Description

Range hood's box structure and range hood

Technical Field

The utility model relates to a kitchen equipment, concretely relates to is a range hood's box structure, still relates to an use range hood that has aforementioned range hood's box structure.

Background

The range hood has become one of the indispensable kitchen household electrical appliances in modern families. The range hood works by utilizing the fluid dynamics principle, sucks and exhausts oil smoke through a centrifugal fan arranged in the range hood, and filters partial grease particles by using a filter screen. The centrifugal fan comprises a volute, an impeller arranged in the volute and a motor driving the impeller to rotate. When the impeller rotates, negative pressure suction is generated in the center of the fan, oil smoke below the range hood is sucked into the fan, accelerated by the fan and then collected and guided by the volute to be discharged out of a room.

Because the volume of the negative pressure cavity of the range hood determines the effect of oil smoke suction, the range hood in the prior art generally adopts a machine body with larger size to increase the volume of a negative pressure area. However, an excessively large fuselage may result in a large footprint of space above the cooktop.

In order to solve the above problems, a chinese utility model patent No. ZL202120561208.6 (publication No. CN 214891411U) discloses a cigarette making machine, comprising: casing, oil smoke passageway and collection petticoat pipe. The shell defines an air outlet machine cavity; one end of the oil smoke channel is communicated with the fan cavity, and the other end of the oil smoke channel is provided with a smoke suction port; the fume collecting hood is arranged at two sides of the fume channel, is rotatably connected with two sides of the lower part of the fume channel and comprises a fume collecting port; the fume collecting hood is attached to the side wall of the fume passage when the fume collecting hood is located at the first position, and the fume collecting hood is unfolded towards two sides of the fume passage to be communicated with the fume passage when the fume collecting hood is located at the second position.

Above-mentioned range hood sets up folding collection petticoat pipe respectively through the both ends at the casing, make the collection petticoat pipe expand under operating condition, utilize the collection mouth on the collection petticoat pipe to absorb the oil smoke of smoking mouth both sides, with enlarge the smoking scope, reduce the escape of range hood both sides oil smoke, improve oil absorption cigarette efficiency, and the collection petticoat pipe is folding under unoperated state, make the collection petticoat pipe attach and hide at the lateral wall of oil smoke passageway, with the size that reduces range hood, thereby reduce the occupation to the space above the cooking utensils.

Because the bottom wall of the smoke collecting hood (namely the second box body in the application) of the range hood is horizontal in the working state, the smoke collecting hood is easy to collide the head and the pot in the working state. Moreover, the smoke collecting port on the smoke collecting hood of the range hood is arranged at the front side of the smoke collecting hood and is far away from the kitchen range, which easily causes the oil smoke on the left side and the right side of the range hood to escape and influences the oil smoke suction effect of the range hood.
