CN2314691Y - Anti-block pressure limiting device for pressure cooker - Google Patents

Abstract

The utility model provides a pressure limiting device for a pressure cooker which can automatically clean stemming. The utility model belongs to the technical field of cooking appliance of a kitchen. The utility model is mainly composed of an exhaust pipe and a pressure limiting valve. The pressure limiting valve is a cone. The inner space of the exhaust pipe is a cone, and the top part of the cone is cut off. The pressure limiting valve is completely filled in the exhaust pipe, which can effectively push small food particles which go into the exhaust pipe out of the exhaust pipe.

Description

The anti-blocking pressure limiting device of pressure cooker

The utility model provides a kind of energy anti-blocking pressure cooker pressure limiting device, is fit to be used in the kitchen use on the pressure cooker of cooking food, belongs to cooking utensils field, kitchen.

The existing pressure cooker pressure limiting device that is used for cooking food because of structural reason, in use, particularly boiling when easily boiling food, often makes tiny food particle easily, enters in the blast pipe with the high speed ejection of steam.Plug is many more more in thinner blast pipe for fine particle, easily blast pipe is stopped up, and high steam can't be discharged smoothly, and increasing being easy to of pot inner pressure has an accident.Current pressure pot clogging-preventing measures is a lot, as Anti-stop cover, devices such as safety valve are installed.Though Anti-stop cover is difficult for stopping up, violent in boiling, fine particle more still can stop up it.Block at blast pipe, during with the safety valve exhaust, fine particle also can stop up safety valve.Danger still can not be eliminated when pressure cooker used.

The purpose of this utility model provides a kind of when cooking food, the pressure cooker pressure limiting device that can tamper be disposed by self strength.

The utility model is achieved in that it mainly is made up of pressure limiting valve 6 blast pipes 7, and blast pipe 7 inner spaces are conical, most advancedly clips a bit of inner cone, forms steam vent 12.Pressure limiting valve 6 is a cone, and directly matches with blast pipe 7, and blast pipe 7 is full of by pressure limiting valve 6, and the forward tip of pressure limiting valve 6 can reach the purpose of removing with in tamper top twice-cooked stir-frying again.Blast pipe is installed on the pressure cooker cover with nut 11.

Advantage of the present utility model is to utilize the effect removing tamper of self to avoid tiny food particle to result in blockage in blast pipe.

Below be to be elaborated with the enforcement side in conjunction with the accompanying drawings.

Fig. 1 is a structure chart of the present utility model.

Fig. 2 is vertical middle profile of the present utility model.

Fig. 3 is part element structure figure among Fig. 1.

Fig. 4 is that Figure 1A is to view.

With we daily pressure cooker 50kpa, two kinds of pressure of 80kpa require to describe for example in the present embodiment.The diameter of the steam vent 12 of blast pipe 7 matches with the weight of pressure limiting valve 6, makes pot inner pressure can reach the requirement of 50kpa.The bottom outer rim of blast pipe 7 has screw thread, can blast pipe 7 be installed on the pressure cooker cover 9 with nut 11, for preventing to leak gas between blast pipe and the pot cover, can fill up last layer rubber ring 8 in the middle of them, and nut 11 is tightened by the breach 10 at its edge.Handle 4 is arranged on the pressure limiting valve 6, and handle 4 upper ends are equipped with bakelite 3, can pressure limiting valve 6 be taken up and down 3 by bakelite.Blast pipe 7 should be able to reach the air-tightness requirement with cooperating of pressure limiting valve 6.When vapour pressure in the pressure cooker reached the 50kpa requirement, pressure limiting valve 6 was by jack-up, and steam is discharged by steam vent 12.If at this moment there is fine particle stifled in steam vent, when pressure limiting valve 6 falls, can be with in particle top twice-cooked stir-frying again, even particle enters in the blast pipe, pressure limiting valve can't with in its top twice-cooked stir-frying because the blast pipe interior shape be upper coarse and lower fine, particle also can be blown out outside the blast pipe by steam, unlikely resulting in blockage.When pressure requires to 80kpa, can as above secondary pressure limiting valve 1, two apertures 5 are arranged on the secondary pressure limiting valve 1, two small columns 2 are arranged on the pressure limiting valve 6, as long as aperture 5 and small column 2 correspondences are installed to together, secondary pressure limiting valve 1 just has been installed on the pressure limiting valve 6.

Claims (4)
