The present disclosure will be described below through embodiments, but the following embodiments do not limit the scope of the invention according to the claims. In addition, not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention.
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 with reference to Fig. 1 to Fig. 8B. In this embodiment, a controller that is fixed to a mounting surface such as a wall surface of a house and controls an indoor unit of the air conditioner will be described.

As shown in FIG. 1, the controller 1 of the air conditioner according to the present disclosure is connected to the air conditioner 50 by wire or wirelessly, and has the function of transmitting an operation control signal to the air conditioner 50 and displaying the operation status of the air conditioner 50. The air conditioner 50 may be, for example, a ceiling-embedded air conditioner as shown in FIG. 1, or a duct-type air conditioner (not shown in FIG. 1), and the type of the air conditioner is not limited. The controller 1 is attached to a mounting surface 101, such as a wall surface inside a room, by 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. 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 light onto the screen panel 20. Here, FIG. 2 shows an example of a configuration in which the main body 10 has a hollow rectangular parallelepiped shape. The light source 151 emits light in different colors according to the operation mode of the air conditioner 50 to illuminate the screen panel 20. This allows the user 102 to visually check whether the air conditioner 50 is operating or not, and which operation mode the air conditioner 50 is in, even if the user 102 is in a place far from the controller 1. This improves the visibility of the operation state of the air conditioner 50.
Each component of the air conditioner controller 1 will be described in detail below.

<Main body>
2, the main body 10 has a rectangular front portion 11 on which the display 14 is disposed, a rear portion 12 provided on the rear side of the display 14, and a side portion 13 connecting the front portion 11 and the rear portion 12. The rear portion 12 is provided with an attachment portion (not shown) that enables attachment to an attachment surface 101. Inside the main body 10, a circuit board 15 (described in detail later) and the like are disposed.

Fig. 3A is a front view of the controller 1, showing an example of the display unit 14. For the sake of explanation, Fig. 3 shows the display unit 14 shown in Fig. 2 in black and white inversion. Fig. 3B is a right side view of the controller 1. Fig. 4 is a cross-sectional view showing the A-A cross section of the controller 1 shown in Fig. 3. 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 sandwiched and fixed by the plurality of parts, for example, a case 16 which serves as a front case and a base 17 which serves as a rear case.

(Display)
The display unit 14 is exposed on the front surface 11 side, for example, and is surrounded by a case 16, which is the exterior of the main body 10, when viewed from the front. The display unit 14 is a display screen having a liquid crystal screen that has a function of a touch panel operation unit for operating the air conditioner 50 and a function of a display unit for displaying the operating status of the air conditioner 50.
The display unit 14 is formed, for example, by overlaying 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 level of design.

As shown in Fig. 3A, the operating status of the air conditioner 50 is displayed on the display unit 14. Large arcs 14A and 14B in the centre of the display unit 14 indicate that the air conditioner 50 is operating. The arcs 14A and 14B are not displayed when the air conditioner 50 is not operating. When the air conditioner 50 is operating, the current room temperature 14C is displayed in the centre of the arcs 14A and 14B. In Fig. 3, "25°C" is displayed as an example of the current room temperature 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 the down arrow 14E, the set temperature is temporarily displayed (not shown) instead of the current room temperature 14C, and the set temperature can be changed. After the set temperature is changed, the current room temperature 14C is displayed again.

(Circuit board)
The circuit board 15 has electronic components mounted thereon for controlling the operation of the air conditioner in the controller 1 and displaying the operating status.
As shown in FIG. 4, the circuit board 15 includes a light source 151 (described in detail below) 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 to face an inner end surface 20C located on the side of the space 19 surrounded by the front part 11, the rear part 12, and the side part 13 among the end surfaces connecting the front surface 20A and the rear surface 20B of the screen panel 20, and light from the light source 151 is guided into the screen panel 20. As a result, the light source 151 can illuminate the area of the screen panel 20 to which the light from the light source 151 propagates with light of a desired color. The light source 151 preferably emits light of different colors depending on the operation mode of the air conditioner, and can emit light of red during heating operation, blue during cooling operation, green during dehumidification operation, and white or no light when the operation is stopped. As a result, the visibility of the operation state of the air conditioner 50 is improved even when the user 102 is in a place away from the controller 1, and the user 102 can visually check whether the air conditioner 50 is operating or stopped and the operation mode of the air conditioner 50.

The light source 151 is preferably disposed 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. This makes it possible to suppress reflection of the light from the light source 151 at the inner end surface 20C of the screen panel 20, thereby improving the efficiency of light utilization of the light from the light source 151.

The light source 151 is preferably disposed at a position where a 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. This makes it possible to suppress a decrease in the amount of light from the light source 151 before it is guided into the screen panel 20.
In addition, the light source 151 is preferably disposed at a position where the distance D2 between the light source 151 and the outer peripheral surface (one 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, the width of the light that spreads may not be sufficient when the light that has entered the screen panel 20 from the light source 151 propagates through the screen panel 20 and reaches the outer peripheral surface 20D. However, when the distance D2 to the outer peripheral surface 20D is 15 mm or more, the light from the light source 151 can be made to spread with a sufficient width. In addition, when the distance D2 to the outer peripheral surface 20D of the screen panel 20 is 25 mm or less, it is possible to suppress the light that has entered the screen panel 20 from being attenuated and not being sufficiently propagated to the outer peripheral surface 20D of the screen panel 20.

<Screen panel>
As shown in FIG. 3B and FIG. 4, the screen panel 20 is fixed to the side surface portion 13 of the main body portion 10 and stands upright from the side surface portion 13. The screen panel 20 is made of a material that transmits the light irradiated 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 being changed by passing through the screen panel 20, and the user 102 can correctly recognize the operating state from the color of the screen panel 20. In addition, the screen panel 20 transmits the light reflected from the mounting surface 101 of the controller 1. The user 102 can visually recognize the color and pattern (color and pattern of the wallpaper) of the mounting surface 101 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" refers to the distance T from the bottom of the first texture on the front surface 20A on which the first texture is formed to the bottom of the second texture on the back surface 20B on which the second texture is formed, as shown in Fig. 5. That is, the actual thickness of the screen panel 20 is thicker than the defined thickness T of the screen panel 20 by the sum of the maximum height H1 of the first texture and the maximum height H2 of the second texture.
As a result, 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 screen panel 20. This improves the aesthetic appearance of the controller 1, which has a screen panel 20 through which the light from the light source 151 propagates sufficiently.

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

The erected portion 27 of the screen panel 20 has an upper side portion 21, a right side portion 22, a lower side portion 23, and a left side portion 24. This forms an opening 25 in the center of the screen panel 20. As shown in Fig. 3A, the screen panel 20 is formed to have an outer shape larger than the main body portion 10 in a front view. In particular, the lower side portion 23 is formed so as to extend significantly downward from the main body portion 10. This causes the screen panel 20 to protrude from the main body portion 10 to an extent that the lower side portion 23 of the screen panel 20 can be seen in a front view.
The screen panel 20 has a front surface 20A on which a first texture is formed, a rear surface 20B on which a second texture is formed, an inner end surface 20C, and an outer peripheral surface 20D. The inner end surface 20C is a surface that is located on the side of a space 19 (see FIG. 4 ) surrounded by the front surface 11, the rear surface 12, and the side surface 13, among the end surfaces connecting the front surface 20A and the rear surface 20B. The rear surface 20B is a surface that is located on the side opposite to the space 19, among the end surfaces connecting the front surface 20A and the rear surface 20B. In FIG. 7A , the inner end surface 20C is an inner peripheral surface of the screen panel 20, which is a frame body.

As shown in FIG. 4, a light source 151 is disposed above the bottom side 23. As a result, as shown in FIG. 7A, light from the light source 151 is incident on the bottom side 23, and a light-emitting display area 23A is generated, which is an area where the light propagates to the bottom side 23. The generation of the light-emitting display area 23A improves the visibility of the operating state of the air conditioner 50.

The screen panel 20 preferably has an erected portion 27 shown by a frame in FIG. 7A and a light guide portion 26 protruding from a part of the erected portion 27 toward the opening 25. FIG. 7A shows an example of a configuration in which the light guide portion 26 is provided in the center of the lower side portion 23 of the screen panel 20, extending to a position close to the lower end of the light source 151. By providing the light guide portion 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 portion 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. In addition, by providing the light guide portion 26, it is possible to suppress a decrease in the amount of light propagating to the light-emitting display area 23A even if the distance between the light-emitting display area 23A and the light source 151 is large. This makes it possible to further improve the visibility of the driving state.

7B shows an enlarged view of the lower side 23, the light guide 26, and the light source 151. As shown in FIG. 7B, the light guide 26 is preferably trapezoidal 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 23 side. In this case, the length L1 of the side facing the light source 151 is preferably equal to or greater than the width W1 of the light source 151, and is preferably equal to or less than 2 mm longer than the width Wl 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 side of the light guide 26 facing the light source 151. When the length of the side facing the light source 151 is equal to or greater than the width Wl of the light source 151, the loss of light propagating from the light source 151 into the screen panel 20 can be suppressed. When the length of the side facing the light source 151 is equal to or less than 2 mm longer than the width W1 of the light source 151, the light from the light source 151 propagates over the entire surface of the light guide 26, improving the aesthetic appearance.

In this case, when looking from the light source 151 towards the light guide section 26, that is, when viewed from above, the light source 151 is preferably disposed within the plane of the light-source facing surface 26B (see FIG. 7A) that faces the light source 151 of the light guide section 26. That is, as shown in FIG. 7C, when viewed from above, it is preferable that the light source 151 completely overlaps the light-source facing surface 26B, and it is even more preferable that the center of the light source 151 coincides with the center of the light-source facing surface 26B. This makes it possible to suppress the loss of light entering the screen panel 20 from the light source 151 via the light-source facing surface 26B.

The angle of the side 26A of the light guide 26 is preferably designed so that the width Wv at the lower end 23B of the lower edge 23 between the imaginary extension lines Lv of the side 26A, shown by the dashed line in FIG. 7B, is the desired width of the light-emitting display area 23A. This can improve the design of the controller.

Side surface 26A of light guiding section 26 shown in Fig. 7B and light-source-facing surface 26B facing light source 151 are preferably smooth surfaces. More specifically, the 60-degree specular gloss of side surface 26A and light-source-facing surface 26B is preferably 95 or more, and more preferably 98 or more. Here, the 60-degree specular gloss is a value measured with a glossmeter (TMS-723 (model number) manufactured by TASCO GLOSS CHECKER). The same applies to the gloss levels described hereinafter.
This makes it difficult for light from light source 151 to be reflected by light-source-facing surface 26B, further improving the efficiency of light utilization. In addition, since the light incident on light-guiding section 26 is incident on smooth side surface 26A within screen panel 20 at an incident angle, the light is more likely to be reflected downward within light-guiding section 26 (towards lower end 23B of lower side section 23), further improving the efficiency of light utilization.

The screen panel 20 has a first texture formed on the front surface 20A (see Figures 4 and 7A) and a second texture formed on the back surface 20B (see Figure 4). The second texture is formed coarser than the first texture. That is, the front surface 20A of the screen panel 20 has a first texture that is finer than the second texture, and the back surface 20B of the screen panel 20 has a second texture that is coarser than the first texture.

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 that has propagated from the light source 151 through the inside of the screen panel 20 at the front surface 20A. This allows the screen panel 20 to illuminate the front surface 20A of the controller 1 with light that gives a soft impression.
8, the rear surface 20B has the second texture that is coarser than the first texture, so that the screen panel 20 can easily reflect the light that has propagated from the light source 151 inside the screen panel 20 toward the front surface 20A at the rear surface 20B. This enables the screen panel 20 to increase the amount of light guided toward the front surface 20A of the screen panel 20.

The glossiness of the front surface 20A on which the first texture 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 on which the second texture is provided is a glossiness that can reflect the light incident on the screen panel 20 to the front surface 20A side while allowing the color and pattern of the mounting surface 101 of the controller 1 to be appropriately visible. The difference between the 60-degree specular glossiness of the front surface 20A of the screen panel 20 and the 60-degree specular glossiness of the back surface 20B is preferably 0.5 to 8.5. The 60-degree specular glossiness of the front surface 20A is preferably 3 to 10, more preferably 3 to 5. Furthermore, the 60-degree specular glossiness of the back surface 20B is preferably 1.5 to 3.

Furthermore, the screen panel 20 preferably has a third texture formed coarser than the first texture and the second texture on the inner end surface 20C (see FIG. 7A) excluding the incident area where the light from the light source 151 is incident. Furthermore, when the screen panel 20 has a light guide section 26, the screen panel 20 preferably has a third texture on the inner end surface 20C of the inner side surface facing the opening 25 excluding the area where the light guide section 26 is formed. By providing the third texture on the inner end surface 20C of the screen panel 20, the inner end surface 20C becomes cloudy, making it impossible to see the inside of the main body section 10 from outside the controller 1.

The screen panel 20 is sandwiched and fixed between two or more components that constitute the main body 10. At this time, the circuit board 15 and the like inside the main body 10 may be visible from the outside of the controller 1 through the screen panel 20, which is made of a highly transparent material. By using a screen panel 20 in which the inner end surface 20C is clouded by providing the third grain, the inside of the main body 10 cannot be seen from the outside of the controller 1, improving the aesthetic appearance of the controller 1.
The glossiness of the inner end surface 20C on which the third grain is provided is preferably, for example, 1 or less, so as to make the inside of the main body 10 invisible.

Here, the difference in the roughness of the grain can be defined from the following two viewpoints.
In the first example, the roughness of the grain is made different by changing the grain height. 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 in accordance with JIS B0601. The same applies to the "height" described below.
In this case, the height of the second grain is preferably 2 μm or more higher than the height of the first grain, more preferably the height of the first grain is 13 μm or more and 16 μm or less and the height of the second grain is 15 μm or more and 18 μm or less, and the height of the third grain is preferably 31 μm or more and 36 μm or less.

In a second example, the roughness of the grain is made different by changing the grain shape. For example, it is preferable that the first grain is formed with smooth irregularities and the second grain is formed with angular irregularities. Since the second grain is formed with angular irregularities more than the first grain, the second grain is formed coarser than the first grain.
Here, FIG. 6A is a cross-sectional view of the grain formed by smooth unevenness, and FIG. 6B is a cross-sectional view of the grain formed by angular unevenness. As shown in FIG. 6A and FIG. 6B, "angular unevenness" means that the contour curved surface of the grain has a higher kurtosis than "smooth unevenness", and "smooth unevenness" means that the contour curved surface of the grain has a lower kurtosis than "angular unevenness". "Smooth unevenness" means that at least the ridge surface at the tip of the grain is smooth, and the ridge surface at the bottom of the grain may have a smooth shape or a linear shape. The front surface 20A on which the first grain, which is a smooth unevenness, is formed diffuses light propagated in 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 a linear unevenness, is formed makes it easier to linearly reflect light propagated in the screen panel 20 toward the front surface 20A.

In this case, the height of the first and second embossments may be the same, and is preferably 13 μm to 18 μm. Since the first embossment on the front surface 20A has a smooth surface shape and the second embossment on the back surface 20B has an angular surface shape, the first and second embossments have different roughness even if they are the same height. Therefore, the screen panel 20 can make the front surface 20A shine with light that gives a soft impression through the first embossment. In addition, the second embossment of the screen panel 20 makes it easier for the light propagated from the light source 151 inside the screen panel 20 to be reflected by the back surface 20B to the front surface 20A, thereby increasing the amount of light traveling in the direction of the front surface 20A of the screen panel 20. In this case, the height of the third embossment is preferably 31 μm to 36 μm.

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 so that the thickness of the standing portion 27 becomes thinner the farther from the light source 151. The inclined surface is a surface that adjusts the direction of light so that it is visible to 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 (outer peripheral surface 20D shown in FIG. 7A) on the side of the standing portion 27 of the screen panel 20 that is farther from the light source 151 and the area between the opening 25 and the outer peripheral surface 20D.

9A shows an example of a configuration in which an inclined surface 23C is provided between the front surface 20A and the outer peripheral surface 20D of the screen panel 20 (the lower end 23B of the lower side portion 23 shown in FIG. 7A). FIG. 9A also shows the light-emitting display area 23A of the lower side portion 23 and the light displayed on the inclined surface 23C, with the darker shading in the figure indicating the stronger light being displayed. FIG. 9A shows the light-guiding section 26 and the lower side portion 23, which is a part of the erected portion 27. The inclined surface 23C is formed at an incline with respect to the front surface 20A of the lower side portion 23 by cutting out the corner of the lower end of the front surface 20A side of the lower side portion 23. As a result, light is guided to the front surface of the controller 1 as shown in FIG. 9B, and strong light is displayed on the inclined surface 23C due to the prism effect. As a result, the controller 1 creates 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.

In FIG. 9A, the inclined surface 23C is formed at the lower end 23B of the lower side portion 23, but this is not limited to the configuration. The inclined surface 23C may be formed in the light-emitting display area 23A other than the lower end 23B of the lower side portion 23. For example, as shown in FIG. 10A and FIG. 10B, the inclined surface 23C may be formed as part of a groove portion 23D (the surface of the groove portion 23D on the light source 151 side) provided on the front surface 20A of the lower side portion 23, which is part of the erected portion 27. Here, the groove portion 23D may be a recess as shown in FIG. 10A and FIG. 10B, or may be a hole (not shown).

In addition, in this embodiment, the screen panel 20, which is a frame body, is illustrated and described, but is not limited to such a configuration. For example, the screen panel 20 may be formed of only the lower side portion 23 and the light guide portion 26, as shown in Figures 9A and 10A.

Although the embodiments of the present disclosure have been described above, the above embodiments are merely examples of devices and methods for embodying the technical ideas of the present disclosure, and the technical ideas of the present disclosure do not specify the materials, shapes, structures, arrangements, etc. of the components.
