Definitions
- the present invention relates to a gas containing oily fumes generated when cooked in a cooking device such as a pan or a frying pan (including steam and exhaust gas in a gas range) through an exhaust duct. This is related to fans used in range hoods for discharging air outdoors. Background art
- the exhaust method using a range hood can be used in a so-called system kitchen because the range hood can guide gas containing oily smoke more efficiently than using a ventilation fan. is there. Moreover, if the range hood is placed close to the place where gas containing oily smoke is generated, the gas containing oily smoke can be reliably discharged, which is a highly advantageous exhaust method.
- the diameter of the exhaust duct must be guided to the wall or the ceiling and opened outside, it is very small compared to the open area of the range hood as described above.
- some measures must be taken.
- an exhaust device with a capacity of about 400 m 3 / h is sufficient if only exhaust gas is emitted, If you want to discharge too much, a capacity of about 50 O m 3 ,]! Is required.
- an exhaust device that can sufficiently discharge oil smoke is required, it must have a capacity of up to about 70 OmSZh. If the exhaust system with such a large capacity is used to exhaust air from an exhaust duct with a diameter of about 15 cm, the above-mentioned noise will inevitably be generated. For this reason, it is conceivable to use a so-called sirocco fan as a device with large displacement and low noise. Including the hood, it has a considerably large volume. If this is to be installed in a small-volume range hood or other parts, the design configuration of the entire range hood and system kit must be changed significantly. No.
- a ventilation box that is placed in the range hood or above and below to communicate with the exhaust duct and that is placed in the storage box that houses the exhaust duct, and that is connected to the exhaust duct; And a connecting box that is connected to the exhaust duct side and has a small diameter toward the exhaust duct, and a ventilation duct is provided substantially in the center of the ventilation box.
- this fan casing expands the contact area of the wind not only on the inner surface of casing 1 but also on the front and back sides of air guide 4 provided in casing 1.
- "Fan casing with improved efficiency in capturing oil and fat and without clogging can be provided at a low cost with a simple structure without processing the body and left and right plates.” (Description of paragraph 0 21)).
- the contact of the wind (gas containing oil smoke) not only with the inner surface of the casing 1 but also with the air guide 4 provided in the casing 1 is considered to be a cause of noise, and the aforementioned It is thought that the noise problem 1 cannot be solved.
- paragraph 0 0 1 1 of the above publication states that “the entrance edge 4 ′ of the air guide 4 is an inclined edge, a jagged edge, or the like so as to shift the timing of the wind collision at the time of inflow. Entrance edge 4a 'Prevents noise generation due to simultaneous collision over the entire length.'However, even if noise is prevented only at the entrance, it is only a part of the long air guide 4, It is considered that the noise control effect can hardly be expected. In addition, it is unlikely that a simple flow of gas containing oil smoke on the surface of the flat air guide 4 would be enough to collect or capture oil smoke, and the second problem of oil smoke was sufficiently solved. It is a technology that is unlikely to be considered. In addition, Patent Publication No.
- a “range hood” as shown in Fig. 13 has been proposed with the purpose of “providing”.
- an inner surface side of a fan casing accommodating a fan of a blower provided in the hood has an uneven surface.”
- the unevenness of the body portion alternates so as to cross the flow direction of the wind (gas containing oil smoke) caused by the rotation of the fan. It is formed continuously.
- the gas containing oil smoke sucked into the fan casing will collide with the above-mentioned uneven surface, and the oil smoke may be trapped by this.
- the conventional example shown in FIG. As described above, it is thought that noise is generated by the collision of the wind with the uneven surface. Therefore, the inventor of the present invention can take advantage of the exhaust method using the range hood, and at the same time, can reduce the generation of noise extremely, and how to effectively collect the oil smoke.
- the present invention was completed. That is, it is natural that the object of the present invention is to sufficiently collect the oil smoke that could not be collected by the general filter on the upstream side.
- An object of the present invention is to provide a fan 100 for a range hood which does not generate noise even when gas containing the gas flows. Disclosure of the invention

- the first filter 40 and the second filter 50 have a first groove 41 and a filter 230, respectively.
- the first groove 41 on the second filter 50 side is made larger than the first groove 41 on the first filter 40 side, whereby the first As shown in FIG. 0, each first groove 41 completely penetrates into the second groove 51 so that the first filter 40 and the second filter 50 form a portion where they contact each other. It is.
- the gas containing oil smoke flowing on or passing through the surfaces of the first filter 40 and the second filter 50 as described above naturally contacts or passes through the respective meshes of the first filter 40 and the second filter 50. Therefore, the oily smoke contained in the gas is liquefied and trapped by the first filter 40 or the second filter 50.
- the captured oil smoke is stored in the oil reservoir 21 provided at the bottom of the case main body 10 by the range hood fan 100 shown in the best mode described later. What is important is that when the gas containing oily smoke comes into contact with the surfaces of the first filter 40 and the second filter 50 or passes through these meshes, no loud noise is generated, and the range hood is not affected.
- the fan 100 is not a source of noise.

- the second filter 50 is in close contact with the first filter 40. For this reason, even if it receives the force of the gas containing oil smoke, neither the second filter 50 nor the first filter 40 vibrates and does not generate noise. Further, the second reason is described in more detail. Since each of the first filter 40 and the second filter 50 is a filter having a mesh, the flow of gas containing oily smoke is reduced by the first filter 40. It freely enters and exits the inside and the outside of the second filter 50 and the first filter 40 and the second filter 50 are sources of sound in the flow of gas containing oil smoke. Such a large resistance does not occur at all.
