Description

  The present invention relates to a humidifier.

  Conventionally, a humidifier is widely used to humidify indoor air by vaporization of water. Patent Document 1 discloses an example of such a vaporization type humidifier.

  The conventional humidifying device described in Patent Document 1 includes a main body having a rectangular box-like outer shape and opening a suction port and an outlet, a blower, and a vaporization filter whose lower end is immersed in water of a water tank. This humidifier allows the dry air in the room sucked into the interior of the main body from the suction port by the blower to pass through the evaporation filter wetted by the water in the water tank and blows it out from the blowout port. Thereby, indoor air can be easily humidified.

JP, 2014-47963, A

  However, the conventional humidifying device described in Patent Document 1 has a rectangular box-like outer shape of the main body casing and has a relatively thin shape in the front-rear direction, so it tends to tip over in the front-rear direction. When this humidifier falls over in the front-back direction, the entire front or back perpendicular to the floor receives a strong impact when it falls over, and the impact itself causes the housing itself, the electronic components inside, and the blades of the fan. It has been a problem that vehicles and the like are likely to suffer mechanical damage.

  The present invention is made in view of the above-mentioned point, and an object of the present invention is to provide a humidifying device capable of suppressing the occurrence of mechanical damage at the time of falling and improving the safety against the damage. .

  In order to solve the above-mentioned subject, the humidifying device of the present invention comprises: a case which opens a suction port and a blowout port; and a fan duct which is formed in the inside of the case and connects the suction port and the blowout port. An air blower disposed in the air blow duct to generate an air flow in the air blow duct, a humidifying unit humidifying an air flow flowing in the air blow duct, and a water storage tray disposed in the humidifying portion; The present invention is characterized in that it has a protrusion whose outer shape protrudes laterally outward from at least one side wall of the substantially rectangular box, and a part of the air duct consists of an internal space of the protrusion.

  According to this configuration, for example, when the humidifying device placed on the floor falls over so that the side wall provided with the protrusion is on the bottom, compared with the side wall forming the vertical, as compared with the case without the protrusion. The protrusions come in contact with the floor at an early timing. Thereby, the speed at the time of the contact to the floor of the side wall in which the projection part was provided is reduced compared with the case where there is no projection part, and the impact which a humidification apparatus receives at the time of fall is eased. Furthermore, since a part of the air duct is constituted by the internal space of the projecting portion, water spilled from the water storage tray is stored in the portion of the projecting portion when the humidifying device falls over. Thus, the water spilled from the water storage tray does not reach the electronic components inside the housing.

  Further, in the humidifying device with the above configuration, the outer shape of the protrusion is formed by a curved surface.

  Further, in the humidifying device of the above configuration, the suction port is formed in the projecting portion.

  In the humidifier of the above configuration, the volume of the internal space of the protrusion is larger than the water storage amount of the water storage tray.

  Further, in the humidifying device of the above configuration, the projection has a double structure having an outer wall and an inner wall, and the outer wall is made of a transparent member.

  According to the configuration of the present invention, it is possible to reduce the impact that the humidifying device receives when falling, and to suppress the occurrence of mechanical damage of the humidifying device. Furthermore, it is possible to prevent water spilled from the water storage tray from reaching the electronic components inside the housing when the humidifying device falls over, and it is possible to suppress the occurrence of electrical damage of the humidifying device. Further, the capacity of the water storage tray can be increased while maintaining a thin design in the humidifying device, and a sufficient amount of water can be held in the water storage tray.

First Embodiment
First, an outline of the structure of the humidifying device according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 7. 1 and 2 are a front view and a side view of the humidifying device. FIG.3 and FIG.4 is the perspective view seen from the front side and back side of a humidification apparatus. FIG. 5 is a vertical sectional side view of the humidifying device. 6 and 7 are vertical sectional perspective views seen from the front side and the back side of the humidifying device. In addition, the white arrow drawn on drawing shows the distribution channel and distribution direction of the air flow which generate | occur | produces with a fan.

  The humidifying device 1 includes a housing 2 having a substantially rectangular box shape as shown in FIGS. 1 to 4. The housing 2 is provided with an air suction port 3 opened in the back surface 2b and an air flow outlet 4 opened in the upper surface 2c. The suction port 3 is disposed on the upper side of the back surface 2b of the housing 2, and a dust collection filter (not shown) is provided. The blower outlet 4 is disposed on the right side of the top surface 2c of the housing 2 when the humidifying device 1 is viewed from the front side, and a louver 4a is provided. The housing 2 is internally provided with a blower duct 5, an ion generator 6, a blower 20 and a humidifying unit 30.

  The air duct 5 is formed inside the housing 2 to allow the suction port 3 and the blowout port 4 to communicate with each other. The blower 20 and the humidifying unit 30 are disposed on the flow path of the air flow of the blower duct 5. As shown in FIG. 5, the air duct 5 extends downward along the back surface 2 b immediately inside the back surface 2 b of the housing 2 in which the suction port 3 is formed, and reaches the location of the humidifying portion 30. Furthermore, the air duct 5 extends upward along the front surface 2 a from the placement position of the humidifying unit 30 immediately inside the front surface 2 a of the housing 2 to the placement position of the blower 20. The blower outlet 4 is disposed above the blower 20.

  The ion generator 6 is disposed downstream of the blower 20 in the air circulation direction. The ion generator 6 includes a positive ion generating unit and a negative ion generating unit (both not shown). The positive ion generation unit includes a positive discharge electrode (not shown), and the negative ion generation unit includes a negative discharge electrode (not shown). The two pairs of positive discharge electrodes and negative discharge electrodes are each formed in a needle shape and arranged at predetermined intervals, and are provided facing the inside of the air duct 5.

The ion generator 6 supplies the high voltage generated by the high voltage electricity generation circuit to the positive discharge electrode and the negative discharge electrode to generate a discharge to release ions. Here, a voltage composed of an alternating current waveform or an impulse waveform is applied to the positive discharge electrode and the negative discharge electrode of the ion generator 6. A positive voltage is applied to the positive discharge electrode, and hydrogen ions by corona discharge combine with moisture in the air to generate positive ions mainly composed of H ⁺ (H ₂ O) m. The negative discharge electrode negative voltage is applied, oxygen ions by corona discharge moisture combined with mainly O ₂ in air ^- generating negative ions consisting of (H ₂ O) n. Here, m and n are arbitrary natural numbers. H ⁺ (H ₂ O) m and _{^{O 2 - (H 2 O)}} n surrounds these aggregated on the surface of airborne bacteria and odor components in the air.

Then, as shown in the formulas (1) to (3), by collision, [· OH] (hydroxyl radical) and H ₂ O ₂ (hydrogen peroxide) which are active species are aggregated and formed on the surface of a microorganism or the like. Destroy airborne bacteria and odorous components. Here, m 'and n' are arbitrary natural numbers. Therefore, the ion generator 6 releases the air flowing through the inside of the air duct 5 so as to contain positive ions and negative ions generated by the discharge at the positive and negative discharge electrodes, for example, in the room. It can be sterilized and deodorized.

_{^{H + (H 2 O) m}} + O 2 - (H 2 O) n → · OH + 1 / 2O 2 + (m + n) H 2 O ··· (1)
_{^{H + (H 2 O) m}} + H + (H 2 O) m '+ O 2 - (H 2 O) n + O 2 - (H 2 O) n'
→ 2 · OH + O ₂ + (m + m '+ n + n') H ₂ O (2)
_{^{H + (H 2 O) m}} + H + (H 2 O) m '+ O 2 - (H 2 O) n + O 2 - (H 2 O) n'
→ H ₂ O ₂ + O ₂ + (m + m '+ n + n') H ₂ O (3)

  In the present embodiment, positive ions and negative ions are generated by the ion generating device 6, but only positive ions or only negative ions may be generated.

  Further, the ions described here also include charged fine particle water. At this time, the ion generating device 6 is an electrostatic atomizing device, and charged fine particle water containing a radical component is generated by the electrostatic atomizing device. That is, condensation water is generated on the surface of the discharge electrode by cooling the discharge electrode provided in the electrostatic atomizer with a Peltier element. Next, when a negative high voltage is applied to the discharge electrode, charged particulate water is generated from the condensation water. The discharge electrode also generates negative ions released into the air together with the charged fine particle water.

  The ion generator 6 may be an electrostatic atomizer that generates either positive ions or negative ions, and particulate water charged to the opposite polarity of the positive ions or negative ions. In addition to sterilization and deodorization of the room, it is also considered that a relaxation effect is produced when negative ion or negatively charged particulate water is generated.

  The blower 20 includes, for example, a sirocco fan 22 rotationally driven by a fan motor 21. The blower 20 is disposed closer to the air outlet 4 than the humidifying unit 30 of the air duct 5. The blower 20 generates an air flow in the air duct 5 in a direction to blow the air sucked into the inside of the housing 2 from the suction port 3 to the humidifying unit 30.

  Incidentally, on the outer peripheral side wall portion of the downstream portion of the sirocco fan 22 in the air flow direction, ion generation holes (not shown) in which the positive discharge electrode and the negative discharge electrode of the ion generator 6 face the air flow space are provided corresponding to the number of electrodes Be For example, when the ion generator 6 includes one positive discharge electrode and one negative discharge electrode, two ion generation holes are individually provided corresponding to the respective electrodes.

  The humidifying unit 30 is disposed upstream of the blower 20 in the air flow direction with respect to the blower duct 5. The humidifying unit 30 humidifies the air flowing through the air duct 5 using the vaporization of water. After the air humidified by the humidifying unit 30 passes through the blower 20, the air is blown out from the blowout port 4 to the outside of the housing 2.

  In the present embodiment, the blower 20 is disposed downstream of the humidifying unit 30 in the air flow direction. However, the present invention is not limited to this arrangement, and the blower 20 may be disposed upstream of the humidifying unit 30. Also good. In this case, after the air sucked into the inside of the housing 2 by the rotation of the air blower 20 passes through the air blower 20, the air is humidified by the humidifying unit 30 and blown out from the outlet 4 to the outside of the housing 2.

  The humidifying part 30 is provided with the water storage tray 31, the humidification filter 32, and the water supply tank 33, as shown to FIGS.

  The water storage tray 31 is provided at the lower part of the housing 2. A part of the outer shape of the water storage tray 31 constitutes a part of the back surface 2 b of the housing 2, and the water storage tray 31 can be attached to and detached from the housing 2 from the rear of the humidifying device 1. The water storage tray 31 is divided into two regions of the humidification filter installation unit 34 and the water supply tank installation unit 35. The humidification filter installation part 34 is located inside the air flow duct 5, and the water supply tank installation part 35 is located outside the air flow duct 5. A water flow hole through which the humidification filter installation unit 34 and the water supply tank installation unit 35 are communicated with partition walls (not shown) for dividing the humidification filter installation unit 34 and the water supply tank installation unit 35 into each other. Is provided.

  The humidification filter 32 is detachably installed in the humidification filter installation portion 34 of the water storage tray 31. The humidifying filter 32 is formed of, for example, a non-woven fabric, and the lower part thereof is immersed in the water stored in the water storage tray 31 to absorb water. The air flowing through the air duct 5 passes through the upper portion of the humidification filter 32, and is humidified by the vaporization of water at this time.

  The water supply tank 33 is detachably installed in the water supply tank setting portion 35 of the water storage tray 31. The water supply tank 33 is, for example, in the form of a vertically-long form formed of a transparent synthetic resin, and is disposed upright with the water supply port (not shown) provided on the cap 33 a down so that its longitudinal direction is substantially vertical. . The water supply port communicates with the water supply tank setting portion 35 of the water storage tray 31, and the water in the water supply tank 33 is replenished to the water storage tray 31 by the action of gravity. The water supply tank 33 is sealed except for the water supply port. The water supply tank 33 is provided with a water supply valve (not shown) at the water supply port. The water supply valve is formed of, for example, a valve using a spring, and automatically adjusts the water level WL (the amount of water storage) of the water storage tray 31 to a constant value according to the principle of Torricelli.

  The water supply tank 33 is inserted from the upper side of the housing 2 and stored in a tank storage portion 7 provided inside the housing 2. A light irradiator 36 made of a light transmitting member is provided on the side wall 7 a of the tank housing 7. Furthermore, a tank LED (Light Emitting Diode) 37 is provided at a location at which the light irradiation unit 36 is separated from the tank storage unit 7. The tank LED 37 is disposed to emit light toward the water supply tank 33 through the light irradiator 36. The humidifier 1 can notify the amount of water in the water supply tank 33 from a window 2 m described later provided on the front surface 2 a of the housing 2 by reflecting the light emitted from the tank LED 37 with the water inside the water supply tank 33. The water amount of the water supply tank 33 can be detected by providing a weight sensor or the like below the water supply tank 33.

  An operation panel 8 is disposed at a substantially central portion in the lateral direction of the top surface 2 c of the housing 2. The operation panel 8 is provided with a plurality of operation buttons such as an operation button, a reset button, and a timer button. In addition, the operation panel 8 is provided with a plurality of lamps such as an operation display lamp and a water supply lamp. A control board 9 for controlling the operation of the humidifying device 1 is provided below the operation panel 8.

  The humidifying device 1 includes a power supply substrate 10 provided on the back side inside the housing 2, a power cord 11 connected to the power supply substrate 10 and extending to the outside of the housing 2, and not shown provided at the tip of the power cord 11. And a power plug. The humidifying device 1 operates by receiving power supply from a commercial AC power supply via the power supply substrate 10, the power cord 11, and the power plug.

  A temperature / humidity sensor (not shown) provided on the temperature / humidity sensor substrate 12 is disposed above the back surface 2 b of the housing 2. The temperature and humidity sensor detects the temperature and humidity outside the housing 2, that is, the room through the vent 2 d provided on the back surface 2 b of the housing 2. The humidifying device 1 adjusts the amount of humidification based on the temperature and humidity detected by the temperature and humidity sensor.

  Subsequently, the detailed configuration of the casing 2 of the humidifying device 1 will be described using FIGS. 8 to 10 in addition to FIGS. 1 to 7. FIG. 8 is an explanatory view relating to the color of the window portion of the humidifying device 1. FIG.9 and FIG.10 is a side view which shows the state at the time of fall of the humidification apparatus 1, and after fall.

  As described above, the housing 2 of the humidifying device 1 has a substantially rectangular box shape in outer shape, and has a relatively thin shape in the front-rear direction. Then, protrusions 2e and 2f are provided on the front surface 2a and the back surface 2b of the housing 2, respectively.

  The protrusion 2 e protrudes laterally (forward) from the substantially vertical surface of the front surface 2 a of the housing 2 outward. The protrusion 2 f protrudes laterally (rearward) from the substantially vertical surface of the back surface 2 b of the housing 2 outward. The protrusions 2e and 2f each form a circular joint when viewed from the front side or the back side of the humidifying device 1 and the joint portion with the substantially vertical surface of the front surface 2a of the housing 2 or the substantially vertical surface of the back surface 2b It forms with the curved surface (dome shape) which constitutes a part of. A circle, which is a joint between the projecting portions 2e and 2f and the front surface 2a or the back surface 2b of the housing 2, has a smaller area than a square forming the front surface 2a or the back surface 2b of the housing 2.

  The ratio of the length of the circle, which is the joint between the protrusions 2e and 2f and the front 2a or the back 2b of the housing 2, and the height of the front 2a or the back 2b of the housing 2, is approximately 3: 4. It is in a relationship. In addition, when the humidifying device 1 is viewed from the left and right (see FIGS. 2 and 5), the rectangular box-shaped portion of the housing 2 excluding the protruding portions 2 e and 2 f at the vertical center of the humidifying device 1 The ratio of the thickness and the overall thickness of the housing 2 including the portions of the projecting portions 2e and 2f is in a relationship of approximately 1: 1.1 to 1: 1.8. In addition, when the humidifying device 1 is viewed from the left and right (see FIG. 5), with regard to the protrusions 2e and 2f that look like arcs, a junction with the substantially vertical surface of the front 2a of the housing 2 or the substantially vertical surface of the back 2b. The tangents L1 and L2 at the lower end of each of the two are inclined relative to the substantially vertical surface of the front surface 2a or the substantially vertical surface of the back surface 2b. The external angles α and β of the inclined protrusions 2e and 2f form obtuse angles.

  As shown in FIG. 5, an air inlet 3 is formed in the projection 2 f of the back surface 2 b of the housing 2. And a part of air duct 5 consists of interior space of projection parts 2e and 2f. Thus, the protrusion 2 f secures a sufficiently wide air circulation space until the air sucked from the suction port 3 is sent to the humidifying unit 30. Furthermore, the projecting portion 2 e secures a sufficiently wide air circulation space until the air having passed through the humidifying portion 30 is sent to the blower 20.

  The protrusion 2e of the front surface 2a of the housing 2 has a double structure having an outer wall 2g and an inner wall 2h. The double-layered outer wall 2g is made of a transparent member. Then, a part of the air duct 5 is formed of the internal space of the protrusion 2 e (the space inside the inner wall 2 h of the double structure). A light display 2k and a window 2m are formed on the inner wall 2h of the double structure.

  The light display portion 2k is disposed at the central portion of the protrusion 2e having a circular shape when viewed from the front side. The light display unit 2k includes a front LED 2n whose light can be viewed from the front side of the humidifying device 1 inside the inner wall 2h of the protrusion 2e. The humidifying device 1 can display information such as indoor humidity or humidifying condition of the device by color using the front LED 2n.

  The window portion 2 m is disposed radially outside the light display portion 2 k of the projecting portion 2 e having a circular shape when viewed from the front side, and is disposed at a position corresponding to the water supply tank 33. A part of the water supply tank 33 is visible from the outside of the housing 2 in the window 2m. It is possible to check the amount of residual water in the water supply tank 33 from the outside of the housing 2 by using the window 2 m.

  For example, as shown in FIG. 8, the humidification device 1 can express the humidification state of the indoor air in a state where the water in the water supply tank 33 decreases, using the window 2 m and the tank LED 37. For example, the humidifying device 1 can express the present standard of humidity at the time of humidifying operation with five colors from purple which shows the state in which the room is sufficiently moistened to orange which shows the dried state. Further, for example, the drained state of the water supply tank 33 can be expressed in red, and the ion alone operation can be expressed in gray. In this manner, the humidifying device 1 can express the humidifying state and the operating state of the air in the room by the illumination of seven colors.

  Here, consider the case where the humidifying device 1 placed on the floor falls in the front-rear direction. As shown in FIG. 9, when the humidifying device 1 falls forward, it protrudes earlier and at an earlier timing than the substantially vertical surface of the front surface 2 a of the housing 2 as compared to the case without the protruding portion 2 e. Part 2e contacts the floor. Thereby, the speed at the time of the contact to the floor of front 2a of case 2 reduces compared with the case where there is no projection part 2e, and the shock which humidification device 1 receives at the time of fall is eased.

  Further, as shown in FIG. 10, when the humidifying device 1 falls over, the water W spilled from the water storage tray 31 is stored in the portions of the projecting portions 2e and 2f. As seen in FIGS. 5 to 7, the control substrate 9, the power supply substrate 10, the temperature / humidity sensor substrate 12, the front LED 2 n, and the tank LED 37 are inside the projecting portions 2 e and 2 f (from the substantially vertical surface of the front surface 2 a or the back surface 2 b Is also located inside). Thus, the water W spilled from the water storage tray 31 does not reach the electronic components inside the housing 2. It is desirable that the volume of the internal space of the protrusions 2e and 2f be larger than the amount of water stored in the water storage tray 31, because the safety is enhanced.

  Moreover, the capacity | capacitance of the water storage tray 31 can be made to be able to maintain the thin design of the humidification apparatus 1 by providing the protrusion parts 2e and 2f of the said structure in the humidification apparatus 1. FIG. This makes it possible to hold the water storage tray 31 with a sufficient amount of water (the water level WL in FIG. 5).

Second Embodiment
Next, a humidifier according to a second embodiment of the present invention will be described with reference to FIG. FIG. 11 is a schematic side view of the humidifying device. Since the basic configuration of this embodiment is the same as that of the first embodiment described above, the same reference numerals as in the first embodiment are attached to the components common to the first embodiment and the description thereof is omitted. I assume.

  The humidifying device 1 according to the second embodiment includes protrusions 2e and 2f on the front surface 2a and the back surface 2b of the housing 2 as shown in FIG.

  In the protrusions 2e and 2f of the second embodiment, the joint portion with the substantially vertical surface of the front surface 2a of the housing 2 or the substantially vertical surface of the back surface 2b forms a circular shape when viewed from the front side or the back side of the humidifying device 1. The outer shape is formed by a curved surface (dome shape) which constitutes a part of a ball. The diameter of a circle which is a joint between the projecting portions 2e and 2f and the front surface 2a or the back surface 2b of the housing 2 is substantially the same as the height of the front surface 2a or the back surface 2b of the housing 2.

  In this case, when the humidifying device 1 falls forward or backward, the front surface 2a or the back surface 2b of the housing 2 can more gently contact the floor. Therefore, as compared with the first embodiment, the impact received by the humidifying device 1 at the time of falling is further alleviated.

Third Embodiment
Next, a humidifying device according to a third embodiment of the present invention will be described with reference to FIG. FIG. 12 is a schematic side view of the humidifying device. Since the basic configuration of this embodiment is the same as that of the first embodiment described above, the same reference numerals as in the first embodiment are attached to the components common to the first embodiment and the description thereof is omitted. I assume.

  As shown in FIG. 12, the humidifying device 1 of the third embodiment is provided with protrusions 2e and 2f on the front surface 2a and the back surface 2b of the housing 2, respectively.

In the protrusions 2e and 2f of the third embodiment, the joint portion with the substantially vertical surface of the front surface 2a of the housing 2 or the substantially vertical surface of the back surface 2b forms a rectangular shape when viewed from the front side or the back side of the humidifying device 1. And are formed in a trapezoidal shape when viewed from the side. Also in this embodiment, since the protrusions 2e and 2f are inclined, that is, at an obtuse angle, at the lower end of the joint portion with the substantially vertical surface of the front surface 2a of the housing 2 or the substantially vertical surface of the back surface 2b Once in contact with the inclination of the projection, the impact upon falling can be reduced.

Furthermore, also in this case, the same operation and effect as those of the first and second embodiments can be obtained.

  As in the first to third embodiments, the humidifying device 1 according to the present embodiment includes the housing 2 that opens the suction port 3 and the blowout port 4, and the suction port 3 that is formed inside the housing 2. A blower duct 5 communicating with the blower outlet 4, a blower 20 disposed in the blower duct 5 to generate an air flow in the air blower duct 5, a humidifying unit 30 humidifying the air flow flowing through the air blower duct 5, a humidifying unit 30 And a water storage tray 31 disposed. The housing 2 is provided with projections 2e and 2f which laterally project outward from the front and rear surfaces 2a and 2b of the substantially rectangular box shape, and a part of the air duct 5 is an internal space of the projections 2e and 2f. It consists of

  According to this configuration, for example, when the humidifying device 1 placed on the floor falls over so that the front surface 2a of the housing 2 provided with the projecting portion 2e is downward, as compared with the case where the projecting portion 2e is absent The protrusion 2e comes in contact with the floor earlier than and at an earlier timing than the substantially vertical surface of the front surface 2a. Thereby, the speed at the time of contact to the floor of front 2a in which projection 2e was provided can be reduced compared with a case where there is no projection 2e. Therefore, it is possible to relieve the impact which humidification device 1 receives at the time of fall, and to control generating of mechanical breakage of humidification device 1. Furthermore, since a part of the air duct 5 is formed by the internal space of the protrusions 2e and 2f, the water W spilled from the water storage tray 31 when the humidifying device 1 falls falls is stored in the portions of the protrusions 2e and 2f. As a result, the water W spilled from the water storage tray 31 can be prevented from reaching the electronic components inside the housing 2, and the occurrence of the electrical damage of the humidifying device 1 can be suppressed. Thus, it is possible to provide the humidifying device 1 in which the safety against breakage is improved.

  Moreover, as for the humidification apparatus 1, the external shape of protrusion part 2e, 2f is formed by the curved surface.

  According to this configuration, it is possible to further reduce the impact that the humidifying device 1 receives at the time of falling. Therefore, it is possible to heighten the effect which controls generating of mechanical failure of humidification device 1.

  Moreover, as for the humidifying apparatus 1, the suction inlet 3 is formed in the protrusion part 2f.

  According to this configuration, it is possible to ensure a sufficiently wide air circulation space until the air sucked from the suction port 3 is sent to the humidifying unit 30. Thereby, it is possible to improve the humidification efficiency by the humidification device 1.

  Further, in the humidifying device 1, the volume of the internal space of the protruding portions 2 e and 2 f is larger than the water storage amount of the water storage tray 31.

  According to this configuration, it is possible to improve the function of preventing the water W spilled from the water storage tray 31 from reaching the electronic components inside the housing 2 when the humidifying device 1 falls over. Therefore, it is possible to heighten the effect which controls generating of electric failure of humidification device 1.

  The humidifying device 1 has a double structure in which the projections 2e and 2f have the outer wall 2g and the inner wall 2h, and the outer wall 2g is made of a transparent member.

  According to this configuration, it is possible to obtain a visual effect that the thickness (depth) in the front-rear direction of the humidifying device 1 looks relatively thin. Therefore, it is possible to reduce the feeling of pressure that may be felt when installing the humidifying device 1 indoors.
