Embodiment 1

[0026] see figure 1 As shown, this embodiment provides a liquid additive dispensing device, taking a washing machine as an example of an application, including an additive storage box 1, a water supply chamber 2, an additive chamber 3 and a mixing cylinder 4 (here, the inner cylinder of the washing machine).

[0027] The water supply chamber 2 is provided with a water inlet 5 and a water inlet pipe 6 connected to the mixing cylinder 4. The water supply chamber 2 is provided with a blade wheel 7. When the water inlet 5 enters water, the water flow drives the blade wheel 7 to rotate. It should be noted that the water inlet 5 here is not the main water inlet of the washing machine, but only serves as a branch for absorbing additives, so there is no need to worry about the situation that washing with clean water cannot be performed.

[0028] The additive chamber 3 is provided with a suction pipe 8 and a branch pipe 9 connected to the water inlet pipe 6. The liquid suction pipe 8 e...

Embodiment 2

[0042] see figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the gear pump 10 is not directly fixed on the rotating shaft 12, but is indirectly driven by a transmission mechanism, such as a gear box, specifically, between the vane wheel 7 and the gear pump 10 A gearbox 17 is provided, and the gearbox 17 is provided with a first gear 15 and a second gear 16, the rotating shaft 12 is in transmission connection with the first gear 15, the drive shaft of the gear pump 10 is in transmission connection with the second gear 16, and the first gear 15 Engage with the second gear 16 for transmission. The advantage of such setting is that, according to the water inlet power, an appropriate transmission ratio is selected to adjust the suction of the additive chamber 3 .

Embodiment 3

[0044] see image 3 As shown, on the basis of Embodiment 1, this embodiment is expanded into a plurality of additive storage boxes 1 , and each additive storage box 1 is correspondingly provided with a water supply chamber 2 and an additive chamber 3 . When washing clothes in a washing machine, more than one additive is often used, such as pre-washing liquid, main washing liquid, softener, conditioner, etc., and it needs to be used sequentially. At this time, it is not only cumbersome to add in batches, but also the dosage is difficult to control. Therefore, in this embodiment, two additive storage boxes 1 are used as an example, and multiple additives can be added simultaneously or sequentially, so as to reflect that the dispensing device has the function of dispensing diversified additives.

[0045]To sum up, the above-mentioned liquid additive dispensing device and its dispensing method are simple in structure and ingenious in principle. The impeller is driven by the water ...

Abstract

The invention discloses a liquid additive putting device. The liquid additive putting device comprises an additive storage box, a water supply cavity and an additive cavity, wherein the additive storage box is used for storing a liquid additive; the water supply cavity is provided with a water inlet and a water inlet pipe communicated with a mixing cylinder, the water supply cavity is internally provided with a blade wheel, the blade wheel is driven by entered water of the water inlet, and the water inlet is provided with an on-off valve; the additive cavity is provided with a liquid suction pipe and a branch pipe communicated with the water inlet pipe, the liquid suction pipe extends to the lower portion of the liquid level of the liquid additive in the additive storage box, the additivecavity is internally provided with a gear pump, the gear pump is driven by a rotating shaft of the blade wheel, and the branch pipe is provided with a flow controller. The invention further disclosesa liquid additive putting method. The entered water drives the blade wheel to drive the gear pump to rotate to provide power for extracting the additive, an additional negative pressure source is notneeded, and the putting amount is accurately controlled.

Description

technical field [0001] The invention relates to a liquid distributing device, in particular to an additive injecting device and an injecting method equipped on electric washing machines such as electric washing machines and electric dishwashers. Background technique [0002] For washing equipment such as electric washing machines and electric dishwashers that use liquid additives, when adding liquid additives (such as detergents, softeners, softeners, sterilizing solutions, etc.), the user generally stores the liquid additives to be injected in a designated place in advance. Inside the container, the washing equipment flushes it into the washing drum through water flushing or other mechanical methods according to the washing process. The dosage of this method depends on the operation of the user, and at the same time, additives need to be added to the container during each washing process. In order to reduce the user's troublesome operation, and even to automatically adjust...
