The invention provides a range hood 100.
In the embodiment of the present invention, as shown in fig. 1 and 2, the range hood 100 includes a housing 10, a baffle assembly 20 and a plurality of condensation plates 40. Wherein the shell 10 is provided with a smoke inlet 101; the guide plate assembly 20 comprises a guide plate 21 covered on the smoke inlet 101, a plurality of smoke collecting cavities 211 are arranged on one surface of the guide plate 21 opposite to the inner cavity of the shell 10 in a separation mode, and an air inlet 212 is formed in the inner wall surface of any smoke collecting cavity 211; the condensing plates 40 are correspondingly and movably covered on the smoke inlet sides of the smoke collecting cavities 211 to open or cover the air inlets 212 in the corresponding smoke collecting cavities 211.
In the present embodiment, the casing 10 is used to form the overall appearance of the range hood 100, and the casing 10 has a smoke inlet 101 and an inner cavity communicating with the smoke inlet 101. A fan assembly 30 is disposed in the inner cavity of the housing 10 to create a negative pressure at the smoke inlet 101 to draw the flow of cooking fumes into the inner cavity of the housing 10. The deflector assembly 20 is disposed at the smoke inlet 101 for guiding the flow of the smoke, so that the flow of the smoke can be converged into the smoke collecting cavity 211. The number and distribution of the smoke collecting cavities 211 on the baffle 21 can be set according to actual cookers, for example, the cookers used in families are generally left and right double cookers, correspondingly, the baffle 21 can be provided with two smoke collecting cavities 211 corresponding to the left and right double cookers respectively, of course, in some special application occasions, there are more cookers, and the number of the smoke collecting cavities 211 can be adjusted according to the actual number of the cookers. The smoke inlet side of each smoke collecting cavity 211 is movably provided with a condensing plate 40, so that the movement of the condensing plate 40 can be adjusted according to the actual cooking scene to open or cover the air inlet 212 in the corresponding smoke collecting cavity 211.
Specifically, a range hood 100 having dual chambers 211 and dual condensing panels 40 is illustrated. The kitchen ranges in the home generally have left and right cooking heads, correspondingly, the guide plate 21 is provided with left and right smoke collecting cavities 211, the smoke inlet sides of the left and right smoke collecting cavities 211 are respectively provided with a condensing plate 40, and the condensing plates 40 can move relative to the guide plate 21 to open or cover the air inlets 212 in the corresponding smoke collecting cavities 211. For example, when a user cooks, if only the left cooking range is used, the left condensation plate 40 can be used for opening the air inlet 212 in the left smoke collecting cavity 211, and the right condensation plate 40 can be used for closing the air inlet 212 in the right smoke collecting cavity 211, so that the negative pressure area is fully concentrated in the left smoke collecting cavity 211, and the smoke and fume generated by the left cooking range can be quickly sucked from the left air inlet 212 in a large amount. If only the left cooking range is used for cooking, but the oil smoke air flow generated by the left cooking range is too large, the corresponding air inlets 212 can be opened by the condensation plates 40 on the left side and the right side, so that the oil smoke air flow can be discharged as soon as possible. When the range hood 100 is closed, the condensation plate 40 on the left and right sides can be selectively covered with the corresponding air inlets 212.
By arranging the condensing plates 40 on the smoke inlet sides of the smoke collecting cavities 211 in a movable manner, a user has more selectivity in use, and thus the self-adaptive adjusting capability of the range hood 100 is effectively improved. There are various ways of moving the condensation plate 40, such as sliding, rotating or telescoping movement, etc. The condensation plate 40 may be movably mounted on the housing 10 or on the baffle 21. And because the condensation plate 40 is arranged on the smoke inlet side of the guide plate 21, namely, is positioned at the outermost side of the range hood 100, the movable stroke of the condensation plate 40 is not limited, and a larger movable space is provided, so that a proper movable stroke can be selected and set according to actual requirements, the range hood 100 has a better smoke absorbing effect, and the self-adaptive adjusting capability of the range hood 100 is further improved.
The range hood 100 of the invention is provided with a plurality of smoke collecting cavities 211 on the guide plate 21, the smoke inlet side of each smoke collecting cavity 211 is movably covered with a condensing plate 40, and the air inlet 212 in the corresponding smoke collecting cavity 211 is opened or covered by the movement of the condensing plate 40. Therefore, when a user cooks, the corresponding condensing plate 40 can be adjusted in a targeted manner according to the actual size of the oil smoke air flow, so that the oil smoke air flow in the corresponding area can enter the inner cavity of the shell 10 from the air inlet 212 of the smoke collecting cavity 211 in the corresponding area, the adjustment of the range hood 100 is more flexible, and the range hood has better adaptability and adjustment capability. Meanwhile, since the condensing plate 40 is arranged on the smoke inlet side of the guide plate 21, the movable space of the condensing plate 40 is larger, and the movable stroke is not limited, so that the movement amplitude of the condensing plate 40 can be set according to the actual requirements, and the adaptability of the range hood 100 is further improved.
In addition, through adopting the air inlet layout of a plurality of fume collecting cavities 211 and a plurality of condensing plates 40, the negative pressure area on the guide plate 21 can be effectively increased, and the effect of multi-surface fume inlet is realized, so that the fume suction effect can be well improved, the size of each condensing plate 40 is relatively smaller, and the condensing plates 40 are convenient to assemble, disassemble and clean.
Further, the inner wall surface of any one of the smoke collecting cavities 211 is provided with a plurality of air inlets 212. Specifically, the inner wall surface of the smoke collecting chamber 211 includes a bottom wall opposite to the smoke inlet 101, and a side wall extending forward from the circumference of the bottom wall, and the air inlet 212 may be provided on the bottom wall and/or the side wall. In practical application, the cooking ranges are usually arranged in a left-right direction, preferably, the air inlets 212 are arranged on the bottom wall and are arranged at intervals along the left-right direction, so as to be matched with the arrangement mode of the cooking ranges, and therefore a better fume absorbing effect is achieved. Regarding the number of the air inlets 212 in each smoke collecting cavity 211, it is preferable to set two air inlets 212 side by side along the left-right direction on the bottom wall of each smoke collecting cavity 211 according to actual requirements, and more preferable to set each air inlet 212 to be rectangular extending from front to back, so that an effective negative pressure area can be generated in four directions, namely front, back, left and right, so that the distribution of the negative pressure area is more balanced, and the smoke absorbing effect is further improved.
Further, the baffle assembly 20 further includes a plurality of air inlet grilles 22 corresponding to the air inlets 212 one to one, and any one of the air inlet grilles 22 covers the air inlet side corresponding to the air inlet 212. In this embodiment, the air inlet grille 22 is disposed at the air inlet 212, so as to guide and filter the fume. The air inlet grille 22 can be composed of a plurality of grille strips, or can be composed of a net surface with air inlet meshes. By arranging the air inlets 212 and arranging the air inlet grille 22 at each air inlet 212, the size of each air inlet grille 22 is relatively smaller, so that the disassembly, assembly and cleaning of the air inlet grille 22 are facilitated. For example, the small-sized air inlet grille 22 can be directly placed into professional cleaning equipment such as a dish washer for cleaning, so that the cleaning is convenient and rapid, the cleaning is more thorough, and the user experience can be well improved.
In order to further improve the adaptive adjustment capability of the range hood 100, an air inlet gap 102 is formed between any condensing plate 40 and the air inlet 212 in the corresponding smoke collecting cavity 211, and the opening of the air inlet gap 102 can be adjusted according to the change of the concentration of the oil smoke. The opening of the air intake gap 102 can be adjusted by adjusting the relative distance between the condensation plate 40 and the corresponding fume collecting cavity 211, specifically, when the fume concentration is gradually increased, the opening of the air intake gap 102 is correspondingly increased, and when the fume concentration is zero, the condensation plate 40 can realize seamless butt joint with the fume collecting cavity 211, so that the opening of the air intake gap 102 is zero. It should be noted that, the change of the oil smoke concentration can be manually adjusted according to the user's own perception, more preferably, an oil smoke concentration sensing device can be arranged on the range hood 100, and the change of the oil smoke concentration can be automatically detected and automatically adjusted through the range hood 100.
Further, the range hood 100 further includes a plurality of driving adjustment devices 50 disposed on the baffle 21 and corresponding to the plurality of condensation plates 40, where any one of the driving adjustment devices 50 is configured to drive the corresponding condensation plate 40 to move so as to adjust the opening of the corresponding air intake gap 102. In this embodiment, by correspondingly providing a driving adjustment device 50 on each condensation plate 40, each condensation plate 40 can move independently without being restricted by each other, so as to further improve the self-adaptive adjustment capability of the range hood 100. The drive adjustment device 50 may be realized by a link mechanism, a gear mechanism, or the like. Specifically, in one embodiment, any driving adjustment device 50 includes a driving motor and a telescopic rod penetrating forward out of the baffle 21, and the condensation plate 40 is mounted at a free end of the telescopic rod and is driven by the driving motor to perform telescopic motion to adjust the opening of the corresponding air intake gap 102.
Further, the range hood 100 further includes a controller and a plurality of oil smoke detecting devices 60, the plurality of oil smoke detecting devices 60 are in one-to-one correspondence with the plurality of smoke collecting cavities 211 to detect the oil smoke concentration of the smoke inlet side of the corresponding smoke collecting cavity 211, and the controller is configured to control the corresponding condensation plate 40 to open or cover the air inlet 212 in the corresponding smoke collecting cavity 211 according to the oil smoke concentration detected by the oil smoke detecting devices 60. In this embodiment, by setting the oil smoke detecting device 60 and the controller, the range hood 100 can automatically detect the oil smoke concentration of the smoke inlet side of the corresponding smoke collecting cavity 211 according to the oil smoke detecting device 60, and automatically control the movement of the condensation plate 40 through the controller, so as to realize the self-adaptive adjustment of the range hood 100 to achieve the optimal oil smoke absorbing effect, and effectively improve the user experience. The oil smoke detecting device 60 may be mounted on both sides of the condensing plate 40 or on both sides of the baffle 21.
The following describes in detail the control method of the range hood 100 according to the embodiment of the present invention with reference to fig. 3 to 6, wherein the range hood 100 is the range hood 100 according to the above embodiment of the present invention, and the specific structure of the range hood 100 refers to the above embodiment, so that at least all the advantages brought by the technical solutions of the above embodiment are provided, and will not be described in detail herein.
Specifically, the range hood 100 includes an adaptive adjustment mode, and the control method of the range hood 100 includes the steps of:
s1, entering an adaptive adjustment mode, and detecting the oil smoke concentration of a corresponding area by any oil smoke detection device 60;
s2, the controller controls the movement of the condensing plate 40 in the corresponding area according to the oil smoke concentration detected by the corresponding oil smoke detecting device 60; the step S2 specifically comprises the following steps:
s21, when the concentration of the oil smoke detected by any oil smoke detection device 60 is greater than or equal to a first preset value, the controller controls the condensation plate 40 corresponding to the oil smoke detection device 60 to open the air inlet 212 in the corresponding smoke collecting cavity 211;
s22, when any oil smoke detection device 60 does not detect an oil smoke signal or the detected oil smoke concentration is smaller than a first preset value, the controller controls the condensation plate 40 corresponding to the oil smoke detection device 60 to close the air inlet 212 in the corresponding smoke collecting cavity 211.
In this embodiment, after entering the adaptive adjustment mode, the range hood 100 can adjust the movement of the corresponding condensation plate 40 according to the specific range hood concentration, so as to achieve the best range hood effect. Specifically, the range hood 100 having the double smoke collecting cavities 211 matched with the double condensing plate 40 will be described as an example. As shown in fig. 2, the flow guide plate 21 of the range hood 100 is provided with a left and a right fume collecting cavities 211, and the fume inlet sides of the two fume collecting cavities 211 are respectively movably provided with a condensing plate 40.
When the range hood 100 is in the off state, as shown in fig. 3, the left and right condensation plates 40 respectively cover the air inlets 212 in the corresponding fume collecting cavities 211, and the range hood 100 has good integrity.
When the range hood 100 is in an operating state, the left and right condensation plates 40 are adjusted according to the actual oil smoke concentration. Referring to fig. 4 to 6 (arrows in the drawings indicate the flow direction of the oil smoke), the range hood 100 specifically includes the following working states, when the oil smoke detecting device 60 detects that the oil smoke concentration generated by the left cooking range is greater than a first preset value and the oil smoke concentration generated by the right cooking range is less than the first preset value, the range hood 100 enters the first working state, as shown in fig. 4, the controller controls the left condensation plate 40 to open the air inlet 212 in the left smoke collecting cavity 211, and the right condensation plate 40 covers the air inlet 212 in the right smoke collecting cavity 211, so as to ensure that the left smoke collecting cavity 211 has a larger negative pressure, so that the oil smoke is quickly sucked away. When the smoke detection device 60 detects that the concentration of the smoke generated by the left cooking range is smaller than the first preset value and the concentration of the smoke generated by the right cooking range is larger than the first preset value, the range hood 100 enters the second working state, as shown in fig. 5, at this time, the controller controls the right condensation plate 40 to open the air inlet 212 in the right smoke collecting cavity 211, and the left condensation plate 40 covers the air inlet 212 in the left smoke collecting cavity 211. When the oil smoke detecting device 60 detects that the oil smoke concentration generated by the cooking tops on the left and right sides is greater than the first preset value, the range hood 100 enters the third working state, as shown in fig. 6, and at this time, the controller controls the condensation plates 40 on the left and right sides to open the air inlets 212 in the corresponding smoke collecting cavities 211. It should be noted that the first preset value is the minimum concentration of the oil smoke sensed by the oil smoke detecting device 60.
Further, step S2 further includes: s23, when the concentration of the oil smoke detected by any one of the oil smoke detection devices 60 is greater than or equal to a second preset value, the controller controls the condensation plate 40 corresponding to the oil smoke detection device 60 and the condensation plate 40 adjacent to the condensation plate 40 to open the air inlet 212 in the corresponding smoke collecting cavity 211; wherein the second preset value is greater than the first preset value.
Specifically, the range hood 100 having the double smoke collecting chamber 211 matched with the double condensing plate 40 will be described as an example. For example, when the concentration of the oil smoke generated by the left cooking range is larger and the concentration of the oil smoke detected by the left oil smoke detecting device 60 is larger than the second preset value, the range hood 100 enters the third working state no matter whether the oil smoke is generated by the right cooking range or not, and the controller controls the left condensing plate 40 and the right condensing plate to simultaneously open the air inlets 212 in the corresponding smoke collecting cavities 211, so as to ensure that the oil smoke is discharged as soon as possible.
Further, an air inlet gap 102 is formed between any condensation plate 40 and the air inlet 212 in the corresponding smoke collecting cavity 211, and when the self-adaptive adjustment mode is in, the controller can adjust the opening of the corresponding air inlet gap 102 according to the change of the smoke concentration of the smoke inlet side of the corresponding smoke collecting cavity 211 detected by the smoke detecting device 60, and the opening of the air inlet gap 102 increases along with the increase of the smoke concentration. Thus, the range hood 100 can be adaptively adjusted according to the change of the oil smoke concentration, so as to ensure that the range hood has better oil smoke absorbing effect at any time.
Further, in order to meet the diversified demands of the users, the range hood 100 further includes a normal mode, and when the normal mode is selected, a fixed opening is maintained between any condensing plate 40 and the air inlet 212 in the corresponding smoke collecting cavity 211 for the flow of the smoke. The user can select the normal mode or the adaptive adjustment mode according to the self requirements. For example, when the cooking is finished, the range hood 100 needs to be turned on to exhaust the smoke smell in the kitchen, or other special occasions, the user can select the normal mode to exhaust the smoke. Thus, the selectivity of the user is greatly improved.
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.
