Description

Water dispenser
Technical field
The present invention relates to be used to distribute the water distribution units of drinking water, and relate to the water distribution units that places bench-top especially with refrigeration and filtering function.
Background technology
The drinking water source that water distribution units is used to provide convenience and can being equipped with is used for the water filter of filtered water before distributing.In such water distribution units, the user water is enclosed in that the top is provided with and with hopper that ceramic water filter fluid is communicated with in.Water relies on gravity by water filter, and the water that filters is kept at the water tank that is used for by the nozzle dispensing water.The shortcoming of such water distribution units is that this filter process is slow, and therefore at any time the amount of assignable filtered water be subjected to the restriction of water tank capacity.Thereby another shortcoming of this water distribution units is a nozzle must be arranged on the water filtration process that the base portion of water distribution units make to rely on gravity supply with and effectively move.This setting also is not easy to fill glass and other containers, thereby holds this container because the gap must be set under nozzle.If this water distribution units setting in the plane, this is unpractical.
These problems can be by providing pump to solve between hopper and water filter, thereby force water to pass through water filter with faster rate.This makes this filter start on request, exempts the needs to water tank thus.Using the further advantage of pump is to use the activated carbon water filter to replace ceramic water filter, and it can improve filter efficiency.Further, this filtered water can offer and be positioned near the nozzle in this water distribution units top, and container can easily be contained in this nozzle below like this.
A this water distribution units comprises the removable hopper with draining valve.This draining valve is connected to the inlet of centrifugal pump through inner conduit.Successively, the outlet of pump is connected on the activated carbon water filter via conduit.By conduit water filter is connected with near the water distribution units top nozzle again.This pump and water filter are arranged on the hopper below in the water distribution units.The draining valve of hopper allows this hopper to remove from water distribution units to be used for filling with or changing water filter.This water distribution units can be filtered on request and be flowed near the nozzle that is positioned at the water distribution units top from the water of hopper and with this filtered water.Yet the major defect of this water distribution units is that air can accumulate in removable hopper and the conduit between the pump.This causes cavitation and the loss of pump pressure thereupon in the pump.Further shortcoming is in order to change water filter, thereby hopper must be removed the path that leads to water filter is provided.
The inventor has developed improved water distribution units now.

The specific embodiment
Water distribution units 10 is described in Fig. 1 and 2, and has housing 12, and this housing 12 has removable cover cap 14.As optimum illustrating in Fig. 3, this cover cap 14 provides the path that leads to hopper 16 in the housing 12.This hopper 16 has the osculum 18 that is formed in its matrix.This osculum 18 is by screen cloth 20 coverings and comprise cross rib 22.
With reference to cutaway view 3 to 5, the centrifugal pump 24 with pump chamber 26 is installed on the hopper 16, and wherein the inlet of pump 24 is installed to osculum 18 places in this hopper 16.The rotating shaft that this pump 24 is mounted to pump 24 when this water distribution units 10 is vertically placed is vertical.This pump chamber 26 is formed with upwards and is inside towards the tapered taper end face of the inlet of this pump 24.
Activated carbon water filter 28 is externally mounted on the water distribution units 10 at this housing 12, and cooler bin 30 is installed in housing 12 inside.Thermostat 32 and thermoelectric (al) cooler (peltier effect device) 34 is installed in the cooler bin 30.
Nozzle 36 is arranged near the top of water distribution units 10 of chamber wall recessed (recess) 38 tops.Braking plate 40 is installed in the chamber wall recessed 38 with the back below nozzle 36.Braking plate 40 is equipped with the LED-backlit silicon liner 42 that embeds in the braking plate 40.
Conduit 44 connects: (i) inlet of the outlet of pump 24 and water filter 28, the (ii) inlet of the outlet of water filter 28 and cooler bin 30, the (iii) outlet of cooler bin 30 and nozzle 36 and (iv) walk around this cooler bin 30 connect the outlet and the nozzle 36 of water filter 28.As optimum illustrating in Fig. 4, first magnetic valve 48 is arranged in the conduit 44 between cooler bin 30 and the nozzle 36.Second magnetic valve 50 is arranged in the conduit 44 between water filter 28 and the nozzle 36.
Be in operation, water distribution units 10 vertically is placed on counter top or other surfaces, as shown in Figure 1.By thermostat 32 controls, the water in the cooler bin 30 keeps cooling by thermoelectric (al) cooler (peltier effect device) 34.The user can utilize the touch sensor of water distribution units 10 fronts or button to select to distribute cooling or room temperature water.Corresponding to user's selection, LED-backlit silicon spacer 42 is suitable for producing white light when selecting room temperature water, perhaps shows blue light when the water in selection cooling water and the cooler bin 30 is cooled to the temperature of 6 ℃ (+/-1 ℃).If selected cooling water, and the uncolled temperature to 6 ℃ (+/-1 ℃) of the water in the cooler bin, white light then produced.This user presses against glass or other containers on braking plate 40 then.Push this braking plate 40 and start pump 24, this pump draws water from hopper 16 successively, makes water pass through water filter 28.If this user has selected room temperature water, first magnetic valve 48 will cut out and second magnetic valve 50 will be opened, and force water to flow out to walk around cooler bin 30 and pass second magnetic valve 50 behind the water filter 28 to arrive nozzles 36.Selectively, if the user has selected cooling water, first magnetic valve 48 will be opened and second magnetic valve 50 will cut out, and enter cooler bin 30 after forcing water to flow out water filter 28, arrive nozzles 36 thereby force cooling water to discharge cooler bin 30 and pass first magnetic valve 48.
When the top is seen, the cross rib 22 similar cross-hairs in the osculum 18, its assists to prevent to form eddy current when the water of extracting out from entering the inlet of pump 18 in hopper 16 from hopper 16.Rifling is arranged on the laminar flow that is used to provide more water on the inner surface of nozzle 36, thereby and nozzle 36 tilt to assist to prevent to reflect back with about 8 ° angle.
Because the inlet of pump 24 is installed on the outlet opening 18 of hopper 16, pump chamber 26 straight-through ground are communicated with hopper 16 fluids.This guarantees that pump is always ready, and helps to prevent cavitation by the pipeline of eliminating between hopper 16 and the pump 24, because can accumulate air pocket in this pipeline.Further, because pump 24 is mounted to and makes its rotating shaft vertical, the taper end face of pump chamber 26 impels bubble upwards and inwardly to float and enter hopper 16 towards osculum 18.This helps to prevent accumulation air pocket in pump chamber 26 and causes cavitation.In addition, owing between hopper 16 and pump 18, do not need conduit and valve, so the design of this water distribution units 10 is more effective and compact.
This setting also allows water filter 28 is arranged on outside accessible position, and water filter 28 can be removed like this, is used for from the outside replacement of the housing 12 of water distribution units 10.This is convenient to change the operation of water filter 28 very much.Valve/microswitch devices can be arranged between the inlet of main pipe 44 and water filter 28, thereby prevents that water leaks from main pipe 44 when removing water filter 28.This microswitch valve gear also can be connected to the emergency warning lamp on the housing 12, thereby shows that to the user water filter 28 has been removed.
It will be understood by those skilled in the art that according to shown in the specific embodiment, can make many variations and/or modification to the present invention, these variations and/or modification do not deviate from broadly described the spirit or scope of the present invention.Therefore, present embodiment all is considered to be exemplary and not restrictive no matter from which side.
