Abstract
A waste heat recovery kettle for a gas cooker comprises a kettle body and a water inlet, wherein the kettle body is an annular cavity body, and the water inlet is formed in an outer side wall of the kettle body. The kettle is matched with the existing various gas cookers for use; the gas utilization ratio can be effectively increased; gas for heating water is saved; the temperature rise around the gas cooker is reduced; pot support feet are protected; and the common fault that open fire of the gas cooker is scorching is eliminated. The gas utilization ratio is above 85% after improvement. In addition, a manufacturer can conceal the waste heat recovery kettle in the desktop cooker and the embedded cooker to replace a pot bracket and a pot bracket tray, so that the cooker is more energy-saving; and the service life of the gas cooker can be prolonged greatly.
Description
Technical field
The utility model belongs to the reusing of energy source technical field, relates in particular to a kind of gas kitchen ranges Waste Heat Recovery kettle in catering industry, the individual family.
Background technology
At present, the gas kitchen ranges of each manufacturer production on the market is paid attention to the bottom of a pan degree of being heated evenly more, and the flare energy-conservation aspect such as angle that fires considers, to pay attention to pan bracket, the thickening of pan bracket pallet thickness durable etc. more.But, use several years by the phenomenon that pan bracket is blown, the pan bracket pallet is burnt often occurring; Use in that kitchen range are normal, the heat that the flame of gas kitchen ranges burner ejection produces is most of is utilized by pot, also has a lot of heats to pass to surrounding space in the heat radiation mode and be wasted.
Testing result according to national gas appliance quality supervision and test center shows, the thermal efficiency of the desk-top gas-cooker of China is commonly 55%～58% at present, the thermal efficiency of embedded gas-cooker is commonly 52%～55%, the thermal efficiency surpasses 60% gas kitchen ranges ratio less than 1%, and it is very far away that this present situation and the popularity rate of the economical gas tool of developed countries nearly 80% such as Japan, the U.S. are compared gap.
Summary of the invention
At the problems referred to above, the utility model has designed a kind of gas kitchen ranges Waste Heat Recovery kettle, its purpose is: the gas kitchen ranges pan bracket, the pan bracket pallet, replace with the Waste Heat Recovery kettle, the heat of gas kitchen ranges waste is absorbed by kettle like this, thereby for life, produce hot water is provided, reaches the service efficiency that improves combustion gas, prolongs the kitchen range purpose in service life.
The utility model technical solution:
Gas kitchen ranges Waste Heat Recovery kettle is characterized in that: described kettle comprises kettle body and water inlet, and described kettle body is designed to the annular cavity body, and described water inlet is arranged on the external sidewall of kettle.
Preferably, be provided with pot leg and heat absorbing sheet above the described kettle body.
Preferably, described kettle external surface and bottom are equipped with the heat insulation outer cover of fire-retardant heat insulation.
Preferably, described kettle body and heat absorbing sheet contact position upper end is provided with the water conservancy diversion slope.
Preferably, described kettle body inside lower end is provided with auxiliary air compensation water conservancy diversion slope.
Preferably, described kettle external surface is provided with handle.
Preferably, described kettle external surface is provided with delivery port.
The quantity of described pot leg is at least three.
Preferably, the quantity of described leg is five.
Preferably, described pot leg and heat absorbing sheet place straight line extended line do not overlap with the center of circle, and described heat absorbing sheet place face is not vertical mutually with ring body surface.Described pot leg is vertical with the kettle body.
The beneficial effects of the utility model:
The utility model is used with existing various gas kitchen ranges, more can effectively improve the combustion gas utilization rate, has saved the used combustion gas of manufacture hot water, has also protected a pot leg when reducing gas kitchen ranges temperature rise on every side, has eliminated the roasting people's of gas kitchen ranges naked light common fault.The utility model improves back combustion gas utilization rate more than 85%.Simultaneously manufacturer can be hidden in table type kitchen range to the Waste Heat Recovery kettle design, and built-in type cooker inside replaces pan bracket, pan bracket pallet, makes kitchen range more energy-conservation, and can prolong gas kitchen ranges service life greatly.
Description of drawings
Fig. 1: the utility model vertical view.
Fig. 2: the utility model left view.
Fig. 3: the utility model cutaway view.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Kettle body as shown in Figure 1 to Figure 3,1, burner, 2, the pot leg, 3, heat absorbing sheet, 4, the heat insulation outer cover of fire-retardant heat insulation, 5, heat absorbing sheet water conservancy diversion slope, 6, auxiliary air compensation water conservancy diversion slope, 7.
As shown in Figure 1, pot leg 2 is passed to the kettle body to heat for supporting the use of pot body and gas kitchen ranges.
Heat absorbing sheet 3 absorbs the heat of gas flame flame envelopes, absorbs the heat of the external light radiation of flame, absorbs the outer field heat of combustion gas thermal current that jet flames forms, and then heat is passed to water in the kettle body in the mode of heat exchange.
The heat insulation outer cover 4 of fire-retardant heat insulation, shown in the maximum cylindrical of Fig. 1, effect is to prevent the heat of kettle to the outside and bottom heat radiation, effectively store heat reduces the temperature rise of gas kitchen ranges periphery simultaneously.
Heat absorbing sheet water conservancy diversion slope 5 shown in Fig. 3 cutaway view, allows form one spiralling cylinder air-flow by the thermal current after the heat absorbing sheet heat absorption, heats for bottom of pot body and side again, rather than allows thermal current diffuse in the air to waste.Pot leg and heat absorbing sheet extended line can not overlap with the center of circle, and both kettle pot leg and heat absorbing sheet will unify all sideling that an angle is placed on above the kettle, and large tracts of land absorbs heat can to allow pot leg and heat absorbing sheet have more like this.
Auxiliary air compensation water conservancy diversion slope 6, shown in Fig. 3 cutaway view, water conservancy diversion slope, kettle bottom can replenish more air, allows the more abundant burning of combustion gas, reduces noxious gas emission, environmental protection more.
Kettle body 7 is that general gas kitchen range pan bracket and pallet effectively make up, shown in Fig. 3 cutaway view, annular cavity is filled with water and partially absorbs the heat that kettle pot leg, heat absorbing sheet transmit, the external light radiation heat of flame and the outer heat of combustion gas hot-fluid that absorbs jet flames formation are the main bodys that reclaims heat.
Embodiment 1:
When using the utility model in family, after the adding suitable quantity of water, with first wife's gas kitchen ranges pan bracket, the pan bracket pallet is taken away, and puts the Waste Heat Recovery kettle, passes burner 1 in the kettle body 7, when the needs cooking, and the heat that kettle is wasted before absorbing and improving.Cooking after finishing is closed combustion gas, kettle is taken off down hot water get final product.If use kitchen range for a long time, handle may scald one's hand, and please carefully carries out pouring after kitchen range use end.
Embodiment 2:
When using the utility model at the restaurant, owing to will use kitchen range for a long time, water pipe can be installed respectively on water inlet and delivery port.When needs hot water, the valve that only need open outlet conduit just can use hot water.The valve of opening inlet channel can constantly add water to kettle, will constantly have hot water to use like this.
To sum up, it can effectively alleviate kitchen use hot water problem.The utility model is regenerated to the manufacturing kitchen range of gas kitchen ranges simultaneously, will have significantly to promote aspect environmental protection and energy saving.
