Background technique

The steam generator of the prior art forms a specially designed flow passage inside the die-casting body through integral die-casting of the product, and the water enters the flow passage to form steam by heating. However, the steam pressure generated by conventional products tends to be large, and the internal structure is complicated, which complicates the processing of product molds, has a high defect rate, and has a short production cycle. The product designed by the invention replaces the traditional flow channel with a metal pipe, that is, the metal pipe and the heating pipe are combined together in the steam generator, and then die-cast into a product, which improves the performance of the product and greatly avoids the production. Various problems.

Summary of the invention

SUMMARY OF THE INVENTION The object of the present invention is to provide a steam generator which is simple in process, high in thermal efficiency, capable of achieving rapid vaporization, and having a relatively small residual steam pressure when the product is stopped.

The technical solution of the steam generator of the present invention is: a steam generator comprising a casing, and a heating body placed in the casing, adjacent to the steam flow passage of the heating body, the two ends of the steam flow passage are respectively the water inlet and The steaming port is a metal pipe, the metal pipe is arranged in a spiral shape, the heating body is also a spiral tubular shape, the steam flow channel is coated on the outside of the heating body, and spirals upward in the axial direction of the heating body, the steam flow channel and the heating The body forms a close fit.

Preferably, the heating tube and the steam flow path are radially perpendicular to the radial direction of the heating body.

Optimizedly, the metal tube is set as a stainless steel tube.

Optimizedly, the metal tube is set as a copper tube.

Optimizedly, the metal tube is set as an iron tube.

Optimizedly, the steam generator further includes a mounted temperature control switch, a temperature fuse, and a temperature sensor disposed on the housing.

Preferably, the water inlet end of the steam generator is integrated on the housing.

The steam generator steam flow channel of the technical solution is set as a metal pipe, the metal pipe is arranged in a spiral shape, the heating pipe is arranged in a spiral shape, the heating pipe is covered by the metal pipe, the heating pipe and the metal pipe are spirally oriented perpendicular to each other, and the heating pipe is Being gold The tube is covered. Since the steam flow passage is set as a metal pipe, when the product stops working, the residual steam pressure is smaller and the steaming is stopped faster; at the same time, when the product works, rapid vaporization can be realized; the product production process designed by the invention is compared with the traditional product. The simplification and the improvement of the production efficiency; the design adopted by the invention can make the heat conversion efficiency higher, and the steam effect can be better by the shape of the stainless steel pipe and the heating pipe, the design of the combination mode, and the selection of the pipe material.

The heating pipe of the technical solution is arranged in a spiral shape, and the spiraling direction of the heating pipe and the metal pipe are perpendicular to each other. This arrangement can make the contact area of the heating pipe and the metal pipe larger, and the heating effect is better.

The metal pipe of the technical solution can be set as a stainless steel pipe, a copper pipe, or an iron pipe. The specific pipe and pipe design shape and the combination with the heating pipe can be specifically set according to the cost and the required steam performance.

The technical solution also sets the installation position of the temperature control switch, the temperature control fuse and the temperature sensor. Through the selection of the temperature control switch installation position and the model number, the generator is heated to a certain temperature and then the heating is stopped to form intermittent heating, so as to ensure The steam effect meets the design requirements.

The technical scheme adopts the heat transfer and vaporization of the metal pipe. Compared with the conventional product, when the product stops working, the residual steam pressure is smaller and the steaming is stopped faster; while the product works, the rapid vaporization can be realized; the product production process phase designed by the invention Compared with the traditional products, the production efficiency is improved; the design adopted by the invention can make the heat conversion efficiency higher, and the steam effect can be better by the shape of the metal pipe and the heating pipe, the design of the combination mode, and the selection of the pipe material.
