Description

Technical Field

[0001] This invention relates to the field of ironing device technology, specifically to a method for detecting the absence of water in an iron with a water pump and an iron with a water pump. Background Technology

[0002] The working principle of a traditional water pump iron typically includes three main parts. The first part is heating control, where the heating plate is controlled by a thermostat (including mechanical and electronic thermostats). Heating is activated when the temperature is below the control point and deactivated when the temperature is above the control point. The second part is steam control, which is controlled by a water pump. When the user uses the iron, the water pump is responsible for drawing water into the heating element for vaporization. The third part is detecting whether the heating plate is heating (this is not necessary for electronically controlled irons, as heating is controlled by an electronic board). During the first heating cycle, this signal is used to confirm that the temperature has been reached, and an indicator light indicates to the user that steam can be used.

[0003] Therefore, the heat preservation after the required temperature is reached has the following characteristics: In the case of continuous steamlessness, the heating time is T1 (very short), and the no-heating time is T2 (longer, mainly due to natural cooling); in the case of continuous steam, the heating time is T3 (the heating time becomes very long), and the no-heating time is T4 (becomes very short when not heated due to water vaporization). Therefore, the traditional method for determining no water is generally as follows: in the case of continuous steam, if the heating time becomes closer to T1 or the no-heating time becomes closer to T2, then it is considered to be without water.

[0004] However, users may not use an iron for an extended period at a time, but rather use the steam intermittently. In this case, the aforementioned conventional method for determining if there is no water becomes ineffective. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing detection methods when users do not use steam continuously. By monitoring the time when the user starts using steam and the cumulative time the user uses steam within that period, the invention determines whether a heating signal has not been detected when the cumulative steam usage time reaches a preset value. This allows for a convenient way to determine whether the water pump is short of water without increasing costs. This method can be matched to users' intermittent steam usage habits, making the water shortage detection more accurate.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Methods for detecting dry irons with water pumps include:

[0008] S1. The heating plate is preheated, but the iron should not emit steam.

[0009] S2. Determine if the heating plate has reached the set temperature. If yes, proceed to S3; otherwise, proceed to S1.

[0010] S3. The heating plate has been heated to the set temperature. The steam function can be turned on. Then proceed to step S4.

[0011] S4. Identify whether the user has turned on the steam function. If yes, proceed to S5; otherwise, proceed to S3.

[0012] S5. Check if the heating plate is heating. If yes, clear timer T1 and timer T2 and then execute S3. If no, execute S6.

[0013] S6, T1 timer, determine if T1 has reached the first time, if yes, execute S10, if no, execute S7;

[0014] S7. Determine if the steam function is on. If yes, proceed to S8; otherwise, proceed to S9.

[0015] S8 and T2 accumulate the timer, then S5 is executed;

[0016] S9 and T2 stop the timer, then execute S5;

[0017] S10. Determine if T2 has reached the second time. If yes, determine if there is no water. If no, clear timers T1 and T2 and then execute S3.

[0018] Furthermore, the system determines whether the set temperature has been reached in S2 and / or whether the iron is heating up in S5 by identifying the thermostat status.

[0019] Furthermore, S2 includes:

[0020] S21. Heating plate preheating, steam function is turned off during this stage;

[0021] S22. The processor detects the temperature controller's action signal and determines whether the temperature controller has overheated. If yes, execute S3; otherwise, execute S21.

[0022] Furthermore, in S3, the temperature controller status signal is obtained through the CHK line to determine whether to allow the steam function to be turned on.

[0023] Furthermore, in S4, the user's button signal is used to identify whether the user has activated the steam function.

[0024] Furthermore, the first time is 30-60 seconds, and the second time is 10-30 seconds.

[0025] Furthermore, it also includes: S11, turning off heating and steam functions, waiting for the user to add water; after adding water, return to S1.

[0026] Another object of the present invention is to provide an iron with a water pump, comprising a processor, a memory, a heating element and a steam element, wherein the memory stores a computer program, which is loaded and executed by the processor to implement the method described above.

[0027] By adopting the above technical solution, the present invention has the following advantages compared with the prior art:

[0028] This invention monitors the time when a user starts using steam and the cumulative time the user uses steam within that time period. It determines whether a heating signal is detected after the user's cumulative steam usage time reaches a threshold, thereby determining whether the water pump is actually discharging water and whether there is a water shortage. The detection method is convenient and can adapt to the user's intermittent steam usage scenario. Attached Figure Description

[0031] 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:

[0032] Example

[0033] One of the objectives of this invention is to provide a method for detecting the absence of water in an iron with a water pump. The core solution is as follows: when a user starts using steam, a timer T1 is started. This timer continues to accumulate regardless of whether the user uses the steam again until it reaches the zeroing condition. When time T1 expires, time T2 is cleared simultaneously.

[0034] Within time T1, the user's steam usage time T2 is recorded. If no heating signal is detected after time T2, it is determined that there is no water.

[0035] To facilitate understanding of the present invention, a detailed description will be provided in conjunction with the accompanying drawings.

[0036] Please refer to Figure 1 As shown, the present invention provides a method for detecting the absence of water in an iron with a water pump, comprising:

[0037] S1. The heating plate is preheated, but the iron should not emit steam.

[0038] S2. Determine if the heating plate has reached the set temperature. If yes, proceed to S3; otherwise, proceed to S1.

[0039] S3. The heating plate has been heated to the set temperature. The steam function can be turned on. Then proceed to step S4.

[0040] S4. Identify whether the user has turned on the steam function. If yes, proceed to S5; otherwise, proceed to S3.

[0041] S5. Check if the heating plate is heating. If yes, clear timer T1 and timer T2 and then execute S3. If no, execute S6.

[0042] S6, T1 timer, determine if T1 has reached the first time, if yes, execute S10, if no, execute S7;

[0043] S7. Determine if the steam function is on. If yes, proceed to S8; otherwise, proceed to S9.

[0044] S8 and T2 accumulate the timer, then S5 is executed;

[0045] S9 and T2 stop the timer, then execute S5;

[0046] S10. Determine if T2 has reached the second time. If yes, determine that there is no water and execute S11. If no, clear the timers T1 and T2 and then execute S3.

[0047] S11: Turn off heating and steam functions, and wait for the user to add water; return to S1 after water is added.

[0048] In this embodiment, S1 determines whether the set temperature has been reached by identifying the state of the thermostat. Therefore, S1 includes:

[0049] S11. Heating plate preheating, steam function is turned off during this stage;

[0050] S12. The processor detects the temperature controller's action signal and determines whether the temperature controller has overheated. If yes, execute S2; otherwise, execute S11.

[0051] In S1, heating plate preheating refers to the process of heating the plate from a low temperature until the set temperature is reached, allowing the steam function to be activated. During the preheating phase, the steam function cannot be activated. Please refer to [link / reference needed]. Figure 2 As shown, in this embodiment, S2 identifies the thermostat status through the CKH line, and then shuts down or allows the steam function to be turned on. That is, the processor (set in the PCBA) detects the thermostat's action signal through the CHK line. Before detecting an over-temperature action, it is determined that the preset temperature has not been reached, and the PCBA does not allow the water pump to be turned on. When the thermostat has over-temperature action at least once (over-temperature disconnection when the set temperature is reached), it is determined that the set temperature has been reached. At this time, the water pump control circuit is connected, and the steam function is allowed to be turned on. At this time, the steam preparation state of S3 is entered, waiting for the user to turn on the steam.

[0052] In S4, the processor identifies whether the user has turned on the steam function through the user's key press signal. Thus, in S5, when the user turns on the steam and no heating is detected, T1 starts timing. T1 will continue timing continuously regardless of whether the user continues to use the steam until the zero condition is reached (the heating plate starts heating); at the same time, timing T2 is only used to calculate the time the user uses the steam (in other words, the cumulative time the water pump has been running).

[0053] Specifically, if the heating plate is heating, it means the water pump is actually discharging water, and the heating plate needs to heat up to maintain its temperature. Therefore, if heating is detected, T1 and T2 are cleared, and the process returns to S2 to start a new round of testing. If not, it is suspected that there is no water, and the process enters T2 to further confirm whether there is no water.

[0054] The time T1 and the time T2 can be flexibly set according to the specific product. In a specific embodiment of the present invention, T1 is 30-60s and T2 is 10-30s.

[0055] In S11, after adding water, return to S1. The water adding action can be identified by the water adding button signal.

[0056] Another object of the present invention is to provide an iron with a water pump, comprising a processor, a memory, a heating element, and a steam element. Please refer to... Figure 2 As shown, 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 realizing the steam function. The processor and memory described in this application are mounted in the PCBA. The memory stores a computer program, which is loaded and executed by the processor to implement the method described above.

[0057] 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 and conveniently realizes waterless detection without increasing costs.
