Instant electromagnetic heating water pipe

Abstract

The invention discloses an instant electromagnetic heating water pipe, and relates to the technical field of electromagnetic heating. The instant electromagnetic heating water pipe comprises a metal core pipe 1 and a plurality of electromagnetic induction coils 3 laid on the wall of the core pipe, wherein the electromagnetic induction coils are electrically connected with a high-frequency current generator. The instant electromagnetic heating water pipe is characterized in that the metal core pipe 1 is provided with a metal sleeve 2 which is of a sandwich structure, and the metal sleeve consists of an inner pipe 15 and an outer pipe 14. The electromagnetic induction coils 3 are positioned between the core pipe 1 and the sleeve 2, a water inlet 7 is arranged at one end of the sleeve 2, the other end of the sleeve 2 is communicated with one end of the core pipe through a communicating pipe 6, and a water outlet 8 is arranged at the other end of the core pipe. The instant electromagnetic heating water pipe has the advantages that the electromagnetic induction coils in parallel connection are parallelly arranged on one side or a plurality of sides of the core pipe and are uniformly and rapidly heated along the length direction of the core pipe, the sleeve externally wraps the core pipe, heat generated by the electromagnetic induction coils is absorbed by the inner pipe and the outer pipe and is not lost, heat efficiency is high, and the instant electromagnetic heating water pipe is safe in use and free from external radiation hazards by the aid of an insulating layer and a shielding layer.

Description

Technical field: [0001] The invention relates to the technical field of electromagnetic heating, in particular to an instant water pipe for electromagnetic heating. Background technique: [0002] In the prior art, products similar to the present invention have instant hot water faucets, but instead of electromagnetic heating, resistance wire heating is used. Theory and practice have proved that the thermal efficiency of resistance wire heating is lower than that of electromagnetic heating. The widely used induction cooker is a cooking utensil using electromagnetic heating, which requires a cooling fan to dissipate heat, which wastes some heat and reduces thermal efficiency. Invention content: [0003] The object of the present invention is to provide an instant heating electromagnetic heating water pipe, through which water can be turned into temperature-adjustable hot water, which is easy to use and has high thermal efficiency. [0004] The present invention is implement...
