Hereinafter, each embodiment of the present disclosure will be described with reference to the drawings.

[Air conditioner controller configuration]
Hereinafter, a controller for an air conditioner according to an embodiment of the present disclosure will be described using FIGS. 1 to 8B. In this embodiment, a controller that is fixed to a mounting surface such as a wall of a house and controls an indoor unit of an air conditioner will be described.

As shown in FIG. 1, an air conditioner controller 1 according to the present disclosure is connected to an air conditioner 50 by wire or wirelessly, transmits an operation control signal to the air conditioner 50, and operates the air conditioner 50. It has a function to display the status. The air conditioner 50 may be a ceiling-embedded air conditioner as shown in FIG. 1, for example, or may be a duct type air conditioner (not shown in FIG. 1), and the type of air conditioner is Not limited. The controller 1 is attached to a mounting surface 101 such as an indoor wall surface using a mounting member (not shown) such as a screw or double-sided tape.

FIG. 2 is an external perspective view showing the external configuration of the controller 1. As shown in FIG. As shown in FIG. 2, the controller 1 includes a main body 10 of the controller 1, a screen panel 20, and a light source 151 (not shown in FIG. 2) that irradiates the screen panel 20 with light. Here, FIG. 2 is a configuration example in which the main body portion 10 has a hollow rectangular parallelepiped shape. The light source 151 illuminates the screen panel 20 by emitting light in different colors depending on the operating mode of the air conditioner 50. As a result, the user 102 can visually check whether the air conditioner 50 is in operation or stopped, and which operation mode the air conditioner 50 is in, even if the user 102 is away from the controller 1. It can be confirmed. Therefore, visibility of the operating state of the air conditioner 50 is improved.
Each part of the air conditioner controller 1 will be described in detail below.

<Body part>
As shown in FIG. 2, the main body section 10 includes a rectangular front section 11 in which the display section 14 is arranged, a back section 12 provided on the back surface of the display section 14, and the front section 11 and the back section 12. It has a connecting side portion 13. The back surface 12 is provided with a mounting portion (not shown) that allows attachment to the mounting surface 101. Further, inside the main body portion 10, a circuit board 15 (details will be described later) and the like are arranged.

FIG. 3A is a front view of the controller 1 and shows an example of the display section 14. In FIG. 3, the display section 14 shown in FIG. 2 is shown inverted in black and white for explanation. FIG. 3B is a right side view of the controller 1. Further, FIG. 4 is a cross-sectional view showing the AA cross section of the controller 1 shown in FIG. 3. As shown in FIG. FIG. 4 shows only the parts necessary for explaining the structure of the controller 1 of the present disclosure.
As shown in FIGS. 3B and 4, the main body 10 is composed of a plurality of parts, and the screen panel 20 is held and fixed between the plurality of parts, for example, a case 16 serving as a front case and a base 17 serving as a rear case. do.

(Display)
The display section 14 is exposed, for example, on the front surface section 11 side, and is surrounded by a case 16 that is the exterior of the main body section 10 when viewed from the front. The display unit 14 is a display screen having a liquid crystal screen that has the function of a touch panel operation unit for operating the air conditioner 50 and the function of a display unit for displaying the operating status of the air conditioner 50.
The display section 14 is formed, for example, by overlapping a transparent member 142 such as glass or a half mirror on a liquid crystal display (LCD) 141. By providing the transparent member 142 such as glass or a half mirror, the controller 1 has a high design quality.

As shown in FIG. 3A, the operating state of the air conditioner 50 is displayed on the display unit 14. Large arcs 14A and 14B in the center of the display section 14 indicate that the air conditioner 50 is in operation. Arcs 14A and 14B are not displayed when the air conditioner 50 is stopped. When the air conditioner 50 is operating, the current room temperature 14C is displayed at the center of the arcs 14A and 14B. In FIG. 3, "25°C" is displayed as an example of the current room temperature of 14C.
In addition, an up arrow 14D and a down arrow 14E are displayed in the arcs 14A and 14B, and by touching the up arrow 14D and down arrow 14E, the set temperature will be temporarily changed to the current room temperature of 14C. is displayed (not shown), and the set temperature can be changed. Note that after changing the set temperature, the current room temperature of 14C is displayed again.

(circuit board)
The circuit board 15 is mounted with electronic components for controlling the operation of the air conditioner in the controller 1, the display of the operation status, and the like.
As shown in FIG. 4, the circuit board 15 includes a light source 151 (details will be described later) that irradiates light onto the screen panel 20, as an example of an electronic component.
The light source 151 is, for example, a light emitting diode (LED). The light source 151 is provided so as to face an inner end surface 20C, which is located on the space 19 side surrounded by the front section 11, the back section 12, and the side section 13, among the end surfaces connecting the front surface 20A and the back surface 20B of the screen panel 20. The light from the light source 151 is guided into the screen panel 20. Thereby, the light source 151 can illuminate the area of the screen panel 20 through which the light from the light source 151 propagates with light of a desired color. The light source 151 preferably emits light in different colors depending on the operating mode of the air conditioner, for example, it emits red light during heating operation, blue light during cooling operation, green light during dehumidification operation, and white light when operation is stopped. It can be made to emit light or not emit light. This increases the visibility of the operating status of the air conditioner 50 even when the user 102 is away from the controller 1, and can visually determine whether the air conditioner 50 is operating or stopped. The operating mode of the air conditioner 50 can be confirmed.

The light source 151 is preferably arranged at a position where the light from the light source 151 enters the inside of the screen panel 20 from the inner end surface 20C of the screen panel 20. Thereby, reflection of the light from the light source 151 on the inner end surface 20C of the screen panel 20 can be suppressed, and the efficiency of using the light from the light source 151 can be improved.

The light source 151 is preferably arranged at a position where the distance D1 between the light source 151 and the inner end surface 20C of the screen panel 20 shown in FIG. 4 is 2 mm or less. Thereby, it is possible to suppress the amount of light from the light source 151 from decreasing before it is guided into the screen panel 20.
Further, the light source 151 is preferably arranged at a position where the distance D2 between the light source 151 and the outer peripheral surface (an example of the outer edge) 20D of the screen panel 20 shown in FIG. 4 is 15 mm or more and 25 mm or less. When the distance between the light source 151 and the outer peripheral surface 20D of the screen panel 20 is short, when the light that enters the screen panel 20 from the light source 151 propagates inside the screen panel 20 and reaches the outer peripheral surface 20D, the width of the light spreads is It may not be enough. However, when the distance D2 to the outer circumferential surface 20D is 15 mm or more, the light from the light source 151 can be spread with a sufficient width. Further, when the distance D2 to the outer peripheral surface 20D of the screen panel 20 is 25 mm or less, it is possible to prevent the light entering the screen panel 20 from attenuating and not sufficiently propagating to the outer peripheral surface 20D of the screen panel 20.

<Screen panel>
As shown in FIGS. 3B and 4, the screen panel 20 is fixed to the side surface 13 of the main body 10 and stands upright from the side surface 13. The screen panel 20 is made of a material that transmits the light emitted from the light source 151. More specifically, the screen panel 20 is preferably made of a colorless and highly transparent material, and more preferably made of a transparent resin such as glass or acrylic. This suppresses the color of the light emitted from the light source 151 from changing when it passes through the screen panel 20, and allows the user 102 to correctly recognize the driving state from the color of the screen panel 20. Further, the screen panel 20 allows light reflected from the mounting surface 101 of the controller 1 to pass therethrough. The user 102 can visually recognize the color and pattern of the mounting surface 101 (the color and pattern of the wallpaper) through the screen panel 20. Therefore, the controller 1 blends into the mounting surface 101 and harmonizes with the wall surface or the like that serves as the mounting surface 101 of the controller 1.

The thickness of the screen panel 20 is preferably 3 mm or more. Here, the "thickness of the screen panel 20" means from the bottom of the first grain on the front surface 20A where the first grain is formed to the back surface 20B where the second grain is formed as shown in FIG. This refers to the distance T to the bottom of the second grain. That is, the actual thickness of the screen panel 20 becomes thicker than the defined thickness T of the screen panel 20 by the sum of the maximum height H1 of the first grain and the maximum height H2 of the second grain.
Thereby, the light from the light source 151 is sufficiently irradiated onto the inner end surface 20C of the screen panel 20, which is the light incident surface, and is sufficiently incident on the inside of the screen panel 20. Therefore, the appearance of the controller 1 having the screen panel 20 through which light from the light source 151 sufficiently propagates is improved.

FIG. 7A is a perspective view showing an example of the configuration of the screen panel 20. As shown in FIG. 7A, the screen panel 20 has, for example, an upright portion 27 represented by a frame surrounding an opening 25 formed in the center, and has a desired external shape. Here, FIG. 7A shows a configuration example in which the screen panel 20 has a rectangular shape.

The upright portion 27 of the screen panel 20 has an upper side 21 , a right side 22 , a lower side 23 , and a left side 24 . As a result, an opening 25 is formed in the center of the screen panel 20. As shown in FIG. 3A, the screen panel 20 has an outer shape larger than the main body 10 when viewed from the front. In particular, the lower side portion 23 is formed to extend significantly downward from the main body portion 10. Thereby, the screen panel 20 protrudes from the main body 10 to such an extent that the lower side 23 of the screen panel 20 is visible when viewed from the front.
Further, the screen panel 20 has a front surface 20A on which a first grain is formed, a back surface 20B on which a second grain is formed, an inner end surface 20C, and an outer peripheral surface 20D. The inner end surface 20C is a surface located on the space 19 (see FIG. 4) side surrounded by the front section 11, the back section 12, and the side section 13 among the end surfaces connecting the front surface 20A and the back surface 20B. The back surface 20B is a surface located on the side opposite to the space 19 side among the end surfaces connecting the front surface 20A and the back surface 20B. In FIG. 7A, the inner end surface 20C is the inner peripheral surface of the screen panel 20, which is a frame.

Further, as shown in FIG. 4, a light source 151 is arranged above the lower side portion 23. As a result, as shown in FIG. 7A, light from the light source 151 enters the lower side portion 23, and a light emitting display region 23A is generated, which is a region where the light propagates to the lower side portion 23. The visibility of the operating state of the air conditioner 50 is increased by the generation of the light emitting display area 23A.

It is preferable that the screen panel 20 has an upright portion 27 shown as a frame in FIG. 7A, and a light guide portion 26 that protrudes from a part of the upright portion 27 toward the opening 25. FIG. 7A shows a configuration example in which a light guide portion 26 extending to a position close to the lower end of the light source 151 is provided at the center of the lower side portion 23 of the screen panel 20. By providing the light guide section 26, the area through which the light from the light source 151 propagates is limited to the angle of the side surface 26A of the light guide section 26. Therefore, by adjusting the light guide portion 26 to a desired shape, the shape of the light emitting display area 23A through which the light from the light source 151 propagates is adjusted. Further, by providing the light guide section 26, even if the distance between the light emitting display area 23A and the light source 151 is large, it is possible to suppress a decrease in the amount of light propagating to the light emitting display area 23A. Thereby, visibility of the driving state can be further improved.

FIG. 7B shows an enlarged view of the lower side portion 23, the light guide portion 26, and the light source 151. As shown in FIG. 7B, the light guide portion 26 preferably has a trapezoidal shape in which the length L1 of the side facing the light source 151 is shorter than the length L2 of the side on the lower side portion 23 side. At this time, the length L1 of the side facing the light source 151 is preferably at least the width W1 of the light source 151, and is preferably at most 2 mm longer than the width W1 of the light source 151. That is, it is preferable that a clearance of, for example, 1 mm is provided on the left and right sides of the light source 151 with respect to the sides of the light guide section 26 facing the light source 151. When the length of the side facing the light source 151 is greater than or equal to the width Wl of the light source 151, loss of light propagating from the light source 151 into the screen panel 20 can be suppressed. Further, when the length of the side facing the light source 151 is 2 mm longer than the width W1 of the light source 151 or less, the light from the light source 151 propagates over the entire surface of the light guide section 26, improving the aesthetic appearance.

At this time, the light source 151 is arranged within the light source facing surface 26B (see FIG. 7A) of the light guide section 26 that faces the light source 151 when viewed from the light source 151 in the direction of the light guide section 26, that is, when viewed from above. It is preferable. That is, as shown in FIG. 7C, it is preferable that the light source 151 completely overlap the light source facing surface 26B when viewed from above, and it is more preferable that the center of the light source 151 and the center of the light source facing surface 26B coincide. Thereby, loss of light entering the screen panel 20 from the light source 151 via the light source facing surface 26B can be suppressed.

Further, the angle of the side surface 26A of the light guide portion 26 is such that the width Wv at the lower end 23B of the lower side portion 23 between the virtual extension lines Lv of the side surface 26A shown by the dashed line in FIG. 7B is the width of the desired light emitting display area 23A. It is preferable to design it as follows. Thereby, the design of the controller can be improved.

It is preferable that a side surface 26A of the light guide section 26 and a light source facing surface 26B facing the light source 151 shown in FIG. 7B are smooth surfaces. More specifically, the 60 degree specular gloss of the side surface 26A and the light source facing surface 26B is preferably 95 or more, more preferably 98 or more. Here, the 60 degree specular gloss is a value measured by a gloss meter (manufactured by TASCO GLOSS CHECKER, TMS-723 (model number)). The same applies to the glossiness described below.
Thereby, the light from the light source 151 is less likely to be reflected by the light source facing surface 26B, and the light utilization efficiency is further improved. Furthermore, since the light incident on the light guide section 26 enters the smooth side surface 26A within the screen panel 20 at an incident angle, the light is directed downward within the light guide section 26 (toward the lower end 23B of the lower side section 23). This makes it easier to reflect light, further improving the efficiency of light usage.

The screen panel 20 has a first grain formed on the front surface 20A (see FIGS. 4 and 7A) and a second grain formed on the back surface 20B (see FIG. 4). The second grain is formed more coarsely than the first grain. That is, a first grain that is finer than the second grain is formed on the front surface 20A of the screen panel 20, and a second grain that is coarser than the first grain is formed on the back surface 20B of the screen panel 20. has been done.

Since the front surface 20A has the first grain that is finer than the second grain, the screen panel 20 can diffusely reflect the light propagated inside the screen panel 20 from the light source 151 on the front surface 20A. Thereby, the screen panel 20 can illuminate the front surface 20A of the controller 1 with light that gives a soft impression.
Further, as shown in FIG. 8, since the back surface 20B has a second grain that is coarser than the first grain, the screen panel 20 allows the light propagated inside the screen panel 20 from the light source 151 to be directed to the front surface of the back surface 20B. It becomes easier to reflect in the 20A direction. Thereby, the screen panel 20 can increase the amount of light guided toward the front surface 20A of the screen panel 20.

The glossiness of the front surface 20A where the first grain is provided can be set to a desired glossiness depending on the softness of the light to be produced, and the glossiness of the back surface 20B where the second grain is provided can be set to the desired glossiness of the controller 1. The gloss level is such that the color and pattern of the mounting surface 101 are appropriately visible and the light incident on the screen panel 20 is reflected toward the front surface 20A. The difference between the 60 degree specular gloss of the front surface 20A of the screen panel 20 and the 60 degree specular gloss of the back surface 20B is preferably 0.5 or more and 8.5 or less. Further, the 60 degree specular gloss of the front surface 20A is preferably 3 or more and 10 or less, more preferably 3 or more and 5 or less. Further, the 60 degree specular gloss of the back surface 20B is preferably 1.5 or more and 3 or less.

Furthermore, the screen panel 20 has a third grain rougher than the first grain and the second grain on the inner end surface 20C (see FIG. 7A) excluding the incident area where the light from the light source 151 enters. It is preferable to have. In addition, when the screen panel 20 has the light guide part 26, the screen panel 20 has a third part on the inner end face 20C, excluding the area where the light guide part 26 is formed, of the inner face facing the opening part 25. It is preferable to have a grain of . By providing the third grain on the inner end surface 20C of the screen panel 20, the inner end surface 20C becomes cloudy and the inside of the main body 10 cannot be seen from the outside of the controller 1.

The screen panel 20 is clamped and fixed by two or more parts that constitute the main body 10. At this time, the circuit board 15 and the like inside the main body section 10 may become visible to the outside of the controller 1 through the screen panel 20 formed of a highly transparent material. By providing the third grain and using the screen panel 20 whose inner end surface 20C is cloudy, the interior of the main body portion 10 cannot be seen from the outside of the controller 1, thereby improving the aesthetic appearance of the controller 1. .
The glossiness of the inner end surface 20C provided with the third grain is preferably 1 or less, for example, in order to make the inside of the main body part 10 invisible.

Here, the difference in grain roughness can be defined from the following two viewpoints.
In the first example, the roughness of the grains is made to differ depending on the height of the grains. For example, the second grain is formed higher than the first grain, so that the second grain is formed coarser than the first grain. Here, the "height" of the grain is the value of the ten-point average roughness Rz measured according to JIS B0601. The same applies to "height" which will be explained later.
In this case, the height of the second grain is preferably 2 μm or more higher than the height of the first grain, and the height of the first grain is 13 μm or more and 16 μm or less and the height of the second grain is higher than the height of the first grain. is more preferably 15 μm or more and 18 μm or less. Further, the height of the third grain is preferably 31 μm or more and 36 μm or less.

In the second example, the roughness of the grains is made to differ depending on the shape of the grains. For example, it is preferable that the first grain be formed with smooth irregularities, and the second grain be formed with angular irregularities. Since the second grain is formed with irregularities that are more angular than the first grain, the second grain is formed more coarsely than the first grain.
Here, FIG. 6A is a cross-sectional view of a grain formed with smooth irregularities, and FIG. 6B is a cross-sectional view of a grain formed with angular irregularities. As shown in FIGS. 6A and 6B, "angular unevenness" means that the kurtosis of the contour curved surface of the grain is higher than "smooth unevenness", and "smooth unevenness" means "angular unevenness". '' means that the kurtosis of the grain contour surface is lower than that of . The "smooth unevenness" means that at least the ridgeline surface at the tip of the grain is smooth, and the ridgeline surface at the bottom of the grain may have a smooth shape or a linear shape. The front surface 20A on which the first grains, which are smooth irregularities, are formed diffusely reflects the light propagated within the screen panel 20 in various directions. Therefore, the screen panel 20 can be illuminated with light that gives a soft impression. On the other hand, the back surface 20B on which the second grain, which is linear unevenness, is formed tends to reflect the light propagated within the screen panel 20 linearly toward the front surface 20A.

In this case, the heights of the first grain and the second grain may be the same, and are preferably 13 μm or more and 18 μm or less. Since the first grain on the front surface 20A has a smooth surface shape and the second grain on the back surface 20B has an angular surface shape, the heights of the first grain and the second grain are the same. The grains also have different roughness. Therefore, the screen panel 20 can illuminate the front surface 20A with soft light through the first grain. In addition, in the screen panel 20, the light propagated from the light source 151 inside the screen panel 20 is easily reflected to the front surface 20A at the back surface 20B due to the second grain, increasing the amount of light traveling toward the front surface 20A of the screen panel 20. can be done. Also in this case, the height of the third grain is preferably 31 μm or more and 36 μm or less.

Furthermore, the screen panel 20 may have an inclined surface inclined with respect to the front surface 20A, at least in the light emitting display area 23A through which light from the light source 151 propagates. The inclined surface is inclined such that the thickness of the upright portion 27 becomes thinner as the distance from the light source 151 increases. The inclined surface is a surface that adjusts the direction of light so that it can be seen by the user 102, and the degree of inclination of the inclined surface can be adjusted as appropriate. The inclined surface may be provided on at least one of the outer edge of the upright portion 27 of the screen panel 20 on the side far from the light source 151 (the outer circumferential surface 20D shown in FIG. 7A) and the area between the opening 25 and the outer circumferential surface 20D. Bye.

For example, FIG. 9A shows a configuration example in which an inclined surface 23C is provided between the front surface 20A and the outer peripheral surface 20D of the screen panel 20 (lower end 23B of the lower side portion 23 shown in FIG. 7A). Further, FIG. 9A shows the light displayed on the light emitting display area 23A and the inclined surface 23C of the lower side part 23, and the darker the shading in the figure, the stronger the light is displayed. FIG. 9A shows the light guide section 26 and the lower side section 23 that is a part of the upright section 27. The inclined surface 23C is formed to be inclined with respect to the front surface 20A of the lower side portion 23 by cutting out a corner portion of the lower end of the lower side portion 23 on the front surface 20A side. As a result, light is guided to the front surface of the controller 1 as shown in FIG. 9B, so that strong light is displayed on the inclined surface 23C due to the prism effect. Thereby, the controller 1 can create a contrast between the soft light from the front surface 20A of the screen panel 20 and the strong light from the inclined surface 23C, and can obtain a high aesthetic appearance.

Note that in FIG. 9A, the inclined surface 23C is formed at the lower end 23B of the lower side portion 23, but the present invention is not limited to such a configuration.
