Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heating device having a humidifying mechanism, and particularly to a heating device suitable for operation with a humidifying plate removed.

2. Description of the Related Art Conventionally, it is generally known that a heating device using oil, gas, or the like is provided with a humidifying mechanism including a humidifying plate and a humidifying tray inside a housing.

In order to facilitate cleaning, the humidifying plate is usually configured to be detachable from the outside of the housing.

In a conventional device having such a structure, when the humidifying plate is removed for cleaning or the like, air leaks from the hole where the humidifying plate is inserted, and effective heating cannot be expected.

One possible solution to this difficulty is to make the humidifying plate insertion hole provided in the housing as small as possible, but this method makes it difficult to attach and detach the humidifying plate and is not practical.

The present invention was devised in view of the current situation, and its purpose is to provide a heating device that does not leak air from the insertion hole of the humidifying plate.

The present invention provides a shielding plate in the housing that can swing around one end to close the humidifying plate insertion hole, and the shielding plate is urged by a spring in the direction of closing the insertion hole, so that the shielding plate can be inserted into the housing from the hole. The shielding plate is brought into pressure contact with the humidifying plate inserted into the humidifying plate, thereby preventing air leakage especially when the humidifying plate is removed.

The present invention will be described below based on an illustrated embodiment.

In FIG. 1, reference numeral 1 denotes a housing in which a combustor 2, a blower 3, etc. are built in. Air taken in from below the housing 1 is heated in the combustor, and the air is heated through a blowout grill 4 at the upper end of the housing 1. The structure is such that it is supplied into the room from the source.

A humidifying tray 5 is fixed to the inside back of the housing 1, and a humidifying plate 6 is attached to the humidifying tray 5 from the top of the housing 1.
has been inserted.

As shown in FIGS. 2 and 3, the humidifying plate 6 is formed into an L-shaped plate by a horizontal portion 6a disposed on the top surface of the housing 1 and a vertical portion 6b hanging down from the end of the horizontal portion 6a. The vertical portion 6b is shaped like a hole 7 provided in the housing 1 as shown in FIG.
It is inserted into the housing 1 from the beginning.

A shielding plate 8 is provided in the housing 1 near the hole 7, as shown in FIGS. 3 and 4, and is capable of swinging around one end to close the hole 7. As shown in FIG. 4, a spring 9 biases the hole 7 in the direction of closing it.

In the above structure, when the humidifying plate 6 is inserted into the housing 1 through the hole 7, the shielding plate 8 swings downward against the urging force of the spring 9, and the reaction force causes the vertical portion 6b to move toward the housing. Press it to the back side of 1.

As a result, the upper end of the vertical portion 6b is brought into close contact with the peripheral edge of the hole 7, and air will not leak from between the hole 7 and the vertical portion 6b.

Furthermore, since the horizontal portion 6a is in close contact with the housing 1 due to the weight of the humidifying plate 6, air will not leak from this space.

Furthermore, since the vertical portion 6b of the humidifying plate 6 is pressed by the shielding plate 8 which is biased by the spring 9, the humidifying plate 6 does not vibrate even when the blower 3 is driven, thereby preventing the generation of noise. You can also do it.

When the humidifying plate 6 is removed, the shielding plate 8 swings upward to close the hole 7, as shown in FIG.

This prevents air from leaking from the hole 7.

As explained above, according to this embodiment, it is possible to prevent air leakage from the insertion hole of the humidifying plate and improve heating efficiency not only when the humidifying plate is installed but also when the humidifying plate is removed. can.

Furthermore, since the structure is simple, it can be applied to existing devices.

Although not specifically described in the previous embodiment, a sealing material or the like may be provided at the portion of the hole 7 that contacts the shielding plate 8 to ensure airtightness.

The present invention has been described above based on preferred embodiments. According to the present invention, air leakage from the insertion hole of the humidifying plate can be prevented, and vibration of the humidifying plate can be prevented.
