Description

Technical Field

[0001] This invention relates to the field of garment care equipment technology, and specifically provides a garment care equipment and a control method and control device for a steam generating component. Background Technology

[0002] Washing machines, washer-dryer combos, garment care machines, steam irons, and other garment care equipment are usually equipped with steam generators.

[0003] The steam box of a steam generator stores water for steam generation, and a level detection device is installed inside the steam box. There are two types of level detection devices: probe-type and float-type. Probe-type level detection devices determine the water level by detecting the conductivity of the water with a probe. However, different types or temperatures of water have different conductivity. Even with the same water level, the detection results of probe-type level detection devices will differ, affecting their accuracy and negatively impacting the garment care equipment. In particular, during the water replenishment period, the water replenishment system may erroneously stop replenishing water, resulting in insufficient water in the steam box, reduced steam generation efficiency, and decreased steam output, thus affecting the garment care effect. Float-type level detection devices determine the water level by detecting the position change of a float. However, during steam generation, the water is boiling, causing the float to move significantly with the water surface, thus affecting the accuracy of the level detection. Summary of the Invention

[0004] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem of low accuracy and reliability of liquid level detection in existing steam generation components.

[0005] In a first aspect, the present invention provides a control method for a steam generating assembly, the steam generating assembly including a steam box, the steam box being provided with a float-type liquid level device and a probe-type liquid level device, the control method comprising:

[0006] Water begins to enter when the steam box is emptied.

[0007] During water intake, when the float-type liquid level device detects that the water in the steam box has reached a preset low liquid level, the first liquid level value detected by the probe-type liquid level device is obtained.

[0008] The probe-type liquid level device determines a first standard liquid level value based on the first liquid level value, and the first liquid level value and the first standard liquid level value have a preset mapping relationship.

[0009] During steam generation, it is determined whether water replenishment is needed based on the first standard liquid level value and the real-time detection value of the probe-type liquid level device.

[0010] In some feasible embodiments of the control method for the steam generating component described above, the mapping relationship between the first liquid level value and the first standard liquid level value is as follows:

[0011] B1 = K1 * L1,

[0012] Where B1 is the first standard liquid level value, L1 is the first liquid level value, and K1 is a constant.

[0013] In some feasible implementations of the control method for the steam generating assembly described above, the step of "determining whether water replenishment is needed based on the first standard liquid level value and the real-time detection value of the probe-type liquid level device" includes:

[0014] If the real-time detection value is less than or equal to the first standard liquid level value, it is determined that water needs to be added; or

[0015] If the real-time detection value is greater than or equal to or greater than the first standard liquid level value, it is determined that no water replenishment is required.

[0016] In some feasible embodiments of the above-described control method for the steam generating assembly, the control method further includes:

[0017] During water intake, when the float-type liquid level device detects that the water in the steam box has reached a preset high liquid level, the second liquid level value detected by the probe-type liquid level device is obtained.

[0018] The standard liquid level change rate is determined based on the first liquid level value and the second liquid level value;

[0019] During water replenishment, when the float-type liquid level device detects that the water in the steam box has reached the preset low liquid level, it obtains the third liquid level value detected by the probe-type liquid level device. When the float-type liquid level device detects that the water in the steam box has reached the preset high liquid level, it obtains the real-time liquid level value of the probe-type liquid level device.

[0020] Based on the third liquid level value and the real-time liquid level value, the actual liquid level change rate is determined;

[0021] Based on the standard liquid level change rate and the actual liquid level change rate, determine whether to stop water replenishment.

[0022] In some feasible embodiments of the control method for the steam generating assembly described above, the step of "determining the standard liquid level change rate based on the first liquid level value and the second liquid level value" includes:

[0023] Based on the first liquid level value and the second liquid level value, determine the initial liquid level change rate;

[0024] Based on the initial liquid level change rate, a standard liquid level change rate is determined, wherein the initial liquid level change rate and the standard liquid level change rate have a preset mapping relationship.

[0025] In some feasible embodiments of the control method for the steam generating component described above, the mapping relationship between the initial liquid level change rate and the standard liquid level change rate is as follows:

[0026] X1 = K2 * X0,

[0027] Where X1 is the standard liquid level change rate, X0 is the initial liquid level change rate, and K2 is a constant.

[0028] In some feasible implementations of the control method for the steam generating component described above, the step of "determining whether to stop water replenishment based on the standard liquid level change rate and the actual liquid level change rate" includes:

[0029] If the actual liquid level change rate is greater than or equal to the standard liquid level change rate, then stop replenishing water; or

[0030] If the actual liquid level change rate is less than or equal to or less than the standard liquid level change rate, then continue to add water.

[0031] In some feasible embodiments of the control method for the steam generating assembly described above, the steam generating assembly further includes electric heating, and the control method further includes:

[0032] If it is determined that water needs to be added, the electric heater will be stopped.

[0033] The control method for the steam generating assembly provided by the present invention improves the accuracy and reliability of the liquid level detection of the steam generating assembly by linking the float-type liquid level device and the probe-type liquid level device for detection, thereby reducing the occurrence of malfunctions in the steam generating assembly and improving the efficiency of steam generation and the effect of clothing care.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal communication between two components.

[0046] like Figure 1 As shown, this embodiment of the invention provides a steam generating assembly 1, which includes a steam generating device 11, a water inlet device 12, and a drain device 13. The steam generating device 11 includes a steam box 111, a float-type liquid level device 112, a probe-type liquid level device 113, and an electric heater 114. The steam box 111 has a space for containing water. A water inlet 1111 is located on the upper side of the steam box 111, communicating with the water inlet device 12. A drain outlet 1112 is located on the lower side of the steam box 111, communicating with the drain device 13. The steam box 111 also has a steam port, which communicates with the garment care chamber 21 of the garment care device 2, allowing the steam generated in the steam box 111 to be delivered into the garment care device 2. The float-type liquid level device 112 is used to detect the liquid level of the water in the steam box 111. The probe-type liquid level device 113 is used to detect the liquid level value of the water in the steam box 111. An electric heater 114 is located at the bottom inner part of the steam box 111 to heat the water inside the steam box 111 to generate steam. The electric heater 114 is specifically a resistance heater, an electromagnetic heater, or an infrared heater. A water inlet device 12 is connected to a water inlet 1111 to allow water to enter the steam box 111. The water inlet device 12 is specifically a water pump and / or a water inlet valve. A drain device 13 is connected to a drain outlet 1112 to drain water from the steam box 111. The drain device 13 is specifically a drain pump and / or a drain valve.

[0047] Continue to refer to Figure 1The float-type liquid level device 112 includes a float element 1121, a detection tube 1122, and a detection module. The detection tube 1122 is disposed inside the steam box 111 and is connected to the interior of the steam box 111 to form a communicating vessel structure, so that the liquid level of the water in the detection tube 1122 is the same as the liquid level of the water in the steam box 111. The float element 1121 is placed inside the detection tube 1122. Since the detection tube 1122 and the steam box 111 are communicating vessels, the float element 1121 can move up and down in the detection tube 1122 as the liquid level of the water in the steam box 111 changes. The float element 1121 can be sensed and detected by the detection module, which detects the liquid level of the water in the steam box 111 through the float element 1121.

[0048] Continue to refer to Figure 1 Furthermore, the detection module includes a first detection module 1123 and a second detection module 1124. The first detection module 1123 is configured to correspond to the preset low liquid level of the steam box 111, and the second detection module 1124 is configured to correspond to the preset high liquid level of the steam box 111. The second detection module 1124 is located above the first detection module 1123, and the height of the preset high liquid level is greater than the height of the preset low liquid level. With the above configuration, the float-type liquid level device 112 can detect the preset low liquid level and the preset high liquid level of the water in the steam box 111.

[0049] Continue to refer to Figure 1The probe-type liquid level device 113 includes a probe element 1131, which extends into the steam box 111 to detect the liquid level of the water in the steam box 111. It should be noted that the probe-type liquid level device 113 detects liquid level changes based on the difference in conductivity or specific physical effects between the liquid and the probe element 1131. The conductivity of a liquid refers to its ability to conduct electricity, i.e., the ability of ions or electrons to flow in the liquid; different liquids have different conductivity, and even for the same liquid, its conductivity will change with concentration or temperature. When the liquid is not in contact with the probe element 1131, the circuit of the probe-type liquid level device 113 is in an open circuit state, and the current is almost zero; as the liquid gradually rises and comes into contact with the probe element 1131, the liquid becomes part of the circuit of the probe-type liquid level device 113, the conductivity of the circuit increases, and current begins to flow. As the liquid level rises further, more liquid contacts the probe element 1131, further enhancing the conductivity of the circuit in the probe-type liquid level device 113, and the current increases accordingly. The circuit in the probe-type liquid level device 113 measures the change in current and converts it into a readable liquid level value. This embodiment of the invention, by setting up the probe-type liquid level device 113, enables the steam generating assembly 1 to detect the liquid level value of the water in the steam box 111 during steam generation. This solves the problem of low detection accuracy caused by the boiling state of the water in the existing float-type liquid level device 112 during steam generation, thus improving the accuracy and reliability of liquid level detection in the steam generating assembly 11.

[0050] The steam generating assembly 1 provided in this embodiment of the invention, by incorporating a float-type liquid level device 112 and a probe-type liquid level device 113, enables the steam generating assembly 1 to determine the liquid level status of the water in the steam box 111 based on the detection results of two different types of liquid level detection devices, thereby improving the accuracy and reliability of liquid level detection in the steam generating assembly 1. Furthermore, based on the aforementioned high accuracy and high reliability of liquid level detection results, the steam generating assembly 1 provided by this invention can selectively adjust the opening and closing state of the water inlet device 12, thereby reducing the possibility of malfunction in the steam generating assembly 1 and improving the efficiency of steam generation and the effect of clothing care.

[0051] This invention also provides a control method for a steam generating assembly 1, wherein the steam generating assembly 1 is the steam generating assembly 1 described above, and the control method includes the following steps:

[0052] S100, water begins to enter when the steam box 111 is emptied.

[0053] Specifically, the steam box 111 is emptied of water by opening the drainage device 13, thus placing the steam box 111 in an empty state. After the water in the steam box 111 is emptied, the float-type liquid level device 112 and the probe-type liquid level device 113 are zero-point calibrated to reduce detection errors. After the float-type liquid level device 112 and the probe-type liquid level device 113 have been calibrated, the steam box 111 is filled with water by opening the water inlet device 12.

[0054] S200, during water intake, when the float-type liquid level device 112 detects that the water in the steam box 111 has reached a preset low liquid level, the first liquid level value detected by the probe-type liquid level device 113 is obtained.

[0055] Specifically, during the water intake of the steam box 111, when the first detection module 1123 of the float-type liquid level device 112 detects that the water in the steam box 111 has reached a preset low liquid level through the float component 1121, it obtains the first liquid level value detected by the probe-type liquid level device 113.

[0056] S300, during water intake, when the float-type liquid level device 112 detects that the water in the steam box 111 has reached a preset high liquid level, the second liquid level value detected by the probe-type liquid level device 113 is obtained.

[0057] Specifically, during the water intake of the steam box 111, when the second detection module 1124 of the float-type liquid level device 112 detects that the water in the steam box 111 has reached a preset high liquid level through the float component 1121, it obtains the second liquid level value detected by the probe-type liquid level device 113.

[0058] S400 determines the standard liquid level change rate based on the first liquid level value and the second liquid level value.

[0059] Step S400 specifically includes:

[0060] S410, based on the first liquid level value and the second liquid level value, determine the initial liquid level change rate.

[0061] Specifically, the initial liquid level change rate is determined by the following formula:

[0062] X0 = (L2 - L1) / L1;

[0063] Where X0 is the initial liquid level change rate, L1 is the first liquid level value, and L2 is the second liquid level value.

[0064] As an example, if the first liquid level value L1 is 30 and the second liquid level value L2 is 120, then the initial liquid level change rate X0 is: X0=(L2-L1) / L1=(120-30) / 30=3.

[0065] S420, based on the initial liquid level change rate, determines the standard liquid level change rate, wherein there is a preset mapping relationship between the initial liquid level change rate and the standard liquid level change rate.

[0066] It should be noted that the water temperature during the water intake period is different from that during the water replenishment period. The water during the water intake period is at room temperature, while the steam box 111 during the water replenishment period will retain the high-temperature water from the steam generation period. Although the water added to the steam box 111 during the water replenishment period is at room temperature, the temperature after mixing with the remaining high-temperature water is still higher than room temperature, and there is still a temperature difference between the two. Therefore, their electrical conductivity is different. In order to reduce the detection error caused by the probe-type liquid level device 113 due to the different electrical conductivity, this invention determines the standard liquid level change rate based on the initial liquid level change rate, thereby calibrating the initial liquid level change rate, which improves the accuracy and reliability of the liquid level detection of the steam generating component 1, reduces the occurrence of malfunctions of the steam generating component 1, and is conducive to improving the efficiency of steam generation and the effect of clothing care.

[0067] Specifically, the mapping relationship between the initial liquid level change rate and the standard liquid level change rate is as follows:

[0068] X1 = K2 * X0,

[0069] Where X1 is the standard liquid level change rate and K2 is a constant.

[0070] As an example, if the constant K2 is 0.7 and the initial liquid level change rate X0 is 3, then the standard liquid level change rate X1 is: X1 = K2 * X0 = 0.7 * 3 = 2.1.

[0071] It should be noted that since the water temperature during the water intake period and the water temperature during the water replenishment period are different, the specific value of the constant K2 can be adjusted according to the difference in conductivity between the two, thereby reducing the impact of the detection error caused by the conductivity of the water in the probe-type liquid level device 113.

[0072] S500, the first standard liquid level value of the probe-type liquid level device 113 is determined based on the first liquid level value, and the first liquid level value and the first standard liquid level value have a preset mapping relationship.

[0073] It should be noted that the water state during water intake is different from that during steam generation. During water intake, the water is at room temperature and the liquid surface is static, while during steam generation, the water is at high temperature and the liquid surface fluctuates due to boiling. Therefore, there are differences in conductivity and liquid surface state between the two. In order to reduce the detection error of the probe-type liquid level device 113, this invention determines a first standard liquid level value based on the first liquid level value, thereby calibrating the first liquid level value. This improves the accuracy and reliability of liquid level detection of the steam generating component 1, reduces the occurrence of malfunctions in the steam generating component 1, and helps to improve the efficiency of steam generation and the effect of clothing care.

[0074] Specifically, the mapping relationship between the first liquid level value and the first standard liquid level value is as follows:

[0075] B1 = K1 * L1,

[0076] Where B1 is the first standard liquid level value and K1 is a constant.

[0077] As an example, if the constant K1 is 1.2 and the first liquid level value L1 is 30, then the first standard liquid level value B1 is: B1 = K1 * L1 = 1.2 * 30 = 36.

[0078] It should be noted that since the water temperature during water intake and the water temperature during steam generation are different, the specific value of the constant K1 can be adjusted according to the difference in conductivity between the two, thereby reducing the impact of the detection error caused by the conductivity of the water in the probe-type liquid level device 113.

[0079] S600 determines whether water replenishment is needed during steam generation based on the first standard liquid level value and the real-time detection value of the probe-type liquid level device 113.

[0080] Step S600 specifically includes:

[0081] S610a, if the real-time detection value is less than the first standard liquid level value, it indicates that the water level in the steam box 111 has reached or is close to the preset low liquid level, and the water level in the steam box 111 is low, so it is determined that water needs to be added; or

[0082] S620a, if the real-time detection value is greater than or equal to the first standard liquid level value, it means that the water in the steam box 111 has not reached the preset low liquid level and there is a lot of water in the steam box 111, so it is determined that no water replenishment is needed.

[0083] In some specific embodiments, step S600 specifically includes:

[0084] S610b, if the real-time detection value is less than or equal to the first standard liquid level value, it indicates that the water level in the steam box 111 has reached or is close to the preset low liquid level, and the water level in the steam box 111 is low, so it is determined that water needs to be added; or

[0085] S620b If the real-time detection value is greater than the first standard liquid level value, it means that the water in the steam box 111 has not reached the preset low liquid level and there is a lot of water in the steam box 111, so it is determined that no water replenishment is needed.

[0086] Furthermore, if it is determined that water needs to be added, the electric heater 114 will be stopped.

[0087] S700, during water replenishment, when the float-type liquid level device 112 detects that the water in the steam box 111 has reached a preset low liquid level, it acquires the third liquid level value detected by the probe-type liquid level device 113. When the float-type liquid level device 112 detects that the water in the steam box 111 has reached a preset high liquid level, it acquires the real-time liquid level value of the probe-type liquid level device 113.

[0088] Specifically, during the water replenishment period, when the first detection module 1123 of the float-type liquid level device 112 detects through the float component 1121 that the water in the steam box 111 has reached a preset low liquid level, it acquires the third liquid level value detected by the probe-type liquid level device 113; and when the second detection module 1124 of the float-type liquid level device 112 detects through the float component 1121 that the water in the steam box 111 has reached a preset high liquid level, it acquires the real-time liquid level value of the probe-type liquid level device 113.

[0089] S800 determines the actual liquid level change rate based on the third liquid level value and the real-time liquid level value.

[0090] Specifically, the actual rate of change of liquid level is determined by the following formula:

[0091] X2 = (L4 - L3) / L3;

[0092] Where X2 is the actual liquid level change rate, L3 is the third liquid level value, and L4 is the real-time liquid level value.

[0093] As an example, if the third liquid level value L3 is 32 and the real-time liquid level value L4 is 140, then the actual liquid level change rate X2 is: X2=(L4-L3) / L3=(140-32) / 32=3.38.

[0094] The S900 determines whether to stop replenishing water based on the standard liquid level change rate and the actual liquid level change rate.

[0095] Step S900 specifically includes:

[0096] S910a, if the actual liquid level change rate is greater than the standard liquid level change rate, it indicates that the water in the steam box 111 has reached or is close to the preset high liquid level, and there is a lot of water in the steam box 111, so stop replenishing water; or

[0097] S920a, if the actual liquid level change rate is less than or equal to the standard liquid level change rate, it means that the water in the steam box 111 has not reached the preset high liquid level and the water in the steam box 111 is too little, so continue to add water.

[0098] In some specific embodiments, step S900 specifically includes:

[0099] S910b, if the actual liquid level change rate is greater than or equal to the standard liquid level change rate, it indicates that the water in the steam box 111 has reached or is close to the preset high liquid level, and there is a large amount of water in the steam box 111, so water replenishment should be stopped; or

[0100] S920b If the actual liquid level change rate is less than the standard liquid level change rate, it means that the water in the steam box 111 has not reached the preset high liquid level and the water in the steam box 111 is too little, so continue to add water.

[0101] It should be noted that the water used during the initial water intake is at room temperature, while the steam box 111 retains the high-temperature water from the steam generation period during the replenishment period. Although the water added to the steam box 111 during the replenishment period is at room temperature, the temperature after mixing with the remaining high-temperature water is still higher than room temperature. Therefore, there is still a difference in water temperature between the initial water intake and the replenishment period, resulting in different electrical conductivities. If the absolute difference between the first and second liquid level values ​​and the absolute difference between the third and real-time liquid level values ​​are used for comparison, and the decision to stop replenishment is based on this comparison, a significant error will occur. Compared to the above-mentioned method of using absolute differences for comparison, this embodiment of the invention uses a comparison between the standard liquid level change rate and the actual liquid level change rate. This reduces the impact of detection errors by the probe-type liquid level device 113, thereby improving the accuracy and reliability of liquid level detection in the steam generating component 1, reducing the possibility of malfunctions in the steam generating component 1, and ultimately improving the efficiency of steam generation and the effectiveness of garment care.

[0102] The control method for the steam generating component 1 provided in this embodiment of the invention improves the accuracy and reliability of the liquid level detection of the steam generating component 1 by associating the float-type liquid level device 112 and the probe-type liquid level device 113 for detection, thereby reducing the occurrence of malfunctions in the steam generating component 1 and improving the efficiency of steam generation and the effect of clothing care.

[0103] This invention also provides a control device, which includes a memory and a processor. The memory stores a computer program, and the processor is configured to execute the control method in any of the above-described technical solutions through the computer program.

[0104] It is understood that since the processor of the aforementioned control device is configured to execute the control method in any of the aforementioned technical solutions through a computer program, it possesses all the technical effects that can be obtained by the control method of the aforementioned steam generating component 1, which will not be elaborated here.

[0105] like Figure 2 As shown, this embodiment of the invention also provides a garment care device 2, which includes a garment care chamber 21 and a steam generating component 1 as described above. The garment care chamber 21 has a space for accommodating garments. The garment care chamber 21 is connected to the steam port of the steam generating component 1 via a connecting pipe 22, so that the steam generated by the steam generating component 1 can be delivered into the garment care chamber 21 to care for the garments. The garment care device 2 also includes the control device as described in any of the above technical solutions.

[0106] It is understood that since the garment care device 2 is equipped with the aforementioned steam generating component 1, it possesses all the technical effects of the aforementioned steam generating component 1. Furthermore, since the garment care device 2 is equipped with the aforementioned control device, it possesses all the technical effects that the aforementioned control device can obtain, which will not be elaborated here.
