Abstract
The utility model relates to a bimetal temperature protection controller belonging to the technical field of temperature control for electric heating devices. The product comprises two metal temperature sensing sheets. One end of each of the temperature sensing sheets is fixed on an insulator, and a touch board and a spring sheet which are mutually insulated from each other are arranged on the insulator. A first contact and a second contact are respectively fixed on the extending ends of the touch board and the spring sheet in corresponding positions, and the first contact and the second contact are electrically connected with the extending ends of the touch board and the spring sheet. The extending end of the temperature sensing sheet is isolated from the extending end of the spring sheet by insulating particles. The utility model makes the improvement that two conductive ring terminals which are mutually insulated from each other are arranged on the insulator, one of the ring terminals is in touch connection with the touch board, and a bayonet structure for arranging a fuse is formed by the extending ends of the ring terminals. The bimetal temperature protection controller has the advantages of simple installation, low manufacture cost, small volume, high sensitivity, good shock resistance, big contact capacity, etc. The bimetal temperature protection controller can be broadly used for fittings products requiring temperature control for household electric appliances, such as fan heaters, thermal fins, ovens, toasters, pizza machines, frying pans, etc.
Description
Technical field
The utility model relates to a kind of controller, and especially a kind of bi-metal temperature protection controller belongs to electrothermal device temperature control technology field.
Background technology
Understand according to the applicant, the fuse that is applied to thermosistor on industrial iron, warm-air drier, oily fourth, baking box, toaster, Piza machine, deep fryer and so on the electric heating appliance at present is installed in the circuit of complete machine.This fuse installing structure is installed incorrect or electric heating appliance temperature when too high running into; though also can cut off the electric heating appliance load; guarantee the safe in utilization of electric heating appliance; but not only take material during its mounting cost, cost is higher; and can not directly experience the temperature of thermosistor contact, therefore be unfavorable for the protection of thermosistor.
The utility model content
The purpose of this utility model is: at the defective of above-mentioned prior art existence; propose a kind ofly can experience the thermosistor contact temperature; and bi-metal temperature easy for installation is protected controller, thereby helps the protection of thermosistor, guarantees the safe in utilization of electric heating appliance.
In order to reach above purpose; bi-metal temperature protection controller of the present utility model comprises the thermometal thermal sensitive piece; one end of described thermal sensitive piece is fixed on the insulator; the contact plate and the shell fragment that are mounted with mutually insulated also are housed on the described insulator; fixing respectively first contact and second contact that is electrically connected with it of the correspondence position of described contact plate and shell fragment external part; isolate by insulating particle between the external part of described thermal sensitive piece and the shell fragment external part; its improvements are: the two conductor wire ears that insulate mutually also are installed on the described insulator; one of described two line ears are connected with the contact plate contact, and the external part of two line ears forms the bayonet arrangement of settling protective tube.
Like this; drive shell fragment in original deformation and control two contact break-makes by thermal sensitive piece; thereby on the basis of regulation and control electrical heating temperature; owing to not only make protective tube and two contacts form series circuit, and, therefore can directly experience the temperature of contact owing to settle the line ear of protective tube directly to be connected with the contact plate contact of fixed contact; thereby when contact temperature is too high; in time cut off circuit, the protection temperature detector is guaranteed the safe in utilization of electrical heated appliance.This bi-metal temperature protection controller simple installation; reduced production cost; and have advantages such as volume is little, highly sensitive, vibration strength is good, contact capacity is big; long service life, not fragile, reliability is high, can be widely used in the household electrical appliances accessory product that warm-air drier, oily fourth, baking box, toaster, Piza machine, deep fryer etc. need temperature control.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
Embodiment
Embodiment one
The bi-metal temperature protection controller of present embodiment as shown in Figure 1; thermometal thermal sensitive piece 08; one end of contact plate 11 and combination shell fragment 06 is separately fixed on the insulator 12; each other by porcelain logical 13; 14 insulation of porcelain ring are isolated. fixing respectively first silver contact 10 and second silver contact that is electrically connected with it of correspondence position of contact plate 11 and combination shell fragment 06 external part. and the porcelain grain 07 by insulation between the outermost end 09 of the external part of thermal sensitive piece 08 and combination shell fragment 06 is isolated; the two-phase intercommunication also is installed on the insulator 12 crosses the conductor wire ear 16 of mica sheet 17 insulation; one of two line ears are connected with contact plate 11 contacts; the external part of two line ears forms the bayonet arrangement of settling protective tube 18. in addition; also fixedly connected with top board 01 on the combination shell fragment 06 by porcelain ring 15; the external part of this top board is by meson 04 fixed copper mandrel 03; temperature adjustment screw 02 is housed in the internal thread hole of this copper mandrel; this temperature adjustment screw 02 and combination are separated with that the temperature adjustment insulating part that is supported on the top board---porcelain grain 05. like this between the shell fragment 06; can be by regulating the temperature adjustment screw; adjust the combination shell fragment and press to the pretightning force of thermal sensitive piece, thereby reach the purpose of regulating temperature controller control temperature.
Present embodiment is because on the basis of original KS thermosistor; set up protective tube; therefore can widely directly should be on various electrical heated appliances; with other control circuit interlock; to gas; the temperature of steam or liquid realizes on-off control: promptly in installation and use; in case of installing incorrect or the electric heating appliance temperature is too high; this bi-metal temperature protection controller not only can be controlled temperature by thermal sensitive piece; and can rely on the protective tube of subsidiary fuse to experience environment; especially the temperature of contact; when temperature reaches the melting point of fusible alloy; fusible alloy fusing in the protective tube, under the effect of special resin, the alloy of fusing shrinks balling-up rapidly; thereby cut-out electric current; the load of electric heating appliance is cut off, guaranteed the safe in utilization of electric heating appliance, effectively motor and fire failure generation are burnt in prevention.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
