Detailed Description

Example 1

In order to make the technical problem, technical solution and beneficial effect solved by the present invention more clearly understood, the following description is combined with the accompanying drawings and embodiments, and it is right that the present invention further details the expense. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 and 2, a range hood with an inward-turning baffle comprises a body 1, a smoke collecting hood 3 provided with a smoke suction port 33 is mounted on the body 1, a baffle 4 is arranged in the body 1, a power mechanism 2, a driving rod 51 and a driven rod 52 are arranged in the body 1, and a driving rod fixing seat 31 and a driven rod fixing seat 32 are arranged on the inner side wall of the smoke collecting hood 3; two ends of the driving rod 51 are respectively and rotatably connected to the driving rod fixing seat 31 and the baffle 4, and two ends of the driven rod 52 are respectively and rotatably connected to the driven rod fixing seat 32 and the baffle 4; the driving rod 51, the baffle 4 and the driven rod 52 are connected to form a four-bar linkage; the power mechanism 2 is pivoted with the driving rod 51;

when the power mechanism 2 drives the driving rod 51 to rotate to the closed position, the baffle 4 rotates to the position flush with the inner surface of the smoke collecting cover 3 along with the rotation, and the smoke suction port 33 is closed; when the power mechanism 2 drives the driving rod 52 to rotate to the opening position, the baffle 4 turns over towards the inner side of the machine body 1 along with the separation of the smoke collecting cover 3, and the smoke suction port 33 is opened.

In fig. 1, the smoke collecting hood 3, the baffle 4, the driving rod 51 and the driven rod 52 form a four-bar linkage. The baffle 4 is opened and closed in the body. The range hood baffle 4 is turned inwards, so that the view of a user is not blocked during cooking. When the oil dripping device is used, the baffle 4 always moves inside the machine body, so that oil drops on the baffle cannot drip outside the machine body.

Fig. 2 is a schematic diagram showing a link mechanism to which the present invention is applied. The smoke collecting hood 3 can be regarded as a fixed rod, the baffle 4 can be regarded as a linkage rod, and the driving rod 51 and the driven rod 52 are added to form a linkage mechanism.

Example 2

This example is an improvement over example 1. The driving rod 51, the driven rod 52, the driven rod fixing seat 32 and the driving rod fixing seat 31 are respectively provided with a group at corresponding positions on two sides of the baffle plate 4 and the smoke collecting hood 3, and the power mechanism 2 is in transmission connection with the driving rod in one group. This arrangement can improve the stability of the baffle 4. Both ends at baffle 4 all set up connecting rod and fixing base, can let baffle 4 motion trail more level and smooth. Different from the baffle of formula of turning up, this scheme baffle is turned over in, and especially the higher user of height field of vision can not be sheltered from by baffle 4 when cooking. This lampblack absorber adopts simple four-bar linkage, because the formula baffle of turning over in is limited in the internal space, and when the baffle becomes the open mode, compare in the baffle of direct inside upset, four-bar linkage has provided bigger relative displacement for baffle 4 to smoking mouth 33 in limited space, makes the open area of smoking mouth bigger, and the amount of wind loss is little, and then the smoking is more smooth and easy.

Example 3

This example is an improvement over example 2. As shown in fig. 3 and 4, the power mechanism 2 includes an electric push rod 21 and a push rod fixing seat 11, the push rod fixing seat 11 is fixed on the inner wall of the machine body 1, one end of the electric push rod 21 is rotatably connected with one end of the driving rod 51, and the other end of the electric push rod 21 is rotatably connected with the push rod fixing seat 11.

When the electric push rod stretches, power support is provided for the rotation of the driving rod, so that the whole four-bar mechanism runs and is transited from relative translation to relative rotation.

The range hood further comprises a push rod connecting rod 22, one end of the push rod connecting rod 22 is connected with the driving rod 51 through a linkage device 6, and the other end of the push rod connecting rod 22 is rotatably connected with the electric push rod 21.

The linkage device 6 is a rotating shaft with a U-arc-shaped cross section, and the push rod connecting rod 22 and the driving rod 51 are provided with U-arc-shaped holes with the same size as the U-arc-shaped cross section on the rotating shaft.

The shaft at the joint with the push rod connecting rod 22 and the driving rod 51 is changed into a major arc arch, so that the linkage of the push rod connecting rod 22 and the driving rod 51 can be realized without occupying extra space.

Example 4

This example is an improvement over example 3. In this embodiment, the power mechanism 2 includes an electric push rod 21 and a push rod fixing seat 11, the push rod fixing seat 11 is fixed on the inner wall of the machine body 1, one end of the electric push rod 21 is rotatably connected with one end of the driving rod 51, and the other end of the electric push rod 21 is rotatably connected with the push rod fixing seat 11. The range hood further comprises a push rod connecting rod 22, one end of the push rod connecting rod 22 is connected with the driving rod 51 through a linkage device 6, and the other end of the push rod connecting rod 22 is rotatably connected with the electric push rod 21. The linkage device 6 is a limit hook arranged between the push rod connecting rod and the driving rod. This solution can be used when the existing conditions do not facilitate the cutting of the shaft. The push rod connecting rod 22 and the driving rod 51 may be provided with holes, and then a string penetrating through the holes may be used as a linkage, or the push rod connecting rod 22 and a part of the driving rod 51 may be directly bonded by a rigid material such as an iron plate, or linkage may be formed.

The inner wall side of the fume collecting hood 3 is provided with a sealing device which is correspondingly matched with the closed state position of the baffle 4. When the machine body 1 is closed, the sealing device on the inner wall side of the smoke collecting hood 3 just forms a closed structure with the baffle. The appearance of the device has an integral aesthetic feeling, and simultaneously, the oil smoke can be prevented from flowing backwards, so that the kitchen does not have peculiar smell.

Example 5

This example is an improvement over example 3. As shown in fig. 5, the four-bar linkage is a double crank mechanism and the driving link 51 and the driven link 52 have different lengths. The driving rod 51 and the driven rod 52 are not long, and have a double crank structure with non-long rods, so that the problem that the starting position is positioned at the dead point is solved due to the characteristic of no dead point. The motor fixing seat 34 is arranged beside the driving rod fixing seat 31 on the machine body 1, the worm gear speed reducing motor is installed on the motor fixing seat 34, and the worm gear speed reducing motor is in transmission connection with the driving rod 51.
