[0031] See Figures 1 - 4 , this utility model provides a drain pipe fixing structure for a steam oven, which includes a fixed connecting pipe 2. One end of the fixed connecting pipe 2 is used for inserting into the drain pipe of the steam oven. An annular boss 21 extending outward is provided on the side wall of the fixed connecting pipe 2. At least one elastic sheet structure 22 is provided on the outer side wall of the fixed connecting pipe 2. A clamping position is formed between the elastic sheet structure 22 and the annular boss 21, and the clamping position is used for clamping the front plate of the steam oven. The other end of the fixed connecting pipe 2 is used for draining the water in the drain pipe into the waste water box of the steam oven. By inserting the fixed connecting pipe 2 into the front plate of the steam oven, the fixed connecting pipe 2 is fixedly connected to the steam oven, and then the drain pipe is inserted into the fixed connecting pipe 2 to fix the drain pipe, without using parts such as bolts for fixing. When the fixed connecting pipe 2 is inserted into the front plate, the elastic sheet structure 22 is elastically compressed inward. When the fixed connecting pipe 2 is installed in place, the elastic sheet structure 22 rebounds, so that the front plate is clamped in the clamping position to realize the fixation of the fixed connecting pipe 2.

[0032] Specifically, the fixed connecting pipe 2 is divided into a front end part and a rear end part. The front end part is inserted into the front plate of the steam oven, and the rear end part is connected to the drain pipe. A guiding side wall is provided on the side wall of the rear end part, and the guiding side wall gradually decreases from front to back. When the drain pipe is sleeved on the rear end part, it can be gradually inserted and tightened along the guiding side wall, and finally an interference connection is realized, so that the connection part between the drain pipe and the fixed connecting pipe 2 is sealed, and water will not leak from the connection part between the drain pipe and the fixed connecting pipe 2.

[0033] Furthermore, the elastic sheet structure 22 includes a first elastic sheet 221 and a second elastic sheet 222. The first elastic sheet 221 is connected to the outer side wall of the fixed connecting pipe 2. One end of the first elastic sheet 221 is connected to the outer side wall of the fixed connecting pipe 2, and the other end of the first elastic sheet 221 gradually inclines outward toward the annular boss 21 and is connected to the first elastic sheet 221. The second elastic sheet 222 is arranged along the radial direction of the fixed connecting pipe 2, and the clamping position is formed between the second elastic sheet 222 and the annular boss 21. When the fixed connecting pipe 2 is inserted into the front plate of the steam oven, the first elastic sheet 221 drives the second elastic sheet 222 to be elastically compressed inward together. When the fixed connecting pipe 2 is installed in place, the first elastic sheet 221 drives the second elastic sheet 222 to rebound, so that the front plate is clamped in the clamping position to realize the fixation of the fixed connecting pipe 2.

[0034] Furthermore, a drainage structure 24 extending downward is provided on the end wall of the fixed connection pipe 2, and the end of the drainage structure 24 is arranged vertically downward. When the amount of water passing through the fixed connection pipe 2 is large, it will spray out due to gravity. When the water flow rate passing through the fixed connection pipe 2 is small, it will flow back along the water outlet port of the fixed connection pipe 2 due to the surface tension of water. The present utility model provides a drainage structure 24 on the end wall of the water outlet end of the fixed connection pipe 2 to drain water and prevent water from flowing back due to the surface tension of water at the water outlet port.

[0035] Furthermore, the drainage structure 24 includes a drainage guiding block 241 and drainage bumps 242. The drainage guiding block 241 is arranged on the end wall of the fixed connection pipe 2, and the drainage guiding block 241 is located below the fixed connection pipe 2. The connections between the front wall and the top wall, and between the front wall and the bottom wall of the drainage guiding block 241 are both arc-shaped structures. The drainage bumps 242 are arranged at the connection between the bottom wall and the rear wall of the drainage guiding block 241. When the water flow rate passing through the fixed connection pipe 2 is small, water will flow along the drainage guiding block 241 to the drainage bumps 242, accumulate into water droplets at the drainage bumps 242, and finally drop under the action of gravity, achieving the anti-backflow effect and preventing water from flowing back due to the surface tension of water at the water outlet port.

[0036] Furthermore, two elastic sheet structures 22 are provided on the outer side wall of the fixed connection pipe 2, and the two elastic sheet structures 22 are distributed on the left and right sides of the fixed connection pipe 2, making the fixation of the fixed connection pipe 2 more firm.

[0037] Furthermore, a limiting rib 23 arranged axially is provided on the side wall of the fixed connection pipe 2. The limiting rib 23 is used to limit the installation position of the fixed connection pipe 2 to ensure that the drainage structure 24 is always located directly below the fixed connection pipe 2, so as to ensure that the drainage structure 24 can function and avoid backflow.

[0038] See Figures 5 - 7 , the present utility model also provides a steam oven, including a front plate 1 and the drain pipe fixing structure as described above. An installation hole 11 is provided on the front plate 1, the fixed connection pipe 2 is inserted into the installation hole 11, and the hole wall of the installation hole 11 is clamped at the clamping position. The drain pipe fixing structure includes a fixed connection pipe 2. One end of the fixed connection pipe 2 is used for inserting into the front plate of the steam oven, the other end of the fixed connection pipe 2 is used for inserting into the drain pipe of the steam oven. An annular boss 21 extending outward is provided on the side wall of the fixed connection pipe 2. At least one elastic sheet structure 22 is provided on the outer side wall of the fixed connection pipe 2. A clamping position is formed between the elastic sheet structure 22 and the annular boss 21, and the clamping position is used for clamping the front plate of the steam oven.

[0039] Specifically, the elastic sheet structure 22 and the annular boss 21 are both arranged on the side wall of the front end of the fixed connection pipe 2. The installation hole 11 is a flanging hole, the elastic sheet structure 22 abuts against the rear end wall of the flanging hole, and the annular boss 21 abuts against the front side wall of the flanging hole. When the fixed connection pipe 2 is inserted into the installation hole 11, the elastic sheet structure 22 is elastically compressed inward. After the fixed connection pipe 2 is installed in place, the elastic sheet structure 22 rebounds and abuts against the rear end wall of the installation hole 11 to realize the fixation of the fixed connection pipe 2.

[0040] Further, a limiting groove 111 is provided on the top wall of the installation hole 11. The limiting groove 111 is used for the limiting rib of the fixed connection pipe 2 to be inserted to limit the installation position of the fixed connection pipe 2, so that the drainage structure 24 can always be located directly below the fixed connection pipe 2, ensuring that the drainage structure 24 can function.

[0041] Further, the steam oven includes a cavity 4 and a drainage conduit 3. The front plate 1 is arranged on the front side wall of the cavity 4. A drainage port is provided on the cavity 4. One end of the drainage conduit 3 is connected to the drainage port, and the other end is inserted into the fixed connection pipe 2. The waste water and condensed water of the steam oven are guided to the fixed connection pipe 2 through the drainage conduit 3 and flow out through the internal channel in the fixed connection pipe 2. The drainage structure 24 on the fixed connection pipe 2 can guide the water flow to avoid backflow.

[0042] Further, the steam oven further includes a waste water box 5. The waste water box 5 is arranged at the bottom of the front plate 1. A water receiving groove 51 is opened on the top wall of the waste water box 5. The water receiving groove 51 is located below the fixed connection pipe 2. The waste water and condensed water of the steam oven are guided to the fixed connection pipe 2 through the drainage conduit 3 and flow out through the internal channel in the fixed connection pipe 2, and finally flow to the waste water box 5 to recover the waste water and condensed water of the steam oven.

[0043] Specifically, the waste water box 5 is a detachable structure. When the water receiving groove 51 is full of water, the waste water box 5 can be detached, the water in the water receiving groove 51 can be poured out, and the waste water box 5 can be installed again.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the protection scope of the invention.
