Referring to fig. 1 to 6, the present invention provides an electric ceramic oven in whole and partial structure. As can be seen from fig. 1 to 3, a cooking appliance such as an electric ceramic oven 100 may include a housing 10 and a panel 20, the panel 20 is covered on the housing 10 and forms a cavity 13 with the housing 10, a trigger assembly 50, an electric control assembly 40 and a sensing assembly are arranged in the cavity 13, and the sensing assembly is electrically connected with the electric control assembly 40.

The first end 511 of the triggering component 50 extends out and is exposed on the panel 20, the second end 512 of the triggering component 50 is provided with a blocking member 52, and the blocking member 52 is movably arranged relative to the light path 73 of the sensing component to control the on-off state of the light path 73. When a pot, a baking tray or other objects with a certain weight are placed on the panel 20, the first end 511 is pressed to drive the blocking member 52 to move towards the bottom wall 11 of the housing 10 in the cavity 13, the blocking member 52 moves relative to the light path 73 of the sensing assembly, so that the on-off state of the light path 73 can be controlled by the blocking member 52, so that the signal on the sensing assembly changes between the loading state and the idle state of the cooking appliance, and the electric control assembly 40 can detect the object on the cooking appliance, such as the pot or the baking tray, on the cooking appliance, such as the electric ceramic oven 100, according to the change of the signal on the sensing assembly, so as to control the closing or opening of the heating power of the cooking appliance through the electric control assembly 40. Therefore, when the cooking appliance is in an idle state, the electric control assembly 40 can control the cooking appliance to be closed, so that the cooking appliance has the characteristics of safety and energy conservation.

Meanwhile, because block and trigger for contactless between 52 and the response subassembly, consequently compare in the prior art in order to realize the detection of pan mechanical transmission structure that sets up in cooking utensil such as electric ceramic stove 100, the utility model discloses not only can make cooking utensil simple structure, help improving the accuracy of the object on the cooking utensil such as detection results such as pan or overware moreover.

Wherein, cooking utensil is in the state of bearing can be understood as the cooking utensil and has placed the state that pan or overware etc. were located. Correspondingly, cooking utensil is in the idle state can be understood as the cooking utensil and has not placed the state that pan or overware etc. were located.

It should be noted that, for example, the blocking member 52 is disposed to move relative to the optical path 73 of the sensing component, and the moving arrangement in the above description may be understood as the blocking member 52 can move relative to the optical path 73 of the sensing component.

Wherein, a heating area 21 is provided on the panel 20, so that a pot or a baking tray can be placed in the heating area 21 to heat food in the pot or the baking tray.

In order to facilitate the first end 511 to extend out and expose on the panel 20, a through hole (not shown in the figure) for the first end 511 to pass through should be opened in the heating region 21 of the panel 20.

The through hole can be formed in the middle of the heating region 21, so that the trigger assembly 50 can penetrate through the middle of the panel 20 and the cavity 13, the trigger assembly 50 is fixed in the cavity 13, the stress of the trigger assembly 50 can be more uniform, and the accuracy of the detection result of the object on the ceramic furnace can be improved.

The heating area 21 is understood to be an area occupied by an effective heating area on the panel 20.

Wherein the blocking member 52 is located in the optical path 73, and after the blocking member 52 is moved relative to the optical path 73, the blocking member 52 is located outside the optical path 73 and is disposed toward one side of the bottom wall 11 of the housing 10.

Alternatively, the blocking member 52 is positioned outside the optical path 73 and toward a side of the panel 20, and the blocking member 52 is positioned within the optical path 73 after the blocking member 52 is moved relative to the optical path 73.

Therefore, when a cooking appliance such as the electric ceramic oven 100 is in an idle state, the light path 73 can be in a normally-on state or a normally-off state, when the cooking appliance is in a carrying state, under the pressure action of a pot, a baking tray or other objects with certain weight, the blocking part 52 can move relative to the sensing component, so that the light path 73 in the normally-on state or the light path 73 in the normally-off state is blocked by the blocking part 52, the on-off state of the light path 73 is controlled, the signal of the sensing component can be correspondingly controlled, the detection of the objects on the cooking appliance such as the pot, the baking tray and the like is realized, and meanwhile, the structure of the cooking appliance can be more diversified.

It should be understood that whether the light path 73 is normally on or normally off when the cooking appliance is in the unloaded state depends primarily on the initial position of the blocking member 52 and the position of the sensing assembly relative to the blocking member 52, and in this embodiment, whether the light path 73 is normally on or normally off when the heating region 21 is in the unloaded state is not further limited.

Referring to fig. 3 to 6, the triggering assembly 50 includes a supporting rod 51 and a blocking member 52, the supporting rod 51 is disposed in the cavity 13 and is vertically movably disposed relative to the sensing assembly in the cavity 13, an end of the supporting rod 51 facing the panel 20 is a first end 511, an end of the supporting rod 51 facing the bottom wall 11 of the housing 10 is a second end 512, and the blocking member 52 is perpendicularly disposed on a side of the second end 512 and extends in a direction of the light path 73. When placing the pan like this on heating region 21, the first end 511 of bracing piece 51 can with the bottom butt of pan or overware to drive under the pressure of pan or overware and block the direction removal that 52 moved towards casing 10 diapire 11, make and block 52 and taken place the removal for the position of response subassembly, so that control the on-off state of light path 73 through blocking 52, thereby realize the detection of the object on the cooking utensil such as pan or overware etc..

The blocking member 52 is a blocking block extending toward the light path 73 on the side of the second end 512, or other structural members capable of blocking the light path 73. This can make the blocking member 52 more effective in blocking or reflecting the detection light.

Further, referring to fig. 3 to 6, the trigger assembly 50 further includes a mounting sleeve 53, and the support rod 51 is inserted into the mounting sleeve 53 and supported in the cavity 13 through the mounting sleeve 53. The support rod 51 is thus supported within the cavity 13 by the mounting sleeve 53.

Specifically, the mounting sleeve 53 is further provided with a mounting portion 531 on the peripheral side thereof, and the mounting sleeve 53 is detachably mounted on the side of the heat generating component 30 facing the bottom wall 11 of the housing 10 (i.e., the bottom surface of the heat generating component 30) through the mounting portion 531 so as to trigger the detachment of the component 50. Illustratively, the mounting portion 531 may be detachably connected to the heat generating component 30 by a fastener such as a screw or a bolt.

Wherein, the side wall of the mounting sleeve 53 is provided with an orientation groove 532, and the blocking member 52 is positioned at the side of the support rod 51 and extends out of the mounting sleeve 53 through the orientation groove 532. Therefore, the orientation groove 532 can make the blocking member 52 extend out of the mounting sleeve 53 and move relative to the sensing assembly, which is helpful for detecting the object on the cooking utensil 100, and can limit the movement of the blocking member 52. At the same time, the rotation angle of the blocking member 52 relative to the sensing assembly can also be positioned by controlling the position of the orientation slot 532 so that the blocking member 52 can reflect the detected light to the receiving unit 70.

Wherein the orientation slot 532 may be a slot-type structure that fits the stop member 52. When the blocking member 52 is a bar-shaped blocking piece, the directional slot 532 may be a bar-shaped slot adapted to the width of the blocking piece, and the slot length of the bar-shaped slot is greater than the height of the blocking piece, so that the blocking piece can move in the directional slot 532 relative to the sensing assembly, so as to better limit the movement of the blocking member 52.

It should be noted that the height direction of the blocking piece is consistent with the moving direction of the blocking piece 52 in the cavity 13.

To reduce the weight of the trigger assembly 50, the blocking member 52 may be a hollow blocking member, which facilitates quick resetting of the support bar 51 assembly without affecting the detection of objects on the cooking appliance.

Specifically, a heating component 30 electrically connected with the electronic control component 40 is further arranged in the cavity 13, and the mounting sleeve 53 is detachably connected with the bottom of the heating component 30. Therefore, the heating assembly 30 can facilitate the fixing of the mounting sleeve 53 and the trigger assembly 50 in the cavity 13, and the electric control assembly 40 can control the heating assembly 30 to turn on or off the heating power of the cooking appliance, so as to control the cooking appliance to be turned on or off.

Wherein, the heat generating component 30 may be a hob of a cooking appliance such as the electric ceramic oven 100, and the electric control component 40 may be a circuit board of the cooking appliance such as the electric ceramic oven 100.

Further, the triggering component 50 further includes a protecting sleeve 54 connected to the panel 20, and the protecting sleeve 54 is sleeved on the supporting rod 51 and located in the heating component 30. Can carry out thermal-insulated protection to bracing piece 51 through protective sheath 54 on the one hand like this, help improving cooking utensil's factor of safety, on the other hand can play spacing effect to the removal of bracing piece 51 in cavity 13.

It should be noted that the protective sheath 54 may be made of a material with low thermal conductivity, such as ceramic, in the prior art, so as to protect the support rod 51 from heat.

In order to facilitate the resetting of the trigger assembly 50, as shown in fig. 3 to 6, the retraction assembly further comprises an elastic member 55 at least partially located below the blocking member 52, and the elastic member 55 abuts between the support rod 51 and the bottom wall 11 of the housing 10. Therefore, the supporting rod 51 can be supported in the cavity 13 through the elastic member 55, so that the automatic resetting of the triggering component 50 is facilitated under the action of the elastic member 55 after the cookware or the baking tray and the like are removed from the cooking appliance, and the detection of the object on the cooking appliance such as the cookware or the baking tray and the like is facilitated next time, and on the other hand, the first end 511 of the supporting rod 51 can have certain elastic force, so that the first end 511 of the supporting rod 51 is prevented from being triggered by a soft object with small mass such as a cleaning cloth and the like, and the accuracy of the object detection result on the cooking appliance is enhanced.

One end of the elastic member 55 may be connected to the second end 512 of the supporting rod 51, and the other end of the elastic member 55 may also abut against the bottom wall 11 of the housing 10, so that the elastic member 55 may be fixed and abut between the supporting rod 51 and the bottom wall 11 of the housing 10.

For example, when one end of the elastic member 55 can be connected to the second end 512 of the supporting rod 51, one end of the elastic member 55 can be embedded inside the second end 512 of the supporting rod 51, or one end of the elastic member 55 can be sleeved outside the second end 512 of the supporting rod 51. The elastic member 55 may be a spring or other elastic structure.

Specifically, referring to fig. 3 to 6, the sensing assembly includes a transmitting unit 60 and a receiving unit 70, the receiving unit 70 receives the detection light transmitted by the transmitting unit 60, and a transmission path of the detection light between the transmitting unit 60 and the receiving unit 70 forms a light path 73. Therefore, when the blocking member 52 moves relative to the light path 73 under the action of a pot or a baking pan and the like to control the on-off state of the light path 73, the condition of the detection light received by the receiving unit 70 changes correspondingly, and the electronic control component 40 can realize the detection of an object on the cooking appliance, such as the pot or the baking pan and the like, according to the condition that the receiving unit 70 receives the detection light, so that when the cooking appliance is in an idle state, the cooking appliance can be controlled to be closed through the electronic control component 40, and the cooking appliance has the characteristics of safety and energy saving.

It should be noted that the detection light received by the receiving unit 70 can be understood as a signal of the sensing component.

In order to reduce scattering of the detection light, the detection light may be electromagnetic waves, infrared light, laser light, ultrasonic waves, or other light sources with good directionality. Accordingly, the transmitting unit 60 may employ an electromagnetic wave transmitter, an infrared light transmitter, a laser transmitter, or an ultrasonic transmitter. The receiving unit 70 may be an electromagnetic wave receiver, an infrared light receiver, a laser light receiver, or an ultrasonic wave receiver. Therefore, the detection light has good directionality, and when the object on the cooking appliance, such as a pot or a baking tray, is detected, the detection light can be transmitted along the preset light path 73, so that the loss of the detection light in transmission is reduced, and the accuracy of the detection result of the object on the cooking appliance, such as a pot or a baking tray, is further improved.

Specifically, as one possible embodiment, the transmitting unit 60 and the receiving unit 70 may be located on opposite sides of the blocking member 52, as shown in fig. 3 and 6. When a pot or a baking tray is placed on the heating area 21, the supporting rod 51 is pressed to drive the blocking piece 52 to move towards the bottom wall 11 of the housing 10, the blocking piece 52 can block the transmission of the detection light in the light path 73 to block the normally-on light path 73 or the light path 73 in a normally-off state, so that the reception of the detection light by the receiving unit 70 is affected, and thus the detection light received by the receiving unit 70 is changed when the cooking appliance is in an unloaded state and a loaded state, so as to realize the detection of an object on the cooking appliance, such as a pot or a baking tray.

When the cooking appliance is in an unloaded state and the blocking member 52 is located outside the light path 73 and is disposed toward one side of the panel 20 (i.e., the blocking member 52 is located above the light path 73 in fig. 3 and 4), the light path 73 is in a normally open state, and the detection light can be transmitted to the receiving unit 70. When the blocking member 52 moves into the light path 73 under the pressure of the pot, the blocking member 52 can block the light path 73 in the normal state, and the detection light cannot be transmitted to the receiving unit 70.

Accordingly, when the cooking appliance is in the unloaded state and the blocking member 52 is located in the light path 73, the light path 73 is normally off, and the detection light cannot be transmitted to the receiving unit 70. When the blocking member 52 moves to the outside under the pressure of the pot (i.e. the blocking member 52 is located below the light path 73 in fig. 3 and 4), the blocking member 52 can communicate with the normally-off light path 73, and the detection light can be transmitted to the receiving unit 70.

Alternatively, as another possible embodiment, the transmitting unit 60 and the receiving unit 70 may be located on the same side of the blocking member 52, and the blocking member is a reflecting member capable of reflecting the detection light, and reflects the detection light emitted from the transmitting unit 60 to the receiving unit 70. This enables the structure of the cooking appliance 100 to be more diversified while enabling detection of an object on the cooking appliance 100, such as a pot or a grill pan.

It should be understood that, when the transmitting unit 60 and the receiving unit 70 can be located on the same side of the blocking member 52, the blocking member 52 can reflect the detecting light emitted by the transmitting unit 60 to the receiving unit 70 by adjusting the angle of the blocking member 52 relative to the transmitting unit 60 and the receiving unit 70, so that the detecting light received by the receiving unit 70 changes when the cooking appliance 100 is in the unloaded state and the loaded state.

It should be noted that, when the transmitting unit 60 and the receiving unit 70 may also be located on the same side of the blocking member 52, the on-off state of the optical path 73 is just opposite to that when the transmitting unit 60 and the receiving unit 70 may be located on opposite sides of the blocking member 52. When the heating region 21 is in an idle state and the blocking member 52 is located outside the optical path 73 and is disposed toward one side of the panel 20, the optical path 73 is in a normally-off state. When heating region 21 is in the idle state and blocking member 52 is located in optical path 73, optical path 73 is in the normal on state.
