Description

Technical Field

[0001] The invention relates to the field of washing machines, in particular to a drum washing machine. Background Art

[0002] With the development of science and technology, automatic dispensing technology for washing machines is increasingly being applied to the working process of washing machines. Automatic dispensing technology can automatically and accurately add detergent dosage according to the amount of clothes, which can largely avoid the situation where manual detergent dispensing leads to inaccurate detergent dosage; on the other hand, automatic detergent dispensing technology can dispense a large amount of detergent at a time, which can be used for a long time after one dispensing, greatly saving the time cost of dispensing detergent every time washing clothes. However, because it is an automatic dispensing technology, when there is not much detergent left, especially when it is not enough for the one-time dosage of detergent additives, the amount of detergent dispensed will be insufficient, so it is necessary to detect the amount of detergent additives so that an alarm can be issued in time when the liquid level is insufficient to remind the user to add detergent additives.

[0003] In some existing washing machines that can automatically dispense detergent, the liquid outlet of the detergent box and the liquid level detection mechanism used to detect the liquid level of the detergent and issue a prompt are relatively independent structures. Such a structure makes the structure of the detergent storage device relatively complex and greatly increases its manufacturing cost. Due to the space limitation of the washing machine itself, if the structure of the detergent storage device is complex, it may occupy the space inside the washing machine and even affect the capacity of the detergent box itself. Existing liquid level detection structures mostly use reed switch type liquid level detection mechanisms. Chinese patent application number 201310265486.7 discloses a detergent supply device and a washing machine having the same, wherein a liquid level detection mechanism is arranged at a liquid outlet, comprising a slide bar arranged in a vertical direction, the slide bar is connected to the liquid outlet cover and extends into the box body, the slide bar is provided with two iron sheets arranged at intervals and extending in the axial direction of the slide bar; a magnetic floating ring, the magnetic floating ring is sleeved on the slide bar and can move up and down in the axial direction of the slide bar, so that when the magnetic floating ring moves to a predetermined position, the two iron sheets are turned on; and a controller, the controller is respectively connected to the two iron sheets through wires. Although the invention can measure the liquid level at the liquid outlet, since a liquid level detection mechanism is provided at the liquid outlet, the structure at the liquid outlet is complicated. The reed switch type liquid level detection mechanism is complicated in itself, making the structure at the liquid outlet more complicated. The assembly is complicated and requires professionals, which increases the cost. At the same time, the accuracy of liquid level detection is not high, and the detection of low liquid level is not sensitive enough, which is prone to false alarms or delayed alarms, causing great inconvenience to customers.

[0004] In addition, the existing detergent additive container connection is mostly a non-removable structure, which makes it impossible to remove the detergent additive container for liquid replenishment when the liquid level is low. Even if some detergent additive containers can be removed, they are complex in structure and difficult for ordinary users to operate.

[0005] Furthermore, the detergent additive containers of existing drum washing machines are mostly installed in obvious positions such as the top or upper left of the washing machine, occupying a large amount of space on the top or upper left of the washing machine. In addition, due to the narrow space above the drum washing machine, the detergent additive containers of these washing machines are generally long strips extending along the longitudinal direction of the washing machine, making it difficult for users to check the remaining amount of detergent in the storage box, and it is not conducive to users to add detergent additives in time. In addition, for double-drum washing machines, the detergent additive container is set on the top of the washing machine, which requires a long delivery pipeline connected to the lower washing drum, causing many inconveniences.

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

[0056] The specific implementation modes of the present invention will be further described below in conjunction with the accompanying drawings.

[0057] Embodiment 1

[0058] like Figure 1-3 As shown, a drum washing machine includes a box body and

[0059] A container for detergent additives 1,

[0060] The mounting portion 2 for carrying the container 1 is disposed on the box body, and the container 1 is detachably disposed in the mounting portion 2.

[0061] A dosing system for dosing the detergent additive in the container 1 into the washing tub.

[0062] In the above scheme, the drum washing machine includes a box body. The container 1 of the existing drum washing machine is mostly installed in an obvious position such as the top or upper left of the washing machine, occupying a large amount of space on the top or upper left of the washing machine. Due to the narrow space above the drum washing machine, the container 1 of these washing machines is generally long and extends along the longitudinal direction of the washing machine, which makes it difficult for users to check the remaining amount of detergent in the storage box, and is not conducive to users adding washing additives in time. Because of the narrow structure and complex circuits, it is not easy to take out and place the container 1, which makes it very inconvenient for users to add washing additives. The container 1 of the present invention is detachably arranged in the mounting part 2, and the mounting part 2 is arranged on the mounting base, which saves space above the washing machine. At the same time, the size of the container 1 can be increased, and the narrow structure is no longer adopted, which makes it more convenient to replenish the washing additive in the container 1 or take out the container 1 for liquid replenishment. In addition, in one embodiment, the drum washing machine is a double-drum washing machine, that is, a double-drum washing machine including two upper and lower drums. The double-drum washing machine has a larger box body because it needs to accommodate two drums, and after the container 1 is set at the top or upper left of the washing machine, the drum located at the bottom needs to be added with a long pipeline or an additional container 1 to add detergent additives, which invisibly increases the complexity of the container 1 and the difficulty of adding detergent additives, and is prone to pipeline blockage or damage. In the present invention, the container 1 is set on the box body through the mounting portion 2, saving space at the top of the washing machine. At the same time, the container 1 can also be set at a position close to both washing drums, and the mounting portion 2 can be set at a position close to both washing drums. In addition, because the container 1 cannot be installed inside the washing drum, the detergent additive needs to be put into the washing drum from the container 1. A delivery system is required for delivery.

[0063] Furthermore, the washing machine further comprises a front plate 3, and the mounting portion 2 is detachably arranged at the rear of the front plate 3.

[0064] Preferably, the mounting portion 2 is a container structure, and more preferably, the mounting portion 2 is a thin rectangular parallelepiped.

[0065] Preferably, the mounting portion 2 is provided with a connecting boss 16 protruding from the mounting portion 2, and the mounting portion 2 is connected to the front plate 3 via the connecting boss 16.

[0066] More preferably, the connecting boss 16 includes a screw hole 17, and the mounting portion 2 is connected to the front plate 3 via screws.

[0067] In the above scheme, the mounting portion 2 is arranged behind the front plate 3, which saves the space above the washing machine, and at the same time, the size of the container 1 can be increased. The narrow and long structure is no longer adopted, which makes it more convenient to replenish the washing additive in the container 1 or take out the container 1 for liquid replenishment. The installation of the mounting portion 2 is also more convenient and firm. In a preferred embodiment, the mounting portion 2 is a container structure, which is in the shape of a thin rectangular parallelepiped. On the premise of not occupying the space in the washing machine box, the size of the container 1 can be increased. However, the thin rectangular parallelepiped container 1 causes the delivery system in the mounting portion 2 to not be completely arranged at the bottom of the container 1. At the same time, the delivery system arranged at the bottom of the container 1 is not convenient for water to flush the washing additive into the washing drum. Therefore, in a more preferred embodiment, the delivery system is partially arranged on the side of the container 1. In a preferred embodiment, the connecting boss 16 is arranged on a protrusion protruding from the side of the mounting portion 2, and the screw passes through the connecting boss 16 to fix the mounting portion 2 to the rear of the front plate 3.

[0068] Furthermore, the delivery system includes a delivery cavity 20 disposed at the bottom of the container 1, a delivery port communicating with the container 1 and the delivery cavity 20 is disposed at the bottom of the container 1, and a delivery switch 21 is disposed in the delivery port.

[0069] Preferably, the delivery cavity 20 is arranged in the mounting portion 2.

[0070] Preferably, the delivery switch 21 opens the delivery port when the container 1 is placed in the mounting portion 2 , and closes the delivery port when the container 1 is taken out of the mounting portion 2 .

[0071] In the above scheme, the delivery cavity 20 is arranged at the bottom of the container 1, and the washing additive is delivered to the delivery cavity 20 arranged at the bottom under the action of gravity, which makes it easier to deliver the washing additive from the container 1 to the delivery cavity 20, and the structure is simple and space-saving. In a preferred embodiment, the delivery cavity 20 is arranged in the mounting portion 2, which saves space and facilitates the delivery of the washing additive. A delivery switch 21 is provided to control the delivery of the washing additive, to prevent accidental delivery of the washing additive, and to prevent the remaining washing additive from continuing to be delivered when the container 1 is taken out, thereby contaminating the mounting portion 2, the container 1 and the washing machine, and causing inconvenience to the user.

[0072] Furthermore, the delivery system further includes a water inlet chamber 22, which includes a liquid inlet connected to the delivery chamber 20, a water inlet connected to the water inlet pipe, and a liquid outlet connected to the washing tub. After the washing additive enters the water inlet chamber 22 from the liquid inlet, the water in the water inlet is flushed into the washing tub from the liquid outlet.

[0073] Preferably, the water inlet cavity 22 is arranged on the side of the container 1 .

[0074] In the above scheme, after the washing additive enters the water inlet chamber 22 through the liquid inlet, the water inlet dilutes the washing additive and flushes the washing additive into the washing tub through the liquid outlet. The water inlet chamber 22 is arranged on the side of the container 1, which is more convenient for connecting the water inlet pipe and for connecting the pipeline with the washing tub. The water inlet chamber 22 is arranged on the side of the container 1, which is convenient for pipeline connection, saves pipelines, and does not occupy space. The water inlet chamber 22 is arranged on the side of the container 1 and is fixedly installed on the box body / behind the front plate 3 through the mounting portion 2.

[0075] Furthermore, the delivery system also includes an automatic delivery structure.

[0076] Preferably, the automatic delivery structure further includes a siphon pipeline 23, and the delivery chamber 20 is connected to the liquid inlet of the water inlet chamber 22 through the siphon pipeline 23.

[0077] More preferably, a negative pressure pipeline is further provided between the siphon pipeline 23 and the liquid inlet.

[0078] In the above scheme, the siphon pipeline 23 facilitates the thorough delivery of the washing additives in the delivery chamber 20, avoiding the contamination of the delivered washing additives by the residual washing additives, or the corrosion of the chamber or pipeline caused by the residual washing additives for a long time. Because the water inlet chamber 22 is arranged on the side of the container 1, the washing additives cannot enter the water inlet chamber 22 from the delivery chamber 20 under the action of their own gravity, and there is a height difference. The delivery of the washing additives is achieved through the siphon pipeline 23, eliminating the influence of the height difference, so that the delivery of the washing additives is more thorough and without residue. In a preferred embodiment, a negative pressure pipeline is also provided between the siphon pipeline 23 and the liquid inlet, and the negative pressure pipeline provides negative pressure for the siphon pipeline 23, which makes it easier for the siphon pipeline 23 to suck out the washing additives from the delivery chamber 20 and deliver them into the water inlet chamber 22 to avoid residue.

[0079] Furthermore, the delivery system also includes a quantitative unit for controlling the quantitative delivery of the detergent additive.

[0080] Preferably, the quantitative unit includes a constant volume valve and a flow meter 24, wherein the constant volume valve is arranged between the delivery chamber 20 and the liquid inlet of the water inlet chamber 22, and the flow meter 24 is arranged at the liquid inlet. The constant volume valve is opened / closed according to the measurement result of the flow meter 24.

[0081] More preferably, the constant volume valve is arranged between the siphon pipeline 23 and the liquid inlet.

[0082] Also preferably, the delivery system is provided with two siphon pipelines 23 connected in series, and the constant volume valve is provided between the two siphon pipelines 23 .

[0083] In the above scheme, the constant volume valve and flow meter 24 are provided to realize the quantitative automatic delivery of the washing additive. After the flow meter 24 measures the flow of the washing additive, the delivery amount of the washing additive is calculated according to the flow size and time. When the delivery amount meets the set delivery amount, the constant volume valve is closed to stop the delivery of the washing additive. In a preferred embodiment, the constant volume valve is arranged between the siphon line 23 and the liquid inlet, and the control is more accurate and convenient. In a more preferred embodiment, the delivery system is provided with two siphon lines 23 in series to more thoroughly deliver the washing additive into the water inlet chamber 22, because the water inlet chamber 22 is arranged on the side of the container 1, and there is a height difference between the liquid inlet of the water inlet chamber 22 and the delivery chamber 20, and the siphon line 23 is provided to eliminate the height difference, so as to achieve the delivery of the washing additive, and two siphon lines 23 in series are provided to reduce the siphon line 23, and eliminate the height difference without occupying space, so as to achieve the delivery of the washing additive.

[0084] Furthermore, the delivery system further includes an independent air-permeable cavity 26, the bottom of which is connected to the outer cylinder via a hose.

[0085] Preferably, the air permeable cavity 26 is arranged on the side of the water inlet cavity 22 .

[0086] In the above scheme, the bottom of the air-permeable cavity 26 is connected to the outer cylinder through a hose for ventilation of the inner cylinder. In a preferred embodiment, the air-permeable cavity 26 is arranged on the side of the water inlet cavity 22 to save space. More preferably, the air-permeable cavity 26 is integrally formed in the water inlet cavity 22 to save space and simplify processing.

[0087] In a preferred embodiment, the container 1 includes two accommodating chambers for accommodating washing additives, respectively accommodating detergent and softener. A delivery system is provided for each accommodating chamber, each delivery system includes a delivery chamber 20 provided at the bottom of the container 1 and connected to the accommodating chambers, and also includes two sections of siphon pipes 23 connected in series and connected to the delivery chamber 20, a constant volume valve is provided between the siphon pipes 23, a negative pressure pipe for providing negative pressure to the siphon pipes 23, and a water inlet chamber 22 connected to the siphon pipes 23 and the water inlet pipes. After the washing additives enter the delivery chamber 20 from the accommodating chamber of the container 1, they enter the water inlet chamber 22 through the siphon pipe 23, the constant volume valve, and the siphon pipe 23, and the water entering from the water inlet of the water inlet chamber 22 is flushed into the washing tub.

[0088] Furthermore, the washing machine also includes a spray chamber 25, which is arranged at the bottom of the container 1 and includes a water inlet hole connected to the water inlet pipe and a water outlet hole connected to the spray pipe.

[0089] Preferably, the spray chamber 25 is disposed in the mounting portion 2 .

[0090] In the above scheme, the spray chamber 25 is used for spraying the door body and window pad, etc., and includes a water inlet hole connected to the water inlet pipe and a water outlet hole connected to the spray pipe. The spray chamber 25 is arranged in the mounting portion 2, that is, arranged on the front plate 3, which is more convenient for spraying and saves space. The spray chamber 25 is integrally formed in the mounting portion 2, has a simple structure, saves processing and installation steps, and reduces costs.

[0091] Furthermore, the front plate 3 includes a clothing inlet 12 for accommodating the machine door, and the container 1 is detachably arranged in the mounting portion 2 through the clothing inlet 12 .

[0092] In the above scheme, the container 1 is detachably arranged in the mounting part 2 through the clothing inlet 12, so that the removal and installation of the container 1 are more convenient, and even if the container 1 is not taken out, it is convenient to supplement the washing additive at the clothing inlet 12. The mounting part 2 is arranged behind the front plate 3. When the washing machine door is opened, the container 1 can be taken out from the clothing inlet 12. When the washing machine door is closed, the user cannot see the container 1 from the outside, so that the drum washing machine has better integrity and is more beautiful. The container 1 can be pulled out and put in from the surrounding wall of the clothing inlet 12 to the left and right, or pulled out and put in from the up and down directions. In this embodiment, when the drum washing machine is a double drum washing machine, the preferred embodiment is that the container 1 is arranged at the clothing inlet 12 located at the top. The container 1 is arranged at the clothing inlet 12 located at the top, so that the distance between the container 1 and the two washing drums is not far, and the washing additive can be put in without the help of a long pipeline, which simplifies the container 1, saves space, saves materials, reduces costs, and the pipeline is not easy to be blocked or damaged.

[0093] Furthermore, the clothing loading port 12 is provided with a mounting hole, and the container 1 is detachably arranged in the mounting hole.

[0094] Preferably, the mounting hole is arranged at the bottom of the clothing loading port 12 .

[0095] In the above scheme, since there is little space on the left and right sides of the clothing inlet 12 of the front plate 3 of the drum washing machine, the container 1 and the mounting portion 2 are generally arranged on the upper and lower sides of the clothing inlet 12 of the front plate 3, and since the upper side has high requirements for sealing and the placement of detergent additives, it is preferably arranged below the clothing inlet 12. In a double-drum washing machine, it is arranged below the clothing inlet 12 located at the top, which makes it easier for the container 1 to place detergent additives in the two washing drums.

[0096] Embodiment 2

[0097] In this embodiment, the difference from the first embodiment is that the mounting portion is a bracket structure.

[0098] Embodiment 3

[0099] like Figure 3-5 As shown, a drum washing machine includes a housing, a container 1 for containing detergent additives and a mounting portion 2 for supporting the container 1, wherein the housing includes a mounting base, the mounting portion 2 is arranged on the mounting base, and the container 1 is detachably arranged in the mounting portion 2.

[0100] In the above scheme, the drum washing machine includes a box body. The container 1 of the existing drum washing machine is mostly installed in an obvious position such as the top or upper left of the washing machine, occupying a large amount of space on the top or upper left of the washing machine. Due to the narrow space above the drum washing machine, the container 1 of these washing machines is generally long and extends along the longitudinal direction of the washing machine, which makes it difficult for users to check the remaining amount of detergent in the storage box, and is not conducive to users adding washing additives in time. Because of the narrow structure and complex circuits, it is not easy to take out and place the container 1, which makes it very inconvenient for users to add washing additives. The container 1 of the present invention is detachably arranged in the mounting part 2, and the mounting part 2 is arranged on the mounting base, which saves space above the washing machine. At the same time, the size of the container 1 can be increased, and the narrow structure is no longer adopted, which makes it more convenient to replenish the washing additive in the container 1 or take out the container 1 for liquid replenishment. In addition, in one embodiment, the drum washing machine is a double-drum washing machine, that is, a double-drum washing machine including two upper and lower drums. The double-drum washing machine has a larger cabinet due to accommodating two drums, and after the container 1 is arranged at the top or upper left of the washing machine, if detergent additives want to be added to the drum located below, it needs to be achieved through a long pipeline or the like or by adding a container 1, which invisibly increases the complexity of the container 1 and the difficulty of adding detergent additives, and is very likely to cause problems such as pipeline blockage or damage. In the present invention, the cabinet includes a mounting base, and the container 1 is arranged on the mounting base through the mounting portion 2, which saves space on the top of the washing machine. At the same time, the container 1 can also be arranged at a position close to both washing drums, and the mounting base can be arranged at a position close to both washing drums.

[0101] Furthermore, the washing machine further comprises a front plate 3 , the mounting base is arranged behind the front plate 3 , and the mounting portion 2 is detachably arranged on the mounting base behind the front plate 3 .

[0102] In the above solution, the mounting base is arranged behind the front plate 3, which saves space above the washing machine and increases the size of the container 1. The narrow and long structure is no longer adopted, which makes it more convenient to add detergent additives in the container 1 or take out the container 1 for liquid replenishment. The installation of the mounting part 2 is also more convenient and firm.

[0103] Furthermore, the front plate 3 includes a clothing inlet 12 for accommodating the machine door, and the container 1 is detachably arranged in the mounting portion 2 through the clothing inlet 12 .

[0104] In the above scheme, the container 1 is detachably arranged in the mounting part 2 through the clothing inlet 12, so that the removal and installation of the container 1 are more convenient, and even if the container 1 is not taken out, it is convenient to supplement the washing additive at the clothing inlet 12. The mounting part 2 is arranged behind the front plate 3. When the washing machine door is opened, the container 1 can be taken out from the clothing inlet 12. When the washing machine door is closed, the user cannot see the container 1 from the outside, so that the drum washing machine has better integrity and is more beautiful. The container 1 can be pulled out and put in from the surrounding wall of the clothing inlet 12 to the left and right, or pulled out and put in from the up and down directions. In this embodiment, when the drum washing machine is a double drum washing machine, the preferred embodiment is that the container 1 is arranged at the clothing inlet 12 located at the top. The container 1 is arranged at the clothing inlet 12 located at the top, so that the distance between the container 1 and the two washing drums is not far, and the washing additive can be put in without the help of a long pipeline, which simplifies the container 1, saves space, saves materials, reduces costs, and the pipeline is not easy to be blocked or damaged.

[0105] Furthermore, the mounting base includes a mounting beam 15 disposed behind the front plate 3. Preferably, the mounting beam 15 is disposed on the box frame.

[0106] In the above scheme, the mounting base includes a mounting beam 15 arranged behind the front plate 3. The mounting beam 15 does not occupy extra space in the washing machine, thereby saving space in the washing machine, increasing the volume of the container, and can be connected to the fixed mounting portion 2, and the container 1 is arranged behind the front plate 3, which is concealed and beautiful. The mounting beam 15 is arranged on the box frame, and can also play a role in enhancing the strength of the box / box frame. In one implementation of this embodiment, the drum washing machine is a double-drum washing machine, that is, a double-drum washing machine including two upper and lower drums. The double-drum washing machine has a larger box body due to the need to accommodate two drums, so the requirement for the strength of the box body is higher. In this embodiment, the mounting beam is arranged on the box frame, which on the one hand enhances the strength of the box body / box frame, and on the other hand, the mounting portion 2 is arranged on the mounting beam, which occupies less space and is installed separately from the box body. When disassembling and repairing the box body, etc., there is no need to consider the problem of affecting the mounting portion 2, because the mounting portion 2 is connected to various pipelines, and if it is disassembled and repaired together with the box body, it will greatly increase the trouble of disassembly and repair.

[0107] Furthermore, the mounting portion 2 includes a connecting portion, and the mounting portion 2 is detachably connected to the mounting beam 15 via the connecting portion.

[0108] In the above solution, the connecting portion is used to detachably connect the mounting portion 2 to the mounting beam 15. The detachable connection makes the mounting portion 2 easy to maintain and inspect.

[0109] Furthermore, the connecting portion includes a connecting boss 16 protruding from the mounting portion 2, and the mounting portion 2 is connected to the mounting beam 15 via the connecting boss 16. Preferably, the connecting boss 16 includes a screw hole 17, and the mounting portion 2 is connected to the mounting beam 15 via screws.

[0110] Furthermore, the connecting portion also includes a connecting hook 18 protruding from the mounting portion 2, and the mounting portion 2 is hung on the mounting beam 15 through the connecting hook 18. Preferably, the mounting beam 15 is a mounting beam, and the mounting portion is hung on the mounting beam through the connecting hook 18.

[0111] In the above scheme, the connecting part may include only the connecting boss 16, or only the connecting hook 18. However, since the mounting part 2 is arranged in the washing machine, it is inevitable that it will shake. Therefore, if only the connecting hook 18 is included, the mounting part 2 will inevitably move and the mounting part 2 cannot be fixed. When only the connecting boss 16 is included, the connecting boss 16 is subjected to greater pressure and is also easily damaged. In this embodiment, both the connecting boss 16 and the connecting hook 18 are included for connection, so that the installation stability of the mounting part 2 is strong.

[0112] Furthermore, a mounting hole is provided in the clothing loading port 12, and the container 1 is detachably disposed in the mounting portion 2 through the mounting hole.

[0113] Furthermore, a mounting hole is provided on the bottom wall of the clothing loading port 12 , and the mounting portion 2 is arranged below the mounting hole. The container 1 is pulled out upward from the mounting hole / placed downward in the mounting portion 2 .

[0114] In the above scheme, since there is little space on the left and right sides of the clothing inlet 12 of the front plate 3 of the drum washing machine, the container 1 and the mounting portion 2 are generally arranged on the upper and lower sides of the clothing inlet 12 of the front plate 3, and since the upper side has high requirements for sealing and the placement of detergent additives, it is preferably arranged below the clothing inlet 12. In a double-drum washing machine, it is arranged below the clothing inlet 12 located at the top, which makes it easier for the container 1 to place detergent additives in the two washing drums.

[0115] Furthermore, the container 1 comprises

[0116] A liquid replenishing port 4 for replenishing washing additives, preferably the liquid replenishing port 4 is arranged at the mounting hole, and more preferably, the drum washing machine further comprises a protective cover 13 for protecting the container 1, and the protective cover 13 is arranged at the mounting hole;

[0117] The liquid outlet 5 for adding washing additives is provided with a liquid outlet valve at the liquid outlet 5. The liquid outlet valve controls the liquid outlet 5 to open when the container 1 is installed in the installation part 2, and to seal and close when the container 1 is taken out of the installation part 2. Preferably, the liquid outlet valve is a one-way valve.

[0118] Furthermore, the container 1 includes at least one liquid storage cavity for containing washing additives, and each liquid storage cavity includes a liquid replenishing port 4 and a liquid outlet 5 .

[0119] In the above scheme, when the liquid replenishing port 4 is arranged at the mounting hole, it is convenient for the user to replenish the washing additive when the container 1 is not taken out or cannot be taken out, and no parts need to be disassembled, and it can be performed by simply opening the machine door. The liquid outlet valve is arranged so that the washing additive can be normally added to the container 1 after installation, and when the container 1 is taken out for replenishing the washing additive, the liquid will not leak from the liquid outlet 5. The protective cover 13 is provided with an opening portion 14 for conveniently opening the protective cover 13. The protective cover 13 is provided to protect the container 1 to prevent dust or liquid from entering the container 1 and contaminating the washing additive, and it also has a sealing effect to prevent the container 1 from leaking. In particular, when the liquid replenishing port 4 is arranged at the mounting hole, the protective cover 13 covers the liquid replenishing port 4 for protection.

[0120] Furthermore, the container 1 further comprises a taking-out portion 19 for facilitating taking out / installing from the mounting portion 2. Preferably, the taking-out portion 19 is a recessed portion provided on the container 1 for facilitating picking by hand.

[0123] In the above scheme, the container 1 of the existing drum washing machine is mostly installed in an obvious position such as the top or upper left of the washing machine, occupying a large amount of space on the top or upper left of the washing machine. Due to the narrow space above the drum washing machine, the container 1 of these washing machines is generally long and extends in the longitudinal direction of the washing machine, which makes it difficult for users to check the remaining amount of detergent in the storage box, and is not conducive to users to add washing additives in time. In addition, due to the narrow and long structure and complex circuits, it is not easy to take out and place the container 1, which makes it very inconvenient for users to add washing additives. The container 1 of the present invention is detachably arranged in the mounting portion, and the mounting portion 2 is arranged on the front plate 3, which saves space above the washing machine. At the same time, the size of the container 1 can be increased, and the narrow and long structure is no longer adopted, which makes it more convenient to replenish the washing additives in the container 1 or take out the container 1 for liquid replenishment.

[0124] Furthermore, the front panel includes a clothing inlet 12 for accommodating the machine door, and the container 1 is detachably arranged in the mounting portion 2 through the clothing inlet 12. Preferably, the mounting portion 2 is arranged on the rear wall of the front panel 3.

[0125] In the above scheme, the container 1 is detachably arranged in the mounting portion 2 through the clothing inlet 12, making it more convenient to take out and install the container 1. At the same time, even if the container 1 is not taken out, it is convenient to replenish the washing additive at the clothing inlet. The mounting portion 2 is arranged on the rear wall of the front plate 3. When the washing machine door is opened, the container 1 can be taken out from the clothing inlet 12. When the washing machine door is closed, the user cannot see the container from the outside, making the drum washing machine more integrated and more beautiful. The container 1 can be pulled out from the surrounding wall of the clothing inlet 12 to the left and right, or pulled out and put in the upward and downward directions.

[0126] Furthermore, a mounting hole is provided in the clothing delivery opening 12, and the container 1 is detachably arranged in the mounting portion 2 through the mounting hole.

[0127] Furthermore, a mounting hole is provided on the bottom wall of the clothing loading port 12 , and the mounting portion 2 is arranged below the mounting hole. The container 1 is pulled out upward from the mounting hole / placed downward in the mounting portion 2 .

[0128] In the above scheme, since there is little space on the left and right sides of the clothing inlet 12 of the front plate 3 of the drum washing machine, the container 1 and the mounting portion 2 are generally arranged on the upper and lower sides of the clothing inlet 12 of the front plate. Since the upper side has high requirements for sealing and the placement of washing additives, it is preferably arranged below the clothing inlet 12.

[0129] Furthermore, the container 1 comprises

[0130] A liquid replenishing port 4 for replenishing washing additives, preferably the liquid replenishing port 4 is arranged at the mounting hole;

[0131] The liquid outlet 5 for adding washing additives is provided with a liquid outlet valve at the liquid outlet 5. The liquid outlet valve controls the liquid outlet 5 to open when the container 1 is installed in the installation part 2, and to seal and close when the container 1 is taken out from the installation part 2. Preferably, the liquid outlet valve is a one-way valve.

[0132] Furthermore, the container 1 comprises at least one liquid storage cavity for containing washing additives, and each liquid storage cavity comprises a liquid replenishing port 4 and a liquid outlet 5 .

[0133] In the above solution, when the liquid replenishing port 4 is arranged at the mounting hole, it is convenient for the user to replenish the detergent additive when the container 1 is not taken out or cannot be taken out, and it can be performed by simply opening the machine door without disassembling any parts. The liquid outlet valve is arranged so that the container 1 can be normally filled with detergent additives after installation, and liquid will not leak from the liquid outlet when the container 1 is taken out for replenishing the detergent additive.

[0134] Furthermore, the drum washing machine also includes a delivery portion, which is connected to the washing tub and the liquid outlet 5 respectively so as to deliver the washing additive in the container 1 into the washing tub.

[0135] In the above scheme, the delivery part is a negative pressure automatic delivery structure, or the delivery part is a suction pump delivery structure, or the delivery part includes a siphon structure.

[0136] Furthermore, the drum washing machine also includes a liquid level detection structure, and the liquid level detection structure includes

[0137] A conductive portion 7 connected to the circuit, wherein the conductive portion 7 is disposed in the mounting portion 2;

[0138] The detection part 6 has one end sealed and inserted into the liquid storage cavity of the container 1, and the other end contacts the conductive part 7 to conduct the circuit to detect the liquid level when the container 1 is set in the installation part 2, and is separated from the conductive part 7 to disconnect the circuit when the container 1 is taken out from the installation part 2.

[0139] Furthermore, the detection part 6 is a conductive probe; the conductive part 7 is a spring structure connected to the connection terminal through a signal line, and the other end of the detection part 6 is pluggably connected to the spring structure.

[0140] Furthermore, the drum washing machine further comprises a protective cover 13 for protecting the container 1 , wherein the protective cover 13 is arranged at the mounting hole. Preferably, the protective cover 13 at least covers the liquid replenishing port 4 when closed.

[0141] Furthermore, the protection cover 13 is provided with an opening portion 14 for conveniently opening the protection cover 13 .

[0142] In the above solution, the protective cover 13 is provided to protect the container 1, preventing dust or liquid from entering the container 1 and contaminating the detergent additive, and also has a sealing effect to prevent leakage of the container 1. In particular, when the liquid filling port 4 is provided at the mounting hole, the protective cover 13 covers the liquid filling port 4 for protection.

[0143] Furthermore, the installation hole also includes a limiting structure for installing the limiting container 1. Preferably, the limiting structure is a protrusion protruding from the side wall of the container 1.

[0144] In the above solution, the limiting structure makes the disassembly or placement of the container 1 simpler and more convenient, and avoids problems such as misplacement, thereby avoiding the inability to automatically dispense detergent additives or detect liquid levels normally caused by misplacement.

[0145] Embodiment 5

[0146] like Figure 6-8 As shown, in this embodiment, a drum washing machine includes

[0147] A front plate 3, wherein the front plate 3 includes a clothing loading opening 12 for accommodating a machine door;

[0148] A container 1 for containing washing additives is arranged in a clothes loading opening 12 of the front plate.

[0149] In the above scheme, the container 1 of the existing drum washing machine is mostly installed in an obvious position such as the top or upper left of the washing machine, occupying a large amount of space on the top or upper left of the washing machine. Due to the narrow space above the drum washing machine, the container 1 of these washing machines is generally long and extends in the longitudinal direction of the washing machine, which makes it difficult for users to check the remaining amount of detergent in the storage box, and is not conducive to users adding washing additives in time. Because of the narrow structure and complex circuits, it is not easy to take out and place the container 1, which makes it very inconvenient for users to add washing additives. The container 1 of the present invention is arranged in the clothing inlet 12 on the front plate 3, saving space above the washing machine, while increasing the size of the container 1, and no longer adopting a narrow and long structure, which makes it more convenient to replenish the washing additive in the container 1 or take out the container 1 for liquid replenishment. In addition, when the washing machine door is opened, the container 1 can be taken out from the clothing inlet 12. When the washing machine door is closed, the user cannot see the container from the outside, making the drum washing machine better in integrity and more beautiful. The container 1 can be pulled out and placed from the surrounding wall of the clothing inlet 12 to the left and right, or pulled out and placed in the upward and downward directions.

[0150] Furthermore, a mounting hole is provided in the clothing loading port 12, and the container 1 is detachably disposed in the mounting hole.

[0151] Furthermore, the drum washing machine also includes a protection cover 13 for protecting the container 1, and the protection cover 13 is arranged at the mounting hole.

[0152] In the above solution, a protective cover 13 is provided to protect the container 1 to prevent dust or liquid from entering the container 1 and contaminating the detergent additive, and also has a sealing effect to prevent the container 1 from leaking.

[0153] Furthermore, the shape of the protection cover 13 matches the shape of the mounting hole, and the shape of the container 1 matches the shape of the mounting hole.

[0154] In the above solution, the shape of the protective cover 13 matches the shape of the container 1, so the protective cover 13 can be better installed and better protect. The shape of the container 1 matches the shape of the mounting hole, making installation simpler and more convenient, and can be compactly arranged to avoid problems such as misalignment or installation delay.

[0155] Furthermore, one end of the protection cover 13 is hinged to the mounting hole, and the other end can be movably flipped around the hinged end to open or close the mounting hole.

[0156] In the above solution, the protection cover 13 can be snapped into the mounting hole, or can be connected to the mounting hole by threads. In this embodiment, the protection cover 13 is hinged to the mounting hole.

[0157] Furthermore, the protective cover is provided with an opening portion for conveniently opening the protective cover.

[0158] In the above solution, in order not to interfere with the opening and closing of the machine door, the protective cover 13 is on the same plane as the clothing inlet 12 or is lower than the plane where the clothing inlet 12 is located. At this time, it becomes very difficult to open the closed protective cover 13. It is difficult to open it directly by hand, and it may be necessary to use a slender foreign object to assist in opening, which adds trouble to the user. Therefore, the present invention is provided with an opening cover 14 to facilitate opening the protective cover 13 to take out the container 1 to add detergent additives or directly add detergent additives to the container 1.

[0159] Furthermore, the mounting hole is arranged at the bottom of the clothing loading port 12, and the protective cover 13 is arranged above the mounting hole.

[0160] In the above solution, there is more space below the front plate 3 , the mounting hole is arranged at the bottom of the clothing loading port 12 , and the container self-mounting hole is arranged below the front plate 3 .

[0161] Furthermore, the container 1 is a box-shaped structure with at least a rectangular upper surface, the surface of the clothing inlet 12 on which the mounting hole is arranged is a plane, and the upper surface of the protective cover 13 is lower than or parallel to the plane.

[0162] In the above solution, the upper surface of the protection cover 13 is lower than or parallel to the plane where the mounting hole is set, so as not to interfere with the opening and closing of the door.

[0163] Furthermore, the protective cover 13 is provided with an opening portion 14 for conveniently opening the protective cover 13 . Preferably, the opening portion 14 is a notch provided on the protective cover 13 for easy hand picking. More preferably, the notch is a notch provided on the other movable end of the protective cover 13 .

[0164] Furthermore, the installation hole includes a limiting portion for installing the limiting container 1.

[0165] In the above solution, the limiting part is provided to make the container 1 easier to take and put without causing problems such as misplacement, thereby avoiding the inability to automatically dispense detergent additives or to detect liquid levels normally caused by misplacement.

[0166] Embodiment 6

[0167] like Figure 9-11As shown, in this embodiment, the washing machine further includes at least one group of liquid level detection structures for detecting the liquid level in the container 1 .

[0168] In the above scheme, because the container 1 is generally connected to various pipelines, etc., it is difficult to take out the container 1 for operations such as refilling, and professional maintenance personnel are required to operate, which causes great inconvenience for users to replenish detergent additives. The container 1 described in the present invention can be taken and placed in the installation part 2, which is convenient for taking out the container 1 for operations such as refilling and maintenance. Because the automatic detergent additive delivery device automatically delivers detergent additives into the washing machine, and the user cannot see the amount of detergent additives in the container 1 with his own eyes when using it, the automatic detergent additive delivery device especially needs a liquid level reminder, especially a minimum liquid level reminder. For ordinary automatic detergent additive delivery devices, it is not necessary to monitor the amount of detergent additives in real time. It is only necessary to issue an alarm reminder and execute relevant procedures when the liquid level of the detergent additive is lower than the minimum liquid level, so as to avoid problems such as incomplete and unclean washing caused by insufficient detergent additives. The container 1 of the present invention is removably arranged in the installation part 2 so as to replenish the detergent additive; the liquid level detection structure can be used for liquid level detection of the removable container 1 arranged in the installation part 2. After the container 1 is taken out to replenish the detergent additive, the liquid level detection can continue to be sensitively and accurately performed after the container 1 is placed.

[0169] Furthermore, the liquid level detection structure includes a detection part 6 and a conductive part 7 connected to the circuit. One end of the detection part 6 is sealed and inserted into the container, and the other end contacts the conductive part 7 to conduct the circuit when the container 1 is placed in the mounting part 2, and is separated from the conductive part 7 to disconnect the circuit when the container 1 is taken out of the mounting part 2.

[0170] In the above scheme, the detection part 6 is used to detect the liquid level, and the conductive part 7 is used to connect the circuit. Because the container 1 is arranged in the mounting part 2 in a removable manner, when the container 1 is taken out, the detection part 6 is taken out along with the container 1, and the detection part 6 leaves the conductive part 7, the circuit is disconnected, and the liquid level cannot be detected; when the container 1 is placed back into the container mounting part 2, the detection part 6 contacts the conductive part 7 again, the circuit is connected, and the liquid level can continue to be detected.

[0171] Furthermore, the liquid level detection structure includes two detection parts 6. When the detergent additive in the container contacts both detection parts 6, the two detection parts 6 are connected through the detergent additive, the liquid level detection structure forms a circuit path, and the detection parts 6 detect that there is enough detergent additive; conversely, if the detergent additive in the container does not contact at least one detection part 6, the circuit between the two detection parts 6 is disconnected, and the liquid level needs to be supplemented with detergent additive.

[0172] In the above scheme, the two detection parts 6 are electrically connected to the control module through the conductive part 7. When the two detection parts 6 are connected, the entire signal circuit is connected and the signal can be transmitted. Otherwise, the entire signal circuit is disconnected and the signal cannot be transmitted. Among them, the two detection parts 6 are connected when they are in contact with the detergent additive in the detergent storage chamber. Because the detergent additive is conductive, when the two detection parts 6 are in contact with the detergent additive, the detergent additive is equivalent to the wire between the two detection parts 6 connecting the two detection parts 6.

[0173] Furthermore, the liquid level detection structure also includes a fixing part 9, the detection part 6 is sealed and wrapped in the fixing part 9, and both ends extend out of the fixing part 9. One end of the detection part 6 is detachably sealed and inserted into the container through the fixing part 9. Preferably, the fixing part 9 is connected to the container 1 by threads.

[0174] In the above solution, the fixing part 9 can be made of insulating material, and the fixing part 9 inserts the detection part 6 into the container. The fixing part 9 itself is not inserted, and the fixing part 9 plays a role of sealing and fixing the detection part 6, making it easier to seal and connect with the container 1.

[0175] Furthermore, one end of the detection part 6 is inserted into the container through a fixing part 9 which is detachably sealed from the bottom of the container 1. The fixing part 9 is made of insulating material. The fixing part 9 is at least partially inserted into the container. The height from the top of the inserted part to the bottom of the container is the lowest measurable liquid level.

[0176] In the above scheme, the detection part 6 of the liquid level detection structure of the present invention is inserted into the container from the bottom of the container 1, which is more convenient for detecting whether the washing additive in the container is sufficient. At the same time, since the liquid outlet 5 is also arranged at the bottom, it is arranged at the bottom for easy installation, and other structures are not added, which saves costs. In this embodiment, the fixing part 9 itself is partially inserted into the container. At this time, the fixing part 9 not only fixes the detection part 6, making it easier to seal and connect with the container 1, but also plays a role in increasing the minimum liquid level. The fixing part 9 is made of insulating material, which increases the height of the minimum liquid level, and the minimum liquid level can be set as needed to ensure that there is enough washing additive in the container at the minimum liquid level.

[0177] Furthermore, when the liquid level of the detergent additive in the container is higher than the fixing part 9, the two detection parts 6 are connected, the liquid level detection structure forms a path, and the detection part detects that there is enough detergent additive; on the contrary, if the liquid level of the detergent additive in the container is lower than the fixing part 9, the circuit between the two detection parts 6 is disconnected, and the liquid level is low and the detergent additive needs to be replenished. In the above scheme, because the fixing part 9 is insulated and non-conductive, when the liquid level is below the fixing part 9, the detection part 6 does not contact the detergent additive in the container 1, and the two detection parts 6 cannot be connected. Only when the liquid level is above the fixing part 9, the detection part 6 contacts and conducts with the detergent additive in the container 1.

[0178] Furthermore, the liquid level detection structure also includes a sealing structure 10 between the sealing fixing portion 9 and the container 1, which is arranged between the container 1 and the fixing portion 9. Preferably, the sealing portion is a sealing ring.

[0179] In the above scheme, the detection part 6 of the liquid level detection structure is inserted into the container 1 from the bottom. The container 1 will be correspondingly provided with a detection hole. The detergent additive is easy to flow out from the detection hole under the action of gravity. The detergent additive that flows out accidentally enters the washing drum and affects the accuracy of the automatic dosage. Or the detergent additive that flows out accidentally flows into other substances in the washing machine body, causing waste and contaminating or corroding other parts. Therefore, the sealing at the detection hole is very important, and it is imperative to provide a sealing structure 10 for sealing.

[0180] Furthermore, the fixing portion 9 includes a sealing protrusion 11 protruding from a side wall thereof, and the sealing structure 10 is disposed between the bottom of the container 1 and the sealing protrusion 11 .

[0181] In the above solution, the fixing part 9 includes a sealing protrusion 11 protruding from its side wall. The sealing protrusion 11 is annular and protrudes from the side wall of the fixing part 9, which has both the function of auxiliary sealing and the function of limiting the fixing part 9. The sealing protrusion 11 is set to facilitate installation.

The water inlet is used to flush the washing additives dispensed from the container 1 into the washing drum; or the automatic dispensing structure is connected to the liquid outlet 5 and the washing drum to automatically dispense the washing additives in the container 1 into the washing drum.

[0185] The automatic dispensing device for detergent additives also includes two groups of liquid level detection structures, and each liquid storage chamber is provided with one group of liquid level detection structures. The liquid level detection structure includes a detection part 6, which is a conductive probe and an insulating fixed part 9.

It also includes a conductive part 7, which is a spring structure connected to the wiring terminal 8 through a signal line, and the other end of the detection part 6 is pluggable and connected to the spring structure. One end of the conductive probe and part of the fixed part 9 are detachably sealed and inserted into the liquid storage chamber. The height at which the fixed part 9 is inserted into the bottom of the liquid storage chamber is the lowest liquid level. The liquid level detection structure is used to detect whether the detergent additives in the liquid storage chamber are sufficient. The other end of the conductive probe is inserted into the spring structure, and the circuit connected to the spring structure is turned on.
