Embodiments of the present invention relate to a washing machine, and more particularly, to a washing machine and a manufacturing method thereof.

Generally, a washing machine is a device for washing clothes by using friction between laundry and laundry such as contaminated clothes or bedding.

Specifically, the washing water forms a water flow in the washing water by the rotation of the pulsator or the agitator so that the washing water and the washing water effectively rub.

These pulsators are installed inside the inner tub. Further, the upper portion of the inner tub is opened for receiving the laundry, and the lower portion of the inner tub is assembled with a tub-u formed to have a smaller diameter toward the lower side of the inner tub.

However, there is a problem in the design of the pulsator diameter due to the assembly of the tub oil. Specifically, since the shape of the pulsator must be selected and installed considering the turbine oil that is narrower than the diameter of the inner tub, the installation space of the pulsator is limited.

Embodiments of the present invention provide a washing machine and a method of manufacturing the same that can improve the freedom of installation space of a pulsator.

The tub flange may include a radial extension having a plurality of protrusions formed along the circumferential direction of the inner tub to support the connection between the driving unit and the inner tub.

The radial extension may be formed by being bent to be inserted into the inner tub and may be coupled with the inner circumferential surface of the inner tub.

Alternatively, the radial extension may be formed to be bent to support the inner tub and be coupled with the outer circumferential surface of the inner tub.

Alternatively, the radial extension may extend to an outer circumferential surface of the inner tub and be coupled to one surface of the inner tub.

According to another aspect of the present invention, there is provided a method of manufacturing a washing machine, the method comprising: an inner tub forming step of forming a cylindrical inner tub having an open top and bottom; and forming a tubular flange including a plurality of radially extending radially extending protrusions And a fastening step of tightening the tubular flange forming step and the radial supporting part of the tubular flange to engage with each other so that the opened one surface of the inner tub is coupled.

According to the embodiments of the present invention, the washing machine and the manufacturing method thereof can effectively improve the freedom of installation space of the pulsator.

That is, when the radial extension portion 321 is engaged with the outer circumferential surface of the inner tub 310, compared to the case where the radial extension portion 321 is engaged with the inner circumferential surface of the inner tub 310, You can have degrees of freedom.

Hereinafter, the tub flange 320 of the washing machine 103 according to the third embodiment of the present invention will be described with reference to FIG. 6 and FIG. 3 described above. The description of the same configuration as the first embodiment of the present invention described above will be omitted.

The radial extension 321 of the tub flange 320 according to the third embodiment of the present invention may be formed by bending.

One end of the radial extension portion 321 may be bent to be inserted into the inner tub 310 and coupled with the inner circumferential surface of the inner tub 310.

That is, one end of the radial extension portion 321 is bent to be inserted into the inner tub 310 and inserted into the inner circumference of the inner tub 310, and the bent radial extension portion 321 is inserted into the inner circumferential surface of the inner tub 310 Can be combined.

In this case, the contact area between the inner peripheral surface of the inner tub 310 and the radial extension portion 321 is improved and can be effectively combined.

According to such a configuration, the washing machines 101, 102, and 103 according to the embodiments of the present invention can improve the degree of freedom in the installation space of the pulsator 200.

That is, the tub flange 320 can support one open side of the inner tub 310, thereby improving the degree of freedom in selecting the diameter of the pulsator 200 installed in the inner tub 310.

Hereinafter, a method of manufacturing the above-described washing machines 101, 102, and 103 will be described.

The manufacturing method of the washing machine 101, 102, 103 includes a tub forming step, a tub flanging forming step, and a fastening step.

The tuft forming step forms a cylindrical inner tub having upper and lower openings. Specifically, the inner tub includes a metal material. Therefore, the plate-like material can be manufactured by joining both ends to each other to form a cylindrical shape or using a tubular shape.

The tub flange may include a radial extension having a plurality of radial projections formed therein.

In the fastening step, the inner flange formed in the inner tub forming step and the tub flange formed in the tub flange forming step are fastened.
