The present invention relates to a refrigerator having a monitoring device, and more particularly, to a refrigerator capable of detecting and alarming the risk of theft and fire.

Refrigerators are indispensable in modern life and are provided in every home. The function of the conventional refrigerator is limited only to the storage and preservation of food, and at most, the outer wall of the refrigerator is used as a bulletin board in consideration of frequent use by family members. By the way, the refrigerator is usually located near the kitchen, and the kitchen of the modern house is a good location for monitoring the change of the various points in the house, and also easy to detect the fire or gas leakage. The refrigerator has a larger volume and wider outer surface than other items in the house, making it an excellent addition to additional functions. The refrigerator is also well suited for attaching monitoring devices that require continuous operation, as they are always powered on. .

It is therefore an object of the present invention to provide a refrigerator having a monitoring device utilizing the proper installation position of the refrigerator cabinet and its outer surface.

The object of the present invention is to provide a refrigerator, comprising: a sensing unit for detecting a predetermined change around the refrigerator, an alarm unit for informing an alarm, a selection unit for selecting a monitoring function, and a monitoring function by the selection unit. If it is selected is achieved by the refrigerator characterized in that it comprises a control unit for controlling to display a predetermined alarm in the alarm unit in accordance with the detection result.

Here, the detection unit, an infrared sensor for detecting infrared rays, an ultrasonic detector for detecting a moving object, a noise detector for detecting a noise of a predetermined size or more, a vibration detector for detecting a vibration of a predetermined size or more, a fire generation detector for detecting a fire And a gas leak detector.

The alarm unit may generate an alarm sound and an alarm light.

On the other hand, when there is no person at home, the selection unit includes a telephone number input unit for entering a phone number so that a predetermined place by phone to notify the danger of fire, disaster and theft, or to ask the nearest police or fire department to help The alarm unit includes a telephone line connection unit to which a telephone line is connected, and the control unit includes a memory unit for storing the telephone number and a predetermined alarm message, and the telephone number is connected to the telephone number through the telephone line connection unit according to a detection result of the detection unit. It is desirable to send an alert message.

And in order to prevent the selection or release of the monitoring function to be operated by unauthorized persons, the selection unit preferably includes a locking device for limiting the operation of the selection unit. This lock can be implemented as a password input device. In this case, the selection unit includes a password input unit for storing a password in the memory unit, when selecting a monitoring function of the selection unit, the selection unit also inputs a password, and the control unit inputs the password and the selection unit. The lock function can be realized by comparing and confirming the password stored in the memory unit.

On the other hand, when the monitoring function is selected, the control unit delays the display of the alarm through the alarm unit for a predetermined time when the monitoring function is selected so that the person operating the selection unit is immediately detected to prevent unnecessary alarms. desirable.

The sensing unit may be detachable from the refrigerator main body to change the sensing direction and the sensing position of the sensing unit.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the refrigerator according to the preferred embodiment of the present invention has a refrigerator main body 1 and a door 11 at the front thereof, and an infrared sensor 21 and a gas at the surface of the door 11. The leak sensor 22, the buzzer 41, and the selection part 5 are provided. Moreover, the telephone line connection part 42 connected to a telephone line is provided in the side wall of the main body 1.

FIG. 2 is a control block diagram of a monitoring function according to the embodiment of FIG. 1. The detection unit 2 detects a predetermined change around the refrigerator and sends the result to the control unit 3, and the selection unit 5 monitors. The function is selected and the control unit 3 is informed of the selection. When the monitoring function is selected by the selection unit 5, the control unit 3 sends a predetermined alarm to the alarm unit 4 according to the detection result of the detection unit 2, and the alarm unit 4 sends the control unit 3 from the control unit 3. Display the received alarm.

In the present embodiment, the sensing unit 2 is composed of an infrared sensor 21 and a gas leak sensor 22, the infrared sensor 21 detects infrared rays of a predetermined intensity or more, for example, intruders enter a certain area In case of intrusion detection, the gas leak sensor 22 detects propane gas or liquefied natural gas above a predetermined concentration. The infrared sensor 21 and the gas leak sensor 22 respectively transmit the detection result to the control unit 3.

The selector 5 selects an on / off operation of the monitoring function, selects an infrared sensor function and a gas leak sensor function as detection functions, selects an alarm sound function and a telephone notification function as alarm functions, respectively, and controls the selection result. 3) Inform. In addition, the password input unit 51 and the telephone number input unit 52 are included, and the input result of the password input unit 51 and the telephone number input unit 52 is transmitted to the controller 3.

The alarm unit 4 is composed of a buzzer 41 and a telephone line connection unit 42, the buzzer 41 generates an alarm sound according to the information sent from the control unit 3, and the telephone line connection unit 42 is connected to the telephone line and the control unit ( 3) is connected so that the control section 3 can send the corresponding message to the telephone number stored in the memory section 31.

The control unit 3 controls the buzzer 41 of the alarm unit 4 to generate an alarm sound when the alarm sound function of the selector 5 is selected according to the information sent by the sensor 2. When the telephone notification function of 5) is selected, the corresponding message is transmitted to the telephone number stored in the memory unit 31 via the telephone line connection unit 42 of the alarm unit 4. Then, the password entered by the password input unit 51 and the telephone number input by the phone number input unit 52 are stored in the memory unit 31, and the password entered by the selector 5 is confirmed.

3 is a plan view of the selector 5 according to the present embodiment, on the left side, a monitoring function selection / release button 501 for selecting a monitoring function, an infrared sensor selection / release button 502 for selecting a detection function, and a gas Leak sensor select / cancel button 503, alarm sound select / cancel button 504 to select alarm function, telephone notification select / cancel button 505, password change button 506 to change password and telephone number There is a phone number input button 507 for the input and change of, and on the right there are numeric buttons 508 for entering a phone number and password.

4 is a flowchart illustrating the operation of the monitoring function of the refrigerator according to the present embodiment. First, after the power supply of the refrigerator is connected, it is first checked whether the monitoring function of the selecting unit 5 is selected (S10). When the monitoring function is selected, it is checked whether at least one of the detection functions selected by the selection unit 5 has detected an abnormal situation (20). When at least one of the detection functions selected by the selection unit 5 detects an abnormal situation, the selection unit 5 checks the selected alarm function. First of all, if the alarm sound is selected among the alarm functions (S30) and then the alarm sound is selected (S31). If the telephone notification is selected among the alarm functions again (S40), and then the telephone notification is selected, the telephone is connected in the order of the telephone numbers stored in the memory unit 31 of the controller 3 (S41).
