Embodiment Construction

[0043] Hereinafter, modes for implementing the present invention (hereinafter referred to as "embodiments") will be described in detail with reference to the drawings as appropriate. Hereinafter, a washing machine capable of washing, rinsing, dehydrating, and drying (so-called vertical washer-drying machine) is taken as an example for description, but it can also be applied to a vertical washing machine capable of washing, rinsing, and dehydrating (so-called full washing machine). automatic washing machine).

[0044] figure 1 It is an external perspective view showing the washing machine according to the embodiment of the present invention. figure 1 Indicates the state where the outer cover 3 is opened.

[0045] Such as figure 1 As shown, the washing machine 100 includes a casing 1 whose outer outline is a combination of a steel plate and a resin molded product. On the upper part of the box body 1, a top cover 2 made of resin is provided. The top cover 2 is provided with ...

Abstract

The present invention provides a washing machine with improved cleaning performance. The washing machine includes an outer tank; an inner tank rotatably supported in the outer tank; and a circulation pump that draws the washing water accumulated at the bottom of the outer tank and returns the washing water to the inner tank to circulate the washing water, wherein the circulation pump is driven so that the circulation flow rate is 30 L / min or more.

Description

technical field [0001] The present invention relates to a washing machine (also referred to as a "washing machine") for washing by circulating washing water. Background technique [0002] The washing machine can reduce the physical force (mechanical force) acting on the laundry by effectively utilizing the chemical cleaning power of the detergent in the washing process, and obtain high cleaning power. In addition, in recent years, in order to prevent global warming, energy saving of household electrical appliances is advancing. In a washing machine, water saving is effective, but if the amount of water is reduced, the washing water cannot sufficiently penetrate the laundry, and detergency and rinsing deteriorate. Therefore, there has been proposed a washing machine equipped with a washing water circulation mechanism that pumps the washing water accumulated at the bottom of the washing tub to the upper part of the washing tub with a circulation pump, and spreads (disperses) ...
