Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
Example 1
Embodiment 1 of the present invention provides a method for controlling a dishwasher, fig. 1 is a schematic flow chart of the method for controlling a dishwasher in embodiment 1 of the present invention, and as shown in fig. 1, the method for controlling a dishwasher in embodiment 1 of the present invention includes the following steps:
s101: in the process of executing a normal washing program by the dishwasher, when a door of the dishwasher is changed from an open state to a closed state, the actual temperature of water in an inner container of the dishwasher is obtained.
Generally, a dishwasher may have a plurality of washing modes, each of which has a corresponding washing control program. After the dishwasher acquires a mode selection instruction of a user, the dishwasher executes a washing control program corresponding to a washing mode selected by the user to perform normal washing. In embodiment 1 of the present invention, a plurality of washing patterns pre-stored in the dishwasher may be regarded as a normal washing pattern.
In embodiment 1 of the present invention, in the process of executing the normal washing program by the dishwasher, the water is generally located at the bottom of the inner container of the dishwasher, and the water at the bottom of the inner container of the dishwasher is sprayed onto the dishes in the inner container through the spraying device under the action of the washing pump to wash the dishes, so that the actual temperature of the water at the bottom of the inner container of the dishwasher is obtained in S101.
S102: and when the actual temperature is greater than a preset temperature threshold value, adjusting the rotating speed of the washing pump to a first rotating speed, wherein the first rotating speed is less than the current rotating speed of the washing pump.
In embodiment 1 of the present invention, the temperature threshold is 0 ℃ or more, for example, 10 to 50 ℃, and specifically, 10 ℃, 20 ℃, 30 ℃, 40 ℃, 50 ℃.
That is, when the actual temperature of the water at the bottom of the dishwasher tank is greater than the temperature threshold, the rotation speed of the washing pump needs to be adjusted down. This is because, in the washing process of the dishwasher, when the door of the dishwasher is changed from the open state to the closed state, the process of heat exchange between the water in the inner tub of the dishwasher and the cold air is related to the rotation speed of the washing pump, and after the rotation speed of the washing pump is reduced, the rate of heat exchange between the water and the cold air is reduced, so that the cold air entering through the door opening is not rapidly heated and expanded by the hot water, and the exhaust hole is not generated to have no time to exhaust the excessive gas, thereby pushing the door body open.
S103: controlling the rotation speed of the washing pump to increase on the basis of the first rotation speed according to a preset rule.
In the process of increasing the rotation speed of the washing pump based on the first rotation speed, the washing water pressure is increased along with the increase of the rotation speed of the washing pump.
As a specific embodiment, the controlling of the rotation speed of the washing pump to increase on the basis of the first rotation speed according to a preset rule includes: controlling the wash pump to increase stepwise to the current speed on the basis of the first speed. Wherein, stepwise growth can be understood as: and increasing the preset rotating speed increasing amount every preset time period.
As another specific embodiment, the controlling of the rotational speed of the washing pump to increase on the basis of the first rotational speed according to a preset rule includes: controlling the wash pump to linearly increase to the current speed based on the first speed. Wherein said linear growth can be understood as: growing in the form of a linear function y-kx + b.
As another specific embodiment, the controlling of the rotational speed of the washing pump to increase on the basis of the first rotational speed according to a preset rule includes: controlling the wash pump to exponentially increase to the current speed based on the first speed. Wherein said exponential increase may be understood as: the rate at which a variable increases is proportional to its number at that time.
That is, when the actual temperature of the water at the bottom of the inner tub of the dishwasher is greater than the temperature threshold, the rotation speed of the washing pump needs to be gradually increased after the rotation speed of the washing pump is adjusted to be low, because the temperature difference between the water and the cold air is gradually decreased as the heat exchange between the water and the cold air is progressed, and the cold air is not rapidly heated and expanded to push the door body open even if the rotation speed of the washing pump is increased.
As a further embodiment, after controlling the rotation speed of the washing pump to increase on the basis of the first rotation speed according to a preset rule, the method further comprises: continuing to execute the normal washing program.
As a further embodiment, the dishwasher controlling method of embodiment 1 of the present invention further includes the steps of: and when the actual temperature is less than or equal to the temperature threshold value, controlling the dishwasher to continue washing according to the current washing program.
This is because, when the actual temperature of the water in the inner tub of the dishwasher is lower than the temperature threshold, the cold air cannot be heated rapidly by washing in the normal washing mode, the expansion pressure of the gas does not reach the ability of pushing the door catch open, so the current water temperature is less than or equal to the preset temperature, and the dishwasher directly performs normal washing according to the washing mode selected by the user.
As a specific embodiment, before controlling the rotation speed of the washing pump to increase on the basis of the first rotation speed according to a preset rule, the method further includes: and calculating the difference value between the actual temperature and the temperature threshold value, and determining the increase level of the first rotating speed according to the difference value.
Specifically, the following technical scheme may be adopted to determine the increase level of the first rotation speed according to the difference value: determining the interval to which the difference value belongs; and determining the increase level of the first rotating speed according to the corresponding relation between the preset temperature interval and the increase level.
Example 1: when the difference value is more than or equal to 10 and less than 20, the starting program 1 adopts a first growth level for growth, and the specific starting program 1 is as follows: the initial rotation speed of the pump is 2000 revolutions for 5 seconds; 2200 turns, 5 seconds turns; 2400 revolutions, 5 seconds … … up to 3000 revolutions; when the difference value is more than or equal to 20 and less than 30, the starting program 2 adopts a second growth level for growth, and the specific starting program 2 is as follows: the initial rotation speed of the pump is 2000 revolutions for 7.5 seconds; 2200 turns, 7.5 seconds turns; 2400 revolutions, 7.5 seconds … … up to 3000 revolutions; when the difference value is more than or equal to 30 and less than 40, the starting program 3 adopts a third growth level for growth, and the specific starting program 3 is as follows: the initial rotation speed of the pump is 2000 revolutions for 10 seconds; 2200 turns, turn for 10 seconds; 2400 revolutions, 10 seconds … … up to 3000 revolutions, and so on.
Example 2: when the difference value is more than or equal to 10 and less than 20, the starting program 4 adopts a first growth level for growth, and the specific starting program 4 is as follows: the initial rotation speed of the pump is 2000 revolutions for 5 seconds; 2150 turns, 5 seconds turns; 2300 revolutions, 5 seconds … … up to 3000 revolutions; when the difference value is more than or equal to 20 and less than 30, the starting program 5 adopts a second growth level for growth, and the specific starting program 5 is as follows: the initial rotation speed of the pump is 2000 revolutions for 5 seconds; 2100 turns for 5 seconds; 2200 revolutions, 5 seconds … … up to 3000 revolutions; when the difference value is more than or equal to 30 and less than 40, the starting program 6 adopts a third growth level for growth, and the specific starting program 6 is as follows: the initial rotation speed of the pump is 2000 revolutions for 5 seconds; 2050 revolutions and 5 seconds revolutions; 2100 revolutions, 5 seconds … … up to 3000 revolutions, and so on.
As can be seen from the above examples 1 and 2, when the temperature difference is small, a level of increase in which the step increase is fast may be selected; when the temperature difference is larger, the increasing level with slower step increasing can be selected. That is to say, when the temperature difference is small, more time is not wasted for protection, the total washing time is effectively optimized, and unnecessary energy waste can be reduced.
Meanwhile, as can be seen from example 1 and example 2, the difference between different growth levels may be the following two types: the first is that the rotational speed increases by the same amount between different increasing levels, for example 1, each increase is 200 revolutions, but the dwell time at the same rotational speed is different and increases with increasing level, and the three different increasing levels are 5 seconds, 7.5 seconds and 10 seconds respectively. The second is that the time of the same rotation speed is not changed for different increasing levels, for example 2, the time is 5 seconds, but the rotation speed increasing amount is different between the different increasing levels, and the three different increasing levels are 50 revolutions, 100 revolutions and 150 revolutions respectively.
To explain the control method of the dishwasher of embodiment 1 of the present invention in more detail, a specific example is given. Fig. 2 is a schematic flowchart of an example of a method for controlling a dishwasher according to embodiment 1 of the present invention, and as shown in fig. 2, the method for controlling the dishwasher includes the steps of:
s1: when the dishwasher is in a washing stage, if the state of a door of the dishwasher is detected to be changed from an open state to a closed state, the current water temperature at the bottom of an inner container of the dishwasher is detected and judged.
S2: and if the current water temperature at the bottom of the inner container is judged to be higher than the preset temperature (namely the preset temperature threshold), controlling a washing pump of the dish washing machine to wash according to the preset stepped increasing rotating speed, and gradually increasing the rotating speed to the normal washing program rotating speed.
S3: and if the current water temperature at the bottom of the inner container is judged to be less than or equal to the preset temperature, controlling the dish-washing machine to enter a normal washing program.
This is because, when the temperature of the water in the bottom of the inner container is low, the cold air cannot be heated rapidly by the normal washing program, the expansion pressure of the air cannot reach the capability of pushing the door latch, so the current water temperature is less than or equal to the preset temperature, and the dishwasher directly performs the normal washing according to the washing program selected by the user.
That is to say, the dish washer can wash according to the washing procedure that the user selected after the electricity starts, in the washing stage, after the door of dish washer was opened and was closed again, detectable dish washer's door state becomes closed state by the open mode, judge based on the current temperature of inner bag bottom this moment, if judge the current temperature of inner bag bottom and be greater than preset temperature, control dish washer washing pump motor rotational speed and operate with certain lower rotational speed, and step-by-step increase washing pump rotational speed, slow down the process that the cold air is heated inflation, finally reach former normal washing procedure and set for the rotational speed, control dish washer washes with normal washing procedure.
FIG. 3 is a schematic flow chart of the stepwise increase of the rotation speed of the washing pump, as shown in FIG. 3, when the door state of the dishwasher at the washing stage is detected to be changed from an open state to a closed state, the dishwasher immediately detects the water temperature TN at the bottom of the inner container, and when the water temperature is greater than the preset water temperature TS, the rotation speed of the motor of the washing pump of the dishwasher is controlled to ri, and the motor is operated for Ti time; and detecting whether the current rotating speed is the motor rotating speed rS set by the original washing program, if not, controlling the washing pump to increase the rotating speed ro, and then running the Ti time, otherwise, entering the normal washing program. For example, after the door is opened and closed halfway, if the water temperature at the bottom of the inner container of the dishwasher is detected to be higher than the preset water temperature TS (for example, TS is 40 ℃), the increased rotating speed ro is set to be 200 revolutions, and the rotating speed rS of the motor set by the original washing program is set to be 3000 revolutions; controlling the rotating speed ri of the washing pump motor to be 2000 revolutions, and controlling the running time Ti to be 5 seconds, and increasing the rotating speed of the washing pump motor to 2200 revolutions after running for 5 seconds; and running for 5 seconds, increasing the rotating speed of the washing pump motor from 2200 to 2400 revolutions, circulating … … in such a way, finally increasing 3000 revolutions, and continuously executing the originally set washing program.
