Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of washing machines, and particularly relates to an electrolytic water system of a pulsator washing machine. BACKGROUND

[0002] There are two kinds of washing machines, namely, a pulsator washing machine and a drum washing machine. Traditional washing machines mainly rely on adding washing powder or washing liquid in washing water to achieve the cleaning effect on clothes, which inevitably causes water pollution. In recent years, an electrolytic water washing machine without an outer cylinder has appeared. An electrolytic water device is added to the washing machine. The electrolytic water device is provided with a direct current power supply for the anode and the cathode to electrolyze the washing water. The high permeability of electrolytic ion water and the decomposition and adsorption of ions on stains and dust can achieve the effect of removing stains on clothes. At the same time, active oxygen and hypochlorous acid generated by electrolytic water also have a certain sterilization effect.

[0003] However, the current electrolytic water system of the washing machine still has some problems to be further improved. The electrolytic water device of the traditional pulsator washing machine is installed on the outer cylinder of the washing machine. After a period of use, stains will be retained in the electrolytic water device. For example, the electrolytic water system of the washing machine in patent document CN116375146A. The electrolytic gap between the anode and the cathode of the electrolytic water device is generally small. The electrolytic gap is easy to be blocked by the retained stains, which will affect the electrolytic water efficiency. On the other hand, if the electrolytic gap between the two electrolytic plates is too large, the electrolytic current will be small, which will reduce the electrolytic efficiency.

[0004] Another electrolytic water system of a washing machine is described in patent document CN116005416A. The pulsator and the rotating inner cylinder are used as the anode and the cathode of electrolytic water, respectively. The pulsator is electrically connected to the direct current power supply through the pulsator power shaft, the inner cylinder drive shaft, the bearing with a seat, and the iron strap in sequence. However, when the washing machine is running, the balls inside the bearing with a seat are constantly rotating. If the electrolytic water current is conducted to the pulsator through the bearing, electric sparks will be generated in the process of rolling of the bearing balls, which will damage the bearing and seriously affect the normal service life of the bearing. Therefore, it is necessary to further improve and perfect the electrolytic water system of the pulsator washing machine. SUMMARY

[0005] In view of the above problems, the present application provides an electrolytic water system of a pulsator washing machine, which is mainly used to solve the problem of stain retention between the anode and the cathode of the electrolytic water device of the pulsator washing machine, and the problem of abnormal wear of the bearing affecting its service life.

[0006] In order to achieve the above purpose, the present application adopts the following technical scheme:

[0007] A pulsator washing machine electrolytic water system, comprising a fixed shell of the washing machine and a rotating inner drum for containing washing water, the rotating inner drum is rotatably arranged inside the fixed shell, and a washing pulsator is rotatably arranged in the middle of the bottom of the rotating inner drum.

[0008] A conductive ring is coaxially arranged outside the washing pulsator, and arc-shaped electrolytic electrodes one and two are respectively arranged on the left and right sides of the periphery of the conductive ring in a face-to-face manner, both of the electrolytic electrodes are fixedly connected to the inner side wall of the rotating inner drum, and the two electrolytic electrodes cooperatively form a non-closed surrounding of the conductive ring, an isolation gap is arranged between the two ends of the two electrolytic electrodes, and an electrolysis gap is arranged between the two electrolytic electrodes and the conductive ring.

[0010] Preferably, the direct current power supply adopts an AC / DC power supply module for converting alternating voltage into safe direct current voltage, and the two output ends of the direct current power supply are electrically connected to the two brush contacts through electric wire one and electric wire two respectively. The input end of the direct current power supply is connected to 220V alternating voltage, and the output voltage between the positive and negative poles of the output end of the direct current power supply is a safe voltage of 42V or below, further preferably a human body safe voltage of 36V or below, and more preferably a human body safe voltage of 24V or below which can be continuously contacted, to prevent electric shock accidents.

[0011] Preferably, the two ring-shaped contacts are fixedly sleeved on the outer side wall of the rotating inner drum from top to bottom, the two ring-shaped contacts are electrically connected to the two electrolytic electrodes through lead wire one and lead wire two respectively, the two brush contacts are fixedly arranged on the upper end of the rotating rod from top to bottom, and the two ring-shaped contacts and the two brush contacts are insulated from each other.

[0012] Preferably, a torsion lever for driving the rotating rod to rotate is arranged at the lower end of the rotating rod, a driving motor for driving the torsion lever to rotate is arranged outside the fixed shell, and a return spring for driving the rotating rod to return to the original position is arranged between the rotating rod and the fixed shell.

[0013] Preferably, the conductive ring is a waistband-shaped metal ring, and the conductive ring is fixedly arranged on the outer edge of the washing pulsator.

At the same time, it also effectively solves the problems of the electrolytic water system in washing machines such as those in patent document CN116005416A, avoiding the situation where the rotating bearing is used as a conductor and is prone to sparking, causing bearing damage.

[0020] The technical solution of the present invention will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

The rotating inner drum is rotatably disposed inside the fixed outer shell, and a washing pulsator 3 is rotatably disposed at the bottom center of the rotating inner drum.

[0024] The outer side of the washing impeller is coaxially provided with a conductive ring 4, and the outer periphery of the conductive ring is respectively provided with arc-shaped electrolytic electrode one 5 and electrolytic electrode two 6, both of which are fixedly connected to the inner side wall of the rotating inner cylinder, and both of which form a non-closed surrounding of the conductive ring, and the two ends of the two electrolytic electrodes are provided with a separation gap 23, and the electrolytic gap 24 is provided between the two electrolytic electrodes and the conductive ring.

[0025] The outer side wall of the rotating inner cylinder is provided with annular contact one 7 and annular contact two 8, which are respectively electrically connected to the two electrolytic electrodes; the side wall of the fixed shell is provided with a rotating rod 9, which is rotatably connected to the fixed shell, and the upper end of the rotating rod is provided with brush contact one 10 and brush contact two 11, which are respectively electrically connected to the two annular contacts; the outer side of the rotating inner cylinder is provided with a direct current power supply 12.

[0026] The direct current power supply adopts AC220V / DC24V power module, and the two output ends of the direct current power supply are respectively connected to the two brush contacts through the wire one 13 and the wire two 14. The input end of the direct current power supply is connected to 220V alternating voltage, and the output end of the direct current power supply outputs 24V safe direct current voltage. The wire one or the wire two is also provided with a current sensor 15, which is connected to the electric control system of the washing machine for detecting and displaying the size of the electrolytic current.

[0027] The two annular contacts are fixedly sleeved on the outer side wall of the rotating inner cylinder from top to bottom, and the two annular contacts are respectively connected to the two electrolytic electrodes through the wire one 16 and the wire two 17. The two brush contacts are fixedly arranged on the upper end of the rotating rod, and the two annular contacts and the two brush contacts are insulated from each other.

[0028] The lower end of the rotating rod is provided with a torsion lever 18 for driving the rotating rod to rotate, the outer side of the fixed shell is provided with a driving motor 19 for driving the torsion lever to rotate, and the rotating rod and the fixed shell are provided with a return spring 20 for driving the rotating rod to rotate and reset.

[0029] As shown in Figures 2-3 The conductive ring is a waistband-shaped metal ring, and the conductive ring is fixedly arranged on the outer edge of the washing impeller.

[0030] When the washing machine is not used, there is no water in the rotating inner drum, and the two electrolytic electrodes fixed on the inner side of the rotating inner drum and the two electrolytic electrodes and the conductive ring of the washing impeller are not conductive to each other because there is obvious physical isolation between them; when the washing machine is used to wash clothes, the rotating inner drum contains water, and the two electrolytic electrodes and the conductive ring on the washing impeller are immersed in water, and they are conductive to each other, and with the rotation of the washing impeller, the conductive ring always acts as a conductive medium between the two electrolytic electrodes, and the electrolytic gap between the two electrolytic electrodes and the conductive ring is continuously subjected to electrolytic water reaction; at the same time, since the washing impeller is always rotating, the water flow is also passing through the electrolytic gap, and the high-speed water flow brought by the rotation of the impeller can wash away the stains and bubbles accumulated on the anode and cathode plates, so as to prevent the stains from depositing in the electrolytic gap and avoid blocking the electrolytic gap, and ensure that the electrolytic water efficiency always maintains the best state.

[0031] The technical scheme of the present application is not limited to the above specific embodiments, and many modifications and changes are obvious to those skilled in the art without departing from the scope and spirit of the described embodiments, and any technical modification made within the spirit and principles of the present application falls within the protection scope of the present application.
