Description

Technical Field

[0001] This utility model relates to the field of electric oven technology, and specifically to an improved electric oven. Background Technology

[0002] As consumers increasingly demand convenience from electric ovens, their need for ease of cleaning is also growing. However, because the heating elements of traditional electric ovens are fixed, grease and other residues drip into the heating chamber after use, making cleaning the heating chamber difficult and inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide an electric oven with an easy-to-clean heating chamber.

[0004] The purpose of this utility model is achieved as follows.

[0005] An improved electric oven includes a heating cavity and an electric heating element. The electric heating element has insertion parts at both ends and limiting parts near the ends of both ends. The heating cavity has mounting holes on opposite sides. The insertion parts are inserted into the mounting holes and can rotate relative to the mounting holes, causing the middle part of the electric heating element to rotate. The middle part of the electric heating element is bent and has a support part. When the bottom of the support part abuts against the heating cavity, the middle part and both ends of the electric heating element are on the same horizontal plane. The heating cavity has a waterproof device at the mounting hole. The end of the electric heating element passes through the waterproof device, and the limiting part is axially limited within the waterproof device.

[0006] Furthermore, the waterproof device includes a waterproof sleeve and a waterproof cover. One end of the waterproof sleeve is fixed to the heating cavity. The inner cavity of the waterproof sleeve is connected to the mounting hole. The waterproof cover is connected and fixed to the heating cavity. The waterproof cover covers the waterproof sleeve. The waterproof cover has a shaft hole. The insertion part passes through the shaft hole, the waterproof sleeve is inserted into the mounting hole, and the limiting part is placed between the waterproof sleeve and the waterproof cover.

[0007] The waterproof device and the limiting part work together to restrict the axial movement of the electric heating tube, while the shaft hole restricts the radial movement of the electric heating tube, allowing the electric heating tube to rotate radially.

[0008] Furthermore, one end of the waterproof sleeve is embedded in the mounting hole, and the other end of the waterproof sleeve faces into the heating cavity and gradually expands in diameter to form a flared mouth. The limiting part is annular and is placed inside the flared mouth. The bottom of the limiting part abuts or is close to the flared mouth.

[0009] The waterproof sleeve design prevents water from easily entering the mounting hole from the outside. Water entering through the shaft hole along the heating element is blocked by the limiting part and falls out through the flared opening. The waterproof cover prevents water from directly entering the mounting hole from the flared opening. Overall, the waterproof effect is excellent, and the heating chamber is easy to clean.

[0010] Furthermore, the waterproof cover and the heating chamber are fastened together by connectors, and drainage gaps are provided at the bottom of the waterproof cover and the heating chamber. Water can be easily drained from the waterproof cover.

[0011] Furthermore, the heating cavity has protrusions on its two opposite sides near the same end, and the protrusions have the mounting holes. The heating cavity also has a drain hole at its lowest point.

[0012] The heating element rotates easily, the heating chamber drains easily, and it is easy to clean.

[0013] This utility model's waterproof device and limiting part work together to restrict the axial and radial movement of the electric heating element, allowing the heating element to rotate easily and thus facilitating cleaning of the heating chamber. The waterproof device prevents water from entering the installation chamber, making it safer to use. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example 1, see Figures 1-6 As shown, an improved electric oven includes a heating cavity 1, an electric heating element 2, and a waterproof device 3.

[0022] A concave cavity 10 is formed inside the heating cavity 1. Mounting holes 11 are provided on two opposite sides of the concave cavity 10, and a drain hole 13 is provided at the lowest position of the bottom of the concave cavity 10. In this embodiment, protrusions 12 are provided on the left and right sides of the concave cavity 10 near the rear end, and the mounting holes 11 are provided on the protrusions 12.

[0023] There is only one electric heating element 2. The electric heating element 2 has an insertion part 21 at both ends and a limiting part 22 near the end of each end. The electric heating element 2 is bent in the middle and has a supporting part 23. The limiting part 22 is circular.

[0024] The waterproof device 3 includes a waterproof sleeve 4 and a waterproof cover 5. One end of the waterproof sleeve 4 is fixed to the heating cavity 1, and the inner cavity of the waterproof sleeve 4 is connected to the mounting hole 11. The waterproof cover 5 is connected and fixed to the heating cavity 1, and covers the waterproof sleeve 4. The waterproof cover 5 is provided with a shaft hole 51. One end of the waterproof sleeve 4 is sealed and embedded in the mounting hole 11, and the other end of the waterproof sleeve 4 faces the heating cavity 1 and gradually increases in diameter to form a flared mouth 40.

[0025] After the insertion part 21 of the electric heating element 2 passes through the shaft hole 51 of the waterproof cover 5, the limiting part 22 is then fixed to the electric heating element 2. The diameter of the limiting part 22 is larger than the diameter of the shaft hole 51, and the diameter of the limiting part 22 is smaller than the maximum diameter of the flared mouth 40 but larger than the minimum diameter of the flared mouth 40. After the insertion part 21 of the electric heating element 2 extends from the flared mouth 40 through the waterproof sleeve 4 and the mounting hole 11 to the outside of the heating cavity 1, the insertion part 21 of the electric heating element 2 is connected to the wire for conduction. The waterproof cover 5 is fastened by a connector (such as a screw) and the protrusion 12. The bottom of the waterproof cover 5 and the protrusion 12 are provided with a drainage gap 50. The drainage gap 50 can be formed by the installation gap between the waterproof cover 5 and the protrusion 12, or it can be formed by a pre-reserved installation gap.

[0026] The end of the electric heating element 2 passes through the waterproof device 3, and the limiting part 22 is axially limited within the waterproof device 3. Specifically, the limiting part 22 is placed between the waterproof sleeve 4 and the waterproof cover 5, and the limiting part 22 is placed within the flared opening 40, with its bottom abutting or close to the flared opening 40. The waterproof sleeve 4 and the waterproof cover 5 together restrict the degree of freedom of the limiting part 22 in axial and radial translation, while the electric heating element 2 can rotate relative to the mounting hole 11 and the shaft hole 51, and the middle part of the electric heating element 2 can perform a flipping motion.

[0027] During normal use, the bottom of the support 23 abuts against the heating cavity 1, and the middle and both ends of the electric heating tube 2 are on the same horizontal plane. During cleaning, the electric heating tube 2 rotates as a whole, meaning the middle of the electric heating tube 2 flips upwards, making it easier to clean the heating cavity 1. During cleaning, most of the water is blocked by the waterproof cover 5, meaning most of the water flows away along the surface of the waterproof cover 5. A small amount of water enters the waterproof cover 5 through the gap between the top of the waterproof cover 5 and the protrusion 12. This portion of water is blocked by the waterproof sleeve 4 and cannot enter the mounting hole 11. A small amount of water also enters the waterproof cover 5 along the electric heating tube 2 through the shaft hole 51. This portion of water is blocked by the limiting part 22 and guided downwards through the flared opening 40, also preventing it from entering the mounting hole 11. The water inside the waterproof cover 5 flows downwards through the drain gap 50. This prevents water from entering the oven through the mounting hole 11, avoiding problems such as short circuits caused by water ingress, making it safer to use after cleaning. The arrows in the diagram illustrate the water flow.
