The cabinet 11 has a storage chamber 13 at the top for accommodating the detergent box 44, the front of the cabinet 11 has an opening 130 communicating with the storage chamber 13 at a region corresponding to the storage chamber 13, and the detergent box 44 is slidably provided in the storage chamber 13 in such a manner as to enter and exit the opening 130. The user pushes and pulls the detergent box 44, and thus the detergent box 44 is opened or closed, so that the remaining amount of the detergent can be checked conveniently and the detergent can be replenished in time.

The first line 45 can be understood as a feed line for the cleaning medium, which communicates at a first end with the bottom of the water tank 23 and at a second end with the nozzle assembly 30. A fluid supply pump 42 is provided in the first conduit 45 for pumping water from the tank 23 to the nozzle assembly 30 and providing motive force for spraying onto components such as the impeller 122. A first solenoid valve 46 is also provided in the first pipe line 45 for controlling the on/off and flow rate of the first pipe line 45. The first end of the second pipeline 43 is communicated with the bottom of the rear side of the detergent box 44, and the second end is communicated with the portion of the first pipeline 45 between the liquid supply pump 42 and the first solenoid valve 46, so that the detergent in the detergent box 44 can be pumped into the first pipeline 45 through the second pipeline 43 under the suction action of the liquid supply pump 42 and then pumped to the nozzle assembly 30 after being mixed with the water in the first pipeline 45. Of course, the location where the second line 43 connects to the first line 45 may also be upstream of the first solenoid valve 46. The second electromagnetic valve 43 is provided in the second pipe 43, and controls on/off and flow rate of the second pipe 43.

The controller of the integrated kitchen is electrically connected with the liquid supply pump 42, the first electromagnetic valve 46 and the second electromagnetic valve 43, the cleaning device at least has a first working state and a second working state, wherein in the first working state, the first electromagnetic valve 46 and the second electromagnetic valve 43 are both opened, so that the water tank 23 and the detergent box 44 are both communicated with the nozzle assembly 30, therefore, the detergent in the detergent box 44 and the water in the water tank 23 can be pumped by the liquid supply pump 42 and mixed in the pipeline conveying process to form a mixed liquid, the mixed liquid reaches the nozzle assembly 30 and is basically uniformly mixed, and the cleaning requirements of corresponding parts of the oil smoke suction device can be met. In the second operating state, the second solenoid valve 43 is closed, and the first solenoid valve 46 is opened, so that the water tank 23 communicates with the nozzle assembly 30, and in this second operating state, the liquid supply pump 42 only sucks water in the water tank 23 to clean oil stains and residual cleaning agents dissolved on the corresponding parts of the range hood.

In the cleaning process of this embodiment, the above-mentioned first operating condition and second operating condition can be carried out in proper order, that is, when the oil stain needs to be dissolved in the earlier stage, can suck the detergent in the detergent box 44 and spray after the water in the water tank 23 mixes the formation mixed liquid in the pipeline in advance simultaneously, and when the oil stain after dissolving needs to be washed in the later stage, then can directly spray the clear water, from this, can avoid the waste of the detergent because of spraying the detergent that the detergent caused continuously.

The controller typically includes a timing module that times the operating time of the first solenoid valve 46 and the second solenoid valve 43. The controller may control the opening and closing of the first solenoid valve 46 and the second solenoid valve 43 according to the operation time signals of the first solenoid valve 46 and the second solenoid valve 43 transmitted by the timing module, and specifically, the controller may control the cleaning device to switch to the second operating state (only the first solenoid valve 46 is opened) after a set time period is reached after the first operating state (both the first solenoid valve 46 and the second solenoid valve 43 are simultaneously started and closed after the set time period) is finished. The time interval between the first operating state and the second operating state (i.e. the time for standing to dissolve the oil stain) in this embodiment is determined by the amount of the detergent and the amount of the oil stain, and is generally 2-5min. After the mixed liquid of the cleaning agent and the water is sprayed to the part to be cleaned, the mixed liquid is kept stand for a certain time to soften oil stains, then the part is switched to the second working state, clear water is sprayed, softened oil stains on the surface of the corresponding part can be directly washed away, the using amount of the cleaning agent is saved, and the cleaning agent is prevented from being left.

Another important point of the present invention is that an air compensating valve 71 for allowing external air to enter the first pipeline 45 under the suction action of the liquid supply pump 42 is further disposed in the first pipeline 45, the air compensating valve 71 includes an air compensating valve body 711 and an air compensating valve cover 712, the air compensating valve body 711 has two connecting ports for connecting with the first pipeline 45 and one air compensating port, the air compensating valve cover 712 is connected to the air compensating port, the air compensating valve cover 712 has an air compensating port 7120, the inner diameter of the air compensating port 7120 is smaller than the minimum inner diameter of the pipeline, and the inner diameter of the air compensating port 7120 is generally 0.5-2mm. The air supplement valve cover 712 and the air supplement valve body 711 can be connected by gluing, hot melting, screwing and the like. The air supply valve 71 supplies air to the pipeline, so that the aim of saving water is fulfilled, and the waste of cleaning agents and water is avoided. On the other hand, after air is supplied in the pipeline, the cavitation effect of the nozzle assembly is enhanced, the spraying effect is better, and particularly, the premixing effect of water and a cleaning agent in the pipeline is improved.

The first pipeline 45 is further provided with a premixing section 61 for turbulent flow of the mixed liquid of the cleaning agent and the water, the premixing section 61 comprises premixing cavities 60 with the caliber increasing first and then decreasing along the fluid flowing direction, and at least two premixing cavities 60 are sequentially arranged at intervals along the fluid flowing direction, as shown in fig. 6, 3 premixing cavities 60 are arranged. During the process of the mixed liquid of detergent and water flowing through the premixing chamber 60, the turbulence degree increases due to the change of pipe diameter, and the mixing effect of detergent and water is increased, as shown in fig. 7 and 8.

When the cleaning device is in the first working state and the second working state, the air compensating valve 71 can be in the opening state, thereby achieving the purpose of saving water.

The first operating state and the second operating state may be cyclically executed for a plurality of cycles, and may be specifically implemented by a control parameter input by a user. After the last cleaning cycle is finished, specifically after the second working state of the cleaning device is finished, the main motor 123 of the fan system 12 drives the impeller 122 to operate at a set rotating speed, so as to throw off water and oil stains on the impeller 122, thereby realizing rapid air drying of the cleaning component.
