Abstract

PROBLEM TO BE SOLVED: To solve a problem that since cold and hot air can not spread to every indoor corner by only the air supply device (a fan) of a hot air heater and a room air-conditioner, unevenness in temperature occurs and to prevent the occurrence of the unevenness, spreading of air of the sir supply device and an air supply speed is increased but coldness in a winter season and hotness in a summer season in a place shielded by a furniture and can not be improved. SOLUTION: Cold and hot air in a place where the air can not reach by only the air supply device (a fan) with which a cooling and heating device is provided are sucked and discharged through a suction exhaust flexible duct situated in the place. By mixing and agitating air in a place where a cold and hot air amount is high, unevenness in temperature is prevented from occurring. Even in a place where hot and cold air does not reach only by the cooling and heating device, unevenness in temperature is prevented from occurring by generating a flow through which hot and cold air is spread.

Description of the Related Art Conventional room air conditioners and warm air heaters, which are widely used in ordinary households, are placed in a corner of a room, and a fan provided in the room sucks air in the room and sends it out as cool and warm air. ， The room was air-conditioned.
For example, in heating such as a hot air heater, a fan discharges warm air near the floor at high speed and spreads it far, and the warm air rises upward to warm the entire room. , The warm air does not spread far,
They tended to rise relatively quickly, accumulating warm air in the ceiling and tending to heat their heads. In contrast, the lower part of the corner of the room, which was blocked by furniture and did not reach the warm air, was not heated at all, and tended to cool in inverse proportion to the heating of the ceiling. In order to solve this problem, air is agitated with a fan or the like, but it is not possible to stir the air in places where cold air has accumulated. There was an evil to feel. In the case of cooling, cooling air is discharged in a horizontal direction along the ceiling from the room air-conditioner attached to the ceiling in the opposite direction of heating, and the cooling air is dropped from top to bottom to cool widely. The place where the flow of cold air flows was cooled down well, and in other places, especially at the positions on both sides of the cold air blowout, there was a problem that uneven cooling could occur, which means that the air did not cool down. When heating with a room air-conditioner, warm air is blown downwards. However, this blowing capacity does not provide sufficient warming even near the floor directly below. Compared to, the temperature unevenness tended to expand further. In addition, when there is uneven temperature, not only comfort in the room is lost, but also cooling and heating are performed on the basis of a place with bad conditions, so that cooling and heating energy is wasted.

For example, the warm air discharged from the warm air heater for heating starts rising immediately, and an air flow is generated such that the warm air accumulates on the ceiling.
On the other hand, in the corner of the room where the warm air from the fan does not reach, the cool air stays and cools down more and more, resulting in large temperature unevenness. It is impossible for a fan of a hot-air heater to send warm air to every corner of the room, and it cools down, especially in places blocked by furniture, because the warm air does not reach at all. According to the present invention, the air in the cooled portion is sucked from an intake port of a flexible duct disposed therein or an intake port provided in a wall, and discharged to a ceiling or the like where warm air is accumulated, and mixed with the warm air accumulated in the ceiling and stirred. And eliminates uneven temperature in the ceiling. In addition, by sucking air from a cold place, warm air is flown even in places where warm air has not reached before, thereby eliminating cold near the floor. In particular, the air inlet is placed under a desk in one corner, and the cold air there is sucked and discharged, and warm air is introduced and heated. In this way, the cold air accumulated locally is sucked and mixed and stirred with the warm air at the ceiling, thereby eliminating temperature unevenness in the entire room. The concept is exactly the same for cooling. It sucks and discharges the warm air accumulated in one corner of the room, creates a flow so that cool air comes into it, and discharges the warm air to the cool air mainstream of the room air-con, mixing and stirring to eliminate uneven temperature. It should be noted that the air circulation method can be either of two methods for cooling and heating. In other words, taking the case of heating as an example, one is a method in which local cool air is sucked, discharged to the ceiling, and stirred with warm air. In the other method, on the other hand, a part of the warm air accumulated on the ceiling or the like or the warm air at the outlet of the warm air heater is sucked by the present apparatus, and discharged and mixed into a locally cold part. The same is true for cooling. Also, using a plurality of devices of the present invention,
Ideally, the air circulation should be combined in various ways to minimize temperature unevenness. In addition, since the air on the floor is inevitably dusty due to human walking, etc., to prevent these from diffusing into the room,
An air purifier will be installed to keep the air clean.

This diagram illustrates the case of heating. Warm air from the hot air heater 1 is discharged along the floor 2. Although the flow of the warm air is conceptually indicated by the dashed arrow 3, the warm air gradually rises toward the ceiling 4, is cooled, and returns to the heating device 1. Eventually, a warm air circulation flow as indicated by the broken arrow 3 is obtained. For this reason,
Cool air accumulates in the corner of the room on the other side without heating. Here, an intake flexible duct 5 is arranged, cool air is sucked as shown by an arrow 6, and an electric air blower 7 having a built-in air purifier and a cool air near the ceiling 4 as shown by an arrow 9 through an exhaust flexible duct 8. And mix with warm air accumulated on the ceiling. A plurality of intake / exhaust ducts 5 and 8 can be installed for one electric blower 7, and open / close dampers 10 are provided for each, and the dampers are opened and closed according to the arrangement of furniture, or the opening degree is adjusted. ， Minimize temperature unevenness.
FIG. 2 is an embodiment showing a case of cooling. The basic configuration is the same as in FIG. In this case, cool air is blown from the cool air outlet of the room air-con 11 through the intake flexible duct 5, and the cool air is discharged and mixed to a place where the cool air does not reach via the electric blower 7 and the exhaust flexible duct 8. It is a case where it is canceled. FIG. 3 shows a case where the intake and exhaust ducts 5 and 8 and the blower 7 are fixed and buried in a wall or behind a ceiling. The basic operation is the same as in FIGS. 1 and 2, but in this case, as shown in the plan view of FIG. 4, the intake and exhaust ports may be blocked by furniture or the like. The intake / exhaust port closes the opening / closing damper 10 and, for example, at a place to be cooled such as under the desk 12, the extension flexible duct 13 is drawn under the desk to eliminate the cooling.
