Description

Technical Field

[0001] This utility model relates to the field of internal circulation fan technology, and in particular to a dual-motor air outlet structure. Background Technology

[0002] A fan is a device that increases the pressure of gas and discharges it into a duct. It is commonly used in small household appliances such as gas appliances, fans, and air conditioners.

[0003] In existing fan structures, the fans are directly connected in parallel to the product's ductwork. When the main unit is running, the electrical components inside the main unit generate heat. If this heat is not dissipated in time, it causes the internal temperature of the product to rise, affecting the lifespan of the internal electrical components. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a dual-motor air outlet structure.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] The present invention discloses a dual-motor air outlet structure, comprising a lower motor, a motor bracket fixed to one end of the lower motor, and a lower impeller fixed to the other end of the lower motor; an upper motor is mounted on the motor bracket; an upper impeller is fixed to the output end of the upper motor; a housing is fitted around the upper impeller; and an air outlet and an air inlet are provided on the housing.

[0007] Furthermore, the housing is circular; one end face of the housing is open; the air inlet is circular; the upper impeller is a centrifugal impeller; the shaft of the centrifugal impeller, the shaft of the air inlet, and the shaft of the housing are all coaxially arranged.

[0008] With the above structure, the beneficial effects of this utility model are as follows: When installing the product with the dual-motor structure of this application, the motor bracket is fixed on the main unit of the product, and the lower impeller is installed on the circulating air duct structure of the product; the circulating air duct is set outside the main unit of the product; the lower motor drives the lower impeller to rotate, so that the air in the circulating air duct structure flows; the housing is installed inside the main unit of the product, and the air inlet of the housing is connected to the inside of the main unit of the product; the air outlet of the housing extends to the outside of the main unit of the product; the upper motor drives the upper impeller to rotate, so that the housing generates negative pressure, and the air inside the product enters the housing through the air inlet and is discharged to the outside of the main unit of the product through the air outlet; by integrating the lower motor and the upper motor on the motor bracket and placing them outside and inside the main unit of the product respectively, the rotation of the lower impeller provides power to the circulating air duct outside the main unit, and the rotating upper impeller discharges the hot air inside the main unit of the product, reducing the temperature of the electrical components inside the main unit and improving the service life. The two motors used to provide pressure for the circulating air and to cool the electrical components inside the main unit of the product are integrated into the same module, making the structure of the entire motor more compact.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figures 1 to 4 As shown, the dual-motor air outlet structure of this utility model includes a lower motor 5, a motor bracket 4 fixed to one end of the lower motor 5, and a lower impeller 6 fixed to the other end of the lower motor 5; an upper motor 2 is provided on the motor bracket 4; an upper impeller 3 is fixed to the output end of the upper motor 2; a housing 1 is fitted over the upper impeller 3; and an air outlet 101 and an air inlet 102 are provided on the housing 1.

[0018] The upper motor 2 and the lower motor 5 can be controlled by separate circuits and started according to actual usage requirements;

[0019] When installing the product with the dual-motor structure of this application, the motor bracket 4 is fixed on the main unit of the product, and the lower impeller 6 is installed into the circulating air duct structure of the product; the circulating air duct is set outside the main unit of the product; the lower motor 5 drives the lower impeller 6 to rotate, so that the air in the circulating air duct structure flows.

[0020] The housing 1 is installed inside the main unit of the product, and the air inlet 102 of the housing 1 is connected to the inside of the main unit of the product; the air outlet 101 of the housing 1 extends to the outside of the main unit of the product; the upper motor 2 drives the upper impeller 3 to rotate, which creates a negative pressure inside the housing 1. The air inside the product enters the housing 1 through the air inlet 102 and is discharged to the outside of the main unit of the product through the air outlet 101; the lower motor 5 and the upper motor 2, which are integrated on the motor bracket 4, are placed outside and inside the main unit of the product, respectively. Based on the rotation of the lower impeller 6 to provide power for the circulating air duct outside the main unit, the rotating upper impeller 3 is used to discharge the hot air inside the main unit of the product, reduce the temperature of the electrical components inside the main unit, and improve the service life. The two motors used to provide pressure for the circulating air and to cool the electrical components inside the main unit of the product are integrated into the same module, making the structure of the entire motor more compact.

[0021] In a preferred embodiment of this utility model, the housing 1 is circular; one end face of the housing 1 is open; the air inlet 102 is circular; the upper impeller 3 is a centrifugal impeller; the shaft of the centrifugal impeller, the shaft of the air inlet 102 and the shaft of the housing 1 are all coaxially arranged.

[0022] When the housing 1 is installed on the main body of the product, the open end face of the housing 1 fits against the inner surface of the main body of the product. A hole matching the upper motor 2 is opened on the side wall of the main body of the product, so that the upper motor 2 is embedded in the hole. By using the centrifugal impeller structure, the thickness of the part of this structure that extends into the main body of the product can be smaller.

[0023] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
