Description

Technical Field

[0002] A stove, also known as a cooker, is a gas appliance that converts the chemical energy of gas into thermal energy to cook dishes and process food to meet household needs. According to the type of gas used by the stove, stoves can generally be divided into natural gas stoves, artificial gas stoves, liquefied petroleum gas stoves and electromagnetic stoves. During use, the stove knob adjusts the cooking power at the current moment. The stove automatically collects cooking information such as the cooking power and cooking time at this time, and determines whether it is necessary to turn off the fire at a time and the corresponding time to turn off the fire according to the collected cooking information.

[0003] Among them, a common stove uses a camera to identify the stove knob and collect the rotation angle of the stove knob. Since cooking is mostly a high-temperature and high-pressure operation, a large amount of water vapor, oil smoke and other obstructions are often generated during the use of the stove. These obstructions will block the stove knob and affect the camera's recognition of the rotation angle of the stove knob, which will in turn affect the stove's judgment on whether it is necessary to turn off the fire at a time and the corresponding timed shutdown time, which may cause the cooking time of the ingredients to be too long or too short, the stove to burn dry, and even pose a fire hazard.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described here can be implemented in an order other than those illustrated or described here. In addition, in the description of the present embodiment, unless otherwise specified, "plurality" means two or more. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system or product including a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0042] In order to make the purpose, technical solution and advantages disclosed in the embodiments of the present application more clearly understood, the embodiments of the present application are further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of the present application and are not used to limit the embodiments of the present application.

[0043] See also Figure 1 , Figure 1 Schematic diagram of a firepower identification device provided in an embodiment of the present application. Figure 1 As shown, the fire power identification device includes a rotor assembly 1, a detection assembly 2 and a base 3. The rotor assembly 1 can be used to connect with a stove knob. Specifically, the rotor assembly 1 can be used to be fixedly connected with the stove knob by bolting, snapping or welding. The rotor assembly 1 and the stove knob can rotate synchronously.

[0044] In a possible embodiment, the detection assembly 2 may be disposed on the base 3. The detection assembly 2 includes at least one detection element 21, and each detection element 21 is used to contact or separate from the rotor assembly 1. The detection assembly 2 is used to determine the rotation angle of the cooker knob based on the connection state between the rotor assembly 1 and each detection element 21, and then identify the fire power.

[0045] The rotor assembly 1 can be rotated 360° along a preset direction with a specific rotation angle as the starting angle, and the detection elements 21 are dispersedly arranged on the rotation path of the rotor assembly 1 along the preset direction, and the preset direction may include clockwise and counterclockwise. Different connection relationships between the rotor assembly 1 and each detection element 21 correspond to different rotation angles of the stove knob. When the rotor assembly 1 rotates to different angles, the connection relationship between the rotor assembly 1 and each detection element 21 changes. The detection assembly 2 can determine the rotation angle of the stove knob by identifying the relationship between the rotor assembly 1 and each detection element 21.

[0046] Optionally, the detection component 2 may include a detection element 21. When the detection element 21 is connected to the rotor component 1, the rotation angle of the stove knob is within a first angle range. When the stove knob is separated from the rotor component 1, the rotation angle of the stove knob is outside the first angle range.

[0047] Optionally, the detection component 2 may also include two detection elements 21, which may include a first detection element and a second detection element. When the first detection element and the second detection element are both connected to the stove knob, the rotation angle of the stove knob is within a second angle range. When the first detection element is connected to the stove knob and the second detection element is separated from the stove knob, the rotation angle of the stove knob is within a third angle range. When the second detection element is connected to the stove knob and the first detection element is separated from the stove knob, the rotation angle of the stove knob is within a fourth angle range. When the first detection element and the second detection element are both separated from the stove knob, the rotation angle of the stove knob is within a fifth angle range.

[0048] In a possible embodiment, the detection component 2 includes at least two detection elements 21, and the at least two detection elements 21 are dispersedly arranged around the rotor component 1. The detection elements 21 can be dispersedly arranged on the rotation path of the rotor component 1 with the rotor component 1 as the axis, and every two adjacent detection elements 21 in the at least two detection elements 21 are spaced apart by a preset angle.

[0049] The spacing angle between adjacent detection elements 21 is the angle of the center angle of the circle between adjacent detection elements 21 when the axis of the valve stem 11 is the center of the circle. When the detection assembly 2 includes no less than three detection elements 21, the preset angle between every two adjacent detection elements 21 can be different values. Specifically, the detection assembly 2 can include four detection elements 21, and the four detection elements 21 sequentially constitute three groups of adjacent detection elements 21, and the preset angles between the three groups of adjacent detection elements 21 can be 30°, 40°, and 60°, respectively.

[0050] Optionally, when the stove knob is rotated to different angles, the connection relationship between the detection element 21 and the rotor assembly 1 changes, and the detection element 2 can recognize the rotation angle of the stove knob based on the connection relationship between the detection element 21 and the rotor assembly 1.

[0051] Optionally, the detection component 2 may include at least three detection elements 21. When the number of detection elements 21 included in the detection component 2 is greater, the number of angle partitions of the rotor component 1 corresponding to different rotation angles of the stove knob will be greater, and more accurate firepower identification can be achieved.

[0052] In a specific embodiment, the detection assembly 2 includes two detection elements 21. When both detection elements 21 are in contact with the rotor assembly 1, the rotation angle is within a first preset angle range, the firepower is in a first preset state, and the first preset state may be "fire off". When any one of the two detection elements 21 is in contact with the rotor assembly 1 and the other detection element 21 is separated from the rotor assembly 1, the rotation angle is within a second preset angle range, the firepower is in a second preset state, and the second preset state may be "medium or small fire". When both detection elements 21 are separated from the rotor assembly 1, the rotation angle is within a third preset angle range, the firepower is in a third preset state, and the third preset state may be "high fire".

[0053] Optionally, the contact and separation between the two detection elements 21 and the rotor assembly 1 directly corresponds to the state of firepower, so the state of firepower can be effectively identified based on the contact and separation between each detection element 21 and the rotor assembly 1.

[0054] See also Figure 2 , Figure 2 Schematic diagram of the installation of a firepower identification device provided in an embodiment of the present application. Figure 2 As shown, in a possible embodiment, the rotor assembly 1 includes a valve stem 11, and the valve stem 11 is used to be connected to the stove knob 4. The valve stem 11 can be fixedly connected to the stove knob 4, or the valve stem 11 can be detachably connected to the stove knob 4.

[0055] Optionally, the valve stem 11 may be arranged at the bottom of the stove knob 4, one end of the valve stem 11 is fixedly connected to the stove knob 4, and the valve stem 11 and the stove knob 4 can rotate synchronously, thereby transmitting the rotation angle of the stove knob 4, so as to facilitate detection by the detection component 2. The other end of the valve stem 11 is movably arranged on the base 3. The base 3 may include a limiting hole for fixing the valve stem 11, and the other end of the valve stem 11 may be movably arranged in the limiting hole so as to achieve the limiting of the valve stem 11 by the base 3.

[0056] In a possible embodiment, the rotor assembly 1 includes a segmented flange 12 arranged around the side surface of the valve stem 11, and the segmented flange 12 is used to contact or separate from the detection element 21. Specifically, the segmented flange 12 can be a flange structure provided with a notch. The segmented flange 12 can rotate synchronously with the valve stem 11, and the detection element 21 can include a micro switch. When the segmented flange 12 contacts the detection element 21, the segmented flange 12 abuts against the micro switch, and when the segmented flange 12 separates from the detection element 21, the micro switch rebounds.

[0057] Optionally, the contact and separation between the segmented flange 12 and each detection component 21 directly corresponds to the state of firepower, so the state of firepower can be effectively identified based on the contact and separation between the segmented flange 12 and each detection component 21.

[0058] In a possible embodiment, the central angle of the segmented flange 12 is less than 360°.

[0059] Optionally, the segmented flange 12 can be regarded as a flange structure provided with a notch portion, and the sum of the central angle of the notch portion and the central angle of the segmented flange 12 is 360°, that is, the central angle of the segmented flange 12 is less than 360°. Taking a specific detection element 21 as an example, the detection element 21 can be arranged at the bottom of the segmented flange 12, and when the segmented flange 12 is located directly above the detection element 21, the detection element 21 is in contact with the segmented flange 12, and when the notch portion is located directly above the detection element 21, the detection element 21 is separated from the segmented flange 12, thereby realizing the contact and separation of the detection element 21 and the segmented flange 12.

[0060] In a possible embodiment, the detection assembly 2 includes two detection elements 21, and the sum of the interval angle between the two detection elements 21 and the center angle of the segmented flange 12 is less than 360°. Specifically, the interval angle between the two detection elements 21 may be 45 degrees, and the center angle corresponding to the segmented flange 12 may be 255 degrees.

[0061] The spacing angle between the two detection elements 21 and the center angle of the segmented flange 12 are controlled so that the sum of the spacing angle between the two detection elements 21 and the center angle of the segmented flange 12 is less than 360°, so that the two detection elements 21 can be separated from the segmented flange 12 at the same time, thereby achieving complete separation of the detection assembly 2 and the rotor assembly 1. In other embodiments, when the sum of the spacing angle between the two detection elements 21 and the center angle of the segmented flange 12 is greater than or equal to 360°, during the rotation of the rotor assembly 1, one or two of the two detection elements 21 are always in contact with the segmented flange 12, and there is no situation where the two detection elements 21 are separated from the segmented flange 12 at the same time.

[0062] See also Figure 3 , Figure 3 Schematic diagram of the circuit structure of a detection element of a firepower identification device provided by the present application. Figure 3 As shown, the detection element 21 may include a micro switch SA. The micro switch SA may be fixedly arranged on the base 3, and the micro switch SA is used to abut or separate from the rotor assembly 1. The detection assembly 2 may include a detector, and the micro switch SA included in each detection element 21 may be electrically connected to the detector.

[0063] In a possible embodiment, the connection circuit of the micro switch SA may include a power supply voltage VDD, a pull-up resistor R, and an input / output port I / O, wherein a first end of the pull-up resistor R is connected to the power supply voltage VDD, and a second end of the pull-up resistor R is respectively connected to a first end of the micro switch SA and the input / output port I / O. A second end of the micro switch SA is grounded.

[0064] In this embodiment, the voltage of the input / output port I / O is directly related to the state of the micro switch SA, and the state of the micro switch SA can be detected based on the voltage of the input / output port I / O. When each micro switch SA is closed, the input / output port I / O is at a low level, and when each micro switch SA is open, the input / output port I / O is at a high level.

[0065] Optionally, the input / output port I / O may be electrically connected to a detector. When the input / output port I / O is at a high level, the detector detects that the micro switch SA is disconnected, and when the input / output port I / O is at a low level, the detector detects that the micro switch SA is closed.

[0066] In a possible embodiment, the fire power identification device further includes an electric control system, and the electric control system can be used to control the fire power of the stove.

[0067] Optionally, the electronic control system controls the firepower of the stove based on the firepower identified by the firepower identification device, and the electronic control system can control the firepower of the stove by adjusting the firepower of the stove up or down, turning the firepower of the stove on or off, etc. The electronic control system can be used to detect the cooking temperature, cooking time and other information at this time.

[0068] Optionally, the electronic control system is electrically connected to the detection component 2, and the electronic control system can start the timing function according to the firepower detected by the detection component 2. When the firepower detected by the detection component 2 is large, the electronic control system will turn off the firepower of the stove after a first preset time. When the firepower detected by the detection component 2 is small, the electronic control system will turn off the firepower of the stove after a second preset time. The first preset time can be less than the second preset time.

[0069] Optionally, the electronic control system can identify the current firepower based on the firepower identification device, and shut down the fire at a scheduled time according to the current firepower, so that the stove can automatically shut down when unattended, thereby improving the safety of the stove during use.

[0070] In a specific embodiment, the detection assembly 2 may include two detection elements 21, and the two detection elements may include a detection element A and a detection element B. Figure 4 , Figure 4 This is a schematic diagram of the movement of a rotor assembly of a firepower identification device provided in an embodiment of the present application. Figure 1 When the segmented flange 12 rotates to Figure 4 In the position shown, the rotation angle of the stove knob 4 connected to the rotor assembly 1 is 0 degrees. At this time, the detection element A and the detection element B are both in contact with the segmented flange 12, and the stove is in the "fire-off state".

[0071] See also Figure 5 , Figure 5 This is a schematic diagram of the movement of a rotor assembly of a firepower identification device provided in an embodiment of the present application. Figure 2 When the segmented flange 12 rotates counterclockwise to Figure 5 When the stove is in the position shown and continues to rotate, the rotation angle of the stove knob 4 connected to the rotor assembly 1 is 25 degrees, the detection element A is separated from the segmented flange 12, and the detection element B is in contact with the segmented flange 12, and the stove changes from the "fire-off state" to the "medium-low fire state".

[0072] See also Figure 6 , Figure 6 This is a schematic diagram of the movement of a rotor assembly of a firepower identification device provided in an embodiment of the present application. Figure 3 When the segmented flange 12 rotates counterclockwise to Figure 6 When the stove knob 4 connected to the rotor assembly 1 is in the position shown and continues to rotate, the rotation angle of the stove knob 4 is 70 degrees, the detection element A and the detection element B are separated from the segmented flange 12, and the stove changes from the "medium or small fire state" to the "high fire state".

[0073] See also Figure 7 , Figure 7 This is a schematic diagram of the movement of a rotor assembly of a firepower identification device provided in an embodiment of the present application. Figure 4 When the segmented flange 12 rotates counterclockwise to Figure 7 When the stove is in the position shown and continues to rotate, the rotation angle of the stove knob 4 connected to the rotor assembly 1 is 100 degrees, the detection element A contacts the segmented flange 12, and the detection element B separates from the segmented flange 12, and the stove is always in the "high fire state".

[0074] See also Figure 8 , Figure 8 This is a schematic diagram of the movement of a rotor assembly of a firepower identification device provided in an embodiment of the present application. Figure 5 When the segmented flange 12 rotates counterclockwise to Figure 8 When the stove knob 4 connected to the rotor assembly 1 is in the position shown and continues to rotate, the rotation angle of the stove knob 4 is 100 degrees, the detection element A contacts the segmented flange 12, and the detection element B separates from the segmented flange 12, and the stove changes from the "high fire state" to the "medium or low fire state".

[0075] Optionally, the detection element 21 may further include a detector, and the detector may be electrically connected to the two detection elements 21, and each detection element 21 may include a first state and a second state. When the detection element 21 is in the first state, the detection element 21 sends a first signal to the detector, and when the detection element 21 is in the second state, the detection element 21 sends a second signal to the detector. Wherein, the first state is contact, the first signal is "low level", the second state is separation, and the second signal is "high level". Table 1 is a correspondence table of a knob rotation angle, a detection element state, and a firepower size provided in the present application.

[0076] Table 1: Correspondence between knob rotation angle, detection element status and firepower

[0077] Knob rotation angle a Detection element A Detection element B Firepower 0≤a≤25° Contact (Low level) Contact (Low level) Turn off the heat 25＜a≤70° Separation (high level) Contact (Low level) Medium or small fire 70＜a≤130° Separation (high level) Separation (high level) fire 130＜a≤180° Contact (Low level) Separation (high level) Medium or small fire

[0078] Optionally, when the firepower is "off", the electronic control system executes a first strategy, which includes standby. When the firepower is "medium or small", the electronic control system executes a second strategy, which includes automatically turning off the fire after a first preset time, and the first preset time may be 5 hours. When the firepower is "high", the electronic control system executes a third strategy, which may include automatically turning off the fire after a second preset time, and the second preset time may be less than the first preset time, and the second preset time may be 1 hour.

[0079] Optionally, the detection element includes a micro switch, and the detector can be used to detect the voltage of the micro switch. When the micro switch is in the "off" state, the micro switch is in a high level state, and the detector receives a signal "1" sent by the micro switch. When the micro switch is in the "closed" state, the micro switch is in a low level state, and the detector receives a signal "0" sent by the micro switch. Detection element A may include a first micro switch, and detection element B may include a second micro switch, and the first micro switch and the second micro switch are both electrically connected to the detector. The detector performs a NAND and an XOR operation based on the received signal of the first micro switch and the second micro switch signal, and determines whether the cooker is in the firing state at the current moment based on the operation result of the NAND operation, and determines the firepower of the cooker at the current moment based on the operation result of the XOR operation. Table 2 is a correspondence table of a detector receiving signal, a NAND operation result, an XOR operation result, and a firepower size provided in an embodiment of the present application.

[0080] Table 2: Correspondence between the detector receiving signal, the result of the AND-NOT operation, the result of the XOR operation and the firepower

[0081] First micro switch signal Second micro switch signal The result of the AND NOT operation XOR operation result Firepower 1 1 0 0 Turn off the heat 0 1 1 1 Medium or small fire 0 0 1 0 fire 1 0 1 1 Medium or small fire

[0082] When the first micro switch is open and the second micro switch is open, the first micro switch signal is 1 and the second micro switch signal is 1. When the first micro switch is closed and the second micro switch is open, the first micro switch signal is 0 and the second micro switch signal is 1. When the first micro switch is closed and the second micro switch is closed, the first micro switch signal is 0 and the second micro switch signal is 0. When the first micro switch is open and the second micro switch is closed, the first micro switch signal is 1 and the second micro switch signal is 0.

[0083] The detector can perform a NAND or XOR operation on the received first microswitch signal and the second microswitch signal. When the NAND result is 1, the corresponding stove is in the "fire" state, and when the NAND result is 0, the corresponding stove is in the "fire-free" state. On the premise that the NAND result is 1, when the XOR result is "1", the corresponding fire power is "medium or small fire", and when the XOR result is "0", the corresponding fire power is "high fire".

[0084] In the second aspect, the utility model discloses a stove, which includes any one of the firepower identification devices mentioned above. The stove can identify the size of the firepower at the current moment through the firepower identification device, and control the size of the firepower through an electronic control system. The stove can be turned on and off through the electronic control system, thereby realizing automatic shutdown of the stove when there is no one on duty.
