Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a range hood in which an opening of a hood main body can be extended toward a range to improve an effect of collecting oil smoke emitted from the range.

[0002]

2. Description of the Related Art Conventionally, a range hood is installed at a relatively high position above the range, and oil smoke rising from the range is sucked and exhausted from an opening on the lower surface of the hood body. If you want only the suction efficiency of the range hood, it is better to install it in a low position on the range so that the opening on the bottom surface of the hood body that serves as a suction port approaches the range as much as possible, but if you install it too low position The range itself is located directly above the range, which hinders cooking. Therefore, the conventional range hood is often installed at a height of about 800 to 850 mm from the top surface of the range table even if the collection efficiency is slightly reduced.

[0003]

In order to achieve both the collection efficiency of the range hood and the workability of cooking, the applicant of the present application slidably fits a tubular hood into the opening on the lower surface of the hood body and We have developed a range hood that can be moved up and down manually or by an electric motor. This range hood enhances the efficiency of collecting oil and smoke coming out of the range by lowering the lifting hood fitted to the opening of the hood body close to the range, and when not cooking, the lifting hood up to the hood body. It is raised and stored. However, even in the above range hood, when the elevating hood is used by lowering it, the kitchen hood and the cooking utensil placed on the range are cut off because the lowered elevating hood cuts the gap between the cooker and the range. There was a problem that I could not see directly. In particular, when the shape of the lifting hood is a boot shape with the lower end opening widened, there is a problem that the range is almost invisible due to the blocking by the widening portion.

The object of the present invention is to enhance the efficiency of collecting the range by lowering and raising the lifting hood, and to secure the visual field on the range that the cook can see when the lifting hood is lowered so that cooking can be performed without any trouble. It is to be able to do it.

[0005]

In order to solve the above-mentioned problems, the range hood of the present invention comprises a substantially box-shaped hood body having an opening on the lower surface, and an elevating hood for extending the hood body downward. The lifting hood is slidably fitted so that the lifting hood can be lowered and raised between the hood body and a position lower than the user's line of sight, and a window is opened on the lower peripheral surface of the lifting hood. The part is covered with a transparent plate.

[0006]

According to the above means, the elevating hood extending from the hood body is slidably fitted in the lower opening of the hood body. Therefore, by lowering and raising the lifting hood, the suction opening constituted by the lower end opening of the lifting hood is moved between the opening of the range hood and a position lower than the user's line of sight, and the height of the suction opening is increased. Adjustment is performed. For example, when the lifting hood is lowered, the lower end opening of the lifting hood, which is a suction port, approaches the range to improve the collection efficiency by the range hood, and to perform cooking between the lower end of the lifting hood and the range. Required space is secured. Further, the elevating hood is housed in such a manner that it is fitted into the opening on the lower surface of the hood main body by raising it to the hood main body.

A window portion covered with a transparent plate is provided on the lower peripheral surface of the lifting hood. Therefore, the window of the lifting hood is located at a position lower than the line of sight of the user in the lowered state, that is, the line of sight of the user who looks at the cooktop, and thus the view of the cooker's view on the cooktop is transparent. Secured through a window covered with.

[0008]

As described above, according to the present invention, the lifting hood is vertically slidably fitted in the opening of the hood body,
Since a window covered with a transparent plate is opened on the lower peripheral surface of this lifting hood, it is possible to lower the lifting hood during cooking where a lot of oil smoke is generated, and enhance the collection effect of the range hood. At the same time, even when the lifting hood is lowered, the field of view on the range can be secured through the window portion, so that cooking can be performed without any trouble.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The range hood shown in FIGS. 1 and 2 is installed above the wall surface b of the cooking chamber where the range table a is installed,
An exhaust fan unit 4 that is installed and installed in an exhaust passage c that penetrates the wall surface b and communicates with the outside, and a hood body 1 that is installed along the wall surface b so as to cover the exhaust fan unit 4;
Also, the lifting hood 2 is slidably fitted into the surface opening of the hood body 1.

The hood main body 1 is a box made of a steel plate having an open lower surface, and an exhaust port 1b is formed on the rear surface of the hood main body so as to project into the exhaust passage c of the wall surface b. Further, a fan 42 that is rotated by the drive motor 41 is provided in the shaft core portion inside the exhaust port 1b, and the bell mouth 4 is provided in front of and behind the fan 42.
The exhaust fan unit 4 is configured by including the shutter 3 and the shutter 44. The exhaust fan unit 4 may be a sirocco type Yuan unit.

In the opening 1a of the hood body 1 described above, an elevating hood 2 having a U-shaped cross section and having a rear opening is vertically slidably fitted. The lifting hood 2 is formed by bending a steel plate into a U-shaped cross section, and has a slide portion 2a that fits inside the opening 1a of the hood body 1 and an expansion portion 2b formed at the lower end of the slide portion 2a. And make up. The expansion portion 2b is formed by projecting the front surface of the lower end of the slide portion 2a and the left and right side surfaces in a slanted manner, and constitutes a suction port 2c that expands downward. As a result, the lifting hood 2 has a shape similar to that of a so-called boot hood. On the other hand, the slide portion 2a of the lifting hood 2 is formed to have substantially the same height as the entire height of the hood body 1. Therefore, when all of the slide portions 2a are fitted inside the hood body 2, the expanded portion 2b is in a stored state in which it is abutted under the opening 1a at the lower end of the hood body 1, and in this stored state, the hood body 1 and the lifting hood are held. 2 forms a normal boot hood. Rails 10 extending in the vertical direction are attached to both side surfaces of the lifting hood 2. The rail 10 is slidably fitted with rail guides 9 provided on both inner side surfaces of the hood body 1. Then, as described above, the slide portion 2a
By engaging the rail 10 with the rail guide 9 when the main body 1 is fitted in the hood 2,
Is supported in the hood body 1 so as to be slidable up and down.

A fixing bracket 7 is provided on the inner surface of the upper portion of the lifting hood 2.
Is attached and fixed, and the lower end of the suspension wire 6 is fixed to the fixing metal fitting 7. The suspension wire 6 is passed through a pulley 7 mounted on the upper surface inside the hood body 1 and folded back downward, and a weight 8 is attached to the other end of the suspension wire 6 to suspend it. The weight 8 is for maintaining a weight balance with respect to the elevating hood 2. By maintaining the weight balance between the two, 8, the elevating hood 2 is lightly moved up and down manually and stopped at a desired height. You will be able to do it. In addition, the lifting hood 2 is in a state of being housed in the hood body 1 as shown by the phantom line in FIG. 1 at the raised position, and is lower than the line of sight of the cooker as shown by the solid line at the lowered position. At the position, it stops at a height of about 200 mm from the upper surface of the range stand a. The lifting hood 2 described above may be configured to automatically move up and down by rotating a pulley that winds the wire 6 with an electric motor. Further, although the elevating hood 2 is fitted inside the hood body 1, the elevating hood 2 may be constructed so as to be raised and lowered in a state of being fitted outside the hood body 1.

A window portion 3 is opened on the inclined surface of the expanding portion 2b projecting toward the front side at the lower end portion of the lifting hood 2 described above. The window part 3 is the expanded part 2b of the lift hood 2 which has been lowered.
This is for securing the field of view of the cooker blocked by the cooking so that cooking can be performed. The inclined surface of the expanding portion 2b is opened to the front, and the glass plate 3b is applied to the back side of the opening 3a. It is configured by covering. As shown in FIG. 3, the glass plate 3b is attached to the outer edge of the glass plate 3b by bending the latching piece 3c having an L-shaped cross section provided along the back side of the opening 3a toward the inside. It is done by stopping. As shown in FIG. 4, the window portion 3 opened in the widening portion 2b of the lifting hood 2 is opened on both the left and right side inclined surfaces together with the inclined surface on the front surface to secure a wider field of view on the upper surface of the range stand a. You can do it.

According to the range hood constructed as described above, the elevating hood 2 can be easily moved up and down manually as needed. For example, when the elevating hood 2 is lowered, a space required for placing a cooking utensil such as a pan or a frying pan is secured between the lower end of the elevating hood 2 and the upper surface of the range a, and at the same time, the oil smoke suction port 2c. The lower end opening of the lifting hood 2 that comes into contact with the ranges a1 and a2 approaches and efficiently sucks the oil smoke emitted from the pan or frying pan.

On the other hand, as described above, the expanding portion 2b formed on the lower peripheral surface of the elevating hood 2 is positioned lower than the user's line of sight when the elevating hood 2 is lowered, and blocks the view of the cook. It becomes the form. However, since the window portion 3 is opened in the expanded portion 2b of the lifting hood 2 as described above, even if the lifting hood 2 is lowered to increase the efficiency of collecting oil smoke, the window portion 3 can be opened. It is possible to perform cooking without any trouble while observing the state of the pan or frying pan to be placed on the microwave ovens a1 and a2 for cooking. The raising / lowering hood of the range hood described above has a widened portion 2b projecting from the lower peripheral surface in order to improve the collection efficiency, and a window 3 is opened in the widened portion 2b. However, the elevating hood does not necessarily have to be provided with the widening portion, and may be configured to have the same width as the range hood main body over the entire length, and the window portion may be opened on the lower peripheral surface thereof.
