Description

  The present invention relates to a gas stove, and more particularly to an arrangement of a gas burner and the like accommodated in the gas stove.

  Conventionally, as this type of gas stove, for example, a gas stove 50 in which two gas burners 51 as shown in FIG. Both gas burners 51 are external flame type gas burners in which a flame blows outward, and heat cooking utensils such as a pot placed in the virtues 52. The gas burner 51 can be ignited, extinguished, and adjusted in thermal power by operating an operation knob 53 provided on the front surface of the gas stove 50.

  As shown in FIG. 10, a gas amount adjusting valve 55 for adjusting the amount of gas supplied to the gas burner 51 is disposed at a position corresponding to the operation knob 53 in the main body case 54 of the gas stove 50. . The gas introduction port 51 </ b> D of the gas burner 51 and the gas amount adjusting valve 55 are connected by a gas conduit 59. Further, a gas supply port 56 is disposed at the inner bottom and rear corner of the main body case 54, and the gas supply port 56 and the gas amount adjusting valve 55 are connected by a gas pipe 57 and introduced from the gas supply port 56. The gas is led to the burner 51.

  Separately from this, a gas stove provided with three or more gas burners 51 is also known.

  In a gas stove provided with a plurality of gas burners, it is necessary to form the gas pipe with a pipe slightly thicker than the gas conduit in order to enable simultaneous use of the plurality of gas burners. Further, since the gas stove 50 is configured to mechanically operate the gas amount adjustment valve 55 by the operation knob 53, the gas amount adjustment valve 55 needs to be connected to the operation knob 53, and the gas amount The adjustment valve 55 must be disposed in front of the gas stove 50 where the operation knob 53 is disposed. As a result, the gas pipe 57 connecting the gas supply port 56 and the gas amount adjusting valve 55 at the rear corner becomes longer. Then, it is necessary to make the gas pipe 57 thicker by the length of the gas pipe 57 so as not to cause a gas pressure loss. A pipe with a large diameter is harder to bend than a pipe with a small diameter, and the manufacturing cost increases.

  The objective of this invention is providing the gas stove which suppresses that gas piping becomes thick and can make the whole shape compact further.

  In order to achieve the above object, according to the first aspect of the present invention, a gas stove is provided with a plurality of large burners and a single small burner.

  In the present invention, since the electrically driven control valve is arranged on a straight region along the rear edge or side edge of the gas stove, it is relatively thick so that no gas pressure loss occurs even if gas is supplied to a plurality of burners. The length of the gas pipe can be shortened.

The invention according to claim 2 is the invention according to claim 1, wherein the small burner is arranged between two large burners arranged in the left-right direction among the large burners.
In order to put a cooking container of a certain size on the large burner, both large burners are arranged at a certain distance, and there is a space between the large burners. In the present invention, a small burner is disposed in the space between the two large burners. And since the control valve of these burners was arrange | positioned on the linear area | region along the rear edge or side edge of a gas stove, a gas stove can be made more compact. In particular, if the control valve is arranged at the rear edge of the gas stove instead of the cramped lateral space where three burners are arranged in the lateral direction, the space can be used effectively.

The invention according to claim 3 is the invention according to claim 1 or 2, wherein the gas inlets of the large burners are arranged so as to face each other.
In order to put a cooking container of a certain size on the large burner, both large burners are arranged at a certain distance, and there is a space between the large burners. In this invention, since the gas mixing pipes of both large burners are located in the space between the two large burners, the gas stove can be made more compact.

  According to a fourth aspect of the present invention, the gas stove is provided with a plurality of large burners, and the large burners are arranged at the left and right positions in the gas stove body. Then, the gas inlets of each large burner were arranged so as to face each other, and each electrically driven control valve for supplying gas to each burner was arranged on a linear region along the side edge of the gas stove.

  In the present invention, the large burners are arranged on the left and right, and the gas mixing pipes are arranged in the space between the large burners, so that the unoccupied increase in the width between the large burners is suppressed. Even if the control valve is linearly arranged on the right or left side edge, a burner, a control valve, or the like can be accommodated in a gas stove with a limited width.
