Abstract

The utility model relates to a refrigerator door closing reminder. The utility model is characterized in that the reminder comprises an upper door opening paired button (4) installed on the lateral side of the magnetic seal (2) of a refrigerator door (3), a lower door opening paired button (5) and a battery (8) inside a reminder box (1), a direct current buzzer (7), a dichromatic light emitting diode (6) and a time-delay switch (9) which are connected together through a line. The time-delay switch (9) and the direct current buzzer (7) are connected with each other in series. The utility model can automatically detect the close status of the refrigerator door, and the status can be displayed through an indicator lamp. If a refrigerator door is not closed properly, the reminder can remind the attention of the owner through the sound and light alarm. The line cost is low, and the installation is convenient and feasible. The users can easily reformed the prior refrigerator which can save worry and save power.

Description

The refrigerator reminiscences of closing the door

Technical field

The utility model relates to commodity, is a kind of refrigerator reminiscences of closing the door specifically.

Background technology

Refrigerator has become the necessity in people's daily life, relies on its refrigeration to make food or article keep low temperature, is used for keeping the performance of food or other article, but refrigerator need be paid the consumption of electric power and keeps this effect.Refrigerator doors relies on the magnetic strip of paper used for sealing to prevent that cold air from leaking, if when people open refrigerator doors at ordinary times, does not note not shutting the door, making door leave the slit does not but note, the refrigeration of refrigerator is greatly reduced, not only be difficult to keep the low temperature in the refrigerator, power consumption also can significantly increase.Yet, notice when allowing man-hour whether refrigerator doors shuts a burden that can allow refrigerator become the people house, and whoever can not propose such requirement to the user.

Summary of the invention

The purpose of this utility model provides a kind of refrigerator of detection alarm automatically reminiscences of closing the door.

The refrigerator described in the utility model reminiscences of closing the door, it is characterized in that: connected and composed by circuit by battery, direct current buzzer, dichromatic LED, delay switch in upward-acting door duplex button, downward swing door duplex button and the reminiscences box in the magnetic strip of paper used for sealing outside that is installed in refrigerator doors, wherein delay switch and direct current buzzer are in series.

The connection line of described reminiscences is: upward-acting door is often opened button, downward swing door and is often opened a A in button, the dichromatic LED, current-limiting resistance and battery and form a series loop, after the normally closed button of upward-acting door, the normally closed button parallel connection of downward swing door with delay switch, direct current buzzer be in series the back with battery form another loop, an end is connected with the positive pole of battery after the normally closed button of upward-acting door, the normally closed button parallel connection of downward swing door, and the other end also is connected with the anode of another B of dichromatic LED.

The utility model can detect the closed condition of refrigerator doors automatically, and shows by indicator lamp, does not shut then if any a refrigerator doors and reminds owner to note by sound and light alarm.Line cost is cheap, and is easy for installation feasible, and the user can easily transform existing refrigerator voluntarily, the power saving of saving worry.

Description of drawings

Fig. 1 is the utility model electrical block diagram,

Fig. 2 is the utility model installation site schematic diagram.

Among the figure: 1-reminiscences box, 2-magnetic strip of paper used for sealing, 3-refrigerator doors, 4-upward-acting door duplex button, the normally closed button of 4-1-upward-acting door, button is often driven in 4-2-upward-acting door, the normally closed button of 5-1-downward swing door, 5-2-downward swing door is often driven button, 5-downward swing door duplex button, 6-dichromatic LED, an A in 6-1-dichromatic LED, the another B in 6-2-dichromatic LED, 7-direct current buzzer, 8-battery, 9-delay switch, 10-current-limiting resistance.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further specified: the refrigerator reminiscences of closing the door as shown in Fig. 1,2, it is characterized in that: connected and composed by circuit by the battery 8 in the upward-acting door duplex button 4 in magnetic strip of paper used for sealing 2 outsides that are installed in refrigerator doors 3, downward swing door duplex button 5 and the reminiscences box 1, direct current buzzer 7, dichromatic LED 6, delay switch 9, wherein delay switch 9 is in series with direct current buzzer 7.

In Fig. 2, the connection line of described reminiscences is: upward-acting door often opens that button 4-2, downward swing door often leave a A6-1 in button 5-2, the dichromatic LED, current-limiting resistance 10 forms a series loop with battery 8, be in series back with delay switch 9, direct current buzzer 7 after the normally closed button 4-1 of upward-acting door, the normally closed button 5-1 of the downward swing door parallel connection and battery 8 another loops of formation, an end is connected with the positive pole of battery 8 after the normally closed button 4-1 of upward-acting door, the normally closed button 5-1 of the downward swing door parallel connection, and the other end also is connected with the anode of another B6-2 of dichromatic LED.

The connection of circuit is the normal closing state of refrigerator doors among Fig. 2, and the duplex button is pressed by refrigerator doors 3, and normally closed switch disconnects, the normal open switch closure.Find out easily under normal refrigerator doors 3 closing state, dichromatic LED 6 is a kind of color of demonstration of the status indicator lamp of refrigerator doors 3 just, the color of an A6-1 in the dichromatic LED just, direct current buzzer 7 outages this moment, in case having any one often to drive button is released and disconnects, an A6-1 in the dichromatic LED will extinguish, the normal indication decoloration of corresponding status indicator lamp, and when the normally closed button of this duplex button is closed simultaneously, another B in the dichromatic LED will switch on and light, the warning indication look of corresponding status indicator lamp is luminous, delay switch 9 is started working simultaneously, after through default delay time, if delay switch 9 still has electric current to supply then delay switch 9 conducting immediately, direct current buzzer 7 must be established the chimes of doom that starts out by cable, reminds owner's refrigerator doors still to be in not closed condition.

The space is all left in the outside at the magnetic strip of paper used for sealing 2 of refrigerator usually to the refrigerator edge, can be used for installing the duplex button, and the lead that connects button is connected in the reminiscences box 1 along this space cabling.When refrigerator doors 3 was normally closed, the shock-resistant button of custom-designed long handle just in time was in the state that is pressed, this moment the normal opened contact closure, and normally closed contact disconnects, this state makes an A6-1 of dichromatic LED be lighted and direct current buzzer 7 sounding not.Expression refrigerator doors 3 is closed normally.When refrigerator doors 3 was opened, the button on this was released, make an A6-1 of dichromatic LED extinguish, and delay switch 9 was started working, and represented that through direct current buzzer 7 sounding after the scheduled time refrigerator doors 3 do not close.Thereby the effect of playing automatic detection refrigerator doors 3 closed conditions and reporting to the police automatically
