TECHNICAL FIELD This invention relates to the drop-in furnace which is assembled, for example in the open hole of countertops, such as a system kitchen.

Fig. 19 is a perspective view showing a part of the system kitchen, showing a drop-in furnace accommodated inside the main body. 21 is a partial sectional view of the drop-in furnace which shows the longitudinal direction part of the system kitchen in cross section. In these drawings, a burn-in furnace is provided with a burner on an upper surface, and an operation handle p and a grill door q are provided on the front side. The furnace case (e) having three basic burners (C1 to C3) is fitted inside the open hole of the counter top (a), and the periphery of the open hole of the counter top (a) by the upper flange. Hang on Then, only the upper half of the burners C1 to C3 is placed on the upper side of the counter top a, and the top plate b covering the open hole of the furnace case e except for these is provided, and the flange of the furnace case e is provided. As shown in the figure, the outer periphery n is suspended from the open hole edge of the counter top a. The upper plate b is provided with trivets d provided with the projection pieces g corresponding to the flame hole portions of the burners C1 to C3, respectively. The trivet (d) is connected to each of the protrusion pieces (g) and the support body, and the frame (h) to be contacted on the upper plate (b) is integrally formed. Moreover, in recent years, the drop of the counter top (a) surface and the protrusion (g) of the trivet (d) so that the heated objects such as a pot can be easily raised and lowered on the trivet (d) of the countertop (a) surface So-called flattening is taking place to make the setting as small as possible. That is, as shown in FIG. 22 (a), with respect to the height H1 of the counter top (a) surface and the upper side of the projection piece g, as shown in FIG. 22 (b), the upper board b and the furnace case e ) The depth of fall is reduced by making H2 deeper and making the height H2. As shown in Fig. 20, the drop is reduced by using the tricycle d having a low height.

In the drop-in furnace accommodated in the said system kitchen, as shown in FIG. 19, compared with a normal furnace, the upper board b which covers this is also large. In addition, as shown in Fig. 22B, the upper plate b is deepened by the flattening. Therefore, in such a top board (b), it was troublesome to clean the dirt by the soup etc. which flowed into the top board (b). On the other hand, according to the said structure, as shown by the dashed-dotted line of FIG. 21 according to the said flattening, the bottom part i and the side wall of the top board b by the radiant heat of the flame F emitted from the burner C1. (v) becomes easy to heat. Further, the furnace case e is deeply sandwiched, and the inside of the furnace case e is also heated through the internal space j by the radiant heat of the burner C1 at the lower side of the upper plate b. Therefore, there was a problem that the counter top a is overheated by such heating.

The present invention has been made in view of the above problems, and can easily clean the soiled dirt due to the soup or the like that flowed down to the top plate, while preventing the countertop from overheating by suppressing the temperature rise of the top plate and the member connected thereto. To provide a drop-in cooker.

In order to solve the above problems, the drop-in furnace according to claim 1, which is formed by "hanging in a state fitted in the open hole of the counter top formed in the counter top, protruding outward from the furnace case provided with the burner and the upper end of the circumferential wall, is provided. The formed flange is supported in contact with the periphery of the open hole of the counter top, and the bottom part surrounded by the circumferential wall has a open hole in which the burner is placed, and a first space between the outer periphery of the burner and the open hole. The upper plate has a gap formed therein, a support body supporting the object to be heated, and a frame connecting the support, and has a trivet and a open hole in which the burner is positioned as if descending into the upper plate. In the upper plate and the upper and lower gaps are formed and provided with an auxiliary upper plate placed on the upper plate, the outer of the auxiliary upper plate In the circumferential gap between the top plate it is further characterized in that the first gap is connected to a second gap is formed, leading to "through the vertical gap.

Therefore, the top plate is prevented from being directly soiled by the soup, etc., while the dirty auxiliary top plate can be removed from the top plate, so that the whole plate can be easily cleaned.

Since the auxiliary upper plate was formed by forming an upper gap with the upper plate at the upper side of the upper plate, it is insulated by the gap formed by the upper and lower gaps, and the radiant heat due to the flame of the burner is suppressed from reaching the upper plate side. Then, in the outer periphery of the auxiliary top plate, a second gap is formed between the top plate and becomes a vent hole connected to the countertop side, so that the air inside the furnace case is mainly the following vent passage, that is, the top plate and the burner. Through the first gap, which is a gap with the outer peripheral part, it is a passage of air flowing from the second gap to the counter top side through the gap between the upper plate and the auxiliary upper plate. The upper plate is cooled by the circulation of air, and the temperature rise is further suppressed in addition to the heat insulation by the auxiliary upper plate. Moreover, the member etc. which were provided in a row by the upper board by cooling of the said air are also cooled. These points can prevent overheating of the counter top.

According to this solution, since the opening between the open hole of the auxiliary upper plate and the outer peripheral part of the burner is substantially closed, in addition to the one described in claim 1, the spilled broth and the outer hole of the burner It is prevented to enter the upper plate side through the gap. In addition, as the influence of the upper plate due to the radiant heat caused by the flame of the burner is reduced, the air passage inside the furnace case passes through the gap between the upper plate and the auxiliary upper plate from the first gap, and passes through the second gap to the counter top side. Since it is formed, the temperature rise of the upper plate and the member provided in succession thereof is suppressed and the heating of the countertop can be prevented. In addition, the occlusion between the open hole of the auxiliary upper plate and the outer circumferential portion of the burner is not limited to the case where the open hole portion of the auxiliary upper plate is formed by fitting the outer circumferential portion of the burner, for example, the open hole of the auxiliary upper plate. The covering can be used between the outer periphery of the burner. In other words, the inner circumference of the covering is fitted to the outer circumference of the burner while the outer circumference covers the open hole of the auxiliary top plate.

The drop-in furnace of Claim 3 is limited to what was described in Claim 1, "It connects to the upper space of the said auxiliary upper plate, and communicates between the said open hole of the said auxiliary upper plate, and the said outer peripheral part of the burner, And a third gap connected to the first gap to communicate with the first gap. According to this solution, since the third gap is formed between the open hole of the auxiliary upper plate and the outer periphery of the burner, the air inside the furnace case is separated from the first gap as described above by the gap between the upper plate and the auxiliary upper plate. In addition to the ventilation passage leading from the second gap to the countertop side, a ventilation passage leading from the first gap through the third gap to the upper space of the auxiliary top plate is formed. Therefore, in addition to the heat-blocking effect and the cooling effect of the ventilation on the auxiliary top plate of claim 1, and the radiant heat, the ventilation of the burner to the flame hole side can be promoted and the combustion can be improved.

In addition, this 3rd gap can be formed with the following structures. For example, a covering is used between the opening of the auxiliary top plate and the outer periphery of the burner, and the inner periphery of the covering is externally fitted to the outer periphery of the burner, while the outer periphery is a perforated opening of the auxiliary top plate. It overwrites. In this covering, a through hole corresponding to the third gap is formed at a position outside the open hole of the upper plate. According to such a configuration, while the above-mentioned ventilation is secured by the third gap, the covering which covers the gap between the opening of the top plate and the outer circumference of the burner can be prevented from entering the furnace case as much as possible. have.

Further, as another covering, the inner circumference of the covering can be fitted to the outer circumference of the burner, while the outer circumference can be interposed in the vertical gap between the auxiliary top plate and the top plate. According to this configuration, the third gap is formed between the outer periphery of the covering and the hole in which the auxiliary top plate is opened. Therefore, even in this configuration, the ventilation is ensured, the outer periphery of the auxiliary top and the covering and the top plate are prevented from entering the furnace case, and the air is blown through the third gap. Guided to the side. With respect to this covering, a larger diameter portion is formed on the outer periphery of the covering than the opening of the auxiliary top plate and the top plate, and is formed larger than the opening of the auxiliary top plate and smaller than the opening of the top plate. A diameter portion can be formed to form a wall portion extending upward from this small diameter portion. By doing so, the first gap formed by the open hole of the upper plate and the small diameter portion of the outer covering of the covering is largely formed, so that the ventilation is better, and the spilled broth is caused by the opening of the auxiliary top plate and the outer circumference of the burner. Even if it falls to the covering through the third gap, it is blocked by the wall portion provided in the small diameter portion and guided to the wall portion without bleeding into the first gap to be led to the upper plate reliably.

In addition, in the said example, although the notch part and the support part are not formed in the frame pieces 52f3 and 52f4 of both sides, you may form. Therefore, when the trivet 52 is placed on the mounting portion 39 of the upper plate 3, a gap 52h is formed between the cutout 52e and the upper plate 3 as shown in FIGS. 9 and 11. The gaps 51h (D) and 52h (L) of these frame bodies 51f and 52f, as well as the gaps E and M between the frame bodies 51f and 52f and the upper plate 3 circumferential wall 32, It becomes a ventilation passage through which the upper part of the counter top 7 and the burners 61, 62, 63 are ventilated. In addition, since the front tricycle 51 and the rear tricycle 52 are adjacent to each other, and the frames 51f and 52f overlap each other, the front tricycle 51 side to the rear tricycle 52 side on the upper surface of the upper plate 3. Although aeration of air is prevented, even when the pan is placed on the trivets 51 and 52 by the formation of the bottom upper edge portions 51j and 52j, a gap J is formed between the bottom upper edge portions 51j and 52j and the bottom of the pot. It is easily ventilated between both trivets 51 and 52. In addition, the part where these frames 51f, 52f overlap each other is added to the lower top edge part 51j, 52j of the said tricycle, and the lower side part of the frame 51f, 52f of a trivet and the bottom part of the upper board 3 are also included. Since there is a gap between the 36 and the aeration, ventilation between the tricycles 51 and 52 can be easily achieved. In the drawing example, the gaps 51h (D) and 52h (L) are formed by forming the cutouts 51e and 52e on the frame side, but instead of the cutouts, the cutouts 51e and 52e are formed flat without forming the cutouts on the frame side. Thus, a plurality of convex portions may be formed on the upper plate 3 side placing portion 39, and the same gap may be formed between the double convex portion and the lower side of the frame (not shown). Alternatively, the bottom portion 36 of the upper plate 3 may be a mounting portion of the trivet 52. Also in this case, the plurality of cutouts 51e and 52e are formed on the lower sides of the frames 51f and 52f, or the lower sides of the frames 51f and 52f are in a straight line, and this is formed in the bottom portion 36. The ventilation gap may be secured by supporting the two convex portions. In addition, the trivet projects the outer ends of the projection pieces 51a and 52a more than the frames 51f and 52f so that the protrusions are placed at the end of the circumferential wall 32 or the jaw portion 31 of the upper plate 3. The gap may be formed by hanging the lower side suspended from the bottom portion 36.

In addition, in the concave portions 45 and 45 formed on the peripheral wall upper edge portion 41 of the auxiliary upper plate 4, the front tricycle 51 and the rear tricycle 52 are positioned at the upper side thereof, as shown in FIG. The adjacent frame pieces 51f1 and 52f1 of the trivets adjacent to each other among the frames 51f and 52f are formed so as to span the recesses 45 and 45, respectively. Therefore, contact between the trivets 51 and 52 and the auxiliary upper plate 4 can be avoided, and the trivets 51 and 52 can be directly placed on the upper surface of the upper plate 3 without interposing the auxiliary upper plate 4. If the trivets 51 and 52 are placed on the upper surface of the auxiliary top plate 4, the length of the auxiliary top plate 4 itself in addition to the error in the processing accuracy of the trivets 51 and 52 itself or the deformation due to thermal warping, etc. Errors or column distortions beyond the contour path are added. Therefore, the cumulative error becomes large, and as a result, the trivets 51 and 52 are easily shaken on the upper plate 3. However, since the trivets 51 and 52 are placed directly on the upper plate 3 as described above, this problem can be solved. In this manner, even when the trivets 5 (51, 52) are divided so as to be easy to clean, such as cleaning, the trivets 5 (51, 52) can be placed on the upper plate 3 directly. Since the adjacent portions of the plurality of trivets, that is, the adjacent pieces 51f1 and 52f1 of the frame 51f and 52f, are stretched over the concave portions 45 and 45, it is suitable for the case where the trivets are divided and placed in plurality. While it is possible to easily cope with the enlargement of the furnace, it is also possible to reduce the size of the trivet itself. In addition, since the adjacent portions of the trivets were allowed to extend over the concave portions 45 and 45, the length in the height direction can be reduced, and flattening of the drop-in furnace can be achieved. In addition, although the recessed parts 45 and 45 were formed in the circumferential wall upper edge part 41 side of the auxiliary upper board 4 in the drawing example, on the contrary, the circumferential wall upper edge part 41 is normally left as it is, and it is adjacent to a trivet. The cutouts 51e and 52e as described above may be formed separately on the pieces 51f1 and 52f1. Also in this case, since the length in the height direction can be reduced, flattening of the drop-in furnace can be achieved.

The drop-in furnace of the present invention has the configuration as described above and is fitted into the open hole of the counter top 7 to be assembled. 2, 3, and 9, when assembling, a gap generated between the lower side of the counter top 7 and the upper edge portion 11 of the furnace body 1 on the front operation portion 10 side. The pillar 9 is attached to (H3) (refer FIG. 9). The pillar 9 has a height at which the difference S between the depth of the deep suspension frame 2 and the shallow suspension frame 20 substantially matches a predetermined height (as shown in FIG. 18) to correspond to the gap H3 as the filler member. And an upper side 92 and a lower side 93 so as to open on the side of the furnace body. The attachment of the filler 9 is inserted into the window 25 formed in the circumferential wall 21 of the hanging frame 2 through the tongue piece 92a extending inwardly from the upper side 29, and the window 25 ) Is fixed to the bent piece 24 formed by cutting off the circumferential wall 21 by the screw 26. Then, the tip 93a extending inwardly from the lower side 93 of the filler 9 is fitted into the gap between the upper side portion 11 of the working body 1 and the hanging body 2 and fixed. In the filler 9, vent holes 91 are formed at both ends, and the filler 9 is formed so as to vent with the inner side of the furnace body 1.

The drop-in furnace of the present invention can make it possible to cope with various system kitchens different from the height of the worktop, that is, the height of the upper edges 51b and 52b, and as described above, the furnace body 1 and the hanging frame 2 ) Is securely connected and detached by screws 99a and 99b. Therefore, when the workpiece height is changed from the drop-in furnace of the height H1 of FIG. 22 (a) to the drop-in furnace of the height H2 of FIG. (1) and the burners 61, 62, and 63 can be used as they are as common components. That is, as shown in FIG. 18, this embodiment showed tricycle 50, the upper plate 30, and the suspension frame 20 which are components of the drop-in furnace of the height H1 shown by the column on the right side of the figure in the column on the left side of the figure. As in the example, the main furnace body 1 and the burners 61, 62, and 63 are replaced with the tricycles 5, the deep top plate 3, and the deep hanging frame 2 of the drop furnace of the height H2. You can change the height of the workstation as it is. And, as described above, the main body (1) and the hanging frame (20) can be freely connected and fixed, assembling according to various types of combinations is possible, for example, the height of H2 which is the case opposite to the above The change from the drop-in stove to the drop-in stove of height H1 can be easily coped with.

In addition, when changing into the above-mentioned deep upper plate 3 or the suspension frame 2, as shown in FIG. 9, the lower part of the counter top 7 and the upper edge part of the main furnace body 1 in the front operation part 10 side are shown. The gap H3 is formed between (11) and when viewed from the front operation part 10 side, there is a possibility that the appearance is not seen. However, by attaching the filler 9 having a height corresponding to the gap length like the bone drop-in stove, it does not become too large and the appearance of the drop-in stove is not lost. In addition, even if this gap H3 changes with the said combination, when the gap | interval H3 needs to respond | correspond to various heights, the filler 9 of the height length corresponding to it can be attached, and it can cope with various changes in a beautiful way. have.

As described above, the drop-in furnace of the present invention can cope with the height of various types of worktops, while the main components such as the furnace body 1 and the internal burners 61, 62, and 63 can be used as they are. Since the number can be minimized, assembly is not cumbersome and the labor of parts management is not necessary. In addition, instead of the screws 99a and 99b, the locking means by the hole portion and the engaging piece can be formed in the hanging frame 2 and the working body 1. Although not shown, the side walls of the hanging frame 2 and the main body 1 may be fitted to each other and fixed by these locking means. By employing the various engagement methods in this manner, the hanging frame 20 and the working furnace body 1 can be freely configured.

Hereinafter, the drop in hearth of the present invention will be further described with reference to FIGS. 10 to 17. In Fig. 10, the burner 61 has a burner mixing tube 61a and a main body portion integrally formed, and a plurality of holes 61e through which the inner and outer portions of the main body 61b are connected are formed in the circumferential direction. The burner cap 53 is covered with an upper portion of the burner 61. The burner cap 53 is formed in a substantially disk shape, and a cylindrical void is formed therein. At the lower side of the outer periphery 53a of the burner cap 53, a plurality of bladder-shaped protrusions are formed in the circumferential direction, and the burner 61 is formed along a passage formed between the upper end portion 61b of the burner 61. Is formed with a spark hole (55). In addition, the upper part of the burner cap 53 is provided with the ventilation hole 55a connected to the internal space | gap. A ring-shaped covering 70 is fitted to the outer circumferential portion 61c of the burner 61 main body portion, and the outer circumferential portion thereof is placed so as to cover the hole portion 43 of the auxiliary upper plate 4. By the outside fitting of this covering 70, the clearance gap between the hole part 34 of the upper plate 3, and the outer periphery part 61c of a burner is hidden when viewed from the tricot 51 side. In addition, the hole portion 43 of the auxiliary upper plate 4 may be set to a size substantially close to the outer circumferential portion 61c of the burner 61 without using the covering 70. In addition, the cutout portion 48a cut out at the lower side is formed in the outer peripheral subsurface lower wall 48 of the auxiliary upper plate 4 and placed on the upper plate 3 by the legs 48b, so that the mounting portion of the upper plate 3 ( 38) A gap C is formed between the upper surface and the cutout 48a. That is, a gap is formed between the upper plate 3 in the outer circumference of the auxiliary upper plate 4, and is connected to the gap between the upper plate 3 and the auxiliary upper plate 4 and the open hole of the burner formed in the upper plate 3. It works. The cutout portion 48a is formed on the inner side of the outer periphery lower wall 48, on the front manipulation portion 10 side, and on both the left and right sides, but is not formed on the semi-manipulation portion side (see Fig. 11). This is because the exhaust is prevented from entering between the auxiliary upper plate 4 and the upper plate 3 when the pan is placed above the exhaust port 36a of the grill portion 85.

Therefore, the following ventilation passage is formed between the inner space of the furnace case 100 and the upper side of the counter top 7. That is, in the internal space of the furnace case 100, the gap A between the upper plate hole portion 34 and the outer peripheral portion 61c of the burner, and the gap B between the auxiliary upper plate 4 and the upper surface of the upper plate 3. ), The gap C of the cutout portion 48a of the auxiliary upper plate 4, and the lower gap 51h (D) of the frame 51f in the trivet 51 and the circumferential wall 32 of the upper plate 3. An aeration passage is formed which is connected to the upper side of the counter top 7 via the gap E of the frame body 51f of the tricycle.

Thus, by the combustion of the burner 61, the air in the furnace case 100 is discharged to the counter top 7 side through the ventilation passage. The top plate 3 and the auxiliary top plate 4 are cooled by this flow of air, and furthermore, the counter top 7 is also cooled. The upper plate 3 and the hanging frame body 2, which are connected to the upper plate 3, are heated by the radiant heat of the flame radiated from the flame hole, but the auxiliary upper plate 4 is blocked on the upper plate 3 side. In addition, the circumferential wall 32 of the upper plate 3 is also blocked by the frames 51f and 52f of the trivets 51 and 52, and the upper plate 3 and the like are cooled by the flow of air in the ventilation passage. Therefore, the temperature rise of the upper plate 3 and the hanging frame 2 is suppressed, and overheating of the counter top 7 is prevented.

In FIG. 11, the burner cap 54 is covered with the upper part of the burner 63, and the flame hole part 56 is formed. Moreover, the cover 63b which covers this from the upper side is provided in the housing upper part which surrounds the burner mixing pipe 63a, and the covering 71 is put in the lower end 63c of the outer periphery. The covering portion 71 covers the hole portion 44 of the auxiliary upper plate 4, and at the same time, the hole portion 35 of the upper plate 3 is also hidden when viewed from the tricot 52 side. Moreover, the lower side of the burner 63 is provided with the duct 87 for discharge-guiding the exhaust from the grill part 85 which is the baking chamber arrange | positioned under the upper plate 3 to the upper side of the counter top 7, The outlet 87a of the 87 faces the open hole 36b of the upper plate 3, and the trivet 52 covers the upper side of the open hole 36b. A mesh-shaped guard 88 is placed on the upper plate 3 so as to cover the openings 36a, 36b, and 36c.

Therefore, the following ventilation passage is formed between the inner space of the furnace case 100 and the upper side of the counter top 7. That is, the gap G between the outer circumferential portion 71a of the covering 71 and the circumferential wall 47 of the auxiliary upper plate 4 and the upper space H of the guard 88 in the inner space of the furnace case 100. A vent passage is connected to the upper side of the counter top 7 through (). Thus, the air in the furnace case 100 is discharged to the counter top 7 side through the vent passage by combustion of the burner 63. The top plate 3 and the auxiliary top plate 4 are cooled by this flow of air, and the counter top 7 is also cooled. In addition, a part of this flow passes through the upper part of the covering 71 from the clearance gap G between the outer peripheral part 71a of the covering 71, and the circumferential wall 47 of the auxiliary upper plate 4, and burner 63 Secondary air is supplied to the combustion chamber to keep the burner in good condition. The upper plate 3 and the suspending frame body 2 provided in succession thereof are heated by the radiant heat of the flame radiated from the flame hole portion, but the upper plate 3 is prevented by the auxiliary upper plate 4 and the frame body 52f. Blocked with respect to the side, the upper plate 3 is cooled by the air flow in the vent passage. Therefore, the temperature rise of the upper plate 3 and the suspension frame 2 is suppressed, and overheating of the counter top 7 is prevented. In addition, when the grill part 85 is used, the exhaust is discharged upward from the duct 87 via the guard 88. However, even if a pot or the like is placed in the upper trivet 52 of the outlet 87a of the duct 87, the exhaust is difficult to be discharged, but the trivet body is formed in the next path, that is, the gap 52h (L) of the trivet 52. It is easily discharged to the counter top 7 side via the gap M between 52f and the upper plate circumferential wall 32.

In the drop-in furnace of the present invention, all of these burners 61, 62, and 63 are used alone, and even if the pots are placed to cover the trivets 51 and 52, the respective ventilation passages described above. This is the distribution of air. In addition, since the lower triangular portions 51j and 52j are formed on the frame pieces 51f1 and 52f1 where the front tricycle 51 and the rear tricycle 52 are adjacent to each other and the frames 51f and 52f overlap with each other, the pan is a trivet ( 51 and 52, a gap is formed between these bottom upper edge portions 51j and 52j and the bottom of the pan, so that both trivets 51 and 52 are easily vented. Therefore, the above-mentioned ventilation passage which is vented to the upper part of the counter top 7 in the internal space of the furnace case 100, and the ventilation passage which exhausts from the grill part 85 to the half operation part side of the counter top 7 are formed, 9, the following ventilation passage is formed. That is, air flows in from the front operation part side of the counter top 7 and passes through the gap E between the upper plate circumferential wall 32 and the frame 51f, and through the gap 51h (D) of the auxiliary upper plate 4. Through the upper surface space I, and through the gap J between the bottom upper side portions 51j and 52j where the frames 51f and 52f overlap each other and the bottom of the pot, the upper surface space K of the auxiliary upper plate 4. Through) gap 52h (L). Then, the gap M between the upper plate circumferential wall 32 and the frame 52f is discharged to the upper portion of the counter top 7 on the side of the pot half operation portion.

Moreover, in this drop-in furnace, as shown to FIG. 3, FIG. 4, FIG. 5, etc., the ridge part in which the inner side (inner side surrounded by the circumference wall) of the upper plate 3 was raised in a part of the peripheral wall of the upper plate 3 is shown. 37 and a louver hole 37a whose lower end is opened are formed. Therefore, as shown in FIG. 16, the louver hole 37a through which the internal space of the furnace case 100 and the upper part of the upper plate 3 are connected becomes a ventilation hole. Therefore, the heated air in the inner space of the furnace case 100 does not stay inside (bottom) of the upper jaw portion 31 and is easily discharged to the outside, so that the side wall 21 of the upper plate 3 and the hanging frame 2 is closed. Since a rise in temperature, etc., is suppressed, overheating of the counter top 7 is also prevented in this case. As described above, the members of the upper plate 3 and the suspending frame body 2, which are subsequently connected to the upper plate 3, are suppressed from rising in temperature by the various ventilation passages and heat insulation described above, and the overheating of the counter top 7 is prevented.

10 and 11, the frames 51f and 52f of the trivets 51 and 52 are positioned between the burners 61 and 63 and the upper plate circumferential wall 32 and the burner ( The height is set so that the radiant heat in 61 and 63 is not directly radiated to the upper wall 3 circumferential wall 32. Therefore, the frames 51f and 52f function as heat shielding members, and the effect can be further enhanced while preventing the upper plate 3 from overheating.

In addition, in the above, even when the trivet 51 moves horizontally to the portion closest to the upper circumferential wall 32, the gap C of the cutout portion 48a of the auxiliary upper plate 4 → the lower gap of the trivet 51f (51h (D)) → The upper plate circumferential wall 32 and the triangular frame 51f are provided so that a ventilation passage connected to the upper side of the counter top E of the countertop 7 is secured. To this end, the upper peripheral wall 32 of the upper plate 3 on which the trivet 51 is placed is inclined in a widened state, and the outer circumferential side corner portion 390 of the end 39 is widened. The lower side of the trivet 51 frame 51f abuts). Therefore, even if the lower side of the frame 51f is in contact with the corner portion 390, a gap is necessarily formed between the outer surface of the upper frame piece 51f and the upper plate circumferential wall 32 opposite to the above. Aeration can be secured. In addition, the horizontal distance between the outermost end of the protrusion piece 51a of the trivet 51 and the opposing part of the circumferential wall 32 is L9, and the outer surface and the circumferential wall 32 of the frame 51f are set to L9. When the horizontal distance of the nearest part among opposing parts is L8, L9 <L8 may be sufficient. In this case, as shown in FIG. 3, FIG. 4, when the outer end part of the louver hole ridge part 37 and the said projection piece 51a opposes, the outer side of these ridge part 37 and the projection piece 51a. When the horizontal distance with the edge part is said L9, and the said projection piece 51a opposes in the middle of the ridges 37 and 37, the circumferential wall 32 and the projection piece 51a in the said intermediate part L9 is the horizontal distance from the outer end of the circuit. In addition, the relationship between the rear trivet 52 and the upper plate 3 is also configured as described above.

FIG. 12 shown next shows another embodiment by the modification of FIG. 10, and the through hole 70a which penetrates up and down in the covering 70 is formed. A plurality of through holes 70a are formed in the curved portion of the covering 70 in the circumferential direction. Therefore, in addition to the period gaps of FIGS. 10A, 10B, 10C, 10D, and 10E, the outer circumference of the burner in the following aeration passage, that is, the inner space of the furnace case 100 Through the gap A between the auxiliary upper plate 4 and the upper plate 3 through the gap A between the portion 61c and the upper plate hole portion 34, the flame hole portion 55 side from the through hole 70a. A vent passage is formed. In addition to the aeration of the aeration passage described above, the secondary air of the burner 61 is supplied by this aeration. In addition, the rear surface of the covering 70 or the rear surface of the auxiliary upper plate 4 functions as a guard that leads the secondary air to the flame hole portion 55.

13 shows another embodiment, the covering 74 is fitted to the outer periphery 61c of the burner and is fixed by the upper plate 3 to block the hole 34. Therefore, the following ventilation passage, that is, the ventilation passage leading from the clearance gap E to the flame hole portion 55 in the clearance gap E between the clearance gap 48 and the auxiliary top plate 4 and the covering 74. Is formed. By this ventilation, the secondary air of the burner 61 is supplied, while cooling the upper plate 3 in addition to the heat insulation of the upper plate 3 by the auxiliary upper plate 4 itself, and furthermore, the counter top 7 ) Heating is prevented. The covering 74 prevents the broth from entering the furnace case 100 as shown in FIG. 10 or FIG. 12. In addition, as long as the hole part 34 of the upper board 3 is sized so that the outer periphery part 61 of a burner may be closely fitted, the covering 74 may not be required.

14 which shows next shows another embodiment. The covering 72 has a cylindrical portion 72a formed in a cylindrical shape and its upper portion is radially curved to form a jaw portion 72b integrally, and the body portion 72a has an outer circumferential portion 61c of the burner. In addition to being fitted to the outside, it is fixed at the lower portion of the burner outer circumference 61d. The jaw-shaped portion 72b is formed between the auxiliary upper plate 4 and the upper plate 3 (vertical direction), and its outer diameter is the hole 43 of the auxiliary upper plate 4 and the upper plate 3, respectively. It is formed larger than the open hole of 34). Therefore, first, through the ventilation passage as follows, i.e., through the gap A between the outer periphery 61c of the burner and the top plate hole 34 in the inner space of the furnace case 100, the jaw portion 72b and the top plate are provided. Through the gap N of (3), through the gap B of the auxiliary upper plate 4 and the upper plate 3, and in the gap O between the auxiliary upper plate 4 and the jaw portion 72b. A vent passage leading to the portion 55 side is formed. By this ventilation, the secondary air of the burner 61 is supplied, while cooling the upper plate 3 in addition to the heat insulation of the upper plate 3 by the auxiliary upper plate 4 itself, and furthermore, the counter top ( Overheating of 7) is prevented. As shown in Fig. 10 or Fig. 12, the jaw portion 72b is prevented from entering into the upper plate 3 side of the soup, and the hole portion 43 of the auxiliary upper plate 4 has the jaw shape of the covering 72. Since it is smaller than the portion 72b, the back surface of the auxiliary upper plate 4 serves as a guard that leads the secondary air to the flame hole portion 55 side.

In addition to the above-described ventilation passage, the countertop 7 is formed by the ventilation passages of the gap A, the gap N, the gap B, the cutout 48a, the gap D, and the gap E. The overheating of the counter top 7 can be further prevented since the ventilation with the side can be better.

In FIG. 15 shown next, another embodiment is shown and a modification of the covering in FIG. 14 is shown. (A) of the figure shows a cross section, and (b) shows a state in which the auxiliary top plate is removed to look down from the covering 73 from the top. In this embodiment, as shown in FIG. (B), the periphery 73a, 73b, 73c was bent upward, and made the standing shape by making the outer shape of the covering 73 substantially triangular. Accordingly, the gap between the respective perimeters 73a, 73b, 73c of the covering 73 and the upper plate hole portion 34 is given and can be formed largely, and the ventilation of the gap is promoted while the respective perimeters are in the standing shape. As a result, the soup and the like are prevented from flowing down to the inside of the furnace case 100 in this gap. And the size of the hole 43 of the auxiliary upper piece 4 was made into the diameter smaller than the distance with respect to each circumference 73a-73c and the center of the burner 61. As shown in FIG. In this embodiment, a ventilation passage is formed as shown in FIG. 14, and overheating of the counter top 7 is prevented as described above.

17 shows another embodiment. Similarly to the above-described example, the auxiliary upper plate 400 is placed on the upper plate 3 by forming a vertical gap with the upper plate 3 even when the outer peripheral subsurface wall 480 is placed on the mounting unit 38. In addition, the notch 480a is formed in the outer peripheral subsurface wall 480 in the same manner as in the above example, so that the gap between the upper plate 3 and the upper plate 3 is formed. Also, in the drop-in furnace, various means may be employed as the means for forming the gap as in the above example. The auxiliary upper plate 400 is provided with an exhaust outlet 410 on which the outlet 87a of the duct 87 of the firing chamber is placed. The open hole periphery of the exhaust opening 410 is provided with a perforated wall around the open hole 411 over its entire circumference. The lower end abuts against the end portion 38b of the upper plate 3 to block the gap between the hole 36b and the exhaust outlet 411. In this drop-in furnace, exhaust from the firing chamber is prevented from entering between the auxiliary top plate 400 and the top plate 3 as in the above example.

As mentioned above, although the drop-in hearth of this invention was mentioned above, the structure shown in each embodiment can be used in arbitrary combinations, A design change etc. in the range of attention of this invention are also free of course.

As described above, according to the invention of claim 1, the top plate is prevented from being directly soiled by the soup or the like by the auxiliary top plate, so that the cleaning of the auxiliary top plate itself becomes easy. In addition, while the auxiliary upper plate is insulated to the upper plate, the temperature rise of the upper plate is suppressed by the ventilation of the ventilation passages, and the overheating of the counter top can be prevented. According to the invention of claim 2, since the space between the auxiliary top plate and the outer periphery of the burner is substantially closed, the broth and the like are prevented from entering the furnace case in addition to the one of claim 1. According to the invention described in claim 3, since the third gap is formed between the opening of the auxiliary top plate and the outer periphery of the burner, in addition to the one described in claim 1, a ventilation passage is newly formed, so that the burner burns well. Is done. According to the invention of claim 4, the firing chamber exhaust outlet is formed in the drop-in furnace, and is not formed in the portion formed along the exhaust outlet in the second gap formed between the auxiliary upper plate and the upper plate. Therefore, in addition to those described in Claims 1 to 3, even if a pot or the like is placed to block the exhaust outlet for the firing chamber, the combustion exhaust is prevented from entering the upper and lower gaps between the auxiliary upper plate and the upper plate. According to the invention of claim 5, the frame of the trivet forms a gap between the lower side and the upper plate, while a gap is formed between the frame outer surface of the trivet and the circumferential wall of the upper plate and is formed on the outside of the auxiliary upper plate. Since it was made to excrete, in addition to the thing of Claim 1 to Claim 4, overheating of a counter top can be prevented further.

According to the invention of claim 6, the top plate is prevented from being directly soiled by the soup or the like by the auxiliary top plate, and the auxiliary top plate itself can be easily cleaned. In addition, while the auxiliary top plate is insulated from the top plate, the temperature rise of the top plate is suppressed by the aeration of the ventilation passages through which the first gap and the second gap are connected, thereby preventing the countertop from overheating. According to the invention of claim 7, the exhaust port of the firing chamber is formed in the drop-in furnace, so that it is not formed in the site | part provided along this exhaust port among the 2nd clearance gap formed between the auxiliary upper plate and the upper plate. Therefore, even if a pot or the like is placed so as to block the exhaust port of the firing chamber, the combustion exhaust is prevented from entering the upper and lower gaps between the auxiliary upper plate and the upper plate. According to the invention of claim 8, the trivet frame forms a gap between the lower side and the upper plate, while a gap is formed between the outer surface of the tricycle and the peripheral wall of the upper plate to be disposed outside the auxiliary upper plate. Since it was made, the overheating of a counter top can be prevented further in addition to what was described in Claim 6 or 7. According to the invention of claim 9, since the upper and lower gaps between the periphery of the exhaust top of the auxiliary top plate and the periphery of the top of the top plate are blocked, the exhaust from the firing chamber is discharged from the firing chamber even when a heated object such as a pot is placed above the exhaust port for the firing chamber. Entering the gap with the top plate is prevented.
