Abstract

PURPOSE:To prevent leakage of water out of a box by positioning a receiving surface of a mounting base which receives a humidifying element lower than a takeout port of a box and forming a rising part which rises on the humidifying element side around the receiving surface, so that all leaking water can be received by a drain pan without allowing water to leak out of the box. CONSTITUTION:A humidifier 7 is so constituted that a humidifying element 9 can be detached from a takeout port 11 provided on one side of a box 3. A mounting base 8 is formed in a flat-bottomed tray having a rising part 13 which is bent around a receiving surface 12 which receives the humidifying element 9, and the receiving surface 12 is mounted at a lower position than the takeout port 11 of the box 3. In thus constituted humidifier, as the receiving surface 12 of the mounting base 8 for receiving the humidifying element 9 is located lower than the takeout port 11 of the box 3 and further the rising part 13 is formed on the humidifying element 9 side around the receiving surface 12, water leaking from the humidifying element 9 and the like, not reaching the takeout port 11, can be entirely received by a drain pan without leaking out of the box 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a humidifier that is incorporated into an air conditioner or the like and humidifies an air flow.

[Prior Art] When heating in winter, the indoor atmosphere tends to become dry and it is necessary to actively humidify the room. For this reason, for example, air conditioners and ventilators equipped with a humidifying function have been developed. That is, the structure is such that a humidifying device for humidifying the air supply flow is incorporated in the air supply flow path of an air conditioning ventilation system as shown in Japanese Utility Model Application Laid-open No. 63181743. The humidifying device includes a humidifying element, a water supply device for supplying water to the humidifying element, and a drain pan, for example, in a box body.
It has a configuration as shown in Publication No.-148539,
An outlet for the humidifying element is formed in the box, from which maintenance and inspection of the humidifying device can be carried out.

The humidifier humidifies the airflow by means of a humidifying element.

Excess water generated in the humidifying element is received in a drain pan and drained as appropriate.

[Problems to be Solved by the Invention] In the conventional humidifying device described above, in order to make it easy to attach and detach the humidifying element, the receiving surface of the mount that receives the humidifying element is the same as the outlet made in the box body. Due to the height of the humidifying element, some of the water leaking from the humidifying element may leak out of the outer box, which is an issue that needs to be resolved.

This invention was made to solve the conventional problem, and aims to provide a humidifying device that can prevent water from leaking out of the box.

[Means for Solving the Problems] A humidifying device according to the present invention is provided with a receiving surface for receiving the humidifying element of a mounting base for mounting the humidifying element at a lower level than the outlet of the box body, and a humidifying element is provided around the receiving surface. A rising part is formed on the side, and the drain pan is disposed below this mounting base.

[Function] In this invention, the receiving surface of the mount that receives the humidifying element is located at a lower level than the outlet of the box, and a rising part is formed around the receiving surface that rises toward the humidifying element. Water leaking from the element will not reach the outlet located at a higher level, and all water will be received in the drain pan without leaking out of the box.

[Example] Fig. 1 shows an air conditioning ventilation system as an application example of the present invention, and Fig. 2 is a sectional view showing the configuration of the main parts thereof. The air-conditioning ventilation system on the ward side defines an air supply passage and an exhaust passage in a box body 3, which has an inlet 1 and an outlet 2, one set on the indoor side and one on the outdoor side, and a heat exchange element. 4 and air supply and exhaust air blowers 5.6.

A humidifying device 7 is installed in an air supply path from the blowing side of the air blower 5 to the indoor air outlet 2. The humidifying device 7 consists of a humidifying element 9 mounted on a mounting base 8, a water supply device for supplying water to the humidifying element 9, and a drain pan 10. It is configured to be removable.

The mounting base 8 is formed into a flat-bottom dish shape with a raised portion 13 bent around a receiving surface 12 that receives the humidifying element 9, and the receiving surface 12 is positioned below the outlet 11 of the box body 3. is installed on.

The water supply device includes a water supply tank 14, an electromagnetic valve 15 that controls the amount of water supplied to the tank, and piping that supplies water from the water tank 14 to the humidifying element 9. The water supply device is provided above the mount 8, and a drain pan 10 is provided below the mount 8 to receive water leakage from each connection portion of the water tank 14, the humidifying element 9, and the like. A humidifier inspection lid 16 is removably attached to the outlet 11.

The above-mentioned air conditioning and ventilation system can exhaust indoor air and take in outdoor air through the heat exchange element 4, thereby providing heat exchange ventilation and, if necessary, humidifying the supplied air flow to supply outdoor air indoors.

Water leakage from the humidifying element 9 etc. in the humidifying device 7 is caused by the fact that the receiving surface 12 of the mounting base 8 that receives the humidifying element 9 is located at a lower level than the outlet 11 of the box body 3, and the humidifying element 9 is located around the receiving surface 12. Since the rising portion 13 rising to the side is formed, the drain pan 10 does not reach the outlet 11 and all of the liquid is received in the drain pan 10 without leaking out of the box body 3.

[Effects of the Invention] As is clear from the above description of the embodiments, according to the present invention, the receiving surface of the mount that receives the humidifying element is located at a lower level than the outlet of the box, and furthermore, there is no space around the receiving surface. A rising part is formed on the side of the humidifying element, so
Water leaking from the humidifying element does not reach the outlet located higher than the humidifying element, and all of the water is received in the drain pan without leaking out of the box, thereby preventing water from leaking out of the box.
