Description

Technical Field

[0001] This utility model relates to the technical field of range hood equipment, specifically to a double-layer air intake range hood. Background Technology

[0002] A range hood is a kitchen appliance specifically designed to purify the kitchen environment. It can quickly expel cooking fumes, odors, and moisture generated during cooking, thereby keeping the kitchen air clean.

[0003] Cooking fumes typically enter the range hood through its air inlet. However, the fumes tend to disperse before entering the inlet, which reduces the efficiency of their entry. Furthermore, users' hands can easily come into contact with moving parts inside the range hood through the air inlet, posing a potential safety hazard.

[0004] Therefore, further improvements are needed. Utility Model Content

[0025] Figure 6 This is an enlarged view of embodiment A of the present invention. Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] See Figures 1-6 This dual-layer air intake range hood includes a range hood body 1, which has an air intake section. The air intake section includes an air inlet 11 and a collecting slope 12. The air inlet 11 is located in the middle of the air intake section. The collecting slope 12 is inclined towards the outside of the range hood body 1 along the periphery of the air inlet 11. The air inlet 11 is connected to a baffle 2, which has a vent structure 21. The collecting slope 12 can concentrate the fumes before they enter the air inlet 11, which helps to improve the efficiency of the fumes entering the air inlet 11. At the same time, the baffle 2 can prevent the user's hands from touching the moving parts inside the range hood through the air inlet 11, thus improving the safety of the product.

[0028] Furthermore, an installation recess 111 is provided around the air inlet 11, the inner side of the baffle 2 abuts against the installation recess 111, and the periphery of the baffle 2 abuts against the installation recess 111, thereby improving the installation accuracy of the baffle 2 and the air inlet 11 and the stability of the connection structure.

[0029] Furthermore, the depth of the recessed step 111 is comparable to the thickness of the baffle 2, making the product more aesthetically pleasing.

[0030] Furthermore, a positioning mechanism is provided between the mounting recess 111 and the baffle 2. The baffle 2 is detachably connected to the mounting recess 111 through the positioning mechanism, which facilitates the disassembly and cleaning of the baffle 2.

[0031] Furthermore, the positioning mechanism includes a positioning block 23 and a positioning hole 1111. The positioning block 23 is located on the periphery of the inner side of the baffle 2, and the positioning hole 1111 is located on the bottom periphery of the mounting recess 111. The positioning block 23 and the positioning hole 1111 are inserted and engaged to enable the baffle 2 and the mounting recess 111 to be installed and positioned, thereby achieving a rapid positioning effect between the baffle 2 and the mounting recess 111 and improving assembly efficiency and accuracy.

[0032] Furthermore, the positioning mechanism also includes an internal threaded hole 1112 and an external threaded hole 22. The internal threaded hole 1112 and the external threaded hole 22 are respectively provided on the mounting recess 111 and the baffle 2. The internal threaded hole 1112 and the external threaded hole 22 are locked together by a screw device to fix the baffle 2 to the mounting recess 111, thereby further improving the connection strength between the baffle 2 and the mounting recess 111 and preventing the baffle 2 from accidentally falling off during use.

[0033] Furthermore, several guide grooves 121 are distributed on the air collecting slope 12. The guide grooves 121 are in the shape of a spiral arm. The guide grooves 121 can guide the airflow to form a rotating trend as it flows through the air collecting slope 12. Taking this embodiment as an example, the guide grooves 121 are in the shape of a spiral arm in the clockwise direction. When the airflow passes through, the whole can form a clockwise rotating airflow, which further improves the efficiency of the airflow entering the air inlet 11. Moreover, the rotating airflow can further attract the surrounding oil fumes.

[0034] Furthermore, the range hood body 1 is connected to a front air guide plate 3. Support parts 31 are provided on the left and right sides of the front air guide plate 3. The support parts 31 extend in the rearward direction and are connected and cooperate with the range hood body 1. The outer edge of the front air guide plate 3 protrudes in the frontward direction relative to the support parts 31. An air intake chamber 32 is formed on the rear side of the front air guide plate 3. The upper and / or lower sides of the air intake chamber 32 are open.

[0035] In this embodiment, the upper and lower sides of the air intake chamber 32 are both open. When the range hood is working, the fumes first enter the air intake chamber 32 through the openings on the upper and lower sides respectively. The front guide plate 3 can divert the fumes and then concentrate them into the air intake chamber 32, so that the fumes can first enter the air intake chamber 32 in a more concentrated manner and then be sucked by the range hood, thereby improving the fume extraction effect.

[0036] Furthermore, a lower side plate 33 is provided on the lower side of the front guide plate 3, and an abutment part 34 for connecting and cooperating with the range hood is provided on the side of the lower side plate 33 away from the range hood body 1, which can further improve the stability of the connection and cooperation between the front guide plate 3 and the range hood.

[0037] Furthermore, the abutment part 34 is flat and extends across the lower edge of the lower side plate 33. The abutment part 34 extends downward and can also guide oil stains to drip downward. Specifically, an oil collection groove can be provided below the abutment part 34 of the range hood to facilitate users to collect and clean oil stains.

[0038] Furthermore, the lower side plate 33 has several grille holes 331 distributed on it, which can improve the efficiency of oil fumes entering the air intake chamber 32 through the lower side plate 33.

[0039] The lower side panel 33 is provided with symmetrically arranged grille groups, each of which includes several grille holes 331. The grille holes 331 are inclined from bottom to top in a direction away from the center of the lower side panel 33, so that the oil fumes tend to diffuse outward after entering the air intake chamber 32, and the oil fumes can be drawn by different positions of the range hood air inlet 11, further improving the oil fume extraction efficiency.

[0040] The above embodiments are merely preferred embodiments of this utility model, and other implementations are also possible. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model, and all such equivalent modifications or substitutions are included within the scope set forth in the claims of this application.
