Abstract

The utility model relates to a dry type absorption type refrigerator, which has the advantages of simple structure, convenient operation, high refrigerating efficiency and utilization of various energy sources. The utility model is composed of a heating device, a refrigerating plant, a steam box and a refrigeration container, wherein, the heating device comprises a burning chamber and a boiled water cylinder. The burning chamber can utilize various heat sources, such as domestic coal stoves, oil stoves, methane stoves, liquified gas stoves, electric stoves, firewood, etc. The heating device can also simultaneously boil water, heat water, steam and boil food, etc. The refrigerating plant adopts the anhydrous calcium chloride serving as absorption agent and the ammonia serving as refrigerant. The refrigerator is applicable for households and other occasions.

Description

An absorption-type refrigerator in combination with cooking

The utility model is the dry type absorption refrigerator.

As everyone knows, the refrigerator of people's use now has two classes: compressed steam refrigeration device and absorption refrigerator.The latter be owing to can adopt various energy resources, and attracting many researchers always.Occurred some different absorption refrigerators thus and patented.As DRPo54766 provide a kind of can electricity consumption or coal gas or kerosene make the dry type absorption refrigerator of thermal source.And for example USPat2041741 and USPat925039 provide and have adopted Mncl respectively ₂And NH ₄NO ₃Make the refrigerator of absorbent, what USPat1791515 and DRP553377 provided then is to adopt SrCl ₂Make the refrigerator of absorbent.Relevant therewith U.SPati705482, U.SPat1705484 etc. in addition.

Existing dry type absorption refrigerator, though can play the effect of refrigeration, owing to the deficiency of various degrees fails to be people institute practicability.For example can only limit to a certain in electricity, liquefied gas, the kerosene for the thermal source that refrigerator uses, and need special stove and accessory, its thermal source can only be used for refrigerator; The refrigerating efficiency that and for example has is low or cold-producing medium is expensive; There are high pressure in complicated or operation inconvenience of the structure that has or internal system and dangerous or the like.

The purpose of this utility model is, a kind of refrigerating efficiency height is provided, noiselessness, multipotency source, multi-functional, simple in structure, easy to operate, safe and reliable dry type absorption refrigerator.

The absorption multipotency refrigerator of dry type provided by the utility model as shown in Figure 1.It comprises the closed system that refrigerating plant, heating plant, food steamer, refrigerating box, refrigerating plant are made up of generator, condenser, evaporimeter.Generator comprises garden cylindricality box hat 1, ventilation steel pipe 2 is housed in it, equally distributed aperture is arranged on the pipe, box hat loam cake 4 is porose to join with head end condenser, six metal heat-conducting plate 3 equidistant being installed on the box hat inwall, anhydrous calcium chloride as absorbent covers between breather pipe and the box hat, and leaves expansion space.Condenser 5 is a seamless steel pipe, takes the shape of the letter U with a section of generator link, places air, and metal fin is housed on it, and another section spirally-wound places cooling water tank 6, and end and evaporimeter join.Evaporimeter 7 is the steel pipe thicker than condenser tube, places in the refrigerating box 8.Refrigerating plant more than one group can be installed in a multipotency refrigerator as required.Heating plant is made up of combustion chamber 9 and the boiling water tube that is positioned on the top, combustion chamber.Food steamer places boiling water tube top.The combustion chamber is an empty rectangular casing in, can place multiple normal domestic use cooking stove in the case: as coal stove, liquified-gas stove, electric furnace, biogas stove, burning firewood kitchen range etc.Generator places the boiling water tube.

Refrigeration system of the present utility model is that the characteristic of utilizing calcium chloride can absorb or discharge ammonia under condition of different temperatures realizes refrigeration.After calcium chloride in the generator is subjected to the heating of boiled water, the ammonia that absorbs is discharged, the steam state ammonia that is released out changes ammoniacal liquor into through condenser and is stored in the evaporimeter.After stopping to add heater, the ammoniacal liquor in the evaporimeter is absorbed by the calcium chloride in the generator again, and evaporimeter is because the ammoniacal liquor evaporation has been taken away heat and cooling refrigeration rapidly.

The utility model adopts generator rational in infrastructure, has strengthened hot conduction, thereby has accelerated the refrigeration reaction, has that refrigerating capacity is unrestricted, refrigerating efficiency is high, noiseless characteristics.

The utility model is warded off combuster, can use various thermals source, as coal stove, gas burner, oil oven, biogas stove, electric furnace and burning firewood etc., has the characteristics in multipotency source.

The utility model also has multi-functional characteristics: freeze, boil water, cooking.

The utility model is simple in structure, and condenser uses water as cooling agent, and the pipe interior operating pressure is no more than 10kg/cm ², easy to operate, safe and reliable.

Most preferred embodiment of the present utility model:

The box hat of generator is 90 millimeters of thick 2 millimeters, external diameter, high 300 millimeters cylinder, breather pipe is 20 millimeters of external diameters, thick 1 millimeter, long 300 millimeters steel pipe, six thick 2 millimeters, wide 34 millimeters, and long 300 millimeters equidistant being installed on the box hat inwall of metal heat-conducting plate.Small garden hole, anhydrous calcium chloride that it is 1 millimeter that the breather pipe sidewall has 120 diameters, be evenly distributed are put between breather pipe and the box hat, and stay 1/4th space, and its quantity is by 8 kilograms of calculating of 1000 kilocalories of preparations of phase refrigerating capacity weekly.Condenser adopts thick 1 millimeter, 18 millimeters of external diameters, be about 3 meters seamless steel pipe, curves about 1 meter an of segment length of U-shaped, about 2 meters of a helically wound segment length.Evaporimeter adopts 60 millimeters of thick 1.5 millimeters, external diameter, long 200 millimeters airtight steel cylinder.The multipotency refrigerator of Huo Deing in one day (24 hours), boils water once and keeps water and boiled 40 minutes like this, can obtain the per hour refrigerating capacity more than 30 kilocalories.
