2 is a front view illustrating a light emitting unit and a light receiving unit installed at a peripheral area of a cold air discharge port of a freezer compartment and / or a refrigerating compartment according to an embodiment of the present invention, and FIG. 3 is a view illustrating a light emitting unit and a light receiving unit according to an embodiment of the present invention. The block diagram is shown.

As shown in Figure 2 and 3, the cold air duct blocking device of the refrigerator according to the first embodiment of the present invention is a sensor 105, the signal conversion unit 130, the control unit 140 and the alarm means 150 It includes. The sensor 105 includes a light emitting unit 110 and a light receiving unit 120 installed in the peripheral region of the cold air outlet 100 located in the freezer compartment and / or the refrigerating compartment of the refrigerator. The light emitting unit 110 is located at one side of the peripheral region of the cold air outlet 100, and the light receiving unit 120 is located at the other side of the peripheral region of the cold air outlet 100.

The light emitting unit 110 emits light having a predetermined wavelength, for example, infrared rays or lasers, into the internal space of the refrigerator, and the light receiving unit 120 includes a cadmium cell (CDS), a photodiode, or a phototransistor. The irradiated light is detected using a device that responds to the light intensity, such as a transistor).

The light detected by the light receiver 120 is converted into an electrical signal by the signal converter 130. The electrical signal converted by the signal conversion unit 130 is transmitted to the control unit 140, the control unit 140 controls the alarm means 150 by turning on / off the switch (S).

When the light emitted from the light emitting unit 110 is detected by the light receiving unit 120, the control unit 140 does not operate the alarm means 150 by keeping the switch (S) in the off state. On the contrary, the control unit 140 intersects the path of the light by placing an object such as a storage container or food between the paths from which the light emitted from the light emitting unit 110 is detected by the light receiving unit 120 to prevent the signal conversion unit ( If the electrical signal is not transmitted from 130 to turn on the switch (S) to operate the alarm means 150.

The alarm means 150 may operate to stimulate visual or auditory hearing. For example, the alarm means 150 determines that cold air does not circulate smoothly when light is not detected by the light receiving unit 120, and emits light such as a light emitting diode (LED). To stimulate the user's vision.

On the other hand, the alarm means 150 may stimulate the user's hearing by broadcasting that the cold air is not smoothly circulated through the speaker mounted in the refrigerator.

Next, an operation method of the alarm device according to an embodiment of the present invention will be described. Figure 4 is a flow chart for explaining the operation of the alarm device according to an embodiment of the present invention.

As shown in Figure 4, the operating method of the alarm device according to the first embodiment of the present invention includes the step of irradiating light from the light emitting unit 110 of the sensor 105 (S210).

The light irradiated from the light emitting unit 110 is detected by the light receiving unit 120 having the sensing element (S220). When the user of the refrigerator places an object such as a storage container or food on a path of light that proceeds to the light receiving unit 120, the light receiving unit 120 does not detect the light, or the light is detected due to a weak signal. The conversion unit 130 may not be converted into an electrical signal. Therefore, the control unit 140 switches the switch S from the off state to the on state (S230) to operate the alarm means 150. As a result, the alarm means 150 informs the user visually or audibly that cold air is not circulated smoothly (S240).

On the contrary, when the light is detected at the light receiving unit 120 and the signal conversion unit 130 converts the light signal into an electrical signal, the control unit 140 controls the switch S to be in an off state so that the alarm device 140 It doesn't work.

As shown in FIG. 7, the touch button 300 protrudes from the peripheral area of the cold air discharge port 100 when the user puts an object such as a storage container or food into the freezer compartment and / or the refrigerating compartment of the refrigerator. It can be moved in the opposite direction of the object (S410). When the pressure of the object is sensed by the pressure sensor 310 by the movement of the touch button 300 (S420), the pressure signal is converted into an electrical signal by the signal converter 320.

The control unit 330 receives the electrical signal to turn on the switch 340 (S430), and operates the alarm means (S440). As a result, the alarm means 340 visually or audibly informs the user that cold air is not circulated smoothly.

On the contrary, when the pressure of the object is not detected by the pressure detecting sensor 310 or when the detected pressure is weak enough not to be converted into an electrical signal by the signal converting unit 320, the control unit 330 switches (S). ) Is off and the alarm means is not operated.
