FIG. 3 is a block diagram of the architecture system of the present invention.

In the figure: 1. a refrigerator body; 2. a proximity switch; 3. a human body induction module; 4. a refrigerator baffle plate; 5. a rotating seat; 6. a wind-up roll; 7. a motor; 8. a transparent night curtain; 9. a night curtain base.

Detailed Description

The first embodiment is as follows:

referring to fig. 1-3, the present invention provides a technical solution: automatic induction elevating gear of freezer night curtain, including freezer body 1, the bottom inner wall fixedly connected with proximity switch 2 of freezer body 1, one side fixedly connected with human response module 3 of freezer body 1, the inner wall fixedly connected with freezer baffle 4 of freezer body 1, one side outer wall fixedly connected with of freezer body 1 rotates seat 5, one side of rotating seat 5 is rotated and is connected with wind-up roll 6, one side that the seat 5 was rotated to wind-up roll 6 was kept away from is rotated and is connected with motor 7, the winding has transparent night curtain 8 on the wind-up roll 6, one side fixedly connected with night curtain base 9 of wind-up roll 6 is kept away from to transparent night curtain 8.

The output end signal of the human body induction module 3 is connected with a control panel, wherein the running interval time of the motor 7 is controlled to be 100 seconds through the control panel, the output end of the control panel is connected with the input end signal of the motor 7, and the output end of the proximity switch 2 is connected with the input end signal of the control panel.

Specifically, when human response module 3 sensed the human body and was close, with the convenient transmission of received signal to control panel department, control panel made things convenient for opening of control motor 7 to play the effect that transparent night curtain 8 was opened and is closed automatically, proximity switch 2 receives the contact back of night curtain base 9, and proximity switch 2 is with signal transmission to control panel, through control panel control motor 7 stall, thereby plays the effect of closed freezer body 1.

The position of the night shade base 9 corresponds up and down to the position of the proximity switch 2.

Specifically, when the night curtain base 9 moves downward, the night curtain base is convenient to gradually contact with the top of the proximity switch 2, so that the proximity switch 2 is opened, and the motor 7 is convenient to control to stop moving.

Motor 7 and one side fixed connection of freezer body 1, and set up the recess with motor 7 looks adaptation on the freezer body 1.

Specifically, the motor 7 is conveniently fixed and can be operated more stably.

The working principle is as follows:

when the refrigerator is used, firstly, when the human body induction module 3 induces that a human body approaches the refrigerator body 1, the motor 7 is controlled to start to rotate reversely through the control panel by transmitting a signal to the control panel, the motor 7 drives the winding roller 6 to rotate when rotating reversely, and then the transparent night curtain 8 is wound along with the motor and is gradually opened, so that the vegetables and food in the refrigerator can be conveniently taken by people;

when the person leaves, the motor 7 starts to rotate forwards after 100 seconds according to the design time of the control panel, the wind-up roller 6 is driven to rotate forwards, and the transparent night curtain 8 falls down gradually;

at the in-process that transparent night curtain 8 fell, when its night curtain base 9 contacted proximity switch 2 gradually, proximity switch 2 was with signal transmission to control panel, through control panel control motor 7 stall to play the effect of closed freezer body 1, can control the fresh-keeping temperature of freezer body 1 well, reduce the energy consumption of freezer body 1.
