Description

Technical Field

[0001] This utility model relates to the field of defrosting technology, specifically to a simple damper-type defrosting device. Background Technology

[0002] In cold winters, bus windshields are prone to frost buildup, obstructing the driver's view and leading to traffic accidents. This necessitates rapid defrosting of bus windshields. Existing defrosters often require opening a defrost damper to direct warm air at maximum power and volume onto the windshield for defrosting. However, if the defrost damper motor malfunctions, the defrosting function cannot be achieved, compromising safety. Furthermore, existing defrosting equipment is relatively complex and costly. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a simple damper-type defroster with a simple structure. The simple structure can achieve maximum airflow defrosting, while also ensuring that the defroster can use a portion of the airflow for defrosting in other functional modes, thus maximizing driving safety.

[0004] Specifically, this utility model discloses a simple damper-type defroster, comprising:

[0005] The housing assembly is provided with a defrost port and an air outlet, the defrost port facing the vehicle window and the air outlet facing the interior of the vehicle;

[0006] An air outlet assembly includes a heating component and a fan installed within a housing assembly, wherein the heating component is used for heating and the fan is used for air outlet;

[0007] The damper is rotatably mounted inside the housing assembly and is used to block the air outlet.

[0008] The advantages of adopting the above technical solution are that the defrost port is normally open, and the opening and closing of the air outlet is controlled by a damper. When defrosting is required, the maximum air volume is guaranteed for defrosting. After defrosting is completed, a portion of the air force is retained for defrosting. At the same time, the cab can also be heated. The structure is simple and ensures driving safety.

[0009] Furthermore, a support partition is provided inside the housing assembly, the fan is installed on the lower side of the support partition, and the support partition is provided with a through hole, which corresponds to the air outlet end of the fan.

[0010] The advantage of adopting the above technical solution is that the setting of the support partition plays a fixing role, and the setting of the holes ensures that the air force generated by the fan passes through the holes, thereby improving the utilization rate of the fan.

[0011] Furthermore, the heating assembly includes a mounting plate and a PTC heater, the mounting plate being mounted on the upper side of the fan, and the PTC heater being fixed on the mounting plate.

[0012] The advantages of adopting the above technical solution are that the PTC heater is safe, low-cost, easy to control temperature and heats up quickly, which speeds up the defrosting process and ensures safe use.

[0013] Furthermore, a return air damper and a fresh air damper are provided on the lower side of the housing assembly.

[0014] The advantage of adopting the above technical solution is that when the vehicle air conditioning is in recirculation mode, air is introduced through the return air door; when it is in external recirculation mode, air is introduced through both the fresh air door and the return air door. This not only replenishes the vehicle with fresh air but also ensures the intake air temperature.

[0015] Furthermore, the damper is connected to a rotating shaft, which is rotatable and connected to a motor, which drives the rotating shaft to rotate.

[0016] The advantage of adopting the above technical solution is that the opening and closing of the air outlet is achieved by driving the damper shaft to rotate by a motor, which is convenient to control and simple to install.

[0017] Furthermore, a baffle is provided on the lower side of the damper, and the baffle is provided with a retaining edge. When the damper is opened, the side of the damper contacts the retaining edge.

[0018] The advantage of adopting the above technical solution is that the purpose of setting the baffle is to ensure the position of the damper when it is open. When the damper is open, it contacts the baffle edge, and the lower side of the damper is blown by the wind. At this time, the baffle plays a limiting role, ensuring that the damper will not block the defrost port and ensuring that the defrost port is always open.

[0019] Furthermore, the defrost port includes two cylindrical outlets mounted on top of the housing assembly.

[0020] The advantage of adopting the above technical solution is that the defrost port is connected to the defrost position inside the vehicle body through a pipe, and the cylindrical outlet ensures the air volume and defrost efficiency.

[0021] Furthermore, the air outlet is a strip-shaped outlet, installed on the housing assembly, located on the side of the defrost port, and inclined.

[0022] The advantage of adopting the above technical solution is that the air outlet is designed to blow air into the vehicle, and the strip-shaped air outlet design ensures uniform airflow and improves comfort.

[0023] Furthermore, the return air door is equipped with a protective net.

[0024] The advantage of adopting the above technical solution is that the protective netting prevents debris from entering and clogging the internal air ducts of the casing.

[0025] Furthermore, the fresh air damper is connected to a rotating shaft, and both ends of the rotating shaft are rotatably fixed to the housing assembly. A filler is provided between the fresh air damper and the housing assembly.

[0026] The advantage of adopting the above technical solution is that the fresh air damper can also be opened and closed. When it is open, it is in external circulation mode, and the wind from the outside environment enters the car. When it is closed, it is in internal circulation mode, and the wind circulates inside the car. Attached Figure Description

[0035] The present invention will now be described in further detail with reference to the accompanying drawings.

[0036] like Figure 1-5 As shown, this utility model discloses a simple damper-type defroster, comprising:

[0037] The housing assembly 1 is provided with a defrost port 2 and an air outlet 3, wherein the defrost port 2 faces the vehicle window and the air outlet 3 faces the interior of the vehicle;

[0038] The air outlet assembly includes a heating component 4 and a fan 5 installed inside the housing assembly 1. The heating component 4 is used for heating, and the fan 5 is used for air outlet.

[0039] The damper 6 is rotatably mounted inside the housing assembly 1 and is used to block the air outlet 3.

[0040] The advantages of adopting the above technical solution are that the defrost port 2 is normally open, and the opening and closing of the air outlet 3 is controlled by a damper 6. When defrosting is required, the maximum air volume is guaranteed for defrosting. After defrosting is completed, a portion of the air force is retained for defrosting. At the same time, the cab can also be heated. The structure is simple and ensures driving safety.

[0041] In some implementations, a support partition 11 is provided inside the housing assembly 1, and a fan 5 is installed on the lower side of the support partition 11. The support partition 11 is provided with through holes 12, which correspond to the air outlet end of the fan 5. There are two fans 5 arranged symmetrically, which rotate after being powered on. There are also two through holes 12 to ensure the air volume. The support partition 11 is fixed to the housing assembly 1 with screws, which serves to fix and support it. The base on the fan 5 is locked and fixed to the support partition 11.

[0042] The support partition 11 serves to fix the fan, and the holes 12 ensure that the air force generated by the fan 5 passes through the holes 12, thereby improving the utilization rate of the fan 5.

[0043] In some implementations, the heating assembly 4 includes a mounting plate 41 and a PTC heater 42. The mounting plate 41 is fixedly mounted on the upper side of the fan 5, and the PTC heater 42 is fixed to the mounting plate 41. The PTC heater 42 can be locked in place for easy disassembly and maintenance. The PTC heater 42 has the advantages of safety, low cost, convenient temperature control, and rapid heating, which speeds up defrosting and ensures safe use.

[0044] Furthermore, a return air damper 13 and a fresh air damper 14 are provided on the lower side of the housing assembly 1. The return air damper 13 is provided with a protective net. The fresh air damper 14 is connected to a rotating shaft 15. The two ends of the rotating shaft 15 are rotatably fixed to the housing assembly 1. A filler made of sponge is provided between the fresh air damper 14 and the housing assembly 1. It is fixed around the opening of the housing assembly 1. A motor is provided on the outside of the housing assembly 1. The output end of the motor is connected to the rotating shaft 15 to control the opening and closing of the fresh air damper 14. When it is open, it is in external circulation mode, and the air from the outside environment enters the vehicle. When it is closed, it is in internal circulation mode, and the air circulates inside the vehicle.

[0045] When the vehicle's air conditioning is in recirculation mode, air is drawn in through the return air damper 13. When it is in external recirculation mode, air is drawn in through both the fresh air damper 14 and the return air damper 13. This not only replenishes the vehicle with fresh air but also ensures the intake air temperature and reduces energy consumption.

[0046] In some implementations, the damper 6 is connected to a rotating shaft 61, which is rotatable. The rotating shaft 61 is connected to a motor, which is mounted on the outside of the housing assembly 1. The motor drives the rotating shaft 61 to rotate, thereby opening and closing the damper. Multiple mounting blocks are provided on the side of the damper 6, and a passage is provided between the mounting blocks and the damper 6. The entire rotating shaft 61 passes through the passage, and both ends are rotatably fixed. The output shaft of the motor is connected to the rotating shaft 61, which drives the rotating shaft 61 to rotate. The rotating shaft 61 is located on the upper side of the damper 6, close to the air outlet 3. When the motor rotates, the damper 6 covers the air outlet 3, and the air outlet 3 is closed. When the motor rotates, the air outlet 3 opens. At this time, the air outlet 3 and the defrost port 2 open simultaneously, partially defrosting and partially blowing air to provide a warm driving environment.

[0047] Furthermore, a baffle 62 is provided on the lower side of the damper 6. The baffle 62 is fixedly installed on the mounting plate 41. The baffle 62 is provided with a retaining edge. When the damper 6 is opened, the side of the damper 6 contacts the retaining edge. The purpose of the baffle 62 is to ensure the position of the damper 6 when it is open. When the damper 6 is open, it contacts the retaining edge, and the lower side of the damper 6 is blown by the wind. At this time, the baffle 62 acts as a limit to ensure that the damper 6 does not block the defrost port 2, thus ensuring that the defrost port 2 remains open.

[0048] Furthermore, the defrost port 2 includes two cylindrical outlets installed on the top of the housing assembly 1 and communicating with the interior of the housing.

[0049] Defrost port 2 is connected to the defrost position inside the vehicle body via a pipe. The cylindrical outlet ensures sufficient airflow and defrosting efficiency.

[0050] In some implementations, the air outlet 3 is a strip-shaped outlet, fixedly installed on the housing assembly 1, also communicating with the interior, located on the side of the defrost port 2, and set at an angle.

[0051] The advantage of adopting the above technical solution is that the air outlet 3 is designed to blow air into the vehicle, and the strip-shaped air outlet 3 ensures uniform airflow and improves comfort.

[0052] During operation, when the vehicle requires defrosting, fan 5 rotates and PTC heater 42 operates to heat the air. At this time, damper 6 closes, and the defroster operates at maximum airflow. Once the windshield defrosting is complete, damper 6 opens, with some airflow directed towards the glass to prevent further frost buildup, and some airflow directed towards the driver to provide a warm driving environment.

[0053] This application eliminates the defrosting damper, meaning the defrosting port 2 remains constantly open. This avoids the dangerous situation of being unable to defrost in cold weather due to damper motor failure. When defrosting is needed, the damper 6 located at the air outlet 3 can be closed to achieve maximum airflow defrosting, allowing switching between single defrosting and defrosting with personnel blowing. With the defrosting port 2 constantly open, as long as the defroster is on, warm air is continuously blown onto the windshield, fundamentally solving the frost problem and greatly improving safety.

[0054] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
