Description

Technical Field

[0001] The utility model relates to an oil fume machine, in particular to an oil fume machine with a detachable and installable smoke collecting plate. Background Art

[0002] An oil fume machine is a common electrical appliance in the kitchen, mainly used to suck oil fume and waste gas generated during cooking to improve the kitchen environment. At present, the oil fume machines on the market are roughly divided into several types such as top suction type, side suction type and built-in type. No matter which type, how to effectively suck oil fume and prevent oil fume diffusion are key problems in the design.

[0003] In the prior art, most oil fume machines are equipped with a smoke collecting plate, also known as a smoke gathering plate or a smoke guiding plate. Its main function is to guide oil fume to the smoke suction port through a physical barrier effect, improving the capture efficiency of oil fume. This kind of smoke collecting plate is usually fixedly installed on both sides or the bottom of the oil fume machine. Although the fixed installation design can ensure a stable structure and continuous smoke guiding effect to a certain extent, it also has the following obvious limitations:

[0004] 1. The smoke collecting plates of most oil fume machines on the market at present are fixed on the main body of the oil fume machine, and users cannot flexibly adjust or disassemble them during daily use. Although this fixed installation design can provide a stable structure and continuous smoke guiding effect, for different usage scenarios and requirements, users cannot freely choose whether to install the smoke collecting plate. For example, in some cases, users may hope to increase the aesthetic appearance of the oil fume machine, or need more operating space during cooking. At this time, the fixed smoke collecting plate may be inconvenient.

[0005] 2. In the design of the oil fume machine, the air guiding plate is an important component for optimizing the air flow and improving the oil fume absorption efficiency. However, over time, a large amount of oil stains will accumulate on the air guiding plate, and it needs to be cleaned regularly to maintain its normal function. However, in the existing oil fume machines, the air guiding plate is usually fixed on the main body through a complex installation structure. Once it needs to be disassembled and cleaned, the entire oil fume machine or its main part often needs to be disassembled, which brings great inconvenience to the daily maintenance of users. The complex disassembly and assembly process not only increases the difficulty of cleaning, but also easily causes damage to the oil fume machine or shortens its service life.

[0006] In summary, the oil fume machines in the prior art have obvious deficiencies in the fixed installation of the smoke collecting plate and the cleaning of the air guiding plate, and cannot meet the increasingly diverse usage needs of users. Therefore, it is necessary to make further improvements to it. Content of the Utility Model

[0028] The following further specifically describes the present utility model with reference to the accompanying drawings. An oil fume suction machine with a detachable smoke collecting plate includes a main body 1. A smoke suction port 2 is provided at the front of the main body 1. The smoke suction port 2 is communicated with a smoke extraction fan 3 inside the main body 1. When the smoke extraction fan 3 operates, a negative pressure is generated at the smoke suction port 2 to suck oil fume. An upper air guide plate 4 and a lower air guide plate 5 are covered on the smoke suction port 2;

[0029] Among them, hinge holes 41 are provided on both sides of the top of the upper air guide plate 4. A hinge seat 21 is provided at the top of the smoke suction port 2. A hinge shaft 22 is inserted into the hinge hole 41 after passing through the outer end of the hinge seat 21, and the upper air guide plate 4 is hingedly installed on the smoke suction port 2. An upper power device is further provided inside the main body 1 to push the upper air guide plate 4 to turn outwards to open the smoke suction port 2;

[0030] Among them, a hinge 51 is installed at the bottom of the lower air guide plate 5, and the other end of the hinge 51 is connected to the main body 1. A lower power device is further provided inside the main body 1 to push the lower air guide plate 5 to turn inwards to open the smoke suction port 2;

[0031] The two sides of the main body 1 are detachably installed with smoke collecting plates 7 through hanging plates 6. The left and right smoke collecting plates 7 and the main body 1 enclose a smoke collecting area 71. The smoke suction port 2 is provided at the bottom of the smoke collecting area 71.

[0032] In one embodiment: the smoke collecting plate 7 is made of tempered glass, and the hanging plate 6 is fixedly adhered to the inner side surface of the smoke collecting plate 7. A hanging groove 11 is provided on the side wall of the main body 1. A hook 61 is provided on the hanging plate 6 and extends into the hanging groove 11 for fixation, and the smoke collecting plate 7 is installed on both side walls of the main body 1.

[0033] In one embodiment: an end plate 12 is provided at the top of the main body 1, and a front panel 13 is covered and installed on the surface of the end plate 12. The front panel 13 is detachably installed on the end plate 12 through a hanging plate 6.

[0034] In one embodiment: the left and right sides of the end plate 12 extend outwards, and the smoke collecting plate 7 is covered and arranged on its back surface.

[0035] In one embodiment: the upper power device is an upper reduction motor provided inside the main body 1. An upper swing arm is installed on the output shaft of the upper reduction motor. The upper swing arm is hinged to an upper linkage seat 81 provided on the back of the upper air guide plate 4 through an upper connecting rod 8.

[0036] In one of the embodiments: The lower power device is a lower reduction motor 9 disposed within the main body 1. A lower swing arm 91 is mounted on the output shaft of the lower reduction motor 9. The lower swing arm 91 is hinged to a lower linkage seat 93 provided on the back of the lower air deflector 5 through a lower connecting rod 92.

[0037] Working principle: When the range hood is started, the smoking fan 3 within the main body starts to operate. At the same time, the upper air deflector opens outwards and the lower air deflector opens inwards, thereby increasing the opening area of the smoking port, forming a negative pressure area at the smoking port 2, generating suction force, and quickly sucking the oil fumes generated during the cooking process into the smoking port 2. To enhance the oil fume capture effect, the range hood is designed with a detachable smoke collecting plate 7. The smoke collecting plate 7 is fixed to both sides of the main body 1 through hanging plates 6 and hooks 61, such that a closed or semi-closed smoke collecting area 71 is formed on the left and right sides and in front of the range hood. The oil fumes are effectively controlled within the smoke collecting area 71, reducing the chance of the oil fumes spreading to the surrounding environment.

[0038] Among them, the upper air deflector 4 and the lower air deflector 5 not only help to divert the oil fumes into the smoking port 2, but also prevent external air from directly entering the smoking port 2 to a certain extent, thereby improving the smoking efficiency.

[0039] Among them, for the convenience of cleaning and maintenance, the range hood of the present utility model is designed with a detachable structure for each component: The smoke collecting plate 7 is connected to the hanging grooves 11 on both sides of the main body 1 through hooks 61, and the user can easily disassemble the smoke collecting plate 7 for separate cleaning.

[0040] In addition, the front panel 13 is fixed to the end plate 12 of the main body 1 and is detachably installed through the hanging plate 6, enabling the user to conveniently disassemble the front panel 13 for cleaning or replacement.

[0041] Furthermore: The hinged design of the upper air deflector 4 and the lower air deflector 5 enables them to be simply flipped open or disassembled, and the user can easily access these air deflectors for cleaning, ensuring that the surface of the air deflectors will not affect the smoking effect due to the accumulation of oil stains. It should be emphasized that: The smoke collecting plate in this case in China can be disassembled. Therefore, hinge holes 41 are provided on both sides of the top of the upper air deflector 4, and hinge seats 21 are provided at the top of the smoking port 2. The hinge shaft 22 is inserted into the hinge holes 41 after passing through the outer ends of the hinge seats 21, hinging and installing the upper air deflector 4 on the smoking port 2. In this structure, since the hinge shaft can be inserted from both sides of the range hood after disassembling the smoke collecting plate, when observing the upper air deflector from its front, the hinge hole structure will not be seen, while maintaining its neat and beautiful appearance, avoiding the disadvantages of the hinge structure in traditional air deflectors being exposed and prone to accumulating oil stains.

[0042] Due to the detachable design of the above components, users can freely adjust and maintain the range hood according to actual usage conditions and requirements. For example, users can assemble the smoke collecting plate 7 during daily cooking to improve the oil fume collection efficiency, and when cleaning or maintaining, they can easily disassemble the smoke collecting plate, the front panel, and the air deflector. In this way, the range hood not only adapts to a variety of different usage scenarios but also significantly reduces the cleaning and maintenance difficulty for users.

[0043] In summary, the detachable smoke collecting plate range hood of the present utility model realizes efficient oil fume collection and diversion through optimized design and reasonable working principles, and provides great convenience and flexibility in terms of cleaning and maintenance. Users can enjoy a powerful, easy-to-operate and maintain range hood, which significantly improves the kitchen usage environment, so it can be widely promoted and used.

[0044] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom still fall within the protection scope of the claims of the present utility model.
