...We have seen the completion of the present invention.

In other words, the present invention sprays water in a vacuum cleaner container to form a large amount of fine water droplets, and sends air containing these fine water droplets into a room, while also removing dust and bacteria in the same room. The contaminated air is sucked into the container, brought into contact with fine water droplets to remove dust and bacteria, and the mixture of purified air and fine water droplets is sent into the room, repeating this cycle. This is a completely new type of vacuum cleaner, which was previously unknown, and which combines the functions of a normal vacuum cleaner and an air conditioner.

〔Example〕

While referring to the accompanying drawings, the functions and effects of Structure 1 of the present invention are as follows:
This will be explained in more detail with reference to the following examples.

Example 1 Please refer to FIG. 1 in the figure represents the entire vacuum cleaner,
A hose 50 is connected to the dirty air inlet pipe 8.

The hose 50 is provided with a flexible portion 51 and a distal end portion 52 so that the distal end portion of the hose can move freely. A filter 53 is fixedly or detachably mounted inside the hose, and a container 54 for storing coarse dust is fixedly or detachably mounted. Casters 55 are detachably attached so that the vacuum cleaner 1 can be moved freely.

Reference numeral 6 denotes a container for spraying water to form a large amount of fine water droplets, and serves as a dust removal and sterilization cyclone. In the upper part of the cylindrical part 31 of this container, that is, the cyclone 6, a dirty air pocket 32 is provided in the direction of contact. An outlet f11 is provided at the center of the cylindrical portion 31 and extends downward from above.

A water injection pipe 12 is connected to the outlet pipe 11 coaxially with the outlet pipe 11.
are arranged around. The injection pipe 12 has an injection nozzle 1
6 are provided in large numbers.

A fan 6 is arranged above the outlet pipe 11 to suck air inside the outlet pipe 11 and promote the flow of air.

A water tank 5 and a pump 17 are provided at the end of the conical portion 66 of the cyclone 3.

Therefore, water flows in the direction of arrow B, i.e. 1. +? The water is circulated in the following order: pump 17 → water supply pipe 14 → injection pipe 12 → cyclone 30 cylindrical part 61 → its conical part 56 → water tank 5 → filtration device 16 → pump 17.

Reference numeral 4 denotes an air circulation chamber, which is arranged around the outer periphery of the cyclone 3. In the drawing, the outlet pipe 11 of the cyclone 5
An annular air passage 15 is arranged between the chamber 4 and the cyclone 6 for conveying the air discharged from the chamber downward. Furthermore, the annular air passage 15 and the chamber 4 are separated by a wall 2.

A 77 tube 34 is attached to the chamber 4 as needed to help send clean air into the chamber. 28 is a pulp for replacing the water in the water tank 5. Further, if necessary, the water tank 5 may be made into a cassette type and made removable. Arrows indicate the direction of air flow, and arrow B indicates the direction of water flow.

Next, the functions and effects of this vacuum cleaner 1 will be explained.

Start driving the vacuum cleaner 1 by rotating the 77 cylinder 6 (and 34 if necessary), touch the hose tip 52 to a dirty area, and operate it in the same way as a normal vacuum cleaner.
Vacuum air and/or dirty areas are sucked in with the air. Large-sized dust is captured by the filter 53 and collected in the container 54. The air from which large dust has been filtered passes through the hose 50 according to the arrow, enters the inlet pipe 8, enters the inlet 62, and is sucked into the container 3 consisting of a cyclone. The air sucked in this way is transferred from the water injection nozzle 16 to the cylindrical part 61.
It comes in contact with and mixes with fine water droplets generated by spraying or jetting on the wall of the container, exchanges heat, and is completely cleaned by removing bacteria and bacteria.

The thus purified air (for example, about 7° C., temperature about 1001 °C) is discharged from the outlet pipe 11.

The flow of the air thus sent out is promoted by the action of the fan 6, and is sent into the annular air passage 15, where it flows downward. Not only is the air purified in Cyclone 3;

Of course, the temperature is controlled by the temperature of the water being sprayed. The air that has proceeded downward through the annular ventilation passage 15 enters the chamber 4 through a communication passage 21 bored at the bottom thereof. The connection wr21 is formed by cutting out the lower end of the cylindrical wall 2. The air that has entered the chamber 4 is discharged into the room through a nine air discharge pipe 22. In this way, the dirty air and dirty parts of the room can be strongly suctioned, not only dust removed but also sterilized, and the purified air returned to the room.

Example 26 In the vacuum cleaner of Example 1, from the container, ie the cyclone 3, the outlet pipe 11. Clean air is discharged into the room through the annular air passage 15 and the chamber 4, but this clean air is mixed with fine water droplets.

The room may become wet or overly humid.

Most of these phenomena can be prevented by causing water to collide with the wall of the cylindrical portion 61 at a higher speed from a water jet nozzle to form ultra-fine water droplets.

However, using a method different from this method,
Alternatively, this embodiment is an embodiment of a vacuum cleaner for efficiently dehumidifying humid air in order to further enhance the dehumidifying effect.

That is, this embodiment relates to another type of vacuum cleaner of the present invention, which is the same as the vacuum cleaner of embodiment 1 described with reference to FIG. 1. Please refer to Fig. 2, which relates to a completely new high-performance vacuum cleaner that has both cleaning and indoor air conditioning functions. In this embodiment, by adding a refrigerator R and effectively utilizing the heating and cooling system in the refrigeration cycle, it is possible to dehumidify the air discharged in the first embodiment and also to control the temperature at the same time. This is an improved vacuum cleaner. (Note that in FIG. 2, in order to simplify the drawing, only the parts that are different from FIG. 1 are given reference numbers, and the valve 2B is not shown.) Container,
That is, the refrigerator R is installed on the inner wall of the cylindrical portion 31 of the cyclone 3.
The evaporation tube 60 is arranged in a spiral shape or other suitable shape. The positional relationship between the evaporation pipe 30 and the injection nozzle 13 is arranged such that the water from the injection nozzle 15 is sprayed or sprayed onto the evaporation pipe 30. The sprayed or injected water comes into contact with the evaporation tube 30 through which the refrigerant passes and is cooled, and the air entering from the inlet 8 also passes through the evaporation tube 30.
The cyclone 3 also functions as a heat exchange cyclone because it is eventually cooled by coming into contact with the cold water or the cold water that has been heat exchanged as described above. Refrigerants, especially high temperature refrigerants (
(approximately 1°C to -5°C) is the direction of arrow C, that is, the refrigerator →
It is circulated in the order of cooling supply pipe 9 → evaporation pipe 50 → cooling discharge pipe 10 → refrigerator.

4 is a heating and humidity control chamber, and this chamber 4 is arranged around the outer periphery of the cyclone 3 for heat exchange.

In the drawing, an annular air passage 15 is arranged between the chamber 44 and the cyclone 6 for sending the air discharged from the outlet pipe 11 of the heat exchange cyclone 6 downward.

Furthermore, the annular air passage 15 and the heating and humidity control chamber 4 are partitioned by a heat insulating cylindrical body 2, and the heat exchange between the cyclone 3 and the annular air passage 15 and the heating and humidity control chamber 4 is separated. conduction is blocked. A ventilation fan 54 is provided in the heating and humidity control chamber 4, so that heating and humidity control air can be sent to a separate section. The heating and humidity control chamber 4 and the heat exchange cyclone 3 may be provided with cleaning pipes for cleaning the inside. A heating pipe 18 is disposed within the heating and humidity control chamber 4, and the heating pipe 18 is connected to a heat source consisting of a heat radiation pipe of a refrigerator box via a heating supply pipe 19 and a heating discharge pipe 20.

Arrows indicate the direction of flow of air, arrow B indicates the direction of flow of cooling water, arrow C indicates the direction of flow of coolant, and arrows indicate the direction of flow of heating fluid.

As the heating source for the heating tube 18, an electric heater, gas heater, steam, etc. can be used separately as appropriate.

If the heat dissipation section of refrigerator B is used as in this embodiment.

Cooling and heating can be performed simultaneously with a single refrigerator, which is not only very economical, but also allows the vacuum cleaner itself to be made compact. In other words, one aspect of the present invention is.

The refrigeration system is utilized extremely effectively to provide an energy-saving, lightweight, compact, and high-performance vacuum cleaner.

The function of this vacuum cleaner will be explained. The air in the chamber is blown into the heat exchange cyclone 3 through the inlet pipe 8 and the inlet 32. The blown air is brought to a saturated relative humidity by spraying or jetting cold water and is cooled by direct contact with the evaporator tube 60 of the refrigerator box. , about 7° C., temperature about 1001) is sent out from the outlet pipe 11. The flow of the sent air is promoted by the action of the fan B, and the air flows through the annular air passage 15.
is sent into the air and swept downward. Of course, the temperature and humidity of the air in the heat exchange cyclone 6 are controlled by the evaporation tube 60, that is, the spiral tube of the cooling mechanism, and the temperature of the water to be sprayed. The air that has proceeded downward through the annular air passage 15 is sent into the heating and humidity control chamber 4 through a communication passage 21 provided at its lower part. The communication path 21 is formed by cutting out the lower part of the heat insulating cylindrical body 2. The air blown into the heating and humidity control cyclone 4 is heated by the spiral heating tube 18 (for example, about 20°C,
Humidity approximately 60 degrees). In this way, the overhumidified air is dehumidified, and the air whose temperature and humidity are controlled to a predetermined temperature and humidity is sent into the room through the air supply pipe 22. Air is circulated as described above.

In this way, like a general vacuum cleaner, indoor dust and bacteria are sucked in and removed along with the air, and the purified air is discharged into the room after being controlled in temperature and humidity. be.

〔Effect of the invention〕

The vacuum cleaner according to the present invention is fundamentally different from conventional vacuum cleaners, which suck indoor dust and dirt together with the air and only filter out large particles, and uses a completely new system called fine water droplet processing. By adopting this technology, it is possible to remove not only fine dust and dust, but also harmful fungi, making extremely clean and high-performance cleaning possible.

Therefore, the vacuum cleaner according to the present invention can of course be used freely at home, but also in laboratories, hospitals, and LSI factories where ultra-clean environments are required.

It is particularly suitable as a vacuum cleaner for electrical equipment factories, pharmaceutical manufacturing factories, vaccine manufacturing factories, and precision machinery factories.

Additionally, if a refrigerator is attached, air conditioning can also be performed. In other words, the sucked dirty air is removed from dust and sterilized, then brought to a saturated humidity level at a low temperature, and then raised to a predetermined temperature, which naturally adjusts the humidity. Humidity control is easy and reliable, and during cooling, water is sprayed against the evaporator tube so that the water does not freeze on the evaporator tube, and the air is directly directed to the evaporator tube in the absence of freezing. Since it is always in contact, cooling efficiency is extremely high.

Further, since the heating and humidity control chamber is arranged around the outer periphery of the heat exchange cyclone, the air conditioner itself can be made very compact, and the vacuum cleaner can be made smaller. Furthermore, in the vacuum cleaner according to the present invention, since the fan is disposed downstream of the heat exchange cyclone, that is, above the outlet pipe, the air flow is promoted extremely smoothly. Since it is located on the center line of the replacement cyclone, it has many advantages such as no vibration of the device caused by the fan and almost no noise.
