Description

Technical Field

[0001] The invention relates to the field of blower fans, and in particular to a radial twin-turbocharged blower and a duct blower. Background Art

[0002] In addition to the traditional air conditioning or heating methods, there are also new small heaters for indoor heating. However, the wind force of the small heaters on the market is relatively small, and the effect of use is not very optimistic due to their size limitations. In view of this, the present invention comes into being. Summary of the invention

[0003] In view of the above situation, the present invention primarily solves the technical problem that the wind power of small blowers or small fans in the prior art is insufficient. To this end, the present invention first aims to provide a radial twin-turbocharged blower, characterized in that it includes:

[0004] A housing, wherein a first housing air inlet and a second housing air inlet are relatively arranged on the housing, and the housing is also provided with a fan air outlet;

[0005] a drive motor, the drive motor being disposed in the housing, the drive motor having a drive shaft penetrating the drive motor, and two ends of the drive shaft corresponding to the first housing air inlet and the second housing air inlet respectively; and

[0006] A first helical impeller and a second helical impeller, wherein the first helical impeller is installed in the air inlet of the first shell through the driving shaft, and the second helical impeller is installed in the air inlet of the second shell through the driving shaft, and the impeller spiral directions of the first helical impeller and the second helical impeller are opposite.

[0007] The beneficial effects of the radial twin-turbocharged fan of the present invention are:

[0008] The present invention arranges a bidirectional spiral impeller, wherein the spiral directions of the first spiral impeller and the second spiral impeller are opposite; the first spiral impeller and the second spiral impeller are respectively arranged at both ends of the driving shaft of the driving motor, so as to realize one motor with two impellers; the effect of double turbocharging is achieved, the weight and wind force are increased, and the wind pressure at the fan outlet of the shell is increased.

[0009] Furthermore, a mounting plate is provided in the housing, and the drive motor is mounted in the housing through the mounting plate. Since the motor is blown in both directions by the first helical impeller and the second helical impeller, in order to ensure that the force caused by the wind flow does not affect the stability of the motor, the drive motor is mounted in the middle position of the housing through the mounting plate.

[0010] Furthermore, the mounting plate divides the cavity of the housing into a first cavity and a second cavity; the air inlet of the first housing and the air outlet of the fan are connected to the first cavity, and the air inlet of the second housing and the air outlet of the fan are connected to the second cavity. If the partition is not used to separate them, the wind flow collision between the first spiral impeller and the second spiral impeller will affect the air intake. The mounting plate separates the wind flow collision between the first spiral impeller and the second spiral impeller, which can improve the air intake efficiency.

[0011] The present invention also provides a radial twin-turbocharged duct fan based on the fan, characterized in that it comprises a box body and the above-mentioned radial twin-turbocharged fan; the box body is provided with a box body air outlet and a box body air inlet, and an air duct is provided between the fan outlet and the body air outlet of the fan.

[0014] Furthermore, the box air outlet includes a box cold air outlet and a box hot air outlet; a heating module is installed on the hot air outlet. The heating module can heat the airflow to achieve the effect of heating, and play the role of an electric heating fan. At the same time, the cold air outlet and the hot air outlet can be used selectively to achieve diversified functions.

[0015] Furthermore, the number of the hot air outlets of the box is two, and the number of the cold air outlets of the box is one; the cold air outlet of the box is located between the two hot air outlets of the box. This arrangement can combine more air outlet modes, further diversifying the functions.

[0016] Furthermore, a wind shield is provided in the air duct, and the wind shield can selectively cover the hot air outlet and the cold air outlet of the box through a rotating mechanism. The wind shield cooperates with the hot air outlet and the cold air outlet of the box to realize the switching of the cold air / hot air function.

[0017] Furthermore, the rotating mechanism includes a rotating shaft, a rotating motor and a mounting frame, wherein the mounting frame is mounted on the rotating shaft, the rotating shaft is vertically arranged in the air duct, the rotating motor drives the rotating shaft, and the windshield is mounted on the mounting frame. The rotating shaft is driven by the rotating motor to achieve an automatic control effect.

[0018] Furthermore, the air duct is a circular air duct having a first air duct opening and a second air duct opening; the first air duct opening is connected to the fan air outlet, and the second air duct opening is connected to the box air outlet. The fan exhaust enters the circular air duct to form a static pressure state, which is conducive to stable air outlet.
