Abstract

PROBLEM TO BE SOLVED: To provide an air-conditioner which can increase the heating effect, by making it possible to send warm air to a floor face by a simple means. SOLUTION: Since a projection having a shape memory annoy 35 which is extensible in accordance with the blowing-out temperature is provided at the lower jaw 30 of the blowing-out opening 13, the shape memory alloy 35 stretches by perceiving the warm air temperature when the warm air passes the blowing-out opening 13 and at the same time, the projection sticks toward the lateral blades 25a, 25b side for changing the wind direction. Hence, the blowing-out width of the opening 13 is narrowed. When the blowing-out width of the opening 13 is narrowed, the warm air speed passing the opening is increased and it can reach the floor face and hence, the heating effect can be increased.

Description of the Related Art Conventionally, in an air conditioner intended to enhance the heating effect by directing warm air downward to reach the floor surface, in addition to the two horizontal blades provided at the air outlet, Another side blade (louver) is installed on the windward side,
A louver driven by a louver motor has been proposed.

[0003]

However, the conventional method requires the louver motor as described above,
A drive circuit is required. In addition, incorporating a circuit into a control system by using a louver motor has a problem that the cost is increased because it requires parts such as a motor in addition to the difficulty of creating software. When it is manually moved, there is a problem that it has to be manually operated each time.

Therefore, an object of the present invention is to solve the problems of the above-mentioned conventional techniques, to eliminate the need for a louver motor, to avoid the difficulty of creating software associated therewith, to reduce the cost, and to bother with the manual operation. SUMMARY OF THE INVENTION It is an object of the present invention to provide an air conditioner in which the hot air blown from the air outlet is automatically directed downward so that the hot air can reach the floor surface.

[0005]

In order to achieve the above-mentioned object, the invention according to claim 1 is an air conditioner provided with lateral blades capable of changing the wind direction from downward to substantially horizontal at the outlet. A protrusion that can protrude toward the side of the horizontal blade is provided in the lower jaw of the outlet, and an adjusting unit that adjusts the protrusion size of the protrusion according to the outlet temperature is provided. Is.

According to a second aspect of the present invention, the means for projecting the protrusion has a shape memory alloy that expands and contracts according to the blowing temperature, and the protrusion is directly connected to the shape memory alloy. It is what

The invention according to claim 3 is characterized in that a step portion is provided in the lower jaw portion of the air outlet, and the projecting body is accommodated in the step portion.

According to these aspects of the invention, the adjusting means is, for example, according to the temperature of the air blown through the air outlet of the air conditioner,
Shape memory alloy expands and contracts.

Since this shape memory alloy is directly connected to the protrusion provided on the lower jaw of the air outlet, the protrusion also expands and contracts as the shape memory alloy expands and contracts. For example, when hot air is blown from the outlet, the shape memory alloy expands in response to the temperature of the hot air, and the projection of the lower jaw directly connected to the shape memory alloy also projects toward the side blades. Therefore, the air outlet is narrowed by the amount of protrusion. When the air outlet is narrowed, the flow velocity of the warm air passing through the air outlet is higher than when the air outlet is wide, and the hot air is blown out vigorously, so when the hot air is blown downward, It also makes it possible to reach the floor.

As the warm air is directed downward and reaches the floor surface as described above, the heating effect of the air conditioner is enhanced as compared with the conventional one.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1, an air conditioner 3 according to an embodiment of the present invention includes a heat exchanger 5 into which a refrigerant is introduced, a blower 7, and an air purifier 9 in its case. A suction port 11 is formed on the front and diagonally upper sides of the case, and an air outlet 13 is formed on the diagonally lower front side of the case. A blowout passage 19 for guiding the air after heat exchange, which is surrounded by a bottom plate 15 and a drain pan 17, is formed in the blowout outlet 13, and an airflow direction changing device 23 is provided in the blowout passage 19. There is.

The wind direction changing device 23 comprises a large number of vertical blades 21 arranged substantially in the center of the blowout passage 19, and a pair of wind direction changing horizontal blades 25a, 25b arranged on the blowout side. The vertical blades 21 of the wind direction changing device 23 rotate in the longitudinal direction of the air outlet to change the wind direction changing horizontal blades 25a, 2a.
5b is configured to rotate in the lateral direction of the air outlet so that each can change the wind direction.

According to this embodiment, by utilizing the temperature of the hot air blown from the blowout port 13, the blowout width of the blowout port 13 can be adjusted according to the blowout temperature.
The lower jaw portion 30 is capable of protruding toward the side blades 25a and 25b.

The lower jaw portion 30 is provided at the tip of the bottom plate 15 and faces the outlet 13.
A step portion 15a is formed at the tip of the bottom plate 15,
The step portion 15a is provided with a cover 33 so as to eliminate the step difference of the step portion 15a. This cover 33
As shown in FIG. 2, is connected to the shape memory alloy 35 accommodated in the step portion 15a, and can be freely projected to the side blades 25a and 25b according to expansion and contraction of the shape memory alloy 35.

Reference numeral 33a is connected to the upper portion of the cover 33, and constitutes a guide member when the cover 33 slides on the stepped portion 15a.

Next, the operation will be described. According to this embodiment, the air blown by the blower 7 is the heat exchanger 5
The heat is exchanged, the air flows through the blowout passage 19 toward the blowout port 13, and the blowing direction is adjusted by the wind direction changing device 23 provided in the blowout port 13, and the blowout direction is blown out. The vertical blades 21 are for controlling the left and right wind direction, and the horizontal blades 25a and 25b are for controlling the wind direction from downward to substantially horizontal.

The air whose blowing direction is controlled in this way is
The air passes through the air outlet 13 while being guided by the lower jaw 30 of the air outlet 13.

According to this embodiment, when the temperature of the blown air is, for example, 30 ° C. to 50 ° C., the shape memory alloy 35 located inside the cover 33 expands,
The cover 3 which is a protrusion directly connected to the shape memory alloy 35
As shown in FIG. 2, the reference numeral 3 designates wind direction changing side blades 25a, 2
It extends toward the 5b side. The length of this extension, that is, the protruding size of the cover 33 is adjusted according to the blowing temperature,
The higher the temperature of the blown air, the larger its protruding dimension.

That is, when the temperature of the blown air is high (30 ° C. or higher), the warm air passes through the outlet 13 while being in contact with the lower jaw 30, so that the temperature of the shape memory alloy 35 is felt. Since the cover 33, which is a protrusion that extends and is connected to the shape memory alloy 35, also extends toward the wind direction changing side blades 25a and 25b, the outlet 13 becomes narrower as shown in FIG.

If the outlet 13 becomes narrower, the velocity of the warm air passing therethrough will increase, so that the warm air can reach the floor surface if the blowing direction of the warm air is controlled downward. become. Normally, warm air stays at the top and cold air stays at the bottom, so reaching the floor surface with warm air can warm the feet as well, improving the heating effect compared to the conventional one. be able to.

In short, according to this embodiment, the cover 33 automatically protrudes as shown in FIG. 2 in accordance with the temperature of the hot air blown out during the heating operation.
Without the use of possible tedious actuators,
The wind speed can be increased and the warm air can be efficiently collected at the feet.

During the cooling operation, the temperature of the hot air blown out is naturally lower than the predetermined temperature, so that the shape memory alloy 35 expands and contracts, and the cover 33 is accordingly expanded as shown in FIG. And is accommodated in the step portion 15a.

The present invention has been described above based on the embodiment, but the present invention is not limited to this.
For example, it is obvious that a means other than the shape memory alloy 35, for example, a motor may be used as the means for projecting the cover 33 toward the side blades 25a, 25b.

[0025]

As is apparent from the above description, according to these inventions, the lower jaw of the outlet has the adjusting means for adjusting the outlet width according to the outlet temperature.
When the air blown from the outlet is warm air, the blowing width of the outlet narrows in response to the temperature, so the velocity of the warm air passing through the outlet increases, so the warm air blown out By controlling the blowing direction of the air flow downward, it is possible that the warm air reaches the floor surface as well, because warm air is usually located above and cold air is located below, so warm air reaches the floor surface. By doing so, even the feet are warmed, so a higher heating effect can be obtained compared to the conventional one.
