[0027] Please refer to Figure 1 , Figure 2 as well as Figures 10 to 12As shown, in the embodiment illustrated in the present application, the dispensing device 100 for liquid detergent comprises a first housing 1, a cover 2 mounted on the first housing 1, a second housing 3 connected to the first housing 1, a back plate 4 mounted on the back of the first housing 1 and fixed to the first housing 1, a cover 6 mounted on the second housing 3, and a dispensing control device 7 at least partially mounted in the second housing 3. The dispensing device 100 has a storage chamber 10 and a dispensing chamber 310, the storage chamber 10 is located between the first housing 1 and the back plate 4, and the dispensing chamber 310 is located between the second housing 3 and the cover 6. In the embodiment illustrated in the present application, the back plate 4 is assembled and surrounded with the first housing 1 to form the storage chamber 10. The cover 2 and the back plate 4 are located on two sides (e.g., the front and back sides) of the first housing 1.

[0028] The first housing 1 includes a main body 11 and an injection portion 12. The injection portion 12 and the second housing 3 are located at two ends (e.g., the top and the bottom) of the main body 11. The liquid detergent dispensing device 100 includes a main housing 8, and the main housing 8 includes a first housing 1 and a second housing 3, wherein the second housing 3 is integrally formed with the first housing 1. Through this design, on the one hand, the number of molds is reduced, saving costs; on the other hand, the integrally formed second housing 3 and first housing 1 avoid the sealing problem caused by the assembly of the two in the related art, thereby improving the reliability of the product.

[0029] Please refer to Figures 2 to 7 As shown, the injection portion 12 is provided with a recessed portion 121 that is recessed relative to the main body 11 toward the storage cavity 10, a plurality of bosses 122 that protrude from the recessed portion 121 in a direction away from the back plate 4, side walls 123 located on both sides of the recessed portion 121, and a block 124 close to the main body 11. In the embodiment illustrated in the present application, the recessed portion 121 is a whole. There are three bosses 122 and they are arranged at intervals, and each boss 122 is provided with a detergent feeding port 1221 that is connected to the storage cavity 10. With such a design, when the cover body 2 is opened, the three detergent feeding ports 1221 can be exposed, realizing the addition of three detergents, thereby improving the convenience of use. In the embodiment illustrated in the present application, the shape of the detergent feeding port 1221 is circular. Of course, in other embodiments, it can also be designed into other shapes, such as polygons.

[0030] In addition, in order to achieve a better sealing effect, the liquid detergent dispensing device 100 is further provided with a sealing gasket 125, which is pressed between the boss 122 and the cover body 2, and the sealing gasket 125 can separate the three detergent feeding ports 1221. With such a design, when different detergents are added from these detergent feeding ports 1221, even if the added detergents flow to the outside of the detergent feeding ports 1221, these detergents are not easy to enter other detergent feeding ports 1221, which avoids the mixing of the detergents to a certain extent.

[0031] Please refer to Figures 2 to 7 as well as Fig.12 As shown, the cover body 2 is rotatably mounted on the injection part 12 so as to be able to open or close the detergent feeding port 1221.

Of course, in other embodiments, the hook 221 and the slot 1241 can also be exchanged, that is, the hook 221 is arranged on the injection part 12, and the slot 1241 is arranged on the cover body 2. The number of the hooks 221 and the slots 1241 can be flexibly designed as required.

[0032] During installation, the back plate 4 is fixed to the inner wall plate 200 of the dishwasher. When the user opens the door of the dishwasher, the inner wall plate 200 changes from a vertical direction to a horizontal direction, and accordingly, the cover body 2 changes from an original vertical direction to a horizontal direction, so that it is more convenient for the user to open the cover body 2 to add detergent, and the detergent is not easy to spill from the detergent feeding port 1221.

[0033] Please refer to Figure 2 and Figure 4 As shown, the cover body 2 also includes an inner surface 210 facing the injection portion 12 when the cover body 2 is closed, a plurality of first reinforcing ribs 23 located on the inner surface 210, and an annular groove 24 accommodating at least part of the sealing gasket 125. In the embodiment illustrated in the present application, the first reinforcing ribs 23 are in a lattice shape to improve the structural strength of the cover body 2 and avoid deformation and breakage. When the cover body 2 is closed, the sealing gasket 125 is pressed between the boss 122 and the inner surface 210 of the cover body 2 to achieve complete sealing of the detergent feeding port 1221.

[0034] In the embodiment illustrated in the present application, the cover body 2 is a whole. Of course, in other embodiments, the cover body 2 may also be two or more (not shown). In this case, one cover body 2 may correspond to one or more detergent feeding ports 1221, and each cover body 2 closes at least one detergent feeding port 1221 when in the closed state. The opening directions of these cover bodies 2 may be the same (for example, all are clockwise or all are counterclockwise) or different (for example, one part of the cover body is clockwise, and the other part of the cover body is counterclockwise, and vice versa).

[0035] Please refer to Fig.10 and Fig.11 As shown, in the embodiment illustrated in the present application, the first shell 1 includes a top plate 13 and a side plate 14, the side plate 14 of the first shell 1 is connected between the top plate 13 and the back plate 4, at least a portion of the back plate 4 on one side away from the first shell 1 forms a mounting surface that matches the dishwasher, and the top plate 13 and the side plate 14 surround an opening 15. The top plate 13 of the first shell 1 includes an injection portion 12 and a main body portion 11 connected to the injection portion 12. The back plate 4 is installed on the first shell 1, and the back plate 4 closes the opening 15 to form a storage cavity 10. The back plate 4 is fixed to the first shell 1 by welding or bonding. The storage cavity 10 includes a plurality of sub-cavities separated from each other. In the embodiment illustrated in the present application, the first shell 1 includes a plurality of partitions 16 connected to the top plate 13. Specifically, the sub-cavity includes a first sub-cavity 101, a second sub-cavity 102 and a third sub-cavity 103, wherein the first sub-cavity 101, the second sub-cavity 102 and the third sub-cavity 103 are separated from each other by a partition 16 and are respectively connected to respective detergent feeding ports 1221. The first sub-cavity 101, the second sub-cavity 102 and the third sub-cavity 103 can be used to accommodate detergents of the same type or different types. For example, the second sub-cavity 102 has the largest accommodation space, which can be used to store cleaning agents that are consumed quickly, and the first sub-cavity 101 and the third sub-cavity 103 have smaller accommodation spaces, which can be used to store bleaching agents and brighteners that are consumed slowly, respectively.

[0036] In the embodiment shown in the figure of the present application, the top plate 13 is provided with a convex column 131 protruding into the storage cavity 10, and the through hole 110 is provided on the convex column 131, and the through hole 110 passes through the top plate 13 and the back plate 4. There are at least two convex columns 131 and they are located in the same sub-cavity (for example, the second sub-cavity 102). Of course, in other embodiments, the through hole 110 can also be provided on at least one partition 16, so that there is no need to provide an additional convex column 131, which reduces the complexity of the mold and facilitates the molding of the first shell 1.

[0037] The second housing 3 has a dispensing chamber 310 for dispensing liquid detergent (see Figure 5 As shown) and the assembly port 313 connected to the distribution chamber 310 (please refer to Fig.12 As shown). The volume of the storage chamber 10 is larger than the volume of the distribution chamber 310 to avoid adding detergent too frequently. In the embodiment shown in the figure of the present application, the second shell 3 is provided with a plurality of cylindrical portions 31 and a plurality of second reinforcing ribs 32 connected to the cylindrical portions 31. For details, please refer to Figures 9 to 12 as well as Fig.14 As shown, in the embodiment illustrated in the present application, there are six cylindrical portions 31, which include a first cylindrical portion 311 and a second cylindrical portion 312 that is shorter than the first cylindrical portion 311. These cylindrical portions 31 form a group of units in pairs, and each group of units includes a first cylindrical portion 311 and a second cylindrical portion 312. Each group of units is provided with a distribution chamber 310. Specifically, the distribution chamber 310 includes a first cavity 3101 formed in the first cylindrical portion 311 and a second cavity 3102 formed in the second cylindrical portion 312. The first cavity 3101 is connected to the second cavity 3102. The first cavity 3101 and the second cavity 3102 are both formed with an assembly port 313 located at the bottom.

[0038] Please refer to Figure 5 As shown, the second reinforcing ribs 32 on one side are located in the axial direction of the cylindrical portion 31. Specifically, there are six second reinforcing ribs 32. Each second reinforcing rib 32 extends outward from the arc of the cylindrical portion 31 until it is flush with the outer shell of the main body 11. The material of the second reinforcing rib 32 can be the same as that of the second shell 3, and the second reinforcing rib 32 and the second shell 3 are integrally formed. Please refer to Fig.11 As shown, the second reinforcing rib 32 on the other side is perpendicular to the axis direction of the cylindrical portion 31. Specifically, there are two second reinforcing ribs 32, and they are distributed on two different surfaces. This arrangement improves the structural strength of the cylindrical portion 31. In the embodiment illustrated in the present application, the axis of the protruding column 131 is perpendicular to the axis of the cylindrical portion 31.

[0039] The cover 6 closes the assembly opening 313, and the cover 6 is provided with a dispensing opening 61 for flowing out the liquid detergent. The second housing 3 and the cover 6 can be sealed by glue or welding. The dispensing control device 7 is at least partially accommodated in the dispensing chamber 310, and the dispensing chamber 310 is connected or isolated from the storage chamber 10 through the dispensing control device 7.

[0040] The dispensing control device 7 includes a valve member 72 that is controlled by an electric signal to move in the dispensing chamber 310. When the valve member 72 is located at a first position, the valve member 72 closes the dispensing opening 61, and the dispensing opening 61 is isolated from the dispensing chamber 310, so that the dispensing chamber 310 can store the liquid detergent flowing in from the storage chamber 10. When the valve member 72 is located at a second position, the valve member 72 opens the dispensing opening 61, and the dispensing opening 61 is connected to the dispensing chamber 310, so that the liquid detergent in the dispensing chamber 310 flows out. Please refer to Fig.12As shown, the valve member 72 is contained in the second cavity 3102. The valve member 72 may be a solenoid pulse valve driven by an instantaneous pulse signal. Of course, the valve member 72 may also be a solenoid valve that is normally powered.

[0041] In some embodiments, the valve member 72 is schematically illustrated as an electromagnetic pulse valve. In addition to the valve member 72, the distribution control device 7 may also include components such as a coil and a magnet housed in the second cavity 3102. When the coil is energized, a magnetic field that excites the valve member 72 to move. The magnetic force generated by the magnetic field can drive the valve member 72 to move along the axis of the second cavity 3102. When the valve member 72 moves to the first position, it can be adsorbed by a fixed magnet to be positioned in the first position. When the valve member 72 moves to the second position, it can be adsorbed by another fixed magnet to be positioned in the second position. Thereby, the distribution opening 61 is opened or closed by the valve member 72.

[0042] The distribution control device 7 further includes a floating ball 71 which is accommodated in the first cavity 3101 and is movable along the axial direction of the first cavity 3101 .

[0043] The dispensing control device 7 comprises a first working state (eg a detergent filling state, which corresponds to the first position) and a second working state (eg a detergent outflow state, which corresponds to the second position).

[0044] In the first working state, the valve member 72 of the distribution control device 7 moves to the first position, and the distribution control device 7 closes the distribution opening 61. Initially, the distribution control device 7 connects the storage chamber 10 and the distribution chamber 310, and the detergent can further fill the distribution chamber 310 of the second shell 3 from the opening 3111 at the top of the first cylindrical portion 311. The detergent flows from the storage chamber 10 into the distribution chamber 310. When the detergent in the second shell 3 is completely filled, the float 71 is subjected to the upward buoyancy and moves to the top of the first cavity 3101, and separates the storage chamber 10 from the distribution chamber 310. Due to the buoyancy, the float 71 completely supports the opening 3111 at the top of the first cylindrical portion 311. At this time, the detergent can no longer be injected into the second shell 3, and the distribution chamber 310 stores a certain amount of detergent.

[0045] In the second working state, the valve member 72 of the distribution control device 7 moves to the second position, the distribution control device 7 opens the distribution opening 61, the detergent flows out from the distribution opening 61, and the float 71 moves downward again due to gravity and the pressure of the detergent above it, and finally stops at the bottom end of the first cylindrical portion 311, and a certain amount of detergent stored in the distribution chamber 310 all flows out from the distribution opening 61, thereby realizing quantitative distribution.

[0046] Please refer to Figure 8As shown, in one embodiment of the present application, the inner wall plate 200 of the dishwasher is provided with an opening 201 in a substantially rectangular shape, a retaining piece 202 located at the edge of the opening 201, and a connecting block 203 installed in the opening 201 and fixed by the retaining piece 202. The connecting block 203 is substantially rectangular and is provided with a mounting hole 2031. Specifically, the connecting block 203 includes a mounting portion 2032 and a flange portion 2033 for abutting against the inner wall plate 200, and the mounting hole 2031 is provided in the mounting portion 2032. The size of the mounting portion 2032 is designed to pass through the opening 201, and the mounting portion 2032 of the connecting block 203 is fixed from Figure 8 The lower side of the first housing 1 moves along the axial direction of the opening 201, and the size of the flange portion 2033 is designed to be unable to pass through the opening 201, so that the flange portion 2033 can limit the direction of the connection block 203 moving upward. The first housing 1 is provided with a through hole 110 corresponding to the mounting hole 2031. The through hole 110 is not connected to the storage cavity 10, and the through hole can accommodate a part of the threaded fixing member 5. During assembly, the liquid detergent dispensing device 100 is placed in the inner tank of the dishwasher, next to the inner wall plate 200, the second housing 3 faces downward, the storage cavity 10 faces upward, and the connection block 203 is placed on the other side of the inner wall plate 200 in the dishwasher. With the help of the threaded fixing member 5 passing through the through hole 110 and tightening the threaded fixing member 5 in the mounting hole 2031, the liquid detergent dispensing device 100 can be installed on the inner wall plate 200. The threaded fixing member 5 includes two screws 51 (for example, plastic screws), and the screws 51 are detachably installed in the mounting hole 2031. The assembly formed by the liquid detergent dispensing device 100 and the connecting block 203 is a liquid detergent dispensing device assembly.

[0047] Further, refer to Fig.12 As shown, the threaded fixing member 5 further includes two bolts 52, and the lower end of the second housing 3 is provided with two bolt holes 300 that match the bolts 52. The bolts 52 (e.g., plastic bolts) that pass through the inner wall plate 200 of the dishwasher can be connected with nuts 302 (e.g., plastic nuts) located on the inner wall plate 200 to further fix the liquid detergent dispensing device 100.

[0048] Of course, in other implementations, please refer to Fig.13As shown, the opening 201 can also be a smaller opening to improve the sealing. In the embodiment illustrated in the present application, the opening is two and circular; accordingly, the connecting block 203 is also two and cylindrical (e.g., cylindrical), and is installed and fixed in the opening. During assembly, by means of a threaded fixing 5 (e.g., a plastic screw) passing through the perforation 110, and tightening the threaded fixing 5 in the connecting block 203, the connecting block 203 can be located on different sides of the inner wall plate 200 with the dispensing device 100, and the connecting block 203 can be a nut matched with the threaded fixing 5, so that the dispensing device 100 of the liquid detergent can be installed on the inner wall plate 200. In order to further improve the sealing, a sealing gasket 206 matched with the threaded fixing 5 can also be installed on both sides of the inner wall plate 200. With such a design, it is not necessary to open too large an opening on the inner wall plate 200, and the sealing effect can be enhanced to a certain extent. By opening two small openings on the inner wall plate 200 to realize the connection function, the cost is low.

[0049] Compared with the related art, the present application detachably mounts the liquid detergent dispensing device 100 on the inner wall plate 200 through a threaded fastener 5. When the liquid detergent dispensing device 100 needs to be cleaned, it can be easily removed, thereby improving the user experience.
