Fig. 4 is the schematic diagram of ice maker the 4th example adorned in the refrigerator of the invention process form.
Example below in conjunction with description of drawings refrigerator of the present invention.Fig. 1 is the schematic diagram of ice maker the 1st example adorned in the refrigerator of the invention process form.In Fig. 1, the ice maker 1 in the refrigerator of packing into is made up of ice-making disc 2, water tank 3, self-priming pump 4, suction side runner pipe 5, water side runner pipe 6 and magnetic valve 7.
Ice-making disc 2 is located in the refrigerating chamber of refrigerator, is used to make the water in the dish to freeze the back ice making.The part of water tank 3, self-priming pump 4, suction side runner pipe 5, water side runner pipe 6 and magnetic valve 7 are located at and are separated in the refrigerating chamber that wall and refrigerating chamber separate.In addition, water tank 3 is isolated with the member that is arranged on suction side runner pipe 5 the place aheads by other separating layers 8, and it is detachable having only water tank 3.Therefore, when water is not enough, water tank 3 can be taken off and supplementing water.Self-priming pump 4 is that gear pump, vane pump one class are by rotating and the pump of energy self-priming at a high speed.
Suction side runner pipe 5 combines water tank 3 with the water sucking mouth 4a of self-priming pump 4, suction side runner pipe 5 has the sloping portion 5b that the horizontal component 5a that is connected with water tank 3 and the predetermined angular that tilts from horizontal component 5 (at least 15 degree) extend and be connected with the water sucking mouth 4a of self-priming pump 4 downwards.The length setting of the sloping portion 5b of suction side runner pipe 5 is to make the position of self-priming pump 4 be in the bottom of the position of water tank 3.In addition, suction side runner pipe 5 forms component 5c from the connecting portion of horizontal component 5a and sloping portion 5b branch upward, component 5c be provided with magnetic valve 7 midway as valve gear, form peristome 5d at its front end simultaneously.
Water side runner pipe 6 combines with the delivery port 4b of self-priming pump 4 and supplies water to ice-making disc 2.An end of water side runner pipe 6 is connected with the delivery port 4b of self-priming pump 4, another end then be positioned at as peristome 6c ice-making disc 2 above.Port of export runner pipe 6 has the sloping portion 6a that tilts to extend with the angle identical with the afore mentioned rules angle from the delivery port 4b of self-priming pump 4 downwards, and extends and to be taken up space in order reducing and to turn back midway and extend to the sloping portion 6b of peristome 6c with the predetermined angular inclination from sloping portion 6a.
In said structure, the supplied water automatic control of control loop (not shown) of self-priming pump 4.For example in the counting process of certain hour, just changeing driving by the water supply timer (not shown) in the water supply loop.At this moment, magnetic valve 7 cuts out automatically owing to the control of water supply control loop.Can guarantee the sealing in the suction side runner pipe 5 till the peristome 6c from suction side runner pipe 5 to water side runner pipe 6 thus.Thereby the water in the water tank 3 are because the effect of self-priming pump 4 and through inhaling on the suction side runner pipe 5, and automatically supply water to ice-making disc 2 through the peristome 6c of water side runner pipe 6.In case water supply timer counting finishes, self-priming pump 4 promptly stops, and supplies water and finishes.
Supply water after the end, because the control of water supply control loop, magnetic valve 7 is opened automatically.In case magnetic valve 7 is opened, promptly the peristome 5d from the component 5c of suction side runner pipe 5 imports extraneous air.Thereby component 5c and magnetic valve 7 and peristome 5d just form the air introduction part.Make no longer sealing in the water supply path till the peristome 6c from suction side runner pipe 5 to water side runner pipe 6 thus, remain in the interior water of water supply path when finishing and be transplanted on naturally in water tank 3 or the ice-making disc 2 because of its deadweight so supply water.
Like this, when supplying water end,,, can not be detained and cause rancid going bad because of residual water is long-time so be empty in each runner pipe 5,6 because the residual water in each runner pipe 5,6 are transplanted in water tank 3 or the ice-making disc 2 naturally.In addition, 4 of self-priming pumps are just changeing when supplying water, and gear pump do not reverse, so it adds up to the above-mentioned prior art of working time ratio to lack.Thereby can increase the water supply number of times.The operating noise duration of self-priming pump also shortens.In addition, because the air introduction part is formed at the top of suction side runner pipe 5, and self-priming pump 4 is arranged on the below of water tank 3, so above-mentioned siphonage can not take place.
Fig. 2 is the schematic diagram of ice maker the 2nd example adorned in the refrigerator of the invention process form.The identical part of structural element all and Fig. 1 is represented with same-sign.
In Fig. 2, suction side runner pipe 5 flatly is connected water tank 3 with the water sucking mouth 4a of self-priming pump 4.Water side runner pipe 6 has the horizontal component 6d that is connected with the delivery port 4b of self-priming pump 4, to take up space from the vertical component 6e of the vertical downwards bending of horizontal component 6d, in order reducing and to turn back and tilt to extend to sloping portion 6f till the ice-making disc 2 with predetermined angular from vertical component 6e, and this sloping portion 6f is provided with peristome 6g at its front end.
The connecting portion that water side runner pipe 6 has horizontal component 6d and vertical component 6e plays the component 6h that branch also extends upward, and this component 6h is provided with peristome 6I at its front end.The peristome 6I of this component 6h is arranged on and is higher than water surface highest position, flows out from peristome 6I with the water of avoiding flowing through water supply path.The vertical component 6e of water side runner pipe 6 and component 6h form same inner diameter, and be bigger than the internal diameter of other parts (being horizontal component 6d and sloping portion 6f).
In said structure, self-priming pump 4 supplies water to ice-making disc 2 by the action identical with above-mentioned the 1st example.At this moment, there is extraneous air to import and do not have sealing in the water side runner pipe 6 all the time, but do not influence of the water supply action of self-priming pump 4 to ice-making disc 2 from the peristome 6I of component 6h.In case water supply timer counting finishes, self-priming pump 4 promptly stops, and supplies water and finishes.
After supply water finishing, then (after preferably passing through the stipulated time), the self-priming pump 4 just water supply timer (not shown) in the water supply control loop is done to reverse in the counting process of certain hour.So, the water that is not transplanted in ice-making disc 2 and water tank 3, the horizontal component 6d that remains in the water side runner pipe and self-priming pump 4 and the suction side runner pipe 5 just is recycled in the water tank 3.
In addition, extraneous air imports from the peristome 6i of the component 6h of water side runner pipe 6, and the sealing in the water side runner pipe 6 is disappeared.Thereby, remain in the vertical component 6e of water side runner pipe 6 and the water among the sloping portion 6f and fall naturally and be shifted into ice-making disc 2.Above-mentioned siphonage has, owing to the internal diameter of the vertical component 6e of water side runner pipe 6 so extraneous air imports easily, can not take place greater than the internal diameter of other parts again.Though making self-priming pump 4 do reversing in this example drives, but be transplanted on ice-making disc 2 by falling naturally, so the above-mentioned prior art weak point of the total working time ratio of self-priming pump 4 owing to remain in the vertical component 6e and the water among the sloping portion 6f of water side runner pipe 6.
Like this, after water supply, the water in each runner pipe 5,6 just is shifted into water tank 3 or ice-making disc 2, so each flow duct 5,6 interior sky that become can not be detained because of residual water is long-time and cause rancid going bad.In addition, this example need not to use unnecessary parts such as magnetic valve, so can reduce cost, simultaneously can realize slimming under the situation that does not increase height, so even the space of refrigerator short transverse not quite also can pack into.
Fig. 3 is the schematic diagram of ice maker the 3rd example adorned in the refrigerator of the invention process form.The identical part of structural element all and Fig. 1 and Fig. 2 is represented with same-sign.
In Fig. 3, self-priming pump 4 with its water sucking mouth 4a and delivery port 4b perpendicular to the state configuration of the horizontal part 5e that is connected with water tank 3 in the position that is higher than water tank 3.The vertical component 5g that suction side runner pipe 5 has this horizontal component 5e, tilts the sloping portion 5f of predetermined angular (at least 15 degree) upward, vertically bends and be connected with the water sucking mouth 4a of self-priming pump 4 from sloping portion from horizontal component 5e.Horizontal component 5e and partition wall 8 are chimeric.
Water side runner pipe 6 have the vertical component 6j that is connected with the delivery port 4b of self-priming pump 4, from vertical component 6j with predetermined angular tilt downwards sloping portion 6k that predetermined angular extends, taken up space from the vertical component 6m of the vertical downwards bending of sloping portion 6k, in order to reduce and the sloping portion 6n that turns back and afterwards extend to ice-making disc 2 and be provided with peristome 6p at its front end from vertical component 6m with the predetermined angular inclination.
Water side runner pipe 6 also has from the connecting portion branch of sloping portion 6k and vertical component 6m and extends, is provided with at its front end the component 6q of peristome 6r upward.The component 6q of water side runner pipe 6 and peristome 6r form the air introduction part.The peristome 6r of this component 6q is configured in and is higher than water surface extreme higher position part, flows out from peristome 6r with the water of avoiding flowing through water supply path.The internal diameter of the sloping portion 6k of water side runner pipe 6 is greater than the internal diameter of other parts (being suction side runner pipe 5, vertical component 6j, vertical component 6m and sloping portion 6n, component 6q).
In said structure, self-priming pump 4 supplies water to ice-making disc 2 by the action identical with above-mentioned the 1st example and the 2nd example.At this moment, in water side runner pipe 6, there is extraneous air to import all the time from the peristome 6r of component 6q, thus sealing do not had, but do not influence of the water supply action of self-priming pump 4 to ice-making disc 2.In case water supply timer counting finishes, self-priming pump 4 promptly stops, and supplies water and finishes.
Because extraneous air imports from the peristome 6r of the component 6q of water side runner pipe 6, so no sealing in the water side runner pipe 6.Thereby after supply water finishing, the water that remains in sloping portion 6k, the vertical component 6m of water side runner pipe 6 and sloping portion 6n falls naturally and is transplanted on ice-making disc 2.Then, the extraneous air that imports from the peristome 6r of the component 6q of water side runner pipe 6 arrives the vertical component 6j of water side runner pipe 6, falls naturally and is transplanted on water tank 3 so remain in water in self-priming pump 4 and the suction side runner pipe 5.Again because above-mentioned siphonage greater than the internal diameter of other parts, so extraneous air imports easily, can not take place in the internal diameter of the sloping portion 6k of water side runner pipe 6.
After supplying water like this, the water in each runner pipe 5,6 is transplanted in water tank 3 or the ice-making disc 2 naturally, so be empty in each runner pipe 5,6, can not cause rancid rotten because of the long-time delay of residual water.In addition, self-priming pump 4 is just just changeing driving when supplying water, so it adds up to the above-mentioned prior art of working time ratio to shorten.Thereby increased the water supply number of times, and also shorten the duration of operating noise.
Example of the present invention more than has been described, but the present invention is not limited by these examples, can do all distortion and application.For example, above-mentioned example is that ice maker is packed in the refrigerator, also can be used for other equipment certainly.In addition, the restriction that the shape of suction side runner pipe 5 and water side runner pipe 6 and angle of inclination also are not subjected to Fig. 1 to arrive shape shown in Figure 3 can be done suitably change according to the position relation of ice-making disc 2, water tank 3 and self-priming pump 4.
In addition, also the 2nd example and the 3rd example combination of ice maker promptly can be adopted structure shown in Figure 4.The ice maker of the 4th example is the structure that the previous section of self-priming pump 4 adopts the 2nd example, and in the configuration of adopting the 3rd example aspect the position relation of water tank 3 and suction side runner pipe 5.At this moment, the combination between suction side runner pipe 5 and the self-priming pump 4 is to utilize the horizontal component 5h with water sucking mouth 4a horizontal integration to carry out.
Example shown in Figure 4 has the advantage that short transverse took up space not quite, needn't make simultaneously self-priming pump 4 reversings.But, as otherwise make 4 reversings of self-priming pump and the water in the suction side runner pipe 5 returned in the water tank 3, the tilt angle alpha of suction side runner pipe 5 must be set at more than at least 10～15 degree.
Again, in Fig. 1, self-priming pump 4 only is controlled to when supplying water by the water supply control loop is just changeing driving, but after also can magnetic valve 7 is opened when supplying water end, just changes once again by making self-priming pump 4, forcibly the water in the water supply path is transplanted in the ice-making disc 2.Can accelerate the recovery of residual water like this.
In addition, also can be in Fig. 4 shown in the dotted line as Fig. 2, with component downwards (or laterally) extend, form downwards or the 6s of transverse opening portion.Like this, compare to the peristome 6I, the 6r that make progress shown in Figure 4, can avoid dust etc. to enter with Fig. 2.
Refrigerator of the present invention need not maybe can reduce the return time of self-priming pump, so can increase water supply time and water supply number of times.In addition, the working time of the self-priming pump of ice maker shortens, and the duration of the operating noise that makes us uncomfortable is shortened.Have, no sealing in the water supply path is so can prevent the siphonage that self-priming pump is easy to generate when stopping again.
