In this embodiment, the pressure adjusting unit is used for adjusting the pressure of the refrigerator liner, and the pressure adjusting unit of this embodiment will be described in detail.

The pressure regulating assembly of the present embodiment includes a pipe 101, a coil 102, and a magnetic member 103, as shown in fig. 4 and 5. Preferably, the pipe 101 is of a hollow structure, the coil 102 is wound on the pipe 101, the magnetic member 103 is slidably disposed in the pipe 101 and divides the pipe 101 into a first air storage portion 1011 and a second air storage portion 1012, the first air storage portion 1011 is communicated with the chamber to be regulated, the second air storage portion 1012 is communicated with the outside, and the coil 102 is further connected with the power supply device, and the magnetic member 103 moves in the pipe 101 and regulates the volumes of the first air storage portion 1011 and the second air storage portion 1012 based on the size and/or direction of the power supply of the coil 102, as shown in fig. 1, 2, 4 and 5. More preferably, the magnetic member 103 is a rubidium magnet, but not limited thereto, and the magnetic member 103 may be made of other magnetic materials. More preferably, the coil 102 is connected with a main control board of the refrigerator, and the main control board of the refrigerator provides current for the coil 102, and meanwhile, the main control board can also control the magnitude and direction of the current flowing through the coil 102.

The pressure adjusting assembly of the embodiment comprises a pipeline 101, a coil 102 and a magnetic part 103, wherein the pipeline 101 is of an internal hollow structure, the coil 102 is wound on the pipeline 101, the magnetic part 103 is slidably arranged in the pipeline 101 and divides the pipeline 101 into a first air storage part 1011 and a second air storage part 1012, the first air storage part 1011 is communicated with a cavity to be adjusted, the second air storage part 1012 is communicated with the outside, the coil 102 is further connected with a power supply device, the magnetic part 103 moves in the pipeline 101 and adjusts the volumes of the first air storage part 1011 and the second air storage part 1012 based on the size and/or direction of the current of the coil 102, and therefore, the pressure adjusting assembly of the embodiment can provide power for the magnetic part 103 through the current of the coil 102, so that the magnetic part 103 moves up and down in the pipeline 101, the volumes of the first air storage part 1011 and the second air storage part 1012 are adjusted, and the pressure in the cavity to be adjusted can be increased or decreased.

When the pressure regulating assembly of the embodiment is used for a refrigerator, before a user opens a door, the magnetic piece 103 is moved upwards, so that the volume of the first air storage part 1011 can be reduced, part of air in the first air storage part 1011 is extruded into the refrigerator liner, the pressure in the liner can be increased, the pressure in the liner is enabled to be consistent with the external atmospheric pressure, and the user can easily open the refrigerator door. On the other hand, compared with the structure that an open channel is arranged in the inner container foam in the prior art, the pressure regulating component of the embodiment can separate the inner container from the outside through the separation function of the magnetic piece 103, so that the problems of cold air leakage and condensation can be avoided, the refrigerating effect of the refrigerator can be improved, the energy consumption of the refrigerator can be reduced, and the use experience of a user can be improved. Namely, the pressure regulating component solves the technical problems that in the prior art, the pressure in the liner is enabled to be consistent with the external atmospheric pressure through an open channel, and cold air leakage and condensation exist.

According to a preferred embodiment, the shape of the magnetic element 103 matches the shape of the pipe 101, and the cross-sectional area of the magnetic element 103 is the same as the cross-sectional area of the pipe 101, as shown in fig. 5 and 6. Preferably, the magnetic member 103 is cylindrical. The height of the magnetic member 103 may not be limited. According to the pressure adjusting assembly of the preferred technical scheme of the embodiment, the cross-sectional area of the magnetic piece 103 is the same as that of the pipeline 101, so that the first air storage portion 1011 and the second air storage portion 1012 can be completely separated through the magnetic piece 103, and the problems that the first air storage portion 1011 and the second air storage portion 1012 at the upper end and the lower end of the magnetic piece 103 are ventilated with each other, the refrigerating effect and the energy consumption of a refrigerator are affected due to leakage of cold air, and the user experience is affected due to condensation are avoided.

According to a preferred embodiment, when the magnetic member 103 moves in a direction approaching the chamber to be regulated, the volume of the first air storage portion 1011 decreases and the pressure inside the chamber to be regulated increases; when the magnetic member 103 moves in a direction away from the chamber to be regulated, the volume of the first air storage portion 1011 increases and the pressure in the chamber to be regulated decreases. In the pressure regulating assembly according to the preferred technical solution of the present embodiment, when the volume of the pipe 101 is fixed, when the magnetic member 103 moves in a direction approaching to the chamber to be regulated, the volume of the first air storage portion 1011 is reduced, so that part of the air in the first air storage portion 1011 is extruded into the inner container of the refrigerator, and the pressure in the inner container can be increased, so that the pressure in the inner container is consistent with the external atmospheric pressure, and the user can easily open the refrigerator door; meanwhile, the volume of the second gas storage part 1012 increases, and since the second gas storage part 1012 is communicated with the outside, the outside gas can enter the second gas storage part 1012, so that the pressure in the second gas storage part 1012 is consistent with the outside atmospheric pressure. Similarly, when the magnetic member 103 moves in a direction away from the chamber to be regulated, the volume of the first air storage portion 1011 increases, so that part of the air in the refrigerator liner enters the first air storage portion 1011, thereby reducing the pressure in the liner, keeping the liner in a low-pressure state (specifically, lower than the atmospheric pressure), and improving the fresh-keeping effect of the refrigerator.

According to a preferred embodiment, when the coil 102 is energized to generate a magnetic field, the magnetic induction b= uNI/L, the magnetic member 103 is moved within the pipe 101 by controlling the direction of the current in the coil 102 to change the direction of the magnetic field, where N is the total number of turns of the coil 102, L is the length of the coil 102, u is a constant, and I is the magnitude of the current in the coil 102. As can be seen from fig. 1, the pressure regulating assembly is vertically mounted on the back plate of the refrigerator, and according to the right-hand screw rule (i.e., ampere rule), when the coil 102 is energized, the N pole of the magnetic field generated by the coil 102 is directed either upward or downward, so that the magnetic member 103 needs to be vertically placed in the energized coil so that the N pole of the magnetic member 103 is also upward or downward. Referring to fig. 8, the right hand holds the coil so that the four fingers point in the current direction, the direction in which the thumb points is the magnetic field direction (N pole). It can be seen that the energized coil 102 can generate a magnetic field (electromagnetic), where the magnetic induction b= uNI/L, N is the total number of turns of the coil 102, L is the length of the coil 102, u is a constant, and I is the magnitude of the current in the coil 102. It can be seen that the direction of the magnetic field is related to the direction of the current, changing the direction of the current and the magnetic field changes accordingly.

Exemplary: assuming that the coil 102 is wound in the manner shown in fig. 8 and the current direction is the four-finger direction as curled in fig. 8, the N pole of the magnetic field generated by the coil 102 after energization is directed upward. Assuming that the magnetic pole direction of the magnetic member 103 is as shown in fig. 8, the upper is an S pole and the lower is an N pole, the magnetic member 103 moves upward according to the "opposite attraction, like repulsion". Conversely, by controlling the current in the opposite direction to that shown in fig. 8, the S-pole of the magnetic field generated by the energized coil 102 is directed upward. Assuming that the magnetic pole direction of the magnetic member 103 is as shown in fig. 8, the upper is an S pole and the lower is an N pole, the magnetic member 103 moves downward according to the "opposite attraction, like repulsion".

Of course, the winding manner of the coil 102 may be opposite to that shown in fig. 8, and the current direction may be opposite to that shown in fig. 8, but the analysis process is identical to that described above, and will not be repeated here.

It will be appreciated that when the coil 102 is energized, the coil is caused to generate a magnetic field, which is changed by controlling the direction of the current. The generated magnetic field can generate thrust or attraction force to the magnetic piece 103 according to the 'opposite attraction and the like repulsion', so that the motion track of the magnetic piece 103 is changed.

Assuming that the refrigeration device is a refrigerator, in specific practice, the power supply device can be a main control board of the refrigerator, the coil 102 is connected with the main control board of the refrigerator, current is provided for the coil 102 through the main control board of the refrigerator, and meanwhile, the magnitude and the direction of the current flowing through the coil 102 can be controlled through the main control board. Before a user opens the door, the main control board energizes the coil 102 to enable the magnetic piece 103 to move upwards, so that the volume of the first air storage part 1011 can be reduced, part of air in the first air storage part 1011 is extruded into the refrigerator cavity, so that the pressure in the cavity can be increased, the pressure in the cavity is enabled to be consistent with the external atmospheric pressure, and the user can easily open the refrigerator door.

According to a preferred embodiment, the magnetic member 103 is moved away from the chamber to be regulated when the direction of the current in the coil 102 is such that the direction of the magnetic force exerted by the magnetic member 103 is the same as the direction of gravity. When the direction of the magnetic force applied to the magnetic element 103 is the same as the direction of gravity in the coil 102, the force (sum of magnetic force and gravity) applied to the magnetic element 103 is downward no matter the magnitude of the current, so that the magnetic element 103 can be driven to move downward, i.e. the magnetic element 103 moves in a direction away from the cavity to be regulated, so that the pressure in the liner can be reduced, and the fresh-keeping effect of the refrigerator can be improved.

According to a preferred embodiment, the magnetic element 103 is moved away from the chamber to be regulated when the circulating current in the coil 102 is 0. In the pressure adjusting assembly according to the preferred technical solution of the present embodiment, when the current flowing in the coil 102 is 0, the magnetic member 103 is only under the action of gravity, and under the action of gravity, the magnetic member 103 moves downward, i.e. the magnetic member 103 moves in a direction away from the chamber to be adjusted, so as to reduce the pressure in the inner container and improve the fresh-keeping effect of the refrigerator.

According to a preferred embodiment, the pressure regulating assembly further comprises a first fixing member 104, the first fixing member 104 being disposed under the magnetic member 103, and the first fixing member 104 being further disposed at the corner of the pipe 101 such that the cross-sectional area of the corner of the pipe 101 is smaller than the cross-sectional area of the magnetic member 103, as shown in fig. 6. Preferably, the first fixing member 104 is a fixing pin, and the fixing pin is transversely disposed at a corner of the pipe 101. According to the pressure adjusting assembly of the preferred technical scheme of the embodiment, the magnetic piece 103 can be prevented from falling to the corner of the pipeline 101 through the blocking effect of the first fixing piece 104, so that the problem that the magnetic piece 103 cannot move upwards due to clamping is solved, and the reliability of the upward and downward movement of the magnetic piece 103 in the pipeline 101 is ensured.

According to a preferred embodiment, the pressure regulating assembly further comprises a second fixing member 105, the second fixing member 105 being fixedly connected to the portion to be installed, and the pipe 101 being fixedly connected to the second fixing member 105, as shown in fig. 1 and 3. Preferably, the second fixing member 105 has a through hole 1051 therein, the pipe 101 is mounted in the through hole 1051, and the through hole 1051 is interference-fitted with the pipe 101, as shown in fig. 7. Preferably, the portion to be mounted is, for example, a lower bottom plate 201 of a refrigerator. More preferably, the second fixing member 105 is disposed below the lower plate 201, and the lower plate 201 is also provided with a through hole for mounting the power pipeline 101. According to the pressure adjusting assembly of the preferred technical scheme of the embodiment, the pipeline 101 is fixed at the position of the portion to be installed through the second fixing piece 105, so that the fixing of the pipeline 101 can be achieved, the influence on the strength of the position of the portion to be installed can be avoided, and the reliability of the refrigerator is guaranteed.
