For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0048] Embodiment one
[0049] As Figures 1 to 7 shown, an additive dispensing device is provided in the embodiment of the present application, comprising:
[0050] The liquid storage cavity 111 is used for containing the additive;
[0051] The premix water supply waterway 31, and the water outlet 311 of the premix water supply waterway 31 is communicated with the liquid storage cavity 111;
[0052] The suction assembly 2, and the liquid inlet 21 of the suction assembly 2 is communicated with the liquid storage cavity 111;
[0053] The dispensing water supply waterway 32, and the liquid outlet 22 of the suction assembly 2 is communicated with the dispensing water supply waterway 32.
[0054] In the above scheme, the concentrated additive in the liquid storage cavity 111 is diluted by the water inlet of the premix water supply waterway 31, and then the diluted additive is sucked into the dispensing water supply waterway 32 by the suction assembly 2, realizing automatic dispensing of the diluted additive into the washing drum. The perfume for clothes scenting can be automatically dispensed into the washing drum, realizing precise control of the scent concentration in the washing drum and improving the scenting effect of the clothes.
[0055] As Figures 1 to 3 shown, in the embodiment, the premix water supply waterway 31 and the dispensing water supply waterway 32 are connected in parallel, the dispensing water supply waterway 32 has a water inlet 321, a first water outlet 322 and a second water outlet 323, and the dispensing water supply waterway 32 is communicated with the liquid outlet 22 of the suction assembly 2 through the first water outlet 322.
[0056] In the above scheme, after the premix diluted perfume solution is sucked into the dispensing water supply waterway 32 by the suction assembly 2, water is supplied into the dispensing water supply waterway 32, and under the action of the water flow, the perfume solution flows to the second water outlet 323 and finally acts on the clothes, realizing the purpose of precise control of the perfume concentration.
[0057] As Figures 1 to 3 shown, in the embodiment, the second water outlet 323 is arranged upstream of the dispensing water supply waterway 32, and the second water outlet 323 is arranged downstream of the dispensing water supply waterway 32.
[0058] In the above scheme, the second outlet 323 is located upstream of the water supply channel 32, relative to the inlet 321 of the water supply channel 32, so that the water flowing into the water supply channel 32 is fully mixed with the fragrance solution pumped into the water supply channel 32 to form a uniform fragrance solution, which can better act on the clothes.
[0059] like Figure 3 As shown in this embodiment, the water supply channel 32 is provided with a diversion guide rib 324 extending from the inner wall of one side of the water channel to the opposite side. There is a gap between the extended end of the diversion guide rib 324 and the inner wall of the water channel to allow water to flow through. The gap not only ensures that the water supply channel 32 is unobstructed, but also prolongs the time that the water in the water supply channel 32 stays in the water channel, so that the water flowing into the water supply channel 32 is fully mixed with the diluted fragrance solution.
[0060] Preferably, the extended end of the diversion guide rib 324 is inclined or bent in the downstream direction of the water supply channel 32 to further reduce the water flow velocity upstream of the water supply channel 32 and ensure the mixing time between the fragrance water solution pumped into the water supply channel 32 and the water flowing into the water supply channel 32.
[0061] More preferably, the first outlet 322 is located on one side of the extension end of the diversion guide rib 324. When the water flow from the water supply channel 32 flows through the gap between the extension end of the diversion guide rib 324 and the inner wall of the water channel, the flow velocity increases due to the narrowing of the flow channel, thereby counteracting the fragrance solution stored on one side of the extension end of the diversion guide rib 324, so that the fragrance solution obtained after the two are mixed is more uniform.
[0062] like Figure 3 As shown, in this embodiment, the diversion guide rib 324 is integrally formed with the inner wall of one side of the water supply path 32 to divide the water supply path 32 into a first outlet branch 32a connected to the inlet 321 of the water supply path 32 and a second outlet branch 32b connected to the second outlet 323. The diversion guide rib 324 divides the water supply path 32 into outlet branches that are connected to each other and have different water flow directions, thereby adjusting the water flow rate more precisely so that the fragrance solution is mixed more thoroughly, thereby controlling the fragrance density in the washing drum and preventing the fragrance of clothes from being too light and failing to achieve the purpose of enhancing the fragrance of clothes, or the fragrance of clothes from being too strong and causing user aversion.
[0063] Preferably, the first water outlet 322 is located on the first water outlet branch 32a or the second water outlet branch 32b, and the second water outlet 323 is located on the second water outlet branch 32b, so that the fully mixed fragrance solution flows out from the second water outlet 323 located on the second water outlet branch 32b and finally acts on the clothes in the washing drum to enhance fragrance and remove odors.
[0064] More preferably, the first outlet 322 is located downstream of the first outlet branch 32a, and the second outlet 323 is located downstream of the second outlet branch 32b, so that the pumped fragrance solution is fully mixed with the water flow of the first outlet branch 32a before flowing into the second outlet branch 32b.
[0065] like Figure 3 As shown, in this embodiment, the extension direction of the diversion guide rib 324 is the same as the water flow direction at the outlet end of the first water outlet branch 32a, and the water flow direction at the outlet end of the first water outlet branch 32a is opposite to the water flow direction at the inlet end of the second water outlet branch 32b. By adjusting the water flow rate and direction of the first water outlet branch 32a and the second water outlet branch 32b through the extension direction of the diversion guide rib 324, the concentration of the final fragrance solution can be controlled more precisely, that is, the effect of adding fragrance to clothes meets the user's psychological expectations.
[0066] like Figures 1 to 3 As shown, in this embodiment, the first water outlet branch 32a is a U-shaped waterway that changes the direction of water flow, and the second water outlet branch 32b is a long strip waterway. It is not only simple in structure and easy to process, but also easy to adjust the flow rate and direction of water in the water supply channel 32. It can also better avoid the siphon phenomenon in the water supply channel 32.
[0067] like Figures 1 to 3 As shown, in this embodiment, the premixed water supply path 31 and the dispensing water supply path 32 are connected in parallel. The outlet 311 of the premixed water supply path 31 is located above the storage chamber 111. Water is introduced into the storage chamber 111 through the premixed water supply path 31 to dilute the perfume stored in the storage chamber 111 and at the same time flush the storage chamber 111 to avoid perfume residue and waste of resources.
[0068] Preferably, the premixed water supply circuit 31 has multiple water outlets to form a shower head structure, which is simple in structure and easy to process, and enables rapid dilution of perfume stored in the liquid storage chamber 111.
[0069] Through the above-mentioned additive dispensing device, the premixed water supply channel 31 dilutes the additive stored in the liquid storage chamber 111. The diluted additive is then drawn into the dispensing water supply channel 32 via the suction component 2. Water is then introduced into the dispensing water supply channel 32 to dispense the diluted additive into the washing drum. This is especially useful for perfumes used to enhance the fragrance of clothes. The additive dispensing device can not only automatically dispense perfumes but also precisely control the concentration of the perfumes to ensure their effectiveness.
