[0034] Hereinafter, a fresh air module 10 of an air conditioner according to an embodiment of the present utility model will be described with reference to the accompanying drawings.

[0035] like Figure 1-Figure 8 As shown, the fresh air module 10 of the air conditioner according to the embodiment of the utility model comprises: a fresh air fan 11 and an air outlet structure 12, the top of the fresh air fan 11 is the fan outlet; the air outlet structure 12 is arranged at the top of the fresh air fan 11, and comprises a rear air outlet section 123 extending backward and upward along the air outlet direction, and a front air outlet section 124 extending forward and upward along the air outlet direction, the inlet 1231 of the rear air outlet section 123 is connected to the fresh air fan 11 and communicated with the fan outlet, the inlet 1241 of the front air outlet section 124 is connected to the front wall 123a of the rear air outlet section 123 and communicated with the rear air outlet section 123, and the inlet width W1 of the front air outlet section 124 in the left-right direction is smaller than the air duct width W2 of the rear air outlet section 123 at the place where the rear air outlet section 123 is connected with the front air outlet section 124. Thus, small flow diversion can be achieved, which is conducive to reducing noise.

[0036] First, if Figure 1-Figure 3 As shown, the air conditioner 100 is provided with a fresh air module 10, the fresh air module 10 includes a fresh air fan 11 and an air outlet structure 12, a fresh air inlet 111 is provided on the rear side of the fresh air fan 11, the fresh air inlet 111 is connected with the outdoor space through a fresh air duct, and a fan outlet is provided on the top of the fresh air fan 11. When the fresh air fan 11 is running, the fresh air fan 11 can inhale the fresh air flow from the fresh air inlet 111 and blow it upwards from the fan outlet.

[0037] The air outlet structure 12 is arranged at the top of the fresh air fan 11, and the air outlet structure 12 includes a rear air outlet section 123 and a front air outlet section 124. The rear air outlet section 123 is extended to the rear and upward along the air outlet direction. The upper end of the rear air outlet section 123 is provided with an outlet 1232 open to the rear and the lower end is provided with an inlet 1231. The inlet 1231 of the rear air outlet section 123 is connected to the fresh air fan 11 and communicated with the fan outlet. The front air outlet section 124 is extended to the front and upward along the air outlet direction. The upper end of the front air outlet section 124 is provided with an outlet 1242 open to the front and the lower end is provided with an inlet 1241. The inlet 1241 of the front air outlet section 124 is connected to the front wall 123a of the rear air outlet section 123 and communicated with the rear air outlet section 123.

[0038] Specifically, when the fresh air fan 11 is running, the fresh air fan 11 can inhale the fresh air flow through the fresh air inlet 111, and the fresh air flow can be blown into the rear air outlet section 123 through the fan outlet, and the fresh air flow flows along the rear air outlet section 123 and is divided into two parts, the first part continues to flow along the rear air outlet section 123 to be blown to the rear side of the fresh air module 10 from the outlet 1232 of the rear air outlet section 123, and the second part can flow into the front air outlet section 124 to flow along the front air outlet section 124, and be blown out from the outlet 1242 of the front air outlet section 124 to the front side of the fresh air module 10. In this way, the air outlet range of the fresh air flow can be increased.

[0039] Among them, Figure 4 As shown, the distance between the left side wall 123b and the right side wall 123c of the rear air outlet section 123 constitutes the air duct width of the rear air outlet section 123, the inlet width of the front air outlet section 124 in the left and right directions is W1, and the distance W2 between the left side wall 123b and the right side wall 123c at the height of the inlet 1241 of the front air outlet section 124 satisfies: W1<W2. Thus, the fresh air flow (the first part of the fresh air flow) that continues to flow along the rear air outlet section 123 and flows out from the outlet 1232 of the rear air outlet section 123 can be greater than the fresh air flow (the second part of the fresh air flow) diverted to the front air outlet section 124, and small flow diversion can be achieved with less noise.

[0040] According to the fresh air module 10 of the air conditioner in the embodiment of the utility model, by setting the inlet width of the front air outlet section 124 in the left and right directions to be smaller than the air duct width of the rear air outlet section 123 at the connection point with the front air outlet section 124, the fresh air flow diverted from the rear air outlet section 123 to the front air outlet section 124 can be made relatively small, thereby realizing small flow diversion, which is beneficial to reducing noise and improving user comfort.

[0041] In some embodiments of the present invention, Figure 4As shown, the inlet 1241 of the front air outlet section 124 can be arranged to be offset to one side of the center line z of the front wall 123a of the rear air outlet section 123 in the left-right direction; wherein the center line z is parallel to the extension direction of the rear air outlet section 123 from the inlet 1231 to the outlet 1232 and is located in the middle of the rear air outlet section 123 in the left-right direction. Exemplarily, the inlet 1241 of the front air outlet section 124 can be arranged to the left of the center line z of the front wall 123a of the rear air outlet section 123. Through the above arrangement, the space occupied by the front air outlet section 124 can be reduced, which is conducive to the miniaturization design of the fresh air module 10.

[0042] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the width of the air duct of the front air outlet section 124 in the left and right direction can be set to gradually increase from the inlet 1241 to the outlet 1242. Through the above arrangement, the air outlet area of ​​the front air outlet section 124 can be increased, which is conducive to increasing the air outlet range of the fresh air flow and improving user satisfaction.

[0043] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the inlet 1241 of the front air outlet section 124 can be set to be offset to one side of the center line z of the front wall 123a of the rear air outlet section 123 in the left-right direction, wherein the center line z is parallel to the extension direction of the rear air outlet section 123 from the inlet to the outlet and is located in the middle of the rear air outlet section 123 in the left-right direction. At the same time, the wall surface of one side of the left and right side walls of the front air outlet section 124 close to the center line z of the front wall 123a can be straight, and the wall surface of the other side can be inclined from the inlet 1241 to the outlet 1242 toward the direction away from the center line z of the front wall 123a, and the size of the front air outlet section 124 in the left-right direction can be gradually increased in the direction from the inlet 1241 to the outlet 1242.

[0044] Through the above arrangement, the front air outlet section 124 can have a larger air outlet range in the left and right directions, and the size of the inlet 1241 can be smaller, thereby reducing the occupancy of the front wall 123a of the rear air outlet section 123 by the front air outlet section 124, which is beneficial to reducing the overall size of the fresh air module 10.

[0045] In some embodiments of the present invention, Figure 3 and Figure 4As shown, the direction of the front air outlet section 124 from the inlet 1241 to the outlet 1242 is the extension direction L2 of the front air outlet section 124, and the spacing H between the upper wall 124a and the lower wall 124b of the front air outlet section 124 in the direction perpendicular to the extension direction L2 of the front air outlet section 124 gradually decreases from the inlet 1241 to the outlet 1242. Through the above arrangement, in the process of the fresh air flow flowing from the inlet 1241 along the front air outlet section 124 to the outlet 1242, the flow rate of the fresh air flow can be gradually increased, so that the flow rate of the fresh air flow blown out of the front air outlet section 124 is relatively large, so that the fresh air flow can be blown to a farther position, which is conducive to improving user satisfaction.

[0046] In some embodiments of the present invention, Figure 3-Figure 5 As shown, the center line L1 of the rear air outlet section 123 extending from the inlet to the outlet can be set to be an arc shape. Of course, the center line L1 of the rear air outlet section 123 extending from the inlet to the outlet can also be set to be an elliptical arc shape or a curve shape, and this application does not limit this. Through the above setting, the wind resistance of the fresh air flow when flowing along the rear air outlet section 123 can be reduced, the flow rate of the fresh air flow can be increased, and the air volume can be increased.

[0047] In some embodiments of the present invention, Figure 5 As shown, the air outlet structure 12 includes a left shell 121 and a right shell 122 which are formed separately. The left shell 121 and the right shell 122 are arranged in the left-right direction and spliced ​​together. The air outlet structure 12 consists of the left shell 121 and the right shell 122. The left shell 121 and the right shell 122 jointly define a front air outlet section 124 and jointly define a rear air outlet section 123.

[0048] Through the above arrangement, the structure of the air outlet structure 12 can be simplified, so that the air outlet structure 12 is easy to manufacture and assemble, which is beneficial to reducing the processing cost of the fresh air module 10.

[0049] In some embodiments of the present invention, Figure 5 As shown, a left clamping portion 1211 may be provided on the left shell 121, and a right clamping portion 1221 may be provided on the right shell 122, and the left clamping portion 1211 and the right clamping portion 1221 may be clamped and matched to connect the left shell 121 and the right shell 122 as a whole. For example, the left clamping portion 1211 may be set as a bayonet, and the right clamping portion 1221 may be set as a buckle; or, the right clamping portion 1221 may be set as a bayonet, and the left clamping portion 1211 may be set as a buckle, and the present application does not limit this. Thus, the difficulty of assembling the left shell 121 and the right shell 122 may be reduced, and the practicality of the air outlet structure 12 may be improved.

[0050] In some embodiments of the present invention, Figure 5As shown, the left clamping part 1211 and the right clamping part 1221 can be provided in multiple numbers, and the multiple left clamping parts 1211 and the multiple right clamping parts 1221 correspond to each other one by one to form multiple clamping structures. The multiple clamping structures are divided into three groups, and the three groups of clamping structures are respectively arranged corresponding to the inlet 1231 of the rear air outlet section 123, the outlet 1232 of the rear air outlet section 123, and the outlet 1242 of the front air outlet section 124. Each group of clamping structures includes multiple clamping structures arranged along the front and rear directions of the air outlet structure 12, and the multiple clamping structures of the same group are used to fix the air outlet structure 12 from the front and rear sides. In this way, the connection stability between the left shell 121 and the right shell 122 can be improved, and the reliability of the air outlet structure 12 can be improved.
