Air is supplied.

JP 2012-063093 A

  In the case of the gas stove as described above, when the spillage from the cooking container occurs, the broth enters the device body of the gas stove from the through hole. Since the broth that has entered the device main body is likely to break down when it is applied to a functional component stored in the device main body, it is conceivable to provide a spilled cover that receives the broth that has entered through the through-hole. However, even in this case, there is a possibility that the broth that has entered from the through-hole is well spilled and not guided to the cover, and if it adheres to the functional parts, there is a risk of failure.

  The present invention has been invented in view of the above-mentioned conventional problems, and the object of the present invention is that the broth that has entered the device body from the through-hole is guided to the spilled cover, and the broth is placed in the device body. It aims at providing the gas stove which suppresses adhering to the functional component accommodated.

  In order to solve the above-mentioned problem, a gas stove 1 according to claim 1 of the present invention has a flame port 25 provided in an annular shape in plan view, and a stove burner 2 having through-holes 23 and 33 penetrating vertically therein.

A gas stove 1 provided with a spilled cover 4 for receiving the infiltrated broth, the spilled cover 4 having a discharge hole 41 for discharging the received broth downward, and the burner receiving bar 6 of the stove burner 2 While being located under the through-holes 23 and 33, it is provided with the boiled soup guidance part 60 which guides the boiled juice which fell to the burner receiving crosspiece 6 to the spilled cover 4.

  The invention according to claim 2 is the invention according to claim 1, wherein the burner receiving bar 6 is a weir that surrounds a region where the through holes 23 and 33 of the stove burner 2 and the broth guiding part 60 overlap in plan view. While having the part 64, it has the discharge hole as the broth guidance part 60 in the said overlapping area | region, It is characterized by the above-mentioned.

  The invention according to claim 3 is the invention according to claim 2, wherein the burner receiving bar 6 is formed with a through-hole 65 penetrating vertically other than the discharge hole as the broth guiding portion 60, and the periphery of the through-hole 65 A through-hole weir portion 66 that protrudes upward is provided at the top.

  In the inventions according to claims 1 and 2, the burner receiving bar can be used as a broth receiver with a simple configuration in which the burner receiving bar is positioned below the through-hole of the stove burner. It is not necessary to provide a spilled body cover, and it is possible to prevent the soup from adhering to the functional components housed in the device main body while reducing the cost.

  In the invention which concerns on Claim 3, it is comprised so that the boiled juice received at the bottom part may not fall easily from a through-hole.

In the first embodiment, the flow restriction unit 50 is configured by a lower end edge of the burner receiving bar 6 that is located at a predetermined distance from the upper surface (receiving surface) that receives the boiled juice of the spilled cover 4. Yes. In the flow suppression unit 50, the burner receiving bar 6 is located between the through holes 23 and 33 and the discharge hole 41 in a plan view. The predetermined interval between the flow suppressing part 50 and the receiving surface of the spilled cover 4 is 3 mm in the first embodiment, but may be 2 mm or 4 mm, and preferably 2 mm or more. By providing the flow suppression part 50, the momentum of the flow of the received boiled soup is suppressed, and the excess boiled soup is suppressed from falling from a region (for example, an edge) other than the discharge hole 41 of the cover 4 Is done. Thereby, the functional components of the gas stove 1 to be protected by the spilled cover 4 (for example, the control unit, the driving means, etc., and particularly the electric device) are accurately protected.

  In the present invention, the burner receiving bar is located below the through-hole of the stove burner 2, and is provided with a broth guiding part 60 that guides boiled juice dropped on the burner receiving bar to the cover 4. In the first embodiment, as shown in FIGS. 4 and 5, the rear burner receiving bar 6 is positioned below the through-holes 23 and 33 of the small thermal power burner 2 c, and is a broth guiding part including a discharge hole. 60.

  Further, in the first embodiment, the rear burner receiving bar 6 includes a weir portion 64 that surrounds a region where the through holes 23 and 33 of the small heating burner 2c and the broth guiding portion 60 overlap in plan view, In the overlapping region, there is a broth guiding part 60 consisting of a discharge hole. The dam portion 64 is composed of a front dam 62 and a rear dam 63, and a left dam 64a and a right dam 64b that are erected from the left and right sides of the bottom 61.

  In the first embodiment, the burner receiving bar 6 on the rear side is formed with a through-hole 65 penetrating vertically in addition to the discharge hole as the broth guiding portion 60, and is raised upward at the periphery of the through-hole 65. A through-hole dam portion 66 is provided. The through-hole 65 is a maintenance hole for inserting a tool such as a screwdriver so that maintenance of parts arranged under the burner receiving bar 6 can be performed without removing the rear burner receiving bar 6 during maintenance. Is mentioned. By providing the through hole weir portion 66 at the periphery of the through hole 65, the soup received by the bottom portion 61 is configured not to easily fall from the through hole 65.

  In addition, it is not necessary to provide such a through-hole dam portion 66, and it is configured not to place a functional component or the like below the through-hole 65 so that no trouble occurs even if the broth falls from the through-hole 65. May be.

  In the present invention, the rear burner receiving bar 6 can be used as a broth receiver with a simple configuration in which the rear burner receiving bar 6 is simply positioned below the through-holes 23 and 33 of the small thermal power burner 2c. Therefore, it is not necessary to provide a separate spilled cover and the cost can be reduced.

  Moreover, although not shown in figure as 2nd Embodiment, it is good also as a guidance | induction part which forms the ditch | groove which guides to the discharge hole which discharges broth in the rear burner receiving crosspiece 6 and guides broth to the discharge hole.
