JPH11257727A - Wall hang room air conditioner capable of mounting and removal of extension duct fitted with floor side outlet port - Google Patents

Abstract

PROBLEM TO BE SOLVED: To enable comfortable heating by arranging the constitution such that hot wind goes up gradually to the top from the bottom inside a room near a floor face thereby forming the room temperature environment of head being cold and feed being hot such as that the temperature goes down a little more the higher position within the room closer to a ceiling it is in, with the floor side warm. SOLUTION: Only at heating, an extension duct 3 fitted with an outlet port close to user's feet is mounted on the extension duct on/off part 2 provided at the outlet part of the main body 1 of a wall hanging type of room air conditioner indoor machine and the direction of blowout is switched, and hot wind is blown not to the usual outlet port but to the extension duct 3 to blow out it from the floor side outlet port 4 arranged in the vicinity of the floor face, thus the room temperature environment of head being cold and feet being hot such as that the vicinity of the floor face is warmest and that the temperature drops more the closer it comes to the upper part inside the room is formed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall-mounted room air conditioner capable of blowing out hot air from near the floor surface when heating with a wall-mounted room air conditioner and having a detachable extension duct with a foot outlet. Things.

[0002]

2. Description of the Related Art A conventional wall-mounted room air conditioner indoor unit is:
Usually, it is a device installed at the upper part of the indoor wall for effective cooling, and the outlet is located at the lower part of the air conditioner body.

[0003]

In this conventional wall-mounted room air conditioner, an effective cooling operation of the whole room can be performed effectively in combination with the characteristic that the cool air naturally descends during cooling, but it is possible to perform a hot air cooling operation during heating. Due to its natural tendency to rise naturally, there is a drawback that even when hot air blows down from a high position near the ceiling, the portion close to the floor is not sufficiently heated, and only the upper part of the room is warmed and the feet are easily cooled. As a result, it is not possible to create an ideal heating condition for the human body, and the opposite is true.In other words, an environment in which the temperature near the ceiling above the room is high and the temperature near the floor is low is created. Had been impaired. In addition, since the area near the ceiling, which is unnecessary space from the viewpoint of warming the human body, is warmed more, it is against energy conservation. The present invention has been made to eliminate these disadvantages.

[0004]

Means for Solving the Problems A structure in which a blowing direction of a wall-mounted room air-conditioner indoor unit main body (1) can be switched in a blowing direction, and hot air blows to an extension duct attaching / detaching portion (2) only during heating. An extension duct (3) having a foot outlet (4) at its end is attached to the extension duct attaching / detaching portion (2). The present invention is a wall-mounted room air conditioner having a detachable extension duct with a foot outlet configured as described above.

[0005]

Embodiments of the present invention will be described below. During cooling, only the wall-mounted room air conditioner indoor unit (1) is operated as usual, and during heating, an extension duct (3) is attached to the extension duct attachment / detachment part (2), and all or part of the hot air is blown. Is switched from the normal air outlet of the air conditioner to the extension duct (3), and warm air is blown out from the foot outlet (4) via the extension duct. At this time, if necessary, consider the pressure loss of the duct so that air can be blown effectively, and select a fan that can increase the static pressure of the blower fan of the main unit, or install an intermediate booster fan in the duct part It is effective if installed. further,
A humidifier may be incorporated in front of the foot outlet (4) in order to prevent the heating by the air conditioner from usually causing a decrease in humidity and creating an excessively dry indoor environment. Also,
In order to diffuse hot air widely on the floor, the shape of the foot outlet (4) was changed from the normal outlet, and a perforated mat with air-blowing tubes with air vents incorporated in the mat for floor bedding The foot outlet (5) may be used. Further, a duct mounting portion (6), which can be mounted to cover the air outlet by bonding, adhesion, fixing with bolts, or the like, is attached to the air outlet of a normal wall-mounted room air conditioner indoor unit, and the duct mounting portion (6) May be connected to the extension duct (3) and the foot outlet (4). In this case as well, the installation of the intermediate booster fan in the extension duct section and the incorporation of a humidifier in front of the foot outlet (4) are also effective, as described above.

[0006]

With such a configuration, warm air can be blown out from the vicinity of the feet and the floor, and the warm air gradually rises from the lower part of the room near the floor to the upper part, so that the feet become warmer. In this case, a room temperature environment of head-and-foot heat is formed in which the temperature is slightly lowered as the position is higher in the room near the ceiling, thereby enabling comfortable heating. In addition, since the heating is performed mainly around the floor near the human body, the rate of heating around the unnecessary ceiling is reduced, which also contributes to energy saving.
