Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of cooking utensils, in particular to a heating utensil. BACKGROUND

[0002] In the field of modern kitchen appliances, electromagnetic stoves are widely used due to their high efficiency and energy saving. Conventional planar electromagnetic stoves, as shown in Figure 21 and Figure 22 , cannot heat the pot wall itself when a wok is used because the coil disc magnetic lines cannot penetrate the wok wall, resulting in low pot wall temperature and poor cooking effect. Therefore, as shown in Figure 23 and Figure 24 , related technologies propose an arc-shaped electromagnetic stove, whose panel 2' and coil disc 3' are arc-shaped and match the wok wall 1', which can improve the cooking effect. However, both planar electromagnetic stoves and arc-shaped electromagnetic stoves have the problem of pot compatibility. The former cannot use arc-bottom pots, and the latter cannot use flat-bottom pots. Based on the above heating and pot compatibility problems, some electromagnetic stoves with multi-panel structures have gradually appeared on the market. Such multi-panel structures aim to achieve diversified functional layout or aesthetic design. For example, related technologies propose an electromagnetic stove with a lifting panel that can adapt to pots with different shapes, but this brings a serious safety hazard. In daily use, if the sealing between the multi-panels is not good, or the multi-panels move relatively due to external factors, water is easy to enter the electromagnetic stove from the gap between the multi-panels, which may cause short circuit of the key components such as electronic components, circuit lines, and electromagnetic induction coils inside the electromagnetic stove.

[0003] Therefore, how to design a heating utensil that prevents liquid from contacting the live parts inside the electromagnetic stove when liquid flows into the electromagnetic stove has become a problem to be solved. SUMMARY

[0004] The utility model aims to at least solve the problem that liquid entering the electromagnetic stove easily contacts live parts and causes short circuit.

[0005] To this end, the first aspect of the utility model provides a heating utensil.

[0006] Therefore, the first aspect of the utility model provides a heating utensil.

[0007] The heating appliance provided by the utility model, which comprises a shell, a panel assembly, a first heating piece, a second heating piece and a water collecting groove. The panel assembly is arranged at the opening of the shell, and the cooking appliance can be placed on the panel assembly, so that the cooking appliance on the panel assembly can be heated by the first heating piece and the second heating piece. Meanwhile, the arrangement of the first panel and the second panel can meet diversified cooking requirements, for example, different sizes or types of cooking appliances can be heated adaptively, and the functional flexibility and practicality of the heating appliance are effectively improved. The first heating piece and the second heating piece are respectively arranged below the corresponding panels, can accurately and efficiently heat the cooking appliance placed on different panels, make heat transfer more concentrated and uniform, thereby shortening the cooking time and improving the cooking effect. The water collecting groove is arranged in the shell and is correspondingly arranged at the joint of the first panel and the second panel, so that the water collecting groove can receive the liquid entering the interior of the shell from the joint of the first panel and the second panel, the risk of internal circuit short circuit caused by liquid leakage is avoided, the safe and stable operation of the heating appliance is ensured, and the inconvenience and cost increase caused by fault maintenance are reduced.

[0008] According to the heating appliance provided by the utility model, the following additional technical features can also be provided:

[0009] In some embodiments, one of the first panel and the second panel can be moved relative to the other.

[0010] In these embodiments, the first panel and the second panel can be arranged to be moved relative to each other, so that the heating appliance can adapt to different shapes of pots, and the adaptability of the heating appliance is improved. When facing different sizes and shapes of cooking appliances, the user can conveniently adjust the relative position relationship of the first panel and the second panel, thereby providing a more accurate and stable placement support surface for the cooking appliance. For example, for a large size flat-bottomed pot, the effective heating area can be expanded by moving the panel. For special-shaped cooking appliances, better fitting placement can be achieved by flexibly adjusting the panel position, effectively avoiding the situation that the cooking appliance is unstable or partially suspended and cannot be effectively heated due to the fixed panel, and the uniformity and efficiency of heating are significantly improved.

[0011] In some embodiments, the heating appliance further comprises a first waterproof rib arranged on the bottom wall of the shell and surrounding the water collecting groove with the bottom wall of the shell.

[0012] In these embodiments, the water collecting groove can be surrounded by the first waterproof rib, and specifically, the first waterproof rib can be arranged on the bottom wall of the shell to surround the water collecting groove with the bottom wall of the shell. The way of constructing the water collecting groove by the first waterproof rib is relatively simple and easy to manufacture, and will not excessively increase the production process complexity and cost of the heating appliance.

[0013] In some embodiments, optionally, the first panel is arranged at the opening, the first panel has a through hole, the second panel is arranged at the through hole, and the first heating element is arranged around the outer periphery of the second heating element.

[0014] In some embodiments, the first panel is arranged at the opening, the second panel is arranged at the through hole of the first panel, and the first heating element is arranged around the outer periphery of the second heating element. Such an arrangement can provide omnidirectional and multi-level heating of the cooking utensil from different directions. For small or special-shaped cooking utensils placed on the second panel, the cooking utensils can not only receive direct heat from the second heating element from the bottom, but also receive side heat from the first heating element around the outer periphery, greatly improving the uniformity and efficiency of heating and precisely meeting special cooking needs. For example, when the second panel is recessed into the housing, the first heating element can compensate for the heating of the side of the cooking utensil placed on the second panel, thereby improving the uniformity of heating.

[0015] In some embodiments, optionally, the heating appliance further comprises a heat dissipation fan arranged in the housing and configured to dissipate heat from the first heating element and the second heating element.

[0016] In some embodiments, the heat dissipation fan can be arranged in the housing to dissipate heat from the first heating element and the second heating element, thereby prolonging the service life of the heating elements, ensuring the safety of the heating appliance, and improving the user experience.

[0017] In some embodiments, optionally, the area of the water receiving groove is greater than the area of the second panel, and the heat dissipation fan comprises a first heat dissipation fan arranged at the bottom wall of the housing, and the side wall of the water receiving groove is provided with an air inlet, and the first heat dissipation fan is arranged at the air inlet.

[0018] In some embodiments, the area of the water receiving groove is greater than the area of the second panel, so that the projection of the second panel in the height direction falls within the water receiving groove, thereby ensuring that the liquid entering from the joint between the first panel and the second panel falls into the water receiving groove. At the same time, the first heat dissipation fan can be arranged at the bottom wall of the housing, the air inlet can be arranged at the side wall of the water receiving groove, and the first heat dissipation fan can be arranged at the air inlet. In this way, the air generated by the heat dissipation fan can be blown into the water receiving groove through the air inlet, and due to the blockage of the side wall of the water receiving groove, the airflow will flow towards the opening of the water receiving groove, i.e., the airflow will flow towards the second panel, thereby dissipating heat from the second heating element on the second panel. At the same time, due to the blockage of the second heating element, the airflow will spread around the surface of the second heating element, thereby flowing to the first heating element, thereby dissipating heat from the first heating element.

[0019] In some embodiments, the heating device further comprises: a turbulence fin arranged in the water receiving groove and located between the bottom wall of the shell and the second heating element, for guiding the air blown by the first air cooling fan to the second heating element.

[0020] In some embodiments, in order to further improve the heat dissipation effect, a turbulence fin can be arranged in the water receiving groove and located between the bottom wall of the shell and the second heating element. It can be understood that, since the area of the water receiving groove is large, the air flow entering the water receiving groove is extremely weak when it touches the side wall of the water receiving groove, so that the air flow is difficult to effectively blow to the second heating element when the side wall of the water receiving groove guides the air flow. The arrangement of the turbulence fin effectively solves this problem, which can reduce the flow path of the air flow in the water receiving groove and enhance the impact force of the air flow, so that the air flow can flow more easily to the second heating element, thereby significantly improving the heat dissipation effect, ensuring that all components of the heating device are in good thermal balance during operation, prolonging the service life of the device and ensuring its stable operation.

[0021] In some embodiments, the turbulence fin surrounds an installation groove in the water receiving groove, and the bottom wall of the installation groove is provided with an air inlet hole, and the heat dissipation fan further comprises: a second air cooling fan arranged in the installation groove for cooling the second heating element.

[0022] In some embodiments, the turbulence fin surrounds an installation groove in the water receiving groove, so that a second air cooling fan can be arranged in the installation groove to further cool the second heating element and improve the heat dissipation effect. It can be understood that, since the turbulence fin surrounds the installation groove in the water receiving groove, the installation groove cannot receive the liquid flowing into the interior of the shell, and the liquid flowing into the interior of the shell is received through the space outside the installation groove in the water receiving groove. Since the second air cooling fan is arranged in the installation groove, an air inlet hole can be further arranged on the bottom wall of the installation groove to communicate with the outside, thereby ensuring the normal operation of the second air cooling fan.

[0023] In some embodiments, the second panel is movable between a first position and a second position, and when the second panel is in the first position, the second panel is flush with the first panel, and when the second panel is in the second position, the second panel is located in the shell.

[0024] In some embodiments, the second panel can be configured to be movable, and when the second panel is in the first position, i.e. flush with the first panel, the heating appliance presents a complete and continuous cooking surface, which is extremely advantageous for placing large cooking utensils, such as large frying pans or baking trays, to provide sufficient and stable support area, and to ensure that the utensils will not shake or tilt during cooking due to the unevenness at the joint between the panels, thereby ensuring the uniformity and safety of cooking. When the second panel is moved to the second position, i.e. inside the housing, the heating appliance can flexibly adapt to different cooking utensils. For example, when using a cooking utensil with an arc-shaped bottom, the second panel can be adjusted to the second position so that the bottom of the arc-shaped bottom is in contact with the second panel, and then the first panel is used to limit the cooking utensil to improve the stability of the cooking utensil. At the same time, the first heating element on the first panel can be used to heat the sidewall of the arc-shaped bottom to improve the heating effect.

[0025] In some embodiments, optionally, when the second panel is in the first position, the distance between the turbulence rib and the second heating element is less than or equal to 50 mm; and when the second panel is in the second position, the distance between the turbulence rib and the second heating element is greater than or equal to 2 mm.

[0026] In some embodiments, when the second panel is in the first position, the distance between the turbulence rib and the second heating element is less than or equal to 50 mm; and when the second panel is in the second position, the distance between the turbulence rib and the second heating element is greater than or equal to 2 mm. By limiting the distance between the turbulence rib and the second heating element, this arrangement can prevent the problem of poor air flow and poor heat dissipation caused by too large or too small distance.

[0027] In some embodiments, optionally, the heating appliance further comprises at least one air outlet arranged on the sidewall of the water collecting groove and away from the bottom wall of the water collecting groove.

[0028] In some embodiments, at least one air outlet can be arranged on the sidewall of the water collecting groove, and the air outlet is arranged away from the bottom wall of the water collecting groove, which can make the heat dissipation air flow more smoothly and reduce the obstruction of the water collecting groove to the heat dissipation air flow, thereby improving the heat dissipation effect. More specifically, if the first heating element is arranged around the second heating element, arranging at least one air outlet can make the heat dissipation air flow more easily to the first heating element.

[0029] In some embodiments, optionally, the air outlet is a plurality of air outlets, and the plurality of air outlets are arranged at intervals along the circumferential direction of the water collecting groove.

[0030] In some embodiments, to further improve the heat dissipation effect, the air outlet can be arranged as a plurality of air outlets, and the plurality of air outlets are arranged at intervals along the circumferential direction of the water collecting groove.

[0031] In some embodiments, the heating appliance further comprises a second waterproof rib arranged on the bottom wall of the housing and surrounding the water receiving groove, and the second waterproof rib and the side wall of the water receiving groove form an overflow groove.

[0032] In some embodiments, since the water in the water receiving groove can flow out of the water receiving groove, in order to further ensure the stability of the heating appliance, a second waterproof rib can be arranged on the outer periphery of the water receiving groove, so that the second waterproof rib and the side wall of the water receiving groove form an overflow groove, and then the liquid overflowing from the water receiving groove is received by the overflow groove.

[0033] In some embodiments, the height of the second waterproof rib is less than the height of the water receiving groove.

[0034] In some embodiments, in order not to affect the flowability of the cooling air, the height of the second waterproof rib can be set to be less than the height of the water receiving groove.

[0035] In some embodiments, the side wall of the water receiving groove is provided with at least one air outlet, the air outlet is away from the bottom wall of the housing, and the height of the second waterproof rib is less than the height of the air outlet.

[0036] In some embodiments, when the side wall of the water receiving groove is provided with at least one air outlet, the height of the second waterproof rib can be set to be less than the height of the air outlet, so as to prevent the second waterproof rib from blocking the cooling air discharged from the air outlet, and ensure the cooling effect.

[0037] In some embodiments, the heating appliance further comprises a circuit board arranged in the housing and located outside the water receiving groove.

[0038] In some embodiments, the circuit board can be arranged in the housing, and various electronic components of the heating appliance are connected and controlled by the circuit board. Since the circuit board is arranged outside the water receiving groove, the liquid flowing into the interior of the housing can be prevented from contacting the circuit board, thereby ensuring the safety and stability of the heating appliance.

[0039] In some embodiments, the heating appliance further comprises at least one drain hole penetrating through the water receiving groove for draining the liquid in the water receiving groove.

[0040] In some embodiments, at least one drain hole can be arranged and penetrate through the water receiving groove, so that the liquid in the water receiving groove can be drained through the drain hole, preventing the liquid in the water receiving groove from overflowing when the liquid is too much, and further ensuring that the liquid does not contact other electronic components in the heating appliance.

[0041] In some embodiments, the drain hole is a plurality of drain holes, and the plurality of drain holes are arranged at intervals along the circumferential direction of the water receiving groove.

[0042] In the embodiments, the drain holes can be arranged in multiple numbers and arranged at intervals along the circumferential direction of the water receiving groove. This arrangement not only improves the drainage efficiency, but also avoids the problem of local water accumulation in the water receiving groove due to the concentration of the drainage position, ensuring that the liquid in each area of the water receiving groove can be smoothly drained. Furthermore, the multiple drain holes arranged along the circumference to some extent enhance the reliability of the entire drainage system. Even if individual drain holes are blocked by impurities or other reasons, other drain holes can still work normally to maintain the basic drainage function of the water receiving groove, so that the entire drainage system does not completely fail, thereby ensuring the stability and safety of the heating appliance during long-term use.

[0043] In some embodiments, the heating appliance further comprises a waterproof assembly arranged at the joint of the first panel and the second panel, for preventing liquid from entering the housing from the joint of the first panel and the second panel.

[0044] In the embodiments, a waterproof assembly can also be arranged at the joint of the first panel and the second panel, thereby cutting off the path of liquid intrusion from the panel joint gap into the housing. This arrangement further reduces the possibility of internal circuit short circuit caused by liquid leakage, and effectively ensures the safe and stable operation of the key components such as internal electronic elements, electrical circuits and electromagnetic induction devices of the heating appliance.

[0045] In some embodiments, the heating appliance comprises at least one of an electromagnetic stove, an electromagnetic induction cooker and an integrated stove.

[0076] In order to more clearly understand the above purpose, features and advantages of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0077] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0078] The following description will be made with reference toFigures 1 to 20 A heating appliance according to some embodiments of the present application is described.

[0079] According to one embodiment of the first aspect of the present application, as shown in Figures 1 to 20 The first aspect of the present application proposes a heating appliance 1, comprising a housing 10, a panel assembly 11, a first heating element 13, a second heating element 14 and a water receiving groove 104. The housing 10 has an opening 102. The panel assembly 11 is arranged at the opening 102 for placing a cooking appliance 2, and the panel assembly 11 comprises a first panel 112 and a second panel 114. The first heating element 13 is arranged on the first panel 112 and located inside the housing 10. The second heating element 14 is arranged on the second panel 114 and located inside the housing 10. The water receiving groove 104 is arranged inside the housing 10 and corresponds to the intersection of the first panel 112 and the second panel 114.

[0080] The heating appliance 1 provided by the present application comprises a housing 10, a panel assembly 11, a first heating element 13, a second heating element 14 and a water receiving groove 104. The panel assembly 11 is arranged at the opening 102 of the housing 10, and the cooking appliance 2 can be placed on the panel assembly 11, so that the cooking appliance 2 on the panel assembly 11 can be heated by the first heating element 13 and the second heating element 14. At the same time, the arrangement of the first panel 112 and the second panel 114 can meet the diversified cooking needs, for example, different sizes or types of cooking appliances 2 can be adaptively heated, effectively improving the functional flexibility and practicality of the heating appliance 1. The first heating element 13 and the second heating element 14 are respectively located below the corresponding panels, which can accurately and efficiently heat the cooking appliance 2 placed on different panels, making the heat transfer more concentrated and uniform, thereby shortening the cooking time and improving the cooking effect. The water receiving groove 104 is arranged inside the housing 10 and corresponds to the intersection of the first panel 112 and the second panel 114, so that the water receiving groove 104 can receive the liquid entering the inside of the housing 10 from the intersection of the first panel 112 and the second panel 114, avoiding the risk of internal circuit short circuit caused by liquid leakage, ensuring the safe and stable operation of the heating appliance 1, and reducing the inconvenience and cost increase caused by fault maintenance.

[0081] In some embodiments, as shown in Figure 6 and Figure 8 One of the first panel 112 and the second panel 114 can move relative to the other.

[0082] In some embodiments, the first panel 112 and the second panel 114 can be arranged to be movable relative to each other, so that the heating appliance 1 can be adapted to different shapes of the cooking utensil 2, improving the adaptability of the heating appliance 1. When facing different sizes and shapes of the cooking utensil 2, the user can conveniently adjust the relative position relationship between the first panel 112 and the second panel 114, so as to provide a more accurate and stable placement support surface for the cooking utensil 2. For example, for a large size pan, the effective heating area can be expanded by moving the panel. For special-shaped cooking utensils 2, better fitting placement can be achieved by flexibly adjusting the panel position, effectively avoiding the situation that the cooking utensil 2 is placed unstably or partially suspended and cannot be effectively heated due to the fixed panel, significantly improving the uniformity and efficiency of heating.

[0083] In some embodiments, as shown in Figure 2 、 Figure 3 and Figure 10 , the heating appliance 1 further comprises a first waterproof rib 1042 arranged on the bottom wall of the shell 10 to form a water receiving groove 104 with the bottom wall of the shell 10.

[0084] In some embodiments, the water receiving groove 104 can be arranged to be surrounded by the first waterproof rib 1042, specifically, the first waterproof rib 1042 can be arranged on the bottom wall of the shell 10 to form the water receiving groove 104 with the bottom wall of the shell 10. The way of constructing the water receiving groove 104 by the first waterproof rib 1042 is relatively simple and easy to manufacture, without excessively increasing the production process complexity and cost of the heating appliance 1.

[0085] In some embodiments, the first panel 112 is arranged at the opening 102, the first panel 112 has a through hole 1122, the second panel 114 is arranged at the through hole 1122, and the first heating member 13 is arranged around the outer periphery of the second heating member 14.

[0086] In some embodiments, the first panel 112 can be arranged at the opening 102, the second panel 114 can be arranged at the through hole 1122 of the first panel 112, and the first heating member 13 can be arranged around the outer periphery of the second heating member 14. This arrangement can provide omnidirectional and all-around heating of the cooking utensil 2 from different directions and levels. For small or special-shaped cooking utensils 2 placed on the second panel 114, they can not only obtain direct heat from the second heating member 14 from the bottom, but also receive side heat from the first heating member 13 around the periphery, greatly improving the uniformity and efficiency of heating, and accurately meeting special cooking needs. For example, when the second panel 114 is recessed into the shell 10, the first heating member 13 can compensate for the heating of the side of the cooking utensil 2 placed on the second panel 114, thereby improving the uniformity of heating.

[0087] In some embodiments, the heating appliance 1 may optionally include a heat dissipation fan 15 disposed within the housing 10 for dissipating heat from the first heating element 13 and the second heating element 14.

[0088] In these embodiments, a cooling fan 15 can also be provided inside the housing 10 to dissipate heat from the first heating element 13 and the second heating element 14, thereby extending the service life of the heating elements, ensuring the safety of the heating appliance 1, and improving the user experience.

[0089] In some embodiments, optionally, such as Figure 1 As shown, the area of ​​the water tank 104 is larger than the area of ​​the second panel 114. The cooling fan 15 includes: a first cooling fan 152, which is disposed on the bottom wall of the housing 10. An air inlet 1044 is opened on the side wall of the water tank 104, and the first cooling fan 152 is disposed at the air inlet 1044.

[0090] In these embodiments, the area of ​​the water receiving tank 104 is larger than the area of ​​the second panel 114, so that the projection of the second panel 114 in the height direction falls within the water receiving tank 104, thereby ensuring that liquid entering from the junction of the first panel 112 and the second panel 114 can fall into the water receiving tank 104. Simultaneously, a first cooling fan 152 can be provided on the bottom wall of the housing 10, and an air inlet 1044 can be provided on the side wall of the water receiving tank 104. The first cooling fan 152 is then positioned at the air inlet 1044, allowing the air generated by the cooling fan 152 to be blown into the water receiving tank 104 through the air inlet 1044. Due to the obstruction of the side wall of the water receiving tank 104, the airflow will flow towards the opening 102 of the water receiving tank 104, that is, towards the second panel 114. This allows the airflow to dissipate heat from the second heating element 14 on the second panel 114. At the same time, due to the obstruction of the second heating element 14, the airflow will spread and flow in all directions along the surface of the second heating element 14, thus flowing to the first heating element 13, thereby achieving heat dissipation of the first heating element 13.

[0091] In some embodiments, optionally, such as Figure 5 As shown, the heating appliance 1 also includes: a baffle 106, which is disposed in the water receiving tank 104 and located between the bottom wall of the housing 10 and the second heating element 14, for guiding the air blown out by the first cooling fan 152 to the second heating element 14.

[0092] In the embodiments, in order to further improve the heat dissipation effect, the turbulence ribs 106 can also be arranged in the water receiving groove 104 and located between the bottom wall of the shell 10 and the second heating element 14. It can be understood that, since the area of the water receiving groove 104 is large, the airflow entering the water receiving groove 104 is extremely weak when it touches the side wall of the water receiving groove 104, so that the airflow is difficult to effectively blow to the second heating element 14 when the airflow is guided by the side wall of the water receiving groove 104. The arrangement of the turbulence ribs 106 effectively solves this problem, which can reduce the flow path of the airflow in the water receiving groove 104 and enhance the impact force of the airflow, so that the airflow can more easily flow to the second heating element 14, thereby significantly improving the heat dissipation effect, ensuring that the components of the heating appliance 1 are always in a good heat balance state during operation, prolonging the service life of the equipment and ensuring stable operation.

[0093] In some embodiments, as shown in Figure 11 and Figure 12 , the turbulence ribs 106 enclose an installation groove 1062 in the water receiving groove 104, the bottom wall of the installation groove 1062 is provided with an air inlet hole 1064, and the heat dissipation fan 15 further comprises: a second heat dissipation fan 154 arranged in the installation groove 1062 and used for dissipating heat of the second heating element 14.

[0094] In the embodiments, the turbulence ribs 106 enclose the installation groove 1062 in the water receiving groove 104, so that the second heat dissipation fan 154 can be arranged in the installation groove 1062 to further dissipate heat of the second heating element 14, thereby improving the heat dissipation effect. It can be understood that, since the turbulence ribs 106 enclose the installation groove 1062 in the water receiving groove 104, the installation groove 1062 cannot receive the liquid flowing into the interior of the shell 10, and the liquid flowing into the interior of the shell 10 is received through the space outside the installation groove 1062 in the water receiving groove 104. Since the second heat dissipation fan 154 is arranged in the installation groove 1062, the air inlet hole 1064 can be arranged on the bottom wall of the installation groove 1062 to communicate with the outside, thereby ensuring the normal work of the second heat dissipation fan 154.

[0095] In some embodiments, the installation groove 1062 is located in the middle of the water receiving groove 104.

[0096] In some embodiments, the second panel 114 is movable between a first position and a second position, the second panel 114 is flush with the first panel 112 when the second panel 114 is in the first position, and the second panel 114 is located in the shell 10 when the second panel 114 is in the second position.

[0097] In the embodiments, the second panel 114 can be arranged as a movable structure, and when the second panel 114 is in the first position, as shown in Figure 13、 Figure 17 and Figure 18 As shown in Figure 14 、 Figure 15 、 Figure 16 、 Figure 19 and Figure 20 , when the second panel 114 is located in the first position, the heating appliance 1 presents a complete and continuous cooking surface, which is extremely advantageous for placing large cooking utensils 2, such as large pans or baking trays, to provide sufficient and stable support area, ensuring that the utensils will not shake or tilt due to the unevenness of the panel joint during cooking, thereby ensuring the uniformity and safety of cooking. When the second panel 114 is moved to the second position, as shown in

[0098] In some embodiments, as shown in Figure 7 and Figure 9 , the distance H2 between the second panel 114 in the first position and the second heating element 14 is less than or equal to 50 mm; and the distance H1 between the second panel 114 in the second position and the second heating element 14 is greater than or equal to 2 mm.

[0099] In these embodiments, the distance between the second panel 114 in the first position and the second heating element 14 is less than or equal to 50 mm. The distance between the second panel 114 in the second position and the second heating element 14 is greater than or equal to 2 mm. This arrangement, by limiting the distance between the second panel 114 and the second heating element 14, can prevent the problem of poor air flow and poor heat dissipation caused by too large or too small distance.

[0100] In some embodiments, the heating appliance 1 further comprises at least one air outlet 1046 arranged on the side wall of the water receiving groove 104 and away from the bottom wall of the water receiving groove 104.

[0101] In some embodiments, at least one air outlet 1046 can be arranged on the sidewall of the water receiving groove 104, and the air outlet 1046 is arranged away from the bottom wall of the water receiving groove 104. In this way, the flow of the cooling air can be smoother, and the water receiving groove 104 can reduce the obstruction to the flow of the cooling air, thereby improving the cooling effect. More specifically, if the first heating element 13 is arranged around the second heating element 14, the arrangement of the at least one air outlet 1046 can make the cooling air flow more easily to the first heating element 13.

[0102] In some embodiments, the air outlet 1046 can be multiple, and the multiple air outlets 1046 can be arranged at intervals along the circumferential direction of the water receiving groove 104.

[0103] In some embodiments, in order to further improve the cooling effect, the air outlet 1046 can be multiple, and the multiple air outlets 1046 can be arranged at intervals along the circumferential direction of the water receiving groove 104 (the direction indicated by Z). Figure 10

[0104] In some embodiments, the multiple air outlets 1046 can be arranged uniformly along the circumferential direction of the water receiving groove 104.

[0105] In some embodiments, the heating appliance 1 can further comprise a second waterproof rib 108 arranged on the bottom wall of the housing 10 and arranged around the water receiving groove 104. The second waterproof rib 108 can surround the sidewall of the water receiving groove 104 to form an overflow groove 1082.

[0106] In some embodiments, since the water in the water receiving groove 104 can flow out of the water receiving groove 104, in order to further ensure the stability of the heating appliance 1, a second waterproof rib 108 can be arranged on the outer periphery of the water receiving groove 104, so that the second waterproof rib 108 surrounds the sidewall of the water receiving groove 104 to form an overflow groove 1082, thereby receiving the liquid overflowing from the water receiving groove 104 through the overflow groove 1082.

[0107] In some embodiments, the height of the second waterproof rib 108 can be less than the height of the water receiving groove 104.

[0108] In some embodiments, in order not to affect the flowability of the cooling air, the height of the second waterproof rib 108 can be less than the height of the water receiving groove 104.

[0109] In some embodiments, the sidewall of the water receiving groove 104 can be provided with at least one air outlet 1046, the air outlet 1046 is arranged away from the bottom wall of the housing 10, and the height of the second waterproof rib 108 is less than the height of the air outlet 1046.

[0110] ​In the embodiments, when the side wall of the water receiving groove 104 is provided with at least one air outlet 1046, the height of the second waterproof rib 108 can be set to be less than the height of the air outlet 1046, so as to prevent the second waterproof rib 108 from blocking the heat dissipation air discharged from the air outlet 1046, and ensure the heat dissipation effect.

[0111] In some embodiments, the heating appliance 1 further comprises a circuit board 16 arranged in the housing 10 and located outside the water receiving groove 104.

[0112] In the embodiments, the circuit board 16 can be arranged in the housing 10, and various electronic components of the heating appliance 1 can be connected and controlled through the circuit board 16. Since the circuit board 16 is arranged outside the water receiving groove 104, the liquid flowing into the inside of the housing 10 can be prevented from contacting the circuit board 16, thereby ensuring the safety and stability of the heating appliance 1.

[0113] In some embodiments, the heating appliance 1 further comprises at least one drain hole 17 penetrating through the water receiving groove 104, for draining the liquid in the water receiving groove 104. Figure 4

[0114] In the embodiments, the at least one drain hole 17 can be arranged and penetrate through the water receiving groove 104, so that the liquid in the water receiving groove 104 can be drained through the drain hole 17, and the overflow of the liquid in the water receiving groove 104 can be prevented when the liquid in the water receiving groove 104 is too much, thereby further ensuring that the liquid does not contact other electronic components in the heating appliance 1.

[0115] In some embodiments, the drain hole 17 is in communication with the outside, so that the liquid can be directly drained out of the heating appliance 1.

[0116] In some embodiments, the heating appliance 1 further comprises a water stop plug which is detachably arranged at the drain hole 17 and used for sealing the drain hole 17.

[0117] ​In some embodiments, the water outlet hole 17 is sealed by the water stop plug, which can prevent the liquid in the water collecting groove 104 from continuously flowing out. In a daily cooking situation, without the effective control of the water stop plug, the liquid in the water collecting groove 104 may continuously flow out and drip on the kitchen countertop or floor, causing the countertop to be wet and easy to breed bacteria, the floor to be slippery and increase the safety hazard, and greatly affect the cleanliness of the kitchen environment and the user's comfort. In specific use, when the liquid in the water collecting groove 104 gradually accumulates to a preset amount, the water stop plug can be opened for centralized drainage operation. This way can ensure that the accumulated liquid is completely drained at one time, effectively preventing the problems such as odor or mildew caused by the residual liquid in the water collecting groove 104. After completing the drainage, the water stop plug is reinstalled back to the water outlet hole 17, so as to restore the sealing state of the water collecting groove 104, so that it can continue to normally collect the liquid flowing from the panel gap, thereby providing reliable protection for the stable operation of the heating appliance 1 and the good maintenance of the kitchen environment.

[0118] In some embodiments, optionally, the water outlet hole 17 is a plurality of water outlet holes 17, and the plurality of water outlet holes 17 are arranged along the circumferential direction of the water collecting groove 104.

[0119] In some embodiments, the water outlet hole 17 can be arranged as a plurality of water outlet holes 17, and the plurality of water outlet holes 17 are arranged along the circumferential direction of the water collecting groove 104. This arrangement not only improves the drainage efficiency, but also avoids the problem of local water accumulation in the water collecting groove 104 caused by the concentration of the drainage position, ensuring that the liquid in each area of the water collecting groove 104 can be smoothly drained. Furthermore, the plurality of water outlet holes 17 arranged along the circumference to some extent enhances the reliability of the entire drainage system. Even if individual water outlet holes 17 are blocked by impurities or other reasons, other water outlet holes 17 can still work normally to maintain the basic drainage function of the water collecting groove 104, so that the entire drainage system will not be completely paralyzed, thereby ensuring the stability and safety of the heating appliance 1 during long-term use.

[0120] In some embodiments, optionally, the heating appliance 1 further comprises a waterproof assembly 18 arranged at the joint of the first panel 112 and the second panel 114, for preventing the liquid from entering the housing 10 from the joint of the first panel 112 and the second panel 114.

[0121] In some embodiments, the waterproof assembly 18 can also be arranged at the joint of the first panel 112 and the second panel 114, thereby cutting off the path of the liquid invading the housing 10 from the panel joint gap. This arrangement further reduces the possibility of internal circuit short circuit caused by liquid leakage, and effectively ensures the safe and stable operation of the key components such as internal electronic elements, electrical circuits and electromagnetic induction devices of the heating appliance 1.

[0122] In some embodiments, the heating appliance 1 optionally comprises at least one of an electromagnetic hob, an induction hob, and an integrated hob.

[0123] In some embodiments, the heating appliance 1 is a heating appliance with a double panel assembly, so that two same or different cooking utensils 2 can be heated at the same time.

[0124] As shown in Figure 7 and Figure 9 , the direction of the arrow in the figure is the flow trajectory of the cooling air. Due to the presence of the spoiler rib 106, the cooling air flows upwards to the coil disc (second heating element 14) and then to the compensating coil disc (first heating element 13), thereby cooling the coil disc and the compensating coil disc.

[0125] At the same time, in order to make the flow of cooling air smoother, an air outlet fence (air outlet 1046) can be provided on the first waterproof rib 1042. However, at the same time, due to the provision of the air outlet fence, part of the incoming liquid may flow to the periphery of the first waterproof rib 1042. Therefore, a second waterproof rib 108 needs to be provided on the periphery of the first waterproof rib 1042, and a drain hole 17 is provided inside the first waterproof rib 1042, so that the water entering the first waterproof rib 1042 and the second waterproof rib 108 can flow out of the shell 10. It should be noted that the height of the second waterproof rib 108 is lower than the height of the first waterproof rib 1042. A more optimal design is that the height of the air outlet fence of the first waterproof rib 1042 is lower. In this way, the second waterproof rib 108 will not block the flow of cooling air.

[0126] Further, if the above scheme is not sufficient for cooling, a second cooling fan 154 can be added below the coil disc (second heating element 14), which sucks in cold air from the bottom of the shell 10 to cool the coil disc.

[0127] Due to the use of different pots, the elastic panel (second panel) has two states of sinking and not sinking. When in the state of not sinking, the gap H2 between the spoiler rib and the coil disc is larger than H1 in the state of sinking, causing part of the cooling air to directly flow through without cooling the coil disc. Therefore, a more optimal design is H1≥2mm and H2≤50mm. In this way, it can be ensured that the airflow is not too large or too small to affect the cooling effect.

[0128] The key point of the present application is:

[0129] 1. Single fan cooling result.

[0130] 2. Design of spoiler rib, first waterproof rib air outlet fence, and height relationship between second waterproof rib and first waterproof rib.

[0131] 3. Cooling scheme of adding a second cooling fan.

[0132] 4. The suggested values of the gap between the spoiler and the coil plate. H1≥2mm, H2≤50mm.
