Description

Technical Field

[0001] The invention relates to a washing machine frame structure, in particular to a multi-barrel washing machine frame structure. Background Art

[0002] At present, most drum washing machines sold on the market have only one washing drum. With the strengthening of people's awareness of hygiene, more and more users need to wash different types of clothes in different categories or wash a small amount of clothes in time. With the increasing improvement of modern living standards and the opening of the national two-child policy, more and more household consumers are no longer satisfied with the traditional laundry method of "one bucket washing" and have put forward a healthier laundry requirement - "one machine for multiple washings", that is, one washing machine can effectively distinguish between regular clothes, underwear and baby clothes. If the existing washing machine is used for multiple washing, it is difficult to meet the requirements in terms of washing time; if two or more washing machines are purchased for separate washing at the same time, it will not only bring great waste of energy and water resources, but also occupy a large space and is not suitable for family use. Therefore, the use of multi-barrel washing machines can meet the above needs and can effectively solve the multiple contradictions between energy, water and space.

[0003] In the related art, there are combined washing machines with two or more washing tubs. Since there is not one washing tub, there are many pipes inside the frame, the structure is complex, and the installation is troublesome. Moreover, it takes up too much internal space, which is not conducive to the control of the volume of the whole machine under the premise that the space is originally limited. At present, multi-barrel washing machines are gradually appearing on the market. Since one box can accommodate two or more washing tubs at the same time, the structure is very compact in the originally limited space, which makes the pipe design a major problem. As an indispensable part of it, the reasonable layout design of multiple drainage pipes is particularly important. Summary of the invention

[0057] Preferably, the pipeline formed by the third column 3 is also used as an exhaust flow path, the exhaust ports of multiple washing tubs are connected to the pipeline formed by the third column 3, and the upper part of the third column 3 is provided with an exhaust outlet connected to the outside air.

[0058] like Figure 1-8 As shown, the present invention also provides a multi-barrel washing machine, which adopts any frame structure described in the present invention. Preferably, the multi-barrel washing machine is a three-barrel washing machine, wherein the first washing tub 100 is a drum structure, the second washing tub 200 is a pulsator structure, and the third washing tub 300 is a drum structure.

[0059] like Figure 1-4 As shown, the multi-barrel washing machine frame structure of the present invention adopts a hollow support rod, and optionally, adopts an internally enclosed and high-strength single-pass and double-pass rectangular pipe (the first column 1 adopts a double-pass rectangular pipe), and after cutting / internal enclosing according to relevant dimensions, the multi-barrel washing machine frame structure is formed by welding; and the multi-barrel washing machine frame structure is mainly composed of frame columns, a top frame 9, a cross beam, a base 5, a reinforcing plate, an overflow connection port, a water inlet connection port, a water outlet connection port, a drainage connection port, a total drainage outlet 40, an exhaust port, a U-shaped tension spring base, and a damping shock absorber base, and the damping shock absorber base includes a first shock absorber seat 51 and a second shock absorber seat 71.

[0060] The frame structure of the multi-barrel washing machine of the present invention can realize the function of fixing the washing barrel, and can also serve as a part of the water inlet pipe, drainage pipe, overflow pipe and exhaust pipe, thereby reducing the layout of the internal water pipes of the multi-barrel washing machine, saving internal space, and achieving the effect of one object with multiple uses. The three washing barrels of the multi-barrel washing machine are independently fixed by the multi-barrel washing machine frame of the present invention, which can effectively control or weaken the vibration effect of the washing barrel; the multi-barrel washing machine frame of the present invention adopts single-pass and double-pass rectangular pipes with controllable internal closed position and high strength, which effectively enhances the strength and stability of the frame. The versatility of the multi-barrel washing machine frame of the present invention can improve the compactness of the interior of the multi-barrel washing machine, and has a simple structure and convenient assembly; and the present invention has a simple structure and significant effect, and is suitable for promotion and use.

[0061] like Figure 5-8 As shown, the present invention fixes three washing tubs independently on the frame of the multi-tub washing machine through tension springs and damping shock absorbers; the tension springs include a first tension spring 102 and a second tension spring 302; the damping shock absorbers include a first damping shock absorber 101 and a second damping shock absorber 301. First, the bottom of the first washing tub 100 is fixed on the frame base 5 through the damping shock absorber, and the top of the first washing tub 100 is fixed on the inner side of the lower crossbeam 6 through the first tension spring; the second washing tub 200 can be a drawer-type structure, and the left and right sides can be fixed on the frame rails by screws. When it is a non-drawer-type structure, the rails can be replaced by reinforcing plates. The bottom of the third washing tub 300 is fixed on the upper crossbeam 7 through the second damping shock absorber 301, and the top is fixed on the inner side of the frame top frame 9 through the second tension spring; wherein the tension spring base / damping shock absorber base is fixed to the required frame position by welding; wherein the damping shock absorber and the shock absorber base can be fixed by shock absorber pins or bolts.

[0062] like Figure 6 As shown in Figure 7, the frame structure of the multi-barrel washing machine of the present invention preferably has the function of the water inlet pipelines of the three washing barrels: by controlling the open and closed states of the cross-section of the pipe material of the multi-barrel washing machine frame, two independent water inlet pipelines are formed inside the first column 1 of the multi-barrel washing machine frame, the first one leading to the first washing barrel 100, and the second one leading to the second washing barrel 200; the water inlet pipeline of the third washing barrel 300 is directly connected to the water inlet solenoid valve through the water inlet connecting pipe to enter the third washing barrel 300 (forming an extremely short water inlet pipeline, occupying very little space). The two water inlet pipelines formed by the multi-barrel washing machine frame are independent of each other and do not interfere with each other, ensuring that the water inlet function of the three washing barrels is guaranteed.

[0063] The water inlet pipes corresponding to the three washing buckets are specifically as follows: the water inlet pipe of the first washing bucket 100: water inlet solenoid valve interface—first water inlet connecting pipe 103—first water inlet connecting port 13—first washing bucket 100 frame water inlet pipe—first water outlet connecting port 11—first water inlet hose 105—first washing bucket water inlet 106; the water inlet pipe of the second washing bucket 200: water inlet solenoid valve interface—second water inlet connecting pipe 203—second water inlet connecting port 14—second washing bucket 200 frame water inlet pipe—second water outlet connecting port 12—second water inlet hose 205—second washing bucket water inlet 206; the water inlet pipe of the third washing bucket 300: water inlet solenoid valve—third water inlet connecting pipe 303—third washing bucket water inlet 306.

[0064] like Figure 5 As shown, the frame structure of the multi-barrel washing machine of the present invention has the function of the drainage pipeline of three washing barrels: by controlling the open and closed state of the cross section of the pipe material of the multi-barrel washing machine frame, the inside of the fourth column 4 of the multi-barrel washing machine frame acts as a drainage pipeline shared by the three washing barrels at the top, middle and bottom, and a drainage connection port is provided at the corresponding position of the fourth column 4 of the frame. The three washing barrels have three corresponding drainage pumps respectively, forming three independent drainage pipelines that are unified. The drainage pipeline is composed of the first, second, and third drainage connecting pipes 304, the drainage pipeline formed by the fourth column 4 of the frame, etc. The three drainage pipes are finally all collected to the drainage main pipe. It is ensured that even if each washing barrel has a common part of the pipeline, it can form three independent drainage pipelines, which can meet the functions of simultaneous drainage or separate drainage.

[0065] The drainage pipes corresponding to the three washing buckets are as follows: drainage pipe of the first washing bucket 100: drainage outlet 40 of the first washing bucket 100 - first drainage connecting pipe 104 - drainage pump of the first washing bucket 100 - first drainage connecting port 41 - frame drainage pipe of the first washing bucket 100 - drainage outlet 40 - main drainage pipe; drainage pipe of the second washing bucket 200: drainage outlet 40 of the second washing bucket 200 - second drainage connecting pipe 204 - drainage pump of the second washing bucket 200 - second drainage connecting port 42 - frame drainage pipe of the second washing bucket 200 - drainage outlet 40 - main drainage pipe; drainage pipe of the third washing bucket 300: drainage outlet 40 of the third washing bucket 300 - third drainage connecting pipe 304 - drainage pump of the third washing bucket 300 - third drainage connecting port 43 - frame drainage pipe of the third washing bucket 300 - drainage outlet 40 - main drainage pipe.

[0066] like Figure 8As shown, the frame structure of the multi-barrel washing machine of the present invention has the function of an overflow pipe for three washing barrels; by controlling the open and closed states of the cross-section of the pipe of the multi-barrel washing machine frame, the interior of the third column 3 of the multi-barrel washing machine frame serves as an overflow pipe shared by the upper, middle and lower three washing barrels, and overflow connection ports are provided at corresponding positions of the third column 3 of the frame, namely, the overflow connection port of the first washing barrel 100, the overflow connection port of the second washing barrel 200, and the overflow connection port of the third washing barrel 300, which can satisfy the overflow function of the three washing barrels at the same time or individually, ensuring that when each washing barrel of the washing machine is in an abnormal water inlet state, the interior of each washing barrel is full of water to achieve overflow safety.

[0067] The overflow pipes corresponding to the three washing buckets are specifically as follows: overflow pipe of the first washing bucket 100: overflow port of the first washing bucket 100 - first overflow connecting pipe - first overflow connecting port 31 - overflow pipe of the first washing bucket 100 - overflow outlet - main drainage pipe; overflow pipe of the second washing bucket 200: overflow port of the second washing bucket 200 - second overflow connecting pipe - second overflow connecting port 32 - overflow pipe of the second washing bucket 200 - overflow outlet - main drainage pipe; overflow pipe of the third washing bucket 300: overflow port of the third washing bucket 300 - third overflow connecting pipe - third overflow connecting port 33 - overflow pipe of the third washing bucket 300 - overflow outlet - main drainage pipe.

[0068] like Figure 8 As shown, the frame structure of the multi-tub washing machine of the present invention has the function of the exhaust pipe of the three washing tubs, so that the internal air pressure of the three washing tubs is connected to the atmosphere. By using the overflow pipe described above, an exhaust hole is opened on the top side wall of the third column 3 of the frame, which can ensure that the inner cavities of the three washing tubs are connected to the atmosphere through the overflow pipe, ensure the balance of internal and external air pressure, and ensure the safety and stability of the three washing tubs of the washing machine when water is added at the same time or separately.

[0069] The exhaust ducts corresponding to the three washing tubs are specifically as follows: exhaust duct of the first washing tub 100: overflow outlet of the first washing tub 100 - first overflow connecting pipe - first overflow connecting port 31 - exhaust duct of the first washing tub 100 - exhaust hole - atmosphere outside the box; exhaust duct of the second washing tub 200: overflow outlet of the second washing tub 200 - second overflow connecting pipe - second overflow connecting port 32 - exhaust duct of the second washing tub 200 - exhaust hole - atmosphere outside the box; exhaust duct of the third washing tub 300: overflow outlet of the third washing tub 300 - third overflow connecting pipe - third overflow connecting port 33 - exhaust duct of the third washing tub 300 - exhaust hole - atmosphere outside the box.

[0070] Preferably, the exhaust pipe and overflow pipe of the multi-barrel washing machine frame are actually shared, and both share the third column 3 of the vertical pipe frame, but the exhaust pipe goes upward (because the air is discharged upward) and the overflow pipe goes downward (because water flows downward).

[0071] like Figure 3 As shown in Figure 4, the cross-section of the pipe used in the frame is closed, and its cross-sectional shape can be rectangular, square, or circular, and can be used according to the function of the frame.

[0072] The frame structure of the present invention is only a schematic diagram. In order to improve the strength of the frame, the structure formed by increasing the number of horizontal or vertical reinforcement plates is also within the protection scope of the present invention. The multi-barrel washing machine frame is mainly composed of horizontal pipes, vertical pipes, frame reinforcement plates, water inlet connections, first washing tub 100 / second washing tub water inlet 206, first, second, and third drainage connections, first, second, and third overflow connections, total drainage outlet 40, exhaust port, tension spring base, and damping shock absorber base.

[0073] Combination Figure 1-8 As shown, the manufacturing and installation process of the present invention can be carried out as follows:

[0074] (1) Material preparation and cutting: Use single-pass and double-pass rectangular pipes (only the first frame column 1 uses double-pass rectangular pipes), and cut them into sections according to the required specifications and sizes based on the frame structure shown in the figure, and then seal or drill holes to open the pipeline in advance according to the requirements of the pipeline design. Cut and process the water inlet connection port, the first and second water inlets, the first, second and third drainage connection ports, the first, second and third overflow connection ports, the total drainage outlet 40, and the exhaust port according to the required specifications for subsequent use. Use a steel plate of a certain thickness to stamp out the damping shock absorber base, and open a hole in the middle of the plane. Each damping shock absorber needs 2 to be fixed at the bottom end for the fixing of the shock absorber pin; the number of damping shock absorbers required for each washing tub varies from 2 to 4 (the number is adjusted according to the actual vibration effect of the multi-barrel washing machine to meet the needs). The present invention can be implemented according to 4 damping shock absorbers per tub, so a total of 16 are required for the first washing tub 100 and the second washing tub 200.

[0075] like Fig. 9As shown, the tension spring base is made of a steel plate of a certain thickness, cut and bent at 4 appropriate angles, and bent into a concave symmetrical structure of the required size, and then screw holes are punched at appropriate positions on the extended planes on both sides for fixing, and finally a U-shaped groove structure is cut out on the plane in the middle position of the structure for the lower barrel tension spring suspension, so that the upper / lower barrel tension spring base is successfully made (the bending size / U-shaped groove structure position is determined according to the upper / lower barrel structure requirements), and the sizes of the upper and lower barrel tension spring bases may be different, specifically determined according to the spatial position and its bearing strength. The number of tension springs required for each washing tub ranges from 2 to 4 (the number is adjusted according to the actual vibration effect of the multi-barrel washing machine to meet the needs), and this embodiment is implemented according to 1002 for the first washing tub / 3004 for the third washing tub, for a total of 6.

[0076] Welding: As shown in the structure diagram, the prepared horizontal pipes, vertical pipes, frame reinforcement plates, water inlet connection port, first washing bucket 100 / second washing bucket water inlet 206, drainage connection port 1 / 2 / 3, first overflow connection port 31 / 2 / 3, total drainage outlet 40, exhaust port, tension spring base, damping shock absorber base, etc. are welded together according to the structural diagram. The welding quality requires fullness and no water leakage.

[0077] Installation of three washing tubs: The top of the first washing tub 100 (lower tub) is suspended on the lower tub tension spring base (fixed on the inner side of the frame crossbeam) through four tension springs, one end of which is suspended on the tension spring hook of the outer tub of the third washing tub 300; the bottom is fixed on the frame base 5 through four damping shock absorbers, one end of the damping shock absorber is connected to the outer tub of the third washing tub 300, and the other end is connected to the shock absorber fixing seat pre-installed on the frame base 5. The upper and lower ends of the damping shock absorber can be fixed by shock absorber pins or bolts. The second washing tub 200 (middle tub) is connected to the frame reinforcement plate through a sliding connector and fixed with screws (since the position of the second washing tub 200 is not very relevant to the present invention, it will not be elaborated on in detail); the top of the third washing tub 300 (upper tub) is suspended on the upper tub tension spring base (fixed on the inner side of the frame top basket) through four tension springs, and the other end is suspended on the tension spring hook of the outer tub of the third washing tub 300; the bottom is fixed on the frame crossbeam through four damping shock absorbers, one end of the damping shock absorber is connected to the outer tub of the third washing tub 300, and the other end is connected to the shock absorber fixing seat pre-installed on the frame crossbeam. The upper and lower ends of the damping shock absorber can be fixed by shock absorber pins or bolts.

[0078] Installation and realization of the water inlet pipeline function: fix the water inlet three-way solenoid valve on the box body, and then use the water inlet connecting pipe to connect with the corresponding frame water inlet connection port to form three independent water inlet pipelines. Install and realize the drainage pipeline function and the overflow pipeline function.

[0079] The present invention is optional, the exhaust duct and overflow duct of the multi-barrel washing machine frame are actually shared, and both share the third column 3 of the vertical duct frame, but the exhaust duct goes upward (because the air is discharged upward) and the overflow duct goes downward (because the water flows downward).

[0080] The frame structure of the present invention is also referred to as a frame.

[0081] Beneficial effects:

[0082] To sum up, the multi-barrel washing machine frame of the present invention, as a part of the water pipeline, can reduce the layout and installation of the water pipeline inside the multi-barrel washing machine, so that while ensuring the function of the multi-barrel washing machine remains unchanged, the required internal space is greatly reduced, the compactness of the interior of the washing machine is improved, the structure is simple, the assembly is convenient, and it is beneficial to control the volume of the whole machine, reduce the manufacturing cost of the washing machine, the effect is remarkable, and it is suitable for promotion and use.

[0083] The multi-barrel washing machine frame of the present invention can realize the function of fixing and installing each washing barrel, and the multiple barrels are relatively independently fixed, and the overall vibration intensity can be reduced by respectively weakening the vibration intensity of each barrel. The multi-barrel washing machine frame of the present invention can adopt high-strength internal through-type pipes, which can realize the internal closure and opening of the required position inside the pipe, so that the frame also has the function of serving as the water inlet pipe, drainage pipe, overflow pipe and exhaust pipe of multiple washing barrels, and can simultaneously meet the multiple functions of multiple washing barrels working simultaneously or independently, so as to achieve the purpose of multiple uses of one object.

[0084] The multi-barrel washing machine frame structure of the present invention, the water inlet pipe, the drainage pipe, the overflow pipe and the exhaust pipe in the frame structure are not limited to the above-mentioned scheme, and can be combined and transformed in different ways according to the structural characteristics of the washing barrel, but the closed / open position of the pipe should be reasonably selected according to the functional requirements of the frame of the multi-barrel washing machine; in the multi-barrel washing machine frame structure provided by the present invention, while satisfying the above functions, it is not limited to the above structural characteristics, and according to the load-bearing capacity of the frame, the number of horizontal or vertical reinforcement plates assembled can be reasonably increased to enhance the strength of the multi-barrel washing machine frame.
