When the refrigerating smoke machine is used, when the refrigerating module works, the evaporator in the refrigerating module condenses water in the air into water drops to be attached to the evaporator, and the condensed water is increased along with the operation of the refrigerating smoke machine, so that potential safety hazards exist. When the range hood, the cleaning method and the humidifying method are used, condensed water generated at the evaporator can be atomized and then conveyed into a kitchen chamber to humidify the kitchen chamber, and meanwhile, the condensed water can be conveyed into a volute to clean a suction and discharge fan blade and the volute in the volute, so that the generated condensed water is fully utilized, and the condition that the safe operation of the range hood is influenced due to excessive accumulated condensed water is avoided.
Referring to fig. 1, an embodiment of a range hood 10 includes a cooling assembly 100, and the cooling assembly 100 plays a role of reducing the temperature of the air in the kitchen in the range hood 10. The refrigeration assembly 100 includes an evaporator 110 and a fan 120, wherein the surface temperature of the evaporator 110 is low during refrigeration, and air in the kitchen room enters the kitchen room through the evaporator 110 under the action of the fan 120, so as to reduce the temperature in the kitchen room. Of course, the refrigeration assembly 100 may also include other refrigeration components that are conventional in air conditioning systems, such as a condenser 130 and a throttling element (not shown), among others, for performing a refrigeration function. The fan 120 in this embodiment may be a centrifugal fan.
The range hood 10 includes the water receiving member 200, and when the range hood 10 starts the refrigeration mode, the surface of the evaporator 110 generates condensed water, and the condensed water is received by the water receiving member 200, so as to collect the condensed water. The water receiving member 200 may be a water receiving tank or a container such as a water receiving trough.
It will be appreciated that a corresponding flow-guiding duct (not shown) may be provided between the water receiving member 200 and the evaporator 110, through which flow-guiding duct the condensate water produced along the evaporator 110 is conveyed to the water receiving member 200.
Referring to fig. 1, the range hood 10 further includes an atomizing device 300, the atomizing device 300 is configured to atomize the condensed water in the water receiving member 200, the water receiving member 200 is provided with an atomizing outlet 230, and the atomized condensed water is discharged along the atomizing outlet 230 and then is conveyed to the interior of the kitchen room under the action of the fan 120, so as to humidify the interior of the kitchen room, and further, the condensed water can be consumed, so that the condensed water can be effectively used. The atomizing device 300 may be an ultrasonic atomizer.
Specifically, the cigarette machine assembly 400 further comprises a cigarette machine shell 430, the cigarette machine shell 430 is provided with a cigarette cavity 440 and a gas outlet (not shown) communicated with the cigarette cavity 440, the water receiving part 200 is arranged in the cigarette cavity 440, the atomization outlet 230 is communicated with the gas outlet, the refrigeration assembly 100 is arranged outside the cigarette machine shell 430, atomized condensed water is discharged outside the cigarette machine shell 430 along the atomization outlet 230 and the gas outlet, and the atomized condensed water is conveyed into the kitchen chamber through the evaporator 110 under the action of the fan 120.
Referring to fig. 1, the range hood 10 further includes a smoke exhaust assembly 400, wherein the smoke exhaust assembly 400 sucks smoke in the kitchen and exhausts the smoke to the outside of the kitchen along a smoke pipe, thereby exhausting the smoke in the kitchen. Referring to fig. 1, the cigarette maker assembly 400 includes a volute 410 and a smoking and exhausting blade 420, wherein the smoking and exhausting blade 420 is rotatably disposed inside the volute 410, and when in use, the smoking and exhausting blade 420 is driven to rotate to suck the smoke into the volute 410, and then the smoke is exhausted to the outside of the kitchen through the volute 410 and the smoke pipe.
The assembly 400 may deposit a significant amount of oil stain on the inner walls of the suction fan blade 420 and volute 410 during extended use, thus requiring cleaning of the suction fan blade 420 and volute 410 after a period of use. In order to fully utilize the condensed water, the condensed water in the water receiving member 200 may be conveyed into the volute 410, and the suction fan blade 420 and the volute 410 may be cleaned. Specifically, referring to fig. 1, the spiral case 410 is provided with a condensed water inlet (not shown) for communicating the condensed water outlet with the interior of the spiral case 410, so that when the range hood 10 is used for a long time, the water in the water receiving member 200 can be transported to the interior of the spiral case 410 to clean the air suction vane 420 and the spiral case 410. When the suction fan blade 420 is cleaned, the suction fan blade 420 can rotate at a certain speed, so that each position of the suction fan blade 420 can be cleaned, thus, the condensed water generated at the evaporator 110 can be consumed, the safe use of the range hood 10 is prevented from being influenced by excessive condensed water, and the utilization rate of resources is improved.
It should be noted that the suction fan 420 may be a centrifugal fan.
When the range hood 10 is used, the condensed water dropping along the evaporator 110 may have oil stains or other impurities, and when the condensed water is collected in the water receiving member 200, the atomization effect of the atomization device 300 on the atomization of the condensed water may be affected, and in addition, the atomized condensed water is not clean, and the condensed water is discharged into the kitchen room to further pollute the air in the kitchen room, and similarly, when the condensed water is conveyed into the volute 410, the condensed water may pollute the suction and exhaust fan blade 420 again. Therefore, the condensed water in the water receiving member 200 needs to be purified and reused.
For example, in some embodiments, the range hood 10 further includes a filter 700, the filter 700 is disposed in the water receiving member 200 to divide the interior of the water receiving member 200 into a first water tank 210 and a second water tank 220, the first water tank 210 is used for receiving the condensed water generated by the evaporator 110, the filter 700 is used for filtering the condensed water in the first water tank 210 and then delivering the filtered condensed water to the second water tank 220, the atomization device 300 is used for atomizing the condensed water in the second water tank 220, and the second water tank 220 is provided with an atomization outlet 230 and a condensed water outlet. Through the filtration of the filter member 700, the condensed water transported to the second water tank 220 along the first water tank 210 is cleaner, and thus the air and the suction and exhaust fan blade 420 in the kitchen can be prevented from being polluted.
The filter 700 may be PP (Polypropylene) cotton or a composite of PP cotton and activated carbon.
Referring to fig. 1, the range hood 10 further includes a connecting pipe 500 and a first control valve (not shown), the condensed water inlet is communicated with the condensed water outlet through the connecting pipe 500, and the first control valve is used for controlling the connection and the disconnection of the connecting pipe 500. Alternatively, the first control valve may be a solenoid valve.
Referring to fig. 1, the range hood 10 further includes a controller (not shown), the controller is in communication connection with the atomizing device 300 and the first control valve, and the controller controls the atomizing device 300 and the first control valve to be selectively activated or simultaneously activated according to the operation mode of the range hood 10.
It can be understood that the range hood 10 can operate the suction and exhaust mode independently and simultaneously, or the range hood 10 can operate the cooling mode independently and simultaneously when operating the cooling mode.
When the atomization device 300 and the first control valve are alternatively activated, the range hood 10 operates in the suction and exhaust mode or the refrigeration mode independently, in other words, when the range hood 10 is in use, the cleaning of the volute 410 and the suction and exhaust fan 420 and the humidification of the kitchen room are alternatively performed. Specifically, for example, when it is required to humidify the kitchen separately, the controller controls the atomizing device 300 to start atomizing the condensed water of the water receiving member 200, specifically, the water in the second water tank 220, and at the same time, the controller controls the first control valve to cut off the connecting pipe 500, so that the condensed water cannot be delivered to the scroll 410; conversely, when the suction fan blade 420 needs to be cleaned separately, the controller controls the atomization device 300 to stop operating, controls the first control valve to open the connection pipe 500, so that the condensed water of the water receiving member 200 is delivered into the volute 410, and specifically, the purified water in the second water tank 220 is delivered into the volute 410.
When the controller controls the atomizing device 300 and the first control valve to start simultaneously according to the operation mode of the range hood 10, at this time, the water in the second water tank 220 can be atomized by the atomizing device 300, and meanwhile, the water in the second water tank 220 can be conveyed to the inside of the volute 410 to clean the volute 410 and the suction and exhaust fan blade 420.
Alternatively, the controller may be a single chip or a micro control unit. The communication connection between the controller and the atomizing device 300 and the first control valve may be a direct wire connection between the controller and the atomizing device 300 and the first control valve, or a wireless transmission connection through a wireless network.
Referring to fig. 1, the range hood 10 further includes a second control valve (not shown), the volute 410 is further provided with an oil leakage hole 412 communicating with the interior of the volute 410, and the second control valve is in communication connection with the controller and is used for controlling opening and closing of the oil leakage hole 412.
When the suction and exhaust fan 420 is cleaned, the controller controls the second control valve to close the oil leakage hole 412, and at this time, the condensed water is accumulated in the volute 410 to a certain height reaching the suction and exhaust fan 420, so that the suction and exhaust fan 420 can be cleaned. After the cleaning is finished, the second control valve is controlled by the controller to open the oil leakage hole 412, and the sewage is drained. The second control valve may be a solenoid valve or other valve body capable of controlling the oil leakage hole 412 to open or close.
Referring to fig. 1, the oil leak hole 412 may be located at the lowest position of the scroll case 410, and water or an oil-water mixture in the scroll case 410 may be discharged from the oil leak hole 412.
