Problems solved by technology

In the liquid heating unit of this structure, the liquid circulation channel is still composed of heating water pipes, and the heater is placed inside the heating water pipes. It is necessary to connect multiple sets of heating water pipes in series to increase the length of the liquid circulation channel. The overall structure is also quite clumsy.

Abstract

The invention relates to a liquid-heating unit comprising a flat heating element, a guiding plate and a meandrous liquid flowing passage. The guiding plate forms border sealing connection with one side of the flat heating element; the meandrous liquid flowing passage is formed between the guiding plate and the flat heating element; and the guiding plate is provided with a liquid inlet and a liquid outlet which are respectively communicated with a liquid inlet end and a liquid outlet end of the liquid flowing passage. The liquid-heating unit is characterized in that the liquid inlet and the liquid outlet are respectively arranged at the border part and the center part of the guiding plate, and the liquid flowing passage is spirally arranged. Compared with the prior art, the invention has the advantages that the integral size of the liquid-heating unit is not increased on a basis that the length of the liquid-heating unit is increased, and the heat-exchanging efficiency is very high.

Description

technical field [0001] The invention relates to a heating power supply, in particular to a liquid heating unit for rapidly heating liquid. Background technique [0002] In drinking fountains, water heaters and other liquid heating devices, the liquid heating unit is the most critical component. In order to reduce the time required to heat a given liquid to a given temperature, manufacturers of liquid heating devices have developed liquid heating units of different configurations. [0003] For example, the Chinese utility model patent with publication number CN 201096399 (patent number: ZL 200720177939.0) discloses a liquid heating device, which includes a tubular heating body enclosed with an inert gas and an electric heating device, and electrodes pass through both ends of the heating body Connected to the power supply, the heating body has a closed inner tube and an outer tube stacked double-layer cavity tube to form the heating body assembly. The cavity of each layer is ...
