Description

Technical Field

[0001] The utility model relates to the technical field of cleaning robots, in particular to a cleaning robot with an anti-icing function. Background Art

[0002] When the ambient temperature drops below zero, the maintenance of the cleaning robot faces a severe challenge - the problem of icing. In such a low-temperature environment, the key working parts of the robot, such as the water tank, water pipes and cleaning brushes, are very likely to form ice layers due to condensation of water. This phenomenon has a significant impact on the performance and function of the robot. Slight icing may only lead to a decrease in cleaning efficiency, making the cleaning operation that should have been quick and thorough become slow and not thorough enough. This not only prolongs the cleaning time, but may also leave stains due to incomplete cleaning, reducing the cleaning quality. However, what is more serious is that when the icing situation is serious to a certain extent, these ice layers will seriously hinder the normal operation of the robot, and even cause it to fail to start normally. Therefore, in order to ensure the normal operation of the cleaning robot in a low-temperature environment, technicians in this field urgently need to develop a cleaning robot with anti-icing function.

[0003] A Chinese patent (publication number: CN218622040U) discloses a sweeper; the patent includes a frame, a trash can and a cleaning device all arranged on the frame, and the trash can is located at the bottom of the frame; the drying device includes a heating mechanism, a fan and an air duct, the heating mechanism is connected to the fan, the air duct is connected to the heating mechanism, and the air outlet of the air duct is located in the center of the frame; when the frame passes through the sprayed working surface, the heating mechanism generates heat energy, the fan blows the heat energy into the air duct to form hot air, and blows the hot air out to quickly dry the cleaned working surface to avoid water stains that make the working surface slippery; in actual use, it was found that the patent can only dry the working surface, and when the ambient temperature is low, the cleaning brush will freeze, resulting in ineffective cleaning.
