Provided is a refrigerator, including a freezer compartment, a refrigeration compartment, a drying compartment, an air intake channel, a first sealing apparatus, and a second sealing apparatus. The drying compartment is independently provided within the refrigeration compartment in a sealed manner. The drying compartment is provided with an air inlet and an air outlet. The first sealing apparatus is provided in the drying compartment and can switch between sealing an air outlet of the air intake channel and leaving the air outlet of the air intake channel open. The second sealing apparatus is provided at the air outlet and can switch between sealing the air outlet and leaving the air outlet open. Cooled air in the freezer compartment is introduced into the drying compartment and then mixed with air in the drying compartment, a rise in the temperature of the cooled air allows the relative humidity in the drying compartment to be reduced.

An ice maker and method of operation for a refrigeration appliance, the ice maker including an ice maker frame having an air inlet provided at a first end thereof. An ice tray is rotatably secured to the ice maker frame and configured to form ice pieces therein. An air handler includes an outlet diffuser having a central body defined by a first wall-and a radially spaced apart second wall, wherein a plurality of radially extending fins are disposed between the first and second walls. Each of the fins is spaced apart, one from the other, along an outer peripheral surface of the first wall. In an installed position, the outlet diffuser is disposed directly adjacent the air inlet at the first end of the ice maker frame. A method is provided for synchronizing an ice making cycle of an ice making unit and a defrost cycle of an evaporator.

In order to improve the efficiency of solidification and melting of a heat storage material in a heat storage material unit, a heat storage material covered with a coating material is accommodated in a metal accommodating container having a high thermal conductivity, and the heat storage material unit is embedded in a thermal insulation panel in such a way that the accommodating container is exposed inside a merchandise accommodating compartment, thereby enabling a surface of the heat storage material that is embedded in the thermal insulation panel also to exhibit an action equivalent to that if the accommodating container is exposed in the merchandise accommodating compartment as a heat transfer element, thereby improving the efficiency of solidification (heat storage) and melting (heat dissipation) of the heat storage material.

A deodorization module and a storage device including the deodorization module. A deodorization module includes: a housing; a suction opening formed on the lower surface of the housing to allow external air to be suctioned therethrough; a fan disposed at the suction opening to suction the air; a discharge opening for discharging the air, which has been suctioned by the fan, to the outside of the housing; a photocatalytic bar disposed between the fan and the discharge opening; and a light source module, which includes a light source substrate and an ultraviolet light source and irradiates an ultraviolet ray to the photocatalytic bar.

A refrigerator appliance includes a cabinet that defines first and second compartments. A fan assembly is configured to direct cooled air from a cooling assembly into the first and second compartments. The fan assembly includes a housing that defines an inlet, a first outlet, and a second outlet. The first outlet is in communication with the first compartment, and the second outlet is in communication with the second compartment. A fan is positioned within the housing and is configured to direct the cooled air from the inlet toward the first and second outlets. A damper assembly is configured to selectively obstruct one of the first outlet and the second outlet.

A cooling unit enabled to maintain the internal temperature for an extended period of time without an outside electrical power is described. The cooling unit uses a combination of a battery (or one or more battery backs) and one or more phase change materials (“PCM”). In addition, the cooling unit uses one or more airpaths to force cooled air over a group of PCM to maintain the PCM for the event when an external electrical power is discontinued and the power from the battery pack is also depleted. The forced air through one of more airpaths may be always used or only when the cooling unit is operated by only the battery power.

There is disclosed a shroud for a refrigerator including a blower for generating air flow; a first region arranged on the right of the blower, the first region comprising an outlet hole for a first storage chamber for exhausting cold air to the first storage chamber; a second region arranged on the left of the blower, the second region comprising an outlet hole for a second storage chamber for exhausting cold air to the second storage; a third region arranged under the blower, the third region comprising an outlet hole for the second storage chamber; and a first guide arranged between the second region and the third region, projected closer to a rotational center of the blower, to guide air flow.

A refrigeration appliance comprises a fan mounting assembly mountable to a liner of a cabinet. The fan mounting assembly comprises a bracket, a first member of a first snap coupling on the bracket for receiving a corresponding second member of the first snap coupling on an evaporator coil cover, and a mounting flange having a first member of a snap lock extending from the bracket for mounting the fan mounting assembly to the liner of the cabinet. An evaporator coil cover for mounting to the fan mounting assembly comprises a second member of the first snap coupling allowing the evaporator coil cover to be coupled to the fan mounting assembly, and a first slot. An air tower assembly mountable to the fan mounting assembly through the first slot comprises a second member of a second snap coupling and a second member of a third snap coupling.

A muffler comprising a hollow cavity enclosed by a first bottom surface, a second bottom surface and a side wall, the side wall connects the first bottom surface with the second bottom surface, an air inlet at one end of the hollow cavity and an air outlet at the other end of the hollow cavity; the cavity is divided into a plurality of chambers in an axial direction, the chambers comprise a first chamber adjacent to the first bottom surface, a second chamber adjacent to the second bottom surface and an intermediate chamber located between the first chamber and the second chamber, the air inlet is in gas communication with the intermediate chamber, and the air outlet is in gas communication with the first chamber.

The resent invention provides a refrigerator comprising: a cabinet having a storage chamber; a door for opening and closing the storage chamber; a case having a discharge port through which air is discharged to the storage chamber; an evaporator provided inside the case and for supplying cold air by means of heat exchange with air; a fan installed on the discharge port and for generating the airflow discharging to the storage chamber the air which has been heat exchanged in the evaporator; and a differential pressure sensor having a first pipe, of which one end is positioned on a part where the air is withdrawn to the fan, and a second pipe of which one end is positioned on a part where the air is discharged from the fan.
