[0040] Referring to Figures 1, 2, 3 and 4, an embodiment of the present application provides an air outlet structure 10, which is used for cooling air outlet of an air-conditioning range hood 100. The air outlet structure 10 includes a fan assembly 11 and an air duct assembly 12. The fan assembly 11 has a first air outlet (not shown in the figure), and the air duct assembly 12 has an air outlet duct 13 inside, and the opposite ends of the air outlet duct 13 are respectively formed as an air inlet 14 and a second air outlet 15. The air inlet 14 is connected to the first air outlet, and the second air outlet 15 is arranged on the air-conditioning range hood 100.

[0041] It should be noted that the air-conditioning range hood 100 refers to a range hood capable of realizing a cooling function, wherein the air-conditioning range hood 100 generally includes a cooling module and a range hood module, the range hood module having a suction port and a fume outlet, through which the fume in the kitchen is sucked into the range hood module and then discharged through the fume outlet. The cooling module includes an air outlet structure 10, through which the generated cold air is blown into the kitchen to adjust the kitchen temperature.

[0042] Furthermore, the air outlet structure 10 includes a fan assembly 11 and an air duct assembly 12. The fan assembly 11 may include an evaporator, which can generate cold air. The cold air enters the air outlet duct 13 from the first air outlet on the evaporator through the air inlet 14, and then is blown out to the kitchen from the second air outlet 15.

[0043] During this process, since the second air outlet 15 is integrated into the air-conditioning range hood 100, there is no need to add additional air outlets on the kitchen ceiling, which improves the integrity of the air-conditioning range hood 100, simplifies the installation process of the air-conditioning range hood 100, and facilitates operation.

[0044] Specifically, the air inlet end of the air duct assembly 12 can be connected to the first air outlet of the evaporator, the air duct assembly 12 extends inside the air-conditioning range hood 100, and the air outlet end extends to the wall of the air-conditioning range hood 100, and an opening is opened on the wall of the air-conditioning range hood 100, so that the second air outlet 15 can be connected to the opening, thereby integrating the second air outlet 15 into the air-conditioning range hood 100.

[0045] Through the above structure, the fan assembly 11 can generate airflow and send the airflow out through the duct assembly 12. Specifically, the air inlet 14 of the air outlet duct 13 is connected to the first air outlet of the fan assembly 11. The airflow enters the air inlet 14 from the first air outlet to enter the air outlet duct 13, and then is blown out through the second air outlet 15. Among them, since the second air outlet 15 is integrated in the air-conditioning range hood 100, there is no need to add an additional air outlet on the kitchen ceiling, which improves the integrity of the air-conditioning range hood 100, simplifies the installation process of the air-conditioning range hood 100, and facilitates operation.

[0046] In some embodiments, in a plane intersecting with the extension direction X of the air outlet duct 13 , a projected area of ​​the second air outlet 15 is greater than a projected area of ​​the air inlet 14 .

[0047] Specifically, the air outlet duct 13 is extended in the horizontal direction inside the air conditioning range hood 100 , and in a vertical plane perpendicular to the extension direction X of the air outlet duct 13 , the projection area of ​​the second air outlet 15 is larger than the projection area of ​​the air inlet 14 .

[0048] Therefore, after the cold air generated by the evaporator enters the air outlet duct 13 through the air inlet 14, it can be blown out from the second air outlet 15 with a larger area, thereby expanding the air supply area and improving the cooling comfort.

[0049] In some embodiments, in the direction from the air inlet 14 to the second air outlet 15, the air outlet duct 13 includes a starting section 131, a transition section 132 and an outlet section 133 arranged in sequence. In which, along the extension direction X of the air outlet duct 13, the widths of the starting section 131, the transition section 132 and the outlet section 133 gradually decrease.

[0050] Specifically, along the flow direction of the cold air, the air outlet duct 13 can be sequentially divided into a starting section 131, a transition section 132 and an outlet section 133, and in the flow direction, the widths of the starting section 131, the transition section 132 and the outlet section 133 gradually decrease. That is, in the flow direction of the cold air, the width of the starting section 131 is the largest, followed by the transition section 132, and the width of the outlet section 133 is the smallest.

[0051] With the above structure, the width of the starting section 131 is the largest. After the cold air is discharged from the evaporator and enters the air outlet duct 13, the airflow can be turned, that is, from flowing from top to bottom to flowing horizontally. Therefore, the width of the starting section 131 can provide sufficient space for the airflow to turn, avoiding the airflow turning too quickly and causing an increase in wind resistance.

[0052] When the airflow passes through the starting section 131 and enters the transition section 132 , the transition section 132 can further diffuse the airflow so that the distribution is more uniform. Therefore, after the airflow passes through the transition section 132 , the airflow can be more uniformly distributed in the air outlet duct 13 .

[0053] Finally, the airflow is further diffused through the outlet section 133 , so that the airflow can be evenly distributed in the second air outlet 15 and blown out through the second air outlet 15 .

[0054] As a result, the cold air flow can be diffused through the starting section 131, the transition section 132 and the outlet section 133 in sequence, so that the air flow is more evenly distributed in the air outlet duct 13, thereby improving the cooling comfort.

[0055] As shown in FIG. 5 , in some embodiments, the width of the starting section 131 is N1 , the width of the transition section 132 is N2 , the width of the exit section 133 is N3 , and N1 : N2 : N3 = 7:2:1.

[0056] After simulation analysis of the air outlet uniformity of the second air outlet 15 , the widths of the starting section 131 , the transition section 132 and the outlet section 133 are set to the above ratio range, which can effectively improve the uniformity of the airflow at the second air outlet 15 and enhance the cooling comfort of the air outlet structure 10 .

[0057] In some embodiments, N1 ranges from 150 mm to 250 mm, and / or, N2 ranges from 30 mm to 100 mm, and / or, N3 ranges from 10 mm to 50 mm.

[0058] Preferably, N1 ranges from 180 mm to 220 mm, and / or N2 ranges from 45 mm to 80 mm, and / or N3 ranges from 20 mm to 40 mm.

[0059] Specifically, the length of the starting section 131 can be adjusted according to the size of the volute outlet of the evaporator, the length of the transition section 132 can be set to 400mm~790mm, the length of the outlet section 133 can be set to 600mm~900mm, and the height of the second air outlet 15 can be set to 60mm~100mm.

[0060] Therefore, the size of the air outlet structure 10 can meet the actual needs and improve the air outlet uniformity and cooling comfort as much as possible.

[0061] In some embodiments, the position where the transition section 132 connects with the outlet section 133 has a first arc 16 and a second arc 17 , the first arc 16 is connected between the outlet section 133 and the second arc 17 , and the arc radius of the first arc 16 is smaller than the arc radius of the second arc 17 .

[0062] Specifically, when the airflow flows from the transition section 132 into the outlet section 133 , the airflow can flow into the outlet section 133 more smoothly under the guidance of the second arc 17 and the first arc 16 in turn, and diffuse evenly in the process, so as to be more evenly distributed in the outlet section 133 .

[0063] Furthermore, the airflow first passes through the second arc 17, and flows toward the first arc 16 under the guidance of the second arc 17, and finally enters the outlet section 133 under the guidance of the first arc 16. Therefore, setting the arc radius of the first arc 16 to be smaller than the arc radius of the second arc 17 enables the airflow to enter the outlet section 133 more smoothly and evenly.

[0064] In some embodiments, the arc radius of the first arc 16 is 5 mm to 20 mm, and / or the arc radius of the second arc 17 is 40 mm to 60 mm.

[0065] Setting the arc radii of the first arc 16 and the second arc 17 within the above range can improve the smoothness of the airflow between the transition section 132 and the outlet section 133 , so that the airflow can enter the outlet section 133 more smoothly and evenly from the transition section 132 .

[0066] In addition, the arc radii of the first arc 16 and the second arc 17 can be adjusted according to actual usage, which will not be elaborated here.

[0067] In some embodiments, the length of the outlet section 133 is L1, the length of the transition section 132 is L2, the length of the starting section 131 is L3, and L1>L2>L3.

[0068] Thus, the air flow enters the air outlet duct 13 from the evaporator, and thus passes through the starting section 131, the transition section 132 and the outlet section 133. During the flow, the air flow can gradually diffuse and evenly fill the starting section 131, the transition section 132 and the outlet section 133, and finally blown out from the outlet section 133.

[0069] Through the above structure, the airflow can smoothly and evenly pass through the starting section 131, the transition section 132 and the outlet section 133, and finally blow out from the outlet section 133. At the same time, the area of ​​the second air outlet 15 can be increased, so that the cooling area of ​​the air outlet structure 10 is larger, and the cooling effect is improved.

[0070] In some embodiments, the air outlet structure 10 further includes an air guide component 18 disposed inside the air outlet duct 13 , and the air guide component 18 is used to guide the airflow inside the air outlet duct 13 from the air inlet 14 to the second air outlet 15 .

[0071] When the airflow passes through the starting section 131 , the transition section 132 and the outlet section 133 in sequence, the air guide assembly 18 can play a good guiding role, so that the airflow can pass through the starting section 131 , the transition section 132 and the outlet section 133 more smoothly and evenly, and finally blow out from the outlet section 133 .

[0072] In some embodiments, the air guide assembly 18 includes a first air guide plate 181 and a second air guide plate 182, one end of the first air guide plate 181 and the second air guide plate 182 are both located at the starting section 131, and the other end is both located at the transition section 132. The first air guide plate 181 and the second air guide plate 182 are spaced apart in the width direction of the starting section 131.

[0073] Specifically, the first air guide plate 181 and the second air guide plate 182 are used to guide the airflow between the starting section 131 and the transition section 132 , that is, to smoothly guide the airflow in the starting section 131 to the transition section 132 and make the airflow evenly distributed in the transition section 132 .

[0074] In addition, the first air guide plate 181 and the second air guide plate 182 are spaced apart in the width direction of the starting section 131 , so that the contact area between the airflow and the first air guide plate 181 and the second air guide plate 182 is larger, thereby improving the guiding effect of the airflow.

[0075] In some embodiments, the first air guide plate 181 and the second air guide plate 182 are bent and extended along the extension direction X of the air outlet duct 13, and divide the starting section 131 into three air sections, wherein the widths of the air inlet ends of the three air sections are a1, b1, and c1, respectively, and the widths of the air outlet ends of the three air sections are a2, b2, and c2, respectively, and a1:b1:c1=a2:b2:c2.

[0076] As a result, the airflow can be more evenly distributed in the three air sections, and thus flow into the transition section 132 more evenly.

[0077] In addition, the widths of the air inlet ends of the three air sections are set to a1, b1, and c1, respectively, and the widths of the air outlet ends of the three air sections are set to a2, b2, and c2, respectively, and a1:b1:c1= a2:b2:c2. When the first air guide plate 181 and the second air guide plate 182 are used together to guide the airflow, the airflow can be distributed more evenly in the three air sections, thereby improving the guiding effect.

[0078] In some embodiments, along the extension direction X of the air outlet duct 13, the first ends of the first air guide plate 181 and the second air guide plate 182 are away from the transition section 132 and are perpendicular to the outlet plane of the starting section 131. The second ends of the first air guide plate 181 and the second air guide plate 182 are close to the transition section 132, and the angle between the second end of the first air guide plate 181 and the outlet plane of the transition section 132 is α1, and the angle between the second end of the second air guide plate 182 and the outlet plane of the transition section 132 is α2, wherein α1>α2, and 8°≤α1≤15°.

[0079] When the airflow flows in the starting section 131 and the transition section 132 , the airflow first reaches the first ends of the first air guide plate 181 and the second air guide plate 182 , and then reaches the second ends of the first air guide plate 181 and the second air guide plate 182 .

[0080] The first ends of the first air guide plate 181 and the second air guide plate 182 are both perpendicular to the outlet plane of the starting section 131 , so that the airflow in the outlet section 133 can enter the transition section 132 smoothly and evenly.

[0081] The angle between the second end of the first air guide plate 181 and the outlet plane of the transition section 132 is α1, and the angle between the second end of the second air guide plate 182 and the outlet plane of the transition section 132 is α2, wherein α1>α2, and 8°≤α1≤15°. Thus, under the guidance of the first air guide plate 181 and the second air guide plate 182, the airflow can be distributed in the transition section 132 stably and evenly.

[0082] In some embodiments, the air guide assembly 18 further includes a third air guide plate 183 disposed in the transition section 132 . The third air guide plate 183 is constructed as an arc structure, and the concave surface is disposed toward the first air guide plate 181 and the second air guide plate 182 .

[0083] Specifically, the third air guide plate 183 is set to a 90° single arc structure, that is, one end of the third air guide plate 183 is tangentially connected to the rear wall surface of the transition section 132, and the other end is perpendicular to the outlet plane of the transition section 132 and located in the middle of the outlet plane of the transition section 132.

[0084] Thus, the third air guide plate 183 can guide the airflow in the transition section 132 to make it flow smoothly and evenly into the outlet section 133 .

[0085] In some embodiments, an air guide port 184 is formed through the third air guide plate 183 , and the total area of ​​the air guide port 184 is set to be 40%-60% of the area of ​​the third air guide plate 183 .

[0086] By setting the air guide port 184 , the third air guide plate 183 can guide the airflow so that the airflow passes through the third air guide plate 183 and evenly fills the left side of the third air guide plate 183 , so that the airflow can be more evenly distributed to the outlet section 133 .

[0087] Furthermore, the air guide port 184 can be provided as one or multiple air guide ports 184 can be provided at intervals, and the shape of the air guide port 184 can be, but is not limited to, a long strip, a circle, a square, etc.

[0088] In addition, in order to verify the actual effect of uniform air discharge of the present application after the first air guide plate 181, the second air guide plate 182 and the third air guide plate 183 are provided, a simulation analysis is performed on the air discharge uniformity of the second air outlet 15. As shown in FIG6, when the air guide plate structure is not provided inside the air outlet duct 13, the air flow is mainly concentrated on the right side of the second air outlet 15, so that the cold air discharge is relatively concentrated and the cooling effect is poor.

[0089] As shown in FIG. 7 , when the first air guide plate 181 , the second air guide plate 182 and the third air guide plate 183 are provided, the distribution and speed of the cold air flow at the second air outlet 15 are more uniform, which can effectively improve the cooling comfort.

[0090] Based on the same concept as the above-mentioned air outlet structure 10 , the present application also provides an air-conditioning range hood 100 , including a range hood module 20 and an air-conditioning module connected to each other, the air-conditioning module including the above-mentioned air outlet structure 10 , and a second air outlet 15 is opened on the range hood module 20 .

[0091] The hood module 20 is provided with a smoke inlet 21 and a fume outlet 22. The fume in the kitchen is sucked into the hood module 20 through the smoke inlet 21 and then discharged through the fume outlet 22. At the same time, the air outlet structure 10 is arranged inside the hood module 20, and the second air outlet 15 is integrated on the hood module 20.

[0092] Furthermore, the inlet 21 is arranged at the bottom to facilitate the extraction of oil smoke. The oil smoke outlet 22 is arranged at the top to discharge the oil smoke. The second air outlet 15 is arranged between the inlet 21 and the oil smoke outlet 22, and the length of the second air outlet 15 is arranged to match the width of the range hood module 20, so as to maximize the air outlet area and air outlet range and improve the cooling effect.

[0093] According to one or more embodiments, during use, the air conditioning range hood 100 can suck the fumes in the kitchen through the smoke inlet 21 and discharge the fumes through the fumes outlet 22. At the same time, the cold air generated by the evaporator first enters the starting section 131 of the air outlet duct 13 through the first air outlet and the air inlet 14. Under the guidance of the first air guide plate 181 and the second air guide plate 182, the cold air gradually diffuses and flows into the transition section 132, and is evenly distributed in the transition section 132.

[0094] Furthermore, under the joint guidance of the first air guide plate 181, the second air guide plate 182 and the third air guide plate 183, the air flow in the transition section 132 smoothly and evenly enters the outlet section 133, and then is blown out from the outlet section 133 through the second air outlet 15, thereby achieving the cooling effect of the air-conditioning range hood 100.

[0095] Therefore, when the air-conditioning range hood 100 of the present application is in use, the fan assembly 11 can generate airflow and send the airflow out through the duct assembly 12. Specifically, the air inlet 14 of the air outlet duct 13 is connected to the first air outlet of the fan assembly 11, and the airflow enters the air inlet 14 from the first air outlet to enter the air outlet duct 13, and then is blown out through the second air outlet 15. Since the second air outlet 15 is integrated on the air-conditioning range hood 100, there is no need to add an additional air outlet on the indoor ceiling, which improves the integrity of the air-conditioning range hood 100, simplifies the installation process of the air-conditioning range hood 100, and facilitates operation.

[0096] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0097] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
