Description of the embodiments
In order to further describe the technical means and effects adopted by the present application to achieve the preset purpose, the following detailed description refers to the specific implementation, structure, characteristics and effects according to the present application with reference to the accompanying drawings and preferred embodiments. In the following description, different "an embodiment" or "an embodiment" do not necessarily refer to the same embodiment. Furthermore, the particular features, structures, or characteristics of one or more embodiments may be combined in any suitable manner.
As shown in connection with fig. 1-3. The frying and baking machine comprises a lower baking tray assembly 1 and an upper baking tray assembly 2 arranged above the lower baking tray assembly 1; the lower baking tray assembly 1 comprises a lower shell 11, an upper shell 12 fixed at the upper end of the lower shell 11 and a lower baking tray 14 arranged in the center of the upper shell 12, wherein a first heating body 15 (for example, the first heating body 15 is an electric heating tube or an electric heating wire) is arranged on the lower side surface of the lower baking tray 14. The upper baking tray assembly 2 comprises a top cover 21, an upper baking tray 22 arranged below the top cover 21 and a second heating body 23 (for example, the second heating body 23 is an electric heating tube or an electric heating wire) arranged on the upper side surface of the upper baking tray 22; the lower baking tray 14 is arranged opposite to the upper baking tray 22, and a frying cavity 3 for placing food for frying and cooking is arranged between the upper side surface of the lower baking tray 14 and the lower side surface of the upper baking tray 22; at least 2 first shaft holes 121 are provided on the peripheral side of the upper case 12, and a push rod 51 is provided in each of the first shaft holes 121, and an upper end of the push rod 51 is located directly below the top cover 21 so as to be in contact with a lower side surface of the top cover 21 when the push rod 51 is lifted; and a driving device for adjusting the height of the frying and baking cavity 3 by driving the ejector rod 51 to lift, wherein the driving device is positioned in the lower baking tray assembly 1.
Wherein, the lower baking tray assembly 1 is rotatably hinged with the upper baking tray assembly 2. In one embodiment, one of the upper shell 12 of the lower tray assembly 1 and the upper shell 12 of the upper tray assembly 2 is provided with a hinge seat 16 and the other is correspondingly provided with a hinge pin 24, the hinge seat 16 is provided with a hinge hole, and the hinge pin 24 is positioned in the hinge hole of the hinge seat 16 to realize rotatable hinge of the upper tray assembly 2 relative to the lower tray assembly 1, as shown in fig. 1. For example, the hinge base 16 is provided at one of the upper sides of the upper case 12, and the hinge pin 24 is provided at one of the lower sides of the top cover 21, and the hinge base 16 is positioned opposite to the hinge pin 24 so that the hinge pin 24 is hinged in the hinge hole of the hinge base 16.
The hinge hole of the hinge base 16 is a kidney-shaped vertical groove. It will be appreciated that the height of the kidney-shaped vertical slot matches the maximum adjustable height H of the fry roaster chamber 3. As shown in fig. 3, when the upper tray assembly 2 is not lifted by the lift pins 51, the height of the frying cavity 3 is a predetermined height a (the predetermined height a is 3-5mm, which is preferable for the frying cavity 3 to meet the requirements of frying the wafer), and at this time, the hinge pin 24 is located at the bottom of the hinge hole, i.e., the hinge pin 24 is located at the bottom of the kidney-shaped vertical groove. Conversely, when the height of the upper baking tray assembly 2 jacked by the ejector rod 51 reaches the maximum adjustable height H (H is generally 3-5cm or more to meet the baking requirements of baking the foods with larger thickness such as steamed stuffed buns, spareribs, chicken wings and the like), the height of the baking cavity 3 reaches the maximum height a+h, and the hinge pin 24 is positioned at the top of the hinge hole, namely, the hinge pin 24 is positioned at the top of the kidney-shaped vertical groove. Therefore, the maximum adjustable height H of the frying and baking cavity 3 is matched by arranging the hinge holes of the hinge base 16, so that the rotatable hinged connection between the upper baking tray assembly 2 and the lower baking tray assembly 2 when the frying and baking cavity 3 is at different heights is met.
For convenient operation, a handle 28 is arranged on the upper side surface of the top cover 21, which is far away from the side edge of the hinge pin 24, so that a user can conveniently rotate the upper baking tray assembly 2 relative to the lower baking tray assembly 1 through the handle 28 in the process of the frying, baking and cooking operation so as to take and put food in the frying, baking cavity 3.
A concave hinge groove 17 is arranged on the upper end surface of the hinge seat 16, and a hollow sleeve 25 is arranged on the lower side surface of the top cover 21 corresponding to the position of the hinge groove 17. One end of a power wire 41 with a socket is fixedly installed in the lower baking tray assembly 1 through a pressing plate 42 and is electrically connected with the first heating body 15, and the power wire 41 also passes through the hollow sleeve 25 and then enters the upper baking tray assembly 2 to be electrically connected with the second heating body 23. Food is placed in the frying and baking cavity 3, the upper surface and the lower surface of the food are respectively contacted with the lower baking tray 14 and the upper baking tray 22, the first heating body 15 is electrified to generate heat to be transferred to the lower baking tray 14 so as to enable the lower baking tray 14 to fry and bake the lower surface of the food, the second heating body 23 is electrified to generate heat to be transferred to the upper baking tray 22 so as to enable the upper baking tray 2 to fry and bake the upper surface of the food, and the upper baking tray 22 and the lower baking tray 14 are used for simultaneously frying and baking the upper surface and the lower surface of the food so as to improve frying and baking cooking efficiency.
In addition, the lower baking tray 14 and the upper baking tray 22 are both round or oval, and the lower baking tray 14 and the upper baking tray 22 are arranged opposite to each other so that the frying and baking cavity 3 is round or oval. Correspondingly, the top cover 21 of the upper baking tray assembly 2 is round, elliptic, square or rectangular with chamfer angles; the size of the upper shell 12 is larger than that of the top cover 21, an operation panel 13 is arranged on the side edge of the upper shell 12 opposite to the hinge seat 16, and when the upper baking tray assembly 2 is covered on the lower baking tray assembly 1, the operation panel 13 is exposed out of the top cover 21 so as to be convenient for a user to operate and use. The operation panel 13 is generally provided with corresponding keys for setting the frying time and the frying power (fire), and the like, and the technical knowledge of how to electrically connect and how to mutually cooperate the operation panel 13, the power line 41, the first heating element 15 and the second heating element is known to those skilled in the art and will not be repeated herein.
Further shown in connection with fig. 3-7. The driving device is positioned in the lower baking tray assembly 1, and the ejector rod 51 is driven by the driving device to ascend or descend so as to enable the upper baking tray assembly 2 to ascend or descend relative to the lower baking tray assembly 1, thereby achieving the operation purpose of correspondingly increasing or decreasing the height of the frying and baking cavity 3.
Specifically, the driving device includes a rotating cam 64 and an adjusting mechanism that drives the rotating cam 64 to rotate; the rotating cam 64 is rotatably limited in the lower baking tray assembly 1, the rotating cam 64 is provided with a plurality of inclined protruding blocks 641 extending upwards, and the upper end surface of each inclined protruding block 641 is provided with inclined surfaces with consistent inclination and same inclination direction (the inclined surfaces comprise cambered surfaces in the application). The lower end of each ejector rod 51 is fixedly provided with a sliding support plate 53, the sliding support plate 53 may be integrally formed with the ejector rod 51 or be an integral part of the ejector rod 51, and the lower side surface of the sliding support plate 53 is in contact with the upper end surface of the inclined projection 641 corresponding to the position, so that the lower side surface of the sliding support plate 53 is preferably an inclined surface with the inclination consistent with the inclination of the upper end surface of the inclined projection 641. Therefore, when the rotating cam 64 is driven to rotate by the adjusting mechanism, the upper end surface of each inclined lug 641 is respectively connected with the lower side surface of one of the sliding support plates 53 in an inclined contact manner, so that each inclined lug 641 drives each ejector rod 51 to synchronously ascend or descend through the corresponding sliding support plate 53.
Taking the view of fig. 6 as an example, how the rotation of the rotating cam 64 drives the lift pins 51 to rise and fall will be further described. In the embodiment shown in fig. 6, 3 inclined protrusions 641 are uniformly distributed on the upper side of the rotating cam 64, the upper end surface of each inclined protrusion 641 is inclined in the same direction and is set to be an ascending inclined surface in the clockwise direction, and the inclination of the upper end surface of each inclined protrusion 641 is uniform. Correspondingly, the number of the ejector rods 51 is 3, and the lower end of each ejector rod 51 is connected with the upper end face of one inclined lug 641 through inclined surface contact by a sliding supporting plate 53. Therefore, when the rotating cam 64 rotates clockwise, the sliding support plate 53 moves upwards from the bottom end of the upper end surface of the inclined lug 641, so that the inclined lug 641 applies an upward force to the sliding support plate 53, and the upward force pushes the ejector rod 51 to perform an upward movement through the sliding support plate 53, so that the ejector rod 51 performs an axial upward movement with the first shaft hole limit, and the upper end of the ejector rod 51 pushes up the upper baking tray assembly 2 to increase the height of the baking cavity 3; when the sliding support plate 53 is located at the top end of the upper end surface of the inclined protrusion 641, the top rod 51 is lifted by the height H to raise the height of the frying and baking chamber 3 by the maximum adjustable height H from the preset height a, and the height of the frying and baking chamber 3 reaches the maximum height a+h as shown in fig. 7. Conversely, when the rotating cam 64 rotates anticlockwise, the contact position between the upper end surface of the inclined lug 641 and the sliding support plate 53 is continuously lowered, so that the inclined lug 641 does not generate upward acting force on the sliding support plate 53 any more, and the sliding support plate 53 drives the ejector rod 51 to correspondingly move downwards along with the anticlockwise rotation of the inclined lug 641; until the sliding support plate 53 returns to the bottom end of the upper end surface of the inclined projection 641, the ejector rod 51 no longer has a supporting effect on the upper baking tray assembly 2, the upper baking tray assembly 2 is completely covered on the lower baking tray assembly 1, and at this time, the height of the frying and baking cavity 3 is restored to the preset height a, namely, the state shown in fig. 3.
In order to improve the contact reliability between the sliding support plate 53 and the upper end surface of the inclined projection 641, an elastic portion 52 is provided at the lower end of the ejector rod 51, and the elastic portion 52 is pressed against the lower end of the ejector rod 51 to press the ejector rod 51 against the upper end surface of the inclined projection 641. For example, the elastic portion 52 is a return spring that is provided around the lower end of the ejector pin 51 and is located between the lower side surface of the upper case 12 and the slide plate 53. Even, a chute is provided at the lower side of the sliding tray 53, the upper end surface of the inclined projection 641 is positioned in the chute, and the inclined projection 641 is limited by the chute to slide relative to the sliding tray 53.
In addition, the push rods 51 are ensured to move smoothly in the lifting movement process without deflection or clamping stagnation, so that the lifting operation is smooth and simple, and the heights of all parts of the frying and baking cavity 3 are ensured to be consistent all the time so as to ensure the cooking quality of frying and baking. First, the lower side of the upper shell 12 is provided with a limiting skirt 122, the limiting skirt 122 is located on the periphery of the first shaft hole 121, and the limiting effect of the first shaft hole 121 on the ejector rod 51 is enhanced through the limiting skirt 122. Secondly, ensure that rotatory cam 64 rotates smoothly and can not take place the part upwarp in the rotation in-process, therefore, be equipped with solid fixed ring 111 and annular boss 124 in lower overware subassembly 1, rotatory cam 64 is located solid fixed ring 111 with by solid fixed ring 111 provides the support to rotatory cam 64, the lower extreme of annular boss 124 has annular groove, rotatory cam 64's medial edge is located annular groove, thereby let rotatory cam 64 regard solid fixed ring 111 as the support and rotate with annular groove spacing of annular boss 124, thereby rotatory cam 64 has been avoided taking place the part upwarp in the rotation in-process and has been kept synchronous upgrading motion for guaranteeing each ejector pin 51 and has provided the realization condition.
There are various ways in which the fixing ring 111 and the annular boss 124 are fixed in the lower tray assembly 1. For example, the fixing ring 111 is fixed to the upper side of the lower case 11, the annular boss 124 is fixed to the fixing ring 111, or the annular boss 124 is fixed to the lower side of the upper case 12, and the fixing ring 111 is fixed to the lower side of the annular boss 124.
And, a sliding groove is provided at one of the lower side of the rotating cam 64 and the upper side of the fixing ring 111, and the other is provided with a sliding rail, the sliding rail is provided in the sliding groove, so that the fixing ring 111 provides support for the rotating cam 64 and allows the rotating cam 64 to rotate on the fixing ring 111 according to the cooperation of the sliding rail and the sliding groove.
Furthermore, there are various ways of implementing the adjustment mechanism. For example, the adjusting mechanism is a motor, a transmission shaft of the motor is coaxially connected with the rotating cam 64, and the rotating cam 64 is driven to rotate by the motor. However, the motor is relatively expensive to implement, and for this purpose, the invention preferably employs a manually operated adjustment mechanism comprising a knob 61, a transmission shaft 62, a transmission gear 63 and a sector gear 65, the sector gear 65 being fixed to the inner or outer side of a rotary cam 64, the transmission gear 63 being in meshed connection with the sector gear 65, the transmission shaft 62 being connected between the knob 61 and the transmission gear 63. Wherein, a second shaft hole is arranged on the upper shell 12, and a transmission shaft 62 passes through the second shaft hole and is fixedly connected with a knob 61 positioned outside the upper shell 12; and the lower shell 11 is provided with a gear seat 66, and the transmission gear 63 is limited on the gear seat 66. Therefore, when the knob 61 is turned, the transmission gear 63 is driven to rotate at the same angular velocity by the transmission shaft 62, and the rotating cam 64 is driven to rotate by the sector gear 65, so that the push rod 51 can be lifted or lowered correspondingly by selecting the turning direction of the knob 61.
The knob 61 is disposed near the side of the operation panel 13 opposite to the hinge seat 16 of the upper housing 12, and the knob 61 and the operation panel 13 are disposed in a concentrated position to facilitate the operation of a user. Furthermore, an indication part 611 is provided at the position of the upper housing 12 near the knob 61 or at the upper end surface of the knob 61, wherein the indication part 611 includes an indication of the rotation direction required for adjusting the knob 61 when increasing and decreasing the height of the frying and baking cavity 3, or/and an indication of the rotation angle required for correspondingly indicating the knob 61 when increasing or decreasing the different heights of the frying and baking cavity 3. The indication portion 611 is an indication label fixed to the surface of the upper case 12 by adhesion, printing, or the like. Therefore, the user can clearly and conveniently select the direction and the rotation angle of the rotation knob 61 according to the indication of the indication part 611 so as to accurately adjust the height of the frying and roasting cavity 3 to the required position, and the operation is simple, convenient and quick.
The foregoing description of the preferred embodiments of the present application is not intended to be limiting, but is intended to cover any and all modifications, equivalents, and alternatives falling within the spirit and principles of the present application.
