Description

Technical Field

[0001] This utility model relates to the field of range hood technology, specifically to an air intake assembly and a range hood. Background Technology

[0002] Range hoods are positioned above kitchen cooktops to extract and exhaust cooking fumes generated during cooking. Typically, a range hood panel has an air intake. When the fan is activated, the cooking fumes are drawn into the air duct of the collection box. Because the panel has a sloping section, over time, grease accumulates on this section and flows downwards. Since the air intake is located on this sloping section, the grease drips down onto the cooktop as it flows through it. In related technologies, an oil guide is installed on the back of the panel to guide the grease from the upper edge of the air intake, preventing it from dripping onto the outside of the range hood. However, the connection stability between the oil guide and the panel is poor, leading to unstable installation. Utility Model Content

[0014] Compared with the prior art, the air intake assembly of this utility model has the following advantages:

[0015] 1. When the air intake assembly of this utility model is applied to a range hood, the oil guide can guide the oil on the upper edge of the air intake and direct it to the rear side of the air intake panel. This prevents the oil flowing down the back of the air intake panel towards the air intake from dripping directly out of the air intake, thus ensuring the cleanliness of the stovetop. The air guide can guide the airflow entering the air collection chamber through the air intake, allowing the airflow to turn and flow upward more quickly and smoothly after entering the air collection chamber, reducing the velocity loss of the airflow when it first enters the air collection chamber and preventing the airflow from becoming turbulent after entering the air collection chamber. The decorative parts can cover and decorate the left and right ends of the air intake, so that when users look at the left and right ends of the air intake, they see the decorative parts instead of directly seeing the inside of the air collection chamber, thereby improving the user's visual experience of the range hood.

[0016] 2.

[0028] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0029] This utility model discloses an air intake assembly for a range hood. Please refer to [link / reference]. Figures 1 to 5 The air intake assembly proposed in this utility model includes an air intake panel 1, an oil guide 2, an air guide 3, and a decorative component 4. The air intake panel 1 is provided with an air intake 11. The oil guide 2 is located on the back of the air intake panel 1 and at the upper edge of the air intake 11, and is used to guide the oil at the upper edge of the air intake 11 and guide it to the rear side of the air intake panel 1. The air guide 3 is located on the back of the air intake panel 1 and at the lower edge of the air intake 11, and is used to guide the airflow entering through the air intake 11. There are two decorative components 4, which are located on the back of the air intake panel 1 and on the left and right sides of the air intake 11. The decorative components 4 are provided with slots 41 and support positions 42. The two ends of the oil guide 2 are respectively inserted into the slots 41 on the corresponding sides, and the two ends of the air guide 3 are respectively supported on the support positions 42 on the corresponding sides.

[0030] In this embodiment, when the suction panel 1 is applied to the range hood, the side of the suction panel 1 facing the user is the front, and the other side is the back. The air inlet 11 extends along the width direction of the suction panel 1, that is, it extends in the left-right direction. The range hood also includes a housing 01 and an air collection box assembly 02. The housing 01 has the suction panel 1 and an air collection chamber. The air inlet 11 communicates with the air collection chamber. The air collection box assembly 02 is installed on the housing 01 and has an exhaust chamber that communicates with the air collection chamber. The exhaust chamber is located above the air collection chamber. After the external airflow enters the air collection chamber through the air inlet 11, it turns upward and flows towards the exhaust chamber.

[0031] The length of the oil guide 2 corresponds to the length of the air intake 11. The oil guide 2 can guide the oil on the upper edge of the air intake 11 and direct it to the back side of the air intake panel 1, thereby preventing the oil flowing down the back of the air intake panel 1 to the air intake 11 from dripping directly out of the air intake 11, so as to ensure that the stove is clean and tidy.

[0032] The length of the air guide 3 corresponds to the length of the air inlet 11. The air guide 3 can guide the airflow that enters the air collection chamber through the air inlet 11, so that the airflow can turn and flow upward more quickly and smoothly after entering the air collection chamber, reducing the flow rate loss when the airflow first enters the air collection chamber and preventing the airflow from becoming turbulent after entering the air collection chamber.

[0033] The decorative piece 4 can cover the left and right ends of the air intake 11, so that when users look at the left and right ends of the air intake 11, they see the decorative piece 4 instead of directly seeing the inside of the air collection cavity, thereby improving the user's visual experience of the range hood.

[0034] By inserting both ends of the oil guide 2 into the slots 41 of the two decorative pieces 4 respectively, the two ends of the oil guide 2 can be connected to the two decorative pieces 4 respectively. By supporting both ends of the air guide 3 on the support positions 42 of the two decorative pieces 4 respectively, the two ends of the air guide 3 can be connected to the two decorative pieces 4 respectively. After the oil guide 2 and the air guide 3 are installed in place, the two decorative pieces 4 are positioned by the oil guide 2 and the air guide 3, which can ensure that the installation height of the decorative pieces 4 on both sides is consistent.

[0035] The air intake assembly of this utility model, such as Figures 2 to 5 As shown, the oil guide 2 has an oil guide surface 21 and a first connecting surface 22. The first connecting surface 22 is connected to the upper edge of the air intake 11. The oil guide surface 21 extends to the rear side of the air intake panel 1. The decorative part 4 is provided with a pressure plate 43, which is pressed onto the upper surface of the oil guide surface 21 on the corresponding side.

[0036] The first connecting surface 22 is connected to the inner side of the suction panel 1, and the oil guiding surface 21 is connected to the lower edge of the first connecting surface 22 and extends obliquely downward and backward. The pressure plates 43 of the two decorative pieces 4 respectively abut against the upper surfaces at both ends of the oil guiding surface 21, thereby limiting the oil guiding surface 21 and ensuring the stability of its shape and position, so as to further improve the installation stability of the oil guiding piece 2. Oil droplets dripping from above the suction port 11 can drip onto the oil guiding surface 21 and then flow along the oil guiding surface 21 to the lower air guide plate.

[0037] The air intake assembly of this utility model, such as Figures 4 to 5 As shown, the upper edge of the air intake 11 is provided with an upper flange 111 and a first connecting plate 112. The upper flange 111 is inclined downward from front to back. The first connecting plate 112 is connected to the lower edge of the upper flange 111 and is inclined upward from front to back. The first connecting surface 22 is connected to the first connecting plate 112. The two ends of the first connecting surface 22 and the first connecting plate 112 are respectively inserted into the slots 41 on the corresponding sides. The slope of the oil guiding surface 21 is the same as the slope of the upper flange 111.

[0038] The first connecting plate 112 is connected to the first connecting surface 22 of the oil guide 2. The slope of the oil guide surface 21 is the same as the slope of the upper flange 111, so that the lower surface of the upper flange 111 and the first connecting surface 22 of the oil guide surface 21 can be connected in the same direction. After the oil on the suction panel 1 flows to the upper flange 111, it is stored in the gap between the upper flange 111 and the first connecting surface 22. After a certain amount is stored, it flows along the first connecting surface 22 and falls into the inner side of the suction port 111.

[0039] The air intake assembly of this utility model, such as Figure 2 As shown, the oil guiding surface 21 is provided with an air passage hole 211. The air passage hole 211 allows part of the airflow passing through the air intake 11 to pass through the oil guiding surface 21, so that this part of the airflow can flow directly upward, reducing the resistance of the oil guiding surface 21 to the airflow passing through the air intake 11.

[0040] The air intake assembly of this utility model, such as Figures 2 to 5 As shown, the lower edge of the air intake 11 is provided with a lower flange 113 and a second connecting plate 114. The lower flange 113 is inclined upward from front to back. The second connecting plate 114 is located on the upper edge of the lower flange 113 and is inclined downward from front to back. The air guide 3 has a second connecting surface 31 that matches the inclination of the second connecting plate 114. The second connecting surface 31 is connected to the second connecting plate 114. The part of the air guide 3 located behind the second connecting surface 31 is inclined upward from front to back.

[0041] The second connecting plate 114 is connected to the second connecting surface 31, which increases the connection area between the air guide 3 and the lower edge of the air intake 11, thereby improving the connection stability of the air guide 3 on the back of the air intake panel 1. The slope of the second connecting surface 31 and the second connecting plate 114 are adapted to allow the air guide 3 to transition more smoothly and naturally with the lower edge of the air intake 11. As a result, the airflow flowing into the air intake 11 can flow more naturally through the air guide 3 after passing through the second connecting plate 114, so that it can flow more smoothly into the exhaust chamber of the range hood under the guiding effect of the air guide 3.

[0042] The air intake assembly of this utility model, such as Figure 5 As shown, the second connecting surface 31 is connected to the lower surface of the second connecting plate 114. If the second connecting surface 31 is connected to the upper surface of the second connecting plate 114, a gap will be formed between the second connecting surface 31 and the second connecting plate 114 facing outwards from the air intake 11. When external airflow flows into the air intake 11, some airflow will flow into this gap, causing noise or airflow turbulence. However, if the second connecting surface 31 is connected to the lower surface of the second connecting plate 114, the gap between the second connecting surface 31 and the second connecting plate 114 will be blocked by the lower flange 113, so that external airflow will not enter the gap when flowing through the air intake 11. The lower flange 113 and the second connecting plate 114 are integrally formed, so no gap will be formed between the lower flange 113 and the second connecting plate 114. In this way, the airflow flowing through the air intake 11 can be avoided, thereby ensuring airflow stability and reducing noise generation.

[0043] The air intake assembly of this utility model, such as Figure 5 As shown, the air guide 3 has an oil drip hole 32 on the part located behind the second connecting surface 31. Oil droplets will drip from the air collecting cavity onto the air guide 3, and the oil guided by the oil guide 2 will also flow onto the air guide 3. The oil drip hole 32 allows the oil collected by the air guide 3 to pass through, so that the oil can continue to flow below the air guide 3 under the action of gravity, thereby preventing the oil from accumulating on the air guide 3 and flowing out of the air intake 11, thus improving the guiding effect of the oil.

[0044] The air intake assembly of this utility model, such as Figure 3 As shown, the decorative component 4 includes a body 44 and a third connecting surface 45. The third connecting surface 45 is connected to the back of the suction panel 1. The third connecting surface 45 has an arc shape that matches the corresponding end of the suction port 11. The body 44 extends from the arc shape in a direction away from the third connecting surface 45. The body 44 has a rectifying groove 441 that is recessed in a direction away from the suction port 11. The rectifying groove 441 has a rectifying hole 442.

[0045] The third connecting surface 45 increases the connection area between the decorative element 4 and the suction panel 1, thereby improving the connection stability of the decorative element 4 on the suction panel 1. The two ends of the suction port 11 are arc-shaped, and the arc of the third connecting surface 45 matches the arc of the suction port 11. This ensures both the connection area between the third connecting surface 45 and the suction panel 1 and prevents the third connecting surface 45 from blocking the suction port 11. When external airflow passes through the decorative element 4, it first flows into the air-regulating groove 441. The air-regulating groove 441 acts as a transition guide for the airflow passing through the decorative element 4, maintaining a stable flow direction and velocity, and preventing airflow turbulence. The air-regulating hole 442 allows some of the airflow passing through the air-regulating groove 441 to pass through, allowing the airflow to directly flow into the air collection chamber through the air-regulating hole 442. This further reduces the influence of the decorative element 4 on the airflow at both ends of the suction port 11, thereby improving the suction effect of the suction port 11.

[0046] The air intake assembly of this utility model, such as Figure 3 As shown, slot 41 is located on the side of the body 44 near the air intake 11, and support 42 extends along the lower edge of the body 44. Positioning slot 41 on the side of the body 44 near the air intake 11, that is, near the third connecting surface 45, allows the insertion position of the oil guide 2 and the decorative part 4 to be as close as possible to the air intake 11 and the air intake panel 1, thus making the connection between the air intake panel 1, the oil guide 2, and the decorative part 4 more compact and stable. The support 42 extends along the lower edge of the body 44, so that after the air guide 3 overlaps on the support 42, it avoids obstructing the decorative part 4, ensuring the decorative effect of the decorative part 4.

[0047] like Figure 6 As shown, this utility model also proposes a range hood that employs the air intake assembly described above, including a housing 01 and an air collection box assembly 02. The housing 01 has an air intake panel 1 and an air collection cavity. The air intake 11 communicates with the air collection cavity. The air collection box assembly 02 is mounted on the housing 01 and has an exhaust cavity that communicates with the air collection cavity. The exhaust cavity is located above the air collection cavity. After the external airflow enters the air collection cavity through the air intake 11, it turns upward and flows towards the exhaust cavity.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
