Always switch off the control before cleaning a cooker even if it is not being mantled.
Do not let metal cooking foil come o contact with spiral type elements. Take care if the cooker is mounted on eels and likely to be interfered with by youngsters.
Never leave fat in a pan unattended on hotplate and take care with the position handles of vessels containing boiling liquid in the presence of children.
Do not attempt to remove pieces of broken toast from a toaster using a knife other metal object. Pull out the plug tore releasing the obstruction. Read the rest of this entry »
Aschematic diagram of the internal workings of a pod-type thermostat. This type is used in appliances that have a variable temperature control. It consists of an oil-filled pod connected to the switch by a capillary tube. When the oil in the pod is heated or cooled, it expands or contracts in the tube and operates a diaphragm. The diaphragm acts on the switchgear thus breaking the circuit and in this instance, ‘making’ the other. The cooling oil contracts, pulling the switch the opposite way — back to its original position; the process repeats if temperatures change. Read the rest of this entry »
Many household appliances have some means of governing the temperature at which they operate. Examples include the regulation of high temperature ovens and heaters by switching elements on or off and, at the other end of the scale, the control of low temperatures in refrigerators and freezers by turning the compressor motor on or off.
A thermostat is an automatic device for regulating temperature. They range in type from the simple single action switch, which turns off or on at one pre-set temperature, to the fully adjustable type, which can be adjusted within a given range. Read the rest of this entry »
The toaster is another appliance that uses heating elements and, in most instances, a bi-metal strip thermostat to control the length of time the bread is exposed to them. This, in turn, relates to the degree of browning required by varying the position of the bi-metal contact points. When bread is inserted, a latched spring system is actuated to hold the bread carrier in place. At the same time, it makes a switch contact to supply power to the elements. The heat from the elements toasts the bread and also heats the bi-metal strip, causing it to bend. Read the rest of this entry »
The brush roll is supported on bearings at each end so the barrel rotates freely. Types of bearings, barrels and brushes differ from model to model as well as between manufacturers. Some manufacturers supply individual parts for the brush roll, such as brush strips, bearings and barrel; others supply only complete assemblies. The brush roll on some models may have removable brush strips, whereas others may be a solid brush roll of wood or plastic with fixed brushes. A small selection is shown here to highlight the differences. Read the rest of this entry »
Cord rewinds are now found on all types of cleaners, from simple hand-operated versions to the fully automatic rewind at the touch of a button. Many auto cord rewind systems use open coil springs and great care should be exercised if a stripdown of these systems is called for. Protection for the eyes is recommended. Goggles afford adequate protection from the spring itself or any item that it may throw out in the event of its slipping from position.
Operation of the cord rewind relies on tensioning of the rewind spring as the cord is pulled out for use. A small brake pad prevents the immediate return of the spring and cord drum to its original position. Read the rest of this entry »
