Smoke exhaust device and its self-cleaning method, integrated stove

Abstract

The invention discloses a fume extractor, a self-cleaning method of the fume extractor and an integrated stove. The fume extractor comprises a fixed fume collection cavity (10), a lifting fume suckingcabinet (1), a spraying pump (12) and a spraying pipe (13). The fixed fume collection cavity (10) is arranged below a cooling bench (3) and connected with a fume extraction air flue assembly to extract fume outwards, the lifting fume sucking cabinet (1) can ascend to the position above the cooking bench or retract into the fixed fume collection cavity, the spraying pump pumps water to the spraying pipe, the spraying pipe is preferentially arranged in the fixed fume collection cavity to spray water to the side wall of the lifting fume sucking cabinet and the inner side wall of the fixed fume collection cavity for cleaning, the integrates stove comprises a dish washer (200), and the dish washer and the fume extractor (100) are arranged on the front portion and the rear portion below the cooking bench correspondingly. The self-cleaning method comprises a steam softening step, a spraying cleaning step and a dehumidifying step. Self cleaning of the inner wall of a flue can be achieved, thewhole machine is more sanitary, and bacteria are not likely to breed. In addition, steam can soften stubborn oil stain so as to be beneficial to removing oil stain, a fume extracting fan can extracthumidity outwards, and the whole machine is cleaner and more sanitary.

Description

technical field [0001] The invention belongs to the field of kitchen utensils, and in particular relates to a smoke exhaust device, a self-cleaning method thereof, and an integrated stove. Background technique [0002] Smoke extractors are indispensable in modern home kitchens. However, due to the limitations of the objective use environment and product structure, after the smoke exhaust device has been used for a period of time, the impeller and the inside of the volute in the suction and exhaust system will absorb a lot of oil due to the contact with the oil fume during use. The longer the time, the formed The more difficult it is to clean the oil, which requires regular disassembly for comprehensive cleaning. Otherwise, it will easily cause the load in the suction and discharge system of the whole machine to increase, and the performance index will decrease, which is specifically reflected in the decrease of suction and the increase of noise. If it is not cleaned in tim...

Problems solved by technology

Even if the self-cleaning method is adopted, it is limited to local places with a lot of oil pollution, such as the fan of the downdraft smoke exhaust device. In the prior art, the impeller is used to heat and then the centrifugal force is used to remove the grease at a high speed, or self-cleaning such as steam washing is used. However, there are generally defects such as long cleaning time and high temperature, which can easily accelerate the life of the device.

At present, there is no effective self-cleaning method for the up-and-down suction smoke exhaust device, especially for places with a long storage time and a lot of oil pollution, such as ignoring the cleaning of the inner wall of the flue

Moreover, when the spray cleaning method is used, the addition and replacement of cleaning agents and the storage of cleaning liquid and waste liquid all take up space and the operation process is cumbersome.
