Washing machine detergent remaining quantity detection and display method

A display method and detergent technology, which is applied to other washing machines, washing devices, buoy liquid level indicators, etc., can solve the problem of not being able to visually check the real-time remaining amount of detergent, not considering the viscosity of detergent, and being unable to do a good job Liquid addition preparation and other issues to achieve the effect of overcoming adverse effects, intuitive display, and easy replenishment

Problems solved by technology

First of all, using the probe to detect the liquid level can only remind the user to add detergent when the detergent is almost used up, and it is impossible to visually check the real-time remaining amount of detergent, so it is impossible to prepare for adding liquid, which is very inconvenient; secondly, there is no consideration Detergent viscosity problem, low detection accuracy

Embodiment Construction

[0019] figure 1 What is shown is a structural schematic diagram of an existing two conductive metal probes used as a warning for insufficient margin. As shown in the figure, at the bottom of the detergent box 2, two non-contact metal probes 30 are set. When the probes 30 are immersed in the detergent, the conduction is transmitted to the processor as a logical information with a margin. The washing machine can work normally; when the detergent is insufficient, the disconnection of the metal probe is sent to the processor 31 as a message of insufficient surplus, and an alarm for insufficient surplus is performed. This method is obviously simple and extensive, there are only "yes" or "no", and it is impossible to realize the real-time display of the remaining amount, and, once the metal probe is stuck by the viscous detergent, it will generate wrong signals and affect the washing effect (no washing action with detergent), wasting energy.

Abstract

The invention discloses a washing machine detergent remaining quantity detection and display method, relating to the automatic feed technology of washing machines. A controller reads the temperature sensor resistance value in a detergent box, calculates according to the resistance value to obtain a delay time, reads a liquid level resistance value of an analog quantity liquid level sensor after the delay, and controls the corresponding display of display units based on the liquid level resistance value. At least two display units are provided, and at least one of the display units offers low-liquid level alarm display. Through the invention, the real-time detergent liquid level state can be accurately obtained and sectionally displayed by multiple display units, the remaining quantity is displayed more visually and clearly, and the using effect of the whole automatic feed system is improved.

Description

technical field [0001] The invention relates to a washing machine, in particular to the detection, display and alarm technology of the remaining amount of detergent in the automatic feeding system of the washing machine. Background technique [0002] Many of the existing fully automatic washing machines have applied detergent automatic feeding devices. The general structure is: a detergent storage box is set in the washing machine, and detergent is pre-stored in the detergent storage box; a set of pumping system is set at the same time. When adding detergent, the detergent in the detergent storage box is put into the washing tub through the pump liquid system to participate in washing. Usually, the work of the pumping system is controlled by the main controller of the washing machine or the independent controller of the automatic feeding device to realize automatic operation. [0003] However, due to considerations such as aesthetics, the detergent storage boxes are arrange...
