In the following detailed description of the preferred embodiments of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. In the drawings, like reference numerals are used throughout the drawings.

In addition, in the entire specification, when a part is referred to as being 'connected' to another part, it may be referred to as 'indirectly connected' not only with 'directly connected' .

1 is a block diagram showing functions of a remote controller according to an embodiment of the present invention.

Referring to FIG. 1, a remote controller 100 according to an embodiment of the present invention may include an input unit 10, a communication unit 20, and a mode switching unit 30.

Hereinafter, a remote controller 100 according to an embodiment of the present invention will be described with reference to FIG.

The input unit 10 may include at least one micro force sensor and may generate a control signal for controlling the operation of the controlled device 200 according to an input to the force sensor. Here, the controlled device 200 is an apparatus whose operation is controlled according to a control signal transmitted from the remote controller 100, and may be a household appliance such as a bidet or a TV.

The user can input the operation of the controlled device 200 desired by the user in a manner that the user presses the force sensor provided on the input unit 10 and presses the force sensor. The control signal for controlling the controlled device 200 can be generated.

Specifically, the input unit 10 may include a plurality of force sensors, and the plurality of force sensors may respectively generate different control signals. Thus, the user can control the operation of the bidet by selecting any one of the plurality of force sensors.

Further, with respect to the input to the force sensor, the input time for holding the pressure to the force sensor, the intensity of the input pressure and the advancing direction of the input pressure, etc., Can be input in a different manner. The control signal generated by the input unit 10 may vary depending on the input method of the force sensor.

The input unit 10 receives a desired operation from a user by using the force sensor. Therefore, the force sensor will be described with reference to FIG.

2, the force sensor 11 may have a structure in which two sheets of film 11a face each other in a layered structure, as shown in FIG. 2, A piezo-resistive material 11b may be disposed between the two films 11a.

The force sensor 11 detects the applied force F through a resistance value or a magnitude of a voltage across the force sensor 11 which varies according to the intensity of a force F applied to the force sensor 11 It may be to sense.

Specifically, when the force F is applied to the force sensor 11, the interval between the two films 11a becomes gradually narrower, so that the pressure-sensitive layer 11b comes into contact with each other. The area of the pressure-sensitive layer 11b abutting on the abutting pressure-sensitive layer 11b increases according to the magnitude of the force F applied to the force sensor 11. As the abutting area increases, the resistance of both ends of the force sensor 11 gradually decreases do. This is due to the piezoelectric effect, and as the magnitude of the force F applied to the force sensor 11 increases, the resistance at both ends of the force sensor 11 becomes smaller. Therefore, the force F inputted to the force sensor 11 can be sensed by measuring the change in the resistance value or the voltage across the force sensor 11.

2 (b) is a graph showing a change in voltage between both ends of a reference resistor connected in series with the force sensor 11. As the magnitude of the force applied to the force sensor 11 increases, the magnitude . This is because the resistance value across the force sensor 11 decreases as the magnitude of the force applied to the force sensor 11 increases, so that the magnitude of the voltage across the reference resistance increases according to the voltage distribution law.

2 (b), since the voltage value across the reference resistance increases in correspondence with the intensity of the force applied to the force sensor 11, the input unit 10 detects the force of the force sensor 11 11) can be distinguished and recognized. Therefore, the input unit 10 can generate various control signals according to the intensity of the force input to the force sensor 11, in addition to checking whether the input is simply input to the force sensor 11 , And can control the operation of the controlled device 200 in various manners using the same.

More specifically, control signal formation according to the intensity of the force input to the force sensor 11 will be described with reference to FIG.

3 shows the magnitude of the voltage across the reference resistance corresponding to the magnitude of the force applied to the force sensor 11. The magnitude of the force applied to the force sensor 11 is divided into three regions a , b, c). Since each of the regions has a corresponding voltage range (p, q, r), the input unit 10 senses a voltage value across the reference resistor and discriminates an area corresponding to the applied force intensity can do.

Therefore, the input unit 10 distinguishes the intensity of the force applied to the three regions according to the magnitude of the voltage between both ends of the force sensor 11, and transmits different control signals according to the intensity of the separated force .

For example, in the case of setting the toilet seat temperature of the bidet using the remote controller, generally, a method of repeatedly pressing the toilet seat temperature button may be utilized. However, if the force sensor is used, The toilet seat temperature can be set differently according to the strength of the toilet seat. That is, the input unit 10 distinguishes the intensity of the force pressing the toilet seat temperature button from "upper, middle, lower" and sets the toilet seat temperature to "high, middle, low" Quot; upper ", the toilet seat temperature is set to "high ", and if the strength of the force corresponds to the middle, the toilet seat temperature is set to middle. It is possible to generate a control signal which is set to "low ". In addition, if the force applied to the force sensor 11 is strong, the injection strength of the washing water is increased. If the applied force is small, the injection strength of the washing water is weakened. It can be set according to the strength of the force.

That is, according to the input unit 10 according to the embodiment of the present invention, different control signals can be generated according to the intensity of the applied force, so that the controlled device 200 Can be controlled. In FIG. 3, the case of dividing into three regions according to the strength of force is exemplified. However, the present invention is not limited to this, and the case of dividing into a plurality of regions may be included according to the strength of the force.

In addition, the input unit 10 may sense the direction of the force applied to the force sensor 11, and generate a control signal corresponding to the direction of the force. Fig. 4 (a) is a diagram for explaining the detection of the advancing direction of the force applied to the input section 10, which will be described below with reference to Fig. 4 (a). A plurality of force sensors 11 may be provided in the input unit 10 (f11-14, f21-f24, f31-f34, f41-f44).

D1, d2 and d3 in Fig. 4 (a) indicate the advancing direction of the force applied to the input section 10. Particularly, d1 is the force applied to the force sensor f32, And is distinguished from d2 in which a force is first applied to f21 and a force is sequentially applied to f22, f23, and f24. That is, the input unit 10 can sense the direction of the applied force from the force sensors that sequentially recognize the applied force, and can generate the control signal differently according to the traveling direction of the force.

Since the input unit 10 can know the information about the position of each force sensor in advance, it is possible to grasp the progress direction of the force sensor from the force sensor to which the current force is applied and the force sensor to which the force is immediately applied , A control signal corresponding to the detected direction of the force can be generated. For example, the position of the nozzle of the bidet may be adjusted according to the direction of the force sensed by the input unit 10, or the direction of the wind of the drying fan may be adjusted according to the direction of the force sensed by the input unit 10 And the like.

Also, unlike FIG. 4A, the direction of the force applied to the one force sensor can be measured and detected by using a single force sensor. Specifically, the resistance value of the decompression layer of the force sensor can be lowered for the region to which the force is applied, and the remaining portion can be kept constant. Therefore, the resistance distribution of the force sensor as a whole can be obtained from the measured values of the current sensor, the voltage sensor, and the like, and the direction of the force can be detected by extracting a region having a lower resistance value.

4 (b), a plurality of force sensors 11 constituting the input unit 10 are divided into a plurality of regions along the direction, and when a force is applied to a region corresponding to each direction It is possible to generate a control signal corresponding to the direction. That is, as shown in FIG. 4 (b), after a region of the input unit 10 is divided into up, down, right, and left, It is possible to generate a control signal corresponding to the control signal.

For example, when a force is applied to the force sensor corresponding to the up, a control signal for raising the washing water temperature of the bidet is generated, or when a force is applied to the force sensor corresponding to the right, So that a signal can be generated.

In this case, unlike FIG. 4 (b), one force sensor may be divided into a plurality of regions along a direction, and a control signal corresponding to the direction may be generated when a force is applied to the region corresponding to the direction . That is, since the resistance value is low with respect to the region to which the force is applied, a region having a low resistance value is extracted from the force sensor, and the region is determined as the region to which the force is applied. So that a corresponding control signal can be generated.

FIG. 5A shows an embodiment of the remote controller 100 according to the present invention, wherein the operation of the bidet is controlled by the remote controller 100. FIG. Here, the force sensors may be provided in button regions such as "+", "-", "cleaning", "bidet", "dry", "stop", "air" The control signal generated by the remote controller 100 may vary according to which force sensor is applied to the force sensor. The operation of the bidet may be controlled in response to a control signal generated by the remote controller 100. [

With respect to the application of the force to the button, in the case of the "+" button, for example, the temperature of the washing water or the temperature of the toilet seat may be increased according to the number of times of inputting of the "+" And it is also possible to vary the degree to which the temperature of the wash water or the temperature of the toilet seat rises according to the intensity of the force applied to the "+" button. As previously noted, the "+" button may be implemented by a force sensor, so that the intensity of the force applied to the "+" Therefore, it is also possible to generate a control signal for setting the temperature of the washing water or the temperature of the toilet seat corresponding to the strength of the force.

For example, after setting the strength of the force for the "+" button to "upper, middle, lower", and when the strength of the "upper" force is inputted, the temperature of the "washing water" And when the strength of the "upper" force is input, the "temperature of the washing water" is set to be increased by 5 degrees or the like. In addition, it is possible to generate a control signal for controlling the controlled device in various manners by sensing the intensity of the force applied to the force sensor.

Additionally, in the case of the "clean" button, it is possible to control the cleaning operation to clean the local portion of the user in accordance with the direction of travel of the force applied to the "clean" button. For example, when a force is applied in such a manner that the above "cleaning" button is swept downward, the position of the nozzle is moved back so that the point at which the washing water is sprayed to the body is moved back, It is possible to move the position forward to generate a control signal that causes the point at which the wash water is injected into the body to move forward. In addition, a control signal for controlling the controlled device can be generated in various manners by sensing the direction of the force applied to the force sensor.

Since the remote controller 100 uses the force sensor, the remote controller 100 can be realized to be waterproof even without a separate vinyl coating or the like.

In the case of the conventional remote control button, a groove is provided at the lower end of the button. When the button is applied with a force, the button is lowered by the force, and the control signal is generated by shorting or opening the circuit. At this time, since the water may flow into the grooves, an additional waterproof treatment such as a vinyl coating is required to use the remote controller 100 in a place with high humidity or high water.

However, in the case of the force sensor, since the button is implemented as a material having an elastic force for allowing the pressure-sensitive layer film to come into contact therewith, a separate groove for inputting the button is not required. In this case, water can be prevented from entering the interior of the remote controller 100 without a separate vinyl coating or the like.

Accordingly, since the remote controller 100 using the force sensor can easily perform the waterproof treatment, it can be widely used in a place where a waterproof function is required. In particular, the remote controller 100 may be suitable for use in a bidet used in a bathroom with a lot of water.

The communication unit 20 can transmit the control signal generated by the input unit 10 to the controlled device 200 by using wired or wireless communication. The remote controller 100 is separate from the controlled device 200 so that the controlled device 200 is required to transmit the control signal generated by the input unit 10 to the controlled device 200. [ And the like. The remote controller 100 includes a configuration of the communication unit 20 capable of providing a wired or wireless communication between the remote controller 100 and the controlled device 200, And transmits the control signal generated by the control unit (10) to the controlled device (200). At this time, the controlled device 200 may be provided with a receiving unit for receiving a control signal transmitted from the communication unit 20. [

The communication unit 20 may use infrared communication widely used in a TV remote control or the like in order to provide wireless communication between the remote controller 100 and the controlled device 200. In addition to the Wi- , Bluetooth, or the like, may be used to perform wireless communication with the controlled device 200.

Particularly, in the case of the infrared communication, the distance that the control signal can be received is as short as a few meters, and a control signal transmitted by the communication unit 20 of the remote controller 100 is transmitted by the receiver of the controlled device 200 The angle between the controlled device 200 and the communication unit of the remote controller 100 may be important.

Therefore, the communication unit 20 can be positioned at the lower end of the remote controller 100, and the communication unit 20 can be controlled by the control unit 200, The position and configuration of the communication unit 20 can be adjusted.

In particular, when the controlled device 200 is a bidet, the predetermined inclination may be any angle between 30 and 60 degrees, and preferably 45 degrees. Since the user mainly uses the remote controller 100 while the user is sitting on the bidet, the position of the communication unit 20 is set in consideration of the use state.

The mode switching unit 30 can switch the mode of the input unit 10 to the power saving mode in which the force sensor does not operate or the operation mode in which the operation of the force sensor is activated.

The mode switching unit 30 controls activation of a force sensor provided in the input unit 10, and the force sensor may be activated when power is applied. Therefore, the mode switching unit 30 distinguishes between the operation mode in which the remote controller 100 is used and the power saving mode in which the remote controller 100 is not used, so that only when the remote controller 100 is used, As shown in FIG. This is to prevent the controlled device 200 from operating when the force is unintentionally applied to the force sensor and to prevent power consumption due to activation of the force sensor.

In particular, when the operation life of the remote controller 100 is limited, for example, by using a battery as a power source, the operation life of the remote controller 100 can be increased by preventing power consumption by using the mode switching unit 30 There is an effect.

Here, the mode switching unit 30 may include an additional sensor or switch to receive an input for the mode switching, and the mode switching input may be implemented in various ways.

Hereinafter, a mode switching method of the input unit 10 according to an embodiment of the present invention will be described.

The mode switching unit 30 may include an electrostatic capacity sensor for detecting a change in static electricity caused by approach of a human body, The input unit 10 can be switched to the operation mode.

Generally, in order to use the remote controller 100, the remote controller 100 is held or touched by using a part of the user's hand or the like. At this time, if the capacitance sensor is used, human body approach to the remote controller 100 can be detected, so that it is possible to determine whether the user uses the remote controller 100 or not.

Specifically, the electrostatic capacitance sensor can sense a change in static electricity in the capacitance sensor according to the approach of a human body, and the amount of change in the static electricity can be gradually increased as a part of the human body approaches. Here, if the change amount of the static electricity increases to a predetermined value or more, the user can recognize that the remote controller 100 has been accessed for use of the remote controller 100. In this case, Mode to the operation mode.

Therefore, by using the capacitance sensor, the user can naturally activate the operation of the force sensor even if he or she touches or touches the remote controller 100 without performing any other operation such as pressing a separate switch.

The mode switching unit 30 according to another embodiment of the present invention senses the distance to a human body approaching the input unit 10 using an infrared sensor and detects a distance between the human body and the input unit 10 The input unit can be switched to the operation mode if the preset value is less than the predetermined value.

The human body may be detected not only by the capacitance sensor but also through the infrared sensor. The infrared sensor may include a light emitting unit for emitting infrared rays and a light receiving unit for sensing the reflected light reflected by the emitted infrared rays . Therefore, when the infrared ray emitted by the light emitting unit is reflected by the human body and is reflected, the light receiving unit senses the reflected light, and the time when the infrared ray is reflected and returned can be measured. Using the measured time and the speed of the infrared ray, the distance from the infrared ray sensor to the human body can be easily calculated.

Here, if the distance from the human body measured by the infrared sensor gradually approaches to a predetermined distance or less, it can be recognized that the user has approached the remote controller 100 for use of the remote controller 100 have. Therefore, the mode switching unit 30 can switch the input unit 10 from the power saving mode to the operation mode.

In addition, any sensor capable of sensing the approach of the human body, such as a light intensity sensor or a camera, can be utilized. If the sensor determines that the human body is approaching the remote controller 100, the system can be switched from the power saving mode to the operation mode.

The mode switching unit 30 may include an acceleration sensor for sensing the motion of the remote controller 100. The mode switching unit 30 may include an acceleration sensor for detecting a motion of the remote controller 100, The input unit 10 can be switched to the operation mode.

The acceleration sensor measures a change in acceleration according to the movement of the remote controller 100. The acceleration sensor measures the movement of the remote controller 100 in various ways such as an inertia type, a gyro type, a silicon semiconductor type, .

For example, the remote controller 100 may be provided to detach the remote controller 100 from a separate remote controller, and when the user removes the remote controller 100, the remote controller 100 moves in various directions . The acceleration sensor can detect a motion generated when the remote controller 100 is attached or detached, so that the mode switching unit 30 can switch the mode of the input unit 10 from the power saving mode to the operation mode. However, the present invention is not limited to the case where the remote controller 100 is detached from the remote control cradle. When the remote controller 100 is moved to use the remote control 100 and the acceleration sensor senses the movement, . ≪ / RTI >

Here, in order to prevent the remote controller 100 from being switched to the operation mode even when the remote controller 100 is accidentally touched, the operation mode is switched to the operation mode only when the movement of the remote controller 100 is detected to be equal to or greater than the predetermined value .

Accordingly, in the case of using the acceleration sensor, the mode of the input unit 10 can be changed by using the movement of the remote controller 100, which may naturally occur when the remote controller 100 is used, as in the case of using the capacitance sensor It is possible to switch to the operation mode.

The mode switching unit 30 may include a hall sensor for sensing a change in a magnetic field applied to the remote controller 100. When the remote controller 100 is detached from a remote controller cradle equipped with magnets, So that the input unit 10 can be switched to the operation mode.

Referring to the bidet 200 shown in FIG. 5 (b), the bidet 200 may include a remote control holder 260. The remote controller 100 according to an embodiment of the present invention may be located in the remote controller cradle 260, and a magnet may be provided in the remote controller cradle 260. The magnet may be provided to provide an adhesive force between the remote control cradle 260 and the remote controller 100. In order to determine whether the remote controller 100 is used or not by using the magnetic field generated by the magnet, Can be used.

Specifically, the remote controller 100 may be provided with a Hall sensor capable of detecting a change in magnetic field. When the remote controller 100 is located on the remote control cradle 260, a magnetic field of a predetermined magnitude can be continuously applied to the remote controller 100 by the magnet provided on the remote control cradle 260. However, when the user removes the remote controller 100 from the remote controller cradle 260 to use the remote controller 100, the magnetic field by the magnet is no longer applied to the remote controller 100, Can sense this.

Since the remote controller 100 is detached from the remote control cradle 260 when the hall sensor detects the detachment of the remote controller 100, May be switched from the power saving mode to the operation mode.

The mode switching unit 30 includes a mode switching force sensor and switches the input unit 10 to the operation mode when a pressure greater than a predetermined magnitude is applied to the mode switching force sensor . When the input unit 10 is in the power saving mode, only the mode switching force sensor is activated and the input unit 10 can be switched to the operation mode when pressure is applied to the mode switching force sensor. Furthermore, when the mode switching force sensor is pressed in the operation mode, the mode is switched back to the power saving mode, or in the operation mode, the mode switching force sensor is inactivated.

Here, the power switch for mode switching may be located in the handle of the remote controller 100. The remote controller 100 may be provided with a knob for easily gripping the remote controller 100, and the mode switching force sensor may be provided on the knob. In this case, when the grip portion is gripped to use the remote controller 100, the mode switching force sensor can be pressed at the same time, so that the remote controller 100 can be switched to the operation mode. To this end, the mode switching force sensor located at the handle portion may set the pressure of the predetermined magnitude to a magnitude of pressure enough to hold the handle portion. It is also possible to provide an illuminance sensor in place of the mode switching force sensor on the handgrip to switch the mode of the remote controller 100 to the operation mode. That is, when the user holds the handle, light may be blocked by the illuminance sensor, so that it is possible to detect whether the user is holding the handle by detecting whether the light is blocked.

In addition, the mode switching unit 30 may include at least one of the mode switching force sensor, the electrostatic capacitance sensor, the infrared sensor, the acceleration sensor, and the Hall sensor. The input unit 10 ) Can be switched. That is, the mode switching unit 30 may include not only the mode switching force sensor, the electrostatic capacitance sensor, the infrared ray sensor, the acceleration sensor, and the Hall sensor, but may also include a plurality of sensors, The controller 30 can determine whether to switch the mode of the input unit 10 using signals input from the plurality of sensors.

On the other hand, the mode switching unit 30 needs to switch the input unit 10 from the operation mode to the power saving mode. However, the mode switching unit 30 may switch the mode of the input unit 10 when the input to the force sensor is not longer than a preset time, To the power saving mode in the operation mode.
