In any of the above-described embodiment, it is preferable that when starting cooling to freezing compartment, detect the indoor temperature of freezer
Whether 0 DEG C is greater than, further includes: when starting cooling to freezing compartment, the seal chamber of humidifier is begun to warm up, it is residual to carry out
Ice is removed；When detecting that heating duration reaches preset duration threshold value, stop heating.
In this embodiment, by the way that when detecting freezing compartment's starting cooling, the temperature in seal chamber is reduced, in seal chamber
Water freezing, influence the work of humidifier in seal chamber, at this point, heating device is opened, reduce the water freezing in seal chamber
Phenomenon carries out residual ice removing to the outlet in mist channel out, prevent from humidifying due to last time in water mist freeze in mist channel condensed water out
Blocking, the water droplet of thawing are discharged from drainage channel, prepare for the humidification work of humidifier, when detecting that heating duration reaches
When preset duration threshold value, heating device is closed, on the one hand, is reduced the energy consumption of heating device, on the other hand, be ensure that close
Seal the normal operation of intracavitary humidifier.
Furthermore it is also possible to which heating device is closed when detecting that the indoor temperature of freezer is greater than 0 DEG C.
In any of the above-described embodiment, it is preferable that further include: be less than in the temperature for the seal chamber for detecting humidifier or
When equal to 0 DEG C, the seal chamber of humidifier is heated, until stopping adding when detecting that the temperature of seal chamber is greater than 0 DEG C
Heat.
In this embodiment, temperature when being less than or equal to 0 DEG C by the temperature inside detection humidifier, in seal chamber
It reduces, the water freezing in seal chamber influences the work of humidifier in seal chamber, at this point, heating device is opened, maintains closing chamber
Interior temperature is not less than 0 degree, prevents the influence by interior lower than 0 degree of temperature from making so that the water in humidifier is frozen in
The humidification function of humidifier normally executes in seal chamber.
