Description

Technical Field

[0001] The utility model particularly relates to a range hood. Background Art

[0002] Range hoods have become one of the indispensable kitchen appliances in modern families. Usually, range hoods include top suction type and near (side) suction type. Side suction range hoods use the principle of vortex wind pressure to absorb most of the oil smoke close to the stove in an arc form, which can reduce the adverse effects on human health. The low-absorption range hoods currently on the market have lower air inlets. Their design concept is to place the air inlet as close to the stove as possible to improve the oil smoke absorption effect.

[0003] However, in actual use, it is found that the effect of absorbing oil smoke from lower air inlets is average when used with cookers, and that lower air inlets cannot absorb oil smoke at the corresponding height when used with cookers at higher heights, causing oil smoke and steam to fill the kitchen, reducing the user experience. The prior art usually adds air inlets at higher locations to absorb oil smoke from cookers at higher heights, but oil smoke is easy to escape when facing the oil smoke generated by cookers at higher heights, which results in poor oil smoke absorption effect. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a range hood in order to overcome the defect of poor oil fume adsorption effect in the prior art.

[0005] The utility model solves the above technical problems through the following technical solutions:

[0006] A range hood, the range hood comprising a first air inlet and a second air inlet, the second air inlet being located above the first air inlet along a projection direction of a cooker, the first air inlet being provided with a first smoke baffle, the second air inlet being provided with a second smoke baffle, the first smoke baffle and the second smoke baffle being able to close or open the first air inlet and the second air inlet, a guide area being formed between the first smoke baffle and the first air inlet when the first smoke baffle is opened, and / or between the second smoke baffle and the second air inlet when the second smoke baffle is opened, and being located in the projection direction of the cooker;

[0007] The range hood also includes a distance sensor, which is used to detect the height of the cooker;

[0008] A driving mechanism is provided between the first air inlet and the first smoke baffle, and between the second air inlet and the second smoke baffle, respectively. The distance measuring sensor and the driving mechanism are both electrically connected to a control panel.

[0009] In this solution, two air inlets of different heights are arranged along the projection direction of the cooker, namely, the first air inlet and the second air inlet of different heights, so as to adsorb the oil fume or steam for the cookers of different heights in a targeted manner. At the same time, when the first smoke baffle is opened, it forms a diversion area with the first air inlet. Similarly, when the second smoke baffle is opened, it can also form a diversion area with the second air inlet, so as to guide the oil fume in the projection direction of the cooker, improve the oil fume adsorption effect of the first air inlet and the second air inlet, and reduce the escape of oil fume. Furthermore, by setting a distance sensor and a driving mechanism and electrically connecting them to the control board, the first air inlet or the second air inlet is opened correspondingly for the cookers of different heights, so as to prevent the cooker from being too high and interfering with the cooker with a higher height when the first smoke baffle is opened. In addition, for the cooker whose height exceeds the second air inlet, the distance sensor can send an interference signal in time to prompt the user to replace the cooker in time, avoid the interference between the cooker and the range hood and the inability to effectively adsorb the oil fume, thereby improving the actual use experience of the user.

[0010] Preferably, the distance between the edge of the first smoke baffle facing the stove and the stove is 350-400 mm, and / or the distance between the edge of the second smoke baffle facing the stove and the edge of the first smoke baffle away from the stove is 50-150 mm.

[0011] In the present solution, the above-mentioned arrangement can prevent the first smoke baffle from being too close to the cooker and sucking the flame into the first air inlet. At the same time, the above-mentioned range can ensure that a large amount of oil smoke generated by the cooker with a lower height is sucked away in time. The second smoke baffle is spaced apart from the first smoke baffle, so that when the first smoke baffle interferes with the cooker with a higher height, the second smoke baffle can be smoothly opened and absorb the oil smoke or steam.

[0012] Preferably, the first smoke baffle has the same shape as the first air inlet and a size of the first smoke baffle is greater than or equal to a size of the first air inlet, and the second smoke baffle has the same shape as the second air inlet and a size of the second smoke baffle is greater than or equal to a size of the second air inlet.

[0013] In the present solution, through the above arrangement, the first air inlet or the second air inlet can be effectively blocked when the first smoke baffle or the second smoke baffle is closed, thereby ensuring the sealing of the first air inlet or the second air inlet.

[0014] Preferably, the dimension of the first smoke baffle along the projection direction of the cooker is 200-250 mm, and the dimension of the second smoke baffle along the projection direction of the cooker is 150-200 mm.

[0015] In this solution, through the above-mentioned arrangement, the guide area formed by the first smoke baffle and the first air inlet when it is opened, and the guide area formed by the second smoke baffle and the second air inlet when it is opened can effectively absorb oil smoke and steam.

[0016] Preferably, the size of the first air inlet is larger than the size of the second air inlet.

[0017] In this solution, through the above-mentioned arrangement, the oil smoke can be effectively extracted by increasing the size of the air inlet when frying, deep-frying, stir-frying, etc., which produces a lot of oil smoke for the cooker with a relatively low height.

[0018] Preferably, the range hood also includes a third air inlet, which is located above the second air inlet along the projection direction of the cooker, or the range hood also includes the third air inlet and a fourth air inlet, which is located above the third air inlet along the projection direction of the cooker.

[0019] In the present solution, the range hood is made suitable for cookers with higher heights by adding air inlets, for example, the range hood also includes a third air inlet and a fourth air inlet.

[0020] Preferably, the range hood also includes a lower shell, the lower shell having a smoke guide cavity therein, the first air inlet and the second air inlet are both arranged on the lower shell and are both connected to the smoke guide cavity, the lower shell extends toward the stove, and the lower shell is located on the side of the stove along the projection direction.

[0021] In this solution, the first air inlet and the second air inlet are arranged at different heights of the lower shell through the above arrangement, and oil smoke or steam is effectively removed by being connected to the smoke guide cavity. The lower shell extends toward the stove to form a low-absorption range hood, which quickly extracts oil smoke by getting closer to the cooker along the height direction of the stove to prevent the oil smoke from escaping.

[0022] Preferably, the range hood further comprises a fan mechanism, which is disposed on a side of the lower shell away from the stove top, has an air outlet, and is communicated with the smoke guide cavity.

[0023] In this solution, the above arrangement is used to effectively discharge the sucked smoke and steam from the air outlet.

[0024] Preferably, the distance measuring sensor is arranged between the second air inlet and the fan mechanism.

[0025] In this solution, through the above-mentioned setting, compared with setting the distance measuring sensor on the fan mechanism, on the one hand, the influence of vibration of the fan mechanism on the distance measuring accuracy when it is working is avoided; on the other hand, the distance measuring sensor is closer to the cooker, the time required for distance measurement is correspondingly reduced, and the response is faster.

[0026] Preferably, the length of the first air inlet is greater than or equal to the length of two cooking utensils arranged side by side along the length direction of the stove.

[0027] In this solution, through the above-mentioned arrangement, by increasing the length of the first air inlet, it is possible to effectively absorb oil smoke when multiple cooking utensils are used at the same time.

[0028] The positive progress effect of the utility model is that the utility model arranges two air inlets of different heights along the projection direction of the cooker, namely, the first air inlet and the second air inlet of different heights, so as to adsorb oil smoke or steam for cookers of different heights in a targeted manner. At the same time, when the first smoke baffle is opened, it forms a diversion area with the first air inlet. Similarly, when the second smoke baffle is opened, it can also form a diversion area with the second air inlet, so as to guide the oil smoke in the projection direction of the cooker, improve the oil smoke adsorption effect of the first air inlet and the second air inlet, and reduce the escape of oil smoke. Further, by arranging a distance sensor and a driving mechanism and electrically connecting them with the control panel, the first air inlet or the second air inlet is opened correspondingly for cookers of different heights, so as to prevent the cooker from being too high and interfering with the cooker with a higher height when the first smoke baffle is opened. In addition, for the cooker whose height exceeds the second air inlet, the distance sensor can send an interference signal in time to prompt the user to replace the cooker in time, avoid the interference between the cooker and the range hood and the inability to effectively adsorb oil smoke, thereby improving the actual use experience of the user.

[0045] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0046] This embodiment provides a range hood, the specific structure of which is as follows Figure 1 , Figure 2 and Figure 3 As shown, the range hood comprises a first air inlet 1 and a second air inlet 2, the second air inlet 2 is located above the first air inlet 1 along the projection direction of the cooker 4, a first smoke baffle 11 is provided on the first air inlet 1, and a second smoke baffle 21 is provided on the second air inlet 2, the first smoke baffle 11 and the second smoke baffle 21 can close or open the first air inlet 1 and the second air inlet 2, when the first smoke baffle 11 is opened, a guide area 8 is formed between the first air inlet 1 and / or the second smoke baffle 21 is opened and the second air inlet 2 and is located in the projection direction of the cooker 4;

[0047] The range hood also includes a distance sensor 3, which is used to detect the height of the cooker 4;

[0048] The driving mechanism (not shown in the figure) is respectively arranged between the first air inlet 1 and the first smoke baffle 11, and between the second air inlet 2 and the second smoke baffle 21. The distance sensor 3 and the driving mechanism are electrically connected to the control board (not shown in the figure).

[0049] Specifically, the range hood is provided with a first air inlet 1 and a second air inlet 2 of different heights along the projection direction of the cooker 4, wherein the height of the second air inlet 2 is higher than that of the first air inlet 1, so as to specifically absorb oil smoke or steam for cookers 4 of different heights. It is understandable that in other embodiments, multiple air inlets may be provided, for example, a third air inlet (not shown in the figure) and a fourth air inlet (not shown in the figure), and when only the third air inlet is provided, the third air inlet is located above the second air inlet 2 along the projection direction of the cooker 4 and is spaced apart from the second air inlet 2, and when both the third air inlet and the fourth air inlet are provided, the fourth air inlet is located above the third air inlet along the projection direction of the cooker 4, and the second air inlet 2, the third air inlet and the fourth air inlet are sequentially spaced apart along the projection direction of the cooker 4, so as to specifically absorb oil smoke or steam for cookers 4 of different heights.

[0050] It should be noted that, in this embodiment, the heights of the first air inlet 1, the second air inlet 2 and the cooker 4 are all based on the surface flush with the top of the stove 5. The distance sensor 3 is a sensor used for measurement and recording in the prior art, which can be a laser distance sensor or other sensors for measuring distance, and will not be described in detail here.

[0051] The first smoke baffle 11 and the second smoke baffle 21 are both flat plates, and a driving mechanism is provided in the range hood corresponding to the first air inlet 1 and the second air inlet 2. The driving mechanism may be a structure used in the prior art to drive the first smoke baffle 11 and the second smoke baffle 21 to move. For example, the driving mechanism includes a servo motor and a connecting rod, and the connecting rod is connected to the first smoke baffle 11 and the second smoke baffle 21. The servo motor is used to drive the connecting rod to move to drive the first smoke baffle 11 and the second smoke baffle 21 to move and realize the opening or closing of the first air inlet 1 and the second air inlet 2. Similarly, the driving mechanism may also be a cylinder, and the moving end of the cylinder is connected to the first smoke baffle 11 and the second smoke baffle 21. The cylinder is turned on to drive the first smoke baffle 11 and the second smoke baffle 21 to move and realize the opening or closing of the first air inlet 1 and the second air inlet 2. The driving mechanism is electrically connected to the control panel, and the first smoke baffle 11 and the second smoke baffle 21 are hinged to the range hood away from the edge of the stove 5. The first smoke baffle 11 and the second smoke baffle 21 open or close the first air inlet 1 and the second air inlet 2 through the driving mechanism. By setting the first smoke baffle 11 and the second smoke baffle 21, when the first smoke baffle 11 is opened, a guide area 8 is formed with the first air inlet 1. Similarly, when the second smoke baffle 21 is opened, a guide area 8 can also be formed with the second air inlet 2, so as to guide the oil smoke in the projection direction of the cooker 4, improve the oil smoke adsorption effect of the first air inlet 1 and the second air inlet 2, reduce the escape of oil smoke, and realize automatic opening when electrically connected to the control panel, with a higher degree of intelligence. In this embodiment, the distance sensor 3 is electrically connected to the control board to transmit the height signal of the cooker 4 identified by the distance sensor 3 to the control board, and the control board opens the air inlet that matches the height of the cooker 4 accordingly. For example, when the height of the cooker 4 is lower than the height of the second air inlet 2 and higher than the height of the first air inlet 1, the control board opens the second air inlet 2 and closes the first air inlet 1, and the user can use the cooker 4 with a higher height, such as a steamer; when the height of the cooker 4 is lower than the height of the first air inlet 1, the control board opens the first air inlet 1 and closes the second air inlet 2, and the user can use the cooker 4 with a lower height, such as a frying pan, a frying pan or a wok; when the height of the cooker 4 is higher than the height of the second air inlet 2, the control board closes the first air inlet 1 and the second air inlet 2, and outputs an interference signal through the distance sensor 3. By sending the interference signal, the user is prompted to replace the cooker 4 in time to avoid the interference between the cooker 4 and the range hood and the inability to effectively absorb the oil fume, thereby improving the actual user experience.

[0052] In another embodiment, the distance measuring sensor 3 can also be electrically connected to a buzzer or a sound and light alarm in the prior art, so that an interference signal is emitted by the distance measuring sensor 3 and transmitted to the buzzer or the sound and light alarm, so as to convert the signal transmission method into a more intuitive sound prompt or visual prompt, so that the user can react in time and replace the cooker 4.

[0053] In this embodiment, the first smoke deflector 11 has the same shape as the first air inlet 1 and the size of the first smoke deflector 11 is greater than or equal to the size of the first air inlet 1, and the second smoke deflector 21 has the same shape as the second air inlet 2 and the size of the second smoke deflector 21 is greater than or equal to the size of the second air inlet 2.

[0054] Specifically, the first air inlet 1 and the second air inlet 2 are rectangular holes, and the first smoke baffle 11 and the second smoke baffle 21 can seal the first air inlet 1 and the second air inlet 2 when closed, so as to effectively close the first air inlet 1 and the second air inlet 2 and ensure the sealing of the first air inlet 1 or the second air inlet 2.

[0055] In this embodiment, the size of the first air inlet 1 is larger than that of the second air inlet 2. When the cooker 4 with a relatively low height generates large oil smoke during frying, deep-frying, stir-frying, etc., the oil smoke can be effectively removed by increasing the size of the air inlet.

[0056] Among them, the edge of the first smoke baffle 11 on one side facing the stove 5 is at a height H1 from the top surface of the stove 5, and the edge of the second smoke baffle 21 on one side facing the stove 5 is at a height H2 from the top surface of the stove 5. The value range of H1 is 350mm≤H1≤400mm, so as to prevent the first smoke baffle 11 from being too close to the stove 5 and diverting the fire of the stove 5 to the first air inlet 1 of the range hood. In addition, through the size range of H1, the large amount of oil smoke generated by the cooking utensils 4 with lower height can be effectively extracted in time when frying, deep-frying, stir-frying and other cooking methods that generate large amounts of oil smoke.

[0057] In this embodiment, the distance between the edge of the second smoke baffle 21 facing the stove top 5 and the edge of the first smoke baffle 11 away from the stove top 5 is 50-150 mm.

[0058] Specifically, the height difference between the first smoke baffle 11 and the second smoke baffle 21 along the projection direction of the cooker 4 is H3, wherein the value range of H3 is 50mm≤H3≤150mm, and the height of H3 refers to the distance between the edge of the second smoke baffle 21 facing the stove 5 and the edge of the first smoke baffle 11 away from the stove 5. The above range of H3 allows the user to use a cooker 4 with a higher height, such as a steamer, when the steamer is just higher than the first smoke baffle 11, the first smoke baffle 11 closes the first air inlet 1 and sets the range of H3 so that the steam generated by the steamer can be effectively guided into the second air inlet 2 through the second smoke baffle 21, thereby enhancing the steam extraction effect. In addition, setting the height difference between the first smoke baffle 11 and the second smoke baffle 21 along the projection direction of the cooker 4 to 50-150mm can make the appearance of the range hood have a certain degree of recognition and be more beautiful, so that users can distinguish it from other range hoods at a glance. Furthermore, for commonly used steamers and cookers on the market, the above range can cover most of the cookers 4, so that the range of application of the range hood is wider.

[0059] Meanwhile, in the present embodiment, the dimension of the first smoke baffle 11 along the projection direction of the cooker 4 is D, and the value range of D is 200mm≤D≤250mm, so that the large amount of oil smoke generated by stir-frying can be blocked and sucked into the first air inlet 1 by the dimension of the first smoke baffle 11, and the dimension of the second smoke baffle 21 along the projection direction of the cooker 4 is d, and the value range of d is 150mm≤d≤200mm, so that the steam generated by the cooker 4 with a high height, such as a steamer, can be drawn away by the dimension of the second smoke baffle 21. It can be understood that since the dimension of the second air inlet 2 is smaller than that of the first air inlet 1, in order to ensure the effective suction of steam, the suction force at the second air inlet 2 can be appropriately enhanced to effectively absorb the steam.

[0060] In this embodiment, the range hood further includes a lower shell 6 , in which a smoke guiding cavity 61 is provided. The first air inlet 1 and the second air inlet 2 are both arranged on the lower shell 6 and communicated with the smoke guiding cavity 61 .

[0061] Specifically, the lower shell 6 is a rectangular structure and has a smoke guide cavity 61 inside. The first air inlet 1 and the second air inlet 2 are both arranged on the lower shell 6 and at different heights of the lower shell 6. In addition, the first smoke baffle 11 and the second smoke baffle 21 are both hinged on the lower shell 6. The first air inlet 1 and the second air inlet 2 are connected to the smoke guide cavity 61 in sequence, and oil smoke and steam are discharged through the smoke guide cavity 61.

[0062] Furthermore, the lower housing 6 extends toward the stove 5 , and the lower housing 6 is located at a side of the stove 5 along the projection direction.

[0063] Specifically, the lower shell 6 is located on the side of the stove 5, and correspondingly, the first air inlet 1 and the second air inlet 2 are located on the side of the stove 5 along the projection direction, so that the lower shell 6 is extended toward the stove 5 to form a low-absorption range hood. The low-absorption range hood quickly extracts oil smoke by being closer to the cooker 4 along the height direction of the stove 5 to prevent the oil smoke from escaping.

[0064] In this embodiment, the range hood further includes a fan mechanism 7 , which is disposed on a side of the lower housing 6 away from the stove 5 . The fan mechanism 7 has an air outlet 71 , and the fan mechanism 7 is connected to the smoke guide cavity 61 .

[0065] Specifically, the fan mechanism 7 is located above the lower housing 6, and the fan mechanism 7 is connected to the smoke guide cavity 61. The fan mechanism 7 includes an air outlet 71 and a centrifugal fan in the prior art, so that when the centrifugal fan is turned on, the oil smoke and steam are adsorbed according to the opened first air inlet 1 or the second air inlet 2, and the adsorbed oil smoke and steam flow from the smoke guide cavity 61 to the air outlet 71 and are finally discharged. The fan mechanism 7 can be detachably connected to the lower housing 6, for example, by a bolt assembly or a buckle structure in the prior art, so as to improve the maintenance convenience of the range hood.

[0066] In this embodiment, the distance measuring sensor 3 is arranged between the second air inlet 2 and the fan mechanism 7 .

[0067] Specifically, the distance measuring sensor 3 is arranged along the projection direction of the stove 5 and is located above the second air inlet 2, and the distance measuring sensor 3 is arranged between the second air inlet 2 and the fan mechanism 7. Compared with setting the distance measuring sensor 3 on the fan mechanism 7, on the one hand, the influence of the vibration of the fan mechanism 7 on the distance measuring accuracy is avoided when the fan mechanism 7 is working. On the other hand, the distance measuring sensor 3 is closer to the cooker 4 on the stove 5, the time required for distance measurement is correspondingly reduced, and the response is faster.

[0068] In this embodiment, the length of the first air inlet 1 is greater than or equal to the length of two cookers 4 arranged side by side along the length direction of the stove 5. By increasing the width of the first air inlet 1, multiple cookers 4 can be effectively covered and oil smoke can be absorbed when multiple cookers 4 are used at the same time.

[0069] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
