Description
The utility model relates to a kind of temperature controller, the electrical heating temperature sensing controller that particularly a kind of constant temperature scope is adjustable.
In the conventional electric heating temperature controller, be to make sensing control mostly with a bimetallic strip, its constant temperature scope is nonadjustable.Chinese patent CN2305605Y has constant temperature scope adjustable function, but influenced by its thermometric mode, make troubles to installation, and the temperature adjustment process is complicated.
The purpose of this utility model is that a kind of constant temperature scope that above-mentioned the deficiencies in the prior art provide is adjustable in order to overcome, reliable operation, temperature sensing controller easy to install and use.
For achieving the above object, the technical solution of the utility model is by front panel, side cover plate, biography temperature back shroud, and mounting is formed with the thermostatic control mechanism that is contained in inside, overtemperature mechanism and thermoregulative mechanism.Thermoregulative mechanism is by being embedded in the nut in the mounting and being contained in its inner temperature adjustment screw rod and member read in the accent of upper end, and the Thermal Control Element of lower end constitutes.
Thermal Control Element is that two ends are to bending to 90 ° of " Jiong " shapes in the same way, end in contact under its upper surface middle part and the temperature adjustment screw rod, one side is gone to the bottom, and the oblong aperture that is placed on the warm back shroud of mounting upper and lower end insertion biography is interior, the upper surface contacts with mounting, and the other end contacts with the thermostatic element centre of constant temperature mechanism.
Above-mentioned Thermal Control Element also can be the turning shape that curves 90 °, end in contact under its upper surface middle part and the temperature adjustment screw rod, and an end is packed on the mounting, and the other end contacts with the thermostatic element centre.
Accent is read member and is constituted by tightening up the indication turn-knob that is contained in temperature adjustment screw rod upper end and being mated fixing graduated arc or the ring-type index dial of installing.
Thermostatic control mechanism and overtemperature prote mechanism are prior aries.Thermostatic control mechanism is by being contained in the garden post that is slidingly connected in the mounting, garden fore-set, thermostatic element that the lower end joins, and the upper end terminal screw, the constant temperature moving contact assembly, the constant temperature stationary contact assembly that are riveted on the mounting are formed.Overtemperature prote mechanism is by being contained in the cruciform fore-set that is slidingly connected in the mounting, the transmission garden post of both sides, and the overtemperature element that is riveted on interior overtemperature moving contact assembly of mounting and stationary contact assembly and upper end terminal screw, lower end constitutes.Thermostatic element is respectively to be processed into the different bimetallic strip of thickness with material through different process with the overtemperature element, and its two ends are installed on the mounting.K1 is made of constant temperature moving contact assembly and constant temperature stationary contact assembly.K2-1, K2-2 by overtemperature stationary contact assembly respectively and two overtemperature moving contact assemblies constitute.
Accompanying drawing drawing of the present utility model is described as follows:
Fig. 1 is a front view of the present utility model
Fig. 2 is the topology view that Fig. 1 removes front panel
Fig. 3 is that the A-A of Fig. 2 analyses and observe and changes 90 ° structural drawing clockwise
Fig. 4 is the rear view that passes warm back shroud
Fig. 5 is the B-B cut-open view of Fig. 4
Fig. 6 is an electrical schematic diagram of the present utility model.
The utility model is described in further detail below in conjunction with embodiment (accompanying drawing).
As Fig. 1-shown in Figure 6, front panel 8, side plate 9 to be housed around the mounting 6, to pass warm back shroud 5, be equipped with rivet 24 fixing thermostatic control mechanism, overtemperature prote mechanism and thermoregulative mechanism inside.The nut 13 of thermoregulative mechanism and the temperature adjustment screw rod 10 of interior dress are embedded in the mounting 6, and its upper end is the temperature adjustment indication turn-knob 11 that tightens up and the fixing graduated arc of installing 14 that matches, and there is " Jiong " shape Thermal Control Element 2 lower end.Thermal Control Element 2 one ends insert in the pilot hole 25 that passes warm back shroud groove 26, and the other end contacts with the centre of thermostatic element 3.The garden post 7 of thermostatic control mechanism is contained in the mounting 6 and is slidingly connected, and its lower end joins successively garden fore-set 4, thermostatic element 3, and the upper end contacts successively with constant temperature moving contact assembly 22, constant temperature stationary contact assembly 23, and is provided with terminal screw 18.The cruciform fore-set 16 of overtemperature prote mechanism is contained in the mounting and can slides up and down, and contacts with the knob 17 that resets above it, and the lower end is contacted overtemperature element 1.Transmission garden post 12,15 and parallel its corresponding both sides that are contained in of cruciform fore-set, lower end and cruciform fore-set cross bar two ends join, and the upper end is contacted successively to be had overtemperature moving contact assembly 20,21 and plays gentle and quiet contact assembly 19, and is provided with terminal screw 18.
Thermoregulative mechanism, thermostatic control mechanism and overtemperature prote mechanism are mutual coupling, interactional organic whole.When connecting external power supply, electric current forms path through K1, heating tube 28, K2-1, K2-2,28 pairs of heated body heat temperature raisings of heating tube, and the biography temperature aluminium matter back shroud 5 that is close to the heated body surface is passed to thermostatic element 3 and overtemperature element 1 with heat.Reach on the predefined temperature range in limited time in temperature,, promote garden fore-set 4, garden post 7 successively, make the thread off outage and stop to heat of constant temperature moving contact assembly 22 and constant temperature stationary contact assembly 23, and make temperature begin to descend because thermostatic element 3 temperature distortions are arched upward.Drop under the design temperature scope in limited time in temperature, because thermostatic element resets with the temperature distortion that descends, make constant temperature moving contact assembly 22 and stationary contact assembly 23 hasps connect circuit, the 28 fork beginnings of heating tube heat to heated body.The continuous repetition of said process is to reach the thermostatic control purpose.When thermostatic control mechanism breaks down because of artificial or non-artificial reason; temperature surpasses on the constant temperature prescribes a time limit; 1 distortion of overtemperature element is arched upward; promoting the cruciform fore-set rises; make toplap temperature moving contact assembly 20,21 on the transmission garden post 12,15; itself and overtemperature stationary contact assembly 19 are threaded off cut off the power supply and stop to heat, to reach the overtemperature prote effect.At this moment, even temperature drops under the constant temperature in limited time, K2-1, K2-2 can not connect automatically, have only manually to press the knob 17 that resets and just can make it reclose circuit, work on.Recessed post 27 is to be stamped to form passing on the warm back shroud, in order to fixedly thermostatic element and overtemperature element.
Compared with prior art novel to have the constant temperature scope adjustable, safe and reliable in this use, the side of installing and using Just with the simple advantage of manufacturing process.
