Detailed Description
The first embodiment is as follows:
referring to fig. 1, a range hood includes a housing 1 and a wind collecting cover 2, wherein a lampblack purification component is arranged inside the housing 1, and the lampblack purification component includes a filter screen 6.
Referring to fig. 1 and 2, an accommodating cavity 5 for accommodating the filter screen 6 is formed in the housing 1, an opening is formed in a surface of the housing 1 corresponding to the accommodating cavity 5, the opening is used for allowing the filter screen 6 to be inserted into the accommodating cavity 5 from the outside of the housing 1, a detachable cover plate 3 is arranged at the opening, and the cover plate 3 is used for covering the opening.
After opening apron 3, can pull out filter screen 6 from holding chamber 5, accomplish the washing of filter screen 6 and maintain the back, insert holding chamber 5 with clean filter screen 6 from the opening part in, cover apron 3 again can, easy operation is convenient, can greatly make things convenient for the washing and the maintenance work of filter screen 6.
Referring to fig. 3 and 4, in the present embodiment, a strip-shaped lower support frame 12 is installed in the housing 1 at the bottom of the accommodating chamber 5, and a strip-shaped upper support frame 14 is installed in the housing 1 at a position not at the top of the accommodating chamber 5, wherein the upper support frame 14 is parallel to the lower support frame 12. The lower support frame 12 and the upper support frame 14 are both slotted frames with the cross-sectional shape of C, and the notches of the upper support frame 14 and the lower support frame 12 are opposite. The upper support frame 14 and the lower support frame 12 have a guiding function, so that the filter screen 6 can be inserted into the housing 1 along a straight line, and the filter screen 6 can be positioned and supported, so that the filter screen 6 is stably kept in the accommodating cavity 5.
As shown in fig. 3, in this embodiment, a strip-shaped protruding portion 13 is disposed on the bottom surface of the lower support frame 12 along the length direction thereof, the width of the protruding portion 13 is smaller than that of the lower support frame 12, and when the filter screen 6 is inserted into the accommodating cavity 5, the bottom surface of the filter screen 6 is supported by the protruding portion 13, so that the filter screen 6 and the lower support frame 12 have a smaller contact area, thereby reducing the friction resistance of the filter screen 6 when sliding along the support frame, and making the filter screen 6 be inserted and pulled out more easily and laborsavingly. In addition, because the lampblack absorber uses the back for a long time, can accumulate more greasy dirt on the filter screen 6, the greasy dirt is piled up in the bottom of filter screen 6, probably makes the bottom of filter screen 6 and lower support 12 take place the adhesion, and the adhesion between the two can effectively be prevented with filter screen 6 and lower support 12 separation to swelling portion 13.
The surface of the ridge portion 13 in this embodiment is circular arc-shaped.
Referring to fig. 1, 2 and 6, in the embodiment, the connection mode between the cover plate 3 and the housing 1 is as follows: one end of the cover plate 3 is provided with a through hole 9, and the other end of the cover plate 3 is provided with a convex inserting part 10. The stop block 7 is not fixed below the opening on the shell 1, and a distance exists between the stop block 7 and the shell 1, so that a slot 8 for inserting the insertion part 10 of the cover plate 3 is formed, a threaded hole 11 is formed in the shell 1 and above the opening, a locking bolt 4 is arranged in a through hole 9 of the cover plate 3 in a penetrating mode, and the locking bolt 4 is screwed into the threaded hole 11. After inserting grafting portion 10 with the lower extreme of apron 3 into slot 8, the lower extreme of apron 3 is locked, penetrates locking bolt 4 and twists locking bolt 4 in screw hole 11 in to through-hole 9, can lock the upper end of apron 3 to can accomplish the installation of apron 3, after unscrewing locking bolt 4, can easily pull down apron 3, then can pull out filter screen 6.
As shown in fig. 5, in this embodiment, a first elastic sheet 15 is fixed at the front part of the frame of the filter screen 6, the first elastic sheet 15 protrudes forward, and the first elastic sheet 15 is used for providing elastic force in the front-back direction; and a second elastic sheet 16 is fixed at the top of the frame of the filter screen 6, the second elastic sheet 16 protrudes upwards, and the second elastic sheet 16 is used for providing elasticity in the up-and-down direction.
After the filter screen 6 is inserted into the accommodating cavity 5, the second elastic sheet 16 contacts with the upper support frame 14, and the generated elastic force enables the filter screen 6 to be pressed by the upper support frame 14, so that the stability and reliability of the inserted filter screen 6 are improved. Similarly, when the cover plate 3 is assembled, the first elastic sheet 15 is pressed, so that backward elasticity is generated on the filter screen 6, and the stability of the filter screen 6 in the front and back directions after being inserted is improved.
Example two:
referring to fig. 7, the difference between the present embodiment and the first embodiment is: the connection mode of the cover plate 3 and the housing 1 in this embodiment is different, specifically: in this embodiment, one side of the cover plate 3 is rotatably connected with the housing 1 through a hinge 17, a door lock 18 is installed on the other side of the cover plate 3, the cover plate 3 is locked by operating the door lock 18 after the cover plate 3 is covered, and the cover plate 3 can be opened in a rotating manner after the door lock 18 is opened.
Example three:
referring to fig. 8, the difference between the present embodiment and the first embodiment is: in this embodiment, the locking bolt 4 in the first embodiment is replaced with a magnet. As shown in fig. 8: a first magnet 19 is fixed to the housing 1 above the opening. When the inserting portion 10 at the lower end of the cover plate 3 is inserted into the inserting groove 8, the cover plate 3 is covered, and the first magnet 19 adsorbs the upper end of the cover plate 3, so that the cover plate 3 can be locked.
Example four:
referring to fig. 9, the present embodiment is different from the first embodiment in that: the cover plate 3 is fixed in this embodiment by magnetic means. Specifically, the method comprises the following steps: the first magnet 19 is not fixed on the housing 1 above the opening, the second magnet 20 is not fixed on the housing 1 below the opening, and after the cover plate 3 is covered, the first magnet 19 and the second magnet 20 respectively adsorb the upper end and the lower end of the cover plate 3, so that the cover plate 3 can be opened by pulling.
