Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a side-suction range hood. Background Technology

[0002] Range hoods have become an indispensable kitchen appliance in modern homes. A range hood uses a fan installed inside to draw in and exhaust cooking fumes. When the impeller rotates, a negative pressure is generated at the center of the fan, drawing the fumes from the smoke collection hood into the fan, where they are then accelerated and expelled outdoors. Side-draft range hoods typically have a smoke inlet on the front panel of the smoke collection hood, along with a control panel for opening and closing the inlet. However, in some designs, the control panel usually opens outwards from the smoke inlet, causing grease to drip onto the stovetop or cooking utensils, affecting the user experience. Utility Model Content

[0003] The main purpose of this invention is to propose a side-suction range hood, which aims to reduce the probability of oil dripping onto the stove or cooking utensils and improve the user experience.

[0004] To achieve the above objectives, the side-suction range hood proposed in this utility model includes: A smoke hood, comprising a smoke collection chamber and an upper smoke inlet communicating with the smoke collection chamber; and The upper smoke inlet panel is movably connected relative to the smoke collection hood, so as to have a closed state that covers the upper smoke inlet and an open state that opens the upper smoke inlet; in the open state, the upper smoke inlet panel is located inside the smoke collection chamber.

[0005] Optionally, in the open state, there is a gap between the upper edge and the lower edge of the upper smoke inlet panel and the upper smoke inlet.

[0006] Optionally, in the open state, the upper smoke inlet panel is tilted from bottom to top in a direction away from the upper smoke inlet.

[0007] Optionally, the upper smoke inlet panel is rotatably connected relative to the smoke collection hood.

[0008] Optionally, the side-suction range hood further includes a rotating arm, the upper smoke inlet panel is fixedly connected to the upper end of the rotating arm, the lower end of the rotating arm is rotatably connected to the smoke collection hood, and the rotating connection point of the rotating arm is located below the upper smoke inlet.

[0009] Optionally, the side-suction range hood further includes an adapter plate, which includes a first plate portion and a second plate portion that are bent and connected together. The first plate portion is fixedly connected to the back side of the upper smoke inlet panel, and the second plate portion is fixedly connected to the upper end of the rotating arm.

[0010] Optionally, the side-suction range hood further includes a drive device disposed within the smoke collection hood. The drive device includes a power component and a transmission mechanism. The power component drives the upper smoke inlet panel to open and close through the transmission mechanism.

[0011] Optionally, the transmission mechanism is configured as a linkage mechanism.

[0012] Optionally, the linkage mechanism includes a first link and a second link rotatably connected to each other. The end of the first link away from the second link is rotatably connected to the power component, and the end of the second link away from the first link is used to drive the upper smoke inlet panel to open and close.

[0013] Optionally, a limiting mechanism is provided between the transmission mechanism and the smoke collection hood to limit the maximum position of the upper smoke inlet panel.

[0014] Optionally, the limiting mechanism includes a first limiting part disposed on the smoke collection hood. In the closed state, the transmission mechanism is limited in engagement with the first limiting part, thereby restricting the outward rotation of the upper smoke inlet panel relative to the upper smoke inlet; and / or The limiting mechanism includes a second limiting part disposed on the smoke collection hood. When the transmission mechanism is engaged with the second limiting part, the inward rotation of the upper smoke inlet panel relative to the upper smoke inlet is restricted.

[0015] Optionally, the smoke collection hood is provided with an isolation cover, and the power component is installed inside the isolation cover.

[0016] In this invention, the top-mounted smoke inlet panel moves towards the smoke collection chamber during the transition from the closed to the open state. This ensures that the panel is located within the smoke collection chamber in the open state. Consequently, even if grease drips from the panel, it will only fall into the smoke collection chamber, preventing it from dripping onto the stovetop or cooking appliances and improving the user experience. Furthermore, the top-mounted smoke inlet is typically positioned near the top of the smoke hood. Therefore, even if the side-suction range hood is a slim, lightweight design close to the smoke source, and the user is using tall cooking appliances such as multi-layer steamers with high smoke outlets, the high-level fumes can still be drawn out by the open top-mounted smoke inlet, reducing smoke leakage.

[0023] This utility model proposes a side-suction range hood.

[0024] Reference Figures 1 to 3 In one embodiment of this utility model, the side-suction range hood includes: The smoke hood 1 has a smoke collection chamber 101 and an upper smoke inlet 105 communicating with the smoke collection chamber 101; and The upper smoke inlet panel 104 is movably connected to the smoke collection hood 1 so as to have a closed state that covers the upper smoke inlet 105 and an open state that opens the upper smoke inlet 105; in the open state, the upper smoke inlet panel 104 is located inside the smoke collection chamber 101.

[0025] In this embodiment, the smoke hood 1 typically also has a lower smoke inlet 102 located below the upper smoke inlet 105, and the lower smoke inlet 102 typically has a lower opening and closing mechanism 12 to control the opening and closing state of the lower smoke inlet 102. Here, the opening and closing state refers not only to the open and closed states, but also to different degrees of opening in the open state. Optionally, the lower smoke inlet 102 has a smoke inlet groove recessed into the smoke collection chamber 101, and the smoke inlet groove has a smoke passage communicating with the smoke collection chamber 101. The lower opening and closing mechanism 12 is located at the smoke passage. Thus, even if oil droplets fall from the lower opening and closing mechanism 12, they will only drip into the smoke inlet groove or the smoke collection chamber 101, and will not drip onto the stove or cooking utensils, thereby improving the user experience. Optionally, the smoke inlet is located on the upper wall of the smoke inlet groove 11, and the lower opening and closing mechanism 12 is located on the upper side of the smoke inlet, that is, on the top side of the smoke inlet groove. This makes it virtually impossible for the user to see the lower opening and closing mechanism 12 even when passing through the lower smoke inlet 102, thus hiding the lower opening and closing mechanism 12. Oil stains on the lower opening and closing mechanism 12 will not be visible to the user, further improving the user experience. Of course, in the technical solution of this utility model, it is not necessary to limit the smoke hood 1 to simultaneously having a lower smoke inlet 102. In some embodiments, the smoke hood 1 may only have an upper smoke inlet 105, which is usually located near the upper end of the smoke hood 1.

[0026] The smoke hood 1 typically includes a back panel 132 and a front panel 131 opposite to the back panel 132, with the front panel 131 being inclined. Side-draft range hoods typically include slim side-draft range hoods and traditional side-draft range hoods.

[0027] For traditional side-suction range hoods, the smoke collection hood 1 is triangular in shape when viewed from the side, with the lower smoke inlet 102 and the upper smoke inlet 105 both located on the front panel 131.

[0028] For slim side-draft range hoods, the upper part of the front panel 131 extends obliquely to the middle or rear part of the top plate of the smoke collection hood 1. The smoke collection hood 1 is arranged in a near "7" shape when viewed from the side (see reference). Figure 2 Thus, the smoke hood 1 can be closer to the smoke source, shortening the smoke extraction path and improving smoke-locking efficiency during stir-frying. For slim side-suction range hoods, both the lower smoke inlet 102 and the upper smoke inlet 105 are located on the front panel 131. Optionally, the angle between the front panel 131 and the back panel 132 ranges from 10° to 30°, thus making the front panel 131 relatively vertical to reduce the space occupied by the smoke hood 1 in the user's operating space.

[0029] In this embodiment, the upper smoke inlet panel 104 can be opened by rotating inward or by sliding inward relative to the upper smoke inlet port 105, as long as the upper smoke inlet panel 104 moves into the smoke collection chamber 101 during the process of opening the upper smoke inlet port 105.

[0030] In this invention, the upper smoke inlet panel 104 moves towards the smoke collection chamber 101 during the transition from the closed state to the open state. This ensures that the upper smoke inlet panel 104 is located within the smoke collection chamber 101 in the open state. Consequently, even if oil stains on the upper smoke inlet panel 104 drip downwards, they will only drip into the smoke collection chamber 101, preventing them from dripping onto the stovetop or cooking appliances and improving the user experience. Furthermore, the upper smoke inlet 105 is typically positioned near the upper end of the smoke hood 1. Therefore, even if the side-suction range hood is a slim, lightweight type close to the smoke source, and the user is using tall cooking appliances such as multi-layer steamers with high smoke outlets, these high-level fumes can still be drawn out by the open upper smoke inlet 105, reducing smoke leakage.

[0031] It is worth mentioning that for side-suction range hoods that also have a lower smoke inlet 102, which correspond to different cooking scenarios on the two burners of a dual-burner stove, such as, but not limited to, cooking with a multi-layer steamer on the left burner, where the smoke outlet of the multi-layer steamer is higher, even higher than the lower smoke inlet 102 of the slim side-suction range hood, and cooking with a wok on the right burner, where the smoke outlet of the wok is lower; in this cooking scenario, the upper smoke inlet 105 and the lower smoke inlet 102 can be opened at the same time, so that the upper smoke inlet 105 can be used to draw away the high smoke and reduce the amount of oil fume leakage, while the lower smoke inlet 102 can be used to draw away the low smoke, that is, to achieve the vertical diversion of smoke and reduce the amount of oil fume leakage.

[0032] Furthermore, referring to Figure 3 In the open state, the upper and lower edges of the upper smoke inlet panel 104 are spaced apart from the upper smoke inlet 105. Thus, compared to the technical solution where the lower edge of the upper smoke inlet panel 104 is rotatably connected to the lower edge of the upper smoke inlet 105, the technical solution of this embodiment can better prevent oil stains from flowing from the lower edge of the upper smoke inlet 105 to the outside of the upper smoke inlet 105 through the lower edge of the upper smoke inlet panel 104.

[0033] Furthermore, in the open state, the upper smoke inlet panel 104 is tilted upwards away from the upper smoke inlet 105. This allows the upper smoke inlet panel 104 to guide the fumes upwards, directing them towards the exhaust fan of the side-suction range hood, thereby improving the efficiency of fume extraction. It is worth noting that under the suction of the exhaust fan, the fumes tend to flow upwards from the upper smoke inlet 105. In this embodiment, the upper smoke inlet panel 104 in the open state is also tilted upwards, following the same flow trend of the fumes. In other words, the upper smoke inlet panel 104 in the open state guides the flow of the fumes, better directing their flow and making the exhaust of the fumes smoother.

[0034] Furthermore, the upper smoke inlet panel 104 is rotatably connected relative to the smoke collection hood 1, so as to realize the inward rotation and opening of the upper smoke inlet panel 104 relative to the upper smoke inlet 105, so that the upper smoke inlet panel 104 is inclined in the open state, so as to reuse it as a guide plate to guide the oil fumes to the exhaust fan. In this embodiment, after the upper smoke inlet panel 104 is rotated inward and opened, it is arranged opposite to the upper smoke inlet 105 in the horizontal direction, that is, the upper smoke inlet 105 is not located below the upper smoke inlet panel 104, so that even if oil droplets on the upper smoke inlet panel 104 drip downward, they will not drip outward from the upper smoke inlet 105. However, this design is not limited to this. In other embodiments, the upper smoke inlet panel 104 can also be slidably connected to the inner side of the front panel 131 of the smoke collection hood 1, so as to realize that the upper smoke inlet panel 104 can slide and translate to the upper side or the lower side of the upper smoke inlet 105 to open the upper smoke inlet 105; or, the upper smoke inlet panel 104 can also translate inward relative to the axis of the upper smoke inlet 105 to open.

[0035] For the rotated-open upper smoke inlet panel 104, optionally, refer to Figure 3The side-suction range hood also includes a rotating arm 161. The upper smoke inlet panel 104 is fixedly connected to the upper end of the rotating arm 161, and the lower end of the rotating arm 161 is rotatably connected to the smoke collection hood 1. The rotating connection point of the rotating arm 161 is located below the upper smoke inlet 105. In this way, when the upper smoke inlet panel 104 is in the open state, there is a gap between the upper edge and the lower edge of the upper smoke inlet panel 104 and the upper smoke inlet 105. In this embodiment, two rotating arms 161 are provided, respectively located at opposite ends of the upper smoke inlet panel 104, to improve the stability of the opening and closing movement of the upper smoke inlet panel 104. Of course, in other embodiments, only one rotating arm 161 may be provided, which can also realize the rotational opening of the upper smoke inlet panel 104. In addition, in some embodiments, when the length of the upper smoke inlet panel 104 is very large, in order to avoid the middle of the upper smoke inlet panel 104 drooping, several rotating arms 161 may be added at the middle position of the upper smoke inlet panel 104, or multiple upper smoke inlet panels 104 may be arranged sequentially from left to right on the upper smoke inlet 105.

[0036] Optionally, the side-suction range hood further includes an adapter plate 162, which includes a first plate portion 162a and a second plate portion 162b that are bent and connected together. The first plate portion 162a is fixedly connected to the back side of the upper smoke inlet panel 104, and the second plate portion 162b is fixedly connected to the upper end of the rotating arm 161. In this embodiment, the first plate portion 162a and the upper smoke inlet panel 104 are connected by a plate-to-plate bonding method. This connection method has a larger connection area and higher connection stability, thereby reducing the probability of the upper smoke inlet panel 104 shaking during rotation. In this embodiment, the first plate portion 162a and the upper smoke inlet panel 104 are bonded or welded to ensure the integrity of the upper smoke inlet panel 104, thereby ensuring a good appearance of the upper smoke inlet panel 104; of course, this does not exclude the possibility that the first plate portion 162a and the upper smoke inlet panel 104 can be connected by screw fastening or riveting. Optionally, the rotating arm 161 is plate-shaped, so the second plate portion 162b and the rotating arm 161 are also connected by a plate-to-plate contact, which also has high connection stability. In this embodiment, the second plate portion 162b and the rotating arm 161 can be connected by screws or riveting for easy disassembly and maintenance; of course, this does not preclude the second plate portion 162b and the rotating arm 161 from being connected by adhesive or welding.

[0037] Furthermore, referring to Figure 2The side-suction range hood also includes a drive device 17 disposed within the smoke collection hood 1. The drive device 17 includes a power component 171 and a transmission mechanism 172. The power component 171 drives the upper smoke inlet panel 104 to open and close via the transmission mechanism 172. In this embodiment, the power component 171 indirectly drives the upper smoke inlet panel 104 via the transmission mechanism 172, which facilitates the rational selection of the installation position of the power component 171. For a technical solution with the rotating arm 161, the power component 171 is connected to the rotating arm 161 via the transmission mechanism 172. However, this design is not limited to this. In other embodiments, the drive device 17 may not have the transmission mechanism 172, and the drive shaft of the power component 171 may be directly connected to the rotation connection point of the rotating arm 161. Without loss of generality, in this embodiment, the connection position of the transmission mechanism 172 and the rotating arm 161 is usually located close to the upper end of the rotating arm 161, that is, spaced apart from the rotation connection point of the rotating arm 161, so as to facilitate the rotation of the rotating arm 161. Optionally, the power component 171 includes a drive motor 171a and a reducer 171b connected together. The output shaft of the reducer 171b is connected to the rotating arm 161 through the transmission mechanism 172. The arrangement of the reducer 171b can increase the driving torque of the power component 171.

[0038] Optionally, refer to as well. Figure 4 and Figure 5 In this embodiment, the transmission mechanism 172 is configured as a linkage mechanism, and the longer length of the linkage is more conducive to the rational selection of the installation position of the power component 171. However, this design is not limited to this; in other embodiments, the transmission mechanism 172 can also be configured as a gear mechanism, etc.

[0039] Optionally, the linkage mechanism includes a first link 172a and a second link 172b rotatably connected. The end of the first link 172a away from the second link 172b is rotatably connected to the power member 171, and the end of the second link 172b away from the first link 172a is used to drive the opening and closing of the upper smoke inlet panel 104. It can be understood that the linkage mechanism in this embodiment is a multi-link structure. Multiple links are advantageous for increasing the length, thus facilitating the rational selection of the installation position of the power member 171. In the technical solution with the rotating arm 161, the end of the second link 172b away from the first link 172a is rotatably connected to the rotating arm 161.

[0040] Furthermore, a limiting mechanism 18 is provided between the transmission mechanism 172 and the smoke collection hood 1 to limit the maximum movement of the upper smoke inlet panel 104, thereby preventing the upper smoke inlet panel 104 from continuing to rotate outward in the closed state and creating a gap between the upper smoke inlet panel 104 and the upper smoke inlet 105. This would not only affect the product's appearance but also give insects and other creatures the opportunity to enter the smoke collection chamber 101, and / or prevent the upper smoke inlet panel 104 from rotating excessively inward relative to the upper smoke inlet 105, making it difficult for the upper smoke inlet panel 104 to return to the closed state.

[0041] In one embodiment, the limiting mechanism 18 includes a first limiting part 181 disposed on the smoke collection hood 1. In the closed state, the transmission mechanism 172 engages with the first limiting part 181 to limit the outward rotation of the upper smoke inlet panel 104 relative to the upper smoke inlet 105, thereby preventing the upper smoke inlet panel 104 from continuing to rotate outward in the closed state and causing a gap between the upper smoke inlet panel 104 and the upper smoke inlet 105. For an embodiment with a first connecting rod 172a and a second connecting rod 172b, optionally, the first limiting part 181 is configured as a first limiting protrusion disposed on the side wall of the smoke collection chamber 101. A hook 172c is bent at the end of the first connecting rod 172a away from the second connecting rod 172b. In the closed state, the hook 172c overlaps and limits the first limiting protrusion, thereby limiting the outward rotation of the upper smoke inlet panel 104 relative to the upper smoke inlet 105. Optionally, the first limiting protrusion includes a mounting plate and a first limiting plate that are bent and connected together. The mounting plate is fixed to the side wall of the smoke collection chamber 101. In the closed state, the hook 172c overlaps and limits the first limiting plate.

[0042] In another embodiment, the limiting mechanism 18 includes a second limiting part 182 disposed on the smoke collection hood 1. When the transmission mechanism 172 is engaged with the second limiting part 182, the inward rotation of the upper smoke inlet panel 104 relative to the upper smoke inlet 105 is restricted, thereby preventing the upper smoke inlet panel 104 from rotating excessively inward relative to the upper smoke inlet 105, which would make it difficult for the upper smoke inlet panel 104 to return to the closed state. For the scheme with the first connecting rod 172a and the second connecting rod 172b, optionally, the second limiting part 182 is configured as a second limiting protrusion protruding inside the smoke collection cavity 101. When the first connecting rod 172a is engaged with the second limiting protrusion, the inward rotation of the upper smoke inlet panel 104 relative to the upper smoke inlet 105 is restricted.

[0043] In another embodiment, the limiting structure may also include the first limiting part 181 and the second limiting part 182, so as to prevent the upper smoke inlet panel 104 from continuing to rotate outward in the closed state and creating a gap between the upper smoke inlet panel 104 and the upper smoke inlet 105, and to prevent the upper smoke inlet panel 104 from rotating excessively inward relative to the upper smoke inlet 105, which would make it difficult for the upper smoke inlet panel 104 to return to the closed state.

[0044] In one embodiment, the fume hood 1 is provided with an isolation cover 19, and the power component 171 is installed inside the isolation cover 19. This embodiment, by adding the isolation cover 19, reduces the probability of the power component 171 being contaminated by oil fumes, thereby extending the service life of the power component 171. It can be understood that the connection structure between the power component 171 and the transmission mechanism 172 is movably inserted through the isolation cover 19; without loss of generality, the output shaft of the power component 171 is movably inserted through the isolation cover 19 to be fixedly connected to the transmission mechanism 172; for technical solutions with a first connecting rod 172a and a second connecting rod 172b, after the output shaft of the power component 171 movably passes through the isolation cover 19, it is fixedly connected to the end of the first connecting rod 172a away from the second connecting rod 172b to drive the first connecting rod 172a to rotate. Optionally, the first limiting protrusion is configured as a bent limiting plate on the isolation cover 19.

[0045] Furthermore, the side-draft range hood also includes a detection device, which is communicatively connected to the processor of the side-draft range hood. This allows the side-draft range hood to determine the amount of smoke and / or the smoke outlet position in the cooking environment based on the detection data obtained by the detection device, and then control the opening and closing state of the upper smoke inlet panel 104 based on the amount of smoke and / or the smoke outlet position. Of course, for a technical solution that also includes the lower smoke inlet 102, the opening and closing state of the lower opening and closing mechanism 12 can also be controlled based on the amount of smoke and / or the smoke outlet position. In this invention, the smoke outlet position refers to the location of the smoke point, which can include the height of the smoke outlet. It is understood that due to different stove heights, the height of the smoke outlet for the same cooking appliance will differ, or for the same stove, different cooking appliances with different heights will also result in different smoke outlet heights. It can also include the smoke outlet being located on the left or right side below the range hood. For example, for a dual-burner stove, smoke may emanate from the cooking appliance on the left burner, in which case the smoke outlet is on the left side below the range hood; or smoke may emanate from the cooking appliance on the right burner, in which case the smoke outlet is on the right side below the range hood. The lower smoke inlet 102 is provided with a left smoke inlet and a right smoke inlet, and each of the left and right smoke inlets has an independent opening and closing mechanism. The opening and closing mechanisms of the left and right smoke inlets can be controlled according to their respective smoke outlet positions.

[0046] In one embodiment, the detection device may include a ranging device (not shown), and the detection data includes height data obtained based on the ranging device. The processor of the side-suction range hood can determine the type of cooking appliance based on the height data, and then determine whether there is a smoke outlet position higher or lower than a preset height based on the type of cooking appliance.

[0047] In this embodiment, the ranging device can be configured as a ranging sensor on the front panel 131 of the smoke hood 1, and the ranging sensor can be rotated to scan the height of different positions of the cooking appliance by rotating the ranging sensor, thereby obtaining height data for characterizing the outline of the corresponding cooking appliance, and then determining the type of the corresponding cooking appliance (steamer, wok, soup pot, frying pan, etc.). It can be understood that the smoke outlet height of different types of cooking appliances is usually different. For example, the smoke outlet height of a steamer is usually higher than that of a soup pot, the smoke outlet height of a soup pot is usually higher than that of a wok, and the smoke outlet height of a wok is usually higher than that of a frying pan.

[0048] In some other embodiments, the ranging sensor may be non-rotating. In this case, multiple ranging sensors can be used, for example, forming a ranging sensor array, to measure the height of different positions of the cooking appliance. In still other embodiments, the type of cooking appliance can be determined simply by the highest detected data, without needing to characterize the outline of the cooking appliance through a series of height data. In yet another embodiment, the highest detected data can be used simply as the height of the smoke vent of the cooking appliance, without needing to first determine the type of cooking appliance and then determine the height of the smoke vent.

[0049] In another embodiment, the detection device may include a vision device, and the detection data includes image data acquired based on the vision device; the processor of the side-suction range hood can determine the type of cooking appliance based on the image data, and then determine whether there is a smoke outlet position higher or lower than a preset height based on the type of cooking appliance.

[0050] In this embodiment, the vision device includes a downward-facing camera mounted on the front panel 131 of the fume hood 1. The camera acquires actual images of the cooking utensils on the stove and matches them with pre-stored images of the cooking utensils to determine the type of the corresponding cooking utensils (steamer, wok, soup pot, frying pan, etc.). It is understood that the smoke outlet height of different types of cooking utensils is usually different. For example, the smoke outlet height of a steamer is usually higher than that of a soup pot, the smoke outlet height of a soup pot is usually higher than that of a wok, and the smoke outlet height of a wok is usually higher than that of a frying pan.

[0051] In another embodiment, the detection device may further include both the ranging device and the vision device. In this embodiment, the type of cooking utensil is first determined independently using both height data and image data. Only if the types determined by the two methods match can the type of cooking utensil be confirmed; if the types determined by the two methods differ, a new determination is required. This embodiment uses two determination methods to corroborate the determination of the cooking utensil type, effectively improving the accuracy of the determination.

[0052] In addition, the detection device may also include a smoke sensor and / or a vision device for acquiring smoke volume data. The smoke sensor can directly acquire smoke volume data, while the vision device can identify the amount of smoke through cooking images, so that the processor of the side-suction range hood can control the opening and closing state of the upper smoke inlet panel 104 based on the smoke volume data.

[0053] The above description is only a preferred embodiment of the present utility model and does not limit the scope of protection of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
