Description

  The present invention includes a stove body, a top plate that covers the top surface of the stove body, a stove burner that protrudes on the top plate through a burner opening provided in the top plate, and a burner opening that surrounds the burner opening on the top plate. It relates to a gas stove with five virtues.

  Conventionally, as this type of gas stove, a burner ring that is placed on the top plate in an extrapolated state with a stove burner has been provided, and the five virtue frames are externally fitted to the burner ring to center the five virtues. At the same time, there is known one in which a notch is formed in the outer peripheral portion of the burner ring, and a protrusion provided on the five virtues is engaged with the notch to prevent the five virtues from rotating (for example, see Patent Document 1).

  By the way, in order to reduce the number of parts and reduce the cost, an annular ridge corresponding to the above-described conventional burner ring in which an annular virtuosity frame of the virtues is fitted on the top plate at the peripheral edge of the burner opening. It may be possible to draw the part and omit burnering. In this case, if the notch is formed in the outer peripheral portion of the annular bulge portion, the simmering falls from the notch into the stove body.

  For this reason, it is desirable to form a groove that is recessed inward in the radial direction on the outer peripheral surface of the annular ridge, and to engage a protrusion provided on the five virtues in this groove to prevent the five virtues from rotating. According to this, even if the spilled oil flows into the groove, the spilled food does not fall into the stove body.

  However, this has been found to cause the following problems. That is, since the five virtue frame is mounted on the top plate in a state of being fitted around the annular ridge, the virtue frame is seated on the upper surface of the top plate portion adjacent to the radially outer end portion of the groove portion. As a result, boiled spillage that has flowed into the groove portion is blocked by the five virtue frames and collected in the groove portion, and the spilled portion tends to stick to the groove portion due to heat from the stove burner.

JP 2010-2104 A (paragraph 0014, FIG. 2)

  In view of the above points, an object of the present invention is to provide a gas stove that can prevent boiled-up sticking in the groove.

  In order to solve the above-mentioned problems, the present invention provides a stove body, a top plate that covers the top surface of the stove body, a burner that projects on the top plate through a burner opening provided in the top plate, and a burner on the top plate. A gas stove comprising a virtues placed so as to surround the opening for use, and is located on the top plate at the peripheral edge of the opening for the burner, and the annular bulging portion on which the virtually annular virtuosity frame is fitted is throttled In the outer peripheral surface of the annular bulging portion, a groove portion recessed radially inward is formed, and a protrusion provided on the five virtues is engaged with this groove portion to prevent the five virtues from rotating. In addition, the upper convex receiving seats projecting radially outward from the lower portions of the outer peripheral surface of the annular raised portion are not formed, and the five virtue frames are seated on these receiving seats. There is a gap between the top surface of the top plate adjacent to the radially outer edge and the five virtue frames. Characterized in that it is holding.

  According to the present invention, even if boiled spillage flows into the groove portion, the spilled portion of the groove portion is secured through the gap secured between the upper surface of the top plate portion adjacent to the radially outer end portion of the groove portion and the five virtue frames. Flows outward. Therefore, it is possible to effectively prevent boiled spillage from accumulating in the groove.

  By the way, in the conventional stove with a grill in which the grill is incorporated in the stove body, an exhaust guard that covers the exhaust port for the grill opened at the rear of the top plate is placed on the top plate. Here, if a raised portion that protrudes upward from the rear portion of the top plate is separated from the annular raised portion, and a plurality of exhaust holes for exhausting exhaust gas in the grill are formed in this raised portion, In addition to the annular raised portion corresponding to the burner ring, the raised portion corresponding to the conventional exhaust guard is integrally formed on the top plate, and the cost can be reduced by reducing the number of parts.

The perspective view of the gas stove of embodiment of this invention. The perspective view of the principal part of the state which lifted the five virtue of the gas stove of embodiment. Sectional drawing cut | disconnected by the III-III line | wire of FIG.

  Referring to FIG. 1, reference numeral 1 denotes a gas stove according to an embodiment of the present invention. The gas stove is provided with a box-shaped stove main body 2 having an open top surface, a sheet metal top plate 3 covering the top surface of the stove main body 2, and a pair of left and right burner openings 31, 31 provided on the top plate 3. A pair of left and right stove burners 4, 4 projecting on the plate 3, a grill 5 incorporated in the horizontal intermediate portion of the stove main body 2, and the burner openings 31, 31 are placed on the top plate 3 so as to surround them. And a pair of left and right virtues 6 and 6.

  As shown in FIG. 3, each stove burner 4 includes a mixing pipe 41 installed in the stove main body 2, and a burner body 42 that is integral with the mixing pipe 41 and protrudes above the top plate 3 through each burner opening 31. And a burner cap 43 placed on the burner body 42. The burner body 42 has an inner and outer double cylinder structure having an inner cylinder 42a and an outer cylinder 42b. The burner cap 43 has an annular shape, and a cylindrical portion 43 a that fits in the inner cylinder 42 a of the burner body 42 is provided on the inner periphery thereof. A cylindrical wall 43b seated on the upper end portion of the outer cylinder 42b of the burner body 42 is suspended from the outer peripheral portion of the lower surface of the burner cap 43, and a number of flames are provided on the cylindrical wall 43b with circumferential intervals. A hole 44 (see FIG. 2) is formed. In addition, a small flame hole 44a is formed in a portion of the cylindrical wall 43b located in the same orientation as the virtuosity claw 62 described later of the virtues 6 in order to prevent the flame from touching the virtuosity claws 62 and incomplete combustion. ing.

  On the burner cap 43, an annular secondary air guide 45 is provided between the upper surface of the burner cap 43 to define a secondary air ventilation gap. The stove burner 4 is additionally provided with a pan bottom temperature sensor 46 that contacts the bottom surface of the cooking container placed on the virtues 6, an ignition electrode 47, and a thermocouple 48.

  As clearly shown in FIGS. 2 and 3, the top plate 3 is formed with an annular raised portion 32 which is located at the peripheral edge portion of each burner opening 31 and protrudes upward. Grooves 33 that are recessed inward in the radial direction are formed at two front and rear portions of the outer circumferential surface of the annular ridge 32 that are separated from each other by a half circumference. In addition, a substantially rectangular raised portion 35 bulging upward, which is different from the annular raised portion 32, is formed at the rear portion of the top plate 3. A plurality of exhaust holes 35a are formed in the raised portion 35, and exhaust gas in the grill 5 is discharged from these exhaust holes 35a.

  In the conventional gas stove, a burner ring that is externally attached to the stove burner and an exhaust guard that covers the grill exhaust port at the rear of the top plate are placed on the top plate, but this corresponds to the burner ring as in this embodiment. By forming the annular raised portion 32 and the rectangular raised portion 35 corresponding to the exhaust guard integrally with the top plate 3 by drawing, the number of parts can be reduced and the cost can be reduced.

  Each of the five virtues 6 is composed of an annular five virtue frame 61 fitted on the annular raised portion 32 and a plurality of five virtue claws 62 fixed radially to the five virtue frame 61. Each of the five virtue claws 62 is formed in a substantially U shape having an upper side portion and a lower side portion, and is fixed to the five virtue frame 61 at the radially inner end of the lower side portion. In addition, a protrusion 63 that protrudes radially inward from the inner peripheral surface of the five virtue frame 61 is formed on the lower side portion of two predetermined five virtue claws 62 that are separated from each other by a half of the five virtue claws 62. The protrusion 63 engages with the groove 33 on the outer peripheral surface of the annular ridge 32.

  The five virtues 6 are centered by externally fitting the five virtue frames 61 to the annular raised portion 32, and by engaging the protrusions 63 with the groove portions 33, the five virtue claws 62 are positioned in the same orientation as the small flame holes 44a. The rotation is stopped at the phase of. Further, even if the spillage flows into the groove 33, the spillage does not fall into the stove body 2. However, when the virtuosity frame 61 is seated on the upper surface of the top plate portion adjacent to the radially outer end portion of the groove portion 33, the spilled portion that has flowed into the groove portion 33 is dammed up by the virtuosity frame 61 and collected in the groove portion 33. Boiled spillage is likely to stick to the groove 33 by heat from 4.

  Therefore, in the present embodiment, a plurality of locations where the groove portion 33 on the outer peripheral surface of the annular ridge portion 32 is not formed on the top plate 3 (specifically, two locations separated from the front groove portion 33 in one direction and the other in the circumferential direction). The upper receiving bases 34 projecting radially outward from the lower part of the rear groove part 33 (two places adjacent to both sides in the circumferential direction of the rear side) are drawn and formed on these receiving bases 34. The frame 61 is seated.

  According to this, a gap corresponding to the height of the receiving seat 34 is ensured between the upper surface of the top plate portion adjacent to the radially outer end portion of the groove portion 33 and the five virtue frame 61. For this reason, even if the spilled portion flows into the groove portion 33, the spilled portion flows out of the groove portion 33 through the gap. Therefore, it is possible to effectively prevent boiled spillage from collecting in the groove 33 and sticking.

  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 said embodiment, although the groove part 33 is formed in two places of the outer peripheral surface of the cyclic | annular protruding part 32, the formation part of the groove part 33 may be one place or three places or more. Moreover, in the said embodiment, although the protrusion 63 engaged with the groove part 33 is formed in the 5 virtue claw 62, it is also possible to form a protrusion in the 5 virtue frame 61.
