically arranged relative to the first reference plane, and D1 can be 20mm, 30mm, 40mm, 50mm, and 65mm.

[0047] In some embodiments, as shown in Figure 4As shown, the water pan 4 has a length dimension L1 in the length direction of the shell 1, the first straight section 21 and the second straight section 23 are located at two opposite sides of the length direction of the shell 1, and the distance between the two straight sections in the length direction of the shell 1 is L2. The fan 3 is a cross-flow fan, and the length of the fan wheel of the fan 3 is L3. In this embodiment, 0.3*L2≤L1≤0.4*L2, and / or 50mm≤L2-L3≤80mm.

[0048] By setting 0.3*L2≤L1≤0.4*L2, the water pan 4 has sufficient water receiving area, which effectively reduces the water leakage probability of the air conditioner, and also avoids the size being too large to increase the manufacturing cost and occupy the area of the first lower air inlet 14 and the second lower air inlet 15. By setting 50mm≤L2-L3≤80mm, on the one hand, the fan 3 has greater power, so that the air conditioner has greater air volume, and on the other hand, the size of the fan 3 is not too large to occupy the installation of other components in the original position in the shell 1.

[0049] Specifically, L1 can be 0.3 times, 0.35 times and 0.4 times of L2, and the difference between L2 and L3 can be 50mm, 60mm, 70mm and 80mm.

[0050] In some embodiments, the distance between the plane where the edge of the left air inlet 11 is located and the plane where the edge of the right air inlet 12 is located in the length direction of the shell 1 gradually increases from bottom to top, and the plane where the edge of the left air inlet 11 is located and the plane where the edge of the right air inlet 12 is located are both at an angle W3 with the length direction of the shell 1, wherein 50°≤W3≤70°.

[0051] That is, the length of the shell 1 at the positions of the left air inlet 11 and the right air inlet 12 is wide at the bottom and narrow at the top, which can guide the air flow to some extent and ensure that the air flow blows obliquely upward to the evaporator 2, thereby further improving the heat exchange efficiency between the air flow and the evaporator 2, and improving the appearance of the air conditioner.

[0052] Specifically, the left air inlet 11, the right air inlet 12, the first lower air inlet 14 and the second lower air inlet 15 are each provided with an air inlet grille. The shell 1 includes a base 16 and a front panel 17 connected to each other, and the left air inlet 11, the right air inlet 12, the first lower air inlet 14 and the second lower air inlet 15 are formed on the base 16, and the air inlet grille is installed on the base 16.

[0053] In some embodiments, as shown in FIG. 6, the left air inlet 11 and the right air inlet 12 are located at the left side and the right side of the front panel 17, respectively, and the first lower air inlet 14 and the second lower air inlet 15 are located at the bottom of the front panel 17. Figure 3As shown, the ejection air outlet 13 is arranged on the front side of the shell 1, the upper edge and the lower edge of the ejection air outlet 13 are spaced apart by h1 in the height direction of the shell 1, the center axis of the fan 3 is higher than the lower edge of the ejection air outlet 13, and the center axis of the fan 3 is spaced apart from the lower edge of the ejection air outlet 13 by h2 in the height direction of the shell 1, and 0.2*h1<=h2<=0.3*h1.

[0054] The arrangement increases the air outlet area of the ejection air outlet 13, effectively shortens the air outlet path of the air flow in the second chamber 19, effectively reduces the loss of the air flow in the shell 1, and increases the air outlet volume and the air outlet distance of the air conditioner.

[0055] Specifically, h2 can be 0.2 times, 0.25 times and 0.3 times of h1.
