Abstract
The utility model relates to a warning device. A fridge battery-conserving alarm is characterized in that the alarm comprises a shell and a control circuit positioned in the shell and the control circuit comprises a photoconductive resistance RL, a light-controlled time delay circuit and a modulation acoustic generating circuit. When the fridge gate is not closed for a long time, the battery-conserving alarm arranged in the fridge produces warning sound to warn the host to take attention and the fridge gate is closed timely, thereby saving the electric.
Description
The device technical field
The utility model relates to a kind of warning device, relates to a kind of refrigerator economize on electricity alarm specifically.
Background technology
At present, family uses the quantity of refrigerator more and more, and the refrigerator open overlong time causes scattering and disappearing of cold air easily, like this, the start-stop ratio of refrigerator is increased, and strengthens the consumption of electric energy.
Summary of the invention
At above deficiency, the utility model purpose is to provide a kind of refrigerator economize on electricity alarm, and when refrigerator doors was not closed for a long time, the economize on electricity alarm that is placed on refrigerator inside will send chimes of doom and remind owner to note.
To achieve these goals, the technical solution of the utility model is: refrigerator economize on electricity alarm, it is characterized in that being made up of housing and control circuit, control circuit is positioned at enclosure interior, and control circuit is made of photo resistance RL, optically controlled delay circuit, modulation type sound generating circuit.
Described control circuit is positioned at enclosure interior.
Described control circuit is made of photo resistance RL, optically controlled delay circuit, modulation type sound generating circuit.
Described control circuit is provided with switch.
The utility model utilizes control circuit, it is made of photo resistance RL, optically controlled delay circuit, modulation type sound generating circuit, realize when refrigerator doors is not closed for a long time, the economize on electricity alarm that is placed on refrigerator inside will send chimes of doom and remind owner to note, timely closing refrigerator door, thereby using electricity wisely.
Description of drawings
Fig. 1 is the utility model control circuit figure.
The specific embodiment
As shown in Figure 1, NAND gate 1 is formed optically controlled delay circuit with photo resistance RL, delay cell R2, C1.When refrigerator open or door were not closed tight, it is a lot of that the illuminating lamp of establishing in the refrigerator reduces the resistance of photo resistance RL, and the dividing potential drop of RP1, R1 and RL makes the current potential of node near zero level, but owing to the voltage on the C1 can not suddenly change, so NAND gate 1 input still is a high level.Along with the charging of C1, R1, the input current potential of NAND gate 1 descends gradually, and when current potential dropped to the transfer valve threshold voltage that makes NAND gate 1 and is 1/2Vdd, NAND gate 1 output high level ended VD2, and at this moment, sound equipment produces circuit worker group and also produces chimes of doom.Therefore, as long as the time of opening the door is controlled at delay time interior (about 15 seconds) and in time closes the door,, delay time for charging next time and prepare just C1 can discharge rapidly by VD1, R1 and RP1.Meanwhile, VD2 conducting clamper locking warning circuit.Simultaneously, regulate the sensitivity that RP1 can change optically controlled delay circuit.
Claims (4)
1, refrigerator economize on electricity alarm is characterized in that being made up of housing and control circuit, and control circuit is positioned at enclosure interior, and control circuit is made of photo resistance RL, optically controlled delay circuit, modulation type sound generating circuit.
