Abstract

The utility model relates to an electric refrigerator. A heat storage pipe containing regenerative heat storing material is arranged in the interval of condenser coiling pipes. A condenser and the heat storage pipe are embedded in a thermal storage plate. Cooling storage pipes filled with cooling storage materiasl are arranged in the intervals between the evaporator coiling pipes. The evaporator and the cooling storage pipes are embedded in a cooling storage plate. Thus the start-up time can be reduced effectively and the cooling effect can be improved. The refrigerator can maintain a constant temperature.

Description

Refrigerator

The utility model relates to a kind of refrigerating plant of refrigerator, especially refrigerator.

Existing refrigerator, fixing condenser on its box body wall; Fixing evaporimeter in the chamber of casing.The chamber temp of refrigerator is controlled in certain scope usually, when chamber temp reaches in limited time then start, need after the start could realize refrigeration through the regular hour, but before refrigeration, temperature also can rise; Then shut down in limited time when chamber temp arrives down, shut down the back refrigeration and stop.Temperature controlling range in chamber hour, the start cooling arrives lower limit and then shuts down, very fast temperature goes back up to turn-on temperature again, once more start.So just need frequent starting shooting and shutting down, energy consumption is bigger, is unfavorable for keeping the temperature constant state of refrigerator.

The purpose of this utility model is to overcome above-mentioned defective, and a kind of minimizing start-up time is provided, and improves refrigeration, keeps the refrigerator of constant temperature.

The utility model is achieved in that on the sidewall of casing and is fixed with condenser; Be fixed with evaporimeter in the chamber of casing, fill the heat storage tube of heat-storing material in being provided with in the interval of condenser coil, condenser and heat storage tube embed in the heat storing plate, and heat storing plate is fixed on the wall box; Fill the Chu Lengguan of cool storage material in being provided with in the interval of evaporator coil, evaporimeter and Chu Lengguan embed in the storage cold drawing, and the storage cold drawing is fixed in the chamber of casing.

Condenser and heat storage tube embed half that contact area in the heat storing plate is no less than surface area separately; Evaporimeter and Chu Lengguan embed half that contact area in the storage cold drawing is no less than surface area separately.

Adopt the utility model, be connected the heat storage tube of one with condenser, fill phase change material in its pipe, its good heat conductivity, in very short time the cryogenic temperature of refrigeration system is evenly risen in the start refrigeration, shorten the start-up time of refrigeration system, reduce temperature controlled extension transformation period, reduce the temperature difference of refrigerator chamber, impelled the constant temperature of refrigerator chamber.The heat storage tube of condenser also will keep certain temperature and temperature after refrigeration compressor is shut down, and is connected the Chu Lengguan of one with evaporimeter; when shutting down, contain certain refrigerating capacity; like this, freeze also can continue after shutting down and carry out, make the temperature of refrigerator chamber keep constant.

Below in conjunction with accompanying drawing the utility model is described further.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is the B-B cutaway view of Fig. 1.

Referring to accompanying drawing, the heat storage tube 41 that fills 134a phase change material 43 in many is set in the interval of condenser coil 4 equably, condenser 4 and heat storage tube 41 embed in the heat storing plate 42, condenser 4 and heat storage tube 41 embeds half that contacts area in the heat storing plates 42 are no less than surface area separately, and heat storing plate 42 is fixed in refrigerator 1 wall box 2; The cold pipe 51 of the storage of filling 134a phase change material 53 in many is set in the interval of evaporator coil 5 equably, evaporimeter 5 and Chu Leng pipe 51 embed in the storage cold drawing 52, evaporimeter 5 and Chu Leng pipe 51 embeds half that contacts area in the storage cold drawings 52 are no less than surface area separately, and storage cold drawing 52 is fixed in the chamber 3 of casing.

When refrigerator is enabled, owing to increased heat-storing device, press freezes to the time of normal operation and has only 1/5th of general press, when the refrigeration beginning, part refrigerating capacity makes the refrigerator chamber reduce temperature, the refrigerating capacity of a part is stored in the stored substance, when press work certain hour temperature arrives thermostat temperature, in phase change material, store certain refrigerating capacity and the refrigerator chamber reaches steady temperature, press stops refrigeration, this moment is owing to there is the heat energy of uniform temperature in the condenser heat-retaining mass, and evaporimeter storage solidifiable substance stores certain refrigerating capacity, system continues the position refrigeration though press stops refrigeration, replenish refrigerator chamber dispersed heat, make refrigerator temperature constant, when the refrigerating capacity consumption of system finishes, then press begins refrigeration, this moment, certain refrigerating capacity continued to be stored in the cooling substance, because heat-storing device makes very fast refrigeration after the start, keep refrigeration to make the refrigerator chamber temp constant, the steady temperature of refrigerating chamber can remain between-18 ℃ to-19 ℃, and the temperature of refrigerating chamber can remain between 3 ℃ to 4 ℃.
