Description

Technical Field

[0001] This invention belongs to the field of household appliance technology, specifically, it relates to a control method for a clothing processing device and a clothing processing device. Background Technology

[0002] Washing machines, as one of the most widely used household appliances in daily life, have helped people get rid of the hassle of laundry and brought great convenience to their lives. However, existing washing machines generally consist of an outer drum and an inner drum that rotats inside the outer drum. The inner drum has multiple drain holes distributed on its wall. During the washing process, the washing water between the inner and outer drums is not utilized, resulting in waste. Furthermore, dirt generated by the clothes during washing enters the space between the inner and outer drums with the water flow and accumulates there. With prolonged use, this accumulation of dirt severely affects the washing effect, thus reducing the user experience. To solve these problems, a new type of washing machine with a perforated inner drum has been developed. The inner drum opening is equipped with an openable / closable inner drum door, forming an internal chamber that can independently hold the washing water. In this way, during washing and rinsing, the washing water is contained in the inner drum, leaving no water between the inner and outer drums, thus solving the problem of dirt accumulation between the inner and outer drums and saving washing water.

[0003] To achieve pressure balance within the drum, existing washing machines without perforated inner drums typically require an overflow vent that connects to the outside atmosphere. This ensures proper water intake and release of steam generated during heating. Over time, lint or other debris from washing clothes can clog the overflow vent, hindering water intake. More seriously, the steam generated by high-temperature heating cannot escape properly, potentially causing water or steam to overflow from the drum, resulting in reduced water volume or even scalding from the steam.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a control method and a garment processing device. By judging whether the overflow structure is in an abnormal working state, the user can promptly detect whether the overflow structure is in an abnormal working state and promptly clean the overflow structure in an abnormal working state. This achieves the purpose of ensuring normal water intake of the inner drum and normal discharge of high-temperature steam in the inner drum, and preventing water leakage and scalding problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0014] Further, step S3 includes:

[0015] Determine whether the water level detection value H is within the theoretical water level range of 0 to h1 corresponding to the set water inflow V1;

[0017] Furthermore, after determining that the overflow structure is in an abnormal working state due to blockage, the control method includes:

[0019] Furthermore, the secondary confirmation step includes:

[0020] Continue to introduce water into the non-porous inner cylinder until the set water inlet volume V2 is reached, and obtain the water level detection value H of the non-porous inner cylinder;

[0021] If the water level detection value H is not within the theoretical water level range of 0 to h2 corresponding to the set water inflow V2, then the overflow structure is confirmed to be in an abnormal working state due to blockage.

[0022] Furthermore, after confirming that the venting structure is in an abnormal working state due to blockage, stop water from entering the non-porous inner cylinder and prompt the user to clean the venting structure.

[0023] Furthermore, including:

[0024] If the water level detection value H obtained when the set water inlet volume V1 is within the theoretical water level range of 0 to h1, or if the water level detection value H obtained when the set water inlet volume V2 is within the theoretical water level range of 0 to h2, then continue to feed water into the non-porous inner drum until the water level in the non-porous inner drum reaches the washing water level.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0047] like Figure 1 and Figure 2 As shown, the present invention provides a control method for a garment processing device, the garment processing device including a non-perforated inner cylinder, the inner cylinder having an air overflow structure 5 communicating with the outside atmosphere, the control method including:

[0048] S1. The garment handling device executes the water inlet procedure, introducing water into the non-porous inner drum 1;

[0049] S2. When the water inlet reaches the set water inlet volume V, obtain the water level detection value H of the non-porous inner cylinder 1;

[0050] S3. Based on the water level detection value H of the non-porous inner cylinder 1, determine whether the overflow structure 5 is in an abnormal working state.

[0051] In the embodiments of the present invention, the above judgment enables users to promptly detect whether the overflow structure 5 is in an abnormal working state, and to promptly clean the overflow structure 5 in an abnormal working state, ensuring normal water intake in the inner cylinder and normal discharge of high-temperature steam in the inner cylinder, preventing water leakage and scalding problems.

[0052] The clothing handling device is a washing machine, and further, the washing machine can be a drum washing machine. The drum washing machine includes: a non-perforated inner drum 1 for receiving the clothes to be washed and the washing water; an inner drum cover for sealing the opening of the non-perforated inner drum 1; an overflow structure 5 provided on the non-perforated inner drum 1 to connect the non-perforated inner drum 1 with the external environment; a first sensor, the detection probe of the first sensor being located inside the non-perforated inner drum 1 for acquiring the water level detection value H of the non-perforated inner drum 1; and a control unit, the control unit being provided with a theoretical water level value range corresponding to the water inlet volume V; the control unit determining whether the overflow structure is in an abnormal working state based on whether the water level detection value H acquired when the water inlet volume V is within the corresponding theoretical water level value range.

[0053] The inflow rate V is linearly related to the theoretical water level h, and each inflow rate V corresponds to a theoretical water level or a range of theoretical water levels.

[0054] The inflow rate V can be any single inflow rate. Multiple inflow rates V can be multiple discontinuous inflow rate coordinate points, used to form a linear curve between the inflow rate V and the theoretical water level h, forming the first type of curve.

[0055] Multiple inflow rates V can be multiple consecutive inflow rate coordinate points, used to form a linear curve of inflow rate V and theoretical water level h, forming a second type of curve;

[0056] The theoretical water level h corresponding to any given inflow rate V can be found from the linear curve of inflow rate V and theoretical water level h.

[0057] In order to measure the water pressure value P inside the non-porous inner cylinder 1 more accurately, the detection probe of the first sensor is set at a relatively low position at the bottom of the non-porous inner cylinder 1 to prevent the first sensor from being unable to detect the water pressure value P inside the non-porous inner cylinder 1 when the water level is too low.

[0058] The water pressure value P inside the non-porous inner cylinder 1 can be detected by the first sensor, and the control unit converts the water pressure value P inside the non-porous inner cylinder 1 detected by the first sensor into a water level detection value H.

[0059] More specifically, the bottom of the inner cylinder has an inner cylinder shaft 2, the inner cylinder shaft 2 is hollow to form a water inlet channel 21, the bottom of the inner cylinder is provided with a water inlet nozzle 3 located inside the inner cylinder, the water inlet nozzle 3 has a water inlet channel and an overflow channel 51 formed inside, the water inlet of the water inlet channel is connected to the water inlet channel 21, and the water outlet of the water inlet channel is connected to the inside of the inner cylinder to allow water to enter the inner cylinder; the overflow channel 51 connects the inside of the inner cylinder to the outside atmosphere to balance the pressure inside the inner cylinder and the outside environment; the water inlet end of the water inlet channel 21 is connected to the water inlet pipe, and the water inlet end of the water inlet pipe is connected to a water source or to a detergent dispensing device. The overflow structure 5 of this application includes the aforementioned overflow channel 51.

[0060] A flow meter is installed on the inlet pipe to monitor the inlet flow rate V in real time during the process of water entering the non-porous inner cylinder 1. The inlet flow rate V can be any flow rate, and the water level detection value H is the water level detection value corresponding to any flow rate. For example, the inlet flow rate V can be 5L, 10L, 20L, etc. When the inlet flow rate V is 5L, the water level detection value H is 0.3m; when the inlet flow rate V is 10L, the water level detection value is 0.4m; and when the inlet flow rate V is 20L, the water level detection value is 0.6m.

[0061] The inner drum has an inner drum door at the inner drum opening. When the inner drum is running the water inlet program, washing program, rinsing program, and spin-drying program, the inner drum door is closed and the inner drum is in a closed state. When clothes are put into the inner drum or taken out of the inner drum, the inner drum door is opened.

[0062] For example, when the washing machine is running the water intake program, the inner drum door is closed, and the air pressure inside the inner drum is balanced with the external environment through the overflow structure 5; when water is being introduced, the water inlet pipe sends water from the water source into the water inlet channel 21 and the water inlet passage in sequence, and sprays it into the inner drum from the water outlet of the water inlet passage.

[0063] In an embodiment of the present invention, step S2 further includes:

[0064] After the inlet water level reaches V, the water pressure P inside the non-porous inner cylinder 1 and the external ambient pressure P are measured. 大 gas;

[0065] Based on the water pressure P inside the non-porous inner cylinder 1 and the external environmental pressure P... 大气 The difference is used to obtain the water level detection value H inside the non-porous inner cylinder 1.

[0066] In an embodiment of the present invention, the control unit detects the external environmental pressure value P through a second sensor. 大气 The water pressure P inside the non-porous inner cylinder 1 is compared with the external environmental pressure P. 大气 The difference is converted into a water level detection value H. The water level in the non-porous inner cylinder 1 is judged by combining the water pressure value P in the non-porous inner cylinder 1 with the current external environmental pressure value. In this way, the influence of changes in external environmental air pressure on the water level detection value H can be eliminated, and the problem of different external environmental air pressure affecting the water level detection results can be avoided.

[0067] External environmental pressure value P 大气 The size is affected by factors such as altitude and season. For example, the higher the altitude, the higher the external environmental pressure value P. 大气 The smaller.

[0068] The detection probe of the second sensor is positioned on the outside of the non-porous inner cylinder to contact the external environment and measure the external environmental pressure value P. 大气 ;

[0069] In a preferred embodiment, the first sensor and the second sensor are integrated on the non-porous inner cylinder 1. This can be understood as the first sensor and the second sensor being integrated into one unit to form sensor 4. Sensor 4 has a first detection probe 41 and a second detection probe 42. The first detection probe 41 of sensor 4 is the detection probe of the first sensor, and the second detection probe 42 of sensor 4 is the detection probe of the second sensor. Specifically, sensor 4 is located on the outer wall of the bottom of the non-porous inner cylinder 1. The first detection probe 41 of sensor 4 is inside the non-porous inner cylinder 1, and the second detection probe 42 of sensor 4 is outside the non-porous inner cylinder 1.

[0070] In an embodiment of the present invention, step S3 includes:

[0071] Determine whether the water level detection value H is within the theoretical water level range of 0 to h1 corresponding to the set water inflow V1;

[0072] If not, then the overflow structure 5 is determined to be in an abnormal working state due to blockage.

[0073] In the embodiments of the present invention, the inlet water volume V is any inlet water volume, and the set inlet water volume V1 corresponding to the inlet water volume V refers to the inlet water volume when the inlet water volume V is a set value. Multiple set inlet water volumes V1 serve as multiple discontinuous inlet water volume coordinate points to form the first type of curve mentioned above.

[0074] For example, the influent volume V can be any one of 5L, 10L, or 20L. When the influent volume V is 5L, the corresponding theoretical water level range is 0-0.4m; when the influent volume V is 10L, the corresponding theoretical water level range is 0-0.5m; and when the influent volume V is 20L, the corresponding theoretical water level range is 0-0.7m. The control unit is equipped with 5L, 10L, and 20L water levels, with the theoretical water level range corresponding to 5L being 0-0.4m, 10L being 0-0.5m, and 20L being 0-0.7m.

[0075] The inlet flow rate V can be any one of 5L, 10L, or 20L. Multiple consecutive inlet flow rates of 5L, 10L, or 20L form the second type of curve mentioned above. In this case, an inlet flow rate V of 5L or 10L can be used as a set value. The set inlet flow rate V1 can be any one of 5L or 20L. An inlet flow rate V of 10L is used as a non-set value. When the inlet flow rate V is 5L, the corresponding theoretical water level range is 0-0.4m. When the inlet flow rate V is 20L, the corresponding theoretical water level range is 0-0.7m. The control unit is equipped with 5L and 20L, with a theoretical water level range of 0-0.4m for the inlet flow rate of 5L and 0-0.7m for the inlet flow rate of 20L. Multiple discontinuous inlet flow rates of 5L and 20L form the first type of curve mentioned above.

[0076] This embodiment uses the theoretical water level range 0 to h1 corresponding to the set water inlet volume V1 to compare with the water level detection value H to determine whether the overflow structure 5 is in an abnormal working state due to blockage. This can reduce the number of set water inlet volumes and the number of theoretical water level ranges corresponding to the set water inlet volumes in the control unit.

[0077] For example, when the set water inlet volume V1 is 20L, the obtained water level detection value H is 0.8m. The water level detection value H of 0.8m is not within the theoretical water level range of 0-0.7m corresponding to the set water inlet volume V1 of 20L. At this time, it is determined that the overflow structure 5 is in an abnormal state of blockage.

[0078] The abnormal operating state of the overflow structure 5 is when the overflow structure 5 becomes blocked. For example, when the overflow structure 5 is completely blocked, the non-porous inner cylinder 1 becomes completely closed during the water inlet process. At this time, the water inlet will reduce the gas volume V inside the non-porous inner cylinder 1. According to the isothermal change process, the gas pressure P inside the cylinder will decrease.气 ×Gas volume V = constant, gas pressure P inside the non-porous inner cylinder 1 气 It will increase; based on the water pressure value P inside the cylinder detected by the sensor, the air pressure value P inside the cylinder is equal to the pressure value P. 气 +Water pressure value P inside the cylinder 水 The water pressure P inside the cylinder 水 and external environmental pressure P 大气 If the pressure remains unchanged, the detected water pressure value P inside the cylinder will increase, resulting in a higher water level detection value H inside the non-porous inner cylinder 1 when water is introduced into the inner cylinder to the set water inlet volume V1, which is outside the theoretical water level range of 0 to h1 corresponding to the set water inlet volume V1.

[0079] The table below shows a simplified calculation process, based on an inlet water volume of 1L. It assumes the inner tube 1 (without clothing) has a volume of 60L. When completely blocked, the measured water pressure P inside the inner tube far exceeds the theoretical normal water pressure. Therefore, the degree of blockage in the venting structure can be inferred through abnormal parameter changes.

[0080]

[0081] h1 is the theoretical water level of the non-porous inner cylinder 1 when there is no load and water is introduced to the set water inlet volume V1.

[0082] When there is a load in the non-porous inner cylinder 1, and the load is clothing, the theoretical water level value corresponding to the set water inlet volume V1 is not a single value, but a range of 0 to h1, affected by factors such as the water absorption rate of the clothing and the dryness of the clothing itself.

[0083] Furthermore, before the washing machine executes the water inlet program and introduces water into the non-perforated inner drum 1, it detects that the initial water level of the non-perforated inner drum 1 is h0, which is greater than 0. Therefore, the theoretical water level value range corresponding to the water inlet volume V1 is set to h0~h1.

[0084] In addition, before water is introduced into the non-porous inner cylinder 1, if the initial water level of the non-porous inner cylinder 1 is detected to be h0, and h0 is greater than 0, it indicates that there is residual water in the non-porous inner cylinder. The residual water in the non-porous inner cylinder can be drained before water is introduced into the non-porous inner cylinder. Then the theoretical water level value range corresponding to the water inlet volume V1 is set to 0 to h1.

[0085] Furthermore, if the water level detection value H obtained when the water inlet volume V1 is within the theoretical water level range of 0 to h1, then water continues to be introduced into the non-porous inner drum 1 until the water level in the non-porous inner drum 1 reaches the washing water level. The washing water level is the water level at which the washing program is executed to clean the clothes, and the washing water level is directly proportional to the weight of the load.

[0086] For example, when the set water inlet volume V1 is 20L, the obtained water level detection value H is 0.4m. The water level detection value H is 0.4m, which is within the theoretical water level range of 0-0.7m corresponding to the set water inlet volume V1 of 20L. Water continues to be introduced into the non-porous inner drum 1 until the water level in the non-porous inner drum 1 reaches the washing water level.

[0087] The washing water level mentioned in this application refers to the water level used for normal washing of clothes, which is obtained from the weight of the clothes.

[0088] It should be noted that when initially filling the inner drum with water, the inner drum is rotated for a certain period of time to fully wet the clothes. After the inner drum has rotated for a certain period of time, the rotation is stopped, and water is continued to be filled into the inner drum until the set water volume V1 is reached. By fully wetting the clothes, the accuracy of the water level detection in the inner drum can be guaranteed.

[0089] If the water level detection value H is within the theoretical water level range of 0 to h1 corresponding to the set water inflow V1, it can be considered that the air overflow structure of the non-porous inner cylinder 1 is not blocked. Alternatively, it can be considered that the air overflow structure is blocked and air leakage occurs at other locations of the non-porous inner cylinder.

[0090] In an embodiment of the present invention, after determining that the overflow structure 5 is in an abnormal working state, the control method includes:

[0091] Continue to introduce water into the non-porous inner cylinder 1 to reconfirm whether the overflow structure 5 is in an abnormal working state due to blockage.

[0092] In the embodiments of the present invention, by performing a secondary confirmation on whether the overflow structure 5 is in an abnormal working state of blockage, the accuracy of determining whether the overflow structure 5 is in an abnormal working state of blockage is improved.

[0093] Specifically, the steps for secondary confirmation of whether the overflow structure 5 is blocked include:

[0094] Continue to introduce water into the non-porous inner cylinder 1 until the set water inlet volume V2 is reached, and obtain the water level detection value H of the non-porous inner cylinder 1.

[0095] If the water level detection value H is not within the theoretical water level range of 0 to h2 corresponding to the set water inflow V2, then the overflow structure 5 is confirmed to be in an abnormal working state due to blockage.

[0096] When water is introduced into the non-porous inner cylinder 1 to the set water inlet volume V1, if the water level detection value H is within the theoretical water level range of 0 to h1 corresponding to the set water inlet volume V1, it is considered that the abnormal water level may be caused by a blockage in the overflow structure 5, or by the user introducing water into the non-porous inner cylinder 1 by opening the inner cylinder door. In order to further accurately determine whether the overflow structure 5 is blocked, water is introduced into the inner cylinder to the set water inlet volume V2, and the water level detection value H of the non-porous inner cylinder 1 is obtained again to determine whether the water level detection value H is within the theoretical water level range of 0 to h2 corresponding to the set water inlet volume V2.

[0097] The water inlet volume V2 can be set to any set water inlet volume. For example, the set water inlet volume V2 is greater than the set water inlet volume V1. When the set water inlet volume V1 is 5L, the set water inlet volume V2 is 8L; when the set water inlet volume V1 is 10L, the set water inlet volume V2 is 15L.

[0098] When the inlet flow rate V1 is 5L, the corresponding theoretical water level range is 0-0.4m. When the inlet flow rate V2 is 10L, the corresponding theoretical water level range is 0-0.6m. If the water level detection value H is 0.7m when the inlet flow rate V2 is 10L, and the water level detection value H is 0.7m, which is not within the theoretical water level range of 0-0.6m, then it is confirmed that the overflow structure 5 is in an abnormal working state due to blockage.

[0099] Furthermore, if the water level detection value H obtained when the water inlet volume V2 is within the theoretical water level range of 0 to h2, then water will continue to be introduced into the non-porous inner drum 1 until the water level in the non-porous inner drum 1 reaches the washing water level.

[0100] For example, if the water level detection value H is 0.5m when the water inflow V2 is 10L, and the water level detection value H is 0.5m, which is not within the theoretical water level range of 0-0.6m, then water will continue to be introduced into the non-porous inner cylinder 1 until the water level in the non-porous inner cylinder 1 reaches the set water level.

[0101] Furthermore, after confirming that the overflow structure 5 is in an abnormal working state due to blockage, stop water from entering the non-porous inner cylinder 1 and prompt the user to clean the overflow structure 5.

[0102] As another embodiment of the present invention, after confirming that the overflow structure 5 is in an abnormal working state of blockage, water is stopped from entering the inner cylinder, and the degree of blockage of the overflow structure 5 is determined based on the drop in water level value H within a set time.

[0103] In the embodiments of the present invention, after it is confirmed that the overflow structure 5 is blocked, the water level detection value H drops by different values ​​within a set time, which indicates that the degree of blockage of the overflow structure 5 is different. Thus, different measures can be taken to deal with the blockage of the overflow structure 5 based on the degree of blockage.

[0104] Specifically, if the water level detection value H drops more than the set drop value within a set time, the blockage degree of the overflow structure 5 is the first degree.

[0105] If the water level detection value H drops by the same amount within a set time as the set drop value, then the blockage degree of the overflow structure 5 is greater than the first degree, which is the second degree.

[0106] For example, if the drop in water level is set to 0 and the blockage of the overflow structure 5 is at the first level, it can be considered that the overflow structure 5 is not completely blocked, that is, the inner cylinder is not completely disconnected from the outside atmosphere, and there is ventilation between the two. After the overflow structure 5 is blocked, the drop in water level of the water level detection value H within the set time is greater than 0. The water level detection value H can eventually drop to the theoretical water level value corresponding to the set water inflow.

[0107] When the degree of blockage of the overflow structure 5 is the second degree, it can be considered that the overflow structure 5 is completely blocked, that is, the inner cylinder is disconnected from the outside atmosphere and is not connected at all. It is determined that the water level H after the overflow structure 5 is blocked should drop to 0 within the set time, and the water level does not drop.

[0108] Furthermore, after determining the degree of blockage in the overflow structure 5, the control method includes:

[0109] If the degree of blockage of the overflow structure 5 is the first degree, then water is introduced into the inner drum at the first water inlet speed until the washing water level is reached;

[0110] When the overflow structure 5 is not blocked, water is introduced into the inner cylinder at a water inlet speed greater than the first water inlet speed. The degree of blockage of the overflow structure 5 is the first degree. If the blockage of the overflow structure 5 is not serious, water can be introduced into the inner cylinder at the first water inlet speed to slow down the water inlet speed and prevent the pipe from bursting.

[0111] If the degree of blockage of the overflow structure 5 is greater than the first degree, the water supply to the inner drum will continue to stop, prompting the user to clean the overflow structure 5, or to supply water to the inner drum at a second water supply rate less than the first water supply rate until the washing water level is reached.

[0112] The degree of blockage of the overflow structure 5 is the second level. The blockage of the overflow structure 5 is relatively serious. Water can be introduced into the inner cylinder at a second water inlet speed that is less than the first water inlet speed to further slow down the water inlet speed. When the overflow structure 5 is completely blocked, water inlet into the inner cylinder will be stopped, prompting the user to clean the overflow structure 5.

[0113] The washing machine has an inlet valve on its water inlet pipe. By adjusting the opening of the inlet valve, the water inlet speed can be changed.

[0114] like Figure 2 As shown, in a specific embodiment of the present invention, the control method of the washing machine includes:

[0117] S3. Determine whether the water level detection value H is within the theoretical water level range of 0 to h1. If not, proceed to step S4; if yes, proceed to step S9.

[0118] S4. Continue to feed water into the non-porous inner cylinder 1 until the set water volume V2 is reached, and then proceed to step S5.

[0119] S5. Obtain the water level detection value H of the non-porous inner cylinder 1, and proceed to step S6.

[0120] S6. Determine whether the water level detection value H is within the theoretical water level range of 0 to h2. If not, proceed to step S7; if yes, proceed to step S9.

[0121] S7. Determine that the overflow structure 5 is in an abnormal working state due to blockage, and proceed to step S8.

[0122] S8. Stop water from entering the non-porous inner cylinder 1 and prompt the user to clean the overflow structure 5;

[0123] S9. Continue to add water to the inner drum until the water level in the inner drum reaches the washing water level.
