Description

A refrigerator with a cooler

technical field

The invention relates to a refrigerator, in particular to a refrigerator with a cool accumulator.

Background technique

At present, in the refrigeration products of freezers and refrigerators, during the cooling process of the refrigeration system, the cooling capacity of the internal compartments is also continuously lost. Therefore, in order to ensure that the temperature of the internal compartments is stable within the required range, the refrigeration system must continue or It is intermittent operation to supplement the lost cooling capacity, and the quality of product insulation directly affects the energy consumption level of the product. In some developing countries or regions where power outages are frequent, in order to avoid food deterioration during power outages, there is a higher requirement for the insulation effect of the product.

Under normal circumstances, refrigeration products generally improve the insulation effect by using better insulation materials, appropriate foam density, and increasing the thickness of the insulation layer. However, these solutions are limited by the cost of insulation materials, product size and volume requirements. In the medical field that requires high temperature control and heat preservation, there are also ways to increase the heat preservation effect of the product by adding a cold storage device, but generally a double-layer inner tank is used, as shown in Figure 1. A double-layer inner tank with a cold storage device The refrigerator comprises a box shell 14, an outer liner 11, an inner liner 13 and a foam layer 15 arranged between the inner liner 13 and the box shell 14, and an evaporator 12 is arranged on the outside of the inner liner 13, which is placed on the outer liner 11 One or more layers of regenerators 16, and a layer of inner tank 13 and decorative strips are assembled outside the regenerators 16. This structure not only greatly reduces the effective volume of the product, but also has complicated manufacturing processes and a large increase in cost, which cannot be used in civilian applications. field promotion.

Contents of the invention

The object of the present invention is to solve the above problems and provide a refrigerator with a regenerator with no change in product volume, simple manufacturing process, good cold storage effect and low cost.

The purpose of the present invention is to realize through the following technical solutions:

A refrigerator with cold accumulator, comprising a case shell and an inner container, an evaporator and a cold accumulator are placed in sequence between the outer wall of the inner container and the case shell, the evaporator is placed close to the cold accumulator, the inner container and the case The remaining spaces between the shells are filled with foaming insulation materials. After the foaming insulation materials are foamed, the cold accumulator is buried between the foaming insulation materials and the inner wall.

Further, a groove is formed on the side of the cold accumulator close to the outer wall of the inner tank, the evaporator is placed in the groove, the evaporator and the cold accumulator are closely matched, and the effect of cold transfer and cold storage is good.

Preferably, the cold accumulator is made of plastic blow molding, and the evaporator is a coiled tube evaporator with good cooling effect.

Preferably, the regenerator is composed of a regenerator box and a cold storage liquid contained in the regenerator box, the regenerator box is a flat rectangular structure, and the cold storage liquid is distilled water or sodium chloride solution.

The beneficial effect of the present invention is that the refrigerator with cold accumulator attaches the cold accumulator to the outer wall of the inner container without using a double-layer inner container, does not change the effective volume of the product, and has simple manufacturing process and low cost. , the evaporator is set in the groove provided by the cold storage device, and it is closely matched, and the effect of cold transfer and cold storage is good. In addition, compared with the double-layer liner with cold storage refrigerator, the evaporator of the present invention is closer to the internal compartment, and the cooling temperature The pull-down speed is relatively fast, and the cold preservation effect is good after power failure.

Detailed ways

Please refer to Fig. 2, in the present embodiment, a kind of freezer with regenerator, comprises box shell 24, liner 21, between described liner 21 outer wall and box shell 24, place evaporator 22 and Cold accumulator 26, said cold accumulator 26 has a groove on the side close to the outer wall of inner container 21, and said evaporator 22 passes through the groove on said cold accumulator 26, and said cold accumulator 26 is made of plastic blow molding The evaporator 22 is a coiled tube evaporator, and the regenerator 26 is composed of a regenerator box and a cold storage liquid 25 contained in the regenerator box, and the regenerator box is a flat rectangular structure. The cold storage liquid 25 is distilled water, and the remaining space between the inner tank 21 and the case shell 24 is a foam layer 23 filled with foam insulation materials.

During installation, the regenerator 26 is directly attached to the outer wall of the inner tank 21 without changing the volume of the product, and after the foaming insulation material is foamed, the regenerator 26 is buried between the foaming insulation material and the inner tank 21 .

When working, the refrigeration compressor starts, and the evaporator 22 arranged on the outer wall of the inner tank absorbs heat and refrigerates, and releases cold energy evenly to the regenerator 26 and the internal space. When the temperature is lowered, during normal use, when the refrigeration system is running or stopped, the cold storage of the cold accumulator and the release of cold energy to the internal compartment make the temperature fluctuation range of the internal space smaller than that of ordinary refrigerators, and the temperature is more stable. When the refrigeration compressor stops working due to a power outage or other emergencies, the cold accumulator 26 releases cold energy to the internal compartment of the product, and the internal space absorbs the cold energy released by the cold accumulator 26 to achieve a cold preservation effect, making the internal temperature fluctuation more than that without the cold accumulator. The temperature fluctuation of the product in the same period of time is smaller, which can avoid or reduce the loss of users to a certain extent.

During the cooling process of the product, since the cold storage device 26 is close to the evaporator 22 to absorb part of the cooling capacity, the cooling temperature of the internal compartment of the product will drop slower than that of ordinary products without a cold storage device, but compared with the double-layer inner tank In the freezer with cold accumulator, the evaporator 22 of the present invention is closer to the internal space of the product, and the cooling temperature is pulled down relatively quickly. When the refrigeration depth reaches the use process, the internal temperature fluctuation range of the product with cold accumulator is small, and after power off The temperature rise time is much better than ordinary products without cold storage.

The above embodiments have only set forth the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. On the premise of not departing from the spirit and scope of the present invention, the present invention also has various changes and changes. These changes and changes are all fall within the scope of the claimed invention.
