Description
Technical Field
The utility model relates to refrigeration and freezing equipment, and particularly provides refrigeration equipment with a magnetic field fresh-keeping device.
Background
When the existing refrigeration equipment (comprising a refrigerator, a freezer and the like) stores food materials such as meat, fish, shrimps and the like, the juice of the meat is easy to lose, and then the meat of the fish and the shrimp is deteriorated, so that the nutrition is lost and the taste is poor.
Research shows that the magnetic field can inhibit the growth of microorganisms and molds and prolong the storage period of the food materials. Therefore, the magnetic field can be used for assisting in storing the food materials, and the aim of prolonging the storage period of the food materials is fulfilled. When the magnetic field is used for assisting in storing food materials, the free path of water molecules is limited to a certain extent by the magnetic field, and the specific expression is that hydrogen bonds in a water molecule cluster are broken. The crystal nucleus growth of water is inhibited in the phase change process, the growth rate of ice crystals is higher than the migration rate of water molecules, and the generated ice crystals are smaller, so that the damage to cells is smaller, the loss rate of juice in food materials is reduced, and the nutrition and the taste of the food materials can be better preserved.
In order to achieve freshness preservation storage, the magnetic field needs to be matched with the storage temperature. According to practical tests, the storage temperature is preferably kept at 5-8 ℃ under the condition of non-freezing and fresh-keeping storage, and the cooling speed is required to be relatively stable. However, in the process of applying a magnetic field to the fresh-keeping space, the magnetic field generating device (generally, an electromagnetic device) generates heat, which causes temperature fluctuation and affects the quality of stored goods.

The first magnetic member 311 and the second magnetic member may be electromagnetic rings formed by winding electromagnetic coils, and may have a circular, oval or square shape, and a flat shape, and the top and bottom are both planar, and the thickness is significantly smaller than the outer peripheral dimension. The heat generated by the magnetic field assembly can be taken away by the surrounding air duct, so that the temperature influence on the fresh-keeping space 23 is reduced.
Alternatively, the magnetic field assembly in this embodiment may also use permanent magnets as the magnetic field elements, for example magnetic plates made of permanent magnets arranged at the top and bottom of the drawer. In addition, a magnetic field may be generated by using a combination of an electromagnetic coil and a permanent magnet, and superimposing them.
The magnetic field is helpful for improving the quality of stored food, shortening the freezing time, reducing the juice loss rate and nutrition loss of food, reducing the number of microorganisms and bacteria, and prolonging the preservation period. And the magnetic refreshing apparatus 20 is configured to form a circulating air duct for making the air flow from the air inlet 231 to pass through the top wall 221 of the barrel 22, the front baffle 215 of the drawer 21 and the space below the drawer bottom plate and return to the air return opening 232 in sequence, so as to refrigerate the refreshing space 23. Further the geomagnetic field is matched with the temperature control, the surrounding air channel is utilized to refrigerate the fresh-keeping space 23, and cold air can also take away heat generated by the electromagnetic coil during working in time, so that temperature fluctuation of the fresh-keeping space 23 is avoided, the effects of temperature and the magnetic field are integrated, and the fresh-keeping effect of food in the fresh-keeping space 23 is improved.
