Embodiment Construction

[0022] The technical solutions of the present invention will be further described below through specific embodiments.

[0023] figure 1 It is a structural schematic diagram of the temperature compensation heater for the refrigerator compartment of the first embodiment provided by the present invention. Such as figure 1 As shown, the refrigerating room temperature compensating heater used in this type of household refrigerator includes a heating wire 5 made of metal elements, an aluminum foil 3 for attaching the heating wire 5, and a power wire 6 connected to the heating wire 5 and the connecting parts Connect terminal 2 and polyethylene tube 1 by high-frequency welding. Specifically, the outer dimensions of the aluminum foil 3 are not greater than 320×70 mm, and the aluminum foil 3 attached to the heating wire 5 is provided with three vent holes with a diameter of 2 mm. figure 1 When it is attached to the refrigerating chamber as shown, the gas between the refrigerating cha...

Abstract

The invention discloses a refrigerating room temperature compensating heater used in a household refrigerator, which comprises a heating wire attached to an aluminum foil. A breathable device through which the gas in between leaks out. Specifically, the ventilation device is N ventilation holes with a diameter of L opened on the aluminum foil. When the refrigerating room temperature compensation heater is attached to the refrigerating room liner, it is convenient for the gas between the refrigerating room compensation heater and the refrigerating room liner to flow out from the vent hole. In the compensating heater for a refrigerator disclosed by the present invention, its heating power is not greater than the M value, wherein the preferred value of M is 5.2W / m, so as to ensure that the local temperature will not be too high during the compensating heating process of the heater. It is used for compensating the temperature of the refrigerating room when the household refrigerator is working at a low ambient temperature, so as to ensure that the temperature of the refrigerating room is not too low, and it can also ensure the temperature of the freezing room.

Description

technical field [0001] The invention relates to the field of refrigerators, in particular to a temperature compensation heater for a refrigerating chamber used in a household refrigerator. Background technique [0002] At present, household refrigerators used in my country must be equipped with low-temperature compensation devices, because in winter, the temperature in most parts of our country is lower than 5°C. Turn on the heater to heat up to increase the temperature. When the starting temperature is reached, the thermostat starts, the refrigerator starts to work, and the heater stops working. When the temperature in the refrigerator drops below 5°C, start the heater again, and repeat. Loop the process. [0003] However, when the refrigerator operates at a low ambient temperature, the temperature compensation heater performs temperature compensation. The temperature compensation heater contains a heating wire inside, and the meter power of the heating wire affects the tem...
