Detailed description of the invention
In order to make the object, technical solutions and advantages of the present invention clearer, describe the present invention with specific embodiment below in conjunction with the accompanying drawings.
Referring to Fig. 1 and combine shown in Fig. 2, first embodiment of the invention has the refrigerator of frost-removal structure and includes inner container of icebox 10, the evaporator pipeline 20 being wrapped on described inner container of icebox 10 outer wall, the heater 30 being attached on described inner container of icebox 10 outer wall and be arranged on the temperature limiter 40 on described inner container of icebox 10 outer wall.
Referring to Fig. 1 and combine shown in Fig. 3, Fig. 4, described evaporator pipeline 20 is wrapped on described inner container of icebox 10 outer wall, has space 21 between its adjacent pipeline.Described inner container of icebox 10 is heated for realizing described inner container of icebox 10 is carried out defrost under defrost pattern by described heater 30, it includes some main parts 31 and some rides portion 32, the described portion 32 that rides is for connecting adjacent two main part 31, so that described heater 30 is S-type.Described main part 31 is positioned at described space 21, and is attached on described inner container of icebox 10 outer wall, so that described heater 30 and described evaporator pipeline 20 are distributed on described inner container of icebox 10 outer wall.Described ride on the evaporator pipeline 20 that portion 32 straddles between adjacent two main parts 31.Described main part 31, ride portion 32 and include the heater strip 33 for described inner container of icebox 10 is heated and for described heater strip 33 being fixed on the aluminium foil 34 on described inner container of icebox 10 outer wall or on evaporator pipeline 20.Referring to shown in Fig. 2, described temperature limiter 40 is arranged on described inner container of icebox 10 outer wall, and is electrically connected with described heater 30, is used for detecting the temperature of described inner container of icebox 10.In the present embodiment, described temperature limiter 40 is arranged on described inner container of icebox 10 outer wall, but in other embodiments, described temperature limiter 40 can also be arranged on described inner container of icebox 10 inwall.
When the described refrigerator accumulated running time with frost-removal structure reaches the first predetermined value, or when the compressor accumulated running time of the described refrigerator with frost-removal structure reaches the second predetermined value, described in there is the refrigerator of frost-removal structure will enter defrost pattern.In the present embodiment, the described refrigerator with frost-removal structure is to judge whether the accumulated running time according to refrigerator or compressor to enter defrost pattern, but the refrigerator described in actual applications, with frost-removal structure can also be forced into defrost pattern as desired by Non-follow control.When the described refrigerator with frost-removal structure is in defrost pattern, described in there is frost-removal structure the compressor of refrigerator be in the state of quitting work, described heater 30 will work and heat described inner container of icebox 10.When the temperature that described temperature limiter 40 detects described inner container of icebox 10 reaches predetermined temperature, described temperature limiter 40 will control described heater 30 and quit work.Owing to the main part 31 of described heater 30 is directly against being attached on described inner container of icebox 10, so that during the defrost of described inner container of icebox 10, described heater 30 need not be conducted heat by described evaporator pipeline 20, but directly transfer heat to described inner container of icebox 10, and then the effects such as heat transfer fast, defrost efficiency height, uniform heat distribution are reached.In the present embodiment, the described refrigerator with frost-removal structure is that the temperature according to inner container of icebox 10 judges whether to exit defrost pattern, but the refrigerator described in a particular application, with frost-removal structure can also be as desired by Non-follow control compulsory withdrawal defrost pattern.
Fig. 5 show the second embodiment that the present invention has the refrigerator of frost-removal structure.Second embodiment is substantially the same with first embodiment, the heater 50 that difference is in the second embodiment is arranged in described space 21, and be spirally wrapped around on described inner container of icebox 10 outer wall, it may be assumed that the canoe of described heater 50 is identical with the canoe of described evaporator pipeline 20.
Present invention further teaches a kind of defrosting method, comprise the steps:
S1: enter defrost pattern；
S2: described inner container of icebox 10 is heated by described heater 30；
S3: described temperature limiter 40 detects the temperature of described inner container of icebox 10；
S4: judge whether that temperature of 10 in described refrigerator reaches predetermined temperature, if having reached predetermined temperature, the most described heater 30 stops heating and exits defrost pattern, and the most described heater 30 continues heating.
Preferably, described step S1 also comprises the steps:
S11: described temperature limiter 40 detects the temperature of described inner container of icebox 10；
S12: judge whether the temperature of described inner container of icebox 10 reaches defrost temperature, if having reached defrost temperature, then enter step S14, otherwise described in have frost-removal structure refrigerator continue refrigeration；
S13: whether the accumulated running time of the refrigerator or compressor described in judgement with frost-removal structure reaches predetermined value, if having reached predetermined value, then enters step S14, otherwise enters step S11；
S14: enter defrost pattern.
Compared to prior art, the present invention has the refrigerator of frost-removal structure owing to described heater 30,50 is directly against being attached on described inner container of icebox 10 outer wall, so that during defrost, the heat that described heater 30,50 produces can be directly passed to described inner container of icebox 10, and then achieves the purposes such as heat transfer speed is fast, defrost efficiency is high.Attaching additionally, due to described heater 30,50 and described inner container of icebox 10 outer wall are gaplesss, therefore during refrigerator foaming, foamed material cannot wash described heater 30,50 open, thus substantially increases the qualification rate of product.Finally, owing to described heater 30,50 is directly against being attached on described inner container of icebox 10 outer wall, fill so that achieve gapless foamed material between foamed material and described evaporator pipeline 20, described inner container of icebox 10 and described heater 30, so that inner container of icebox 10 bubble-free, nothing after Fa Pao are layered, and then make the energy-conservation of refrigerator high insulating effect, beneficially refrigerator.
Of particular note, for the person of ordinary skill of the art, the equivalence change for the present invention made under the teachings of the present invention, must be included in the scope that scope of the present invention patent is advocated.
