Description

Technical Field

[0001] This invention relates to the field of ironing device technology, specifically to a control method for automatically adjusting the amount of steam on an iron and an iron in general. Background Technology

[0002] Before steam is produced, the aluminum plate of the iron's soleplate stores a significant amount of heat while maintaining a certain high temperature. When water is added, this heat vaporizes a large amount of water, resulting in steam volume A. As the temperature drops and the iron begins to heat up, the amount of steam vaporized under continuous heating, according to the energy conversion formula, is B, but the value of B is much smaller than A. Therefore, a control logic is needed to adjust the water pump's output.

[0003] Current control logic:

[0004] Using a fixed steam output A initially produces a large amount of steam, but if the user irons for even a short period, the iron will start dripping. Using a fixed steam output B produces a smaller amount of steam, resulting in low ironing efficiency and a poor user experience. Therefore, different steam outputs can be set for different time periods, supplying steam at output A after the first period and at output B after the first period. However, this still has drawbacks: when the user stops using steam, the iron is not continuously heating, and the existing iron control logic does not fully account for heat conversion, still leading to dripping.

[0005] Another method is to add an NTC (Non-Temperature Control) sensor to detect the bottom plate temperature and adjust the steam output. Because the NTC device is located above the bottom plate inside the iron, the temperature at the NTC placement point lags behind the bottom plate temperature. Consequently, the steam output always lags behind the actual temperature, ultimately causing the iron to drip.

[0006] Therefore, this application aims to find a control method for automatically adjusting the amount of steam on an iron without increasing costs, in order to solve the problem of dripping water. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing control methods, which are not based on the fact that the iron is not constantly heating. By setting a timer T2 when the steam function of the iron is turned off to count the cumulative heating time of the iron, the amount of steam can be adjusted accordingly to prevent the iron from dripping water.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] The control method for automatically adjusting the steam output on an iron includes:

[0010] Step 1: The iron is in preheating mode, but no steam is coming out. Then proceed to Step 2.

[0011] Step 2: The processor detects the temperature controller trip signal to determine if it has tripped once; if the result is no, proceed to Step 1; if the result is yes, proceed to Step 3.

[0012] Step 3: The iron is now heated to the set temperature. You can use the steam function. Then proceed to Step 4.

[0013] Step 4: Determine if the user has turned on the steam function. If the result is no, proceed to step 7; if the result is yes, proceed to step 5.

[0014] Step 5: The processor starts a timer T1 and clears timer T2, then proceeds to step 6;

[0015] Step 6: When T1 is less than or equal to the first time, execute the first steam quantity; when T1 is greater than the first time, execute the second steam quantity, and then execute Step 4 when the iron's steam function is turned off.

[0016] Step 7: Determine if heating is in progress. If yes, proceed to step 8; otherwise, proceed to step 4.

[0017] Step 8: Start a timer T2, and determine if timer T2 is greater than or equal to the second time. If the result is positive, proceed to step 9; otherwise, proceed to step 4.

[0018] Step 9: Stop timing T2 and clear timing T1, then proceed to step 4.

[0019] Furthermore, the first steam flow rate is 80-120 g / min, and the second steam flow rate is 20-40 g / min.

[0020] Furthermore, the first time is set to 4-6 seconds; the second time is set to 6-10 seconds.

[0021] Furthermore, the first steam flow rate is 100 g / min, and the second steam flow rate is 30 g / min.

[0022] Furthermore, the first time is 5 seconds, and the second time is set to 8 seconds.

[0023] Another object of the present invention is to provide an iron including a heating assembly, a steam assembly, and a PCBA, wherein the PCBA is provided with a memory and a processor, the memory storing a computer program, the computer program being loaded and executed by the processor to implement the method described above.

[0024] By adopting the above technical solution, the present invention has the following advantages compared with the prior art:

[0025] This invention starts counting the heating time when the steam function is turned off. When the time reaches a certain value, the steam control logic can only restart from the first steam quantity when the user restarts the steam switch. In other cases, it operates according to the second steam quantity. This control method fully considers the heat conversion capacity of the heating plate. Steam is only supplied from the first steam quantity when the heating plate has accumulated a certain amount of heat (after heating for a certain time), thus avoiding dripping. In other cases, steam is supplied according to the second steam quantity, thereby achieving a balance between dripping and ironing efficiency. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. Furthermore, it should be noted that:

[0029] Example

[0030] One of the objectives of this invention is to provide a control method for automatically adjusting the amount of steam on an iron. The core solution is as follows: when the steam function is turned off, the heating time is counted. When the time reaches a certain value, the user restarts the steam switch, and the steam control logic can then start executing from the first steam quantity again. In other cases, it is executed according to the second steam quantity, so as to achieve a balance between dripping water and ironing efficiency.

[0031] To facilitate understanding of the present invention, a detailed description will be provided in conjunction with the accompanying drawings.

[0032] Please refer to Figure 1 As shown, the control method for automatically adjusting the steam volume on the iron of the present invention includes:

[0033] Step 1: The iron is in preheating mode, and no steam is coming out. Then proceed to Step 2. Preheating mode refers to the process of the iron starting to heat up from a low temperature until it reaches the set temperature setting.

[0034] Step 2: The processor detects the thermostat trip signal to determine if it has tripped once. If the result is no, proceed to Step 1; if the result is yes, proceed to Step 3. That is, by checking if the thermostat has tripped, it determines whether the set temperature has been reached. If yes, proceed to the next step; otherwise, return to Step 1 to continue preheating.

[0035] Step 3: The iron has been heated to the set temperature and the steam function can be used. Then proceed to Step 4. At this point, when the iron has heated to the set temperature, the PCBA will obtain the corresponding information from the thermostat via the CHK line. Subsequently, the PCBA will activate the water pump's water supply control circuit. At this time, the steam function is enabled. That is, if the steam function button is pressed at this time, the water pump's water supply control circuit will be fully activated, and the water pump can pump water.

[0036] Step 4: Determine if the user has turned on the steam function. If the result is no, proceed to step 7; if the result is yes, proceed to step 5.

[0037] Step 5: The processor starts a timer T1 and clears timer T2, then proceeds to step 6.

[0038] Step 6: When T1 is less than or equal to the first time, execute the first steam quantity; when T1 is greater than the first time, execute the second steam quantity, and then execute Step 4 when the iron's steam function is turned off.

[0039] That is, if the user turns on the steam function, the processor starts a timer T1. While T1 is less than or equal to the first time, steam is supplied at the larger first steam quantity. After the first time, steam is supplied at the second steam quantity. However, if the steam function status of the iron changes during this process, i.e., the user turns off the steam function, then the process returns to step four for a new judgment.

[0040] Step 7: Determine if heating is in progress. If yes, proceed to step 8; otherwise, proceed to step 4.

[0041] Step 8: Start a timer T2, and determine if timer T2 is greater than or equal to the second time. If the result is positive, proceed to step 9; otherwise, proceed to step 4.

[0042] Step 9: Stop timing T2 and clear timing T1, then proceed to step 4.

[0043] That is, the heating time of the iron is calculated by timing T2. When the heating time of the iron is greater than or equal to the second time, it is considered that the heating plate of the iron has stored enough heat. At this time, the timing T1 is cleared, and then the process returns to step four. When the user turns on the steam function, steam is supplied directly from the first steam quantity. However, if the timing T2 is less than the second time, it is considered that the heating plate of the iron does not have enough heat. At this time, the process immediately jumps back to step four. When the user turns on the steam function again, T1 is not cleared. In this way, when the time T1 is greater than the first time, steam is supplied according to the second steam quantity, instead of starting directly from the first steam quantity, thus avoiding dripping due to excessive steam.

[0044] In one specific embodiment of the present invention, the first steam flow rate is 80-120 g / min; the second steam flow rate is 20-40 g / min. In this case, the first time is set to 4-6 seconds, and the second time is set to 6-10 seconds.

[0045] In a more specific embodiment of the present invention, the first steam flow rate is 100 g / min; the second steam flow rate is 30 g / min. In this case, the first time is set to 5 seconds, and the second time is set to 8 seconds.

[0046] Another object of the present invention is to provide an iron including a heating assembly, a steam assembly, and a PCBA, wherein the PCBA is provided with a memory and a processor, the memory storing a computer program, the computer program being loaded and executed by the processor to implement the method described above.

[0047] Please refer to Figure 2 As shown, specifically, the heating component includes a thermostat TC and a heating plate R. The thermostat TC controls the heating of the heating plate R and sets its intensity level. The steam component includes a water pump M and a CHK line. The status information of the thermostat TC is obtained through the CHK line, thereby determining whether to release and allow the water pump M to start, thus enabling the steam function. The processor and memory described in this application are integrated into the PCBA.

[0048] In this application, PCBA, CHK, thermostat and heating plate are all electronic components already present in existing irons. This application does not add any other components. Without increasing costs, the amount of steam on the iron can be flexibly controlled to avoid dripping.
