Abstract

The utility model relates to an air curtain type smoke exhaust ventilator, in particular to a structure which can be combined into a whole by matching with two air flowing modes, wherein, an air supply fan, an air filter screen positioned above the air supply fan and more than two fences arranged below the air supply fan are arranged at the front end of a smoke collecting hood of the smoke exhaust ventilator, the wind blown out by the air supply fan can form two air curtains by virtue of the fences, wherein, one air curtain is positioned at the front end and blows from top to bottom so as to prevent the oil smoke which floats from bottom to top from floating outwards; the other air curtain blows from the upper part to the inclined rear part, and the formed air flow can induce the oil smoke to enter a smoke collecting chamber of the oil smoke exhauster and then is exhausted out of the room through a fan, so that the aims of preventing kitchen workers from sucking the oil smoke and ensuring the cleanness of a kitchen are fulfilled.

Description

Air Curtain Range Hood

technical field

The utility model relates to an air curtain type range hood, in particular to a structure that combines two air flow modes into one, mainly composed of a ventilation device that sucks in air power and a ventilation device that sends out air power. 1. Installer of ventilation equipment.

Background technique

Chinese cooking methods always like steaming, boiling, and frying, so a lot of oily smoke and water vapor will be generated. In order to prevent the oily smoke from filling the room, almost every family will install a range hood in the kitchen, as shown in Figure 2 It is a schematic diagram of the structure of a general range hood. A general range hood adopts the principle of inductive exhaust to exhaust the oil fume to the outside, and uses a large amount of air (air) to collect the oil fume in the hood by the fume collecting hood 50, and then uses the exhaust fan 51 sucks the oil fume in the fume collecting hood 50 into the air box 52, and exhausts it to the outside through the fume exhaust outlet 53.

Yet existing range hood has following deficiency:

1. In order to avoid obstructing the line of sight, generally the range hood is installed above the height of the eyes. In this way, the oil fume generated by the high temperature will pass through the face of the person before reaching the fume collecting hood 50, which will be inhaled by the cook and affect the Respiratory health.

2. Since the fume collecting hood 50 is too high, there is still a certain distance to the pot, so it is easy for the oil fume to float away before reaching the fume collecting hood 50, which not only endangers the respiratory organs of the kitchen staff, but also makes the kitchen utensils and utensils that the oil fume adheres to The walls are difficult to clean.

Contents of the invention

In view of the various shortcomings of the existing range hoods, the utility model designer of the present utility model has studied carefully, hoping to achieve a range hood that reduces the fume from floating around and being sucked by the human body.

In order to achieve the above object, the main technology of the present utility model is to provide an air curtain type range hood, which includes a casing and a row of fans. A smoke collecting hood extending forward from the top of the bellows and the smoke collecting chamber, the exhaust fan is arranged on the front peripheral wall of the bellows, and the front peripheral wall of the bellows is correspondingly located at the exhaust fan, and is provided with an upper suction port, which is characterized in that:

The front peripheral wall of the smoke collecting chamber is provided with a lower suction port located below the upper suction port;

In addition, a blower fan is arranged at the front end of the smoke collecting hood, and more than two fences are arranged below the blower fan.

After implementing above-mentioned technical means, the concrete benefit that the utility model can obtain is:

Since the utility model is provided with a lower suction port below the upper suction port, and a blower fan and a fence are arranged on the smoke collection hood, the fence at the front end can guide the wind blown by the blower fan downward, and close to the smoke collection room. The fence on the side mentioned above guides the wind to the suction port at the bottom. Therefore, when the oil fume rises from the bottom, the wind generated by the blower fan can generate two air curtains through the fence, and one of the air curtains can block the oil fume from going up. The other air curtain plays an inductive role, attracting the oil fume through the flowing air curtain, entering the smoke collection chamber through the suction port at the lower end, and then exhausting it outside through the exhaust fan.

Therefore, the utility model can truly achieve the purpose of preventing kitchen workers from inhaling cooking fume and keeping the kitchen clean.

Detailed ways

In order to enable your examiner to have a further understanding and understanding of the structural features and functions of the air curtain type range hood described in this case, hereby cite a feasible embodiment and describe it in detail as shown in Figure 1. In the following description, the so-called " "Front side" means the side facing the fire for cooking:

The air curtain smoke exhauster provided by the utility model includes:

A casing 1, the casing 1 includes a bellows 10, a smoke collection chamber 13 located in front of the windbox 10, a smoke collection hood 15 extending forward from the top of the bellows 10 and the smoke collection chamber 13, the said The top peripheral wall of the bellows 10 is provided with a smoke exhaust outlet 11, and the front peripheral wall of the smoke collection chamber 13 is provided with an upper suction port 130, and a lower suction port 131 below the upper suction port 130, and a bottom suction port 131 is provided at the bottom of the smoke collection chamber 13. Oil pan 133;

A row of fans 20 is installed on the front peripheral wall of the bellows 10, and correspondingly located at the upper suction port 130, the exhaust fan 20 has a suction port 21 towards the cooking position, and an oil collecting net 25 is installed on the suction port 21;

A blower fan 40 is arranged above the front end of the smoke collecting hood 15, and a guided air outlet 150 located below the blowing fan 40 is provided on the smoke collecting hood 15, and two groups of air outlets are arranged on the guided air outlet 150. A set of fences 151 that can adjust the air outlet angle is convenient for adjusting the angle of the air curtain sent by the fan 40, so that the oil fume rising from the bottom can be correctly introduced into the lower suction port 131, and then the oil fume is sucked into the bellows 10 through the exhaust fan 20, and then It is exhausted from the smoke exhaust outlet 11, and the oil fume remaining in the smoke collection hood 15 is discharged by means of the upper suction port 130; and a set of grilles 151 can form an air curtain type air curtain to prevent part of the air from rising and drifting The oil fume escapes.

In addition, an air inlet is provided above the blower fan 40, and the outside air is sucked in. Preferably, an air filter 41 is set on the air inlet, which can ensure that a clean and fume-free air is sent out by the blower fan 40, so that it can be used by the staff. A top-to-bottom air curtain is formed between the oil fume areas, which can really prevent the staff from inhaling the oil fume.

The above description is only illustrative of the present utility model, rather than restrictive. Those of ordinary skill in the art understand that many modifications, changes or equivalents can be made without departing from the spirit and scope defined in the claims. But all will fall within the limitable scope of the claims of the present utility model.
