Description

Technical Field

[0001] This invention relates to a garment processing device in the field of household appliance technology, and more specifically, to an additive dispensing device used in garment processing equipment. Background Technology

[0002] Washing machines use water, fabric softener, and mechanical operation to wash and care for clothes, achieving the desired washing and care results. With the increasing automation of washing machines, related technologies include automatic detergent dispensing. In these machines, an additive dispenser containing detergent and / or fabric softener is connected to the water inlet pipe, allowing water to flush the detergent and / or fabric softener from the dispenser into the washing tub.

[0003] Chinese Patent Application No. 201610797034.7 discloses a detergent dispensing device for a washing machine and a washing machine having the same. The detergent dispensing device includes a storage cavity, which defines a special detergent box placement slot. The special detergent box placement slot is provided with a first pin and a second pin for piercing the special detergent box. The first pin has a water inlet hole, and the second pin has a water outlet hole. Both the first pin and the second pin are configured to allow the water inlet hole and the water outlet hole to communicate with the internal space of the special detergent box after the pin is inserted into the special detergent box at its end.

[0004] Existing additive dispensing devices generally have a docking structure, such as the pin structure described in the aforementioned patent documents, installed inside the water tank of the additive dispensing device. This docking structure connects the outlet of the dispensing cavity inside the water tank with the inlet of the water channel integrated on the water tank.

[0005] However, the above-mentioned additive dispensing devices generally have the following problems:

[0006] Since the dispensing chamber is usually located on the drawer section of the water box that can be pulled outwards, the dispensing process can easily cause leakage of liquids such as additives at the connection structure. Therefore, it is necessary to introduce rinsing water into the installation chamber inside the water box to rinse the inside of the chamber. After rinsing, the rinsing water in the installation chamber inside the water box needs to be drained out.

[0007] Although existing dispensing devices generally have an outlet at the bottom of the water tank to discharge the rinsing water, some dispensing devices do not have an outlet on the bottom wall of the water tank. In particular, when the dispensing device is set up with multiple relatively independent modules and the additives of the auxiliary dispensing modules are dispensed through the main dispensing module, the lack of an outlet in the auxiliary dispensing modules will result in the water tank of the auxiliary dispensing modules not having a normally open outlet on the bottom wall, and the water tank cannot discharge water.

[0008] Therefore, how to design an additive dispensing device to ensure that the water box without a normally open outlet on the bottom wall can normally discharge the rinsing water has become an urgent technical problem to be solved.

[0009] In view of this, the present invention is hereby proposed. Summary of the Invention

[0010] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an additive dispensing module, an additive dispensing device and a clothing treatment equipment. By adding a drainage structure to the dispensing module, the additives and / or rinsing water in the water box of the dispensing module can be discharged.

[0011] To achieve the above-mentioned objectives, the specific solution adopted by the present invention is as follows:

[0012] An additive dispensing module includes a water box with a hollow interior forming an installation cavity. A drain connector is provided inside the installation cavity of the water box, one end of which is connected to the lowest point of the installation cavity of the water box, and the other end is connected to the outside of the water box through a water outlet provided on the water box.

[0013] Furthermore, the drain connector extends vertically inside the installation cavity, with its lower end connected to the lowest point of the bottom wall of the installation cavity and its upper end connected to the water outlet channel integrated on the top cover of the water box.

[0014] Furthermore, the bottom wall of the mounting cavity is provided with a downwardly recessed groove, into which the drain connector extends, and the lower end of the drain connector is positioned close to the bottom of the groove.

[0015] Furthermore, the top wall of the water box is formed by a cover, the water outlet is integrated on the cover, and the top of the drain connector is connected to the cover.

[0016] Preferably, the drain connector is integrated with the top cover of the water box.

[0017] Furthermore, the outer wall of the drain connector is provided with multiple reinforcing ribs that are arranged axially at intervals, protrude radially, and extend along the axial direction. The upper end of each reinforcing rib is connected to the top cover that forms the top wall of the water box.

[0018] Furthermore, a suction structure is provided or connected to the water outlet path. The suction structure is used to generate suction force at the inlet of the water outlet path and draw the water in the installation cavity out along the water outlet path.

[0019] Furthermore, the water box has a retractable drawer inside its mounting cavity. The drawer has at least one dispensing cavity for storing additives. The outlet of the dispensing cavity is connected to the dispensing water channel on the water box via a docking structure. The water box has a rinsing water channel with its rinsing outlet facing into the mounting cavity for rinsing the additives that drip from the docking structure into the mounting cavity.

[0020] Furthermore, the drain connector and the flushing outlet of the flushing water path are respectively located on the left and right sides of the docking structure; the bottom wall of the mounting cavity is inclined downward from the flushing outlet connecting side to the drain connector connecting side.

[0021] Furthermore, a downwardly recessed groove is provided on the bottom wall of the mounting cavity below the docking structure, and the drain connector extends into the groove, with the lower end of the drain connector being close to the bottom of the groove in terms of the gap.

[0022] A further preferred embodiment is that the mounting cavity is a chamber structure with no openings in the bottom wall.

[0023] Furthermore, the inlet end of the outlet water path is connected to the drain connector and the flushing water path via a tee;

[0024] In a further preferred embodiment, the upper end of the vertically extending drain connector is connected to the first opening of the tee facing downwards;

[0025] The inlet of the flushing water passage is connected to an external water source, and the outlet is connected to the second opening of the T-junction. The middle of the flushing water passage is provided with a flushing outlet facing the docking structure.

[0026] The inlet end of the water outlet is connected to the third opening of the tee, and the outlet end is connected to the outside of the dispensing device.

[0027] Further preferably, the second opening and the third opening are coaxially arranged; the diameter of the third opening is smaller than the diameter of the second opening and smaller than the diameter of the flushing water pipe, and the third opening is set higher than the flushing outlet.

[0028] The present invention also provides an additive dispensing device, which includes a plurality of dispensing modules, at least one of which is an auxiliary dispensing module composed of any of the additive dispensing modules described above.

[0029] Furthermore, the additive dispensing device is also equipped with a main additive dispensing device, which has a water supply path. The inlet end of the water supply path is connected to an external water source, and the outlet end is connected to the inlet end of the flushing path on the auxiliary dispensing module via an interactive water path. The outlet end of the water path on the auxiliary dispensing module is connected to the outlet on the main dispensing module via another interactive water path.

[0030] The present invention also provides a clothing processing device, which is equipped with the additive dispensing device described above. The water inlet structure of the clothing processing device is connected to the water inlet end of the water supply circuit of the main dispensing module, and the water outlet of the main dispensing module is connected to the water tank or drain pipe of the clothing processing device.

[0031] The present invention also provides a garment processing device, which is equipped with any of the above-mentioned additive dispensing modules. The water inlet structure of the garment processing device is connected to the water inlet end of the rinsing water path of the additive dispensing module, and the water outlet end of the water outlet path is connected to the water tank or drain pipe of the garment processing device.

[0032] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0033] By installing a drain connector on the additive dispensing module, the installation cavity of the water box is connected to the water outlet channel integrated on the water box, thereby achieving the effect of draining dripping liquid and rinsing water from the installation cavity using the water outlet channel on the dispensing module. At the same time, through the above-mentioned arrangement, the installation cavity inside the water box of the additive dispensing module, which is not supplied with inlet water, can be drained directly using the drain connector, thus ensuring the smooth drainage of rinsing water from the installation cavity and effectively preventing the generation of odors inside the water box.

[0048] Example 1

[0049] like Figures 1 to 6As shown, this embodiment provides an additive dispensing device, which includes: two or more dispensing modules 100; each dispensing module has at least one dispensing chamber 9. The dispensing chamber 9 can be an open water-passing chamber for dispensing after mixing with detergent, etc., or a closed chamber for storing detergent, etc., and dispensing after extraction. In this embodiment, the dispensing chamber 9 is described as a hollow chamber of a sealed container composed of a liquid storage box 12 in the shape of an ink cartridge, but the dispensing chamber 9 in this invention is not limited to the above structure. In this embodiment, each dispensing chamber 9 is connected to at least one dispensing water path 4, and each dispensing water path 4 is integrated into its corresponding dispensing module 100, so as to extract the additive in the dispensing chamber 9 using the dispensing water path, thereby achieving the effect of dispensing the additive in the dispensing chamber 9 accordingly. In this embodiment, the additive dispensing device further includes an interactive water path 103, the two ends of which are respectively connected to water paths integrated on different dispensing modules 100. The water paths include, but are not limited to, dispensing water path 4, so that the additive extracted by the dispensing water path 4 on the dispensing module 100 can be dispensed to the outside using other dispensing modules.

[0050] The above-mentioned configuration allows for an expansion of the additive dispensing device, which not only increases the variety of additives that can be dispensed, but also enables the same type of additive to be stored and dispensed separately on different dispensing modules, thereby significantly increasing the storage capacity of additives.

[0051] like Figures 1 to 6 As shown, in this embodiment, one of the additive dispensing modules 100 is the main dispensing module 101. The main dispensing module 101 is composed of a first water box 21. The first water box 21 has at least one outlet 11 that provides water flow to the outside. The outlet of the dispensing water path 4 provided on the main dispensing module 101 is connected to at least one outlet 11. The other dispensing module 100 is an auxiliary dispensing module 102. Each dispensing water path 4 of the auxiliary dispensing module 102 is integrated on the main body of the auxiliary dispensing module 102, and each dispensing water path 4 of the auxiliary dispensing module 102 is connected to the outlet 11 provided on the first water box 21 of the main dispensing module 101 via an interactive water path 103.

[0052] In this embodiment, the main dispensing module 101 and the auxiliary dispensing module 102 each have a main body, and the main bodies formed by the two are independently set. The main bodies of the main dispensing module 101 and the auxiliary dispensing module 102 are respectively composed of a first water box 21 and a second water box 22, and the two are independently set and connected by an interactive waterway 103.

[0053] With the above settings, different dispensing modules can share a set of outlets 11 to dispense additives, which not only enriches the types of additives but also simplifies the structure of the dispensing device. At the same time, since the outlets 11 are only set on the main dispensing module 101, the auxiliary dispensing module 102 does not need to be equipped with other accessories, which increases the proportion of the dispensing chamber 9 set on the auxiliary dispensing module 102, thereby increasing the additive volume of the auxiliary dispensing module 102.

[0054] In this embodiment, each interactive water path 103 is connected to the corresponding water outlet 11 via the same or different water paths provided on the first water box 21 of the main dispensing module 101, so that the dispensing water path 4 on the auxiliary dispensing module 102 can realize a single or multiple forms of water dispensing. The water path connected to the corresponding water outlet 11 can be the dispensing water path 4 provided on the main dispensing module 101, or it can be the water outlet connection water path 17 integrated on the main dispensing module 101, which is not connected to the dispensing cavity 9 provided on the main dispensing module 101, but is connected to the water outlet 11.

[0055] like Figures 1 to 6 As shown in the accompanying drawings of this embodiment, only the following example is used for illustration: the main dispensing module 101 is provided with multiple dispensing water channels 4, and each dispensing water channel 4 provided on the auxiliary dispensing module 102 is connected to the different dispensing water channels 4 provided on the main dispensing module 101. The outlet of each dispensing water channel 4 provided on the main dispensing module 1 is connected to one or a combination of different outlets 11 provided on the main dispensing module 101 through the control valve 18.

[0056] In this embodiment, the auxiliary dispensing module 102 includes a second water box 22. The hollow cavity inside the second water box 22 forms an installation cavity 10. The installation cavity 10 is provided with a drawer 2 that can be pulled outwards, and the drawer 2 is provided with at least one dispensing cavity 9. All dispensing water channels 4 provided on the auxiliary dispensing module 102 are integrated on the second water box 22. Preferably, the top of the second water box 22 of the auxiliary dispensing module 102 is formed by an upper cover 3, which is composed of two interlocking cover plates, namely an upper cover plate 31 and a lower cover plate 32. There are protruding ribs between the two cover plates 31 and 32, which divide the space between the two cover plates 31 and 32 into different water channels. Similarly, the main dispensing module 101 includes a first water box 21. The top wall of the first water box 21 is formed by another upper cover 3, and the water channel structures such as the dispensing water channels 4 mentioned on the main dispensing module 101 are also integrated on the upper cover 3 that forms the top wall of the first water box 21.

[0057] In this embodiment, the outlets of the dispensing water channels 4 on the auxiliary dispensing module 102 are connected to one or more interactive water channels 103, so that the additives contained in the dispensing chamber 9 of the auxiliary dispensing module 102 can only flow to the water channels on the main dispensing module 101 through one or more interactive water channels 103, either selected or combined simultaneously. The accompanying drawings of this embodiment only illustrate the example of each dispensing water channel 4 on the auxiliary dispensing module 102 being connected to a different interactive water channel 103, but the additive dispensing device of this invention is not limited to the drawings and can be configured in other ways.

[0058] In this embodiment, the upper cover 3 of the second water tank 22 with the dispensing module 102 is integrated with a dispensing water channel 4. The inlet of the dispensing water channel 4 is connected to the outlet of the dispensing cavity 9 formed inside the liquid storage box 12 installed on the drawer 2 via a docking structure 8 between the second water tank 22 and the drawer 2. This allows the outlet of the dispensing cavity 9 to connect with the inlet of the corresponding dispensing water channel 4 after the drawer 2 is installed on the water tank 1. The docking structure 8 in this embodiment can be any existing structure, as long as it connects the dispensing cavity 9 on the drawer 2 with the inlet of the dispensing water channel 4 on the water tank 1.

[0059] In this embodiment, the dispensing chamber 9 constitutes a liquid storage structure for storing additives, or a chamber structure for dispensing additives with incoming water; the dispensing chamber 9 can be composed of a chamber structure fixedly installed on the drawer portion 2 inside the water box 1, or as... Figures 1 to 5 As shown, the liquid storage box 12 is composed of a hollow chamber inside, which is made up of an independent box body that is detachably assembled on the inner drawer part 2 of the water box 1.

[0060] Example 2

[0061] This embodiment is based on the above embodiment one and has the following distinguishing technical features:

[0062] In this embodiment, the water tanks 1 of the two additive dispensing modules 100 in the additive dispensing device are respectively provided with water outlets 11 that discharge additives and / or water. The dispensing water path 4 on one of the two additive dispensing modules 100 is connected to the water path on the other additive dispensing module 100 via an interactive water path 103. At the same time, the dispensing water path 4 on both dispensing modules 100 is also connected to the water outlet 11 on their respective additive dispensing modules 100, so as to achieve the effect that the additives in the same dispensing chamber 9 on the additive dispensing module 100 can be dispensed and used simultaneously or separately through the water outlets 11 on different additive dispensing modules 100 (not shown in the figures).

[0063] Preferably, in this embodiment, the main dispensing module 101 and the auxiliary dispensing module 102 in the additive dispensing device are connected by an interactive water passage 103; the first water box 21 of the main dispensing module 101 and the second water box 22 of the auxiliary dispensing module 102 are respectively provided with water outlets 11.

[0064] In this embodiment, the inlet of the water channel 4 on the auxiliary dispensing module 102 is connected to the dispensing chamber 9, and the outlet is connected via the interactive water channel 103, which can be switched by the control device, to the outlet 11 on the first water box 21 of the main dispensing module 101, and / or directly to the outlet 11 on the second water box 22 of the auxiliary dispensing module 102. This is for the purpose of dispensing the additive in the dispensing chamber 9 on the auxiliary dispensing module 102 directly to the outlet 11 on the second water box 22 of the auxiliary dispensing module 102, or to the outlet 11 on the first water box 21 of the main dispensing module 101 (not shown in the drawings).

[0065] Example 3

[0066] like Figures 1 to 6 As shown in the figure, this embodiment introduces a garment processing device, which includes: a shell 200, the shell 200 including a frame, and a shell layer can be wrapped around the frame to form an internally hollow shell structure; a water tank 300 is installed inside the shell 200, the water tank 300 is used for the additives flowing out of the outlet 11 of the additive dispensing module 100 and / or the inlet water to flow in, thereby realizing the effect of washing, rinsing, and renewing the load in the water tank 300 by using additives and / or inlet water.

[0067] In this embodiment, the additive dispensing device described in Embodiment 1 or 2 is installed inside the outer casing 200 of the garment processing equipment. The additive dispensing device is located inside the outer casing 200 and outside the water tank 300. The inlets of each water path of the additive dispensing module 100 are connected to the water inlet structure of the garment processing equipment via control components such as water inlet valves, and the outlets of each water path are connected to the inlet of the water tank 300 of the garment processing equipment via pipelines, so as to achieve the effect of dispensing additives and / or water into the water tank 300.

[0068] Meanwhile, in this embodiment, the additive dispensing device is fixedly installed on the outer casing 200.

[0069] In this embodiment, the water tank 300 extends horizontally or nearly horizontally back and forth and is centrally installed inside the outer casing 200. An additive dispensing module 100 fixed to the outer casing 200 is installed on the upper left and right sides of the water tank 300, respectively. The additive dispensing modules 100 on the left and right sides are connected by an interactive water passage 103 formed by the pipes above the water tank 300.

[0070] In this embodiment, only the example of a main dispensing module 101 on the left and a secondary dispensing module 102 on the right, with the main dispensing modules 101 and secondary dispensing modules 102 on both sides connected by an interactive waterway 103 formed by the pipes above the water tank 300, is shown in the accompanying drawings. However, the present invention is not limited to the above structure, and other embodiments can also be implemented, such as setting multiple dispensing modules on the left and right sides of the water tank 300, or setting a dispensing module below the water tank 300 (not shown in the drawings).

[0071] Example 4

[0072] like Figures 2 to 6 As shown, this embodiment introduces an additive dispensing module 100, including an independent main body composed of a water box 1. The interior of the water box 1 is hollow, forming an installation cavity 10. A drawer 2 that can be pulled outward is installed inside the installation cavity 10. The drawer 2 is provided with at least one dispensing cavity 9 for storing additives. The outlet of the dispensing cavity 9 is connected to the dispensing water channel 4 integrated on the water box 1 via a docking structure 8. The water box 1 is also provided with a rinsing water channel 5. The rinsing outlet 14 of the rinsing water channel 5 is opened towards the installation cavity 10 for rinsing the additives dripping at the docking structure 8.

[0073] By incorporating a rinsing water path into the additive dispensing device, the interior of the water tank is rinsed. This allows for the flushing of additives that drip into the mounting cavity from the self-connecting structure during the process of pulling the drawer into the water tank, thus preventing the accumulation of dripping additives within the water tank's mounting cavity. In particular, when the water tank lacks an outlet and the additives and / or water dispensed via the dispensing water path do not pass through the water tank, the mounting cavity is prone to developing odors due to accumulated additives, affecting the user experience. In this application, by adding a rinsing water path to the water tank, the mounting cavity can be rinsed, thereby effectively removing accumulated additives from the water tank.

[0074] In this embodiment, the docking structure 8 is located on the rear side of the mounting cavity 10, and the flushing water channel 5 is integrated on the upper cover 3 that forms the top wall of the water box 1. The upper cover 3 includes an upper cover plate 31 and a lower cover plate 32 that are interlocked with each other. The gap between the two cover plates 31 and 32 forms a hollow space. The two cover plates 31 and 32 are provided with protruding ribs to divide the hollow space into different water channels. The water channels include at least the injection water channel 4, the flushing water channel 5, etc.

[0075] In this embodiment, the flushing outlet 14 of the flushing water path 5 is located at the top cover 3 of the water box 1 above the docking structure 8, so that the flushing water flowing out of the flushing water path 5 is sprayed from top to bottom into the mounting cavity 10, directly spraying and rinsing the docking structure 8 and its vicinity, thereby improving the effect of rinsing the additives dripping from the docking structure 8.

[0076] In this embodiment, the front of the mounting cavity 10 of the water box 1 is open, and the drawer 2 can be pulled outward from the open and installed in the mounting cavity 10. A docking structure 8 is provided on the rear side of the mounting cavity 10. The dispensing cavity 9 is provided on the drawer 2, and the outlet of the dispensing cavity 9 is located on the rear side of the drawer 2 and can be connected to the inlet of the docking structure 8. The docking structure 8 has at least one outlet, and each outlet is connected to the inlet end of the dispensing water channel 4 integrated on the upper cover 3 of the water box 1. At the same time, the dispensing water channel 4 is provided with or connected to a suction structure to achieve the effect of using the docking structure 8 to suction and dispense the additive in the dispensing cavity 9 into the dispensing water channel 4. In this embodiment, the suction structure can be any structure of the prior art, such as a suction pump, a venturi tube, etc.

[0077] In this embodiment, the flushing outlet 14 of the flushing water path 5 is opened at the junction of the inlet of the docking structure 8 and the outlet of the dispensing cavity 9 provided on the drawer 2.

[0078] In this embodiment, the flushing water path 5 is integrated on the upper cover 3 of the water box 1; the two ends of the flushing water path 5 are the inlet end and the outlet end connected to the outside, respectively, and the flushing outlet 14 is provided in the middle of the flushing water path 5; preferably, the middle of the flushing water path 5 is provided with a bend 19 that changes the flow direction, and the flushing outlet 14 is provided at the bend 19, so that the water flow velocity is slowed down by using the bend 19 that changes the flow direction, and the residence time at the flushing outlet 14 is extended, thereby increasing the water flow rate and water pressure sprayed from the flushing outlet 14, and achieving the technical progress of significantly improving the flushing effect of the flushing water flow on the installation cavity.

[0079] In this embodiment, the outlet end of the flushing water path 5 is also provided with an overflow outlet 20; the two ends of the flushing water path 5 are respectively provided with an inlet and an overflow outlet 20 connected to the outside, and the flushing outlet 14 is located on the bottom wall at the outlet of the bend 19 in the middle of the flushing water path 5.

[0080] In this embodiment, the overflow outlet 20 is set higher than the flushing outlet 14; preferably, the flushing outlet 14 is located on the bottom wall of the flushing water passage 5 and faces downward, communicating with the lower mounting cavity 10, and the overflow outlet 20 is located on the closed side wall of the water outlet end of the flushing water passage 5 and horizontally penetrates the opening of the closed side wall.

[0081] In this embodiment, the diameter of the overflow outlet 20 is smaller than the diameter of the flushing outlet 14 and smaller than the pipe diameter of the flushing water passage 5; preferably, the sum of the cross-sectional area of ​​the flushing outlet 14 and the cross-sectional area of ​​the overflow outlet 20 is less than or equal to the cross-sectional area of ​​the inlet of the flushing water passage 5, so as to ensure that the water pressure inside the flushing water passage is not too high and that the water flow at the flushing outlet has a certain pressure.

[0082] Example 5

[0083] like Figures 2 to 6 As shown, this embodiment introduces an additive dispensing module 100, including an independent main body composed of a water box 1. The interior of the water box 1 is hollow, forming an installation cavity 10. A drawer 2 that can be pulled outward is installed in the installation cavity 10. The drawer 2 is provided with at least one dispensing cavity 9 for storing additives. The outlet of the dispensing cavity 9 is connected to the dispensing water channel 4 integrated on the water box 1 via a docking structure 8. The water box 1 is provided with a drain connector 7. One end of the drain connector 7 is connected to the lowest point of the installation cavity 10 of the water box 1, and the other end is connected to the outside of the water box 1 via a water outlet channel 6 provided on the water box 1.

[0084] By installing a drain connector on the additive dispensing module, the installation cavity is connected to the water outlet integrated on the water box, thereby achieving the effect of draining dripping liquid and rinsing water from the installation cavity using the water outlet on the dispensing module. At the same time, through the above-mentioned arrangement, the installation cavity inside the water box of the additive dispensing module, which is not supplied with inlet water, can be drained directly using the drain connector, thus ensuring the smooth drainage of rinsing water from the installation cavity and effectively preventing the generation of odors inside the water box.

[0085] In this embodiment, the drain connector 7 extends vertically within the mounting cavity 10. The lower end of the drain connector 7 is connected to the lowest point of the bottom wall of the mounting cavity 10, and the upper end is connected to the water outlet channel 6 integrated on the upper cover 3 of the water box 1. In this embodiment, the top wall of the water box 1 is formed by the upper cover 3, the water outlet channel 6 is integrated on the upper cover 3, and the top of the drain connector 7 is connected to the upper cover 3; preferably, the drain connector 7 and the upper cover 3 of the water box 1 are integrally formed.

[0086] In this embodiment, the outer wall of the drain connector 7 is provided with multiple reinforcing ribs that are arranged axially at intervals, protrude radially, and extend axially. The upper end of each reinforcing rib is connected to the upper cover 3 that constitutes the top wall of the water box 1, so as to improve the installation strength of the drain connector 7.

[0087] In this embodiment, the water box 1 of the additive dispensing module 100 includes an upper cover 3, and a water outlet 6 is integrated on the upper cover 3. The drain connector 7 is a vertically extending sleeve structure located on the lower side of the upper cover 3. The hollow channel inside the sleeve structure connects the upper water outlet 6 and the lower mounting cavity 10. The lower end of the drain connector 7 is in near contact with the bottom wall of the mounting cavity 10, so that the lower opening of the drain connector 7 can utilize the gap to achieve the purpose of pumping water; at the same time, the gap height is minimized to reduce the amount of residual water remaining in the mounting cavity 10 of the water box 1.

[0088] Preferably, the water outlet channel 6 is provided with or connected to a suction structure, which is used to generate suction force in the water outlet channel 6 to draw water from the installation cavity 10 along the drain connector 7 and the water outlet channel 6. The suction structure can be any structure in the prior art that can provide suction power, such as a suction pump, a venturi tube, etc.

[0089] In this embodiment, the additive dispensing module 100 is the additive dispensing module 100 in the above embodiment four, possessing all its technical features, and also having the following differences: the drain connector 7 and the flushing outlet 14 of the flushing water path 5 of the additive dispensing module 100 are respectively located on the left and right sides of the docking structure 8; the bottom wall of the mounting cavity 10 is inclined downward from the flushing outlet 14 connecting side to the drain connector 7 connecting side, so as to ensure that the flushing water flowing into the mounting cavity 10 from the flushing water path can converge and flow towards the drain connector, thereby achieving the purpose of all flushing water flowing smoothly out through the drain connector. Preferably, the mounting cavity 10 is a chamber structure with no opening on the bottom wall; in order to ensure that the flushing water flow does not flow randomly in the mounting cavity 10 and cause excessive drainage residue, such as Figure 6 As shown, a recessed groove 15 can be provided in the mounting cavity 10 below the docking structure 8. The drain connector 7 extends into the groove 15 and is positioned with a gap between it and the bottom of the groove 15. The flushing outlet 14 is opened towards the groove 15 so that the flushing water flow is gathered in the groove 15 and discharged from the drain connector 7 connected to the groove 15, thereby reducing the residual water in the mounting cavity 10.

[0090] In this embodiment, the inlet end of the water outlet 6 is connected to the drain connector 7 and the flushing water channel 5 via a tee 13. Preferably, the upper end of the vertically extending drain connector 7 is connected to the first opening A of the tee 13 facing downwards. The inlet end of the flushing water channel 5 is connected to an external water source, and the outlet end is connected to the second opening B of the tee 13 horizontally. The middle of the flushing water channel 5 is provided with a flushing outlet 14 facing the docking structure 8. The inlet end of the water outlet 6 is connected to the third opening C of the tee 13 horizontally, and the outlet end is connected to the outside of the additive dispensing module. Preferably, the tee 13 and the drain connector 7 are integrally formed. More preferably, the integral part formed by the tee 13 and the drain connector 7 is fixedly installed on the upper cover 3 of the water box 1, or directly integrally formed with the upper cover 3.

[0091] like Figures 1 to 6 As shown, in this embodiment, the second opening B and the third opening C of the tee 13 are coaxially arranged. The diameter of the third opening C of the tee 13 is smaller than the diameter of the second opening B, and the diameter of the third opening C is smaller than the diameter of the flushing water passage 5, so as to reduce the water flow from the flushing water passage 5 directly to the outlet water passage 6 through the tee 13, increase the flushing water output at the flushing outlet 14, and thus ensure the flushing effect.

[0092] Furthermore, the third opening C, which connects the tee 13 to the outlet water passage 6, is set higher than the flushing outlet 14 to ensure that most of the water flow in the flushing water passage 5 can flow out through the flushing outlet 14, thereby improving the flushing effect on the installation cavity 10. At the same time, excess water flow with excessive flow in the flushing water passage 5 can flow directly from the tee to the outlet water passage, avoiding excessive water pressure in the flushing water passage, which could cause leakage or even pipe bursting.
