Definitions

  • the invention relates to an electrical machine comprising a housing, a plurality of power contact elements and a ground contact element disposed on the housing, the power contact elements and the ground contact element configured for connecting the electrical machine to a power supply device and the power contact elements forming a terminal for being connected to the power supply device by a single connector.
  • Document EP 2 559 804 A1 discloses an electrical machine as defined above.
  • the electrical machine is combined with a gas compressor driven by the electrical machine, the electrical machine and the gas compressor hermetically enclosed in a housing.
  • the gas compressor serves for driving a working medium in a heat pump adapting the inverse Rankine cycle and established in a household appliance that is a laundry dryer, the heat pump provided for cyclically heating and cooling an air flow circulating for drying laundry.
  • the electrical machine is designed to be powered by three-phase alternating current, and consequentially has three power terminals combined into a terminal placed on the housing for connecting to a power supply device.
  • Document EP 2 513 368 B1 discloses a household appliance embodied as a laundry dryer and including a heat pump with a gas compressor and an expansion device, the heat pump operating in the inverse Rankine cycle for pumping heat from a heat sink to a heat source.
  • a working medium that is conventionally also termed "refrigerant" circulating between the heat source and the heat sink is cyclically evaporated and condensed. Drying of humid ware in the household appliance is effected by an air flow passing along the drying ware and guided in an essentially closed circuit. Therein the air flow is heated by the heat source prior to passing the humid ware, and cooled by the heat sink after passing the humid ware and loading itself with humidity. The cooling provides for the humidity in the air flow to condense and precipitate from the air flow. Precipitated humidity is separated and collected for later disposal.
  • Document EP 2 640 885 B1 also discloses a household appliance embodied as a laundry dryer including a heat pump operating in the reverse Rankine cycle.
  • the heat pump includes a gas compressor for compressing and driving a working medium, and a control device configured for providing electrical power to the gas compressor and controlling operation of the gas compressor.
  • Several sensors are also provided in the household appliance and associated to the control device to take measurements during drying operation, and forward related measured data to the control device for use in controlling drying operation.
  • Document EP 2 732 090 B1 also discloses a household appliance particularly embodied as a laundry dryer and including a heat pump.
  • the air flow applied for drying is guided in an open circuit, taken in from the household appliance's environment by a suitable blower. This air flow is first heated by the heat pump's heat source, then passed along humid ware to be dried, and then cooled and stripped from entrained humidity in the heat sink. Finally the air flow is exhausted back to the environment.
  • Document EP 2 985 466 A1 discloses various embodiments of a gas compressor for application in a heat pump in a household appliance, the gas compressor embodied as a rotary piston gas compressor or a reciprocating piston gas compressor.
  • Document EP 1 902 496 B1 discloses an electric power terminal feed-through adapted to be installed in a housing, comprising a metallic body with a cylindrical sidewall, at least one current conducting pin extending through the body and a seal sealing the at lest one current conducting pin to the body.
  • the seal may be a preformed insert including glass.
  • a household appliance is an appliance determined for use in operating a private household to effect a specific and predetermined material purpose.
  • the common solution for establishing a common ground potential in an appliance is easy to implement by the manufacturer of an electrical motor to be built into an appliance by merely including some tabbed lug in the construction as a point of contact

  • the common solution requires at least two different types of connection to be made to an electrical motor of the type defined in the initial paragraph above, namely one type of connection to the power contact elements, and another to the ground contact element. This requires at least two steps in a manufacturing process.
  • the proper contacting of all present power contact elements may be prone to errors by juxtaposing connectors.

Thus all required connections to the electrical machine may be attached by mounting a single connector which provides all necessary contacts to the power supply and to common ground.
  • ground contact element By having the ground contact element longer than the power contact elements it is further assured that upon mounting the connector the ground contact element is connected first, thereby attaching the housing to common ground and ascertaining that, should any connection to the power contact elements within the housing be faulty by making an undesirable contact to the housing, prevention from power potential being attached to the housing is avoided. Instead the ensuing short to common ground gives a clear and easily diagnosed error signature.

Instead the ensuing short to common ground gives a clear and easily diagnosed error signature. Further it is assured that ground contact element 4 is the last to be released from connector 15 as connector 15 is removed from terminal 6, which retains the connection to common ground as long as possible and provides safety against exposure to undesirable power potential on removing connector 15.
  • the relatively large ground contact element is readily applied to verify proper attachment of the connector to the terminal.
  • the plurality of power contact elements 3 is three power contact elements 3, implying that the electrical machine 2 is to be powered by three-phase alternating current that is provided by power supply 5.
