Detailed Description

The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and not limited to the following examples.

Example 1.

Referring to fig. 1 to 17, the automatic dispensing apparatus of the present embodiment includes a dispensing cartridge 1, a dispensing unit 2, a dispensing pump 3, a cover 20, an ejector unit 4, a drain cartridge 5, and a fixing device 6.

The dispensing box 1 in this embodiment has a first chamber 11 and a detergent chamber 12, wherein the detergent chamber 12 is used for placing detergent, the first chamber 11 and the detergent chamber 12 are independent chambers, and a dispensing opening 121 is arranged at the bottom of the detergent chamber 12.

The dispensing unit 2 in this embodiment has a water path 21 communicating with the detergent chamber 12, a liquid outlet channel 22 communicating with the water path 21, and a water inlet 23 communicating with the liquid outlet channel 22, wherein the water inlet 23 is configured such that external clean water enters the liquid outlet channel 22.

The dispensing pump 3 in this embodiment is configured to pump the liquid in the first chamber 11, and flow into the waterway 21 through the liquid outlet channel 22, and after the liquid in the first chamber 11 enters the liquid outlet channel 22, the liquid is mixed with the clean water entering from the water inlet 23, so as to dilute the liquid. The dispensing pump 3 itself is of prior art and will not be described in detail here.

The liquid outlet channel 22 in this embodiment includes a first section 221 and a second section 222, wherein the second section 222 is closer to the waterway 21 than the first section 221, i.e. the second section 222 is communicated with the waterway 21, and a water blocking portion 223 is disposed in the second section 222, and the water blocking portion 223 may be configured to form a vortex on the liquid flowing therethrough so as to perform sufficient mixing dilution.

The second section 222 in this embodiment has a smaller cross-sectional area at the water blocking portion 223 than the first section 221. Therefore, when flowing through this, the pressure increases, which is more advantageous for forming a vortex, and on the other hand, after the pressure increases, the liquid is prevented from remaining at the water blocking portion 223.

The water blocking portion 223 in the present embodiment has a transition surface 2231 and a guiding surface 2232, and the transition surface 2231 and the guiding surface 2232 are cambered surfaces.

Specifically, the inflow section 211 and the outflow section 212 in this embodiment are two groups, that is, the cross-sectional area of the first section 221 is larger than the cross-sectional area of a single group of the inflow sections 211. Thus, the liquid is pressurized as it enters the inflow section 211 from the first section 221, avoiding or reducing the liquid residue in the waterway 21.

The waterway 21 in this embodiment further includes a dispensing area 213, and the dispensing area 213 is configured corresponding to the detergent chamber 12, specifically, the dispensing area 213 is disposed at an upper portion of the detergent chamber 12. The drop zones 213 are each in communication with two sets of outflow sections 212. The delivery area 213 has a first area 2131, a second area 2132, and a third area 2133, wherein the first area 2131 and the second area 2132 are located in the extending direction of the two sets of outflow segments 212, respectively, and the third area 2133 communicates with the first area 2131 and the second area 2132. Preferably, the first area 2131, the second area 2132 and the third area 2133 are provided with holes 2134, and after the liquid enters the putting area 213, the liquid flows into the washing powder cavity 12 through the holes 2134 of the first area 2131, the second area 2132 and the third area 2133, so that the liquid uniformly flows into the washing powder cavity 12, and the situation that the washing powder is partially caked and is not washed cleanly is avoided.

Further, the other side of the hole 2134 opposite to the dispensing area 213 is provided with a pipe 2135, so that the liquid entering the hole 2134 has directionality to prevent the liquid from flowing along the lower wall of the dispensing area 213. Preferably, at least part of the inner wall of the hole 2134 has a slope 2136, which slope 2136 is inclined with respect to the up-down direction of the drop zone 213. Optionally, the bevel 2136 points to an intermediate position in the lower part of the drop zone 213.

The washing powder chamber 12 in this embodiment has a first area 122 corresponding to the dispensing area 213 and a second area 123 communicating with the first area 122, and the bottom of the second area 123 opposite to the other side of the first area 122 is provided with the dispensing opening 121.
