Description

  The present invention relates to a drop-in type stove that is installed in a state in which a stove body is dropped into a stove opening established at a counter top of a system kitchen such as an island kitchen.

  In the drop-in type stove, an outer bending flange is formed on the upper edge of the box-shaped stove body whose upper surface is open, and the outer bending flange is inserted into the stove opening in the countertop. The stove body is seated on the upper surface of the peripheral edge so that the stove body is supported by the counter top, and the stove body is covered from above with a top plate over the outer bending flange. Moreover, in order to prevent the bad influence to the combustion of a stove burner by the wind pressure at the time of opening and closing of the cabinet door under a countertop, the sealing property of the stove body is improved. Therefore, the primary combustion air cannot be sufficiently supplied to the burner mixing pipe in the stove body.

  Therefore, conventionally, according to Patent Documents 1 and 2, the top plate is configured to include a glass top plate main body and an air intake cover connected to the rear side of the top plate main body, It has been known to define a ventilation gap for covering the rear outer bending flange from above and supplying air into the stove body between the outer bending flange. In addition, in the thing of patent document 1, the air intake cover extends diagonally rearward and upward from the rear side part of the top plate main body, and in the thing described in patent document 2, the air intake cover is rearward from the rear side part of the top plate main body. The rear end portion of the air intake cover that is located rearward of the rear end position of the outer bending flange at the rear portion of the stove body is inclined rearwardly downward.

  By the way, there is a system kitchen called an island kitchen in which a system kitchen cabinet is arranged in the center of the kitchen. When a drop-in stove is installed on the counter top of the island kitchen, there is no wall behind the stove installation portion of the counter top, so the stove can be seen from the rear. Therefore, in the thing of patent document 1, the part of the ventilation gap of the back side of the air intake cover which extends diagonally rearward upwards becomes completely visible from the rear, thereby impairing the appearance. On the other hand, in the thing of patent document 2, since the rear-end part of a horizontal air intake cover inclines back backwards, even if it sees from back, an air gap is not conspicuous and the appearance becomes favorable.

  However, in the thing of patent document 2, when a spill is applied to an air intake cover, the spill will flow from the rear end part of the air intake cover inclined downward to the counter top, causing the following problems. In other words, since the rear end of the intake cover is located behind the rear end position of the outer bent flange at the rear of the stove body, the countertop portion adjacent to the rear end of the outer bent flange is below the rear end of the intake cover. Even if it is hidden and boiled in this part, it is difficult to notice. Even if it is noticed, the rear end of the air intake cover is in the way, and it is difficult to wipe off the boiled up in this part. If the spillage accumulates to a certain extent, it becomes difficult for air to flow into the ventilation gap, resulting in poor combustion.

And a swash plate unit, and wherein the position of the rear end of the inclined plate portion is equivalent to the position of the rear end of the rear portion of the outer bent flange of the stove body.

  According to the present invention, since the intake cover is provided with the inclined plate portion that is inclined rearward and downward, the ventilation gap becomes inconspicuous when viewed from the rear as in the case of the above-mentioned Patent Document 2. Therefore, even if a stove is installed on the countertop of the island kitchen, the appearance is improved. Further, since the position of the rear end of the inclined plate portion is equivalent to the position of the rear end of the outer bending flange at the rear portion of the stove body, the spilled portion that has flowed down from the inclined plate portion to the counter top is adjacent to the rear end of the outer bending flange. It is easy for the user to notice when it accumulates in the countertop portion, and furthermore, the spillage collected in this portion can be easily wiped off. Therefore, it is possible to prevent as much as possible that air is less likely to flow into the ventilation gap by leaving the spilled portion in the countertop portion adjacent to the rear end of the outer bending flange.

  Further, in the present invention, it is desirable to form an upward convex bead in the outer bending flange portion at the rear of the stove body. Here, when spilling the spillage that has flowed to the countertop portion adjacent to the rear end of the outer bending flange, a part of the spillage may be pushed up by the outer bending flange and enter the stove body. However, if the bead is formed, it is possible to prevent the spillage pushed up by the outer bending flange from entering the stove body by damming it with the bead, and further, the reinforcing effect of the outer bending flange can be obtained. .

Further, on the upper surface of the top plate main body 21, the virtues 6 formed by attaching a plurality of virtuosity claws 62 radially to the annular virtuosity frame 61 so as to surround the burner body 32 are placed.

  The rear side portion of the top plate main body 21 is located in front of the rear side wall portion 11 of the stove main body 1, and there is a gap between the rear side portion of the top plate main body 21 and the rear side wall portion 11 of the stove main body 1. Is secured. The intake cover 23 connected to the rear side portion of the top plate main body 21 is a member that covers the outer bending flange 12 at the rear portion of the stove body 1 from above and secures a ventilation gap 23 a between the outer bending flange 12. . The ventilation gap 23 a communicates with the inside of the stove main body 1 through a gap between the rear side portion of the top plate main body 21 and the rear side wall portion 11 of the stove main body 1. Therefore, air is supplied into the stove body 1 through the ventilation gap 23 a, and this air is sucked as primary air from the upstream end of the mixing pipe 31.

  With reference to FIG. 2, the air intake cover 23 of the present embodiment is made of an extruded product of metal such as aluminum, and a horizontal plate portion 231 extending horizontally rearward from the rear side portion of the top plate main body 21; And an inclined plate portion 232 inclined rearward and rearward of the horizontal plate portion 231. Note that the front end portion of the air intake cover 23 has an upper piece portion 233a slightly protruding forward from the front end of the horizontal plate portion 231, a hanging piece portion 233b hanging from the front end of the horizontal plate portion 231, and a lower end of the hanging side portion 233b. A groove portion 233 is formed which includes a lower piece portion 233c that bends and extends forward. The rear side portion of the top plate main body 21 is fitted with the silicone adhesive 233 d applied to the groove portion 233, and the intake cover 23 is fixed to the rear side portion of the top plate main body 21.

  The position of the rear end of the inclined plate portion 232 is equivalent to the position of the rear end of the outer bending flange 12 at the rear portion of the stove body 1. In the present embodiment, the rear end of the inclined plate portion 232 is located slightly rearward from the position of the rear end of the outer bent flange 12, but the rear end of the inclined plate portion 232 and the rear end of the outer bent flange 12 are Is less than 1/3 of the height H from the counter top CT at the rear end of the inclined plate portion 232, it accumulates at the portion of the counter top CT adjacent to the rear end of the outer bent flange 12. It is possible to see the spilled spillage from behind while standing by an adult, and it is possible to wipe this part without any trouble. This case is also included in the “equivalent”. In the present embodiment, H = 10.5 mm and L = 2.6 mm are set. The case where the position of the rear end of the outer bending flange 12 is located slightly rearward from the position of the rear end of the inclined plate portion 232 is also included in the above “equivalent”.

  A convex bead 12 a is formed on the outer bending flange 12 at the rear of the stove body 1. A bead is continuously formed not only on the outer bending flange 12 at the rear part of the stove body 1 but also on both lateral sides of the stove body 1 and the outer bending flange 12 at the front part, so that the outer bending flange 12 is formed on the entire circumference. You may make it reinforce over.

  According to the present embodiment, the horizontal plate portion 231 is provided on the intake cover 23, whereby a sense of unity between the top plate main body 21 and the intake cover 23 can be obtained. Further, since the inclined plate portion 232 inclined downward and rearward is provided at the rear portion of the intake cover 23, the ventilation gap 23a becomes inconspicuous even when viewed from the rear. Therefore, even if the stove is installed on the countertop CT of the island kitchen, the appearance is improved.

  Further, the spilled portion applied to the intake cover 23 flows down from the inclined plate portion 232 to the counter top CT without going around the lower surface of the intake cover 23. Then, the boiled spill flowing down to the countertop CT is prevented from entering the stove opening CTa by the packing 13 on the lower surface of the outer bending flange 12 at the rear of the stove body 1.

  Further, since the position of the rear end of the inclined plate portion 232 of the intake cover 23 is equivalent to the position of the rear end of the outer bending flange 12 at the rear portion of the stove body 1, the counter top CT adjacent to the rear end of the outer bending flange 12 can be used. It becomes easier to notice when spillage has accumulated in the part, and can prompt the user to clean. Then, boiled spillage accumulated in this portion can be easily wiped off without being disturbed by the inclined plate portion 232. Therefore, it is possible to prevent as much as possible that the counter top CT adjacent to the rear end of the outer bending flange 12 is left with spilled and it is difficult for air to flow into the ventilation gap 23a.

  Further, since the outer bending flange 12 at the rear portion of the stove body 1 is positioned above the counter top CT by the thickness of the packing 13, the spillage does not normally flow onto the outer bending flange 12. However, when wiping and cleaning the portion of the countertop CT adjacent to the rear end of the outer bending flange 12, the spillage may be pushed up onto the outer bending flange 12.

  Here, in this embodiment, since the bead 12a that protrudes upward is formed on the outer bending flange 12, the spilled spilled up on the outer bending flange 12 is dammed by the bead 12a and enters the stove body 1. In addition, the bead 12a is advantageous in that the reinforcing effect of the outer bending flange 12 can be obtained.

  As shown in the comparative example shown in FIG. 3, the horizontal plate portion 231 of the intake cover 23 is extended rearward to a position equivalent to the rear end position of the outer bending flange 12 at the rear portion of the stove body 1, and the rear portion of the horizontal plate portion 231 is extended. It is also conceivable to form a bent portion 234 that bends downward at the end. However, in this case, when viewed from the rear, the height of the intake cover 23 from the counter top CT is emphasized by the presence of the bent portion 234, which gives a visual impression that the intake cover 23 is thick. On the other hand, according to the present embodiment, since the height of the intake cover 23 from the counter top CT is gradually lowered by the inclined plate portion 232, a visual impression that the intake cover 23 is thin can be given and the appearance is good. become.

  As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to this. For example, in the above embodiment, the air intake cover 23 is fixed to the rear side of the top plate main body 21 in the groove 233 formed at the front end thereof, but the upper piece 233a of the groove 233 is omitted and the lower piece 233c is You may adhere and fix to the lower surface of the rear side of the top plate main body 21. In this case, if the top surface of the top plate main body 21 and the top surface of the horizontal plate portion 231 of the intake cover 23 are flush with each other, it is possible to obtain a stronger sense of unity between the top plate main body 21 and the intake cover 23, which is advantageous. is there.
