Abstract

The utility model discloses a travelling ice-box, being composed of two parts of a refrigerating element (1) and a box body (2). The refrigerating element (1) which is a eutectic liquid regenerator is arranged in the box body (2), and an article which requires cold preservation can be arranged in a cold preserving inner container (4); the box body (2) is composed of a housing (3), the cold preserving inner container (4), a handle (5), a box lock (6), etc., wherein, the housing (3) is composed of a hard housing upper cover (7) and a hard housing lower box (8); the cold preserving inner container (4) is composed of an inner container upper cover (9) and an inner container lower box (10). The box body can be sealed by alternation or inflation. The travelling ice-box has the advantages of simple structure, low cost and portability.

Description

Travelling ice-box

The utility model relates to a kind of passive delivery Travelling ice-box, just portable refrigerator.

Existing refrigerator, great majority adopt the compression refrigeration mode, and minority adopts the chemical refrigeration mode.The refrigerator of compression refrigeration mode, as the refrigerator that generally uses in family, the hotel, because complex structure, weight is big, and reasons such as cost height are difficult to make the portable refrigerator that uses in travelling.The refrigerator of chemical refrigeration mode, as China patent CN88211597.9 " portable refrigerator ", it is that the generation endothermic chemical reaction makes temperature reduction in the refrigerator after adopting two kinds of compound, and its weak point is: often change compound, and limited by reaction condition, inconvenience is promoted the use of.

The purpose of this utility model is the Travelling ice-box that proposes a kind of passive delivery, light practicality.

The purpose of this utility model is achieved in that this Travelling ice-box is made up of cooling module and casing two parts.Casing is made up of housing and cold insulation inner bag two parts.Cooling module is put into casing.Cooling module is selected the eutectic liquid regenerator for use, and this regenerator is placed in advance that refrigerator refrigeration is indoor to be filled coldly, when need using, regenerator from the indoor taking-up of refrigerator refrigeration, is put into Travelling ice-box cold insulation inner bag dispensing cold, makes in the case article cold insulation of lowering the temperature.

The utility model has the advantages that: 1. owing to not needing power source, therefore simple in structure, low, the light practicality of cost.2. eutectic liquid regenerator wide material sources, with regenerator be placed in advance refrigerator refrigeration indoor fill cold simple and easy, easy to carry.

Accompanying drawing of the present utility model has:

Fig. 1 Travelling ice-box structural representation

Fig. 2 Travelling ice-box casing alternating expression sealed structural representation

Fig. 3 Travelling ice-box casing inflatable seal structural representation

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is the Travelling ice-box structural representation.It is made up of cooling module (1) and casing (2) two parts.Cooling module (1) is put into casing (2).Cooling module (1) is selected the eutectic liquid regenerator for use, and it is shaped as rectangle, and size is adaptive with the both sides of cold insulation inner bag (4).Two cooling modules (1) nearly weigh 500 grams.Need the article of refrigeration to put into cold insulation inner bag (4).Before using cooling module (1) is placed on that refrigerator refrigeration is indoor to be filled coldly, when needs use, cooling module (1) from the indoor taking-up of refrigerator refrigeration, put into Travelling ice-box cold insulation inner bag (4) dispensing cold, the interior article of case are lowered the temperature.Casing (2) is made up of housing (3), cold insulation inner bag (4), handle (5) and case lock parts such as (6).Housing (3) is made up of hard shell loam cake (7) and hard shell nowel (8), and cold insulation inner bag (4) is made up of inner bag loam cake (9) and inner bag nowel (10).Housing (3) adopts the hard material manufacturing, and outer surface is topped with artificial leather.Appearance and size is 30cm * 38cm * 11cm, also can make difformity, the Travelling ice-box of different volumes as required.Cold insulation inner bag (4) adopts has certain flexible soft material and compound the making of filmogen tough and tensile, that gas barrier properties is good, makes as adopting expanded polystyrene (EPS) and PVC film composite material.

Fig. 2 is a Travelling ice-box casing alternating expression sealed structural representation.This Travelling ice-box adopts two kinds of seal form of A, B.A shape is 12 sealings of alternating expression Z type sealing surface, promptly by hard shell loam cake (7) and hard shell nowel (8) sealing, inner bag loam cake (9) and inner bag nowel (10) sealing constitute 12 sealings of Z type sealing surface between them, compress by case lock (6) application of force, play sealed, thermally insulated effect.

Fig. 3 is a Travelling ice-box casing inflatable seal structural representation.B shape is the gas-flow closure formula, utilizes air bag 11 sealings, and the outside dimensions of this air bag is greater than the inside dimension of cold insulation inner bag (4), and inflation rear gasbag 11 is pressed on place, cold insulation inner bag (4) slit automatically, plays sealed, thermally insulated effect.

The operating process of this Travelling ice-box is as follows: earlier with cooling module (1), promptly two eutectic liquid regenerators put into refrigerator refrigeration indoor fill cold, when needs use Travelling ice-box, with cooling module (1) from the indoor taking-up of refrigerator refrigeration, put into the cold insulation inner bag (4) of Travelling ice-box, the article that will need simultaneously to freeze are put into cold insulation inner bag (4), hard shell loam cake (7) are covered on hard shell nowel (8) again, are compressed by case lock (6) application of force.When 25 ℃ of environment temperatures, oven temperature, is no more than 4 ℃ in 8 hours, and under 35 ℃ of conditions of environment temperature, oven temperature, is no more than 9 ℃ in 8 hours.
