Description

  The present invention relates to a ventilator used in a kitchen of a general house or a kitchen of a restaurant.

  Various types of ventilators have been developed in the past for discharging smoke, steam, etc. generated when cooking in a heating cooker (for example, an electromagnetic cooker) installed in a general residential kitchen. However, a duct is extended to the outside from an exhaust fan embedded in the wall around the cooker (see, for example, Patent Document 1) or an exhaust port provided in the wall around the cooker. There is one in which a ventilation fan is arranged in the vicinity of the downstream opening (see, for example, Patent Document 2).

  In the ventilation device (built-in type suction hood) described in Patent Document 1, the slit-like suction port is arranged on the wall surface facing the cooker so as to form a quadrangle, and the suction wind speed is increased using the venturi effect. Thus, the exhaust efficiency is improved. Moreover, in the ventilator (exhaust device for cooking) described in Patent Document 2, a duct connected to the exhaust port is disposed downward along the outer wall, and a metal heat dissipating bar is arranged at the exhaust port.

Japanese Patent Laid-Open No. 2004-3828 JP-A-61-202032

  In the case of the ventilation device (built-in suction hood) described in Patent Document 1, the slit opened for sucking smoke and vapor has a very thin shape in order to improve exhaust efficiency. For this reason, the slit is easily soiled by smoke or steam, and oil is easily accumulated in the slit. However, as described above, since the slit has a very thin shape, it is difficult to clean.

  On the other hand, in the case of the ventilator (exhaust device for cooking) described in Patent Document 2, the vertical wall around the cooker is provided with an exhaust port that is greatly opened in the lateral direction. It can be discharged outdoors by the generated air flow. However, since a large air blower is required to generate a predetermined air flow, the device itself tends to increase in size and power consumption. Further, since the exhaust port is wide open in the lateral direction, the oil smoke may be generated by the cross wind generated during operation, which may reduce the exhaust efficiency.

  The problem to be solved by the present invention is to provide a ventilating device that can efficiently ventilate with a relatively small air volume, that oil is not easily stored in the suction port, and that is easy to clean and maintain.

  A ventilator according to the present invention comprises an exhaust path communicating with a suction port provided around a cooking device disposed in a building, and an exhaust device disposed downstream of the exhaust path. The front view shape is a vertically long shape. Here, the vertically long shape is a broad concept including a vertically long rectangular shape, a vertically long oval shape, a vertically long elliptical shape, and the like.

  With such a configuration, since the region where the suction action of the vertically long suction port extends can be secured widely in the vertical direction, cooking exhaust having the property of diffusing while rising is efficient with a relatively small air volume It can be well ventilated. In addition, cooking exhaust sucked into the suction port is quickly exhausted by an exhaust device arranged downstream of the exhaust path, so that oil is not easily stored in the suction port, and the suction port has a simple structure with a vertically long shape. Therefore, cleaning and maintenance are easy. In addition, since the suction port has a vertically long shape, even when cooking exhaust is burned by wind from a different direction due to movement of a person or opening / closing of a door, it can be efficiently discharged to the outdoors.

  Here, if the suction port is opened at a plurality of locations aligned in the horizontal direction in the region facing the cooker, the region where the suction action of the suction port can be widely secured also in the horizontal direction. Can be efficiently ventilated, improving ventilation performance. In this case, it is desirable to provide the suction port at a position corresponding to the heating portion of the cooking device (portion on which the pan or frying pan is placed), so that cooking exhaust generated from the pan or frying pan can be quickly sucked in. become able to.

  On the other hand, if the lower edge portion of the suction port is provided at a height of 0 to 400 mm from the upper surface of the cooker, cooking exhaust such as a pan or a frying pan placed on the upper surface of the cooker. Because it is close to the generating part, it is possible to suck in the generated cooking exhaust without leakage, and to minimize the influence of wind from different directions due to movement of people and opening and closing of doors etc. it can. If the distance from the upper surface of the cooker to the lower edge of the suction port is greater than 400 mm, cooking exhaust diffuses into the room on the way to the suction port and leaves the suction port. Tend to be easily affected by winds from different directions due to wind. For this reason, the said range is suitable.

  Further, if the ratio of the maximum vertical size and the maximum horizontal size of the front view shape of the suction port is set to 20: 1 to 5: 1, a wide area in which the suction action of the suction port extends can be secured in the vertical direction. The cooking exhaust gas having the property of diffusing while rising can be quickly and efficiently ventilated from a region including a place close to the generation portion with a relatively small air volume. In addition, adverse effects due to winds from different directions due to movement of people and opening / closing of doors can be avoided.

  Note that if the ratio of the maximum vertical size and the maximum horizontal size of the front view shape of the suction port deviates from 20: 1, the suction port becomes a very elongated shape, so that the suction sound increases and cleaning becomes difficult. Moreover, it becomes easy to become dirty by cooking exhaust, and to accumulate oil inside. Furthermore, since the suction port is vertically long, it is necessary to increase the size in the vertical direction, leading to an increase in size of the apparatus and deterioration in workability. On the other hand, if the ratio between the maximum vertical size and the maximum horizontal size deviates from 5: 1, the area where the suction action of the suction port extends cannot be secured widely in the vertical direction, and the location where the cooking exhaust is close to the generation part is included. It becomes impossible to inhale quickly and efficiently from the area. Therefore, the ratio of the maximum vertical size and the maximum horizontal size of the front view shape of the suction port is preferably within the above-described range.

  Next, a ventilator according to the present invention comprises an exhaust path communicating with a suction port opened around a cooker disposed in a building, and an exhaust apparatus disposed downstream of the exhaust path, wherein the suction The mouth is divided into a plurality of suction openings arranged in the vertical direction, and a guide member for guiding cooking exhaust is provided in the suction openings.

  With such a configuration, since it becomes possible to attract the cooking exhaust that has entered the region where the suction action of the suction port reaches is suppressed by the guide member, it can be attracted to any of the plurality of suction openings. The cooking exhaust having the property of diffusing can be efficiently ventilated with a relatively small air volume. In addition, cooking exhaust sucked into the suction port is quickly discharged by an exhaust device disposed downstream of the exhaust path, so that oil or the like is hardly stored in the suction port, and cleaning and maintenance are easy. In addition, it is possible to avoid the influence of the cooking exhaust by the wind from different directions due to the movement of the person, the opening and closing of the door, etc., so that the exhaust efficiency can be improved.

  Here, if the plurality of guide members are arranged such that the suction angle of the cooking exhaust to the lower suction opening among the plurality of suction openings is closer to the vertical than the suction angle of the cooking exhaust to the upper suction opening The cooking exhaust immediately after it is generated from the cooking utensil can be promptly guided to the lower suction opening before it rises and diffuses, so it is possible to efficiently ventilate with a relatively small air volume, and the ventilation efficiency is further improved. . Further, it is possible to suppress the influence of burning of the cooking exhaust due to winds from different directions due to movement of people, opening and closing of doors, and the like.

  In addition, the inclination angle of the guide member provided in the lower suction opening may be 20 to 50 degrees, and the inclination angle of the guide member provided in the upper suction opening may be 45 to 80 degrees. Here, the inclination angle of the guide member means an angle formed by the opening surface of each suction opening and the guide member.

  With such a configuration, the area where the suction action of the lower suction opening reaches is larger than the area where the suction action of the upper suction opening extends, so that most of the cooking exhaust immediately after generated from the cooking utensil is sucked from the lower suction opening Can do. Therefore, the influence of the burning of the cooking exhaust due to the wind from different directions due to the movement of the person and the opening / closing of the door is suppressed, and a further excellent ventilation efficiency can be obtained.

  In addition, if the inclination angle of the guide member provided in the lower suction opening is smaller than 20 degrees, the amount of cooking exhaust sucked from the lower suction opening is reduced, and the cooking exhaust tends to diffuse into the room, and more than 50 degrees. Then, the effect of inducing cooking exhaust to the suction port decreases, and it tends to be easily affected by wind from different directions due to movement of people and opening and closing of doors, etc., and cooking exhaust tends to diffuse into the room Occurs. Further, if the inclination angle of the guide member provided in the upper suction opening is smaller than 45 degrees, cooking exhaust deviating from the lower suction opening cannot be guided well to the suction opening, and the amount of cooking exhaust sucked from the upper suction opening is reduced. A tendency to diffuse into the room arises, and if it exceeds 80 degrees, the effect of guiding the cooked exhaust to the suction port decreases, and the cooked exhaust deviated from the lower suction opening tends to diffuse into the room as it is. Therefore, the inclination angle of the guide member provided in the lower suction opening and the inclination angle of the guide member provided in the upper suction opening are preferably within the above ranges, respectively.

  According to the present invention, it is possible to provide a ventilator that can efficiently ventilate with a relatively small air volume, does not easily store oil in the suction port, and is easy to clean and maintain.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a front view showing a ventilator according to a first embodiment of the present invention, FIG. 2 is a cross-sectional view taken along line AA in FIG. 1, and FIG. 3 is a front view showing a use state of the ventilator shown in FIG. 4 is a partially enlarged view of the ventilator shown in FIG. 3, and FIG. 5 is a vertical sectional view showing a use state of the ventilator shown in FIG.

  As shown in FIG. 1 and FIG. 2, the ventilator 10 of the present embodiment is an exhaust path that communicates with two suction ports 14 that are opened in a wall 13 in front of an electromagnetic cooker 12 disposed in a building 11. 15 and an exhaust device 16 disposed downstream of the exhaust path 15. As shown in FIG. 1, the front view shape of the two suction inlets 14 is a vertically long rectangular shape, and they are arranged in parallel with each other at a distance in the horizontal direction. In the present embodiment, the vertical opening size (vertical size) of the suction port 14 is 320 mm, the horizontal opening size (horizontal size) is 20 mm, and the interval between the two suction ports 14 is the heating portion of the electromagnetic cooker 12. However, the present invention is not limited to this.

  Since the front view shape of the suction port 14 is a vertically long rectangular shape, a wide area in which the suction action of the suction port 14 reaches can be secured in the vertical direction. For this reason, as shown in FIG. 5, the cooking exhaust S generated from the cooking utensil 17 in use on the electromagnetic cooker 12 and having the property of spreading while rising is quickly sucked from an area including a place near the generation part. Inhalation into the mouth 14 is possible. Further, even when cooking exhaust is blown by winds from different directions due to movement of people or opening / closing of doors, it is possible to efficiently ventilate with a relatively small air volume.

  Moreover, the cooking exhaust S sucked into the suction port 14 is quickly discharged out of the building 11 by the exhaust device 16 disposed downstream of the exhaust path 15, so that oil or the like is not easily stored in the suction port 14. Furthermore, since the suction port 14 has a simple structure having a vertically long rectangular shape, cleaning and maintenance are easy.

  Moreover, since the two suction inlets 14 are arranged in the horizontal direction on the wall body 13 that is the area facing the electromagnetic cooker 12, a wide area in which the suction action of these suction inlets 14 extends in the horizontal direction is ensured. can do. Therefore, as shown in FIG. 3, cooking exhaust S generated from the cooking utensil 17 on the electromagnetic cooker 12 can be efficiently ventilated, and excellent ventilation performance is exhibited.

  On the other hand, as shown in FIG. 4, since the height T from the upper surface 12a of the electromagnetic cooker 12 to the lower edge part 14b of the suction inlet 14 is about 220 mm, it is mounted on the electromagnetic cooker 12 and used. The cooking exhaust S generated from the cooking utensil 17 can be sucked in without leakage.

  Moreover, as shown in FIG. 4, since the ratio (aspect ratio) of the maximum vertical size 14v and the maximum horizontal size 14h of the suction port 14 is about 16: 1, cooking having a property of spreading while rising after generation. The exhaust S can be efficiently ventilated with a relatively small air volume in a vertically long region including a portion close to the place of occurrence.

  In the ventilator 10 of the present embodiment, as shown in FIGS. 3 and 5, the two suction ports 14 are opened in a front panel 18 having a rectangular shape in front view, and the front panel 18 communicates with the exhaust path 15. In this state, the shape of the front view provided on the wall body 13 is detachably mounted in the rectangular opening 19 in an inscribed state. Therefore, it is possible to remove the front panel 18 from the opening 19 and perform cleaning and maintenance on the back surface of the front panel 18 and the opening 19, and the workability is also good.

  Next, a second embodiment of the present invention will be described based on FIG. FIG. 6 is a vertical sectional view showing a use state of the ventilator according to the second embodiment. In addition, the part which attached | subjected the code | symbol same as the code | symbol shown in FIGS. 1-5 in FIG. 6 is a part which has the same structure and function as the component part of the ventilator 10 mentioned above, and abbreviate | omits description.

  In the ventilator 10x shown in FIG. 6, the exhaust path 15x communicating with the two suction ports 14 provided in the wall body 13x in front of the electromagnetic cooker 12 disposed in the building is directed downward of the wall body 13x. The exhaust device 16 is disposed downstream of the exhaust path 15. By adopting such a configuration, the duct length is shorter than that of the first embodiment, so that the construction can be simplified. Moreover, since the position of the exhaust device 16 is relatively low and inconspicuous, the appearance of the entire building is not impaired.

  Next, a third embodiment of the present invention will be described with reference to FIGS. FIG. 7 is a front view showing a ventilation device according to a third embodiment of the present invention, and FIG. 8 is a sectional view taken along line BB in FIG. 7 and 8, the parts denoted by the same reference numerals as those shown in FIGS. 1 to 5 are parts having the same structure and function as the constituent parts of the ventilator 10 described above, and the description thereof is omitted. .

  As shown in FIGS. 7 and 8, in the ventilator 10y of the present embodiment, plate-like guide members 14y are provided on both the left and right sides of the two suction ports 14 provided in the front panel 18y. As shown in FIG. 8, the guide members 14 y provided in pairs at the two suction ports 14 are arranged such that the distance between the tips is wider than the maximum horizontal size 14 h of the suction port 14. By arranging such a guide member 14y, when the generated cooking exhaust reaches the vicinity of the suction port 14, it can be quickly guided to the suction port 14 by the guide member 14y, so that the exhaust efficiency is improved.

  In addition, the guide member 14y can also be made into the structure which can open and close the suction inlet 14. FIG. With such a structure, since the guide member 14y is opened only when the ventilation device 10y is used, and the suction port 14 is closed with the guide member 14y when not used, the indoor airtight state can be maintained. It can also be used in highly airtight houses, and can prevent outside air from being blown into the kitchen.

  Next, a fourth embodiment of the present invention will be described based on FIG. FIG. 9 is a front view showing a ventilation device according to a fourth embodiment of the present invention. In FIG. 9, the parts denoted by the same reference numerals as those shown in FIGS. 1 to 5 are the parts having the same structure and function as the constituent parts of the ventilator 10 described above, and the description thereof is omitted.

  In the ventilator 10z of this embodiment, only one suction port 14 is opened in the front panel 18z. The suction port 14 is opened at the central portion in the left-right direction (horizontal direction) of the front panel 18z. In addition, since the number of the suction inlets 14 is not limited, it is possible to open three or more, but in that case, the position of each suction inlet 14 is a position corresponding to the heating portion of the electromagnetic cooker 12, for example, When viewed from the user of the electromagnetic cooker 12, it is desirable that the center of each suction port 14 and the center of the heating portion of the electromagnetic cooker 12 be provided at a position that is generally linearly aligned in the front-rear direction.

  Next, a fifth embodiment of the present invention will be described with reference to FIG. FIG. 10 is a front view showing a ventilation device according to a fifth embodiment of the present invention. In FIG. 10, the part which attaches | subjects the code | symbol same as the code | symbol shown in FIGS. 1-5 is a part which has the same structure and function as the component part of the ventilator 10 mentioned above, and abbreviate | omits description.

  In the ventilation device 20 shown in FIG. 10, by attaching the front panel 18a whose left-right size smaller than the opening 19a is detachably attached to the opening 19a having a rectangular shape in front view established in the wall body 13, Suction ports 14a are respectively provided on the left and right of the front panel 18a. The suction port 14a is a vertically long rectangle, and is arranged so as to be parallel to each other. In the case of this embodiment, since the two suction inlets 14a can be formed without providing a penetration part in the front panel 18a, the structure can be simplified. Further, since the front panel 18a is slidable in the left-right direction, the opening size of the left and right suction ports 14a can be changed. Accordingly, the opening size of the left and right suction ports 14a can be set according to the state of cooking exhaust from the left and right cooking utensils 17, and when only one cooking utensil 17 is used, the front panel 18a is opened to the opening 19a. The suction port 14a can be set only on one of the right side and the left side of the opening 19a.

  Next, a sixth embodiment of the present invention will be described based on FIGS. FIG. 11 is a vertical sectional view showing a ventilator according to a sixth embodiment of the present invention, and FIG. 12 is a partially enlarged view of the ventilator shown in FIG. 11 and 12, the parts denoted by the same reference numerals as those shown in FIGS. 1 to 5 are parts having the same structure and function as the constituent parts of the ventilator 10 described above, and the description thereof is omitted. .

  In the ventilator 30 shown in FIGS. 11 and 12, the exhaust path 35 communicating with the suction port 34 established in the wall 13 in front of the electromagnetic cooker 12 disposed in the building 11, and downstream of the exhaust path 35. And an exhaust device (not shown) arranged in the upper part, and the suction port 34 is partitioned into an upper suction opening 34a and a lower suction opening 34b arranged in the vertical direction, and at the upper ends of the upper suction opening 34a and the lower suction opening 34b. Guide members 38a and 38b for suppressing the rise of cooking exhaust S are provided. The inclination angle 36a of the guide member 38a is set to 65 degrees, and the inclination angle 36b of the guide member 38b is set to 35 degrees.

  With such a configuration, the rise of the cooked exhaust S that has entered the region where the suction action of the suction port 34 reaches is suppressed by the guide members 38a and 38b, and either the upper suction opening 34a or the lower suction opening 34b. Since it can be attracted, the cooking exhaust S having the property of diffusing while rising can be efficiently ventilated with a relatively small air volume. In addition, the cooking exhaust S sucked into the suction port 34 is quickly discharged by an exhaust device (not shown) disposed downstream of the exhaust path 35, so that it is difficult for oil or the like to be stored in the suction port 34. Maintenance is also easy.

  12, the inclination angle 36b of the lower guide member 38b is set to 35 degrees, and the inclination angle 36a of the upper guide member 38a is set to 65 degrees, thereby setting the inclination angle 36b of the lower guide member 38b to 65 degrees. Since the state is set to be nearly vertical, the suction angle R2 of the cooked exhaust S into the lower suction opening 34b is closer to the vertical than the suction angle R1 of the cooked exhaust S into the upper suction opening 34a. Therefore, before the cooking exhaust S immediately after generated from the cooking utensil 17 diffuses upward, it can be promptly guided to the lower suction opening 34b. For this reason, it is possible to efficiently ventilate with a relatively small air volume, and excellent ventilation efficiency is obtained. Moreover, as shown in FIG. 11, the cooking exhaust S generated from the cooking utensil 17 is mainly sucked from the lower suction opening 44b, and the cooking exhaust S deviating from the lower suction opening 44b is sucked from the upper suction opening 44a.

  Further, as shown in FIG. 12, since the opening area of the lower suction opening 34b is made larger than the opening area of the upper suction opening 34a, the region where the suction action of the lower suction opening 34b reaches is the suction action of the upper suction opening 34a. It is wider than the area. Therefore, the cooking exhaust S (see FIG. 11) immediately after it is generated from the cooking utensil 17 can be sucked very efficiently, and excellent ventilation efficiency can be obtained. In addition, since the opening area of the upper suction opening 34a and the upper suction opening 34a is not limited, it can also be made equal.

  Next, based on FIG. 13, FIG. 14, 7th Embodiment of this invention is described. 13 is a perspective view showing a ventilator according to a seventh embodiment of the present invention, FIG. 14 is a side view showing a use state of the ventilator shown in FIG. 13, and FIG. 15 is a guide member constituting the ventilator shown in FIG. It is a side view which shows the storage mechanism.

  As shown in FIGS. 13 and 14, in the ventilator 40 of the present embodiment, the upper suction lined up in the vertical direction with the suction ports 44 opened in the wall body 13 in front of the electromagnetic cooker 12 disposed in the building. Guide members 48a and 48b are provided at the upper ends of the upper suction opening 44a and the lower suction opening 44b, respectively. The guide member 48a is formed by bending a plate material into a substantially U shape, and the guide member 48b has a flat plate shape. The inclination angle 46a of the guide member 48a is set to 65 degrees, and the inclination angle 46b of the guide member 48b is set to 35 degrees.

  The cooking exhaust S generated from the cooking utensil 17 is mainly sucked from the lower suction opening 44b, and the cooking exhaust S deviating from the lower suction opening 44b is sucked from the upper suction opening 44a. Further, the front edge portion 48af of the upper guide member 48a protrudes in the direction of the cooking utensil 17 from the front edge portion 48bf of the lower guide member 48b, so that the oil smoke diffused in the air is opened into the upper suction opening. It can guide to 44a and can inhale efficiently. Further, since guide portions 48g are formed in a hanging shape on both the left and right sides of the guide member 48a, the diffused oil smoke can be captured and guided to the upper suction opening 44a, and the cooking exhaust S in the lateral direction can be obtained. Can be suppressed.

  Further, as shown in FIG. 15, the guide members 48a and 18b can be rotated in the direction of the arrows about the support shafts 48ax and 48bx, respectively, so that they remain inclined as shown in FIG. When in use, the guide members 48a and 18b can be stored in a suspended state. During storage, the front surface of the guide member 48b is covered with the guide member 48a, and the guide member 48a is substantially flush with the wall body 13. In the present embodiment, when the guide members 48a and 18b are rotated about the support shafts 48ax and 48bx, respectively, the moving region of the front edge portion 48af of the guide member 48a and the front edge portion 48bf of the guide member 48b are obtained. The moving region is substantially coincident with at least the lower end portion of the lower suction opening 44b.
