Steam heating device

Abstract

The invention provides a steam heating device. The steam heating device comprises an upper cover, a lower cover and a heater body, wherein the heater body, the upper cover and the lower cover are buckled and packaged to form an upper layer channel and a lower layer channel; the upper layer channel communicates with the outside through a water inlet and a steam outlet; the heater body is provided with a baffle plate, a water vapor inlet, a steam channel port and a built-in U-shaped heating pipe; the baffle plate directly faces the water inlet to enable water flow to be dispersed, and the waterflow flows from the water vapor inlet to the lower layer channel to be fully vaporized and flows from the steam channel port to the steam outlet to be sprayed out; a water-proof heating platform witha matching temperature is arranged on one side toward the lower cover of the heater body. According to the steam heating device., the water-proof heating platform with the matching temperature is designed through improvement, and the phenomenon that the water flow is not heated due to the fact that the water flow encounters the cold area is avoided; and the steam heating area is divided into two blocks, the steam outlet channel is longer, the vaporization is more complete, the heating loss is reduced, and the steam outlet rate is improved at the same power.

Description

technical field [0001] The invention relates to the technical field of steam heating devices, in particular to a steam heating device used in a steam mop. Background technique [0002] Steam cleaning technology dissolves stubborn stains and sterilization and disinfection through high-temperature steam at 120 °C. It is widely used in sterilization, dust removal, decontamination and grease removal. Steam mop is one of the typical products that apply steam cleaning technology. . [0003] In the prior art, U-shaped heating tubes are often used for heat exchange, and the water inlet is arranged in the arc section of the U-shaped heating tube. When high-speed water flow enters the heater, the water flow will easily spread away from the U-shaped heating tube after it hits the baffle and disperses. In the cold zone, there is no heating phenomenon, which makes the heating efficiency and heat utilization rate of the whole steam heater low; and the steam outlet channel is relatively s...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, U-shaped heating tubes are mostly used for heat exchange. The water inlet is set on the arc section of the U-shaped heating tube. When the high-speed water flow enters the heater, the water flow hits the baffle and spreads away from the U-shaped heating tube. In the cold area, there is no heating phenomenon, which makes the heating efficiency and heat utilization rate of the whole steam heater lower; and the steam outlet channel is relatively short, and the steam heating is likely to be incomplete, making the use effect unsatisfactory
