An internal air adjustment device (30) includes an internal-side passage (70) and an internal-side treatment unit (152). The internal-side separator (61) in the internal-side passage (70) separates return air from internal air. The composition of the return air differs from the composition of the internal air. The internal-side passage (70) supplies the return air into a storage (1). The internal-side treatment unit (152) decomposes ethylene in air that flows in the internal-side passage (70). Therefore, the concentration of ethylene of the return air is lower than the concentration of ethylene of the internal air.

A merchandiser for storing a product for purchase by a customer is disclosed. The merchandiser includes a housing that defines a cavity for storing the product and a controller for facilitating a transaction for the product at the merchandiser. The controller is configured to: receive an input to initiate a transaction for the product, the input including a type and an amount of product to be purchased; unlock a door of the merchandiser to enable a removal of the product based on receiving the input; determine a completion of the transaction based on the door being in a close position for more than a preset amount of time; and charge the customer for the type and amount of product based on the completion of the transaction.

A deodorization module includes a housing having a bar securing member and a substrate securing member, and formed of a reflective material, wherein each of the bar securing member and the substrate securing member protrudes inward from an inner side surface of the housing and has a groove. A photocatalyst bar is disposed such that air introduced into the housing passes through the photocatalyst bar. A light source module including a light source substrate and an ultraviolet (UV) light source is disposed on a first surface of the light source substrate, wherein the light source module is configured to emit light toward the photocatalyst bar. An external guide protrudes outward around an outer periphery of the housing.

An air purification module comprises a housing having an interior space provided with an air inlet and an air outlet, and an axial type blowing fan, mounted in the housing, for moving air from the air inlet to the air outlet. The air purification module further includes an air purifying unit, provided on a flow path of the air, for purifying the air and a guide for reducing the flow rate of the air between the blowing fan and the air purifying unit. The air purifying unit includes a filter provided between the blowing fan and the air outlet and a light source unit for providing light to the filter.

A merchandiser for storing at least one product for purchase by a customer is provided. The merchandiser includes: a housing defining a cavity configured to receive the at least one product; an opening defined by the housing, the opening providing access to the cavity; and a door coupled to the housing and movable between a first position and a second position. The door substantially covers the opening in the first position and the door is positioned away from the opening in the second position such that the cavity is accessible. The merchandiser further includes a control system operable in a plurality of modes including at least a run mode and a setup mode. In the run mode, purchase of the at least one product is permitted. In the setup mode, one or more run mode provisions that control operation of the merchandiser in the run mode are received.

A deodorization module including a housing having a suction port and a discharge port formed therein, a fan disposed between the suction port and the discharge port, a photocatalytic filter disposed between the suction port and the fan, a light source module including a substrate and an ultraviolet light source and configured to irradiate the photocatalytic filter with ultraviolet light, and an ion generator disposed between the fan and the discharge port.

A refrigerator includes a storage compartment and an air sanitation device mounted on a top wall of the storage compartment. The air sanitation device includes: a housing having an upper wall, a lower wall, and a peripheral wall connecting the upper wall to the lower wall; an air channel disposed in the housing and has an air inlet and an air outlet; a fan disposed in the air channel to force air to enter the air channel from the air inlet and leave the air channel from the air outlet; and an air detection device and/or an air purification device disposed in the air channel. The air outlet is disposed on the peripheral wall, and the air channel is configured in such a way that the air is discharged out of the air outlet obliquely downward.

An aseptic ice making system includes an ice making system to receive water from a water supply. The ice making system includes an ice producing subsystem to produce ice and a positive air pressure subsystem to maintain a positive air pressure environment within the ice making system.

A merchandiser for storing refrigerated product for purchase by a customer is provided. The merchandiser includes a housing defining a cavity; an opening defined by the housing, the opening providing access to the cavity; a door coupled to the housing and movable between a first position and a second position, wherein the door covers the opening in the first position and the door is positioned away from the opening in the second position such that the cavity is accessible; a lock coupled to the door, the lock actuable between a locked position and an unlocked position, wherein the lock is configured to lock the door in the first position in the locked position; and a controller coupled to the lock, the controller configured to actuate the lock to the unlocked position in response to receiving an unlock signal from a remote device.

A deodorizing apparatus including: a base, in which a suction port and a discharge port are disposed; a cover coupled to the base; a suction fan fixed to the base so as to suction air through the suction port; a first fixing member disposed between the suction port and the discharge port so as to support a filter; a light emitting module including a light emitting diode; and a second fixing member for supporting the light emitting module. The first fixing member includes a first body part for spacing the filter apart from the base.
