It should be noted that the cabinet door 100 of the dishwasher includes an inner door and an outer door stacked inside and outside, and the detergent dispensing structure 200 is disposed on an outer side surface of the inner door facing the outer door; a control panel 300 is generally disposed at an area adjacent to the upper end of the cabinet door 100, and various control keys or knobs, a display screen for displaying the working state of the dishwasher, and the like are disposed on the control panel 300; one end of the putting channel 210 is connected in the inner container of the dish washing machine, the other end is connected with the outside, when a related control device of the dish washing machine receives a detergent putting instruction, the driving mechanism 230 can be controlled to drive the valve to move so as to open the putting channel 210, then, the powdery detergent or the block detergent can be put out from the putting port 211 through the putting channel 210, and meanwhile, after the valve is opened, water vapor, condensed water and the like in the dish washing machine can enter the putting channel 210 when the water vapor, the condensed water and the like enter the putting channel 210, particularly the closed section; like this, after the operation of dish washer, vapor can form the comdenstion water and attach to the inner wall of puting in passageway 210, can lead to powdered detergent or massive detergent caking or the adhesion in puting in passageway 210 under long-term the accumulation to lead to the detergent to put in the volume inaccurate, block even and put in passageway 210, seriously influence the automatic reliability of puting in of detergent.

Based on the structural design, in the embodiment, since the dehumidifying device 240 is disposed beside the feeding channel 210, and the dehumidifying device 240 is located on the side of the first valve 220 away from the feeding port 211, after the first valve 220 is opened, a small amount of water vapor entering the inner sealing section 212 of the feeding channel 210 can permeate the dehumidifying hole 243 to be absorbed by the dehumidifying part 241, so as to achieve the purpose of dehumidifying the feeding channel 210, and thus, the drying of the inner wall of the feeding channel 210, especially the inner sealing section 212, can be maintained, so that the powdery detergent or the massive detergent is not easy to agglomerate or adhere, thereby ensuring the smooth feeding of the detergent, and greatly increasing the automatic feeding reliability of the detergent feeding structure 200.

Referring to fig. 1, in the present embodiment, the detergent dispensing structure 200 further includes a second valve 260, the second valve 260 and the first valve 220 are spaced and arranged in parallel, and are located on a side of the first valve 220 away from the dispensing opening 211; the dehumidifying apparatus 240 is disposed between the first valve 220 and the second valve 260. Specifically, in the present embodiment, the first valve 220 and the second valve 260 move in opposite directions, and at least one of the first valve 220 and the second valve 260 closes the dispensing passage 210, so that when the second valve 260 is closed, the inner sealing section 212 can be divided into a first section 212a away from the first valve 220 and a second section 212b adjacent to the first valve 220. Of course, in other embodiments, only the first valve 220 may be provided, and the opening and closing of the throwing channel 210 may also be controlled, but in this embodiment, the water vapor in the dishwasher liner may be further prevented from directly entering the whole throwing channel 210 by providing the motion cooperation between the first valve 220 and the second valve 260 which are spaced in parallel. In addition, in other embodiments, the dehumidifying device 240 can be disposed on a side of the second valve 260 away from the input port 211, but in this embodiment, when the dehumidifying device 240 is disposed between the first valve 220 and the second valve 260, it is not only beneficial to save the internal installation space, but also can obtain better dehumidifying effect.

The movement process and the matching relationship between the two valves will be described in the following with the actual detergent dispensing process. In this embodiment, the detergent dosing comprises three phases: in the first stage, the first valve 220 and the second valve 260 close the feeding passage 210, and the detergent slides down from the first section 212a to the second valve 260; in the second stage, the second valve 260 moves back to open the dispensing channel 210, so that the detergent can slide down from the second section 212b onto the first valve 220, and then the second valve 260 moves again to close the dispensing channel 210; in the third stage, the first valve 220 is opened, so that the detergent slides from the second section 212b to the outer passage 213, and is finally discharged from the discharge port 211, and then the first valve 220 moves to close the discharge passage 210, thereby completing the entire detergent discharge process. As can be seen from the above process, the design of the first valve 220 and the second valve 260 can avoid simultaneous release of the first section 212a, the second section 212b and the outward passage section 213 in the dispensing passage 210, so as to avoid water vapor from directly entering the longer first section 212a and staying at most in the second section 212b between the first valve 220 and the second valve 260, and a moisture absorption device communicated with the second section 212b is further provided at this position, so that water vapor entering the second section 212b can be quickly absorbed by the moisture absorption member in the moisture absorption device, thereby ensuring that the inner wall of the second section 212b can be kept in a dry state for a long time; meanwhile, as the second section 212b is generally shorter, the amount of water vapor which can enter is smaller, so that the service life of the moisture absorbing part is longer, and the trouble of frequently replacing the dehumidifying part 241 is effectively avoided.
