Specific Embodiments

[0037] To make the objectives, 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 with reference to the accompanying 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.

[0038] In the description of the present invention, it should be noted that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. are based on the orientation or positional relationships shown in the 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 orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention.

[0039] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, 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 directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] As Figure 1 and Figure 2 shown, a dosing device according to the present invention, the dosing device includes a dispenser box 1.

[0041] The dispenser box 1 has a receiving cavity 11 for holding detergent, and is provided with a water outlet 12 communicating with the receiving cavity 11.

[0042] The detergent is a common liquid substance such as laundry detergent, fabric softener, disinfectant, bleach, etc. for treating clothes.

[0043] The dispenser box 1 is slidably arranged on the washing machine. The top part of the dispenser box 1 is open, communicating with the accommodating cavity 11. The opening can be used for water inlet, serving as a water inlet, and at the same time can also be used as a feeding port for adding detergent. In addition, the water inlet and the feeding port can also be separately arranged on the dispenser box 1. Of course, the dispenser box 1 can also be arranged to be fixed on the washing machine.

[0044] After the user adds detergent into the dispenser box 1, the washing machine intakes water. The water enters the accommodating cavity 11 of the dispenser box 1 from the water inlet. After the water mixes with the detergent, it flows out from the water outlet 12 and enters the washing tub of the washing machine. The water continuously enters the accommodating cavity 11 from the water inlet, and can flush all the detergent in the accommodating cavity 11 into the washing tub. The washing tub works, and the water mixed with the detergent can clean the clothes in the washing tub.

[0045] In the prior art, before the washing machine washes, the user needs to add detergent into the dispenser box 1 first. During the washing process, the washing machine intakes water multiple times to flush all the detergent in the accommodating cavity 11 into the washing tub. Therefore, the user needs to add detergent before each washing of the washing machine, and the single dosing amount of the dosing device is the amount of detergent added by the user. Whether the user adds detergent manually or automatically, it is easy to have too much detergent in the dispenser box 1, resulting in the phenomenon of overflowing washing foam and incomplete rinsing, causing complaints from users.

[0046] The dosing device of the present invention further includes a liquid storage device 3.

[0047] The water outlet 12 can be arranged to be openable and closable.

[0048] The liquid storage device 3 has a liquid storage cavity, and the liquid storage cavity is communicably arranged with the accommodating cavity 11 for sucking the detergent in the accommodating cavity 11 into the liquid storage cavity or discharging the detergent in the liquid storage cavity back into the accommodating cavity 11.

[0049] In the above solution, the liquid storage device 3 is provided. When the liquid storage device 3 works, it can suck the detergent in the accommodating cavity 11 into the liquid storage cavity or discharge the detergent in the liquid storage cavity back into the accommodating cavity 11, so as to increase or decrease the detergent in the accommodating cavity 11, control the single dosing amount of the dosing device, prevent the washing foam from overflowing, and thoroughly rinse the clothes, which is convenient to use.

[0050] Specifically, different weights of clothes require different amounts of detergent. An appropriate amount of detergent can not only prevent the washing foam from overflowing, but also ensure thorough rinsing of the clothes. Therefore, different clothes weights correspond to different optimal dosages of detergent to be dispensed.

[0051] When the liquid storage device 3 operates, a pressure difference will be formed inside and outside the liquid storage chamber. If there is too much detergent in the accommodation chamber 11, the liquid storage device 3 will suck the excess detergent into the liquid storage chamber for storage, reducing the one-time dispensing amount of the controllable dispensing device. At this time, water enters the dispenser box 1, and the water mixes with the remaining detergent in the accommodation chamber 11 to achieve the best washing effect on the clothes, which can prevent the washing foam from overflowing and ensure thorough rinsing of the clothes, facilitating use. If the amount of detergent in the accommodation chamber 11 is small and there is detergent stored in the liquid storage device 3, the liquid storage device 3 will discharge the detergent in the liquid storage chamber back into the accommodation chamber 11.

[0052] It should be noted that the amount of detergent in the accommodation chamber 11 here does not include the detergent stored in the liquid storage device 3.

[0053] The water outlet 12 can be opened or closed according to the actual situation. Before water enters the dispenser box 1, the water outlet 12 is closed to prevent the added detergent from directly overflowing from the water outlet 12, resulting in inaccurate judgment of the amount of detergent in the accommodation chamber 11. Before water enters, first control the liquid storage device 3 to suck part of the detergent in the accommodation chamber 11. After the remaining detergent in the accommodation chamber 11 reaches the optimal dosage of detergent, the water outlet 12 is opened, and then water enters.

[0054] Preferably, a solenoid valve is provided at the water outlet 12 for controlling the opening and closing of the water outlet 12.

[0055] The liquid storage device 3 is arranged in the dispenser box 1 and includes a sleeve 31 and a moving member 32. The sleeve 31 has the liquid storage chamber, and the moving member 32 is movably arranged in the liquid storage chamber, moving inward or outward relative to the liquid storage chamber to form a pressure difference inside and outside the liquid storage chamber.

[0056] In the above solution, the moving member 32 moves inward or outward relative to the liquid storage chamber, which can increase or decrease the pressure in the liquid storage chamber, form a pressure difference inside and outside the liquid storage chamber, discharge the detergent in the liquid storage chamber, or suck the detergent in the accommodation chamber 11, facilitating the control of the amount of detergent in the accommodation chamber 11.

[0057] Specifically, when the moving member 32 moves inward relative to the liquid storage cavity, the volume of the sealed liquid storage cavity decreases, and the internal pressure increases, causing the detergent in the liquid storage cavity to be discharged; when the moving member 32 moves outward relative to the liquid storage cavity, the volume of the sealed liquid storage cavity increases, and the internal pressure decreases, causing the detergent in the accommodation cavity 11 to be sucked in.

[0058] The liquid storage device 3 is disposed inside or outside the dispenser box 1.

[0059] Preferably, the liquid storage device 3 is disposed inside the accommodation cavity 11.

[0060] The dispenser box 1 has a box-like structure.

[0061] In one embodiment of the present invention, the liquid storage device 3 is disposed outside the dispenser box 1.

[0062] Specifically, when the liquid storage device 3 is disposed outside the dispenser box 1 and the liquid storage device 3 is connected to the dispenser box 1 or the box body of the washing machine, the overall installation space of the dispensing device will be increased. Also, since the liquid storage cavity of the liquid storage device 3 is communicated with the accommodation cavity 11, a communication pipeline needs to be provided between the liquid storage cavity and the accommodation cavity 11, which will make the structure of the dispensing device more complex and increase the processing cost.

[0063] In another embodiment of the present invention, the dispenser box 1 is provided with a hollow chamber spaced apart from the accommodation cavity 11, and the liquid storage device 3 is disposed in the hollow chamber.

[0064] Specifically, although disposing the liquid storage device 3 in the hollow chamber can reduce the installation space of the dispensing device, setting two independent chambers in the dispenser box 1 and communicating the liquid storage cavity with the accommodation cavity 11 makes the processing difficult and inconvenient to use.

[0065] In yet another embodiment of the present invention, the liquid storage device 3 is disposed inside the accommodation cavity 11.

[0066] Specifically, the space inside the accommodation cavity 11 is relatively large. Disposing the liquid storage device 3 inside the accommodation cavity 11 is convenient for installation, causes less modification to the dispenser box 1, reduces the processing difficulty, and can also reduce the installation space of the dispensing device, making it convenient to use.

[0067] Preferably, the dispensing device further includes a liquid level detector 2 and a controller. The liquid level detector 2 is disposed inside the dispenser box 1 for detecting the liquid level inside the accommodation cavity 11; the controller is electrically connected to the liquid level detector 2 and the liquid storage device 3 respectively, and is used for receiving the detected liquid level and determining whether it exceeds a threshold value to control the corresponding operation of the liquid storage device 3.

[0068] Specifically, when water enters the dispenser box 1, the water flow may impact against the inner wall of the accommodating cavity 11, causing the water flow to splash. By disposing one end of the liquid storage device 3 within the installation cavity 41, it can play a certain role in waterproofing. The other end of the liquid storage device 3 penetrates through the bottom wall of the installation cavity 41, facilitating the liquid storage device 3 to absorb the detergent.

[0069] The liquid level detector 2 can be set as a liquid level sensor or other devices with liquid level detection functions.

[0070] The liquid level detector 2 detects the liquid level of the detergent within the accommodating cavity 11. The controller receives the detected liquid level signal and compares the actual detergent dosage with the optimal detergent dosage corresponding to the weight of the laundry. If the actual detergent dosage is more than the optimal detergent dosage, it controls the liquid storage device 3 to suck the excess detergent within the accommodating cavity 11 into the liquid storage cavity for storage; if the actual detergent dosage is less than the optimal detergent dosage, it controls the liquid storage device 3 to discharge the detergent within the liquid storage cavity back into the accommodating cavity 11, thereby controlling the single dosage of the dispensing device. The remaining detergent amount within the accommodating cavity 11 is the optimal detergent dosage corresponding to the weight of the laundry. The threshold refers to the optimal detergent dosage corresponding to the weight of the laundry.

[0071] It should be noted that the actual detergent dosage refers to the amount of detergent within the accommodating cavity 11. The liquid level detector 2 detects the liquid level of the detergent within the accommodating cavity 11, excluding the detergent stored within the liquid storage device 3. Only when the liquid storage device 3 discharges the detergent within the liquid storage cavity back into the accommodating cavity 11 can it be detected by the liquid level detector 2.

[0072] The controller can be set separately or integrated into the main controller or other controllers within the washing machine.

[0073] The top wall of the accommodating cavity 11 is partially open, and a detachable cover plate 4 is provided within the opening. The liquid storage device 3 is disposed on the cover plate 4 and is disposed within the accommodating cavity 11.

[0074] In the above solution, the liquid storage device 3 is disposed on the cover plate 4 and the cover plate 4 is detachably provided. As a whole, it can be used as a single component. Users can choose whether to install it on the dispenser box 1, which has stronger applicability, is convenient for realizing assembly line operations, and is convenient for the overall assembly of the washing machine.

[0075] Specifically, the liquid storage device 3 is arranged on the cover plate 4 and the cover plate 4 is detachable. When the liquid storage cavity in the liquid storage device 3 is full of detergent and cannot be absorbed further, the cover plate 4 can be removed to collect the detergent in the liquid storage device 3 for subsequent use; it can also be arranged that when the liquid storage cavity in the liquid storage device 3 stores a certain amount of detergent, it is directly added to the containing cavity 11 before washing, and the user does not need to add detergent.

[0076] The liquid storage device 3 and the cover plate 4 are detachably arranged as a whole, and the whole can be used as a separate component. The user can choose whether to install it on the dispenser box 1. The arrangement method is more flexible, the user has greater choices, and the overall applicability is stronger. The whole is used as a component, which is convenient for assembly line operation, the overall assembly of the washing machine, and the use.

[0077] In addition, the cover plate 4 may also be configured to be rotatably connected to the dispenser box 1 .

[0078] The top wall of the accommodating cavity 11 is provided with a water inlet, and the liquid storage device 3 is arranged on the top wall of the accommodating cavity 11 .

[0079] The liquid storage device 3 further includes a driving unit 33 , which is in transmission connection with the sleeve 31 or the moving member 32 , and drives the sleeve 31 or the moving member 32 to move.

[0080] Specifically, the space between the bottom wall of the sleeve 31 and the moving member 32 is the liquid storage chamber.

[0081] The sleeve 31 and the moving member 32 move relative to each other. The driving unit 33 is in driving connection with the sleeve 31 or the moving member 32, and the moving member 32 or the sleeve 31 is fixedly arranged; when the driving unit 33 works, the sleeve 31 or the moving member 32 moves, and the sleeve 31 and the moving member 32 move relative to each other, so that the liquid storage device 3 can absorb or discharge detergent, and the detergent in the accommodating chamber 11 can be reduced or increased, thereby controlling the one-time dispensing amount of the dispensing device, which is convenient for use.

[0082] One end of the liquid storage cavity is provided with a liquid inlet, which is arranged toward the bottom wall of the accommodating cavity 11, and the other end is open.

[0083] The moving member 32 includes a piston 321 and a piston rod 322 which are connected to each other. The piston 321 is slidably sealed and disposed in the liquid storage cavity, and the piston rod 322 is disposed through the opening.

[0084] The cover plate 4 has a mounting cavity 41 therein.

[0085] One embodiment of the present invention, as Figure 1As shown, the driving unit 33 is arranged in the installation cavity 41. An installation hole is provided on the bottom wall of the installation cavity 41. The piston rod 322 passes through the installation hole. One end of the piston rod 322 is in transmission connection with the driving unit 33 and is movably arranged in the installation cavity 41. At least part of the sleeve 31 is fixedly arranged outside the installation cavity 41 and seals the installation hole.

[0086] Specifically, one end of the sleeve 31 is fixedly connected to the inner wall of the installation cavity 41 or the inner wall of the installation hole, and can seal the installation hole. The other end of the sleeve 31 is arranged outside the installation cavity 41; it can also be arranged that the whole sleeve 31 is located outside the installation cavity 41. One end of the sleeve 31 covers outside the installation hole and seals the installation hole; the electronic components related to the liquid storage device 3 are arranged in the installation cavity 41. The sleeve 31 seals the installation hole, which is equivalent to the installation cavity 41 being hermetically arranged, conducive to improving the waterproof performance, avoiding damage to the electronic components, and facilitating use.

[0087] The driving unit 33 can be set as motor drive. The motor is in transmission connection with one end of the piston rod 322. The sleeve 31 vertically penetrates the bottom wall of the installation cavity 41 and is fixedly connected. The liquid inlet of the sleeve 31 is arranged close to the bottom wall of the accommodation cavity 11.

[0088] When the motor rotates forward, the piston rod 322 moves upward accordingly, that is, the piston 321 moves upward. The interval between the piston 321 and the bottom wall of the sleeve 31 increases, and the detergent in the accommodation cavity 11 can be sucked and stored in the liquid storage cavity; when the motor rotates reversely, the piston rod 322 moves downward accordingly, that is, the piston 321 moves downward. The interval between the piston 321 and the bottom wall of the sleeve 31 decreases. If there is detergent in the liquid storage cavity, the detergent can be discharged into the accommodation cavity 11 to increase the detergent in the accommodation cavity 11.

[0089] Preferably, the driving unit 33 and the sleeve 31 are both vertically extended and arranged in the installation cavity 41. The driving unit 33 includes a motor and a transmission member. The motor is fixed in the installation cavity 41. The driving shaft of the motor is vertically extended and connected with a transmission member. The transmission member is connected with the piston rod 322.

[0090] The transmission member includes a screw rod and a nut connected by threads. The screw rod is vertically extended. The screw rod and the nut are correspondingly connected to the driving shaft of the motor and the piston rod 322 respectively.

[0091] A vertically extending stopper is provided in the installation cavity 41 and connected to the nut or the piston rod 322. The stopper includes a slide groove and a slider provided on the inner wall of the installation cavity 41, the slider is slidably connected to the slide groove, and the slider is connected to the nut or the piston rod 322.

[0092] The slide groove is vertically extended, and the slider slides up and down in the slide groove. Therefore, when the slider is connected to the nut or the piston rod 322, it can limit the nut so that it cannot rotate but can only move up and down.

[0093] Another embodiment of the present invention, as Figure 2 As shown, the liquid storage device 3 further includes a telescopic unit 34 , one end of which is connected to the top wall of the accommodating cavity 11 , and the other end of which can be telescopically arranged up and down and is connected to the sleeve 31 .

[0094] One end of the driving unit 33 is disposed at the other end of the telescopic unit 34 , and the other end of the driving unit 33 is transmission-connected to the moving member 32 .

[0095] One end of the telescopic unit 34 is connected to the top wall of the installation cavity 41 , and the other end thereof is disposed through the bottom wall of the installation cavity 41 .

[0096] Specifically, the telescopic unit 34 can be configured as an electric telescopic rod, which is vertically extended, one end of which is connected to the top wall of the installation cavity 41, and the other end of which passes through the bottom wall of the installation cavity 41. The driving unit 33 is fixedly disposed at the other end of the telescopic unit 34, and the sleeve 31 is also fixedly disposed at the other end of the telescopic unit 34. The driving unit 33 is transmission-connected to the piston rod 322, and the configuration is the same as that of the previous embodiment.

[0097] The driving unit 33 and the sleeve 31 are both arranged on the telescopic unit 34. When the telescopic unit 34 is in operation, its own length can be adjusted, and then the height of the sleeve 31 can be adjusted, so that the distance between the sleeve 31 and the bottom wall of the accommodating chamber 11 can be adjusted. When the detergent in the accommodating chamber 11 needs to be sucked, the sleeve 31 is moved close to the bottom wall of the accommodating chamber 11, the driving unit 33 is in operation, and the piston rod 322 moves upward, so that the liquid storage device 3 can suck the detergent. After the sucking is completed, the telescopic unit 34 shortens its own length and the height of the sleeve 31 can be increased.

[0098] The present invention also provides a washing machine, comprising any one of the above-mentioned placing devices.

[0099] Specifically, after the dosing device is installed on the washing machine, even if the amount of detergent in the dispenser box 1 is excessive, the liquid storage device 3 can suck the detergent in the accommodation chamber 11, so that the one-time dosing amount of the dosing device can be controlled, and further the amount of detergent dosed each time the washing machine washes can be controlled, avoiding the washing foam from overflowing and ensuring thorough rinsing of the clothes.

[0100] As Figure 3 and Figure 4 shown, the present invention also provides a control method for the washing machine as described above. The control method includes the following steps:

[0101] Obtain the weight G1 of the clothes, the optimal dosing amount A1 of the detergent corresponding thereto, and the actual dosing amount A of the detergent. Determine if A > A1. If so, control the liquid storage device to suck the excess detergent.

[0102] Specifically, there are various ways to obtain the weight G1 of the clothes. One way is to use a weight sensor, and the other way is to use a dedicated motor and hardware circuit to cooperate to achieve the automatic weighing function.

[0103] When in use, the user puts the clothes into the washing tub and adds detergent to the dosing device; then weighs the clothes, detects the liquid level of the detergent in the accommodation chamber, and obtains the weight G1 of the clothes and the actual dosing amount A of the detergent.

[0104] Calculate the optimal dosing amount A1 of the detergent corresponding to this weight based on the weight G1 of the clothes. Compare A and A1. If A > A1, control the liquid storage device to suck back the excess detergent.

[0105] If A < A1, determine if there is detergent in the liquid storage device. If so, control the liquid storage device to directly drain an appropriate amount of detergent back into the accommodation chamber; if not, remind the user to add detergent.

[0106] Specifically, compare A and A1. If A < A1, determine if there is detergent in the liquid storage device. If there is detergent in the liquid storage device, the liquid storage device directly adds the detergent in the liquid storage chamber to the accommodation chamber; if there is no detergent in the liquid storage device, remind the user to add detergent.

[0107] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of this patent, without departing from the scope of the technical solution of the present invention, can make some changes or modifications using the technical content prompted above as equivalent embodiments of equivalent changes.
