Definitions

  • the present invention relates to the field of a range hood and components thereof, and more particularly to a case for accommodating a volute.
  • a range hood is a kitchen appliance for cleaning kitchen environment.
  • the range hood is mounted above a cooker in the kitchen, is capable of quickly exhausting burning wastes of the cooker and oil fume harmful to the human body produced in cooking to the outdoors, reducing indoor pollution, and purifying indoor air, and has the safety guarantee function of gas proof and explosion proof.
  • a volute is an important component of the range hood, and generally consists of three parts: a front baffle, an enclosing board, and a rear baffle.
  • an air inlet is disposed on the front baffle, for taking in air.
  • air is taken in mainly from the air inlet on the front baffle.
  • the rear baffle generally also has an air inlet disposed thereon, since a connecting device connected to a case is usually disposed on one side of the rear baffle, and the connecting device is usually disposed between the rear baffle and a side wall of the case that the rear baffle faces, a poor air intake effect of the air inlet on the rear baffle is caused and noise is easily produced. Therefore, how to change the existing fixing mode of the volute to improve the effect of taking in air from both sides of the volute has always been a technical problem demanding prompt solution in this field.

  • the present invention may include providing an inlet, a portion or an opening in or on the respective element.
  • a recessed portion is disposed on at least one side wall of the case opposite to the enclosing board, and the recessed portion is recessed away from the enclosing board.
  • the side wall which according to the present invention is opposite to the enclosing board, may also be referred to as the side wall facing or being adjacent to the enclosing board.
  • the recessed portion is used for accommodating a corresponding protruding portion of the volute, and the protruding portion of the volute refers to a portion of the volute that protrudes from a plane where a region of the side wall other than the recessed portion is located. In this way, since the recessed portion is disposed, it is possible to enlarge a fan system without significantly increasing the volume of the case.
  • a recessed cavity of the recessed portion is of a cuboidal structure or a cubic structure or a cylindrical structure or a circular truncated conical structure or a columnar structure having a bow-shaped base.
  • a recessed cavity of the recessed portion fits a structure of the protruding portion of the volute accommodated therein. In this way, the material consumption of the recessed portion can be reduced and it is easier to fix the volute.
  • the side wall provided with the recessed portion and the volute are connected and fixed to each other through at least one connecting device.
  • the connecting device includes a first connecting portion and a second connecting portion.

  • the first connecting portion is attached to the front baffle or the rear baffle, and the second connecting portion is attached to the region of the side wall other than the recessed portion.
  • the first connecting portion is completely attached to the front baffle or the rear baffle. In this way, a better fixing effect can be achieved.
  • the first connecting portion is fixed to the volute by screw connection or riveting or welding or integral formation.
  • the production and manufacturing efficiency can be greatly improved.
  • the second connecting portion is fixed to the side wall by screw connection or riveting or welding.
  • the side wall provided with the recessed portion and the volute are connected and fixed to each other through at least one V-shaped fixing sheet.
  • the V-shaped fixing sheet includes two fixing sheet bodies, and an angle between the two fixing sheet bodies is an acute angle. Ends of the V-shaped fixing sheet in an opening direction are connected to the front baffle or the rear baffle.
  • One fixing sheet body of the V-shaped fixing sheet is attached to the region of the side wall other than the recessed portion. A better fixing effect can be achieved by using the V-shaped fixing sheet for fixing.
  • the case includes a U-shaped cover, and the air outlet and the recessed portion are both disposed on the U-shaped cover.
  • the recessed portion can be manufactured conveniently, so as to improve the production efficiency.
  • the recessed portions are respectively symmetrically disposed on two side walls of the case opposite to the enclosing board.
  • the two side walls are preferably opposite side walls of the case. In this way, the overall structure of the case is more aesthetic.
  • an air inlet is also disposed on the rear baffle.
