The lower receiving member has an oil receiving box provided in a region directly below the hood so as to form an opening in a central portion of the lower end surface, and not projecting downward from the lower end surface in the opening. It is characterized by having.

  According to the configuration of the present invention, a smoke suction port is formed on the outer periphery of the lower portion of the hood by a simple overlapping structure of the upper cover member and the lower receiving member, and the smoke is guided to the upper portion of the hood through the inside. A range hood can be realized. Moreover, it is very simple structurally. In addition, by providing a smoke suction part on the outer peripheral side so as to surround the central part instead of the central part, the smoke received at the central part (non-suction part) is sucked at the outer peripheral side without being left behind and escaped to the outside. As a result, there is a certain level of smoke suction capability.

  The upper cover member and the lower receiving member in the present invention can be formed by bending a flat plate member. Thereby, since it is formed by simple bending of the plate material, the structure is very simple. In addition, a thin and simple structure consisting only of two plates overlapped, creating a new design.

  The upper cover member according to the present invention has an umbrella shape in which an end portion on the first side with respect to the center portion and an end portion on the opposite side are bent obliquely downward, and the lower receiving member has the umbrella shape. At least between the first diagonally lower edge of the upper cover member and the first edge of the lower end surface of the lower receiving member. A second side facing at least the lower side between the first side opening facing downward, the second side obliquely lower edge of the upper cover member and the second side edge of the lower end surface of the lower receiving member The opening may be configured as a smoke suction port of the smoke suction gap. According to this configuration, the shape is finished by a minimum bending process. Further, when the lower portion of the hood is viewed from the side of the side where the first side and the second side can be visually recognized at the same time, the first side and the second side end portions have a unique design of an upper constriction.

  In this case, the design is enhanced by making the first side and the second side symmetrical. In this case, the first and second smoke suction ports may be configured to face obliquely downward on the outer side, but may be opened so as to face diagonally below or on the inner side (center side). . In particular, if it is open so as to face directly below, that is, the end portions on the first side and the second side are bent obliquely downward on the outer side, and the edge on the first side and the second side of the upper cover member and the lower side If the first side and the second side edge of the lower end surface of the side receiving member are the same height, the hood lower part having the upper cover member and the lower receiving member becomes a substantially trapezoidal shape, an unprecedented design The range hood form can be realized.

  The lower receiving member according to the present invention has a saucer shape in which an end portion on the first side with respect to the center portion and an end portion on the opposite side are bent obliquely upward and outward, and the upper cover member includes the saucer. The lower receiving member having a shape is disposed so as to cover the upper side, and the first side obliquely upper edge of the lower receiving member and the first side edge of the upper end surface of the upper cover member A first side opening facing the lower side of the first side, a second side diagonally upper edge of the lower receiving member and a second side edge of the lower end surface of the upper cover member. Both of the openings facing diagonally below the two sides can be configured as smoke suction ports of the smoke suction gap. According to this configuration, the shape is finished by a minimum bending process, which is advantageous in terms of cost. Further, when the lower portion of the hood is viewed from the side of the side where the first side and the second side can be visually recognized at the same time, the first side and the second side end portion have a unique design of a constriction.

  In this case as well, the design is increased by making the first side and the second side symmetrical. Also, in this case, the lower surface of the lower receiving member, which forms the first and second end portions, is bent obliquely upward and outward, and the lower surface is a slope that guides smoke to the smoke suction port located above the lower receiving member. Because of its shape, it has high smoke suction. Further, the lower portion of the hood having the upper cover member and the lower receiving member if the respective edges of the first side and the second side of the upper cover member are located at the tip of the lower surface forming the slope shape. Has a substantially inverted trapezoidal shape and can realize an unprecedented range hood form.

  In the present invention, a first extending direction connecting the first side and the second side according to claim 3, comprising the requirements according to claim 3 and claim 4, and the first side according to claim 4. And a second extending direction connecting the second side and the second side can be set to be orthogonal. Thus, when the first side and the second side according to claim 4 are defined as the third side and the fourth side, respectively, in the side view from both the first side and the second side of the hood lower part. Thus, a range hood having an unconventional form of having an inverted trapezoidal outer edge shape in a side view from both the third side and the fourth side can be realized.

  In addition, by making the upper cover member a metallic color and the lower receiving member black, the impression of the lower receiving member is erased, and the thinness of the upper cover member at the bottom of the hood is further emphasized, and the design is excellent It will be. In addition, since the black paint is realized by the oil repellent paint, the oil is easily removed and the cleaning property is excellent.

  The lower receiving member according to the present invention can be formed by forming an opening in the center portion of the lower end surface and having an illumination portion provided in the opening so as not to protrude downward from the lower end surface. Since the lower surface of the central portion of the lower receiving member formed of a flat plate member is a flat surface, the design is not impaired by disposing the illuminating portion so as not to protrude from the lower surface. Moreover, the illumination part in this invention is formed separately from the lower receiving member, and is integrally fixed to the upper cover member. For this reason, when removing the lower receiving member in order to clean the inside of the lower portion of the hood, the illumination unit remains on the upper cover member side, so the lower receiving member can be easily removed. Cleaning becomes easy.

  In the lower receiving member in the present invention, in the form of forming an opening in the center part of the lower end surface, in the form of non-projecting downward from the lower end surface in the opening, provided in the region directly below the upper portion of the hood, It can be formed with an oil receiving box that can be attached and detached from below. Since the lower surface of the central portion of the lower receiving member formed of a flat plate member is a flat surface, the oil receiving box is disposed so as not to protrude from the lower surface, so that the design is not impaired.

  In consideration of the accuracy of assembly and the like, in the present invention, the unevenness of ± 1 mm with respect to the reference surface is determined to be flat and non-projecting with respect to the reference surface.

  Here, FIG.1 and FIG.2 is the system kitchen 300 provided with the kitchen stand 200 provided with the water washing 202 and the heating apparatus 203, and the smoke hood 100 mentioned above.

  The kitchen table includes an integral support structure 210 having a support portion 205 that extends linearly upward from above the floor surface 402 and a top plate portion 201 that is formed so as to spread horizontally above the support portion 205. The support structure 210 is formed in a substantially T shape when viewed from the first side and the second side (that is, in the left and right side view). As for the top plate portion 201, since the first side end surface (front surface) and the second side end surface (back surface) are formed as slopes inclined from the upper outer side toward the lower inner side, they are viewed from the first side and the second side. (Ie, in a left and right side view), it looks like an inverted trapezoid. This is the same for the lower hood 34 of the smoke hood 100, and it looks like an inverted trapezoid. In addition, the storage part 204 of the kitchen table 200 is attached to an upper position that is not in contact with the floor surface 402 on the front side of the support structure 210.

  Although one embodiment of the present invention has been described above, this is merely an example, and the present invention is not limited to this, and the knowledge of those skilled in the art can be used without departing from the spirit of the claims. Various modifications based on this are possible. Hereinafter, an embodiment different from the above embodiment will be described.

  In the above embodiment, when viewed from the first side and the second side, it looks like the inverted trapezoidal shape as described above, and when viewed from the third side and the fourth side, it looks like the trapezoidal shape as described above, However, it is also possible to configure the third side and the fourth side in the same manner as the first side and the second side so that the first side to the fourth side all look like an inverted trapezoidal shape. On the contrary, you may comprise the 1st side and the 2nd side similarly to the 3rd side and the 4th side so that it may look like a trapezoid in all the 1st side-the 4th side.
