Referring to fig. 1 to 3, fig. 1 is a schematic structural view of a drum washing machine according to an embodiment of the present invention; FIG. 2 is a schematic structural diagram of a drum hoop of a drum washing machine according to an embodiment of the present invention; fig. 3 is an axial schematic view of an enlarged view of a portion a of fig. 2. Referring to fig. 1 to 3, the drum washing machine includes an inner tub 1 and a band 2 disposed around an outer wall of the inner tub 1. The barrel band 2 includes a plurality of band pieces 21 and a stirrup 22 provided between the band pieces 21. The stirrup 22 is provided with a bend 221 in the radial direction of the inner cylinder 1 so that the circumferential dimension of the collar 2 can be enlarged by bending deformation of the bend 221 when the inner cylinder 1 is rotated, and the stirrup 22 is in contact with the outer wall of the inner cylinder 1 when assembled.
The cylindrical hoop 2 is composed of the hoop pieces 21 and the hoop ribs 22 between the hoop pieces 21, the hoop ribs 22 are provided with the bends 221, the cylindrical hoop 2 has certain elasticity, when the inner cylinder 1 expands outwards due to centrifugal force generated by high-speed rotation, the cylindrical hoop 2 sleeved on the inner cylinder 1 expands the circumferential size through bending deformation of the bends 221, the phenomenon that the cylindrical hoop 2 breaks due to too large tensile deformation of the cylindrical hoop 2 in the background art is avoided, the strength and the universality of the cylindrical hoop 2 are improved, and the service life of the cylindrical hoop 2 is prolonged.
In addition, in the process of producing and testing the inner barrel 2 by the inventor, because the rotating speed of the inner barrel 2 is very high, the inner barrel 2 is cracked due to huge centrifugal force, scattered inner barrel material sheets puncture the outer barrel of the washing machine to hurt experimenters, and the damage of inner barrel cracking to users is very large. In the embodiment of the invention, when the inner cylinder 1 is exploded due to outward expansion of centrifugal force generated by high-speed rotation, the cylinder hoop 2 sleeved on the inner cylinder can absorb kinetic energy generated by explosion through bending deformation, so that the phenomenon that a high-speed material sheet penetrates through a machine body to hurt people after the inner cylinder 1 is exploded is avoided, and the safety of the inner cylinder is greatly improved.
It will be understood that although only one hoop 2 is disposed outside the inner drum 1 of the drum washing machine in the above embodiment, this is not a limitation to the number of the arranged hoops 2, and two or three hoops 2 may be disposed uniformly along the axial direction of the inner drum 1. The technical personnel in the field can reasonably select the number of the barrel hoops 2 according to actual conditions and needs, and the strength of the inner barrel 1 can be ensured on the basis that the normal work of the inner barrel 1 is not influenced.
Furthermore, it will be understood that although the stirrup 22 is provided with only one bend 221 along the radial direction of the inner cylinder 1 in the above embodiments, this is not a limitation on the bend 221 of the stirrup 22, for example, the stirrup 22 may be provided with a plurality of bends 221 along the radial direction of the inner cylinder 1, forming a wave-shaped structure, etc. Those skilled in the art can set the number of the bends 221 of the stirrup 22 according to practical conditions and needs, as long as the stirrup 22 can be bent and deformed in a state of rotating the inner tube 1, so that the circumferential dimension of the tube hoop 2 is increased appropriately.
Preferably, the diameter of the band 2 is slightly smaller than the diameter of the inner barrel 1 in the normal relaxed state. When the barrel hoop 2 is sleeved on the inner barrel 1, the stirrup 22 generates certain elastic deformation, and even if the barrel hoop 2 generates certain deformation, the generated elastic force plays a certain preloading role, so that the barrel hoop 2 can be fixed on the inner barrel 1 and can be well contacted.
As shown in fig. 4, fig. 4 is an axial schematic view of a hoop on a drum hoop of a drum washing machine according to an embodiment of the present invention. Referring to fig. 4, the bend 221 is a structure recessed inward in the radial direction of the inner cylinder 1, and in an assembled state, the bottom end of the bend 221 is in contact with the outer wall of the inner cylinder 1. Through such setting, when inner tube 1 outwards expands because high-speed rotatory centrifugal force that produces, the barrel hoop 2 of cover on inner tube 1 takes place elastic deformation through stirrup 22, thereby the elastic force that deformation produced inwards extrudees inner tube 1 and has offset some centrifugal force that acts on inner tube 1, the deformation of inner tube 1 has been reduced, the phenomenon that inner tube 1 explodes because of the rotational speed is too big has been reduced, the tablet that inner tube 1 explodes the production because of the rotational speed is too big simultaneously has also been avoided punctureing the organism and has been hindered the user, the life and the security of inner tube 1 have been improved.
It will be understood that the bend 221 may also be a structure protruding outward in the radial direction of the inner cylinder 1, or a wave-shaped structure formed by continuously recessing and protruding in the radial direction of the inner cylinder 1. The structure of the bend 221 can be set reasonably by those skilled in the art according to actual conditions and needs.
Preferably, the bend 221 includes a plurality of bending segments along the axial direction of the inner barrel 1, the plurality of bending segments are disposed at intervals, and the plurality of bending segments are not connected to each other. Avoid under extreme operating condition (under the high-speed rotatory state of inner tube 1 promptly), the barrel hoop 2 because inner tube 1 outwards expands and takes place too much tensile deformation and lead to cracked phenomenon, set up every 221 of bending into a plurality of sections of bending that set up including the axial interval along inner tube 1 for barrel hoop 2 makes stirrup 22 take place bending deformation more easily, thereby reduces the degree that barrel hoop 2 takes place tensile deformation, prolongs the life of barrel hoop 2.
It is understood that although the plurality of bending segments are not connected in the above embodiments, one skilled in the art can arrange the plurality of bending segments to be connected to each other according to actual conditions and needs, so as to increase the strength of the stirrup 22.
Preferably, the bend 221 includes a first recessed surface 2211 and a second recessed surface 2212, and the first recessed surface 2211 and the second recessed surface 2212 are symmetrically arranged. As an example, in the case that the cylinder band 2 is horizontally spread, the cross section of the structure formed by the first concave surface 2211, the second concave surface 2212 and the plane of the cylinder band 2 is an isosceles triangle. Wherein the first and second concave surfaces 2211 and 2212 are two legs of an isosceles triangle. Through such setting, can guarantee that stirrup 22 atress is even to and the effort that transmits the section of thick bamboo hoop 2 of stirrup 22 both sides through stirrup 22 is even, guarantees the reliability of section of thick bamboo hoop 2 in the course of the work.
With continued reference to fig. 4, the junction of first recessed surface 2211 and second recessed surface 2212 is provided with a first transition structure 2213. As an example, the first transition structure 2213 is a rounded chamfer structure. Because the stirrup 22 can directly contact the outer surface of the inner cylinder 1, the corner at the joint is set to be a round chamfer structure, so that the surface of the inner cylinder 1 can be prevented from being scratched by the cylinder hoop 2, and the processing difficulty can be reduced.
Preferably, the second transition structure 2214 is disposed at the connection between the first concave surface 2211 and the cylinder hoop 2 and at the connection between the second concave surface 2212 and the cylinder hoop 2. Illustratively, the second transition structure 2214 is a rounded chamfer structure identical to the first transition structure 2213, and the diameters of all three rounded chamfer structures are identical. By providing the second transition structure 2214, stress concentration at the connection of the first concave surface 2211 and the band 2 and at the connection of the second concave surface 2212 and the band 2 can be reduced.
It is understood that, although the bending part 221 described in the above embodiment includes the first concave surface 2211 and the second concave surface 2212, and the cross section of the structure formed by the first concave surface 2211, the second concave surface 2212 and the plane of the cylindrical hoop 2 is an isosceles triangle in the case that the cylindrical hoop 2 is horizontally unfolded, this is not a limitation to the bending part 221, and the bending part 221 may be provided as an arc surface curved in the radial direction of the inner cylinder 1, or a W-shaped surface curved in the radial direction of the inner cylinder 1, or the like. The bending part 221 may be appropriately provided by those skilled in the art according to actual conditions and needs, as long as the provided bending part 221 can generate elastic force by bending deformation thereof to appropriately increase the circumferential dimension of the cylindrical band 2.
As shown in fig. 3 and 5, wherein fig. 5 is a schematic structural view of a first hoop sheet of a drum hoop of a drum washing machine according to an embodiment of the present invention. Referring to fig. 3 to 5, a first hoop sheet 23 and a second hoop sheet 24 are respectively disposed at two ends of the cylindrical hoop 2, and the cylindrical hoop 2 encircles the outer wall of the inner cylinder 1 through the connection of the first hoop sheet 23 and the second hoop sheet 24. The first cuff piece 23 and the second cuff piece 24 are overlapped with each other and fixedly connected by a fastener, and in the connected state, the second cuff piece 24 is positioned inside the first cuff piece 23.
In order to ensure the connection availability and reliability of the first band piece 23 and the second band piece 24, the height of the connection between the first concave surface 2211 adjacent to the bend 221 of the second band piece 24 and the barrel band 2 is lower than that of the connection between the second concave surface 2212 and the barrel band 2, and the height difference is equal to the thickness of the barrel band 2. With this arrangement, it can be ensured that the lowermost ends of all the stirrups 22 are on the same circle after the mounting of the tubular hoop 2 on the inner tube 1, so that the stirrups 22 have good contact with the inner tube 1.
Preferably, the stirrups 22 are uniformly distributed on the tubular hoop 2. The parameters (i.e., the depth of the bend 221, the diameter of the rounded chamfer structure at the junction of the first and second recessed surfaces 2211 and 2212 of the bend 221, and the junction with the cylindrical collar 2, respectively, etc.) and the number of the stirrups 22 are determined by an optimization algorithm according to the parameters such as the diameter of the inner cylinder 1, the rotation speed, and the material properties.
As shown in fig. 6, fig. 6 is a schematic connection diagram of a first hoop sheet and a second hoop sheet of a drum hoop of a drum washing machine according to an embodiment of the present invention. Referring to fig. 6, different marks are provided on the first band piece 23 and the second band piece 24 in order to determine the installation positions of the first band piece 23 and the second band piece 24. As an example, the first strap 23 is provided with a chamfer cut 231, and the second strap 24 is provided with a groove cut 241. This arrangement is provided to facilitate the operator or machine to distinguish between the inner side and the outer side of the two hoop sheets when assembling the processed elongated blanks into the hoop 2.
It will be appreciated that it is also possible to provide only the first strap piece 23 or the second strap piece 24 with markings to distinguish the mounting positions of the two strap pieces. The skilled person can reasonably set the marks on the first cuff sheet 23 and/or the second cuff sheet 24 according to the actual situation and needs, as long as the first cuff sheet 23 and the second cuff sheet 24 can be distinguished.
With continued reference to FIG. 6, the first strap 23 is fixedly connected to the second strap 24 by five fasteners, which are distributed in a diamond shape and located at the four vertices and the center point of the diamond shape. The cost, performance, assembly and other aspects of the effective connection mode are comprehensively considered, and the connection mode with the rivet is the connection mode with the highest cost performance. Thus, as an example, the band 2 connects the two ends of the strip together by riveting to form a circular ring. Through the optimized design of the mechanical property of the connection strength, the rivets are arranged in a diamond shape and have the best connection strength, and five rivets are respectively distributed in the rivet holes 25 distributed in the diamond shape. The arrangement scheme can ensure that each rivet is stressed uniformly and can utilize the positioning capacity of each rivet to the maximum.
It will be appreciated that the diamond-shaped arrangement of the five fasteners in the above embodiments is not a limitation on the location of the arrangement of the fasteners, and may be square or rectangular. The distribution of the fasteners can be reasonably set by a person skilled in the art according to actual conditions and needs as long as the connection strength of the barrel hoop 2 can be ensured.
Referring to fig. 1 again, the inner drum 1 of the drum washing machine includes a constant diameter section 11 and a variable diameter section 12 reducing the diameter toward the opening direction, and the drum hoop 2 is disposed at a position where the constant diameter section 11 transitions to the variable diameter section 12. Stress analysis shows that certain stress concentration exists at the position where the shape of the inner cylinder 1 changes, and the burst position frequently occurs at the position during high-speed rotation, so that the optimal effect of strengthening the strength of the inner cylinder 1 can be achieved by installing the hoop 2 at the position. The service life and the use experience of the drum washing machine are improved.
From the above description, it can be seen that the drum washing machine of the present invention includes an inner drum and a drum hoop disposed on an outer wall of the inner drum, where the drum hoop includes a plurality of hoop sheets and hooping, and the hooping is provided with a bend along a radial direction of the inner drum. The arrangement overcomes the phenomenon that the traditional barrel hoop is broken due to large tensile deformation when the inner barrel rotates at high speed, avoids the phenomenon that the tablets fly out of the machine body when the inner barrel bursts, and improves the strength of the barrel hoop and the safety of the inner barrel. Preferably, the bend is an inwardly recessed formation in the radial direction of the inner barrel. The deformation of the inner barrel can be reduced through the arrangement, the inner barrel is prevented from being burst due to overlarge rotating speed, the strength of the inner barrel is improved, and the service life of the inner barrel is prolonged. Preferably, bend and include a plurality of sections of bending along the axial of inner tube, the interval sets up between a plurality of sections of bending, and do not connect between a plurality of sections of bending. The hoop is easy to bend and deform due to the arrangement, so that the tensile deformation degree of the hoop is reduced, and the service life of the hoop is prolonged.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
