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 stoves 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 stovetop. Related technologies use grease guides on the back of the panel to guide the grease above the air intake, preventing it from dripping outside the range hood. However, these guides are entirely flat, resulting in poor grease drainage. Utility Model Content

[0005] According to one embodiment of the present invention, an air passage hole is provided on the oil guide surface, and the air passage hole extends from the first part to the second part.

[0006] According to one embodiment of the present invention, the upper edge of the air intake is provided with an upper flange and a first connecting plate.

The two decorative parts are disposed on the back of the air intake panel and located on the left and right sides of the air intake. The decorative parts are provided with slots and positioning plates. The two ends of the first part are respectively inserted into the slots on the corresponding sides, and the positioning plates are pressed on the corresponding sides of the first part.

[0008] According to one embodiment of the present invention, the decorative component includes a body and a third connecting surface. The third connecting surface is connected to the back of the air intake panel. The third connecting surface is provided with an arc shape that matches the corresponding end of the air intake. The body extends from the arc shape in a direction away from the third connecting surface. The body is provided with a rectifying groove that is recessed in a direction away from the air intake. The rectifying groove is provided with an air rectifying hole.

[0009] According to one embodiment of the present invention, the air intake assembly further includes an air guide, which is disposed on the back of the air intake panel and located at the lower edge of the air intake, for guiding the airflow entering through the air intake.

[0010] According to one embodiment of the present invention, the lower edge of the air intake is provided with a lower flange and a second connecting plate. The lower flange is inclined upward from front to back. The second connecting plate is located at the upper edge of the lower flange and is inclined downward from front to back. The air guide has a second connecting surface adapted to the inclination of the second connecting plate. The second connecting surface and the second connecting plate are connected.

[0013] This utility model also proposes a range hood that uses the above-mentioned air intake assembly, including a housing and an air collection box assembly. The housing has an air intake panel and an air collection cavity. The air intake is connected to the air collection cavity. The air collection box assembly is installed on the housing and has a smoke exhaust cavity that is connected to the air collection cavity.

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

[0015] When the suction port assembly of this utility model is applied to a range hood, the oil guide component can guide the oil on the upper edge of the suction port and direct it to the rear side of the suction panel. This prevents oil flowing down the back of the suction panel towards the suction port from dripping directly out of the suction port, ensuring a clean and tidy cooktop. After the oil flows to the oil guide surface of the oil guide component, it flows from the first part to the second part. Since the second part is arc-shaped, the oil will first make an upward parabolic motion when leaving the second part, and then make a downward parabolic motion. This increases the displacement of the oil towards the rear side of the suction panel after leaving the second part, thereby increasing the lateral distance between the oil and the suction port. This prevents oil from dripping out of the suction port or splashing out of the suction port after falling on other structures, thus improving the oil guiding effect of the oil guide component.

[0027] 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:

[0028] 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 and an oil guide component 2. The air intake panel 1 is provided with an air intake 11. The oil guide component 2 includes 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 oil guide surface 21 includes a first part 211 and a second part 212. The first part 211 is an inclined section, and the second part 212 is an arc section. The first part 211 is used to guide the oil from the upper edge of the air intake 11 to the second part 212, and the second part 212 is used to guide the oil to the rear side of the air intake panel 1.

[0029] 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.

[0030] 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.

[0031] After the oil flows to the oil guiding surface 21 of the oil guiding component 2, it will flow along the first part 211 to the second part 212. Since the second part 212 is arc-shaped, when the oil leaves the second part 212, it will first make an upward parabolic motion and then make a downward parabolic motion. In this way, the displacement of the oil towards the rear side of the suction panel 1 after leaving the second part 212 can be increased, thereby increasing the lateral distance between the oil and the suction port 11, so as to prevent the oil from dripping out of the suction port 11 or splashing out of the suction port 11 after falling on other structures, thereby improving the guiding effect of the oil guiding component 2 on the oil.

[0032] 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 213, which extends from the first part 211 to the second part 212. The air passage hole 213 allows part of the airflow passing through the suction port 11 to pass through the oil guiding surface 21, so that this part of the airflow can flow directly upward, thereby increasing the airflow rate at the suction port 11 and reducing the influence of the oil guiding surface 21 on the airflow rate of the suction port 11. The extension of the air passage hole 213 from the first part 211 to the second part 212 can make full use of the width of the oil guiding surface 21 to increase the size of the air passage hole 213, thereby effectively increasing the airflow rate of the air passage hole 213.

[0033] The air intake assembly of this utility model, such as Figure 4 and Figure 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. The first connecting plate 112 is inclined upward from front to back. The first connecting surface 22 is connected to the first connecting plate 112. The slope of the first part 211 is the same as the slope of the upper flange 111.

[0034] The first connecting plate 112 can increase the connection area between the upper edge of the air intake 11 and the oil guide 2, thereby improving the connection stability between the oil guide 2 and the air intake panel 1. The slope of the first part 211 is the same as the slope of the upper flange 111, so that the lower surface of the upper flange 111 and the lower surface of the first part 211 can be connected in the same direction. The oil on the air intake panel 1 flows to the upper edge of the air intake 11 and flows along the upper flange 111. It gathers at the gap between the upper flange 111 and the first part 211 of the oil guide 2. After a certain amount is gathered, it flows along the first part 211 and falls to the inside of the air intake 11.

[0035] The air intake assembly of this utility model, such as Figures 2 to 5As shown, the air intake assembly also includes decorative parts 3. There are two decorative parts 3. The two decorative parts 3 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 parts 3 are provided with slots 31 and positioning plates 32. The two ends of the first part 211 are respectively inserted into the slots 31 on the corresponding sides, and the positioning plates 32 are pressed on the corresponding sides of the first part 211.

[0036] Decorative parts 3 can obscure 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 decorative parts 3 instead of directly seeing the inside of the air collection chamber, thus improving the user's visual experience of the range hood. Inserting the two ends of the first part 211 into the slots 31 of the two decorative parts 3 respectively allows the oil guide 2 to establish a connection with the two decorative parts 3, thereby improving the installation stability of the oil guide 2 on the back of the air intake panel 1. The positioning plates 32 of the two decorative parts 3 abut against the upper surfaces of the two ends of the first part 211, thereby limiting the oil guide surface 21 and ensuring the stability of its shape and position, further improving the installation stability of the oil guide 2.

[0037] The air intake assembly of this utility model, such as Figure 2 and Figure 3 As shown, the decorative component 3 includes a body 33 and a third connecting surface 34. The third connecting surface 34 is connected to the back of the suction panel 1. The third connecting surface 34 has an arc shape that matches the corresponding end of the suction port 11. The body 33 extends from the arc shape in a direction away from the third connecting surface 34. The body 33 has a rectifying groove 331 that is recessed in a direction away from the suction port 11. The rectifying groove 331 has a rectifying hole 332.

[0038] The third connecting surface 34 increases the connection area between the decorative element 3 and the suction panel 1, thereby improving the connection stability of the decorative element 3 on the suction panel 1. The two ends of the suction port 11 are arc-shaped, and the arc of the third connecting surface 34 matches the arc of the suction port 11. This ensures both the connection area between the third connecting surface 34 and the suction panel 1 and prevents the third connecting surface 34 from blocking the suction port 11. When external airflow passes through the decorative element 3, it first flows into the air-regulating groove 331. The air-regulating groove 331 acts as a transition guide for the airflow passing through the decorative element 3, maintaining a stable flow direction and velocity, and preventing airflow turbulence. The air-regulating hole 332 allows some of the airflow passing through the air-regulating groove 331 to pass through, allowing the airflow to directly flow into the air collection chamber through the air-regulating hole 332. This further reduces the influence of the decorative element 3 on the airflow at both ends of the suction port 11, thereby improving the suction effect of the suction port 11.

[0039] The air intake assembly of this utility model, such as Figure 4 and Figure 5As shown, the air intake assembly also includes an air guide 4, which is located on the back of the air intake panel 1 and at the lower edge of the air intake 11. The air guide 4 guides the airflow entering through the air intake 11. The length of the air guide 4 corresponds to the length of the air intake 11. The air guide 4 guides the airflow entering the air collection chamber through the air intake 11, allowing the airflow to turn upwards more quickly and smoothly after entering the air collection chamber, reducing velocity loss when the airflow first enters the air collection chamber and preventing turbulence after entering the air collection chamber.

[0040] The air intake assembly of this utility model, such as Figure 4 and Figure 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 4 has a second connecting surface 41 that matches the inclination of the second connecting plate 114. The second connecting surface 41 and the second connecting plate 114 are connected. The part of the air guide 4 located behind the second connecting surface 41 is inclined upward from front to back.

[0041] The second connecting plate 114 is connected to the second connecting surface 41, which increases the connection area between the air guide 4 and the lower edge of the air intake 11, thereby improving the connection stability of the air guide 4 on the back of the air intake panel 1. The slope of the second connecting surface 41 and the second connecting plate 114 are adapted to allow the air guide 4 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 4 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 4.

[0042] The air intake assembly of this utility model, such as Figure 4 and Figure 5 As shown, the second connecting surface 41 is connected to the lower surface of the second connecting plate 114; the air guide 4 is provided with an oil drip hole 42 on the part located behind the second connecting surface 41.

[0043] If the second connecting surface 41 is connected to the upper surface of the second connecting plate 114, a gap will be formed between the second connecting surface 41 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 41 is connected to the lower surface of the second connecting plate 114, the gap between the second connecting surface 41 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.

[0044] Oil droplets will drip onto the air guide 4 inside the air collection chamber. The oil guided by the oil guide 2 will also flow onto the air guide 4. The oil drip hole 42 allows the oil collected by the air guide 4 to pass through, so that the oil can continue to flow below the air guide 4 under the action of gravity, thereby preventing the oil from accumulating on the air guide 4 and flowing out of the air intake 11, thus improving the guiding effect of the oil.

[0045] The air intake assembly of this utility model, such as Figure 2 and Figure 3 As shown, the decorative piece 3 has a support position 35, and the two ends of the air guide 4 are respectively supported on the support positions 35 on the corresponding sides. By supporting the two ends of the air guide 4 on the support positions 35 of the two decorative pieces 3, the decorative pieces 3 can also support the air guide 4, thereby improving the installation stability of the air guide 4 on the back of the suction panel 1.

[0046] like Figure 6 As shown, this utility model also proposes a range hood, employing 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, with an air intake 11 communicating with the air collection cavity. The air collection box assembly 02 is mounted on the housing 01 and has an exhaust cavity communicating with the air collection cavity. The exhaust cavity is located above the air collection cavity. After external airflow enters the air collection cavity through the air intake 11, it turns upward and flows towards the exhaust cavity.

[0047] 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.
