Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and examples.

It should be noted that in the description of the present invention, the terms of direction or positional relationship indicated by the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, which are merely for convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Referring to fig. 1 to 5, there is shown an embodiment of a dishwasher of the present invention, which includes a tub 100, a rack body 200, and a position adjusting assembly. The rack body 200 is disposed in the inner tub 100 of the dishwasher for placing dishes to be washed, etc. A shower 500 is provided in the inner container 100 for washing the dishes to be washed. The position adjusting assembly is fixedly arranged in the dish washing machine, and the height of the four corners of the shelf body 200 can be respectively adjusted relative to the horizontal plane through the position adjusting assembly.

According to the dish washing machine, the height of the four corners of the shelf body 200 can be respectively adjusted by arranging the position adjusting component, so that the shelf body 200 can change the spatial position in the dish washing machine, different inclination angles are realized, the shelf body can be positioned on a specific inclined plane, the inclination angles can also be changed ceaselessly, further, tableware can be washed in multiple directions and multiple angles, and the cleaning effect and efficiency of the dish washing machine are improved; meanwhile, when drying, the inclination angle of the shelf body 200 is changed through the position adjusting assembly, so that water stains in the tableware flow out of the tableware more quickly, and the drying efficiency is improved.

Specifically, referring to fig. 3, the position adjustment assembly includes four elevating mechanisms 300, and the elevating mechanisms 300 are respectively abutted with four corners of the shelf body 200. In this embodiment, the elevating mechanism 300 is provided at the lower side of the shelf body 200.

The specific structure of the lifting mechanism 300 is shown in fig. 4 and 5, and includes a housing 310, a lifting lever 320, a worm wheel 330 and a worm 340, and a driving member (not shown). The housing 310 is fixed to the tub 100 of the dishwasher. The elevating bar 320 vertically passes through the housing 310, and the top end thereof abuts against the bottom of the shelf body 200. The worm wheel 330 is disposed in the housing 310, and the worm wheel 330 is sleeved on the lifting rod 320 and is in threaded connection with the lifting rod 320, that is, the lifting rod 320 is a screw structure. The worm 340 is horizontally and rotatably disposed on the housing 310, and the worm 340 is engaged with the worm wheel 330. A drive member, preferably a motor, is drivingly connected to the worm 340 for driving rotation of the worm 340, each drive member being individually controlled by the control system of the dishwasher.

The operating principle of the lifting mechanism 300 is as follows: the driving member drives the worm 340 to rotate, and the worm 340 and the worm wheel 330 are in transmission fit to drive the worm wheel 330 to rotate. The worm wheel 330 can only rotate around its axis by the limit action of the housing 310, and cannot move up and down. When the worm wheel 330 rotates, the lifting rod 320 is driven to rotate and move up and down along the axial direction, so as to realize the lifting function of the lifting mechanism 300. Wherein, the ascending or descending state of the lifting rod 320 can be changed by changing the rotation direction of the worm 340. In other embodiments, the lifting mechanism 300 may be implemented by other structures, such as a rack disposed on the lifting rod 320, a rack and pinion mechanism for lifting, or a hydraulic lifting mechanism 300.

In this embodiment, the front side and the rear side of the shelf body 200 are respectively provided with a support rod 400, the top end of the lifting rod 320 is provided with a support member 350, and the support rod 400 is supported on the support member 350. The top surface of the supporting member 350 is provided with an arc-shaped groove along the length direction of the supporting rod 400 for accommodating the supporting rod 400, and the supporting rod 400 can be positioned through the arc-shaped groove to prevent the falling off of the supporting member 350 in the lifting process of the shelf body 200. In other embodiments, the support bars 400 may be disposed on the left and right sides of the shelf body 200, which will not be described herein.

The inner container 100 of the dishwasher is provided with slide rails 110 at both sides thereof, the support rod 400 is provided with pulleys 410 at both ends thereof, and when the rack body 200 is located at the lowest position, the pulleys 410 can be slidably supported on the slide rails 110. The rack body 200 is drawably provided in the dishwasher through the pulley 410 and the slide rail 110. In this embodiment, the lowest point of the arc-shaped slot of the supporting member 350 at the top end of the lifting rod 320 is lower than the upper surface of the sliding rail 110, so that the shelf body 200 can be placed on the sliding rail 110 when the lifting mechanism 300 is not in operation.

According to the dishwasher, the shelf body 200 is arranged right above the sprayer 500, the four lifting mechanisms 300 can be lifted and lowered independently by the dishwasher control system, and the angle of the shelf body 200 is adjusted according to a set working mode. As shown in fig. 6a, the shelf body 200 can be tilted to the left by adjusting the two lifting mechanisms on the right side to synchronously lift and keeping the two lifting mechanisms on the left side still; as shown in fig. 6b, the rack body 200 can be tilted to the right by adjusting the left lifting mechanism to synchronously lift and the right lifting mechanism to be stationary. Similarly, as shown in fig. 6c and 6d, the front and rear inclination of the shelf body 200 is achieved by adjusting the lifting mechanisms at the front and rear sides. Fig. 6a to 6d shown in this embodiment are four common tilting modes of the shelf body 200, and tilting is performed based on one side, and since the four lifting mechanisms can be controlled independently, there are other lifting combination forms, so that the shelf body 200 forms different tilting angles, for example, by adjusting two lifting mechanisms on a diagonal line to lift one by one, the shelf body can be adjusted to tilt with one of the four corners as a fulcrum. Therefore, the inclination angle of the shelf body 200 can be adjusted according to different cleaning modes and drying modes, so that the tableware on the shelf body 200 can be better contacted with water in the cleaning process, and the cleaning effect is improved; so that the tableware 200 on the shelf body can flow out the residual water stain more quickly in the drying process, and the drying efficiency is improved.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
