Abstract

At the end it is very inexpensive. The yearly cost is only 3 dollars per year.

Description

BACKGROUND OF THE INVENTION

It has been about six years since I have moved to my new apartment and from the start I had a big problem with moisture, mold and cold temperature in both of my bathrooms. I have used electric heater which solved part of a problem, but it did not enhance a quality of an air. So I have started to think what can I do to remedy this problem.

SUMMARY OF THE INVENTION

That is how I have thought out this idea. It does solve a problem with high humidity, moisture, removes cold temperature in the winter, and creates healthy condition. It is making the air in a bathroom healthy and fresh. You should always keep the door to a bathroom closed and keep the germs inside. I saw in so many condominiums and houses that a kitchen is so close to a full bathroom or a powder room. My idea improves these conditions, so you can keep bathroom doors closed all the time.

DESCRIPTION OF THE DRAWINGS

My fan (FIG. 1) is running all year long and at the same time supplying dry, warm air to a bathroom. For the installation of my new fan I have used parts; flexible metal conduit FMC squeeze connector

(FIG. 2), which is screw in to a rigid Type C conduit body

(FIG. 3). Then metallic armored steel flexible conduit

(FIG. 4) is screw in to the flexible metal conduit FMC squeeze connector. The three wires from metallic armored steel flexible conduit are connected in an electrical 1900 box, black one to fan speed controller, white to the neutral wire, and green to the body of an electrical 1900 box (FIG. 5).

DESCRIPTION OF THE INVENTION

The fan is installed above a bathroom door, in a wall, and “pumps” inside a bathroom an air which accumulates close to a ceiling. This makes a moisture and water around a bathtub disappear fast. My fan, which is installed in a Master Bathroom, is so quiet (19 decibels) that I can sleep without a problem. The original fan which is installed when a house or a condo is built “pumps” the air from bathroom to a chimney, but when I was taking a shower my mirror was fogged always in a matter of minutes. With my new fan which “pumps” a fresh, warm and dry air 50 cfm (cubic feet a minute) to a bathroom and the original around 60 cfm to a chimney, the air circulates 100% and you will never have a fogged mirror and a part of a moisture escapes from a bathroom in a few minutes. Because of all of this a mold is not growing inside a bathroom. For example, one of my bathrooms is around 350 cubic feet and the total time for 100% exchange of air would take only seven minutes. The installation of my idea, for a professional electrician, is easy and it takes around half a day. My Axial fan is 115 Volts AC, 4W, 50/60 Hz with the maximum speed 1450 rpm a minute. The noise is 19 db, “pumping” 50 CFM of air. The warranty is 70,000 Hr, the fan has ball bearings, and the cost of running the fan non-stop 24/7 days per year is less then 3 dollars. I am protecting my whole electrical circuit with time-delay ¼ Amp, 115 VAC fuse and I am adding fan speed slider switch (115 VAC) to control the rpm from Off position to maximum speed 1450 rpm. The dimension of the fan is 4¾″×4¾″, and the thickness is 1½″, and the added parts (placed outside the fan) “Fan Guards” are 7¼″×6¼″.

Claims

1. My HEATING AND VENTILATION IN BATHROOM system solves problems which occur in every bathroom or any space with a lot of moisture, it eliminates mold and mildew, supplies dry, warm air, is cost effective (˜3 dollars per year), consists of just few element such as;

Axial fan, fan guard, flexible armored steel conduit, flexible metal conduit (FMC), Rigid Type C conduit body, fuse holder case, AMP fuse, fan speed control, or Single-Pole switch ON and OFF.

2. The surprisingly quiet Axial fan, installed permanently over a door, is running non-stop, and its electrical wires are connected to Rigid Type C conduit body.

3. The metallic armored steel flexible conduit with three wires Hot (L1), Neutral (N), Ground (G) are connected inside Rigid Type C and placed inside an electrical box (1900) on the other end.

4. Inside the electrical box the L1 wire is connected to fan's speed control slider switch, neutral wire to the neutral wire and ground (green) to a ground wire.

5. The main power L1 is connected to a fuse holder and from the fuse to fan's speed control slider switch.

6. The whole electrical wiring and components are protected by time-delay ¼ AMP, 115 VAC fuse which is located in the fuse holder case.

7. My idea improves positively air condition in a bathroom and when a chimney and axial fans run together the air recirculates 100% in 7 minutes (for example in 350 cubic feet bathroom), and mirror would never get foggy.
