Description

Technical Field

[0001] The utility model relates to the technical field of exhaust devices for RVs, and specifically to a device for regulating the indoor constant temperature of RVs. Background Art

[0002] An RV is a special type of vehicle that combines the functions of a house and a vehicle. It is a movable vehicle with essential household facilities. The temperature inside the RV changes with the external temperature. Moreover, when the sun shines directly on the vehicle body, since the vehicle body is sealed, the temperature inside the vehicle is often higher than the outside temperature, making it unbearable.

[0003] The most convenient way is to open the windows and exhaust fans to achieve the replacement of internal and external air to reduce the temperature inside the vehicle. However, the exhaust capacity of the exhaust fan of the RV is limited and cannot quickly exhaust the temperature inside the vehicle. When the temperature inside the vehicle is high, it is unable to quickly exhaust the air inside the vehicle. For this reason, we propose a device for regulating the indoor constant temperature of RVs. Summary of the Utility Model

[0004] Aiming at the deficiency of the limited exhaust air volume of the existing RV exhaust fan, the utility model provides a device for regulating the indoor constant temperature of RVs, which has the advantages of arranging multiple fan impellers on the roof for exhaust, with higher pressure and larger exhaust air volume compared to traditional fan blades, and solves the problems raised in the above background art.

[0005] To achieve the above objectives, the utility model is realized through the following technical solutions: A device for regulating the indoor constant temperature of RVs includes a mounting plate, and an exhaust mechanism is installed on the top of the mounting plate. The exhaust mechanism includes two fan covers symmetrically installed on the mounting plate;

[0006] The two fan covers are coaxially arranged, and a transmission shaft is coaxially arranged between them. The two ends of the transmission shaft are respectively rotatably installed at the center of the side surface of the fan cover. The ends of the transmission shaft extend into the fan cover, and fan impellers are installed at their ends. An air outlet is installed on the top of each fan cover;

[0007] Air ducts communicating with the inside are installed on the side surfaces of the two inlet fan covers, and the other ends of the air ducts are connected to the mounting plate; wherein, the mounting plate is installed on the roof of the RV, and each air duct is communicated with the inside of the RV;

[0008] It further includes a driving motor arranged on the mounting plate, and the driving motor is connected to the transmission shaft through a transmission mechanism.

[0009] Preferably, an exhaust duct is installed on the air outlet. The exhaust duct is arc-shaped and its end is inclined downward.

[0010] Preferably, the number of air ducts on the fan cover is two, which are symmetrically arranged on both sides of the transmission shaft. The two ends of the air ducts are respectively connected to the fan cover and the mounting plate through flanges.

[0011] Preferably, two support legs are symmetrically installed at the bottom of the fan cover. A connecting seat is provided at the bottom of the support leg, and the connecting seat is connected to the mounting plate.

[0012] Preferably, sealing end caps are respectively installed at the two ends of the two fan covers that are far away from each other.

[0013] Preferably, the number of exhaust mechanisms is at least two, and they are arranged at intervals on the mounting plate. The transmission shafts in two adjacent exhaust mechanisms are also connected through a transmission mechanism.

[0014] Preferably, the transmission mechanism includes pulleys respectively installed on the middle of the transmission shaft and the rotating shaft of the driving motor, and the pulleys are connected by a belt.

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 to 3 , the present invention provides a technical solution: a device for regulating the indoor temperature of a recreational vehicle, including a mounting plate 1, and an exhaust mechanism is installed on the top of the mounting plate 1. The exhaust mechanism includes two fan housings 3 symmetrically installed on the mounting plate 1;

[0025] The two fan housings 3 are coaxially arranged, and a drive shaft 6 is coaxially arranged between them. The two ends of the drive shaft 6 are respectively rotatably installed at the center of the side of the fan housing 3. The ends of the drive shaft 6 extend into the fan housing 3, and fan impellers 12 are installed at their ends. Air outlets are installed on the top of each fan housing 3; air ducts 2 communicating with the inside are installed on the sides of the two intake fan housings 3, and the other ends of the air ducts 2 are connected to the mounting plate 1;

[0026] Specifically, in the actual operation process, as Figure 3 shown, the mounting plate 1 is installed on the roof of the recreational vehicle, and each air duct 2 communicates with the inside of the recreational vehicle; a drive motor 10 is also provided on the mounting plate 1, and the drive motor 10 is connected to the drive shaft 6 through a transmission mechanism, so that the drive motor can drive the drive shaft 6 to rotate rapidly. At the same time, the fan impellers 12 are respectively driven to rotate at both ends of the drive shaft 6. Here, the fan housing 3 and the fan impeller 12 form an exhaust fan, and the fan impeller is used as the power for exhausting air. The impeller will generate high pressure when rotating, which is used to accelerate the discharge of air.

[0027] In the actual operation process, the temperature inside the recreational vehicle is high. In order to better discharge the temperature inside the vehicle quickly, the number of exhaust mechanisms can be set to multiple, as Figure 1 shown, the number of exhaust mechanisms is at least two and they are arranged at intervals on the mounting plate 1. The drive shafts 6 in adjacent two exhaust mechanisms are also connected through a transmission mechanism;

[0028] The transmission mechanism includes pulleys 11 respectively installed in the middle of the transmission shaft 6 and on the rotating shaft of the drive motor 10. The pulleys 11 are connected by a belt, and the pulleys 11 can be replaced with synchronous pulleys or sprockets for use;

[0029] Therefore, when the drive motor 10 rotates, it can drive multiple transmission shafts 6 to rotate simultaneously. And multiple transmission shafts 6 drive each fan impeller 12 to rotate simultaneously. Through multiple fan impellers 12, the air exhaust flow rate can be increased, and when in use, the hot air inside the RV can be quickly exhausted to the outside, allowing new air from the outside to enter, thereby achieving the cooling effect.

[0030] Furthermore, the present application also improves the air outlet. An exhaust duct 4 is installed on the air outlet. As Figure 3 shown, after the mounting plate 1 is installed on the roof, in order to prevent rainwater from flowing back into the exhaust duct 4, the exhaust duct 4 is designed to be arc-shaped and its end is inclined downward, and the exhaust duct 4 extends in the opposite direction of the vehicle head, so as to avoid rainwater flowing into the vehicle when the vehicle is driving.

[0031] Furthermore, in order to increase the air exhaust volume of the fan impeller, the number of air guide pipes 2 on the fan cover 3 is two and they are symmetrically arranged on both sides of the transmission shaft 6. The air guide pipes 2 are L-shaped bent pipes, and both ends of the air guide pipes 2 are connected to the fan cover 3 and the mounting plate 1 through flanges respectively; at the same time, two support legs 8 are symmetrically installed at the bottom of the fan cover 3. A connecting seat 9 is provided at the bottom of the support leg 8, and the connecting seat 9 is connected to the mounting plate 1. The flanges and the connecting seat 9 are both fastened by bolts, which is convenient for disassembly and installation;

[0032] Sealing end caps 7 are respectively installed at the two ends of the two fan covers 3 that are far away from each other. The sealing end caps 7 are fastened to the edge of the fan cover 3 by bolts, which is convenient for opening the sealing end cap to check and maintain the fan impeller.

[0033] As Figure 1 shown, in the actual operation process, the fan covers 3 on both sides should be located on both sides of the roof. Since there is a certain distance between the fan covers 3, in order to make the transmission shaft 6 more stable, the middle of each transmission shaft 6 is rotatably installed inside the top of the support seat 5, and the bottom of the support seat 5 is connected to the mounting plate 1, so that the middle of the transmission shaft 6 is supported to prevent the transmission shaft 6 from bending and deforming.

[0034] As Figure 2 shown, a protective cover 13 is also provided on the mounting plate 1. The protective cover 13 is located between the fan covers 3, and the bottom of the protective cover 13 is connected to the mounting plate 1. The protective cover 13 can protect the pulleys, prevent foreign objects from entering between the pulleys, and avoid the pulleys from being exposed to wind, sun and rain. The provided protective cover can also reduce the noise of the drive motor, and minimize the impact on the interior of the vehicle after the drive motor is turned on.

[0035] Based on the above embodiments, further optimization can be carried out. Here, the fan impeller can also be replaced by fan blades. After multiple fan blades are turned on simultaneously, the air flow can also be increased.

[0036] Based on the above embodiments, further optimization can be carried out. The position of the protective cover 13 close to the vehicle head is streamlined to reduce wind resistance.

[0037] Based on the above embodiments, further optimization can be carried out. A controller is installed on the mounting plate 1. The controller is connected to the drive motor through a wire, and the controller is also connected to the vehicle power supply device through a wire. The controller is also connected to two temperature sensors through wires. One temperature sensor is installed outside the vehicle and is used to sense the external temperature of the vehicle. The other temperature sensor is installed inside the vehicle and is used to sense the internal temperature of the vehicle. The external temperature and the internal temperature are compared, and the controller automatically controls the drive motor to exhaust air. When the internal temperature of the vehicle drops to a preset value, the speed can be reduced or the machine can be stopped.

[0038] Moreover, a switch for controlling the start and stop of the drive motor can be installed inside the vehicle. The switch is connected to the controller through a wire, and the control is the main machine or the PCB control main board.

[0039] Finally, in order to prevent the wind noise from being transmitted into the vehicle through the exhaust duct 4, a sealing plate is provided on the mounting plate 1 corresponding to the air duct 2, and it can be closed when the vehicle is running.
