Abstract:
1. A cooking stove comprising: touch switches provided on a top plate covering a top surface of a cooking stove main body accommodating heating means, the touch switches allowing a user to give an instruction on activation of the heating means, the touch switches sensing an object that contacts or approaches the top surface of the top plate, wherein one of the touch switches is a heat quantity up switch for providing an instruction on an increase of the heat quantity of the heating means and one of the touch switches is a heat quantity down switch for providing an instruction on a decrease of the heat quantity of the heating means; heat quantity varying means for varying the heat quantity of the heating means, among a plurality of preset levels; and heating control means which increases the heat quantity of the heating means by one level by using the heat quantity varying means when the heat quantity up switch shifts from a non-sensing state to a sensing state while the heating means is in operation, and reduces the heat quantity of the heating means by one level by using the heat quantity varying means when the heat quantity down switch shifts from the non-sensing state to the sensing state while the heating means is in operation, and wherein while the heating means is in operation, when the heat quantity up switch shifts from the non-sensing state to the sensing state and the sensing state is then maintained, the heat control means prohibits the heat quantity varying means from increasing the heat quantity of the heating means and when the heat quantity down switch shifts from the non-sensing state to the sensing state and the sensing state is then maintained, the heat control means continuously reduces the heat quantity of the heating means by a plurality of levels by using the heat quantity varying means.
