Description

Sterilising apparatus using waste heat of domestic pressure cooker

This utility model belongs to the decontaminating apparatus of domestic pressure cooker.

Existing domestic pressure cooker, when the pressure of pot surpassed the force value of this pot high pressure valve, unnecessary steam entered in the atmosphere by high pressure valve, failed to obtain fully effectively to utilize and had wasted.The used steaming lattice of ordinary pan are connected as a single entity by hollow Cylinder with its bottom, and the end that passage is arranged, cover lid at hollow garden styletable mouth, be contained in symmetric handgrip composition on the hollow Cylinder side, but these steaming lattice can not be collected the steam that pressure cooker emits, and realize utilizing the discharge steam of pressure cooker to carry out disinfection.

The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of UTILIZATION OF VESIDUAL HEAT IN decontaminating apparatus of domestic pressure cooker is provided.This device and the direct supporting use of domestic pressure cooker can utilize steam that pressure cooker emits to the sterilization that carries out disinfection of tableware, kitchen utensils and other household goods, make its hygiene, and this apparatus structure is simple, energy-conservation, safety, germicidal efficiency height.

For the purpose that realizes that foregoing invention is created; technical solution of the present utility model is to be equipped with to be the decontaminating apparatus housing of stairstepping through hole in one on the pot cover surface of domestic pressure cooker; steam grid plate is equipped with at ladder place at the stairstepping through hole; this housing upper end open is stamped pot cover; have passage on it; above high-pressure pot cover surface and high pressure valve; on the inner walls of the decontaminating apparatus of the below of steam grid plate; be fixed with the security grid computing cover; with the design protection mask with holes that upper base arranged and raise up on the pairing security grid computing cover of pressure cooker valve; high pressure valve stretches in this mask; be processed with passage on the whole security grid computing cover; hole on the security grid computing cover is circular hole or square hole or irregularly-shaped hole; the distance of protection mask upper bottom surface with holes and high pressure valve upper surface is 5-10mm; the inner cavity size of protection mask with holes is 2:1 with the ratio of high pressure valve maximum gauge, and protection mask with holes is 1.5:1 with the ratio of valve height.

This utility model is compared with background technology, have the following advantages: the high temperature residual air that this device can utilize the domestic pressure cooker to give off directly carries out disinfection to tableware, kitchen utensils, make aseptic process, both reached heat recovery, reach energy-conservation again, this device in use, to pressure cooker repeated experiments repeatedly, the pressure of this pressure cooker is in 1 kilogram/cm all the time ²Safe normal value does not have counter-pressure on the valve, can guarantee effective collection of normal emission gases of pressure cooker and gas, uses for sterilization, sterilization, and Disinfection Effect is good.Experimental result shows: the steam temperature of the normal discharging of pressure cooker is generally at 100 ℃-120 ℃, and the time of discharged steam is about 10-15 divides.Under said temperature, antibacterial, coliform, mycete, yeast etc. are as long as 3-5 minute scope is internal energy all to be killed, just adopt formula to survey bacterium device such as TT0000025, TC0000025 and TY0000025 the testing result of the antibacterial in the sample, coliform, yeast, mycete have been confirmed this point.This utility model is simple in structure, and is reasonable in design, and application popularization is strong.
