[0022] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-4 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0023] Please refer to Figures 1 to 4 , the present application provides a bellows device, which comprises:

[0024] The bellows 1 includes a cavity 11, and a side wall of the bellows 1 is provided with an exhaust port 12 communicating with the outside and the cavity; the cavity 11 is used to install electrical components, such as a fan, etc. The exhaust port 12 is used to exhaust the oil smoke exhausted from the fan to the outside.

[0025] The fan 2 includes at least one air outlet 21, at least one air outlet 21 is arranged toward the exhaust port 12, and the fan 2 is installed in the cavity 11. The fan 2 can be fixedly installed in the cavity 11 by a support and / or screws. The fan is used to absorb the oil smoke generated by the integrated stove and discharge the oil smoke to the outside through the air outlet 21.

[0026] The air outlet cover 3 is provided with a mounting plate 31, which is in contact with the inner wall of the bellows 1, and at least part of the mounting plate 31 covers the air outlet 12. The mounting plate 31 is in contact with the side of the bellows 1 and an air outlet portion 32 extends outward. In this way, the mounting plate 31 of the air outlet cover 3 is in a negative pressure environment, and the negative pressure can reduce the sealing requirements between the air outlet cover 3 and the inner wall of the cavity 11, and no sealing ring is required, and air leakage and oil leakage can be prevented.

[0027] The air outlet hood 3 is provided with an air outlet passage 33 penetrating the air outlet hood 3 , and the air outlet 21 is connected to the air outlet passage 33 . Thus, the oil smoke coming out of the air outlet 21 can be discharged along the air outlet passage 33 of the air outlet hood 3 .

[0028] The inner wall of the bellows 1 is provided with a mounting groove 13, and the mounting groove 13 is located above the air outlet 12, and the mounting plate 31 is fixedly connected to the mounting groove 13. In this way, the position of the air outlet cover 3 is relatively stable, and the problem of air leakage and oil leakage caused by the unstable installation of the air outlet cover 3 can be reduced.

[0029] One end of the mounting plate 31 is connected to the mounting groove 13 by a fastener. The fastener can be a screw. Of course, one end of the mounting plate 31 and the mounting groove 13 can also be fixedly connected by welding, bonding, etc.

[0030] The inner wall of the bellows 1 is provided with an abutment portion 14, and the abutment portion 14 is located below the air outlet 12, and the mounting plate 31 abuts against the abutment portion 14. This can further reduce the risk of air leakage of the bellows 1.

[0031] A limiting portion 34 is provided at the lower side of the air outlet cover 3, and the abutting portion 14 is provided between the limiting portion 34 and the other end of the mounting plate 31, and a gap is provided between the limiting portion 34 and the abutting portion 14. This facilitates the installation of the air outlet cover 3 and prevents the installation of the air outlet cover 3 from being affected by manufacturing errors or installation errors of the air outlet cover 3 or the bellows 1.

[0032] A mounting opening 35 is extended inwardly on one side of the mounting plate 31 abutting against the bellows 1, and a mounting opening 36 is provided on the mounting opening 35, which is a part of the air outlet passage 33. The mounting opening 35 extends from the air outlet 12 into the cavity 11, which can further reduce air leakage between the mounting opening 35 and the air outlet 21.

[0033] The fan 2 is provided with at least one air outlet portion 22 for opening the air outlet 21, and the air outlet portion 22 extends from the mounting opening 36 into the mounting opening portion 35, and the outer wall of the air outlet portion 22 and the inner wall of the mounting opening portion 35 are clearance-matched. This facilitates the installation of the air outlet portion 22 of the fan 2 into the mounting opening portion 35. A sealing ring may also be added between the outer wall of the air outlet portion 22 and the inner wall of the mounting opening portion 35 to increase the static pressure of the pipeline.

[0034] The present application also provides an integrated stove, which includes the above-mentioned bellows device.

[0035] The above are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Any feature disclosed in this specification (including the abstract and drawings), unless otherwise stated, can be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.
