FIELD: aqua vending machines.
SUBSTANCE: inventions relate to aqua vending machines, i. e. to water vending machines by means of automatically controlled dispensing of water into the container of the water buyer. Thermostating is carried out using two simultaneously carried out processes of heating the air inside the body: controlled heating of the air by means of on-off control of the operation of the electric heater and the process of unregulated heating of this air by transferring thermal energy to this air from the water in this tank through the wall of this tank, made of non-thermo-insulated metal, by continuous circular blowing of this aquareservoir with the help of a continuously operating fan. The thermostat contains a body thermal insulation, an electric heater for heating the air inside the body and a fan. The water tank is made of metal without thermal insulation of this metal and is installed in the lower part of the body at a distance from the bottom with the formation of lower horizontal and side vertical air ducts, providing the possibility of circular airflow of the water tank by the specified fan. The electric heater is made with the possibility of its on-off regulation based on feedback signals from a temperature sensor installed in the housing above the water reservoir.
EFFECT: use of three sources of thermal energy, one of which is automatically controlled by a feedback signal from a temperature sensor, and two are unregulated sources, which include drinking water, which is always in the tank.
