Description

TECHNICAL FIELD The present invention relates to a humidifying device incorporated in an air conditioner or the like to humidify an air flow.

[Prior Art] During heating in winter, the interior of a room is likely to be in a dry atmosphere, and it is necessary to actively measure humidification. Therefore, for example, an air-conditioning ventilator having a humidifying function has been developed.
That is, the humidifying device for humidifying the air supply is incorporated into the air supply passage of the air-conditioning ventilation device as shown in Japanese Utility Model Laid-Open No. Sho 63-181743. The humidifying device includes a humidifying element, a water supplying device for supplying water to the humidifying element, and a drain pan, which are incorporated in a box body, for example, an actual Kaihei 1-
With the structure as shown in Japanese Patent No. 148539, the outlet of the humidifying element is formed in the box, and maintenance and inspection of the humidifier can be performed from here.

The humidifying device humidifies the air flow by the humidifying element.
Excess water generated in the humidifying element is received by the drain pan and appropriately drained.

[Problems to be Solved by the Invention] In the above-described conventional humidifying device, in order to facilitate the attachment and detachment of the humidifying element, the receiving surface of the mounting base that receives the humidifying element is the same as the outlet that is opened in the box. Since the height is increased, there is a problem to be solved that a part of water leaking from the humidifying element may leak out of the outer box.

The present invention has been made in order to solve the conventional problems, and an object thereof is to obtain a humidifying device capable of preventing water leakage to the outside of the box body.

[Means for Solving the Problems] In a humidifying device according to the present invention, a receiving surface for receiving a humidifying element of a mount for mounting the humidifying element is provided at a position lower than an outlet of the box, and the humidifying element is provided around the receiving surface. A rising part that rises up to the side is formed, and the drain pan is arranged below the mounting base.

[Operation] In the present invention, since the receiving surface of the mounting base for receiving the humidifying element is located lower than the outlet of the box, and the rising portion rising to the humidifying element side is formed around the receiving surface, the humidifying element is formed. The leakage of water from the element does not reach the outlet located at a higher position than that, and the whole is received by the drain pan without leaking out of the box.

[Embodiment] FIG. 1 shows an air-conditioning ventilation device as an application example of the present invention, and FIG. 2 is a sectional view showing a configuration of a main part thereof. The air-conditioning ventilator of the illustrated example has a box body 3 in which a suction port 1 and a blow-out port 2 are provided inside and outside, respectively.
The air supply passage and the exhaust passage are defined, and the heat exchange element 4 and the blowers 5 and 6 for air supply and exhaust are incorporated. A humidifying device 7 is incorporated in the air supply passage extending from the outlet side of the blower 5 for air supply to the outlet 2 on the indoor side. Humidifier 7
Is composed of a humidifying element 9 mounted on the mount 8, a water supply device for supplying water to the humidifying element 9, and a drain pan 10. The humidifying element 9 can be attached and detached from an outlet 11 provided on one side of the box body 3. Is configured. The mounting base 8 is formed in a flat-bottomed dish shape in which a rising portion 13 is bent around a receiving surface 12 that receives the humidifying element 9, and the receiving surface 12 is lower than the outlet 11 of the box 3. Is attached to. The water supply device comprises a water supply tank 14, a solenoid valve 15 for controlling the amount of water supplied to the water supply tank 14, piping for supplying water from the water supply tank 14 to the humidification element 9, and the like. The water supply device is provided above the mounting base 8, and under the mounting base 8, a drain pan 10 that receives water leakage from each connection portion of the water supply tank 14, the humidification element 9, and the like is disposed. A humidifier inspection lid 16 is detachably attached to the outlet 11.

The air-conditioning ventilator can heat the heat exchange ventilation by exhausting the indoor air and the outdoor air through the heat exchange element 4, and humidify the supply air stream as necessary to supply the outdoor air to the room. Water leakage from the humidifying element 9 and the like in the humidifying device 7 is such that the receiving surface 12 of the mounting base 8 for receiving the humidifying element 9 is lower than the outlet 11 of the box body 3, and the humidifying element 9 surrounds the receiving surface 12. Since the rising portion 13 that rises to the side is formed, it does not reach the outlet 11 and does not leak to the outside of the box body 3, and the whole drain pan 10 is provided.
Will be accepted by.

[Effects of the Invention] As is apparent from the description of the embodiments above, according to the present invention, the receiving surface of the mounting base for receiving the humidifying element is lower than the outlet of the box body, and the surroundings of the receiving surface are Since the rising part that rises on the humidifying element side is formed,
The leak of water from the humidifying element does not reach the outlet located at a higher position than that, and the leak is not leaked to the outside of the box body, but all is received by the drain pan, and the leak of water to the outside of the box body can be prevented.
