Abstract

PURPOSE:To prevent air from directly blowing to the body of a sleeping person by providing an opening and closing damper which shuts off the air from an air conditioner at its lower discharge opening when it is operated while a person is asleep. CONSTITUTION:The main body 1 of an air conditioner is provided with an intake opening 2, upper discharge opening 3, and lower discharge opening 4, and the wind circuit in the main body 1 of the air conditioner consists of an air guide 5, upper cross-flow fan 6, and lower cross-flow fan 7. During the normal operation, the upper cross-flow fan 6 and the lower cross-flow fan 7 are electrically energized, and a damper 15 is open at the open position of the lower delivery opening, namely the position where a limit switch 17 for open position detection is turned OFF. Next, the operation is changed over to an operation for sleeping time, the lower cross-flow fan 7 stops and at the same time the damper 15 moves to the position of a limit switch 18 for close position detection to close the opening, shutting off the air discharge from the lower position, and, therefore, only the upper discharge constitutes the blast circuit.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a blower device for an air conditioner having two outlets, one in the upper part and one in the lower part.

Conventional technology Conventionally, in this type of air conditioner, the control of the cross-flow fan attached to the upper and lower air outlets always blows air to the upper and lower parts, and only at the initial air volume setting is the crossflow fan installed at the upper and lower air outlets. The air volume was controlled.

In such an air conditioner, when installed on the floor, the amount of air from the upper outlet is generally set to be larger than the amount of air from the lower outlet in order to ensure comfort.

Problems to be Solved by the Invention However, with the configuration of the air conditioner described above, there are times when air is required to be blown from the top, times when air is required to be blown from the bottom, and conversely, air is blown from the top. When you want to prohibit air blowing from the bottom, you need to use the button to control the upper and lower crossflow fans independently.

Particularly when the device is installed on the floor, the wind directly hits the body while sleeping, which is a problem from both health and comfort points of view.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides an air conditioner with an opening/closing damper attached to the lower outlet of the air conditioner to cut off air blowing thereto during sleep operation.

Effect By adopting such an i-formation, it is possible to prevent lower part of the vehicle from blowing out during sleep driving, and the bodily sensation is ideal.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the accompanying drawings.

First, the schematic configuration of the air conditioner will be explained with reference to FIG.

In Fig. 3, 1 is the main body of the air conditioner, and the suction port 2
, an upper air outlet 3 and a lower air outlet 4. Next, the internal structure of the air conditioner main body 1 will be explained with reference to cross-sectional views in FIGS. 1 and 2. Here, FIG. 1 shows a cross section taken along line AA in FIG. 3, and FIG. 2 shows a cross section taken along line BB in FIG. 3. In the figure, the wind circuit inside the air conditioner main body 1 includes an air guider 5, an upper cross flow fan 6,
The upper and lower cross flow fans 6.7 each have a driving motor 8.9.
are each connected. 10 is a mounting plate to which the upper drive motor is fixed. 11 is a mounting plate to which the lower drive motor is fixed. On the front of these, there are a heat exchanger 12, an upper stabilizer 13, and a lower stabilizer 1 that also serves as a water tray.
4 is installed. A damper 15 is installed at the back of the lower air outlet 4 to block the lower air outlet. Further, a motor 16 that drives the damper 15 to open and close the damper 15 is connected to the damper 15. Furthermore, the damper 15 has a damper open position detection limit (SV40) and a damper closed position detection limit 5W1.
8 is provided. Figure 4 shows the circuit diagram. During normal operation, the upper cross-flow fan 6 and the lower cross-flow fan 7 are energized, and the damper 15 is also at the open position of the lower air outlet, that is, the limit for detecting the open position (SV40).
is open at the ○FF position. Next, when switching to sleep operation mode, the lower cross flow fan 7 stops and at the same time the damper 15 moves to the closed position detection limit 5.
It moves to the position W18, closes the opening, and stops, blocking the air from the bottom, forming an air blowing circuit that blows only from the top.

Effects of the Invention As is clear from the above embodiments, the present invention provides an air conditioner having two air outlets at each of the upper and lower parts.
When in sleep operation mode, the air blowing to the lower air outlet is stopped and only the upper ventilation circuit is configured.It eliminates the negative effects on the body during cooling operation and provides comfortable air conditioning, so it is useful. It is a great thing.
