Description

Technical Field

[0001] This invention relates to the field of smart home technology, and specifically provides a control method for washing equipment. Background Technology

[0002] Washing machines are common household laundry appliances. Based on their washing methods, washing machines can be broadly classified into top-loading (pulsator) washing machines and front-loading (drum) washing machines. Taking a top-loading washing machine as an example, during operation, the user puts the clothes into the inner drum, adds washing water matching the weight of the clothes, and then starts the default washing program. No program settings are available; the washing parameters are fixed.

[0003] However, since different materials of clothing have different properties, they also require different washing parameters. If the same washing parameters (such as washing time, washing water flow, etc.) are used in the washing program, it is often not suitable and may not be able to wash the clothes clean, thus affecting the user experience.

[0004] Therefore, there is a need in the art for a new control method for washing equipment to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems in the prior art, namely, the inability of existing washing equipment to effectively clean clothes due to fixed washing parameters, this invention provides a control method for a washing equipment. This control method includes the following steps: acquiring the washing water level of the washing equipment; acquiring the theoretical water intake of the washing equipment; determining whether the washing water level is less than or equal to a set water level; determining a water injection method based on the determination result; after the washing equipment injects water to the washing water level according to the determined water injection method, calculating the actual water injection volume of the washing equipment; and selectively adjusting the washing parameters of the washing equipment based on the actual water injection volume and the theoretical water intake volume.

[0006] In the preferred embodiment of the above control method, the step of "determining the water injection method based on the judgment result of whether the washing water level is less than or equal to the set water level" specifically includes: if the washing water level is less than or equal to the set water level, then determining whether the washing water level is greater than the minimum water level of the washing equipment; based on the judgment result of whether the washing water level is greater than the minimum water level, selectively allowing the washing equipment to directly or indirectly inject water to the washing water level.

[0007] In the preferred embodiment of the above control method, the step of "selectively filling the washing equipment directly or indirectly with water to the washing water level according to the judgment result of whether the washing water level is greater than the minimum water level" specifically includes: if the washing water level is less than or equal to the minimum water level, then filling the washing equipment directly with water to the washing water level.

[0008] In the preferred embodiment of the above control method, the step of "selectively injecting water directly or indirectly to the washing equipment according to the judgment result of whether the washing water level is greater than the minimum water level" further includes: if the washing water level is greater than the minimum water level, then the washing equipment is indirectly injected to the washing water level.

[0009] In the preferred embodiment of the above control method, the step of "indirectly filling the washing device with water to the washing water level" specifically includes: filling the washing device with water to a first preset water level, wherein the first preset water level is lower than the washing water level; after the washing device is filled with water to the first preset water level, performing an auxiliary water suction operation; and after the washing device performs the auxiliary water suction operation, continuing to fill the washing device with water to the washing water level.

[0010] In the preferred embodiment of the above control method, the step of "determining the water injection method based on the judgment result of whether the washing water level is less than or equal to the set water level" further includes: if the washing water level is greater than the set water level, then the washing equipment is indirectly injected with water to the washing water level.

[0011] In the preferred embodiment of the above control method, the step of "indirectly filling the washing device with water to the washing water level" specifically includes: filling the washing device with water to a second preset water level; after the washing device is filled with water to the second preset water level, performing an auxiliary water suction operation; after the washing device performs the auxiliary water suction operation, continuing to fill the washing device with water to a third preset water level; after the washing device is filled with water to the third preset water level, performing the auxiliary water suction operation again; after the washing device performs the auxiliary water suction operation again, continuing to fill the washing device with water to the washing water level; wherein, the second preset water level is lower than the third preset water level, and the third preset water level is lower than the washing water level.

[0012] In the preferred embodiment of the above control method, the step of "causing the washing equipment to perform auxiliary water absorption operation" specifically includes: causing the washing equipment to execute a washing program according to preset parameters of the agitated water flow; wherein, the parameters of the agitated water flow include at least one of the rotation-stop ratio, rotation speed, and balancing time.

[0013] In the preferred embodiment of the above control method, the step of "selectively adjusting the washing parameters of the washing equipment according to the actual water injection volume and the theoretical water intake volume" specifically includes: calculating the ratio of the actual water intake volume to the theoretical water intake volume; comparing the ratio with a preset value; and selectively adjusting the washing parameters of the washing equipment according to the comparison result of the ratio and the preset value; wherein the washing parameters include washing time and / or water flow intensity.

[0014] In the preferred embodiment of the above control method, the step of "selectively adjusting the washing parameters of the washing device according to the comparison result of the ratio and the preset value" specifically includes: if the ratio is less than the preset value, then extending the washing time and increasing the water flow intensity; and / or if the ratio is greater than the preset value, then shortening the washing time and reducing the water flow intensity; and / or if the ratio is equal to the preset value, then not adjusting the washing parameters.

[0015] In a preferred embodiment of the control method of the present invention, the washing water level of the washing machine is obtained; the theoretical water intake of the washing machine is obtained; it is determined whether the washing water level is less than or equal to the set water level; the water injection method is determined based on the determination result of whether the washing water level is less than or equal to the set water level; after the washing machine is filled with water to the washing water level, the actual water injection volume of the washing machine is counted; and the washing parameters of the washing machine are selectively adjusted based on the actual water injection volume and the theoretical water intake volume.

[0016] Compared to existing technologies with fixed washing parameters, the washing machine of this invention, during operation, firstly, selects a suitable water injection method based on whether the washing water level is lower than the set water level. This ensures that the actual water intake of the washing machine reaches the washing water level, preventing the actual water level from falling below the washing water level due to clothes absorbing water, thus improving the accuracy of water injection. Secondly, based on the actual water injection volume and the theoretical water intake volume, the washing parameters of the washing machine are selectively adjusted to match the washing parameters with the water absorption performance of the clothes, providing reasonable washing and care for the clothes, cleaning them thoroughly, and thus improving the user experience.

[0017] Furthermore, if the washing water level is less than or equal to the set water level, it indicates that the washing water level is low, possibly the minimum water level. Correspondingly, the amount of laundry is also very small, and even if the laundry absorbs water, it will not cause the water level to drop significantly. The washing water level may also be higher than the minimum water level but still low. In order to accurately determine the water filling method of the washing machine, it is determined whether the washing water level is greater than the minimum water level of the washing machine. Based on the determination result, the washing machine is selectively made to fill water directly or indirectly to the washing water level. This avoids indirect water filling when the washing water level is at the minimum water level, avoids prolonging the water filling time, and determines the most reasonable water filling method for the washing machine, further improving the user experience.

[0018] Furthermore, if the washing water level is higher than the set water level, it indicates that the washing water level is high and the number of clothes is correspondingly large. If water is directly added to the washing water level, too many clothes will not have enough time to absorb water. During the washing process, the clothes will gradually absorb water, causing the water level to drop, resulting in the actual water level being lower than the washing water level. To avoid the above situation, the washing machine is indirectly added to the washing water level. This allows the clothes to fully absorb water during the water filling process. Once the washing machine is filled with water to the washing water level, the water level will not drop due to the clothes absorbing water, and it can be stably maintained at the washing water level, which can meet the washing needs of the clothes, provide reasonable washing and care for the clothes, and clean the clothes, further improving the user experience.

[0019] Furthermore, the ratio of the actual water intake to the theoretical water intake of the washing machine is calculated, and this ratio is compared with a preset value. Based on the comparison result, the water absorption performance of the clothes can be accurately determined, and the washing parameters of the washing machine can be selectively adjusted according to the water absorption performance of the clothes. This ensures that the actual washing parameters of the washing machine match the water absorption performance of the clothes, providing the most reasonable washing and care for the clothes, cleaning them thoroughly, and thus improving the user experience.

[0028] Figure 8 This is a logic diagram of the control method of the present invention. Detailed Implementation

[0029] 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. For example, although the present invention is described in connection with a washing machine, the technical solution of the present invention is not limited thereto, and this control method can obviously also be applied to other washing equipment such as washer-dryer combos.

[0030] Based on the technical problems mentioned in the background art, the present invention provides a control method for a washing machine. The method aims to select a suitable water injection method based on the judgment result of whether the washing water level is lower than the set water level, thereby ensuring that the actual water intake of the washing machine can ensure that the actual water level reaches the washing water level, avoiding the actual water level falling below the washing water level due to water absorption by clothes, and improving the accuracy of water injection. Furthermore, based on the actual water injection volume and the theoretical water intake volume, the washing parameters of the washing machine are selectively adjusted so that the washing parameters match the water absorption performance of the clothes, providing reasonable washing and care for the clothes, cleaning them thoroughly, and thus improving the user experience.

[0031] First see Figure 1 The control method of the present invention will be described below. Figure 1 This is the main flowchart of the control method of the present invention.

[0032] like Figure 1 As shown, the control method of the present invention includes the following steps:

[0033] S100: Obtain the washing water level of the washing machine;

[0034] S200, Obtain the theoretical water intake capacity of the washing machine;

[0035] S300: Determine whether the washing water level is less than or equal to the set water level;

[0036] S400: Determine the water injection method based on the judgment result of whether the washing water level is less than or equal to the set water level;

[0037] S500: After the washing machine fills water to the washing water level according to the determined water filling method, the actual water filling amount of the washing machine is counted.

[0038] S600: Selectively adjusts the washing parameters of the washing machine based on the actual water volume and the theoretical water volume.

[0039] The theoretical water intake is the water intake corresponding to the washing water level. That is, under the premise that the weight of the clothes matches the washing water level and the clothes have moderate water absorption, such as clothes with moderate water absorption and easy to clean, like synthetic fibers, cotton and linen, the theoretical water intake of the washing machine to the washing water level.

[0040] In steps S100 and S200, the washing water level and theoretical water intake of the washing machine can be obtained after the washing machine is started but before the water filling operation is performed. Specifically, the washing water level and theoretical water intake can be obtained by: obtaining the weight of the clothes and determining the washing water level and theoretical water intake based on the weight of the clothes; or obtaining the quantity of clothes and determining the washing water level and theoretical water intake based on the quantity of clothes; or obtaining the washing program selected by the user or the washing program recommended by the washing machine and determining the washing water level and theoretical water intake based on the washing program. Regardless of the method used, as long as the washing water level and theoretical water intake can be obtained, it is acceptable. This invention does not impose any limitations on this.

[0041] It should be noted that the execution order of steps S100 and S200 in the above process is not limited to the order listed above. Step S200 can be executed first, followed by step S100, or steps S100 and S200 can be executed simultaneously. Those skilled in the art can flexibly adjust and set the execution order of steps S100 and S200 according to actual usage requirements.

[0042] The following reference Figures 2 to 5 The control method for determining the water injection mode of the present invention is described herein. Wherein, Figure 2 This is a flowchart of the control method for determining the water injection mode based on the judgment result of whether the washing water level is less than or equal to the set water level according to the present invention; Figure 3 This is a flowchart of the control method of the present invention, which selectively controls the washing machine to directly or indirectly inject water to the washing water level based on the judgment result of whether the washing water level is greater than the minimum water level. Figure 4This is a flowchart of the control method of the present invention, which causes the washing machine to indirectly inject water to the washing water level when the washing water level is greater than the minimum water level. Figure 5 This is a flowchart of a control method for indirectly injecting water into the washing machine to reach the washing water level when the washing water level is higher than the set water level.

[0043] like Figure 2 As shown, step S400, the step of "determining the water injection method based on the judgment result of whether the washing water level is less than or equal to the set water level" specifically includes:

[0044] S411. If the washing water level is less than or equal to the set water level, determine whether the washing water level is greater than the minimum water level of the washing machine.

[0045] S412. Based on the judgment result of whether the washing water level is greater than the minimum water level, selectively make the washing machine directly or indirectly fill water to the washing water level.

[0046] S413. If the washing water level is higher than the set water level, the washing machine will indirectly fill water to the washing water level.

[0047] The set water level is higher than the washing machine's minimum water level but lower than its maximum water level. Preferably, the set water level is the middle water level of the washing machine. For example, if the washing machine has ten water levels, the set water level is the fifth level. Of course, the set water level can also be the fourth level, the sixth level, or other water levels. Those skilled in the art can flexibly adjust and set the set water level, as long as it is between the minimum and maximum water levels.

[0048] It should be noted that in the above process, steps S411 and S413 are not sequential but parallel, and are only related to the judgment result of whether the washing water level is less than or equal to the set water level. The corresponding steps can be executed according to different judgment results.

[0049] like Figure 3 As shown, step S412, "selectively filling the washing machine directly or indirectly with water to the washing water level based on the judgment result of whether the washing water level is greater than the minimum water level," specifically includes:

[0050] S421. If the washing water level is less than or equal to the minimum water level, the washing machine will directly fill water to the washing water level.

[0051] S422. If the washing water level is higher than the minimum water level, the washing machine will indirectly fill water to the washing water level.

[0052] In step S421, if the washing water level is less than or equal to the minimum water level, for example, if the water level is set to level 5 and the minimum water level is level 1, and the washing water level is level 1, which is equal to the minimum water level, the washing water level is the lowest, and the corresponding number of clothes is also very small, for example, one or two pieces of clothing. Even if the clothes absorb water, the water level will not drop significantly, and there is no need to add water in batches. In this case, the washing machine will directly add water to level 1.

[0053] In step S422, if the washing water level is higher than the minimum water level (for example, the set water level is level 5, the minimum water level is level 1, and the washing water level is level 4), the washing water level is higher than the minimum water level but lower than the set water level. The washing water level is lower, and correspondingly, the number of clothes is also smaller, such as four or five pieces of clothing. However, the clothes will absorb water, causing the water level to drop, making the actual water level significantly lower than the washing water level. To avoid the above situation, the washing machine is indirectly filled with water to the washing water level. The specific water filling method is as follows.

[0054] like Figure 4 As shown, step S422, the step of "indirectly filling the washing machine with water to the washing water level" specifically includes:

[0055] S431. Fill the washing machine with water to the first preset water level;

[0056] S432. After the washing machine is filled with water to the first preset water level, the washing machine performs an auxiliary water suction operation.

[0057] S433. After the washing machine performs the auxiliary water suction operation, allow the washing machine to continue filling water to the washing water level;

[0058] Wherein, the first preset water level is lower than the washing water level. Preferably, the first preset water level can change with the change of the washing water level. For example, the first preset water level is one or two levels higher than the washing water level. If the washing water level is four levels, then the first preset water level is three levels or two levels. Or the first preset water level is a set value, such as level one, which ensures that when the washing water level is between level two and the set water level, the water can be indirectly injected to the washing water level.

[0059] In steps S431 to S433, for example, the water level is set to level 5, the washing water level is set to level 4, and the first preset water level is level 1. During the water filling process, the washing machine is first filled to level 1. After the washing machine is filled to level 1, the washing machine performs an auxiliary water suction operation to allow the clothes to fully absorb water, thereby accurately affecting the washing water level. When the washing machine is filled to the washing water level, the water level will not drop due to the clothes absorbing water and can be stably maintained at the washing water level. Then, after the washing machine performs the auxiliary water suction operation, the washing machine continues to fill water to level 4.

[0060] The washing machine includes a pulsator; the step of "making the washing machine perform auxiliary water suction operation" specifically includes: making the washing machine perform a washing program according to preset parameters of the agitated water flow.

[0061] The parameters of the agitated water flow include the rotation-to-stop ratio, rotational speed, and balancing time. Of course, the parameters of the agitated water flow may only include the rotation-to-stop ratio, rotational speed, or balancing time, or any two of the rotation-to-stop ratio, rotational speed, and balancing time. Those skilled in the art can flexibly adjust and set the parameters of the agitated water flow.

[0062] For example, the washing machine can be set to a rotation-stop ratio of 0.4 / 0.5 and a spin speed of 90 rpm, with the impeller rotating continuously in both forward and reverse directions for 2 minutes. This ensures that the clothes and washing water come into full contact, allowing the clothes to absorb water evenly and thoroughly.

[0063] It should be noted that the washing water level, maximum water level, set water level, first preset water level, spin-stop ratio, spin speed and balancing time listed above are merely illustrative and not restrictive. Those skilled in the art can flexibly adjust the washing water level, maximum water level, set water level, first preset water level, spin-stop ratio, spin speed and balancing time according to actual usage needs and washing machine model in practical applications.

[0064] It should also be noted that in the above process, steps S421 and S422 are not sequential but parallel, and are only related to the judgment result of whether the washing water level is greater than the minimum water level of the washing machine. The corresponding steps can be executed according to different judgment results.

[0065] like Figure 5 As shown, in step S413, when the washing water level is higher than the set water level, the step of "indirectly filling the washing machine with water to the washing water level" specifically includes:

[0066] S441. Fill the washing machine with water to the second preset water level;

[0067] S442. After the washing machine is filled with water to the second preset water level, the washing machine performs an auxiliary water suction operation.

[0068] S443. After the washing machine performs the auxiliary water suction operation, allow the washing machine to continue filling water to the third preset water level;

[0069] S444. After the washing machine is filled with water to the third preset water level, the washing machine performs the auxiliary water suction operation again.

[0070] S445. After the washing machine performs the auxiliary water suction operation again, allow the washing machine to continue filling water to the washing water level.

[0071] The second preset water level is lower than the third preset water level, and the third preset water level is lower than the washing water level. Preferably, the second preset water level is a level 2 water level, and the third preset water level is one level lower than the washing water level, that is, the third preset water level changes with the change of the washing water level.

[0072] In steps S441 to S445, for example, the water level is set to level 5, the washing water level is set to level 8, the second preset water level is set to level 2, and the third preset water level is set to level 7. During the water filling process, the washing machine is first filled to level 2. After the washing machine is filled to level 2, the washing machine performs the first auxiliary water suction operation to allow the clothes to fully absorb water. However, due to the large number of clothes, even after the first auxiliary water suction operation, the clothes may not have absorbed enough water. To ensure that the clothes can absorb enough water, after the washing machine performs the first auxiliary water suction operation, the washing machine continues to fill to level 7. After the washing machine is filled to level 7, the washing machine performs the auxiliary water suction operation again to allow the clothes to fully and completely absorb water, thereby accurately affecting the washing water level. When the washing machine is filled to the washing water level, the water level will not drop due to the clothes absorbing water and can be stably maintained at the washing water level. Only after the washing machine performs the auxiliary water suction operation again will the washing machine continue to fill to level 8.

[0073] The following section uses parameters of the agitated water flow, including the rotation-to-stop ratio, rotation speed, and equilibrium time, as examples to further illustrate the specific steps of the two auxiliary water suction operations.

[0074] In step S442, the step of "making the washing machine perform the auxiliary water suction operation for the first time" specifically includes: making the washing machine perform the washing program according to the preset parameters of the agitated water flow.

[0075] For example, the washing machine can be set to a rotation-stop ratio of 0.45 / 0.5 and a spin speed of 95 rpm, with the impeller rotating continuously in both forward and reverse directions for 1.5 minutes. This allows the clothes to come into full contact with the washing water, enabling the clothes to absorb water evenly and thoroughly.

[0076] In step S444, the step of "making the washing machine perform the auxiliary water suction operation again" specifically includes: making the washing machine perform the washing program according to the preset parameters of the agitated water flow.

[0077] For example, the washing machine can be set to a rotation-stop ratio of 0.4 / 0.45 and a spin speed of 98 rpm, with the impeller rotating continuously in both forward and reverse directions for 2.5 minutes. This allows the clothes to come into full contact with the washing water, enabling the clothes to absorb water evenly and thoroughly.

[0078] It should be noted that although the parameters of the agitated water flow for "making the washing machine perform the auxiliary water suction operation for the first time", the parameters of the agitated water flow for "making the washing machine perform the auxiliary water suction operation again" and the parameters of the agitated water flow for "making the washing machine perform the auxiliary water suction operation" in step S432 are different from each other, this is only illustrative and not restrictive. The parameters of the agitated water flow for the above three auxiliary water suction operations can also be set to be the same, or any two of the parameters of the agitated water flow can be the same. Those skilled in the art can flexibly adjust and set the parameters of the agitated water flow for the above three auxiliary water suction operations.

[0079] It should be noted that the set water level, washing water level, second preset water level, third preset water level, spin-stop ratio, speed and balancing time listed above are merely illustrative and not restrictive. Those skilled in the art can flexibly adjust the set water level, washing water level, second preset water level, third preset water level, spin-stop ratio, speed and balancing time according to actual usage needs and washing machine model in practical applications.

[0080] The following reference Figure 6 and Figure 7 The method for selectively adjusting washing parameters according to the present invention will be described. Figure 6 This is a flowchart of the control method of the present invention, which selectively adjusts the washing parameters of a washing machine based on the actual water volume and the theoretical water volume. Figure 7 This is a flowchart of the control method of the present invention, which selectively adjusts the washing parameters of a washing machine based on the judgment result of whether the ratio is greater than a preset value.

[0081] like Figure 6 As shown, step S600, "selectively adjusting the washing parameters of the washing machine according to the actual water volume and the theoretical water volume," specifically includes:

[0082] S611. Calculate the ratio of actual inflow to theoretical inflow.

[0083] S612. Compare the ratio with the preset value;

[0084] S613. Based on the comparison result between the ratio and the preset value, selectively adjust the washing parameters of the washing machine;

[0085] The washing parameters include washing time and water flow intensity. Of course, the washing parameters may also include only washing time or water flow intensity, and those skilled in the art can flexibly adjust and set the washing parameters.

[0086] In step S611, taking the washing water level as an example, the theoretical water intake V0 is 20L, the actual water intake V1 is 19.8L, and the actual water intake V1 / theoretical water intake V0 = 19.8 / 20 = 0.99.

[0087] Alternatively, taking a washing machine with eight water levels as an example, the theoretical water intake V0 is 40L, and the actual water intake V1 is 41L. The actual water intake V1 / theoretical water intake V0 = 41 / 40 = 1.025.

[0088] Alternatively, taking a washing water level of eight as an example, the theoretical water intake V0 is 40L, the actual water intake V1 is 40L, and the actual water intake V1 / theoretical water intake V0 = 40 / 40 = 1.

[0089] like Figure 7 As shown, step S613, "selectively adjusting the washing parameters of the washing machine based on the comparison result between the ratio and the preset value," specifically includes:

[0090] S621. If the ratio is less than the preset value, extend the washing time and increase the water flow intensity.

[0091] S622. If the ratio is greater than the preset value, shorten the washing time and reduce the water flow intensity.

[0092] S623. If the ratio is equal to the preset value, then the washing parameters are not adjusted.

[0093] In step S621, if the ratio is less than the preset value, for example, the preset value is 1, and the ratio calculated in step S611 is 0.99, which is less than the preset value, it indicates that the clothes have poor water absorption. The clothes are denim jackets, jeans, windbreakers, etc., which are not easy to clean. In order to clean the clothes, the washing time is extended and the water flow intensity is increased. For example, if the program recommends a washing time of 30 minutes, a spin speed of 90 rpm, and a spin-stop ratio of 0.4 / 0.5, then the washing time is extended to 35 minutes, the spin speed is increased to 95 rpm, and the spin-stop ratio is increased to 0.5 / 0.5.

[0094] In step S622, if the ratio is greater than the preset value, for example, the preset value is 1, and the ratio calculated in step S611 is 1.025, which is greater than the preset value, it indicates that the clothes have good water absorption and that the clothes are wool, cashmere, or other clothes that are very easy to clean. In order to avoid damage to the clothes, the washing time is shortened and the water flow intensity is reduced. For example, if the program recommends a washing time of 40 minutes, a spin speed of 98 rpm, and a spin-stop ratio of 0.4 / 0.45, then the washing time is shortened to 33 minutes, the spin speed is reduced to 93 rpm, and the spin-stop ratio is reduced to 0.4 / 0.5.

[0095] In step S623, if the ratio is equal to the preset value, for example, the preset value is 1, and the ratio calculated in step S611 is 1, which is equal to the preset value, it means that the absorbency of the clothes is moderate, the clothes are easy to clean such as chemical fiber, cotton and linen, and match the washing parameters recommended by the program, then the washing parameters are not adjusted. For example, if the program recommends a washing time of 40 minutes, a spin speed of 98 rpm, and a spin-stop ratio of 0.4 / 0.45, these parameters are maintained.

[0096] It should be noted that the washing water level, theoretical water intake, actual water intake, ratio, preset value, spin-stop ratio, speed and balancing time listed above are merely illustrative and not restrictive. Those skilled in the art can flexibly adjust the washing water level, theoretical water intake, actual water intake, ratio, preset value, spin-stop ratio, speed and balancing time according to actual usage needs and washing machine model in practical applications.

[0097] It should also be noted that in the above process, steps S621 to S623 are not sequential but parallel, and are only related to the comparison result between the ratio and the preset value. The corresponding steps can be executed according to different judgment results.
