Technical Field

[0001] This invention relates to the field of clothing processing equipment technology, and specifically provides a clothing care machine and its control method. Background Technology

[0002] With the rapid development of technology, garment care machines are gradually entering people's lives. A garment care machine is a household appliance that uses steam, vibration, and hot air to care for clothes. Existing garment care machines are equipped with air vents on their inner walls, through which steam and hot air enter the inner cavity of the machine to care for the clothes.

[0003] In the existing technology, the water system in garment care equipment is either a built-in water tank or an external water inlet pipe. If it only has a built-in water tank, the user needs to add water manually during use. If it only has a water inlet pipe, the equipment cannot be used in areas without a pipe. If the user wants to switch to another water inlet method, the current garment care machine cannot support it.

[0004] Accordingly, there is a need in the art for a garment care machine and its control method to solve the above-mentioned technical problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problem, namely, in the prior art, the water system in clothing care equipment is either a self-contained water tank or an external water inlet pipe solution, which makes it difficult for users to switch.

[0012] The water tank is equipped with a first water level detection device.

[0013] The steam box is equipped with a second water level detection device.

[0014] In a specific embodiment of the aforementioned garment care machine, the first water level detection device includes a high-level float, a middle-level float, and a low-level float, which are respectively positioned at a third height, a second height, and a first height within the water tank.

[0015] The second water level detection device is a water level steel needle, which is set at a preset water level height inside the steam box.

[0016] Secondly, the present invention also provides a control method for a garment care machine, wherein the garment care machine is the garment care machine described in the above embodiments, and the control method includes,

[0018] If the initial water level in the steam box does not reach the preset water level, obtain the initial water level information in the water tank.

[0019] If the initial water level in the tank has not reached the first height value, the first valve will open.

[0020] After the first preset time has elapsed since the first valve was opened, the real-time water level information of the water tank is obtained.

[0021] If the real-time water level in the tank is higher than the second height value, the current water inlet structure is determined to be a water inlet pipe, and the first valve body remains open.

[0022] When the real-time water level in the tank reaches the third height value, the first valve body is closed and the second valve body is opened. The third height value must be greater than the second height value, which in turn must be greater than the first height value.

[0023] After the second preset time has elapsed since the second valve was opened, the real-time water level information of the steam box is obtained.

[0024] If the real-time water level in the steam box reaches the preset water level, close the second valve and start the steam program.

[0025] In a specific embodiment of the control method for the aforementioned garment care machine, a first flow meter and a first alarm device are further installed in the water inlet pipe. The first flow meter is configured to acquire the flow rate value of the water inlet pipe. After the step "acquiring the real-time water level information of the water tank after a first preset time following the opening of the first valve body", the control method further includes...

[0026] If the real-time water level in the tank is higher than the first height value but lower than the second height value, the current water inlet structure is determined to be an inlet pipe, and the flow rate of the inlet pipe is obtained.

[0027] When the flow rate of the inlet pipe is less than the first preset flow rate, the first alarm device is controlled to issue an abnormal water inlet alarm for the water tank.

[0031] If the real-time water level in the tank has not yet reached the first height, the current water inlet structure is determined to be a water tank.

[0032] The user is prompted to add water to the third height value through the second inlet and open the second valve.

[0033] In a specific embodiment of the control method for the aforementioned garment care machine, after the step of "obtaining the initial water level information in the steam box," the control method further includes,

[0034] When the initial water level in the steam box reaches the preset water level height, the steam program is started directly.

[0035] In a specific embodiment of the control method for the aforementioned garment care machine, after the step of "obtaining the initial water level information in the water tank," the control method further includes,

[0036] If the initial water level in the water tank reaches the first height value, the second valve body is opened, and the real-time water level information in the steam box is obtained.

[0037] After the second preset time has elapsed since the second valve was opened, the real-time water level information of the water tank is obtained.

[0038] If the real-time water level in the steam box reaches the preset water level, close the second valve and start the steam program.

[0039] Specifically, when the initial water level in the water tank reaches the first height value, the water volume in the water tank is not less than the volume of the steam box.

[0040] In a specific embodiment of the control method for the aforementioned garment care machine, a second flow meter and a second alarm device are further provided in the connecting pipeline. The second flow meter is configured to acquire the flow rate value of the connecting pipeline. After the step "acquiring the real-time water level information of the steam box after the second valve body is opened for a second preset time", the control method further includes...

[0041] If the real-time water level in the steam box does not reach the preset water level, obtain the flow rate value of the connecting pipeline.

[0042] When the flow rate of the connecting pipeline is less than the second preset flow rate value, the second alarm device is controlled to issue an abnormal water inlet alarm for the steam box.

[0043] In a specific embodiment of the control method for the aforementioned garment care machine, the control method further includes,

[0044] When the flow rate of the connecting pipeline is greater than or equal to the second preset flow rate value, the second alarm device is controlled to issue a steam box leakage alarm.

[0045] Based on the above technical solution, this invention proposes a garment care machine that simultaneously incorporates a water tank and an external water inlet pipe. This garment care machine is equipped with a first water inlet connected to the water inlet pipe and a second water inlet for manually adding water to the tank. This allows the care program to operate normally regardless of whether external water inlet or outlet pipes are connected, thus meeting different usage scenarios and improving the versatility of the equipment. Furthermore, based on this structure, this invention proposes a control method for the garment care machine, enabling it to automatically determine the current water inlet mode without requiring manual setting by the user.

[0050] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, although this specific embodiment is described in conjunction with the application of a water tank inlet / outlet method to a garment care machine, the control method protected by this invention can obviously also be used in other devices. Such changes in application scenarios do not depart from the basic principles of the invention and fall within the scope of protection of the invention.

[0051] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0052] With the rapid development of technology, garment care machines are gradually entering people's lives. A garment care machine is a household appliance that uses steam, vibration, and hot air to care for clothing. Existing garment care machines all have air vents on their inner walls, through which steam and hot air enter the machine's cavity to care for the clothes. In current technology, the water system in garment care equipment is either a built-in water tank or an external water inlet pipe. If it only has a built-in water tank, the user needs to manually add water during use. If it only has a water inlet pipe, the device cannot be used in areas without a pipe. If the user wants to switch to another water inlet method, the current garment care machine cannot support it.

[0053] See Figure 1 , Figure 1 This is a schematic diagram of the overall structure of the garment care machine provided by the present invention. Figure 1As shown, the garment care machine includes a water tank 1, a water inlet pipe 2, a steam box 3, a connecting pipe 4, a first valve body 5, and a second valve body 6. The water tank 1 is located inside the garment care machine and has a first water inlet 11, a second water inlet 12, and a water outlet 13. The water inlet pipe 2 is connected to the first water inlet 11 of the water tank. The connecting pipe 4 is located between the steam box 3 and the water outlet 13 of the water tank 1. The first valve body 5 is located on the water inlet pipe 2, and the second valve body 6 is located on the connecting pipe 4. A first water level detection device 7 is installed inside the water tank 1, and a second water level detection device 8 is installed inside the steam box 3. Based on the above structural configuration, the present invention proposes a garment care machine that simultaneously includes a water tank 1 and an external water inlet pipe 2. The garment care machine is equipped with a first water inlet 11 connected to the water inlet pipe 2 and a second water inlet 12 for manually adding water to the water tank 1. This allows the garment care program to run normally regardless of whether an external water inlet or outlet pipe is connected, thereby meeting different usage scenarios and improving the versatility of the equipment.

[0054] Specifically, in this preferred embodiment, the water tank 1 is detachably installed inside the garment care machine, so that when the water tank 1 is not connected to the water inlet pipe 2, the user can easily remove the water tank 1 to add water. It should be noted that the present invention does not impose any restrictions on the specific structure and installation location of the water tank 1, and those skilled in the art can set it according to actual usage needs.

[0055] It should be noted that the present invention does not impose any restrictions on the specific structure and setting position of the first water inlet 11 and the water inlet pipe 2, only that the connection size of the first water inlet 11 and the water inlet pipe 2 is compatible. Those skilled in the art can set it themselves according to actual usage requirements.

[0056] In this preferred embodiment, the second water inlet 12 is located at the top of the water tank 1, allowing the user to add water to the water tank 1 through the second water inlet 12. Simultaneously, the diameter of the second water inlet 12 is larger than a preset size to prevent water spillage during the process of adding water to the water tank 1 through the second water inlet 12. It should be noted that this invention does not impose any limitations on the preset size of the second water inlet 12; those skilled in the art can set it according to actual usage requirements.

[0057] In this preferred embodiment, the water outlet 13 is located at the bottom of the water tank 1, so that when water flows from the water tank 1 to the steam box 3, no water will remain inside the water tank 1, thus avoiding water accumulation in the water tank 1 due to the water outlet 13 being set too high, which would cause the water tank 1 to smell bad.

[0058] It should be noted that the present invention does not impose any restrictions on the specific structure and setting position of the first valve body 5 and the second valve body 6. It is only required that the first valve body 5 can control the flow or closure of the water inlet pipe 2 and the second valve body 6 can control the flow or closure of the connecting pipe 4. Those skilled in the art can set it according to actual usage requirements.

[0059] In this preferred embodiment, the first water level detection device 7 includes a high-level float 71, a middle-level float 72, and a low-level float 73, which are respectively positioned at a third height, a second height, and a first height within the water tank 1. It is understood that the low-level float 73 is used to detect whether the water level in the water tank 1 has reached the first height value, the middle-level float 72 is used to detect whether the water level in the water tank 1 has reached the second height value, and the high-level float 71 is used to detect whether the water level in the water tank 1 has reached the third height value. The second water level detection device 8 is a water level needle, which is positioned at a preset water level height within the steam box 3. Similarly, the water level needle can detect whether the water level in the steam box 3 has reached the preset water level height. It should be noted that this invention does not impose any limitations on the specific values ​​of the third height, the second height, the first height, and the preset water level height; those skilled in the art can set these values ​​according to actual usage requirements.

[0060] See Figure 2 , Figure 2 This is a flowchart of the control method for the garment care machine provided by the present invention. Figure 2 As shown, to address the problem in existing garment care devices where the water system is either a self-contained water tank or an external water inlet pipe, making it difficult for users to switch between the two solutions, the present invention provides a control method for a garment care machine that includes...

[0061] S1: Obtain the initial water level information in the steam box.

[0062] S2: When the initial water level in the steam box has not reached the preset water level height, obtain the initial water level information in the water tank.

[0063] S3: If the initial water level in the tank has not reached the first height value, control the first valve to open.

[0064] S4: After the first preset time has elapsed since the first valve body was opened, obtain the real-time water level information of the water tank.

[0065] S5: If the real-time water level in the tank is higher than the second height value, determine that the current water inlet structure is a water inlet pipe, and keep the first valve open.

[0066] S6: When the real-time water level in the water tank reaches the third height value, close the first valve body and open the second valve body. The third height value must be greater than the second height value, which in turn must be greater than the first height value.

[0067] S7: After the second preset time for opening the second valve body, obtain the real-time water level information of the steam box.

[0068] S8: If the real-time water level in the steam box reaches the preset water level, close the second valve and start the steam program.

[0069] When using the above technical solution, it is necessary to first determine the initial water level in the steam box when performing garment care. If the initial water level in the steam box does not reach the preset water level, it means that there is no water in the current steam box, and the steam program cannot be entered at this time. Water needs to be added to the steam box first. During the process of adding water to the steam box, it is necessary to first determine whether there is water in the garment care machine's water tank. If the initial water level in the tank has not reached the first height value, it indicates that there is no water in the tank at this time. In this case, it is necessary to determine the water inlet structure of the tank. After the first valve is opened for a first preset time, if the real-time water level in the tank is higher than the second height value, it indicates that water is entering the tank through the first valve, meaning the water inlet structure is now a water inlet pipe. When the real-time water level reaches the third height value, it indicates that the tank is full. At this point, the first valve can be closed to stop adding water to the tank, and the second valve can be opened to add water to the steam box through the tank. After the second valve is opened for a second preset time, if the real-time water level in the steam box reaches the preset water level height, it indicates that the steam box is fully filled, and the steam program can be started. The control method for the garment care machine provided by this invention can automatically determine the current water inlet mode of the water tank without requiring manual setting by the user, and automates the steam program accordingly.

[0070] In this preferred embodiment, the present invention does not impose any restrictions on the specific duration of the first preset time and the second preset time in the above steps. Those skilled in the art can set them according to actual usage needs. For example, the first preset time can be 1 minute, 2 minutes, 3 minutes, etc., and the second preset time can be 15 seconds, 30 seconds, 60 seconds, etc. The specific duration of the first preset time and the second preset time can be determined according to the volume of the water tank and the steam box.

[0071] In this preferred embodiment, the control method for the garment care machine provided by the present invention further includes,

[0072] S9: If the real-time water level in the tank is higher than the first height value but lower than the second height value, determine that the current water inlet structure is a water inlet pipe, and obtain the flow rate value of the water inlet pipe.

[0073] S10: When the flow rate of the inlet pipe is less than the first preset flow rate value, control the first alarm device to issue an abnormal water inlet alarm for the water tank.

[0074] S11: When the flow rate of the inlet pipe is greater than or equal to the first preset flow rate value, control the first alarm device to issue a water tank leakage alarm.

[0075] When using the above technical solution, if, after a first preset time following the opening of the first valve, the water level in the tank is above the first height but below the second height, it indicates that water is entering the tank through the first valve. This suggests that the water inlet structure is an inlet pipe. However, since the water level has not reached the second height, the inlet rate is too slow, requiring investigation of any abnormalities. The water flow rate in the inlet pipe is then assessed. If the flow rate is less than the first preset value, the inlet rate is abnormal, potentially indicating a blockage or insufficient water pressure. In this case, the first alarm device issues a water tank inlet abnormality alarm. Conversely, if the flow rate is greater than or equal to the first preset value, the inlet rate is normal, but a leak may be present. In this case, the first alarm device issues a water tank leak alarm. Through this technical solution, the present invention can directly determine the cause of any abnormal water tank inlet conditions, eliminating the need for manual troubleshooting and providing a better user experience.

[0076] It should be noted that the present invention does not impose any restrictions on the specific value of the first flow rate preset value, and technicians can set it themselves according to actual usage needs.

[0077] In this preferred embodiment, the control method for the garment care machine provided by the present invention further includes,

[0078] S12: If the real-time water level in the tank has not yet reached the first height, determine that the current water inlet structure is a water tank.

[0079] S13: Prompt the user to add water to the third height value through the second inlet and open the second valve body.

[0080] When using the above technical solution, if the real-time water level in the water tank still does not reach the first height after the first preset time of opening the first valve body, it means that no water enters the water tank through the first valve body. This indicates that the water tank is in the water tank at this time, and prompts the user to add water to the third height value through the second water inlet to avoid the water tank being short of water for a long time.

[0081] In this preferred embodiment, the control method for the garment care machine provided by the present invention further includes,

[0082] S14: When the initial water level in the steam box reaches the preset water level height, the steam program is started directly.

[0083] Understandably, when performing garment care, it is necessary to first determine the initial water level in the steam box. When the initial water level in the steam box reaches the preset water level height, it indicates that there is water in the steam box. At this point, the steam program can be started directly, thereby reducing the frequency of water intake or user refilling and thus speeding up the workflow.

[0084] In this preferred embodiment, the control method for the garment care machine provided by the present invention further includes,

[0085] S15: If the initial water level in the water tank reaches the first height value, open the second valve and obtain the real-time water level information in the steam box.

[0086] S7: After the second preset time has elapsed since the second valve body was opened, obtain the real-time water level information of the water tank.

[0087] S8: If the real-time water level in the steam box reaches the preset water level, close the second valve and start the steam program.

[0088] When using the above technical solution, when determining whether the water tank of the garment care machine has water, if the initial water level information in the water tank reaches the first...

[0089] A height value indicates that there is water in the water tank at this time. There is no need to add water to the water tank at this time. Simply open the second valve body to add water to the steam box through the water tank. After the second preset time of opening the second valve body, if the real-time water level information in the steam box reaches the preset water level height, it means that the steam box has been filled with water and the steam program can be started.

[0090] It is understood that the present invention limits the water volume in the water tank to no less than the volume of the steam box when the initial water level in the water tank reaches the first height value. This means that when the initial water level in the water tank reaches the first height value, the volume in the water tank is sufficient to make the water in the steam box reach the preset water level height, thus avoiding abnormal water filling of the steam box.

[0091] In this preferred embodiment, the control method for the garment care machine provided by the present invention further includes,

[0092] S16: If the real-time water level in the steam box does not reach the preset water level, obtain the flow rate value of the connecting pipeline.

[0093] S17: When the flow rate in the connecting pipeline is less than the second preset flow rate value, control the second alarm device to issue an abnormal water inlet alarm in the steam box.

[0094] S18: When the flow rate of the connecting pipeline is greater than or equal to the second preset flow rate value, control the second alarm device to issue a steam box leakage alarm.

[0095] When using the above technical solution, if the real-time water level in the steam box does not reach the preset water level after the second preset time following the opening of the second valve, it indicates that the water inlet rate of the steam box is too slow, and the current abnormality of the steam box needs to be investigated. At this time, the water flow rate in the connecting pipe is judged. If the flow rate in the connecting pipe is less than the second preset flow rate value, it indicates that the water inlet rate in the connecting pipe is abnormal, possibly due to blockage or insufficient water pressure. In this case, the second alarm device is controlled to issue a steam box water inlet abnormality alarm. If the flow rate in the connecting pipe is greater than or equal to the second preset flow rate value, it indicates that the water inlet rate in the connecting pipe is normal, but there may be a steam box leak. In this case, the second alarm device is controlled to issue a steam box leak alarm. Through the above technical solution, this invention can directly determine the cause of the abnormal state when the steam box experiences water inlet abnormality, eliminating the need for manual troubleshooting by the user and thus providing a better user experience.

[0096] It should be noted that the present invention does not impose any restrictions on the specific value of the second flow preset value, and technicians can set it themselves according to actual usage needs.

[0097] It should be noted that the above embodiments are merely used to illustrate the principles of the present invention and are 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.

[0098] Those skilled in the art will understand that the above-described control method for a garment care machine also includes other known structures, such as processors, controllers, and memories. These memories include, but are not limited to, random access memory (RAM), flash memory, read-only memory (ROM), programmable read-only memory (PROM), volatile memory, non-volatile memory, serial memory, parallel memory, or registers. Processors include, but are not limited to, CPLD / FPGA, DSP, ARM processors, and MIPS processors. To avoid unnecessarily obscuring the embodiments of this disclosure, these known structures are not shown in the accompanying drawings.

They can be executed simultaneously (in parallel) or in a reverse order. These simple variations are all within the protection scope of this invention.

However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments.

The user is prompted to add water to the third height value through the second inlet and open the second valve.

7. The control method according to claim 3, characterized in that, Following the step of "acquiring the initial water level information in the steam box", the control method further includes, When the initial water level in the steam box reaches the preset water level height, the steam program is started directly.

8. The control method according to claim 3, characterized in that, Following the step of "obtaining the initial water level information in the water tank", the control method further includes, If the initial water level in the water tank reaches the first height value, the second valve body is opened, and the real-time water level information in the steam box is obtained. After the second preset time has elapsed since the second valve was opened, the real-time water level information of the water tank is obtained. If the real-time water level in the steam box reaches the preset water level, close the second valve and start the steam program. Specifically, when the initial water level in the water tank reaches the first height value, the water volume in the water tank is not less than the volume of the steam box.

9. The control method according to claim 3 or claim 8, characterized in that, The connecting pipeline is also equipped with a second flow meter and a second alarm device. The second flow meter is configured to acquire the flow rate value of the connecting pipeline. After step "acquiring the real-time water level information of the steam box after the second valve body is opened for a second preset time", the control method further includes... If the real-time water level in the steam box does not reach the preset water level, obtain the flow rate value of the connecting pipeline. When the flow rate of the connecting pipeline is less than the second preset flow rate value, the second alarm device is controlled to issue an abnormal water inlet alarm for the steam box.

10. The control method according to claim 9, characterized in that, The control method also includes, When the flow rate of the connecting pipeline is greater than or equal to the second preset flow rate value, the second alarm device is controlled to issue a steam box leakage alarm.
