TECHNICAL FIELD
[0001] The utility model belongs to the technical field of basket washing machine, and relates to a basket washing machine, especially to a blowing and draining device of basket washing machine. BACKGROUND
[0002] The basket washing machine is a machine capable of cleaning a container with an open cavity, such as a frame or a turnover box. The basket washing machine generally comprises a shell, the shell has a transverse channel, a conveying line for conveying the basket directly passes through the inside of the channel, so that the basket can directly pass through the inside of the shell, the inside of the shell is provided with a spraying device and a blowing device, the spraying device can spray and clean the surface of the basket, and the blowing device is used to blow and dry the basket after cleaning. The conventional blowing device generally adopts the form of a wind knife matched with a high-pressure blower to blow, and the high-pressure blower generates a high-speed airflow which is finally blown out by the wind knife to blow off and dry the water drops on the basket.
[0003] The conventional wind knife layout can only be close to the outer surface of the basket or turnover box, and the wind knife is arranged above the basket to blow from top to bottom. However, the basket is generally placed on the conveying line with the cavity opening downward, and the blowing of the upper wind knife cannot blow the water on the inside of the basket, especially the water in the cavity of the basket, which is not conducive to drying. Even if a lower wind knife is arranged to blow from bottom to top, due to the large longitudinal depth of the cavity and the large spacing between the wind knife and the inner wall of the cavity, the high-pressure airflow cannot well take away the water drops in the cavity, so that a large amount of water remains in the inside of the basket or turnover box after washing. CONTENT
[0004] In view of the existing technical problems, the blowing and draining device of the basket washing machine is provided. The technical problem that the existing basket washing machine cannot well remove the water stains in the cavity of the basket is solved.
[0005] In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:
[0006] The blowing and draining device of the basket washing machine comprises a basket washing machine shell and a conveying chain arranged on the inside of the basket washing machine shell, characterized in that a lower wind knife is rotatably connected below the conveying chain and can be flipped up and down in the conveying direction of the conveying chain, a counterweight assembly is connected to the lower wind knife, the air outlet end of the lower wind knife can always be kept in a tendency of upward rotation under the driving of the counterweight assembly, and the position of the air outlet end is higher than the conveying plane of the conveying chain when the air outlet end is rotated upward to the limit position.
[0007] The inside of the basket washing machine of the application is provided with a conveying chain, and the inner cavity of the basket is placed on the conveying chain with the opening downward for transmission. A lower air knife is arranged below the conveying chain. The lower air knife is arranged in a rotatable form. When it rotates downward, it can be completely hidden below the conveying plane of the conveying chain (the position where the basket is placed). When it rotates upward, the air outlet end can be lifted to protrude above the conveying chain. The purpose of this design is that when the basket is conveyed, the outer edge of the basket will contact and push the protruding air outlet end to swing forward (i.e. downward) for avoidance. The outer edge of the basket is lifted upward by the weight assembly through the rear lower air knife and extends into the inner side of the inner cavity of the basket for air blowing. In this way, the inner cavity of the basket can be quickly dried by air blowing, and the drying effect is very good.
[0008] In the air blowing and draining device of the basket washing machine, the lower air knife is hinged to the basket washing machine shell. The hinge shaft on the lower air knife is perpendicular to the arrangement direction of the conveying chain. The height of the hinge position in the vertical direction is lower than the height of the conveying plane of the conveying chain. When the lower air knife is flipped downward, the whole lower air knife can be below the conveying plane for avoidance of the conveyed basket.
[0009] The lower air knife of the application is hingedly connected to the shell of the basket washing machine. The hinge position is entirely below the conveying chain, and the hinge shaft is perpendicular to the arrangement direction of the conveying chain. The lower air knife can be flipped up and down in the conveying direction of the conveying chain. When the outer edge of the basket collides with the lower air knife, the lower air knife can be rotated and submerged below the conveying chain in the conveying direction of the basket for avoidance. This design is only beneficial to the mechanical structure. The pushing force of the basket is used to passively change the position of the lower air knife. The lower air knife switches between the avoidance position and the air blowing position. This stable and efficient structure design realizes efficient and stable removal of water stains in the inner cavity of the basket.
[0010] In the air blowing and draining device of the basket washing machine, the air outlet end and the hinge position are respectively located at the opposite ends of the lower air knife, which is convenient for soft lifting.
[0011] The air outlet end and the hinge position on the lower air knife are oppositely arranged on one end. The hinge position is lower, and the air outlet end is higher. Under the driving of the weight assembly, the air outlet end is normally vertically arranged upward. The air outlet end can be rotated to avoid the small lateral force. When it is reset, the gravity of the whole lower air knife acts on the hinge position to resist the resetting force generated by part of the weight assembly, so that the lower air knife is reset more softly. In summary, this design can make the lower air knife avoid more quickly and reset more softly.
[0012] In the air blowing and draining device of the basket washing machine, the weight assembly includes a one-way damping joint. The one-way damping joint is arranged at the hinge position. The one-way damping joint can make the lower air knife lift upward gently.
[0013] The counterweight assembly of the present application comprises a one-way damping joint, which enables the avoidance of the downwind blade to be lifted and reset more gently, while meeting the effect of rapid dumping rotation when contacting the outer edge of the basket. The position switching of the downwind blade is very stable, and the removal of water stains in the cavity of the basket is more stable and efficient.
[0014] In the blow-drying device of the basket washing machine, the counterweight assembly comprises a counterweight block connected at the hinge position of the downwind blade to pull the downwind blade to rotate in the opposite direction.
[0015] This is another embodiment of the counterweight assembly of the present application, in which the counterweight assembly comprises a counterweight block directly connected to the side away from the air outlet end of the hinge position, which can play the same role of driving the downwind blade to rotate upward and reset.
[0016] In the blow-drying device of the basket washing machine, the end of the downwind blade near the hinge position is connected with a counterweight connecting pipe, which is used to connect with the high-pressure air inlet pipe.
[0017] The downwind blade of the present application is also connected with a counterweight connecting pipe with a counterweight at the other end of the hinge position, which is used to connect with the high-pressure air inlet pipe to provide high-pressure airflow for blowing. In addition, the counterweight connecting pipe also has a counterweight, which can provide a stronger resetting force at the hinge position, so that the rotation of the downwind blade is more rapid and gentle, and the position switching is faster, thereby better blowing and removing water stains on the inside of the basket.
[0018] In the blow-drying device of the basket washing machine, the conveying chain comprises two chain sections arranged in the horizontal direction and used to carry the basket, and the downwind blade is located at the interval between the two chain sections.
[0019] The conveying chain of the present application has two chains that move synchronously in the same direction, so that the lower edge of the basket on both sides can be stably conveyed by being abutted on the two conveying chains. The downwind blade of the present application is arranged between the two chain sections, so that when the downwind blade rotates upward, it can directly face the middle of the basket cavity for uniform blowing and water stain removal. Moreover, since the downwind blade switches positions by rotating, it can rotate and sweep the cavity of the basket during the rotation process, without dead angles for water stain removal.
[0020] In the blow-drying device of the basket washing machine, the air outlet end has a trapezoidal or fan-shaped structure, and the air outlet end has an air outlet, and the width of the air outlet is close to the interval between the two chain sections.
[0021] The air outlet end of the application is in the shape of a fan or a trapezoid, and is provided with an air outlet, the wide air outlet and the width of the basket cavity are close to each other, so that water stains can be removed better, and the overall weight of the air outlet end is increased due to the enlarged and widened design, so that the weight of the upper end of the air knife is increased, and the air knife can be pushed and turned away more easily and quickly when contacting the basket, so that the overall structure is more stable and efficient for blowing and removing water stains.
[0022] In the air blowing and draining device of the basket washing machine, the air outlet end of the air knife can be turned upward to a vertical state, and the vertical state is the limit position.
[0023] The limit position of the air knife turning upward is a vertical state, and the limit position of the air knife turning downward is a horizontal state avoiding the outer edge of the basket, and the position switching is about 90 degrees, so that the overall switching is faster, and when the air knife is in the vertical state, the air outlet of the air knife is closest to the bottom of the basket cavity, the air outlet angle is perpendicular to the bottom of the basket cavity, and water stains can be removed efficiently.
[0024] In the air blowing and draining device of the basket washing machine, the upper air blowing assembly is arranged on the top of the inner side of the basket washing machine.
[0025] The upper air blowing assembly is arranged on the top of the basket washing machine, and the air knife and the upper air blowing assembly can blow the inner surface and the outer surface of the basket at the same time, so that the water removal effect is very good.
[0026] The air knife is arranged in a rotatable form, can be completely hidden below the conveying chain when turning downward, and can be lifted above the conveying chain when turning upward, the outer edge of the basket contacts and pushes the air knife to tilt and turn away when the basket passes, and the air knife is lifted upward quickly under the driving of the counterweight assembly to blow air in the basket cavity after the outer edge of the basket passes, so that the basket cavity can be blown and dried quickly, and the drying effect is very good.

[0029] Embodiment one
[0030] As Figure 1The illustrated drying device for a crate washing machine includes a crate washing machine housing 1 and a conveyor chain 2 disposed inside the housing 1. The housing consists of a base and an outer shell. The conveyor chain 2 is mounted on the base, and the outer shell surrounds the outside of the conveyor chain 2 to form a transmission channel. Crates placed on the conveyor chain 2 can be transported along the direction of movement of the conveyor chain 2. The conveyor chain 2 includes two U-shaped chains. The upper edge of the chains is used to support the crates, and the chains form a loop by rotating. The upper edge of the two chains is called chain section 21. The two chain sections 21 are arranged horizontally at intervals to support the crates. A lower air blade 3 is located at the interval between the two chain sections 21. The lower edges of the crates abut against the two conveyor chains 2 for stable transport. A lower air blade 3 is rotatably connected below the conveyor chain 2, and the lower air blade 3 can rotate up and down in the conveying direction of the conveyor chain 2. A counterweight component 4 is connected to the lower air blade 3. Driven by the counterweight component 4, the air outlet 31 of the lower air blade 3 can always maintain an upward rotation trend, and when the air outlet 31 rotates upward to the limit position, the position of the air outlet 31 is higher than the conveying plane of the conveyor chain 2. The crate washing machine of this application has a conveyor chain 2 on its inner side. The crates are placed on the conveyor chain 2 with their inner opening facing downwards for transmission. A lower air knife 3 is set below the conveyor chain 2. The lower air knife 3 is designed to be rotatable. When rotated downwards, it can be completely hidden below the position where the crates are placed on the conveyor plane of the conveyor chain 2. When rotated upwards, the air outlet 31 can be raised and protrude above the conveyor chain 2. The purpose of this design is that when the crate is conveyed, the outer edge of the crate will contact and push the protruding air outlet 31 to swing forward or downward to avoid it. The outer edge of the crate is quickly raised upwards by the lower air knife 3 under the drive of the counterweight component 4 and extends into the inner cavity of the crate for blowing air. This can quickly dry the crate cavity, and the drying effect is very good.
[0031] Further, the lower air knife 3 is hinged on the washing basket machine shell 1, a crossbeam is arranged inside the washing basket machine shell 1 and is located below the conveying chain 2, the lower air knife 3 is hinged on the crossbeam and can be flipped up and down on one side. The hinge shaft on the lower air knife 3 is perpendicular to the arrangement direction of the conveying chain 2, the height of the hinge position 32 in the vertical direction is lower than the height of the conveying plane of the conveying chain 2, and when the lower air knife 3 is flipped down, the whole lower air knife 3 can be below the conveying plane for avoiding the transferred basket. The lower air knife 3 of the application is hingedly connected with the shell of the washing basket machine, the whole hinge position 32 is located below the conveying chain 2, and the hinge shaft is perpendicular to the arrangement direction of the conveying chain 2, which is equivalent to that the lower air knife 3 can be flipped up and down in the conveying direction of the conveying chain 2, when the outer edge of the basket collides with the lower air knife 3, the lower air knife 3 can be rotated and submerged below the conveying chain 2 along the conveying direction of the basket to avoid, which is only beneficial to the mechanical structure, and the position of the lower air knife 3 is passively changed by the thrust of the basket to switch between the avoiding position and the blowing position, which is stable and efficient to realize efficient and stable removal of water stains in the cavity of the basket. Preferably, the air outlet end 31 and the hinge position 32 are respectively located on the opposite ends of the lower air knife 3, which is convenient for soft lifting. The air outlet end 31 and the hinge position 32 on the lower air knife 3 of the application are oppositely arranged on one end, so that the hinge position 32 is below and the air outlet end 31 is above. Under the action of the counterweight assembly 4, the air outlet end 31 is normally vertically upward, so that the air outlet end 31 can be rotated to avoid the small lateral thrust, and when resetting, the gravity of the whole lower air knife 3 acts on the hinge position to resist part of the resetting force generated by the counterweight assembly 4, so that the lower air knife 3 is more soft to reset. In summary, the design can make the lower air knife 3 avoid more quickly and reset more softly.
[0032] Further, the counterweight assembly 4 of the application includes a one-way damping joint, which is arranged at the hinge position 32 and can make the lower air knife 3 soft to lift and reset. The one-way damping joint can make the avoiding lower air knife 3 more soft to lift and reset, and can meet the effect of quickly tilting and rotating when contacting the outer edge of the basket, which is very stable and convenient for position switching of the lower air knife 3, so that the removal of water stains in the cavity of the basket is more stable and efficient.
[0033] Further, the end of the lower air knife 3 close to the hinge position 32 is connected with a counterweight connecting pipe 33, which is used to connect with the high-pressure air inlet pipe 5. The lower air knife 3 of the present application is also connected with a counterweight connecting pipe 33 with a counterweight at the other end of the hinge position 32, which itself is used to connect with the high-pressure air inlet pipe 5 to provide high-pressure air flow for blowing. In addition, the counterweight connecting pipe 33 also has a counterweight, which can provide a stronger reset force at the hinge position 32, so that the rotation of the lower air knife 3 is more rapid on the basis of being gentle, and the position can be quickly switched to better blow and remove water stains in the basket.
[0034] Further, the air outlet end 31 is in a trapezoidal or fan-shaped structure, and has an air outlet on the air outlet end 31, the width of the air outlet is close to the interval between the two chain parts 21. The air outlet end 31 of the present application is in a fan-shaped or trapezoidal structure, and has an air outlet, the wide air outlet is close to the width of the basket cavity, which can better remove water stains, and the overall weight of the air outlet end 31 is increased by the design of being enlarged and widened, so that the increased weight of the upper end of the lower air knife 3 can more easily and quickly push and avoid the basket when in contact, so that the overall structure is more stable and efficient for blowing and removing water stains.
[0035] Further, the air outlet end 31 of the lower air knife 3 can be rotated upward to a vertical state, and the vertical state is the above-mentioned limit position. The limit position of the upward rotation of the lower air knife 3 of the present application is approximately a vertical state, and the downward rotation is basically a horizontal state avoiding the outer edge of the basket, which is approximately a 90-degree position switching, so that the overall switching is more rapid, and when in the vertical state, the air outlet of the lower air knife 3 is closest to the bottom of the basket cavity, and the outlet angle is basically perpendicular to the bottom of the cavity, which can efficiently remove water stains, and as the basket moves, the lower air knife 3 can sweep the bottom of the basket cavity, efficiently removing water stains.
[0036] Embodiment Two
[0037] This is another embodiment of the counterweight assembly 4 of the present application, in which other structures are basically the same as in Embodiment One, except that the counterweight assembly 4 includes a counterweight block connected at the hinge position 32 of the lower air knife 3 to pull the lower air knife 3 to rotate in the opposite direction. The counterweight block is directly connected to the side of the hinge position 32 away from the air outlet end 31, which can have the same effect of driving the lower air knife 3 to rotate upward and reset.
[0038] Embodiment Three
[0039] This is another embodiment of the application, in which other structures are basically the same as those of the first embodiment, and the difference is that the inner top of the basket washing machine is provided with an upper blowing assembly. The upper blowing assembly is preferably an upper air knife, which can be arranged symmetrically or staggered with the lower air knife 3, and can better blow and remove water stains. The top of the basket washing machine of the application is provided with an upper blowing assembly, and the upper blowing assembly cooperates with the lower air knife 3 to blow and remove water stains on the inner and outer surfaces of the basket at the same time, and the water removal effect is very good.
