Description

Technical Field

[0001] This technical solution relates to the field of oven accessories technology, specifically to a sealing and mounting mechanism for an oven's lighting lamp. Background Technology

[0002] Ovens are categorized into electric ovens, gas ovens, and steam ovens. Steam ovens, in particular, are based on traditional ovens but incorporate a steam system. This system primarily consists of a water tank, an evaporator, and a series of conduits. When the user selects the steam function, water from the tank flows to or is drawn into the evaporator, which then activates to generate steam. This steam is then transported through the conduits to the oven cavity to heat and bake the food. Therefore, a certain amount of steam will remain inside the oven cavity.

[0003] Existing steam ovens typically have lighting fixtures installed inside the oven cavity; however, most of these fixtures are directly exposed inside the oven. When the oven is operating, steam can easily leak from the fixture's mounting holes and condense into water droplets on the light-emitting element, potentially causing a short circuit.

[0004] To prevent steam leakage inside the inner cavity, most steam ovens on the market currently use a sealing ring between the outer shell of the light and the inner cavity. However, most of these sealing rings are made of rubber or silicone. When a steam oven is steaming or baking, the internal temperature can often reach over 200 degrees Celsius. Such temperatures can cause the sealing ring to age and affect its sealing effect. Furthermore, when a steam oven performs a high-temperature self-cleaning process, the internal steam temperature can reach over 400 degrees Celsius. Such high temperatures can further cause the sealing ring to age or melt, thus affecting its sealing effect. Summary of the Invention

[0005] The purpose of this technical solution is to provide a sealing installation mechanism for the lighting lamp of an oven, which uses a sealing element made of high-temperature resistant material to seal the gap between the lighting lamp and the side wall of the mounting hole, thereby improving the poor sealing effect of existing silicone or rubber sealing elements in high-temperature environments.

[0006] The purpose of this technical solution is achieved as follows:

[0007] An oven lighting fixture sealing and mounting mechanism includes: an inner liner with a mounting hole; a lighting fixture having a mounting portion and a sealing portion, the mounting portion being inserted into and connected to the mounting hole; and a sealing element made of a high-temperature resistant material, installed between the inner liner and the lighting fixture; wherein the sealing element has an abutment portion one, a connecting portion and an abutment portion two; the abutment portion one is disposed at one end of the connecting portion, and the abutment portion two is disposed at the other end of the connecting portion; when the lighting fixture is installed into the inner liner, the abutment portion one abuts against the edge of the mounting hole, and the abutment portion two abuts against the sealing portion, thereby sealing the gap between the lighting fixture and the side wall of the mounting hole.

[0008] Preferably, the high-temperature resistant material used to make the seal is a metal or graphene.

[0009] Preferably, the seal is made of stainless steel.

[0010] Preferably, the sealing element is in the shape of a hollow frustum, the connecting part forms the side wall of the hollow frustum, the first abutting part forms one end of the hollow frustum, and the second abutting part forms the other end of the hollow frustum.

[0011] Preferably, one end face of the abutment portion is parallel to and fits against the edge of the mounting hole; the other end face of the abutment portion is parallel to and fits against the end face of the sealing portion.

[0012] Preferably, the connecting part is elastic. When the lighting lamp is installed into the inner liner, the connecting part undergoes elastic deformation, so that the first abutting part abuts against the edge of the mounting hole, and the second abutting part abuts against the end face of the sealing part.

[0013] Preferably, both the first abutment and the second abutment are elastic. When the lighting lamp is installed into the inner liner, both the first abutment and the second abutment undergo elastic deformation, such that the first abutment abuts against the edge of the mounting hole, and the second abuts against the end face of the sealing part.

[0014] Preferably, the first abutment, the connecting part, and the second abutment are integrally formed.

[0015] Preferably, the sealing part is a boss provided on the outer periphery of the lighting lamp, and the abutting part abuts against the end face of the boss.

[0016] Preferably, the mounting part is provided with a threaded part, which is threadedly connected to the mounting hole; the top or side wall of the inner liner is provided with a mounting surface inclined toward its center, the mounting surface is provided with the mounting hole, and the abutting part abuts against the mounting surface located at the edge of the mounting hole.

[0017] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0018] The sealing element designed in this technical solution is made of high-temperature resistant material. The sealing element can prevent the sealing element from melting due to excessive temperature inside the inner liner. At the same time, the sealing element has a first abutment part, a connecting part, and a second abutment part. During the installation process, when the sealing element is placed between the mounting hole and the sealing part, the first abutment part abuts against the edge of the mounting hole, and the second abutment part abuts against the sealing part, thereby sealing the gap between the side wall of the mounting hole and the light, thus ensuring the sealing effect, preventing high-temperature water vapor inside the inner liner from entering the light, ensuring the normal operation of the steam oven and the stable operation of the light.

[0029] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings. See also Figures 1-7 .

[0030] Example 1:

[0031] An oven lighting lamp sealing installation mechanism includes: an inner liner 1, a lighting lamp 2, and a sealing element 3. The inner liner 1 is installed inside the oven cavity for baking food. An installation hole 11 is provided on the top or side wall of the inner liner 1. The lighting lamp 2 has an installation part 21 and a sealing part 22. The installation part 21 is inserted into and connected to the installation hole 11. The sealing element 3 is made of a high-temperature resistant material and is installed between the inner liner 1 and the lighting lamp 2. The sealing element 3 has an abutment part 32, a connecting part 31, and an abutment part 33. The abutment part 32 is located at one end of the connecting part 31, and the abutment part 33 is located at the other end of the connecting part 31. When the sealing element 3 is fitted onto the installation part 21 and the lighting lamp 2 is installed into the inner liner 1, the abutment part 32 abuts against the edge of the installation hole 11, and the abutment part 33 abuts against the sealing part 22, thereby sealing the gap between the lighting lamp 2 and the side wall of the installation hole 11.

[0032] like Figure 4 The top or side wall of the inner liner 1 is inclined toward its center with a mounting surface 12, that is, the mounting surface 12 is inclined toward the center of the internal cavity of the inner liner 1. The mounting surface 12 is provided with a mounting hole 11, and the abutment part 32 abuts against the mounting surface 12 located at the edge of the mounting hole 11.

[0033] When the seal 3 is used in a steam oven, the internal temperature of the steam oven can reach more than 450 degrees Celsius when it is steaming or baking or high-temperature self-cleaning. At this time, the melting point of the high-temperature resistant material used in the seal 3 is not lower than 450 degrees Celsius, so that the seal 3 will not age or deform due to high temperature.

[0034] When the seal 3 is used in a regular oven, the oven is baking food and the internal temperature of the inner cavity can reach more than 200 degrees Celsius. At this time, the high temperature resistant material used in the seal 3 has a melting point of no less than 200 degrees Celsius, so that the seal 3 will not age or deform due to high temperature.

[0035] The high-temperature resistant material used to make the seal 3 is either a metal or graphene material.

[0036] Furthermore, the high-temperature resistant material used to make the seal 3 is stainless steel, a nickel-based alloy, or a cobalt-based alloy, preferably stainless steel.

[0037] Combination Figures 4-6The sealing element 3 is in the shape of a hollow frustum. The connecting part 31 forms the side wall of the hollow frustum, the first abutment part 32 forms one end of the hollow frustum, and the second abutment part 33 forms the other end of the hollow frustum. The connecting part 31 is inclined, that is, the included angle α between the connecting part 31 and the first abutment part 32 is an obtuse angle, and the included angle β between the connecting part 31 and the second abutment part 33 is an obtuse angle. This ensures the stability of the first abutment part 32 abutting against the edge of the mounting hole 11 and the stability of the second abutment part 33 abutting against the sealing part 22 when the sealing element 3 is installed between the inner liner 1 and the lighting lamp 2 and the sealing part 22 and the mounting hole 11 are close to each other.

[0038] Combination Figure 4 and Figure 6 The end face of the first abutment part 32 is parallel to and fits against the edge of the mounting hole 11, ensuring the sealing between the first abutment part 32 and the edge of the mounting hole 11; the end face of the second abutment part 33 is parallel to and fits against the end face of the sealing part 22, ensuring the sealing between the second abutment part 33 and the sealing part 22.

[0039] The connecting part 31 has the characteristic of elastic deformation, that is, it is elastic. When the lighting lamp 2 is installed into the inner liner 1, the connecting part 31 undergoes elastic deformation, so that the first abutment part 32 abuts against the edge of the mounting hole 11, and the second abutment part 33 abuts against the end face of the sealing part 22, thereby sealing the gap between the mounting hole 11 and the lighting lamp 2, preventing high-temperature water vapor in the inner liner 1 from entering the lighting lamp 2 through the gap, and ensuring the normal operation of the lighting lamp 2.

[0040] The first abutment part 32, the connecting part 31 and the second abutment part 33 are integrally formed by stamping, welding or extrusion.

[0041] Combination Figure 4 and Figure 7 The sealing part 22 is a boss provided on the outer periphery of the lighting lamp 2. The abutting part 33 abuts against the end face of the boss. The diameter of the boss is larger than the diameter of the mounting part 21, and the diameter of the boss is larger than the diameter of the mounting hole 11.

[0042] like Figure 7 As shown, a threaded portion 211 is provided on the outer side wall of the mounting portion 21, and the threaded portion 211 is threadedly connected to the mounting hole 11.

[0043] The lighting lamp 2 has several anti-slip parts 23 arranged around its circumference. The anti-slip parts 23 are anti-slip grooves, anti-slip protrusions, anti-slip dots, or protrusions perpendicular to the rotation direction of the lighting lamp 2, which are used to help the user tighten the lighting lamp 2 onto the inner tube 1.

[0044] The lighting lamp 2 includes a housing and a light-emitting element. The housing is made of a transparent or semi-transparent material, such as transparent glass or transparent plastic. The housing has a cavity for housing the light-emitting element, which is a light bulb or a diode, etc.

[0045] Example 2:

[0046] The design scheme of this embodiment is basically the same as that of Embodiment 1, except that:

[0047] The first abutment part 32 and the second abutment part 33 have the characteristic of elastic deformation, that is, they are elastic. When the lighting lamp 2 is installed into the inner liner 1, both the first abutment part 32 and the second abutment part 33 undergo elastic deformation, so that the first abutment part 32 abuts against the edge of the mounting hole 11, and the second abutment part 33 abuts against the end face of the sealing part 22.

[0048] Example 3:

[0049] The design scheme of this embodiment is basically the same as that of Embodiment 1 or Embodiment 2, except that:

[0050] The first abutment part 32, the connecting part 31 and the second abutment part 33 are all elastic. When the lighting lamp 2 is installed into the inner liner 1, the first abutment part 32, the connecting part 31 and the second abutment part 33 all undergo elastic deformation, so that the first abutment part 32 abuts against the edge of the mounting hole 11 and the second abutment part 33 abuts against the end face of the sealing part 22.

Those skilled in the art should understand that this technical solution is not limited to the above embodiments.
