Description

Fan assembly, blower device, double duct clothes dryer

technical field

The utility model relates to the field of household electrical appliances, in particular to a fan assembly, a blower device, and a double-air duct clothes dryer.

Background technique

In the prior art, after continuous improvement and optimization, clothes dryers have functions such as lifting and drying. In general, the main machine of a clothes dryer has an air outlet and a corresponding air source for supplying air to the air outlet. The airflow generated by the air source passes through the heating module and is blown out from the air outlet. Thereby, the clothes hanging on the clothes rail are dried.

The air outlet of the clothes dryer is generally arranged in the middle of the main machine, and a swing structure is arranged at the air outlet. In order to improve the drying efficiency, the traditional product idea is to increase the air volume. Two centrifugal fans are installed to increase the air volume blown out of the air outlet. The two fans also need to be equipped with two heating modules. While the air volume increases, a high heating temperature is required. Therefore, the power of both is relatively high, and the internal structure that needs to support high power is relatively complicated, and the failure rate is high. Moreover, the materials of the clothes are different, so it is not appropriate to simply increase the temperature and air volume. For the preparation of modern fabrics from functional fibers and yarns, they can only be dried at low temperature, and high power will cause waste in configuration.

Another object of the present utility model is to provide a double-air duct clothes dryer, which at least includes a host, and the host has at least:

the above-mentioned fan assembly;

The heating module is arranged on the air outlet path of the fan assembly.

In summary, the utility model has the following beneficial effects:

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

The first preferred embodiment:

A fan assembly, as shown in Figures 1-3, the fan assembly includes an air duct 100, the air duct 100 has a spiral air duct 102, and the center of the spiral air duct 102 has an air source 200, and the air source 200 has at least an adaptive To the impeller 201 at the center of the volute air channel 102 , the volute air channel 102 has a volute 104 , and the rotation of the impeller 201 generates airflow blown out from the volute 104 .

The air duct 100 also includes at least two linear air ducts 101 , and the linear air ducts 101 communicate with the spiral mouth 104 of the spiral air duct 102 . According to the schematic angle in the figure, the spiral air duct 102 and the linear air duct 101 are located on the same plane, and the axis of the impeller 201 is perpendicular to the plane where the spiral air duct 102 and the linear air duct 101 are located. The airflow generated by the impeller 201 is blown into two different linear air ducts 101 .

There are air outlets 300 on the linear air duct 101 , and the air outlets 300 are arranged linearly or arranged linearly on the linear air duct 101 . That is to say, the air outlets 300 can be strip-shaped air outlets 300 , one section or multiple sections are arranged on the linear air duct 101 , and other shapes can also be arranged in a straight line on the linear air duct 101 .

The air duct 100 also includes an air guide duct 103 connecting each linear air duct 101 and the spiral air duct 102, the air guide duct 103 is integrally arranged with the linear air duct 101 and the spiral air duct 102, and the air guide duct The size of the inlet of 103 is evenly adapted to the size of the volute 104 . The airflow blown out by the worm mouth 104 is evenly divided into each linear air duct 101 . The number of linear air ducts 101 is set according to user needs.

When the impeller 201 in the spiral air duct 102 rotates, the initial position has a large air volume, and the air volume flows from the initial position to the rear side, that is, it needs to flow to the linear air duct 101 through the air guide duct 103 . In order to fully utilize the air volume without affecting the blocking blowing speed, the volume of the air guide duct 103 is larger than that of the linear air duct 101 , which is more conducive to efficiently extracting the airflow.

The fan assembly of this embodiment can be applied to a blower device, such as a heater, a bathroom heater, or an air conditioner built-in unit. The heating effect can be realized by arranging a heating module on the air outlet path of the fan assembly.
