Embodiment 1

[0016] Such as figure 1 As shown, if the lighting is a small light bulb powered by 220V, the alarm part is composed of a voice alarm circuit and a matching speaker 14. The 220V voltage is originally used for the lighting of the refrigerator, and the power is drawn from both ends of the lighting to supply power to the voice alarm circuit. The voltage integrated voice control circuit 13 is not powered, when the door is opened, the switch 11 is closed, the door light 12 is on, the RC step-down integrated voice control circuit 13 is energized, and the speaker 14 voice prompts; the door is still not closed or closed laxly after a fixed time delay , the door light 12 continues to be on, and the voice of the loudspeaker 14 continues to alarm until the door is closed and the switch 11 is disconnected again.

Embodiment 2

[0018] figure 2 Among them, if the lighting uses 12V voltage to power the LED lights, the alarm part is composed of a voice alarm circuit and a matching speaker 24, but the voice alarm circuit uses a linear voltage regulator integrated voice control circuit 23, so that it can be reduced by resistance and capacitance. The 220V voltage is originally used for the lighting of the refrigerator, and the power is drawn from both ends of the lighting to supply power to the voice alarm circuit. When the door is closed, the refrigerator door switch 21 is disconnected, and the door light 22 and the linear voltage regulator Integrated voice control circuit 23 is not energized, and when the door is opened, switch 21 is closed, and door light 22 is bright, and linear voltage regulator integrated voice control circuit 23 is energized, and loudspeaker 24 voice prompts; Lamp 22 continues to be bright, and loudspeaker 24 voice continues to report to the police, until the door is closed, and sw...

Abstract

The invention discloses a mechanical type refrigerator door state alarm device. The mechanical type refrigerator door state alarm device is composed of a voice alarm circuit and a matched loudspeaker, wherein the voice alarm circuit is in parallel connected to the two ends of a lighting lamp; the voice alarm circuit is used for supplying power to the loudspeaker. When the refrigerator door is not closed or not closed tightly, voice promotion and alarm can be generated. The mechanical type refrigerator door state alarm device is small in size, low in cost, free of needs of changing a refrigerator structure and a circuit, and convenient to mount.

Description

technical field [0001] The invention relates to the field of mechanical refrigerators. Specifically, the utility model relates to a voice prompt and alarm device for opening the door of a mechanical refrigerator refrigerating room. Background technique [0002] At present, smart electronically controlled refrigerators are equipped with door opening status display and door opening alarm prompt, but the refrigerators produced by many manufacturers are still mainly mechanical refrigerators, and generally do not have door status display and alarm prompt. If the door of the refrigerator is not closed or closed tightly, it will cause the refrigerator to work all the time, resulting in waste of energy; at the same time, the cooling effect will be reduced, resulting in food deterioration. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned shortcomings of the prior art, and provide a door state prompting and alarming device. ...
