Abstract

PURPOSE:To improve temperature distribution in a resident space and hence shorten building-up time upon starting operation by making variable the swing speed of a diffuser louver and variably control the swing speed in response to an air speed blown out from an diffuser. CONSTITUTION:An output from an air speed sensor 20 which is to detect a blow-off air speed at a diffuser is inputted into swing speed determination means 31 provided in a control device 30, which means then receives an instruction from memory means 32 to determine a swing speed. The memory means 32 has stored therein a swing speed previously set corresponding to an air speed. Further, an output from the swing speed determination means 31 is inputted into pulse duration set means 33, in which a pulse duration is set which is then outputted to a pulse motor 40 for driving the diffuser louver. Thus, the diffuser louver swings at a swing speed corresponding to an air speed, from the diffuser, so that a blow-off air enters the entire region of a resident space to improve temperature distribution in the resident space and shorten building-up time upon starting the operation.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a method of controlling a blowout louver of an air conditioner.

(Prior Art) A longitudinal sectional view of a conventional wall-mounted indoor unit of a separate type air conditioner is shown in FIG.

In Fig. 3, C and l are the main body, 2 is the suction grill provided on the front upper part of the main body 1, 3 is the heat exchanger, 4 is the fan disposed at the bottom rear of the heat exchanger Ia 3, and 5 is the A blowout [J] is provided at the lower front of the main body 1, 6 is a blowout louver provided at the blowout port 5, 7 is a drain pan provided under the heat exchanger 3, and 8 is provided behind the suction grill 2. Air filter installed.

This wall-mounted indoor unit 9 is installed at a predetermined height on the wall 11 of the room 10, as shown in FIG. Refrigerant from an outdoor unit (not shown) is circulated.In this way, indoor air is drawn into the main body 1 through the suction grille 2 as shown by the solid arrow, and is contained therein by passing through the air filter 8. The dust is removed, and in the process of flowing through the heat exchanger 3, it is cooled or heated by exchanging heat with the refrigerant, energized by the fan 4, and then guided from the air outlet 5 to the air outlet louver 6 and into the room. It's blown out.

This blowout louver 6 is driven by a motor (not shown) to swing around a horizontal axis at a constant swing speed, and has a swing range of approximately 90@ from horizontal (0") to vertically downward (90"). It swings back and forth inside.

Further, the rotational speed of the fan 4 is controlled to be different during cooling operation, different between daytime and nighttime, and different between heavy load and light load.

(Problem to be Solved by the Invention) The conventional blow-off louver 6 swings at a constant swing speed regardless of the speed of the cold air or hot air blown out from the blow-off port 5. All of the air is not efficiently blown into the living space 12 shown in FIG. There was a problem with the temperature rising slowly at the start.

(Means for Solving the Problems) The present invention was invented to solve the above problems, and the gist of the present invention is to provide a blow-off louver which is disposed at a blow-off port and swings by being driven by a motor. A method of controlling a blowout louver of an air conditioner, characterized in that the swing speed of the blowout louver is made variable and the swing speed of the blowout louver is variably controlled in accordance with the speed of wind blown out from the blowout port.

(Function) In the present invention, since the above structure is provided, the blowing louver swings at a swing speed corresponding to the blowing wind speed.

(Embodiment) FIG. 1 shows a control block diagram of the blow-off louver.

The output of the sensor 20 for detecting the blowout wind speed, such as the wind speed sensor disposed at the blower outlet 5 or the sensor for detecting the rotational speed of the fan 4, is input to the swing speed determining means 31 provided in the control device 30, where The swing speed is determined in response to a command from the storage means 32. The storage means 32 stores a preset swing speed corresponding to the wind speed. The output of the swing speed determining means 31 is input to the pulse interval setting means 33, which sets the number of pulses generated per unit time, that is, the pulse interval.Then, the output from the pulse interval setting means 33 is input to the output means. The signal is outputted to a pulse motor 40 for driving the blow-off louver 6 via a motor 34 .

The rest of the structure is the same as the conventional one shown in FIGS. 3 and 4.

Thus, the blowout louver 6 swings at a predetermined swing speed depending on the speed of the wind blown out from the blowout port 5. In this way, the blown air spreads over the entire area of the living space 12 shown in FIG. 4, thereby improving the temperature distribution within the living space 12 and shortening the start-up time when the air conditioner starts operating.

Figure 2 shows the relationship between the rise time T and the ratio FV/B of the blowout wind speed 1'i'v and the swing speed B. As is clear from Figure 2, the rise time T can be adjusted to the optimum ratio α. It will be the shortest.

In the above embodiment, the blowout louver 6 is connected to the pulse motor 4.
0, but the scales may of course be driven by variable speed motors of any other type or configuration.

(Effects of the Invention) In the present invention, the swing speed of the blowout louver is made variable and the swing speed of the blowout louver is variably controlled according to the wind speed blown out from the blowout port. It moves 1g.

As a result, the blown air can be spread over the entire area of the living space, improving the temperature distribution of the living space and shortening the start-up time when the air conditioner starts operating.
