Description

  The present invention relates to a humidifying device that allows air to pass through a vaporizing element that has sucked up water in a water receiving portion to form humidified air and discharge the air to the outside.

Conventionally, in this type of humidifier, in order to prevent the humidified air contaminated with various germs from being released to the outside, the degree of contamination of the water in the water receiving part due to long-term use, etc. was detected and detected. When the contamination level is equal to or higher than a predetermined contamination level, the operation is stopped (for example, see Patent Document 1). In this technique, a pair of electrodes are mounted apart in the water receiving portion, a voltage is applied between the electrodes, and the current flowing between the pair of electrodes is measured with an ammeter, and contamination of the water based on the measured current value. The degree is detected.
Japanese Patent Laid-Open No. 5-60370 (page 3)

  In the technique of Patent Document 1, the contamination state of the humidified air released to the outside is determined by the degree of contamination of the water receiving portion. However, only the contamination of the water receiving portion makes the humid air unsanitary. Not the cause but also the contamination of the vaporizing element. Therefore, there is a possibility that contaminated humidified air may be released simply by determining the degree of contamination of the water receiving portion. In addition, when detecting the degree of water contamination, the detection is performed using a pair of electrodes mounted in the water receiving portion, so that the detection accuracy decreases when the electrode surface becomes dirty. There is a problem that the humidified air may be released.

  This invention is made in view of such a point, and it aims at providing the humidification apparatus which can always discharge | release clean humid air, without releasing the humid air contaminated with various germs. .

  A humidifier according to the present invention includes a water supply tank, a water receiving portion that receives and stores water from the water supply tank, a vaporizing element that holds water under the water in the water receiving portion, and intake air from the suction port. A fan that discharges the humidified air to the outside from the air outlet, and a suspended particle detector that detects the number of airborne particles in the humidified air before being released to the outside from the air outlet; Control means for controlling the drive of the fan, and the control means stops the operation of the fan when the detection result of the suspended particle detector is equal to or greater than a predetermined number of suspended particles.

  According to the present invention, the number of suspended particles in the humidified air before being discharged from the outlet is detected, and when the detection result is equal to or greater than the predetermined number of suspended particles, the fan operation is stopped. It is possible to always release clean humidified air without releasing humidified air contaminated with bacteria or the like.

Embodiment 1 FIG.
FIG. 1 is a schematic cross-sectional view showing a schematic configuration of a humidifying device according to Embodiment 1 of the present invention.
The humidifier 1 is fixed to the humidifier body 2, the water receiver 3 provided in the lower part of the humidifier body 2, the water supply tank 4 that supplies water to the water receiver 3, and the water receiver 3. A certain amount of the lower part is immersed in the water in the water receiver 3, and a vaporizing element 5 for holding the water and a fan 8 are provided. The fan 8 sucks in air from a suction port 6 provided in the humidifying device main body 2, uses the sucked air as humidified air through the vaporizing element 5, and discharges the humidified air from the air outlet 7 to the outside. The humidifier 1 further includes a suspended particle detector 9, a display unit 10 that is disposed on the upper surface of the humidifier main body 2 and serves as a notification unit, and a controller 11 that controls the entire humidifier 1.

  The suspended particle detector 9 is disposed between the fan 8 and the air outlet 7 provided in the humidifying device main body 2, and is suspended in the humidified air before being blown from the fan 8 and discharged from the air outlet 7 to the outside. The amount of particles is detected. Specifically, the amount of airborne microbes floating in the humidified air and airborne particles such as dust, dust, and pollen is detected. The detection result of the suspended particle detector 9 is output to the control device 11. The suspended particle detector 9 is specifically composed of a DNA sensor, a dust concentration meter, and the like. In the first and second embodiments, the case where the suspended particle detector 9 is composed of a DNA sensor will be described. A case where the densitometer is configured will be described in a third embodiment.

FIG. 2 is a block diagram showing an electrical configuration of the humidifier of FIG.
The control device 11 includes a microprocessor (MPU), includes a RAM and a ROM (both not shown), and controls the entire humidifier 1 according to a program stored in the RAM and ROM. A fan 8, a display unit 10 and a suspended particle detector 9 are connected to the control device 11, and the fan 8 and the display unit 10 are controlled according to the detection result output from the suspended particle detector 9.

FIG. 3 is a schematic cross-sectional view of a main part when a DNA sensor is used as a suspended particle detector.
The DNA sensor 21 has a configuration in which a semiconductor substrate 23 is attached to a resin substrate 22. The DNA sensor 21 irradiates visible light on the semiconductor substrate 23 and measures the current value flowing on the surface of the semiconductor substrate 23 with an ammeter 24. Then, the number of bacteria having a specific DNA is measured. The measurement principle is that when a specific DNA is immobilized on the surface of the substrate 23 and bacteria having the DNA adhere, the current value increases. Alternatively, the captured bacterial DNA may be issued with a fluorescent dye, and the amount of luminescence may be detected.

  A plurality of rectifying plates 25 are provided between the fan 8 and the DNA sensor 21 at substantially equal intervals in a direction substantially parallel to the air flow. The humidified air blown from the fan 8 may become turbulent until it is discharged from the blowout port 7, and when it becomes turbulent, the amount of air passing through the DNA sensor 21 becomes unstable, and stable detection is possible. Cannot be done. Therefore, a plurality of rectifying plates 25 are provided to rectify the air passing through the DNA sensor 21. As a result, the air volume distribution between the fan 8 and the outlet 7 is made uniform, and stable detection can be performed.

FIG. 4 is a flowchart showing a control operation of the humidifying device common to the first to third embodiments. Hereinafter, the operation of the humidifier 1 will be described with reference to FIG.
In the humidifier 1, the water in the water supply tank 4 is supplied to the water receiver 3, the lower part of the vaporizing element 5 is immersed in the water receiver 3, and the vaporizing element 5 vaporizes the water in the water receiver 3. The element 5 is held from the bottom to the top. When an operation switch (not shown) is turned on, the control device 11 operates the fan 8 (S1). Thereby, the air sucked by the fan 8 passes through the vaporizing element 5 and becomes humidified air, and is discharged to the outside from the blowout port 7. When the operation switch (not shown) is turned on, the suspended particle detector 9 is also operated (S2). The suspended particle detector 9 detects the number of suspended particles contained in the humidified air, and the detection result is indicated by the control device 11. Output to.

The control device 11 determines whether or not the detection result from the suspended particle detector 9 is equal to or larger than a predetermined number of suspended particles (S3). It is judged that the state is bad, and the operation of the fan 8 is stopped (S4), and for example, the display unit 10 notifies that the cleaning of the humidifying device 1 is urged (S5). When the suspended particle detector 9 is the DNA sensor 21, the predetermined number of suspended particles is set to, for example, 10 ⁴ particles / mL which is an odor threshold value. When the detection result is equal to or greater than the odor threshold value, the fan 8 Stop driving.

  In addition, the factor which deteriorates the sanitary condition of humidified air is that water in the water receiver 3 is left unused for a long period of time, contamination of the water receiver 3 itself, and the vaporizing element 5 The hygienic condition of the entire humidifying device 1 is related to dirt. In the prior art, the contamination state of the water in the water receiving part 3 is judged and the operation is stopped when the contamination state is bad. However, if the water is simply replaced and renewed, the vaporizing element 5 is temporarily contaminated. Even if it is, driving will be resumed. In this case, the contaminated humidified air is released to the outside.

  On the other hand, in this Embodiment 1, the sanitary state of the humidified air before being discharged from the outlet 7 is judged, and when the sanitary state is bad (that is, when the detection result is equal to or greater than the predetermined number of suspended particles). Since the operation of the fan 8 is stopped, humid air with poor hygiene condition is not released to the outside, and is released to the outside only when the hygiene condition is clean. Therefore, it is possible to reliably prevent germs and the like from being scattered outside the apparatus.

  In addition, since the user is informed that the maintenance is urged, the user can know the cleaning timing of cleaning the water receiving portion 3 and replacing the vaporizing element 5. In addition, although the example which displays on the display part 10 was shown here as alerting | reporting that a maintenance is encouraged, it is not restricted to this, You may sound a buzzer. This also applies to the embodiments described later.

Embodiment 2. FIG.
The second embodiment shows another configuration example of the DNA sensor 21 constituting the suspended particle detector 9. Other configurations are the same as those of the first embodiment, and hereinafter, the second embodiment will be described focusing on portions different from the first embodiment.

FIG. 5 is an enlarged view of a main part of the characteristic part of the second embodiment and is a diagram illustrating another configuration example of the DNA sensor. Fig.5 (a) is a top view of the blower outlet part of a humidification apparatus main body, FIG.5 (b) is a principal part schematic sectional drawing containing a blower outlet part. In FIG. 5, the same parts as those in FIG.
As shown in FIG. 5A, the air outlet 7 of the humidifying device 1 is formed in a lattice shape with a plurality of air outlets 7a provided in the main body 2 of the humidifier. In the second embodiment, a DNA sensor 21 is provided integrally with the blowing port 7 portion. That is, the detection unit of the DNA sensor 21 has a configuration including the resin substrate 22 and the semiconductor substrate 23 as described above, and the humidifier body 2 is made of resin. For this reason, the resin substrate 22 of the DNA sensor 21 is also used as the blowing port 7 portion of the humidifying device body 2, and the semiconductor substrate 23 is attached to the resin substrate 22. The semiconductor substrate 23 has substantially the same opening shape as the blowout port 7 and is formed in a lattice shape.

  In the second embodiment, the same effect as that of the first embodiment can be obtained by the configuration as described above, and the resin substrate 22 of the DNA sensor 21 is also used as a part of the humidifying device body 2. Compared with the configuration shown in FIG. 3, the resin substrate 22 dedicated to the DNA sensor 21 is not required, and the configuration is simplified. Further, in the configuration of FIG. 3, since the DNA sensor 21 is disposed in the flow path between the fan 8 and the blowout port 7 so as to block the air flow, there is a possibility of air resistance and obstruction of the air flow. However, in the configuration of FIG. 5, the DNA sensor 21 is configured in the same shape as the shape of the air outlet 7, so that the air flow is not obstructed.

  In addition, although the structure which affixed the semiconductor substrate 23 on the humidifier main body 2 itself was demonstrated here, the blower outlet 7 part of the humidifier main body 2 is formed with the resin-made panel which can be attached or detached with respect to the humidifier main body 2. FIG. In this case, the semiconductor substrate 23 may be attached to this panel.

Embodiment 3 FIG.
In the first embodiment and the second embodiment, the DNA sensor 21 is used as the suspended particle detector 9, but the third embodiment uses a dust concentration meter. Other configurations are the same as those in the first embodiment, and the following description will focus on the differences of the third embodiment from the first embodiment.

FIG. 6 is an enlarged view of the main part of the characteristic part of the third embodiment, and is an enlarged view of the part between the fan and the outlet. In FIG. 6, the same parts as those in FIG.
The dust concentration meter 30 automatically measures the density according to the change in the amount of transmitted light of the light beam. If the detection result of the dust concentration meter 30 is, for example, 0.15 g / cm ³ or more, which is the building management standard value, it is judged that the humidified air is in a poor sanitary condition, and the fan 8 is stopped and maintained. Inform the user that he / she wants to
Thus, also when the suspended particle detector 9 is comprised by the dust concentration meter 30, the effect similar to Embodiment 1 can be obtained.

Embodiment 4 FIG.
In the first to third embodiments, the number of suspended particles in the humidified air is detected, and when the detection result is equal to or greater than the predetermined number of suspended particles, the operation is stopped and notified. In Embodiment 4 and Embodiment 5 described later, an antibacterial agent is disposed in the water receiving portion 3 or the water supply tank 4, the remaining antibacterial performance of the antibacterial agent is detected, and the operation is performed when the antibacterial performance is lower than the predetermined performance. It is intended to stop and notify.

FIG. 7 is a schematic cross-sectional view showing a schematic configuration of the humidifying device of the fourth embodiment. FIG. 8 is an enlarged cross-sectional view of the main part of FIG. FIG. 9 is a block diagram illustrating a schematic configuration of the humidifying device according to the fourth embodiment. 7 to 9, the same parts as those in FIGS. 1 and 2 are denoted by the same reference numerals.
The humidifying device 1 according to Embodiment 4 includes an antibacterial agent container 40 at the bottom of the water receiver 3, and the antibacterial agent 41 for preventing the generation of germs in the water in the antibacterial agent container 40. Is housed. Further, an antibacterial performance detector 50 that detects the remaining antibacterial performance of the antibacterial agent 41 and outputs the detection result to the control device 11 is provided.

  Here, the antibacterial agent 41 of the fourth embodiment is obtained by kneading an antibacterial powder into a substrate such as a resin or glass, and a metallic pigment such as cobalt is attached to the antibacterial powder. ing. Accordingly, the antibacterial agent 41 has a colored appearance as a whole, and has the property that its own color becomes lighter as the antibacterial component elutes into water and the antibacterial performance of the antibacterial agent 41 itself decreases. ing. For this reason, the remaining antibacterial performance of the antibacterial agent 41 can be determined by the color intensity of the antibacterial agent 41. Therefore, the antibacterial performance detector 50 according to the fourth embodiment includes a color difference meter 51 that detects the color of the antibacterial agent 41 based on the color difference or reflection spectrum of the antibacterial agent 41.

  As shown in FIG. 8, the color difference meter 51 includes a light emitter 52 that emits light toward the antibacterial agent 41 and a light receiver 53 that receives reflected light from the antibacterial agent 41, and enters the light receiver 53. The color of the antibacterial agent 41 is determined based on the reflected light. In addition, the water receiving part 3 shall be comprised with the transparent member so that the light from the light-emitting device 52 may permeate | transmit.

FIG. 10 is a flowchart showing the operation of the humidifying device common to the fourth embodiment and the fifth embodiment described later.
When an operation switch (not shown) is turned on, the control device 11 first operates the antibacterial performance detector 50 (S11) and acquires the detection result from the antibacterial performance detector 50 before operating the fan 8. . Then, the acquired detection result is compared with a predetermined antibacterial performance set in advance, and if the detection result is lower than the predetermined antibacterial performance (S12), the display unit prompts maintenance without operating the fan 8. 10 (S13). Since the color difference meter 51 is used as the antibacterial performance detector 50 in the fourth embodiment, when the detection result of the color difference meter 51 is lower than a predetermined saturation, it is determined that the remaining antibacterial performance is lower than the predetermined antibacterial performance. .

  Thus, in Embodiment 4, when the remaining antibacterial performance of the antibacterial agent 41 is detected and the remaining antibacterial performance is sufficiently left, the sanitary level of the water in the water receiver 3 is maintained. This makes it possible to release clean humid air.

Embodiment 5 FIG.
In the fourth embodiment, the color difference meter 51 is used as the antibacterial performance detector 50 for detecting the antibacterial performance of the antibacterial agent 41. However, in the fifth embodiment, a reflectance meter is used. Other configurations are the same as those of the fourth embodiment, and the following description will focus on the differences of the fifth embodiment from the fourth embodiment.

FIG. 11 is a diagram illustrating a characteristic portion of the fifth embodiment, and is a diagram illustrating an example in which a reflectometer 61 is used as the antibacterial performance detector 50.
In the fifth embodiment, similarly to the fourth embodiment, an antibacterial agent containing portion 40 is provided at the bottom of the water receiving portion 3. The antibacterial agent containing portion 40 is different from the fourth embodiment in the antibacterial agent containing portion 40. Is housed. The antibacterial agent 42 according to the fifth embodiment is a completely soluble antibacterial agent mainly composed of phosphate, silicate, and the like. When the antibacterial component is eluted from the antibacterial agent 42 into the water, the volume of the antibacterial agent 42 is reduced. Has the property of gradually decreasing. Here, the remaining antibacterial performance is determined by the remaining amount of the antibacterial agent 42.

  Here, a reflectometer 61 is used as a detection means for detecting the remaining amount of the antibacterial agent 42. The reflectometer 61 includes a light emitter 62 that emits light toward the antibacterial agent 42 and a light receiver 63 that receives the reflected light from the antibacterial agent 42, and the amount of reflected light incident on the light receiver 63. Based on the above, the remaining amount of the antibacterial agent 42 is determined. That is, if the remaining amount of the antibacterial agent 42 is large, the reflectance of the antibacterial agent 42 is high, and the amount of reflected light received by the light receiver 63 is increased. The light passes through the antibacterial agent 42 as shown by the dotted arrow in FIG. 11, and the amount of light received by the light receiver 63 is reduced. Based on this, the remaining amount of the antibacterial agent 42 is determined, and when the remaining amount is lower than the predetermined amount, it is determined that the remaining antibacterial performance is lower than the predetermined antibacterial performance.

  The fifth embodiment configured as described above can obtain the same functions and effects as those of the fourth embodiment. In the fourth embodiment and the fifth embodiment, the antibacterial agents 41 and 42 are provided in the water receiving portion 3. However, the remaining antibacterial agents 41 and 42 in the water supply tank 4 are provided in the water supply tank 4. The same control may be performed by detecting the performance.

Embodiment 6 FIG.
When the sanitary condition in the humidifier 1 is deteriorated, a phenomenon such as a decrease in the humidification amount may appear. In the sixth embodiment, a decrease in humidification amount is detected to control operation / stop of the fan 8.

Explained.

  As described above, the sanitary condition in the humidifying device 1 is lowered and the contaminated humidified air is released. As described above, the water in the water receiving portion 3 is not used for a long period of time. In addition, there are dirt on the water receiver 3 itself, and dirt on the vaporizing element 5. When dust, mold, or the like adheres to the vaporizing element 5, the water absorption of the vaporizing element 5 deteriorates, or the amount of humidification decreases due to clogging and a reduction in air volume. In Embodiment 6, in place of the suspended particle detector 9 of Embodiment 1 shown in FIG. 1, a humidifying amount detecting means for detecting the humidifying amount is provided, and the operation is performed when the detection result is lower than the predetermined humidifying amount. Along with stopping, a notification is given to encourage maintenance.

  As the humidification amount detection means, means for detecting the amount of water level change in the water receiver 3 per unit time is used. Specifically, for example, as shown in FIG. 12, an ultrasonic sensor 70 is provided to detect a change in the height position of the water surface of the water receiver 3. And when the amount of water level change per unit time is lower than the predetermined amount of water level change, it judges that the sanitary condition in the humidification apparatus 1 is bad, and performs operation stop and alert | report. In addition to this, for example, a change in the weight of the water receiver 3 may be detected, or a change in the air volume may be detected.

  Here, since the humidified air is generated by the air sucked from the suction port 6 passing through the vaporizing element 5, it is very important to keep the vaporizing element 5 clean in order to obtain clean humidified air. is there. In Embodiment 6, it is possible to grasp the deterioration of the sanitary condition of the vaporizing element 5 from the decrease in the humidification amount, and when the cleanliness of the vaporizing element 5 is not sufficient, the operation is stopped. It is possible to prevent germs and the like from being scattered outside the apparatus.

  Further, since the vaporizing element 5 sucks up the water in the water receiving portion 3, the sanitary condition of the vaporizing element 5 is also affected by the contamination of water in the water receiving portion 3. Therefore, in the sixth embodiment, it becomes possible to accurately grasp the sanitary condition in the humidifying device 1 as compared with the case of simply detecting only the dirt of the water in the water receiving portion 3 as in the conventional case. Operation control is possible after accurately determining the sanitary condition in the device 1. Accordingly, it is possible to reliably prevent germs and the like from being scattered outside the apparatus, and it is possible to always release clean humid air.

  In the first to third embodiments, the configuration using the suspended particle detector 9 is shown, and in the fourth and fifth embodiments, the configuration using the antibacterial performance detector 50 is shown, and the sixth embodiment is further described. In the above, the configuration using the humidification amount detection means has been described, but a configuration in which these are combined as appropriate may be used. For example, it is set as the structure provided with both the floating particle detector 9 and the antibacterial performance detector 50, for example, it is set as the structure provided with both the floating particle detector 9 and the antibacterial performance detector 50, When the detection result is equal to or greater than the predetermined number of suspended particles, or when the detection result of the antibacterial performance detector 50 is lower than the predetermined antibacterial performance, the operation of the fan 8 may be stopped and notified.
