Supporting structure of tub for a laundry machine

A laundry machine, comprising:

• a cabinet having a base;
• a tub fixedly mounted at a front of the cabinet to hold water therein, the tub having horizontally flat portions at lower front and rear central portions thereof that extend downward from an outer circumference of the tub;
• each having a fitting protrusion;
• a drum rotatably placed in the tub;
• a drive assembly including a shaft that extends through the tub and is connected to a rear wall of the drum, a bearing housing that rotatably supports the shaft, and a motor to rotate the shaft;
• a damper bracket attached to the bearing housing;
• a suspension attached to the damper bracket and that flexibly supports the drive assembly separately from the supporting of the tub;
• a flexible material to prevent the water inside the tub from leaking toward the drive assembly and allow the drive assembly to move relatively to the tub;
• and
• a support that supports the tub at a circumferential surface of the tub at the lower front and rear central portions thereof, separately from the supporting of the drive assembly and separate from the suspension, wherein the support includes:
• a front supporter separate from the cabinet and installed at a front side of the base, wherein the front supporter supports a front side of the tub and connects the lower front central portion of the tub directly to the base to rigidly support the tub with respect to the base and prevent a vertical movement of the tub with respect to the base;
• and
• a rear supporter separate from the cabinet and installed at a rear side of the base, wherein the rear supporter supports a rear side of the tub and connects the lower rear central portion of the tub directly to the base to rigidly support the tub with respect to the base and prevent the vertical movement of the tub with respect to the base, wherein the tub is installed in the cabinet in a tilted state, wherein each of the flat portions of the tub is formed with a slant such that a front portion is higher than a rear portion thereof, wherein the fitting protrusions of the lower front and rear central portions mate with corresponding support grooves of the front supporter and the rear supporter, the corresponding support grooves being slantingly formed to be parallel to a tilting direction of the tub when the tub is installed in the cabinet in the tilted state, a distance between the base and the lower front and rear central portions of the tub is the same.
