A multi-barrel washing machine

Abstract

The multi-barrel washing machine provided by the present invention connects the first laundry treatment barrel structure and the third laundry treatment barrel structure together through a connecting frame. When the two are connected together, the overall weight is increased, and vibration can be effectively reduced. The support frame of the present invention is used to support the first, second, and third laundry treatment barrel structures. The first laundry treatment barrel structure is supported on the support frame through a damper, and the first and third laundry treatment barrel structures are connected to the support frame through elastic members. Since the first and third washing barrels are connected together through a connecting frame and then supported and fixed on the support frame through elastic members and damping shock absorbers, the amplitude generated during the operation of the multi-barrel washing machine can be reduced, and the overall operating conditions of the machine can be improved. The present invention can further reduce vibration by adding weights to any one or all of the first laundry treatment barrel structure and the third laundry treatment barrel structure. The first and third laundry treatment barrel structures of the present invention can be drum structures, and the second laundry treatment barrel structure is a pulsator structure. By setting different washing structures, the needs of different users can be met.

Description

Technical Field

[0001] The present invention relates to a washing machine, and more particularly to a multi-barrel washing machine. Background Art

[0002] Currently, most of the drum washing machines sold on the market have only one washing barrel. With the strengthening of people's health awareness, more and more users need to wash different types of clothes separately or wash a small amount of clothes in time. Therefore, users are no longer satisfied with the traditional laundry method of "washing in one barrel" and put forward a more healthy laundry requirement - "washing multiple times in one machine", that is, a washing machine can effectively distinguish and wash regular clothes, underwear, baby clothes, etc. If the existing washing machine is used for multiple laundry operations, it is difficult to meet the requirements in terms of washing time, and the washing efficiency is greatly reduced; if two or more washing machines are purchased and washed separately at the same time, it will not only cause great waste of energy and water resources, but also occupy a large space and is not suitable for household use. Therefore, the use of a multi-barrel washing machine can meet the above needs and effectively solve the multiple contradictions of energy, water and space.

[0003] In the related art, a combined washing machine with two or more washing barrels has a large number of pipelines inside the frame, a complex structure, troublesome installation, and occupies too much internal space due to its non-single washing barrel. On the premise that the space is originally limited, it is not conducive to the control of the overall volume of the washing machine. Currently, multi-barrel washing machines are gradually emerging on the market. Since one box body accommodates two or more washing barrels at the same time, the structural space appears very compact in the originally limited space.

[0004] In summary, the existing washing machines have the following problems:

[0005] 1. Most of the washing machines on the market are single-barrel washing machines. The washing machines can be divided into pulsator washing machines or drum washing machines in terms of types. Each of the two types of washing machines has its own advantages, but in most cases, users can only choose a drum washing machine or a pulsator washing machine during the process of purchasing a washing machine;

[0006] 2. With the improvement of living standards, users' washing needs have not only been satisfied with daily single-barrel washing. Multi-barrel partition washing has gradually emerged. The double-barrel combined washing machine runs stably, but only achieves double-barrel washing. With the improvement of living standards, it will inevitably gradually fail to meet the market demand. For washing machines with more than two barrels, in order to pursue the overall stability of the machine, the volume of the washing barrel will be reduced, affecting the practicability;

[0007] 3. The internal structural space of the washing machine with a multi-barrel structure layout is compact. Therefore, the connection method between the washing barrels will be somewhat difficult. The form, material selection, shape layout, etc. of the connecting parts will all affect the overall performance of the washing machine with a multi-barrel structure layout;

[0008] 4. The structure of a multi-barrel washing machine is complex, and the problem of the whole machine vibration is a difficult point in the structural design. Summary of the Invention

[0049] The following Figures 1 - 3 will describe in detail the content of the specific embodiments of the present invention:

[0050] Embodiment 1:

[0051] As Figure 1 shown, the present invention provides a multi-barrel washing machine, which includes at least three groups of clothing treatment barrel structures, namely the first, second, and third clothing treatment barrel structures 1, 2, and 3. The second clothing treatment barrel structure 2 is located above the first clothing treatment barrel structure 1, and the third clothing treatment barrel structure 3 is located above the second clothing treatment barrel structure 2. The first clothing treatment barrel structure 1 and the third clothing treatment barrel structure 3 are fixedly connected together through a connection frame 5. Among them, the first clothing treatment barrel structure 1 is called the lower barrel, the second clothing treatment barrel structure 2 can be called the middle barrel, and the third clothing treatment barrel structure 3 is called the upper barrel. By connecting the first clothing treatment barrel structure 1 and the third clothing treatment barrel structure 3 together through the connection frame 5, the third and third washing barrels are connected and fixed together, and the vibration can be significantly reduced.

[0052] Preferably, in the present invention, the first clothing treatment barrel structure 1 is the first washing barrel structure, the second clothing treatment barrel structure 2 is the second washing barrel structure, and the third clothing treatment barrel structure 3 is the third washing barrel structure. The first clothing treatment barrel structure 1 includes a first inner barrel and a first outer barrel, the second clothing treatment barrel structure 2 includes a second inner barrel and a second outer barrel, and the third clothing treatment barrel structure 3 includes a third inner barrel and a third outer barrel.

[0053] The three-barrel structure layout of the present invention: The first clothing treatment barrel structure 1 can be a large drum washing machine, also called the lower barrel, and the third clothing treatment barrel structure 3 can be a small drum washing machine, also called the upper barrel. The second clothing treatment barrel structure 2 can be a small pulsator washing machine, also called the middle barrel or the middle bucket. That is, the size of the lower barrel selected in the present invention is larger than that of the upper barrel, and the size of the lower barrel is larger than that of the middle barrel.

[0054] In an alternative embodiment of the present invention, the upper tub is a small drum washing machine (the first laundry treatment tub structure 1), the middle tub is a drawer - type mini - pulsator washing machine (the second laundry treatment tub structure 2), and the lower tub is a large drum washing machine (the third laundry treatment tub structure 3). A metal part (the connecting frame 5) that meets the requirements of stiffness and strength is used as the frame between the upper and lower drum washing machines, and the two are connected to each other through the metal connecting piece using screws. The selected material of the metal connecting piece meets the requirements of stiffness and strength, and there are various forms of metal frame structures that meet the connection between the two drum washing machines with different sizes and the above - mentioned up - and - down layout. The metal connecting piece is connected to the outer tub of the washing machine. Through - holes are provided on the metal connecting piece using stamping technology, and set screws are passed through the through - holes on the metal connecting piece and tightened on the outer tub of the washing machine to achieve the function of connection and fixation, so as to effectively support the two laundry drums placed one above the other and improve the overall machine support strength. Preferably, a space for accommodating the second laundry treatment tub structure 2 is formed in the middle part of the connecting frame 5, and the second laundry treatment tub structure 2 forms a drawer - type support structure. The upper tub is also called the upper drum washing machine, and the lower tub is also called the lower drum washing machine. The first laundry treatment tub structure 1 has a front panel 11 of the first laundry treatment tub structure, the third laundry treatment tub structure has a front panel 31 of the third laundry treatment tub structure, the support frame forms a bottom beam 41 of the support frame and a top beam 42 of the support frame.

[0055] As Figure 2 , as shown in Fig. 3, preferably, the connecting frame 5 forms four columns, namely the first, second, third, and fourth columns 54; the upper ends of the first column 51 and the second column 52 are fixedly connected with a first support member 55; the upper ends of the third and fourth columns 54 are fixedly connected with a third support member 57; the first support member 55 and the third support member 57 are fixedly connected with the third outer tub; the lower ends of the first and second columns 52 are fixedly connected with a second support member 56; the lower ends of the third and fourth columns 54 are fixedly connected with a fourth support member 58; the second support member 56 and the fourth support member 58 are fixedly connected with the first outer tub.

[0056] As Figure 2 , as shown in Fig. 3, preferably, at least part of the first support member 55 surrounds the third outer tub, and / or at least part of the second support member 56 surrounds the first outer tub, and / or at least part of the third support member 57 surrounds the third outer tub, and / or at least part of the fourth support member 58 surrounds the first outer tub. As Figure 3 shown, the second support member 56 surrounds the first outer tub, and the fourth support member 58 surrounds the first outer tub.

[0057] As Figure 2, as shown in Figure 3, preferably, the size of the first laundry treatment barrel structure 1 is larger than that of the third laundry treatment barrel structure 3. The connecting frame 5 includes a first frame, a second frame, and a third frame. The first frame is fixedly connected to the first laundry treatment barrel structure 1. The second frame forms a space for accommodating the second laundry treatment barrel structure 2. The third frame is fixedly connected to the third laundry treatment barrel structure 3. The size of the third frame structure is smaller than that of the first frame structure. Preferably, a connecting cross beam is further provided between the first and fourth columns 54, and a connecting cross beam is provided between the second and third columns 53.

[0058] As Figures 1 - 3 shown, preferably, the multi-barrel washing machine further includes a support frame 4 for supporting the first, second, and third laundry treatment barrel structures 3. Preferably, the lower part of the first laundry treatment barrel structure 1 is supported on the support frame 4 by a plurality of shock-absorbing dampers, and the upper part of the first laundry treatment barrel structure 1 is connected to the support frame 4 by a plurality of first elastic members 12; the upper part of the third laundry treatment barrel structure 3 is connected to the support frame 4 by a plurality of third elastic members. As Figure 3 shown, preferably, a counterweight is provided on the first outer barrel of the first laundry treatment barrel structure, and / or an additional counterweight is provided on the outer barrel of the third laundry treatment barrel structure.

[0059] After the upper barrel and the lower barrel are connected by a connecting member, an integral body is formed. Hanging spring fixing positions are provided on both sides above the upper barrel, and damping shock absorber fixing positions are provided on both sides below the lower barrel. The connecting integral body is elastically connected and fixed to the upper beam of the whole machine frame by the same number of hanging springs on the left and right, playing a shock-absorbing role; the connecting integral body is elastically connected and fixed to the lower beam of the whole machine frame by the same number of shock-absorbing dampers on the left and right, playing a shock-absorbing role. The upper barrel and the lower barrel are separately counterweighted, and the distribution of the counterweights does not interfere with each other, forming an independent counterweight system, making the operation of the whole machine more stable and safe.

[0060] In the present invention, the first and third laundry treatment barrel structures 3 are fixedly connected together through the connecting frame 4. Since the two are connected together, the weight is increased, and the vibration can be significantly reduced. At the same time, the first and third laundry treatment barrel structures 3 can be counterweights for each other. Therefore, the counterweight can be omitted. Since the first and third laundry treatment barrels are fixed together, their vibrations are consistent, and the vibrations of the two can be processed together. For example, when a counterweight is provided, they can be provided with a common counterweight. The connecting frame 4 forms an avoidance space (accommodation space) between the first and third laundry treatment barrel structures 3, which can be used as the accommodation space for the second laundry treatment barrel structure 2. Preferably, the second laundry treatment barrel structure 2 is arranged in the middle in the present invention. The second laundry treatment barrel structure 2 is formed into a drawer-type agitator structure, and its height from the ground is appropriate, which is convenient for operation. In the above structural form, compared with the three-barrel washing machine when the agitator structure is arranged at the top, since the agitator structure needs to be opened upward, its height is relatively high, which is inconvenient for operation by children and the like. In the present invention, the agitator structure is arranged in the middle and adopts a drawer-type structure, which is of a pull-out type and has an appropriate height, which is convenient for operation by children and the like. Preferably, both the upper barrel and the lower barrel are drum structures. Since the drum structure is opened by a side door, it will not cause inconvenience in operation due to its height when it is arranged at the top. The present invention cleverly uses the space formed by the connecting frame 4 to arrange a drawer-type agitator structure, making it convenient for operation and having a remarkable effect.

[0061] Embodiment 2:

[0062] As Figure 2 shown, another form of the connecting frame of the multi-barrel washing machine of the present invention is schematically shown. The upper barrel and the lower barrel are connected through the connecting frame 5 (metal connecting piece). The structural form of the metal connecting piece can be changed, the material selection can be changed, and the fixing method is set on the front panel and the rear panel of the outer barrel of the washing barrel, and is fixed by means of shock-proof set screws. As Figure 2 shown, the upper barrel and the lower barrel are connected through the connecting frame 5 (metal connecting piece). The structural form of the metal connecting piece can be changed, the material selection can be changed, and the fixing method is set on the front panel and the rear panel of the outer barrel of the washing barrel, and is fixed by means of shock-proof set screws. As Figure 2 shown, the upper part of the connecting frame 5 is fixedly connected to the lower part of the third laundry treatment barrel structure 3, and the lower part is fixedly connected to the upper part of the first laundry treatment barrel structure 1. Among them, the connecting frame 5 includes (upper horizontal beam), second and fourth support structures (lower horizontal beam) and columns (vertical beams), and the columns connect the upper and lower horizontal beams. The upper horizontal beam includes the first and third support structures) and 2 upper cross beams, which form a quadrilateral structure; the lower horizontal beam includes the second and fourth support structures and 2 lower cross beams, which form a quadrilateral structure. There are 4 columns.

[0063] Embodiment 3:

[0064] As Figure 3As shown in the figure, another form of the connection frame of the multi-barrel washing machine of the present invention is shown. The upper part of the connection frame 5 is fixedly connected to the lower part of the third laundry treatment barrel structure 3, and the lower part of the connection frame 5 is fixedly connected to the first laundry treatment barrel structure 1. At the lower part of the connection frame 5, each column (vertical beam) has at least two fixed points with the lower barrel in the vertical direction, and each column is fixed to the outer barrel of the lower barrel through a metal sheet structure (the second and fourth support structures).

[0065] As Figure 3 As shown in the figure, the upper drum washing barrel (upper barrel) and the lower drum washing barrel (lower barrel) are connected through a connecting member (connection frame 5) to form an integral body. Hanging spring fixing positions are provided on both sides above the upper barrel, and damping shock absorber fixing positions are provided on both sides below the lower barrel. The integral body is elastically connected and fixed to the upper beam of the whole machine frame through the same number of hanging springs on the left and right, playing a shock-absorbing role; the connection integral body is elastically connected and fixed to the lower beam of the whole machine frame through the same number of shock damping absorbers on the left and right, playing a shock-absorbing role. The upper barrel and the lower barrel are connected through a connecting member to form an integral body. Hanging spring fixing positions are provided on both sides above the upper barrel, and damping shock absorber fixing positions are provided on both sides below the lower barrel. The connection integral body is elastically connected and fixed to the upper beam of the whole machine frame through the same number of hanging springs on the left and right, playing a shock-absorbing role; the connection integral body is elastically connected and fixed to the lower beam of the whole machine frame through the same number of shock damping absorbers on the left and right, playing a shock-absorbing role. The upper drum washing machine and the lower drum washing machine are separately weighted, and the distribution of the counterweight blocks does not interfere with each other, forming an independent counterweight system, making the operation of the whole machine more stable and safe.

[0066] A metal connecting member is used to connect the upper drum washing machine (upper barrel) and the lower drum washing machine (lower barrel), and the position layout of the counterweight blocks is a split independent layout, that is, the counterweight blocks of the upper drum washing machine are separately laid out and fixed at the outer barrel of the upper drum washing machine; the counterweight blocks of the lower drum washing machine are separately laid out and fixed at the outer barrel of the counterweight of the lower drum washing machine.

[0067] The split independent counterweight block system can reduce the vibration during the operation of the whole machine, making the product operation safer, more reliable and quieter.

[0068] Embodiment 4:

[0069] As Figure 4As shown, another form of the support frame 4 of the multi-barrel washing machine of the present invention is illustrated. The support frame 4 includes a bottom beam 41 and a top beam 42. A second longitudinal beam 44 is provided on the top beam 42. The number of the second longitudinal beams 44 is illustrated as two, and an elastic member connecting portion, which may be a spring hanging hole 46, is provided thereon. The second elastic member can be connected to the second longitudinal beam 44 through the spring hanging hole 46. By providing the second longitudinal beam 44, since the distance between the hanging holes 46 is reduced compared with directly hanging on the top beam 42, that is, the possibility of the outer barrel of the washing barrel colliding with the column of the support frame 4 during vibration is reduced. Two first longitudinal beams 43 are connected to the bottom beam 41 of the present invention. The first longitudinal beam 43 forms a damper support portion, which may be a damper support seat 45. For the same principle as described above, by providing the first longitudinal beam 43 on the bottom beam 41, the installation position of the outer barrel of the washing barrel can be adjusted, and the possibility of the outer barrel of the washing barrel colliding with the column of the support frame 4 during vibration is reduced.

[0070] In summary, for the multi-barrel washing machine provided by the present invention, the first laundry treatment barrel structure 1 and the third laundry treatment barrel structure 3 are connected together through the connection frame 5. When the two are connected together, the overall weight is increased, and the vibration of the first laundry treatment barrel structure 1 and the third laundry treatment barrel structure 3 can be effectively reduced. Optionally, when the two are connected together, the size of the third laundry treatment barrel structure 3 is smaller than that of the first laundry treatment barrel structure 1, and the third laundry treatment barrel structure 3 is located above, which can be used as a counterweight for the first laundry treatment barrel structure 1 to reduce the vibration of the first laundry treatment barrel structure 1. The support frame 4 of the present invention is used to support the first, second, and third laundry treatment barrel structures 3. The first washing barrel is supported on the support frame 4 through a damper, and the first and third laundry treatment barrel structures 3 are connected to the support frame 4 through elastic members. Since the first and third washing barrels are connected together through the connection frame 5 and then supported and fixed on the support frame 4, the stability of the support can be improved, and the vibration can be further reduced. Optionally, by adding a counterweight to any one or all of the first laundry treatment barrel structure 1 and the third laundry treatment barrel structure 3, the vibration can be further reduced.

[0071] Beneficial effects:

[0072] In summary, the present invention realizes the mutual combination of various types of laundry barrels to meet the specific needs of users; the present invention achieves the following effects:

[0073] 1) This solution is a washing machine with a multi-barrel structure layout. The washing machine is superior to the double-barrel washing machines on the market, and the size of the laundry barrel can maintain a large-capacity washing with the blessing of the optimized frame structure, greatly enhancing the practicability of the multi-barrel washing machine.

[0074] 2) In this solution, the connection structure between multiple tub layouts is strong and reliable, capable of handling the vibrations generated when two washing tubs work simultaneously. The structural stiffness and strength meet the requirements of practical applications. At the same time, the structure is simple and the effect is remarkable, making it suitable for popularization and use.

[0075] 3) This solution reduces the vibrations generated by the washing machine with multiple tub layouts, realizes stable operation during the whole machine's work, and is safer.

[0076] 4) The layout of the multi-tub washing machine with a double drum washing machine + a drawer-type small wave wheel washing machine in this solution can meet the increasingly high washing requirements in the market, such as: partitioned washing, space saving, water and energy conservation, etc. The reasonable and user-friendly multi-tub layout will make users more handy during daily use, and the user experience will be more comfortable and convenient.

[0077] 5) The upper drum and the lower drum are connected through a specially designed metal connection frame 5, which can improve the utilization rate of the internal space of the whole machine and make the structural design more compact.

[0078] 6) The position layout of the hanging springs and damping shock absorbers in the present invention reduces the vibration impact on the whole machine when multiple washing tubs work simultaneously.
