Description

Technical Field

[0001] The present invention relates to the technical field of cleaning machines, and in particular to a cleaning method of a cleaning machine. Background Art

[0002] As people's living standards continue to improve, dishwashers, fruit and vegetable washing machines and other washing machines are widely used. Current washing machines usually work according to the set cleaning program. In different cleaning stages, the power, temperature, speed and other parameters of the washing pump in the washing machine are adjusted accordingly to match the different requirements of different cleaning stages. However, there is usually no logical relationship between the cleaning parameters in different cleaning stages, and they cannot complement each other in the cleaning process, and the cleaning effect is average. Especially in the main washing stage of the actual cleaning process, due to the placement of cleaning agents, bubbles are serious during the cleaning process, and the power of the cleaning pump will become lower and lower during operation, so that the cleaning results are average and the energy consumption is high. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a cleaning method for a cleaning machine capable of adjusting subsequent cleaning parameters according to the previous cleaning conditions so as to ensure the cleaning effect while reducing energy consumption, in view of the above-mentioned prior art.

[0004] The technical solution adopted by the present invention to solve the above technical problems is: a cleaning method for a cleaning machine, characterized in that the cleaning machine includes a main washing stage of adding a cleaning agent for cleaning and a rinsing stage after the main washing stage;

[0005] In the main wash stage, the cleaning pump in the cleaning machine is controlled to work at the set speed corresponding to this stage, and the working power P of the cleaning pump is detected in real time, and P is compared with the maximum power threshold P corresponding to this stage. H , minimum power threshold P L Make comparisons;

[0006] If P L ≤P≤P H , then the cleaning pump is controlled to continue working at the current set speed;

[0007] If P>P H , then control to reduce the speed of the cleaning pump;

[0008] If P < P L , the control ends the main wash stage and starts the rinsing stage, and the remaining time of the main wash stage is added to the rinsing stage.

[0009] In order to ensure the cleaning time of the main washing stage as much as possible and achieve better cleaning effect, especially better cleaning effect on oil stains, the working time t of the cleaning pump in this stage is obtained in real time during the main washing stage;

[0010] When P<P L When t is equal to T1, T1 is the set working time of the main wash stage;

[0011] If t≥k*T1, 0<k<1, the control directly ends the main wash stage and starts the rinsing stage, and adjusts the working time T of the rinsing stage to: T=T2+T1-t; where T2 is the set working time of the rinsing stage;

[0012] If t<k*T1, the control adds water into the cleaning machine and continues the main wash phase.

[0013] The number of times water is added is flexibly accumulated and calculated. If the number of times water is added reaches the set number K, where K is a positive integer, the number of times water is added is reset to zero. At the same time, the main wash phase is controlled to end and the rinsing phase is started, and the working time T of the rinsing phase is adjusted to: T=T2+T1-t.

[0014] Preferably, when P>P H When the speed of the cleaning pump is reduced according to the set speed adjustment amount, the working power P of the cleaning pump meets P L ≤P≤P H .

[0015] Compared with the prior art, the advantages of the present invention are: the cleaning method of the cleaning machine of the present invention, in the main washing stage of cleaning with a cleaning agent, according to the working power P of the cleaning pump and the minimum power threshold P L The relationship between P and P can effectively determine whether the cleaning pump is idling due to foam. L At this time, it is determined that the cleaning pump is likely to idle due to the foam. At this time, the cleaning machine is controlled to end the main wash stage and start the rinsing stage, which can reduce the idling energy consumption of the cleaning pump when it cannot play a cleaning role. At the same time, in this case, the remaining time of the main wash stage is increased to the rinsing stage, which extends the working time of the rinsing stage. That is, the cleaning effect can be effectively guaranteed without increasing the overall cleaning time of the cleaning machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is the standard cleaning curve of the cleaning machine in the embodiment of the present invention.

[0017] Figure 2 Flow chart of a cleaning method of a cleaning machine in an embodiment of the present invention. DETAILED DESCRIPTION

[0018] The present invention is further described in detail below with reference to the accompanying drawings.

[0019] Existing cleaning machines mainly include sink-type cleaning machines, embedded cleaning machines, fruit and vegetable cleaning machines, etc. Cleaning machines usually include several cleaning stages in sequence, namely, soaking stage, main washing stage, rinsing stage, sterilization stage, etc. Depending on the cleaning object, the soaking stage or sterilization stage can be deleted accordingly.

[0020] Before the product leaves the factory, the corresponding standard cleaning curve will be stored in the cleaning machine for different cleaning scenarios. The cleaning curve is composed of cleaning parameters, such as the set working time, working temperature, cleaning pump speed, working power, etc. of each cleaning stage.

[0021] like Figure 1 As shown in the figure, under normal circumstances, the working characteristics of the soaking stage are: the cleaning pump rotates at a low speed, and the speed can be selected between 1000 and 1400 r / min, so as to fully soak and soften the surface pollutants of the objects to be cleaned in the cleaning machine, so as to facilitate subsequent cleaning work. The working characteristics of the main washing stage are: heating the water temperature to the set temperature, controlling the cleaning pump to rotate at a high speed, and maintaining the corresponding working power of the cleaning pump at the set maximum power threshold P H and the minimum power threshold P L When the temperature is between 20℃ and 80℃, the pollutants can be effectively cleaned under the action of the cleaning agent. The working characteristics of the rinsing stage are: the water temperature is maintained at the set temperature. According to different models, the temperature can be set within 25-60℃, and the cleaning pump is controlled to rotate at a high speed to rinse the cleaning agent, pollutants, etc. on the surface of the object to be cleaned, so as to achieve the purpose of thoroughly cleaning the object to be cleaned. The working characteristics of the sterilization stage are: a certain temperature and impact strength are required. During the operation, the cleaning temperature is set between 60 and 70℃, and the cleaning speed is set between 2500 and 3000r / min.

[0022] As mentioned above, the cleaning machine includes at least a main wash phase in which a cleaning agent is added for cleaning and a rinsing phase after the main wash phase.

[0023] like Figure 2 As shown, the cleaning method of the cleaning machine in this embodiment includes the following steps:

[0024] S1. In the main wash stage, the heating plate can be controlled to heat the water in the washing machine cavity. In this embodiment, the heating temperature is set to 40°C. When the temperature reaches 40°C, the heating plate stops heating, and then the washing operation is continued without heat preservation;

[0025] S2, controlling the cleaning pump in the cleaning machine to work at a set speed corresponding to the main wash stage, and detecting the working power P of the cleaning pump in real time, and obtaining the working time t of the cleaning pump in the main wash stage in real time;

[0026] P is the maximum power threshold P of the power range that can play a cleaning role in the main wash stage.H , minimum power threshold P L Make comparisons;

[0027] If P L ≤P≤P H , it means that the cleaning pump can play a good role in cleaning the objects to be cleaned at this time, so the cleaning pump is controlled to work continuously at the current set speed, and it is judged whether the current t reaches the set working time T1 corresponding to the main washing stage. If it reaches, it enters the rinsing stage, if not, it goes to S2;

[0028] If P>P H , it means that the energy consumption of the cleaning pump is too high, and then proceed to S3;

[0029] If P < P L , it means that the cleaning pump is likely to run idle due to the foam of the cleaning machine, which will cause the dishes to be not cleaned cleanly and waste energy. At this time, S4 is performed;

[0030] S3, control to reduce the speed of the cleaning pump; specifically, the speed of the cleaning pump can be controlled to reduce the speed according to the set speed adjustment amount V0 until the working power P of the cleaning pump meets P L ≤P≤P H , in this embodiment, V0 = 100r / min;

[0031] S4, controlling the main wash phase to end and the rinsing phase to start, and adding the remaining time of the main wash phase to the rinsing phase;

[0032] In order to avoid the situation that P<P L In this case, directly ending the main wash phase and starting the rinsing phase may not guarantee a good cleaning effect. Based on this, the following method is used in this embodiment to solve the problem:

[0033] When P<P L When t is equal to T1, T1 is the set working time of the main wash stage.

[0034] If t≥k*T1, 0<k<1, in this embodiment, k=1 / 2; t≥k*T1 indicates that the main wash stage time has passed halfway, and the cleaning work in the main wash stage can already meet the basic cleaning requirements of the objects to be cleaned. At this time, the control directly ends the main wash stage and performs the rinsing stage work, and the working time T of the rinsing stage work is adjusted to: T=T2+T1-t; wherein T2 is the set working time of the rinsing stage; extending the working time of the rinsing stage can effectively make up for the inadequate cleaning in the main wash stage, thereby achieving an excellent cleaning effect on the objects to be cleaned;

[0035] If t<k*T1, it means that the cleaning time of the main wash stage is too short and cannot effectively meet the basic cleaning requirements of the objects to be cleaned. In this case, the cleaning time of the main wash stage needs to be extended as much as possible. In order to ensure that the cleaning pump can continue to perform the main wash work when it has been idling, water is added to the cleaning machine and the main wash stage is continued. The amount of water added each time is controlled according to the set water addition amount L0. For example, 0.5-1L of water can be added each time according to the need, so as to extend the cleaning time of the main wash stage as much as possible.

[0036] In this embodiment, the number of water additions is accumulated and calculated. If the number of water additions reaches a set number K, K is a positive integer, and K=3 in this embodiment, the number of water additions is reset to zero, and the main wash stage is controlled to end and the rinsing stage is performed, and the working time T of the rinsing stage is adjusted to: T=T2+T1-t. Setting the set number of water additions K can achieve a balance between the idling energy consumption of the washing pump and extending the cleaning working time of the main wash stage as much as possible;

[0037] S5. Control the cleaning pump to work according to the working parameters corresponding to the rinsing stage, and adjust the working time T of the rinsing stage to: T=T2+T1-t.

[0038] The cleaning method of the cleaning machine of the present invention, in the main washing stage of cleaning with a cleaning agent, according to the working power P of the cleaning pump and the minimum power threshold P L The relationship between P and P can effectively determine whether the cleaning pump is idling due to foam. L When the cleaning pump is judged to be idling due to the foam, the cleaning machine is controlled to end the main wash stage and start the rinsing stage, which can reduce the idling energy consumption of the cleaning pump when it cannot play a cleaning role. At the same time, in this case, the remaining time of the main wash stage is added to the rinsing stage, which prolongs the working time of the rinsing stage, that is, the cleaning effect can be effectively guaranteed without increasing the overall cleaning time of the cleaning machine. In the cleaning method of the cleaning machine, the working parameters of the subsequent cleaning stage can be adjusted according to the working conditions of the previous cleaning stage, so that different cleaning stages interact with each other, and the invalid cleaning stage can be ended in time. At the same time, the subsequent cleaning stage is used to make up for the shortcomings of the cleaning work in the previous cleaning stage, so as to avoid energy waste and ensure the cleaning effect.
