Since it takes time to fall, there was a problem that an air cleaning effect could not be sufficiently obtained.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object thereof is to provide a vacuum cleaner that can prevent the discharge electrode from freezing even at low temperatures and can generate negative ion mist quickly and reliably. To do.

  The first invention includes an electric blower that generates suction air, a discharge electrode, an electrode cooling unit that cools the discharge electrode, and a nanoe ion generation unit that generates nanoe ions by applying a high voltage to the discharge electrode. A blower fan for discharging the nanoe ions generated by sucking outside air, a temperature detection unit for detecting a temperature in the vicinity of the nanoeion generation unit, and a nanoeion generation unit storage chamber in which the nanoeion generation unit is stored When the temperature detected by the temperature detection means is lower than a predetermined value, a communication passage that communicates with the electric blower storage chamber in which the electric blower is accommodated, and a passage opening / closing means that opens and closes the communication passage. A communication passage is opened to allow a part of the exhaust air from the electric blower to flow into the nanoeion generating means storage chamber. Adds mass of condensate to expedite the fall to the floor surface, and quickly and reliably discharges nanoe ions that improve the collection rate of dust that can be sucked out from the suction tool being cleaned. It is possible to provide an electric vacuum cleaner that is effective in deodorizing and sterilizing dust to which ions are attached, and that has a good air cleaning effect.

  In particular, the second invention controls the opening / closing amount of the passage opening / closing means in accordance with the temperature detected by the temperature detecting means of the first invention, thereby varying the amount of exhaust air flowing into the nanoeion generating means storage chamber. For example, when the detected temperature is close to a predetermined temperature, the amount of opening and closing is reduced to suppress the disappearance of mist due to the heat of the exhaust air from the electric blower. Conversely, the detected temperature is the predetermined temperature. On the other hand, if the opening / closing amount is increased so that the temperature in the vicinity of the discharge electrode quickly rises to a predetermined value when the temperature is considerably low, it is possible to provide a vacuum cleaner that reliably generates negative ion mist at a low temperature.

  The third invention particularly includes an electric blower chamber temperature detecting means for detecting the temperature in the electric blower storage chamber of the first invention, and the opening / closing amount of the passage opening / closing means according to the detected temperature of the electric blower storage chamber. The amount of exhaust air flowing into the nanoeion generating means storage chamber is made variable.For example, when the detected temperature is close to a predetermined temperature, the opening / closing amount is reduced, so that the heat of the exhaust air from the electric blower On the contrary, when the detected temperature is considerably lower than the predetermined temperature, the mist disappears, and if the switching amount is increased so that the temperature in the vicinity of the discharge electrode quickly rises to the predetermined value, the lower the temperature, the faster. An electric vacuum cleaner that reliably generates negative ion mist can be provided.

In particular, the fourth aspect of the invention provides the vacuum cleaner according to the first aspect of the present invention with operation means for selecting an operation mode, controls the opening / closing amount of the passage opening / closing means according to the selected operation mode, and stores the nanoeion generating means. For example, if the operation mode is `` strong '', the suction power is high and the electric fan generates a large amount of heat, the opening / closing amount is reduced to reduce the exhaust air flow of the electric fan. If the mist disappears due to heat and the operation mode is “weak”, the suction force is small and the heat generation amount of the electric blower is small, the temperature near the discharge electrode quickly rises to a predetermined value. Thus, if the amount of opening and closing is increased, a vacuum cleaner that can generate negative ion mist more quickly and reliably at low temperatures can be provided.

  In the fifth invention, in particular, when the temperature detected by the temperature detecting means of any one of the first to fourth inventions is lower than a predetermined value, the blower fan is stopped, and the inflow of outside air to the discharge electrode is stopped. Thus, the temperature in the vicinity of the discharge electrode can be raised to a predetermined value more quickly. Thereby, the vacuum cleaner which produces | generates a negative ion mist earlier at low temperature can be provided.

  In the sixth aspect of the invention, in particular, the passage opening / closing means of the first aspect of the invention is made of bimetal and also serves as a temperature detection means, and the construction can be facilitated and an inexpensive electric vacuum cleaner can be provided.

  In the seventh aspect of the invention, in particular, the communication passage opening on the nanoe ion generation means storage chamber side of the communication passage of any one of the first to sixth aspects is disposed in the vicinity of the discharge electrode. It is possible to provide a vacuum cleaner that can increase to a predetermined value and generate negative ion mist more quickly at low temperatures.

  In the eighth invention, in particular, the inflow exhaust air from the electric blower is not directly blown to the discharge electrode through the communication passage opening on the nanoeion generating means storage chamber side of the communication passage of any one of the first to seventh inventions. With this arrangement, it is possible to provide a vacuum cleaner that suppresses the disappearance of mist when exhaust air blows directly against the discharge electrode, and generates negative ion mist more reliably.

  In the ninth aspect of the invention, in particular, a filter is provided in the communication path of any one of the first to eighth aspects of the invention, and dust can be prevented from adhering to the discharge electrode. Can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

Control is performed at a temperature at which moisture around the electrode 25 is condensed.

  With this configuration, the needle-like electrode 25 to which a high voltage (for example, approximately 6000 V) of the nanoeion generating means 33 is applied is cooled by the Peltier effect of the built-in Peltier element 23 to condense moisture in the air, and corona discharge As a result, fine particles of negative ions (for example, negative ion mist having a diameter of about 5 to 20 nm) are generated.

  The blower fan 35 is a discharge unit that discharges nanoe ions into the room and generates an air flow for diffusion. The blower fan 35 takes in indoor air from the intake port 36, blows it to the nanoe ion generation unit 33, and from the nanoe ion release port 37. Release nanoe ions into the room. 29 is a main exhaust port for discharging the exhaust of the electric blower 2, and generates an air flow for diffusing the released nanoe ions into the room.

  Here, there is a communication passage 50 (which may be a communication hole) for communicating the electric blower storage chamber 20 of the electric blower 2 and the nano ion generation means storage chamber 21 of the nano ion generation means 33, and the exhaust of the electric blower 2 A part flows into the nanoeion generating means storage chamber 21 and is discharged from the nanoeion release port 37 via the nanoeion generating means 33.

Further, a temperature detection means 38 is disposed in the vicinity of the needle electrode 25 of the nano-ion generation means 33 in the nano-ion generation means storage chamber 21, and the communication path 50 has a passage area of the communication path 50. A variable passage opening / closing means 53 is provided, and the opening / closing amount of the communication path 50 is controlled by controlling the passage opening / closing means 53 through the passage opening / closing control means 39 based on the temperature detected by the temperature detection means 38. It has become.

  The communication passage port 54 on the nanoeion generating means storage chamber 21 side into which the exhaust air from the electric blower 2 with heat discharged from the communication path 50 flows in is a needle-like shape of the nanoeion generation means 33 as shown in FIG. It is arranged in the vicinity of the electrode 25. Further, an exhaust air blocking wall 55 is provided around the needle-like electrode 25 so that exhaust air from the electric blower 2 is directly blown to suppress the disappearance of the negative ion mist.

  Reference numeral 51 denotes a filter A for preventing dust from entering the nanoeion generation unit storage chamber 21 of the nanoeion generation unit 33 due to the intake of indoor air by the blower fan 35. Can be removed to remove dust. A filter B 52 prevents dust from entering from the communication path 50.

  Reference numeral 40 denotes a nanoe drive unit that operates the nanoe control unit 21. When the control unit 30 is driven, power is supplied to the nanoe control unit 21. When power is supplied to the nanoe control means 22, a high voltage is applied between the needle electrode 25 and the ground electrode 26 by the high voltage generator 27, and a voltage is further applied to the Peltier element 23 that is an electrode cooling means. The blower fan 35 is controlled by the control means 30. The temperature detected by the temperature detecting means 38 is fed back to the passage opening / closing control means 39 via the control means 30, and the passage opening / closing control means 39 controls the passage opening / closing means 53 according to the detected temperature. The passage area of the communication passage 50 is varied. 41 is a commercial power source for supplying power to the vacuum cleaner.

  About the vacuum cleaner in this Embodiment comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  When the user operates the operation unit 6 and selects, for example, “medium” which is one of the operation modes, the control unit 30 uses the electric blower drive unit 31 and the motor drive based on the information from the operation unit 6. A predetermined signal is sent to the means 32 to drive the electric blower 2 and the electric motor 13. Then, the control unit 30 operates the blower fan 35, and the blower fan 35 takes in the indoor air from which dust has been removed by the removable filter A 51 from the intake port 36, and passes through the nanoe ion generating unit 33 to nanoeion. Released from the ion emission port 37.

Further, the control means 30 sends a signal to the nanoe drive means 40, and electric power is applied to the nanoe control means 22. The nanoe control means 22 to which power is applied outputs a high voltage from the high voltage generator 27 and is applied between the needle electrode 25 and the ground electrode 26 of the nanoe ion generator 33. Further, the DC power supply means 28 outputs a voltage to the Peltier element 23 to cool the needle electrode 25. When the needle-like electrode 25 is cooled, the surrounding moisture is condensed, and water is generated in the needle-like electrode 25. When a high voltage is applied to the water, fine particles of negative ions (for example, encased in fine particle water) Nanometer-sized negative ion mist having a diameter of about 5 to 20 nm) is generated. Nanometer-sized negative ion mist can exist in the air for a longer time (with a life of about 6 times that of negative ions) than when negative ions are present alone, and is very small with nanometer size. It can float in the air for a long time and has high diffusivity, so it floats evenly in the room.

  At this time, when the temperature in the vicinity of the needle electrode 25 detected by the temperature detection means 38 is a predetermined temperature (for example, 5 ° C.) or less, the cooled needle electrode 25 becomes 0 ° C. or less and the needle electrode 25 is cooled. Since the moisture condensed in the water freezes and negative ion mist can no longer be generated, the control means 30 controls the passage opening / closing means 53 through the passage opening / closing control means 39 to open the communication passage 50 and to open the electric blower 2. A part of the exhaust air generated in step 1 is introduced to raise the temperature in the vicinity of the needle-like electrode 25, and freezing of moisture in the needle-like electrode 25 is suppressed, so that nanoe ions are reliably generated even in a low-temperature environment.

  When the temperature in the vicinity of the needle-like electrode 25 detected by the temperature detecting means 38 becomes a predetermined temperature (for example, 5 ° C.) or more, the control means 30 controls the passage opening / closing means 53 through the passage opening / closing control means 39, and The passage 50 is closed.

  Due to the configuration of the vacuum cleaner in the present embodiment that releases nanoe ions into the room, the temperature in the vicinity of the needle electrode 25 detected by the temperature detection means 38 at the start of use of the vacuum cleaner is substantially equal to the temperature of the outside air. Needless to say. Accordingly, the same effect can be obtained even if the temperature detecting means 38 is constituted by means for detecting the temperature of the outside air.

  When the temperature in the vicinity of the needle electrode 25 detected by the temperature detection means 38 is a temperature (for example, −5 ° C.) considerably lower than a predetermined temperature (for example, 5 ° C.), the cooled needle electrode 25 is Therefore, the control means 30 controls the passage opening / closing means 53 through the passage opening / closing control means 39 so that a large amount of exhaust air generated in the electric blower 2 flows in and the temperature in the vicinity of the needle electrode 25 is quickly raised. In addition, the passage area of the communication passage 50 is increased.

  Conversely, when the temperature in the vicinity of the needle electrode 25 detected by the temperature detecting means 38 is a temperature (for example, 4 ° C.) close to a predetermined temperature (for example, 5 ° C.), the mist is generated by the heat of the electric blower 2. In order to suppress the disappearance, the control means 30 controls the passage opening / closing means 53 through the passage opening / closing control means 39 so as to reduce the amount of exhaust air generated by the electric blower 2, thereby reducing the passage area of the communication passage 50. Try to make it smaller.

  Further, when the temperature in the vicinity of the needle electrode 25 detected by the temperature detection means 38 is lower than a predetermined temperature (for example, 5 ° C.), the control means 30 stops the blower fan 35 so that the use of the vacuum cleaner is started. By suppressing the inflow of outside air having a temperature substantially equal to the temperature detected by the temperature detection means 38 in FIG. 3 and rapidly raising the temperature in the vicinity of the needle electrode 25, nanoe ions are generated quickly. In particular, since the general usage time of a vacuum cleaner is several minutes, it is useful to generate nanoe ions earlier.

  The generated nanoeion is discharged from the nanoeion discharge port 37 by the blower fan 35 or a part of the exhaust air flow of the electric blower 2.

  Nanoe ions released from the nanoeion discharge port 37 are diffused into the room by the air blown by the blower fan 35 and the exhaust air from the electric blower 2, attached to and charged with fine dust floating in the room, and dropped onto the floor surface. it can. Dust which nanoe ions are attached and charged and dropped is sucked from the suction tool 10, passes through the extension tube 9 and the hose 8, and then collected in the electret-processed dust collection bag 3.

In addition, nanometer-sized nanoe ions are known to be highly reactive and have the ability to act on odorous components and decompose them into odorless components, resulting in deodorizing effects such as indoor curtains and floating dust. High effects are also obtained against inactivation of allergens and viruses floating or adhering in the room and sterilization of molds, bacteria, and the like.

  Here, the test result according to the test method of standard JEM1467 of an air cleaner is shown using the conventional vacuum cleaner and the electric vacuum cleaner in the present embodiment.

In the test, in a measurement chamber of 20 to 30 m ³ , five cigarettes are smoked with a cigarette smoker, and a concentration distribution is made constant while operating a stirring fan (not shown) similar to the cigarette smoker. Then, while operating the vacuum cleaner, the decay rate of tobacco smoke having a particle diameter of 0.3 μm is measured every hour. FIG. 5 is a graph showing the results of the above test. In the comparison after 5 minutes of operation time, the removal rate of the vacuum cleaner in this embodiment was about 20% better than that of the conventional vacuum cleaner. It was.

  It can be seen from the graph that tobacco smoke settles on the floor more quickly and collects dust than a conventional vacuum cleaner. Cigarette smoke used this time is one of the floating dusts, but there are various particle sizes as floating dusts, and up to about 1 μm. In addition, pollen and the like in sedimentary dust have a long time of floating with a particle diameter of several tens of μm. Of the floating particles, the larger the particle diameter, the more negative ion mist can be attached and charged, so that the sedimentation to the floor surface can be expected earlier.

  As described above, according to the present embodiment, in the vacuum cleaner provided with the electric blower 2, the temperature detecting means 38 for detecting the temperature in the vicinity of the needle electrode 25, the nanoeion generating means accommodating chamber 21, and the electric blower. A communication passage 50 that communicates with the storage chamber 20 is provided, and the passage opening / closing means 53 is controlled through the passage opening / closing control means 39 in accordance with the detected temperature detected by the temperature detection means 38 to open and close the low temperature. Even under the environment, the mass of fine particle water is added to make the fall to the floor quicker, and the nanoe ion that improves the collection rate of dust that can be sucked from the suction tool 10 during cleaning is quickly and reliably stabilized. In addition, it is possible to provide an electric vacuum cleaner that is effective in deodorizing and sterilizing dust having nanoe ions attached thereto and having an excellent air cleaning effect.

  When the negative ion mist of nanometer size is released by the exhaust of the electric blower 2 like ions, the mist disappears due to the heat of the electric blower 2 and the effect cannot be obtained. Since the outside air is taken in and the negative ion mist is discharged with air without heat, the effect of the negative ion mist can be obtained stably.

  Furthermore, in order to generate negative ions, the needle-like electrode 25 must be cooled by the heat radiation fins 24 to condense the moisture. Therefore, if the temperature in the vicinity of the needle-like electrode 25 is about 5 ° C. or less, the needle-like electrode Moisture that condenses on 25 freezes and no negative ion mist can be generated. Since it is configured to discharge negative ion mist by sucking outside air, the outside air is normally 5 ° C. or lower in winter, and the vicinity of the needle electrode 25 due to the heat generated by the electric blower 2 in the vacuum cleaner body 1. The negative ion mist cannot be generated until the temperature of the gas rises. The normal use time of a vacuum cleaner is several minutes, and it becomes useful to generate a negative ion mist in several tens of seconds after using the vacuum cleaner. On the other hand, in the present embodiment, when the temperature in the vicinity of the needle electrode 25 is low, the exhaust air of the electric blower 2 is caused to flow into the vicinity of the needle electrode 25 so that the needle electrode 25 is at a low temperature. Can be prevented, and negative ion mist can be generated quickly and reliably.

A part is flowed in, the temperature in the vicinity of the needle electrode 25 is increased, freezing of the needle electrode 25 is suppressed, and nanoe ions are reliably generated even in a low temperature environment.

  At this time, if the temperature detected by the electric blower chamber temperature detecting means 60 is higher than a predetermined value, the temperature in the vicinity of the needle electrode 25 can be increased without having to flow in a large amount of exhaust air generated by the electric blower 2. The control means 30 controls the passage opening / closing means 53 through the passage opening / closing control means 39 so as to reduce the passage area of the communication passage 50 so as to suppress the disappearance of mist due to the heat of the electric blower 2. .

  On the contrary, when the detected temperature detected by the electric blower room temperature detecting means 60 is lower than a predetermined value, the control means is configured to quickly increase the temperature in the vicinity of the needle electrode 25 by causing a large amount of exhaust air generated in the electric blower 2 to flow in. 30 controls the passage opening / closing means 53 through the passage opening / closing control means 39 so as to increase the passage area of the communication passage 50.

  When the temperature in the vicinity of the needle electrode 25 detected by the temperature detecting means 38 becomes a predetermined temperature (for example, 5 ° C.) or more, the control means 30 controls the passage opening / closing means 53 through the passage opening / closing control means 39 to 50 is closed.

  As described above, according to the present embodiment, by providing the electric blower chamber temperature detection means 60, the amount of heat flowing into the nanoeion generating means storage chamber 21 can be controlled more optimally.

The vacuum cleaner in the 3rd Embodiment of this invention is demonstrated using FIG.

  FIG. 8 is a control block diagram of the electric vacuum cleaner in the present embodiment. In addition, the same code | symbol is attached | subjected to the same part as the vacuum cleaner in the said embodiment, and the description is abbreviate | omitted.

In the vacuum cleaner in this embodiment, switch operation information of the operation means 6 operated by the user is fed back to the passage opening / closing control means 39 via the control means 30, and the passage opening / closing control means 39 is selected in the selected operation mode. The passage opening / closing means 53 is controlled according to (for example, suction force such as strong / medium / weak / cut), and the passage area of the communication passage 50 is made variable. It is the same as the vacuum cleaner in the form.

  About the vacuum cleaner in this Embodiment comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  When the temperature in the vicinity of the needle electrode 25 detected by the temperature detection means 38 is a predetermined temperature (for example, 5 ° C.) or less, the cooled needle electrode 25 becomes 0 ° C. or less and condensation occurs on the needle electrode 25. Since the water freezes and negative ion mist cannot be generated, the control means 30 controls the passage opening / closing means 53 via the passage opening / closing control means 39 to open the communication passage 50 and generate it in the electric blower 2. A part of the exhausted air is introduced to raise the temperature in the vicinity of the needle-like electrode 25 to suppress the freezing of moisture at the needle-like electrode 25 and to reliably generate nanoe ions even in a low temperature environment.
