Description

Technical Field

[0001] The invention relates to the field of temperature controllers, and in particular to a dual-path compensation temperature control temperature controller with a switch function. Background Art

[0002] Currently, there are two generations of such thermostats (bimetallic adjustable thermostats) on the market. The first generation is the bimetallic working environment temperature sensing thermostat, and the second generation is the living environment heating wire simulating working temperature compensation thermostat.

[0003] The first generation is a temperature-sensitive bimetal placed directly in the control environment. The thermostat is energized, the working environment load is energized, and the working environment temperature begins to rise. When the bimetal deforms as the working environment rises, the switch is controlled to cut off the power, so that the load loses power and the working environment temperature no longer rises. Because the equipment is located in the living environment, there is heat exchange between the working environment and the living environment, so the temperature of the working environment decreases over time, and the thermostat bimetal also recovers as the temperature decreases, so that the switch is turned on again, the load is energized, and the cycle continues to control the working environment temperature within the required range. As the required working environment contains more substances (flammable items, contaminated items, the product's own temperature resistance and other restrictions, the switch in the working environment will produce arcs and sparks, which urgently need to be resolved for equipment safety. Contaminated items will contaminate the switch contacts, limit the switch overload capacity, and affect normal operation). Because the first generation of products could not meet the needs, the second generation was produced.

[0004] The second generation is a temperature-sensitive dual-metal placed in the living environment and a heating wire is energized to generate heat, providing the dual-metal with the heat (temperature) required for operation (disconnection) to cause the switch to operate, simulate the temperature change of the working environment, control the on and off of the load, and achieve temperature control of the working environment. The second generation of products effectively solves the defects of the first generation of products (flammable materials, pollution, and high temperature resistance). It is a qualitative leap over the first generation, but it also has its own defects, simulating the temperature of the working environment (it has high requirements for the living environment state. When the living environment temperature changes slightly, the simulated temperature changes, which amplifies the peak value of the working environment, and the temperature control temperature deviation is large, and it cannot accurately control the working environment with relatively high requirements).

[0005] Because the first and second generation products are thermostats that directly control single-channel loads, with the development of urbanization and the accelerated pace of life, high-power and fast-moving products have been bred. The existing thermostats have high temperature surges and large temperature ranges when controlling the working environment, which has certain disadvantages and does not meet people's usage requirements.

[0025] The first contacts 7 are arranged on the upper outer surface of the second movable contact piece 4 near the first ceramic rice 6 and on the lower outer surface of the first fixed contact piece 5 away from the thermostat body 1, and the two groups of first contacts 7 are in contact with each other.

[0026] The compensation load component includes a third moving contact piece 8, a second fixed contact piece 9, a double gold sheet 10 and a second ceramic rice 11. One end of the third moving contact piece 8 is arranged between the second wiring piece and the fourth magnetic ring, one end of the second fixed contact piece 9 is arranged between the fourth magnetic ring and the fifth magnetic ring, one end of the double gold sheet 10 is arranged between the fifth magnetic ring and the third wiring piece, the second ceramic rice 11 is arranged between the third moving contact piece 8 and the double gold sheet 10, and the second ceramic rice 11 is located at the end of the third moving contact piece 8 and the double gold sheet 10 away from the thermostat body 1, and a compensation wire 15 is arranged at the lower end of the double gold sheet 10.

[0027] The lower outer surface of the third movable contact piece 8 is close to the thermostat body 1 and the upper outer surface of the second fixed contact piece 9 is away from the thermostat body 1. The two groups of second contacts 12 are fitted together.

[0028] The temperature regulating device comprises an adjusting rod 13 and a ceramic column 14 . The ceramic column 14 is arranged at the lower end of the adjusting rod 13 , and the ceramic column 14 is movably mounted on the mounting bracket 2 .

[0029] The outer surface of the ceramic column 14 is provided with a thread, and the lower end of the ceramic column 14 passes through the first moving contact piece 3, the second moving contact piece 4 and the first fixed contact piece 5 and is connected to the upper outer surface of the third moving contact piece 8. The thread on the outer surface of the ceramic column 14 fits with the upper end surface of the first moving contact piece 3.

[0030] It should be noted that the present invention is a dual-channel compensation temperature control thermostat with switch function. The heating load component and the compensation load component are respectively connected to the working heating load and the temperature compensation load of the equipment through the wiring piece. The temperature compensation load power is less than the working heating load power. When in use, the two-channel load contact is connected, the working heating load and the temperature compensation load are energized, and the equipment works normally. When working, the compensation wire 15 heats the simulated working temperature, and the compensation wire 15 heats the double gold sheet 10. When the temperature reaches the set value, the double gold sheet 10 is deformed, so that the two groups of second contacts 12 are disconnected, and the temperature compensation load The load and the compensation wire 15 are powered off, the working heating load works normally, the equipment temperature is maintained, and a temporary thermal balance is achieved inside the equipment. After a period of time, the thermal balance is broken, and the double gold sheet 10 recovers its shape after heat dissipation, the second contact 12 is closed, the temperature compensation load and the compensation wire 15 are powered on, the temperature compensation load and the working heating load are heated together, and the compensation wire 15 heats the double gold sheet 10 again. When the temperature reaches the set value again, the double gold sheet 10 is deformed, so that the two groups of second contacts 12 are disconnected, the temperature compensation load is powered off, the temperature drops, and the reciprocating cycle is repeated, so that the temperature is controlled within a certain range;

[0031] When in use, the working heating load power is always working, so that the temperature change of the working environment is small during the process from disconnection to recovery of the double gold sheet 10;

[0032] When the temperature adjustment device is used, the adjustment rod 13 is rotated, and the adjustment rod 13 drives the porcelain column 14 to descend, thereby changing the height of the third movable contact piece 8. The lower the third movable contact piece 8 is, the smaller the displacement required for the contact to be disconnected is, and thus the temperature is lower during temperature control;

[0033] When the adjusting rod 13 rotates, the thread on the outer surface of the adjusting rod 13 contacts the first moving contact piece 3, driving the first moving contact piece 3 to descend, so that the first contact 7 is fitted. When the adjusting rod 13 rotates, the ceramic column 14 rotates synchronously, and the ceramic column 14 drives the third moving contact piece 8 to descend, so that the second contact 12 is fitted. The adjusting rod 13 controls the fitting of the first contact 7 and the second contact 12 in the early stage of rotation, and continues to rotate after fitting to change the position of the third moving contact piece 8, so as to adjust the temperature of the thermostat. When the thermostat is not working, the two groups of first contacts 7 and the two groups of second contacts 12 are disconnected.

[0034] By setting up the heating load component and the compensation load component, the two groups of loads cooperate with each other, the active power of the equipment load is improved, and the temperature surge generated by the power temperature compensation load is small, which can reduce the insulation cost of the equipment and improve the temperature control accuracy of the thermostat. Changes in the living environment temperature can only cause changes in the power temperature compensation part, and the changes produced are only slight changes in the temperature difference. The temperature control time is shorter and the efficiency is higher, reducing the impact of changes in the living environment temperature on the temperature control accuracy of the thermostat. Moreover, the entire dual-channel compensation temperature control thermostat with switch function is easy to operate, and the use effect is better than the traditional method, which meets people's use requirements and is more practical.

[0035] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
