One specific implementation of the refrigeration apparatus 100 according to the embodiment of the present disclosure is as follows:

the refrigerating apparatus 100 may be a refrigerator in which a damping mastic is attached to an inner side of a back of the refrigerator, the damping mastic being located on a noise radiation transfer path of a fan.

The noise of the fan is mainly transmitted by wind noise generated by flowing in the air duct and vibration generated by rotation of the fan. The vibration transmission generated by the rotation of the fan can be effectively reduced by adding the damping daub, and the noise with the low frequency of 400 Hz-800 Hz is mainly solved.

Specifically, as shown in fig. 3, fig. 3 is a graph comparing sound pressure levels of noise generated from the refrigerator in a case where the damping mastic is attached or not to the inside of the refrigerator.

Referring to fig. 3, a layer of damping mortar is added in the refrigerator, and the sound pressure level of the noise of the refrigerator with the damping mortar is obviously reduced in the range of the noise with the low frequency of 400 Hz-800 Hz.

It should be noted that, in the related art, noise of the refrigerator mainly comes from the compressor, the fan, and the refrigerant flow. At present, the noise is reduced by reducing the rotating speed of the fan, or the noise of the fan is reduced by optimizing the structural design of the air duct.

However, for the fans, after model selection and air duct design are completed, the period of change from design is very long (especially for some inlet fans), and meanwhile, the rotation speed of the fan required by refrigeration cannot be reduced without a bottom line.

In this disclosure, through attached shock attenuation daub on the refrigerator backplate, can reduce the noise transmission of fan, although there is the cost to rise, can shorten improvement cycle, the fan rotational speed also can not reduce again.

It should be noted that, in daily life, with the rapid development of user requirements and markets, the sales of large-volume high-end refrigerators are more and more. The existing large-volume multi-system refrigerators such as four cross doors, multiple French doors and other series have various operation modes and have clear compartment classification, so that the existing large-volume multi-system refrigerators generally have a complex refrigeration cycle system, wherein a plurality of fans which run at high speed are designed, such as a refrigeration fan, a freezing fan, a temperature-changing fan and the like. In the daily use process, when the refrigerator runs in a normal mode or a quick-freezing mode, the noise of the compressor is relatively large, the subjective perception of a user is obvious, and after the noise of the running of the fan is shielded by the noise of the compressor, the direct feeling of the user is not easy to cause. However, when the refrigerator enters a shutdown defrosting stage, the compressor stops operating, and at this time, the flow noise of the refrigeration system pipeline, the condensed water vaporization noise of the fin evaporator, and the noise of the air blowing defrosting operation of the refrigeration fan become key factors affecting the sound quality experience of the user, and easily cause noise complaints of the user on products.

Compare in prior art, the refrigerator in this disclosure, can also all lay the shock attenuation clay on the internal face of refrigerator, start from the actual problem that the noise improved, reduce fan running noise.

Further, according to the cold air circulation mode, the refrigerator is generally classified into an air-cooled refrigerator and a direct-cooled refrigerator, wherein the air-cooled refrigerator forces the air in the refrigerator to flow through an in-refrigerator fan, so that the temperature in the refrigerator is uniform, the cooling speed is high, and the use is convenient.

However, generally, the air-cooled refrigerator has low overall humidity and the fruit and vegetable food materials stored in the refrigerating chamber are seriously dried due to the blowing of the fan, so that the food materials are shriveled or even rotten to different degrees after being stored for a long time, and the edible value of the food materials is greatly reduced. Therefore, various moisture-preserving and humidity-adjusting drawers are developed in the refrigerator industry for solving the problem, but due to the limitation of the size of the drawer, the use requirement of a user for storing a large amount of fruit and vegetable food materials in a conventional refrigerating chamber at one time cannot be met. Therefore, the interior of the refrigerator can be humidified through ultrasonic humidification, defrosting water humidification or ion humidification, so that the requirement of a user on freshness preservation is met.

The ultrasonic humidification is that water mist is formed by high-frequency oscillation of the ultrasonic atomization sheet and is dissipated in air, so that space rapid humidification is realized. Although the technology can rapidly improve the humidity level in the space, the technology also has the defects of condensation caused by overhigh local humidity, poor reliability, easy failure and the like. And if the humidity in the refrigerator is increased, bacteria can be accelerated to breed if the refrigerator is not sterilized in time, and then food spoilage is accelerated.

The defrosting water humidification is to collect water defrosted by an evaporator and blow the water back to a refrigerating chamber by a humidifying material or a fan, but the technology has the problems of poor humidifying effect, sanitation, safety and the like.

The ion humidification is realized by decomposing free large water molecule clusters in the air into smaller water molecules and carrying ions through high-voltage ionization, and the charged water molecules are easier to be absorbed by fruits and vegetables than the free large water molecule clusters. However, this technique also has a problem of insufficient humidifying effect.

Further, most of the current refrigerator door seals are made of soft PVC materials. The PVC door seal mainly comprises PVC resin, a plasticizer, a filler and a plurality of stabilizers. The PVC door seal can cause the adhesion problem between the refrigerator door and the refrigerator body due to the defects of low thermal deformation temperature and easy migration of a plasticizer. Although the door seal can be structurally designed with the anti-adhesion bulge structure, the anti-adhesion effect is not obvious, and the anti-adhesion structure is easy to generate refrigerator condensation and energy consumption increase phenomena.

According to the refrigerator door seal structure, the anti-sticking coating can be arranged on the end face, facing the refrigerator body, of the refrigerator door seal, the inert chemical property of the anti-sticking coating is utilized, the defects that the refrigerator door seal is deformed when being heated and is easy to move are avoided, and therefore the refrigerator door seal with the anti-sticking coating is not prone to being adhered to the refrigerator body.
