The invention provides a preferable embodiment and discloses a refrigerator, in particular to a horizontal refrigerator. As shown in fig. 1 to 3, the refrigerator includes a cabinet 10, and a first door 12 and a second door 14 both slidably opening or closing the cabinet 10, when the first door 12 and the second door 14 are both in a closed state, the first door 12 and the second door 14 are partially overlapped at a middle position of the cabinet 10, a first magnetic sheet 16 is disposed on the first door 12 at the partially overlapped position of the middle position, a thickness of the first magnetic sheet 16 gradually decreases from the partially overlapped position of the middle position to a direction away from the middle position, a mother magnetic sheet 18 and a magnetic sensor 20 are disposed on the cabinet 10, and positions of the mother magnetic sheet 18 and the magnetic sensor 20 correspond to positions of the first magnetic sheet 16. Preferably, the mother magnetic sheet 18 and the magnetic sensor element 20 are integrally packaged to form an integral package 21. Of course, the mother magnetic sheet 18 and the magnetic sensor element 20 may be provided separately. In addition, the thickness of the female magnet pieces 18 is uniform in the sliding direction of the first door body 12.

The refrigerator further comprises a main control unit 22, the mother magnetic sheet 18 and the magnetic sensor 20 are electrically connected with the main control unit 22, and the main control unit 22 judges the opening or closing of the first door body 12 and the opening size of the first door body 12 according to the electric signal converted from the sensing signal of the magnetic sensor 20. When the first door body 12 is closed, the thickness of the superposition of the mother magnetic sheet 18 and the first magnetic sheet 16 is the largest, the generated magnetic force is the largest, the electric signal converted by the induction signal of the energized magnetic sensor 20 is the largest, and the main control unit 22 confirms that the first door body 12 is closed according to the acquired electric signal parameters. When the first door body 12 is opened, the superposed thickness of the mother magnet piece 18 and the first magnet piece 16 becomes thinner, the magnetic force is reduced, the thickness of the first magnet piece 16 gradually changes, so that the electric signals correspond to different thickness values to confirm the opening position of the first door body 12, and the electric signals converted by the induction signals of the magnetic sensor 20 are sequentially reduced along with the increase of the opening degree of the first door body 12, so that the opening degree of the first door body 12 is judged. Therefore, the invention can reliably and effectively judge the opening or closing state of the first door body 12 and the opening degree of the first door body. Of course, other methods may be used to determine the opening or closing of the first door 12 and the opening of the first door 12.

In the present embodiment, the magnetic sensor element 20 is provided as a coil 20. Of course, the magnetic sensor element 20 can be provided as other magnetic sensors, for example, the magnetic sensor element 20 can be provided as a semiconductor magnetic sensor. Specifically, the main control unit 22 determines the opening or closing of the first door 12 and the opening of the first door 12 according to the electromotive force induced at the two ends of the magnetic sensor 20. When the first door body 12 is closed, the thickness of the superposition of the mother magnetic sheet 18 and the first magnetic sheet 16 is the largest, the generated magnetic force is the largest, the induced electromotive force generated at the two ends of the energized coil 20 is the largest, and the main control unit 22 confirms that the first door body 12 is closed according to the acquired induced electromotive force parameters. When the first door body 12 is opened, the superposed thickness of the mother magnet piece 18 and the first magnet piece 16 becomes thinner, the magnetic force is reduced, the opening position of the first door body 12 is confirmed by corresponding different thickness values of the induced electromotive force through the gradual change of the thickness of the first magnet piece 16, and the generated induced electromotive force is reduced in sequence along with the increase of the opening degree of the first door body 12, so that the opening degree of the first door body 12 is judged.

The cooler also includes a refrigeration module 24 electrically connected to the master control unit 22. The main control unit 22 determines the opening or closing of the first door 12 and the opening of the first door 12, and the main control unit 22 controls the refrigeration module 24 to adjust the refrigeration intensity according to the opening of the first door 12. When the opening of the first door body 12 is large, the refrigeration intensity is reduced, and when the opening of the first door body 12 is small, the refrigeration intensity is increased, so that the temperature in the refrigerator is effectively adjusted according to the state of the first door body 12, the refrigerator is more energy-saving, and the use cost is lower.

Specifically, the thickness of the first magnet piece 16 gradually decreases in a gradient from the overlapping portion of the intermediate position toward a direction away from the intermediate position. Of course, the thickness of the first magnetic sheet 16 may be gradually reduced from the overlapping portion of the middle position to a direction away from the middle position.

Further, the first magnetic sheet 16 has a first bottom plane 26 and a first top inclined plane 28 forming an acute angle with the first bottom plane 26, and the first bottom plane 26 faces the mother magnetic sheet 18 and is parallel to the sliding direction of the first door body 12. In addition, the first magnetic sheet 16 has a first end face 30 connecting the first bottom plane 26 and the first top inclined plane 28, and in the preferred embodiment, the first end face 30 is substantially perpendicular to the first bottom plane 26.

In addition, as the first door body 12 is gradually opened, the stacked thickness of the first magnetic sheet 16 and the mother magnetic sheet 18 gradually becomes thinner, the induced electromotive force generated by the magnetic sensor 20 gradually decreases, and a plurality of different induced electromotive force values corresponding to different opening degrees of the first door body 12 are defined.

The main control unit 22 further determines the opening or closing of the second door 14 and the opening of the second door 14, and the main control unit 22 controls the refrigeration module 24 to adjust the refrigeration intensity according to the opening of the second door 14. Therefore, the temperature in the refrigerator is effectively adjusted according to the state of the second door body 14, and energy-saving control is realized.

In the preferred embodiment, the second magnet piece 32 is also provided on the second door body 14 at the overlapping part of the middle position, the thickness of the second magnet piece 32 gradually decreases from the overlapping part of the middle position to the direction away from the middle position, and the position of the second magnet piece 32 corresponds to the positions of the mother magnet piece 18 and the magnetic sensor element 20. The second pole piece 32 is similar in structure to the first pole piece 16, and specifically, the thickness of the second pole piece 32 gradually decreases from the partially overlapped position of the middle position to a direction away from the middle position. When the first door body 12 is required to be opened normally, the first door body 12 is slid to the position corresponding to the position of the second door body 14, and when the second door body 14 is required to be opened, the second door body 14 is slid to the position corresponding to the position of the first door body 12, so that the gradual change directions of the first magnetic sheet 16 and the second magnetic sheet 32 are opposite.

Similar to the judgment of the first door body 12, when the second door body 14 is closed, the thickness of the superposition of the mother magnetic sheet 18 and the second magnetic sheet 32 is the largest, the generated magnetic force is the largest, the induced electromotive force generated at the two ends of the energized magnetic sensor 20 is the largest, and the main control unit 22 confirms that the second door body 14 is closed according to the obtained induced electromotive force parameters. When the second door body 14 is opened, the superposed thickness of the mother magnet piece 18 and the second magnet piece 32 becomes thinner, the magnetic force is reduced, the opening position of the second door body 14 is confirmed by corresponding different thickness values of the induced electromotive force through the gradual change of the thickness of the second magnet piece 32, and the generated induced electromotive force is reduced in sequence along with the increase of the opening degree of the second door body 14, so that the opening degree of the second door body 14 is judged. Of course, other methods may be used to determine the opening or closing of the second door 14 and the opening of the second door 14.

Similarly, the second magnetic sheet 32 has a second bottom plane 34 and a second top inclined plane 36 forming an acute angle with the second bottom plane 34, and the second bottom plane 34 faces the female magnetic sheet 18 and is parallel to the sliding direction of the second door 14. In addition, the second magnetic sheet 32 has a second end surface 38 connecting the second bottom plane 34 and the second top inclined plane 36, and in the preferred embodiment, the second end surface 38 is substantially perpendicular to the second bottom plane 34.

Further, the refrigerator also comprises a timing module 40 for judging the door opening time of the first door body 12, the timing module 40 is electrically connected with the main control unit 22, and the main control unit 22 controls the refrigeration module 24 according to the door opening size and the door opening time of the first door body 12. When the opening degree of the first door body 12 or the second door body 14 is large and the door opening time is long, the refrigerating intensity of the refrigerating module 24 is reduced. When the opening degree of the first door body 12 or the second door body 14 is small and the door opening time is short, the refrigerating intensity of the refrigerating module 24 is increased.

The refrigeration module 24 comprises a compressor and an expansion valve, and the operation time of the compressor is adjusted and/or the opening degree of the expansion valve is adjusted according to the opening degree of the first door body 12. Similarly, the operation time of the compressor and/or the opening degree of the expansion valve can be adjusted according to the opening degree of the second door body 14. Specifically, when the opening degree of the first door 12 or the second door 14 is large and the door opening time is long, the operation time of the compressor is reduced to reduce the refrigeration intensity, and/or the opening degree of the expansion valve is reduced to reduce the refrigeration intensity of the refrigeration module 24, so that energy saving is achieved. When the opening degree of the first door body 12 or the second door body 14 is small and the door opening time is short, the refrigerating intensity is increased by prolonging the operation time of the compressor and/or the refrigerating intensity of the refrigerating module 24 is increased by increasing the opening degree of the expansion valve.

The refrigerator further comprises an alarm module 42 electrically connected with the main control unit 22, and when the door opening time of the first door body 12 is longer than a first preset time, the alarm module 42 gives an alarm. In addition, when the door opening time of the second door body 14 is greater than the second preset time, the alarm module 42 also gives an alarm. The first preset time and the second preset time may be equal or unequal.

The above-listed detailed description is only a specific description of a possible embodiment of the present invention, and they are not intended to limit the scope of the present invention, and equivalent embodiments or modifications made without departing from the technical spirit of the present invention should be included in the scope of the present invention.
