[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-7 This utility model provides a kitchen appliance control panel that is resistant to oil and dirt adhesion. It includes a kitchen disinfection cabinet body 1 and a door panel 2 that is rotatably connected to the front of the kitchen disinfection cabinet body 1 by a hinge. A receiving cylinder 3 is fixedly connected to the side of the kitchen disinfection cabinet body 1 by bolts. A cover plate is provided at the top of the receiving cylinder 3. The receiving cylinder 3 and the control panel are on the same axis. A positioning post 6 is rotatably connected to the inside of the receiving cylinder 3 by a bearing. A keyway is opened on the surface of the positioning post 6. A polyvinyl chloride film roll is wound around the surface of the positioning post 6, and the free end of the polyvinyl chloride film roll penetrates through the surface of the receiving cylinder 3 and covers the surface of the control panel.
[0020] To prevent oil stains from appearing on the control panel surface during use of the kitchen disinfection cabinet 1, a roll of polyvinyl chloride (PVC) film is wrapped around the surface of the positioning post 6. One end of the PVC film roll can be inserted into the keyway on the surface of the positioning post 6 to increase the tensile strength of the PVC film roll. Then, the free end of the PVC film roll is passed out from the inside of the receiving cylinder 3. Because the receiving cylinder 3 and the control panel are on the same axis, the PVC film roll can be laid flat on the surface of the control panel, thereby protecting the surface of the control panel and preventing oil stains from directly adhering to the surface of the control panel. When removing oil stains, simply tear off the section of PVC film that is stained with oil.
[0021] It should be noted that kitchen disinfection cabinets use far-infrared heating tubes inside the cabinet to heat the interior, rapidly raising the temperature to a certain level (usually 100℃-125℃) and maintaining it for more than 15 minutes. The high temperature denatures and inactivates the proteins of pathogenic microorganisms, thereby killing bacteria, viruses and other microorganisms.
[0022] It should be noted that polyvinyl chloride film has the characteristics of good adhesion, good elasticity, high transparency, and can be tightly adhered to objects of various shapes, with excellent wrapping properties.
[0023] In this utility model, two guide rails 4 are symmetrically fixedly connected to the front of the kitchen disinfection cabinet body 1, and the two guide rails 4 are symmetrically arranged on the upper and lower sides of the control panel. The guide rails 4 have a U-shaped structure, and the two ends of the guide rails 4 are located on the two sides of the kitchen disinfection cabinet body 1, and one end of the guide rails 4 is connected to the opening of the receiving cylinder 3. The upper and lower ends of the polyvinyl chloride film are respectively attached to the two guide rails 4. The two guide rails 4 are rotatably connected to the corresponding positions of the screen via a rotating shaft. The two sides of the polyvinyl chloride film are located between the magnetic blocks 5 and the guide rails 4. Iron plates are set at the corresponding positions of the guide rails 4 and the magnetic blocks 5.
[0024] To prevent wrinkles from forming due to misalignment when the PVC film covers the control panel, which could cause the control panel to become unresponsive, two guide rails 4 limit the two sides of the PVC film when the free end of the PVC film roll is pulled out from the inside of the receiving cylinder 3, ensuring that it always maintains the same axis as the control panel. When the PVC film is attached to the control panel, the magnetic block 5 rotates on the surface of the guide rail 4 via a rotating shaft, causing the magnetic block 5 and the guide rail 4 to clamp the PVC film, thereby positioning the PVC film and preventing it from falling off due to external factors such as wind.
[0025] In this utility model, the end of the guide rail 4 away from the receiving cylinder 3 is rotatably connected to the positioning plate 16 via a torsion spring shaft. The kitchen disinfection cabinet body 1 is fixedly connected to the corresponding position of the positioning plate 16 with a fixing plate 10. The side of the positioning plate 16 facing the fixing plate 10 is fixedly connected to the pressure block 11 via a spring. The fixing plate 10 and the pressure block 11 are provided with a positioning groove 12 at the corresponding position. The pressure block 11 is inserted into the inside of the positioning groove 12.
[0026] When the PVC film is placed on the surface of the control plate, it prevents the free end of the PVC film from swinging, so that the free end of the PVC film is inserted between the fixed plate 10 and the positioning plate 16. The positioning plate 16 will cover the surface of the fixed plate 10 due to the torsion spring shaft. The pressure block 11 will press the free end of the PVC film into the interior of the positioning groove 12, thereby realizing the control of the free end of the PVC film.
[0027] In this utility model, a number of insert rods 14 are fixedly connected to the surface of the positioning plate 16, and the surface of the fixing plate 10 is provided with an equal number of slots 13 at positions corresponding to the insert rods 14, with the insert rods 14 inserted into the slots 13.
[0028] When the PVC film needs to be replaced, flip up the magnetic block 5 and the positioning plate 16, and then pull the free end of the PVC film. The new PVC film will replace the PVC film with oil stains. After the replacement is completed, the PVC film is positioned by the positioning plate 16 and the magnetic block 5. When the positioning plate 16 presses the free end of the PVC film, the insertion rod 14 will penetrate the PVC film and insert into the inside of the slot 13. Because the PVC film is penetrating, it is easy to tear off, so the oil-stained part of the PVC film can be torn off.
[0029] It should be noted that in this application, the magnetic block 5 is a neodymium iron boron permanent magnet, while the patch that attracts the magnetic block 5 is made of ferritic stainless steel, thereby achieving magnetic attraction.
[0030] In this utility model, an elastic worm gear 8 is provided inside the receiving cylinder 3. One end of the elastic worm gear 8 is fixedly connected to the positioning post 6, and the other end of the elastic worm gear 8 is in contact with the inner wall of the receiving cylinder 3. Several limiting grooves 7 are evenly opened in a ring shape inside the receiving cylinder 3. A positioning disk 9 is fixedly connected to the end of the elastic worm gear 8 away from the positioning post 6. The positioning disk 9 is inserted into the limiting groove 7 and is slidably connected to the receiving cylinder 3.
[0031] To ensure the PVC film remains taut during stretching, the positioning post 6 rotates inside the receiving cylinder 3 when the PVC film is stretched. The elastic worm gear 8 is stretched and deformed due to the rotation of the positioning post 6. When the elastic worm gear 8 is stretched to its limit, the positioning disk 9 is driven to slide from the inside of one of the moving limiting grooves 7 into the inside of another limiting groove 7, thereby adapting to the length of the PVC film roll. While the positioning disk 9 is moving, the elastic worm gear 8 always has a winding force, thus ensuring that the PVC film remains taut during stretching.
[0032] In this utility model, a baffle plate 15 is fixedly connected to the front of the kitchen disinfection cabinet body 1. The baffle plate 15 is located below the control panel and above the door panel 2. The baffle plate 15 has an arc-shaped structure and the concave surface faces upward.
[0033] The existing kitchen disinfection cabinet 1 has a certain temperature inside. Every time the door panel 2 is opened, hot air leaks out. The baffle 15 can prevent the hot air from directly contacting the polyvinyl chloride film, thereby avoiding the shrinkage of the polyvinyl chloride film.
[0034] The use of this utility model involves the following steps: S1: To prevent oil stains from appearing on the control panel surface during the use of the kitchen disinfection cabinet 1, a PVC film roll is wrapped around the surface of the positioning post 6. One end of the PVC film roll can be inserted into the keyway on the surface of the positioning post 6 to increase the tensile strength of the PVC film roll. Then, the free end of the PVC film roll is passed out from the inside of the receiving cylinder 3. Because the receiving cylinder 3 and the control panel are on the same axis, the PVC film roll can be laid flat on the surface of the control panel, thereby protecting the surface of the control panel and preventing oil stains from directly sticking to the surface of the control panel. When removing oil stains, simply tear off the section of PVC film with oil stains. S2: To prevent wrinkles from forming due to misalignment when the PVC film covers the control panel, which could cause the control panel to become unresponsive, when the free end of the PVC film roll is pulled out from the inside of the receiving cylinder 3, the two guide rails 4 will limit the two sides of the PVC film, ensuring that it always maintains the same axis as the control panel. When the PVC film is attached to the control panel, the magnetic block 5 rotates on the surface of the guide rail 4 through the rotating shaft, so that the magnetic block 5 and the guide rail 4 clamp the PVC film, thereby positioning the PVC film and preventing it from falling off due to external wind or other factors. S3: When the PVC film is placed on the surface of the control plate, it is positioned to prevent the free end of the PVC film from swinging, so that the free end of the PVC film is inserted between the fixed plate 10 and the positioning plate 16. The positioning plate 16 will cover the surface of the fixed plate 10 due to the torsion spring shaft. The pressure block 11 will press the free end of the PVC film into the interior of the positioning groove 12, thereby realizing the control of the free end of the PVC film. S4: When the PVC film needs to be replaced, flip up the magnetic block 5 and the positioning plate 16, and then pull the free end of the PVC film. The new PVC film will replace the PVC film with oil stains. After the replacement is completed, the PVC film is positioned by the positioning plate 16 and the magnetic block 5. When the positioning plate 16 presses the free end of the PVC film, the insertion rod 14 will penetrate the PVC film and insert into the inside of the slot 13. Because the PVC film is penetrated, it is easy to tear off, so the oil-stained part of the PVC film can be torn off. S5: In order to keep the PVC film taut when it is stretched, the positioning post 6 will rotate inside the receiving cylinder 3 when the PVC film is stretched. The elastic worm 8 will be stretched and deformed due to the rotation of the positioning post 6. When the elastic worm 8 is stretched to its limit, the positioning disk 9 will be driven to slide from the inside of the moving limiting groove 7 into the inside of another limiting groove 7, thereby adapting to the length of the PVC film roll. When the positioning disk 9 moves, the elastic worm 8 always has a winding force, so that the PVC film is always taut when stretched. S6: The existing kitchen disinfection cabinet 1 has a certain temperature inside. Every time the door panel 2 is opened, hot air leaks out. The baffle 15 can prevent the hot air from directly contacting the polyvinyl chloride film, thereby avoiding the shrinkage of the polyvinyl chloride film.
