Abstract
Description
Technical Field
[0001] This invention belongs to the field of washing equipment technology, and specifically relates to a water inlet box module for a washing equipment. Background Technology
[0002] Existing top-loading washing machines typically include a cabinet, an outer tub suspended inside the cabinet, and an inner tub inside the outer tub that is driven to rotate by an outer shaft. The shaft is connected to a pulsator at the bottom of the inner tub. The water inlet module is an important component of the top-loading washing machine. Detergent (laundry powder, detergent, or fabric softener, etc.) is added to the detergent dispenser within the water inlet module. When water enters, the water flows through the water inlet module, flushing the inner cavity of the detergent dispenser, quickly dissolving the detergent, and allowing the detergent to flow with the water through the gap between the water inlet module and the detergent dispenser into the inner tub.
[0003] Normally, detergent is poured directly into the detergent dispenser, and then the water inlet valve is opened to allow water to enter, diluting and agitating the detergent before it flows into the water tank. Adding detergent before each wash is cumbersome, hence the development of automatic detergent dispensing devices. These devices pre-store multiple doses of detergent in the dispenser. During the wash cycle, a pump delivers the stored detergent to the water inlet assembly, allowing it to enter the washing tub along with the clean water, thus achieving automatic detergent dispensing.
[0004] Existing detergent dispensing devices typically involve installing suction pumps in each dispensing water path. The pumps draw detergent into the corresponding water path, dispensing it into the washing machine drum along with the incoming water flow. However, this method results in the detergent entering the drum directly with the water flow, leading to incomplete dissolution and potentially exposing clothes to a high concentration of detergent solution.
[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention
[0006] To address the aforementioned problems in the prior art, this invention proposes a water inlet box module for a washing device. This module introduces the detergent mixture from the water supply channel into the first spray chamber, enabling the detergent mixture to be sprayed and mixed with the water flowing out of the second channel, which facilitates the full dissolution of the automatically dispensed detergent.
[0007] To achieve the above-mentioned objectives, the present invention employs the following technical solution: A water inlet box module for a washing device, comprising: Water box; A liquid storage box, located inside the water box and used to store detergent; The water dispensing channel enables automatic dispensing of detergent from the storage box.

[0012] In some embodiments of this application, a plurality of vertically penetrating first spray holes are provided on the bottom wall of the first spray chamber, and the baffle is a frame structure extending upward along the first spray holes.
[0013] In some embodiments of this application, the height of the baffle is lower than the height inside the first spray chamber.
[0014] In some embodiments of this application, the ratio of the height inside the first spray chamber to the height of the baffle is 2 to 3.
[0015] In some embodiments of this application, a plurality of square first spray holes are provided at the bottom of the first spray chamber, and a water nozzle extending downward along the first spray holes is provided.
[0016] In some embodiments of this application, the water nozzle has a constricted water nozzle near the peripheral wall of the first spray chamber, the constricted water nozzle has a first vertical extension edge near the peripheral wall of the first spray chamber and a first inclined extension edge away from the peripheral wall of the first spray chamber, the first inclined extension edge being inclined in a downward direction toward the direction closer to the first vertical extension edge.
[0017] In some embodiments of this application, the water nozzle has an elongated water nozzle located in the middle of the first spray chamber.

[0019] In some embodiments of this application, a second spray chamber is provided on the box cover and a third water channel for supplying water to the first spray chamber, and a second dispensing chamber is provided in the dispensing box below the second spray chamber.
[0020] In some embodiments of this application, a water inlet channel connected to the second water channel is also included. A diversion channel is provided on the cover. The water inlet channel supplies water to both the second water channel and the diversion channel. The outlet of the diversion channel is located in the water storage tank.
[0021] In some embodiments of this application, it further includes an inlet water passage connected to the second waterway, an inlet valve for controlling the simultaneous opening and closing of the inlet water passage and the delivery water passage, and a suction pump connected to the inlet water passage for supplying secondary water.
[0022] In some embodiments of this application, the pump chamber of the water pump has a secondary water inlet connected to an external secondary water source, and the secondary water inlet is openable and closable. When the washing machine uses secondary water intake, the water inlet valve is first opened, and the water flow in the water inlet path will flow through the pump chamber of the water suction pump, so that the pump chamber is filled with water; then the water inlet valve is closed and the water suction pump is opened, and the water suction pump draws secondary water into the pump chamber through the secondary water inlet, and then flows into the first spray chamber through the water inlet path and the second water channel.
[0023] In some embodiments of this application, the liquid storage box has a first liquid storage chamber and a second liquid storage chamber. The dispensing water path is provided with a first dispensing water path for extracting the first detergent stored in the first liquid storage chamber and a second dispensing water path for extracting the second detergent stored in the second liquid storage chamber. The first dispensing water path and the second dispensing water path are respectively provided with a negative pressure suction structure, and the negative pressure ports of the two negative pressure suction structures are connected. When the inlet water flows through either dispensing water path, a negative pressure is formed in the other dispensing water path to extract the corresponding detergent.
[0024] In some embodiments of this application, after the detergent is extracted, water is simultaneously introduced into the first and second water inlet channels. The water flows through the channels and mixes with the detergent, and the detergent mixture is flushed into the first water channel.

The water flowing through the first dispensing path generates negative pressure and draws the second detergent into the second dispensing path. Then, simultaneously open the first and second water inlet valves to allow water to enter the water inlet path, the first dispensing path, and the second dispensing path at the same time. Use the flowing water to flush the second detergent extracted from the second dispensing path into the first spray chamber.
[0027] Compared with the prior art, the advantages and positive effects of the present invention are as follows: By introducing the detergent mixture in the water channel into the first spray chamber, the detergent mixture can be sprayed and mixed with the water flowing out of the second water channel, which is beneficial to the full dissolution of the automatically dispensed detergent. By setting the first and second guide parts, it is beneficial to ensure that the two water streams flow along the peripheral wall of the first spray chamber, turn, and collide with each other, which is beneficial to increase the full mixing of the two water streams; during the flow of water in the first spray chamber, part of the two water streams is directly sprayed out, achieving full mixing of the water streams.

[0036] See Figures 1-10 This is an embodiment of a water inlet box module for a washing device proposed in this invention. The water inlet box module 100 includes a water box 10, a liquid storage box 20, and a dispensing box 30. The liquid storage box 20 and the dispensing box 30 are installed inside the water box 10. The liquid storage box 20 can be opened by pulling it outwards and closed by pushing it inwards. The liquid storage box 20 is used to store detergent and automatically dispense it. The water box 10 is also equipped with an automatic dispensing module for drawing detergent from the liquid storage box 20 into the water storage tank 11 of the water box 10. The water box 10 is also connected to a water inlet pipe, which introduces water into the water storage box 10. The drawn detergent mixes with the water flow to form a detergent mixture. The bottom of the water storage tank 11 has a water outlet, allowing the detergent mixture and the water flow to flow out of the water storage tank 11 and into the washing tub of the washing machine. The dispensing box 30 can be opened by pulling it outwards and closed by pushing it inwards. The dispensing box 30 is used for manually dispensing detergent.
[0037] See Figure 2As shown, a first spray chamber 120, a first water channel 121, and a second water channel 122 connected to and arranged side-by-side are provided inside the cover 12 of the water tank 10. A dispensing water path 13 is connected to the first water channel 121. During automatic detergent dispensing, water containing a detergent mixture flows out of the dispensing water path 13. The first water channel 121 has a first guide section 1211 that directs the water flowing into the first spray chamber 120 away from the second water channel 122; the second water channel 122 has a second guide section 1221 that directs the water flowing into the first spray chamber 120 away from the first water channel 121. The first water channel 121 and the second water channel 122 flow into the first spray chamber 120 from back to front. The left-right dimension of the first spray chamber 120 is greater than the sum of the left-right dimensions of the first water channel 121 and the second water channel 122. Therefore, the water is designed to flow away from each other after flowing into the first spray chamber 120. This facilitates the two water streams to approach each other along the perimeter of the first spray chamber 120 and quickly spread out into the first spray chamber 120, avoiding slow-flow dead zones in the first spray chamber 120. Furthermore, the relative water streams collide and impact each other at the end, which helps to increase the mixing of the two water streams. During the flow of water in the first spray chamber, part of the two water streams is directly sprayed out, achieving full mixing of the water streams.
[0038] In some embodiments of this application, see Figure 3 As shown, a baffle 1201 is provided in the first spray chamber 120 to block part of the water flowing into the first spray chamber 120 from the second water channel 122. By providing the baffle 1201, the water flowing into the first spray chamber 120 helps maintain a higher water pressure, which is beneficial to the spraying force; and it also helps guide the flow of water. The second water channel 122 has a second outlet connected to the first spray chamber 120, and the baffle 1201 is located near the middle of the second outlet. The second guide section 1221 is provided with an arc-shaped water channel plate to realize the reverse flow of water. After the water flowing into the first spray chamber 120 from the second water channel 122 is blocked by the baffle 1201, most of the water flows past the side of the baffle 1201 away from the second water channel 122, and a small part of the water flows past the side closer to the second water channel 122.
[0039] In some embodiments of this application, a plurality of vertically penetrating first spray holes 1202 are provided on the bottom wall of the first spray chamber 120, and the flow-blocking part 1201 is a frame-shaped structure extending upward along the first spray holes 1202. The height of the flow-blocking part 1201 is lower than the internal height of the first spray chamber 120. The flow-blocking part 1201 serves to block the flow and also reduces the amount of water flowing into the first spray holes 1202 enclosed by the flow-blocking part 1201. Water flowing from the second water channel 122 into the first spray chamber 120 that is lower than the flow-blocking part 1201 cannot reach the interior of the flow-blocking part 1201; only water that is higher than the flow-blocking part 1201 can reach the interior of the flow-blocking part 1201. Preferably, the ratio of the internal height of the first spray chamber 120 to the height of the flow-blocking part 1201 is 2 to 3.
[0040] In some embodiments of this application, see Figure 7 and Figure 9 As shown, a plurality of square first spray holes 1202 are formed at the bottom of the first spray chamber 120, and water nozzles 1203 extending downward along the first spray holes 1202. The water nozzles 1203 have an elongated water nozzle 12031 located in the middle of the first spray chamber 120, which helps to increase the impact on the dispensing box 30. The water nozzles 1203 have a constricted water nozzle 12032 near the peripheral wall of the first spray chamber 120. The constricted water nozzle 12032 has a structure that is larger at the top and smaller at the bottom, which helps to increase the water pressure inside the constricted water nozzle 12032. The constricting water nozzle 12032 has a first vertical extension 120321 near the peripheral wall of the first spray chamber 120 and a first inclined extension 120322 away from the peripheral wall of the first spray chamber 120. The first inclined extension 120322 and the first vertical extension 120321 are arranged opposite to each other, and the first inclined extension 120322 is inclined downward towards the first vertical extension 120321. The arrangement of the first inclined extension 120322 is conducive to the outward spraying and diffusion of water after spraying, so that the water jet from the constricting water nozzle 12032 can impact the wall of the dispensing box 30, forming an impact on the box wall and playing a role in self-cleaning the dispensing box 30.
[0041] In some embodiments of this application, a first dispensing chamber 31 is provided within the dispensing box 30, located below the first spray chamber 120. Water in the first spray chamber 120 is sprayed into the first dispensing chamber 31 through multiple first spray holes 1202. The dispensing chamber 31 has an open top and an opening at the bottom; a siphon column is provided at the bottom opening of the dispensing chamber 31 to allow the mixed detergent solution to flow out, thereby improving the uniformity of mixing between the detergent and the incoming water. Detergent can be added manually or automatically into the first dispensing chamber 31.
[0042] In some embodiments of this application, a downwardly extending water guide frame 1204 is provided on the bottom wall of the first spray chamber 120. The water guide frame 1204 surrounds the outside of the first spray hole 1202 and is used to guide the water flowing out of the first spray chamber 120 into the first dispensing chamber 31. That is, it avoids the water from being sprayed onto the outside of the first dispensing chamber 31, especially the water from reaching the dispensing chamber adjacent to the first dispensing chamber 31.
[0043] In some embodiments of this application, the water inlet box module 100 further includes a second spray chamber 124 disposed on the box cover 12 and a third water channel 123 for supplying water to the first spray chamber. A second dispensing chamber 32 is provided in the dispensing box 30 below the second spray chamber 124. The second dispensing chamber 32 is used for manually dispensing fabric softener; the first dispensing chamber 31 is used for manually dispensing laundry detergent.
[0044] In some embodiments of this application, a water inlet channel 14 connected to the second water channel 122 is also included. A diversion channel 125 is provided on the cover 12. The water inlet channel 14 supplies water to both the second water channel 122 and the diversion channel 125. The outlet of the diversion channel 125 is located inside the water storage tank 11. By setting the diversion channel 125, a portion of the water flowing out of the water inlet channel 14 flows directly into the water storage tank 11, ensuring water intake efficiency; it also facilitates rinsing the water storage tank 11 and makes the water flow distribution at the outlet of the water storage tank 11 as uniform as possible in the left and right directions.
[0045] In some embodiments of this application, the water inlet box assembly 100 further includes a water inlet valve 50 for controlling the simultaneous opening and closing of the water inlet channel 14 and the water dispensing channel 13, thereby ensuring that the first water channel 121 and the second water channel 122 are supplied with water simultaneously. A water inlet pump 70 for supplying secondary water is provided on the water inlet channel 14. In the daily lives of washing machine users, a lot of domestic wastewater may be generated, some of which can be reused for washing and rinsing, and is called secondary water. To enable the washing machine to utilize secondary water, users generally collect the secondary water into a water container and then pump it into the washing machine's water inlet pipe through a pipeline equipped with a water inlet pump, thus achieving the reuse of secondary water. The water inlet pump 70 can directly pump the secondary water into the washing machine's washing tub through the dispensing device 100, thereby achieving the effective utilization of secondary water.
[0046] In some embodiments of this application, the pump chamber of the suction pump 70 has an inlet 71 and an outlet 72 connected to the inlet water passage 14, and a secondary water inlet 73 connected to an external secondary water source. The secondary water inlet 73 is openable and closable. The secondary water inlet 73 is located at the top of the pump chamber 74 of the suction pump 7 and faces upward. The secondary water inlet 73 is connected to the secondary water source through a pipeline equipped with a check valve. The check valve is used to ensure that the water flow in the pipeline flows only towards the secondary water inlet 73. Preferably, in order to ensure the direction of water flow, a check valve is provided on the delivery water passage 13 upstream of the suction pump 7 to control that the secondary water flowing into the pump chamber 74 can only flow out from the outlet 72 of the suction pump 7 and prevent it from flowing back towards the inlet valve 5. The outlet 72 is connected to the inlet valve 50 via the connecting pipe on the inlet water passage 14, and the outlet 72 is connected to the second waterway 122 via the connecting pipe on the inlet water passage 14, so that the suction pump 7 is connected in series on the inlet water passage 14, so that the water flow in the inlet water passage 14 flows through the suction pump 7, realizing the filling of the suction pump 7 with water and filling the pump chamber of the suction pump 7, thereby ensuring that the suction pump 7 can directly draw water after water enters the inlet water passage 14, and pump the secondary water into the dispensing device for use.
[0047] In some embodiments of this application, the liquid storage box 20 has a first liquid storage chamber 21 and a second liquid storage chamber 22. The first liquid storage chamber 21 is used to store laundry detergent, and the second liquid storage chamber 22 is used to store fabric softener. The dispensing water path 13 includes a first dispensing water path 131 and a second dispensing water path 132. The first dispensing water path 131 is used to draw the first detergent stored in the first liquid storage chamber 21; the second dispensing water path 132 is used to draw the second detergent stored in the second liquid storage chamber 22. The inlet ends of the first dispensing water path 131 and the second dispensing water path 132 are connected to an inlet valve 50, which is used to controllably introduce water flow into the first dispensing water path 131 and the second dispensing water path 132, either separately or simultaneously. The first water delivery channel 131 is equipped with a first negative pressure suction structure 41, and the second water delivery channel 132 is equipped with a second negative pressure suction structure 42. The negative pressure suction structure 40 can generate negative pressure at the negative pressure port by utilizing the water flow through the water delivery channel. The negative pressure ports of the first negative pressure suction structure 41 and the second negative pressure suction structure 42 are connected, and the first water delivery channel 131 is connected to the first liquid storage chamber 211, and the second water delivery channel 132 is connected to the second liquid storage chamber 212. The negative pressure of the negative pressure suction structure 40 can act on the other water delivery channel to extract the detergent stored in the liquid storage chamber connected to that water delivery channel. Then, water is simultaneously introduced into both water delivery channels, and the incoming water flows through the first water delivery channel 131 and the second water delivery channel 132 at the same time, so that the detergent extracted in the previous step can be mixed with the re-entering water flow to form a detergent mixture.
[0048] In some embodiments of this application, in order to improve the efficiency of detergent dispensing after extraction by utilizing two switchable dispensing water channels 13 for corresponding detergent extraction, the following settings can be made: The first negative pressure port 411 of the first negative pressure suction structure 41 and the second negative pressure port 421 of the second negative pressure suction structure 42 are directly connected through a pipeline; the inlet end of the first water delivery channel 131 and the inlet end of the second water delivery channel 132 are respectively connected to the water delivery pipe through the corresponding water delivery valve 50; the outlet end of the first water delivery channel 131 and the outlet end of the second water delivery channel 132 are both connected to the first water channel 121, so that the detergent mixture is delivered into the washing tub after passing through the first spray chamber 120, the first delivery chamber 31 and the water storage tank 11. The first negative pressure suction structure 41 is connected in series at the inlet end of the first water delivery channel 131, and the second negative pressure suction structure 42 is connected in series at the inlet end of the second water delivery channel 132. The first water delivery channel 131 is connected to the first liquid storage chamber 211 at the outlet end, and the first liquid storage chamber 211 stores the first detergent. The second water delivery channel 132 is connected to the second liquid storage chamber 212 at the outlet end, and the second liquid storage chamber 212 stores the second detergent.
[0049] In some embodiments of this application, the water inlet valve 50 includes a first water inlet valve 51, a second water inlet valve 52, and a third water inlet valve 53. The inlet end of the first water supply channel 131 is connected to the first water inlet valve 51, the inlet end of the second water supply channel 132 is connected to the second water inlet valve 52, the inlet end of the third water channel 123 is connected to the third water inlet valve 53, and the inlet end of the water inlet channel 14 is connected to both the first water inlet valve 51 and the second water inlet valve 52. When the first water inlet valve 51 is open, water in the inlet pipe is supplied to the first water supply channel 131 and the water inlet channel 14; the first water inlet valve 51 controls the opening and closing of the first water supply channel 131 and the water inlet channel 14. When the second water inlet valve 51 is open, water in the inlet pipe is supplied to the second water supply channel 132 and the water inlet channel 14; the second water inlet valve 51 controls the opening and closing of the second water supply channel 132 and the water inlet channel 14.
