A partition plate provided with a suction port of the exhaust means partitions the housing space forward and backward on the front side of the exhaust means;
The partition plate is inclined so that the upper front side is the front side.

  That is, since the housing space having at least the suction port of the exhaust means is partitioned back and forth by the partition plate provided with the suction port, the number of parts that come into contact with smoke or the like in the range hood is reduced. Moreover, since the partition plate is inclined so that the upper front side is the front side, even if it is provided at a high location above the cooking device, it is easy to reach the upper front side of the partition plate. Therefore, the cleanability of the range hood is improved.

Note that the front, rear, left, and right described in the claims are for convenience in order to show the relative positional relationship between the respective parts constituting the range hood.
The air containing smoke or the like means air containing a substance that is generated during cooking and is preferably discharged by a range hood. Smoke includes not only gas that is emitted when an object burns, but also mist and water vapor, etc., which appear to be dim, but smoke is merely an example. Of course, air containing steam, air containing mist-like oil droplets, and the like are also included in air containing smoke or the like.
The air containing smoke or the like collected in the open space may be a swirl flow or may not be swirl flow.
The rear guide plate may be provided on the rearmost side of the guide part, or a portion constituting the guide part may be provided on the rear side.
All of the exhaust means may be accommodated in the accommodation space, or a part other than the suction port may protrude outward from the accommodation space.
The hood body may be provided with a part such as an oil receiver.

  Although the said opening part may be provided in a side part, it may be provided in a rear part guide plate. The opening may be provided with an oil capturing filter. When an opening is provided in the side surface and a filter for capturing oil is provided in the opening, air containing smoke collected in the open space enters the front side of the accommodation space through the filter of the rear guide plate and sucks It is discharged from the mouth. Since air containing smoke or the like does not pass outside the left and right side portions, the passage route of air containing smoke or the like can be shortened inside the range hood, and the number of places where oil or the like is attached is reduced.

According to the invention which concerns on Claim 1, the cleanability of a range hood can be improved.
In the invention which concerns on Claim 2, the adhesion location of oil etc. can be decreased.

Although it is preferable to use a white light emitting diode as the light source 73 because the frequency of replacement of the light source can be reduced, a halogen lamp or the like may be used. The color of the light source 73 can also be other than white.

  In addition, the main parts of the hood body 10 and the main part of the range hood 1 such as the fan case 63 can be formed of a metal plate.

(2) Explanation of operation, action and effect of range hood:
Next, how the range hood 1 assembled as shown in FIGS. 1 to 3 discharges air containing smoke or the like will be described.
The air containing smoke, steam, mist-like oil droplets, etc. generated by cooking becomes an upward flow S1 and flows into the open space SP1, and is guided to the inner side surfaces 31a and 33a of the guide portion 30 to the left in FIG. It becomes the surrounding swirl flow S2. The rotation axis of the swirl flow S2 is directed left and right. Here, since the exhaust means 60 is sucking air from the openings 34, 34 provided on the left and right of the rear guide plate 33, as shown in FIG. Then, it passes through the filters 35, 35 and proceeds in the width direction D2 inside (exhaust direction S3 shown in FIG. 5) in the front space SP3 of the accommodation space. Air containing smoke or the like sucked from the suction port 51 is directed from the inside of the fan case 63 toward the exhaust pipe 64 (exhaust direction S4 shown in FIG. 2) and discharged to the outside.

  That is, since the accommodation space SP2 having the suction port 51 of the exhaust means 60 is partitioned back and forth by the partition plate 40 provided with the suction port 51, smoke or the like does not contact the rear space SP4 of the accommodation space. Thereby, the site | part which contacts smoke etc. inside a range hood decreases. Further, since there is no fan case or electrical box in the front space SP3 of the accommodation space, it is not necessary to clean a large uneven portion. Therefore, this range hood 1 has improved cleaning properties.

  Oil droplets and the like contained in the air flowing into the open space SP1 include an inner side surface 31a of the front guide plate, an inner side surface 33a and a rear surface of the rear guide plate 33, a front surface 40a of the partition plate 40 to which the bell mouth 50 is attached, and a fan 61. , Etc. The oil adhering to the portion of the accommodation space SP2 in the range hood 1 collects in the oil tray 13 as it flows down. Therefore, the oil in the oil tray 13 may be discarded from time to time, and if necessary, the filter 35 may be removed from the opening 34 and cleaned, and the oil adhering to the inner side surfaces 31a and 33a of the guide portion may be wiped off.

  Further, when cleaning the front space SP3 of the accommodation space, which is a passage for air containing smoke or the like, when the button 32 on the inner side surface 31a of the front guide plate is pressed, the front edge portion 33b of the rear guide plate is moved to the button 32. The latching part 36 is hooked on the protruding part 21. As a result, the rear guide plate 33 moves from the closed position L1 to the latching position L2, and the front space SP3 is slightly opened. Further, when the latching portion 36 is removed from the projecting portion 21, as shown in FIG. 4, the rear guide plate 33 is hooked on the rear guide plate hooking portion 48 to be in the open position L3, and the front space SP3 of the accommodation space is wide. Opened. If necessary, the rear portion of the rear guide plate 33 may be cleaned by removing the latch portion 33d from the rear guide plate hooking portion 48.

Here, with reference to FIG. 7, the effect | action and effect of this range hood 1 are demonstrated.
FIG. 7A is a vertical sectional view showing the range hood 1 in which the partition plate 40 is inclined so that the front upper side 40a1 is the front side, with the rear guide plate 33 removed. FIG. 7B is a vertical cross-sectional view showing the range hood of the comparative example in which the front surface of the partition plate is along the vertical plane PL2 with the rear guide plate removed. The inclined surface PL1 indicates a surface along the partition plate front surface 40a of the range hood 1.

  In the range hood of the comparative example shown in FIG. 7B, the partition plate front surface is provided along the vertical plane PL2, so that the partition plate is compared to the case of the inclined surface PL1 inclined so that the front upper side is the front side. The upper side of the front surface is a position retracted diagonally upward. Therefore, when the range hood is provided at a high position above the heating cooker as shown in FIG. 8, it is difficult to reach the upper side of the front side of the partition plate during cleaning, and it is not easy to clean the upper side of the front side of the partition plate.

  On the other hand, the range hood 1 shown in FIG. 7A is inclined so that the front upper side 40a1 of the partition plate is the front side, so that the partition plate is compared with the case where the partition plate front surface is provided along the vertical plane. The front upper side 40a1 is a position that has advanced forward and obliquely downward. Therefore, even if the range hood 1 is provided at a high place above the cooking device as shown in FIG. 1, it is easy to reach the front upper side 40a1 of the partition plate. Therefore, this range hood 1 has improved cleaning properties.

  When cleaning the fan 61, the bell mouth 50 is removed from the partition plate 40, and the fan 61 is taken out through the through hole 41 of the partition plate. After the cleaning is completed, the fan 61 is returned to the original position, the bell mouth 50 is attached to the partition plate 40, the rear guide plate 33 is hooked on the rear guide plate hooking portion 48, and the rear guide plate 33 is set to the closed position L1. The filter 33 may be attached to the opening 34 by hooking the portion 33 b to the button 32. Then, air containing smoke or the like can be discharged again by the range hood 1.

(3) Modification:
Various modifications can be considered for the present invention.
For example, in addition to the above-described fan assembly being housed in the housing space, a part of the fan assembly may protrude outward from the housing space, such as a fan motor going out of the housing space.
The rear guide plate and the front guide plate may be divided into two or more. Further, the front guide plate may have a shape deviated from the circular arc shape of the vertical cross section, such as a shape of a part of an elliptical circumference whose vertical cross section is deviated from the circle. The guide unit can generate a swirling flow even if a flap is not provided.
The opening for allowing air containing smoke or the like to pass from the open space to the accommodating space may be provided in the side panel 20 although it is preferably provided in the rear guide plate. Although the said opening part is suitable if it exists in both right and left, you may be made into only one. Moreover, although it is suitable if the air containing the smoke etc. which were collected in open space is made into a swirl flow, it does not need to be made a swirl flow.
The open space connected to the accommodation space via the opening may be divided into two or more.
The suction mouth of the bell mouth and the through hole of the partition plate may be non-circular such as an ellipse or a polygon in addition to the circular shape.

  In the embodiment described above, the partition plate is directly attached to the front surface of the fan case. However, the partition plate may be attached to the front surface of the fan case via another member such as a stay. Further, the partition plate only needs to be on the front side of the exhaust unit, and may be disposed on the front side of the fan case front surface with a space from the front surface of the fan case, in addition to being fixed in close contact with the front surface of the fan case. This interval is not particularly limited as long as the partition plate is provided with a suction port of the exhaust means, and air containing smoke or the like is introduced into the exhaust means by the bell mouth, so that diffusion to the rear space can be suppressed, for example, 5 to 20 mm. It can also be set to a degree.

  Note that the above-described basic functions and effects can be obtained even with a technique or the like that does not have the constituent requirements according to the dependent claims but includes only the constituent requirements according to the independent claims.

As described above, according to the present invention, a technique for improving the cleanability of the range hood can be provided according to various aspects.
In addition, the configurations disclosed in the embodiments and modifications described above are mutually replaced, the combinations are changed, the known technology, and the configurations disclosed in the embodiments and modifications described above are mutually connected. It is possible to implement a configuration in which replacement or combination is changed. The present invention includes these configurations and the like.
