Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is used for floor maintenance in buildings, and specifically, the wax applied to the floor (floor surface) is forcibly removed. The present invention relates to a floor dryer for drying.

[Conventional technology]

The floors of buildings are covered with various flooring materials such as resin tiles and artificial/natural stone, but in order to protect these flooring materials and maintain their beautiful appearance as glossy surfaces, it is necessary to It is necessary to apply wax to the floor surface.

Furthermore, since wax has the property of resisting stains, by repeatedly removing and reapplying it as appropriate, it also has the role of not directly staining the flooring material.

Floor wax is an emulsion containing solid content such as oils, fats, resins, and other chemicals, and the water content is 90%.
After applying it to the floor, it is dried and the coating is repeated to thicken the coating, but as mentioned above, wax has a high water content and does not dry quickly, and in addition, recently They tend to apply several layers of wax, which is mainly composed of resin solids, to create a durable wax layer, so it takes more time to wait for the wax to dry than to apply the wax. 6 In addition, since waxing work is generally done late at night, workers waste valuable late-night time without being able to move on to the next task. There was also the problem of putting it away.

Conventionally, drying was accelerated by running an electric fan close to the floor or by directing the outlet of a sirocco fan toward the floor, but simply blowing air is not sufficient. If you try to shorten the drying time by increasing the wind blowing on the floor,
There was a problem in that the surface of the applied wax became rippled, making it impossible to finish the floor surface smoothly.

[Problem to be solved by the invention]

It has long been well known that the most effective way to dry wax applied to a floor surface is with hot air. However, to date, no floor dryer that uses hot air has appeared. The main reason for this is that there is no suitable heat source that can safely supply a sufficient amount of hot air for moving work inside buildings and other structures.

The first possible heat source for obtaining hot air is one that uses oil (kerosene) or gas as fuel. However, using fire inside a building is extremely dangerous in terms of disaster prevention, and in particular, its use in moving equipment is strictly prohibited, making it unsuitable for drying wax.

The second possible heat source is electricity (heater), which is safe in terms of disaster prevention and sanitary.
The 00V outlet is 15A.

The maximum diameter is about 1.5 KW, and the power as a heater is extremely low, causing the problem that a sufficient drying effect cannot be achieved.

Therefore, the technical problem of the present invention is to provide a floor dryer that is highly safe as a fire source, can be used safely inside buildings, and is hygienic and exhibits excellent drying effects. .

[Means to solve the problem]

The measures taken in the present invention to solve the above technical problems are as follows.

(1) An air-cooled engine that uses propane gas as fuel is mounted on the truck, and the air-cooled engine is covered with a tunnel-shaped cover made of heat insulating material.

(2) Open the tip of the cover toward the floor.

(3) Attaching an axial fan to the base end of the cover that is rotated by the air-cooled engine and blows air toward the front end.

(4) A generator that generates electricity by being rotated by an air-cooled engine is attached to the trolley, and inside the cover,
Install a heater that generates heat by receiving power from the generator.

(5) A heater that receives electric power from the generator and generates heat is attached to the trolley so as to face the floor.

[Effect]

The above means works as follows.

■The elements mentioned in (1) above store the heat and exhaust gas (heat) emitted by the air-cooled engine inside a tunnel-shaped cover made of insulation material, and use this heat to dry the floor. On the other hand, since the engine burns inside the cylinder, it is highly safe as a fire source, and since the engine uses propane gas, it is contained in the exhaust gas. The amount of C○ is also small, making it possible to use it safely indoors.

(2) The elements described in (2) above make it possible to guide the heat of the engine and exhaust gas stored in the tunnel-shaped cover toward the floor surface through the cover.

■The element mentioned in (3) above uses the engine's radiant heat and exhaust gas heat stored in the cover to be blown onto the floor surface using an axial fan rotated by the engine, thereby shortening the wax applied to the floor surface. Allows time to dry.

■The factors mentioned in (4) above are that the generator can increase the amount of heat generated by the heater, and the heat generated by the heater generates even higher temperature hot air inside the cover, which is then blown onto the wax on the floor. This allows for a significant reduction in drying time.

(2) The element described in (5) above makes it possible to directly heat the floor surface to a high temperature with a heater to further enhance the drying effect.

As described above, the above-mentioned technical problem can be solved by the above-mentioned means, and the problems of the conventional technology can be solved.

The air cooling fan 6 indicates a cover made entirely in the shape of a tunnel to cover the periphery of the engine 4, and the engine 4 is housed in the interior 6S of the cover 6 provided on the truck 1. The air cooling fan 5 constitutes an axial fan that creates an air flow inside the cover 6.

The above-mentioned cover 6 is constructed using a heat insulating material with a reflective plate 6a stretched on the inner surface, and its tip opening 6T is opened slightly downward toward the floor surface, and the protective tube 7 provided at the plate end opening is opened slightly downward toward the floor surface. The above-mentioned fan 5 is housed inside, and when the fan 5 rotates, outside air is introduced into the cover 6 as shown by the arrow X to air-cool the engine 4, and the cooling heat and the engine 4 are
