Description

  The present invention relates to a deodorizing apparatus disposed in a deodorizing space such as a toilet room, for example.

  Generally, a deodorant such as commercially available activated carbon or a fragrance is placed in a toilet room. In other words, the deodorant is used to deodorize the toilet room, and the fragrance is diffused into the toilet room with the fragrance so that the user can have a good feeling of use of the toilet room.

  However, the deodorant adsorbs the odor component in the air of the toilet room and deodorizes it, and cannot deodorize the odor component adhering to the wall surface of the toilet room or the toilet. In addition, the deodorant range of the deodorant and the fragrance diffusion range of the fragrance are not immediately effective because they depend on the air flow in the toilet room. Furthermore, since such deodorizers and fragrances always have a deodorizing effect and aroma effect after they are placed in the toilet room, the increased odor component after using the toilet room (after stool) The effect of deodorizing such as powerful deodorizing is impossible, and it is wasteful and uneconomical because it keeps acting even when the toilet room is not used. There is a problem.

  By the way, according to recent research, nano-size mist generated by applying voltage to water with an electrostatic atomizer contains active species, and when this mist adheres to odor components, the odor components are inactivated. It is clear that it can be deodorized. Thus, by applying this principle, for example, Patent Document 1 discloses that an air atomizer is provided with an electrostatic atomizer. The air purifier of Patent Document 1 is provided with an electrostatic atomizer attached to the air path from the intake port to the exhaust port to deodorize odor components contained in the air flowing in the air path of the air purifier. However, if the mist produced | generated by electrostatic atomization is discharge | released to a toilet room by a ventilation means, the deodorizing apparatus which deodorizes the whole toilet room can be obtained.

By placing such a deodorization device in the toilet room and performing electrostatic atomization at an appropriate timing, it is possible to perform deodorization of the entire toilet room with immediate effect and economy, In order to dissipate the fragrance in the toilet room, it is necessary to place a separate fragrance, and there is a problem that the toilet room is cluttered with arrangements such as deodorizers and fragrances. It was done without economy.

Since the same air blowing means 5 can be used, the structure of the apparatus can be simplified and the deodorizing apparatus 1 can be miniaturized, and the deodorizing apparatus 1 can be placed in the deodorizing space and can be arranged well.

In addition, the water to be electrostatically atomized can be automatically covered with condensed water, and the convenience of the deodorizing device 1 is increased by eliminating the need for the user to manually supply water to the deodorizing device 1 and the dew condensation.

  The present invention allows the deodorizing and fragrance effects to act on the entire deodorizing space such as a toilet room in which the deodorizing device is arranged with immediate effect and economy, and simplifies the device configuration of the deodorizing device and reduces the size. Therefore, there is an advantage that the deodorizing device can be placed in the deodorizing space and can be arranged well.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  1 to 6 show examples of embodiments of the present invention. As shown in FIGS. 1 to 3, the deodorizing apparatus 1 includes an electrostatic atomizing means 3 for generating nanometer-size mist in a case 2 serving as an apparatus outer shell, and an fragrance evaporating means 4 for evaporating the fragrance. The toilet room 15 in which the generated mist and the evaporated fragrance can be diffused to the outside of the case 2 and the blower means 5 are provided, for example, as shown in FIG. The deodorizing space such as the deodorizing effect by the generated mist and the fragrance effect by the transcribed aroma can be imparted respectively.

  Specifically, in the deodorizing apparatus 1, a human body detection sensor 13 is disposed in front of the case 2 as shown in FIG. 3, and an intake port 16 and an exhaust port 17 are opened. As shown in FIG. A ventilation passage 18 extending from the intake port 16 to the exhaust port 17 is provided inside. An air purifying filter 20 and a blower fan 19 constituting the blower unit 5 are disposed in a portion of the blower passage 18 near the intake port 16, and the fragrance transpiration unit 4 is disposed in a portion of the blower passage 18 near the exhaust port 17. And the electrostatic atomization means 3 is arrange | positioned. Although not shown, a control unit connected to the power supply unit for operating each means and the human body detection sensor 13 is disposed inside the case 2 other than the air passage 18. Here, the air purifying filter 20 includes a dust removing filter 21 made of a fine mesh deposited over the intake port 16 and an odor removing filter 22 made of activated carbon or an oxidation catalyst. The dust removal filter 21 can remove dust and fine particles floating in the air so as not to enter the air passage 18, and the odor removal filter 22 absorbs and decomposes the odor component floating in the air. It can be removed. That is, the air purifying filter 20 cleans the air taken into the blower passage 18 by the blower fan 19 and dissolves unpleasant odors in the condensed water for electrostatic atomization of the electrostatic atomizer 3 to be described later. It is designed not to let it happen.

  As shown in FIGS. 1 and 2, the electrostatic atomizing means 3 includes an atomizing electrode 6 to which water is supplied to the tip portion, and a counter electrode 7 disposed to face the tip portion of the atomizing electrode 6. The high voltage applying unit 8 applies a high voltage between the atomizing electrode 6 and the counter electrode 7, and causes Rayleigh splitting in the water existing at the tip of the atomizing electrode 6. Nanometer-size mist is generated by electrostatic atomization. The generated mist has a nanometer size particle size and originally has good diffusibility. However, the generated mist is further diffused by being diffused from the exhaust port 17 to the deodorant space by being put on the wind generated by the blower fan 19. Becomes good and immediately spreads to every corner of the deodorant space. Here, water is required for electrostatic atomization, and in this example, this water is used as dew condensation water generated in the cooling unit 11 of the Peltier element 10 housed in the case 2. Thus, since the water to be electrostatically atomized is automatically provided in the form of condensed water from the moisture contained in the air, the user is not required to manually supply water to the deodorizing apparatus 1. Therefore, the convenience of the deodorizing apparatus 1 is enhanced. When the Peltier element 10 is energized, heat transfer occurs between the elements, a cooling part 11 that absorbs heat appears at one end, and a heat dissipation part 12 that generates heat appears at the other end. In this example, the cooling unit 11 of the Peltier element 10 is formed with a dish-shaped dew condensation water receiving portion 23 that can store dew condensation water, and is made of ceramic so as to protrude from the bottom of the dew condensation water receiving portion 23. The atomizing electrode 6 is erected, and the dew condensation water generated in the cooling unit 11 is conveyed to the tip of the atomizing electrode 6 by a capillary phenomenon or the like inside the atomizing electrode 6, and a high voltage is generated on the way. A high voltage is applied by the application unit 8, and discharge is performed between the water that has reached the tip of the atomizing electrode 6 and the counter electrode 7, so that the water that reaches the tip of the atomizing electrode 6 can be discharged. The electrostatic atomization is performed sequentially by causing Rayleigh splitting sequentially. Needless to say, it is preferable that condensed water is generated in the atomizing electrode 6 itself together with the cooling part 11 of the Peltier element 10 using the metal atomizing electrode 6. It is also preferable to provide a pipe-shaped water passage that guides water to the tip of the atomizing electrode 6. On the other hand, the heat dissipating part 12 of the Peltier element 10 is provided with heat dissipating fins 24 that face the air passage 18, improving the heat dissipating efficiency from the heat dissipating part 12 of the Peltier element 10, and thus the operating efficiency of the Peltier element 10. Improvements are being made. Specifically, the heat dissipating fins 24 of the present example are disposed in the downstream portion of the air passage 18 that is relatively close to the air blowing fan 19 so that the air flow generated by the air blowing fan 19 can be applied without loss, thereby improving the heat dissipating efficiency. It has been. In addition, the heat transfer part 25 which comprises the heating part 9 of the fragrance | flavor evaporating means 4 mentioned later is also provided in the thermal radiation part 12 of this Peltier device 10.

  As shown in FIG. 2, the fragrance transpiration unit 4 includes a fragrance storage unit 26 that stores a fragrance, and a heating unit 9 that heats the fragrance stored in the fragrance storage unit 26. Here, solid or liquid aroma oil etc. can be used for a fragrance | flavor. Moreover, the heating part 9 of this example is comprised by the heat-transfer member 25, ie, the thermal radiation part 12 of the Peltier element 10, as mentioned above, and the fragrance | flavor accommodating part 26 is attached to this heat-transfer member 25. FIG. When the Peltier element 10 is energized, a heat generation phenomenon occurs in the heat radiating portion 12. At this time, the air blowing passage 5 is not connected to the radiating section 24 of the Peltier element 10. When the heat is not sufficiently dissipated by the air 18, the heat accumulated in the heat radiating portion 12 of the Peltier element 10 is transmitted through the heat transfer member 25 so that the fragrance contained in the fragrance containing portion 26 is evaporated. Has been. Although not shown in the present example, a temperature sensor is installed in the fragrance containing unit 26, and energization control to the Peltier element 10 and heat radiation from the radiation fins 24 are performed via the control unit based on the temperature detected by the temperature sensor. Drive control of the air blowing means 5 is performed, and temperature control of the heating unit 9 suitable for fragrance transpiration is enabled (for example, 50 to 70 ° C.). Although the aroma that has been transpired originally has diffusibility, it is put on the wind generated by the air blowing means 5 and diffused from the exhaust port 17 to the deodorant space, thereby further improving the diffusibility and deodorizing space. Will immediately spread over a wide range of.

  In the deodorizing apparatus 1 having the above-described configuration, the mist generated by the electrostatic atomizing means 3 and the fragrance evaporated by the fragrance transpiration means 4 are the same in the deodorizing space such as the toilet room 15 arranged. It can be dissipated by the air blowing means 5. Therefore, the deodorizing and fragrance effects do not always act after arrangement like conventional deodorants and fragrances, and the electrostatic atomizing means 3 and the fragrance transpiration means 4 are operated together with the blowing means 5 at an appropriate timing. The mist and the fragrance can be quickly spread over the entire deodorizing space by being put on the wind by the air blowing means 5, and the deodorizing and fragrance effect acts on the entire deodorizing space with immediate effect and economy. It is something that can be done. Here, the nanometer-size mist generated by the electrostatic atomizing means 3 is the surface of the wall of the deodorizing space or the object existing in the deodorizing space (for example, the toilet 27 if the deodorizing space is the toilet room 15). Therefore, not only the odor components contained in the air of the deodorant space, but also the odor components attached to the wall 28 of the deodorant space and the objects (for example, the toilet 27) in the deodorant space, The deodorizing effect can be made to work well. Moreover, according to this mist, generation | occurrence | production of the mold | fungi with respect to the wall surface 28 of a deodorizing space or the object (for example, toilet bowl 27) inherent in a deodorizing space can also be prevented. Further, in the deodorizing apparatus 1 having the above configuration, since the mist and the fragrance can be diffused in the deodorizing space by the same air blowing means 5, the apparatus structure is simplified by the combined air blowing means 5. That is, since the deodorizing apparatus 1 is downsized, the arrangement of the deodorizing apparatus 1 in the deodorizing space is facilitated. More specifically, the radiant transpiration means 4 and the radiant evaporation means 4 and the radiating part 12 of the Peltier element 10 used for generating condensed water as the heating part 9 of the fragrance transpiration means 4 are also used. The structure of the electrostatic atomizing means 3 can be shared by the same Peltier element 10 to simplify the structure of the apparatus, and the deodorizing apparatus 1 can be miniaturized. For example, in FIG. 4, a vertically long hand-washing cabinet 29 is embedded in the wall surface 28 of the toilet room 15 which is a deodorizing space. The arrangement of the odor device 1 in the toilet room 15 can be carried out well.

  By the way, in the control part of the deodorizing apparatus 1 of this example, the operation control of the deodorizing apparatus 1 as shown in FIG. 5 can be performed, and thereby the deodorizing apparatus suitable for use in the toilet room 15 is provided. 1 Here, according to the human body detection sensor 13 provided in front of the case 2, the presence or absence of the user in the toilet room 15 which is a deodorizing space can be detected. The control unit operates the fragrance evaporation mode M1, which operates the Peltier element 10 and does not operate the blowing unit 5 and the high voltage application unit 8 of the electrostatic atomizing unit 3, operates the Peltier element 10 and the blowing unit 5, and operates statically. A fragrance diffusion mode M2 in which the high voltage application unit 8 of the electromisting means 3 is not activated, and a mist emission mode M3 in which the high voltage application unit 8 of the Peltier element 10 and the blowing means 5 and the electrostatic atomization means 3 are activated are set. Yes.

  First, when the user's entry into the toilet room 15 is detected by the human body detection sensor 13, the control unit enters the fragrance transpiration mode M1 to energize the Peltier element 10. At this time, the blowing means 5 and the high voltage application section 8 of the electrostatic atomizing means 3 are not operated. In this state, as shown in FIG. 6A, the energized Peltier element 10 absorbs heat in the cooling unit 11 and generates heat in the heat radiating unit 12, but since the blower 5 is not in operation, the radiating fins 24 are used. Most of the heat is not radiated, and the temperature rises at the heat radiating portion 12 of the Peltier element 10, and the transmission member functions effectively as the heating portion 9 of the fragrance transpiration means 4. That is, the fragrance stored in the fragrance storage unit 26 of the fragrance transpiration means 4 is efficiently heated, and the fragrance can be evaporated immediately after the user enters the room. At this time, even if dew condensation water is generated in the cooling unit 11 of the Peltier element 10, the high voltage application unit 8 is not energized, so the mist is not generated in the electrostatic atomizing means 3, that is, the mist is aromatized. The situation that deodorizes is avoided.

  Next, when a predetermined temperature at which the fragrance evaporates is detected by a temperature sensor installed in the fragrance containing section 26, the control section switches to the fragrance diffusion mode M2, and operates the blowing means 5 so that a low air volume is generated. Here, the low air volume means an air volume that does not sufficiently radiate heat from the heat radiation fins 24 to the air in the air passage 18. In this example, a low air flow is obtained as a result of intermittent operation of the blower fan 19, but a low output operation may be performed so as to generate a constant low air flow. In this state, as shown in FIG. 6 (b), the aroma that has transpired is diffused from the exhaust port 17 to the toilet room 15 by the air flow in the air passage 18 with a low air volume generated by the blower fan 19, and the toilet room The feeling of use of the toilet room 15 can be enhanced with respect to 15 users in use. At this time, the Peltier element 10 maintains the energized state, and the high voltage application unit 8 of the electrostatic atomizing means 3 is in an inoperative state. Therefore, in the cooling unit 11 of the Peltier element 10, mist is not generated in the electrostatic atomizing means 3 even if dew condensation water is generated, that is, a situation in which the mist is deodorized is avoided. Thus, the fragrance can be efficiently diffused into the toilet room 15.

  Next, when the human body detection sensor 13 detects that the user after using the toilet room 15 (after the toilet) has left the toilet room 15, the control unit switches to the mist diffusion mode M3, and the air blowing means 5 is switched to the normal air volume. While operating, the high voltage application part 8 of the electrostatic atomization means 3 is operated. At this time, the Peltier element 10 is maintained in an energized state. In this state, as shown in FIG. 6C, in the heat radiating portion 12 of the Peltier element 10, the heat radiating fins 24 are air-cooled by the air flow in the ventilation passage generated by the blower fan 19, that is, the fragrance transpiration means 4. Before the fragrance is heated by the heat transfer member 25 serving as the heating unit 9, the heat radiation from the radiation fins 24 is efficiently performed, and the generation of condensed water in the cooling unit 11 of the Peltier element 10 is promoted, thereby generating electrostatic fog. The mist is stably generated in the activating means 3 and is immediately dissipated to every corner of the toilet room 15 by being put on the air flow generated by the blower fan 19. The deodorizing effect by mist is made to act effectively with respect to the odor component which increases (after stool). In this example, although not shown in the figure, a condensed water storage sensor for detecting the condensed water storage amount is provided in the condensed water receiving portion 23, and the condensed water storage amount has reached a predetermined amount or more by the condensed water storage sensor. When detected, the Peltier element 10 is deenergized to save power, and when the condensed water storage sensor detects that the condensed water storage amount has become a predetermined amount or less, the Peltier element 10 is appropriately selected. In order to secure stable generation of mist in the electrostatic atomizing means 3. In addition, the operation of the deodorizing apparatus 1 in the mist diffusion mode M3 is performed for a certain period of time after the user leaves the toilet room 15, and the subsequent deodorizing apparatus 1 is put into an operation stop state.

  According to the operation control of the control unit described above, the deodorizing apparatus 1 prevents a state where the deodorizing effect and the fragrance effect due to the mist are offset, and gives the fragrance effect to the user who is using the toilet room 15. A deodorizing effect can be applied to odor components that give a good feeling of use and increase after the use of the toilet room 15, that is, the deodorizing effect and fragrance at an appropriate timing according to the usage form of the toilet room 15. The effect can be applied to the toilet room 15 with immediate effect and economy, and the deodorizing apparatus 1 suitable for use in the toilet room 15 can be achieved.

  FIG. 7 shows another example of the embodiment of the present invention. Since this example is an example in which the heating unit 9 of the fragrance transpiration means 4 is changed as compared with the previous example, in the remaining configuration similar to the previous example, the same reference numerals are given and description is omitted, and only the changed part will be described. . That is, the heating unit 9 of the fragrance transpiration unit 4 of the previous example uses heat generated in the heat radiating unit 12 of the Peltier element 10 used for generation of condensed water in the electrostatic atomization unit 3. The heating unit 9 of the fragrance transpiration unit 4 is composed of a heater 14 that can be energized independently of the electrostatic atomization unit 3. More specifically, the fragrance transpiration unit 4 of the present example is accommodated and disposed in a storage chamber 30 formed in the case 2 so as to face and be adjacent to the air passage 18, and the fragrance transpiration unit 4 and electrostatic atomization. The power supply for the means 3 is different. According to this, the operation of the fragrance evaporating means 4 can be performed independently of the operation of the electrostatic atomizing means 3, such as causing the fragrance to be diffused at the same time as the mist, or only fragrance to be diffused. In addition, the operation mode of the deodorizing apparatus 1 can be diversified. In addition, since the transpiration performance of the fragrance is not limited by the performance of the Peltier element 10, for example, the heater 14 of the heating unit 9 has a high output to increase the fragrance evaporation efficiency and increase the fragrance effect on the deodorant space. The range of the apparatus design of the deodorizing apparatus 1 according to the objective, such as improving an immediate effect, can be expanded.
