Embodiment Construction

[0027] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0028] The invention proposes a new type of water inlet control method for drum washing machines. The water consumption required for this washing is calculated through the load weighing function and the detection of the load water absorption rate, and then sufficient water is provided by one-time replenishment to improve multiple times under heavy load conditions. The problem of frequent switching of the heating tube caused by replenishment of water.

Abstract

The invention discloses a water inlet control method of a drum washing machine. The water inlet control method comprises the following steps: when clothes are detected to be put into an inner drum, obtaining the weight of the dry clothes; controlling an inlet valve to be opened to feed water to a main washing water level, and calculating the water absorption rate of the clothes; obtaining the water supplementing water yield according to the water absorption rate and the weight of the dry clothes; controlling the inlet valve to supplement water according to the supplementing water yield; and carrying out main washing and controlling a heating tube of the drum washing machine to be opened after water is supplemented. The water inlet control method disclosed by the invention can avoid influences on heating performances and reliability of the heating tube because the heating tube is frequently closed and opened for repeatedly supplementing water. The invention further discloses the drum washing machine.

Description

technical field [0001] The invention belongs to the technical field of electric appliance manufacturing, and in particular relates to a water inlet control method of a drum washing machine and the drum washing machine. Background technique [0002] Drum washing machines are popular among users for their low water consumption, low entanglement, and low wear rate. In order to meet the cleaning ratio requirements, the drum washing machine needs to be heated by the heating tube to increase the water temperature in the bucket to improve the cleaning efficiency. However, the prerequisite for the heating tube to work is that the water level in the washing machine tub must be higher than the set main wash water level. If the water level drops, the controller will immediately cut off the heating tube. . [0003] At present, the water intake method of the drum washing machine is as follows: the software sets the water level of the main wash, opens the water valve to enter the water ...
