In other embodiments, the first receiving tank 101 can be used to receive the detergent container 3, and the second receiving tank can be used to receive a hand drop box, where the hand drop box indicates that a user can directly introduce a fluid such as laundry detergent into the hand drop box, and the hand drop box then guides the fluid into the detergent box to be mixed and diluted with water. The user manually puts the dosage of the detergent required by single washing into the hand throwing box.

As shown in fig. 2, the dispenser box 1 is disposed in the detergent box 2, the detergent box 2 has a drawing space, and the dispenser box 1 is drawably disposed in the drawing space in the detergent box 2. Referring to fig. 2, the dispenser box 1 is in a state of being drawn out from the drawing space. During normal use of the washing appliance, the dispenser box 1 is pushed into the pull-out space.

As shown in fig. 1, a water mixing tank 20 is disposed at the bottom of the detergent box 2, the water mixing tank 20 is located below the drawing space, and a liquid passing channel 21 is disposed at the rear end of the detergent box 2. It should be noted that, in the embodiment of the present invention, the front-back direction indicates the front-back direction of the washing device in the normal use state, the front end of the washing device faces the user, and the rear end of the washing device faces away from the user, where the front-back direction of the detergent box 2 is the same as the front-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. As shown in fig. 1, the liquid passing channel 21 is located in the detergent box 2, and the liquid passing channel 21 communicates with the water mixing tank 20.

In addition, the embodiment of the present invention does not limit the specific type of the detection assembly 4, and no matter what the arrangement manner of the detection assembly 4 is, the detection assembly 4 can detect whether the fluid passes through the fluid passage 21. For example, the detection mode of the detection assembly 4 in the embodiment of the present invention may detect under a set condition, for example, the detection assembly 4 is activated during the washing device controls the detergent container 3 to dispense the liquid into the liquid passage 21. Under the condition that the detergent container 3 contains the liquid such as the laundry detergent, the softener, the disinfectant and the perfume, the liquid in the detergent container 3 flows into the liquid passing channel 21, and the detection assembly 4 positioned in the liquid passing channel 21 can detect that the liquid passes through the liquid passing channel 21, so that the detection assembly 4 can judge that the detergent container 3 contains the liquid such as the laundry detergent, the softener, the disinfectant and the perfume. In case the detection assembly 4 detects that there is no fluid flowing through the liquid passing channel 21, the detection assembly 4 can determine that the detergent container 3 has no fluid such as laundry detergent, softener, disinfectant, perfume, etc., i.e. the detergent container 3 is in an empty bottle state, and the detection assembly 4 can determine that the detergent container 3 needs to be replaced or needs to be replenished with fluid. The method is beneficial to improving the understanding degree of the user on the capacity of the detergent container in the washing equipment, and is convenient for the user to replace the detergent container 3 or supplement fluid in time, thereby improving the experience of the user and the cleanliness of clothes of the washing equipment.

It should be noted that, the detection assembly in the embodiment of the present invention is disposed in the water passage, rather than the water mixing tank, and after the fluid such as the detergent flows through the detection assembly and enters the water mixing tank, the surface of the detection assembly does not constantly contact with the fluid such as the detergent, so that a separate power supply for isolating the detection assembly is not required to prevent electric leakage and electric shock, and the completeness is high.

In some embodiments, as shown in fig. 1 and 2, the detergent box 2 includes a box body 22, a connector 23. The box body 22 forms a drawing space for accommodating the dispenser box, the rear part of the drawing space is provided with the liquid passing channel 21, the bottom of the box body 22 forms the water mixing tank 20, that is, the water mixing tank 20 is arranged at the lower end of the drawing space, and the dispenser box 1 is arranged in the drawing space, that is, the dispenser box 1 is positioned above the water mixing tank 20. As shown in fig. 1, a plurality of end walls are disposed around the box 22, wherein the end wall at the rear end of the box 22 is a first end wall 221. The connecting member 23 is disposed in the box 22, and the connecting member 23 is spaced from the first end wall 221, and the liquid passing channel 21 is formed between the connecting member 23 and the first end wall 221. As shown in fig. 1, the connecting member 23 divides the interior of the case 22 into a front portion and a rear portion, the front portion is a drawing space and the water mixing tank 20, the rear portion is a liquid passing channel 21, the connecting member 23 extends in the up-down direction, and the lower end of the connecting member 23 does not extend completely to the bottom of the case 22, that is, the lower end of the connecting member 23 is spaced from the bottom of the case 22, so that the liquid passing channel 21 is communicated with the water mixing tank 20 through a gap between the lower end of the connecting member 23 and the case 22.

According to the embodiment of the invention, the detergent box is arranged into the box body and the connecting piece arranged in the box body, the connecting piece and the first end wall at the rear end of the box body form the liquid passing channel at intervals, the liquid passing channel is not required to be formed in the box body in the processing process, but the liquid passing channel is formed at intervals on the surface of the box body through the connecting piece, so that the processing difficulty of the detergent box is favorably reduced, and the processing cost of the detergent box is reduced. And the connecting piece is spaced from the bottom of the box body to pass through the liquid channel and the water mixing groove, so that the structure is simple, fluid naturally flows from the bottom of the liquid passing channel to the water mixing groove under the action of gravity, the stay of the fluid in the liquid passing channel is favorably reduced, and the sensitivity of the detection device in the liquid passing channel for detecting the fluid is favorably improved.

In some embodiments, as shown in fig. 3 and 4, the probing assembly 4 includes at least one set of probes and a controller. At least one group of probes indicates that the probing assembly 4 may be provided with one group of probes, or may be provided with two or more groups of probes, wherein each group of probes includes two probes 40. Two probes 40 in the same group of probes are arranged in the liquid passing channel 21 at intervals, and each group of probes is connected with the first end wall 221, but the embodiment of the invention does not limit the connection form of the probes and the first end wall 221, for example, the probes 40 can be detachably connected with the first end wall 221 by means of threads, and the probes 40 can be permanently fixed with the first end wall 221 by means of welding or pressing. Whatever the way the probe 40 is connected to the first end wall 221, the probe 40 can be kept stationary relative to the first end wall 221, so that the probe 40 can stably protrude in the liquid passing channel 21, that is, the probe 40 is protrudingly disposed between the first end wall 221 and the connecting piece 23. The distance between two probes 40 in the same group of probes is greater than the first set value and less than the second set value, that is, the two probes 40 in the same group of probes are spaced apart from each other, but the distance between the two probes is not too large. For example, the distance between the two probes is greater than 0mm and 20mm or less. Fluid flowing through the fluid channel can flow as far as possible to both probes, reducing the risk of fluid flowing only to one probe and not to the other.

In the embodiment of the present invention, the controller is connected to each probe 40, two probes 40 in each group of probes form a loop with the controller, different loops are formed between different groups of probes, and the loops can be independent of each other. The embodiment of the present invention determines whether or not liquid is introduced into the liquid passing passage 21 from the detergent container by detecting the conductivity of each set of the probes 40. Specifically, two probes in each group of probes form a loop with the controller, and under the condition that no fluid flows through the liquid passing channel 21, the medium between the two probes in the same group of probes is air, so that the resistance between the two probes is large, and the conductivity is low; in the case that the fluid in the detergent container flows into the through-liquid channel 21, the fluid flows through two probes in the same group of probes, the medium between the two probes is changed from air to fluid, so that the resistance between the two probes is reduced, the conductivity is increased, and the controller judges whether the fluid flows through the through-liquid channel by detecting the change of the conductive signal between the probes in the same group. For example, in the process of controlling the fluid in the detergent container to flow to the liquid passing channel by the washing equipment, if the controller detects that the conductivity in the probes in the same group is increased, the detergent container can be judged to have the fluid; if the controller detects that the conductivity of the probes in the same group does not change greatly from the conductivity when the washing equipment does not control the fluid in the detergent container to flow to the liquid passage, the controller can judge that no fluid exists in the detergent container, and can send out an empty bottle signal to the control panel to remind a user of timely replenishing the fluid to the detergent container or timely replacing a new detergent container.

Note that, as shown in fig. 2, in the case where a plurality of housing grooves 10 are provided in the dispenser box 1 to house a plurality of detergent containers 3, a plurality of sets of probes, the number of which is equal to the number of detergent containers 3, may be provided, and the remaining amount of fluid in each detergent container can be individually detected by each set of probes.

In the embodiment of the invention, the detection device is arranged into the probes and the controller, each group of probes comprises two spaced probes, the probes protrude between the connecting piece and the first end wall, fluid can flow through the two probes under the condition that the fluid flows from the detergent container to the liquid passing channel, the electric conductivity of a loop formed by the two probes and the controller is increased, and the electric conductivity of the loop formed by the two probes and the controller is lower under the condition that no fluid flows to the liquid passing channel, so that whether the fluid remains in each detergent container can be judged by judging the electric conductivity. The contact area between the probe and the fluid is small, so that the influence of the fluid remaining on the surface of the probe on the next detection is reduced, and the sensitivity of the detection device is improved.

In some embodiments, as shown in fig. 1, the detergent dispensing device 100 further comprises a dispensing pump 5. The dosing pump 5 is used for pumping the fluid in the detergent container into the liquid passing channel 21, and the fluid flows into the water mixing tank 20 at the bottom of the box body 22 through the liquid passing channel 21. As shown in fig. 1, the first end wall 221 has two opposite sides in the front-rear direction, wherein the front side of the first end wall 221 is the liquid passing channel 21, and the dosing pump 5 is disposed on the side of the first end wall 221 away from the connecting member 23, that is, the dosing pump 5 is disposed on the rear side of the first end wall 221. The dosing pump 5 may be fitted to the first end wall 221 by means of a snap or screw. In the embodiment of the present invention, the dosing pump 5 is disposed at the rear side of the first end wall 221, so that the fluid in the detergent container can be sucked, and the space occupied in the box body 22 can be reduced, thereby increasing the fluid storage space and reducing the interference on the fluid conduction.

The dosing pump 5 in the embodiment of the present invention has at least one suction channel, that is, only one suction channel may be disposed inside the dosing pump 5, and two or more suction channels may be disposed inside the dosing pump 5, in case that a plurality of suction channels are disposed inside the dosing pump 5, the plurality of suction channels are independent from each other and do not interfere with each other, and the number of suction channels is the same as the number of receiving grooves disposed in the dispenser cartridge 1, that is, the number of suction channels is the same as the number of detergent containers disposed therein. Each suction channel is used for sucking up the fluid in one detergent container. As shown in fig. 1, each suction channel has a liquid inlet 51 and a liquid outlet 52, the liquid inlet 51 is communicated with the detergent container, it should be noted that, in the embodiment of the present invention, the liquid inlet 51 is directly or indirectly communicated with the detergent container, in the embodiment shown in fig. 1, the liquid inlet 51 is communicated with the connecting member 23, and the connecting member 23 is further communicated with the detergent container, that is, the liquid inlet 51 is indirectly communicated with the detergent container through the connecting member 23. The liquid outlet 52 is connected to the liquid passage 21, a 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 inside the detergent container is greater than the pressure of 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 fluid in the suction passage is guided from the liquid outlet 52 to the liquid passing passage 21 by the dosing pump 5.

As shown in fig. 4, at least one probe of each set of probes 40 is disposed proximate to the exit orifice 52. Wherein each set of probes comprises a first probe 401 and a second probe 402. First probe 401 and second probe 402 set up at the interval, and first probe 401 is close to liquid outlet 52 relative to second probe 402, and it should be noted that, under the condition that sets up multiunit probe, the group number of probe corresponds with the quantity of liquid outlet, and a liquid outlet corresponds a set of probe, and first probe 401 in this set of probe is close to this liquid outlet relative to second probe 402.

According to the embodiment of the invention, the putting pump is arranged in the detergent putting device, so that the speed of the fluid in the detergent container flowing into the liquid passing channel is increased, the efficiency of putting the liquid into the washing equipment by the detergent putting device is improved, and the washing efficiency of the washing equipment is improved. Wherein, first probe in the same group of probe is close to the liquid outlet relatively the second probe, is favorable to first probe can direct contact to the liquid that the liquid outlet was derived to whether the liquid outlet has the liquid outflow from the detergent container that detects that can be accurate. The detection sensitivity and accuracy of the detection device are improved.

For example, in the embodiment shown in fig. 4, two sets of probes, namely a first set of probes 41 and a second set of probes 42, are provided, each set of probes is used for detecting whether a fluid flows out of one fluid outlet 52, and each set 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 do not overlap in both the vertical direction and the left-right direction. That is, the first probe 401 and the second probe 402 are spaced in both the up-down direction and the left-right direction. That is, a connecting line between the cross-sectional midpoints of the first probe 401 and the second probe 402 forms a set angle with the vertical direction, and it can be understood that the connecting line is disposed obliquely with respect to the vertical direction. In the case that the fluid in the detergent container flows out from the liquid outlet 52, the fluid flows to the first probe 401 near the liquid outlet 52, and the fluid flows downwards towards both sides of the first probe 401 under the guidance of the first probe 401, so that, by arranging the second probe and the first probe in a staggered manner, the second probe is more easily contacted with the fluid under the influence of the first probe than by arranging the first probe and the second probe at intervals in the vertical direction, thereby being beneficial to improving the sensitivity and accuracy of detection of the detection assembly. And the inclined first probe and the inclined second probe are more favorable for the fluid to flow downwards, and the risk of the fluid remaining between the two probes is reduced.

In some embodiments, as shown in fig. 4, the direction of the connecting line of the two probes (see the direction indicated by the dashed line in fig. 4) forms a first angle θ with the vertical direction (see the direction indicated by the dashed line in fig. 4). The connecting line between the two probes indicates a connecting line between the center points of the cross sections of the two probes. Under the less condition of the sectional area of probe, under the too big condition of contained angle of the connecting wire direction of two probes and vertical direction, the degree of difficulty that first probe and second probe were flowed to the liquid outlet is great, under the too little condition of the orientation of the connecting wire of two probes and vertical direction's contained angle, the liquid that the liquid outlet flows out is influenced and difficult the flowing to the second probe by the water conservancy diversion of first probe. The first included angle theta in the embodiment of the invention is greater than or equal to 30 degrees and less than or equal to 60 degrees, and the first included angle theta is limited in a certain range, so that the probability that the fluid flowing out of the liquid outlet flows to the first probe and the second probe is favorably improved, and the sensitivity and the accuracy of the detection assembly are improved.

In some embodiments, as shown in fig. 6, the detergent dispensing device further includes a water conduit 7. The water mixing tank 20 is used for mixing clean water and fluid such as detergent, so as to dilute and mix the fluid such as detergent, and introduce the fluid into a washing cavity of the washing device through the water drainage channel 25. Wherein, the water guiding pipe 7 has a water inlet channel 71 communicated with the water outlet channel 25 inside, and the water inlet channel 71 is used for guiding clean water to the water outlet channel 25 and impacting the fluid in the water outlet channel 25 to flush the fluid with detergent into the washing cavity. As shown in fig. 6, at least a part of the cross-sectional area of the water inlet channel 71 decreases along a first direction (a left-right direction shown in fig. 6) in which one end of the water conduit 7 away from the water outlet channel 25 faces the other end of the water conduit 7, and the first direction in the embodiment shown in fig. 6 is a left-right direction and is parallel to a horizontal direction of the detergent dispenser 100 in a normal use state. The cross section of the inlet channel 71 is perpendicular to the first direction, and in the case that the cross section of the inlet channel 71 has a central symmetrical structure, the trend of the change of the cross section of the inlet channel 71 in the first direction can be represented by the dimension L of the inlet channel in the up-down direction in the cross section shown in fig. 6, and as shown in fig. 6, the dimension L on the left side of the inlet channel 71 is larger than the dimension L on the right side of the inlet channel. According to the principle of fluid mechanics, the cross-sectional dimension of the water inlet channel 71 along the first direction is reduced, the pressure of the water flowing through the water inlet channel 71 is reduced, the water flow speed is increased, so that the pressure of the water at the outlet of the water inlet channel 71 is smaller than the pressure of the lower water opening 252 of the lower water channel 25, and under the action of the pressure difference, the water at the lower water opening 252 of the lower water channel 25 flows towards the outlet of the water inlet channel 71, so that the fluid in the water mixing tank 20 is sucked into the lower water channel 25, and is guided out of the detergent dispensing device 100 from the first water outlet 251 along with the water guided by the water inlet channel 71, that is, guided into the washing cavity of the washing equipment.

The large diameter part 711 extends from a first end 7111 far away from the sewer channel 25 to a second end 7112 close to the sewer channel 25, that is, the water inlet channel 71 extends in the left-right direction in fig. 6, and the cross-sectional area of the large diameter part 711 decreases gradually from the first end 7111 to the second end 7112, where it should be noted that the decreasing gradually means that the cross-sectional area of the large diameter part 711 decreases gradually according to a set change value along the first direction, so that the large diameter part changes in a regular trend. According to the embodiment of the invention, the cross sectional area of the large-diameter part is gradually reduced from left to right, and the direction of the water flow entering the water inlet channel 71 is also from left to right, namely, the flow direction of the water flow is consistent with the direction of reducing the cross sectional area of the large-diameter part, so that the flow speed of the water flow in the water inlet channel is gradually increased, the water pressure is gradually reduced, the parameters of the water flow are in a continuous variation trend, the vibration and the noise generated to the detergent feeding device are reduced, and the use comfort of the detergent feeding device is improved.

That is, 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 the degree of change in water pressure are small in the course of the water flow passing through the small-diameter portion. The small diameter part 712 guides the water flow guided by the large diameter part 711 into the lower water channel 25, and forms a water flow with a lower water pressure in the lower water channel, so that the fluid in the water mixing tank 20 is quickly sucked into the lower water channel 25 from the drain port 252, and the water flow is mixed with the fluid such as detergent and flushed from the first water outlet 251 to the outside of the detergent dispensing device 100.
