Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a dryer motor with a built-in fan. Background Technology

[0002] A clothes dryer is a household appliance that uses electric heating to instantly evaporate the moisture from washed clothes. It is especially useful in northern winters and the humid, rainy seasons in the south where clothes are difficult to dry. Currently, household clothes dryers mainly consist of a stand, a main unit, and an outer casing. They are characterized by their moderate price, ease of use, and low failure rate, making them suitable for ordinary families, students, and mobile groups.

[0003] Clothes dryers are used in high-temperature environments and are typically used for long periods of time. Ordinary motors have simple structures and limited heat dissipation performance, which cannot effectively cope with prolonged high-temperature environments, leading to malfunctions due to insufficient heat dissipation. Utility Model Content

[0004] The purpose of this invention is to provide a dryer motor with a built-in fan. This invention has the advantage of effectively dissipating heat and reducing the failure rate.

[0005] The technical solution of this utility model is as follows: A dryer motor with a built-in fan includes a body and a fan built into the body; the body includes a stator core, a rear cover and a tension cover distributed on both sides of the stator core; a main rotating shaft is inserted inside the stator core; a rotor is sleeved on the main rotating shaft; the fan is sleeved on the main rotating shaft and located between the rotor and the tension cover; heat dissipation holes are opened on the tension cover; multiple fan blades are evenly distributed at one end of the rotor near the rear cover.

[0006] In the aforementioned dryer motor with a built-in fan, the main shaft is provided with two bearings corresponding to the rotor and the fan, respectively. Each bearing is provided with a retaining ring, and the bearing and the retaining ring serve to prevent loosening.

[0007] In the aforementioned dryer motor with a built-in fan, a coil is provided inside the stator core; and a shock-absorbing ring is provided outside the stretch cover.

[0008] In the aforementioned dryer motor with a built-in fan, a linkage mechanism is provided outside the back cover; the linkage mechanism includes a capacitor on the back cover, a secondary rotating shaft passing through the back cover, an aluminum pulley sleeved on the secondary rotating shaft, a belt pulley corresponding to the back cover and sleeved on the main rotating shaft, and a belt connecting the belt pulley and the aluminum pulley.

[0009] Compared with the existing technology, this utility model has a built-in fan inside the motor, which dissipates heat while the motor is working. This results in better heat dissipation than traditional motors, effectively improving performance and making the corresponding products safer and more reliable.

[0010] This application, by using a built-in fan, can effectively reduce costs at the same power level, making the product more competitive in the market.

[0011] By installing fan blades under the rotor, the heat dissipation effect is further improved.

[0012] Therefore, this utility model has the advantage of effectively dissipating heat and reducing the failure rate. Attached Figure Description
