Description

Technical Field

[0001] This invention belongs to the field of household appliance technology, specifically, it relates to a washing machine. Background Technology

[0002] Traditional washing machines are mostly placed directly on the ground. When users need to move or transport the washing machine, it usually requires manual labor, which is labor-intensive and inconvenient. Currently, some washing machines have casters installed on the bottom. While this facilitates movement to some extent, the casters are not stable and can cause accidents during operation. Existing washing machines have undergone some improvements to overcome these shortcomings.

[0003] For example, Chinese patent application number 201410137755.6 discloses a washing machine that is easy to move. The washing machine has four wheels installed at the four corners of its bottom, allowing the user to push it to its destination with minimal effort. Additionally, four lifting screws are installed at the bottom of the washing machine, which can be rotated to raise or lower it. When the washing machine is not in use, the lifting screws are lowered to support it, suspending the four wheels and keeping the machine stable on the ground. When the washing machine needs to be moved, the lifting screws are raised, allowing the four wheels to be placed on the ground and pushed. While this patented washing machine provides a certain degree of stability and fixation during operation, the user needs to squat down to rotate the lifting screws to make the wheels support the ground or suspend them. Due to the relatively heavy weight of the washing machine, it still presents some operational difficulties for elderly people and women with limited strength.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art. The present invention provides a washing machine that is more convenient, faster and more time-saving and labor-saving to move.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0007] A washing machine, comprising:

[0008] The lifting wheel assembly and the moving wheel assembly are respectively arranged on opposite sides of the bottom of the washing machine; the lifting wheel assembly includes a lifting wheel bracket and lifting wheels mounted on the lifting wheel bracket;

[0009] At least two guide members of a certain height are respectively installed at the bottom of the washing machine, and outwardly extending guide members are respectively installed on both sides of the lifting wheel bracket, and the guide members are slidably connected to the guide members;

[0010] A foot pedal is rotatably mounted on the bottom of the washing machine in a vertical direction. One end of the foot pedal is provided with a slider, which is fixedly connected to the lifting wheel assembly. The side of the slider near the foot pedal engages with the inclined end face of the foot pedal.

[0011] The foot pedal is controlled to rotate vertically up and down by the other end of the foot pedal, and then the slider drives the lifting wheel assembly to move back and forth along the extension direction of the foot pedal, and drives the guide to slide up and down along the guide to adjust the distance between the lifting wheel and the bottom of the washing machine.

[0012] In the above solution, by setting the end face of the foot pedal to cooperate with the inclined end face of the slider, when the foot pedal rotates up and down in the vertical direction, the slider will move back and forth along the extension direction of the foot pedal, thereby causing the guide to slide up and down along the guide, realizing the raising or lowering of the lifting wheel relative to the ground. The moving device is simpler and the lifting operation of the lifting wheel is more simplified, which not only reduces production costs but also improves the user experience.

[0013] Furthermore, a guide groove is provided on the side wall of the guide member facing the lifting wheel bracket;

[0014] The guide member has a first end on the side facing the washing machine and a second end on the side facing away from the washing machine, and the guide groove extends obliquely downward from the first end to the second end.

[0015] The guide is inserted into the guide groove and slides up and down along the extension direction of the guide groove.

[0016] In the above scheme, by setting the structure of the guide member to have an inclined extended guide groove, it is easier to guide the lifting wheel assembly to move up and down, thereby simplifying the lifting motion of the lifting wheel.

[0017] Furthermore, one end of the foot pedal extends downward from the end face of the foot pedal toward the washing machine toward the slider to form a first inclined surface, and one end of the slider extends downward from the end face of the slider toward the washing machine toward the foot pedal to form a second inclined surface.

[0018] The lower end of the first inclined surface slides into the second inclined surface to drive the slider to reciprocate along the extension direction of the foot pedal.

[0019] Preferably, the upper region of the second inclined surface is provided with an inwardly recessed locking groove that matches the shape of the lower end to lock the position of the slider.

[0020] In the above scheme, by converting the vertical rotation angle of the foot pedal into a small horizontal displacement of the slider, the displacement accuracy of the lifting wheel assembly can be significantly improved, thereby more accurately controlling the guide to slide up and down along the guide and improving the reliability of the lifting wheel lifting process.

[0021] Furthermore, the washing machine also includes,

[0022] A foot pedal axle seat is fixedly installed at the bottom of the washing machine, and the foot pedal is mounted on the foot pedal axle seat via a foot pedal shaft.

[0023] Furthermore, the lifting wheel is mounted on the lifting wheel bracket via a rotating shaft, and both ends of the rotating shaft pass through the lifting wheel bracket to form the guide;

[0024] Preferably, the lifting wheel assembly includes two lifting wheel brackets, which are spaced apart on one side of the bottom of the washing machine. Each lifting wheel bracket is equipped with a lifting wheel, and the rotating shaft passes through the lifting wheel and is connected to each lifting wheel bracket.

[0025] Furthermore, the foot pedal is located between two lifting wheel brackets, and the slider has a through-hole, which is connected to each lifting wheel bracket through the rotating shaft;

[0026] The foot pedal is provided with limiting members at both ends of the foot pedal in the direction of rotation. The limiting members extend from the end face near the foot pedal toward the slider to restrict the movement of the foot pedal and the slider in the direction of rotation.

[0027] In the above solution, by providing limiting components at both ends of the foot pedal located in the direction of rotation axis extension, the left and right movement of the foot pedal and the slider in the direction of rotation axis extension can be restricted, thereby improving the reliability of the lifting wheel lifting process.

[0028] Furthermore, the limiting member is a limiting plate, and the end of the limiting plate near the washing machine is bent outward to form a flange, which is fixedly connected to the bottom wall of the washing machine.

[0029] Furthermore, the washing machine also includes,

[0030] Multiple feet are provided on the bottom of the washing machine on one side near the lifting wheel assembly;

[0031] A hidden groove is provided on one side of the bottom of the washing machine, and is recessed into the interior of the washing machine from the bottom wall of the washing machine, for accommodating the lifting wheel assembly.

[0032] Furthermore, the distance between the lowest point of the lifting wheel and the bottom of the washing machine is H1, and the distance between the lowest point of the base and the bottom of the washing machine is H2;

[0033] The washing machine has a first state and a second state. In the first state, the lower end of the first inclined surface is located in the lower region of the second inclined surface, satisfying H2 > H1. In the second state, the lower end of the first inclined surface is located in the locking groove of the second inclined surface, satisfying H2 < H1.

[0034] Furthermore, the moving wheel assembly includes,

[0035] A movable wheel bracket and a movable wheel mounted on the movable wheel bracket, wherein an elastic body is provided on the outer peripheral surface of the movable wheel to improve the friction between the movable wheel and the ground;

[0036] The elastic body is integrally formed with the movable wheel, or the elastic body is mounted on the outer peripheral surface of the movable wheel;

[0037] Preferably, the elastomer is rubber, and the washing machine is a pulsator washing machine.

[0038] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0039] The washing machine provided by the present invention, by setting the end face of the foot pedal to cooperate with the inclined end face of the slider, when the foot pedal rotates up and down in the vertical direction, the slider will reciprocate along the extension direction of the foot pedal, thereby causing the guide to slide up and down along the guide, realizing the raising or lowering of the lifting wheel relative to the ground. The moving device is simpler and the raising and lowering operation of the lifting wheel is more simplified, which not only reduces production costs but also improves the user experience.

[0040] The washing machine provided by the present invention, by setting the structure of the guide member to have an inclined extended guide groove, can more easily guide the lifting wheel assembly to move up and down, thereby simplifying the lifting motion of the lifting wheel.

[0041] The washing machine provided by the present invention can significantly improve the displacement accuracy of the lifting wheel assembly by converting the angle of vertical rotation of the foot pedal into a small stroke displacement of the slider in the horizontal direction. This allows for more precise control of the guide member's vertical sliding along the guide member, thereby improving the reliability of the lifting wheel's lifting process.

[0042] The washing machine provided by the present invention, by providing limiting members at both ends of the foot pedal located in the direction of rotation axis extension, can restrict the left and right movement of the foot pedal and the slider in the direction of rotation axis extension, thereby improving the reliability of the lifting wheel lifting process.

[0043] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0053] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0054] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0055] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0056] like Figures 1 to 4 As shown, the present invention provides a washing machine, including: a lifting wheel assembly 10 and a moving wheel assembly 30, respectively disposed on opposite sides of the bottom of the washing machine 1; the lifting wheel assembly 10 includes a lifting wheel bracket 11 and lifting wheels 12 mounted on the lifting wheel bracket 11;

[0057] At least two guide members 20 with a certain height are respectively installed at the bottom of the washing machine 1, and outwardly extending guide members are respectively installed on both sides of the lifting wheel bracket 11, and the guide members are slidably connected to the guide members 20;

[0058] The foot pedal 22 is rotatably mounted on the bottom of the washing machine in a vertical direction. One end of the foot pedal 22 is provided with a slider 222. The slider 222 is fixedly connected to the lifting wheel assembly 10. The side of the slider 222 near the foot pedal 22 is engaged with the inclined end face of the foot pedal 22.

[0059] The foot pedal 22 is controlled to rotate vertically up and down by the other end of the foot pedal 22, and then the slider 222 drives the lifting wheel assembly 10 to move back and forth along the extension direction of the foot pedal 22, and drives the guide to slide up and down along the guide 20, so as to adjust the distance between the lifting wheel 12 and the bottom of the washing machine.

[0060] Since most existing washing machines still require users to exert effort to keep the casters on the ground or suspended in the air, this can pose operational difficulties for elderly people and women with limited strength, especially when the washing machine is heavy. Therefore, this invention addresses this issue by having the end face of the foot pedal engage with the inclined end face of the slider. When the foot pedal rotates vertically up and down, the slider reciprocates along the extension direction of the foot pedal, causing the guide to slide up and down along the guide, thus raising or lowering the lifting wheels relative to the ground. This simplifies the moving device and the raising / lowering operation of the wheels, reducing production costs and improving the user experience.

[0061] It should be noted that the extension direction of the foot pedal of the present invention is determined by the installation position of the foot pedal. That is, depending on the installation position of the foot pedal, the extension direction of the foot pedal can be forward, backward, left or right, or even to the left front, right front, left rear or right rear of any point on the ground.

[0062] In some implementations, such as Figure 1 and Figure 2 As shown, the guide member 20 has a guide groove 21 on the side wall facing the lifting wheel bracket 11; the guide member 20 has a first end on the side facing the washing machine and a second end on the side facing away from the washing machine, and the guide groove 21 extends downward at an incline from the first end to the second end.

[0063] The guide is inserted into the guide groove 21 and slides up and down along the extension direction of the guide groove 21.

[0064] In the above scheme, by setting the structure of the guide member 20 to have an inclined extended guide groove 21, it is easier to guide the lifting wheel assembly 10 to move up and down, thereby simplifying the lifting motion of the lifting wheel 12.

[0065] Preferably, at least two guide members 20 with a certain height are located on both sides of the lifting wheel bracket 11 and at a position perpendicular to the moving direction of the lifting wheel assembly 10.

[0066] In some implementations, such as Figure 5 As shown, one end of the foot pedal 22 extends downward from the end face of the foot pedal 22 toward the washing machine in a direction close to the slider 222 to form a first inclined surface 2211, and one end of the slider 222 extends downward from the end face of the slider 222 toward the washing machine in a direction away from the foot pedal 22 to form a second inclined surface 2221.

[0067] The lower end 2212 of the first inclined surface 2211 is slidably engaged with the second inclined surface 2221 to drive the slider 222 to reciprocate along the extension direction of the foot pedal 22;

[0068] Preferably, such as Figure 5 As shown, the upper region of the second inclined surface 2221 is provided with an inwardly recessed locking groove 2222, which matches the shape of the lower end 2212 to lock the position of the slider 222.

[0069] In the above scheme, by converting the vertical rotation angle of the foot pedal 22 into a small horizontal displacement of the slider 222, the displacement accuracy of the lifting wheel assembly 10 can be significantly improved, thereby more accurately controlling the guide to slide up and down along the guide 20 and improving the reliability of the lifting wheel 12 lifting process.

[0070] In some implementations, such as Figure 3 As shown, the washing machine also includes,

[0071] The foot pedal axle seat 223 is fixedly installed at the bottom of the washing machine, and the foot pedal part 22 is installed on the foot pedal axle seat 223 via the foot pedal shaft 226.

[0072] In the above solution, the foot pedal 22 is fixedly installed at the bottom of the washing machine by the foot pedal axle seat 223, which can provide support for the rotation of the foot pedal 22.

[0073] In some implementations, such as Figure 3 and Figure 4 As shown, the lifting wheel 12 is mounted on the lifting wheel bracket 11 via a rotating shaft 13, and both ends of the rotating shaft 13 pass through the lifting wheel bracket 11 to form the guide.

[0074] After the two ends of the rotating shaft 13 form guides, they can be slidably connected to the guide groove 21, or directly inserted into the guide groove 21, and then move up and down along the extension direction of the guide groove 21. By using the two ends of the rotating shaft 13 passing through the lifting wheel bracket 11 as guides, the structural strength of the guides is ensured and the service life of the guides is extended.

[0075] Of course, the guide can also be a strip structure, column structure or other structure that can cooperate with the guide groove 21, which is directly set at both ends of the lifting wheel bracket 11 and extends outward.

[0076] Preferably, the lifting wheel assembly 10 includes two lifting wheel brackets 11, which are spaced apart on one side of the bottom of the washing machine. Each lifting wheel bracket 11 is equipped with a lifting wheel 12, and the rotating shaft 13 passes through the lifting wheel 12 and is connected to each lifting wheel bracket 11.

[0077] When there are two lifting wheel brackets 11, one lifting wheel 12 can be installed on each lifting wheel bracket 11. Each lifting wheel 12 can be connected by a rotating shaft 13, or they can be connected by different rotating shafts 13.

[0078] In some implementations, such as Figure 4 As shown, the foot pedal 22 is located between two lifting wheel brackets 11, and the slider 222 is provided with a shaft hole 224. The shaft hole 224 is connected to each lifting wheel bracket 11 through the rotating shaft 13.

[0079] The foot pedal 22 is provided with limiting members 225 at both ends of the extension direction of the rotation shaft 13. The limiting members 225 extend from the end face near the foot pedal 22 toward the slider 222 to restrict the movement of the foot pedal 22 and the slider 222 in the extension direction of the rotation shaft 13.

[0080] In the above solution, by providing limiting members 225 at both ends of the foot pedal 22 located in the extension direction of the rotating shaft 13, the left and right movement of the foot pedal 22 and the slider 222 in the extension direction of the rotating shaft 13 can be restricted, thereby improving the reliability of the lifting wheel 12 lifting process.

[0081] In some implementations, such as Figure 4 As shown, the limiting member 225 is a limiting plate. The end of the limiting plate near the washing machine is bent outward to form a flange 2251. The flange 2251 is fixedly connected to the bottom wall 26 of the washing machine.

[0082] The flange 2251 structure ensures the stability of the installation position of the limiting member 225 and improves the ability to restrict the left and right movement of the foot pedal 22 and the slider 222 in the extension direction of the rotation axis 13.

[0083] In some implementations, such as Figure 2 As shown, the washing machine also includes a plurality of base feet 24, which are disposed on the bottom of the washing machine near the lifting wheel assembly 10.

[0084] A hidden groove 25 is provided on one side of the bottom of the washing machine, and is recessed into the interior of the washing machine from the bottom wall 26 of the washing machine, for accommodating the lifting wheel assembly 10.

[0085] In some embodiments, the distance between the lowest point of the lifting wheel 12 and the bottom of the washing machine is H1, and the distance between the lowest point of the base 24 and the bottom of the washing machine is H2;

[0086] The washing machine has a first state and a second state. In the first state, the lower end 2212 of the first inclined surface 2211 is located in the lower region of the second inclined surface 2221, satisfying H2 > H1. In the second state, the lower end 2212 of the first inclined surface 2211 is located in the locking groove 2222 of the second inclined surface 2221, satisfying H2 < H1.

[0087] When the washing machine needs to be moved, the other end of the foot pedal 22 is rotated vertically downwards (i.e., towards the ground), causing the lower end 2212 of the first inclined surface 2211 to slide upwards along the second inclined surface 2221, pushing the slider 222 away from the first inclined surface 2211. This causes the guide to move downwards along the guide 20, gradually increasing the distance between the lifting wheel 12 and the bottom of the washing machine, so that the lifting wheel 12 is supported on the ground, raising one side of the washing machine to a certain height. At this time, the lower end 2212 is engaged in the locking groove 2222, meaning the washing machine is in the second state. The wheels in the lifting wheel assembly 10 and the moving wheel assembly 30 rotate simultaneously to move the washing machine, making the movement of the washing machine more convenient, quick, time-saving, and labor-saving.

[0088] When the washing machine moves to the predetermined position, the other end of the foot pedal 22 rotates vertically upward (i.e., rotates away from the ground), causing the lower end 2212 of the first inclined surface 2211 to disengage from the locking groove 2222 and slide down the lower area along the second inclined surface 2221. This pushes the slider 222 to move closer to the first inclined surface 2211, causing the guide to move upward along the guide 20. This gradually reduces the distance between the lifting wheel 12 and the bottom of the washing machine, suspending the lifting wheel 12 in the air. Then, the bottom foot 24 touches the ground to support the washing machine, thus placing the washing machine in the first state and preventing it from moving during operation.

[0089] In some implementations, such as Figure 2 As shown, the moving wheel assembly 30 includes,

[0090] The moving wheel bracket 31 and the moving wheel 32 mounted on the moving wheel bracket 31 are provided with an elastic body 33 on the outer peripheral surface of the moving wheel 32 to improve the friction between the moving wheel 32 and the ground;

[0091] The elastic body 33 is integrally formed with the movable wheel 32, or the elastic body 33 is mounted on the outer peripheral surface of the movable wheel 32;

[0092] Preferably, the elastomer 33 is rubber, and the washing machine is a pulsator washing machine.

[0093] It is understood that the movable wheel 32 can be a fixed wheel, a swivel wheel, a caster, or other wheels that enable the washing machine to move. The movable wheel 32 can be connected to the movable wheel bracket 31 through a connecting shaft.

[0094] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
