Description

[Detailed explanation of the invention] <Industrial application field> This invention is mainly used for air conditioning (cooling, heating) in general households and various offices, and uses indoor air drawn from a level relatively higher than the floor surface. Existing blower-type air-conditioning/heating machines with a single circulation path system blow the cold or warm air into the room at a height that does not interfere with the suction room air after passing it through a heat exchanger to cool or heat it (this is a cooling-only machine). (including heating-only units and air-conditioning/heating switchable units), during cooling, the high-temperature indoor air that has been stagnant in the upper layer of the cold air blowing area from the blower-type air-conditioner is used, and during heating, the blower-type Actively sucks low-temperature air that has accumulated below the indoor air suction area of the air conditioner along a horizontal plane or a nearly horizontal plane, and transfers the drawn high-temperature air or low-temperature air to the blower-type air conditioner. The present invention relates to an auxiliary air blower for air conditioning configured to forcefully circulate air throughout almost the entire room, including high-temperature air in the upper layer of the room or low-temperature air in the lower layer of the room, by mixing blown cold air or warm air.

<Prior art and its problems> The auxiliary air blower having the technical content described above was developed by the present inventors and filed a patent application, etc. (a) By rationally and systematically circulating the entire indoor air, the difference in indoor temperature above and below can be minimized,
Comfortable heating and cooling can be achieved by uniformizing the temperature throughout the room, and it is particularly effective for air conditioning when there are many obstacles in the room.

(b) It is possible to avoid the occurrence of localized high or low temperature areas and the direct impact of properly cooled air or overheated warm air on the human body, thereby eliminating discomfort and adverse effects on health.

It has achieved remarkable effects.

As shown in FIG. 6, the auxiliary air blower for air conditioning according to the earlier application by the present inventors has indoor air suction ports 07 at the upper and lower ends of a large box-shaped hollow box 01. . The upper and lower suction ports 07 and 02A are selectively opened and closed during heating and heating.

However, in the case of using the prior application device with the above configuration,
Since an unnecessary upper suction port is formed in the hollow box itself during the heating operation, the box necessarily needs to be tall. Furthermore, even during cooling operation, depending on the floor height of the room to be air-conditioned, there may be no need to suck indoor air from the upper suction port, or even if high-temperature air from the upper layer is not suctioned from the upper suction port, the lower suction may be performed. By sucking indoor air through the mouth and circulating it as described above,
In some cases, sufficient comfort can be achieved by keeping high-temperature air stagnant near the ceiling above the living space and reducing the temperature difference between the top and bottom only in the living space.
In this case, the portion above the air outlet becomes a completely useless structure.

In view of these circumstances, the present invention has an object to eliminate unnecessary configuration of the entire device by making it possible to set the position of the indoor air suction port either above or below depending on the place of use and the purpose of use.

<Means for Solving the Problems> The auxiliary air blower for air conditioning according to the present invention devised to achieve the above object is provided at the lower end of the front plate and at least one side plate of a floor-standing box-shaped hollow box. an air blower main body, comprising: a suction port for indoor air, a port for blowing out the suction air into the room at the upper end of the front plate; and a fan for forced intake and exhaust inside the box; A suction port for indoor air is provided in the upper horizontal duct portion of the duct having a bent air passage along the upper part and at least one horizontal side of the hollow box, and a suction port for the suction air is provided in the lower end of the inner surface plate of the vertical duct portion. and an intake adapter provided with an outlet, and the intake adapter is fixedly connected to the blower main body so that the exhaust port is communicatively connected to the suction port, and is configured to be detachable. It is characterized by this structure.

<Operation and effects of the invention> According to the auxiliary air blower for air conditioning according to the present invention having such a characteristic configuration, it is comfortable to suck indoor air through the suction port located above the air outlet during cooling operation. When it is necessary and appropriate to create a comfortable living space, the intake adapter is fixedly connected to the main body of the blower, and in other cases, only the main body of the blower is used. Depending on the installation location and purpose of use, the indoor air suction port position during cooling can be freely set to either the upper or lower position.

Therefore, in comparison with the device of the prior application mentioned above, the present invention has made it possible to eliminate unnecessary configurations of the entire device, making it possible to use it economically and advantageously in terms of space. .

<Example> An example of the present invention will be described below in detail based on the drawings.
