Abstract
Description
Technical Field
[0001] This invention relates to the field of washing machines, and in particular to a drum washing machine. Background Technology
[0002] With the development of science and technology, automatic detergent dispensing technology is increasingly being applied to the operation of washing machines. This technology can precisely add detergent based on the amount of laundry, largely avoiding inaccurate dosages caused by manual detergent dispensing. Furthermore, automatic dispensing allows for a larger volume of detergent to be added at once, lasting for a long time and significantly saving time compared to adding detergent for each wash. However, because it's automatic, insufficient detergent, especially if the remaining amount isn't enough for the initial dispensing, can lead to inadequate dispensing. Therefore, it's necessary to monitor the detergent level and issue an alarm to remind the user to add detergent when the level is low.
[0003] In some existing washing machines that automatically dispense detergent, the outlet for the detergent dispenser and the level detection mechanism for monitoring and alerting the user are relatively independent structures. This structure makes the detergent storage device relatively complex and significantly increases its manufacturing cost. Due to the space constraints of the washing machine itself, a complex detergent storage device may occupy internal space and even affect the capacity of the detergent dispenser. Current level detection structures mostly use reed switch-type level detection mechanisms. Chinese Patent Application No. 201310265486.7 discloses a detergent supply device and a washing machine having the same. The liquid level detection mechanism is located at the liquid outlet and includes a vertically oriented slide rod connected to the liquid outlet cover and extending into the housing. The slide rod contains two spaced-apart iron plates extending axially along the slide rod. A magnetic float is fitted onto the slide rod and can move up and down axially to connect the two iron plates when the magnetic float moves to a predetermined position. A controller is connected to the two iron plates via wires. Although this invention can measure the liquid level at the outlet, the structure at the outlet is complex due to the liquid level detection mechanism. The reed switch-type liquid level detection mechanism is already complex, making the structure at the outlet even more complex. The assembly is complicated, requiring professional personnel and increasing costs. At the same time, the accuracy of liquid level detection is not high, and the detection of low liquid levels is not sensitive enough, which easily leads to false alarms or delayed alarms, causing great inconvenience to customers.
[0004] Furthermore, most existing detergent additive containers have a non-removable structure, making it impossible to remove the container for replenishment when the liquid level is low. Even those detergent additive containers that are removable often have complex structures that are difficult for ordinary users to operate.
[0005] Furthermore, the detergent dispenser containers in most existing front-loading washing machines are installed in prominent locations such as the top or upper left of the machine, occupying a significant amount of space. Due to the limited space above these machines, the dispensers are typically elongated, extending longitudinally, making it difficult for users to check the remaining detergent level and add detergent promptly. Additionally, for twin-drum washing machines, placing the detergent dispenser at the top requires a longer hose connecting to the lower washing drum, causing further inconvenience.
[0006] In view of this, the present invention is proposed. Summary of the Invention
[0007] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a drum washing machine.

[0016] Furthermore, the container includes
[0017] The washing machine also includes a replenishment port for adding detergent additives, preferably located at the mounting hole. More preferably, the drum washing machine further includes a protective cover for the container, which is located at the mounting hole.
[0018] The outlet for adding detergent additives is equipped with an outlet valve. The outlet valve controls the outlet to open when the container is installed in the mounting part and to seal and close when the container is removed from the mounting part. Preferably, the outlet valve is a one-way valve.
[0019] Furthermore, the container also includes a removal part that facilitates removal / installation from the mounting part; preferably, the removal part is a recess on the container that is easy to pry open by hand.

[0038] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0039] Example 1
[0040] like Figure 1-3 As shown, a drum washing machine includes a cabinet, a container 1 for holding detergent additives, and a mounting part 2 for supporting the container 1. The cabinet includes a mounting base, the mounting part 2 is disposed on the mounting base, and the container 1 is detachably disposed in the mounting part 2.
[0041] In the above-described solution, the drum washing machine includes a cabinet. The container 1 of existing drum washing machines is mostly installed in a prominent position such as the top or upper left of the washing machine, occupying a large amount of space. Furthermore, due to the narrow space above the drum washing machine, the container 1 is generally elongated, extending longitudinally, making it difficult for users to see the remaining detergent level and to add detergent additives in a timely manner. The elongated structure and complex wiring also make it difficult to easily remove and place the container 1, resulting in significant inconvenience for users adding detergent additives. In this invention, the container 1 is detachably installed within the mounting part 2, which is mounted on a mounting base. This saves space above the washing machine and allows for a larger container 1. The elongated structure eliminates the need for a long, narrow design, making it easier to replenish detergent additives in the container 1 or to remove the container 1 for refilling. In addition, in one embodiment, the drum washing machine is a twin-drum washing machine, that is, a twin-drum washing machine including two drums, one above the other. The twin-drum washing machine has a large cabinet because it needs to accommodate two drums. After the container 1 is placed on the top or upper left of the washing machine, the lower drum needs to be connected to a long pipe or an additional container 1 to add detergent additives. This increases the complexity of the container 1 and the difficulty of adding detergent additives, and is prone to problems such as pipe blockage or damage. In this invention, the cabinet includes a mounting base, and the container 1 is mounted on the mounting base through the mounting part 2, saving the top space of the washing machine. At the same time, the container 1 can be placed close to both washing drums, and the mounting base can be placed close to both washing drums.
[0042] Furthermore, the washing machine also includes a front panel 3, the mounting base is disposed behind the front panel 3, and the mounting part 2 is detachably disposed on the mounting base behind the front panel 3.
[0043] In the above solution, the mounting base is located behind the front panel 3, saving space above the washing machine. It also allows for an increase in the size of the container 1, eliminating the need for a long and narrow structure and making it easier to replenish the detergent additive in the container 1 or remove the container 1 for refilling. The installation of the mounting part 2 is also more convenient and secure.
[0044] Furthermore, the front panel 3 includes a clothing inlet 12 for accommodating the machine door, and the container 1 is detachably disposed in the mounting part 2 through the clothing inlet 12.
[0045] In the above solution, the container 1 is detachably installed in the mounting part 2 through the clothing inlet 12, making it more convenient to remove and install the container 1. Even without removing the container 1, it is convenient to add detergent additives at the clothing inlet 12. The mounting part 2 is located behind the front panel 3, so the container 1 can only be removed from the clothing inlet 12 when the washing machine door is open. When the washing machine door is closed, the user cannot see the container 1 from the outside, resulting in a better overall appearance and a more aesthetically pleasing design for the drum washing machine. The container 1 can be pulled out from the perimeter of the clothing inlet 12 to the left or right, or pulled out from the top or bottom. In this embodiment, when the drum washing machine is a twin-drum washing machine, the preferred implementation is that the container 1 is located at the upper clothing inlet 12. This placement ensures that the container 1 is not far from either washing drum, eliminating the need for long pipes for adding detergent additives. This simplifies the container 1, saves space and materials, reduces costs, and prevents pipe blockage or damage.
[0046] 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.
[0047] In the above scheme, the mounting base includes a mounting beam 15 disposed behind the front panel 3. The mounting beam 15 does not occupy extra space inside the washing machine, thus saving space and increasing the volume of the container. It can also connect and fix the mounting part 2, placing the container 1 behind the front panel 3 in a concealed and aesthetically pleasing manner. The mounting beam 15 is disposed on the cabinet frame, which also enhances the strength of the cabinet / cabinet frame. In one embodiment of this invention, the drum washing machine is a twin-drum washing machine, that is, a twin-drum washing machine including upper and lower drums. Because the twin-drum washing machine needs to accommodate two drums, the cabinet is larger, and the requirements for cabinet strength are higher. In this embodiment, the mounting beam disposed on the cabinet frame enhances the strength of the cabinet / cabinet frame. On the other hand, the mounting part 2 is disposed on the mounting beam, occupying less space and being installed separately from the cabinet. When disassembling and repairing the cabinet, there is no need to consider the impact on the mounting part 2, because the mounting part 2 connects to various pipes. If it were disassembled and repaired together with the cabinet, it would greatly increase the trouble of disassembly and repair.
[0048] Furthermore, the mounting part 2 includes a connecting part, and the mounting part 2 is detachably connected to the mounting beam 15 via the connecting part.
[0049] In the above scheme, the connecting part is used to detachably connect the mounting part 2 to the mounting beam 15. The detachable connection makes the mounting part 2 easy to maintain and inspect.
[0050] Furthermore, the connecting part includes a connecting boss 16 protruding from the mounting part 2. The mounting part 2 is connected to the mounting beam 15 through the connecting boss 16. Preferably, the connecting boss 16 includes screw holes 17, and the mounting part 2 is connected to the mounting beam 15 through screws.
[0051] Furthermore, the connecting part also includes a connecting hook 18 protruding from the mounting part 2. The mounting part 2 is attached to the mounting beam 15 via the connecting hook 18. Preferably, the mounting beam 15 is a mounting crossbeam, and the mounting part is attached to the mounting crossbeam via the connecting hook 18.
[0052] In the above solution, the connecting part may only include the connecting boss 16 or only the connecting hook 18. However, since the mounting part 2 is located inside 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 cannot be fixed. When only the connecting boss 16 is included, the connecting boss 16 will bear a large pressure and is easily damaged. In this embodiment, both the connecting boss 16 and the connecting hook 18 are included for connection, which makes the installation stability of the mounting part 2 strong.
[0053] Furthermore, the clothing dispensing port 12 is provided with an installation hole, and the container 1 is detachably installed in the mounting part 2 through the installation hole.
[0054] Furthermore, the bottom wall of the clothing inlet 12 is provided with an installation hole, and the installation part 2 is located below the installation hole. The container 1 is pulled out from the installation hole and placed into the installation part 2.
[0055] In the above scheme, since there is little space on both sides of the clothes inlet 12 on the front panel 3 of the drum washing machine, the container 1 and the mounting part 2 are generally located on the upper and lower sides of the clothes inlet 12 on the front panel 3. Furthermore, because the upper side has higher requirements for sealing and the addition of detergent additives, it is preferred to locate them below the clothes inlet 12. In a twin-drum washing machine, locating them below the upper clothes inlet 12 makes it easier for the container 1 to add detergent additives to both washing drums.
[0056] Furthermore, the container 1 includes
[0057] The replenishment port 4 for adding washing additives is preferably located at the mounting hole. More preferably, the drum washing machine also includes a protective cover 13 for the protective container 1, which is located at the mounting hole.
[0058] The outlet 5 for adding detergent additives is equipped with an outlet valve. The outlet valve controls the outlet 5 to open when the container 1 is installed in the mounting part 2 and to seal and close when the container 1 is removed from the mounting part 2. Preferably, the outlet valve is a one-way valve.
[0059] Furthermore, the container 1 includes at least one liquid storage chamber for containing detergent additives, and each liquid storage chamber includes a replenishment port 4 and a discharge port 5.
[0060] In the above scheme, when the replenishment port 4 is located at the mounting hole, it facilitates the user to replenish the detergent additive when the container 1 is not removed or cannot be removed, without disassembling any parts; simply opening the machine door is sufficient. The liquid outlet valve allows for normal detergent additive dispensing after container 1 is installed, while preventing leakage from the outlet 5 when container 1 is removed for replenishment. The protective cover 13 has an opening section 14 for easy opening. The protective cover 13 protects the container 1, preventing dust or liquid from entering and contaminating the detergent additive, and also provides a leak-proof seal. Especially when the replenishment port 4 is located at the mounting hole, the protective cover 13 covers and protects the replenishment port 4.
[0061] Furthermore, the container 1 also includes a removal part 19 for easy removal / installation from the mounting part 2. Preferably, the removal part 19 is a recess provided on the container 1 for easy prying by hand.
[0062] Example 2
[0063] like Figure 4-6 As shown, a drum washing machine includes a front panel 3, a container 1 for holding detergent additives, and a mounting part 2 for supporting the container 1. The mounting part 2 is disposed on the front panel 3, and the container 1 is detachably disposed in the mounting part 2.
[0064] In the aforementioned solutions, the container 1 of existing drum washing machines is mostly installed in a prominent position such as the top or upper left of the washing machine, occupying a large amount of space. Furthermore, due to the narrow space above the drum washing machine, the container 1 is generally elongated, extending longitudinally, making it difficult for users to see the remaining detergent level and to add detergent additives in a timely manner. The elongated structure and complex wiring also make it difficult to easily remove and place the container 1, resulting in significant inconvenience for users adding detergent additives. The container 1 of this invention is detachably installed within the mounting section 2, which is located on the front panel 3. This saves space above the washing machine and allows for a larger container 1. The elongated structure eliminates the need for a long, narrow design, making it easier to replenish detergent additives or remove the container 1 for refilling.
[0065] Furthermore, the front panel includes a clothing inlet 12 for accommodating the machine door, and the container 1 is detachably disposed in the mounting part 2 through the clothing inlet 12. Preferably, the mounting part 2 is disposed on the rear wall of the front panel 3.
[0066] In the above solution, the container 1 is detachably mounted inside the mounting part 2 via the clothing inlet 12, making it more convenient to remove and install the container 1. Even without removing the container 1, it is easy to add detergent additives at the clothing inlet. The mounting part 2 is located on the rear wall of the front panel 3. The container 1 can only be removed from the clothing inlet 12 when the washing machine door is open. When the washing machine door is closed, the container is not visible to the user from the outside, resulting in a better overall appearance and a more aesthetically pleasing design for the drum washing machine. The container 1 can be pulled out and removed from the clothing inlet 12 by sliding it left and right or up and down.
[0067] Furthermore, the clothing dispensing port 12 is provided with an installation hole, and the container 1 is detachably installed in the mounting part 2 through the installation hole.
[0068] Furthermore, the bottom wall of the clothing inlet 12 is provided with an installation hole, and the installation part 2 is located below the installation hole. The container 1 is pulled out from the installation hole and placed into the installation part 2.
[0069] In the above scheme, since there is little space on the left and right sides of the clothes inlet 12 of the front panel 3 of the drum washing machine, the container 1 and the mounting part 2 are generally set on the upper and lower sides of the clothes inlet 12 of the front panel. Since the upper side has high requirements for sealing and the addition of washing additives, it is preferred to set it below the clothes inlet 12.
[0070] Furthermore, the container 1 includes
[0071] The replenishment port 4 for adding detergent additives is preferably located at the mounting hole;
[0072] The outlet 5 for adding detergent additives is equipped with an outlet valve. The outlet valve controls the outlet 5 to open when the container 1 is installed in the mounting part 2 and to seal and close when the container 1 is removed from the mounting part 2. Preferably, the outlet valve is a one-way valve.
[0073] Furthermore, the container 1 includes at least one reservoir for containing detergent additives, each reservoir including a replenishment port 4 and an outlet port 5.
[0074] In the above solution, when the replenishment port 4 is located at the mounting hole, it facilitates the user to replenish the detergent additive when the container 1 is not removed or cannot be removed, without disassembling any parts; simply opening the machine door is sufficient. The liquid outlet valve ensures that detergent additives can be added normally after the container 1 is installed, but prevents leakage from the outlet when the container 1 is removed for replenishment.
[0075] Furthermore, the drum washing machine also includes a dispensing section, which is connected to the washing drum and the liquid outlet 5 respectively to dispense the detergent additive in the container 1 into the washing drum.
[0076] In the above scheme, the dispensing unit is a negative pressure automatic dispensing structure, or the dispensing unit is a suction pump dispensing structure, or the dispensing unit includes a siphon structure.
[0077] Furthermore, the drum washing machine also includes a liquid level detection structure, the liquid level detection structure including...
[0078] A conductive part 7 connected to the circuit is disposed within the mounting part 2;
[0079] The detection unit 6 has one end sealed and inserted into the liquid storage chamber 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 placed in the mounting part 2. When the container 1 is removed from the mounting part 2, it separates from the conductive part 7 to disconnect the circuit.
[0080] Furthermore, the detection part 6 is a conductive probe; the conductive part 7 is a spring-loaded structure connected to a terminal block via a signal line, and the other end of the detection part 6 is pluggably connected to the spring-loaded structure.
[0081] Furthermore, the drum washing machine also includes a protective cover 13 for the protective container 1, the protective cover 13 being disposed at the mounting hole, preferably, the protective cover 13 covering at least the liquid replenishment port 4 when closed.
[0082] Furthermore, the protective cover 13 is provided with an opening part 14 for easy opening of the protective cover 13.
[0083] In the above scheme, a protective cover 13 is provided to protect the container 1, preventing dust or liquid from entering the container 1 and contaminating the detergent additive. It also has a sealing effect to prevent leakage from the container 1. In particular, when the liquid inlet 4 is located at the mounting hole, the protective cover 13 covers the liquid inlet 4 for protection.
[0084] Furthermore, the mounting hole also includes a limiting structure for installing the container 1. Preferably, the limiting structure is a protrusion that protrudes from the side wall of the container 1.
[0085] In the above solution, the limiting structure makes the disassembly or placement of container 1 simpler and more convenient, preventing problems such as misplacement. This avoids issues that could prevent the automatic dispensing of detergent additives or the proper detection of liquid levels.
[0086] Example 3
[0087] like Figure 4-6 As shown, in this embodiment, a drum washing machine includes...
[0088] Front panel 3, the front panel 3 includes a clothing loading port 12 for accommodating the machine door;
[0089] A container 1 for holding detergent additives is disposed inside the clothing inlet 12 on the front panel.
[0090] In the aforementioned solutions, the container 1 of existing drum washing machines is mostly installed in a prominent position such as the top or upper left of the washing machine, occupying a large amount of space. Furthermore, due to the narrow space above the drum washing machine, the container 1 is generally elongated, extending longitudinally, making it difficult for users to see the remaining detergent level and adding detergent additives in a timely manner. The elongated structure and complex wiring also make it difficult to easily remove and place the container 1, resulting in significant inconvenience for users adding detergent additives. The container 1 of this invention is located within the clothing inlet 12 on the front panel 3, saving space above the washing machine. It also increases the size of the container 1, eliminating the elongated structure and making it easier to replenish detergent additives or remove the container 1 for refilling. In addition, the container 1 can only be removed from the clothing inlet 12 when the washing machine door is open; when the washing machine door is closed, the container is not visible from the outside, improving the overall aesthetics and appearance of the drum washing machine. The container 1 can be pulled out from the sides of the clothing inlet 12, either horizontally or vertically.
[0091] Furthermore, the clothing dispensing port 12 is provided with an installation hole, and the container 1 is detachably installed in the installation hole.
[0092] Furthermore, the drum washing machine also includes a protective cover 13 for the protective container 1, the protective cover 13 being disposed at the mounting hole.
[0093] In the above scheme, a protective cover 13 is provided to protect the container 1, preventing dust or liquid from entering the container 1 and contaminating the detergent additive, while also having a sealing effect to prevent leakage from the container 1.
[0094] Furthermore, the shape of the protective cover 13 matches the shape of the mounting hole, and the shape of the container 1 matches the shape of the mounting hole.
[0095] In the above solution, the shape of the protective cover 13 matches the shape of the container 1, allowing for better installation and enhanced protection. The matching shape of the container 1 with the mounting hole makes installation simpler and more convenient, and allows for a compact design to prevent misalignment or installation delays.
[0096] Furthermore, one end of the protective 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.
[0097] In the above scheme, the protective cover 13 can be snapped onto the mounting hole or connected to the mounting hole by threads. In this embodiment, the protective cover 13 is hinged to the mounting hole.
[0098] Furthermore, the protective cover is provided with an opening portion for easy opening.
[0099] In the above-described design, to avoid interfering with the opening and closing of the machine door, the protective cover 13 is on the same surface as or lower than the surface where the clothing inlet 12 is located. In this case, opening the closed protective cover 13 becomes very difficult; it's hard to open it by hand and may require the assistance of a long, thin object, adding inconvenience for the user. Therefore, this invention provides an opening part 14 to facilitate opening the protective cover 13, allowing the user to remove the container 1 to add detergent additives or directly replenish detergent additives into the container 1.
[0100] Furthermore, the mounting hole is located at the bottom of the clothing inlet 12, and the protective cover 13 is located above the mounting hole.
[0101] In the above scheme, there is a lot of space below the front panel 3, the mounting hole is located at the bottom of the clothing inlet 12, and the container self-mounting hole is located below the front panel 3.
[0102] Furthermore, the container 1 is a box-shaped structure with at least a rectangular upper surface, the surface of the clothing inlet 12 with the mounting hole is a plane, and the upper surface of the protective cover 13 is lower than or parallel to this plane.
[0103] In the above scheme, the upper surface of the protective 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 machine door.
[0104] Furthermore, the protective cover 13 is provided with an opening part 14 for easy opening of the protective cover 13. Preferably, the opening part 14 is a notch on the protective cover 13 that is easy to pry open by hand. More preferably, the notch is a notch on the other movable end of the protective cover 13.
[0105] Furthermore, the mounting hole includes a limiting part for mounting the limiting container 1.
[0106] In the above solution, the limiting part makes it easier and more convenient to pick up and put down container 1, preventing problems such as misplacement. This avoids the inability to automatically add detergent additives or detect liquid levels properly due to misplacement.
[0107] Example 4
[0108] like Figure 7-9 As shown in the figure, in this embodiment, the washing machine also includes at least one set of liquid level detection structures for detecting the liquid level in the container 1.
[0109] In the above solutions, because container 1 is generally connected to various pipes, it is difficult to remove container 1 for operations such as replenishing liquid, requiring professional maintenance personnel. This causes great inconvenience to users when replenishing detergent additives. The container 1 described in this invention is removable and housed within the installation part 2, facilitating removal for replenishment and maintenance. Since the automatic detergent additive dispensing device automatically adds detergent additives to the washing machine, and users cannot visually see the dosage in container 1, a liquid level reminder, especially a minimum liquid level reminder, is particularly necessary. However, for ordinary automatic detergent additive dispensing devices, real-time monitoring of the detergent additive amount is not essential. It is sufficient to issue an alarm and execute relevant procedures when the detergent additive level falls below the minimum level to avoid problems such as incomplete or unclean washing caused by insufficient detergent additive dosage. The container 1 described in this invention is removably disposed within the mounting part 2 for replenishing detergent additives; the liquid level detection structure can be used for liquid level detection of the removable container 1 disposed within the mounting part 2. After the container 1 is removed for replenishment of detergent additives, the liquid level can continue to be detected sensitively and accurately after the container 1 is placed back in place.
[0110] 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. When the container 1 is removed from the mounting part 2, it separates from the conductive part 7 and disconnects the circuit.
[0111] In the above scheme, the detection unit 6 is used to detect the liquid level, and the conductive unit 7 is used to connect the circuit. Because the container 1 is removable and placed inside the mounting part 2, when the container 1 is removed, the detection unit 6 is removed along with the container 1, and the detection unit 6 leaves the conductive unit 7, the circuit is broken, and liquid level detection cannot be performed; when the container 1 is placed back into the container mounting part 2, the detection unit 6 and the conductive unit 7 re-contact, the circuit is connected, and liquid level detection can continue.
[0112] Furthermore, the liquid level detection structure includes two detection units 6. When the detergent additive in the container is in contact with both detection units 6, the two detection units 6 are connected through the detergent additive, and the liquid level detection structure forms a circuit path, and the detection units 6 detect that there is enough detergent additive. Conversely, if the detergent additive in the container is not in contact with at least one detection unit 6, the circuit between the two detection units 6 is broken, and the liquid level needs to be replenished with detergent additive.
[0113] In the above scheme, the two detection units 6 are electrically connected to the control module through conductive parts 7. When the two detection units 6 are connected, the entire signal circuit is connected and can transmit signals; otherwise, the entire signal circuit is disconnected and cannot transmit signals. Specifically, the two detection units 6 are connected when both are in contact with the detergent additive in the detergent storage chamber. Because the detergent additive is conductive, when both detection units 6 are in contact with the detergent additive, the detergent additive acts as a wire connecting the two detection units 6.
[0114] Furthermore, the liquid level detection structure also includes a fixing part 9, and the detection part 6 is sealed and wrapped inside the fixing part 9, with both ends extending 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 threadedly connected to the container 1.
[0115] In the above scheme, the fixing part 9 can be made of insulating material, and the fixing part 9 inserts the detection part 6 into the container. When the fixing part 9 is not inserted, its function is to seal and fix the detection part 6, making it easier to seal and connect with the container 1.
[0116] Furthermore, one end of the detection part 6 is detachably and sealed into the container 1 through the fixing part 9. The fixing part 9 is made of insulating material and 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.
[0117] In the above scheme, the probe 6 of the liquid level detection structure of the present invention is inserted into the container 1 from the bottom, which makes it easier to detect whether the detergent additive in the container is sufficient. At the same time, since the outlet 5 is also located at the bottom, it is easy to install without adding other structures, thus saving costs. In this embodiment, the fixing part 9 is partially inserted into the container. At this time, the fixing part 9 not only fixes the probe 6, making it easier to seal and connect with the container 1, but also increases 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 sufficient detergent additive in the container at the minimum liquid level.
[0118] Furthermore, when the detergent additive level in the container is higher than the fixing part 9, the two detection parts 6 are connected, forming a circuit in the liquid level detection structure, and the detection parts detect that there is sufficient detergent additive. Conversely, if the detergent additive level in the container is lower than the fixing part 9, the circuit between the two detection parts 6 is broken, and the liquid level is low, requiring the addition of detergent additive. 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 parts 6 do 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 do the detection parts 6 contact and connect with the detergent additive in the container 1.
[0119] Furthermore, the liquid level detection structure also includes a sealing structure 10 between the sealing and fixing part 9 and the container 1, which is disposed between the container 1 and the fixing part 9. Preferably, the sealing part is a sealing ring.
[0120] 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 is 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 dispensing amount. Or the detergent additive that flows out accidentally flows into other substances in the washing machine cabinet, causing waste and contaminating or corroding other parts. Therefore, the sealing at the detection hole is very important, and it is imperative to set up a sealing structure 10 for sealing.
[0121] Furthermore, the fixing part 9 includes a sealing protrusion 11 protruding from its side wall, and the sealing structure 10 is disposed between the bottom of the container 1 and the sealing protrusion 11.
[0122] In the above solution, the fixing part 9 includes a sealing protrusion 11 protruding from its side wall. The sealing protrusion 11 is annularly protruding from the side wall of the fixing part 9, serving both as an auxiliary seal and as a limiting and fixing part 9. The sealing protrusion 11 also facilitates installation.

[0124] This embodiment serves as a further limitation on all the foregoing embodiments, such as Figure 7-9 As shown in the figure, this embodiment discloses a washing machine, which includes an automatic detergent additive dispensing device. The automatic detergent additive dispensing device includes a container 1 for holding detergent additives and a mounting part 2 for supporting the container, wherein the container 1 is removably disposed within the mounting part 2.
[0125] The container 1 includes two liquid storage chambers. One chamber contains detergent for washing clothes and is called the detergent storage chamber. The other chamber contains fabric softener and is called the fabric softener storage chamber. Each liquid storage chamber includes a replenishment port 4 and a discharge port 5. The discharge port 5 is located at the bottom of the liquid storage chamber 1. The automatic detergent additive dispensing device also includes an automatic dispensing structure, which can automatically dispense the detergent additive in the container 1 from the discharge port 5 into the mounting part 2. The mounting part 2 is connected to the washing drum and has a water inlet and a water outlet. Water enters through the water inlet to flush the detergent additive dispensed from the container 1 into the washing drum; or the automatic dispensing structure connects the discharge port 5 and the washing drum to automatically dispense the detergent additive in the container 1 into the washing drum.
[0126] The automatic detergent additive dispensing device also includes two sets of liquid level detection structures, with one set for each storage chamber. Each liquid level detection structure includes a probe 6, which is a conductive probe, and an insulated fixing part 9. The probe is wrapped around the fixing part 9, with both ends extending out of the fixing part 9. It also includes a conductive part 7, which is a spring-loaded structure connected to a terminal block 8 via a signal line. The other end of the probe 6 is detachably and sealed into the spring-loaded structure. One end of the conductive probe and part of the fixing part 9 are detachably and sealed into the storage chamber. The height to which the fixing part 9 is inserted into the bottom of the storage chamber is the minimum liquid level. The liquid level detection structure is used to detect whether there is sufficient detergent additive in the storage chamber. The other end of the conductive probe is inserted into the spring-loaded structure, and the circuit connected to the spring-loaded structure is conductive.
