When people cook in a kitchen, the kitchen air environment is usually quite heavy and smoky due to the fact that the kitchen air environment is quite oily, and particularly in summer, people are easy to generate discomfort. Whereas the conventional air conditioner is used in a kitchen, there are the following problems: the cooking fume generated in the cooking process cannot be prevented from being scattered into the environment, and the health of a human body is influenced. In the prior art, the air outlets are generally arranged at the periphery of the cooking bench to form the air curtain, so that the cooking fume generated at the cooking bench is limited, the smoke exhaust ventilator is convenient to extract, the escape of the cooking fume can be reduced, and the cooking fume exhaust ventilator is beneficial to health. However, in the cooking process, external tools such as kitchen tools are easy to shield the air outlet of the air curtain, the air curtain cannot be effectively formed, and the oil smoke still escapes.
The application provides a kitchen ventilation system which is used for adjusting the air quality of a cooking area; by arranging the upper air outlet and the lower air outlet around the cooking bench 400 and the smoke exhaust ventilator 300, a multi-surface air curtain wall is formed between the cooking bench 400 and the smoke exhaust ventilator 300, and an air curtain forming mode is provided when the air outlet is shielded, so that the escape amount of oil smoke when the air outlet is shielded is reduced, and the oil smoke and heat generated at the cooking bench 400 during cooking can be effectively inhibited from overflowing into the kitchen environment to influence the health of a human body.
Specifically, referring to fig. 1, 2 and 3, the present application proposes a kitchen ventilation system comprising:
a smoke exhaust ventilator 300;
a cooking bench 400, wherein the cooking bench 400 is arranged at the lower side of the smoke exhaust ventilator 300; and
the first air curtain device 100, wherein the first air curtain device 100 is provided with a first air duct, the first air duct is provided with a first air outlet 100a, and the first air outlet 100a is arranged around the range hood 300; and
the second air curtain device 200, wherein the second air curtain device 200 is provided with a second air duct, the second air duct is provided with a second air outlet 200a, and the second air outlet 200a is arranged around the cooking bench 400; the first air outlet 100a is opposite to the corresponding second air outlet 200 a; the second air curtain device 200 has a first state in which the air outlet direction of the second air outlet 200a is perpendicular to the cooking bench 400.
In the technical solution of the embodiment of the present application, the first air curtain device 100 and the second air curtain device 200 are used for forming an air curtain to reduce the escape of oil smoke. In the technical solution of the embodiment of the present application, specifically, the first air outlet 100a of the first air duct of the first air curtain device 100 is disposed around the range hood 300; the second air outlets 200a of the second air duct of the second air curtain device 200 are disposed around the cooking bench 400. The second air curtain device 200 has a first state in which the air outlet direction of the second air outlet 200a is perpendicular to the cooking bench 400. Referring to fig. 2, when the area a between the first air outlet 100a and the second air outlet 200a is blocked, the second air outlet 200a is difficult to form an air curtain alone, and at this time, the first air curtain device 100 is activated and the second air curtain device 200 is in the first state. After the first air curtain device 100 is started, the first air outlet 100a is used for air outlet, and because the first air outlet 100a and the second air outlet 200a are opposite to each other, the first air curtain device 100 can form an air curtain in the area A where the second air curtain device 200 cannot form the air curtain, so that the first air curtain device 100 and the second air curtain device 200 jointly form the air curtain, and further the kitchen ventilation system can form the air curtain when the second air outlet 200a is shielded, ensure the air curtain sealing effect, reduce the escape amount of oil smoke when the area A between the first air outlet 100a and the second air outlet 200a is shielded, and further the range hood 300 can pump a large amount of oil smoke.
The kitchen ventilation system is a kitchen air conditioning apparatus. The range hood 300 is used for exhausting the oil smoke generated in the cooking area, and the first air curtain device 100 and the second air curtain device 200 limit the oil smoke in the cooking area to a certain space mainly by forming an air curtain, so that the escape of the oil smoke is reduced.
The first air curtain device 100 has a first fan and a first air duct. The air duct opening of the first air duct is a first air outlet 100a. The second air curtain apparatus 200 has a second fan and a second air duct. The air duct opening of the second air duct is a second air outlet 200a. Typically, the first fan and the second fan may be respectively connected to the outdoor air (or may be connected to air near the return air inlet of the air conditioner). The first fan and the second fan may be axial flow fans.
Generally, the first air outlet 100a and the second air outlet 200a are both linear air outlets, i.e. are both elongated air outlets. As shown in fig. 5 or 6, since the cooking bench 400 is mostly rectangular, the number of the second air outlets 200a is four, and they are respectively located around the cooking bench 400. The number of the first air outlets 100a is four, and the first air outlets are respectively opposite to the second air outlets 200a one by one. Of course, in some special cases, the number of the first air outlets 100a and the number of the second air outlets 200a may be customized, and may not be four, for example, may be three, or even two. The second air outlet 200a may share a second fan, that is: the second air channels can be four parallel connected air channels; of course, a single second fan may be used for each second air outlet 200a. The first air outlet 100a may also share a first fan, that is: the first air channels can be four parallel connected air channels; of course, a single first fan may be used for each first air outlet 100a.
It should be noted that the range hood 300 may be integrated with the first air curtain device 100 into a unitary structure. For example, the first air outlet 100a is provided on four frame structures of the range hood 300. Of course, the first air curtain apparatus 100 may be provided separately from the hood 300; the first air curtain device 100 is provided with four first air outlets 100a around the body of the range hood 300. The cooktop 400 and the second air curtain device 200 may also be integrated into a unitary construction, namely: the second air outlet 200a is provided on the peripheral plate body of the hob 400. Of course, the second air curtain apparatus 200 may be separately disposed from the hob 400, and four second air outlets 200a are disposed around the hob 400 body.
Further, referring to fig. 1, a region a between the first air outlet 100a and the second air outlet 200a may be defined in a mathematical manner: the area a defined by the second air outlet 200a forms a space area a when the area a moves to a plane defined by the corresponding first air outlet 100a in the normal direction of the second air outlet 200a. However, in most cases, due to the placement of external tools such as kitchen tools, the kitchen tools are easily placed directly on a part of the segments of the second air outlet 200a, so that the second air outlet 200a is blocked, the area a between the first air outlet 100a and the second air outlet 200a is occupied, and once the area a is blocked, the air outlet of the second air outlet 200a is blocked, so that no air curtain exists between the blocking object and the range hood.
As an alternative implementation of the foregoing embodiment, referring to fig. 3, the second air curtain device 200 further has a second state in which the air outlet direction of the second air outlet 200a is inclined toward the interior of the cooking bench 400; in the case that the area a between the first air outlet 100a and the corresponding second air outlet 200a is not blocked, the first air curtain device 100 stops operating, and the second air curtain device 200 is in the second state.
Specifically, the second air curtain device 200 according to the present application further has a second state: the air outlet direction of the second air outlet 200a is inclined toward the second state in the cooking bench 400; that is, the air outlet direction of the second air outlet 200a is deviated to the smoke collecting cavity of the smoke exhaust ventilator 300, under the suction action of the smoke collecting cavity, the air outlet of the second air outlet flows towards the smoke collecting cavity, and an air curtain is formed independently, so that the smoke exhaust ventilator 300 is convenient to extract the smoke and the smoke exhaust efficiency of the smoke exhaust ventilator 300 is improved. The second state is used for operating the air curtain system in the second air curtain mode when the area a between the first air outlet 100a and the corresponding second air outlet 200a is not shielded.
The kitchen ventilation system provided by the embodiment has the working state that the first air curtain device 100 and the second air curtain device 200 jointly form the air curtain and the working state that the second air curtain device 200 independently forms the air curtain, so that the two situations that the area A between the first air outlet 100a and the corresponding second air outlet 200a is shielded and not shielded can be respectively dealt with, and the capability of the kitchen ventilation system for preventing the oil smoke and the heat generated at the cooking bench 400 from overflowing into the kitchen environment during cooking under various working conditions to influence the human health is improved.
In general, an air deflector may be disposed at the second air outlet 200a, and the air deflector is rotatably connected to the air duct wall, so as to adjust the air outlet direction of the second air outlet 200a. The air deflector can be driven to rotate by a motor.
As an alternative implementation manner of the foregoing embodiment, the wind speed of the second air curtain device 200 in the first state is a first wind speed, the wind speed of the second air curtain device 200 in the second state is a second wind speed, and the first wind speed is less than the second wind speed. Specifically, the outlet wind speed of the second air curtain device 200 may be adjusted. When the second air curtain device 200 is in the first state, the first air curtain device 100 is in the working state, and the first air outlet 100a and the second air outlet 200a jointly outlet air. In general, the shielded area a is only a part of the area a, the other areas a between the first air outlet 100a and the second air outlet 200a are not shielded, if the wind speed of the second air outlet 200a is according to the wind speed when the second air curtain device 200 is in the second state, two air flows of the other areas a which are not shielded will generate larger convection, resulting in air flow disorder, and the turbulent air flows may carry oil smoke to escape, resulting in poor air curtain sealing effect. For this purpose, the first wind speed needs to be smaller than the second wind speed, i.e.: when the second air curtain device 200 is switched from the second state to the first state operation, the wind speed is reduced; when the second air curtain device 200 is switched from the first state to the second state operation, the wind speed is increased. The second air curtain device 200 is provided with a speed adjusting function, for example, by adjusting the rotation speed, the output power, and the like of the second fan.
As an alternative implementation of the foregoing embodiment, a light emitting device 500b is disposed at the first air outlet 100a, and a light receiving device 500a is disposed at the second air outlet 200 a; alternatively, referring to fig. 4, a light receiving device 500a is disposed at the first air outlet 100a, and a light emitting device 500b is disposed at the second air outlet 200 a; the kitchen ventilation system further comprises a controller 700; the controller 700 is connected to the light receiving device 500a, and is configured to determine whether the area a between the first air outlet 100a and the corresponding second air outlet 200a is blocked; the controller 700 is connected to the first air curtain device 100 and the second air curtain device 200, respectively.
Specifically, the light emitting device 500b emits light, and the light receiving device 500a receives light. Referring to fig. 7, if the light emitted by the light emitting device 500b is not received by the light receiving device 500a, the light receiving device 500a sends a first signal to the controller 700, the controller 700 receives the first signal from the light receiving device 500a, and determines that the area a between the first air outlet 100a and the corresponding second air outlet 200a is blocked, at this time, the controller 700 controls the second air curtain device 200 to operate in the first state, and the first air curtain device 100 is started. If the light emitted by the light emitting device 500b is received by the light receiving device 500a, the light receiving device 500a sends a second signal to the controller 700, and the controller 700 receives the second signal from the light receiving device 500a, and determines that the area a between the first air outlet 100a and the corresponding second air outlet 200a is not blocked, at this time, the controller 700 controls the second air curtain device 200 to operate in the second state, and the first air curtain device 100 stops operating.
In general, the light emitting device 500b is an infrared light emitting device 500b; the light receiving device is an infrared light receiving device 500a.
Since the first air outlet 100a and the second air outlet 200a are linear, the light emitting device 500b and the receiving light receiving device 500a are linearly arrayed along the length direction of the first air outlet 100a and the second air outlet 200a. The light emitting device 500b and the receiving light receiving device 500a may be fixed to the first air channel wall and the second air channel wall, respectively; the air flow paths may be provided beside the first air outlet 100a and the second air outlet 200a.
As an alternative implementation manner of the foregoing embodiment, the cooking bench 400 is square, the number of the second air outlets 200a is four, and each second air outlet 200a is located at four sides of the cooking bench 400; each of the second outlets 200a is configured to be individually switched between an open state and a closed state; the open state includes the first state and the second state.
In the present embodiment, each of the second outlets 200a may be individually switched between the open state and the closed state. The open state and the closed state of the second air outlet 200a may be controlled by the air deflector. For example, when one side of the cooking bench 400 is a wall, the second air outlet 200a near the wall may be in a normally closed state, so as to avoid the air outlet of the second air outlet 200a colliding with the wall to generate turbulent air flow; while the remaining second outlets 200a are in an open state.
Moreover, since the air outlet direction can also be controlled by controlling the air deflector, each of the second air outlets 200a is configured to be individually switched between the first state and the second state; for example, when one of the second air outlets 200a is in the blocked state, the blocked second air outlet 200a is in the first state, and the other second air outlets 200a are in the second state, so that the formed air curtain effect is better.
As an optional implementation manner of the foregoing embodiment, the kitchen ventilation system further includes an air conditioner, and the air conditioner includes a cold air channel, and the cold air channel has a cold air outlet, and the cold air outlet is disposed on a side of the cooking bench, which is close to the working area. The cold air outlet 600 is arranged at one side of the cooking bench 400 close to the working area; the cool air outlet 600 communicates with the air conditioner. The second air outlet 200a of the side of the cooking bench 400, which is close to the user, can be provided with an air conditioner cold air outlet 600 along the air outlet direction, and the air conditioner cold air outlet 600 is communicated with the air outlet of the air conditioner, so that cold air of the air conditioner can be conveniently and directly blown to the user, and the comfort of the user during cooking is improved.
The application also provides a control method of the kitchen ventilation system, which is used for controlling the kitchen ventilation system, and is shown by referring to fig. 8, and at least comprises the following steps:
s100, starting the range hood 300, and judging whether the area A between each first air outlet 100a and the corresponding second air outlet 200a is shielded;
s101, if the area A between each first air outlet 100a and the corresponding second air outlet 200a is blocked, controlling the first air curtain device 100 to start and controlling the second air curtain device 200 to be in the first state.
In this embodiment, when the range hood 300 is started, it is determined whether the area a between each first air outlet 100a and the corresponding second air outlet 200a is blocked; when the area a between the first air outlet 100a and the second air outlet 200a is blocked, the second air outlet 200a is difficult to form an air curtain wall alone, at which time the first air curtain device 100 is activated and the second air curtain device 200 is in the first state. After the first air curtain device 100 is started, the first air outlet 100a is used for air outlet, and because the first air outlet 100a and the second air outlet 200a are opposite to each other, the first air curtain device 100 can form an air curtain in the area A where the second air curtain device 200 cannot form the air curtain, so that the first air curtain device 100 and the second air curtain device 200 jointly form the air curtain, and further the kitchen ventilation system can form the air curtain when the second air outlet 200a is shielded, ensure the air curtain sealing effect, reduce the escape amount of oil smoke when the area A between the first air outlet 100a and the second air outlet 200a is shielded, and further the range hood 300 can pump a large amount of oil smoke.
As an alternative implementation of the foregoing embodiment, the second air curtain device 200 further has a second state in which the air outlet direction of the second air outlet 200a is inclined toward the inside of the cooking bench 400; referring to fig. 9, the control method further includes:
s102, if the area A between each first air outlet 100a and the corresponding second air outlet 200a is not blocked, controlling the first air curtain device 100 to stop running and controlling the second air curtain device 200 to be in the second state.
Specifically, if the area a between each first air outlet 100a and the corresponding second air outlet 200a is not blocked by the air outlet direction of the second air outlet 200a, the air outlet direction is deviated to the air collecting cavity of the range hood 300, so as to limit the range hood to a smaller space, facilitate the range hood 300 to extract the range hood, and improve the smoking efficiency of the range hood 300. The second state is used for operating the air curtain system in the second air curtain mode when the area a between the first air outlet 100a and the corresponding second air outlet 200a is not shielded.
The air curtain system provided in this embodiment, based on the above control method, can enable the first air curtain device 100 and the second air curtain device 200 to jointly form the working state of the air curtain and the second air curtain device 200 to independently form the working state of the air curtain, so as to respectively cope with the two situations that the area a between the first air outlet 100a and the corresponding second air outlet 200a is blocked and not blocked, and improve the capability of the air curtain system to cope with the situation that the cooking fume and heat generated at the cooking bench 400 during cooking are prevented from overflowing into the kitchen environment to affect the health of human body.
As an alternative implementation of the foregoing embodiment, referring to fig. 10, the control method further includes: s101a; if the area a between the first air outlet 100a and the corresponding second air outlet 200a is blocked, the air speed of the second air curtain device 200 is reduced.
In general, the shielded area a is only a part of the area a, the other areas a between the first air outlet 100a and the second air outlet 200a are not shielded, if the wind speed of the second air outlet 200a is according to the wind speed when the second air curtain device 200 is in the second state, two air flows of the other areas a which are not shielded will generate larger convection, resulting in air flow disorder, and the turbulent air flows may carry oil smoke to escape, resulting in poor air curtain sealing effect. For this purpose, the first wind speed needs to be smaller than the second wind speed, i.e.: when the second air curtain device 200 is switched from the second state to the first state operation, the wind speed is reduced; when the second air curtain device 200 is switched from the first state to the second state operation, the wind speed is increased. The second air curtain device 200 is provided with a speed adjusting function, for example, by adjusting the rotation speed, the output power, and the like of the second fan.
