Pressure bar device for maintenance-free energy-saving stove

Abstract

The invention relates to a pressure bar device for a maintenance-free energy-saving stove. As impurities such as oil sludge and water can enter the existing pressure bar for the energy-saving stove, great inconvenience is brought to chefs. Therefore, the pressure bar device for the maintenance-free energy-saving stove comprises an upwards and downwards movable pressure bar formed at a stove chamber and used for opening and closing gas, wherein the upper end of the pressure bar partially extends out of the stove chamber; a pressure bar cap capable of preventing impurities such as oil, mud and water from plugging the pressure bar is formed at the upper end of the pressure bar; the pressure bar cap is of a hollow cylindrical structure with a cover at the top end; a hollow tubular support rod is sleeved at the outer side of the pressure bar; the highest part of the support rod can not be exposed at the lower end of the pressure bar cap; the internal diameter of the support rod is greater than the external diameter of the pressure rod, and the internal diameter of the pressure rod cap is greater than the external diameter of the support rod; and the support rod is formed in a groove in the inner side of the edge of the stove chamber. The pressure bar device for the maintenance-free energy-saving stove has the advantages of good energy-saving effect, small environment pollution, capability of preventing the impurities such as oil, mud and water from plugging the telescopic pressure bar, and the like, thereby bringing great convenience to the chefs.

Description

technical field [0001] The invention relates to a pressing bar device, in particular to a pressing bar device for a maintenance-free and energy-saving stove. Background technique [0002] At present, the vast majority of hotels, guesthouses, and canteens in my country still use ordinary conventional stoves. The stove body is mostly made of refractory bricks and refractory cement, which has low combustion efficiency, large heat loss, and great environmental pollution. Short life. In addition, there is a kind of stove that uses an iron hearth. The iron hearth is used to place the pot body, the burner head that can pass through the gas is provided under the hearth, and there is a flue opening on the periphery of the iron hearth. However, when people use it, especially when cooking At that time, when the pot leaves the furnace, the fire is still burning, which causes a great waste of energy, and the heat loss is large, which causes great environmental pollution. In addition, im...

In addition, there is a kind of stove that uses an iron hearth. The iron hearth is used to place the pot body, the burner head that can pass through the gas is provided under the hearth, and there is a flue opening on the periphery of the iron hearth. However, when people use it, especially when cooking At the same time, when the pot leaves the furnace, the fire is still burning, resulting in a great waste of energy, and the heat loss is large, which causes great environmental pollution.

In addition, the pressure rod of the existing energy-saving stove is easy to enter impurities such as oil sludge and water, which brings a lot of inconvenience to the chefs.
