DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] The following specific examples illustrate the embodiments of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model.
[0021] As Figures 1 - 2 shown, an opening door delay alarm is set in the gap between the top of the door and the upper instrument box (the corresponding position is close to the direction of the door handle); through the actions of opening and closing the door, the information transmission generated by the pressing and separating of the contact button of the door control switch K1 is used to control the functions of the fan, the lighting lamp, and the alarm.
[0022] The opening door delay alarm includes a switch body 1, a door control switch K1 2 installed on the switch body 1, and a plug-in pin 3. The switch body plays the role of fixing and framing the overall functional housing. The door control switch K1 contacts the door body through opening and closing the door, and plays the role of opening and closing the internal contacts of the switch body; the plug-in pin 4 is a wiring terminal for connecting voltage, and plays the role of being energized and connected in common with the alarm and delay module;
[0023] A fixed buckle 4 is also installed on the switch body, which plays the role of installing or replacing the overall switch and connecting and fixing the product;
[0024] As Figure 3 shown, the electronic components of the opening door delay alarm are installed in the switch body, including a power supply providing unit, a driving output module, a timing module, and an alarm module. The power supply providing unit includes an intermediate relay 5, a main control board 6 connected to the intermediate relay, and a door control switch K1. When the door body is closed, the door body touches the door control switch K1, and the door control switch K1 forms a closed circuit.
[0025] The timing module includes a closing door delay timer and an opening door delay timer. The driving output module includes a lighting lamp 7 and a fan 8. The lighting lamp 7 is connected to the intermediate relay 5 and the closing door delay timer 9; the alarm module includes a buzzer and an alarm lamp 11. The buzzer 10 and the alarm lamp 11 are connected to the opening door delay timer 12; the circuit between the intermediate relay 5 and the closing door delay timer 9 is controlled by a switch K2, the circuit between the closing door delay timer 9 and the lighting lamp 7 is controlled by a switch K3, the circuit between the intermediate relay 5 and the fan 8 is controlled by a switch K4, and the circuit between the intermediate relay 5 and the opening door delay timer 12 is controlled by a switch K5; the circuit between the opening door delay timer 12 and the buzzer 10 and the alarm lamp 11 is controlled and connected by a switch K6.
[0026] When the door body is closed and the door body touches the door control switch K1, after the door control switch K1 forms a closed circuit, the switch K4 is turned on, the fan starts, and the intermediate relay is energized. After the switch K2 is closed, the closing door delay timer is started (the delay time can be set by oneself from 0 to 100S). When the closing door delay time arrives, the switch K3 is turned off to control the lighting duration of the lighting lamp;
[0027] Similarly, when opening the door, the door body is separated from the door control switch K1, and the door control switch K1 becomes an open circuit. At this time, the switch K4 is disconnected, and the fan is turned off. At the same time, the intermediate relay is energized to start the door opening delay timer (the delay time can be set by oneself from 0 to 100S) through the switch K5. After the door opening delay time arrives, the switch K6 is closed, thereby starting the buzzer and the alarm light.
[0028] The alarm is mainly indicated by the buzzer sound and the warning light, to prevent the loss of cold air inside the box caused by opening the door for a long time or not in place when closing, thus prompting the operator to check and reset.
[0029] When opening the door, the alarm light lights up instantly, and the door opening delay timer in the timing module starts to delay and count, to prevent the door from being opened for too long, resulting in the loss of cold air inside the box and giving an audible and visual alarm; when closing the door, the door closing delay timer in the timing module also starts to delay and count, and it goes out after (0 to 100S can be set) after closing the door, so as to effectively control the lighting duration inside the box to save energy and avoid waste.
[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the present technical solution, and they should all be covered within the scope of the claims of the present invention.
