Definitions

  • the present invention relates to one of an electric motor, in particular one electronically commutated direct current motor (EC motor), operated pump for Supply of a heating or air conditioning system for a building, with a housing, comprising a pump housing in which an impeller is arranged, and comprising a motor housing in which electrical and / or electronic components for Operation of the engine are arranged.
  • EC motor electronically commutated direct current motor
  • Such heating pumps are well known. They mostly supply as part central heating the heating system from a central point. This Pumps generally consume less than 100 watts and get their electricity from the grid. A suitable network connection stands for usually available at a central location. Recently, so-called “Decentralized” pumps known, each only a single radiator or are assigned to a few radiators arranged in a room and only theirs Carry out supply of heating medium. These pumps can because of lower requirements of correspondingly lower performance. you will be also supplied via the building's power grid.
  • the object of the present invention is a pump of the type described in the introduction Type to create, which is simple in terms of their electrical connection easy to handle and therefore versatile to use and also an optical makes an appealing impression.
  • the idea according to the invention lies in the energy supply of the pump alone by a battery mechanically connected to the pump.
  • the pump is thus self-sufficient with regard to their care. This way, the distracting Supply cables can be avoided and the pump can be used flexibly and can be installed comfortably.
  • the invention manifests itself in that in or on Housing, i.e. at a defined point on the pump, a battery for Main supply of the motor and, if it is a regulated pump, the electronics controlling the motor is arranged. So the battery is not intended only for emergency care.
  • the electronics are respectively the electronics the circumstance of the reduced voltage of adapted for example 12 V or 24 V.
  • the invention can be used particularly advantageously in pumps whose Power consumption with less than 10 watts, especially less than 2 watts, is comparatively low compared to conventional heating pumps.
  • Such one Performance range is common especially with the decentralized pumps mentioned do not have to supply much more than just a radiator.
  • the pump is in the flow or return in the immediate vicinity or directly attached to the heat exchanger, especially the radiator. So can the pump takes the place and role of the radiator valve. Because in this If the pump is integrated in the radiator to a certain extent, it refers to the Invention on the entire system of heat exchangers attached to it Pump.
  • the battery is certainly particularly advantageous to design the battery to be rechargeable. This saves a considerable part of the costs on the one hand and the costs on the other Protects the environment.
  • Such rechargeable batteries also known as rechargeable batteries are with relatively high capacities in a small design at constantly falling costs commercially available.
  • the known Ni / Cd batteries or Lithium ion batteries used which are characterized by their long life and their Characterize reliability at a low price. It can also be beneficial to use other modern batteries with high capacity and small size.
  • the battery could be stationary, so that the user with the installed pump for a certain charging time with a cable an external voltage source with the interposition of a charger connect to charge the battery.
  • the (rechargeable) battery which consists of a pack of several individual batteries, as well as accessible and detachably attached in or on the motor housing.
  • the user can then replace the battery at any time as needed. A service technician is not necessary for this.
  • the battery is in such a interchangeable battery pack is arranged that simply as a compact component the motor housing can be plugged on, the contacts to when plugging Close the motor automatically.
  • cordless screwdrivers such battery packs can be handled by everyone.
  • To endanger users To be excluded by a pump running in generator operation is at Conception of the contacts of course make sure that they are not free accessible but covered.
  • the battery pack can then advantageously plugged into a corresponding charging station supplied by the mains voltage and to be charged.
  • the charging station installed in a central location can be the Pick up and charge the batteries of several pumps.
  • a display instrument on the pump or battery on which the Charge status of the rechargeable battery can be read can be supplemented or replaced by an alarm device that audibly and / or triggers an optically perceptible alarm as soon as the charge level falls below critical value.
  • an alarm device that audibly and / or triggers an optically perceptible alarm as soon as the charge level falls below critical value.
  • the battery is at least partially from a solar cell that is adjustable in particular in relation to the light charged, which is connected to the battery. Even if this energy source is not can accomplish the full charge, so it sometimes carries to a large extent. Because of the large available area and the Possibility of skillful integration into the design, it is particularly advantageous that Solar cell on the surface of the heat exchanger, especially the radiator, attached and connected to the battery via a cable. With today known powerful solar collectors, which have a high yield at relative To guarantee a small area, such an additional power supply is simple realizable. The possibility of adjustment allows the light source to be adjusted Both a lamp and the sun can be used optimally.
  • the figure shows a centrifugal pump according to the invention, which in this particular case is built directly into the connecting flange of a radiator 1 and has an output of about 1 watt.
  • the pump has a housing that is on the one hand in a Impeller 10 surrounding pump housing 2 and on the other hand in a motor housing 3rd divides in which electrical and / or electronic components for operating the Motors are arranged.
  • the pump housing 2 is in this particular case Connection flange of the radiator 1 formed, which itself for installing a Corner valve is provided. This forms the spherical pump housing 2, in which an inlet line 4 protrudes and into which an outlet line 5 opens.
  • the Pump is screwed into a nozzle 7 by means of a thread 6.
  • the connecting piece 7 has a corresponding Internal thread. Sealing between the pump and the connector 7 happens by means of a 0-ring 14.
  • the impeller 10 sits with its central Suction mouth directly on the feed line 4.
  • the pump itself has an EC motor 8 on its electrical side and on the hydraulic side on an impeller 10 held on the shaft 9.
  • a battery for supplying the motor and the motor controlling electronics arranged.
  • the battery is a package 11 with rechargeable batteries that are accessible to the user from outside and above Snap locks 12 releasably attached to the motor housing 3.
  • Package 11 is thus plugged onto the motor housing 3 as a compact component Plug in contacts not shown to the motor automatically.
  • the Battery pack 11, a display instrument 13 is integrated, on which the state of charge Battery is readable.
  • an alarm device 15 is provided, which one Visible alarm triggers as soon as the state of charge a critical Falls below value.
  • In the battery pack 11 is an adjustable via a hinge Solar cell 16 attached, which is connected to the rechargeable battery and which contributes to their charging.
