Abstract
The utility model relates to an electric air door, particularly to an electric air door which has a position feed back signal and is used in an air cooling refrigerator, and a refrigerator with the electric air door. The refrigerator comprises the electric air door and a CPU. The electric air door comprises an air door and an air door frame; the air door is installed on the air door frame via an air door shaft; a motor is arranged at one end of the air door shaft for controlling the open/close of the air door by controlling the air door shaft; the motor is connected with the CPU; a rotary potentiometer is arranged at the other end of the air door shaft for reflecting the opening of the air door; and the rotary potentiometer is connected with the CPU to transmit the opening information of the air door to the CPU. The electric air door and the refrigerator with the electric air door provided by the utility model can transmit the position feed back signal reflecting the opening of the air door to the CPU at any time, so that the CPU can perform fine adjustment of the temperature in a refrigerating chamber by accurately adjusting the opening of the air door.
Description
Technical field
The utility model technology relates to a kind of MOD, specifically, relates to the MOD that a kind of wind cooling refrigerator is used.
Background technology
Wind cooling refrigerator of the prior art all adopts MOD mostly, but MOD of the prior art generally can not be sent to CPU with the position feed back signal of the aperture of air door, so the control system of refrigerator can't be known the aperture of air door, in the time need finely tuning, just can't realize like this by the aperture of adjusting air door to the temperature of refrigerating chamber or refrigerating chamber.
Summary of the invention
Technical purpose of the present utility model is to overcome above defective, and the MOD of band position feed back signal is provided, and has the refrigerator of this MOD.
The technical scheme of MOD of the present utility model is such: it comprises air door, air door, air door is installed on the air door by axle of the air door, one end of axle of the air door is provided with the switching of motor by control axle of the air door control air door, the other end of axle of the air door is provided with the aperture that rotational potentiometer reflects air door, and the junction of the two ends of axle of the air door and motor and rotational potentiometer is provided with the air door bearing.
The technical scheme that is provided with the refrigerator of MOD of the present utility model is such: it comprises MOD, CPU, MOD comprises air door, air door, air door is installed on the air door by axle of the air door, one end of axle of the air door is provided with the switching of motor by control axle of the air door control air door, motor is connected with CPU, the other end of axle of the air door is provided with the aperture that rotational potentiometer reflects air door, the opening information that rotational potentiometer is connected air door with CPU is transferred to CPU, and the junction of the two ends of axle of the air door and motor and rotational potentiometer is provided with the air door bearing.
MOD of the present utility model and have the refrigerator of this MOD can be at any time be transferred to CPU with the position feed back signal of the aperture of air door, and CPU just can come the temperature of refrigerating chamber is finely tuned by the aperture of accurate adjustment air door.
Description of drawings
Fig. 1 is the disassemblying structure schematic diagram of MOD of the present utility model;
Fig. 2 is a refrigerator structure block diagram of the present utility model.
The specific embodiment
It comprises MOD, CPU the refrigerator that MOD is set of the present utility model, MOD comprises air door 3, air door 2, air door 3 is installed on the air door 2 by axle of the air door 6 and mounting bracket 1, one end of axle of the air door 6 is provided with the switching of motor 7 by control axle of the air door 6 control air doors 3, motor 7 is connected with CPU, the other end of axle of the air door 6 is provided with the aperture that rotational potentiometer 4 reflects air door 3, rotational potentiometer 4 is connected with CPU, the opening information of air door 3 is transferred to CPU, and the junction of the two ends of axle of the air door 6 and motor 7 and rotational potentiometer 4 is provided with air door bearing 5.
Refrigerator of the present utility model is in use because the axle of the air door 6 of MOD is provided with rotational potentiometer 4, and rotational potentiometer 4 is connected with CPU, so when air door 3 actions, rotational potentiometer 4 also rotates along with the rotation of axle of the air door 6, thereby its resistance generation respective change, it directly sends this variation to CPU, CPU just can obtain air door 3 position feed back signals through handling, thereby know the aperture of air door 3, when small variation took place the temperature of the refrigerating chamber of refrigerator, CPU just can finely tune the temperature of refrigerating chamber by the aperture of adjustment air door 3, realize the constant temperature of refrigerating chamber, be very beneficial for the fresh-keeping of food.
The MOD of the present utility model and refrigerator of this MOD is set, simple in structure, effectively improved the fresh keeping property of refrigerator, can extensive use in the refrigerator field.
