Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent household appliance control, and particularly relates to a liner temperature correction method, a dishwashing machine operation control method and related systems. BACKGROUND

[0002] In intelligent household appliances, to accurately detect the temperature of the inner container, the commonly used method is to embed a temperature sensor. For example, a thermocouple or a thermistor is used to collect the temperature of the inner container. A thermocouple is a temperature sensor based on the thermoelectric effect. It is composed of two wires of different metals. When the temperature at both ends is different, an electric potential difference will be generated, thereby converting the temperature signal into an electric signal. This method has been widely used in intelligent household appliances, especially in scenarios that require high-precision temperature detection. The resistance value of a thermistor changes with temperature. By measuring the change in resistance value, the current temperature can be calculated. This method has a lower cost, so it is also widely used in some economic intelligent household appliances.

[0003] These methods are widely used in various intelligent household appliances, such as electric rice cookers, electric water heaters, and smart refrigerators. In these devices, accurate temperature detection is crucial for ensuring normal operation, improving energy efficiency, and ensuring user safety.

[0004] However, in intelligent household devices such as electric rice cookers and dishwashers, fluctuations in water temperature often interfere with the collection of air temperature, which may cause errors. Such errors not only affect the accurate performance of the device, but also may pose potential safety risks.

[0005] Specifically, when these devices are in operation, the water in the inner container is heated, producing a large amount of water vapor. This water vapor mixes with the air inside the device, causing rapid changes in local air temperature. If the temperature sensor happens to be located in this area of change, its readings may be significantly affected. For example, in an electric rice cooker, when the rice begins to boil, a large amount of water vapor is released, which may cause the temperature sensor to misread the environment temperature as rising, thereby misleading the control system. Similarly, in a dishwasher, the circulation of hot water and the generation of steam can also cause similar interference to the temperature sensor.

[0006] The Chinese patent "A dishwasher and a control method thereof", published on August 15, 2023, with publication number CN 116584857A, specifically discloses a first temperature sensor installed in the washing cavity, electrically connected with the controller, for detecting a first temperature parameter in the washing cavity; and a second temperature sensor installed outside the washing cavity, electrically connected with the controller, for detecting a second temperature parameter of the air flowing through the drying heater. This scheme directly uses the collected temperature of the temperature sensor as the actual temperature, which is easy to cause actual control deviation.

[0007] The Chinese patent "Condenser, dishwasher and control method of dishwasher", published on March 12, 2024, with publication number CN 117678948A, specifically discloses a condenser, a dishwasher and a control method of the dishwasher. The condenser includes a condensing air duct, an air cooling module arranged on one side of the condensing air duct, a water cooling module arranged on the other side of the condensing air duct, a water supply system connected with the water cooling module, a temperature detection module adapted to detect the ambient temperature in the condensing air duct and send a temperature signal, and a controller communicatively connected with the temperature detection module and the water supply system. The controller controls the water supply system to supply water to the water cooling module according to the temperature signal sent by the temperature detection module, so as to cool the condensing air duct by the water cooling module, or start the air cooling module to cool the condensing air duct by the air cooling module. Similarly, this scheme directly uses the temperature signal sent by the temperature detection module to execute control, which is easy to cause actual control deviation. SUMMARY

[0008] The present application aims to solve the problem that the temperature data collected by the temperature sensor in the prior art is directly used as the inner container temperature, which is easily affected by the water temperature and inaccurate. The present application provides an inner container temperature correction method, a dishwasher operation control method and related systems. The inner container temperature correction method corrects the temperature collected by the inner container sensor in the intelligent household appliance to avoid the influence of water temperature and other factors on the actual inner container temperature. At the same time, the preset conditions are used to control the full opening and partial opening of the refrigeration device load under different temperature conditions and different demand cooling time conditions, so as to improve the user experience while reducing the opening time of the load and saving electricity.

The actual temperature value of the current inner container is calculated by using the first influence data set and the difference between the actual temperature value and the inner container sensor, so as to correct the sensor collection error caused by the position of the inner container sensor or the humidity in the inner container and other factors, and improve the accuracy of the inner container temperature output.

[0012] Another technical solution provided by the application is a dish washing machine operation control method, which uses the above-mentioned inner container temperature correction method to realize the operation control of the dish washing machine, comprising the following steps: obtaining a current inner container temperature by using the inner container temperature correction method, and performing a corresponding control action according to the current inner container temperature and a preset condition.

[0013] Further, the preset condition at least comprises a first temperature threshold and a second temperature threshold; and the performing of the corresponding control action according to the current inner container temperature and the preset condition further comprises: performing an opening door action if the current inner container temperature is less than the first temperature threshold; controlling a part of loads to perform a cooling action if the current inner container temperature is greater than the first temperature threshold and less than the second temperature threshold; and controlling all loads to perform the cooling action if the current inner container temperature is greater than the second temperature threshold.

[0014] Further, the preset condition at least includes a required cooling time, a first temperature threshold, a first cooling amplitude range and a second cooling amplitude range; and the performing the corresponding control action according to the current inner container temperature and the preset condition further includes: calculating a required cooling amplitude according to the current inner container temperature, the required cooling time and the first temperature threshold; if the current inner container temperature is less than or equal to the first temperature threshold, performing an opening action; and if the current inner container temperature is greater than the first temperature threshold, controlling part of the loads to perform a cooling action when the required cooling amplitude is in the first cooling amplitude range, and controlling all the loads to perform the cooling action when the required cooling amplitude is in the second cooling amplitude range.

[0015] Further, the performing the corresponding control action according to the current inner container temperature and the preset condition further includes: if the current inner container temperature is greater than the first temperature threshold and less than a second temperature threshold, controlling part of the loads to perform the cooling action; and after a first preset execution time is reached, judging whether the inner container temperature is less than or equal to the first temperature threshold, and if not, controlling all the loads to perform the cooling action.

[0016] Further, the first cooling amplitude range is constructed according to the inner container temperature cooling condition when part of the loads perform the cooling action, and the second cooling amplitude range is constructed according to the inner container temperature cooling condition when all the loads perform the cooling action.

[0019] The beneficial effects of the present application are: the collected data of the inner container sensor are taken as the first influence data set, and the difference between the actual temperature value and the inner container sensor is obtained based on the inner container temperature influence relationship, and the actual temperature of the current inner container is calculated based on the first influence data set and the difference between the actual temperature value and the inner container sensor, so as to correct the sensor collection error caused by the position of the inner container sensor or the humidity in the inner container and other factors, and improve the accuracy of the output of the inner container temperature. By whether the current inner container temperature exceeds the second temperature threshold, the partial load refrigeration and full load refrigeration of the refrigeration device are respectively executed, which can reduce the working load to reduce energy consumption when the temperature is low, and can accelerate the cooling speed through full load refrigeration at full speed when the temperature is high, which can also achieve the effect of reducing energy consumption.

[0024] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only the best embodiment of the present application, which are used to explain the present application and do not limit the protection scope of the present application. All other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0025] As shown in Figure 1 The inner container temperature correction method comprises the following steps: collecting data of the inner container sensor as the first influence data set, calculating the inner container temperature change rate based on the first influence data set based on the inner container temperature influence relationship, and correcting the current inner container temperature based on the inner container temperature change rate.

[0026] In the embodiment, the collection data of the liner sensor is taken as the first influence data set, and the difference between the actual temperature value and the liner sensor is obtained based on the liner temperature influence relationship, and the actual temperature of the current liner is calculated based on the first influence data set and the difference between the actual temperature value and the liner sensor, so as to correct the sensor collection error caused by the position of the liner sensor or the humidity in the liner and other factors, and improve the accuracy of the liner temperature output.

[0027] The liner temperature correction method further comprises: The historical liner actual temperature data and the historical liner sensor collection data are obtained, and the liner temperature influence relationship is constructed based on the historical liner actual temperature data and the historical liner sensor collection data.

[0028] The historical liner actual temperature data and the historical liner sensor collection data can be obtained through laboratory data or through the historical use data of the intelligent household appliance. The liner sensor collection data at least includes the liner water temperature, and the historical liner sensor collection data at least includes the historical liner water temperature, so that the correlation between the liner water temperature and the liner actual temperature is obtained based on the correlation analysis of the historical liner actual temperature data and the historical liner water temperature, and the correlation curve is taken as the liner temperature influence relationship. At this time, the first influence data set at least includes the current liner water temperature and the liner initial parameter, and the liner temperature change rate corresponding to the current liner water temperature is obtained based on the current liner water temperature and the correlation curve between the liner water temperature and the liner actual temperature. At this time, the liner temperature change rate is the ratio of the liner water temperature to the liner actual temperature. The current liner temperature of the liner actual temperature correction output is obtained based on the current liner water temperature and the liner temperature change rate, the collection error of the liner sensor is compensated, the problem of inaccurate temperature monitoring caused by the position of the liner sensor or the heat transfer ratio is avoided, the accuracy of the liner temperature output is improved, and the accuracy of the control affected by the liner temperature in the intelligent household appliance is improved.

[0029] As the second embodiment of the present application, considering that the correlation curve between the liner water temperature and the liner actual temperature is a nonlinear curve, the temperature influence in different situations can also be different, and in the case of further improving the temperature correction accuracy, the difference between the corresponding actual temperature and the last time sequence actual temperature can also be obtained based on the difference between the current liner water temperature and the last time sequence liner water temperature, the collection time sequence, and the correlation curve between the liner water temperature and the liner actual temperature, so as to obtain the actual temperature of the current time sequence based on the last time sequence actual temperature. At this time, the liner initial parameter at least includes the last time sequence liner water temperature and the last time sequence liner actual temperature, and the liner temperature change rate is calculated based on the first influence data set and the liner temperature influence relationship, which comprises: The current liner water temperature and the last time sequence liner water temperature are obtained based on the first influence data set. The difference between the current liner water temperature and the last time sequence liner water temperature is taken as the input of the liner temperature influence relationship to obtain the liner temperature change rate.

[0030] In this case, the actual temperature change of the inner tank at the corresponding difference value in the inner tank temperature influence relationship is taken as the inner tank temperature change rate according to the difference between the current inner tank water temperature and the last time sequence inner tank water temperature, so that the current inner tank actual temperature is calculated according to the inner tank temperature change rate and the last time sequence inner tank actual temperature, and the current inner tank actual temperature is output as the current inner tank temperature. The water temperature change is obtained according to the difference between the water temperature collected by the inner tank sensor at the current time sequence and the water temperature collected by the inner tank sensor at the last time sequence, so that the corresponding actual temperature change of the inner tank is obtained.

[0031] According to the calculation formula of the metal inner tank temperature: Wherein, Q_in is the heat absorbed by the metal inner tank, Q_out is the heat dissipated by the metal inner tank, m is the mass of the metal inner tank, c is the specific heat capacity of the metal inner tank, is the change rate of the metal inner tank temperature with time.

[0032] In most intelligent household appliances, the equipment that needs to heat the inner tank will have a heat preservation layer or be embedded in a cabinet, cabinet body, etc. to reduce the temperature loss in the heating process, and also consider the heating allowance. Therefore, Q_out can be set to 0, and at this time: The mass and specific heat capacity of the metal inner tank do not change, so the change of the inner tank temperature is only related to the absorbed heat, and the absorbed heat is related to the temperature and time. In the running process, there are high-temperature water, etc. The water temperature will affect the actual temperature of the inner tank collected by the inner tank sensor. For example, when high-temperature water sprays or immerses the inner tank sensor, the inner tank sensor will collect the water temperature, thereby affecting the accuracy of the output actual temperature of the inner tank. Therefore, according to the difference between the front and rear water temperatures, the change of the actual temperature of the inner tank at the front and rear time sequences is obtained based on the inner tank temperature influence relationship, so that the current inner tank actual temperature is calculated. The actual temperature of the inner tank at each time sequence is corrected according to the inner tank temperature change rate obtained from the last time sequence inner tank temperature and the difference between the front and rear water temperatures, so as to avoid the problem that the output inner tank temperature is inaccurate due to the detection of the inner tank sensor being water temperature.

[0033] Of course, in the remaining embodiments, the actual temperature of the inner tank under the corresponding time sequence and the corresponding water temperature can also be obtained according to the inner tank temperature influence relationship. In the case where the inner tank water temperature does not change, the heating time sequence or the cooling time sequence will cause the change of the inner tank temperature, so the time sequence and the water temperature are double influence variables, and the inner tank temperature influence relationship at least includes the correlation curve of the time sequence and the actual temperature of the inner tank. At this time, according to the influence of the water temperature on the actual temperature of the inner tank in the whole time sequence, the inner tank temperature change rate in the whole time sequence is obtained, and then the inner tank actual temperature at the current time sequence is obtained according to the initial inner tank temperature and the inner tank temperature change rate. At this time, the initial parameters of the inner tank at least include the initial inner tank temperature.

[0034] It can be understood that, although the inner container temperature influence relationship is constructed by constructing the correlation curve of the time sequence-water temperature and the actual temperature of the inner container in this embodiment, the correlation model can also be constructed based on the neural network model in the remaining embodiments, and the corresponding actual temperature of the inner container is output by the correlation model. At this time, the process of calculating the inner container temperature change rate based on the inner container temperature influence relationship and correcting the current inner container temperature with the inner container temperature change rate is directly calculated in the hidden layer of the correlation model.

[0035] As the third embodiment of the present application, considering the case where there is liquid such as water in the inner container, the humidity in the inner container will change, and according to the temperature and humidity mutual influence relationship, it can be known that humidity will affect the change of temperature. At this time, the inner container temperature correction method further comprises: Obtaining temperature data under different humidity conditions to construct a temperature and humidity mutual influence relationship.

[0036] Taking humidity as the only variable, obtaining the influence relationship of humidity on temperature. At this time, the first influence data set further includes humidity data, and correcting the current inner container temperature with the inner container temperature change rate includes: Obtaining a first correction parameter from the inner container temperature change rate and the initial parameter of the inner container; Obtaining the humidity data in the first influence data set, obtaining a second correction parameter based on the temperature and humidity mutual influence relationship, the humidity data and the first correction parameter; Correcting the current inner container temperature with the second correction parameter.

[0037] The first correction parameter is the first corrected actual temperature of the inner container obtained from the inner container water temperature and the time sequence, which reflects the influence of the inner container water temperature and the time sequence on the actual temperature of the inner container. Based on the temperature and humidity mutual influence relationship, the influence of the current humidity on the temperature is obtained, the error caused by humidity in the first correction parameter is compensated by the second correction, and the second corrected actual temperature of the inner container is obtained as the second correction parameter. The second correction parameter is used as the actual temperature output of the inner container to correct the current inner container temperature.

[0038] In this embodiment, obtaining temperature data under different humidity conditions to construct a temperature and humidity mutual influence relationship includes: Setting a humidity interval, obtaining a corresponding temperature correction value according to the humidity interval to construct a temperature and humidity mutual influence relationship.

[0039] Small changes in humidity are difficult to cause changes in temperature, so a humidity interval is set, the humidity is classified according to different influence conditions, and the temperature correction value of each interval is calculated. The humidity interval and the temperature correction value are matched. At this time, obtaining the second correction parameter based on the temperature and humidity mutual influence relationship, the humidity data and the first correction parameter includes: According to the humidity data, the humidity interval in the temperature and humidity mutual influence relationship is matched, the temperature correction value corresponding to the humidity interval is called, and the second correction parameter is obtained by correcting the first correction parameter with the temperature correction value.

[0040] The humidity interval and the corresponding temperature correction value can be obtained by correlation analysis of laboratory simulation of temperature and humidity changes, or can be obtained by correlation analysis of historical temperature and humidity data in the actual operation process of the intelligent household appliance. In this embodiment, the humidity interval is divided into 0%, 20%, 40%, 60%, 80%, and 100% with 20% as a step, and the temperature correction value under each humidity interval is obtained. When the actual humidity data is obtained, it is determined which humidity interval it is in, and the temperature correction value of the humidity interval is called to correct the first correction parameter.

[0041] In other embodiments, the temperature correction value can be obtained first, and then the first correction parameter is used to compensate the temperature correction value. Meanwhile, the first influence data set can also include inner container sensor position data and environment data. Different positions of the inner container sensor will affect the inner container temperature influence relationship, and the environment data will also affect the inner container temperature influence relationship. Different inner container temperature influence relationships can be called according to the current inner container sensor position data and environment data, thereby further improving the accuracy of the actual inner container temperature correction.

[0042] Considering the influence of instantaneous temperature on the actual collection results of the inner container sensor, the collection data of the inner container sensor is obtained as the first influence data set, including: The inner container sensor performs real-time inner container water temperature and humidity collection according to the preset sampling rate and collection period to obtain real-time inner container water temperature data and real-time humidity data; The average values of the real-time inner container water temperature data and the real-time humidity data are calculated respectively as the first influence data set.

[0043] The real-time water temperature data and the real-time humidity data are collected by the preset sampling rate and the collection period, and the average values of the real-time water temperature data and the real-time humidity data in the collection period are calculated, and the average values are used as the first influence data to construct the first influence data set. In this embodiment, the preset sampling rate is 1 time / s, and the collection period is 3 s, that is, the average value of three sampling data is taken as the collection data. In other embodiments, the preset sampling rate and the collection period can be set according to the sampling parameters of the inner container sensor or the operation requirements of the intelligent household appliance.

[0044] As shown in Figure 2 As the fourth embodiment of the present application, the dishwashing machine operation control method uses the inner container temperature correction method as described above to realize dishwashing machine operation control, including the following steps: The inner container temperature correction method obtains a current inner container temperature, and performs a corresponding control action according to the current inner container temperature and a preset condition.

[0045] In this embodiment, after the inner container temperature correction method obtains the current inner container temperature, a corresponding control action is performed according to the preset condition matched by the current inner container temperature, so as to accurately determine the action that the dishwasher should perform according to the current inner container temperature, thereby improving the operation safety of the dishwasher.

[0046] The preset condition at least includes a first temperature threshold and a second temperature threshold. At this time, performing a corresponding control action according to the current inner container temperature and the preset condition includes: If the current inner container temperature is less than the first temperature threshold, a door opening action is performed; If the current inner container temperature is greater than the first temperature threshold and less than the second temperature threshold, a cooling action is performed by controlling part of the load; If the current inner container temperature is greater than the second temperature threshold, a cooling action is performed by controlling all of the load.

[0047] The first temperature threshold is a safe temperature for opening the door of the dishwasher, that is, a temperature at which the user will not be scalded when taking the bowl and chopsticks after opening the door of the dishwasher. In this embodiment, the first temperature threshold is 30°C. If the current inner container temperature is less than the first temperature threshold, it is considered that the user can open the door according to the need. It can be understood that the door opening action in this application refers to opening the door lock device, and the door plate is not locked. The second temperature threshold is set according to the load power of the refrigeration device of the dishwasher. When the actual temperature of the inner container of the dishwasher exceeds the second temperature threshold, it is considered that the refrigeration device of the dishwasher needs to be cooled at full speed by all of the load. When the actual temperature of the inner container of the dishwasher is less than the second temperature threshold but greater than the first temperature threshold, it is considered that the temperature of the inner container of the dishwasher is not at a safe temperature, but only part of the load of the refrigeration device of the dishwasher needs to perform cooling. By determining whether the current inner container temperature exceeds the second temperature threshold, part of the load of the refrigeration device is cooled or all of the load of the refrigeration device is cooled, which can reduce the working load and reduce the energy consumption when the temperature is low, and can accelerate the cooling speed by cooling at full speed by all of the load when the temperature is high, thereby achieving the effect of reducing the energy consumption.

[0048] The energy consumption of different loads of the refrigeration device of the dishwasher is not the same. For example, the refrigerant is a consumable product, which is continuously circulated and consumed during the refrigeration process, and needs to be replaced and supplemented. However, if the refrigeration is excluded and only a fan or the like is used for cooling, the loss of the refrigerant can be effectively reduced when the temperature is low. However, in the case where the temperature is high, the cooling effect of the fan or the like is poor, and a longer time or higher efficiency needs to be used to achieve cooling, and the cooling time is long. At this time, the energy consumption exceeds the loss of the refrigeration. Therefore, by setting the second temperature threshold, the cooling by all of the load is performed when the cooling by part of the load cannot meet the demand.

[0049] In this embodiment, the dishwasher operation control method further includes: Obtain the cooling power and cooling energy consumption of different loads within a unit time period; A load optimization model is constructed with minimum energy consumption as the optimization objective.

[0050] At this point, the preset condition is the minimum energy consumption. After obtaining the current inner liner temperature by executing the inner liner temperature correction method, the minimum energy consumption load combination for cooling is output by the load optimization model when the current inner liner temperature drops to the first temperature threshold. The cooling action is then performed using the minimum energy consumption load combination.

[0051] In other embodiments, multiple temperature thresholds can be set according to the cooling power and cooling energy consumption of different loads. For example, a temperature threshold and load control execution table can be set, and the load that should be cooled at the corresponding temperature can be called according to the temperature threshold and load control execution table to realize the corresponding execution control.

[0052] Understandably, when adapting to the dishwasher's structure, the temperature ranges divided by the first and second temperature thresholds can be set as three levels: A, B, and C. Adjustable settings can be incorporated into the dishwasher's internal structure to allow manufacturers to adjust the settings according to actual needs, thereby expanding the applicability and reducing adjustment costs.

[0053] The corresponding control actions based on the current inner tank temperature and preset conditions also include: If the current inner tank temperature is greater than the first temperature threshold and less than the second temperature threshold, control part of the load to perform a cooling action. After the first preset execution time is reached, determine whether the inner tank temperature is less than or equal to the first temperature threshold. If not, control all loads to perform a cooling action.

[0054] The first preset execution time can be a user-defined time, a factory preset time, or a combination of both. When either the user-defined time or the factory preset time is reached, it is considered that partial load cooling is insufficient to meet the actual demand, and all loads are controlled to perform cooling. The user-defined time reflects the user's cooling requirements, while the factory preset time takes into account the potential impact of different environments on the actual cooling power. Therefore, it presets the maximum time for partial load cooling at one time. If the temperature does not reach a safe level after this time, it is considered that partial load cannot meet the cooling requirements, and all loads are controlled to perform cooling.

[0055] like Figure 3 As shown in Embodiment 5 of this application, the preset conditions include at least the required cooling time, a first temperature threshold, a first cooling range, and a second cooling range.

[0056] The corresponding control actions based on the current inner tank temperature and preset conditions also include: The demand cooling amplitude is calculated according to the current liner temperature, the demand cooling time and the first temperature threshold value; If the current liner temperature is less than or equal to the first temperature threshold value, the door opening action is performed; If the current liner temperature is greater than the first temperature threshold value, when the demand cooling amplitude is in the first cooling amplitude range, the cooling action is performed by the partial load, and when the demand cooling amplitude is in the second cooling amplitude range, the cooling action is performed by the total load.

[0057] In the embodiment, the first cooling amplitude range and the second cooling amplitude range are set according to the cooling power of the load in advance considering the demand of the user for the cooling time or the demand for the cooling time at the factory. The first cooling amplitude range is constructed according to the liner temperature cooling condition when the cooling action is performed by the partial load, and the second cooling amplitude range is constructed according to the liner temperature cooling condition when the cooling action is performed by the total load. That is, the temperature change value of the liner in a unit time sequence when the cooling action is performed by the partial load is F1, and the temperature change value of the liner in a unit time sequence when the cooling action is performed by the total load is F2, the first cooling amplitude range is (0, F1], and the second cooling amplitude range is (F1, F2]. The demand cooling amplitude is calculated according to the current liner temperature, the demand cooling time and the first temperature threshold value as follows: Wherein, F is the demand cooling amplitude, T D is the current liner temperature, t x is the demand cooling time, T C is the first temperature threshold value.

[0058] If the current liner temperature is less than or equal to the first temperature threshold value, that is, F is less than or equal to 0, the door opening action is performed. At this time, single judgment or multiple judgment can be used. If single judgment is used, the demand cooling amplitude calculation is only performed when the current liner temperature is greater than the first temperature threshold value, at this time, the calculation is reduced and the efficiency is improved, and the door opening action can be directly performed when the current liner temperature is less than or equal to the first temperature threshold value; if multiple judgment is used, the demand cooling amplitude and the comparison process of the current liner temperature and the first temperature threshold value are performed at the same time, only when the demand cooling amplitude is less than or equal to 0 and the current liner temperature is less than the first temperature threshold value exist at the same time, the door opening action can be performed, otherwise, an alarm is performed to prompt program error for maintenance, multiple judgment can avoid the false opening of the door caused by misjudgment, although the calculation process is increased, but the safety is improved.

[0059] In the embodiment, the different loads are called to perform cooling according to the demand cooling amplitude matching the corresponding cooling amplitude range, the user demand is met at the same time, and the energy consumption is reduced.

[0060] In the case of the remaining embodiments, the cooling amplitude range can also be set to multiple according to the cooling power and the cooling energy consumption of the load.

[0061] Similarly, when the demand cooling range is greater than the first temperature threshold and is located in the first cooling range, the control part controls the partial load to perform the cooling action, and when the first preset execution time is reached, it is judged whether the liner temperature is less than or equal to the first temperature threshold. If not, control all loads to perform the cooling action.

[0062] Meanwhile, when the liner temperature is still greater than the first temperature threshold when the first preset execution time is reached, the first cooling range and the second cooling range are corrected at this time, and in the embodiment according to the second temperature threshold, the second temperature threshold is corrected at this time.

[0063] And in other embodiments, the maximum temperature of the high-temperature water should be constant, at this time, half of the demand cooling time is taken as the first preset execution time, and the expected temperature when the first preset execution time is reached is calculated according to the first cooling range. When the liner temperature is greater than the expected temperature, control all loads to perform the cooling action.

[0064] As the sixth embodiment of the present application, the liner temperature correction system is used to realize the liner temperature correction method, comprising: The liner sensor is used to collect water temperature data and air temperature data in different states of the liner, and the first influence data set is obtained according to the collection data of the liner sensor; The parameter correction module is used to calculate the liner temperature change rate in real time according to the first influence data set, and to perform the liner temperature correction according to the liner temperature change rate.

[0065] In this embodiment, the liner sensor is at least arranged in the liner to be able to collect water temperature data and air temperature data respectively. For example, in the intelligent household appliance with high-temperature water spraying, the liner sensor of the intelligent household appliance is at least arranged in the spraying range, and in the intelligent household appliance with high-temperature water immersion, the liner sensor of the intelligent household appliance is at least arranged in the immersion range. At this time, when the liner is in a non-spraying or non-immersion state, the liner sensor can collect air temperature data, and the air temperature data is used as the initial parameter of the liner, that is, the initial temperature of the liner. When the liner is in a spraying or immersion state, the liner sensor can collect water temperature data and perform actual temperature correction of the liner. Using one sensor to detect multiple temperature and humidity data can save cost while ensuring the accuracy of the output liner temperature data. The liner sensor is at least a sensor containing temperature collection, such as a temperature sensor, and in other embodiments, the liner sensor can also be a temperature and humidity sensor, a DHT11 temperature and humidity sensor containing a GPS module, or a comprehensive sensor combined with other combinations.

[0066] The parameter correction module pre-stores a liner temperature influence relationship. The parameter correction module is connected with the liner sensor. When the liner temperature correction is performed, the first influence data set is obtained through the liner sensor, the liner temperature influence relationship is called, the liner temperature change rate is calculated, and the liner temperature correction is performed. The parameter correction module can be connected with the control system of the smart household appliance to output the corrected liner temperature for use.

[0067] As shown in Figure 4 As shown in FIG. 1, as an embodiment of the present application, a dishwasher control system is used to implement a dishwasher operation control method. The dishwasher control system is connected with a dishwasher refrigeration device and a door lock device, and includes: A control chip is connected with the liner temperature correction system, the dishwasher refrigeration device, and the door lock device, and is used to control the dishwasher refrigeration device and the door lock device to perform corresponding actions according to the current liner temperature output by the liner temperature correction system.

[0068] The control chip controls the dishwasher refrigeration device and the door lock device to perform corresponding actions by receiving the current liner temperature output by the liner temperature correction system.

[0069] In the embodiment, the liner sensor is connected with the parameter correction module, the parameter correction module is connected with the control chip, and the control chip is connected with the dishwasher refrigeration device and the door lock module. However, in other embodiments, the parameter correction module can be designed as a subset of the control chip to achieve overall integration and reduce space occupation. At this time, the liner sensor is electrically connected with the control chip, and the first influence data set collected by the liner sensor is transmitted to the control chip through a wire.

[0070] The dishwasher refrigeration device generally includes an air compressor, a refrigerant box, a drainage pump, and a cooling fan. According to the cooling power and energy consumption difference of the air compressor, the refrigerant box, the drainage pump, and the cooling fan, part of the load and all the load cooling corresponding action modules are allocated. For example, when part of the load performs cooling, one or more of the following can be controlled to perform: driving the compressor motor, driving the drainage pump to drain water, driving the exhaust fan to operate, and opening one or more of the refrigerant boxes. When all the load performs cooling, all of the following are controlled to perform: driving the compressor motor, driving the drainage pump to drain water, driving the exhaust fan to operate, and opening the refrigerant box. It can be understood that when the dishwasher performs opening, the door lock device is released, the refrigeration device is closed, and when part of the load performs cooling, the remaining load is also closed to save electricity.

[0071] The compressor motor is composed of one or several heat exchange metal pipes and an air compressor. The pipes are wrapped around the outside of the dishwasher liner. Cold air is blown into the pipes by the compressor to exchange temperature with the metal liner, so as to achieve rapid cooling of the liner.

[0072] The door lock device usually includes a mechanical pull rod, a gear, a motor, and a hook for hooking the door inside the dishwasher to prevent the user from being scalded by opening the door halfway.

[0073] In the embodiment, the inner container sensor can be arranged on the top of the inner container of the dishwasher or on the top of the door panel of the dishwasher.

[0074] In the remaining embodiments, the dishwasher control system further includes: The interaction module is configured to output interaction information according to the current state of the dishwasher.

[0075] The interaction module can be an indicator light, which displays the current action of the dishwasher through different colors of the indicator light, such as green indicating that the door can be opened and red indicating that the temperature is being lowered. The indicator light can also be used to determine whether the dishwasher is currently operating normally by determining whether the indicator light is flashing.

[0076] The interaction module can also be a display screen that simultaneously displays the current inner container temperature of the dishwasher, whether the temperature is being lowered, whether the door can be opened, and the like, thereby achieving information interaction with the user.

[0077] The present application corrects the temperature collected by the inner container sensor in the intelligent household appliance through the inner container temperature correction method to avoid the influence of water temperature and the like on the actual inner container temperature. The present application also controls the full opening and partial opening of the refrigeration device load under different temperature conditions and different demand cooling time conditions, thereby improving the user experience while reducing the opening time of the load and saving electricity.

[0078] The above-described specific embodiments are preferred embodiments of the inner container temperature correction method, the dishwasher operation control method, and the related system of the present application, and do not limit the specific implementation range of the present application. The scope of the present application includes, but is not limited to, the specific embodiments.
