[0032] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0033] With the improvement of social science and technology, more and more kitchen appliances are used in life, which has brought great convenience to people's living standards. Among them, the use of dishwashers has greatly improved the cleaning efficiency of tableware. At present, the washing program of a dishwasher can usually include two stages: washing and drying. Among them, the washing stage can be further divided into four parts: pre-washing, main washing, cold rinsing, and hot rinsing. In the hot rinsing stage of the washing program, the water is heated by an electric heating tube, and then the tableware is rinsed with hot water to achieve the purpose of heating the tableware. In the drying stage, the controller can realize the drying of the tableware in the dishwasher by controlling the drying module. At present, the drying module can usually include two parts: a heating tube and a fan. The "high temperature and high humidity" inner cavity air environment generated by the execution of the hot rinsing + drying program of the washing program is not conducive to the drying of the tableware, and causes the inner cavity moisture to overflow on the door lining and the surface of the cabinet to form condensed water, and even drip onto the ground. It can be seen that the existing technology has the problem of low drying efficiency.

[0034] In order to solve this problem, the drying control method proposed in this application combines the automatic door opening and closing actuator set on the dishwasher, so that the dishwasher can open the door to discharge water vapor when the humidity is high, thereby reducing the humidity in the inner cavity of the dishwasher and improving the drying effect. Specifically, this application combines the control method of the three technologies of hot bleaching without heating in the washing program + independent drying module + automatic door opening and closing actuator, realizing a high temperature + low humidity inner cavity air environment, improving the drying effect, reducing the overflow of moisture in the inner cavity to form condensed water droplets, and at the same time realizing precise temperature control of tableware. In addition, this application sets dual independent axial flow fans in the drying module, and through forward and reverse rotation, four air ducts are formed in the inner cavity to improve the drying performance.

[0035] In order to realize the function of this application, the dishwasher used in this application can be as follows Figures 1 to 3 As shown. Figure 1 As shown, the dishwasher 100 may include an inner cavity 110. The inner cavity 110 may include a top wall, a side wall and a bottom wall. Among them, with reference to the dishwasher door body, the side wall can be divided into a left wall, a right wall and a rear wall. The drying module 120 is installed in the middle of the rear wall of the inner cavity 110 of the dishwasher. Optionally, the drying module 120 can be a dual independent drying module. That is, two independent drying modules 120 can be respectively arranged on both sides of the inner water pipe 140. The middle of the circular area of ​​the drying module 120 is the first air outlet 121, and the three strip air outlets on the upper and lower sides of the circle and away from the inner water pipe 140 are the second air outlets 122. A rectangular cover plate is arranged on the drying module 120. The first air outlet 121 and the second air outlet 122 are arranged on the rectangular cover plate. The automatic door opening and closing actuator 130 is installed in the middle of the top of the U-shaped column of the dishwasher 100. As shown Figure 2As shown, behind the cover plate of the drying module 120, a fan 123, blades 124 and a heating pipe 125 may be included. Among them, the fan 123 may be an axial flow fan. The heating pipe 125 is circular and surrounds the blades 124. When the fan 123 rotates, it drives the blades 124 to rotate, and blows the heat generated by the heating pipe 125 into the inner cavity 110, so that the inner cavity 110 reaches a higher temperature, which has the effect of drying and drying. Optionally, when the fan 123 is in forward transmission, the first air outlet 121 is the air inlet and the second air outlet 122 is the air outlet. When the fan 123 is reversed, the second air outlet 122 is the air inlet and the first air outlet 121 is the air outlet.

[0036] Optionally, a plurality of sensors 150 may be disposed inside the inner cavity 110. Optionally, the plurality of sensors 150 may be a plurality of sensors disposed at different positions. Optionally, the plurality of sensors 150 may be sensors with multiple functions. For example, Figure 3 As shown, the sensor 150 disposed on the inner water pipe 140 may be a wind speed and direction sensor. For another example, the sensor 150 disposed on the left side wall of the inner cavity 110 may be a temperature sensor and / or a humidity sensor.

[0037] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0038] Figure 4 Schematic diagram of the drying control method provided in this application Figure 1 ,like Figure 4 As shown, in Figures 1 to 3 Based on the illustrated embodiment, the controller of the dishwasher is used as the execution subject, and the method includes:

[0039] S201. Determine a drying time in a drying phase of the dishwasher according to parameter information of the dishwasher in a main wash phase and a target temperature of tableware preset in the dishwasher.

[0040] In this embodiment, after the main wash stage of the dishwasher is finished, the controller can obtain parameter information of the main wash stage. Optionally, the parameter information may include total energy consumption, energy consumption generated by heating water, initial water temperature, final water temperature, washing time, initial tableware temperature, final tableware temperature, etc. In addition, the controller may also preset a target temperature for the tableware. The target temperature is the temperature that the tableware needs to reach when drying is finished. The controller can calculate the drying time that the dishwasher needs to perform in the drying stage based on the parameter information of the main wash stage and the target temperature of the tableware, thereby ensuring that the tableware achieves a preset drying effect at the end of drying and that the tableware reaches the target temperature.

[0041] S202: Generate and execute a drying program of the drying stage of the dishwasher according to the drying time.

[0042] In this embodiment, after determining the drying time, the controller generates a corresponding drying program. The generation of the drying program may specifically include setting the drying temperature, setting the fan rotation direction, setting the fan rotation speed, and setting the heating power of the heating tube. After completing the setting of the drying program, the controller may start the drying program and enter the drying stage. The controller may execute the generated drying program step by step to ensure that the moisture on the surface of the tableware is effectively removed within the set time and the temperature of the tableware is controlled.

[0043] S203. During the execution of the drying program, if the real-time environmental value of the inner cavity of the dishwasher is greater than or equal to a first threshold, the dishwasher is controlled to automatically open its door according to the real-time environmental value; until the detected real-time environmental value is less than the first threshold, the dishwasher is controlled to close its door.

[0044] In this embodiment, during the execution of the drying program, the controller can continuously monitor the real-time environmental value of the inner cavity of the dishwasher. Optionally, the real-time environmental value can be temperature and / or humidity. When it is detected that the real-time environmental value is greater than or equal to a preset first threshold, the controller can automatically trigger the door opening mechanism of the dishwasher, and control the dishwasher door to open through the automatic door opening and closing actuator to promote air circulation and moisture discharge. When it is detected that the real-time environmental value is less than the first threshold, the controller can automatically trigger the door closing mechanism of the dishwasher, and control the dishwasher door to close through the automatic door opening and closing actuator to maintain drying efficiency and energy saving effects. This dynamic adjustment process ensures optimal performance in the drying stage and an ideal drying state for the tableware.

[0045] For example, when the real-time environmental value is the humidity of the inner cavity, the controller can monitor the humidity of the inner cavity in real time during the drying stage through a humidity sensor disposed in the inner cavity. During the drying stage, the humidity of the inner cavity shows a downward trend. When the controller determines at the beginning of the drying stage that the humidity of the inner cavity of the dishwasher is greater than or equal to the first threshold, the specific execution process of the controller controlling the dishwasher to open the door may include the following steps:

[0046] Step 1: Determine the door opening of the dishwasher according to the inner cavity humidity and a first mapping table. The first mapping table represents the mapping relationship between the inner cavity humidity and the door opening of the dishwasher.

[0047] In this embodiment, a first mapping table may be stored in the controller. The first mapping table defines the relationship between different inner cavity humidity and door opening. By searching the first mapping table, the controller can convert the currently detected inner cavity humidity into an appropriate door opening, thereby automatically adjusting the degree of opening of the door to optimize moisture discharge and drying effect. In this way, the controller can dynamically adjust the door opening to ensure that the dishwasher can achieve optimal drying performance under different humidity conditions.

[0048] Step 2: Control the dishwasher to open the door automatically according to the door opening degree.

[0049] In this embodiment, after determining the door opening, the controller can drive the automatic door opening actuator of the dishwasher according to the door opening to accurately control the door position of the dishwasher. This process ensures that the mapping relationship between the door opening and the inner cavity humidity is accurately executed, thereby optimizing the drying effect and energy efficiency. Optionally, the controller can also continuously monitor the inner cavity temperature and periodically adjust the door opening of the dishwasher according to the inner cavity humidity to adapt to changes in the inner cavity of the dishwasher.

[0050] The drying control method provided in the embodiment of the present application is such that after the main wash stage of the dishwasher is finished, the controller can obtain the parameter information of the main wash stage. After determining the drying time, the controller generates a corresponding drying program. The controller can start the drying program and enter the drying stage. During the execution of the drying program, the controller can continuously monitor the real-time environmental value of the inner cavity of the dishwasher. When it is detected that the real-time environmental value is greater than or equal to a preset first threshold, the controller can control the dishwasher to open the door. When it is detected that the real-time environmental value is less than the first threshold, the controller can control the dishwasher to close the door. The present application optimizes the moisture discharge in the drying stage and improves the drying effect by continuously monitoring the real-time environmental value of the inner cavity of the dishwasher and dynamically controlling the opening and closing of the dishwasher door according to the preset first threshold.

[0051] Figure 5 Schematic diagram of the drying control method provided in this application Figure 2 ,like Figure 5 As shown, in this embodiment Figures 1 to 4 Based on the embodiment, the calculation process of the drying time in the drying stage of the dishwasher is described in detail. The method includes:

[0052] S301. Calculate an estimated energy consumption in a drying stage according to parameter information in a main wash stage and a first temperature change value determined based on a target temperature of the dishes.

[0053] In this embodiment, during the operation of the dishwasher, the controller may record parameter information of the main wash stage. Optionally, these parameter information may include total energy consumption, energy consumption generated by heating water, initial water temperature, final water temperature, washing time, initial tableware temperature, final tableware temperature, etc. The controller may also obtain a preset target temperature of the tableware. The target temperature of the tableware is the temperature of the tableware that the user can directly pick up. The controller may determine the first temperature change value based on the target temperature. The first temperature change value indicates the temperature value that the tableware needs to be adjusted to in the drying stage after completing the main wash stage.

[0054] Optionally, the first temperature change value can be determined based on the end temperature of the tableware at the end of the main wash stage and the target temperature of the tableware. For example, after the main wash stage is completed, the end temperature of the tableware can be 30 degrees. The target temperature can be 40 degrees. The controller determines that the first temperature change value is 10 degrees based on the difference between the target temperature and the end temperature.

[0055] Optionally, the end temperature of the tableware can be obtained according to laboratory measurements. Alternatively, the end temperature of the tableware can be measured at the end of the main wash stage. Optionally, at the end of the main wash stage, the controller can measure the end temperature of the tableware through a temperature sensor disposed on the inner wall of the inner cavity.

[0056] The controller can estimate the estimated energy consumption required for the tableware to achieve the change of the first temperature change value during the drying stage based on the energy consumption stored in the parameter information of the main wash stage.

[0057] In one example, the specific process of the controller calculating the estimated energy consumption in the drying stage may include:

[0058] Step 1: Calculate other energy consumption in the main wash stage according to the difference between the total energy consumption in the parameter information of the main wash stage and the first energy consumption generated by heating water.

[0059] In this embodiment, the energy consumption in the main wash stage mainly includes the energy consumption generated by heating water, the energy consumption generated by heating tableware, and the energy consumption generated by other interference factors. The controller can first obtain the total energy consumption from the parameter information of the main wash stage. Secondly, the controller can obtain the first energy consumption generated by heating water. The controller determines the other energy consumption in the main wash stage according to the difference between the total energy consumption and the first energy consumption. The other energy consumption may include the energy consumption generated by heating tableware and the energy consumption generated by other interference factors.

[0060] Step 2: Calculate the first parameter based on the ratio of other energy consumption and the second temperature change value of water in the parameter information of the main wash stage.

[0061] In this embodiment, after obtaining the parameter information of the main wash stage, the controller can also obtain a second temperature change value of the water from the parameter information. The second temperature change value can be the temperature at which the water temperature is raised by heating in the main wash stage. The controller can use other energy consumption divided by the second temperature change value of the water to obtain the first parameter.

[0062] Step 3: Calculate the estimated energy consumption in the drying stage according to the product of the first temperature change value and the first parameter.

[0063] In this embodiment, the controller can use the product of the first temperature change value of the tableware and the first parameter as the estimated energy consumption. The estimated energy consumption is the estimated energy consumption obtained by analogy based on the impact of other energy consumption on water temperature in the main wash stage except for heating water, according to the temperature change of the tableware.

[0064] Optionally, in this example, based on the impact of other energy consumption in the main wash stage on the water temperature, the energy consumption required for the temperature change of the tableware in the drying stage is estimated, and the estimated energy consumption is automatically calculated to ensure the accuracy and timeliness of the calculation.

[0065] S302: Calculate the drying time of the dishwasher in the drying stage according to the estimated energy consumption in the drying stage and the parameter information of the main washing stage.

[0066] In this embodiment, after calculating the estimated energy consumption of the drying stage, the controller can further calculate the drying time of the drying stage of the dishwasher based on the estimated energy consumption and the parameter information of the main wash stage. Specifically, the controller can determine the energy consumption per unit time based on the parameter information of the main wash stage, and then determine the required drying time based on the estimated energy consumption. Optionally, when the dishwasher completes the drying time, the tableware can reach the target temperature.

[0067] In one example, the specific process of the controller calculating the drying time of the drying stage of the dishwasher may include:

[0068] Step 1: Calculate the second parameter based on the ratio of the estimated energy consumption to other energy consumption.

[0069] In this embodiment, after obtaining the estimated energy consumption and other energy consumption, the controller may calculate the ratio of the estimated energy consumption and other energy consumption to obtain the second parameter.

[0070] Step 2: Calculate the drying time based on the product of the second parameter and the heating time in the parameter information of the main wash stage.

[0071] In this embodiment, the controller may obtain the heating time in the parameter information of the main wash stage. Further, the controller may calculate the product of the second parameter and the heating time to calculate the drying time.

[0072] Optionally, in this example, the drying time required when the estimated energy consumption is consumed in the drying stage is obtained by analogy based on the ratio of other energy consumption and heating time. This calculation process realizes the automatic calculation of the drying time, improving the accuracy and timeliness of the results.

[0073] In one example, the method further includes:

[0074] Step 3: Determine the compensated drying time according to the sum of the time compensation value and the drying time, wherein the time compensation value is determined according to the heat transfer rate of air and the heat transfer rate of water.

[0075] In this embodiment, in order to further improve the accuracy of the drying time, after calculating the drying time according to step 2, this example further uses the time compensation value to compensate the drying time to obtain the compensated drying time. Specifically, the controller can use the sum of the drying time calculated in step 2 and the time compensation value to determine the compensated drying time.

[0076] Optionally, the time compensation value can be determined based on the heat transfer rate of air and water. The use of the time compensation value further increases the characteristics of environmental conditions and equipment characteristics, improves the effectiveness of the drying time, and optimizes the overall performance.

[0077] In the drying control method provided in the embodiment of the present application, the controller can estimate the estimated energy consumption required for the tableware to achieve the change of the first temperature change value in the drying stage according to the energy consumption stored in the parameter information of the main wash stage. The controller can further calculate the drying time of the dishwasher in the drying stage based on the estimated energy consumption and the parameter information of the main wash stage. The present application realizes the estimation of the drying time by analyzing the energy consumption stored in the parameter information of the main wash stage, improves the calculation accuracy of the drying time, and improves the washing effect.

[0078] In the above Figures 1 to 5 Based on the embodiment shown, the dishwasher includes a drying module, and at least one fan is provided in the drying module. The process of the controller controlling the fan may include:

[0079] S401. During the execution of the drying program, the fan rotation direction and speed of the dishwasher are adjusted according to the real-time environmental value of the inner cavity of the dishwasher.

[0080] In this embodiment, during the execution of the drying program, the controller can continuously monitor the real-time environmental value of the inner cavity of the dishwasher. Optionally, the real-time environmental value may include temperature and / or humidity. The controller can dynamically adjust the rotation direction and speed of the fan according to the real-time environmental value. Optionally, the present application can optimize the air flow by dynamically adjusting the rotation direction and speed of the fan, thereby better evenly distributing heat and promoting the discharge of water vapor from the inner cavity.

[0081] In one example, the specific process of the controller adjusting the fan speed of the dishwasher may include:

[0082] Step 1: If the real-time environment value is less than the second threshold, the speed of the fan is reduced according to the difference between the real-time environment value and the first threshold.

[0083] Step 2: If the real-time environment value is greater than the second threshold, the speed of the fan is increased according to the difference between the real-time environment value and the first threshold.

[0084] In this embodiment, during the execution of the drying program, the controller can obtain the real-time environmental value of the inner cavity of the dishwasher and then compare the real-time environmental value with a preset second threshold. Optionally, if the real-time environmental value is less than the second threshold, it means that the real-time environmental value is closer to the expected value. At this time, the controller can reduce the speed of the fan to achieve energy saving. If the real-time environmental value is greater than the second threshold, it means that the real-time environmental value is far from the expected value. At this time, the controller can increase the speed of the fan to facilitate the adjustment of the real-time environmental value.

[0085] For example, when the real-time environmental value is humidity, the controller may adjust the fan speed downward when the humidity is less than the second threshold, and the controller may adjust the fan speed upward when the humidity is greater than the second threshold.

[0086] In one example, a plurality of sensors may be provided in the inner cavity of the dishwasher. The plurality of sensors are provided on at least one of the top wall, the side wall and the bottom wall of the inner cavity. The plurality of sensors are evenly distributed inside the inner cavity. Based on the plurality of sensors, the specific process of the controller adjusting the rotation direction of the fan of the dishwasher may include:

[0087] Step 1: Calculate the difference between the real-time environment value of each sensor and the second threshold value, and determine the position of the sensor corresponding to the largest difference as the target position.

[0088] Step 2: Determine the rotation direction of each fan according to the target position and the second mapping table. The second mapping table represents the correspondence between the rotation direction of the fan and the position affected by the air flow inside the inner cavity.

[0089] In this embodiment, during the execution of the drying program, the controller can obtain real-time environmental values ​​from each sensor. The controller can calculate the difference between the real-time environmental value of each sensor and the second threshold value. The larger the difference, the more it indicates that the real-time environmental value of the area needs fan-assisted processing. Therefore, the controller can obtain the sensor with the largest difference by comparing the multiple differences. The controller can determine the location of the sensor as the target location. Then, the controller can refer to the second mapping table according to the target location. The second mapping table indicates the correspondence between the direction of rotation of the fan and the position affected by the flow of air inside the inner cavity. Through the second mapping table, the controller can determine the direction of rotation that the fan needs to execute when the air inside the inner cavity needs to affect the position of the sensor with the largest difference during the flow. Optionally, when the drying module includes multiple fans, the rotation direction can specifically be the rotation direction of each fan in the drying module. Optionally, the adjustment of the rotation direction of the fan can optimize the air flow in the inner cavity, thereby ensuring the uniformity and efficiency of the drying effect.

[0090] In one example, a wind speed sensor may also be provided in the dishwasher. Optionally, the wind speed sensor may be an ultrasonic wind speed sensor. Optionally, the controller may obtain the actual wind speed through the wind speed sensor. The controller may compare the actual wind speed with the preset wind speed. If the actual wind speed is less than the preset wind speed, the controller may control the fan to increase the wind speed, thereby ensuring that the wind speed reaches the expected value and achieves a better drying effect. Otherwise, if the actual wind speed is greater than the preset wind speed, the controller may control the fan to reduce the wind speed, thereby ensuring that the wind speed reaches the expected value.

[0091] Figure 6 Schematic diagram of the drying control method provided in this application Figure 3 ,like Figure 6 As shown, in this embodiment Figures 1 to 5 Based on the embodiment, a schematic diagram of the execution process of a dishwasher is taken as an example, and the method includes:

[0092] S501, the washing program starts running, and the washing program is controlled not to perform heating in the thermal bleaching stage.

[0093] In this embodiment, when the cold rinsing stage of the washing program is completed, the washing stage is basically completed. In the prior art, the hot rinsing stage of the washing program mainly has two functions: adding one rinse and heating the tableware to a certain temperature through the washing water. Based on the tableware heated in the hot rinsing stage, the water on the surface of the tableware can be evaporated more quickly in the drying stage to achieve the drying of the tableware. The present application changes "hot rinsing" into "cold rinsing" and no longer heats the hot rinsing. The operation of changing "hot rinsing" into "cold rinsing" can save energy consumption for heating tableware and washing water.

[0094] S502, automatically calculate the drying time of the drying stage. The controller can obtain the water consumption w of the main wash stage, the energy consumption Q generated by heating in the main wash stage, the heating time t, and the water temperature rise k in the main wash heating stage. The controller can also obtain the power consumption Q1 consumed by the water consumption w. Furthermore, the controller can calculate the power consumption Q2 required for heating the drying module in the drying stage by the formula (Q-Q1) / k*k1. Among them, k1 is the first temperature change of the tableware in the drying stage. Optionally, the first temperature change can be in the range of 5 degrees to 15 degrees. Preferably, the first temperature change can be 10 degrees. Furthermore, the controller can calculate the drying time t1 of the drying stage by the formula Q2 / (Q-Q1)*t. Since there is a large difference in the heat transfer rate between air and water, the controller can further compensate t1 appropriately. Optionally, the time compensation value of the compensation can be 10 minutes.

[0095] S503, the drying module works to heat the air. The controller can heat the air in the inner cavity through the operation of the drying module, thereby achieving the purpose of heating the tableware.

[0096] S504: The controller may obtain the humidity of the inner cavity and determine whether the humidity is greater than or equal to a first threshold. If the humidity is greater than or equal to the first threshold, S505 is executed. If the humidity is less than the first threshold, S506 is executed.

[0097] S505: If the humidity is greater than or equal to the first threshold, the controller can control the dishwasher to open the door to a certain angle through the automatic door opening and closing actuator, so that the water vapor in the inner cavity is discharged into the external environment. After the dishwasher opens the door, the controller can control the axial flow fan in the drying module to realize the alternating operation of the four air ducts, thereby better assisting the inner cavity to discharge water vapor. The controller returns to S504.

[0098] S506: If the humidity is less than the first threshold, the controller can control the dishwasher to close the door through the automatic door opening and closing actuator. After closing the door, the controller can keep the door closed and execute the drying program until the drying is completed.
