Electric iron & Electric oven Adjustable bimetal thermostat technical parameters

1, the adjustable bimetal thermostat structure
Adjustable thermostat including large body bracket, Also includes the cam temperature adjustment shaft, positioning shrapnel, large body shell, porcelain column, Large body piece riveted in the big piece of film and large pieces of stent composition limit cavity. The cam temperature adjustment shaft is disposed above the limit cavity and downwardly through the large body case, The bottom of which is arranged in the limit cavity. One end of the ceramic column is connected to the bottom of the cam temperature regulating shaft, The other end down through the large body stent,
The positioning spring is fixed to the side wall of the restriction cavity. When the temperature drops to the reset temperature setting, Bimetallic discs quickly restored to its original state. So that the contact closed or disconnected, The purpose of switching on or off the circuit, Thereby controlling the circuit.

2, the adjustable bimetal thermostat action principle
Adjustable thermostat is a fixed temperature after the bimetallic wafer as a heat sensitive components,
When the main pieces of the product when the temperature increases the heat generated by the transfer to the bimetallic disc. When the action temperature setting is reached, Through the role of institutions to make contacts open or closed;
When the temperature drops to the reset temperature setting, Bimetallic discs quickly restored to its original state. So that the contact closed or disconnected, The purpose of switching on or off the circuit, Thereby controlling the circuit.

3, adjustable bimetal thermostat work
Adjustable iron bimetal thermostat is how the thermostat it? Credit also attributed to the use of bimetal automatic temperature control switch. Bimetallic is the same length and width of copper and iron sheet tightly riveting together made of. When heated, due to the expansion of copper than iron sheet, bimetal to the iron side of the bend. The higher the temperature, the more obvious bending. At normal temperatures, the bimetal tip contacts are in contact with the contacts on the elastic copper sheet.
When the iron head is connected to the power source, Current through the contact with the copper, bimetal, flowing through the heating wire, heating wire heat and heat transfer to the bottom of the metal floor, iron. People can use the floor heating of ironing clothes. As the energization time increases, When the temperature of the bottom plate is raised to the set temperature, The bimetal, fixed to the base plate, is heated and bent downwards. The contacts on the top of the bimetal thermostat are separated from the contacts on the elastic copper sheet, The circuit is then disconnected. Then the temperature of the bottom plate is no longer increased, Due to the heat dissipation of the bottom plate;

Bimetallic deformation is gradually restored. When the temperature drops to a certain value, Bimetal and elastic copper and re-contact. The circuit is switched on again, The temperature of the soleplate begins to rise again. In this way, when the temperature is higher than the required temperature circuit is broken. When the temperature is lower than the required temperature when the circuit is connected, The temperature can be maintained within a certain range.
So, how to make the irons have different temperatures? When you put the thermostat button up, The upper and lower contacts move up. The bimetal can be separated only by a slight downward bending. Obviously this time the floor temperature is low, The bimetal can control the temperature of the soleplate at a lower temperature. When you turn the thermostat button down, the upper and lower contacts with the next move, Bimetal must be bent to a greater extent, in order to contact separation. Obviously this time the temperature of the bottom plate is higher, The bimetal can control the temperature of the soleplate at a higher temperature. So that it can adapt to the different requirements of the fabric temperature.

4, adjustable bimetal thermostat purposes:Reliable product simply, do not pull the arc, long life, radio interference is small, accurate control of temperature. Widely used in electric iron, electric oven, frying pan, warm milk, heat wave oven, light oven, electric pressure cooker, rice cooker temperature control, temperature control, constant temperature use.

5, adjustable bimetal thermostat technical parameters:
1. Electrical parameters: 10A 250V ~; 15A 125V ~
2. Operating temperature range: 0℃ ~ 300℃ optional, operating temperature tolerance: ± 5%
3. Normal electrical strength: 2000V ~ 1min no breakdown, no flashover
4. Contact resistance: <50mΩ, insulation resistance: > 500MΩ
5. Service life: TUV / CQC: 35000 cycles, UL: 100, 000 cycles
6. Temperature adjustment axis rotation angle: 150 ℃, 180 ℃, 210 ℃, 250 ℃, 270 ℃, 300 ℃, 310 ℃


6, adjustable bimetal thermostat installation instructions:
1. High-temperature shaft size and its rotation angle can be set according to customer demand
2. Thermostat off temperature and its characteristic curve according to the customer finished and temperature control match test
3. This product can be designed with the induction current to achieve the purpose of temperature control, And can greatly reduce the temperature amplitude, Remote temperature control, Thermal compensation
4. Terminal size and direction of a variety of options can be arbitrary with the customer
5. To facilitate the installation of the thermostat, Temperature control can also rivet a fixed mounting block (piece), But also has a heat transfer function of the role.

7, adjustable bimetal thermostat Note:
1. Installation of bimetal thermostat ceramic, bimetallic and other physical conditions should not be the role of external forces remain intact.
2. Connect to the bimetal thermostat terminals of the wire: 5A is 0. 5 ~ 1mm2; 10A to 0. 75 ~ 1. 5mm2;
3. If the customer needs to adjust the temperature set value, adjustable bimetal thermostat screw within the screw, Counterclockwise rotation, The temperature setting increases, Conversely reduced.
4. With contact temperature-type installation, bimetal thermostat metal cover plane should be completely close to the control surface of the installation.
5. To ensure that the temperature effect, and the surface temperature of the appliance coated with thermal paste.
6. Installation can not be bimetal thermostat metal surface at the top of crushing, Loose or deformed, So as not to affect the function and precision.
7. Do not allow liquid to penetrate the bimetal thermostat or excessive force inside the shell to crack.
8. Shall not arbitrarily change the shape of the external terminal, So as not to affect the electrical reliability, And have insulation protection measures, To prevent leakage, To ensure the use of security.
