Description

Structure for improving washing ratio of drum washing machine

Technical Field

The utility model relates to the technical field of electric appliances. And more particularly to a washing machine, including domestic and industrial washing machines.

Background

Currently, a drum type washing machine, a pulsator type washing machine and a stirring type washing machine are commonly used in the market of the washing machine according to a washing mode; the method is divided into the following fields: household and industrial applications; the method is divided into the following steps according to the design mode of the washing barrel: the drum type washing machine comprises a vertical drum (barrel) and a horizontal drum (barrel), wherein the pulsator washing machine and the agitator washing machine are the vertical drum (barrel), the drum washing machine is the horizontal drum (barrel), and the drum washing machine is divided into: a horizontal transverse cylinder and an inclined transverse cylinder;

the basic configuration of the drum washing machine (including a horizontal drum and an inclined drum) includes: the washing machine comprises a shell, a water containing barrel, an elution barrel, a damping device, a driving device, an electric control device, a washing powder box, a water supply device, a drainage device, lifting ribs (or lifting ribs), a balancing weight, a clothes throwing opening and a sealing door; the preparation method comprises the following steps: heating device, illumination, drying device, disinfection, clean elution section of thick bamboo etc. functional configuration. For example, the domestic drum washing machine is provided with national standard GB4288-2018, the primary energy consumption is realized, the carbon black cleaning ratio is more than 1.03, the washing time is generally more than 3 hours, most of the industrial washing machines are drum washing machines, the structure is basically the same as that of the domestic drum washing machines, the drum wall of an inner drum (also called an elution drum) of the washing machine is provided with a plurality of holes, 3 raised lifting ribs (also 2, 4, 5 or more) are generally arranged in the drum wall, the raised drum wall is more than 5cm in height, and the raised bags or ribs formed by punching the drum wall of the inner drum outside the lifting ribs are commonly characterized in that the raised drum wall is more than 3mm in height.

Technical problems: the existing drum washing machine has long washing time and low washing efficiency for clothes.

Disclosure of Invention

The application provides a structure for improving the washing ratio of a drum washing machine, which can improve the washing ratio of the drum washing machine under the condition of the same energy consumption.

A plurality of ribs or bags with inward protrusions are uniformly distributed on the wall of the elution barrel, the height of the protrusions is generally in the range of 0.5 cm to 1/10 of the diameter of the barrel, and the higher the height of the ribs or bags is, the higher the washing efficiency is, but the higher the ribs or bags are, the less likely the ribs or bags are, because the ribs or bags tend to reduce the volume of the elution barrel.

The protruding ribs are fully distributed on the inner wall of the eluting barrel.

The raised ribs or bags are staggered with holes on the wall of the elution barrel, so that water can conveniently enter and exit.

The spacing of the ribs or pockets is generally 2-3 times the height thereof, and exceeding this range reduces the effect of improving the cleaning ratio.

The cross section of the convex rib or the bag is small in inner and large in outer, namely, one end far away from the eluting barrel wall is small, and one end close to the eluting barrel wall is large.

The raised ribs or pockets may be non-uniform in height and may be staggered or alternating in arrangement.

The raised ribs may be used in combination with the raised pack.

The included angle between the raised ribs and the bottom surface of the elution barrel is 45-90 degrees, which is beneficial to improving the cleaning ratio and reducing the uniform dehydration time.

When the heights of the raised ribs or bags are smaller than 3 cm, the optimal washing effect can be achieved by controlling the rotating speed change of the eluting barrel.

When the water level in the eluting barrel is higher than or equal to 70% of the height of the washings, the rotating speed of the eluting barrel is in the range of 20-60 revolutions, so that the high washing ratio can be realized in a short time like a pulsator, and the abrasion is increased.
