  The present invention solves such a conventional problem, and is effective by concentrating the range of the eyes of the image monitor user in a short time and performing more energy-saving humidification with less humidified water. An object of the present invention is to provide a humidifier for an image monitor that can prevent dryness and alleviate dry eye symptoms.

In order to achieve the above object, a humidifier for an image monitor of the present invention has an air intake opening for introducing air into one end of a hollow outer shell and air that has been humidified at the other end of the outer shell facing the air supply opening. A humidifying means provided with a blower opening for discharging air, wherein the humidifying means comprises a humidifying tank for storing humidified water inside the outer shell, an ultrasonic vibration element for vaporizing the humidified water stored in the humidifying tank, and a vaporizing means. The outer shell is fixed with a fixed convex portion at a position in contact with the upper portion of the outer periphery of the image monitor apparatus main body, and the humidifying means is removably hooked at the center of the upper upper portion of the image monitor apparatus main body. The air blowing opening is disposed so as to blow out air in a direction perpendicular to the image display surface of the image monitor .

  By this means, air that has been humidified with a range narrowed to the eyes of the image monitor user is blown.

  Further, the humidifying means is detachable from the image monitor apparatus main body.

  With this configuration, the humidifying means can be attached to and detached from the image monitor apparatus main body.

  Further, the humidified air blown by the humidifying means is generated using heat generated by the image monitor apparatus main body.

  With this configuration, the humidifying means vaporizes the humidified water by the heat generated by the image monitor apparatus main body.

  Further, the humidifying means is provided with a solar cell, and humidified air is sent using the electric power generated by the solar cell.

  With this configuration, the humidifying means performs humidifying air blowing using electric power generated by the solar cell.

  Further, the humidifying means is provided with a wind direction control means for restricting the direction of the humidified air blowing to the eyes around the image monitor user so that the air is blown to the peripheral area of the eyes.

(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 is provided for discharging the generated air to the outside of the humidifier shell 3. 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. Is output to the control device 7 to transmit the presence or absence of humidified water to the control device 7. A fixed convex portion 16 for fixing the humidifier shell 3 to the image monitor device main body 1 so as to be freely detachable is fixed to a position of the humidifier shell 3 in contact with the upper portion of the outer shell of the image monitor device main body 1.

  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 to blow out, and air is blown in the range of the size of the face about the position of 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. It is set so that it can be performed.

  Here, the water supply tank 10 is configured to be inserted and arranged so that an opening provided at one end is immersed in the surface of the humidified water in the humidifying tank 4, and the surface of the humidified water is accompanied by the progress of the humidifying operation. When the gap between the opening and the water surface is reduced, air enters the inside of the water tank, and humidification from the water tank until the gap between the opening and the water surface is eliminated by this entry. This is configured by a general automatic water supply method in which humidified water is supplied to the 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 is driven by a general electric motor that generates rotational power when a DC or AC voltage is applied.

  The control means 7 includes a microcomputer 17 that controls the operation of the entire humidifier, a high-frequency voltage generation circuit 18 that is controlled by the microcomputer 17 and drives the ultrasonic vibration element 5, and a blower drive circuit that also drives the blower 6. 19 and a microcomputer 17, a high-frequency voltage generation circuit 18, and a power supply circuit 20 that supplies power to the blower drive circuit 19.

  Here, the microcomputer 17 is a so-called one 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). A microcomputer is used, and when the electric signal of the contact point of the reed switch 15 output from the humidifying water detecting means 11 is received as an input, the presence of the humidifying water in the humidifying tank 4 is determined. In a state in which the presence of humidified water is determined, an operating voltage signal is output to the high-frequency voltage generation circuit 18 and the blower drive circuit 19 to drive the ultrasonic vibration element 5 and the blower 6 so as to perform humidification blow. It is a program.

  Here, the high-frequency voltage generation circuit 18 is configured by a general self-excited oscillation circuit that converts the power of the power supply circuit 20 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 19 is configured by a general switch element such as a relay that allows the power of the power supply circuit 20 to be turned on and off with respect to the blower 6.

  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 part of the outer shell of the image monitor device 1 by the fixed convex portion 16 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 electric signal from the humidifying water detecting means 11 to the computer 17, and the microcomputer 17 receives this output and the presence state of the humidified water in the humidifying tank 4. Judging.

  When the microcomputer 17 determines the presence of the humidified water in the humidifying tank 4, it supplies power from the power supply circuit 20 to the ultrasonic vibration element 5 and the blower 6 via the high-frequency voltage generation circuit 18 and the blower drive circuit 19. 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 compressed air is pushed out in the direction of the blower opening 9 provided at one end of the humidifier outer shell 3 facing the intake opening 8, so that the humidified air from the blower opening 9 is blown out.

  Here, since the air blowing opening 9 is opened toward the eyes of the image monitor user who uses the image monitor apparatus main body 1 with the humidifying means 2 attached to the image monitor apparatus main body 1, The humidified air blown out from the opening 9 is blown toward the eyes of 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 apparatus 1 by a fixed convex portion 16 fixed to the outer shell 3 of the humidifier. Needless to say, even if the humidifying means 2 is built in, there is no difference in its function and effect.

  Here, the fixed convex portion 16 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. However, the fixed convex portion 16 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.

  An electric louver capable of changing the blowing direction of the blowing opening 9 provided at one end of the humidifier outer shell 3 and an image input device for photographing an image monitor user positioned in the image display direction of the image monitoring device 1 in the humidifying means 2. The position of the eyes is determined and recognized by shape recognition from the image of the image monitor user captured by the image input device in the previous period, and the wind blown from the air blowing opening 9 toward the recognized image monitor user's eyes It goes without saying that the humidified air can be more accurately performed by correcting and finely adjusting the direction by operating the electric louver.

  Further, as shown in FIGS. 6 and 7, a heat sink 21 having a plurality of vertical fins is fixed to the side of the humidifying tank 4 facing the image monitor apparatus main body 1, and the inside of the humidifying tank 4 is further fixed. Of the image monitor apparatus body 1 in which the hygroscopic filter 22 is attached to the inner wall surface facing the fixed surface of the heat sink 21 in a state of being soaked in the humidified water, and the humidified water absorbed by the hygroscopic filter 22 is taken away by the heat sink 21. It is possible to humidify the air in the internal space of the humidifier shell 3 by evaporating with the generated heat.

  Here, the humidification tank 4 and the heat sink 21 are made of a material having high thermal conductivity, and are made using aluminum or a copper alloy as a base material.

  Here, the hygroscopic filter 22 is formed by forming a fine fiber into a sheet shape and is made of a material having high water absorption by capillary action and high corrosion resistance. For example, the hygroscopic filter 22 is formed by cutting a polyester fiber sheet. The resulting material is sandwiched between the reticulated plate materials so as to be in close contact with the attachment surface of the humidifying tank 4, and is arranged by pressure bonding.

  Further, as shown in FIGS. 8 and 9, a solar cell 23 is mounted on the top surface of the humidifier shell 3 of the humidifying means 2, and the electric power generated by the solar cell 23 is input to the power supply circuit 20 of the control means 7. By supplying it as electric power, humidified air can be blown by the electric power generated by the solar cell 23.

  Here, the solar cell 23 is configured by using an amorphous silicon-based material having high power generation capability in light emitted from a fluorescent lamp in consideration of use in a room of a general household or a business office. .

  When the power generated by the solar cell 23 is less than the amount of power required for the entire humidified air blow, the power supplied from the solar cell 23 is used only for either the ultrasonic vibration element 5 or the blower 6 and the others are commercial. Needless to say, the power supply circuit 20 is configured to be supplied from the power supply, so that the energy-saving humid air blow can be performed more than the consumption of the commercial power supply is reduced.

  Further, since the evaporation of moisture on the surface of the eyeball is easily promoted when the blown air directly hits the eyes, the humidified air blown from the blower opening 9 to the blower opening 9 of the humidifier shell 3 as shown in FIG. 10 and FIG. By arranging the wind direction control means 24 that restricts the air to be blown to the peripheral area of the eye without blowing directly to the user's eyes, drying of the image monitor user's eyes can be further alleviated.

  Here, the wind direction control means 24 has a central air passage restraint plate 25 arranged so as to block the central portion of the air blowing opening 9 of the humidifier shell 3 and a wind passage with a gap around the central air passage restraint plate 25. The air flow direction of the humidifier is controlled through the air passage of the air opening 9 that is vertically divided between the central air passage restraint plate 25 and the outer air passage restraint plate 26. The direction of the humidified air blown into two branches is set so as to blow against the peripheral area of the image monitor user's eyes.

  It should be noted that the central air passage restraint plate 25 is not fixed in the air blowing opening 9 and is movably fixed so that the blowing direction of the humidified air can be adjusted up and down so that the image monitor user can finely adjust the air blowing direction in actual use. Needless to say, it is possible to set a more optimal use environment by enabling the above.

  Further, as shown in FIGS. 12 to 14, a human body detecting means 27 for detecting the presence of an image monitor user in the air blowing direction is provided on the opening surface of the air blowing opening 9 of the humidifier shell 3. When the presence is detected, the humidifying unit 2 is configured to perform humidification blowing, so that the humidification unit 2 performs humidification blowing only when the image monitor user is actually using the image monitor. it can.

  Here, the human body sensing means 27 is constituted by a light reflection / reception type human body sensing system in which an infrared light emitting diode element 28 and an infrared light receiving phototransistor 29 are combined, and the infrared light emitted from the infrared light emitting diode element 28 is detected. The reflected infrared light is reflected by the target image monitor user, and is received by the infrared light receiving phototransistor 29. Upon receipt of the infrared light, the infrared light receiving phototransistor 29 is sent to the microcomputer 17 constituting the control means 7. By outputting the voltage signal, the microcomputer 17 is programmed to receive the voltage signal from the infrared light receiving phototransistor 29 to determine the presence determination of the human body and perform the humidified air blowing.

  The light emission intensity of the infrared light emitting diode element 28 and the arrangement interval and angle between the infrared light receiving phototransistor 29 are determined experimentally based on the distance between the image monitor user who uses the actual image monitor and the image monitor. However, the automatic operation of the humidifying air blow based on the detection of the image monitor user who prevents the false detection operation by setting so as to detect the human body existing at an interval of about 60 cm or less with respect to the image surface of the image monitor. be able to.

  Further, as shown in FIGS. 15 and 16, the driving power source of the blower 6 is a DC motor 30, and the blower drive circuit 19 constituting the control means 7 can be changed in output voltage by the control of the microcomputer 17. By using the variable DC power supply 31, the image monitor user can change the output voltage of the variable DC power supply 31 by the microcomputer 17 during humidification and change the rotational speed of the DC motor 30 to fluctuate the wind speed of the humidification blow. It is possible to alleviate the uncomfortable feeling that is always felt by receiving a constant air flow.

  Here, the variable DC power supply 31 is constituted by a general voltage control type switching power supply, and the control output of the variable DC power supply 31 of the microcomputer 17 is set to a D / A conversion power output type setting. It is configured so that the output voltage of the variable DC power supply 31 can be directly changed by software incorporated in the computer 17.

  Here, the blower air speed of the blower 6 controlled and shaken by the microcomputer 17 is as shown in FIG. 16, and the blown air duration is inversely proportional to the wind speed strength, and the air blow based on the generally called 1 / f fluctuation theory is used. It is programmed so as to be performed, and is set so that the humidified air blows in the range of 0 m to 1 m / second at which humans feel comfortable.

  Further, as shown in FIG. 17 and FIG. 18, humidified air is generated by disposing a moisture density increasing means 32 for increasing the humidity of the air by increasing the density of moisture in the air inside the humidifier shell 3. Therefore, it is possible to eliminate the need for supplying humidified water.

  Here, the moisture density increasing means 32 utilizes a so-called Peltier element 33 that generates heat drop between two opposing surfaces due to the thermoelectric effect by applying a direct current, and absorbs and exhausts heat. Cooling fins 34 for exchanging heat are affixed to the heat absorption surface side and arranged toward the inside of the humidifier shell 3, and heat exhaust fins 35 for heat dissipation are provided on the heat exhaust surface side of the Peltier element 33. And is exposed to the outside of the humidifier shell 3, and when the microcomputer 17 constituting the control means 7 determines that the humidification blow is to be carried out, the power circuit is connected via the moisture density increasing means drive circuit 36. The electric power from 20 is supplied to the Peltier element 33 to activate the heat absorption / exhaust effect of the Peltier element 33 to lower the temperature of the cooling fin 34, that is, the air around the cooling fin 34, that is, humidification To aggregate moisture contained in the air by cooling the air inside the outer shell 3 is intended to generate humidified air.

  Here, the cooling fins 34 and the exhaust heat fins 35 are made of a material having high thermal conductivity, and a plurality of fins are processed so that efficient heat exchange is possible using aluminum or a copper alloy as a base material. It was created.

  When the microcomputer 17 determines that the humidification blow is performed, the air around the cooling fin 34 is supplied from the intake opening 8 provided at one end of the humidifier shell 3 by the blower 6. Since the air is always replaced with the surrounding air, the moisture contained in the air around the humidifier shell 3 is always the source of the humidified water for generating the humidified air during the humidification blow. Further, the inside of the humidifier shell 3 is introduced in a state where the air around the humidifier shell 3 is pressurized by the blowing action of the blower 6, and the density becomes higher than the air around the humidifier shell 3. In addition, the moisture contained in the increased air density difference is used as a humidity increase of the humidified air generated inside the humidifier shell 3.

  Further, as shown in FIG. 19 and FIG. 20, an image using the image monitor is provided by providing blink timing instruction means 37 that conveys the blink timing to the image monitor user on the opening surface of the blower opening 9 of the humidifier shell 3. It is also possible to prompt the monitor user to perform blinking.

  Here, the blink timing instructing means 37 projects the light of the visible light emitting diode 38 that emits light by energizing the current to the image monitor user and stimulates it to blink the image monitor user. When the visible light emitting diode 38 is energized and controlled by the microcomputer 17 constituting the control means 7 and the microcomputer 17 determines that the humidification blow is performed, the visible light emitting diode is used. 38 is configured to blink.

  The period in which the visible light emitting diode 38 is blinked by the microcomputer 17 is set based on a value according to a general human blink interval, and is approximately 1 second at intervals of 5 to 20 seconds. The lighting cycle is programmed to be repeatedly executed, and the lighting cycle is changed randomly between 5 seconds and 20 seconds to prevent the image monitor user from becoming accustomed to repeated monotonous light projection. Thus, setting is made so that the blink timing can be transmitted more effectively.

  In addition, as shown in FIG. 21, the arrangement positions of the water supply tank 10 and the humidification tank 4 constituting the humidified water holding portion inside the humidifier shell 3 are arranged close to the installation surface of the image monitor device 1. Even when a problem occurs in which humidified water leaks from the water supply tank 10 or the humidifying tank 4, it is possible to prevent the humidified water from entering the image monitor device 1, so that humidified air can be blown more safely. At this time, the arrangement position of the control means 7 is also arranged above the water supply tank 10 and the humidification tank 4, so that the influence of the leakage of the humidification water on the control means 7 can be prevented, so that the humidification blow can be performed more safely.

  By sending humid air in the direction of the user's eyes, the symptoms of dry eye can be easily alleviated and improved, and it can also be applied to applications and fields such as monitoring or operation of devices that are likely to complain of dry eye symptoms.
