Abstract

The invention discloses a heat exchange device. The heat exchange device comprises a draught fan and a detection device body. The detection device body comprises two signal elements used cooperatively with each other. Signal emission and induction are conducted between the two signal elements. One signal element is arranged on one draught fan blade and rotates along with the draught fan, and the relative position between the other signal element and the signal element arranged on the draught fan blade is constantly changed. Or, the two signal elements are oppositely arranged on the two sides of the draught fan blades. The invention further provides a draught fan fault detection method and device. According to the heat exchange device and the draught fan fault detection method and device, the problem that fault detection cannot be conducted on the draught fan when a draught fan electrical system is broken down is solved.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a heat exchange device, a fan fault detection method and a device. Background technique [0002] With the continuous improvement of people's pursuit of quality of life, the popularity and intelligence of home appliances are getting higher and higher. For example, heat exchange devices such as refrigerators and air conditioners have become necessary household appliances. Fans are generally used in these heat exchange devices, and fans play a vital role in cooling the heat exchange devices. [0003] For example, refrigerators, there are many types of refrigerators, such as air-cooled refrigerators, direct-cooled refrigerators, etc. Compared with direct-cooled refrigerators, air-cooled refrigerators use evaporators, fans, electric dampers, air ducts and other units to form a forced air circulation system. The advantages of defrosting, rapid cooling of the refrigerator, and mo...
