It should be noted that the position relation (such as the top wall and the bottom wall of the ingredient-containing chamber 40b) of the components of the ingredient feeding device 2 will be changed along with overturning of the ingredient-receiving opening.

In addition, the flipping mechanism 11a and the compartment door driving mechanism 41b refer to an existing compartment door driving technology (for example, a patent with a patent publication number of CN103126515A, entitled “Programmable Controlled Intelligent Cooking Machine”, etc.), and description is not carried out here. Exemplarily, the compartment door driving mechanisms 41b include motors (not shown) correspondingly connected to the compartment doors 403b in a one-to-one mode, the motors are fixed to the bottom of the ingredient-containing chamber 40b, and the motors are electrically connected with the main control device 900 and correspondingly drive the doors 403b in a one-to-one mode.

In the embodiment of the present invention, preferably, the receiving space 404b is used for receiving a four-compartment ingredient container 20b (i.e., the multi-compartment ingredient container 20b with four individual compartments), and the number of the ingredient-dropping opening 402b and the number of the compartment doors 403b are four. Thus, a user can match main ingredients and accessory ingredients according to different dishes and stock the main ingredients and accessory ingredients in individual compartments (compartment A, compartment B, compartment C and compartment D) of a four-compartment ingredient container. Based on a preset recipe program, the ingredient feeding device 2 puts into the wok the food ingredients in different individual compartments at a predetermined time in a predetermined sequence. In this embodiment, the four individual compartments allow up to 24 combinations of putting sequence. A Chinese dish usually consists of one to three main ingredients and several accessory ingredients. For example, the dish “stir-fried Shredded Cabbage” has cabbage as a main ingredient, and chili and garlic as two accessory ingredients. The dish “Shredded Meat with Dry Tofu and Green Pepper” has shredded meat, dry tofu and green pepper as three main ingredients, and garlic and red pepper as two accessory ingredients. The raw ingredients are stocked in different individual compartments. Those raw ingredients that will be put into the wok at the same time can be stocked in a same individual compartment. In this embodiment, the raw ingredients are contained in four individual compartments, which means the raw ingredients can be put into the wok at four different moments, thus there are at most 24 combinations (ABCD, ABDC, ACBD, ACDB, ADBC, ADCB, BACD, BADC, BDAC, BDCA, BCAD, BCDA, CABD, CADB, CBAD, CBDA, CDAB, CDBA, DABC, DACB, DBAC, DBCA, DCAB, DCBA). A four-compartment container is already enough for most of the dishes. However, an over-four-compartment container, such as six-compartment container or eight-compartment container can be used to meet the requirement of some more complex dishes. It should be understood that the multi-compartment ingredient container 20b can comprise four individual compartments, six individual compartments or eight individual compartments, while the corresponding multi-compartment ingredient-containing chamber 40b should accordingly comprise four individual compartments, six individual compartments or individual eight compartments. In the present invention, all the raw ingredients for one dish, including the main ingredients and the accessory ingredients, are packaged and stocked in the individual compartments of the multi-compartment container. Therefore, the industrialization of the cooking machine is expectable. As a result, an industrial chain, including the production of agricultural products, pretreatment (cleaning and cutting etc.), package, delivery, distribution and consumption, can thus be established. This also leads to a new life style, since people no longer need to buy agricultural products in vegetable markets and thus less garbage will be produced. In addition, adopting a standard package helps guarantee food security.

Referring to FIGS. 7-10, as a further improved embodiment, the ingredient-containing chamber 40b includes a hollow square ingredient-feeding shell 405b and a supporting frame 406b, and the supporting frame 406b is used for supporting the inverted multi-compartment ingredient container 20b. The supporting frame 406b is provided with a transverse bar 4060b, a longitudinal bar 4061b and four side bars 4062b, the side bars 4062b are sequentially connected end to end to form a rectangular frame, the transverse bar 4060b is arranged between the middles of two opposite side bars 4062b by the two ends thereof connected with the two side bars 4062b in a one-to-one correspondence mode; the longitudinal bar 4061b is arranged between the middles of the other two opposite side bars 4062b of the rectangular frame by the two ends thereof connected with the other two side bars 406b2 in a one-to-one correspondence mode. In addition, the middle of the transverse bar 4060b is connected with the middle of the longitudinal bar 4061b in a crossed mode, namely, the supporting frame 406b is a framework shaped like a Chinese character ‘tian’. Thus, the transverse bar 4060b and the longitudinal bar 4061b divide a rectangular hollow area defined by the rectangular frame into the four rectangular ingredient-dropping openings 402b. Besides, one side face of the ingredient-feeding shell 405b is provided with the ingredient-receiving opening 407b, the bottom wall of the ingredient-feeding shell 405b is in an opening shape, and the top wall of the ingredient-feeding shell 405b is provided with the four water spraying openings 401b corresponding to the ingredient-dropping openings 402b in a one-to-one mode. Therefore, in the process that the ingredient feeding device 2 is washed by the spraying pieces 21, the compartment doors 403b which is arranged at the ingredient-dropping openings 402b and is in an open state can be washed by each of the water spraying openings 401b. The edges of the side end faces which are close to the bottom end faces of the ingredient-feeding shell 405b are connected with the side bars 4062b in a one-to-one correspondence mode, and in other words, the ingredient-feeding shell 405b and the supporting frame 406b are connected to each other to form the receiving space 404b, and the ingredient-receiving opening 407b is formed in one side wall of the ingredient-feeding shell 405b. In the embodiment of the present invention, when the multi-compartment ingredient container 20b is received in the receiving space 404b (that the full-automatic cooking machine is in a feeding process at the moment), with reference to FIGS. 10-13, the flipping mechanism 11a controls the ingredient feeding device 2 to flip, so that the multi-compartment ingredient container 20b in the ingredient-containing chamber 40b is inverted, the multi-compartment ingredient container 20b is inverted on the supporting frame 406b, food ingredients in the multi-compartment ingredient container 20b are dropped on the compartment doors 403b, and then the food ingredients in the multi-compartment ingredient container 20b can be dropped into the wok 1 by controlling the compartment doors 403b to be opened. Besides, after the multi-compartment ingredient container 20b is taken out of the material ingredient-containing chamber 40b (that the full-automatic cooking machine is running at a washing working position at the moment), the flipping mechanism 11a controls the ingredient feeding device 2 to flip, so that the ingredient-dropping opening 402b is aligned with the opening of the wok 1, and the water spraying openings 401b is aligned with the ingredient feeding device spraying piece 21. Referring now to FIGS. 14 and 15, when the multi-compartment ingredient container 20b is inverted on the supporting frame 406b, the food ingredient residues may adhere to the supporting frame 406b and the compartment doors 403b, so that the ingredient feeding device 2 is required to be washed, and the washing process can be referred to the embodiment described above and is not repeated here.

It should be noted that the material ingredient-containing chamber 40b can also be of other structure, for example, the material ingredient-containing chamber 40b can be of a hollow cylindrical structure with a plurality of water spraying openings 401b formed in the top wall and a plurality of ingredient-dropping openings 402b formed in the bottom end face, or the material ingredient-containing chamber 40b can be of a circular truncated cone structure with a plurality of water spraying openings 401b on the top wall and a plurality of ingredient-dropping openings 402b on the bottom end face, and specific limitation is not conducted here.

Referring now to FIGS. 7-10, in the embodiment described above, preferably the ingredient feeding device 2 further includes an ingredient-guiding shell of a hollow structure; the top of the ingredient-guiding shell is in an opening shape and is fixedly connected with the bottom of the supporting frame 406b, an ingredient-guiding opening 420b is formed in the bottom of the ingredient-guiding shell, the bottom of the ingredient-guiding shell is narrowed relative to the top of the ingredient-guiding shell, and therefore food ingredients and water can be conveniently guided into the wok 1 below the ingredient-guiding shell. Exemplarily, the ingredient-guiding shell comprises four ingredient-guiding plates 42b, the first ends of the four ingredient-guiding plates 42b are connected with the four side bars 4062b in a one-to-one correspondence mode, and the second ends opposite to the first ends of the ingredient-guiding plates 42b are bent towards the central axis of the rectangular frame (the central axis is perpendicular to the plane defined by the rectangular frame). The side edges of every two adjacent ingredient-guiding plates 42b are connected with each other, so that the ingredient-guiding plates 42b are connected with each other to form a cavity of an inverted halfpace-shaped structure, and the second ends of the ingredient-guiding plates 42b define the ingredient-guiding opening 420b for food ingredients/water falling from the ingredient-dropping opening 402b to fall into the wok 1. When the compartment doors 403b are opened, food ingredients dropped on the compartment doors 403b or water falling into the ingredient-containing chamber can fall into the cavity formed by the ingredient-guiding plates 42b from the ingredient-dropping openings 402b, and due to the fact that the second ends of the ingredient-guiding plates 42b are bent towards the central axis of the rectangular frame, namely the cavity is of an inverted halfpace-shaped structure, the food ingredients or water falling into the cavity can fall towards the ingredient-guiding opening 420b along the ingredient-guiding plates 42b, and therefore the food ingredients or water can fall into the wok 1 under the ingredient-guiding opening 420b in a more concentrated mode. When the full-automatic cooking machine is in a feeding process, namely the multi-compartment ingredient container 20b is inverted on the supporting frame 406 and the compartment doors 403b are opened, food ingredients will fall into the cavity formed by the ingredient-guiding plates 42b from the ingredient-dropping openings 402b and be guided to the ingredient-guiding opening 420b by the ingredient-guiding plates 42b, and then fall into the wok 1 from the ingredient-guiding opening 420b. With reference to FIG. 16, as food ingredients are in contact with the ingredient-guiding plates 42b, food ingredient residues may be adhered to the ingredient-guiding plates 42b, and the ingredient-guiding plates 42b are also required to be flushed. The process of flushing the ingredient-guiding plates 42b is as follows: the water falling from the ingredient-containing chamber 40b can be guided to the ingredient-guiding opening 420b along the ingredient-guiding plates 42b, and then fall into the wok 1 from the ingredient-guiding opening 420b, so that the ingredient-guiding plates 42b can be flushed.

The human-machine operation interface 14c is provided on an outer side of the outer shell 1c (e.g. may be provided on a top portion or a side portion outside the outer shell 1c). The human-machine operation interface 14c, the furnace body device 24c, the wok rotating device 25c, the wok working position controlling device 21c and the wok moving control device 22c are electrically connected with the control device 13c so as to receive control commands sent by the control device 13c according to a preset recipe program and perform corresponding operations according to the control commands.

In the embodiment of the present invention, in order to improve the air tightness of the shell and prevent the cooking fume in the shell from being directly discharged out of the shell, a cooking cavity 100 which is arranged in a sealed manner is formed in the inner shell 1d, and the whole wok mechanism (except the wok moving control device 22c) is arranged in the cooking cavity 100, so that cooking fume generated by the wok 20c can be gathered in the cooking cavity 100.

Referring to FIGS. 39 and 42, the cooking machine further comprises a cooking fume inlet pipe 311c and a wok lid 23c which is fixed in the inner shell 1d and used for being matched with an opening of the wok 20c; one end of the cooking fume inlet pipe 311c is connected with an opening (exhaust port) penetrating through the wok lid 23c, and the other end of the cooking fume inlet pipe 311c penetrates through the cooking fume inlet 321c in a sealed manner and is communicated with the interior of the cooking fume treatment device 3c; the cooking fume outlet 322c of the cooking fume treatment device 3c is communicated with the interior of the inner shell 1d (and the interior of the closed cooking cavity).

Specifically, the exhaust port (not shown) penetrates through the center of the wok lid 23c, and the wok lid 23c is rotatably connected with one end of the cooking fume inlet pipe 311c, so that the wok lid 23c can rotate around the cooking fume inlet pipe 311c. The moving direction of the wok 20c is parallel to the central axis of the wok lid 23c; when the wok 20c is turned to a cooking position, the opening of the wok 20c faces the wok lid 23c, and the central axis of the wok 20c coincides with the central axis of the wok lid 23c. Therefore, when cooking is needed, the wok 20c is turned to a cooking working position by the wok working position controlling device 21c, the opening of the wok 20c faces the wok lid 23c, then the wok 20c is moved by the wok moving control device 22c to enable the wok lid 23c to cover the opening of the wok 20c, and then the wok 20c is controlled to rotate by the wok rotating device 25c to perform cooking operation, so that in the cooking process, cooking fume generated in the wok 20c can enter the cooking fume treatment device 3c from the cooking fume inlet pipe 311c in a centralized mode. After the cooking operation is completed, the wok 20c needs to be opened, and the wok 20c is moved by the wok moving control device 22c, so that the wok lid 23c is separated from the wok 20c.

The wok lid 23c comprises a wok lid plate and a wok lid sealing container (not shown); the wok lid sealing container comprises a fixing part installed on the wok lid plate and a sealing strip which can be arranged on the periphery of the fixing part in a relatively rotating and sleeving mode. An area enclosed by the sealing strip is matched with the opening of the wok in size and shape. Therefore, when the wok lid 23c seals the opening of the wok 20c with the sealing strip and the wok rotates, the sealing strip rotates along with the wok, so that the resistance of the wok as it rotates is reduced.

The exhaust port communicated with the cooking fume treatment device 3c is formed in the wok lid plate; the fixed part is provided with a first communication opening communicated with the cooking fume channel opening; the wok lid plate is provided with an seasoning adding opening communicated with an automatic seasoning adding device of the cooking machine; the fixing part is provided with a second communication opening communicated with the seasoning adding opening.

That is, the cooking fume channel opening and the seasoning adding opening are achieved through the common channel opening at the same time, and seasoning adding or cooking fume extracting can be performed through the common channel opening. Preferably, the fixing part is detachably installed on the wok lid plate.

Therefore, according to the cooking fume treatment system provided by the embodiment of the present invention, the closed cooking cavity 100 is formed in the inner cavity of the inner shell 1d, the wok mechanism (comprising the wok and the wok lid) is arranged in the closed cooking cavity 100, and the wok is closed by the wok lid during cooking, so that a first-layer of closed cooking space is formed in the inner cavity of the wok, and cooking fume generated by the wok 20c during closed cooking is discharged to a cooking fume treatment device 3c from the exhaust port of the wok lid 23c for treatment; in addition, under a second-layer of sealed cooking space of the sealed cooking cavity 100, even if the cooking fume escaping from the wok 20c in the cooking process is limited in the cooking cavity, the cooking fume is purified by the cooking fume treatment device (for example, after the wok 20c is separated from the wok lid 23c, the cooking fume is discharged from an exhaust port of the wok lid 23c) and then is discharged, so that the situation that cooking fume generated in the cooking process is directly exhausted outwards to pollute the surrounding environment is avoided.

For ease of understanding, the structure of the cooking fume treatment device 3c is described in detail below with reference to FIGS. 41-48:

Preferably, referring to FIGS. 41-48, the cooking fume treatment device 3c is arranged between the outer shell 1c and the inner shell 1d, and the cooking fume treatment device 3c comprises a box body 32c, a fan 33c, a cooking fume filtering assembly 34c, a micro refrigerator 35c, a water circulation pipeline 36c and a water pump 37c. Specifically, the box body 32c is provided with a water adding opening 320c, a cooking fume inlet 321c and a cooking fume outlet 322c, an cooking fume channel 323c communicating the cooking fume inlet 321c with the cooking fume outlet 322c is formed in the box body 32c, and the cooking fume inlet 321c and the cooking fume outlet 322c communicate with the cooking cavity 100. The fan 33c is used for drawing cooking fume into the box body 32c from the cooking fume inlet 321c and exhausting the cooking fume from the cooking fume outlet 322c. The cooking fume filtering assembly 34c is arranged in the cooking fume channel 323c. The micro refrigerator 35c is preferably a semiconductor refrigerator, and at least one refrigeration sheet 350c of the micro refrigerator 35c is arranged in the cooking fume channel 323c; at least one first water outlet 360c of the water circulation pipeline 36c is positioned at the upper part in the box body 32c and is positioned right above the cooking fume channel 323c, and at least one first water inlet 361c of the water circulation pipeline 36c is positioned at the lower part in the box body 32c; the water pump 37c is arranged in the water circulation pipeline 36c. The fan 33c, the micro refrigerator 35c and the water pump 37c are electrically connected with the control device 13c so as to receive control commands sent by the control device 13c according to a preset recipe program and perform corresponding operations according to the control commands.

The working principle of the cooking fume treatment device 3c provide by the embodiment of the invention is as follows: in the cooking process of the cooking machine, cooking fume can be continuously generated in an inner cavity of the wok in the cooking cavity 100. Under the pressurization blowing effect of the fan 33c, the cooking fume in the inner cavity of the wok can enter the cooking fume channel 323c from the cooking fume inlet 321c and then can be filtered by the cooking fume filtering assembly 34c. In this process, the temperature of the cooking fume channel 323c can be reduced when the refrigeration sheet 350c of the micro refrigerator 35c works, so that cooking fume entering the cooking fume channel 323c is condensed, and the cooking fume filtering assembly 34c can better filter the cooking fume. Under the action of the water pump 37c, the water circulation pipeline 36c continuously sprays water to the cooking fume filtering assembly 34c located in the cooking fume channel 323c from the first water outlet 360c, so that the temperature in the cooking fume channel 323c is further reduced, the cooking fume can be effectively condensed, and the cooking fume filtering assembly 34c can be used for better filtering the cooking fume. The water falling to the bottom in the box body 32c can enter the water circulation pipeline 36c again under the action of the water pump 37c. In addition, due to the fact that the cooking fume inlet 321c and the cooking fume outlet 322c are both communicated with the cooking cavity 100 arranged in the sealed manner, after the cooking fume in the wok enters the box body 32c from the cooking fume inlet 321c for cooking fume treatment, residual cooking fume enters the cooking cavity 100 from the cooking fume outlet 322c again. In the cooking process, the cooking fume gas escaping out of the wok and the cooking fume gas entering the cooking cavity 100 from the cooking fume outlet 322c of the cooking fume treatment device 3c continue to enter the box body 32c from the cooking fume inlet 321c to be subjected to cooking fume treatment, and the process is continuously repeated; therefor, the cooking fume in the cooking cavity 100 can be effectively treated without being discharged to the outside, and zero emission of the cooking fume is achieved.

It will be appreciated that micro refrigerator 35 can be other existing micro refrigerating devices, and the details are not described herein.

It should be noted that referring to FIG. 44, when the water in the box body 32c and the water circulation pipeline 36c is insufficient, water can be added to the box body 32c from the water adding opening 320c. Preferably, referring to FIG. 44, the water adding opening 320c is formed in the top of the box body 32c, a water adding pipe 325c penetrates through the water adding opening 320c in a sealed manner, one end of the water adding pipe 325c penetrates into the box body 32c, and therefore water can be added into the box body 32c from the water adding pipe 325c. Exemplarily, the water adding pipe 325c can be communicated with an external water source, a water pipe valve (not shown) can be arranged in the water adding pipe 325c, and when water needs to be added into the box body 32c, the water pipe valve can be controlled to be opened. It can be understood that cooking fume cleaning liquid can be added into the box body 32c from the water adding opening 320c, so that the cooking fume cleaning liquid added into the box body 32c can be mixed with water in the box body 32c, and then the mixture is conveyed to the first water outlet 360c from the water circulation pipeline 36c and continuously sprayed to the cooking fume filtering assembly 34c below the first water outlet 360c so as to clean the cooking fume filtering assembly 34c, thus the cooking fume filtering assembly 34c does not need to be replaced frequently.

Therefore, by arranging the spraying plate 38c, water sprayed from the first water outlet 360c can be uniformly sprayed into the cooking fume channel 323c, so that the cooking fume channel 323c can be cooled more effectively.

Illustratively, referring to FIGS. 44-46, the cooking fume treatment device 3c further comprises a cooling body 39c of a hollow structure, a second water inlet 390c of the cooling body 39c is communicated with a water outlet pipe section of the water circulation pipeline 36c, a second water outlet 391c of the cooling body 39c is located above the spraying plate 38c, and a second water outlet 391c of the cooling body 39c is located below the spraying plate 38c, so that water in the water outlet pipe section of the water circulation pipeline 36c can flow into the cooling body 39c from the second water inlet 390c and then be sprayed onto the spraying plate 38c from the second water outlet 391c. In order to enable the cooling body 39c to cool the heat conduction part 351c of the micro refrigerator 35c, the cooling body 39c is in contact with the heat conduction part 351c of the micro refrigerator 35c, so that cold water continuously flowing into the cooling body 39c can continuously take away heat of the heat conduction part 351c to enable the heat conduction part 351c to be cooled, thereby enabling the micro refrigerator 35c to better perform refrigeration work. It should be noted that the cooling body 39c may be of a box structure or a bent pipeline structure or the like, which is not specifically limited herein.

The containing cavity 310c is only communicated with the heat dissipation opening 324c, so that heat generated by the heat conduction part 351c can only be discharged from the heat dissipation opening 324 and cannot enter the cooking fume channel 323c. It should be noted that the containing cavity 310c may be a hollow cubic structure or a hollow cylindrical structure or the like, which is not specifically limited herein.

In the embodiment of the present invention, preferably, referring to FIGS. 42-44, the cooking fume treatment device 3c further comprises a cooking fume inlet pipe 311c (which can be matched with the wok lid 23c mentioned below) and a spraying cavity 312c with an opening in the top, and the top of the spraying cavity 312c is fixed to the bottom of the part, provided with the spraying holes 380c, of the spraying plate 38c; the bottom of the spraying cavity 312c is positioned above the bottom in the box body 32c and is provided with a through opening 3120c; one end of the cooking fume inlet pipe 311c penetrates through the cooking fume inlet 321c in a sealed manner in the direction towards the interior of the box body 32c and penetrates into the spraying cavity 312c in a sealed manner, the other end of the cooking fume inlet pipe 311c penetrates into the cooking cavity 100, and therefore under the action of the fan 33c, the cooking fume in the cooking cavity 100 enters the spraying cavity 312c from the cooking fume inlet pipe 311c, and then the cooking fume enters an area between the box body 32c and the spraying cavity 312c from the through opening 3120c, and is finally discharged from the cooking fume outlet 322c. In the spraying cavity 312c, a cooking fume spraying channel 3121c which is arranged in an extending mode is formed between one end of the cooking fume inlet pipe 311c and the through opening 3120c, so that the path of cooking fume entering the spraying cavity 312c can become longer, and the condensation and filtration of the cooking fume are better facilitated. At least one cooking fume filtering layer 340c is arranged in the cooking fume spraying channel 3121c, and the at least one refrigerating sheet 350c is arranged in the spraying cavity 312c and is distributed right above the cooking fume spraying channel 3121c. In addition, the bottom of each section of the cooking fume spraying channel 3121c is communicated with the through opening 3120c, so that water sprayed into the cooking fume spraying channel 3121c from the spraying holes 380 of the spraying plate 38c can be discharged to the bottom in the box body 32c from the through opening 3120c.

Illustratively, the cooking fume treatment device 3c further comprises a transverse partition plate 314c, a first longitudinal partition plate 313c, a second longitudinal partition plate 315c and a third longitudinal partition plate 316c, all of which are shown in FIGS. 44-46; the first longitudinal partition plate 313c is longitudinally arranged between the spraying plate 38c and the bottom in the box body 32c, so that an area between the spraying plate 38c and the bottom in the box body 32c is divided into two parts, and a cooking fume channel opening 3130c is formed between the bottom of the first longitudinal partition plate 313 and the bottom in the box body 32c. The transverse partition plate 314 is located between the spraying plate 38c and the bottom in the box body 32c and transversely arranged between the first longitudinal partition plate 313c and a side plate, opposite to the first longitudinal partition plate 313c, of the box body 32c. Thus, the transverse partition plate 314c, the first longitudinal partition plate 313c, the spraying plate 38c and the corresponding inner side wall of the box body 32c can define the spraying cavity 312c.

In order to extend the cooking fume spraying channel 3121c formed between the end of the cooking fume inlet pipe 311c and the through opening 3120c, for example, as shown in FIGS. 44-46, the second longitudinal partition plate 315c is disposed longitudinally between the first longitudinal partition plate 313c and the side plate of the box body 32c, the top of the second longitudinal partition plate 315c is connected to the bottom of the spraying plate 38c in a sealed manner, and the bottom of the second longitudinal partition plate 315c is spaced from the top of the transverse partition plate 314c; the third longitudinal partition plate 316c is longitudinally arranged between the second longitudinal partition plate 315c and the side plate of the box body 32c, the top of the third longitudinal partition plate 316 and the bottom of the spraying plate 38c are arranged in a spaced mode, and the bottom of the third longitudinal partition plate 316c is fixed to the top of the transverse partition plate 314. Thus, at the other end of the smoke pipe between the first longitudinal partition plate 313c and the second longitudinal partition plate 315c, cooking fume exhausted by the cooking fume exhaust pipe can firstly pass through the area between the first longitudinal partition plate 313c and the second longitudinal partition plate 315, then pass through the area between the second longitudinal partition plate 315c and the third longitudinal partition plate 316c, and finally passes through an area between the third longitudinal partition plate 316c and the inner side wall of the corresponding box body 32c. Besides, the cooking fume outlet 322c is formed in the other side plate, opposite to the side plate, of the box body 32c and located below the spraying plate 38c, the through opening 3120c is formed in the transverse partition plate 314c, and the through opening 3120c is located between the third longitudinal partition plate 316 and the side plate (adjacent to and opposite to the third partition plate) of the box body 32c. Cooking fume entering the spraying cavity 312c can be discharged to the position between the transverse partition plate 314c and the bottom in the box body 32c from the through opening 3120c, and then is discharged out from the cooking fume channel opening 3130 and the cooking fume outlet 322c in sequence. Therefore, by arranging the partition plates in the box body 32c, the passing path of the cooking fume entering the box body 32c can be lengthened, which is more beneficial to the condensation and filtration of the cooking fume. In order to enable water sprayed between the second longitudinal partition plate and the third longitudinal partition plate to smoothly flow to the through opening 3120c, a gap 3160c is formed between the bottom of the third longitudinal partition plate and the transverse partition plate 314c.

It should be noted that the spraying cavity 312c may also be a hollow cylindrical structure or other structure or the like, which is not specifically limited herein. In addition, the extending mode of the cooking fume spraying channel 3121c in the spraying cavity 312c can also be other arrangement modes, for example, the cooking fume spraying channel 3121c can be of a spiral structure from top to bottom or a spiral structure from inside to outside on the horizontal plane, which is not limited herein.

As a further improvement on the cooking fume treatment device 3c, a secondary cooking fume treatment device is additionally arranged on the basis of the cooking fume treatment device 3c, and cooking fume treated by the cooking fume treatment device 3c needs to be treated by the secondary cooking fume treatment device and then flows back into the cooking cavity 100, that is, the cooking fume outlet 322c of the cooking fume treatment device 3c is communicated with the interior of the cooking cavity 100 via the secondary cooking fume treatment device instead of being directly connected with the interior of the cooking cavity 100. Specifically, referring to FIGS. 44-47, the secondary cooking fume treatment device comprises a first filter box 317c, the first filter box 317c is provided with a fume inlet 3170c and a fume outlet 3171c, the fume inlet 3170c is communicated with the cooking fume outlet 322c of the cooking fume treatment device 3c, and the fume outlet 3171c is communicated with the interior of the cooking cavity 100, thus, cooking fume entering the box body 32c from the cooking fume inlet 321c enters the first filter box 317c from the cooking fume outlet 322c and then enters the cooking cavity 100 again from the fume outlet 3171c. In addition, at least one cooking fume filter layer 3172c is arranged between the fume inlet 3170c and the fume outlet 3171c, so that the cooking fume treated in the box body 32c can be filtered by the cooking fume filter layer 3172c in the first filter box 317c after entering the first filter box 317c, and the cooking fume can be treated more effectively.

Preferably, referring to FIGS. 44-47, the cooking fume treatment device 3c further comprises a draining pipe 3173c. The fume inlet 3170c is formed in the top of the first filter box 317c, and the fume outlet 3171c is formed in the bottom of the first filter box 317c, so that cooking fume entering the first filter box 317c can sequentially pass through the cooking fume filter layer 3172c arranged between the fume inlet 3170c and the fume outlet 3171c from top to bottom. In addition, the first filter box 317c is located below the box body 32c, one end of the draining pipe 3173c is connected with the top of the first filter box 317c, and the other end of the draining pipe 3173c penetrates into the box body 32c in a sealed manner and protrudes relative to the bottom in the box body 32c, thus, when water is added into the box body 32c to enable the water level in the box body 32c to be higher than the set height of the other end of the draining pipe 3173c, the water in the box body 32c can flow into the first filter box 317c from the draining pipe 3173c and pass through the cooking fume filter layer arranged between the fume inlet 3170c and the fume outlet 3171c from top to bottom, so that the first filter box 317c can be effectively cooled, and cooking fume entering the first filter box 317c can be effectively condensed.

Water falling into the first filter box 317c can be discharged to the bottom of the cooking cavity 100 from the fume outlet 3171c and then discharged out from a water outlet 101c (the water outlet 101c is communicated with a bottom opening of the cooking cavity 100) formed in the bottom of the outer shell 1c. It should be noted that when the water adding opening 320c is formed in the top of the box body 32c, water is added into the box body 32c from the water adding opening 320c, so that the water passes through the spraying plate 38c and then can uniformly spray the cooking fume filtering assembly 34c, the cooking fume filtering assembly 34c can be cooled, and the cooking fume filtering assembly 34c can be cleaned to a certain extent; when the water level of the accumulated water falling into the bottom in the box body 32c is higher, the accumulated water falls into the first filter box 317c from the draining pipe 3173c, so that the cooking fume filter layer 3172c in the first filter box 317c is cleaned, then is discharged into the cooking cavity 100 from the fume outlet 3171c and finally discharged from the water outlet 101c. In order to enhance the cooking fume cleaning effect on the cooking fume filtering assembly 34c, cooking fume cleaning liquid can be added into the box body 32c from the water adding opening 320c.

As a further improvement of the above embodiment, referring to FIGS. 44-47, the secondary cooking fume treatment device further comprises a cooking fume outlet pipe 318c and a second filter box 319c, the second filter box 319c is communicated with the cooking fume outlet 322c via the fan 33c and communicated with the fume inlet 3170c of the first filter box 317c via the cooking fume outlet pipe 318c, and at least one cooking fume filter layer 3190c is arranged in the second filter box 319c. The cooking fume discharged from the cooking fume outlet 322c of the box body 32c enters the second filter box 319c, and enters the first filter box 317c to be filtered again after being filtered by the cooking fume filter layer 3190c in the second filter box 319, so that the cooking fume filtering effect can be further improved.

It should be noted that the cooking fume filtering layer of the above embodiments of the present invention may be made of a material which has good adsorption capacity on cooking fume and a good thermal conductivity, for example, the cooking fume filtering layer may be made of steel wire balls or stacked metal wire meshes arranged and the like, and is not limited in particular herein.

According to the analysis, in the embodiment of the present invention, the cooking fume generated in the cooking process can be effectively treated by arranging the cooking fume treatment device 3c, so that pollution of the cooking fume to the environment can be effectively avoided. Moreover, the cooking fume primarily treated by the cooking fume treatment device 3c sequentially enters the second filter box 319c and the first filter box 317c of the secondary cooking fume treatment device to be filtered twice and then returns to the cooking cavity to be circularly treated, so that zero cooking fume emission in a real sense is realized.

Moreover, as a further optimized design of the cooking fume treatment system of the embodiment, referring to FIG. 54, on the basis of the cooking fume treatment system, a second exhaust port 140c is directly formed in the inner shell 1d, the interior of the cooking cavity 100 communicates with the cooking fume inlet 321c of the cooking fume treatment device 3c via the second exhaust port 140c, so that the cooking fume in the cooking cavity 100 can be directly discharged to the cooking fume treatment device 3c from the second exhaust port 140c for cooking fume treatment. Thus, the cooking fume escaping out from the wok to the cooking cavity 100 in the cooking process and the cooking fume flowing back into the cooking cavity 100 after being treated by the cooking fume treatment device 3c/the secondary cooking fume treatment device can be exhausted to the cooking fume treatment device 3c from the second exhaust port 140c for cooking fume treatment. Therefore, as an improved design, the cooking fume generated in the closed cooking process of the wok 20c is discharged to the cooking fume treatment device 3c from the exhaust port of the wok lid for cooking fume treatment; the cooking fume escaping out from the wok to the cooking cavity 100 is discharged to the cooking fume treatment device 3c from the second exhaust port 140c for cooking fume treatment when the wok 20c is opened, so that the cooking fume treatment efficiency and effect are further improved.
