Detailed Description

In order to make the technical problems solved, the technical solutions adopted and the technical effects achieved by the present invention clearer, the technical solutions of the present invention are further described below by way of specific embodiments with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the elements associated with the present invention are shown in the drawings.

Referring to fig. 1 to 4, an embodiment of the present invention provides a method for controlling washing in a dishwasher, including a main washing stage and a rinsing stage, and before the main washing stage, a pre-washing stage in which items to be washed are washed with a first water flow intensity is further included. Can wash away the great filth on the article of waiting to wash, prevent that great filth from causing the influence to follow-up turbidity detection, improve washing efficiency and clean effect.

Because the main purpose of the pre-washing stage is to wash the larger dirt on the articles to be washed, a larger water flow speed is required to achieve a larger washing force and achieve quick washing. Here, the first water flow intensity is not limited, and may be set according to actual needs.

Referring to fig. 2, the pre-flush phase includes: and (3) feeding water to a first set amount, and starting heating until the temperature of the washing water reaches the first set temperature and the water feeding reaches a second set amount. The heating is carried out in the pre-washing stage, so that the dirt on the object to be washed can be washed away better, and the cleaning effect is improved. The temperature of the washing water reaches the first set temperature, which is convenient for washing the dirty objects, and the first set temperature is not limited. After the washing program begins, the water inlet pipeline is opened and water is fed, the first set amount can be that water just overflows the articles to be washed, the first set amount is 1/3-1/2 of the second set amount, and the first set amount and the second set amount are not limited.

In the pre-washing stage, temperature detection and water inflow detection are required, water is fed while heating, and the detected current temperature is compared with a first set temperature until the temperature of the washing water reaches the first set temperature; meanwhile, the water inflow is recorded in real time until the water inflow reaches a second set amount. Because the temperature detection and the water inflow detection are performed at intervals, for example, one temperature detection is performed at an interval of 10s, if the first set temperature is a point value, the temperature detected at one time is lower than the first set temperature, and the temperature detected at the next time may be higher than the first set temperature, therefore, the first set temperature here may be a range, and when the current temperature is within the range, the first set temperature is considered to be reached.

While heating, the circulating water pump is operated at a first power; and after the temperature of the washing water reaches the first set temperature and the water inlet reaches the second set amount, the circulating water pump continues to operate for the first set time to drain water. And timing the first set time after the temperature of the washing water reaches the first set temperature and the inlet water reaches the second set amount. Perhaps when the temperature of the washing water is not yet the first set temperature when the inlet water reaches the second set amount, stopping the inlet water and continuing to heat; it is possible that the temperature of the washing water reaches the first set temperature, the inflow water does not reach the second set amount, and the inflow water is continued, and thus the temperature of the washing water is changed, so that the heating is continued.

The operation of circulating water pump for rivers produce the disturbance, can evenly treat the surface of washing article and wash, and can make the filth get into the aquatic, discharge when being convenient for the drainage. For flushing purposes, the first power of the circulating water pump can be a higher power, for example 80% of the nominal power, without limitation. After the temperature of the washing water reaches the first set temperature, the heating may be stopped.

Referring to fig. 3, after the pre-flush stage completes the draining, the larger contaminants are drained, followed by the main wash stage. And heating and real-time turbidity detection are carried out in the main washing stage, and a subsequent washing mode is adjusted according to the turbidity value. And the subsequent washing mode is a main washing stage and a rinsing stage after turbidity detection, and parameters of the subsequent main washing stage and the rinsing stage are adjusted according to the turbidity value.

And adjusting the heating temperature, the water inflow and the washing time of the main washing stage according to the turbidity value, and continuing washing according to the adjusted parameters. When the turbidity value is large, it is necessary to increase the heating temperature, increase the water inflow, and/or lengthen the washing time. Here, a range of turbidity values or a standard turbidity value may be set, and when the detected turbidity value is higher than the standard turbidity value, the turbidity is considered to be large.

The main washing stage comprises: and feeding water to a first water inflow, starting heating, simultaneously putting detergent and controlling the circulating water pump to operate at a second power until the temperature of the washing water reaches a second set temperature and the water is fed to a second water inflow. The temperature of the washing water is heated to a second set temperature, which maximizes the activity of the detergent. The operation of circulating water pump for rivers produce the disturbance, can evenly treat the surface of washing article and wash, and can make the filth get into the aquatic, discharge when being convenient for the drainage. For the purpose of uniform flushing, the second power of the circulating water pump may be a smaller power, for example 60% of the rated power, without limitation. After the water is fed to the first water inflow, the water is fed while heating is started, and the time is saved. The water inflow reaches the second water inflow, and the water level exceeds the object to be washed, so that the object to be washed is completely submerged, and a better washing effect is convenient to achieve.

And (4) heating to a second set temperature, washing for several minutes after the inlet water reaches a second inlet water amount, and detecting the turbidity value of the washing water. The turbidity detection is a plurality of real-time detections, and the turbidity of water can be more accurately judged by the plurality of detections; real-time detection can carry out the contrast judgement according to the turbidity value more effectively, later make more accurate control regulation to washing heating temperature, washing time, inflow.

Here, a range of turbidity values may be set, and a temperature required to be heated, a time required to be washed, and an amount of water required to be fed may be determined according to the range of turbidity values detected in the main washing stage. For example, if the turbidity value is within the first set range, it needs to be heated to a third set temperature, where the third set temperature is higher than the second set temperature; if the turbidity value is in a second set range, increasing the first addition amount of inlet water and increasing the washing time for a first time period; if the turbidity value is not in the first set range or the second set range, the second addition amount of the inlet water is increased and the washing time is increased for a second time period; and (5) continuing washing after adjusting washing parameters. Of course, the adjustment of the above ranges and parameters can be set as required, and is not limited herein.

And in the main washing stage, detecting whether the washing time is up or not in real time, and if so, stopping washing. Wherein the washing time period comprises the initially set time period plus the time period increased in the process of the intermediate adjusting parameter. Before the washing time is not reached, the circulating pump is in the running state.

Referring to fig. 4, after the main washing stage is completed, there are contaminants and detergent residues on the articles, so the rinsing stage includes at least two rinses to wash the detergent clean. In this embodiment, the number of additional rinses may be determined based on the turbidity value. The greater the turbidity value, the more additional rinsing cycles should be, and if the additional rinsing cycles are one, at least three rinsing cycles are required. Here, a range of the turbidity value may be set, and the number of times of rinsing that needs to be increased is determined according to the range of the turbidity value detected in the main washing stage. For example, when water is fed in the rinsing process, the turbidity value detected in the main washing stage is judged, and if the turbidity value is within a first set range, the number of times of rinsing is not required to be increased, and water is fed continuously for normal rinsing; if the turbidity value is not in the first set range, adding one time of rinsing, and arranging the increased rinsing before the normal rinsing, and after the increased rinsing finishes the drainage, continuing the water inlet for the normal rinsing.

During the rinsing process, heating may be performed in order to better clean the residue of the contaminants; however, if the heating is performed every time the rinsing is performed, the electric energy is wasted. Therefore, the range of the turbidity value can be set, and whether the rinsing stage needs heating or not is judged according to the turbidity value detected in the main washing stage; if heating is required, it is only the first rinsing to heat, or both the first rinsing and the second rinsing to heat. If the turbidity value is within a first predetermined range, heating is carried out at least during the first rinsing. Alternatively, the turbidity value may be detected during the first rinsing and it may be determined from the turbidity value whether the rinsing stage requires heating.

The first setting range is used for determining the number of times of additional rinsing, the first preset range is used for determining whether heating is performed during rinsing, and the first setting range and the first preset range can be set according to actual conditions.

In the embodiment, the duration of the pre-washing stage is not more than 10min, the duration of the main washing stage is not less than 50min, and the duration of each rinsing stage is not more than 10min. Of course, the time length is not limited here, and can be set according to actual situations.

The embodiment of the invention also provides a dishwasher, and the dishwasher washing control method is adopted for washing. Through before the main stage of washing, set up the pre-washing stage, can wash away and wait to wash great foul matter on the article, prevent that great foul matter from causing the influence to follow-up turbidity detection, improve washing efficiency and clean effect. The dishwasher includes a temperature detector and a turbidity detector for detecting the temperature and turbidity of the washing water; the dishwasher further includes a water level sensor or a flow sensor for detecting the amount of water fed.
