Description

Technical Field

[0001] The utility model belongs to the technical field of electric heating equipment, and particularly relates to an instant heater with good heat exchange effect. Background Art

[0002] With the continuous development of society and the continuous improvement of living standards, liquid heating appliances such as water heaters, water dispensers, and coffee machines have gradually entered people's living and working environments. The liquid heating appliances sold on the market are equipped with instant heaters to heat the liquid in their containers. The instant heater has the advantages of instant heating of the liquid and obtaining hot water without waiting, and is deeply loved by people.

[0003] For a conventional instant heater, heating elements such as heating wires or thick film heaters are laid on the outer side of the flow cavity or flow channel. When the heating element works, it heats the outer side of the flow cavity or flow channel, and the heat is transferred to the liquid in the flow cavity or flow channel through heat transfer to heat the liquid, so as to achieve heating of the liquid. Or the heating element such as a heating tube is directly arranged in the flow cavity or flow channel, and the heat of the heating element directly heats the liquid in the flow cavity or flow channel to achieve heating of the liquid. The problem is that for the instant heater with the above structure, when it works, the liquid continuously enters and exits the flow cavity or flow channel. Limited by the length of the flow cavity or flow channel, the liquid in the flow cavity or flow channel is output outside the flow cavity or flow channel before being fully heat exchanged, resulting in a low temperature of the heated liquid. The heat exchange effect of the instant heater on the liquid is poor, which cannot meet the use requirements of consumers. Moreover, in order to improve the heat exchange effect of the instant heater, heating elements with high power need to be used, which increases the manufacturing cost and use cost of the instant heater.

[0004] Therefore, further improvement is needed. Summary of the Utility Model
