Description

Technical Field

[0002] With the development of society and the improvement of people's living standards, liquid heating equipment such as water heaters and water dispensers have gradually entered people's lives. Instant electric heaters have the advantages of instantly heating liquids and providing hot water without waiting. They are widely used in household appliances such as electric kettles and coffee capsule machines, and are deeply loved by consumers.

[0003] Conventional instant electric heaters heat the liquid by laying a heating wire and attaching the heating wire to the outside of a flow cavity or a flow channel. When the heating wire is working, it heats the flow cavity or the flow channel, and the heat is heated by the convection of the flow cavity or the flow channel through heat transfer, thereby heating the liquid. Alternatively, the heating wire is directly set in the flow cavity or the flow channel, so that the heat of the heating wire directly heats the liquid in the flow cavity or the flow channel, thereby heating the liquid. The problem is that when the instant electric heater with the above structure is working, the liquid flows continuously in the flow cavity or the flow channel. Due to the length limitation of the flow cavity or the flow channel, the liquid cannot be completely heat exchanged by the heating wire, that is, it is discharged from the instant electric heater. The heat exchange efficiency of the instant electric heater for the liquid is low, the temperature of the liquid discharged from the instant electric heater is low, the heat exchange effect of the instant electric heater for the liquid is poor, consumers cannot obtain liquid of the right temperature, and the consumer experience is poor. In addition, in order to improve the heat exchange effect of the instant electric heater, a high-power heating wire needs to be used, which increases the manufacturing cost and the use cost of the instant electric heater.

[0004] Therefore, further improvement is needed. Utility Model Content
