Below, an embodiment in which the remote control device of the present invention is applied to a controller for an air conditioner will be described. Figures 1 to 6 show six-sided views of the remote control device 1 according to this embodiment, Figure 7 shows an example display of the remote control device 1, and Figure 8 shows a cross-sectional view of the remote control device 1 taken along line A-A.

The remote control device 1 according to this embodiment is configured with a case 10, a base unit 20, an operation unit 30, and a display unit 40.

The case 10 has an upper case 11 and a lower case 12.

The upper case 11 is formed in a cylindrical shape from transparent resin or glass, and is configured so that the display unit 40 can be seen through the upper case 11. The upper case 11 is configured so that it can be connected to the top of the base unit 20.

The lower case 12 is formed into a cylindrical shape using transparent resin or glass, and is configured so that it can be connected to the lower part of the base 20. The lower case 12 may also be formed with legs for allowing the remote control device 1 to stand.

The base 20 has a first lighting section 21, a second lighting section 22, a body section 23, a lower case cover 24, a hole 28, and a power supply section 29, and stores a control board 25 inside the base 20.

The first lighting section 21 is semi-cylindrical and is provided on the upper front side of the body section 23, and is configured to cover the status LED 21A with a light guide plate 21B. The first lighting section 21 has a diffusion plate 21C on the upper surface of the light guide plate 21B.

The second illumination section 22 is semi-cylindrical and is provided on the upper rear side of the body section 23, and is configured to cover the status LED 22A with a light guide plate 22B. The second illumination section 22 has a diffusion plate 22C on the upper surface of the light guide plate 22B.

The status LED 21A and the status LED 22A are color LEDs, and are light sources that light up at a specified color and brightness under the control of the control unit 25A, which will be described later.

Light guide plate 21B and light guide plate 22B are light guide members made of transparent resin and are disposed at the bottom of display unit 40, and are configured to glow in the illumination color when illuminated by status LED 21A and status LED 22A and be visible.

The diffusion plates 21C and 22C diffuse the illumination light guided by the light guide plates 21B and 22B in the direction of the display unit 40. This allows the remote control device 1 to present an effect in which the display on the display unit 40 appears to emerge from the diffused illumination light, improving the interior design of the remote control device 1.

The body 23 is formed into a cylindrical shape using resin or metal, and is configured to be connectable to the upper case 11 and the lower case 12.

The lower case cover 24 is provided on the lower part of the body 23 and covers the opening at the lower part of the body 23. The lower case cover 24 is configured so that a hole is provided in at least a part of the lower case cover 24 and the status LED 24A protrudes from the hole. The lower case cover 24 may have a hole provided in accordance with the size of the board on which the status LED 24A is mounted.

The status LED 24A is a light source that lights up in a specified color and brightness under the control of the control unit 25A, which will be described later, and illuminates the lower case 12.

The control board 25 has a control unit 25A, a memory unit 25B, and a transmission unit 25C, and is electrically connected to the status LED 21A, the status LED 22A, the status LED 24A, the operation unit 30, and the display unit 40. The control board 25 may also be equipped with a temperature and humidity sensor (not shown) to measure the indoor environment.

The control unit 25A is composed of a circuit, which includes at least one processor (e.g., a central processing unit (CPU)), at least one application specific integrated circuit (ASIC), and/or at least one semiconductor integrated circuit such as a field programmable gate array (FPGA), and is capable of executing all or part of the functions of the remote control device 1.
The control unit 25A can adjust the luminance of the status LED 21A, the status LED 22A, the status LED 24A, and a backlight LED 43 (described later) by adjusting the duty ratio through pulse width modulation (PWM) of the applied voltage.

The storage unit 25B is configured with a non-volatile memory such as a magnetic recording medium or a flash memory, and is capable of storing the control software of the remote control device 1, the display image of the display unit 40, and the like. The storage unit 25B may be configured integrally with the control unit 25A.

The transmitting unit 25C is composed of an infrared LED that emits infrared rays to the air conditioner as a remote control signal. The infrared rays emitted from the transmitting unit 25C are guided to the upper surface of the second lighting unit 22 by the light guide plate 22B and diffused by the diffusion plate 22C, making it possible to transmit a remote control signal to an air conditioner that is not in a straight line with the transmitting unit 25C. The remote control device 1 may further include a receiving unit composed of an infrared sensor that receives infrared rays as a response signal from the air conditioner.

Hole 28 is a hole provided on the back of the body 23, exposing the power supply unit 29 to the outside.

The power supply unit 29 is a connector configured to allow a power cable or a USB cable to be connected, and supplies power to the remote control device 1 .
The remote control device 1 may be supplied with power from a battery instead of a wired power supply.

The operation unit 30 is a semicircular lid made of resin, metal, or the like, and is disposed on the top of the upper case 11 .
The operation unit 30 has a plurality of operation buttons, including, for example, a mode button 30A for changing the operation mode of the air conditioner, a display button 30B for switching the display on the display unit 40, a power button 30C for turning the power on and off to the remote control device 1, a down button 30D for lowering the set temperature of the air conditioner, and an up button 30E for raising the set temperature of the air conditioner. Icons indicating the correspondence between the operation buttons and their functions may be printed on the operation unit 30.
The operation unit 30 also has a holding portion 31 which is a recess on the side opposite to the operation buttons, and the holding portion 31 holds a front cover 44 and a rear cover 45 of the display unit 40 .
The operation unit 30 is connected to the control board 25 by an electric wire 32 , and the electric wire 32 is hidden by a panel 33 .

The electric wires 32 are made of conductive metal and transmit operation information of the operation unit 30 to the control unit 25A. The electric wires 32 are wired from the operation unit 30 to the base unit 20 along the side of the display unit 40, so that the remote control device 1 is not noticeable when a user views the remote control device 1 from the front. The electric wires 32 may be made of conductive ink.

The panels 33 are plate-like members arranged on the left and right inside the upper case 11 to connect the operation unit 30 to the base unit 20. This makes it possible to hide the presence of the electric wires 32 when the user views the remote control device 1 from the side.

A liquid crystal display (LCD) can be used as the display unit 40. The display unit 40 is driven and controlled by a control signal from the control unit 25A, and can display operation information based on the operation of the operation unit 30, the setting state of the air conditioner that is the communication target, room temperature, humidity, time, calendar, and the like.
The display unit 40 includes a liquid crystal panel 41 , a light guide plate 42 , a backlight LED 43 , a front cover 44 , and a rear cover 45 .

The liquid crystal panel 41 displays images and text by switching between a transparent state and a non-transparent state for each area or pixel under the control of the control unit 25A. By using a liquid crystal panel 41 that is transparent in areas where no voltage is applied, such as a TN type, the remote control device 1 can allow the outside view to be seen through the upper case 11 and the display unit 40, improving the interior design of the remote control device 1.

The light guide plate 42 guides the light from the backlight LEDs 43 and diffuses it using a diffusion film (not shown), allowing the display on the liquid crystal panel 41 to be viewed by the user. The light guide plate 42 may also be formed with reflective dots (not shown).

The backlight LEDs 43 are single-color (e.g., white) LEDs that illuminate the light guide plate 42 under the control of the control unit 25A. The backlight LEDs 43 are disposed below the upper surfaces of the light guide plates 21B and 22B and are configured so as not to be visible to the user. Note that the backlight LEDs 43 may be disposed at the corners of the light guide plate 42, rather than at the center of the light guide plate 42.

The front cover 44 and the rear cover 45 are made of transparent resin and protect the liquid crystal panel 41 by sandwiching it between them. The lower parts of the front cover 44 and the rear cover 45 are held by the light guide plates 21B and 22B, and the upper parts are held by the holding part 31, so that the display part 40 stands upright stably.

When the remote control device 1 is powered off, it turns off the display unit 40, the first illumination unit 21, and the second illumination unit 22. When the remote control device 1 is powered on, it displays on the display unit 40 according to the function, and illuminates the first illumination unit 21 and the second illumination unit 22 in a color according to the function.

When the display unit 40 indicates an air conditioning function, the remote control device 1 illuminates the first lighting unit 21 and the second lighting unit 22 in a first color group corresponding to the air conditioning function. The remote control device 1 assigns, for example, blue to the cooling function, red to the heating function, and green to the dehumidification function. The control unit 25A also adjusts the shade of the lighting color according to the set temperature. This allows the remote control device 1 to confirm the function indicated by the display unit 40 from the lighting color of the first lighting unit 21 and the second lighting unit 22, and to indirectly illuminate the display unit 40 to enhance the interior design.

When the display unit 40 indicates the air conditioning function and the set temperature is changed, the remote control device 1 adjusts the illumination color of the first illumination unit 21 and the second illumination unit 22 to be darker when the air conditioning function is strengthened, and to be lighter when the air conditioning function is weakened. That is, when the operation mode is cooling or dehumidification, the remote control device 1 darkens the illumination color of the first illumination unit 21 and the second illumination unit 22 when the set temperature drops, and lightens the illumination color of the first illumination unit 21 and the second illumination unit 22 when the set temperature rises. Also, when the operation mode is heating, the remote control device 1 darkens the illumination color of the first illumination unit 21 and the second illumination unit 22 when the set temperature rises, and lightens the illumination color of the first illumination unit 21 and the second illumination unit 22 when the set temperature drops.
The remote control device 1 may treat colors corresponding to air conditioning functions and similar colors that change depending on the set temperature as a first color group.

When the display unit 40 is displaying a function other than the air conditioning function, the remote control device 1 illuminates the first illumination unit 21 and the second illumination unit 22 with a second color group different from the first color group used for the air conditioning function. The remote control device 1 assigns yellow to, for example, a calendar display, a clock display, and an indoor environment display. At this time, the remote control device 1 assigns the operation of the down button 30D and the up button 30E to another operation, for example, switching the month display of the calendar. This allows the remote control device 1 to inform the user that the change in the set temperature by the operation button is invalid by the illumination color of the first illumination unit 21 and the second illumination unit 22. The remote control device 1 may change the intensity of the illumination color of the first illumination unit 21 and the second illumination unit 22 according to the indoor environment such as temperature and humidity.
In addition, the remote control device 1 may be equipped with a lantern effect that illuminates the first lighting unit 21 and the second lighting unit 22 with incandescent light or warm white light, or an illumination effect that sequentially changes the lighting colors of the first lighting unit 21 and the second lighting unit 22.

The remote control device 1 may control the status LED 24A in the same manner as the status LEDs 21A and 22A of the first and second illumination units 21 and 22. This allows the remote control device 1 to illuminate both the upper and lower sides of the base unit 20 in a color corresponding to the display on the display unit 40, enhancing the interior design.

Please refer to Figure 9. Figure 9 is a flowchart showing the control of the backlight LED 43 of the remote control device 1.

In step SP1, the control unit 25A controls the brightness of the backlight LED 43 to normal brightness L1.

In step SP2, the control unit 25A determines whether the operation unit 30 has been operated. If it is determined that the operation unit 30 has been operated (Yes), the process proceeds to step SP3. If it is determined that the operation unit 30 has not been operated (No), the process proceeds to step SP5.

In step SP3, the control unit 25A controls the brightness of the backlight LED 43 to an emphasis brightness L2 that is stronger than the normal brightness L1 in order to make the display on the display unit 40 easier to see.

In step SP4, the control unit 25A sets the first timer T1 to a predetermined value.

In step SP5, the control unit 25A determines whether the first timer T1 is counting. If it is determined that the first timer T1 is counting (Yes), the control unit 25A proceeds to step SP6. If it is determined that the first timer T1 is not counting (No), the control unit 25A proceeds to step SP11.

In step SP6, the control unit 25A counts (decrements) the first timer T1.

In step SP7, the control unit 25A determines whether the counting of the first timer T1 has been completed. If it is determined that the counting has been completed (Yes), the control unit 25A proceeds to step SP8, and if it is determined that the counting has not been completed (No), the control unit 25A proceeds to step SP2.

In step SP8, the control unit 25A sets the second timer T2 to a predetermined value and proceeds to step SP2.

In step SP11, the control unit 25A determines whether the second timer T2 is counting. If it is determined that the second timer T2 is counting (Yes), the process proceeds to step SP12. If it is determined that the second timer T2 is not counting (No), the process proceeds to step SP2.

In step SP12, the control unit 25A counts (decrements) the second timer T2.

In step SP13, the control unit 25A controls the backlight LED 43 to gradually dim from the highlight brightness L2 toward the normal brightness L1.

In step SP14, the control unit 25A determines whether the counting of the second timer T2 is complete. If it is determined that the counting is complete (Yes), the control process for the backlight LED 43 ends, and if it is determined that the counting is not complete (No), the control unit 25A proceeds to step SP2.

Please refer to Figure 10. Figure 10 is a flowchart showing the control of the status LEDs 21A, 22A, and 24A of the remote control device 1.

In step SP31, the control unit 25A lights up the status LEDs 21A, 22A, and 24A in a color corresponding to the function displayed on the display unit 40.

In step SP32, the control unit 25A determines whether the operation unit 30 has been operated. If it is determined that the operation unit 30 has been operated (Yes), the process proceeds to step SP33, and if it is determined that the operation unit 30 has not been operated (No), the control ends without changing the illumination color and brightness of the status LEDs 21A, 22A, and 24A.

In step SP33, the control unit 25A determines which operation button has been operated. If it determines that the mode button 30A has been operated, the process proceeds to step SP34. If it determines that the display button 30B has been operated, the process proceeds to step SP41. If it determines that the down button 30D or the up button 30E has been operated, the process proceeds to step SP51.
When it is determined that the power button 30C has been operated, a known power ON/OFF process can be used, and therefore a description thereof will be omitted.

In step SP34, the control unit 25A lights up the status LEDs 21A, 22A, and 24A in a color corresponding to the air conditioning function displayed on the display unit 40.

In step SP35, the control unit 25A adjusts the brightness of the status LEDs 21A, 22A, and 24A to a value that corresponds to the set temperature of the air conditioning function displayed on the display unit 40.

In step SP41, the control unit 25A lights up the status LEDs 21A, 22A, and 24A in a color corresponding to the function being displayed on the display unit 40.

In step SP42, the control unit 25A adjusts the brightness of the status LEDs 21A, 22A, and 24A to a value that corresponds to the function being displayed on the display unit 40.

In step SP51, the control unit 25A determines whether the display unit 40 is displaying the air conditioning function. If it is determined that the function is the air conditioning function (Yes), the control unit 25A proceeds to step SP52, and if it is determined that the function is not the air conditioning function (No), the control unit 25A ends the control without changing the illumination color and brightness of the status LEDs 21A, 22A, and 24A.

In step SP52, the control unit 25A adjusts the brightness of the status LEDs 21A, 22A, and 24A to a value that corresponds to the set temperature of the air conditioning function displayed on the display unit 40.

Please refer to Figure 11. Figure 11 is a time chart showing the control of the display brightness of the display unit 40 of the remote control device 1.

When the control unit 25A determines that the operation unit 30 has been operated at time t, it controls the brightness of the backlight LED 43 of the display unit 40 to an emphasis brightness L2 that is stronger than the normal brightness L1, and when it determines that the operation unit 30 has not been operated for a certain period of time thereafter, it controls the brightness of the backlight LED 43 of the display unit 40 to gradually dim from the emphasis brightness L2 toward the normal brightness L1. In this way, when the operation unit 30 has been operated, the remote control device 1 can improve the visibility of the display of the display unit 40 by setting the brightness of the display unit 40 to the emphasis brightness L2. Furthermore, when the operation unit 30 has not been operated for a certain period of time, the remote control device 1 can make the display of the display unit 40 less noticeable by returning the brightness of the display unit 40 to the normal brightness L1, thereby making the outside view visible and improving the interior design of the remote control device 1.
