Description

Technical Field

[0001] This utility model relates to a furnace door liner and a baking oven. Background Technology

[0002] The semi-airtight seal between the oven cavity opening (also called the oven mouth) and the oven door (i.e., an oven door gasket with a certain degree of ventilation) is a consumable accessory. The oven door gasket consists of an elastic mesh of stainless steel wire and a fiberglass cloth tube sleeved on the mesh. The oven door gasket is placed at the junction of the oven body and the oven door by multiple hooks. The mesh is elastic to ensure that the cross-section of the fiberglass cloth tube is approximately circular.

[0003] The shortcomings of the above-mentioned prior art are that the fiberglass cloth tube is made of fiberglass braiding, and fiberglass debris is easily generated during the installation and use of the furnace door gasket. Fiberglass debris poses a certain safety hazard to the human body. How to avoid the generation of fiberglass debris during the installation and use of the furnace door gasket is a technical problem to be solved in this field. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an oven door liner and oven, which has a simple structure and can avoid the generation of fiberglass debris during product installation and use.

[0005] To solve the above-mentioned technical problems, this utility model provides a furnace door liner, including a fiberglass cloth tube; a foamed sponge is filled inside the fiberglass cloth tube; the foamed sponge is foamed and molded in one go inside the fiberglass cloth tube and fills the inner cavity of the fiberglass cloth tube; the surface of the fiberglass cloth tube has a skin integrally formed with the foamed sponge, and the skin has puncture holes distributed on it to achieve air permeability.

[0006] A preferred embodiment is that the puncture holes are evenly distributed along the circumference of the fiberglass cloth tube and penetrate the fiberglass cloth tube radially to facilitate air permeability of the furnace door gasket.

[0007] The foamed sponge is foamed and formed in one go inside the fiberglass cloth tube and fills the inner cavity of the fiberglass cloth tube to elastically support the fiberglass cloth tube, so that the cross-section of the fiberglass cloth tube is circular, thereby eliminating the need for the stainless steel wire pipe network required by the prior art.

[0008] The expansion ratio of the foamed sponge during foaming is selected based on the requirements for semi-airtightness and elasticity of the furnace door gasket.

[0009] This utility model provides an oven that uses the aforementioned oven door liner and hooks. The hooks include a rhomboid head and a paperclip-shaped base connected to the bottom of the head. The paperclip base is fixed to a connecting plate, and the bottom of the connecting plate is provided with barbs. The heads of multiple hooks are inserted into corresponding mounting holes on the edge of the oven opening. The barbs corresponding to each hook are inserted into the fiberglass cloth tube and are located in the foam sponge to fix the oven door liner to the oven opening.

[0010] Preferably, the oven door liner is distributed in a U-shape on the edge of the oven opening so that the oven door liner matches the size of the oven opening.

[0011] This utility model has positive effects: (1) The new structure of the furnace door gasket of this utility model utilizes the foaming material of the foamed sponge. During the foaming process, the foaming material overflows from the surface of the fiberglass tube and forms a skin. Then, the skin of the foamed sponge completely covers the fiberglass tube, so as to avoid the generation of fiberglass debris during the use and installation of the product. At the same time, the elastic foamed sponge is used to fill the fiberglass tube to elastically support the fiberglass tube, so that the cross-section of the fiberglass tube is circular, and replaces the stainless steel elastic pipe network set in the fiberglass tube in the prior art, so that the material cost of the product is comparable to that of the prior art; the size and distribution density of the puncture holes are obtained through experiments according to the requirements of the furnace door gasket for semi-airtightness. (2) When installing the furnace door gasket, first insert the heads of multiple hooks into the corresponding mounting holes on the edge of the oven opening, and then insert the furnace door gasket into the barbs corresponding to each hook to complete the installation. This eliminates the need for manufacturers to install multiple hooks on the furnace door gasket before the product leaves the factory, reducing production steps and lowering production costs. At the same time, the installation of the furnace door gasket is also more convenient. Attached Figure Description

[0016] See Figure 1-4The furnace door liner of this embodiment includes: a fiberglass cloth tube 1; a foamed sponge 2 filled inside the fiberglass cloth tube 1; the foamed sponge 2 is foamed and molded in one piece inside the fiberglass cloth tube 1, filling the inner cavity of the fiberglass cloth tube 1; the surface of the fiberglass cloth tube 1 has a skin 2-1 integrally formed with the foamed sponge 2, and the skin has puncture holes distributed on it to achieve air permeability. The puncture holes are evenly distributed along the circumference of the fiberglass cloth tube 1 and penetrate the fiberglass cloth tube 1 radially.

[0017] The size and distribution density of the puncture holes were obtained through experiments based on the requirements of the furnace door lining for semi-air tightness.

[0018] The foamed sponge is foamed and formed in one go inside the fiberglass cloth tube and fills the inner cavity of the fiberglass cloth tube to elastically support the fiberglass cloth tube, so that the cross-section of the fiberglass cloth tube is circular, thereby eliminating the need for the stainless steel wire pipe network required by the prior art.

[0019] The expansion ratio of the foamed sponge during foaming is selected based on the requirements for semi-airtightness and elasticity of the furnace door gasket.

[0020] During the foaming process, the foaming material overflows from the surface of the fiberglass tube and forms a skin. The skin of the foam then completely covers the fiberglass tube to prevent the generation of fiberglass debris during product use and installation.

[0021] The preferred foaming materials for foamed sponges are polyurethane, polyethylene, polyvinyl chloride, or polypropylene. During the foaming process, the sponge surface is in direct contact with the mold or the external environment, and heat is rapidly dissipated, resulting in a surface temperature lower than the interior temperature. This temperature difference allows the surface reaction to reach the curing conditions more quickly, forming a dense skin. Example 2
