The unexplained numeral "110" represents a connection terminal disposed at one side of the support frame 10 of the present invention for connecting several electric wires. The unexplained numeral "120" represents a condenser disposed at one side of the support frame 10 of the present invention .

As shown in FIG. 2, the elevating-type kitchen range hood of the present invention as described above comprises the support frame 10 of a predetermined size so that it can be supportably secured to the wall surface or ceiling of the kitchen, which acts as a support for securing the blower 24 mounted at the upper side of the body 20. Also, the support frame 10 is provided with a connection terminal 110 and a condenser 120, and the like to which several electric wires 100 are connected for supplying the electric power to the blower 24 and the motor 25, and for blinking the lighting L disposed at the lower side hood frame 60. Accordingly, in the present invention, the connection terminal 110 to which the blower 24, the motor 25 and the several electric wires 100 are connected complicatedly, and the condenser 120 are prevented from the exposure to the outside by disposing the support frame 10 to be inserted into the inside of the ceiling so that it is not exposed to the outside, or by disposing an outer cover enclosing the support frame 10 when it is secured to the wall surface.

Meanwhile the body 20 secured to the support frame 10 is shown to be rectangular in the appending drawings, however, it can be shaped in any outer appearances such as rectangular or cylindrical shape, and the like, with predetermined length in the vertical direction, which is formed with the through-hole 21, so that the elevating portion 30 is inserted into the body 20 and can be elevated,

As shown in FIG. 3, the control panel 22 disposed at the lower end of the body 20 is to control the elevating portion 30 inserted to the body 20 through the through-hole

21, which comprises several switches used widely, such as a general electric power on/off switch, an ascending

/descending switch, an emergency stop switch, a lighting switch, and the like, and controls the operations by coupling them with the blower 24, the motor 25 and the lighting L.

Meanwhile, the ascending/descending height of the elevating portion 30 is made to be limited by the limit switch 34 disposed at the control panel 22. Explaining it more concretely, the limit switch 34B disposed at the inside of the control panel 22 intercepts the electric power to thereby stop the motor 25 by contacting the step potion 32 formed at the lower end thereof with the descending limit switch 34B when the elevating portion 30 inserted into the body 20 is descended.

Further, the ascending limit switch 34A projects toward the lower surface of the control panel 22 so that the hood plate 40 disposed at the lower end of the elevating portion 30 is ascended to contact with it to thereby stop the motor 25.

Meanwhile, the ascending/descending of the elevating portion can be constructed to be operated by one-touch by means of the limit switch 34. In this regard, the elevating portion 30 ascended by means of the operation switch, descends continuously to be contacted with the descending limit switch 34B to thereby be stopped, and when the operation switch is pressed again to the contrary, the elevating portion 30 continuously ascends to be stopped when it contacts with the ascending limit switch 34A.

Such one-touch operation of the limit switch 34 is only an example, and it can be constructed to merely limit the ascending/descending height.

Meanwhile, the elevating portion 30 uses the rotation force of the motor 25 disposed at the upper side, so that the elevating portion 30 can ascend/descend in the upper and lower directions through the body 20. This can be controlled in the forward and reverse directions, and the elevating portion 30 coupled to the motor 25 by means of the interlocking means 70 can be ascended and descended.

As shown in FIG. 4, the electric wire 7OA, which is an example of the interlocking means 70, connected to the rotation shaft 25A of the motor 25 becomes to rotate in the forward or reverse direction by means of the rotation of the motor 25, so that the electric wire 7OA can be wound or released. Also, the lower end of the electric wire 7OA is secured to the binding plate 33, so that the elevating portion 30 can be ascended and descended by the operation of the winding and releasing of the electric wire 7OA.

Accordingly, as shown in FIG. 5, the chain 7OB can be provided as for another example of the interlocking means to interlock the motor 25 with the elevating portion 30. When the gear 25B of a predetermined size is bound to the rotation shaft 25A of the motor 25, the chain 7OB becomes to rotate in the forward and reverse directions by means of the rotation of the gear 25A, and the lower side of the chain 7OB is secured to the binding plate 33so that the length of it becomes to be longer or shorter by the rotation of the chain 7OB to thereby make the elevating portion 30 ascended or descended. As for the examples of the interlocking means 70, while the electric wire 7OA and the chain 7OB have been explained, however, it can be modified and substituted in various manners and types so that those people skilled in the art can implement it easily.

As regard to the elevating portion 30 ascending/descending as described above, and the body 20 for guiding the elevating portion 30, the hairy portion M of predetermined length is provided at the inside peripheral surface in the through-hole 21 of the body 20, so that it can remove the soot, the fine dust, and the like attached at the outer peripheral surface of the elevating portion 30.

The hairy portion M is merely an example of the present invention, and it can be modified to be an airtight maintaining means such as a rubber packing, and the like, so that those skilled in the art can easily implement it.

Meanwhile, as shown in FIG. 6, the hood plate 40 provided at the lower end of the elevating portion 30, is formed to have a predetermined width and a length from the right to the left, covering a fuel intake of the gas range, and the smoke and the food smell can be flowed into the blowing inlet 31 of the elevating portion 30 via at least one of the grill G provided to the hood frame 60 disposed at the lower surface of the hood plate 40.

The strong suction force toward the upper side is acted on the inside of the blowing inlet 31 due to the blower 24. Accordingly, smoke and the food smell flowed into the grill G can be quickly sucked into the upper side of the range hood to thereby be discharged to the outside by means of the blower 24. Also, in an embodiment of providing the grill G to the present invention, a filter can be further provided to remove several alien materials flowed into side of the blower 24. Meanwhile, although the electric wire 100, which is provided to blink the lighting L of the hood frame 60, is constructed to have a predetermined marginal length in order to prepare the descending of the elevating portion 30, however, as shown in FIG. 7, the electric wire control device 50 is provided in the present invention at the rear side of the body 20 for winding and releasing the electric wire automatically according the ascending and descending of the elevating portion 30.

The electric wire control device 50 is constructed to apply elastic force for continuously winding the electric wire by using the electric cord of the housing electric device such as a vacuum cleaner or a tapeline as the elastic coil, so that it can be wound automatically. This is to implement selectively what has been implemented widely in the art, after the people skilled in the art have selected it to provide in the present invention. So, concrete description thereof will be omitted.

Meanwhile, in the preferred embodiment of the present invention, while the lighting L is provided to the hood frame 60, the present invention can be constructed in other ways such that an infrared ray lamp is provided in addition to the lighting L to produce the infrared ray, or a thermal sensor is provided to operate the elevating portion automatically during the cooking. Furthermore, it is preferable that the electric wire 100 for connecting the whole parts of the present invention is connected and finished at the inside of a groove portion, which has been formed so that it is not limited by the ascending and descending of the elevating portion 30 and is not exposed to the outside.

Accordingly, the present invention is characterized by comprising the body 20 and the elevating portion 30 for the ascending and descending of the range hood, the interlocking means 70 for ascending/descending the elevating portion 30, and ascending/descending limit switches 34A, 34B as the limit switch 34 for defining the height of the elevating portion 30 in the upper and lower sides .
