Description

Technical Field

[0001] This application relates to the field of kitchen appliances, and more specifically, to an oven. Background Technology

[0002] Ovens in this technology use heating elements to bake food. When repairing the lower heating element, the oven must be disassembled to expose the inner cavity to remove the lower heating element cover assembly and replace the element. This disassembly process also requires removing the insulation from the inner cavity, which may affect the overall performance of the oven. Therefore, this type of oven structure makes replacing the lower heating element cumbersome and requires a certain level of disassembly skill, thus increasing the difficulty of repairing or replacing the lower heating element.

[0003] Therefore, how to reduce the difficulty of repairing or replacing the heating element has become an urgent problem to be solved. Utility Model Content

[0004] This invention aims to at least solve the technical problem of the difficulty in repairing or replacing the lower heating element of an oven in the prior art or related technologies.

[0005] The first aspect of this utility model is to provide an oven.

[0006] This utility model provides an oven, comprising: a cabinet with an opening on its rear side; a rear outer cover installed at the opening for opening or closing the opening; an inner liner disposed within the cabinet; a heat insulation assembly installed between the inner liner and the cabinet; and a heating element disposed within the cabinet and located between the heat insulation assembly and the inner liner. The heat insulation assembly includes a movable cover plate, which can switch between a first state and a second state after the rear outer cover is opened. In the first state, the movable cover plate is disposed between the rear outer cover and the heating element along a first direction. In the second state, the heating element can be inserted from the outside of the cabinet along the first direction between the heat insulation assembly and the inner liner, or the heating element can be pulled out from between the heat insulation assembly and the inner liner along the first direction.

[0007] The oven provided by this utility model includes a cabinet, a rear outer cover, an inner liner, a heat insulation component, and a heating element. The cabinet and rear outer cover constitute the outer shell of the oven, and are the main exterior components of the entire oven. The inner liner is disposed within the oven and contains a cooking cavity for cooking food. The heat insulation component is disposed between the inner liner and the cabinet to insulate and protect the inner liner, improving its heat retention and preventing heat loss. The heating element is installed on the outside of the inner liner to heat it, thereby heating the food inside. Further, the heat insulation component includes a movable cover plate, which is movably installed. When the movable cover plate is in its first state, it is positioned on one side of the heating element and between the heating element and the rear outer cover. The movable cover plate can seal one end of the heating element, reducing the probability of heat loss to the rear outer cover. When installing, repairing, or replacing the heating element, the outer rear cover can be removed first. Then, the movable cover plate can be moved to the second position. Afterward, the heating element can be installed between the outer casing and the inner liner by sliding it in, or pulled out from between the casing and the inner liner by sliding it out. This structure eliminates the need to disassemble the machine to the inner liner or remove the insulation cotton when installing or removing the heating element. Simply open the outer rear cover, switch the movable cover plate to the second position, and gently pry open the insulation cotton at one end of the heating element to expose it for replacement or repair. This structure makes the installation and removal of the heating element very simple, and because it does not require removing the insulation cotton, it requires less technical skill, thus reducing the difficulty and cost of heating element repair and replacement.

[0008] In any of the above embodiments, optionally, the oven further includes: a tube cover, disposed inside the oven body, located between the heat insulation component and the inner liner, with the heating element installed on the side of the tube cover near the inner liner; a first snap-fit ​​component is provided inside the tube cover, and after the heating element is inserted into the tube cover from the outside of the oven body along a first direction, the first snap-fit ​​component can snap onto the tube wall of the heating element.

[0009] In this embodiment, a tube cover is used to support and install the heating element. The tube cover is equipped with a first snap-fit ​​assembly, allowing the heating element to slide into the tube cover from one end along a first direction. After the heating element slides into the tube cover, the first snap-fit ​​assembly engages with the tube wall to limit its movement, preventing the heating element from wobbling within the tube cover and ensuring its stability. Furthermore, this structure, because the portion of the heating element inside the tube cover is not secured with screws during installation, facilitates easier assembly and disassembly, improving operational convenience and making it possible to install or remove the heating element without disassembling the insulation and tube cover.

[0010] In any of the above embodiments, optionally, the first snap-fit ​​assembly includes a first limiting buckle, at least a portion of which is located on the side of the heating tube away from the tube cover, and / or the first snap-fit ​​assembly includes a plurality of second limiting buckles, which are used to limit the heating tube from the width direction of the oven.

[0011] In this embodiment, the first limiting buckle is mainly used to limit the displacement of the heating element in the height direction. For example, the first limiting buckle may include a vertical connecting part and a horizontal limiting part. In the design, the vertical connecting part can be connected to the bottom wall of the tube cover, and the horizontal limiting part is set at a distance from the bottom wall of the tube cover. One end of the horizontal limiting part is connected to the vertical connecting part, and the other end is in a free state (i.e., suspended). In this way, the horizontal connecting part can limit the height of the heating element. Furthermore, the first limiting buckle has an L-shaped structure. Multiple second limiting buckles are used to limit the width of the heating element, thereby preventing the heating element from moving left or right.

[0012] In any of the above embodiments, optionally, one end of the heating element near the rear outer cover is detachably mounted on the tube cover via a threaded connector.

[0013] In this embodiment, to further improve the reliability of the connection between the heating element and the cover, the end of the heating element near the rear outer cover can be installed on the cover using threaded connectors such as screws. When it is necessary to disassemble the heating element, the threaded connector between the rear end of the heating element and the cover can be disassembled first, and then the heating element can be pulled out of the cover. When installing the heating element, it can be inserted into the cover from the end of the cover near the rear outer cover along the first direction, and then the end of the heating element near the rear outer cover and the cover can be connected using threaded connectors such as screws.

[0014] Optionally, the tube cover is provided with screw mounting holes for installing the heating element.

[0015] Of course, in other solutions, the end of the heating element near the rear cover and the cover can also be connected by other structures, such as clips or clamps.

[0016] In any of the above embodiments, optionally, the inner liner includes a bottom plate, an extension extending downward along the height direction of the oven is provided on the end of the bottom plate away from the rear outer cover, the extension and the bottom plate forming a groove, and an insertion part is provided on the end of the tube cover away from the rear outer cover, the insertion part being confined within the groove. The inner liner includes a rear plate, a first fixing buckle is provided on the end of the tube cover near the rear outer cover, and a second fixing buckle is provided on the rear plate, the end of the tube cover near the rear outer cover being fastened to the rear plate by the cooperation of the first fixing buckle and the second fixing buckle. Further, the extension is a bent portion formed by bending the bottom plate downward along the height direction of the oven.

[0017] In this embodiment, the bottom plate can be extended downward to form a bent part, so as to form a slot through the bent part. During installation, the front end of the tube cover can be inserted into the slot first, and then the tube cover can be fastened towards the bottom plate. The end of the tube cover near the rear outer cover is installed on the rear plate through the cooperation of the first fixing buckle and the second fixing buckle. In this way, the tube cover can be quickly installed at the bottom of the inner liner.

[0018] The tube cover has an installation port on one end near the rear outer cover, through which the heating tube can be inserted into the tube cover or pulled out.

[0019] In any of the above embodiments, optionally, the heat insulation component further includes: a first heat insulation support member disposed on the side of the heating tube away from the inner liner, and a movable cover plate rotatably mounted on the first heat insulation support member; and a first heat insulation cotton member installed on the side of the first heat insulation support member close to the heating tube.

[0020] In this embodiment, a first heat-insulating cotton is provided on the inner side (the side near the heating element) of the first heat-insulating support member, which supports and fixes the first heat-insulating cotton. The first heat-insulating cotton can provide heat insulation protection for the heating element and its inner liner, preventing excessive heat dissipation from the inner liner and heating element to the housing. A movable cover plate is installed on one side of the first heat-insulating support member, located at the end of the heating element near the rear outer cover along the first direction. By installing the movable cover plate on the first heat-insulating support member, when disassembling the heating element, it is not necessary to completely remove the movable cover plate; simply rotating and opening the movable cover plate to the desired position is sufficient, thereby reducing the difficulty of maintaining and replacing the heating element.

[0021] In any of the above embodiments, optionally, the heat insulation component further includes: a second heat insulation support member installed between the inner liner and the rear outer cover, the second heat insulation support member having an avoidance notch, in the first state the movable cover plate is sealed in the avoidance notch, and in the second state the movable cover plate opens the avoidance notch; and a second heat insulation cotton installed on the side of the second heat insulation support member near the inner liner.

[0022] In this embodiment, a second heat-insulating cotton is provided on the inner side (the side closest to the inner liner) of the second heat-insulating support member, which supports and fixes the second heat-insulating cotton. The second heat-insulating cotton provides heat insulation protection for the inner liner, preventing excessive heat dissipation from the inner liner to the casing. The second heat-insulating cotton is used to insulate the rear side of the inner liner. To avoid interference between the second heat-insulating support member and the movable cover plate, a clearance notch is provided on the second heat-insulating support member. The movable cover plate is rotatably installed at the clearance notch, allowing the clearance notch to be opened and closed. When the movable cover plate seals the clearance notch, the movable cover plate, the second heat-insulating support member, and the second heat-insulating cotton form a whole, achieving heat insulation of the rear side of the inner liner. After the movable cover is opened to avoid the gap, the second heat insulation cotton at the gap can be deformed and moved to make way for the gap. This allows the end of the heating element near the rear cover to be directly exposed after the rear cover is removed. In this way, the heating element can be repaired and replaced directly on the rear side of the box without removing most of the heat insulation support components and heat insulation cotton.

[0023] In any of the above embodiments, optionally, the first insulation cotton and the second insulation cotton are separate structures.

[0024] In this embodiment, the first heat insulation cotton and the second heat insulation cotton are separate structures, that is, the first heat insulation cotton and the second heat insulation cotton are not a whole. This makes it convenient to install the first heat insulation cotton and the second heat insulation cotton separately. On the other hand, when repairing and replacing the heating tube, the second heat insulation cotton can be squeezed out of the clearance gap more easily to expose the heating tube, thus reducing the difficulty of repairing and replacing the heating tube.

[0025] In any of the above embodiments, optionally, the first insulation cotton and the second insulation cotton are an integral structure. This arrangement can reduce the number of parts.

[0026] In any of the above embodiments, optionally, the rear cover is detachably mounted to the housing by screws.

[0027] In this embodiment, the rear cover is detachably installed on the housing, which facilitates the opening of the rear cover to replace internal parts, such as repairing or replacing the heating element. Furthermore, the rear cover is detachably installed on the housing with screws, making the connection between the rear cover and the housing more reliable and also making the rear cover easier to assemble and disassemble.

[0028] In any of the above embodiments, optionally, the heating element is disposed at the bottom of the inner liner.

[0029] In this embodiment, the heating element is installed at the bottom of the inner cavity, i.e., it is a lower heating element. Of course, the heating element can also be installed in other locations. For example, the heating element can be installed at the top of the inner cavity to facilitate quick disassembly and replacement of the heating element at the top of the oven.

[0030] In any of the above embodiments, optionally, the heating element includes a plurality of interconnected heating segments, which are spaced apart along the width direction of the oven.

[0031] In this embodiment, the heating element is bent to form interconnected heating sections, which ensures the width of the heating element and allows it to be distributed more evenly along the width direction, thereby ensuring the uniformity of heating.

[0032] In any of the above embodiments, the heating element may optionally be a metal heating element. Metal elements have better thermal conductivity, thus ensuring the heating efficiency of the heating element.

[0033] In any of the above embodiments, optionally, the inner liner includes a rear panel, a bottom panel, and a front panel. The rear panel is disposed corresponding to the rear outer cover, the bottom panel forms the bottom of the inner liner, and the heating element is installed below the bottom panel. A first heat insulation support and a first heat insulation cotton are installed below the bottom panel. The front panel is located at the front of the inner liner.

[0034] For an oven, the dimension in the height direction is the height of the oven, the dimension in the left and right direction is the width of the oven, and the dimension in the front and back direction is the thickness of the oven.

[0051] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0052] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0053] like Figures 1 to 12As shown, this utility model provides an oven, including a housing 1, a rear outer cover 2, an inner liner 3, a heat insulation component 4, and a heating element 5. An opening 12 is provided on the rear side of the housing 1. The rear outer cover 2 is installed at the opening 12 and is used to open or close the opening 12. The inner liner 3 is disposed inside the housing 1. The heat insulation component 4 is installed between the inner liner 3 and the housing 1. The heating element 5 is disposed inside the housing 1 and located between the heat insulation component 4 and the inner liner 3. The heat insulation component 4 includes a movable cover plate 42. After the rear outer cover 2 is opened, the movable cover plate 42 can switch between a first state and a second state. When the movable cover plate 42 is in the first state, it is positioned between the rear outer cover 2 and the heating tube 5 along a first direction. When the movable cover plate 42 is in the second state, the heating tube 5 can be inserted from the outside of the housing 1 along a first direction and installed between the heat insulation component 4 and the inner liner 3, or the heating tube 5 can be pulled out of the housing 1 from between the heat insulation component 4 and the inner liner 3 along a first direction.

[0054] The oven provided by this utility model includes a housing 1, a rear outer cover 2, an inner liner 3, a heat insulation component 4, and a heating element 5. The housing 1 and the rear outer cover 2 constitute the outer shell of the oven, and are the main exterior components of the entire oven (see the overall structural diagram of the oven as shown). Figure 11 (As shown). The inner liner 3 is located inside the cabinet 1, and the inner liner 3 has a cooking cavity for cooking food. The heat insulation component 4 is located between the inner liner 3 and the cabinet 1 to provide heat insulation protection for the inner liner 3, improve the heat preservation effect of the inner liner 3, and prevent heat leakage from the inner liner 3. The heating element 5 is installed on the outside of the inner liner 3 to heat the inner liner 3, thereby heating the food inside the inner liner 3. Further, the heat insulation component 4 includes a movable cover plate 42, which is movably installed. When the movable cover plate 42 is in the first state, the movable cover plate 42 is located on one side of the heating element 5, and the movable cover plate 42 is located between the heating element 5 and the rear outer cover 2. The movable cover plate 42 can cover one end of the heating element 5, reducing the probability of heat leakage from the heating element 5 to the rear outer cover 2. When it is necessary to install, repair, or replace the heating element 5, the outer rear cover 2 can be removed first. Then, the movable cover plate 42 can be moved to the second state. After that, the heating element 5 can be installed between the outer side of the housing 1 and the inner liner 3 by sliding insertion, or pulled out from between the housing 1 and the inner liner 3 by sliding extraction. With this structure, it is not necessary to disassemble the machine to the inner liner 3 or remove the heat insulation cotton when installing or removing the heating element 5. After opening the outer rear cover 2, the movable cover plate 42 is switched to the second state. The heat insulation cotton at one end of the heating element 5 is gently pushed aside to make it move, thus exposing the heating element 5. Then, the installation or removal of the heating element 5 can be completed. This structure makes the installation or removal of the heating element 5 very simple. Since it does not require the removal of the heat insulation cotton, the disassembly skills required are low, thereby reducing the difficulty and cost of repairing or replacing the heating element 5.

[0055] In any of the above embodiments, optionally, as Figures 1 to 9 As shown, the oven also includes: a tube cover 6, which is disposed inside the oven body 1 and located between the heat insulation component 4 and the inner liner 3; a heating tube 5 is installed on the side of the tube cover 6 near the inner liner 3; a first snap-fit ​​component 62 is provided inside the tube cover 6; after the heating tube 5 is inserted into the tube cover 6 from the outside of the oven body 1 along the first direction, the first snap-fit ​​component 62 can snap onto the tube wall of the heating tube 5.

[0056] In this embodiment, the tube cover 6 is used to support the installation of the heating element 5. A first snap-fit ​​assembly 62 is provided on the tube cover 6, allowing the heating element 5 to slide into the tube cover 6 from one end along a first direction. After the heating element 5 slides into the tube cover 6, the first snap-fit ​​assembly 62 snaps onto the tube wall of the heating element 5 to limit its movement, thus preventing the heating element 5 from shaking within the tube cover 6 and ensuring its installation stability. Furthermore, this structure, since the portion of the heating element 5 located within the tube cover 6 is not fixed with screws during installation, makes it easier to install and remove the heating element 5, improving its operational convenience and making it possible to install and remove the heating element 5 without disassembling the insulation cotton and the tube cover 6.

[0057] In any of the above embodiments, optionally, as Figure 1 , Figure 3 and Figure 6 As shown, the first snap-fit ​​assembly 62 includes a first limiting buckle 622, at least a portion of which is located on the side of the heating tube 5 away from the tube cover 6, and / or the first snap-fit ​​assembly 62 includes a plurality of second limiting buckles 624, which are used to limit the heating tube 5 from the width direction of the oven.

[0058] In this embodiment, the first limiting buckle 622 is mainly used to limit the displacement of the heating tube 5 in the height direction. For example, the first limiting buckle 622 may include a vertical connecting part and a horizontal limiting part. In the design, the vertical connecting part can be connected to the bottom wall of the tube cover 6, and the horizontal limiting part is spaced a certain distance from the bottom wall of the tube cover 6. One end of the horizontal limiting part is connected to the vertical connecting part, and the other end is in a free state (i.e., suspended). In this way, the horizontal connecting part can limit the height of the heating tube 5. Further, the first limiting buckle 622 has an L-shaped structure. Multiple second limiting buckles 624 are used to limit the width of the heating tube 5, thereby preventing the heating tube 5 from moving left and right.

[0059] In any of the above embodiments, optionally, the end of the heating tube 5 near the rear outer cover 2 is detachably installed on the tube cover 6 via a threaded connector.

[0060] In this embodiment, to further improve the connection reliability between the heating element 5 and the cover 6, the rear end of the heating element 5 (the end closest to the rear outer cover 2) can be installed on the cover 6 using screws or other threaded connectors. When it is necessary to disassemble the heating element 5, the threaded connector between the rear end of the heating element 5 and the cover 6 can be disassembled first, and then the heating element 5 can be pulled out of the cover 6. When installing the heating element 5, it can be inserted into the cover 6 from the rear end along the first direction, and then the rear end of the heating element 5 and the cover 6 can be connected using screws or other threaded connectors.

[0061] In addition, the rear end of the heating element 5 can also be detachably installed on the tube cover 6 via a snap-fit ​​structure; for example, the two can be connected via a quick-release structure.

[0062] Optionally, such as Figure 3 and Figure 6 As shown, the tube cover 6 is provided with screw fixing holes 64 for installing the heating tube 5.

[0063] Of course, in other solutions, the rear end of the heating element 5 and the cover 6 can also be connected by other structures, such as clips or clamps.

[0064] In any of the above embodiments, optionally, as Figure 3 , Figure 5 and Figure 7 As shown, the inner liner 3 includes a base plate 34. An extension 340 extending downwards along the height direction of the oven is provided at one end of the base plate 34 away from the rear outer cover 2. The extension 340 and the base plate 34 form a groove 342. An insertion part 66 is provided at one end of the tube cover 6 away from the rear outer cover 2, and the insertion part 66 is confined within the groove 342. Further, as... Figure 6 , Figure 7 and Figure 12 As shown, the inner liner 3 includes a rear plate 32. A first fixing buckle 68 is provided on one end of the tube cover 6 near the rear outer cover 2, and a second fixing buckle 322 is provided on the rear plate 32. The end of the tube cover 6 near the rear outer cover 2 is fastened to the rear plate 32 by the cooperation of the first fixing buckle 68 and the second fixing buckle 322. Further, the extension 340 is a bent portion formed by bending the bottom plate 34 downward along the height direction of the oven.

[0065] In this embodiment, the base plate 34 can be extended downward to form a bent portion, thereby forming a slot 342. During installation, the front end of the tube cover 6 can be inserted into the slot 342 first, and then the tube cover 6 can be fastened towards the base plate 34. The rear end of the tube cover 6 is then installed on the rear plate 32 through the cooperation of the first fixing buckle 68 and the second fixing buckle 322. This allows for quick installation of the tube cover 6 at the bottom of the inner liner 3. The connection and fixation between the tube cover 6 and the rear plate 32 is achieved through fixing buckles, which reduces the use of screws and makes the installation of the heating element 5 more convenient.

[0066] For example, such as Figure 6 , Figure 7 and Figure 12 As shown, the first fixing buckle 68 is a slot, and the second fixing buckle 322 is a hook. (The last part, "as shown in the diagram," appears to be a fragment and doesn't translate directly.) Figure 7 As shown in the fastening direction, when the tube cover 6 is fastened towards the base plate 34, the hook can be engaged in the slot, thereby achieving a fixed connection between the tube cover 6 and the base plate 34. Of course, the first fixing buckle 68 and the second fixing buckle 322 can also be other compatible fastening structures. For example, one of the first fixing buckle 68 and the second fixing buckle 322 can be a protrusion, and the other can be a groove, or both can be hook-type structures.

[0067] The tube cover 6 has an installation port on one end near the rear outer cover 2, through which the heating tube 5 can be inserted into the tube cover 6 or pulled out.

[0068] In any of the above embodiments, optionally, as Figure 1 , Figure 2 and Figure 4 As shown, the heat insulation component 4 also includes: a first heat insulation support 44, which is disposed on the side of the heating tube 5 away from the inner liner 3, and the movable cover plate 42 is rotatably mounted on the first heat insulation support 44; and a first heat insulation cotton 46, which is installed on the side of the first heat insulation support 44 close to the heating tube 5.

[0069] In this embodiment, a first heat insulation cotton 46 is provided on the inner side of the first heat insulation support 44 (the side closest to the heating element 5), which can support and fix the first heat insulation cotton 46. The first heat insulation cotton 46 can provide heat insulation protection for the heating element 5 and its inner liner 3, preventing excessive heat dissipation from the inner liner 3 and the heating element 5 to the housing 1. The movable cover plate 42 is installed on one side of the first heat insulation support 44 and is located at the end of the heating element 5 near the rear outer cover 2 along the first direction. By installing the movable cover plate 42 on the first heat insulation support 44, when disassembling the heating element 5, it is not necessary to completely remove the movable cover plate 42; it can simply be rotated and opened to the desired position, thereby reducing the difficulty of maintenance and replacement of the heating element 5.

[0070] In any of the above embodiments, optionally, as Figure 1 , Figure 2 and Figure 4As shown, the heat insulation component 4 also includes: a second heat insulation support 48, installed between the inner liner 3 and the rear outer cover 2, the second heat insulation support 48 having an avoidance notch 482, in the first state the movable cover plate 42 blocks the avoidance notch 482, in the second state the movable cover plate 42 opens the avoidance notch 482; and a second heat insulation cotton 49, installed on the side of the second heat insulation support 48 near the inner liner 3.

[0071] In this embodiment, a second heat insulation cotton 49 is provided on the inner side (the side closest to the inner liner 3) of the second heat insulation support 48, which supports and fixes the second heat insulation cotton 49. The second heat insulation cotton 49 provides heat insulation protection for the inner liner 3, preventing excessive heat dissipation from the inner liner 3 to the housing 1. The second heat insulation cotton 49 is used to insulate the rear side of the inner liner 3. To avoid interference between the second heat insulation support 48 and the movable cover plate 42, a clearance notch 482 is provided on the second heat insulation support 48. The movable cover plate 42 is rotatably mounted at the clearance notch 482, allowing the clearance notch 482 to be opened and closed. When the movable cover plate 42 blocks the clearance notch 482, the movable cover plate 42, the second heat insulation support 48, and the second heat insulation cotton 49 form a whole, achieving heat insulation of the rear side of the inner liner 3. After the movable cover plate 42 is opened to avoid the gap 482, the second heat insulation cotton 49 at the gap 482 can be deformed and moved to make way for the gap 482. This allows the rear end of the heating tube 5 to be directly exposed after the rear cover 2 is removed. In this way, the heating tube 5 can be repaired and replaced directly on the rear side of the box 1 without disassembling most of the heat insulation support and heat insulation cotton.

[0072] In any of the above embodiments, the first heat insulation cotton 46 and the second heat insulation cotton 49 are optionally separate structures.

[0073] In this embodiment, the first heat insulation cotton 46 and the second heat insulation cotton 49 are separate structures, that is, the first heat insulation cotton 46 and the second heat insulation cotton 49 are not a whole. This facilitates the separate installation of the first heat insulation cotton 46 and the second heat insulation cotton 49. On the other hand, when repairing and replacing the heating tube 5, the second heat insulation cotton 49 can be more easily squeezed out of the relief notch 482 to expose the heating tube 5, thus reducing the difficulty of repairing and replacing the heating tube 5.

[0074] In any of the above embodiments, optionally, the first insulation cotton 46 and the second insulation cotton 49 are an integral structure. This arrangement can reduce the number of parts.

[0075] In any of the above embodiments, optionally, the rear cover 2 is detachably mounted to the housing 1 by screws.

[0076] In this embodiment, the rear cover 2 is detachably installed on the housing 1, which facilitates the opening of the rear cover 2 to replace the parts inside the housing 1, such as repairing or replacing the heating element 5. Furthermore, the rear cover 2 is detachably installed on the housing 1 by screws, making the connection between the rear cover 2 and the housing 1 more reliable, and also making the rear cover 2 easier to assemble and disassemble.

[0077] In any of the above embodiments, optionally, as Figure 10 As shown, the heating element 5 is located at the bottom of the inner liner 3.

[0078] In this embodiment, the heating element 5 is installed at the bottom (i.e., the lower part) of the entire inner cavity 3, that is, the heating element 5 is the lower heating element. Of course, the heating element 5 can also be installed in other positions. For example, the heating element 5 can be installed at the top of the inner cavity 3 to facilitate quick disassembly and replacement of the heating element 5 at the top of the oven.

[0079] Furthermore, the oven can be a heating element oven, a microwave-steam oven, or a combination oven that integrates microwave heating and air heating.

[0080] In any of the above embodiments, optionally, as Figure 4 and Figure 9 As shown, the heating element 5 includes multiple interconnected heating sections 52, which are spaced apart along the width of the oven.

[0081] In this embodiment, the heating tube 5 is bent to form interconnected heating sections 52, thereby ensuring the width of the heating tube 5 and making the heating tube 5 more evenly distributed along the width direction, thus ensuring the uniformity of heating of the heating tube 5.

[0082] In any of the above embodiments, the heating element 5 may optionally be a metal heating element. Metal elements have better thermal conductivity, which can ensure the heating efficiency of the heating element 5.

[0083] In any of the above embodiments, optionally, as Figures 1 to 9 As shown, the inner liner 3 includes a rear panel 32, a bottom panel 34, and a front panel 36. The rear panel 32 is positioned corresponding to the rear outer cover 2, and the bottom panel 34 forms the bottom of the inner liner 3. The heating element 5 is installed below the bottom panel 34. The first heat insulation support 44 and the first heat insulation cotton 46 are installed below the bottom panel 34. The front panel 36 is located at the front of the inner liner 3.

[0084] For an oven, the dimension in the height direction is the height of the oven, the dimension in the left and right direction is the width of the oven, and the dimension in the front and back direction is the thickness of the oven.

[0085] in, Figure 3 and Figure 6The arrow in the image indicates the insertion direction when the heating element is inserted into the cover.

[0086] In electric ovens, Bake and Convection Bake are common menu options, both requiring a lower heating element. In the manufacturing process, the lower heating element is typically secured to the heating element cover with screws, and then the cover assembly is screwed to the oven cavity to ensure reliable installation. However, this design requires disassembling the machine to remove the heating element and cover for repairs. Only after disassembling down to the cavity assembly (inner chamber) can the lower heating element cover assembly be removed to replace the heating element. Removing the cavity insulation can potentially affect the overall performance of the oven, making lower heating element replacement difficult and potentially impacting machine performance.

[0087] It is evident that the proposed solution involves replacing the lower heating element, which presents challenges in after-sales maintenance, low efficiency, requires complete disassembly down to the cavity components, and the removal of the cavity insulation may affect the machine's performance.

[0088] Figure 1 This is a cross-sectional view of the lower heating element for maintenance, mainly including the cavity base plate, front plate, cavity insulation cotton, cavity rear plate, cavity rear insulation cotton, rear insulation cotton support plate, rear outer cover, lower metal heating element, lower insulation cotton support plate, and lower heating element cover. The lower heating element is installed in the lower heating element cover. The lower heating element cover assembly is located vertically between the cavity base plate and the cavity insulation cotton, and frontally between the front plate and the cavity rear insulation cotton. The rear insulation cotton is sealed behind the cavity rear insulation cotton by the lower insulation cotton support plate, and the outermost part is the rear outer cover.

[0089] Figure 2 and Figure 3 This diagram illustrates the process of repairing the lower heating element after removing the rear cover. To repair the lower heating element, first remove the rear cover. Then, loosen the two screws on the lower insulation support plate and pry it open to 90° along the row of oblong holes. Next, pry open the rear insulation of the cavity and loosen one of the heating element fixing screws. Finally, pull the lower heating element out of the lower heating element cover to complete the removal. To replace the lower heating element, first insert it into the lower heating element cover. During insertion, press down on the lower heating element using the lower heating element cover's clips to secure it. Then, tighten the screws to secure the lower heating element. Next, pry the rear insulation of the cavity and the lower insulation support plate back from their open positions and tighten them with screws. Finally, secure the rear cover to complete the replacement of the lower heating element.

[0090] Figure 4 This is an exploded view of the parts for repairing the lower heating element, showing the detailed structure of each component.

[0091] This utility model, through its structural design, eliminates the need to first remove the electric oven from the cabinet, then disassemble the oven's rear cover, loosen the two screws behind the lower insulation cotton support plate, and pry the rear part open by 90 degrees to replace the lower heating element. This solves the problem of complete disassembly for after-sales repair, which affects the overall performance of the machine, and improves after-sales repair efficiency. Furthermore, the integrated design of the heating element rear cover and the lower insulation cotton support plate reduces the number of parts, thereby reducing production and installation procedures and labor costs.

[0092] in, Figure 5 This is a cross-sectional view after the lower heating element is installed, mainly including the cavity base plate, cavity rear plate, lower heating element, and lower heating element cover. The lower heating element is installed inside the heating element cover, and the entire heating element cover assembly is located below the cavity base plate and fastened to the cavity rear plate.

[0093] Figure 6 This is a schematic diagram for installing the lower heating element. First, place the lower heating element inside the heating element cover, ensuring the heating element rod is positioned behind the cover's locking mechanism. Then, slide the lower heating element into the cover's locking mechanism, securing the heating element rod. Next, fix the heating element in place with screws at the screw holes in the cover. This completes the installation of the lower heating element.

[0094] Figure 7 and Figure 8 This is a schematic diagram of the installation of the lower heating element cover assembly. First, insert the locking part of the lower heating element cover into the bent part of the cavity base plate (i.e., the locking groove 342), and then snap the entire lower heating element cover assembly toward the cavity base plate (the snapping direction is as shown). Figure 7 As shown in the diagram, the lower heating element cover is simultaneously snapped into the rear plate of the cavity, thus ensuring that the vertical and horizontal displacement of the lower heating element cover is fixed. The horizontal displacement of the lower heating element cover is limited by the limiting device on the rear plate of the cavity, thereby completing the installation and fixing of the lower heating element cover.

[0095] like Figure 9 The exploded view of the components for mounting the lower heating element shows the detailed structure of each part.

[0096] Key improvements: quick replacement of the lower heating element; integrated structure of the lower heating element rear cover and lower insulation cotton support plate; maintenance of the lower heating element without disassembling the cavity insulation cotton; maintenance of the lower heating element only requiring removal of the rear outer cover. When installing the metal heating element, it is secured using clips and a single screw, and then the metal heating cover assembly is quickly fixed to the oven cavity via insertion and clipping. This design effectively solves the problem of complex installation, simplifies the production process, shortens labor time, and greatly improves production efficiency.
