s100: when the range hood 100 is in the running state, judging the state of the condenser 320;

specifically, when a user cooks in a kitchen, the range hood 100 is turned on, and when the range hood 100 is turned on and is in an operating state, it is determined whether the condenser 320 needs to be cleaned.

S300: when the state of the condenser 320 is a state needing cleaning, the cleaning agent storage tank 410 is controlled to add the cleaning agent into the spraying liquid storage tank 420, and the spraying liquid formed by mixing the cleaning agent and the cleaning liquid in the spraying liquid storage tank 420 is supplied to the spraying assembly 430;

specifically, when the refrigeration assembly 300 is in operation, the drainage port 442 of the condensate recovery tank 440 is closed, the condensate recovery tank 400 recovers the condensate generated by the evaporator 340, and when the condenser 320 needs to be cleaned, the water in the condensate recovery tank 440 can be delivered into the spray storage tank 420 as a cleaning solution by turning on the water pump 450 or turning on the water supply valve, or the external water can be delivered into the spray storage tank 420 as a cleaning solution by controlling the external water source; the cleaning agent control valve 411 is opened, a predetermined amount of the cleaning agent stored in the cleaning agent storage tank 410 is added to the spray liquid storage tank 420, so that the cleaning agent and the cleaning agent are mixed in the cleaning agent storage tank 410, and then the mixed spray liquid is delivered to the spray assembly 430.

When the condenser 320 is cleaned by using the condensed water generated by the evaporator 340, after the condenser 320 is judged to be in a state that the condenser is required to be cleaned, the amount of water stored in the condensed water recovery tank 440 can be obtained by the liquid level detection device 441, and when the amount of water in the condensed water recovery tank 440 is insufficient, the condensed water can be supplemented by the water supplementing pipe 520 or by starting the refrigeration system to generate the condensed water.

S400: the spray assembly 430 is controlled to spray a spray toward the condenser 320 to clean the condenser 320.

The spraying assembly 430 adopts a high-pressure nozzle, and the spraying liquid formed by mixing the cleaning agent and the cleaning liquid is sprayed out to the condenser 320 through high pressure, so that the cleaning effect is better.

In the scheme of the embodiment, the condenser 320 is arranged in the main flue 210, and the heat of the condenser 320 is taken away by using the air generated when the fan in the range hood 100 sucks the oil smoke, so that the total amount of the exhaust air exhausted to the outside when the range hood 100 and the condenser 320 are independently arranged indoors can be reduced, heat leakage caused by the exhaust air is reduced, the indoor refrigeration effect is improved, the fan does not need to be independently arranged for the condenser 320 to provide hot air exchange, and the installation cost and the use cost are both lower; in addition, the arranged spraying assembly 430 can clean the condenser 320, so that the problem of low heat exchange efficiency caused by oil stains attached to the condenser 320 is avoided, and the indoor refrigeration effect can be improved; before the condenser 320 is cleaned, the cleaning agent stored in the cleaning agent storage box 410 flows into the spraying liquid storage box 420, and the cleaning agent and the cleaning liquid are mixed by utilizing the space in the spraying liquid storage box 420 and then sprayed out by the spraying component 430, so that the cleaning agent is mixed more fully and uniformly, the cleaning effect on the condenser 320 is improved, the heat exchange efficiency of the cleaned condenser 320 is ensured, and the using amount of the cleaning agent can be saved; meanwhile, the condenser 320 is arranged in the main flue 210, so that a complex process of perforating on a wall is omitted, the installation space is saved, outdoor hot air can be prevented from entering indoor or flowing out through the perforations on the wall surface of the indoor cold air through hole through the perforations on the wall surface, and the indoor refrigeration effect is better.

As a further aspect of the above embodiment, before step S400, the method further comprises the steps of:

s200: controlling the range hood 100 to stop;

after the range hood 100 is stopped, step S400 is performed again.

Step S200 may also be performed before step S300, and after the range hood 100 is stopped, step S300 and step S400 are sequentially performed.

Specifically, when the condenser 320 is judged to be in the state needing to be cleaned, a prompt of 'needing to clean the condenser 320' can be sent to a user, the smoke ventilator 100 is controlled to be actively operated after being stopped, and the steps are started to execute subsequent steps such as S400 and the like; the user may not be prompted to "need to clean the condenser 320", and the following steps such as step S400 and the like may be automatically executed after the range hood 100 is controlled to stop by setting the program.

When a user turns on the range hood 100 to cook in a kitchen, whether the condenser 320 needs to be cleaned is judged, after the condenser 320 is judged to be in a state needing to be cleaned, the user is still in the cooking state, at the moment, a prompt of 'needing to clean the condenser 320' is sent to the user in modes of a display screen, an alarm lamp, voice or sending information to a mobile phone of the user, and the like, the user finishes cooking, and after the range hood 100 is turned off, the user automatically or actively operates the range hood to start cleaning the condenser 320.

In the further scheme of the above embodiment, when the range hood 100 is turned on, a user mostly cooks in a kitchen, and if the condenser 320 is cleaned in the state that the range hood 100 is turned on, the sprayed spraying liquid increases the wind resistance in the main flue 210 when the condenser 320 is cleaned, so that the wind volume is reduced, and the performance of the range hood 100 is affected; after the user finishes cooking and closes the range hood 100, the cleaning work of the condenser 320 is carried out, so that the cleaning work of the condenser 320 can be carried out after the current cooking is finished, and the current cooking is not influenced; in addition, in winter, the amount of the recovered condensed water is small, the refrigeration assembly 300 may need to be started to replenish the condensed water in the process of cleaning the condenser 320, the temperature in the kitchen is further reduced at this time, discomfort is caused to people in the kitchen, and after cooking is finished and the range hood 100 is closed, the condenser 320 is cleaned, so that discomfort caused to the cooking people can be avoided.

As a further aspect of the above embodiment, after step S400, the method further comprises the steps of:

s500: a sewage discharge port 461 of the sewage recovery tank 460 below the condenser 320 is opened to discharge the sewage recovered in the sewage recovery tank 460 into a sewage discharge system;

of course, in step S400, the drain 461 of the wastewater recycling tank 460 can be kept open, and wastewater can be discharged through the drain 461 during the process of cleaning the condenser 320.

S600: the range hood 100 is controlled to be turned on to air-dry the condenser 320.

Specifically, after step S400 or S500 is executed, the range hood 100 may be automatically turned on, or the user may actively turn on the range hood 100 after sending a "cleaning completion" prompt to the user, and after the range hood 100 runs for a preset time, the range hood 100 may be automatically turned off by program control, or the user may actively turn off the range hood 100.

In a further aspect of the above embodiment, the water content in the main flue 210 is reduced, the spraying liquid is prevented from adhering to the surface of the condenser 320 and the main flue 210 to cause corrosion, and the like, and the service lives of the condenser 320 and the main flue 210 can be prolonged.

As a further aspect of the above embodiment, step S100 includes:

s110: when the range hood 100 is in the running state, judging the working state of the refrigeration assembly 300;

s120: when the working state of the refrigeration assembly 300 is the running state, acquiring the condensation temperature and the refrigerant outlet temperature of the condenser 320;

specifically, the condensation temperature is a temperature at which the refrigerant changes phase in the condenser 320, and may be obtained by a first temperature sensor provided in the middle of the refrigerant flow path in the condenser 320.

The refrigerant outlet temperature is a temperature of the heat-exchanged refrigerant reserved in the condenser 320, and may be obtained by a second temperature sensor disposed at the refrigerant outlet of the condenser 320.

S130: calculating the temperature difference between the condensation temperature and the refrigerant outlet temperature;

after the condensing temperature and the refrigerant outlet temperature are obtained, the control processor calculates a temperature difference.

S140: when the temperature difference is smaller than the first preset value, the state of the condenser 320 is judged to be a state needing cleaning;

s150: when the temperature difference is greater than or equal to the first preset value, the state of the condenser 320 is judged to be a cleaning-free state.

When the condenser 320 is in a cleaning-free state, the range hood 100 and the refrigeration assembly 300 work normally, and parts such as the spray assembly 430 for cleaning the condenser 320 do not need to operate.

In the further scheme of the above embodiment, whether the condenser 320 needs to be cleaned is determined by the difference between the condensing temperature and the refrigerant outlet temperature, so that the adhesion condition of the oil stains on the surface of the condenser 320 can be rapidly and accurately grasped. When the temperature difference is greater than or equal to the first preset value, the oil stain of the condenser 320 is attached within an acceptable range, and the condenser 320 does not need to be cleaned; when the temperature difference is smaller than the first preset value, it indicates that the condenser 320 has poor heat exchange due to dirt attached to the surface of the condenser 320, and the condenser 320 needs to be cleaned.

As shown in fig. 4, when the kitchen air conditioner is used in a kitchen air conditioner without the bypass flue 220, the step S100 includes:

s160: when the range hood 100 is in an operating state, acquiring the accumulated operating time of the range hood 100 after the condenser 320 is cleaned for the last time;

acquiring the accumulated operation time after the range hood 100 finishes cleaning the condenser 320 last time can be executed after step 110 is executed, when the working state of the refrigeration assembly 300 is a shutdown state; the operation state of the refrigeration assembly 300 may not be determined, and the step S160 of obtaining the accumulated operation time after the range hood 100 has been cleaned from the previous time to the condenser 320 is directly performed;

s171: when the accumulated running time is greater than a second preset value, judging that the state of the condenser 320 is a state needing to be cleaned;

s172: when the accumulated operation time is less than or equal to the second preset value, the state of the condenser 320 is judged as a cleaning-unnecessary state.

After step S600, the accumulated operating time is cleared.

When the bypass flue 220 is not provided, no matter whether the refrigeration assembly 300 works or not, the lampblack sucked in by the range hood 100 needs to be discharged outdoors through the installation cavity 211 provided with the condenser 320, and oil stains are attached to the surface of the condenser 320 in the operation process of the range hood 100. In the further scheme of the embodiment, the condenser 320 can be cleaned regularly when the range hood 100 does not need to be refrigerated in operation in winter and the like, so that the cleanness of the surface of the condenser 320 is ensured.

As shown in fig. 5, when used in a kitchen air conditioning apparatus provided with a bypass flue 220, step S100 includes, as a further aspect of the above embodiment:
