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 only needs to 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 process that the washing apparatus controls the detergent container 3 to dispense the liquid into the liquid passing channel 21. Under the condition that the liquid detergent container 3 contains the liquid such as the liquid detergent, the softener, the disinfectant, the perfume and the like, 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 liquid detergent container 3 contains the liquid such as the liquid detergent, the softener, the disinfectant, the perfume and the like. In case the detection assembly 4 detects that there is no fluid flowing through the liquid passage 21, the detection assembly 4 can determine that there is no fluid 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 assembly 4 can determine that the detergent container 3 needs to be replaced or needs to be supplemented 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.
The embodiment of the invention provides a detergent putting device which comprises a distributor box, a detergent box and a detection assembly. The distributor box is provided with at least one accommodating groove for accommodating a detergent container, a water mixing groove is arranged at the bottom of the detergent box, a liquid passing channel communicated with the water mixing groove is arranged at the rear end of the detergent box, the detergent container is connected with the liquid passing channel, and a detection assembly is arranged in the liquid passing channel to detect whether detergent flows to the liquid passing channel or not. According to the embodiment of the invention, the detection device is arranged in the liquid passing channel, compared with the mode that the detection device is arranged in the detergent container, the detection device does not need to be constantly contacted with the fluid in the detergent container, the fluid is contacted with the detection device only under the condition that the fluid in the detergent container flows to the liquid passing channel, and the detection device can detect that the fluid is remained in the detergent container; the fluid flowing through the detection device can flow to the water mixing tank communicated with the bottom of the liquid passing channel along the liquid passing channel under the action of gravity, so that the fluid cannot stay on the detection device, the detection of the fluid by the detection device for the next time is facilitated, the detection sensitivity of the detection device is improved, and the problem that the detection device has poor fluid induction in a detergent container in a detergent putting device is solved.
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, where 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 a thread manner, and the probes 40 can be permanently fixed with the first end wall 221 by a welding manner. Whatever the manner of connecting the probe 40 and 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 into 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 the 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; when the fluid in the detergent container flows into the liquid passing 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 liquid passing 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 in the same group of probes 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 passing channel, 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-back direction, wherein the front side of the first end wall 221 is the liquid passing channel 21, and the dispensing pump 5 is arranged on the side of the first end wall 221 far away from the connecting piece 23, that is, the dispensing pump 5 is arranged on the back side of the first end wall 221. In the embodiment of the present invention, the dispensing 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 22 can be reduced, thereby increasing the fluid storage space and reducing the interference on fluid conduction.
The dispensing 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 dispensing pump 5, and two or more suction channels may also be disposed inside the dispensing pump 5, in the case that a plurality of suction channels are disposed inside the dispensing 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 holding grooves disposed in the dispenser box 1, that is, the number of suction channels is the same as the number of detergent containers disposed. 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. The first probe 401 and the second probe 402 are disposed at an interval, the first probe 401 is close to the liquid outlet 52 relative to the second probe 402, it should be noted that, in the case of disposing multiple sets of probes, the number of sets of probes corresponds to the number of liquid outlets, one liquid outlet corresponds to one set of probes, and the first probe 401 in the set of probes is close to the liquid outlet relative to the 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 probes is close to the liquid outlet relative to 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 of detection that can be accurate. The detection sensitivity and accuracy of the detection device are improved.
In some embodiments, as shown in FIG. 4, the two probes 40 in each set of probes 40 are staggered. For example, in the embodiment shown in fig. 4, two sets of probes are provided, namely a first set of probes 41 and a second set of probes 42, 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-sections of the first probe 401 and the second probe 402 forms a predetermined 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.
In some embodiments, as shown in fig. 4, the direction of the connecting line of the two probes (see the direction shown by the dashed line in fig. 4) forms a first angle θ with the vertical direction (see the direction shown by the dashed line in fig. 4). The connecting line of the two probes indicates a connecting line of 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 the 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 through to the liquid outlet is great, under the too little condition of the direction of the connecting wire of two probes and vertical direction's contained angle, the liquid that the liquid outlet flowed out is influenced and difficult the flowing to the second probe by the water conservancy diversion of first probe. In the embodiment of the invention, the first included angle theta 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.

A first probe 401 of the second set of probes 42 is positioned adjacent to the second exit orifice 522 relative to the second probe 402. And the first probe 401 in the second group of probes 42 is close to the edge of the water mixing tank 20 in the left-right direction relative to the second probe 402, it should be noted that, in the embodiment of the present invention, the positional relationship between the first probe 401 and the second probe 402 in the left-right direction is related to the positional relationship between the liquid outlets in the left-right direction, and the positional relationship between the first probe, the second probe and the center of the water mixing tank can satisfy the requirement of guiding the fluid to flow toward the center of the water mixing tank instead of guiding the fluid to flow toward the edge of the water mixing tank. According to the embodiment of the invention, the second probe in the same group of probes is opposite to the first probe, so that the fluid can be guided to flow towards the center direction of the water mixing tank, the risk of fluid residues in the liquid passing channel can be reduced, and the utilization rate of the fluid such as detergent can be improved.
