Abstract

The invention relates to high-temperature steam pressure cooking kitchenware, in particular to a hotcooker type cooker supplied with heat by steam. A cooker cover of the cooker is formed by superposing and knitting fibers of plant stalks or stems; the lower edge of the cooker cover has a circular section and the diameter of Phi50 to Phi30cm, and when placed on a cooker body, is in sealed contact with the inner wall surface of the cooker body; the upper end of a steam supply pipe of a steam distribution device is provided with external threads which are connected with internal threads at the top of a steam distribution cap inversely covered on the steam supply pipe; and steam distribution holes higher than the upper edge of the cooker body are radially uniformly distributed at the upper end of the steam supply pipe. The cooker of the invention ensures short cooking time, saves energy sources, avoids residual soup left in the steam supply pipe after a dinner, is sanitary and safe to use and widely applied to foods and makes more delicious the soup of the foods; and different plant fibers may have different kinds of plant aroma and function as medicated diets to a certain extent.

Description

A kind of no residual soup is from the pressure release steam pressure cooker

Technical field

The present invention relates to a kind of steam cooking cooker, the chafing dish type pot of heat particularly is provided with steam.

Background technology

What's frequently heard can be repeated in detail for people since ancient times to adopt steam to come cooking food, owing to the taste of food deliciousness of culinary art, do not get angry, nutritious, so liked by people.

Chinese patent literature 91218391.8,200420104602.3,90207621.3 discloses the technical scheme of some steam chafing dish, has solved the problem that traditional chafing dish is burned, and makes the taste of food deliciousness, and suitable use at the restaurant.But these steam chafing dish have the following disadvantages:

If do not add a cover when 1. cooking, under normal pressure, use Steam Heating, no vapour pressure in the pot, temperature is not high enough, and steam utilization is low, and cooking time is longer, wastes energy;

If 2. add a cover, steam can carry soup juice from outwards going out all around, is easy to scald desk people on every side and also pollutes the environment of having a dinner;

3. people at the restaurant the meal time short, can not at short notice a lot of foods (as steak, band kindred, belt leather meat etc.) be boiled crisp mashedly, so client is restricted the selection of food;

4. because the interior no pressure and temperature of pot is low, the soup delicate flavour of food is not enough;

5. soup juice can enter in the steam supply pipe from the cloth steam vent of low level, pollutes steam supply pipe, and the residual soup of breed bacteria can seal in client's pot of having a dinner next time again, and the harm people's is healthy.

Summary of the invention

Technical problem to be solved by this invention provides a kind of no residual soup from the pressure release steam pressure cooker, and cooking time is short, energy savings, and no residual soup in the steam supply pipe uses health, safety, and suitable food is wide, and the soup taste of food is more delicious.

The technical solution adopted in the present invention is:

1. to be that the fiber of plant straw or bar is overlapping knit pot cover, and pot cover lower edge cross section is circular, and its diameter is Φ 50cm～Φ 30cm, and the pot cover lower limb contacts with the internal wall pot body face is airtight,

2. the steam supply pipe of cloth vapour device upper end band external screw thread, the steam supply pipe diameter is Φ 8mm～Φ 20mm, is connected with the cloth vapour crown portion internal thread of left-hand thread on it, the cloth steam vent of radial equipartition is higher than a pot body top edge on the steam supply pipe.

The woollen yarn knitting thickness of described pot cover is 0.5cm～3cm, cloth steam vent on the steam supply pipe is provided with more than 6, the aperture is 0.5mm～2mm, cloth vapour cap lower edge is apart from the bottom of a pan 5～20mm, distance between cloth vapour cap inwall and the steam supply pipe outer wall is 1～10mm, and the through-hole diameter at bottom of pot body center is greater than steam supply pipe diameter 0.5mm.

The invention has the beneficial effects as follows:

1. pot cover adopts string, has constant weight, filament expansion behind the absorption steam, make pot cover have better seal, thereby after steam leads in the pot, can make the steam pressure that produces in the pot greater than the big steam pressure in the external world very soon, and kettle temperature is elevated to more than 100 degrees centigrade, remain steam pressure that traditional chafing dish do not have and the temperature of Geng Gao in the pot, and steam is emerged to the bottom of a pan periphery from cloth vapour cap lower edge by the cloth steam vent by steam supply pipe, forming steam easily rolls in food and soup, the steam utilization height, make heating more all even rapider, but therefore the fast cooking difficulty is stewed crisp food, and the time of cooking food is shortened greatly, both saved the energy, make the amino acid delicate flavour of food can be faster again, dissolve in the soup more, so the soup flavor is more delicious, different strings can give out different plant flavours and play certain herbal cuisine function simultaneously;

2. has suitable seal between the string of pot cover, steam pressure increases to one regularly in pot, steam can be with the size of pressure, slowly emerge in the string slit of squeezing the lid that boils in various degree, avoided steam to concentrate and gone out the phenomenon of scalding the people from the pot cover edge, make the present invention both have the function of pressure cooker, the danger of having avoided the pressure cooker improper use to blast again is fit to chafing dish restaurant and uses very much;

3. the distance in the cloth vapour cap lower edge and the bottom of a pan is 5～20mm, and uniform cloth steam vent position, steam supply pipe upper end is higher than a pot body upper edge, far above the surface of soup juice, does not therefore have residual soup and stockpiles in steam supply pipe, makes the use not only safety but also the health of steam copper of the present invention.

Fig. 1 is a structural representation of the present invention.

Among the figure: pot cover 1, handle 2, nut 3, cloth vapour cap 4, nut 5, steam supply pipe 6, sealing gasket 7, pot body 8, cloth steam vent 9.

The specific embodiment

Referring to Fig. 1,1. pot body 8 of the present invention adopts stone material, pottery or metal are processed into, 2. the fiber of pot cover 1 employing plant straw or bar is overlapping knits, the woollen yarn knitting thickness of pot cover 1 is 0.5cm～3cm, pot cover 1 lower edge cross section is circular, its diameter is Φ 50cm～Φ 30cm, pot cover 1 lower limb and airtight contact of pot body 8 internal faces, 3. cloth vapour device still adopts traditional pipeline steam supply, the upper end band external screw thread of steam supply pipe 6, cloth vapour cap 4 is the cover of left-hand thread on steam supply pipe 6, and it is fastened on the steam supply pipe 6 by the internal thread at top and the external screw thread of steam supply pipe 6 upper ends, and its lower edge is far from the bottom of a pan 5～20mm, distance between cloth vapour cap 4 inwalls and steam supply pipe 6 outer walls is 1～10mm, 4. the middle and lower part of steam supply pipe 6 has external screw thread, and steam supply pipe passes the through hole at center, the bottom of a pan, by nut 3, nut 5 and sealing gasket 7 are pressed abd fixed on center, the bottom of a pan with pot body 8, the position of the cloth steam vent 9 that steam supply pipe 6 upper ends are uniform is higher than the top edge of pot body 8, and cloth steam vent 9 is provided with more than 6, and the aperture is 0.5mm～2mm.
