Abstract

The invention relates to a heating device for liquid heating. The heating device comprises a sealing support, a heating body, a water inlet and a water outlet. The sealing support and the heating body are in sealed connection. A cavity is defined by the sealing support and the heating body. A sealing body is arranged inside the cavity. A sealing water channel with the certain capacity is defined by the sealing body and the heating body. The sealing water channel is communicated with the external world through the water inlet and the water outlet. Liquid entering the water inlet is sealed and limited inside the sealing water channel and flows out of the water outlet along the sealing water channel. According to the heating device, the starting-up preheating waiting time can be shortened, the continuous water outlet temperature is stable, and the temperature of cast aluminum does not need to be maintained by means of heating during standby; meanwhile, the problems that water outlet steam and non-continuous water outlet are caused by gasification due to the water circulating problem caused by a gap between a liquid flow pass and a stainless steel thick film heater can be avoided.

Description

technical field [0001] The invention relates to a heating device, in particular to a heating device for liquid heating. Background technique [0002] Generally, in heating appliances that require continuous hot water, the heating resistance wire is wrapped or filled with an insulating layer and embedded in cast aluminum with good thermal conductivity. At the same time, the stainless steel tube is bent to form a continuous liquid flow channel. in cast aluminum. [0003] Because the heat generated by the heating resistor cannot directly exchange heat with water, the cast aluminum needs to be heated to a certain temperature first, and the heat on the cast aluminum passes through the stainless steel tube liquid channel to generate heat exchange with water. Due to the large thermal inertia of aluminum, there will be the following problems: 1. When starting up, it takes a long time for 15 to 30 seconds (seconds) to warm up before the cast aluminum can be heated to the required te...
