Description

  The present invention relates to a range hood.

  A range hood is provided in the kitchen in order to discharge air containing smoke, steam, mist-like oil droplets, etc. generated during cooking to the outdoors. However, in order to suck in air containing mist-like oil droplets, it is inevitable that oil adheres to the range hood, and it is necessary to prevent the adhered oil from dripping from the range hood. Furthermore, in order to facilitate the cleaning of the range hood, it is necessary to prevent the adhered oil from diffusing into the corners or the like inside the range hood.

Techniques described in Patent Documents 1 and 2 are known as techniques for preventing oil dripping from a range hood. These techniques store oil adhering to the inside of the range hood at a predetermined location. In the technique described in Patent Document 1, a partition plate is arranged below the blower and the equipment in the hood (filter, filter bar, etc.) just before the blower, and the oil that flows down or drops from the blower and the equipment in the hood is this partition plate. The oil is dropped onto the oil pack (oil tray) from the discharge port formed in the partition plate. In the technique described in Patent Document 2, a filter is disposed substantially horizontally at the intake port of the range hood, and a recess of an oil receiver is provided around the filter so that oil flowing down along the inner surface of the range hood can be stored. .
JP 2000-74440 A Japanese Patent Laid-Open No. 10-306938

In the technique of Patent Document 1 described above, the overflow of oil from the oil pack is not considered. In the technique described in Patent Document 2, the oil that flows down or drops into the oil receiver is only the oil that adheres to the duct, and does not consider the oil that accumulates inside the blower (fan case).
An object of the present invention is to prevent dripping of oil overflowing from an oil tray that receives oil flowing out of a fan case into a range hood .

In order to solve the above problems, in the range hood of the present invention, a fan for sucking and discharging air, a fan case that houses the fan, and a filter that allows air sucked by the fan to pass through An oil tray that receives oil flowing out from the fan case, the oil tray being provided above the filter, and an oil guide plate that guides the oil onto the filter when the oil overflows from the oil tray Is attached to the fan case at any one of the front, rear, left and right attachment positions of the oil tray, and the oil guide plate extends obliquely downward from the attachment position to above the filter .
In this range hood, some of the mist-like oil droplets contained in the air sucked by the fan are collected by the filter, but the oil droplets not collected by the filter enter the inside of the range hood. Many of the oil droplets that have entered adhere to the inside of the fan case and aggregate, flow out of the fan case, and are stored in the oil tray. Since this oil tray is provided above the filter, even if oil overflows from the oil tray, it can be dropped or flowed down on the filter. Also, the oil overflowing from the oil tray falls on the oil guide plate and flows downward and is guided onto the filter.

As described above, according to the present invention, it is possible to prevent the oil overflowing from the oil tray that receives the oil flowing out from the fan case from dropping into the range hood .
According to the invention which concerns on Claim 2, it can prevent that the oil which spilled from the filter adheres to an electrical component.
According to the invention of claim 3, oil overflowing from the oil tray can be prevented from adhering to the electrical component.
According to the invention which concerns on Claim 4, the range hood which receives the oil which falls from a filter with a baffle plate can be provided .

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an external perspective view of a range hood. The range hood 100 includes a hood unit 10 and a blower unit 20. On the upper surface of the hood unit 10, an exterior member 30 is erected substantially vertically so as to shield the blower unit 20 from the outside. A range hood operation switch 17 is disposed on the front surface of the hood unit 10.

Next, each component of the range hood 100 is demonstrated with reference to FIG.2 and FIG.3. FIG. 2 is a perspective view of the range hood as viewed from obliquely below with the rectifying plate and the filter removed. FIG. 2 shows a state in which only one of the two filters is removed. FIG. 3 is a cross-sectional view of the range hood cut along the line AA in FIG.
The hood unit 10 includes a hood 11 serving as an exterior member and a guide plate 12 for introducing sucked air into the blower unit. The lower end opening portion of the hood unit 10 serves as an exhaust suction port 13. The hood 11 and the guide plate 12 are formed with openings for introducing air sucked from the exhaust suction port 13 into the blower unit 20.

A rectifying plate 14 is detachably attached to the guide plate 12, and a part of the exhaust suction port 13 is narrowed down. That is, by reducing the opening area of the exhaust suction port 13 and increasing the flow rate of air sucked by the range hood, it is possible to efficiently suck air containing smoke, steam, mist-like oil droplets, etc. generated during cooking. ing. In addition, illustration of the member which supports the baffle plate 14 to the guide plate 12 is abbreviate | omitted.
The rectifying plate 14 is formed wider than the filter 15 and is disposed so as to cover substantially the entire lower portion of the filter 15. Since the side end portion is in a tray shape bent upward, even if oil adhering to the filter 15 may drip from the filter 15, it accumulates on the rectifying plate 14 and dripping oil to the cooking table. Can prevent.
Further, a filter base 18 is provided at the opening of the guide plate 12, and a filter 15 is detachably attached to the filter base 18. In addition, a substrate storage section is defined behind the hood unit 10 to store a substrate 16 for operating the range hood. Furthermore, the gap between the hood 11 and the guide plate 12 is used as a wiring storage unit that stores wiring for connecting the electrical component and the operation switch 17. If oil flows into the electrical component storage section composed of the board storage section and the wiring storage section, it causes a malfunction.

  The blower unit 20 includes an exterior 21 of the blower unit 20, a fan 23, a motor 22 that rotationally drives the fan 23, a fan case 24 that houses the fan 23 therein, and a bell mouth for smoothly introducing air into the fan case 24. 25, an oil discharge port 24a provided at the front end of the lower surface of the fan case 24, an oil tray 26 attached to the lower surface of the fan case 24 so as to cover the oil discharge port 24a from below, and air sucked into the fan case 24 is exhausted A duct 27 serving as a passage is provided.

  The fan case 24 has a substantially cylindrical shape with a central axis directed in the front-rear direction, a suction port is provided in the front surface portion, and a motor 22 is attached to the rear surface portion. The fan 23 is a substantially cylindrical multi-blade fan (sirocco fan), and is accommodated in the fan case 24. The air that flows into the fan case 24 from the suction port by the fan 23 that is rotationally driven by the motor 22 is pushed toward the inner peripheral surface of the fan case 24 and reaches the duct 27 directly or along the inner peripheral surface. It is discharged from the duct 27. At this time, like a so-called centrifuge, centrifugal force is also applied to oil droplets in the air, and the oil droplets adhere to the inner peripheral surface of the fan case.

  An oil discharge port 24 a is formed at the lowermost end of the fan case 24 as a hole penetrating the inside and outside of the fan case 24. An oil tray 26 is attached to the fan case 24 so as to cover the oil discharge port 24a from the outside. The material of the oil tray 26 is not particularly limited. For example, a metal material such as stainless steel or aluminum is formed by pressing or the like, and the surface is appropriately subjected to rust-proofing or oil-repellent coating according to the characteristics of the metal material. Used.

Hereinafter, a structure for fixing the oil tray 26 to the fan case 24 will be described with reference to FIGS. 4 and 5. FIG. 4 is an oil tray perspective view of the present embodiment, and FIG. 5 is a partial cross-sectional view of the front of the fan case with the oil tray attached.
The oil tray 26 is formed as a substantially rectangular parallelepiped container having an open upper surface, and includes a container part 26a for storing oil, and a locking piece 26b that protrudes substantially horizontally outward from the upper ends of the left and right surfaces. The opening is attached to a tray mounting base 50 provided on the lower surface of the fan case 24 so that the opening faces the oil discharge port 24a on the lower surface of the fan case 24.

The tray mounting base 50 is formed with a fixing portion 50a fixed to the lower surface of the fan case 24, an mounting surface 50b to which the oil tray 26 is mounted, and an oil tray locking piece 26b formed below the mounting surface 50b. A cut and raised portion 50c sandwiched between the mounting surface 50b and an oil discharge port 50g is provided.
When the locking piece 26b of the oil tray is inserted into the gap between the mounting surface 50b and the cut-and-raised portion 50c, the locking piece 26b is sandwiched between the cut-and-raised portion 50c and the mounting surface 50b, and the oil tray 26 is placed in the fan case. 24 is detachably supported. The oil tray 26 attached in this manner is disposed above the filter 15 as shown in FIG. 3, and can be dropped or flowed down on the filter even if oil overflows from the oil tray.

Hereinafter, with reference to FIG. 6 and FIG. 7, the filter base 18 having an oil diffusion prevention structure that prevents oil from flowing into the electrical component storage unit will be described.
The filter base 18 shown in FIG. 6 has a substantially L-shaped cross section, and includes a fixing portion 18a fixed to the upper surface of the guide plate 12 and an upright piece 18b erected on the fixing portion. The height of the upright piece 18 b is set to a height that does not reach the inner surface of the hood 11. The filter 15 is placed on the fixed portion 18a, and is pressed and sandwiched between a leaf spring 18s attached to the inside of the upright piece 18b on the rear side of the range hood and the upright piece 18b on the front side of the range hood.

  In this way, the periphery of the filter 15 is surrounded by the upright piece 18b extending to a predetermined height, and even if the oil overflows and drops from the oil tray 26 and flows out around the filter 15, the upright piece 18b is dammed up. Inflow to the electrical component storage unit can be suppressed. Further, when the filter 15 is removed, the oil adhering to the filter 15 may flow down. Even in such a case, the oil is blocked by the standing piece 18b.

  The filter base 118 shown in FIG. 7 has a substantially U-shaped cross section, and includes a lower fixing portion 118a fixed to the upper surface of the guide plate 12, a standing portion 118b standing on the fixing portion, and a standing portion 118b. The upper fixing part 118 c is extended and fixed to the inner surface of the hood 11. The standing portion 118b shields a gap formed between the hood 11 and the guide plate 12 and isolates the electrical component storage portion from the oil path. The filter base 118 provided with this upright part 118b comprises a partition wall. The filter 15 is placed on the lower fixing portion 118a and is pressed and clamped between a leaf spring 18s attached to the inside of the standing portion 118b on the rear side of the range hood and a standing piece 18b on the front side of the range hood.

  Since the filter base 118 shields the gap between the hood 11 and the guide plate 12 in this way, even if the oil overflows and drip from the oil tray 26, the dropped oil is surely blocked by the filter base 118, and the electrical component is stored. Does not flow into the section. Further, when the filter 15 is removed, the oil adhered to the filter 15 may flow down. Even in such a case, the oil is blocked by the filter base 19.

Although the filter stand shown in FIG. 6 and FIG. 7 has the fixed part open end flush with the opening of the guide plate 12, it is not limited to flush. For example, there is a possibility that oil flows in through the gap between the filter base fixing portion 18a (or the lower fixing portion 118a) and the guide plate 12. To prevent this, the fixing portion open end is placed inside the opening of the guide plate 12. You may make it project to. Further, when the fixed portion 18a (or the lower fixed portion 118a) and the guide plate 12 are brought into close contact with each other, there is no need to consider oil inflow through the gap. It is good also as an opening part outer side.
The filter base is preferably formed of a metal material such as stainless steel or aluminum, and is screwed to the guide plate 12 or the hood 11 and fixed by welding.

  The positional relationship between the oil tray 26 and the filter 15 will be described with reference to FIG. In the above-described embodiment, the example in which the entire oil tray 26 is positioned directly above the filter 15 (A in FIG. 9) has been described. However, it is possible that a part of the oil tray is at a position off from directly above the filter 15 or the entire oil tray is off from directly above the filter 15 (for example, B and C in FIG. 9). In such a case, when part or all of the oil tray 26 is off from directly above the filter 15, an oil guide plate 28 that guides the oil overflowing from the oil tray 26 onto the filter 15 as shown in FIG. It is good to provide. Of course, in the present invention, the case where the filter 15 is located below the filter 15 as in D, E, and F in FIG. 9 is excluded.

In FIG. 8, the oil guide plate 28 is attached to the fan case 24 behind the oil tray 26. The oil guide plate 28 extends forward and obliquely downward from the mounting position, and the tip extends to the upper side of the filter 15 through the lower side of the oil tray 26. That is, the oil overflowing from the oil tray 26 drops on the oil guide plate 28, flows down to the tip of the oil guide plate 28, and drops onto the filter 15 from the tip of the oil guide plate 28. Also, is directed onto the filter 15 flows down the obstructed by the surface on the oil guide plate 28 in an oil well oil guide plate 28 running down the full Ankesu 24 lower surface rearward. The oil guide plate 28 is preferably formed of a metal material such as stainless steel or aluminum, and is screwed to the fan case 24 and fixed by welding.

The oil guide plate 28 may have a structure in which the left and right end portions are folded upward or grooves are provided on the oil guide plate 28 so that oil does not easily flow in the left-right direction. In this modification, the oil guide plate 28 is provided only on the rear side of the oil tray 26. However, the oil guide plate may be provided on the front side and the left and right sides of the oil tray 26. In addition, even when the oil tray 26 is located directly above the filter 15, an oil guide plate 28 may be provided in order to reliably drop the oil overflowing from the oil tray 26 onto the filter 15.
As described above, the oil guide plate 28 that guides the oil overflowing from the oil tray 26 onto the filter 15 constitutes an oil guide structure.

Hereinafter, the operation and effect of the range hood will be described.
Oil flowing out of the fan case 24 is accumulated in the oil tray 26. Even when the oil overflows from the oil tray 26, the overflowed oil falls on the filter 15 located below the oil tray 26, so that the oil overflowing from the oil tray 26 does not contaminate the inside of the range hood 100.
Moreover, since the current plate is provided under the filter, the oil falling from the filter is received by the current plate, and the oil does not drip from the range hood.

  In addition, the range hood 100 is provided with an electrical component storage section outside the filter 15 in the horizontal direction. A filter base 18 is disposed between the electrical component storage unit and the filter 15 mounting position to block an oil path leading from the filter 15 to the electrical component storage unit. As a result, even if oil overflows from the oil tray 26 or spills out of the filter 15 when the filter 15 is attached or detached, it can be prevented from being blocked by the filter base 18 and flowing into the electrical component storage unit. The filter base 18 may have a shape that completely blocks the gap.

  In addition, the oil guide plate 28 extends under the oil tray and diagonally forward and the front end thereof is located on the filter 15. Therefore, the oil overflowing from the oil tray 26 falls on the oil guide plate 28 and is guided to the filter 15 through the oil guide plate 28. That is, the oil overflowing from the oil tray 26 falls on the filter 15 more reliably.

  Note that the present invention is not limited to the above-described embodiments and modifications, and the structures disclosed in the above-described embodiments and modifications are mutually replaced, the combinations are changed, the known technique, and the above-described implementations. Configurations in which the configurations disclosed in the embodiments and modifications are mutually replaced or the combinations are changed are also included.
