In addition, the bottom of the outer cylinder 30 is provided with a vent hole 31 communicating the inside and outside of the outer cylinder 30, and the vent hole 31 communicates with the air outlet hole 11 of the air pump 10, so that the air blown out from the air outlet hole 11 of the air pump 10 can flow into the vent hole 31.
As shown in fig. 2, the inner tube 20 is provided inside the outer tube 30, the inner tube 20 is provided coaxially with the outer tube 30, and the inner tube 20 is provided rotatably in the axial direction. The bottom of the inner cylinder 20 is provided with an air guide hole 21 for communicating the inside and the outside of the inner cylinder 20, and a positioning groove 22 is formed on the wall surface of the bottom of the inner cylinder 20, which is close to the outer cylinder 30. Wherein the distance from the air vent to the axial direction of the inner cylinder 20 is equal to the distance from the air vent 31 to the axial direction of the outer cylinder 30. Thus, when the inner drum 20 rotates, the air vent 21 can be overlapped with the air vent 31 during the rotation of the inner drum 20, i.e. the air vent 21 is positioned right above the air vent 31, so that the air in the air vent 31 can flow into the inner drum 20 of the pulsator washing machine 100 through the air vent 21.
Further, a retractor 40 is provided below the outer cylinder 30, the retractor 40 including: the fixed rod 41 and the locating column 42, wherein, the fixed rod 41 runs through the bottom of urceolus 30, and the locating column 42 nests in the fixed rod 41, and the locating column 42 telescopic setting is in the fixed rod 41, and the locating column 42 equals the axial direction's of urceolus 30 distance and constant head tank 22 to the axial direction of inner tube 20. When the positioning column 42 is extended, the positioning column 42 is pressed by the bottom surface of the inner guide tube 20 and cannot be fully extended (hereinafter referred to as a first state), so that the end portion of the positioning column 42 can be in contact with the bottom of the inner guide tube 20, when the inner guide tube 20 rotates in the axial direction, the positioning groove 22 also rotates in the axial direction, when the positioning groove 22 rotates to the positioning column 42, the wall surface of the bottom of the outer guide tube 30 is not acted by the positioning column 42, the positioning column 42 is fully extended into the positioning groove 22 (hereinafter referred to as a second state), and the inner guide tube 20 stops rotating, and the air guide hole 21 coincides with the air vent 31.
Wherein, in some embodiments, as shown in fig. 2, the retractor 40 further comprises: and a driving device 43, wherein the driving device 43 is connected with the positioning column 42 and is used for driving the positioning column 42 to extend or retract into the fixed rod 41. In this manner, the drive 43 can power the movement of the positioning post 42.
It will be appreciated that the driving means 43 may be arranged to convert the driving force of the driving means 43 into a reciprocating motion of the positioning column 42 in the axial direction of the fixing rod by means of a transmission mechanism.
Alternatively, the transmission mechanism may be a cam structure; alternatively, the driving device 43 may be a crank-slider mechanism; alternatively, the driving device 43 may be a reciprocating screw mechanism, and the specific structure of the transmission mechanism is not limited in the present application.
In addition, to avoid the positioning post 42 being in the first state, the positioning post 42 is pushed by the transmission mechanism, such that the inner cylinder 20 is damaged due to the excessive rigidity of the positioning post 42, or such that the positioning post 42 is damaged (e.g., broken, deformed) due to the excessive rigidity of the inner cylinder 20. This seriously affects the normal operation of the pulsator washing machine 100. Thus, the connection of the positioning post 42 to the transmission mechanism may be an elastic connection. For example, a spring is provided at the connection between the positioning post 42 and the transmission mechanism, and when the end of the positioning post 42 contacts the inner cylinder 20 and the transmission mechanism continues to push the positioning post 42, the spring is compressed under force to avoid damage to the inner cylinder 20 or the positioning post 42. When the end of the positioning column 42 is located right below the positioning groove 22, the end of the positioning column 42 is not blocked by the wall surface of the inner cylinder 20, the spring is reset, and the reset force provided by the spring enables the end of the positioning column 42 to extend into the positioning groove 22, and the positioning groove 22 is clamped, so that the air guide hole 21 is located right above the air vent hole 31, and therefore air in the air vent hole 31 can flow into the inner cylinder 20 of the pulsator washing machine 100 through the air guide hole 21.
Fig. 3 illustrates a circuit connection diagram of an pulsator washing machine in which an embodiment of the present application is improved, and the controller 50 is electrically connected to the retractor 40 for controlling the extension or retraction of the positioning column 42 of the retractor 40, as shown in fig. 3.
The pulsator washing machine 100 provided in an embodiment of the present application includes: the air pump 10, the urceolus 30, the inner tube 20, wherein, the air pump 10 is used for blowing out gas, the bottom of urceolus 30 is provided with the air vent 31 that communicates outside urceolus 30, air pump 10 communicates with this air vent 31, thereby the gas that blows out in the air pump 10 can be through this air vent 31 entering to the urceolus 30, inner tube 20 and urceolus 30 coaxial arrangement, and rotationally set up in urceolus 30 along circumference, the bottom of urceolus 30 is provided with the air vent 21 that communicates inside and outside the inner tube 20, thereby the gas that enters into in the urceolus 30 can enter into in the inner tube 20 along air vent 21, thereby the gas that gets into in the inner tube 20 can dissolve into the bubble water into, the water that contains the bubble carries out the clothing washing under the stirring of rotary drum washing machine 100, through the rupture of bubble and the washing of rivers, the washing of the attached spot of clothing surface is got rid of acceleration, improve rotary drum washing machine 100 washing ratio. And, the bubbles continuously emerge from the bottom upwards, impact the detergent (e.g., laundry detergent, washing powder, etc.) added into the inner tub, thereby accelerating dissolution of the detergent, enabling the detergent to be better mixed with the laundry, thereby reducing the amount of the detergent, reducing the rinsing times and rinsing time of the laundry, reducing the amount of water and electricity required for washing the laundry, and enabling the pulsator washing machine 100 to save more energy.
Also, the pulsator washing machine 100 further includes: a retractor 40 and a controller 50, wherein the retractor 40 is disposed below the outer tub 30, the retractor 40 comprising: a fixed rod 41 penetrating through the bottom of the outer cylinder 30 and a positioning column 42 nested on the fixed rod 41, wherein the positioning column 42 can be telescopically arranged in the fixed rod 41; when the positioning column 42 extends, the end of the positioning column 42 contacts with the bottom of the inner cylinder 20, when the inner cylinder 20 rotates in the axial direction, the positioning groove 22 of the inner cylinder 20 also rotates in the axial direction, when the positioning groove 22 rotates to the position right above the positioning column 42 (hereinafter referred to as the optimal washing state), the positioning column 42 extends into the positioning groove 22, so that the air vent hole 21 is located right above the air vent hole 31, and thus, the air flowing through the air vent hole 31 can directly enter the inner cylinder 20 through the air vent hole 21, the air is guaranteed to enter the inner cylinder 20 to the maximum extent, and the number of bubbles in water can be increased.
In addition, a controller 50 is electrically connected to the retractor 40 for controlling the extension or retraction of the positioning posts 42 of the retractor 40. Therefore, when the pulsator washing machine 100 is dehydrated, the relative position of the inner tub 20 and the outer tub 30 is changed (i.e., the pulsator washing machine 100 cannot be in an optimal washing state), the positioning column 42 can be extended by the controller 50, and simultaneously the inner tub 20 is rotated to extend the positioning column 42 into the positioning groove 22, so that the inner tub 20 and the outer tub 30 are fixed, and the inner tub 20 cannot be rotated continuously, so that the pulsator washing machine 100 can maintain the optimal washing state. When the inner cylinder 20 is required to be rotated (for example, dehydration is performed by rotation of the inner cylinder 20), the positioning column 42 can be contracted by the controller 50 to release the restriction of the positioning column 42 to the inner cylinder 20, and the inner cylinder 20 can be rotated. In this way, the pulsator washing machine 100 can be in an optimal washing state or the inner tub 20 can be rotated by the controller 50, so that the user operation is convenient and the user experience is improved.
In order to improve the stability of the positioning post 42 in the process of contacting and sliding with the bottom of the inner cylinder 20, fig. 4 shows a schematic cross-sectional structure of the outer cylinder provided by the embodiment of the application, in some embodiments, an annular groove 23 is further formed on a wall surface of the bottom of the inner cylinder 20, which is close to the outer cylinder 30, as shown in fig. 4, the annular groove 23 is coaxially arranged with the outer cylinder 30, the positioning groove 22 is arranged in the annular groove 23, and when the end portion of the positioning post 42 protrudes, the end portion (i.e. in the first state) of the positioning post 42 can contact with the bottom of the annular groove 23, and when the inner cylinder 20 rotates in the axial direction, the positioning post 42 slides along the annular groove 23 relative to the annular groove 23. When the positioning groove 22 in the annular groove 23 moves to above the positioning column 42, the positioning column 42 is changed from the first state to the second state, so that the pulsator washing machine 100 is in an optimal washing state. In this way, the positioning post 42 can relatively slide along the annular groove 23, so that the occurrence of the situation that the positioning post 42 cannot extend into the positioning groove 22 due to the offset of the positioning post 42 is reduced.
Further, it is understood that in some embodiments, pulsator washing machine 100 further includes: and the motor 60, the motor 60 is in transmission connection with the inner cylinder 20 and is used for enabling the inner cylinder 20 to rotate along the axial direction. Thus, the rotation of the motor 60 can rotate the inner cylinder 20 to rotate the positioning slot 22 above the positioning post 42.
Alternatively, the motor 60 may be in a belt drive connection with the inner barrel 20, or may be in a gear drive, a chain drive, or the like, which is not limited in this regard.
Wherein the motor 60 may be located below the outer tub 30, the pulsator washing machine further includes: the transmission shaft, the motor 60 is connected with the transmission shaft in a transmission way, and is coaxially arranged with the inner cylinder and the outer cylinder, and the transmission shaft penetrates through the outer cylinder 30 and is connected with the inner cylinder 20 so that the inner cylinder 20 can be rotatably arranged in the outer cylinder 30.
In addition, the connection of the drive shaft to the inner barrel 20 may be a fixed connection, for example, the fixed connection may be welding, riveting, or the like. The connection of the drive shaft to the inner barrel 20 may also be a detachable connection, such as a threaded connection, a bayonet connection, a snap connection, or the like, to secure the drive shaft to the inner barrel 20 such that the inner barrel 20 can rotate with the drive shaft when the drive shaft is rotating.
