Description

Split pressure cooking utensil

Technical Field

The invention relates to the technical field of kitchen appliances, in particular to a split pressure cooking appliance.

Background

At present, products such as electric pressure cookers on the market are all provided with pot cover structures, and the pot cover and a lower pot body are connected in two modes, namely split connection and conjoined connection. For the electric pressure cooker, the pressure control mode of the electric pressure cooker is determined by the connection mode, the pressure switch is generally used for controlling the pressure of the split connection product, the pressure switch is arranged at the bottom of the cooker body, and forms a pressure bearing structure with the disc spring, the heating disc and the inner container, when the pressure exists in the cooker, the inner container is pressed to slightly deform downwards, the heating disc is pushed to move downwards, so that the disc spring generates elastic deformation, the disc spring is contacted with the ejector rod of the pressure switch, when certain pressure is reached, the ejector rod pops the pressure switch, the pressure switch is connected with the heating disc in series, the heating is disconnected, and the purpose of controlling the pressure is achieved. The other is a connection mode, the temperature measurement at the top is generally used for controlling the internal temperature, the temperature and the pressure have a certain corresponding relation, so that the purpose of controlling the pressure is achieved, a pressure switch can also be used for controlling the pressure, and the pressure control structure is the same as that of a split body.

When using electric pressure cooker culinary art food, in order to reach the best culinary art effect, different food need use different pressure culinary arts, and it is more even to use IH electromagnetic heating technique than the heating of ordinary dish that generates heat moreover, and the effect is better, experiences better. In the prior art, the split connection type electric pressure cooker product has the advantages of simple pressure control structure and low cost, is convenient for a user to detach and clean, can only control one pressure, and cannot realize control of a plurality of pressures. And because IH electromagnetic heating structure restriction does not have the pressure-bearing structure, so also can not make IH electromagnetic heating, so use the product food culinary art effect of this accuse pressure mode relatively poor. And another kind of disjunctor connected mode can use top accuse temperature mode to realize a plurality of pressure control, and can realize IH electromagnetic heating, but the structure is more complicated, and the cost is higher, so general product selling price is higher, and the user also can not bear higher price, and the user can not pull down the upper cover washing, breeds the bacterium easily, experiences relatively poorly.

In order to combine together the advantage of two kinds of connected modes, consequently carry out coupled connection through coupler and a kind of deep pot body at the structural upper cover department of components of a whole that can function independently increase a top temperature measuring device, realize accurate accuse temperature accuse pressure, the user can pull down the pot cover and wash, and the structure is simpler, and the cost is lower, promotes product experience.

After the coupler is arranged on the cooker cover, the split pressure cooker can be electrically connected, but the problems that when the cooker cover is combined with or buckled with the cooker body cover, the upper coupling part and the lower coupling part are reliably electrically connected, and the service life is short are solved. In particular, the connectors of the prior art are circumferentially inserted and coupled, and the locking action causes the two couplers to frequently collide with each other, and the couplers are short in service life due to abrasion and deformation.

Detailed Description

The present invention will be described in further detail with reference to the following detailed description and accompanying drawings. It should be emphasized that the following description is merely exemplary in nature and is not intended to limit the scope of the invention or its application.

Non-limiting and non-exclusive embodiments will be described with reference to the following figures, wherein like reference numerals refer to like parts, unless otherwise specified.

A split pressure cooking appliance as shown in fig. 1, the cooking appliance shown in the figure is an electric pressure cooker, the cooking appliance includes a lid 200, an inner container 400 and a pot body 100, the lid 200 covers the pot body 100 in a completely detachable manner, so-called completely detachable, that is, the lid 200 can be completely removed from the pot body 100, and the lid 200 is washed when needed, or placed on a table or a cooking bench, so as to prevent the lid 200 from being hinged or plugged on the pot body 100, which affects the cooking operation of the user on food in the inner container 400.

The cooker cover is provided with an outer cover 201 and a locking cover 202 provided with a locking structure 203, for the electric pressure cooker, the cooker cover 200 is not simply covered with the cooker body 100, in order to effectively press up, the cooker cover 200 is provided with the locking structure 203, the locking structure 203 is arranged on the locking cover 202, the locking cover 202 is fixed on the outer cover 201, the cooker body is provided with a locking structure 101, correspondingly, the locking structure 203 is generally cover teeth, the locking structure 101 is cooker teeth, when the cooker teeth are meshed with the cover teeth, the cooker teeth are in a locking position, locking is realized between the cooker cover 200 and the cooker body 100, and when the cooker teeth are staggered with the cover teeth, the cooker body 100 and the cooker cover 200 are in an unlocking position, and unlocking is realized between the.

In order to realize the top temperature measurement of the split pressure cooking appliance and improve the cooking effect, a coupler 300 is arranged between the cooker body 100 and the cooker cover 200 to realize the electric connection, the coupler 300 comprises an upper coupling part 302 and a lower coupling part 301, the upper coupling part 302 is arranged on the cooker cover 200, the lower coupling part 301 is arranged on the cooker body 100, and after the locking is completed, the upper coupling part and the lower coupling part realize the coupling, so that the top temperature measurement can be realized only after the cooker cover 200 is completely locked, and the cooking safety is improved; one of the upper and lower coupling portions may be provided in a floating manner.

In the conventional split pressure cooking appliance, the locking cover 202 with the locking structure 203 is directly fixed on the pot cover, the locking cover 202 cannot rotate relative to the outer cover 201, and when the locking or unlocking is performed, the whole pot cover needs to be rotated to drive the locking structure 203, and the locking cover 202 can rotate to complete the locking, so that the upper coupling part 302 and the lower coupling part 301 can be coupled, and the upper coupling part 302 arranged on the outer cover 201 also needs to rotate along with the rotation of the pot cover, and then can be coupled with the lower coupling part 301 on the pot body. Generally speaking, the lower coupling portion 301 is disposed at the locking position of the pot body, when the pot cover is covered on the pot body, the upper coupling portion 302 is at the unlocking position a, there is a certain radian or angle interval between the two, the upper coupling portion 302 needs to rotate along with the rotation of the pot cover, and gradually moves towards the lower coupling portion 301 quickly, when the pot cover is locked in place, the upper coupling portion 302 already has kinetic energy with indefinite magnitude (some users have large screwing force and some have small force), when being matched with the lower coupling portion 301, a huge impact force is generated, so that the friction of the coupler is intensified, the PIN is bent and deformed, the service life is shortened, and finally, the problems of poor contact between the upper coupling portion and the lower coupling portion, ineffective electric conduction, even ignition and the like are caused.

In order to solve the above problem, the locking cover 202 is rotatably disposed in the outer cover 201 relative to the outer cover 201; as shown in fig. 2-3, the cover is covered on the pot body, the upper coupling portion 302 is matched with the lower coupling portion 301, the outer cover 201 is fixed in a limited manner relative to the pot body, the locking cover 202 is rotated, and the locking structure 203 and the locking structure 101 are switched between an unlocking position a and a locking position b.

In this embodiment, the lower coupling portion 301 is still disposed at the locking position b of the pot body, but the locking cover 202 with the locking structure 203 can be rotatably disposed relative to the outer cover 201, so that the upper coupling portion 302 will not rotate with the rotation of the locking structure 203, and can be separated from the locking action, and only participate in the closing action, so that the closing action of the split pressure cooking appliance can be simplified, i.e. the rotation action is cancelled, and only the upper and lower closing actions are performed, and considering from the degree of freedom, assuming that the height direction of the pot body is the Z axis, the pot cover of the conventional pressure cooking appliance has two degrees of freedom when being closed, one is the moving degree of freedom along the Z axis direction, and the other is the rotating degree of freedom around the Z axis direction, in this embodiment, the locking cover 202 and the outer cover 201 are separately disposed, therefore, the outer cover 201 only needs to complete the closing action, and the rotating degree of freedom around the Z axis direction can be omitted, at this moment, when the outer cover 201 is closed, the upper coupling portion 302 is also located at the unlocking position a, the outer cover 201 does not need to rotate, the upper coupling portion 302 and the lower coupling portion 301 can be matched only by aligning the upper coupler and the lower coupler, so that the distance of the matching motion between the upper coupling portion 302 and the lower coupling portion 301 is greatly reduced compared with the traditional matching mode, the problems that the upper coupling portion and the lower coupling portion of the pressure cooking appliance are relatively far and the kinetic energy is overlarge are solved, and the impact between the couplers can be relieved.

When the cover is closed, the locking cover 202 is rotated to enable the locking structure 203 to be at the unlocking position a, and the locking structure 203 and the locking structure 101 complete the alignment and matching, thereby ensuring that after the cover is closed, the locking cover 202 can rotate to the locking position b relative to the outer cover 201 to complete the locking action with the locking structure 101, because the upper coupling part 302 and the lower coupling part 301 complete the matching when the cover is closed, and the locking cover 202 needs to complete the locking action after the cover is closed, although the locking cover 202 can be rotatably arranged relative to the outer cover 201, because the locking cover 202 is still fixed on the pot cover, during the locking action, due to the interaction relationship of forces, the torque generated by the rotation of the locking cover 202 will enable the outer cover 201 to be influenced by the interaction force, and generate a movement trend, so in order to reduce the adverse influence of the locking action on the upper coupling part 302 and the lower coupling part 301, during the cover closing, the outer cover 201 is fixed on the pot body in a limiting mode, so that the outer cover is locked in a rotating limiting mode, the movement trend can be eliminated when the locking cover 202 rotates relative to the outer cover 201, and the problems that the contact between the upper coupling part and the lower coupling part is poor and the PIN needle is deformed due to the tangential force caused by the movement trend are solved; in conclusion, the plug-in type coupler arranged between the pot cover and the pot body can greatly reduce the impact of the pot cover during locking and prolong the service life.

The locking structure 203 can be arranged on a locking ring, the locking cover 202 and the locking ring are made of metal materials and can resist pressure, so that cooking safety is guaranteed, and the outer cover 201 is an injection molding part and used for installing the locking cover 202. The locking ring is annular, and the middle part is hollow.

In this embodiment, when the locking structure 203 is locked with the locking structure 101, the upper coupling portion 302 is electrically connected to the lower coupling portion 301. In order to ensure the safe operation of pressure cooking, the traditional pressure cooking appliance is provided with a sensor for detecting the closing of a cover to identify whether a pot cover is locked in place, if a reed switch is arranged at a locking position b of the pot body, a magnet is arranged on the pot cover and rotates along with the rotation of the pot cover, and when the locking position b is reached, the reed switch is closed to output a signal, and at the moment, a heating device can normally heat, so that the safe operation of cooking is ensured.

In this embodiment, the outer cover 201 is separated from the locking action and does not participate in the locking action, so that in the using process, it is no longer possible to identify whether the locking structure 203 is locked in place by detecting the position of the outer cover 201. Therefore, when the locking structure 203 is locked with the locking structure 101, the upper coupling portion 302 is electrically connected with the lower coupling portion 301, so that the heating cooking can be performed only after the locking structure is locked in place, and the safety of the pressure cooking can be ensured.

In some alternative embodiments of this embodiment, the upper coupling portion 302 may be electrically connected to the lower coupling portion 301 when the rotation of the outer cover 201 is locked by the pot body. The invention is not limited in this regard.

In this embodiment, in order to realize that the locking structure 203 is associated with the coupler when locked in place, the locking cover 202 is provided with an actuating member 204, and the actuating member 204 moves along with the rotation of the locking cover 202; meanwhile, the upper coupling portion 302 is provided on the cover 201 to be vertically floatable, and the actuator 204 is engaged with the upper coupling portion 302 to press or float the upper coupling portion 302 downward.

As shown in FIG. 3, since the upper coupling portion 302 is arranged in a floating manner, when the outer lid 201 is closed, the upper coupling portion and the lower coupling portion are actually only aligned, and the PIN PINs inside the upper coupling portion and the lower coupling portion are not inserted, so that the impact resistance between the upper coupling portion and the lower coupling portion is further improved, and because even though a certain impact force still exists due to the relative movement between the outer lid 201 and the pan body when the outer lid is closed, the impact force does not substantially affect the key structure inside the coupler, so that the service life of the upper coupling portion and the service life of the lower coupling portion can be further prolonged.

The upper coupler capable of being pressed and floated can be incompletely plugged after unlocking, and the upper coupler and the lower coupler can not be distorted and deformed due to opening and closing actions of the pot cover when the cover is opened. Preferably, the lower coupling part is arranged at the rear side of the pot body, so that the waterproof requirement on the upper coupling part can be reduced.

The actuator 204 is arranged to realize the mutual association between the locking structure 203 and the coupler, as shown in fig. 5, the actuator 204 acts on the upper coupling portion to press down the upper coupling portion 302, when the upper coupling portion 302 is pressed down, the upper coupling portion 302 and the lower coupling portion 301 are inserted into each other, and the PIN inside the upper coupling portion 302 and the PIN inside the upper coupling portion 301 are electrically connected, so that the electric conduction between the pot body and the pot cover is completed, and the heating device of the pot body can normally heat and cook only after receiving a signal that the upper coupling portion 302 and the lower coupling portion 301 are conducted, thereby ensuring the safety of pressure cooking. When the upper coupling part 302 floats upwards, the upper coupling part 302 and the lower coupling part 301 are disconnected with each other and are not conducted, at the moment, the heating system of the pot body does not continue to heat, so that the food in the inner container does not boil to generate steam, the pressure cannot continue to rise, and the cooking safety is further ensured.

The pressing and floating of the upper coupling portion 302 can be achieved in different ways, in this embodiment, as shown in fig. 8, the upper coupling portion 302 has a connector body 303 and an elastic member 304, the connector body 303 is fixed on the outer cover 201 through the elastic member 304, when the actuator 204 acts on the upper coupling portion 302, the elastic member 304 will be compressed under the action of the actuator 204, so that the connector body 303 is pressed down to be electrically connected with the lower coupling portion 301 of the pot body. When the actuator 204 no longer acts on the upper coupling portion 302, the elastic member 304 drives the upper coupling portion 302 to float up, thereby disconnecting the upper coupling portion 302 from the lower coupling portion 301.

The connector body 303 of the upper coupling portion 302 is internally provided with a PIN 305 (PIN) for realizing plugging, the connector body 303 of the lower coupling portion 301 is provided with a jack 306, the PIN 305 and the jack 306 are matched in a plugging manner along the height direction of the cooker body, so as to realize the electric connection of the cooker body and the cooker cover, the number of the PIN 305 is 2, one of the PIN 305 is a positive pole, the other PIN is a negative pole, the positive pole is responsible for the supply of the electric energy of the cooker cover and is also responsible for the transmission of signals, the two PINs 305 are adopted to improve the shock resistance of the coupler, and the PINs 305 are too many to ensure that the PINs 305 are completely matched in a plugging manner. Of course, in some alternative implementations, the number of the pins 305 may be multiple, such as 3 (adding ground lines), 4 (adding ground lines, signal lines), etc., which is not limited by the invention.

Compared with other types of electric connectors, the plug-in type coupler has the advantages of lower communication cost, convenience in power supply and easiness in control.

The pot cover is provided with a plug hole, the upper coupling part 302 is arranged in the plug hole and can float up and down in the plug hole, two sides of the upper coupling part 302 are provided with fixing lugs 307, the outer cover 201 and the fixing lugs 307 are provided with fixing protrusions 308, the elastic piece 304 is positioned on the fixing protrusions 308 and limited between the outer cover 201 and the upper coupling part 302 by the fixing lugs 307, so that the upper coupling part 302 can float up and down, the outer cover 201 is provided with a fixing column 309, the fixing lugs are limited on the outer cover 201 through a gasket 311 of a screw 310, and the screw 310 is connected with the fixing column 309.

In an alternative embodiment of the present embodiment, the upper coupling portion 302 may be disposed by other fixing schemes, which is not limited in the present invention.

A limit structure is arranged between the pot body and the outer cover 201 so as to limit and lock the rotation of the outer cover 201. Due to the existence of the limiting structure, the pot cover cannot rotate relative to the pot body after being completely covered, so that the movement trend generated by the locking structure 203 cannot cause adverse effects on the upper coupler and the lower coupler during locking action. Specifically, as shown in fig. 6 and 7, the limiting structure includes a limiting post 102 and a limiting hole 205, the limiting post 102 and the limiting hole 205 are vertically matched, and can be disposed on the outer cover 201 or on the pot body, that is, the limiting post 102 and the limiting hole 205 are respectively disposed on one of the pot body and the outer cover 201, for the convenience of alignment and the convenience of taking and placing the pot cover, the limiting post 102 is disposed on the pot body, and the limiting hole 205 is disposed on the outer cover 201, of course, in some alternative embodiments, the limiting hole 205 can also be disposed on the pot body, and the limiting post 102 is disposed on the outer cover 201.

The pot cover is characterized in that the front side and the rear side of the pot body are respectively provided with a limiting column, correspondingly, the front side and the rear side of the pot cover are also provided with a limiting hole, and the front side and the rear side are respectively provided with a limiting column and a limiting hole, so that the pot cover is not easy to incline in the process of opening the cover; can not turn on one's side and can not turn round bad when uncapping about the coupling of coupling portion, can protect the contact pin and be difficult to the distortion, improve life.

The limit structure can also be other limit structures, for example, through magnetism location structure of inhaling between the outer cover 201 and the pot body to can avoid stretching out or sunken shaping has relevant structure on the pot body or outer cover 201, can keep whole outer cover 201 and the pot body partial surfacing of mutually supporting, in order to conveniently clear up.

According to the relative position relationship between the upper coupling portion 302 and the lower coupling portion 301, predetermined positions of the upper coupling portion 302 can be defined, and the predetermined positions include a conducting position where the upper coupling portion 302 and the lower coupling portion 301 are conducting when the locking structure 203 is locked, as shown in fig. 4-5, and a disconnecting position where the upper coupling portion 302 and the lower coupling portion 301 are disconnected when the locking structure 203 is unlocked, as shown in fig. 3-4. Generally, the actuator 204 can drive the upper coupling portion 302 to switch between the on position and the off position, but in some embodiments, the predetermined position can be more.

As shown in fig. 5, in order to make the upper coupling portion 302 have a small impact force when changing the predetermined position, the actuator 204 has a guide portion 206 and a stopper portion 207, the upper coupling portion 302 is fixed at the predetermined position of the outer cover 201 when being positioned at the stopper portion 207, and the upper coupling portion 302 changes the predetermined position by the guide portion 206.

As shown in fig. 16, the locking structure 203 cannot accurately limit the upper coupling portion 302 at a predetermined position during the locking process, due to inertia of the movement, the actuator 204 will move back, so that the position-limiting platform and the upper coupling portion 302 are easily misaligned, the upper coupling portion 302 cannot be limited at a predetermined position, so that the upper coupling part 302 and the lower coupling part 301 cannot stably maintain the energized state therebetween, in order to keep the upper coupling part 302 at a predetermined position and avoid the upper coupling part 302 from being dislocated with the limiting platform, a stop limiting part and a stop matching part are arranged between the upper coupling part 302 and the lower coupling part 301, the stop limiting part and the stop matching part are respectively arranged on one of the limiting part 207 and the upper coupling part 302, the stop limiting part is matched with the stop matching part, so that the upper coupling part 302 and the limiting part 207 are in a preset position. In this embodiment, the stop limit portion 228 is disposed on the upper coupling portion 302, the stop engagement portion 229 is disposed on the limit portion 207, the stop limit portion 228 is a rib, and the stop engagement portion 229 is a groove, so that when the actuator 204 rotates to the locking position b, the rib and the groove will engage together to prevent the actuator 204 from moving relative to the upper coupling portion 302, thereby ensuring the electrical connection reliability between the upper coupling portion 302 and the lower coupling portion 301.

Of course, in some embodiments, as shown in fig. 10a, the stopping position-limiting portion 228 is a second magnetic element 209 disposed on the upper coupling portion 302, and a first magnetic element 208 disposed on the position-limiting portion 207, when the upper coupling portion 302 and the position-limiting portion 207 act, the first magnetic element 208 and the second magnetic element 209 attract each other, so that the stopping position between the upper coupling portion 302 and the position-limiting portion 207 can be achieved.

In addition, in some embodiments, if the floating upper coupling portion 302 is desired to be reliably connected, the amount of the pressing displacement of the upper coupling portion 302 is required to reach the desired value, and the detection of the locked position is triggered by the power-on, but it is possible that the pin 305 and the socket 306 are just contacted and not completely pressed, so that a further pressing is required to ensure reliable electrical connection.

Because the upper coupling portion 302 is pressed down by rotating the locking structure 203, if the reliability of the power-on is to be ensured, the pressing-down amount of the upper coupling portion 302 is to be ensured to be large enough, the pin 305 and the jack 306 cannot be just contacted at the end position of the stroke of the locking structure 203, otherwise, the reliability of the power-on cannot be ensured; if the accuracy of the cover closing detection is required to be ensured, the power is supplied when the locking structure 203 is locked in place, that is, the power of the coupler is ensured to be just supplied when the locking structure 203 is at the end position of the stroke; it can be seen that these two problems are contradictory and on opposite sides.

In some embodiments, the upper coupling portion 302 can be further pressed down when the locking structure 203 is not rotated, which is achieved by providing the first magnetic attraction member 208 and the second magnetic attraction member 209, and using the principle of like magnetic repulsion to further press down the coupler, so that the pin 305 and the socket 306 of the coupler can be completely inserted, and the reliability of the electrical connection can be ensured.

As shown in fig. 10b, the predetermined position includes that when the upper coupling portion 302 is limited to the first predetermined position by the limiting portion 207, the first magnetic attraction piece 208 and the second magnetic attraction piece 209 repel each other, and as shown in fig. 10c, the upper coupling portion 302 is driven to be limited to the second predetermined position. As shown in fig. 10b, when the locking structure 203 is operated to the position of the end of the stroke at the first predetermined position, the pin 305 and the socket 306 can be just powered on, and when the conduction signal is received, the heating device works, as shown in fig. 10c, at the second predetermined position, the first magnetic attraction piece 208 and the second magnetic attraction piece 209 repel each other, and the generated mutual repulsion force enables the upper coupling portion 302 to be pressed down continuously, thereby ensuring that the upper coupling portion and the lower coupling portion can be powered on reliably.
