Description

[0001] The present invention relates to an automatic washing method for sports shoes,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic washing machine for washing and drying a soiled running shoes and a method of operating the same.

It is common to use a general automatic washing machine that performs washing by generating swirling and vibration in a washing tub by rotating a bottom surface and a part of a side surface in a cylindrical washing tub in which detergents and water are introduced. This is a simple method of using an automatic washing machine type device that automatically cleans cloths and clothes. In recent years, various types of laundry structures to be introduced into the washing tub are being developed in order to prevent the sneakers from being disturbed and to improve the washing efficiency have.

In addition, it is common to use a hot-air drying apparatus using an electric heating wire and a blowing fan for quick drying of running shoes, and a stand-type dryer considering aesthetic aspects has been continuously developed from a simple dryer of a hair dryer type.

Sneakers are made of cloth, sponge, synthetic leather, etc. They have the advantage of being able to work more freely than other shoes, so they have the advantage of giving great activity to the human body, but they are structured to absorb sweat which occurs during frequent activities There is also the disadvantage that it is easily contaminated by the activity of the human body. Therefore, when you want to use sneakers effectively, you must consider the hygiene of sneakers.

Washing and drying of running shoes for hygiene of athletic shoes in general households is carried out in a troublesome way separate from automatic washing of general clothes which is flexible form. First, wipe the outer surface, rub it well with water, brush and detergent, wash the inside and outside of the sneaker, then put it on a shady shade and dehydrate and dry for about 2 days. In other words, the automation is not done, and each sneaker is washed by hand. In this way, the washing of sneakers has a disadvantage that the hands of the human being are much more in the washing process than the washing of the clothes which are well-automated, and the drying condition is difficult and the drying time is very long. On the other hand, the method using the automatic washing machine for clothes has a disadvantage that the inside of the washing machine can be easily contaminated due to the washing of the soiled sneakers.

In the present invention, washing and rinsing processes are performed by first supplying water and vibration by using piping bent as a trainer so as to insert a sneaker into an unpleasant sneaker washing which requires a lot of human hands for washing and takes a long time for drying , An automatic washing and drying apparatus that performs a drying process by supplying hot air in a secondary manner is used and the washing, rinsing and drying processes are automatically performed in an appropriate order, I suggest.

Since the present invention makes it easy to manage sneakers that are difficult to wash and dry, it provides convenient laundry for housewives to save housework hours and reduces the time required for sneaker management for athletes, And to provide a more hygienic outdoor activity environment for young people during the growing season.

The washing process of ordinary sneakers uses water, detergent, and brush to rub the outer and inner surfaces of the sneakers to generate bubbles, thereby removing the adsorbed contaminants and dust. The detergent components remaining in the sneakers are washed with water The rinsing process can be largely divided into the rinsing process. These processes may be performed by hand, and handled at a shop for athletic laundry, a simple mechanical (mechanical) wash using an electric brush or a hose nozzle may be performed. There may also be a rotary washing-type laundry washing method in which a sneaker is washed by vortex and vibration generated by rotation of a pulsator or a cylindrical washing tub itself in a washing tub using an electric motor.

The washing method of the present invention is a vibration washing method using purely vibration. The vibration washing method means that washing is performed by transmitting only vibration without movement of the object to be washed. When applying an alternating current (current) to an electromagnet without using a vortex or a wave generated by a washing drum or a rotating plate or rotating the rotating surface connected to the electric motor It is a method of washing shoes by using the vibration generated by it. In the vibration washing mode, the sneakers are supported by the inner frame of the washing tub 104 and stopped in the washing water. The vibration is similar to the foot shape in the human body supporting the sneakers from the inside thereof, And is transmitted from the piping (piping). The sneaker 103 is immersed in water and supplied with water, detergent and vibration through a bent pipe 155 supporting the inside of the sneaker. Here, the vibration may be supplied from the mechanically connected rotary shaft 162 and the electric motor from the outside of the washing tub, and may be applied to an alternating electric power such as an electromagnet fixed to the inside of a pipe 154 for supporting a running water, Or may be supplied from the inside by the vibration generated by the electromagnetic induction action caused by the electromagnetic induction. The water is supplied automatically by closing the automatic water valve 127 connected to the faucet. The detergent may be pre-filled in the water supply tank 125 in the case of the powder detergent, or may be automatically supplied in an appropriate amount by connecting the automatic valve 123 in the case of the liquid detergent.

The washing course of sneakers is selected prior to entering the automatic sneaker washing process. Depending on the contamination condition of the sneakers, it is necessary to decide how many times to perform the basic vibration washing process and the vibration rinsing process once, Select whether you want to be or not. There is no recommendation or restriction on the use of materials that can be selected in the manufacture of shoe sneakers beforehand by various sneaker manufacturers, so the temperature of the hot air that can be applied to each sneaker may vary. Therefore, the low-temperature drying and the hot-air drying process may be separately selected and the hot air drying process may be excluded or the temperature of the hot air supplied through the heat line 136 may be limited by using the temperature sensor 137.

The bottom of the sneaker is the part that comes into direct contact with the race track, floor, mud, etc. If contamination is severe, rinse the running water or brush with gritty, sticky contaminants on the floor and on the surface before putting it in the automatic sneaker washing machine so that the prewash can be done.

The inner surface of the sneaker is made of fabric and sponge, and is a soft part that comes into direct contact with the body. Opening the lid 101 of the sneaker washing machine and turning the sneaker upside down, the sneaker is put on the pair of pipes 155 bent toward the front side of the inside of the washing machine as the sneaker is put on the feet as shown in FIG. Then, when the lid is closed, the elastic surface 102 under the lid abuts against the floor of the running shoes to support the running shoes from above.

The washing machine of this sneaker washing machine is made of waterproof material such as plastic, stainless steel, ceramic, etc. The inner size is enough to immerse a pair of sneakers. At the bottom of the slope of the washing machine, There is an automatic valve 112 in which a control line is connected to the washing machine control unit 105 between the main drain 111 and the drain pipe connected to the main drain. The auxiliary drain pipe 114 is located at a position higher than the bottom of the sneaker, and the auxiliary drain pipe is connected to the main drain pipe and the lower end of the main drain valve 112 to discharge overflowing water during operation.

In this sneaky washing machine, there is no special consideration in terms of the temperature of the washing water because general household water is used as the water supply. However, if hot water is to be used in the laundry to increase the washing effect, the hot water of the desired temperature Must be installed.

There may be various forms of deformation within the scope of not impairing the purpose of the sneaky washing method using this vibration. For example, when the individual positions of the heat exchanger 134, the blower 135, the heating line 136, the vibration generator 163, and the like are disposed on the side, top, or front surface of the washing tub, There may be variations such as addition of auxiliary devices to be assisted or omitted. Also, in a standard washing machine, several pairs of main pipes are provided in a washing machine body, and by increasing the number or volume of the washing machines, The present invention can be expanded and implemented in the form of a redundant washing tub which can be washed.

When the timer 106 of the control unit to which the operation sequence shown in FIG. 9 is applied is aligned and the operation button 107 is pressed to start washing, the washing tub 104 starts to be filled with the washing water. The washing water spouting from the inside of the pair of pipes 156 which sandwich the sneakers is pushed out from the sneaker and filled in the washing tub. FIG. 3 shows the water supply flow of the washing water starting from the water supply tank.

In the water supply tank 125 in which the washing water for washing is supplied, water and detergent are supplied into the sneak through the main pipe 154.

If the liquid detergent 122 is to be used, the liquid detergent bottle 121 in the upper portion of the water supply tank 125 to which the detergent inlet pipe 124 and the automatic valve 123 are connected is pre-filled. When the water supply is started, the control unit sends a control signal to open the automatic valve 123, and the liquid detergent is mixed with the washing water to start the surfactant action in the washing tub.

If a powder detergent is to be used, a method of opening the lid of the water supply tank 125 and directly introducing an appropriate amount of the powder detergent may be used. From the moment of watering for washing, the powder detergent begins to melt and mix with the washing water, and bubbles start to be generated by the supply of washing water, surfactant and vibration inside the sneaker.

After the washing water and the detergent are filled to the extent that the bottom surface of the sneakers facing upwards is immersed in water, the water supply is stopped and vibration is performed. The vibration in the washing tub supplies vibration through the main pipe 154 made of a hard material. The vibration of the main pipe (164), which is repeated at a rate of several to several tens of hertz (Hz) per second in the sneaker, increases the surfactant action of the detergent contained in the water, so as to be washed by dripping water falling down to the bottom of the waterfall The soft cloth inside the sneaker and the sponges that are absorbed by the sponge are peeled off and spread out into the water.

The generation of the vibration is caused by the vibration generating device and can be supplied from the rotational force of the electric motor as shown in Fig. 2, and the vibration generated when the alternating current is supplied to the coil wrapping the electromagnet fixed to the pipe may be used. It is also possible to use a gear or a rotary cam.

The transmission position of the vibration can be transmitted to the intermediate position 164 of the main pipe through the watertight hole in the rear or side of the washing tub as shown in FIG. 8, and the position of the main pipe 154 Only when the vibration generator is completely waterproofed and insulated and at the same time the size is made small, it is possible to use a wire connected to the main pipe 154 and a bent wire The vibration device may be operated from the inside of the true main pipe 155. The above examples are examples that do not deviate greatly from the form of the various vibration generating apparatuses of the washing using the vibration of the present invention.

The present invention can be applied to various types of vibration generating apparatuses at various positions other than the vibration generating apparatuses shown in the drawings of the present invention and connected to the main piping.

When sufficient time has elapsed to wash the running shoes, the supply of detergent, water and vibration is stopped and the main drain 111 is opened to empty the contaminated washing water in the washing tub. Then, through the water supply pipe again, clean water not containing detergent is filled. After the washing tub is filled, the vibration is resumed, and at the same time, clean water is continuously supplied from the piping 155 inside the sneaker so that the rinsing process of washing the detergent and the contaminated water from the running shoes is performed. The rinsing water, which is overflowed to the washing tub and overflows gradually, is appropriately drained through the auxiliary drain port 114 prepared in advance in the upper portion of the washing tub. When the detergent component is cleanly removed from the running shoes, the vibration is stopped and the main drain is opened as shown in FIG. 4 to drain all the rinsing water from the washing tub.

In the present invention, the washing machine controller 105 can be preliminarily inputted so that the washing and rinsing processes are repeatedly performed a predetermined number of times. The washing and rinsing courses can be selected so as to be repeatedly performed about 1 to 2 times of washing and 1 to 3 times of rinsing depending on the size of the sneaker or the degree of contamination like an ordinary household automatic washing machine.

Drying of sneakers in real life is usually done by drying one or two days in a shady place where windy weather is good. Recently, a method of drying sneakers using hot air has been continuously developed. Sneakers are usually made up of multiple layers of synthetic leather, natural leather, rubber, plastic, sponge, fiber and so on. In the case of regular clothing made of cotton and cloth, it is recommended to disinfect in sunlight containing ultraviolet rays, but sneakers are not recommended because they may cause discoloration of the material due to ultraviolet rays. In general, clothes made of cloth are exposed to hot heat of sunlight to increase the temperature of laundry to encourage the evaporation of moisture. However, since the sneaker may be deformed in a hot environment, it is dried slowly in the shade It is recommended to preserve it. The temperature of the air which is suitable for the quick drying of the running shoes should not be too hot because the material should not be deformed and the evaporation of water should be high.

The faster the flow of air, the other element of air that affects the drying, the faster the drying of the sneakers. Also, the remaining factor is the humidity in the air. If the density of the water vapor contained in the flowing air, that is, the humidity is low, the moisture is quickly taken out from the outer surface of the running shoes, so that the drying speed can be increased.

The sneaker washing machine of the present invention rapidly circulates air having a temperature range of 15 ° C to 90 ° C to an air blower to increase the drying speed. The air outside the washing machine having an average temperature of about 15 ° C is directly used without being processed or blown out from the inside 156 of the sneaker after the heated air is sucked into the outside air sucked through the heating device. The air to be directly contaminated in the room to be contaminated is passed through a filter 131 to remove the dust and the like in order to preserve the washing treatment state. The air to be inhaled and the air to be exhausted are cross- By increasing the relative humidity by lowering the exhaust air temperature, the water vapor is condensed and discharged. At the same time, the heat utilization efficiency is improved by using a heat exchange system capable of recovering heat from the discharged exhaust gas. Fig. 5 shows the structure of the drying device. Fig. 6 shows the flow of the intake air, and Fig. 7 shows the flow of the exhaust.

Applying heat during the drying process is essential because it increases the drying efficiency and can reduce the number of bacteria by sterilizing action. However, continuing to supply heat throughout the drying process can be a waste of energy use efficiency. There is a considerable difference between the heating efficiency of the heating wire that generates heat and the dynamic efficiency of the motor that produces the air flow, and the air flow is generated by using a blowing fan rather than using a heater to heat the air to be discharged Is advantageous in terms of saving energy because the amount of energy used per hour is small. Accordingly, in the embodiment of the present invention, after the start of drying by the flow of the air, the hot air including the heat is flowed at the time when the outer surface of the sneaker is dry, thereby raising the temperature of the sneaker, Reduce the waste of energy by programming the time sequence in advance in the washer control to repeatedly use the method of drawing to the surface and drying the surface again with fast air flow.

Also, a rapid hot-air drying course is added to the operation panel of the washing machine control unit 105 so that continuous heating is performed to dry thick sneakers. On the contrary, for the case sensitive to temperature such as sneezing material easily burns to heat, a low-temperature drying course is also added in which the blower is operated without applying heat and the outside air is supplied to dry. For this function, a temperature control circuit of about 90 DEG C using the temperature sensor 137 and a time control circuit for controlling the low temperature drying time and the hot air drying time by a timer are connected to the heating wire control switch, And adds it to the control unit 105.

In the present invention, when the rinsing process is completed, the main drain port 111 is opened to drain all the rinsing water in the washing machine, and the air stream is supplied to the inside of the running shoes by operating the blower 135 to perform low temperature drying at 20 ° C. After the inner surface of the soft running shoes is sufficiently dried due to the air flow, the speed of the blower is lowered and the temperature of the air supplied to the inside of the running shoes is increased to 90 ° C by supplying electricity to the heating wire 136 in the air pipe. When the inside of the sneaker is fully heated, the movement of the water vapor molecules in the sneaker material becomes active and escapes from the surface of the sneaker. At this time, the fan 135 is driven to evaporate moisture on the surface of the soft sneaker by low temperature drying. 6 shows the flow of the intake air and the air flow.

The intake air filter, the heat exchanger, the electric heater, and the like shown in the embodiment of the present invention may have a detailed shape change by other types of intake filters, heat exchangers, electric heaters, and the like.

After the low-temperature drying and the hot-air drying are repeated, the hot water is continuously added to heat the hair at 90 ° C to sterilize the remaining bacteria. This method is a low-temperature type sterilization method in which almost all bacteria are sterilized when they are kept at a temperature of 80 ° C or more. In addition, the extension of the present invention for maintaining the temperature of 120 ° C or higher for perfect sterilization only needs to raise the temperature control range by the temperature sensor 137 from 90 ° C to 120 ° C. The extension of such pasteurization must be carried out according to the constituent material of the running shoes. The bottom of the sneaker, ie the material of the outsole, is rubber type and it may be very weak to the heat. Please refer to the instruction manual of the sneakers after checking whether it is possible or impossible. Almost all rubber materials forming the bottom of running shoes, such as natural rubber types and synthetic rubber types of styrene butadiene rubber (BR), butadiene rubber (BR), chloroprene rubber (CR), nitrile butadiene rubber (NBR) It should be remembered that deformation begins. In the case of synthetic rubbers of butyl rubber (IIR), ethylene propylene rubber (EPDM), chlorosized polyethylene rubber (CSM), acrylic rubber (ACM, ANM), fluorine rubber (FKM / FPM) There are few examples that are used to endure high temperatures or to run shoes.

At the end of the hot air drying process, the low temperature drying blowing indoor air rapidly lowers the temperature of the running shoes, terminates the entire process, and causes a buzzer or a bell sound to be recognized by the washing machine user.

The advantage of the present invention is that it does not require human touch during the washing process of the contaminated sneakers, but can be performed non-stop at the same time by washing, rinsing and drying process by simply pressing the operation button. A typical user can work on other important things without having to worry about having to put the sneakers into the running shoes washing machine, manipulating the laundry control, pressing the action button, and so on. In the case of a housewife, it is not necessary to dirty the hands and it is possible to pay more attention to other housework. In the case of adolescents in the growing season, it can bring the right body development to the knee and waist by not bending the floor on the floor. If you are athletes, you will be able to enjoy longer hours of exercise because you can relax after exercise.

Although the sneaker washing machine of the present invention is designed only for running shoes, it is also applied to various shoes such as sneakers made of soft cloth and sponge, slipper shoes, canvas shoes, rough synthetic leather, solid shoes, This is possible. However, many shoe types, such as shoes, casual shoes, boots, sandals, etc., are not made of materials that are easily deformed by water or heat, or shoes which are susceptible to vibration due to the manufacturing method such as adhesion.
