The interior of the box body defines a storage compartment and a refrigerating air duct 30, the storage compartment defines a sub-storage compartment 20 and an air flow channel 70 positioned outside the sub-storage compartment 20, and the air flow channel 70 is communicated with the refrigerating air duct 30. The oxygen control device 41 comprises an electrolysis module for performing an electrochemical reaction with the gas in the sub-compartment 20 to consume oxygen in the gas in the sub-compartment 20, and the electrolysis module is partially or entirely located in the gas flow channel 70. The heat dissipation fan is used for blowing or exhausting air to the electrolysis module. The temperature sensor is arranged on the electrolysis module and used for acquiring the temperature of the electrolysis module so as to control the heat dissipation fan according to the temperature of the electrolysis module.
In the present embodiment, the electrolysis module is the main heat generating component of the oxygen control apparatus 41. In the operation process of the oxygen control device, the electrolysis module and the gas in the sub-storage compartment 20 perform electrochemical reaction, so that oxygen in the gas in the sub-storage compartment can be consumed. During the electrochemical reaction, the electrolysis module generates a large amount of heat. When the oxygen control device works, the heat dissipation fan can be controlled according to the temperature of the electrolysis module obtained by the temperature sensor, specifically, when the temperature of the electrolysis module is larger than a preset value, the heat dissipation fan is controlled to be started, the heat dissipation extension can enable larger air flow to be formed in the air flow channel, the air flow in the air flow channel can dissipate heat of the electrolysis module, and heat generated by the electrolysis module can be taken away.
Therefore, in the refrigerating and freezing device of the present utility model, since the air flow channel 70 is provided at the outer side of the sub-storage compartment 20 and the electrolysis module is partially or entirely located in the air flow channel 70, the temperature sensor is provided on the electrolysis module, so that the heat dissipation fan can be controlled according to the temperature of the electrolysis module obtained by the temperature sensor, when the heat dissipation fan is started, the heat dissipation fan blows or draws air to the electrolysis module, so that an air flow is formed in the air flow channel 70, and the air flow can take away the heat of the electrolysis module. Therefore, compared with the prior art, the utility model solves the problem that the existing oxygen control device 41 is not smooth in heat dissipation, and prolongs the service life of the oxygen control device 41. In addition, the utility model can avoid the problem of larger temperature fluctuation in the sub-storage compartments 20 caused by overhigh temperature of the control device.

In use, the gas flow in the gas flow channel 70 can flow not only along the outer peripheral surface of the electrolytic module, but also from the outer end surface of the electrolytic module. That is, the contact area of the gas flow with the electrolytic module is large.
In this embodiment, since the outer side of the outer end surface of the electrolysis module has a gap through which the air flow passes, the contact area between the air flow and the electrolysis module is increased, so that the heat exchange speed between the air flow and the electrolysis module is increased, and the heat dissipation efficiency and the heat dissipation effect can be further improved.

As shown in fig. 2, the cooling air duct 30 includes a first air outlet 31, and the first air outlet 31 is disposed corresponding to the air flow channel 70 to directly supply air to the air flow channel 70.
In this embodiment, after the cold air in the cooling air duct 30 is blown out through the first air outlet 31, the cold air can directly enter the air flow channel 70 to dissipate heat of the oxygen control device 41.
In the present embodiment, since the path of the cold air from the cooling air duct 30 to the air flow channel 70 is short, the temperature of the cold air passing through the oxygen control device 41 is relatively low, so that the heat dissipation efficiency and heat dissipation effect of the oxygen control device 41 can be improved.
