[0052] The embodiment of the present invention provides a detergent dispensing device, which can be applied to washing machines, dishwashers, fruit and vegetable cleaning machines and other washing equipment. It should be noted that the application scenario type of the embodiment of the present invention does not limit the detergent dispensing device of the embodiment of the present invention.

[0053] The embodiment of the present invention provides a detergent dispensing device 100, Figure 1 and Figure 2 As shown, the detergent dispensing device 100 includes a dispenser box 1, a detergent box 2 and a detection component 4. Figure 2 As shown, the dispenser box 1 has at least one receiving slot 10 for receiving a detergent container 3, and the detergent container 3 can contain liquids such as laundry detergent, softener, disinfectant, perfume, etc. The dispenser box 1 has a plurality of receiving slots 10, one of which is a first receiving slot 101, and another is a second receiving slot 102. Of course, in other embodiments, the receiving slots 10 can also be set to three, four, or more, and the number of receiving slots 10 can be set according to specific washing needs. Figure 2 In the illustrated embodiment, the first receiving tank 101 and the second receiving tank 102 are both used to receive the detergent container 3. The detergent container 3 can be produced as a separate component, and the liquid contained in the detergent container 3 can be produced and sold separately. In other embodiments, the first receiving tank 101 can be used to receive the detergent container 3, and the second receiving tank is used to receive the hand-drop box, which means that the user can directly introduce fluid such as laundry detergent into the hand-drop box, and the hand-drop box then guides the fluid into the detergent box to mix and dilute with water. The user manually puts the amount of detergent required for a single wash into the hand-drop box.

[0054] like Figure 2 As shown, the dispenser box 1 is arranged in the detergent box 2, the detergent box 2 has a draw-out space, and the dispenser box 1 can be drawably arranged in the draw-out space in the detergent box 2. Figure 2 , the distributor box 1 is in a state of being drawn out from the drawer space. When the washing device is in normal use, the distributor box 1 is pushed into the drawer space.

[0055] like Figure 1 As shown, a mixing tank 20 is provided at the bottom of the detergent box 2, and the mixing tank 20 is located below the pull-out space. A liquid passage 21 is provided at the rear end of the detergent box 2. It should be noted that the front-to-back direction in the embodiment of the present invention represents the front-to-back direction of the washing device in normal use. In normal use, the front end of the washing device faces the direction of the user, and the rear end of the washing device faces away from the user. The front-to-back direction of the detergent box 2 is consistent with the front-to-back direction of the washing device, that is, the front end of the detergent box 2 faces the front end of the washing device, and the rear end of the detergent box 2 faces the rear end of the washing device. Figure 1 As shown, the liquid passage 21 is located in the detergent box 2, and the liquid passage 21 is connected to the water mixing tank 20. Since the water mixing tank 20 is located at the bottom of the detergent box 2, for the convenience of configuration, the bottom of the liquid passage 21 is connected to the water mixing tank 20. Among them, in the normal use state of the washing device, the detergent container 3 is installed in the receiving tank 10, and the detergent container 3 is connected to the liquid passage 21, that is, the fluid in the detergent container 3 can flow into the liquid passage 21, and the fluid in the liquid passage 21 can flow along the liquid passage 21 to the bottom of the liquid passage 21 under the action of gravity, and flow into the water mixing tank 20. The water mixing tank 20 is provided with an opening connected to the outside of the detergent dispensing device 100, and the fluid can flow directly or indirectly from the opening to the washing chamber of the washing device.

[0056] like Figure 1As shown, the detection component 4 in the embodiment of the present invention is arranged in the liquid passage 21. It should be noted that the embodiment of the present invention does not limit the specific position of the detection component 4 in the liquid passage 21. The detection component 4 can be arranged at the top, middle or bottom of the detection channel, as long as the detection component 4 is located in the liquid passage 21. In addition, the embodiment of the present invention does not limit the specific type of the detection component 4. No matter how the detection component 4 is arranged, as long as the detection component 4 can detect whether there is fluid passing through the liquid passage 21. For example, the detection method of the detection component 4 in the embodiment of the present invention can be detected under set conditions, for example, the detection component 4 is activated during the process of the washing device controlling the detergent container 3 to put liquid into the liquid passage 21. In the case that the detergent container 3 contains liquid such as laundry detergent, softener, disinfectant, perfume, etc., the fluid in the detergent container 3 flows into the liquid passage 21, and the detection component 4 located in the liquid passage 21 can detect that there is fluid flowing through the liquid passage 21, so the detection component 4 can determine that the detergent container 3 contains liquid such as laundry detergent, softener, disinfectant, perfume, etc. When the detection component 4 detects that there is no fluid flowing through the liquid passage 21, the detection component 4 can determine that there is no liquid such as laundry detergent, softener, disinfectant, perfume, etc. in the detergent container 3, that is, the detergent container 3 is in an empty bottle state, and the detection component 4 can determine that the detergent container 3 needs to be replaced or supplemented with fluid. This is conducive to improving the user's understanding of the capacity of the detergent container in the washing device, and facilitating the user to replace the detergent container 3 or supplement the fluid in time, thereby improving the user's experience and the washing degree of the clothes of the washing device.

[0057] The embodiment of the present invention provides a detergent dispensing device, which includes a dispenser box, a detergent box and a detection assembly. The dispenser box has at least one receiving tank for accommodating a detergent container, a mixing tank is provided at the bottom of the detergent box, a liquid passage connecting the mixing tank is provided at the rear end of the detergent box, the detergent container is connected to the liquid passage, and the detection assembly is arranged in the liquid passage to detect whether detergent flows to the liquid passage. In the embodiment of the present invention, by arranging the detection device in the liquid passage, compared with the method of arranging the detection device in the detergent container, the detection device does not need to contact the fluid in the detergent container at all times, and the fluid contacts the detection device only when the fluid in the detergent container flows to the liquid passage, and the detection device can detect that there is still fluid in the detergent container; the fluid flowing through the detection device will flow along the liquid passage to the mixing tank connected to the bottom of the liquid passage under the action of gravity, so that the fluid will not stay on the detection device, which is helpful for the detection device to detect the fluid next time, thereby improving the detection sensitivity of the detection device, so as to solve the problem of poor induction of the detection device to the fluid in the detergent container in the detergent dispensing device.

[0058] It should be noted that the detection component in the embodiment of the present invention is arranged in the water flow channel instead of in the mixing tank. After the detergent or other fluid flows through the detection component and enters the mixing tank, the surface of the detection component is not in contact with the detergent or other fluid at all times. Therefore, there is no need to separately isolate the power supply of the detection component to prevent leakage and electric shock, and the integrity is relatively high.

[0059] In some embodiments, Figure 1 and Figure 2 As shown, the detergent box 2 includes a box body 22 and a connector 23. A draw-out space for accommodating the dispenser box is formed inside the box body 22, a liquid passage 21 is provided at the rear of the draw-out space, and a mixing tank 20 is formed at the bottom of the box body 22, that is, the mixing tank 20 is arranged at the lower end of the draw-out space, and the dispenser box 1 is arranged in the draw-out space, that is, the dispenser box 1 is located above the mixing tank 20. Figure 1 As shown, the box body 22 is provided with a plurality of end walls around it, wherein the end wall at the rear end of the box body 22 is the first end wall 221. The connecting member 23 is disposed in the box body 22, and the connecting member 23 is spaced apart from the first end wall 221, and a liquid passage 21 is formed between the connecting member 23 and the first end wall 221. Figure 1 As shown, the connecting member 23 divides the interior of the box body 22 into two parts, the front part is the pull-out space and the mixing tank 20, and the rear part is the liquid passage 21. The connecting member 23 extends in the up and down directions, and the lower end of the connecting member 23 does not fully extend to the bottom of the box body 22. That is to say, the lower end of the connecting member 23 is spaced from the bottom of the box body 22, so that the liquid passage 21 and the mixing tank 20 are connected through the gap between the lower end of the connecting member 23 and the box body 22.

[0060] The embodiment of the present invention forms a liquid passage through the connection member and the first end wall of the rear end of the box body, and the liquid passage does not need to be formed inside the box body during processing, but is formed by the connection member and the surface of the box body, which is conducive to reducing the processing difficulty of the detergent box, thereby reducing the processing cost of the detergent box. The connection member is spaced from the bottom of the box body to connect the liquid passage and the mixing tank, and the structure is simple. The fluid naturally flows from the bottom of the liquid passage to the mixing tank under the action of gravity, which is conducive to reducing the retention of the fluid in the liquid passage and improving the sensitivity of the detection device in the liquid passage to detect the fluid.

[0061] In some embodiments, Figure 3 and Figure 4As shown, the detection assembly 4 includes at least one group of probes and a controller. At least one group of probes means that the detection assembly 4 can be provided with one group of probes, or two or more groups of probes, wherein each group of probes includes two probes 40. The two probes 40 in the same group of probes are arranged in the liquid passage 21 at intervals, and each group of probes is connected to the first end wall 221. The embodiment of the present invention does not limit the connection form between the probes and the first end wall 221. For example, the probes 40 can be detachably connected to the first end wall 221 by means of threads, and the probes 40 can be permanently fixed to the first end wall 221 by means of welding or pressing. Regardless of the method used to connect the probes 40 and the first end wall 221, as long as the probes 40 can remain relatively still with the first end wall 221, the probes 40 can stably protrude in the liquid passage 21, that is, the probes 40 are protrudingly arranged between the first end wall 221 and the connector 23. The distance between the two probes 40 in the same probe group is greater than the first set value and less than the second set value, that is, the two probes 40 in the same probe group are arranged at an interval, but the distance between the two probes is not too large. For example, the distance between the two probes is greater than 0 mm and less than or equal to 20 mm. This allows the fluid flowing through the liquid channel to flow to the two probes as much as possible, while reducing the risk of the fluid flowing to only one probe but not to the other probe.

[0062] In the embodiment of the present invention, the controller is connected to each probe 40, and the two probes 40 in each group of probes form a loop with the controller, and different groups of probes form different loops, and each loop can be independent of each other. The embodiment of the present invention determines whether liquid is introduced from the detergent container into the liquid passage 21 by detecting the conductivity of each group of probes 40. Specifically, the two probes in each group of probes form a loop with the controller. When there is no fluid flowing through the liquid passage 21, the medium between the two probes in the same group of probes is air, so the resistance between the two probes is large and the conductivity is low; when the fluid in the detergent container flows into the liquid passage 21, the fluid flows through the two probes in the same group of probes, and the medium between the two probes changes from air to fluid, so that the resistance between the two probes becomes smaller and the conductivity increases. The controller determines whether there is fluid flowing in the liquid passage by detecting the change of the conductive signal between the same group of probes. For example, during the process of the washing equipment controlling the fluid in the detergent container to flow to the liquid passage, if the conductivity in the same group of probes detected by the controller increases, it can be determined that there is still fluid in the detergent container; if the controller detects that the conductivity in the same group of probes is not much different from the conductivity when the washing equipment does not control the fluid in the detergent container to flow to the liquid passage, it can be determined that there is no fluid in the detergent container, and the controller can send an empty bottle signal to the control panel to remind the user to replenish the fluid into the detergent container in time, or to replace the detergent container with a new one in time.

[0063] It should be noted that if Figure 2 As shown, when a plurality of receiving slots 10 are provided in the dispenser box 1 to accommodate a plurality of detergent containers 3, a plurality of groups of probes may be provided, the number of which is equal to the number of the detergent containers 3, and each group of probes may be used to individually detect the remaining amount of fluid in each detergent container.

[0064] The embodiment of the present invention sets the detection device as a probe and a controller, each group of probes includes two spaced probes, and the probes protrude between the connector and the first end wall. When the fluid flows from the detergent container to the liquid passage, the fluid can flow through the two probes, and the conductivity of the loop formed by the two probes and the controller will increase. When no liquid flows to the liquid passage, the conductivity of the loop formed by the two probes and the controller is low. Therefore, by judging the conductivity, it can be judged whether there is fluid left in each detergent container. The contact area between the probe and the fluid is small, which is conducive to reducing the fluid remaining on the probe surface and affecting the next detection, thereby helping to improve the sensitivity of the detection device.

[0065] In some embodiments, Figure 1 As shown, the detergent dispensing device 100 further includes a dispensing pump 5. The dispensing pump 5 is used to draw the fluid in the detergent container into the liquid passage 21, and the fluid then flows through the liquid passage 21 to the mixing tank 20 at the bottom of the box body 22. Figure 1 As shown, the first end wall 221 has two opposite sides in the front-to-back direction, wherein the front side of the first end wall 221 is the liquid passage 21, and the delivery pump 5 is arranged on the side of the first end wall 221 away from the connecting member 23, that is, the delivery pump 5 is arranged on the rear side of the first end wall 221. The delivery pump 5 can be assembled to the first end wall 221 by means of buckles or screws. In the embodiment of the present invention, by arranging the delivery pump 5 on the rear side of the first end wall 221, it is possible to achieve the absorption of the fluid in the detergent container and reduce the occupation of the space in the box body 22, thereby increasing the storage space of the fluid and reducing the interference with the conduction of the fluid.

[0066] The dosing pump 5 in the embodiment of the present invention has at least one suction channel, that is, only one suction channel can be set inside the dosing pump 5, or two or more suction channels can be set inside the dosing pump 5. In the case where multiple suction channels are set inside the dosing pump 5, the multiple suction channels are independent of each other and do not interfere with each other, and the number of suction channels is the same as the number of receiving slots set in the dispenser box 1, that is, the number of suction channels is the same as the number of detergent containers. Each suction channel is used to absorb fluid in a detergent container. Figure 1As shown, each suction channel has a liquid inlet 51 and a liquid outlet 52, and the liquid inlet 51 is connected to the detergent container. It should be noted that the liquid inlet 51 in the embodiment of the present invention can be directly connected to the detergent container or indirectly connected. Figure 1 In the illustrated embodiment, the liquid inlet 51 is connected to the connector 23, and the connector 23 is connected to the detergent container, that is, the liquid inlet 51 is indirectly connected to the detergent container through the connector 23. The liquid outlet 52 is connected to the liquid passage 21, and negative pressure is generated inside the dosing pump 5, so that a pressure difference is formed between the liquid inlet 51 of the dosing pump 5 and the inside of the detergent container. The pressure in the detergent container is greater than the pressure in the suction passage in the dosing pump 5, so that the fluid in the detergent container flows from the liquid inlet 51 to the suction passage in the dosing pump 5, and the dosing pump 5 then guides the fluid in the suction passage from the liquid outlet 52 to the liquid passage 21.

[0067] like Figure 4 As shown, at least one probe in each group of probes 40 is arranged near the liquid outlet 52. Each group of probes includes a first probe 401 and a second probe 402. The first probe 401 and the second probe 402 are arranged at intervals, and the first probe 401 is closer to the liquid outlet 52 than the second probe 402. It should be noted that, when multiple groups of probes are arranged, the number of probe groups corresponds to the number of liquid outlets, one liquid outlet corresponds to one group of probes, and the first probe 401 in the group of probes is closer to the liquid outlet than the second probe 402.

[0068] The embodiment of the present invention is helpful to speed up the flow of the fluid in the detergent container into the liquid passage by arranging a delivery pump in the detergent delivery device, thereby improving the efficiency of the detergent delivery device in delivering liquid to the washing device, and further improving the washing efficiency of the washing device. Among them, the first probe in the same group of probes is closer to the liquid outlet than the second probe, which is helpful for the first probe to directly contact the liquid discharged from the liquid outlet, so as to accurately detect whether there is liquid flowing out of the detergent container at the liquid outlet. It is helpful to improve the detection sensitivity and accuracy of the detection device.

[0069] In some embodiments, Figure 4 As shown, the two probes 40 in each group of probes 40 are arranged in an alternating manner. Figure 4In the illustrated embodiment, two groups of probes are provided, namely, a first group of probes 41 and a second group of probes 42. Each group of probes corresponds to detecting whether a fluid flows out of a liquid outlet 52, and each group of probes is provided with a first probe 401 and a second probe 402. It should be noted that the staggered representation in the embodiment of the present invention means that the first probe 401 and the second probe 402 in the same group of probes will not overlap in the up-down direction and in the left-right direction. In other words, the first probe 401 and the second probe 402 are spaced apart in the up-down direction and in the left-right direction. In other words, the connecting line of the cross-section midpoints of the first probe 401 and the second probe 402 is at a set angle with the vertical direction, which can be understood as the connecting line being inclined relative to the vertical direction. When the fluid in the detergent container flows out from the liquid outlet 52, the fluid first flows to the first probe 401 near the liquid outlet 52, and under the guidance of the first probe 401, the fluid flows downward toward both sides of the first probe 401. Therefore, the embodiment of the present invention staggers the second probe with the first probe, and compared with arranging the first probe and the second probe at intervals in the vertical direction, the second probe is more likely to contact the fluid under the influence of the first probe, thereby facilitating the detection sensitivity and accuracy of the detection component. In addition, the inclined first and second probes are more conducive to the downward flow of the fluid, reducing the risk of the fluid remaining between the two probes.

[0070] In some embodiments, Figure 4 As shown, the direction of the connecting wires of the two probes (refer to Figure 4 The direction indicated by the dotted line) and the vertical direction (refer to Figure 4 The connecting line of the two probes (in the direction indicated by the dotted line in the middle) forms a first angle θ. It should be noted that the connecting line of the two probes represents the connecting line of the center points of the cross sections of the two probes. In the case where the cross-sectional area of ​​the probes is small, when the angle between the connecting line of the two probes and the vertical direction is too large, it is difficult for the liquid outlet to flow through the first probe and the second probe. In the case where the angle between the connecting line of the two probes and the vertical direction is too small, the liquid flowing out of the liquid outlet is affected by the guidance of the first probe and is difficult to flow to the second probe. The first angle θ in the embodiment of the present invention is greater than or equal to 30 degrees and less than or equal to 60 degrees. By limiting the first angle θ within a certain range, it is beneficial to increase the probability that the fluid flowing out of the liquid outlet flows to both the first probe and the second probe, thereby improving the sensitivity and accuracy of the detection component.

[0071] In some embodiments, Figure 4 As shown, the first probe 401 in the same set of probes is closer to the liquid outlet 52 than the second probe 402. Figure 4In the embodiment shown, two groups of probes are provided, namely, a first group of probes 41 and a second group of probes 42. The dispenser box is provided with two detergent containers, and the dispensing pump is provided with two liquid outlets 52, namely, a first liquid outlet 521 and a second liquid outlet 522. The first group of probes 41 is used to detect the fluid flowing out of the first liquid outlet 521, and the second group of probes 42 is used to detect the fluid flowing out of the second liquid outlet 522. Correspondingly, the first probe 401 in the first group of probes 41 is closer to the first liquid outlet 521 than the second probe 402, and is arranged in the horizontal direction (refer to Figure 4 In the left-right direction (shown in the figure), the second probe 402 is closer to the center of the mixing tank 20 relative to the first probe 401, wherein the center of the mixing tank 20 represents the geometric center of the mixing tank 20, that is, the second probe 402 in the first group of probes 41 is closer to the inside of the mixing tank 20 relative to the first probe 401, and the first probe 401 is closer to the edge of the mixing tank 20 relative to the second probe 402. The first probe 401 in the second group of probes 42 is closer to the second liquid outlet 522 relative to the second probe 402. And the first probe 401 in the second group of probes 42 is closer to the edge of the mixing tank 20 relative to the second probe 402 in the left-right direction. It should be noted that the positional relationship between the first probe 401 and the second probe 402 in the left-right direction in the embodiment of the present invention is related to the positional relationship between each liquid outlet in the left-right direction, and the positional relationship between the first probe, the second probe and the center of the mixing tank can satisfy the requirement of guiding the fluid to flow toward the center of the mixing tank instead of guiding the fluid to flow toward the edge of the mixing tank. The embodiment of the present invention facilitates guiding the fluid to flow toward the center of the water mixing tank by placing the second probe in the same group of probes opposite to the first probe, thereby reducing the risk of fluid remaining in the liquid passage and facilitating improving the utilization rate of fluids such as detergents.

[0072] In some embodiments, Figure 4 As shown, the detergent dispensing device further includes a guide rib 6. The guide rib 6 protrudes from the first end wall 221, and the guide rib 6 is arranged in the liquid passage 21, wherein the guide rib 6 can be connected to the first end wall 221, and the guide rib can also be connected to the connecting member 23 (refer to Figure 1 The guide rib 6 in the embodiment of the present invention can be integrally injection molded with the first end wall 221 or the connector 23, or can be fixedly connected by a mounting component. In the embodiment of the present invention, the guide rib is provided, the guide rib protrudes in the liquid passage 21, and the guide rib 6 at least extends from the vicinity of the liquid outlet 52 to the vicinity of the probe, so as to guide the fluid to the two probes 40 as much as possible, thereby improving the detection sensitivity of the detection component in the liquid passage to the fluid discharged from the liquid outlet.

[0073] In some embodiments, Figure 4As shown, the guide rib 6 includes a first extension portion 61. The extension direction of the first extension portion 61 is parallel to the connection line ( Figure 4 The angle between the extension direction of the guide rib 6 and the connecting line of the first probe 401 and the second probe 402 is less than 10 degrees. It should be noted that the extension direction of the guide rib 6 represents the maximum dimension direction of the guide rib 6. In the embodiment of the present invention, the angle between the extension direction of the guide rib 6 and the connecting line of the first probe 401 and the second probe 402 is less than 10 degrees, which means that the extension direction of the guide rib 6 is roughly parallel to the inclination direction of the first probe 401 and the second probe 402, and in the embodiment of the present invention, the first extension portion 61 is in the horizontal direction ( Figure 4 The projection of the first probe 401 (in the left and right directions as shown) at least overlaps with the liquid outlet 52, the first probe 401 and the second probe 402. The first probe 401 is located directly below the liquid outlet 52, or the angle between the connecting line of the first probe 401 and the liquid outlet 52 and the vertical direction is less than 15 degrees. It can be understood that the first probe 401 is located at the lower right of the liquid outlet 52, or the first probe 401 is located at the lower left. The positional relationship between the first probe 401 and the liquid outlet 52 can be determined based on the positional relationship between the liquid outlet 52 and the center of the mixing tank. That is to say, by setting the positional relationship between the first probe and the liquid outlet, the liquid discharged from the liquid outlet can be introduced into the center of the mixing tank rather than the edge as much as possible, thereby reducing the adhesion of the wall of the mixing tank to the liquid. For example Figure 4 In the illustrated embodiment, the first probe 401 is located at the lower right of the liquid outlet 52. That is, when the fluid flows out of the liquid outlet 52, the fluid flows to the surface of the guide rib 6 under the action of gravity, and the fluid flows along the surface of the extension direction of the guide rib 6. Since the distance between the guide rib 6 and the first probe and the second probe is less than the set value, the fluid passes through the first probe 401 and the second probe 402 respectively during the flow of the fluid along the surface of the guide rib 6, thereby realizing the conduction of the first probe 401 and the second probe 402, thereby improving the conductivity of the loop formed by the group of probes and the controller, indicating that there is still detergent or other fluid left in the detergent container corresponding to the liquid outlet. In the embodiment of the present invention, by making the extension direction of the first extension part in the guide rib and the direction of the connecting line of the first probe and the second probe less than the set angle, the fluid can pass through the first probe and the second probe during the flow along the guide rib, thereby increasing the probability of the fluid passing through the first probe and the second probe, thereby improving the sensitivity and accuracy of the detection component in detecting the fluid.

[0074] In some embodiments, Figure 5As shown, a plurality of protruding third extensions 63 are provided on one side of the first end wall 221 close to the water mixing tank 20, and each third extension 63 is arranged around a liquid inlet 51 to form a liquid suction cavity 631, and the liquid suction cavity 631 communicates with the liquid inlet 51 and the detergent container 3. Among them, a thimble 632 can also be provided in each liquid suction cavity 631, and the thimble 632 can be inserted into the detergent container 3, and the thimble 632 is used to guide the detergent or softener in the detergent container 3 into the liquid suction cavity 631, and then flow into the suction channel of the delivery pump 5 through the liquid inlet 51, and the detergent flows from the liquid outlet 52 of the delivery pump 5 to the liquid passage 21. The embodiment of the present invention provides a third extension portion, and a liquid suction channel is formed inside the third extension portion, so that the liquid inlet of the dosing pump can be staggered with the ejector pin of the detergent container. When the distance between the two liquid outlets 52 and the two liquid inlets 51 is small, the distance between the two ejectors can be set larger, thereby improving the flexibility of ejector pin setting, and further improving the flexibility of washing and container installation, which is conducive to reducing the difficulty of assembling the detergent dosing device. It is conducive to reducing the difficulty of assembling the detergent dosing device.

[0075] Combination Figure 5 As shown, in the embodiment of the present invention, the first suction channel is provided with a first liquid inlet 511, and the second suction channel is provided with a second liquid inlet 512. The first liquid inlet 511 and the second liquid inlet 512 are respectively used to introduce detergent into the dosing pump.

[0076] In some embodiments, Figure 5 As shown, the guide rib 6 includes a first guide rib 601 and a second guide rib 602. The first guide rib 601 is used to guide the liquid derived from the first liquid outlet 521 to the first group of probes 41, and the second guide rib 602 is used to guide the liquid derived from the second liquid outlet 522 to the second group of probes 42; wherein, the third extension portion 63 surrounding the first liquid inlet 511 forms part of the second guide rib 602, that is, the third extension portion 63 surrounding the first liquid inlet 511 partially overlaps with the second guide rib 602. Of course, in addition to being composed of part of the third extension portion 63, the second guide rib 602 can also continue to extend, so that the second guide rib 602 can guide the liquid to pass through each probe in the second group of probes 42. The embodiment of the present invention facilitates simplifying the structure, reducing costs, and improving the conduction efficiency of the liquid passage by arranging the second guide rib and the third extension portion to overlap partially.

[0077] In some embodiments, Figure 5 As shown, the guide rib 6 also includes a second extension portion 62. The second extension portion 62 is connected to one end of the first extension portion 61 close to the liquid outlet 52, and the angle between the extension direction of the second extension portion 62 and the vertical direction is less than 10 degrees, wherein the extension direction of the second extension portion 62 represents the maximum dimension direction of the second extension portion 62, and the vertical direction represents Figure 5In the up-down direction in the embodiment of the present invention, the angle between the extension direction of the second extension part 62 and the vertical direction is less than 10 degrees, that is, the second extension part extends substantially in the vertical direction, one end of the second extension part is close to the liquid outlet, and the other end of the second extension part is connected to the first extension part 61. When the fluid is discharged from the liquid outlet, the fluid flows directly downward along the second extension part 62, and the fluid flows along the second extension part 62 to the first extension part 61, so that the fluid passes through the first probe 401 and the second probe 402 close to the first extension part 61. The embodiment of the present invention is conducive to guiding the fluid flowing out of the liquid outlet to the first extension part to flow through the two probes by providing the second extension part, reducing the risk of the fluid flowing in other directions after flowing out of the liquid outlet, guiding the fluid, and improving the accuracy of detection of the detection component.

[0078] In some embodiments, Figure 4 As shown, the delivery pump 5 has a first suction channel and a second suction channel which are independent of each other. Figure 2 As shown, the dispenser box 1 has a first accommodating groove 101 and a second accommodating groove 102, and a first docking port 231 and a second docking port 232 are provided on a side of the connecting member 23 away from the first end wall 221, the first docking port 231 is connected to the detergent container 3 in the first accommodating groove 101, the second docking port 232 is connected to the detergent container 3 in the second accommodating groove 102, and the first suction channel in the dosing pump 5 is connected to the first docking port 231, and the second suction channel is connected to the second docking port 232. The first suction channel is used to extract detergent from the detergent container 3 placed in the first receiving tank 101 and discharge it into the mixing tank 20; the second suction channel is used to extract detergent from the detergent container 3 placed in the second receiving tank 102 and discharge it into the mixing tank 20; the detection component 4 is provided with a first group of probes 41 and a second group of probes 42, the first probe 401 in the first group of probes 41 is close to the first liquid outlet 521 of the first suction channel, and the first probe 401 in the second group of probes 42 is close to the second liquid outlet 522 of the second suction channel.

[0079] In some embodiments, Figure 3 and Figure 4As shown, the connecting member 23 is connected to the box body 22 through a plurality of fixing members 24. Specifically, the fixing members are connected to the first end wall 221 of the box body 22 and the connecting member 23. The fixing member 24 protrudes from the surface of the connecting member 23 toward the side of the liquid passage 21. It should be noted that the fixing members in the embodiment of the present invention include but are not limited to screws, clamping members and other components, as long as they can achieve the fixation of the relative position of the connecting member and the box body, so that a certain interval can be maintained between the connecting member 23 and the first end wall 221 and the liquid passage 21 is formed. The fixing member 24 in the embodiment of the present invention can be set to multiple, at least one of the multiple fixing members 24 is set below the liquid outlet 52, and the lower side represents the up and down direction of the detergent dispensing device in normal use. And the fixing member 24 located below the liquid outlet 52 is located above the detection component 4.

[0080] In the embodiment of the present invention, the connecting member and the box body are connected by a fixing member, and the fixing member is arranged below the liquid outlet. The fixing member can not only fix the connecting member and the box body, but also guide the discharged fluid. Specifically, when the fluid flows out of the liquid outlet, the fluid flows downward due to gravity, and the fluid is blocked by the fixing member below the liquid outlet. The fluid flows downward around the position of the fixing member, thereby forming a guide for the fluid by the fixing member, thereby improving the dispersion of the fluid, which is beneficial to increasing the probability of the fluid flowing to the first probe and the second probe at the same time, thereby improving the detection sensitivity of the detection component.

[0081] In some embodiments, Figure 4 As shown, the distance between the fixing member 24 disposed below the liquid outlet 52 and the liquid outlet 52 is less than a set value, that is, the fixing member 24 is disposed close to the liquid outlet 52, which can improve the stability of the connection between the connecting member and the box body on the one hand, and on the other hand, the liquid discharged from the liquid outlet can also be directly and quickly guided by the fixing member, thereby improving the diversion effect of the fluid.

[0082] In some embodiments, Figure 4 As shown, the distance between the fixing member 24 and the liquid outlet 52 is less than 10 mm. The distance between the fixing member 24 and the liquid outlet 52 represents the distance from the center of the cross-sectional area of ​​the liquid outlet 52 to the center of the cross-sectional area of ​​the fixing member 24, or the distance between the fixing member 24 and the liquid outlet 52 can also be the minimum distance between the cross-sectional outer contour of the fixing member 24 and the cross-sectional outer contour of the liquid outlet 52. In the embodiment of the present invention, by making the distance between the fixing member and the liquid outlet less than 10 mm, the fluid discharged from the liquid outlet can be quickly guided by the fixing member, thereby improving the effect of fluid diversion in the liquid passage, and further improving the accuracy of detection of the detection component.

[0083] In some embodiments, Figure 4As shown, the angle between the center line of the fixing member 24 and the liquid outlet 52 and the vertical direction is less than or equal to 15 degrees. The center line represents the line connecting the cross-sectional center of the fixing member 24 and the cross-sectional center of the liquid outlet 52. Figure 4 The vertical direction indicates the direction of the paper. Figure 4 In the embodiment of the present invention, the angle between the center line of the fixing part and the liquid outlet and the vertical direction is less than 15 degrees, so that the fixing part is not completely located directly below the liquid outlet, but the fixing part can guide the liquid discharged from the liquid outlet, which is beneficial to guide the liquid discharged from the liquid outlet in the direction in which the fixing part is offset relative to the liquid outlet.

[0084] exist Figure 4 In the illustrated embodiment, the fixing member 24 includes a first fixing member 241 and a second fixing member 242. The first fixing member 241 is arranged below the first liquid outlet 521, and the second fixing member 242 is arranged below the second liquid outlet 522. The angle between the center line of the first liquid outlet 521 and the first fixing member 241 and the vertical direction is less than 15 degrees, which is conducive to guiding the liquid discharged from the first liquid outlet 521 in the direction in which the first fixing member 241 is inclined. The angle between the center line of the second liquid outlet 522 and the second fixing member 242 and the vertical direction is less than 15 degrees, which is conducive to guiding the fluid discharged from the second liquid outlet 522 in the direction in which the second fixing member 242 is inclined.

[0085] In some embodiments, Figure 4 As shown, the first liquid outlet 521 is far away from the center of the mixing tank 20 relative to the second liquid outlet 522, and the first fixing member 241 is close to the center of the mixing tank 20 relative to the first liquid outlet 521 in the left-right direction, wherein the center of the mixing tank 20 represents the geometric center of the mixing tank 20, that is, the first fixing member 241 is close to the inside of the mixing tank 20 relative to the first liquid outlet 521 in the left-right direction, and the second fixing member 242 is close to the inside of the mixing tank 20 relative to the second liquid outlet 522 in the left-right direction, so that the fluid discharged from the first liquid outlet 521 is more easily guided to flow toward the center of the mixing tank 20 under the action of the first fixing member 241, and the fluid discharged from the second liquid outlet 522 is more easily guided to flow toward the center of the mixing tank 20 under the action of the second fixing member 242. It should be noted that the positional relationship between the first fixing member 241 and the second fixing member 242 in the left-right direction in the embodiment of the present invention is related to the positional relationship between the first liquid outlet and the second liquid outlet in the left-right direction. The positional relationship between the first fixing member and the first liquid outlet can satisfy the requirement of guiding the fluid to flow toward the center of the mixing tank rather than toward the edge of the mixing tank. The fluid flowing toward the center of the mixing tank is also more likely to flow to the first probe and the second probe in the same group of probes at the same time, which reduces the risk of fluid remaining in the liquid passage and is also conducive to improving the utilization rate of fluids such as detergents.

[0086] like Figure 4 As shown, the projections of the first fixing member 241 and the first liquid outlet 521 in the left-right direction partially overlap, and the fluid discharged from the first liquid outlet 521 moves vertically downward under the action of gravity. The first fixing member 241 overlapping in the left-right direction can at least guide the fluid discharged from the first liquid outlet 521. The projections of the second fixing member 242 and the second liquid outlet 522 in the left-right direction partially overlap, and the fluid discharged from the second liquid outlet 522 moves vertically downward under the action of gravity. The second fixing member 242 overlapping in the left-right direction can at least guide the fluid discharged from the second liquid outlet 522.

[0087] In some embodiments, Figure 4 As shown, at least one flushing port 222 connected to the liquid passage 21 is provided on the top of the box body 22. The flushing port 222 is connected to the external water flow. After the liquid outlet 52 introduces the detergent and other fluids into the liquid passage 21, the flushing port 222 introduces clean water into the liquid passage 21. On the one hand, the clean water can flush the probe 40 located in the liquid passage 21 to wash away the detergent and other fluids on the surface of the probe 40, so as to facilitate the effective detection of the subsequent probe, thereby improving the detection sensitivity of the detection component; on the other hand, the water flow entering the liquid passage 21 will continue to flow into the mixing tank 20 under the action of gravity, and the clean water is mixed with the detergent and other fluids to dilute the detergent, thereby improving the cleaning effect on the clothes.

[0088] In some embodiments, Figure 4 As shown, the number of flushing ports 222 is the same as the number of groups of probes 40 . Figure 4 In the illustrated embodiment, two groups of probes 40 are provided, and the flushing port includes a first flushing port 2221 and a second flushing port 2222, wherein the first flushing port 2221 is used to flush the first group of probes 41, and the second flushing port 2222 is used to flush the second group of probes 42, wherein the projection of the guide rib 6 in the left-right direction at least overlaps with the flushing port 222, for example, the first flushing port 2221 at least overlaps with the projection of the guide rib 6 in the left-right direction close to the first group of probes 41, and the second flushing port 2222 at least overlaps with the projection of the guide rib 6 in the left-right direction close to the second group of probes 42. This facilitates the clean water derived from the flushing port to flush the probes close to the guide ribs, so as to clean the detergent and other fluids remaining on the probe surfaces.

[0089] In some embodiments, Figure 6As shown, the detergent delivery device further includes a water guide pipe 7. The water mixing tank 20 is used to mix clean water and fluids such as detergents to dilute and mix the fluids such as detergents and introduce them into the washing chamber of the washing device through the downpipe 25. The water guide pipe 7 has a water inlet channel 71 connected to the downpipe 25. The water inlet channel 71 is used to introduce clean water into the downpipe 25 and impact the fluid in the downpipe 25 to flush the fluid with detergent into the washing chamber. Figure 6 As shown, at least part of the cross-sectional area of ​​the water inlet channel 71 is along the first direction ( Figure 6 The first direction is the direction from one end of the water pipe 7 away from the water channel 25 to the other end of the water pipe 7. Figure 6 The first direction in the illustrated embodiment is the left-right direction, and the first direction is parallel to the horizontal direction of the detergent dispenser 100 in normal use. The cross section of the water inlet channel 71 is perpendicular to the first direction. When the cross section of the water inlet channel 71 is a centrally symmetrical structure, the variation trend of the cross section of the water inlet channel 71 in the first direction can be shown by Figure 6 The dimension L of the water inlet channel in the vertical direction in the cross section shown is represented by: Figure 6 As shown, the dimension L on the left side of the water inlet channel 71 is greater than the dimension L on the right side of the water inlet channel. According to the principle of fluid mechanics, the cross-sectional dimension of the water inlet channel 71 along the first direction becomes smaller, the water flow pressure flowing through the water inlet channel 71 decreases, and the water flow speed increases, so that the water flow pressure at the outlet of the water inlet channel 71 is less than the pressure of the water outlet 252 of the water outlet channel 25. Under the action of the pressure difference, the water at the water outlet 252 of the water outlet channel 25 flows toward the outlet of the water inlet channel 71, so that the fluid in the water mixing tank 20 is sucked into the water outlet channel 25, and along with the water introduced by the water inlet channel 71, it is led out from the first water outlet 251 to the outside of the detergent dispensing device 100, that is, introduced into the washing chamber of the washing equipment.

[0090] The embodiment of the present invention arranges a water guide pipe portion in the sewer channel, and the cross-sectional area of ​​the water inlet channel in the water guide pipe decreases along a first direction toward one end close to the sewer channel, so that the water pressure introduced from the water inlet channel to the sewer channel is relatively small, and a negative pressure is formed in the sewer channel, so that the fluid in the mixing tank is quickly sucked into the sewer channel, and the fluid in the mixing tank is quickly mixed and diluted with the water flow in the water inlet channel and is quickly discharged from the first water outlet of the sewer channel, thereby improving the speed at which the detergent dispensing device dispenses detergent into the washing equipment.

[0091] In some embodiments, Figure 6 As shown in FIG. 1 , the water inlet channel 71 includes a large diameter portion 711 and a small diameter portion 712. The large diameter portion 711 extends from a first end 7111 away from the water discharge channel 25 to a second end 7112 close to the water discharge channel 25. In other words, the water inlet channel 71 is Figure 6 The large diameter portion 711 is extended in the left and right directions, and the cross-sectional area of ​​the large diameter portion 711 gradually decreases from the first end 7111 to the second end 7112. It should be noted that the gradual decrease means that the cross-sectional area of ​​the large diameter portion 711 gradually decreases along the first direction according to the set change value, so that the large diameter portion changes in a regular trend. In the embodiment of the present invention, by gradually reducing the cross-sectional area of ​​the large diameter portion from left to right, the direction in which the water flows into the water inlet channel 71 is also from left to right, that is, the flow direction of the water flow is consistent with the direction in which the cross-sectional area of ​​the large diameter portion decreases, so that the flow velocity of the water flow in the water inlet channel gradually increases, the water pressure gradually decreases, and the parameters of the water flow show a continuous change trend, thereby reducing the vibration and noise generated to the detergent dispensing device and improving the comfort of using the detergent dispensing device.

[0092] In the embodiment of the present invention, the small diameter portion 712 is connected to the second end 7112 of the large diameter portion 711 and extends into the sewer channel 25, wherein the cross-sectional area of ​​the small diameter portion 712 is a first constant. In other words, the cross-sectional area of ​​the small diameter portion 712 does not change from left to right, and the degree of change in velocity and water pressure of the water flow through the small diameter portion is small. The small diameter portion 712 guides the water flow introduced by the large diameter portion 711 into the sewer channel 25, and forms a water flow with a lower water pressure in the sewer channel, thereby quickly sucking the fluid in the mixing tank 20 from the sewer port 252 into the sewer channel 25, so that the water flow is mixed with the detergent and other fluids and rushed from the first water outlet 251 to the outside of the detergent dispensing device 100.

[0093] In some embodiments, Figure 6 As shown, the water inlet channel 71 further includes a guide portion 713. The guide portion 713 is arranged along a first direction ( Figure 6 The guide portion 713 is connected to the first end 7111 of the large diameter portion 711 (the left end of the large diameter portion 711), and the cross-sectional area of ​​the guide portion 713 is a second constant value, which is greater than the first constant value. In other words, the cross-sectional area of ​​the guide portion 713 is greater than the cross-sectional area of ​​the small diameter portion 712, and the cross-sectional area of ​​the guide portion 713 is equal to the cross-sectional area of ​​the first end 7111 of the large diameter portion 711, and the cross-sectional area of ​​the small diameter portion 712 is equal to the cross-sectional area of ​​the second end 7112 of the large diameter portion 711.

[0094] The embodiment of the present invention helps to reduce the difficulty of assembling the water guide pipe and the outside by setting a guide part with a constant cross-sectional area at the first end of the large diameter part. Setting the guide part to a constant value helps to rectify the water entering the water inlet channel, reduce the impact of the water flow on the entire detergent dispensing device, and thus reduce the noise of the entire detergent dispensing device.

[0095] In some embodiments, Figure 6As shown in FIG. 1 , the portion of the water pipe 7 corresponding to the small diameter portion 712 extends into the water channel 25, and the portion of the water pipe 7 corresponding to the large diameter portion 711 is located outside the water channel 25. The length direction of the water pipe 7 is arranged along the first direction, that is, the water entering the water inlet channel is from Figure 6 The water flows from left to right, and the extension direction of the drainage channel 25 also extends in the first direction. By aligning the extension direction of the water inlet channel with the extension direction of the drainage channel, it is beneficial to improve the guiding effect of the water flow introduced by the water inlet channel into the drainage channel on the detergent and other fluids, so that it flows out of the drainage channel faster. The embodiment of the present invention is beneficial to reduce the difficulty of assembling the water pipe and the water pipe by arranging the large diameter part outside the drainage channel and the small diameter part inside the drainage channel, thereby reducing the difficulty of processing the entire detergent delivery device and reducing the production cost.

[0096] In some embodiments, Figure 6 As shown, the water channel 25 extends along the front-to-back direction of the detergent box 2, the first water outlet 251 of the water channel 25 is located at the front end of the water channel 25, the water outlet 252 connecting the water channel 25 with the mixing tank 20 is arranged near the rear end of the water channel 25, and the small diameter portion 712 is near the rear end of the water channel 25. It should be noted that the front-to-back direction in the embodiment of the present invention represents the front-to-back direction of the washing device in normal use. In normal use, the front end of the washing device faces the direction of the user, and the rear end of the washing device faces away from the direction of the user, wherein the front-to-back direction of the detergent box 2 is consistent with the front-to-back direction of the washing device, that is, the front end of the detergent box 2 faces the front end of the washing device, and the rear end of the detergent box 2 faces the rear end of the washing device. In the embodiment of the present invention, the first water outlet of the water channel is arranged at the front end, and the water inlet is arranged at a position near the rear end, which is conducive to reducing the difficulty of assembling the entire detergent dispensing device with other components in the washing device and improving the compactness of assembly with other components. It should be noted that the water outlet 252 of the water channel is arranged near the rear end of the water channel 25, which means that the water outlet 252 is not necessarily arranged at the farthest end relative to the first water outlet 251 in the first direction, but can be arranged within a range less than a set value from the farthest end, such as Figure 6 In the illustrated embodiment, the water outlet 252 is disposed at the upper end of the water channel 25, that is, the fluid in the water mixing tank 20 flows from top to bottom into the water channel 25, and the direction in which the fluid enters the water channel is substantially perpendicular to the direction of the water flow in the water inlet channel 71, which is more conducive to forming a negative pressure at the position where the water flow is led out of the water guide pipe. This is conducive to increasing the speed at which the fluid in the water channel is mixed into the water flow, thereby increasing the liquid delivery speed of the detergent delivery device.

[0097] In some embodiments, Figure 6 As shown, the small diameter portion 712 is in the front-to-back direction ( Figure 6The projection of the small-diameter portion 712 (shown on the left and right sides) overlaps with the water outlet 252. In the embodiment of the present invention, by aligning the projection of the small-diameter portion 712 with the water outlet 252, the water flow in the small-diameter portion 712 can continue to flow forward along the small-diameter portion, thereby reducing the impact and interference of the fluid flowing out of the water outlet 252 on the water flow derived from the small-diameter portion, which is conducive to increasing the speed at which the water flow continues to move after mixing with the fluid such as detergent, thereby increasing the speed at which the detergent dispensing device dispenses liquid.

[0098] The present invention also provides a washing device. Figure 7 As shown, the washing device comprises a detergent dispensing device 100 and a washing tub 200 according to any of the above embodiments. The washing tub 200 is connected to the detergent dispensing device 100. The detergent dispensing device 100 is used to introduce fluids such as detergent and softener into the washing tub 200 to improve the washing efficiency of the washing device.

[0099] In some embodiments, Figure 7 As shown, the washing device further includes a door seal 300 , a water inlet pipe 400 and a water outlet pipe 500 . Figure 7 The dashed arrows shown in the figure indicate the direction of the water flow introduced by the water inlet valve 700. Figure 6 and Figure 7 As shown, a washing chamber 210 is provided inside the washing tub 200, and the washing chamber 210 is used to accommodate items to be washed. When the washing device is set as a clothes processing device, the washing chamber 210 can be a cavity formed by an inner barrel in the clothes processing device, and the clothes to be processed are placed in the washing chamber 210. The door seal 300 is arranged around the front end of the washing tub 200, and the door seal 300 is used to seal the gap between the washing tub 200 and the door body of the washing device. The water inlet pipe 400 is connected to at least the water guide pipe 7. The water inlet pipe 400 is used to introduce water flow into the downward water channel 25. In the embodiment of the present invention, the water inlet pipe 400 is configured as a three-way pipe. One end of the water inlet pipe 400 is connected to the outlet of the water inlet valve 700 to introduce an external water source. The water inlet pipe divides the external water source into two parts. One end of the water inlet pipe 400 is connected to the flushing port 222 located at the top of the box body. When there are two flushing ports 222, the water inlet pipe 400 can be divided into two branches. The other end of the water inlet pipe 400 is connected to the water guide pipe 7 located at the bottom of the box body. The external water source flushes into the detergent dispensing device from the top and the bottom of the box body respectively. Flushing of the detergent and other fluids in the detergent box is achieved from two positions, the water flow is mixed and diluted with the detergent and is discharged from the first water outlet 251 of the water channel 25, the water outlet pipe 500 connects the first water outlet 251 and the door seal 300, and the water outlet pipe 500 introduces the mixed diluted liquid in the water channel 25 into the washing chamber 210 through the door seal. The mixed liquid can quickly contact the objects in the washing chamber and wash them directly, thereby improving the utilization rate of the laundry liquid, and improving the cleanliness and washing efficiency of the washing equipment.

[0100] In some embodiments, in combination Figure 6 and Figure 7 As shown, the detergent dispensing device includes a water retaining rib 800. The water retaining rib 800 is arranged in the mixing tank 20 along the vertical direction to separate the mixing tank 20 into a first sub-cavity 201 and a second sub-cavity 202 that are parallel in the front-back direction. The first sub-cavity 201 is connected to the upper end of the second sub-cavity 202. The first sub-cavity 201 is close to the liquid passage 21 relative to the second sub-cavity 202, and the water discharge channel 25 is connected to the first sub-cavity 201. The washing device also includes an outer barrel, the outer barrel is provided with a cavity inside, the washing barrel 200 is arranged in the cavity, and the washing barrel 200 is provided with a water hole connecting the washing cavity 210 and the cavity; wherein the second sub-cavity 202 is also provided with a second water outlet connecting the washing barrel 200 and the outer barrel. In some implementations, the detergent dispensing device is also provided with a water discharge pipe 600. The water discharge pipe 600 is connected to the second water outlet of the second sub-cavity 202. The liquid first flows into the first sub-chamber 201 from the liquid passage 21, and the liquid in the first sub-chamber 201 first flows out from the first water outlet of the down-water passage 25 to the door seal, so that the mixed liquid directly flows into the washing chamber 210 in the washing tub 200. When the amount of liquid in the first sub-chamber 201 reaches a certain volume, the liquid level of the liquid in the first sub-chamber 201 is higher than the height of the water retaining rib 800, so that the liquid in the first sub-chamber 201 can flow into the second sub-chamber 202. The liquid entering the second sub-chamber 202 can flow from the down-water pipe 600 to between the washing tub 200 and the outer tub, and then flow into the washing chamber 210 through the water holes on the washing tub. This improves the efficiency of liquid conduction in the mixing tank.
