Description

A kind of anti-return steam device for cooking

Affiliated technical field

The utility model relates to a kind of steam device for cooking, particularly a kind of anti-return steam device for cooking.

Background technology

At present, occurring on the market with steam is the steam device for cooking of thermal medium cooking food, and replacing traditional is the device for cooking of thermal source with charcoal, coal or liquefied gas, can be steam device for cooking such as steam chafing dish, Steam stewing pot usually.The steam device for cooking is made up of the steam conveying pipe and the check-valves of steam raising plant, cooking-vessel, connection steam raising plant and steaming cooking device usually, and check-valves places the cooking-vessel below to be connected with an end of steam conveying pipe.Steam raising plant energising produces steam, and steam is by steam conveying pipe and check-valves, enters from check-valves to add hot water and food in the cooking-vessel; Check-valves is used to prevent that the interior soup juice of cooking-vessel, thing slag etc. from entering in steam conveying pipe or the steam raising plant, in order to avoid cause steam conveying pipe or situations such as steam raising plant inner accumulated residue is unhygienic, difficult cleaning.Check-valves also is called check valve in the prior art usually, generally includes electromagnetic type and mechanical type two big classes.Realize the valve plug that liquid or gas unidirectional flow (also have be called pellet shot from a slingshot) in the mechanical type check valve, ball-type, tapered, column type etc. are arranged usually.

The patent No. is that 91211637.4 denominations of invention are " quincunx electric-heating steam chafing dish ", is made up of pot body, steam lead, son pot and shower nozzle;

The patent No. is that 200520067539.5 denominations of invention are " steam device for cooking ", is made up of steam generator, steam pipeline, cooking-vessel and steam check-valves;

The patent No. is that 200610200241.6 denominations of invention are " steam chafing dish ", constitute by steam raising plant and steam-type chafing dish, steam raising plant is connected with the steam-type chafing dish by steam conveying pipe, and the steam-type chafing dish enters valve by the pot body with the steam that is connected bottom of pot body and constitutes;

The patent No. is that 200610048610.4 denominations of invention are " piston type steam fire pot ", by steam pipe be incorporated into the pot in form steam-heated chafing dish, in the pot of chafing dish, be provided with cylinder, in cylinder, be provided with piston, and on piston, offer the admission opening of vertical stratification; Piston base in the cylinder lower end connects with steam pipe; In cylinder, be provided with the fastening structure of control piston stroke.

They all have pollution-free, heating is fast, efficient is high, food can not produce and overdo or advantages such as superheating phenomenon, the original delicate flavour of maintenance food and characteristic; But shortcoming of they common existence: though they all have soup juice in the cooking-vessel of preventing, thing slag etc. enters the check-valves in steam conveying pipe and the steam raising plant, but when using the steam device for cooking, cooking-vessel also is equipped with soup juice if steam raising plant stops heating, the thing slag, owing to rapidly cool off can produce very big negative pressure in steam raising plant and the steam conveying pipe this moment, check-valves is difficult to overcome negative pressure and stops soup juice in the cooking-vessel, the thing slag enters in steam conveying pipe and the steam raising plant, thereby causes steam conveying pipe or steam raising plant inner accumulated residue unhygienic, situations such as difficult cleaning take place.

The utility model content

The purpose of this utility model is to provide a kind of anti-return steam device for cooking that can overcome above-mentioned prior art shortcoming, and it can prevent in soup juice, thing slag backflow steam conveying pipe or the steam raising plant effectively.

The purpose of this utility model is achieved through the following technical solutions: a kind of anti-return steam device for cooking, comprise steam conveying pipe and check-valves between steam raising plant, cooking-vessel, connection steam raising plant and the cooking-vessel, check-valves is positioned at cooking-vessel and is connected in an end of steam conveying pipe, it is characterized in that: be equipped with the covering air assembly on steam conveying pipe outside cooking-vessel or the steam raising plant.

The beneficial effects of the utility model: produce on the steam conveying pipe of negative pressure or the steam raising plant in meeting and to be equipped with the covering air assembly, the covering air assembly replenishes air in steam conveying pipe and steam raising plant when steam raising plant stops to heat, eliminate negative pressure, therefore part lifes such as check-valves, steam conveying pipe, steam raising plant are long, stability is high, and it is effective to prevent that soup juice, thing slag from refluxing.

Description of drawings

Below in conjunction with accompanying drawing the utility model most preferred embodiment is elaborated.

Fig. 1 is the structural representation of the utility model most preferred embodiment.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in detail.

According to anti-return steam device for cooking shown in Figure 1, comprise steam raising plant 10, cooking-vessel 40, connect steam conveying pipe 30 and check-valves 50 between steam raising plant 10 and the cooking-vessel 40, check-valves 50 is positioned at cooking-vessel 40 and is connected in an end of steam conveying pipe 30, is equipped with covering air assembly 20 on steam conveying pipe 30 outside cooking-vessel 40 or the steam raising plant 10; Covering air assembly 20 preferably places on the gas outlet 11 of steam raising plant 10.Covering air assembly 20 can also place on the steam conveying pipe 30 or the top of steam raising plant 10.

According to covering air assembly shown in Figure 1 20 is check-valves.Check-valves comprises housing 21, baffle plate 22 and valve block 23, and baffle plate 22 places in the housing 21, and air admission hole 221 and installing hole 222 are arranged on the baffle plate 22, and axle 231 is arranged on the valve block 23, and valve block 23 places in the installing hole 222 on the baffle plate 22 by axle 231; The most handy resistant to elevated temperatures silica gel material of valve block forms.

When using the steam device for cooking, steam raising plant 10 energisings produce steam (not drawing among Fig. 1), and steam comes out from the gas outlet 11 of steam raising plant 10, by steam conveying pipe 30 and check-valves 50, enter and add hot water and food in the cooking-vessel 40; Check-valves 50 is used to prevent that the soup juice, thing slag in the cooking-vessel 40 etc. from entering in steam conveying pipe 30 or the steam raising plant 50, in order to avoid cause steam conveying pipe 30 or situations such as steam raising plant 10 inner accumulated residues are unhygienic, difficult cleaning.When steam raising plant 10 stops to heat, produce very big negative pressure owing to cool off meeting rapidly in steam raising plant 10 and the steam conveying pipe 30, this moment, air outside will be by the air admission hole 221 on covering air assembly 20 Internal baffles 22, push valve block 23 open, valve block 23 is opened along axle 231 directions, air outside is replenished in steam conveying pipe 30 and steam raising plant 10, eliminate negative pressure, can not produce suction, prevent that effectively soup juice, thing slag are back in steam conveying pipe 30 or the steam raising plant 10 the soup juice in the cooking-vessel 40, thing slag etc.
