Specifically, the quick-freezing chamber 101 configured in the refrigeration apparatus of this embodiment is not provided with an air return portion directly connected to the air duct, the cold air in the quick-freezing chamber 101 is reheated and exchanged and then directly conveyed to the refrigerating compartment 102, and the air return of the air duct 2 is realized through the refrigerating compartment 102, that is, the cold air output by the first air outlet 21 enters the quick-freezing chamber 101, is subjected to heat exchange, and then returns to the air duct 2 through the refrigerating compartment 102, so that in the quick-freezing mode, the cold air formed by heat exchange in the evaporator 3 sequentially flows through the quick-freezing chamber 101 and the refrigerating compartment 102 and then returns to the air duct 2 from the air return port 22. Thus, in the process of quick-freezing and refrigerating, after the articles to be quick-frozen are put into the quick-freezing chamber 101, because the temperature of the articles is high, even if the refrigerating equipment runs at full load, the cold air entering the quick-freezing chamber 101 at the initial stage can be heated to a high temperature, but the air output from the quick-freezing chamber 101 returns to the air duct 2 after passing through the refrigerating chamber 102, so that the cold energy contained in the storage in the refrigerating chamber 102 can be fully utilized to further refrigerate the air output from the quick-freezing chamber 101 in an auxiliary manner, and because the storage space of the refrigerating chamber 102 is large in cold accumulation, the air output from the quick-freezing chamber 101 is refrigerated by utilizing the existing cold energy in the refrigerating chamber 102 and then flows back to the air duct through the return air inlet, the cold air temperature after heat exchange of the evaporator 3 can be kept in a low temperature state all the time to increase the quick-freezing efficiency of the quick-freezing chamber 101, the time required by quick freezing is greatly shortened, so that the full-load running time of the refrigeration equipment is shortened, and the energy consumption is effectively reduced.
A temperature sensor (not marked) is arranged in the quick freezing chamber 101, and the temperature of the articles in the quick freezing chamber 101 is detected by the temperature sensor to judge whether quick freezing is finished; similarly, a weight sensor can be arranged in the quick-freezing chamber 101 to weigh the weight of the articles to be quick-frozen in the quick-freezing chamber 101, so that the refrigerating capacity required by the articles to be quick-frozen can be calculated to control the operation time of the quick-freezing mode.
In addition, there are various layout ways of the freezing chamber 101 and the refrigerating chamber 102 in the refrigerating apparatus of this embodiment, for example: as shown in fig. 1, the evaporator 3 is disposed at the back of the box body 1, the quick-freezing chamber 101 is disposed at the top of the box body 1, the refrigerating chamber 102 is located below the quick-freezing chamber 101, and the air return opening 22 is located at the bottom of the refrigerating chamber 102, at this time, the fan 4 may be disposed at the air outlet side of the evaporator 3, or the fan 4 is disposed at the first air outlet 21; similarly, as shown in fig. 2, the evaporator 3 is arranged at the top of the box body 1, the refrigeration compartment 102 and the instant freezing compartment 101 are arranged up and down, and the air return opening 22 is positioned at the top of the refrigeration compartment 102.
Further, in order to improve the distribution uniformity of the refrigeration temperature of the refrigeration equipment in the normal refrigeration mode, as shown in fig. 3, the air duct 2 is provided with a second air outlet 23 (not labeled) communicating with the refrigeration compartment 102. Specifically, the cold air heat-exchanged by the evaporator 3 in the air duct 2 can be directly conveyed to the refrigerating compartment 102 through the second air outlet 23, so that the distribution of the refrigerating capacity in the quick-freezing chamber 101 and the refrigerating compartment 102 in the box body 1 can be ensured to be more uniform in a common refrigerating mode. Preferably, in order to ensure that all cold energy generated by the evaporator 3 enters the quick-freezing chamber 101 firstly in the quick-freezing mode, the air duct 2 is provided with an air door for opening and closing the second air outlet 23, and the air door closes the second air outlet 23 in the quick-freezing mode, so that all cold energy generated by the evaporator 3 enters the quick-freezing chamber 101 firstly for quick freezing, and the quick-freezing efficiency is improved. Further, the fan 4 includes a first sub-fan 41 and a second sub-fan 42, the first sub-fan 41 is disposed on the first air outlet 21, and the second sub-fan 42 is disposed on the air outlet side near the evaporator 3, specifically, the first sub-fan 41 is mainly used for accelerating the amount of cold air entering the quick-freezing chamber 101 in the quick-freezing mode, and the second sub-fan 42 is mainly used for ensuring the circulation flow of cold air in the air duct 2 in the normal mode, so as to make the distribution of cold energy in the box 1 uniform.
