DEVICE FOR MAINTAINING PRESET TEMPERATURE Russian patent published in 2019 - IPC F25D3/08 B65D81/38 A63B47/00 

FIELD: sports.

SUBSTANCE: in auxiliary sports equipment intended for storage and delivery to mini-golf balls of preset temperature balls for sporting action, which influences elastic characteristics of balls. Device for maintaining the specified temperature, made in the form of a portable container, comprises a body with thermal insulation, wherein the housing cavity is divided by partitions into a cooling chamber and cells with thermostatically controlled objects, valves, thermal sensors, heating elements, control unit and power supply, in said chamber there is a coolant, on the partition between the cooling chamber and the cells there are fans installed, which provide air circulation between the above chamber and cells through the inlet and outlet air channels with valves, in the lower part of each cell there is a heating element, above which a flat mesh element is fixed, on which a thermostatically controlled object is placed, wherein each cell comprises a temperature sensor and is sealed on the outer side of the housing by an impermeable detachable barrier element, and the heating elements, thermal sensors and fans are connected to the control unit. Flat mesh elements are arranged in cells with slope to housing outer side. Control unit comprises temperature setting unit, switches, indication unit and programmable microprocessor, first data inputs of which are connected to outputs of temperature setting unit, and second information inputs to outputs of first switch, which inputs are connected to outputs of temperature sensors, wherein inputs of the indication unit are connected to information outputs of the programmable microprocessor, control outputs of which are connected to inputs of the second switch, corresponding outputs of which are connected to control inputs of fans and heating elements. Thermostated objects are miniature golf balls. Cells with thermostatically controlled objects are detachable so that they can be removed from the housing and returned to the initial position. Impermeable removable barrier element is made in form of thermally insulated plug inserted into cell inlet hole. Dry ice is used as coolant.

EFFECT: expansion of functional and operational capabilities due to possibility of setting and controlling temperature of balls distributed in separate cells, which allows to achieve the best result at competitions.
