DETAILED DESCRIPTION

[0021] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings. The embodiments described below with 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.

[0022] The air conditioner according to the embodiments of the present application is described below in combination with Figure 1 and Figure 2

[0023] ​The air conditioner of the embodiment of the utility model includes shell 1, first rotating door 2, cross flow fan 4 and evaporator 5. Shell 1 is equipped with first air inlet 13, second air inlet 14, first air outlet 15 and second air outlet 16, the inner chamber of shell 1 includes collecting cavity 17, air outlet air duct 18, first air inlet air duct 19 and second air inlet air duct 110, first air outlet 15 and second air outlet 16 all communicate with collecting cavity 17 through air outlet air duct 18, first air inlet air duct 19 communicates collecting cavity 17 and first air inlet 13, second air inlet air duct 110 communicates collecting cavity 17 and second air inlet 14. First rotating door 2 is pivotably connected with shell 1, first rotating door 2 has first position of closing first air inlet 13 and second position of opening first air inlet 13. Cross flow fan 4 is installed in collecting cavity 17. Evaporator 5 is installed in second air inlet air duct 110, and evaporator 5 is located between cross flow fan 4 and second air inlet 14.

[0024] According to the air conditioner of the embodiment of the utility model, by setting that first rotating door 2 is pivotably connected with shell 1 between first position and second position, when the air conditioner works in the cooling mode or the heating mode, first rotating door 2 closes first air inlet 13, so that the air inlet flow can only enter second air inlet 14 into second air inlet air duct 110, and then is discharged to the indoor through first air outlet 15 and second air outlet 16 after heat exchange with evaporator 5. When the air conditioner works in the air supply mode, first rotating door 2 opens first air inlet 13, and the air inlet flow can mainly enter first air inlet 13 into first air inlet air duct 19, and then pass through collecting cavity 17 and air outlet air duct 18 and be discharged to the indoor through first air outlet 15 and second air outlet 16, that is, all air inlet flows do not need to pass through evaporator 5, thereby effectively reducing the air resistance of the air inlet flow, the working power of cross flow fan 4 is lower, and the energy consumption is smaller.

[0025] Need to be explained, the air conditioner further includes a driving device, the driving device is installed on the shell 1 and is transmission connected with the first rotating door 2, under the control of the driving device, the automatic switching of the first rotating door 2 between the first position and the second position can be realized. Wherein, the driving device can be a motor.

[0026] In some embodiments, as shown in Figure 1 and Figure 2 , first air inlet 13 is arranged on the lower side of shell 1, second air inlet 14 is arranged on the front side of shell 1, first air outlet 15 is arranged on the upper side of shell 1, and second air outlet 16 is arranged on the front side of shell 1 and above second air inlet 14.

[0027] That is, the air conditioner takes in air from the bottom and discharges air from the top, thereby effectively solving the problem of rapid sinking of the air outlet flow, and effectively improving the air outlet distance of the air conditioner and the indoor air circulation efficiency.

[0028] In some embodiments, the first rotating door 2 is located in the first air inlet duct 19, and the first rotating door 2 in the first position is located at one end of the first air inlet duct 19 away from the first air inlet 13.

[0029] Thus, the first rotating door 2 is effectively prevented from being exposed to affect the appearance of the air conditioner, and at the same time, in the cooling and heating modes, the air flow from the second air inlet duct 110 is prevented from entering and staying in the first air inlet duct 19 to cause wind loss, further ensuring the cooling and heating efficiency of the air conditioner.

[0030] In some embodiments, as shown in Figure 1 and Figure 2 , the width of the first rotating door 2 is L1, the width of the first air inlet 13 is L2, and the width of the second air inlet 14 is L3, wherein 80mm≤L1≤100mm, 120mm≤L2≤140mm, and 150mm≤L3≤170mm.

[0031] That is, the first rotating door 2 blocks the narrowest position of the first air inlet duct 19 to achieve the closing of the first air inlet 13, effectively reducing the opening and closing cost of the first air inlet 13. At the same time, by setting 120mm≤L2≤140mm, 150mm≤L3≤170mm, the air conditioner is ensured to have a larger air inlet area to have a larger air inlet amount, and the air outlet effect of the air conditioner is better, and the indoor air circulation efficiency is higher.

[0032] Specifically, L1 can be 80mm, 90mm and 100mm, L2 can be 120mm, 130mm and 140mm, and L3 can be 150mm, 160mm and 170mm.

[0033] In some embodiments, the air conditioner further comprises a second rotating door 3, the second rotating door 3 is pivotally connected with the shell 1, and the second rotating door 3 has a third position closing the first air outlet 15 and a fourth position closing the second air outlet 16.

[0034] Thus, in the air supply mode, the second rotating door 3 can be controlled to close the first air outlet 15 to make the air conditioner front air outlet, thereby giving the user a better air supply effect. At the same time, in the cooling and heating mode, the second rotating door 3 can also be controlled to close the second air outlet 16 to make the air conditioner top air outlet, thereby effectively solving the problem of rapid sinking of the air outlet airflow, and at the same time, the air outlet speed is improved by reducing the air outlet area, further improving the air outlet distance, and the indoor air circulation efficiency is higher.

[0035] Specifically, the second rotary door 3 can be switched automatically between the third position and the fourth position by the motor, so as to automatically close the first air outlet 15 or the second air outlet 16 according to the mode switching, and the mode switching of the air conditioner is flexible.

[0036] In some embodiments, as shown in Figure 1 and Figure 2 The width of the second rotary door 3 is L4, the width of the first air outlet 15 is L5, and the width of the second air outlet 16 is L6, wherein 70mm≤L4≤85mm, L4=L5=L6.

[0037] Thus, the air conditioner has a larger air outlet area and a larger air volume in any mode, and the indoor air circulation efficiency is higher.

[0038] Specifically, when the second rotary door 3 is in the third position, the top surface of the second rotary door 3 is substantially flush with the top surface of the shell 1, that is, the second rotary door 3 is located at the first air outlet 15. The air conditioner can switch the second rotary door 3 to the third position when not working. This setting not only blocks the first air outlet 15, but also effectively prevents external dust from entering the air outlet duct 18 through the first air outlet 15, effectively ensuring the cleanliness of the air conditioner and reducing the cleaning frequency of the air conditioner.

[0039] In some embodiments, the air outlet duct 18 includes a diffuser section 181 in communication with the collecting cavity 17. The width of the diffuser section 181 gradually increases away from the collecting cavity 17. The inner surface of the diffuser section 181 includes a first side surface 182 and a second side surface 183 opposite along the width direction of the shell 1. The first side surface 182 and the second side surface 183 form an angle W1, wherein 28°≤W1≤35°.

[0040] Thus, on the basis of a certain length of the diffuser section 181, the width of the end of the diffuser section 181 is larger, and the air conditioner has a larger air volume, so that the indoor air circulation efficiency is higher.

[0041] Specifically, the first air outlet 15 and the second air outlet 16 are located on the side of the diffuser section 181 away from the collecting cavity 17. The air duct width of the air outlet duct 18 located on the side of the diffuser section 181 away from the collecting cavity 17 is greater than or equal to the maximum width of the diffuser section 181. The first air outlet 15 and the second air outlet 16 are in communication with the air duct. The first side surface 182 and the second side surface 183 extend forwardly and obliquely towards the first air outlet 15 and the second air outlet 16. W1 can be 28°, 30°, 32°, and 35°.

[0042] In some embodiments, the air conditioner further includes a water pan 6 installed on the shell 1, and the water pan 6 is located above the lower end of the evaporator 5.

[0043] At this time, the water tray 6 separates the first air inlet duct 19 and the second air inlet duct 110. When the airflow passes through the first air inlet duct 19 and the second air inlet duct 110, it will not be blocked by the water tray 6 and will not cause wind power loss, thus further reducing the energy consumption of the cross-flow fan 4.

[0044] In some embodiments, the minimum width of the water receiving tray 6 is D, and the maximum height of the water receiving tray 6 is H, wherein 45mm≤D≤55mm and 28mm≤H≤35mm.

[0045] This design ensures that the water receiving tray 6 forms a sufficiently wide water receiving groove to better guarantee the reliability of condensate collection.

[0046] Specifically, the width of the outer contour of the water receiving tray 6 gradually increases from bottom to top, with its minimum width being the width of the bottom surface of the water receiving tray 6. Here, D can be 45mm, 50mm, or 55mm. The height difference between the uppermost edge of the higher portion on either side of the water receiving trough in the width direction of the water receiving tray 6 and the bottom surface of the water receiving tray 6 is H, where H can be 28mm, 30mm, 32mm, or 35mm.

[0047] In some embodiments, the projected outer contour of the evaporator 5 is strip-shaped on the projection plane perpendicular to the length direction of the housing 1.

[0048] At this time, the resistance of the airflow passing through the evaporator 5 is smaller, the power of the cross-flow fan 4 is smaller, and the energy consumption is lower. At the same time, when the airflow passes through the evaporator 5, the airflow can flow more evenly over the surface of the evaporator 5, so as to ensure that all parts of the evaporator 5 can fully participate in heat exchange, effectively avoiding uneven local heat exchange and affecting the heat exchange efficiency of the evaporator 5, and the air conditioner has higher cooling and heating efficiency.

[0049] For example, the evaporator 5 may be perpendicular to the extension direction of the second air inlet duct 110.

[0050] In some embodiments, such as Figure 1 As shown, the housing 1 includes a connected base 11 and a front panel 12. On the projection plane perpendicular to the length direction of the housing 1, the extension direction of the projection of the front panel 12 is consistent with the extension direction of the projection of the evaporator 5. The extension direction of the projection of the front panel 12 forms an angle W2 with the height direction of the base 11, where 5°≤W2≤15°.

[0051] That is, the evaporator 5 is in the form of an inclined plate angled with respect to the horizontal direction, so that the evaporator 5 can guide and comb the airflow passing through the evaporator 5 when the airflow passes through the evaporator 5, so that the airflow can flow more evenly over the surface of the evaporator 5, further improving the cooling and heating efficiency of the air conditioner. In addition, the inclined evaporator 5 also facilitates the flow of condensed water along the inclined surface to the water pan 6, effectively preventing water accumulation inside the evaporator 5, 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 12 makes the outer contour shape of the air conditioner closer to the outer contour shape of the air conditioner in the related art, with a high degree of aesthetic appearance.

[0052] Specifically, the width of the outer contour of the air conditioner gradually decreases from top to bottom, and the angle W2 between the evaporator 5 and the front panel 12 and the vertical direction can be 5°, 10°, 12°, and 15°.
