In order to achieve this object, the present invention comprises a furnace body which accommodates a gas burner and has an opening on an upper surface thereof, and an upper plate covering an upper surface opening of the furnace body, the opening being formed on the work top. In the drop-in furnace to be supported in a suspended state, at the back of the upper plate, an air vent into the inside of the main body of the furnace is provided, and at the front edge of the air vent, the air flows from the furnace side immediately near the upper side of the air vent. It is characterized in that the hood is installed.

In the present invention, since the vent is provided on the upper surface of the upper plate instead of the drop wall around the upper plate, the vent can be formed in a large area. However, in many cases, the drop-in furnace is installed in front of the wall of the kitchen, and the wind flows along the rear wall surface by burning the burner, so that the wind flows from the front of the furnace to the air vent in the rear, In this state, it is disturbed by the flow of air flowing immediately above the vent, and it is difficult to introduce combustion air from the vent. Therefore, in the present invention, since the hood is provided at the front edge of the vent to block the flow of air flowing immediately above the vent, even if there is a flow of wind flowing backward over the vent from the front of the furnace, the air is not affected. Can be absorbed from the vent and sufficient air can be supplied into the furnace body, so that good combustion can be realized. In addition, since the vent and the hood covering it are at the rear of the upper plate, the appearance of the furnace when viewed from the front is not impaired. In addition, if the hood is provided with a cover portion that also covers the upper side of the air vent, there is an effect of preventing the wind blocking effect and foreign matter from falling into the air vent. Therefore, when the hood is formed in an inclined shape in which the rear side rises from the front edge of the vent, the shape may not become large.

In addition, in the present invention, it is characterized in that the angle variable device which can change the inclination angle of the hood. Depending on the distance between the furnace and the rear wall, the flow of air is different, and the suction state of the air from the vent is different so that sufficient air can not be sucked.However, if the angle of inclination of the hood can be changed, By adjusting the angle of the hood in accordance with the interval of the sufficient air can be sucked.

According to the present invention, the upper plate can be made of a metal plate, for example, an aluminum plate having a thickness of several mm, and an opening can be provided in the rear portion of the metal plate, and it can be used as the vent.

Alternatively, a cut of one side may be formed and lifted on the rear side of the upper plate. The hood may be formed at the rear of the upper plate by the upright edge of the rear edge of the upper plate, and the rear portion of the main body may be opened to form an air vent formed under the hood. In this case, it may be folded over the entire width of the back of the upper plate, or may be raised by lifting the middle part, leaving both sides of the rear edge of the upper plate.

In the present invention, when the upper plate is made of a thick metal plate, the hood is preferably formed thinner than the other part. As a result, the processing such as folding the hood can be made very easy. Further, in the metal plate, the bending groove may be formed along the bending position when the hood is folded. This also makes it very easy to process such as causing the hood to fold.

In the present invention, there is provided a connecting member for connecting the furnace main body and the upper plate, the connecting member, the lower end is connected to the rear side of the furnace main body, the upper end is formed by hanging on the rear edge of the hood It is preferable to be connected to the connection part. In addition, you may connect to the to-be-connected part which stands up in the ventilation hole in the back part of the said furnace main body, and the connection part formed in line with the rear edge of the said hood is formed. In this way, the top plate can be firmly connected to the furnace body. Since the connecting member or the connecting portion is hidden behind the hood and can be made invisible from the front position of the stove, the top plate and the furnace body can be connected while maintaining the appearance of the top plate satisfactorily.

In addition, in this invention, you may comprise the said top board by the board body and the frame-shaped frame body made from metal. In this case, the said frame is provided with the installation part which installs the said board | plate body, and the partition border material which partitions and forms the said vent, It is preferable to form the said hood integrally with this partition frame material. As a result, a vent and a hood can be provided in the frame, and bending or the like of the plate is unnecessary. For example, a glass plate or a thick metal plate can be easily employed.

Moreover, in this invention, the connection member which connects the said furnace main body and the said rim is provided, and connects the lower end part of this connection member to the back side of the said furnace main body, and the upper end is the said lower frame at the lower side or the rear side of the said hood. It is preferable to connect to. By doing so, since the upper end of the connecting member is concealed in the lower side or the rear side of the hood, it is not visible from the front position of the furnace, and the top plate and the furnace body can be connected while maintaining the appearance of the top plate well.

In addition, in this invention, you may form a connection part in the back edge of a hood. This connection part can be employ | adopted in the case where a hood is formed by folding the rear end edge of an upper board, and when a hood is formed in a part of frame.

Moreover, in this invention, when the said furnace main body is equipped with the opening of a grill chamber in the front surface, the said upper plate is comprised by the board frame and the metal frame-shaped frame body, The installation which installs the said board body in this frame body is provided. The partition frame which partitions and forms the vent hole from a grill chamber may be provided in the back part of this part, and the hood which covers the said vent hole may be integrally formed in this partition frame material. This prevents foreign matter from falling into the main body of the furnace without damaging the aesthetics by the hood provided on the partition frame of the frame, and can smoothly guide and discharge the exhaust from the grill chamber.

In FIG. 5, 16 is a thermocouple which detects the misfire of the burner 11, and is connected to the cock 14 by the lead wire 16a.

In FIG. 4, the top edge 35 forms a frame-shaped frame by knitting two front and rear two long edges 36 and 36 and two short left and right edges 37 and 37 in a rectangle. The partition edge member 38 is inserted across the short edge members 37 and 37 at the position near the rear side. Thereby, the installation area | region of the glass plate 31 is formed between the front side edge 36, the left and right edges 37 and 37, and the partition edge 38. As shown in FIG. At the same time, the air vent 33 is formed between the partition frame 38, the left and right borders 37 and 37, and the rear frame 36.

The edges 36 and 37 of the front, rear, left and right go downward from the upper ends of the edge portions 36b and 37b and the vertical walls 36a and 37a which protrude horizontally inward from the lower ends of the vertical walls 36a and 37a. It is formed in the cross-sectional structure which has the flange parts 36c and 37c which curled in the direction. The partition edge material 38 is formed in the cross-sectional structure which has the edge part 38b which protrudes horizontally forward from the lower end of the vertical wall 38a, and the edge part 38c protrudes horizontally rearward. Each of these edge members 36, 37, 38 is integrally formed by extrusion molding of aluminum, respectively.

The long and short edges 36 and 37 are the inverse triangle head 36b1 formed at both ends of the edge 36b of the front and rear edge 36 and the edge 37b of the left and right edges 37. Is connected by caulking the triangular recessed part 37b1 formed in the both ends in (). Similarly, the triangular concave portion 37b2 formed in the middle of the shorter edge member 37 and the inverted triangular head portion 38b1 formed at both ends of the edge portion 38b of the partition frame member 38 are formed. The caulking is engaged with the frame members 37 and 38.

As shown in FIG.2 and FIG.4, the support part of the glass plate 31 is the horizontal edge part 36b, 37b of the front edge material 36, the left and right edge materials 37 and 37, and the partition frame material 38. As shown in FIG. , 37b, 38b), which is formed of a rectangular support edge side, on which a glass plate 31 is placed. The silicon caulking material 39 is filled between the glass plate 31 and the vertical walls 36a, 37a, 37a, 38a of the edge member 36, 37, 37, 38 placed in this way, and the glass plate 31 ) Is secured so as not to deviate from the saw frame 35 and watertightness is ensured. In the rear frame 36 of the upper plate 30, two screw holes 36d are formed at intervals from each other. And the screw 36e is fixed to the screw fixing protrusion 22b formed in the flange 22 of the furnace main body 20 through this screw hole 36d, and the upper plate 30 is fixed to the furnace main body 20 by this. Position is determined. In this state, the flange portions 36c and 37c of the edge members 36 and 37 cover the flange 22 of the furnace main body 20 and are grounded to the upper surface of the work top 2.

The vent 33 is formed of the vertical wall 38a of the partition frame 38 and the horizontal edges 37b, 37b, and 36b of the left and right borders 37 and 37 and the rear frame 36. As a hole part, it forms in the width direction of the upper board 30 at the back part of the upper board 30. As shown in FIG. Under the vent 33 of the upper plate 30, the rear part of the top open furnace main body 20 is located, and the vent 33 communicates continuously into the furnace main body 20. As shown in FIG. In this embodiment, since the vent hole 33 is provided on the upper surface of the upper plate 30 instead of the water drop wall around the upper plate 30 in this way, a large-area vent hole 33 is formed to receive sufficient primary air for combustion. Can be entered.

The hood 40 is provided in the vent 33. As shown in FIG.2 and FIG.3, the hood 40 is provided with the inclination part 40a which inclined upward toward the rear side from the front edge part of the vent 33. As shown in FIG. In the present embodiment, the front end portion 40b of the hood 40 is formed as a vertical wall, and the front end portion 40b of the hood 40 is in contact with the back surface of the vertical wall 38a of the partition frame 38. The front edge 33a of the air vent 33 is closed, and underneath the rear end 40d of the hood 40 is an air inlet connected to the air vent 33. The rear end portion 40d of the hood 40 is bent horizontally outward, and the long hood 40 is reinforced with the front end portion 40b.

Further, side walls 40c are formed at both side ends of the inclined portion 40a, and horizontal edge portions 37b of the left and right edge members 37 function as seating portions at the lower end portions of the side walls 40c, thereby providing a hood ( 40 is detachably installed in the vent 33. 3, when the edge part 38c protrudes a little longer than the plate | board thickness of the hood 40 behind the vertical wall 38a of the partition frame 38, the front end part of the hood 40 ( Functioning as a seating part of 40b), the hood 40 can be installed in the vent 33 more stably. In addition, the hood 40 was formed integrally by bending the inclined portion 40a, the front end portion 40b, and both side walls 40c by an aluminum plate.

The inclination of the inclined portion 40a of the hood 40 can sufficiently take the distance between the rear end portion 40d of the hood 40, which becomes the air intake portion of the hood 40, and the upper end of the rear edge member 36. Generally, about 20 to 60 degrees is good. If the inclination angle is too small, the gap between the air intake portions cannot be sufficiently taken. If the inclination angle is too large, the appearance deteriorates. In this example, the inclination angle of the inclined portion 40a was 25 degrees, and the interval between the upper end of the vertical wall 36a of the rear frame 36 and the rear end 40d was secured at 14 mm.

In FIG. 3, when the gas is burned in the burner 11, the flow of air in the upper surface of the drop-in furnace 10 rises above the vent 33 at the front of the furnace due to the upward flow by the rear wall surface 4. Face backwards. For this reason, even if the air vent 33 is installed in a large area at the back of the upper plate 30, it is hindered by the flow of air flowing immediately above the air vent 33 from the front of the furnace, and the air vent (around the air vent 33) Since air hardly enters 33, suction of the primary air for combustion into the furnace body 20 becomes difficult.

On the other hand, if the hood 40 is provided in the vent 33, the flow of air flowing backwards immediately above the vent 33 at the front of the furnace is blocked by the front of the hood 40 or bent upwards. Since the back surface of the hood 40 can be prevented, the flow of air which flows toward the rear side wall surface 4 near the upper side of the vent 33 is eliminated. Therefore, since air is sucked from the air vent 33 without being affected by the flow of air toward the rear wall surface 4, sufficient air can be supplied into the furnace main body 20 from the large air vent 33. Allow combustion. In addition, although the shape of the hood 40 may be provided in the shape of a standing wall at the front edge of the air vent 33, especially the hood 40 is equipped with the cover part which seems to cover the air vent 33, or serves as a cover part. If it is inclined to rise from the edge toward the rear, there is also an effect to block the wind and foreign matter falling into the vent.

Next, 2nd Embodiment of this invention is described with reference to FIG. 6 is an explanatory cross-sectional view showing the main parts of the second embodiment.

The flow of air varies depending on the distance between the drop-in furnace 10 and the rear wall surface 4, and as a result, the intake state of the air from the vent 33 is different so that sufficient air cannot be inhaled. have. Therefore, in this embodiment, the inclination angle of the hood 42 can be adjusted. The hood 42 is made of an aluminum plate, and the support portion 42b bent on both sides of the front portion of the hood 42 is supported by the shaft 42a formed on the left and right edge members 37, so that the hood 42 An angle variable device is formed.

Thereby, by adjusting the angle of the hood 42 in accordance with the space | interval with the rear side wall surface 4, it can be made to inhale air sufficiently. In addition, the other structure in 2nd Embodiment is basically the same as 1st Embodiment demonstrated with reference to FIGS.

Next, 3rd Embodiment of this invention is described based on FIG.

Fig. 7 is a plan view showing a top plate in a third embodiment, Fig. 8 is an explanatory cross-sectional view showing the latter part of the furnace of Fig. 7, and Fig. 9 is an exploded perspective view showing a connection member of the furnace body and the top plate, Figs. 10 and Figs. 11 is explanatory sectional drawing which shows the modification of a connection member.

The hood 45c in 3rd Embodiment was integrated with the partition frame 45 of 35 A of top edges. The hood 45c is curved upward and inclined upward from the upper end of the vertical wall 45a of the partition frame 45. 45b is an edge part which protrudes horizontally forward from the lower end of the vertical wall 45a. 46 is a support plate, and it installed in three places near the both ends of hood 45c, and a center part. The support plate 46 connects the bent portion 46a at the lower end to the horizontal edge portion 36b of the rear frame 36 by means of rivets 46b (FIGS. 7 and 9). The configuration of the top edge 35A is the same except for the top edge 35 of FIG. 4 and the partition edge member 38 thereof. In addition, since the partition frame member 45 and the hood 45c are integrated, the partition frame member 45 is finally attached to the edge members 37 on both sides. In addition, although illustration is abbreviate | omitted in FIG. 7, the top edge 35A and the furnace main body 20 are connected by the connection member 20a1, as shown to FIG. 8 and FIG.

The connecting member 20a1 connects the tongue piece 46c protruding from one side of the rear edge of the support plate 46 and the bottom of the furnace main body 20. That is, the lower connecting portion 20a2 horizontally formed at the lower end of the connecting member 20a1 is screwed to the bottom of the furnace body 20, and the upper connecting portion 20a3 of the connecting member 20a1 is supported by a screw n. It is fixed to the tongue piece 46c of 46. By doing in this way, the connection part of the upper connection part 20a3 of the connection member 20a1 and the tongue piece 46c of the support plate 46 is hidden by the hood 45c, and it does not damage the external appearance of the upper board in front of a furnace. In addition, since the screw n is exposed on the rear side of the tongue piece 46c of the support plate 46, the hood 45c is not disturbed and the connection work can be made easier.

In addition, in 3rd Embodiment, since the rear frame 36 is in the position which is not seen from the front by the hood 45c, as shown in FIG. 10, the upper connection part 20b2 of the connection member 20b1 is removed. You may make it connect to the edge material 36 with the screw n. In addition, as shown in FIG. 11, the connecting plate 36f is provided in the horizontal edge part 36b of the rear edge material 36, and the upper connecting part of the connecting member 20c1 is attached to this connecting plate 36f. You may connect 20c2) with the screw n. The screw fixing part 36g of the connecting plate 36f is inclined toward the opening direction of the rear side of the hood 45c, and the upper connecting part 20c2 of the connecting member 20c1 is the connecting plate 36f. It is formed in the shape which abuts on the back surface corresponding to the screw fixing | fixed part 36g of this. As a result, the connecting portion between the upper connecting portion 20c2 of the connecting member 20c1 and the screw fixing part 36g of the connecting plate 36f is covered by the hood 45c, which is not visible from the front of the furnace 10, thereby damaging the appearance of the upper plate. There is nothing to do. In addition, since the screw n can be fixed on the rear side of the hood 45c, the connection work on the lower side of the hood 45c can be facilitated without the hood 45c being obstructed.
