Description

  The present invention relates to an electronic device for notifying information related to a clogging state of a filter disposed in an opening for taking in outside air formed in a casing, an information notifying method for notifying the information, and clogging of the filter. The present invention relates to a projector that projects a notification video capable of reporting information related to a state, and a notification video projection method that projects the notification video.

An electronic device such as a projector that has a high temperature inside the housing generally has a function of cooling the inside of the housing by taking outside air into the housing and blowing the outside air with a blower fan. Further, a filter for preventing intrusion of dust or the like is generally provided in the opening for taking in outside air. In this case, dust or the like may adhere to the filter due to the use of the electronic device, and the filter may become clogged. There is a risk of failure. For this reason, this type of electronic device detects parameters that can identify the clogged state of the filter (such as the current value flowing through the fan and the amount of air flow), and the clogged state is reached when the parameter reaches a predetermined value. (For example, a filter replacement warning mechanism disclosed by the applicant in Japanese Patent Application Laid-Open No. 2004-63993) is provided.
Japanese Unexamined Patent Publication No. 2004-63993 (pages 6-13 and 3-6)

  However, the above-described conventional electronic devices have the following problems to be improved. That is, in this type of electronic device, information prompting cleaning or replacement of the filter is notified when the above parameter reaches a predetermined value. On the other hand, the progress speed of clogging of the filter varies greatly depending on the usage pattern (usage location and frequency) of the electronic device. For example, a projector as an electronic device is installed in a lobby where many people frequently enter and exit and is operated for a long time (hereinafter, such a usage pattern is also referred to as a “first usage pattern”). The filter clogs in a short period of time. On the other hand, in a usage pattern in which a projector is occasionally used in a dust-free conference room or the like (hereinafter, this usage pattern is also referred to as a “second usage pattern”), even if it is used for a long time, a filter Is hard to clog. For this reason, in the first usage pattern, it is necessary to clean and replace the filter promptly because the period from when the above information is notified until the operation of the electronic device is hindered is short. On the other hand, in the second usage pattern, since this period is long, the electronic apparatus can be used without any trouble without performing cleaning or replacement of the filter for a while even after the information is notified. There is. However, in conventional electronic devices, information prompting the cleaning or replacement of the filter is uniformly notified when the above parameter reaches a predetermined value regardless of the usage form. As a result of being difficult to judge, the function of notifying this information is not being used effectively, and improvement of this point is desired.

  In addition, in a projector as a conventional electronic device, a notification image including a message prompting cleaning or replacement of the filter is projected as one form of notification of the above information. In this case, if the notification video is always projected, when the video (source video) based on the external video signal (source signal) is projected, the notification video is projected on the source video and the source video becomes difficult to see. It is not preferable. For this reason, a conventional projector generally projects a notification video for a predetermined short time at a timing such as when the power is turned on, and then stops projecting the notification video. However, in this projection method, since the time for projecting the notification image is limited to a predetermined short time, the notification image may be overlooked. For this reason, the conventional projector has an inconvenience that the user may miss the opportunity to clean or replace the filter by overlooking the notification image, which may cause a failure, and improvement of this point is also desired. .

  The present invention has been made in view of the problem to be improved, and provides an electronic device, an information notification method, a projector, and a notification video projection method that can effectively use a notification function of information related to a clogged state of a filter. The main purpose is to provide. It is another object of the present invention to provide a projector that can eliminate inconveniences when projecting a notification image that can notify information related to the clogging state of the filter.

  In order to achieve the above object, an electronic apparatus according to the present invention detects a parameter capable of specifying a clogging state of a housing and a filter disposed in an opening for taking in outside air formed in the housing. An electronic device comprising: a detection unit; a notification unit that notifies information related to the clogged state; and a control unit that notifies the information to the notification unit when the parameter satisfies a predetermined condition. An operation unit capable of setting operation for setting the predetermined condition is provided, and the control unit notifies the information when the parameter satisfies the set condition.

  In the information notification method according to the present invention, the parameter that can specify the clogging state of the filter disposed in the opening for taking in outside air formed in the casing of the electronic device satisfies a predetermined condition. And an information notification method for notifying information related to the clogged state, wherein the information is notified when the predetermined condition set by a setting operation using an operation unit is satisfied.

  According to this electronic device and the information notification method, when the parameter satisfies the predetermined condition set by the setting operation using the operation unit, the information related to the clogging state of the filter is notified, for example, The user himself / herself sets the conditions so that the information is notified early in the usage form that is easily clogged, and sets the conditions so that the information is notified late in the usage form that is difficult to clog. Conditions can be arbitrarily set according to the usage pattern of the electronic device. Therefore, according to the electronic device and the information notification method, the user who has performed the setting can surely recognize the appropriate time when the filter should be actually cleaned or replaced. Compared with a conventional electronic device in which information related to clogging is notified when one condition is satisfied, the information notification function related to the clogging state of the filter can be used sufficiently effectively.

  Moreover, the electronic device according to the present invention includes a display unit as the notification unit in the electronic device described above, and the control unit can notify the information when the parameter satisfies the set condition. A notification image is displayed on the display unit.

  According to this electronic device, for example, by displaying a notification image capable of notifying information related to the clogging state of the filter on the display unit, for example, turning on the LED or notifying information about clogging by voice guidance, In comparison, the clogging state of the filter can be more reliably notified to the user.

  The projector according to the present invention includes a projection unit that projects an image, a housing in which the projection unit is disposed, and a filter disposed in an opening for taking in outside air formed in the housing. A detection unit that detects a parameter capable of specifying a clogging state; a control unit that causes the projection unit to project a notification image capable of notifying information related to the clogging state when the parameter satisfies a predetermined condition; The control unit includes an operation unit capable of performing a setting operation for setting the predetermined condition, and the control unit projects the notification video when the parameter satisfies the set condition.

  Further, the notification image projection method according to the present invention is such that the parameter that can specify the clogging state of the filter disposed in the opening for taking in outside air formed in the housing of the projector satisfies a predetermined condition. Further, a notification video projection method for projecting a notification image capable of notifying information related to the clogging state onto a projection unit disposed in the housing, wherein the notification image projection method is set by a setting operation using an operation unit The notification image is projected when the parameter satisfies a predetermined condition.

  According to the projector and the notification image projection method, the notification image capable of notifying information related to the clogging state of the filter is projected when the parameter satisfies a predetermined condition set by the setting operation using the operation unit. Therefore, for example, in the usage mode that is likely to be clogged, the condition is set so that the notification image is projected earlier, and in the usage mode that is difficult to clog, the condition is set so that the notification image is projected later. As such, the user can arbitrarily set conditions according to the usage pattern of the projector. Therefore, according to the projector and the notification video projection method, the user who has made the setting can surely recognize the exact time when the filter should be actually cleaned or replaced. Compared with a conventional electronic device in which information related to clogging is notified when one condition is satisfied, the information notification function related to the clogging state of the filter can be used sufficiently effectively. In addition, in the projector and the notification video projection method, information on clogging is notified by projecting the notification video, and therefore, for example, compared with a method of notifying information on clogging by turning on an LED or by voice guidance. Thus, it is possible to more reliably notify the user of the clogged state of the filter.

  The projector according to the present invention includes a projection unit that projects an image, a housing in which the projection unit is disposed, and a filter disposed in an opening for taking in outside air formed in the housing. A detection unit that detects a parameter capable of specifying a clogging state; a control unit that causes the projection unit to project a notification image capable of notifying information related to the clogging state when the parameter satisfies a predetermined condition; The control unit is configured so that the parameter satisfies the predetermined condition and the video signal is not input or the input video signal does not correspond to the projection of the video by the projector. When the signal is not supported, the notification image is continuously projected.

  According to the projector, when the parameter satisfies a predetermined condition and the video signal is not input or when the input video signal is an unsupported signal, the notification video is continuously projected, Unlike a conventional projector that projects a notification image only for a short time, it is possible to reliably prevent the occurrence of a failure by passing the time to clean or replace the filter by overlooking the notification image.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of an electronic device, an information notification method, a projector, and a notification video projection method according to the invention will be described with reference to the accompanying drawings. A projector 1 shown in FIGS. 1 and 2 is an example of an electronic apparatus and a projector according to the present invention, and includes a main body 2 and a remote controller 3 as shown in FIG. As shown in FIG. 3, the main body 2 includes a video signal processing unit 11, a storage unit 12, a projection unit 13, a blower fan 14, an air volume detection unit 15, a light receiving unit 16, a control unit 17, and each of these components. A housing 2a (see FIGS. 1 and 2) to be accommodated (or arranged) is provided. In this case, as shown in both figures, the housing 2a has an intake port (opening in the present invention) 2b for taking in outside air (air outside the housing 2a) used for cooling inside the housing 2a, and the housing 2a. An exhaust port 2c for discharging the air in the body 2a to the outside is formed. In addition, an air filter (a filter in the present invention) 100 for removing dust in the air and preventing entry of dust into the housing 2a is attached to the air inlet 2b.

  The video signal processing unit 11 converts the video signal S1 input from the outside via the signal terminal 11a (see FIG. 2) disposed on the back surface of the housing 2a into video data Di for video projection and outputs the video data. Further, the video signal processing unit 11 generates video data Di for projecting a menu video P2 (see FIG. 5), a setting video P3 (see FIG. 6), and a notification video P4 (see FIG. 7), which will be described later. Output. The storage unit 12 stores a reference value W0 used in the notification video projection process 50 (see FIG. 8) executed by the control unit 17, setting contents to be described later, and the like.

  The projection unit 13 corresponds to a projection unit, a notification unit, and a display unit in the present invention, and includes a light source and a light modulation element (not shown) disposed inside the housing 2a (for example, a liquid crystal light valve, DMD (Digital Micromirror Device). )), And a projection lens 13a shown in FIG. 1, and outputs projection light L (see FIG. 4) light-modulated on the basis of video data Di output from the video signal processing unit 11. Is projected onto the screen 200 (see FIG. 4). In this case, projection of the notification video P4 by the projection unit 13 corresponds to information notification and display of the notification video in the present invention. DMD is a trademark of Texas Instruments Incorporated.

  The blower fan 14 is disposed in the vicinity of the air filter 100 inside the housing 2 a and blows outside air taken in from the air inlet 2 b (through the air filter 100) toward the projection unit 13. The air volume detection unit 15 is an example of a detection unit according to the present invention, and is disposed in the housing 2a of the projector 1, detects the air volume W1 in the vicinity of the blower fan 14, and outputs a detection signal S2. In this case, the air volume W1 is an example of a parameter in the present invention, and the value becomes smaller as the degree of clogging of the air filter 100 is higher (as the air filter 100 is clogged). For this reason, it becomes possible to identify the clogged state of the air filter 100 based on the value of the air volume W1. The light receiver 16 receives the infrared signal S3 output from the remote controller 3 and outputs an operation signal S4 corresponding to each button of the remote controller 3.

  The control unit 17 controls each component constituting the projector 1. In addition, the control unit 17 causes the projection unit 13 to project an image based on the image signal S1 (image data Di) (hereinafter also referred to as “source image P1”: see FIG. 4). Further, the control unit 17 causes the projection unit 13 to project the menu image P2 and the setting image P3 in response to an operation of a menu button 22 or a jog button 23 of the remote controller 3 described later. In this case, the menu image P2 and the setting image P3 are images for setting the contents and conditions of various processes performed by the projector 1, and the setting contents set according to the guidance by these images P2 and P3. Is stored in the storage unit 12 by the control unit 17. In addition, the control unit 17 causes the projection unit 13 to project the notification video P4 according to the notification video projection method according to the present invention by executing the notification video projection processing 50. In this case, the notification video P4 is a video for notification of information indicating that the air filter 100 is clogged (an example of information related to the clogging state in the present invention). It is composed of still images including clogging and characters that prompt the cleaning or replacement of the air filter 100.

  The remote controller 3 corresponds to an operation unit in the present invention, and includes various buttons such as a power button 21, a menu button 22, and a jog button 23 as shown in FIG. 1, and each button is operated when these buttons are operated. An infrared signal S3 corresponding to is output.

  Next, an example of how to use the projector 1 and the operation of the projector 1 at that time will be described with reference to the drawings.

  In the projector 1, when the power button 21 of the remote controller 3 is operated, the remote controller 3 outputs an infrared signal S3 corresponding to the power button 21. Next, the light receiving unit 16 receives the infrared signal S3 output from the remote controller 3 and outputs an operation signal S4 corresponding to the power button 21. Subsequently, the control unit 17 initializes each unit constituting the projector 1 according to the operation signal S4, and then controls the power source unit (not shown) to start power supply to each unit. In response to this, the light source of the projection unit 13 is turned on.

  In addition, the blower fan 14 is started, and the outside air taken in from the intake port 2 b is blown toward the projection unit 13. At this time, the air volume detection unit 15 detects the air volume W1 in the vicinity of the blower fan 14 and outputs a detection signal S2. The blown outside air flows through the inside of the housing 2a and is discharged from the exhaust port 2c to the outside of the housing 2a. Thereby, the temperature rise inside the housing | casing 2a by the heat | fever which generate | occur | produces from the light source and light modulation element of the projection part 13 is suppressed. In this case, since the outside air is taken in through the air filter 100 attached to the intake port 2b, dust or the like contained in the outside air adheres to the air filter 100 and is removed. For this reason, adhesion of dust to the light source and the light modulation element is prevented.

  Subsequently, the menu button 22 of the remote controller 3 is operated to set conditions and the like for various processes performed by the projector 1. At this time, the remote controller 3 outputs an infrared signal S3 corresponding to the menu button 22, and the light receiving unit 16 outputs an operation signal S4 corresponding to the infrared signal S3 (menu button 22). Next, the control unit 17 instructs the video signal processing unit 11 and the projection unit 13 to project the menu video P2 in accordance with the operation signal S4. In response to this, the video signal processing unit 11 outputs the video data Di for the menu video P2, and the projection unit 13 outputs the projection light L light-modulated based on the video data Di. Thereby, as shown in FIG. 5, the menu image P <b> 2 is projected on the screen 200.

  Next, according to the guidance of the menu video P2, each button of the remote controller 3 is operated to set various processes and conditions. In this case, the projector 1 can arbitrarily set the projection timing of the notification video P4 projected when the air filter 100 is clogged, that is, the condition for projecting the notification video P4, according to the guidance of the menu video P2. It has become. When setting the projection time of the notification image P4, the jog button 23 of the remote controller 3 is operated, and as shown in FIG. Move the cursor to the item “Exchange notification timing” and decide. At this time, the control unit 17 instructs the video signal processing unit 11 and the projection unit 13 to project the setting video P3 in accordance with the operation signal S4. Video P3 is projected. Subsequently, the jog button 23 is operated to move the cursor to an arbitrary projection timing from the five types of projection timings in the setting image P3 as shown in FIG.

  In this case, for example, when the projector 1 is installed in a lobby where many people frequently enter and exit and is operated for a long time, the filter is clogged in a short period of time. For this reason, in such a mode of use, the projection time in the setting image P3 ("level 1" to "level 5" shown in the figure) is earlier (the stage where the degree of clogging is low). (D) “Level 1” at which the projection of the notification video P4 is started is selected. On the other hand, for example, when the projector 1 is used occasionally in a meeting room with little dust, the filter is not easily clogged even if it is used for a long time. “Level 5” at which projection of the notification video P4 is started at a later time (when the degree of clogging becomes high) is selected.

  Next, the control unit 17 specifies the reference value W0 of the air volume that is associated with the selected level in advance based on the operation signal S4 output in response to the selection operation, and causes the storage unit 12 to store it. Thereby, the conditions for projecting the notification video P4 are set. In this case, for example, a configuration is adopted in which the projection time (default projection time) of the notification image P4 in the initial state is set to “level 3” in advance and is changed (reset) only when desired. You can also Subsequently, each button of the remote controller 3 is operated to set conditions and the like for other setting items. Next, when the setting is finished, the menu button 22 of the remote controller 3 is operated again. At this time, the control unit 17 controls the video signal processing unit 11 and the projection unit 13 according to the operation signal S4, thereby terminating the projection of the setting video P3.

  Subsequently, the control unit 17 executes a notification video projection process 50 shown in FIG. In the notification video projection process 50, the control unit 17 specifies the air volume W1 based on the detection signal S2 output from the air volume detector 15 (step 51). Next, the control unit 17 reads the reference value W0 stored in the storage unit 12 and compares it with the air volume W1, and determines whether or not the air volume W1 is equal to or less than the reference value W0 (step 52). In this case, when the air filter 100 is not clogged, since the outside air is sufficiently taken in, the air volume W1 is maintained at a value larger than the reference value W0. Therefore, in this state, the control unit 17 determines in step 52 that the air volume W1 is not less than or equal to the reference value W0, and repeatedly executes steps 51 and 52.

  On the other hand, for example, when projecting the source video P1 based on the video signal S1 from an external device (not shown) such as a DVD player or a personal computer, the connection cable between the external device and the projector 1 is shown in FIG. Then, the external device is activated to start outputting the video signal S1. Subsequently, the video signal processing unit 11 converts the input video signal S1 into video data Di and outputs it. Next, the projection unit 13 outputs the projection light L that is light-modulated based on the video data Di. As a result, the source video P1 is projected on the screen 200 as shown in FIG.

  Next, for example, when the predetermined period has elapsed from the start of use of the projector 1 and the air filter 100 starts to be clogged, intake of outside air is insufficient and the air volume W1 is reduced. In this case, for example, when the air volume W1 becomes a value equal to or less than the reference value W0 (“when the parameter satisfies a predetermined condition” in the present invention), the control unit 17 performs step 52 of the notification video projection processing 50. Then, it is determined whether or not the video signal S1 is in the non-input state, or the input video signal S1 is not compatible with the projection of the video by the projector 1 (projector 1). Is a signal that cannot project an image) (step 53). In this case, when the video signal S1 from the external device is a normal video signal (a signal that allows the projector 1 to project the video), the control unit 17 determines whether or not the notification video P4 is being projected. A determination is made (step 54). In this case, when the notification image P4 is not being projected at this time, the control unit 17 executes Step 51.

  On the other hand, when the output of the video signal S1 (normal video signal) by the external device is stopped, the control unit 17 determines that the video signal S1 is not input in the above-described step 53, and then notifies the user. It is determined whether or not the image P4 is being projected (step 55). In this case, when the notification video P4 is not being projected at this time, the control unit 17 instructs the video signal processing unit 11 and the projection unit 13 to project the notification video P4 (step 56). In response to this, the video signal processing unit 11 outputs the video data Di for the notification video P4, and the projection unit 13 outputs the projection light L light-modulated based on the video data Di. As a result, the notification video P4 is projected on the screen 200 as shown in FIG.

  Next, the control unit 17 executes steps 51 and 52 described above. In this case, when the output of the video signal S1 (normal video signal) by the external device is resumed, this is determined in step 53, and then the above-described step 54 is executed. In this case, since the notification video P4 is being projected at this time, the control unit 17 instructs the video signal processing unit 11 and the projection unit 13 to stop projecting the notification video P4 (step 57). Thereby, the projection of the notification image P4 is stopped. On the other hand, when the notification stop image P4 is being projected in the state where the output stop of the video signal S1 is continued or the input of the video signal S1 which is an unsupported signal is continued, the control unit 17 performs step 53. , 55, and the projection of the notification video P4 is continued (step 58). Therefore, in this state, the projection of the notification video P4 is continued. For this reason, unlike the conventional projector that projects the notification image for a predetermined short time, the projector 1 overlooks the notification image and over time the air filter 100 is cleaned or replaced, thereby causing a failure. It is possible to reliably prevent such a situation.

  Next, when the user cleans or replaces the air filter 100 by knowing that cleaning or replacement is necessary by projecting the notification image P4, the air volume W1 becomes a value larger than the reference value W0. At this time, the control unit 17 determines that in step 52 described above, and repeatedly executes steps 51 and 52. Thereafter, the control unit 17 executes each step in the notification image projection processing 50, whereby the notification image P4 is projected and stopped in accordance with the clogged state of the air filter 100. In this case, the projector 1 can arbitrarily set the conditions for projecting the notification video P4 according to the usage pattern. For this reason, it is possible for the user who has made the setting to reliably recognize the exact time when the user should actually perform cleaning or replacement.

  Thus, according to the projector 1 and the notification image projection method, the condition for projecting the notification image P4 related to the clogged state of the air filter 100 is set by an operation using the remote controller 3, and the set condition is satisfied. By projecting the notification video P4 at the time, for example, conditions are set so that the notification video P4 is projected earlier in the usage mode that is likely to be clogged, and the notification video P4 is projected in the usage mode that is less likely to be clogged. The user can arbitrarily set the conditions according to the usage mode of the projector 1 such as setting the conditions so that the image is projected later. Therefore, according to the projector 1 and the notification image projection method, the user who has made the settings can surely recognize the exact time when the air filter 100 should be actually cleaned or replaced. Compared with the conventional electronic device in which information related to clogging is notified when one fixed condition is satisfied, the function for notifying information related to the clogging state of the filter can be used sufficiently effectively. it can.

  Further, according to the projector 1 and the notification image projection method, the notification image P4 that can notify the information related to the clogging state of the air filter 100 is projected, for example, the LED is turned on or clogged by voice guidance. Compared with the method of notifying the information regarding the clogging state, the clogging state can be more reliably notified to the user.

  Further, according to the projector 1, the notification video P4 is continuously displayed when the video signal S1 is not input and when the input video signal S1 is an unsupported signal that does not correspond to the projection of the video by the projector 1. Unlike conventional projectors that project a notification image for a predetermined short period of time by projecting, the time for cleaning or replacing the air filter 100 is overlooked due to oversight of the notification image, which causes a failure. Can be reliably prevented.

  In addition, this invention is not limited to said structure. For example, although the example applied to the projector 1 as an example of the electronic device has been described above, it may be applied to an electronic device that includes a display unit such as an LCD, a plasma display, and a CRT and displays the notification video P4 on the display unit. it can. Moreover, it can also be applied to an electronic device that is provided with a notification unit other than a video display such as an audio output unit or an LED and outputs caudal sound or notifies clogging information by turning on the LED. Further, the example in which the condition is set by selecting one of a plurality of projection times (levels) in the setting image P3 has been described above. For example, the reference value W0 is set by operating the numeric buttons of the remote controller 3. A configuration in which conditions are set by inputting numerical values can also be adopted. Further, the condition is not limited to the remote controller 3, and the above condition can be set by operating an operation unit provided in the main body 2 (housing 2a).

  In addition, the configuration example in which the air volume detection unit 15 is provided to detect the air volume W1 as a parameter capable of specifying the clogging of the air filter 100 has been described above, but the configuration is not limited thereto. For example, a detection unit that detects a voltage or current (another example of a parameter in the present invention) supplied to the blower fan 14 or a transmission amount of inspection light irradiated on the air filter 100 (a further example of the parameter in the present invention) The structure provided with the detection part which detects this can be employ | adopted. In this case, when each of these configurations is adopted, the same effect as described above can be obtained by arbitrarily setting the unit and value of the reference value W0 using the remote controller 3 in accordance with the parameters detected by each detection unit. Can be realized. In addition, the menu video P2, the setting video P3, and the notification video P4 described above are examples, and it is a matter of course that the contents of these videos P2 to P4 can be arbitrarily defined.

A projector comprising: a detection unit that detects; and a control unit that causes the projection unit to project a notification image capable of reporting information related to the clogged state when the parameter satisfies a predetermined condition,
The control unit is configured such that when the parameter satisfies the predetermined condition and the video signal is not input or the input video signal is an unsupported signal that does not correspond to the projection of the image by the projector. A projector that continuously projects notification images. Information related to the clogging state is notified when a parameter that can specify the clogging state of the filter disposed in the outside air intake opening formed in the housing of the projector satisfies a predetermined condition. A notification image projection method for projecting a possible notification image on a projection unit disposed in the casing,
A notification image projection method for projecting the notification image when the parameter satisfies the predetermined condition set by a setting operation using an operation unit.
