Detailed Description
Referring to fig. 1 in combination, an embodiment of the present invention provides a drainage apparatus, including: the drainage pipeline 1 is communicated with the water using equipment 2 and is used for draining water from the water using equipment 2; and the vacuum pump 3 is communicated with the drainage pipeline 1 and is used for vacuumizing the drainage pipeline 1. .
The utility model discloses a water equipment can be dish washer, water works such as cleaning machine, needs the equipment of carrying out the drainage.
the utility model discloses at the drainage pipeline tail end of water equipment with the vacuum pump, when the residual water can't thoroughly be drained to the drain pump, with whole drainage pipeline evacuation processing, utilize the back pressure principle that vacuum state and normal atmospheric pressure produced to the inside residual water evacuation of water equipment to the residual water of solving water equipment leads to inside to breed bacterium, smelly peculiar smell scheduling problem.
In this embodiment, the drainage device further includes an electromagnetic valve set, and the electromagnetic valve set is disposed on the drainage pipeline 1 and is used for closing or opening the drainage pipeline 1. The electromagnetic valve group comprises a first electromagnetic valve 4; the first solenoid valve 4 is arranged at one end of the drainage pipeline 1 close to the water consumption device 2, and/or the solenoid valve group comprises a second solenoid valve 5, and the second solenoid valve 5 is arranged at one end of the drainage pipeline 1 far away from the water consumption device 2. The two electromagnetic valves are respectively arranged at two ends of the drainage pipeline 1 and can be respectively closed to seal the drainage pipeline 1; the two electromagnetic valves are opened simultaneously, the drainage pipeline 1 is unblocked, the inner cavity of the water using equipment is communicated with the outside through the drainage pipeline 1, and water in the inner cavity of the water using equipment can flow out along the drainage pipeline 1; only the first electromagnetic valve 4 is opened, the drainage pipeline 1 is communicated with the inner cavity of the water using equipment, and water in the water using equipment can flow into the drainage pipeline 1; only the second electromagnetic valve 5 is opened, the drainage pipeline 1 is not communicated with the inner cavity of the water using equipment, the drainage pipeline 1 is communicated with the outside, and water in the drainage pipeline 1 can be discharged.
In this embodiment, the water using device 2 is provided with a drain pump 6, and the drain pipeline 1 is communicated with the drain pump 6. The drain pump 6 is a commonly used drain device for a water using device such as a dishwasher, and is capable of pressing a water pump in an inner cavity of the water using device 2 into the drain pipe 1 to drain a resultant water flow in the inner cavity of the water using device. However, the water droplets and water stains adhering to the surfaces such as the inner wall of the water using equipment 2 cannot be discharged, and thus the water in the water using equipment remains.
the embodiment of the utility model provides a still provide a drainage method, adopt above-mentioned drainage device, solve the problem that residual moisture can't be completely arranged in the water equipment.
In this embodiment, the drainage method further includes:
And step one, controlling the drainage pump 6 to start to drain water by the water pump. At the moment, the electromagnetic valve group is in an initial opening state, the drainage pipeline 1 is dredged, the drainage pump 6 is started, most of water in the water using equipment 2 is drained, and no jet flow in the water using equipment 2 is drained.
And step two, controlling the electromagnetic valve group to act to seal the drainage pipeline 1.
when the solenoid valve group includes first solenoid valve 4, second solenoid valve 5, and first solenoid valve 4 sets up in drainage pipe 1's one end that is close to with water installation 2, and second solenoid valve 5 sets up when keeping away from with water installation 2's one end at drainage pipe 1, control the action of solenoid valve group, include drainage pipe 1 confined step: the first solenoid valve 4 is closed and the second solenoid valve 5 is closed. The first electromagnetic valve 4 and the second electromagnetic valve 5 respectively close two ends of the drainage pipeline 1, and at the moment, a closed space is formed inside the drainage pipeline 1.
And step three, starting the vacuum pump 3 and vacuumizing the drainage pipeline 1.
and controlling a vacuum pump 3 arranged on the drainage pipeline 1 to start working, and controlling the vacuum pump 3 to stop working after the drainage pipeline 1 is pumped into a vacuum negative pressure state. At this time, the air pressure in the drainage pipeline 1 is far lower than the external atmospheric pressure and the air pressure in the water using equipment 2.
And step four, controlling the electromagnetic valve group to act to enable the drainage pipeline 1 to be communicated with the water using equipment 2, and emptying the water in the water using equipment 2 by negative pressure in the drainage pipeline 1.
when the solenoid valve group includes first solenoid valve 4, second solenoid valve 5, and first solenoid valve 4 sets up in drainage pipe 1's one end that is close to with water equipment 2, and second solenoid valve 5 sets up when keeping away from with water equipment 2's one end at drainage pipe 1, control solenoid valve group action, make drainage pipe 1 and with the step that water equipment 2 communicates include:
And step four-1, controlling the first electromagnetic valve 4 to be opened, and simultaneously keeping the second electromagnetic valve 5 closed. After first solenoid valve 4 opens, drainage pipe 1 and water equipment 2 intercommunication, atmospheric pressure in the drainage pipe 1 is far less than the atmospheric pressure in the water equipment 2, under the negative pressure effect, high-pressure air in the water equipment 2 can rush into drainage pipe 1 rapidly, forms high-speed air current, and the water stain of remaining in the water equipment 2 can be wrapped up in by the air current and hold in drainage pipe 1.
And step four-2, waiting for time T, wherein the time T is 1-2 s, sucking residual water in the water using equipment 2 into the drainage pipeline 1, and collecting the residual water in the drainage pipeline 1.
And step four-3, controlling the second electromagnetic valve 5 to be opened, and discharging the water flow in the water drainage pipeline 1. Since the air pressure in the drain pipe 1 is the same as the external atmospheric pressure, the water in the drain pipe 1 is not sucked back into the drain pipe 1.
And residual water stains are removed and peculiar smell is clear by utilizing the opening time difference of the first electromagnetic valve 4 and the second electromagnetic valve 5 and synchronously utilizing the vacuum negative pressure principle.
The embodiment of the utility model provides a pair of dish washer adopts the utility model discloses a drainage device, for the direct mode of draining away of traditional dish washer drain pump, increase the residual water that the vacuum pump can't drain away the drain pump completely at whole water drainage pipeline and carry out the evacuation to the residual water of solving dish washer leads to the inside smelly peculiar smell scheduling problem that gives out of dish washer.
It is readily understood by a person skilled in the art that the advantageous ways described above can be freely combined, superimposed without conflict.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention. The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
