Abstract: A refrigeration system for a wine cooler comprises a compressor; a condenser; an ice maker evaporator; a refrigerating chamber evaporator; a first capillary pipe; a second capillary pipe; a first solenoid valve; a second solenoid valve; a first three-way pipe having an inlet end and two outlet ends. The condenser communicates with an outlet end of the compressor and an inlet end of the first three-way pipe, and the two outlet ends of the first three-way pipe respectively communicate with the first solenoid valve and the second solenoid valve forming two passages: a first passage and a second passage. Functions of the wine cooler can be realized without using a high-power compressor, and the cost and energy consumption can be reduced. A wine cooler using the refrigeration system is also disclosed.

Abstract: The present disclosure relates to a portable power distribution box that is capable powering more than five (5) and at least eight (8) items (in this embodiment of the invention) while complying with UL and OSHA safety regulations.

Abstract: A multiduty cooking appliance comprises a heating base, a cooker body, a heating head, a first electric heating device, and a second electric heating device, the cooker body encloses a cooking chamber. The first electric heating device and the second electric heating device are independent of each other. The bottom of the cooker body is placed on the heating base, the cooking chamber is disposed on top of the first electric heating device and the first electric heating device is capable of heating the cooking chamber. The heating head is placed on the top of the cooker body and covers the cooking chamber, and the second electric heating device inside the heating head is capable of heating the cooking chamber. The heating base, the cooker body and the heating head can be combined to form multiple usage modes. The heating base can be used independently as an induction cooker or an electric cooker, so the cooking appliance can be used in a wide range.
