Description
Technical field
The utility model belongs to washing machine field, in particular belongs to the automatic of washing machine and launches washing assisant device field.
Background technology
In the prior art, washing assisant box is equipped on washing machine, and washing assisant box has the function of dispensing automatically.But
The dispensing of most of washing assisant is by pumping the dispensing carried out, it is necessary to consume electric energy, and how to realize that quantitative launch is ability
Domain personnel will solve the problems, such as.
CN203334042U discloses a kind of washing machine of automatic dispensing additive, including inlet valve, washing tube and at least
One container for holding additive, being equipped in the washings water inlet water route between the inlet valve and washing tube one can pass through water
Stream flows through the Venturi tube for generating negative pressure, and corresponding negative pressuren zone is entered equipped with one with reservoir using negative pressure extracting additive to be washed
The liquid pumping hole in water water inlet water route is washed, metering device and the control of a detection additive injected volume are equipped between liquid pumping hole and container
The additive control valve of break-make between metering device and container processed.When launching additive, water route is intake to washing from washings
Additive in container is extracted out, measured by metering device by bucket water inlet, the negative pressure generated when passing through Venturi tube using current
Washings water inlet water route is entered by liquid pumping hole afterwards, then is flushed to by water inlet current in washing tube.Metering device be for measuring liquid,
Main measurement level is true, measures other liquid and there is the problem of inaccurate.It is detergent stoste that metering device, which measures, in this application,
Measurement is inaccurate, at the same when rinsing metering device be by separating a branch on water route intaking, current all the way directly into
Enter washing tube, be drawn by flowmeter by the principle of negative pressure of Venturi tube into water water route be flushed to washing all the way
In bucket, the water for so rinsing metering device is the wherein branch in entire water route, and current are smaller to extend water consumption measurement
The washing time of device, meanwhile, exist between flowmeter and detergent control valve and do not washed by what Venturi tube absorbed
Wash agent, during washing water quantity metering device, due to the flushed aqueous solution with detergent it is also possible into cleaning water route, i.e.,
Remaining portion washes agent forms a Xun Huan between cleaning water route and water inlet water route, it is difficult to thoroughly clean metering device dry
Only, waste detergent influences accurate measurement simultaneously.
CN106996014A discloses a kind of clothes washing method and washing machine of automatic addition detergent, the washing machine include into
Water valve, automatic detergent feeding system and washing tub are equipped with the water inlet water for carrying Venturi tube between inlet valve and washing tub
When washing machine inflow, using Venturi effect principle, a negative pressuren zone, the negative pressuren zone are formed in venturi throat 23 for road
It is communicated in constant volume valve so that negative pressure, the detergent in washing machine distributor being connected with constant volume valve are generated in constant volume valve
It is drawn into constant volume device.The negative pressure channel of Venturi tube is intake to constant volume valve in recycling, and the detergent in constant volume valve is poured
In washing tub.The present invention efficiently solves existing automatic addition detergent apparatus structure complexity, launches low precision, water inlet automatically
The problems such as time is long.This application uses constant volume chamber, and the constant volume chamber should meet volume equal to the minimum needed for washing of drum type washing machine
Detergent amount volume, and the detergent amount launched can only be the integral multiple for determining cavity volume, washing machine control program cannot be random
Setting and selection detergent amount, and extracted detergent every time and be required for rinsing constant volume chamber, when needs repeatedly extract detergent
When just need repeatedly to rinse constant volume chamber complex procedures and also take more, it is inadequate to also result in flooding time.
In the prior art, due to flowmeter can only to by the flow of water accurately detected, and to glutinous
Property very big washing assisant when being detected, it may appear that measure inaccurate situation, influence the dispensing of washing assisant.Therefore such as
The injected volume of what accurate measurement washing assisant is the technical issues of being badly in need of solving when launching washing assisant automatically.
In view of this, the utility model is proposed.
Utility model content
The purpose of this utility model is to provide the devices and its washing machine that a kind of washing machine launches washing assisant automatically.
The utility model is accomplished by the following way.
A kind of washing machine launches the device of washing assisant automatically, and described device is arranged between water inlet pipe and outlet pipe, institute
It states water inlet pipe to be connected with inlet valve, the outlet pipe is connected with tub of washing machine, is provided between water inlet pipe and outlet pipe
Venturi tube and backwashing solenoid valve have further included at least one washing assisant box, and the Venturi tube has throat, in throat
Be disposed with flowmeter between at least one washing assisant box, prestore storage device and it is at least one washing help
Agent control valve, described prestore are equipped with washing assisant branch between storage device and washing tube, the flowmeter is used for detecting
The flow of water, the washing assisant to prestore in storage device enter washing tube by washing assisant branch.
Preferably, the volume of the storage device that prestores launches the maximum amount of body of washing assisant automatically more than washing machine single
Product.
Preferably, check valve is provided on washing assisant branch road, washing assisant may only unidirectionally flow into washing tube.
The first wash auxiliary agent pipe of the storage device between flowmeter and washing assisant box that prestore.
A container of the storage device between flowmeter and washing assisant box that prestore.
The storage device that prestores is the washing assisant pipe and container being arranged between flowmeter and washing assisant box.
The flowmeter is flowmeter, and the flowmeter is connected with washing machine controller, described to wash
Clothing machine controller is connected with washing assisant control valve.
A kind of washing machine has the device of foregoing automatic dispensing washing assisant.
The advantages of the utility model:Since general washing assisant stickiness is larger, and flowmeter is in measurement liquid
It, can the accuracy decline because of the variation for flowing through liquid viscosity during flow.In the utility model, by setting the pre- of washing assisant
Storage device and washing assisant branch avoid washing assisant from flowing through flowmeter, and washing assisant in the storage device that prestores
Volume, it is identical with the volume that the water for flowing through flowmeter is pumped from the storage device that prestores, by the volume generation for measuring water
For the volume of metering washing assisant, so as to add the accuracy of flowmeter detection, the dispensing of washing assisant is improved
Efficiency, reduces washing assisant, and the waste of washings reduces the washing assisant release time.
