Definitions

  • the present invention relates to a powered by an electric motor, in particular an electronically commutated DC motor (EC motor), pump for supplying a heating or air conditioning system of a building, comprising a housing, comprising a pump housing, in which an impeller is arranged, and comprising Motor housing in which electrical and / or electronic components are arranged to operate the motor.
  • EC motor electronically commutated DC motor
  • Such heating pumps are well known. They usually supply the heating system from a central location as part of central heating. These pumps generally have a power consumption of less than 100 watts and draw their power from the grid. A suitable network connection is usually available at a central location. For a short time, so-called “decentralized” pumps have also been known, which are each assigned to only a single radiator or a few radiators arranged in a room and only manage their supply of heating medium, see eg DE 199 39 522 , These pumps may be of correspondingly lower power because of lower requirements. They are also supplied via the voltage network of the building.
  • a disadvantage of the previously known pumps is that the power is supplied via lines that need to be routed to the decentralized pump out. These lines, which are sometimes laid over relatively long distances, affect the visual impression of the entire system of radiator and attached pump. They also help make these decentralized pumps uncomfortable in their maintenance and handling.
  • Object of the present invention is to provide a pump of the type described above, the handle easily in terms of their electrical connection with a simple structure and thus can be used in many ways and also makes a visually appealing impression.
  • the idea of the invention is to accomplish the power supply of the pump solely by means of a battery mechanically connected to the pump. This guarantees complete independence from an external power supply, at least for the life of the battery or batteries.
  • the pump is thus self-sufficient in terms of their supply. In this way, the disturbing supply cables can be avoided and the pump can be used flexibly and easily mounted.
  • the invention manifests itself in that in or on the housing, ie at a defined point on the pump, a battery for main supply of the motor and, if it is a regulated pump, the motor controlling the electronics is arranged.
  • the battery is therefore not intended solely for emergency supply.
  • the electrical or electronics is the circumstance of the reduced voltage compared to the network, for example, 12 V or 24 V adapted.
  • the invention can be used in pumps whose power consumption is less than 10 watts, in particular less than 2 watts, relatively low to conventional heating pumps.
  • a power range is common especially in the mentioned decentralized pumps, each of which does not have to supply much more than just a radiator.
  • Such a pump is accordingly in the flow or return in the immediate vicinity or attached directly to the heat exchanger, in particular the radiator. So the pump can take over the place and the role of the radiator valve. Because in this If the pump is to some extent integrated in the radiator, the invention relates to the entire system of heat exchangers of the pump attached thereto.
  • Such rechargeable batteries are commercially available at relatively high capacities in a small design at constantly decreasing costs.
  • the known Ni / Cd batteries or lithium ion batteries are used, which are characterized by their long life and reliability at a low price. It may also be advantageous to use other modern, high capacity, small size batteries.
  • the battery could be mounted stationary in a particular embodiment, so that the user must connect the installed pump for a certain charging time via a cable to an external power source with the interposition of a charger to charge the battery.
  • the batteries to be used advantageously have a capacity of at least 20 Ah, so that pumps can run at 1 watt power consumption for at least 200 hours.
  • the operating time can be extended by a corresponding factor.
  • the (rechargeable) battery which consists of a pack of several individual batteries, as well as accessible and detachable mounted in or on the motor housing.
  • the user can then replace the battery whenever needed. A service technician is not necessary.
  • the battery is arranged in such a replaceable battery pack, which is simply plugged as a compact component on the motor housing, which automatically close when plugging the contacts to the engine.
  • cordless screwdrivers such battery packs are manageable by anyone.
  • the battery pack can then be inserted and charged in an advantageous manner in a corresponding over the mains voltage supplied charging station.
  • the charging station installed at a central location can pick up and charge the batteries of several pumps.
  • a display instrument on the pump or the battery, on which the state of charge of the rechargeable battery can be read.
  • Such an instrument can be supplemented or replaced by an alarm device that triggers an acoustically and / or visually perceptible alarm as soon as the state of charge falls below a critical value. By entering the alarm state, the user is encouraged to change the battery pack.
  • the battery is at least partially charged by a particular adjustable in position to the light of the solar cell, which is connected to the battery.
  • a particular adjustable in position to the light of the solar cell which is connected to the battery.
  • this source of energy can not accomplish full charge, it does contribute to it sometimes.
  • the powerful solar collectors known today which guarantee a high yield with a relatively small area, such an additional power supply can be easily realized.
  • the possibility of adjustment makes it possible to optimally use the light source, which can be both a lamp and the sun.
  • the figure shows a centrifugal pump according to the invention, which is installed directly in the connecting flange of a radiator 1 and has a power of about 1 watt in this particular case.
  • the pump has a housing, on the one hand in a the Impeller 10 surrounding pump housing 2 and on the other hand in a motor housing 3, in which electrical and / or electronic components are arranged for operating the motor.
  • the pump housing 2 is formed in this particular case of the connection flange of the radiator 1, which is provided in itself for installation of an angle valve. This forms the spherical pump housing 2, in which a feed line 4 protrudes and into which a drain line 5 opens.
  • the pump is screwed by means of a thread 6 in a socket 7.
  • the connecting piece 7 has a corresponding internal thread. Sealing between the pump and the connecting piece 7 is done 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 an impeller 10 held on the shaft 9 on the hydraulic side.
  • a battery for supplying the motor and the motor controlling the electronics is arranged on the motor housing 3.
  • the battery is a package 11 with rechargeable batteries that are accessible to the user from the outside and attached via snap closures 12 releasably attached to the motor housing 3.
  • the package 11 is thus plugged as a compact component on the motor housing 3, wherein automatically close when plugging contacts to the motor.
  • the battery pack 11 is integrated a display instrument 13, on which the state of charge of the battery can be read.
  • an alarm device 15 is provided which triggers an optically detectable alarm as soon as the state of charge falls below a critical value.
  • a solar cell 16 which can be adjusted by means of a hinge is attached, which is connected to the rechargeable battery and contributes to its charging.
