Description
636~5~
This invention relates to a temperature-responsive device, such as a temperature regulator or a thermostat, which may be used in particular in domestic appliances, comprising an electrically insulating body, electrical connectors, fixed and movable contact carriers each carrying a switching contact, a heat conductive member, a dished bimetallic disc, and means for transmitting movement of the disc to the movable contact carrier.
Devices of this type are known in the form of individual thermostats, most o~ which consist of a pot-shaped insulating body having switching contacts and electrical connection means disposed therein, and a generally pot-shaped closure cap for supporting the bimetallic disc. Furthermore, a thermoswitch of similar construction has become known which . , ~ comprises a rectangular insulator which accommodates the - switching contacts, which are embedded in a rectangular depression in the insulator.
` A low price is vital to the marketing of such devices, so that it is necessary for the manufacture thereof to be virtually fully automatic. However, the known devices involve a very complicated method of production, particularly with regard to insertion of the parts into the pot-shaped depression, and such production is possible only with considerable expenditure, i.e. the parts have to be supplied i~ singly.
... .
Another disadvantage is that adjustment operations needed on these devices, particularly adjus~ment of the contact gap, in most cases cannot be performed completely automatically.
In many domestic appliances it i$ necessary to incorporate a plurality of temperature responsive devices to guarantee the safety of the appliance. Thus, for example, it is usual in coffee machines to provide a temperature responsive ~'~7 : - , , : , , , , : , -,. , . . . , :
means in the form of a melting fuse, in addition to a temperature regulator, which fuse interrupts the supply of current at a temperature below a critical temperature of the heating means or the synthetic plastics housing. This involves the dis-advantages that after it has been triggered, further current cannot be supplied until the fuse has been replaced, and such fuses exhibit considerable tolerances with regard to the temperatures at which they respond, so that with increasing calcification of the heater the fuse may respond prematurely.
In order to avoid unnecessary fuse changing it has become known to use instead of the melting fuse a temperature limiter which, following switch-off and rectification of the source of the fault, can be switched on again by hand.
An object of this invention is largely to avoid these disadvantages and to provide an improved temperature responsive device which can be assembled and adjusted fully automatically.
According to this invention there is provided a temperature responsive device comprising an electrically in-sulating body; a groove in a surface of said insulating bodyand extending in a length direction the total extent of said insulating body; a recess in a surface of said insulating body opposite to the surface thereof having said groove therein; a spring-loaded movable contact carrier and a fixed contact carrier having a predetermined bending point provided in said groove and ; carrying respective switching contacts for cooperation with one another; two electrical connectors disposed in said groove and each extending outwardly of said insulating body from a respect~
; ive end of said groove, each electrical connector being electric-ally connected to a respective one of said switching contacts via the respective one o~ said contact carriers; a heat conductive ., ~ .

member secured to sai~ insulating body; a dished bimetallic disc responsive to the temperature of said heat conductive member - disposed in said recess and retained in said recess by said heat conductive member; and a pin which extends through a bore provided in said insulating body between said bimetallic disc and said movable contact carrier for transmitting temperature-responsive movement of said bimetallic disc to said movable contact carrier to make or break said switching contacts.
Preferably said recess in said insulating body is ; 10 circular and said heat conductive member includes a circular projection which is received in said recess.
In accordance with the invention, the insulating body has a groove which extends the entire length of the body.
This facilitates fully automatic assembly because the parts can be introduced into the groove, the individual contact parts and electrical connectors being fed to the installation site in , a continuous strip and being separated by cutting means just briefly prior to location in the insulating body. The advantage of this is that the contact-carrying parts do not have to be singled out from a total quantity whereby the contacts would be dirtied by the constant rubbing of the parts against one ~,~
another.
^ The contact carriers and electrical connectors are during assembly located in the insulating body in such a way that the movable spring-loaded contact carrier and an electrical connector are inserted into the groove opening at one end of the body while the fixed contact carrier with the second electrical connector are introduced into it at the opposite end. Provided in the contact carriers and electrical connectors are bores to accommodate a rivet by means of which in each .~, :
.', ' .'' ' :~ . , , , ' ' ' ' ' ' ' : ' ' ' ' ' " ' ' ;5~
case the contact carrier and the electrical connector are secured to the insulating body.
The fixed contact carrier has a predetermined bending point which may for example be formed by a fairly long aperture at the root of the contact carrier. Automatic adjustment is effected in that the fixed contact carrier is so angled upwardly that the movable contact does not touch the fixed contact at the limit tolerances which are anticipated.
The movahle contact carrier is only moved by a downwardly directed force and a~ter closure of the contacts, it is pressed farther in the closure direction by a certain amount.
The circular projection of the heat conductive member or baseplate serves as a mounting for the dished bi~
metallic disc, and after the insulating body and the baseplace have been fitted together, the bimetallic disc is ~nclosed in the circular recess. The pin which extends between the bi-metallic disc and the movable contact carrier is displaceably mounted in a circular bore in the insulating body and transmits ~ . .
to the movable contact carrier any fluctuation in the height of convexity of the bimetallic disc due to the effects of temperature.
,'! Preferably the insulating body and the heat conductive baseplate are so constructed that different - ~-dimensions of the bimetallic disc can be accommodated in the , circular recess, 50 that various baseplates and bimetallic discs of different diameters can be used in conjunation with a uniform insulating body.
The invention also extends to a combination of a ~ -plurality of temperature responsive devices each as recited above, the heat conductive members of all of the devices being constituted by a baseplate of heat conductive material , which is common to all of the devices and the insulating bodies r ~ 4 -'"
', . , ' . . ' . . ' , ' ! ' ', ' . ' .,, ' , , . ' 3$5~
of the devices being individual to each of the devices.
Suoh a combination is particularly useful when it is necessary to equip a domestic appliance with an additional safety element to supplement a temperature regulator, and overcomes disadvantages associated with use of two individual and separate thermostats.
The individual insulating bodies of the combination can be located either directly beside one another or at a predetermined distance from one another on the baseplate.
It is advantageous for manufacture of the combination to be fully automatic, a particularly rational production being provided for if assembly of the various insulating bodies, bimetallic discs, transmission pins and so on, occurs simultaneously on the common baseplate for all of the devices. Similarly, the necessary adjustment can be undertaken simultaneously on all of the devices.
Thus, within the time in which only one individual thermostat can be produced in known manner, a plurality of devices can be simultaneously assembled to provide the combination of the invention. A further advantage is the simple assembly of the combination in the domestic appliance, since only one fixing is needed for several devices. Furthermore, the combination ensures even heat transference from the point of attachment through the common baseplate to the bimetallic ~'J, discs, so that the heat gradient between the individual devices - remains as low as possible. The advantage of this is that when : : ~
adjusting the switch~off temperatures, tolerances can be more generously chosen and this in turn lowers the cost of manufacture. -The combination may comprise bimetallic discs having different response temperatures and siwtching contacts having different functions. Thus it is possible, according ,. .

to the intended purpose, to combine temperature regulators, temperature monitors and temperature limiters with one another as desired.
In a preferred embodiment, lugs project from the baseplate to hold the insulators being bent over to engage recesses in the region of the corners of the insulating bodies. In each case two adjacently disposed insulating bodies can be gripped on each side simultaneously by one lug.
The heat conductive baseplate can comprise tangs which extend laterally of the insulating body and which, for the attachment of the temperature responsive device in a domestic ~ -appliance, can be provided with apertures, slots or the like.
It is possible for the tangs to be disposed on one or on both sides of the insulating body.
` Alternatively the device can include a threaded screw disposed in the heat conductive member, enabling the ~ device to be screwed onto a surface which is to be monitored.
