  In such a humidifying device, when a gap is formed between the inner wall of the water tank housing portion that houses the water tank portion in the humidifying device main body and the water tank portion in a state where the water tank portion is mounted, the air passage passes through the vaporization filter. However, air tends to flow toward the gap where the pressure loss is small. As a result, air leaks out of the air flow path through this gap, so that air is discharged into the room without passing through the vaporization filter, resulting in a decrease in humidification efficiency.

  For this reason, when designing the humidifier, the arrangement of parts is adjusted so that there is no gap between the front end surface of the water tank and the water tank housing, but resin molded products are used for many parts of the humidifier. Therefore, a draft angle for releasing from the mold is provided on the surface of the part, and this draft creates a gap between the parts.

  Further, the resin molded product has a problem of warping during molding. Since the aforementioned draft angle is provided on the tip surface of the water tank part, even if the shape of the water tank contact surface with which the tip surface of the water tank part abuts is provided along this draft angle in the water tank housing part, When the surface is warped, a gap may be generated due to the warp. For example, as shown in FIG. 8, when the water tank part 31 is mounted, when the water tank contact surface 32 is displaced to the insertion port side of the water tank part 31 due to warping, the water tank contact surface 32 is the front surface of the water tank part. 33 will be pushed out to the insertion port side, and since the insertion port of the water tank part 31 will not be closed, a clearance gap will arise. On the contrary, as shown in FIG. 9, when the position of the water tank contact surface 32 is shifted to the exterior side due to warping, the distance between the water tank front end surface 33 and the water tank contact surface 32 that should be contacted by design is Since it opens and does not contact, a gap is created.

  The present invention is for solving the above-mentioned problems, and prevents the formation of a gap by suppressing the warpage of the water tank contact surface, allowing the air sucked into the main body to pass through the vaporization filter without waste, and high humidification efficiency. An object of the present invention is to provide a humidifier that can be used.

  The present invention provides a main body frame that forms a main body exterior, a water tank portion that is detachably mounted through an insertion port provided in the main body, and that stores a certain amount of water, and a ventilation path that communicates the suction port and the outlet. A blower case that is attached to the blower case and blows air to the blower path, a vaporization filter that is installed in the blower path in a state where the lower part is immersed in the water of the water tank unit, and the insertion port In a humidifying device comprising a water tank housing part for housing the water tank part, a water tank contact surface that does not produce a gap with the water tank part front end surface in a state where the water tank part is mounted is provided in the innermost part of the water tank housing part. At the same time, the water tank contact surface is positioned by being sandwiched between the main body frame and the blower case.

  The humidifier according to claim 1, wherein the water tank contact surface is locked only by a fitting structure provided in the main body frame and the blower case.

  The humidifier according to claim 2, wherein the water tank contact surface is formed integrally with the air blowing case.

  By adopting the above-described configuration, it is possible to prevent a gap between the water tank contact surface and the front end surface of the water tank portion by suppressing warpage of the water tank contact surface, and to vaporize the air sucked into the main body without waste. Since it passes through a filter, high humidification efficiency can be exhibited.

  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 humidifier of the present invention provides a water tank contact surface that does not create a gap with the water tank front end surface, and positions the water tank contact surface with a main body frame and a blower case that sandwich the water tank contact surface. That is, a water tank contact surface is provided so as to close a gap other than a ventilation path that allows air to pass through the vaporization filter in a state where the water tank portion is mounted, and this water tank contact surface can be disposed at an appropriate position. It was regulated.

  Since the water tank abutment surface is sandwiched from the inside and outside by the main body frame and the air blowing case, the water tank abutment surface is placed at an appropriate position so that no gap is generated in the air flow path. Since air is passed through the vaporizing filter without waste, high humidification efficiency can be obtained.

  Also, by locking the water tank abutment surface only with the fitting structure provided on the main body frame and the air blowing case, no locking parts such as screws are required, and bosses and holes for screwing are molded into the parts. Since it is not necessary, the cost can be reduced.

  In addition, since the water tank contact surface is formed integrally with the air blowing case, there is no joint portion with the air blowing case, so that the risk of generating a gap between components can be reduced.

  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 1a that forms the front and side front portions of the main body 1 that is a resin-molded product, and a main body rear frame 1b that forms side rear portions and a back surface. There are provided a blower outlet 2 for discharging humidified air in the room 1, an operation part 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. Yes.

  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 part 6 which is a resin molded product is detachably attached to the water tank housing part 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. Furthermore, the upper end of the water tank part exterior surface 12 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. In addition, the draft surface for releasing from a metal mold | die is provided in the front end surface 13 of the water tank part 6. FIG.

  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 13 and the partition plate 9. Further, a holding piece 14 for restricting the movement of the vaporizing filter 8 is provided on the water tank portion front end face 13 and the partition plate 9. When the vaporizing filter 8 is installed, the holding piece 14 is used as a mark. Insert inside from above.

  FIG. 3 is a vertical cross-sectional configuration diagram of the humidifier when the water tank unit 6 is mounted. An insertion port step 15 is bent at the upper side of the opening of the insertion port 5 so as to slightly enter the water tank housing portion 7 from the side surface of the main body 1, and when the water tank portion 6 is attached to the main body 1, The upper end of the surface 12 abuts on the insertion port step portion 15 to close the insertion port 5.

  A blower case 17 communicating with the blower outlet 2 is attached around a blower 16 constituted by a fan 16a and a motor (not shown), and the blower case outer wall surface 18 and the partition plate 9 of the water tank unit 6 are substantially flush with each other. Is formed. By this substantially identical surface, the inside of the main body 1 is divided into two spaces, a blower path space 19 in which the blower 16 is disposed and a water supply tank storage space 20 in which a water supply tank (not shown) is stored. 1 A blower passage through which air passes in the order of a suction port (not shown) provided on the back surface, a vaporization filter 8, a blower 16, and a blower outlet 2 is formed via a blower case 17.

  FIG. 4 is an exploded perspective view of the blower case 17. The blower case 17, which is a resin molded product, includes a motor cover 21 to which the blower 16 is attached and a fan cover 22 that surrounds the fan 16 a. In addition, about the structure of the ventilation case 17, it does not necessarily depend on 2 components like a present Example. Moreover, the water tank contact surface 23 which is arrange | positioned in the lower part of the fan cover 22 in the innermost part of the water tank accommodating part 7 in the state which assembled the humidifier, and the water tank part front end surface 13 contact | abuts when the water tank part 6 is mounted | worn. Is provided integrally with the fan cover 22.

  An outer wall stepped portion 24 is formed to bend into the lower side of the blower case outer wall surface 18 so as to enter the inner side of the water tank housing portion 7, and the upper end of the partition plate 9 abuts as shown in FIG. 3. This contact state completes the mounting of the water tank 6 to the main body 1 and closes the air passage space 19.

  In the state in which the water tank unit 6 is mounted, the water tank front end surface 13 is in contact with the water tank contact surface 23 arranged at the innermost part of the water tank housing unit 7. Since the shape of the water tank contact surface 23 is molded along the draft provided on the water tank front end surface 13, there is a gap between the water tank contact surface 23 and the water tank front end surface 13 when the water tank 6 is attached. Does not occur. Thereby, air can be allowed to pass through the vaporizing filter 8 without causing air leakage from the air blowing path. A reinforcing rib (not shown) is provided on the exterior surface of the water tank abutting surface 23 to increase the rigidity of the water tank abutting surface 23 to suppress deformation such as warpage.

  Further, as shown in FIG. 5, the water tank abutting surface 23 is in contact with a rib receiver 25 provided on the main body rear frame 1 b of the main body 1 from the insertion port 5 side, as shown in FIG. 5. On the other hand, a positioning surface 26 provided on the motor cover 21 of the blower case 17 is in contact with the exterior side. With this structure, even if the water tank abutment surface 23 is warped, the water tank abutment 23 can be prevented from being warped by being sandwiched from the inside and outside of the water tank abutment surface 23 by the main body rear frame 1b and the motor cover 21. Since the contact surface 23 is disposed at an appropriate position and no gap is generated in the air blowing path without fail, the air sucked into the main body 1 is passed through the vaporization filter 8 without waste, so that high humidification efficiency can be obtained. . Hereinafter, detailed shapes of the water tank contact surface 23, the main body rear frame 1b, and the motor cover 21 will be described with reference to FIGS.

  FIG. 6 is a diagram illustrating the configuration of the water tank contact surface 23 and the main body rear frame 1b of the main body 1. A positioning rib 27 is provided at the lower part of the water tank abutting surface 23. On the other hand, a rib receiver 25 and a slit portion 28 adjacent to the rib receiver 25 are provided at positions facing the positioning rib 27 of the main body rear frame 1b. Is provided. In the assembled state of the humidifying device, the positioning rib 27 comes into contact with the rib receiver 25 while being inserted into the slit portion 28. If the water tank abutment surface 23 is warped to the insertion port 5 side, the water tank abutment surface 23 tries to swell from the original design position to the insertion port 5 side. By suppressing the bulging of the positioning rib 27 from the insertion port 5 side, the displacement of the water tank contact surface 23 toward the insertion port 5 side is restricted. Thereby, since the water tank contact surface 23 does not push out the water tank part front end surface 13, the partition plate 9 of the water tank part 6 and the outer wall surface level | step-difference part 24 can contact | abut reliably, and the ventilation path space 19 can be obstruct | occluded. There is no air leakage from the path.

  FIG. 7 is a diagram illustrating the configuration of the water tank contact surface 23 and the motor cover 21 of the blower case 17. The motor cover 21 is provided with a positioning surface 26 that contacts the surface of the water tank contact surface 23 on the exterior side, and the positioning surface 26 overlaps from the exterior side of the water tank contact surface 23 in the assembled state of the humidifier. If the water tank abutment surface 23 is warped to the exterior side, the water tank abutment surface 23 tends to swell from the original design position to the exterior side, but the positioning surface 26 is a water tank abutment. By suppressing the swelling of the surface 23 from the exterior side, the positional deviation of the water tank contact surface 23 to the exterior side is regulated. Thereby, since the water tank part front end surface 13 and the water tank contact surface 23 come into contact with each other reliably, no gap is generated, and no air leakage from the air blowing path occurs.

  That is, the movement of the water tank contact surface 23 is restricted by being inserted into and fitted into a fitting structure formed by a combination of the rib receiver 25 of the main body rear frame 1b and the positioning surface 26 of the motor cover 21. . Since the water tank contact surface 23 is locked only by the fitting structure between the three parts, there is no need for a locking part such as a screw, and a screw-fixing boss or hole is formed in the water tank contact surface 23 or Since it is not necessary to provide in the main body rear frame 1b, the motor cover 21, etc., cost can be held down. The fitting structure is not limited to the structure of the present embodiment, and may have a fitting structure in which the water tank contact surface 23 is engaged with each of the main body rear frame 1b and the motor cover 21.

  Moreover, since one side of the water tank abutment surface 23 is fixed to the motor cover 21 by integrally molding the water tank abutment surface 23 with the motor cover 21 serving as the blower case 17, the engagement is made only by the fitting structure. In addition, the movement of the water tank contact surface 23 can be reliably controlled. Furthermore, since there is no joining location of the water tank contact surface 23 and the motor cover 21, the risk of generating a gap between components can be reduced.
