Washing machine having drying function

Abstract

A washing machine having a drying function is disclosed. The washing machine having a drying function may include a tub to receive wash water therein, a drum rotatably provided in the tub, to receive drying objects therein, a heater and a ventilation fan to generate hot air, a dry duct to guide the hot air into the drum, and cooling water supply means to supply cooling water to an outer circumferential surface of the drum to form a condensation surface, on which condensate is generated, on a surface of the drum.

Description

TECHNICAL FIELD[0001]Embodiments may relate to a washing machine having a drying function, more particularly to a washing machine having a drying function that has an improved condensation structure.BACKGROUND ART[0002]Generally, a washing machine is an electric appliance that is able to remove various contaminants attached to clothes, beddings and wearable items (hereinafter, laundry) by using emulsion action of detergent, friction of water currents generated by rotation of a pulsator or drum and shock applied to laundry. A full-automatic washing machine which is introduced recently performs a series of cycles including washing, rinsing and dry-spinning courses automatically, without a manual operation.[0003]In recent, demands for drum type washing machines have been increasing gradually, because drum type washing machines can reduce an overall height and generate no problems of wrinkles and tangle generated in laundry, compared with pulsator type washing machines.[0004]To put a st...

AI Technical Summary

Benefits of technology

This patent is about a washing machine that can increase its capacity without increasing its size. The machine has a supporting structure that can handle the larger tub. Additionally, the machine can effectively condense humid air without needing an extra duct.

Problems solved by technology

Such the drum type washing machine having the structure mentioned above generates vibration because of a rotational force of the drum generated when it is rotated and eccentricity of the laundry as an inevitable consequence.

As a result, the dimension of the drum type washing machine has to be limited by an installation environment.

It is limited to change an internal structure of such the drum type washing machine for the structure of the spring and damper provided between the tub and the cabinet to suspend and dampen the vibration, as mentioned above.

Also, it is limited to change the dimension of the washing machine, because the installation environment of the drum type washing machine is limited.

However, it is quite difficult in the structure of the conventional drum type washing machine to improve the dimension of the tub to improve the washing capacity, because of the limited conditions mentioned above.

However, such the conventional drum type drying machine has to include an auxiliary condensation duct.

Because of the condensation duct, an inner structure of the cabinet might be complex and the production cost might increase disadvantageously.
