Pot ring

Abstract

A pot ring capable of utilizing heat wasted on a household gas stove to heat water comprises an inner shell (1) and an outer shell (2) which are both in a basin shape, the diameter of the inner shell (1) is smaller than that of the outer shell (2), the inner shell (1) and the outer shell (2) are basically the same in height, the inner shell (1) is arranged in the outer shell (2), and an upper bottom hole (3) and a lower bottom hole (4) which are larger than the outer diameter of a burner are formed in the centers of the bottom faces of the inner shell (1) and the outer shell (2). The opening edge of the upper bottom hole (3) is hermetically connected with the opening edge of the lower bottom hole (4); an annular space (5) with a closed bottom is formed between the outer shell (2) and the inner shell (1); enough water is added in the annular space (5), and when flames on the gas stove head heat the cookware, heat radiation outside the cookware and heat of high-temperature waste gas after combustion are conducted to the water in the annular space (5) through the inner shell (1), so that the temperature of the water is increased.

Description

Technical Field

[0001] The invention relates to a pot ring for supporting a pot on a household gas stove, in particular to a pot ring capable of absorbing and utilizing part of the heat lost on the gas stove. Background Art

[0002] As we all know, the pot rack on the burner of existing gas stoves merely supports the pot. Gas stoves are essential for daily household use. When the flame on the burner heats the pot, a significant amount of heat radiated and released from the high-temperature exhaust gases is wasted. This can cause indoor temperatures to rise in the summer, indirectly increasing air conditioning power consumption. However, hot water is essential for household life, and hot water is often obtained by consuming gas or electricity separately. This waste of heat is accompanied by the energy consumed to produce hot water, which in turn dissipates some heat, and sometimes requires electricity to cool the room. This creates a vicious cycle of energy loss and increases carbon emissions, exacerbating the ecological disaster caused by rising temperatures. Summary of the Invention

[0003] In order to make the most of the heat energy that is wasted on household gas stoves, the present invention provides a pot ring, which can not only replace the traditional pot ring and pot rack to support the pot, but also conveniently collect part of the heat dissipated by the burning flame on the burner outside the pot to heat water, thereby providing part of the hot water needs for daily family life.

[0004] The present invention provides a pot ring having the following structure, comprising: an inner shell and an outer shell, both of which are basin-shaped; the outer diameter of the inner shell is smaller than the inner diameter of the outer shell, and the heights thereof are substantially the same; the inner shell is positioned within the outer shell; an upper bottom hole and a lower bottom hole are centrally disposed on the bottom surfaces of the inner shell and the outer shell, each of which is larger than the outer diameter of the burner; the rim of the upper bottom hole is sealedly connected at the rim of the lower bottom hole to form the pot ring bottom hole; a closed-bottom annular space is formed between the outer shell and the inner shell; and a plurality of protrusions are disposed on the upper end of the inner shell, which are higher than the rim and protrude from the inner wall. When the pot ring is fitted onto the burner through the pot ring bottom hole and placed on a stove top, the annular space between the outer shell and the inner shell is filled with water, and a cooking or rice steaming pot is placed on the protrusions on the pot ring. When the burner is ignited, heat generated by heat radiation and hot air flow outside the pot is transferred through the inner shell to the water in the annular space, heating the water. Exhaust gases are discharged through the gaps between the protrusions.

[0005] The beneficial effect of the present invention is that it not only utilizes the heat that was originally wasted on household gas stoves to provide part of the hot water needed for family life, but also saves part of the gas or electricity consumed for hot water. At the same time, it alleviates the increase in indoor temperature of residents in summer and saves part of the electricity used for air conditioning, reduces living costs, and approaches low-carbon life to the greatest extent.
