(Embodiment 1)
As shown in FIGS. 1 to 5, a humidifying means 2 is disposed at the center of the upper part of the outer contour of the image monitor apparatus main body 1 for displaying an image. The humidifying means 2 is provided with humidified water inside a hollow humidifier outer shell 3. Humidifying tank 4, an ultrasonic vibration element 5 for immersing the humidified water stored in humidifying tank 4 to vaporize the humidifying water, and humidifying water humidified by the ultrasonic vibration element 5. And a control means 7 for controlling the operation of the ultrasonic vibration element 5 and the blower 6. Further, one end of the humidifier shell 3 has an intake opening 8 for introducing the air blown by the blower 6 into the humidifier shell 3 and the other end of the humidifier shell 3 facing the intake opening 8 is humidified. A blower opening 9 for releasing the generated air to the outside of the humidifier shell 3 is opened toward the image monitor user. Humidification water is supplied to the humidification tank 4 by a water supply tank 10 that is detachably provided from the outside of the humidifier shell 3 and stores the humidification water therein. A humidifying water detecting means 11 for detecting the presence or absence of the humidifying water is disposed inside the humidifying tank 4. The humidified water detecting means 11 includes a float 12 having buoyancy with respect to the humidified water, a float shaft 13 that pivotally attaches the float 12 to a specified position inside the humidifying tank 4, and a magnet embedded in the float 12. 14 and a reed switch 15 fixed to the wall surface of the humidifying tank 4 where the contact is closed by the magnetic force of the magnet 14, and the state where the contact of the reed switch 15 is closed is the water-filled state. The presence or absence of humidified water is transmitted to the control means 7 by outputting to the control means 7. Further, the rotational position is output to the control means 7 in the form of an electric signal at a position where the image monitor user can operate by bringing the humidifying means 2 close to the air blowing opening 9 facing the image monitor user and adjusting the wind speed A wind speed adjusting volume 16 for transmitting the state to the control means 7 is arranged. Further, a fixed convex portion 17 for detachably attaching the humidifier shell 3 to the image monitor device main body 1 is fixed at a position of the humidifier shell 3 in contact with the upper portion of the image monitor device main body 1. In FIG. 3, thick arrow lines indicate the flow of wind by the air blow.

  Here, the blower opening 9 provided at one end of the humidifier shell 3 winds in a direction substantially perpendicular to the image display surface of the image monitor apparatus main body 1 with the humidifying means 2 attached to the image monitor apparatus main body 1. It was established so as to blow out air so that air can be blown in the range of the face size with the eyes of the image monitor user at the general interval between the image monitor user who looks at the image monitor and the image monitor apparatus main body 1. Is set.

  Here, the water supply tank 10 is configured to be inserted and disposed so that the opening provided at the lower end is immersed in the surface of the humidified water accumulated in the humidifying tank 4, and the surface of the humidified water is used for the progress of the humidifying operation. When the pressure decreases and a gap is generated between the opening of the water supply tank 10 and the water surface, air enters the inside of the water supply tank 10 until the gap between the opening and the water surface is eliminated. 10 is configured by a general automatic water supply system in which humidified water is supplied to the humidifying tank 4.

  Here, the ultrasonic vibration element 5 uses a so-called piezoelectric ceramic vibrator such as PZT which generates ultrasonic vibration when a high frequency voltage is applied, and the humidified water is finely introduced into the air by the fine ultrasonic vibration. The element having a resonance frequency of about 1.6 kHz suitable for vaporization by the fine dispersion of the humidified water is used.

  Here, the blower 6 uses a general electric motor that generates rotational power when a DC or AC voltage is applied.

  The control means 7 includes a microcomputer 18 that controls the operation of the entire humidifier, a high-frequency voltage generation circuit 19 that is controlled by the microcomputer 18 and drives the ultrasonic vibration element 5, and a blower drive circuit that also drives the blower 6. 20 and a microcomputer 18, a high-frequency voltage generation circuit 19, and a power supply circuit 21 that supplies power to the blower drive circuit 20.

  Here, the microcomputer 18 is a so-called single chip having a central processing unit (CPU), an input / output device, an analog / digital conversion input device (A / D), a read only memory (ROM), and a read / write memory (RAM). When a microcomputer is used and an electric signal of the contact point of the reed switch 15 output from the humidified water detecting means 11 is received as an input, the presence of the humidified water in the humidifying tank 4 is determined. In the state where the presence of humidified water is determined, an operating voltage signal is output to the high-frequency voltage generation circuit 19 and the blower drive circuit 20 to drive the ultrasonic vibration element 5 and the blower 6 to humidify the air. To implement. Further, the microcomputer 18 receives the electrical signal from the wind speed adjustment volume 16 that converts the rotation position into an electrical signal and outputs the change in the voltage value, and drives the blower device based on the voltage value of the electrical signal from the wind speed adjustment volume 16. Software is programmed to change the operating voltage signal of the circuit 20 to change the rotational speed of the blower 6.

  Here, the high-frequency voltage generation circuit 19 is configured by a general self-excited oscillation circuit that converts the power of the power supply circuit 21 to generate a high-frequency voltage having a resonance frequency of the piezoelectric ceramic vibrator constituting the ultrasonic vibration element 5. It is.

  Here, the blower drive circuit 20 is configured mainly with a general switch element such as a transistor that enables the power of the power supply circuit 21 to be turned on and off with respect to the blower 6.

  Next, based on FIG. 6, the microcomputer 18, which is the main body of the control means 7, operates the operation voltage signal of the blower drive circuit 20 that controls the voltage value variably set by the wind speed adjusting volume 16 and the blower. A change in the rotation speed of the device 6 will be described. FIG. 6 shows the relationship between the voltage value variably set by the wind speed adjustment volume 16 input to the microcomputer 18 and the change in the operating voltage signal of the blower drive circuit 20 that the microcomputer 18 determines based on the input voltage value. And a graph showing the relationship between the rotational speeds of the blower 6, the horizontal axis indicates the voltage value input to the microcomputer 18 variably set by the wind speed adjustment volume 16, and the vertical axis indicates the fan drive circuit 20. The operating voltage signal and the rotational speed of the blower 6 are shown. In the present driving method, as shown in the figure, the rotational speed of the blower 6 is controlled by so-called PWM control that narrows the application interval of the operating voltage signal of the blower drive circuit 20 as the voltage value variably set by the wind speed adjustment volume 16 increases. It is controlled to increase. When the voltage value variably set by the wind speed adjustment volume 16 is the lowest potential value, the operation voltage signal of the blower drive circuit 20 is also stopped to completely cut off the power supply from the power supply circuit 21 to the blower 6 and rotate it. When the voltage value variably set by the wind speed adjustment volume 16 is the maximum potential value, the operating voltage signal of the blower drive circuit 20 is always applied and the power supply circuit 21 to the blower 6 is stopped. The operation of the microcomputer 18 is set in a software manner so that the rotation speed is maximized and the air is blown at the maximum wind speed.

  Next, the operation of the humidifying means 2 configured as described above will be described. In the state where the humidifying means 2 is attached to the upper portion of the outer shell of the image monitor device 1 by the fixed convex portion 17 fixed to the humidifier shell 3, the humidifying water is supplied to the humidifying tank 4 inside the humidifier shell 3. When the stored water supply tank 10 is inserted, humidified water is supplied from the water supply tank 10 to the humidifying tank 4. When humidified water is supplied to the humidifying tank 4, as the water level inside the humidifying tank 4 rises, the float 12 that constitutes the humidified water detecting means 11 rotates around the float shaft 13 on which the float 12 is attached. As the float 12 floats, the reed switch 15 is closed by the magnetic force of the magnet 14 when the magnet 14 built in the float 12 approaches the reed switch 15 fixed on the wall surface of the humidifying tank 4. The presence state of the humidified water in the humidifying tank 4 is output in the form of an electrical signal from the humidifying water detecting means 11 to the computer 18, and the microcomputer 18 receives the output and the presence state of the humidified water in the humidifying tank 4. Judging. When the microcomputer 18 determines the presence of the humidified water in the humidifying tank 4, it supplies power from the power supply circuit 21 to the ultrasonic vibration element 5 and the blower 6 via the high-frequency voltage generation circuit 19 and the blower drive circuit 20. To start. When the ultrasonic vibration element 5 is activated, the ultrasonic vibration element 5 generates ultrasonic vibration. Due to this ultrasonic vibration, the humidified water in the humidifying tank 4 is finely dispersed in the air and dispersed inside the humidifier shell 3. When the air in the space is humidified and the blower 6 is activated, the outside air is introduced into the humidifier shell 3 from the intake opening 8 provided at one end of the humidifier shell 3 and is humidified inside the humidifier shell 3. The air is pushed out in the direction of the blower opening 9 provided at one end of the humidifier shell 3 opposite to the intake opening 8, so that the humidified air from the blower opening 9 is blown.

  Here, the blower opening 9 blows air in a range of the size of the face around the eyes of the image monitor user who uses the image monitor device main body 1 with the humidifying means 2 attached to the image monitor device main body 1. Therefore, the humidified air blown from the blower opening 9 is blown toward the face centered on the eyes of the image monitor user.

  Further, a voltage value variably set by the wind speed adjusting volume 16 is input to the microcomputer 18 constituting the control means 7 when the image monitor user operates the wind speed adjusting volume 16 disposed close to the air blowing opening 9. The microcomputer 18 changes the supply voltage from the power supply circuit 21 to the blower 6 by changing the application interval of the operating voltage signal of the blower drive circuit 20 according to the input voltage value. Since the rotation speed changes, the humidified air blown from the blower opening 9 can be changed to the blower air speed desired by the image monitor user.

  Here, a configuration is shown in which the humidifying means 2 is attached to the upper part of the outer shell of the image monitor device 1 by a fixed projection 17 fixed to the outer shell 3 of the humidifier, but is directly attached to the image monitor device 1. Needless to say, even if the humidifying means 2 is built in, there is no difference in its function and effect.

  Here, the fixed projection 17 for attaching the humidifying means 2 to the upper part of the outer shell of the image monitor device 1 is shown as being fixed to the humidifier shell 3, but it is movable with respect to the humidifier shell 3. By using a configuration that is fixed to the image monitor device 1, it is possible to further improve the utility such as position adjustment at the time of being attached to the image monitor device 1 and use of the humidifying means 2 attached to the image monitor device 1 of various sizes.

  Here, a configuration is shown in which the humidifying means 2 is attached to the upper part of the outer shell of the image monitor device 1 by a fixed convex portion 17 fixed to the humidifier shell 3, but it is adjacent to the image monitor device 1. Needless to say, the same effect can be realized by separately arranging the humidifier and blowing the humidified air from the humidifier toward the eyes of the image monitor user.

  In addition, since the humidified air blown from the blower opening 9 is blown to the range of the face centering on the direction of the eyes of the image monitor user, it naturally reduces the drying of the eyes of the image monitor user. Needless to say, drying of facial skin can also be effectively alleviated.

  In addition, it goes without saying that the relaxation feeling of the image monitor user can be improved by adding perfume that brings a sense of rest to humidified water or humidified air, or adding negative ions generated by a negative ion generator. .

  Further, as shown in FIG. 7, in conjunction with the operation of the wind speed adjustment volume 16, the power supply from the power supply circuit 21 to the ultrasonic vibration element 5 is changed by the microcomputer 18 and the drive time of the operating voltage signal of the high-frequency voltage generation circuit 19 is changed. By configuring as software, it is possible to adjust the amount of humidification that is linked to the change in the humidified blast speed according to the operation of the wind speed adjustment volume 16 by the adjustment of the image monitor user. FIG. 7 shows the voltage value variably set by the wind speed adjustment volume 16 input to the microcomputer 18 and the state of the operating voltage signal of the high-frequency voltage generation circuit 19 that the microcomputer 18 determines based on the input voltage value. Further, the graph shows the relationship of the power application state to the ultrasonic vibration element 5, the horizontal axis shows the voltage value variably set by the wind speed adjustment volume 16, and the vertical axis shows the operating voltage signal of the high frequency voltage generation circuit 19 and the ultrasonic wave. The state of power application to the vibration element 5 is shown. In the present driving method, as shown in the figure, as the voltage value variably set by the wind speed adjustment volume 16 becomes higher, power application to the ultrasonic vibration element 5 is performed by so-called PWM control that narrows the driving time interval of the high-frequency voltage generation circuit 19. It is controlled to increase the amount of humidification by increasing the time average.

  Here, the relationship between the blast air volume and the humidification amount that are variably set is an excessively humid state where condensation occurs in the ambient temperature and humidity range determined by the product specifications of the target device, that is, the air is blown from the air blowing opening 9. The humidity is adjusted based on the principle that the amount of humidification is changed so that the absolute humidity in the humidified air does not exceed the saturated water pressure in the ambient temperature range. For example, if the ambient temperature is 25 ° C, Basically, the humidification amount is adjusted so that the humidity value is 23.1 g / m 3 or less. However, in actuality, since there is dispersion of humidified air blown from the blower opening 9 and calculation is difficult to determine, a humidification amount that does not cause condensation on the blown air volume experimentally according to the ambient temperature and humidity range is obtained. This relationship is defined by software in the microcomputer 18 and the amount of humidification generated is controlled.

  The voltage value variably set by the wind speed adjusting volume 16 determined by the microcomputer 18 is from the lowest potential value to the voltage value specified (in FIG. 7, between the voltages V0 and V1), and the high frequency voltage generating circuit. By configuring the software of the microcomputer 18 so as to generate a minimum amount of humidification defined by driving 19 at a predetermined longest time interval and minimizing the application of power to the ultrasonic vibration element 5, the minimum It is also possible to set to ensure a limited amount of humidification. Here, the voltage value stipulated from the minimum potential value variably set by the wind speed adjustment volume 16 determined by the microcomputer 18 is a low speed stipulated from the state in which the rotation of the blower 6 is stopped when the humidifying means 2 is used. The humidification amount that does not cause an excessive humidification state even in the state is experimentally obtained and set. Therefore, in conjunction with the image monitor user operating the wind speed adjustment volume 16 to change the humidified air blown from the blower opening 9 to the blower wind speed desired by the image monitor user himself, The prescribed minimum humidification amount can be maintained while suppressing the occurrence of excessive humidification during the constant air blowing speed defined by.

  Further, as shown in FIGS. 8 to 10, the distance between the humidifying means 2 and the image monitor user is measured by bringing the humidifier outer shell 3 of the humidifying means 2 close to the air blowing opening 9 facing the image monitor user. The distance information measured by the distance measuring means 22 in software by the microcomputer 18 constituting the main body of the control means 7 by providing the distance measuring means 22 for outputting the measured distance information to the control means 7. Based on this, the operation voltage signal application interval of the blower drive circuit 20 is changed to change the power supplied from the power supply circuit 21 to the blower 6, thereby changing the rotational speed of the blower 6 and blowing air from the blower opening 9. The image monitor user himself / herself can automatically adjust the wind speed of the humidified air instead of operating the wind speed adjustment volume 16.

  Here, the distance measuring unit 22 receives the transmission of the ultrasonic wave to the distance measurement target and the reflected wave from the transmitted ultrasonic target, and the distance from the distance measurement target as the time difference between the transmission of the ultrasonic wave and the reception of the reflected wave. This is realized by a general ultrasonic reflection type distance measuring method for recognizing the image, and the image monitor user is arranged so that the ultrasonic transmission element 23 and the ultrasonic reception element 24 are centered on the center of the ultrasonic transmission / reception range. The time difference between the ultrasonic transmission of the ultrasonic transmission element 23 and the reflected wave reception of the ultrasonic reception element 24 is arranged as shown in FIG. 18 (td in the figure), the microcomputer 18 determines the distance from the image monitor user by converting the distance from this time difference based on the atmospheric sound velocity. One in which the.

  Next, based on the distance information measured by the distance measuring means 22 based on FIG. 12, the software is calculated from the distance to the image monitor user determined by the microcomputer 18 constituting the main body of the control means 7 and the determined distance to the image monitor user. The operation voltage signal of the blower drive circuit 20 controlled in terms of wear and the change in the rotational speed of the blower 6 will be described. FIG. 12 is a graph showing the relationship between the distance to the image monitor user determined by the microcomputer 18 and the change in the operating voltage signal of the blower drive circuit 20, and the relationship between the rotational speed of the blower 6 and the horizontal axis. The operation voltage signal of the blower drive circuit 20 and the rotational speed of the blower 6 are shown on the vertical axis of the distance to the determined image monitor user. As shown in the figure, the rotational speed of the blower 6 is increased by so-called PWM control that narrows the application interval of the operating voltage signal of the blower drive circuit 20 that is separated from the image monitor user determined by the microcomputer 18. It is something to control.

  It should be noted that the relationship between the air blowing speed of the humidified air corresponding to the distance from the image monitor user determined by the microcomputer 18 is that the image monitor user using the image monitor device is away from the humidifying means 2 at a position away from the image monitor device. It is set based on changing the blowing air speed so that the air speed is such that it does not feel uncomfortable even when it receives humidified air. For example, the target image monitor device is an image display device of a personal computer. In this case, the optimum distance between the image monitor device and the image monitor user is 50 to 80 cm, and the shortest distance is about 30 cm. It is set to judge the distance in the range of about 25cm to 90cm, and humans feel comfortable and strange Since the wind speed that is difficult to feel is generally around 1 m / sec, even if the distance between the humidifying means 2 and the image monitor user changes between the above-mentioned judgment distances, the image monitor user's The rotational speed of the blower 6 is varied and controlled so that the wind speed felt at the position is about 0.5 m / sec to 1 m / sec.

  Further, as shown in FIGS. 13 and 14, the temperature / humidity display means 25 is provided at a position visible from the image monitor user of the humidifier shell 3 of the humidifying means 2 to use the image monitor device for the image monitor user. It is also possible to recognize the necessity of humidification by recognizing the value of ambient temperature and humidity. The temperature / humidity display means 25 measures the temperature / humidity of the ambient air around the humidifying means 2 with the humidity measuring means 27 and the temperature measuring means 28 through a sensor opening 26 opened outside the humidifying means 2. The temperature / humidity information measured by the measuring means 28 is read by the microcomputer 18 constituting the main body of the control means 7, and the temperature / humidity information read by the microcomputer 18 is read from the microcomputer 18 to the display means 29 by the display means 29. The display unit 29 is configured to display the temperature and humidity state of the surrounding air by converting the signal form to the display method and outputting it.

  Here, the humidity measuring means 27 is a general relative humidity measuring circuit using a humidity sensor whose impedance value changes according to the value of relative humidity and an impedance voltage conversion circuit which converts the impedance value of the humidity sensor into a change in voltage value. It is composed.

  Here, the temperature measuring means 28 is a general thermistor type temperature in which a thermistor whose resistance value changes with temperature and a resistance connected in series with the thermistor to convert the change in the voltage dividing resistance ratio into a change in voltage. It consists of a measurement circuit.

  Here, the display means 29 uses a numerical display such as a general segment lighting type LED to display numerical values, and lights up each segment corresponding to the numerical data of humidity and temperature determined from the microcomputer 18. The display is switched and displayed.

  Further, as shown in FIGS. 15 to 17, the control means 7 is provided with a drying alarm means 30 for informing the image monitor user of the dry state by lighting of light at a position visible to the image monitor user of the humidifying means 2. By comparing the humidity information measured by the humidity measuring means 27 read by the microcomputer 18 constituting the main body with the reference humidity value specified in advance by the microcomputer 18, the measured humidity value becomes the reference humidity value. On the other hand, if the drying alarm means 30 is controlled to be turned on by the microcomputer 18 if it is in the drying direction, the image monitor user can be directly notified of the dry state.

  Here, the dry alarm means 30 is composed of a light emitting component such as a general LED.

  Further, as shown in FIG. 18, the image confirmation user 31 is provided with the image confirmation device 31 at a position visible from the image monitor user of the humidifier shell 3 of the humidification device 2, and the image confirmation device is using the image monitor device. By configuring so that the appearance of himself / herself reflected in the image 31 can be visually confirmed, the image monitor user directly relates to the dryness such as redness of the eyeball and rough skin from the appearance of himself / herself reflected in the image confirmation means 31. By making it easier to check the symptoms, it is possible to assist the image monitor user in recognizing the necessity of humidification at that time, and to provide a function that makes it easy to check the effect of humidification.

  Here, it is optimal that the figure confirmation means 31 is configured by arranging a mirror, and the image monitor user is located at a general interval between the image monitor apparatus main body 1 and the image monitor user to which the humidifying means 2 is to be installed. However, a mirror having a minimum area that can visually check the condition of the eyes and skin of the user of the image monitor is arranged. Further, by enlarging the appearance of the mirror by arranging the mirror disposed here as a concave mirror, it is possible to make it easier for the image monitor user to observe, for example, the state of the eye to be confirmed.

  Further, as shown in FIG. 19 to FIG. 21, in place of the figure confirmation means 31, an image input for photographing the direction of the image monitor user and displaying the photographed image on the image monitor device viewed by the image monitor user. By arranging the means 32, the image monitor user can visually confirm the appearance of the image monitor user himself / herself, which is photographed by the image input means 32 and reflected in the image monitor apparatus main body 1a while using the image monitor apparatus. By doing so, it is possible to make it easier for the image monitor user to confirm specific symptoms related to dryness such as redness of his own eyeball and rough skin. Here, the image monitor apparatus main body 1a is described based on the case where it is an image display apparatus of a personal computer. In the figure, the image monitor apparatus main body 1a provided with the humidifying means 2 is the main body of the personal computer. Configuration of a general personal computer that is connected to the image output output terminal 34 of the computer apparatus main body 33 and displays an image signal output from the image output terminal 34 corresponding to the processing result of the computer apparatus main body 33 on the image monitor apparatus main body 1a. The image input means 32 is connected to the USB terminal 35 of the computer apparatus main body 33, and the video signal photographed by the image input means 32 and converted into an electrical signal is taken into the computer apparatus main body 33 via the USB terminal 35. The captured video signal is sent to the computer device body 33. The image captured by the image input means 32 is converted into an image signal output from the image output output terminal 34 by the software processing of the image and output from the image output output terminal 34 to the image monitor main body 1a. It is configured to be displayed on the monitor device main body 1a.

  Here, the image input means 32 forms an image of light from the object to be photographed on an image sensor device such as a CCD or CMOS via an optical lens, converts the image into a voltage signal, and converts the voltage signal into an A / D converter. Is converted into a digital signal, and the digital signal is converted into a communication signal conforming to a USB (Universal Serial Bus) data communication standard via a USB interface, whereby the video signal at the USB terminal 35 of the computer device body 33 is converted. The computer is composed of a USB camera which can be read and processed by the computer main body 33.

  Note that when the target of the image monitor device is a general television, the voltage signal obtained by causing the image input means 32 to image light from the subject to be imaged on an image sensor device such as a CCD or CMOS through an optical lens. A configuration that allows input to each video signal input terminal of a television receiver via an NTSC interface that changes to a video signal (composite signal or separate signal) conforming to NTSC (National Television Standard Committee) capable of television reception. Needless to say, similar actions and effects can be realized.

  Furthermore, as shown in FIG. 22 and FIG. 23, the image monitor user can arrange the illumination means 36 that illuminates the direction of the image monitor user at a position visible from the image monitor user of the humidifier shell 3 of the humidifying means 2. It is also possible to add a function of brightly illuminating the image monitor user with the illumination means 36 in a state where the image monitor device is used. Therefore, for example, in a configuration in which the humidification means 2 is provided with the figure confirmation means 31 as shown in FIG. 22, the figure of the image monitor user illuminated by the illumination means 36 reflected on the figure confirmation means 31 becomes bright and clear, and thus the image It becomes easier for the monitor user to confirm his / her own appearance reflected in the appearance confirmation means 31, and the specific symptoms related to dryness such as redness of the eyeball and rough skin can be confirmed in detail from the appearance. It is possible to recognize the necessity of humidification at the time, and to provide a function that makes it easier to confirm the effect of humidification in a state where humidification by the humidifying means 2 is being performed.

  Here, as shown in the figure, the illumination means 36 includes an illumination LED 37 that constitutes the main body of illumination, and the illumination means 36 at a position that can be seen by the image monitor user of the humidifying means 2 so that the image monitor user can switch the illumination on and off. An off switch 38 is arranged, and the state in which the illumination on / off switch 38 is switched is read by the microcomputer 18 constituting the main body of the control means 7, and the illumination on / off switch 38 read by the microcomputer 18 is switched from the switched state. The microcomputer 18 determines whether the illumination LED 37 is turned on or off, and is controlled by software so that the power supply from the power supply circuit 21 to the illumination LED 37 is turned on and off.

  Here, the illumination on / off switch 38 is configured by a general contact opening / closing type switch that transmits the closed state of the contact as an illumination lighting instruction state to the microcomputer 18 in the form of an electrical signal.

  Thus, in the configuration in which the illumination means 36 for illuminating the direction of the image monitor user is arranged at a position visible from the image monitor user of the humidifier shell 3 of the humidification means 2, the image monitor user feels the necessity of illumination and performs illumination. When the on / off switch 38 is operated in the lighting direction, the contact of the illumination on / off switch 38 is closed, and the closed state is transmitted to the microcomputer 18 constituting the main body of the control means 7 in the form of an electrical signal. When the microcomputer 18 determines that the illumination LED 37 is turned on and supplies power to the illumination LED 37 from the power supply circuit 21, the illumination LED 37 is turned on, and the illumination LED 37 is turned on. As a result, the image monitor user is brightly illuminated.

  Needless to say, in the configuration in which the illumination unit 36 is arranged in the humidifying unit 2, there is no difference in the operation and effect even in the configuration in which the image input unit 32 confirms the image using the image monitor device instead of the image confirmation unit 31.

  Further, as shown in FIG. 24, an illumination outer case 37a that holds the LED 37 for illumination inside, and an illumination for attaching the illumination outer case 37a to the humidifier outer case 3 in a state in which it can be rotated in the vertical direction. An image of the center of the direction in which the illumination LED 37 illuminates is provided by providing the means rotation shaft 39 so that the illumination outline 37a can be rotated up and down at the position held by the humidifier outline 3 around the illumination means rotation axis 39. The monitor user can also change the setting. Therefore, in the configuration in which the humidifying means 2 is provided with the appearance confirmation means 31 and the image input means 32 so that the appearance of the image monitor user himself / herself can be confirmed, the illumination LED 37 is in a state where the image monitor user is using the image monitor device. It is possible to provide a function capable of adjusting the center of the illuminating direction so that the image monitor user can illuminate the portion most desired to be confirmed most brightly. In FIG. 24, a thick arrow line indicates a general movable range of the illumination outline 37a with respect to the humidifier outline 3.

  Here, the angle at which the illumination outer shell 37a can be rotated in the vertical direction at the position held by the humidifier outer shell 3 is the distance between the image monitor apparatus main body 1 and the image monitor user that is the installation target of the humidifying means 2. For example, when the target image monitor device is an image display device of a personal computer, the distance between the image monitor device and the image monitor user is generally about 50 cm to 80 cm. Therefore, the vertical distance of the face with a minimum distance of 40 cm so that the moving range of the center of the optical axis of the illumination moves within the range of 23 cm to 25 cm, which is the average vertical length of a human face, at this distance. Is defined as 26 cm and is set to an angle of about 36 °.

  Further, as shown in FIG. 25 to FIG. 27, the range of the humidified air flow can be obtained by disposing the air blowing range changing means 40 in the air blowing opening 9 for releasing the air humidified by the humidifying means 2 to the outside of the humidifier shell 3. It is also possible for the image monitor user to change and adjust the spread.

  The air blowing range changing means 40 arranges the air blowing louver 41 on the lower surface of the front end of the air blowing opening 9, and the air blowing louver 41 is louvered with respect to the humidifier shell 3 so that the opening area of the air blowing opening 9 in the air blowing direction is widened. It is engaged so as to be rotatable about the rotation shaft 42, and the image monitor user himself operates the fan opening louver 41 to rotate with respect to the louver rotation shaft 42, so that The opening area in the direction can be adjusted. As shown in FIG. 26, when the blowing opening louver 41 is rotated in a direction in which the area of the blowing opening 9 in the blowing direction of the blowing opening 9 is reduced with respect to the louver rotation shaft 42, the blowing is performed. The humidified air blown out from the opening 9 is mainly concentrated in the range of the eyes of the image monitor user, and as shown in FIG. Experimentally confirm that the air blow is directed to a wide range of the entire face of the image monitor user when the louver rotation shaft 42 is rotated in a direction in which the area of the air blowing opening 9 in the air blowing direction increases. The opening area when moving is set and configured. In FIG. 26 and FIG. 27, the thick arrow line indicates the flow of the wind by the air blowing.

  Here, the opening angle of the blower opening louver 41 with the louver rotating shaft 42 as the center is determined by the airflow opening 9 in the interval distance between the image monitor apparatus main body 1 to which the humidifying means 2 is installed and the image monitor user. It is set so that the humidified air blown from can be changed to a blow that covers the entire face of the image monitor user from the case of blowing in a state of being concentrated and concentrated in the direction of the eyes of the image monitor user, For example, when the target image monitor device is an image display device of a personal computer, the distance between the image monitor device and the image monitor user is generally about 50 cm to 80 cm. A minimum spacing of 40 cm to allow airflow to cover the average longitudinal length of the face, ranging from 23 cm to 25 cm. Is for setting the opening angle of approximately 36 ° to define direction length a and 26cm.

  As described above, in the configuration in which the air blowing range changing means 40 is arranged in the air blowing opening 9 of the humidifying means 2, when the image monitor user himself wants to change the expansion of the humidifying air blowing range to the air blowing concentrated in his own eye range, the air blowing opening. The louver 41 is adjusted by rotating the louver 41 in a direction in which the area of the air blowing opening 9 in the air blowing direction becomes narrower with respect to the louver rotating shaft 42, and the image monitor user himself widens the range of the humidified air blowing over the entire face. When it is desired to change the air flow to a range, the image monitor user himself desires by rotating the air opening louver 41 in the direction in which the area of the air blowing direction of the air opening 9 is increased with respect to the louver rotation shaft 42. The function which can humidify the humidification object to perform more appropriately can be provided.

  Further, as shown in FIGS. 28 and 29, a part of the air path of the humidified air that is sucked from the intake opening 8 by the blower 6 and blown toward the blower opening 9 inside the humidifier shell 3 of the humidifying means 2 is partially blocked. A Peltier element 43 that generates a heat drop between two opposing faces by applying a direct current to a position that bisects, generates heat on one side and generates a temperature drop on the other side, A cooling surface 45 of the Peltier element 43 is formed by opening an exhaust opening 44 for exhausting blown air to the humidifier casing 3 close to the intake opening 8 in the air passage in the humidifier casing 3 divided by the Peltier element 43. An air passage that is arranged with the side facing the exhaust opening 44 and blows air around the humidifying means 2 that is sucked into the inside of the humidifier shell 3 from the intake opening 8 by the blower 6 toward the blower opening 9. And an air passage that blows air toward the exhaust opening 44 The air contained in the outside air is divided into two paths and exhausted from the exhaust opening 44 along the cooling surface 45 side of the Peltier element 43 while the air in the air path that is blown toward the one exhaust opening 44 is exhausted. The moisture is cooled by the cooling surface 45 of the Peltier element 43, condensed and condensed to change into water droplets and dripped into the humidifying tank 4, so that humidified water is replenished so that the outside of the image monitor user can be supplied. It is also possible to dispense with water supply. In FIG. 28, the thick arrow line indicates the flow of wind by the air blowing.

  Here, the ultrasonic vibration element 5 disposed at a position to be immersed in the humidified water accumulated in the humidifying tank 4 for vaporizing the humidified water is located on the side of the air opening 9 separated by the Peltier element 43 inside the humidifier shell 3. The air humidified with the humidified water vaporized by the ultrasonic vibration element 5 by being disposed below the air passage is blown out from the air blowing opening 9 along the flow of the air flowing through the air passage on the air blowing opening 9 side. It becomes.

  Here, a heat sink 46 is attached to each surface where heat generation and a temperature drop of the Peltier element 43 occur to enhance the heat dissipation effect, so that heat is efficiently transferred to the surrounding air. Further, the air flow rate on the air passage side that blows out toward the air opening 9 is smaller than the air flow rate on the air passage side that blows out the air flow passage in the humidifier shell 3 divided by the Peltier element 43 toward the exhaust opening 44. The flow of the air blown toward the blower opening 9 is configured so that the air is blown through a gap formed between the lower end of the Peltier element 43 and the surface of the humidified water accumulated in the humidifying tank 4. The amount of humidified water supplied by cooling and condensing the air in the air path that is blown toward the exhaust opening 44 by the cooling surface 45 of the Peltier element 43 is substantially balanced with the amount of reduced water consumed by the humidification. In addition, the air velocity of the humidified air blown from the air blowing opening 9 is examined experimentally together with the air flow setting of the air blower 6 so that the air velocity of the humidified air does not give a sense of incongruity to the image monitor user. It is to determine the width of the gap formed between the water surface of the humidifying water that has accumulated to the lower end of the Peltier element 43 to the humidifying tank 4. The Peltier element 43 is an element that generates a heat drop between two opposing faces by applying a direct current due to a thermoelectric effect, generates heat on one face, and a temperature drop on the other face. The magnitude of the heat drop that occurs between the faces can be changed by adjusting the amount of direct current applied, and the amount of heat drop increases as the amount of current increases. Therefore, here, the power supplied to the Peltier element 43 is configured to be controlled by the control means 7, and the power supply circuit 21 energizes the Peltier element 43 by the microcomputer 18 constituting the main body of the control means 7. By adjusting the operating voltage signal of the Peltier drive circuit 47 that changes the state, the power supplied to the Peltier element 43 from the power supply circuit 21 is adjusted, and the amount of current flowing through the Peltier element 43 is reduced by the target temperature drop. It is controlled by software so that it occurs.

  Here, the target value of the temperature drop of the Peltier element 43 is blown toward the exhaust opening 44 at the stage where the air in the air passage blown toward the exhaust opening 44 is cooled and condensed by the cooling surface 45 of the Peltier element 43. Experimentally determined so that the cooling surface 45 of the Peltier element 43 is warmed by the flow of the wind to prevent it from becoming higher than the dew point temperature at that time, and the cooling surface 45 is not frozen by overcooling. It is.

  Here, the Peltier drive circuit 47 is composed mainly of a general switch element such as a transistor that allows the power of the power supply circuit 21 to be turned on and off with respect to the Peltier element 43. By enabling so-called PWM control to change the interval of power application from 21, it is possible to change the heat drop generated in the Peltier element 43 by energization.

  A temperature / humidity sensor for measuring the temperature and humidity in the ambient air around the humidifying means 2 is provided in the control means 7, and the condensation at that time is detected by the microcomputer 18 from the temperature and humidity values measured by the temperature / humidity sensor. The operation of the Peltier drive circuit 47 is performed by the microcomputer 18 so as to calculate the corresponding dew point temperature necessary for the occurrence of the phenomenon and the temperature of the cooling surface 45 of the Peltier element 43 becomes the same corresponding to the calculated dew point temperature. By adjusting the voltage signal by software to vary and adjust the value of power application from the power supply circuit 21 to the Peltier element 43, it becomes possible to control the temperature of the Peltier element 43 more appropriately in accordance with the actual use environment conditions. Needless to say.

  Further, as shown in FIGS. 30 and 31, instead of vaporizing the humidified water accumulated in the humidifying tank 4 by the ultrasonic vibration element 5, a part of the impeller 48 is immersed in the humidified water and rotated to splash the humidified water 48. The impeller driving device 49 for rotating the impeller 48 is fixed to the inner wall of the humidifier outer shell 3 and the impeller 48 is rotated by the impeller driving device 49 so as to accumulate the humidified water in the humidifying tank 4. Of the Peltier element 43 by applying the subdivided humidified water to the heat generating surface 50 of the Peltier element 43 facing the blower air passage on the side of the blower opening 9 inside the humidifier shell 3. It is also possible to generate humidified air by evaporating with the heat of the heat generating surface 50. In FIG. 30, the thick arrow line indicates the flow of the wind due to the air flow, the dotted arrow line indicates the rotation of the impeller 48, and a plurality of small circles indicate the humidified water that is refined by splashing the impeller 48. Indicates the state.

  Here, the impeller driving device 49 uses a general electric motor that generates rotational power when a DC or AC voltage is applied, and a power supply circuit is a microcomputer 18 that forms the main body of the control means 7 when humidification is necessary. 21 starts energization of the Peltier element 43 via the Peltier drive circuit 47 and simultaneously drives the impeller via the impeller drive drive circuit 51 that turns on and off the power of the power supply circuit 21 to the impeller drive device 49.
