Abstract
The utility model belongs to the technical field of heating devices, and particularly relates to a frost crack resistant heating device of an instant heating system. Two ends of a heating pipe are respectively connected with a water inlet device and a water outlet device. The water inlet device, the water outlet device and the heating pipe form a communicated pipeline. Openings are formed in the water inlet device and the water outlet device, wherein the openings enable the pipeline formed by the water inlet device, the water outlet device and the heating pipe to be communicated with the outside at two ends of the heating pipe. Elastic sealing fins are plugged on the openings to enable the pipeline which is communicated by the water inlet device, the water outlet device and the heating pipe to form sealing connection. According to the frost crack resistant heating device of the instant heating system, the elastic sealing fins can release stress produced due to the fact that water in the heating pipe is frozen. After ice-out, the elastic sealing fins can automatically reset. Not only is the problem that the heating pipe is prone to cracking after the heating pipe is frozen solved, but also the trouble of replacement of the heating pipe in post maintenance is eliminated. Besides, hidden dangers such as water leakage and electricity leakage caused by frost crack of the heating pipe are avoided. The frost crack resistant heating device of the instant heating system is suitable for occasions which need instant heating such as coffee machines, straight drink machines and intelligent closestools.
