Description

Technical field

[0001] The invention relates to a cooking pressure cooker, in particular to a pressure cooker with the functions of preventing splashing and collecting oil and water. Background technique

[0002] For the cooking pressure cookers (hereinafter referred to as pressure cookers) commonly used by the public on gas stoves or induction cookers, for safety reasons, a gravity pressure limiting steam valve (hereinafter referred to as pressure limiting valve) is set on the lid of the pressure cooker. When the pressure cooker is exhausting steam under pressure limiting, most of the gas is ejected from the four steam exhaust holes (hereinafter referred to as cap holes) on the gravity cap of the pressure limiting valve (hereinafter referred to as the valve cap), and the following inconveniences are likely to occur: 1. The hot air mixed with oily water and fine food particles (hereinafter collectively referred to as mixed fluid) sprayed in the horizontal direction is easy to spl...

Examples

Embodiment 1

[0025] The pressure cooker with the functions of preventing splashing and collecting oil and water in the first embodiment of the present invention (see figure 1 , figure 2 with Figure 7 ), including a pot body 10 with a pressure cooker and a matching pot cover 1 with a pressure limiting valve. The pot cover 1 has a cylinder surrounding the pressure limiting valve to block the mixed fluid sprayed from the pressure limiting valve. The structure of the cover 2 is characterized in that: the lower part of the cylinder cover 2 is provided with a receiving groove 3 on the pot cover 1 around the pressure limiting valve bonnet 11; the receiving groove 3 is formed by the cylinder wall of the cylinder cover 2 and the inner side The inner ring wall 31 of the through hole 311 and the groove bottom 32 integrally connected between the bottom ends of the two are formed; the minimum diameter of the through hole 311 is larger than the maximum outer diameter of the upper end of the bonnet 11, so...

Embodiment 2

[0033] The pressure cooker with functions of preventing splashing and collecting oil and water in the second embodiment of the present invention (see image 3 , Figure 4 with Figure 6 to Figure 8 ). On the basis of the first embodiment of the present invention, in order to make the function of the pressure cooker of the present invention more perfect and make it easier to implement and apply, the following structure is further constructed, namely:

[0034] Further structure 1: The inner ring wall 31 is provided with a shoulder 4 on the pot cover 1 surrounding the pressure limiting valve. The shoulder 4 is connected to the lower end of the pressure limiting valve seat 13 through the sleeve hole 41. There is a suitable distance between the shoulder 4 and the bottom side of the valve cap 11 for the passage of the mixed fluid; the barrel cover 2 and the receiving groove 3 are looped on the shoulder 4 through the inner ring wall 31; the shoulder 4 There is a suitable gap between it ...

Embodiment 3

[0044] The pressure cooker with functions of preventing splashing and collecting oil and water in the third embodiment of the present invention (see Figure 5 to Figure 8 ), compared with the second embodiment of the present invention, the structure is different in:

[0045] The above-mentioned sleeve 4 is an integral structure with the pot cover 1.

[0046] In the structure of the third embodiment, the independent component, namely the shoulder 4, is omitted, and the partial structural matching changes on the pot cover 1 can realize the structural function of the shoulder 4 in the second embodiment, so that the pressure cooker of the third embodiment The structure is more compact, more convenient to use and easy to promote and apply.

[0047] The other structures and corresponding functions in the third embodiment correspond to those described in the first and second embodiments, and will not be repeated here.

[0048] Obviously different from the prior art, the special receiving gr...
