Description

Technical Field

[0001] The present invention relates to the technical field of washing equipment, and specifically provides a control method for washing equipment and washing equipment. Background Art

[0002] With the improvement of people's quality of life and the acceleration of work pace, cleaning work is gradually replaced by washing equipment. People are also more inclined to use easily soluble and efficient detergents.

[0003] However, due to different family education backgrounds and usage habits, users have different requirements for appearance indicators (such as the amount of foam) during the washing process. Some older people like washing methods with rich foam, while young people, who are generally more educated, prefer washing methods with less foam.

[0004] At present, the existing washing equipment does not have the foam adjustment function, and it is impossible to adjust the foam amount when used with detergents that can adjust the foam amount. For those who prefer rich foam, adding more detergent can achieve a rich foam washing effect, but it will cause a waste of detergent. For those who prefer less foam washing, reducing the amount of detergent can achieve a less foam washing effect, but it will affect the cleaning power, resulting in a poor user experience. Summary of the invention

[0005] The present invention aims to solve the above technical problem at least to a certain extent, that is, to solve at least to a certain extent the problem that the existing washing equipment cannot adjust the amount of washing foam, resulting in poor user experience.

[0006] In a first aspect, the present invention provides a control method for a washing device, which has a washing drum. After a washing solution is injected into the washing drum, the control method comprises the following steps: obtaining an actual pH value of the washing solution; obtaining a preset foam parameter set by a user; and selectively adjusting the pH value of the washing solution according to the actual pH value and the preset foam parameter; wherein the washing solution is a solution system containing a detergent, and the detergent can adjust the amount of foam generated during the washing process according to the pH value of the washing solution.

[0007] In the preferred technical scheme of the control method for washing equipment mentioned above, the preset foam parameter is a preset foam amount level, and the step of "obtaining the preset foam parameter set by the user" specifically includes: obtaining the preset foam amount level set by the user; the step of "selectively adjusting the pH value of the washing solution according to the actual pH value and the preset foam parameter" specifically includes: obtaining a preset pH value range corresponding to the preset foam amount level; selectively adjusting the pH value of the washing solution according to the actual pH value and the preset pH value range.

[0008] In the preferred technical solution of the control method for washing equipment mentioned above, the step of "selectively adjusting the pH value of the washing solution according to the actual pH value and the preset pH value range" specifically includes: judging whether the actual pH value is within the preset pH value range; and selectively adjusting the pH value of the washing solution according to the judgment result.

[0009] In the preferred technical solution of the control method for washing equipment, the step of "selectively adjusting the pH value of the washing solution according to the judgment result" specifically includes: if the judgment result is "no", adjusting the pH value of the washing solution.

[0010] In the preferred technical solution of the control method for washing equipment, the step of "adjusting the pH value of the washing solution" specifically includes: comparing the actual pH value with the pH value of the washing solution. max and PH min According to the comparison result, the pH value of the washing solution is selectively increased or decreased; wherein, the pH max The maximum pH value within the preset pH range. min It is the minimum pH value within the preset pH range.

[0011] In the preferred technical solution of the control method for the washing device, the step of "selectively increasing or decreasing the pH value of the washing solution according to the comparison result" specifically includes: if the actual pH value is greater than the pH value max , then lower the pH value of the washing solution; and / or, if the actual pH value is less than pH min , then the pH value of the washing solution is adjusted higher.

[0012] In the preferred technical solution of the control method for washing equipment mentioned above, during the process of adjusting the pH value of the washing solution, the control method also includes: acquiring the current pH value of the washing solution in real time; judging whether the current pH value reaches the preset pH value range; and selectively ending the pH value adjustment of the washing solution according to the judgment result.

[0013] In the preferred technical solution of the control method for washing equipment mentioned above, the step of "selectively ending the pH adjustment of the washing solution according to the judgment result" specifically includes: if the judgment result is "yes", ending the pH adjustment of the washing solution; and / or, if the judgment result is "no", not ending the pH adjustment of the washing solution.

[0014] In the preferred technical solution of the control method for washing equipment, the step of "selectively adjusting the pH value of the washing solution according to the judgment result" specifically includes: if the judgment result is "yes", the pH value of the washing solution is not adjusted.

[0015] In a second aspect, the present invention provides a washing device, the washing device comprising a controller, wherein the controller is configured to execute the control method introduced above.

[0016] When adopting the above-mentioned preferred technical scheme, the present application can selectively adjust the pH value of the washing solution according to the actual pH value of the washing solution and the preset foam amount or preset foam level set by the user, thereby being able to adjust the amount of foam that can be generated by the washing solution by adjusting the pH value of the washing solution, and then being able to make the amount of foam generated by the washing solution during the washing process consistent with the amount of foam preset by the user, thereby meeting the washing needs of users with different washing preferences and greatly improving the user experience.

[0017] Furthermore, compared with first obtaining a preset pH value corresponding to a preset foam amount, and then selectively adjusting the pH of the washing solution according to the actual pH value and the preset pH value, by first obtaining a preset pH value range corresponding to a preset foam amount level, and then selectively adjusting the pH of the washing solution according to the actual pH value and the preset pH value range, on the one hand, it can avoid misjudgment caused by detection errors of the pH detection sensor, and on the other hand, it can also reduce the pH adjustment of the washing solution as much as possible on the basis of satisfying the user's preference for the amount of washing foam, thereby further improving the user's experience.

[0018] Furthermore, compared with the method of first calculating the difference between the actual pH value and the threshold of the preset pH value range, and then comparing the difference with the preset value, and selectively adjusting the pH value of the washing solution according to the comparison result, the method of directly judging whether the actual pH value is within the preset pH value range and selectively adjusting the pH value of the washing solution according to the judgment result can more accurately and intuitively judge whether the actual pH value of the washing solution is in line with the preset pH value range corresponding to the preset foam parameters selected by the user, thereby more accurately making the amount of foam generated by the washing solution during the washing process meet the user's washing needs, further improving the user's usage experience.

[0019] Furthermore, when the judgment result is "no", it means that the actual pH value is not within the preset pH value range. If the pH value of the washing solution is not adjusted, the amount of foam generated during the actual washing process will be greatly different from the preset foam amount set by the user. At this time, timely adjusting the pH value of the washing solution can make the actual pH value closer to the preset pH value range, thereby making the amount of foam generated during the actual washing process closer to the preset foam amount set by the user, thereby improving the user experience.

[0020] Furthermore, by comparing the actual pH value with the pH max and PH min By making a comparison and selectively adjusting the pH value of the washing solution higher or lower according to the comparison result, it is possible to accurately determine whether the actual pH value is lower or higher than the preset pH value range, and then accurately adjust the pH value of the washing solution according to the comparison result to improve the adjustment efficiency.

[0021] Furthermore, when the actual pH value is greater than pH max In the case of , it means that the actual pH value is higher than the preset pH value range. At this time, lowering the pH value of the washing solution can make the actual pH value within the preset pH value range. min In the case of, it means that compared with the preset pH value range, the actual pH value is lower. At this time, increasing the pH value of the washing solution can make the actual pH value within the preset pH value range, thereby making the amount of foam generated in the actual washing process match the preset foam amount level selected by the user, thereby meeting the user's washing needs.

[0022] Furthermore, in the process of adjusting the pH value of the washing solution, by obtaining the current pH value of the washing solution in real time, it is determined whether the current pH value reaches the preset pH value range, and the pH value adjustment of the washing solution is selectively terminated according to the judgment result. The pH value of the washing solution can be gradually adjusted, so that the pH of the washing solution can be adjusted more quickly and accurately, thereby improving the adjustment efficiency and adjustment accuracy of the pH value adjustment, and further enhancing the user experience.

[0023] Furthermore, when the judgment result is "yes", it means that the current pH value has reached the preset pH value range, that is, the amount of foam generated during the washing process is consistent with the preset foam amount level set by the user. At this time, the pH adjustment of the washing solution is ended, which can improve the adjustment efficiency of the pH value and further enhance the user experience.

[0024] In addition, the washing device further provided by the present invention on the basis of the above-mentioned technical scheme includes the control method for washing devices introduced above, and thus has the beneficial effects of the control method for washing devices mentioned above. Compared with the washing device before the improvement, the foam of the washing device of the present invention is easier to adjust and can better meet the needs of users with different washing preferences. At the same time, it is not easy to waste detergent due to preference for rich foam, nor is it easy to affect the cleaning power due to preference for less foam washing, and the user experience is better.

[0034] See also Figure 1 , Figure 1 It is a flow chart of the control method for washing equipment of the present invention.

[0035] like Figure 1 As shown, the washing device of the present invention has a washing drum. After the washing solution is injected into the washing drum, the control method of the present invention comprises the following steps:

[0036] S1: Obtain the actual pH value of the washing solution;

[0037] S2: Obtaining preset foam parameters set by the user;

[0038] S3: selectively adjusting the pH value of the washing solution according to the actual pH value and the preset foam parameters;

[0039] Among them, the preset foam parameters include a preset foam amount or a preset foam amount level, and the washing solution is a solution system containing a detergent, and the detergent can adjust the amount of foam generated during the washing process according to the pH value of the washing solution.

[0040] Through such a setting, the pH value of the washing solution can be selectively adjusted according to the actual pH value of the washing solution and the preset foam amount or preset foam level set by the user, so that the amount of foam that can be generated by the washing solution can be adjusted by adjusting the pH value of the washing solution, and then during the washing process, the amount of foam generated by the washing solution can be consistent with the amount of foam preset by the user, thereby meeting the washing needs of users with different washing preferences and greatly improving the user experience.

[0041] It should be noted that, in actual applications, those skilled in the art may directly inject a mixed solution of detergent and water into the washing drum as a washing solution, or may first inject water into the washing drum, then inject detergent into the washing drum, and the detergent and water are mixed to form a washing solution, or may first inject detergent into the washing drum, then inject water into the washing drum, and the detergent and water are mixed to form a washing solution, and so on. Such adjustments and changes to the specific injection method of the washing solution do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0042] Preferably, detergent is first injected into the washing tub, and then water is injected into the washing tub, and the detergent and water are mixed to form a washing solution.

[0043] It should be noted that, in actual applications, those skilled in the art may take out part of the washing solution in the washing drum and detect the pH value of the washing solution to obtain the actual pH value, or may set a pH detection sensor in the washing drum to detect the pH value of the washing solution in the washing drum by the pH detection sensor to obtain the actual pH value, or may obtain the actual pH value of the washing solution by any other possible form, etc. Such adjustments and changes to the specific method of obtaining the actual pH value of the washing solution do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0044] Preferably, the washing device of the present invention further comprises a pH detection sensor (not shown in the figure), and the pH value of the washing solution in the washing tub is detected by the pH detection sensor.

[0045] Through such a setting, the pH value of the washing solution in the washing drum can be detected more conveniently, the intelligent detection of the washing solution can be realized, and the user experience is further improved.

[0046] It should be noted that, in actual applications, technicians in this field can obtain the preset foam parameters set by the user by having the user operate the buttons on the washing device, or can also obtain the preset foam parameters set by the user by operating a terminal device (such as a mobile phone, a tablet computer) that is connected to the washing device for communication, etc. Such adjustments and changes to the specific method of obtaining the preset foam parameters set by the user do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0047] Exemplarily, the washing device of the present invention is provided with buttons, and the user obtains the preset foam parameters set by the user by operating the buttons on the washing device.

[0048] It should be noted that, in actual applications, those skilled in the art may set the preset foam parameters to preset foam amounts, or may set the preset foam parameters to preset foam amount levels, etc. Such adjustments and changes to the specific setting types of the preset foam parameters do not deviate from the principles and scope of the present invention, and should be included in the protection scope of the present invention.

[0049] In a specific embodiment, the preset foam parameter is a preset foam amount. A preset pH value corresponding to the preset foam amount is first obtained, and the pH value of the washing solution is selectively adjusted according to the actual pH value and the preset pH value.

[0050] In another specific embodiment, the preset foam parameter is a preset foam amount level, and a preset pH value range corresponding to the preset foam amount level is first obtained, and the pH value of the washing solution is selectively adjusted according to the actual pH value and the preset pH value range.

[0051] Preferably, the preset foam parameter is a preset foam amount level.

[0052] The step of "obtaining preset foam parameters set by the user" specifically includes:

[0053] S21: Obtaining a preset foam volume level set by a user;

[0054] The step of “selectively adjusting the pH value of the washing solution according to the actual pH value and the preset foam parameters” specifically includes:

[0055] S31: Obtaining a preset pH value range corresponding to a preset foam amount level;

[0056] The pH value of the washing solution is selectively adjusted according to the actual pH value and the preset pH value range.

[0057] Through such a setting, compared with first obtaining a preset pH value corresponding to a preset foam amount, and selectively adjusting the pH of the washing solution according to the actual pH value and the preset pH value, by first obtaining a preset pH value range corresponding to a preset foam amount level, and then selectively adjusting the pH of the washing solution according to the actual pH value and the preset pH value range, on the one hand, it can avoid misjudgment caused by detection errors of the pH detection sensor, and on the other hand, it can also reduce the pH adjustment of the washing solution as much as possible on the basis of satisfying the user's preference for the amount of washing foam, thereby further improving the user's experience.

[0058] In a specific embodiment, the foam amount during washing with washing solutions of different pH values ​​is tested to obtain a corresponding relationship table between different pH values ​​and foam amounts, and the preset pH value range corresponding to the preset foam amount level is obtained by looking up the table.

[0059] In another specific embodiment, the amount of foam during washing with washing solutions having different pH values ​​is first tested to obtain multiple sets of pH value and foam amount data, and then a fitting function regarding pH value and foam amount is obtained based on the multiple sets of pH value and foam amount data. According to the fitting function, pH value thresholds corresponding to the minimum foam amount and the maximum foam amount are obtained respectively, and a preset pH value range corresponding to the preset foam amount level is obtained based on the obtained pH value thresholds.

[0060] It should be noted that, although the above two embodiments can both obtain the pH value range corresponding to the preset foam amount level, compared with obtaining the preset pH value range corresponding to the preset foam amount level by looking up a table, obtaining the preset pH value range corresponding to the preset foam amount level according to the fitting function can make the acquisition of the preset pH value range more accurate, so that the foam generated in the actual washing process can be more consistent with the preset foam amount set by the user, further improving the user experience.

[0061] It should also be noted that, in actual applications, those skilled in the art can directly determine whether the actual pH value is within the preset pH value range, and selectively adjust the pH value of the washing solution based on the judgment result, or first calculate the difference between the actual pH value and the pH threshold of the preset pH value range, and then compare the difference with the preset value, and selectively adjust the pH value of the washing solution based on the comparison result, or first calculate the ratio between the actual pH value and the pH threshold of the preset pH value range, and then compare the ratio with the preset value, and selectively adjust the pH value of the washing solution based on the comparison result, etc. Such flexible adjustments and changes do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0062] Preferably, the step of "selectively adjusting the pH value of the washing solution according to the actual pH value and the preset pH value range" specifically includes:

[0063] S32: Determine whether the actual pH value is within the preset pH value range;

[0064] Based on the judgment result, the pH of the washing solution is selectively adjusted.

[0065] Through such a setting, compared with the method of first calculating the difference between the actual pH value and the threshold of the preset pH value range, and then comparing the difference with the preset value, and selectively adjusting the pH value of the washing solution according to the comparison result, directly judging whether the actual pH value is within the preset pH value range, and selectively adjusting the pH value of the washing solution according to the judgment result, can more accurately and intuitively judge whether the actual pH value of the washing solution is in line with the preset pH value range corresponding to the preset foam parameters selected by the user, and thus can more accurately make the amount of foam generated by the washing solution during the washing process meet the user's washing needs, further improving the user's usage experience.

[0066] Preferably, the step of "selectively adjusting the pH of the washing solution according to the judgment result" specifically includes:

[0067] S33: If the judgment result is "No", the pH of the washing solution is adjusted.

[0068] Through such a setting, when the judgment result is "no", it means that the actual pH value is not within the preset pH value range. If the pH value of the washing solution is not adjusted, the amount of foam generated in the actual washing process will be quite different from the preset foam amount set by the user. At this time, timely adjusting the pH value of the washing solution can make the actual pH value closer to the preset pH value range, thereby making the amount of foam generated in the actual washing process closer to the preset foam amount set by the user, thereby improving the user experience.

[0069] It should be noted that, in actual applications, when the pH value of the washing solution needs to be adjusted, a prompt can be issued to the user to prompt the user to adjust the pH value of the washing solution, or the washing equipment includes a pH adjustment module, and when the pH value of the washing solution needs to be adjusted, the pH value of the washing solution can also be adjusted by the pH adjustment module of the washing equipment, and so on. Such adjustments and changes to the specific adjustment method for adjusting the pH value of the washing solution do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0070] Preferably, the washing device of the present invention comprises a pH value adjustment module, and the step of "adjusting the pH value of the washing solution" comprises:

[0071] The pH value of the washing solution is adjusted by the pH value adjustment module.

[0072] Through such a setting, compared with the form of prompting the user to adjust the pH value of the washing solution, the pH value of the washing solution is adjusted by the pH adjustment module on the washing equipment, which can automatically adjust the pH value of the washing solution, thereby making the washing equipment more intelligent and further improving the user experience.

[0073] It should be noted that, in actual applications, those skilled in the art may configure the pH value adjusting module to be an electrolysis module, which can electrolyze the washing solution to change the pH value of the washing solution, or, the pH value adjusting module may be configured to be an ion exchange module, which can cause ion exchange in the washing solution to change the pH value of the washing solution, or, the pH value adjusting module may be configured to include an acid storage tank and an alkali storage tank, wherein the acid is stored in the acid storage tank, and the alkali is stored in the alkali storage tank, and a certain amount of acid or alkali is added to the washing solution to adjust the pH value of the washing solution, and so on. Such adjustments and changes to the specific setting types of the pH value adjusting module do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0074] Preferably, the pH value regulating module is configured as an electrolysis module, and the electrolysis module can electrolyze the washing solution to change the pH value of the washing solution.

[0075] Through such a setting, compared with the form of adding a certain amount of acid or alkali solution to the washing solution to adjust the pH value of the washing solution, setting the pH value adjustment module in the form of an electrolysis module can further improve the intelligent operation of pH value adjustment. There is no need for users to put acid or alkali solution into the acid storage tank and the alkali storage tank, thereby further improving the user experience.

[0076] It should be noted that the pH of the washing solution can be adjusted based on experience, or the actual pH value can be adjusted. x PH max and PH min A comparison is made and, based on the comparison result, the pH value of the washing solution is selectively adjusted up or down, etc. Such adjustment and change of the specific method of adjusting the pH value of the washing solution does not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

[0080] Among them, PH max The maximum pH value within the preset pH range. min It is the minimum pH value within the preset pH range.

[0081] By such a setting, the actual pH value is adjusted by comparing the pH value of the washing solution according to experience. x PH max and PH min By making a comparison and selectively adjusting the pH value of the washing solution higher or lower according to the comparison result, it is possible to accurately determine whether the actual pH value is lower or higher than the preset pH value range, and then accurately adjust the pH value of the washing solution according to the comparison result to improve the adjustment efficiency.

[0082] Preferably, the step of "selectively increasing or decreasing the pH value of the washing solution according to the comparison result" specifically includes:

[0083] S332: If PH x >PH max , then lower the pH value of the washing solution;

[0084] S333: If PH x <PH min , then increase the pH value of the washing solution.

[0085] By setting this up, when the actual pH value is greater than pH max In the case of , it means that the actual pH value is higher than the preset pH value range. At this time, lowering the pH value of the washing solution can make the actual pH value within the preset pH value range. min In the case of, it means that compared with the preset pH value range, the actual pH value is lower. At this time, increasing the pH value of the washing solution can make the actual pH value within the preset pH value range, thereby making the amount of foam generated in the actual washing process match the preset foam amount level selected by the user, thereby meeting the user's washing needs.

[0086] Preferably, in the process of adjusting the pH value of the washing solution, the control method of the present invention further comprises:

[0087] S41: obtaining the current pH value of the washing solution in real time;

[0088] S42: Determine whether the current pH value reaches a preset pH value range;

[0089] According to the judgment result, the pH value adjustment of the washing solution is selectively terminated.

[0090] Through such a setting, in the process of adjusting the pH value of the washing solution, the current pH value of the washing solution is obtained in real time to determine whether the current pH value reaches the preset pH value range, and the pH value adjustment of the washing solution is selectively ended according to the judgment result. The pH value of the washing solution can be gradually adjusted, so that the pH of the washing solution can be adjusted more quickly and accurately, thereby improving the adjustment efficiency and adjustment accuracy of the pH value adjustment, and further enhancing the user experience.

[0091] Preferably, the step of "selectively ending the pH adjustment of the washing solution according to the judgment result" specifically includes:

[0092] S421: If the judgment result is "yes", the pH value adjustment of the washing solution is terminated.

[0093] Through such a setting, when the judgment result is "yes", it means that the current pH value has reached the preset pH value range, that is, the amount of foam generated during the washing process is consistent with the preset foam amount level set by the user. At this time, the pH adjustment of the washing solution is ended, which can improve the adjustment efficiency of the pH value and further enhance the user experience.

[0094] It should be noted that, when the pH value of the washing solution is adjusted, the control method of the present invention further includes the following steps:

[0097] S422: If the judgment result is "No", the pH value adjustment of the washing solution is not terminated.

[0098] Through such a setting, when the judgment result is "no", it means that the current pH value has not reached the preset pH value range. At this time, the pH value adjustment of the washing solution is not terminated, and the pH value of the washing solution can be further adjusted to adjust the pH value of the washing solution to the preset pH value range, thereby making the amount of foam generated by washing match the preset foam amount level selected by the user.

[0099] Preferably, when the judgment result is "No", return to step S41.

[0100] In this way, the current pH value of the washing solution can continue to be detected, and it can be further determined whether the current pH value is within the preset pH value range, thereby accurately completing the pH value adjustment of the washing solution.

[0101] The specific adjustment process for adjusting the pH value of the washing solution is described in detail below in conjunction with the following situations.

[0102] Set the preset pH range to: pH x ≤8.0.

[0104] If PH is detected at a certain moment 1 =8.3>8.0, the pH adjustment of the washing solution is not terminated, that is, the pH value of the washing solution is continued to be lowered, and the current pH value of the washing solution is detected in real time. If the current pH value is detected to be PH 2 =7.8<8.0, then the pH value adjustment of the washing solution is terminated.

[0106] S34: If the judgment result is "yes", the pH value of the washing solution is not adjusted.

[0107] Through such a setting, when the judgment result is "yes", it means that the actual pH value is within the preset pH value range. At this time, the pH value of the washing solution does not need to be adjusted, so that the actual amount of foam generated in the actual washing process can be consistent with the preset foam amount level, further improving the user experience.

[0119] 10 parts of fatty alcohol polyoxyethylene ether, 12 parts of dodecylbenzene sulfonic acid, 15 parts of fatty alcohol polyoxyethylene ether sodium sulfate, 10 parts of branched oil vinyl ether and amine ether, 1 part of sodium citrate, 4 parts of dispersant, 2 parts of complex enzyme, 4 parts of liquid alkali, 1.5 parts of flavor, 0.05 parts of blue pigment, 0.05 parts of defoaming agent, 0.5 parts of preservative, 3 parts of propylene glycol, 7 parts of ethanol, 29.9 parts of deionized water, pH value (1% aqueous solution) equals 8.0.

[0120] It should be noted that branched oil vinyl ether and amine ether can be purchased from Guangzhou Qinxiang Chemical Co., Ltd., and the product name is branched oil vinyl ether and amine ether.

[0121] Test example:

[0122] Take an appropriate amount of the detergent of Example 1 to Example 3 and add it to the washing machine, take 3 kg of polyester-cotton (4:9) mixed fabric as the load, make the load into contaminated cloth according to the European standard as the washing object, select the 10 kg machine smart wash default program for washing, wherein the washing temperature is 30°C, the speed is 800 rpm, the main wash is 1 time, the rinse is 2 times, and the total washing time is 62 minutes.

[0123] Observe the amount of foam produced during the main wash and adjust the amount of foam according to the Figures 3 to 5To rate the state of foam produced during washing.

[0124] Specifically, if Figure 3 As shown, the height of the highest foam volume is greater than 2 / 3 of the entire barrel window, and the foam volume is rated as "rich";

[0125] like Figure 4 As shown, the highest foam volume is between 1 / 3 and 2 / 3 of the entire barrel window, and the foam volume is rated as "moderate";

[0126] like Figure 5 As shown, the height of the highest foam amount is less than 1 / 3 of the entire barrel window, and the foam amount is rated as "small amount".

[0127] After testing, the amount of foam produced by Example 1 is as follows Figure 3 As shown, the detergent of Example 1 can produce abundant foam, and the amount of foam produced by Example 2 is as follows. Figure 4 As shown, the amount of foam produced by the detergent of Example 2 is moderate, and the amount of foam produced by Example 3 is as follows. Figure 5 As shown, the detergent in Example 2 can generate a small amount of foam.

[0128] It can be seen that as the pH value of the detergent changes, the amount of foam generated by the detergent during use also changes. Since the amount of detergent and the amount of water in the above-mentioned embodiments are equal, the pH value of the detergent also determines the pH value of the washing solution, that is, the amount of foam that the detergent can generate during the washing process changes with the change of the pH value of the washing solution.

[0129] The specific embodiments of the control method for washing equipment of the present invention are described in detail below in combination with the above-mentioned detergent and in the following situations.

[0130] After testing, the relationship between the preset pH value of the washing solution and the preset foam amount is as follows:

[0131] The preset pH value range corresponding to the preset foam volume level (rich) is: x >8.5;

[0132] The preset pH value range corresponding to the preset foam volume level (moderate) is: 8.0≤PH x ≤8.5;

[0133] The preset pH value range corresponding to the preset foam amount level (small amount) is: x <8.0.

[0134] Scenario 1:

[0135] If the preset foam level selected by the user is rich, the preset pH value range corresponding to the preset foam level is: pH x >8.5.

[0136] (1) If the actual pH value of the washing solution is detected as PH x =7.8<8.5, the actual pH value is not within the preset pH value range, and the pH of the washing solution is adjusted at this time;

[0137] Because PH x =7.8<8.5, then adjust the pH value of the washing solution higher.

[0138] (2) If the actual pH value of the washing solution is detected to be pH x =8.6>8.5,

[0139] The actual pH value is within the preset pH value range, and the pH of the washing solution is not adjusted at this time.

[0140] Scenario 2:

[0141] If the preset foam volume level selected by the user is moderate, the preset pH value range corresponding to the preset foam volume level is: 8.0≤PHx≤8.5.

[0142] (1) If the actual pH value of the washing solution is detected as PH x =7.6<8.0, the actual pH value is not within the preset pH value range, and the pH of the washing solution is adjusted at this time;

[0143] Because PH x =7.6<8.0, then adjust the pH value of the washing solution higher.

[0144] (2) If the actual pH value of the washing solution is detected to be pH x =8.2,8.0≤PH x =8.2≤8.5, the actual pH value is within the preset pH value range, and the pH of the washing solution is not adjusted at this time.

[0145] (3) If the actual pH value of the washing solution is detected to be pH x =8.8>8.5, the actual pH value is not within the preset pH value range, and the pH of the washing solution is adjusted at this time;

[0146] Because PH x =8.8>8.5, then lower the pH value of the washing solution.

[0147] Scenario 3:

[0148] If the preset foam volume level selected by the user is a small amount, the preset pH value range corresponding to the preset foam volume level is: pH x <8.0.

[0149] (1) If the actual pH value of the washing solution is detected as PH x =7.6<8.0, the actual pH value is within the preset pH value range, and the pH of the washing solution is not adjusted at this time.

[0150] (2) If the actual pH value of the washing solution is detected to be pH x =8.5>8.0, the actual pH value is not within the preset pH value range, and the pH of the washing solution is adjusted at this time;

[0151] Because PH x =8.5>8.0, then lower the pH value of the washing solution.
