Description

  The present invention provides cooling of a heat source such as a heat-generating component housed in a housing, an intake port and an exhaust port are provided in the housing, and cooling air taken from the intake port is discharged from the exhaust port by a fan inside the housing. The present invention relates to a projector with forced exhaust and a device with a heat source such as a video deck or personal computer with a built-in hard disk.

  In general, a projector has an input terminal portion and an intake port on the front surface of a housing constituting the apparatus main body, a connection terminal portion and an exhaust port for connecting a power cord on the rear surface, and a projection lens portion on one of the left and right side surfaces of the housing. And an exhaust fan for forcibly exhausting air for cooling the light source lamp from the exhaust port.

  In such a conventional projector, when an object is placed close to the exhaust port of the housing, or when the rear surface of the housing is positioned close to a wall or an object, the exhaust port is blocked. There is a risk that the inside of the housing may become hot and the main body of the device may break down, and the object itself may be damaged by being heated, or may be burned by touching the object. was there.

  In order to cope with this, the following techniques have been proposed. The first is that the wind pressure rises as an obstacle approaches the exhaust port and a sensor provided near both the projection lens unit for projecting light from the lamp and the exhaust port provided near the projection lens. And a control unit that reduces the output of the lamp when the sensor senses this, and detects the presence of an obstacle by a change in the wind pressure, thereby preventing a failure of the projection lens and the projector itself (for example, Patent Document 1). ).

No. 2 includes a light source lamp mounted in a concave mirror, an exhaust fan for exhausting air that cools the light source lamp, a back cover having a vent hole, and a light shielding panel. This is to prevent the blockage (for example, Patent Document 2).
JP 2001-92014 A JP 2002-27361 A

  However, in Patent Document 1, since the wind pressure of hot air exhausted from the exhaust port is sensed, the influence of the obstacle when the obstacle approaches the intake port cannot be detected, and the wind pressure is sensed. A sensor is required as an additional part for this purpose, but this has a problem that it is relatively expensive and causes an increase in cost.

In Patent Document 2, a light-shielding panel is provided outside the back cover having a vent hole. However, if the distance between both of them is too large, the device will be enlarged, and there will be some restrictions on the design. For this reason, it is difficult to ensure a sufficient interval for circulating air, which causes a problem that exhaust efficiency is lowered.
Further, it is impossible to prevent an obstacle from being placed so as to close the gap between the back cover and the light shielding panel, and in this case, the exhaust efficiency is lowered.
Furthermore, in order to install the light shielding panel, the back panel must be enlarged to some extent, which, in combination with the necessity of a certain distance between the light shielding panel and the back panel, causes an increase in the size of the apparatus. there were.

Because it is necessary, the device will not be operated with the safety member blocking the exhaust port. However, if the connection terminal is provided at a position other than the exhaust port, connect the power cord to the connection terminal. Even in such a case, there is no need to extend the safety member to the outside of the housing, and therefore the device may be operated with the safety member blocking the exhaust port. This is prevented by providing.

Hereinafter, the present invention will be specifically described with reference to the drawings showing embodiments thereof.
The drawings show an example in which the apparatus with a heat source according to the present invention is applied to a projector. FIG. 1 is a perspective view of a housing showing a state where the safety member is in the storage position, and FIG. FIG. 3 is a perspective view of FIG. 2 as viewed from below, FIG. 4 is a perspective view of a state where a power cord is connected to the connection terminal portion, and FIG. 5 is a state where the housing is close to the wall. FIG. 6 is an operation explanatory view showing the outflow state of hot air exhausted from the exhaust port.

  In FIG. 1 to FIG. 6, reference numeral 1 denotes a housing constituting the projector main body, and an intake port 2 and an exhaust port 3 are formed on both front and rear surfaces of the housing 1.

  As shown in FIG. 3, the air inlet 2 is provided in a part of the lower portion of the front surface of the housing 1. An input connection terminal portion 4 for connecting an input connection cord (not shown) is provided on the upper portion of the front surface of the housing 1. On the other hand, the exhaust port 3 is provided over the entire range of the rear surface of the housing 1, and a connection terminal portion 6 for connecting the power cord 5 is provided at the lower corner of the exhaust port 3.

  Housed in the housing 1 are a light source lamp l (not shown) as a heat source and a fan f for circulating air for cooling the heat source through the intake and exhaust ports 2 and 3. A projection lens unit 7 is provided on the left side surface of the housing 1, and an operation key unit 8 is provided on the upper surface.

  Further, a safety member 9 formed from a plate body is attached to the lower edge of the exhaust port 3. The lower end of the safety member 9 is pivotally supported by the left and right side plates of the housing 1 so as to be rotatable. The safety member 9 can selectively take two positions: an extended position that extends to the outside of the housing 1 and a storage position that removably fits to the inner surface of the housing 1. The safety member 9 is formed to have a size approximately equal to the size of the rear surface of the housing 1. Therefore, in the storage position, the rear surface and the connection terminal portion 6 are closed by the safety member 9 so that they are not exposed to the outside.

  In order to disengage the safety member 9 from the exhaust port 3, a claw or a metal fitting is inserted into the gap between the safety member 9 and the inner surface of the exhaust port 3 and engaged with the safety member 9. What is necessary is just to rotate to the outward of the body 1. Alternatively, an engagement recess 10 may be formed on the upper end portion of the safety member 9 and a fingertip may be hung on the engagement recess 10.

  Alternatively, an engagement recess 11 that opens to the exhaust port 3 and exposes a part of the side surface of the safety member 9 may be formed on one or both of the left and right side plates of the housing 1. A notch portion 12 may be formed on the plate so that a part of the upper surface of the safety member 9 is exposed, or a handle (not shown) may be provided on the upper outer surface of the safety member 9.

Next, the operation of this embodiment will be described.
FIG. 1 shows the projector in a non-use state, and the safety member 9 is in the storage position fitted to the inner surface of the exhaust port 3. In this state, since the exhaust port 3 is blocked by the safety member 9, no foreign matter or the like enters the inside of the housing 1, and the connection terminal portion 6 is also blocked at the same time, so the power cord 5 is connected. I can't do that either.

  When the projector is used, as shown in FIGS. 2 and 3, unless the safety member 9 is detached from the exhaust port 3 and the connection terminal portion 6 is exposed to the outside, as shown in FIG. The power cord 5 cannot be connected to the connection terminal portion 6. Therefore, the projector cannot be used when the safety member 9 is in the storage position. When the projector is activated, the fan f is activated and external air is taken into the housing 1 from the air inlet 2, and the air taken in cools the light source lamp l and then becomes hot air and exhausts from the exhaust port 3. Is done.

  As shown in FIG. 5, even when the exhaust port 3 of the housing 1 approaches an object such as a wall during the operation of the projector, the safety member 9 first contacts the wall or the like. It will not be blocked by contact. When the safety member 9 is not provided, hot air immediately after exhaust from the exhaust port 3 directly contacts the floor surface. However, when the safety member 9 is provided, as shown in FIG. Furthermore, the hot air does not come into contact with the floor surface by being blocked by the safety member 9.

  By removing the power cord 5 from the connection terminal portion 6 after using the projector, it becomes possible to fit the safety member 9 to the inner surface of the housing 1, thereby saving space. Can do.

  FIG. 7 is an explanatory view when the inclination angle of the safety member 9 is adjusted by the leg portion, and FIG. 8 is an operation explanatory view showing a state where an object slides down on the safety member. 3, 7, and 8, reference numeral 13 denotes a leg portion provided on the bottom plate of the housing 1. The leg portion 13 is not necessarily provided, but when this is provided, the inclination angle of the safety member 9 with respect to the floor surface is adjusted by adjusting the height of the leg portion 13 as shown in FIG. be able to. By doing so, when an object is placed on the safety member 9, the object slides on the safety member 9 away from the exhaust port 3 as shown in FIG. Absent.

  The number of leg portions 13 is not particularly limited, but usually three are attached as shown in FIG. And these three leg parts 13 are arrange | positioned so that it may be located in the vertex of an equilateral triangle, considering the stability of the housing | casing 1 on a floor surface. In FIG. 3, one side of the equilateral triangle is substantially parallel to one side plate of the housing 1, but is not limited to this, for example, parallel to both front and rear surfaces of the housing 1. It is also possible to do so. By appropriately adjusting the heights of the three leg portions 13, the inclination angle of the safety member 9 can be arbitrarily adjusted. In addition, as an example of the leg part 13, a screw screw is mentioned, for example.

  FIG. 9 is a side view showing a state in which the safety member is provided on the upper edge of the exhaust port. Although the safety member 9 is provided at the lower edge of the exhaust port 3 in the above, it can also be provided at the upper edge of the exhaust port 3 as shown in FIG. In this case, the connection terminal 6 is positioned above the exhaust port 3 and the base end of the safety member 9 is supported by the power cord 5 from below. By doing so, the safety member 9 is inclined upward, so that the exhaust efficiency is better than when the safety member 9 is in a horizontal state or inclined downward.

  10 is a side view of a housing provided with a detection switch, and FIG. 11 is a side view showing a state where the safety member is rotated to the extended position in FIG. Although the connection terminal portion 6 is provided at the exhaust port 3 in the above, it can be provided at a position other than the exhaust port 3. However, in such a case, the possibility of operating the projector with the safety member 9 closing the exhaust port 3 cannot be excluded. Therefore, as shown in FIGS. 10 and 11, an operation enable signal that enables the projector to be operated is output only when the safety member 9 is detected to be in the extended position extended to the outside of the housing 1. Providing the detection switch 14 prevents the projector from operating when the safety member 9 is in the storage position.

  The detection switch 14 is provided on one inner surface of the left and right side plates of the housing 1, and when the protrusion 15 formed on the inner surface of the upper end of the safety member 9 contacts the detection switch 14, the detection switch 14 is operable. It is configured to output a signal.

  FIG. 12 is a perspective view showing another example of the safety member when the area of the exhaust port is small. Although the exhaust port 3 is provided over the entire range of the rear surface of the housing 1 in the above, it is not necessarily provided over the entire range, and may be provided only in a part of the rear surface. In this case, it is preferable that the connection terminal portion 6 is disposed in the region of the exhaust port 3 so that the connection terminal portion 6 is closed by the safety member 9 at the storage position of the safety member 9. Further, it is preferable that the size of the safety member 9 is also reduced corresponding to the area of the exhaust port 3.

  FIG. 13 is a perspective view showing an example in which the safety member is used as a transport handle, and FIG. 14 is a perspective view showing a state where the safety member is rotated to the extended position in FIG. Both figures show other examples of the safety member 9, and the safety member 9 is formed in a U shape or a U shape so that it can serve as a transport handle when carrying the housing 1. The closing portion constitutes the gripping portion 16, and the open end portion is pivotally supported on the left and right side plates of the housing 1. However, one open end of the U-shaped or U-shaped safety member 9 is expanded inward so that the connection terminal portion 6 arranged at the corner of the exhaust port 3 is closed, and the closed portion 17 Is forming.

  Note that the safety member 9 is not limited to the above-described shape, and for example, it is also possible to form an opening in a plate and put the hand on the opening. When the safety member 9 is also used as a handle as described above, it is not necessary to add a new part in the casing 1 that requires a transport handle.

  As described above, as shown in FIGS. 1 to 14, the safety member 9 is provided only on the rear surface of the housing 1. However, the present invention is not limited to this. The same safety member 9 can be provided on the front surface.

  However, since the intake port 2 is provided only in a part of the front surface, it is preferable that the size of the safety member 9 also corresponds to the area of the intake port 2. Further, when the safety member 9 is provided on the upper edge of the front surface, the input connection terminal portion 4 has an input connection cord (not shown) connected thereto supporting the safety member 9 from below, as shown in FIG. , It is arranged at a position where it can be inclined upward.

  The safety member 9 can be provided not only on the upper and lower edges of the exhaust port 3 but also on the left and right edges. Specifically, the safety member 9 is pivotally supported on the left and right side plates of the housing 1 in a double-sided manner that can be rotated left and right. In this case, a stopper (not shown) is provided on the side plate of the housing 1 so that the safety member 9 is fixed in the left and right expanded state.

  In the above, an example in which the apparatus with a heat source according to the present invention is applied to a projector has been described, but the present invention is not limited to this, for example, a video deck or a personal computer with a built-in hard disk or the like, In order to cool the heat source housed in the housing with air, any device having a structure in which an air inlet and an exhaust port are provided in the housing and air is circulated by a fan provided in the housing can be applied. .
