DIRECT-FLOW WATER HEATER Russian patent published in 2008 - IPC F24H9/20 F24H1/20 

FIELD: heating.

SUBSTANCE: invention relates to power engineering and can be used in direct-flow water heaters. In a direct-flow heater with a heating module, which contains at least, one heating device, with a rotary master element for the preliminary selection of the power of heating, with at least, one stationary electric switching system, and with linearly moving depending on the flow of water to the link gear mechanism for an effect on the switching system, the link gear mechanism is rotary and is connected to the master element. The switching system, having only one switching element for each heating device switched on is provided, the link gear is effected in such a manner that only by way of a task the angle of rotation of the link gear mechanism relative to the switching system it is possible to preliminarily set the desired value of the power of heating and to power on this power by way of moving the link gear mechanism. With such implementation the heater has a minimum quantity of micro-switches and there is an opportunity to exploit it at choice or with in step-by-step controlled output or with a continuous preliminary selection of the power of heating.

EFFECT: creation of a direct-flow water heater with the possibility to exploit it at choice or with in step-by-step controlled output or with a continuous preliminary selection of the power of heating.
