The control panel is arranged on the outer surface of the shell, and a user can control the operation of the washing machine through the control panel.
The drain pipe 300 communicates the bottom of the dissolving chamber 210 and the washing tub 100 to enable the washing water in the washing tub 100 to be drained into the washing tub 100.
Fig. 2 is a schematic diagram of an embodiment of a bubble generation device 200 of a microbubble washing machine according to the present invention.
Referring to fig. 1 and 2, the bubble generating apparatus 200 includes a dissolving chamber 210, a water outlet pipe 220 extending from an upper portion of the dissolving chamber 210 into the dissolving chamber 210, and a bubble generator 230 disposed on the water outlet pipe 220.
A closed and hollow shell is arranged in the shell, and a dissolving cavity 210 arranged in a sealing way is formed in the shell. The dissolution chamber 210 receives external washing water, the external washing water and the air in the dissolution chamber 210, and the internal pressure of the sealed container is increased, so that the gas in the dissolution chamber 210 is dissolved in the washing water by the pressure of the air water itself.
In this embodiment, the bubble generating device 200 further includes a water inlet pipe 240 for introducing the washing water into the dissolving chamber 210, and the water inlet pipe 240 is provided with a water inlet valve 250, and the external washing water can be selectively communicated through the water inlet valve 250. The water inlet pipe 240 is connected to the upper portion of the dissolving chamber 210 to introduce the washing water into the dissolving chamber 210 from the upper portion of the dissolving chamber 210, thereby effectively preventing the washing water in the dissolving chamber 210 from flowing back.
One end of the water outlet pipe 220 positioned in the dissolving cavity 210 extends from top to bottom and is close to the bottom of the dissolving cavity 210, and the other end of the water outlet pipe 220 is communicated with the washing tub 100; the washing water in the dissolving cavity 210 is melted into the gas in the dissolving cavity 210 under the action of the self-pressure, and then enters the water outlet pipe 220 under the action of the self-pressure, and is discharged into the washing tub 100 after bubbles are generated by the bubble generator 230 on the water outlet pipe 220, so that the clothes in the washing tub 100 are washed by the micro-bubbles. Since the volume of the dissolution chamber 210 is constant, the pressure of the washing water and air in the dissolution chamber 210 is increased in the sealed container, and thus the gas in the dissolution chamber 210 is dissolved in the washing water under the action of the self-pressure. Meanwhile, the water outlet pipe 220 extends into the dissolving cavity 210 from the upper end of the dissolving cavity 210, and the inlet of the water outlet pipe 220 is close to the bottom end of the dissolving cavity 210, so that the washing water in the dissolving cavity 210 can enter the water outlet pipe 220 under the pressure in the dissolving cavity 210, and the washing water in the dissolving cavity 210 is not required to be guided into the water outlet pipe 220 by other structures. Meanwhile, one end of the water outlet pipe 220, which is located in the dissolution cavity 210, extends from top to bottom, so that the washing water in the dissolution cavity 210 can enter the water outlet pipe 220 under a certain pressure, and the gas in the dissolution cavity 210 can enter the water outlet pipe 220 after being dissolved in the washing water.
The water outlet pipe 220 comprises a horizontal section 221 and a vertical section 222 connected to one end of the horizontal section 221, and the vertical section 222 is positioned in the dissolving cavity 210; one end of the horizontal section 221 is communicated with the washing tub 100, and the other end thereof extends into the dissolving cavity 210 and is communicated with the vertical section 222; the lower end of the vertical section 222 is near the bottom of the dissolution chamber 210.
In this embodiment, a flow sensor 260 is disposed on the water outlet pipe 220 downstream of the bubble generator 230, so as to monitor the volume of the washing water liquid with microbubbles discharged from the water outlet pipe 220 into the washing tub 100 by the flow sensor 260.
Fig. 3 is a schematic structural diagram of a flow sensor 260 of an embodiment of the microbubble washing machine according to the present invention. Fig. 4 is a schematic diagram of a partial structure of a flow sensor 260 of an embodiment of the microbubble washing machine according to the present invention. Fig. 5 is a schematic structural diagram of an impeller 262 of a flow sensor 260 of an embodiment of the microbubble washing machine according to the present invention.
Referring to fig. 1 to 5, the flow sensor 260 includes a housing 261 provided with an outlet and an inlet, an impeller 262 rotatably coupled in the housing 261, and a sensing element 263; the outer shell 261 is connected in series with the water outlet pipe 220 through an outlet and an inlet; the sensing member 263 is used to detect the rotation of the impeller 262, so as to monitor the flow rate of the washing water with microbubbles per unit time when the microbubbles drive the impeller 262 to rotate. The volume of microbubble-laden wash water entering the wash tub 100 is monitored by monitoring the flow rate per unit time of the microbubble-laden wash water passing through the flow sensor 260.
In this embodiment, the impeller 262 is provided with a magnet 264, and the sensing element 263 is a magnetic sensing element for sensing the position of the magnet 264. The magnet 264 rotates with the impeller 262, the position of the magnet 264 is changed, so that the magnetic field of the magnet 264 is changed, and the sensing member 263 senses the change of the magnetic field to judge the position of the magnet 264, so that the number of rotations of the impeller 262 is measured, and the volume of the washing water with the micro-bubbles is measured.
In this embodiment, the impeller 262 includes a spindle 2621 rotatably connected to the housing 261, and a plurality of blades 2622 circumferentially arranged around the axis of the spindle 2621 and around the circumference of the spindle 2621 and disposed on the outer circumference of the spindle 2621. The vanes 2622 extend in a radial direction of the spindle 2621, and the vanes 2622 extend in an axial direction of the spindle 2621. In this embodiment, the magnet 264 is disposed on the spindle 2621. In some embodiments, the magnets 264 are disposed on the blades 2622.
Referring to fig. 1 and 2 again, the drain pipe 300 is provided with a drain valve 310, through the drain valve 310, the washing water in the dissolution chamber 210 can be selectively discharged into the washing tub 100, and the gas in the washing tub 100 enters the dissolution chamber 210, so that the air in the dissolution chamber 210 is sufficiently dissolved in the washing water (i.e., after the washing water in the dissolution chamber 210 enters the bubble generator 230, micro-bubbles cannot be generated), the washing water in the dissolution chamber 210 is discharged into the washing tub 100, and the gas in the washing tub 100 is supplemented into the dissolution chamber 210.
The upper end of the drain pipe 300 is provided with a water level sensor 320 near the dissolution chamber 210. Since the water level sensor 320 is disposed on the water discharge pipe 300, when the water level sensor 320 detects that there is no washing water in the water discharge pipe 300, it indicates that the washing water in the dissolving chamber 210 has been completely discharged, so that the gas sufficiently enters the dissolving chamber 210, and more micro bubbles can be subsequently produced. In some embodiments, the water level sensor 320 is disposed at the bottom of the dissolution chamber 210.
The bottom surface of the dissolving chamber 210 is horizontal or the bottom surface of the dissolving chamber 210 is inclined downward toward the direction of the drain pipe 300 to enable the washing water in the dissolving chamber 210 to be completely drained.
In this embodiment, the water level sensor 320 is two opposite electrodes disposed on the drain pipe 300, and whether the washing water in the dissolving chamber 210 is completely drained is determined by whether the two electrodes are conducted. Because the washing water has certain conductivity, when the two electrodes are submerged by the washing water, the two electrodes can be electrically conducted, and whether water exists at the two electrodes can be judged by detecting whether the current is conducted in a circuit connecting the two electrodes. In this embodiment, a liquid level sensor is provided in the washing tub 100 to be able to detect a liquid level height of the washing water in the washing tub 100.
In this embodiment, the water inlet valve 250, the water discharge valve 310, the water level sensor 320 and the liquid level sensor in the washing tub 100 are electrically connected to the controller.
Fig. 6 is a first flowchart of a control method of the microbubble washing machine of the present invention. Fig. 7 is a second flowchart of the control method of the microbubble washing machine of the present invention.
Referring to fig. 1 to 7, based on the above structure, the present application further provides a control method of a microbubble washing machine, including:
the washing water is introduced into the dissolving chamber 210 to dissolve the gas in the dissolving chamber 210 in the washing water under the pressure of the dissolving chamber 210, and the washing water enters the water outlet pipe 220 and is discharged into the washing tub 100 after the micro bubbles are generated by the bubble generator 230 on the water outlet pipe 220. In this embodiment, the drain valve 310 on the drain pipe 300 is closed, the inlet valve 250 on the inlet pipe 240 is opened, so that after the washing water in the dissolving cavity 210 dissolves the dissolved gas in the cavity 210, the washing water with the gas is discharged into the outlet pipe 220 under the pressure action in the dissolving cavity 210, and the micro bubbles generated by the bubble generator 230 on the outlet pipe 220 are discharged into the washing tub 100.
In this embodiment, when the water outlet pipe 220 discharges washing water with micro bubbles into the washing tub 100, the real-time volume of the washing water discharged into the washing tub 100 by the water outlet pipe 220 is detected; if the real-time volume is smaller than the preset volume, the water outlet pipe 220 is kept to discharge the washing water into the washing tub 100; if the real-time volume is greater than or equal to the real-time volume, the introduction of the washing water into the dissolution chamber 210 is cut off, so that the water outlet pipe 220 stops discharging the washing water into the washing tub 100; the remaining washing water in the dissolution chamber 210 is drained into the washing tub 100 through the drain pipe 300. Specifically, the real-time volume of the washing water discharged from the water pipe 220 into the washing tub 100 is detected by the flow sensor 260 on the water outlet pipe 220, and when the real-time volume is smaller than the preset volume, the closing of the water discharge valve 310 and the opening of the water inlet valve 250 are maintained to maintain the discharge of the microbubble washing water from the water outlet pipe 220 into the washing tub 100. When the flow sensor 260 detects that the real-time volume of the washing water discharged from the water pipe 220 into the washing tub 100 is greater than the preset volume, the bubble generating device 200 cannot generate the micro bubbles.
After the water outlet pipe 220 discharges washing water with micro bubbles with a preset volume into the washing tub 100, cutting off the introduction of the washing water into the dissolving cavity 210; the washing water remaining in the dissolution chamber 210 is drained into the washing tub 100 through the drain pipe 300, and the gas in the washing tub 100 is introduced into the dissolution chamber 210. Specifically, since the volume of the sealed dissolution chamber 210 is constant, and the volume of the gas in the dissolution chamber 210 is constant, only a predetermined volume of microbubbles can be obtained at one time. In this embodiment, after the flow sensor 260 detects that a preset volume of microbubbles is discharged into the washing tub 100, the water inlet valve 250 on the water inlet pipe 240 is closed, and the water discharge valve 310 on the water discharge pipe 300 is opened, so as to discharge the washing water in the dissolution chamber 210 into the washing tub 100, and enable the gas in the washing tub 100 to be delivered into the dissolution chamber 210; after the water level sensor 320 detects that the washing water in the dissolution chamber 210 is completely discharged, the drain valve 310 is closed.
Detecting whether the dissolution chamber 210 is empty when the dissolution chamber 210 discharges the washing water into the washing tub 100 through the drain pipe 300; if the washing water in the dissolving chamber 210 is not drained, the drain pipe 300 is maintained to drain the washing tub 100; if the washing water in the dissolving chamber 210 is exhausted, the drain pipe 300 is closed. Specifically, in the course of discharging the washing water from the dissolution chamber 210 to the washing tub 100 by opening the drain valve 310 of the drain pipe 300, whether the washing water remains in the dissolution chamber 210 is detected by the water level sensor 320 in the course of the discharge. If the two electrodes of the water level sensor 320 are electrically connected, the drain valve is kept open, and the washing water in the dissolution chamber 210 is continuously drained into the washing tub 100, and if the two electrodes of the water level sensor 320 are not electrically connected, it is indicated that the washing water in the dissolution chamber 210 is completely drained, and the drain valve 310 is closed.
The micro bubbles generated in the bubble generating device 200 are repeatedly discharged into the washing tub 100, and when the washing water in the washing tub 100 reaches a preset water level, the micro bubbles are stopped being discharged into the washing tub 100, and the washing water in the dissolution chamber 210 is discharged into the washing tub 100. In this embodiment, the micro bubbles generated in the bubble generating device 200 are repeatedly discharged into the washing tub 100 by repeatedly opening and closing the water inlet valve 250 and the water discharge valve 310, after the liquid level sensor in the washing tub 100 detects that the liquid level in the washing tub 100 reaches the preset water level, the water inlet valve 250 is closed, the water discharge valve 310 is opened to discharge the remaining washing water in the dissolution cavity 210 into the washing tub 100, the water discharge valve 310 is closed, and the controller controls the driving mechanism to drive the washing tub 100 to rotate, so as to clean the clothes in the washing tub 100.
Fig. 8 is a general flowchart of a control method of the microbubble washing machine of the present invention.
Referring to fig. 1 to 8, in the present embodiment, the bubble generating device 200 is used as a part of a conveying mechanism for conveying washing water into the washing tub 100. In some embodiments, the washing tub 100 is additionally provided with a structure for delivering washing water into the washing tub 100.
In the normal washing mode, the washing water is introduced into the dissolving chamber 210, and the washing water in the dissolving chamber 210 is directly discharged into the washing tub 100 through the drain pipe 300, after the liquid level height in the washing tub 100 reaches a preset height, the introduction of the washing water into the dissolving chamber 210 is stopped, the washing water in the dissolving chamber 210 is completely discharged into the washing tub 100, and the washing tub 100 is rotated to wash the laundry.
Specifically, in the conventional mode, the water inlet valve 250 on the water inlet pipe 240 and the water discharge valve 310 on the water discharge pipe 300 are opened, and the washing water introduced into the dissolution chamber 210 is directly transferred into the washing tub 100. In the process of supplying the washing water into the washing tub 100, after the liquid level sensor in the washing tub 100 detects that the liquid level in the washing tub 100 reaches the preset liquid level height, the water inlet valve 250 on the water inlet pipe 240 is closed, and the water discharge valve 310 on the water discharge pipe 300 is kept open. If the two electrodes of the water level sensor 320 are electrically connected, the drain valve is kept open, and the washing water in the dissolution chamber 210 is continuously drained into the washing tub 100, and if the two electrodes of the water level sensor 320 are not electrically connected, it is indicated that the washing water in the dissolution chamber 210 is completely drained, and the drain valve 310 is closed.
In the present invention, when the washing water is discharged into the washing tub 100 through the drain pipe 300, air can be simultaneously introduced into the dissolving chamber 210, and the air intake of the dissolving chamber 210 and the water intake of the washing tub 100 are simultaneously performed, thereby saving the washing time of the washing machine.
