Shoe washing machine inner drum, shoe washing method and control flow thereof

Abstract

This invention discloses an inner drum of a shoe washing machine, a shoe washing method, and its control process. It relates to footwear cleaning equipment and aims to solve the problem that simply rotating the drum in reverse to collect the washing particles into the spiral tube during rotation results in insufficient collection efficiency. The key technical points are: a spiral-structured collection channel is formed within the collection chamber; a receiving port communicating with the collection channel is provided on the dividing plate; several material-blocking protrusions are distributed in a ring array on the inner circumferential wall of the drum; and inlet and outlet holes are provided on the circumferential wall of the drum, located only at the receiving port. This invention achieves efficient displacement of the washing particles into the collection channel during low-speed rotation, as the washing liquid is discharged and the washing particles are displaced towards the inlet and outlet holes by the water flow. Under mutual compression, they are collected into the collection channel. Because the inlet and outlet holes are only located on the circumferential wall of the drum near the receiving port, the washing particles can be efficiently displaced into the collection channel. Furthermore, the washing particles located in the collection channel are displaced towards the axial position during washing, improving the collection rate of the washing particles.

Description

Technical Field

[0001] This invention relates to footwear cleaning equipment, and more specifically, to a shoe washing machine inner cylinder, a shoe washing method, and a control process thereof. Background Technology

[0002] Due to the special nature of shoe construction, traditional shoe cleaning methods typically involve manual brush cleaning. To reduce the workload of shoe cleaning, especially in the cleaning and maintenance service industry, the traditional cleaning methods are still used, resulting in high labor costs and cumbersome cleaning steps.

[0003] Chinese Patent Publication No. CN113106702A discloses a shoe washing method and device. The key technical points are: using washing aid particles to clean shoes through repeated rolling and tumbling, then automatically separating the washing aid particles from the shoes and collecting them. The solution mainly relies on the structure of its roller drum, specifically: a transfer device consisting of a spiral tube and partition plates is fixed inside the roller drum, and the washing chamber and the collection chamber are connected through the openings at both ends of the spiral tube.

[0004] The above solution achieves the goal of efficient cleaning of the shoe cavity and upper. However, when storing the cleaning aid particles, they need to be inserted into the storage compartment through a spiral tube. The position of the spiral tube is fixed, and the cleaning aid particles are only stored in the spiral tube by rotating the drum in the opposite direction during storage, resulting in low storage efficiency.

[0005] Therefore, a new solution is needed to address this problem. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an inner cylinder of a shoe washing machine, a shoe washing method and its control process.

[0007] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a shoe washing machine inner cylinder, including a drum, wherein the drum is divided into a washing chamber and a storage chamber, the washing chamber and the storage chamber are separated by a partition plate, the storage chamber has a spiral storage channel, the partition plate has a receiving port communicating with the storage channel, the inner peripheral wall of the drum has a plurality of material blocking protrusions arranged in a ring array, and the peripheral wall of the drum has liquid inlet and outlet holes located only at the receiving port.

[0008] The present invention is further configured such that: a triangular-shaped receiving guide is raised on the side of the separator plate facing away from the receiving compartment, and a plurality of feeding grooves are provided on one side surface of the receiving guide along the rotation direction of the roller receiving.

[0009] The present invention is further configured such that the cross-section of the receiving guide is an obtuse triangle and the angle of the receiving guide is 120-150°.

[0010] The invention is further configured such that: the inner wall of the roller is provided with a material-blocking brush located on one side of the liquid inlet / outlet hole and the receiving guide, the material-blocking brush being used to provide a damping force to prevent the washing aid particles from leaving the liquid inlet / outlet hole.

[0011] The present invention is further configured such that: the cross-section of the material-blocking protrusion is an acute triangle, the receiving guide and the material-blocking brush are both disposed between two adjacent material-blocking protrusions, and the distance from the tip of the material-blocking protrusion to the axis of the roller is greater than the distance between the axis of the receiving guide and the material-blocking brush.

[0012] The invention is further configured such that: the roller has a feeding port communicating with the washing chamber; the side of the roller facing away from the feeding port is recessed towards the washing chamber to form a frustum-shaped recess; and the receiving channel has a pressure relief hole penetrating the roller near the central axis of the roller.

[0013] A shoe washing method, characterized in that it is applied to shoe washing equipment equipped with a shoe washing machine inner cylinder, and the cleaning method is as follows:

[0014] For the initial soaking, put the cleaning aid granules and the shoes to be cleaned into the drum, submerge the shoes in the cleaning aid granules, and then pour it into the shoe washing equipment, submerging the shoes and cleaning aid granules in the drum;

[0015] For detergent cleaning, inject detergent into the drum, set the washing mode and start the washing process, and drain the wastewater after the washing is finished.

[0016] After dehydration and cleaning, and drainage, the high-speed rotating drum is inserted and removed after initial dehydration, and then re-injected into the cleaning system for a second rinse.

[0017] After draining and dehydrating, rotate the drum in the opposite direction until the washing aid particles are collected into the collection channel.

[0018] Drying: Remove the shoes one by one from the drum for drying.

[0019] The present invention is further configured such that the specific method of draining and dehydrating is as follows: after completing the second rinsing, the shoe washing equipment starts the dehydration program, opens the drain valve of the shoe washing equipment, and the washed water flows out to the drain pipe. In the drum, a pressure difference is formed with the water flow. At the same time, when the drum rotates slowly in the opposite direction, the washing particles intermittently fall between two adjacent material blocking protrusions and move towards the inlet and outlet holes with the water flow. Under the rotation of the drum, the washing aid particles are squeezed against the collection guide and enter the spiral structure collection channel for collection.

[0020] The control process of the shoe washing equipment is characterized by the following:

[0021] Set the washing mode, and according to the type of shoes to be washed, set the washing time, drum speed, number of washes, and soaking time;

[0022] Set the drainage mode, and according to the type of shoes being washed, set the direction of the drum's rotation and the speed of the reverse drum.

[0023] The present invention is further configured such that: the washing time and the rotation speed of the drum are set according to the type of shoes being washed, respectively:

[0024] For washing skateboard shoes, set the washing time to 15-20 minutes and the drum speed to 1200 rpm.

[0025] For washing athletic shoes, set the washing time to 20-25 minutes and the drum speed to 1200-1400 rpm.

[0026] In summary, the present invention has the following beneficial effects:

[0027] With a single drainage point, the number of times the shoes tumble inside the drum can be increased. This allows the washing aid particles inside the shoe cavity to come out of the cavity and be collected in the collection channel. Since the collection channel has a spiral structure, it can maintain a constant rotation during dehydration, thus preventing the washing aid particles from falling out of the collection chamber.

[0028] At low speeds, the washing liquid is discharged, and the auxiliary washing particles are displaced by the water flow towards the inlet and outlet. Under the mutual squeezing force, they are collected into the collection channel. Since the inlet and outlet holes are only opened on the drum peripheral wall near the receiving port, the auxiliary washing particles can be efficiently displaced into the collection channel. The auxiliary washing particles located in the collection channel are displaced towards the axis position with the water washing, improving the collection rate of auxiliary washing particles.

[0034] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] Example 1:

[0036] The inner drum of the shoe washing machine, such as Figures 1 to 3 As shown, the device includes a drum 1, which is divided into a washing chamber and a storage chamber. The washing chamber and the storage chamber are separated by a partition plate 2, allowing the washing aid particles to move between the washing chamber and the storage chamber during and after washing. After the washing operation is completed, the particles are temporarily stored in the storage chamber, reducing the number of washing aid particles in the washing chamber. This makes it easier for people to separate the washing aid particles from the cleaned shoes, facilitating subsequent handling. In this embodiment, the drum 1 is rotatably connected to the body of the shoe washing equipment by a variable frequency motor, which drives the drum 1 to rotate. The rest of the structure, except for the drum 1, can be manufactured based on the basic structure of existing shoe washing equipment.

[0037] like Figure 4 As shown, a spiral-structured storage channel 3 is formed inside the storage chamber. A receiving port connected to the storage channel 3 is opened on the partition plate 2. Several material-blocking protrusions 4 are distributed in a ring array on the inner peripheral wall of the drum 1. Liquid inlet and outlet holes 5 are opened on the peripheral wall of the drum 1 only at the receiving port. The liquid inlet and outlet holes 5 are only opened at the receiving port, so that when the shoe washing equipment cleans the shoes, the added clean water or washing liquid overflows into the drum 1 from the liquid inlet and outlet holes 5. During washing, as the drum 1 rotates under the motor, the clean water or washing liquid flows in the drum 1. Combined with the friction between the washing aid particles and the surface and cavity of the shoes, the shoes can be cleaned without dead angles. At the same time, the several material-blocking protrusions 4 distributed in a ring array on the inner wall of the drum 1 move in a circular motion when the drum 1 rotates. Under the resistance and pushing action of the material-blocking protrusions 4 when the drum 1 rotates, the washing aid particles are intensified to "rub" between the washing aid particles and the shoes, thereby improving the cleanliness of the shoes.

[0038] Furthermore, during the dehydration and collection of washing aid particles, since the inlet and outlet holes 5 are only set at the receiving port, the washing liquid and washing aid particles under the action of gravity in the rotating drum 1 are located between the two material blocking protrusions 4, and flow towards the inlet and outlet holes 5 under the action of water flow. Under the action of the rotating drum 1 squeezing the washing aid particles, the washing aid particles pass through the receiving port and move into the storage channel 3, so that the washing aid particles are efficiently collected when the washing is completed. Moreover, the single drainage point can increase the number of times the shoes tumble in the drum 1, so that the washing aid particles in the shoe cavity come out from the shoe cavity and are collected in the storage channel 3 under the action of reciprocating tumbling. Since the storage channel 3 has a spiral rotating structure, the rotation remains unchanged during dehydration, thus preventing the washing aid particles from falling out of the storage chamber.

[0039] like Figure 3 and Figure 4 As shown, a triangular-shaped receiving guide 6 is raised on the side of the separator plate 2 facing away from the receiving compartment. Specifically, the cross-section of the receiving guide 6 is an obtuse triangle with an angle of 120-150°. Several feeding grooves 7 are provided on one side of the receiving guide 6 along the material receiving rotation direction of the roller 1. In this embodiment, when the roller 1 rotates clockwise, the shoe washing inner cylinder is in the washing state, and when the roller 1 rotates counterclockwise, the shoe washing inner cylinder is in the state of collecting washing aid particles. Therefore, at this time, the feeding grooves 7 are located on the side of the receiving guide 6 that rotates counterclockwise.

[0040] The cross-section of the material blocking ridge 4 is an acute triangle. The receiving guide 6 and the material blocking brush 8 are both located between two adjacent material blocking ridges 4. The distance between the tip of the material blocking ridge 4 and the axis of the roller 1 is greater than the distance between the axis of the receiving guide 6 and the material blocking brush 8.

[0041] A material-blocking brush 8 is detachably connected to the inner wall of the drum 1 via bolts, located on one side of the inlet / outlet hole 5 and the receiving guide section 6. The material-blocking brush 8 provides a damping force to prevent the washing particles from leaving the inlet / outlet hole 5. Specifically, when the drum 1 is rotating counterclockwise, the washing particles roll under gravity between the two material-blocking protrusions 4 of the receiving guide section 6. The material-blocking protrusions 4 can limit the washing particles. Based on this, the material-blocking brush 8 set on one side of the receiving guide section 6 can accumulate the washing particles on the side of the receiving guide section 6 where the feeding groove 7 is opened, thereby improving the collection efficiency and cleanliness of the washing particles.

[0042] The roller 1 has a feeding port that communicates with the washing chamber. The side of the roller 1 facing away from the feeding port is recessed towards the washing chamber to form a frustum-shaped recess 9. The receiving channel 3 has a pressure relief hole 10 that passes through the roller 1 near the central axis of the roller 1. The recess 9 on one side of the roller 1, which forms a frustum-shaped structure, can improve the strength of the roller 1 and provide good resistance to deformation when the roller 1 rotates.

[0043] Example 2: A shoe washing method, applied to a shoe washing device equipped with the shoe washing machine inner cylinder described in the example, the cleaning method is as follows:

[0044] For the first soaking, put the cleaning aid granules and the shoes to be cleaned into drum 1, immerse the shoes in the cleaning aid granules, and then pour it into the shoe washing equipment, immersing the shoes and cleaning aid granules in drum 1.

[0045] For detergent cleaning, inject detergent into drum 1, set the washing mode and start the washing process, and drain the wastewater after the washing is finished.

[0046] After dehydration and cleaning, and drainage, the high-speed rotating drum 1 is inserted and pre-dehydrated, then re-injected into the cleaning system for a second rinse.

[0047] After draining and dehydrating, the roller 1 is rotated in the opposite direction until the washing aid particles are collected into the collection channel 3.

[0048] Drying: Remove the shoes one by one from drum 1 and dry them.

[0049] The specific method for draining and dehydrating is as follows: After completing the second rinse, the shoe washing equipment starts the dehydration program, opens the drain valve of the shoe washing equipment, and the washed water flows out to the drain pipe. In the drum 1, a pressure difference is formed with the water flow. At the same time, when the drum 1 rotates slowly in the opposite direction, the washing particles intermittently fall between the two adjacent material blocking protrusions 4, and move towards the inlet and outlet liquid holes 5 with the water flow. Under the rotation of the drum 1, the washing particles and the collection guide 6 are squeezed against each other and enter the spiral structure collection channel 3 for collection.

[0050] Furthermore, during the dehydration and washing step, the drum 1 continues to rotate clockwise. In this state, the wastewater after washing is discharged through the inlet and outlet holes 5, while the washing aid particles remain in the washing chamber, completing the dehydration operation in the dehydration and washing step. Then, when clean water is injected again, washing is performed.

[0051] Example 3:

[0052] The control process of the shoe washing equipment includes:

[0053] Set the washing mode, and according to the type of shoes to be washed, set the washing time, the rotation speed of drum 1, the number of washes, and the soaking time;

[0054] Set the drainage mode, and set the rotation direction of the drum 1 and the speed of the reverse rotation of the drum 1 according to the type of shoes being washed.

[0055] Specifically, the washing time and the rotation speed of drum 1 are set according to the type of shoes being washed:

[0056] For washing board shoes, set the washing time to 15-20 minutes and the rotation speed of drum 1 to 1200 rpm;

[0057] The washing time for sports shoes is set to 20-25 minutes, and the rotation speed of drum 1 is set to 1200-1400 rpm. Specifically, in the drainage mode, as in Embodiments 1 and 2, drum 1 is kept rotating counterclockwise. While drum 1 is rotating counterclockwise for dehydration, the variable frequency motor is controlled to drive the drum speed to maintain the counterclockwise rotation speed of drum 1 at 200-400 rpm. This allows the washing aid particles to move with the water flow towards the inlet and outlet ports as the washing liquid is discharged at low speed. Under the mutual squeezing force, they are collected into the collection channel 3. Since the inlet and outlet ports 5 are only opened on the peripheral wall of drum 1 near the collection port, the washing aid particles entering the collection channel 3 can be moved towards the axis position along the spiral structure within the collection channel 3. Excess washing is also discharged through the pressure relief hole, improving the collection rate of washing aid particles and reducing the workload of manually sorting shoes and washing aid particles.

[0058] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
