Description

Technical Field

[0001] The invention relates to the technical field of range hood extraction equipment, and in particular to an adjustment component, a range hood extraction structure and a range hood. Background Art

[0002] With the continuous improvement of living standards and comprehensive quality, people's pursuit of the function and practicality of kitchen appliances is gradually increasing. Range hoods have become a necessary kitchen appliance because of their function of purifying the kitchen environment.

[0003] Generally, household gas appliances are located on the side of the range hood. When users cook, oil smoke is inhaled from one side of the oil net. However, air is also inhaled from the other side of the oil net at the same time, which weakens the range hood's suction capacity and causes energy waste. Summary of the invention

[0004] Based on this, in order to address the problem that the traditional range hoods weaken their suction capacity when in use, thereby causing energy waste, an adjustment component, a fume suction structure and a range hood are proposed, which can fully utilize their own fume suction capacity.

[0005] The specific technical solutions are as follows:

[0006] On the one hand, the present application relates to an adjustment component, comprising: an oil net, at least two shielding members and at least two oil fume detectors, the oil net being provided with at least two smoking holes, the smoking holes being arranged at intervals, the shielding member being connected to the oil net, the shielding member being used to open or close the smoking holes, and one shielding member corresponding to one smoking hole, the oil fume detector being connected to the oil net, the oil fume detector being used to detect whether the solubility of oil fume passing through the smoking holes is greater than a preset concentration value, and one oil fume detector corresponding to one smoking hole.

[0007] When the above-mentioned adjustment component is in use, the oil net is set on the mounting hole of the range hood, and the mounting hole of the range hood is connected with the smoking chamber of the range hood. The oil smoke detector is used to detect whether the concentration of the oil smoke passing through the oil smoke hole reaches a preset concentration value. When the oil smoke detector detects that the concentration of the oil smoke in the corresponding smoking hole is greater than the preset concentration value, the shielding member keeps the smoking hole open to allow the oil smoke to continue to pass through the smoking hole. When the oil smoke detector detects that the concentration of the oil smoke in the corresponding smoking hole is less than or equal to the preset concentration value, the smoking hole is blocked by the shielding member, thereby reducing the air inlet area of ​​the oil net and increasing the negative pressure at the smoking hole. This improves the utilization rate of the range hood and relatively saves energy consumption.

[0008] The technical solution is further described below:

[0009] In one embodiment, the shielding member is rotatably connected to the oil net.

[0010] In one embodiment, the oil net includes a first side wall and a second side wall opposite to the first side wall, the smoking hole penetrates both the first side wall and the second side wall, the oil smoke detector is connected to the first side wall, and the shielding member is rotatably connected to the second side wall.

[0011] In one of the embodiments, it further includes a controller and a rotatable member, the shielding member is connected to the oil net through the rotatable member, and the controller is in communication connection with the rotatable member and the oil smoke detector.

[0012] In one embodiment, the controller is disposed on the second side wall, and the controller and the oil smoke detector are spaced apart.

[0013] In one embodiment, the shielding member includes a first shielding body and a second shielding body, and the first shielding body and the second shielding body are both movably connected to the oil net;

[0014] Wherein, the shielding member includes a first working state and a second working state. When the shielding member is in the first working state, the first shielding body cooperates with the second shielding body to close the smoking hole. When the shielding member is in the second working state, the first shielding body cooperates with the second shielding body to open the smoking hole.

[0015] In one embodiment, the shielding member is retractable, and one end of the shielding member is movable relative to the oil net;

[0016] When the shielding member is in the extended state, the shielding member closes the smoking hole, and when the shielding member is in the retracted state, the shielding member opens the smoking hole.

[0017] In one of the embodiments, it also includes a driving mechanism, which is connected to the oil net. The shielding member can be wound and retracted. The shielding member includes a winding starting end and a winding ending end. The winding starting end is connected to the oil net, and the winding ending end is connected to the driving mechanism. The driving mechanism is used to drive the winding ending end to move to expand or retract the shielding member.

[0018] In one embodiment, the smoking hole is a strip-shaped hole, and the width of the smoking hole is smaller than the distance between two adjacent smoking holes.

[0019] On the other hand, the present application also relates to a fume absorbing structure, comprising the adjusting component in any of the above embodiments, and further comprising:

[0020] A mounting shell, wherein the mounting shell is provided with a smoking chamber and a mounting hole communicating with the smoking chamber, and the oil net is arranged in the mounting hole; and

[0021] A smoking device is arranged in the smoking chamber.

[0022] On the other hand, the present application also relates to a range hood, comprising the adjustment component in any of the above embodiments or the range hood structure in the above embodiments.

[0023] When the above-mentioned oil fume suction structure and range hood are in use, the oil net is set in the mounting hole of the range hood, and the mounting hole of the range hood is connected with the smoking chamber of the range hood. The oil fume detector is used to detect whether the concentration of the oil fume is greater than the preset concentration value of the smoking hole. When the oil fume detector detects that the concentration of the oil fume in the corresponding smoking hole is greater than the preset concentration value, the shielding member keeps the smoking hole open to allow the oil fume to continue to pass through the smoking hole. When the oil fume detector detects that the concentration of the oil fume in the corresponding smoking hole is less than or equal to the preset concentration value, the smoking hole is blocked by the shielding member, thereby reducing the air inlet area of ​​the oil net and increasing the negative pressure at the smoking hole. This improves the utilization rate of the range hood and relatively saves energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

[0033] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0034] The oil net in the traditional range hood is fully open. When the user cooks, the oil smoke is sucked from one side of the oil net, and the part of the other side of the oil net without oil smoke also sucks air at the same time, which causes a great waste of the range hood's suction capacity. Based on this, in order to address the problem that the traditional range hood weakens its suction capacity when in use, thereby causing a waste of energy, an adjustment component 10, an oil smoke suction structure and a range hood are proposed. The adjustment component 10 can control the closing of the suction hole 230 according to the direction of the oil smoke, thereby making full use of the oil smoke suction capacity of the range hood; the oil smoke suction structure and the range hood include the above-mentioned adjustment component 10, so the oil smoke suction structure and the range hood can make full use of their own oil smoke suction capacity.

[0035] The oil fume absorbing structure in one embodiment includes an adjustment component 10, a mounting shell and a smoking device. The mounting shell is provided with a smoking chamber and a mounting hole connected to the smoking chamber. The smoking device is arranged in the smoking chamber. The adjustment component 10 is arranged in the mounting hole to adjust the air inlet area of ​​the mounting hole. In this way, the oil fume generated during the cooking process enters the smoking chamber along the mounting hole through the smoking device. The air inlet area of ​​the mounting hole is adjusted by the adjustment component 10 to maximize the smoking capacity of the oil fume absorbing structure.

[0036] Optionally, the smoking device may be a fan or a blower or the like.

[0037] Please refer to Figure 1 and Figure 2 Specifically, the adjustment component 10 includes an oil net 200, at least two shielding members 100 and at least two oil fume detectors 300. The oil net 200 is arranged in the mounting hole. The oil net 200 is provided with at least two smoking holes 230. The smoking holes 230 are arranged at intervals. The shielding member 100 is connected to the oil net 200. The shielding member 100 is used to open or close the smoking hole 230, and one shielding member 100 corresponds to one smoking hole 230. The oil fume detector 300 is connected to the oil net 200. The oil fume detector 300 is used to detect whether the solubility of oil fume passing through the smoking hole 230 is greater than a preset concentration value, and one oil fume detector 300 corresponds to one smoking hole 230.

[0038] When the above-mentioned adjustment component 10 and the oil fume absorbing structure are in use, the oil net 200 is set in the mounting hole of the range hood, and the mounting hole of the range hood is connected to the smoking chamber of the range hood. The oil fume detector 300 detects whether the solubility of the oil fume passing through the smoking hole 230 is greater than the preset concentration value. When the oil fume detector 300 detects that the concentration of the oil fume in the corresponding smoking hole 230 is greater than the preset concentration value, the shielding member 100 keeps the smoking hole 230 open, so that the oil fume continues to pass through the smoking hole 230. When the oil fume detector 300 detects that the concentration of the oil fume in the corresponding smoking hole 230 is less than or equal to the preset concentration value, the smoking hole 230 is blocked by the shielding member 100, thereby reducing the air inlet area of ​​the oil net 200 and increasing the negative pressure at the smoking hole 230. In this way, the utilization rate of the range hood is improved and energy consumption is relatively saved.

[0039] Specifically, the preset concentration value is set according to user needs. When the preset concentration value is 0, at this time, when the oil smoke detector 300 detects that the concentration of the oil smoke in the corresponding smoking hole 230 is less than or equal to 0, that is, no oil smoke is detected passing through the smoking hole 230, the smoking hole 230 is blocked by the covering member 100, thereby reducing the air inlet area of ​​the oil net 200 and increasing the negative pressure at the smoking hole 230. In this way, the utilization rate of the range hood is improved and energy consumption is relatively saved.

[0040] Please refer to Figure 1Optionally, the oil net 200 may be in a long strip structure, and the number of the smoking holes 230 is multiple, and the smoking holes 230 are arranged at intervals along the length direction of the oil net 200.

[0041] Optionally, the shielding member 100 may be a shielding plate, and may be made of metal or non-metal material, as long as it can shield the smoking hole 230 .

[0042] Optionally, the oil smoke detector 300 may be an oil smoke concentration sensor.

[0043] It is necessary to explain that the oil net 200 is disposed in the mounting hole. The oil net 200 can be disposed on the hole wall of the mounting hole, or the oil net 200 can be disposed on the outer wall of the mounting shell but the oil net 200 can cover the mounting hole.

[0044] Please refer to Figure 1 Specifically, in one embodiment, the smoking hole 230 is a strip-shaped hole, and the width of the smoking hole 230 is smaller than the distance between two adjacent smoking holes 230. In this way, the wind resistance of the strip-shaped smoking hole 230 is relatively small. When the distance between each two adjacent smoking holes 230 is greater than the width of the smoking hole 230, it is convenient to install the shielding member 100.

[0045] Specifically, in one embodiment, the shielding member 100 is rotatably connected to the oil net 200 , so that the smoke-intake hole 230 can be opened or closed by rotating the shielding member 100 .

[0046] In other embodiments, the shielding member 100 can also open or close the smoking hole 230 by moving relative to the smoking hole 230 . For example, the shielding member 100 can be movably disposed on the oil net 200 .

[0047] Please refer to Figure 1 and Figure 2 Further, on the basis of the aforementioned embodiment, the oil net 200 includes a first side wall 210 and a second side wall 220 opposite to the first side wall 210, the smoking hole 230 penetrates both the first side wall 210 and the second side wall 220, the oil smoke detector 300 is connected to the first side wall 210, and the shielding member 100 is rotatably connected to the second side wall 220, so that when in use, the first side wall 210 faces the cooking equipment, when the oil smoke flows to the first side wall 210, the oil smoke detector 300 located on the first side wall 210 does not sense the oil smoke passing through the smoking hole 230, then the smoking hole 230 is closed by rotating the corresponding shielding member 100; if other oil smoke detectors 300 located on the first side wall 210 sense the oil smoke passing through the smoking hole 230, then the shielding member 100 is in a state of keeping the smoking hole 230 open.

[0048] Furthermore, in the present embodiment, the oil fume suction structure also includes a controller and a rotatable part. The shielding part 100 is connected to the oil net 200 through the rotatable part. The controller is communicated with the rotatable part and the oil fume detector 300. In this way, when the oil fume detector 300 does not detect that the concentration of the oil fume is greater than the smoking hole 230 corresponding to the preset concentration value, the controller controls the rotatable part to rotate to close the smoking hole 230, thereby reducing the air inlet area of ​​the oil net 200 and increasing the negative pressure at the smoking hole 230. This improves the utilization rate of the range hood and relatively saves energy consumption.

[0049] Furthermore, in this embodiment, the controller is disposed on the second side wall 220 , and the controller and the oil smoke detector 300 are spaced apart.

[0050] Optionally, the rotatable member includes a rotating shaft and a motor connected to the rotating shaft, and the controller controls the motor to rotate to drive the rotating shaft to drive the shielding member 100 to rotate.

[0051] Optionally, the controller may be a microcontroller unit or a single chip microcomputer.

[0052] The manner in which the shielding member 100 shields the smoking hole 230 will be further described below in conjunction with an embodiment.

[0053] In one embodiment, the shielding member 100 includes a first shielding body and a second shielding body, and the first shielding body and the second shielding body are both movably connected to the oil net 200. Further, the shielding member 100 includes a first working state and a second working state. When the shielding member 100 is in the first working state, the first shielding body and the second shielding body cooperate to close the smoking hole 230, and when the shielding member 100 is in the second working state, the first shielding body and the second shielding body cooperate to open the smoking hole 230. In this way, the first shielding body and the second shielding body open or close the smoking hole 230 in a manner similar to a "double door".

[0054] Optionally, the first shielding body and the second shielding body can be shielding plates, which can be made of metal or non-metal, as long as they can block the smoking hole 230. The way in which the first shielding body and the second shielding body are rotatably connected to the oil net 200 can be achieved by existing technologies and will not be elaborated here.

[0055] In another embodiment, the shielding member 100 is connected to the oil net 200, and the shielding member 100 can be retracted, and one end of the shielding member 100 can move relative to the oil net 200, so that when the oil smoke detector 300 detects that no oil smoke enters the smoke-collecting hole 230, the shielding member 100 can be in an expanded state, and then the shielding member 100 closes the smoke-collecting hole 230, thereby reducing the air intake area of ​​the oil net 200, increasing the negative pressure at the smoke-collecting hole 230, and then improving the utilization rate of the range hood, and relatively saving energy consumption. When the oil smoke detector 300 detects that oil smoke enters the smoke-collecting hole 230, the shielding member 100 can be in a retracted state, and then the shielding member 100 opens the smoke-collecting hole 230.

[0056] Specifically, the shielding member 100 may have a variety of retractable structures. For example, in this embodiment, the shielding member 100 can be wound and retracted. The shielding member 100 includes a winding starting end and a winding ending end. The winding starting end is connected to the oil net 200, and the winding ending end is connected to the driving mechanism. The driving mechanism drives the winding ending end to move to make the shielding member 100 expand or contract. At this time, the shielding member 100 can be a memory material, and the structure is similar to a coil spring in a wound state. When the shielding member 100 is in a natural state, the shielding member 100 is in a wound state. Under the drive of the driving mechanism, the winding ending end of the shielding member 100 moves along the direction of unfolding the shielding member 100 and unfolds the shielding member 10 0, thereby closing the smoking hole 230; when the smoking hole 230 needs to be opened, the shielding member 100 is driven by the driving mechanism, and the winding end end moves in the direction of contracting the shielding member 100 to contract the shielding member 100; of course, the shielding member 100 can also be a deformable material that can be bent and wound on the corresponding winding axis. The shielding member 100 is driven by the driving mechanism, and the winding end end moves in the direction of unfolding the shielding member 100 and unfolds the shielding member 100, thereby closing the smoking hole 230; when the smoking hole 230 needs to be opened, the shielding member 100 is driven by the driving mechanism, and the winding end end moves in the direction of contracting the shielding member 100 to contract the shielding member 100. Among them, the winding starting end is connected to the oil net 200, which can be directly connected to the oil net 200 or connected to the oil net 200 through an intermediate connecting member.

[0057] Specifically in this embodiment, the driving mechanism includes a mobile driving member and a winding driving component, the winding starting end is connected to the winding driving component, and the winding ending end is connected to the power output end of the mobile driving member. There are many ways for the winding driving component to drive the shielding member 100 to wind and shrink. For example, in one embodiment, the winding driving component includes a coil spring and a rotating shaft, and the rotating shaft is rotatably connected to the oil net 200. One end of the coil spring is connected to the rotating shaft and is wound around the rotating shaft with the rotating shaft as the winding axis. The other end of the coil spring is connected to the winding starting end, and the winding ending end is connected to the output end of the mobile driving member. , the coil spring is used to drive the shielding member 100 to wind around the rotating shaft, and the mobile driving member drives the winding end end to move so that the shielding member 100 is expanded or contracted. At this time, when the mobile driving member drives the winding end end to move along the direction of the shielding member 100 to expand, the shielding member 100 is expanded, and the shielding member 100 will drive the coil spring to expand, thereby closing the smoking hole 230; when the mobile driving member drives the winding end end to move along the direction of the shielding member 100 to contract, at this time, the shielding member 100 is driven to wind and contract under the action of the restoring force of the coil spring to restore its own deformation, thereby opening the smoking hole 230. In this embodiment, the rotation of the rotating shaft can be driven by a motor, and the mobile driving member can be a telescopic member, which drives the shielding member 100 to expand through the telescopic movement of the telescopic member. When the shielding member 100 needs to be wound, the telescopic member telescopes and moves along the rotation of the rotating shaft to allow the shielding member 100 to be wound around the rotating shaft.

[0058] In addition, an embodiment also relates to a range hood, including the adjustment component 10 in any of the above embodiments or the range hood structure in the above embodiments.

[0059] When the above-mentioned adjustment component 10, oil fume suction structure and range hood are in use, the oil net 200 is set in the mounting hole of the range hood, and the mounting hole of the range hood is connected to the smoking chamber of the range hood. The oil fume detector 300 detects whether the solubility of the oil fume passing through the smoking hole 230 is greater than the preset concentration value. When the oil fume detector 300 detects that the concentration of the oil fume in the corresponding smoking hole 230 is greater than the preset concentration value, the shielding member 100 keeps the smoking hole 230 open, so that the oil fume continues to pass through the smoking hole 230. When the oil fume detector 300 detects that the concentration of the oil fume in the corresponding smoking hole 230 is less than or equal to the preset concentration value, the smoking hole 230 is blocked by the shielding member 100, thereby reducing the air inlet area of ​​the oil net 200 and increasing the negative pressure at the smoking hole 230. This improves the utilization rate of the range hood and relatively saves energy consumption.
