When people cook in a kitchen, people usually have great oil smoke and are stuffy in the air environment of the kitchen, and particularly in summer, the body of people is easy to feel uncomfortable. The conventional air conditioner used in the kitchen has the following problems: the oil fume generated in the cooking process cannot be prevented from being spilled into the environment to influence the health of human body. In the prior art, generally, air outlets are arranged around the cooking bench to form an air curtain, so that oil smoke generated at the cooking bench is limited, the range hood is convenient to extract, the oil smoke can be reduced from escaping, and the health of a human body is facilitated. However, in the cooking process, the air outlet of the air curtain is easily blocked by external tools such as kitchen ware and the like, so that the air curtain cannot be effectively formed, and the oil smoke still escapes.
The invention provides a kitchen ventilation system, which is used for adjusting the air quality of a cooking area; the upper air outlet and the lower air outlet are arranged around the cooking bench 400 and the smoke exhaust ventilator 300, so that 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 outlets are shielded, so that the escape amount of oil smoke when the air outlets are shielded is reduced, and the influence on the health of a human body caused by the overflow of the oil smoke and heat generated at the cooking bench 400 in the cooking environment can be effectively inhibited.
Specifically, referring to fig. 1, 2 and 3, the present invention provides a kitchen ventilation system including:
a hood 300;
a cooking bench 400, wherein the cooking bench 400 is arranged at the lower side of the range hood 300; and
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, the second air curtain device 200 has a second air duct, the second air duct has a second air outlet 200a, 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 range 400.
In the technical solution of the embodiment of the present invention, the first air curtain device 100 and the second air curtain device 200 are used to form an air curtain to reduce the escape of oil smoke. In the technical solution of the embodiment of the present invention, 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 outlet 200a of the second air duct of the second air curtain device 200 is 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 outlet 100a and the second outlet 200a is blocked, the second outlet 200a alone is difficult to form an air curtain, and 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 discharges air, and because the first air outlet 100a and the second air outlet 200a are arranged oppositely, the first air curtain device 100 can form an air curtain in an 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 form the air curtain together, and further, the kitchen ventilation system can form the air curtain when the second air outlet 200a is shielded, so that the air curtain sealing effect is ensured, the escaping amount of oil smoke when the area A between the first air outlet 100a and the second air outlet 200a is shielded is reduced, and further, the range hood 300 can pump away a large amount of oil smoke.
It should be noted that the kitchen ventilation system is a kitchen air conditioning device. The range hood 300 is used for exhausting oil smoke generated in the cooking area, and the first air curtain device 100 and the second air curtain device 200 mainly limit the oil smoke in the cooking area in a certain space by forming an air curtain, thereby reducing the escape of the oil smoke.
It should be noted that 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 100 a. The second air curtain device 200 has a second fan and a second air duct. The air duct opening of the second air duct is a second air outlet 200 a. Typically, the first fan and the second fan are each in communication with the outside atmosphere (and may also be in communication with the air near the air conditioner return). The first and second fans may be axial fans.
Generally, the first outlet 100a and the second outlet 200a are linear outlets, i.e. both are strip-shaped outlets. As shown in fig. 5 or 6, since the cooking hob 400 is mostly rectangular in configuration, four second air outlets 200a are respectively located at the periphery of the cooking hob 400. The number of the first outlets 100a is also four, and the first outlets are respectively opposite to the second 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 outlet 200a may share a second fan, that is: the number of the second air ducts can be four; of course, each second air outlet 200a may also use one second fan separately. The first air outlet 100a may also share one first fan, that is: the number of the first air ducts can be four; of course, each first air outlet 100a may also use one first fan separately.
It should be noted that the hood 300 may be integrated with the first air curtain device 100 into an integrated structure. For example, the first outlet 100a is disposed on four frame structures of the range hood 300. Of course, the first air curtain device 100 may be provided separately from the hood 300; the first air curtain device 100 is such that four first air outlets 100a are arranged around the body of the hood 300. The cooktop 400 and the second air curtain apparatus 200 may also be integrated into an integral configuration, that is: the second air outlet 200a is disposed on a peripheral plate of the cooking bench 400. Of course, the second air curtain device 200 may be provided separately from the cooking top 400, and the four second air outlets 200a are provided around the body of the cooking top 400.
Further, referring to fig. 1, a region a between the first outlet 100a and the second outlet 200a may be mathematically defined as follows: the area a defined by the second outlet port 200a forms a space area a when moving to the plane defined by the corresponding first outlet port 100a in the normal direction of the second outlet port 200 a. However, in most cases, due to the placement of the external tools such as the kitchen ware, the kitchen ware is easily placed on a part of the second outlet 200a directly, so that the second outlet 200a is blocked and occupies the area a between the first outlet 100a and the second outlet 200a, once the area a is blocked, the outlet air of the second outlet 200a is blocked, and no air curtain exists between the blocking object and the range hood.
As an alternative embodiment of the above 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 inside of the cooking bench 400; when the area a between the first outlet 100a and the corresponding second 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 of the present invention further has a second state: a second state in which the air outlet direction of the second air outlet 200a is inclined toward the inside of the cooking range 400; that is, the air-out direction of second air outlet 200a is partial to holding together the smoke chamber of smoke ventilator 300, and under the suction effect that holds together the smoke chamber, the air-out orientation of second air outlet holds together the smoke chamber and flows, forms the air curtain alone, restricts the oil smoke in littleer spatial range, and smoke ventilator 300 of being convenient for improves smoke ventilator 300's smoking efficiency to the oil smoke extraction. The second state is used for the case that the area a between the first outlet 100a and the corresponding second outlet 200a is not blocked, and at this time, the air curtain system is in the second air curtain mode.
The kitchen ventilation system that this embodiment provided has the operating condition that first air curtain device 100 and second air curtain device 200 form the air curtain jointly and the operating condition that second air curtain device 200 forms the air curtain alone, can deal with first air outlet 100a and corresponding respectively regional A between the second air outlet 200a is sheltered from and is not sheltered from two kinds of circumstances, has promoted kitchen ventilation system and has responded to under the multiple operating mode that oil smoke and heat that produce in the top of a kitchen range 400 department spill over to the kitchen environment in the ability that produces the influence to human health.
Generally, the second outlet 200a may be provided with a wind deflector rotatably connected to the air duct wall, and the wind direction of the second outlet 200a is adjusted by the wind deflector. The air deflector can be driven to rotate by a motor.
As an optional implementation manner of the above embodiment, the wind speed of the second air curtain device 200 in the first state is a first wind speed, and 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 smaller than the second wind speed. Specifically, the wind speed of the outlet wind of the second wind curtain device 200 can 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 at this time, the first air outlet 100a and the second air outlet 200a discharge air together. Generally, the shielded area a is only a part of the area a, and the area a between the other first outlet 100a and the second outlet 200a is not shielded, if the wind speed of the second outlet 200a is output according to the wind speed when the second air curtain device 200 is in the second state, the two rest of the airflow in the non-shielded area a will generate a large convection, which causes airflow turbulence, and the turbulent airflow may carry the oil smoke to escape, which results in a poor sealing effect of the air curtain. For this reason, the first wind speed needs to be less than the second wind speed, i.e.: when the second air curtain device 200 is switched from the second state to the first state to operate, the wind speed is reduced; when the second air curtain device 200 is operated from the first state to the second state, the wind speed is increased. The second air curtain device 200 is configured with a speed regulation function, for example, by adjusting the rotation speed and output power of the second fan.
As an optional implementation manner of the above 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; or, referring to fig. 4, a light receiving device 500a is disposed at the first outlet 100a, and a light emitting device 500b is disposed at the second 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 an area a between the first air outlet 100a and the corresponding second air outlet 200a is blocked; the controller 700 is connected to each of the first air curtain device 100 and the second air curtain device 200.
Specifically, the light emitting device 500b emits light, and the light receiving device 500a receives light. Referring to fig. 7, if the light emitted from 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, and 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 from 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 500 b; the light receiving device is an infrared light receiving device 500 a.
Since the first outlet 100a and the second outlet 200a are linear, the light emitting devices 500b and the light receiving devices 500a are linearly arrayed along the length direction of the first outlet 100a and the second outlet 200a for this purpose. The light emitting device 500b and the received-light receiving device 500a may be fixed to the first air duct wall and the second air duct wall, respectively; or may be disposed beside the first outlet 100a and the second outlet 200 a.
As an optional implementation manner of the above embodiment, the cooking bench 400 is square, the number of the second air outlets 200a is four, and each of the second air outlets 200a is respectively located on four sides of the cooking bench 400; each second outlet 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 this 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 outlet 200a may be controlled by the air guide plate. For example, when one side of the cooking bench 400 is a wall, the second air outlet 200a close to the wall may be in a normally closed state, so as to prevent the air outlet of the second air outlet 200a from colliding with the wall to generate turbulent airflow; and the remaining second outlet 200a is in an open state.
Moreover, since the air outlet direction can also be controlled by controlling the air deflector, each of the second outlets 200a is configured to be individually switched between the first state and the second state; for example, when one of the second outlets 200a is in the shielded state, the shielded second outlet 200a is in the first state, and the remaining second outlets 200a are in the second state, so that the formed air curtain effect is better.
As an optional implementation manner of the above embodiment, the kitchen ventilation system further includes an air conditioner, the air conditioner includes a cold air channel, the cold air channel has a cold air outlet, and the cold air outlet is disposed on a side of the cooking bench 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 cold air outlet 600 is communicated with an air conditioner. The cooking bench 400 is close to the outer edge of the second air outlet 200a on one side where the user stands, and can be provided with an air-conditioning cold air outlet 600 along the air outlet direction, and the air-conditioning cold air outlet 600 is communicated with the air outlet of the air conditioner, so that the cold air of the air conditioner is directly blown to the user, and the comfort of the user during cooking is improved.
The present invention also provides a method for controlling a kitchen ventilation system, which is used for controlling the kitchen ventilation system, and as shown in fig. 8, the method at least comprises the following steps:
s100, starting the range hood 300, and determining whether an area a between each first air outlet 100a and the corresponding second air outlet 200a is blocked;
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 outlet 100a and the second outlet 200a is blocked, the second outlet 200a is difficult to form an air curtain wall alone, and at this time, the first air curtain device 100 is started 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 discharges air, and because the first air outlet 100a and the second air outlet 200a are arranged oppositely, the first air curtain device 100 can form an air curtain in an 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 form the air curtain together, and further, the kitchen ventilation system can form the air curtain when the second air outlet 200a is shielded, so that the air curtain sealing effect is ensured, the escaping amount of oil smoke when the area A between the first air outlet 100a and the second air outlet 200a is shielded is reduced, and further, the range hood 300 can pump away a large amount of oil smoke.
As an optional implementation manner of the above embodiment, the second air curtain device 200 further has a second state that the air outlet direction of the second air outlet 200a is inclined toward the inside of the cooking top 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 operating, and controlling the second air curtain device 200 to be in the second state.
Specifically, if the air outlet direction of the area a between each first air outlet 100a and the corresponding second air outlet 200a is not blocked by the second air outlet 200a and deviates to the smoke collecting cavity of the range hood 300, the oil smoke is limited in a smaller space range, the range hood 300 can conveniently extract the oil smoke, and the smoke extraction efficiency of the range hood 300 is improved. The second state is used for the case that the area a between the first outlet 100a and the corresponding second outlet 200a is not blocked, and at this time, the air curtain system is in the second air curtain mode.
The air curtain system provided by the embodiment can enable the first air curtain device 100 and the second air curtain device 200 to jointly form an air curtain in a working state and enable the second air curtain device 200 to independently form an air curtain in a working state based on the control method, and can respectively cope with two conditions that the area A between the first air outlet 100a and the corresponding second air outlet 200a is shielded and is not shielded, so that the capability of the air curtain system for inhibiting the oil smoke and heat generated at the cooking bench 400 from overflowing to the kitchen environment to influence the health of a human body under various working conditions is improved.
As an alternative implementation manner of the foregoing embodiment, referring to fig. 10, the control method further includes: s101 a; if the area a between the first air outlet 100a and the corresponding second air outlet 200a is blocked, the wind speed of the second air curtain device 200 is reduced.
Generally, the shielded area a is only a part of the area a, and the area a between the other first outlet 100a and the second outlet 200a is not shielded, if the wind speed of the second outlet 200a is output according to the wind speed when the second air curtain device 200 is in the second state, the two rest of the airflow in the non-shielded area a will generate a large convection, which causes airflow turbulence, and the turbulent airflow may carry the oil smoke to escape, which results in a poor sealing effect of the air curtain. For this reason, the first wind speed needs to be less than the second wind speed, i.e.: when the second air curtain device 200 is switched from the second state to the first state to operate, the wind speed is reduced; when the second air curtain device 200 is operated from the first state to the second state, the wind speed is increased. The second air curtain device 200 is configured with a speed regulation function, for example, by adjusting the rotation speed and output power of the second fan.
Generally, the kitchen ventilation system comprises: at least one controller 700, at least one memory, and a control program of a kitchen ventilation system stored on the memory and executable on the controller 700, the control program of the kitchen ventilation system being configured to implement the steps of the preceding control method.
