2. Description of the Prior Art

Generally speaking, a considerable amount of fumes are dispersed into the air in most household range or stove-top cooking so that the fumes with strong odor often fill the inside and are easily attached to the surfaces of the indoor walls, furniture and articles with difficulty in cleaning.  It is known in many medical reports that such fumes are bad to human body and, even worse, liable to cause lung cancer after being contacted for a long time, thus bringing great damage in human health.

Therefore, many conventional fume exhausters are used in kitchens to exhaust fumes that are generated in cooking. However, most of the conventional fume exhausters are mounted in a stationary way on ambient walls of the kitchens at a predetermined distance above cooking stoves and cooking appliances so that it is impossible for users to freely adjust the height and position of the conventional fume exhausters to meet with their individual needs, thus greatly limiting the exhausting effect of the conventional fume exhausters without exhausting the fumes thoroughly out of a cooking environment.

SUMMARY OF THE INVENTION

The main purpose of the present invention is to offer a fume exhaust apparatus for cooking stoves, which can efficiently exhaust fumes that are generated in cooking thoroughly out of a cooking environment.

The primary feature of the present invention is to provide a fume exhaust apparatus for cooking stoves mainly including:a fixing base;a connection assembly pivotally mounted on the fixing base;a transparent hood assembled with a lower end of the connection assembly, and having a heat-insulation handle and a through hole respectively disposed thereon;a fume-exhaust hose having one end connected to the through hole of the transparent hood and the other end connected to a filter box and an air-suction motor; and,the air-suction motor capable of being connected with a control  switch via a power-supply cord, and having one side connected with an air-exhaust tube.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

A preferred embodiment of a fume exhaust apparatus for cooking stoves in the present invention, as shown inFIG. 1, mainly includes a fixing base1, a connection assembly2, a transparent hood3, a fume-exhaust hose4, a filter box5and an air-suction motor6.

The connection assembly2pivotally mounted on the fixing base1includes a swivel arm21having one end pivotally mounted on the fixing base1and the other end provided with a swivel pivot22whose lower end is pivotally connected with one end of a connecting rod23whose the other end is pivotally connected with an upper end of a supporting rod24.

The transparent hood3capable of being assembled with a lower end of the supporting rod24of the connection assembly2has a heat-insulation handle30, an opening31and a through hole34respectively disposed thereon. The opening31is capable of being pivoted with a door32that is provided with a grip33disposed thereon.

The fume-exhaust hose4has one end connected to the through hole34of the transparent hood3and the other end connected to the filter box5.

The filter box5is provided with an air inlet50disposed at one side thereof for connecting the other end of the fume-exhaust hose4and an air outlet51disposed at the other side thereof for connecting one end of an air-suction tube40whose the other end is connected with the air-suction motor6.

The air-suction motor6capable of being connected with a control switch61via a power-supply cord60has one side connected with an air-exhaust tube41and the other side connected with the air-suction tube40.

After the fixing base1, the filter box5and the air-suction motor6are respectively secured to a wall, the transparent hood3is assembled with the connection assembly2in suspension ready for use.

In using, referring toFIGS. 1 and 2, firstly a user can adjust the position of the transparent hood3to correspond the positions of a cooking stove7and a cooking vessel8only by holding the handle30of the transparent hood3with one hand to move the transparent hood3. When the transparent hood3is moved, the connection assembly2is movable  by having the swivel arm21swiveled around the fixing base1and the connecting rod23swiveled around the swivel pivot22in a position below the swivel arm21. Moreover, by the pivotal connection with the swivel pivot22, the connecting rod23is allowed to rotate upwards or downwards. In such way, the transparent hood3can be moved to any required positions, e.g. to be positioned at a proper distance above the cooking vessel8, as shown inFIGS. 2,3and4.

Secondly, when the user intends to cook the food, he only needs to depress the control switch61to actuate the air-suction motor6with a required air-exhaust speed so that fumes generated in cooking can be drawn from the transparent hood3, through the fume-exhaust hose4and into the filter box5for filtering. And then, the filtered air can be exhausted outdoors via the air-exhaust tube41. Moreover, the transparent hood3is able to be adjusted in its position at any distance above the cooking vessel8, thereby enabling the fumes to be exhausted thoroughly out of a cooking environment.

Moreover, when the user intends to have the food or fishes pan-fried or deep-fried, he can move the transparent hood3downwards to be directly covered on the cooking vessel8to prevent hot oil that is generated in frying from being splashed out of the cooking vessel8, and then make the fumes that are generated together with the hot oil directly drawn into the filter box5via the fume-exhaust hose4for filtering and exhausting, as shown inFIGS. 3 and 4.

Furthermore, a main body of the transparent hood3is designed to be transparent for the convenience of observing the cooking condition of the food from the outside of the cooking vessel8. When the food is to be stirred, the user only needs to open the door32of the transparent hood3and extend a turner or a ladle (not numbered) into the cooking vessel8to  stir the food, as shown inFIG. 4. In case that the user is hard to stir the food when the transparent hood3is covered on the cooking vessel8, the user only needs to pull the transparent hood3upwards to be at a proper distance above the cooking vessel8, which is very easy and simple in operation.

When the transparent hood3is not in use after the food is cooked, referring toFIG. 5, the user only needs to pull the transparent hood3upwards and push it against the wall, by which the swivel arm21will be swiveled to be attached to the wall and the connecting rod23can be rotated upwards accordingly so as to be close to the swivel arm21, thereby allowing the transparent hood3to be deposited against the wall, thus enabling the fume exhaust apparatus of the present invention to be occupied only with little space, also very convenient in using and in collapsing.

The invention has the following advantages, as can be understood from the aforesaid description.

1. The fume exhaust apparatus of the present invention is simple in assemblage and convenient in operation. After the fume exhaust apparatus is installed on a wall in a position close to a cooking stove, the transparent hood3can be adjusted to move frontward, backward, upwards or downwards to any required positions for adapting to cooking stoves of various sizes and for using in different cooking ways.

2. The fume exhaust apparatus of the present invention can efficiently exhaust the fumes that are generated in cooking thoroughly out of a cooking environment to keep the inside clean such that users can be relieved from the suffering of the fumes to keep good health all the time.

3. When not in use, the transparent hood3of the present invention can be pulled upwards to be deposited against the wall for saving space.
