As shown in fig. 14 and fig. 4 and 8, the tank 2 is further provided with an oil collecting port 26, the oil collecting port 26 is located below the smoke outlet 23, an oil collecting channel 4020 is arranged at the bottom of the fixing seat 402, and two ends of the oil collecting channel 4020 are respectively communicated with the oil collecting port 26 and the exhaust pipe assembly 403. When the fan 1 is started, a negative pressure environment is formed in the box body 2, and a negative pressure environment is also formed in the oil collecting channel 4020 communicated with the box body 2, when oil leakage occurs in the exhaust pipe assembly 403, under the action of negative pressure, leaked oil dirt can be sucked back into the box body 2 again, and leakage from the joint of the exhaust pipe assembly 403 and the fixing seat 402 is avoided. Optionally, a pull-out oil sump may be provided in the housing 2 to collect the oil dirt sucked back from the oil collection channel 4020, and the user may clean the oil dirt periodically to maintain the cleanliness of the integrated kitchen range.

The above embodiments merely illustrate the basic principle and features of the present invention, and the present invention is not limited to the above embodiments, but may be varied and altered without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
