Description

[Technical Field]

[0001] The present invention relates to a lingering odor control system and process for eliminating lingering odors such as perfumes in indoor spaces such as hotel rooms. [Background technology]

[0002] Recently, due to the increase in inbound demand, the number of guests from overseas at domestic hotels has been increasing. It is known that guests from overseas generally tend to use far more perfume than Japanese guests. As a result, there are many cases where a strong scent of perfume lingers in the guest room after check-out, and the hotel is unable to immediately rent out the room to the next guest, which has become an even greater problem for hotels as inbound demand increases.

[0003] To address this issue, conventional deodorizing treatment using air purifiers alone has proven difficult to eliminate lingering odors, and odors that have permeated guest room furnishings such as curtains, carpets, and beds continue to dissipate, making it difficult to completely eliminate the odors. Because it takes time to eliminate lingering odors, rooms must be left vacant during treatment, resulting in business losses. Therefore, a more effective solution to lingering odors has been desired. For example, the deodorizing device disclosed in Patent Document 1 uses ozone to enhance the deodorizing effect. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2004-305264 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the deodorizing devices that use ozone, the ozone is not only generated and sprayed into the air, but also permeates curtains, etc., for deodorizing treatment, but in reality, when using ozone alone, the smell of ozone is added to the lingering scent of perfume, etc. If humidification is also performed, it is possible to deodorize the lingering scent that has permeated curtains, etc., but the following new problems arise.

[0006] Although ozone can disinfect the air and destroy odors and toxic fumes due to its powerful oxidizing properties, it also poses known health risks to humans. Therefore, special equipment and methods are required to remove ozone from indoor spaces after treatment, which takes a long time, resulting in the rooms being unable to be used immediately and incurring high costs.

[0007] The present invention was made in response to the above-mentioned problems of the prior art, and aims to provide a lingering odor control system and process that can effectively eliminate lingering odors in indoor spaces without incurring high costs. [Means for solving the problem]

[0008] In order to achieve the above-mentioned object, one aspect of the present invention is to provide a method for manufacturing a semiconductor device comprising: A lingering odor countermeasure system for deodorizing lingering odors in an indoor space, a deodorizing treatment means for spraying a mist of atomized deodorizer into an indoor space; and an air purifying means for removing particles including the mist from an indoor space, The deodorizing treatment means is configured to operate for a predetermined first predetermined time, and after the operation of the deodorizing treatment means has stopped and a predetermined second predetermined time has elapsed, the air purifying means is configured to operate for a predetermined third predetermined time. [Effects of the Invention]

[0009] The lingering odor countermeasure system and process of the present invention can effectively eliminate lingering odors in indoor spaces without incurring high costs. [Brief explanation of the drawings]

[0011] Hereinafter, a representative embodiment of the present invention will be described with reference to the drawings. The lingering scent countermeasure system 1 according to this embodiment is a system for deodorizing lingering scents in an indoor space (hereinafter also abbreviated as "this system 1"). The lingering scent countermeasure process according to this embodiment is a method for deodorizing lingering scents in an indoor space by implementing this system 1 (hereinafter also abbreviated as "this process"). Note that the indoor space that is the processing target of this system 1 and this process is an indoor space partitioned into a predetermined size inside various buildings, etc., but in this embodiment, a hotel guest room will be used as a specific example for the following explanation.

[0012] <Overview of Lingering Smell Countermeasure System 1> FIG. 1 is a perspective view showing a specific example of the configuration of the present system 1. As shown in FIG. 1, the present system 1 includes a deodorizing treatment means 10 and an air cleaning means 20. The deodorizing treatment means 10 sprays a mist of atomized deodorant into an indoor space, and is configured, for example, by an existing ultrasonic humidifier (hereinafter also referred to as "ultrasonic humidifier 10"). The air cleaning means 20 removes particles containing the mist from the indoor space, and is configured, for example, by an existing air purifier (hereinafter also referred to as "air purifier 20").

[0013] The system 1 also includes a cart 40 on which the ultrasonic humidifier 10 and the air purifier 20 can be mounted and moved, and a control means 30 (see FIG. 3), which will be described below. Note that the components, shapes, numerical values, etc. shown in this embodiment are examples of the present invention and do not limit the present invention. Also, detailed descriptions of already well-known matters and redundant descriptions of substantially identical configurations may be omitted as appropriate.

[0014] <Regarding the deodorizing means 10 / ultrasonic humidifier 10> The deodorizing treatment means 10 is basically a type of spray device, and spray devices are usually used to humidify or disinfect spaces by spraying water, chlorous acid water, or hypochlorous acid water. In this embodiment, the liquid agent to be sprayed is changed to a deodorizer, making it possible to deodorize even strong lingering scents such as perfume. The spray device that constitutes the deodorizing treatment means 10 is an ultrasonic humidifier 10 that can spray a mist of deodorizer atomized by ultrasonic vibration.

[0015] The configuration of the ultrasonic humidifier 10 is common, so a detailed explanation of the configuration will be omitted, but specifically, for example, a product such as the "Space Sterilization Device DevirusAC" (registered trademark) manufactured by Purgatio Co., Ltd. can be used, and a deodorizer can be used instead of the chemical originally used in this product, chlorus acid water (chlorus disinfecting water).

[0016] This ultrasonic humidifier 10 uses ultrasonic vibrations from an ultrasonic vibrator housed inside a roughly rectangular cylindrical casing to convert the deodorizer supplied from the internal tank into a micro-mist that is quickly sprayed throughout the entire passenger compartment, making use of the deodorizing effects of the deodorizer and dispersing it evenly to curtains and other interior furnishings. Here, micro-mist refers to a fine mist with an average particle size of 0.5 μm, and this product's performance allows it to disperse over a 100-square-meter space in approximately four minutes.

[0017] As shown in Figure 1, ultrasonic humidifier 10 has a casing 11 with a spray nozzle 12 on the top surface thereof, which sprays a mist of atomized deodorant in a predetermined direction, and an operation panel 13 is provided beside spray nozzle 12. Although not shown, operation panel 13 has switches operated by the user, such as a power button and a spray amount adjustment button, and is also configured to be able to display various information.

[0018] Specific examples of deodorizers that can be used in ultrasonic humidifier 10 include "Microgel RED" and "Microgel D-VE" manufactured by Calmor Co., Ltd., or "Grand Bio Air" and "Deodorizing Support Team Y" manufactured by Kai Corporation. While the original target odors of such deodorizers are organic solvents such as toluene and xylene, experiments by the present inventors have confirmed that when used for spraying, they are also effective in eliminating strong lingering scents such as perfume.

[0019] The deodorizing treatment means 10 is not limited to the specific product mentioned above, nor is it limited to a general ultrasonic humidifier, as long as it sprays a mist of atomized deodorizer into the indoor space. The type of deodorizer is also not limited to the specific product mentioned above.

[0020] <About the air cleaning means 20 / air purifier 20> The air cleaning means 20 is basically a type of device that cleans the air by removing particles such as dust and dirt floating in the air, but in this system 1, it mainly removes the deodorant mist that has been sprayed by the ultrasonic humidifier 10 and remains in the air in the guest room. The air cleaning means 20 corresponds to an air purifier 20 that sucks in particles including the deodorant mist along with the air and removes them by adsorbing them onto a filter.

[0021] The configuration of the air purifier 20 is common, so a detailed description of the configuration will be omitted, but specifically, for example, a product such as the "Biomicron Circle PRO BM-S711A" (registered trademark), an air purifier manufactured by Andes Electric Co., Ltd., the applicant of the present application, may be adopted, and the normal OFF timer that is originally equipped on this product may be specially modified to be an ON timer for this system 1.

[0022] This type of air purifier 20 uses a large-diameter turbofan and proprietary ventilation ducts located inside a roughly cylindrical casing to draw air in a spiral pattern from all directions, and is able to remove particles, including mist, from the air by adsorbing them onto a proprietary circle filter.The circle filter here has multiple HEPA filters folded onto the outside of the cylinder to ensure dust collection capabilities, and a porous activated carbon unit attached to the inside of the cylinder to also provide a powerful deodorizing effect.

[0023] A HEPA filter is a high-performance particulate air filter, and JIS standards stipulate that it must have a particle capture rate of 99.97% or more for particles with a particle size of 0.3 μm at the rated airflow. The "Biomicron Circle PRO BM-S711A" used as the air purifier 20 is also equipped with a unit equipped with a titanium oxide photocatalyst and an LED ultraviolet lamp. The air purifying means 20 is sufficient as long as it removes particles, including mist, from the indoor space, and is not limited to the specific products mentioned above, nor is it limited to general air purifiers.

[0024] Furthermore, the "Biomicron Circle PRO BM-S711A" used as the air purifier 20 is normally equipped with an OFF timer that has the function of stopping operation after a preselected set time. However, in this system 1, there is a waiting period after the ultrasonic humidifier 10 stops operating, and then the air purifier 20 needs to be operated at a delayed time to remove mist. Therefore, the OFF timer has been omitted and instead an ON timer function, which will be described later, has been added.

[0025] As shown in Fig. 1, an air outlet 22 that blows purified air in all directions along the periphery is provided on the top surface of a casing 21 of air purifier 20, and an operation panel 23 is provided inside air outlet 22. As shown in Fig. 2, operation panel 23 is provided with switches operated by the user, such as a power button 231, a mode button 232, a timer button 233, a display pattern switch button 234, an information switch button 235, and an airflow level switch button 236. Operation panel 23 also has an information display section 237 that displays various types of information and a warning display section 238.

[0026] The power button 231 is a switch for turning the air purifier 20 on and off. The mode button 232 is a switch for switching the operating state of the air purifier 20 between modes such as manual and auto, and in the present embodiment, manual is selected, which allows operation at any air volume level. In this manual mode, the air volume level can be adjusted by touching and swiping the air volume level switching button 236. Here, in the present embodiment, the air volume level is selected as High, at the right end of the arc, as the maximum air volume.

[0027] Timer button 233 is a switch for arbitrarily selecting in advance the time at which air purifier 20 starts operating using the function of the ON timer. The ON timer is configured so that by selecting a time, such as 1 hour, 2 hours, or 4 hours, in advance, air purifier 20 starts operating after the set time. That is, if 1 hour, for example, is selected using timer button 233, air purifier 20 is set to operate after 1 hour. Note that the operation start times of 1 hour (1 hour), 2 hours (2 hours), and 4 hours (4 hours) are merely examples, and the configuration may be such that even shorter times can be selected.

[0028] The display pattern switching button 234 is a switch that switches the luminous color of the airflow level switching button 236 to each display color pattern. In this embodiment, two display color patterns are prepared, for example, eight colors and a single blue color. The information switching button 235 is a switch that switches the information displayed on the information display unit 237 to one of temperature, humidity, and PM2.5. The airflow level switching button 236 is a switch that adjusts the blown airflow, as described above.

[0029] Information display unit 237 is composed of, for example, a 7-segment LED or a liquid crystal panel, and displays a countdown of the time selected by timer button 233. That is, in air purifier 20, power is turned on (ON) by power button 231, the operation start time of the ON timer is set by timer button 233, manual is set by mode button 232, maximum air volume is set by air volume level switching button 236, and then power is turned off (OFF) by power button 231, and when power is turned off, a countdown starts from 60 minutes → 59 → ... → 2 → 1 minute.

[0030] The countdown of the ON timer is configured to be displayed sequentially as numbers on the information display unit 237. When the countdown displayed on the information display unit 237 reaches 0 (zero), the air purifier 20 starts operating with the settings at the time of the previous power OFF. After the air purifier 20 starts operating, various operations are the same as normal operations of the original product. If the power button 231 is pressed during the countdown of the ON timer, the timer is reset and normal operation is performed. The details of the operation of the air purifier 20 described above are merely an example.

[0031] <Regarding the control means 30> Fig. 3 is a block diagram showing a schematic configuration of the present system 1. As shown in Fig. 3, the present system 1 includes an ultrasonic humidifier 10, an air purifier 20, and a control means 30. The control means 30 of this embodiment mainly has the function of operating the ultrasonic humidifier 10 for a predetermined first predetermined time, and then operating the air purifier 20 for a predetermined third predetermined time after a predetermined second predetermined time has elapsed since the operation of the ultrasonic humidifier 10 stopped.

[0032] Such control means 30 includes at least an OFF timer 15 that operates the ultrasonic humidifier 10 for a first predetermined time, and the aforementioned ON timer 25 that starts operation of the air purifier 20 after the second predetermined time has elapsed. The ultrasonic humidifier 10 also includes a control board 14 that controls its operation, and the air purifier 20 also includes a control board 24 that controls its operation, although some of its functions overlap with those of the control means 30. The "first predetermined time" for operating the ultrasonic humidifier 10, the "second predetermined time" that is a standby time, and the "third predetermined time" for operating the ultrasonic humidifier 10 will be described in detail below.

[0033] If the ultrasonic humidifier 10 itself does not have an OFF timer that automatically stops operation after a preset time has elapsed, a commercially available OFF timer 15 can be attached, and this OFF timer 15 can be set to stop operation and turn off when the first predetermined time has elapsed, and then connected to a power source. On the other hand, the air purifier 20 is equipped with the above-mentioned ON timer 25, and is set to start operation when the sum of the first predetermined time and the second predetermined time has elapsed, and to operate for at least the third predetermined time.

[0034] If the OFF timer is omitted and the ON timer is installed instead, air purifier 20 will continue to operate unless the user performs a stop operation. This type of specification does not pose any particular problems, and if you want to automatically stop operation after the third predetermined time has elapsed, you can leave the OFF timer that was originally included in the product, or you can add a commercially available OFF timer, as with ultrasonic humidifier 10 described above.

[0035] The control means 30 may be configured by control boards 14, 24 built into the ultrasonic humidifier 10 and air purifier 20, including the functions of each timer. Furthermore, as shown by the imaginary line (two-dot chain line) in Figure 3, an external controller 31 may be added to configure a control means capable of collectively controlling the ultrasonic humidifier 10 and air purifier 20. Here, the controller 31 is a microcomputer (microcomputer) composed of a CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory), etc. The control boards 14, 24 and the controller 31 are connected to each other wirelessly or via wires so that they can communicate with each other.

[0036] <About Cart 40> The system 1 is optionally equipped with a cart 40 on which the ultrasonic humidifier 10 and air purifier 20 are placed as a unit. As shown in Figure 1, the cart 40 has a base 41 formed in the shape of a thick rectangular plate in a plan view, with casters 42 attached to the four corners of the bottom surface of the base 41, allowing it to be easily moved around on the floor. A handle 43 is fixed upright on one short side of the base 41, and detachable fences 44 are attached upright on the other short side and both long sides of the base 41.

[0037] Additionally, dolly 40 may be provided with accessories such as an instruction manual for dolly 40 itself, as well as fasteners such as rubber bands or belts for temporarily fixing ultrasonic humidifier 10 and air purifier 20 placed on base 41 so that they do not move. As shown in Figure 1, ultrasonic humidifier 10 and air purifier 20 are placed side by side and adjacent to each other within fence 44 on base 41 of dolly 40.

[0038] <Function of lingering odor countermeasure system 1 and lingering odor countermeasure process> Next, the operation of the lingering odor countermeasure system 1 according to this embodiment will be explained, focusing on the lingering odor countermeasure process. This system 1 includes an ultrasonic humidifier 10, an air purifier 20, and a dolly 40 as product units. When using the system, first assemble the dolly 40 according to the instruction manual. Then, as shown in Figure 1, the ultrasonic humidifier 10 and the air purifier 20 are placed side by side on the base 41 of the assembled dolly 40.

[0039] At this time, it is advisable to use rubber bands or belts attached to dolly 40 to hang around the center of the top surface of ultrasonic humidifier 10 and air purifier 20, with the hooks on both ends hooked onto the underside of fence 44. This allows ultrasonic humidifier 10 and air purifier 20 to be stably fixed on dolly 40. Therefore, the user can easily grab handle 43 and move ultrasonic humidifier 10 and air purifier 20 together with dolly 40 to the hotel room to be treated, and start operating them immediately in that state.

[0040] The ultrasonic humidifier 10 is set on the cart 40 so that the spray direction from the spray nozzle 12 (shown by the white arrow in Figure 1) faces away from the adjacent air purifier 20. This arrangement allows the mist sprayed from the ultrasonic humidifier 10 to be sprayed effectively without interfering with the air purifier 20, and to be diffused evenly throughout the passenger compartment. Note that within the passenger compartment, the ultrasonic humidifier 10 and the air purifier 20 are each supplied with alternating current from a power outlet within the passenger compartment.

[0041] Once the system 1 is ready to operate in a guest room where a lingering perfume scent is being emitted, the ultrasonic humidifier 10 and the air purifier 20 are operated sequentially. That is, in this process, the ultrasonic humidifier 10 is first operated for a predetermined first predetermined time, and after the operation of the ultrasonic humidifier 10 stops, a predetermined second predetermined time passes, and then the air purifier 20 is operated for a predetermined third predetermined time.

[0042] Figure 4 is a timing chart showing a specific example of this process. In Figure 4, signal line a10 indicates the ON / OFF state of the ultrasonic humidifier 10, and signal line b20 indicates the ON / OFF state of the air purifier 20. In the first "deodorizing step" by operating the ultrasonic humidifier 10, the power is turned ON via the operation panel 13 of the ultrasonic humidifier 10, and the first predetermined time is set to, for example, 20 minutes using the OFF timer 15.

[0043] Furthermore, when the operation of the ultrasonic humidifier 10 begins, the timer button 233 on the operation panel 23 of the air purifier 20 is used to select 1 hour from the end of operation of the ultrasonic humidifier 10, taking into account the second predetermined time in the "standby step," for example, 40 minutes, and is preset so that the humidifier will turn on and start operating 60 minutes later. Note that the third predetermined time in the "air purification step" by the operation of the air purifier 20 is, for example, at least 60 minutes, but as mentioned above, there is no particular need to automatically stop the operation of the air purifier 20 at that point.

[0044] As an example of this process, the first predetermined time in the "deodorizing step" by first operating the ultrasonic humidifier 10 is 20 minutes, the second predetermined time in the "waiting step" from when the ultrasonic humidifier 10 stops operating until the air purifier 20 starts operating is 40 minutes, and the third predetermined time in the "air purification step" by operating the air purifier 20 is at least 60 minutes, so that one cycle is completed in 2 hours.

[0045] The two-hour total duration for one cycle mentioned above was determined based on the hotel's request that it normally take two hours to prepare a guest room, and based on the experimental results described below, if the guest room area is up to 50 square meters, it is usually sufficient to perform one cycle using only one set of this system 1. However, if the guest room area to be treated exceeds 50 square meters, if the room has an unusual layout, or if the lingering odor is strong, two or more sets of this system 1 may be used, or if there is time, this process may be repeated two or more times.

[0046] <<Deodorization step>> In the deodorizing step, the ultrasonic humidifier 10 is activated to atomize the deodorizer with ultrasonic vibrations, creating a micro-mist that is sprayed into the guest room. This ensures that the mist is evenly dispersed not only to the odorous components that cause lingering odors in the air, but also to the curtains and other furnishings in the guest room, thereby reliably deodorizing any odorous components adhering to the furnishings. Experimental results, described below, have confirmed that a first predetermined time of about 20 minutes is sufficient for guest rooms up to 50 square meters in size for this deodorizing step.

[0047] <<Wait step>> After the deodorizing step is completed, i.e., after the operation of ultrasonic humidifier 10 is stopped by OFF timer 15, a standby time is set to further enhance the deodorizing effect while utilizing the deodorizing effect of the deodorizer remaining in the guest room. During this time, air purifier 20 also stops operating. Experimental results described below have confirmed that the second predetermined time for this standby step is approximately 40 minutes, twice the first predetermined time, for guest rooms up to 50 square meters in size.

[0048] <<Air purification step>> Even after the standby step described above is completed, particles containing mist are still floating in the passenger compartment because the previous deodorizing step sprayed a fine mist of 0.5 μm particles. Therefore, to ensure the removal of such particles, air purifier 20 is operated at delayed intervals. Here, air purifier 20 is turned on and begins operation by ON timer 25 described above, a total of one hour after the start of operation of system 1, i.e., the start of operation of ultrasonic humidifier 10.

[0049] In the air purification step, air purifier 20 is activated to suck in particles containing deodorant mist along with the air and remove them by adsorbing them onto a filter. This prevents mist from remaining in the air in the guest room, further enhancing safety. Experimental results described below have confirmed that the third predetermined time for this air purification step is approximately 60 minutes, which is three times the first predetermined time, or 1.5 times the second predetermined time, for guest rooms up to 50 square meters in size.

[0050] In the air purification step, there is no need to actively stop the operation of air purifier 20 after the third predetermined time has elapsed; there is no particular problem if air purifier 20 continues to operate. Furthermore, if air purifier 20 is equipped with a unit equipped with, for example, a titanium oxide photocatalyst and an LED ultraviolet lamp, it can not only remove particles from the air using a filter, but also decompose and remove harmful substances in the air through the photocatalytic action, and deodorize. This completes the deodorizing treatment in the guest room using this system 1 and this process.

[0051] <Experiments on this system 1 and this process> The inventors conducted experiments to confirm the effectiveness of the deodorizing treatment for lingering perfume scents in guest rooms of various sizes at Hotel Chinzanso Tokyo, including a 60 square meter suite where a strong lingering perfume scent was detected, with only relevant personnel present.

[0052] The specific configuration of the system 1 used in this experiment was as follows: the ultrasonic humidifier 10 mentioned above was the "Space Sterilization Device DevirusAC" manufactured by Purgatio Co., Ltd.; the deodorizer was the "Deodorizer Offcent LD-A04L" manufactured by Andes Electric Co., Ltd.; and the air purifier 20 was the "Biomicron Circle PRO BM-S711A" air purifier manufactured by Andes Electric Co., Ltd., with the above-mentioned ON timer 25 added.

[0053] The results of this experiment showed that in a guest room up to 50 square meters in area, performing one cycle of this process according to the timing chart shown in Figure 4 completely eliminated any lingering perfume scent in the guest room, preventing any subsequent return of the scent. Furthermore, not only was the lingering scent of perfume removed, but the odor levels also reduced to an undetectable level for cigarette smoke and deodorant, demonstrating that this system 1 and this process are effective not only in deodorizing the odor components that cause lingering perfume scents, but also in eliminating various odor components other than lingering scents.

[0054] <Configuration and effects of the present invention> Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments. The present invention derived from the above-described embodiments will be described below.

[0055] First, the present invention provides a lingering odor countermeasure system 1 for deodorizing lingering odors in an indoor space, a deodorizing treatment means 10 for spraying a mist of atomized deodorizer into an indoor space; and an air purifying means (20) for removing particles including the mist from the indoor space. The deodorizing treatment means 10 is configured to operate for a predetermined first predetermined time, and after the operation of the deodorizing treatment means 10 has stopped and a predetermined second predetermined time has elapsed, the air cleaning means 20 is configured to operate for a predetermined third predetermined time.

[0056] With this lingering odor countermeasure system 1, the inventors of the present application, after numerous experiments and extensive research, discovered that by operating the deodorizing treatment means 10 and the air purification means 20 at special time intervals, it is possible to effectively eliminate lingering odors in a room space without increasing costs, and thus completed the present invention. In particular, this solves the problem that the operation of conventional air purifiers alone can only remove odorous components from the air that passes through, and it also becomes possible to reliably remove odorous components adsorbed on curtains and other surfaces in the guest room.

[0057] In addition, according to the present invention, the deodorizing treatment means 10 is configured by an ultrasonic humidifier 10 capable of spraying a fine mist obtained by atomizing a deodorizing agent by ultrasonic vibration, The air cleaning means 20 is characterized by being constituted by an air cleaner 20 that sucks in particles including the mist together with the air and removes them by adsorbing them onto a filter. By combining the ultrasonic humidifier 10 and the air purifier 20 in this manner, it becomes possible to more reliably deodorize lingering odors in the indoor space.

[0058] The present invention also provides a control means 30 for controlling the operation of each of the ultrasonic humidifier 10 and the air purifier 20, The control means 30 includes at least a timer 15 that operates the ultrasonic humidifier 10 for the first predetermined time; The air purifier is characterized by including a timer 25 that starts operation of the air purifier 20 after the second predetermined time has elapsed.

[0059] The combination of timer 15 and timer 25 of control means 30 allows the ultrasonic humidifier 10 and air purifier 20 to be operated at their respective timings with ease and with a simple configuration. In addition to controlling them using the timer functions of the individual devices, they may also be configured to be controlled simultaneously or individually by a single controller (mainly by turning the devices on and off).

[0060] The present invention is also characterized in that the ultrasonic humidifier 10 and the air purifier 20 are mounted on a movable cart 40 to form a unit. This allows the ultrasonic humidifier 10 and the air purifier 20 to be easily moved together with the cart 40 to the indoor space to be treated, and can be immediately put into operation in that state.

[0061] Furthermore, the present invention provides a lingering odor countermeasure process for deodorizing lingering odors in an indoor space, comprising: a deodorizing step of spraying a mist of atomized deodorizer into an indoor space for a first predetermined time; The method is characterized by including an air purification step in which, after a waiting time which is a predetermined second predetermined time after the deodorizing treatment step is completed, particles including the mist are removed from the indoor space for a predetermined third predetermined time.

[0062] According to this lingering odor countermeasure process, lingering odors in an indoor space can be effectively deodorized without being limited by the specific configuration of the entire lingering odor countermeasure system 1 and without incurring high costs.

[0063] Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions that do not deviate from the gist of the present invention are also included in the present invention. For example, the indoor space that is the target of treatment by this system 1 and this process is not limited to hotel rooms as long as it is a space that can be closed off, but can also be used for deodorizing various indoor spaces, such as restaurants, hospital rooms, offices, and guest rooms of various vehicles (railroad cars, airplanes, ships, etc.). [Industrial Applicability]

[0064] The lingering odor control system and process of the present invention can be used to deodorize a variety of indoor spaces, not just hotel rooms, but also restaurants, hospital rooms, offices, and rooms in various vehicles (railroad cars, airplanes, ships, etc.). [Explanation of symbols]
