Abstract

The utility model relates to an electric refrigerator, comprising a compressor (10), a refrigerator body (20), a door body (30), etc. A filament pipe type (50) evaporator is arranged on the inner wall of a storage chamber A, and a heat-insulating interlayer (40) can divide the storage chamber into a chamber A and a chamber B which are adjacent; the inside of the chamber B is provided with a fan (60); the heat-insulating interlayer (40) is provided with two channels (41) (42) which can communicate the chamber A with the chamber B, and the air absorbing end of the fan (60) is adjacent to one of the two channels (41) (42). The utility model can quickly and uniformly carry out refrigeration.

Description

Refrigerator

The utility model relates to the refrigerator field, specifically is the improvement structure about the refrigerator refrigerating plant.

Existing air-cooled and mixed cold refrigerator, mostly adopt finned evaporator to freeze, evaporimeter is placed in the air channel in the insulating interlayer, though finned evaporator refrigerating efficiency height, the space is less in the air channel, the easy frosting of evaporator surface, need regularly defrost during normal the use, or some position placement defrost pipe in the air channel has increased production cost again in order to avoid frosting had so both strengthened power consumption; In the air channel, place a fan in addition,, need the strict sectional area that calculates the air channel this moment, can obtain suitable cold to guarantee apotheca by flowing of its control wind.

In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to design the refrigerator that a kind of apotheca can evenly freeze rapidly.

For achieving the above object, the technical solution adopted in the utility model is: a kind of refrigerator, it comprises compressor, casing, door body and attemperating unit, it is characterized in that: insulating interlayer is separated into two chambers of adjacent A, B with apotheca, wherein in the A chamber wire-and-tube evaporator is set, one fan is set in the B chamber, has two passages that A, B two Room are communicated with on the insulating interlayer, the air draught end of fan is located near one of two passages.

In technique scheme, employing wire-and-tube evaporator refrigeration, can satisfy the requirement of apotheca fully to cold, and be not prone to the serious frosting phenomenon of evaporimeter, because during the fan blowing hot and cold amount is promptly transmitted, and then reach rapidly, the even purpose of refrigeration, need in the air channel, to be provided with finned evaporator and fan in the utility model and the prior art, and need carry out strictness calculating to duct cross-section and compare, structure is obviously simplified, cost also is minimized, and refrigeration is even rapidly, and has overcome the defective of the serious frosting of evaporimeter.

Description of drawings

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

Fig. 2 is the planar structure schematic diagram of evaporimeter.

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment

As shown in Figure 1, the ordinary construction of refrigerator is same as the prior art, and promptly it comprises compressor (10), casing (20) and door body (30), and attemperating unit all belongs to prior art.

The apotheca of placing food by casing (20) and door body (30) being used to of surrounding is separated by insulating interlayer (40) and is split into two chambers of A, B, one wire-and-tube evaporator (50) wherein is set in the A chamber, the B chamber is provided with a fan (60), two passages (41) are arranged on the insulating interlayer (40), (42) A, B two Room are communicated with, the air draught end of fan (60) is located near one of two passages (41), (42).Preferable embodiment as shown in Figure 1, insulating interlayer (40) is horizontally disposed with, passage (41), (42) lay respectively near door body (30) with away from the position of door body (30), wire-and-tube evaporator (50) is flat side's a mesh-like, referring to Fig. 2, its bareing be arranged in insulating interlayer (40) below, the plate face of wire-and-tube evaporator (50) is near insulating interlayer (40) and slightly some inclination, as shown in Figure 1.The air channel (71) that fan (60) is positioned at passage (42) top and the case (70) that is provided with along the inboard inner bag place away from door body (30) of apotheca B constitutes.

When fan (60) is worked, the cold air that evaporimeter (50) makes is drawn in the air channel (71) by passage (42) and to send into the B adjacent with evaporimeter (50) indoor, the indoor air-flow of this B enters evaporimeter (50) place again by passage (41) the indoor cooling of A, hot and cold like this amount is promptly transmitted, and finishes the process of even refrigeration.

Because wire-and-tube evaporator (50) bareing is arranged in the apotheca, the rapid and exchange heat around it of its cold that makes, its refrigerating efficiency is lower than finned evaporator in addition, thereby can avoid the generation of serious frosting phenomenon.

Claims

1. refrigerator, it comprises compressor (10), casing (20) and door body (30) and attemperating unit, it is characterized in that: insulating interlayer (40) is separated into two chambers of adjacent A, B with apotheca, one wire-and-tube evaporator (50) wherein is set in the A chamber, one fan (60) is set in the B chamber, has two passages (41), (42) that A, B two Room are communicated with on the insulating interlayer (40), the air draught end of fan (60) is located near one of two passages (41), (42).

2. refrigerator according to claim 1, it is characterized in that: insulating interlayer (40) level is to setting, passage (41), (42) lay respectively near door body (30) with away from the position of door body (30), wire-and-tube evaporator (50) for the mesh-like of fan side and bareing be arranged in insulating interlayer (40) below, the air channel (71) that fan (60) is positioned at passage (42) top and the case (70) that is provided with along the inboard inner bag place away from door body (80) of apotheca B constitutes.
