Description

Technical Field

[0001] The present invention relates to the technical field of projectors, and in particular to a purification, cooling and dehumidification device, method and system for projectors. Background Art

[0002] A large amount of heat is generated when the projector is working, causing the temperature of the projector's components to rise. High temperature will reduce the projector's projection brightness and the quality of the projection picture. When the internal temperature reaches 85 degrees Celsius, the projector automatically starts an alarm, turns off the light source, and causes a projection accident. Therefore, the projector needs to be cooled internally. The optimal operating humidity range of the projector is 55%RH~65%RH. Too high humidity can easily cause problems such as short circuit and corrosion in the projector circuit. Too low humidity can easily cause static electricity to accumulate in the circuit and be interfered by static electricity. The optical components of the projector are easily contaminated by dust, resulting in reduced projection picture quality and even damage to the optical components. At the same time, the combined effects of high temperature, humidity and dust on the projector will reduce the service life of the projector. From an environmental protection perspective, there is a need to reduce energy consumption when the projector and projection auxiliary equipment are working.

[0003] Currently, the equipment available on the market can only meet the cooling or purification needs of the projector. The projector purification equipment on the market is mainly used to meet the purification needs of the projector. This type of equipment only has purification function, no cooling function and dehumidification function, and cannot meet the purification, cooling and humidity needs of the projector at the same time.

[0004] Another type of equipment is projector cooling equipment. The principle of this type of cooling equipment is: the equipment is a closed cavity, and is equipped with household air-conditioning refrigeration equipment. It only cools the internal space of the equipment and cannot purify the air inside the equipment. In addition, the heat generated by the projector when working is relatively large, at least more than 2000W, which requires the equipment to have a larger cooling power and consume more energy.

[0005] Generally, the cables of purification or cooling equipment are sealed with adapter plugs, which reduces the reliability of the electrical connection of the cables. The projector lens is sealed with a silicone sleeve-like structure, but this method has a narrow scope of application. For example, some projector lenses will automatically rotate when the image quality is adjusted, which will cause the silicone sleeve to create resistance to the lens rotation, resulting in the risk of the lens not rotating into place.

[0090] It should be noted that the sealing material is used to seal the gap between the two parts. Each component of the projector purification, cooling and dehumidification equipment can be disassembled, which is convenient for the maintenance of the projector and the equipment; the wire sealing component 130 is a separate component, and when the filter cooling component 120 is disassembled, the wire sealing component 130 does not need to be disassembled.

[0091] In addition, the present application also provides a projector purification, cooling and dehumidification system, including: a projector 200, and the projector purification, cooling and dehumidification device 100 described above. Figure 8As shown, the projector 200 may be an existing device in the art. Generally, the projector 200 includes a housing, and the housing may be divided into a projector light source cavity 220 for placing the projector light source and a projector optical engine cavity 230 for placing the projector optical engine. A first air inlet 250 is provided for the projector light source cavity 220 on one side wall of the housing, and a second air inlet 260 is provided for the projector optical engine cavity 230 on the other side wall of the housing, and an air outlet is also provided on the housing.

[0092] The working principle of a projector purification, cooling and dehumidification equipment is as follows:

[0093] When in use, the projector 200 is first placed in the accommodation space of the projector purification, cooling and dehumidification device 100, so that the side wall of the projector 200 with the first air inlet 250 faces the air inlet of the box (i.e., toward the right panel 121), and there is a gap between the side wall of the projector 200 with the projector lens 240 and the second air inlet 260 faces the rear panel 181 of the box, and the side wall of the projector 200 with the air outlet (not shown in the figure) faces the air outlet of the box (i.e., toward the left panel 161). Multiple wires connected to the projector 200 are led out through the wire holes 134 on the wire sealing panel 133.

[0094] like Figure 4As shown, the inlet airflow B outside the projector purification cooling dehumidification device enters through the protective net 125 of the filter component under the action of the inlet fan 127, flows through the filter net 126, and flows out from the air inlet fan 127. The inlet airflow B is filtered into a clean airflow. The clean airflow flowing to the projector 200 is divided into two paths, one is the projector light source cavity airflow, and the other is the cooling component inlet airflow. The projector light source cavity airflow enters the projector light source cavity 220 inside the projector 200 from the first air inlet 250 of the projector, and after dissipating the heat for the projector light source, it flows out from the air outlet of the projector 200, and is discharged from the exhaust fan 162 through the exhaust duct member 163. The outlet airflow F discharged by the exhaust fan 162 flows into the external environment. The inlet air flow C of the cooling component is subjected to the negative pressure caused by the fan in the accommodating chamber of the cooling component 124, and enters the cooling component 124 from the air inlet of the cooling guide component. The cooling component 124 cools down and dehumidifies the inlet air flow C of the cooling component and converts it into cooling air flow. After the cooling air flow flows out along the cold air duct member 128, it returns to the gap between the air outlet of the cooling guide component and the rear panel 181 in the accommodating space, and flows along the gap to the second air inlet 160 of the projector 200, and enters the projector optical engine cavity 230 inside the projector 200 from the second air inlet 260, and exchanges heat with the projector optical engine 210. The temperature of the projector optical engine 210 decreases, and the temperature of the cooling air flow increases. The cooling air flow with increased temperature flows out from the air outlet of the projector 200, and is discharged from the exhaust fan 162 after passing through the exhaust duct member 163. The outlet air flow F discharged by the exhaust fan 162 flows into the external environment. In the present application, the projector purification cooling and dehumidification equipment only provides cooling airflow to the projector optical engine 210, which can reduce the energy consumption of the equipment. It should be noted that the gap between the air outlet of the cooling guide component and the rear panel 181 refers to the second side of the cold air duct member 128 and the space formed by the side wall of the projector 200 facing the rear panel 181 and the rear panel 181, and the gap connects the air outlet of the cooling guide component and the second air inlet 260 of the projector 200. Among them, an appropriate gap is left between the second side of the cold air duct member 128 and the projector 200, and the size of the gap should not affect the flow direction of the cooling airflow from the air outlet of the cooling guide component to the second air inlet 260.

[0095] In summary, the projector purification, cooling and dehumidification equipment, method and system provided by the present application can simultaneously meet the requirements of the projector for air purification, temperature, humidity and dust prevention by providing a filtering and cooling component and an exhaust component; by providing a wire sealing component, the wire can be directly sealed without an adapter plug, thereby avoiding the reduction in reliability of the electrical connection caused by the wire adapter. All components of the projector purification, cooling and dehumidification equipment of the present application can be disassembled and assembled, which is convenient for the maintenance of the projector and the equipment.
