Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
Embodiment 1:
Refering to Figure 1, the present embodiment provides a kind of liquid additive delivery devices, using washing machine as application
Example, including additive storage box 1, water chamber 2, additive chamber 3 and mixing drum 4 (being herein inner tank of washing machine).
Be provided in water chamber 2 water inlet 5 be connected to the water inlet pipe 6 of mixing drum 4, be provided with blade wheel 7 in water chamber 2,
When water inlet 5 is intake, water flow driving blade wheel 7 is rotated.Especially, it should be noted that water inlet 5 herein is not washing machine
Total water inlet is intended only as drawing a tributary of additive, therefore does not have to worry the case where can not carrying out clear water washing.
It is provided with pipette 8 on additive chamber 3 and extends to additive storage box 1 with the branch pipe 9 of water inlet pipe 6, pipette 8 is connected to
Below the liquid level of middle liquid additive, it is provided with gear pump 10 in additive chamber 3, flow controller 11 is provided on branch pipe 9, is entered
On-off valve 18 is provided at the mouth of a river 5, flow controller 11 is electrically connected with on-off valve 18, when the judgement of flow controller 11 reaches target
After injected volume, the closing of on-off valve 18 is delivered a signal to, water inlet 5 stops water inlet, and device runs out of steam source.The shaft of blade wheel 7
12 stretching water chambers 2 simultaneously protrude into additive chamber 3, and the driving shaft of gear pump 10 is directly connected with shaft 12, thus gear pump 10 by
Blade wheel 7 drives.Herein it should be noted that when shaft 12 passes through water chamber 2 and additive chamber 3, it is necessary to assure cavity sealing
Property, therefore water-sealed bearing 13 is provided with for shaft 12 in the outside of water chamber 2, additive chamber 3.
It is stored with liquid additive in additive storage box 1, liquidometer 14, liquidometer are provided in additive storage box 1
14 are electrically connected with alarm module, when liquidometer 14 detect liquid additive liquid level be not higher than pipette 8 port when, alarm
Module is warned, so that cleaning solution is replenished in time.
In addition, water inlet pipe 6, branch pipe 9 are arranged diagonally downward to reduce water inlet power demand.
Thus, it need to only be intake by water inlet 5, driving blade wheel 7 rotates, and then gear pump 10 is driven to rotate, and can be realized
Additive imports in mixing drum 4 together by being sucked up in water inlet pipe 6 in additive storage box 1, with water inlet, without additional dynamic
Power, and when additive injected volume is up to standard, on-off valve 18 is controlled by flow controller 11 and is closed, cutting water inlet stops launching
Additive.
Therefore for above-mentioned delivery device, the present embodiment also proposed a kind of liquid additive putting mode comprising with
Lower step:
1) it is whether sufficient that additive reserves in additive storage box 1 are detected, if so, entering in next step；If it is not, then reporting
It is alert；
2) water inlet of water inlet 5 drives blade wheel 7 and gear pump 10 to rotate, and the additive in additive storage box 1 is inhaled
It takes and imports water inlet pipe 6；
3) by the flow controller 11 on branch pipe 9, judge whether that reaching target launches addition agent dose, if it is not, then after
Continuous water inlet；If so, control water inlet 5 is closed.
Thus, it could be seen that the liquid additive delivery device and method have a characteristic that
1) structure is simple, and control is easy；
2) power source by water inlet as device, the negative pressure of additive chamber 3 can be realized without extra power；
3) additive timing and diversity are improved；
4) intelligent higher, automation control, can be according to user demand setting, additive types and washed clothing kind
The factors intelligent selection washing procedure such as class, weight, and according to selected washing procedure, the automatic addition for adding most reasonable volume
Agent avoids the excessive or very few situation of artificial addition additive, while having saved resource, alleviates dirt of the washing water to environment
Dye.
Embodiment 2:
Please refer to shown in Fig. 2, the present embodiment the difference from embodiment 1 is that, gear pump 10 is not directly fixed on shaft
It on 12, but is driven indirectly by transmission mechanism, such as speed-changing gear box is specifically provided between blade wheel 7 and gear pump 10
Gearbox 17 is provided with first gear 15 and second gear 16 in gearbox 17, and shaft 12 and first gear 15 are sequentially connected, tooth
The driving shaft and second gear 16 of wheel pump 10 are sequentially connected, 16 engaged transmission of first gear 15 and second gear.It is arranged in this way
It is advantageous in that, according to water inlet power, selects suitable transmission ratio, adjust the suction of additive chamber 3.
Embodiment 3:
It please referring to shown in Fig. 3, the present embodiment on the basis of embodiment 1, is extended as multiple additive storage boxes 1,
Each additive storage box 1 is correspondingly arranged a water chamber 2 and an additive chamber 3.When washing of drum type washing machine clothing, can often it use
More than one additive, such as pre- washing lotion, main washing lotion, softener, regulator, and timesharing sequence is needed to use, at this moment by several times
Add it is not only troublesome, and dosage be difficult to control.It, can be with so carry out examples in the present embodiment with two additive storage boxes 1
It realizes multiple additives simultaneously or the operation successively added, has to embody this delivery device and launch the diversified function of additive
Energy.
To sum up, above-mentioned liquid additive delivery device structure is simple, and principle is ingenious, drives blade wheel and then band by water inlet
The rotation of movable tooth wheel pump provides power to extract additive, is not necessarily to additional negative pressure source, and do not influence to intake, passes through flow controller
Additive injected volume is controlled, in addition, on this basis can be according to washing procedure or washing species, quantity etc., by collecting
At intelligent control system automatically select required additive types and launch suitable dose, high degree of automation, intelligence are strong,
Technology, which is launched, for liquid additive provides new thinking.
Above embodiments only elaborate the basic principles and features of the present invention, and the utility model is not by above-mentioned example
Limitation, on the premise of not departing from the spirit and scope of the utility model, the present invention has various changes and changes, these changes
