Description

Technical Field

[0001] The present invention relates to the technical field of EMU heaters, and specifically to a dust-proof EMU heater that is easy to clean. Background Art

[0002] During the operation of an EMU, the temperature regulation inside the car is crucial. As a key device, the heater plays an important role. By heating the air, the heater can raise the temperature inside the car and provide a comfortable riding environment for passengers.

[0003] Prior Art 1 (a Chinese patent with application number CN202411414692.4 and published on November 29, 2024) is an EMU heater with a protective structure, including a housing frame, a linkage flipping mechanism, and a dust-proof protection mechanism. The linkage flipping mechanism is arranged at the left end of the heater body and is used for the automatic flipping and unfolding or flipping and folding operations of the heater body. After unfolding, it is in an open state to assist in the convenient cleaning operation of the heater body. The dust-proof protection mechanism is arranged in a clamped state in the window of the housing frame and is used for the dust-proof protection treatment of the heater body, and is disassembled conveniently in a detachable manner to assist in the cleaning and replacement operations. This EMU heater with a protective structure meets the usage requirements of dust-proof protection for the heater, avoids the problem of poor heating effect caused by dust pollutants accumulating on the heater, and in addition, with the setting of unfolding to assist in an open state, it is easy to use cleaning tools to clean the heater, ensuring the comprehensiveness of cleaning. Prior Art 2 (a Chinese patent with application number CN202223111409.X and published on March 17, 2023) is an EMU heater with a dust-proof function, which relates to the technical field of EMU heaters, including a pipeline main body. A dust collection frame is semi-encased at the bottom of the pipeline main body. A first dust-proof filter screen is fixedly connected to one inner wall of the pipeline main body. A heater assembly is arranged inside the pipeline main body, and a dust-proof component is arranged on one side of the heater assembly inside the pipeline main body. The heater assembly includes a machine frame, a blower fan, a first installation frame, a vertical heating pipe, a second installation frame, and a horizontal heating pipe. The dust-proof component includes a conical ventilation plate and a second dust-proof filter screen. This EMU heater with a dust-proof function can improve the heat output effect of the heater through the arranged heater assembly and dust-proof component, effectively ensure the air circulation and heating inside the EMU, and has a good dust-proof effect. Dust can be centrally collected, avoiding dust from affecting the normal use of the heater and improving the service life of the heater.

[0004] The current heater heats by blowing hot air, and at the same time, air is inhaled during the blowing process. To prevent the heater from being contaminated by dust, a dust-proof structure needs to be set up. However, as the usage time of the heater increases, the dust accumulation gradually increases, affecting the subsequent air output and heating efficiency of the heater. For some heaters that can clean dust, although the dust after cleaning falls from the dust-proof structure, the dust will still enter the carriage in a closed environment, causing pollution to the carriage environment. The traditional method of cleaning dust is relatively cumbersome, reducing the maintenance convenience of the equipment. Summary of the Invention
