Abstract

PURPOSE:To provide an efficient humidifying operation and enable a ventilation of a short period of time by a method wherein an upper pan for accumulating water, a lower pan for movably mounting the upper pan and a valve member for opening or closing a hole are installed near the air-blowing port. CONSTITUTION:When an upper pan 8 is slid toward an arrow A, a ventilation hole 6a appears at the left side of the upper pan 8, a surrounding atmosphere and the interior are communicated to each other through the hole and the blowing air of the air conditioner is discharged out, so that a ventilation can be carried out in a short period of time. A valve member of convex form 8c for opening or closing the hole 6a is integrally formed with the upper pan 8. The interior of the water 9 accumulated in the upper surface of the upper pan has a larger area abutting against air indicated by an arrow (d) through a substantial mountain-shaped humidity absorption material 9a in order to promote an evaporation of the water. In case of heating through the air conditioner, a part of the hot air heated by a heat exchanger is evaporated and humidified at the water surface of the upper pan 8 and the surface of the humidity absorption material 9a, is passed through a clearance 8b between the upper pan 8 and the lower pan 9 and then blown into the interior of the room together with the air indicated by an arrow (c).

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an air conditioner, and more particularly to a wall-mounted air conditioner capable of heating.

[Background of the invention]

A conventional air conditioner was as described in Japanese Utility Model Application No. 59-146210. This will be explained with reference to FIG.

11 is a casing, 12 is a front panel, 16 is a suction grill, 24 is a heat exchanger, 16 is a drain pan that stores water 17, and supplies water 17 to a humidifying section 28. Air is sucked in from the suction grille 13 by the blower 20 as shown by an arrow 21, humidified by the humidifier 28, and blown out from the blowout louver. However, in this case, the heat exchanger 240 has little ventilation and no consideration was given to the effective utilization of the heat exchanger 24 itself. Also, ventilation was not considered.

[Purpose of the invention]

The purpose of the present invention is to evaporate water using the air of an air conditioner,
It is intended to humidify air conditioning and heating systems and to improve ventilation.

[Summary of the invention]

Near the air outlet, there is an upper tray that stores water, a lower tray on which the upper tray is movably placed, a hole that communicates with the outside provided in a member located behind the upper tray, and a hole that communicates with the outdoors. It is equipped with an opening/closing member that opens and closes the hole, and uses warm air to raise the water level in the upper tray, thereby providing efficient humidification and ventilation in a short time.

(Embodiment of the Invention) An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

1 is a casing, and between it and a decorative cover 2, a heat exchanger 3, a blower 4, electrical control parts, etc. are arranged and mounted.

Reference numeral 2a designates a suction port integrally formed in the decorative cover 2, and 2b designates a blowout port. Arrows B and C in FIG. 2 indicate the flow of air during heating operation.

Reference numeral 5 denotes an installation plate for installing the casing 1 on the wall 6. Further, 6a is a hole opened in the wall 6 and communicates with the outside.

Reference numeral 7 denotes a lower plate which has a hole in a part of its back side, and this hole matches the hole 6a of the wall 6, and the vaginal wall 6alC has a cylinder 10 and an elbow 10a can be attached to the outside of the cylinder 10. ing. Note that the member provided with the hole is not limited to the lower plate 7, and may be provided in another member. For example, if the installation plate 5 is large enough to extend to the rear of the upper plate, the installation plate 5
A hole may be formed in the hole. In other words, it is only necessary to form a hole for ventilation.

Further, on the upper surface of the lower plate 7, an upper plate 8 having a convex portion 8a below is mounted so as to be slidable from side to side. Further, the lower plate 7 and the upper plate 8 form a ventilation path with a gap 8b on the back, bottom and front surfaces. When the upper plate 8 is slid in the direction of the arrow as shown in FIGS. 1 and 3, a ventilation hole 6a appears on the left side of the upper plate 8, and the hole allows communication between the outside air and the room. In addition, the hole 6a
The opening/closing member may be a member other than the upper plate.

Since this hole 6a opens at the rear of the humidifying upper tray, no special ventilation space is required. Furthermore, since the air from the air conditioner is discharged, ventilation can be achieved in a short time. 8C is a convex opening/closing member for opening and closing the hole, and is integrally formed with the upper plate 8. In this way, since the opening/closing member for opening and closing the hole is integrally formed with the upper plate, the hole can be opened and closed by moving the upper plate. Note that there is no need to form the opening/closing member integrally with the upper plate. In other words, it is sufficient if the holes can be opened and closed to allow ventilation.

・ 6 ・ 9 is water stored on the upper surface of the upper plate, and in order to promote water evaporation, a roughly mountain-shaped moisture absorbing material 9 a is used to increase the area that comes into contact with the wind as indicated by arrow d. . Because of this, when the air conditioner is heating, a part of the hot air warmed by the heat exchanger is evaporated and humidified on the water surface of the upper plate 8 and the surface of the moisture absorbing material 9a, as shown by arrow d, and then It passes through the gap 8b between the plates 90 and is blown into the room along with the arrow C.

Since the upper plate 8 is surrounded by hot air (signal d), the water temperature rises quickly and evaporates easily.

Note that if humidification is performed using this method, heating and cooling can be performed without affecting the wind passing through the heat exchanger 3, so that heat exchange can be performed efficiently.

〔Effect of the invention〕

According to the present invention, humidification can be performed without affecting the ventilation of the heat exchanger. Further, it is possible to provide a ventilation device that does not require a special space for ventilation and can perform ventilation in a short time.
