Description

Technical Field

[0001] The utility model relates to the technical field of household electrical appliances, in particular to a traction rope storage and release component, a lifting control mechanism and a clothes drying machine. Background Art

[0002] The clothes drying machine drives the wire reel to rotate by a motor so that the wire reel winds or releases the traction rope to achieve the lifting and lowering control of the drying rack. Generally, multiple traction ropes are used to connect the drying rack to reduce the load of a single traction rope. Therefore, the wire reel carried by the existing clothes drying machine usually includes multiple wire reels. The assembly error between the motor and the wire reel and the mechanical wear during long-term use will aggravate the asynchronism of the actions between different wire reels, which is manifested as multiple wire reels are difficult to rotate or stop rotating synchronously. This leads to the problem of asynchronous winding or releasing of the traction ropes wound on different wire reels, making it difficult to ensure the consistency of the lifting and lowering actions of the parts of the drying rack connected to different traction ropes, which easily causes the drying rack to become unstable, tilted or shaken.

[0057] Embodiment 3

[0058] See also Figure 7 and Fig. 9 The rotation direction of the first wire storage groove 221 is opposite to that of the second wire storage groove 222, and the two are located on the outer periphery of the same rotating shaft 21.

[0059] like Fig. 9 As shown, the extension direction of the axis of the rotating shaft 21 is taken as the Y-axis direction of the plane rectangular coordinate system. When the side of the reel 20 is unfolded in the plane rectangular coordinate system, the slope of the straight line formed by the first wire storage groove 221 and the slope of the straight line formed by the second wire storage groove 222 have opposite positive and negative properties, that is, one of them has a negative slope and the other has a positive slope.

[0060] Further, Figure 7 In the illustrated embodiment, the first rope end fixing portion 223 is disposed at the right end of the first wire storage groove 221, and the second rope end fixing portion 224 is disposed at the left end of the second wire storage groove 222.

[0061] Specifically, the left and right ends of the first wire storage groove 221 and the left and right ends of the second wire storage groove 222 are defined as follows: if the two ends of the rotating shaft 21 are respectively defined as the first end and the second end, then the left end of the first wire storage groove 221 is the end of the first wire storage groove 221 relatively close to the first end, the right end of the first wire storage groove 221 is the end of the first wire storage groove 221 relatively close to the second end, the left end of the second wire storage groove 222 is the end of the second wire storage groove 222 relatively close to the first end, and the right end of the second wire storage groove 222 is the end of the second wire storage groove 222 relatively close to the second end.

[0062] Embodiment 4

[0063] Figure 3-4 In the illustrated embodiment, the rotating shaft 21 is a cylindrical structure, that is, the radius of the rotating shaft 21 is a constant value in the axial direction of the rotating shaft 21. Figure 3-4 On the basis of the illustrated embodiment, the rotating shaft 21 may also be a rotating body structure with a taper, that is, the radius of the rotating shaft 21 tends to increase from one end of the rotating shaft 21 to the other end of the rotating shaft 21. If the power output member 10 drives the rotating shaft 21 to rotate at a fixed rotational angular velocity, the larger the radius of the position on the rotating shaft 21, the greater the linear velocity during its rotation. Therefore, when the reel 20 winds the traction rope, the speed of the first wire storage groove 221 winding up the first traction rope 301 and the speed of the second wire storage groove 222 winding up the second traction rope 302 increase in the direction of increasing the radius of the rotating shaft 21 and decrease in the direction of decreasing the radius of the rotating shaft 21.

[0064] Specifically, the two ends of the rotating shaft 21 are respectively the first end and the second end, the radius of the first end is greater than the radius of the second end, and the radius of the rotating shaft 21 decreases from the first end to the second end. The first rope end fixing portion 223 is provided at an end of the first wire storage groove 221 relatively close to the first end, and the second rope end fixing portion 224 is provided at an end of the second wire storage groove 222 relatively close to the first end. The position of the first rope end fixing portion 223 is the starting position for the first traction rope 301 to be wound and stored in the first wire storage groove 221, and the position of the second rope end fixing portion 224 is the starting position for the second traction rope 302 to be wound and stored in the second wire storage groove 222. As the rotating shaft 21 continues to rotate, the winding rates of the first traction rope 301 and the second traction rope 302 gradually decrease.

[0065] In this way, when the drying rack 50 is at the lowest point and the length of the first suspension section and the length of the second suspension section are both at the maximum value, the traction rope storage assembly 100 has the maximum rewinding rate at the beginning of rewinding the first traction rope 301 and the second traction rope 302, so the drying rack 50 has the maximum instantaneous rising speed at this time. As the power output member 10 drives the rotating shaft 21 to continue to rotate, the length of the first suspension section and the second suspension section gradually decreases, the total length of the first winding section and the total length of the second winding section gradually increase, the rewinding rates of the first traction rope 301 and the second traction rope 302 gradually decrease, and the rising speed of the drying rack 50 gradually decreases, thereby reducing the kinetic energy of the drying rack 50 when it reaches the highest point, thereby reducing the impact of the drying rack 50 on the main unit 40.

[0067] Figure 7 In the illustrated embodiment, the rotating shaft 21 is a cylindrical structure, that is, the radius of the rotating shaft 21 is a constant value in the axial direction of the rotating shaft 21. Figure 7 On the basis of the illustrated embodiment, the third shaft segment 213 and the fourth shaft segment 214 can also be a rotating body structure with a taper. For example, the radius of the rotating shaft 21 can be set as: the radius of the third shaft segment 213 decreases in the direction away from the fourth shaft segment 214, and the radius of the fourth shaft segment 214 decreases in the direction away from the third shaft segment 213; in addition, the radius of the rotating shaft 21 can also be set as: the radius of the third shaft segment 213 increases in the direction away from the fourth shaft segment 214, and the radius of the fourth shaft segment 214 increases in the direction away from the third shaft segment 213.

[0068] If the power output member 10 drives the rotating shaft 21 to rotate at a fixed angular velocity, a position with a larger radius on the rotating shaft 21 can produce a greater linear velocity. Therefore, when the reel 20 winds the traction rope, the speed at which the first wire storage groove 221 reels in the first traction rope 301 increases in the direction of increasing radius of the third shaft segment 213, and the speed at which the second wire storage groove 222 reels in the second traction rope 302 decreases in the direction of decreasing radius of the fourth shaft segment 214.

[0069] Specifically, the two ends of the third shaft section 213 are the third end and the fourth end, respectively, the radius of the third end is greater than the radius of the fourth end, and the radius of the third shaft section 213 decreases from the third end to the fourth end; the two ends of the fourth shaft section 214 are the fifth end and the sixth end, respectively, the radius of the fifth end is greater than the radius of the sixth end, and the radius of the fourth shaft section 214 decreases from the fifth end to the sixth end. The first rope end fixing portion 223 is provided at one end of the first wire storage groove 221 relatively close to the third end, and the second rope end fixing portion 224 is provided at one end of the second wire storage groove 222 relatively close to the fifth end. The position of the first rope end fixing portion 223 is the starting position of the first traction rope 301 being wound and stored in the first wire storage groove 221, and the position of the second rope end fixing portion 224 is the starting position of the second traction rope 302 being wound and stored in the second wire storage groove 222. As the rotating shaft 21 continues to rotate, the winding rates of the first traction rope 301 and the second traction rope 302 gradually decrease.

[0070] In this way, when the drying rack 50 is at the lowest point and the length of the first suspension section and the length of the second suspension section are both at the maximum value, the traction rope storage assembly 100 has the maximum rewinding rate at the beginning of rewinding the first traction rope 301 and the second traction rope 302, so the drying rack 50 has the maximum instantaneous rising speed at this time. As the power output member 10 drives the rotating shaft 21 to continue to rotate, the length of the first suspension section and the second suspension section gradually decreases, the total length of the first winding section and the total length of the second winding section gradually increase, the rewinding rates of the first traction rope 301 and the second traction rope 302 gradually decrease, and the rising speed of the drying rack 50 gradually decreases, thereby reducing the kinetic energy of the drying rack 50 when it reaches the highest point, thereby reducing the impact of the drying rack 50 on the main unit 40.

[0071] Embodiment 6

[0072] Figure 5 In the illustrated embodiment, the rotating shaft 21 is a cylindrical structure, that is, the radius of the rotating shaft 21 is a constant value in the axial direction of the rotating shaft 21. Figure 5 On the basis of the illustrated embodiment, the first shaft segment 211 and the second shaft segment 212 may also be a rotating body structure with a taper. For example, the radius of the rotating shaft 21 may be set as follows: the radius of the first shaft segment 211 decreases in the direction away from the second shaft segment 212, and the radius of the second shaft segment 212 increases in the direction away from the first shaft segment 211; in addition, the radius of the rotating shaft 21 may also be set as follows: the radius of the first rotating shaft 21 increases in the direction away from the second shaft segment 212, and the radius of the second shaft segment 212 decreases in the direction away from the first shaft segment 211.

[0073] If the power output member 10 drives the rotating shaft 21 to rotate at a fixed angular velocity, a position with a larger radius on the rotating shaft 21 can produce a greater linear velocity. Therefore, when the reel 20 winds the traction rope, the speed at which the first wire storage groove 221 reels in the first traction rope 301 increases in the direction in which the radius of the first shaft segment 211 increases, and the speed at which the second wire storage groove 222 reels in the second traction rope 302 decreases in the direction in which the radius of the second shaft segment 212 decreases.

[0074] Specifically, the two ends of the first shaft section 211 are the seventh end and the eighth end respectively, the radius of the seventh end is greater than the radius of the eighth end, and the radius of the first shaft section 211 decreases from the fourth end to the eighth end; the two ends of the second shaft section 212 are the ninth end and the tenth end respectively, the radius of the ninth end is greater than the radius of the tenth end, and the radius of the second shaft section 212 decreases from the ninth end to the tenth end. The first rope end fixing portion 223 is provided at one end of the first wire storage groove 221 relatively close to the seventh end, and the second rope end fixing portion 224 is provided at one end of the second wire storage groove 222 relatively close to the ninth end. The position of the first rope end fixing portion 223 is the starting position of the first traction rope 301 being wound and stored in the first wire storage groove 221, and the position of the second rope end fixing portion 224 is the starting position of the second traction rope 302 being wound and stored in the second wire storage groove 222. As the rotating shaft 21 continues to rotate, the winding rates of the first traction rope 301 and the second traction rope 302 gradually decrease.

[0075] In this way, when the drying rack 50 is at the lowest point and the length of the first suspension section and the length of the second suspension section are both at the maximum value, the traction rope storage assembly 100 has the maximum rewinding rate at the beginning of rewinding the first traction rope 301 and the second traction rope 302, so the drying rack 50 has the maximum instantaneous rising speed at this time. As the power output member 10 drives the rotating shaft 21 to continue to rotate, the length of the first suspension section and the second suspension section gradually decreases, the total length of the first winding section and the total length of the second winding section gradually increase, the rewinding rates of the first traction rope 301 and the second traction rope 302 gradually decrease, and the rising speed of the drying rack 50 gradually decreases, thereby reducing the kinetic energy of the drying rack 50 when it reaches the highest point, thereby reducing the impact of the drying rack 50 on the main unit 40.
