Description

Technical Field

[0001] The present invention belongs to the field of clothing care agent delivery equipment, and in particular, relates to a clothing care additive delivery equipment and a control method thereof. Background Art

[0002] With the development of economy and the improvement of people's living standards, washing machines have entered more and more families. People have higher and higher requirements on the performance and functions of washing machines, and the intelligent level of washing machines is also getting higher and higher. Low-end fully automatic washing machines generally do not have the function of automatic detergent dispensing. Only high-end washing machine products have the automatic dispensing function. Most washing machines sold on the market now require users to manually add detergent to the detergent box in advance, and the washing machine then flushes the detergent into the washing drum by flushing water according to the washing process.

[0003] In order to enable ordinary washing machines that have been sold to have the function of automatic detergent dispensing, the Chinese patent with application number 201922110159.X provides a universal detergent automatic dispensing device external to the washing machine, including a dispensing device body, a circuit detector and a dispensing pipeline, one end of the dispensing pipeline is connected to the dispensing device body, and the other end is connected between the faucet and the water inlet pipe of the washing machine; the circuit detector is provided with a power detection module for detecting the operating status information of the washing machine, the input end of the circuit detector is electrically connected to the washing machine, and the output end of the circuit detector is electrically connected to the dispensing device body; the circuit detector is provided with pins and jacks, which can be conveniently connected directly to the household power socket and the washing machine; the current, voltage and power of the washing machine are detected by the circuit detector, and the water inlet status and water inlet amount information of the flow detector are combined to realize the automatic dispensing function of the ordinary washing machine.

[0004] The universal automatic detergent dispensing device in the above scheme can only realize automatic detergent dispensing based on the working status of the washing machine. It has a single function and cannot meet the user's intelligent demand for automatic detergent dispensing equipment. Moreover, in any region and any environment, the amount of detergent dispensed only changes with the water intake.

[0005] While my country's total water resources are very abundant, the water quality distribution is very uneven. Different water quality actually has a great impact on the washing of clothes, because relatively hard water will react with detergents to produce some water-insoluble substances. On the one hand, the products will damage the clothes, and on the other hand, some detergents will react with substances in the water to reduce the concentration of detergents, resulting in poor washing effects. Therefore, it is urgent to solve the problem of enabling automatic detergent dispensing equipment to intelligently dispense the right amount of detergent according to different water qualities.

[0006] In view of this, the present invention is proposed. Summary of the invention

DETAILED DESCRIPTION

[0053] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0054] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0055] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0056] like Figures 1 to 3 As shown, the present invention provides a washing and care additive delivery device and a control method thereof, wherein Figure 1 As shown, the washing and care additive delivery device 100 includes a first acquisition unit 101, a processing unit 105 and a communication unit 104. The first acquisition unit 101 is used to acquire the water hardness of the geographical area where the delivery device is located; the processing unit 105 is connected to the acquisition unit, receives the water hardness acquired by the acquisition unit, and adjusts the washing and care program of the washing and care additive delivery device 100 according to the water hardness; the communication unit 104 sends the washing and care program generated by the processing unit 105 to the clothing processing device 200.

[0057] The washing and care additive delivery device 100 also includes a control unit 103, a delivery waterway, and a plurality of liquid storage box installation chambers for installing liquid storage boxes for holding different types of washing and care additives. A delivery pipeline is provided between each liquid storage box installation chamber and the delivery waterway. The two ends of the delivery pipeline are respectively connected to the liquid storage box and the delivery waterway. A delivery mechanism 102, such as a liquid pump, is provided on the delivery pipeline. The control unit 103 controls the delivery mechanism 102 to deliver washing and care additives into the delivery waterway. The washing and care additive delivery device 100 also includes a flow sensor for detecting the water intake of the clothing processing device 200, and the flow sensor is provided on the delivery waterway.

[0058] When in use, the water inlet end of the water supply channel is connected to the tap water connector, and the water outlet end of the water supply channel is connected to the water inlet of the clothing processing device 200 .

[0059] When the automatic dispensing process of the washing and care additives in the washing and care program is running, the water inlet valve of the clothes processing device 200 is opened, and the water from the tap water joint passes through the dispensing water channel of the washing and care additive dispensing device 100, and then enters the clothes processing device 200 from the water inlet of the clothes processing device 200. The dispensing mechanism 102 dispenses the washing and care additives in the liquid storage box into the dispensing water channel, so that the washing and care additives enter the clothes processing device 200 together with the tap water in the dispensing water channel.

[0060] Detailed, such as Figure 2 As shown, the control method of the laundry additive dispensing device 100 includes the following steps: obtaining the water hardness of the geographical area where the dispensing device is located; adjusting the laundry program of the laundry additive dispensing device 100 according to the water hardness; and transmitting the adjusted laundry program to the clothing processing device 200.

[0061] Specifically, water hardness refers to the amount of calcium, magnesium, iron, aluminum, zinc and other ions contained in water, usually calculated as Ca2+ and Mg2+ content. There are two units, one is expressed in milligram equivalents / liter, and the other is expressed in degrees. That is, 10 mg of Ca in 1 liter of water is 1 degree. 0-4 degrees is very soft water, 4-8 degrees is soft water, 8-16 degrees is moderately hard water, and 16-30 degrees is hard water.

[0062] Different water hardness actually has a great impact on the cleaning of clothes, because water with relatively high hardness will react with detergent additives to produce some water-insoluble substances. On the one hand, the products cause damage to clothes, and on the other hand, some detergent additives react with substances in the water to reduce the concentration of detergent additives, resulting in poor cleaning effect.

[0063] The control method of the present invention can adjust the washing program according to the water hardness of the area where the washing additive dispensing device 100 is located, and enable the clothing processing device 200 to wash the clothes cleanly regardless of the water quality when using the washing program sent by the washing additive dispensing device 100 to achieve the best washing effect.

[0064] In a further solution, adjusting the washing and care program of the washing and care additive delivery device 100 according to the water hardness includes: adjusting the type of washing and care additives delivered in the washing and care program and / or the delivery ratio of the washing and care additives and / or the delivery timing of the washing and care additives.

[0065] Specifically, different laundry additives have different ingredients and uses, and users usually purchase corresponding types of laundry additives according to their family's needs. Moreover, with the development of chemical technology, there will be more and more types of laundry additives suitable for clothing care, and the requirements for using laundry additives to care for clothes are also getting higher and higher. Different water hardnesses need to match different types of laundry additives, different proportions of laundry additives, and different timings of laundry additives. The present invention adjusts the type of laundry additives and / or the proportion of laundry additives and / or the timing of laundry additives by water hardness, so as to better wash and care for clothes.

[0066] Preferably, the types of the washing and care additives include main detergents and auxiliary detergents, the main detergents include various types of detergents; auxiliary detergents are functionally divided into water softeners, bleaches, disinfectants, fragrance enhancers, etc.

[0067] Whether it is the main detergent or the auxiliary detergent, it can be divided into acidic detergent additives, neutral detergent additives and alkaline detergent additives from the perspective of acidity and alkalinity.

[0068] From the perspective of ingredients, main detergents can be divided into soap-based detergents and non-soap-based detergents.

[0069] Different types, ingredients, and pH levels of cleaning additives are suitable for different water hardnesses.

[0070] For example, soap-based detergents have sodium stearate as their main ingredient, which is produced through saponification of natural oils and fats. They have strong detergency and good biodegradability, are non-toxic to the human body, and do not pollute the environment. However, soap-based detergents easily undergo a replacement reaction with calcium and magnesium ions in hard water to form soap scum, which adheres to clothing, causing the washed clothing to become hardened, and forms dirt on washing utensils.

[0071] It can be seen that if the water hardness of the geographical area where the dispensing device is located is obtained as hard water, the automatic dispensing of soap-based detergent preset in the washing and care program can be adjusted to automatic dispensing of non-soap-based detergent.

[0072] It is also possible to adjust the automatic soap-based detergent dispensing preset in the washing program to automatically dispense soap-based detergent and water softener or fabric softener or laundry neutralizer at the same time.

[0073] Moreover, for areas with high hardness water, it is best to add water softener in each washing step, while softener and laundry neutralizer can be added in the final rinsing step. Therefore, when the preset automatic soap-based detergent in the washing program is adjusted to automatically add soap-based detergent and water softener or laundry neutralizer or softener at the same time, the timing of adding water softener or laundry neutralizer or softener should also be adjusted.

[0074] It is also possible, without adjusting the type of automatic soap-based detergent dispensed in the washing and care program, but adjusting the proportion of automatic soap-based detergent dispensed in the washing and care program.

[0075] Preferably, the hardness of the water in areas with softer water is 0.8g / L, that in areas with moderate water hardness is 1.0g / L, and that in areas with harder water hardness is 1.2g / L; for example, if the laundry additive dispensing device 100 is used in Nanjing, the first acquisition unit 101 obtains this location and uploads it to the processing unit 105, and the processing unit 105 automatically searches and matches Nanjing as an area with higher water hardness, and the dispensing ratio adopted is 1.2g / L, so when the clothing processing device 200 is running, for every 1L of water taken in, the laundry additive dispensing device 100 will dispense 1.2g of laundry additives.

[0076] In the above scheme, adjusting the proportion of the washing and care additives in the washing and care program is to adjust the proportion of the washing and care additives according to the water inlet flow rate. The washing and care additive delivery device 100 of the present invention delivers washing and care additives in a process of delivering a certain amount of washing and care additives for each certain amount of water inlet, and delivers the washing and care additives directly into the delivery waterway, so as to achieve mixing of the washing and care additives and water in the delivery waterway.

[0077] For example, when it is detected that the water hardness of the geographical area where the washing and care additive delivery device 100 is located is hard water, the delivery ratio of the detergent should be adjusted to match the hard water. In one embodiment, if the default delivery ratio is 1g / L, the delivery ratio of the detergent matching hard water is 1.2g / L. That is, when the flow sensor detects that the water inlet flow rate reaches 1L, the liquid pump is controlled to extract 1.2g of detergent from the liquid storage box into the delivery water channel, which is a delivery interval. When the flow sensor detects that the water inlet flow rate reaches 1L again, the liquid pump is controlled to extract 1.2g of detergent from the liquid storage box into the delivery water channel again. This cycle repeats until the detergent extracted by the liquid pump reaches the delivery amount required in the washing and care program, and the delivery process ends, and the delivery water channel only supplies water to the clothing processing device 200.

[0078] In the above scheme, the detergent additives are added multiple times during the entire water intake process, so that the detergent additives are more easily evenly distributed in the water, thereby achieving a better washing effect. In addition, the addition chamber in the prior art is omitted, so that the product size of the detergent additive delivery device 100 of the present invention is smaller, which better meets the needs of users.

[0079] In a further solution, the control method of the cleaning additive dispensing device 100 also includes obtaining information about the cleaning additives; determining whether there is at least one cleaning additive that matches the water hardness; if not, issuing an alarm message or suggestion.

[0080] In the above scheme, if the laundry additives stored in the laundry additive dispensing device 100 do not have at least one laundry additive that matches the water hardness of the geographical area in which it is located, it means that the currently stored laundry additives are not suitable for clothing care with water at that water hardness, and an alarm message or suggestion should be issued to the user, prompting the user to replace or supplement the laundry additives.

[0081] In some embodiments of the present invention, in the above-mentioned step of obtaining the water hardness of the geographical area where the delivery device is located, those skilled in the art can adopt any feasible technical solution to enable the laundry additive delivery device 100 to obtain the geographical area where it is located, and then obtain the water hardness of the geographical area based on the geographical area.

[0082] An optional solution is that the cleaning additive delivery device 100 obtains the geographical area where it is located by self-positioning, and obtains the water hardness of the geographical area based on the geographical area.

[0083] In detail, the washing and care additive delivery device 100 includes a positioning module disposed thereon or in communication with the same. After the washing and care additive delivery device 100 is turned on, it can automatically and directly obtain the location information of its location through the positioning module. Among them, the positioning module can be a GPS positioning module, a Beidou positioning module, etc. When the washing and care additive delivery device 100 obtains the geographical area where it is located, the water hardness of the geographical area can be obtained.

[0084] Another optional solution is that the cleaning additive delivery device 100 obtains the geographical area where it is located by receiving external input, and obtains the water hardness of the geographical area based on the geographical area.

[0085] In detail, an information input device is provided on the washing and care additive delivery device 100, so that the washing and care additive delivery device 100 can obtain its location information with the help of the information input device. The information input device can be a touch screen, a keyboard operation device, etc., and can input location information at the street level. The user inputs the location information of the washing and care additive delivery device 100 into the washing and care additive delivery device 100 by operating the information input device. After obtaining the geographical area where the washing and care additive delivery device 100 is located, the water hardness of the geographical area can be obtained.

[0086] Another optional solution is to send the location information of the geographical area to the washing additive dispensing device 100 through a mobile terminal / server 106 that is communicatively connected to the washing additive dispensing device 100. The location information can be obtained by the mobile terminal itself, or it can be obtained by manual input by the user. The mobile terminal can be a mobile phone, a tablet computer, a laptop computer, etc. Of course, the location information can be obtained from the address of the server 106. In addition, those skilled in the art can also enable the washing additive dispensing device 100 to obtain location information from any feasible public service channel, such as a communication base station, as needed. The water hardness of the geographical area where the washing additive dispensing device 100 is located can be obtained.

[0087] The above-mentioned acquisition of the water hardness of the geographical area based on the geographical area includes retrieving the correspondence between multiple geographical areas and water hardness pre-stored in the cleaning additive delivery device 100 itself; or, retrieving the correspondence between multiple geographical areas and water hardness from the server 106.

[0088] In some other embodiments of the present invention, the above-mentioned step of obtaining the water hardness of the geographical area where the delivery device is located includes retrieving the water hardness stored in the clothing processing device 200 that is communicatively connected to the delivery device.

[0089] In detail, for some clothing processing devices 200, when the water hardness of the geographical area where the clothing processing device 200 is located is already stored on the device, the water hardness can be obtained after the detergent additive dispensing device 100 is connected to the clothing processing device 200 for communication.

[0090] In the above scheme, the following implementation method can be used to obtain the type of cleaning additive:

[0091] An optional implementation is to obtain the type of the laundry additive by detecting the laundry additive ingredients. Specifically, an additive ingredient detection unit capable of detecting the laundry additive ingredients is provided, such as a micro-spectrometer or a probe. It is understandable that the additive ingredient detection unit can be provided on the clothing processing device 200 itself, or on a laundry additive delivery device 100 that is relatively independent of the clothing processing device 200 itself.

[0092] Another optional implementation is to obtain the type of the cleaning additive by identifying the container label information of the cleaning additive. For example, the container of the cleaning additive purchased by the user is usually provided with a container label, and the container label is embedded with relevant information of the cleaning additive, such as purpose, pH value, dosage, etc. The container label can be a QR code, barcode, etc., and the relevant information of the cleaning additive can be obtained by scanning the container label information; it can also be an RFID electronic tag, etc., and the relevant information of the cleaning additive can be obtained by identifying it with an electronic identifier.

[0093] Another optional implementation is to receive information input by the user to obtain the type of the cleaning additive. Specifically, the user can read the information marked on the container label of the cleaning additive and manually input it or obtain and input the information online after shopping online, so as to determine whether the type of the cleaning additive matches the water hardness.

[0094] The above optional implementation modes may be implemented in combination or individually.

[0095] In some embodiments of the present invention, Figure 3 As shown, the control method of the above-mentioned washing and care additive delivery device 100 specifically includes the following steps:

[0096] S1, obtaining the water hardness of the geographical area where the deployment equipment is located;

[0097] S2, obtaining the type of cleaning additive;

[0098] S3, determining whether there is at least one cleaning additive that matches the water hardness; if so, executing S4, if not, issuing an alarm message or suggestion;

[0099] S4, adjusting the type of washing additives and / or the proportion of washing additives and / or the timing of washing additives in the washing program of the washing additive dispensing device 100 according to the water hardness and the type of washing additives;

[0100] S5, transmitting the adjusted washing and care program to the clothing processing device 200.

[0101] After receiving the washing and care program sent by the washing and care additive, the clothing processing device 200 performs the washing and care task according to the washing and care program.

[0102] like Figure 1 As shown, the washing additive dispensing device 100 of the present invention includes a first acquisition unit 101 , a processing unit 105 and a communication unit 104 .

[0103] The first acquisition unit 101 is used to acquire the water hardness of the geographical area where the delivery device is located. The first acquisition unit 101 may be a GPS positioning module or a Beidou positioning module.

[0104] The processing unit 105 is connected to the acquisition unit, receives the water hardness acquired by the acquisition unit, and adjusts the washing and care program of the washing and care additive delivery device 100 according to the water hardness. The processing unit 105 may pre-store a correspondence between multiple geographical areas and water hardness; when the processing unit 105 acquires geographical area information through the first acquisition unit 101, it may retrieve the water hardness matching the geographical area from its own database.

[0105] The communication unit 104 sends the washing and care program generated by the processing unit 105 to the clothing processing device 200. Of course, the communication unit 104 can also be connected to the mobile terminal or the server 106. Therefore, the processing unit 105 can also obtain relevant information about the water hardness from the mobile terminal or the server 106 or the clothing processing device 200 through the communication unit 104.

[0106] After obtaining the water hardness of the geographical area where the laundry additive is located, the processing unit 105 adjusts the laundry program according to the water hardness, and then sends the adjusted laundry program to the clothing processing device 200 for execution.

[0107] The cleaning additive delivery device 100 further includes a second acquisition unit 107 for acquiring the type of the cleaning additive.

[0108] Preferably, the second acquisition unit 107 includes a detergent additive component detector and / or an electronic identifier and / or an information reader.

[0109] In detail, adjusting the washing and care program of the washing and care additive delivery device 100 according to the water hardness includes: adjusting the type of washing and care additive delivered in the washing and care program and / or the delivery ratio of the washing and care additive and / or the delivery sequence of the washing and care additive.

[0110] Specifically, different laundry additives have different ingredients and uses, and users usually purchase corresponding types of laundry additives according to their family's needs. Moreover, with the development of chemical technology, there will be more and more types of laundry additives suitable for clothing care, and the requirements for using laundry additives to care for clothes are also getting higher and higher. Different water hardnesses need to match different types of laundry additives, different proportions of laundry additives, and different timings of laundry additives. The present invention adjusts the type of laundry additives and / or the proportion of laundry additives and / or the timing of laundry additives by water hardness, so as to better wash and care for clothes.

[0111] Preferably, the types of the washing and care additives include main detergents and auxiliary detergents, the main detergents include various types of detergents; auxiliary detergents are functionally divided into water softeners, bleaches, disinfectants, fragrance enhancers, etc.

[0112] Whether it is the main detergent or the auxiliary detergent, it can be divided into acidic detergent additives, neutral detergent additives and alkaline detergent additives from the perspective of acidity and alkalinity.

[0113] From the perspective of ingredients, main detergents can be divided into soap-based detergents and non-soap-based detergents.

[0114] Different types, ingredients, and pH levels of cleaning additives are suitable for different water hardnesses.

[0115] For example, soap-based detergents have sodium stearate as their main ingredient, which is produced through saponification of natural oils and fats. They have strong detergency and good biodegradability, are non-toxic to the human body, and do not pollute the environment. However, soap-based detergents easily undergo a replacement reaction with calcium and magnesium ions in hard water to form soap scum, which adheres to clothing, causing the washed clothing to become hardened, and forms dirt on washing utensils.

[0116] It can be seen that if the water hardness of the geographical area where the dispensing device is located is obtained as hard water, the automatic dispensing of soap-based detergent preset in the washing and care program can be adjusted to automatic dispensing of non-soap-based detergent.

[0117] It is also possible to adjust the automatic soap-based detergent dispensing preset in the washing program to automatically dispense soap-based detergent and water softener or fabric softener or laundry neutralizer at the same time.

[0118] Moreover, for areas with high hardness water, it is best to add water softener in each washing step, while softener and laundry neutralizer can be added in the final rinsing step. Therefore, when the preset automatic soap-based detergent in the washing program is adjusted to automatically add soap-based detergent and water softener or laundry neutralizer or softener at the same time, the timing of adding water softener or laundry neutralizer or softener should also be adjusted.

[0119] It is also possible, without adjusting the type of automatic soap-based detergent dispensed in the washing and care program, but adjusting the proportion of automatic soap-based detergent dispensed in the washing and care program.

[0120] Preferably, the hardness of the water in areas with softer water is 0.8g / L, that in areas with moderate water hardness is 1.0g / L, and that in areas with harder water hardness is 1.2g / L; for example, if the laundry additive dispensing device 100 is used in Nanjing, the first acquisition unit 101 obtains this location and uploads it to the processing unit 105, and the processing unit 105 automatically searches and matches Nanjing as an area with higher water hardness, and the dispensing ratio adopted is 1.2g / L, so when the clothing processing device 200 is running, for every 1L of water taken in, the laundry additive dispensing device 100 will dispense 1.2g of laundry additives.

[0121] In the above scheme, adjusting the proportion of the washing and care additives in the washing and care program is to adjust the proportion of the washing and care additives according to the water inlet flow rate. The washing and care additive delivery device 100 of the present invention delivers washing and care additives in a process of delivering a certain amount of washing and care additives for each certain amount of water inlet, and delivers the washing and care additives directly into the delivery waterway, so as to achieve mixing of the washing and care additives and water in the delivery waterway.

[0122] For example, when it is detected that the water hardness of the geographical area where the washing and care additive delivery device 100 is located is hard water, the delivery ratio of the detergent should be adjusted to match the hard water. In one embodiment, the delivery ratio of the detergent matching the hard water is 1.2g / L. That is, when the flow sensor detects that the water inlet flow rate reaches 1L, the liquid pump is controlled to extract 1.2g of detergent from the liquid storage box into the delivery water channel, which is a delivery interval. When the flow sensor detects that the water inlet flow rate reaches 1L again, the liquid pump is controlled to extract 1.2g of detergent from the liquid storage box into the delivery water channel again. This cycle repeats until the detergent extracted by the liquid pump reaches the delivery amount required in the washing and care program, and the delivery process ends, and the delivery water channel only supplies water to the clothing processing device 200.

[0123] In the above scheme, the detergent additives are added multiple times during the entire water intake process, so that the detergent additives are more easily evenly distributed in the water, thereby achieving a better washing effect. In addition, the addition chamber in the prior art is omitted, so that the product size of the detergent additive delivery device 100 of the present invention is smaller, which better meets the needs of users.

[0124] In a further solution, the control method of the cleaning additive dispensing device 100 also includes obtaining information about the cleaning additives; determining whether there is at least one cleaning additive that matches the water hardness; if not, issuing an alarm message or suggestion.

[0125] In the above scheme, if the laundry additives stored in the laundry additive dispensing device 100 do not have at least one laundry additive that matches the water hardness of the geographical area in which it is located, it means that the currently stored laundry additives are not suitable for clothing care with water at that water hardness, and an alarm message or suggestion should be issued to the user, prompting the user to replace or supplement the laundry additives.

[0126] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
