Problems solved by technology

[0008] That is to say, defrosting cannot be effectively carried out in the part where there is a lot of frost, and in the part where there is no frost, the heat will be conducted to the outside, resulting in high temperature inside the refrigerator.
[0009] In addition, if the heating wires are wound at the same intervals regardless of the amount of frost generated on the evaporator, the same amount of heat will be generated in each part, which will lead to unnecessary waste of electric energy and cause the above-mentioned problems.

Embodiment Construction

[0023] The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings.

[0024] image 3 It is a cross-sectional view showing that a heater is placed inside a heater tube made of an aluminum tube in the present invention. Such as image 3 As shown, the heater of the present invention includes a heating wire 56 and an insulating sheath 52 . The above-mentioned heating wire 56 is wound on the core 54; the above-mentioned insulating sheath 52 surrounds the outer part of the above-mentioned heating wire.

[0025] In addition, a non-heat generating section a is formed at both end portions of the heater. The non-heat generating section a is formed by connecting a highly conductive metal material in parallel to the outer portion of the heating wire wound around the core 54 and having a constant resistance.

[0026] In the present invention, the heating wire 56 wound on the above-mentioned core 54 is composed of portion...

Abstract

A defrosting heater assembly for refrigerator features that the heater is inserted in heater tube, the heater tube and medium tube are arranged on evaporator, and the electrothermal wire is wound on a core in such manner that the electrothermal wire relative to lower part of evaporator has higher winding density and the electrothermal wire relative to upper part of evaporator has lower winding density.

Description

technical field [0001] The present invention relates to a defrosting heater for a refrigerator with the following effects: by setting different winding amounts of heating wires along the length of the heater, the defrosting process for removing frost attached to the evaporator can be effectively performed. Background technique [0002] The cold air in the refrigerator is produced by the contact of air with the evaporator. In addition, air circulates inside the refrigerator, and moisture contained in the air adheres to the surface of the evaporator, which is relatively cold, to form frost. If the above-mentioned frost is formed as ice having a certain thickness or more, the heat exchange performance of the evaporator is hindered, so it is necessary to perform a defrosting process at a certain time period. Generally, the above-mentioned defrosting process is performed by generating heat from a heater provided on the evaporator. [0003] figure 1 Front view showing a typical...
