Description
Technical Field
The invention relates to the field of industrial washing machines, in particular to a washing machine suitable for industrial production.
Background
In the production process of laundry, dyeing, dehydration, fixation and the like are required. The dyeing is a process of dyeing the fiber material with color, and after the dyeing of the clothes is completed, the floating color is required to be washed off by clean water, and in industrial production, a large-scale washing machine is commonly used for completing the washing process of a large number of clothes. With the maturity of production technology, modern industrial washing machine can be used to wash various cotton fabrics, wool fabrics, hemp, chemical fibre blending etc. clothing fabrics, has wide application in clothing factories, water washing factories, industrial and mining enterprises, schools, hotels, hospitals etc. laundry rooms, is the ideal equipment for reducing labor intensity, improving work efficiency, reducing energy consumption.
In industrial production, a common industrial washing machine is a horizontal washing machine, and the greatest difference is the capacity compared with a common household washing machine: the capacity of a common household washing machine is about 10 kg at most, and the maximum capacity of the existing industrial washing machine can reach 300 kg or more. Because of the large capacity, when the washing step is carried out, the clothes immersed with water and the high water quantity in the washing machine can generate larger pressure on the inner barrel, the outer barrel and the base of the washing machine, and in the rotating process of the washing machine, the impact and vibration on the inner barrel caused by the clothes immersed with water and the water quantity in the washing machine are larger, so that the inner barrel is often deformed or even damaged, and the service life of the washing machine is greatly shortened.
Disclosure of Invention
Accordingly, the present invention is directed to solving the above problems, and provides a washing machine suitable for industrial production, which reduces the damage probability of the washing machine and prolongs the service life of the washing machine.
The technical scheme of the invention is that the washing machine suitable for industrial production comprises an outer barrel, an inner barrel and a rotating shaft, wherein the outer barrel and the inner barrel are fixed on a machine base, and the rotating shaft is driven by a motor;
the inner barrel is coaxially and horizontally arranged in the outer barrel and is driven by the rotating shaft to rotate;
the surrounding wall of the inner barrel is provided with a plurality of small holes, and the surrounding wall of the inner barrel is provided with an inner door;
an outer door corresponding to the inner door is arranged on the surrounding wall of the outer barrel;
the inner barrel surrounding wall is provided with a plurality of inner convex edges.
In the prior art, a washing machine suitable for industrial production mainly comprises an outer barrel, an inner barrel and a rotating shaft, wherein the outer barrel and the inner barrel are fixed on a machine base, and the rotating shaft is driven by a motor; secondly, the industrial washing machine also comprises a water inlet, a water outlet, a transmission mechanism and a heat radiating device. Wherein, the rotating shaft, the transmission mechanism and the motor form a driving mechanism of the inner barrel, the inner barrel which is connected with the rotating shaft and used for washing clothes is sleeved in the outer barrel, and the inner barrel and the outer barrel are generally coaxially and horizontally placed; the water inlet is generally arranged at the middle upper part of the outer barrel, the water outlet is generally arranged at the bottom of the outer barrel and is connected with an external wastewater collection system; the heat sink is generally arranged at the upper part of the outer tub, and absorbs heat generated by the washing machine in a condensed water mode.
The outer barrel of the washing machine is a water tank and a water collector; in the process of washing clothes, the outer barrel is a water tank and is used for storing mixed liquid of tap water and detergent, the mixed liquid has a certain water level in the outer barrel and is used for soaking the clothes in the inner barrel, the inner barrel is driven by the rotating shaft to continuously rotate, and the clothes at the bottom of the inner barrel are lifted to a high position and then fall down for beating washing; in the dehydration process, the outer barrel is a water collector, the inner barrel rotates at a high speed under the drive of the rotating shaft, water in clothes is thrown out of the inner barrel from a plurality of small holes on the surrounding wall of the inner barrel under the action of centrifugal force, and the thrown water is collected by the outer barrel and is discharged out of the washing machine through a drainage system communicated with a water outlet at the bottom of the outer barrel.
In the process, in the process of washing clothes, the clothes at the bottom of the inner barrel fall from a high position to perform beating washing, and the impact force of the clothes on the inner barrel is huge because the clothes which are saturated with water are very heavy to 300 kg or higher, and furthermore, the clothes falling from the high position can bring impact force allowance to the outer barrel and the machine base; in the same way, in the process of dehydrating clothes, because the rotating shaft is required to rotate at a high speed, the clothes saturated with water can generate pulling force to the inside of the inner tub during the rotation process at the beginning of dehydration, so that the outer tub and the inner tub are easy to deform and damage after a period of use on the washing machine with a dehydration function whether the washing machine is used as a washing machine or a dehydrator.
Therefore, in the technical proposal, a plurality of inner convex edges are arranged on the inner barrel surrounding wall; the inner convex rib can adopt a surrounding edge structure with a triangular or quadrangular cross section, can also be made of a solid steel pipe or flat steel, and has a length slightly smaller than or equal to the inner length of the inner barrel; the inner convex rib can be made of the same material as the inner barrel, can serve as a reinforcing rib of the surrounding wall of the inner barrel, and greatly enhances the structural strength of the inner barrel after the inner convex rib is arranged on the premise of the inner barrel with the same size and the same wall thickness; when washing or dewatering is carried out, the internal barrel with increased structural strength is subjected to the impact of clothes saturated with water, the tolerance time is prolonged, namely the probability of compressive deformation is reduced, the impact on the external barrel and the machine seat is reduced, the damage probability of the washing machine can be reduced, and the service life of the washing machine is prolonged.
Further, as the stability of the triangle is better than that of a quadrangle, the cross section of the inner convex edge perpendicular to the axial direction of the rotating shaft is set to be a surrounding edge structure similar to a triangle, namely the cross section is a triangle and is an isosceles triangle, and the vertex of the triangle adopts arc transition, so that friction on clothes is reduced, and the clothes are prevented from being hooked or scratched; and secondly, the inner convex edges can be fixed on the inner wall of the inner barrel in a welding mode, and compared with solid steel pipes or flat steel, the triangular surrounding edge structure has more uniform welding seams during welding, so that stress concentration is reduced.
Furthermore, the triangular inner rib and the inner barrel are integrally formed, and an arc plate is welded at the concave parts of the triangular inner rib and the inner barrel, and the arc plate forms the bottom edge of the triangular inner rib, so that the structural strength of the inner barrel can be further enhanced.
Further, according to the different capacity sizes of the washing machine, 3 to 5 inner ribs can be arranged in the inner barrel and uniformly distributed in the inner barrel, the ratio of the maximum height of the inner ribs to the radius of the inner barrel is between 0.2 and 0.4, and the inner barrel is ensured to have enough strength, the inner space of the inner barrel is not occupied, and therefore the washing machine is ensured to have enough washing space.
Further, outer ribs are symmetrically arranged on two sides of the lower portion of the outer barrel, and an included angle alpha between the outer ribs and the lowest point of the outer barrel is 50-70 degrees.
In order to improve the structural strength of the outer tub, the simplest method is that the thickness of the outer tub material can be increased, but because the industrial washing machine is larger in size, the outer diameter of the outer tub can be 1.5 meters generally, the length can be 2.5 meters, if the thickness of the outer tub material is increased, the whole weight of the washing machine is increased, the transportation is inconvenient, and the manufacturing cost of the washing machine is increased due to the increase of the thickness of the outer tub material, therefore, in the technical scheme, the outer ribs are symmetrically arranged on two sides of the lower part of the outer tub, the outer ribs can be of a surrounding edge structure with triangular or quadrangular cross section, and can also be made of solid steel pipes or flat steel, and the length is slightly smaller than or equal to the length of the outer tub; the outer convex edges can be made of the same material as the outer barrel and can serve as reinforcing ribs of the outer barrel, and the structural strength of the outer barrel after the outer convex edges are arranged can be greatly enhanced on the premise of the outer barrel and the wall thickness of the outer barrel with the same size.
Generally, the water level in the washing machine is 1/5 to 1/3 of the water level in the outer tub, and the included angle alpha between the outer convex edge and the lowest point of the outer tub is 50 to 70 degrees, and further, the included angle alpha is 50 to 55 to 60 to 65 to 70 degrees by combining the outer diameter of the outer tub of the industrial washing machine with 1 to 1.5 meters; in other words, the outer ribs which are symmetrically arranged and fixed at two sides of the lower part of the outer tub are positioned at the left and right sides of the water level line in the washing machine, so that the aim of the arrangement is that the pressure under the water level line in the washing machine is the maximum when clothes washing or dewatering is carried out, and especially, the outer tub can also receive shearing force at two sides of the water level line, therefore, the outer ribs are arranged at the positions, and the structural strength of the outer tub can be increased.
Further, considering that the outer convex edge is positioned at the outer side of the outer barrel, in order to avoid damage to workers due to excessive sharp angles, the outer convex edge can be arranged to be trapezoid in cross section perpendicular to the axial direction of the rotating shaft, and further, the outer convex edge is of an isosceles trapezoid surrounding edge structure; secondly, the isosceles trapezoid-shaped outer protruding edges can be fixed on the outer side of the outer barrel in a welding mode, and compared with solid steel pipes or flat steel, the trapezoid-shaped surrounding edge structure is more uniform in welding seams during welding, so that stress concentration is reduced.
Further, when washing or dehydrating clothes, the outer tub below the water level of the washing machine is subjected to the greatest pressure, so that a thick plate is arranged between the outer ribs, i.e., in the area of the outer tub below the water level of the washing machine, thereby further enhancing the structural strength of the outer tub.
Further, the washing machine further includes a bridging device provided at an outside of the enclosing wall of the outer tub, for closing a gap between the inner tub and the outer tub when both the inner door and the outer door are opened.
Because the washing machine in this technical scheme still has the function of hydroextractor, consequently, there is certain clearance between outer bucket and the interior bucket of washing machine, generally between 60mm to 100mm, when the workman opens interior door and outer door after, in the time of delivering the clothing in the interior bucket, because the existence of clearance, can appear that the clothing drops in the clearance, if carelessly, when delivering and finish, wash or dewater when carrying out, the clothing that drops in the clearance can twine between outer bucket and interior bucket, leads to the trouble and shut down. In order to avoid the occurrence of the situation, in the technical scheme, a lap joint device is arranged for closing the gap between the inner barrel and the outer barrel; the clothes are prevented from falling into the gap, and the normal operation of the washing machine is maintained.
Further, the lap joint device comprises a toggle plate and a lap joint plate; the toggle plate is fixed on the outer side of the surrounding wall of the outer barrel; the lapping plate is rotationally connected with the toggle plate, and the effective length of the lapping plate is not smaller than the width of the gap between the inner barrel and the outer barrel.
Modern industrial washing machine commonly used, when seting up inner door and outer door, for convenient operation, at the beginning of the design, set up the inner door size slightly less than outer door, and set up the handle on outer door for the workman opens or closes outer bucket, and in order to guarantee its water tightness, be equipped with the sealing strip around the opening of inner bucket and outer bucket or the opening of inner door and outer door all around, and set up the strengthening rib around the opening of inner bucket and outer bucket, be convenient for increase opening part structural strength.
In the technical scheme, the lap joint device consists of a toggle plate and a lap joint plate, and when the inner door and the outer door are in a closed state, the lap joint plate is positioned at a naturally hanging position; when a worker opens the inner door and the outer door, the lapping plate is required to be folded first until the lapping plate completely covers the width of the gap between the inner barrel and the outer barrel, and then, the worker can put clothes to be washed into the inner barrel or remove dehydrated clothes, so that the clothes can be prevented from falling from the gap; wherein, the portion of the overlap plate that can cover the gap width is referred to as the effective length of the overlap plate.
Further, the lapping plate is L-shaped, the length of the long side of the L-shaped lapping plate is not smaller than the width of a gap between the inner barrel and the outer barrel, after the lapping plate is folded by a worker, the short side of the L-shaped lapping plate can be buckled on the inner side of an opening on the inner barrel, so that the lapping plate forms a relatively stable support structure between the inner barrel and the outer barrel, and the operation of the worker is facilitated.
Further, in order to enable the clothes to be immersed in water, the water level in the inner barrel needs to be 1/5 to 1/3 of the water level in the inner barrel, if the gap between the inner barrel and the outer barrel is larger, the water amount actually needed is larger, therefore, in order to reduce the water level in the outer barrel, the method for reducing the gap between the inner barrel and the outer barrel can be adopted, therefore, in the technical scheme, the inner door is arranged on the inner barrel in an inward manner, the outermost end of the handle arranged on the inner door is not more than the outer side of the surrounding wall of the inner barrel, the gap between the inner barrel and the outer barrel can be reduced by 40mm to 70mm, and accordingly, the water consumption for actually washing the clothes is reduced, the discharge of washing water is reduced, and pollution is reduced.
Compared with the prior art, the invention has the following beneficial effects:
1. the inner convex rib is arranged in the technical scheme, on the premise of the inner barrel and the wall thickness with the same size, the structural strength of the inner barrel is greatly enhanced, the probability of compressive deformation is reduced, the impact on the outer barrel and the machine seat is reduced, the damage probability of the washing machine can be reduced, and the service life of the washing machine is prolonged;

As shown in fig. 4, 4 inner ribs 31 are provided in the inner tub 3 and uniformly distributed inside the inner tub 3, wherein the ratio of the maximum height of the inner ribs 31 to the radius of the inner tub 3 is 0.27, and the inner tub 3 is ensured to have sufficient strength without occupying the inner space of the inner tub 3, thereby ensuring that the washing machine has sufficient washing space.
In the prior art, a washing machine suitable for industrial production is mainly composed of an outer tub 2 fixed on a machine base 1, an inner tub 3 and a rotating shaft 5 driven by a motor; next, the industrial washing machine further comprises a water inlet, a water outlet, a transmission mechanism and a heat dissipating device 6. Wherein, the rotating shaft 5, the transmission mechanism and the motor form a driving mechanism of the inner barrel 3, the inner barrel 3 which is connected with the rotating shaft 5 and is used for washing clothes is sleeved in the outer barrel 2, and the inner barrel 3 and the outer barrel are generally coaxially and horizontally arranged; the water inlet is generally arranged at the middle upper part of the outer barrel 2, the water outlet is generally arranged at the bottom of the outer barrel 2 and is connected with an external wastewater collection system; the heat sink 6 is generally provided at the upper portion of the tub 2 to absorb heat generated from the washing machine by means of condensed water.
The outer barrel 2 of the washing machine is a water tank and a water collector; in the process of washing clothes, the outer barrel 2 is a water tank and is used for storing a mixed solution of tap water and a detergent, the mixed solution has a certain water level in the outer barrel 2 and is used for soaking the clothes in the inner barrel 3, the inner barrel 3 is driven by the rotating shaft 5 to continuously rotate, and the clothes at the bottom of the inner barrel 3 are lifted to a high position and then fall down for beating washing; in the dehydration process, the outer barrel 2 is a water collector, the inner barrel 3 rotates at a high speed under the drive of the rotating shaft 5, water in clothes is thrown out of the inner barrel 3 through a plurality of small holes on the surrounding wall of the inner barrel 3 under the action of centrifugal force, and the thrown water is collected by the outer barrel 2 and is discharged out of the washing machine through a drainage system communicated with a water outlet at the bottom of the outer barrel 2.
In the process, in the process of washing clothes, the clothes at the bottom of the inner barrel 3 fall down from a high place to perform beating washing, and as the clothes fully saturated with water are very heavy to 300 kg or even higher, the impact force on the inner barrel 3 is huge, and furthermore, the clothes falling down from the high place can bring impact force allowance to the outer barrel 2 and the machine base 1; in the same manner, since the rotation shaft 5 is required to rotate at a high speed during the process of dehydrating laundry, a pulling force is generated in the inner tub 3 during the rotation of the laundry saturated with moisture at the beginning of the dehydration, and thus the outer tub 2 and the inner tub 3 are easily deformed and damaged after a certain period of use in the washing machine with a dehydrating function regardless of the use as the washing machine or the dehydrator.
Thus, in this embodiment, the inner tub 3 is provided with a plurality of inner ribs 31 on its peripheral wall; the inner rib 31 may have a triangular or quadrangular cross section and may be made of solid steel pipe or flat steel, and the length of the inner rib is slightly smaller than or equal to the inner length of the inner barrel 3; the inner rib 31 can be made of the same material as the inner barrel 3, can serve as a reinforcing rib of the surrounding wall of the inner barrel 3, and greatly enhances the structural strength of the inner barrel 3 after the inner rib 31 is arranged on the premise of the inner barrel 3 with the same size and the same wall thickness; when the washing or dehydrating step is carried out, the inner tub 3 with increased structural strength has increased tolerance time when receiving the impact of the clothes saturated with water, namely, the probability of compressive deformation is reduced, the impact on the outer tub 2 and the machine base 1 is reduced, the damage probability of the washing machine can be reduced, and the service life of the washing machine is prolonged.
As shown in fig. 6, outer ribs 21 are symmetrically arranged on two sides of the lower part of the outer barrel 2; generally, the water level in the washing machine is 1/5 to 1/3 of the inside of the outer tub 2, and the outer diameter of the outer tub 2 of the industrial washing machine is 1 m to 1.5 m, so that the angle α between the outer rib 21 and the lowest point of the outer tub 2 is 50 ° to 70 °, preferably, the angle α between the outer rib 21 and the lowest point of the outer tub 2 is 58 °, i.e., the outer rib 21 fixed at both sides of the lower portion of the outer tub 2 and symmetrically arranged is located at both sides of the water level in the washing machine, so that the pressure under the water level in the washing machine is the greatest, especially, the outer tub 2 receives a shearing force at both sides of the water level, and thus, the outer rib 21 is arranged therein, so that the structural strength of the outer tub 2 can be increased.
Further, considering that the outer rib 21 is located at the outer side of the outer tub 2, in order to avoid damage to workers due to excessive sharp corners, the outer rib 21 may be configured to have a trapezoid cross section perpendicular to the axial direction of the rotating shaft 5, and further, to have a surrounding edge structure of an isosceles trapezoid shape; secondly, the isosceles trapezoid-shaped outer protruding edges 21 can be fixed on the outer side of the outer barrel 2 in a welding mode, and compared with solid steel pipes or flat steel, the trapezoid-shaped surrounding edge structure is more uniform in welding seams during welding, so that stress concentration is reduced.
The modern industrial washing machine that uses is when seting up inner door 32 and outer door 24, for convenient operation, at the beginning of the design, sets up the size of inner door 32 slightly less than outer door 24, and sets up handle 23 on outer door 24 for the workman opens or closes outer bucket 2, and in order to guarantee its water proofness, is equipped with the sealing strip around the opening of inner bucket 3 and outer bucket 2 or around the opening of inner door 32 and outer door 24, and sets up the strengthening rib around the opening of inner bucket 3 and outer bucket 2, is convenient for increase opening part structural strength.
In this embodiment, as shown in fig. 7, the bridging means 4 is constituted by a toggle plate 41 and a bridging plate 42, said toggle plate 42 being fixed outside the peripheral wall of the outer tub 2; the lapping plate 42 is rotatably connected with the toggle plate 41, and the effective length of the lapping plate 42 is not smaller than the width of the gap between the inner barrel 3 and the outer barrel 2; the splice plate 42 is in a naturally depending position when the inner door 32 and the outer door 24 are closed; when the worker opens the inner door 32 and the outer door 24, the overlap plate 42 is folded first until the overlap plate 42 completely covers the width of the gap between the inner tub 3 and the outer tub 2, and then, the worker can put laundry to be washed into the inner tub 3 or remove dehydrated laundry, thereby preventing the laundry from falling from the gap; among them, a portion of the overlap plate 42 that can cover the gap width is referred to as an effective length of the overlap plate 42.
Preferably, the lapping plate 42 is L-shaped, and the length of the long side of the L-shape is not smaller than the width of the gap between the inner barrel 3 and the outer barrel 2, when the lapping plate 42 is folded by a worker, the short side of the L-shape can be buckled on the inner side of the opening on the inner barrel 3, so that the lapping plate 42 forms a relatively stable support structure between the inner barrel 3 and the outer barrel 2, and the operation of the worker is facilitated.
