In addition, if "and/or" and/or "are used throughout, the meaning includes three parallel schemes, for example," a and/or B "including a scheme, or B scheme, or a scheme where a and B are satisfied simultaneously. In addition, the technical solutions of the embodiments may be combined with each other, but it is necessary to base that the technical solutions can be realized by those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent and not within the scope of protection claimed in the present invention.
The invention provides a range hood.
Referring to fig. 1 to 5, in an embodiment of the present invention, the range hood includes:
a tobacco machine main body 1;
an air purifying device 2 provided in the main body 1 and having a purifying air duct and an air outlet 202 communicating with the purifying air duct;
the temperature acquisition device 4 is used for acquiring the environment temperature of the range hood; and
and the controller 3 is electrically connected with the temperature acquisition device 4 and is used for controlling the air output of the air purification device 2 according to the ambient temperature.
It can be understood that the smoke exhaust duct is arranged in the smoke exhaust main body 1, and a smoke inlet of the smoke exhaust duct is communicated with the indoor space and is generally suspended above a kitchen range so as to be convenient for sucking the smoke into the smoke exhaust duct; the smoke outlet of the oil smoke suction air duct is communicated with the outside of the room to discharge the oil smoke to the outside of the room; of course, the fume exhaust duct is internally provided with a fume exhaust fan for enabling air flow to flow from the fume inlet to the fume outlet. It will be appreciated that the range hood body 1 has the function of a conventional range hood.
For the air purification device 2, the purification air channel and the oil fume suction air channel are mutually independent, of course, an air inlet 201 communicated with the purification air channel is further arranged, and a filter element 22 is arranged in the purification air channel. The air purifying device 2 further has a purifying fan 21 for driving the air in the purifying duct to flow toward the air outlet 202. The air inlet 201 and the air outlet 202 are both communicated with the indoor space, the air inlet 201 is used for sucking air in the kitchen, the filter 22 is used for filtering and purifying the sucked air, and the air outlet 202 is used for discharging the filtered and purified air back into the kitchen.
When the air purification device 2 and the range hood main body 1 work cooperatively, most of the oil smoke generated in the cooking process is discharged outdoors through the oil smoke suction duct, a small part of the oil smoke can escape to other spaces in a kitchen, and the small part of the oil smoke can be further removed through the purification duct of the air purification device 2, so that the pollution of the oil smoke to the air environment and the damage to the health of a human body are further reduced.
In addition, the technical scheme of the invention can also obtain the environmental temperature of the range hood through the temperature obtaining device 4, and the air outlet volume of the air purifying device 2 is adjustable, so that it can be understood that the air outlet volume of the air purifying device 2 acts on a user, and the user has different air outlet volume demands on the air purifying device 2 under different environmental temperatures, and thus, the air outlet volume of the air purifying device 2 is controlled through the controller 3 according to the environmental temperature, so that the air outlet volume can meet the demands of the user under the corresponding environmental temperature, and the body feeling of the user is more comfortable.
Alternatively, the main body 1 of the cigarette machine and the air purifying device 2 can share one controller 3, and the controller 3 is usually fixed on the main body 1 of the cigarette machine; it will be appreciated that the range body 1 is generally larger in size than the air cleaning device 2, with more and more convenient locations and space for mounting the controller 3. The controller 3 is typically connected in communication with the air cleaning device 2 by wired means; of course, the controller 3 may also be connected in communication with the air cleaning device 2 by wireless means. However, the present design is not limited thereto, and in other embodiments, an independent controller 3 may be provided corresponding to the main body 1 of the smoke machine, and another independent controller 3 may be provided corresponding to the air purifying device 2, so that the controller 3 for controlling the air purifying device 2 is mounted on the air purifying device 2.
Further, in the process that the controller 3 controls the air output of the air cleaning device 2 according to the environmental temperature, when the environmental temperature increases, the controller 3 controls the air output of the air cleaning device 2 to increase.
It will be appreciated that during cooking, the ambient temperature to which the range hood is exposed typically increases. In particular, in summer, the increase in the ambient temperature causes discomfort to the user due to overheating, and at this time, the increase in the air output of the air-purifying device 2 causes the user to feel cooler and feel more comfortable.
However, in other embodiments, when the air purifying device 2 is further provided with an electric auxiliary heating device to enable the air to be exhausted, for winter, the ambient temperature will be very small at the beginning of cooking, at this time, the user needs the air purifying device 2 to provide a relatively large amount of warm air, and as the cooking activity proceeds, the ambient temperature will be continuously increased, so that the user's demand for warm air is reduced, at this time, the controller 3 can control the air exhaust of the air purifying device 2 to be reduced, so as to save energy.
Further, the rotation speed of the purge fan 21 is adjustable, and it is understood that the larger the rotation speed of the purge fan 21 is, the larger the air volume it can generate. Therefore, the controller 3 can increase the air output of the air cleaning device 2 by controlling the rotational speed of the cleaning fan 21 to increase. In particular, an increase in the rotational speed of the purge fan 21 can not only increase the air output but also increase the air output speed of the air cleaner 2, thereby enabling the user to experience a cooler feeling.
However, the present design is not limited thereto, and in other embodiments, when the purifying fans 21 are provided in plural, the controller 3 may further increase the air output of the air purifying device 2 by controlling the starting number of the purifying fans 21 to increase; it will be appreciated that, regardless of whether the plurality of purifying fans 21 are arranged side by side or are sequentially arranged in the extending direction of the purifying air duct, the larger the number of the purifying fans 21 is started, the larger the air quantity generated by the purifying fans can be; of course, the way in which the air output is changed by adjusting the rotation speed of the purifying fan 21 can enable the change of the air output to be relatively continuously adjustable.
In addition, in other embodiments, a plurality of purifying fans 21 with adjustable rotation speed may be disposed in the purifying air duct, and the controller 3 changes the air output of the air purifying device 2 by changing the number of the activated purifying fans 21 and the rotation speed of the purifying fans 21 at the same time.
Further, the air purification device 2 has a plurality of air volume steps (it is understood that the air volume corresponding to different air volume steps is different), and different air volume steps correspond to different temperature ranges. In the process that the controller 3 controls the air output of the air purification device 2 according to the ambient temperature, the controller 3 firstly determines a temperature interval in which the ambient temperature is located, and then controls the air purification device 2 to output air in a corresponding air quantity gear; thus, the number of times of change of the air output of the air purifying device 2 can be reduced, and the control process of the air output of the air purifying device 2 is simpler. Optionally, different air volume gears correspond to different rotation speeds of the purifying fan 21; or, different air quantity gears correspond to different starting numbers of the purifying fans 21. Of course, the air volume gear corresponding to the higher temperature interval corresponds to a larger rotational speed of the purge fan 21, or a larger number of purge fans 21 are started.
In one embodiment, when the ambient temperature is within a temperature range of [24 ℃,28 ℃), the corresponding air volume gear is a first gear, and the first gear air volume is 0.5 times of the maximum air volume; when the ambient temperature is within a temperature range of [28 ℃ and 30 ℃), the corresponding air quantity gear is the second gear, and the second gear air quantity is 0.8 times of the maximum air quantity; when the ambient temperature is within the temperature range [30 ℃ and + ] infinity, the corresponding air volume gear is the third gear, and the third gear air volume is the maximum air volume.
In addition, it should be noted that, when the air purification device 2 is turned on, the controller 3 controls the air purification device 2 to perform air outlet with a preset air outlet volume, then obtains the ambient temperature, and controls the air purification device 2 to perform air outlet with a corresponding air outlet gear according to a temperature interval in which the ambient temperature is located; or when the air purifier is started, the ambient temperature can be directly obtained, and the air purifier 2 can be controlled to output air in a corresponding air quantity gear according to the temperature interval where the ambient temperature is located. For the former mode, the preset air output is generally set to be the maximum air output of the air purification device 2; of course, in some other embodiments, the preset air output may also be set as the minimum air output of the air purifying device 2.
Further, the temperature acquiring device 4 comprises a temperature sensor 41 arranged on the range hood and electrically connected with the controller 3, and the controller 3 acquires the ambient temperature through the temperature sensor 41; that is, the range hood itself has a function of acquiring the ambient temperature, and thus, even when a network signal is absent, the controller 3 can immediately acquire the ambient temperature, thereby controlling the air outlet amount of the air cleaning device 2 according to the ambient temperature. Optionally, the temperature sensor 41 is disposed on the main body of the cigarette machine, and the main body 1 of the cigarette machine is generally larger than the air purifying device 2, so that the position and the space for installing the temperature sensor 41 are more convenient; of course, in other embodiments, the temperature sensor 41 may also be provided in the air purifying device 2.
However, the present design is not limited thereto, and in other embodiments, the temperature obtaining device 4 may further include a communication receiver disposed on the range hood, through which the controller 3 is in communication connection with the external temperature detecting terminal to receive the environmental temperature sent by the external temperature detecting terminal, so that the controller 3 can also obtain the environmental temperature. In this embodiment, the external temperature detection terminal may be an intelligent thermometer with a communication function, a mobile terminal (such as, but not limited to, a mobile phone, a tablet computer, etc.) integrated with a temperature sensor, or other household appliances (such as, but not limited to, a disinfection cabinet, a refrigerator, etc.) with a communication function and integrated with an external temperature sensor. Optionally, the communication receiver is a wireless communication receiver, which may be, but not limited to, in communication connection with an external temperature detection terminal by WIFI, bluetooth, or the like.
Further, the air outlet 202 is located on the front surface of the air purifying device 2. It will be appreciated that the user typically stands in front of the kitchen range, i.e. in front of the range hood for cooking, and the air outlet 202 is provided on the front of the air cleaning device 2, so that the air outlet of the air cleaning device 2 can be conveniently directly applied to the user. Of course, in other embodiments, the air outlet 202 may be located at other positions of the air purifying device 2, such as the top surface or the side surface, and it is understood that in this case, the air outlet of the air purifying device 2 is difficult to directly act on the user, but can also act on the user to some extent in consideration of the diffusivity of the air outlet.
For the solution where the air outlet 202 is located in the front of the air purifying device 2, optionally, the air outlet 202 may be provided with an air guiding blade 23 extending transversely and obliquely downward forward or horizontally forward, so that the air outlet 202 can obliquely discharge air downward or horizontally forward, thereby being more beneficial for the air discharge of the air purifying device 2 to directly act on the user. Of course, in some embodiments, the wind guiding blades 23 may be rotatably disposed, so that the wind outlet direction of the wind outlet 202 is adjustable, and thus, when the wind outlet is required to directly act on the user, the wind outlet is rotated to a position extending obliquely forward and downward or horizontally forward (see fig. 6); when the circulation purification of the air in the kitchen is to be realized, the air guide blades 23 are rotated to a position (see fig. 7) extending obliquely forwards and upwards, so that the air outlet 202 is inclined forwards and upwards to discharge air, and the oil smoke in the upper half part of the kitchen space can be pushed to flow downwards to be contained in the circulation purification of the air, so that the oil smoke in the kitchen can be further reduced, and the improvement of the whole air quality of the kitchen space is facilitated; in particular, the upper half of the kitchen space is often subject to soot accumulation due to the thermal plume effect of soot.
In the present embodiment, referring to fig. 1 to 4, the range hood body 1 includes a decorative cover 11 and a fume collecting hood 12 provided below the decorative cover 11, and the fume suction duct is provided in the decorative cover 11. Further, the air purifying device 2 is arranged in the decorative cover 11, so that the air purifying device 2 is hidden in the decorative cover 11, and the appearance of the range hood can be more concise. Without loss of generality, the air outlet 202 is exposed on the front surface of the decorative cover 11, so that the clean air purified by the air purifying device 2 can be sent out into the kitchen space. However, the present design is not limited thereto, and in other embodiments, the air purifying device 2 may be disposed outside the decorative cover 11, for example, it may be disposed on the front side of the decorative cover 11 and above the fume collecting hood 12; the air purifying device 2 is arranged outside the decorative cover 11, so that the internal components (such as the filter 22, the purifying fan 21 and the like) can be conveniently maintained and disassembled; it will be appreciated that the air cleaning device 2 provided outside the decorative cover 11 does not require the decorative cover 11 to be removed during the process of removing the internal components thereof.

Referring to fig. 8, in an embodiment, the control method of the range hood includes the following steps:
s1, acquiring the ambient temperature of the range hood;
and S2, controlling the air output of the air purifying device of the range hood according to the environmental temperature.
According to the technical scheme, the environment temperature of the range hood can be obtained, meanwhile, the air outlet quantity of the air purifying device is adjustable, and it can be understood that the air outlet quantity of the air purifying device acts on a user, and the user has different air outlet quantity requirements on the air purifying device under different environment temperatures, so that the air outlet quantity of the air purifying device is controlled according to the environment temperatures, the air outlet quantity can meet the requirements of the user under the corresponding environment temperatures, and the body feeling of the user is more comfortable.
In one embodiment, the step S2 includes:
step S21, determining that the ambient temperature increases;
step S22, the air output of the air purifying device is controlled to be increased.
It will be appreciated that during cooking, the ambient temperature to which the range hood is exposed typically increases. In particular, in summer, the increase in the ambient temperature may cause discomfort to the user due to overheating, and at this time, the increase in the air output of the air cleaning device may cause the user to feel cooler and feel more comfortable.
However, in other embodiments, when the air purifying device is further provided with the electric auxiliary heating device to enable the air to be exhausted, for winter, the ambient temperature is very small at the beginning of cooking, at this time, the user needs the air purifying device to provide a relatively large amount of warm air, and along with the cooking activity, the ambient temperature is continuously increased, so that the user's demand for the amount of warm air is reduced, and at this time, the controller can control the air exhausting amount of the air purifying device to be reduced, so as to save energy.
In one embodiment, the step S22 specifically includes:
the rotating speed of the purifying fan of the air purifying device is controlled to be increased so as to increase the air output of the air purifying device.
The rotation speed of the purifying fan is increased, so that the air output can be increased, and the air output speed of the air purifying device can be increased, and a user experiences a cooler feeling.
However, the present design is not limited to this, and in other embodiments, when there are a plurality of purifying fans, the step S22 may further be specifically:
the starting number of the purifying fans of the air purifying device is controlled to be increased so as to increase the air output of the air purifying device.
It is understood that, no matter the plurality of purifying fans are arranged side by side or are sequentially arranged in the extending direction of the purifying air duct, the more the starting quantity of the purifying fans is, the larger the generated air quantity is. Of course, the way of changing the air output through the rotation speed adjustment of the purifying fan can enable the change of the air output to be relatively more continuously adjustable.
In one embodiment, the air purifying device is provided with a plurality of air volume gears, and different air volume gears correspond to different temperature intervals;
the step S2 specifically includes:
step S201, determining a temperature interval in which the ambient temperature is located;
step S202, controlling the air purifying device to output air at a corresponding air quantity gear.
Therefore, the number of times of change of the air output of the air purifying device can be reduced, and the control process of the air output of the air purifying device is simpler. Optionally, different air volume gears correspond to different rotational speeds of the purifying fan; or, different air quantity gears correspond to different starting numbers of the purifying fans. Of course, the air quantity gear corresponding to the higher temperature interval has larger corresponding rotating speed of the purifying fans or more starting quantity of the purifying fans.
For example, when the ambient temperature is within a temperature range of [24 ℃,28 ℃), the corresponding air volume gear is a first gear, and the first gear air volume is 0.5 times of the maximum air volume; when the ambient temperature is within a temperature range of [28 ℃ and 30 ℃), the corresponding air quantity gear is the second gear, and the second gear air quantity is 0.8 times of the maximum air quantity; when the ambient temperature is within the temperature range [30 ℃ and + ] infinity, the corresponding air volume gear is the third gear, and the third gear air volume is the maximum air volume.
In one embodiment, the step S1 specifically includes:
the ambient temperature is obtained by a temperature sensor arranged on the range hood.
That is, the range hood itself has a function of acquiring the ambient temperature, and thus, even when a network signal is absent, the ambient temperature can be immediately acquired, thereby controlling the air outlet amount of the air cleaning device according to the ambient temperature.
However, the present design is not limited thereto, and in some other embodiments, the step S1 may further be:
and receiving the environment temperature sent by the external temperature detection terminal.
In this way, the ambient temperature can also be obtained. In this embodiment, the external temperature detection terminal may be an intelligent thermometer with a communication function, a mobile terminal (such as, but not limited to, a mobile phone, a tablet computer, etc.) integrated with a temperature sensor, or other household appliances (such as, but not limited to, a disinfection cabinet, a refrigerator, etc.) with a communication function and integrated with an external temperature sensor. Optionally, the communication connection can be performed with the external temperature detection terminal by adopting a WIFI mode, a Bluetooth mode and the like.
The invention also provides a computer readable storage medium, wherein the computer readable storage medium is stored with a control program of the range hood, and the control program of the range hood realizes the steps of the control method of the range hood when being executed by a processor. Since the computer readable storage medium adopts all the technical solutions of all the embodiments, at least the beneficial effects brought by the technical solutions of the embodiments are provided, and will not be described in detail herein.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
