Description

Pressure cooker

The utility model relates to a kind of pressure cooker.

For making pressure cooker when cooking, can bear high pressure; making unlikely between its pot cover and pot body is that good airtight security is pushed and kept to a gas high pressure open in the pot; usually can install a lock control devices that pot body and pot cover can be locked in the pressure cooker; at present existing pressure cooker lock control devices design; the pressure cooker that is disclosed for No. 92/03090 as disclosed PCTWO; as shown in Figure 6; on its pot cover 40 two relative pots of body 43 longitudinal axis of installing be radially relatively and can do to move radially buckle pawl 41; pot cover 40 central authorities install one in addition can make axially movable button 42; has a service portion 421 in the button 42; service portion 421 can be in the process of button 42 axial displacements relativity in the inclined plane part 411 of button pawl 41, make button pawl 41 produce radial displacements and a pot cover 40 and a pot body 43 are locked or unlock.

Because the type of drive that the utilization of aforementioned pressure pot lock control devices is axially changeed is radially controlled pot cover and pot body locking/unlocking state, have in the structure that member is on the high side, shortcoming such as complex structure and cost are higher, and need to see through a series of interactional component movement combinations, can guarantee to detain the locking of pawl and the control of release, thereby cause easily between member that frictional dissipation is big between the danger, member of clip mutually, more control locking/unlocking by the vertical action button in pot cover top, and have problems such as the application of force is difficult for, operation inconvenience because of need.

Therefore, because the shortcoming of aforementioned pressure pot lock control devices, a kind of pressure cooker structure shown in No. the 5613424th, United States Patent (USP) is arranged, please cooperate referring to Fig. 7, Fig. 8 and Fig. 9, the lock control devices 50 of this pressure cooker be contained on the pot cover 60 two relative pots of body 61 longitudinal axis of installing be radially relatively and can do to move radially buckle pawl 51, in addition in pot cover 60 central authorities installing one between the two wedge shape control pieces 52 of buckleing 51 of pawls, and utilize control piece 52 in the process that pot cover 60 central authorities laterally move, see through the effect of inclined-plane, wedge shape control piece 52 both sides 521 make-up pawls 51, make button pawl 51 produce radial displacements, a pot cover 60 and a pot body 61 are locked or unlock.

Though aforementioned pressure pot lock control devices is used radially mode of operation instead to improve the vertical unhandy problem of aforementioned pressure pot, still have many shortcomings such as operation effort, member be on the high side in its structure, so that cost is higher and reduce its competitiveness of product; On the other hand, aforementioned pressure pot lock control devices and early stage pressure cooker be with adopting the radially relative lock of the two button pawls structure of pulling, and be relatively poor to the lock that is provided between pot cover and the pot body power of pulling, and the safety in utilization of the best can't be provided.

Therefore, the purpose of this utility model is to provide a kind of rapid operation, easy, and can simplify structure, reduces cost and promote the pressure cooker of safety in utilization.

For reaching above-mentioned purpose, the technical solution of the utility model is to provide a kind of pressure cooker, comprises the pot cover that one pot of body, has lock control devices, and this pot cover is airtight to be covered on pot body, also comprise the control pot cover with button pawl and the lock control devices of locking/unlocking of pot body, it is characterized in that:

This lock control devices comprises at least two and is installed on the lid and the actuating arm that can do to move radially, the pull button pawl of pot body of this button is fixedly arranged on each actuating arm outboard end, lid central authorities are provided with one and revolve handle, but this revolves the bottom is driven the control that revolves that actuating arm moves radially in conjunction with a turn.
