Problems solved by technology
But in the weight of above-mentioned stator 6 just just be more than 1.5kg, and in the motor of large-capacity front-loading washing machine of about 600-2000RPM, because the weight of stator 6 and the vibration during high-speed rotation, and the rocking of rotor 5 and deformation, etc., the connection between the stator 6 and the barrel 2 is easily damaged
[0018] Moreover, in a drum washing machine using a BLDC motor and connecting the stator 6 to the rear wall of the tub 2, the diameter of the stator 6 is almost parallel to the ground, so the vibration generated during the operation of the washing machine will cause the stator 6 and the tub 2 to The damage of the connection between the more serious

Embodiment Construction
[0047] Below, will refer to Figure 5 to Figure 10 , the preferred embodiments of the present invention are described in detail.
[0048] Figure 5 It is a longitudinal sectional view schematically showing the structure of a direct-connection type drum washing machine according to the present invention.
[0049] As shown in the figure, the drum washing machine according to the embodiment of the present invention generally comprises the following parts: a tub 200 ; a stator 600 ; a rotor 5 ; and a supporting rib 810 .
[0050] Here, the above-mentioned tub 200 is disposed inside the casing 1 for storing washing water. The inside of the bucket is rotatably provided with a drum 3 . Here, the tub 200 has a rear wall for fixing the stator 600 .
[0051] The bucket 200 is made of plastic material, and the center of the rear wall is equipped with a metal bearing housing 7 , the bearing housing 7 is used to support the bearing and connect to the stator 600 .
[0052] Here, the abov...

The present invention relates to a coupling structure between a stator and a tub of a washing device, which can correctly determine the assembly position and minimize the risk of damage to the coupling position of the tub and the stator. The drum washing machine provided by the present invention includes: a plurality of drop parts and non-drop parts are radially formed on the rear wall surface of the tub, and a joint part is formed protruding from the central side of each drop part; a stator; a rotor, which is located on the stator The outer side of the stator and the stator together constitute a motor; the support ribs are provided along the entire part of the rear wall surface of the bucket where the inner wall surface of the partition rib of the stator is located, and are used to support the inner wall surface of the partition rib. In the drum washing machine of the present invention, due to the function of the support ribs, when assembling the stator, the coupling position of the stator can be more smoothly determined. In addition, even if vibration occurs during washing, breakage of the connection portion between the stator and the tub can be prevented.
Description
technical field [0001] The present invention relates to a front-loading washing machine, and more specifically, to a drive unit of a direct-connection front-loading washing machine. Background technique [0002] Generally speaking, according to different driving methods, front-loading washing machines can be divided into the following types: the indirect connection type that indirectly transmits the driving force of the motor to the drum through the belt wound around the motor pulley and the drum pulley; the rotor of the BLDC motor A direct connection type that directly connects to the drum and directly transmits the driving force of the motor to the drum. [0003] In the method in which the driving force of the motor is not directly transmitted to the drum, but is transmitted through a belt wound around the motor pulley and the drum pulley, energy loss occurs during the driving force transmission process, and a lot of noise is generated during the power transmission process...
