The air intake assembly 3 includes an air intake channel 31 disposed at the rear side of the oven body 2 and below the first box 12, and an air intake 32 disposed at a corresponding position at the rear portion of the fume collecting hood 13, and two ends of the air intake channel 31 are respectively communicated with the air intake 32 and the first box 12. Because the air inlet channel 31 and the air inlet 32 are close to the wall, when the oil smoke contacts the smoke collecting cover 13, the wall attachment effect of the oil smoke can be utilized, and the oil smoke rising upwards to the smoke collecting cover 13 is pulled backwards and is taken away quickly by the air inlet 32. The air inlet channel 31 is designed in a linear type, so that the efficiency of oil smoke absorption is improved, the energy consumption is reduced, and more space is provided for the oven main body 2. An oil screen 33 is arranged at the air inlet 32 and used for separating oil from the sucked oil smoke.

In order to adapt the fan 11 to the air intake channel 31, the fan 11 is a back suction fan (the suction port of the fan 11 faces the rear wall). Because the suction inlet of the back suction type fan 11 is positioned at the back side, the influence of the noise generated by the operation of the fan 11 on a user when the user uses the range hood main body 1 can be effectively reduced, and the experience of the user is improved.

The internal circulation assembly 4 comprises a circulation pipeline 41, an air outlet pipeline 42 arranged on the air outlet cover 14 and a purification assembly 43 arranged in the circulation pipeline 41. The air outlet duct 42 is a tee duct, one of the openings is an inlet 421 connected to the air outlet housing 14, the inlet 421 is opened at the bottom so as to be connected to the air outlet housing 14, the other opening is a first outlet 422 connected to the circulation duct 41, the first outlet 422 is opened at the side so as to be connected to the upper end of the circulation duct 42, the remaining one opening is a second outlet 423 connected to the common flue, and the second outlet 423 is opened at the top so as to be connected to the common flue. An inner circulation inlet 25 is opened on one of the left and right sides of the second casing 21 of the oven body 2, and the lower end of the circulation duct 41 is connected with the inner circulation inlet 25. The circulation duct 41 may be disposed adjacent to the first casing 12 of the range hood main body 1.

When the range hood body 1 and the oven body 2 simultaneously operate, the first check valve 424 is disposed at the first outlet 422, and the second check valve 425 is disposed at the second outlet 423, the first check valve 424 can be opened to enable the air outlet cover 14 (the first box 12) of the range hood body 1 to be communicated with the circulation pipeline 41 (the air outlet cover 14 is communicated with the circulation pipeline 41 in a one-way manner), and the second check valve 425 is closed to close an air flow passage between the air outlet cover 14 (the first box 12) and the common flue. When the range hood main body 1 works alone (the oven main body 2 does not work at this time), or when the oven main body 2 works alone (the range hood main body 1 does not work at this time), the first check valve 424 closes to close the airflow path between the air outlet cover 14 (the first box 12) and the circulation duct 41, and the second check valve 425 opens to communicate the air outlet cover 14 (the first box 12) and the common flue (the air outlet cover 14 communicates to the circulation duct 41 in one way).

The purification assembly 43 is a combined purification assembly including a perforated screen 431, an activated carbon screen 432 and a HEPA screen 433, which are arranged in this order from upstream to downstream on the soot flow path. Because the fan 11 of the range hood main body 1 adopts a centrifugal fan, large particles are thrown out under the centrifugal action of the centrifugal fan, and therefore, only small particles and part of VOCS (volatile organic compounds) need to be filtered to form clean hot air through the combined purification component 43. The hot air blown into the oven main body 2 through the circulation duct 41 makes the temperature field inside the oven main body 2 more uniform.

Correspondingly, the oil smoke concentration sensor 26 is installed at a side corner of the second box 21 of the oven main body 2, so that the oil smoke concentration in the second box 21 can be detected, and the detected result is transmitted to the control module of the range hood main body 1, thereby adjusting the air volume of the fan 11 in real time.

An operation panel 27 is provided on the front side of the second casing 21, and a display screen is provided on the operation panel 27. The display screen can play the video, makes things convenient for the culinary art person to do the culinary art when watching the culinary art video, lets the culinary art person can accomplish multichannel cooked food in the short time in step to through foretell air inlet subassembly 3 and fan 11's the mode that sets up, no oil smoke disturbs during the realization operation.

The steam assembly 5 comprises a steam generator 51, a first steam outlet pipeline 52 and a second steam outlet pipeline 53, wherein the steam generator 51 is used for generating steam, the first steam outlet pipeline 52 is communicated with the first box 12 of the range hood main body 1, and the second steam outlet pipeline 53 is communicated with the circulating pipeline 41 and is connected with the purifying assembly 43 at a position downstream. The steam generator 51 may be disposed outside the first casing 11 of the range hood main body 1 so as to fix the position of the steam assembly 5, preferably, adjacent to the circulation pipe 41, so as to reduce the length of the second steam outlet pipe 53.

Therefore, steam generated by the steam generator 51 can enter the first box body 12 through the first steam outlet pipeline 52, so that the steam is matched with a cleaning agent to clean the impeller of the fan 11, and the inside of the impeller is cleaned; and also enters the circulation duct 41 through the second steam outlet 53, so that the purified air is combined to form air with a certain humidity, and the air enters the oven main body 2 to maintain the humidity inside the oven main body 2. When the oven main body 2 does not work, the fan 11 in the range hood main body 1 can also provide power to input steam into the oven main body 2 to clean the interior of the second box body 21 of the oven main body 2. The waste water cleaned by the oven main body 2 is directly introduced into the oil cup of the range hood main body 1 through the bottom of the second box body 21.

The electric valve assembly 6 is disposed at the air outlet 22 at the top of the second box 21 of the oven body 2, and includes an electric valve 61 and a driving device 62 for driving the electric valve 61 to rotate. The shape and size of the electric valve 61 are adapted to those of the air outlet 22 of the second box 21, and the driving device 62 may be electrically connected to the control module of the oven body 2. The electric valve 61 is fixedly connected to a rotary shaft 63, the rotary shaft 63 is rotatably connected to front and rear side walls of the first casing 12, and the rotary shaft 63 extends laterally in the front-rear direction. The driving device 62 may be a motor, which is connected to the rotating shaft 63 through a gear transmission mechanism 64, and the structure of the driving device 62 for driving the rotating shaft 63 to rotate through the gear transmission mechanism 64 may be a conventional structure. So that when the motor is running, the rotating shaft 63 can be driven to drive the electric valve 61 to rotate. Because the oven main body 2 and the range hood main body 1 can work independently, the opening area of the air outlet 22 of the oven main body 2 (the opening degree of the electric valve 61) can be controlled by arranging the electric valve assembly 6. The electrically operated valve 61 may be linked with the first check valve 424 and the second check valve 425 of the air outlet duct 42.

When the oven body 2 does not work, the electric valve 61 closes the air outlet 22, and meanwhile, the first check valve 424 and the second check valve 425 of the air outlet pipeline 42 are closed and opened, so that the range hood body 1 is used as an independent component; when the toaster body 2 is operated, the driving means 62 may drive the electric valve 61 to be opened at a desired opening degree according to a mode used by a user, so that the second casing 21 and the first casing 12 are communicated. For example, when the oven body 2 adopts a barbecue mode, the concentration of oil smoke inside the second box 21 is relatively high, and the opening degree of the air outlet 22 is adjusted to be relatively large; when the baking mode is adopted, the oil smoke concentration inside the second box 21 is relatively low, and the opening degree of the electric valve 61 is adjusted to be relatively small. Because the oven main body 2 is in different working modes, the oil smoke concentration inside the second box body 21 is very different, so the oil smoke concentration inside the second box body 21 needs to be roughly adjusted by controlling the opening degree of the electric valve 61, otherwise, when the oil smoke concentration inside the second box body 21 is very high, if the opening degree of the electric valve 61 is not increased, the concentration detected by the oil smoke concentration sensor 26 is too high, which causes the air volume of the fan 11 of the range hood main body 1 to be greatly increased, and further causes the noise to be too large.

On the basis of the electric valve component 6, the air quantity of the range hood main body 1 can be accurately adjusted by combining with the oil smoke concentration sensor 26 in the oven main body 2. When the range hood main body 1 and the oven main body 2 work together, if the concentration of oil smoke inside the oven main body 2 is high, the air volume of the fan 11 of the range hood main body 1 needs to be increased, and if the concentration of oil smoke inside the oven main body 2 is low, the oil smoke absorption effect of the range hood main body 1 needs to be considered, so the cooking oil smoke volume needs to be combined, and if the cooking oil smoke is low, the cooking oil smoke volume can be adjusted to be small; if the cooking oil fume is large, the cooking oil fume is adjusted to be large in air volume. When the oven main body 2 works alone, the air volume entering the range hood main body 1 is linearly adjusted according to the oil smoke concentration inside the oven main body 2, the oil smoke concentration inside the oven main body 2 is increased, the air volume entering the range hood main body 1 is increased, the oil smoke concentration inside the oven main body 2 is reduced, and the air volume entering the range hood main body 1 is reduced.

The integrated range hood is formed by integrating the functions of the range hood and the oven, so that the kitchen space is effectively saved, the circulating pipeline is arranged between the fan of the range hood and the oven main body, the hot circulating fan of the oven is replaced by the air outlet of the fan, the components and the energy consumption are reduced, and the temperature field in the oven is more uniform; the opening of the electric valve can be determined according to the operating mode of the oven, so that the oil smoke problem of the kitchen oven is solved in a targeted manner, and the air quality and the life quality of the kitchen are improved; an oil smoke concentration sensor is arranged in the oven, so that the air quantity of the range hood can be accurately adjusted by detecting the oil smoke concentration, and the energy consumption is reduced; the cleaning of the fan of the range hood and the cleaning of the interior of the oven are realized by arranging the steam component; through the innovation of range hood air inlet mode, air inlet channel is smooth and easy to provide the space for the oven.
