Abstract
Description
Technical Field
[0001] This invention relates to the field of household appliances, and more particularly to a control method for a steam generator and a steam generator. Background Technology
[0002] Based on energy conservation calculations and the actual operation of existing products, it is known that non-boiler-type garment steamers have relatively low steam output, which cannot adequately meet the application needs when ironing heavy clothing and down jackets. To achieve good ironing results, repeated ironing is required, which is not only time-consuming but may also lead to excessive moisture in the clothing, making it unwearable immediately after ironing. Therefore, when ironing heavy clothing, garment steamers need to provide a large volume of steam.
[0003] Currently, the method for generating large amounts of steam in garment steamers is to heat water in a steam boiler to produce steam, which is then stored in the boiler. Once a certain pressure is reached, the steam is released through a solenoid valve. However, pressure boilers pose significant safety hazards in their design and application. When a large amount of scale accumulates inside, it increases the thermal resistance, thereby affecting the temperature sensitivity and posing an explosion risk. Summary of the Invention

[0054] Based on energy conservation calculations and the actual operation of existing products, it is known that non-boiler-type garment steamers have relatively low steam output, which cannot adequately meet the application needs when ironing heavy clothing and down jackets. To achieve a good ironing effect, repeated ironing is required, which is not only time-consuming but may also lead to excessive moisture in the clothing, making it unwearable immediately after ironing. Therefore, when ironing heavy clothing, garment steamers need to provide a large amount of steam. Currently, the method for generating large amounts of steam in garment steamers is to heat water in a steam boiler to produce steam, store it in the boiler, and then release the steam through a valve after reaching a certain pressure. However, pressure boilers have significant safety hazards in their design and application. When a large amount of scale accumulates inside, it increases the thermal resistance, thereby affecting the temperature sensitivity and posing an explosion risk.
[0055] To solve the above problems, the present invention provides a control method for a steam generating device 100, the steam generating device 100 including a steam generator 1, a heater disposed in the steam generator 1, a water supply system 2 for supplying water to the heater, and a temperature detection system 3 for monitoring the temperature of the heater.
[0056] The steam generating device can be a steam mop, a garment steamer, or an iron. This solution is not limited to protecting only the above-mentioned electrical appliances, but can also protect all products that generate steam. For ease of description, the following explanation uses a garment steamer and its ironing head as examples.
[0057] Based on the steam generating device 100 described above, in the first embodiment of the present invention, as follows: Figure 1 The control method for the steam generator 100 includes:
[0058] Step S10: Obtain the temperature value of the heater detected by the temperature detection system 3;
[0059] Step S20: When the temperature of the heater reaches the first set value, control the water supply system 2 to spray water onto the heater.
[0060] In the technical solution of this invention, the control method of the steam generating device 100 includes: acquiring the temperature value of the heater detected by the temperature detection system 3; when the temperature value of the heater reaches a first set value, controlling the water supply system 2 to spray water onto the heater. Because this solution first uses dry burning of the heater, the heating surface and power of the heater are greater than those of conventional heaters, but the power of the heater does not exceed the rated power value. When the set temperature is reached, a certain amount of water is sprayed. Due to the increased heating surface, the amount of steam generated by the heater increases, thus producing a large amount of steam. Compared with existing technologies, this is safer than storing a large amount of steam at a certain pressure, and also produces much more steam than simply spraying water onto the existing heater 11. Furthermore, since the steamer head of the garment steamer is a secondary heating of steam, the enthalpy of the steam is relatively low, therefore the energy required for heating it is extremely low, resulting in the steamer head heater being in an off state most of the time during operation. To better utilize this energy, the heating surface and power of the heater are increased based on the existing steam generator. The steam heater 41 of the iron is disconnected to store heat. When the temperature of the heater reaches the set value, a large flow of water is instantly introduced into the heater. At this time, the energy stored in the heater heats it instantly, thereby generating instantaneous explosive steam, which is sprayed onto the clothes to smooth out the wrinkles.
[0061] It should be noted that the heater described in this solution can be an electric heater. An electric heater is a device that consumes electrical energy and converts it into heat energy to heat the material that needs to be heated. During operation, the low-temperature fluid medium enters the inlet under pressure through the pipeline. The heat exchange channels inside the electric heating container, designed using the principles of fluid thermodynamics, carry away the high-temperature heat energy generated during the operation of the electric heating element, thereby increasing the temperature of the heated medium. Of course, this solution is not limited to electric heaters; other types of heaters can also be used, such as electromagnetic heaters, resistance heaters, or infrared heaters.
[0062] In a second embodiment of the present invention, the heater includes a main heater 11 and an auxiliary heater 12, the water supply system 2 supplies water to the main heater 11 and the auxiliary heater 12, and the temperature detection system 3 monitors the temperature of the main heater 11 and the auxiliary heater 12. Figure 2 As shown, it is similar to Figure 1 The difference in the embodiments is that step S10 includes:
[0063] Step S10a: Obtain the temperature value of the main heater detected by the temperature detection system;
[0064] Step S20 includes:
[0065] Step S20a: Obtain the temperature value of the auxiliary heater detected by the temperature detection system.
[0066] The main heater 11 can be configured as a heater with the same power and heating surface as the prior art. By adding the auxiliary heater 12 to the existing steam generator, the heating surface of the heater is increased and the heating power is increased. When the temperatures of the main heater 11 and the auxiliary heater 12 both reach the set value, a large flow of water is sprayed onto the main heater 11 and the auxiliary heater 12 at the same time. At this time, the water vapor vaporized by the auxiliary heater 12 and the water vapor vaporized by the main heater 11 work together to form a larger amount of steam, i.e., explosive steam.
[0067] It should be noted that there may be one or more auxiliary heaters 12. When multiple auxiliary heaters 12 are provided, the larger number and faster heating rate result in a greater amount of steam being generated when water is sprayed onto the auxiliary heaters 12. The number and power of the auxiliary heaters 12 can be selected according to the actual situation, but should not exceed the rated power.
[0068] In the third embodiment of the present invention, as Figure 3 As shown, it is similar to Figure 1 The difference in the embodiments is that: after step S20a, the following is included:
[0069] Step S30: When the temperature values of the main heater 11 and the auxiliary heater 12 are lower than the first set value, control the water supply system 2 to adjust the spray volume.
[0070] Because the temperature of the main heater 11 and the auxiliary heater 12 will gradually decrease after water is sprayed onto them, it is understandable that if the amount of water sprayed remains the same as before, the main heater 11 and the auxiliary heater 12 cannot completely and quickly vaporize all the water. This will cause water droplets to spray out during ironing, affecting the ironing quality. Based on the temperature of the main heater 11 and the auxiliary heater 12, the amount of water sprayed by the water supply system 2 is adjusted to ensure that all the water sprayed onto the main heater 11 and the auxiliary heater 12 can be completely vaporized.
[0071] In a specific embodiment of the present invention, the range of the first set value is greater than or equal to 170°C and less than or equal to 200°C. This can ensure the conditions for generating a large amount of steam required, and also make the user experience very good. There will be no defects such as steam interruption or excessive waiting time due to the long time required for heating.
[0072] In a fourth embodiment of the present invention, the steam generating device 100 further includes an ironing head 4 for heating the steam generated by the steam generator 1, and a steam heater 41 disposed within the ironing head 4. The ironing head 4 may be integrally disposed with the steam generator 1 or separately disposed from the steam generator 1. The steam is delivered to the ironing head 4, and the steam heater 41 heats the steam, as detailed in subsequent sections. In one embodiment of the present invention, as... Figure 4 As shown, it is similar to Figure 1 The difference in the embodiments is that: after step S20a, the following is included:
[0073] S40. When the temperature value of the auxiliary heater 12 reaches the first set value, the auxiliary heater 12 is controlled to stop heating, and the steam heater 41 is controlled to heat.
[0074] During the power design process, the total power of the three heaters can be kept below the rated power; alternatively, the sum of the power of the main heater 11 and the steam heater 41, or the main heater 11 and the auxiliary heater 12, can be kept below the rated power. Program control ensures that the auxiliary heater 12 and the steam heater 41 do not operate simultaneously. In practice, after startup, the main heater 11 and the auxiliary heater 12 begin heating, while the steam heater 41 remains inactive. When the main heater 11 and the auxiliary heater 12 reach the first set value, the auxiliary heater 12 stops heating, and the steam heater 41 begins heating to preheat the generated steam. During the continuous operation of the steam generator 100, the main heater 11 provides stable steam, and the steam heater 41 continuously heats the steam.
[0075] In the fifth embodiment of the present invention, after step S20a, the control method of the steam generator 100 includes:
[0076] Step S50: Control the steam heater 41 to stop working;
[0077] In practice, when an operator finishes ironing a portion of clothing and needs to fold and change the garment, and does not require steam for a short period, the operator can turn off the ironing head switch, thus stopping the steam heater 41 from working and preventing the consumption of the generated steam. In this case, the operator will need to store energy for the main heater 11 and the auxiliary heater 12 when a large amount of steam is needed next time. If the operator no longer needs to use steam for work, the main switch can be turned off to stop the heating of the main heater 11 and the auxiliary heater 12.
[0078] Step S60: If the temperature value of the main heater 11 is greater than or equal to the second set value, control the water supply system 2 to stop spraying water, and control the main heater 11 and the auxiliary heater 12 to heat.
[0079] In practice, when a user uses steam, the temperatures of the main heater 11 and the auxiliary heater 12 gradually decrease during the water spraying process. However, because the main heater 11 continues to be powered on, it eventually reaches a stable temperature. When the temperature of the main heater 11 drops to another set value, namely the second set value, such as 130°C, the system will adjust to a stable operating state. At this time, the garment steamer system will enter a stable state of continuous steam spraying, producing continuous and stable steam. If the heater temperature has not yet dropped to the other set value, such as 130°C, and the user has stopped using the steam (meaning the user is not using the steamer head for ironing), the system will enter a preheating state, and the steam heater 41 will stop heating. If the operator no longer needs to use steam for work, the switch is turned off, and the temperature of the main heater 11 and the auxiliary heater 12 will drop, indicating that there is no need to store heat energy for the next steam generation. However, when the temperature of the main heater 11 is greater than or equal to the second set value, it indicates that the user will continue to use the steam generator 100. At this time, the main heater 11 and the auxiliary heater 12 are controlled to continue heating, so that a burst of steam, i.e., explosive steam, can be generated in the next cycle.
[0080] In a specific embodiment of the present invention, the range of the second set value is greater than or equal to 120°C and less than or equal to 145°C. When the user uses steam and causes the heater temperature to drop to another set value, such as 130°C, the steam generating device 100 will adjust to a stable operating state. At this time, the garment steamer system will enter a continuous operating state, that is, generate continuous and stable steam. If the heater temperature has not dropped to another set value, such as 130°C, and the user has stopped using steam, the system will enter a heater preheating state, that is, the main heater 11 and the auxiliary heater 12 will be dry-burned again to store energy for the next generation of explosive steam.
[0081] The present invention also provides a steam generating device 100, please refer to [link to relevant documentation]. Figure 5 The steam generating device 100 includes a steam generator 1, a water supply system 2, a temperature detection system 3, and a control device. The steam generator 1 forms a steam chamber, and a heater is installed inside the steam chamber.
[0082] The water supply system 2 is used to spray water onto the heater to generate steam, that is, when the heater is heated to a temperature that can vaporize water, the water supply system 2 sprays water onto the heater.
[0083] The temperature detection system 3 is used to detect the temperature of the heater, and the temperature detection system 3 determines when the water supply system 2 needs to spray water based on the measured temperature.
[0084] The control device is electrically connected to the temperature detection system 3, the heater and the water supply system 2. The control device is used to control the water supply system 2 to spray water onto the heater when the heater reaches a first set value.
[0085] In the technical solution of this invention, by dry-burning the heater, when setting the power and heating area of the heater, its heating surface and heating power are larger than the heating surface of heaters in general prior art, but the power of the heater is set to not exceed the rated power value. Because the heating surface of the heater is increased, the amount of steam generated by the heater is increased compared with the prior art. When the temperature of the heater reaches the set value, a larger flow rate of water than that of the prior art is instantaneously introduced into the heater. At this time, the energy stored in the increased heating surface of the heater will vaporize the increased amount of water, thereby increasing the amount of steam generated, that is, generating explosive steam.
[0086] Furthermore, compared to existing technologies, simply increasing the power, size, or preset value of the main heater 11 would prolong the dry-burning time, or during normal ironing, when water is continuously sprayed onto the main heater 11, the main heater 11 might not reach the set temperature value in a short time, resulting in steam interruption. In this embodiment, the heater includes a main heater and an auxiliary heater. The water supply system is used to spray water onto the main heater and the auxiliary heater to generate steam. The temperature detection system is used to detect the temperature of the main heater and the auxiliary heater. The control device is electrically connected to the main heater and the auxiliary heater, and the control device is used to control the water supply system to spray water onto the main heater and the auxiliary heater when the main heater and the auxiliary heater reach the first preset value. By dry-heating the main heater 11 and the auxiliary heater 12, a certain amount of water is sprayed when the set temperature is reached, causing the main heater 11 and the auxiliary heater 12 to simultaneously generate a large amount of steam. Therefore, by adding an auxiliary heater 12, the heating rate can keep up with the rate at which the heat consumed in generating steam is produced, allowing the steam generator 100 to continuously provide steam. In actual use, when the temperature of the main heater 11 and the auxiliary heater 12 reaches the set temperature, the system indicator light illuminates. At this time, the user presses the start button, and the electromagnetic pump supplies water to the heaters at a high flow rate, causing the main heater 11 and the auxiliary heater 12 to simultaneously generate a large amount of steam. This large amount of steam is sprayed directly onto the clothing through the steam outlet, generating a significant impact force, thus effectively smoothing out wrinkles and achieving the purpose of quick ironing.
[0087] It should be noted that the temperature detection system 3 can be a temperature sensor. The contact methods between the temperature sensor and the measured medium are divided into two main categories: contact and non-contact. Contact temperature sensors require thermal contact with the measured medium to ensure sufficient heat exchange and reach the same temperature. This type of sensor mainly includes resistive sensors, thermocouples, and PN junction temperature sensors. Non-contact temperature sensors do not need to contact the measured medium; instead, the temperature is measured through the thermal radiation or convection of the measured medium. This type of sensor mainly includes infrared temperature sensors. The main characteristic of this temperature measurement method is that it can measure the temperature of moving substances and objects with small heat capacity. In this invention, no specific type of temperature sensor is limited.
[0088] Furthermore, in order for the steam to achieve a good ironing effect, there are certain requirements for the required steam temperature. In this embodiment, the steam generating device 100 also includes an ironing head 4, which forms a steam channel and is connected to the steam chamber. The ironing head 4 is provided with a steam heater 41, which is used to heat the steam in the steam channel. By setting the ironing head 4 to perform secondary heating on the steam, the steam can reach the required temperature, thereby achieving a better ironing effect.
[0089] In an embodiment of the present invention, during operation, the main heater 11 and the steam heater 41 are pre-started. When the auxiliary heater 12 reaches the set power, it stops heating and enters an energy storage state. At this time, the steam heater 41 begins preheating to prepare for steam heating. When the user starts using the garment steamer, the water supply system 2 within the steam generator 100 sprays water onto the steam heater 41 and the auxiliary steam heater 12. The generated steam then enters the ironing head 4, which reheats the steam. To prevent the garment steamer from exceeding its rated power, the sum of the power of the main heater 11 and the auxiliary heater 12, as well as the sum of the power of the main heater 11 and the steam heater 41, does not exceed the rated power, and the steam heater 41 and the auxiliary steam heater 12 are not turned on simultaneously.
[0090] Specifically, because the water demand of the main heater 11 and the auxiliary heater 12 is inconsistent during use, when the steam needs to be generated at startup, the water supply system needs to spray water onto both the main heater 11 and the auxiliary heater 12 simultaneously. When the garment steamer only needs to deliver a steady amount of steam and does not require a large amount of steam, the water supply system only needs to spray water onto the main heater 11 and not onto the auxiliary heater 12. If the water supply system continues to spray water, the auxiliary heater 12 will not be heating during the steady steam phase, which will cause the water sprayed onto the auxiliary heater 12 to not vaporize in time. This will cause the steamer head to spray water, affecting its use. In order to facilitate the control of the water supply of the main heater 11 and the auxiliary heater 12, in this embodiment, the water supply system 2 includes a first water supply component 21 and a second water supply component 22. The first water supply component 21 is used to supply water to the main heater 11, and the second water supply component 22 is used to supply water to the auxiliary heater 12. By setting two sets of water supply components, it is convenient to control the water supply of each heater.
[0091] Specifically, to ensure precise control of the water supply to the main heater 11 and the auxiliary heater 12, in this embodiment, the first water supply component 21 includes a first water supply pipeline for spraying water onto the main heater 11; the second water supply component 22 includes a second water supply pipeline for spraying water onto the auxiliary heater 12; the water supply system 2 also includes valve bodies and common pipelines. Electromagnetically controlled industrial equipment is a basic automated component used to control fluids; it is an actuator, not limited to hydraulic or pneumatic. It is used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. Valve bodies work with different circuits to achieve the desired control, ensuring both accuracy and flexibility. Since there are many types of valve bodies, different valve bodies play different roles in the control system; the most commonly used are check valves, safety valves, directional control valves, and speed regulating valves. In this embodiment, the type of valve body is not limited. In this embodiment, only one valve body is provided. To facilitate the installation of the valve body, the first water supply pipeline and the second water supply pipeline are connected to the common pipeline. The common pipeline is equipped with the valve body, which is electrically connected to the control device. In this way, the water volume in the common pipeline can be adjusted by the adjustment function of the valve body, thereby adjusting the water spray volume of the first water supply pipeline and the second water supply pipeline. The water spray volume of the first water supply pipeline and the second water supply pipeline can be adjusted by the size of the pipe diameter to adjust their respective water supply volume.
[0092] Specifically, to facilitate better control of the two water supply components, in the first embodiment, the first water supply component 21 includes a first water supply pipeline for spraying water to the main heater 11. The first water supply pipeline is equipped with a first valve body, which is electrically connected to the control device. This allows for convenient adjustment of the water supply volume of the first water supply pipeline via the first valve body. In the second embodiment, the second water supply component 22 includes a second water supply pipeline for spraying water to the auxiliary heater 12. The second water supply pipeline is equipped with a second valve body, which is electrically connected to the control device. This allows for convenient adjustment of the water supply volume of the second water supply pipeline via the second valve body. The above two embodiments can only effectively control the water supply on a single water supply pipeline. If precise control of both pipelines is required, in the third embodiment, the first water supply component 21 includes a first water supply pipeline for spraying water onto the main heater 11. A first valve body is provided on the first water supply pipeline and is electrically connected to the control device. The second water supply component 22 includes a second water supply pipeline for spraying water onto the auxiliary heater 12. A second valve body is provided on the second water supply pipeline and is electrically connected to the control device. It can be understood that the two water supply pipelines are precisely regulated by different valve bodies, allowing the first and second water supply pipelines to precisely control the water spray volume according to the temperature of their respective heaters.
[0093] Taking a garment steamer as an example, the usage process and operating principle of a garment steamer are as follows:
[0094] When the garment steamer system is turned on, the main heater 11, the auxiliary heater 12, and the steam heater 41 are connected. During power design, the total power of these three heaters must not exceed the rated power. Alternatively, the sum of the power of the main heater 11 and the auxiliary heater 12, or the sum of the power of the main heater 11 and the steam heater 41, can be ensured not to exceed the rated power. This is achieved through program control, ensuring that the auxiliary heater 12 and the steam heater 41 do not operate simultaneously. First, the system preheats the main heater 11 and the auxiliary heater 12. During preheating, the program controls the main heater 11 and the auxiliary heater 12 to dry-burn, allowing a higher temperature setting, i.e., a first set value, such as 170℃. When the heater temperature reaches the set temperature of 170℃, the system indicator light illuminates, the auxiliary heater 12 stops heating, and the steam heater 41 of the steamer head begins heating, preheating the steam. At this time, when the user presses the start button, the valve body controls the water flow to supply a large volume of water to the main heater 11 and the auxiliary heater 12. The main heater 11 and the auxiliary heater 12 simultaneously generate a large amount of steam. This large amount of steam is ejected directly onto the clothing through the steam outlet of the ironing head 4, generating a significant impact force that effectively smooths out wrinkles and achieves rapid ironing. As water enters the main heater 11 and the auxiliary heater 12, their temperatures gradually decrease. As the temperature changes, the valve body adjusts the water supply according to the system program settings, ensuring that the garment steamer system does not spray water due to excessive spray volume and unvaporized water. When the user uses steam, the temperature of the main heater 11 and the auxiliary heater 12 gradually decreases during the water spraying process. However, because the main heater 11 continues to be powered on, it eventually reaches a stable temperature. When the temperature of the main heater 11 drops to another set value, namely the second set value, such as 130°C, the system will adjust to a stable operating state. At this time, the garment steamer system will enter a stable state of continuous steam spraying, i.e., producing continuous and stable steam. If the heater temperature has not yet dropped to the other set value, such as 130°C, and the user has stopped using the steam, meaning the user has not used the steamer head for ironing, the system will enter a heater preheating state. The steam heater 41 will stop heating, and the main heater 11 and the auxiliary heater 12 will preheat, thus generating a burst of steam, i.e., explosive steam, in the next cycle.
