[0031] When the above technical solution is adopted, when the wastewater level probe value obtained is lower than the actual wastewater amount in the wastewater box, it means that the conductivity of the wastewater in the wastewater box is relatively low, and the water level value detected by the probe is inaccurate. Therefore, the drainage pump is controlled to start and the water in the water storage box is discharged into the wastewater box. The conductivity of the water in the water storage box is higher than that of the wastewater in the wastewater box. Therefore, the water in the two water boxes is mixed in the wastewater box to neutralize the conductivity, which can increase the conductivity of the water in the wastewater box, thereby improving the accuracy of the water level detection by the wastewater level probe and preventing overflow.

Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the term "connection" should be understood in a broad sense. For example, it can mean a fixed connection, a detachable connection, or an integral connection; it can mean a mechanical connection; it can mean a direct connection, an indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0042] Specifically, refer to Figure 3 and Figure 4 The clothing care machine of the present invention includes a cabinet 1, a clothing care cavity 11 is provided in the cabinet 1, and clothes are hung in the clothing care cavity 11. The clothing care machine also includes a drying module and a steam generating device. The drying module includes a heater and a drying fan. After the heater heats the air, the drying fan blows the heated air into the care cavity 11 for drying the clothes. The steam generating device is arranged in the cabinet 1 and sends steam into the care cavity 11 through the steam outlet 12 to perform steam care on the clothes.

[0043] The clothing care machine further includes a water storage box 3, a wastewater box 4, and a steam water box 21. The steam water box 21 is connected to the steam generator to supply water to the steam generator. The care chamber 11 is provided with a water return port, which is connected to the wastewater box 4. The wastewater box 4 is used to collect condensed water in the care chamber 11. The water storage box 3 and the wastewater box 4 are connected by a pipeline. The pipeline is provided with a drain pump 5. The drain pump 5 is configured to enable bidirectional drainage. The drain pump 5 can drain wastewater from the wastewater box 4 into the water storage box 3 to prevent overflow of the wastewater box 4, and can also drain water from the water storage box 3 into the wastewater box 4 to improve the conductivity of the water in the wastewater box 4. However, it should be noted that the present invention does not impose any restrictions on the specific structure of the drain pump 5. The one bidirectional drain pump 5 in the present invention can also be replaced by two unidirectional drain pumps, which respectively control the water storage box 3 to drain into the wastewater box 4 and the wastewater box 4 to drain into the water storage box 3. Those skilled in the art can make their own settings as needed, and all such configurations fall within the scope of protection of the present invention. Furthermore, the water storage box 3 and the steam water box 21 are connected by a pipeline, and a water inlet pump 6 is provided on the pipeline, so that the water in the water storage box 3 can be discharged into the steam water box 21 after the water inlet pump 6 is turned on.

[0044] The water storage box 3 is provided with a water level probe 31 for detecting the water level therein, and the waste water box 4 is provided with a waste water level probe for detecting the water level therein. However, it should be noted that the present invention does not impose any limitations on the structure, location, and detection range of the water level probe 31 and the waste water level probe. Those skilled in the art may determine the configurations thereof as needed, and all such configurations fall within the scope of the present invention.

[0045] Further, refer to Figure 4 In order to improve the detection accuracy, the wastewater level probe includes a low water level probe 41 and a high water level probe 42. The lowest threshold value of the low water level probe 41 (ie, the first threshold value, Figure 4 The position indicated by L1 in FIG4 is lower than the lowest threshold value (ie, the second threshold value, Figure 4 The second threshold value is greater than the first threshold value.

[0046] Furthermore, the clothing care machine also includes a controller, which can obtain the values ​​on the water level probe 31, the low water level probe 41 and the high water level probe 42, and the controller can also control the operation of the steam generating device, the operation of the drying module and the start and stop of the drainage pump 5. Those skilled in the art can understand that the present invention does not impose any restrictions on the specific structure and model of the controller, and the technicians can set the structure and model of the controller according to actual usage requirements.

[0047] like Figure 1As shown, in order to solve the problem of overflow caused by misjudgment of the water level probe of the clothing care machine when the water conductivity is low, the control method of the clothing care machine of the present invention mainly includes the following steps:

[0048] Step S10: Obtaining the wastewater level probe value;

[0049] Step S20: When the wastewater level probe value is lower than the actual wastewater volume, the drainage pump is controlled to start to drain the water in the water storage box into the wastewater box.

[0050] When the wastewater level probe value obtained is lower than the actual wastewater volume in the wastewater box 4, it means that the conductivity of the wastewater in the wastewater box 4 is relatively low, and the water level value detected by the probe is inaccurate. Therefore, the drainage pump 5 is controlled to start and the water in the water storage box 3 is discharged into the wastewater box 4. The water conductivity in the water storage box 3 is higher than the wastewater in the wastewater box 4. Therefore, after the water in the two water boxes is mixed and neutralized in the wastewater box 4, the conductivity of the water in the wastewater box 4 can be increased, thereby improving the accuracy of the water level detection by the wastewater level probe and preventing overflow.

[0051] like Figure 2 As shown, in a possible implementation manner, the control method of the clothing care machine specifically includes the following steps:

[0052] Step S31: After controlling the clothing care machine to run the drying function or the steam function, the drainage pump is controlled to drain the water for a time period T1 to empty the waste water in the waste water box.

[0053] When the clothing care machine operates a function that can generate condensed water, such as a drying function or a steam function, the condensed water is discharged into the waste water box 4 for collection. After the clothing care machine operates the drying function or the steam function, the drain pump 5 is turned on to discharge all the waste water into the water storage box 3 to empty the waste water in the waste water box 4. However, it should be noted that the drying function or the steam function can also be replaced with other functions that can generate condensed water. Those skilled in the art can set it as needed, and it falls within the scope of protection of the present invention. The specific value of the T1 time length can be set by those skilled in the art as long as the waste water can be emptied, and it falls within the scope of protection of the present invention.

[0054] Step S32: After the waste water box is emptied, the clothing care machine runs the drying function or the steam function for T2 time and obtains the low water level probe value in the waste water box.

[0055] After the wastewater in the wastewater box 4 is drained, the clothing care machine operates the function capable of generating condensed water for a period of time T2, and the actual water level in the wastewater box 4 exceeds the first threshold of the low water level probe 41. The T2 period is set by those skilled in the art based on actual needs. As long as the actual water level in the wastewater box 4 exceeds the first threshold of the low water level probe 41 after the T2 period, the present invention is protected.

[0056] Step S33: Determine whether the low water level probe value is greater than the first threshold.

[0057] If step S33 is not established, execute step S34;

[0058] Step S34: obtaining the water level probe value in the water storage box;

[0059] Step S35: Determine whether the water level probe value exceeds the third threshold value.

[0060] If the judgment result of step S35 is true, then step S361 is executed:

[0061] Step S361: Control the drainage pump to start and drain the water in the water storage box into the waste water box R1 water volume;

[0062] If the judgment result of step S35 is not established, step S362 is executed;

[0063] Step S362: Control the drain pump to drain for a period of time T3 to empty the waste water in the waste water box.

[0064] If the low water level probe value is greater than the first threshold value, it means that the low water level probe value is lower than the first threshold value, and the first threshold value is lower than the actual water level, that is, the low water level probe value is lower than the actual water level, which means that the conductivity of the wastewater is relatively low, the low water level probe value is inaccurate, and the water level in the wastewater box 4 cannot be accurately detected. Therefore, the drain pump 5 is turned on to drain the water in the water storage box 3 into the wastewater box 4 by a volume R1, so as to mix the water in the water storage box 3 with the water in the wastewater box 4 to increase the conductivity of the water in the wastewater box 4, thereby improving the water level detection accuracy of the probe in the wastewater box 4. Among them, the water volume R1 is a set value, which can be set by those skilled in the art based on experimental data or empirical formulas. The present invention does not impose any restrictions on R1 and all fall within the scope of protection of the present invention.

[0065] Furthermore, before step S361, it is determined whether the water level probe value in the water storage box 3 is higher than the third threshold value ( Figure 3 If the water level probe value in the water storage box 3 is less than or equal to the third threshold value, it means that the water conductivity in the water storage box 3 is relatively high, which meets the requirement of improving the conductivity of the wastewater, and the water can be drained from the water storage box 3 to the wastewater box 4. If the water level probe value in the water storage box 3 is less than or equal to the third threshold value, it means that the water conductivity in the water storage box 3 is also relatively low, which cannot meet the requirement of improving the conductivity of the water in the wastewater box 4. In this case, all the wastewater in the wastewater box 4 is directly drained into the water storage box 3 to prevent overflow. Among them, the time T3 is set to the time length that can drain the maximum amount of water in the wastewater box 4.

[0066] After step S361, execute step S37;

[0067] Step S37: Re-determine whether the low water level probe value is greater than the first threshold value.

[0068] If the judgment result of step S37 is established, step S38 is executed;

[0069] If the judgment result of step S37 is not established, step S362 is executed;

[0070] If the judgment result of step S33 is established, step S38 is executed;

[0071] Step S38: When the high water level probe value is greater than the second threshold, the drain pump is controlled to drain water for a time period of T4 to drain the water in the waste water box into the water storage box.

[0072] After R1 amount of water is discharged from the water storage box 3 into the wastewater box 4, the low water level probe value in the wastewater box 4 is re-determined to be greater than a first threshold value. If the low water level probe value is greater than the first threshold value, it indicates that the wastewater conductivity has increased, the water level detection has returned to normal, and the water level probe is correctly detecting the water level. Therefore, the wastewater is discharged into the water storage box 3 only when the water level in the wastewater box 4 reaches a relatively high water level, that is, the high water level probe value is detected. When the high water level probe value is greater than a second threshold value, the drain pump 5 is controlled to operate for a duration T4 to partially or completely discharge the water in the wastewater box 4 into the water storage box 3. The specific value of the T4 duration can be set by those skilled in the art and falls within the scope of protection of the present invention.

[0073] If step S37 or S33 is established, and the low water level probe value is greater than the first threshold value, it indicates that the conductivity of the wastewater is normal, and the water level probe in the wastewater box 4 can accurately detect the water level. It is not necessary to drain water from the water storage box 3 to the wastewater box 4. Instead, when the high water level probe value is greater than the second threshold value, the drainage pump is directly controlled to start and drain the water in the wastewater box 4 into the water storage box 3.

[0074] When the water level in the waste water box 4 reaches the maximum threshold, part or all of the waste water is discharged into the water storage box 3. Compared with directly discharging all the water in the waste water box 4 into the water storage box 3 after step S33, the drainage frequency can be reduced, the energy consumption and the motor loss can be reduced.

[0075] Step S39: Determine whether the total time the clothing care machine runs the drying function or the steam function reaches T3; wherein T3 ≥ T2;

[0076] If the judgment result of step S39 is true, the program ends;

[0077] If the judgment result of step S39 is not established, return to step S33.

[0078] When the total time duration of the drying function or the steam function of the clothing care machine reaches T3, the program ends. If T3 is not reached, the program returns to step S33 to continue judging the low water level probe value.

[0079] It should be noted that in the above embodiment, step S37 can be eliminated, and step S38 can be directly executed after directly mixing water sufficient to increase the conductivity into the wastewater box 4. Those skilled in the art can set the values ​​as needed, and all of them fall within the scope of protection of the present invention. In addition, the specific values ​​of the first to third thresholds can be set by those skilled in the art based on experimental data or based on empirical formulas, for example, the first threshold is 20 mm, 30 mm, 50 mm, the second threshold is 80 mm, 90 mm, 100 mm, and the third threshold is 100 mm, 200 mm, 300 mm, etc. The present invention does not impose any restrictions on the specific values ​​of the first to third thresholds, and all of them fall within the scope of protection of the present invention.

[0080] To sum up, the control method of the clothing care machine of the present invention verifies whether the water level probe in the wastewater box 4 can correctly detect the water level in the wastewater box 4 by discharging a set amount of water into the wastewater box 4, and then discharges the water in the water storage box 3 into the wastewater box 4 when the water conductivity in the wastewater box 4 is relatively low. By mixing the water in the water storage box 3 with the water in the wastewater box 4, the water conductivity in the wastewater box 4 is increased. If step S33 shows that the water conductivity in the wastewater box 4 is normal or the water conductivity in the wastewater box 4 returns to normal after step S361, the wastewater is discharged into the water storage box 3 when the water amount in the wastewater box 4 is greater than the second threshold value to prevent overflow, reduce the start and stop frequency of the drainage pump 5, save energy consumption, and reduce motor loss.

[0081] As stated in the first paragraph of this section, the above implementation mode is only used to illustrate the principles of the present invention and is not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above structure so that the present invention can be applied to more specific application scenarios.

[0084] Although the above-mentioned embodiments are described in the above-mentioned order, those skilled in the art can understand that, in order to achieve the effects of the embodiments, the different steps do not have to be executed in such an order, and can be executed simultaneously (in parallel) or in a reversed order.
