Description

Technical Field

[0001] This utility model relates to the field of range hoods, specifically a desktop range hood. Background Technology

[0002] Desktop range hoods, as small and portable appliances, effectively extract cooking fumes, keeping the kitchen air fresh. To better collect fumes, current desktop range hoods typically extend the fume-blocking component beyond the main body, making it convenient to position it above the cooking area for improved fume collection efficiency. However, this also leads to some inconveniences. First, because the fume-blocking component extends beyond the main body, it occupies considerable space when not in use, especially for families with limited kitchen space, increasing storage difficulty. Second, its location above the cooking area increases the component's contact with cooking fumes, requiring regular cleaning. To avoid water entering the main body during cleaning, users usually can only wipe it with a cloth, increasing the difficulty and time required for cleaning.

[0003] Therefore, there is a need to develop desktop range hoods that can reduce space occupation and are easy to clean. Utility Model Content

[0004] To address the aforementioned problems of large space occupation and inconvenient cleaning in existing desktop range hoods, the technical solution adopted by this utility model is as follows:

[0005] A desktop range hood includes a main body, wherein the main body includes a drive assembly and a fume-blocking assembly for collecting fumes. The drive assembly has an air duct for exhaust, and the fume-blocking assembly has a smoke inlet. The main body has an unfolded state and a retracted state. When the main body is in the unfolded state, the air duct and the smoke inlet are connected. The fume-blocking assembly is detachably connected to the main body, so that the main body can be switched between the unfolded state and the retracted state.

[0013] Furthermore, in the desktop range hood described in the solution, the drive component is further provided with a second mating end set at an angle to the horizontal plane, and the smoke-blocking component is further provided with a first mating end that mates with the second mating end. The first pair of interfaces is located at the first mating end, and the second pair of interfaces is located at the second mating end. When the main body of the range hood is in the unfolded state, the smoke-blocking component and the drive component are set at an angle α, and the range of α is 90°-150°.

[0014] Furthermore, in the desktop range hood described in the solution, the second pair of interfaces and the exhaust vent are both located on the upper side of the drive assembly, and the cross-section of the air duct is U-shaped to connect the second pair of interfaces and the exhaust vent.

[0015] Furthermore, in the desktop range hood described in the solution, the first mating end is further provided with a locking groove, and the second mating end is further provided with a locking part that engages with the locking groove.

[0016] The beneficial effects of this utility model are as follows:

[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] Example 1: As Figure 1-9 The desktop range hood shown includes a range hood body 1, wherein the range hood body 1 includes a drive assembly 2 and a fume-blocking assembly 3 for collecting fumes. The drive assembly 2 is provided with an air duct 21 for exhaust, and the fume-blocking assembly 3 is provided with a smoke inlet 31. The range hood body 1 has an unfolded state and a retracted state. When the range hood body 1 is in the unfolded state, the air duct 21 and the smoke inlet 31 are connected. The fume-blocking assembly 3 is detachably connected to the range hood body 1 so that the range hood body 1 can be switched to the unfolded state or the retracted state.

[0031] The middle fume baffle assembly 3 and the drive assembly 2 of this utility model are connected by a detachable structure, which allows the user to remove the fume baffle assembly 3 for separate cleaning, thereby reducing the difficulty of cleaning.

[0032] This utility model sets the main body 1 of the range hood to have an unfolded state and a retracted state, so that when not in use, the oil fume blocking component 3 can be disassembled and separated from the drive component 2 or folded into a retracted state, thereby greatly reducing the space occupied by the equipment.

[0033] Furthermore, compared to traditional desktop range hoods where only the surface of the fume-blocking component can be wiped during cleaning, this invention, through a detachable connection structure between the fume-blocking component 3 and the drive component 2, allows users to completely disassemble the fume-blocking component 3 for rinsing. This not only reduces cleaning difficulty and more effectively removes grease and dirt, improving hygiene standards, but also enhances the user experience. Furthermore, this design also frees the cleaning of the fume-blocking component 3 from the overall structure of the range hood body 1, making the cleaning process more flexible and efficient. Furthermore, by designing the range hood body 1 with both an unfolded and retracted state, when not in use, users can detach the fume-blocking component 3 from the drive component 2 and form a compact retracted state with it. This design effectively reduces the space occupied by the device compared to traditional fixed fume-blocking components 3. Furthermore, in this embodiment, the fume-blocking component 3 and the range hood body 1 are connected by a snap-fit ​​mechanism.

[0034] Example 2: Further, such as Figure 1-9 The desktop range hood shown includes a fume-blocking component 3 with a first pair of interfaces 32 and a connecting cavity 33 connecting the first pair of interfaces 32 and the smoke inlet 31. The drive component 2 also includes a second pair of interfaces 22 connecting the ventilation duct 21. When the main body 1 of the range hood is in the unfolded state, the first pair of interfaces 32 and the second pair of interfaces 22 are connected.

[0035] This embodiment includes the features of Embodiment 1, the difference being that, by providing a first pair of interfaces 32 and a connecting cavity 33 connecting the first pair of interfaces 32 and the smoke inlet 31 in the fume-blocking assembly 3, and providing a second pair of interfaces 22 connecting the ventilation duct 21 in the driving assembly 2, when the desktop range hood is in the unfolded state, the first pair of interfaces 32 of the fume-blocking assembly 3 and the second pair of interfaces 22 of the driving assembly 2 are connected. This arrangement ensures a tighter connection between the fume-blocking assembly 3 and the driving assembly 2 during use, preventing oil fumes from leaking from the connection between the first pair of interfaces 32 and the second pair of interfaces 22, and effectively improving the oil fume extraction efficiency. Furthermore, by providing the connecting cavity 33, the oil fumes entering from the smoke inlet 31 can be smoothly guided into the ventilation duct 21, reducing airflow resistance, improving the oil fume extraction efficiency, and helping to reduce noise levels. Furthermore, in some embodiments, to further improve the sealing of the connection between the first pair of interfaces 32 and the second pair of interfaces 22, a sealing element can also be provided at the connection between the first pair of interfaces 32 and the second pair of interfaces 22.

[0036] Example 3: Further, such as Figure 1-9 The desktop range hood shown has a drive assembly 2 with a storage area 23. When the main body of the range hood 1 is in the storage state, the smoke-blocking assembly 3 is fixed in the storage area 23.

[0037] This embodiment includes the features of Embodiment 2, the difference being that, by setting up a storage area 23, the oil fume blocking component 3 can be fixed within the storage area 23 of the drive component 2 when the main body 1 of the range hood is in the storage state. This setting not only effectively reduces the space occupied by the equipment, but also reduces the risk of losing parts compared to disassembling and storing them separately. Furthermore, fixing the oil fume blocking component 3 to the storage area 23 also simplifies the user's operation process, making the entire storage process faster and more convenient, and improving the user experience.

[0038] Example 4: Further, such as Figure 1-9 The desktop range hood shown is rectangular in shape when the main body 1 is in the storage state.

[0039] This embodiment includes the features of Embodiment 3, the difference being that, when the desktop range hood body 1 of this utility model is in the storage state, it is generally rectangular. This design can improve the space utilization of the desktop range hood, allowing it to be placed in a small space, thereby saving space. Furthermore, this design can also enhance the stability and structural strength of the range hood body 1 in the storage state, reducing the risk of damage caused by accidental collisions. Furthermore, this design can also make the desktop range hood more efficient in transportation and packaging, reducing logistics costs. Furthermore, this design also helps to improve the aesthetics of the desktop range hood. Furthermore, in some embodiments, in order to further reduce the volume of the range hood body 1 in the storage state, the desktop range hood body 1 is generally cubic in the storage state.

[0040] Example 5: Further, such as Figure 1-9 The desktop range hood shown has a storage area 23 with a supporting step 231 for supporting the smoke-blocking component 3. The cross-section of the storage area 23 is L-shaped, and the shape of the smoke-blocking component 3 is adapted to the shape of the storage area 23.

[0041] This embodiment includes the features of Embodiment 4, the difference being that, by setting the storage area 23 in an L-shape, a supporting step 231 for supporting the fume-blocking component 3 is formed in the storage area 23. This setting ensures that the fume-blocking component 3 can be placed more stably in the storage area 23, avoiding the risk of accidental movement due to external environmental factors. Furthermore, the setting of the supporting step 231 provides a reference surface for the fume-blocking component 3 in its stored state, so that the fume-blocking component 3 can complete the switch to the stored state simply by placing it on the supporting step 231, thereby facilitating the user's installation and disassembly operations and improving the user experience. Furthermore, by setting the shape of the fume-blocking component 3 to match the shape of the storage area 23, the space utilization efficiency can be effectively optimized, minimizing the space occupied by the range hood body 1 in the stored state.

[0042] Example 6: Further, such as Figure 1-9 The desktop range hood shown includes a drive assembly 2 with an exhaust vent 24 connected to the air duct 21. The drive assembly 2 also includes an odor removal assembly 4 fixed to the exhaust vent 24, which is detachably connected to the exhaust vent 24.

[0043] This embodiment includes the features of Embodiment 5, the difference being that, since the grease-blocking component 3 isolates the odorous gas, this invention provides an odor-removing component 4 at the exhaust vent 24. The odor-removing component 4 removes the odor before the gas is exhausted, providing users with a fresher and more comfortable kitchen environment. Furthermore, the odor-removing component 4 is detachably installed on the exhaust vent 24, which not only facilitates cleaning or replacement of the odor-removing component 4 according to actual needs to maintain its efficient odor removal effect, but also reduces maintenance costs and increases the flexibility of use. Furthermore, in this embodiment, the odor-removing component 4 contains activated carbon; in other embodiments, the odor-removing component 4 may also contain other materials that efficiently absorb odors. Furthermore, in this embodiment, the odor-removing component 4 is connected to the exhaust vent 24 via a snap-fit ​​connection.

[0044] Example 7: Further, such as Figure 1-9 The desktop range hood shown includes an oil-blocking mesh 34 fixed to the smoke inlet 31, wherein the oil-blocking assembly 3 further includes an oil-blocking mesh 34 detachably connected to the smoke inlet 31.

[0045] This embodiment includes the features of Embodiment Six, the difference being that, by providing an oil-blocking mesh 34 fixed to the smoke inlet 31 on the oil fume blocking assembly 3, this utility model effectively prevents most oil stains from entering the connecting cavity 33 through the smoke inlet 31, thereby reducing the need for internal cleaning; furthermore, the oil-blocking mesh 34 is installed on the smoke inlet 31 in a detachable connection manner, which facilitates users to clean the oil-blocking mesh 34 regularly and prevents oil stains from accumulating and affecting equipment performance and hygiene conditions; furthermore, this setting allows users to easily remove the oil-blocking mesh 34 to clean the connecting cavity 33, effectively reducing the difficulty of cleaning the connecting cavity 33; furthermore, in this embodiment, the oil-blocking mesh 34 and the smoke inlet 31 are connected by a snap-fit ​​connection.

[0046] Example 8: Further, such as Figure 1-9 The desktop range hood shown includes an oil fume blocking component 3 that is also provided with an oil collection chamber 35 that communicates with the connecting cavity 33. The oil fume blocking component 3 also includes a cover plate 36 for covering the oil collection chamber 35, and the cover plate 36 is detachably connected to the oil collection chamber 35.

[0047] This embodiment includes the features of Embodiment Seven, the difference being that, by providing an oil collecting chamber 35 connected to the connecting cavity 33, the oil produced during cooking is guided to the oil collecting chamber 35 instead of remaining in the connecting cavity 33. This not only effectively avoids the problem of oil accumulation in the connecting cavity 33, but also ensures unobstructed airflow, thereby maintaining efficient oil fume extraction performance. Furthermore, the oil fume blocking assembly 3 also includes a cover plate 36 for covering the oil collecting chamber 35. The cover plate 36 is detachably connected to the oil collecting chamber 35. This design not only makes it convenient for users to periodically remove the cover plate 36 to clean the oil collecting chamber 35, but also simplifies the cleaning process. Furthermore, the cover plate 36 and the oil collecting chamber 35 are connected by a snap-fit ​​mechanism, allowing users to easily remove the cover plate 36 to clean the oil collecting chamber 35 without complicated tools or steps, effectively reducing the difficulty of cleaning. Furthermore, in this embodiment, the cover plate 36 and the oil collecting chamber 35 are connected by a snap-fit ​​mechanism.

[0048] Example 9: Further, such as Figure 1-9 The desktop range hood shown has a drive assembly 2 with a second mating end 25 set at an angle to the horizontal plane, and a smoke-blocking assembly 3 with a first mating end 37 that mates with the second mating end 25. The first pair of interfaces 32 are located at the first mating end 37, and the second pair of interfaces 22 are located at the second mating end 25. When the range hood body 1 is in the unfolded state, the smoke-blocking assembly 3 and the drive assembly 2 are set at an angle α, where α ranges from 90° to 150°.

[0049] This embodiment includes the features of Embodiment 8, the difference being that the drive component 2 in this utility model has a second mating end 25 set at an angle to the horizontal plane, while the fume-blocking component 3 has a first mating end 37 that mates with the second mating end 25. Through the mating of the first mating end 37 and the second mating end 25, when the range hood body 1 is in the unfolded state, the fume-blocking component 3 can extend out of the drive component 2 and be set at an angle to the drive component 2. This setting allows the fume-blocking component 3 to be positioned above the cooking area to improve the efficiency of fume extraction. Furthermore, the angle between the fume-blocking component 3 and the drive component 2 is between 90° and 150°. This setting ensures that the fume-blocking component 3 is not too close to the cooking appliance, avoiding the impact of excessively close distance on the fume extraction effect, the risk of overheating of the equipment, and obstruction of the user's view. At the same time, it is not so large that it cannot effectively remove fumes. The system covers the area where oil fumes are emitted, thus ensuring optimal oil fume extraction performance. Furthermore, if the angle α is less than 90°, the oil fume blocking component 3 will be too close to the cooking appliance, preventing it from effectively covering the entire oil fume emission area, affecting the oil fume extraction effect, and potentially increasing the risk of overheating due to the close proximity. Additionally, it may obstruct the user's view, affecting the cooking process. If the angle is greater than 150°, the oil fume blocking component 3 will not effectively cover the oil fume emission area, causing some oil fumes to escape into the kitchen environment, reducing oil fume extraction efficiency. Furthermore, it will make the overall structure of the device unstable, increasing the risk of tipping over. In this embodiment, the angle α between the oil fume blocking component 3 and the drive component 2 is 120°. The first mating end 37 and the second mating end 25 can be connected by means of snaps, magnets, threaded fasteners, mortise and tenon joints, grooves, etc.

[0050] Example 10: Further, such as Figure 1-9 The desktop range hood shown has the second pair of interfaces 22 and the exhaust vent 24 both located on the upper side of the drive assembly 2, and the air duct 21 has a U-shaped cross-section to connect the second pair of interfaces 22 and the exhaust vent 24.

[0051] This embodiment includes the features of Embodiment Nine, the difference being that by placing the second pair of interfaces 22 and the exhaust port 24 on the upper side of the drive assembly 2, and by setting the cross-section of the air duct 21 in a U-shape, the fumes drawn in from the smoke inlet 31 can smoothly pass through the connecting cavity 33, the first pair of interfaces 32, and the second pair of interfaces 22 into the air duct 21, and finally be discharged from the exhaust port 24. The U-shaped air duct effectively reduces the resistance of airflow during transmission, improves the efficiency of fume extraction, and also helps to reduce noise levels. Furthermore, in this embodiment, the fan is located on the side of the air duct 21 closer to the exhaust port 24, and the U-shaped air duct 21 ensures that even if a small amount of grease enters the air duct 21, it will adhere to the inner wall of the air duct 21 before contacting the fan, thus avoiding contact between the grease and the fan. Furthermore, the U-shaped air duct 21 can also maximize the usable space inside the drive assembly 2, making the entire device more compact.

[0052] Example 11: Further, such as Figure 1-9 The desktop range hood shown has a first mating end 37 with a locking groove 371 and a second mating end 25 with a locking part 251 that engages with the locking groove 371.

[0053] This embodiment includes the features of Embodiment 10, the difference being that the present invention provides a locking groove 371 at the first mating end 37 and a locking part 251 at the second mating end 25 that engages with the locking groove 371, so that the fume-blocking component 3 and the driving component 2 are connected by locking. This setting ensures that the two can be quickly and accurately aligned and firmly connected during installation, reducing assembly time and complexity, while enhancing the overall stability of the equipment. Furthermore, in this embodiment, the locking part 251 is set upward, so that the user can lower the fume-blocking component 3 from above the driving component 2, thereby engaging the locking groove 371 with the locking part 251. This setting effectively simplifies the steps for the user to install the fume-blocking component 3 and the driving component 2.

[0054] Example 12:

[0055] This embodiment includes the features of embodiments one through eleven, the difference being that in this embodiment, the angle α between the fume-blocking component 3 and the driving component 2 is 90°.

[0056] Example 13:

[0057] This embodiment includes the features of embodiments one through ten, the difference being that in this embodiment, the angle α between the fume-blocking component 3 and the driving component 2 is 150°.

[0058] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments.
