  In a humidifier equipped with such a water tank part, it is difficult to insert the water tank part so as to keep it horizontal due to its longitudinal shape, and the water tank part fluctuates during insertion, or the water tank part is accommodated in the humidifier body. When it hits the inner wall of the water tank housing part, the insertion may become unstable, and when there is water in the water tank part, it may spill from the water tank part. In order to insert the water tank part in a stable posture, the bottom of the water tank housing part is provided with a step that is one step higher in the depth direction from the insertion port of the water tank part to support the tip of the water tank part from below, Although there is one that keeps the posture substantially horizontal, there has been a problem that the tip of the water tank part hits the rising surface of this step and gets caught during insertion, and it cannot be inserted smoothly.

  Therefore, as shown in FIG. 6, a chamfered portion is provided at the front end of the water tank portion that abuts the inner wall of the water tank housing portion, or the water tank portion can be smoothly inserted by making the shape narrower toward the front end. However, in the state in which the water tank part having such a shape is mounted, a gap is generated between the water tank part and the inner wall of the water tank housing part. When a gap is generated between the water tank part and the inner wall of the water tank housing part, air is likely to flow in the gap having a smaller pressure loss than the air blowing path passing through the vaporization filter. As a result, air leaks to other than the air blowing path through this gap, so that the air is discharged into the room without passing through the vaporization filter, resulting in a decrease in humidification efficiency. From the above, it has been a challenge to achieve both ease of insertion of the water tank and improvement of humidification efficiency.

  The present invention is to solve the above-mentioned problems, and can be smoothly and stably inserted without being caught when the water tank portion is inserted. Further, when the water tank portion is mounted, the water tank portion is sucked into the main body. It is an object of the present invention to provide a humidifier that can pass air through a vaporization filter without waste and exhibit high humidification efficiency.

  The present invention is a water tank portion that is detachably mounted from an insertion port provided in the main body, has a longitudinal shape in the insertion / removal direction to the main body, and has an exterior surface that is wider in the vertical direction than the opening of the insertion port. A blower that blows air to a blower path that communicates between the suction port and the blower outlet, a vaporization filter that is installed in the blower path in a state where a lower part is immersed in water stored in a fixed amount in the water tank part, and the water tank part In a humidifying device including a water tank housing portion provided with a step that is one step higher in the depth direction from the insertion port side on the bottom surface, a rising surface of the step of the water tank housing portion is inclined, and the water tank portion is In the mounted state, the front end surface of the water tank unit and the innermost surface of the water tank housing unit are in contact with each other so as not to form a gap.

  BEST MODE FOR CARRYING OUT THE INVENTION The best mode of the present invention, which is considered preferable, will be briefly described by showing the effects of the present invention.

  The humidifying device of the present invention inclines the rising surface of the step of the water tank housing portion, and the front surface of the water tank portion in the insertion direction and the innermost surface of the water tank housing portion do not have a gap when the water tank portion is mounted. It is made to contact | abut. In other words, the step is provided with an inclination so as not to get caught when the water tank part is inserted, and further, when the water tank part is mounted, the gap other than the ventilation path through which the air passes can be closed. It is.

  When the water tank part is long in the insertion / removal direction, the tip end side in the insertion direction is inclined downward and may be inserted into contact with the bottom surface of the water tank housing part, but the water tank part is caught by the step being inclined. Can be inserted smoothly without any problems. In addition, there is no need to make a shape that is easy to insert, such as providing a chamfered portion on the front end surface of the water tank portion, so that there is no gap when the shape of the front end surface of the water tank portion is in contact with the innermost surface of the water tank housing portion Therefore, the air sucked into the main body is passed through the vaporization filter without waste and humidified, so that high humidification efficiency can be obtained.

  In addition, since the water tank part exterior surface closes the insertion port while the water tank part is attached to the main body, it is possible to prevent the air blown from the humidifier main body to the outside. Can be passed without waste. Furthermore, since the joint between the insertion port and the water tank portion exterior surface is hidden, the appearance quality of the humidifying device is not deteriorated.

Furthermore, since the power cord is routed from the lowermost surface of the humidifier, the center of gravity of the humidifier can be stabilized and the humidifier main body can be prevented from falling over.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is an external perspective view of a humidifier according to the present invention. The humidifier has a main body front frame 1 a that forms the front and side front portions of the main body 1, and a main body rear frame 1 b that forms the rear and rear sides of the main body 1. The top surface of the main body 1 is humidified in the main body 1. A blower outlet 2 for discharging the humidified air into the room, an operation unit 3 provided with operation switches and the like, and a tank cover 4 that opens and closes when a water supply tank (not shown) is attached to and detached from the main body 1 are provided.

  An insertion port 5 is provided in the lower part of the side surface of the main body 1, and a water tank housing part 7 serving as a space for housing the water tank unit 6 is formed in the lower part of the main body 1 through the insertion port 5. The water tank portion 6 is formed to have a longitudinal shape in the insertion / removal direction with respect to the main body 1 and is detachably attached to the water tank housing portion 7 from the insertion port 5. The water tank 6 is provided with a vaporization filter 8 that absorbs and wets water supplied from a water supply tank (not shown), and passes room air taken in from a suction port (not shown) provided on the back of the main body 1 to the vaporization filter 8. As a result, the water in the water tank 6 is vaporized and discharged from the outlet 2 as humidified air.

  FIG. 2 is a top view (a) and a side view (b) of the water tank 6 when the vaporizing filter 8 is installed. The inside of the water tank section 6 is partitioned by a partition plate 9 erected from the bottom surface, and a vaporization filter storage section 10 in which a vaporization filter 8 is installed on the front end side in the insertion direction to the water tank storage section 7 is on the front side. A water supply tank accommodating portion 11 to which a water supply tank (not shown) is attached is defined. The partition plate 9 is formed higher than the height of the vaporization filter 8. The vaporization filter 8 has a substantially rectangular parallelepiped shape, and is disposed such that the side surface of the vaporization filter 8 is in contact with the water tank portion front end surface 12 and the partition plate 9. Furthermore, a holding piece 13 for restricting the movement of the vaporizing filter 8 is provided on the water tank front end surface 12 and the partition plate 9. When the vaporizing filter 8 is installed, the holding piece 13 is used as a mark. Insert inside from above.

  The upper end of the water tank part exterior surface 14 that forms a part of the side surface of the main body 1 in the state where the water tank part 6 is mounted is formed higher than the height of the partition plate 9 and is formed below the water tank part exterior surface 14. The lower end of the water tank part handle 15 is formed so as to protrude below the bottom surface of the water tank part 6. For this reason, when the water tank part 6 is placed on a horizontal plane, the water tank part 6 is tilted downward in the insertion direction by the amount that the water tank part handle 15 protrudes.

  FIG. 3 is a cross-sectional configuration diagram of the water tank accommodating portion 7. At the upper side and the lower side of the opening of the insertion port 5, the insertion port step portions 16 a and 16 b are bent so as to slightly enter the water tank housing part 7 from the side surface of the main body 1, and when the water tank unit 6 is attached to the main body 1. The upper end of the water tank portion exterior surface 14 abuts the insertion port step portion 16a, and the lower end of the water tank handle 15 contacts the insertion port step portion 16b, thereby closing the insertion port 5. Thereby, since the water tank part exterior surface 14 hides the slight clearance gap of the joint of the water tank part 6 and the insertion port 5, the inside of a humidifier cannot be seen from a joint, and the external appearance quality of a humidifier is not deteriorated.

  On the bottom surface of the water tank housing portion 7, a step is provided which becomes higher when entering the depth direction from the insertion port 5, and the rising surface 17 of this step is inclined. In addition, this level | step difference supports the water tank part front end surface 12 from the bottom when inserting the water tank part 6, and is provided in order to keep the attitude | position of the water tank part 6 which tends to incline to the front end side of an insertion direction substantially horizontal. . In the innermost part of the water tank housing part 7, there is a water tank housing part innermost surface 18 with which the water tank part front end surface 12 abuts when the water tank part 6 is mounted.

  FIG. 4 is a vertical cross-sectional configuration diagram of the humidifier when the water tank unit 6 is mounted. A blower case 20 communicating with the blower outlet 2 is attached around the blower 19, and the blower case outer wall surface 21 and the partition plate 9 of the water tank unit 6 form substantially the same surface. Thereby, the inside of the main body 1 is partitioned into two spaces by the blower case outer wall surface 21 and the partition plate 9, a blower passage space 22 in which the blower 19 is disposed and a water supply tank storage space 23 in which a water supply tank (not shown) is stored. In the air passage space 22, an air passage through which air passes in the order of a suction port (not shown) provided on the back surface of the main body 1, the vaporization filter 8, the blower 19, and the air outlet 2 is formed via the air blowing case 20. Moreover, since the water tank part front end surface 12 is contact | abutting to the water tank accommodating part innermost surface 18, and the shape of the water tank part front end surface 12 is comprised along the water tank accommodating part innermost surface 18, the water tank part 6 mounting | wearing state Then, there is no gap between the water tank front end surface 12 and the water tank housing innermost surface 18.

  A power cord attaching portion 24 for fixing a power cord (not shown) is provided at a lower portion of the place where the bottom surface of the water tank housing portion 7 is raised one step higher, and the lower space formed by raising the bottom surface of the water tank housing portion 7 is effectively used. I use it. Furthermore, since the power cord is routed from the lowermost surface of the humidifier by the power cord attachment portion 24, the center of gravity of the humidifier is stabilized. For example, even when the foot is caught on the power cord, the humidifier falls over. It becomes a structure difficult to do.

  Next, the process of inserting the water tank unit 6 in the humidifying device having the above configuration will be described with reference to FIG. When inserting the water tank part 6 into the main body 1, the water tank part 6 is inserted into the water tank housing part 7 so as to slide from the insertion port 5. Since the water tank part 6 has a longitudinal shape in the insertion / removal direction, and the water tank part handle 15 protrudes below the bottom surface of the water tank part 6, the distal end side in the insertion direction is inclined downward. When the water tank unit 6 is inserted in this posture, the lower surface of the water tank unit 6 comes into contact with the bottom surface of the water tank housing unit 7, and the water tank unit front end surface 12 comes into contact with the step rising surface 17 provided on the bottom surface of the water tank housing unit 7 (FIG. 5 ( a)). However, since the step rising surface 17 is inclined, the water tank unit 6 can climb the step along the inclination (FIG. 5B), so that the water tank unit 6 can be inserted smoothly. is there. In addition, since the water tank part front end surface 12 rides on a level | step difference (FIG.5 (c)), it will be supported by the water tank accommodating part 7 bottom face, Therefore The water tank part 6 does not incline toward the front end side of an insertion direction, but is substantially horizontal. And can be inserted in a stable posture.

  When the insertion of the water tank 6 is further advanced, the water tank front end surface 12 comes into contact with the water tank housing innermost surface 18, and the mounting of the water tank 6 to the main body 1 is completed. As shown in FIG. 4, when the water tank unit 6 is mounted, the water tank unit front end surface 12 is in contact with the innermost surface 18 of the water tank housing unit and the bottom surface of the water tank housing unit 7 so that there is no gap. Since air does not leak toward the smaller gap, the air sucked into the main body 1 can be passed through the vaporization filter 8 without waste and humidified, so that the humidification efficiency can be improved. .

  When the water tank unit 6 is mounted on the main body 1, the water tank unit exterior surface 14 and the water tank unit handle 15 are in contact with the insertion port step portions 16 a and 16 b and are closed to prevent leakage of air to the outside of the main body 1. Therefore, the air sucked into the main body 1 can be passed through the vaporizing filter 8 without waste.
