Description

Technical Field

[0001] This utility model relates to the field of range hood technology, and in particular to a dual-side air intake range hood. Background Technology

[0002] Range hoods are essential kitchen appliances. Traditional side-draft range hoods typically have the air inlet facing the center of the stove, limiting their lateral coverage. When the stove is wide or there's a significant distance between two stovetops, the horizontal distance between the side edges and the air inlet increases, resulting in a significant decrease in suction power. With central air intake, the negative pressure center is concentrated in the middle, easily creating suction blind spots on the sides. When fumes rise from the sides of the stove, they must overcome air resistance to move towards the center. If they encounter a person blocking the airflow (such as a user standing in front of the stove), the airflow will be disturbed, creating vortices and exacerbating the escape of fumes. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a dual-sided air intake range hood to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a dual-intake range hood, comprising a body with a trapezoidal structure that is wider at the top and narrower at the bottom in its longitudinal cross-section. Dual-intake fans are installed on the inner wall of the body, with two air inlets on the left and right sides of each fan. The air outlet pipes of the dual-intake fans are fixed to the top of the body. An air outlet corresponding to the position of the air outlet pipe is opened on the top of the body. A transition pipe is provided at the air outlet position on the top of the body, and a connecting pipe is provided at the top of the transition pipe. A fume extraction port is provided on the front wall of the body. A left-side grease separation net, a middle grease separation net, and a right-side grease separation net are movably arranged from left to right within the body, resting against the inner edge of the fume extraction port.

[0005] Furthermore, the bottom left and / or right side of the dual-inlet fan is connected to an oil drip pipe, which is connected to an oil guide hose to guide the grease to the bottom of the machine body.

[0006] Furthermore, a hanging device is fixed to the side wall of the machine body, and a fastener is inserted into the hanging device. The oil guide hose is located in the space between the fastener and the hanging device.

[0007] Furthermore, the fastener includes a fastening part with a U-shaped cross-section, and insert plates are respectively provided at both ends of the fastening part. The hanger is provided with a T-shaped mounting groove, and the fastener is inserted into the mounting groove for connection.

[0008] Furthermore, one or more oil drip holes are provided on one side of the bottom of the machine body, and an oil collection box is provided below the oil drip holes of the machine body.

[0009] Furthermore, the bottom of the machine body is provided with two symmetrically arranged hanging plates, the longitudinal section of the hanging plates is L-shaped, and the oil receiving box is provided with hanging ears on both sides, the hanging ears being adapted to the hanging plates for insertion and connection.

[0010] Furthermore, decorative cover positioning buckles are respectively provided on both sides of the transition tube at the top of the machine body. The two decorative cover positioning buckles are symmetrically arranged. The longitudinal cross-section of the decorative cover positioning buckle is L-shaped, and the decorative cover is inserted into the decorative cover positioning buckle.

[0011] Furthermore, the decorative cover has a U-shaped cross-section, with ear plates on both sides of its bottom, and the ear plates are inserted and connected to the positioning buckle of the decorative cover.

[0012] Furthermore, a stop post is provided on the top rear side of the body to limit the decorative cover.

[0013] Beneficial effects

[0014] Compared to existing technologies, this invention has at least the following advantages: A dual-intake fan, located inside the machine body with air intakes on both the left and right sides, creates an internal negative pressure space during operation. This allows oil fumes to enter the fan evenly through the holes in the left, middle, and right grease separation meshes. Compared to traditional range hoods, this invention has a wider absorption range, increases the lateral coverage area, shortens the oil fume intake path, improves suction on both sides, and reduces diffusion. This creates an airflow that converges from both sides towards the center above the stove, reducing oil fume escape. Even when a person blocks the central area, the side intakes still maintain suction power and can still capture oil fumes, preventing diffusion caused by central obstruction. The left, middle, and right grease separation meshes lean against the inner edge of the fume inlet under their own weight, requiring no fasteners and facilitating disassembly.
