Description

Technical Field

[0001] This invention relates to the field of chef's shoes, and in particular to a waterproof and breathable perforated shoe specifically designed for chefs. Background Technology

[0002] Chefs spend long hours standing in the kitchen work area, where the environment is characterized by water accumulation, splattered oil, and steam. This causes feet to sweat and become hot, placing stringent demands on the breathability, waterproofing, and slip resistance of work shoes. While some chefs choose Crocs due to their lightweight and breathable properties, the open perforations in the upper and shoe body create a completely open structure. During kitchen work, water and oil from the floor easily seep into the shoes and come into direct contact with the feet, significantly reducing comfort and increasing the risk of slipping due to wet feet. Furthermore, food scraps, water stains, and other debris can easily enter the shoes, fostering bacterial growth.

[0003] Currently, similar footwear on the market generally suffers from the technical drawback of not being able to balance breathability and protection. If large-diameter pores are retained to ensure breathability, it is impossible to prevent water, oil, and foreign objects from entering the kitchen. If a closed upper is used to improve waterproofing and stain resistance, it will lead to poor air circulation inside the shoe, exacerbating the problem of stuffiness and sweating in the feet of chefs after long hours of work. This fails to meet the comprehensive needs of chefs for work shoes that are breathable, waterproof, stain-resistant, and slip-resistant.

[0004] Therefore, there is an urgent need to develop a pair of clogs that are suitable for chefs' work environment, have good breathability, and can effectively prevent water, oil, and foreign objects from entering. Summary of the Invention

[0005] This invention provides a waterproof and breathable perforated shoe specifically for chefs, to solve the problem that existing perforated shoes cannot meet the comprehensive needs of chefs for work shoes that are breathable, waterproof, stain-resistant, and slip-resistant.

[0006] The present invention adopts the following technical solution: A waterproof and breathable perforated shoe for chefs includes an upper and a midsole. The upper is composed of an upper body and a waterproof upper accessory. The upper body and the midsole are integrally molded by injection molding. The waterproof upper accessory is attached to the upper body and has multiple ventilation holes. A waterproof and breathable fabric is bonded to the bottom of the waterproof upper accessory. The above-mentioned midsole is provided with multiple longitudinal ventilation holes that penetrate the midsole. The midsole includes an upper midsole layer and a lower midsole layer stacked under the upper midsole layer. A first waterproof accessory is sandwiched between the upper midsole layer and the lower midsole layer. The first waterproof accessory is provided with convection holes corresponding to the ventilation holes. A waterproof and breathable fabric is adhered to one side of the first waterproof accessory. or, The aforementioned midsole has multiple horizontally penetrating ventilation channels, and the upper surface of the midsole has through holes connecting the ventilation channels. A receiving groove is opened along the periphery of the midsole, and the opening of the aforementioned ventilation channel corresponds to the bottom of the receiving groove. A second waterproof accessory is adapted to cover the receiving groove. The second waterproof accessory has a round hole corresponding to the aforementioned ventilation channel, and a waterproof and breathable fabric is adhered to one side of the second waterproof accessory.

[0007] Furthermore, the diameter of the exhaust channel gradually increases from the middle of the bottom to both sides, and the cross-section of the exhaust channel is elliptical.

[0008] Furthermore, the sole of the shoe is reinforced with anti-slip rubber sheets at both the forefoot and heel, and the surface of the anti-slip rubber sheets is provided with anti-slip patterns.

[0009] Furthermore, the aforementioned waterproof and breathable fabric has multiple overflow holes along its periphery for overflowing adhesive, and the overflow holes are evenly distributed along the edge of the waterproof and breathable fabric.

[0010] Furthermore, the convection holes are provided with multiple inclined plates, with gaps between adjacent inclined plates.

[0011] Furthermore, the aforementioned inclined panel, the aforementioned first waterproof accessory, and the aforementioned second waterproof accessory are all made of TPU material.

[0012] Furthermore, the bottom edge of the aforementioned receiving groove is provided with an adhesive strip, which corresponds to the edge of the aforementioned second waterproof accessory.

[0013] Furthermore, the preparation of the aforementioned first waterproof accessory includes the following steps: Step 1: Use a laser device to make multiple overflow holes in the waterproof and breathable fabric. The overflow holes are arranged and distributed along the edge of the first waterproof accessory. Step 2: Open the upper mold of mold A. Mold A has a cavity for preparing the main body of the first waterproof accessory. Inject TPU material into the cavity of mold A, cool and shape it to obtain the above-mentioned main body of the first waterproof accessory. Step 3: Place the first waterproof accessory body obtained in Step 2 into the lower mold of Mold B. Hang the waterproof and breathable fabric obtained in Step 1 on the upper mold of Mold B. Close Mold B. The upper and lower walls of Mold B clamp the middle part of the first waterproof accessory body and the waterproof and breathable fabric. The edge of the mold cavity of Mold B corresponds to the edge of the first waterproof accessory and the edge of the waterproof and breathable fabric. Inject TPU material into the mold cavity of Mold B. The TPU material penetrates the above-mentioned overflow hole, cools, and is formed. Open Mold B and trim off the waterproof and breathable fabric extending outside the first waterproof accessory. The first waterproof accessory body and the waterproof and breathable fabric are integrally formed in the mold to obtain the first waterproof accessory.

[0014] As can be seen from the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages: 1. The chef's special perforated shoe of the present invention, by providing a waterproof and breathable fabric on the inner wall of the shoe upper, a first waterproof and breathable accessory between the upper and lower layers of the midsole, and a second waterproof and breathable accessory along the perimeter of the sole, forms a comprehensive waterproof and breathable composite protective structure on the upper, sides, and sole of the shoe. The waterproof and breathable fabric of each accessory allows for free air convection inside and outside the shoe, quickly dissipating the heat and sweat generated by the chef's feet during long working hours, keeping the feet dry. At the same time, it can effectively prevent water and oil stains from the kitchen from entering the shoe from all directions, achieving a dual effect of breathability, waterproofing, and stain prevention, and is suitable for the special working environment of the kitchen.

[0015] 2. The waterproof accessories of the clogs of the present invention are designed with convection holes, exhaust holes and round holes corresponding to the original ventilation holes, through holes and exhaust channels of the shoe body. While retaining the original ventilation path of the shoe body, protection is added without obstructing the air circulation inside and outside the shoe, ensuring the breathability effect. Moreover, the diameter of the exhaust channel holes gradually increases from the middle of the sole to both sides, forming a natural slope, which can automatically drain the small amount of water stains and oil stains that accidentally seep into the shoe, further improving the waterproof and stain-resistant performance, avoiding prolonged contact between the chef's feet and water stains and oil stains, and improving wearing comfort and work safety.

[0016] 3. The waterproof base plate and waterproof strip of this invention are both made of TPU material, which is tough, waterproof and oil-resistant, and wear-resistant and scratch-resistant. It can resist the friction of hard objects and the corrosion of oil stains on the kitchen floor. After being combined with waterproof and breathable fabric, the structure is stable and not easily deformed or damaged. The waterproof and breathable fabric has overflow holes around its perimeter, so that the adhesive can be evenly overflowed and cured when the accessories are bonded to the shoe body, which improves the bonding strength and prevents the accessories from falling off during the chef's daily walking and operation, effectively enhancing the durability of the product in the high-intensity use scenario of the kitchen.

[0017] 4. The outsole of this invention features a composite sub-layer with anti-slip patterns, which significantly improves the friction between the outsole and the greasy, wet kitchen floor, effectively preventing chefs from slipping and reducing workplace safety hazards. Meanwhile, the waterproof components are modular composite structures that can be precisely bonded to the shoe body. The manufacturing process is simple, suitable for industrial mass production, and the shoe body is lightweight, minimizing foot strain during prolonged standing work. It is highly practical and perfectly suited to the work requirements of chefs. Attached Figure Description
