Laundry treating machine

Abstract

The laundry treating machine includes a silencer for covering the upper space over the drain hole, whereby the upper space over the drain hole is always filled with washing water and the generation of a vortex is prevented. Thus, abnormal noise during drainage is prevented, thereby contributing to a quiet operation of the washing machine and improving consumer trust.

Description

BACKGROUND OF THE INVENTION1. Field of the InventionThe present invention relates to a laundry treating machine, and more particularly, to a laundry treating machine which can reduce noise generated during drainage.2. Discussion of the Related ArtGenerally, laundry treating machines are classified into washing machines removing dirt or dust from clothes, bedclothes, etc (hereinafter, referred to as ‘laundry’) by using water and detergent and using mechanical operations, dryers drying wet laundry by using a dry, hot wind generated by a heater and using mechanical operations, and combination washer dryers performing both a washing function and a drying function.Also, the washing machines may be classified into a top loading type washing machine having a laundry inlet / outlet hole formed in the top surface of a cabinet and through which laundry comes in and out and performing washing using a spinning stream of water generated by the rotation of an inner tub and a drum washing machine ha...

AI Technical Summary

Benefits of technology

The laundry treating machine according to the present invention includes a silencer covering the vertical top of the drain hole, whereby the top of the drain hole is always filled with washing water and the generation of a vortex is prevented. Thus, abnormal noise during drainage is prevented, thereby contributing to a quiet operation of the washing machine and improving consumer trust.

Moreover, as the silencer includes a drain hole cap, the laundry washing machine according to the present invention allows washing water to be introduced in a lateral direction while covering the vertical top of the drain hole. Thus, the drainage of the washing water can be properly carried out, and abnormal noise during drainage can be prevented.

Furthermore, the laundry treating machine according to the present invention has the advantage of simple structure and easy installation since the silencer includes a plate shaped drain hole cover.

Furthermore, as the laundry treating machine according to the present invention includes a heater cover which is disposed in the heater mounting groove so as to cover the top of the heater and covers the vertical top of the drain hole, washing water is drained after being filled between the heater cover and the drain hole, thereby preventing the generation of a vortex and abnormal noise.

In addition, the laundry treating machine according to the present invention includes a heater cover hole which is formed in the heater cover for emitting heat generated from the heater and assisting in drainage and is disposed at a position not overlapping with the drain hole. Therefore, it is advantageous in that both heat emission and drainage are properly carried out.

Additionally, the laundry treating machine according to the present invention includes a heater cover which is disposed for covering the heater mounting groove. Therefore, it is advantageous in that a washing water stream can be properly formed by eliminating a stepped part of the bottom surface of the outer tub.

Problems solved by technology

However, the conventional top loading type washing machine creates a vortex because of a temporary decrease in the water pressure of the drain port caused by a difference between an amount of drainage and an amount of pumping in an early stage of drainage.

If a vortex is generated, air enters through an upper side of the drain port to form an air layer through which no water flows, and abnormal noise is generated in an early stage of drainage due to the air layer.

Noise generated during drainage makes users feel uncomfortable.

Moreover, the air layer causes lowering of pumping performance.
