An exhaust assembly 2, the exhaust assembly 2 comprising an airflow driving part 21 and an exhaust pipe 22, the airflow driving part 21 having an air suction port and an air outlet port, the airflow driving part 21 being configured to suck air from the air suction port and exhaust air from the air outlet port, the air outlet port being connected to the exhaust pipe 22;

wherein the compressor, the condenser 4 and the throttling device are arranged in the machine cabin 12, and the evaporator 3 is arranged in the evaporation cavity 111; the exhaust pipe 22 is communicated with the storage chamber 11 and is used for sucking and discharging the peculiar smell gas in the storage chamber 11 to the outside of the storage chamber 11, and the exhaust pipe 22 extends to the outside of the storage chamber 11.

Specifically, in the use process, after the airflow driving part 21 is started, the airflow driving part 21 can suck the air in the storage chamber 11 through the exhaust pipe 22, and the fresh air channel 13 can synchronously introduce and convey the external air into the storage chamber 11.

In an embodiment of the present application, in order to reduce the manufacturing cost and improve the ventilation efficiency of the fresh air in the storage chamber 11, the exhaust assembly 2 is configured with an airflow driving component 21 to suck the fresh air and discharge the dirty air in the storage chamber 11, so as to realize the function of ventilation.

Meanwhile, in order to improve the efficiency of exchanging fresh air, the air suction port of the air flow driving part 21 is arranged near the air return port of the evaporation cavity 111.

Specifically, during the use process, the storage room 11 closes the internal storage space through the door body, the storage space in the storage room 11 is in a relatively closed state, and the air quality in the storage space in the storage room 11 is affected by the peculiar smell generated by the flavored articles stored in the storage space, so that the fresh air exchanging treatment on the storage space in the storage room 11 needs to be realized through the exhaust component 2.

During the fresh air exchange, the door of the storage chamber 11 is in a closed state, and after the airflow driving part 21 is energized, the airflow driving part 21 can suck the airflow flowing to the return air inlet of the evaporation cavity 111 through the air suction port.

The cool air outputted from the evaporation chamber 111 generally exchanges heat with the articles stored in the storage chamber 11 and then flows back into the return air inlet of the evaporation chamber 111. Therefore, for the air in the storage chamber 11, the air quality at the return air inlet of the evaporation cavity 111 is the worst.

When fresh air is exchanged, as the air suction port of the air flow driving component 21 is arranged close to the air return port of the evaporation cavity 111, and then the air sucked through the air suction port of the air flow driving component 21 is basically polluted air in the storage chamber 11, so that polluted air in the storage chamber 11 can be sucked and discharged to the outside of the storage chamber 11 through the exhaust pipe 22 quickly and efficiently, and the fresh air exchanging efficiency is improved.

In addition, when the airflow driving component 21 operates, the air suction process is performed on the interior of the storage chamber 11 through the air suction port, so that a certain negative pressure is formed in the storage cavity of the storage chamber 11, and under the action of the negative pressure, new air outside the storage chamber 11 can enter the storage cavity of the storage chamber 11 through the new air channel 13, so that no additional independent fan or other components are required for driving the new air.

By arranging the normally open fresh air channel 13 communicated with the outside on the storage chamber 11, the introduction of fresh air and the discharge of dirty air can be realized by the action of a single air flow driving part 21 on the storage chamber 11, and independent parts for the fresh air and the exhaust air are not required to be respectively arranged for driving the air flow, so that the manufacturing cost is reduced, the integral structure is simplified, and the occupied space of the exhaust assembly 2 in the box body 1 is reduced; in addition, for the air flow driving component 21, the air suction port is arranged at the air return port of the evaporation cavity 111 to suck air, so that the dirty air in the storage cavity can be quickly and efficiently sucked and discharged to the outside of the storage chamber 11 through the exhaust pipe 22, the fresh air ventilation efficiency is improved, the running time of the air flow driving component 21 is shortened, and the energy consumption is reduced.

Specifically, for the evaporation cavity 111 disposed in the storage chamber 11, the air return port of the evaporation cavity 111 is disposed in the bottom area of the storage chamber 11, and the air outlet of the evaporation cavity 111 is disposed in the top area of the storage chamber 11, during the refrigerating process, the cold air in the evaporation cavity 111 after heat exchange by the evaporator 3 is output from the air outlet, and the principle of cold air descent is utilized, so that the cold air flows downward and flows to the air return port of the evaporation cavity 111 after heat exchange by the articles stored in the storage chamber 11.

For the fresh air introduced from the fresh air channel 13 into the storage cavity of the storage chamber 11, the fresh air is conveyed to the air return opening through the connecting air duct 14 arranged in the storage chamber 11, so that the fresh air is mixed with the air after heat exchange in the storage cavity of the storage chamber 11 in the air return opening and then enters the evaporation cavity 111 for heat exchange and refrigeration. Therefore, the newly introduced air is also cooled by the evaporator 3 and then is output into the storage cavity from the air outlet, so that the objects in the storage cavity are cooled, and the temperature rise in the storage cavity caused by the introduction of the fresh air is further reduced.

In some embodiments, in order to reduce the air suction port of the air flow driving component 21 from sucking excessive fresh air during the air suction process to affect the heat exchange efficiency of the fresh air, the outlet of the connecting air duct 14 is higher than the air suction port in the height direction.

Specifically, for the design of the positional relationship between the outlet of the connection duct 14 and the air suction port of the air flow driving member 21, the outlet of the connection duct 14 is arranged above the air suction port of the air flow driving member 21.

In a certain embodiment, in order to realize that the storage cavity is internally and evenly supplied with cold air, the air duct cover plate 18 is further covered on the evaporation cover plate 17, an enclosure 19 is arranged between the air duct cover plate 18 and the evaporation cover plate 17, the enclosure 19 surrounds the outside of the air outlet, the air return opening is positioned outside the enclosure 19, an air outlet cavity is formed between the enclosure 19, the air duct cover plate 18 and the evaporation cover plate 17, a plurality of air outlet holes 181 are formed in the air duct cover plate 18, and the air outlet holes 181 are communicated with the air outlet cavity.

Specifically, the cool air output from the air outlet of the evaporation cavity 111 is first delivered to the air outlet cavity formed at the back of the air duct cover 18, and the cool air fills the air outlet cavity and is output through the plurality of air outlet holes 181 arranged on the air duct cover 18. The cool air is outputted through the plurality of air outlet holes 181 arranged on the air duct cover plate 18, so that the cool air can be uniformly distributed in the storage cavity, and the refrigerating uniformity is improved.

The air suction port of the air flow driving component 21 is arranged below the air return port and is close to the lower edge of the air channel cover plate 18, so that the air suction port of the air flow driving component 21 can be used for sucking the dirty air in the storage cavity more efficiently.

Meanwhile, the bottom of the air duct cover plate 18 can be lower than the bottom of the second concave structure 16, so that fresh air can flow towards the air return opening at the inner side of the air duct cover plate 18, the fresh air is reduced to be sucked by the air suction opening of the air flow driving component 21, and the ventilation efficiency of the fresh air is further effectively improved.

The condenser 4 is high in temperature, the air flow driving part 21 works and discharges the fin heat exchange of the low-temperature air condenser 4, so that the temperature of the condenser 4 is reduced, the efficiency of a refrigerating system is improved, and the interference of low-temperature gas discharge to the actual use environment of a user is avoided. Under the action of the condensing fan in the cabin 12, the gas exhausted by the exhaust pipe 22 is communicated with the gas sucked from the outside of the cabin 12 and flows through the condenser 4 together to participate in heat exchange.
