Description

Technical Field

[0001] The utility model relates to the technical field of car washers, and particularly relates to a steam generating device of a steam car washer. Background Technique

[0002] Traditional car washing methods generally use high-pressure water jets for cleaning. The water jets are ejected at high speed from a water spray gun. This not only consumes a large amount of clean water but also generates a large amount of sewage after cleaning. For this reason, people have designed a method of generating steam by electric heating for cleaning. The high-pressure steam is transported through a steam delivery pipe to a steam spray gun, and the steam spray gun is controlled by a worker pressing the trigger switch. CN208069616U discloses a steam generating device for a steam car washer, which includes a spring-shaped metal spiral tube formed by bending and winding a metal tube into a spring shape. There is also a combustion chamber, and a circular main exhaust port is provided at the top of the combustion chamber; the spring-shaped metal spiral tube is located in the cylindrical combustion chamber, and the inner diameter of the combustion chamber is slightly larger than the spiral outer diameter of the spring-shaped metal spiral tube, and the pitch of the spring-shaped metal spiral tube is larger than the outer diameter of the tube body of the spring-shaped metal spiral tube; a circular cover member is provided at the topmost end of the central space area, and the circular cover member is located directly below the circular main exhaust port of the combustion chamber; a fuel feeding channel and an air intake channel are provided at the bottom of the combustion chamber. However, in this application, the moisture directly discharges from the exhaust port after passing through the combustion chamber, resulting in insufficient vaporization, which leads to insufficient steam volume or a large amount of water droplets in the steam. A large amount of water stains will affect the car washing effect, especially the cleaning process of materials such as genuine leather inside the car. This application is not suitable for a car washing environment with strict requirements for water vapor conditions. The Chinese patent discloses a steam generating device for a steam car washer and its steam car washer (authorized announcement number CN210554694U). This patented technology discloses a steam generating device for a steam car washer and its steam car washer. The steam generating device includes a combustion device, a combustion chamber, and a heating part. The heating part is arranged inside the combustion chamber, and also includes a steam post-treatment part. The steam post-treatment part is arranged outside the combustion chamber. The steam post-treatment part includes a steam inlet, and the steam inlet is arranged at the upper end of the combustion chamber. A steam outlet is arranged at one end of the steam post-treatment part far from the steam inlet. In this application, the moisture undergoes a large amount of preliminary vaporization process through the heating part. The function of the steam post-treatment part is to further vaporize the preliminarily vaporized water vapor, increase the steam generation amount, and further reduce the amount of water droplets in the steam. The steam post-treatment part is arranged outside the combustion chamber, effectively utilizing the waste heat of the combustion chamber and improving the heat utilization rate. This patented technology solves the problems that since the steam is continuously generated during the car washing process, a very large electric heating power and current are required to generate enough pressure steam in time. It is very difficult for ordinary car wash yards to apply for a municipal power grid connection with a large enough power and current. Therefore, if an ordinary car wash yard relies on electric heating to generate steam, the steam pressure is often low, which will affect the steam injection speed; it takes a certain amount of time to generate steam, and the continuity of the generated steam is poor, which will affect the car washing effect.

[0003] However, in the prior art, when steam is generated, since cold water is usually directly sprayed, when the weather is relatively cold and the water temperature is low, it is easy to cause damage to the inside of the combustion chamber due to rapid cooling, and it is necessary to solve the problem of preheating the water source in the steam generation and supply in the prior art. The preheated high-temperature water source can increase the steam generation efficiency and reduce the occurrence of malfunction accidents.

[0004] Therefore, those skilled in the art provide a steam generation device for a steam car washer to solve the problems raised in the above background art. Utility Model Content
