Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an indoor unit of an air conditioner, and more particularly to the design and display of an air conditioner.
[0002]
[Prior art]
The indoor unit of the air conditioner is composed of a box body formed of resin that forms the rear part of the indoor unit, a decorative cover body that forms the front part of the indoor unit, and a blow-out unit that forms the lower surface part of the indoor unit Has been. The box body has built-in heat exchangers, blowers, and other equipment that are functional parts of the air conditioner. The decorative cover body has a front grille that sucks room air from the front and the interior from the top. Upper air suction grilles for sucking air are provided, and air filters are accommodated corresponding to the grills. Also, a blow-out air passage that circulates indoor air whose temperature and humidity are harmonized by a heat exchanger is configured, and a wind direction deflecting plate that deflects the flow of the wind is provided near the blow-out opening of the blow-out air passage. . The indoor air sucked into the indoor unit from the front grill at the front and the upper air suction grill at the top is dedusted and dust removed by the air filter, conditioned by the heat exchanger, and blown by the blower. It is sent out into the road, the flow of wind is deflected by the wind direction deflecting plate, and it is blown out into the room again from the outlet.
[0003]
The indoor unit of the air conditioner is installed at a high place near the ceiling of the wall of the room, and harmonizes the indoor space where people live in a comfortable living environment with air that harmonizes the temperature and humidity blown from the high place. It will be going. Recent air conditioners can be operated not only in cooling operations, but also in heating operations, dehumidification operations, and air blows in addition to cooling operations. There are various operation modes such as operation, heating and dehumidifying operation, and timer ON / OFF and air cleaning operation are incorporated, and the function of the air conditioner has been extended to multiple functions.
[0004]
However, since the indoor unit of the air conditioner is installed at a high place near the ceiling of the indoor wall, even if the operation mode display part is provided on the surface of the indoor unit and the operation mode is displayed in characters, it is difficult to see and is not very effective. As a result, it is common for indoor units to have only a few indicator lamps (light-emitting diodes) that can tell whether the power is on or whether the timer mode is operating. .
[0005]
In JP-A-7-63368 (Reference 1), an operation display is provided between the air outlet provided at the lower part of the indoor unit and the air inlet provided at the upper part thereof, near the center in the unit width direction. It is described that a display unit for performing the above is provided.
Also, in order to harmonize the latest indoor unit with the furniture and furniture of the room where the indoor unit is installed, it is no longer necessary to provide an air inlet on the surface of the indoor unit, or the surface panel is a simple plate with no irregularities. The structure of the air conditioner's indoor unit has been finished to make it look like a furniture as much as possible to soften the image of home appliances. Therefore, the display section of the operation mode is omitted from the appearance of the indoor unit, and a display that shows the main operation status of the indoor unit, for example, whether the indoor unit is turned on, etc. with few display lamps. .
[0006]
On the other hand, in order to finish the exterior of the indoor unit as much as possible, the air suction port provided in the front panel as described above was abolished to make the front panel a flat appearance with less unevenness. The air inlet is collectively provided at the upper part of the indoor unit.
[0007]
However, in order to effectively use the heat exchanger incorporated in the indoor unit, as described in JP 2001-41561 A (reference 2) and JP 2001-41489 A (reference 3), It is effective to provide an air suction port on the front panel on the front surface of the indoor unit and send the room air to the heat exchanger incorporated in the indoor unit. For this reason, the height of the air inlet provided on the front panel on the front of the indoor unit is reduced so that when the indoor unit is looked up from the living space where the indoor unit is installed, the air inlet is invisible from the line of sight. Has been made.
[0008]
[Problems to be solved by the invention]
However, the indoor unit of the air conditioner described in Document 2 and Document 3 described above has a heat exchange efficiency in spite of the front panel having a flat appearance without unevenness in order to improve the design of the front surface of the indoor unit. The air inlet is provided on the front for the reason of improving the air quality, and the front air inlet is entirely emphasized instead.
[0009]
In addition, the display unit indicating the operating state of the air conditioner described in Document 1 is particularly arranged because a light source such as a light emitting diode is covered with an exposed or transmissive cover near the center of the front surface of the indoor unit. When the air conditioner is not in operation, the design is designed to make the user aware that there is a display unit there.
[0010]
An object of the present invention is to provide an air conditioner having an air suction port and an operation display unit on the front surface of an indoor unit, although these air presence ports and an operation display unit are provided on the front surface of the indoor unit. It is to harmonize the indoor unit without feeling uncomfortable with the furniture and furniture of the room where the indoor unit is installed.
[0011]
[Means for Solving the Problems]
The object is to provide an air conditioner that includes a heat exchanger and a blower housed inside an indoor unit, sucks air from an air suction port, and blows air from a blow-out unit on the bottom surface. The front air inlet provided in the direction, and the back of the air passage that has a concave cross section so that it goes from the inlet to the back as it goes from the bottom to the top of the front air inlet, and is arranged over the entire width of the inlet A wall, and an operation mode display unit front cover that is formed at a lower portion of the rear wall of the air passage and is formed in front of the front suction port on the front surface of the indoor unit and has a display light source on the rear surface. This is achieved by configuring the back wall and the front cover of the operation mode display unit with a translucent plate made of a material capable of transmitting light.
[0012]

In FIG. 4, 6 is a decorative plate (translucent plate), 6a is an air channel inner wall, 6b is an operation mode display unit, 16 is a reflector, 17 is a light emitting window, and 18 is a light emitting device.
[0014]
The indoor unit of the air conditioner in the present embodiment is configured as follows. That is, as shown in FIGS. 1 and 2, the indoor unit is composed of a box body 1, a decorative cover body 2, and a blowout unit 3, and the box body 1 includes a plurality of divided heat exchangers 9 and 9. Although not clearly shown in the figure, the air blower 10 is incorporated with other refrigeration cycle components, electrical components, and the like. In addition, a front panel (front panel) 4 composed of a flat surface with no surface irregularities is incorporated in the front portion of the decorative cover body 2 in order to improve the appearance of the exterior design of the indoor unit. An upper air suction panel 7 for sucking room air is incorporated. An air filter 8 is detachably attached to the inside facing the front panel 4 and the upper air suction panel 7 by sliding the slide groove of the decorative cover body 2.
[0015]
Further, as shown in FIG. 2, a lower air suction port 5 and a decorative plate (translucent plate) 6 are provided at the lower portion of the front panel 4. The lower air suction port 5 is provided over a substantially entire length of the front panel 4 with a small height. A decorative plate (translucent plate) 6 provided at the lower portion of the lower air inlet 5 has the same width as the lower air inlet 5 and a portion excluding the air channel inner wall 6a (formed with a curved surface with a gentle cross-sectional shape). The height dimension of the portion extending on the lower extension surface of the front panel 4 is made substantially the same height, and functions as two accents that flow laterally at the lower portion of the front panel 4. The width of the portion of the lower air inlet 5 and the decorative plate (translucent plate) 6 except for the air channel inner wall 6a is the same, and the height is almost the same. And the lower air inlet 5 is configured to be difficult to recognize as an opening for sucking room air.
[0016]
Furthermore, the operation mode of the air conditioner is intended to be displayed by the difference in the color tone of the light emitting body provided in the operation mode display unit 18 without impairing the appearance design of the indoor unit. Therefore, an air suction port having a small height is provided over the entire width of the front panel 4 on the front surface of the indoor unit 1 to ensure a flat flat surface portion (curved surface portion) of the front panel 4. A decorative plate (translucent plate) 6 having the same height as that of the air suction port 5 that functions as an accent of the appearance design of the indoor unit 1 is provided below the air suction port having a reduced height. In addition to making the exterior of the indoor unit 1 have a mild atmosphere, a display lamp that can emit light in several colors is provided on the back of a decorative plate (translucent plate) 6 that can transmit light, and the operation mode of the air conditioner is more detailed. Can be displayed.
[0017]
However, since the decorative plate (transparent plate) 6 is made of a material that can transmit light, the mounting leg when the decorative plate (transparent plate) 6 is incorporated into the decorative cover body 2 is the decorative plate (transparent plate). From the surface, it becomes visible as a difference in color tone, and as a new problem, it is necessary to prevent the mounting leg from being seen as a difference in color tone from the surface of the decorative board (translucent plate) 6.
[0018]
As shown in FIG. 3, the upper half of the decorative plate (translucent plate) 6 constituting the lower end surface of the lower air suction port 5 is raised upward so as to draw an arc, and the air channel inner wall 6a is The lower suction air passage 5a is formed at a slight distance from the front panel 4 that forms the upper end surface of the lower air suction port 5. Since the air channel back wall 6a is separated from the front panel 4 by a small distance, even when the indoor unit is looked up from the living space of the room, the air channel back wall 6a in the back is not the opening of the lower air suction port 5. The lower air inlet 5 is less likely to be recognized as an opening.
[0019]
Further, since the decorative plate (translucent plate) 6 is made of a material that can transmit light, when the indoor unit is looked up from the living space, not the lower air suction port 5 but the decorative plate (translucent plate) 6 Devised to gather. Since the air passage back wall 6a integrated with the decorative board (translucent plate) 6 is also made of a material that can transmit light, light incident on the inside of the air passage back wall 6a from the surface of the air passage back wall 6a When the light is reflected from the back surface and returns to the front side of the air passage back wall 6a, the air passage back wall 6a itself is slightly lit by illuminating the inside of the air passage back wall 6a. Therefore, the line of sight looking up at the indoor unit is poured from the lower air inlet 5 into the air passage inner wall 6a, and the lower air inlet 5 is less likely to be recognized as an opening as an air inlet. Therefore, the lower air suction port 5 is less recognized as an opening, and visually forms a flat surface with less unevenness of the front panel 4 together with the decorative plate (translucent plate) 6 below it. It becomes possible to harmonize with furniture and furniture in the room where the indoor unit is installed without a sense of incongruity.
[0020]
As shown in FIG. 2, the lower half portion of the decorative plate (translucent plate) 6 also serves as the operation mode display unit 6 b that displays the operation mode of the air conditioner, and the lower air inlet 5 and the blowout air path 12. Function to prevent the shortcut circuit that is directly sucked from the lower air intake port 5 by forming a shortcut circuit without circulating through the indoor space, while keeping the distance of the air and the temperature and humidity conditioned from the blowout air passage 12 harmonized. Also plays.
[0021]
When the indoor unit is turned on and the air conditioner is operated, the blower 10 rotates and sucks indoor air from the lower air inlet 5 and the upper air inlet panel 7 into the indoor unit. The dust and the dust are removed, and the plurality of heat exchangers 9 are used to remove the dust and the dust to harmonize the temperature and humidity of the room air. The conditioned room air flows through the blower 10 and is sent to the blowout air passage 12. The airflow is deflected by the left and right wind direction deflecting plates 13 and the upper and lower air direction deflecting plates 14 to remove dust and dirt. It is blown out to every corner of the room as temperature and humidity harmonized air. By repeating this flow of indoor air, the indoor space is harmonized with a comfortable state for people to live.
[0022]
Although not described in detail in the present embodiment, the front panel 4 is pivotally mounted with a pivot shaft provided at a lower portion of the front panel 4 as a support shaft. Thus, the front panel 4 can be opened from the decorative cover body 2, and the front panel 4 can be detached from the decorative cover body 2. Further, the air filter 8 can be removed by sliding the groove of the decorative cover body 2 by rotating the front panel 4.
[0023]
Also, on the lower surface of the indoor unit 1, a blowing unit 3 having a blowing air passage 12 incorporating a left and right wind direction deflecting plate 13 and an up and down wind direction deflecting plate 14 is attached to the box body 1 via a hinge 15 so as to be rotatable. It has been. When the air conditioner stops operation, the up / down wind direction deflecting plate 14 functions as an exterior design part at the position a in FIG. 2, and when the air conditioner is in operation, the position shown in FIG. The flow in the vertical direction of the harmonized room air blown out from the blowout air passage 12 in b is deflected. Although not explicitly shown in the present embodiment, the lower surface of the indoor unit can be opened by rotating the blowout unit 3 around the hinge 15 as a support shaft, so that it is incorporated into the blowout air passage 12 and the blowout unit 3. The left and right wind direction deflecting plates 13 and the up and down wind direction deflecting plates 14 can be easily cleaned. Further, the blower 10 exposed in the open space can be easily cleaned from the space opened in the lower part of the indoor unit.
[0024]
In this embodiment, as shown in FIG. 3, since the lower air suction port 5 is provided at the lower part of the front panel 4, the indoor air sucked from the lower air suction port 5 is as shown by a streamline A indicated by a one-dot chain line. It flows and spreads in the lower half part of the heat exchanger 9a to exchange heat with the heat exchanger 9a. In the upper half of the heat exchanger 9a, a streamline B which is a flow of indoor air sucked from the upper air inlet 7 flows, and indoor air flows over the entire surface of the heat exchanger 9a. It can be used effectively. However, if the lower air inlet 5 is not provided with an emphasis on the aesthetic appearance, the streamline A that is the flow of room air that the lower air inlet 5 sucks disappears. Therefore, in the heat exchanger 9a, the indoor air sucked from the upper air suction port 7 flows only in the upper half of the heat exchanger 9a, and sufficient room air is in the lower half of the heat exchanger 9a. Since it does not flow, the heat exchanger 9a cannot be used effectively.
[0025]
Further, in order to maintain the aesthetic appearance of the indoor unit 1, the front panel 4 is divided into upper and lower parts, and when the indoor unit is looked up from the living space, a lower air suction port 5 is provided at a position behind the divided front panel 4. There is a method of making the lower air inlet 5 invisible. Also in this case, since the front panel 4 is divided and the lower air inlet 5 is provided, the lower air inlet 5 is provided in a relatively upper part of the front panel 4, so that the lower part of the heat exchanger incorporated in the indoor unit is below. The room air cannot be sufficiently guided to the half, and the heat exchanger cannot be used efficiently.
[0026]
However, in this embodiment, since the lower air inlet 5 is provided directly in the lower part of the front panel 4, the indoor air is sufficiently guided to the lower half of the heat exchanger 9a incorporated in the indoor unit, and the heat exchanger 9a is installed. It can be used effectively. However, although the heat exchange efficiency of the heat exchanger 9a can be improved by providing the lower air suction port 5 directly on the lower surface of the front panel 4, there is a problem that the appearance design of the indoor unit is impaired. In order to solve this problem, in this embodiment, as described above, the lower air suction port 5 is made thin and long so that the appearance design is not conspicuous. Furthermore, by providing a decorative plate (translucent plate) 6 formed of a material that transmits light below the lower air suction port 5 in the same thin and long shape as the lower air suction port 5, a line of sight looking up at the indoor unit can be obtained. The lower air suction port 5 attracts the decorative plate (translucent plate) 6 so that the line of sight is not poured into the lower air suction port 5.
[0027]
In FIG. 4, the decorative plate (translucent plate) 6 is further formed of a material that allows light to pass therethrough, so that the air passage back wall 6a that forms a part thereof can also transmit light, and the air passage back wall 6a. The light incident from the surface of the air is reflected on the back surface of the decorative plate (translucent plate) 6 and returns to the surface of the air channel inner wall 6a, and is emitted from the surface of the air channel inner wall 6a into the room, thereby The wall 6a itself appears to emit light faintly. For this reason, the line of sight poured into the lower air suction port 5 is concentrated on the air passage inner wall 6a, and the lower air suction port 5 as an opening is not conscious. Since the lower air inlet 5 is not recognized as an opening, the indoor unit can be harmonized with the furniture and furniture of the room without a sense of incongruity.
[0028]
Detailed configurations of the decorative plate (translucent plate) 6 and the light emitting device 18 are as shown in FIGS. That is, the decorative board (translucent board) 6 is formed by the previously described airway wall 6a and the operation mode display section 6b (this operation mode display section 6b constitutes a front cover of a light emitting source such as a light emitting diode). Has been. And the operation mode display part 6b has a function which prevents the shortcut circuit of the air which blows off from an indoor unit, and the operation mode display function which displays the difference in an operation mode by the difference in the color tone of a light-emitting body. A reflective plate 16 is provided over the entire back side of the decorative plate (translucent plate) 6, and a light emitting device 18 is provided behind the operation mode display unit 6 b.
[0029]
As shown in FIG. 5, the decorative plate (translucent plate) 6 is provided with a mounting leg 23a at the distal end portion of the air passage inner wall 6a, and further, a projection 23c is provided at the distal end portion. The operation mode display portion 6b is also provided with a mounting leg 23b at the tip thereof, and an engagement hole 23d is provided in the mounting leg 23b. Then, the engagement hole 23d provided in the mounting leg 23b of the operation mode display portion 6b is engaged with the protrusion 2b provided in the decorative cover body 2, and provided at the tip of the mounting leg 23a of the air passage back wall 6a. The decorative plate (translucent plate) 6 can be incorporated into the decorative cover body 2 by engaging the protrusions 23 c with the engagement holes 2 a provided in the decorative cover body 2.
[0030]
At this time, the reflecting plate 16 is fixed to the rear portion of the decorative plate (transparent plate) 6 by the reflective plate support column 2 c provided on the decorative cover body 2 and the decorative plate (transparent plate) 6.
[0031]
The light incident on the decorative plate (translucent plate) 6 is reflected and refracted as shown in FIG. That is, the light a and b incident from the surface portion other than the mounting leg 23 is partially reflected as a ′ and b ′ on the surface of the decorative plate (translucent plate). Then, the light incident on the interior of the decorative plate (transparent plate) 6 is refracted at the surface portion, reaches the back surface of the decorative plate (transparent plate) 6, is reflected on the rear surface, and is again reflected on the decorative plate (transparent plate) 6. Radiated from the surface as a ″, b ″. Even when reflected on the back surface of the decorative plate (translucent plate) 6, some light passes through the back surface and penetrates through the decorative plate (transparent plate) 6 like a ′ ″ and b ′ ″. Eventually, the means for reducing the amount of light penetrating the back surface of the decorative plate (translucent plate) 6 is the hairline processing applied to the back surface of the decorative plate (transparent plate) 6. Surface. The reflecting plate 16 is a means for reflecting the light that has penetrated and returning it to the decorative plate (translucent plate) 6 and radiating it again from the surface of the decorative plate (translucent plate) 6.
[0032]
Since the operation mode display unit 6b is also made of a light-transmitting material like the air passage back wall 6a, the light incident from the surface of the operation mode display unit 6b is reflected on the back of the operation mode display unit 6b and is operated in the operation mode. It returns to the surface side of the display part 6b, and is radiated | emitted indoors from the surface of the operation mode display part 6b. Then, like the air channel inner wall 6a, the operation mode display unit 6b itself appears to emit light by the light incident on the operation mode display unit 6b. Further, the back side of the decorative plate (translucent plate) 6 is not flat but is subjected to fine slits such as hairline processing or fine unevenness such as sandblasting as shown in FIGS. The light that has entered the interior of the decorative plate (translucent plate) 6 is scattered at a wider angle by fine slits and fine irregularities on the back side, and is emitted from the surface of the decorative plate (translucent plate) 6 Since the light to be spread also spreads over a wide angle, the image of the decorative board (translucent board) 6 becomes softer, and the indoor unit can be harmonized with the furniture and furniture of the room without a sense of incongruity.
[0033]
The reflective plate 16 provided over the entire back side of the decorative plate (translucent plate) 6 is made of a material that can transmit light in the same manner as the decorative plate (translucent plate) 6. As shown in FIG. A coating 16a is applied to the entire surface leaving the light emitting window 17.
[0034]
That is, as described above, the light entering from the outside of the decorative board (translucent board) 6 formed of a transparent resin (in this embodiment, colorless and transparent) reflects itself and is attached to the back and colored. The applied reflector 16 is also reflected and returned to the outside. At this time, the color of the light entering the eye is the color of the reflecting plate 16. For this reason, the interior of the indoor unit is not visible from the outside. On the other hand, the reflecting plate 16 also has an effect like a lamp shade made of Japanese paper. Japanese paper lamp shades soften the light of the lamp, which is an internal light source, and prevent the inside lamp and lamp socket from being seen from the outside. The reflecting plate 16 of the present embodiment is also formed of a sheet-like resin, and is expected to have the same effect as the lamp shade. For this reason, lamps such as light emitting diodes inside the indoor unit and other parts are not easily seen from the outside, and the effect of the fine unevenness provided on the back surface of the decorative board (translucent board) 6 is combined. The light indicating the operating state from the display 18 is made light and behaves as if the entire decorative board (translucent board) 6 is one soft light emitter.
[0035]
In FIG. 6, a plurality of light emitters 20 of the light emitting device 18 are provided corresponding to the plurality of light emission windows 17. By providing a plurality of light emitting windows 17 for displaying the operation mode on the reflecting plate 16, the operation mode display section is indirectly viewed through the decorative plate (translucent plate) 6, and the light emitting window 17 can be viewed from the exterior of the indoor unit. Since it was not visible directly, the whole indoor unit can be wrapped in a peaceful atmosphere.
[0036]
Further, in the light emitting window 17a that is the center of the light emitting window 17, the color tone of the light emitting body 20 that emits light from the same light emitting window 17a is changed, and more operation modes are expressed by fewer light emitting windows 17. As shown in FIG. 7, the light is emitted from a plurality of light emitting bodies 20 having different emission colors to a main light emission window 17a, and light is emitted from the light emission window 17a using a long prism 21. ing. As shown in FIG. 7, the light emitting device 18 incorporates a light emitting body 20 such as an LED with a long prism 21 sandwiched on a substrate 19. The substrate side of the long prism 21 has fine irregularities on the surface so that the light guided into the long prism 21 can be effectively emitted through the light emission window 17a. Further, on the back side, a prism reflector 21 is incorporated which reflects light leaking from the long prism 21 and increases the amount of light emitted from the surface of the long prism 21.
[0037]
In the light emitter 20 provided so as to sandwich the long prism 21, for example, a blue light emitter is used as the light emitter 20a, a red light emitter is used as the light emitter 20b, and a green light emitter is used as the light emitter 20c. The light guided from the end surface portion of the long prism 21 is refracted and reflected by the minute unevenness on the back surface portion of the long prism and the prism reflection plate 22 toward the light emission window 17a, and is emitted from the surface of the long prism 21 to be reflected. The light passes through the light emission window 17a of the plate 16 and is emitted to the surface of the indoor unit through the operation mode display unit 6b. At this time, if the blue light emitter 20a emits light according to the emission color of each light emitter 20, the cooling operation is displayed, and if the red light emitter 20b emits light, the heating operation is displayed. It is determined that the dehumidifying operation is displayed when the body 20c emits light. When determining the color tone and the operation mode, it is not necessary to remember the combination of the color tone and the operation mode by matching with the operation mode generally imaged from the color tone, and the light emission emitted from the operation mode display unit 6b. The operation mode can be identified by the color tone of the body 20. For example, in this embodiment, blue is used for the cooling operation, red is used for the heating operation, and green is used for the dehumidifying operation. Even if it is installed at the height of the wall surface of the room, it becomes possible to easily recognize the operation mode by the emission color.
[0038]
Further, as shown in the light emission window 17a of FIG. 6, the on / off of the power supply of the air conditioner is displayed depending on whether or not the light emitter emits light, and the operation mode is displayed by the color tone of the light emitter 20 that emits light at that time. Thus, the difference between the on / off display of the power source and the operation mode can be performed by the same light emission window 17a. Since the number of the light emission windows 17 can be reduced by combining the light emission of the light emitter 20 and the difference in the light emission color, the display portion of the operation mode can be limited to a narrow range, and the appearance of the indoor unit appearance can be improved. become. As a result, a plurality of operation modes can be displayed on one light emitting window 17, and a more complicated operation mode can be displayed by combining with other light emitters 20.

However, the color difference is eliminated, and the appearance of the exterior surface of the decorative board (translucent board) 6 is not impaired. This also applies to the operation mode display portion 6b, and the difference in color between the mounting leg 23 portion and the portion without the mounting leg 23 is eliminated, and the appearance of the appearance surface of the operation mode display portion 6b is not impaired.
[0044]
In addition, as shown by the two-dot chain line in FIG. 10, a method of covering the color difference between the mounting leg 23 and the portion without the mounting leg 23 by providing the mounting cover shielding parts 2 d and 2 e on the decorative cover body 2 is also conceivable. In this case, the mold for manufacturing the decorative cover body 2 becomes complicated, the mold cost increases, and the product price increases. Moreover, since the decorative board (light-transmitting board) 6 is incorporated into the interior of the decorative cover main body 2 narrowed by the mounting leg shielding portion 2d from the assembling work surface, the assembling workability is deteriorated and the price of the product is increased accordingly. Will do.
