Abstract

PURPOSE:To perform an efficient collection of oily smoke, exhaust gas and water vapor or the like without being leaked from a main body of a range hood and to prevent a trouble of a front plate driving device by a method wherein the front plate driving device is installed at a top plate of the main body of the range hood. CONSTITUTION:As an operation switch of a main body 1 of a range hood is turned on, air on a gas table is inducted into a main body 1 of the range hood 1 under an operation of an air blower 2. Concurrently, a front plate driving electric motor 7 is rotated normally, its rotating movement retracts a supporting rail 6 rearwardly through a pinion 8 and a rack 9. Since the supporting rail 6 is connected to a part higher than a supporting point 4 for the front plate, a lower end of the front plate 3 is pushed out forwardly in a reverse direction. As the supporting rail 6 is moved by a predetermined distance, a limit switch 12 turns off a power supply for a front plate driving electric motor 7 and stops the moving action of the supporting rail 6. In this way, the ascending oily smoke, exhaust gas and water vapor or the like are sucked into the main body 1 of the range hood. The oily smoke or the like are efficiently collected by the front plate driving device 10 installed at a top surface of the main body 1 of the range hood 1.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a range hood that exhausts oil smoke generated during cooking in a kitchen gas range to the outside, and whose front plate opens and closes in conjunction with the operation of the hood.

2. Prior Art Conventionally, this type of range hood has generally been shown in FIGS.
The configuration was as shown in the figure. As shown in the figure, oil smoke,
A hood body 101 has a built-in blower 102 for discharging exhaust gas, steam, etc., and has an open front and bottom surface, an upper end 104 of which is rotatably supported by a front opening 103 of the hood body 101, and a lower end 105 of the hood body 101. is the hood body 1
A front plate 106 is formed to be able to move in and out of the front plate 101, and is connected to a lower end 105 of this front plate 106, and is fixed to an inner surface 107 of the hood body 101, so that the lower end H105 of the front plate 106 is connected to the lower end 105 of the front plate 106. A drive unit 108 for the front plate 106 is moved forward and backward relative to the hood body 101, and the lower end 105 is supported by the drive unit 108 held by the hood body 101, and has a rail 109 that can move forward and backward. and a switch (not shown) that operates the blower 102 and the drive device unit 108 in conjunction with each other.
It was composed of.

In such a range hood, when using equipment that uses fire such as a gas range, when the range hood is turned on, the blower 102 is operated and at the same time the drive unit 1 is turned on.
08, the lower end 105 of the front plate 106 is pushed forward and stops at an arbitrary position, covering a wide area above the hot-burning equipment, efficiently collecting oil smoke, exhaust gas, rk, etc., and exhausting it into the room. do. When the hot equipment is stopped, when the main switch (not shown) of the needle body 101 is turned off, the blower 102 is stopped and at the same time the front plate 10 (lower end 1
05 is pulled back by the drive unit 108, and the main body 10 is pulled back by the drive unit 108, and the main body 10
1 to improve the aesthetics of the kitchen.

Problems to be Solved by the Invention In such a conventional configuration, when cooking is carried out using no open flame equipment, rising oil smoke, exhaust soot, water vapor, etc. are drawn into the hood 1 by the blower 102. However, the drive unit 108 provided on the inner surface 107 of the hood body 101 may be directly hit by oil smoke, exhaust gas, water vapor, etc., and may have an adverse effect on the mechanical parts and electrical parts (2) of the drive unit 108. In addition, the drive device unit 108 has the problem that it may cause a malfunction.
Since it is provided on the inner surface 107 of the hood body 10
This method also has the drawback of reducing the suction area of the opening on the lower surface of No. 1, reducing the efficiency of collecting exhaust gas such as oil smoke, exhaust gas, and water vapor. Furthermore, if it is necessary to match the depth of the hood main body 101 to the dimensions of the hanging cabinet to improve the aesthetics, and if you want to reduce the depth of the hood main body 101, the rail 109 connected to the drive unit 108 may be lengthened so that the front By increasing the moving distance of the plate, the front plate 106 must cover the tip of the hot equipment. Therefore, there is also a drawback that the drive device unit 108 must be made new each time the depth dimension of the hood body 101 is changed.

The present invention aims to solve these drawbacks, and is designed to prevent oily smoke from being produced when cooking using hot-burning equipment.

Exhaust gas and water vapor can be efficiently discharged, the operation of the front plate 106 is automatically and smoothly performed in conjunction with the main switch, and the drive unit 108 can be connected to the hood body 10.
The purpose of this is to allow common use regardless of the depth dimension of 1.

Means for Solving the Problems In order to solve the problems, the present invention provides a hood body with an opening on the front and lower surfaces and a built-in blower, and an upper end rotatably supported in the front opening of the hood body. and a front plate whose lower end is formed to be able to move in and out of the hood main body, and by a front plate drive device unit connected to the upper end of the front plate and fixed to the top surface of the hood main body, The range hood is configured such that the upper end of the front plate moves forward and backward with respect to the hood main body.

With this configuration, when cooking using hot-burning equipment, the rising oil smoke, exhaust gas, water vapor, etc. are drawn into the inside of the hood body by the suction port of sufficient size without hitting the drive unit. This will prevent oil smoke from spreading outside the hood body. Furthermore, even when manufacturing a range hood with a depth that matches a shallow wall cabinet, the front plate driving device can drive the front plate over a long distance, so the front plate driving device can be shared.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. As shown in the figure, a front plate 3 is provided in connection with a front plate drive device 10 in order to open and close a front opening of a hood main body 1 having a built-in blower 2 and open front and lower surfaces. Further, the front plate 3 is rotatably supported on the hood body 1 by a support lever 4 with one end serving as a fulcrum.

Further, the front plate 3 is connected to the upper front end of a support rail 6, which is supported by a metal fitting 5 provided above the support lever 4 so as to be movable in a forward and backward manner relative to the hood body 1. A front plate driving electric motor 7 having a binion 8 is provided on the upper surface of the hood main body 1 at a position facing the support rail 6, and a rack 9 is provided on the support rail 6, and these binions 8 and racks 9 are engaged. The front plate 3 is moved forward or backward by forward or reverse rotation of the front plate driving electric motor 7. Further, a limit switch 12 is provided on the top of the hood body 1 to turn off the power to the front plate driving electric motor 7 when the support rail 6 moves forward or backward by a predetermined distance. The support rail 6, the front plate driving electric motor 7, the binion 8. Rack 9
．． The limit switch 12 constitutes a drive unit 10 for the front plate 3.

In the above configuration, when the operation switch 11 of the hood body 1 is turned on, the air above the gas staple is drawn into the inside of the hood body 1 by the blower 2. At the same time, the front plate driving electric motor 7 rotates in the forward direction, and the rotational movement of the front plate driving electric motor 7 causes the pinion 8. The support rail 6 is pulled rearward via the rack 9. Since the support rail 6 is connected above the support point 4 of the front plate, the lower end of the front plate 3 is pushed forward. When the support rail 6 moves a predetermined distance, the limit switch 1
2 turns off the power to the front plate driving electric motor 7 and stops the movement of the support rail 6. Then, the support rail 5 is fixed at this position using a solenoid (not shown) or the like.

As described above, according to this embodiment, the oil smoke, exhaust gas, water vapor, etc. that rise when a gas range is used are attracted to the inside of the hood body 1. Since there is no unit 10, oil smoke etc. can be collected efficiently without waste, and the electric motor 7 for driving the front plate
．． Since electrical components such as the support rail 6 and mechanical components are not in the ventilation path, troubles such as failures caused by electrical components and mechanical components being contaminated with oil smoke can be prevented. Further, since the distance between the fulcrum of the front plate 3 and the fulcrum of the support rail 6 is short, the front plate 3 can be opened and closed with a short stroke of the support rail. As a result, even if the depth dimension of the hood body 1 is small, the front plate drive unit 10 can be used in common as is.

Effects of the Invention As is clear from the description of the embodiments above, according to the present invention, the front plate driving device unit is provided on the top surface of the hood body l, so that oil smoke, exhaust gas, and water vapor rising from a gas range etc. etc. are efficiently collected without leaking from the hood itself. Furthermore, since there is no front plate drive unit in the exhaust passage, failure of the front plate drive unit can be prevented and smooth operation can be achieved. Furthermore, since the stroke of the front plate drive unit can be shortened, the front plate drive unit can be used in common even if the depth dimension of the hood body changes.
