Description

  The present invention provides an air that is brought into a good state for the environment and discharged to the outside by applying a treatment such as filtration, heating or cooling to the external air, such as a vacuum cleaner, an air cleaner, an air conditioner, a refrigerator, etc. The present invention relates to a processing apparatus.

Generally, the vacuum cleaner simply removes the external air sucked from the floor suction tool in the dust collecting chamber and discharges the filtered air to the outside, and does not perform any further processing. Recently, it has been noted that negative ions are effective for physical health, and it is recommended that negative ions be diffused indoors by installing a negative ion generator in the room.
The applicant of the present application installs a negative ion generator at the exhaust port of the vacuum cleaner, thereby mixing negative ions into the exhaust discharged into the room at the same time as cleaning the room with the vacuum cleaner, A diffusion vacuum cleaner was proposed (Patent Document 1).

  This vacuum cleaner has the advantage that negative ions can be diffused indoors without installing a negative ion generator by cleaning the floor by operating a fan. However, since this vacuum cleaner generates negative ions by applying a high voltage between the electrodes in the negative ion generator and discharging it, ozone is generated at the same time as the negative ions. It was found to increase the concentration. Ozone is effective for the environment because it is expected to be sterilized at low concentrations, but if it exceeds a predetermined concentration, ozone has a problem of harming the body

  Recently, a configuration shown in FIG. 5 has been proposed as an apparatus that generates negative ions and uses them for film forming technology (Patent Document 2). The apparatus communicates the internal space of the container to the external space through a critical orifice, and arranges a first electrode in the vicinity of the critical orifice, a first electrode facing the first electrode, a second electrode in the internal section, and a predetermined internal space. A gas containing substance molecules is supplied, and a predetermined voltage is applied between the electrodes by a high voltage power source. The gas molecules are ionized and ejected from the orifice to expand into negative ion cluster ions. The negative ions are mixed with the nanoparticles in an electric field, attached to the nanoparticles and charged, and the charged nanoparticles are deposited on the surface of the deposited member to form a film.

  Although this apparatus can generate a large amount of negative ions, since it is an apparatus exclusively for film formation, there is no disclosure as to whether it can be implemented for air treatment or improvement of the living environment. .

  In the present invention, a large amount of negative ions is formed by the ionizer, but the reason why the amount of generated ozone can be kept low is not necessarily clear, but the gas supply device pressurizes the gas of the molecule to be ionized. By supplying the discharge chamber in a state, the gas molecule density is increased in the discharge chamber. Therefore, the electric resistance value between the first and second electrodes is higher than that in the atmospheric pressure state, and arc discharge is unlikely to occur. If the potential difference between the electrodes is kept constant and the gas pressure supplied to the discharge chamber by the gas supply device is changed, the amount of ozone generated decreases as the gas pressure increases, so the above estimation is made.

  The air conditioner according to the fourteenth aspect is convenient because the dew condensation water generated during operation is used as replenishment water for bubbling to be negatively ionized, so that the dew condensation water treatment and the water replenishment of the water storage container can be performed simultaneously.

  Since the air conditioner of Claims 16 and 17 generates a large amount of negative ions of water molecules by the ionization device, the food is stored with the negative ions stably filled and stored without lowering the humidity in the refrigerator. Can be kept fresh. If desired, substances having effects such as sterilization, deodorization, and allergen deactivation can be negatively ionized and released to keep the inside hygienic. Moreover, since the amount of ozone generated is low in the negative ionization apparatus of the present invention, there is little ozone flowing out from the inside when the door is opened, and the health and safety of the user can be protected.

  As shown in FIG. 5, the negative ionization apparatus forms a sealed discharge chamber space by a housing made of an insulating material, and the discharge chamber is an orifice having an inner diameter of 0.1 to 0.4 mm opened on one wall. It communicates with the external space through. A first electrode 13 is arranged close to the orifice on the inner surface of the discharge chamber wall where the orifice is opened, and a needle-like second electrode 14 is separated from the orifice by a predetermined distance from the first electrode in the discharge chamber space. It is arranged on the same line. The first electrode is grounded, and a high voltage power source is connected to the second electrode, and a DC high voltage (for example, −6 KV) is applied between the electrodes. The orifice is a critical orifice, and a diffuser that is formed of a heat insulating member and whose inner surface is enlarged is disposed outside the orifice.

A gas supply device is connected to the discharge chamber, and a gas of molecules to be negatively ionized is supplied in a pressurized state by an air pump. The gas supply device shown in FIG. 5 shows a configuration for supplying a water molecule gas to the discharge chamber by bubbling water. Water is stored in a sealed water reservoir, and an air supply pipe connected to an air pump penetrates the water reservoir tightly, extends the tip to the bottom of the water reservoir, and blows pressurized air into the water. . Air forms bubbles and bounces on the surface of the water, filling the top of the water surface in the water reservoir with water vapor. The upper part of the water storage container communicates with the discharge chamber in an airtight manner via a gas supply pipe, supplies pressurized air containing water vapor to the discharge chamber, and discharges the discharge chamber space at a predetermined pressure (0.5 to ² kg / cm ² ). Fulfill. If the pressure falls below 0.5 kg / cm ² , arc discharge is likely to occur between the electrodes, and the amount of ozone generated increases. If the pressure exceeds 2 kg / cm ² , the pressure is too high and each part of the apparatus must be strengthened to withstand the pressure, which increases the weight and price and is not preferable for household use.

  In the discharge chamber, a high voltage is applied between the first and second electrodes, but in the pressurized chamber, the density of gas molecules is high and no arc discharge occurs, and the needle tip of the second electrode, the first electrode, Corona discharge is generated between the gas and the gas molecules filling the discharge chamber. From the orifice, a jet of negatively ionized molecular ions is ejected, and when adiabatic expansion is performed by the diffuser, non-ionized molecules aggregate around the ionized molecules to form nano-sized droplets with a negative charge. To do. Then, the droplets are discharged into the air, and dust floating in the air is aggregated and lowered to the floor to clean the air.

  In the water storage container, if necessary, effective substances having sterilization, deodorization, and aromagen deactivation effects may be dissolved, and these effective substances may be mixed with water molecules and supplied to the discharge chamber. Alternatively, separately from the gas supply device shown in FIG. 5, a container (not shown) containing an effective substance is connected to the discharge chamber, and the containing container is heated by heating means to vaporize the effective substance and connected to the containing container. The gas molecule of the active substance may be pressurized and fed into the discharge chamber by the air pump.

  FIG.1 and FIG.2 shows the example which implemented this invention to the dust bag type vacuum cleaner. The main body of the vacuum cleaner has a dust bag attached to the floor suction tool hose connection port in a detachable manner. A suction fan and a fan motor are arranged downstream of the dust bag through a protective cover, and a part of the blown air from the fan returns to the floor suction port through the passage between the circulation passage and the double pipe of the hose. . The water supply container of the gas supply device is placed on the fan motor, and the air supply pipe of the air pump is inserted into the water storage container. A gas supply pipe extending from the water storage container is connected to a discharge chamber of a negative ionization apparatus disposed at the lower part of the apparatus. Since the fan motor is a heat generating structure, the motor heat generated during operation heats the water storage container and vaporizes substances to be ionized such as water and aroma in the container. Most of the air blown out from the suction fan is mixed with the negative ion jet from the negative ionizer through the protective cover, and the exhaust flow is divided into both sides of the main body of the equipment. It is discharged into the external space from the center of the annular wheel that is rotatably supported on the periphery of the wheel. A filter is provided in the center of the exhaust port or the annular wheel, and the exhaust gas is filtered and discharged at a low position near the floor, adsorbs dust in the living space and quickly descends to the floor. When the effective substance is ionized, the carpet is sterilized and deodorized effectively. Since the space at the center of the wheel is used as an exhaust port, the exhaust area is widened, the momentum of the exhaust flow velocity is reduced, and no dust is blown up on the floor.

  3 and 4 show an example in which the present invention is implemented in a cyclonic vacuum cleaner. Between the suction fan and the connection port of the floor suction tool hose, a cyclone dust collecting unit is detachably disposed through a filter. The exhaust flow of the suction fan is discharged obliquely upward from an exhaust port provided in the rear wall of the apparatus main body. The negative ionizer and the air pump of the gas supply device and the water storage container are arranged on the side of the suction fan, and the air supply pipe extending downward from the air pump blows air into the water of the water storage container, and the upper part of the water storage container. And a discharge chamber of the negative ionizer are connected by a gas supply tube, and pressurized air containing water molecules is supplied to the discharge chamber. Minor particles of negative ions are discharged obliquely upward from the orifice of the discharge chamber, like the exhaust flow, are attracted to the exhaust flow and mixed, adhere dust etc. floating in the living space, and descend to the floor, Purify indoor air.

  6 to 8 show examples in which the present invention is implemented in the air purifier 5. Air intake ports 51 are provided on both front sides of the apparatus main body 50, and air outlets 55 are provided on the upper surface. The fan 53 provided in the apparatus main body is operated by the motor 54 so that indoor air can be introduced from the air intake openings 51. The filter 52 provided inside the apparatus main body removes dust, disinfects, and deodorizes, blows out from the outlet 55, and returns to the room. The negative ionizer 1 is disposed near the air pump 20 and the outlet 55 in the lower part of the apparatus main body, and the water storage container 21 of the gas supply device is disposed on the side. Compressed air is blown into the water stored in the water storage container 21 by the air pump 20. The water storage container 21 and the negative ionizer 1 are connected by a gas supply pipe 24, and pressurized air containing water molecules is sent to the discharge chamber of the negative ionizer 1. The air taken into the air purifier 5 is filtered by the air filter 52 as in the conventional air purifier, and further, negative ions released from the negative ionization device 1 disposed in the vicinity of the outlet 55. Alternatively, the negatively ionized effective substance having the effect of sterilization, deodorization, or allergen deactivation is mixed to perform treatment such as sterilization, deodorization, allergen deactivation, etc., and the indoor air can be purified.

  9 and 10 show examples in which the present invention is implemented in the air conditioner 6. The apparatus main body 60 includes a filter 62 at the air intake 61, and a fan 64 and a heat exchanger 63 are disposed inside the apparatus main body. The air flow flowing from the intake 61 is filtered by the filter 62, and the heat exchanger 63 Then, after being heated or cooled to the set temperature, it is guided by the blower flap 65 and discharged into the room from the outlet 67. The negative ionization device 1 is disposed in the vicinity of the outlet 67, the gas supply device 2 including the air pump 20 and the water storage container 21 is installed on the back side of the fan cover, and the pressurized gas molecules are supplied to the gas supply pipe 24. Through the discharge chamber 11 of the negative ionization apparatus 1. Since the negative ionization apparatus 1 spreads an effective substance having an effect of sterilization, deodorization, or allergen deactivation that suppresses the generation amount of ozone to a low level or a level of negative ions, not only temperature adjustment, Dust removal, sterilization, and allergen deactivation are added, and indoor air can be improved to a more favorable state for recovery of physical health and physiological function.

  In an air conditioner, since condensed water is generated in a heat exchanger, it needs to be collected in a drain pan 66 and processed. In the present invention, the condensed water collected in the drain pan 66 can be supplied to the water storage container 21 of the air supply device and used as a raw material for generating water molecular ions. The configuration for replenishing the water storage container 21 with condensed water from the drain pan 66 is arbitrary. For example, a water supply pipe is connected to the water storage container 21 via a solenoid valve (not shown) for water replenishment. However, when water is supplied, the air pump 20 may be stopped to return the pressure of the water storage container to atmospheric pressure, and the electromagnetic valve may be opened to allow condensed water to flow into the water storage container.

  FIG. 11 thru | or 13 shows the example which implemented this invention to the electric refrigerator 7. FIG.

  The electric refrigerator includes a door 71 on the front surface of the apparatus main body 70, forms a sealed space for storing food and the like, and includes a cooler 72 and a fan 73 in a circulation duct formed between the back panel and the heat insulating wall. The air flowing in from the inlet 74 at the lower end of the duct is cooled, discharged from the outlet 75 and circulated in the cabinet. In the present invention, the negative ionization device 1 is disposed in the vicinity of the outlet 75, the gas supply device 2 including the air pump 20 and the water storage container 21 is disposed in the circulation duct, and the pressure air containing water molecules is supplied as a gas. The negative ion molecules are mixed in the cold air supplied to the negative ionization apparatus 1 through the tube 24 and blown out into the warehouse, and circulated in the warehouse. Below the cooler 72, a defrost heater 76 and a water collector 79 for collecting condensed water are disposed. The water collector 79 collects the condensed water and flows it into the condensed water tank 77 to store the condensed water. It is used for replenishing tank water. Water in the dew condensation water tank 77 is supplied to the water storage container 21 through the electromagnetic valve 78 in a timely manner.

  14 to 18 show the cyclonic vacuum cleaner 8. The dust collection unit 41 is provided with a charge filter 80 downstream of the swirl chamber. The floor suction part of the vacuum cleaner is provided with an ion generator 82 of an arbitrary type such as a discharge type, the deployment of an ion generating substance, etc., and ions are mixed into the air flow sucked from the floor, and the floor suction part 81 through the vacuum cleaner 8 Until passing through the duct 83, the fine dust contained in the intake air is charged.

  In the cyclone type vacuum cleaner, the dust collection unit has a known structure, and large dust in the air sucked by the fan 85 is removed with high performance by centrifugal force. However, fine dust floating in the air is difficult to remove by centrifugal force because the centrifugal force does not act so much. Therefore, the filter 84 provided at the outlet of the dust collecting unit is made of a fine mesh that can handle fine dust, thereby increasing the air resistance. In the present plan, ions are mixed in the inflowing air to charge fine dust, so that it is attracted by the electrostatic action by the charge filter 80 and can be easily removed. Therefore, it works effectively against fine dust, which was a weak point of cyclone vacuum cleaners, and it is not necessary to make the mesh of the outlet filter fine, so the air resistance is small and the power consumption of the fan 85 is saved. There are many advantages such as being able to.

  The dust bag shown in FIG. 19 can be used in FIG. 1 or the conventional dust bag type vacuum cleaner, and has a sterilization, deodorization, allergen deactivation effect, etc. on a part of the bag formed of a filter medium. A certain active substance is deployed. Effective substances contained in the exhaust flow blown out from the vacuum cleaner act on the air, purify the indoor air, and are effective in improving the living space.
