In view of this, according to a first aspect of the present invention, there is provided a control method of a steam generating device including a chamber, a heating assembly, a liquid supply assembly, and a valve body, the control method including: determining the number of steam release times based on the steam generation instruction; and controlling the heating assembly, the liquid supply assembly and the valve body to work according to the steam release times.

The control method of the steam generating device is used for controlling the steam generating device. The steam generating device comprises a cavity, a heating component for heating the cavity, a liquid supply component for supplying liquid into the cavity and a valve body for controlling steam output. In the process of generating steam by the steam generating device, the liquid supply assembly is controlled to input liquid into the cavity, the heating assembly heats the cavity, so that the liquid in the cavity is heated and vaporized to form steam, and the valve body controls whether the cavity is exhausted or not. It is worth to say that, in the operation process of the liquid supply assembly and the heating assembly, the control valve body keeps the closed state, steam is continuously generated in the cavity, and the heating assembly continuously heats the steam, so that high-temperature and high-pressure steam is formed in the cavity.

The control method of the steam generating device comprises the step of receiving a steam generating instruction, wherein the steam generating instruction can be selected as a control instruction manually input to the steam generating device by a user. After receiving the steam generation instruction, the number of times of steam release in the operation process of the steam generation device can be determined according to the received steam generation instruction. According to different steam release times, the operation of the heating component, the liquid supply component and the valve body in the steam generating device is controlled, so that the steam generating device can generate high-temperature and high-pressure steam.

In some embodiments, a plurality of preset operating modes are stored in the steam generating device, the plurality of preset operating modes including a single large output of steam and a plurality of small outputs of steam.

In these embodiments, the user controls the operation of the steam generating device by selecting a pre-stored operation mode in the steam generating device.

In other embodiments, a user can manually control the operating parameters of the steam generating device.

In these embodiments, the user can set the steam parameters of the steam generation device, such as the number of steam releases, the steam temperature, and the steam pressure. The steam generating device controls the operation of the steam generating device according to the steam parameters set by the user.

According to the control method of the steam generating device, provided by the invention, the steam release times, the steam temperature and the steam pressure of the steam generating device can be controlled according to the steam generation instruction input by a user, so that the steam generating device can output steam in different modes, the steam generating device can be further adapted to different application scenes, and the use experience of the user is improved.

In addition, according to the control method of the steam generating device in the technical scheme provided by the invention, the control method can also have the following additional technical characteristics:

in one possible design, the steps of controlling the operation of the heating assembly, the liquid supply assembly and the valve body according to the number of times of steam release specifically comprise: controlling the liquid supply assembly to convey a predetermined amount of liquid into the cavity based on the number of times of steam release being one time; controlling the heating assembly to heat the cavity so as to obtain steam; the control valve body opens the outlet of the cavity to discharge the steam.

In the design, when the steam generating device is determined to release steam only once in the operation process according to the steam generating instruction, the liquid supply assembly is controlled to supply liquid in the cavity, and the preset amount of liquid supply is associated with the steam generating instruction. After the liquid supply assembly finishes liquid supply or in the process of supplying liquid by the liquid supply assembly, the heating assembly is controlled to start to operate, the heating assembly is arranged at a position close to the cavity, and the heating assembly can heat liquid in the cavity during operation so that the liquid in the cavity is vaporized to generate steam. Because the heating component continuously operates, liquid in the cavity can be vaporized into steam, the steam can be further heated, and the temperature of the steam is continuously increased. The heating assembly is controlled to operate under the condition that the valve body is kept closed, so that the temperature and the pressure of steam in the cavity can be continuously increased, and when the steam in the cavity meets the requirements of temperature and pressure, the valve body is controlled to open an outlet of the cavity to discharge the steam.

According to the invention, the liquid supply assembly and the heating assembly are controlled to continuously operate under the state that the valve body is kept closed, so that the temperature and the pressure of steam in the cavity are continuously increased, and under the condition that the temperature and the pressure of the steam meet the temperature and pressure requirements, the valve body is controlled to be opened to output high-temperature high-pressure steam, so that the effect of outputting a large amount of high-temperature high-pressure steam at one time is realized.

The steam generation command includes one or a combination of steam parameters such as steam temperature, steam pressure, steam amount and the like of the output steam of the steam generation device. The steam generator can determine a predetermined amount of liquid supply based on the steam parameters in the steam generation command.

In some embodiments, the heating assembly and the liquid supply assembly are controlled to operate simultaneously with the valve body remaining closed.

In the embodiments, the heating component and the liquid supply component operate simultaneously, and under the condition that the liquid amount in the cavity is small, the heating component operates to enable the liquid to be quickly heated and vaporized, so that the vaporization efficiency of the liquid in the cavity is improved, and the steam output efficiency of the steam generating device is further improved.

In other embodiments, the liquid supply assembly is controlled to supply liquid to the cavity in a state that the valve body is kept closed, and the heating assembly is controlled to start to operate to vaporize the liquid in the cavity under the condition that the liquid in the cavity reaches the liquid quantity meeting the requirement. Because the liquid supply assembly is controlled to supply liquid in the cavity, the steam quantity of steam generated by the steam generating device can be accurately controlled, the problem of insufficient steam quantity or excessive steam quantity is avoided, the problem of overheating of the heating assembly is also avoided, and the waste of energy sources is reduced on the premise that the steam generated by the steam generating device meets the expectations.

In one possible design, the step of controlling the valve body to open the outlet of the cavity specifically includes: acquiring a temperature value in the cavity; and controlling the valve body to open the outlet based on the temperature value reaching a preset temperature value.

In this design, steam generation device still includes temperature acquisition device, and temperature acquisition device can gather the temperature value in the cavity. The steam generating device can compare the acquired actual temperature value with a preset temperature value in the steam generating instruction, so as to control the opening and closing state of a valve body of the steam generating device. Specifically, when the actual temperature value in the cavity is detected to be increased to the preset temperature value, it is determined that the steam in the cavity meets the output requirement of the steam, the valve body is switched to be in an open state, and the steam in the cavity is discharged.

When the valve body is in a closed state, after the liquid is vaporized into steam, the heating assembly is continuously controlled to operate to heat the steam, so that the steam is continuously heated. Under the condition that the temperature value of the steam is increased to a preset temperature value, the steam is output, and the effect of accurately controlling the temperature of the output steam is achieved.

In one possible design, the range of preset temperature values is: 100 ℃ or higher and 200 ℃ or lower.

In the design, the range of the preset temperature value is less than or equal to 200 ℃ and more than or equal to 100 ℃. When the steam temperature reaches the value range of the preset temperature value, the steam can be ensured to have higher temperature, and the cooking effect or the cleaning effect can be improved when the steam is used for cooking or cleaning.

In one possible design, the step of controlling the valve body to open the outlet specifically includes: controlling the valve body to open the outlet; and controlling the valve body to close the outlet based on the opening time of the outlet reaching the preset time.

In this design, the open and closed state of the valve body can control whether the steam in the cavity is output. When the valve body is in a closed state, steam is continuously generated in the cavity in the process of continuous operation of the heating assembly, and the temperature of the steam is continuously raised, so that the steam cannot be discharged through the steam outlet of the cavity. When the valve body is in an open state, steam can be discharged out of the cavity through a steam outlet of the cavity.

And in the process of controlling the valve body, determining the preset duration of the valve body in the opening state according to the preset steam output quantity in the steam generation instruction. And after the control valve body is switched from the closed state to the open state, timing the opening time of the valve body, and under the condition that the opening time of the valve body reaches the preset time, judging that the output steam reaches the preset steam output quantity, and then controlling the valve body to be closed. According to the invention, the opening time of the valve body is controlled, so that the steam quantity of the output steam of the steam generating device is accurately controlled, and the condition that the output steam quantity cannot meet the steam quantity requirement is avoided.

In one possible design, the range of preset durations is: 3 seconds or more and 60 seconds or less.

In this design, the value range of the preset duration is set to 60 seconds or less and 3 seconds or more. The duration that the valve body was opened is correlated with steam output of steam generator, if the duration of opening of valve body is too short, can lead to the unable complete discharge of steam in the cavity, if the duration of opening of valve body is overlength, because the valve body is in the stage of opening, can lead to steam generator to produce the time interval overlength of steam in the cavity, thereby influence whole steam generator's operating efficiency. The invention limits the opening time of the valve body in the steam generating device to be less than or equal to 60 seconds and more than or equal to 3 seconds, thereby reducing the time interval between two adjacent times of steam generation on the premise of ensuring that the steam generating device in the cavity can completely discharge.

In one possible design, the steps of controlling the operation of the heating assembly, the liquid supply assembly and the valve body according to the number of times of steam release specifically comprise: based on the steam release times being more than 1, the heating component, the liquid supply component and the valve body are controlled to circularly operate according to the steam release times.

In this design, in the case that the number of times of steam release is multiple, the steam generating device is controlled to generate multiple times of steam, and it is understood that in the process that the steam generating device generates high-temperature and high-pressure steam, the liquid and the steam need to be continuously heated in the state that the valve body is closed, so as to generate the high-temperature and high-pressure steam in the cavity. In order to ensure that the steam temperature, the steam pressure and the steam quantity of each steam generation are the same, the operation states of the liquid supply assembly, the heating assembly and the valve body are controlled to be the same in the process of each steam generation. According to the invention, the liquid supply assembly, the heating assembly and the valve body are controlled to circularly operate, and the circulation times are the same as the steam release times, so that the same parameters of steam released by the steam generating device each time can be ensured, the operation stability of the steam generating device is improved, and the steam generating device is prevented from releasing the steam with different parameters under the condition of releasing the steam for many times.

It will be appreciated that when cleaning by steam, for example: when the steam generating device is controlled to output high-temperature and high-pressure steam for many times, the steam temperature, the steam pressure and the steam quantity of each time are required to be ensured to be within a preset range, so that the steam parameters of the output steam can be ensured to be the same through controlling the circulating operation of the liquid supply assembly, the heating assembly and the valve body in the steam generating device, the time interval between the two adjacent output steam can be ensured to be the same, and the cleaning effect of tableware can be improved through steam.

In one possible design, the steps of controlling the heating assembly, the liquid supply assembly and the valve body to operate circularly according to the steam release times specifically comprise: determining a first cycle of the valve body, a second cycle of the liquid supply assembly and a third cycle of the heating assembly according to the steam generation instruction; and controlling the valve body, the liquid supply assembly and the heating assembly to circularly operate according to the first circulation period, the second circulation period, the third circulation period and the steam release times.

In this design, the steam generation command includes one or a combination of steam parameters such as a steam temperature, a steam pressure, and a steam amount of the output steam of the steam generating device. According to the steam parameters in the steam generation command, the operation parameters of the liquid supply assembly, the heating assembly and the valve body in each steam generation process of the steam generation device can be determined. The operation parameters comprise not only the operation power and other parameters, but also the circulation period of the liquid supply assembly, the heating assembly and the valve body, namely, the first circulation period corresponding to the valve body, the second circulation period corresponding to the liquid supply assembly and the third circulation period corresponding to the heating assembly. In the process of controlling the operation of the steam generating device, the control valve body operates according to the first cycle, the liquid supply assembly is controlled to operate according to the second cycle, and the heating assembly is controlled to operate according to the third cycle. According to the invention, the valve body, the liquid supply assembly and the heating assembly are controlled to operate according to the first cycle period, the second cycle period and the third cycle period, so that the steam generating device can output steam for multiple times, and parameters of the steam output each time are the same, so that the operation stability of the steam generating device is further improved.

In one possible design, the operating time of the steam generator is a common multiple of the first cycle period, the second cycle period, and the third cycle period.

In this design, the first cycle period corresponding to the valve body includes a period in which the valve body is in a closed state and a period in which the valve body is in an open state, and it is understood that, during operation of the steam generating device, the liquid in the cavity continuously generates steam in the closed state of the valve body, the steam continuously heats up, and the steam in the cavity starts to be output in the open state of the valve body. Therefore, the operation time of the steam generator can be obtained by multiplying the first cycle period by the number of times of steam release. Through setting the working time length to the common multiple of the third cycle period, the second cycle period and the first cycle period, the valve body, the heating component and the liquid supply component can stop running simultaneously in the running process of the steam generating device, so that the running stability of the steam generating device is improved, and the valve body, the heating component and the liquid supply component are prevented from running in disorder in the working time length.

In one possible design, during a first cycle, controlling the valve body to open the outlet based on the valve body closing the outlet for a first period of time; in the second cycle period, controlling the liquid supply assembly to stop running based on the fact that the liquid supply assembly runs for a second duration; and controlling the heating assembly to stop running based on the heating assembly running for a third duration in a third cycle period.

In the design, the valve body is switched between the closed state and the open state in a first cycle period, the valve body is in the closed state in the beginning stage of the first cycle period, the liquid supply assembly and the heating assembly continuously operate at the moment, namely, the valve body keeps the closed state in a first time period, meanwhile, the liquid supply assembly keeps the operating state in a second time period before the liquid supply assembly in a second cycle period to supply liquid in the cavity, and the heating assembly operates in a third time period before the liquid supply assembly in a third cycle period to heat the cavity. When the valve body is switched from the closed state to the open state, the steam in the cavity is discharged out of the precursor through the steam outlet, and the heating assembly and the liquid supply assembly are controlled to stop running. The control mode can ensure that the steam generating device circularly generates steam, ensures that the steam generated each time is the steam with fixed steam parameters, and improves the operation stability of the steam generating device in the operation mode of releasing the steam for many times.

In some embodiments, the first time period is equal to or greater than the second time period and the first time period is equal to or greater than the third time period.

In these embodiments, the liquid supply assembly and the heating assembly continue to operate for a first period of time while the valve body is in the closed state. When the valve body is in an open state, the liquid supply assembly and the heating assembly stop running in the process of releasing the steam in the cavity, so that the steam generator stops running in the process of releasing the steam, the waste of energy sources is reduced, and the problem that the steam temperature and the steam pressure caused by the operation of the liquid supply assembly and the heating assembly in the steam release process cannot meet the requirements is solved.

In other embodiments, the second time period is the same as the third time period.

In these embodiments, the liquid supply assembly and the heating assembly are operated simultaneously, and under the condition that the liquid amount in the cavity is small, the heating assembly can be operated to enable the liquid to be heated and vaporized rapidly, so that the vaporization efficiency of the liquid in the cavity is improved, and the efficiency of the steam generating device for outputting steam is further improved.

In one possible design, the valve body is selected as a normally closed solenoid valve, or the valve body is selected as a normally open solenoid valve.

It should be noted that, without conflict, the embodiments of the present invention and features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those described herein, and therefore the scope of the present invention is not limited to the specific embodiments disclosed below.

A steam generating apparatus, a control method, an apparatus, a storage medium, and a dishwasher according to some embodiments of the present invention are described below with reference to fig. 1 to 7.

Embodiment one:

as shown in fig. 1, in a first embodiment of the present invention, there is provided a control method of a steam generating device including a heating assembly, a chamber, a valve body, and a liquid supply assembly.

The control method comprises the following steps:

102, acquiring a steam generation instruction;

104, determining the number of steam release times according to the steam generation instruction;

and 106, controlling a liquid supply assembly, a valve body and a heating assembly in the steam generating device according to the steam release times.

The control method of the steam generating device provided by the embodiment is used for controlling the steam generating device. The steam generating device comprises a cavity, a heating component for heating the cavity, a liquid supply component for supplying liquid into the cavity and a valve body for controlling steam output. In the process of generating steam by the steam generating device, the liquid supply assembly is controlled to input liquid into the cavity, the heating assembly heats the cavity, so that the liquid in the cavity is heated and vaporized to form steam, and the valve body controls whether the cavity is exhausted or not. It is worth to say that, in the operation process of the liquid supply assembly and the heating assembly, the control valve body keeps the closed state, steam is continuously generated in the cavity, and the heating assembly continuously heats the steam, so that high-temperature and high-pressure steam is formed in the cavity.

The control method of the steam generating device provided by the embodiment comprises the step of receiving a steam generating instruction, wherein the steam generating instruction can be selected as a control instruction manually input to the steam generating device by a user. After receiving the steam generation instruction, the number of times of steam release in the operation process of the steam generation device can be determined according to the received steam generation instruction. According to different steam release times, the operation of the heating component, the liquid supply component and the valve body in the steam generating device is controlled, so that the steam generating device can generate high-temperature and high-pressure steam.

According to the control method of the steam generating device, provided by the embodiment, the steam release times, the steam temperature and the steam pressure of the steam generating device can be controlled according to the steam generation instruction input by a user, so that the steam generating device can output steam in different modes, the steam generating device can be further adapted to different application scenes, and the use experience of the user is improved.

As shown in fig. 2, in any of the above embodiments, controlling the liquid supply assembly, the valve body, and the heating assembly in the steam generating device according to the number of steam releases includes:

step 202, controlling the liquid supply assembly to convey a preset amount of liquid into the cavity under the condition that the steam release frequency is detected to be one time;

step 204, controlling the operation of the heating assembly;

at step 206, the valve body is switched to an open state.

In this embodiment, in case it is determined that the steam generating device needs to release only one steam during operation according to the steam generating instruction, the liquid supply assembly is controlled to supply liquid into the cavity, and the predetermined amount of liquid supply is associated with the steam generating instruction. After the liquid supply assembly finishes liquid supply or in the process of supplying liquid by the liquid supply assembly, the heating assembly is controlled to start to operate, the heating assembly is arranged at a position close to the cavity, and the heating assembly can heat liquid in the cavity during operation so that the liquid in the cavity is vaporized to generate steam. Because the heating component continuously operates, liquid in the cavity can be vaporized into steam, the steam can be further heated, and the temperature of the steam is continuously increased. The heating assembly is controlled to operate under the condition that the valve body is kept closed, so that the temperature and the pressure of steam in the cavity can be continuously increased, and when the steam in the cavity meets the requirements of temperature and pressure, the valve body is controlled to open an outlet of the cavity to discharge the steam.

According to the embodiment, the liquid supply assembly and the heating assembly are controlled to continuously operate under the condition that the valve body is kept closed, so that steam in the cavity is continuously heated and boosted, and under the condition that the temperature and the pressure of the steam reach the temperature and pressure requirements, the valve body is controlled to be opened to output high-temperature high-pressure steam, so that the effect of outputting a large amount of high-temperature high-pressure steam at one time is achieved.

As shown in fig. 3, in any of the above embodiments, the valve body is switched to the open state, including:

step 302, collecting a temperature value in a cavity;

step 304, when the temperature value of the cavity is detected to rise to the preset temperature value, the valve body is switched to an open state.

In this embodiment, the steam generating device further comprises a temperature acquisition device, which is capable of acquiring a temperature value in the cavity. The steam generating device can compare the acquired actual temperature value with a preset temperature value in the steam generating instruction, so as to control the opening and closing state of a valve body of the steam generating device. Specifically, when the actual temperature value in the cavity is detected to be increased to the preset temperature value, it is determined that the steam in the cavity meets the output requirement of the steam, the valve body is switched to be in an open state, and the steam in the cavity is discharged.

In any of the above embodiments, the range of preset temperature values is: 100 ℃ or higher and 200 ℃ or lower.

In this embodiment, the preset temperature value is set to a value of 200 ℃ or less and 100 ℃ or more. When the steam temperature reaches the value range of the preset temperature value, the steam can be ensured to have higher temperature, and the cooking effect or the cleaning effect can be improved when the steam is used for cooking or cleaning.

As shown in fig. 4, in any of the above embodiments, switching the valve body to the open state includes:

step 402, timing the opening duration of the valve body in an opened state;

and step 404, when the opening time is detected to reach the preset time, controlling the valve body to switch to the closing state.

In this embodiment, the open and closed states of the valve body can control whether the steam in the cavity is output. When the valve body is in a closed state, steam is continuously generated in the cavity in the process of continuous operation of the heating assembly, and the temperature of the steam is continuously raised, so that the steam cannot be discharged through the steam outlet of the cavity. When the valve body is in an open state, steam can be discharged out of the cavity through a steam outlet of the cavity.

And in the process of controlling the valve body, determining the preset duration of the valve body in the opening state according to the preset steam output quantity in the steam generation instruction. And after the control valve body is switched from the closed state to the open state, timing the opening time of the valve body, and under the condition that the opening time of the valve body reaches the preset time, judging that the output steam reaches the preset steam output quantity, and then controlling the valve body to be closed. According to the embodiment, the opening time of the valve body is controlled, so that the steam quantity of the output steam of the steam generating device is accurately controlled, and the situation that the output steam quantity cannot meet the steam quantity requirement is avoided.

In any of the foregoing embodiments, the range of the preset duration is: 3 seconds or more and 60 seconds or less.

In this embodiment, the value range of the preset duration is set to 60 seconds or less and 3 seconds or more. The duration that the valve body was opened is correlated with steam output of steam generator, if the duration of opening of valve body is too short, can lead to the unable complete discharge of steam in the cavity, if the duration of opening of valve body is overlength, because the valve body is in the stage of opening, can lead to steam generator to produce the time interval overlength of steam in the cavity, thereby influence whole steam generator's operating efficiency. According to the embodiment, the opening time of the valve body in the steam generating device is limited to 60 seconds or less and 3 seconds or more, so that the time interval between two adjacent times of steam generation is reduced on the premise that the steam generating device in the cavity can be completely discharged.

In any of the above embodiments, controlling the liquid supply assembly, the valve body, and the heating assembly in the steam generating device according to the number of steam releases includes:

and under the condition that the steam release times are detected to be multiple times, performing circulating operation control on the valve body, the liquid supply assembly and the heating assembly according to the steam release times.

In this embodiment, in the case where the number of times of steam release is a plurality of times, the steam generating device is controlled to generate a plurality of times of steam, and it is understood that in the process of generating high-temperature and high-pressure steam by the steam generating device, it is necessary to continuously heat the liquid and the steam in a state where the valve body is closed, so as to generate the high-temperature and high-pressure steam in the cavity. In order to ensure that the steam temperature, the steam pressure and the steam quantity of each steam generation are the same, the operation states of the liquid supply assembly, the heating assembly and the valve body are controlled to be the same in the process of each steam generation. According to the embodiment, the liquid supply assembly, the heating assembly and the valve body are controlled to circularly operate, the circulation times are the same as the steam release times, the fact that the steam parameters released by the steam generating device each time are the same can be guaranteed, the operation stability of the steam generating device is improved, and the situation that the steam generating device releases the steam with different parameters under the condition that the steam is released for many times is avoided.

As shown in fig. 5, in any of the above embodiments, the cyclic operation control of the valve body, the liquid supply assembly, and the heating assembly according to the number of vapor release times includes:

step 502, acquiring a first cycle corresponding to the valve body, a second cycle corresponding to the liquid supply assembly and a third cycle corresponding to the heating assembly according to the steam generation instruction;
