Description

Square pipe and snap fastener button cooking and heating furnace

The utility model relates to a kind of square pipe and snap fastener button cooking and heating furnace, and the national uses cooking and heating furnace tool technical field.

At present, the most cooking effect of coal domestic cooking heating stove is undesirable, and one of its reason is that the radiation heat loss is many because the distance between the fire coal and the bottom of a pan is big.As a kind of cooking heating dual-purpose stove that Chinese patent CN90224495.7 introduces, its structure as shown in Figure 1.It by stone or metal plate for standing a stove on as a precaution against fire 1, movable adjusting ring 2, secured adjusted circle 3, lead fire lid 4, inner water sleeve 5, outer water jacket 6, circle tube connector 7, insulating layer of furnace body 9, inner thermal insulating layer 10 and tile 11 etc. and form.Enter inner water sleeve through the circle tube connector after the water at low temperature of returning from the radiator water jacket heating outside and heat up once more, and then spray into heating system through another circle tube connector.Make coal-fired distance with the bottom of a pan near, just require inner water sleeve short, it is thin that tube connector certainly will be wanted.But after tube connector attenuated, it is big that resistance to water-flow becomes, and discharge diminishes, and this just makes the heating effect variation, and water easily gasifies in the inner water sleeve of high temperature, produces the pneumatic hammer sound that makes one nervous.The operation of banking up a fire of this stove simultaneously realizes by regulating secured adjusted circle and movable adjusting ring, the two all has the air vent that quantity equates, shape is identical, when rotation activity adjusting ring, the hole size that staggers mutually changes, in the time of completely wrong, the hole contract fully, be the state of banking up a fire, hole is entirely on time, for complete opening wide burnt, during partial transposition, by the size adjustment ventilation of dislocation.But during actual the use, this adjusting can not realize banking up a fire fully.Because very big at following two place's inleakages, the one, secured adjusted circle and water jacket end are fitted bad, produce gas leakage in a large number; The 2nd, the secured adjusted circle is fitted badly with leading fire lid, also produces and leaks out in a large number.

The purpose of this utility model is a kind of square pipe and snap fastener button cooking and heating furnace of design, improves secured adjusted circle wherein and leads the structure of fire lid, makes its good seal performance, realizes banking up a fire full function.Improve water jacket tube connector shape, make its hot water circuit fast, heating effect is good, eliminates gas hammer phenomenon, and coal-fired distance with the bottom of a pan is dwindled, and the cooking firepower is stronger.

The square pipe and snap fastener button cooking and heating furnace of the utility model design comprises stone or metal plate for standing a stove on as a precaution against fire, movable adjusting ring, secured adjusted circle, leads fiery lid, inner water sleeve, outer water jacket, water jacket tube connector, insulating layer of furnace body, inner thermal insulating layer and tile.The cross section of water jacket tube connector wherein is that higher primary school is in wide rectangle.The lower surface of leading the fire lid is a taper seat, and the outer of leading the fire lid is to lower process.The internal orifice edge of secured adjusted circle is to upper process, and this projection forms double buckle with the downward projection in outer of leading the fire lid.The outer of secured adjusted circle is to lower process, and this projection forms double buckle with the projection of outer water jacket inwall end.

Owing to the utlity model has above design feature, not only make the hot water circuit of heating fast, improved the thermal efficiency, eliminate gas hammer phenomenon, and strengthened the cooking firepower, solved the common fault of heating stove cooking weak effect.The effect of banking up a fire of stove and accessory is greatly improved.

Below in conjunction with accompanying drawing, introduce content of the present utility model in detail.Among Fig. 1 to Fig. 5, the 1st, stone or metal plate for standing a stove on as a precaution against fire, the 2nd, movable adjusting ring, the 3rd, the secured adjusted circle, the 4th, lead the fire lid, the 5th, inner water sleeve, the 6th, outer water jacket, the 7th, the tube connector of inside and outside water jacket, the 8th, outer water jacket inwall end, the 9th, insulating layer of furnace body, the 10th, inner thermal insulating layer, the 11st, tile, the 12nd, outlet pipe, the 13rd, twice aeration chamber, the 14th, water inlet pipe, the 15th, coal-fired, the 16th, cone of radiation is led the fire lid.

The formation of the utility model water jacket is that the cross section of the tube connector 7 between outer water jacket 6 and the inner water sleeve 5 is that a higher primary school is in wide rectangle, i.e. deltiod.Inner water sleeve just can be done very shortly like this, has shortened the distance coal-fired and the bottom of a pan, thereby has strengthened the cooking firepower.After the inner water sleeve change was short, its water capacity greatly diminished, and it is in the high-temperature region again in addition, and water is easy to boiled gasification, so require the sectional area of tube connector to want big, to quicken water circulation, eliminated gas hammer phenomenon.In design,, just can obtain this effect as long as strengthen the width of square tube.

The structure of envelope wind apparatus of the present utility model is, 8 places, inwall end of outer water jacket 6 are to upper process, exceed the some millimeters of upper head plate of water jacket, and the downward some millimeters projection stile of a circle is made in the outer of secured adjusted circle 3, the internal diameter of stile is slightly larger than the external diameter of outer water jacket inwall tip protrusion, upwards, two downward projections just fasten formation " double buckle ".Also the form of double buckle can be designed to as shown in Figure 6.Among Fig. 6, the inwall of outer water jacket 6 does not exceed end plate, and the structure of secured adjusted circle as shown in Figure 7, the downward some millimeters stile projection of its outer is moved inwards, and make the internal diameter of the outer warp of stile less than outer water jacket 6 inwalls, and can just insert into, form " double buckle ".The internal orifice edge of secured adjusted circle 3 is made a circle and is upwards exceeded some millimeters projection stile, the cone of radiation that interlocks is with it led the outer of fire lid 16 and is also made the downward some millimeters stile projection of a circle, its internal diameter is greater than the external diameter of secured adjusted circle internal orifice edge projection, this makes progress, two downward projections also just fasten, and forms " double buckle ".The problem of leaking out in such two places has just all solved, thereby the performance that stove and accessory is banked up a fire is improved greatly.

Form " double buckle " owing to lead the Huo Gai outer, it is tighter to bank up a fire, and therefore leads fire lid 16 and can make lower surface and become the conical surface downwards, so that the inner water sleeve of the heat that comes on the radiation of burner hearth around being radiated with diffusion mode, improves the utilization rate of heat.
