Description
Technical field
This utility model relates to field of household appliances, particularly relates to a kind of frostless household refrigerator-freezer.
Background technology
Along with the raising of people's living standard, refrigerator has become the necessary article of ordinary people household, and refrigerator can provide low temperature environment, extends the storage life of food.But meanwhile, freezer compartment of refrigerator in use, can produce substantial amounts of frosting, causing refrigerating efficiency to be deteriorated, energy consumption is higher, thereby increases and it is possible to cause componental movement mechanism malfunctioning, must manually defrost after power-off, not only can affect the refrigerating efficiency of refrigerator, and use the most inconvenient.
Summary of the invention
In order to overcome, prior art exists above-mentioned deficiency, this utility model provide a kind of simple and compact for structure, easy to use, can regularly carry out the frostless household refrigerator-freezer of defrost process.
nullThe technical scheme in the invention for solving the technical problem is: a kind of frostless household refrigerator-freezer，Including casing、It is located at the cold room in this casing and refrigerating chamber、The refrigerating plant in being located at this casing and described cold room and refrigerating chamber freezed、And in being located at this casing and the frosting in described refrigerating chamber is carried out the defrosting device of defrost process，Described refrigerating plant includes compressor、Condenser、Vaporizer、Capillary tube and circulating fan，Described defrosting device includes the intervalometer of the Cumulative Elapsed Time for calculating described compressor、The freezing temperature controller that temperature in described refrigerating chamber is detected、The heater that described vaporizer is heated、And the defrost temperature controller that the temperature of described vaporizer detected，Described intervalometer is provided with input pin、Defrost end pin、Outfan pin and zero line pin，Described input pin is connected with described freezing temperature controller，Described defrost end pin is connected with described heater one end by temperature fuse，The other end of described heater is connected with described defrost temperature controller，Described outfan pin is connected with described circulating fan and compressor，And described circulating fan and compressor parallel，Described zero line pin is connected with power supply N end by the motor winding of described compressor.
Further, described heater is nichrome heater, because nichrome is in high-temperature water vapor, including steam-air-CO2Mixed gas in, there is good corrosion resistance；In some High Temperature High Pressure aqueous mediums, its anticorrosion stress-resistant performance is substantially better than 18-8 rustless steel and Inconel600；At H2+H2In S medium, it also has good decay resistance；In the alkaline medium containing NaOH, its anticorrosion stress-resistant performance is better than the Langaloys such as Inconel600, so nichrome heater has efficient corrosion resistance, effectively raise the safety coefficient of refrigerator defrost heating, and low cost, can make variously-shaped, meet use demand.
Further, the motor of described circulating fan is alternating current-direct current motor with cup rotor, simple and compact for structure, energy-conservation good, efficiency is high, insertion type is installed on refrigerator freezing chamber interior.
Further, the time that sets of described intervalometer was as 8～12 hours；The design temperature of described defrost temperature controller is-4～12 DEG C；The design temperature of described temperature fuse is 72～77 DEG C；Described intervalometer idle mode after defrost set the time as 3～20 minutes, and defrost is thorough.
This utility model is in use, when intervalometer starts meter accumulation when freezing temperature controller connects input pin and the energising of zero line pin, within the intervalometer setting time, outfan pin is kept to connect circulating fan and compressor, and circulating fan and compressor holding work, the working time of compressor accumulates the setting time of intervalometer, and freezing temperature controller detects that refrigerating chamber is in freezing state, then circulating fan and compressor quit work, and heater is started working thus the frosting in refrigerating chamber is carried out defrost process.The working time of heater is controlled by defrost temperature controller, heater works after a period of time, after frost is melted completely, defrost temperature controller cuts off circuit, heater quits work, if defrost temperature controller lost efficacy, temperature is increased to certain limit, circuit is cut off by temperature fuse irreversibility, defrost temperature controller and temperature fuse are the design of double insurance silk, it is to avoid the fire causing electric spark to cause refrigeration pipe to puncture due to heater short circuit itself or loose contact and causing, and electric fuse is irrecoverable design, damage must be changed, it is to avoid risk expands.After defrost completes, intervalometer enters the idle mode after defrost, i.e. enters defrost drainage works timing.After draining completes, intervalometer is again switched on the work of outfan pin, i.e. circulating fan and compressor starts, hence into next cycle of operation.
The beneficial effects of the utility model are: timing can heat refrigerating chamber, not only can reduce the formation of frost, improve the refrigerating efficiency of refrigerator, and it is the most very convenient to defrost.
Accompanying drawing explanation
Fig. 1 is circuit diagram of the present utility model.
Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
nullWith reference to Fig. 1，A kind of frostless household refrigerator-freezer，Including casing、It is located at the cold room in this casing and refrigerating chamber、The refrigerating plant in being located at this casing and described cold room and refrigerating chamber freezed、And in being located at this casing and the frosting in described refrigerating chamber is carried out the defrosting device of defrost process，Described refrigerating plant includes compressor 1、Condenser、Vaporizer、Capillary tube and circulating fan 2，Described defrosting device includes the intervalometer 3 of the Cumulative Elapsed Time for calculating described compressor、The freezing temperature controller 4 that temperature in described refrigerating chamber is detected、The heater 5 that described vaporizer is heated、And the defrost temperature controller 6 that the temperature of described vaporizer detected，Described intervalometer is provided with input pin 7、Defrost end pin 8、Outfan pin 9 and zero line pin 10，Described input pin 7 is connected with described freezing temperature controller 4，Described defrost end pin 8 is connected with described heater 5 one end by temperature fuse 11，The other end of described heater is connected with described defrost temperature controller 6，Described outfan pin 9 is connected with described circulating fan 2 and compressor 1，And described circulating fan and compressor parallel，Described zero line pin 10 is connected with power supply N end 13 by the motor winding 12 of described compressor.
