Claims (3)
1. An energy-saving scale-preventing cleaning method for an electric water heater, the electric water heater comprises a shell (1) and an inner container (2), the inner wall of the inner container (2) consists of a middle cylindrical smooth section and arc sections at two ends, wherein the middle cylindrical smooth section of the inner wall of the inner container (2) is provided with a textured wire, and the outer wall of the inner container is provided with an electric heater (22) in a pressing close manner, and the energy-saving scale-preventing cleaning method is characterized in that: the inner container (2) is internally provided with flexible material scraping blades (7) which can rotate and lift along the inner wall to scrape the scale on the inner wall in a physical contact way, at least two groups of scraping blades (7) which can rotate and lift are arranged in parallel along the height direction of the inner container (2) to synchronously clean the inside, wherein a rotating motor (4) arranged at the top end of the inner container (2) is used for driving a rotating shaft (5) in the inner container (2) to rotate, the scraping blades (7) are elastically connected on a horizontal connecting rod (6) on the rotating shaft (5) in a central symmetry way, the rotating shaft (5) drives a plurality of groups of scraping blades (7) to synchronously rotate, a threaded rod (19) is driven by a positive and negative motor (17) to rotate in a threaded sleeve (16) to feed and drag a steel wire rope (15) connected to the top end of the rotating motor (4) on the left side of an inner container in the shell (1), and then the rotating shaft (5) and the scraping blades (7) below the rotating shaft are driven to synchronously lift; the specific cleaning steps are as follows:
s1, when the scraping blade (7) moves to the middle cylindrical smooth section on the inner wall of the liner (2), the scraping blade (7) is tightly attached to the inner wall and rotationally scrapes the inner wall by means of the elastic force applied to the scraping blade (7) by the connecting rod, the friction force between the scraping blade (7) and the inner wall is increased by the thread on the scraping blade, the heating area of the inner wall of the liner can be increased by the thread matched with the inner wall on the inner wall, and the daily heating efficiency is improved;
s2, when the scraping blade (7) moves upwards to the arc section close to the head of the upper end of the inner container, the spring on the scraping blade (7) is slowly compressed, the distance between the scraping blade and the connecting rod and the rotating shaft (5) is gradually reduced, and the circular chamfer design of the scraping blade ensures that the upper end of the scraping blade can smoothly slide into the arc section of the inner wall of the inner container, and the compressed spring ensures that the scraping blade can enter the inner wall of the arc section and simultaneously can ensure that the scraping blade (7) is tightly attached to the arc surface of the inner wall of the inner container, so that the scraping effect is ensured; in the process, the flexible design of the scraping piece (7) is matched with the elastic connection of the connecting rod (6), so that the attaching degree of the scraping piece and the inner wall of the inner container is further increased, and the scraping effect is ensured;
s3, when the scraper (7) moves downwards to the arc section close to the lower end head of the inner container (2), the same cleaning action as the step S2 is executed, and simultaneously, the crushing action of the scale flakes is executed through a conical crushing shaft arranged at the bottom of the rotating shaft (5);
s4, according to the cleaning effect, repeating the steps S1-S3;
in the whole cleaning process of the steps S1-S3, the water inlet pipe (20) of the inner container (2) is kept in an open water flow introduction state in the whole process, and the scale is rinsed in real time and simultaneously subjected to surface real-time wetting treatment.
2. The energy-saving scale prevention cleaning method for an electric water heater according to claim 1, characterized in that: and sealing treatment is carried out when the rotating shaft (5) penetrates through the top of the inner wall of the inner container (2).
3. The energy-saving type scale prevention cleaning method for an electric water heater according to claim 2, characterized in that: when the steel wire rope (15) drags the rotating motor (4) to lift, the vertical guiding and the elastic buffering are carried out by the aid of the fixed guide rail (23) sleeved with the spring (25).
