The upper end of the machine body 1000 is a cooking bench, a plurality of burners 1100 are usually arranged on the cooking bench, the machine head 100 is arranged at the edge of the machine body 1000 along the length direction, the machine head 100 comprises a shell, the shell comprises a back plate, a smoke baffle plate, a top plate and side plates connected to the edges of two sides of the back plate, the smoke baffle plate, the top plate, the back plate and the side plates can be sheet metal parts, the two side plates correspond to two side walls 112 of the flue 110, the back plate corresponds to a rear wall 113 of the flue 110, the smoke baffle plate corresponds to a front wall 114 of the flue 110, and the back plate, the smoke baffle plate and the two side plates are connected end to form the flue 110. The height of the smoke barrier is lower than the back plate so that the top surface of the smoke barrier, the bottom surface of the top plate and the surfaces of the two side plates facing each other form a smoke suction opening 111. Typically, the smoking openings 111 are provided as rectangular holes, which may be single holes or a plurality of rectangular holes side by side. Accordingly, the flue 110 is generally an elongated slit. To fit a plurality of cookware arranged on an integrated stove. The cooker is placed on the burner 1100 of the cooking bench, and during cooking, a large amount of upward-rising oil smoke is generated, and the fan is operated to suck the oil smoke into the flue 110 from the smoke suction port 111. The smoke suction opening 111 is positioned above the cooker, so that most of the oil smoke can be sucked away.

In order to enhance the cleaning effect of the inner wall of the flue 110, the integrated kitchen of the present embodiment includes a first cleaning module and a second cleaning module. The heating means of the first cleaning assembly can directly heat the water into steam, which is delivered to the nozzle 310 by the first delivery means for ejection. The water can be heated to a certain temperature to form hot water, and the hot water is conveyed to the spray pipe 310 through the first conveying device, and atomized by water pressure to enlarge the spraying range. The nozzle 310 is parallel to the rear wall 113 and is located in the middle area of the rear wall, i.e. in the height range of 1/4 to 3/4 of the rear wall, and compared with the conventional art in which the nozzle 310 is disposed at the top of the flue 110, the nozzle 310 of this embodiment can spray hot water or steam from the front to the inner wall of the flue 110, so as to shorten the spraying distance of the steam or hot water, thereby reducing the heat loss of the steam or hot water, improving the heating effect on the greasy dirt, and improving the cleaning effect of the greasy dirt. The side of the nozzle 310 is provided with a plurality of openings according to the length of the flue 110 so that the steam can be spread over the inner wall of the flue 110. In the vertical direction, a plurality of nozzles 310 can also be provided.

The heating device can be disposed in the first liquid storage device and can also be disposed on the hot water delivery path, and the closer the heating device is to the spout 310, the less heat loss is in the delivery process of the hot water or steam. Therefore, it is possible to enhance the cleaning effect of the oil stain by disposing the heating means at a position close to the nozzle 310.

The spraying device 210 of the second cleaning module may be a device capable of spraying liquid, such as a spray head or a spray pipe, where a coverage area of the cleaning liquid sprayed by the spraying device 210 is cone-shaped, and the spraying device 210 is disposed on the side wall 112 of the flue 110 and faces the inside of the flue 110, i.e. a spraying direction of the spraying device 210 is consistent with a length direction of the flue 110, so as to adapt to cleaning of an inner wall of the long and narrow flue 110. Therefore, in this embodiment, only two injection devices 210 are disposed on two side walls 112, and the heights of the two injection devices 210 may be identical, so that the two injection devices 210 form a hedging structure. When the two opposite-flushing type injection devices 210 inject the washing liquid, the washing liquid can be enabled to be distributed on the whole inner wall of the flue 110, the cleaning effect is improved, the structure is simpler, and the manufacturing cost is reduced.

Further, it will be appreciated that the smoking openings 111 are facing the back plate and thus the back wall 113 of the flue 110 is the primary contamination area for oil stains. Based on this, in order to facilitate the flow of the oil stain, the surface of the back plate close to the flue 110 is set to be a smooth surface so as to accelerate the flow of the oil stain, thereby improving the cleaning effect.

And the spraying device 210 is arranged on the side wall 112 of the smoking opening 111 because the rear wall 113 of the smoking opening 111 is opposite to the smoking opening 111, the pollution of oil stain on the rear wall 113 is most serious, and the rear wall 113 is exposed outside. Therefore, the cleaning effect of the rear wall 113 at the side wall 112 of the smoke port 111 can be improved by providing the spraying device 210, and the cleaning liquid flows by its own weight to the inner wall below the smoke port 111 to clean.

Furthermore, the rear wall 113 of the spout 310, which is open toward the flue, cannot be interpreted as having an axis of the opening perpendicular to the rear wall 113, and an angle of 5 ° to 90 ° with the rear wall 113 is still within the scope of the present embodiment, as long as the distance of steam or hot water sprayed toward the rear wall 113 can be shortened.

Referring to fig. 1, in some embodiments, the second cleaning module has a plurality of spraying devices 210, and the plurality of spraying devices 210 are disposed on the sidewall 112 at intervals in a vertical direction.

The second conduit 230 is disposed within the cavity 1121 to reduce the erosion of the second conduit 230 from oil. At the same time, the second pipe 230 is prevented from adhering to the surface thereof, thereby reducing the difficulty of cleaning. In addition, the second pipeline 230 is not arranged in the flue 110, so that resistance of the second pipeline 230 to wind flowing in the flue 110 can be avoided, and the flowing of oil stains is facilitated. And the second duct 230 is provided in the cavity to beautify the appearance of the integrated cooker, so that the integrated cooker looks more concise.

Specifically, as can be seen from the above embodiments, the closer the heating device is to the nozzle 310, the less heat is lost from the hot water, i.e., the shorter the transport distance of the hot water or steam, the less heat is lost. Based on this, the embodiment is provided with two spray pipes 310, two spray pipes 310 are respectively arranged at two sides of the flue 110, two spray pipes 310 can be mutually arranged towards each other, and can also be mutually staggered, and each spray pipe 310 is communicated with the pump body through the first pipeline 320, so that the conveying distance of hot water or steam is shortened, the heat loss is reduced, and the cleaning effect is improved. In addition, it can be understood that the pressure in the pipe gradually decreases along with the heat flow direction in the flowing process of the hot water or the steam, so that the two spray pipes 310 are arranged in the scheme, the conveying distance of the hot water or the steam is shortened, and the phenomenon that the impact force of the steam or the hot water sprayed out of the opening at the tail end of the spray pipe 310 is too small due to insufficient pressure is avoided, so that the spraying range and the impact force of the steam or the hot water are ensured, and the cleaning effect is improved.

In some embodiments, the first delivery device comprises a pump body and a three-way valve, an inlet of the three-way valve being in communication with two nozzles 310, two outlets of the three-way valve being in communication with each other. Specifically, the inlet of the three-way valve is communicated with the pump body, the two outlets are respectively communicated with the two spray pipes 310 through the first pipeline 320, and the three-way valve can control the opening and closing of the two inlets. For example, when the three-way valve alternately opens two outlets, only one nozzle 310 ejects steam or hot water at a time. It will be appreciated that when the single nozzle 310 is operated, the water pressure in the nozzle 310 is high, and the impact force of the sprayed steam is high, so that the cleaning effect can be improved. When the three-way valve controls the two openings to be simultaneously opened, the two spouts 310 can simultaneously spout steam, and the washing speed can be improved. Therefore, the opening and closing states of the three-way valve can be selected according to different oil pollution degrees. For example, when the oil pollution level in the flue 110 is high, the two nozzles 310 can be selected to work alternately to enhance the impact force of steam, thereby improving the cleaning effect. When the oil pollution degree is light, two spray pipes 310 are selected to work simultaneously, so that the cleaning efficiency is improved, and the cleaning time is saved.

An embodiment of a second aspect of the present invention provides a method for controlling an integrated kitchen range according to the embodiment of the first aspect, including:

judging the oil pollution degree of the inner wall of the flue 110;

when the oil pollution degree is mild, the first cleaning module is started, so that the spray pipe 310 sprays hot water or steam;

when the oil pollution degree is moderate, the second cleaning module is started to enable the spraying device 210 to spray the cleaning solution;

when the oil contamination is severe, the second cleaning module and the first cleaning module are activated simultaneously or by colloid, so that the spray pipe 310 sprays steam and the spraying device 210 sprays washing liquid.

Specifically, in the conventional technology, the self-cleaning function of the integrated kitchen mainly depends on steam, adopts a heating mode to enhance the fluidity of the oil stain, and then is matched with the rotation of a fan to separate the oil stain from the machine head 100 of the smoke machine. The steam source is mainly based on a combination of a water pump and a heater, and related heating elements and pipelines are required to be arranged in the structure. The heating mode mainly depends on heating equipment such as an electric heating wire and the like, and is attached to the parts such as a volute or an impeller and the like, so that the purpose of heating greasy dirt is realized. However, in the existing cleaning system, the single physical cleaning mode such as heating or steam has limited cleaning effect on greasy dirt.

The embodiment is provided with a first cleaning module and a second cleaning module, wherein the first cleaning module adopts hot water or steam to physically clean the air inlet flue 110, and the second cleaning module adopts washing liquid to chemically clean. Three cleaning modes are realized through different working states of the first cleaning module and the second cleaning module.

Different cleaning modes are selected according to the pollution degree of the greasy dirt. The first cleaning mode is to start the first cleaning module only when the pollution of the oil stain in the flue 110 is mild, at this time, the nozzle 310 sprays steam or hot water towards the inner wall of the flue 110, and heats the oil stain by using the heat of the steam or hot water to improve the fluidity of the oil stain, and meanwhile, the steam or hot water has a certain impact force on the oil stain to accelerate the separation of the oil stain from the inner wall of the flue 110, thereby accelerating the oil stain to flow to the bottom of the flue 110 and realizing physical cleaning. The second cleaning mode is that when the pollution degree of the oil stain in the flue 110 is moderate, only the second cleaning module is started, the spraying device 210 sprays the cleaning solution, the cleaning solution is used for chemically cleaning the oil stain, the cleaning solution can dissolve the oil stain, the separation of the oil stain and the inner wall of the flue 110 is quickened, and the cleaning effect of the oil stain is improved. The third cleaning mode is to clean the oil stain by using the first cleaning module and the second cleaning module when the oil stain pollution level in the flue 110 is severe, so that the second cleaning module and the first cleaning module are started simultaneously or sequentially when the oil stain pollution level in the flue 110 is severe, so as to perform physical cleaning of steam and chemical cleaning of the cleaning solution on the inner wall of the flue 110, thereby improving the cleaning effect. In the case of heavy oil contamination, the steam is sprayed from the spray pipe 310 because the steam has a higher temperature than the hot water, thereby improving the cleaning effect of the oil contamination in the case of heavy contamination.

The user can select different cleaning modes according to different oil pollution degrees, and compared with a single cleaning mode, the cleaning time and the cleaning cost can be saved while the cleaning requirement is met. For example, in the conventional technology, only the cleaning mode corresponding to the case where the oil pollution is severe in the present embodiment is available, and no matter how much the oil pollution is in the flue 110, only the cleaning liquid and the steam can be used for cleaning at the same time. However, in practice, when the pollution of oil is light, the oil and the water are not required to be cleaned at the same time, so that the resource waste is caused.

It should be noted that, starting the specific situations of the first cleaning module and the second cleaning module simultaneously or sequentially includes: at the same time, nozzle 310 ejects steam and injection device 210 ejects wash liquid. Alternatively, nozzle 310 may be first sprayed with steam or hot water to heat the oil and then sprayed with cleaning solution by spraying device 210. Alternatively, spray device 210 sprays the cleaning solution first to perform chemical dissolution, and spray tube 310 sprays steam or hot water. Alternatively, nozzle 310 and injection apparatus 210 operate alternately.

Referring to fig. 8, fig. 8 is a control flow chart of a control method according to a second aspect of the present invention, and on the basis of the above embodiment, determining the degree of oil pollution in the flue includes:

obtaining the working time of the integrated cooker;

the duration reaches T1, and the pollution degree of the greasy dirt is judged to be mild;

the duration reaches T2, and the pollution degree of the greasy dirt is judged to be moderate;

and the duration reaches T3, and the degree of the greasy dirt pollution is judged to be severe.

Specifically, it can be understood that the longer the working time of the integrated kitchen, the thicker the accumulation of oil stain in the flue 110, and three time thresholds are set according to the accumulation time of oil stain in the flue 110: t1, T2 and T3 correspond to the three cases of light contamination, moderate contamination and heavy contamination, respectively, where T1< T2< T3. For example, the accumulated time length reaches T1, the accumulation of oil stains on the inner wall of the flue 110 is less, the pollution is set to be mild, and the physical cleaning by adopting high-temperature steam or hot water can obtain a better cleaning effect, so that chemical cleaning is not needed, and the cleaning cost is saved. The accumulated time length reaches T2, the oil stain accumulation on the inner wall of the flue 110 is likely to be more, the medium pollution is set, and the chemical cleaning is performed by adopting the cleaning solution. The accumulated time length reaches T3, the oil stain accumulation on the inner wall of the flue 110 is thick, the oil stain is difficult to clean by using steam or washing liquid, and the oil stain is set to be moderately polluted, and the oil stain is thoroughly cleaned by using the mixed cleaning of washing liquefaction and washing steam. Improving the cleaning effect.

It should be noted that, the control method of the embodiment can utilize a common control program in the feedback system, and when the working time of the integrated stove distance from the last cleaning reaches a threshold value, the control program can send out corresponding alarm information to the user, and the user can manually operate through the corresponding button, so that the integrated stove obtains the corresponding control instruction. For example, referring to fig. 8, when the accumulated duration reaches T1, the control program may send a corresponding prompt message, such as an indicator light or an alarm, and after receiving the prompt message, the user may select whether to perform cleaning, and if cleaning is required, perform a corresponding operation, so that the integrated kitchen range obtains a first cleaning control instruction, thereby enabling the integrated kitchen range to start the first cleaning module. If the user chooses not to wash, continuing to carry out the process immediately; after the duration reaches T2, the integrated kitchen range sends out prompt information again to remind whether to wash, if washing is selected, corresponding operation is carried out, so that the integrated kitchen range obtains a second control instruction, and a second washing module is started, if not washing, timing is continued, after the duration reaches T3, the integrated kitchen range sends out prompt information again to remind whether to wash, if washing is selected, corresponding operation is carried out, so that the integrated kitchen range obtains a third control instruction, and the integrated kitchen range simultaneously or alternately starts the first washing module and the second washing module. If not, continuing timing to continuously send prompt information to the user.

In addition, a sensor can be arranged on the inner wall of the flue 110 and used for detecting the thickness of the oil stain and judging the pollution degree of the oil stain according to the thickness of the oil stain.

Referring to fig. 8, in some embodiments, after the spraying is completed, the fan of the integrated oven is started to air dry the flue. To accelerate the drying time of the inner wall of the flue 110 and thereby improve the cleaning efficiency. In addition, the fan can work simultaneously with the first cleaning module and the second cleaning module, namely, the fan is started when the shower is performed, and the downward flow speed of the greasy dirt is accelerated by the wind speed generated by the fan, so that the cleaning efficiency is improved.

In some embodiments, the first delivery device further comprises a pump body and a three-way valve, an inlet of the three-way valve is communicated with the pump body, two outlets of the three-way valve are respectively communicated with the two spray pipes 310, and starting the first cleaning module comprises:

simultaneously opening the inlet and the two outlets of the three-way valve to allow the two spouts 310 to simultaneously spray hot water or steam;

alternatively, the two outlets of the three-way valve are alternately opened to alternately spray steam or hot water through the two spouts 310.

Specifically, when the pollution degree of the oil stain is mild, the oil stain on the inner wall of the flue is less, so that the cleaning efficiency is improved, and the inlet and the two outlets of the three-way valve are simultaneously opened, so that the two spray pipes 310 can spray steam or hot water at the same time, and the inner wall of the flue is fully covered with the steam or hot water. When the pollution degree of the oil stain is severe, the oil stain on the inner wall of the flue is thick, and the two outlets of the three-way valve are alternately opened to improve the cleaning effect. The two spray pipes 310 are made to work alternately, when the single spray pipe 310 works, the air pressure in the spray pipe 310 is larger, the impact force of sprayed steam on the greasy dirt is larger, and the mobility of the greasy dirt is improved, so that the cleaning effect is improved.

In addition, the control method of the integrated kitchen range of the present embodiment may further set more cleaning modes, for example:

when the duration reaches t1, the first cleaning module is started, and two outlets of the three-way valve are simultaneously opened.

When the duration reaches T1, the first cleaning module is started, and two outlets of the three-way valve are alternately opened.

And when the time length reaches T2, starting the second cleaning module.

When the duration reaches t2, the first cleaning module is started, two outlets of the three-way valve are simultaneously opened, and the second cleaning module is started.

When the duration reaches T3, the first cleaning module is started, two outlets of the three-way valve are alternately opened, and the second cleaning module is started.

The control method of the integrated kitchen range of the embodiment has five cleaning modes, further refines the cleaning mode, and according to the pollution degree of the greasy dirt in the flue, the user can have more choices, and when the cleaning effect is achieved, the cleaning time or the cleaning resources are saved, and the control process of the embodiment is similar to the above embodiment and is not repeated here.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present invention.
