For solving the problems of the technologies described above, the first technical scheme of the present invention is:
The invention provides a kind of refrigerator automatic defrosting system, comprise the compressor be located in refrigerator, refrigerating evaporator, Defrost heater, timer, compressor and refrigerating evaporator are by refrigeration pipe UNICOM, Defrost heater is distributed in around refrigerating evaporator, by Timer Controlling, described refrigerating evaporator adopt outside the inner container of icebox that is wrapped in and is positioned at foaming layer around pipe evaporator, refrigerator body top be provided with flow into for defrosting water, the functional disc collected outside rear outflow casing.
Further, lowly after high before making bottom described functional disc shape is tilted backwards.
Further, described functional disc inner bottom part is provided with guiding gutter from front to back, functional disc bottom rear be provided with for defrosting water flow out outside casing osculum.
Further, described functional disc position inner container of icebox place correspondence be provided with facilitate defrost current outlet external water receiving stand.
Further, the drainpipe set by water receiving stand connect box, defrosting water flows out casing from drainpipe.
To sum up, the defrosting water at refrigerator body top flows in the functional disc at top, then flows to water receiving stand from the guiding gutter of functional disc, flows out to casing from the drainpipe be connected with water receiving stand.
Further, the inner container of icebox sidewall of described refrigerating evaporator position is provided with for defrosting water from the sidewall guiding gutter sidewall outflow casing.
Further, the lower end of described sidewall guiding gutter is provided with sidewall osculum.
To sum up, refrigerator madial wall defrosting water is flowed out to outside casing by the sidewall osculum of sidewall guiding gutter.
The present invention also provides the control method of above-mentioned refrigerator automatic defrosting system, and it comprises the steps:
Step 1: Timer Controlling compressor is accumulative moves to the stipulated time, and compressor cuts out;
Step 2: Defrost heater starts heating, defrosting starts, and refrigerator sidewall defrosting water flows out outside casing along sidewall, and top defrosting water flows out outside casing by functional disc;
Step 3: after defrosting completes, Defrost heater is closed, and timer conter resets, and refrigerator normally works.
In such scheme, described compressor and Defrost heater running time are optimized coupling according to the watt level of the volume size of refrigerator, pipe-line system, Defrost heater.
Compared with prior art, the present invention has following beneficial effect:
Refrigerating evaporator of the present invention is designed to the form around household freezer courage, guarantee that refrigerator frost layer in process of refrigerastion is attached to refrigerator inwall surrounding, the present invention increases automatic defrosting system in the system-based of direct cooling refrigerator, to reach the object of frostless or micro-frost, additionally by arranging discharge structure, reach and automatically process defrosting water, the organic assembling of automatic defrosting system and discharge structure, forming can automatic defrosting process the direct cooling refrigerator of defrosting water.

Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the present invention is described in detail.
Shown in Fig. 1 to Fig. 8, the present invention discloses a kind of refrigerator automatic defrosting system, comprise the compressor be located in refrigerator, refrigerating evaporator 1, Defrost heater, timer, these parts form the automatic defrosting system of direct cooling refrigerator, wherein refrigerating evaporator adopt outside the inner container of icebox that is wrapped in and is positioned at foaming layer around pipe evaporator, refrigerator body top is provided with and flow into top for defrosting water and flow out the functional disc 2 outside casing.The present invention and general being distinguished as of defroster system have been selected around pipe evaporator.Evaporation tube around pipe evaporator is wrapped in outside inner bag, is positioned at foaming layer.Use around pipe evaporator, in refrigerator, frosting position is dispersed in wall of inner container.Frost thickness is thin, easily through heating, melts as defrosting water.
Automatic defrosting system of the present invention realizes automatic defrosting.As Fig. 8, concrete Defrost method is: run a period of time by Timer Controlling compressor is accumulative, compressor is in closed condition, Defrost heater starts heating, and defrosting starts, after defrosting completes, Defrost heater is closed, and timer conter resets, and refrigerator normally works.Compressor and Defrost heater need be optimized coupling according to the watt level of the volume size of refrigerator, pipe-line system, Defrost heater running time.
Due to the inwall being centered around household freezer courage that refrigerating evaporator 1 is taked, refrigerator defrosting water in running is mainly present in side wall of inner and top.Therefore by arranging drain structure at inner container of icebox, refrigerator can be made automatically to process defrosting water.Concrete, as Fig. 2 to Fig. 6, top defrosting water flow in functional disc 2, functional disc 2 bottom design has guiding gutter 21, and guiding gutter 21 posteriorly tilts, and makes defrosting water be pooled to functional disc 21 rear portion, there is osculum 22 at functional disc 21 rear portion, the inner container of icebox place correspondence of osculum 22 position is provided with water receiving stand 3, and water receiving stand 3 connects drainpipe 5, and defrosting water flows out to casing from drainpipe 5.Like this, the defrosting water at refrigerator body top collects in the functional disc 2 at top, then from the guiding gutter 21 of functional disc 2, flows to water receiving stand 3, flow out to casing from drainpipe 5 by osculum 22.
Functional disc 2 can food container, also can collect the defrosting water at refrigerator top.Non-horizontal bottom functional disc 2, in inclination N ° angle bottom it, concrete angle is determined according to refrigerator size, functional disc 2 rear portion is minimum, in Fig. 3, and rear portion minimum point 23, in Fig. 6, functional disc 2 can move around in the direction of the arrow, refrigerating evaporator 1 surrounding distribution Defrost heater.
In addition, in Fig. 7, the inner container of icebox sidewall of refrigerating evaporator 1 position is provided with for defrosting water from the sidewall guiding gutter 11 sidewall outflow casing, the lower end of sidewall guiding gutter 11 is provided with sidewall osculum 4, like this, the defrosting water of inner container of icebox sidewall flows down along sidewall, collects in sidewall guiding gutter 11, flows out casing by sidewall osculum 4.
Above embodiment only for illustration of technical scheme of the present invention, is not intended to limit; Although with reference to preferred embodiment to invention has been detailed description; those of ordinary skill in the field are to be understood that; still can modify to the specific embodiment of the present invention or equivalent replacement is carried out to portion of techniques feature; and not departing from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope of request of the present invention protection.
