Problems solved by technology
Once the melting adhesive 39 is melted, the heat-shrinkable sleeve 38 will change from the original bonding state to a separated state, thereby destroying the sealing state of the sleeve heater 10
And when used for a long time, the heat-shrinkable sleeve 38 will also be carbonized, thereby possibly destroying the sealing state of the sleeve heater 10

Embodiment Construction
[0014] Such as Figure 3 to Figure 6 As shown, the refrigerator provided by the present invention is provided with a door 52 that can open and close the inner space of the refrigerator body 50 . The front of the door 52 is provided with a dispenser 58 . The dispenser 58 is disposed on the outer surface 54 of the door 52 and recessed inward, which can be used to take out water and ice cubes when the door 52 is in a closed state. Outer side 54 may form the front of door 52 . An instant water heater 60 is provided inside the door 52 , that is, between the outer surface 54 and the door liner 56 forming the inner surface of the door 52 . The exterior of the instant water heater 60 is provided with a water heater casing 62 . A warm water tank 66 is installed inside the water heater casing 62 . The inside of the warm water tank 66 is formed with a certain storage space that can store water. The water supply pipe 69 and the sleeve heater 70 are arranged inside the warm water tank...

The refrigerator casing heater seal structure comprises heating section formed by filling outer pipe setting electric-heat wire with magnesium oxide, sealing flange set at the extreme of outer pipe, sealing internal outer pipe and possessing through hole that makes lead-wire pin pierce through, insulation material filled between the extreme of lead-wire pin and sealing flange, isolation cap set on the outer side of insulation material, insulation protection hood set on outer side of isolation cap, and sealing coat forming between isolation cap and insulation protection hood. The invention can keep casing heater impermeable even if it is under high temperature, so it can prevent water permeating into inside of casing heater. Moreover, due to the triple waterproof process by isolation cap, insulation protection hood and sealing coat, the invention can prevent water permeating into inside of casing heater more efficiently.
Description
technical field [0001] The invention relates to a refrigerator, in particular to a sealing structure of a sleeve heater of the refrigerator which can prevent water penetration under high temperature. Background technique [0002] In order to prevent frost from forming on the evaporator, a defrosting heater is generally provided in the refrigerator. The heater for defrosting usually adopts a sleeve heater. The structure of the casing heater is to set the heating wire in the metal casing, and to fill the insulating magnesium oxide between the metal casing and the heating wire. figure 1 It is a cross-sectional view of the longitudinal structure of a refrigerator sleeve heater in the prior art. figure 2 for figure 1 Enlarged view of the casing heater seal structure. Such as figure 1 , figure 2 As shown, the outer tube 12 of the sleeve heater 10 in the prior art is made of metal material, and a coil-shaped heating wire 14 and a lead needle 16 connected with the heating wi...
