When being worked due to electrolysis deoxygenation component 200, the oxygen in storage space is consumed, will lead to storage space air pressure inside
It gradually decreases.Therefore, the storage drawer 100 of electrolysis deoxygenation component 200 is installed, is easier to produce with extraneous inside storage space
Raw pressure difference opens drawer to user and causes difficulty.The refrigerating device of the present embodiment is detected in touch-sensing device 500
Storing will be opened to user to take out, when 100, electric-air valve 300 is performed fighting the through-hole on drawer, so that the inside and outside connection of storage space,
Eliminate drawer internal and external pressure difference, solve the problems, such as installation electrolysis deoxygenation component and caused by drawer be difficult to open.It is convenient for
User opens storage drawer 100 more laborsavingly, improves user experience.
