Description

[Detailed description of the invention] Industrial application field This invention is a range hood that discharges oil smoke and waste gas generated in the kitchen installed above the stove to the outside, making cooking work especially comfortable on the stove. Regarding.

BACKGROUND ART Generally, when cooking on a stove, it is not possible to ensure sufficient illuminance for the work if there is only general lighting in the kitchen, and it sometimes becomes dark due to the shadow of the person cooking. Therefore, sufficient brightness can be secured with local lighting from the range hood lamp.
There was a demand for a range hood that would allow for comfortable cooking.

For this reason, conventional range hoods have a fan 10 as shown in FIGS. 6 and 7, for example.
A range hood main body 101 that stores 0 inside,
A decorative panel 102 that is locked to the front surface of the range hood main body 101 and forms a main suction port on the lower surface together with the range hood main body 101;
A front cover 108 has an opening window 104 formed toward the center of the stove 110, and a light bulb 107 is installed inside the front cover 108 so as to face the opening window 104 of the front cover 108. socket 106
and the opening window 1 to protect the light bulb 107.
04 and a lamp cover 109 having a certain degree of light transmittance.

Problems to be Solved by the Invention In the above-mentioned conventional configuration, the installation height of the range hood from the surface of the stove 110 is limited to a certain level for reasons of fire protection, and the rise in temperature of the range hood due to the heat of the light bulb 107 is reduced. Since the large-capacity light bulb 107 cannot be used for this reason, the lamp cover 1
Even if glass with good light transmittance was used as the material of 09, there was a limit to the illuminance on the stove 110.
In addition, since the light is diffused so that it irradiates almost the entire surface of the stove 110, there is a problem that it is not performed efficiently in terms of illuminance.

The present invention takes into account the above-mentioned conventional problems and aims to improve the comfort of cooking on a stove by providing efficient lighting.

Means for Solving the Problems In order to achieve the above object, the present invention includes a range hood main body that houses a fan therein and has an open bottom surface, and a range hood body that is integrally formed with the range hood main body and extends in a substantially horizontal direction. A partition plate that divides the inside of the hood body into the bottom opening side and the fan side, opening windows provided on the left and right sides of this partition plate, and covering each opening window, the cross-sectional shape is approximately semicircular when viewed from the front side. It has a cylindrical shape and a straight section that slopes diagonally toward the center of the range hood body.
two reflectors attached to the partition plate to form a space within the range hood body; and a light bulb fitted into a socket fixed to the reflector within the space formed by the reflector. The range hood consists of:

Effect With the above configuration, even if you use a light bulb with a capacity that does not cause problems due to the temperature of the range hood rising due to the heat from the light bulb, the overall illuminance will be increased by using two light bulbs, and the light will be reduced by the reflector. The light can be irradiated onto the stove surface without spilling onto other surfaces. Since the reflector has a semicircular cylindrical cross-sectional shape and a straight section that slopes diagonally toward the center of the range hood body, the light is efficiently irradiated onto the stove surface. The illuminance above will increase.

Embodiment An embodiment of the present invention will be described below based on FIGS. 1 to 5. In the figure, reference numeral 1 denotes a range hood body with a built-in fan 12, which is attached to a wall 11 above a stove 10. A decorative panel 2 is fixed to the front surface of the range hood main body 1, and together with the range hood main body 1, forms a main suction port on the lower surface.
Further, a partition plate 3 is horizontally provided integrally with the range hood main body 1, and the inside of the range hood main body 1 is partitioned into a main suction port side and a fan 12 side by this partition plate 3 and a filter 8. The partition plate 3 is provided with opening windows 4 at two places on the left and right, and two opening windows 4 are attached to the partition plate 3 so as to cover these opening windows 4 and form a space within the range hood main body 1. A reflecting plate 5 is provided. Each of the reflectors 5 has a substantially semicircular cylindrical cross-sectional shape when viewed from the front side, and has a straight line portion that is obliquely inclined toward the center of the range hood main body 1. The imaginary extension line intersects before reaching the 10th surface of the stove. A light bulb 7 is provided in the space formed by the reflector 5 and fitted into a socket 6 fixed to the reflector 5. and opening window 4
A transparent lamp cover 9 is provided to protect the light bulb 7.

In the above configuration, as shown in FIG. 2, the light from the two light bulbs 7 is irradiated onto the stove 10 without being leaked by the reflecting plate 5. The reflector 5 has a straight line part that is obliquely inclined toward the center of the range hood body 1, and the extension of this straight part has a shape that intersects until it reaches the top of the stove 10. The light of No. 7 can be efficiently concentrated on the surface of the stove 10, and especially on the central part. 3 to 5 show the relationship between the inclination of the straight line portion of the reflector 5 and the illuminance. By changing the slope θ of the straight line with respect to the vertical direction, the illuminance at four positions A, B, C, and D on the 10th surface of the stove is measured, and the relationship between the slope θ and the average value of the four-point illuminance is shown. The result is shown in Figure 5. When the tilt θ is about 30°, the average illuminance is the highest.

As described above, according to this embodiment, the illuminance on the stove 10 can be improved by lighting the range hood so that it is sufficient for cooking operations.

Effects of the invention As is clear from the explanation of the embodiments above, according to the present invention, the left and right sides of the partition plate in the range hood main body
Each of the opening windows provided in several locations is covered by two reflecting plates, each of which has a cylindrical cross-sectional shape that is approximately semicircular when viewed from the front, and has a straight portion that is obliquely inclined towards the center of the range hood body. , the illuminance on the stove surface can be increased to be sufficient for cooking by using only the illumination of the range hood, and the comfort of cooking can be improved.
