[0049] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details.

[0051] It should also be understood that the term “and / or” used in the specification and appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0052] As used in the specification and appended claims of this application, the term "if" can be interpreted as "when" or "uponce" or "in response to determining" or "in response to detecting", depending on the context. Similarly, the phrase "if it is determined" or "if [described condition or event] is detected" can be interpreted as meaning "uponce it is determined" or "in response to determining" or "uponce [described condition or event] is detected" or "in response to detecting [described condition or event]", depending on the context.

[0053] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0054] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0055] In actual applications, since the heating power of the washing pump of the washing equipment is about 1700W, the working power of the heating tube of the steam generator is also about 1700W, and the 220V civil electricity and wiring harness configuration parameters cannot drive a 3400W power load at the same time, the working time of the heating tube of the steam generator cannot overlap with the heating time of the dishwasher for water heating. Based on this, the working process of the steam generator needs to be controlled accordingly to avoid affecting other washing processes of the washing equipment.

[0056] See also Figure 1 , Figure 1 1 is a flow chart of a control method for a steam generator provided in an embodiment of the present application. In the embodiment of the present application, the execution subject of the control method for the steam generator is a washing device, wherein the washing device may be a dishwasher.

[0057] like Figure 1 As shown, the control method of the steam generator provided in one embodiment of the present application may include S101 to S103, which are described in detail as follows:

[0058] In S101, during the operation of a steam generator in a washing device, current temperature information corresponding to steam generated by the steam generator is obtained.

[0059] In the embodiment of the present application, since the steam generator is a device that uses thermal energy to heat water into steam, in order to avoid damage to the equipment caused by overheating of the steam generator, the washing device can obtain the current temperature information corresponding to the steam generated by the steam generator during the operation of the steam generator.

[0060] It should be noted that the current temperature information may include the steam temperature or the nozzle temperature of the steam injection nozzle.

[0061] In one implementation of the embodiment of the present application, the washing device can obtain the steam temperature in real time through a temperature detection module arranged in the steam generator. The temperature detection module may include devices such as a thermistor or a temperature sensor.

[0062] In another implementation of the embodiment of the present application, the washing device can obtain the nozzle temperature of the steam injection port in real time through a temperature detection module disposed in its own inner tank.

[0063] In one embodiment of the present application, in order to avoid the problem of dry burning of the steam generator, the washing device can be specifically Figure 2 The steps S201 to S202 shown control the steam generator to enter the operation phase, which are described in detail as follows:

[0064] In S201, in response to a steam generator start-up instruction, a water intake operation is performed to the steam generator.

[0065] In S202, after the water intake is completed, the heating tube in the steam generator is turned on to make the steam generator enter the operation stage.

[0066] In this embodiment, the washing device receives the steam generator start instruction may be: detecting that the user triggers a preset operation for the washing device. The preset operation may be determined according to actual needs and is not limited here. Exemplarily, the preset operation may be a time-triggered operation, and the washing device may be configured with a corresponding washing process when running, and the washing process includes trigger nodes of multiple key events, and the above key events include an event for starting the steam generator. In this case, if the washing device detects that the trigger node associated with the event of starting the steam generator has been reached, the operations of S201 to S202 are executed to perform the operation of turning on the steam generator.

[0067] After receiving the steam generator start-up instruction, in order to avoid the steam generator from drying out, the washing device can perform water supply operation to the steam generator through a water pump.

[0068] In some possible embodiments, the more water the steam generator takes in, the longer it takes to generate steam. At the same time, the longer the working time of the steam generator is, the progress of other washing processes of the washing device will be affected. Therefore, the washing device can determine the amount of water taken in by the steam generator according to the standard time for the steam generator to generate steam, and then determine the corresponding water taking time. The standard time can be set according to actual needs and is not limited here.

[0069] Based on this, in this embodiment, after the washing device performs the water intake operation to the steam generator for a certain period of time, the washing device can determine that the steam generator has completed the water intake.

[0070] Afterwards, the washing device may turn on the heating tube of the steam generator to allow the steam generator to enter an operation phase.

[0071] In S102, a control method for the steam generator is determined based on the current temperature information.

[0072] In the embodiment of the present application, after obtaining the above current temperature information, the washing device can compare the current temperature information with each set threshold value to determine the working scene of the steam generator at this time, and then determine the control method of the steam generator according to the working scene. Among them, each set threshold value can be determined according to actual needs and is not limited here.

[0073] It should be noted that the control method includes but is not limited to: a method of controlling the steam generator based on a first thermostat, a method of controlling the steam generator based on a heating tube relay, and a method of controlling the steam generator based on a second thermostat.

[0074] The type of the first thermostat is different from the type of the second thermostat.

[0075] In some possible embodiments, the first thermostat may be an automatic reset type thermostat, and the second thermostat may be a non-automatic reset type thermostat.

[0076] Based on this, in one embodiment of the present application, in order to further improve the accuracy of determining the control method of the steam generator and realize accurate control of the steam generator, the washing device can be specifically controlled by Figure 3 Steps S301 to S303 shown determine the control mode of the steam generator, which are described in detail as follows:

[0077] In S301, when the steam temperature or the nozzle temperature is less than a first threshold value, it is determined that the control mode is to control the steam generator based on a first thermostat; the first thermostat is used to disconnect when it senses that the steam temperature or the nozzle temperature is greater than or equal to the first threshold value, and after disconnection, close when it senses that the target steam temperature or the target nozzle temperature is less than or equal to a second threshold value; the first threshold value is greater than the second threshold value.

[0078] In this embodiment, when the washing device detects that the steam temperature or the nozzle temperature is less than or equal to the first threshold, it indicates that the steam generator is in a normal working scenario, that is, the steam generator is at a normal working temperature. Therefore, in order to ensure that the steam generator can generate steam normally and avoid overheating of the steam generator, the washing device can determine the control mode to control the steam generator based on the first thermostat. The first threshold can be determined according to the upper limit value of the normal working temperature of the steam generator.

[0079] Exemplarily, the normal operating temperature of the steam generator is generally (100°C, 210°C), and therefore, the first threshold value may be determined to be 210°C.

[0080] It should be noted that the first thermostat is used to disconnect when sensing that the steam temperature or the nozzle temperature is greater than or equal to the first threshold, and after disconnecting, close when sensing that the target steam temperature or the target nozzle temperature is less than or equal to the second threshold. Among them, the first threshold is greater than the second threshold. The second threshold can be determined according to actual needs and is not limited here. For example, the second threshold = the first threshold - 10 ° C.

[0081] In S302, when the steam temperature or the nozzle temperature is greater than the first threshold value and less than a third threshold value, it is determined that the control method is to control the steam generator based on a heating tube relay.

[0082] In this embodiment, when the washing device detects that the steam temperature or the nozzle temperature is greater than the first threshold value and less than the third threshold value, it indicates that the steam generator is in a controllable abnormal working scene and the first thermostat is abnormal, that is, although the current working temperature of the steam generator exceeds its normal working temperature, the steam generator can still continue to work. Therefore, in order to avoid further overheating of the steam generator and thus cause the steam generator to fail, the washing device can determine the control method to control the steam generator based on the heating tube relay. Among them, the third threshold value can be determined according to the upper limit value of the working temperature when the steam generator is in a controllable abnormal working scene.

[0083] Exemplarily, the third threshold may be determined to be 270°C.

[0084] In S303, when the steam temperature or the nozzle temperature is greater than or equal to the third threshold, it is determined that the control mode is to control the steam generator based on a second thermostat; the second thermostat is used to disconnect when it senses that the steam temperature or the nozzle temperature is greater than or equal to the third threshold.

[0085] In this embodiment, when the washing device detects that the steam temperature or the nozzle temperature is greater than or equal to the third threshold value, it means that the steam generator is in an uncontrollable abnormal working scenario, and both the first thermostat and the heating tube relay are abnormal. In other words, the temperature is too high at this time, causing the steam generator to be abnormal, that is, the steam generator fails. Therefore, in order to avoid accidents, the washing device can determine the control method to control the steam generator based on the second thermostat.

[0086] It should be noted that the second thermostat is used to disconnect when it senses that the steam temperature or the nozzle temperature is greater than or equal to the third threshold.

[0087] In S103, the steam generator is controlled based on the control method.

[0088] In the embodiment of the present application, after determining the control method for the steam generator, the washing device can control the steam generator based on the determined control method.

[0089] Specifically, when the control mode is to control the steam generator based on the first thermostat, the first thermostat can obtain the steam temperature or the nozzle temperature in real time, and then the first thermostat disconnects when sensing that the steam temperature or the nozzle temperature is greater than or equal to the first threshold value, so as to automatically cut off the power supply of the heating tube, that is, stop the heating operation of the heating tube. After disconnection, the first thermostat still obtains the steam temperature or the nozzle temperature in real time, and closes when sensing that the target steam temperature or the target nozzle temperature is less than or equal to the second threshold value, so as to automatically connect the power supply of the heating tube, that is, continue the heating operation of the heating tube to continue to generate steam.

[0090] It can be understood that when the steam temperature or the nozzle temperature is less than the first threshold value, the heating tube of the steam generator remains in the working state.

[0091] When the control mode is to control the steam generator based on the heating tube relay, since the first thermostat has failed at this time, the heating tube relay can obtain the steam temperature or the nozzle temperature in real time. After that, the heating tube relay can control the heating tube to be disconnected when sensing that the steam temperature or the nozzle temperature is greater than or equal to the third threshold value, so as to stop the heating operation of the heating tube. After disconnection, the heating tube relay can still obtain the steam temperature or the nozzle temperature in real time, and control the heating tube to be connected when sensing that the target steam temperature or the target nozzle temperature is less than or equal to the fourth threshold value, so as to control the heating tube to continue heating and continue to generate steam.

[0092] When the control method is to control the steam generator based on the second thermostat, since the first thermostat and the heating tube relay are both invalid at this time, the second thermostat can obtain the steam temperature or the nozzle temperature in real time. Afterwards, the second thermostat can control the heating tube to disconnect when it senses that the steam temperature or the nozzle temperature is greater than or equal to the third threshold value to stop the heating operation of the heating tube.

[0093] From the above, it can be seen that the control method of a steam generator provided in the embodiment of the present application obtains the current temperature information corresponding to the steam generated by the steam generator during the operation of the steam generator in the washing equipment; determines the control method of the steam generator based on the current temperature information; and controls the steam generator based on the control method. Compared with the prior art, the present method can obtain the current temperature information corresponding to the steam in real time during the operation of the steam generator, and determine the control method matching the steam generator in real time based on the current temperature information, so as to realize real-time and accurate control of the steam generator, thereby improving the control accuracy of the steam generator.

[0094] In one embodiment of the present application, when the washing device detects that the second thermostat is in the disconnected state, it indicates that the steam generator is abnormal, that is, the steam generator has failed. Therefore, in order to avoid accidents caused by further overheating of the steam generator, the washing device can specifically Figure 4 Steps S401 to S402 shown are used to control the steam generator.

[0095] See also Figure 4 , Figure 4 FIG. 1 is a flow chart of a control method for a steam generator provided in another embodiment of the present application. Figure 4 As shown, in this embodiment, after the washing device controls the steam generator by controlling the steam generator based on the second thermostat, steps S401 to S402 may be performed, which are described in detail as follows:

[0096] In S401, when it is detected that the second thermostat is in the disconnected state, a water supply operation is performed to the steam generator.

[0097] In S402, after the water intake is completed, the steam generator is turned off.

[0098] In this embodiment, when the washing device detects that the second thermostat is in the disconnected state, it indicates that the steam generator is abnormal, that is, the steam generator has failed. Therefore, in order to avoid accidents caused by further overheating of the steam generator, the washing device can perform water supply operation to the steam generator with a water pump so that the steam generator body can be cooled by water.

[0099] It should be noted that, since the steam generator has failed at this time, that is, the steam generator cannot work, the steam generator can be turned off immediately after the washing device has finished filling with water.

[0100] It can be seen from the above that the method provided in this embodiment can prevent the steam generator from causing an accident due to further overheating, and achieve the purpose of cooling the steam generator.

[0101] In another embodiment of the present application, in order to improve working efficiency and avoid controlling the steam generator to continue working when the heating pipe of the steam generator is abnormal and cannot be heated, the washing device can also perform the following steps after executing step S101: Figure 5 Steps S501 to S503 are described in detail as follows:

[0102] In S501, a plurality of temperature values ​​of the steam are obtained within a set time period.

[0103] In S502, the temperature variation range of the steam within the set time period is calculated based on the steam temperature and the multiple temperature values.

[0104] In S503, if the temperature variation range is less than or equal to the set range, the steam generator is turned off, and a prompt message indicating that the steam generator is abnormal is output.

[0105] It should be noted that the current temperature information is the steam temperature.

[0106] In this embodiment, during the operation of the steam generator, after the washing device obtains the current temperature information, in order to detect in real time whether the heating tube of the steam generator is abnormal and cannot be heated, the washing device can continue to obtain multiple temperature values ​​of the steam generated by the steam generator within a set time period.

[0107] Since the heating tube can be heated normally when there is no abnormality, that is, the temperature of the steam generated by the steam generator will change, the washing equipment can calculate the temperature change range of the steam within the set time period based on the steam temperature and multiple temperature values.

[0108] In some possible embodiments, the washing device may determine the steam temperature as the initial temperature, and calculate the differences between the initial temperature and a plurality of temperature values, thereby obtaining a difference set.

[0109] Afterwards, the washing device can determine the temperature variation of the steam within a set time period based on the above difference set.

[0110] In this embodiment, after obtaining the above temperature variation range, the washing device can compare the temperature variation range with the set range, wherein the set range can be determined according to actual needs and is not limited here.

[0111] When the washing equipment detects that the temperature change amplitude is less than or equal to the set amplitude, it means that the steam has not changed within the set time. In other words, the heating tube of the steam generator is abnormal and cannot be heated. Therefore, the washing equipment can turn off the steam generator to avoid affecting its other washing processes; the washing equipment can also output a prompt message of the steam generator abnormality so that relevant personnel can repair the steam generator.

[0112] It can be seen from the above that the method provided in this embodiment can improve working efficiency and avoid controlling the steam generator to continue working when the heating tube of the steam generator is abnormal and cannot be heated.

[0113] In another embodiment of the present application, in order to avoid the influence of the steam generator on other washing processes of the washing device, the washing device can detect the running time of the steam generator in real time after executing step S103, and detect whether the running time reaches the target time. The target time is used to describe the standard working time of the steam generator.

[0114] In this embodiment, after the washing device detects that the above-mentioned operating time reaches the target time, it indicates that the steam generator has completed the work of generating steam, that is, the steam generator can end the work of generating steam, and therefore, the washing device can turn off the steam generator.

[0115] Since the steam generator is turned off, the washing device can control itself to continue to perform the corresponding washing program.

[0116] In another embodiment of the present application, in order to improve work efficiency, the steam generator can send an abnormality signal to the washing device after detecting that the steam generator itself is abnormal. After detecting the abnormality signal, the washing device can turn off the steam generator and execute a washing program corresponding to itself.

[0117] In another embodiment of the present application, in order to achieve the correct shutdown of the steam generator to avoid the harm caused by improper shutdown of the steam generator, the washing device can specifically perform the following steps, which are detailed as follows:

[0118] Turning off the heating tube of the steam generator;

[0119] After a set time, the water pump is turned off; the water pump is used to supply water to the steam generator so that the steam generator generates the steam.

[0120] In this embodiment, the washing device may first turn off the heating tube of the steam generator to stop the heating operation of the heating tube.

[0121] After the steam generator is cooled down for a set period of time, the washing device can turn off the water pump to stop the water supply operation to the steam generator.

[0122] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0123] Corresponding to the control method of a steam generator described in the above embodiment, Figure 6 The structure diagram of a control device for a steam generator provided in an embodiment of the present application is shown. For the convenience of explanation, only the part related to the embodiment of the present application is shown. Figure 6 The control device 600 of the steam generator includes: a first acquisition unit 61, a first mode determination unit 62 and a control unit 63. Among them:

[0124] The first acquisition unit 61 is used to acquire current temperature information corresponding to steam generated by the steam generator during operation of the steam generator in the washing device.
