The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As mentioned above, in order to solve the problem that the vibration generated by the compressor, the cooling fan and other components of the refrigerator during the operation is transmitted to the ground to cause the noise of the refrigerator to be larger, the utility model provides a novel magnetic suspension refrigerator, the structure of which can be seen in fig. 1 and 2.

Referring to fig. 1, in an exemplary embodiment, a refrigerator 10 includes a refrigerator main body 11 and a magnetic base 13, and the refrigerator main body 11 is disposed opposite to the magnetic base 13. The refrigerator main body 11 is a combination of a cabinet and refrigerator components in the cabinet, wherein the refrigerator components in the cabinet include common refrigerator components such as a compressor, a freezing chamber, a fresh food compartment, and the like. The magnetic base 13 is used for placing the refrigerator main body 11, and when the refrigerator 10 is required to be used, the magnetic base 13 is placed on the ground, and the refrigerator main body 11 is placed on the magnetic base 13.

The first magnetic member 12 is mounted to the bottom of the refrigerator main body 11, and the first magnetic member 12 is fixedly mounted to the surface of the bottom of the refrigerator main body 11 by, for example, screws. Since the bottom of the refrigerator main body 11 is opposed to the magnetic base 13 having magnetism, the position between the first magnetic member 12 and the magnetic base 13 is also opposed. The magnetic pole polarity of the end of the first magnetic member 12 close to the magnetic base 13 is the same as the magnetic pole polarity of the end of the magnetic base 13 close to the first magnetic member 12, so that a repulsive force is generated between the first magnetic member 12 and the magnetic base 13 to make the refrigerator main body 11 float on the magnetic base 13.

Therefore, the refrigerator main body 11 and the magnetic base 13 are separated from each other by air, so that direct contact between the refrigerator main body 11 and the ground is blocked, when the refrigerator 10 is in a working state, vibration generated by the refrigerator main body 11 cannot be transmitted to the magnetic base 13, and the vibration cannot be transmitted to the ground and the ground to touch the ground to aggravate noise, so that the noise generated when the refrigerator 10 works can be weakened.

Specifically, the first magnetic member 12 may be an electromagnet or a permanent magnet or other magnetic component, and the magnetic base 13 may also be a magnetic component such as an electromagnet or a permanent magnet, which is not limited herein, but it is required to ensure that the polarity of the magnetic pole at the end of the first magnetic member 12 close to the magnetic base 13 is the same as the polarity of the magnetic pole at the end of the magnetic base 13 close to the first magnetic member 12, so as to generate a repulsive force between the first magnetic member 12 and the magnetic base 13, and the refrigerator main body 11 is suspended on the magnetic base 13 based on the repulsive force.

The magnetic base 13 may include a second magnetic member 131 and a support foot 132, the second magnetic member 131 being mounted above the support foot 132 to be close to the first magnetic member 12 to generate a large repulsive force with the first magnetic member 12. The supporting foot 132 may be a sheet metal part, so that the second magnetic member 131 can be adsorbed on the supporting foot 132, or the second magnetic member 131 may also be adsorbed on the supporting foot 132 by means of glue, which is not limited herein.

Support feet 132 are intended to be placed on the ground, so the bottom of support feet 132 should be flat. In order to increase the friction between the support foot 132 and the ground, an anti-slip member such as rubber may be disposed at the bottom of the support foot 132, or an anti-slip pattern may be disposed on the bottom surface of the support foot 132 to ensure the stability of the refrigerator 10.

In some embodiments, the first magnetic member 12 is an electromagnet and the second magnetic member 131 is a permanent magnet. The electromagnet is formed by winding a conductive winding matched with the power of the iron core outside the iron core, and the line image magnet with current has magnetism, and does not have magnetism when the coil is not electrified.

When the refrigerator 10 is not powered on, the first magnetic member 12 has no magnetism, and thus the first magnetic member 12 together with the refrigerator main body 11 can be directly placed on the magnetic base 13. When the refrigerator 10 is powered on, the first magnetic member 12 is correspondingly magnetic and mutually repulses with the second magnetic member 131, and the generated repulsion force enables the refrigerator main body 11 to be levitated relative to the magnetic base 13. Illustratively, when the refrigerator 10 is powered on, the current direction in the first magnetic member 12 is as shown in fig. 2, according to the spiral rule, the first magnetic member 12 generates two upper and lower magnetic poles, and the upper magnetic pole is an N pole, the lower magnetic pole is an S pole, and correspondingly, the upper magnetic pole of the second magnetic member 131 is an S pole, and the lower magnetic pole of the second magnetic member 131 is an N pole, so as to ensure that the magnetic poles at the ends close to each other between the first magnetic member 12 and the second magnetic member 131 have the same polarity, thereby generating the repulsive force. When the current direction in the first magnetic member 12 is opposite to the current direction shown in fig. 2, the magnetic pole polarity distribution of the first magnetic member 12 and the second magnetic member 131 is opposite, and will not be described herein.

Therefore, when the refrigerator 10 is not powered on, the refrigerator main body 11 can be directly placed on the magnetic base 13 without generating vibration because the refrigerator 10 is not operated. When the refrigerator 10 is powered on, the refrigerator main body 11 automatically floats on the magnetic base 13 under the action of the repulsive force between the first magnetic member 12 and the second magnetic member 131, so that the vibration generated by the refrigerator main body 11 is only aerial vibration, and the vibration is not transmitted to the ground to aggravate the noise generated by the vibration. That is, the refrigerator 10 does not emit a large noise in any state, so that the refrigerator 10 has a high user experience.

In some embodiments, since the weights of the refrigerators of different brands or different models are different, in order to ensure that the levitation force between the first magnetic member 12 and the second magnetic member 131 can levitate the refrigerator main body 11, the magnitude of the levitation force between the first magnetic member 12 and the second magnetic member 131 may be set according to the weight of the refrigerator. For example, the refrigerators with different weights may use electromagnets with different numbers of coils as the first magnetic member 12, and based on the different numbers of coils, the first magnetic member 12 has different magnetic properties, for example, the electromagnet with the larger number of coils has larger magnetic properties, so that the levitation force between the first magnetic member 12 and the second magnetic member 131 is larger, so that the levitation force between the first magnetic member 12 and the second magnetic member 131 is different.

As also shown in fig. 1, in some embodiments, the first magnetic members 12 are respectively installed at each bottom corner of the bottom of the refrigerator main body 11, and thus the number of the first magnetic members 12 is at least 4. The first magnetic member 12 may also be mounted at other positions on the bottom of the refrigerator main body 11, for example, on respective sides of the bottom of the refrigerator main body 11. The number of the magnetic bases 13 is the same as that of the first magnetic members 12, so as to ensure that the first magnetic members 12 and the magnetic bases 13 are in one-to-one correspondence, thereby ensuring that the refrigerator 10 has high stability.

In other embodiments, the magnetic base 13 includes a supporting foot 132 and a plurality of second magnetic members 131, the supporting foot 132 has a larger contact area with the ground, for example, the area of the supporting foot 132 contacting with the ground is the same as the area of the bottom of the refrigerator main body 11, which further improves the stability of the refrigerator 10, and each second magnetic member 131 is respectively mounted on the supporting foot 132. The number of the second magnetic members 131 is the same as the number of the first magnetic members 12, and the mounting positions of the second magnetic members 131 on the support feet 132 correspond to the first magnetic members 12.

In some embodiments, the support foot 132 is a height-adjustable support member, as shown in fig. 2, the support foot 132 includes a bolt, a nut, and a support base, one end of the bolt is installed in a threaded hole provided in the nut, and the other end of the bolt is installed in a threaded hole included in the support base, and the height of the support foot 132 can be adjusted by rotating the nut. When the door of the refrigerator 10 is a non-push-pull type door, the supporting seat may be replaced with a lower hinge structure. The second magnetic member 131 is attached to the supporting base or the lower hinge.

In another embodiment, as also shown in fig. 2, to increase the friction between the support foot 132 and the ground and thus increase the stability of the support foot 132, an anti-slip cover may be nested at the end of the bolt that contacts the ground.

It should be noted that the height-adjustable support member corresponding to the support foot 132 is not limited to the structure shown in fig. 2, and any height-adjustable support member can be used as the support foot 132 of the present application. Through setting up height-adjustable's support footing 132, can drive the regulation of the height of first magnetic member 12 for the holistic height-adjustable of refrigerator 10 further promotes user experience.

It should be further noted that the utility model provides a refrigerator 10 still has common refrigerator parts such as compressor, cooling fan, fresh-keeping room, walk-in, and this department lists not one by one. In addition, the refrigerator has different refrigerator components for different types of refrigerators, such as an air-cooled refrigerator and a direct-cooled refrigerator.

The above description is only for the preferred exemplary embodiment of the present invention and is not intended to limit the embodiments of the present invention, and those skilled in the art can easily make various changes and modifications according to the main concept and spirit of the present invention, so the protection scope of the present invention should be subject to the protection scope claimed in the claims.
