Embodiment 1

[0033] like figure 1 As shown, a method for judging water leakage of a washing machine in this embodiment specifically includes the following steps: detecting the real-time water inlet flow of the washing machine through the flow measuring device 2 arranged on the water inlet pipeline in the washing machine, and measuring the quality Q of the clothes by a weighing system ;Calculate the water inflow W in the washing machine through the real-time water inflow flow, and then combine the clothes quality Q and the structure analysis of the outer tub of the washing machine to calculate the calculated water level L1 in the outer tub of the washing machine; the calculated water level L1 in the outer tub of the washing machine and the actual water level L2 For comparison, if L1>L2, the control system 4 sends out a water leakage alarm signal.

[0034] like figure 2 As shown, in this embodiment, a washing machine is applied with the above washing machine water level detection method, a...

Embodiment 2

[0041] like figure 1 As shown, the method in this embodiment includes: a method for judging water leakage of a washing machine: detecting the water intake W through the flow measurement device 2 arranged on the water inlet pipeline; the flow measurement device 2 transmits the water intake W to the control system of the washing machine 4. The control system 4 of the washing machine converts the water intake W into the calculated water level L1 in the outer tub of the washing machine, and compares the calculated water level L1 with the actual water level L2. If L1>L2, the control system 4 sends out The alarm signal is displayed to the user through the output terminal, and the washing program is suspended.

[0042] like Figure 4As shown, in the present embodiment, the water inflow W is detected by the following method: the flow of water inflowing into the outer tub of the washing machine in real time is detected by the flow measuring device 2 arranged on the water inlet pipelin...

Embodiment 3

[0046] Such as image 3 As shown, in this embodiment, the revised water level L3 is a water level value correspondingly obtained by the control system according to the influence coefficient A and the weight Q of the clothes. The weight Q of the clothes is measured by the weighing system, and the measured weight Q of the clothes is transmitted to the control system. The said influence coefficient A is a revision value preset in the control system 4 . The influence coefficient A is divided into different coefficient values ​​An according to different clothing materials, and the control system 4 selects the corresponding coefficient value An according to the clothing materials washed by the user, so as to obtain the revised water level corresponding to the clothing material and clothing weight Q L3.

[0047] When the washing machine uses the above method to wash clothes, and the clothes washed by the washing machine are clothes made of various materials, the control system 4 re...

Abstract

The invention discloses a washer leakage judgment method and a washer thereof. The washer comprises a flow measuring device, a control system, a weighing system and a water level detection device, wherein the control system is used for realizing control, detection, display and alarm functions of the washer, the weighing system is used for detecting weight of clothes, and the water level detection device is used for detecting water level in an outer barrel. The method includes comparing a calculated water level L1 obtained by calculating water inflow and quantity of clothes to an actual water level obtained by detection, and judging the that the washer leaks if L1>L2. By the structure and the method, whether or not the washer leaks can be detected timely, and the washer can stop automatically and give an alarm after leakage is found. The washer is added with a leakage detection function, so that alarm for inflow abnormities is more timely and accurate, and great damage caused by leakage of the outer barrel is avoided.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a method for judging water leakage of a washing machine and the washing machine. Background technique [0002] With the improvement of people's living standards, people's requirements and expectations for washing machines are increasing day by day. People hope that their misoperation can be judged by the machine and reminded in time to avoid waste or even harm. At the same time, it is expected that the washing machine will be more intelligent and safer, so as to reduce human operations and achieve better washing results. [0003] Water level control technology has been widely used on washing machines now, and pressure sensors are generally used. Washing machines that use a pressure water level sensor to control the water level are generally implemented by the following method: detect the change in air pressure in the upper air chamber of the outer barrel after water is in, and s...
