Abstract

PURPOSE:To provide an air purifying equipment capable of drawing an oily hume developed by a source in a cooking utensil and the like positively into an air purifying section for efficiently removing the oily hume, by proving to it an air curtain. CONSTITUTION:When a fan motor 2 is started during cooking, with an oily hume developing unit 6 located at a portion 10 where an air curtain developing unit is installed, an air flows passing through a dust collecting section 3 and enters partially into an air venting tube 7 through an opening 11 and a communicating tube 4, wherefrom it is exhausted through a slit 8 for forming an air curtain. The air curtain functions to guide an oily hume moving upwardly from the oily hume developing unit 6 into a center of air purifying equipment 1. The oily hume, after being drawn by a fan motor 2 and separated by a dust collecting section 3, has its clean air exhausted upwardly from a partial air exhaust outlet 9 and another part thereof guided into an air curtain developing section 5 through a communicating tube 4 for forming the air curtain.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air purifying device that removes oily smoke generated when eating grilled meat or other food while cooking on a table.

In recent years, there has been an increase in the tendency to eat while cooking on cooking tables, etc., and this has spread to hot plates, but the oil smoke generated during cooking fills the room, causing oil and odor to stain furniture and curtains. Because of the drawback of air pollution, there is a desire to develop a small and inexpensive air purifying device.

One way to solve this problem is to install an air purifier on the table, but the oil smoke from cooking spreads as it rises, and can also be blown sideways by the indoor wind. In order to reliably suck in oily smoke, the foot of the air purifier becomes extremely large. Therefore, if you try to make it to a practical size, you will have to place it close to the cooker, which in this case will interfere with eating around the table and will not be practical. There was one problem: it became something that could not be included. Although there is demand for these products, the reality is that technically appropriate product development has not been achieved.

The present invention solves the above-mentioned conventional problems, and one embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1Q-1 is an air purifying unit containing a fan motor 2, and below the fan motor 2, a removable and replaceable dust collection unit 3 is added. 4d is a communication pipe that supports the air purifier 1 in an upper position and conducts part of the exhaust gas downward, and the lowermost part communicates with the annular air curtain generator 6. The air curtain generator 6 forms an air vent pipe 7 so as to surround a smoke generator 6 such as a cooking device. Ventilation pipe 7
A plurality of slits 8 for blowing out air toward the suction surface of the dust collecting section 3 of the air purifying section 1 are formed on the inner upper surface of the air purifying section 1 . Reference numeral 9 denotes an air loss port provided on the soil surface of the air purifying section 1. 10 is the installation part of the oil smoke generator 6 formed in the medium heat part of the central part 5 of the air curtain generating part 5, which has four parts,
The oil smoke generator 6 can be freely installed here.

The opening 11 of the communication pipe 4 is located at the radiation line of the fan of the fan motor 2 in the air purifying section 1Vc, and the exhaust port 9 is located in a direction perpendicular to this opening 11. be. 1. The slope of slit 8 is a.
The angle θ1 between the line connecting the slit 8 and the front and rear ends of the dust collecting section 3 and the horizontal direction. It is set so that the relationship 01≦(L≦02) is established with θ2.

In the above configuration, the operation of the air purifying device will be explained. When the oil smoke generator 6 such as a cooking device is placed on the installation part 1o of the air curtain generation part 5 and the fan motor 2 is started while cooking, the air passes through the dust collection part 3 and a part of the air flows through the opening 11 into the communication pipe. 4, enter the ventilation pipe 7, and enter JJJ from the slit 8.
+ is ejected to form an air curtain. Thereby, the oil smoke rising from the oil smoke generator 6 is guided toward the center of the air cleaning section 1.

After the oil smoke is sucked in by the drive of the fan motor 2 and separated in the dust collecting section 3, a part of the clean air is exhausted upward from the exhaust ``]9, and a part passes through the communication pipe 4 to the air. The air is guided to the curtain generating section 6 to form an air curtain.

Here, the air pressure of the air curtain that guides the oil smoke to the air purifying section 1 flows out due to the centrifugal force of the fan of the fan motor 2, so air with strong wind pressure is obtained, while the air flowing out from the air loss port 9 Since the flow is reversed in the centrifugal direction of the fan, there is no problem in the use of weak flow.

As described above, according to the present invention, the oil smoke generated from the oil smoke generator such as a cooking appliance is reliably guided to the air cleaning section by the air curtain, and efficient oil smoke removal is achieved. Also, oil smoke d
Since the air does not diffuse but rather rises while being concentrated in the center, the air purifier can be made smaller than a cooking device, etc., so it has excellent effects such as being able to have a configuration that does not become a clutter when cooking. is playing.

In addition, if the air curtain generation part is divided into four parts as in the example, the center part is used as the installation part for cooking appliances, etc., so it can be used as a smoke remover for various devices, and if an ashtray is placed, it can be used to remove cigarette smoke. It can also be used as a vessel. Furthermore, the air curtain generating section itself can be integrated with equipment such as a cooking machine.
