Description
- The present invention relates to a kitchen range hood and, more particularly, to an intake controlling device of a kitchen range hood.
- In general, a kitchen range hood is installed at an upper side of a kitchen range, such as a gas range, an oven range, or the like, in order to exhaust heat, various kinds of smells, steam and gases such as CO2 or the like generated according to imperfect combustion. The kitchen range hood exhausts a gas or contaminated air and prevents a bad smell. The features of the preamble of
claim 1 are known fromJP-A-401210742 -
Figure 1 is a side view showing a kitchen range hood installed at an upper side of a kitchen range in accordance with a conventional art. -
Figure 2 is an enlarged perspective view of the kitchen range hood in accordance with the conventional art. - As shown in
Figure 2 , a conventionalkitchen range hood 10 includes anexhaust duct 11; ablower 12 installed in theexhaust duct 11 and including a fan motor (not shown) and an exhaust fan (not shown); ahood cover 15 connected with theexhaust duct 11; and afilter 13 installed in thehood cover 15 and filtering a smell, dust or oil in the air sucked through theintake 14 of thehood cover 15. - The
kitchen range hood 10 is installed spaced apart with a certain interval at an upper side of thekitchen range 20. Theexhaust duct 11 discharges externally air sucked through theintake 14. - However, as for the conventional
kitchen range hood 10, because the entire region of theintake 14 is formed smaller than a cooking region of thekitchen range 20, it fails to discharge externally heat and contaminated air generated during a cooking process entirely. - For example, the conventional
kitchen range hood 10 cannot discharge externally the whole of heat and contaminated air generated when cooking by using a front gas burner of thekitchen range 20, so a portion of the heat and contaminated air spreads toward a user positioned in front of thekitchen range hood 10, making the user feel uncomfortable. - In addition, since the portion of the heat and contaminated air, that has not been discharged externally, remains indoors, the indoor environment is not maintained agreeably.
- Therefore, an object of the present invention is to provide an intake controlling device of a kitchen range hood capable of effectively discharging heat and contaminated air effectively through a kitchen range hood and thus maintaining an agreeable indoor environment.
- To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, there is provided an intake controlling device of a kitchen range hood as defined in
claim 1. - The foregoing and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings.,

Figures 3 to 8 . -
Figure 3 is a side view showing the construction of the kitchen range hood in accordance with the present invention. - With reference to
Figure 3 , thekitchen range hood 10 includes anexhaust duct 11; ablower 12 installed inside theexhaust duct 11 and including the fan motor (not shown) and an exhaust fan (not shown); ahood cover 15 connected with theexhaust duct 11; afilter 13 installed in thehood cover 15 and filtering a small and oil in the air sucked through anintake 14 of thehood cover 15; and an intake controllingdevice 100 installed at thehood cover 15 and selectively blocking opening regions of theintake 14. - The intake controlling
device 100 in accordance with the first embodiment of the present invention will now be described with reference toFigure 4 . -
Figure 4 shows a detailed construction of an intake controlling device of a kitchen range hood in accordance with a first embodiment of the present invention. - As shown in
Figure 4 , the intake controllingdevice 100 includes aninterception plate 102 installed at thehood cover 15 and selectively blocking a specific region (e.g., one of a first opening region, a second region and a central region) of theintake 14; amotor driving unit 103 for generating a motor drive signal for moving theinterception plate 102 to the specific region of theintake 14 according to user's selection; and amotor 101 for moving theinterception plate 102 to a specific region of theintake 14 according to the motor drive signal in order to block the specific region of theintake 14. - By blocking the first or second opening region of the
intake 14, an uptake rate of the opening region is increased. For example, when the first opening region of theintake 14 installed at an upper side of thefront gas burner 21 is opened and the second opening region of theintake 14 installed at an upper side of aback gas burner 22 is blocked, air is sucked only through the first opening region, making the uptake rate of the kitchen range hood is increased. Thus, because heat and contaminated air generated when cooking by using a gas burner (e.g., the front gas burner) of thekitchen range 20 can be discharged only through the first opening region of the kitchen range hood, the indoor environment can be agreeably maintained. - Meanwhile, when the second opening region of the
intake 14 installed at the upper side of theback gas burner 22 is opened and the first opening region of theintake 14 installed at the upper side of thefront gas burner 21 is blocked, air is sucked only through the second opening region, so the uptake rate of the kitchen range hood is increased. Accordingly, heat and contaminated air generated when cooking by using the gas burner 22 (e.g., back gas burner) of thekitchen range 20 are discharged only through the second opening region of the kitchen range hood and thus, the indoor environment can be agreeably maintained. - The central region is an in-between region of the first and second opening regions.
- Moving the
interception plate 102 to a specific region (e.g., one of the first and second regions and the central region) can be implemented in a variable manner according to user's selection. - An embodiment of the driving unit will be described with reference to
Figure 5 . -
Figure 5 is a circuit diagram showing a detailed construction of a driving unit of the intake controlling device in accordance with the first embodiment of the present invention. - As shown in
Figure 5 , themotor driving unit 103 includes: a user switch (US) for generating a switching signal for moving theinterception plate 102 to a specific region (one of the first and second opening regions and the central region) of theintake 14; a front limit switch (SF) for receiving the switching signal of the US, and cutting off power supply to themotor 101 when theinterception plate 102 is sensed, in order to move theinterception plate 102 to the first opening region of theintake 14; a center limit switch (SC) for receiving the switching signal of the US, and cutting off power supply to themotor 101 when theinterception plate 102 is sensed, in order to move theinterception plate 102 to the central opening region of theintake 14; and a back limit switch (SB) for receiving the switching signal of the US, and cutting off power supply to themotor 101 when theinterception plate 102 is sensed, in order to move theinterception plate 102 to the second opening region of theintake 14. - The
motor 101 is driven when the US and the SF are simultaneously turned on, when the US and the SC are simultaneously turned on, or when the US and the SB are simultaneously turned on. - The intake controlling device of the kitchen range hood in accordance with the first embodiment of the present invention will now be described with reference to
Figures 3 to 5 . , - First, when the US is selected by a user, the
motor driving unit 103 moves theinterception plate 102 to a specific region of theintake 14 by controlling themotor 101. In this case, the position of theinterception plate 102 is determined by the user. - For example, when a terminal 'F' of the US is selected in order to block the first opening region of the
intake 14, power is applied to themotor 101 through the front limit switch (SF) electrically connected with the terminal 'F' of the user switch (US), and themotor 101 is driven by power and moves theinterception plate 102 to the first opening region. When theinterception plate 102 comes in contact with the front limit switch SF, the SF cuts off power supply to themotor 101. Namely, when the SF contacts with theinterception plate 102, the SF is turned off to cut off power applied to themotor 101, and accordingly, theinterception plate 102 is stopped at the first opening region of theintake 14 to block it. - When the user selects a terminal 'C' of the user switch in order to block the central region of the
intake 14, power is applied to themotor 101 through the center limit switch (SC) electrically connected with the terminal 'C' and themotor 101 is driven by power and moves theinterception plate 102 to the central region. At this time, when theinterception plate 102 comes in contact with the center limit switch SC, the SC cuts off power supply to themotor 101. Namely, when the center limit switch SC contacts with theinterception plate 102, the SC is turned off to cut off power supply to themotor 101, and accordingly, theinterception plate 102 is stopped at the central region of theintake 14 to block it. - When the user selects a terminal 'B' of the US in order to block the second opening region of the
intake 14, power is applied to themotor 101 through the back limit switch SB electrically connected with the terminal 'B' and themotor 101 is driven by power to move theinterception plate 102 to the second opening region. At this time, when theinterception plate 102 comes in contact with the back limit switch SB, the SB cuts off power supply to themotor 101. Namely, when the SB contacts with theinterception plate 102, it cuts off power supply to themotor 101, and accordingly, theinterception plate 102 is stopped at the second opening region of theintake 14 to block it. - In this manner, the intake controlling device of the kitchen range hood in accordance with the first embodiment of the present invention freely moves the interception plate to the first opening region, the central region and the second opening region of the intake to increase the uptake rate of the kitchen range hood and thus, completely discharge heat, contaminated air and gases to outside.
- Preferably, the front limit switch SF is fixedly installed at the left side of the intake controlling device, the center limit switch SC is fixedly installed at the center of the intake controlling device and the back limit switch SB is fixedly installed at the right side of the intake controlling device.
- An intake controlling device capable of completely discharge heat, contaminated gases to outside by increasing the uptake rate of the kitchen range hood by automatically moving the
interception plate 102 to one of the first opening region, the central region and the second opening region according to a burner used in the kitchen range, rather than depending on user's selection, in accordance with the second embodiment of the present invention will now be described in detail with reference toFigures 6 to 8 . -
Figure 6 shows a detailed construction of an intake controlling device of a kitchen range hood in accordance with a second embodiment of the present invention. - As shown in
Figure 6 , an intake controlling device in accordance with the second embodiment of the present invention includes: aninterception plate 102 installed at ahood cover 15 and selectively blocking opening regions of anintake 14;sensors 202 and 203 for sensing a current cooking position (e.g., the front burner 21) of thekitchen range 20 and generating a sense signal; amotor driving unit 201 for generating a motor drive signal for automatically moving theinterception plate 102 to a specific region (e.g., the second opening region) of theintake 14 according to the sense signal; and amotor 101 for moving theinterception plate 102 to a specific region (e.g., the second opening region) of theintake 14 according to the motor drive signal in order to block the specific region (e.g., the first opening region is opened and the second opening region is blocked) of theintake 14. - Sensing of the current cooking position of the
kitchen range 20 can be implemented in various manners. For example, the first temperature sensor 202 is installed corresponding to an upper portion of thefront burner 21 of thekitchen range 20, senses a temperature of thefront burner 21, and outputs a first temperatures sense signal, and thesecond temperature sensor 203 is installed corresponding to an upper position of theback burner 22 of thekitchen range 20, senses a temperature of theback burner 22 and outputs a second temperature sense signal. Herein, preferably, an infrared sensor for sensing heat and steam generated from thekitchen range 20 is used as the first andsecond temperature sensors 202 and 203. - When the
motor driving unit 201 receives the first temperature sense signal, it moves theinterception plate 102 to the second opening region. When themotor driving unit 201 receives the second temperature sense signal, it moves theinterception plate 102 to the first opening region. When themotor driving unit 201 receives both first and second temperature sense signals, it moves theinterception plate 102 to the central opening region. - A controller for logically operating the first temperature sense signal, the second temperature sense signal, a switching signal of the front limit switch and a switching signal of the back limit switch and controlling the
interception plate 102 can be added to themotor driving unit 201. - The construction of the controller for logically operating the first temperature sense signal (IF), the second temperature sense signal (IB), a switching signal of the front limit switch (a first interception sense signal (SF1)) and a switching signal of the back limit switch (a second interception sense signal (SB1)) and controlling the
interception plate 102 will be described in detail with reference toFigure 7 . -
Figure 7 is a circuit diagram of a controller of the intake controlling device in accordance with the second embodiment of the present invention. - With reference to
Figure 7 , the controller includes: a first inverter IN1 for inverting the first interception sense signal (SF1); a first AND gate (AN1) for ANDing an output signal of the first inverter (IN1) and the second temperature sense signal (IB) of the second temperature sensor 203; a second inverter IN2 for inverting the second interception sense signal (SB1); a second AND gate (AN2) for ANDing an output signal of the second inverter IN2 and the first temperature sense signal (IF) of the first temperature sensor 202; a third inverter for inverting the second temperature sense signal (IB); a fourth inverter IN4 for inverting the first temperature sense signal (IF); a third AND gate (AN3) for ANDing an output signal of the third inverter IN3 and the first temperature sense signal (IF); a fourth AND gate (AN4) for ANDing an output signal of the fourth inverter (IN4) and the second temperature sense signal (IB); a first OR gate (OR1) for ORing an output signal of the third AND gate (AN3) and an output signal of the fourth AND gate (AN4); a second OR gate (OR2) for ORing an output signal of the first AND gate (AN1) and an output signal of the second AND gate (AN2); a fifth AND gate (AN5) for ANDing an output signal of the first OR gate (OR1) and an output signal of the second OR gate (OR2); and a motor control switch (MS) for outputting a motor drive signal to the motor 101 according to an output signal of the fifth AND gate (AN5). - When the motor control switch (MS) receives an output signal '1' from the fifth AND gate (AN5), it applies power to the
motor 101. When the motor control switch (MS) receives an output signal '0' from the fifth AND gate (AN5), it cuts off power supply to themotor 101. - The operation of the controller of the
intake controlling device 200 will be described in detail with reference toFigures 7 and8 . -
Figure 8 is a truth table indicating an output value of the controller of the intake controlling device in accordance with the second embodiment of the present invention. - When a user is cooking only with the
front burner 21 of thekitchen range 20, the first temperature sensor 202 senses heat or steam generated during cooking and outputs a first temperature sense signal as '1'. In this case, thesecond temperature sensor 203 installed at an upper side of theback burner 22 of thekitchen range 20 does not sense heat and outputs a second temperature sense signal as '0'. At this time, when theinterception plate 102 is sensed, the front limit switch (SF) outputs a first interception sense signal as '1', and if theinterception plate 102 is not sensed, the front limit switch (SF) outputs the second interception sense signal as '0'. - The controller receives the first and second temperature sense signals IF and IB and the first and second interception sense signals SF1 and SB1, logically operates them, and outputs a motor drive signal to the
motor 1. - For example, the first inverter IN1 inverts the first interception signal SF1 to output an output signal '1', and the first AND gate AN1 ANDs the first interception sense signal SF1 outputted from the first inverter IN1 and the temperature sense signal IB and outputs an output signal '0'.
- The second inverter IN2 inverts the second interception sense signal SB1 to output an output signal '1' and the second AND gate AN2 ANDs the second interception sense signal SB1 outputted from the second inverter IN2 and the first temperature sense signal IF and outputs an output signal '1'.
- The third AND gate AN3 ANDs the second temperature sense signal '1' inputted after being inverted in the third inverter IN3 and the first temperature sense signal '1', and outputs an output signal '1'.
- The forth AND gate AN4 ANDs the first temperature sense signal '0' inputted after being inverted in the fourth inverter IN4 and the second temperature sense signal '0', and outputs an output signal '0'.
- The first OR gate OR1 ORs output signals of the third AND gate AN3 and the fourth AND gate AN4 and outputs an output signal '1'.
- The second OR gate OR2 ORs output signals of the first AND gate AN1 and the second AND gate AN2, and outputs an output signal '1'.
- The fifth AND gate AN5 ANDs output signals of the first and second OR gates OR1 and OR2, and outputs an output signal '1' to the motor control switch MS. Then, the motor control signal MS applies power to the
motor 101 according to the output signal '1' of the fifth AND gate AN5. - When the
interception plate 102 is sensed by the back limit switch (SB) and the second interception sense signal '1' is outputted, the second AND gate AN2 outputs an output signal '0'. The second OR gate OR2 ORs the output signal '0' outputted from the first AND gate AN1 and the output signal '0' outputted from the second AND gate AN2, and outputs an output signal '0'. Then, the fifth AND gate AN5 outputs the output signal '0' to the motor control switch MS. Accordingly, the motor control switch MS cuts off power supply to themotor 101 according to the output signal '0' of the fifth AND gate AN5. - When the controller receives the first temperature sense signal '1' and the second temperature sense signal '1', it stops the
motor 101 at the central region of theintake 14 in order to open both the first and second opening regions. Herein, theinterception plate 102 of the intake controlling device is initially positioned at the central region. - As so far described, the intake controlling device of the kitchen range hood of the present invention has many advantages.
- That is, for example, the opening regions of the intake of the kitchen range hood are selectively opened and blocked according to a position where a smell and steam is generated during a cooking process, to thereby increase the uptake rate. Accordingly, performance of discharging heat and contaminated air of the kitchen range hood can be maximized, and thus, an indoor environment can be maintained to be agreeable.
