Abstract

The utility model relates to a reminder when a refrigerator door is forgotten to be closed, and has the purpose to solve the problem that because a refrigerator door is forgotten to be closed or not be closed tightly, the electrical energy is wasted, and the food is degenerated. As a circuit attached in a refrigerator, the reminder consists of a refrigerator door switch, a time delay circuit and a voice prompting module. When the refrigerator door is not closed tightly, a door switch contact is closed, and the power current triggers a voice circuit to work, thereby sending a prompt that the refrigerator door is not closed tightly, and thereby reminding people of closing the refrigerator door tightly.

Description

Refrigerator doors forgets to close reminiscences

Technical field

The utility model relates to a kind of refrigerator doors and forgets to close reminiscences.

Background technology

Present refrigerator has brought the convenience of many lives to the people, but the shortcoming that exists is: people's carelessness is forgotten when closing refrigerator doors, causes the food spoilage in the refrigerator, also makes the refrigerator long-term operation, wastes a large amount of electric energy.

The utility model content

The purpose of this utility model is to solve above-mentioned shortcoming, and provides a kind of simple in structure, convenient and practical refrigerator doors to forget to close reminiscences.

For achieving the above object, the technical scheme that adopts of dealing with problems is: on the basis of former refrigerator circuit, increase an accessory circuit, and by refrigerator door open-close, delay circuit, voice cue module is formed.When refrigerator does not shut, the door switch closing of contact, source current triggers sound circuit work by delay circuit, sends the voice suggestion of " refrigerator doors does not shut ".

The beneficial effects of the utility model:

Reminds people is in time shut refrigerator doors, and saves energy prevents food spoilage.

Description of drawings

Fig. 1 is a circuit diagram of the present utility model.

Among the figure, 1.---refrigerator door open-close; 2.---adjustable delay resistance; 3.---delay circuit; 4.---voice warning circuit.

Embodiment:

As shown in Figure 1, a kind of refrigerator doors forgets to close reminiscences, and 3. 1. described refrigerator door open-close link to each other with delay switch circuit, the work of control delay switch circuit, and 4. 3. delay switch circuit link to each other with voice warning circuit, the work of control voice warning circuit.When refrigerator did not shut, 1. door switch was connected, and delay switch circuit work triggers voice warning circuit work behind the time-delay certain hour.2. delay switch circuit delay time 3. can be regulated by adjustable delay resistance.

Claims

1. a refrigerator doors forgets to close reminiscences, form by refrigerator door open-close, delay switch circuit and voice warning circuit, it is characterized in that: 3. 1. refrigerator door open-close link to each other with delay switch circuit, the work of control delay switch circuit, 4. 3. delay switch circuit link to each other with voice warning circuit, the work of control voice cue module.

2. forget to close reminiscences according to the described refrigerator doors of claim 1, it is characterized in that: 2. delay switch circuit delay time 3. can be regulated by adjustable delay resistance.
