CUPBOARD DRIER Russian patent published in 2021 - IPC F26B9/00 

FIELD: drying equipment.

SUBSTANCE: invention relates to drying equipment and can be used in household electric dryers for drying vegetable and other moisture-containing products. The cupboard drier contains a housing, removable trays for product placement, a heating element, and a control unit. The casing with thermal insulation is divided by a partition into a section in which all-metal trays are installed for conductive drying of the product, and a section in which a heating element is located. The heating element is made in the form of a thermoelectric assembly consisting of a hot loop with an air radiator, a cold loop with a condensation zone of a heat pipe and a thermoelectric Peltier module. The Peltier module is located between the hot and cold circuits. For ventilation and removal of excess moisture, there is an inlet air duct in the lower part of the case, and an outlet duct in the upper part. The evaporating zone of the heat pipe is located in the outlet channel, and the condensation zone of the heat pipe is located on the radiator of the cold loop and tightly adjoins it. The transport zone of the heat pipe, placed in thermal insulation, runs along the outer side of the side wall of the housing. The air temperature sensor is installed at the top of the ventilation duct. The thermoelectric module and the temperature sensor are connected to the control unit.

EFFECT: reducing the cost of electricity for drying vegetable and other moisture-containing products while maintaining high quality indicators of the finished product.
