Referring to Figures 1 to 5, the present invention provides a washing machine comprising a base 3 on which a roller 1 and a support body 2 are mounted, and the rolling outer peripheral surface of the roller 1 is provided a tooth groove, the support body is provided with a tooth groove 4, a first direction force is applied to the washing machine, the roller 1 is freely rotated, and the washing machine is moved to apply a force in a second direction opposite to the first direction to the washing machine, The teeth of the roller 1 mesh with the slots 4 of the support body 2 and are fixed to support the fixed washing machine.

In the present invention, the teeth of the roller 1 are engaged with and fixed to the slots 4 of the support body 2, and the support body also contacts the ground to fix the washing machine together with the rollers. The support body and the roller support the fixed washing machine, and the washing machine is fixed only by the roller, which increases the contact area between the washing machine and the ground, increases the friction between the washing machine and the ground, and is beneficial to the stability of the washing machine.

As an embodiment of the present invention, the support body 2 is provided with a locking portion near the rolling outer circumferential surface of the roller 1, and the tooth groove 4 is disposed on the locking portion, and the second direction force is applied to the washing machine. The teeth on the roller 1 are meshed and fixed with the slots 4, and a force in the first direction opposite to the second direction is applied to the washing machine. The teeth of the roller 1 are disengaged from the slots 4 and can be freely rotated, thereby facilitating the movement of the washing machine. Wherein, the locking portion is not limited to one, and preferably a plurality of locking portions are provided, thereby facilitating the locking of the roller by the supporting body.

With the above arrangement, when the washing machine needs to move the position, the user applies sufficient force in the first direction, the roller of the washing machine can freely roll out of the tooth groove 4, thereby facilitating the movement of the washing machine, and the washing machine needs to move to the target position. In the fixed position, it is only necessary to apply a force in the second direction opposite to the first direction to the washing machine, and the washing machine can move a small distance because the roller and the locking portion are engaged in the washing machine to be locked and fixed. The invention solves the problem that the existing washing machine is difficult to move.

As an embodiment of the present invention, the support body 2 is a belt-like structure, one end of which is fixed to the base 3, and the other end contacts the roller 1 and is provided with a tooth groove 4 to form the locking portion. Of course, the tooth groove 4 of the support body 2 in the present invention is not limited to being disposed at the end portion, and may be disposed at a position in the middle of the belt-like structure that can contact the surface of the roller 1. In the present invention, the locking portion is not limited to one place, and a plurality of locking portions may be provided to enhance the locking effect.

As an embodiment of the present invention, the support structure 2 of the strip structure is disposed around the rolling outer peripheral surface of the roller 1, and the two ends thereof are respectively fixed on the base 3 on both sides of the rolling direction of the roller 1, and the strip structure is The bottom of the support body 2 is provided with a relief opening corresponding to the roller 1, and the roller can protrude from the support body and contact with the ground, and the inner surface of the other position of the support body of the strip structure has contact with the rolling outer peripheral surface of the roller 1. The surface of the contact is provided with teeth on the surface to form a locking portion. In the structural arrangement, since the roller 1 is disposed inside the space surrounded by the support body 2 of the belt structure, space saving is facilitated. The base 3 has a compact structure and a refined appearance.

As an embodiment of the present invention, one end of the support body 2 of the belt-like structure is fixed to the base 3 on one side of the roller 1, and the other end is a free end, and the free end is extended from the bottom of the roller 1 to the other of the roller 1. On the side, the corresponding roller 1 on the bottom of the support body 2 is provided with a relief port, and the roller protrudes from the escape port to be in contact with the ground, and the support body 2 is disposed on a surface between the escape port and the free end. The tooth groove 4 forms the aforementioned locking portion. In this embodiment, the locking portion is provided on one side of the free end to facilitate actual kneading and fixing. For example, when the roller moves in the second direction, the teeth on the roller mesh with the slots on the support body, and the free end will tilt toward the ground under the action of the roller, so that the support body and the roller will support the fixed washing machine together. On the other hand, because the teeth on the roller will contact the ground, the gear teeth will be damaged under long-term support. Therefore, the locking portion of the support body is disposed on the roller side near the bottom of the roller or close to At the bottom of the roller and in contact with the surface of the roller, the roller will partially engage into the slot of the support body, and the tooth groove of the support body has the function of protecting the teeth of the roller. Of course, in the present invention, after the roller is engaged with the support body, the free end of the support body also contacts the ground to increase the friction between the washing machine and the ground, which is beneficial to the stability of the washing machine.

In order to make the structure in the above embodiment more reasonable and beautiful, further, the support body 2 is a C-type strip structure, and the upper end of the C-type strip structure is connected to the bottom stage 3, and the lower end of the C-type strip structure is The free end, the roller 1 is disposed in the C-belt structure, and the bottom of the C-belt structure is provided with a relief opening corresponding to the roller 1, and the C-shaped strip structure is disposed from the escape port to the upper surface of the free end. The tooth groove 4 described above forms the locking portion. In this embodiment, it is more reasonable to provide the locking portion on the free end side of the C-shaped structure than to be disposed at other positions. In the embodiment, the support body 2 has a certain elasticity, as shown in FIG. Then, when the roller 1 moves in the second direction, that is, clockwise rotation on the figure, the teeth on the roller mesh with the tooth groove 4, and the teeth act on the free end of the C-shaped belt structure to promote the downward movement thereof, so as to support The bottom of the body forms a planar structure, which is arranged to facilitate the support body 2 and the roller 1 to jointly support the fixed washing machine. On the other hand, the tooth groove 4 on the free end has a tooth groove 4 which is in direct contact with the teeth of the roller 1, and a tooth groove which is close to the roller 1 but has not yet contacted, when the roller 1 moves in the second direction, The teeth on the roller 1 first mesh with the contact slots 4. Further, since the free ends have a certain elasticity, the free ends will contact the rollers after the teeth on the rollers 1 are in contact with the contactable slots 4. When the direction is close to a small distance, the teeth will further mesh with the initially uncontacted slots 4 to further increase the kneading stability of the two, which facilitates the tight engagement of the roller 1 with the locking portion.

In the present invention, the first direction force is applied to the washing machine, and the washing machine moves in the first direction, and the second direction force is applied to the washing machine to lock the washing machine. In the present invention, the teeth on the roller 1 are inclined, and/or the slots 4 on the support 2 are inclined. For example, the gear teeth on the roller are inclined to one side, and the tooth grooves on the support body may be inclined or not, when the inclined teeth on the roller move toward the tooth grooves of the support body, The inclined teeth will enter the slots and engage the slots.

As an embodiment of the present invention, the teeth on the roller 1 and the slots 4 on the support 2 are both inclined, and the direction of inclination of the slots 4 is opposite to the direction in which the teeth are inclined. When the teeth on the roller 1 move toward the slots 4 of the locking portion, the teeth of the roller 1 are engaged with the slots 4 of the locking portion, and when the teeth on the roller 1 move away from the slot 4, the wheel The tooth is separated from the tooth groove 4 to drive the washing machine to move. In the present invention, the cogging and the tooth teeth are inclined to face each other, and the effect is better, which is a preferred technical solution.

In order to further promote the kneading stability of the roller 1 and the locking portion, in order to achieve the technical effect of being fixed together after the engagement, it is preferable that the tooth groove 4 of the support body 2 has a narrowing section smaller than the tooth width. With this arrangement, the teeth and the slots 4 can be tightly meshed to form an integral body. Further, the tooth groove 4 is made of a material having less elasticity, and the teeth are compressible and kneaded in the narrowed section of the tooth groove 4, and the kneading fixation between the two is similar to the welding and fixing together. The higher degree of bonding reduces the risk of vibrations in the operation of the washing machine causing the teeth of the rollers to disengage from the gullets.

As an embodiment of the present invention, the tooth groove 4 on the support body 2 is disposed near the bottom of the roller 1 in the involute direction of the rolling outer peripheral surface of the roller 1. This structural arrangement is intended to improve the accuracy of the engagement and the reliability of the engagement.

Based on the above embodiments, in the embodiment, the bottom of the support body 2 is a planar structure suitable for stabilization. The bottom of the support body 2 is arranged in a planar structure. After the roller 1 is engaged with the support body 2, after the roller 1 and the support body 2 are integrally fixed, the bottom of the support body 2 can be smoothly supported on the ground. Further, the support body 2 has a support portion that is in contact with the ground, and a side of the support portion that contacts the ground is a planar structure. Preferably, a side of the support portion that contacts the ground is further provided with a non-slip layer. The layer setting is beneficial to ensure the stability of the washing machine during the operation of the washing machine. Of course, the side of the support portion of the support that contacts the ground may be provided as a rough surface structure to increase the frictional force with the ground.

As an embodiment of the present invention, the four corners of the bottom plate 3 of the washing machine respectively have a matching roller 1 and a supporting body 2, and the four rollers 1 and the supporting body 2 are disposed at the same relative position, and are fixed to the washing machine in a non-rotatable manner. On the base 3, through the structure, the movable direction of the washing machine is fixed, and the user can rotate the washing machine directionalally while moving the washing machine, and then push the washing machine to the side, when the washing machine needs to be fixed, The washing machine can be fixed by simply retracting a small distance to the opposite side.

Of course, in the present invention, the mutually cooperating roller 1 and the support body 2 can also be rotatably fixed on the washing machine base 3. Specifically, a roller 1 and a supporting support are respectively arranged at the four corners of the bottom plate 3 of the washing machine. Body 2, the relative position of the roller 1 and the corresponding support body 2 is fixed, but the direction between the roller and the support body can be changed relative to the rotation of the washing machine base. At this time, in the process of moving the washing machine specifically, it is necessary to first rotate the roller 1 and Corresponding to the position of the support body 2, and then pushing to realize the movement of the washing machine, which is fixed on the bottom plate of the washing machine with respect to the roller and the support body, the present embodiment has high flexibility and does not need to be moved when the washing machine is needed. Move the washing machine position before pushing the washing machine, but you need to change the direction of the four rollers first. Both technical solutions have their own advantages and disadvantages.

In the present invention, the first direction is that the washing machine is rearward or forward or from front to back, and the rolling outer peripheral surface of the roller is disposed toward the first direction. The rolling outer circumferential surface of the roller 1 is disposed toward the front-rear direction of the washing machine, and the tooth groove 4 of the support body 2 is disposed at a position on the rear side of the roller 1. At the same time, the tooth grooves are opposite to the direction in which the teeth of the roller are inclined, and the inclination directions of the two are opposite. Through this structure setting, when the washing machine is in the washing process, vibration in the front-rear direction is generated, and the direction in which the roller and the supporting body are meshed and fixed is also in the front-rear direction of the washing machine, so the roller and the supporting body provide resistance to the washing machine to prevent the washing machine from vibrating. serious. On the other hand, after the teeth of the roller mesh with the slots on the support body, the support body will contact the ground under the action of the roller, thereby further reducing the vibration of the washing machine. When it is necessary to move the washing machine, it is necessary to rotate the washing machine, and then push the washing machine to the target position from the back to the front. It should be noted that in the present invention, the force provided to the washing machine needs to be large enough to make the teeth of the roller disengage. When the tooth groove of the support body rotates counterclockwise as shown in FIG. 4, the teeth of the roller 1 can be disengaged from the tooth groove 4, the roller is unlocked, and the washing machine can be pushed to the target position. It should be noted that, in the present invention, the front side, the rear side, the front, the rear, and the like of the washing machine are relative to the front side and the rear side of the washing machine, and the front side of the washing machine refers to the washing operation, and the washing machine is close to the operator. On one side, for example, the front side of the drum washing machine is the side on which the door cover is provided, and the front side of the pulsator washing machine refers to the side on which the inner surface of the upper cover faces after the upper cover is opened. Specifically, the roller is disposed in a first direction, the washing machine includes a box, the box has a front panel and a rear panel disposed opposite to the front panel, and the first direction is a front panel facing the rear panel The direction.

In each of the above embodiments, the roller and the support body are separately provided. Of course, the roller and the support body may also be integrally provided. Even the support body can be disposed inside the roller. Specifically, the roller is connected to the bottom plate of the washing machine through a rotating shaft. The rotating shaft protrudes radially from the roller with a locking portion, and the locking portion is provided with a tooth or a tooth groove. The rolling outer peripheral surface of the roller is not provided with gear teeth, but is internally concentrically provided with inner teeth surrounding the locking portion. Similarly, the tilting direction of the gear teeth of the locking portion and the inner teeth of the roller The tilt direction is set oppositely. The structural design can also achieve the required technical effects.

In the above solution, the support body can be integrally provided on the bottom of the base. At this time, the support body and the bottom plate are made of the same hard material. In order to facilitate the relatively stable engagement between the gear teeth of the roller and the cogging on the support body, The material of the support is preferably a material having a certain elasticity. In the present invention, preferably, the support is mounted on the bottom of the washing machine.

When the washing machine of the invention needs to move the position, the washing machine can be pushed only by rotating the position of the washing machine, and the washing machine can be fixed only by moving the washing machine to the target position in a reverse direction, thereby solving the present problem. There is a problem with the difficulty of moving the washing machine.

It should be noted that the technical solutions defined by the above embodiments of the present invention may be implemented separately or in combination with each other.
