[0028] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] As the quality of life continues to improve, more and more families choose to use dishwashers to clean dishes efficiently. The current washing method of dishwashers is mainly to use washing liquid to directly rinse the dishes to achieve the purpose of washing. Alternatively, some dishwashers will heat the washing liquid and use the heated washing liquid to rinse the dishes to improve the washing effect. However, the above method can effectively clean general pollutants, but there is a problem of poor cleaning effect for stubborn pollutants.

[0030] In order to improve the cleaning effect, the prior art generally improves the cleaning effect by increasing the temperature of the washing liquid and / or using a high-pressure water flow. Alternatively, in some modes, the prior art can also achieve the effect of softening and removing highly adhesive pollutants by extending the soaking time. However, although the above methods improve the cleaning effect, they also increase energy consumption and water resource consumption.

[0031] Therefore, how to improve the cleaning effect of the dishwasher during the washing process on the basis of ensuring the optimal utilization of resources has become a problem to be solved urgently. In order to solve the above technical problems, the inventive concept of the washing control method applied to the dishwasher provided in the embodiment of the present application is to add a heating element to the dishwasher. The dishwasher can turn on the heating element during the washing stage so that the washing liquid in the washing process can be vaporized by contacting the heating element. The vaporized washing liquid can more fully contact and react with the pollutants to achieve the effect of softening the pollutants, thereby improving the cleaning effect of the pollutants. And, a fan can also be added to the dishwasher. The dishwasher can turn on the fan when the heating element is turned on and the heating process is performed. The fan can assist the heating element in heating to avoid the heating element from heating up too fast and causing the temperature to be too high. The dishwasher can also turn on the fan during the vaporization of the washing liquid. The fan can accelerate the diffusion of the vaporized washing liquid inside the dishwasher, thereby improving the contact efficiency between the pollutants and the vaporized washing liquid.

[0032] The controller is used as the execution subject to execute the washing control method applied to the dishwasher in the following embodiment. Specifically, the execution subject may be a hardware device of the controller, or a software application in the controller that implements the following embodiment, or a computer-readable storage medium that is installed with the software application that implements the following embodiment, or a code of the software application that implements the following embodiment.

[0033] The technical solution of the present application is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0034] Figure 1 The flowchart of a washing control method applied to a dishwasher provided by an embodiment of the present application is shown. With the controller as the execution body, the method of this embodiment may include the following steps:

[0035] S101, controlling a heating element inside the dishwasher to heat, and controlling a washing pump in the dishwasher to spray washing liquid to vaporize the washing liquid.

[0036] In this embodiment, the controller can control the heating element inside the dishwasher to heat up. The heating of the heating element can increase the temperature of the heating element itself.

[0037] The controller can also control the washing pump in the dishwasher to spray washing liquid. The washing pump may include one or more spray arms. Optionally, the spray arm can be arranged at the bottom or top of the dishwasher. Optionally, when the dishwasher includes multiple layers of dish racks, the spray arm can also be arranged at the bottom of other dish racks except the bottom dish rack. Optionally, the spray arm arranged at the bottom of the dish rack can be arranged downward to rinse the tableware placed in the dish rack below the dish rack. Optionally, the washing pump can output washing liquid to each spray arm so that each spray arm sprays washing liquid, thereby achieving the cleaning of the tableware inside the dishwasher.

[0038] Optionally, the washing liquid may be clean water. Alternatively, the washing liquid may be clean water mixed with detergent. Alternatively, the composition of the washing liquid may be set according to different washing stages. For example, in the pollutant softening stage, the washing liquid may be clean water mixed with detergent. For another example, in the pollutant rinsing stage, the washing liquid may be clean water.

[0039] When the heating element is heated, the washing liquid sprayed from the washing pump can be vaporized when contacting the heating element to form vaporized washing liquid. Optionally, the vaporized washing liquid can be steam. Optionally, the operation of controlling the heating element to heat so that the washing liquid sprayed from the washing pump is vaporized when contacting the heating element can be performed during the pollutant softening stage.

[0040] In one example, the controller can control the washing liquid sprayed from the washing pump while controlling the heating of the heating element. This method can better control the water spraying time of the washing pump during the pollutant softening stage. However, during this process, the heating element is continuously heated. If the washing liquid sprayed by the washing pump takes away enough temperature in time, the temperature of the heating element may be too high, resulting in overheating and damage to the heating element. Also, during this process, the washing pump continues to spray washing liquid on the heating element, which may also cause the heat of the heating element to be quickly taken away. The heating efficiency ensures that the heating element is continuously at a temperature that can vaporize the washing liquid, resulting in a decrease in the vaporization efficiency of the washing liquid, and the cleaning effect of the present application cannot be achieved.

[0041] In another example, the controller may alternately perform the process of heating the heating element and spraying water by the washing pump, thereby ensuring that the heating element is in a suitable temperature range and the vaporization efficiency of the washing liquid is ensured. The specific process may include the following steps:

[0042] Step 11, repeat the following steps until a preset condition is reached. The preset condition is that a preset number of repetitions is reached. Optionally, the number of repetitions can be determined according to the element parameters of the heating element. For example, the number of repetitions can be 5 times, 6 times, 7 times, etc. Alternatively, the preset condition is that the total heating time of the heating element is greater than the total preset time. Optionally, the total heating time can be determined according to the element parameters of the heating element. For example, the total heating time can be 1 minute, 3 minutes, 5 minutes, etc.

[0043] Step 12: During the process of controlling the heating element to heat, if it is determined that the temperature of the heating element is greater than a first preset temperature, the heating element is controlled to stop heating, and the washing pump is controlled to spray washing liquid, wherein the first preset temperature is greater than or equal to the vaporization temperature of the washing liquid.

[0044] Step 13: When it is determined that the temperature of the heating element is less than the second preset temperature, the washing pump is controlled to stop working, and the heating element is controlled to heat. The second preset temperature is less than the first preset temperature. Specifically, the first preset temperature and the second preset temperature can be determined according to a vaporization test of the washing liquid. When the heating element is at the first preset temperature, the vaporization ratio of the washing liquid is high. When the heating element is at the second preset temperature, the vaporization ratio of the washing liquid is low.

[0045] In one example, the controller can also adjust the amount of washing liquid sprayed by the washing pump in the dishwasher according to the time it takes for the heating element to drop from the first preset temperature to the second preset temperature, thereby ensuring that the time it takes for the heating element to drop from the first preset temperature to the second preset temperature is uniform, thereby ensuring the vaporization efficiency of the washing liquid. The process may specifically include the following steps:

[0046] Step 21, adjusting the speed of the washing pump according to the cooling time of the heating element, wherein the cooling time is the time taken for the heating element to cool from a first preset temperature to a second preset temperature, wherein the first preset temperature is greater than or equal to the vaporization temperature of the washing liquid.

[0047] In this step, the controller can start timing from the time when the heating element ends heating, and record the cooling time of the heating element. Optionally, the timer in the controller can record the cooling time in real time, and stop timing when the heating element starts heating.

[0048] The controller can adjust the speed of the washing pump according to the cooling time. Optionally, when the speed of the washing pump is accelerated, the amount of washing liquid sprayed by the washing pump increases. When the speed of the washing pump is slowed down, the amount of washing liquid sprayed by the washing pump decreases. Optionally, the process from the heating element stopping heating, the washing pump starting, the heating element starting heating to the heating element stopping heating next time can be made into a cycle. The controller can obtain the cooling time from the heating element stopping heating to starting heating in the previous cycle. The controller can adjust the speed of the washing pump according to the cooling time in the previous cycle before the washing pump of this cycle is started.

[0049] Specifically, if it is determined that the cooling time is less than the first preset time, the speed of the washing pump is reduced. Optionally, the first preset time can be a shorter time. When the cooling time is less than the first preset time, it means that the washing pump has achieved rapid cooling. Since the heating element is not heated during the operation of the washing pump, the heat of the heating element from the first preset temperature to the second preset temperature is fixed. The rapid cooling means that too much washing liquid quickly takes away the temperature of the heating element. However, too fast a temperature reduction is likely to cause too frequent switching between the heating element and the washing pump, which can easily damage the heating element and the washing pump. In addition, since the surface area of ​​the heating element is limited, the flushing of too much washing liquid not only quickly takes away the temperature of the heating element, but also the excessive washing liquid divides the heat equally and reduces the efficiency of vaporization. Therefore, at this time, it is necessary to reduce the speed so as to reduce the washing liquid sprayed by the washing pump to extend the cooling time.

[0050] Optionally, a speed step length may be provided in the controller. The controller may reduce the speed of the washing pump according to the speed step length. For example, the speed step length may be 200 rpm, 300 rpm, etc. Optionally, the speed adjustment process of the washing pump may be shown in the following formula:

[0051] r=r-r0

[0052] Wherein, r represents the speed of the washing pump in the previous cycle, and r0 represents the speed step.

[0053] Specifically, if it is determined that the cooling time is longer than the second preset time, the speed of the washing pump is increased. Optionally, the second preset time can be a longer time. When the cooling time is longer than the second preset time, it means that the cooling speed of the washing pump is too slow. The slow cooling means that too little washing liquid contacts the heating element. Although the slow cooling speed can ensure the contact between the washing liquid and the heating element and the vaporization efficiency, the small amount of sprayed washing liquid itself will also lead to a decrease in the contact efficiency between the washing liquid and the tableware inside the dishwasher, thereby affecting the cleaning efficiency of the dishwasher. Therefore, at this time, it is necessary to increase the speed so that the washing liquid sprayed by the washing pump increases to shorten the cooling time.

[0054] Optionally, when the cooling time is longer than the second preset time, when the cooling time reaches the second time, the temperature of the heating element is usually still at a stage greater than the second preset temperature. Therefore, at this time, the controller can control the washing pump to turn off and turn on the heating element in response to the trigger condition that the cooling time is longer than the second preset time to enter the next cycle. That is, at this time, the controller cannot control the washing pump to stop working and control the heating element to heat by the condition that the heating element is less than the second preset temperature.

[0055] Optionally, the process of the controller increasing the speed of the washing pump according to the speed step can be expressed as follows:

[0056] r=r+r0

[0057] Wherein, r represents the speed of the washing pump in the previous cycle, and r0 represents the speed step.

[0058] Step 22: According to the adjusted rotation speed, control the washing pump to spray washing liquid.

[0059] In this step, when the washing pump is started, the controller can rotate according to the adjusted speed and spray out the washing liquid.

[0060] In one example, during the process of controlling the heating element inside the dishwasher to heat, the fan inside the dishwasher is controlled to continuously blow air to the heating element.

[0061] In this example, a fan may be provided inside the dishwasher. The controller may synchronously control the fan to start when the heating element is turned on. Optionally, the fan may continue to blow air to the heating element while it is turned on. The blowing setting may prevent the heating element from heating up too quickly during the heating process.

[0062] In the actual execution process, the controller needs to receive the information that the temperature of the heating element reaches the first preset temperature before sending the instruction to stop heating to the heating element. Therefore, after the heating element reaches the first preset temperature and before receiving the instruction to stop heating, the heating element will be in a continuous heating state. In the case where the heating efficiency of the heating element is high, the temperature of the heating element may exceed the safe temperature. At this time, the setting of the fan can slow down the heating speed of the heating element to ensure that the heating element does not exceed the safe temperature before receiving the instruction to stop heating.

[0063] Optionally, the fan can be turned off when the heating element stops heating. Alternatively, the controller can keep the fan in an activated state.

[0064] In one example, while controlling a washing pump in a dishwasher to spray washing liquid, a fan inside the dishwasher is controlled to continuously blow air.

[0065] In this example, the controller can synchronously control the fan to start when the washing pump is started. Alternatively, the controller can also synchronously start the fan when the heating element is turned on, and then keep the fan in operation. Optionally, the fan can blow air toward the heating element during the process of the washing pump spraying the washing liquid, so that the vaporized washing liquid can be blown away by the fan, and the efficiency of diffusion into the dishwasher is improved, the air circulation is accelerated, and the vaporized washing liquid is fully combined with the pollutants.

[0066] Optionally, the fan can be turned off when the washing pump stops working. Alternatively, the controller can keep the fan in a started state.

[0067] S102: When it is determined that the dishwasher meets the preset conditions, the heating element is controlled to stop working, and the dishwasher is controlled to perform subsequent washing tasks.

[0068] In this embodiment, the preset condition is that the preset number of repeated executions is reached. Optionally, the number of repeated executions can be determined according to the element parameters of the heating element. For example, the number of repeated executions can be 5 times, 6 times, 7 times, etc. Alternatively, the preset condition is that the total heating time of the heating element is greater than the total preset time. Optionally, the total heating time can be determined according to the element parameters of the heating element. For example, the total heating time can be 1 minute, 3 minutes, 5 minutes, etc.

[0069] The controller can control the heating element to stop working when it is determined that the heating element of the dishwasher reaches the preset condition. At this time, it indicates that the dishwasher ends the pollutant softening stage. The controller can control the dishwasher to perform subsequent washing tasks.

[0070] In one example, the subsequent washing task of the dishwasher may include the following three actions:

[0071] First, the fan inside the dishwasher is controlled to blow air, and after a third preset time, the fan is controlled to stop working. Optionally, the third time of blowing is used to further accelerate air circulation, so that the vaporized washing liquid diffuses into the dishwasher and fully combines with the pollutants.

[0072] Second, control the dishwasher to perform the rinsing task.

[0073] Third, control the dishwasher to perform the drying task.

[0074] Optionally, the drying task may be performed as follows: Figure 2 As shown, the process includes the following:

[0075] Optionally, in the process of controlling the dishwasher to perform a drying task, if it is determined that the humidity inside the dishwasher is greater than or equal to a first preset humidity, the heating element is controlled to heat, and the fan inside the dishwasher is controlled to blow air. The controller may obtain the humidity inside the dishwasher when the drying task is started. Figure 2 As shown, the humidity can be expressed as H. A first preset humidity can be preset in the controller. The first preset humidity can be expressed as H0. The first humidity is a value greater than the ambient humidity. The controller can compare the humidity H inside the dishwasher with the first preset humidity H0. If the humidity H inside the dishwasher is greater than or equal to the first preset humidity H0, the controller can control the heating element to heat and control the fan inside the dishwasher to blow air. The heating of the heating element can be used to increase the temperature inside the dishwasher, so that more residual liquid inside the dishwasher is converted into steam. Turning on the fan can accelerate air circulation and allow more hot air to enter the condensation channel, thereby accelerating the drying of the tableware and preventing steam from overflowing when the door is opened.

[0076] In one implementation, the process of turning on the heating element and the fan can continue until the humidity is less than a second preset humidity. Optionally, the second preset humidity is determined according to the ambient humidity. The first preset humidity is greater than the second preset humidity.

[0077] In another implementation, the process of turning on the heating element and the fan may continue until the humidity is lower than a first preset humidity.

[0078] Optionally, in the process of controlling the dishwasher to perform the drying task, if it is determined that the humidity inside the dishwasher is less than a first preset humidity, the fan inside the dishwasher is controlled to blow air. If the humidity H inside the dishwasher is less than the first preset humidity H0, and the temperature inside the dishwasher is greater than a second preset temperature, the controller can control the fan to start alone. Turning on the fan can accelerate air circulation, allowing more hot air to enter the condensation channel, thereby accelerating the drying of the dishes and preventing steam from overflowing when the door is opened.

[0079] In one implementation, the fan may be turned on until the humidity is lower than a second preset humidity.

[0080] Optionally, in the process of controlling the dishwasher to perform the drying task, if it is determined that the humidity inside the dishwasher is less than or equal to the second preset humidity, if the heating element is in the on state, the heating element is controlled to stop working. If the fan is in the on state, the fan is controlled to stop working. Optionally, in the process of controlling the fan to stop working, the controller can control the fan to run continuously for a certain period of time and then turn off the fan.

[0081] The washing control method for a dishwasher provided in the present application can control the heating element inside the dishwasher to heat. The controller can also control the washing pump in the dishwasher to spray washing liquid. The washing liquid sprayed from the washing pump can be vaporized when it contacts the heating element to form vaporized washing liquid. When the controller determines that the dishwasher meets the preset conditions, the heating element can be controlled to stop working, and the dishwasher can be controlled to perform subsequent washing tasks. In the present application, by adding a heating element, the washing liquid can be vaporized when it contacts the heating element, steam washing is achieved, and the cleaning effect of the dishwasher is improved. In addition, in the present application, by adjusting the rotation speed of the washing pump according to the cooling time of the heating element, the vaporization efficiency of the washing liquid is improved, and the cleaning effect of the dishwasher is further improved; in addition, in the present application, the drying efficiency of the dishwasher is improved by using the heating element and the fan in the drying stage.

[0082] On the basis of the above embodiment, the controller can also control the dishwasher to control the washing heating pump in the dishwasher to heat the washing liquid in the dishwasher before starting washing, until the temperature of the washing liquid in the dishwasher reaches a third preset temperature. The third preset temperature is lower than the second preset temperature. This heating operation can make the washing liquid contact the heating element at a higher temperature, reduce the heat absorbed by the washing liquid during the vaporization process, and thus improve the vaporization efficiency. Optionally, the third preset temperature is a temperature less than or equal to the boiling point of the washing liquid. For example, the third preset temperature can be 70 degrees, 80 degrees, 90 degrees, etc.

[0083] Based on the above embodiment, the controller determines whether the dishwasher meets the preset conditions and executes the following process: Figure 3 and Figure 4 shown.

[0084] First, the controller can initialize the k value and set k=0. The k value is used to indicate the number of times the heating element is heated. Alternatively, the controller can initialize the t value and set t=0. The t value is used to record the total heating time of the heating element.

[0085] A temperature sensor is provided in the dishwasher. When the dishwasher uses a washing heat pump to heat the washing liquid, the temperature sensor can detect the temperature of the washing liquid in real time. When it is detected that the temperature of the washing liquid reaches a third preset temperature, the washing heat pump stops working. Optionally, during the washing process, if the temperature sensor detects that the temperature of the washing liquid is lower than a fourth preset temperature, the controller can start the washing heat pump again to heat the washing liquid so that the temperature of the washing liquid reaches the third preset temperature. Optionally, the fourth preset temperature is lower than the third preset temperature.

[0086] The dishwasher can control the heating element to turn on and make the heating element self-heating. At this time, the temperature of the heating element rises. A temperature sensor can be provided in the heating element. The temperature sensor continuously detects the temperature of the heating element. If it is detected that the temperature of the heating element reaches the first preset temperature, it means that the temperature of the heating element is high. At this time, the controller can control the washing pump to start and enter the continuous washing link. During the washing process of the washing link, when the washing liquid contacts the heating element, the washing liquid is vaporized and converted into water vapor. In this process, the heating element absorbs heat and the temperature decreases. When the temperature of the heating element is lower than the second preset temperature, the washing pump stops working. At this time, the controller determines whether the number of heating times k of the heating element is less than n, or whether the heating time t is less than t0. If so, the heating element restarts. The controller can start the washing pump again when the heating element is heated to the first preset temperature to realize the cyclic start between the heating element and the washing pump. If the number of heating times k of the heating element is greater than or equal to n, or the heating time t is greater than or equal to t0, the controller can turn off the washing pump and the heating element and perform subsequent washing tasks.

[0087] Optionally, in the subsequent washing task, the controller can start the fan to accelerate the air circulation inside the dishwasher, so that more vaporized washing liquid can be combined with the pollutants to improve the washing efficiency of stubborn pollutants in the subsequent washing process. The controller can stop the fan operation after the fan is maintained for a period of time t1, and start the washing pump to rinse the dishes.

[0088] Based on the above embodiment, the process of the controller adjusting the speed of the washing pump can be as follows: Figure 5 As shown. The controller can initialize the k value and set k=0. The k value is used to indicate the cooling time of the heating element. Alternatively, the controller can initialize the t value and set t=0. The t value is used to record the total heating time of the heating element. When the dishwasher is started, the speed of the washing pump can be the set speed of the dishwasher.

[0089] A temperature sensor is provided inside the dishwasher. When the dishwasher uses the washing heating pump to heat the washing liquid, this temperature sensor can detect the temperature of the washing liquid in real time. When it is detected that the temperature of the washing liquid reaches the third preset temperature, the washing heating pump stops working. The total heating duration t starts to be timed.

[0090] Among them, a first preset duration k0, a second preset duration k1, and a total preset duration t0 can be set in the controller. The first preset duration k0 is less than the second preset duration k1. When k0 < k < k1, it indicates that the liquid volume of the washing liquid in contact with the heating element matches the supply temperature of the heating element, and the optimal vaporization of the washing liquid can be achieved. When k < k0, it indicates that the liquid volume of the washing liquid sprayed by the washing pump is large and the supply temperature of the heating element is insufficient. When k > k1, it indicates that the liquid volume of the washing liquid sprayed by the washing pump is small and the supply temperature of the heating element is excessive. The total preset duration t0 is the preset total heating duration of the heating element during the heating stage of the heating element.

[0091] The dishwasher can control the heating element to turn on and enable the heating element to self-heat. At this time, the temperature of the heating element rises. A temperature sensor can be provided in the heating element. This temperature sensor continuously detects the temperature of the heating element. If it is detected that the temperature of the heating element reaches the first preset temperature, it indicates that the temperature of the heating element is relatively high. At this time, the controller can control the washing pump to start and enter the continuous washing link. At the same time when the washing pump starts, the cooling duration k starts to be timed. During the washing process of the washing link, when the washing liquid comes into contact with the heating element, the washing liquid is vaporized and converted into water vapor. During this process, the heating element absorbs heat and the temperature decreases. When the temperature of the heating element is lower than the second preset temperature, or when the cooling duration k is greater than the second preset duration k1, the controller can continue to judge whether the total heating duration t is greater than the total preset duration t0.

[0092] If t < t0 and k < k0, it indicates that the previous trigger condition is that the temperature of the heating element is lower than the second preset temperature. At this time, k < k0 indicates that the temperature of the heating element drops relatively fast. That is, the liquid volume of the washing liquid sprinkled on the heating element per unit time is large, the rotation speed of the washing pump is fast, and the heat generated by the heating element is not enough to fully evaporate the washing liquid. At this time, the controller can slow down the rotation speed of the washing pump so that r = r - r0. Where r is the rotation speed of the washing pump after the previous adjustment. At the same time, the controller can also control the washing pump to stop working. The controller can clear the cooling duration k to zero. The controller can control the heating element to heat and enter the next cycle when the temperature of the heating element is greater than or equal to the first preset temperature.

[0093] If t < t0 and k0 < k < k1, it indicates that the previous triggering condition is that the temperature of the heating element is lower than the second preset temperature. At this time, the temperature of the heating element drops to the second preset temperature, but the dropping rate is appropriate. At this time, the controller can control the washing pump to stop working. The controller can clear the cooling duration k to zero. The controller can control the heating element to heat up, and enter the next cycle when the temperature of the heating element is greater than or equal to the first preset temperature.

[0094] If t < t0 and k > k1, it indicates that the previous triggering condition is k > k1. At this time, the temperature of the heating element usually does not drop to the second preset temperature. The temperature of the heating element can not only satisfy the vaporization of the liquid volume of the washing liquid ejected by the current washing pump, but also there is a surplus of heat. Therefore, the controller can appropriately increase the liquid volume of the washing liquid ejected by the washing pump. The controller can increase the rotation speed of the washing pump so that r = r + r0. Where r is the rotation speed of the washing pump after the previous adjustment. At this time, the controller can not end the execution of the washing pump within this cycle. The controller can clear the cooling duration k to zero. The controller can continue to judge whether the temperature of the heating element is lower than the second preset temperature, or whether the cooling duration k is greater than the second preset duration k1 is satisfied.

[0095] If t ≥ t0, the controller can turn off the washing pump and the heating element, and perform subsequent washing tasks.

[0096] Optionally, during the execution of the subsequent washing tasks, the controller can start the blower to accelerate the air circulation inside the dishwasher, so that more vaporized washing liquid combines with the pollutants, thereby improving the washing efficiency of stubborn pollutants during the subsequent flushing process. The controller can stop the blower operation after the blower maintains for a duration of t1, and turn on the washing pump to wash the tableware.
