Description

[Detailed description of the invention] (Field of industrial application) The invention is a deep range hood, specifically, the front plate is pushed up from the bottom of the main body, the upper part engages with the main body, and the lower part is screwed. This is an idea related to range hoods.

(Conventional technology and its problems) It is important to harmonize the shape and color of a deep range hood that forms part of the kitchen interior with the surrounding kitchen furniture (for example, system kitchen cabinets, etc.). Therefore, it was necessary to install the range hood with the top end close to the kitchen ceiling.

However, with conventional range hoods, the main unit is attached to the wall, and then the front plate is pushed down from the top of the main unit to the bottom to engage the upper part of the front plate, and the lower part is pressed against the main unit and fixed with screws. .

However, with the above method of installing the front plate, if the range hood is installed near the ceiling of the kitchen, the front plate cannot be attached, so the front plate must be pushed up from the bottom to the top to engage the top of the front plate. There are ways to attach it.

However, with this method, when removing the front plate, if you loosen the screws and pull the bottom of the front plate towards you, there is a risk that the front plate will fall as soon as it is pulled towards you.

Furthermore, in the case of a range hood in which the upper end surface of the main body and the front plate are substantially flush, as in the device disclosed in Utility Model Application No. 60-35150, the main body itself is also formed with a large height. Therefore, the upper flange, which engages with the upper part of the front plate, has a large width in the vertical direction, and the upper flange is provided with an engaging hole and a bag-shaped receiving part.

However, in the above prior art, the front plate and the upper end surface of the main body are substantially flush with each other and the height is high, so when performing top exhaust where the exhaust duct is connected to the top plate of the main body, the range hood must be placed in a specified position relative to the range. This has the disadvantages of having to be closer than the height position, and also having to install a separate curtain plate or the like to hide the exhaust duct exposed above the main body.

(Problem to be solved by the invention) In view of the above problems, the problem of the invention is to loosen the tightening screws when removing the front plate of a range hood that is installed by pushing up the front plate from the bottom of the main body. To provide a range hood which prevents the front plate from falling even when the lower side of the front plate is pulled toward you and can be equipped with a means for preventing the front plate from falling even on a low-height main body. It is in.

(Means for Solving the Problems) The technical means taken by the present invention to achieve the above problems are as follows:
In a range hood consisting of a removable front plate 2 that covers the front surface of the main body, fitting pieces 4 and 4' are provided inside the upper flange 1a formed at the upper part of the front opening of the main body 1. , hanging pieces 3, 3' are provided on the upper sides of the flanges 1b, 1'b on both the left and right sides to protrude forward, and the flanges 1b, 1'b on both sides
Engagement plates 5, 5' with tightening screws 9, 9' screwed onto the lower side of 1'b are provided to protrude rearward, and the other front plate 2
An upper flange 2a is formed on the upper back side of the holder to be hooked to the hooking pieces 3, 3', and the upper flange 2a has fitting recesses 6, 6' into which the fitting pieces 4, 4 are fitted. Further, on the lower side of the left and right side flanges 2b, 2'b formed on the back side of the front plate 2, the engaging plates 5, 5' are fitted with tightening screws 9, 9'. It has a configuration in which coupling brackets 7 and 7' are provided.

(Function) When installing the range hood in harmony with a hanging cabinet such as a system kitchen, first attach the main unit to the wall near the ceiling of the kitchen, and then move the front plate from the bottom of the main unit to the top. By pushing up, the fitting piece of the main body is fitted into the fitting recess. At this time, the upper flange on the back side of the front plate is hooked to the hook piece.

Then, the lower part of the front plate is pressed against the main body side, and the engagement bracket of the front plate is engaged with the engagement plate of the main body, and then fixed with a tightening screw.

In addition, when removing the front plate from the main body, loosen the tightening screws and pull the lower part of the front plate toward you to disengage the engagement plate of the main body and the engagement bracket of the front plate. Then, the fitting recess also comes off, leaving it latched to the main body only by the latching piece.

Then, lift the front plate upward to remove it from the main body.

(Effects of the invention) The invention has the following effects due to the above configuration.

When removing the front plate from the main body, even if you loosen the tightening screws and pull the lower part of the main body towards you, the upper flange on the back of the front plate is hooked to the latch piece on the main body, so the lower part of the front plate cannot be removed. This will prevent the front plate from falling when you pull it towards you.

When the range hood body is attached to a wall near the ceiling, it can be easily attached by pushing up the front plate from the bottom of the body to the top.

The hanging pieces that prevent the front plate from falling are formed protruding from the flanges on both the left and right sides of the main body, so it is only necessary to form fitting pieces on the upper flange of the main body, so the width of the upper flange is reduced compared to the conventional technology. (Height) should be narrow, so the height of the main body is lower (about 600mm) compared to the conventional product (about 600mm).
400mm), it is possible to secure a space (opening) for the exhaust unit to enter and exit at the front of the main unit. Therefore, it is possible to provide a range hood that can exhaust air from the top by attaching a high front plate similar to the conventional product to a low-height main body and partitioning a space for attaching an exhaust duct to the upper part of the main body.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.
