It should be noted that the number and the structure of the storage spaces 111 may be configured as required, and fig. 1 shows a case where a first space, a second space and a third space are sequentially arranged from top to bottom; the space can be configured into a refrigerating space, a freezing space, a temperature changing space or a fresh keeping space according to different purposes. In a preferred embodiment, the front side of the compressor housing 112 is provided with an air inlet (not shown) having a sound-damping structure. More preferably, the sound attenuation structure can be a perforated plate or sound absorption cotton to avoid the noise from transmitting out from the air inlet.

The air outlet duct 140 is disposed at the back of the box 110, extends vertically upward, and is communicated with the compressor housing 112 through the air outlet 132. The case 110 may include an inner container, a case, and a foaming layer filled between the case and the inner container. The foaming layer can effectively prevent the internal cold energy from losing. The air outlet duct 140 may be formed by a foaming layer on the back of the refrigerator 100. In a preferred embodiment, the cross-sectional area of the upper portion of the outlet duct 140 is smaller than the cross-sectional area of the lower portion to minimize the space occupied by the foam layer.

It should be noted that, because the air outlet duct 140 is disposed to thin the foaming layer, the possible cold leakage problem may be compensated by using a VIP (vacuum insulation panel) material. The vacuum insulation panel is one of vacuum insulation materials and is formed by compounding a filling core material and a vacuum protection surface layer. The vacuum insulation panel can effectively avoid heat transfer caused by air convection, so that the heat conductivity coefficient can be greatly reduced, and particularly, the heat conductivity coefficient can generally reach 0.002-0.004w/m.k, which is 1/10 of the heat conductivity coefficient of the traditional insulation material.

The refrigeration system is configured to provide cooling energy to the storage space 111, wherein the refrigeration system includes a fan 152 and a compressor 153 disposed in the compressor compartment 112, and the fan 152 is embedded in the outlet air duct 140. Therefore, a reasonable and feasible structure is provided, the effective heat dissipation of the compressor bin 112 is realized by the air outlet duct 140 and the fan 152, the normal work of the compressor 153 and other equipment is prevented from being influenced by the overhigh temperature of the compressor bin 112, and the service life is prolonged.

In practice, the type of refrigeration system is a compression refrigeration system, which provides different amounts of cooling to the refrigerated space and the refrigerated space, so that the temperatures in the refrigerated space and the refrigerated space are also different. Wherein the temperature in the refrigerated space is typically between 2 ℃ and 10 ℃, preferably between 3 ℃ and 8 ℃. The temperature range in the freezing space is typically between-22 ℃ and-14 ℃. The optimal storage temperatures of different kinds of food are different, and the storage spaces 111 suitable for storage are also different. For example, fruit and vegetable foods are suitable for storage in the refrigerated space, while meat foods are suitable for storage in the refrigerated space.

In a preferred embodiment, the air outlet duct 140 may further include a sound absorption structure (not shown) inside to further reduce noise. More preferably, the sound absorption structure is disposed in the middle of the outlet duct 140. In addition, the sound absorption structure can be in a water drop shape to reduce fluid resistance and improve heat dissipation performance. The sound absorbing structure may also be a micro-perforated plate or sound absorbing cotton to further absorb the sound leaking from the outlet duct 140 and the noise generated by the fan 152 in the compressor housing 112.
