Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, a gap-adjustable filter screen comprises an upper filter screen assembly 1 and a lower filter screen assembly 2, wherein the upper filter screen assembly 1 is adapted to be installed in the lower filter screen assembly 2, that is, the upper filter screen assembly 1 and the lower filter screen assembly 2 are detachable from each other, so that a user can clean residual grease conveniently. In this embodiment, the upper filter screen assembly 1 includes an upper frame 10 and upper blades 11, and the upper blades 11 are several and are uniformly distributed in the upper frame 10. The lower screen assembly 2 comprises a lower frame 20 and lower blades 21, and the lower blades 21 are a plurality of strips and are uniformly distributed in the lower frame 20. The upper filter screen component 1 and the lower filter screen component 2 are assembled, and then the plurality of upper blades 11 and the plurality of lower blades 21 are distributed in a crossed and staggered mode to form an oil smoke channel, so that the oil smoke separation effect is achieved.
As shown in fig. 2, 4 and 5, the upper filter screen assembly 1 is provided with an adjusting device 3 for adjusting a gap between the upper filter screen assembly 1 and the lower filter screen assembly 2, and the adjusting device 3 can control the grease separation capacity by increasing or decreasing the gap between the upper blade 11 and the lower blade 21 when the range hood is operated at a high range or a low range. The adjusting device 3 comprises a driving connecting rod 30 and two adjusting levers 31, in this embodiment, the number of the driving connecting rods 30 is one, and the number of the adjusting levers 31 is two, and the driving connecting rod 30 and the adjusting levers 31 can be installed on one side of the upper filter screen assembly 1 in the length direction, so as to drive the driving connecting rod 30 to move. Of course, in order to increase the stability of adjustment, the adjusting devices 3 may be provided in two groups, which are respectively symmetrically provided on two sides of the upper frame 10 in the length direction, so as to avoid the situation of improper adjustment. The top end of the adjusting lever 31 is hinged with the end of the driving connecting rod 30, the middle part of the adjusting lever 31 is hinged with the upper filter screen assembly 1, and the bottom end of the adjusting lever 31 is hinged with the lower filter screen assembly 2, so that a lever is formed. According to the lever principle, when the range hood runs at a low speed, as shown in fig. 4, the gap between the upper filter screen assembly 1 and the lower filter screen assembly 2 is in a normal state because the air intake is less, and at the moment, the gap between the upper filter screen assembly 1 and the lower filter screen assembly 2 is the minimum. When the lampblack absorber is in high-speed operation, promote through manual or automatic device drive connecting rod 30 moves to the right, as shown in fig. 5, drive connecting rod 30 drives adjusting lever 31 and rotates, adjusts filter screen assembly 1 more than lever 31 and swings right as the centre of a circle for on adjusting lever 31 with lower filter screen assembly 2 articulated one end move down, thereby the increase go up filter screen assembly 1 with clearance between the lower filter screen assembly 2 makes the intake increase, thereby realizes clearance adjustable purpose. Of course, the driving link 30 can be moved by a driver or a human hand, and the driver can be an existing electric device such as a motor or a lead screw or an air cylinder, as will be understood by those skilled in the art. When the clearance between the upper filter screen component 1 and the lower filter screen component 2 is smaller, the grease separation capacity can be improved, but when the large air volume is required, the clearance between the upper filter screen component and the lower filter screen component can be increased to increase the air volume, so that the adjustable function is realized.
Further, as shown in fig. 3, the adjusting lever 31 includes an upper lever 310 and a lower lever 311 connected to each other, an upper hinge hole 312 for hinging the driving link 30 is provided at the top end of the upper lever 310, a lower hinge hole 313 for hinging the lower screen assembly 2 is provided at the left end of the lower lever 311, a middle hinge hole 314 for hinging the upper screen assembly 1 is provided at the connection position between the upper lever 310 and the lower lever 311, the middle hinge hole 314 and the upper hinge hole 312 are located on the same straight line, the middle hinge hole 314 and the lower hinge hole 313 are located on the other straight line, that is, a straight line connecting the center of the middle hinge hole 314 and the center of the upper hinge hole 312 intersects a straight line connecting the center of the middle hinge hole 314 and the center of the lower hinge hole 313, and the two straight lines are not on the same straight line, so that the lower screen assembly 2 can be driven to move up and down by the left and right movement of the driving link 30, thereby achieving the purpose of adjusting the clearance. In this embodiment, the included angle between the upper lever 310 and the lower lever 311 is 120 °, and the included angle between the upper lever 310 and the lower lever 311 may be set according to the lengths of the two levers, and may be designed to be other angles, which should not be limited thereto.
A range hood, as shown in fig. 6, comprises a range hood body 4, a wind cabinet component 5, a control panel (not shown in the figure), and further comprises a filter screen with adjustable gap, as described above, the movement of a driving connecting rod 30 is controlled by the control panel, and other components are all of conventional design and are not described in detail herein, and will be understood by those skilled in the art.
The foregoing has described in detail preferred embodiments of the present invention.
