Dew removal control method for built-in cameras of refrigerators

Abstract

The invention discloses a dew removal control method for built-in cameras of refrigerators, and relates to the technical field of dew removal for built-in cameras of refrigerators. The dew removal control method includes enabling photographing functions and acquiring camera surface temperatures Ti, camera surface humidity RHi and corresponding dew temperature Ts if doors of chambers in which the cameras are positioned are closed; carrying out dew removal control according to initial values of set compressor rotational speeds Ni and fan initial rotational speeds Nfi if an inequality of |Ti-Ts|<= 1 DEG C is met, and dynamically controlling compressor rotational speeds Ni and fan rotational speeds Nfi according to change rates of the camera surface humidity RHi; taking photos after dew is removed, and transmitting the photos to interfaces capable of being consulted by users. The dew removal control method has the advantages that temperature and humidity change values of the surfaces of the cameras are detected in real time after the photographing functions are enabled, camera surface temperature values are compared to corresponding dew temperature values at the corresponding temperatures and humidity, refrigeration compressors and fans can be timely started, different rotational speeds are controlled, accordingly, the dew on the surfaces of the cameras can be timely and effectively removed, and a clear photo can be assuredly obtained whenever the users use consulting functions.

Description

technical field [0001] The invention belongs to the technical field of dew removal of a built-in camera in a refrigerator, and in particular relates to a method for controlling dew removal of a built-in refrigerator. Background technique [0002] At present, there are more and more categories of smart refrigerators on the market, and smart applications are increasingly recognized by users. The popularity of intelligent refrigerators has brought great convenience to users. For example, the built-in camera in the refrigerator box can use the smart remote viewing control system to check the food situation in the refrigerator room anytime and anywhere through the mobile phone. How much information is left, which greatly facilitates the user, avoids the user to go home and open the refrigerator door, and checks layer by layer, saves the user's time, and brings great convenience to the user's life. [0003] However, during the actual use of the camera, the user frequently opens a...

Problems solved by technology

[0003] However, during the actual use of the camera, the user frequently opens and closes the door, changes in the ambient temperature and humidity of the outside world, and changes in the temperature and humidity of the food the user puts in, causing condensation on the camera lens. For conventional solutions, see the patent: An anti-fog control method for a camera of a refrigerator (publication number: CN106123475A), the patent is to use the heating wire near the camera to dynamically control the heating of the camera, and calculate the difference between the temperature of the camera and the environment to solve the problem of condensation on the camera

This method can only alleviate or eliminate the condensation problem from the inside, but the condensation on the outer surface of the camera placed in the box space cannot be solved well
