Automatic vending machine which cools products for sale. Sale of products not in an appropriate temperature state is prevented. A cooling device executes a partial cooling operation for cooling the product located on a lower side of the plurality of products stored in a product storage chamber when lower space temperature T1 inside the chamber becomes higher than upper-limit value TS.sub.u of set temperature range (S1.fwdarw.S2). Then, when the lower space temperature T1 is decreased to a lower-limit value TS.sub.L of the set temperature range, the automatic vending machine executes an entire cooling operation for cooling all the plurality of products (S3.fwdarw.S4). Furthermore, when the lower space temperature T1 becomes higher than upper-limit value TS.sub.u of the set temperature range during execution of the entire cooling operation, the automatic vending machine stops the entire cooling operation to execute the partial cooling operation (S5.fwdarw.S6).

Provided are a device (100) for self-adaptive regulation of air volume and a refrigerator (200) having the same. The regulating device (100) comprises: a drainage and air guide cavity (1), arranged on the back of a freezing chamber (201) of a refrigerator, the drainage and air guide cavity (1) comprising a funnel-shaped air collecting cavity (11) and a conical air outlet cavity (12) connected to the funnel-shaped air collecting cavity (11), an outlet of the conical air outlet cavity (12) facing a refrigerating chamber; a drainage tongue (2), provided in the conical air outlet cavity (12) so as to create a first outlet duct (122) and a second outlet duct (123) within the conical air outlet cavity (12), an inlet (20a) of the first outlet duct (122) being located on an extension line of a left side wall (113) of the funnel-shaped air collecting cavity (11) and an inlet (21a) of the second outlet duct (123) being located on an extension line of a right side wall (112) of the funnel-shaped air collecting cavity (11); and a fan (3) arranged inside of the funnel-shaped air collecting cavity (11). By means of rotation of the fan (3), cold air is conveyed through the first outlet duct (122) and the second outlet duct (123) and into a refrigerating chamber (202) under the guide of the left side wall (113) or right side wall (112) of the funnel-shaped air collecting cavity (11).

Disclosed herein is a refrigerator. The refrigerator includes a refrigerating compartment that is divided into a refrigerating section formed on an upper side thereof and an alternate temperature section formed on a lower side thereof, a cold air supply unit that includes a cold air flow path formed on a rear side of the refrigerating compartment and a refrigerating compartment circulation fan for allowing cold air of the cold air flow path to flow, and a control unit that controls the refrigerating compartment circulation fan. Here, the control unit cools the refrigerating section by turning on the refrigerating compartment circulation fan, and causes deflection of the cold air of the cold air flow path to cool the alternate temperature section by turning off the refrigerating compartment circulation fan.

A cell (1) for storing a set (2) of products (20) includes ventilation means (4) for creating a rear-to-front air flow (A) circulating in the housing (14) and at least one first sealing device (5 or 6) having a first flexible sealing element (50 or 60) that is inflatable in relation to one of the walls (10, 11, 12) of the cell and towards the inside of the housing (14) under the effect of an air pressure which is generated in the housing (14) by said air flow. The first sealing device (5 or 6) has at least one second sealing element (52 or 62) that can be actuated between an inactive configuration and an active configuration in which it exerts a mechanical pressure on part of the first flexible sealing element (50 or 60).

A system for blast-freezing items includes a plurality of cells arranged side-by-side, each cell including a housing with a bay space, a plenum, a front air passage, a rear air passage, and a fan. The fan is positioned in the plenum and configured to circulate air through the bay space. Each cell also includes a plurality of channels to separate pathways of air to segments of the bay space. The system also includes a plurality of crane rails extending between rows of cells and at least one crane capable of traveling along the plurality of crane rails to load or unload each of the plurality of cells.

A refrigerator has a flow path structure formed by a heat-exchanger. The refrigerator includes storage compartments, and a cool air supplying unit provided at a rear of the storage compartments to supply cool air at the storage compartments, and the cool air supplying unit includes a heat-exchanger to divide a flow path at which cool air is provided to flow along the cool air supplying unit.

An appliance having a fresh food storage compartment and a freezer compartment. The appliance includes a forced air coil system disposed between the fresh food storage compartment and the freezer compartment and is configured to selectively provide cooling to one or both of the at least one fresh food storage compartment and the at least one freezer compartment. The forced air coil system includes an evaporator fan configured to provide cooling to the food storage compartment, the freezer compartment, or both.

A refrigerator includes a storage chamber, an evaporator configured to cool the storage chamber, and an air passage through which cold air generated by the evaporator flows. The air passage includes a blower fan configured to blow the cold air to the storage chamber, and a trap part in which warm air generated by a defrosting operation stays, such that warm air generated by the defrosting operation is prevented from being introduced into the inner space of the refrigerator through the air passage. The refrigerator reduces the defrosting operation time, efficiently prevents increase of the inner temperature of the refrigerator due to warm air during the defrosting operation, reduces a temperature difference in inner temperature of the refrigerator, and prevents food stored in the refrigerator from being rotten due to a temperature change.
