Description

A kind of temperature controller

The utility model belongs to the technical field of temperature controller, relates to a kind of electric heating appliance that is used for, when temperature is too high, and can be with the temperature controller of circuitry cuts.

Usually, all adopt temperature controller and Thermal Cutoffs as control and safety guard in the electric heating appliance, wherein, the structure of temperature controller mainly comprises adjuster bar 1, carriage 2, insulated ring 3, movable contact spring 4, static contact 5 and connection terminal 6 shown in Fig. 4,5.When the temperature controller environment temperature raise above setting value, movable contact spring 4 can separate with static contact 5 under heat effect in the temperature controller.General temperature controller and Thermal Cutoffs wiring mode have two kinds: a kind of be a end with Thermal Cutoffs by lead or directly be welded on the connection terminal 6 of temperature controller unsettledly, when temperature controller loses function, Thermal Cutoffs is worked by radiation; Another kind is to add insulating coating on Thermal Cutoffs, places calandria, when temperature controller loses function, by heat conduction Thermal Cutoffs is worked.But in the such scheme, first kind is by radiation Thermal Cutoffs to be worked, and pretends and uses the time luffing big, and reliability is relatively poor; Second kind is by heat conduction Thermal Cutoffs to be worked, and reliability is better, and it is many to process passage, the cost height.

The purpose of this utility model is to provide a kind of temperature controller, and it is reliable that this temperature controller has action time, simple installation, the effect that cost is low.

For reaching above-mentioned purpose, solution of the present utility model is: temperature controller mainly comprises adjuster bar, carriage, insulated ring, movable contact spring, static contact and connection terminal; Set up one on the connection terminal and connect shell fragment, connect between shell fragment and the connection terminal and be connected by the hot melt alloy material.

Above-mentioned connection shell fragment is fixed on the temperature controller by insulating base.

After adopting said structure, have the effect of Thermal Cutoffs with the hot melt alloy material that is connected shell fragment, can equivalence be considered as the utility model temperature controller and Thermal Cutoffs integrator because of being used to connect connection terminal.The user only needs temperature controller is installed in use, and the hot melt alloy material with Thermal Cutoffs effect has been set directly on the temperature controller, does not need user installation, simplifies action thereby reached, cost-effective effect.In addition, the Temperature protection effect of hot melt alloy material is to realize by heat conduction, because the residing stationkeeping of hot melt alloy material, and hot melt alloy material fluxing temperature is stable, has guaranteed that the control of insurance temperature is reliable.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is the utility model vertical view;

Fig. 2 is the utility model front elevation;

Fig. 3 is the utility model side view;

Fig. 4 commonly uses the product vertical view;

Fig. 5 commonly uses the product side view.

See also Fig. 1-3, visible present embodiment temperature controller mainly comprises adjuster bar 1, carriage 2, insulated ring 3, movable contact spring 4, static contact 5 and connection terminal 6, and mutual alignment between each member and connecting relation are as shown in the figure.The utility model key is: set up one on the connection terminal 6 and connect shell fragment 7, connecting shell fragment 7 is connected with connection terminal 6 by hot melt alloy material 8, and be fixed on the top of temperature controller connection terminal 6 by insulating base 9, though and having added an insulating base 9 in this temperature controller, whole height is constant.Thus, electric current flows into from connecting shell fragment 7 one ends, arrives static contact 5 through hot melt alloy material 8 and connection terminal 6, flows out through movable contact spring 4 to another connection terminal 6 again.

When environment temperature raises, temperature controller movable contact spring 4 will disconnect because of being heated with quiet moving plate, thereby cut off circuit.If temperature controller is malfunctioning, heat can raise hot melt alloy material 8 temperature by connection terminal 6 because of conduction, and fusing, thereby cuts off circuit, plays the effect of double insurance.

Claims (2)
