Description

Variable hood device for kitchen

The present invention relates to a hood device installed in a kitchen, and more particularly, to a variable hood device for a kitchen, which can be adjusted in position, and can perform more efficient exhaust by approaching a odor or gas generating point. .

Noxious gases such as odors, fine dust, carbon monoxide, and carbon dioxide generated when food is heated and cooked in the kitchen are pollutants that contaminate indoor air, and may be unhealthy and unpleasant for indoor residents. Accordingly, it is necessary to ventilate the room frequently, but in practice, ventilation is often insufficient.

On the other hand, the kitchen hood, as a ventilation device for discharging harmful gases as well as smoke or smell generated during the cooking process to the outside, is installed above a heating source such as a gas stove or an induction stove. Such a hood is, for example, a device including a casing for receiving gas, an intake fan, a filter, a duct, and the like, and has a structure for driving the intake fan to suck up gas, and exhausting the sucked up gas through the duct.

However, the conventional hood has a disadvantage in that the distance from the heating source is long, so that the gas cannot be efficiently sucked up. In other words, it is not possible to completely remove the harmful gas generated from the gas stove or the smell generated from the frying pan. However, if the intake fan is rotated at a high speed, the gas removal rate increases, but this time there is a problem of mechanical noise.

In order to solve this problem, Korean Patent Application Laid-Open No. 10-2009-0081262 (a kitchen hood) has been disclosed. The disclosed kitchen hood includes: a main cover installed on one side of a sink to be positioned above a gas range, a control unit provided on one side of a lower front side, and an exhaust port formed on one side of the upper surface; an auxiliary cover installed on the other side of the upper surface of the main cover so as to communicate with the upper surface of the main cover; an exhaust fan installed in the exhaust port formed on one side of the upper surface of the main cover and connected to the control unit; The lower end is connected to the other side of the lower end of the main cover, the upper end is connected to the upper end of the auxiliary cover, the up and down moving means connected to the control unit and the up and down moving means are connected to both sides, and the up and down moving means connected to the control unit is operated. It is composed of an intake means that ascends and descends accordingly.

However, the disclosed kitchen hood has a limitation in that the intake means moves only in the vertical direction. For example, since the intake means cannot move in the horizontal direction, it is difficult to use in a kitchen in which a plurality of heating sources are installed.

In addition, since the fan rotating motor is disposed at the lower end of the intake means, noise is high during use, and in particular, as the motor is located close to the heating source, it has a disadvantage that it is heated together with the food by the heating source.

Hereinafter, one embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

1 is a view showing a configuration and application example of a variable hood for kitchen device 30 according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view separately illustrating the variable hood device for kitchen shown in FIG. 1 . . In addition, FIG. 3 is a view showing the hood 40 and the exhaust pipe 65 of FIG. 1 . In addition, FIGS. 4A to 4C are partial cross-sectional views illustrating various exhaust methods applicable to the variable hood device for kitchen according to an embodiment of the present invention.

As shown, the variable hood device 30 according to the present embodiment includes a bent column 31 , a support body 33 , a first horizontal bar 34 , a slider 36 , and a second horizontal bar 38 . ), a folding hood 40, an exhaust pipe 65, and an exhaust means.

The bending column 31 is formed by pressing a rectangular metal plate having a predetermined thickness and width, and is fixed to the wall surface 11a of the kitchen 11 and is perpendicular to the top plate of the sink 12 . The bending column 31 can be installed anywhere on the top plate of the sink 12 , but it is better to arrange it as close to the gas stove 13 as possible.

The bent column is formed by bending a stainless steel plate and has a plurality of locking holes 31a. The locking hole 31a is a part on which a locking bracket 33c to be described later is hooked and supported, and is vertically spaced apart from each other. The distance between the engaging holes 31a can be designed in various ways. In addition, as long as the locking bracket 33c can be hung and fixed, the number or type of the locking hole 31a can be varied. The fixing of the bent column 31 to the wall surface 11a can be implemented with an adhesive tape (not shown). The bending column can also be made of synthetic resin instead of metal.

In addition, the support body 33 is a member for supporting the first horizontal bar 34 in a state in which it is detachably draped over the locking hole 31a of the bent column 31 . It is determined by the user which of the plurality of locking holes (31a) to support the support body (33) to which locking hole (31a).

This support body 33 is composed of a body body (33a) and a locking bracket (33c). The body body 33a takes the shape of a hexahedron and has a support hole 33e in the central portion. The support hole 33e is a through hole having a predetermined inner diameter and extends vertically. That is, the central axis of the support hole 33e is perpendicular to the top plate of the sink.

The locking bracket (33c) is a bent piece in the shape of an approximately L fixed to one side of the body body (33a). When the locking bracket 33c is inserted into the locking hole 31a in the horizontal direction and released, the locking bracket 33c descends by the action of gravity and is automatically caught and supported by the locking hole 31a. As a result, the support body 33 is mounted and fixed to the bending column 31 through the locking bracket 33c and the locking hole 31a.

The first horizontal bar 34 is a bar-shaped member supported by the support body 33 and extending in a straight line in the horizontal direction, and supports the slider 36 to be slidably movable. A rotation shaft 34c is fixed to a lower side of one end of the first horizontal bar 34 .

The rotating shaft 34c is a shaft member of a certain diameter inserted into the support hole 33e. The rotating shaft 34c rotates in a state in which it faces the inner circumferential surface of the support hole 33e. As the rotation shaft 34c is inserted into the support hole 33e, the first horizontal bar 34 automatically maintains a horizontal level, and it is possible to rotate in the left and right directions around the rotation shaft 34c. Insertion and separation of the rotation shaft 34c with respect to the support hole 33e is free.

In addition, an extension slit 34a is formed in the first horizontal bar 34 . The extension slit 34a is a slit of a predetermined width extending in the longitudinal direction of the first horizontal bar 34 and supports the slider 36 to be movable in a straight line. The slider 36 itself is supported by the first horizontal bar 34 and moves linearly while maintaining a constant altitude.

The slider 36 has a travel guide 36c, a cover plate 36a, and a support pin 36e. The traveling guide 36c is a part that moves along the longitudinal direction of the extension slit while being inserted into the extension slit 34a, and both sides face the inward surface of the extension slit 34a. Due to the action of the travel guide 36c, the slider 36 does not twist or turn left and right while driving.

The cover plate (36a) is a plate-shaped member integrally formed with the upper side of the traveling guider (36c), spans the upper surface of the first horizontal bar and prevents the traveling guider (36c) from falling into the lower part of the first horizontal bar (34). . The support pin 36e is a shaft vertically fixed to the upper center of the cover plate 36a, and is fitted into the pin receiving hole 38a of the second horizontal bar 38 . The slider 36 having the above configuration is freely separable from the first horizontal bar 34 . For example, the user may replace the slider 36 .

The second horizontal bar 38 is a bar-shaped member extending in a straight line, and has a pin receiving hole 38a at one end thereof. The support pin 36e of the slider is accommodated in the pin receiving hole 38a. The second horizontal bar 38 can rotate left and right based on the support pin 36e. As a result, the second horizontal bar 38 is supported by the slider 36 and is capable of linear motion and rotational motion while maintaining the level.

The support body 33, the first horizontal bar 34, the slider 36, and the second horizontal bar 38 having the above configuration are not fixed with bolts or the like, but only operate in a fitted state. It can be easily disassembled accordingly. It is possible to replace some components, or to remove all components, clean them, and then reassemble them.

On the other hand, the folding hood 40, as being mounted on the extended end of the second horizontal bar 38, can be unfolded only when in use, and folded when not in use. That is, when cooking, it is arranged on the upper portion of the gas stove 13 in an unfolded state, and is folded when not needed. The basic function of the folding hood 40 is the same as that of a general hood. In other words, it absorbs odors or gases generated during cooking and exhausts them. A description of the folding hood 40 will be described later.

The exhaust pipe 65 is a bendable corrugated pipe extending in the longitudinal direction, and one end is connected to the head part 41 of the folding hood 40 , and the other end is coupled to the fixing block 66 .

The fixing block 66 has a substantially hexahedral shape and is fixed in a state sandwiched between the window frame 15a and the casement window 15b, as shown in FIG. 1 . Reference numeral 17 in FIG. 1 denotes a support block supporting the fixing block 66 . Since the exhaust pipe 65 is fixed to the window 15 , the gas collected by the folding hood 40 can be exhausted to the outside through the exhaust pipe 65 .

In addition, the exhaust means is to induce a negative pressure in the folding hood (40) by forming an air flow in the direction toward the outside in the exhaust pipe (65). That is, by causing a negative pressure to be formed inside the head portion 41 of the folding hood 40, harmful gases or odors generated during cooking, that is, the exhaust target gas, are guided to the exhaust pipe 65 through the head portion 41. will be.

The exhaust means includes a blower 67 and an air guide pipe (67a). The blower 67 is installed outside the exhaust pipe 65 . For example, it may be disposed on the shelf 16 installed in the kitchen. The position of the blower 67 can be changed as long as it can supply air to the inside of the exhaust pipe 65 . The blower 67 generates compressed air and supplies it into the air induction pipe 67a.

The air guide pipe (67a) blows the air supplied from the blower (67) into the exhaust pipe (65). An injection nozzle 67b is mounted at an end of the air guide pipe 67a. The air ejected through the injection nozzle 67b moves to the downstream side of the exhaust pipe 65 and then exits to the atmosphere. At this time, the upstream pressure is lowered, and of course, the exhaust gas flows into the exhaust pipe 65 .

The exhaust means shown in FIG. 4A includes the venturi part 65c, and the air guide pipe 67a is introduced into the inner space of the venturi part 65c and then bent downstream. As the air is ejected through the air guide pipe 67a, the internal pressure of the venturi unit 65c is lowered, so that the exhaust gas is more efficiently exhausted.

The air guide pipe 67a of FIG. 4b takes a shape bent downstream after being drawn into the exhaust pipe 65 .

In addition, the exhaust means of Figure 4c is provided with a stream guider (65e). The stream guider 65e narrows the flow cross-sectional area of the exhaust pipe 65 so that the exhaust gas is discharged at a higher speed. In addition, a plurality of air guide tubes (67a) are symmetrically disposed on the downstream side of the stream guider (65e).

5 and 6 are views for explaining the configuration and operation of the folding hood 40 applicable to the variable hood device 30 for the kitchen according to an embodiment of the present invention. 5 is a state in which the folding hood 40 is unfolded, and FIG. 6 is a state in which it is folded.

As shown, the folding hood 40 includes a head portion 41 taking the shape of a hollow cylinder, and a wing portion 43 installed under the head portion. The head part 41 is supported by the extended end of the second horizontal bar 38 and is connected to the exhaust pipe 65 . As the negative pressure is formed inside the exhaust pipe 65 , the gas under the head part 41 is collected in the head part 41 and then sucked into the exhaust pipe 65 . The head part 41 and the exhaust pipe 65 are separable.

In addition, a plurality of lower fixing hinges 41e are fixed to the lower portion of the head portion 41 . The lower fixed hinge 41e corresponds to the rotation hinge 43e of the split blade 43a one-to-one. By connecting the hinge pins 43f in a state in which each of the lower fixed hinges 41e and the rotary hinges 43e are brought into contact, the split wings 43a for the head portion 41 are coupled.

The wing portion 43 includes a plurality of split blades (43a). The split wings 43a all have the same size, and as described above, they are connected to the lower fixed hinge 41e by a hinge pin 43f. Each split blade (43a) maintains the deployed state in contact with the thickness surface of the neighboring split blade (43a) in the state fully deployed upwards. To this end, a protrusion 43c is formed on one side of each of the split blades 43a, and a groove portion 43d is formed on the opposite side of the thickness surface.

The protruding portion 43c of each split blade 43a is fitted into the groove portion 43d of the adjacent split blade 43a in a state in which the blade portion 43 is fully opened. As described above, by inserting the groove portion 43d into the protrusion portion 43c, the split blade 43a can be maintained in close contact with each other without shifting with respect to each other while receiving the action of gravity.

In order to fold the wing portion 43, if any two split blades 43a are held by hand and displaced, the other split blades 43a are also separated and swept downward by the action of gravity, resulting in the state of FIG. 6 .

The wing portion 43 may be made of translucent heat-resistant glass, acrylic, or the like. Alternatively, as shown in FIG. 5 , the edge part may be made of stainless steel and the light transmitting window 43b may be fixed to the inside. By using the light-transmitting member as described above, even if the foldable hood 40 is lowered as far as possible to the height just above the cooking vessel, the lower condition of the foldable hood can be visually confirmed.

7 and 8 are diagrams for explaining the configuration and operation of another type of folding hood applicable to the variable hood device for the kitchen according to an embodiment of the present invention.

Hereinafter, the same reference numerals as the above reference numerals refer to the same members having the same functions.

The folding hood 40 shown in FIG. 7 includes a head portion 41 , a fixed rib 45a , a rotating rib 45c , a rib fixing and fixing means, and a heat-resistant light transmitting fabric 51 .

The fixing rib 45a is a member fixed to the periphery of the head part 41 and extending in a radial direction around the head part and forming a predetermined interval, and has a receiving groove 45b. The receiving groove 45b is a groove for receiving the insertion portion 45d of the rotary rib 45c.

The rotary rib 45c is connected to the fixed rib 45a through a connecting pin 45q, and is a linear member that can rotate up and down like an umbrella. An insertion portion 45d is formed at an end of the rotary rib 45c. The insertion portion (45d) is a portion to be inserted into the receiving groove (45b). With the insertion part 45d inserted in the receiving groove 45b, the rotation rib 45c is connected to the fixed rib 45a by passing the connecting pin 45q.

The heat-resistant and light-transmitting fabric 51 is a known flexible heat-resistant flame-retardant fabric that is adhesively fixed to the bottom surfaces of the fixed ribs 45a and the rotating ribs 45c. The heat-resistant translucent fabric 51, like the waterproof fabric of an umbrella, is stretched when the rotating rib 45c is spread, and guides the gas to be exhausted from the lower part to the head.

On the other hand, the rib fixing means serves to maintain the unfolded state in the state in which the rotary rib 45c rotates upward. The rib fixing means includes a locking pin 45f and a spring 45m, as shown in FIG. 8 . In addition, a locking groove 45e is formed on one side of the insertion portion 45d so that the rib fixing means can operate, and a mounting space portion 45p is provided in the fixing rib 45a.

The locking groove 45e is a groove into which the end of the locking pin 45f is inserted, and the mounting space 45p is a space in which the spring 45m and a part of the locking pin 45f are accommodated. The mounting space 45p corresponds to the locking groove 45e.

The locking pin 45f is a pin-shaped member movable in the direction of arrow c or the opposite direction, and has a pin head 45g and a spring locking portion 45h. The pin head 45g is, for example, a handle that the user grabs to pull the locking pin 45f in the direction of the arrow c.

In addition, the spring engaging portion (45h) is a portion that receives the elastic force by the spring (45m). The locking pin 45f is elastically supported in the direction opposite to the direction of the arrow c by receiving the elasticity of the spring through the spring engaging portion 45h, and is inserted into the locking groove 45e to maintain the state in which the rotation rib 45c is unfolded. .

In order to fold the rotary rib 45c, the locking pin 45f is separated from the locking groove 45e by pulling the pin head 45g protruding from the side of the fixed rib 45a in the direction of the arrow c. When the locking pin 45f is separated, the rotary rib 45c is folded downward by its own weight.

In order to unfold the folded rotary rib 45c, in a state in which the locking pin 45f is pulled in the direction of the arrow c, the rotary rib 45c is raised upward so that the locking groove 45e is located on the extension line of the locking pin 45f. After doing so, release the locking pin 45f. When the locking pin 45f is released, the locking pin 45f is fitted into the locking groove 45e by the action of the spring 45m.

9 and 10 are views for explaining another configuration of a folding hood applicable to the variable hood device for the kitchen according to an embodiment of the present invention.

The folding hood 40 shown in FIG. 9 includes a head portion 41, four fixed ribs 45a spaced at regular intervals, and a rotating rib 45c linked to each fixed rib 45a by a connecting pin 45q. , a heat-resistant translucent fabric 51, and a rib fixing means.

The rib fixing means rotates upwardly and maintains the unfolded state, and has an arc-shaped rod 46 , a ratchet finger 46a , a locking tube 47 , and a tube holder 48 .

The arc-shaped rod 46 is an arc-shaped member of a certain curvature, and one end is integrally formed with the rotary rib 45c, and the other end is inserted into the side hole 41f. The side hole 41f is a through hole formed in the periphery of the head portion 41, and allows the arc-shaped rod 46 to pass therethrough. The arc-shaped rod 46 is partially inserted into the head portion 41 through the side hole 41f.

In addition, a ratchet finger (46a) is installed on the arc-shaped rod (46). The ratchet finger 46a is a member rotatably installed on the arc-shaped rod 46 through the finger shaft 46c, and prevents the rotary rib from descending by being caught by the toothed portion 47c to be described later.

The locking tube 47 is a square pipe-shaped member fixed to the outer portion of the head portion 41 through the tube holder 48 and has a toothed portion 47c on the inner side. The toothed portion 47c is a portion caught by the ratchet finger. The arc-shaped rod 46 is inserted into the passage 47a provided by the locking tube 47, and can be freely moved in the direction of the arrow g or the opposite direction according to the rotation of the rotary rib 45c (if there is no ratchet finger). do.

However, since the ratchet finger 46a is provided and a toothed portion is formed inside the locking tube 47, the arrow g-direction movement of the arc-shaped rod 46 is restricted. In other words, the once unfolded rotation rib 45c can maintain an unfolded state.

As mentioned above, although the present invention has been described in detail through specific embodiments, the present invention is not limited to the above embodiments, and various modifications are possible by those of ordinary skill within the scope of the technical spirit of the present invention.
