Definitions
- the present invention relates to an exhaust hood, and particularly, to an exhaust hood having an improved efficiency for collecting contaminated air.
- an exhaust hood is disposed above a cooker such as a gas range or a laboratory table that generate materials causing air pollution like smoke, smells and grease vapor.
- FIG 1 is a side sectional view that illustrates one example of an exhaust hood according to the conventional art.
- the conventional exhaust hood includes a canopy 21 installed above a cooker 10 having a plurality of burners 11a and 11b spaced at a predetermined distance therebetween, and an exhaust part 31 communicating with the canopy 21 and upwardly protruding from the canopy 21 to a predetermined height.
- An inlet 23 is formed at the bottom of the canopy 21, through which the polluted air including pollutants like smoke, smells and grease vapor generated from the cooker 10 is drawn in. Also, a grease filter 24 that can collect pollutants is mounted at the inlet 23.
- An exhaust path 33 is formed in the exhaust part 31, through which the polluted air having been introduced through the inlet 23 is exhausted to the outside.
- An exhaust fan 34 for forcibly taking in the air is installed under the exhaust path 33.
- the polluted air including smoke, smells and grease vapor generated as burners 11 a and 11 b of the cooker heat food items is in a buoyancy jet form and increases in width as it ascends.
- a method of increasing a rotation rate of the exhaust fan 34 and thusly increasing an intake force may be used.
- the rotation rate of the exhaust fan 34 is increased to increase the intake force, the intake performance is not improved in proportion to the increased rotation force. For this reason, only the intake force of the exhaust fan 34 used in such a method is not enough to guide the polluted air, which is moved to outside along the bottom surface of the canopy 21, to the inlet 23.
- the conventional exhaust hood cannot prevent the polluted air from moving out from the canopy 21, polluting an upper region (A) of the front side of the canopy 21 and spreading to a room to thus pollute a surrounding environment.
- FIG 2 is a side sectional view that illustrates another example of a conventional exhaust hood.
- the conventional exhaust hood in accordance with another example includes a hood body 51 disposed above a cooker 10 at a predetermined distance therebetween, and a nozzle part 81 installed at a front region of the hood body 51 and downwardly discharging the air.
- the hood body 51 includes a canopy 61 installed above the cooker 10, which has a plurality of burners 11a and 11b, at a predetermined distance therebetween, and an exhaust part 71 communicating with the canopy 61 and upwardly protruding from the canopy 61 to a predetermined height.
- the nozzle part 81 is formed at a front region of a bottom surface of the canopy 61 and discharges the air downwardly.
- An air supply fan 83 for blowing the air to the nozzle part 81 is installed in the canopy 61.
- a curve shape portion 85 having an arc shaped section which is convex downwardly is formed at a lower side of the front surface of the canopy 61, so that a portion of the air discharged through the nozzle part 81 can flow to a region of the inlet 63 by the so-called coanda effect.
- the curved shape portion 85 the polluted air cannot be moved outside the canopy 61 but is guided to the inlet 63.
- the nozzle part 81 is formed at a spot inwardly spaced apart from the front end of the canopy 61 at a predetermined distance.
- the polluted air having ascended inside the canopy 61 can be guided to the inlet 63 by the air discharged through the nozzle part 81.
- the method does not solve the problem that the polluted air ascending to the front end of the canopy 61 is moved out from the front end of the canopy 61 and pollutes an upper region (B).
- an object of the present invention is to provide an exhaust hood having an improved collecting efficiency of contaminated air
- an exhaust hood comprising: a hood main body 110 provided with a canopy 111 having an inlet 117, and an exhaustion portion 121 connected to the canopy 111 and having an exhaustion passage 123; and a nozzle unit 140 disposed at a front side of the hood main body 110, and provided with a curved shape portion 141, and a nozzle 143 disposed at an upper side of the curved shape portion 141 along a circumferential direction of the curved shape portion 141 for horizontally discharging air toward a front region of the curved shape portion 141.
- Fig. 3 is a perspective view showing an exhaust hood in accordance with a first embodiment of the present invention
- Fig. 4 is a sectional view taken along a line IV-IV of Fig. 3
- Fig. 5 is an enlarged view of a part C of Fig. 4.
- an exhaust hood in accordance with a first embodiment of the present invention may include a hood main body 110 and a nozzle unit 140 disposed at a front side of the hood main body 110 for discharging air.
- a nozzle unit 140 disposed at a front side of the hood main body 110 for discharging air.
- Each arrow indicates an air flow.
- the hood main body 110 may include a canopy 111 disposed at an upper side of the cookware 10 (refer to Fig. 1) with a particular distance therebetween, and an exhaustion portion 121 connected to the canopy 111 and protruding to the upper side of the canopy 111 by a particular height.
- the canopy 111 has a rectangular plate shape, and is provided with an inlet 117 disposed at a lower surface of the canopy 111 for sucking air and a grease filter 118 mounted in the inlet 117 for filtering contaminated materials.
- An air supply fan 135 for blowing air to the nozzle unit 140 and an air supply motor 136 for driving the air supply fan 135 are disposed in the canopy 111.
- a partition wall 131 for partitioning an inside of the canopy 111 is formed at a right side of the air supply motor 136 and the air supply fan 135.
- a suction hole 133 for partially sucking the air passed through the grease filter 118 to the air supply fan 135 is formed at the partition wall 131.
- An exhaustion passage 123 for discharging the air from which the contaminated materials are filtered by the grease filter 118 is formed at the exhaustion portion 121.
- An exhaustion fan 124 for forcibly sucking air and an exhaustion motor 125 for driving the exhaustion fan 124 are mounted at a lower side of the exhaustion passage 123.
- the nozzle unit 140 may include a curved shape portion 141, and a nozzle 143 disposed at an upper side of the curved shape portion 141 along its circumferential direction for horizontally discharging air toward a front region of the curved shape portion 141.
- the curved shape portion 141 has a cylindrical bar or cylindrical pipe shape of which circular section has a diameter of 40 to 65 mm.
- a ratio (h/D) of a distance (h) between a center O of the curved shape portion 141 with respect to the diameter D thereof and a lower surface 111 b of the canopy 111 can be 0 to 0.5.
- the nozzle 143 is formed at an upper surface of the curved shape portion 141 to thus horizontally discharge air toward the front region of the curved shape portion 141.
- the nozzle 143 is spaced from the upper surface of the curved shape portion 141 by a gap (d) corresponding to about 1.5 to 4 mm.
- An internal angle ⁇ formed between a virtual line L1 for connecting an end of the nozzle 143 to the center O of the curved shape portion 141 and a vertical line Lv passing through the center O of the curved shape portion 141 is preferably 0 to 30° to maximize a coanda effect.
- the air from which the contaminated materials are filtered is partially sucked in the suction hole 133.
- the sucked air is horizontally discharged toward the front region of the curved shape portion 141 through the nozzle 143 via the air supply passage 137.
- the air horizontally discharged through the nozzle 143 flows along the upper surface of the curved shape portion 141 to form a negative pressure region S1 having a minus (-) gauge pressure at the upper and front surfaces of the curved shape portion 141.
- a progressive path of the contaminated air which is intended to pass through the exhaust hood is curved toward the negative pressure region S1 and thus the contaminated air is induced to the inlet 117 again. Accordingly, a collecting efficiency of the exhaust hood can be improved.
- Fig. 6 is a perspective view showing an exhaust hood in accordance with a second embodiment of the present invention
- Fig. 7 is a sectional view taken along a line VII-VII of Fig. 6.
- an exhaust hood according to a second embodiment may further comprise a flow guide 170 disposed at one side of the nozzle unit 140 for guiding an air flow and restraining a vortex formation caused by a flow separation.
- the flow guide 170 may include a guide portion 173 extending horizontally in a width direction of the curved shape portion 141 and having an arc-sectional shape, and a support portion 175 formed at both sides of the guide portion 173, respectively, and mounted at both sides of the curved shape portion 141, respectively.
- the negative pressure region S1 extends up to the upper portion of the curved shape portion 141, but, on the other hand, the air is not moved downwardly up to the lower portion of the curved shape portion 141 but separated from the curved shape portion 141 at its middle portion. As a result, the vortex is formed, thereby decreasing the coanda effect.
- the flow guide 170 is disposed at the lower side of the curved shape portion 141 to guide the air flow downwardly up to the lower side of the curved shape portion 141 and to restrain the vortex formation caused by the flow separation, thereby maximizing the coanda effect.
- the air from which the contaminated materials are filtered is partially sucked in the suction hole 133.
- the sucked air is horizontally discharged toward the front region of the curved shape portion 141 through the nozzle 143 via the air supply passage 137.
- the air horizontally discharged through the nozzle 143 flows along the upper surface of the curved shape portion 141 to form the negative pressure region S1 having the minus (-) gauge pressure at the upper and front surfaces of the curved shape portions 141. Accordingly, the progressive path of the contaminated air which is intended to pass through the exhaust hood is curved toward the negative pressure region S1, and thus the contaminated air is induced to the inlet 117 again.
- the flow guide 170 disposed at the lower side of the curved shape portion 141 guides the air flow downwardly up to the lower surface of the curved shape portion 141. Accordingly, the vortex formation caused by the flow separation is restrained to thus maximize the coanda effect. Therefore, the collecting efficiency of the exhaust hood can be improved.
- Fig. 8 is a perspective view showing an exhaust hood in accordance with a third embodiment of the present invention
- Fig. 9 is a sectional view taken along a line IX-IX of Fig. 8.
- an exhaust hood according to a third embodiment may further comprise a flow plate 180 disposed at one side of the nozzle unit 140 for guiding an air flow and restraining a vortex formation caused by an flow separation.
- An installation purpose of the flow plate 180 is the same as the flow guide 170 shown in Fig 6 and the explanation therefor will thus be omitted.
- the flow plate 180 may include a plate portion 181 extending in a width direction of the curved shape portion 141 and spaced downwardly from the lower side of the curved shape portion 141 by a particular interval, and a connection portion 183 formed at both sides of the plate portion 181, respectively, and mounted at both sides of the curved shape portion 141, respectively.
- the plate portion 181 is disposed at the lower side of the canopy 111 with the particular interval therebetween such that a ratio (Db/D) between an interval Db between the lower surface 111b of the curved shape portion 141 and the plate portion 181 and the diameter D of the curved shape portion 141 can be 0.2 to 1.0 in order to guide the air to the maximum.
- An inflow guide portion 181a for facilitating a guiding of air to a space S2 formed between the curved shape portion 141 and the plate portion 181 is formed to have a curved surface at a front end of he plate portion 181.
- the inflow guide portion 181 a is formed at the front end of the plate portion 181 such that a ratio (Da/D) between the interval Da between the vertical line Lv passing through the center O of the curved shape portion 141 and the inflow guide portion 181 a and the diameter D of the curved shape portion 141 can be 0 to 0.5, thereby guiding the air to the maximum.
- the air from which the contaminated materials are filtered is partially sucked in the suction hole 133.
- the sucked air is horizontally discharged toward the front region of the curved shape portion 141 through the nozzle 143 via the air supply passage 137.
- the air horizontally discharged through the nozzle 143 flows along the upper surface of the curved shape portion 141 to form the negative pressure region S1 having the minus (-) gauge pressure at the upper and front surfaces of the curved shape portions 141. Accordingly, the progressive path of the contaminated air which is intended to pass through the exhaust hood is curved toward the negative pressure region S1, and thus the contaminated air is induced to the inlet 117 again.
- the flow plate 180 disposed at the lower side of the curved shape portion 141 guides the air flow downwardly up to the lower side of the curved shape portion 141, and thus restrains the vortex formation caused by the flow separation, thereby maximizing the coanda effect.
- Fig. 10 is a lateral sectional view showing an exhaust hood provided with an upper inlet in accordance with a fourth embodiment of the present invention.
- the air sucked through the grease filter 155 disposed in the upper inlet 153 formed at an upper surface 111a of the canopy 111 is supplied as air to be discharged through the nozzle 143.
- Fig. 11 is a lateral sectional view showing an exhaust hood provided with a reflux flow path in accordance with a fifth embodiment of the present invention.
- the air which is intended to pass through the exhaustion passage 123 is partially supplied as air to be discharged through the nozzle 143 in the fifth embodiment.
- a reflux flow path 161 of which one end is connected to the exhaustion passage 123 and the other end is connected to the air supply passage 137 is formed in both the canopy 111 and the exhaustion portion 121. Accordingly, the air supply fan 135(refer to Fig. 4) and the air supply motor 136(refer to Fig. 4) are not required any more, and thus fabricating cost therefor can be reduced.
- Fig. 12 is a perspective view showing an exhaust hood provided with a supplementary nozzle unit in accordance with a sixth embodiment of the present invention.
- an exhaust hood may comprise the nozzle unit 140 for preventing contaminated air from flowing toward the front region of the canopy 111 without being sucked therein, and a supplementary nozzle unit 190 for preventing the contaminated air from flowing toward each lateral region of the canopy 111 without being sucked therein.
- the supplementary nozzle unit 190 may include a lateral curved shape portion 191, and a lateral nozzle 193 disposed at an upper side of the lateral curved shape portion 191 along its circumferential direction for horizontally discharging air toward a front region of the lateral curved shape portion 191.
- the construction and operation of the lateral curved shape portion 191 and the lateral nozzle 193 of the supplementary nozzle unit 190 are the same as the curved shape portion 141 and the nozzle 143 of the nozzle unit 140, and thus the explanation therefor will be omitted.
- the supplementary nozzle unit 190 can allow the contaminated air flowing toward the lateral region of the canopy 111 to be collected, and accordingly the overall collecting efficiency of the exhaust hood can be improved.
- the curved shape portion and the nozzle for horizontally discharging air toward the front region of the curved shape portion are provided such that the contaminated air flowing toward the front region of the exhaust hood without being sucked therein can effectively be induced to the inlet to thus be collected. Therefore, more comfortably cooking circumstance and experimental environment can be created.
- the air flow can be guided downwardly up to the lower surface of the curved shape portion. Accordingly, the vortex formation caused by the flow separation can be restrained to thereby improve the collecting efficiency of the exhaust hood.
