Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a configuration in which a heater is disposed in a vacuum cleaner that discharges exhaust air downward and moves its main body floating to clean the vacuum cleaner.

Prior Art Conventionally, this type of vacuum cleaner was manufactured using Utility Model Application No. 51-140578
The configuration shown in the publication was common.

The configuration will be explained below based on the drawings.

In Fig. 4, 1 is a vacuum cleaner main body (hereinafter referred to as the main body) that has a built-in electric blower 2, dust collection bag 3, etc. The problem that the invention aims to solve is when cleaning with such a conventional vacuum cleaner. The main body 11 is routed by pulling the hose connected to the main body 1, but its function is simply to suck in dirt from the floor.

In recent years, there has been a trend toward sealing house structures or deep cleaning, and many homes meet the habitat conditions for dust mites, causing them to breed and have a negative impact on our lives.However, vacuum cleaners simply suck up dust mites. Also, the dust mites hiding inside the tatami mats and deep inside the carpet were impossible to inhale.

The present invention solves these conventional problems and makes it possible to exterminate mites at the same time as cleaning.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention includes an exhaust port for discharging the exhaust air from the motor fan to the bottom surface of the main body, and a skirt portion protruding from the bottom surface on the outer periphery of the main body. This configuration includes a heater and a retaining plate that holds and covers the heater, and a thermoprotector is disposed between the bottom surface of the main body and the retaining plate.

Effect of the present invention With the above-described configuration, the exhaust air is covered by the skirt portion, the exhaust pressure is increased, and the main body is lifted off the floor to be movable for cleaning, and the exhaust air is heated with a heater. By blowing hot air from the floor opening, it is designed to kill dust mites hiding on the surface and deep inside of tatami mats and carpets.

In other words, it has a cleaning and acaricidal effect.

In addition, hot air is said to be the best condition for killing mites, and
Almost 100% when hot air is applied for 3 seconds at ℃ and 1 second at 70℃
There is an experimental result that can kill, and the temperature setting of hot air is 6.
The thermo protector operates and turns off the heater when the temperature exceeds 0°C to 70°C, so there is no thermal deformation of the main unit or floor surface, making it highly safe and suitable for use with floor-moving vacuum cleaners. It can be expected to have a mite-killing effect.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings.

1 to 3, 10 is the main body of the vacuum cleaner, and this main body 1o has a dust collection chamber 12 in which a dust collection bag 11 is removably built in on the front side, and a motor fan 13 in the rear side. The motor chamber 14 is arranged in the upper part of the main body 162 and the lower part of the main body 16. It consists of a dust lid 17.

A handle 18 is provided at the front of the main body 10 and is used when carrying the main body 1o. 19 is a suction port to which a hose is connected.

Reference numeral 20 denotes an exhaust port disposed at the lower part of the motor chamber 14, and the exhaust air from the motor fan 13 is guided to the exhaust port 20 through an exhaust passage 21 as shown by the arrow, and is discharged to the outside of the main body 10.

Reference numeral 22 denotes a skirt portion which is wound around the outer periphery of the main body 1o and is formed to protrude downward from the bottom surface of the main body 1o, and its lower end has a smooth rounded shape and comes into close contact with the floor surface.

That is, the exhaust air is surrounded by this skirt portion 22.

Reference numeral 23 denotes a heater disposed below the exhaust port 20 in the skirt portion 22, and is covered evenly with the lower part of the unit portion 22 so as not to be touched so as to facilitate support.

The type of heater is not particularly specified as long as it is highly safe and resistant to vibration.

The heater 23 can be turned off or turned off by a switch 24 placed at the top of the main body 1o.When turned on and off together with a switch 25 for the motor fan placed next to it, the exhaust air from the motor fan 13 is heated and the hot air is turned off. It is designed to be sprayed onto the floor.

The conditions for killing mites are as mentioned above: 6Q°C for 5 seconds;
There is an experimental result that applying hot air at 60°C for 3 seconds and at 70°C for 1 second can kill approximately 1oO%, and the temperature of the exhaust air after passing through the heater 23 is set at 50°C to eo'c.
If set at a certain level, even a floor-moving type vacuum cleaner can be expected to have a sufficient mite-killing effect without causing abnormalities such as thermal deformation on the main body 1Q or the floor surface.

In addition, since the exhaust air from the motor fan 13 cools the motor fan 13, it is heated to 20 to 30 degrees.
The temperature is rising, and only a small amount of heating by the heater 23 is required, and a small, small-capacity motor may be installed.

27 is a thermo protector disposed between the lower surface of the main body 10 and the holding plate 2e, and a thermo protector 27 is arranged between the lower surface of the main body 10 and the holding plate 2e, and
When there is a person in the room, the heater 23 is automatically turned off so that the temperature of the exhaust air blown onto the floor does not rise above the above-mentioned setting. This is to prevent abnormalities such as deformation. The thermo protector 27 is arranged and connected between the motor fan 13 and the heater 23 which are wired in parallel. 2
8 is a power source.

In addition, the air volume of a general household vacuum cleaner is approximately 1. The degree of vacuum with noodle flour is approximately 1600IIiM flame column, and even considering the exhaust pressure loss, it is calculated that a pressure of more than 10ooWIM flame column will be added to 1 cr/I, and when multiplied by the projected area of the skirt part 22, it will be approximately 5A9 electric vacuum cleaner. The machine floats sufficiently, and the main body 10 can be routed without any problems.

Effects of the Invention As described above, the present invention includes an exhaust port on the bottom surface of the main body and a skirt portion that protrudes downward from the bottom surface and is provided around the entire circumference.
The heater and thermo protector are placed inside the skirt, the heater is held by a holding plate, the thermo protector (a holding plate is also available) is held under the main body, and the structure is covered by the holding plate. When in use, the main body floats due to exhaust pressure. This also prevents the dust on the floor from scattering.

The heat generated by the exhaust air is controlled by a thermoprotector so that the temperature is around 60℃, and the hot air is blown onto the tatami or carpet surface, which can kill dust mites hidden on the surface or deep inside. It kills mites while cleaning, prevents negative effects on the human body, and allows people to live a healthy life.

In addition, the above method can dry the floor surface and kill mites.

It has great practical value as it can prevent the occurrence of mites and even mold.

Furthermore, the heater is placed on the skirt outside of the main unit, and is controlled by a thermo protector so that the temperature of the exhaust air is around 60°C, so the main unit and floor surface will not be thermally deformed or burnt out, making it safe. The quality is high.
