The refrigeration system comprises a first evaporator 64 placed in the refrigerating compartment 4 and a second evaporator 65 placed in the interlayer 2. An automatic air blowing device is arranged in the interlayer 2 and blows cold air into the refrigerating chamber 4.

Based on the above technical solution, the second evaporator 65 is disposed in the interlayer 2, and the interlayer 2 is a relatively independent space communicated with the refrigerating chamber 4. First, the second evaporator 65 is disposed in the interlayer 2, which does not cause waste of cooling, and the cool air in the interlayer 2 and the cool air in the refrigerating chamber 4 can transfer heat and cool, i.e., the second evaporator 65 can also cool the refrigerating chamber 4. Then, the second evaporator 65 is placed in the compartment 2, and an automatic air blowing device is provided in the compartment 2, and when the door 5 is opened, the automatic air blowing device blows cool air into the refrigerating compartment 4, specifically, the automatic air blowing device sucks in outside air, cools the air by the second evaporator 65, and finally blows the cooled air into the refrigerating compartment 4. The automatic air blowing device has the following effects of air blowing operation: firstly, cold air is quickly supplemented in the refrigerating chamber 4, so that the phenomenon that when the refrigerator door is opened, the cold air in the refrigerating chamber 4 with a small space can quickly run off to cause the temporary loss of the refrigerating effect of the refrigerating chamber 4 is avoided, after the refrigerator door 5 is closed, the air close to the normal temperature in the refrigerating chamber 4 needs to be cooled, the cooling time is long, and some articles with high requirements on the refrigerating temperature are deteriorated; secondly, in order to realize the quick ventilation in the refrigerating chamber 4, the problem of sudden temperature drop in the refrigerating chamber 4 can not occur in the ventilation process, and the influence on refrigerated objects is avoided.

As shown in fig. 1 and 2, the sandwich 2 according to the present invention comprises a first zone 21 and a second zone 22 separated by a partition 27. An air inlet 24 is arranged at the top of the first area 21, and an electromagnetic valve 23 is arranged on the air inlet 24. A filter plate 28 is detachably provided inside the air inlet 24. The partition 27 is provided with a through hole 25 communicating the first section 21 and the second section 22, the end of the through hole 25 near the first section 21 is provided with a fan 26, the second evaporator 65 is disposed in the second section 22, and the side of the second section 22 facing the refrigerating compartment 4 is provided with an air opening 29.

Based on the above technical solution, when the box door 5 is closed, the box door 5 presses the limit switch 41, and the limit switch controls the electromagnetic valve 23 and the fan 26 to be closed. At this time, the second evaporator 65 cools the air in the interlayer 2, at this time, the interlayer 2 is communicated with the refrigerating chamber 4, and the cold air in the interlayer 2 and the cold air in the refrigerating chamber 4 are convected, that is, the second evaporator 65 cools the refrigerating chamber 4. When the door 5 is opened, the door 5 releases the limit switch 41, the limit switch controls the solenoid valve 23 and the fan 26 to be started, and the fan 26 blows the air in the first area 21 to the second area 22 and finally enters the refrigerating chamber 4 through the air opening 29. While the fan 26 is operated, external air is introduced into the first section 21 through the solenoid valve 23 and the air inlet 24, thereby achieving air replenishment of the first section 21 and the refrigerating chamber 4. The filter sheet 28 is used to remove impurities such as dust from air.

As shown in fig. 2, a pressure sensor and a limit switch 41 are arranged in the refrigerating chamber 4 according to the technical scheme of the invention, the pressure sensor is connected with a controller arranged in the refrigerating work area 6 through signals, and the limit switch 41 is electrically connected with the controller and is switched on and off by opening and closing the door 5. The controller is in signal connection with the solenoid valve 23, the fan 26 and the refrigeration system. The refrigeration system includes a compressor 61, a condenser 62, and a liquid storage tank 63. The liquid outlet end of the condenser 62 is provided with a tee joint 66, and the first evaporator 64 and the second evaporator 65 are respectively connected with the tee joint 66. Liquid outlet ends of the first evaporator 64 and the second evaporator 65 are both connected with a liquid storage tank 63, and the liquid storage tank 63 and the condenser 62 are respectively connected with an inlet and an outlet of the compressor 61.

As shown in fig. 1, 3 and 4, the refrigerator door 5 according to the present invention is movably connected to the refrigerator body 1. Connecting columns 51 are respectively arranged at the top and the bottom of the refrigerator door 5, supporting blocks 52 respectively penetrate through the two connecting columns 51, and the two supporting blocks 52 are respectively fixedly connected with the top and the bottom of the refrigerator body 1. The supporting block 52 is provided with a large through hole 55, and the connecting column 51 passes through the large through hole 55 and can move in the large through hole 55. A fixed column 53 is also fixed on the supporting block 52, and a return spring 54 is connected between the fixed column 53 and the connecting column 51. As shown in fig. 5, which is a schematic view of the state of the door 5 during the opening process, the return spring 54 is in the original length state 54 in both the closed and fully opened states of the door 5. The inner side of the box door 5 is provided with a sealing magnetic strip and a sealing rubber strip.

Because the single-door cold box refrigerator is small in size, in the household placement, the single-door cold box refrigerator and the cabinet 10 and the like are mostly integrated and placed in the cabinet 10, and the fusion and the reasonable utilization of space are realized. Based on the technical scheme, the door 5 can move in the direction away from the cabinet 10 in the opening process, so that the problem that the door 5 interferes with the cabinet in the opening process is effectively solved. At the same time, the return spring 54 may effectively control or limit the path of movement of the door 5, particularly to facilitate the return of the door 5 during closing. The return spring 54 is in the original length state in both the closed and fully opened states of the door 5, ensuring that the door 5 is kept in the opened state in the fully opened state without external fixation. Meanwhile, when the refrigerator door 5 is not in a fully opened state, after a person leaves, the refrigerator door 5 can be automatically closed under the action of the return spring 54, sealing is realized by the sealing magnetic strip and the sealing rubber strip, and the phenomenon that the refrigerator door 5 is forgotten to be closed to cause the refrigeration effect of the refrigerator is avoided.

As shown in fig. 6, in order to more clearly express or represent a schematic view that the return spring 54 is in an original length state in both the closed and fully opened states of the door 5, a portion where the door 5 is connected to the refrigerator body 1 in fig. 5 is partially enlarged.
