For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the related art, the weight of the heating plate component arranged inside the cooking equipment is heavy, the heating plate component is extruded by the deformation of the lower cover in the falling process of the cooking equipment, the heating plate component impacts the panel, and the problem of panel breakage is easily caused.

In view of the above, the present utility model provides a cooking apparatus, which can limit the movement of the lower cover in a direction approaching to the upper cover by providing the protrusion structure, thereby preventing the problem that the heating plate assembly is impacted against the panel due to the deformation of the lower cover and the extrusion of the heating plate assembly, and reducing the damage of the panel.

The cooking apparatus provided by the embodiment of the present utility model is described below with reference to the accompanying drawings.

Referring to fig. 1 and 2, the present utility model provides a cooking apparatus comprising: the heating plate comprises a shell, a panel 30 and a heating plate assembly 40, wherein the shell comprises a lower cover 10 and an upper cover 20, the lower cover 10 and the upper cover 20 are mutually connected and jointly enclose a containing cavity 11, and the upper cover 20 is provided with a mounting hole 21; the panel 30 is disposed on the mounting hole 21; the heating plate assembly 40 is disposed in the accommodating chamber 11, and the heating plate assembly 40 is located below the panel 30. The inner wall surface of at least one of the lower cover 10 and the upper cover 20 is provided with a protrusion structure, and the protrusion structure extends toward the other of the lower cover 10 and the upper cover 20, the protrusion structure being for preventing the lower cover 10 from moving in a direction approaching the upper cover 20.

According to the cooking equipment provided by the utility model, the fact that the lower cover 10 is easy to deform in the process of transporting the cooking equipment or falling the cooking equipment to cause the heating plate assembly 40 to strike against the panel 30 to cause the damage of the panel 30 is considered, so that the lower cover 10 can be limited to move towards the direction close to the upper cover 20 by arranging the convex structure, the lower cover 10 is limited to move towards the direction close to the upper cover 20, the condition that the panel 30 is damaged due to the fact that the lower cover 10 presses the heating plate assembly 40 is avoided, and the service life of the panel 30 is ensured.

According to the cooking equipment provided by the utility model, the material of the lower cover 10 is not required to be replaced, the problem that the panel 30 is damaged due to the deformation of the lower cover 10 is solved by arranging the protruding structure, and the problem that the lower cover 10 deforms to impact the heating plate assembly 40 is solved under the condition that the material cost of the lower cover 10 is not increased, so that the cost is lower.

In one possible implementation, as shown with reference to fig. 1 and 3, the panel 30 includes units that are not limited to being glass, micro-crystalline or ceramic plates. The panel 30 may be fixedly connected to the mounting hole 21 by means of glue bonding, snap fastening, or the like.

In one possible implementation, the panel 30 may be circular or square. The shape of the mounting hole 21 is adapted to the shape of the panel 30.

In the case where the cooking apparatus is an induction cooker, as shown with reference to fig. 1 and 4, the heating plate assembly 40 may be a coil plate. In the case where the cooking device is an electric ceramic stove, the heating plate assembly 40 may be a far infrared plate. Again not to be limiting. During cooking, a cooking container such as a pot is placed on the panel 30, and the heating of food in the pot is realized through the heating plate assembly 40, so that the aim of cooking is fulfilled.

In one possible implementation, the hotplate assembly 40 may be attached to the inner bottom wall of the lower cover 10 by fasteners, including but not limited to screws, bolts, rivets, and the like. In the process of the method,

in one possible embodiment, referring to fig. 5 and 6, the protrusion structure includes a first protrusion 51 provided at an inner wall surface of the lower cover 10, and an end of the first protrusion 51 remote from the lower cover 10 extends to have a preset interval H from the inner wall surface of the upper cover 20. In this example, the first protruding member 51 may be a pillar or the like.

In one possible implementation, referring to fig. 10 and 11, the pitch H satisfies: h is more than or equal to 0 and less than or equal to 1mm. The pitch H may be 0.3mm, 0.4mm, 0.5mm, 0.8mm, or 1mm, and when the lower cover 10 is slightly deformed and moved in a direction approaching the upper cover 20, the pitch H becomes 0, and the first protruding piece 51 comes into contact with the inner wall surface of the upper cover 20.

In this example, the first protruding member 51 may directly abut against the inner wall surface of the upper cover 20, and under the supporting effect of the rigidity of the first protruding member 51, the lower cover 10 may be effectively prevented from moving in a direction approaching to the upper cover 20, so that the lower cover 10 is prevented from pressing the heating plate assembly 40 to cause the heating plate assembly 40 to impact the panel 30, and thus, the phenomenon that the panel 30 is damaged is avoided.

In another possible implementation, referring to fig. 5, 6 and 7, the bump structure includes: a first protruding piece 51 and a second protruding piece 52, the first protruding piece 51 being provided on an inner wall surface of the lower cover 10; the second protrusion 52 is provided on the inner wall surface of the upper cover 20; as shown in fig. 10 and 11, the first protruding member 51 extends to the lower side of the second protruding member 52 with a predetermined distance H between the first protruding member 51 and the second protruding member 52. The spacing H satisfies: h is more than or equal to 0 and less than or equal to 1mm.

It is easy to understand that when the distance H is too small, there is a hidden danger that the first protruding member 51 interferes with the lower cover 10 during the assembly process, which is inconvenient for production and assembly, and when the distance H is too large, the allowance that the lower cover 10 can move toward the direction close to the upper cover 20 is too large, which is unfavorable for the protruding structure to play an effective supporting and protecting role. Therefore, the present utility model satisfies the following by making the pitch H: h is more than or equal to 0 and less than or equal to 1mm, not only can meet the requirement of convenient assembly, but also can ensure that the convex structure plays an effective supporting and protecting role.

In this embodiment, by the cooperation of the first protruding member 51 and the second protruding member 52, when the preset distance H between the first protruding member 51 and the second protruding member 52 is 0, the first protruding member 51 and the second protruding member 52 abut against each other, so that the movement of the lower cover 10 in the direction approaching to the upper cover 20 can be restricted, the problem that the lower cover 10 presses the heating plate assembly 40 to cause the heating plate assembly 40 to strike the panel 30 is effectively prevented, and the damage of the panel 30 is reduced.

In one possible implementation, referring to fig. 7 and 8, the second boss 52 includes a first baffle plate 521, the first baffle plate 521 extending from the inner wall of the mounting hole 21 toward the center of the mounting hole 21; referring to fig. 5, the first protrusion 51 includes a support rib 511 provided on an inner wall of the lower cover 10, and referring to fig. 10 and 11, the support rib 511 extends to a lower side of the first barrier 521, and the support rib 511 coincides with at least a partial projection of the first barrier 521 on a horizontal plane, with a predetermined distance H between the support rib 511 and the first barrier 521.

The first barrier rib 521 may be overlapped with at least a part of the projection of the support rib 511 on the horizontal plane, so as to ensure that the support rib 511 and the first barrier rib 521 may abut against each other when the lower cover 10 is deformed in a direction approaching the upper cover 20, or the top of the support rib 511 may abut against a surface of the first barrier rib 521 facing the lower cover 10, thereby restricting the deformation of the lower cover 10.

Referring to fig. 7 and 8, the first blocking plate 521 extends from the inner wall of the mounting hole 21 toward the center of the mounting hole 21, so that the supporting rib 511 and the first blocking plate 521 are prevented from being mutually matched due to the blocking effect of the components in the accommodating chamber 11.

It will be readily appreciated that the length of the first baffle 521 need not be so long that the first baffle 521 may be brought into at least partial projection coincidence with the support rib 511 in the horizontal plane.

In one possible implementation, referring to fig. 5 and 11, the wall thickness of the support rib 511 is 1/3 to 1/2 times that of the lower cover 10. The support rib 511 is ensured to have enough strength, so that the problem that the support rib 511 is broken or deflected is prevented when the support rib 511 is abutted against the first baffle plate 521, and the support rib 511 is ensured to play a role of resisting the deformation of the lower cover 10.

In one possible implementation, the wall thickness of the ribs 511 may be 1/3, 2/5, or 1/2 times the wall thickness of the lower cover 10.

In one possible implementation, referring to fig. 7 and 8, the second protrusion 52 further includes a second barrier 522, the second barrier 522 and the first barrier 521 are spaced apart from each other at an edge of the mounting hole 21, and the second barrier 522 extends toward a center of the mounting hole 21. Referring to fig. 5, the first protruding member 51 further includes a wind shielding rib 512 disposed on an inner wall of the lower cover 10, the wind shielding rib 512 extends to a lower side of the second barrier 522, as shown in fig. 12 and 13, and at least a partial projection of the wind shielding rib 512 and the second barrier 522 on a horizontal plane coincides, and a preset distance H is provided between the wind shielding rib 512 and the second barrier 522.

The reason why the wind shielding rib 512 and the second barrier 522 are overlapped with each other in at least a partial projection on the horizontal plane is to ensure that the wind shielding rib 512 and the second barrier 522 can abut against each other when the lower cover 10 is deformed to move in the direction approaching the upper cover 20, and that the top of the wind shielding rib 512 abuts against the surface of the second barrier 522 facing the lower cover 10, thereby restricting the deformation of the lower cover 10 to move in the direction approaching the lower cover 10.

Referring to fig. 5 and 8, the second barrier 522 and the first barrier 521 are spaced apart from each other at the edge of the mounting hole 21, and the second barrier 522 and the first barrier 521 protect different positions supporting the edge of the mounting hole 21. The second baffle 522 extends toward the center of the mounting hole 21, so that the influence of the blocking effect of the components in the accommodating cavity 11 on the cooperation of the wind shielding rib 512 and the second baffle 522 can be avoided.

In one possible implementation, the first baffle 521 is made of a flame retardant material, so that the first baffle 521 has high heat resistance and flame retardant effect, and improves fireproof performance.

In one possible implementation, the second barrier 522 is a second barrier made of a flame retardant material, so that the first barrier 521 has high heat resistance and flame retardant effect, and improves fireproof performance.

Flame retardant materials include, but are not limited to, polybutylene terephthalate (polybutylene terephthalate, PBT for short), polyethylene terephthalate (Polyethylene terephthalate, PET for short), polyamide (PA for short) and heat resistant temperatures greater than 150 degrees.

In one possible implementation, referring to fig. 5 and 6, the second protrusion 52 further includes a stopper 523 provided to an inner wall surface of the upper cover 20; the first protruding element 51 further includes a water blocking rib 513 provided on the inner wall surface of the lower cover 10, the water blocking rib 513 being located at the lower side of the limiting element 523, as shown with reference to fig. 14 and 15, with a preset interval H between the water blocking rib 513 and the limiting element 523.

By providing the stopper 523 and the water blocking rib 513 to cooperate with each other, the deformation resistance of the lower cover 10 can be further enhanced, and the arrangement of the components inside the cooking apparatus can be prevented from being affected.

In one possible implementation, referring to fig. 5, the water-proof rib 513 is a strip rib plate at the edge of the inner wall of the lower cover 10, which plays a role in preventing the external accumulated water from entering the cooking device, and in this example, by using the height of the water-proof rib 513 itself, the height of the limiting member 523 can be reduced, which is beneficial to preventing the problem that the limiting member 523 is too high to cause breakage.

In one possible implementation, referring to fig. 6, the stop 523, the first baffle 521, and the second baffle 522 are spaced apart from one another about the center of the mounting hole 21. So that the circumference of the mounting hole 21 can be effectively supported, thereby improving the ability of the circumference of the panel 30 to withstand the deformation of the lower cover 10 in a direction approaching the upper cover 20.

In one possible implementation, the limiting member 523, the first baffle plate 521 and the second baffle plate 522 may have an included angle θ between two of 110 ° to 130 ° at the center of the mounting hole 21, for example, the included angle θ between each two is 120 °, so that each second protrusion 52 is stressed uniformly, and the protection effect on the second protrusion 52 is improved. Of course, the included angle θ between each two may be unequal.

In one possible implementation, referring to fig. 6, 9 and 15, the limiting member 523 includes a first rib 5231 and a second rib 5232, where the first rib 5231 and the second rib 5232 are both connected to the inner wall of the upper cover 20, and one ends of the first rib 5231 and the second rib 5232, which are opposite to the inner wall of the upper cover 20, extend to the upper side of the water-blocking rib 513, and the projections of the first rib 5231 and the second rib 5232 on the horizontal plane overlap with the projections of the water-blocking rib 513 on the horizontal plane at least partially. This is to ensure that the water blocking rib 513 and the stopper 523 can abut each other and do not become dislocated when the lower cover 10 is deformed to move in the direction approaching the upper cover 20, and to restrict the movement of the lower cover 10 in the direction approaching the upper cover 20.

In one possible implementation, referring to fig. 5, 6 and 9, the first and second webs 5231 and 5232 are parallel to each other, and the first and second webs 5231 and 5232 are perpendicular to the water barrier 513. By the simultaneous action of the first and second webs 5231, 5232, the stress can be shared, reducing the likelihood of the first and second webs 5231, 5232 breaking or deflecting.

In one possible implementation, the stop 523 further includes a third rib 5233, and the third rib 5233 is connected between the first rib 5231 and the second rib 5232. The third rib plate 5233 can improve the structural strength of the first rib plate 5231 and the second rib plate 5232, and can prevent the first rib plate 5231 and the second rib plate 5232 from being deflected or broken when the water blocking rib 513 abuts against the stopper 523.

In other possible embodiments, the protruding structure may include a second protruding member 52 disposed on the inner wall surface of the upper cover 20, and an end of the second protruding member 52 away from the upper cover 20 extends to have a predetermined distance H from the inner wall surface of the lower cover 10. Therefore, the second protrusion 52 directly abuts against the inner wall surface of the lower cover 10, thereby restricting the movement deformation of the lower cover 10 in the direction approaching the upper cover 20.

Referring to fig. 1 and 4, in the case that the cooking apparatus provided by the embodiment of the present utility model is an induction cooker, a plurality of heat dissipation holes 12 are formed on the periphery of the lower cover 10, so as to dissipate heat of the cooking apparatus, four supporting legs 13 are connected to the bottom of the lower cover 10, and the four supporting legs 13 are respectively connected to four corner positions, so that the placement stability of the cooking apparatus is improved.

The heating plate assembly 40 is a coil plate, and a temperature measuring element is arranged at the center of the coil plate, and the temperature measuring element can be a negative temperature coefficient thermistor (Negative Temperature Coefficient, abbreviated as NTC), and of course, the temperature measuring element can also be a thermocouple or the like, and the temperature measuring element is used for detecting the heating temperature.

When cooking, the coil panel is supplied with alternating current, an alternating magnetic field is generated around, magnetic lines of force of the alternating magnetic field pass through the metal pan bottom, and a large amount of eddy current is generated in the pan bottom, so that heat required for cooking is generated.

The wind shielding rib 512 is used for guiding the airflow in the accommodating cavity 11 to flow to enable more cold air to blow to the heating disc assembly 40, and the present utility model utilizes the existing wind shielding rib 512 structure to realize the effect of limiting the deformation of the lower cover 10 in the direction approaching to the lower cover 10 by the mutual matching of the wind shielding rib 512 and the second baffle 522, so that the cost is low.
