Problems solved by technology

[0002] With the development of technology, many cooking devices need power supply; so, if there are multiple cooking devices in the kitchen, these cooking devices all have their own power supply lines connected to the socket. On the other hand, many wires require multiple sockets, and when the wires are old or damaged, it is easy to cause safety accidents due to leakage

example 1

[0133] Such as Figure 5 As shown, this example provides an electrical device 1 , which can be a full-surface intelligent electromagnetic cooktop. This electrical equipment includes:

[0134] The bearing surface 11 on the surface of the cooktop;

[0135] Integrated modules 4 for independent heating or power transmission; the integrated modules form a matrix layout.

[0136] A hand-held mobile phone 2 ; other digital or electronic equipment or devices 3 ; cooking equipment such as an iron pan 5 are arranged on the carrying surface 11 .

[0137] Among them, all independent heating or power transmission modules are numbered according to certain rules as shown in the figure below. When the cooktop is powered on, the cooktop can automatically detect and identify the type and / or area of ​​the load on the cooktop. Such as Figure 6 As shown, the detection identifies that there is a pot above the integrated modules 5-3, 5-4, 6-3, 6-4, and it is a pot.

[0138] The integrated modu...

example 2

[0160] This example provides a detection spool that can be used as figure 2 shown, including:

[0161] power line, corresponding to figure 2 thick line in

[0162] signal lines, corresponding to figure 2 in the thin line.

[0163] The power line is used for power control; the signal line is used for various sensor detection; in this way, there is no need to use single-pole double-throw switches or relays; the type, position and area occupied by the load on the load-bearing surface can be dynamically detected in real time. signal; the detection power is small, and the change of the load position can be determined in real time; the equivalent inductance and resistance value can be calculated while detecting the position, which can be fed back to the control circuit to make heating or power transmission more efficient; various power combination designs can be carried out Wait.

Abstract

The embodiment of the invention discloses a detection module and electrical equipment. The detection module comprises a detection wire coil which can be mutually inducted with a load located in a predetermined bearing area to generate different impedances, and a detection circuit which is connected with the detection wire coil and has working signals with different signal values when the impedanceis different. The working signals are used for determining whether a load exists or not and / or determining the load type of the load.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a detection module and electrical equipment. Background technique [0002] With the development of technology, many cooking devices need power supply; so, if there are multiple cooking devices in the kitchen, these cooking devices all have their own power supply lines connected to the socket. On the other hand, many wires require multiple sockets, and when the wires are old or damaged, it is easy to cause safety accidents due to leakage. Contents of the invention [0003] In view of this, the embodiment of the present invention expects to provide a detection module and electrical equipment. [0004] Technical scheme of the present invention is realized like this: [0005] A detection module, comprising: [0006] Detecting the reel, capable of mutual inductance with the load located in the predetermined carrying area to generate different impedances; [0007] T...
