Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to an ironing machine control circuit, an ironing machine control method, and an ironing machine. Background Technology

[0002] With the improvement of living standards, ironing machines, as a household appliance for ironing clothes, have become increasingly popular. Ironing machines typically have an ironing surface. Users hold the ironing machine so that the ironing surface contacts the clothes to be ironed. Ironing machines can include various models such as corded and cordless ironing machines.

[0003] In existing technology, irons typically have a built-in heating element. When in use, corded irons can continuously power the heating element through a constant connection to an external power source. Cordless irons, on the other hand, require connection to an external power source to preheat the heating element to a certain temperature. The heating element can store a certain amount of heat energy. When the cordless iron is used without an external power source, the heating element can maintain the ironing surface at the ironing temperature for a certain period using the stored heat energy, offering excellent operational convenience.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0049] Irons, as a household appliance for ironing clothes, have become increasingly popular. Irons typically have an ironing surface. Users hold the iron and place the ironing surface in contact with the clothes to be ironed. Currently, irons mainly include corded and cordless models. Irons usually have a heating element inside. When in use, corded irons can be continuously powered by an external power source to keep the heating element warm. Cordless irons, on the other hand, require connection to an external power source to heat up. Cordless irons can preheat the heating element to a certain temperature and store a certain amount of heat energy using an external power source. Once preheated, the user can disconnect the iron from the external power source and use it. During use, the heating element can maintain the ironing surface at the ironing temperature for a certain period of time using the stored heat energy, offering good operational convenience. However, current cordless irons suffer from problems such as short ironing temperature maintenance time and poor battery life after preheating.

[0050] To address the aforementioned technical problems, the ironing machine control circuit provided in this application provides two heating systems. This allows the ironing surface to maintain a good temperature during preheating, keeping the ironing temperature within a preset range for an extended period, thereby improving the ironing machine's battery life in wireless mode. The ironing machine of this application may include a first heating element and a second heating element. In the first heating system, the ironing machine can heat the first heating element using an external power source, thus heating the ironing surface. The first heating element can also store a certain amount of heat energy to maintain the ironing surface temperature after the wireless ironing machine is disconnected from the external power source. In the second heating system, the ironing machine can heat the second heating element using an internal battery after the wireless ironing machine is disconnected from the external power source, thereby delaying the duration of the ironing surface temperature.

[0051] Figure 1 A schematic diagram of the structure of an ironing machine according to an embodiment of this application is shown. Figure 1 The iron shown includes a main unit 100 and a power supply base 200. The main unit 100 and the power supply base 200 are detachably connected. For example, the main unit 100 and the power supply base 200 can be connected via a bayonet joint. The main unit 100 may also include a coupler 120. When the main unit 100 is connected to the power supply base 200, the main unit 100 can preheat by plugging into the power supply base 200 via the coupler 120. The power supply base 200 can be connected to an external power source via a cable, thereby providing power to the main unit 100. The iron's surface may also include a housing 140.

[0052] In one example, the main unit 100 can be used in conjunction with the power supply base 200 during ironing. In this case, the iron is in corded mode. During the use of this corded iron, an external power source can continuously supply power to the main unit via a cable to maintain the temperature of the heating plate 110 on the ironing surface.

[0053] In another example, the main unit 100 can be detached and used independently during ironing. In this case, the iron is in wireless mode. During use, the first heating element can maintain the temperature of the heating plate 110 using its stored heat energy. Simultaneously, the second heating element can be powered by an internal battery to extend the duration of the heating plate 110's temperature. When the temperature of the heating plate 110 of the wireless iron falls below a first preset temperature, an indicator light illuminates. This indicator light reminds the user to return the main unit 100 to the power socket 200 to continue heating the first heating element.

[0054] The technical solutions of this application will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0055] Figure 2 An embodiment of the present application provides a control circuit for an ironing machine. Figure 1 Based on the illustrated embodiment, the control circuit 300 can be housed inside the main unit 100 of the ironing machine, such as... Figure 2 As shown, the control circuit 300 in this embodiment may include a charging module 310, a first heating module 320, a second heating module 330, and a control module 340.

[0056] The charging module 310 is specifically... Figure 1 The circuit module in the power supply socket 200 shown. The charging module 310 may include a power supply terminal. The power supply terminal of the charging module 310 can be connected to an external power source via a cable. The charging module 310 may also include a live wire terminal (L), a neutral wire terminal (N), and a ground terminal (N). The ground terminal of the charging module 310 is grounded.

[0057] The first heating module 320 and the second heating module 330 can be located above the heating plate 110. The first end of the first heating module 320 is connected to the live wire of the charging module 310. The second end of the first heating module 320 is connected to the neutral wire of the charging module 310. The first heating module 320 can obtain electrical energy from an external power source through the charging module 310 and convert electrical energy into heat energy, thereby providing heat to the heating plate 110.

[0058] The first terminal of the control module 340 is connected to the live wire terminal of the charging module 310. The second terminal of the control module 340 is connected to the neutral wire terminal of the charging module 310. The third terminal of the control module 340 is connected to the first terminal of the second heating module 330. The fourth terminal of the control module 340 is connected to the second terminal of the second heating module 330. This control module 340 can control the second heating module 330 to heat up when the charging module 310 is not powered, thereby extending the duration of the heating plate 110's temperature. This control module 340 can also control the first heating module 320 to start or stop heating based on the temperature of the heating plate 110 when the charging module 310 is powered.

[0059] In one example, the first heating module 320 may specifically include a temperature control switch 321 and a first heating element 322. For example... Figure 3As shown, the first end of the first heating element 322 is the first end of the first heating module 320. The first end of the first heating element 322 is connected to the live wire end of the charging module 310. The second end of the first heating element 322 is connected to the first end of the temperature control switch 321. The second end of the temperature control switch 321 is the second end of the first heating module 320. The second end of the temperature control switch 321 is connected to the neutral wire end of the charging module 310. The temperature control switch 321 is used to turn the heating function of the first heating element 322 on or off. For example, when the temperature control switch 321 is on, the first heating element 322 can obtain electrical energy from an external power source through the charging module 310, and achieves a heating effect through the conversion of electrical energy into heat energy. When the temperature control switch 321 is off, the first heating element 322 can no longer obtain electrical energy from the power source and stops heating. During the use of this ironing machine, when the ironing machine is in corded mode, the first heating module 320 of the ironing machine remains continuously connected to the charging module 310. The control module 340 continuously monitors the temperature of the heating plate 110. When the temperature is below a first temperature threshold, the control module 340 controls the temperature control switch 321 to open, thereby heating the first heating element 322. When the temperature is above a third preset temperature, the control module 340 controls the temperature control switch to close. The first temperature threshold is lower than the third preset temperature. For example, the first temperature threshold can be 100 degrees Celsius, and the third preset temperature can be 180 degrees Celsius. When the temperature of the heating plate 110 is between the first temperature threshold and the third preset temperature, the iron can be in normal use, and the first heating element 322 stops heating. As usage continues, the temperature of the heating plate will gradually decrease from the third preset temperature to the first temperature threshold. The setting of the first temperature threshold is typically determined based on the boiling point of the liquid in the iron. For example, when the liquid used in the iron is water, the first temperature threshold is typically set to 100 degrees Celsius. This first temperature threshold setting allows the water in the iron to vaporize before it comes into contact with clothing. This iron can use steam to iron clothes. Optionally, the first heating element 322 can be an electric heating tube.

[0060] In one example, the control module 340 may specifically include a central control unit 341, an indicator light 342, a temperature sensing unit 343, and an atomizing unit 344. The connection status of each device can be as follows: Figure 3As shown. The first terminal of the central control unit 341 is the first terminal of the control module 340. The first terminal of the central control unit 341 is connected to the live wire terminal of the charging module 310. The second terminal of the central control unit 341 is the second terminal of the control module 340. The second terminal of the central control unit 341 is connected to the neutral wire terminal of the charging module 310. The central control unit 341 can determine the connection status between the main unit 100 of the ironing machine and the power supply socket 200 by connecting to the power supply module. The third terminal of the central control unit 341 is the third terminal of the control module 340. The third terminal of the central control unit 341 is connected to the first terminal of the second heating module 330. The fourth terminal of the central control unit 341 is the fourth terminal of the control module 340. The fourth terminal of the central control unit 341 is connected to the second terminal of the second heating module 330. The central control unit 341 can control the second heating module 330 by connecting to it. That is, the central control unit 341 can control the second heating module 330 to heat after the main unit is disconnected from the power supply module. The central control unit 341 can also control the second heating module 330 to stop heating when the main unit is connected to the power supply module. Furthermore, the fifth and sixth terminals of the central control unit 341 are connected to the first and second terminals of the indicator light 342, respectively. The indicator light 342 is used to indicate the status of the iron. For example, when the indicator light 342 is lit, it indicates that the iron is in use. Or, when the indicator light 342 flashes, it indicates that the cordless iron needs to be placed back on the base for charging and / or heating. Or, when the indicator light 342 is lit in a first color, it indicates that the iron is charging. The first color can be red. Or, when the indicator light 342 is lit in a second color, it indicates that the iron has finished heating and / or charging and can be used. The second color can be green. The central control unit 341 can determine the lighting mode of the indicator light 342 by acquiring information such as power and temperature, thereby indicating the status of the ironing machine. The seventh and eighth terminals of the central control unit 341 are connected to the first and second terminals of the atomizing unit 344, respectively. The atomizing unit 344 is used to atomize the liquid in the ironing machine. Specifically, the atomizing unit 344 can improve the atomization efficiency of the liquid in the ironing machine, thereby ensuring that the ironing machine can spray out the atomized liquid during ironing. Optionally, the atomizing unit 344 can be an ultrasonic atomizing sheet. The ninth and tenth terminals of the central control unit 341 are connected to the first and second terminals of the temperature sensing unit 343, respectively. The temperature sensing unit 343 can be disposed on the surface of the heating plate 110 to acquire the surface temperature of the heating plate 110 in real time. It should be noted that the temperature sensing unit 343 can be a temperature sensor, a thermistor, or other similar device. The temperature sensing unit 343 can be connected by inserting it into the printed circuit board of the central control unit 341. Therefore, in Figure 3 In this configuration, the ninth and tenth terminals of the central control unit 341 are combined into a single port. That is, in... Figure 3In the diagram, the circuit formed by the central control unit 341 and the temperature sensing unit 343 is represented by a connecting line.

[0061] In one example, the central control unit 341 specifically includes a controller 3411 and a battery 3412. The controller 3411 can specifically be a printed circuit board. The battery 3412 can be fixed to the printed circuit board. The controller 3411 and the battery 3412 can be configured as follows: Figure 4 As shown. The central control unit 341 can be connected to the wall of the receiving slot 131 of the central control housing 130 via fasteners. The battery 3412 can be a lithium battery. When the main unit 100 is connected to the power supply socket 200, the battery 3412 can obtain power from an external battery to charge itself. The battery 3412 can be used to power the controller 3411, indicator light 342, temperature sensing unit 343, ultrasonic atomizer 344, and second heating module 330.

[0062] In one example, the second heating module 330 may specifically be a second heating element 331. Optionally, the second heating element 331 may be a ceramic heating plate.

[0063] In one example, the control circuit 300 may further include a fuse 350. A first end of the fuse is connected to the live wire of the charging module 310. A second end of the fuse is connected to a first end of the first heating module 320. The fuse is used to protect the control circuit 300.

[0064] In one example, the arrangement of the various components in the control circuit on the ironing surface can be as follows: Figure 5As shown. The heating plate 110 is disposed on the bottom surface of the ironing surface. The heating plate 110 can directly contact the clothing to achieve high-temperature ironing. A temperature control switch 321 is disposed at the front end of the ironing surface. The switch assembly of the temperature control switch 321 can be disposed on the surface of the iron's housing 140 so that the user can touch the temperature control switch 321 to control the iron. The first heating element 322 in the first heating module 320 can be disposed on both sides of the rear end of the ironing surface. The lower end of the first heating element 322 can be connected to the heating plate 110. When the first heating element 322 is heated, it can conduct heat to the heating plate 110, thus heating the heating plate 110. A second heating element 331 can be disposed between the two first heating elements 322. The bottom surface of the second heating element 331 contacts the heating plate 110 for heating the heating plate 110. A mounting plate 151 can be disposed above the second heating element 331. The mounting plate 151 is used to fix the second heating element 331. A temperature sensing unit 343 can be disposed above the mounting plate 151. A fixing member 152 can be disposed above the temperature sensing unit 343. The fixing member 152 is used to fix the temperature sensing unit 343. The ironing surface may also include an air outlet 160 in the middle. Liquid in the ironing machine can be atomized by the atomizing unit 344 and discharged through the air outlet 160.

[0065] The ironing machine control circuit provided in this application includes a charging module, a first heating module, a second heating module, and a control module. The first heating module can be connected to the charging module to provide power to the ironing machine's main unit when it is connected to the power supply socket via the charging module of the power supply socket. The control module can also be connected to the charging module to charge the battery in the control module when the ironing machine's main unit is connected to the power supply socket via the charging module of the power supply socket. The control module can also be connected to the second heating module to heat the heating plate of the ironing surface when the ironing machine's main unit is disconnected from the power supply socket. The control module may also include a temperature sensing unit to acquire the temperature of the heating plate in real time and control the ironing machine based on the temperature. The control module may also include an ultrasonic atomizer to atomize the liquid in the ironing machine to facilitate ironing clothing. In this application, by using the second heating module, the temperature maintenance time of the heating plate of the ironing surface is extended when the ironing machine is in wireless mode.

[0066] Figure 6 A flowchart illustrating an embodiment of an ironing machine control method provided in this application is shown. Figures 2 to 5 Based on the illustrated embodiments, as Figure 6 As shown, with the controller in the ironing machine as the executing entity, the method in this embodiment may include the following steps:

[0067] S101. The temperature of the heating plate of the iron is obtained through the temperature sensing unit.

[0068] In this embodiment, the controller can obtain the heating plate temperature in real time through a temperature sensing unit after the iron is powered on. This temperature sensing unit can be powered by a battery to enable its operation.

[0069] S102. When the temperature of the heating plate is lower than the first preset temperature, turn on the temperature control switch and heat the heating plate through the first heating element.

[0070] In this embodiment, the controller can determine the temperature of the heating plate. When the temperature of the heating plate is lower than a first preset temperature, the iron needs to heat the heating plate through the first heating element. When the iron is in wired mode, the controller can directly control the temperature control switch to turn on, thereby heating the first heating element. When the iron is in wireless mode, the controller can control the indicator light to flash to remind the user to return the iron to the power socket. When the controller detects the charging module, it can determine that the main unit has been returned to the power socket. At the same time, the controller can control the indicator light to illuminate a first color. The first color can be red, used to indicate that the main unit is in charging and / or heating state. When the main unit is returned to the charging socket, the controller can control the temperature control switch to turn on, thereby heating the first heating element.

[0071] Optionally, the first preset temperature can be 100 degrees Celsius, or a value slightly higher than 100 degrees Celsius. Since the liquid in this iron is typically water, which has a boiling point of 100 degrees Celsius, the first preset temperature can be set to 100 degrees Celsius based on its boiling point. This first preset temperature setting ensures that the atomized liquid remains atomized after being heated by the heating plate, thereby improving ironing efficiency and effect. If the first preset temperature is below 100 degrees Celsius, the atomized liquid may re-liquefy after passing through the heating plate, reducing the ironing effect.

[0072] S103. When the heating plate temperature is greater than or equal to the third preset temperature, the temperature control switch is turned off, and the gas is atomized through the heating plate and the atomizing unit.

[0073] In this embodiment, the controller can determine the temperature of the heating plate. When the heating plate temperature is greater than or equal to a third preset temperature, the controller can automatically turn off the temperature control switch to stop the first heating element from heating, thereby preventing the heating plate temperature from becoming too high due to continuous heating. Simultaneously, the controller can also control the indicator light to illuminate a second color. This second color can be green. When the indicator light illuminates the second color, it indicates that the iron has completed charging and / or heating. At this time, the user can continue using the iron in wired mode. Alternatively, the user can remove the main unit of the iron and use it wirelessly.

[0074] Optionally, the third preset temperature can be a temperature higher than the first preset temperature. For example, the third preset temperature can be 180 degrees Celsius. Too high a temperature may damage the clothes, while too low a temperature will cause the iron to need to heat up frequently.

[0075] When the iron is in use, the controller can also atomize the liquid in the iron through the atomization unit. The atomized liquid will then pass through... Figure 5 The air is discharged through the outlet shown. The atomized liquid sprayed from the outlet can be heated by the heating plate. When the atomized liquid reaches the clothing, it is typically at a high temperature. This ironing machine can iron clothing using this high-temperature atomized liquid.

[0076] In one example, when the iron is in wireless mode, the controller can also determine whether the heating plate temperature is lower than a second preset temperature. Optionally, the second preset temperature is a temperature between a first preset temperature and a third preset temperature. For example, the second preset temperature could be 130 degrees Celsius. When the heating plate temperature is lower than the second preset temperature, the controller can control a second heating element to operate, thereby heating the heating plate and extending its usage time. That is, when the controller determines that the heating plate temperature is lower than the second preset temperature, the controller can use a battery to power the second heating element to heat it.

[0077] In one example, the controller can also monitor the battery level. If the battery level is lower than a preset level, the controller can shut down the second heating element by turning it off, thus disabling its heating function. That is, when the battery level is lower than the preset level, even if the heating plate temperature is lower than a second preset temperature, the controller will not activate the second heating element. This setting ensures the operation of the atomizing unit and the temperature sensing unit. When the battery level is lower than the preset level, the remaining battery power will be used for the atomizing unit to atomize the liquid, to obtain the heating plate temperature, and for the basic operation of the controller. Optionally, the preset level can be a percentage of the battery level, such as 15%.

[0078] The ironing machine control method provided in this application allows the controller to acquire the heating plate temperature in real time via a temperature sensing unit after the ironing machine is powered on. The controller can determine the heating plate temperature. When the heating plate temperature is lower than a first preset temperature, the ironing machine needs to heat the heating plate using a first heating element. When the heating plate temperature is greater than or equal to a third preset temperature, the controller can automatically turn off the temperature control switch to stop the first heating element from heating. The controller can also atomize the liquid in the ironing machine using an atomizing unit. When the ironing machine is in wireless mode, the controller can also determine whether the heating plate temperature is lower than a second preset temperature. When the heating plate temperature is lower than the second preset temperature, the controller can heat the heating plate using a second heating element to extend the heating plate's usage time. In this application, by adding a second heating element, the ironing machine can maintain a temperature above the first preset temperature for a longer period, thereby increasing the usage time of the ironing machine in wireless mode, improving efficiency and user experience.

[0079] Based on the above embodiments, Figure 7 The diagram shows a usage process for an ironing machine. This usage process may include the following steps:

[0080] S201. Users can place the main unit on the power supply cradle. When the main unit is placed on the power supply cradle, the controller can detect that the main unit is connected to the power supply cradle.

[0081] S202, The controller can control the first heating element to start heating. After the first heating element is heated, the heating plate of the ironing surface of the main unit is heated by the first heating element.

[0082] S203. The controller can obtain the heating plate temperature through the temperature sensing unit. When the heating plate temperature is lower than the third preset temperature, the controller can return to step S202 and continue to heat the heating plate through the first heating element. Optionally, the third preset temperature can be a value greater than or equal to the first preset temperature. For example, the third preset temperature can be 100 degrees Celsius. Or, for example, the third preset temperature can be 180 degrees Celsius.

[0083] S204. When the heating plate temperature is greater than or equal to the third preset temperature, the controller can control the liquid atomization in the ironing machine through the atomization unit.

[0084] S205. When the temperature of the heating plate is greater than or equal to the third preset temperature, the first heating element stops heating.

[0085] S206. When the heating plate temperature is greater than or equal to the third preset temperature, the controller can determine the working status of the iron by its connection status with the power supply socket. This working status can include both wireless and wired modes. When the iron is in wired mode, the main unit of the iron is connected to the power supply socket, and the power supply socket is connected to an external power source via a cable. When the iron is in wireless mode, the main unit of the iron is detached from the power supply socket and used independently.

[0086] It should be noted that the execution order of the above steps S204, S205, and S206 is not limited by the order of the described actions. Steps S204, S205, and S206 can be performed in other orders or simultaneously.

[0087] S207. When the host is in wireless mode, the battery cannot continue to draw power from an external power source because the host is disconnected from the power supply. Therefore, the battery stops charging.

[0088] S208. The server can continue to acquire the heating plate temperature in real time. The server can compare this heating plate temperature with a second preset temperature. The second preset temperature can be a temperature slightly higher than the first preset temperature. For example, the second preset temperature can be 130 degrees Celsius. When the heating plate temperature is greater than or equal to the second preset temperature, the controller does not perform any action.

[0089] S209. When the heating plate temperature is lower than the second preset temperature, the server can obtain the remaining battery power in real time. The server can compare the remaining battery power with the preset power level. The preset power level can be a percentage of the battery power, such as 15%. Since the controller only needs to control the second heating element to heat up when the heating plate temperature is lower than the second preset temperature, and the controller needs to control the atomizing unit and the temperature sensing unit to operate regardless of whether the heating plate temperature is lower than the second preset temperature, the controller only needs to determine whether the remaining battery power is sufficient when the heating plate temperature is lower than the second preset temperature.

[0090] S210. When the remaining battery power is greater than or equal to the preset battery power, the server can control the second heating element to start heating. Heating by the second heating element will allow the heating plate to maintain a temperature greater than or equal to the first preset temperature for a longer period of time, thereby extending the working time of the iron in wireless mode.

[0091] S211. When the remaining battery power is less than the preset battery power, the remaining battery power is insufficient. At this time, the battery power is preferentially supplied to the temperature sensing unit and the atomizing unit to maintain the normal operation of the iron. Therefore, when the remaining battery power is less than the preset battery power, the controller shuts off the heating function of the second heating element. After the heating function of the second heating element is shut off, the second heating element will not be able to start, regardless of whether the temperature of the heating plate is lower than the second preset temperature.

[0092] S212. Regardless of whether it's in wireless or wired mode, the controller needs to compare the heating plate temperature with a first preset temperature after acquiring the temperature. If the heating plate temperature is lower than the first preset temperature, the iron needs to activate the first heating element via the power supply socket to heat the heating plate. The first preset temperature can be determined based on the boiling point of the liquid in the iron. For example, when the liquid is water, the first preset temperature can be 100 degrees Celsius.

[0093] S213. When the temperature of the heating plate is greater than or equal to the first preset temperature, the iron can be used to iron clothes.

[0094] The ironing machine control method provided in this application allows the controller to control a first heating element to heat the heating plate after the main unit is placed on the power socket. When the heating plate temperature is greater than or equal to a third preset temperature, the controller can control the liquid in the iron to atomize through the atomization unit and stop the first heating element from heating. When the ironing machine is in wireless mode, the controller can stop battery charging. The controller can control a second heating element to heat the heating plate when the heating plate temperature is lower than a second preset temperature and the remaining battery power is greater than or equal to a preset battery power. The controller can also turn off the heating function of the second heating element when the remaining battery power is less than a preset battery power. The controller can also remind the user to put the main unit back on the power socket when the heating plate temperature is lower than the first preset temperature. In this application, by adding a second heating element, the ironing machine can maintain a temperature above the first preset temperature for a longer period of time, thereby increasing the usage time of the ironing machine in wireless mode, improving usage efficiency and user experience.

When the ironing machine control circuit is powered on, the ironing machine can also be used to achieve the following: Figure 6 or Figure 7 The ironing machine control method shown.
