Definitions
- the invention relates to a water heating device according to the preamble of patent claim 1 . 5
- a water heating device of the type mentioned above is known from patent document DE 20 2004 012 263 U1.
- This water heating device designed as a continuous-flow heater consists of a space filled with water, an electrical heating device provided for heating the water in the space, and power electronics arranged on the space and provided for controlling the heating device.
- said space is designed as a water-carrying pipe.
- the object of the invention is to improve a water heating device of the type mentioned at the outset.
- a water heating device with a precisely controlled cooling of the power electronics is to be created.
- a electrothermal converter for the regulated transfer of heat between the power electronics and a wall of the room that is in contact with the water, a electrothermal converter, in particular a Peltier element, is provided.
- the water heating device is characterized in that the electro-thermal converter can be used to specifically determine how much heat is to be released from the power electronics to the water. Or to put it the other way around: the cooling of the power electronics can be regulated very precisely according to the invention.
- FIG. 1 in section the water heater according to the invention.
- the water heating device shown in the single figure consists, in a manner known per se, of a space 1 filled with water, an electrical heating device 2 provided for heating the water in space 1, and an electrical heating device 2 arranged on space 1 for controlling the heating device 2 provided power electronics 3 .
- Said space 1 is preferably designed either as a hot water storage tank for a heating system or as a flow space (particularly a pipe) for an electric flow heater.
- What is essential for the water heating device according to the invention is that for the controlled transfer of heat between the power electronics 3 and a wall 1 that is in contact with the water and is preferably made of metal. 1 of the room 1, an electrothermal converter 4 is provided. Expressed in terms of the method, it is provided that the heat generated at the power electronics 3 is transferred to the water in the room 1 with the aid of the electro-thermal converter 4 . Due to this stipulation, it is ultimately even possible, due to the targeted use of the waste heat, to make the power electronics 3 smaller than before.
- a current flowing through the electrothermal converter 4 f is designed to be controllable, preferably via a higher-level control device of the water heating device, in order to set the transfer of heat (i.e. in particular the actual amount of heat).
- a power supply connection 4 . 1 of the electrothermal converter 4 electrically connected to a power output terminal 3 . 1 of the power electronics 3 is connected.
- the power electronics 3 and the electrothermal converter 4 are preferably electrically connected to one another and designed so that the same current flows through them.
- the electrothermal converter 4 is also preferably made for the electrothermal converter 4 to be designed to absorb heat from the air surrounding the electrothermal converter 4 .
- the electric heating device 2 is designed as a resistance heater arranged in space 1, in particular as a heating element.
