Abstract
The utility model relates to a dual overheat protection device of electromagnetism stove, including installing base (3) between ceramic panels (4) and coil support (5), built-in thermistor (1) and the hot protector (2) that are equipped with side by side of its characterized in that above-mentioned base (3), thermistor (1) and hot protector (2) are hugged closely below ceramic panels (4), and thermistor (1) are connected with main circuit board, and hot protector (2) are connected with the power. The utility model discloses owing to installed two temperature sensing temperature elements of thermal protector and thermistor in the base between ceramic panel and coil support, will make the main circuit disconnection when thermistor detects ceramic panel high temperature, protection circuit components and parts do not receive the harm, when thermal protector detects the panel temperature and surpasss the predetermined value, will directly cut off the power supply, make the electromagnetism stove stop heating to the dual overheat protection of electromagnetism stove has been realized.
Description
Technical field
The utility model is a kind of dual overtemperature protection system, the dual overtemperature protection system of particularly a kind of electromagnetic oven.
Background technology
The general employing of the method for excessive heating protection of existing electromagnetic oven coated silicone grease at silica gel support; then temperature sensor support is worked the bottom surface that withstands on ceramic panel; temperature sensor generally adopts thermistor; thermistor is connected with the main circuit board of electromagnetic oven; when the temperature that detects ceramic panel when thermistor surpasses predetermined value; CPU on the main circuit board of electromagnetic oven can receive the signal of telecommunication; and then handle and cut off circuit transmission; if but above-mentioned thermistor lost efficacy or owing to reasons such as the manufacturing of thermistor are defective; can cause the thermistor temperature-sensitive to lag behind, make that circuitry cuts is untimely may cause electric fire.
The utility model content
The purpose of this utility model is to provide a kind of can prevent effectively that electromagnetic oven is overheated, and the dual overtemperature protection system of safe and reliable electromagnetic oven is to overcome weak point of the prior art.
The dual overtemperature protection system of a kind of electromagnetic oven by this purpose design; comprise the base that is installed between ceramic panel and the coil brace; its architectural feature is to be equiped with in the above-mentioned base thermistor arranged side by side and thermal protector; thermistor and thermal protector are close to below the ceramic panel; thermistor is connected with main circuit board, and thermal protector is connected with power supply.
Above-mentioned base is made by elastomeric material.
The utility model is owing to installed thermal protector and two temperature-sensitive temperature elements of thermistor in the base between ceramic panel and coil brace; when thermistor detects panel temperature main circuit is disconnected; the holding circuit components and parts are without prejudice; when thermal protector detects panel temperature above predetermined value; will directly cut off the electricity supply; make electromagnetic oven stop heating, thereby realized the dual overtemperature protection of electromagnetic oven.
Description of drawings
Fig. 1 is a decomposing schematic representation of the present utility model;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 shows schematic diagram for of the present utility model cuing open.
The specific embodiment
Structural representation of the present utility model as shown in Figure 1, 2, 3; comprise ceramic panel 4 and coil brace 5; coil brace 5 centers are provided with a circular hole 51; base 3 embeds in this circular hole 51; be equiped with thermistor arranged side by side 1 and thermal protector 2 in the base 3; thermistor 1 and thermal protector 2 are close to below the ceramic panel 4, and thermistor 1 is connected with main circuit board, and thermal protector 2 is connected with power supply.Above-mentioned base 3 is made by elastomeric material.
The utility model electromagnetic oven is under "on" position; induction coil produces magnetic field; be placed on the sensed heating of irony pan on the ceramic panel; the heat transferred ceramic panel of pan bottom; two electrodes that are close to the thermal protector below the ceramic panel are being in the normally closed state that closes under general situation; but when thermal protector detects the ceramic panel temperature above predetermined value; two electrodes will expanded by heating and are unclamped; cut off the electricity supply; make electromagnetic oven stop the heating, meanwhile, thermistor also electrical signal transfer to the CPU on the main circuit board; after the CPU judgment processing internal circuit is cut off, reached the purpose of dual overtemperature protection.
Claims (2)
1. the dual overtemperature protection system of an electromagnetic oven; comprise the base (3) that is installed between ceramic panel (4) and the coil brace (5); it is characterized in that being equiped with in the base (3) thermistor arranged side by side (1) and thermal protector (2); thermistor (1) and thermal protector (2) are close to below the ceramic panel (4); thermistor (1) is connected with main circuit board, and thermal protector (2) is connected with power supply.
2. dual overtemperature protection system according to claim 1 is characterized in that above-mentioned base (3) made by elastomeric material.
