DETAILED DESCRIPTION
[0029] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0030] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.
[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0032] See also Figure 1-Figure 7 The utility model discloses a directional rotating washing machine, comprising a body 10, a cleaning assembly and a non-return assembly, wherein a receiving cavity is provided in the body 10. The cleaning assembly comprises a dehydration cylinder 20 and a pulsator 30, wherein the dehydration cylinder 20 is rotatably mounted in the receiving cavity, and the pulsator 30 is rotatably mounted in the dehydration cylinder 20.
[0033] Specifically, the check assembly includes a driving member 41, a driving seat 43, a driving shaft 42, a first check member and a second check member. The driving seat 43 is connected to the bottom end of the dehydration cylinder 20, and the driving shaft 42 is installed in the accommodating cavity. One end of the driving shaft 42 is formed as a driving end, and the other end of the driving shaft 42 is formed as a transmission end. The driving end extends into the dehydration cylinder 20 through the driving seat 43 and is connected to the impeller 30, and the driving member 41 can be used to drive the transmission end to rotate.
[0034] In addition, a first check member is provided on the impeller 30, and a second check member is provided on the dehydration cylinder 20. The first check member and the second check member are used to separate when the drive shaft 42 rotates around a first direction, so that the drive shaft 42 drives the impeller 30 to rotate; the first check member and the second check member are used to connect when the drive shaft 42 rotates around a second direction, so as to guide the dehydration cylinder 20 to rotate.
[0035] Specifically, based on the above structure, when the directional rotating washing machine of the utility model is used, the directional rotating washing machine has a washing state and a dehydration state:
[0036] In the washing state, the clothes can be put into the dehydration cylinder 20 in the accommodating cavity, and the driving member 41 can be started. The driving member 41 can drive the driving shaft 42 to rotate around the first direction. When the transmission end of the driving shaft 42 rotates around the first direction, the driving member 41 drives the impeller 30 to rotate around the first direction. The first check member on the impeller 30 is disengaged from the second check member on the dehydration cylinder 20 at this time. Therefore, when the driving shaft 42 rotates, it can drive the impeller 30 to rotate. At this time, the impeller 30 rotates in the dehydration cylinder 20. In this state, the dehydration cylinder 20 can be non-rotating or driven by inertia to have a lower rotation speed (which can increase the water flow rate) when the impeller 30 rotates, and the impeller 30 can rotate relative to the dehydration cylinder 20 in the dehydration cylinder 20, so that the impeller 30 can move water and clothes in the dehydration cylinder 20, increase the water flow rate, and realize the cleaning of clothes with good cleaning effect.
[0037] In the dehydration state, the driving member 41 is started, and the driving member 41 can drive the driving shaft 42 to rotate around the second direction. The driving member 41 can drive the driving shaft 42 to rotate around the second direction. When the transmission end of the driving shaft 42 rotates around the second direction, the driving shaft 42 drives the impeller 30 to rotate around the second direction, so that the first check member is connected to the second check member on the dehydration cylinder 20, and then the rotation of the impeller 30 can drive the dehydration cylinder 20 to rotate together. The impeller 30 and the dehydration cylinder 20 rotate together at high speed, and high-speed dehydration can be performed; and the impeller 30 can rotate in the dehydration cylinder 20 along with the dehydration cylinder 20, and throw out water inside to improve the dehydration effect.
[0038] The same driving member 41 drives the driving shaft 42 to rotate in two opposite directions. When the driving shaft 42 rotates in different directions, the first check member and the second check member can be separated or connected to guide the pulsator 30 or the dehydration drum 20 to rotate in a directional manner, thereby achieving the functions of washing and dehydrating clothes, with good washing effect and good spin drying effect. There is no need to set up multiple motors or clutches, simplifying the driving structure and reducing production costs.
[0039] Specifically, the first check piece and the second check piece in the present application are arranged in the following two ways:
[0040] See also Figure 1-Figure 4 , the first check piece is a check rod 45, and the second check piece is a check groove 46:
[0041] Based on this structure, the check rod 45 can be installed on the impeller 30, and a check groove 46 can be set on the dehydration cylinder 20 accordingly. The check groove 46 can be set on the dehydration cylinder 20 or on the driving seat 43 connected to the dehydration cylinder 20.
[0042] When the driving shaft 42 rotates in the first direction, the check rod 45 on the impeller 30 moves away from the check groove 46, and the impeller 30 and the dehydration drum 20 are in a state of separation. At this time, the rotation of the driving shaft 42 can drive the impeller 30 to rotate relative to the dehydration drum 20 to achieve cleaning of the clothes.
[0043] When the driving shaft 42 rotates in the second direction, the check groove 46 of the impeller 30 first moves close to the check rod 45 on the dehydration drum 20. At this time, the check rod 45 can abut against the check groove 46 to limit the rotation of the impeller 30 relative to the dehydration drum 20. At this time, the driving shaft 42 drives the impeller 30 to rotate, and the dehydration drum is driven to rotate together with the abutment restriction of the check rod 45 and the check groove 46 to achieve dehydration of the clothes.
[0044] See also Figure 5-Figure 7 , the first check piece is a check groove 46, and the second check piece is a check rod 45:
[0045] When the driving shaft 42 rotates in the first direction, the check groove 46 on the impeller 30 moves away from the check rod 45 on the dehydration drum 20, and the impeller 30 and the dehydration drum 20 are in a state of separation from each other. At this time, the rotation of the driving shaft 42 can drive the impeller 30 to rotate relative to the dehydration drum 20 to achieve cleaning of the clothes.
[0046] When the driving shaft 42 rotates in the second direction, the check groove 46 of the impeller 30 first moves close to the check rod 45 on the dehydration drum 20, and the check rod 45 can abut against the check groove 46 to limit the rotation of the impeller 30 relative to the dehydration drum 20. At this time, the driving shaft 42 drives the impeller 30 to rotate, and the dehydration drum is driven to rotate together with the abutment restriction of the check rod 45 and the check groove 46 to achieve dehydration of the clothes.
[0047] Specifically, a guiding slope 461 is provided on the side wall of the check groove 46. When the driving shaft 42 rotates in the second direction, the impeller 30 rotates, and the check rod 45 can slide into the check groove 46 and abut against the guiding slope 461 of the check groove 46; and when the driving shaft 42 rotates in the first direction, the guiding slope 461 guides the check rod 45 to slide out of the check groove 46. In this way, the slope structure guides the check rod 45 to abut against or separate from the check groove 46, so that the rotation is smooth and the jamming is reduced.
[0048] Furthermore, a sliding slope that matches the guide slope 461 can be provided at the bottom end of the check rod 45, and the sliding slope and the guide slope 461 are structurally matched, so that the sliding slope of the check rod 45 cooperates with the guide slope 461 of the check groove 46, which can better guide the check rod 45 and the check groove 46 to slide in or out.
[0049] Furthermore, in order to further facilitate the disengagement of the check rod 45, the check rod 45 is connected to an elastic component 451. When the check rod 45 is set on the impeller 30, the check rod 45 is connected to the impeller 30 through the elastic component 451, and when the check rod 45 is set on the dehydration cylinder 20, the check rod 45 is connected to the dehydration cylinder 20 through the elastic component 451.
[0050] The elastic component 451 provides an elastic stress. Under the action of the elastic stress, when the check rod 45 is disengaged from the check groove 46, it rotates and escapes. In the inclined direction of the guide slope 461, the check rod 45 can be gradually pressed, so that the elastic component 451 is compressed, driving the check rod 45 to quickly disengage from the check groove 46. After the check rod 45 escapes, the elastic component 451 is in a contracted state. On the contrary, when the check rod 45 is connected to the check groove 46, the check rod 45 slides into the check groove 46 and maintains a contact limit state under the action of the elastic stress.
[0051] Furthermore, in the present embodiment, a plurality of first check members and a plurality of second check members are provided, and the plurality of first check members and the plurality of second check members are spaced apart in the rotation direction. In this way, the positioning rotation of the impeller 30 and the dehydration drum 20 can be achieved by cooperating with the first check members and the second check members at different positions in the rotation direction of the impeller 30.
[0052] Furthermore, a rotating sleeve 431 may be provided on the driving seat 43, and the driving end extends into the dehydration cylinder 20 and is connected to the impeller 30 through the rotating sleeve 431, and the driving end is installed in the rotating sleeve 431 through the bearing 44. In this way, the driving shaft 42 can achieve rotational cooperation with the rotating sleeve 431 of the driving seat 43 through the bearing 44, so that the rotation is smooth. The rotational force acts on the rotating sleeve 431, and the rotational force acts on the rotating sleeve 431 of the driving seat 43, providing a driving force, and it is easier to increase the rotation speed of the driving seat 43 and the dehydration cylinder 20 connected to the driving seat 43.
[0053] Furthermore, a first through hole is provided at the top of the rotating sleeve 431, and the driving end extends into the dehydration barrel 20 through the first through hole, and a first sealing ring 432 is clamped between the inner wall of the first through hole and the outer wall of the driving end. In this way, the first sealing ring 432 can be used to seal the connection position between the driving end of the driving shaft 42 and the dehydration barrel to prevent water leakage at the assembly position, thereby improving the sealing of the internal parts of the rotating sleeve 431.
[0054] Furthermore, the bottom end of the rotating sleeve 431 is sealed with a pressure cover, and a second through hole is provided on the pressure cover; the driving shaft 42 extends into the rotating sleeve 431 through the second through hole, so that the driving shaft 42 can penetrate into the rotating sleeve 431 through the second through hole of the pressure cover, and a second sealing ring 433 is clamped between the inner wall of the rotating sleeve 431 and the outer wall of the driving end. The second sealing ring 433 is used to seal the bottom end of the rotating sleeve 431, which can also improve the sealing of the internal parts of the rotating sleeve 431.
[0055] Furthermore, the above-mentioned drive seat 43 is sealed and connected to the bottom end of the dehydration cylinder 20, and is fixedly connected to the inner wall of the bottom end of the dehydration cylinder 20, that is, the drive seat 43 is formed as the bottom wall of the dehydration cylinder 20. Specifically, the drive seat 43 can be directly formed on the bottom end of the dehydration cylinder 20, or it can be assembled on the bottom end of the dehydration cylinder 20 by means of screws and other structures. The drive seat 43 is directly the bottom end structure of the dehydration cylinder 20. When the drive shaft 42 drives the dehydration cylinder 20 to rotate, it is a direct drive, and the rotation speed is higher during rotation.
[0056] Furthermore, abutting steps can be provided on the outer periphery of the bottom end of the driving seat 43, and the bottom peripheral edge of the dehydration cylinder 20 is against the abutting steps, and the inner wall of the dehydration cylinder 20 is provided with a plurality of protruding blocks, and the bottom end of the protruding block located at the bottom of the inner wall of the dehydration cylinder 20 is against the top peripheral edge of the driving seat 43. In this way, the plurality of protruding blocks form an uneven situation on the inner wall of the dehydration cylinder 20, which can make it easier to throw out the water flow during dehydration, and the dehydration effect is better. The abutting steps of the bottom protruding block and the driving seat 43 realize the upper and lower limit of the driving seat 43, and improve the assembly stability of the driving seat 43.
[0057] Furthermore, a plurality of reinforcing ribs are provided at the bottom end of the drive seat 43, and the reinforcing ribs extend along the radial direction of the drive seat 43, and the plurality of reinforcing ribs are spaced apart in the circumferential direction of the drive seat 43. In this way, the drive seat 43 is reinforced by reinforcing ribs in both the circumferential and radial directions, and the strength of the drive seat 43 is better, and the transmission of the drive seat 43 is more stable when rotating.
[0058] Furthermore, the driving member 41 includes a driving motor, and the rotating shaft of the driving motor is connected to the transmission end. That is, in this embodiment, the rotating shaft of the driving motor drives the driving shaft 42 to rotate, and the driving structure is simple and stable.
[0059] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
