Description

Stove heat shield

Technical Field

The utility model belongs to the cooking utensils field, concretely relates to cooking utensils separate heat exchanger.

Background

In the actual use process of the existing gas stove, because a pot is placed on a pot support to heat, and a certain space interval is formed between the pot and a burner, the heat energy generated by gas combustion is used for heating the pot, and a considerable part of the heat energy is dissipated to the surrounding environment, so that energy waste is caused.

In order to solve the technical problems, for example, the chinese utility model patent "an energy-collecting gas cooker", the patent number of which is ZL201420463304.7 (publication number is CN204042984U), discloses an energy-collecting gas cooker, which comprises a bottom shell, a panel, a liquid receiving disc and a burner, wherein the liquid receiving disc is arranged on a mounting hole on the panel; the energy-gathering pot support comprises an inverted frustum-shaped energy-gathering cover with an upper opening and a lower opening, a cylindrical supporting seat and pot supporting legs arranged on the energy-gathering cover, wherein a plurality of notches are formed in the lower end of the cylindrical supporting seat and penetrate through the cylindrical supporting seat; the cylindrical supporting seat between two adjacent notches forms a supporting leg; a secondary air channel is formed by a gap between the lower opening end of the inverted frustum-shaped energy-gathering cover and the top of the circular boss, and the supporting legs are matched with the annular disc body. Although the energy gathering ring structure can reduce the consumption of heat energy to a certain extent, the gas stove is generally placed at a ventilation position of a kitchen, and when wind force in an external environment is large, the combustion flame of the gas stove can be unstable in swinging, and sometimes even flameout can be caused.

In order to solve the technical problem, for example, in the chinese utility model patent "a heat shield for kitchen and a kitchen range using the same", the patent number is ZL201721665905.6 (the publication number is CN 208222589U) discloses a heat shield for kitchen, which comprises an annular cover body, and is characterized in that: the cover body is the bilayer structure who constitutes by upper cover and lower floor's cover, upper cover and lower floor cover between be formed with the cavity, the upper surface of upper cover is fixed with along the pot stabilizer blade of circumference interval arrangement. Although the heat shield can achieve the purpose of improving the gas utilization rate to a certain extent, the double-layer shield body is directly contacted with the outside cold air, so that heat is easily taken away, and the possibility of outward heat dissipation is increased.

Preferably, the first cover, the second cover and the first supporting leg are an integral piece.

The second cover body can adopt squarely, also can adopt the ring shape, specifically, the second cover body is including being the annular diapire and the rampart that outwards and upwards slope gradually extended from the periphery edge of diapire, the interior border of diapire is the inboard border of the first cover body promptly, the topside border of rampart is the outside border of the first cover body promptly, diapire and rampart are hollow structure, and communicate and form the cavity.

In order to improve the heat efficiency and reduce the heat loss, the first cover body and the second cover body are concentrically arranged.

In order to reduce the contact area of the first cover body and the cooking top, the bottom of the first cover body is provided with second support legs extending downwards, and the number of the second support legs is at least two and the second support legs are arranged at intervals along the circumferential direction of the first cover body. Therefore, the heat dissipation of the first cover body to the kitchen range surface is reduced.

Compared with the prior art, the utility model discloses a second cover body is inside to have the cavity, and the existence of cavity can play good thermal-insulated effect to have the interval between the second cover body and the first cover body, this interval is used for gathering heat, can make the heat energy of radiation concentrate on the cavity all the time, can reduce the heat dissipation by the at utmost, the increasing of thermal efficiency.
