Problems solved by technology

However, when the thyristor of the water inlet valve is abnormal, it will cause the computer board to fail to control the water inlet valve, which will cause the washing machine to be flooded or flooded, which not only causes a lot of waste of resources, but also affects the normal Laundry poses a safety hazard
On the other hand, the water overflow protection method adopted by the existing washing machine is to judge whether the water level of the washing machine exceeds the set value by using the accumulated times when the water level reaches the overflow water level; It is easy to reach the preset cumulative times, resulting in misjudgment of the computer board, causing frequent water stoppage or overflow of the washing machine, seriously affecting the washing quality and working efficiency of the washing machine

Embodiment 1

[0029] This embodiment provides a preferred washing machine overflow protection method to solve the problem that the existing washing machine is prone to water inflow and flooding when the water inlet valve SCR is abnormal, and at the same time solve the judgment of the existing water overflow protection method Inaccurate, easy to cause operational errors. The water overflow protection method of the washing machine is applicable to the washing machine water intake program, the washing program or the rinsing program. Specifically, such as figure 1 As shown, this embodiment takes the water overflow protection in the process of water inlet of the washing machine as an example for description.

[0030] The water overflow protection method of the washing machine in this embodiment includes the following steps:

[0031] Step 1: Plug in the washing machine and turn it on.

[0032] Step 2: Set the overflow protection water level of the washing machine according to the position of t...

Embodiment 2

[0045] This embodiment proposes a second preferred washing machine water overflow protection method, which is basically the same as the water overflow protection method described in Embodiment 1. The difference is that this embodiment takes the protection of the water level during the washing process of the washing machine as the For example, the setting of the washing water level is added.

[0046] The water overflow protection method of the washing machine in this embodiment includes the following steps:

[0047] Step 1: Plug in the washing machine and turn it on.

[0048] Step 2: Set the overflow protection water level of the washing machine according to the position of the overflow outlet on the outer tub of the washing machine, which is higher than the normal overflow water level of the washing machine; meanwhile, set the washing water inlet level of the washing machine according to the amount of clothes.

[0049] Step 3: Select the water inlet program of the washing mac...

Embodiment 3

[0058] This embodiment proposes a third preferred water overflow protection method for a washing machine, which is basically the same as the water overflow protection method described in Embodiment 2, the difference being that this embodiment adds the setting of a normal overflow water level.

[0059] Step 1: Plug in the washing machine and turn it on.

[0060] Step 2: Set the overflow protection water level of the washing machine according to the position of the overflow port on the outer tub of the washing machine. .

[0061] Step 3: Select the water inlet program of the washing machine to start water inlet, and at the same time reset the result of the overflow protection timer.

[0062] Step 4: Detect and judge whether the washing machine has reached the set washing water level, if yes, go to step 5, if not, go to step 3.

[0063] Step 5: The washing machine starts washing.

[0064] Step 6: Detect and judge whether the washing machine has reached the normal water overflo...

Abstract

The invention discloses a protection method for water overflowing of a washing machine, and relates to the technical field of washing machines. The method includes the following steps that A, the water-overflowing protection water level of the washing machine is set and higher than the normal water-overflowing water level of the washing machine; B, whether the washing machine reaches the water-overflowing protection water level is detected and judged; C, whether duration time after the water level reaches the water-overflowing protection water level exceeds first set time is judged, if yes, the washing machine starts alarming, and if not, the judgment process is continued; D, after alarming is kept for second set time, the washing machine is automatically powered off and shut down. The invention further discloses a full-automatic washing machine using the protection method for water overflowing. By setting the water-overflowing protection water level, the situation that water flows into the washing machine constantly or floods the washing machine when a water inlet valve of the washing machine is abnormal is prevented effectively; by the adoption of the judgment mode of constant timing, judgment is more accurate, the washing quality and working efficiency of the washing machine are improved, and resource waste and potential safety hazards are reduced.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a washing machine water overflow protection method and a fully automatic washing machine using the water overflow protection method. Background technique [0002] Existing washing machines are generally provided with a normal overflow water level. When the water intake reaches the normal overflow water level, the computer board of the washing machine controls the water inlet valve to stop the water intake, and the water exceeding the overflow port automatically flows out from the overflow port along the overflow pipe. However, when the thyristor of the water inlet valve is abnormal, it will cause the computer board to fail to control the water inlet valve, which will cause the washing machine to be flooded or flooded. This not only causes a lot of waste of resources, but also affects the normal Washing poses a safety hazard. On the other hand, the overflow protection me...
