Definitions

  • the present invention relates to an indoor unit of an air conditioner capable of improving the design quality of the front side of an indoor unit body.
  • a housing serving as the body of the indoor unit includes a front portion constituted by a front frame, a front panel, and a display cover, and a rear portion constituted by a base frame.
  • the front panel is attached to the front frame, and serves as a design surface.
  • the display cover is attached to a lower portion of the front panel to extend in lateral directions from the center in the width direction thereof, and serves as a display member.
  • the baseframe houses a heat exchanger, an air blower, and so forth.
  • the display cover is formed of a transparent or translucent synthetic resin allowing the transmission therethrough of light, and is fixed to the front panel by a wedge member. Further, the display cover is provided with a plurality of display portions on the outer surface (the front surface) or the inner surface (the back surface) thereof. The display portions are laterally provided by printing or the like and highlighted by light applied from the back side. Further, a word or phrase explaining the content of the information displayed by each of the display portions, e.g., letters such as OPERATION, TIMER, INTERNAL CLEANING, HUMIDITY, OUTDOOR, FILTER, ODOR, VENTILATION, and DUST, is printed at a position above the vicinity of the display portion on the front surface.
  • letters such as OPERATION, TIMER, INTERNAL CLEANING, HUMIDITY, OUTDOOR, FILTER, ODOR, VENTILATION, and DUST
  • a light-emitting device such as an LED (light-emitting diode) is provided to be located on the back side of the display cover. As the light emitted from the light-emitting device is transmitted through the display cover, the respective display portions printed on the display cover and the contents of the corresponding display information are selectively illuminated to highlight corresponding information (patent documents No.1, for example).
  • Patent Documents No.1 Japanese Unexamined Patent Application Publication No. 2005-147432 ( Figs. 2 to 4 ).
  • Such an issue can be overcome by, for example, providing a half-mirror film to a surface of the display to make the shape of the display invisible in the light-off state of the light-emitting device.
  • a half-mirror film to make the shape of the display invisible in the light-off state of the light-emitting device.
  • the half-mirror imposes another design constraint.
  • the dominant color of the indoor unit is white in accordance with the color of the wallpaper of a room.
  • the half mirror which is similar to a mirror surface, conversely emphasizes the presence of the indoor unit.
  • the front surface includes a curved portion, an object reflected by the half mirror appears in a larger or smaller size than the original size thereof, and thus the presence of the indoor unit is further emphasized.
  • the front surface can be formed only by a flat surface.
  • the design surface on the front side is constituted by two components, i.e., the front panel and the transparent or translucent display cover attached to the front panel and provided with the display portions.
  • This structure is disadvantageous in that the design surface includes a dividing line, which constitutes another significant design constraint.
  • An indoor unit of an air conditioner has the following configuration. That is, the indoor unit of an air conditioner includes a front panel and a display portion positioned at a front portion of an indoor unit body.
  • the front panel is openable and closable.
  • the display portion includes a light-emitting device controllable in the lighting on and off thereof, and is provided inside the indoor unit body to face the front panel, to display operation information such as an indoor state or an operation setting state.
  • the front panel is formed of a transparent or translucent material, and is provided with a decorative layer on the inner or outer surface thereof or inside thereof.
  • the decorative layer has non-reflectivity, allows the transmission therethrough of light emitted from the light-emitting device, and prevents the interior of the indoor unit body from being seen through from outside of the indoor unit in a light-off state.
  • the front panel is formed of the transparent or translucent material. Further, on the inner or outer surface of the front panel or inside the front panel, the non-reflective decorative layer is provided which allows the transmission therethrough of the light emitted from the light-emitting device, but which prevents the interior of the indoor unit body from being seen through from outside of the indoor unit in the light-off state. In the light-off state of the light-emitting device, therefore, any depiction relating to the display portion is not shown on the front surface of the front panel. So, display contents are depicted on the front surface of the front panel only after the light-up of the light-emitting device. Accordingly, a design constraint imposed by the display contents is eliminated, and the degree of design freedom is increased.
  • a housing of an indoor unit body 1 includes a front portion constituted only by a front frame 3 and a front panel 2 which is attached to the front frame 3 to be openable and closable with respect thereto and serves as a design surface, and a rear portion constituted by a base frame 6 for housing a heat exchanger 4, an air blower 5, and so forth.
  • the front panel 2 is formed of a transparent or translucent material including an ABS (acrylonitrile butadiene styrene) resin having high chemical resistance and insolubility in by a paint and so forth. If the outer surface (the front surface) or the inner surface (the back surface) of the front panel 2 is not provided with anything, an object can be seen through the front panel 2, i.e., the interior of the indoor unit body 1 can always be seen through. As illustrated in Figs. 2 to 4 , however, the front panel 2 is provided with a decorative layer 10, which is homogeneously painted or printed on the entire area (the entire surface) of a back surface of the front panel 2, and which has low reflectivity and a color of high brightness, such as white and beige. Accordingly, the interior of the indoor unit body 1 cannot be seen through from outside of the indoor unit. However, light emitted from inside the indoor unit body 1 can be transmitted through the decorative layer 10, as described later.
  • ABS acrylonitrile butadiene styrene
  • the decorative layer 10 is formed into a thickness of 20 ⁇ m or more. If the decorative layer 10 is formed into a thickness of less than 20 ⁇ m, the interior of the indoor unit body 1 is seen through. That is, the thickness of 20 ⁇ m or more of the decorative layer 10 is a minimum thickness necessary for preventing the interior of the indoor unit body 1 from being seen through from outside of the indoor unit.
  • the upper limit of the thickness of the decorative layer 10 slightly varies depending on the color of the employed paint and so forth. Irrespective of the color to be employed, however, it is needless to say that the upper limit is set to a thickness allowing the light emitted from a light-emitting device 9 described later to be transmitted through the decorative layer 10.
  • the decorative layer 10 may alternatively be provided on the front surface of the front panel 2.
  • the thickness of the front panel 2 it is necessary to prevent the flowing direction of the resin from being generated as a line in a molding process, and to make the resin easily flow.
  • each of the lateral ends of the inner surface of the front panel 2 is equipped with a front panel holder 13, which is provided with a support arm 11 and a locking clamp 12 for attaching the front panel 2 to the front frame 3, to prevent the portions shaped for fixation from being seen from outside of the indoor unit.
  • portions of the front panel 2 to install the front panel holders 13 have also been previously provided with the decorative layer 10 such that the presence of the front panel holders 13 at the portions is hidden from outside of the indoor unit.
  • the color of the front panel holders 13 may be made the same as the color of the decorative layer 10.
  • the front panel 2 is fixed to the front frame 3 via the support arm 11 and the locking clamp 12 provided to each of the front panel holders 13, and can be attached to and detached from the front frame 3 and opened and closed with the support arm 11 functioning as a fulcrum.
  • the light-emitting device 9 is mounted on a display board 14.
  • a white LED light is employed as the light-emitting device 9.
  • the display board 14 is held by a display board fixing member 15.
  • the display board fixing member 15 includes display windows 16 each formed into a shape desired to be depicted in the light-on state of the light-emitting device 9. As illustrated in Fig. 4 , in the closed state of the front panel 2, the display board fixing member 15 is constantly biased forward by a coil spring 17 disposed on the back side thereof, and the display windows 16 are made in close contact with and fixed to the decorative layer 10 of the front panel 2.
  • each of the display windows 16, i.e., the size of a word or phrase or a pictogram displayed on the surface of the front panel 2 needs to be 4 mmx4 mm or more for visibility.
  • the upper limit of the size is preferred to be set to 50 mmx50 mm or less, i.e., a size not excessively large in terms of design. Accordingly, display contents can be easily recognized, and an area provided with a necessary number of the display contents can be easily secured. Further, the shape of each of the display windows 16 determines the shape to be displayed. Therefore, a highly accurate window shape can be easily obtained.
  • a switch capable of changing the illuminance of the display portion and turning off the light is provided to the indoor unit body 1 or a remote controller (not illustrated) of the air conditioner. Accordingly, it is possible to turn off the light of the display portion at bedtime in the nighttime, for example, and thus to prevent the light from disturbing the sleep of the user.
  • the present example includes four display contents, i.e., a temperature display 19, a human detection display 20, an energy saving level display 21, and a cleaning display 22.
  • the temperature display 19 displays the set temperature and the sensible temperature actually felt by a person, which is based on the room temperature, the humidity, and the temperature of the walls and floor, at intervals of 0.5°C in accordance with the situation at a given time.
  • the room temperature may be displayed instead of the sensible temperature.
  • the intervals of 0.5°C may be replaced by intervals of 1°C. If the sensible temperature is displayed at the intervals of 0.5°C, subtle display of a temperature close to the temperature actually felt by a person can be provided. Accordingly, temperature setting suitable for the user can be easily performed while viewing the display portion of the indoor unit body 1. As a result, the comfort is improved.
  • the human detection display 20 displays the position and the range of activity of a person detected by an infrared sensor 50 provided to the indoor unit body 1. Accordingly, the user can visually understand the operational state of the indoor unit. Further, the indoor unit may be provided with a function of detecting the position and the range of activity of a person through the infrared sensor 50 and automatically changing the wind direction on the basis of the information obtained from the detection, and to use the human detection display 20 for displaying the wind direction. In this case, the user can visually understand the operational state of the indoor unit.
  • the energy saving level display 21 displays the level of energy saving by the number of leaves. The greater number of the leaves indicates the higher energy saving level. Further, the energy saving level can be set by the remote controller, and is changed depending on whether or not each of the temperature of the walls and floor, the position of a person, and the amount of activity of a person is activated. Accordingly, the energy saving level can be checked while viewing the display portion of the indoor unit body 1.
  • the cleaning display 22 is lighted up in an automatic cleaning operation of a filter and a drying operation of the heat exchanger 4.
  • the above-described display portion normally displays the current state of inside of the room. However, after the setting is changed, it is configured to display only a changed content of the setting for only a predetermined time. That is, upon a change in the set temperature, the temperature display 19 is lighted up and displays the changed set temperature for a predetermined time. Further, upon a change in the energy saving level, the energy saving level display 21 is lighted up and displays the changed energy saving level for a predetermined time. Accordingly, the changed contents can be checked while viewing the display portion of the indoor unit body 1.
  • the color of the light-emitting device 9 is all white to make the color of the decorative layer 10 appear to the front, and to unify the color of the light emitted from the light-emitting device 9.
  • the color appearing to the front is the mixture of the two colors.
  • the intended color (the color of the decorative layer 10) can be obtained, and the design is simplified.
  • the intended color (the color of the decorative layer 10) can also be obtained by using the light-emitting device 9 capable of creating the same light color as the color of the decorative layer 10.
  • the white light color and the white decorative layer 10 were employed, a display with a highest-class feeling was obtained.
  • the color appearing to the front does not necessarily need to be unified.
  • the color may be changed in accordance with the display content to permit visual distinction between the display contents, as in a case in which the energy saving level display 21 is displayed in a green color, for example.
  • any depiction relating to the display portion is not shown on the front surface of the front panel 2, and only the decorative layer 10 is visible. Therefore, the presence of the display portion is unnoticed.
  • the light-emitting device 9 If the light-emitting device 9 is lighted up, the generated light is transmitted through the display windows 16 and further through the decorative layer 10, as illustrated in Fig. 6 .
  • the emitted light appears to have the shapes of the display windows 16, as viewed from the front side.
  • the display board fixing member 15 is biased forward by the coil spring 17, and the display windows 16 are in close contact with and fixed to the decorative layer 10 of the front panel 2.
  • a clearance allowing the leakage and spread of the light does not exist between the decorative layer 10 and the display windows 16. Therefore, the outline (the display shape) of each of the display windows 16 is distinctly displayed without being obscured.
  • the temperature display 19 displays the sensible temperature based on the room temperature and the humidity. If the energy saving level is increased by one level with the use of the remote controller, the temperature display 19 shifts to the display of the sensible temperature further in consideration of the radiant heat from the walls and floor and so forth. Further, if the temperature of the floor is low in a cooling operation, the operation frequency is reduced to perform an energy saving operation, and one of the leaves of the energy saving level display 21 is lighted up.
  • the human detection display 20 displays the position and the range of activity of a person. If the energy saving level is increased by one level with the use of the remote controller, wind is sent to the location of the person in consideration of his position, and the air-conditioning is not performed in an area in which a person is absent. Thereby, the energy saving operation is performed, and another one of the leaves of the energy saving level display 21 is lighted up. If the energy saving level is further increased by one level, the amount of activity of a person is taken into consideration. Then, if the amount of activity is small, and if the cooling operation is being performed, the set temperature is slightly raised to perform the energy saving operation, and another one of the leaves of the energy saving level display 21 is lighted up.
  • the reduction of the illuminance and the turning off of the light can be performed with the use of the switch provided to the indoor unit body 1 or the remote controller of the air conditioner. Accordingly, the issue of the design constraint does not arise.
  • the front panel 2 is formed of the transparent or translucent material, and the back surface of the front panel 2 is provided with the decorative layer 10 by painting or printing.
  • the light-emitting device 9 is lighted up from the back side of the front panel 2 through the display windows 16, and decorative layer 10 prevents the interior of the indoor unit body 1 from being seen through, but allows the transmission therethrough of the light emitted from the light-emitting device 9.
  • any depiction relating to the display portion is not shown on the front surface of the front panel 2, and the display contents can be depicted on the front surface of the front panel 2 only after the light-up of the light-emitting device 9. Accordingly, the design constraint imposed by the display contents is eliminated, and thus an unconstrained design can be obtained.
  • the design surface on the front side is constituted solely by the single front panel 2. Therefore, the dividing line formed by the structure constituted by a plurality of components is not generated, and thus an unconstrained design can be obtained. Further, the number of components is reduced, and thus the costs can be reduced.
  • the decorative layer 10 is formed of the paint having low reflectivity. Therefore, diffuse reflection is not caused by the decorative layer 10. Thus, it is possible to suppress the leakage of the light emitted from the light-emitting device 9 to the outside of the display portion. Accordingly, the front panel 2 can be formed into a curved shape, and the design constraint on the shape of the front panel 2 is eliminated. As a result, the degree of design freedom is increased.

  • the above relationship may be reversed, i.e., the portions having shapes desired to be depicted may be formed by the display sheet 18 which can block light, and the light may be transmitted through the surroundings of the portions.
  • the other parts of the configuration of the present embodiment are similar to those of the first embodiment described above.
  • the display portion is formed by the display sheet 18 capable of blocking light, in which the portions having shapes desired to be depicted have been cut out or left. Accordingly, in addition to effects similar to the effects of the first embodiment described above, the present embodiment can simplify the structure of the display windows 16 and easily obtain minute display shapes.
  • a desired pattern such as a wood-grain pattern and a marble pattern, can be easily depicted.
  • the air conditioner is the electric appliance which consumes the largest amount of electric energy among household appliances. This is attributed to the fact that one air conditioner, which had been installed per household, has been installed per room in recent years. Therefore, the air conditioner is subject to energy regulation under the Energy Saving Law, and technologies for saving energy consumed by the air conditioner are under development.
  • FIG. 8 illustrates an example in which the energy consumption W during the operation of the air conditioner is displayed on the front panel 2 as a energy consumption display 23.
