The specific embodiment
The present invention relates to a kind of Hood for kitchen, particularly relate to a kind of range hood with ambient air inlet, the air that has grease of cooking surface top can be drawn in the range hood so that be discharged to the outside by described air intake.
In Fig. 1～4, expressed the preferred embodiment of the ambient air inlet that is configured in the range hood 10.As Fig. 2 the most clearly shown in, this range hood has an outer cover 2, it limits top surface, front surface, rear surface and side surface, and forms the shell of a shroud.Usually this outer cover is made of the metal parts that is bent and weld together, so that form the shape of the similar box body shown in the accompanying drawing.
Motor shell 5 with top surface, basal surface and perimeter side surface of the air chamber that limits a sealing is installed in the range hood shroud.Preferably, motor shell is roughly cylindric, and has a top 14 and bottom 16 that links together.Motor 4 is installed in the top 14 of motor shell 5.Motor 4 and motor shell 5 are suitable for being removably mounted on the outer cover 2.Fan 6 detachably links to each other with motor 4.Being designed and sized to of this fan makes the interval minimum between the peripheral side wall of the radially outward edge of fan and motor shell.
Motor shell 5 has an air outlet slit 18 that is arranged in top 14.As shown in Figure 4, when motor shell 5 installation in position, air outlet slit 18 is outstanding by an opening in the top surface of outer cover, and roughly is centrally located between the described side surface.
Motor shell 5 also has at least one air intake 20 in bottom 16.Air intake 20 is positioned on the periphery of bottom 16.When a plurality of air intakes 20 are arranged in bottom 16, with intermediate member 21 air intake is separated, described intermediate member is used for bottom 16 is strengthened.
In order to form complete range hood shroud, range hood 10 has the periphery air intake framework panel 12 that is connected removably on the outer cover 2 and is connected to lower panel 8 on outer cover 2 and the framework panel 12 removably.Framework panel 12 comprises the top panel part 24 of a general plane shape, and it has a periphery wall 28 and an outward flange 30 that depends on it.Flange 30 is provided with one and is used for framework panel 12 is connected on the outer cover 2 and lower panel 8 is connected to edge on the framework panel 12.These connections preferably realize by quick release bolt 26.When the framework panel was connected on the outer cover 2, the top panel part was recessed from the lower limb of range hood.
The shape of framework panel 12 makes a part that it can be by making periphery wall 28 and the mode of motor shell 5 adjacency install round motor shell 5.Air intake 20 in opening 23 on the periphery wall 28 and the bottom 16 of motor shell 5 is in size, corresponding in shape, and aligns with it.Similarly, intermediate member 27 aligns with intermediate member 21.Preferably, as illustrating best in Fig. 3 and 4, opening 23 is connected with corresponding periphery air intake 20.
When greasy air passed through motor shell, some greases condensed upon on inner surface and the framework panel 12.When needed, the grease on the framework panel 12 can be wiped at an easy rate.Grease in the motor shell is discharged to the bottom of motor shell.The basal surface of motor shell recedes in the past, so that its lip-deep liquid row also drains into by flexible pipe 42 in the outside lubricating cup 22 then to osculum 40.
For the ease of clearing up, a plurality of cleaning fluid distributors can be installed in motor shell.Described cleaning fluid distributor preferably includes the nozzle 38 that is installed in the motor shell bottom, so that with cleaning fluid lead fan and motor shell inside.Conduit 36 is connected on the nozzle 38 and with the source of clean fluid (not shown) of carrying under pressure and links to each other.In addition, nozzle 32 can further be installed in the top 14 of motor shell 5.Sealing ring 34 or analog are used for preventing that any gas or grease from flowing out to the outside of motor shell in the zone of nozzle.Perhaps, as shown in Figure 5, nozzle 48 can pass the sidewall of bottom 16.In this case, nozzle 48 preferably places on the brace table 46 on the bottom of a bottom 16 that is connected to motor shell 5.By nozzle and conduit (not shown) are risen on the height of motor shell bottom, described brace table 46 guarantees that the grease and the liquid that are accumulated on the motor shell bottom can correctly be discharged.A control system makes the cleaning system to be activated by manual or automated manner.
In an alternate embodiment shown in Fig. 6 and 7, range hood 60 not as described above form of implementation assemble lower panel like that.As a kind of replacement, framework 62 comprises that an overall shape is rectangle and has perisporium 58 and the top panel 52 of the flange that stretches out from three sides.When framework 62 was connected on the outer cover 2, the size and the position of the opening in the top panel 52 made it install round motor shell.Be provided with a end wall 57 with cover part 54 towards the rear portion of panel.Cover part 54 is provided with the scupper hose of the sidewall that is used to pass bottom 76 and the additional space of any cleaning fluid distributor 48.This embodiment has increased the suction area of motor shell by the size/number that increases air intake 70.Yet it also can reduce the free space of range hood internal part (for example distribution and cleaning fluid delivery system).
In Fig. 8 and 9, expressed another alternate embodiment.Range hood 100 is equipped with the ambient air entrance system of previous embodiment.Yet except air intake 120, ambient air inlet framework panel 112 and lower panel 108, range hood 100 also has an air admission hole 140 that is located immediately under the fan 106.Air admission hole 140 is formed by the opening in motor shell bottom and the lower panel 108, and described opening aligns.The size that changes air admission hole 140 will change the suction force of air admission hole with respect to air intake 120.For example, the diameter that reduces air admission hole will reduce the air capacity by air admission hole 140 suctions, and increase the air capacity by air intake 120 suctions.The diameter that increases air admission hole 140 will play and above-mentioned reverse effect.For the sake of security, range hood 100 is provided with a fan grid 136.Grease cap 122 is connected on the fan grid 136, so that catch under any row and the following grease that drips on the grid.
Though those skilled in the art should be appreciated that preferred and alternate embodiment are had been described in detail, in the scope that does not exceed the principle of the invention, can carry out certain improvement.
