Description

  In the present invention, a blower is installed vertically in a hood body having a deep capture space for sucking and collecting polluted air such as hot and cold smoke rising from cooking utensils and cooking pans during cooking. It relates to the deep type range hood.

The range hood is called a deep range hood except for a thin range hood with a shallow capture space for sucking and collecting contaminated air.
This deep type range hood has a blower installed vertically in a front direction inside a hood body having a capture space deeply formed in the height direction (kitchen ceiling direction).
The deep range hood has a rectifying plate placed in an obliquely downward posture toward the downward opening side of the hood body in front of the suction port of the blower that is open facing the front side (cooker side) of the hood body. Furthermore, a partition plate for partitioning the downward opening side of the hood body from the blower side is disposed from the bottom of the current plate toward the back plate of the hood body (Patent Document 1 and Patent Document 2, etc.) See).
That is, the conventional deep type range hood is formed in a substantially horizontally long rectangular shape with a width corresponding to the height of the fan casing of the blower and a width slightly smaller than the width between the side plates of the hood body. The rectifying plate is disposed in an obliquely downward posture in front of the suction port of the blower.
As a result, the air is vigorously increased by the suction gaps formed between the peripheral edges of the current plate, the partition plate, and the upper surface plate and both side surface plates of the hood body. The air is drawn into the back (back side) of the current plate.
JP 2000-74441 A (see paragraph numbers 0008, 0011, 0022 and FIG. 4 in the specification) Japanese Patent Laid-Open No. 2000-74442 (see paragraph numbers 0008 and 0012 and FIG. 1 in the specification)

By the way, in the conventional deep type range hood, the contaminated air sucked into the capture space from the downward opening of the hood body is collected along the rectifying plate in an obliquely downward posture from the suction gap of each peripheral edge of the blower. It is possible to promptly flow in the direction of the suction port and to exhaust the air from the suction port through the exhaust duct.
However, the hood body has a suction force (suction collection force) that prevents the contaminated air that rises from the heating cooker or cooking pan from diffusing to the kitchen ceiling, etc. It cannot be generated effectively in the opening. That is, there remains a problem that the original capture performance required for the range hood is not improved such that the contaminated air is surely attracted and collected from the downward opening to the capture space without taking away the contaminated air.

  As a measure for generating a strong suction force in the downward opening of the hood body, it is conceivable to increase the output of the fan motor of the blower. However, a motor with a large output is not only expensive but also large. Because of this tendency, it is difficult to incorporate it into the fan casing of the current blower, and the feasibility is poor.

  Therefore, in order to solve such problems, the inventor of the present application has repeated research and development to arrive at the idea of the present invention, and without increasing the main force of the fan motor of the blower, and in addition to the current plate itself. An object of the present invention is to provide an improved deep range hood which can effectively capture the contaminated air by effectively propagating the suction force of the blower to the downward opening of the hood body without adding a great improvement.

In order to solve the above-described problem, in the present invention, a blower is installed vertically in a capture space of a hood body that opens downward, and a rectifying plate is disposed in front of the suction port of the blower. A deep range hood with suction gaps along each peripheral edge,
An airflow suppression member is provided between the current plate and the opening wall surface of the blower in which the suction port is opened, and the airflow suppression member is located on the downward opening side of the hood body, It has a contact portion of the contaminated air that is formed to rise from the opening wall surface toward the rectifying plate.
Here, when the rectifying plate is attached in an obliquely downward posture toward the downward opening of the hood portion, the abutment is made in accordance with a height substantially along the rectifying plate in the obliquely downward posture. It is preferable that the part is raised and formed.

In addition, it is preferable that the upper surface plate is provided with a hanging member that narrows a suction gap formed between the upper edge of the current plate and the upper surface plate of the hood body.
Furthermore, it is preferable that a partition plate for partitioning the downward opening side of the hood body and the blower side is disposed from the bottom of the rectifying plate toward the back plate of the hood body.
The straightening plate has a vertical width corresponding to the height of the fan casing of the blower, and is formed in a substantially horizontally long rectangular shape with a horizontal width slightly narrower than a horizontal width dimension between both side plates of the hood body. As a result, a suction gap is formed between each peripheral edge of the rectifying plate, the partition plate, and the top plate and both side plates of the hood body.

According to such a configuration, due to the suction force of the blower, polluted air such as fumes and oil smoke sucked into the capture space from the downward opening of the hood body hits the current plate, and each side around the current plate From the suction gap formed along the edge portion, the air is sucked at a rapid increase in the flow rate to the back side of the current plate where the blower is installed.
Then, out of the polluted air that has been sucked into the back side of the current plate, it is located on the downward opening side of the hood body where the abutting wall part of the airflow suppression member arranged on the back side of the current plate is not provided. The contaminated air sucked from the suction gap on the lower side of the rectifying plate (lower side of the airflow suppression member) flows in the direction of the suction port of the blower without receiving airflow resistance (airflow friction).
On the other hand, the contaminated air sucked in from the suction ports on the peripheral edges of the current plate, excluding the lower side of the current plate where the wall is raised in front of the suction port, flows into the wall. Upon receiving the contact resistance (friction) of the air flow that suppresses the suction flow by the bump, the air flows toward the suction port of the blower.
Thereby, the suction force of the blower is more propagated to the suction gap side formed on the lower side of the rectifying plate where the flow is performed quickly (smoothly) toward the suction port of the contaminated air. . In other words, the suction force (suction collection force) to draw the polluted air that soars from the heating cooker or cooking pan in the direction of the kitchen ceiling, etc. efficiently is applied to the downward opening of the hood body, It can be propagated intensively.

  In the present invention, the airflow suppression member includes a bell mouth for forming the suction port.

  According to such a configuration, when wiping off dirt such as adhered oil (oil and fat) or washing it with a sink or the like, the airflow suppression member is removed from the hood body, so that the suction port of the blower has an inward trumpet shape. The bell mouth for opening to the outside can be taken out of the hood. As a result, daily maintenance can be improved.

Since the deep range hood of the present invention is configured as described above, the suction force of the blower can be efficiently and intensively propagated to the downward opening of the hood body, such as a heating cooker or a cooking pan. It is possible to generate a strong suction force (suction trapping force) in the downward opening for drawing the polluted air soaring from the kitchen ceiling without escaping it.
As a result, the airflow suppression member is provided between the current plate and the opening wall surface of the blower in which the suction port is opened, and the contaminated air is reliably drawn from the downward opening to the capture space without being trapped. It is possible to significantly improve the original capture performance required for range hoods.
That is, without increasing the main power of the fan motor of the blower, and without greatly improving the rectifying plate itself, the suction force of the blower is efficiently and intensively propagated to the downward opening of the hood body. Without trapping contaminated air to the kitchen ceiling or the like, it can be reliably drawn into the downward opening and sucked into the collection space.

Moreover, the bell mouth for forming the suction port of a fan can be removed from a hood body by removing an airflow suppression member from a hood body.
As a result, it is possible to expect improvement in daily maintenance such as wiping off dirt such as attached oil (oils and fats) or washing with a sink or the like.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.

[Description of operation]
Next, the action of the range hood A according to the present embodiment in which the airflow suppression member 13 formed in this way is attached to the front wall 15 of the fan casing 2a between the rectifying plate 4 and the transmitter 2 is provided. A brief explanation will be given. Here, description will be made with reference to FIGS. 1 and 2 as appropriate.
Contaminated air G such as hot and cold smoke or oil smoke sucked and collected from the downward opening 6 of the hood body 1 by the suction force of the blower 2 strikes the rectifying plate 4, and each peripheral edge 4 around the rectifying plate 4. When the suction gaps S-1 to S-3 formed along the lines -1 to 4-3 are sucked into the back side of the rectifying plate 4 with a rapid increase in the flow velocity and flow toward the suction port 3, FIG. As shown in FIG. 4, the contaminated air G− sucked in from the lower edge portion 4-2 side (suction gap S-2 side) of the rectifying plate 4 where the abutting walls 13b and 13c of the airflow suppression member 13 are not raised and provided. 1 flows in the direction of the suction port 3 without receiving contact resistance (friction) such as hitting an obstacle, and is sucked into the fan casing 2a from the suction port 3 and exhausted to the outside through the exhaust duct B. The
On the other hand, the upper edge part 4-1 and both side edge parts 4-3 side (suction gaps S-1, S) of the rectifying plate 4 provided with the abutting wall parts 13b, 13c rising up before the suction port 3 are provided. The contaminated air G-2 sucked from the (-3 side) is restrained from being sucked in the direction of the suction port 3 by contact so as to abut against the abutting portions 13b and 13c. That is, it flows in the direction of the suction port 3 while receiving contact resistance that reduces the suction flow velocity due to the contact with the contact portions 13b and 13c that become obstacles to the flow.
As a result, the suction force from the suction port 3 is such that the flow of the contaminated air G-1 from the suction gap S-2 toward the suction port 3 is performed quickly (smoothly). Will be propagated more toward the suction gap S-2 formed along the line. In other words, a suction force (suction collecting force) for attracting the contaminated air G soaring from the heating cooker, cooking pan, etc. without taking it to the kitchen ceiling or the like is applied to the downward opening 6 of the hood body 1. It can be efficiently and intensively propagated.

FIG. 7 is a longitudinal side view showing another embodiment of the deep range hood provided with the airflow suppressing member according to the present embodiment.
As shown in FIG. 7, the deep range hood A-1 according to such an embodiment is basically the same as the deep range hood A of the above-described embodiment except for the configuration in which the longitudinal sectional shape of the rectifying plate 40 is changed. Therefore, the same components are denoted by the same reference numerals, and redundant description is omitted.
That is, the side view shape of the current plate 40 is formed as a flat surface as is well known, as shown in FIG. Then, the abutting portions 13c on both the left and right sides of the airflow suppressing member 13 are gradually inclined along the rectifying plate 4 disposed in front of the blower 2 in an obliquely downward posture by the support member 12 and the engagement / disengagement member 14 described above. Yes.

Although illustration is omitted, all the contaminated air G sucked and captured in the capture space M is drawn from the suction gap S-2 of the lower edge 4-2 of the rectifying plate 4 to the suction port 3 of the fan casing 2a. The suction gaps S-1 and S-3 on the three sides of the upper edge portion 4-1 and both side edge portions 4-3 of the current plate 4 except for the suction gap S-2 are closed so as to flow in the direction. By adopting the configuration, the suction force (suction collection force) for drawing the contaminated air G propagated to the downward opening 6 of the hood body 1 through the suction gap S-2 without escaping in the direction of the kitchen ceiling or the like. ) Can be more effectively propagated through the downward opening 6 of the hood body 1.
That is, instead of the airflow suppression member 13, the suction gaps S-1 at the three sides of the upper side edge part 4-1 and the side edge parts 4-3 excluding the lower side edge part 4-2 side of the rectifying plate 4 are provided. It is also conceivable to provide a gap closing member that closes S-3 between the current plate 4 and the front surface of the blower 2. However, as shown in FIGS. 1 and 7, the contaminated air G that rises from the heating cooker is sucked into the capture space M not only from the lower side of the hood portion 1a of the hood body 1 but also from the lower side of the front panel 1b. Since it is collected and flows in the direction of the upper side and both sides of the capture space M along the inner surface of the front panel 1b, the three edges of the upper edge part 4-1 and both edge parts 4-3 Therefore, the contaminated air G-2 needs to be sucked into the back side of the rectifying plate 4 without closing the suction gaps S-1 and S-3.

It is a vertical side view which shows the deep type range hood provided with the airflow suppression member which concerns on this embodiment. It is a cross-sectional top view of the same deep type range hood. It is a perspective view when a baffle plate is seen from the back side (blower side).
