Embodiment Construction

[0034] The glass dew dew device of the present invention can be used for dew dew on glass doors of refrigerating and freezing equipment, for example.

[0035] Such as figure 1 A schematic diagram of a first embodiment of the glass dew removal device of the present invention is shown, including a temperature detection unit 1 , a control unit 3 and a dew dew unit 4 . in:

[0036] The dew removal unit 4 is used to remove dew on the outer layer of the glass door, and can be composed of a heating device attached to the outer layer of the glass door, such as an electric heating film, or can be formed by an air supply device whose wind direction is towards the outer layer of the glass door. Such as a fan, or an air supply device that can send hot air, such as a fan that includes a heating wire device similar to a hair dryer structure.

[0037] The temperature detection unit 1 is used to detect the temperature of the inside and outside of the glass door, which can be realized by two...

Abstract

The invention provides a device for removing dew on glass, comprising a dew removing unit, a temperature detection unit and a control unit, wherein the dew removing unit is used for removing dew on the outer surface layer of the glass; the temperature detection unit is used for detecting the temperature inside and outside the glass; and the control unit is used for confirming whether reaches a dewpoint or not according to the temperature difference detected by the temperature detection unit inside and outside the glass, controlling whether the dew removing unit is started or not and carrying out power control in the dew removing process. The invention also provides a method for removing the dew on the glass, comprising the following steps of: detecting the temperature inside and outside the glass; then confirming whether reaches the dewpoint or not according to the detected temperature inside and outside the glass; and controlling the starting and the power of dew removing on the outer surface layer of the glass. The invention can be used for solving the dew condensation trouble under different temperature differences.

Description

technical field [0001] The invention relates to a glass dew dew device and method. Background technique [0002] For refrigerators with glass doors, due to the inconsistency in temperature between the inside and outside of the glass doors of the refrigerator, when the outside reaches a certain humidity, it is easy to generate condensation on the glass surface, affecting people's sight. [0003] In order to solve the problem of glass condensation, natural or electric heating can be used to remove dew. The disadvantage of natural dew removal is that not only the dew removal time is long, but also the dew removal effect will become relatively poor in high temperature and high humidity environments. The electric heating dew removal method is divided into manual electric heating dew removal method or automatic dew removal method. The manual electric heating method needs to manually judge the condensation conditions to decide whether to turn on or off the heating device. Not onl...
