Definitions

  • the invention relates to a soot removing device, in particular to a gas flow directed driving fume removing device.
  • the household smoke removal device generally has only one suction port. Because the negative pressure of the suction port is limited and the distance between the suction port and the oil smoke source is large, the soot is quickly diffused under the action of molecular thermal motion to cause overflow, so that the oil smoke is not complete.
  • a pressure fluid outlet port parallel to the diffusion surface is disposed on one side of the surface, and the air outlet is connected to the pressure fluid source, and a negative pressure fluid suction port parallel to the diffusion surface is disposed on the other side symmetrical with the position, the suction port Connecting a negative pressure generating device: the fluid blown from the air outlet enters the suction port to form a fluid diaphragm, which surrounds the pollution source soot diffusion space in the smoke passage from the air outlet to the suction port; In the soot channel from the outlet to the suction port, there is no moment to be drained, soot molecules will diffuse, and the longer the floating time, the more the soot molecules penetrate the hot diaphragm, the more overflow and diffusion will occur.
  • the exhaust device of the soot removing device of such a structure is disposed on the same side as the human operation, which is very inconvenient to operate and has a complicated structure.
  • the invention aims at the deficiencies in the prior art, and provides an airflow direction-driven driving fume removing device, which can enable the pollution source soot to be sucked away under the action of positive pressure instantaneously, and the soot is sucked away before being diffused to prevent soot. Diffusion, overflow, and the device is simple in structure and convenient in operation.
  • An airflow direction-driven soot removing device comprises an air suction port disposed on one side of a soot pollution source, and the air suction port is connected to the air suction device through a pipeline, and an air outlet device is disposed above the oil smoke pollution source.
  • the distance between the air outlet device and the soot pollution source is about 0.5 to 1 meter.
  • the projection of the air outlet device at the soot pollution source is located at the edge of the soot pollution source, and the projection position is opposite to the air suction port.
  • a bracket is arranged above the pipeline, and the air outlet device is mounted on the bracket.
  • the air outlet device since the air outlet device is disposed above the oil smoke pollution source, the positive pressure airflow blown downward by the air outlet device changes direction after hitting the oil smoke pollution source farther from the air suction port, and instantaneously mixes the pollution source oil smoke to the In the gas flow, the residence time of the pollution source soot is reduced, and the pollution source is prevented from spreading and overflowing.
  • the invention has a simple structure and low manufacturing cost.
  • Figure 1 is a schematic view showing the structure of a gas flow direction-driven soot removal device
  • Figure 2 is a front view of the airflow directionally driven soot removing device of Figure 1.
  • Figure 3 is a left side view of the airflow directionally driven soot removing device of Figure 1.
  • Figure 4 is a schematic diagram of the working principle of the airflow directionally driven soot removal device
  • the airflow direction-driven soot removing device is mainly composed of a chassis 1, an air suction device 4 provided inside the chassis 1, an air suction port, and the like.
  • a pot 2 is disposed on the upper end surface of the chassis 1 , and the pot 2 forms a source of oil smoke pollution.
  • One side of the soot pollution source is provided with an air suction port 10 , and the air inlet 10 is connected to the air suction device 4 through the pipe 13 , and the air suction device 4
  • the air outlet 11 passes through the side wall of the chassis 1.
  • the duct 13 is shaped as a hollow, square cylinder, and is mounted on the side wall of the chassis 1.
  • a bracket 12 is mounted above the duct 13, and the bracket 12 is transversely The surface is in the shape of a "7", and an air outlet device 3 is mounted at the end of the "7" shape corresponding to the top of the pot 2.
  • the distance between the air outlet device 3 and the upper end surface of the pot 2 is about 0.5 to 1 meter. This not only ensures the convenience of cooking and the like, but also makes the soot absorption more thorough (the working principle of the airflow direction-driven soot removal device will be detailed below).
  • the projection of the air outlet device 3 on the upper end surface of the pan 2 is located at the edge of the pan 2 and is opposite to the suction port 10.
  • Figure 4 shows the working principle of the airflow directionally driven soot removal device, wherein the arrow 100 shows the direction of the airflow coming out of the air outlet device 3, the arrow 200 shows the direction of the pollution source soot, and the positive pressure of the air outlet device 3 blown downward.
  • the airflow hits the wall of the pot 2 farther from the suction port, the direction is changed, and the pollution source soot is mixed into the airflow in an instant (to prevent the diffusion of the soot molecules), and flows to the suction port 10, near the suction port 10 It merges with the negative pressure airflow of the air inlet 10 to jointly drive the oil smoke into the air inlet 10.
  • the positive pressure generated by the air outlet device 3 suppresses the diffusion of the soot due to the rise of the hot air flow and the molecular thermal motion, reduces the overflow of the soot, thereby eliminating the soot more effectively than the simple negative pressure, and since the air outlet device 3 is disposed in the pot Above the 2, it will not affect the operator, the operation is very convenient, the structure is simple, and the manufacturing cost is low.

Abstract

L'invention concerne un appareil d'élimination d'huile et de fumée actionné par un flux d'air orienté et comprenant une ouverture d'aspiration (10) disposée du côté de sources de pollution constituées d'huile et de fumée (2), un dispositif d'aspiration (4) connecté à l'ouverture d'aspiration (10) par un conduit (13), et un dispositif d'alimentation en air (3) disposé au-dessus des sources de pollution constituées d'huile et de fumée (2). Un flux d'air à pression positive soufflé vers le bas par le dispositif d'alimentation en air (3) change sa direction d'écoulement après avoir rencontré les sources de pollution constituées d'huile et de fumée (2). L'huile et la fumée sont mélangées au flux d'air et évacuées par l'ouverture d'aspiration (10), ce qui permet de réduire le temps de résidence de l'huile et de la fumée, ces dernières ne pouvant ni se répandre ni s'échapper.
