Steam generating and heating device

Abstract

The invention provides a steam generating and heating device. A water inlet, which can be connected to a water tank, is arranged at the bottom surface of a shell; a steam outlet is arranged near to the top surface of the shell; a spiral channel is arranged in the shell, and two ends of the channel are respectively connected with the water inlet and the steam outlet; a vaporization slot is arranged between the channel and the water inlet in the shell; and the steam generating and heating device further comprises a heating pipe which is arranged in the shell, and two ends of the heating pipe respectively extends out of the shell to connect with a power supply, so that water flowing in the shell can be heated by the heating pipe so as to generate steam, thereby forming the steam generating and heating device which can adopts the natural law to prevent steam from flowing back due to back pressure to influence the smoothness of water entering and air leaving.

Description

technical field [0001] The invention relates to a steam generating heating device, in particular to a steam generating heating device which can prevent the steam from backflow due to back pressure by using natural law. Background technique [0002] The existing steam generating device mainly uses a heating device to heat water to generate steam to provide working devices such as steam irons, and the existing steam generating device mainly includes a pipeline connected to the water tank, and is provided with a The heater is used to heat the water in the pipeline to vaporize to generate steam, and then use the pipeline to transmit the steam to the working device for use. [0003] However, when the water in the pipeline is heated to form steam, a back pressure will be formed, and the back pressure will cause the steam to flow back along the pipeline to the water tank, which will affect the continuity of the water supply of the existing steam generating device and affect In ord...

Problems solved by technology

[0003] However, when the water in the pipeline is heated to form steam, a back pressure will be formed, and the back pressure will cause the steam to flow back along the pipeline to the water tank, which will affect the continuity of the water supply of the existing steam generating device and affect In order to provide the smoothness of steam, therefore, most of the existing steam generating devices will be equipped with a pump for forced water supply to maintain smooth water supply and steam generation, but this will increase the overall installation cost of the existing steam generating device

[0004] In addition, the existing heater only heats a part of the pipeline, and when the steam passes through the position corresponding to the heater in the pipeline, its temperature will drop because it cannot be continuously heated, so it is easy to be sent to the working device immediately. Water droplets are formed due to the temperature drop, which cannot provide high-temperature steam with sufficient temperature for the working device, so it will affect the working efficiency of the working device
