Description

Kitchen gas energy-saving steam machine

[technical field]

The utility model relates to a kind of kitchen gas energy-saving steam machine, belongs to the field of the machinery that produces steam.

[background technology]

Energy scarcity is the key factor of restriction economic development, and domestic energy waste is serious, and building a conservation-minded society becomes long-term fundamental state policy of country.Catering trade is the highly energy-consuming industry, a large amount of heat energy be need consume every day and cooking and dish are used for, the Fuel Consumption of the logical steamer of one Daepori is equivalent to 3-4 common frying pan, because of its service time long, need uninterrupted the unlatching every day, for up to 8-14 hour, and can not change according to the variation of article in the cabinet when using, the empty phenomenon of burning is serious.The food and drink kitchen mostly adopts the mode of the water generates steam in the direct heating kettle of stove to come cooking at present, because iron pan is big, heat exchange area is little, certainly will cause and heat up slowly, and the thermal efficiency is low, and energy waste is serious; When intermittently using, in order to keep normal duty, meeting waste fuel in vain increases operating cost, enlarged link environment pollution and energy waste.

[summary of the invention]

At the deficiencies in the prior art part, the utility model aims to provide a kind of energy instantaneously producing steam, the kitchen gas energy-saving steam machine that cuts down the consumption of energy.

For achieving the above object, the utility model kitchen gas energy-saving steam machine, comprise shell, heater, its enclosure sets gradually fuel gas buring chamber, water cavity, vapor chamber, flue gas chamber from bottom to top, water cavity and vapor chamber are one, are tightly connected between fuel gas buring chamber and the water cavity and between vapor chamber and the flue gas chamber, have many curved overcurrent heat build-up pipes in the water cavity, overcurrent heat build-up pipe bottom inlet is communicated with the fuel gas buring chamber, and the top outlet is communicated with the flue gas chamber.

The beneficial effects of the utility model are: repeatedly utilize waste heat, significantly improve the thermal efficiency, its gas thermal efficiency can improve the heat energy utilization rate greatly up to 95%, reduces the use amount of fuel, reduces the cost of operation and the waste of the energy.

[description of drawings]

Below in conjunction with drawings and Examples to this practical further specifying.

Fig. 1 is a kind of internal structure schematic diagram of the present utility model;

Fig. 2 is a kind of structural representation of water supply tank in the utility model;

Fig. 3 is a kind of perspective view of the present utility model.

Among the figure, 1-shell, 2-vapor chamber, 3-water cavity, 4-fuel gas buring chamber, 5-overcurrent heat build-up pipe, 6-overtemperature protection probe, 7-flue gas chamber, 8-fire row, 9-ball float, 10-water supply tank, 11-steam (vapor) outlet, 12-steam overvoltage protection, the oral siphon of 13-water supply tank, 14-water level limitation valve.

[specific embodiment]

As shown in the figure, the kitchen gas energy-saving steam machine of present embodiment, comprise shell 1, heater, its shell 1 inside sets gradually fuel gas buring chamber 4, water cavity 3, vapor chamber 2, flue gas chamber 7 from bottom to top, water cavity 3 is an one with vapor chamber 2, is tightly connected between fuel gas buring chamber 4 and the water cavity 3 and between vapor chamber 2 and the flue gas chamber 7, has many curved overcurrent heat build-up pipes 5 in the water cavity 3, overcurrent heat build-up pipe 5 bottoms inlet is communicated with fuel gas buring chamber 4, and the top outlet is communicated with flue gas chamber 7.

Behind the fire row 8 who lights fuel gas buring chamber 4, the heat that burning produces on the one hand from the bottom directly and the water generation heat exchange the water cavity 3, on the other hand by negative pressure air exhauster suction overcurrent heat build-up pipe 5, by the surface of pipe and the water generation heat exchange in the water cavity 3, made full use of the heat in the flue gas that produces after the burning, increase the number of times of heat exchange, improved the thermal efficiency.

Preferred overcurrent heat build-up pipe 5 is arc or S shape in water cavity 3,, be linear in vapor chamber 2, both increased the area with water generation heat exchange, reduced the heat exchange area with steam again, further reach the energy-conservation purpose of putting forward effect.

In addition, steam engine also not influencing the position that steam produces, is provided with the water supply tank 10 that can control water level, and its below delivery port connects the water inlet of water cavity 3, and water supply tank 10 water inlets are positioned at the top; Be provided with water level inductor in the water supply tank, select for use ball float 9 in the present embodiment, also can select the electronics water level probe for use as water level inductor.Water enters water supply tank 10 from the water level limitation valve 14 of water inlet, when ball float 9 is sensed the water that enters and has been surpassed certain limit, water level limitation valve 14 is closed, when ball float 9 is sensed water level and is lower than certain value, water level limitation valve 14 will be opened again, control the water yield in the water cavity 3 simply, the steam energy source is constantly produced; And, the oral siphon 13 of water supply tank 10 is by flue gas chamber 7, the water pipe that is positioned at flue gas chamber 7 is curved shape, makes water elder generation and flue gas generation heat exchange in entering water supply tank 10, and curved shape has strengthened exchange area, thereby the water temperature that enters into water cavity 3 is increased to more than 50 ℃, the temperature difference of needed water temperature has shortened the heat time heating time in water cavity 3 when having reduced with generation steam, has saved the consumption of combustion gas, accelerate the steam generation time, thereby better guaranteed the continuity of steam.
