Technical Field

[0002] Traditional side-by-side refrigerators have internal components such as freezing air duct components, refrigeration air duct components, refrigeration tank, freezing tank, and freezing evaporator. The freezing evaporator generates cold energy, and the freezing air duct transfers part of the cold energy to the freezing room, and the other part is transferred to the refrigeration air duct component to refrigerate the refrigeration room. In order to control the temperature of the freezing room and the refrigeration room, the traditional refrigeration and freezing tank structures each require air ducts and corresponding condensing fans. The design of the two air duct structures occupies a large space and is expensive, which increases the production cost of the refrigerator. At the same time, workers are required to assemble them separately, which increases production hours.

[0003] In the existing structure, in the double-door refrigerator, there is a structure in which the air duct is placed on the top of the freezer compartment. In this solution, the condensing fan is also required to blow cold air into the refrigeration compartment and the freezer compartment through the refrigeration air duct and the freezing air duct placed at the rear of the box to achieve refrigeration. The internal space utilization rate of the refrigerator is insufficient, and the actual volume of the product only occupies four-fifths of the volume of the box space (the actual volume of the product needs to remove the volume of the refrigeration space. For example, for a refrigerator with a 500-inch inner tank depth, the depth of the back air duct of 100 is removed, and the actual use depth is 400). At the same time, the occupied use space seriously affects the user experience, and it is impossible to better experience the large-volume door opening experience of the open-door refrigerator.

[0024] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings:

[0025] like Figures 1 to 5As shown, a refrigerator refrigeration system includes a box body 1, an inner tank 2 installed inside the box body 1, and an insulation layer filled and arranged between the box body 1 and the inner tank 2, wherein the inner tank 2 is a whole large inner tank space, and a middle support component 4 is vertically installed at a designated position in the middle of the inner tank 2 according to actual production needs, and the internal space of the inner tank 2 is divided into two accommodating chambers, one on the left and one on the right. The accommodating chamber on the left is a refrigerator chamber, and the accommodating chamber on the right is a freezer chamber, and a freezing air duct component 3 is fixedly installed on the rear side wall of the freezer chamber; the interior of the middle support component 4 is filled with insulation foam to play a role in heat insulation on both sides, and at the same time, a middle air duct structure 10 is provided at the upper end of the middle support component 4, which is used to transfer the cold in the freezing air duct component 3 to the refrigerator chamber. A refrigeration chamber is provided at the lower rear side of the box body 1, in which a compressor and a condenser are installed to provide cold energy for the entire refrigerator refrigeration system. An evaporator is installed corresponding to the lower part of the interlayer between the inner tank 2 and the box body 1. The cold energy generated by the evaporator enters the freezing air duct assembly 3 through the condensing fan, and then enters the freezing chamber to achieve cooling.

[0026] A freezing side air outlet 8 is provided below the rear side wall of the freezing chamber, and a refrigerating side air outlet 7 is provided below the rear side wall of the refrigerating chamber. The refrigerating side air outlet 7 is arranged at a position higher than the freezing side air outlet 8, and a return air duct assembly 6 is arranged behind it. The return air duct assembly 6 is a hollow multi-section bent square tube structure, and its cross section is in the shape of an inclined bracket "]". Both outlet ends of the return air duct assembly 6 are provided with connecting pieces extending outward, and are fixedly mounted on the rear side wall of the inner liner 2 through the connecting pieces, and are relatively sealed. One end thereof corresponds to the refrigerating side air outlet 7, and the other end corresponds to the freezing side air outlet 8, so that the refrigerating chamber and the freezing chamber are connected, and at the same time, it is convenient for the sinking return air of the cold amount; the inner diameter setting size of the two outlet ends of the return air duct assembly 6 is larger than the setting size of the corresponding refrigerating side air outlet 7 or the refrigerating side air outlet 8.

[0027] A middle vertical beam assembly 5 is provided at the front side of the inner liner 2, corresponding to the position of the middle support assembly 4, and is installed before foaming. The upper and lower edges of the inner liner 2 are respectively provided with embedded fixed installation grooves 9, which are located on the same vertical line. The upper and lower ends of the middle vertical beam assembly 5 are respectively inserted into the upper and lower fixed installation grooves 9, and the front side of the middle vertical beam assembly 5 is flush with the front edge of the inner liner 2; the middle vertical beam assembly 5 plays a supporting and installing role for the inner liner 2 and the middle support assembly 4.

[0028] The specific operating principle is as follows: the compressor in the refrigeration room is connected to the condenser to transport the refrigerant to the evaporator, and the evaporator generates cold energy. Part of the generated cold energy passes through the condensing fan and the freezing air duct assembly 3 and enters the freezing room, and the other part of the cold energy is transferred to the inside of the return air duct assembly 6 through the temperature, and enters the cold storage room along with the wind flow for refrigeration; the freezing temperature in the freezing room spreads from bottom to top until it fills the entire freezing room, and then enters the cold storage room through the middle air duct structure 10 at the upper end of the middle support assembly 4 to cool the cold storage room, and the cold energy entering the cold storage room sinks from the cold storage side outlet 7 into the return air duct assembly 6 to complete the return air.

[0029] The utility model also provides a double-door refrigerator, which adopts the above-mentioned refrigerator refrigeration system, controls the refrigeration capacity of the two compartments through air doors to complete the cold capacity distribution, instead of the existing structure in which the air is transported from the freezing air duct to the refrigeration air duct to cool the refrigeration compartment, thereby improving the refrigeration uniformity of the system and helping to improve the overall efficiency of the refrigerator.

[0030] A further optimized technical solution is that the above-mentioned middle support component 4 is of segmented combination design and multi-layer installation. It can be detachably fixed from the side to the middle vertical beam component 5 and the inner tank 2, and is spliced ​​and sealed to each other to provide overall thermal insulation. At the same time, a middle air duct structure 10 with a hollow structure is added to the middle support component 4 at the upper end, so that the cold air volume in the freezer compartment is transferred to the refrigerator compartment. At this time, the refrigeration duct component in the refrigerator compartment is cancelled, which solves the problem that traditional side-by-side refrigerators require two necessary components, the refrigeration duct and the freezing duct, to transport cold air. Through innovative structural design, the space utilization rate is improved. For the side-by-side refrigerator using this solution, the actual internal volume of the refrigerator is about one-fifth larger than that of a traditional refrigerator. Taking a 500L refrigerator as an example, the cost is reduced by about 130 yuan, which has a significant cost advantage.

[0031] The positions of the freezing chamber and the refrigerating chamber are determined according to actual production conditions, and the left and right positions of the inner container 2 are determined. The corresponding structures arranged inside the inner container 2 are also installed and changed accordingly according to the changes in the positions.

[0032] The relevant technical features that have not been described in detail in the above embodiments can be realized by adopting or referring to the corresponding relevant technical solutions in the prior art.

[0033] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
