In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 to 3, the present invention provides an additive dispensing apparatus and a method for automatically purchasing a detergent additive thereof. As shown in fig. 1, the method for automatically purchasing a laundry additive comprises the steps of: determining that the residual quantity of the washing and protecting additive in the liquid storage container is insufficient; generating order information of the washing and protecting additives of the same type; the order information comprises the total net content of the washing and protecting additive, so that the total net content of the washing and protecting additive is smaller than or equal to the volume of a liquid storage container containing the washing and protecting additive.

Specifically, whether the residual amount of the washing and protecting additive in the liquid storage container of the additive feeding device 100 is insufficient is judged; if yes, generating order information for purchasing the same type of washing and protecting additive; the order information at least comprises the content information of the washing and protecting additive, so that the total net content of the washing and protecting additive in the order information can be matched with the volume of the liquid storage container.

In detail, the additive feeding device 100 is provided with an installation cavity for installing a liquid storage container in which a washing and protecting additive is stored, and a top-opening structure for opening a liquid outlet of the liquid storage container is arranged in the installation cavity. The liquid outlet of the liquid storage container is in a closed state under a normal state, namely before the liquid storage container is placed into the mounting cavity. When the liquid storage container is placed into the installation chamber, the ejection structure can automatically open the liquid outlet of the liquid storage container, so that the dispensing mechanism 102 of the additive dispensing device 100 can suck the washing and protecting additive from the liquid storage container.

When the washing and protecting additive in the liquid storage container is used up, the user can take the liquid storage container out of the installation cavity, and the liquid storage container is placed into the installation cavity after the washing and protecting additive is automatically added.

It should be noted that the liquid storage container described in the present invention is a recyclable liquid storage container, and a user may purchase a replacement package of the washing and caring additive, and load the washing and caring additive in the replacement package into the liquid storage container.

The method for automatically purchasing the washing and protecting additive by the additive feeding device 100 can automatically purchase the washing and protecting additive singly when the residual quantity of the washing and protecting additive in the liquid storage container is insufficient, and the total net content of the purchased washing and protecting additive can be matched with the volume of the liquid storage container. Therefore, when the washing and protecting additive in the liquid storage container is used up, the user can completely add the purchased washing and protecting additive into the liquid storage container, the time for purchasing the washing and protecting additive is saved for the user, the purchasing operation is simplified, the user can not need to additionally store the washing and protecting additive, the storage space is saved, the user can use the washing and protecting additive with shorter delivery time, and the performance of the washing and protecting additive is ensured.

In a further aspect, the total net wash additive content in the order message is formed by multiplying the net wash additive content in a single package by the number of units placed.

In detail, the total net content of the washing and protecting additive is matched according to the volume of the liquid storage container when order information is generated, so that the situation that the total net content of the purchased washing and protecting additive is larger than the volume of the liquid storage container is avoided, the purchased washing and protecting additive cannot be completely added into the liquid storage container, the storage space of a user's home still needs to be occupied, and if the residual washing and protecting additive is thrown away, waste is caused.

For example, if the volume of the liquid storage container of the additive dispensing device 100 containing the detergent additive is 500ml, the total net content of the detergent additive in the automatically generated order information may be just 500ml, or 400ml, etc.

Also, one 500ml piece of the lotion additive may be automatically purchased, or two 250ml pieces of the lotion additive may be automatically purchased, or three 150ml pieces of the lotion additive may be automatically purchased.

In a further scheme, the additive feeding device 100 memorizes the order information of purchasing the washing and caring additive at the last time; and when the residual quantity of the washing and protecting additive in the liquid storage container is determined to be insufficient, purchasing the washing and protecting additive in the last order information when the order information is generated.

In detail, the additive dispensing device 100 has a memory function, and the additive dispensing device 100 automatically memorizes the order information of the additive for automatically placing an order and purchasing a washing care additive. And when the residual quantity of the washing and protecting additive in the liquid storage container is determined to be insufficient, calling the commodity information of the washing and protecting additive in the order information of the washing and protecting additive purchased last time when the order information is generated, and directly ordering the commodity.

It can be understood that the washing and caring additive purchased last time is the washing and caring additive currently used by the user, and the scheme can directly call the commodity information of the washing and caring additive and generate order information, so that the step of generating the order can be simplified, and the response speed can be improved.

In a further aspect, the order information of the washing and caring additive purchased last time memorized in the additive dispensing device 100 includes concentration information, brand information, and net content information of the washing and caring additive; and when the sales information of the washing and protecting additive in the last order information shows that no goods exist, matching other goods washing and protecting additives according to the sequence of the net content information, the brand information and the concentration information.

For example, if the commercial information of the laundry additive in the order information of the last purchase of the laundry additive is 500ml of the anionic liquid detergent of brand a and 15% concentration, the commercial information should be selected for purchase when the remaining amount in the liquid storage container is insufficient and the order information is generated.

If the sales information of the commodity shows no goods, other commodities of the anionic liquid detergent with the net content of 15% and the brand A meeting the volume of the liquid storage container should be matched when the commodities of other washing and protecting additives are matched.

If the brand A with the net content capable of meeting the volume of the liquid storage container and other commodities of the anionic liquid detergent with the concentration of 15% are not screened, the brands with the net content capable of meeting the volume of the liquid storage container and other commodities of the anionic liquid detergent with the concentration of 15% are further matched.

If other brands of anionic liquid detergent with the net content capable of meeting the volume of the liquid storage container and the concentration of the anionic liquid detergent is not screened, other brands of anionic liquid detergent with the net content capable of meeting the volume of the liquid storage container and other commodities of anionic liquid detergent with other concentration information are further matched.

If the commodities meeting the conditions are not screened yet, a reminding signal is sent to the user to prompt the user to purchase the washing and protecting additive by himself so as to prevent the situation that the washing and protecting additive is used up and is not supplemented and normal use of the user is influenced.

In the scheme, the concentration mainly refers to the content of active matters in the washing and protecting additive, and the concentration information of the washing and protecting additive is an important parameter capable of realizing the function of nursing clothes. Generally, for laundry detergents, the effective active content is high, and the detergency is stronger; for the laundry disinfectant, the content of the parachlorometaxylenol should be controlled within a certain range, and the concentration of other types of washing and protecting additives should meet certain standards.

In addition, the additive feeding device can also set a feeding proportion matched with the concentration information.

Therefore, the concentration information is fully considered when the order information of the washing and caring additive is automatically generated, more intuitive and applicable commodities can be automatically purchased for users by placing orders, the users can be better served, and the use experience of the users is improved.

In some embodiments of the present invention, the order information further includes concentration information of the detergent additive, where the concentration information is information that the additive dispensing device 100 can unlock the dispensing mechanism 102 of the additive dispensing device 100 after acquiring the concentration information of the detergent additive.

Specifically, the additive feeding device 100 is further provided with a concentration detection unit 101 for detecting the concentration of the detergent additive in the liquid storage container, the concentration detection unit 101 is connected with a main control board 105 of the additive feeding device 100, and transmits the detected concentration of the detergent additive to the main control board 105, so that the main control board 105 controls the locking or unlocking state of the feeding mechanism 102 according to the concentration of the detergent additive.

In detail, a concentration range of the detergent additive contained in the liquid storage container is preset in the main control board 105, and when the concentration of the detergent additive in the liquid storage container is within the preset concentration range, the releasing state of the releasing mechanism 102 is controlled to be unlocked; and when the concentration of the washing and protecting additive in the liquid storage container is not in the preset concentration range, controlling the feeding state of the feeding mechanism 102 to be locked.

In other words, if the concentration information of the laundry additive cannot satisfy the dosing criteria of the additive dosing device 100, the laundry additive should not be dosed into the laundry treatment device 200, so as not to cause problems such as too large dosing accuracy difference of the additive dosing device 100 or blockage of the dosing port.

The detection principle and mechanism of the concentration detection unit 101 for detecting the concentration of the detergent additive in the above scheme are common design means in the field, and any concentration detection unit 101 capable of realizing the above functions can be used by the additive feeding device 100 of the present invention, and the present invention is not described herein again.

In a further aspect, the dispensing mechanism 102 may be a dispensing pump or a venturi, and the main control board 105 of the additive dispensing device 100 may control to turn on or off the dispensing pump or the venturi. For example, in one scheme, a control switch may be disposed between the dispensing pump or the venturi tube and the power supply, and when the main control board 105 determines that the concentration information of the washing additives in the liquid storage container does not meet the preset requirement, the main control board controls the control switch to be turned off, so that the dispensing pump or the venturi tube is in a power-off locking state and cannot dispense the washing additives; when the concentration information of the washing and protecting additive in the liquid storage container is judged to meet the preset requirement, the control switch is controlled to be switched on, so that the throwing pump or the Venturi tube is in a power-on unlocking state, and the throwing instruction can be normally executed.

Or in another scheme, a self-locking mechanism may be arranged on the dispensing pump or the venturi tube, and when the main control board 105 determines that the concentration information of the washing and caring additive in the liquid storage container does not meet the preset requirement, the self-locking mechanism is controlled to lock the dispensing pump or the venturi tube, so that the dispensing mechanism 102 is in a locked state and cannot dispense the washing and caring additive; when judging the concentration information that the additive was protected in the stock solution container washing and when meeting predetermined demand, then control self-locking mechanism will throw in pump or venturi unblock, makes it can normal execution throw in the instruction to throw in pump or venturi.

In some embodiments of the present invention, the additive dispensing device 100 is provided with a plurality of mounting chambers for mounting liquid reservoirs of different types of wash additives, and each mounting chamber is in one-to-one correspondence with the matching mounting manner between the liquid reservoirs in the mounting chamber.

When the residual quantity of the washing and protecting additive in one of the liquid storage containers is insufficient, the residual quantities of the washing and protecting additives in the other liquid storage containers are detected, whether the residual quantity of the washing and protecting additive in at least one liquid storage container is about to be insufficient or not is judged, and if yes, purchase information of the washing and protecting additive of which the type is the same as that of the washing and protecting additive in the liquid storage container is further included in the order information.

In detail, the washing and protecting additive plays an important role in the washing and protecting process of clothes, the feeding requirement of the washing and protecting of the clothes on the additive is higher and higher, and the types of the washing and protecting additive are more and more along with the development of chemical technology. Therefore, a plurality of mounting chambers are also provided in the additive delivery device 100 for placing different functional laundry additives.

For example, the types of wash-care additives include main washes, including various types of detergents, and builders; builders are functionally classified as softeners, bleaches, disinfectants, odorants, and the like.

Because the washing and protecting additives with different functions have different states, different use occasions, different use frequencies, different input amounts and the like, the matching installation modes between the liquid storage containers for containing the washing and protecting additives with different functions and the installation cavity are different.

Therefore, when the fact that the residual quantity of the laundry care additive in one of the liquid storage containers is insufficient is detected, the purchased laundry care additive is automatically purchased separately and is of the same type as the laundry care additive, and the situation that the type of the purchased laundry care additive is different from that of the laundry care additive which is about to be used up, so that the washing and care requirements of a user on clothes are influenced is avoided.

Further, as shown in fig. 2, when it is detected that the remaining amount of the detergent additive in one of the liquid storage containers is insufficient, it should be further detected whether the remaining amount of the detergent additive in the other liquid storage containers is within a set range, and if so, it indicates that the remaining amount of the other types of detergent additives is also about to be insufficient.

For the above scheme, judging whether the remaining amount of the detergent additive in the liquid storage container of the additive dispensing device 100 is insufficient, the present invention may adopt the following scheme:

optionally, recording the amount of the washing and protecting additive in the liquid storage container each time, and superposing the amount of the washing and protecting additive each time; and when the numerical value obtained after the superposition of the feeding amount of the liquid storage container every time reaches a preset value, determining that the residual amount of the washing and protecting additive in the liquid storage container is insufficient.

In detail, the main control board 105 of the additive feeding device 100 is provided with a metering program, when a liquid storage container of the washing and caring additive is replaced, the additive feeding device 100 can obtain the total volume of the washing and caring additive in the liquid storage container by identifying an identification tag on the liquid storage container, and the fed amount of the washing and caring additive in the liquid storage container is synchronously cleared.

During the use process, the additive feeding device 100 records the feeding amount each time when the washing and caring additive in the liquid storage container is fed each time, and superposes the feeding amounts each time. When the value obtained after the addition of each dosage reaches a preset value, for example 90% of the total volume, it is determined that the residual amount of the detergent additive in the liquid storage container is insufficient, and the detergent additive should be purchased singly.

Optionally, the adding times of the washing and protecting additive in the liquid storage container are recorded, and the adding times are superposed; and when the numerical value obtained after the adding times of the liquid storage container are superposed reaches a preset value, determining that the surplus of the washing and protecting additive in the liquid storage container is insufficient.

Specifically, the additive dispensing device 100 according to the present embodiment further includes a water discharge passage 103, as shown in fig. 3. A plurality of installation cavities for installing liquid storage containers for containing different types of washing and protecting additives, and a throwing pipeline is arranged between each installation cavity and the water throwing and discharging channel 103. The two ends of the throwing pipeline are respectively communicated with the liquid storage container and the throwing water channel 103, and the throwing mechanism 102, such as a throwing pump or a venturi tube, is arranged on the throwing pipeline. The main control panel 105 controls the dosing mechanism 102 to dose the rinse and care additive into the water dosing waterways 103. The additive dispensing device 100 further comprises a flow sensor for detecting the water inflow of the laundry treating device 200, the flow sensor being disposed on the dispensing water path 103.

When the clothes treating device is used, the water inlet end of the water throwing-off water channel 103 is connected with a tap water connector, and the water outlet end of the water throwing-off water channel 103 is connected to the water inlet of the clothes treating device 200.

When the automatic laundry additive feeding process in the laundry program is operated, the water inlet valve of the laundry treatment apparatus 200 is opened, and the outlet water of the tap water connector passes through the water feeding water path 103 of the laundry additive feeding apparatus 100, and then enters the laundry treatment apparatus 200 from the water inlet of the laundry treatment apparatus 200. The feeding mechanism 102 feeds the laundry additive in the liquid storage container into the water feeding channel 103, so that the laundry additive enters the laundry treatment apparatus 200 along with the tap water in the water feeding channel 103.

In the process of adding the washing and protecting additive by the additive adding device 100 in the embodiment, a certain amount of washing and protecting additive is added every certain amount of water, the washing and protecting additive is directly added into the water adding and discharging water channel 103, and the mixing of the washing and protecting additive and the water is realized in the water adding and discharging water channel 103.

For the additive dispensing device 100 having the above dispensing manner, a metering program is provided in the main control board 105 of the additive dispensing device 100, when a storage container of the wash-care additive is replaced, the additive dispensing device 100 can obtain the maximum number of times that the wash-care additive in the storage container can be allowed to be dispensed by identifying an identification tag on the storage container, and the number of times that the wash-care additive in the storage container is dispensed is synchronously cleared. The additive feeding device 100 records the feeding times and superposes the feeding times when the washing and protecting additive in the liquid storage container is fed each time. When the superposed number of times of dosing reaches a preset value, for example 90% of the maximum number of times, it is determined that the residual amount of the detergent additive in the liquid storage container is insufficient, and the detergent additive should be purchased on a single basis.

According to the scheme of setting the metering program in the main control board, the metering of the balance of the detergent additive can be realized on the basis of not additionally setting a device for detecting the balance of the detergent additive, the structure of the additive feeding device 100 can be simplified, and the cost of the additive feeding device 100 can be reduced.

In the above scheme, the criterion for determining whether the residual amount of the washing and protecting additive in the liquid storage container is about to be insufficient is a set value which is adjusted downward based on the criterion for determining whether the residual amount of the washing and protecting additive in the liquid storage container is insufficient.

For example, when the criterion for determining whether the remaining amount of the cleaning additive in the liquid storage container is insufficient is that the value obtained by superposing each amount of the cleaning additive in the liquid storage container reaches 90% of the total volume, the criterion for determining whether the remaining amount of the cleaning additive in the liquid storage container is about to be insufficient is that the value obtained by superposing each amount of the cleaning additive in the liquid storage container reaches 80% of the total volume.

Optionally, a weight detection unit is arranged at a position of the additive feeding device 100, where the position is used for installing the liquid storage container, and the weight of the washing and protecting additive in the liquid storage container is detected by the weight detection unit; and when the weight of the washing and protecting additive in the liquid storage container is lower than a preset value, determining that the balance of the washing and protecting additive in the liquid storage container is insufficient.

Optionally, the additive feeding device 100 is provided with a liquid level detection unit for detecting the liquid level of the washing and protecting additive in the liquid storage container, and the liquid level of the washing and protecting additive in the liquid storage container is detected by the liquid level detection unit; and when the liquid level of the washing and protecting additive in the liquid storage container is lower than a preset value, determining that the residual quantity of the washing and protecting additive in the liquid storage container is insufficient.

Utilize weight detecting element or liquid level detecting element to detect the surplus of washing and protecting the additive among the above-mentioned scheme, it is high to detect the precision, can accurate control wash the in service behavior of protecting the additive, makes the user family needn't stocked and protects the additive, realizes good replenishment mechanism, promotes user experience.

In the scheme, the criterion for judging whether the residual quantity of the washing and protecting additive in the liquid storage container is about to be insufficient is to float a set value on the basis of the criterion for judging whether the residual quantity of the washing and protecting additive in the liquid storage container is insufficient.

For example, when the criterion for determining whether the remaining amount of the lotion additive in the reservoir is insufficient is when the weight of the lotion additive in the reservoir is less than 10% of the total weight, then the criterion for determining whether the remaining amount of the lotion additive in the reservoir is about to be insufficient is when the weight of the lotion additive in the reservoir is less than 20% of the total weight.

In a further scheme, the generated order information for purchasing the washing and caring additive is sent to the App of the intelligent terminal 300 of the user by the communication unit 104 of the additive feeding device 100, and if the App for order payment in the intelligent terminal 300 of the user sets the small-amount password-free payment, the order can be directly placed for purchase when the amount of the order does not exceed the amount of the small-amount password-free payment set by the user, and the user does not need to wait for the confirmation of the order. When the amount of the order exceeds the small amount of the password-free payment set by the user, the user needs to wait for the order to be placed for purchase after confirming the payment.

The present invention also provides an additive dispensing device 100 for implementing the above-described method for automatically purchasing a laundry additive. The additive dispensing device 100 is installed outside the laundry treating device 200; alternatively, the additive dispensing device 100 and the laundry treating device 200 are two independent devices.

In the present invention, the additive feeding device 100 and the laundry treating device 200 have independent control systems, respectively, and the additive feeding device 100 is disposed between a tap water connector and a water inlet valve of the laundry treating device 200, and the laundry treating device 200 includes, but is not limited to, a pulsator washing machine, a drum washing machine, and a washing and drying machine.

In one arrangement, the additive dispensing device 100 may be mounted outside the laundry treating device 200, i.e. the additive dispensing device 100 is mounted on the laundry treating device 200 and located outside the laundry treating device 200, e.g. the additive dispensing device 100 may be fixedly mounted on an outer side wall of a cabinet of the laundry treating device 200.

Or, in another scheme, the additive feeding device 100 and the laundry treatment device 200 are two sets of devices independent from each other, and the additive feeding device 100 and the laundry treatment device 200 are not in an assembly connection relationship and are two sets of devices independent from each other, so that the positions where the additive feeding device 100 is disposed are relatively unlimited, and as long as the water inlet pipeline communication between the additive feeding device 100 and the laundry treatment device 200 and the tap water connector can be realized, the additive can be fed into the washing machine along with the water inlet of the water inlet pipeline.

Although the present invention has been described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the present invention.
