The present disclosure generally relates to a gasket, and more particularly, to a gasket including a mesh layer.
Thermal appliances, such as ovens, generally have a cavity (also referred to a “heat capacity room”) and a door configured to cover one end of the cavity. In order to prevent heat inside the cavity from escaping through the space between the cavity and the door when the door is closed, a gasket may be used to fill the space. The gasket may include an inner support and an outer tubular member made of, for example, glass fiber. It is desirable to provide a properly designed structure and configuration of the inner support to support the outer tubular member when the outer tubular member is pressed by other components of the oven such as the door and the cavity.

Provided herein is a gasket including a tubular section with a mesh tube enclosed in the tubular section. The mesh tube may include a plurality of Ω-shaped elements arranged in a spiral fashion extending along an axial direction of the mesh tube. When the tubular section is pressed by an external force, the mesh tube may provide an elastic support to the tubular section. The gasket may also include an extension section integrated with the tubular section and a plurality of fasteners mounted on the tubular section. The gasket may be mounted to a thermal appliance by the plurality of fasteners in association with the extension section.
The positioning elements 105 may be located at different positions of the end 107. For example, at least one positioning element 105 may be located at a corner of the end 107. The positioning elements 105 may be uniformly or randomly distributed on the end 107. As shown in
The body 103 may include a tubular section. The tubular section of the body 103 may be compressible along the radial direction such as to closely attach to the end 107 and the door 108. The fastener 104 may be configured to mount the gasket 102 onto the end 107 via, for example, the positioning element 105. Merely by way of example, the fastener 104 may include a dart portion, and the positioning element 105 may include a hole that accommodates the dart portion of the fastener 104 such that the fastener 104 may attach to the positioning elements 105, thereby mounting the gasket 102 to the end 107. Additionally or alternatively, the fastener 104 and the positioning element 105 may form a coupling structure configured to attach to each other. Exemplary coupling structure may include a bolt, a screw, a nut, an airtight glue, or an airtight adhesive tape.
This description is intended to be illustrative, and not to limit the scope of the present disclosure. Many alternatives, modifications, and variations will be apparent to those skilled in the art. The features, structures, methods, and other characteristics of the exemplary embodiments described herein may be combined in various ways to obtain additional and/or alternative exemplary embodiments. For example, the positioning elements 105 may be arranged on the door 108. The gasket 102 may be mounted on the door 108 when the door 108 is separated from the end 107. However, those variations and modifications do not depart the scope of the present disclosure.
The protection layer 201 may form a tube. The tube may include a hollow cavity that encloses the mesh layer 202 and protects the mesh layer 202 from touching, for example, the door 108 and the end 107 of the thermal appliance 100. As shown in
In some embodiments, the protection layer 201 may be fabricated by braiding a plurality of yarns into a texture. Exemplary textures may include tabby, cross grain, satin weave, or the like, or a combination thereof. The texture may be braided according to a drafting design. Exemplary drafting design may include a straight draft, a skipped draft, a chevron-like draft, a broken draft, a divided draft, or the like, or a combination thereof. Merely by way of example, the protection layer 201 may be braided into satin weave according to a straight draft.
Due to the adverse environmental conditions to which the protection layer may be exposed (e.g., heat and smoke from the heat capacity room 106, long-term compression and repeated flexures from opening and closing the door 108), the plurality of yarns may be made of one or more suitable materials. In some embodiments, the yarns may be made of heat resistant and insulated materials. For example, the plurality of yarns may be made of polymer materials. Exemplary polymer materials may include silicone, polyvinyl chloride (PVC), polyethylene (PE), ethylene vinyl acetate copolymer (EVA), polypropylene (PP), polystyrene (PS), acrylonitrile butadiene styrene acrylonitrile butadiene styrene (ABS), polymethyl methacrylate (PMMA), polyurethane (PU), polyurethane elastomer (UE), polyamide (PA), polycarbonate (PC), polyformaldehyde (POM), polyethylene terephthalate (PET), polyphenylene ether (PPO), polytetrafluoroethylene (PTFE), polyphenylene sulfide (PPS), polyimide (PI), or the like, or a combination thereof. As another example, the plurality of yarns may be made of inorganic materials, for example, ceramic fiber and carbon fiber. Exemplary ceramic fiber may include glass fiber, common aluminum silicate fiber, high aluminum silicate fiber, chromium-doped aluminum silicate fiber, zirconium-doped aluminum silicate fiber, forsterite fiber, silicon dioxide-calcium oxide-magnesium oxide composite fiber, or the like, or a combination thereof. Exemplary glass fiber may include alkali-free glass fiber, medium-alkali glass fiber, or the like, or a combination thereof. As still another example, the plurality of yarns may be made of metals. Exemplary resilient metal wire may include stainless-steel wire, silver wire, or the like, or a combination thereof. In some embodiments, the protection layer 201 may be fabricated by braiding different types of yarns. For example, the protection layer 201 may be fabricated by intertwining glass fiber yarn(s) and metal wire(s).
The protection layer 201 may have an outer surface and an inner surface. At least one of the outer surface and the inner surface may be coated with one or more lubricant materials. The lubricant material coating the outer surface and/or the inner surface may include an inorganic lubricant material or an organic lubricant material. Exemplary inorganic lubricant material may include graphite, graphene, molybdenum disulfide, oxide, or the like, or a combination thereof. Exemplary organic lubricant material may include polytetrafluoroethylene (PTFE), polyethylene (PE), oil, or the like, or a combination thereof. The outer surface and/or the inner surface may be coated through one or more coating techniques. Exemplary coating technique may include a brush coating technique, a rolling coating technique, a spray coating technique, a flame spray coating technique, a plasma spray coating technique, a vacuum deposition technique, a chemical vapor deposition technique, an impregnation coating technique, an ultrasound coating technique, or the like, or a combination thereof. In some embodiments, the coating process may be performed before or after the texture that forms the protection layer 201 is braided. For example, the texture may be fabricated by braiding the yarns that have been coated with a lubricant material. Alternatively, the texture may be fabricated by braiding uncoated yarns firstly and then coating the braided yarns with one or more lubricant materials. Alternatively, the texture may be fabricated by braiding the yarns that have been coated with a lubricant material, and the texture may further be coated with the same or a different lubricant material.
The mesh layer 202 may form a mesh tube that is enclosed in the protection layer 201. The mesh layer 202 may provide an elastic support (e.g., a resilient force) to the protection layer 201 when the protection layer 201 is pressed by, for example, the door 108 and the end 107.
In some embodiments, the mesh layer 202 may be knitted by at least a metal wire. Exemplary metal wires may include a stainless-steel wire, a silver wire, a copper wire, or the like, or a combination thereof. The diameter of the metal wire may be in a range of 0.01 to 1 millimeter. In some embodiments, the diameter of the metal wire may be restricted to a sub-range of 0.01 to 0.05 millimeters, 0.05 to 0.1 millimeters, 0.1 to 0.5 millimeters, 0.5 to 1 millimeter. Merely by way of example, the mesh layer 202 may be knitted by a stainless-steel wire having a 0.1 millimeters.
In some embodiments, the mesh layer 202 may include a plurality of unit elements (e.g., the Ω-shaped element illustrated in
In some embodiments, the unit-element layers of the mesh layer 202 may extend spirally along the axial direction of the mesh layer. For example, two adjacent unit-element layers of the mesh layer 202 may be knitted from a single metal wire, and thus the unit elements in one unit-element layer of the two adjacent unit-element layers may integrate with the unit elements in the other unit-element layer of the two adjacent unit-element layers. Alternatively, at least two unit-element layers of mesh layer 202 may be arranged in a parallel fashion. For example, each of two adjacent unit-element layers of the mesh layer 202 may be knitted from an independent metal wire, and the two adjacent unit-element layers may further twist with each other.
In some embodiments, the gasket 102 may include more than one mesh layer. The mesh layers may be arranged in the manner that the mesh layer having a greater diameter encloses the mesh layer having a smaller diameter. Additionally or alternatively, the gasket 102 may include a first mesh layer having a diameter greater than that of the protection layer 201. The first mesh layer may enclose the protection layer 201, which may enclose a second mesh layer. The first and second mesh layers may be made of the same or different material. The first and second mesh layers may have the same or different type of unit elements. In addition, the configuration of the unit elements of the first and second mesh layers may be the same or different.
The fastener 203 may be configured to mount the gasket 102 on a thermal appliance (e.g., the thermal appliance 100). As shown in
The extension section 211 may integrate with the protection layer 201. In some embodiments, the extension section 211 may be knitted from the same yarns (or the same texture sheet) forming the protection layer 201. For example, the extension section 211 may be knitted from a first portion of a thread of yarn, and the protection layer 201 may be knitted from a second portion of the same thread of yarn. In some embodiments, the extension section 211 and the protection layer 201 may be knitted from different yarns.
As shown in
In some embodiments, the stitches 212 may be made of the same materials as the protection layer 201. For example, both of the protection layer 201 and the plurality of stitches 212 may be made of glass fiber coated with graphite. In some embodiments, the material of the stitches 212 may be different from that of the protection layer 201. For example, the plurality of stitches 212 may be made of glass fiber without the coating of graphite, and the protection layer 201 may be made of glass fiber coated with graphite.
It should be noted that the description regarding the gasket 102 is provided for the purposes of illustration, and not intended to limit the scope of the present disclosure. For persons having ordinary skills in the art, various variations and modifications may be conducted under the guidance of the present disclosure. However, those variations and modifications do not depart the scope of the present disclosure. For example, the extension section 211 may be omitted. As another example, the protection layer 201 and the extension section 211 may be separated by a hot-pressing technique instead of the plurality of stitches 211. As still another example, the protection layer 201 and the mesh layer 202 may be braided form a single layer. However, those variations and modifications do not depart the scope of the present disclosure.
The fastener 203 may be installed on the protection layer 201. For example, the interval between two adjacent fasteners may be a fixed value. Merely by way of example, the interval may be in the range of 1 centimeter to 100 centimeters. In some embodiments, the interval may be restricted to a sub-range of 1-5 centimeters, 5-10 centimeters, 10-20 centimeters, 20-50 centimeters, or 50-100 centimeters. Alternatively, the fastener 203 may be installed on the protection layer 201 in an irregular way. For example, the fasteners 203 may be disposed according to the positions of the plurality of positioning elements (e.g., positioning elements 105 illustrated in
It should be noted that the description regarding the gasket 102 is provided for the purposes of illustration, and not intended to limit the scope of the present disclosure. For persons having ordinary skills in the art, various variations and modifications may be conducted under the guidance of the present disclosure. However, those variations and modifications do not depart the scope of the present disclosure. For example, the protection layer 201 may have a curved face, and the top edge of the protection layer 201 may be a curved line. However, those variations and modifications do not depart the scope of the present disclosure.
The extension section 411 may form a tube, which may have a similar shape to the shape of the protection portion 401. The extension section 411 and the protection portion 401 may be knitted from the same yarns. In this case, the extension section 411 and the protection portion 401 may be separately knitted from different portions of the same yarns and then knitted together.
It should be noted that the description about the gasket 400 is provided for the purposes of illustration, and not intended to limit the scope of the present disclosure. For persons having ordinary skills in the art, various variations and modifications may be conducted under the guidance of the present disclosure. However, those variations and modifications do not depart the scope of the present disclosure. For example, more than one extension sections may be knitted. The more than one extension section may have the same or different diameters. However, those variations and modifications do not depart the scope of the present disclosure.
The fastener 600 may have a base portion 602 and a dart portion 601. The base portion 602 may have a base plane. The dart portion 601 may extend transversely or perpendicularly from the base portion 602 (e.g., the center of the base portion 602).
In some embodiments, the dart portion 601 may be formed by bending one end of a single wire into a first structure. The first structure may include a shape of a rhombus or diamond, a shape of an arc, a shape of a Ω-shaped structure, or an irregular shape. The dart portion 601 may include a free end 603. The free end 603 may bend toward an inner edge of the dart portion 601. In some embodiments, the free end 603 may closely attach to the inner edge of the dart portion 601, which may keep the dart portion 601 from loosening or disbanding and keep the free end 603 from threading through outside of a protection layer that catches the fastener 600.
In some embodiments, the base portion 602 may be formed by bending a free end 604 of the single wire into a second structure. The second structure may have a shape of a paper clip, a shape of a hoop, a shape of a rectangle, a shape of a rhombus, or an irregular shape. Merely by way of example, the base portion 602 may have a shape of a paper clip. The paper clip-shaped base portion may have two long length sides. The dart portion 601 may extend from one of the two long length sides. The long length sides may be connected by a pair of opposing curved sides at two ends of the longer length portions. The second free end 604 may be turned below the base plane of the base portion 602. In some embodiments, the second free end 604 may turn away from the base plane of the base portion 602.
It should be noted that the description regarding the fastener 600 is provided for illustration purposes, and not intended to limit the scope of the present disclosure. For persons having ordinary skills in the art, various variations and modifications may be conducted under the guidance of the present disclosure. More descriptions regarding the fastener 600 may be found in, for example, U.S. Pat. No. 9,447,628, the contents of which are incorporated herein by reference.
The plurality of Ω-shaped elements 710 may be knitted from at least one metal wire. Exemplary metal wire may include a stainless-steel wire, a silver wire, a copper wire, or the like, or a combination thereof. The Ω-shaped element 710 may include a bottom part 720 and a head part 730. The bottom part of a Ω-shaped element in a unit-element layer may integrate with the bottom part of an adjacent Ω-shaped element in the same unit-element layer. The head part of a Ω-shaped element in a unit-element layer may thread through the head part of a corresponding Ω-shaped element in an adjacent unit-element layer. As shown in
The plurality of unit-element layers of the mesh layer 700 may have a tubular configuration and form a tube. In some embodiments, the unit-element layers may extend spirally along the axial direction of the tube. For example, two adjacent unit-element layers may be knitted from a single metal wire, and thus the Ω-shaped elements in one of the two adjacent unit-element layers may integrate with the Ω-shaped elements in the other unit-element layer of the two adjacent unit-element layers. In some embodiments, the unit-element layers may be arranged in a parallel fashion. For example, two adjacent layers may be knitted from two different metal wires respectively, and the Ω-shaped elements in one unit-element layer may thread through the Ω-shaped elements in the other unit-element layer to form the mesh layer 700.
The mesh layer 700 may provide an elastic support to a protection layer (e.g., the protection layer 201), which encloses the mesh layer. The strength of the elastic support may depend on the state of the mesh layer 700. For example, the mesh layer 700 may have a tensional state and a compressive state. As used herein, the tensional state refers to stretching the mesh layer 700 along the axial direction. The compressive state refers to compressing the mesh layer 700 along the axial direction. In a unit length along the axial direction of the mesh layer 700, the number of Ω-shaped elements of the mesh layer 700 in the tensional state may be less than the number of Ω-shaped elements of the mesh layer 700 in the compressive state. Thus, the mesh layer 700 in the compressive state may provide a greater elastic support along the radial direction than the mesh layer 700 in the tensional state. In some embodiments, the strength of the elastic support provided by the mesh layer 700 in the compressive state may be multiple times of the strength of the elastic support provided by the mesh layer 700 in the tensional state. For example, the ratio between the two strengths of the elastic support provided by the mesh layer 700 in the compressive state and the tensional state may be in a range of 1.5 to 2.5.
It should be noted that the description regarding the mesh layer 700 is provided for illustration purposes, and not intended to limit the scope of the present disclosure. For persons having ordinary skills in the art, various variations and modifications may be conducted under the guidance of the present disclosure. For example, the Ω-shaped element may be replaced by another unit element with another proper shape. However, those variations and modifications do not depart the scope of the present disclosure.
The mesh layer 700 may have different lengths along the axial direction in the tensional state and the compressive state. For example, the length of the mesh layer 700 in the tensional state may be multiple times of the length of the mesh layer 700 in the compressive state. Merely by way of example, the tensional length of the mesh layer 700 under a stretching force (e.g., 3N) may be a first value. The compressive length of the mesh layer 700 under a compressive force (e.g., 3N) may be a second value. The ratio between the first value and the second value may be in a range of 2 to 4.
In some embodiments, when enclosed in a protection layer (e.g., the protection layer 201), different portions of the mesh layer 700 may be in different states. For example, the portion of the mesh layer 700 disposed at a corner of a thermal appliance may be in the compressive state. Another portion of the mesh layer 700 disposed of away from the corner of the thermal appliance may be in the tensional state.
In some embodiments, different states of the mesh layer may be sustained in the mesh layer 700 by the fasteners described elsewhere in the disclosure. For example, a portion of the mesh layer 700 may be kept in a compressive state by at least two fasteners. The at least two fasteners may restrict the portion of the mesh layer from stretching along the axial direction of the mesh layer 700.
In 1010, a tubular fabric may be acquired. In some embodiments, the tubular fabric may be knitted from a plurality of yarns as described in connection with, for example, the protection layer 201.
In 1020, the tubular fabric may be divided into at least two parts. Merely by way of example, the at least two parts may be formed by stitching the tubular fabric along a line parallel to the axis of the tubular fabric. The at least two parts may include a first tube and a second tube. The first tube may have a similar shape to the shape of the protection layer 201, and the second tube may have a similar shape to the shape of the extension section 211.
In 1030, a mesh tube may be inserted into one of the at least two parts of the tubular fabric. In some embodiments, the mesh tube may be similar to the mesh layer 202 illustrated in
In 1040, one or more fasteners may be installed on the tubular fabric. The one or more fasteners may be installed on the one of the at least two parts of the tubular fabric, which may enclose the mesh tube. The one or more fasteners may be similar to the fastener 203 illustrated in
It should be noted that the above description is merely provided for the purposes of illustration, and not intended to limit the scope of the present disclosure. For persons having ordinary skills in the art, multiple variations or modifications may be made under the teachings of the present disclosure. However, those variations and modifications do not depart from the scope of the present disclosure. For example, the operation 1020 may be unnecessary and omitted. The tubular fabric may be knitted to include at least two separate parts which is similar to the gasket 400 illustrated in
