Abstract

PURPOSE:To obtain appropriate temperature distribution, by a method wherein an air flow direction control device is composed so as the air is blown off from the body of a air conditioner and at the same time it is absorbed by a blower at the lower part. CONSTITUTION:Blown off air is made to diverges to the arrow mark C direction besides the arrow mark B direction by an air flow controlling damper 10 provided at a casing part of the blow off side, and descends attaching to a wall surface 11 as the bias effect, and is blown off to the arrow mark D1 direction from a blow off hole 17, at the same time is sucked by a slant stream blower which is arranged at the lower part. The temperature difference DELTAT at the upper part and lower part of a room is measured by a temperature detector 12 which is arranged at a suction grill 4 of the air conditioning device body and a temperature detector 13 which is arranged at a suction hole of a blower 3 at the lower part of the main body and the blow off air quantity is made QA:QB by an air flow direction control damper 10 after comparing and judging with the limited temperature difference T0 which was set beforehand, and furthermore by controlling the revolution number of a fan motor 18 of the slant stream blower 3 at the lower part, an air flow QC is controlled which is blow off by the slant stream blower 3, and the upper and lower temperature difference DELTAT in the room is corrected within the limited temperature difference.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an air conditioner that provides an ideal temperature distribution. 5ru1
The structure of the conventional example and its problems In the conventional air conditioner, as shown in Fig. 1a and b, the installation position of the air conditioner is high on the side wall, and it is difficult to prevent water from blowing out during cooling. , as shown in Figure a, the appropriate temperature distribution is
) However, if heating is performed using the same high side wall expansion method, even if the excess air is blown downward, the cold-head-heat-feet type temperature distribution as shown in the figure cannot be obtained. Heating methods based on the experience of radiation and conduction: Floor heating is ideal, but if you consider the combination of cooling and the limitations of living space, The problem was that

Purpose of the Invention The present invention solves the above-mentioned drawbacks and improves cooling efficiency.
．． At the time of 5- and 1'a, the air conditioner main body 4J1y is placed high on the side wall, and the most appropriate temperature distribution is set to r(1-1) at a ratio of -1:1.

In order to achieve the above-mentioned object, the air H+r6 Watsuki main body is provided with a wind direction control damper that branches the air blowing direction, The air blower is made up of an impeller placed on the lower blade of the air conditioner body and a casing that houses the impeller.
It is configured to be blown out.

DESCRIPTION OF EMBODIMENTS Hereinafter, the wind direction control device for an air conditioner according to the present invention will be described in detail based on specific embodiments shown in FIGS. 2 to 4.

In FIG. 2, reference numeral 2 denotes the main body of the air conditioner, and air is sucked in through a suction grille 4, passes through a heat exchanger 6, and then is blown into the room by a cross-flow fan 7 driven by an electric motor.

At this time, the blowing air is branched in the direction of arrow C, in addition to the conventional direction of arrow B, by the wind direction control damper 10 provided on the casing part on the blowing side, so that it descends while landing on the wall surface 11 as a bias effect. At the same time, the air is sucked in by the mixed flow blower and blown out from the air outlet 1γ in the direction of arrow D1.

In the above configuration, the upper and lower temperatures in the room can be determined by the temperature detector 12 disposed on the suction grill 4 of the air conditioner main body 2 and the temperature sensor 13 disposed at the suction port of the blower 3 below the main body. The difference ΔT is determined by 4111, and the limit temperature difference T is set in advance. After making a comparative judgment, the amount of air blown by the wind direction control damper 10 is set to QA:QB, and furthermore, by controlling the rotation speed of the fan motor 18 of the lower mixed flow blower 3, Volume of air blown out Q
c to correct the indoor temperature difference ΔT to within the limit temperature.

During heating, if the temperature difference ΔT is larger than To, then j
Diagonal downward blowing wind G%, QA by the surface control damper 10
is decreased, the vertical downward blowing air volume QB is increased, and furthermore, the fan motor 18 of the mixed flow blower 3 disposed below is
The number of revolutions of the engine is increased to increase the suction and blowout air 111. This control is then repeated.

Figures 3a and b show the additional parts installed below the main body of the air conditioner.
FIG. 7 is a plan view and a side cross-sectional view of another embodiment of the blower. FIG. 3a shows the above air outlet at the front 17a, side 17b,
c is a four-part plan view when installed in three directions, and the air sucked in from the mixed flow blower suction port is passed through the blade 16 and

3 is blown out. In this way, outside the W face plate in the lateral direction D2.
By not blowing out at 'D3, a more ideal temperature distribution74) can be achieved. As shown by arrow E in the embodiment of FIG. 2, the effect of radiation due to the wall surface 11 being heated by the warm air blown vertically downward from the main body of the air conditioner also helps to enhance the effects of the present invention. are doing,.

Effects of the Invention As described above, according to the present invention, the air blown from the main body of an air conditioner is branched downward and vertically downward at an appropriate ratio, in contrast to the conventional method, and is further blown vertically downward. This air is placed below the main body of the air conditioner, and the rotational speed of the blower on this side is appropriately controlled, and the air is sucked in and blown out at the same time. Not only during heating, but also during heating, it provides an ideal temperature distribution while maintaining the conventional side wall height Iga supplement system.

Furthermore, as an additional effect, the warm air blown out directly below the air conditioner from the main body of the air conditioner heats the wall surface, thereby providing heating by radiant heat from the wall surface, which promotes the effects of the present invention.

FIG. 2 is an explanatory diagram of a blowout flow from the essential equipment of an air conditioner according to an embodiment of the present invention.
