Description

Multifunctional semiconductor type refrigerator

The utility model relates to a kind of refrigerator, and particularly a kind of have fresh-keeping, refrigeration and a freezing function, with the refrigerator of semiconductor chilling plate refrigeration.

Present refrigerator is with compressor cooling mostly, because the complex structure of this refrigerator not only keeps in repair, carries inconvenience, and manufacturing cost height, power consumption height.Studies show that in recent years particularly: the fluoride in its compressor refrigerant is to constitute one of main harm of destroying atmosphere foul smell layer.

In order to solve some deficiency of compressor formula refrigerator, a kind of refrigerator that uses semiconductor chilling plate is also arranged now, this refrigerator is to utilize the semiconductor chilling plate of being close to the refrigerator inwall to come the interior heat of adsorption box, by fin and the fan of being close to cooling piece heat is spread out of outside the case again then.But at present not only volume is little, model is single for this refrigerator produced of China, and all belongs to specificity, is fit to family and uses.

In addition, though existing refrigerator has cold storage function, because of its to storage vegetables of a specified duration slightly, fruit dehydration, it is fresh and influence.Although occurred utilizing ozone and anion to dish preservation technique really in recent years in succession, the fresh-keeping problem of storage of a specified duration of the present still unresolved meat fish food of this technology.

The purpose of this utility model provides a kind of multifunctional semiconductor formula refrigerator, and it can not only fresh-keeping, refrigeration and freezing, has the effect of removing peculiar smell and sterilization in the case simultaneously again.

The purpose of this utility model is achieved in that this refrigerator is made up of the refrigeration of static antistaling box and semiconductor-type, household freezer, in antistaling box, refrigerating box, be equipped with the discharge plate of electrostatic generator, and each case all (or) be provided with independently freeze power switch and discharge plate power switch.

The utility model is because adopt semiconductor refrigerated and fresh-keeping with ozone and anion that electrostatic generator produced, not only the refrigerator of ratio piston compressor refrigeration is simple in structure, cost is low, and noiselessness, nuisanceless, and increased fresh-keeping function to vegetable and fruit, because in refrigeration, be provided with discharge plate in the household freezer and each circuit power all is provided with gauge tap, can not only remove peculiar smell in the case, and can also play sterilization functions, simultaneously can enable certain case work according to actual needs again, thereby reach the purpose of power saving.

Reach example below with reference to the accompanying drawings and be described in detail concrete structure of the present utility model and operation principle.

Fig. 1 is the front schematic view according to the multifunctional semiconductor formula refrigerator that the utility model proposes.

Fig. 2 is the side schematic view of Fig. 1.

Fig. 3 is power supply the principle figure of the present utility model.

Fig. 4 is the circuit theory diagrams of electrostatic generator of the present utility model.

Fig. 5 is the circuit theory diagrams of time controller.

As shown in Figure 1, 2: this refrigerator is to be made of four casings of three parts, I is two antistaling boxes that structure is identical, its framework 1 is to be made by aluminium or other metal mold materials, the chamber door 2 of antistaling box I and other three sides all are to be made by glass, and chamber door 2 is provided with handle 3, is provided with the static pole plate 4 of electrostatic generator in the case.The refrigerating box II of this refrigerator and the structure of household freezer III are basic identical, all be with the cooling piece of same model refrigeration, for no other reason than that the design difference of case internal volume and cryogenic temperature difference, so when the structure of narration household freezer III, also comprise the refrigerating box II.The casing of household freezer III is to be made of chamber door 5 and shell 6, and its inwall 7 is to make with aluminium sheet.Between the shell 6 and inwall 7 of household freezer III one side, be provided with a cover refrigeration mechanism, this mechanism is made up of cooling piece 8, fin 9, motor 10 and paddle-wheel fan 11, and wherein cooling piece 8 is to be close to inwall 7 with conductive liquid, and fin 9 is close to cooling piece 8.Motor 10 and fan 11 be positioned at cooling piece 8 above, and fan 11 faces the airslide of fin 9.Between shell 6 and inwall 7, be provided with polyurethane thermal insulation layer 12 in addition.

Further specify the operation principle of refrigeration mechanism below in conjunction with Fig. 1,2: after the household freezer III is connected power supply, through power rectifier the 12V direct current is defeated by semiconductor chilling plate 8, and the heat in the case is conducted to cooling piece 8 by inwall 7 and conductive liquid, the cooling piece 8 of absorption heat is again with heat transferred fin 9, meanwhile, motor 10 also drives fan 11 high speed rotating, and the air-flow that inlet scoop 14 and exhaust outlet 15 are produced is taken heat out of through fin 9.As seen from Figure 1: the discharge plate (A) 4, the discharge plate that are equipped with electrostatic generator in antistaling box I, refrigerating box II and the household freezer III are all controlled by electrostatic generator, and the power switch of each discharge electrode 4 all is independently.The power rectifier system and the temperature controller of electrostatic generator and refrigeration, household freezer all are located in the block 13.

As seen from Figure 3: the electric power system of this refrigerator is mainly divided three parts: 1. by power switch K ₁The freezing rectifier power source of controlling makes the work of household freezer III with the direct current after the rectification, 2. by K ₂The electrostatic generator system of control.The discharge plate A of electrostatic generator introduces respectively in four casings, and each discharge plate all is provided with an operating switch, 3. by K ₃The refrigeration rectifier power source of control is the same with freezing principle.In addition, also be provided with temperature controller in refrigerating box II and the household freezer III,, do not add at this to be described in detail owing to it is a prior art.
