Definitions
- the present invention relates to a shoe care device, and more specifically, to a shoe care device in which treatment of shoes is performed by air circulation.
- Shoes can become wet from the wearer's sweat, external contaminants, rain, snow, etc. Wearing such shoes is not only uncomfortable for the wearer, but in such a condition, bacteria can grow in the shoes and give off a bad smell.
- Korean Patent Publication No. 10-2021-0158763 discloses a “SHOE MANAGEMENT DEVICE,” and a shoe sterilization treatment device according to the same comprises a storage section, a first supply section, a third supply section, etc.
- the storage section forms a storage space for storing shoes on the inside
- the first to third supply sections are configured to guide fluid and supply it to the inside of shoes stored in the storage space.
- the time and cost required for drying shoes can be reduced by smoothly supplying fluid to the inside of the shoe.
- Korean Patent No. 1037245 discloses an “Apparatus for sterilization disposal of shoes,” and the shoe sterilization disposal device according to the patent includes a main body, an ultraviolet emitting module, a deodorizing module, etc.
- shoes are placed in the sterilization chamber of the main body, and the ultraviolet emitting module is operated to remove bacteria and odors from the shoes. Then, the air inside the sterilization chamber is sucked in through the air pipe, passes through the deodorizing module, and is discharged outside the main body through the exhaust port.
- the deodorizing module includes a deodorizing column made of materials such as zeolite, activated carbon, and charcoal, and the deodorizing column removes contaminants from the air discharged from inside the main body to the outside.
- air from which moisture has been removed by a deodorizing module including zeolite, activated carbon, etc. can be discharged to the outside of a shoe sterilization treatment device.
- Korean Patent Publication No. 10-2000-0009653 discloses a “shoe cabinet for sanitization,” and the shoe cabinet according to the invention comprises a main body, a far-infrared ray radiating portion, a circulation fan, an air circulation passage, a sanitary filter portion, etc.
- the shoes can be sanitized by dehumidifying, sterilizing, and deodorizing using far infrared rays and a filter while being stored.
- the sanitary filter section is filled with highly absorbent materials such as charcoal, so that it absorbs moisture as the air passes through it, filters out bacteria, and captures substances that cause bad odors.
- air is circulated by a circulation fan inside a shoe cabinet, and a sanitary filter part is placed on the air circulation path to remove bacteria and odors in the air.
- the present invention aims to solve the above problems of a shoe care device that treats shoes by circulating air flow.
- the present invention aims to provide a shoe care device that can dehumidify and deodorize shoes using a dehumidifying agent so as to refresh the shoes, and can also regenerate the used dehumidifying agent so that the performance for shoe treatment can always be appropriately maintained.
- the present invention aims to provide a shoe care device having a circulating airflow structure that dehumidifies the air inside an inner cabinet where shoes are placed using a dehumidifier and supplies the dehumidified air back into the inner cabinet, thereby preventing the air used to dehumidify and deodorize shoes from being exposed to the user.
- the present invention aims to provide a shoe care device that enables steam treatment of shoes to be performed more appropriately, thereby enabling optimal treatment efficiency of shoes without functional damage.
- a shoe care device configured to dehumidify and deodorize shoes using a dehumidifying unit, and to regenerate the used dehumidifying unit.
- the dehumidifying unit is arranged in a module chamber so as to capture moisture and bacteria in the air being blown, and to heat the dehumidifying unit in the module chamber so as to be regenerated.
- a shoe care device is configured such that air used for dehumidifying and deodorizing shoes has a circulating airflow structure inside the shoe care device. Specifically, a connecting path through which air circulates is formed between each of the suction ports and nozzles arranged inside the inner cabinet.
- a shoe care device is configured so that steam is sprayed not only to the outside of the shoe but also to the inside of the shoe when steaming the shoe.
- steam supplied to the inner cabinet is configured so that it is sprayed not only to the outside of the shoe through the upper outlet of the nozzle duct but also to the inside of the shoe through the lower outlet of the nozzle.
- a shoe care device can supply steam from a steam generator to a part of a drying air duct and move to a nozzle duct and nozzle.
- a shoe care device can supply steam from a steam generator to a steam separator and then move it to a drying air duct through a steam connection pipe.
- a shoe care device has a drying air duct positioned above a steam separator so that steam can move upward.
- a shoe care device performs a steam cycle between a first regeneration cycle and a first drying cycle, and while the first regeneration cycle is being performed, air passing through a dehumidifying section is introduced into the receiving space to increase the temperature of the receiving space.
- a shoe care device can perform a steam treatment while the damper blocks the dry air outlet of the module housing.
- a shoe care device can discharge condensate inside a drying air duct to a condenser while the damper opens the drying air outlet of the module housing.
- a shoe care device may be formed with a nozzle including a nozzle body and a nozzle protrusion.
- a shoe care device may have a nozzle duct installed forward from the rear wall of the inner cabinet.
- a shoe care device may have a discharge slope formed to guide the direction of steam sprayed from the lower discharge port toward the rear of the inner cabinet.

- the amount of steam distributed to the upper outlet, auxiliary outlet, and lower outlet can be divided into 3:3.5:3.5.
- the injection pressure of the steam injected from the lower discharge port (821) is relatively lowered, so that the condensate flowing into the shoe due to the injection pressure of the steam can be minimized.
- the shoe care device (1) sprays steam supplied to the inner cabinet (100) in a dispersed manner from the upper discharge port (811) and the auxiliary discharge port (824) before being sprayed into the interior of the shoe, so that the spray pressure of the steam from the lower discharge port (821) is relatively low, thereby minimizing the inflow of condensate into the interior of the shoe.
