Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning range hoods, in particular to an air outlet system and an air-conditioning range hood. Background Art

[0002] The kitchen is the main place for people to cook, and the quality of the kitchen space environment directly affects people's cooking experience. In the related art, there appears an air-conditioning range hood, which can blow cold air when the user is cooking, improving the user's cooking experience. Due to the existence of the smoke exhaust pipe of the range hood in the air-conditioning range hood, the cold air outlet system on the evaporation side is located on one side of the top plate, and the air outlet direction is severely inclined to one side, resulting in the deflector for up and down air guiding being unable to effectively guide air towards the human body. Content of the Utility Model

[0003] In view of this, the utility model provides an air outlet system and an air-conditioning range hood to solve the problem that the air-conditioning range hood in the related art cannot effectively guide air towards the human body.

[0004] In the first aspect, the utility model provides an air outlet system, including:

[0005] A body having an air inlet and an air outlet, the air inlet being adapted to communicate with the volute outlet of the evaporator assembly, and the air outlet extending in a direction parallel to the length direction of the range hood;

[0006] A first air guiding structure for partitioning the interior of the body into a plurality of chambers, each of the chambers communicating with the air inlet and the air outlet;

[0007] A second air guiding structure provided at the air outlet for guiding the air flow blown out from each chamber towards the front side;

[0008] A third air guiding structure provided at the air outlet for sweeping air up and down.

[0009] Beneficial effects: The first air guiding structure partitions the interior of the body into a plurality of chambers, thereby realizing the distribution of the air volume in the lateral area. The second air guiding structure guides the air flow blown out from each chamber towards the front side, avoiding the air blowing obliquely to one side, ensuring that the third air guiding structure can effectively guide air. The third air guiding structure sweeps air up and down, enabling a relatively large air supply range in the longitudinal direction and meeting the air supply requirements within the height range of conventional users. Therefore, no matter where the user is in the cooking area, they can be blown by the air, meeting the user's requirement for air feeling comfort.

[0010] In an optional embodiment, the second air guiding structure includes an orifice plate provided with a plurality of air guiding holes.

[0011] Beneficial effects: The second flow guiding structure includes an orifice plate which is provided with a plurality of flow guiding holes. The structure of the second flow guiding structure is simple, and it can effectively guide the air flow blown out from each chamber forward, changing the direction of the air flow blown out from each chamber.

[0012] In an optional embodiment, the orifice plate is arranged at the rear side of the third flow guiding structure, and the flow guiding holes are inclined upward from back to front.

[0013] Beneficial effects: The orifice plate is arranged at the rear side of the third flow guiding structure. The air flow blown out from each chamber is first guided forward through the flow guiding holes on the orifice plate. From back to front, the flow guiding holes are inclined upward, which can effectively ensure that the air flow blown out through the flow guiding holes can blow onto the third flow guiding structure, thereby ensuring that the third flow guiding structure can effectively control the longitudinal range of the blown air flow and meet the air supply requirements within the height range of regular users.

[0014] In an optional embodiment, the aperture of the flow guiding hole is d1, and 2 mm ≤ d1 ≤ 15 mm;

[0015] and / or, the inclination angle of the flow guiding hole is a1, and 3° ≤ a1 ≤ 15°;

[0016] and / or, the hole pitch between two adjacent flow guiding holes is d2, and 1 mm ≤ d2 ≤ 2 mm;

[0017] and / or, the thickness of the orifice plate is d3, and 5 mm ≤ d3 ≤ 7 mm.

[0018] Beneficial effects: By setting the parameters of the aperture of the flow guiding hole, and / or the inclination angle of the flow guiding hole, and / or the hole pitch between the flow guiding holes, and / or the thickness of the orifice plate, more air flow can be blown onto the third flow guiding structure, thereby ensuring that the third flow guiding structure can effectively control the longitudinal range of the blown air flow and meet the air supply requirements within the height range of regular users.

[0019] In an optional embodiment, the third flow guiding structure includes at least one outer flow guiding plate which is arc-shaped, and the outer flow guiding plate is swingably arranged at the air outlet.

[0020] Beneficial effects: The third flow guiding structure includes at least one outer flow guiding plate. The up-and-down swing of the outer flow guiding plate can achieve up-and-down air sweeping and control the longitudinal range of the blown air flow. Since the outer flow guiding plate is arc-shaped, the air flow can be blown out more smoothly.

[0021] In an optional embodiment, there are two outer flow guiding plates which are arranged at intervals in the up-and-down direction.

[0022] Beneficial effects: By arranging two outer flow guiding plates and arranging them at intervals in the up-and-down direction, it can further ensure the effective control of the longitudinal range of the blown air flow and meet the air supply requirements within the height range of regular users.

[0023] In an alternative embodiment, the third air guiding structure has a wind blowing-in mode in which the wind sweeps within a first angular range and a wind avoiding people mode in which the wind sweeps within a second angular range.

[0024] Beneficial effects: By enabling the third air guiding structure to have a wind blowing-in mode and a wind avoiding people mode, it can be selected according to user needs, improving the user experience.

[0025] In an alternative embodiment, the first angular range means that the included angle between the outer air guiding plate and the vertical plane is 50° - 90°, and the second angular range means that the included angle between the outer air guiding plate and the vertical plane is 0° - 50°.

[0026] Beneficial effects: When the outer air guiding plate swings between 0° and 50°, the airflow guided by the outer air guiding plate can be prevented from blowing towards the user. When the outer air guiding plate swings between 50° and 90°, the airflow guided by the outer air guiding plate longitudinally covers 1m - 1.9m, meeting the air supply requirements within the conventional user height range.

[0027] In an alternative embodiment, the central angle corresponding to the outer air guiding plate is θ1, and 5° ≤ θ1 ≤ 20°.

[0028] Beneficial effects: Since the central angle corresponding to the outer air guiding plate is between 5° and 20°, it is convenient for the flexible swing of the outer air guiding plate and does not occupy a large space at the air outlet.

[0029] In an alternative embodiment, the main body includes a main body part and an air outlet frame. The air outlet frame is communicated with the outlet of the main body part. The first air guiding structure is arranged inside the main body part, the second air guiding structure is arranged at the outlet of the main body part, the third air guiding structure is arranged inside the air outlet frame, and the outlet of the air outlet frame constitutes the air outlet.

[0030] Beneficial effects: Since the third air guiding structure is arranged inside the air outlet frame, both sides of the air guiding structure can be fully exposed to the wind, which can prevent the third air guiding structure from generating condensation.

[0031] In an alternative embodiment, the distance between the bottom of the air outlet frame and the plane where the bottom of the outlet of the main body part is located is h1, and 5mm ≤ h1 ≤ 20mm.

[0032] Beneficial effects: By lowering the bottom of the air outlet frame by h1 relative to the bottom of the outlet of the main body part, it can ensure that the airflow blown out from the bottom of the main body part can also blow onto the outer air guiding plate, thereby ensuring that the third air guiding structure can effectively control the longitudinal range of the airflow blown out.

[0033] In an alternative embodiment, the distance between the top end of the air outlet frame and the horizontal plane where the top end of the outlet of the main body is located is h2, and h2 = h1.

[0034] Beneficial effects: By lowering the top end of the air outlet frame by h2 relative to the top end of the outlet of the main body, it can ensure that the air flow blown from the top of the main body can reach the outer deflector, so as to ensure that the third deflector structure can effectively control the longitudinal range of the air flow blown out.

[0035] In an alternative embodiment, the top of the air outlet frame is arc-shaped.

[0036] Beneficial effects: Since the top of the air outlet frame is arc-shaped, it can guide the air flow blown from the top of the main body, making the air flow more smooth, thereby reducing the wind resistance.

[0037] In an alternative embodiment, the angle between the tangent line at the connection of the top of the air outlet frame and the outlet of the main body and the horizontal plane is θ2, and 10° ≤ θ2 ≤ 50°.

[0038] Beneficial effects: By making the angle between the tangent line at the connection of the top of the air outlet frame and the outlet of the main body and the horizontal plane between 10° and 50°, on the one hand, it can guide the air flow blown from the top of the main body, making the air flow more smooth, and on the other hand, it will not interfere with the outer deflector, so that both sides of the outer deflector can be fully and evenly affected by the wind, avoiding condensation.

[0039] In an alternative embodiment, the orifice plate is arranged on the front side of the third deflector structure, and the inclination angles of the diversion holes are different from top to bottom.

[0040] Beneficial effects: Since the orifice plate is arranged on the front side of the third deflector structure and the third deflector structure cannot realize air supply in the up and down directions of the human body, the inclination angles of the diversion holes are different from top to bottom to realize air supply in the up and down ranges.

[0041] In an alternative embodiment, the main body is provided with an air inlet chamber facing the air inlet, an air outlet chamber communicated with the air inlet chamber, and in the direction parallel to the length direction of the range hood, the length of the air outlet chamber is greater than the length of the air inlet chamber, and the first deflector structure is arranged in the air outlet chamber.

[0042] Beneficial effects: The air inlet chamber is directly opposite to the air inlet. Therefore, the cold air blown out from the volute outlet of the evaporator assembly first enters the air inlet chamber, and then flows to the air outlet chamber and is blown out from the air outlet. Since the length of the air outlet chamber is greater than that of the air inlet chamber in the direction parallel to the length direction of the range hood, and the air outlet has a relatively large length, the air outlet range can be increased. By arranging the first flow guiding structure in the air outlet chamber, the air outlet uniformity at the air outlet can be improved, making the user feel more comfortable.

[0043] In an alternative embodiment, the first flow guiding structure includes a plurality of inner flow guiding plates, and each flow guiding plate is provided with an opening to communicate the respective chambers. The plurality of inner flow guiding plates make the distances from the outlets of the respective chambers equal or approximately equal.

[0044] Beneficial effects: The plurality of inner flow guiding plates make the distances from the outlets of the respective chambers equal or approximately equal, which can further improve the air outlet uniformity at the air outlet, making the user feel more comfortable.

[0045] In an alternative embodiment, the air outlet chamber has a first side wall and a second side wall arranged opposite to each other. The first side wall is close to the evaporator assembly, and the second side wall is far from the evaporator assembly. From the first side wall to the second side wall, the plurality of inner flow guiding plates are successively the first inner flow guiding plate, the second inner flow guiding plate, the third inner flow guiding plate, and the fourth inner flow guiding plate.

[0046] Beneficial effects: The first inner flow guiding plate, the second inner flow guiding plate, the third inner flow guiding plate, and the fourth inner flow guiding plate divide the air outlet chamber into five chambers, and all of these five chambers can blow air, thereby achieving air outlet uniformity in the transverse direction.

[0047] In an alternative embodiment, the starting end of the first inner flow guiding plate is arranged on the first side wall, and the included angle between the tangent line at the starting end of the first inner flow guiding plate and the first side wall is α1, where 0° ≤ α1 ≤ 45°;

[0048] and / or, the central angle corresponding to the first inner flow guiding plate is β1, where 45° ≤ β1 ≤ 90°;

[0049] and / or, the ratio of the opening area on the first inner flow guiding plate to the area of the first inner flow guiding plate is A1, where 20% ≤ A1 ≤ 30%;

[0050] and / or, the starting ends of the second inner flow guiding plate, the third inner flow guiding plate, and the fourth inner flow guiding plate are arranged on the rear wall of the body, and the starting ends of the second inner flow guiding plate, the third inner flow guiding plate, and the fourth inner flow guiding plate are tangent to the rear wall of the body;

[0051] and / or, the central angles corresponding to the second inner flow guiding plate, the third inner flow guiding plate, and the fourth inner flow guiding plate are all 90°;

[0052] And / or, the ratio of the opening area on the second inner deflector to the area of the second inner deflector is A2, and 65% ≤ A2 ≤ 85%;

[0053] And / or, the ratio of the opening area on the third inner deflector to the area of the third inner deflector is A3, and 50% ≤ A3 ≤ 70%;

[0054] And / or, the ratio of the opening area on the fourth inner deflector to the area of the fourth inner deflector is A4, and 35% ≤ A4 ≤ 55%.

[0055] Beneficial effects: By setting the opening areas of the respective inner deflectors, it is possible to ensure the uniformity of air outlet in the lateral direction. In addition, each inner deflector is arc-shaped, which can make the air flow more smoothly and reduce the resistance of the air flow passing through.

[0056] In a second aspect, the present utility model further provides an air-conditioning range hood, including:

[0057] An air-conditioning module, including an evaporator assembly;

[0058] The air outlet system, and the air inlet is communicated with the volute outlet of the evaporator assembly.

[0059] Beneficial effects: For this air-conditioning range hood, the first air guiding structure can distribute the air volume in the lateral area, the second air guiding structure guides the air flow blown out from each chamber forward, avoiding the air blowing obliquely to one side, and the third air guiding structure sweeps the air up and down, so that a relatively large air supply range can be achieved longitudinally, meeting the air supply requirements within the height range of conventional users. Therefore, no matter where the user is in the cooking area, they can be blown by the wind, meeting the requirements of the user's wind feeling comfort. Description of the Drawings

[0076] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0077] The kitchen is the main place where people cook, and the quality of the kitchen space environment directly affects people's cooking experience. In related technologies, there has emerged an air-conditioning range hood that can blow cold air when users are cooking, improving the cooking experience of users. Due to the existence of the exhaust pipe of the range hood in the air-conditioning range hood, the cold air outlet system on the evaporation side is located on one side of the top plate, and the air outlet direction is severely inclined to one side, resulting in the deflector for up and down air guiding being unable to effectively guide air towards the human body.

[0078] Limited by the body space of the air-conditioning range hood, the air-conditioning range hoods in related technologies cannot meet the cold air blowing requirements within the conventional height range of users. In addition, the deflector for up and down air sweeping is in the humid and hot environment of the kitchen. When cold air blows out from the air outlet, it is easy to cause condensation on the deflector.

[0079] The following will be combined with Figures 1 to 13 , to describe the embodiments of the present utility model.

[0080] According to an embodiment of the present utility model, on the one hand, an air outlet system is provided, including a body 1, a first air guiding structure, a second air guiding structure, and a third air guiding structure.

[0081] Among them, the body 1 has an air inlet and an air outlet. The air inlet is adapted to communicate with the volute outlet of the evaporator assembly, and the air outlet extends in a direction parallel to the length direction of the range hood; the first air guiding structure is used to divide the interior of the body 1 into multiple chambers, and each chamber communicates with the air inlet and the air outlet; the second air guiding structure is arranged at the air outlet and is used to guide the air flow blown out from each chamber towards the front side; the third air guiding structure is arranged at the air outlet and is used for up and down air sweeping.

[0082] In this embodiment, the first air guiding structure divides the interior of the body 1 into multiple chambers, thereby realizing the distribution of the air volume in the horizontal area. The second air guiding structure guides the air flow blown out from each chamber towards the front side, preventing the air from blowing obliquely to one side and ensuring that the third air guiding structure can effectively guide the air. The third air guiding structure sweeps the air up and down, enabling a relatively large air supply range in the longitudinal direction and meeting the air supply requirements within the conventional height range of users. Therefore, no matter where the user is in the cooking area, they can be blown by the air, meeting the user's requirements for air feeling comfort.

[0083] In one embodiment, as Figure 6As shown, the second flow guiding structure includes an orifice plate 2, and the orifice plate 2 is provided with a plurality of flow guiding holes 201.

[0084] In this embodiment, the second flow guiding structure includes an orifice plate 2, and the orifice plate 2 is provided with a plurality of flow guiding holes 201. The structure of the second flow guiding structure is simple, and it can effectively guide the air flow blown out from each chamber forward, changing the direction of the air flow blown out from each chamber.

[0085] In one embodiment, the orifice plate 2 is arranged at the rear side of the third flow guiding structure, as Figure 7 shown, from back to front, the flow guiding holes 201 are inclined upward.

[0086] In this embodiment, the orifice plate 2 is arranged at the rear side of the third flow guiding structure. The air flow blown out from each chamber is first guided forward through the flow guiding holes 201 on the orifice plate 2. From back to front, the flow guiding holes 201 are inclined upward, which can effectively ensure that the air flow blown out through the flow guiding holes 201 can blow onto the third flow guiding structure, so as to ensure that the third flow guiding structure can effectively control the longitudinal range of the air flow blown out and meet the air supply requirements within the height range of conventional users.

[0087] In one embodiment, the aperture of the flow guiding hole 201 is d1, 2 mm ≤ d1 ≤ 15 mm; and / or, the inclination angle of the flow guiding hole 201 is a1, 3° ≤ a1 ≤ 15°; and / or, the hole pitch between two adjacent flow guiding holes 201 is d2, 1 mm ≤ d2 ≤ 2 mm; and / or, the thickness of the orifice plate 2 is d3, 5 mm ≤ d3 ≤ 7 mm.

[0088] In this embodiment, by setting the parameters of the aperture of the flow guiding hole 201, and / or the inclination angle of the flow guiding hole 201, and / or the hole pitch between the flow guiding holes 201, and / or the thickness of the orifice plate 2, more air flow can be blown onto the third flow guiding structure, so as to ensure that the third flow guiding structure can effectively control the longitudinal range of the air flow blown out and meet the air supply requirements within the height range of conventional users.

[0089] It should be noted that affected by the first flow guiding structure, the air flow blown out from each chamber is inclined to the left. Only when the air flow direction is normal to the third flow guiding structure can the third flow guiding structure effectively control the longitudinal range of the air flow blown out. By setting the parameters of the aperture of the flow guiding hole 201, and / or the inclination angle of the flow guiding hole 201, and / or the hole pitch between the flow guiding holes 201, and / or the thickness of the orifice plate 2, more air flow can be blown onto the third flow guiding structure.

[0090] It should be noted that in this embodiment, the shape of the flow guiding hole 201 is not limited, and specifically it can be various shapes such as circular, regular hexagon or square, etc.

[0091] In a preferred embodiment, the thickness of the orifice plate 2 is 6 mm.

[0092] In one embodiment, the third flow guiding structure includes at least one outer flow guiding plate 3, the outer flow guiding plate 3 is arc-shaped, and the outer flow guiding plate 3 is swingably arranged at the air outlet.

[0093] In this embodiment, the third flow guiding structure includes at least one outer flow guiding plate 3. The up-and-down swing of the outer flow guiding plate 3 can achieve up-and-down air sweeping, controlling the longitudinal range of the airflow blown out. Since the outer flow guiding plate 3 is arc-shaped, the airflow can be blown out more smoothly.

[0094] In one embodiment, as Figure 5 shown, there are two outer flow guiding plates 3, and they are spaced apart in the up-and-down direction.

[0095] In this embodiment, by arranging two outer flow guiding plates 3 and spacing them apart in the up-and-down direction, the longitudinal range of the airflow blown out can be further effectively controlled to meet the air supply requirements within the height range of ordinary users.

[0096] In one embodiment, the third flow guiding structure has a blowing-to-people mode in which the air sweeps within a first angle range and a wind-avoiding-people mode in which the air sweeps within a second angle range.

[0097] In this embodiment, by enabling the third flow guiding structure to have a blowing-to-people mode and a wind-avoiding-people mode, it can be selected according to user needs, improving the user experience.

[0098] In one embodiment, the first angle range means that the angle between the outer flow guiding plate 3 and the vertical plane is 50° - 90°, and the second angle range means that the angle between the outer flow guiding plate 3 and the vertical plane is 0° - 50°.

[0099] In this embodiment, when the outer flow guiding plate 3 swings between 0° and 50°, the airflow guided by the outer flow guiding plate 3 can be avoided from blowing towards the user. When the outer flow guiding plate 3 swings between 50° and 90°, the airflow guided by the outer flow guiding plate 3 longitudinally covers 1m - 1.9m, meeting the air supply requirements within the height range of ordinary users.

[0100] In one embodiment, the central angle corresponding to the outer flow guiding plate 3 is θ1, and 5° ≤ θ1 ≤ 20°.

[0101] In this embodiment, since the central angle corresponding to the outer flow guiding plate 3 is between 5° and 20°, it is convenient for the flexible swing of the outer flow guiding plate 3 and does not occupy a large space at the air outlet.

[0102] Specifically, in one embodiment, the central angle corresponding to the outer flow guiding plate 3 is 5°.

[0103] Specifically, in one embodiment, the central angle corresponding to the outer flow guiding plate 3 is 10°.

[0104] Specifically, in one embodiment, the central angle corresponding to the outer flow guiding plate 3 is 20°.

[0105] In one embodiment, as Figure 3 shown, the body 1 includes a main body portion 101 and an air outlet frame 102. The air outlet frame 102 is in communication with the outlet of the main body portion 101. The first flow guiding structure is disposed within the main body portion 101, the second flow guiding structure is disposed at the outlet of the main body portion 101, and the third flow guiding structure is disposed within the air outlet frame 102. The outlet of the air outlet frame 102 constitutes the air outlet.

[0106] In this embodiment, since the third flow guiding structure is disposed within the air outlet frame 102, both sides of the flow guiding structure can be fully exposed to the wind, and condensation on the third flow guiding structure can be avoided.

[0107] In one embodiment, further referring to Figure 3 , the distance between the bottom of the air outlet frame 102 and the plane where the bottom of the outlet of the main body portion 101 is located is h1, and 5 mm ≤ h1 ≤ 20 mm.

[0108] In this embodiment, by lowering the bottom of the air outlet frame 102 by h1 relative to the bottom of the outlet of the main body portion 101, it can be ensured that the air flow blown from the bottom of the main body portion 101 can also blow onto the outer flow guiding plate 3, so as to ensure that the third flow guiding structure can effectively control the longitudinal range of the blown air flow.

[0109] Specifically, in one embodiment, the distance between the bottom of the air outlet frame 102 and the plane where the bottom of the outlet of the main body portion 101 is located is 5 mm.

[0110] Specifically, in one embodiment, the distance between the bottom of the air outlet frame 102 and the plane where the bottom of the outlet of the main body portion 101 is located is 15 mm.

[0111] Specifically, in one embodiment, the distance between the bottom of the air outlet frame 102 and the plane where the bottom of the outlet of the main body portion 101 is located is 20 mm.

[0112] In one embodiment, further referring to Figure 3 , the distance between the top of the air outlet frame 102 and the horizontal plane where the top of the outlet of the main body portion 101 is located is h2, and h2 = h1.

[0113] In this embodiment, by lowering the top of the air outlet frame 102 by h2 relative to the top of the outlet of the main body portion 101, it can be ensured that the air flow blown from the top of the main body portion 101 can blow onto the outer flow guiding plate 3, so as to ensure that the third flow guiding structure can effectively control the longitudinal range of the blown air flow.

[0114] In one embodiment, the top of the air outlet frame 102 is arc-shaped.

[0115] In this embodiment, since the top of the air outlet frame 102 is arc-shaped, the airflow blown out from the top of the main body 101 can be guided to make the airflow flow more smoothly, thereby reducing wind resistance.

[0116] In one embodiment, further reference is made to Figure 3 The angle between the tangent line of the top of the air outlet frame 102 at the point where it is connected to the outlet of the main body 101 and the horizontal plane is θ2, 10°≤θ2≤50°.

[0117] In this embodiment, by making the angle between the tangent line of the top of the air outlet frame 102 connected to the outlet of the main body 101 and the horizontal plane be between 10° and 50°, on the one hand, the airflow blown out from the top of the main body 101 can be guided to make the airflow flow smoother, and on the other hand, it will not interfere with the outer guide plate 3, so that both sides of the outer guide plate 3 can be fully and evenly received by the wind to avoid condensation.

[0118] Specifically in one embodiment, the angle between the tangent line of the top of the air outlet frame 102 at the point where it is connected to the outlet of the main body 101 and the horizontal plane is 10°.

[0119] Specifically in one embodiment, the angle between the tangent line of the top of the air outlet frame 102 at the point where it is connected to the outlet of the main body 101 and the horizontal plane is 30°.

[0120] Specifically in one embodiment, the angle between the tangent line of the top of the air outlet frame 102 at the point where it is connected to the outlet of the main body 101 and the horizontal plane is 50°.

[0121] like Figure 4 As shown, the air outlet system of this embodiment is simulated, and it can be seen that the upper and lower sides of the two outer guide plates 3 can be fully exposed to wind, which can prevent condensation on the outer guide plates 3.

[0122] In an alternative embodiment, the orifice plate 2 is arranged on the front side of the third flow guide structure, such as Figure 11 and Figure 12 From top to bottom, the inclination angles of the guide holes 201 are different.

[0123] In this embodiment, since the orifice plate 2 is arranged on the front side of the third air guide structure, the third air guide structure cannot supply air to the upper and lower directions of the human body. Therefore, the inclination angles of the air guide holes 201 are different from top to bottom to achieve air supply in the upper and lower ranges.

[0124] Specifically in one embodiment, Figure 12 As shown, from top to bottom, the angles between the guide holes 201 and the horizontal direction are 0°, 0°, 10°, 10°, 20°, 20°, 30°, 30°, 40°, and 40° respectively.

[0125] By simulating the air outlet system in which the orifice plate 2 is arranged on the front side of the third flow guiding structure and the inclination angles of the flow guiding holes 201 are different from top to bottom, it can be seen that the blowing range can cover the left and right cooking areas, and the blowing height can cover 1m - 1.9m.

[0126] In one embodiment, as Figure 2 shown, the main body 101 is provided with an air inlet chamber 103 facing the air inlet, and an air outlet chamber 104 communicating with the air inlet chamber 103. In the direction parallel to the length direction of the range hood, the length of the air outlet chamber 104 is greater than the length of the air inlet chamber 103, and the first flow guiding structure is arranged in the air outlet chamber 104.

[0127] In this embodiment, the air inlet chamber 103 faces the air inlet. Therefore, the cold air blown out from the volute outlet of the evaporator assembly first enters the air inlet chamber 103, and then flows to the air outlet chamber 104 and is blown out from the air outlet. Since the length of the air outlet chamber 104 is greater than the length of the air inlet chamber 103 in the direction parallel to the length direction of the range hood, the air outlet has a larger length, which can improve the air outlet range. By arranging the first flow guiding structure in the air outlet chamber 104, the air outlet uniformity at the air outlet can be improved, making the user feel more comfortable.

[0128] In one embodiment, the first flow guiding structure includes a plurality of inner flow guiding plates, and each flow guiding plate is provided with an opening to communicate each chamber, and the plurality of inner flow guiding plates make the distances of the outlets of each chamber equal or approximately equal.

[0129] In this embodiment, the plurality of inner flow guiding plates make the distances of the outlets of each chamber equal or approximately equal, which can further improve the air outlet uniformity at the air outlet, making the user feel more comfortable.

[0130] It should be explained that the distances of the outlets of each chamber being approximately equal specifically means that the distances of the outlets of each chamber do not differ much. For example, the difference between the distances of the outlets of each chamber is between 0 - 5mm.

[0131] In one embodiment, the air outlet chamber 104 has a first side wall 105 and a second side wall 106 arranged opposite to each other. The first side wall 105 is close to the evaporator assembly, and the second side wall 106 is far from the evaporator assembly. From the first side wall 105 to the second side wall 106, the plurality of inner flow guiding plates are successively the first inner flow guiding plate 4, the second inner flow guiding plate 5, the third inner flow guiding plate 6, and the fourth inner flow guiding plate 7.

[0132] In this embodiment, the first inner flow guiding plate 4, the second inner flow guiding plate 5, the third inner flow guiding plate 6, and the fourth inner flow guiding plate 7 divide the air outlet chamber 104 into five chambers, and all these five chambers can blow air, thereby achieving air outlet uniformity in the transverse direction.

[0133] Of course, in other alternative embodiments, the number of the inner flow deflectors can be set according to actual requirements.

[0134] In one embodiment, the starting end of the first inner flow deflector 4 is arranged on the first side wall 105, and the included angle between the tangent line at the starting end of the first inner flow deflector 4 and the first side wall 105 is α1, where 0° ≤ α1 ≤ 45°;

[0135] And / or, the central angle corresponding to the first inner flow deflector 4 is β1, where 45° ≤ β1 ≤ 90°;

[0136] And / or, the ratio of the opening area on the first inner flow deflector 4 to the area of the first inner flow deflector 4 is A1, where 20% ≤ A1 ≤ 30%;

[0137] And / or, the starting ends of the second inner flow deflector 5, the third inner flow deflector 6 and the fourth inner flow deflector 7 are arranged on the rear wall of the body 1, and the starting ends of the second inner flow deflector 5, the third inner flow deflector 6 and the fourth inner flow deflector 7 are tangent to the rear wall of the body 1;

[0138] And / or, the central angles corresponding to the second inner flow deflector 5, the third inner flow deflector 6 and the fourth inner flow deflector 7 are all 90°;

[0139] And / or, the ratio of the opening area on the second inner flow deflector 5 to the area of the second inner flow deflector 5 is A2, where 65% ≤ A2 ≤ 85%;

[0140] And / or, the ratio of the opening area on the third inner flow deflector 6 to the area of the third inner flow deflector 6 is A3, where 50% ≤ A3 ≤ 70%;

[0141] And / or, the ratio of the opening area on the fourth inner flow deflector 7 to the area of the fourth inner flow deflector 7 is A4, where 35% ≤ A4 ≤ 55%.

[0142] In this embodiment, by setting the opening areas of the respective inner flow deflectors, it is possible to ensure the uniformity of air outlet in the lateral direction. In addition, each inner flow deflector is arc-shaped, which can make the air flow more smooth and reduce the resistance of the air flow passing through.

[0143] Through the wind speed simulation of the air outlet system of this embodiment, it can be seen that the blowing range can cover the left and right cooking areas, and the blowing height can cover 1 m - 1.9 m.

[0144] According to an embodiment of the present invention, on the other hand, an air-conditioning range hood is also provided, as Figure 10 shown, which includes an air-conditioning module and the air outlet system provided in the above embodiment. Among them, the air-conditioning module includes an evaporator assembly; the air inlet of the air outlet system is communicated with the volute outlet of the evaporator assembly.

[0145] For this air-conditioning range hood, the first air guiding structure can distribute the air volume within the lateral area, the second air guiding structure guides the air flow blown out from each chamber forward, preventing the wind from blowing obliquely to one side, and the third air guiding structure performs up-and-down air sweeping, enabling a relatively large air supply range in the longitudinal direction to meet the air supply requirements within the height range of regular users. Therefore, no matter where the user is in the cooking area, they can be blown by the wind, meeting the user's requirement for wind feeling comfort.

[0146] Specifically, the evaporator assembly includes an evaporator 8 and an evaporation fan 9, and the volute of the evaporation fan 9 is communicated with the air inlet of the air outlet system.

[0147] Specifically, the air-conditioning module further includes a compressor 10, a condenser 11, and a condenser fan 12. The hot air flow generated by the condenser 11 is discharged into the air cabinet of the range hood, and the suction and exhaust fan is used to discharge the hot air flow and the oil fume gas to the outside through the exhaust pipe 13 together.

[0148] According to an embodiment of the present invention, on the other hand, a control method for an air-conditioning range hood is also provided, which is applied to the air-conditioning range hood provided in the above embodiment. The control method includes:

[0149] Obtain the temperature of the human body in the cooking area or the ambient temperature;

[0150] Execute the air-blowing-on-human mode or the air-avoiding-human mode according to the temperature of the human body in the cooking area or the ambient temperature. In the air-blowing-on-human mode, the second air guiding structure sweeps the air within the first angle range. In the air-avoiding-human mode, the second air guiding structure sweeps the air within the second angle range.

[0151] In this embodiment, obtaining the temperature of the human body in the cooking area or the ambient temperature and executing the air-blowing-on-human mode or the air-avoiding-human mode according to the temperature can make the human body more comfortable and improve the user experience.

[0152] Specifically, in one embodiment, as Figure 13 shown, when the temperature of the human body in the cooking area ≥ 36.7 °C, or the ambient temperature ≥ 30 °C, execute the air-blowing-on-human mode; when the temperature of the human body in the cooking area < 36.7 °C, or the ambient temperature < 30 °C, execute the air-avoiding-human mode.

[0153] In one embodiment, the first angle range means that the angle between the outer deflector 3 and the vertical plane is 50° - 90°, and the second angle range means that the angle between the outer deflector 3 and the vertical plane is 0° - 50°.

[0154] In this embodiment, when the outer deflector 3 swings between 0° and 50°, the air flow guided by the outer deflector 3 can be prevented from blowing towards the user. When the outer deflector 3 swings between 50° and 90°, the air flow guided by the outer deflector 3 longitudinally covers 1 m - 1.9 m, meeting the air supply requirements within the height range of regular users.

[0155] Although embodiments of the present utility model have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present utility model, and such modifications and variations all fall within the scope defined by this application.
