Embodiment Construction

[0028] As shown in Fig. 1, the range hood includes a chassis 1 and a blower fan 2, etc., wherein the passage between the air inlet 101 of the chassis 1 and the suction port 201 of the fan is the suction passage, and the fan blade in the fan 2 is connected to the air outlet pipe. The passage between them is an exhaust passage, and two rows of cooling grilles 41 and 42 are fixed in sequence on the inner side of the air inlet 101 of the chassis; from Fig. 4 and Figure 5 It can be seen in the figure that the cooling grid is stamped with a thin plate. First, the thin plate is punched into a comb shape. The gap between the comb teeth is the tuyere 410, and then the water tank 411 and the eight cooling fins are stamped on the eight comb teeth. 41 forms a row of cooling grids on the same plane, and finally bends the lower part of the connecting comb teeth into a water collection tank 401 (see figure 2 The enlarged picture of the bottom of the sump 401), and the outer bottom of the su...

Abstract

The invention relates to an environment-friendly range hood with simple structure, low cost and capable of effectively separating oil fume, which includes a chassis, a suction channel, an exhaust channel, a fan and a switch, and is characterized in that the fan is located between the suction channel and the exhaust channel Between them, the suction channel and the exhaust channel form a flue; the flue is provided with a number of cooling fins inclined downward along the air inlet direction, and the surface of the cooling fins facing away from the air inlet direction is a water tank set from top to bottom , the lower end of the water tank is connected with the water collection tank, and each cooling fin forms a row of cooling grids on the same plane along the radial direction of the flue, and there is a tuyere between adjacent cooling fins, and a leaking pipe is fixed on the upper part of the cooling fin, and the leaking pipe There are water leakage holes corresponding to the water tanks of each cooling fin; the water tank, water pump, leaking pipe, cooling fin water tank and water collection tank fixed in the chassis form a water circulation loop.

Description

technical field [0001] The invention relates to a range hood, in particular to a range hood with an oil separation function. Background technique [0002] A general range hood includes a smoke collecting hood, a suction channel, an exhaust channel, a switch and a fan, wherein the fan is installed between the suction channel and the exhaust channel, and when the fan starts, the oil fume mixture is inhaled through the suction channel and then passed through the suction channel. The exhaust air channel is exhausted to the outside. The existing range hood directly discharges the mixed gas of oil fume to the outside, which causes great pollution to the environment. In the Chinese patent ZL0026044.2 with the announcement number CN2435669Y published on June 20, 2001, a "new range hood" is disclosed, which includes a housing, a suction and discharge device, a purification treatment chamber and a low-pressure exhaust valve, and the suction and discharge device It includes a diversi...
