The high temperature of the surface of the electric ceramic furnace can reach about 600 ℃, and the existing electric ceramic furnace does not have special protection when being in an idle state without being watched by people and still continues to work according to the previous set mode of the electric ceramic furnace.

However, when the electric ceramic furnace is unattended and in an idle state, not only can electric power be wasted, and the service life of the electric ceramic furnace is easily reduced for a long time, but also the heat of the electric ceramic furnace is not absorbed by a pot, and because the high-temperature radiation baking of the electric ceramic furnace can damage surrounding objects and even possibly cause safety accidents, the electric ceramic furnace has certain potential safety hazards in the idle state.

In view of this, the utility model provides a cooking utensil not only can realize the detection of the object on the cooking utensil such as pan or overware etc. makes cooking utensil have safe energy-conserving characteristics moreover.

The utility model arranges the detection component in the cavity, because the end part of the trigger unit in the detection component extends out and is exposed on the panel, and the trigger unit is movably arranged relative to the induction unit, so that when a cooker or a baking tray and the like are placed on the panel of the cooking utensil, the end part of the trigger unit is pressed, the triggering unit moves relative to the sensing unit to trigger the sensing unit, correspondingly, the sensing unit can also generate signal change, the electric control component can realize the detection of objects on the cooking utensil, such as a cooker or a baking tray and the like according to the signal change on the sensing unit, the cooking appliance is controlled to be closed or opened through the electric control assembly, so that when the cooking appliance is in an idle state (namely, no object such as a cooker or a baking tray is placed on the cooking appliance), the cooking appliance is controlled to be closed, and the cooking appliance has the characteristics of safety and energy saving.

The cooking appliance can be an electric ceramic oven, an induction cooker or other cooking appliances with a panel and an electric control assembly.

The cooking utensil in the present embodiment is further described below by taking an electric ceramic oven as an example.

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example one

Fig. 1 is a schematic structural view of an electric ceramic stove according to an embodiment of the present invention, fig. 2 is a schematic structural view of an internal structure of an electric ceramic stove according to an embodiment of the present invention, fig. 3 is a cross-sectional view of an electric ceramic stove a-a direction in fig. 1 according to an embodiment of the present invention, and fig. 4 is an enlarged view of an electric ceramic stove B portion in fig. 3 according to an embodiment of the present invention.

Referring to fig. 1 to 4, the present invention provides a structural schematic diagram of an electric ceramic stove. As can be seen from fig. 1 to 4, a cooking appliance such as an electric ceramic oven 100 may include a housing 10, a panel 20, an electric control assembly 40 and a detection assembly, wherein the panel 20 is covered on the housing 10 and forms a cavity 13 with the housing 10, and the electric control assembly 40 and the detection assembly are both disposed in the cavity 13. The detection assembly comprises a trigger unit 50 and a sensing unit 60, wherein the sensing unit 60 is arranged opposite to the trigger unit 50 and is electrically connected with the electronic control assembly 40. The end of the triggering unit 50 is extended and exposed above the panel 20, and the triggering unit 50 is movably disposed relative to the sensing unit 60 to trigger the sensing unit 60.

Thus, when a pot, a baking tray or other objects with a certain weight are placed on the cooking utensil such as the cooking utensil on the panel 20 of the electric ceramic oven 100, the end of the triggering unit 50 is pressed, and under the pressing of the objects, the triggering unit 50 moves towards the cavity 13 and moves relative to the sensing unit 60, and at this time, the position of the triggering unit 50 relative to the sensing unit 60 changes to trigger the sensing unit 60. Correspondingly, because the position of the trigger unit 50 relative to the sensing unit 60 changes, the sensing unit 60 also generates a signal change, and the electronic control component 40 can detect an object on the cooking appliance, such as a pot or a baking tray, according to the signal change on the sensing unit 60, so as to control the heating power of the cooking appliance to be turned off or turned on through the electronic control component 40, so that when the cooking appliance, such as the electric ceramic oven 100, is in an idle state (i.e., no object, such as a pot or a baking tray, is placed on the electric ceramic oven 100), the cooking appliance can be controlled to be turned off, so as to prevent the cooking appliance from being continuously heated in the idle state, so that the cooking appliance has the characteristics of safety and energy saving, which is beneficial to improving the safety coefficient of the cooking appliance and prolonging the service life of the cooking appliance. Accordingly, when it is detected that the cooking appliance such as the electric ceramic oven 100 is in the pot state (i.e. the cooking appliance has a pot placed thereon), the electric control assembly 40 can also control the cooking appliance to be turned on for heating.

Besides, because the trigger unit 50 can move relative to the induction unit 60, when the detection of the object on the cooking appliance, such as a pot or a baking tray, is realized, on one hand, the normal use of the cooking appliance, the pot or the baking tray and the like is not influenced, and on the other hand, the influence on the bottom of the pot or the baking tray and the like is avoided, on the other hand, the detection component is a non-contact trigger structure, mechanical transmission is not needed, the complexity of the structure of the cooking appliance can be effectively reduced, and meanwhile, the accuracy of the detection result of the object on the cooking appliance 100, such as the pot or the baking tray and the like, can be improved.

It should be noted that, for example, the triggering unit 50 is disposed to move relative to the sensing unit 60, and the above-mentioned moving arrangement may be understood as the triggering unit 50 can move relative to the sensing unit 60.

As shown in fig. 2, a heating component 30 may be further disposed in the cavity 13 of the cooking appliance, such as the electric ceramic oven 100, the heating component 30 is electrically connected to the electric control component 40, and the electric control component 40 may be a circuit board. In this way, the electric control component 40 can control the heating power mode of the cooking appliance to be turned on or turned off by controlling the heating component 30, so as to control the cooking appliance 100 to be turned off in the idle state, so as to prevent the electric ceramic oven 100 from being heated continuously in the idle state, and thus the electric ceramic oven 100 has the characteristics of safety and energy saving. Illustratively, the heat generating component 30 may be a heat generating tray. The electric control assembly 40 may be disposed at one side of the heat generating assembly 30, and the electric control assembly 40 may control the heating power mode of the electric ceramic oven 100 to be turned on and off through the heat generating assembly 30.

Specifically, referring to fig. 2 and 3, the triggering unit 50 has a triggering member 52, and the triggering member 52 is driven by the triggering unit 50 to move relative to the sensing unit 60 to trigger the sensing unit 60. Therefore, the induction unit 60 can be triggered by the trigger 52, so that when the position of the trigger 52 relative to the induction unit 60 changes, the induction unit 60 can generate different signals, so that the electric control assembly 40 can detect an object on the cooking appliance, such as a pot or a baking tray, according to the change of the signal on the induction unit 60, so that the cooking appliance has the characteristics of safety and energy saving, and the safety factor of the cooking appliance is improved.

Further, as shown in fig. 2 and 3, the triggering unit 50 may include a supporting rod 51 disposed in the cavity 13, a first end 511 of the supporting rod 51 extending out and exposed above the panel 20, and a second end 512 of the supporting rod 51 having a triggering member 52; the supporting rod 51 is movably disposed in a vertical direction relative to the panel 20 to move the triggering member 52 relative to the sensing unit 60. The trigger 52 is disposed at the second end 512 of the supporting rod 51, and when an object such as a pot or a grill pan is placed on the cooking utensil such as the electric ceramic stove 100 and presses the first end 511 of the supporting rod 51, the supporting rod 51 can drive the trigger 52 to move relative to the sensing unit 60 so as to trigger the sensing unit 60 for detecting the object on the cooking utensil such as the pot or the grill pan.

It should be noted that the vertical direction is not an absolute direction. In this embodiment, the vertical direction may be understood as a direction perpendicular to the cooking appliance or the operating table when the cooking appliance is normally placed on the operating table.

The support rod 51 may be an integrated structure or a split structure. That is, the first end 511 and the second end 512 may be a single structure or may be separate structures connected together. Illustratively, second end 512 may be coupled to first end 511 via a screw connection, snap connection, or other coupling.

Fig. 5 is a schematic structural diagram of the detecting assembly provided in the first embodiment of the present invention, and fig. 6 is a schematic splitting diagram of the detecting assembly provided in the first embodiment of the present invention.

Referring to fig. 2 to 6, in order to remove the pot and make the rear support rod 51 automatically reset, the cavity 13 further comprises an elastic member 80, and the elastic member 80 abuts between the second end 512 and the bottom wall 11 of the housing 10. Through the arrangement of the elastic member 80, on one hand, the trigger unit 50 can be supported in the cavity 13, so that the trigger unit 50 can automatically reset after an object such as a pot or a baking tray is removed from the cooking appliance, and a signal on the sensing unit 60 can also be recovered, so that the object on the cooking appliance such as the pot or the baking tray can be detected next time, and on the other hand, the accuracy of the object detection result on the cooking appliance can be enhanced.

Meanwhile, the elastic member 80 is arranged to enable the first end 511 of the supporting rod 51 to have a certain elastic force, so as to prevent a soft object with a small mass, such as a rag, from being unable to trigger the first end 511 of the supporting rod 51, which is helpful for enhancing the accuracy of the detection result of an object, such as a pot or a baking tray, on the cooking utensil, such as the electric ceramic stove 100.

As shown in fig. 3 and 4, a side of the second end 512 facing the bottom wall 11 has a groove 5121, and the bottom wall 11 is provided with a protrusion 12 extending into the cavity 13; one end of the elastic member 80 is embedded in the groove 5121, and the other end of the elastic member 80 is sleeved on the protrusion 12. In this way, the elastic member 80 can be positioned by at least one of the groove 5121 and the protrusion 12, so as to prevent the elastic member 80 from deviating when the supporting rod 51 moves relative to the panel 20, which may affect the detection result of the object on the cooking utensil, such as a pot or a baking tray, and facilitate the assembly of the elastic member 80.

It should be noted that a fitting cavity 5122 is further disposed in the second end 512, and the groove 5121 is located at an end of the fitting cavity 5122 facing the panel 20. Thus, a portion of the elastic member 80 can be received in the assembly cavity 5122 and embedded in the groove 5121, which helps to improve the stability of the connection between the second end 512 and the bottom wall 11 of the housing 10 of the elastic member 80.

In order to support the support rod 51 in the cavity 13, as shown in fig. 2 to 6, a support sleeve 70 is further disposed in the cavity 13, the support rod 51 is disposed in the support sleeve 70 and is movable in a vertical direction relative to the support sleeve 70, and the support rod 51 is supported in the cavity 13 by the support sleeve 70. The supporting rod 51 can be further supported in the cavity 13 through the supporting sleeve 70 on the basis of the elastic member 80, and the triggering member 52 can be ensured to move relative to the sensing unit 60, so that the supporting rod 51 can be protected on one hand, and the supporting rod 51 can be guided and limited to move on the other hand.

It should be noted that, because the temperature in the cavity 13 is higher when the cooking appliance, such as the electric ceramic oven 100, is in operation, when the support sleeve 70 is a heat insulation structure made of a material with low thermal conductivity, such as ceramic, the support sleeve 70 can also play a role in protecting the support rod 51 from heat, so as to prevent the high temperature in the cavity 13 from affecting the detection result of the object on the cooking appliance, such as a pot or a baking tray.

As shown in fig. 2 to 6, the support sleeve 70 may include a first cylinder 71 and a second cylinder 72, and the second cylinder 72 communicates with the first cylinder 71 through a fitting hole 73. The first end portion 511 of the support rod 51 is fitted into the first cylinder 71 through the fitting hole 73, and the second end portion 512 is fitted into the second cylinder 72. In this way, the support rod 51 can be assembled in the support sleeve 70, so that the support rod 51 can be protected and guided by the support sleeve 70.

In order to facilitate the support rod 51 to move in the vertical direction relative to the panel 20 or the support sleeve 70 under the pressure of the pot or the grill pan, etc., a gap should be left between the support rod 51 and the fitting hole 73.

Specifically, the heating element 30 is disposed in the cavity 13, and the support sleeve 70 is disposed in the heating element 30 and detachably connected to the heating element 30. So that the supporting rod 51 and the triggering unit 50 can be fixed in the cavity 13 by the supporting sleeve 70.

As a possible embodiment, as shown in fig. 3 and 4, the circumferential side edge of the second cylinder 72 may be provided with a first assembling portion 711, the first assembling portion 711 is provided with a clamping portion 712, and the first assembling portion 711 may be clamped with the bottom of the heat generating component 30 through the clamping portion 712 to facilitate the detachment of the support sleeve 70. The engaging portion 712 can be understood as an engaging block on the first mounting portion 711.

Referring to fig. 3 to 6, the triggering member 52 may be disposed on the periphery of the second end 512, and the sensing unit 60 is disposed on the periphery of the triggering member 52 and opposite to the triggering member 52, wherein the sensing unit 60 and the triggering member 52 have a gap therebetween. Thus, when the trigger 52 moves relative to the trigger 52 under the driving of the supporting rod 51, the area or the distance between the trigger 52 and the sensing unit 60 changes, so as to cause the change of the signal on the sensing unit 60, so that the electronic control component 40 can detect an object on the cooking appliance, such as a pot or a baking tray, according to the change of the signal on the sensing unit 60, thereby controlling the closing or opening of the cooking appliance.

As a possible embodiment, the triggering member 52 may be disposed on an outer sidewall of the second end portion 512 of the supporting rod 51 (as shown in fig. 3 and 4), the second end portion 512 is disposed in the supporting sleeve 70, and the sensing unit 60 is disposed on an inner sidewall of the supporting sleeve 70. This facilitates the fixing of the trigger 52 on the second end 512 of the supporting rod 51, which is coupled with the sensing unit 60 for detecting an object on the cooking appliance, such as a pot or a grill pan. Meanwhile, the structure of the detection assembly can be more compact, so that the arrangement of other devices in the cavity 13 is facilitated.

Alternatively, the triggering member 52 may be fixed on the inner sidewall of the second end 512 of the supporting rod 51, and correspondingly, the sensing unit 60 is fixed on the side of the triggering member 52 facing the elastic member 80 (i.e. the inner side of the triggering member 52) and is disposed opposite to the triggering member 52.

Wherein the trigger 52 may be a continuous structure or an intermittent structure around the outer sidewall of the second end 512. That is, the trigger 52 may be a unitary structure, such as an electrode sheath, disposed around the exterior sidewall of the second end 512. Alternatively, the trigger 52 can be understood as a plurality of discrete structures disposed around the outer sidewall of the second end 512, and there is a space between two adjacent discrete structures. Wherein, the discrete structure can be an electrode slice. In this way, the detection of an object such as a pot or a baking tray on a cooking appliance such as the electric ceramic oven 100 is realized, so that the cooking appliance has the characteristics of safety and energy saving, and meanwhile, the structures of the trigger 52 and the trigger unit 50 can be more diversified.

To facilitate the placement of the trigger 52, the diameter of the second end 512 may be larger than the diameter of the first end 511.

When the second end 512 is a metal structure, an insulating member 53 is disposed between the trigger 52 and the second end 512, and the trigger 52 is fixed on the peripheral side of the second end 512 by the insulating member 53. Therefore, the insulation piece 53 can prevent the trigger piece 52 from being conducted with the support rod 51, so that the first end 511 of the support rod 51 is electrified, and the safety performance of the cooking appliance is improved.

Illustratively, the insulator 53 may be fixed to the periphery of the second end 512 by a snap fit or other detachable connection. The trigger member 52 may be fixed to the insulating member 53 by coating, bonding, or clipping so as to be fixed to the peripheral side of the second end portion 512 by the insulating member 53.

As a possible implementation, the detection component may be a capacitive detection component, and the triggering component 52 and the sensing unit 60 are both electrodes, at least one of which is electrically connected to the electronic control component 40. In this case, the trigger 52 may be understood as an inner electrode, and the sensing unit 60 may be understood as an outer electrode.

The magnetic conductive element may be iron or other magnetic conductive elements. The inductive element may be an inductor. Thus, when the triggering member 52 moves relative to the sensing unit 60, the distance between the triggering member 52 and the sensing unit 60 changes accordingly, so as to cause a change in the magnetic field or inductance of the sensing unit 60, so that the electronic control component 40 can detect an object on the cooking appliance, such as a pot or a baking tray, according to the change in the magnetic field or inductance.

Or, the detecting component may also be a magnetic induction detecting component, the triggering component 52 is a magnet, the sensing unit 60 is a reed pipe or a hall element, and the reed pipe or the hall element is electrically connected to the electronic control component 40. In this case, the detection assembly may be understood as a magnetic switch, in which the reed switch or the hall element is turned on when the magnet is close to the reed switch or the hall element, and is turned off when the magnet is away from the reed switch or the hall element. Thus, when the trigger 52 moves relative to the sensing unit 60, the reed switch or the hall element can be opened or closed under the action of the magnet, so that the electronic control assembly 40 can detect an object on the cooking appliance, such as a pot or a baking pan, according to the change of the reed switch or the hall element.

That is, the triggering member 52 may be an inductive element, and the sensing unit 60 may be a magnetic conducting element. The trigger 52 is a reed switch or hall element and the sensing unit 60 is a magnet.
