Definitions
- the invention relates to a toilet seat with suction openings for extracting air from a toilet bowl, comprising a cavity in the seat connected to the suction openings, a suction device and filter means, the seat having a fastening region and a front region. Furthermore, the invention relates to a toilet equipped with such a seat.
- GB-A 2 178 456 discloses a WC
- This toilet seat has a circumferential cavity into which air can be sucked out of the toilet bowl into the hollow space via a plurality of round suction openings on the underside of the seat. This is done via a fan arranged outside the toilet seat, which conveys the air sucked in through an activated carbon filter.
- US-A-0 075 677 shows a toilet seat and a toilet with suction of air from the toilet bowl.
- CH-A-469 869 shows an intermediate ring below a toilet seat which has a channel with a single slot-shaped opening on one side of the toilet bowl. A second opening on the other side of the toilet bowl is provided as an air outlet to create an air curtain over the toilet bowl. The extracted air is not led into a filter.
- each at least one of the suction is designed as a slot and in particular the slot or slots extends substantially from the attachment area to the front area or extend.
- suction openings are provided only laterally of the longitudinal center line of the toilet seat and not in the front area itself; If suction openings are also provided there, then they are not designed as slot-shaped openings there. It has been shown that the seat opening area adjoining the front area is to be used in particular for the subsequent flow of fresh air into the bowl, which is rather disturbed by slit-shaped intake openings in the front area.
- the slit-shaped intake openings are provided in an embodiment in the bowl-side Sei.tenwand the seat.
- the arrangement of the slots is provided on the underside of the seat.
- a combination of sidewall-shaped and underside slots is preferred.
- the suction slots are at the bottom with.
- the cavity into which the air from the toilet bowl enters via the suction openings does not extend circumferentially as a cavity in the whole seat.
- two cavity parts are formed, so that in the front of the seat no cavity is present, is sucked into the air.
- At least one of the cavity parts preferably has a changing cross-sectional area at least subsequent to the suction opening. This, in combination with the design of the intake openings, makes it possible to achieve a uniform, in particular largely laminar, air flow in the seat.
- the cross-sectional area increases from the respectively closed end of the cavity part to the open end or the connection end of the two cavities. This allows a good flow of a filter means arranged in the seat.
- a suction device is arranged in the seat per cavity part. With this arrangement, the promotion of an amount of air can be achieved that largely avoids the odor from the toilet bowl and a disturbing fan outside the seat can be omitted. Further, it is preferred if the filter means are also housed in the seat. Also for this arrangement, the embodiment with two suction means or blowers is particularly advantageous.
- Figure 1 is a plan view of a toilet seat according to the invention, wherein the top of the seat is shown as partially transparent;
- Figure 2 is a sectional view taken along the line B-B of Figure 1 with two different embodiments of the intake ports in the left and right half of the figure; and Figure 3 is a view of a seat from below.
- FIG 1 shows a toilet seat in plan view from above, ie in the direction of the seat. This is assumed to be transparent in Figure 1, so that the cavity and the other elements in the seat can be seen.
- the toilet seat 1 has a conventional shape with an annular seat with a seat opening 11.
- the seat is designed symmetrically to its longitudinal center line A and has in the rear part of a mounting portion 12, which has not shown fastening means for arranging the seat to a toilet.
- the attachment area is essentially the area behind the imaginary line D, which touches the seat opening.
- the seat is arranged in a known manner so that it is pivotally attachable to the toilet.
- a front portion 13 of the seat may be defined to be in front of the imaginary line C which is tangent to the seat opening 11.
- the design of such a seat made of plastic, wood or other materials is known to the person skilled in the art and in principle need not be further explained here.
- the seat according to the invention has a cavity 4 in its interior.
- the cavity 4 is located in two hollow units 5 and 6 located on both sides of the longitudinal center line A tert rushes. These cavity parts 5 and 6 are in the attachment region 12 with each other. On the other hand, they are closed in the front region 13 of the seat 1 or are not in communication with each other. According to the invention are now in the seat on both sides of the line A slot-shaped suction 2, 2 ', through which air from the toilet bowl is sucked into the cavity provided. These elongated slots essentially extend between the front region 13 and the attachment region 12, but preferably not into it.
- the arrows a indicate how air enters the cavity 4 or the lateral cavity parts 5, 6 from the seat opening 11 or from the toilet bowl through the slot-shaped openings 2, 2 '.
- FIG. 1 the arrows a indicate how air enters the cavity 4 or the lateral cavity parts 5, 6 from the seat opening 11 or from the toilet bowl through the slot-shaped openings 2, 2 '.
- the cavity parts 5 and 6 are designed so that their cross-sectional area changes over part of the cavity. It is apparent that the cavity part 5 at its front end region 5 ', on which it is closed apart from the slot opening 2', initially has a small cross-sectional area and widens in the direction of the attachment region 12. For the cavity part 6, a similar course is shown with a slightly different shape. The change in the cross-sectional area, in conjunction with the shape of the slot-shaped intake openings 2 and 2 ', is selected such that a flow which is as uniform as possible, in particular laminar, is established in the respective cavity part at least in the region of the intake slots. The air flow in the cavity is indicated by the arrows b.
- the suction means which sucks the air from the toilet bowl via the suction slots, two fans 8 and 9, which are each associated with a cavity part 5 and 6 respectively.
- It may be, for example, known axial fan or radial fan, which in particular by a low-voltage electric motor, driven by, for example, 12 volts voltage.
- the fans 8 and 9 are then operated via a transformer, which transforms the mains voltage of the household network for the blower motors.
- a circuit may be provided which, after switching off or relieving the switch, continues to operate the suction device for some time in order to allow the odor extraction to continue for some time after the WC has been used.
- switch-on means and time circuits are known to the person skilled in the art and need not be explained further here.
- a single blower can be provided, which is arranged so that it can suck in air via both suction openings 2, 2 '.
- the filter means 10 is further arranged in the seat itself and has an activated carbon filter 15 and a pre-filter 17 upstream in the flow direction.
- the effluent from the blowers 8 and 9 air passes first the pre-filter 17 and then the ' activated carbon filter 15 and then purified from the seat 1 to flow outward.
- Corresponding air outlet openings are provided in the rear part of the fastening area 12, but not shown.
- the arrows b indicate how the air in the two-sided cavity parts 5, 6 reaches the bubbles 8, 9 and flows through them and enters the interconnected cavity parts 5, 6 and flows outward via the filter means 10.
- the part of the seat receiving the filter medium is provided with air outlet openings in the flow direction behind the filter. This part of the seat also has a lid so that the filter medium is easily replaceable.
- FIG. 2 shows a sectional view taken along the line BB of Figure 1, wherein in the left and the right half of Figure 2 different embodiments are shown.
- a toilet seat 1 In a toilet seat 1, only one or the other embodiment will be selected as a rule, so that on both sides of the longitudinal center line A the same design is selected. However, to explain various embodiments, FIG. 2 has been divided accordingly.
- the slot-shaped suction opening 2 ' is arranged in the bowl-side side wall 7 of the seat. The air thus enters the cavity 5 of the seat 1 laterally. It is shown how the seat 1 rests on an only hinted- bowl edge 20 of a toilet.
- the slot-shaped opening 2 ' may be a single elongated opening or may be divided into a plurality of elongated openings.
- the opening width d of the suction may be the same over the entire length of the slot or may be along the same Modify- •.
- the opening width of the slot in the front region 5 'of the cavity may be smaller than in the rear, attachment-side region 5.
- another embodiment is shown in which the one elongated suction port or at most a plurality of elongated suction ports on the The opening width d along the slot is preferably different for the lower-side intake opening 2.
- the opening width corresponds to the change in the cross-section of the cavity 6, so that in this embodiment too, preferably a small opening width in the region of the closed end 6 'of the cavity results and a larger opening width in the rear, attachment-side area 6 "of the cavity 6.
- the opening width of the slot can continuously from a small opening width in the front area to a larger opening width increase in the attachment side area.
- Figure 3 shows the embodiment with suction on the underside of the seat 1 in view of the seat from below.
- a suction port 2 ' is shown as an elongated slot with increasing opening width.
- the slot could also be formed by a plurality of elongated slots, so that a web 22 would be provided along the slot.
- the embodiment shown in the right half of the slot opening corresponds substantially to the boundaries of the cavity, so that it has a corresponding to the slot width changing cross-sectional area.
- an elongated slot-shaped suction opening 2 is shown, which, apart from its front area, has a substantially constant opening width. With a broken line, the cavity part ⁇ is further indicated, which in this case has a cross-sectional area which does not correspond to the attachment area with the opening width of the slot 2.
