- the switch to the see-through door may be performed by operating the lighting device 600 provided in the storage compartment.
- the lighting device 600 inside the storage room is operated, the interior of the dark storage room becomes bright. Therefore, the light inside the storage compartment is transmitted through the door to the outside, through which the inside of the storage compartment can be seen.

- the type of sensor for detecting the user's input may also vary.
- a refrigerator provided with a sensor 500 that detects a user's input for switching the see-through door may be provided.
- the sensor 500 is preferably a sensor for detecting the sound waves propagated by the medium.
- the user's input can be detected by detecting that the detected sound wave is a specific pattern.
- the sensor 500 means that the distance between the sound wave generation point and the sound wave sensing point can be spaced as long as the medium is continuous. That is, considering the total area of the general refrigerator door, it means that the distance between the sound wave generation point and the sound wave sensing point can be maximized as long as the continuity of the medium is maintained in the door of the refrigerator.
- the sound wave generation point may be a point at which the user applies an input for switching the see-through door

- the vibration of the medium is transmitted through the surface of the medium.
- the vibration may be a transverse wave transmitted through the surface of the medium. Therefore, as the sensing point moves away from the input point in the same medium, the attenuation width is relatively large.
- sound waves may be referred to as longitudinal waves transmitted through the inside of a medium. Therefore, the attenuation width of the sound wave is very small. Therefore, considering the size of the refrigerator, it may be more effective to detect the sound waves transmitted through the inside of the medium rather than the vibration transmitted through the surface of the medium.

- an additional device such as a touch panel is mounted on the front panel. This means that problems such as high cost, complexity, and durability degradation due to the touch panel can be prevented in advance.
- the entire front panel can be extended to the knock input area.
- the front panel is a medium through which sound waves are transmitted by a user's input. That is, it is preferable that the user applies an input to the front panel exposed to the front of the door and detects the sound wave transmitted by the front panel by the sensor.
- the sensor may comprise a sensor device, in particular a microphone, for sensing sound waves transmitted through the medium.
- the sound waves transmitted by the front panel are transferred to the microphone through a new medium, air. Therefore, it may be very important to shield the sound wave transmission space between the medium and the microphone from the outside. This is because, if such a shielding or closed space is not provided, external noise can be input into the microphone. Therefore, as will be described later, close contact between the microphone module high including the microphone and the front panel and its maintenance are very important. In addition, it is important that the support member for supporting such a microphone is also continuously receiving a force in the close direction. That is, the support member may also be in close contact with the front panel.
- the user it is preferable to allow the user to apply a knock input through the center portion of the door which is switched to the see-through and to sense the user's input through a sensor provided at the edge of the door which is not switched to the see-through.
- the portion to which the knock input is applied and the portion to be sensed form a continuous medium through a single front panel.
- the change in medium means that the deviation for the same input is very large as the knock input generation point is changed. Therefore, the accuracy of sensing is very low.
- an input applied to a medium different from the front panel can be determined to be a normal knock input.
- the shock applied to the other part of the refrigerator may be vibration of the refrigerator itself.
- the entire refrigerator may vibrate due to various causes such as vibration of the refrigerator caused by a refrigeration cycle drive or vibration caused by external force applied to the refrigerator itself.
- vibration of the refrigerator may be transmitted through the front panel to affect the sensor.
- the front panel itself can not but vibrate. Therefore, when detecting the vibration of the above-described medium itself, a situation in which the self-vibration of the refrigerator as a normal knock input may be detected.
- the attenuation width of the sound waves transmitted along the heterogeneous media is relatively very large.
- sound waves generated by the impact applied to other parts of the refrigerator other than the front panel may be sufficiently attenuated while being transmitted through various media. Therefore, when the knock input is detected by detecting the sound wave, malfunctions due to shock or vibration applied to portions other than the front panel may be significantly reduced. That is, when a microphone for detecting sound waves is used, since the refrigerator is relatively insensitive to vibration of the refrigerator, it is possible to significantly reduce recognition of the refrigerator's own vibration as a normal knock input.
- the refrigerator may include a sensor 500, a main controller 700, and an illumination device 600 that detect a user input for switching the through door.
- the sensor 500 may be provided to detect a knock input input by a user on the front of the door, for example, the front panels 271 and 471 of the subdoors 200 and 400. That is, the front panel may be provided to detect a knock input applied by the user.
- the main controller 700 controls the lighting device 600 to operate. Therefore, the see-through door switching is made as the inside of the storage compartment becomes brighter.
- the senor 500 may include a sensor device that senses a see-through switching input input by a user.
- the sensor 500 may include a microphone 510 for detecting sound waves as a sensor element. That is, it is preferable to include a microphone 510 for detecting the sound wave transmitted through the inside of the medium rather than detecting the vibration of the medium itself.
- the microphone 510 may detect sound waves caused by external noise as well as sound waves detected by the knock signal of the user. The latter sound waves or vibrations can be called noise. Therefore, it is necessary to structurally prevent such noise from being input to the microphone 510.
- the microphone 510 is preferably provided to be in close contact with the medium.
- the front panel 271, 471 is preferably provided to be in close contact with. Therefore, a mounting member or a supporting member for closely contacting the microphone 510 is required. Specific embodiments thereof will be described later.

- the refrigerator is generally provided with a door switch 800. That is, it can be seen whether the door of the refrigerator is opened or closed through the door switch 800.
- the door switch When the door is opened, the door switch is turned on to operate the lighting device 600 in the storage compartment. When the door is closed, the door switch is turned off to stop the lighting device 600 in the storage compartment.
- the on state and the off state of the door switch may be reversed.
- the operation relationship between the door switch 800 and the lighting device 600 may be performed independently of the control unit 700. Of course, the control unit 700 may grasp the closed and open state of the door through the door switch 800, it will be possible to control the lighting device 600 through this.
- the control method of the door switch 800, the main controller 700 and the lighting device 600 can be presented from two viewpoints.
- the lighting device 600 may include a main lighting device 610 and a sub lighting device 620.
- the main controller 700 may operate the lighting device 600, in particular the main lighting device 610, to switch the see-through door. That is, the see-through door switching is preferably on the premise that the main door is closed. Therefore, the main control unit 700 is controlled to operate the main lighting device 610 in spite of the on-state (door closed state) of the door switch 800 by the determination of the normal see-through switching input. As long as the door is not opened, the operation of the main lighting device 610 may be controlled through a see-through door switching algorithm. For example, the brightness of the main lighting device may be controlled to become brighter. In addition, the main lighting device can be controlled to stop the operation after a certain time operation. In other words, it may be controlled to turn off the lighting device after a certain time.
- the main main lighting device 610 may be switched to a general control algorithm. That is, the main lighting device 610 may be controlled to always operate when the main door is opened. Of course, if the open state is maintained for an excessively long time, an alarm may be generated and the main lighting device 610 may be controlled to be turned off.

- the main controller 700 may switch the subdoor to the see-through door by operating the sub illumination device 620 based on the determination of the normal see-through door switching input.
- the sub-illumination device 620 is preferably controlled to operate for a predetermined time. Even when the user opens the subdoor, the sub illumination device 620 may be continuously operated when the sub door is within the predetermined time.
- the main control unit 700 detects the opening of the main door through the door switch during the see-through door switching of the sub-door, it is preferable to control to stop the operation of the sub-illuminator 620.
- the main controller 700 may determine whether a normal see-through door switching signal is input through a signal input through the sensor 500. That is, the main controller 700 may directly determine whether it is a normal signal or noise. However, in this case, an overload problem of the main controller 700 may occur, and a noise effect due to the signal line itself may increase due to the distance between the sensor 500 and the main controller 700.
- the sensor 500 is preferably provided on the front panels 271 and 471.
- the main controller 700 is generally provided on one side of the cabinet 10 rather than the door. Therefore, the distance between the sensor 500 and the main control unit 700 is long, which means that the length of the signal line is longer. This means that the normal see-through switching signal may be contaminated due to noise through the signal line and input to the main controller 700. Therefore, there is a problem that the recognition rate of the see-through door switching signal is inevitably lowered.
- the sensor includes a microphone as a sensor element
- the signal output by the microphone is generally mV units
- the main controller 700 generally receives a V unit signal. Therefore, it is not desirable to determine whether the main control unit 700 is a normal see-through switching signal due to the scale difference of the physical signal.
- refrigerators are electronic devices that use high voltage / high current. Therefore, the electrical noise generation amount is relatively large. This means that the mV signal output by the microphone may be more vulnerable to electrical noise.

- the module microcom 540 determines a knock on signal through signals detected by the microphone 510. .
- the main controller 700 may send a signal indicating that a normal knock on input has been applied, otherwise it may not send a signal.
- the module microcomputer 540 when it is determined that the module microcomputer 540 is the knock-on signal, it can send a signal of 5V to the main controller 700. In the opposite case, a signal of 0 v can be sent. The latter can be said to not send a signal.
- the main controller 700 since the main controller 700 receives only the knock on signal input, the main controller 700 does not perform a separate determination on this. Through this, it is possible to minimize the influence of noise caused by the signal line between the main controller 700 and the module microcomputer 540. Similarly, the module microcomputer 540 may receive a signal minimized through a modular microphone and determine whether to knock on. Therefore, the recognition rate can be secured accurately.

- the second knock signal may be recognized as the next first knock signal. Therefore, when the third knock signal is applied again within 600 ms, the second knock signal and the third knock signal are recognized as normal knock inputs. Therefore, 10 seconds from the third knock signal recognition can be controlled to keep the lighting device on. That is, when the normal knock signal is continuously recognized, the on state time of the lighting apparatus may be continuously extended.
- the normal two knock inputs are continuously recognized as the normal knock input signal, thereby ensuring the reliability of the knock input to the user.
- the lighting device may operate more than necessary when the user consistently applies a normal knock input as a joke.
- Fig. 22 shows another example of the control method at the time of knock continuous generation.
- the second knock signal is generated within 600 ms after the first knock signal is generated, for example, it is recognized as a normal knock input and the lighting device is turned on.
- the lighting apparatus may be controlled to maintain, for example, 10 seconds on during normal knock input.
- the second knock signal Recognizing the normal knock input via the second knock signal, the second knock signal will determine the time interval at which the next third knock signal is applied. For example, if a third knock signal is applied after a 600 ms interval, it may be recognized as a normal knock off signal. That is, when the lighting device is turned on through the second knock signal and the third signal is applied after the 600 ms interval, it can be recognized as a normal knock off input. On the other hand, if the third signal is applied within 600 ms, this third signal can be ignored.
- the fourth signal can be recognized as a knock off input. Therefore, when the fourth signal is recognized, the lighting device can be controlled to be turned off.
- the fifth signal after the fourth signal is applied within 600 ms, the fifth signal and the sixth signal may be recognized as normal knock-on inputs and controlled to turn on the lighting again.
- the lighting apparatus may be controlled to repeat on / off. Through this control method, it is possible to relatively reduce the time that the lighting device is continuously turned on than the above-described embodiment.
- Fig. 23 shows another example of the control method at the time of knock continuous generation.
- the knock-off input is not required, and basically, when the lighting device is on, the on state can be maintained for a set time.
- a series of operations takes, for example, 5 seconds, the lighting device more than necessary. May cause problems.
- the lighting device can be controlled very simply and simply in spite of the continuous knock-on input, and the durability can be prevented from being degraded due to frequent on / off repetition of the lighting device.
