[0008] As mentioned above, in conventional cooking exhaust devices, in order to exhaust air containing more oily smoke or odors, it was necessary to increase the exhaust volume of the cooking exhaust device. However, increasing the exhaust volume of the cooking exhaust device may result in negative pressure in the room or a decrease in noise level. Therefore, the present invention aims to exhaust more oily smoke or odor-containing air without increasing the total amount of exhaust air by improving the collection efficiency of air containing oily smoke or odors without increasing the amount of exhaust air outdoors. Note that the collection efficiency here is an index that indicates the proportion of air containing oily smoke or odors relative to the total amount of exhaust air. For example, when the total amount of exhaust air is 500 m 3 / h, of which 300m3 of air contains oily smoke or odors 3 / h, the collection efficiency is 60%. Oil smoke refers to steam that is a mixture of water vapor and oil produced during cooking.

[0009] Hereinafter, embodiments will be described with reference to the drawings. Note that the following embodiments show examples of cooking exhaust devices according to the present invention. The numerical values, shapes, materials, components, and positional relationships of the components shown in the embodiments are merely examples and are not intended to limit the scope of the claims. Furthermore, terms indicating relationships between elements, such as perpendicular and parallel, do not only indicate the strict meaning, but also include a range of substantial equivalence, for example, a difference of a few percent. Furthermore, each figure is not necessarily an exact illustration. In each figure, substantially identical components are assigned the same reference numerals, and duplicate explanations may be omitted or simplified.

[0010] The x, y, and z axes shown in the figures are for the convenience of explaining the positional relationships of the components. Unless otherwise specified, the direction indicated by the z-axis arrow points vertically upward. The xy plane is a horizontal plane, which is common to all figures. The direction indicated by the x, y, and z axes is the positive direction of each x, y, and z axis, and the opposite direction is the negative direction. (Embodiment 1) FIG. 1 is an external perspective view of a cooking exhaust device 1 and cooking equipment 2 according to a first embodiment. As shown in FIG. 1, the cooking exhaust device 1 is used in combination with the cooking equipment 2. The cooking exhaust device 1 and cooking equipment 2 are installed together facing the living room or dining room, creating a so-called face-to-face kitchen. Face-to-face kitchens include island kitchens and peninsula kitchens. For ease of explanation, the drawings in the first embodiment show a gap between the cooking exhaust device 1 and cooking equipment 2. In other words, the cooking exhaust device 1 and cooking equipment 2 are positioned adjacent to each other. Note that "adjacent" includes both cases where the cooking exhaust device 1 and cooking equipment 2 are placed in contact with each other and cases where there is a small gap between the cooking exhaust device 1 and cooking equipment 2.

[0011] Cooking exhaust device 1 is a type of ventilation device that exhausts air containing oily smoke or odors generated during cooking to the outdoors. Cooking exhaust device 1 captures air containing oily smoke and odors generated from cooking appliances 23a, 23b provided on top surface 21 of cooking equipment 2, as well as the air surrounding cooking appliances 23a, 23b, and exhausts it from indoors to outdoors. Strictly speaking, cooking exhaust device 1 does not exhaust all of the air it draws in, but rather blows at least a portion of the air indoors, but this will be described in more detail below.

[0012] The cooking exhaust device 1 includes a housing 10 and a rear wall 60.

[0013] The housing 10 is a hollow, approximately rectangular parallelepiped. The interior of the housing 10 is in communication with the interior of the rear wall 60 (see FIG. 4, etc.). The housing 10 has a front surface 12, a right side surface 13, a rear surface 14, a left side surface 15, a bottom surface 16, and a housing top surface 11.

[0014] The front surface 12 is one surface on the front side (negative side of the y-axis) of the housing 10, and faces the rear surface 14 across the inside of the housing 10. The front surface 12 is one surface that is adjacent to the rear side surface 27 of the cooking equipment 2.

[0015] The right side surface 13 is one surface on the right side (positive side of the x-axis) of the housing 10, and faces the left side surface 15 across the inside of the housing 10. If the facing kitchen is an island kitchen, the right side surface 13 is the surface that does not contact the wall of the house. If the facing kitchen is a peninsula kitchen, either the left side surface 15 or the right side surface 13 is the surface that contacts the wall of the house.

[0016] The rear surface 14 is one surface on the rear side (positive side of the y-axis) of the housing 10, and faces the front surface 12 across the inside of the housing 10.

[0017] The left side surface 15 is a surface on the left side (negative side of the x-axis) of the housing 10, and faces the right side surface 13 across the interior of the housing 10. If the counter-style kitchen is an island kitchen, the left side surface 15 is a surface that does not contact the wall of the house. If the counter-style kitchen is a peninsula kitchen, either the left side surface 15 or the right side surface 13 is a surface that contacts the wall of the house.

[0018] The bottom surface 16 is one surface on the lower side (negative side of the z-axis) of the housing 10, and faces the housing top surface 11 via the inside of the housing 10. The bottom surface 16 is the surface that comes into contact with the floor surface of the house.

[0019] Housing top surface 11 is one surface on the upper side (positive side of the z-axis) of housing 10, and faces bottom surface 16 across the inside of housing 10. Housing top surface 11 is provided with second air inlet 40.

[0020] The second air inlet 40 is an opening provided in the upper surface 11 of the housing. In other words, the second air inlet 40 is provided below the first air inlet 30. As will be described in detail later, the second air inlet 40 is provided on the rear side of the top surface 21. Furthermore, the second air inlet 40 is an opening that draws in air located relatively lower in the space above the top surface 21 of the cooking appliance 2, and blows it out through the air outlet 50 via the inside of the housing 10. The detailed configuration of the second air inlet 40 will be described later.

[0021] The rear wall 60 is a hollow structure that stands vertically upward (toward the positive side of the z-axis) from the upper surface 11 of the housing. The rear wall 60 is located on the rear side of the cooking appliance 2. In other words, the rear wall 60 is located on the rear side of the second air inlet 40. The interior of the rear wall 60 communicates with the interior of the housing 10 (see FIG. 5). The rear wall 60 has a front surface 61.

[0022] The front surface 61 is one surface on the front side (cooker side) of the rear wall 60. The front surface 61 is a surface that is approximately perpendicular to the housing top surface 11. The front surface 61 includes the first air inlet 30 and the air outlet 50.

[0023] The first air inlet 30 is an opening provided on the front surface 61, and connects the inside of the rear wall 60 to the outside through this opening. As will be described in detail later, the first air inlet 30 is an opening for drawing in air from a relatively higher position in the space above the top surface 21 of the cooking appliance 2 and discharging it outdoors. The detailed configuration of the first air inlet 30 will be described later.

[0024] The air outlets 50 are openings provided on both ends of the first air inlet 30 in the x-axis direction, and blow out the air drawn in from the second air inlet 40. In other words, the air outlets 50 are provided on both sides of the first air inlet 30. The air outlet 50 includes an air outlet angle setting unit 51 that sets the direction in which the air is blown out, which will be described later together with the detailed configuration of the air outlet 50.

[0025] The cooking equipment 2 is used by a cook to mainly cook food. The cooking equipment 2 has, for example, a substantially rectangular parallelepiped shape. The cooking equipment 2 has a top surface 21, a bottom surface 22, a front side surface 24, a right side surface 26, a rear side surface 27, and a left side surface 28.

[0026] Top surface 21 is the surface that corresponds to the upper end of cooking equipment 2, and in this embodiment, is provided at the same height as housing upper surface 11. Top surface 21 has a substantially rectangular shape when viewed from above (as viewed from the direction of arrow T in FIG. 1 ), and top surface 21 faces bottom surface 22. Top surface 21 is a surface that is substantially perpendicular to front side surface 24, right side surface 26, rear side surface 27, and left side surface 28. Top surface 21 is provided with cooking devices 23a and 23b.

[0027] Cooking appliances 23a and 23b are components that heat cooking utensils, such as pots, placed on them. Cooking appliances 23a and 23b may be gas stoves, electric cookers, or induction cookers. More specifically, cooking appliances 23a and 23b are arranged in a typical two-burner configuration. For example, cooking appliances 23a and 23b are each arranged along the x-axis direction, with cooking appliance 23a being arranged on the negative side of the x-axis and cooking appliance 23b being arranged on the positive side of the x-axis. Cooking appliances 23a and 23b are, for example, typical two-burner stoves equipped with two heating elements, but may also be typical one-burner or three-burner stoves equipped with one or three heating elements.

[0028] The bottom surface 22 is a surface that corresponds to the lower end of the cooking equipment 2 and is a surface that faces the top surface 21. The bottom surface 22 is also a surface that comes into contact with the floor surface of the house.

[0029] The front side surface 24 is one of the front surfaces of the cooking equipment 2, and faces the rear side surface 27 across the interior of the cooking equipment 2. A cook stands closer to the front side surface 24 when using the cooking equipment 2. In other words, a cook stands on the front side surface 24 side when using the cooking equipment 2. The front side surface 24 is provided with doors 25a and 25b.

[0030] Door 25a is provided on the left side surface 28 side of front side surface 24. Door 25a opens and closes by rotating around the axis of the boundary line between door 25a and left side surface 28. When door 25a is opened, it connects storage section 29 with the outside of cooking appliance 2.

[0031] Door 25b is provided on the right side surface 26 side of front side surface 24. Door 25b opens and closes by rotating around the axis of the boundary line between door 25b and right side surface 26. When door 25b is opened, it connects storage section 29 with the outside of cooking appliance 2.

[0032] The storage section 29 is a part of the internal space of the cooking equipment 2, and is a space capable of storing, for example, cooking utensils.

[0033] The right side surface 26 is the surface that faces the left side surface 28 across the interior of the cooking equipment 2. Specifically, if the counter-style kitchen is an island kitchen, the right side surface 26 is the surface that does not contact the wall of the house. If the counter-style kitchen is a peninsula kitchen, either the left side surface 28 or the right side surface 26 is the surface that contacts the wall of the house.

[0034] The left side surface 28 is a surface that faces the right side surface 26 across the interior of the cooking appliance 2. If the kitchen is an island kitchen, the left side 28 is the side that does not contact the wall of the house. If the kitchen is a peninsula kitchen, either the left side 28 or the right side 26 is the side that contacts the wall of the house.

[0035] Next, the detailed configuration of the second air inlet 40 will be described with reference to Figure 2. Figure 2 is a top view of the cooking exhaust device 1 and cooking equipment 2 as seen from above in Figure 1 (as seen from the direction of arrow T in Figure 1).

[0036] The second suction port 40 has a substantially rectangular shape in a top view. The second suction port 40 is provided with a predetermined distance D1 between the rear end (one side) of the second suction port 40 and the front surface 61 of the rear wall 60. The predetermined distance D1 is, for example, approximately 10 mm to 50 mm. The second suction port 40 is provided with a predetermined distance D3 between the front end (one side) of the second suction port 40 and the front surface 12 of the housing 10. The predetermined distance D3 is, for example, approximately 10 mm to 50 mm. The length D2 of the second suction port 40 in the y-axis direction is, for example, approximately 10 mm to 50 mm. The width W1 of the second suction port 40 in the x-axis direction is, for example, approximately 450 mm to 600 mm. In other words, both ends of the second suction port 40 in the x-axis direction are provided outside the cooking exhaust device 1 relative to the cooking appliances 23a and 23b. In other words, in the x-axis direction, the left end of second suction port 40 is provided to the left of cooking devices 23a, 23b, and the right end of second suction port 40 is provided to the right of cooking devices 23a, 23b. Second suction port 40 is provided with a predetermined distance D4 between the center of second suction port 40 in the y-axis direction and the centers of cooking devices 23a, 23b in the y-axis direction.

[0037] Furthermore, in the present embodiment, second suction port 40 has a generally rectangular shape with its elongated dimension in the x-axis direction, but there are no particular limitations on the opening shape, number of openings, arrangement, etc. of second suction port 40. For example, multiple circular openings may be arranged side by side in any direction (for example, the x-axis direction or the y-axis direction), or multiple polygonal openings may be arranged side by side in any direction (for example, the x-axis direction or the y-axis direction).

[0038] The second air inlet 40 draws in air that is located relatively lower in the space above the top surface 21 of the cooking equipment 2, and blows it out through the air outlet 50 via the inside of the housing 10, as will be described later together with an explanation of the air flow that flows through the second air inlet 40.

[0039] Next, the detailed configuration of the air outlet 50 and the air outlet angle setting unit 51 will be described with reference to Figures 3 and 4. Figure 3 is an enlarged view of the area around the air outlet 50 in Figure 2. Figure 4 is a front view of the cooking exhaust device 1 and cooking equipment 2 as seen from the front of Figure 1 (as seen from the direction of arrow S in Figure 1).

[0040] As shown in FIG. 4, the air outlet 50 is a substantially rectangular opening provided on the front surface 61 of the rear wall 60, and blows out the air drawn in from the second air inlet 40 indoors. The height H1 of the air outlet 50 in the vertical direction (z-axis direction) is, for example, about 200 mm to 300 mm. In this embodiment, the upper end of the air outlet 50 is spaced a predetermined distance H2 from the upper end of the front surface 61. The predetermined distance H2 is, for example, about 1 mm to 50 mm. From the viewpoint of improving collection efficiency, it is preferable that the upper end of the air outlet 50 be located at a height approximately the same as the upper end of the first air inlet 30 in the vertical direction (z-axis direction) or above the first air inlet 30. In this embodiment, the air outlet 50 is located so that the upper end of the air outlet 50 is at the same height as the upper end of the first air inlet 30. In addition, the lower end of the air outlet 50 is spaced a predetermined distance H3 from the housing upper surface 11. The predetermined distance H3 is, for example, about 0 mm to 25 mm. In other words, when the cooking utensil 5 is placed on the cooking appliance 23a, 23b (see FIG. 5), the lower end of the air outlet 50 is preferably located below the top part 6 of the cooking utensil 5. The width W2 of the air outlet 50 in the x-axis direction is, for example, about 20 mm to 50 mm. The mouth 50 is configured to have an air outlet 50a and an air outlet 50b.

[0041] 3, the right end La of the air outlet 50a is located to the left (negative side of the x-axis) of the left edge of the second air inlet 40. In other words, the air outlet 50a is located outside (on the left side of) the cooking exhaust device 1 with respect to the second air inlet 40.

[0042] Furthermore, the left end Lb of the air outlet 50b is located to the right (positive side of the x-axis) of one side of the right end of the second air inlet 40 in the x-axis direction. In other words, the air outlet 50b is located outside (to the right) the cooking exhaust apparatus 1 with respect to the second air inlet 40. In other words, the air outlet 50 is located outside the cooking exhaust apparatus 1 with respect to the second air inlet 40 in the x-axis direction. In other words, the air outlet 50 is configured to prevent the air blown out from the air outlet 50 from being directly sucked into the second air inlet 40.

[0043] The blowing angle setting unit 51 is a plate-like member provided to adjust the blowing angle of the air blown out from the air outlet 50. As shown in Fig. 4, the vertical height of the blowing angle setting unit 51 is approximately the same as the vertical height H1 (z-axis direction) of the air outlet 50. The blowing angle setting unit 51 is configured to include a blowing angle setting unit 51a and a blowing angle setting unit 51b.

[0044] As shown in FIG. 3, the air outlet angle setting unit 51a is provided so as to incline to the right as it moves from the air outlet 50a toward the rear surface 14. Specifically, the air outlet angle setting unit 51a is provided so that the angle θ1 formed between the plate surface 52 of the air outlet angle setting unit 51a and the left side surface 15 (or left side surface 28) is approximately 45°. In other words, the angle θ2 formed between the traveling direction of the air blown out from the air outlet 50a (the direction of arrow A) and an imaginary extension line P of the left side surface 28 is also approximately 45°. In other words, the air outlet 50a blows air toward the front side (the cook's side) of the air outlet 50a and toward the left side (outside) of the cooking equipment 2 by the air outlet angle setting unit 51a. Furthermore, θ1 and θ2 do not necessarily have to be 45° and may be, for example, approximately 30° to 60°.

[0045] The imaginary extension line P is an imaginary straight line extending in the positive direction of the y-axis from the left side surface 28 of the cooking equipment 2. In other words, the imaginary extension line P can be said to be a line along the y-axis direction.

[0046] As shown in FIG. 3, the air outlet angle setting unit 51b is provided so as to incline leftward from the air outlet 50b toward the rear surface 14. Specifically, the air outlet angle setting unit 51b is provided so that the angle θ3 formed between the plate surface 53 of the air outlet angle setting unit 51b and the right side surface 13 (or right side surface 26) is approximately 45°. As a result, the angle θ4 formed between the traveling direction of the air blown out from the air outlet 50b (the direction of arrow B) and an imaginary extension line Q of the right side surface 26 is also approximately 45°. In other words, the air outlet 50b blows air toward the front side of the air outlet 50b (the cook's side) and toward the right side (outside) of the cooking equipment 2 by the air outlet angle setting unit 51b. Note that θ3 and θ4 do not necessarily have to be 45° and may be, for example, approximately 30° to 60°.

[0047] The imaginary extension line Q is a line extending in the positive direction of the y-axis from the right side surface 26 of the cooking equipment 2. In other words, the imaginary extension line Q can be said to be a line along the y-axis direction.

[0048] Next, the detailed configuration of the first air inlet 30 will be described with reference to FIG.

[0049] The first suction port 30 is an opening provided on the front surface 61 of the rear wall 60. In other words, the first suction port 30 is provided above the second suction port 40. The first suction port 30 is provided on the front surface 61 of the rear wall 60. The first suction port 30 communicates between the inside and the outside. The first suction port 30 is a so-called slit-shaped opening in which the width W3 in the x-axis direction is longer than the height H6 in the vertical direction (z-axis direction). In other words, the first suction port 30 is a slit having a longitudinal direction in the horizontal direction. The height H6 in the vertical direction (z-axis direction) of the first suction port 30 is, for example, approximately 10 mm to 50 mm. The width W3 in the x-axis direction of the first suction port 30 is, for example, approximately 450 mm to 600 mm. In other words, the width W3 of the first suction port 30 is approximately the same as the width W1 of the second suction port 40. More specifically, the width W3 of the first suction port 30 is preferably the same as or narrower than the width W1 of the second suction port 40. In this embodiment, the width W3 of the first suction port 30 and the width W1 of the second suction port 40 are assumed to be the same length. Four first air inlets 30 are arranged in the vertical direction. In other words, the multiple first air inlets 30 are arranged in the vertical direction (z-axis direction) at a predetermined interval H5. The predetermined interval H5 is, for example, approximately 10 mm to 100 mm. The first air inlets 30 are spaced apart from the air outlet 50 in the x-axis direction by a predetermined interval W4. The predetermined interval W4 is, for example, approximately 10 mm to 40 mm. The first air inlets 30 are arranged at a predetermined interval H4 from the housing top surface 11. The predetermined interval H4 is, for example, approximately 90 mm to 110 mm. The opening shape, number, and arrangement of the first air inlets 30 are not particularly limited. For example, multiple circular openings may be arranged in the x-axis direction, or multiple openings of other polygonal shapes may be arranged in the x-axis direction.

[0050] The first air inlet 30 draws in air from a relatively higher position in the space above the top surface 21 of the cooking equipment 2 and exhausts it outdoors, and the flow of air drawn in from the first air inlet 30 will be described in detail later.

[0051] Next, exhaust fan 35 and circulation fan 45 will be described with reference to Figures 5 and 6. Figure 5 is a cross-sectional side view of cooking exhaust device 1 and cooking equipment 2 taken along the line III-III in Figure 2. Figure 6 is a cross-sectional side view of cooking exhaust device 1 and cooking equipment 2 taken along the line IV-IV in Figure 2.

[0052] The cooking exhaust device 1 includes an exhaust fan 35 and a circulation fan 45.

[0053] As shown in FIG. 5, the exhaust fan 35 is provided in an air passage connecting the first air inlet 30 and the outdoor OT. In other words, the exhaust fan 35 is provided inside the housing 10. The exhaust fan 35 is a so-called fan that generates an airflow by rotating a fan. The exhaust fan 35 generates an airflow in a direction from the first air inlet 30 toward the outdoor OT. The airflow volume of the exhaust fan 35 is, for example, 250 m 3 / h~350m 3 The air volume of the exhaust fan 35 is preferably set to be larger than the air volume of the circulation fan 45.

[0054] As shown in FIG. 6, the circulation fan 45 is provided in an air passage connecting the second air inlet 40 and the air outlet 50. In other words, the circulation fan 45 is provided inside the housing 10. The circulation fan 45 is a so-called fan that generates an airflow by rotating a fan. The circulation fan 45 generates an airflow in a direction from the second air inlet 40 toward the air outlet 50. The airflow volume of the circulation fan 45 is, for example, 150 m 3 / h~250m 3 In other words, the air flow rate of the circulation fan 45 is preferably set to be smaller than the air flow rate of the exhaust fan 35.

[0055] Next, the flow of air drawn in through the first air inlet 30 and the second air inlet 40 will be described with reference to FIGS.

[0056] Cooking utensil 5 is, for example, a pot or a frying pan that can be placed on cooking appliances 23a and 23b to perform cooking.

[0057] The top part 6 is the top end of the cooking utensil 5. In other words, the top part 6 is the top end of the cooking utensil 5 such as a frying pan. The top portion 6 is an opening (not shown) that the appliance has. In other words, the top portion 6 is an opening through which air containing oily smoke or odors emitted from the cooking appliance 5 is released from the cooking appliance 5.

[0058] Here, the space above the cooking equipment 2 is divided into and defined as a first space 80 located vertically above the top 6 (upper end) of the cooking utensil 5, and a second space 90 located below the top 6 (upper end) of the cooking utensil 5. In other words, in the first space 80, first air EA is drawn into the first suction port 30, as indicated by the black arrow in FIG. 5. In the second space 90, second air RA is drawn into the second suction port 40, as indicated by the white arrow in FIG. 6. In yet other words, when the cooking utensil 5 is placed in the cooking appliances 23a and 23b, the first suction port 30 is located above the top 6 of the cooking utensil 5. In addition, when the cooking utensil 5 is placed in the cooking appliances 23a and 23b, the second suction port 40 is located below the top 6 of the cooking utensil 5. The height of the cooking utensil 5 varies depending on the type of cooking utensil 5. Cooking utensil 5 in the present embodiment is divided into first space 80 and second space 90 based on a pot of general height (for example, about 100 mm in height) among cooking utensils.

[0059] The first space 80 is a relatively upper space within the upper space, which is a space located above the cooking equipment 2.

[0060] The second space 90 is a relatively lower space in the upper space, which is a space located above the cooking equipment 2.

[0061] The first air EA is air within the first space 80. The first air EA contains more oily smoke or odors generated by cooking than the second air RA. In other words, the first air EA is air above the top 6 of the cooking appliance 5 when the cooking appliance 5 is set in the cooking devices 23a and 23b.

[0062] The second air RA is air within the second space 90. The second air RA contains less oily smoke or odors caused by cooking than the first air EA. In other words, the second air RA is cleaner than the first air EA. In other words, the second air RA is air below the top 6 of the cooking appliance 5 when the cooking appliance 5 is set in the cooking devices 23a and 23b.

[0063] Assume that a user places cooking implement 5 in cooking appliance 23a, 23b, for example, and starts cooking, and cooking exhaust device 1 starts operating. That is, exhaust fan 35 and circulation fan 45 start blowing air. As a result, as shown in FIG. 5, first air EA in first space 80 is sucked in through first air inlet 30, passes through the interior of rear wall 60 and the interior of housing 10, and is exhausted to the outdoor OT. Meanwhile, as shown in FIG. 6, second air RA is sucked in through second air inlet 40 located below first air inlet 30, passes through the interior of housing 10 and the interior of rear wall 60, and is blown out from air outlet 50 toward the cook.

[0064] With this configuration, the second air inlet 40 draws in the relatively clean second air RA. Furthermore, the air outlet 50 blows the second air RA into the room, circulating the second air RA within the room. This prevents the second air RA from being drawn in through the first air inlet 30 and being exhausted to the outdoor OT, and efficiently exhausts the first air EA containing a large amount of oily smoke or odor to the outdoor OT. In other words, the first air inlet 30 draws in the relatively clean second air RA and prevents it from being exhausted to the outdoor OT. In other words, air is prevented from flowing into the first space 80 from below and the sides of the first space 80, and the first air inlet 30 efficiently draws in the first air EA. As a result, the proportion of air containing oily smoke or odor in the exhaust air can be increased, which means improved collection efficiency. is possible.

[0065] The second air inlet 40 is provided on the housing upper surface 11. In other words, the second air inlet 40 is provided at a position far below the first air EA.

[0066] With this configuration, the second air inlet 40 is prevented from drawing in the first air EA. In other words, the second air inlet 40 more reliably draws in the second air RA. That is, the second air RA is prevented from being drawn into the first air inlet 30. As a result, the proportion of the first air EA in the air drawn into the first air inlet 30 can be increased, and collection efficiency can be improved. Furthermore, since it becomes more difficult for the second air inlet 40 to draw in the first air EA, it is possible to prevent air containing oily smoke or odors from being blown out from the air outlet 50. As a result, discomfort to the user can be reduced, and contamination of the air path from the second air inlet 40 to the air outlet 50 can be reduced.

[0067] Furthermore, the first suction port 30 and the second suction port 40 have the same width in the x-axis direction (see FIG. 4).

[0068] With this configuration, the second suction port 40 is always located below the first suction port 30. In other words, the first suction port 30 is prevented from drawing in the second air RA. Specifically, the second suction port 40 draws in the second air RA located below the first suction port 30, thereby preventing the first suction port 30 from drawing in the second air RA. As a result, the proportion of air in the second space 90 drawn in by the first suction port 30 decreases, and the proportion of the first air EA can be increased, thereby improving collection efficiency.

[0069] Next, the second air RA is blown out from the air outlet 50 toward the cook (the front side of the cooking equipment 2) and toward the outside of the cooking equipment 2 (see FIG. 3). More precisely, the second air RA is blown out toward the cook and toward the outside of the cooking equipment 2 at an angle of approximately 45° with respect to the right side surface 26 or the left side surface 28 of the cooking equipment 2.

[0070] With this configuration, an air curtain can be formed by the second air RA blown out from the air outlet 50. In other words, the air curtain can keep the first air EA containing a lot of oily smoke or odor inside the air curtain, i.e., within the first space 80. As a result, the first air EA containing a lot of oily smoke or odor is more likely to be sucked into the first suction port 30, and collection efficiency can be improved.

[0071] The lower end of the air outlet 50 is located below the top part 6 of the cooking utensil 5.

[0072] With this configuration, it is possible to prevent the first air EA rising from the ceiling 6 from leaking outside the cooking appliance 2. In other words, the second air RA (air curtain) blown out from the air outlet 50 can more reliably keep the first air EA within the first space 80. As a result, the first air inlet 30 can more reliably draw in the first air EA, and collection efficiency can be improved.

[0073] Furthermore, the upper end of the air outlet 50 is provided at approximately the same height as the upper end of the first air inlet 30 .

[0074] With this configuration, it is possible to prevent the first air EA rising from the ceiling 6 from leaking outside the air curtain before being sucked into the first suction port 30. In other words, it is possible to more reliably keep the first air EA within the first space 80. As a result, the first suction port 30 can more reliably suck in the first air EA, and collection efficiency can be improved. do.

[0075] Furthermore, the volume of the first air EA drawn by the first air inlet 30 is greater than the volume of the second air RA drawn by the second air inlet 40.

[0076] With this configuration, it is possible to prevent the first air EA from being sucked into the second suction port 40. In other words, the second suction port 40 more reliably sucks in the second air RA. That is, by reducing the amount of second air RA sucked in by the first suction port 30, it is possible to increase the proportion of the first air EA in the air sucked in by the first suction port 30. As a result, it is possible to improve the collection efficiency. (Embodiment 2) Next, a second embodiment will be described, but the description of the same configuration as the first embodiment may be omitted or simplified.

[0077] Embodiment 2 differs from Embodiment 1 in that second air inlet 40a is provided in rear wall 60a. Second air inlet 40a in Embodiment 2 will be described using Figures 7 and 8. Figure 7 is an external perspective view of cooking exhaust device 1a and cooking equipment 2a and corresponds to Figure 1. Figure 8 is a front view of cooking exhaust device 1a and cooking equipment 2a and corresponds to Figure 4.

[0078] As shown in FIG. 7, cooking exhaust apparatus 1a includes second air inlet 40a in rear wall 60a.

[0079] The second air inlet 40a is an opening provided in the rear wall 60a. Specifically, the second air inlet 40a is a slit-shaped opening having a longitudinal direction in the horizontal direction (x-axis direction). Two second air inlets 40a are provided side by side in the vertical direction (z-axis direction). In other words, a plurality of second air inlets 40a are provided side by side along the vertical direction (z-axis direction). As shown in FIG. 8, the second air inlets 40a are provided with a predetermined distance H7 between the upper end of the second air inlet 40a and the lower end of the first air inlet 30. The predetermined distance H7 is, for example, approximately 10 mm to 100 mm. The second air inlet 40a is provided with a predetermined distance H8 between the upper end of the second air inlet 40a and the housing upper surface 11. The predetermined distance H8 is, for example, approximately 90 mm to 110 mm. Furthermore, second suction port 40a is provided with a predetermined distance H9 between the lower end of second suction port 40a and housing upper surface 11. Predetermined distance H9 is, for example, approximately 0 mm to 20 mm. In the second embodiment, the width of second suction port 40a in the x-axis direction is approximately the same as width W3 of first suction port 30. Furthermore, height H10 of second suction port 40a in the z-axis direction is, for example, approximately 10 mm to 50 mm.

[0080] With this configuration, the second suction port 40a draws air in a roughly horizontal direction. In other words, the second suction port 40a is prevented from drawing in air at a higher position than the second suction port 40a, i.e., the first air EA (see FIG. 10). As a result, the first suction port 30 can more reliably draw in the first air EA containing a large amount of oily smoke or odor, improving collection efficiency. The configuration shown in the second embodiment is particularly effective when cooking with a cooking utensil 5 that is low in the vertical direction. An example of a low cooking utensil 5 is a frying pan that is approximately 50 mm high. (Embodiment 3) Next, a third embodiment will be described, but the description of the same configuration as the second embodiment may be omitted or simplified.

[0081] The third embodiment differs from the second embodiment in that a partition plate 62 is provided between the first suction port 30 and the second suction port 40a. 2 will be described. Fig. 9 is an external perspective view of cooking exhaust device 1b and cooking equipment 2b, and corresponds to Fig. 1. Fig. 10 is a side cross-sectional view of cooking exhaust device 1b and cooking equipment 2b, and corresponds to Fig. 5.

[0082] As shown in FIG. 9, cooking exhaust device 1b includes a partition plate 62 on rear wall 60b.

[0083] The partition plate 62 is a plate-like portion that protrudes from the front surface 61b of the rear wall 60b toward the cooking equipment 2b. In the third embodiment, as shown in FIG. 10, the partition plate 62 protrudes in the y-axis direction to a position vertically above the front surface 12 of the housing 10. In other words, the length of the partition plate 62 in the y-axis direction is approximately equal to D1+D2+D3 (see FIG. 2). The partition plate 62 also has a width W1 in the x-axis direction that is approximately equal to the widths of the first and second suction ports 30 and 40a. The partition plate 62 protrudes in the vertical direction (z-axis direction) from between the first and second suction ports 30 and 40a. In other words, the partition plate 62 is provided at approximately the same height as the top portion 6 of the cooking utensil 5 in the vertical direction.

[0084] With this configuration, the partition plate 62 prevents the first air EA containing oily smoke or odor from being drawn into the second suction port 40a. In other words, the provision of the partition plate 62 allows the first suction port 30 to more reliably draw in and exhaust the first air EA. As a result, the collection efficiency can be improved. (Fourth embodiment) Next, a fourth embodiment will be described, but the description of the same configuration as the first embodiment may be omitted or simplified.

[0085] The fourth embodiment differs from the first embodiment in that a straightening plate 63 is provided at the upper end of the rear wall 60c. The straightening plate 63 in the fourth embodiment will be described with reference to Figs. 11 and 12. Fig. 11 is an external perspective view of the cooking exhaust device 1c and cooking equipment 2c, and corresponds to Fig. 1. Fig. 12 is a side cross-sectional view of the cooking exhaust device 1c and cooking equipment 2c, and corresponds to Fig. 5.

[0086] As shown in FIG. 11, the cooking exhaust device 1c includes a flow regulating plate 63 at the upper end of the rear wall 60c.

[0087] The rectifying plate 63 is a plate-shaped portion that protrudes toward the cooking appliance 2c from the leading end of the rear wall 60c, which stands vertically upward from the upper surface 11 of the housing. In other words, the rectifying plate 63 protrudes toward the cooking appliance 2c from the leading end of the rear wall 60c in the standing direction. As shown in FIG. 12, the rectifying plate 63 protrudes in the y-axis direction from the front surface 61c of the rear wall 60c to a position vertically above the front surface 12 of the housing 10. In other words, the length of the partition plate 62 in the y-axis direction is approximately equal to D1+D2+D3 (see FIG. 2). Furthermore, the partition plate 62 has a width W1 in the x-axis direction that is approximately equal to the width of the first air inlet 30 and the second air inlet 40. Furthermore, the rectifying plate 63 protrudes in an approximately horizontal direction. Furthermore, the width of the rectifying plate 63 in the x-axis direction is approximately equal to the width of the cooking exhaust device 1c. In other words, the width of the rectifying plate 63 in the x-axis direction is approximately the same as the distance between the right side surface 13 and the left side surface 15 of the cooking exhaust device 1c. The rectifying plate 63 is provided to guide the first air EA to the first air inlet 30.

[0088] With this configuration, the first air EA, which contains a lot of oily smoke or odors generated by the cooking utensils 5, is prevented from rising by the straightening plate 63 and is kept below the straightening plate 63. This makes it easier for the first suction port 30 to suck in the first air EA. As a result, the collection efficiency can be improved.

[0089] The present invention has been described above using embodiments 1 to 4. The present invention is not limited to the above embodiments. It can be easily assumed that various improvements and modifications are possible within the scope of the present invention.
