Problems solved by technology

[0003] First, the overall installation height of this top-suction range hood determines that the range hood is far away from the pot that produces the oil fume, and the negative pressure loss is relatively large; Split design, the overall design and appearance need to be improved; third, the smoke deflector after the range hood is installed has a certain height, which is not convenient for cleaning; fourth, the port of the smoke collecting hood has a filter, and the filter is easy to clean. Accumulated oil stains, and the smoke deflector covers the filter screen, so the rectifier plate must be disassembled when cleaning the filter screen, and the operation is more troublesome

Embodiment 1

[0042] Example 1, such as Figure 1 to Figure 5 As shown, the top suction range hood in this embodiment includes a body 10, a smoke collecting hood 100, a fan 3 and a rectifying plate 1. The smoke collecting hood 100 has an air inlet from bottom to top, and the rectifying plate 1 is facing the air inlet. The tuyere is set and forms an air inlet channel for oil fumes to pass between the inner cavity wall of the smoke collecting hood 100. The aforementioned machine body 10 is longitudinally arranged on the top of the smoke collecting hood 100, the fan 3 is set in the machine body 10, and the rectifying plate 1 can be raised and lowered. At the air inlet of the fume collecting hood 100.

[0043] The rectifying plate 1 is arranged at the air inlet of the smoke collecting hood 100 through a lifting mechanism. The lifting mechanism includes a motor 2, a push rod 22 and a support frame 23. The motor 2 is arranged in the body 10 with a hydraulic cylinder body 21, and the push rod 22 i...

Embodiment 2

[0051] Example 2, such as Figure 6 ~ Figure 11 As shown, a hinge 6 capable of adjusting the height is provided between the inner cavity wall of the smoke collecting hood 100 in this embodiment and the top surface of the rectifying plate 1 . Hinge 6 adopts damping hinge. There are three hinges 6, which are arranged on the front end and both sides of the rectifying plate 1 respectively. like Figure 8 As shown, wherein the hinge pieces 61 are connected by a damped hinge shaft 62 .

[0052] The air inlet of the smoke collecting hood 100 is located above the rectifying plate 1 and is provided with an oil screen 5. The bottom of the oil screen 5 is arranged obliquely downward from the front to the rear, and the rear end of the rectifying plate 1 protrudes from the oil screen 5 and is arranged obliquely downward. Correspondingly, the bottom of the rear end of the smoke collecting hood 100 is provided with an oil cup 4 that can collect oil droplets flowing down from the rectifyin...

Embodiment 3

[0054] Example 3, such as Figure 12 As shown, the smoke collecting hood 100 in this embodiment is also provided with an electric lifting mechanism, which includes a lifting motor 71, a fixed pulley 72 and a traction cable 73, the lifting motor 71 has a power output end; the fixed pulley 72 is two Each is located at the bottom of the body 10, and one end of the traction rope 73 is connected with the power output end of the lifting motor 71, and the other end is connected with the rectifying plate 1 by the fixed pulley 72. The traction cable 73 in this embodiment is preferably a steel wire.

[0055] The hinge in this embodiment may be a non-damping hinge. Refer to Example 2 for other structures. In this embodiment, the height adjustment of the rectifying plate 1 is realized by driving the lifting motor 71 .

Abstract

The invention relates to a ceiling-mounted range hood. The ceiling-mounted range hood comprises a machine body, a smoke collection cover, a fan and a rectifying plate, wherein the smoke collection cover is provided with an air inlet from bottom to top, the rectifying plate is right opposite to the air inlet and forms an air inlet passage which is used for the lampblack to pass through with the wall of an inner cavity of the smoke collection cover, the machine body is longitudinally arranged on the top of the smoke collection cover, the fan is arranged inside the machine body, and the ceiling-mounted range hood is characterized in that the rectifying plate is arranged in the air inlet of the smoke collection cover in an elevation manner. Compared with the prior art, the ceiling-mounted range hood has the advantages that through the elevation design of the rectifying plate, a concealing state, a working state and a washing state of the rectifying plate can be realized, and convenience in use can be realized.

Description

technical field [0001] The invention relates to a range hood, in particular to a kitchen top-suction range hood. Background technique [0002] Patent No. ZL200910096759.3 is a Chinese invention "A Range Hood with Smoke Guide" (authorized announcement number is CN101514823B). There is an air inlet on the top, and the smoke guide plate (also known as the rectifying plate) is set on the air inlet and keeps a predetermined distance from the smoke collection hood, so that there is a space for the oil fume to pass between the smoke guide plate and the smoke collection hood. The oil fume channel in this patent is fixed and cannot be moved, and has the following disadvantages: [0003] First, the overall installation height of this top-suction range hood determines that the range hood is far away from the pot that produces the oil fume, and the negative pressure loss is relatively large; Split design, the overall design and appearance need to be improved; third, the smoke deflecto...
