Abstract
A blower for long-shaped air heater is composed of a centrifugal cyclone tube with a cylindrical external tube, a motor base in the middle of said external tube, a fan connected to the output shaft of said motor and consisting of several rectangular connecting sheets, and a turbine fan in said motor base. The centrifugal divergent rotation forward of wind power can be realized, when the wind power blowing device is used for an air duct with slender air outlet, the wind power rotating forward can be blown along the wall of the air duct in a rotating manner, and the defects that when a common blowing device is used for the air duct with slender tube shape, the air outlet at the near end is large and the air outlet at the far end is small can be solved. Meanwhile, the blowing device is not arranged in the air duct, so that the requirement of the slender structural design of the warm air blower can be met. The utility model has the characteristics of compact structure, simple to operate.
Description
The technical field is as follows:
the utility model relates to a blast apparatus suitable for elongate electric fan heater belongs to small household appliances neighborhood.
Background art:
the blowing device of the warm air blower in the prior art mostly adopts a structure that a motor drives a wind wheel or a fan blade to rotate, the wind wheel or the fan blade is arranged in an air duct, and the wind wheel or the fan blade faces a heating component arranged at an air outlet of the air duct. If the fan is installed at the end of the elongated tubular air duct, the defects that the air outlet of the proximal end of the elongated tubular air duct is large and the air outlet of the distal end of the elongated tubular air duct is small exist. The structure can not meet the design requirement of slender shape required by some heating electrical appliances.
The invention content is as follows:
the utility model discloses improve to above-mentioned current electric fan heater's blast apparatus's defect, provide a compact structure, simple to operate's blast apparatus who is applicable to slender electric fan heater.
The utility model discloses a realize through following technical scheme: a blower for long-shaped air heater is composed of a centrifugal cyclone tube with a cylindrical external tube, a motor base in the middle of said external tube, a fan connected to the output shaft of said motor and consisting of several rectangular connecting sheets, and a turbine fan in said motor base.
Furthermore, the rectangular connecting sheet is twisted, the included angle α between the motor seat connecting part of the rectangular connecting sheet and the diameter surface of the outer cylinder is 9-15 degrees, and the included angle β between the outer cylinder connecting part of the rectangular connecting sheet and the diameter surface of the outer cylinder is 25-35 degrees.
The utility model discloses a blast apparatus suitable for elongate electric fan heater is because the fan adopts turbofan, and wind blows to above-mentioned rectangle connection thin slice, and the centrifugation that can realize wind-force is dispersed rotatory forward for during the wind channel of elongate air-out, rotatory forward wind-force can be blown along the wind channel wall rotation, can solve when ordinary blast apparatus is used for the tubulose wind channel of elongate, the defect that the near-end air-out is big, the distal end air-out is little. Meanwhile, the blowing device is not arranged in the air duct, so that the requirement of the slender structural design of the warm air blower can be met. The utility model has the characteristics of compact structure, simple to operate.
Description of the drawings:
fig. 1 is a schematic structural diagram of a blowing device suitable for an elongated fan heater according to the present invention.
Fig. 2 is a schematic structural view of the reverse side of fig. 1.
FIG. 3 is a schematic diagram of the structure of the centrifugal cyclone tube.
