Embodiment Construction

[0020] The working process is briefly described below:

[0021] Before washing, the washing machine first detects the amount of clothes, and then the washing water flows through the water inlet pipe to the water tank provided above the transparent observation window 8 of the door 14 and is introduced into the drum 1. The detection of the water level is carried out by the water level sensor 13. Low-speed rotation, the control system detects and compares the water level multiple times during each rotation of the drum 1, and the highest water level is the current water level of the washing machine. Water level detection also can not establish water level sensor 13, can adopt the method for clothes amount detection to detect water intake earlier, then correct according to the water absorption rate of different clothes and get water level. During the water inlet process, the electric heating belt 9 heats the outer wall of the drum until the temperature measured by the temperature s...

Abstract

The invention relates to an improvement of a single drum washing machine with dehydration holes capable of automatically opening and closing. In the popular telescope-feed drum washing machine at present, washing water exists between the inner and outer drums; and thus, the telescope-feed drum washing machine wastes water and electric energy, and dirt accumulated in the interlayer between the inner and outer drums can pollute clothes. The existing single drum washing machine with dehydration holes capable of automatically opening and closing is environment-friendly, but has the defects of poor dehydration effect and high tendency to water leakage at the drum. The drum 1 of the invention is in a drum shape, the dehydration holes 3 are distributed on the bulges of the drum 1 and respectively provided with a shutter 2b (elastic ring). During washing, the shutters 2 close the dehydration holes 3 by utilizing the elastic force; and during dehydration, the diameter of the shutters 2 rises under the centrifugal action, and the inner side surface of each shutter and the outer wall of the drum 1 generate a clearance, thereby opening the dehydration hole 3. The invention has the advantages of simple structure, favorable dehydration effect and no secondary pollution for clothes.

Description

Technical field [0001] The invention relates to a single-tub drum washing machine, in particular to an improvement of the drum of a single-tub drum washing machine. Background technique [0002] A single-tub drum washing machine generally includes an outer tub for collecting washing water and a drum integrated with water storage and dehydration functions rotatably installed in the outer tub. Because there is no washing water between the outer tub and the drum, it not only saves energy and water, but more importantly, there is no interlayer pollution between the outer tub and the drum. The Chinese patent application number 200610087784.1 discloses a drum washing machine, which includes an outer tub (shell) and a cylindrical drum rotatably installed in the outer tub and an opening and closing device. The embodiment of the opening and closing device is as follows: figure 1 As shown in middle 2a, it consists of an elastic part (elastic belt) and an opening and closing part (sma...
