Embodiment approach 1

[0038] Hereinafter, a projection-type image display device as an electronic device according to Embodiment 1 of the present invention will be described with reference to the drawings. In addition, in the following description, when referring to the up, down, left, and right directions or the front and rear directions, the up, down, left, and right directions or the front and rear directions in each drawing are referred to.

[0039] The projection-type video display device as the electronic equipment in this embodiment is a three-panel projection-type video display device, which has such figure 1 The box-shaped packing box 1 shown in the perspective view of the appearance. The packaging box 1 has leg portions 2 at four corners of the bottom, and is configured to suck air outside the equipment as cooling air from the bottom. In addition, in the packaging box 1, an air filter device is arranged at the air intake port 3 for introducing air outside the device into the device.

Embodiment approach 2

[0068] Next, with respect to the projection type video display device of the second embodiment, refer to Figure 4 The flow chart is explained. The projection-type video display device of the second embodiment is different from the projection-type video display device of the first embodiment in the cleaning operation process. The following description will focus on the cleaning operation step, which is different from the first embodiment.

[0069] The cleaning operation process of the second embodiment is as follows: Figure 4 As shown, steps S21 to S23 in this embodiment are the same as steps S11 to S13 in the first embodiment. The lamp lighting start button in the present embodiment is the operation switch of the operation unit 32 as in the case of the first embodiment. Then, when the lamp lighting start button is pressed to start the operation, first, the automatic cleaning operation of the air filter 11 is executed.

[0070] Next, the steady operation is performed afte...

Embodiment approach 3

[0075] Next, with respect to the projection-type video display device of the third embodiment, refer to Figure 5 and Image 6 The flow chart is explained. The projection-type video display device of the third embodiment differs from the projection-type video display device of the first embodiment in the cleaning operation process. The following description will focus on the cleaning operation step, which is different from the first embodiment.

[0076] The cleaning operation step of the third embodiment is as follows: Figure 5 As shown, as in the case of Embodiment 1, when the entire power supply unit 33 is connected to a power source such as a commercial power supply, it enters a so-called standby state in which the operation switch waits to be turned on (step S31 ), and it is determined whether or not the lamp lighting start is pressed. button (step S32). Furthermore, in the present embodiment, when the lighting start button is pressed (YES in step S32 ), the first aut...

Abstract

The invention provides an electronic device. This electronic device is equipped with an air filter at the air intake port where the cooling air is introduced, and even if the power is cut off at any time, the automatic cleaning operation of the air filter can be performed reliably. This electronic device is configured to install an air filter at an air intake port through which cooling air is introduced, and to automatically clean the air filter to prevent clogging of the air filter. Then, when the power supply is cut off during the cleaning operation process of the air filter, the unfinished cleaning operation process will be completed during the subsequent operation of the electronic device. For example, an automatic cleaning operation of an air filter is performed when the operation of a projection type video display device as an electronic device is started. In addition to this operation, when clogging of the air filter is detected, an automatic cleaning operation of the air filter may be performed.

Description

technical field [0001] The present invention relates to electronic equipment, and particularly to electronic equipment including an air filter device that automatically cleans an air filter. Background technique [0002] In conventional electronic equipment such as personal computers and projection-type image display devices, a method is adopted in which air outside the equipment for cooling components is sucked and blown as cooling air. In particular, in a projection-type image display apparatus, since the light source lamp used for the light source becomes high temperature, cooling air is used to cool various optical system equipment represented by the light source lamp. [0003] In addition, in such electronic equipment, an air filter is used in order to capture dust in the inhaled air. However, the trapped dust accumulates in the air filter over time, and clogging occurs. In addition, when the air filter is clogged, the amount of air to be introduced decreases and the ...
