Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of mechanical equipment, in particular, relates to a control method of a washing equipment and the washing equipment. BACKGROUND

[0002] The "washing equipment" refers to a general term of a kind of household appliances capable of executing a washing program, such as a dishwasher, a washing machine and the like. The washing equipment needs to put detergent when executing the washing program, and the detergent generates foam for assisting in washing the objects to be cleaned. For example, when washing clothes using the washing machine, the detergent needs to be put into the washing machine to clean the clothes.

[0003] The main component of the detergent is non-ionic surfactant, which can effectively remove dirt from the fabric. The non-ionic surfactant is mostly in liquid and slurry state, and its solubility in water decreases with the increase of temperature. When reaching a certain temperature, the non-ionic surfactant becomes insoluble and precipitates into turbid liquid.

[0004] At present, the ways of putting detergent into the washing equipment (such as a washing machine) include manual putting and automatic putting. When the user chooses manual putting, the detergent cannot be accurately put according to the weight or the dirtiness of the clothes to be washed, which may cause the detergent to be put in excess, making it difficult to rinse and leaving the detergent on the clothes.

[0005] When the user chooses automatic putting, the washing equipment controls the detergent putting box to automatically put the detergent according to the information of the weight or the amount of water of the clothes. During the putting process, the same setting proportion of the detergent is mechanically put regardless of the type or the concentration of the detergent. However, in fact, the concentrations of the effective components in different brands of the detergent are not the same. Therefore, the automatic putting of the detergent in this way may cause the detergent to be put in excess, making it difficult to rinse, or the detergent to be put in insufficient, failing to achieve the cleaning effect.

[0006] At present, some washing equipment increases the number of rinsing to rinse the objects to be cleaned for multiple times when the detergent is put in excess, in order to ensure that there is no much detergent left on the objects to be cleaned. This method not only causes the waste of the detergent, but also causes the waste of water resources, electric resources and the like.

[0007] Therefore, the present application is proposed. SUMMARY

[0043] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments will be described clearly and completely below in conjunction with the drawings of the embodiments of the present application. The following embodiments are used to illustrate the present application, but not to limit the scope of the present application.

[0044] In the description of the present application, it should be noted that the terms “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inner”, “outer” and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0045] ​In the description of the present application, it should be noted that unless specifically defined and limited otherwise, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0046] As Figures 1 to 5 indicated, the present application provides a control method of a washing device and a washing device. The washing device refers to a general term of a kind of household appliances capable of performing a washing program, such as a dishwasher, a washing machine, etc. The washing device comprises a containing cavity 1 for containing washing water.

[0047] The control method of the washing device comprises:

[0048] obtaining a concentration S of a detergent in the washing water in the containing cavity 1;

[0049] If the obtained concentration S is greater than a preset concentration S0, the control separates and extracts the detergent in the washing water.

[0050] Specifically, as Figure 1 indicated, the control method of the washing device comprises:

[0051] S1, presetting a concentration S0;

[0052] S2, obtaining a concentration S of a detergent in the washing water in the containing cavity 1;

[0053] S3, judging whether the obtained concentration S is greater than the preset concentration S0;

[0054] S4, if yes, controlling to separate and extract the detergent in the washing water, and repeating steps S2 to S4; otherwise, executing step S5;

[0055] S5, judging whether the obtained concentration S is equal to the preset concentration S0;

[0056] S6, if yes, judging that the detergent dosage is appropriate, and controlling to end the dosing program; otherwise, controlling to supplement the detergent into the containing cavity 1, and repeating steps S2 to S6.

[0057] In the present application, if the obtained concentration S is greater than the preset concentration S0, it indicates that the detergent dosage is excessive, the control separates and extracts the detergent in the washing water, which reduces the concentration of the detergent in the washing water, avoids the residual detergent on the washing object without increasing the number of rinsing, and effectively saves the water resource and the electric resource. The separated detergent can be used for the next washing, which avoids the waste of the detergent.

[0058] As an embodiment of the present application, the separation and extraction comprises: controlling to discharge part of the washing water from the containing cavity 1, and separating and extracting the washing agent in the discharged washing water.

[0059] Specifically, as shown in the figure, the control method of the washing device comprises: Figure 2

[0060] S1, presetting a concentration S0;

[0061] S2, obtaining a concentration S of the washing agent in the washing water in the containing cavity 1;

[0062] S3, judging whether the obtained concentration S is greater than the preset concentration S0;

[0063] S4, if yes, controlling to discharge part of the washing water from the containing cavity; otherwise, executing step S7;

[0064] S5, controlling to feed water into the containing cavity;

[0065] S6, separating and extracting the washing agent in the discharged washing water, and repeating steps S2 to S6;

[0066] S7, judging whether the obtained concentration S is equal to the preset concentration S0;

[0067] S8, if yes, judging that the amount of the washing agent is appropriate, and controlling to end the feeding program; otherwise, controlling to supplement the washing agent into the containing cavity 1, and repeating steps S2 to S8.

[0068] In the embodiment, when it is judged that the obtained concentration S is greater than the preset concentration S0, it indicates that the amount of the washing agent is excessive, and a large amount of foam is likely to be generated. At this time, part of the washing water is discharged to reduce the content of the washing agent in the containing cavity 1, so as to avoid that the amount of the foam generated in the containing cavity 1 is too large, and thus a large amount of the washing agent is left on the object to be cleaned.

[0069] As an embodiment of the present application, step S4 comprises:

[0070] S41, controlling to calculate a difference value AS between the obtained concentration S and the preset concentration S0;

[0071] S42, presetting a database corresponding to the difference value AS and the discharge amount of the washing water, and obtaining the corresponding discharge amount of the washing water from the database according to the calculated difference value AS.

[0072] In the embodiment, by setting the database, a reasonable discharge amount of the washing water can be obtained according to the difference value AS, so that the discharge amount of the washing water is relatively accurate, the discharge amount of the washing water is not too large to reduce the washing effect, and the discharge amount of the washing water is not too small to leave the washing agent on the object to be cleaned.

[0073] ​As another embodiment of the present embodiment, step S4 comprises:

[0074] S41', controlling the difference AS of the calculated concentration S and the preset concentration SO;

[0075] S42', presetting an operation model "discharge volume V=K*AS", bringing the calculated difference AS into the operation model to obtain the discharge volume V. The operation model is set before the washing equipment is shipped.

[0076] In the present embodiment, by bringing the difference AS into the operation model, the washing water discharge volume V corresponding to the difference AS can be accurately obtained, so that the washing water discharge volume V is relatively more accurate, avoiding excessive washing water discharge volume and reducing the washing effect; the washing water discharge volume is less, and the detergent remains on the washing object.

[0077] As another embodiment of the present application, as shown in Figure 3 the separation and extraction further comprises:

[0078] controlling the heating of the discharged washing water, and controlling the filtration and separation of water and detergent in the heated washing water.

[0079] In the present embodiment, since the main component of the detergent is a non-ionic surfactant, its solubility in water decreases with the increase of temperature, and when a certain temperature is reached, it becomes insoluble and precipitates into a turbid liquid. The formed turbid liquid is filtered and separated to obtain water and detergent.

[0080] As an embodiment of the present embodiment, the separated water is controlled to be transported back into the containing cavity 1.

[0081] In the present embodiment, the separated water is transported back into the containing cavity 1, so that this part of water can dilute the washing water in the containing cavity 1 to reduce the concentration of the detergent in the washing water. Moreover, the present embodiment makes full use of the separated water, avoiding waste of water resources.

[0082] As another embodiment of the present embodiment, the separated water is controlled to be discharged out of the washing equipment. The present embodiment has a simple control process and high efficiency of discharging water.

[0083] As still another embodiment of the present embodiment, the washing equipment comprises a dispensing box for dispensing detergent into the containing cavity 1, and the separated detergent is controlled to be transported to the dispensing box.

[0084] In the present embodiment, the separated detergent is controlled to be transported to the dispensing box, which facilitates the subsequent use of the part of detergent according to the actual needs in the subsequent washing process, avoiding waste of detergent.

[0085] In one embodiment of the present invention, when executing the detergent dispensing procedure, the concentration S is controlled to be obtained.

[0086] Specifically:

[0087] After turning on the washing equipment, control the water to enter the receiving chamber 1;

[0088] After the water intake is complete, control the pre-set amount of detergent to be added;

[0089] Obtain the detergent concentration S in the washing water within the receiving cavity 1;

[0090] If the obtained concentration S is the same as the preset concentration S0, the detergent dispensing process is completed.

[0091] If the obtained concentration S is less than the preset concentration S0, it indicates that the amount of detergent added is insufficient. Add more detergent to ensure that the items to be washed can be cleaned.

[0092] After the detergent dispensing process is complete, the washing program will begin.

[0093] In this embodiment, when executing the detergent dispensing procedure, the concentration S of the detergent in the washing water of the receiving cavity 1 is controlled to ensure that the amount of detergent dispensed during the detergent dispensing process can meet the washing requirements without being excessive. This improves the accuracy of detergent dispensing when executing the detergent dispensing procedure and is beneficial to the effective execution of subsequent washing procedures.

[0094] As one implementation of this embodiment, when the detergent dispensing procedure is executed subsequently, if the obtained concentration S is less than the preset concentration S0, the separated and extracted detergent is controlled to be dispensed into the receiving cavity 1.

[0095] In this embodiment, the separated and extracted detergent is effectively utilized in the subsequent detergent dispensing process, thus avoiding waste of detergent.

[0096] In one embodiment of the present invention, the preset concentration S0 is related to the quantity and degree of soiling of the items to be washed in the washing equipment. The greater the quantity of items to be washed, the higher the preset concentration S0, so as to ensure that the detergent added can clean the items thoroughly.

[0097] Specifically, after the items to be washed are placed in the washing equipment, an infrared spectrometer installed on the washing equipment scans the items; the scanned data is compared with the parameters of standard items to be washed in the database to determine the degree of dirtiness of the items to be washed, thereby determining the preset concentration S0.

[0098] In this embodiment, the concentration S0 is reasonably preset according to the item to be washed, so that the washing water corresponding to the detergent concentration can clean the item.

[0099] As an embodiment of the present application, the detergent concentration detector is used to obtain the detergent concentration S in the washing water in the containing cavity 1.

[0100] Specifically, the detergent concentration detector collects the spectral data of the washing water in the containing cavity 1 and generates the corresponding spectral graph. The detergent concentration detector detects the measured liquid based on transmission molecular spectral analysis. Each substance molecule in the measured liquid has a unique absorption effect on light of a specific wavelength range, which is due to the chemical bonds in the molecule. Since each molecule contains chemical bonds that are different from each other, each molecule has its own unique "spectral fingerprint".

[0101] When detecting, the detergent concentration detector needs to pass the light beam through the measured liquid, record the relationship curve between the light transmission ratio and the wave number or wavelength, and then obtain the spectral graph. Then, by combining with a suitable data model, the absorption spectrum and the standard spectrum are compared to determine which substance is contained.

[0102] By comparing the spectral data with the standard spectrum through the spectral analysis module, the substance molecules contained in the washing water and the absorbance of each substance molecule are determined, and the absorbance of the hydrocarbon chain in the washing water is obtained. According to the Lambert-Beer absorption law, the concentration of the hydrocarbon chain in the washing water is obtained by using the linear relationship between the absorbance of the substance molecule and its concentration, and then the concentration S of the non-ionic surfactant in the washing water, i.e. the concentration of the detergent, is obtained.

[0103] The present application also provides a washing device controlled by the control method described in any of the above technical solutions. The washing device of the present application is controlled by the control method of the present application, which reduces the waste of detergents, water resources and electric resources.

[0104] Specifically, as shown in Figure 4 The washing device of the present application takes a drum washing machine as an example, and the washing device comprises a separation device 2. The separation device 2 is in communication with the containing cavity 1 and is used to separate and extract the detergent in the washing water in the containing cavity 1.

[0105] The present application provides a separation device 2 on the washing device, so that the separation device 2 can separate and extract the detergent in the washing water, reduce the concentration of the detergent in the washing water, and avoid the residual detergent on the laundry without increasing the number of rinsing, thereby effectively saving water resources and electric resources. The detergent separated by the present application can be used for next washing, thereby avoiding the waste of detergent.
