Description

  The present invention relates to a display device that informs a user of various information such as the operation status of the device, and in particular, a display device that enables the user to easily recognize the operation status, and the air in an air conditioner using the display device. It is related with the air conditioner which enabled the user to visually recognize the condition which harmonizes.

  Indoor air contains various substances that are uncomfortable or harmful to humans, such as dust, pollen, cigarette smoke, and exhaled air. In recent years, since houses are airtight, such harmful substances are likely to stay in the room. Therefore, natural ventilation is performed by opening indoor windows as appropriate. However, it is a fact that natural ventilation cannot be performed as expected in the recent severely polluted areas and homes and workplaces where people suffer from hay fever. Under such circumstances, an air purifier that is also an air conditioner having an air purifying function for purifying air has been attracting attention and has been widely spread.

  In addition, if the overall comfort of the indoor environment is considered, in addition to dealing with dust, house dust, germs, pollen, etc. floating in the room, multifaceted measures such as recovery from stress and fatigue are required. ing. In order to satisfy these requirements, air purifiers that remove dust, house dust, germs, pollen, and the like floating in the air have also had an ion generation function for relaxing people and generating ions. It has become possible to sterilize and sterilize bacteria and the like using this ion.

  In the above air cleaner, in order to spend more refreshingly indoors, it is also necessary to prepare the indoor environment. As one of the factors, humidity greatly affects. The humidity is generally said to be 40 to 60%. When the humidity is low, activities such as viruses become active and cause colds. Further, if the humidity is too high, it causes discomfort and generation of mold due to moisture. In order to eliminate these problems, the humidifier becomes very effective. For this reason, a device for adding a humidifying function to the air cleaner or the like to further improve the comfort has been proposed and is widely spread.

  In the air cleaner as described above, there has been proposed an apparatus that displays a state of purifying air using a display device. For example, a photoelectric dust detector for detecting dirt in the air is provided, and a display device that displays the degree of dirt in the air according to the detection status of the detector is provided. By operating this air cleaner, the display form will be changed in response to changes in the detection status by cleaning the air against the initial dirt display corresponding to the degree of dirt detected at the start of operation. I have to. This can display not only the degree of air pollution due to dust and the like, but also the situation in which the air pollution due to cigarettes and other odors is cleaned. For example, air cleaners described in Patent Documents 1 and 2 have been proposed as including such a display device.

  According to the air cleaner described in Patent Document 1, a number of two-color LEDs that are arranged in a strip shape are provided as a display device, and the degree of air contamination is displayed by changing the lighting color and number of lighting of these LEDs. Yes.

Patent Document 2 discloses an improvement of Patent Document 1, that is, an air cleaner in which the number of LEDs is reduced and the degree of contamination is displayed. Specifically, for example, red and blue LEDs are arranged at both ends of an elongated (rod-like) light-transmitting body, and one of the LEDs emits light from both ends, thereby causing the light-transmitting body to develop color and stain. The degree is displayed.
Japanese Patent No. 3666939 JP-A-2005-3334

  As mentioned above, in the thing of patent documents 1 and 2, when the air cleaner operates, the cleaning state of indoor air is displayed according to the detection state of the dust detector.

For example, according to the air cleaner described in Patent Document 1, the light emission colors of a plurality of LEDs are changed from one end according to the detection result of dust. Therefore, it is possible to easily recognize the display state when there is no air contamination and when the contamination is maximum. However, if the dirt state is in the middle, the number of LEDs that emit light simply changes in a strip shape, and even if the display state is visually recognized, the human air can fully recognize the actual air dirt situation. Can not. For example, it may not be said that the display is well matched between the human sense and the display state regarding how dirty the entire room is, and the user may feel uncomfortable.
In other words, even if the color changed sequentially from one end to a strip, it was impossible to sensuously grasp how much the display was in the entire room.

  Moreover, according to the display apparatus of the air cleaner of patent document 2, it is what displays a stain | pollution | contamination condition by the change of the ratio of the luminescent color in a rod-shaped light-transmitting body, and also how much is the dirt | cleaning condition of an intermediate state It is difficult to grasp whether it is dirty. In other words, even if it is possible to grasp the maximum dirt and the state without dirt, it is not possible to grasp the intermediate situation without a sense of incongruity.

  As described above, according to the display device of the conventional air purifier, even if the display is visually observed, the process of purifying the air cannot be sufficiently visually recognized, and it is simply displayed that it becomes beautiful. Therefore, it seems that there is a discrepancy between the actual recognition and the actual content of the display, and the sense of recognition that the user recognizes. For this reason, even if a display device is provided, the role of appealing to the user has not been fully demonstrated. Therefore, the current display device cannot fully express to the user that the degree of dirt on the entire room is reduced by the air cleaner, and can realize the degree of air purification without a sense of incongruity. There wasn't.

  Moreover, even if the air pollution such as dust or smell is displayed, it is difficult for the user to grasp the situation of the surrounding air. Because the odor in the air, which is likely to be linked to human sensuality, has a relatively small individual difference in the way it feels, and the display of detection results of human sensuality and odor is almost consistent, so there is little discomfort However, there is a large individual difference in how the dust in the air, which is difficult to be associated with human sensuality, and the display of the human sensuality and the dust detection results will vary, so the user feels uncomfortable with the display and cleans the air. I was wondering if the function worked properly.

In view of the above-described problems, the present invention is to provide a display device that further improves the visibility for the user and does not make the user feel uncomfortable.
The present invention allows the user to fully understand the situation that changes when the device operates by visually checking the display state, and can play a role as a display device. It is to provide a display device.

  In addition, the present invention makes it possible for the user to visually recognize the situation in which the air is conditioned by operating the air conditioner by applying the above-described display device to the air conditioner. With the goal.

In order to achieve the above object, a display device according to the present invention includes a plurality of light emitting elements, a transmissive member provided in front of the light emitting elements, and reflects the light from the light emitting elements to guide the light to the transmissive member. A light guide, and a space for diffusing light from the light emitting element is provided between the light guide and the transmissive member, and the light guide is formed to expand toward the transmissive member, When light from a plurality of light emitting elements is transmitted through a transmissive member, the light emitting elements are irradiated with light from each other light emitting element so that the boundary portion of the light is blurred.
Moreover, the air conditioner concerning this invention is provided with the detection sensor which detects the said display apparatus and the condition of air, and drives and controls a light emitting element according to the detection condition by this detection sensor.

According to the display device of the present invention, it is possible to easily recognize the changing display form by displaying the boundary portion of the light between the light emitting elements so as to be blurred, further improving the visibility for the user, and discomfort to the user. It is possible to display the user so that the user can easily understand the display contents.
According to the air conditioner equipped with the display device of the present invention, it becomes possible to express changes in the indoor air dirt status and the like, and display that is well matched between the user's sense and the display state It is possible to inform the user of the operating condition of the air conditioner, the air condition, etc. in an easy-to-understand manner.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Here, a display device provided in an air purifier will be described as an example, but the present invention is not limited to an air purifier, and a dehumidifier, a humidifier, a cooler, a heater that takes in air and adjusts the state of the air is described. The present invention can be applied to general air conditioners such as a machine or a device having a plurality of these functions. In addition, it goes without saying that the present invention can be applied to all devices including a display device. For example, it is needless to say that the present invention can be applied to a display device for grasping the operation status of the apparatus main body.

  FIG. 1 is a front perspective view showing an external appearance of an air cleaner body having a humidifying function according to the present invention. 2 is a side cross-sectional view taken from the center of the air cleaner shown in FIG. 1, and FIG. 3 is a cross-sectional view schematically illustrating the air flow of the air cleaner.

  First, the outline of the air cleaner will be described with reference to FIG. The air purifier 1 is disposed and operated at a proper place in the room. As a suitable place, it can be hung on the floor of a room or on a wall. In the air cleaner 1, a housing 10 is erected by the support of the base 11. The front surface of the housing 10 is covered with a front panel 12. As shown in FIG. 2, an intake port 10 a that takes in external air is formed on the rear surface of the housing 10. A blower outlet 10 d is formed in the upper rear portion of the housing 10. An operation panel 13 for a user (user) to perform an operation is provided on the front upper portion of the housing 10. Further, a detachable water supply tank 15 is mounted on the side surface of the housing 10. The front panel 12 is provided with an air monitor display panel (display device) 14 in the present invention for displaying the state of room air. The air monitor display panel 14 will be described in detail later.

The operation panel 13 includes a power button for turning on / off the power, an air purification setting button for setting the operation of the air purification function, a humidification setting button for setting the operation of the humidification function, Operation buttons such as an ion release button for turning on / off the emission, an ion switching button for switching the type of ions to be generated, a display switching button for switching display / non-display of the air monitor display panel 14, and the like according to the operated button In order to display the operating state of the air cleaner, a display unit is provided. This display unit is provided with a power supply display corresponding to the ON / OFF operation of the power button, which is indicated by lighting / extinguishing, a display unit indicating the operation status such as an air purification operation mode according to the operation of the air purification setting button, and the like. Yes.
For example, each time the air purification setting button is pressed, the air purification operation mode is switched such as automatic air volume, low air volume, and high air volume. Further, every time the humidification setting button is pressed, the humidification operation mode is switched such as humidification automatic, humidification weak, humidification strong, or humidification cut off. A display unit or the like for displaying the operation mode switched in this way is provided.

  Next, the internal structure of the housing 10 will be described. Inside the housing 10 is formed a ventilation path that communicates the inlet 10a and the outlet 10d, and a part of the blower 3 is provided in the ventilation path. The ventilation passage is configured with a part of the blower 3 as a boundary, an intake air passage 10b between the intake port 10a and a part of the blower, and an exhaust air passage 10c between a part of the blower and the outlet 10d. Has been.

The intake air passage 10b is provided with an air purification filter 2 for purifying the intake air. That is, the air purifying filter 2 is disposed at a position corresponding to the air inlet 10 a provided corresponding to the back surface of the housing 10. Therefore, when the blower 3 is driven, air is sucked from the intake port 10 a and passes through the air purification filter 2. This air passes through the intake air passage 10b and is blown out from the outlet 10d via the exhaust air passage 10c. As shown in FIG. 2, an ion generator 16 is provided in the exhaust air passage 10c. Therefore, when the ion generator 16 operates, the ions generated by the ion generator 16 are released together with the air blown out from the air outlet 10d.
The blower 3 includes a motor 3a and a fan 3b. The fan 3b which comprises the air blower 3 is arrange | positioned in the said ventilation path, takes in air through the said inlet 10a by rotating this fan 3b, and blows off air from the blower outlet 10d.

  Sensors such as a temperature sensor 41, a humidity sensor 42, a dust sensor 43, and an odor sensor 44 that are not individually shown in FIG. 2 between the air inlet 10 a and the air purification filter 2, that is, upstream of the air purification filter 2. 17 is installed at an appropriate place to detect the indoor air condition. The temperature sensor 41 detects the temperature of room air, and the humidity sensor 42 detects the humidity of room air. The dust sensor 43 includes a light emitting element and a light receiving element, and detects particles such as dust floating in the indoor air. The odor sensor 44 is a semiconductor gas sensor that utilizes a change in resistance when gas is adsorbed on the surface of a sensor made of a metal oxide, and detects an odor component in room air. The detection results of the sensors 17 are displayed on the air monitor display panel 14 described in detail later. The dust sensor 43, the odor sensor 44, and the like are conventionally known and do not have a special configuration in the present invention.

  As shown in FIG. 5, the air monitor display panel 14 includes a humidity monitor 51 that displays the current humidity level, an odor monitor 52 that displays the level of odor, and a house dust monitor that displays the level of dust / house dust. 53 and an ion monitor 54 for displaying the operation status of an ion generator to be described later. Since the air monitor display panel 14 is provided on the front panel 2 of the main body of the air purifier 1, the display may be an obstacle when it is desired to make the room dark, such as at bedtime. In this case, by operating a display switching button provided on the operation panel 13, the display element of the air monitor display panel 14 can be turned off and not displayed.

  In this manner, the operation panel 13 that displays the operation buttons and the driving situation and the air monitor display panel 14 that displays the current air condition based on the detection values of the sensors 17 are divided and displayed separately. The user (user) can easily visually recognize the item he / she wants to know and can quickly obtain necessary information. In addition, since the display is divided as described above, the space required for each display is reduced, so that the degree of freedom in arranging the operation panel 13 and the air monitor display panel 14 is improved, and the design is improved.

  The air purification filter 2 for purifying the intake air is detachably attached to the housing 10. For example, the back surface part which comprises the inlet port 10a can be attached or detached with respect to the housing | casing 10, and the air purifying filter 2 can be attached or detached by removing this back surface part. The air purifying filter 2 for purifying (cleaning) air is, for example, a pre-filter that collects large dust in the air in order from the air suction side, activated carbon, or the like in a predetermined frame. It has a three-layer structure that incorporates a deodorizing filter that deodorizes the inside and a dust collecting filter that collects dust in the air, and removes dust and odorous components contained in the air taken in from the air inlet 10a. Is done.

  The air that has passed through the air cleaning filter 2 flows into the humidification unit 18 provided at the lower part of the housing 10. The humidification unit 18 is provided in the intake air passage 10b between the air purification filter 2 and the fan 3b of the blower 3. The humidification unit 18 includes a water supply tank 15 that is detachably mounted, a water storage container 5, a water absorption filter 7, a rotary drum 4 that holds the water absorption filter 7 therein, and a drive mechanism 9 that rotationally drives the rotary drum 4. It is configured.

  A tank mounting portion for mounting a water supply tank 15 is provided at one end of the water storage container 5. The water supply tank 15 is a box-type container that can store water therein, and is mounted on the tank mounting portion to supply water to the water storage container 5, and a substantially constant amount of water is stored in the water storage container 5. It has become so.

A pair of arms 6 are provided on the side wall of the water storage container 5 so as to face each other, and the rotating shaft of the rotating drum 4 is supported by the arms 6.
The water absorption filter 7 is formed of a material having water absorption, for example, a polystyrene foam, is held in the rotating drum 4, and is rotated by the rotation of the rotating drum 4. The lowermost part of the rotating drum 4 supported by the arm 6 is disposed so as to be slightly away from the bottom surface of the water storage container 5, and the rotation is not hindered.

  The drive mechanism 9 has a drive gear 104 and a roller 105. The lower part of the roller 105 is in contact with the rotary drum 4, and the motor shaft of the drive motor of the drive mechanism 9 is connected to the drive gear. Therefore, when the drive shaft rotates, the drive gear 104 rotates and the roller 105 rotates. Then, the rotating drum 4 in contact with the roller 105 is rotated.

  When the drive mechanism 9 rotates the rotary drum 4, the water absorption filter 7 held by the rotary drum 4 also rotates, and accordingly, the lower part of the water absorption filter 7 is sequentially immersed in the water in the water storage container 5. The whole 7 gets wet. Then, the air is humidified by the intake air passing through the water absorption filter 7 that has absorbed water. Thereby, air can be humidified to the set humidity state.

The water absorption filter 7 is formed in a substantially cylindrical shape corresponding to the hollow cylindrical portion of the rotary drum 4, but has a shape in which a part of the circumferential portion is cut away. That is, a non-immersed part having a partially shortened radial length is formed. The size of the notched part, that is, the length from the rotation center of the rotating drum to the peripheral edge of the non-immersion part is set to be shorter than the distance from the rotation center of the rotating drum to the water surface of the water storage container. Yes. Therefore, in a state where the rotating drum 4 is rotated and the non-immersed part of the water absorption filter 7 faces downward, the water absorption filter 7 is not immersed in the water in the water storage container 5.
Therefore, when the humidification cut-off mode is set by the operation button of the operation panel 13 or when the humidification is not performed because the humidity is high, the rotary drum 4 is stopped at a position where the non-immersed portion of the water absorption filter 7 faces downward. . In this state, since the water absorption filter 7 is not immersed in the water in the water storage container 5 and does not absorb water, the air passing through the humidification unit 18 is not humidified. In this way, it is possible to switch whether or not humidification is performed by switching between rotation and stop of the rotating drum 4.

Further, the ion generator 16 provided in the exhaust air passage 10c of the air purifier 1 discharges ions to the exhaust air passage 10c by applying a high voltage between the discharge electrodes arranged opposite to each other to cause discharge. . The ion generator 16 can switch the type of ions to be generated, and can generate only positive ions, only negative ions, or positive and negative ions. The ion species to be generated can be freely set and selected by operating an ion switching button provided on the operation panel 13.
By releasing air containing positive ions and negative ions from the air outlet 10d, it is possible to remove indoor sterilization and odor, or release only negative ions to obtain a relaxation effect. In this manner, by disposing the ion generator 16 in the exhaust air passage 10c leading to the air outlet 10d, it is possible to prevent the disappearance of ions due to the collision with the blower 3. Only the electrode for generating ions may be disposed facing the exhaust air flow path 10c, and the ion generator 16 itself (power supply unit or the like) may be disposed at another position.

  The configuration of the air cleaner 1 has been described above. With respect to this air purifier 1, referring to FIG. 4, display of the display device according to the present invention for displaying the above-described air purification, discharge of air containing ions, and the operation status of the air purifier 1. A control circuit for controlling the state will be described. FIG. 4 is a block diagram showing the main configuration related to the operation of the air purifier 1. The overall operation of the air cleaner 1 is controlled by the control unit 40. The control unit 40 includes a drive mechanism control circuit 45 that operates a drive mechanism 9 for rotating the rotating drum 4 that is subjected to humidification, and a fan motor drive circuit 46 that controls the rotation operation of the motor 3a of the blower 3 that creates an air flow. , And an ion generator drive circuit 47 that drives and controls the ion generator 16 that emits necessary ions is connected. Sensors 17 such as a temperature sensor 41, a humidity sensor 42, a dust sensor 43, and an odor sensor 44 are connected to the control unit 40, and detection values from the sensors are sent to the control unit 40.

  The drive mechanism control circuit 45, fan motor drive circuit 46, and ion generator drive circuit 47 include input operations from various operation buttons on the operation panel 13, temperature sensor 41, humidity sensor 42, dust sensor 43, and odor sensor. A command is sent from the control unit 40 that controls based on the detected value from 44. Thereby, the drive mechanism 9, the blower 3, and the ion generator 16 are driven via the drive mechanism control circuit 45, the fan motor drive circuit 46, and the ion generator drive circuit 47.

  As described above, the dust sensor 43 includes the light receiving element and the light emitting element. The light receiving element receives light emitted from the light emitting element through the outside air. Further, the illuminance at the light receiving element at that time is detected. Since the illuminance detected by the light receiving element decreases as the dust increases, the amount of dust in the air can be indirectly detected.

  The odor sensor 44 is provided with a predetermined oxide semiconductor so as to come into contact with the outside air, and detects a change in electric resistance caused by adsorption and reaction of a gas having odor on the surface of the oxide semiconductor. As a result, it is possible to detect the concentration of a gas having an odor, and as a result, it is possible to function as an odor sensor that indirectly detects the intensity of the odor in the air.

  The control unit 40 also has various operation buttons 48 for selecting and operating various operation modes provided on the operation panel 13, and an operation display element 49 for displaying the operation state of the operation buttons, the operation mode, and the like. , And a monitor display element 50 for displaying the air purification status by the air monitor display panel 14. As described above, the operation button 48 of the operation panel 13 includes a power button for turning on / off the power, an air purification setting button for setting the operation of the air purification function, and an operation setting for the humidification function. A humidification setting button, an ion release button for turning on / off ion emission, an ion switching button for switching ion species to be generated, a display switching button for switching display / non-display of the air monitor display panel 14, and the like are included.

  The operation display element 49 provided on the operation panel 13 is a power display LED that indicates ON / OFF of the power source according to the operation of the power button by turning on / off, and an air purification operation mode according to the operation of the air purification setting button. LED for indicating the air purification operation mode indicating lighting, a humidifying operation mode indicating LED indicating lighting for the humidifying operation mode according to the operation of the humidification setting button, a display LED indicating the ion species to be generated, and the like. And the monitor display element 50 of the air monitor display panel 14 which is a display apparatus of this invention is comprised from LED which is a several light emitting element demonstrated in detail later for displaying the purification | cleaning condition of air.

  Here, each time an operation button 48 on the operation panel 13, for example, an air purification setting button for setting the operation of the air purification function, is pressed, an air purification operation mode such as automatic air volume, low air volume, high air volume, etc. Is switched, the LED indicating the mode is driven, and the operation mode is displayed. Each time the humidification setting button is pressed, the humidifying operation mode is switched, such as automatic humidification, weak humidification, strong humidification, or humidification off, and the display is performed. Therefore, an input from the operation button 48 according to the user's operation is sent to the control unit 40, and control according to the mode is executed, and at the same time, the operation mode is displayed by the operation display element 49.

  Then, the control unit 40 drives and controls a plurality of LEDs, which are monitor display elements 50 of the air monitor display panel 14 provided separately from the operation panel 13, according to the detection status of the various sensors 17. The monitor display element 50 displays a humidity display LED 31 that displays the current humidity level, which will be described in detail later with reference to FIGS. 5 and 6, an odor display LED 32 that displays the intensity of odor, and the level of dust and house dust. House dust display LEDs (33a to 33d) and ion generation display LEDs 34 that display ON / OFF of ion generation by lighting / extinguishing.

  The various LEDs of the operation display element 49 and the monitor display element 50 described above are turned on / off according to a command from the control unit 40. Among them, the humidity display LED 31 is based on the detection value from the humidity sensor 42, the odor display LED 32 is based on the detector of the odor sensor 44, and the house dust display LEDs (33 a to 33 d) are based on the detection value of the dust sensor 43, The ion display LED 34 is driven and controlled in accordance with the operation of the ion generator 16.

  Next, the configuration of the display device of the present invention which is the air monitor display panel 14 will be described in detail. Although the display device of the present invention has been briefly described above, the air monitoring result by the sensors 17 is displayed, and the display content is improved so that the visibility can be easily grasped by the display content.

The holding positions of the house dust display LEDs (33a to 33d) fixed by the four mounting portions (73a to 73d) are respectively located at the center of the triple circle which is a light transmitting portion formed on the transmission sheet 85. It corresponds.

In addition, each attachment portion (73a to 73d) is provided on a bottom portion that hangs down from the plane portion 93, and between the attachment portion (73a to 73d) and the plane portion 93, from the attachment portion (73a to 73d). Light guide portions (63a to 63d), which are light guide bodies configured by a drooping surface having a conical shape (a trumpet shape) gradually spreading toward the flat portion 93, are formed. The light from each LED is guided by the light guide parts (63 a to 63 d) and reaches the transmission sheet 85 through the space part 95.
Since each light guide part (63a-63d) is gradually spread toward the plane part 93, the hanging surface (light guide part) is inclined. The drooping surface in the vicinity of the flat portion 93 is further inclined, and is formed such that the degree of spread of the opening on the flat portion 93 side of the light guide portions (63a to 63d) is further increased. For example, the curved shape of the hanging surface or the inclination angle is further increased so that R (R) is formed in the vicinity of the plane portion 93.

  In addition, the ion monitor 54 of the air monitor display panel 14 is provided with an ion display LED 34 for displaying on / off of ion emission by the ion generator 16 at the center thereof. The flat portion 93 of the ion monitor 54 is provided with an attachment portion 74 for attaching the ion display LED 34 and a light guide portion 64 connected thereto. The attachment portion 74 and the light guide portion 64 have substantially the same structure as that described for the house dust monitor 53. The mounting position of the ion display LED mounting portion 74 on the ion monitor 54 corresponds to the center of the mark indicating ions on the transmission sheet 85.

  Further, the odor monitor 52 is provided with an odor display LED 32 for displaying the odor level. The support support 81 is provided with an attachment portion 72 for attaching the odor display LED 32 and a light guide portion 62 connected to the attachment portion 72. The light guide unit 62 extends to the immediate vicinity of the transmission sheet 85. Therefore, the light from the odor display LED 32 does not leak into the space 95 and diffuse. In addition, the light guide portion 62 has almost no inclination and is formed of a column-shaped hanging surface that rises substantially vertically. The attachment position of the odor display LED 32 by the attachment portion 72 in the odor monitor 52 is provided corresponding to the center of one concentric triple circle provided in the odor monitor 52 of the transmission sheet 85. The triple-circular translucent part of the monitor 52 is approximately the same size as the opening of the light guide part 62.

  The humidity monitor 51 is disposed so as to correspond to the lower support portion 92 of the support support 81. The humidity monitor 51 is provided with six humidity display LEDs 31 at positions corresponding to the numerical values indicating the humidity shown on the transmission sheet 85, and the support support 81 has six humidity display LEDs 31 for attaching each humidity display LED 31. Mounting portion 71 and a light guide portion 61 connected thereto are formed. The light guide part 61 is provided between the surface of the lower support part 92 in contact with the transmission sheet 85 from the attachment part 71, and is formed by a cylindrical bottom surface that rises substantially vertically. Since the light from the humidity display LED 31 guided by the light guide unit 61 reaches the transmission sheet 85 immediately after passing through the light guide unit 61, there is almost no diffusion of light in this portion.

  In addition, the mounting portions (71, 72, 73a to 73d, 74) and the light guide portions (61, 62, 63a to 63d, 64) constituting the display device of the present invention have at least a surface that does not transmit light. Is reflected (including irregular reflection). Therefore, a reflector can be formed on the surface of the mounting portion or the light guide portion, or it can be formed of a member that itself does not transmit light.

  The support support 81 comprising the display unit 80 includes upper and lower support portions 91 and 92, attachment portions (71, 72, 73a to 73d, 74), a light guide portion (61, 62, 63a to 63d, 64), and a light shielding plate. FIG. 7 shows a structure obtained by integrally molding 94, a support piece 96, and the like. However, the support portion, the attachment portion, the light guide portion, and the like may be configured as separate members and assembled as a whole as shown in FIG.

Next, display control of the air monitor result in each display monitor will be described including the block diagram of FIG.
The humidity monitor 51 displays the current humidity in the room (around the air purifier) via the control unit 40 based on the humidity detection result by the humidity sensor 42 of the air taken in from the air inlet 10a. For example, the humidity display LED 31 includes six LEDs that emit green light. Based on the detection result of the humidity sensor 42, the humidity display LED 31 arranged corresponding to the numerical value (30, 40, 50, 60, 70, 80, etc.) indicating the humidity on the transmission sheet 85 is controlled to be lit. The Humidity is displayed by the light from the lit LED illuminating the translucent portion showing the corresponding numerical value from below the transmissive sheet 85.

The odor monitor 52 displays the level of odor intensity based on the detection result of the odor sensor 44. The odor display LED 32 is a multi-color LED, and emits light in green, red, or an orange that is a mixed color thereof according to the output voltage state based on the detection value of the odor sensor 44.
Information on the detection result by the odor sensor 44 is transmitted to the control unit 40. The control unit 40 compares the detection result (the resistance value of the oxide semiconductor) by the odor sensor 44 with two predetermined threshold values. As a result, the odor intensity (odor gas concentration) in the current outside air (air) is evaluated in three stages.

  As a result of this comparison, if the odor is evaluated to be the weakest, the odor display LED 32 emits green light. Similarly, if it is evaluated to be weak next, it emits orange light, and if it is evaluated that the most odor is strong, it emits red light to display the odor level. Thus, since the odor is weaker as the display state is closer to green and the odor is stronger as it is closer to red, the user (user) can intuitively understand the state of odor in the air. ing.

The house dust monitor 53 displays the level of house dust according to the output voltage state of the dust sensor 43. Corresponding to the four triple light transmitting portions formed on the transmission sheet 85, as shown in FIG. As the dust display LED, a first display LED 33a, a second display LED 33b, a third display LED 33c, and a fourth display LED 33d are arranged. In other words, the first to fourth display LEDs 33a to 33d are not arranged on the same straight line, but are arranged at positions having a deviation in two directions of the horizontal direction and the vertical direction. Therefore, it is not arranged along a straight line but is arranged at a two-dimensionally shifted position. Therefore, the display form is not a line display but a plane. For example, the entire house dust monitor (display area) can be regarded as a room in which the air purifier 1 is installed.
The first to fourth display LEDs (33a to 33d) are multi-color LEDs that emit green, red, or orange, which is a mixed color thereof. According to the multi-color LEDs, display with three kinds of emission colors. (Including four states where the LED does not emit light) can be realized.

  As described above, the light guide portions (63a to 63d) that guide light emitted from the first to fourth display LEDs (33a to 33d) that are house dust display LEDs extend to the vicinity of the transmission sheet 85. A space portion 95 is provided between the transmission sheet 85 and the light guide portions (63a to 63d). Further, the side walls of the light guides (63a to 63d) are directed from the LEDs (33a to 33d) toward the side closer to the transmission sheet 85 in order to reflect and diffuse the light emitted from the LEDs (33a to 33d). Thus, the cross-sectional opening is formed in a tapered shape.

  The inclination of the side wall of the light guide unit (63a to 63d) is formed so that the inclination of the side wall of the light guide unit arranged at the upper right is increased, and the size of the opening on the side closer to the transmission sheet 85 is set. In comparison, the opening formed by the light guide portion 63a corresponding to the first display LED 33a arranged at the lower left is the smallest, and the opening of the light guide portion arranged at the upper right is larger, The opening formed by the light guide portion 63d corresponding to the fourth display LED 33d disposed on the upper right is formed to be the largest.

  The light emitted from the first to fourth display LEDs (33a to 33d) passes through the light guides (63a to 63d), so that the light irradiation range is expanded, and then the light guide (63a). ˜63d) and the space 95 formed between the transmissive sheet 85. Since there is no member for guiding light in a predetermined direction in the space portion 95, the light is further diffused radially from the end portions of the light guide portions (63a to 63d). Therefore, the irradiation range of the light from the adjacent display LEDs that have diffused through different paths overlaps, and the light emitted from the adjacent display LEDs reaches the transmission sheet 85 in a mixed state.

Since the light guide part corresponding to the display LED arranged on the upper right side has a larger opening on the side closer to the transmission sheet 85, light can be diffused over a wide range. Therefore, on the transmissive sheet 85, the overlapping range of the light between the adjacent display LEDs becomes larger toward the upper right part.
Since the light diffusion range increases toward the upper right of the house dust monitor 53, the light transmitting portion of the house dust monitor 53 is formed larger as it is disposed at the upper right. Depending on the light diffusion range, increase the number of light transmitting parts, increase the number of light transmitting parts without changing the size of the light transmitting parts, or change the shape of the light transmitting parts. May be.

  In addition, since the light transmission part is formed in the light transmission part 85 according to the irradiation range of the light spread by the light guide part (61, 62, 63a-63d, 64) and the space part 95 in the transmission sheet 85, humidity Unlike the light-transmitting portions of the monitor 51 and the odor monitor 52, the light-transmitting portions of the house dust monitor 53 are larger than the openings on the light-transmitting sheet 85 side of the corresponding light guide portions (63a to 63d). Is formed.

  The light from the first to fourth display LEDs (33a to 33d) is diffused by the light guide part (63a to 63d) and the space part 95. The light reaching the transmission sheet 85 is distributed so that the intensity of the light becomes stronger in the central part of the diffusion range where the distance from the light emitting part of each LED is short, that is, in the central part of each triple circle. As a result, when light reaches the transmissive sheet 85, the central portion of the transmissive sheet 85 is displayed darker. On the other hand, since the intensity of the light reaching the peripheral part of the triple circle is weak, even if the adjacent LEDs emit light in the same color, the boundary part between the LEDs becomes blurred. , The intensity is displayed as continuously changing. Each circle for connecting the boundary portions further emphasizes the connected state and promotes the display effect.

When the adjacent display LEDs are lit in different colors, as an example, the uppermost fourth display LED 33d is displayed in “orange”, and the third display LED 33c arranged thereunder is displayed in “red”. , The border is not clear, and “red” and “orange” change colors faintly and are displayed in a blurred state. For this reason, the color change at the boundary portion is blurred and displayed in the form of a gradation in which the color changes continuously and naturally.
Therefore, as a result, the house dust monitor 53 of the air monitor display panel 14 displays the light emission color and the light emission intensity as changing continuously, and the user (user) continuously shows the house dust contamination level. It can be recognized as changing.

  In addition, the above-described display state further increases the effect of promoting the spread of light by forming the vicinity of the flat surface portion 93 in the light guide portion to have a larger inclination, curvature, or R shape. As a result, as described above, the boundary and boundary of the color change portion are blurred and are recognized in a state of being loosely connected. In addition, since the overlapping range of light emitted from adjacent LEDs becomes wider as going to the right side, the boundary of the light is more vague and difficult to discriminate as the color change part is on the right side. Can also be recognized. In addition, the first to fourth display LEDs (33a to 33d) are not arranged on the same straight line but are arranged at positions shifted two-dimensionally, and therefore the first to fourth display LEDs (33a to 33d) of the first to fourth display LEDs (33a to 33d). By sequentially changing the emission color, it is possible to display the change in a two-dimensional plane direction, which helps to make the display feel spatially wide.

  The light emitted from the adjacent LEDs reaches the space portion 95 through the light guide portion 63 and is further diffused in the space portion 95, so that the irradiation ranges of the light from the adjacent LEDs on the transmission sheet 85 are mutually different. The distance between adjacent LEDs, the size of the light guide unit, the size of the space unit, the size of the light transmitting unit in the transmission sheet 85, and the like are appropriately determined so as to overlap.

The above will be described in more detail according to the process in which the air purifier 1 operates and the air is purified.
First, the power source of the air cleaner 1 is turned on, and the air cleaning operation is started. At this time, the indoor air is sucked from the air inlet 10 a on the back surface of the air cleaner 1, so that the degree of dirt in the indoor air is detected by the dust sensor 43. The detection result of the dust sensor 43 is transmitted to the control unit 40. The control unit 40 compares the detection result (the illuminance at the light receiving element) by the dust sensor 43 with eight predetermined threshold values. As a result, the amount of dust in the outside air (air) is evaluated in nine stages.

  For example, if the dirt is maximum (when the output of the dust sensor 43 is maximum due to dirt), all the display LEDs (33a to 33d) in the house dust monitor 53 are all lit red and pass through the transmission sheet 85. The entire light is displayed in “red” by the light to be displayed, and it is displayed that the air contamination is maximum. At this time, if the ion release button is set to ion release and the ion generator 16 is activated, the ion display LED 34 of the ion monitor 54 is driven to emit light in blue, for example.

  In the humidity monitor 51, the humidity display LED 31 at a position corresponding to the humidity detected by the humidity sensor 42 is selected, and in the odor monitor 52, the odor display LED 32 is determined according to the odor detected by the odor sensor 44. Lights on. For example, if the odor is strong, that is, if the odor level is high, the odor display LED 32 is displayed in “red”. When the odor is reduced, the display gradually changes to “orange” and “green”.

  Therefore, if attention is paid to the situation of the house dust, as described above, if the dirt state of air is detected at the maximum, all the house dust display LEDs (33a to 33d) are driven in “red”. . This display state is as described above, and the house dust monitor 53 is displayed in red as a whole. If the user (user) visually observes the display state, it can be visually recognized from the overall color state that the air in the entire indoor space is very dirty.

  And the air cleaner 1 continues operation | movement, and the inhaled air is purified by the air purifying filter 2 grade | etc.,. If the dust sensor 43 detects the situation where the air is being purified and it is determined that the dust level has decreased by one, for example, the emission color of the fourth display LED 33d is “orange”, and the other first to first The three display LEDs (33a to 33c) are lit red. At this time, the diffusion range of the light emitted from each LED overlaps at the boundary between the third display LED 33c and the fourth display LED 33d of the house dust monitor 53, and “red” and “orange” are mixed and continuously. It seems that the color changes naturally.

  Furthermore, as the air in the room is further purified, the “color” of the first to fourth display LEDs (33a to 33d) is gradually changed. For example, as the air is purified and cleaned, the light emitting element changes from “red” to “orange” to “green”. Further, the change first changes from the uppermost fourth display LED 33d and gradually changes to the lowermost first display LED 33a.

  FIG. 8 shows the display change state described above. As an example in the present invention, the house dust monitor 53 shows a state in which the emission color of the first to fourth display LEDs (33a to 33d) is changed according to the detection level of the dust sensor 43. That is, the display state is shown in nine stages from the maximum (8) level to the minimum (0) level. In this figure, at level 7, the boundary between the third display LED 33c and the fourth display LED 33d, at level 6, the boundary between the second display LED 33b and the third display LED 33c, and at level 5, the first display LED 33a and the second display LED 33b It is easy to recognize that the colors are mixed at the boundary, and the boundary is blurred and the color continuously changes. For example, it is possible to easily recognize a situation where the degree of air contamination in the entire room changes with a spatial variation compared to the case where the degree of air contamination is maximum. Therefore, the house dust situation in the entire room can be displayed in a state close to the actual feeling of the user (user), and the air situation can be recognized without a sense of incongruity.

  Further, as the air purification further proceeds, the level of the fourth display LED 33d changes to “green” at level 3, and the boundary portion of the light at the boundary with the third display LED 33c at that time is blurred, and the color is softly mixed And the color change at that time can be recognized. In addition, since the color change, that is, the state of changing from “orange” to “green” can be easily recognized, a display matching the air state in the entire room can be performed.

  Here, according to the display device of the present invention, in addition to the above-described display, the ratio of the translucent portion on the transmissive sheet 85 which is the display portion above the lower portion is further increased. The emission color is switched from the top. Therefore, when the color changes from the large translucent portion, in addition to the above-described action, the degree of attention is increased and the visibility is improved. In other words, the user (user) visually observes the situation in which the color has changed, and the effect of recognizing the situation in accordance with the display is promoted.

  Moreover, since the change changes from the upper part instead of the lower part, it becomes easier to grasp the situation of the change as a human sense. Therefore, the above-described effect is further promoted.

  Furthermore, in the display device of the present invention, when the first to fourth display LEDs (33a to 33d) are turned on, the connection state of the four triple circles of the house dust monitor 53 is displayed well. In addition, by providing a transmission portion that is not disposed at a position corresponding to the LED, for example, a circle that transmits light, at an appropriate position of the transmission sheet 85, the effect of further promoting the connection is increased. In addition, the effect can be further expected by gradually increasing the circle to a triple circle.

  As described above, in the display device of the present invention, when the operation status of the device, particularly in the air purifier, the air cleaning status is displayed, the display status and the air in the room are actually cleaned. This increases the effect that the user (user) can recognize the situation being performed in a state in which matching is obtained sensuously. In particular, the state of connection is good and the state of color change can be expressed accurately. Therefore, the state in which the actual air is being cleaned can be grasped by a display form of the entire room, for example, and the user (user) can perceive the clean state by a change in the display form. Therefore, the visibility of the display form can be improved.

In addition, as described above, the display of humidity, odor, etc., in which the detection results are not likely to be misaligned by human sensuality and sensors, etc., are displayed in order to allow the user (user) to accurately grasp the air condition. By guiding the light from the LEDs (31, 32) to the transmission sheet 85 via the light guide (61, 62), the detection result is displayed specifically and clearly without diffusing the light over a wide area. Yes.
However, dust and house dust, such as house dust, that has a large individual difference in the way it feels, is likely to cause a shift in the display of detection results by human sensuality and sensors, etc. The level is not displayed discretely and step by step, but is displayed so as to change continuously in order to display it in accordance with human sensation and to have a spatial extent. As a result, it is possible to inform the user (user) of the operation status of the air cleaner and the monitoring results of the air status without causing any contradiction with the individual senses, and the air cleaner is operated normally. You won't be wondering if you are.

  In the above description, the mode of displaying the operation status of the apparatus using a plurality of LEDs has been described. However, in the display device of the present invention, even if one light source is used, the situation can be displayed and recognized well.

For example, in the ion monitor 54, as shown in FIGS. 6 and 7, according to the configuration of the light emitting unit 80, if one ion display LED 34 emits light in “blue”, the generation state of ions can be displayed. .
By turning on an ion generation switch on the operation panel 13, the ion generator 16 is driven, and positive and negative ions are generated for sterilization, for example. The generated ions are discharged from the air outlet 10d together with the purified air through a filter or the like. In order to display the situation, the ion display LED 34 is turned on, and the transmission sheet 85 is irradiated to “blue” with visible light.

The light is reflected by the light guide unit 64, passes through the space unit 95, and irradiates (displays) the ion monitor 54 of the transmission sheet 85 over a wide range. The light is irradiated with light having a particularly deep color to the translucent part near the center of the ion mark of the ion monitor 54, and a display with a spread is performed so that the peripheral part gradually becomes light with the light at the center. For this reason, when ions are ejected from the outlet 10d, it is possible to display sensibly so as to be ejected with a spread around the periphery.
Here, if an ion sensor for detecting discharged ions is provided in the vicinity of the air outlet 10d and the amount of ions is detected, a plurality of color LEDs are used for the ion display LED 34 in accordance with the detection result. The colors may be displayed sequentially, or the lighting color may be changed depending on the type of ions generated.

  Therefore, the ion monitor 54 can display the display in accordance with the situation where the apparatus is actually operating, as in the present invention. Therefore, the user (user) recognizes the display form as if ions are actually generated by viewing the display. Therefore, the situation can be easily recognized without feeling the difference between the display where ions are generated and the actual situation.

  In the present embodiment, ions are released using the ion generator 16, but other substances having a bactericidal effect such as ozone and radicals may be released using an ozone generator or the like.

  In this embodiment, the house dust display and the ion monitor have been described. However, the present invention is not limited thereto, and may be applied to a humidity display and an odor display, and may be applied to, for example, an apparatus that displays the operation status of the apparatus main body. Needless to say.

  In the present embodiment, in order to diffuse the light emitted from the display element, the side wall of the light guide portion is inclined, the opening on the transmission sheet side is enlarged, and the space portion 95 is provided behind the transmission sheet 85. However, the present invention is not limited to this, and a member for diffusing light, for example, a diffusion sheet or a scattering plate, is disposed in a space formed between the light guide unit and the transmission sheet to diffuse the light. Adjacent light may be mixed. When a diffusion sheet, a scattering plate, or the like is used, the side wall of the light guide portion is not inclined and the opening portion need not be enlarged.

In this embodiment, a multi-color LED (two-color LED) is employed as a device that emits light in a plurality of colors (multi-color light-emitting device). A plurality of colors of light can be obtained, for example, by applying a coating material to the opening of the light and diffusing mixed colors.
Further, the number of LEDs is not limited to four, and any number of LEDs may be used. In addition, since the boundary part of light will be formed when the number of LED is made into three or more, it is used suitably.
Moreover, although the color development light of LED is changed from what is arrange | positioned at the upper right, it is not limited to it, It is possible to change from arbitrary directions.
Moreover, although LED is arrange | positioned at the staircase shape which goes up to the right, it is not limited to it, All the LEDs or a part of LED may be arrange | positioned on a horizontal line, a vertical line, a diagonal line, an arc, etc. If the LEDs are arranged with a two-dimensional deviation such as an arc, a diagonal line, or a staircase shape, the display can be spatially expanded.
Moreover, in this embodiment, although the translucent part is arrange | positioned corresponding to LED, it is not limited to it, The arrangement | positioning of a translucent part and LED may shift | deviate. For example, even when the LEDs are arranged on a horizontal line and a vertical line, if the translucent part is arranged with a two-dimensional shift, the display can have a spatial spread.

In the present embodiment, concentric triple circles and circles are formed on the transmission sheet 85 as the translucent part. However, the present invention is not limited to these shapes, and may be any shape such as a polygon, a similar shape, or a plurality of straight lines. The translucent part may be formed in the shape of
For example, a plurality of contours may be formed so as to surround the periphery of the center, and the contour may be formed not only by a circle but also by a polygon or an arbitrary shape. Further, the contour is not continuous but may be discontinuous or discontinuous, and a large contour may be gradually formed in the radial direction from the center. These may be formed in a plurality, for example, in a step shape, and these may be continuously connected. Moreover, you may make it permeate | transmit light not only in an outline but in the whole or a part of the part enclosed by the outline.
Further, although the concentric triple circles are arranged in the upward direction, they may be arranged in an arbitrary manner such as in the upward direction.

  In the present embodiment, the size of the light transmitting portion on the transmission sheet 85 is larger as it is in the upper right. However, the size is not limited to this, and the light transmitting portion is gradually increased along an arbitrary direction such as up and down or left and right. You may change the size of. If the light-transmitting portion is formed so as to gradually increase along one direction, the user (user) can easily understand the direction of change.

  As described above, the embodiments of the present invention have been described. However, the present invention is not limited to such contents, and various modifications can be made without departing from the spirit of the invention.

As described above, in the display device of the present invention, when various types of information are displayed by changing the display color, a change in display color or light intensity is continuously displayed without using a complicated mechanism. Is possible.
Further, when the display device of the present invention is used to display the air condition of the air conditioner, the air condition is not displayed discretely and stepwise, but continuously, so that the human sensory Display becomes possible, and the operation of the air purifying function can be appropriately recognized without giving a sense of discomfort to the user (user).
