Description

[0001] AN INSULATION FIXING SYSTEM FOR DOMESTIC OVENS AND A METHOD RELATED THERETO

[0002] Technical Field

[0003] The invention relates to an insulation fixing system for domestic ovens and a method related thereto.

[0004] More specifically, the invention relates to an insulation fixing system that ensures the fixing of insulation plates around a cooking chamber by using holders positioned oppositely on a body bottom surface and a fixing element, and a method related thereto.

[0005] State of the Art

[0006] Domestic ovens are appliances that meet basic needs such as cooking, heating, and baking food in kitchens. These ovens, which generally have electric or gas models, offer flexibility to the user with different cooking programs, temperature settings, and timer features. Domestic ovens heat ingredients within a closed cooking chamber during the cooking process. Said cooking chamber is configured to withstand high temperatures and is structured to provide suitable insulation and sealing so that ingredients can be cooked efficiently under the effect of heat and steam. The temperature and humidity balance inside the cooking chamber is of great importance in terms of the quality and safety of the cooking process.

[0007] Insulation plates surrounding the cooking chamber of the ovens are important components used to both increase thermal efficiency and minimize energy loss. These plates are typically produced from materials that are heat-resistant, lightweight, and have high insulation performance. For example, materials such as glass wool, rock wool, or ceramic fiber are widely preferred due to their properties of being able to show resistance against high temperatures and providing low thermal conductivity.

[0008] In connecting the insulation plates to the oven, it is necessary to create a configuration that ensures they fit perfectly onto the surface of the cooking chamber. However, the correct placement and retention of materials in place constitute a technical challenge considering thermal expansion, vibration, and other mechanical effects occurring during cooking.

[0009] In the prior art, various methods are used for fixing insulation plates. Among these are mechanical fastening methods such as metal clips or brackets, heat-resistant adhesives and mastics, riveting, and screwing. Besides these, solutions providing mechanical stability such as compression elements,channel configurations, and cage systems are also widely used. However, these methods may complicate the assembly process and cause the plates to loosen or be displaced overtime. Especially in ovens exposed to high-temperature cycles, the reliability of fixing systems is of great importance.

[0010] KR101690323B1 discloses the fixing of plates using a wire passed under the insulation plates. The main difference with the present invention stems from the structuring and configuration in the method of fixing the insulation plates by the fixing wire. In KR101690323B1, the fixing wire is positioned to wrap the insulation material and the gap from below. To fix this wire, the end portions of the wire are attached to a pair of wire fixing hooks. These hooks are shaped by extending laterally from a heater base and being bent. In this system, the wire surrounds the lower surface of the insulation plates, and its ends hold onto the hooks to ensure the fixing of the plates. In the present invention, however, the fixing system consists of fixing elements placed in specially configured slots on the body of the oven. The fixing wire passes through the first and second slot, grasps the insulation plates from the outside, and ensures that the plates are tightly fixed around the cooking chamber. Unlike KR101690323B1, this system fixes the insulation plates not from below but from the outside and offers a more flexible and modular assembly method via the slots. This difference ensures that our fixing method is more compatible with our production processes while increasing the ease of assembly and the effectiveness in fixing the plates. Furthermore, the compatibility of the wire with the slots is structured to respond better to factors such as thermal expansion. Therefore, the present system is distinctively separated from the fixing method from above presented in KR101690323B1.

[0011] Consequently, there is a need to ensure effective insulation and develop a long-lasting fixing mechanism in current insulation plate configurations. In this context, the fixing system proposed within the scope of this description aims to ensure that the insulation plates are reliably kept in place.

[0064] Detailed Description of the Invention

[0065] The invention relates to an insulation fixing system (1) ensuring the fixing of insulation plates (23.1, 23.2, 23.3, 23.4) around a cooking chamber (22) by using holders (10, 12) positioned oppositely on a body bottom surface (21.2) and a fixing element (11), and a method related thereto.

[0066] While the holders (10, 12), which are among the components of the insulation fixing system (1), have a monolithic configuration formed by operations such as bending, cutting, and pressing of a sheet made of metal in the preferred configuration of the invention, these elements can be provided by being brought together via methods such as screwing, welding, etc., in alternative configurations of the invention. The fixing element (11) is a wire made of metal in the preferred configuration of the invention, but it can be configured in different materials or forms such as strips, etc., in alternative configurations of the invention.

[0067] The insulation fixing system (1) comprises at least one first holder (10), at least one fixing element (11), and at least one second holder (12). The first holder (10) has at least one first slot (10.1) component, and the second holder (12) has at least one second slot (12.1) component. The fixing element (11) contains at least one first portion (11.1), at least one second portion (11.2), at least one third portion (11.3), at least one fourth portion (11.4), and at least one fifth portion (11.5).

[0068] While detailed descriptions of the invention are being provided, references indicated in the figures will be cited for a better understanding of explanations such as direction, axis, alignment, etc. Here, according to the figures; the first axis (C) denotes the horizontal axis dividing the body bottom surface (21.2) and the cooking chamber (22) symmetrically from the middle when viewed from the oven door (24). At the same time, right and left directions (when viewed from the oven door (24)) are indicated as invariant in the figures (Figures 2, 8, and 9).In the preferred configuration of the invention, the first holder (10) is formed by bending a rectangular cross-section having a certain width, length, and wall thickness on the right edges of the body bottom surface (21.2) when viewed from the oven door (24), from a bending point in a first direction (A) (upwards), in other words, towards the cooking chamber (22) (Figures 4, 6). A first slot (10.1), configured as a circular cutout having a certain diameter through which the first portion (11.1) can pass, is structured at a point close to the upper part of the first holder (10). The first slot (10.1) provides the connection of the fixing element (11) to the first holder (10) and to the body bottom surface (21.2) to which the first holder (10) is connected. The fixing process takes place when the first portion (11.1) of the fixing element (11) passes through the first slot (10.1). In the preferred configuration of the invention, there are three first holders (10) with a certain distance between them. More specifically, the first holder (10) is positioned on the body bottom surface (21.2) and includes at least one first slot (10.1).

[0069] In the preferred configuration of the invention, the fixing element (11) is configured such that a first portion (11.1) and a fifth portion (11.5) have a hook-like curved form, and said portions (11.1, 11.5) are joined by a wire made of metal. In alternative configurations of the invention, the fixing element (11) can be configured in different forms such as rope, etc., non-metal, or strip, etc. The fixing element (11) is formed by at least one first portion (11.1) having a curved structure providing connection with the first holder (10) by passing into said first slot (10.1); a second portion (11.2) as a continuation of said first portion (11.1), extending up to a third portion (11.3) and ensuring stability by seating on the bottom plate (23.1) and the first side plate (23.2); at least one third portion (11.3) as a continuation of said second portion (11.2), extending up to a fourth portion (11.4) and ensuring stability by seating on the top plate (23.4); a fourth portion (11.4) as a continuation of said third portion (11.3), extending up to a fifth portion (11.5) and ensuring stability by seating on the second side plate (23.3) and the bottom plate (23.1); and a fifth portion (11.5) having a curved structure, as a continuation of said fourth portion (11.4), providing connection with a second holder (12) by passing into a second slot (12.1) positioned in the second holder (12).

[0070] In the preferred configuration of the invention, the second holder (12) is formed by bending a rectangular cross-section having a certain width, length, and wall thickness on the left edges of the body bottom surface (21.2) when viewed from the oven door (24), from a bending point in a first direction (A) (upwards), in other words, towards the cooking chamber (22) (Figures 5, 7). A second slot (12.1), configured as a circular cutout having a certain diameter through which the fifth portion (11.5) can pass, is structured at a point close to the upper part of the second holder (12). The second slot (12.1) provides the connection of the fixing element (11) to the second holder (12) and to the body bottom surface (21.2) to which the second holder (12) is connected. The fixing process takesplace when the fifth portion (11.5) of the fixing element (11) passes through the second slot (12.1). In the preferred configuration of the invention, there are three second holders (12) with a certain distance between them. More specifically, the second holder (12) is positioned oppositely with said first holder (10) relative to a first axis (C) and includes at least one second slot (12.1).

[0071] In another embodiment of the invention, the structures of the first and second holder (10, 12) and the first and second slot (10.1, 12.1) can be configured in different geometries (rectangular, elliptical, etc.) and numbers, and this should not be understood as a limitation of the invention.

[0072] The oven (20) denotes the element configured to cook food. The body (21) is the outermost layer forming the outer chassis of the oven (20) and surrounding the cooking chamber (22). The body (21) is in a rectangular prism geometry and its front part remaining behind the oven door (24) is open.

The body (21) has a front wall (21.1) forming the front part of the body (21), at least one body bottom surface (21.2) forming the base (bottom) of the body (21), a body (21) top surface forming the ceiling (top) of the body (21), body (21) lateral surfaces forming the right and lateral surface of the body (21) when viewed from the oven door (24), and a body (21) rear surface forming the rear of the body (21). The body bottom surface (21.2) is the surface forming the bottom surface of the body (21) where the cooking chamber (22) and the bottom plate (23.1) are placed.

[0073] The cooking chamber (22) is in a rectangular prism geometry and its front part remaining behind the oven door (24) is open. The cooking chamber (22) has a bottom surface (22.1) forming the base (bottom) of the cooking chamber (22), a first side surface (22.2) forming the right lateral edge of the cooking chamber (22), a second side surface (22.3) forming the left lateral edge of the cooking chamber (22), a top surface (22.4) forming the ceiling (top) of the cooking chamber (22), and at least one rear surface (22.5) forming the rear of the cooking chamber (22). The cooking chamber (22) is generally made of materials such as enamel coating, stainless steel, aluminum, etc.

[0074] The bottom plate (23.1) refers to the insulation plate placed between the cooking chamber (22) bottom surface (22.1) and the body bottom surface (21.2); the first side plate (23.2) to the first side surface (22.2); the second side plate (23.3) to the second side surface (22.3); and the top plate (23.4) to the top surface (22.4). These plates (23.1, 23.2, 23.3, 23.4) prevent heat loss by surrounding the cooking chamber (22) and ensure the provision of an efficient cooking process. The body (21) surrounds the cooking chamber (22) and the plates (23.1, 23.2, 23.3, 23.4).

[0075] The oven door (24) is connected to the front wall (21.1) so as to correspond to the front wall (21.1) and provides access to the cooking chamber (22) upon being opened / closed by the user.During assembly, the first operation is the seating of the bottom plate (23.1) onto the body bottom surface (21.2). Following this, the connection of the cooking chamber (22) with the body bottom surface (21.2) is provided by the process of seating the cooking chamber (22) bottom surface (22.1) onto said bottom plate (23.1). After this process, the first side plate (23.2) is seated onto the first side surface (22.2) and the second side plate (23.3) onto the second side surface (22.3). With the seating of the top plate (23.4) onto the top surface (22.4), the placement of the plates (23.1, 23.2, 23.3, 23.4) is completed. The process of fixing the plates (23.1, 23.2, 23.3, 23.4) begins with the passing of the first portion (11.1) into the first slot (10.1) found in the first holder (10). Following this, the second portion (11.2) is seated onto the first side plate (23.2). Subsequently, the third portion (11.3) is seated onto the top plate (23.4). After the seating of the fourth portion (11.4) onto the second side plate (23.3), the fixing process is completed with the passing of the fifth portion (11.5) into the second slot (12.1) found in the second holder (12). In the preferred configuration of the invention, the fixing process of the plates (23.1, 23.2, 23.3, 23.4) is performed using three first holders (10), three fixing elements (11), and three second holders (12).

[0076] The invention is an insulation fixing system (1) for an oven (20) having a body (21) surrounding a cooking chamber (22) wherein foods to be cooked are placed, such that there is a bottom plate (23.1) resting on a bottom surface (22.1) of the cooking chamber (22), a first side plate (23.2) resting on a first side surface (22.2) thereof, a second side plate (23.3) resting on a second side surface (22.3) thereof, and a top plate (23.4) resting on a top surface (22.4) thereof between them; a front wall (21.1) in the form of a frame forming the front part of the body (21); and an oven door (24) connected to the front wall (21.1) and providing access to the cooking chamber (22); and it ensures the fixing of the plates (23.1, 23.2, 23.3, 23.4) to the oven (20) with the aid of at least one first holder (10) having a first slot (10.1) and at least one second holder (12) having a second slot (12.1), positioned oppositely on the side regions of the body bottom surface (21.2), and at least one fixing element (11) passing through the first slot (10.1) and second slot (12.1), and resting on the plates (23.1, 23.2, 23.3, 23.4) from the outside to ensure the fixing of the plates (23.1, 23.2, 23.3, 23.4), in order to ensure that the insulation plates (23.1, 23.2, 23.3, 23.4) remain fixed around the cooking chamber (22) in an oven (20) configured to cook food. This fixing process is provided by a method including the process steps of: seating a bottom plate (23.1) onto the body bottom surface (21.2), seating the cooking chamber (22) bottom surface (22.1) onto the bottom plate (23.1), seating the first side plate (23.2) onto the first side surface (22.2) and the second side plate (23.3) onto the second side surface (22.3), seating the top plate (23.4) onto the top surface (22.4), passing the first portion (11.1) into the first slot (10.1) found in the first holder (10), seating the second portion (11.2) onto the first side plate (23.2), seating the third portion (11.3) onto the top plate (23.4), seating the fourth portion (11.4) onto the second sideplate (23.3), and passing the fifth portion (11.5) into the second slot (12.1) found in the second holder (12).

[0077] The invention meets the need for innovative apparatuses that fix insulation plates (23.1, 23.2, 23.3, 23.4) in domestic ovens (20) while simultaneously facilitating assembly. The insulation fixing system (1) can ensure a more efficient assembly by facilitating production processes in addition to increasing the general durability of the oven (20) and supports the long-lasting use of the oven (20).
