Antidrip water dispenser water valve

Technical field

The utility model relates to a kind of water dispenser member, relates in particular to a kind of refrigerator water dispenser water valve.

Background technology

Along with the universalness of refrigerator as a kind of daily household electrical appliance, refrigerator has become the requisite household electrical appliance of average family.In order to improve the service efficiency of refrigerator, the multifunction of refrigerator becomes the research and development focus of refrigerator manufacturers, arises at the historic moment under such environment setting up water dispenser on the refrigerator.But at present the water valve of water dispenser is owing to adopt traditional water dispenser design, still has a small amount of drinking water to remain in the pipeline between valve and the delivery port behind valve closing, and can make the sanitary conditions of refrigerator be affected from the pipeline drippage after the user leaves.

The utility model content

The utility model has the phenomenon that continues water clock after water intaking at present water fountain effluent mouth, a kind of antidrip water dispenser water valve is provided, comprise switch, water inlet, delivery port and inner chamber, described inner chamber communicates with water inlet and delivery port, it is characterized in that: also include the antidrip member, described antidrip member comprises connection chamber, mandrel and solenoid, described mandrel comprises the chassis, push away handle, described mandrel chassis and connection chamber coupling, fixedly connected with the chassis in the described handle top that pushes away, tail end and solenoid join, by solenoid tractive and then drive chassis horizontal movement in connection chamber, described electromagnetic coil circuit is controlled by switch, and described connection chamber communicates with inner chamber, engages each other closely.After original water dispenser water valve re-entrant portion was set up the antidrip member, after the client finished from the water dispenser water intaking, residual surplus water entered in the cavity by the negative pressure that the mandrel pull produces, and when fetching water next time, flowed out by the disappearance of negative pressure again.In order in cavity and connection chamber, to produce negative pressure, the mandrel that is arranged on wherein just must be by pumpback, the power of this pumpback is provided by solenoid, owing to had magnetic after the solenoid energising, can produce suction to the mandrel of metal material, thereby attract to push away handle to the external lateral movement of connection chamber, and then drive the chassis and move laterally, reach and make the effect that produces negative pressure in the cavity, the water section that is sent to drinking-water is drawn back, thereby guarantee that the mouth of pipe does not have weeping after client's water intaking.Certainly, for the better fit valve switch, the circuit of solenoid is controlled by this switch also, when switch opens, the circuit of electromagnetism circuit is opened, current normally pass through, when switch cuts out, and the closing of circuit of electromagnetism circuit, produce magnetic force, the traction mandrel is as movement outside, and the part current are subjected to mandrel effect pumpback and go into cavity, continues water clock after preventing to close water valve.

When making that the solenoid circuit is opened, mandrel can better reset, do not use thereby do not influence next time, the inventor is provided with elastic device, and described elastic device is between mandrel chassis and connection chamber inwall, because in the middle of mandrel pumpback process, elastic device produces elastic deformation, so when this external force lost, the restoring force of elastic device promoted mandrel and gets back to the home position, thereby not only the surplus water of last time is released, and for the surplus water of water intaking back pumpback part is ready next time.For the ease of producing and implementing, the elastic device here can be selected according to actual conditions, and preferred a kind of mode is a spring.

As another improvement of the present utility model, the inventor has set up the sealing ring that embeds on the mandrel chassis, described sealing ring is embedded in mandrel chassis side surface, though chassis and connection chamber cavity mate, but owing to be hardened member, its air-tightness is poor, embeds the sealing ring of rubber material on the chassis, can effectively increase the air-tightness of chassis and connection chamber inwall, guarantee the stable of cavity internal gas pressure.

In sum, the beneficial effects of the utility model are conspicuous.After adopting the technical solution of the utility model, the water clock of surplus water takes place effectively to prevent water dispenser to close afterwards, and is simultaneously easy and simple to handle, synchronous with the switch of water valve, do not influence the normal use of water valve.

The specific embodiment

Embodiment 1

On the water dispenser water valve that comprises switch 1, water inlet 2, delivery port 3, inner chamber 4 originally, set up an antidrip member, this antidrip member comprises connection chamber 5, spring 6, sealing shroud 7, chassis 8, pushes away handle 9 and solenoid 10, make and concavo-convex the agreeing with of outer wall of cavity 4 and connection chamber 5 solenoid 10 is connected with switch 1.When the user fetched water, switch 1 was opened, and current are flowed into by water inlet 2 from water tank, and flowed out by delivery port 3, and this moment, the circuit of solenoid 10 was also opened, and chassis 8 is positioned at initial position, and the chassis is identical with space air pressure and atmospheric pressure that cavity forms.When water intaking finishes, close switch 1, the closing of circuit of solenoid 10, energising produces magnetic force, what attract metal material pushes away handle 9 to solenoid one lateral movement, owing to push away handle 9 and chassis 8 is structure as a whole, so drive chassis 8 also to the direction motion of solenoid 10, at this moment, air in the inner chamber 4 reduces rapidly, and air pressure descends, and forms negative pressure, the remaining drinking water of part is subjected to the atmospheric pressure effect, is pressed in inner chamber 4 and part connection chamber 5 cavitys.Since chassis 8 motions, the spring 6 of extruding between chassis 8 and connection chamber 5, and elastic deformation takes place in spring 6.When fetching water once more, open switch 1, thereby make the circuit of solenoid 10 open, because circuit is opened, consequent magnetic force disappears, push away handle 9 and original initial position is got back on chassis 8, spring 6 is owing to produce elastic deformation, so when external force disappears, the restoring force of spring 6 impels chassis 8 and pushes away handle 9 and be returned to initial position faster, the surplus water that remains in the cavity is got rid of, and further carried out the preparation of the surplus water of next suction and pumping.
