Abstract
The utility model discloses a light-touch automatic door opener for refrigerators, comprising a control circuit, a power supply, a refrigerator cabinet, a refrigerator door, a driving device, an anti-thrust baffle plate, a refrigerator handle, etc. As a door opening stop switch arranged between the refrigerator cabinet and the refrigerator door and a light-touch switch arranged on the refrigerators are used to control the driving device to push the anti-thrust baffle plate, when the user holds the handle, the functions that when the door is touched lightly, the door can automatically open, when the door is opened, the light-touch automatic door opener can stop automatically, when the door is closed, the door can reset automatically are realized. The utility model has the advantages of safety, high sensitivity, simple circuit, and reasonable structure; the refrigerator is add with a unique function.
Description
The utility model relates to a kind of door opener, the automatic door opener of particularly a kind of soft-touch type refrigerator.
Now the refrigerator of producing and selling does not all have the self-opening door device, thus very hard when opening, and because firmly pulling can make refrigerator produce and rock, sealing system can not be done finely for this reason.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and a kind of automatic door opener of soft-touch type refrigerator that refrigerator is opened the door automatically is provided.
The purpose of this utility model can reach by following measure: the utility model comprises power supply, refrigerator body, chamber door, refrigerator handle; it is characterized in that: also have control circuit, transmission mechanism, thrust baffle, motor; transmission mechanism is loaded on the chamber door; thrust baffle is contained on the refrigerator body; the halt switch that opens the door is loaded between refrigerator body and the chamber door, and touch-switch is installed on the refrigerator handle.
The purpose of this utility model can also reach by following measure: transmission mechanism comprises crank rod assembly, halt switch, support, spacing and support connection pin; crank rod assembly is loaded on the support; and it is spacing to connect pin by spacing and support; one end can push up thrust baffle during its motion, and the other end can push up halt switch.Grid with controllable silicon SCR after touch-switch is connected with open the door halt switch and resistance R 1 joins, and the grid with controllable silicon SCR after halt switch is connected with resistance R 2 joins.
Fig. 1 is an electrical schematic diagram of the present utility model;
Fig. 2 is the structural representation of the utility model transmission mechanism;
Fig. 3 is the A-A cutaway view of the utility model transmission mechanism;
Fig. 4 is the assembling schematic diagram of the utility model on refrigerator.
The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):
With reference to Fig. 1～Fig. 4, the utility model is made up of control circuit 1, transmission mechanism 2, thrust baffle 3, power supply 4, refrigerator body 5, chamber door 6, refrigerator handle 7, motor 8, the halt switch 9 that opens the door, touch-switch 10 etc.Transmission mechanism 2 is loaded on the chamber door 6, and thrust baffle 3 is contained on the refrigerator body 5, so that the crank rod assembly in the transmission mechanism 2 is opened chamber door 6 by withstanding thrust baffle 3 when operation; The halt switch 9 that opens the door is loaded between refrigerator body 5 and the chamber door 6, and touch-switch 10 is installed on the refrigerator handle 7.Transmission mechanism 2 comprises crank rod assembly 11, halt switch 12, support 13, spacing and support connection pin 14; crank rod assembly 11 is loaded on the support 13; and it is spacing to connect pin 14 by spacing and support, and one end can push up thrust baffle 3 during its motion, and the other end can push up halt switch 12.
Among Fig. 1,8 is motor; SCR is a bidirectional triode thyristor; R1, R2 are two step-down current-limiting resistances; 10 is the touch-switch on the refrigerator handle 7; 9 are the halt switch that opens the door on the refrigerator body 5; 12 is that motor is from circling the automatic control halt switch.When refrigerator doors 6 was being closed, touch-switch 10 was in " opening " state, and the halt switch 9 that opens the door is in " closure " state, and halt switch 12 is in " opening " state.In the time of need opening the door, catch handle 7, make touch-switch 10 closures with hand, the controllable silicon SCR triggering and conducting, motor 8 gets electric work running, drives crank rod assembly 11, withstands thrust baffle 3, backs down chamber door 6 automatically.The halt switch 9 that opens the door this moment is opened gradually, cuts off the triggering of touch-switch 10.Halt switch 12 closure of upspringing in addition simultaneously, control SCR continues conducting, and motor 8 remains in operation.After crank rod assembly 11 rotates a circle, arrive original position again, contact halt switch 12, make it be pressed into disconnection, motor shutdown work.Close and recover SBR behind the door, wait for for the second time and triggering.
The utility model has following advantage compared to existing technology:
1. refrigerator doors is opened automatically, avoided refrigerator to produce and rocked, for refrigerator has increased unique function.
2. circuit is simple, and is rational in infrastructure, safe and reliable, highly sensitive, and volume is little, and cost is low, can satisfy refrigerator producer and user's demand.
