Referring to fig. 1-7, the present invention provides a technical solution:
electromagnetic control infinitely variable speed switch door freezer, including the main cabinet body 1, the main cabinet body 1 includes cabinet body casing 11, sliding connection has two cabinet doors 2 in the top door mouth of cabinet body casing 11, all is equipped with electro-magnet group 3 in the lateral wall around the cabinet mouth of cabinet body casing 11, and electro-magnet group 3 includes a plurality of electro-magnet 31, presss from both sides between two adjacent electro-magnet 31 and is equipped with electrical insulation plywood 32, all inlays in the lateral wall of both sides around cabinet door 2 and is equipped with armature 4, still has laid singlechip control circuit board 5 in the main cabinet body 1.
In this embodiment, the lower end of the outer wall of one side of the cabinet body 11 is provided with an equipment box cover 12, wherein the equipment box cover 12 is provided with an equipment box inside for installing equipment such as a refrigerator and a motor of a refrigerator.
Further, a heat dissipation opening 121 is formed in the middle of the equipment box cover 12 and used for heat dissipation of the refrigerator.
In this embodiment, two cabinet doors 2 are crisscross from top to bottom, and two cabinet doors 2 are the butt of sliding relatively, and are the same with conventional freezer structural design.
Further, the cabinet door 2 comprises an outer frame 21, and a handle 211 is integrally formed at one end of the outer frame 21 away from the other cabinet door 2, so that manual door opening and closing operations can be conveniently performed through the handle 211.
Furthermore, a glass plate 22 is fixedly embedded in the outer frame 21, and the condition inside the refrigerator can be directly viewed from the outside through the glass plate 22.
In this embodiment, the electromagnet 31 includes an iron core 311, and a coil 312 is wound outside the iron core 311, so that the electromagnet 31 generates magnetism when the coil 312 is energized, thereby attracting the armature 4.
Further, the armature 4 is fixedly embedded in the side wall of the outer frame 21, so that the armature 4 is firm and stable, and the electromagnet 31 is convenient to attract the armature 4 to drive the cabinet door 2 to move.
Further, when the cabinet door 2 is installed in the cabinet opening of the main cabinet 1, the armature 4 corresponds to the horizontal position of the electromagnet group 3 corresponding to the position thereof, and the armature 4 abuts against the iron core 311 corresponding to the position thereof.
Specifically, during the sliding opening of the cabinet door 2, the armature 4 moves along the distribution direction of the electromagnets 31 in the electromagnet group 3.
Specifically, the length of the armature 4 is greater than that of the iron core 311, so that after the armature 4 is attracted to a specified position by one of the electromagnets 31, the front end and the rear end of the armature 4 extend to the electromagnets 31 at adjacent positions respectively, and after the electromagnets 31 at adjacent positions are electrified to generate magnetism, the armature 4 can be attracted sensitively, so that the armature 4 can react quickly and move in the direction of the position of the electrified electromagnet 31.
In this embodiment, the single chip microcomputer control circuit board 5 is installed inside the equipment box cover 12, so that the single chip microcomputer control circuit board 5 can be connected with the original circuit board/circuit of the refrigerator.
Specifically, the coil 312 is connected to the controller via a power line, and the controller is in signal connection with the single chip microcomputer control circuit board 5 via a signal line, so that the single chip microcomputer control circuit board 5 can sequentially control the power on-off process of each electromagnet 31 via the controller.
The electromagnets 31 are sequentially numbered towards the middle from the position close to the edge of the cabinet opening, the power-on and power-off operations are sequentially performed according to the number sequence of the electromagnets 31 when the cabinet door 2 is opened, and the power-on and power-off operations are sequentially performed according to the reverse sequence of the numbers when the cabinet door 2 is closed.
Specifically, the working principle that the electromagnet group 3 and the armature iron 4 are matched to realize the opening and closing process of the cabinet door 2 is as follows:
the first electromagnet 31 generates magnetism after being electrified, the electromagnet 31 with magnetism can attract the nearby armature 4, the armature 4 is installed together with the cabinet door 2, and the cabinet door 2 moves towards the electrified electromagnet 31 along with the armature 4; when the cabinet door 2 moves to a proper position, the first electromagnet 31 is powered off and the second electromagnet 31 is powered on, and under the inertia effect of forward movement of the cabinet door 2, the second electromagnet 31 can continuously attract the armature 4 in the cabinet door 2, so that the cabinet door 2 is driven to continuously move forward, and so on until the electromagnet at the tail end and the armature 4 are attracted by the electromagnet 3; when the door is closed, the energization sequence of the electromagnet 31 is reversed until completely closed.
The power-on and power-off time of each electromagnet 31 is adjusted by the singlechip control circuit board 5; the singlechip control circuit board 5 can also receive signals from the opening and closing of the door, so as to adjust the electrifying sequence of each electromagnet 31.
In addition, the on-off time of the electromagnet 31 is controlled by the singlechip control circuit board 5, the shorter the on-off time is, the faster the operation speed of the cabinet door 2 is, and stepless speed change can be realized;
the singlechip control circuit board 5 receives signals from the outside, and opens or closes the door, so that the door opening and closing direction is changed;
if the singlechip control circuit board 5 adopts a high-end singlechip, the door body switch at any position can be realized;
furthermore, if the single chip microcomputer control circuit board 5 can receive an external WIFI signal, the process of opening and closing the door by remote control can be realized.
It should be noted that the structure of the one-chip microcomputer control circuit board 5 and the programming process thereof are well known to those skilled in the art, and are not described herein again.
Furthermore, it is worth mentioning that the combination of the electromagnet group 3 and the armature 4 may be provided in one, two or four groups;
when only one group is arranged, the opening and closing of one of the cabinet doors 2 can be controlled only through one side, but the cabinet doors are likely to shift or move sluggishly in the opening and closing process; when two groups are arranged, the opening and closing of one of the cabinet doors 2 can be controlled simultaneously through two sides, so that the opening and closing are smoother, and the opening and closing of the two cabinet doors 2 can also be controlled respectively through one side; when four groups are arranged, the opening and closing of the two cabinet doors 2 can be respectively controlled through two sides, so that the two cabinet doors 2 can be smoothly and automatically opened and closed.
When the electromagnetic control stepless speed change door opening and closing refrigerator is used, the main cabinet body 1 is electrified to normally operate, when the cabinet door 2 needs to be opened, the singlechip control circuit board 5 controls the power supply of each electromagnet 31 to be switched on and off in sequence according to the serial number sequence through the controller, and the electrified electromagnet 31 attracts the armature iron 4 to drive the cabinet door 2 to move, so that the cabinet door 2 moves along the direction of the electromagnet group 3 until the cabinet door 2 is completely opened; when the cabinet door 2 is closed, the circuit board 5 is controlled by the single chip microcomputer to control the power on-off of each electromagnet 31 according to the reverse numbering sequence through the controller until the cabinet door 2 is completely closed.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above-described invention, and the above-described invention and the description thereof are only preferred examples of the present invention and are not intended to limit the present invention, and various changes and modifications may be made within the scope of the claimed invention without departing from the spirit and scope of the present invention.
