Description

A near-suction narrow-body range hood

technical field

The utility model relates to the technical field of range hoods, in particular to a near-suction narrow body range hood.

Background technique

The side-suction range hoods currently on the market are designed to absorb as much oil fume as possible during the cooking process and ensure strong suction. Generally, the smoke collection chamber is bulky, with many air inlets and large fan power. Production cost and energy consumption are relatively high. If the problems of increasing the power of the fan, increasing the volume of the smoke collecting cavity, and setting more air inlets are overcome by shortening the distance between the cooktop and the air inlet of the hood, it will inevitably lead to a reduction in the operating space of the cook and frequent collision incidents . According to the national standard, the height of the bottom of the European-style range hood from the stove should not be less than 600mm, and the height of the bottom of the side-suction range hood should not be less than 350mm from the stove, so as to ensure that the cook has enough operating space. In addition, the angle between the front panel and the vertical direction of the side suction range hood in the prior art is generally 30° to 45°, so the side panel must protrude more from the horizontal range of the upper casing, thereby increasing the The thickness of the fuselage is prone to bumps and reduces the operating space.

For example, the application publication number is CN106705159A, entitled an L-shaped range hood with an openable bottom air inlet, which discloses an L-shaped range hood with an openable bottom air inlet. The air inlet includes an upper air inlet and a lower air inlet. The lower air inlet is arranged on the inner concave surface of the L-shaped structure of the main frame and is located at the lower part of the main frame, the upper air inlet is arranged on the top surface of the inner concave surface, and the lower air inlet is matched with a Bezel that can be opened and closed. The technical solution provided by this application for the invention requires the installation of a larger-power fan in order to ensure the smoking effect of the upper and lower air inlets of the hood, and its production cost and energy consumption are high, and the impact of noise is large; the position of the air inlet of the hood If there are too many, it will inevitably lead to too wide hood, reduced operating space, prone to bumping incidents, and more air inlets will easily cause problems such as difficult cleaning and lack of integrity in the appearance of the hood.

Wherein, the ratio of the rotating diameter of the booster blade to the diameter of the turbine is 0.4 to 0.5.

Wherein, the panel is a glass panel.

In the above technical solution provided by the utility model, the side facing the cooker is a glass panel, which has a high-grade appearance and is easy to clean; the air inlet is set within a third of the height of the lower part of the panel, closer to the cooker, and the air inlet is farther away from the cooker. The height of the hood is 250mm to 340mm. The oil fume generated during the cooking process is sucked away by the hood before it diffuses. It is not necessary to increase the power of the fan or increase the volume of the hood to ensure that the hood has a strong smoking effect; this structure The setting also makes the hood thinner as a whole, the cooker has more room to operate, and avoids bumps; this structural design significantly increases the suction effect of the turbine, thereby improving the efficiency of the fan and reducing noise. At the same time, due to The length of the supercharging vane is small, so that only a little oil stain will be left on the vane, and the weight of the vane will not be increased, thereby enhancing the suction effect and reducing the noise.
