Description

Technical Field

[0001] The invention belongs to a household electric heater and its temperature detection and control, and relates to an improvement of a temperature detection method for an electric ceramic stove. Specifically, it is a method for detecting the temperature of an electric ceramic stove and a heating area of ​​a stove surface or a vessel on the heating area and controlling the temperature according to the temperature.

[0002] Prior art The electric ceramic stove emits heat from the heating plate and heats the container in the form of radiation. There is no need to install heating elements in the container. It is suitable for heating non-specific containers, including containers of different materials. Therefore, it is widely popular in people's homes.

[0003] However, the heating of the vessel is achieved only by contact with the surface of the electric ceramic stove, and there is no connection between the two through other devices, which makes it difficult to detect the temperature of the vessel. Even if the temperature of the vessel can be detected, there is still the problem of how to transmit the signal to the controller in the electric ceramic stove and how to control it according to these signals.

[0004] The object of the present invention is to provide an electric ceramic stove and a temperature detection and control method thereof. According to this method, the temperature of the electric ceramic stove during the water boiling process can be detected, and when the water boils or the kettle is empty, the heating plate can be powered off.

[0005] The temperature detection method of the electric ceramic stove of the present invention is realized by the following scheme: A method for detecting the temperature of an electric ceramic stove, comprising the following steps: (10) The controller in the electric ceramic stove controls the power supply to the heating plate, so that the heating plate generates heat; (20) Raise the temperature detection assembly from the side of the electric ceramic stove, and point the thermopile at the heating area or the vessel in the heating area to obtain a temperature signal; (30) The temperature signal obtained by the thermopile is transmitted to the controller in the electric ceramic furnace through the temperature detection component.

[0006] Preferably, the above-mentioned method for detecting the temperature of an electric ceramic stove further comprises step (40): (40) Lower the temperature detection component and return it to its original position.

[0007] The obtained method for detecting the temperature of the ceramic stove can detect the temperature of the heating area on the surface of the ceramic stove at any time by the thermopile, or detect the temperature of the container in the heating area at any time, and the temperature detected by the thermopile can be transmitted to the controller in the ceramic stove in real time through the temperature measuring component, and then the controller can perform relevant control according to the temperature.

[0008] The electric ceramic stove control method of the present invention can be implemented by the following first solution: A method for controlling an electric ceramic stove, comprising the following steps: (10) The controller in the electric ceramic stove controls the power supply to the heating plate, so that the heating plate generates heat; (20) Raise the temperature detection component from the side of the electric ceramic stove, and point the thermopile at the heating area to obtain a temperature signal; (30) transmitting the temperature signal obtained by the thermopile to the controller in the electric ceramic furnace through the temperature detection component; (40) The controller compares and judges the temperature signal obtained by the thermopile and performs the following operations: If the temperature obtained by the thermopile exceeds 100 degrees Celsius, it is considered that the electric ceramic stove is in an empty-burning state, and the controller controls the power supply to stop supplying power to the heating plate.

[0009] The electric ceramic stove control method of the present invention can be implemented by the following second solution: A method for controlling an electric ceramic stove, comprising the following steps: (10) The controller in the electric ceramic stove controls the power supply to the heating plate, so that the heating plate generates heat; (20) Raise the temperature detection component from the side of the electric ceramic stove, and point the thermopile at the heating area to obtain a temperature signal; (30) transmitting the temperature signal obtained by the thermopile to the controller in the electric ceramic furnace through the temperature detection component; (40) The controller compares and judges the temperature signal obtained by the thermopile and performs the following operations: If the temperature obtained by the thermopile exceeds 100 degrees Celsius and lasts for more than a certain period of time, it is considered that the electric ceramic stove is in an empty-burning state, and the controller controls the power supply to stop supplying power to the heating plate.

[0010] In this way, in the control method of the electric ceramic stove, whether the first scheme or the second scheme, both can control the empty burning of the kettle, that is, when there is no utensil on the heating area, the temperature detected by the thermopile is the temperature of the surface of the heating area, which will exceed 100 degrees Celsius, and it will be dangerous when there is no utensil placed on it. Therefore, when the temperature exceeds 100 degrees Celsius, or the temperature exceeds 100 degrees Celsius and lasts for more than a certain period of time, at this time, the controller can control the power supply to stop supplying power to the heating plate, thereby obtaining a control method for when the utensil is lifted from the electric ceramic stove and leaves the stove surface and the electric ceramic stove is empty.

[0011] The electric ceramic stove control method of the present invention can be implemented by the following third solution: A method for controlling an electric ceramic stove, comprising the following steps: (10) The controller in the electric ceramic stove controls the power supply to the heating plate, so that the heating plate generates heat; (20) Raise the temperature detection assembly from the side of the electric ceramic stove, and point the thermopile at the vessel in the heating area to obtain a temperature signal; (30) transmitting the temperature signal obtained by the thermopile to the controller in the electric ceramic furnace through the temperature detection component; (40) The controller compares and judges the temperature signal obtained by the thermopile and performs the following operations: If the temperature obtained by the thermopile does not exceed 100 degrees Celsius and the temperature is stable for a certain period of time, it is considered that the water in the vessel is in a boiling state, and the controller controls the power supply to stop supplying power to the heating plate.

[0012] Therefore, the third scheme in the control method of the electric ceramic stove can control the boiling of the vessel during the boiling process. When a vessel is placed on the heating area to boil water, the water in the vessel continuously absorbs heat from the vessel and its temperature continuously rises, and the temperature of the vessel also rises, but the temperature of the vessel will not exceed 100 degrees Celsius. When the water in the vessel boils, the temperature of the vessel no longer rises and remains stable. At this time, the controller can control the power supply to stop supplying power to the heating plate, thereby obtaining a control method for boiling during the boiling process of the electric ceramic stove.

[0013] The electric ceramic stove control method of the present invention can be implemented by the following fourth solution: A method for controlling an electric ceramic stove, comprising the following steps: (10) The controller in the electric ceramic stove controls the power supply to the heating plate, so that the heating plate generates heat; (20) Raise the temperature detection assembly from the side of the electric ceramic stove, and point the thermopile at the heating area or the vessel in the heating area to obtain a temperature signal; (30) transmitting the temperature signal obtained by the thermopile to the controller in the electric ceramic furnace through the temperature detection component; (40) The controller compares and judges the temperature signal obtained by the thermopile and performs the following operations: If the temperature obtained by the thermopile exceeds 100 degrees Celsius, the electric ceramic stove is considered to be in an empty-burning state, and the controller controls the power supply to stop supplying power to the heating plate; or If the temperature obtained by the thermopile does not exceed 100 degrees Celsius and its temperature remains stable for a certain period of time, it is considered that the water in the vessel is boiling, and the controller controls the power supply to stop supplying power to the heating plate.

[0014] The electric ceramic stove control method of the present invention can be implemented by the following fifth scheme: A method for controlling an electric ceramic stove, comprising the following steps: (10) The controller in the electric ceramic stove controls the power supply to the heating plate, so that the heating plate generates heat; (20) Raise the temperature detection assembly from the side of the electric ceramic stove, and point the thermopile at the heating area or the vessel in the heating area to obtain a temperature signal; (30) transmitting the temperature signal obtained by the thermopile to the controller in the electric ceramic furnace through the temperature detection component; (40) The controller compares and judges the temperature signal obtained by the thermopile and performs the following operations: If the temperature obtained by the thermopile exceeds 100 degrees Celsius, it is considered that the electric ceramic stove is in an empty-burning state, and the controller controls the power supply to stop supplying power to the heating plate, and the process goes to step (60); If the temperature obtained by the thermopile does not exceed 100 degrees Celsius and its temperature is stable within a certain period of time, it is considered that the water in the vessel is in a boiling state, and the controller controls the power supply to stop supplying power to the heating plate, and the process goes to step (60); (50), repeat step (30); (60) Lower the temperature detection component and return it to its original position.

[0015] Thus, in the fourth and fifth schemes of the control method of the electric ceramic stove, when there is no vessel in the heating area, the thermopile is facing the heating area to detect the temperature of the surface of the heating area; when there is a vessel in the heating area, the thermopile is facing the vessel to detect the temperature of the vessel. Therefore, it can control the empty boiling of the kettle and the boiling of water in the vessel. A control method is obtained when a vessel is lifted from the electric ceramic stove and leaves the stove surface and the electric ceramic stove is empty or when water in the vessel boils during the boiling process of the electric ceramic stove.

[0016] The electric ceramic stove of the present invention is realized by the following scheme: An electric ceramic stove, in which a microcrystalline glass, a heating plate, a controller and a power supply are arranged in the stove body, and the controller can control the power supply to supply power to the heating plate. The stove body is also equipped with a driving mechanism, a temperature detection component is installed on the side of the stove body, and a thermopile is installed on the temperature detection component. The driving mechanism can drive the temperature detection component to rise, and the thermopile is facing the heating area of ​​the microcrystalline glass. The temperature signal obtained by the thermopile is transmitted to the controller through the temperature detection component, and the controller controls the power supply to supply power to the heating plate according to the temperature signal provided by the thermopile.

[0017] In this way, the driving mechanism can drive the temperature detecting component to rise, and the thermopile can rise along with the temperature detecting component, and can face the heating area from the side of the furnace body at any time. When a vessel is placed on the heating area, the thermopile faces the vessel from the side of the furnace body. Therefore, the thermopile can detect the temperature of the heating area or the vessel on the heating area. In addition, the thermopile can be lowered back to its original position along with the temperature detecting component to avoid the temperature detecting component being exposed to radiation for a long time, especially when the kettle is empty, the radiation can easily cause damage to the temperature detecting component.

[0018] Preferably, in the above electric ceramic stove solution, the driving mechanism is a reduction motor, a rack is installed on the side of the temperature detection component, the reduction motor cooperates with the rack through an output gear, and the forward and reverse rotation of the reduction motor can control the lifting and lowering of the temperature detection component.

[0019] Preferably, in the above electric ceramic furnace, the temperature detection assembly is raised high enough to allow the thermopile to be higher than the vessel, and the thermopile faces the heating area of ​​the micro-ceramic glass in a manner that forms an acute angle with the vertical downward direction.

[0020] The electric ceramic stove and the temperature detection and control method thereof of the present invention enable the electric ceramic stove itself to detect the temperature of its heating area or the container on the heating area, and transmit the detected temperature signal to the controller, thereby solving the problem of temperature detection and transmission that has always existed in the electric ceramic stove. At the same time, the invention also proposes to control the electric ceramic stove according to the detected temperature, and in the process of boiling water, when the water boils or the kettle is empty, the electric ceramic stove can be automatically powered off to play a protective role.

The reduction motor 4 can move the rack 51 up and down together with the temperature detection component 5 through the rotation of the output gear 41. Therefore, the thermopile 3 can be raised and face the heating area 11 of the microcrystalline glass 1, and the temperature signal obtained by the thermopile 3 can be transmitted to the controller through the temperature detection component 5. The controller can control the power supply to supply power to the heating plate 2 according to the temperature signal provided by the thermopile 3.
