Description

Technical Field

[0001] The invention relates to the technical field of electric heaters, in particular to an assembled electric heater for a train compartment. Background Art

[0002] With the rapid development of modern transportation, passengers pay more and more attention to the comfort of the interior environment of the car. Especially when traveling long distances or driving in winter, the temperature regulation and air quality in the car have a vital impact on the comfort experience of passengers.

[0003] Traditional carriage heating systems often have some problems and are difficult to meet the diverse needs of passengers. For example, the air intake mode is relatively single during use. When air intake is required, external air can only be drawn from outside the carriage for heating. When used for a long time, the heating module will have a high energy consumption problem. In addition, because the air outlet in the carriage is generally fixed on the side wall or top of the carriage, only hot air will be generated in one direction when the air is discharged. The number of air outlets installed in the carriage is limited, and the fixed wind direction may easily lead to uneven hot and cold in different positions inside the carriage, which will affect the passengers' riding experience and cause discomfort to the passengers. It is also inconvenient in later maintenance because the air inlet is generally set on the top of the outside of the carriage, and in order to prevent debris from entering and blocking the air inlet, the air inlet generally needs to be equipped with an interception net. However, after long-term use, the interception net needs to be cleaned and replaced. At this time, the staff needs to climb to the roof to work, which makes the cleaning work inconvenient. In addition, due to the high altitude of the train, there will be certain dangers during the work process. Summary of the invention

[0047] One end of the ventilation pipe 7 is connected to the outside air to form an external air inlet 29, and the other end is connected to the interior of the car through the filter screen of the filter plate 9 to form an internal air inlet 30. The filter screen of the filter plate 9 can filter out impurities in the air. When the filter plate 9 needs to be cleaned, the engagement effect of the buckle and the buckle plate 10 can be cancelled, and the filter plate 9 can be pulled out from the bottom of the device for cleaning. The cover plate 21 is rotated inside the box body 1 through the shaft and the gear disc 36. When the cover plate 21 is rotated to a certain angle, the source of the air inlet can be switched, that is, choosing to intake air from the outside or from the inside.

[0048] The heating mechanism also includes: a temperature detector 19, which is located inside the box 1. A heating tube 15 is also provided inside the box 1. The heating tube 15 is located below the air outlet of the exhaust fan 16. The temperature detector 19 and the heating tube 15 are connected via a transmission cable 17. The temperature detector 19 is used to detect the temperature of the drawn air and transmit the signal to the heating tube 15 via the transmission cable 17 to limit the heating power of the heating tube 15.

[0049] Through the rotation of the exhaust fan 16, air is sucked in from the air intake mechanism and sent to the heating pipe 15 through the air supply pipe 18. Since the air temperatures inside and outside the vehicle are different, the temperature detector 19 can detect the temperature of the drawn-in air, and according to the signal of the temperature detector 19, control the heating power of the heating pipe 15, heat the air reasonably, monitor the temperature of the drawn-in air in real time, and transmit the data to the control system of the heating pipe 15 through the transmission cable 17.

[0050] The air supply mechanism also includes: an air guide plate 35, which is fixedly installed at the inner center of the rotating air outlet box 11, and a movable gear ring 13 is fixedly installed on the upper surface of the rotating air outlet box 11. A slide groove 31 is opened on the upper surface of the movable gear ring 13, and a slidable buffer ring 32 is arranged inside the slide groove 31. The upper surface of the buffer ring 32 is fixedly connected to the bottom surface of the box body 1, and a motor box 33 is also fixedly installed on the side surface of the box body 1. A drive motor 14 is arranged inside the motor box 33, and a meshing gear 34 is arranged at the end of the bottom output shaft of the drive motor 14. The meshing gear 34 is engaged with the teeth on the upper surface of the movable gear ring 13, so as to drive the movable gear ring 13 and the rotating air outlet box 11 to rotate.

[0051] By driving the motor 14 to rotate, the meshing gear 34 is driven to mesh with the teeth of the movable gear ring 13, so that the rotating air outlet box 11 rotates on the bottom surface of the box body 1, thereby changing the air supply direction. When the rotating air outlet box 11 rotates, the fan plate 12 can help enhance the air supply effect and make the hot air more evenly distributed in the car.

[0052] The lifting assembly also includes two electric telescopic rods 4, which are fixedly installed on the bottom surface of the fixed top cover 3. Two fixed connecting plates 5 that cooperate with the electric telescopic rods 4 are fixedly installed on the two side surfaces of the bottom plate 2. The electric telescopic rods 4 can be extended or retracted by signal control, thereby driving the equipment to rise or fall.

[0053] By sending control signals using a remote control device, the electric telescopic rod 4 can be extended or retracted, thereby driving the entire device to rise or fall inside the train compartment, which is convenient for maintenance and installation. The fixed connecting plate 5 is connected to the telescopic end of the electric telescopic rod 4 to ensure the stability of the equipment during the lifting process.

[0054] The working principle of the present invention is:

[0055] When in use, an external air inlet 29 and an internal air inlet 30 are respectively provided at both ends of the ventilation duct 7, allowing air to be sucked in from outside or inside the car. The small motor 39 drives the sliding support rod 45 to move through the rotating disk 40, and further drives the lifting movable rod 44 to lift and lower, so that the toothed disk 36 drives the cover plate 21 to rotate, thereby switching the air inlet source to ensure the closure and opening of the air inlet. The filter plate 9 is removed from the bottom of the device through the rotatable buckle plate 10 and the snap fit. At the same time, the filters on both sides can filter impurities in the air. The top air duct 8 is fixedly installed on the top surface of the car to provide an external air inlet channel for the ventilation duct 7.

[0056] The odor filter box 20 of the air filter assembly can be easily taken out through the pull-out plate 6. It contains an air filter 24, an activated carbon plate 25, a photocatalyst plate 27 and an ultraviolet lamp holder 28, which perform preliminary filtration of the air, absorb odors, decompose organic pollutants and sterilize and disinfect in turn. When cleaning and replacing internal components, the staff can turn the control knob 22 to trigger the top block to drive the movable card plate 23 to move, thereby locking and unlocking the pull-out plate 6.

[0057] The exhaust fan 16 draws air from the air inlet mechanism through the air supply pipe 18 and sends it to the heating pipe 15 for heating. The heating pipe 15 controls the heating power of the heating pipe 15 through the transmission cable 17 according to the air temperature detected by the temperature detector 19 to ensure that the output air temperature is appropriate.

[0058] The rotating air outlet box 11 drives the meshing gear 34 to mesh with the movable gear ring 13 through the driving motor 14, so that the rotating air outlet box 11 rotates on the bottom surface of the box body 1, thereby changing the air supply direction. The air guide plate 35 is located inside the rotating air outlet box 11 to ensure that the hot air is evenly delivered from each air outlet slot of the air outlet box 11. The fan plate 12 can enhance the air supply effect when rotating, so that the hot air is evenly distributed in the car.

[0059] The electric telescopic rod 4 can be extended or retracted through signal control when maintenance and cleaning are needed, driving the entire equipment to rise or fall inside the car, which is convenient for maintenance and installation. The fixed connecting plate 5 is connected to the telescopic end of the electric telescopic rod 4 to ensure the stability of the equipment during lifting.
