The present invention also provides a range hood.

Description

Technical Field

[0001] The invention relates to the field of kitchen appliances, and in particular to a rotating oil net for a range hood. Background Art

[0002] Composition of kitchen appliances: The fan system of the range hood is mainly composed of the motor, fan blades, wind cabinet, etc. The motor is the main component of the range hood and the power source of the range hood. It usually adopts a capacitor-operated single-phase asynchronous motor. The fan impeller of the range hood mostly adopts a centrifugal impeller, that is, the oil smoke is sucked in by a centrifugal exhaust fan and then discharged to the outside through the exhaust pipe. The motor drives the impeller to rotate at high speed, creating an air negative pressure area around the impeller, forcing the oil smoke on the stove to pass through the filter and the air inlet into the machine body and be discharged from the air outlet. At present, the oil filter nets of the range hoods on the market are all fixed, and the air flow flows into the impeller along the axial direction of the air inlet. The air flow inflow speed has certain limitations. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a rotating oil screen for a range hood and a range hood, which can make air flow in along the axis of the air inlet and in other directions at the same time to increase the air flow inflow.

[0004] A rotating oil net for a range hood comprises an oil net body, wherein the oil net body comprises a plurality of longitudinal partitions and a plurality of transverse partitions, wherein the longitudinal partitions and the transverse partitions intersect to form a plurality of air inlets, and the oil net body comprises an air inlet end and an air outlet end, wherein the longitudinal partitions and / or the transverse partitions are arranged obliquely, and the longitudinal partitions and / or the transverse partitions tend to the middle part of the oil net body in the process of extending from the air inlet end to the air outlet end.

[0005] A rotating oil screen for a range hood according to an embodiment of the present invention has at least the following beneficial effects: when the oil screen body rotates, the airflow flows along the air inlet end into the flow from the air outlet end to form a continuous airflow; since the longitudinal partitions and / or transverse partitions tend to the middle part of the oil screen body during their extension from the air inlet end to the air outlet end, the airflow around the oil screen body is forced to enter the air inlet when the oil screen body rotates, so that the airflow can flow in along directions other than the direction of the rotation axis of the oil screen body, thereby increasing the amount of airflow inflow.

[0006] According to some embodiments of a rotating oil screen for a range hood of the present invention, the surface of the oil screen body close to the air inlet end is a first arc surface, and the first arc surface is raised away from the air outlet end during the process of extending from the outer edge to the center. Therefore, the setting of the first arc surface makes it easier for the airflow around the oil screen body to flow into the air inlet when the oil screen body rotates.

[0007] According to some embodiments of the rotary oil screen for range hoods of the present invention, the longitudinal partition and / or the transverse partition have an inclination angle of 3° to 30°. The inclination angle of 3° to 30° is more conducive to the airflow flowing into the air inlet end.

[0008] The present invention also provides a range hood, comprising a body, wherein the body is provided with an oil smoke suction port, and a wind cabinet assembly is provided at the oil smoke suction port, the wind cabinet assembly comprises an air guide volute, a first drive motor and an impeller, the first drive motor is drivingly connected to the impeller, and the impeller is located in the air guide volute. The range hood also includes an oil net assembly, the oil net assembly includes a second drive motor and a fixed frame, the fixed frame is connected to the air guide volute, and the second drive motor is installed on the fixed frame. The oil net assembly also includes a rotating oil net for a range hood as described in any of the above embodiments, and the rotating oil net is drivingly connected to the second drive motor.

[0009] Therefore, when the range hood is working, air flows in from multiple directions at the air inlet end, and the air flow direction is wider. When the second drive motor drives the rotating oil net to rotate, a vortex airflow is formed, which increases the gas inflow speed and amount, and the range hood has a better effect.

[0010] According to some embodiments of a range hood according to the present invention, the oil net assembly also includes a nut, the second drive motor includes an output shaft, a connecting column is provided in the middle of the oil net body, a through connecting hole is provided on the connecting column, the output shaft passes through the connecting hole and is threadedly connected to the nut at the end, and the surface of the nut away from the connecting hole is a second arc surface, and the second arc surface protrudes in a direction away from the air outlet end.

[0011] According to some embodiments of a range hood of the present invention, a sink is provided in the middle of the oil net body, and the connecting column is provided in the middle of the sink. By providing the sink in the middle of the oil net body to separate the second drive motor located in the middle of the oil net body, the airflow is less affected by the drive device and the airflow flows faster.

[0012] According to some embodiments of a range hood of the present invention, a clamping block is provided on the outer periphery of the output shaft, a clamping slot is provided on the side of the connecting column close to the air outlet, and the clamping slot abuts against the clamping slot. Through the above arrangement, the output shaft and the rotating oil net transmit torque through the clamping slot and the clamping block, and the transmission between the second drive motor and the rotating oil net is more reliable and not easily affected by oil stains.

[0030] Among them, a rotating oil net for a range hood includes an oil net body, the oil net body includes a plurality of longitudinal partitions 110 and a plurality of transverse partitions 120, the longitudinal partitions 110 and the transverse partitions 120 intersect to form a plurality of air inlets 150, the oil net body includes an air inlet end and an air outlet end, the longitudinal partitions 110 and / or the transverse partitions 120 are inclined, and the longitudinal partitions 110 and / or the transverse partitions 120 tend to the middle part of the oil net body in the process of extending from the air inlet end to the air outlet end.

[0031] When the oil net body rotates, the airflow flows along the air inlet end into the air outlet end to form a continuous airflow. Since the longitudinal partition 110 and / or the transverse partition 120 tend to the middle part of the oil net body during the extension process from the air inlet end to the air outlet end, the airflow around the oil net body is forced to enter the air inlet 150 when the oil net body rotates, so that the airflow can flow in along other directions except the direction of the rotation axis of the oil net body, thereby increasing the amount of airflow inflow.

[0032] Specifically, the longitudinal partition plate 110 is arranged obliquely, and the longitudinal partition plate 110 tends to be toward the middle part of the oil net body during the process of extending from the air inlet end to the air outlet end.

[0033] The surface of the oil screen body close to the air inlet end is a first arc surface 101, and the first arc surface 101 protrudes away from the air outlet end during the process of extending from the outer edge to the center. The inclination angle of the longitudinal partition 110 is 3° to 30°. Specifically, the first arc surface 101 is a cut spherical curved surface. The inclination angle of the longitudinal partition 110 specifically refers to the angle between the longitudinal partition 110 and the central axis of the oil screen body.

[0034] Specifically, the oil net assembly also includes a nut 200, the second drive motor 310 includes an output shaft, a connecting column 140 is provided in the middle of the oil net body, and a through connecting hole 141 is provided on the connecting column 140.
