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 a product for purchase by a customer is disclosed. The merchandiser includes a housing defining a cavity; a door coupled to the housing; a platform located in the cavity for holding the product; a load sensor structured to determine a weight of the product; and a controller coupled to the load sensor. The controller is structured to unlock the door based on a validation of payment information of the customer, and determine a weight of product removed during a transaction for the product based on a value regarding the weight of the product removed during the transaction being substantially constant for a preset amount of time.

A photocatalyst sterilization device includes a housing, wherein the housing includes a first receiving chamber and a second receiving chamber that are in communication with each other, the first receiving chamber receives a photocatalyst layer and a light source assembly configured to irradiate the photocatalyst layer, the second receiving chamber receives an axial-flow fan; and an air inlet and an air outlet are defined in the same surface of the housing, one of the air inlet and the air outlet is corresponded to the first receiving chamber in position, the other one of the air inlet and the air outlet is corresponded to the second receiving chamber in position, and a direction in which the axial-flow fan suctions air via the air inlet is parallel to a direction of irradiation of the light source assembly.

A refrigerator includes a deodorizer installed on an upper surface of a storage compartment. The deodorizer includes a housing in which a flow path is provided, a suction port provided on a lower surface of the housing to suck air, a discharge port provided in the front of the suction port to discharge air, a photocatalytic deodorizing filter disposed at an inner side of the suction port, and a filter light source configured to irradiate light to the photocatalytic deodorizing filter, the flow path is configured to guide air from a rear lower side where the suction port is positioned to a front lower side where the discharge port is positioned, and the filter light source is disposed above the photocatalytic deodorizing filter to face the photocatalytic deodorizing filter in a state of being spaced apart from each other, and positioned above air passing through the flow path.

Example systems have a defrost system that can receive a first RF signal at a first frequency to defrost a load. An air treatment device can receive a second RF signal at a second frequency and perform an air treatment process. An RF signal source has a power output, and a switching arrangement selectively electrically connects the defrost system and the first air treatment device to the power output of the RF signal source. A controller can electrically connect one of the defrost system and the first air treatment device to the power output of the RF signal source. When the defrost system is electrically connected, the RF signal source outputs the first RF signal at the first frequency, and when the first air treatment device is electrically connected, the RF signal source outputs the second RF signal at the second frequency.

A refrigerator according to an embodiment of the present invention includes a sterilizing device, wherein the sterilizing device includes a light source assembly which emits visible rays, and a photocatalytic filter which reacts with the visible rays, and the light source assembly is disposed to be inclined at a predetermined angle with respect to a horizontal line equally dividing the photocatalytic filter in a case.

Devices, methods, and systems for disinfection with light are disclosed. In some examples, a lighting source is operable to provide light at wavelength range of about 380 nm-420 nm with an irradiance and/or dosage sufficient for disinfection. One or more sensors and a control system may be used to control operation of the lighting source, such as by adjusting the lighting source in response to various inputs.

Ultraviolet radiation is directed within an area. The storage area is scanned and monitored for the presence of biological activity within designated zones. Once biological activity is identified, ultraviolet radiation is directed to sterilize and disinfect designated zones within the storage area.

Ultraviolet radiation is directed within an area. Items located within the area and/or one or more conditions of the area are monitored over a period of time. Based on the monitoring, ultraviolet radiation sources are controlled by adjusting a direction, an intensity, a pattern, and/or a spectral power of the ultraviolet radiation generated by the ultraviolet radiation source. Adjustments to the ultraviolet radiation source(s) can correspond to one of a plurality of selectable operating configurations including a storage life preservation operating configuration, a disinfection operating configuration, and an ethylene decomposition operating configuration.

A merchandiser for storing a product for purchase by a customer is disclosed. The merchandiser includes a housing defining a cavity; a door coupled to the housing; a platform located in the cavity for holding the product; a load cell structured to measure a mass of the product; and a controller communicably coupled to the load cell. The controller is structured to unlock the door based on a validation of payment information of the customer, determine a weight of product removed during a transaction for the product, determine a type of the product removed from the ice merchandiser based on the determined weight, and determine an amount of currency required for the transaction for the product based on the determined type of product removed.
