Title: Improvements in and relating to Electric Heating Devices.
IPC: A47J36/24
Filed: 1966-12-29
Abstract: 1,161,830. Temperature control arrangements. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 29 Dec., 1966 [29 Dec., 1965], No. 58241/66. Heading H2H. [Also in Divisions G3 and H5] A positive temperature coefficient thermistor 11 is connected in series with a reactor 12 and resistor 13 to provide a self-regulating arrangement which automatically varies the current over a predetermined range of ambient temperature determined by the intersection of the characteristic 18 of members 12, 13 (independent of temperature) with the characteristics 14-17 of the thermistor 11 corresponding to various ambient temperatures. In a typical cycle of operation an increase in temperature at the operating point 19 (intersection of characteristics 14, 18) produces a slow fall in current corresponding to the operating points 20, 21, 22. The point 22 (characteristics 17, 18 tangential) is unstable and hence there is a sudden change to the operating point 23, so producing an abrupt drop in current. Thereafter the temperature decreases, producing a gradual rise in current corresponding to the operating points 24, 25, 26, at which last-mentioned unstable point the characteristics 14, 18 are tangential so producing a sudden increase in current corresponding to a return to the initial operating point 19. In one application of the invention, Fig. 4 (not shown), the reactor comprises the coil (34) of a solenoid switch responsive to the sudden changes of current to actuate the heating current control of apparatus to whose temperature the thermistor is sensitive. In another application, Fig. 5 (not shown), the thermistor and resistor constitute the heating element of a device for warming a baby's feeding bottle (see Division H3-H5), this arrangement functioning as a self-controllable heating device.
