Automatic cleaning machine for swimming pool

Abstract

The invention relates to a swimming pool automatic-washing machine, which is formed by a power control box, a water-discharge device, a filter, a frame cover, a motor, a bracket, a cleaning belt, and a frame. Wherein, the floating material can be polyphenyl foam plastic; the cleaning belt can be modified PVC material as soft polyvinyl chlorideto apply large temperature range. It has the advantages that: 1, the new water-proof structure can prevent watering the motor, each transmission elements uses non-oil sheath structure, and service life can be above 2000 hours; 2, the direct current motor uses new material which can operate more than 1600 hours; 3, the circuit of control power and the wire distribution technique are modified to reach the Europe organism safety standard; 4, the cleaning ability is significantly improved; 5, it uses floating material to make the whole machine be able dipped in water without changing working property.

Description

(1) Technical field: [0001] The invention relates to a cleaning device, in particular to an automatic swimming pool cleaning machine. (two) background technology: [0002] At present, for swimming pool cleaning equipment, my country has a test prototype imported from Europe. The basic structure, design ideas, and working principle of the machine have taken shape, but there are still many problems. The latest certification requirements for the existing problems can be summarized as follows: 1. The sealing performance of the waterproof casing of the motor is poor. During the underwater operation, water leakage and water seepage will occur, which will cause a short circuit of the motor and burn the motor; [0003] 2. The carbon brush used in the DC motor wears too fast, so that the continuous working time of the whole machine is less than 500 hours, which is far from reaching the designed life; There are relatively obvious defects, so that the whole machine needs to be repaired...

Problems solved by technology

[0002] At present, for swimming pool cleaning equipment, my country has a test prototype imported from Europe. The basic structure, design ideas, and working principle of the machine have taken shape, but there are still many problems. The latest certification requirements for the existing problems can be summarized as follows: 1. The sealing performance of the waterproof casing of the motor is poor. During the underwater operation, water leakage and water seepage will occur, which will cause a short circuit of the motor and burn the motor;

[0003] 2. The carbon brush used in the DC motor wears too fast, so that the continuous working time of the whole machine is less than 500 hours, which is far from reaching the designed life; There are relatively obvious defects, so that the whole machine needs to be repaired and replaced frequently in order to maintain the normal operation of the whole machine; 4. The toothed belt used in this machine will break or break after more than 200 hours of continuous work. Elongation; 5. The power supply part and technical process design used in the control system of the machine are outdated, and it is difficult to guarantee the safety and reliability of the AC power supply, which does not meet the latest certification of the European Union for civilian household appliances; 6. The buoyancy material used in the machine, the material selection Inappropriate, the buoyancy index changes greatly, which cannot guarantee the good operation of the machine

In short, the test prototype has not reached the various technical indicators required in the initial design, and the safety, reliability, and applicability cannot be effectively guaranteed, and it has not yet reached the practical stage of production and sales.
