Abstract

The utility model discloses a heat accumulating type gas stove relating to the technical field of gas stoves and solving the problems of large heat loss and low efficiency of the existing gas stove. The heat accumulating type gas stove comprises a mixing chamber, a combustion head, a hearth, a smoke runner and a heat accumulating radiation plate, and is characterized in that the mixing chamber is communicated with a spray nozzle on the combustion head, and the combustion head is arranged in the hearth enclosed by a stove ring and a stove bottom, the hearth is provided with a smoke leading-out opening, and the smoke runner is arranged between the combustion head and the smoke leading-out opening and is provided with the porous heat accumulating radiation plate. The heat accumulating type gas stove achieves the beneficial effects of less heat loss and high thermal efficiency.

Description

A kind of regenerative gas kitchen range

Technical field

The utility model relates to a kind of gas-cooker, more specifically says to relate to a kind of regenerative gas kitchen range.

Background technology

Existing gas-cooker generally all is open burning, and promptly the kitchen range dish exposes, and flame directly contacts with surrounding air during burning, does not have any retaining closed structure and heat reclamation device.The flare of general gas kitchen range is at random unable, and what active force the bottom of a pan is not almost had, and can be described as to edge away, and the heat energy utilization rate is extremely low, and fire is gone hither and thither along the bottom of a pan, and the flare that overflows along the pot limit is taken away a large amount of heats, and it is very serious to cause heat to run off; Because its design defect, the fuel of inside, combustion zone can not well contact with air, causes the incomplete combustion of fuel.So it is low and energy waste is more serious that common kitchen range use efficient.The most outstanding shortcoming of this combustion system is that heat loss is big, traces it to its cause: the one, owing to be open burning, only some is absorbed by the bottom of a pan in flame radiation, and all the other all are radiated in the environment.The 2nd, except radiation, flame and flue gas are passed to pot to heat with the form of heat convection, but flue gas leave the pot temperature also very high, be generally about 250 ℃, this part heat is wasted.Cooker commonly used at present is to be made by common metal, there is not any heat-insulation and heat-preservation structure, the heat that absorbs in being subjected to thermal process of cooker is used for heating the food except that part like this, remainder then looses in air by the cooker outer wall, Lang Fei heat also is very big in this way, someone once heated thermos flask water 12min with the immersion heater of a 1000W, heat the water of same volume then with the electric stove of same power, boiled 20 min that used of water as a result, than the former many power consumption 67 % why so reason be that the former heats that the keeping warmth space that is a sealing carries out, heat loss is very little, and latter's portion of hot amount does not obtain reclaiming and just is lost to environment and has suffered, and as seen the mode by accumulation of heat reclaims heat and can save a lot of energy.

Summary of the invention

The purpose of this utility model is: provide a kind of regenerative gas kitchen range simple in structure, to solve big, the inefficient problem of heat-energy losses of existing gas-cooker.The technical solution adopted in the utility model is: a kind of regenerative gas kitchen range, comprise mixing chamber, combustion head, the chamber of a kitchen range, flue gas flow channel and accumulation of heat radiant panel, be characterised in that: mixing chamber is communicated with the spray orifice on the combustion head, described combustion head is arranged in the chamber of a kitchen range that surrounds at the bottom of kitchen range circle, the kitchen range, the described chamber of a kitchen range has the flue gas outlet, forms flue gas flow channel between combustion head and the described flue gas outlet, blocks the accumulation of heat radiant panel that is provided with porous on the described flue gas flow channel.

Described kitchen range circle has the shape that can cooperate, form the sealing chamber of a kitchen range with the pot body.

The position of described flue gas outlet is lower than described combustion head.

Be provided with insulation material layer between at the bottom of described kitchen range circle and the kitchen range.

Described accumulation of heat radiant panel is higher than described flue gas outlet, is lower than described combustion head.

The tail gas that described flue gas outlet is drawn carries out heat exchange through heat exchanger and the air that will enter described mixing chamber.

Accumulation of heat radiant panel wherein, the preparation of employing exotic material, can stand 1200-1600 ℃ of Fire Radiation and sweep of gases for a long time, the flue gas that fuel combustion produces is through porous regenerator radiant panel hole, the heat part that flue gas has is absorbed by the porous regenerator radiant panel, temperature was raised to after ceramic wafer was heated, simultaneously heat radiation to being heated vessel, be heated the 20-40% that radiant heat that vessel absorb can account for gross energy, even it is higher, behind certain hour, be in poised state,, be heated vessel Yi Bian energy emission given Yi Bian absorb flue gas heat; Flue gas through the accumulation of heat radiant panel can enter heat exchanger, energy is transferred to combustion air, flue gas enters kitchen range circle heat exchanger then, the cold air of the energy exchange in the flue gas in the kitchen range circle, preheating enters the combustion air in the kitchen range kitchen range, discharge the gas outlet of last flue gas from the kitchen range circle, and at this moment oneself is very low for temperature, far below the flue-gas temperature of about 250 ℃ of common stoves.If flue gas enters external heat exchanger, then can directly drain, also can send into the kitchen range circle again and discharge.

The beneficial effect that the utility model reaches is: reclaim ember savings heat by using heat exchanger and accumulation of heat radiant panel, prevent thermal loss, the cold air of heating and combustion gas reaction, be used to improve flame temperature and realize completing combustion, reached the beneficial effect that heat runs off less, the thermal efficiency is high.

The specific embodiment

With reference to Fig. 1, Fig. 2, a kind of regenerative gas kitchen range, comprise mixing chamber, combustion head, the chamber of a kitchen range, flue gas flow channel and accumulation of heat radiant panel, comprise mixing chamber, the spray orifice 2 that described mixing chamber 1 is communicated with on the combustion head, described combustion head 3 is arranged in the burner hearth 6 that stove circle 4, furnace bottom 5 surround, described stove circle 4 has the shape that can cooperate, form closed furnace 6 with pot body, furnace bottom 5, described closed furnace 6 has flue gas outlet 61, forms flue gas flow channel between described combustion head 3 and the described flue gas outlet; Block the accumulation of heat radiant panel 7 that is provided with porous on the described flue gas flow channel.The position of described flue gas outlet 61 is lower than described combustion head 3, and described accumulation of heat radiant panel 7 is higher than described flue gas outlet 61, is lower than described combustion head 3.Described stove circle 4 and furnace bottom 5 are lined with insulation material layer.
