Odour Free Toilet System

Abstract

An odour free toilet system comprises a vent head having an inlet which is magnetically attached to a toilet bowl. The inlet is positioned under a toilet seat and a toilet lid in between a pair of mounting assemblies for mounting the toilet seat and the toilet lid. The vent head is positioned behind the toilet seat and the toilet lid. The vent head having the inlet is out of the way of the toilet seat and the toilet lid in any position of the toilet seat and the toilet lid. The odour free toilet system further comprises an outlet fitting in the rear part of the top surface of the toilet bowl with the vent head covering the outlet fitting. A suction fan and plumbing provides air suction to the outlet fitting thereby providing air suction to the inlet close to the source of toilet odours.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] The following descriptions describe the preferred embodiments of the invention by way of example only.

[0022] FIG. 1 shows an exploded view of an odour free toilet system 100. A toilet bowl 102 has a top surface defining a pair of mounting holes 122a, 122b for mounting a toilet seat 124a and a toilet lid 124b. A plate 106 made of a ferromagnetic material such as iron, nickel and cobalt, is adhesively secured to the top surface of the toilet bowl 102 in between the pair of mounting holes 122a, 122b. A vent head 104 having an inlet 108 further comprising at least one magnet is magnetically attached to the plate 106 as will be further explained in the hereinafter. The top surface of toilet bowl 102 further defines an outlet hole 110 for receiving an outlet fitting 112. An outlet hose 114 has on one end an outlet hose fitting 114a and on the other end an outlet hose fitting 114b. The outlet hose fitting 114a matches the outlet fitting 112 at the bottom end thereof, thereby securing the outlet fitting 112 in the outlet hole 110. The outlet hose fitting 114b matches a fitting 118 of a pipe 116 connected to a suction fan 120 such as a common TT 100 vent having an input rating of about 187 cubic meter per hour (about 110 cubic feet per minute) mounted in a bathroom ceiling. The fitting 118 can be a wall fitting, the pipe 116 can be concealed partly in the bathroom wall and partly in the bathroom wall ceiling. The vent head 104 covers the outlet fitting 112 so that inlet 108 provides air suction to the toilet bowl 102 for disposal of toilet odours out of a roof vent (not shown).

[0023] Advantageously, air suction is provided close to the source of toilet odours.

[0024] Preferably, the vent head 104 having the inlet 108 forms a substantially symmetrical T-shape so that the outlet hole 110 and the outlet fitting 112 can be placed on either side of the toilet bowl 102.

[0025] Preferably, the plate 106 has a thickness ranging from about 1/16 of an inch (1.5 mm) to about 1/8 of an inch (3 mm).

[0026] FIG. 2 shows a top view of the vent head 104 having the inlet 108.

[0027] Preferably, the vent head 104 having the inlet 108 is made of a polymeric material.

[0028] The vent head 104 has a width Wh, a depth Dh, and a height Hh. The inlet 108 has a width Wi, a depth Di, and a height Hi.

[0029] Preferably, the vent head 104 has the width Wh of about 190 mm (7.5 inches), the depth Dh of about 39 mm (1.5 inches) and the height Hh of about 18 mm (0.7 inches).

[0030] Preferably, the inlet 108 has the width Wi of about 86 mm (3.4 inches), the depth Di of about 72 mm (2.8 inches), and the height Hi of about 9 mm (0.35 inches).

[0031] FIG. 3 shows a bottom view of the vent head 104 having the inlet 108. At least one magnet is required to attach the vent head 104 having the inlet 108 to the plate 106. Shown are three magnets 302a, 302b, 302c secured to the vent head 104 having the inlet 108.

[0032] Advantageously, the vent head 104 having the inlet 108 can be manually removed without tools for cleaning purposes.

[0033] Preferably, the vent head 104 having the inlet 108 further comprises a bottom gasket 304 for sealingly engaging the bottom of the vent head 104 having the inlet 108 to the top surface in the rear of the toilet bowl 102 when the vent head 104 having the inlet 108 is magnetically attached to the plate 106.

[0034] Preferably the bottom gasket 304 is made of a soft polymeric material.

[0035] FIG. 4 shows the toilet bowl 102 with both toilet seat 124a and toilet lid 124b in an up position. The inlet 108 fits under the toilet seat 124a and the toilet lid 124b between the mounting assemblies 402a, 402b of the toilet seat 124a and the toilet lid 124b. The vent head 104 is hidden from view behind the toilet seat 124a and the toilet lid 124b. The inlet 108 is set back a predetermined distance D from the rim 404 of the toilet bowl 102.

[0036] Preferably, the predetermined distance D ranges from about 15 mm (0.6 inches to about 25 mm (1 inch).

[0037] FIG. 5 shows the toilet bowl 102 with both toilet seat 124a and toilet lid 124b in a down position. The vent head 104 is rearwardly of the toilet seat 124a and the toilet lid 124b. The inlet 108 is hidden from view under the toilet seat 124a and the toilet lid 124b.

[0038] FIG. 6 shows the toilet bowl 102 with the toilet seat 124a in a down position and the toilet lid 124b in an up position. Both the vent head 104 and the inlet 108 are hidden from view, the toilet seat 124a in the down position hides the inlet 108 from view and the toilet lid 124b in the up position hides the vent head 104 from view.

[0039] The vent head 104 having the inlet 108 is out of the way of the toilet seat 124a and the toilet lid 124b in any position of the toilet seat 124a and the toilet lid 124b.

[0040] Advantageously, the vent head 104 having the inlet 108 are unobtrusive in actual use, hidden from view in most positions of the toilet seat 124a and the toilet lid 124b.

[0041] Preferably, the outlet fitting 112, the outlet hose 114, the outlet hose fittings 114a, 114b, the pipe 116, the fitting 118, and the side inlet 706 are 1 inch (25.4 mm) plumbing parts.

[0042] Advantageously, the odour free toilet system 100 allows for any hazardous electrical items to be placed remotely from a user of the odour free toilet system 100.

[0043] A person skilled in the art will have by now appreciated the full scope of the invention. In particular, the scope of the invention is not limited to the preferred embodiments described by way of example in the above.
