Cooking apparatus

Technical Field

The present invention relates to a cooking apparatus; more particularly, the present invention relates to a cooking apparatus for cooking.

Background

The pan turning is one of the most common and basic cooking actions in Chinese cooking, has good pan turning effect, can ensure even heating of materials and consistent maturity, thereby ensuring the quality of dishes. In traditional Chinese cooking, a cook usually operates a pot to perform a 'lifting and raising' periodic motion, and controls the pot to generate rapid deceleration/rapid acceleration in the motion process, so that cooked materials in the pot are thrown up along the edge of the pot and fall into the pot after being turned over. The pot turning device has the advantages that the pot turning force is controlled according to needs, large turning and small turning can be achieved respectively, most or all materials in a pot are turned over at one time during large turning, the action amplitude and the force are large, the materials are thrown up to a high height, the proportion that the materials are turned over at one time during small turning is small, the action amplitude and the force are small, and the thrown-up height of the materials is low.

Most of the existing automatic or semi-automatic cooking equipment realizes the effect of turning a pot by simulating the motion mode of the pot during manual cooking. For example, chinese patent CN200910105771.6 discloses an automatic or semi-automatic pot-turning device and a cooking apparatus using the same, wherein the pot-turning device includes a base, a first swing rod and a swing mechanism, the end of the first swing rod is hinged to the base, the top end of the first swing rod is connected to a pot, the swing mechanism is mounted on the base, and the swing mechanism is driven by a driving device to drive the first swing rod to make reciprocating swing motion, so as to drive the pot to make reciprocating swing motion.

For another example, chinese patent application CN201410076906.1 discloses an automatic pot-turning system, which includes: a frame; a pan for cooking; a pot driving device; the pot supporting block is fixedly arranged on the rack, is positioned below the pot and within the pot edge range, and is contacted with the pot; wherein, pan drive arrangement drive pan reciprocating motion makes the contact point of pan tray and pan periodically change on the pan, and this contact point takes place the displacement of vertical direction for the pan when taking place the horizontal direction displacement to the manual pot turning action of carrying and sending up of accomplishing of cook.

The disadvantages of the above prior art solutions are: the pot turning mechanism has the advantages that the consistency of the motion performance of the mechanism is poor, pot turning is realized completely depending on the motion of a pot, the requirement on the control precision of the pot motion is extremely high, the change of damping (such as different damping caused by abrasion, oil stain and the like after assembly and long-time operation) of the mechanism is very sensitive, and when the quantity of cooking materials is changed, the motion parameters of the pot are generally required to be adjusted, otherwise, the problems that the materials fall out of the pot or cannot be effectively turned over are easily caused in the pot turning process; secondly, because the pan usually has great weight, therefore this kind of mode of realizing turning over the pot through the motion of pan has that equipment energy consumption is high, fragile, and the in-process vibration of turning over the pot and noise are big etc. defect.

Disclosure of Invention

In view of the shortcomings of the prior art, the present invention is directed to a cooking apparatus that achieves a pan-turning effect through cooperation of a pan-turning member and a pan.

In order to achieve the above object, the present invention provides a cooking apparatus comprising:

the cookware comprises a cookware body and a turning part extending upwards from the cookware body; the turning part can be integrated with the cooker body and can also be fixed to the cooker body through welding or other connecting means;

the stir-frying mechanism comprises a stir-frying power device and a stir-frying component; wherein, the working end of the stir-frying component is matched with the inner wall of the cooker, and the stir-frying component is driven by the stir-frying power device to move from the cooker body to the back-turning part along the inner wall of the cooker.

In the invention, all or part of the working end of the stir-frying component can be in direct contact with or closely adjacent to the inner wall of the pot, and can be formed into a wedge shape, a strip shape or a triangle shape which is convenient for pushing and pulling materials, thereby being capable of better driving the materials to move. In addition, the working end of the stir-frying component or other parts connected with the working end can have proper elasticity, so that the working end of the stir-frying component is elastically abutted against the inner wall of the cooker, and the mutual interference between the working end of the stir-frying component and the inner wall of the cooker is avoided.

In the present invention, the inner wall of the turning-back part may be formed as a plane and/or a curved surface extending upward as long as it can guide the material to move toward the inside of the pot during the cooking process. In the cooking process, under the driving of the stir-frying component and/or the inertia effect generated by the stir-frying component, the materials move upwards to the reverse turning part along the inner wall of the pot body, fall back to the inside of the pot under the guiding of the reverse turning part and turn over (turn over) in the process, so that the pot turning effect is realized. Wherein, the inner wall of the turning part is preferably formed into a curved surface bending towards the inner side of the pot, which has the advantages that not only can the materials be better guided to fall back to the bottom of the pot serving as the main heating area in the cooking process, but also better material turning effect can be realized.

Therefore, the cooking equipment realizes the pan-turning effect through the matching of the stir-frying component and the pan, does not need to control the pan to simulate the complex motion of manually turning the pan by a cook, and can effectively reduce the cooking energy consumption. In addition, the materials can not fall out of the cooker basically because the materials move towards the inside of the cooker under the guiding action of the turning-back part in the cooking process.

According to an embodiment of the invention, the working end of the stir-frying member is driven by the stir-frying power device to move from the pot body to the turning-back part. In the invention, although the material can move to the turning-back part by means of the self movement inertia under the condition that the working end of the stir-frying component does not move to the turning-back part (for example, the working end of the stir-frying component moves to the joint of the pot body and the turning-back part), and the turning-back is realized by the guidance of the turning-back part, the speed is reduced when the material moves to the turning-back part, so that the material mainly falls to the area close to the turning-back part, and the utilization efficiency of heat and the heating uniformity of the material are both insufficient. The working end of the stir-frying component is controlled to move to the back-turning part, so that the material still has a higher moving speed when moving to the back-turning part, can mostly or basically fall back to the bottom of the pot serving as a main heating area under the action of inertia, is more uniformly distributed in the pot, reduces the dry burning of the pot, and greatly improves the utilization efficiency of heat and the heating uniformity of the material.

According to another embodiment of the invention, the inner contour of the cross section of the pot body comprises a first circular arc, and the inner contour of the cross section of the turning part extends within the range of the circle of the first circular arc and inclines or bends towards the inner side of the pot, so as to effectively reduce the volume of the pot. In addition, the inner contour of the cross section of the cooker body comprises a first arc (namely, the inner wall of the cooker body is provided with a cambered surface), so that the heating area of the cooker body is large, and the cooking equipment can realize a stir-frying process.

In a more specific embodiment of the invention, the inner contour of the cross section of the turned-back portion includes a second circular arc inscribed in the first circular arc, so as to simplify the structure of the pot and facilitate the preparation thereof. Preferably, an included angle between a free end point of the second arc (i.e. an end point of the second arc which is not connected with the first arc) and a connecting line of the circle center of the second arc and the horizontal plane is controlled to be 30-70 degrees, so that the materials are well prevented from falling out of the pot, and a better material turning effect is realized.

According to another more specific embodiment of the present invention, the stir-fry element is rotated about its axis of rotation by the stir-fry power means; meanwhile, the cooking apparatus further includes a moving mechanism that causes a relative movement between the pot and the stir-frying mechanism to prevent the pot and the stir-frying member from interfering.

In the technical scheme, the moving mechanism can drive the cooker and/or the stir-frying mechanism to move, so that the cooker and the stir-frying mechanism can move relatively. For example, a pot or stir-fry mechanism is provided on the slide member and the slide member is driven to move by electric means, magnetic means, pneumatic means, hydraulic means, or other types of power means. In a simpler embodiment of the invention, the movement mechanism comprises a first slide member arranged substantially horizontally on the machine frame and a slide drive for driving the first slide member to move, the stir-frying mechanism being arranged on the first slide member.

As an embodiment, the slider driving device includes a driving cam for pushing the first slider member, a driven roller provided on the frame, and an elastic force application element provided between the first slider member and the frame; the driving cam has a profile matched with the cooker and synchronously rotates with the stir-frying component; the elastic urging element applies an elastic urging force to the first slider member so that the driving cam and the driven roller are held in contact.

Specifically, the profile of the active cam includes a stirring section adapted to the pot body, a turning-back section adapted to the turning-back portion, and an idle section corresponding to the return stroke of the stir-frying member. In the cooking process, when the stirring section of the driving cam is contacted with the driven roller, the working end of the stir-frying component rotates along the inner wall of the pot body from the initial working position, and the first sliding block component keeps a static state; when the turning section of the driving cam is contacted with the driven roller, the working end of the stir-frying component moves along the inner wall of the turning part, and the driving cam pushes the first slide block component to translate under the counterforce exerted by the driven roller, so that the stir-frying component and the turning part are prevented from interfering; when the idle section of the driving cam contacts with the driven roller, the working end of the stir-frying component leaves the back-stirring part and returns to the initial working position. In addition, in the process that the working end of the stir-frying component moves along the inner wall of the back-stirring part, the stir-frying component simultaneously translates along with the first sliding block component, so that a better pan-stirring effect can be realized.

In the above technical solution, the driving cam is preferably arranged on the rotating shaft of the stir-frying member, which has the advantage of simple structure. In one embodiment, the driving cam may also be disposed on the slider member, and a gear transmission mechanism is disposed between the stir-frying power device and the driving cam to control the driving cam and the stir-frying member to rotate synchronously under the driving of the stir-frying power device.

According to another embodiment of the invention, the cooking apparatus further comprises a stir-frying track changing mechanism arranged between the stir-frying power device and the stir-frying member, the stir-frying track changing mechanism is used for transmitting the power of the stir-frying power device to the stir-frying member and enabling the working end of the stir-frying member to have a motion track matched with the inner wall of the pot. In general, the stir-fry trajectory transformation mechanism may employ a multi-link mechanism since the multi-link mechanism may implement a complex known motion law and trajectory in a plane/space.

Optionally, the stir-frying track changing mechanism comprises a crank member connected with the stir-frying power device, a rocker member hinged on the base, a guide rod member and a connecting seat; the guide rod component can slidably penetrate through the rocking block component, one end of the guide rod component is hinged with the crank component, and the other end of the guide rod component is fixedly connected with the connecting seat; the stir-frying component is respectively hinged with the connecting seat and the guide rod component, and a hinge point between the stir-frying component and the connecting seat is positioned above the hinge point between the stir-frying component and the guide rod component.

According to another embodiment of the invention, the pot extends in its longitudinal direction and the inner contour of its respective cross section is substantially identical. Such benefit is that not only the material has more even distribution in the vertical of pan, and the material has appropriate motion space in the vertical of pan moreover, is convenient for shake the pot.

In order to realize the pan shaking, the cooking apparatus of the present invention may further comprise a pan shaking power unit and a translation mechanism, the pan being connected to the translation mechanism, the pan shaking power unit driving the pan to reciprocate in a longitudinal direction thereof via the translation mechanism.

In the cooking equipment, although the size of the working end of the stir-frying component can be equal to the size of the inner cavity of the pot in the longitudinal direction of the pot, so that the stir-frying component can stir and fry materials in the whole longitudinal direction of the pot, the cooking equipment is easy to understand. As a preferred mode, the pan shaking is required to be carried out while the stir-frying mechanism works, so that the materials are scattered in the pan and uniformly mixed. Accordingly, the size of the working end of the stir-frying member is preferably controlled to be 1/4 to 3/4 of the size of the inner cavity of the pot in the longitudinal direction of the pot. On one hand, when the size of the working end of the stir-frying component is less than 1/4 of the size of the inner cavity of the pot, the stir-frying component can stir and fry materials in limited time, so that the pot-turning effect is poor; on the other hand, when the size of stir-fry component work end is less than 3/4 of pan inner chamber size, the translation distance of pan is less, reduces and shakes the pot effect. Furthermore, only a proper amount of materials are turned over in each working period of the stir-frying component, so that dry burning of the cooker is reduced, the heat utilization efficiency is improved, and the service life of the cooker is prolonged.

In the invention, in order to achieve a better pan shaking effect, the pan shaking power device (such as a motor) can be used for driving the pan to do unidirectional acceleration or deceleration movement, and the pan can also do unidirectional acceleration or deceleration movement by utilizing the movement characteristic of the translation mechanism.

Optionally, the translation mechanism comprises a second slider member connected to the pot, a crank member connected to the pan shaking power device, and a link member hinged to the second slider member and the crank member, respectively, the second slider member, the crank member and the link member constituting an offset crank-slider mechanism. Because the offset crank sliding block mechanism has the quick return characteristic, the cooker can do unidirectional accelerated motion under the condition that the rotating speed of the motor is not changed.

Preferably, the crank member is a rotating disc to improve the balance performance of the crank member in the rotating process, so that the translation process of the translation mechanism and the pan is more stable.

To more clearly illustrate the objects, technical solutions and advantages of the present invention, the following detailed description of the present invention is provided with reference to the accompanying drawings and the detailed description.
