As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-2: fig. 1 is a partial structural schematic view of an integrated cooker 10 provided in an embodiment of the present application, and fig. 2 is another partial structural schematic view of the integrated cooker 10 provided in an embodiment of the present application. The integrated cooker 10 may include an oil container 100, a signal emitter 210, a signal receiver 220, and a float 300.

It is understood that the integrated cooker 10 may further include a housing structure, and the oil cartridge 100 may be disposed at a bottom position of the housing structure of the integrated cooker 10 to collect the oil 110. It should be noted that the oil box 100 has a side wall with a bottom wall surrounding the bottom wall, and the side wall forms a receiving space around the bottom wall, and the receiving space can receive the oil stain 110 collected by the oil stain receiving space.

The capacity of the storage space of the oil cartridge 100 is limited, and the oil contamination 110 may overflow when the amount reaches the threshold value of the capacity of the storage space of the oil cartridge 100. In order to prevent the oil stains 110 from overflowing from the oil box 100, the embodiment of the present application is provided with a signal transmitter 210 and a signal receiver 220 on a shell structure of the integrated stove 10, the signal transmitter 210 may transmit a detection signal, the signal receiver 220 may receive the detection signal transmitted by the signal transmitter 210, and the integrated stove 10 may determine whether the oil stains 110 in the oil box 100 reach a threshold value, that is, a preset amount, based on whether the signal receiver 220 receives the detection signal or based on the strength of the received detection signal. Thereby facilitating the user to clean the oil stain 110 in the oil box 100 in time according to the related prompt information.

The signal transmitter 210 may transmit a detection signal, and the detection signal transmitted by the signal transmitter 210 may be an infrared signal, or may be other signals, such as an ultrasonic signal. The signal emitter 210 may be disposed above the oil container 100, and the above may be understood as the above of the entire space of the oil container 100, or the above of the opening of the oil container 100 where the oil stain 110 is collected in the integrated range 10 after the integrated range 10 is installed.

The signal receiver 220 may receive a detection signal transmitted by the signal transmitter 210, such as an infrared signal, an ultrasonic signal, and the like. The signal receiver 220 may be disposed above the oil box 100, and the above may also be understood as the above of the whole space of the oil box 100, or as the above of the opening of the oil box 100 for collecting the oil stain 110 of the integrated range 10 after the integrated range 10 is installed.

It should be noted that the signal transmitter 210 and the signal receiver 220 should be disposed above the oil box 100 relatively and not contact the oil 110 in the oil box 100 at any time. Even if the oil contamination 110 in the oil box 100 is overflowed, the signal transmitter 210 and the signal receiver 220 are not contaminated or even soaked by the oil contamination 110, and can work normally.

In addition, the sensitivity of the signal transmitter 210 and the signal receiver 220 in terms of signal transceiving depends on the distance (medium is air) between the two in addition to whether the calibration is performed. Therefore, in order to improve the sensitivity of the signal transmitter 210 and the signal receiver 220 for transmitting and receiving signals as much as possible, the signal transmitter 210 and the signal receiver 220 may be disposed opposite to each other, and the receiving space formed between the signal receiver 220 and the signal transmitter 210 should be as small as possible.

In an alternative embodiment of the present application, a float 300 may be placed in the oil tank 100, where the float 300 refers to a marker floating on the surface of the oil 110 to indicate the level of the oil 110, and anchored at a designated location such as on or near the center axis of the oil tank 100 (i.e., between the signal transmitter 210 and the signal receiver 220) to ensure that the float 300 can be driven to block the detection signal transmitted by the signal transmitter 210 from being received by the signal receiver 220 when the amount of the oil 110 in the oil tank 100 increases to a predetermined amount.

When the oil contamination 110 is not collected in the oil tank 100, the float 300 may be directly placed on the inner surface of the bottom wall of the oil tank 100. When the oil stain 110 is collected in the oil box 100, the buoy 300 can float on the surface of the oil stain 110 collected in the oil box 100. The float 300 can move along with the change of the amount of the oil 110 collected in the oil tank 100, and the amount of the float 300 moving in the oil tank 100 is proportional to the amount of the oil 110 collected in the oil tank 100. Such as when the oil 110 collected in the oil tank 100 changes from 1 cm to 2 cm occupying the entire height of the oil tank 100, the float 300 moves 1 cm in the oil tank 100 toward the direction directly above the oil tank 100. When the oil stain 110 collected in the oil tank 100 reaches a predetermined amount, the float 300 is driven to move such that a portion of the float 300 is disposed between the signal transmitter 210 and the signal receiver 220 to block the detection signal transmitted by the signal transmitter 210, and thus the signal receiver 220 cannot receive the detection signal. Based on this integrated cooker 10, such as a processor (controller) of the integrated cooker 10, it can be determined that the oil stain 110 needs to be cleaned.

It should be noted that, when the amount of the oil stain 110 in the oil tank 100 is less than the preset amount, the buoy 300 cannot block the detection signal transmitted by the signal transmitter 210, and the signal receiver 220 receives the detection signal. The processor of the integrated cooker 10 can now determine that the oil 110 in the oil box 100 can be first cleaned.

Wherein the preset amount is the numerical amount of the oil contamination 110 about to overflow from the oil box 100.

In an alternative embodiment of the present application, when a portion of the buoy 300 is located between the signal emitter 210 and the signal receiver 220, the detection signal emitted by the signal emitter 210 may not be completely blocked, and the detection signal emitted by the signal emitter 210 may be greatly attenuated, so that the signal receiver 220 may receive the attenuated detection signal. In the embodiment of the present application, the detection signal that is not retrieved by the buoy 300 is defined as a first signal, and the detection signal attenuated by the buoy 300 is defined as a second signal. When the processor of the integrated cooker 10 receives the first signal by the signal receiver 220, it may be determined that the oil stain 110 collected by the oil tank 100 does not reach the preset amount, and the oil stain may not be cleaned. When the processor of the integrated cooker 10 receives the second signal from the signal receiver 220, it may determine that the oil stain 110 collected by the oil pan 100 reaches a preset amount, that is, needs to be cleaned.

By arranging the signal emitter 210, the signal receiver 220 and the buoy 300 in the oil box 100 of the integrated stove 10, floating on the oil stain 110 collected by the oil box 100 and moving the buoy 300 along with the change of the amount of the oil stain 110 collected by the oil box 100, whether the detection signal emitted by the signal emitter 210 is blocked is received by the signal receiver 220 or the detection signal emitted by the signal emitter 210 received by the signal receiver 220 is weakened, whether the amount of the oil stain 110 in the oil box 100 reaches a preset amount is determined, and whether a prompt is triggered to enable a user to clean the oil stain 110 in time. Compare in prior art's the mode of weighing or the light detection mode, the embodiment that this application provided simple structure, detection error is littleer, more accords with actual real situation, can indicate more accurately whether greasy dirt 110 reaches the overflowed degree and in time remind the user to clear up oil box 100, is not limited to the crowd who uses of integrated kitchen 10.

In the embodiment of the present application, in order to limit the stable movement of the buoy 300, it is ensured that the buoy 300 can be accurately placed between the signal emitter 210 and the signal receiver 220 when moving, and the function of blocking or weakening the detection signal received by the signal receiver 220 and emitted by the signal emitter 210 is performed, and the integrated cooker 10 further includes a limiting mechanism.

In an alternative embodiment of the present application, the limiting mechanism may be the side wall of the oil box 100 itself. The size of the buoy 300 can be adapted to the size of the inner cavity of the oil tank 100, such as the oil tank 100 is cylindrical, and then the buoy 300 can be set to be cylindrical, the diameter of the buoy is slightly smaller than that of the inner cavity of the oil tank 100, which just can prevent the buoy 300 or the center from shifting the central axis of the inner cavity of the oil tank 100 when moving along with the change of the amount of the oil stains 110, and does not influence the up-and-down movement of the buoy 300. Or for example, the oil tank 100 is a square including a cuboid in a square shape, the surface of the buoy 300 contacting the liquid level of the oil stain 110 is a square shape matched with the oil tank 100, and the size of the surface is slightly smaller than the size of the inner cavity of the oil tank 100, which just can prevent the center of the buoy 300 from shifting the central axis of the inner cavity of the oil tank 100 when moving along with the change of the amount of the oil stain 110, and does not influence the up-and-down movement of the buoy 300 or the base 310 of the buoy 300.

In an alternative embodiment of the present application, a limiting shaft may be disposed on the central axis of the bottom wall of the oil box 100 as the limiting mechanism. One end of the limiting shaft is fixed at the center of the bottom wall of the oil box 100, the other end is an open end, the open end or an extension line of the open end should be between the signal transmitter 210 and the signal receiver 220, and more properly, the open end or the extension line of the open end should be at the midpoint of a connecting line of two probes of the signal transmitter 210 and the signal receiver 220.

The axial center of the buoy 300 is provided with a through hole, the buoy 300 can be directly sleeved on the limit shaft through the through hole, the buoy 300 or the center of the base 310 of the buoy 300 can be just prevented from deviating from the central axis of the inner cavity of the oil box 100 when moving along with the change of the amount of the oil stain 110, and the up-and-down movement of the buoy 300 is not influenced.

In addition to the above manner, the limiting mechanism may further include a grid disposed at an axial line position in the inner cavity of the oil tank 100, and the grid is used for placing the buoy 300, so that the central axis of the inner cavity of the oil tank 100 is shifted when the buoy moves along with the change of the amount of the oil stain 110, and the up-and-down movement of the buoy 300 is not affected.

As shown in fig. 3-4: fig. 3 is a partial structural schematic view of the integrated cooker 10 provided in the embodiment of the present application, and fig. 4 is another partial structural schematic view of the integrated cooker 10 provided in the embodiment of the present application. In order to better realize that the buoy 300 can float on the oil 110, and can be effectively arranged between the signal transmitter 210 and the signal receiver 220 when the amount of the oil 110 reaches a preset amount, and does not occupy too much space. The buoy 300 of the embodiment of the present application is provided in at least two parts, such as the buoy 300 comprises a base 310 and a post 320 with one end fixed on the base 310, the base 310 can float on the oil 110 collected by the oil tank 100, and the base 310 and the post 320 can move along with the change of the amount of the oil 110 collected by the oil tank 100.

It is understood that the base 310 only serves to carry the target 320 and move the target 320 relatively according to the change of the amount of the oil 110 collected in the oil tank 100. The pole 320 has one end fixed at the center of the base 310 and the other end as an open end, and the extension line of the open end should be between the signal emitter 210 and the signal receiver 220, and more properly, the extension line of the open end should be at the midpoint of the two probe connecting lines of the signal emitter 210 and the signal receiver 220.

When the amount of oil 110 in the oil tank 100 rises between the preset value and the full value, in order to prevent the top end of the target 320 from touching the inner surface of the casing of the integrated cooker 10 or other components, which may result in damage to the target 320 or extrusion of the buoy 300 into the oil 110, the target 320 implemented in the present application may be a telescopic rod, so that the target 320 may be triggered to contract by the pressing force before the target 320 touches the inner surface of the casing of the integrated cooker 10 or other components without being damaged.

In an alternative embodiment of the present application, the post 320 includes a bottom tube and a rod portion connected to the bottom tube by a pivot assembly. The bottom tube is internally provided with a spring device which is used for enabling the rod part to automatically extend because the spring tends to be in a stable state when the rod part is not extruded by external force. When the rod part is extruded by external force, the rod part is contracted in the bottom tube, the spring is compressed at the moment, and after the external force is relieved, the rod part is extended under the action of the elastic force of the spring. Based on this, the pressing force triggers the target 320 to contract before the target 320 is damaged after touching the inner surface of the integrated cooker 10 or other components when the amount of the oil 110 in the oil tank 100 rises between the preset value and the full value.

It is emphasized that when the oil 110 reaches a preset value, the top end of the post 320 is still spaced from the inner surface of the integrated cooker 10 or other members and does not touch. At this time, the lever 320 is not triggered to contract.

The target 320 is contracted when being pressed by external force, for example, after the oil stain 110 reaches a preset value, the liquid level of the oil stain 110 continues to rise, the top end of the target 320 may be continuously lifted and finally touch the inner surface of the integrated cooker 10 shell or other components, at this time, due to the buoyancy, the inner surface of the integrated cooker 10 shell or other components reversely press the target 320, and the target 320 is triggered to be contracted.

The above is a general description of the angle of the buoy 300 and the sensor (the signal emitter 210 and the signal receiver 220) which are mutually matched to solve the problem that the oil stain 110 in the oil tank 100 is easily spilled in the related art. The following description is made in terms of both intelligently alerting the user and implementing the integrated cooker 10.

It should be noted that, in order to enable the integrated cooker 10 to intelligently remind a user, the integrated cooker 10 according to the embodiment of the present application may further include an indicator. An indicator may be mounted on the surface or inside the housing structure of the integrated cooker 10, and the indicator may display a prompt message to remind the user whether the oil stain 110 in the oil tank 100 currently exceeds a preset amount. For example, the indicator may include at least one display configured to display at least the current amount of oil 110 collected in the oil container 100, such as the amount of oil 110. It is understood that the display, i.e. the display screen, may be any one of a CRT display, an LCD display, an LED display or a 3D display, and is used for receiving a detection signal sent by a processor (controller) of the integrated cooker 10, such as the integrated cooker 10, according to the current amount of the oil contamination 110 in the oil box 100 and forming an image, i.e. displaying information whether the amount of the oil contamination 110 in the oil box 100 exceeds a preset amount to a user after visualizing the information of the amount of the oil contamination 110.

Another example of the indicator includes at least one buzzer or speaker: taking a buzzer as an example, the buzzer is an electronic buzzer with an integrated structure, and is used as a sounding device for prompting a user whether the oil stain 110 in the oil box 100 currently exceeds a preset amount. The buzzer can receive a prompt instruction which carries prompt information and is sent by a processor (controller) of the integrated cooker 10 such as the integrated cooker 10 according to a detection signal of the amount of the oil stain 110 in the oil box 100 at present, and the buzzer is controlled to sound to prompt a user that the oil stain 110 in the oil box 100 at present reaches a preset amount and needs to be cleaned. Or the processor (controller) of the integrated cooker 10 controls the frequency of sounding the buzzer through the prompt instruction carrying the prompt information to prompt the user about the amount of the oil 110 in the oil tank 100 and whether the amount exceeds the preset amount. For example, when the amount of the oil 110 in the oil box 100 does not reach the preset amount, the buzzer rings one sound every ten minutes after the integrated oven 10 is powered on (generally, the integrated oven 10 is started when the user is ready to cook and cook food); when the amount of the oil stains 110 in the current oil box 100 reaches a preset amount, the buzzer sounds three sounds every minute; when the amount of the oil 110 in the oil box 100 exceeds the preset amount and is about to overflow, one sound is given every three seconds. Therefore, the accurate prompt can be reasonably provided for the user in time, and the user is not irritated by the frequent buzzing sound.

Taking a speaker as an example, the speaker is also called a "horn", which is a very common electroacoustic transducer. By using the speaker, the electrical signal can be converted into an acoustic signal, such as a prompt instruction carrying a corresponding acoustic signal sent by the processor (controller) of the integrated cooker 10 according to the detection signal of the amount of the oil stain 110 in the oil box 100, where the acoustic signal is set in the processor (controller) loading program, so that the processor can more humanized or directly prompt the user whether the amount of the oil stain 110 in the oil box 100 exceeds the preset amount in a broadcast manner. For example, when the oil contamination 110 in the oil box 100 exceeds a preset amount, the processor (controller) directly controls the speaker to broadcast/play "the oil contamination 110 in the oil box 100 is full, please clean up in time". This is easier for those users who are not familiar with the intelligent integrated cooker 10 to understand, and can also play a role in reminding the users to clean the oil stains 110 in time.

Also for example, the reminder may include at least one indicator light. For example, the user may be prompted by the different colors of the color-changing indicator lights whether the amount of oil stain 110 in oil tank 100 exceeds a preset amount currently. Such as green, indicates that the oil contamination 110 in the oil box 100 does not reach the preset amount, and the red color scale indicates that the oil contamination 110 in the oil box 100 exceeds the preset amount. The information of whether the oil stain 110 in the oil tank 100 exceeds the preset amount currently can be prompted to the user through the flashing frequency of an indicator lamp. Such as when the oil contamination 110 in the oil box 100 does not reach the preset amount, the indicator lamp is usually on or off, and when the oil contamination 110 in the oil box 100 exceeds the preset amount, the indicator lamp flashes at a certain frequency. The greater the amount of oil contamination 110 present in the oil cartridge 100, the greater the frequency of flashing. The information that whether the oil stain 110 in the oil box 100 currently exceeds the preset amount can be prompted to the user through the number of the flashing indicating lamps. For example, the more the amount of the oil contamination 110 in the current oil box 100 is, the more the number of the flashes is, and the fully bright state indicates that the amount of the oil contamination 110 in the current oil box 100 exceeds the preset amount.

For the specific implementation of the above intelligence of the integrated cooker, corresponding circuits need to be designed for the signal transmitter, the signal receiver and the prompter, and the specific circuit structure portions are as follows.

The signal transmitter 210 may be an optical signal transmitter, such as an infrared transmitter, and the signal transmitter 210 may be an optical signal receiver, such as an infrared receiver.

Taking an infrared transmitter as the signal transmitter 210 and an infrared receiver as the signal receiver 220 as an example, the working principle of the signal transmitting circuit of the signal transmitter 210 and the signal receiving circuit of the signal receiver 220 is as follows:

when the integrated cooker processor (controller) controls the base of a triode 20 connected with an infrared transmitter (first diode 21) to be at a high level, the infrared transmitter starts to work, an infrared receiver (second diode 26) continuously receives signals, and the current is continuously increased, at the moment, the voltage of the non-inverting input end of a comparator 24 is the voltage obtained by subtracting the voltage of a fourth resistor 14 from the voltage of a power supply end 22, when the voltage of the non-inverting input end of the comparator 24 is smaller than the reference voltage, namely the voltage obtained by subtracting the voltage of a sixth resistor 16 from the voltage of the power supply end 22, the output end of the comparator 24 outputs a low level, at the moment, an indicator lamp is turned on (third diode 27), and the processor receives the low level; when the buoy 300 trigger switch blocks a receiving probe of the infrared receiver, the voltage of the non-inverting input end of the comparator 24 is close to the voltage of the power supply end 22, at the moment, the voltage of the non-inverting input end of the comparator 24 is larger than the reference voltage, the output end of the comparator 24 outputs a high level, and when the processor detects the high level, the oil stain 110 in the oil box exceeds the preset amount, so that a corresponding prompt instruction is triggered.
