AI Technical Summary

Problems solved by technology

However, as in the conventional example, when the pulley on the drive side is the motor shaft, since the diameter of the motor shaft is small, the circumferential speed becomes high, so the gap between the V-shaped groove 42 of the belt 38 and the V-groove 43 of the motor shaft 39 sliding (skidding)
Therefore, the rotation of the motor 20 cannot be accurately transmitted to the rotary drum 33
As a result, there is a problem that the performance in the washing process and the dehydration process is reduced.

Embodiment approach

[0022] figure 1 It is a longitudinal sectional view of the front-loading-type washing machine in embodiment of this invention.

[0023] Such as figure 1 As shown, the front-loading washing machine of this embodiment has a water tank 32 inside the washing machine main body 31, and a rotating drum 33 is pivotally supported inside the water tank 32. The outer peripheral wall of the rotary drum 33 is provided with a plurality of small holes 41 for draining water during dehydration operation, and the inner peripheral wall is provided with a plurality of protrusions 36 for stirring clothes. The clothes agitating protrusions 36 provided on the rotary drum 33 stir the clothes by low-speed forward rotation and reverse rotation (for example, 50rpm) in the washing process, and by high-speed one-way rotation (for example, 1000rpm) in the dehydration process. Centrifuge to separate water from laundry.

[0024] In addition, the rotary drum 33 is rotationally driven by the mechanism sho...

Abstract

A drum-type washing machine of the present invention includes a water tank (32) supported in a washing machine main body, a rotary drum (33) supported in the water tank (32), a motor (20) fixed to an outer bottom portion of the water tank (32), a driving pulley (2) provided on one end of a motor shaft (39) of the motor, a rotation shaft (35) having one end fixed to the rotary drum (33), a driven pulley (37) securely installed on the other rotation shaft (35) end, and a belt (42) transmitting rotation of the motor (28) to the driven pulley (37). A waterproof cover (1) covering around the driving pulley (2) is fixed to the motor (20). Thus, an unusual noise occurring due to a sliding friction between the driving pulley (2) and the belt (42) can be prevented from dispersing to the outside, and "slipping" can be prevented from occurring due to water attached to a sliding part between the driving pulley (2) and the belt (42).

Description

technical field [0001] The invention relates to a structure of a driving pulley and a belt of a motor driving a rotary drum of a drum type washing machine. Background technique [0002] Conventionally, as a structure for driving the rotating drum of a front-loading washing machine, for example, Japanese Patent Application Laid-Open No. 2009-78056 (hereinafter, referred to as "Patent Document 1") discloses a structure in which the drum is fixed to a water tank. The drive pulley on the motor shaft of the motor outside the bottom, or the drive pulley fixed to the motor shaft, transmits the rotation of the motor to the driven pulley directly connected to the rotary drum via a belt. [0003] Below, use Figure 4 The structure of the conventional front-loading-type washing machine described in Patent Document 1 will be described. Figure 4 It is a vertical sectional view of a conventional front-loading washing machine. [0004] Such as Figure 4 As shown, the conventional front-l...
