[0023] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0024] See also Figure 1 , Figure 1 1 is an application scenario diagram of a control method provided in an embodiment of the present application. The application scenario provided in the present application includes a steam device 100.

[0025] The steam device 100 may be an electrical appliance for generating steam, including but not limited to a steam hanging iron, a steam iron, a steam mop, a steam cleaning machine, a steam oven, and the like.

[0026] Take the Garment Steamer as an example. The Garment Steamer is a household appliance that removes wrinkles from clothes by generating high-temperature steam, while also sterilizing and deodorizing. Compared with traditional irons, the Garment Steamer is easier to operate and causes less damage to clothes. It is particularly suitable for quickly processing various types of clothes. The following is a detailed introduction to the Garment Steamer:

[0027] (1) Working principle:

[0028] Water tank: The user adds clean water to the water tank of the garment steamer. Heating system: The water in the water tank is heated to boiling, generating high-temperature steam. Steam nozzle (steam head): The generated steam is transported to the nozzle of the handheld part through a hose. Steam jet: The user sprays high-temperature steam directly onto the clothes through the nozzle, using the heat and humidity of the steam to soften the clothing fibers and remove wrinkles.

[0029] (2) Main features:

[0030] Easy to operate: You don't need to lay the clothes flat like traditional irons, you can hang them directly on the hanger for ironing. Wide range of applications: Suitable for a variety of fabrics, including cotton, linen, silk, wool, etc. High-efficiency wrinkle removal: High-temperature steam can quickly remove wrinkles on clothes. Sterilization and deodorization: High-temperature steam has the effect of sterilization and deodorization, which can clean clothes. Compact size: Easy to store and carry, suitable for home use or travel.

[0031] (3) Usage:

[0032] Add water: Open the water tank cap and add an appropriate amount of clean water, being careful not to exceed the maximum water level. Preheat: Plug in the power supply, turn on the switch, and wait a few minutes for the machine to preheat. Adjust the settings: Choose the appropriate amount of steam and temperature according to the material of the clothes. Hang the clothes: Hang the clothes on the hanger and make sure the clothes are flat. Start ironing: Hold the nozzle and spray steam evenly from top to bottom, moving the nozzle to cover the entire surface of the clothes. Turn off and clean: After ironing, turn off the power supply, wait for the machine to cool down, pour out the remaining water, and clean the nozzle and water tank.

[0033] The steam device 100 includes a steam generating device 10. The steam generating device 10 is used to generate steam. For example, the steam generating device 10 can be a boiler, in which a proper amount of water is placed, and the boiler is heated to generate steam.

[0034] The steam generating device 10 includes a body 11 and a water supply valve 12. The water supply valve 12 is disposed on the body 11 (such as a boiler body), and is used to control the amount of water flowing into the body 11.

[0035] Optionally, the opening of the water supply valve 12 can vary within a preset opening range, such as the water supply valve 12 is a solenoid valve, an electronic expansion valve, etc. The larger the opening of the water supply valve 12, the greater the amount of water flowing into the body 11 through the water supply valve 12.

[0036] Optionally, the water replenishment valve 12 can be switched between an open state and a closed state.

[0037] In some embodiments, the steam device 100 further includes a water tank 20 and a water pump 30. The water tank 20, the water pump 30 and the water supply valve 12 are connected in sequence. The water tank 20 is used to store water, and the water pump 30 is used to pump water to transport the water in the water tank 20 to the water supply valve 12. When the water supply valve 12 is opened, the water can be transported to the body 11.

[0038] In some embodiments, the steam device 100 further includes a temperature detection device 40. The temperature detection device 40 is used to detect the temperature of the body 11, such as detecting the bottom wall temperature and the side wall temperature of the body 11.

[0039] Optionally, the temperature detection device 40 may be a NTC (Negative Temperature Coefficient) thermistor, an infrared temperature measuring device, or the like.

[0040] Among them, the working principle of NTC thermistor is based on the characteristics of semiconductor materials. Common NTC thermistor materials include metal oxides such as manganese, cobalt, nickel, and iron. The resistivity of these materials decreases as the temperature increases. By detecting the resistance value of the NTC thermistor, the detection temperature can be detected.

[0041] Among them, infrared temperature sensors are non-contact temperature measuring devices that determine the surface temperature of an object by detecting the infrared radiation emitted by the object, such as by detecting the infrared radiation emitted by the body 11 to determine the temperature of the bottom wall and side walls of the body.

[0042] In some embodiments, the steam device 100 also includes an ironing head 50 and a steam valve 60. The ironing head 50, the steam valve 60 and the output port of the steam generating device 10 are connected in sequence. The ironing head 50 heats the water vapor output by the steam generating device 10 and outputs steam. The steam valve 60 is used to control the on and off of the steam generating device 10 and the ironing head 50.

[0043] The steam generated by the steam generating device 10 may be mixed with water, that is, a water-steam mixture is generated. In the steam device 100, generally, only steam needs to be ejected in the end, so the water-steam mixture needs to be heated again so that the ironing head 50 can finally output steam.

[0044] The iron head 50 can flexibly control the timing of steam spraying through the steam valve 60, so that steam can be sprayed when needed, thereby improving the flexibility of steam control.

[0045] In some embodiments, the steam generating device 10 further includes a heating device 70. The heating device 70 can heat the body 11, so that the water in the body 11 boils and generates steam. For example, the heating device 70 can be a resistance heating device 70.

[0046] Optionally, when the temperature of the main body 11 is low and not conducive to generating steam, the heating device 70 will work to heat, and when the temperature of the main body 11 is high and there is a risk of overheating, it will stop working, so that the temperature inside the main body 11 can quickly generate steam while avoiding overheating problems.

[0047] In some embodiments, a water level detection device 80 (such as a water level gauge) may also be provided in the body 11, and the water level detection device 80 is used to detect whether the water level has reached a preset water level. If the water level detection device 80 is provided at a first water level (such as a high water level) position of the body 11, it can detect whether the water level has reached a high water level; if the water level detection device 80 is provided at a second water level (such as a low water level, the second water level is lower than the first water level, such as the first water level is 50% water level and the second water level is 10% water level) position of the body 11, it can detect whether the water level has reached a low water level.

[0048] Alternatively, the water level detection device 80 may include multiple ones, which are respectively set at the high water level and the low water level, so that it can detect whether the water level in the main body 11 is lower than the low water level or higher than the high water level, thereby assisting the water replenishment control strategy in making decisions. For example, when the water level is greater than the first water level, the water replenishment valve 12 is controlled to be closed, that is, when the water level is too high, the water replenishment is stopped to avoid excessive water volume and reduce the steam generation speed; and / or when the water level is lower than the second water level, the water replenishment valve 12 is controlled to be opened, and when the water volume is too low, water replenishment is required to avoid dry burning and damage to the steam generating device 10.

[0049] Optionally, the water level detection device 80 may also be a device capable of detecting a precise water level. If the water level is within the detection range, the precise water level can be accurately detected.

[0050] Optionally, the water level detection device 80 includes but is not limited to a conductive probe, a float switch, a pressure sensor, an ultrasonic sensor, a capacitive sensor, a laser rangefinder, etc.

[0051] Among them, the conductive probe determines the water level by detecting the conductivity of water. When the water level reaches the probe position, the circuit is closed and an electrical signal is generated. It has a simple structure and low cost.

[0052] The float switch uses a floating ball to trigger the switch as the water level rises or falls. When the water level reaches a preset height, the change in the position of the float triggers a mechanical switch, which generates an electrical signal.

[0053] The pressure sensor calculates the height of the water by measuring the pressure at the bottom. The static pressure generated by the water column is proportional to the water level.

[0054] The ultrasonic sensor emits an ultrasonic pulse and measures the time it takes for it to reflect back. Based on the time difference and the speed of sound, the height of the water level can be calculated.

[0055] Capacitive sensors determine water level by measuring changes in capacitance. When the water level changes, the capacitance between the electrodes changes.

[0056] Laser rangefinders determine distance by emitting a laser pulse and measuring the time it takes for it to reflect back. Combined with known vessel geometry, the water level can be calculated.

[0057] Based on the introduction of the above-mentioned related scenarios, the embodiment of the present application provides a control method for steam equipment, and the control method is described in detail below:

[0058] See also Figure 2 A control method provided in an embodiment of the present application is implemented by step 011 to step 012, which is described in detail below.

[0059] Step 011: Obtain the detected temperature of the steam generating device.

[0060] The detection temperature can be determined by temperature information collected by a temperature detection device disposed on the body, such as the temperature of the bottom wall of the body detected in real time as the detection temperature.

[0061] Step 012: Based on the detected temperature, the steam generating device is heated and controlled so that the pressure of the steam generating device is within a preset pressure range and the detected temperature is within a preset temperature range.

[0062] Specifically, when the steam generating device is working, it will be heated. As the water temperature in the body gradually rises until it boils, steam begins to be generated. The pressure in the body gradually increases with the generation of water vapor. As the temperature continues to rise, the pressure will also increase. It can be seen that there is a corresponding relationship between pressure and temperature. By controlling the temperature of the body, the pressure control of the body can be indirectly achieved.

[0063] Optionally, when the detected temperature is within the preset temperature range, the pressure is within the preset pressure range. That is to say, by controlling the detected temperature within the preset temperature range, the pressure of the body can be indirectly controlled to be within the preset pressure range. When the pressure of the steam generating device is within the preset pressure range, the spray distance of the steam output by the steam generating device is greater than or equal to 0.5 meters, and high-pressure steam can be achieved. High-pressure steam has strong penetrating power and good wrinkle removal effect for ironing clothes.

[0064] Therefore, based on the detected temperature, the steam generating device may be heated and controlled so that the pressure of the steam generating device is within a preset pressure range and the detected temperature is within a preset temperature range.

[0065] See also Figure 3 Optionally, step 012: Based on the detected temperature, heating control of the steam generating device includes:

[0066] Step 0121: If the detected temperature is less than the first temperature threshold, the steam generating device is controlled to start heating;

[0067] Step 0122: If the detected temperature is greater than the second temperature threshold, the steam generating device is controlled to stop heating.

[0068] Among them, see Figure 4 , the first temperature threshold (such as Figure 4 Tmin in) and the second temperature threshold (such as Figure 4 The Tmax in the figure are all empirical values, which can be obtained by calibration in advance through experiments.

[0069] It is understandable that due to the uneven heat distribution when the body is heated, the temperature may continue to rise slowly after the heating is stopped until it reaches a peak temperature (such as Figure 4Therefore, when the detected temperature of the steam generating device is between the first temperature threshold and the reasonable peak temperature (which is an empirical value, such as less than or equal to Figure 4 In the case of the Text in the text), the temperature and pressure of the steam generating device are relatively appropriate. The peak temperature of the body can be ensured to be less than or equal to the reasonable peak temperature by reasonably setting the second temperature threshold.

[0070] Specifically, when the detected temperature is lower than the first temperature threshold, in order to avoid further temperature drop and affect the steam generation speed and pressure, the steam generating device is controlled to start heating to increase the temperature and maintain an appropriate pressure; when the detected temperature is higher than the second temperature threshold, in order to avoid the subsequent peak temperature being too high (such as higher than a reasonable peak temperature), the steam generating device is controlled to stop heating.

[0071] See also Figure 5 Optionally, step 012: heating and controlling the steam generating device based on the detected temperature, further includes:

[0072] Step 0123: When the steam valve is in an open state, if the detected temperature is less than a third temperature threshold, the steam generating device is controlled to start heating, and the third temperature threshold is greater than the second temperature threshold;

[0073] Step 0124: When the steam valve is in an open state, if the detected temperature is greater than a third temperature threshold, the steam generating device is controlled to stop heating.

[0074] Specifically, when a user uses the iron to iron clothes, steam is continuously ejected, which causes the pressure inside the main body to drop. In order to maintain the pressure inside the main body, a higher steam generation speed is required.

[0075] Therefore, when the steam valve is opened, the steam is lost at this time, and the threshold temperature of the heating control is raised (that is, the heating control is performed at a third temperature threshold greater than the second temperature threshold), that is, as long as the detected temperature is less than the third temperature threshold (such as Figure 4 The steam generating device is controlled to start heating, and the heating is stopped when the detected temperature is greater than or equal to the third temperature threshold.

[0076] In this way, the main body can be kept at a higher temperature, thereby offsetting the impact of the opening of the steam valve on the pressure and temperature of the main body, ensuring the speed and stability of steam generation during user use.

[0077] Optionally, the steam generating device can operate in a first steam mode and a second steam mode, and the amount of steam sprayed in the first steam mode is less than the amount of steam sprayed in the second steam mode;

[0078] For the steam stage, a temperature threshold (such as the first temperature threshold, the second temperature threshold or the third temperature threshold) for heating control of the steam generating device in the first steam mode is lower than a temperature threshold for heating control of the steam generating device in the second steam mode.

[0079] Optionally, when the steam generating device operates in the first steam mode, the second temperature threshold is in the interval [138 degrees Celsius, 176 degrees Celsius], and the first temperature threshold is in the interval [175 degrees Celsius, 195 degrees Celsius];

[0080] When the steam generating device operates in the second steam mode, the second temperature threshold is located in the interval [164 degrees Celsius, 187 degrees Celsius], and the first temperature threshold is located in the interval [175 degrees Celsius, 195 degrees Celsius].

[0081] The control method of the steam equipment provided in the embodiment of the present application is based on the relationship between the detected temperature of the steam generating device and the real-time pressure of the steam generating device. The temperature and pressure of the steam generating device are controlled by the detected temperature of the steam generating device, so that the temperature and pressure of the steam generating device are maintained within an appropriate range, which not only ensures safety but also ensures the steam generation speed and stability. There is no need to set a pressure gauge, which can save costs.

[0082] See also Figure 4 In order to ensure the stable execution of the heating and water replenishment control logic, this application sets multiple control parameters to assist the execution of the heating and water replenishment control logic. These control parameters are explained below:

[0083] (1) Tmin (corresponding to the first temperature threshold): The temperature threshold at which the boiler starts heating. When the boiler temperature is on a downward trend and is lower than this temperature, the boiler starts heating.

[0084] (2) Tmax (corresponding to the second temperature threshold): the temperature threshold at which the boiler stops heating. When the boiler temperature is on an upward trend and is greater than this temperature, the boiler stops heating.

[0085] (3) Text (corresponding to the third temperature threshold): The temperature peak threshold when the boiler is heated. When this threshold is exceeded, the second water replenishment strategy is executed. When the boiler starts heating from Tmin and stops heating at Tmax, the peak temperature is different due to the influence of the water level in the boiler. When the water level in the boiler is higher, the temperature of the heating body will transfer enough heat to the water in the boiler, and the peak temperature will be lower. Conversely, the lower the water level in the boiler, the higher the peak temperature.

[0086] In actual implementation, based on the setting of the water level meter, the above water level may not be accurately detected, and the peak temperature corresponding to the average value of the second water level range corresponding to the second water replenishment strategy may be used as the third temperature threshold.

[0087] (4) Tb: indicates the detected temperature of the boiler.

[0088] (5) Thi (corresponding to the sixth temperature threshold): The boiler ultra-high temperature threshold. When this threshold is exceeded, the first water replenishment strategy is executed. When the boiler temperature reaches this value, it indicates that the boiler is in an extremely low water level or dry burning state, and sufficient water needs to be added to the boiler.

[0089] (6) Steam valve single opening time: indicates the time the solenoid valve is continuously opened for a single time. If the solenoid valve is closed, the single opening time is reset to zero.

[0090] (7) Cumulative opening time of steam valve: indicates the time that the solenoid valve is continuously opened for multiple times. After water replenishment occurs, the value is reset to zero.

[0091] (8) Cumulative closing time of steam valve: During the interval between two water replenishments, the closing time of the solenoid valve is counted. After water replenishment occurs, the value is reset to zero.

[0092] See also Figure 6 In some embodiments, the control method further comprises:

[0093] Step 013: Preheat the steam generating device.

[0094] Specifically, before the steam device performs heating control, the body may be preheated to ensure a heating effect.

[0095] See also Figure 7 Optionally, step 013 includes:

[0096] Step 0131: When the detected temperature is less than the fifth temperature threshold, controlling the steam generating device to start heating;

[0097] Step 0132: When the detected temperature is greater than a sixth temperature threshold, controlling the steam generating device to stop heating;

[0098] Step 0133: After stopping heating, if the detected temperature reaches the peak temperature and then stops rising and continues for a first preset time period, it is determined that the preheating is completed.

[0099] Specifically, preheating generally includes preheating under cold engine start-up and preheating under hot engine start-up.

[0100] For cold machine startup, the overall temperature of the steam equipment is close to room temperature. Since the temperature is lower than the fifth temperature threshold, heating is turned on. During preheating, the temperature starts to rise. When the temperature reaches or exceeds the sixth temperature threshold, heating is stopped.

[0101] The fifth temperature threshold and the sixth temperature threshold may be the same or different. For example, the fifth temperature threshold and the sixth temperature threshold are the same (both are Tmax).

[0102] Optionally, for the preheating stage, a temperature threshold (such as the fifth temperature threshold or the sixth temperature threshold) for preheating control of the steam generating device in the first steam mode is lower than a temperature threshold for preheating control of the steam generating device in the second steam mode.

[0103] When the temperature is less than Tmax, the boiler continues to heat until the temperature exceeds Tmax, then stops heating. At this time, due to the uneven thermal distribution of the boiler, the boiler temperature will still rise slowly until it reaches a peak temperature Tpeak. After detecting Tpeak, if the temperature does not rise within ⊿T time (i.e. the first preset time), the boiler is considered to be preheated.

[0104] For the start-up of a thermal engine, the main body may have just finished working and the temperature itself may be greater than Tmax. Therefore, the steam generating device stops heating at this time and takes the temperature at startup as the peak temperature. If the temperature does not rise again within the monitored time of ⊿T, it is considered that the boiler preheating is completed.

[0105] Optionally, when the preheating time is greater than a second preset time length, the peak temperature is greater than a second temperature threshold, and the detected temperature is greater than a first temperature threshold, it is determined that the preheating is completed.

[0106] Specifically, in order to ensure that preheating does not take too long, an upper limit (i.e., a second preset duration) is set for the preheating time. When the preheating completion conditions in the previous embodiment cannot be met, if the preheating time reaches the second preset duration and the temperature reaches an acceptable level (i.e., the peak temperature is greater than the second temperature threshold, and the detected temperature is greater than the first temperature threshold), the preheating is also considered to be completed, thereby avoiding the situation where the heating to the peak temperature is too slow, and then monitoring the ⊿T time to determine whether the preheating is completed, which takes too long.

[0107] Optionally, the operation process of the steam generating device includes a preheating stage and a steam stage, the fifth temperature threshold for starting heating in the preheating stage is lower than the first temperature threshold for starting heating in the steam stage, and the sixth temperature threshold for starting heating in the preheating stage is lower than the second temperature threshold for starting heating in the steam stage.

[0108] In this way, by lowering the heating control threshold during the preheating stage, the preheating conditions can be completed more quickly, thereby increasing the preheating speed.

[0109] Optionally, the temperature when preheating is completed is within a preset temperature range.

[0110] In this way, the temperature when preheating is completed can reach the preset temperature range, and the pressure in the boiler can also reach the preset pressure range. When the pressure of the steam generating device is within the preset pressure range, the injection distance of the steam output by the steam generating device is greater than or equal to 0.5 meters, thereby achieving the output of high-pressure steam after preheating is completed.

[0111] Optionally, the preset temperature range includes a first temperature range and a second temperature range, the preset pressure range includes a first pressure range and a second pressure range, the first temperature range corresponds to the first pressure range, the second temperature range corresponds to the second pressure range, and the second pressure range is greater than the first pressure range;

[0112] A first preheating temperature at which the steam generating device is preheated in the first steam mode is lower than a second preheating temperature at which the steam generating device is preheated in the second steam mode. The first preheating temperature is within a first temperature range and the second preheating temperature is within a second temperature range.

[0113] Specifically, in view of the difference in steam requirements between the first steam mode and the second steam mode, for example, the first steam mode requires the steam injection distance to reach 0.5 meters, while the second steam mode requires the steam injection distance to reach 2 meters.

[0114] Therefore, the preset temperature range can be divided into a first temperature range and a second temperature range, the preset pressure range includes a first pressure range and a second pressure range, the first temperature range corresponds to the first pressure range, the second temperature range corresponds to the second pressure range, and the second pressure range is greater than the first pressure range.

[0115] Therefore, during preheating, the temperature at which preheating is completed is controlled based on the steam mode entered after the steam generating device is preheated, so that the temperature at which preheating is completed meets the requirements of the corresponding steam mode.

[0116] In this way, the first preheating temperature completed by the steam generating device in the first steam mode is within the first temperature range, so that the pressure in the boiler is within the first pressure range, thereby outputting steam with an injection distance of 0.5 meters; the second preheating temperature completed by the steam generating device in the second steam mode is within the second temperature range, so that the pressure in the boiler is within the second pressure range, thereby outputting steam with an injection distance of 2 meters.

[0117] It can be understood that the steam injection distance refers to the result of testing under specific preset scenarios, such as using a 2-meter-long dark curtain extending from the ironing head and the ironing panel along the steam injection direction, and when the steam equipment is preheated and enters the steam stage, the distance between the farthest position that the steam can reach and the ironing head is detected, thereby obtaining the steam injection distance.

[0118] See also Figure 8In some embodiments, the steam device further comprises an ironing head connected to an output port of the steam generating device, and the method further comprises:

[0119] Step 014: Based on the temperature of the ironing head, the ironing head is heated and controlled to heat the water vapor mixture output by the steam generating device to output steam.

[0120] Specifically, in order to avoid the risk of burns due to overheating of the iron, or the temperature being too low to heat the water vapor mixture output by the steam generating device into steam, the temperature of the iron needs to be controlled.

[0121] If the temperature of the iron head is lower than the fourth temperature threshold (ie the temperature of the iron head is too low), the iron head is controlled to start heating; if the temperature of the iron head is higher than the fifth temperature threshold (ie the temperature of the iron head is too high), the iron head is controlled to stop heating.

[0122] See also Fig. 9 In some embodiments, the steam device further comprises a water level meter and a water supply valve, the water level meter is used to detect the water level of the steam generating device, and the water supply valve is used to control the amount of water flowing into the input port of the steam generating device, and the method further comprises:

[0123] Step 015: Based on the detected temperature, the water supply valve is controlled to switch so that the water level in the steam generating device is within a preset water level range.

[0124] Specifically, when the steam generating device is working, the heating process is as follows:

[0125] First, the water temperature in the body gradually rises until it boils, at which point steam begins to be generated and the water level drops. When there is sufficient water, the maximum temperature that the body can reach is generally not too high. As the water is converted into steam and sprayed out of the iron head, the water gradually drains away, the water level drops, and the maximum temperature that the body can reach gradually rises. Therefore, based on the detected temperature in the body, the corresponding water level in the body can be determined.

[0126] Different water replenishment strategies can be preset for different water level ranges (ie, temperature ranges). The lower the water level, the greater the amount of water replenished by the corresponding water replenishment strategy.

[0127] Therefore, the current water level in the body can be judged based on the detected temperature, thereby determining the corresponding water replenishment strategy.

[0128] Among them, water replenishment is achieved by controlling the water pump and the water replenishment valve. The water replenishment strategy is the control strategy for the water replenishment valve. When the water replenishment valve is opened, the water pump operation needs to be controlled synchronously to replenish water.

[0129] The water level gauge can also detect the water level. When the water level is in different water level ranges, different degrees of water replenishment control can be performed, so that the water level in the steam generating device is within the preset water level range to ensure the steam generation speed.

[0130] See also Fig.10 Optionally, step 015 includes:

[0131] Step 0151: When the detected temperature is greater than the high-temperature water replenishment temperature threshold, the water replenishment valve is controlled based on the first water replenishment strategy;

[0132] Step 0152: When the detected temperature is greater than the circulating water replenishment temperature threshold, the water replenishment valve is controlled based on the second water replenishment strategy, the circulating water replenishment temperature threshold is less than the high-temperature water replenishment temperature threshold, and the water replenishment amount of the first water replenishment strategy is greater than the water replenishment amount of the second water replenishment strategy.

[0133] Specifically, when the detected temperature is greater than the high temperature water replenishment temperature threshold (such as Figure 4 In the Thi) case shown in the figure, the main body is in an ultra-high temperature state, and the main body is most likely in a dry burning or ultra-low water level (such as less than 5%) state. At this time, a large amount of water needs to be supplemented, so the first water replenishment strategy is used for water replenishment.

[0134] When the detected temperature is greater than the circulating water replenishment temperature threshold (the temperature is higher at this time, the water level is still lower than the second water level, but higher than the water level in the ultra-high temperature state (such as 5% to 10%)), the water replenishment amount will be relatively less, and the second water replenishment strategy will be used for water replenishment.

[0135] For example, high temperature water replenishment will be divided into two times, each time replenishing 15% of the water volume (or opening the steam valve for 35 seconds), and the interval of water replenishment is 15s, so that the body reaches the appropriate water level, that is, quickly replenishing 30% of the water volume. The cycle water replenishment is replenishing 5 times, each time replenishing 5% of the water volume (or opening the steam valve for 12 seconds), and the interval is 10 seconds (S), that is, replenishing 25% of the water volume in total.

[0136] When the detected temperature is lower than the circulating water replenishment temperature threshold and the water level is within the preset water level range, conventional water replenishment can be performed with a smaller amount of water to compensate for the steam loss from the ironing head, that is, water replenishment can be performed using the third water replenishment strategy.

[0137] Optionally, the amount of water added by the third water replenishment strategy can be a fixed value, which is the average amount of water output by the steam generating device. Alternatively, the amount of water added by the third water replenishment strategy can be dynamically determined based on the amount of water output by the steam generating device, such as the amount of water added by the third water replenishment strategy is always equal to the amount of water output by the steam generating device in real time.

[0138] For example, the opening time of the steam valve can be obtained, and the cumulative opening time between the last water replenishment and the current water replenishment can be calculated to determine the amount of water lost. The amount of water replenished by the third water replenishment strategy can be equal to the amount of water lost, thereby replenishing the lost water.

[0139] Optionally, the amount of water added by the third water replenishment strategy can be less than the amount of water lost. In this way, the water in the body maintains a slow loss trend, which can avoid that after each user uses the steam device, there is still a lot of water in the body, and the accumulation of water may cause water pollution, thereby affecting the user experience the next time. If the water level is always maintained at too high a level, the steam generation speed will also be reduced.

[0140] Please continue reading Fig.10 Optionally, step 015 further includes:

[0141] Step 0153: When the operating condition of the steam equipment meets the triggering condition of the third water replenishment strategy, the water replenishment valve is controlled based on the third water replenishment strategy; wherein the triggering condition of the third water replenishment strategy further includes at least one of the following:

[0142] The detected temperature is lower than the circulating water replenishment temperature threshold;

[0143] The cumulative opening time of the steam valve of the steam equipment is greater than the preset cumulative time;

[0144] The first water replenishment strategy or the second water replenishment strategy has been implemented;

[0145] The preheating time of the steam generating device is less than or equal to the preset preheating time;

[0146] Neither the first water replenishment strategy nor the second water replenishment strategy is executed, and the preheating time is longer than the preset preheating time.

[0147] In this way, through a variety of triggering methods, it can be combined into triggering conditions that meet the needs of different scenarios, and the process can be replenished with water in time to ensure the dynamic balance of water volume and the steam effect.

[0148] For example, when the detected temperature is less than the circulating water replenishment temperature threshold, the water level is relatively high, corresponding to the third water level range, and the target control strategy is determined to be the third water replenishment strategy.

[0149] For another example, the first water replenishment strategy or the second water replenishment strategy has been executed. At this time, since a large amount of water replenishment has been carried out, only a small amount of water replenishment is required.

[0150] For another example, if the preheating time of the steam generating device is less than or equal to the preset preheating time and the preheating is insufficient, the water consumption rate is slow, and water replenishment can be performed in the process at this time.

[0151] For another example, if neither the first water replenishment strategy nor the second water replenishment strategy is executed (that is, the temperature does not meet the requirements of the first water replenishment strategy or the circulating water replenishment), the preheating time is longer than the preset preheating time, and the cumulative opening time of the steam valve is longer than the preset cumulative time, then process water replenishment can be performed at this time.

[0152] In some embodiments, based on at least one of a single opening time of the steam valve, a detected temperature and an increase rate of the detected temperature, the water replenishment valve is controlled so that the water level is within a preset water level range.

[0153] The switching time of the steam valve includes the single opening time. When controlling the water replenishment valve, the single opening time of the steam valve can be considered. The longer the single opening time, the greater the amount of water replenishment (such as the more water replenishment times and / or the shorter the water replenishment interval); and the higher the detection temperature, the higher the pressure in the boiler, and the greater the amount of steam sprayed each time the steam valve is opened. Therefore, the higher the detection temperature, the greater the amount of water replenishment; similarly, the faster the detection temperature increases, the greater the heating power of the boiler (or the less water), and more water replenishment is needed at this time.

[0154] For example, when any one of the single opening time, the detection temperature, and the detection temperature growth rate meets the corresponding process water replenishment condition, the process water replenishment is performed. For example, water can be replenished at a fixed water replenishment amount, once, and the water replenishment time is 7 seconds (i.e., the steam valve is opened for 7 seconds). Alternatively, the water replenishment time or the number of water replenishment times can be dynamically adjusted based on the single opening time, the detection temperature, and the detection temperature growth rate.

[0155] For another example, when the single opening time of the steam valve, the detection temperature, and the increasing speed of the detection temperature all meet the corresponding water replenishment conditions, the process water replenishment is performed.

[0156] In the first steam mode, the water supply valve is controlled based on the cumulative opening time or the single opening time of the steam valve so that the water level is within a preset water level range;

[0157] In the second steam mode, the water replenishment valve is controlled based on the single opening time, the cumulative opening time and the cumulative interval time of the steam valve so that the water level is within the preset water level range.

[0158] It can be understood that for different steam modes, due to the difference in the amount of steam sprayed, the strategies for water replenishment are also different.

[0159] For the first steam mode with a smaller steam eruption volume, when the cumulative opening time or the single opening time of the steam valve meets the corresponding water replenishment condition, process water replenishment is performed.

[0160] For example, when the cumulative opening time of the steam valve is greater than the second preset time or the single opening time is greater than the third preset time, the water replenishment valve is controlled to open to replenish the first water volume;

[0161] It can be understood that for different triggering conditions when triggering the water replenishment process, the cumulative opening time or the single opening time that satisfies the corresponding water replenishment conditions is also different.

[0162] For example, the third water replenishment strategy is triggered after high-temperature water replenishment or circulating water replenishment occurs. At this time, the temperature in the boiler is high and water replenishment is needed in time. Therefore, the second preset time length or the third preset time length is shorter (such as 3 seconds); and when the process water replenishment is entered without high-temperature water replenishment or circulating water replenishment, the temperature in the boiler is lower and the water consumption is slower. Therefore, the second preset time length or the third preset time length is longer (such as 10 seconds or 20 seconds).

[0163] For the second steam mode with a larger steam eruption volume, water can be replenished in time, such as when any one of the single opening time, the cumulative opening time or the cumulative interval time meets the corresponding water replenishment conditions, water is replenished.

[0164] Alternatively, when the cumulative opening time meets the corresponding water replenishment conditions (such as greater than 20 seconds), the cumulative interval time can also be combined to accurately replenish water. The longer the cumulative interval time, the more water is replenished, and the shorter the cumulative interval time, the less water is replenished.

[0165] For example, when the cumulative opening time of the steam valve is greater than the fourth preset time and the cumulative interval time is less than the fifth preset time, the water replenishment valve is controlled to open to replenish the second water volume;

[0166] When the cumulative opening time of the steam valve is greater than the fourth preset time and the cumulative interval time is greater than or equal to the fifth preset time, the water replenishment valve is controlled to open to replenish the third water volume, and the third water volume, the second water volume and the first water volume decrease in sequence.

[0167] It is understandable that for process water replenishment, the amount of water replenished each time is small, and generally only one replenishment is performed. For example, if water is replenished once, the replenishment time is 7 seconds.

[0168] Optionally, the amount of water replenished each time in the third water replenishment strategy is less than the amount of water consumed by the steam generator.

[0169] The amount of water added can be less than the amount of water lost. In this way, the water in the body maintains a slow loss trend, which can avoid that after each user uses the steam device, there is still a lot of water in the body, and the accumulation of water may cause water pollution, thus affecting the user experience the next time. If the water level is always maintained at too high a level, it will also reduce the steam generation speed.

[0170] Alternatively, the amount of water lost may be calculated based on a single opening time of the steam valve, so that the amount of water replenished is equal to the amount of water lost.

[0171] For example, the amount of water replenished each time in the third water replenishment strategy is positively correlated with the cumulative opening time.

[0172] In addition to replenishing water based on the single opening time of the steam valve, water replenishment can also be performed based on the accumulated opening time of the steam valve.

[0173] In some embodiments, the water replenishment amount of the steam generating device in the first steam mode is less than the water replenishment amount of the steam generating device in the second steam mode.

[0174] It can be understood that since the amount of steam output by the first steam mode is less than the amount of steam output by the second steam mode, in order to avoid too high water level in the boiler, the water replenishment amount of the first steam mode and the second steam mode needs to be adaptively set so that the water replenishment amount of the first steam mode is less than the water replenishment amount of the second steam mode.

[0175] For example, when executing any water replenishment strategy (such as the first water replenishment strategy, the second water replenishment strategy, or the third water replenishment strategy), the water replenishment amount of the first steam mode is less than the water replenishment amount of the second steam mode.

[0176] In some embodiments, the operation process of the steam generating device includes a preheating stage and a steam stage, and the water replenishment amount in the preheating stage is less than the water replenishment amount in the steam stage.

[0177] It is understandable that water needs to be replenished in both the preheating stage and the steam stage. In order to complete the preheating as quickly as possible, the water replenishment in the preheating stage can be set to be smaller than the water replenishment in the steam stage. In this way, the water level in the preheating stage is lower while ensuring that dry burning will not damage the boiler, which can increase the temperature rise rate and thus improve the preheating efficiency.

[0178] For example, when executing any water replenishment strategy (such as the first water replenishment strategy, the second water replenishment strategy or the third water replenishment strategy), the water replenishment amount in the preheating stage is less than the water replenishment amount in the steam stage.

[0179] In some embodiments, the steam equipment also includes an ironing head, a display panel and a controller. The controller can perform temperature fault detection based on the detected temperature and the water level of the steam generating device; and / or perform preheating fault detection based on the preheating time, the detected temperature and the temperature of the ironing head; and perform communication fault detection based on the communication data between the controller and the display panel.

[0180] Specifically, in order to ensure the operational stability of the steam equipment, the steam equipment can also perform fault self-detection.

[0181] The faults mainly include temperature faults, preheating faults and communication faults.

[0182] Among them, temperature faults include high temperature and high water level faults of the main body and abnormally high temperature faults. In the case of a steam valve failure and blockage, the steam valve is controlled to open, but it is not actually opened. Due to the regular water replenishment, the water level continues to rise. At this time, the main body is closed, and the temperature will continue to rise with the heating, resulting in a high temperature and high water level fault. Normally, under high temperature conditions, the water level is generally low. Therefore, when it is detected that the detection temperature is greater than the sixth temperature threshold and the water level is greater than the high water level (such as 50%), a high temperature and high water level fault can be determined. When the temperature inside the main body is abnormally high, there is also a safety risk. For example, if the detection temperature is greater than the sixth temperature threshold and lasts for a long time; or the detection temperature reaches the maximum safe temperature, it can be considered an abnormally high temperature fault.

[0183] In this way, through temperature fault detection, the temperature of the main body is ensured to be always within a safe range, ensuring the safety of the steam equipment.

[0184] Among them, the preheating failure is mainly a failure in the preheating process. When the preheating time is too long (such as greater than the second preset time), the judgment condition for preheating completion is still not met, and the detected temperature is still low, such as lower than the first temperature threshold, it can be determined that the preheating has failed. There may be a preheating failure. At this time, normal heating may not be possible, or the temperature detection device may fail, which may result in the inability to achieve subsequent heating control, posing a safety risk.

[0185] In this way, by preheating fault detection, safety risks can be eliminated before users actually use the product, further improving safety.

[0186] The display panel is located above the iron head and is responsible for the mode button selection and display, the steam button (controls the opening and closing of the steam valve), and the detection of the temperature of the iron head; the controller is located inside the steam generator and is responsible for the control of the boiler, water pump, water supply valve and iron head. The display panel and the controller are connected by a single-line serial port.

[0187] Communication failure is a failure in which the communication between the display panel and the controller is disconnected. If the controller does not receive feedback within the preset time after sending the iron control command, it will be determined that there is a communication failure. In the case of a communication failure, the iron control fails, and the steam equipment cannot be used normally. Therefore, it needs to be sent for repair as soon as possible.

[0188] When at least one of a temperature failure, a preheating failure, and a communication failure is detected, the steam device may send out a prompt message to remind the user to send the device for repair as soon as possible to ensure the safety of using the steam device.
