Problems solved by technology

[0002] In autumn and winter, the outdoor air is dry, and the interior of the train compartment is no exception. Most of the passengers in the sleeper compartments travel long distances and stay in the train for a long time. However, the dry compartment environment brings discomfort to many passengers and affects passengers. quality of rest
At the same time, the electric heater in the train sleeper compartment is located under the table between adjacent sleepers. Due to the blocking effect of the table on the hot air, the hot air is directly diffused to the rest area of ​​the lower berth. When the lower berth passengers rest, their heads directly touch the The hot air brought by the electric heater, the heat of the hot air causes a large amount of liquid water to evaporate, and passengers will feel dry mouth, and the resulting discomfort will affect the quality of rest
[0003] In order to avoid discomfort caused by electric heaters, many passengers switch the positions of their heads and feet during rest to keep their heads away from electric heaters, but the noisy sound in the corridors of the carriages also affects the quality of rest
At the same time, the space of the sleeper compartment of the train is small and crowded, and it is difficult to install and use large humidification facilities

Embodiment 1

[0048] combine Figure 1-6 , the train sleeper bedside humidifying device of the present invention comprises a humidifying component 4, a hot air conveying component 5, an air leading component 6, an anion generating component 7, a water treatment component 8, a water adding component 9, an activation liquid filling component 10 and waste liquid recovery Components 11, from top to bottom along the height direction of the bunk partition board 1, are the first sleeper bed 2 and the second sleeper bed 3, the humidifying component 4, the hot air transmission component 5 and the air The deriving component 6, the humidifying component 7 generates water mist, the hot air transmission component 5 transmits the hot air into the humidifying component 4 to absorb the water mist, and then the air deriving component 6 connected with the humidifying component 4 will absorb the water mist The hot air is distributed along the bed bottom of the high-rise sleeper to the head of the low-rise sle...

Embodiment 2

[0061] The sleeping berth is 1.8m long, 0.6m wide, and 0.75m high. The air temperature in the compartment is 18°C, and the relative air humidity is 30%.

[0062] 1. The size and spacing of the distribution holes on the distribution board, the wind speed and temperature of the air outlet

[0063] Consult the reference book "Thermal Environment in the Car and Human Thermal Comfort" (edited by Li Baizhan, Zheng Jie, etc.) and literature (ANSI / ASHRAE Standard 55-1992. Thermal environmental conditions for human occupancy. Atlanta: American Society of Heating Refrigerating and Air-Conditioning Engineers, 1992) and (Kaczmarczyk J, Melikov A, Fanger P O. Human response to personalized ventilation and mixing ventilation. Indoor Air, 2004, 14(8): 17-29) concluded that:

[0064] The suitable air temperature for blowing to the human head is: 23-25°C.

[0065] The suitable relative humidity of the air blowing to the head of the human body is: 40% to 70%.

Abstract

The invention discloses a method and a device for humidifying the bedside of a train sleeper. Water is atomized in the bottom space of the lower bunk of the train, and the heated hot air absorbs the water mist to obtain humidified hot air, and the humidified hot air is distributed by the bottom of each sleeper. Above the head of the sleeper passenger, humidify the environment of the train compartment; the relative humidity of the humidified hot air is 40%-70%, and the temperature of the humidified hot air is 27-28°C. The device adopts the described method for humidifying the bedside of a train sleeper to humidify the environment of the train compartment. The air from the cabin is preheated by the electric heater, the water mist generated by the ultrasonic wave meets the air with a higher temperature, the water mist accelerates the evaporation, and the water vapor and the air are mixed into moist air and sent out, avoiding the previous humidifier. Airborne water droplets. The water softening treatment and ultraviolet disinfection lamp sterilization treatment before humidification avoids the problem of white fog and bacteria carrying in the air after humidification.

Description

technical field [0001] The invention relates to the field of humidification, in particular to a method and device for humidifying the bedside of a train sleeper, which is mainly used for humidifying and increasing oxygen in the head space of passengers in the sleeper, so as to solve the problem of dry air in the rest area of ​​the train sleeper compartment and improve the rest of the passengers quality. Background technique [0002] In autumn and winter, the outdoor air is dry, and the interior of the train compartment is no exception. Most of the passengers in the sleeper compartments travel long distances and stay in the train for a long time. However, the dry compartment environment brings discomfort to many passengers and affects passengers. quality of rest. At the same time, the electric heater in the train sleeper compartment is located under the table between adjacent sleepers. Due to the blocking effect of the table on the hot air, the hot air is directly diffused t...
