Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The principles and construction of the present invention will be described in detail below with reference to the drawings and examples.
As shown in fig. 1 and 2, the present invention provides a method for determining water inflow of a washing machine, comprising the steps of:
the washing machine starts (the user presses the start signal that washing machine power key sent), then operates the overtime judgement procedure of intaking, this overtime judgement procedure of intaking specifically is:
opening a water inlet valve and a water discharge valve of the washing machine to form a water flow channel between the water inlet valve and the water discharge valve, wherein the water flow channel does not pass through the inner barrel of the washing machine;
and judging whether water is fed overtime or not according to a water flow signal of a water level monitoring device arranged on a pipeline between the water inlet valve and the water discharge valve. By the scheme of the invention, when a user presses a power switch key of the washing machine, the water inlet overtime judgment program is automatically entered, the water inlet valve and the water discharge valve are opened, when a water inlet filter screen is blocked, the water inlet valve is damaged, the water inlet water pressure is too low, and a water tap is forgotten to be boiled, no water flows into the water level monitoring device in the detection area, the controller of the washing machine can timely judge whether water passes through or not through the value difference returned by the water level monitoring device, and when no water passes through, the controller timely records the water inlet overtime fault. When the user selects the washing parameters and presses the start key to start the washing machine, the controller can inform the user of the water inlet abnormity in the early warning mode of water inlet overtime determined before. Therefore, the user can find the water inlet overtime abnormity in time and further check the corresponding fault.
The specific judgment of whether water inlet overtime exists or not according to the signal of the water level detection device is as follows: when the water level detection device does not detect a water flow signal within the preset time after the water inlet overtime program operates, the water inlet overtime is judged, after the water inlet overtime is judged, an alarm is given to the user when the user presses a start key to start washing, the alarm can be a buzzing alarm or a light alarm, and a fault code is displayed on an operation interface of the washing machine.
When the water level detection device detects a water flow signal within a preset time after the water inlet overtime program operates, the water inlet overtime judgment program is judged to be normal, and the water inlet overtime judgment program is directly quitted and the next operation program is entered, namely the washing program set by the user is operated.
The preset time may be set as desired, and may be set to a value between 1s and 9s, for example, 2 s.
The invention also provides the washing machine, and the water inlet judgment method is used for judging whether the water inlet of the washing machine is overtime or not and reminding a user in time.
Now, the pipeline structure of the washing machine will be described in detail, and other structures are not described in detail. As shown in fig. 3, the water supply device mainly comprises a main water inlet pipe 1, an inner cylinder pipe 3 and a branch pipe 2, wherein an inlet of the main water inlet pipe 1 is connected with a faucet 41, a water inlet valve 42 is arranged on the main water inlet pipe 1, water can flow through the main water inlet pipe 1 after the water inlet valve 42 is opened, and a tee joint is arranged at an outlet of the main water inlet pipe 1, so that the main water inlet pipe can be simultaneously connected with the two pipes. The two pipelines are: an inner cylinder pipeline 3 connecting the outlet of the water inlet main pipe and the inner cylinder enables water to directly flow to the inner cylinder. A branch pipeline 2 connecting the outlet of the water inlet main pipe 1 and the water outlet of the washing machine, and a drain valve 43 is arranged on the branch pipeline 2. When the drain valve 43 is opened to communicate with the branch pipe 2, water flows out through the branch pipe 2 first due to the water pressure, and does not flow directly to the inner cylinder. A water level detection device 5 for detecting water flow is arranged between the outlet of the water inlet main pipe 1 and the water inlet valve 42, so that after the water inlet valve and the drain valves on the branch pipelines are opened, the water flow can be detected through the water level detection device, and whether water enters or not is judged.
The water level detection device is a probe type water level sensor, the resistance value between the double probes of the probe type water level sensor is large, when the controller detects that the resistance value between the double probes is large, the controller considers that no water enters the water level detection area at the moment, and therefore the situation that a filter screen is blocked, a water inlet valve is damaged, the water pressure of inlet water is too low, and the water inlet overtime is caused by forgetting to boil a water tap can be judged.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
