Description

Technical Field

[0001] This utility model relates to the technical field of ovens, and in particular to an oven that is easy to clean. Background Technology

[0002] An electric oven is a kitchen appliance that uses electrical energy to convert into heat energy for cooking and baking food. Electric ovens mainly generate heat by turning on the heating element, and then use a fan (some ovens have this feature) to evenly distribute the heat inside the oven, so that the food can be heated, baked, or roasted in a set temperature environment. After using the electric oven, it is necessary to clean the residue and grease inside the oven in time to keep the oven clean and hygienic and extend its service life. Therefore, an oven that is easy to clean is needed.

[0003] Existing ovens that are easy to clean are not easy to clean directly when the interior gets greasy because the inner cavity and the outer shell are tightly installed. Too much grease inside can affect the oven's performance.

[0004] To address the aforementioned issues, a search revealed a patent with publication number CN218738448U that discloses an oven designed for easy internal cleaning. The patent proposes "an oven liner and a grid rack within the oven liner, along with a snap-fit ​​mechanism on the oven liner, allowing for easy installation of the oven liner inside the oven body. This replaces the traditional internal support structure, enabling quick installation and removal of the oven liner. The oven liner also collects food residue, ensuring it is concentrated within the liner for easy cleaning. Furthermore, the grid rack, with its adjustable grooves, allows for adjusting the spacing between the grid racks according to food height, enhancing the oven's practicality." While the connecting clips and return springs can engage in the connecting slots, there is no way to press the clips during disassembly. The liner must be pulled forcefully to deform the return spring, which not only causes jamming during disassembly but also easily damages the return spring.

[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content

[0006] The purpose of this invention is to provide an easy-to-clean oven to solve the problem mentioned in the background art that existing easy-to-clean ovens, due to the tight installation of the inner liner and the outer shell, are not easy to clean directly when oil stains are inside, and excessive oil stains inside will affect the oven's performance.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an oven that is easy to clean, comprising an oven shell, a positioning rod fixedly installed on the bottom surface of the inner wall of the oven shell, a spring sleeved on the inner end of the positioning rod, a limiting ring fixedly installed on the outer ring of the spring, an inner liner slidably placed on one end of the oven shell, a positioning hole opened at one end of the inner liner corresponding to the positioning rod, support plates fixedly installed on both sides of the inner wall of the inner liner, a connecting plate slidably connected to one side of the support plate, a grid plate fixedly installed on one side of the connecting plate, ventilation holes opened on both sides of the upper surface of the inner liner, guide plates fixedly installed on both sides of the upper surface of the inner liner corresponding to the ventilation holes, heating tubes installed in the internal partitions on the upper and lower sides of the oven shell, a filter screen installed at the opening on the upper surface of the oven shell, and a fan shell fixedly installed on the upper surface of the oven shell.

[0008] Preferably, the positioning rods are provided in four sets, each corresponding to a positioning hole. The positioning hole is divided into two sections: the front section matches the size of the positioning rod, and the rear section matches the size of the limiting ring.

[0009] Preferably, both the support plate and the connecting plate are triangular structures, and the support plates are evenly distributed on the inner side of the inner liner.

[0010] Preferably, limit blocks are fixedly installed on both sides of the lower part of the inner wall of the inner liner, and an oil collection box is slidably connected to one end of the limit block.

[0012] Preferably, fixing blocks are fixedly installed on the upper and lower sides of the front surface of the oven shell, and connecting blocks are sleeved on the outer ring of the fixing blocks, with a pressing block fixedly installed at one end of the connecting blocks.

[0013] Preferably, the extrusion block is rotated and attached to the upper and lower sides of the inner liner via the connecting block, and a damping rubber ring is provided on the contact surface between the connecting block and the fixing block.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This easy-to-clean oven, through the cooperation of the positioning rod, spring and limiting ring, allows the inner liner to be easily slidably installed or removed, avoiding the jamming problem caused by spring deformation in traditional snap-fit ​​structures, thus improving cleaning efficiency. The support plate and connecting plate adopt a triangular structure, which can flexibly adjust the position of the grid plate to adapt to different food sizes. At the same time, the evenly distributed distribution ensures uniform heating. The limiting block cooperates with the oil collection box, allowing oil stains generated during cooking to flow directly into the oil collection box, avoiding the spread of oil stains and reducing cleaning difficulty. The fixing block, connecting block and squeezing block, together with the damping rubber ring, ensure that the inner liner is installed firmly and prevents shaking, while also facilitating quick disassembly and assembly.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5This utility model provides a technical solution: an oven that is easy to clean, including an oven shell 1, a positioning rod 2 fixedly installed on the bottom surface of the inner wall of the oven shell 1, a spring 3 sleeved on the inner end of the positioning rod 2, a limiting ring 4 fixedly installed on the outer ring of the spring 3, an inner liner 5 slidably placed on one end of the oven shell 1, a positioning hole 6 opened at one end of the inner liner 5 corresponding to the positioning rod 2, support plates 7 fixedly installed on both sides of the inner wall of the inner liner 5, a connecting plate 8 slidably connected to one side of the support plate 7, a grid plate 9 fixedly installed on one side of the connecting plate 8, ventilation holes 12 opened on both sides of the upper surface of the inner liner 5, guide plates 13 fixedly installed on both sides of the upper surface of the inner liner 5 corresponding to the ventilation holes 12, heating tubes 14 installed in the internal partitions on the upper and lower sides of the oven shell 1, a filter screen 15 installed at the opening on the upper surface of the oven shell 1, and a fan shell 16 fixedly installed on the upper surface of the oven shell 1.

[0023] Furthermore, four sets of positioning rods 2 are provided, each corresponding to a positioning hole 6. The positioning hole 6 is divided into two sections: the front section matches the size of the positioning rod 2, and the rear section matches the size of the limiting ring 4. Through the arrangement of the positioning rods 2 and the positioning holes 6, the four sets of positioning rods 2 provide uniform support, ensuring that the inner liner 5 is installed stably. The front section of the positioning hole 6 matches the positioning rod 2 to achieve initial positioning, and the rear section matches the limiting ring 4, providing slight elasticity under the action of the spring 3, allowing the inner liner 5 to be easily slidably installed or removed without jamming.

[0024] Furthermore, both the support plate 7 and the connecting plate 8 are triangular structures. The support plates 7 are evenly distributed on the inner side of the inner liner 5. Through the setting of the support plates 7, the triangular structure of the support plates 7 can provide stable support and facilitate the flow of oil stains from top to bottom.

[0025] Furthermore, limit blocks 10 are fixedly installed on both sides of the inner wall of the inner cavity 5 at the lower position. One end of the limit block 10 is slidably connected to an oil collection box 11. With the setting of the oil collection box 11, oil stains flow into the oil collection box 11 along the wall of the inner cavity 5, avoiding contamination of the oven interior and reducing the cleaning frequency.

[0026] Furthermore, an intake fan is installed inside the fan housing 16, and the ventilation hole 12 is connected to the oven housing 1 and the fan housing 16. Through the setting of the fan housing 16, the intake fan installed inside the fan housing 16 can continue to blow air using the internal preheating after baking is completed and the baked items are taken out. While accelerating heat dissipation, the hot air driven corresponds to both sides of the inner liner 5, which can also accelerate the downward flow of oil stains into the oil collection box 11.

[0027] Furthermore, fixing blocks 17 are fixedly installed on the upper and lower sides of the front surface of the oven shell 1. A connecting block 18 is sleeved on the outer ring of the fixing block 17. A pressing block 19 is fixedly installed on one end of the connecting block 18. Through the setting of the pressing block 19, the fixing block 17 provides a support point, the connecting block 18 can be rotated to adjust the angle, and the pressing block 19 fits against the inner liner 5 to provide stable pressure, prevent the inner liner 5 from shaking, and facilitate quick disassembly and assembly.

[0028] Furthermore, the extrusion block 19 is rotated and attached to the upper and lower sides of the inner liner 5 via the connecting block 18. The contact surface between the connecting block 18 and the fixing block 17 is provided with a damping rubber ring. Through the setting of the connecting block 18, the inner ring of the connecting block 18 is provided with a damping rubber ring and is attached to the fixing block 17, which can facilitate the fixing position after rotation.

[0029] Working principle: First, align the inner liner 5 with the positioning rod 2 on the outer shell 1 of the oven and gently push it in. The front part of the positioning rod 2 is inserted into the front half of the positioning hole 6. At the same time, the position of the positioning hole 6 on the rear half of the inner liner 5 is in contact with the limiting ring 4. Continue to push the inner liner 5 to compress the spring 3. Next, rotate the connecting block 18 on the fixing block 17 to make the pressing block 19 fit against the upper and lower sides of the inner liner 5. The damping rubber ring, together with the rebound force of the spring 3, provides stable pressure to prevent the inner liner 5 from shaking. Then, place the items to be heated on the grid plate 9, and connect them through the connecting plate 8 and the support plate 7. Slide the inner liner 14 into the oven cavity 5, then turn on the heating element 14 to heat it up for baking. During the process, the splashed oil stains flow along the inner wall of the inner liner 5 into the oil collection box 11. When cleaning is needed, rotate the connecting block 18, and the squeezing block 19 will disengage from the inner liner 5 to release the fixation. Then the spring 3 will rebound and push the inner liner 5 outward a part. Gently pull the inner liner 5 to make it slide out easily. Take out the oil collection box 11 and clean off the oil stains. At the same time, the inner liner 5 can also be cleaned quickly. Finally, push the inner liner 5 back into the oven shell 1 to complete the installation and prepare for the next use.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
