Description

Technical Field

[0001] The invention belongs to the technical field of electric ceramic stoves, and in particular relates to a method for quickly identifying the type of a stove plate of an electric ceramic stove. Background Art

[0002] Currently, the electric ceramic stoves on the market can be divided into two types according to the different temperature control methods of the stove plate: mechanical plate and electronic plate. Mechanical plate electric ceramic stoves use temperature control tubes to measure and control the stove temperature, while electronic plate electric ceramic stoves use thyristors to measure and control the stove temperature.

[0003] Among them, the control panels of electronic disc electric ceramic stoves and mechanical disc electric ceramic stoves generally adopt two configuration methods:

[0004] The first type: The electronic disc-type ceramic stove and the mechanical disc-type ceramic stove use two different hardware control boards, which use different bills of materials and different programs. This configuration method increases production management costs, has certain limitations, and needs further improvement.

[0005] The second type: Electronic and mechanical disc electric ceramic stoves use a single control board with the same hardware, but the programs used by the two control boards are different. The two control boards still need to be named with different material codes and undergo separate warehousing and production management. In addition, since the control boards used by electronic and mechanical disc electric ceramic stoves are the same in appearance, there is also the possibility of confusion between them. This also has certain limitations and therefore needs further improvement. Summary of the Invention

[0006] The present invention aims to overcome the shortcomings of the above-mentioned prior art and provide a method for quickly identifying the type of electric ceramic stove hob. The method distinguishes between electronic and mechanical ceramic stoves by checking whether an identification element is connected to a control panel, thereby enabling quick identification of the type of electric ceramic stove hob.

[0007] To achieve the above object, the technical solution provided by the present invention is:

[0008] A method for quickly identifying the type of an electric ceramic stove hob comprises the following steps:

[0009] A. The control panel of the electric ceramic stove is used to input the electronic disc program for controlling the operation of the electronic disc electric ceramic stove, the mechanical disc program for controlling the operation of the mechanical disc electric ceramic stove, and the identification program for distinguishing between the electronic disc electric ceramic stove and the mechanical disc electric ceramic stove;

[0010] B. When assembling an electric ceramic stove, electronic disc electric ceramic stoves and mechanical disc electric ceramic stoves are distinguished by whether an identification element is further installed. The identification element is used to connect to the control board. When the control board is started, an identification program detects whether the identification element is connected to the control board;

[0011] When the control panel detects the presence of the identification element, it determines that the electric ceramic stove is an electronic disc type electric ceramic stove and the control panel executes the electronic disc program. When the control panel does not detect the identification element, it determines that the electric ceramic stove is a mechanical disc type electric ceramic stove and the control panel executes the mechanical disc program.

[0012] Alternatively, when the control panel detects the presence of the identification element, it determines that the electric ceramic stove is a mechanical disc type electric ceramic stove, and the control panel executes the mechanical disc program. When the control panel does not detect the identification element, it determines that the electric ceramic stove is an electronic disc type electric ceramic stove, and the control panel executes the electronic disc program.

[0013] Furthermore, the identification element is a selection resistor, the single chip microcomputer of the control board is connected to one end of the selection resistor, and the other end of the selection resistor is grounded;

[0014] The identification program is configured such that after the microcontroller is powered on, the identification IO port of the microcontroller connected to the selection resistor is configured in an input mode with a pull-up. When the logic level detected by the identification IO port is high, the selection resistor is not present, and the electric ceramic stove is determined to be a mechanical disc type electric ceramic stove. When the logic level detected by the identification IO port is low, the selection resistor is present, and the electric ceramic stove is determined to be an electronic disc type electric ceramic stove.

[0015] Alternatively, the identification program is configured such that, after the microcontroller is powered on, an identification IO port of the microcontroller connected to the selection resistor is configured in an input mode with a pull-up function. When the logic level detected by the identification IO port is high, the selection resistor is not present, and the electric ceramic cooktop is determined to be an electronic disc type electric ceramic cooktop. When the logic level detected by the identification IO port is low, the selection resistor is present, and the electric ceramic cooktop is determined to be a mechanical disc type electric ceramic cooktop.

[0016] Furthermore, the resistance of the selection resistor is greater than 0K and less than or equal to 100K.

[0017] Furthermore, the identified IO port is any IO port on the single chip microcomputer.

[0018] Furthermore, the model of the single chip microcomputer is BF7615BM28.

[0019] Furthermore, the selection resistor is a pull-down resistor.

[0020] Furthermore, the identification element is mounted on the control board, and the identification element is electrically connected to the control board.

[0021] The beneficial effects of the present invention are as follows:

[0022] The present invention uses an identification element (i.e., a selection resistor) in conjunction with the control board's identification program to automatically determine the type of the cooktop of an induction cooktop. This results in efficient identification, allowing both electronic and mechanical induction cooktops to share a common program. This reduces the number of programs, facilitates program management and maintenance, and reduces program errors. Compared to the prior art, where electronic and mechanical induction cooktops use two different hardware control boards, the present invention uses the same bill of materials for both electronic and mechanical induction cooktops, reducing material coding. The control board is interchangeable between electronic and mechanical induction cooktops, enhancing material compatibility. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0026] See also Figure 1-2 The method for quickly identifying the type of electric ceramic stove hob includes the following steps:

[0027] A. The control panel of the electric ceramic stove is loaded with an electronic disc program for controlling the operation of an electronic disc electric ceramic stove, a mechanical disc program for controlling the operation of a mechanical disc electric ceramic stove, and an identification program for distinguishing between electronic disc electric ceramic stoves and mechanical disc electric ceramic stoves. The control panel can be used to control the operation of either an electronic disc electric ceramic stove or a mechanical disc electric ceramic stove. The mechanical disc program and the electronic disc program can be combined into one program and loaded into the control panel of the electric ceramic stove, facilitating the production of the control panel.

[0028] B. When assembling an electric ceramic stove, electronic disc electric ceramic stoves and mechanical disc electric ceramic stoves are distinguished by whether an identification element is further installed. The identification element is used to connect to the control board. The identification element is installed on the control board and is electrically connected to the control board. When the control board is started, an identification program detects whether the identification element is connected to the control board;

[0029] The present invention distinguishes between an electronic disc-type electric ceramic stove and a mechanical disc-type electric ceramic stove by checking whether an identification element is connected to a control panel, thereby enabling rapid identification of the type of the electric ceramic stove stove plate.

[0030] In one embodiment of the present invention, the identification element is a selection resistor, the selection resistor is a pull-down resistor, the single-chip microcomputer of the control board is connected to one end of the selection resistor, and the other end of the selection resistor is grounded;

[0031] When the control panel detects the presence of the identification element, i.e., the ceramic stove is installed with the identification element, the control panel determines that the ceramic stove is an electronic disc type ceramic stove, and the control panel executes the electronic disc program. When the control panel does not detect the identification element, i.e., the ceramic stove is not installed with the identification element, the control panel determines that the ceramic stove is a mechanical disc type ceramic stove, and the control panel executes the mechanical disc program.

[0032] Specifically, the identification program is configured such that after the microcontroller is powered on, the identification IO port of the microcontroller connected to the selection resistor is configured in an input mode with a pull-up. When the logic level detected by the identification IO port is high, the selection resistor is not present, i.e., the ceramic hob is not installed with the identification element, and the ceramic hob is determined to be a mechanical disc type. When the logic level detected by the identification IO port is low, the selection resistor is present, i.e., the ceramic hob is installed with the identification element, and the ceramic hob is determined to be an electronic disc type, thereby achieving rapid identification of the ceramic hob type.

[0033] Alternatively, when the control panel detects the presence of the identification element, i.e., the ceramic stove is installed with the identification element, the control panel determines that the ceramic stove is a mechanical disc type ceramic stove, and the control panel executes the mechanical disc program. When the control panel does not detect the identification element, i.e., the ceramic stove is not installed with the identification element, the control panel determines that the ceramic stove is an electronic disc type ceramic stove, and the control panel executes the electronic disc program.

[0034] Specifically, the identification program is configured such that after the microcontroller is powered on, the identification IO port of the microcontroller connected to the selection resistor is configured in a pull-up input mode. When the logic level detected by the identification IO port is high, the selection resistor is not present, i.e., the ceramic cooktop is not installed with the identification element, and the ceramic cooktop is determined to be an electronic disc type. When the logic level detected by the identification IO port is low, the selection resistor is present, i.e., the ceramic cooktop is installed with the identification element, and the ceramic cooktop is determined to be a mechanical disc type, thereby achieving rapid identification of the ceramic cooktop type.

[0035] The present invention uses an identification element (i.e., a selection resistor) in conjunction with a control board's identification program to automatically determine the type of the cooktop of an electric ceramic cooktop. This circuit is simple and provides efficient identification. Both electronic and mechanical cooktops can share a common program, which reduces the number of programs, facilitates program management and maintenance, and reduces program error rates.

[0036] Compared to the prior art, where electronic and mechanical disc-type ceramic stoves use two different control boards, the control boards of the present invention have the same bill of materials, reducing material coding. The control boards are interchangeable between electronic and mechanical disc-type ceramic stoves, demonstrating strong material compatibility.

[0037] In one embodiment of the present invention, the resistance of the resistor is selected to be greater than 0K and less than or equal to 100K. In this embodiment, Figure 1 As shown, the resistor RS is a selected resistor, and the resistance of the selected resistor is 1K.

[0038] In one embodiment of the present invention, the identified IO port is any IO port on the single chip microcomputer. In this embodiment, the identified IO port is the IO port 15 of the single chip microcomputer.

[0039] In one embodiment of the present invention, the model of the single chip microcomputer is BF7615BM28. Of course, the single chip microcomputer may also adopt other models.

[0040] The above is a preferred embodiment of the present invention, which shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention as claimed, which is defined by the appended claims and their equivalents.
