Description

LOCAL WASTE AIR SUCTION DEVICE
DESCRIPTION OF THE INVENTION
Field of Technology
Suction; local suction of polluted air; removing unpleasant odours from the toilet bowl
Technical Problem
In sanitary facilities, air is often polluted and odours can be detected, spreading from sanitary installations, preferably from toilet bowls.
In the majority of known cases, air is discharged into the surrounding area through open windows or by using a fan. Ventilation of entire sanitary facilities is more durable and expensive, especially:
- in the winter period, when the facility needs to be heated and larger amounts of warm air are discharged into the surrounding area, and
- in the summer period, when the facility is cooled and larger amounts of cooled air are discharged into the surrounding area. The suction of waste air at the place of origin prevents waste air from spreading throughout the surrounding area or preferably around the entire sanitary facility where the toilet bowl is installed or even around adjacent facilities to which the odour is spreading. If local suction is used, a significantly lower amount of polluted air needs to be replaced.
The subject matter of the invention solves the problem of replacing polluted air by using a device for local waste air suction.
State of the Art
Rooms with polluted air can be ventilated in several ways: with natural ventilation, for example occasional opening of windows, which results in cold air entering the room, draughts, and a significant heat loss from the room in winter and significant heat ingress into the room in summer; with local or central forced ventilation devices, where polluted air is discharged with air suction devices, preferably with fans.
Known local air suction devices ventilate the entire room in which the source of pollution is installed. A larger quantity of already diluted polluted air is discharged from the room, which results in increased energy consumption for ventilation and a greater change in the temperature of the air that is heated or cooled in the room.
The problem of pollution is in many cases solved with various air fresheners which neutralise odour by chemical means.
There is no known device on the market, which would remove polluted air in the presented manner at the source of pollution with local suction of polluted air. Description of New Invention
The subject matter of the invention is a local waste air suction device which solves the technical problem of suction of polluted air at the point of pollution with the highest concentration of pollution and prevents the spread of polluted air into the surround air.
The local waste air suction device comprises at least one or more waste air suction points, at least one connecting outlet pipe, a fan and at least one fan power switch.
The local waste air suction device can be used for any purpose, but preferably it is intended for extracting odours from the toilet bowl.
New toilet bowls can be constructed in such a way that they are already equipped with individual parts of the local waste air suction device, i.e. waste air suction points.
A suitable overlay comprising individual parts of the local waste air suction device is attached to the existing toilet bowls. The overlay can also be mounted on new toilet bowls which do not comprise individual components of the local waste air suction device.
New toilet bowls are equipped with at least one, but preferably more waste air suction points, whereas individual components of the local waste air suction device are integrated in the toilet bowl. In this case, waste air suction points are preferably fitted behind the upper inside edge where the water inlet into the toilet bowl is also positioned. The fan for extracting waste air is mounted slightly higher than the water inlet into the toilet bowl in order to prevent the water intake into the connecting outlet pipes for extracting waste air or, consequently, into the fan. Even if water is supplied into the local waste air suction device during its operation, water is returned into the toilet bowl after the fan is turned off. Waste air suction points can be positioned also on the visible inside edge of the toilet bowl. If an overlay is used in case individual components of the local waste air suction device are not integrated in the toilet bowl, the waste air suction points are preferably positioned on the visible inside edge of the toilet bowl or the lower edge of the overlay.
Waste air suction points are positioned in such a way to allow that waste air is captures as efficiently as possible, preferably on the interior side of the upper edge of the toilet bowl, whereby the position of the waste air suction points is limited by the water level in the toilet bowl on the lower side and by the person sitting on the toilet bowl on the upper side.
If an overlay is used, when air flows through the waste air suction points, waste air is collected in a flow manifold which is positioned inside a specially designed ventilation overlay which is attached to the toilet bowl.
The polluted air captured by the waste air suction points travels through one or more connecting outlet pipes, preferably through two connecting outlet pipes which are preferably joined into one duct through which the fan sucks the waste air into the surrounding area. One or more connecting outlet pipes are connected with the fan through a fan connector. The fan pushes the waste air into the surrounding area through the outlet pipe running from the fan.
The suction of waste air at the place of origin prevents waste air from spreading throughout the surrounding area or preferably around the entire sanitary facility where the toilet bowl is installed or even from the surrounding area of the sanitary facility.
The fan is turned on when the user is making a bowel movement on the toilet bowl. The fan power switch van be constructed in any way, but preferably the switch is turned on manually and is preferably installed in the immediate vicinity of the toilet bowl. The fan power switch may also be constructed in the form of a sensor, a push switch under the toilet seat, a light switch or in any other form. Waste water and excrements or waste go exit the toilet bowl through the outlet pipe. Water flows into the toilet bowl through the water inlet into the toilet bowl.
If a toilet bowl equipped with integrated individual components of the local waste air suction device is used, the waste air flows out of the toilet bowl and the inlet water flows into the toilet bowl through the connectors which are attached to the connecting surface on the toilet bowl.
If a toilet bowl which is not equipped with integrated individual components of the local waste air suction device is used, the waste air flows through the connectors which are connected to the overlay, whereas the inlet water supplied to the toilet bowl is connected directly to the toilet bowl.
New toilet bowls which comprise a part of the local waste air suction device are slightly thicker than standard toilet bowls on the back, where water and air connectors are positioned, in order to allow enough space for attaching one water pipe from the toilet flush and preferably two connecting outlet pipes, preferably made of PVC material, whereby the connecting outlet pipes may be rigid or preferably flexible.
The dimensions of the connecting surface of the toilet bowl are preferably approximately 250 mm x 80 mm. The diameter of the connecting outlet pipes is preferably 40-50 mm.
A single connecting outlet pipe, preferably with a diameter of 80-100 mm, can be connected to the toilet bowl through the outlet pipe connector. The use of a single connecting outlet pipe results in an uneven suction of air from the toilet bowl and mechanical weakening of the toilet bowl, which is why it is preferable to use two connecting outlet pipes which are attached to the fan and joined into one pipe through the fan connector. The fan connector can have any shape, but preferably it is formed in a trouser shape, with two connectors at an angle or with two direct inlets, their axis being parallel to the axis of the fan connector. In order to simplify the construction and lower the costs of pipes, the local waste air suction device is preferably equipped with pipes of circular cross-section.
To ensure greater stability, the fan is preferably of a tubular design and is preferably mounted on or in the wall through which the connecting outlet pipes are routed.
The old toilet bowl does not need to be replaced with a new one in order to use the local waste air suction device. A suitable overlay is attached to the toilet bowl, having several waste air suction points on the inside of the perimeter or on the underside, through which the waste air is sucked out of the toilet bowl into a hollow overlay from which preferably two connecting outlet pipes are routed and connected to a fan that blows waste air into the surrounding area.
In apartment buildings and tower blocks the waste air is discharged into the ventilation duct and then into the surrounding area. The overlay is mounted on the toilet bowl in any way, but preferably it is mounted with fixing plugs, double-sided glue or silicone. The overflow and the fan can also be connected with one thicker connecting outlet pipe; however, in this case, there must be fewer waste air suction points in order to improve the distribution of waste air or the cross-sections of the waste air suction points must be smaller so that the air is sucked out around the entire perimeter of the overlay.
The essence of the invention is further explained below with the description of embodiments and attached figures, whereby the figures are part of this patent application and show the following:
