Problems solved by technology

[0004] The protection modes of the refrigerator defrosting device in the above-mentioned prior art are all protection methods during the use of the refrigerator. Although serious phenomena such as fire can be avoided, it is still impossible to avoid the increase in power consumption caused by the failure of the defrosting device. , decline in cooling effect, severe frosting in the refrigerator and other consequences, it is impossible to avoid, reduce or reduce the occurrence of the above-mentioned failures

Embodiment 1

[0026] In this embodiment, within 0-5 minutes after the refrigerator is powered on, press and hold the two buttons on the display panel for more than 10 seconds to enter the defrosting program, and the heating wire circuit starts to work. Set the heating wire circuit to work within 5 minutes after power on, and press and hold the two buttons at the same time for more than 10 seconds. The advantage of this is that it can prevent users from entering the defrosting program by mistaken operation after power on.

[0027] The defrosting program runs for 60~120 seconds, observe the operation of the defrosting program, and exit the defrosting program according to the normal program, so as to prevent the abnormality caused by the excessive work of the heating wire. In this way, the progress of the defrosting program can be observed, and at the same time, abnormal conditions can be prevented from overheating of the heating wire.

[0028] Through the set mode, manually enter the defrosti...

Embodiment 2

[0031] The second embodiment is similar to the first embodiment, so only the difference between the second embodiment and the first embodiment will be described.

[0032] After the refrigerator is powered on, step A can also enter the defrosting program in the following way, so that the heating wire circuit starts to work: After the refrigerator is powered on for 0 to 5 minutes, press and hold the specific button set on the display panel for more than a specific time, The heating wire starts to work. Entering the defrosting program in this way can also prevent the user from entering the defrosting program by mistake.

[0033] In addition, by presetting corresponding fault codes for different faults in this mode, maintenance personnel can quickly check for existing faults and perform maintenance and troubleshooting.

Abstract

The invention provides a detection device of a defrosting device for a refrigerator. The detection device comprises a heating wire circuit, a defrosting temperature sensor, a temperature fuse and a defrosting control key. The detection device is characterized in that the heating wire circuit is provided with a device requiring the heating wire to separately work; and the power can be detected by using an external power detection device. Whether the defrosting device works normally can be judged by determining whether the output power is matched with the design power.

Description

technical field [0001] The invention relates to the field of defrosting, in particular to a detection device and method for a refrigerator defrosting device. Background technique [0002] In the prior art, the defrosting device of the refrigerator adopts a high-power defrosting electric heating method. Due to the high power of the defrosting heating wire, if the defrosting device of the refrigerator fails, serious consequences will occur. If the defrosting device keeps working, it will cause the temperature inside the refrigerator to rise, so it will cause the power consumption of the refrigerator under normal use conditions to increase, and if it is serious, it will cause deformation of the plastic parts of the refrigerator body and eventually cause a serious phenomenon of fire; If the defrosting device does not work, serious frosting will occur, and ice will gradually form, resulting in abnormal operation of the refrigerator, increasing the power consumption of the refrige...
