The specific embodiment
Describe the preferred embodiments of the present invention with reference to the accompanying drawings in detail.
Fig. 1 to 6 is views of the safe locking device of first embodiment of the invention heat preservation pressure electric cooker.Fig. 1 is the sectional view of heat preservation pressure electric cooker, and Fig. 2 and 3 is planes of pot cover locking and open mode, and Figure 4 and 5 are sectional views of pot cover locking and open mode.
Referring to figs. 1 through 5, body cover 2 is connected through the hinge on the top of the main body 1 of heat preservation pressure electric cooker, and opens it/close with rotary way, and pot body 3 is placed in the main body 1, and pot cover 4 is connected the top of pot body 3.
Rotating ring 5 is connected the top of pot cover 4, and connecting rod 7 is connected between the turning handle 6 and pot cover 4 that links to each other with body cover 2.When making turning handle 6 rotations, transmit revolving force by connecting rod 7 and make rotating ring 5 rotations.
End at connecting rod 7 is provided with connecting hole 7a, and makes on its Connection Element that is connected to turning handle 6 lower ends.Be provided with long connecting hole 7b in the other end both sides of connecting rod 7, these long connecting hole 7b are connected respectively to the connecting pin 5b on the rotating ring 5.
A plurality of holders 8 (shown in the figure 4) are connected between pot cover 4 and the rotating ring 5, so that shifted to the medial/lateral of radial direction by the central shaft of main body 1 along straight line.The guide finger 8a that is fixed on holder 8 upper surfaces inserts in the inclined hole 5a on the rotating ring 5.When rotating rotating ring 5, a plurality of holder 8 is shifted to medial/lateral along straight line.In an inclined hole 5a of rotating ring 5, be provided with hook portion 5c.
The hook portion 8b of " ㄈ " shape is arranged on the holder 8, and is hooked on the hook portion 3a and 4a that is given prominence to by pot body 3 and pot cover 4 excircles.
In the safe locking device of first embodiment of the invention heat preservation pressure electric cooker, when making that turning handle 6 rotates, rotate rotating ring 5 by connecting rod 7, when rotating ring 5 turns clockwise, as shown in Figure 2, the inclined hole 5a of rotating ring 5 inwardly promotes guide finger 8a, and holder 8 is to the medial movement of radial direction.Therefore, as shown in Figure 4, the hook portion 8b of holder 8 is hooked on the hook portion 3a and 4a of pot body 3 and pot cover 4 with distance ' b ', thereby pins pot cover 4 safely.
As shown in Figure 3, when rotating counterclockwise rotating ring 5, the inclined hole 5a of rotating ring 5 outwards promotes guide finger 8a, and holder 8 is to the outer side shifting of radial direction.Therefore, as shown in Figure 5, the hook portion 3a and the 4a gap separation ' c ' of the hook portion 8b of holder 8 and pot body 3 and pot cover 4, thus allow the user freely to open pot cover 4.
When steamed rice, the user is by the holder 8 locking pot covers of safe locking device, and when having steamed meal, the user opens pot cover 4 by the locking state that discharges holder 8.
Or rather, be rotated the inclined hole 5a of ring 5 by turning handle 6, connecting rod 7 and rotating ring 5 the Unscrew/power of closing on the holder 8 of acting on and the guide finger 8a of holder 8 converts straight line component to.Therefore, when rotation turning handle 6, holder 8 can move to the medial/lateral of radial direction.
Security in the safe locking device of heat preservation pressure electric cooker is very important.When pot body 3 internal pressures were very high in the steamed rice process, if discharge the locking state of pot cover 4, high pressure can be opened pot cover 4 and a pot interior thing is shed, and may hurt the user.Therefore, be necessary that device safe in utilization prevents to be opened when pot cover 4 from forming high pressure in pot body 3.The hook portion 5c that forms on inclined hole 5a plays the effect that reduces straight line component, and this straight line component is by acting on the turning handle 6 so that Unscrew/the power of closing that moves holder 8 along radial direction converts.That is to say that hook portion 5c role is the guide finger 8a that prevents from outwards to promote holder 8, keep the locking state of pot cover 4 thus.
Fig. 6 A is when producing predetermined pressure in pot body 3, the hook portion 5b of inclined hole 5a is hooked in the plane of the guide finger 8a of holder 8.Shown in Fig. 6 a, when producing predetermined pressure in the pot body 3, if rotate counterclockwise rotating ring 5 to open pot cover 4, the inclined hole 5a on the rotating ring 5 is rotated counterclockwise.When the guide finger 8a of the holder 8 hook portion 5c that ' a ' moves to ' a2 ' and be hooked in inclined hole 5a through ' a1 ' from the position went up, the straight line component that outwards promotes guide finger 8a reduced.Therefore outwards do not promote guide finger 8a, holder 8 maintains the lock status like this.
Fig. 6 B is the plane that the hook portion 5c of inclined hole 5a when not producing predetermined pressure in pot body 3 does not hook the guide finger 8a of holder 8.With reference to Fig. 6 b, when the predetermined pressure in the pot body 3 discharged, the guide finger 8a of holder 8 shifted to position ' a3 ' through the hook portion 5c of inclined hole 5a.As a result, rotate rotating ring 5 and discharge the locking state of holder 8 reposefully.
In the steamed rice process, when producing high pressure in the pot body 3, high pressure rises pot body 3, and the hook portion 3a and the 4a of pot body 3 and pot cover 4 are fixed on the hook portion 8b of holder 8 tightly, have limited the rotation of rotating ring 5.In addition, the hook portion 5c of inclined hole 5a has reduced to promote the component of the guide finger 8a of holder 8, has limited moving of holder 8 effectively.Therefore, holder 8 can not move laterally, thereby prevents that pot cover 4 from opening.
Fig. 7 to Fig. 9 is the view of the safe locking device of second embodiment of the invention heat preservation pressure electric cooker.Fig. 7 is the plane of pot cover locking state, and Fig. 8 is the plane of pot cover locking and open mode.
Shown in Fig. 7 and 8, in the safe locking device of the heat preservation pressure electric cooker of second embodiment of the invention, in the long connecting hole 7b of connecting rod 7 outer ends, be provided with the hook-type jaw 7c of portion.When producing predetermined pressure in the pot body 3, the connecting pin 5b of the connecting rod 7 of rotating ring 5 rotations is inserted in the hook-type jaw 7c of portion.Therefore, connecting rod 7 can not rotate rotating ring 5, thereby prevents that rotating ring 5 from rotating.
Fig. 9 A is that the guide finger of rotating ring 5 is hooked in the plane on the hook-type jaw 7c of portion of connecting rod 7 long connecting hole 7b.Shown in Fig. 9 a, when producing predetermined pressure in the pot body 3, the rotation of rotating ring 5 is restricted.Here, when being rotationally connected bar 7 by operation turning handle 6, the connecting pin 5b of rotating ring 5 is hooked on the hook-type jaw 7c of portion of connecting rod 7 long connecting hole 7b, and the hook-type jaw 7c of portion reverses an angle with connecting rod 7, so the revolving force direction of connecting rod 7 departs from the track of rotating ring 5.Even the user attempts to discharge halted state by rotation turning handle 6, can not rotate rotating ring 5.Therefore, locking state that can releasable clamps 8, thus pot cover 4 is opened.
Fig. 9 B is that guide finger is not hooked in plane on the hook-type jaw 7c of portion of connecting rod 7 long connecting hole 7b on the rotating ring 5.With reference to Fig. 9 b, when letting out except that predetermined pressure in pot body 3, rotating ring 5 can freely rotate.When being rotationally connected bar 7 by operation turning handle 6, the connecting pin 5b of rotating ring 5 is through the hook-type jaw 7c of portion of the long connecting hole 7b of connecting rod 7.Therefore, the rotatory force of connecting rod 7 is rotated rotating ring 5.In addition, therefore the locking state of the rotation releasable clamps 8 by rotating ring 5 opens pot cover 4.
Industrial applicibility
When the user used pot steamed rice, if having high pressure in the pot, pot cover just may be opened and make Thing overflows in high temperature and high pressure steam and the pot, and in this case, the user may be burned. As above Described, according to the present invention, when having pressure in the pot, even handle is rotated in rotation, still can keep The locking state of pot cover, thus Accident prevention takes place in advance.
