A multi-barrel drum washing machine barrel connection device and a multi-barrel drum washing machine

Abstract

This utility model discloses a tub-to-tub connection device for a multi-tub drum washing machine and the multi-tub drum washing machine itself. The tub-to-tub connection device includes a parallel upper mounting plane and a lower mounting plane. A vertical plane perpendicular to both the upper and lower mounting planes connects them. The upper mounting plane has several spaced-apart upper light holes at its end furthest from the vertical plane, and the lower mounting plane also has several spaced-apart lower light holes at its end furthest from the vertical plane. Two rows of light holes are formed along the length of the vertical plane, each row containing several spaced-apart light holes. This utility model effectively solves the problem that washing machines can only achieve vertical and horizontal movement limits during transportation, lacking forward and backward movement limits, while simultaneously achieving tub-to-tub connection.

It can realize the connection between the drums and effectively solve the problem that the washing machine can only realize the vertical and horizontal limit during transportation, but lacks the front and back direction limit.

[0004] This utility model adopts the following technical solution: a connecting device between drums of a multi-drum washing machine, including an upper mounting plane and a lower mounting plane that are parallel to each other. A vertical plane perpendicular to the upper mounting plane and the lower mounting plane is connected between the upper mounting plane and the lower mounting plane. A plurality of spaced-apart upper light holes are formed at the end of the upper mounting plane away from the vertical plane. A plurality of spaced-apart lower light holes are also formed at the end of the lower mounting plane away from the vertical plane. Two rows of light hole groups are formed along the length direction of the vertical plane. Each row of light hole groups includes a plurality of spaced-apart light holes.

[0005] Furthermore, a number of flanged threaded holes spaced apart vertically are formed on the vertical plane between the two rows of light holes.

[0006] Furthermore, the flanged threaded hole is machined with internal threads.

The left tub has an upper left screw hole at a position opposite to the upper light hole on the left side, a lower left screw hole at a position opposite to the lower light hole on the left side, and a left screw hole at a position opposite to the light hole group on the left side. The right tub has an upper right screw hole at a position opposite to the upper light hole on the right side, a lower right screw hole at a position opposite to the lower light hole on the right side, and a right screw hole at a position opposite to the light hole group on the right side.

[0015] Figure 3 This is a schematic diagram showing the installation of the inter-tub connection device of the multi-tub drum washing machine of this utility model on the left and right tubs. Detailed implementation method:

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] This utility model relates to a connecting device between the drums of a multi-drum washing machine, comprising an upper mounting plane 1 and a lower mounting plane 2 that are parallel to each other. A vertical plane 3, perpendicular to both the upper mounting plane 1 and the lower mounting plane 2, connects the two surfaces. A plurality of spaced-apart upper light holes 10 are formed at the end of the upper mounting plane 1 furthest from the vertical plane 3, and a plurality of spaced-apart lower light holes 20 are also formed at the end of the lower mounting plane 2 furthest from the vertical plane 3.

[0018] Two rows of aperture groups 30 are formed along the length of the vertical plane 3, each row containing several spaced-apart apertures. Several vertically spaced, flanged threaded holes 31 are formed between the two rows of aperture groups 30 on the vertical plane 3. The edges of the flanged threaded holes 31 are reinforced by a flange (extrusion curling) process, and internal threads are machined within the holes. The flange structure significantly enhances the load-bearing capacity and connection strength of the threads, and effectively prevents the risk of thread stripping in thin sheet materials, making it suitable for bolt fastening requirements with larger loads.

[0019] The multi-tub drum washing machine includes a left tub 4 and a right tub 5 arranged at intervals. The left tub 4 has an upper left screw hole 40 opposite to the upper light-emitting hole 10 on the left side, a lower left screw hole (not shown) opposite to the lower light-emitting hole 20 on the left side, and a left screw hole 41 opposite to the light-emitting hole group 30 on the left side. The right tub 5 has an upper right screw hole (not shown) opposite to the upper light-emitting hole 10 on the right side, a lower right screw hole (not shown) opposite to the lower light-emitting hole 20 on the right side, and a right screw hole (not shown) opposite to the light-emitting hole group 30 on the right side.

[0020] This invention installs the tub-to-tub connection device onto the left tub 4 and right tub 5 by screwing bolts into the upper smooth hole 10 and the upper left and upper right screw holes, screwing bolts into the lower smooth hole 20 and the lower left and lower right screw holes, and screwing bolts into the smooth hole group 30 and the left and right screw holes. Short transport bolts are then screwed into the flanged threaded hole 31 to install the left tub 4 and right tub 5 together with the washing machine cabinet, thereby restricting the forward and backward displacement of the left tub 4 and right tub 5.

[0021] This utility model relates to a multi-tub drum washing machine tub connection device that not only achieves a reliable connection between the tubs, but also features a specially designed flanged threaded hole in the middle of its structure. By installing specially made short transport bolts at the flanged threaded hole, effective front-to-back constraints can be applied to the tubs during equipment transportation to prevent displacement.

[0022] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
