Definitions

  • the invention relates to a technology box according to the preamble of patent claim 1 and a toilet seat set designed with such a technology box.
  • WO 2016/020409 A1 discloses a toilet seat set in which electrical consumers, for example a seat heater and a sensor, are integrated on the seat side. These consumers are supplied with power via a control unit integrated in a technology box, the technology box being placed on the ceramic and preferably the seat and the cover being mounted on the technology box. This is therefore part of the toilet seat set.
  • toilet seat sets are described in which elements for contactless data and energy transmission are arranged in a technology box, which are connected to the functional components of the toilet seat Toilet seat set are in terms of energy and data transmission in operative connection.
  • the seat heating is arranged on a carrier that also contains parts of the functional components that enable contactless near-field transmission and the associated control electronics.
  • a similar toilet seat set in which the functional components and the control electronics are also arranged in a type of technology box, with the energy supply of consumers accommodated in the toilet seat, for example a seat heater, also being contactless.
  • Toilet seat sets are also known, in which, for example, a fragrance capsule can be used interchangeably in the toilet seat, via which a fragrance for odor neutralization or odor masking is released.
  • a fragrance capsule can be used interchangeably in the toilet seat, via which a fragrance for odor neutralization or odor masking is released.
  • the scent is released in the direction of the room, so that the entire room is exposed to the scent and can therefore be perceived individually as unpleasant.
  • solutions in which air is sucked out of the ceramic and filtered to neutralize odors Such solutions require a considerable outlay in terms of device technology.
  • a toilet seat set with a technology box, a toilet seat and a toilet lid which has a deodorizer inside the technology box. Air is extracted from the ceramics, guided through the deodorizer inside the technology box and then passed out of the technology box into the ambient air.
  • a method for deodorizing a toilet and a deodorizing toilet are known.
  • a toilet has a technology box, via which a toilet seat and a toilet lid are held pivotably in the form of a detachable connection.
  • Several functional units are provided within the technology box, one of the functional units being a deodorizer. Air is sucked in from the ceramic, guided over the deodorizer and fed back into the ceramic.
  • the invention is based on the object of creating a technology box and a toilet seat set which, with little effort, enables odors that arise when using a toilet seat set to be superimposed in a targeted manner.
  • the technology box according to the invention is designed for a toilet seat set, which is connected to the technology box via swivel joints and which in turn can be fixed to a ceramic using fastening means.
  • functional components and control electronics/power electronics of the toilet seat set are arranged in a housing of the technology box, with one of these functional components being a deodorizer (device for overlaying odors).
  • This is designed with a fan, through which air is sucked in through an air inlet formed in the technology box and discharged through an air outlet in the direction of the ceramic.
  • a scenting agent is arranged in the air flow between the air inlet and the air outlet, which scenting agent can be designed, for example, as scenting agent pellets or granules.
  • the scenting agent is arranged in a container that can be removed and reinserted from the technology box. Thus, the replacement of the scenting agent can be easily implemented by a user.
  • the scenting agent is preferably arranged in a drawer which is guided in a deodorizer housing in such a way that the drawer can be pulled out of the technology box in order to replace the scenting agent.
  • a drawer solution of this type enables the user to exchange the scenting agent and thereby select a new loading of the drawer from a large number of scents.
  • the scenting agent is held in a container that can be inserted into the technology box.
  • This container can be held inside the technology box via a catch and/or some type of bayonet catch.
  • the container can have a thread which can be brought into engagement with a thread on the technology box side in order to fix the container in position.
  • the container can be held in a plug-in position by means of a type of spring clip.
  • Alternative flaps, latches or threaded fasteners for positioning the container using an additional component can also be implemented.
  • Replacing is particularly easy if the scenting agent is accommodated in a cassette/capsule, which in turn is held in the drawer so that it can be replaced.
  • This holder is preferably designed in such a way that the cassette can be stored in the correct position (poka-yoke solution).
  • Cassettes/capsules of this type are offered by different manufacturers as scent enhancers, so that in a modular system several drawers can also be used for different types of cassettes.
  • Adaptation to different types of cassettes/capsules can also be carried out using suitable adapters that are placed in the receiving space of the drawer.
  • suitable adapters that are placed in the receiving space of the drawer.
  • the charging of the air with the fragrance is particularly effective when the receiving space for the cassette is open in the direction of flow, so that the air can enter the receiving space without excessive pressure loss and be fed out of the receiving space of the drawer.
  • the air flow can also be routed past these elements for cooling.
  • the fan can be operated at variable speeds via the control electronics.
  • the stability of the technology box is particularly high when the housing has a housing base which is connected to a housing support to form a type of inner housing.
  • functional components and control electronics are arranged in a space encompassed by the housing base and the housing support and are covered on the outside with an outer shell that determines the visual appearance.
  • the stability is then provided by the inner housing with the housing base and the housing support, while the design is essentially determined by the outer shell.
  • the air flow is particularly compact if the air inlet is formed on a rear wall of the technology box and the air outlet, as mentioned above, is formed on the ceramic side, so that the air can be guided approximately in a vertical plane, for example.
  • the structure of the technology box is further simplified if the deodorizer housing is formed or held on the housing base, with flow cross-sections for guiding the air flow being delimited in sections by the housing base and the housing support.
  • the flow guidance within the technology box is particularly precise if an outlet channel is formed downstream of the drawer, which extends in sections along the housing base and is covered by a cover at the top (towards the housing support). This ensures precise airflow with minimal pressure loss.
  • the installation of the system is particularly easy if the fan is held on the housing support so that the fan can be positioned by screwing the housing support to the housing base.
  • the air flow is particularly simple if it is guided approximately in a vertical plane or in a vertical area with respect to the bearing surface of the technology box on the ceramic.
  • the air inlet is arranged higher than the air outlet in relation to this bearing surface, so that the air flow is guided downwards in the direction of the ceramic.
  • the technology box can be designed with a communication module to which an external control element, for example a handheld, is assigned, via which the fan and possibly also other functional components of the toilet seat set or the technology box can be controlled.
  • an external control element for example a handheld
  • Such functional components can be, for example, a swivel drive for the toilet seat or the toilet lid, toilet seat joint arrangements, a sensor system, lighting means, an energy source and/or other components required for operating the toilet seat set.
  • the structure of the technology box is particularly compact when its housing is stepped back towards the air outlet.
  • the aforementioned sensor system can have, for example, a document sensor, a proximity sensor, a sensor for detecting vital parameters, a temperature sensor (seat heating) and/or an acceleration sensor.
  • the fan can also be activated via a button or switch arranged on the technology box or the toilet seat set, or automatically via the control electronics.
  • the deodorizer in particular the fan, can be activated as required or automatically after going to the toilet.
  • the drawer system described above is, for example, also designed in such a way that scenting agents from one's own production can be accommodated, so that the user is not limited to the existing scenting capsules.
