Description

Technical Field

[0001] The utility model relates to the field of kitchenware, in particular to a range hood. Background Art

[0002] At present, range hoods have been widely used by users to absorb oil smoke when cooking. The range hood usually includes a fan system located at the top and a hood lower chamber body located at the bottom, and an air inlet is arranged on the hood lower chamber body. Among them, the air inlet of the close-suction range hood generally faces the user. With such a setting, on the one hand, the placement and structure of the close-suction range hood are not easy to adjust or distribute the left and right air volumes, and the flexibility is poor, which is not easy to meet the user's usage needs; on the other hand, in the left and right directions, the negative difference generated by the range hood is small, and the oil smoke is easy to escape to both sides, affecting the oil smoke extraction effect. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a range hood to overcome the defects of the prior art range hoods, such as poor flexibility in use and difficulty in meeting user needs due to difficulty in adjusting or distributing the air volume on the left and right sides.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] A range hood, comprising a range hood lower chamber body and a fan system, the range hood further comprising two smoke baffles, the two smoke baffles being located at both sides of the range hood lower chamber body in a horizontal direction, and the smoke baffles being connected to one end of the range hood lower chamber body close to the fan system;

[0006] A first air inlet connected to the interior of the range hood lower chamber body is provided at the position where the range hood lower chamber body and the two smoke baffles are connected;

[0007] Any one of the smoke shields can be switched between an open state and a closed state, and the two smoke shields are independent of each other, so that the state adjustment of any one of the smoke shields is independent of the other smoke shield;

[0008] Wherein, when the smoke baffle is in the open state, the smoke baffle is unfolded relative to the main body of the range hood lower chamber and forms an unfolding angle, and the unfolding angle is adjustable so that the opening size of the first air inlet can be adjusted;

[0009] When the smoke baffle is in the closed state, the smoke baffle is attached to the lower chamber body of the range hood, and the first air inlet is in a closed state.

[0010] In this solution, smoke baffles that can be opened or closed according to actual needs are provided on both sides of the main body of the lower chamber of the range hood. The two smoke baffles are independently controlled, so that the smoke baffles on both sides can be in an open state or a closed state at the same time according to actual needs, or one of the smoke baffles can be in an open state and the other in a closed state. In addition, when the smoke baffle is in an open state, it can also have multiple expansion angles, which is equivalent to the smoke baffle having multiple opening positions, so that the smoke baffle can be set at different smoke blocking positions according to actual needs, and accordingly, smoke collection areas of different sizes can be formed. Therefore, the above-mentioned structural setting can flexibly adjust or distribute the air intake on the left and right sides, which is more flexible to use and can meet the various usage needs of users.

[0011] Preferably, the smoke baffle is pivotally connected to the lower cavity of the range hood;

[0012] And / or, the deployment angle is not greater than 90°.

[0013] In this solution, the above-mentioned structural setting is adopted to realize the connection between the smoke baffle and the main body of the lower chamber of the range hood through a pivot connection. The structure is simple, and the position adjustment of the smoke baffle is convenient, and the use is more flexible. In addition, the unfolding angle is not greater than 90°, which is conducive to ensuring the smoke collection effect of the smoke baffle. If the unfolding angle is greater than 90°, the oil smoke is easy to escape, affecting the oil smoke extraction effect of the range hood.

[0014] Preferably, when the smoke baffle is in a closed state, along the extension direction of the smoke baffle, the smoke baffle extends out of one end of the range hood lower chamber main body away from the fan system.

[0015] In the present solution, the above-mentioned structural setting is adopted, and the length of the smoke baffle along the extension direction is longer, so that when the smoke baffle is in the open state, it can cover a larger area, thereby forming a larger smoke collection area, which can greatly reduce or prevent the escape of oil smoke, and is beneficial to ensure the oil smoke absorption effect of the range hood.

[0016] Preferably, the length of the smoke baffle extending out of the range hood lower chamber body is in the range of 30-60 mm.

[0017] In this solution, the above-mentioned structural setting can ensure that the range hood has a better oil fume extraction effect while ensuring the user experience. If the length of the smoke baffle is too small, when the smoke baffle is in the open state, some oil fume will easily escape, which will easily affect the oil fume extraction effect of the range hood; if the length of the smoke baffle is too large, when the smoke baffle is in the closed state, the extended smoke baffle will occupy more space under the main body of the range hood lower chamber, which will easily affect the user's normal operating space and the user experience.

[0018] Preferably, the range hood lower chamber body is vertically arranged, the vertical direction is the height direction of the range hood lower chamber body, the horizontal direction is the width direction of the range hood lower chamber body, and the depth direction of the range hood lower chamber body is perpendicular to the height direction and the width direction; the height of the range hood lower chamber body is not greater than 350mm, so that the distance between the end surface of the range hood lower chamber body away from the fan system and the stove top is 400-500mm; the width of the range hood lower chamber body is not greater than 150mm, and the depth of the range hood lower chamber body is not greater than 300mm.

[0019] In this solution, the above-mentioned structure is adopted, and the size of the hood lower chamber body is such that the hood lower chamber body does not occupy the normal operating space of the user when cooking. In addition, compared with the existing range hoods, the volume of the hood lower chamber body of the range hood in this solution is smaller, which is also conducive to achieving the lightweight of the range hood.

[0020] Preferably, a second air inlet is provided at one end of the range hood lower chamber body away from the fan system, and an air duct connected to the second air inlet is provided inside the range hood lower chamber body, and the second air inlet is in a constantly open state;

[0021] When the smoke baffle is in an open state, the outlet end of the air duct along the air inlet direction is connected to the first air inlet.

[0022] In this solution, the above-mentioned structure is adopted, and the second air inlet and the corresponding air duct are arranged, so that when the smoke baffle is in the open state, air can be taken in from both the first air inlet and the second air inlet, and the outlet end of the air duct of the second air inlet can suck the smoke entering from the first air inlet, thereby improving the oil fume extraction effect of the range hood. In addition, when the smoke baffles on both sides are in the closed state, air can also be taken in from the second air inlet, thereby achieving oil fume extraction, which is convenient for users to use when cooking with very little oil fume, and further ensures the flexibility of use.

[0023] Preferably, the air duct is arranged in a tapered manner along the air inlet direction.

[0024] In the present embodiment, the above-mentioned structure is adopted. When at the outlet end of the air duct corresponding to the second air inlet or near the outlet end, the wind speed is relatively large, thereby being able to improve the suction effect of the smoke entering from the first air inlet, thereby being able to further improve or guarantee the smoke suction effect of the range hood.

[0025] Preferably, two groups of the second air inlets are provided, and the two groups of the second air inlets are provided in a one-to-one correspondence with the two smoke baffles, and there are two air ducts, and the two air ducts are provided in a one-to-one correspondence with the two groups of the second air inlets.

[0026] In this solution, the above-mentioned structure is adopted, and the two sets of second air inlets can be used to respectively draw in the smoke entering from the corresponding first air inlets, which is conducive to ensuring the entrainment effect, and further conducive to further improving or ensuring the oil fume extraction effect of the range hood. In addition, when the smoke baffles on both sides are in a closed state, the two sets of second air inlets can also achieve a better oil fume extraction effect.

[0027] Preferably, the two air ducts are surrounded by a partition plate and the wall surface of the main body of the lower chamber of the range hood;

[0028] And / or, the inclination angle formed by the wall surface of the air duct and the vertical surface is not less than 2°.

[0029] In this solution, the above structure can ensure a better ventilation rate and thus a better fume extraction effect. If the inclination angle is too small, a low-speed vortex is likely to exist at the outlet of the air duct and block the air inlet, resulting in a loss of ventilation efficiency and thus affecting the fume extraction effect.

[0030] Preferably, when the two smoke baffles are at the maximum deployment angle, the two smoke baffles are symmetrically arranged on both sides of the lower chamber body of the range hood;

[0031] In this solution, the above-mentioned structural setting is adopted, which is not only beautiful, but also can conveniently and reliably achieve this requirement when the user wants the air intake on the left and right sides to be uniform. In addition, the smoke shields on both sides are symmetrically arranged. When installing the smoke shields and the main body of the lower chamber of the range hood, the smoke shields can be selected at will, and there is no need to identify a specific smoke shield, which facilitates the installation of the smoke shields and the main body of the lower chamber of the range hood.

[0032] And / or, one end of the smoke baffle connected to the lower chamber body of the range hood is a connecting end, and the other end is a non-connecting end, and the non-connecting end is an arc-shaped structure.

[0033] In this solution, the above-mentioned structural setting is adopted, and the non-connecting end of the smoke shield is set as an arc structure, which is beneficial to prevent users from accidentally touching the smoke shield and causing accidental injuries to the users or damage to the smoke shield, thereby ensuring overall safety.

[0034] The positive and progressive effects of the utility model are:

[0035] In the range hood, smoke baffles that can be opened or closed according to actual needs are provided on both sides of the main body of the lower chamber of the range hood. The two smoke baffles are independently controlled, so that the smoke baffles on both sides can be in an open state or a closed state at the same time according to actual needs, or one of the smoke baffles can be in an open state and the other in a closed state. In addition, when the smoke baffle is in an open state, it can also have multiple deployment angles, which is equivalent to the smoke baffle having multiple opening positions, so that the smoke baffle can be set at different smoke blocking positions according to actual needs, and accordingly, smoke collection areas of different sizes can be formed. Therefore, the range hood can flexibly adjust or distribute the air intake on the left and right sides, is more flexible to use, and can meet the various usage needs of users.

[0053] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0054] like Figures 1 to 4 As shown, this embodiment provides a range hood, which includes a range hood lower chamber body 10 and a fan system 20, and the range hood further includes two smoke baffles 30, which are located on both sides of the range hood lower chamber body 10 in the horizontal direction, and the smoke baffles 30 are connected to one end of the range hood lower chamber body 10 close to the fan system 20. A first air inlet 40 connected to the interior of the range hood lower chamber body 10 is provided at the position where the range hood lower chamber body 10 is connected to the two smoke baffles 30. Any smoke baffle 30 can be switched between an open state and a closed state, and the two smoke baffles 30 are independent of each other, so that the state adjustment of any smoke baffle 30 is independent of the other smoke baffle 30. Wherein, when the smoke baffle 30 is in the open state, the smoke baffle 30 is unfolded relative to the range hood lower chamber body 10 and forms an unfolding angle, and the unfolding angle is adjustable, so that the opening size of the first air inlet 40 can be adjusted. When the smoke baffle 30 is in a closed state, the smoke baffle 30 is attached to the range hood lower chamber body 10, and the first air inlet 40 is in a closed state.

[0055] In this embodiment, smoke baffles 30 that can be opened or closed according to actual needs are provided on both sides of the main body 10 of the lower chamber of the range hood. The two smoke baffles 30 are independently controlled, so that the smoke baffles 30 on both sides can be in an open state or a closed state at the same time according to actual needs, or one of the smoke baffles 30 can be in an open state and the other in a closed state. In addition, when the smoke baffle 30 is in an open state, it can also have multiple deployment angles, which is equivalent to the smoke baffle 30 having multiple opening positions, so that the smoke baffle 30 can be set at different smoke blocking positions according to actual needs, and accordingly, different sizes of smoke collection areas can be formed. Therefore, the above-mentioned structural setting can flexibly adjust or distribute the air intake on the left and right sides, which is more flexible to use and can meet the various usage needs of users.

[0056] Figure 1 Schematic diagrams of the smoke baffle 30 in the open state and the closed state are shown in FIG. 1 , wherein the dotted line portion illustrates the positional relationship between the smoke baffle 30 and the range hood lower chamber body 10 when the smoke baffle 30 is in the closed state.

[0057] It should be noted that, in the present embodiment, the connection method between the smoke baffle 30 and the lower chamber body 10 of the range hood is not specifically limited, and a connection method or structure suitable for this purpose according to the existing technology can be adopted, such as a connection structure of a window that can be opened at different angles.

[0058] As a preferred arrangement, in this embodiment, the smoke baffle 30 is pivotally connected to the lower cavity of the range hood, so that the smoke baffle 30 can be in different open positions relative to the lower cavity of the range hood, and can be locked in the corresponding open position as required, and can be unlocked from the open position when it needs to be adjusted again. Among them, the connection between the smoke baffle 30 and the lower cavity body 10 of the range hood is realized by pivoting, which has a simple structure, facilitates the position adjustment of the smoke baffle 30, and is more flexible to use.

[0059] In this embodiment, there is no specific limitation on the expansion angle that the smoke baffle 30 and the hood lower chamber body 10 can form, as long as the smoke absorption effect can be achieved.

[0060] As a preferred arrangement, in this embodiment, the expansion angle is set to be no greater than 90°. This arrangement is conducive to ensuring the smoke trapping effect of the smoke baffle 30. If the expansion angle is greater than 90°, the smoke will easily escape, affecting the smoke absorbing effect of the range hood.

[0061] In this embodiment, there is no restriction on the specific shape of the smoke baffle 30. As a preferred setting method, in order to enable the smoke baffle 30 to fit more reliably with the range hood lower chamber body 10, the side of the smoke baffle 30 that fits with the range hood lower chamber body 10 can be set to adapt to the side wall of the range hood lower chamber body 10.

[0062] In addition, it should be noted that the adjustment of the state of the smoke baffle 30 can be achieved through manual operation by the user or automatically through a driving mechanism. As for the specific implementation method, it is well known to those skilled in the art and will not be described in detail here.

[0063] Furthermore, if Figure 1 As shown, when the smoke baffle 30 is in the closed state, along the extension direction of the smoke baffle 30, the smoke baffle 30 extends out of the end of the range hood lower chamber body 10 away from the fan system 20. In this way, the smoke baffle 30 has a longer length along the extension direction, so that when the smoke baffle 30 is in the open state, it can cover a larger range, thereby forming a larger smoke collection area, which can reduce or prevent the escape of oil smoke to a large extent, thereby facilitating the oil smoke absorption effect of the range hood.

[0064] As a preferred setting, the length of the smoke baffle 30 extending out of the range hood lower chamber body 10 is in the range of 30-60mm. With such a setting, the range hood can have a better oil fume absorbing effect while ensuring the user experience. If the length of the smoke baffle 30 extending out is too small, when the smoke baffle 30 is in the open state, some oil fume will easily escape, which will easily affect the oil fume absorbing effect of the range hood; if the length of the smoke baffle 30 extending out is too large, when the smoke baffle 30 is in the closed state, the extended smoke baffle 30 will occupy more space under the range hood lower chamber body 10, which will easily affect the user's normal operating space and the user experience.

[0065] Reference Figure 2 and Figure 3 It is understood that the hood lower cavity body 10 is vertically arranged, the vertical direction is the height direction of the hood lower cavity body 10, the horizontal direction is the width direction of the hood lower cavity body 10, and the depth direction of the hood lower cavity body 10 is perpendicular to the height direction and the width direction; the height H of the hood lower cavity body 10 is not greater than 350mm, so that the distance between the end surface of the hood lower cavity body 10 away from the fan system 20 and the stove top is 400-500mm; the width W of the hood lower cavity body 10 is not greater than 150mm, and the depth D of the hood lower cavity body 10 is not greater than 300mm.

[0066] With the above arrangement, the size of the range hood lower chamber body 10 does not occupy the normal operating space of the user when cooking. In addition, compared with the existing range hoods, the range hood lower chamber body 10 of the range hood in this solution is smaller in volume, which is also conducive to achieving lightweight range hoods.

[0067] like Figure 1 and Figure 4 As shown, a second air inlet 50 is provided at one end of the range hood lower chamber body 10 away from the fan system 20, and an air duct 60 is provided inside the range hood lower chamber body 10, which is connected to the second air inlet 50, and the second air inlet 50 is in a constant open state. When the smoke baffle 30 is in an open state, the outlet end of the air duct 60 along the air inlet direction is connected to the first air inlet 40. By providing the second air inlet 50 and the corresponding air duct 60, when the smoke baffle 30 is in an open state, air can be taken in from both the first air inlet 40 and the second air inlet 50, and the outlet end of the air duct 60 of the second air inlet 50 can roll up and suck the smoke entering from the first air inlet 40, thereby improving the oil smoke absorbing effect of the range hood. In addition, when the smoke baffles 30 on both sides are in a closed state, air can also be taken in from the second air inlet 50, thereby realizing oil smoke absorption, which is convenient for users to use when cooking with very little oil smoke, and further ensures the flexibility of use.

[0068] It should be noted that the second air inlet 50 is in a constant open state to illustrate that whether the smoke shield 30 is in an open state or not does not affect the normal use of the second air inlet 50. That is to say, even if the smoke shield 30 is in a closed state, the smoke shield 30 will not block the second air inlet 50. Accordingly, the second air inlet 50 is located outside the area on the range hood lower chamber body 10 where the smoke shield 30 is attached.

[0069] like Figure 4 As shown, the air duct 60 is arranged in a tapered manner along the air inlet direction. With such arrangement, the wind speed is relatively high at the outlet end of the air duct 60 corresponding to the second air inlet 50 or near the outlet end, thereby improving the suction effect of the smoke entering from the first air inlet 40, thereby further improving or ensuring the smoke suction effect of the range hood.

[0070] Furthermore, two groups of second air inlets 50 are provided, and the two groups of second air inlets 50 are provided in one-to-one correspondence with the two smoke baffles 30, and there are two air ducts 60, and the two air ducts 60 are provided in one-to-one correspondence with the two groups of second air inlets 50. Among them, the two groups of second air inlets 50 can be used to respectively suck the smoke entering from the corresponding first air inlet 40, which is conducive to ensuring the suction effect, and further helps to further improve or ensure the oil fume extraction effect of the range hood. In addition, when the smoke baffles 30 on both sides are in a closed state, the two groups of second air inlets 50 can also achieve a better oil fume extraction effect. Figure 2 Schematically shows the flow path when one of the smoke baffles 30 is in an open state, referred to as the first air inlet flow path P1, and also shows the flow path entering from the second air inlet 50, referred to as the second air inlet flow path P2.

[0071] It should be noted that the specific number of each group of second air inlets 50 is not specifically limited and can be set according to actual needs. Correspondingly, the number of the aforementioned first air inlets 40 is also not specifically limited.

[0072] Reference Figure 4 It is understood that the two air ducts 60 are surrounded by the partition and the wall of the lower chamber body 10 of the range hood. Alternatively or preferably, the inclination angle formed by the wall of the air duct 60 and the vertical plane is not less than 2°. Adopting this inclination angle range can ensure a better ventilation rate, make ventilation smooth, and thus ensure a better oil fume extraction effect. If the inclination angle is too small, low-speed vortices are likely to exist at the outlet end of the air duct 60 and block the air inlet, resulting in a loss of ventilation efficiency, thereby affecting the oil fume extraction effect.

[0073] Combination Figures 1 to 4It is understood that when the two smoke baffles 30 are at the maximum deployment angle, the two smoke baffles 30 are symmetrically arranged on both sides of the range hood lower chamber body 10. Such an arrangement is both aesthetically pleasing and can more conveniently and reliably achieve this requirement when the user wants the air intake on the left and right sides to be uniform. In addition, the smoke baffles 30 on both sides are symmetrically arranged. When installing the smoke baffles 30 and the range hood lower chamber body 10, the smoke baffles 30 can be selected at will, and there is no need to identify a specific smoke baffle 30, which facilitates the installation of the smoke baffles 30 and the range hood lower chamber body 10.

[0074] In addition, if Figures 1 to 4 As shown, one end of the smoke shield 30 connected to the lower chamber body 10 of the range hood is a connection end, and the other end is a non-connection end, and the non-connection end is an arc structure 301. The non-connection end of the smoke shield 30 is set as an arc structure 301, which is conducive to preventing users from accidentally touching the smoke shield 30 and causing accidental injuries to the user or damage to the smoke shield 30, thereby ensuring overall safety.

[0075] Furthermore, refer to Figure 1 It is understood that when the smoke baffles 30 on both sides are in the closed state, the arc structures 301 of the two smoke baffles 30 can be arranged to be engaged with each other. Such an arrangement can further improve the overall safety.

[0076] In summary, for the range hood, both sides of the lower chamber body 10 of the range hood are provided with smoke baffles 30 that can be opened or closed according to actual needs. The two smoke baffles 30 are independently controlled, so that the smoke baffles 30 on both sides can be in an open state or a closed state at the same time according to actual needs, or one of the smoke baffles 30 can be in an open state and the other in a closed state. In addition, when the smoke baffle 30 is in an open state, it can also have multiple deployment angles, which is equivalent to the smoke baffle 30 having multiple opening positions, so that the smoke baffle 30 can be set at different smoke blocking positions according to actual needs, and accordingly, smoke collection areas of different sizes can be formed. Therefore, the range hood can flexibly adjust or distribute the air intake on the left and right, is more flexible to use, and can meet the various usage needs of users. In addition, the specific structural setting of the smoke baffle 30 can ensure the overall safety of the range hood on the basis of ensuring the oil fume suction effect of the range hood.
