Problems solved by technology

When the projector is idle and a fan or heater is needed in the room, it is generally necessary to buy another one. The heating and cooling elements inside the projector are idle, but the projector does not have the function of a fan or heater. Therefore, the existing projectors do not have a wider range of functions

Abstract

The invention provides a projector. The projector comprises a light source, a fan and a processing device, wherein the processing device is electrically connected with the light source and the fan, and meanwhile, the processing device is used for receiving and processing an input signal and controlling the light source and the fan according to the input signal. When being in the normal projection mode, the projector projects a picture on a projection surface normally, and the processing device controls the light source and the fan to be started; when being in the fan mode, the projector does not project the picture, and the processing device controls the light source to be closed and controls the fan to be started; and when being in the fan heater mode, the projector projects a black picture, and the processing device controls the light source and the fan to be started. According to the projector, the processing device is used for controlling the light source and the fan, heating elements and radiating elements are used sufficiently, and the projector also has the functions of the fan and the warm heater besides common projection functions, so that the projector has wide using functions.

Description

technical field [0001] The invention relates to a projection device, in particular to a projection device with fan and heater functions. Background technique [0002] Projectors are necessary equipment for most modern enterprises and schools. There are components that generate a lot of heat inside the projector, such as DMD chips, power boards, bulbs, etc. In order to guide the heat to the outside of the projector, a fan is usually installed inside the projector as a cooling device. When the projector is working normally, the heat it emits is equivalent to a small heater. When the projector is idle and a fan or heater is needed in the room, it is generally necessary to buy another one. The heating and cooling elements inside the projector are idle, but the projector does not have the function of a fan or heater. Therefore existing projector also does not have more extensive use function. Contents of the invention [0003] The object of the present invention is to provid...
