Description

Technical Field

[0001] The utility model relates to a range hood, in particular to a range hood with omnidirectional air intake. Background Art

[0002] As a common household appliance, the range hood has been widely used in the kitchen. The range hood can quickly extract the waste from the stove combustion and the oil smoke generated during the cooking process that is harmful to the human body and discharge it outdoors. At the same time, it condenses and collects the oil smoke, reduces pollution, purifies the air, and has anti-toxic and explosion-proof safety protection functions. Therefore, the range hood allows people to cook in a kitchen without oil smoke, providing people with a good cooking environment. The main unit of the range hood generally includes a casing, a bellows and a fan. The fan is set in the bellows. When the fan is started, a negative pressure is formed in the bellows, so that the oil smoke and other harmful gases in the kitchen enter the bellows through the air inlet of the range hood, and are discharged to the outside through the exhaust pipe, thereby ensuring a smoke-free environment in the kitchen.

[0003] In order to ensure the oil absorption effect of the range hood, a large air outlet is often designed for air absorption. The design of the large air outlet exposes the internal components of the range hood to the user's sight, reducing its external aesthetics. At the same time, it also causes its components to work in a long-term exposed environment, which is prone to accumulation of oil stains and dust, and the range hood is prone to wear and tear, reducing its service life and increasing its use burden. At the same time, the design of a single large air outlet has a limited absorption range, and the absorption efficiency is low for the scattered and drifting oil smoke in the kitchen environment, and the oil absorption effect is not ideal.

[0029] The upper panel 41 and the lower panel 42 are made of glass.

[0030] Working principle: Compared with traditional range hoods, the air guide plate and the filter are installed at intervals in front and back, and an air inlet area is hollowed out between the two to conduct external air and the air intake. It should be noted that the air inlet area is set around the outer contour of the air guide plate, that is, the air inlet area can take in air from the outer contour of the air guide plate. When the range hood starts working, external oil smoke can be synchronously inhaled from multiple directions of the air inlet area, which is different from the traditional single air inlet setting, forming an all-round air intake effect, significantly improving the absorption efficiency of oil smoke, so that even scattered oil smoke or oil smoke at a lower position can be effectively absorbed, keeping the kitchen environment clean and hygienic. The all-round air intake effectively optimizes the air flow path, helps to inhale external oil smoke more evenly, and further enhances the oil absorption effect of the range hood.

[0031] In the air inlet area, the air guide plate is detachably installed by means of a mounting seat embedded in the air inlet area. The upper panel of the air guide plate covers the upper air inlet of the air inlet, and buckle seats are connected to the two sides of the back thereof, and buckle grooves are arranged through the end faces of the buckle seats; an insertion rod is installed at the top position corresponding to the air inlet, and when installing the upper panel, the insertion rod is used to pass through the open position of the buckle groove and be clamped above the buckle groove. When the upper panel needs to be disassembled, the insertion rod is also used to detach from the open position of the buckle groove, and the upper panel can be easily disassembled from the shell.

[0032] The lower panel of the air guide plate covers the lower air inlet of the air inlet, and lock buckles are connected to the two sides of the back of the air guide plate. A locking groove is provided at the corresponding position of the end surface of the mounting seat, and the lock buckle is inserted into the locking groove by sliding, so as to position and connect the lower panel with the mounting seat. In order to lock the connection between the lower panel and the mounting seat, a locking plate is also connected to the back of the lower panel, and the locking plate passes through the mounting seat and is screwed to the shell, so as to lock the lower panel.

[0033] The detachable connection design of the air guide plate allows users to easily remove the air guide plate for cleaning or replacement, maintaining air intake efficiency and extending the life of the equipment. With this design, maintenance and cleaning of the range hood becomes more convenient, ensuring long-term stable and efficient working performance.

[0034] Furthermore, on both sides of the above-mentioned mounting base, side panels are bent and extended from the main body, and a number of side air inlets are opened through the side panels. The side air inlets are connected to the air intake port through the air inlet area. The side air inlets provide an entrance for the flow of air and also hide the internal components of the range hood to a certain extent, avoiding exposure to the user's line of sight and improving the overall appearance.

[0035] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
