Description

Range hood{RANGE HOOD}

The present invention relates to a range hood that can be tightly fixed to the upper cabinet of a sink by pressing the main body frame.

The content described in this part simply provides background information on an embodiment of the present invention and does not constitute prior art.

Generally, range hoods are installed at a certain distance above heaters such as gas ranges, electric ranges, or oven ranges in the kitchen, and remove odors, smoke, gas, oil vapor, and fine dust generated during the process of cooking food through the heater. It is a device that sucks in polluted air and exhausts it outdoors.

Range hoods are installed in various forms such as island style hoods, chimney hoods, box style hoods, oven up hoods, slim style hoods, and dome hoods. You can select and use a range hood that suits your lifestyle and kitchen interior atmosphere.

Figure 1 is a diagram of a conventional conventional range hood installed in a kitchen.

Referring to FIG. 1, a general range hood 10 of the prior art has a main body frame 11 that has an outer shape and a hollow interior, and a corresponding position of an inlet 12a disposed on the lower side of the main body frame 11. A filter 12 that is disposed and detachably installed to filter out foreign substances, a lighting lamp 13 installed on one side of the inside of the main body frame 11, and a main body frame 11 located above the filter 12. A fan motor 14 that is mounted on the upper part of the interior and rotates when supplied with power, a fan 15 that is connected to the fan motor 14 and rotates to suck in odors, smoke, oil vapor, etc., and one end of the fan motor 14 An exhaust duct 16 is provided at one end to form an inlet and at the other end to form an outlet towards the outdoor side.

Here, the fan 15 connected to the fan motor 14 and disposed between the main body frame 11 and the exhaust duct 16 includes a centrifugal fan, an axial fan, etc. In addition, in individual houses, the exhaust duct 16 is installed exposed to the outdoors, and in multi-family houses such as apartments or townhouses, the exhaust duct 16 is installed through a ventilation duct (not shown) placed between households. It is installed.

In this range hood 10, when a cooking container such as a pot or frying pan containing food to be cooked is placed on the heater 20 such as a microwave or gas range and heated, odors, smoke, oil vapor, etc. are emitted during the cooking process of the food. This happens.

The user operates the range hood 10 to prevent odors, smoke, oil vapor, etc. generated during cooking from spreading into the indoor space. At this time, the fan 15 dissipates the odor, smoke, oil vapor, etc. as indicated by the arrow in FIG. 1. Foreign substances are filtered out through the filter 12 as they are sucked in by the suction force generated while rotating, and are soon discharged outdoors through the exhaust duct 16.

The user can set the wind speed to strong, medium, or weak to adjust the suction performance of the fan (15). However, as the wind speed of the fan (15) increases, the suction power improves, but the operating noise of the fan (15) may increase. There is a problem.

Currently, a height-variable range hood is provided that allows the height of the range hood to be adjusted up and down to increase suction power while reducing the operating noise of the fan (15). However, height-adjustable range hoods have problems such as securing space above and below to install devices for adjusting the height, and requiring installation manpower and technology.

In this way, the height-variable range hood, which allows the installation height of the range hood to be adjusted as a whole, blocks the user's view and makes cooking inconvenient when the hood is lowered to the target low point height, that is, to a position adjacent to the cooking vessel, when the user's height is above the standard adult height. can give you In this case, there is a problem in that the user has no choice but to lower the range hood to a height where the user's view can be secured, instead of lowering the range hood to the target low point height in consideration of the user's height.

In particular, a built-in range hood installed on the upper cabinet of the sink can be fixed to the side wall of the upper cabinet of the sink using a bolt fixing method using a bracket. This built-in range hood fixation method has the advantage of being easy to install and low material costs as it can be fixed to the upper cabinet with simple parts (brackets and bolts, etc.), but it is a built-in range hood with no space for heavy objects or bolts on the side. There is a problem that it is not suitable as a fixing method for the range hood.

The present invention is intended to solve the problems of the prior art described above. Instead of directly fixing the range hood to the wall using a fixing bracket, the present invention presses the range hood to the lower plate of the upper cabinet using a fixing unit. and a range hood that can be fixed in close contact with the range hood.

However, the technical problem to be achieved by the present invention is not limited to the technical problems described above, and other technical problems may exist.

As a technical means for achieving the above-described technical problem, a range hood includes: a main body frame; And a fixing unit disposed adjacent to the lower side of the main body frame to fix the main body frame to the lower fixing target plate in a pressed state, wherein the fixing unit includes a hood bracket, a rotating bracket, and a fixture. and when the fixture is fastened to the hood bracket, the pivoting bracket presses the fixing target plate so that the main body frame is fixed to the fixing target plate.

Alternatively, the hood bracket may include a protrusion protruding from the outer surface of the main body frame to form a predetermined spaced apart space; and a fixture penetrating portion extending from the protrusion toward the inner side of the main body frame.

Alternatively, the fixture is fastened to the fixture penetrating portion, so that when rotated in a first rotation direction, the rotation bracket rotates in a direction in which the pressure pressing the fixing target plate becomes stronger, and is rotated in a direction opposite to the first direction. When rotating in the second rotation direction, the rotation bracket is rotated in a direction in which the pressure pressing the fixing target plate is weakened.

Alternatively, the pivoting bracket may include a pivoting fixing portion that presses the lower fixing target plate in the space formed by the protrusion; and a pressing portion extending from the pivoting fixture toward the inner side of the main body frame and being pressed by a fixture passing through the fixture penetrating portion.

Alternatively, the fixture is fastened to the fixture penetrating portion and presses the pressing portion when rotating in a first rotation direction so that the rotation fixture rotates in a direction in which the pressure pressing the fixing object plate becomes stronger, and the first rotational direction When rotating in the second rotation direction, which is opposite to the direction, the pressure applied to the pressing portion is lowered so that the rotating fixing portion rotates in a direction in which the pressure pressing the fixing target plate is weakened.

Alternatively, the rotating fixing part has a lower surface formed with a curved lower inclined surface, and the lower inclined surface is curved to have a preset curvature based on a contact point in contact with the fixing target plate.

According to the problem-solving means of the present invention described above, the present invention does not use a method of directly fixing the range hood to the wall using a fixing bracket, but presses and secures the range hood to the lower plate of the upper cabinet using a fixing unit. There is no need to use various parts such as fixing brackets, fastening means, tools, etc., and it is effective in fixing it in close contact without a gap between the lower plate of the upper cabinet and the range hood in a simple way.

The main body frame 110 has an inner frame 111 disposed in the internal space. The inner frame 111 is located adjacent to the rear of the main body frame 110, and the rail portion ( 131) is deployed. The fan motor unit unit 160 disposed on the inner upper side of the main body frame 110 is located between the inner frame 111 and the front frame 112.

The bottom frame 113 formed on the bottom of the main body frame 110 has an opening hole corresponding to the position and size of the suction part 120 so that the suction part 120 moves up and down. This lower frame 113 may be formed of the same material as the main body frame 110, but since it is located on the upper part of the heater 20, it is formed of a material resistant to heat, moisture, shock, and contamination and is coupled to the main body frame 110. It can be. Additionally, the lower surface frame 113 may be the same as the lower surface of the sink upper cabinet. In other words, the lower plate of the sink upper cabinet can be used as the lower frame 113 of the range hood of the present invention.

Meanwhile, a limit switch (not shown) is installed inside the main body frame 110 to control the operation of the fan motor unit 160 by detecting entry and exit by the touch of the slider 132. When the slider 132 is moved to the lower part of the main body frame 110, the limit switch detects this and the fan motor unit 160 can be automatically operated.

In addition, the front frame 112 located in front of the main body frame 110 is equipped with a control unit 115 including several switches at the bottom, and the control unit 115 has a wind volume control function that can adjust the intensity of the wind volume in multiple stages. It includes a switch, a lighting switch that turns on/off a lighting lamp built into the main body frame 110, etc.

At least one through hole (not shown) may be formed on the upper surface of the main body frame 110.

A cover frame 116 is disposed on the upper surface of one through-hole, and the fan motor unit unit 160 and the exhaust duct 170 are disposed in communication with the other through-hole.

At this time, as shown in FIG. 3, the cover frame 116 is formed to have an internal space larger than the size of the motor unit so that the motor unit of the drive unit 140 can be placed in the internal space. This cover frame 116 has a motor part disposed on the cover frame 116 disposed at the upper end of the through hole with respect to the through hole, and the remaining driving parts excluding the motor portion are located in the inner space of the main body frame 110 disposed at the lower end of the through hole ( 140) components may be arranged.

The suction unit 120 includes a side frame 121 including a slider 132, and a filter frame 122 disposed in the center of the side frame 121 to allow the filter 125 to be mounted or detached on the front. Includes. The filter 125 may be made of a network with a large number of fine holes, and polluted air such as odor, smoke, or oil vapor is sucked in through the intake port due to the suction force generated as the fan motor unit unit 160 rotates. Foreign substances are filtered out through the filter 125 and are soon exhausted to the outdoors through the exhaust duct 170. At this time, the filter 125 is made of aluminum, which is light, hygienic, and resistant to corrosion, and is preferably made of triple aluminum.

The rail portion 131 is disposed on the outer side of the inner frame 111 disposed in the inner space of the main body frame 110, and the slider 132 is disposed on the inside of the suction portion 120 and is attached to the rail portion 131. It is guided by a sliding movement. The slider 132 is coupled to the rail portion 131 so as to be movable up and down, allowing the suction portion 120 to be stored in or pulled out from the main body frame 110.

The driving unit 140 is an actuator disposed inside the cover frame 116 disposed adjacent to the upper surface of the main body frame 110, and allows the suction unit 120 to be drawn in or out of the inner frame 111 in the vertical direction. Provides driving force that can

This driving unit 140 may be fixed to the main body frame 110 or the inner frame 111 by a fixing bracket 150. The fixing bracket 150 is divided into a support 151 and a case 152, the support 1511 is disposed in the inner space of the main body frame 110, and the case 152 has a suction part to correspond to the support 51. It is placed on (120).

The upper end of the support 151 may be coupled to the inner frame 111 by a fixing means 155. The support 151 extends directly downward, and a sliding bar is disposed inside, and the lower end of the support 151 is coupled to the lower end of the case 152.

This range hood can be installed by being built into and fixed to the upper cabinet of the sink (built-in hood).

Figure 4 is a view of a range hood according to an embodiment of the present invention viewed from the inner side direction of the main body frame, and Figure 5 is a view of the range hood according to an embodiment of the present invention viewed from the outer side direction of the main body frame; Figure 6 is a view of the range hood according to an embodiment of the present invention as seen from the front direction of the main body frame.

4 to 6, the range hood is disposed adjacent to the lower side of the main body frame 110, and the main body frame 110 is pressed against the fixing target plate, that is, the lower plate 30 of the upper cabinet. It includes a fixing unit 200 that is fixed to the lower plate 30.

In the fixing unit 200, a hood bracket 210 and a pivoting bracket 220 are coupled using a fixture 215, and the lower portion of the pivoting bracket 220 rotates in a certain direction based on the fixture 215. The lower plate 30 and the rotating bracket 220 may be fixed in a pressed state.

The hood bracket 210 is disposed at a position corresponding to the opening hole formed in the lower side of the main body frame 110, and is formed to protrude from the outer surface of the main body frame 110 to form a predetermined space. That is, the hood bracket 210 has a protrusion 211 protruding from the outer surface of the main body frame 110 to form a preset space, and a fixture extending from the protrusion 211 toward the inner side of the main body frame 110. Includes part 212. A fastening hole 211a is formed in the fixture penetrating portion 212 to allow the fixture 215 to penetrate therethrough.

The rotation bracket 220 is disposed in a spaced space, the upper end is fixed to the hood bracket 210 through the fixture 215, and the lower end has a preset rotation angle with respect to the hood bracket 210 around the fixture 215. It is rotated as much as it comes into contact with the lower plate 30 of the upper cabinet. The lower surface of this rotating bracket 220 protrudes downward from the front to the rear of the upper cabinet.

That is, the rotating bracket 220 is connected to the main body from the rotating fixing part 221 that presses the lower fixing target plate, that is, the lower plate 30 of the upper cabinet, in the space formed by the protrusion 211, and the rotating fixing part 221. It extends toward the inner side of the frame 110 and includes a pressing portion 222 that is pressed by the fixture 215 passing through the fixture penetrating portion 212.

The pressing portion 222 is formed to be inclined diagonally downward so that it can be rotated by a certain rotation angle within the space. As the fixture 215 rotates in the first rotation direction, the pressing portion 222 pushes one surface corresponding to one end of the fixture 215 so that the rotating fixture 221 can press the fixing target plate.

The rotating fixing part 221 may have a lower surface formed in a curved lower slope. At this time, the lower slope may be curved to have a predetermined curvature based on the curved point, and the radius of curvature and the curved point may be arbitrarily determined. At this time, the lower inclined surface of the rotating fixing part 221 has a curved point formed adjacent to the rear of the upper cabinet, and may form a protruding curved surface that is convex downward toward the lower plate 30 of the upper cabinet based on the curved point. For example, the lower slope may form a curved surface that slopes downward from the front to the back of the upper cabinet, and then form a curved surface that slopes upward again based on the curved point.

Therefore, as the thickness of the lower plate of the upper cabinet becomes thinner, the pivot bracket 220 forms a contact point with the lower plate 30 of the upper cabinet near the curved point of the lower slope, and as the thickness of the lower plate of the upper cabinet becomes thicker, the pivot bracket 220 forms a contact point with the lower panel of the upper cabinet 30 near the curved point of the lower slope. A contact point is formed. That is, contact may be formed close to the rear of the main body frame 110.

The fixture 215 is fastened to the fastening hole 211a of the fixture penetration portion 212 in a horizontal direction with respect to the lower plate 30 of the upper cabinet. When this fixture 215 rotates in the first rotation direction, it presses the pressing part 222 so that the rotation fixing part 221 rotates in the direction in which the pressure pressing the fixing target plate becomes stronger, and in the first rotation direction (ex. When rotating in the second rotation direction (ex. clockwise), which is opposite to the counterclockwise direction, the pressure applied to the pressing part 222 is lowered, so that the pressure with which the rotating fixing part 221 presses the fixing target plate is about Turn in the direction of sunset.

This fixing unit 200 is configured to operate the rotating fixing part 221 of the rotating bracket 220 by the rotational action of tightening/loosening the fixture 215 even if the thickness of the lower plate 30 of the upper cabinet where the range hood 100 is installed is different. ) adjusts the pressure applied to the lower plate 30 of the upper cabinet so that the main body frame 110 is fixed to the lower plate of the upper cabinet while the rotating bracket 220 presses the lower plate of the upper cabinet.

As shown in FIG. 6, the separation space (w1) between the hood bracket 210 and the outer surface of the main body frame 110 and the rotation section (h1) of the rotation bracket 220 according to the thickness of the lower plate 30 of the sink lower cabinet. By being limited and fixed to the upper surface of the lower frame 113, it is possible to obtain the effect of supporting the force applied to the lower plate 30 of the upper cabinet by the frame 113.

For example, with the front frame 112 separated from the main body frame 110, the range hood 100 is placed in the upper cabinet, and then the fixing unit 200 is assembled into the opening holes formed in the lower portions of both sides of the main body frame 110. After fixing the upper cabinet lower plate 30 and the bottom surface of the main body frame 110, the fixture 215 is rotated in the first rotation direction to prevent a gap from forming, and the pressurizing part 222 is pressed and rotated. The pressure with which the fixing part 221 presses the lower plate of the upper cabinet becomes stronger, and as a result, the rotating fixing part 221 contacts the lower plate 30 of the upper cabinet in a pressed state, so that the main body frame 110 is in close contact with the lower plate of the upper cabinet. Make sure it is fixed.

In addition, the fixing unit 200 of the present invention allows the range hood 100 and the lower plate 30 of the upper cabinet to be damaged due to distortion or sagging of the range hood after a long period of time has elapsed with the range hood 100 installed on the upper cabinet of the sink. When a gap occurs between the fixtures, the fixture 215 is appropriately rotated in the first rotational direction (for example, clockwise) so that the pressure with which the rotating fixture 221 presses the lower plate of the upper cabinet becomes stronger. The main body frame 110 can be more firmly fixed to the lower plate 30.

As such, the present invention can be applied to all range hoods installed in a built-in manner, and in particular, when applied to the range hood shown in FIG. 3, the suction part 120 can be inserted or withdrawn in the vertical direction with respect to the main body frame 110. ) By arranging the rail part 131 and the slider 132 inside the suction part 120, the overall width of the suction part 120 can be made wide.

In addition, the present invention allows the suction unit 120, which sucks in polluted air, to be disposed at the rear of the heater, so that polluted air such as water vapor, oil vapor, and food odor generated during cooking is sucked in and discharged from the rear of the heater. You can.

Therefore, the present invention prevents the contaminated air from escaping into the indoor space located in the front of the heater by sucking the contaminated air generated during cooking toward the rear of the heater, thereby preventing the space around the heater from cooking or You can maintain comfortable air conditions even after cooking is complete. In particular, the present invention arranges the rail part 131 and the slider 132 inside the side frame 121 of the main body frame 110 and the suction part 120, respectively, so that the main body frame 121 and the suction part 120 ), the suction power can be further improved by reducing the spacing between the side frames 121.

The description of the present invention described above is for illustrative purposes, and those skilled in the art will understand that the present invention can be easily modified into other specific forms without changing the technical idea or essential features of the present invention. will be. Therefore, the embodiments described above should be understood in all respects as illustrative and not restrictive. For example, each component described as unitary may be implemented in a distributed manner, and similarly, components described as distributed may also be implemented in a combined form.
