A great deal of oil smoke and heat are generated in the cooking process, which is almost a problem facing every family. Especially in hot and dry spring seasons, the heat generated by cooking causes the temperature in the kitchen to rise rapidly. In order to solve the problem of oil smoke, the oil smoke generated by the range hood is generally exhausted to the outdoor, so that the pollution of the oil smoke to the indoor environment is reduced, and the indoor air quality is improved, so that the range hood is basically one of essential appliances in a kitchen. The range hood can work to form a negative pressure state indoors, and the problems of difficulty in opening doors and windows, air leakage in gaps between the doors and the windows and high noise can be caused under the negative pressure state. Aiming at the problems of negative pressure and temperature rise in a kitchen caused by cooking or working of a smoke exhaust ventilator, the existing solution is to install an air conditioner and the smoke exhaust ventilator in the kitchen at the same time, adjust the indoor temperature by using the air conditioner and remove indoor oil smoke by using the smoke exhaust ventilator.

the control method comprises the following steps:
under the condition that the range hood module is in an operating state, acquiring indoor temperature corresponding to indoor environment;
calculating a difference value between the indoor temperature and an indoor target temperature;
comparing the difference value with a preset temperature difference threshold value;
and controlling the circulation states of the air flows in the first air channel and the second air channel and controlling the running state of the fresh air conditioning module according to the comparison result.
The oil smoke air-conditioning all-in-one machine is provided with the second air channel, and partial sections of the second air channel and partial sections of the oil smoke channel are arranged in a heat exchange mode, so that whether the indoor temperature needs to be adjusted by recovering heat in oil smoke can be judged according to the difference value between the indoor temperature and the indoor target temperature in the operation process of the all-in-one machine, the recovered waste heat is fully utilized to ensure that the indoor temperature is stabilized within a certain temperature range, and the energy consumption of the whole all-in-one machine can be reduced while the indoor temperature is ensured to be comfortable.

The operating parameter of the compressor may be the compressor frequency, the direction of intake and exhaust, etc.
As for the control method of the above-mentioned lampblack air-conditioning all-in-one machine, in a feasible implementation manner, the step of "the preset temperature difference threshold includes a first preset temperature difference threshold," controlling the flow states of the airflows in the first air duct and the second air duct according to the comparison result, and controlling the operation state of the fresh air-conditioning module "specifically includes:
if the difference is lower than the first preset temperature difference threshold value, then: enabling the first air duct to be in a circulation state; enabling the second air duct to be in a non-circulation state; the compressor is not operated.
When the range hood module operates, a negative pressure state is easily formed indoors, fresh air circulates in the first air channel by communicating the first air channel and opening the outdoor fresh air inlet, and the indoor and outdoor air pressure balance can be maintained; and because the difference between the indoor temperature and the target temperature is smaller, the waste heat in the oil smoke does not need to be recovered, and the compressor is not operated to intentionally adjust the indoor temperature to the target temperature, because the temperature which is comfortable for human bodies is a range, and the temperature change is not large in the temperature range, the operation can purify the indoor air, reduce the energy consumption of the whole integrated machine and avoid the unnecessary waste of energy.
It should be noted that, there are two situations when the difference value is lower than the first preset temperature difference threshold value: indoor temperature is higher than indoor target temperature and the difference of the two is less than first preset difference in temperature threshold value to and indoor target temperature is higher than indoor temperature and the difference of the two is less than first preset difference in temperature threshold value, no matter which kind of situation, because the difference is not big between the two, the difference in temperature of outdoor temperature and indoor temperature usually this moment is also very little, therefore the new trend gets into indoor also very little to indoor temperature's influence. In addition, the first predetermined temperature difference threshold value may be determined experimentally.
As for the control method of the above-mentioned lampblack air-conditioning all-in-one machine, in a feasible implementation manner, the step of setting the temperature difference threshold value to further include a second temperature difference threshold value, "controlling the flow states of the air flows in the first air duct and the second air duct according to the comparison result, and controlling the operation state of the fresh air-conditioning module" specifically includes:
if the difference value is not lower than the first preset temperature difference threshold value and lower than the second preset temperature difference threshold value, then: enabling the first air duct to be in a non-circulation state; enabling the second air duct to be in a circulation state; the compressor is not operated.
The difference between the indoor temperature and the indoor target temperature is not lower than a first preset temperature difference threshold value and is lower than a second preset temperature difference threshold value, and the two situations are as follows: the indoor target temperature is higher than the indoor temperature and the difference value of the indoor target temperature and the indoor target temperature is between a first preset temperature difference threshold value and a second preset temperature difference threshold value, and the indoor temperature is higher than the indoor target temperature and the difference value of the indoor temperature and the target temperature is between the first preset temperature difference threshold and the second preset temperature difference threshold, in any case, the difference value between the indoor temperature and the target temperature is certain, however, in this case, the outdoor temperature is still lower than the indoor temperature, even lower than the target temperature, and if the outdoor fresh air is directly input into the room, the indoor temperature will suddenly change, the second air channel is communicated to enable the fresh air to exchange heat with the oil smoke channel without starting the compressor for heating, thus, the oil smoke is exhausted, meanwhile, the indoor temperature can be maintained in a comfortable range by utilizing the recovered waste heat, and the heating mode of the integrated machine is avoided being started, so that the energy consumption of the operation of the integrated machine can be reduced.
In a feasible implementation manner, the step of "controlling the flow states of the airflows in the first air duct and the second air duct and controlling the operation state of the fresh air conditioning module according to the comparison result" specifically includes:
if the difference is not lower than the second preset temperature difference threshold value, then: enabling the first air duct to be in a circulation state; enabling the second air duct to be in a non-circulation state; and operating the compressor and enabling the fresh air conditioning module to operate in a refrigeration mode.
If the difference value is higher than the second preset temperature difference threshold value, the indoor temperature is far higher than the target temperature, under the condition, the outdoor temperature is also far higher than the target temperature, the first air channel is in a circulation state, the fresh air conditioning module is enabled to refrigerate, the indoor and outdoor air pressure balance can be maintained, and the indoor temperature can be guaranteed to be in a comfortable temperature range. The second predetermined temperature difference threshold is determined experimentally.

Meanwhile, the first fan 25 in the right air duct is reversed to exist as a second fan in the second air duct. When the second fan is operated, outdoor fresh air can flow through the total heat exchange core 14 in the process of being directly conveyed to the indoor environment through the second air duct, and fresh air flow in the total heat exchange core 14 can exchange heat with oil fume flow.
It can be understood that if fresh air enters from the right outdoor fresh air inlet 20 and exits from the left indoor air inlet/outlet 22, the effect is the same as that in the previous embodiment, and the operation of each component can be adjusted adaptively.
The oil smoke and air conditioner all-in-one machine in the embodiment of the invention is also provided with a total heat exchange core 14, the total heat exchange core 14 comprises a first flow passage and a second flow passage which are arranged in a cross way and in physical contact with each other and can realize heat exchange, the first flow passage is arranged or formed in a second air passage, and the second flow passage is arranged or formed in an oil smoke passage 13 so as to absorb waste heat in oil smoke in the processes of oil smoke exhaust and fresh air exchange.
It should be noted that the fresh air conditioning module 2 in the above embodiment has a dual-module structure, and the second air duct can be constructed by controlling the position of the first air door 23 and the direction of rotation of the first fan 25, and this arrangement mode has a simple structure, a high component utilization rate, and a high efficiency. It will be understood by those skilled in the art that the second air duct may also be configured as an independent structure, that is, a separate air duct, an outdoor fresh air inlet 20, and an indoor fresh air outlet are configured, a second motor different from the first motor on the right side is configured in the air duct, a partial section of the second air duct and a partial section of the smoke channel 13 can exchange heat with each other, and so on.
Based on the oil smoke air conditioner all-in-one machine, the control method comprises the following steps:
and S10, acquiring the indoor temperature corresponding to the indoor environment under the condition that the range hood module 1 is in the running state.
Specifically, the operation of the range hood module 1 needs to satisfy a certain condition, and whether the indoor oil smoke concentration exceeds the preset oil smoke concentration is judged according to the judgment, and the indoor oil smoke concentration is specifically determined by an oil smoke concentration sensor 10 arranged at an inlet of an oil smoke channel 13. If the measured oil smoke concentration is not lower than the preset oil smoke concentration threshold value, the range hood module 1 needs to be operated; if the oil smoke concentration that surveys is less than preset oil smoke concentration threshold value, then need not operate lampblack absorber module 1, only need according to indoor circumstances judge whether need operate fresh air conditioning module 2 can, if need operate fresh air conditioning module 2, then this module only uses as the air conditioner, corresponding operation logic is prior art, does not describe in detail here again. The indoor temperature corresponding to the indoor environment is measured by an indoor temperature sensor 27 provided at the first indoor air outlet 29 or at another position.
And S20, calculating the difference between the indoor temperature and the indoor target temperature. The target temperature is the temperature set by the user, and the setting mode can be realized by a remote controller, a touch panel and the like.
And S30, comparing the difference value with a preset temperature difference threshold value.
Specifically, the preset temperature difference threshold comprises a first preset temperature difference threshold and a second preset temperature difference threshold, the first preset temperature difference threshold is lower than the second preset temperature difference threshold, and the specific numerical value is obtained in the experimental stage. For example, the first preset temperature difference threshold is 3 ℃ and the second preset temperature difference threshold is 6 ℃. It is to be understood that the above values representing temperatures are merely exemplary, and that specific temperature values may be determined experimentally based on a number of factors, such as location, climate conditions, and the like.
And S40, controlling the circulation state of the air flow in the first air duct 26 and the second air duct and controlling the running state of the fresh air conditioning module 2 according to the comparison result.
Specifically, the operation state of the fresh air conditioning module 2 is mainly controlled by the operation parameters of the compressor, which include the frequency, the pressure and the direction of air intake and exhaust, and the like of the compressor.
Specific comparison results include the following cases:
(1) the difference is lower than a first preset temperature difference threshold.
If the comparison result is that the difference value is lower than the first preset temperature difference threshold value, it indicates that the all-in-one machine only needs to suck fresh air to maintain indoor and outdoor air pressure balance, and does not need to adjust the indoor temperature, and the corresponding control logic of the all-in-one machine refers to the figure 1: placing the first air chute 26 in flow communication; enabling the second air duct to be in a non-circulation state; the compressor is not operated. Specifically, the first air door 23 is controlled to swing to the position Q, so that the outdoor fresh air inlets 20 on the two sides are opened, and the indoor air inlet and outlet 22 are closed; swinging the second damper 28 to open the first indoor air outlet 29, thereby connecting the first air duct 26; opening the first fan 25 to make the air in the first air duct 26 in a circulating state, and conveying the fresh air to the indoor environment through the first air duct 26; accordingly, the second air duct is in a non-circulation state at this time, the compressor is not operated, and the first air duct 26 exists only as a fresh air duct. The fresh air is purified after passing through the air filter 21 before entering the first air duct 26. When the two modules work cooperatively, fresh air input into the room is used for supplementing air lost due to oil smoke discharge so as to maintain air pressure balance; the oil smoke is discharged after being filtered by the first oil smoke filter screen 11 and the second oil smoke filter screen 15, negative pressure is generated at the inlet of the oil smoke channel 13 due to the circulation of the oil smoke, more input fresh air directly enters the oil smoke channel 13 under the action of the negative pressure, and vortex is formed around the inlet of the oil smoke channel 13, so that the oil smoke is effectively prevented from floating.
(2) The difference value is between the first preset temperature difference threshold value and the second preset temperature difference threshold value.
If the difference value is between the first preset temperature difference threshold value and the second preset temperature difference threshold value, it indicates that a certain temperature difference exists between the indoor temperature and the target temperature, and if fresh air is directly introduced, the indoor temperature can be obviously reduced by the low-temperature fresh air, and the corresponding control logic under the situation refers to fig. 2: placing the first air chute 26 in a non-flow state; enabling the second air duct to be in a circulation state; the compressor is not operated. Specifically, the first air door 23 on the left side is controlled to swing to the position Q, so that the outdoor fresh air inlet 20 on the left side is opened, and the indoor air inlet and outlet 22 is closed; controlling the first air door 23 on the right side to swing to the position P, so that the outdoor fresh air inlet 20 on the right side is closed, and the indoor air inlet and outlet 22 on the right side is opened; the second air door 28 is controlled to swing to close the first indoor air outlets 29 on the two sides; the first fan 25 on the left side is not turned on to put the first air duct 26 in a non-circulation state; the first fan 25 on the right side is opened, so that fresh air is exhausted to the indoor environment from the indoor air inlet and outlet 22 on the right side after passing through the outdoor fresh air inlet 20 on the left side, part of the first air duct 26, the total heat exchange core 14 and part of the first air duct 26 on the right side, and the second air duct is in a circulation state. The compressor is not started in the process, the temperature of the fresh air is only improved by utilizing the heat exchange between the oil smoke channel 13 and the fresh air, and the large influence of the low-temperature fresh air on the indoor temperature is avoided.
(3) The difference is higher than a second preset temperature difference threshold.
If the comparison result shows that the difference value is not lower than the second preset temperature difference threshold value, the indoor temperature is higher than the target temperature, and the indoor temperature needs to be cooled by means of an air conditioner. The corresponding control logic in this case is shown in fig. 1, and is different from the case (1), in the case (3), the compressor is started and operated in the refrigeration mode while fresh air is sucked, so that the sucked fresh air is cooled, and the integrated machine is operated in the fresh air refrigeration-oil fume exhaust mode.
Referring to fig. 3, if the range hood module 1 does not need to be operated and only the indoor temperature needs to be reduced, the all-in-one machine is controlled to operate in the cooling mode as shown in fig. 3. Specifically, the first air doors 23 on both sides are controlled to swing to the position P, so that the outdoor fresh air inlets 20 on both sides are closed, and the indoor air inlets and outlets 22 are opened; swinging the second damper 28 to open the first indoor air outlet 29, thereby connecting the first air duct 26; the first fan 25 is turned on to make the air in the first air duct 26 in a circulating state, the compressor is turned on to cool, and the indoor return air is cooled by the evaporator 24 and then is input into the room to reduce the indoor temperature.
It can be understood that the fresh air conditioning module 2 in this embodiment is described by taking a dual module as an example, and of course, the fresh air conditioning module 2 may also have a single structure, or only one of the fresh air conditioning modules 2 may be operated during the operation, and so on.
It should be noted that the operating speed of the third fan 12 in the range hood module 1 is related to the oil smoke concentration, the oil smoke concentration can be divided into a plurality of levels, each level corresponds to a corresponding third fan 12 rotating speed, so that different fan rotating speeds can be selected according to the oil smoke concentration, and thus, the overall energy consumption of the integrated machine can be reduced while the oil smoke exhaust effect is ensured.
