Description
Technical field
The utility model is related to a kind of heating of the metal tube of heater technical field more particularly to refrigerator good airproof performance
Device.
Background technology
The evaporator of refrigerator or freezer is in refrigeration work, as soon as evaporator surface can condense a layer frost, the thick influence of frost
Defrost is come for the big Multifunctional electric heating tube of the evaporator of the big commercial refrigerator of refrigerating capacity or freezer to evaporation endothermic.Due to evaporation
The use environment of device is more severe, and atmospheric water content is larger, belongs to clammy air, thus when electric heating tube uses be easy by
Tide easily occurs leaky, is further improved to influence heating tube insulation effect.
Utility model content
In order to solve technical problem present in background technology, the utility model proposes a kind of refrigerator good airproof performances
Metal tube heaters, effect are good.
A kind of metal tube heaters of refrigerator good airproof performance, including metal tube, conducting wire, sealing element, terminal, seal pipe,
The middle part of conducting wire is located at the inside of metal tube, and the both ends of conducting wire are located at the outside of metal tube, between conducting wire and the both ends of metal tube
It is sealed by sealing element；It is set on terminal there are two jack, two jacks are electrically connected with the both ends of conducting wire respectively；The outer circumferential table of terminal
Face is equipped with external screw thread；Seal pipe is located at the outside of terminal, and the inner circumferential surface of seal pipe is equipped with spiral shell in the first internal thread, second
Line, the first internal thread, the second internal thread are sequentially distributed along the length direction of seal pipe, and the first internal thread is meshed with external screw thread.
Preferably, conducting wire includes glass fiber rope, the heating wire being wrapped on glass fiber rope, braiding layer, silicon rubber successively from inside to outside
Glue-line, insulating layer.
Preferably, the one end of seal pipe far from terminal is equipped with elastic ring.
Preferably, metal tube has deformation area, and the metal tube for being located at deformation area is arranged in " S " type.
Preferably, it is arranged in the shape of a spiral positioned at the conducting wire in deformation area.
Preferably, sealing element is made of silastic material.
In the utility model, fever is realized by conducting wire is after jack is electrically connected with external component.Pass through rotatory sealing
Pipe, allows the second internal thread to be threadedly coupled with external component, and then realizes sealing, effectively avoids leaking electricity, can adapt to refrigerator makes
With.
By allowing sealing element sealed guide and metal tube both ends, effectively allow between conducting wire and metal tube form one it is whole
Body plays very to being entered inside heating tube in heater wet environment as refrigerator defrost in use, completely cutting off aqueous vapor
Good insulation protection, prevent moisture in moist environment and air as metal pipe mouth enter and caused by insulate and decline, avoid
The safety accident caused by electric leakage.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the amplified sectional view of terminal, seal pipe etc..
Specific implementation mode
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutual combination；Below with reference to the accompanying drawings it and in conjunction with the embodiments elaborates to the utility model.
Referring to Fig.1,2：
The utility model proposes a kind of refrigerator good airproof performance metal tube heaters, including it is metal tube 1, conducting wire 2, close
Sealing 3, terminal 4, seal pipe 5, the middle part of conducting wire 2 are located at the inside of metal tube 1, and the both ends of conducting wire 2 are located at the outer of metal tube 1
Side is sealed between conducting wire 2 and the both ends of metal tube 1 by sealing element 3；Set on terminal 4 there are two jack 6, two jacks 6 respectively with
The both ends of conducting wire 2 are electrically connected；The outer peripheral surface of terminal 4 is equipped with external screw thread；Seal pipe 5 is located at the outside of terminal 4, seal pipe
5 inner circumferential surface is equipped with the first internal thread, the second internal thread, and the first internal thread, the second internal thread are along the length side of seal pipe 5
To being sequentially distributed, the first internal thread is meshed with external screw thread.
Fever is realized by conducting wire 2 is after jack 6 is electrically connected with external component.By rotatory sealing pipe 5, allow in second
Screw thread is threadedly coupled with external component, and then realizes sealing, effectively avoids leaking electricity, and can adapt to refrigerator use.
By allowing 3 sealed guide 2 of sealing element and 1 both ends of metal tube, effectively allows between conducting wire 2 and metal tube 1 and form
One entirety rises to being entered inside heating tube in heater wet environment as refrigerator defrost in use, completely cutting off aqueous vapor
Arrived good insulation protection, prevent the moisture in moist environment and air as 1 mouthful of entrance of metal tube and caused by under insulation
Drop, avoids the safety accident caused by electric leakage.
In further embodiment, conducting wire 2 includes glass fiber rope, the fever being wrapped on glass fiber rope successively from inside to outside
Silk, braiding layer, silastic-layer, insulating layer.Make insulating layer is not direct to be contacted with heating wire, operating temperature obtains prodigious change
It is kind, the drop of heating temperature and surface temperature is reduced, refrigerator defrost effect is improved, improves service efficiency.
In further embodiment, the one end of seal pipe 5 far from terminal 4 is equipped with elastic ring 7.Convenient for close with extraneous component
