Description

[Detailed explanation of the idea] The present invention relates to an air conditioner.

In recent years, there has been a trend in air source heat pump machines to eliminate the auxiliary heater during heating in order to reduce electrical capacity and operating costs, and to achieve high heating capacity without a heater. High heating capacity cannot be obtained simply by switching to heating operation.

Therefore, in order to obtain high heating capacity, it is necessary to use a type that gives priority to heating capacity, such as using a large capacity compressor or a large heat exchanger and bypassing excess refrigerant during cooling, or to use a type that gives priority to heating capacity, such as using a large capacity compressor or a large heat exchanger, or to use a type that gives priority to heating capacity, such as bypassing excess refrigerant during cooling. Either a small-capacity compressor and a small heat exchanger are used to give priority to cooling capacity, increasing the speed of the fan during heating compared to cooling to increase the air volume.

Therefore, the heating capacity priority type requires a high-capacity compressor and heat exchanger, which increases costs.On the other hand, the cooling capacity priority type requires faster rotation of the blower during heating than during cooling, which increases the cost during heating. The noise is higher than when cooling, so there is a problem no matter which type you use.

The present invention was proposed in view of these circumstances, and it demonstrates high heating capacity without causing particularly high noise during heating, without incurring a large cost increase.
The purpose of the air conditioner is to provide an air conditioner with a good air conditioning feeling, and the air source heat pump type air conditioner is equipped with an upper outlet for cooling and a lower outlet for heating. The lower damper attached to the lower air outlet is interlocked with each other, so that during cooling, the lower damper is fully closed and the upper damper is fully opened, and during heating, the lower damper is fully opened and the upper damper is fully opened. Open the damper slightly without fully closing it.

An embodiment of the present invention will be explained with reference to the drawings.
Figure 1 is a longitudinal cross-sectional view, and Figure 2 is the − of Figure 1.
FIGS. 3 and 4 are partial longitudinal sectional views showing the damper of FIG. 1 opened and closed during cooling and heating, respectively.

In the above figure, 1 is a heat exchanger, 2 is a centrifugal blower, 3 is a blower electric motor, 4 is a dew pan, 5 is an upper air outlet, 6 is a lower air outlet, 7 is an indoor air intake port, and 8 is a lever. , 9 is an upper damper, 10 is a link linking the upper damper 9 and the lower damper 11, 11
12 is a fan suction port plate, 13 is a partition plate, 14 is a fulcrum of the upper damper 9, 15 is a fulcrum of the lower damper 11, and 16 is a skeleton.

In such a structure, when the lever 8 is moved, the upper damper 9 rotates around the upper fulcrum 14, and as the upper damper 9 rotates, the lower damper 11 also rotates around the lower fulcrum 15 by the link 10.
Rotates around the center.

The upper damper 9 has a notch as shown in FIG. 2, but the lower damper 11 does not have a notch.

First, in the case of cooling operation, as shown in Fig. 3, when the lever 8 is rotated clockwise, the link 1
0, the upper damper 9 rotates about the upper fulcrum 14 and is fully opened, and the lower damper 11 rotates about the lower fulcrum 15 and closes. In this case, the lower side is completely blocked by the lower damper 11, so the cold air does not blow out from the lower outlet 6, and since the upper damper 9 is open, the cold air flows only from the upper outlet 5. Speech out.

Next, in the case of heating operation, as shown in FIG. 4, when the lever 8 is rotated counterclockwise, the upper damper 9 closes and the lower damper 11 closes.
is fully opened. However, since the lower damper 9 is provided with a notch, most of the hot air is blown out from the lower outlet 6, but some amount is also blown out from the upper outlet 5 depending on the size of the notch in the upper damper 9. Hot air blows out.

According to this structure, during cooling, cold air is blown out only from the top, and during heating, most of the warm air is blown out from the bottom, and a small amount is also blown out from the top. The temperature distribution will be improved for both cooling and heating.

During cooling, the upper damper 9 is opened and the lower damper 11 is completely closed, so cold air is blown out only in the upward direction. Since it rotates within the casing, the internal static pressure increases. On the other hand, during heating, the upper damper 9 is closed and the lower damper 11 is open, but because the upper damper 9 has a notch, the internal static pressure is lower than during cooling even with the same air volume.

Therefore, in order to exhibit high heating capacity, the noise does not increase even if the rotation speed of the blower during heating is increased compared to during cooling to increase the air volume. The size of the notch can be arbitrarily selected depending on the difference in air volume between cooling and heating and the noise level, and by implementing this invention, high heating capacity can be achieved without increasing cost or noise. be able to.

In the above embodiment, a notch is provided in the upper damper 9 in order to blow out a small amount of hot air from above during heating, but the rotation angle of the damper may be adjusted so that a small amount of hot air is blown out from above during heating.

Further, the damper may be opened and closed by an automatic method driven by a motor instead of a manual method, and various structures can be employed for the combination of links.

In short, according to the present invention, in an air source heat pump type air conditioner equipped with an upper outlet for cooling and a lower outlet for heating, an upper damper attached to the upper outlet and a lower damper attached to the lower outlet. When cooling, the lower damper is fully closed and the upper damper is fully opened; during heating, the lower damper is fully opened, but the upper damper is not fully closed. The present invention is industrially extremely useful because a high-performance air conditioner can be obtained by slightly opening the opening.
