Description

The transfiguration refrigerator

The utility model relates to a kind of refrigerator, particularly a kind of transfiguration refrigerator.

Traditional refrigerator has the refrigerating chamber and the refrigerating chamber of fixed volume, in case after refrigerator created, the volumetric ratio of its refrigerating chamber and refrigerating chamber had also just been decided so.In existing Direct cold refrigerator, refrigerating box wherein is respectively to be determined with freezer evaporator area and relevant refrigeration piping by corresponding refrigerator evaporator with the temperature of household freezer.

At present, the evaporimeter of direct cooling refrigerator mainly contains following several form: tube-in-sheet evaporator, wire-and-tube evaporator etc.But because difference southern and northern and each family life custom; Some specific occasion is in the time of (as doing weddings and funerals in the family or having come the friends and family) simultaneously, and the user has different requirements to the refrigerating chamber of refrigerator with the refrigerating chamber volumetric ratio.

The purpose of this utility model is to provide a kind of space of setting up an independent volume in refrigerator, and can be adjusted into the transfiguration refrigerator of refrigerating chamber or refrigerating chamber at any time.

The purpose of this utility model can reach by following measure: the utility model is included in refrigerating chamber, refrigerating chamber, compressor, condenser and dew removing tube, device for drying and filtering, capillary, freezer evaporator, magnetic valve, connector, refrigerator evaporator, liquid reservoir, the muffler that is provided with in the casing, it is characterized in that: in casing, also be provided with temperature-changing chamber, be provided with temperature-changing chamber refrigeration evaporator and temperature-changing chamber refrigerating evaporator in the temperature-changing chamber.

The purpose of this utility model can also reach by following measure: temperature-changing chamber can be positioned at the middle part of casing, and the temperature-changing chamber refrigerating evaporator is divided into two parts, is located at the bottom and the top of temperature-changing chamber respectively, and the temperature-changing chamber refrigeration evaporator is located at the rear portion of temperature-changing chamber.The temperature-changing chamber refrigeration evaporator is connected between freezer evaporator and the magnetic valve, and the output that electricity produces valve is leaded up to branched pipe, two-part temperature-changing chamber refrigerating evaporator and linked to each other with tube connector, and another road is passed through branched pipe and directly linked to each other with tube connector.The bottom of temperature-changing chamber is provided with defrost water tapping equipment.Defrost water tapping equipment can be by the water draining beak of being located at temperature-changing chamber bottom, and the drainpipe that is loaded on the water draining beak is formed.Defrost water tapping equipment also can be made of the temperature-changing chamber inner chamber and the drainage switch of band water storage tank.

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

With reference to Fig. 1～Fig. 3, be divided into refrigerating chamber 1, temperature-changing chamber 2, refrigerating chamber 3 three parts in the refrigeratory body of the present utility model; Temperature-changing chamber 2 can be located at middle part (upper and lower position of three chambers can exchange); The temperature-changing chamber evaporimeter can be realized by the area that changes existing evaporimeter, be divided into temperature-changing chamber refrigeration evaporator 14 and temperature-changing chamber refrigerating evaporator 15; Wherein temperature-changing chamber freezing and evaporating 15 is divided into two parts, is located at the bottom surface and the end face of temperature-changing chamber 2 respectively; Temperature-changing chamber refrigerator evaporator 14 is located at the back of temperature-changing chamber 2.Do the time spent when temperature-changing chamber plays little freezing, 15 one of them work of temperature-changing chamber refrigerating evaporator get final product.

As shown in Figure 4,4 is that compressor, 5 is that condenser and dew removing tube, 6 are that device for drying and filtering, 7 is that capillary, 8 is that freezer evaporator, 9 is that magnetic valve, 10 is that tube connector, 11 is that refrigerator evaporator, 12 is that liquid reservoir, 13 is that muffler, 14 is that temperature-changing chamber refrigeration evaporator, 15 is that temperature-changing chamber refrigerating evaporator, 16,17 is a branched pipe.

Refrigerant circulation line is:

When making branched pipe 17 conductings (this moment, branched pipe 16 was disconnected) by electric switch 22 (or computer) control magnetic valve 9, have only 14 work of temperature-changing chamber refrigeration evaporator in the temperature-changing chamber evaporimeter, can make the temperature of temperature-changing chamber 2 reach the refrigerated storage temperature that meets national standard after the well-designed good evaporation tube separate refrigeration, thereby make temperature-changing chamber 2 become a refrigerating chamber.

When making branched pipe 16 conductings (this moment, branched pipe 17 was disconnected) by electric switch 22 (or computer) control magnetic valve 9, temperature-changing chamber refrigeration evaporator 14 and temperature-changing chamber refrigerating evaporator 15 are ganged up and are worked simultaneously in the temperature-changing chamber evaporimeter, the pipe range of this two parts evaporimeter is through appropriate design, after feasible refrigeration through certain hour reaches and stablizes, the temperature of this temperature-changing chamber can reach and meet or near the cryogenic temperature of national standard, thereby makes temperature-changing chamber play the effect of refrigerating chamber.If pipe range process appropriate design with two parts evaporimeter, after feasible refrigeration through certain hour reaches and stablizes, the temperature of this temperature-changing chamber can reach 0 ℃-5 ℃ temperature (promptly so-called little temperature of freezing), and the refrigerating chamber of this moment can satisfy the function that short-term is preserved (about, two day) or the meat food that thaws.

With reference to Fig. 5, Fig. 6,, will solve the problem of a defrost water discharging when temperature-changing chamber work is refrigerating chamber when using.As shown in the figure, can a water draining beak 18 be installed in the bottom of temperature-changing chamber 2, and then drainpipe 19 is attached thereto, so just defrost water can be emitted.

With reference to Fig. 7, Fig. 8, be alternative defrost water tapping equipment, drainage switch 21 usefulness flexible PVCs or elastomeric material are made.The drainage switch 21 of good seal is in folded state at ordinary times, and when needing discharging defrost water, the user can rotate this switch top around direction as shown, after the flattening, the defrost water in the temperature-changing chamber inner cavity water accumulation groove 20 can be thrown in the container.

The utility model has following advantage compared to existing technology: changed traditional direct-cooled electricity ice Only have the shortcoming of refrigerating chamber and the refrigerating chamber of fixed volume in the case, and utilize existing direct-cooled electricity The structural principle of evaporator of refrigerator improves the evaporimeter of design temperature-changing chamber, so that have in the refrigerator The space of an independent volume can be adjusted into refrigerating chamber or refrigerating chamber at any time, has widened direct-cooled The development and application field of refrigerator.
