Description

SYSTEM AND METHOD OF ASSEMBLY OF AUTOMATIC DEODORIZER FOR TOILETS

Object of the invention

The present invention consists of a system and method of assembly for the extraction of odors from a toilet that works automatically using a proximity detection system. The system comprises a nozzle preferably made of silicone or in any material that is hygienic and easy to clean, comprising a structure adapted to aspirate a large amount of air and lead it to a fan device that evacuates the gases into a filter so that the air returns to the environment without any residue, which causes a bad smell.

Field of the Invention

The present invention has its application within the field of toilet manufacturing and specifically to the industry dedicated to providing innovative solutions in the bathroom and interior design industry.

Background of the invention

The presence of unpleasant odors is a problem that occurs in industrial, commercial and residential environments. To solve the problem, extraction systems with fans, ducts and others have been adapted to replace the contaminated air. However, this problem is more difficult to address when it comes to enclosed spaces, such as public or private bathrooms. The use of natural ventilation is not the best solution because it turns out to be very slow and sometimes odors can spread in other spaces, which is annoying for people.

In practice, different systems have been implemented to eliminate smells. A first way is to place a ventilation equipment in the installation so that it absorbs the air in the bathroom and replaces it with clean air. However, this system has the disadvantage that when it is necessary to replace a large volume of air, an equally large ventilation equipment is required, which implies greater power consumption and greater noise production.

Another quite popular system is the use of air fresheners that mask bad odors through chemical fragrances. In this case, for the system to produce the proper effect, a large amount of chemical agent is required, which is usually not economical.

Some toilets have extraction systems incorporated in the lid, in the seat or in the same body of the toilet, which conduct the gases directly from the rate of the toilet to the ventilation system or to some type of filter. However, this type of system is expensive since the construction of the toilet is complex and often bulky, or in the case of a conventional toilet, modifications involving usually expensive mechanisms are required.

As can be seen, there is a need for a system that avoids the above inconveniences, that has an adequate, effective efficiency and that can be used in any type of toilet without the need for a permanent installation to eliminate odors from bathrooms effectively, Economical and fast.

Description of the invention

To solve the above problems, the present invention teaches a deodorizer assembly system and method for use in bathrooms that eliminates unpleasant odors from the toilet. The deodorizer has a system of infrared sensors that activate it automatically every time a user makes use of the bathroom. On the other hand, the developed system can be installed in any standard toilet, which makes it a highly versatile appliance since no adaptation or change of sanitary work is necessary.

The deodorizer assembly system and method comprises an extraction nozzle which adapts to the shape of the toilet flange, a system of channels for conducting the extracted gases, a fan that produces the extraction force, and an outlet pipe for Bring the gases to a filter.

The main contribution of the present invention is in the structure developed for the extraction nozzle. This nozzle is designed so that it has a wide area for the collection of gases and a smaller area for their exit. Following the nozzle, a reduction box is connected which contains the system fan, this fan sucks the air and sends it to the ventilation ducts of the installation, an insulating gasket completes the hermetic seal of the device.

In the event that ventilation ducts are not available, the invention provides for the use of an activated carbon filter, silica gel, potassium permanganate and sodium bicarbonate, which absorbs odors once the contaminated air passes through it .

In this way, the system developed is not only a fairly versatile system, but it is also a system of easy installation, removal and cleaning, which makes it ideal for use in public, private and even portable toilets.

Detailed Description of the Preferred Modalities.

The system and method of assembly of the odor extractor deodorizer of the present invention is designed so that it can be adapted to any type of toilet since the constituent parts thereof can be adapted to the structure of conventional toilets, preferably in the space comprised between the biscuit and the porcelain of the toilet.

Figure 1 specifies the general structure of the implemented system. In this case, a vacuum or odor suction nozzle (2) is located on the toilet (1). The nozzle (2) has a flattened structure that allows it to be located on the edge of the toilet in the space established between the biscuit and the porcelain. In this location, the nozzle is not in contact with any type of matter or fluid, but it can aspirate the rising gas. The nozzle structure will be explained later. The gases aspirated by the nozzle are conducted through a conduit (4) to a cover housing of the extractor element (3). This extractor element comprises a reduction box inside which a motor-fan is located which is responsible for providing the necessary impulse to absorb the gases from the toilet. This device is fed directly from the mains through a connection cable (7). At the outlet of the extractor, a filter (5) composed of activated carbon, silica gel, potassium permanganate and granulated sodium bicarbonate (21) is coupled to remove gases. Figure 2 shows the location of the extractor nozzle (2). The extractor device is located on the flange of the toilet towards the back. In the upper part of the cover housing of the extractor element (3) there is an infrared sensor (2 A) which sends the activation signal to the motor-fan once the user approaches the toilet. Both the nozzle and the pipe (4) are imperceptible to the user which are left behind the toilet lid (8).

The structure of the gas suction nozzle (2) is specified in Figure 3. The suction nozzle (2) comprises a clamping plate (9) which has a semi triangular shape, with a curved flange on the front , arranged to engage the inner flange of the porcelain of the toilet. The main suction structure (10) is located on the clamping plate (9), which basically consists of a structure to channel the sucked gases into a plurality of inlet holes (12) and lead them to an outlet hole (11) . This structure allows to quickly drive the sucked gases towards the fan.

The inlet holes (12) are arranged on the curved face perpendicular to the toilet. There may be one or more entry holes, preferably a sufficient amount of holes to cover the entire curved surface. The exit hole is arranged on the opposite side of the curved face. The diameter of this hole must be adapted to fit the inlet pipe (4). On the clamping plate (9) there are holes (13) arranged to couple the toilet plate on the screws that hold the cupcake and the toilet lid.

Figure 4 specifies the suction piece (10). This piece consists of a base on which two symmetrical triangular profiles (14) are mounted. The profiles (14) form a funnel-shaped path so that the captured gases are channeled through a channel (15). The output of this channel is coupled to the output hole (11).

An alternate mode for the suction nozzle (2) is shown in Figure 5. In this case, the profile of the support plate (10) is modified so that it has a lower probability of contact with residues, and the holes (13) are replaced by a pair of slots (16) which gives greater versatility when it comes to Install the device. The figure also shows the cover (16A) that seals the suction piece (10).

The cover housing of the extractor element (3) is shown in Figure 6. The box has an inlet pipe (20) which is coupled to the supply line (4). At the opposite end an outlet pipe is located towards the mixture of: activated carbon, silica gel, potassium permanganate and granulated sodium bicarbonate (21) to couple the sucked gases with the outlet pipe. The gases that come from the nozzle (2) are sucked by a fan (17), these pass through the inlet pipe (20) and when they leave the pipe they expand into a first cone (18). The fan (17) drives the gases into a container housing a filter (5) containing activated carbon, silica gel, potassium permanganate and sodium bicarbonate (NaHC03) granules (21). The system is hermetically sealed and adjusted by support means such as through screws (22).

Figure 7 shows a front view of the cover housing of the extractor element (3) where the transverse arrangement of the fan blades (23) is noted (17). Figure 8 shows the structure of the cone (18). This piece can preferably be constructed in a plastic material and is formed from a square base (25) on which the conical structure is located. A hole (24) is made on the cone which is arranged to couple the pipe (20).

The sucked gases are passed through an activated carbon filter, silica gel, potassium permanganate and granulated sodium bicarbonate. The cover housing of the extractor element (3) comprises inside a replacement cartridge (26) of granulated material which requires a replacement every two months or according to the amount of discharges approx. Every 3000 discharges as shown in the Figure 8, which is coupled to the outlet side of the reduction box. The container comprises a generally threaded nozzle (28) to engage with a lid (32) explained below. At the other end of the replacement cartridge (26) a mesh (27) is made which is arranged to be released once it has been filtered by activated carbon, silica gel, potassium permanganate and sodium bicarbonate.

Inside the replacement cartridge (26) a retaining mesh (29) is located, figure 10. This mesh serves to retain the granulated material in a single portion of the container, leaving a free space for the gases to expand and pass by the filter in a slower way. The mesh (29) must have the same shape as the container.

Figure 11 shows a square gasket (30) used to hermetically fit the cover (32) of a replacement cartridge (26), with the cover housing of the extractor element (3). This package has a circular hole (31) whose size must match the diameter of the nozzle (28) of the container. Finally, the container lid (32) (figure 12) is formed from a support plate (35) having a mesh (33) in its central part. On the plate there is a support (34) on which the nozzle (28) of the container is coupled. The flat face of the plate (35) is coupled with the cover housing of the extractor element (3) by placing the square gasket (30) between the two pieces. The entire system is designed with their respective airtight gaskets to prevent gas from escaping. It is considered not necessary to make this description more extensive for a person skilled in the art to understand the scope and advantages of the invention. The materials, shape, size and arrangement of the elements will be susceptible to variation as long as this does not involve alteration in the essential form of the invention. All the technical and scientific terms used here have the same meaning as those of ordinary skill in the art understand them.
