DETAILED DESCRIPTION

[0019] Embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below by way of example with reference to the accompanying drawings are intended to explain the present application, and should not be construed as limiting the present application.

[0020] The air conditioner according to an embodiment of the present application is described below with reference to the accompanying drawings. Figure 1

[0021] The air conditioner according to an embodiment of the present application includes a housing 1 and an evaporator. The housing 1 is provided with a first air inlet 13 and a second air inlet 14, which are respectively located on opposite sides of the housing 1 in the width direction (front-rear direction) of the housing 1. Figure 1 The evaporator is installed in the housing 1 and surrounds a V-shaped groove extending along the length direction (left-right direction of the air conditioner) of the housing 1. The opening of the V-shaped groove is inclined toward the first air inlet 13 or the second air inlet 14.

[0022] ​According to the air conditioner provided in the embodiment of the present application, the second air inlet 14 and the first air inlet 13 are arranged on the front and back sides of the shell 1 respectively, so that the air conditioner has a larger air inlet area and a wider air inlet direction. In addition, the opening of the V-shaped groove formed by the evaporator is inclined towards the first air inlet 13 or the second air inlet 14, so that the air inlet from the first air inlet 13 and the second air inlet 14 has a lower resistance when passing through the evaporator, the air flow and the heat exchange of each area of the evaporator are more sufficient, and the heating and cooling efficiency of the air conditioner is higher, and the user experience is higher.

[0023] 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 being actually installed. The first air inlet 13 and the second air inlet 14 are located at the bottom of the shell 1, and the top of the shell 1 is provided with an air outlet 15.

[0024] In some embodiments, the shell 1 comprises a base 11 and a front panel 12, the base 11 has a first side face 111 opposite to the front panel 12 along the width direction of the shell 1, at least part of the first air inlet 13 extends to the first side face 111, and the opening of the V-shaped groove is inclined towards the first air inlet 13.

[0025] That is, the opening of the V-shaped groove formed by the evaporator is inclined towards the back to be opposite to the wall surface. The setting makes the air flow from the first air inlet 13 have a lower resistance when passing through the evaporator, and the heat exchange efficiency with the evaporator is higher. At this time, the air inlet area of the first air inlet 13 can be set to be larger than that of the second air inlet 14, so as to effectively reduce the appearance degree of the air conditioner while ensuring the cooling and heating efficiency of the air conditioner.

[0026] Specifically, the first air inlet 13 is inclined downwards, that is, part of the first air inlet 13 extends to the bottom support seat 112 of the base 11.

[0027] In some embodiments, as shown in Figure 1 The angle between the plane where the outer edge of the first air inlet 13 is located and the first side face 111 is P1, wherein 25°≤P1≤50°.

[0028] The setting ensures that the first air inlet 13 and the wall surface have a larger air inlet area, so as to ensure that the external air can flow into the shell 1 smoothly, effectively ensure the air inlet amount of the air conditioner at the first air inlet 13, and effectively ensure the cooling and heating efficiency of the air conditioner.

[0029] Specifically, the angle between the plane where the outer edge of the first air inlet 13 is located and the first side face 111 can be 25°, 40° and 50°.

[0030] In some embodiments, as shown in Figure 1As shown, the evaporator comprises a first evaporator 2 and a second evaporator 3 arranged from bottom to top, the first evaporator 2 comprises a first linear section 21 and a first bending section 22 connected in sequence, the second evaporator 3 comprises a second linear section 31 and a second bending section 32 connected in sequence, the first linear section 21 and the second linear section 31 have the same extension direction and abut each other, and the first bending section 22 and the second bending section 32 surround a V-shaped groove.

[0031] By dividing the evaporator into the first evaporator 2 and the second evaporator 3, the structure of the first evaporator 2 and the second evaporator 3 is simpler, and the manufacturing cost is lower. Moreover, by arranging the first bending section 22 and the second bending section 32 to surround the V-shaped groove, the side surface of the V-shaped groove is a smooth arc surface, the side surface of the V-shaped groove is better for guiding the incoming air flow, the heat exchange between the incoming air flow and each area of the first evaporator 2 and the second evaporator 3 is more sufficient, and the heat exchange efficiency is higher.

[0032] Specifically, the first linear section 21 and the second linear section 31 extend obliquely upward to the front panel 12, and the free ends of the first bending section 22 and the second bending section 32 extend to the base 11 in opposite directions.

[0033] In some embodiments, as shown, Figure 1 The inner surface of the front panel 12 comprises a second side surface 121 and a third side surface 122, the second side surface 121 is located on the side of the first linear section 21 away from the second linear section 31, and the third side surface 122 is located on the side of the second linear section 31 away from the first linear section 21. The second side surface 121 is at an angle M1 with the extension direction of the first linear section 21, the third side surface 122 is at an angle M2 with the extension direction of the second linear section 31, and the two side surfaces of the first bending section 22 and the second bending section 32 opposite to each other are at an angle M3 at the intersection. Among them, 50°≤M1≤100°, and / or, 25°≤M2≤60°, and / or, 6°≤M3≤30°.

[0034] This arrangement makes the second side surface 121 and the third side surface 122 of the front panel 12 better for guiding the incoming air flow, and the incoming air flow can flow in and out of the first evaporator 2 and the second evaporator 3 more smoothly for heat exchange, and the heat exchange efficiency between the incoming air flow and the first evaporator 2 and the second evaporator 3 is higher.

[0035] Specifically, M1 can be 50°, 60°, 75°, 90°, and 100°. M2 can be 25°, 35°, 45°, and 60°. M3 can be 6°, 15°, 25°, and 30°.

[0036] In some embodiments, as shown, Figure 1As shown, the side of the first straight section 21 away from the second straight section 31 and the side of the first bending section 22 away from the second bending section 32 are at an intersection angle M4, and the side of the second straight section 31 away from the first straight section 21 and the side of the second bending section 32 away from the first bending section 22 are at an intersection angle M5, wherein 90°≤M4≤180°, and / or 90°≤M5≤180°.

[0037] This arrangement can make the space of the V-shaped groove larger, the air flow from the first air inlet 13 can pass through the first evaporator 2 and the second evaporator 3 more smoothly, and the condensed water on the first evaporator 2 and the second evaporator 3 can flow more smoothly to the lowest end of the corresponding evaporator to flow more smoothly into the water pan below.

[0038] Specifically, M4 can be 90°, 120°, 160°, and 180°, and M5 can be 90°, 120°, 160°, and 180°.

[0039] In some embodiments, the radius of curvature of the two sides of the first bending section 22 and the second bending section 32 away from each other is equal and is N, wherein 80mm≤N≤240mm.

[0040] This arrangement makes the air flow pass through the first evaporator 2 and the second evaporator 3 more smoothly at a relatively gentle angle, and in the process, a more uniform air flow distribution can be formed on the surface of the first evaporator 2 and the second evaporator 3, the first evaporator 2 and the second evaporator 3 can exchange heat with the air flow more fully, the heat exchange efficiency of the first evaporator 2 and the second evaporator 3 is higher, and the refrigeration and heating effect of the air conditioner is better.

[0041] Specifically, the radius of curvature of the two sides of the first bending section 22 and the second bending section 32 away from each other and the radius of curvature of the two sides opposite to each other are equal, and N can be 80mm, 120mm, 160mm, 200mm, and 240mm.

[0042] In some embodiments, the side of the first evaporator 2 away from the second evaporator 3 is provided with a fan 6, the maximum distance between the center of the fan 6 and the first bending section 22 is H1, the radius of the fan 6 is D1, and 7*D1 / 4≤H1≤5*D1 / 2.

[0043] This arrangement ensures that there is more space between the fan 6 and the first evaporator 2, which in turn makes the flow direction of the air flow after passing through the first evaporator 2 more stable and less likely to be disturbed to reduce the air volume of the air conditioner.

[0044] Specifically, the fan 6 is a cross-flow fan 6, and the size of H1 can be 7 / 4 times, 2 times, 2.3 times, and 2.5 times the size of D1.

[0045] In some embodiments, as shown in Figure 1 The base 11 includes a bottom support base 112 forming a bottom surface of the shell 1, a free end of the second bent section 32 extends downward to a top surface of the bottom support base 112, a first water pan 4 is mounted on a side of the bottom support base 112 facing the first air inlet 13, and a second water pan 5 is mounted on a side of the bottom support base 112 facing the second air inlet 14, and the first water pan 4 is located below a lowermost end of the first bent section 22.

[0046] The first water pan 4 can collect condensed water from the first evaporator 2 and part of the condensed water from the second evaporator 3, and the second water pan 5 can collect condensed water from the second evaporator 3, so that the air conditioner has a lower probability of water leakage and a better user experience.

[0047] Specifically, a front edge of the first water pan 4 is connected to a rear side of the bottom support base 112, and a rear edge of the second water pan 5 is connected to a front edge of the top surface of the bottom support base 112. Thus, it is ensured that the condensed water on the second evaporator 3 can flow smoothly into the first water pan 4 and the second water pan 5 under the action of gravity.

[0048] In some embodiments, as shown in Figure 1 The side of the bottom support base 112 facing the first air inlet 13 includes a first concave arc surface 1121 extending downward from the top surface of the bottom support base 112 to an outer surface of the first water pan 4 and a second concave arc surface 1122 extending upward from a lower edge of the first air inlet 13 to the outer surface of the first water pan 4, and the side of the bottom support base 112 facing the second air inlet 14 includes a third concave arc surface 1123 extending upward from a lower edge of the second air inlet 14 to an outer surface of the second water pan 5, wherein an angle of the first concave arc surface 1121 is P2, an angle of the second concave arc surface 1122 is P3, and an angle of the third concave arc surface 1123 is P4, and 22°≤P2≤45°, 25°≤P3≤60°, and / or 45°≤P4≤75°.

[0049] This arrangement makes the side of the air duct formed in the shell 1 and communicating with the first air inlet 13 and the second air inlet 14 to be streamline-shaped, and the concave arc surfaces make the air duct have a better guiding effect on the incoming air flow, a smaller wind loss, and a higher smoothness of the incoming air flow passing through the first evaporator 2 and the second evaporator 3.

[0050] Specifically, the angles of the above-mentioned concave arc surfaces refer to the central angles of projections of the concave arc surfaces on a projection plane perpendicular to the length direction of the shell 1, P2 can be 22°, 30°, and 45°, P3 can be 25°, 45°, and 60°, and P4 can be 45°, 60°, and 75°.
