Detailed description of the invention
In order to make the object, technical solutions and advantages of the present invention clearly, describe the present invention below in conjunction with the drawings and specific embodiments.
Refer to Fig. 1, Fig. 2 and shown in composition graphs 3, the present invention can the direct cooling refrigerator 100 of automatic defrosting comprise casing 10, be arranged in described casing 10 and be used for the refrigerating chamber 20 of foodstuff storing, refrigerating chamber 30, described refrigerating chamber 20 is carried out defrost defrosting system and match with described casing 10 and merge the door body 40 of closed described refrigerating chamber 20 and described refrigerating chamber 30.Described refrigerating chamber 20 is arranged on the below of described refrigerating chamber 30.Described door body 40 is provided with the described refrigerating chamber 20 of display and whether enters the display screen (not shown) of defrost pattern, when described can the direct cooling refrigerator 100 of automatic defrosting enter defrost pattern time, described display screen brightens, otherwise described display screen extinguishes.
Refer to shown in Fig. 1, Fig. 2 and Fig. 3, the evaporator pipeline 22 that described refrigerating chamber 20 comprises freezing inner bag 21 and is wrapped in outside described freezing inner bag 21, between two pipelines that described evaporator pipeline 22 is adjacent, there is space 221.Described defrosting system comprise be arranged on heater 23 outside described freezing inner bag 21, to be arranged on outside described freezing inner bag 21 so as to detect described freezing inner bag 21 surface temperature temperature limiter 24, remember described refrigerating chamber 20 cooling time and master control borad (not shown) that whether described heater 23 work can be controlled and control described refrigerating chamber 20 to freeze or the operating key 25 of defrost.Described heater 23 heats to realize carrying out defrost to described freezing inner bag 21 under defrost pattern to described freezing inner bag 21, it comprises some main parts 231 and somely rides portion 232, the described portion 232 that rides connects adjacent two main parts 231, to make described heater 23 S-type.Described main part 231 is positioned at described space 221, and is attached on described freezing inner bag 21 outer wall, thus described heater 23 and described evaporator pipeline 22 are distributed on described freezing inner bag 21 outer wall.Describedly to ride on evaporator pipeline 22 that portion 232 straddles between adjacent two main parts 231.In the present embodiment, described heater 23 is S-shaped aluminium foil heater strip, but in other embodiments, described heater 23 can also be spirally wrapped around on described freezing inner bag 21 outer wall, and is positioned at described space 221; Described heater 23 can also be film heating silk.Because described heater 23 is directly installed on described freezing inner bag 21 outer wall, thus make described heater 23 promptly can transfer heat to described freezing inner bag 21, and then make described freezing inner bag 21 defrost speed.Refer to shown in Fig. 3, described temperature limiter 24 is arranged on described freezing inner bag 21 outer wall, and is electrically connected with described heater 23, is used for detecting the temperature of described freezing inner bag 21.In the present embodiment, described temperature limiter 24 is arranged on described freezing inner bag 21 outer wall, but in other embodiments, described temperature limiter 24 can also be arranged on described freezing inner bag 21 inwall.Because described temperature limiter 24 is directly installed on described freezing inner bag 21, thus make described temperature limiter 24 can measure the temperature of described freezing inner bag 21 exactly.Whether described master control borad can remember the cooling time of described refrigerating chamber 20, and whether reach scheduled duration according to cooling time and control described heater 23 and work.After the defrost of described refrigerating chamber 20, described master control borad starts the cooling time remembering described refrigerating chamber 20; When described cooling time reaches preset duration, described refrigerating chamber 20 will enter defrost pattern, describedly can the compressor of direct cooling refrigerator 100 of automatic defrosting quit work, described heater 23 is started working, and the refrigerating chamber cooling time of described master control borad memory simultaneously resets; When described temperature limiter 24 detects that the temperature of described freezing inner bag 21 reaches predetermined temperature value, described freezing inner bag 21 exits defrost pattern, enter refrigeration mode, described can the compressor starts work of direct cooling refrigerator 100 of automatic defrosting, described heater 23 quits work, and described master control borad starts the cooling time again remembering described refrigerating chamber 20 simultaneously.Whether refer to shown in Fig. 1, described operating key 25 is arranged on the inwall of described refrigerating chamber 30, is single-pole double-throw switch (SPDT), control described heater 23 and work.When switch is positioned at defrost side, describedly the direct cooling refrigerator 100 of automatic defrosting can directly enter defrost pattern; When switch is positioned at refrigeration side, describedly the direct cooling refrigerator 100 of automatic defrosting directly can enter refrigeration mode, thus realize described can the defrost pattern of direct cooling refrigerator 100 of automatic defrosting and the active of refrigeration mode switching.In the present embodiment, described operating key 25 is arranged on the inwall of described refrigerating chamber 30, but in other embodiments, the installation site of described operating key 25 can be determined as required.In the present embodiment, described operating key 25 is single-pole double-throw switch (SPDT), but in other embodiments, described operating key 25 can also be touch key-press.When described operating key 25 is touch key-press, described operating key 25 can also integrate with described display screen.
Use the present invention can the direct cooling refrigerator 100 of automatic defrosting time, the active that user can realize defrost pattern and refrigeration mode by described operating key 25 as required switches, and also can be realized the automatic switchover of defrost pattern and refrigeration mode by described master control borad.
Compared to prior art, of the present invention can the direct cooling refrigerator 100 of automatic defrosting owing to being provided with heater 23 and master control borad, thus make described can the direct cooling refrigerator 100 of automatic defrosting can automatic defrosting, and then save manpower, bring conveniently to the use of people.
Of particular note, for the person of ordinary skill of the art, done for equivalence change of the present invention under the teachings of the present invention, must be included in the scope that the present patent application the scope of the claims advocates.
