The motor assembly 550 includes an agitator motor (not shown) that greatly generates a rotational force when power is applied, and a motor cover 552 that controls the flow of the agitator motor by shielding an upper surface of the agitator motor. do.

The agitator motor (not shown) generates rotational power by receiving power, and allows the agitator A to rotate. Therefore, the motor shaft 554 is formed in the left and right directions on the right side of the agitator motor.

The transmission belt 556 is surrounded by an outer circumferential surface of the motor shaft 554. The transmission belt 556 is simultaneously surrounded by the outer peripheral surface of the agitator (A) and the motor shaft 554 to generate a tensile force to transfer the rotational power generated by the agitator motor to the agitator (A).

Therefore, the transmission belt 556 is preferably molded of a material that is non-slip while retaining flexibility, such as rubber, so that slip does not occur when the motor shaft 554 rotates.

The motor cover 552 serves to block foreign material into the agitator motor and to prevent a safety accident. That is, when the upper cover 540 is peeled off, foreign substances from the outside are prevented from flowing into the agitator motor.

It is shaped to have a longitudinal cross section, and is paired with the same shape on the left and right sides when viewed from the front.

The restraining hook 576 is formed to have an elastic force, and serves to regulate the flow of the air guide member 580, the bottom surface of the upper portion formed to be round is the rear end of the upper surface of the air guide member 580 In contact with the air to regulate the upward flow of the air guide member 580.

In addition, the constraining hook 576 is formed integrally with the partition wall 570, and the partition wall 570 is formed integrally with the lower cover 530. That is, the restraining hook 576 is integrally formed with the lower cover 530. Accordingly, the restraining hook 576 is not damaged even when the air guide member 580 is bent backward by interfering with the rear end of the air guide member 580 when the air guide member 580 is attached to the cutout portion 572. It becomes possible to maintain.

On the front surface of the cutout 572, the guide protrusion 578 having a "b" shape when viewed from above is protruded. The guide protrusion 578 guides the insertion direction of the air guide member 580, and guides downward sliding by interfering with the left and right ends of the air guide member 580 so that the air guide member 580 is cut out. In line contact with (572).

Accordingly, when the air guide member 580 is guided by the guide protrusion 578 and is inserted downward, the rear end portion of the air guide member 580 interferes with the restraint hook 576 to restrain the hook 576. The elastic restoring force is generated.

In addition, when the air guide member 580 is further slidingly inserted downward so that the step portion 574 and the air guide member 580 are in line contact, at the same time, the restraint hook 576 is canceled to the original shape. The air guide member 580 is restrained from the cutout 572 by restoring the rear end of the upper surface of the air guide member 580 with the rounded front bottom of the restraining hook 576.

Further, when the air guide member 580 is further pushed downward, the air guide member 580 has a left side of the air guide member 580 and the left end of the air guide member 580 is restricted by the guide protrusion 578. Interference with the left side.

At this time, the restraint hook 576 is bent to the right side to generate an elastic restoring force, so that the air guide member 580 can slide downward.

When the downward sliding of the air guide member 580 is further progressed so that the bottom surface of the right side of the air guide member 580 contacts the upper surface of the stepped portion 574, the thickness and the stepped portion of the air guide member 580 are increased. Since the depression depth of 574 corresponds, the right end of the air guide member 580 terminates the interference with the restraining hook 576.

When the interference between the restraint hook 576 and the air guide member 580 is terminated, the restraint hook 576 is elastically supported by an elastic restoring force, such as in FIG. 7, more specifically, on the left side of the restraint hook 576. The bottom surface comes into contact with the upper right surface of the air guide member 580.
