The technical solution of the utility model embodiment is explained below with reference to the attached drawing of the utility model embodiment and
Illustrate, but following embodiments are only the preferred embodiment of the utility model, and not all.Based on the implementation example in the implementation mode,
Those skilled in the art's obtained other embodiments without making creative work, belong to the utility model
Protection scope.
Embodiment one
The pressure cooking appliance of the present embodiment can refer to Fig. 2-Fig. 4, including pot body (not shown) and pot cover 300, pot
The roof of the pressure limiting valve 100 that lid 300 is equipped with exhaust pipe 200 and is coupled with exhaust pipe, the pressure limiting valve 100 is equipped with valve
Core 4, spool 4 seal the exhaust outlet of the exhaust pipe 200, and the extraneous exhaust passage of connection is additionally provided on the roof of pressure limiting valve 100,
At least partly angle of airflow direction and horizontal plane that is discharged after the exhaust passage of gas is less than 90 degree.The present embodiment passes through
Exhaust passage changes gas flow direction, makes it and is discharged non-perpendicular to horizontal plane, the airflow direction of discharge can be made separate
User reduces the risk of user's scald.But also air velocity can be slowed down, reduce noise.
Specifically, the air exit of the exhaust passage is side opening 5, gas is through 5 discharge of side opening.Therefore
The airflow direction that gas is discharged deviates vertical direction, so that airflow direction may be located remotely from user, and structure is simple, and effect is obvious.
In the present embodiment, the exhaust passage includes vertical section channel and traversing section channel, and the pressure limiting valve 100 is perpendicular
Stop surface 6 is equipped with above straight section channel, the stop surface 6 forms the side opening 5 and traversing section channel.It can refer in Fig. 3
Arrow direction, gas by vertical section channel when up going out, by the blocking of stop surface 6, therefore change airflow direction,
It is discharged from traversing section channel, due to being equipped with stop surface 6, changes airflow direction, and exhaust velocity can be slowed down, reduce use
The risk of family scald, improves the safety of exhaust.In the prior art, when spool 4 releases the sealing to exhaust pipe, high pressure gas
Cognition is sprayed from exhaust pipe, is exhausted directly to the external world by vertical exhaust passage, and air velocity is fast, and temperature is high, is easy
User is damaged, and there are biggish noises.And in the present embodiment, since stop surface 6 is arranged, high pressure gas is spraying
When, it impacts on stop surface 6, airflow direction can be changed, and air velocity can be slowed down, noise can also be reduced.
Optimal, the vertical section channel is completely covered in the stop surface 6.By backstop above the i.e. described vertical section channel
Face 6 stops, and when so that gas being gone out from vertical section, the airflow direction for the gas that can all change airflow direction, therefore go out is equal
Angle with horizontal plane is less than 90 degree, so that it is guaranteed that safety exhaust.
In the present embodiment, the pressure limiting valve 100 includes plastics valve body 3 and metal valve disc 7, and the spool 4 is fixed on gold
Belong on valve disc 7, the metal valve disc 7 is equipped with through-hole 8, and the through-hole 8 constitutes the vertical section channel.When installation, it can be
Spool 4 is fixed on metal valve disc 7, metal valve disc 7 is placed in mold cavity, the plastics of melting are molded in mold cavity
Plastics valve body 3 is formed, through-hole 8 is set on metal valve disc 7, can be convenient and metal valve disc 7 is fixed, and through-hole 8 can
It is vented to vertical direction after injection molding with facilitating.The plastics valve body 3 of the present embodiment forms the side opening 5.That is plastic valve
Body 3 covers through-hole 8, but stop surface 6 is arranged above plastics valve body 3, and stop surface 6 is higher than through-hole 8, so that a side is formed with
Side opening 5, when spool 4 releases the sealing to exhaust pipe 200, gas can be gone out from through-hole 8, then pass through stop surface 8
After backstop, gone out from side opening 5.Therefore it can control gas to be vented to the direction far from user, it is ensured that exhaust, safety.Due to
Side opening 5 is formed directly on plastics valve body, is simple to manufacture, not will increase manufacturing cost.
Embodiment two
The present embodiment be it is further on the basis of example 1 improved, in the present embodiment, on the pressure limiting valve
Equipped with the first position limiting structure, the pot cover is equipped with the second position limiting structure, when the pressure limiting valve is installed to pot cover, first limit
Bit architecture and the cooperation of the second position limiting structure.By the way that position limiting structure is arranged, when so that pressure limiting valve being installed to pot cover, position is fixed,
But also the air exit of pressure limiting valve can be in fixed direction.It is optimal, when the pressure limiting valve limit is fixed to the pot cover,
The airflow direction that gas is discharged after the exhaust passage is far from pot cover front.In the prior art, when pressure limiting valve is installed to pot cover,
After its sealing exhaust pipe, pressure limiting valve can be rotated arbitrarily, air exit straight up so that gas rushes from vertical direction
Out.The present embodiment is by setting position limiting structure, so that pressure limiting valve, after being installed to pot cover, pressure limiting valve is arbitrarily to rotate,
Therefore the discharge directions of pressure limiting valve be can control.Specifically, by the setting of position limiting structure, so that the side mouth on pressure limiting valve
Towards rear portion, therefore high pressure gas is when going out, and is gone out to pot cover rear, so as to far from user, it is ensured that safety exhaust,
Avoid scald user.
Specifically, can refer to Fig. 5 and Fig. 6, first position limiting structure is the protrusion 9 on pressure limiting valve, second limit
Structure is the groove 10 on pot cover, and when the pressure limiting valve is installed to pot cover, described raised 9 are located in the groove 10.Due to
Pressure limiting valve is equipped with protrusion 9 so that pressure limiting valve is only when fixed direction is installed to pot cover, could sealing exhaust pipe, and this
When allow side mouth towards pot cover rear portion just so that before the airflow direction that is discharged after the exhaust passage of gas is far from pot cover
Portion, so as to ensure using safe.Certainly, in other embodiments, being also possible to first position limiting structure is pressure limiting valve
On groove, second position limiting structure be pot cover on protrusion.
In order to facilitate user installation, the pressure limiting valve is equipped with the first sign, and the pot cover is equipped with corresponding the
Two signs.Pressure limiting valve is placed in pot cover when installing pressure limiting valve, by corresponding second sign of the first sign by user
On, so that position limiting structure just cooperates, so that sidewall opening is towards pot cover rear portion, to realize the correct installation of pressure limiting valve.
In other embodiments, the first position limiting structure may be the protrusion on pressure limiting valve side or top, corresponding pot cover
It is equipped with the groove of cooperation, realizes the limit to pressure limiting valve circumferential direction.
